2.1Â Â Â Â Â Â Â General organization
Each channel has its own coding and interleaving scheme. However, the channel coding and interleaving is organized in such a way as to allow, as much as possible, a unified decoder structure.
Each channel uses the following sequence and order of operations:
â    the information bits are coded with a systematic block code, building words of information + parity bits;
â    these information + parity bits are encoded with a convolutional code or a turbo code, building the coded bits;
â    reordering and interleaving the coded bits, and adding a stealing flag, gives the interleaved bits.
All these operations are made block by block, the size of which depends on the channel. However, most of the channels use a block of either 456 coded bits or 1368 coded bits, corresponding to 456 coded symbols, which is interleaved and mapped onto bursts in a very similar way for all of them. This block of 456 coded symbols is the basic structure of the channel coding scheme. Figures 1a, 1b, 1c, 1d, 1e, 1f, 1g, 1h, 1i, 1j, 1k, 1l and 2 give diagrams showing the general structure of the channel coding.
In the case of full rate speech TCH, a block of 456 coded bits carries the information of one speech frame. In case of control channels, it carries one message.
In the case of half rate speech TCH, the information of one speech frame is carried in a block of 228 coded bits.
In the case of the Enhanced full rate speech the information bits coming out of the source codec first go through a preliminary channel coding. Then the channel coding as described above takes place.
In the case of 8-PSK modulated speech TCH, the information of one speech frame is carried in a block of 1368 coded bits (456 coded symbols) for full rate channels or 684 coded bits (228 coded symbols) for half rate channels.
In the case of a packet switched channel the block of 456, 1096, 1384, 1848, 2200, 2312 or 2748 coded bits carries one radio block.
In the case of E-TCH/F28.8 or E-TCH/F43.2, the block of 1368 coded bits (456 coded symbols) carries one radio block. In the case of E-TCH/F32.0, the block of 1392 coded bits (464 coded symbols) carries one radio block.
In the case of FACCH, a coded message block of 456 bits is divided into eight subâblocks. The first four subâblocks are sent by stealing the even numbered bits of four timeslots in consecutive frames used for the TCH. The other four subâblocks are sent by stealing the odd numbered bits of the relevant timeslot in four consecutive used frames delayed 2 or 4 frames relative to the first frame. Along with each block of 456 coded bits there is, in addition, a stealing flag (8 bits), indicating whether the block belongs to the TCH or to the FACCH. In the case of SACCH, BCCH, CCCH or CTSCCH, this stealing flag is dummy. In the case of a packet switched channel, these bits are used to indicate the coding scheme used.
In the case of E-FACCH/F, a coded message block of 456 bits is divided into four sub-blocks. The four sub-blocks are sent by stealing all symbols of four timeslots in consecutive frames used for the E-TCH and using GMSK modulation. The indication of the E-FACCH/F is based on the identification of the modulation. Along with each block of 456 coded bits there is, in addition, a stealing flag (8 bits), indicating whether the block belongs to the E-FACCH, FACCH or TCH.
Some cases do not fit in the general organization, and use short blocks of coded bits which are sent completely in one timeslot. They are the random access messages of:
-Â Â Â Â the RACH;
-Â Â Â Â or PRACH, CPRACH and MPRACH;
on uplink and the synchronization information broadcast on the SCH or CSCH on the downlink. In CTS, they are the access request message of the CTSARCH on uplink and the information broadcast on the CTSBCH-SB on downlink.
In the coding/multiplexing unit of FLO, error detection, forward error correction and rate matching is applied to each transport channel independently. However the transport channels share a common multiplexing, TFCI mapping, interleaving and burst mapping. All these operations are made every transmission time interval and the number of coded bits produced by the coding/multiplexing unit depends on the basic physical subchannel. In the case of full rate GMSK basic physical subchannel, blocks of 464 bits are produced. In the case of half rate GMSK basic physical subchannel, blocks of 232 bits are produced. In the case of full rate 8PSK basic physical subchannel, blocks of 1392 bits are produced. In the case of half rate 8PSK basic physical subchannel, blocks of 696 bits are produced.

Two kinds of traffic channel are considered: speech and data. Both of them use the same general structure (see figure 1), and in both cases, a piece of information can be stolen by the FACCH.
3.1Â Â Â Â Â Â Â Speech channel at full rate (TCH/FS and TCH/EFS)
The speech coder (whether Full rate or Enhanced full rate) delivers to the channel encoder a sequence of blocks of data. In case of a full rate and enhanced full rate speech TCH, one block of data corresponds to one speech frame.
For the full rate coder each block contains 260 information bits, including 182 bits of class 1 (protected bits), and 78 bits of class 2 (no protection), (see table 2).
The bits delivered by the speech coder are received in the order indicated in 3GPP TS 46.010 and have to be rearranged according to table 2 before channel coding as defined in subclauses 3.1.1 to 3.1.4. The rearranged bits are labelled {d(0),d(1),...,d(259)}, defined in the order of decreasing importance.
For the EFR coder each block contains 244 information bits. The block of 244 information bits, labelled s(1).., s(244), passes through a preliminary stage, applied only to EFR (see figure 1) which produces 260 bits corresponding to the 244 input bits and 16 redundancy bits. Those 16 redundancy bits correspond to 8 CRC bits and 8 repetition bits, as described in subclause 3.1.1. The 260 bits, labelled w(1)..w(260), have to be rearranged according to table 6 before they are delivered to the channel encoding unit which is identical to that of the TCH/FS. The 260 bits block includes 182 bits of class 1(protected bits) and 78 bits of class 2 (no protection). The class 1 bits are further divided into the class 1a and class 1b, class 1a bits being protected by a cyclic code and the convolutional code whereas the class 1b are protected by the convolutional code only.
3.1.1Â Â Â Â Â Â Preliminary channel coding for EFR only
3.1.1.1Â Â Â Â Â Â Â Â Â Â Â CRC calculation
An 8âbit CRC is used for errorâdetection. These 8 parity bits (bits w253âw260) are generated by the cyclic generator polynomial: g(D) = D8Â + D4Â + D3Â + D2Â + 1 from the 65 most important bits (50 bits of class 1a and 15 bits of class 1b). These 65 bits (b(1)âb(65)) are taken from the table 5 in the following order (read row by row, left to right):

The encoding is performed in a systematic form, which means that, in GF(2), the polynomial:
-Â Â Â Â b(1)D72 + b(2)D71 +...+b(65)D8 + p(1)D7 + p(2)D6 +...+ p(7)D1 + p(8);
-Â Â Â Â p(1) â p(8): the parity bits (w253âw260);
-Â Â Â Â b(1) â b(65) = the data bits from the table above;
when divided by g(D), yields a remainder equal to 0.
3.1.1.2Â Â Â Â Â Â Â Â Â Â Â Repetition bits
The repeated bits are s70, s120, s173 and s223. They correspond to one of the bits in each of the PULSE_5, the most significant one not protected by the channel coding stage.
3.1.1.3Â Â Â Â Â Â Â Â Â Â Â Correspondence between input and output of preliminary channel coding
The preliminary coded bits w(k) for k = 1 to 260 are hence defined by:
w(k) = s(k)Â Â Â Â Â for k = 1 to 71
w(k) = s(kâ2) for k = 74 to 123
w(k) = s(kâ4) for k = 126 to 178
w(k) = s(kâ6) for k = 181 to s230
w(k) = s(kâ8) for k = 233 to s252
Repetition bits:
w(k) = s(70)Â Â for k = 72 and 73
w(k) = s(120) for k = 124 and 125
w(k) = s(173) for k = 179 and 180
w(k) = s(223) for k = 231 and 232
Parity bits:Â Â Â Â Â
w(k = p(kâ252) for k = 253 to 260
3.1.2Â Â Â Â Â Â Channel coding for FR and EFR
3.1.2.1Â Â Â Â Â Â Â Â Â Â Â Parity and tailing for a speech frame
a)Â Â Parity bits:
     The first 50 bits of class 1 (known as class 1a for the EFR) are protected by three parity bits used for error detection. These parity bits are added to the 50 bits, according to a degenerate (shortened) cyclic code (53,50,2), using the generator polynomial:
g(D) = D3Â + D + 1
     The encoding of the cyclic code is performed in a systematic form, which means that, in GF(2), the polynomial:
d(0)D52Â + d(1)D51Â +... + d(49)D3Â + p(0)D2Â + p(1)D+ p(2)
     where p(0), p(1), p(2) are the parity bits, when divided by g(D), yields a remainder equal to:
1 + D + D2
b)Â Â Tailing bits and reordering:
     The information and parity bits of class 1 are reordered, defining 189 information + parity + tail bits of class 1, {u(0),u(1),...,u(188)} defined by:
     u(k)                 = d(2k)     and     u(184âk) = d(2k+1)         for k = 0,1,...,90
     u(91+k)          = p(k)                                                                for k = 0,1,2
     u(k)                 = 0                                                                     for k = 185,186,187,188 (tail bits)
3.1.2.2Â Â Â Â Â Â Â Â Â Â Â Convolutional encoder
The class 1 bits are encoded with the ½ rate convolutional code defined by the polynomials:
G0 = 1 + D3+ D4
G1 = 1 + D + D3+ D4
The coded bits {c(0), c(1),..., c(455)} are then defined by:
â class 1:Â Â c(2k)Â Â =Â Â Â Â Â Â Â Â Â u(k) + u(kâ3) + u(kâ4)
                  c(2k+1)    =   u(k) + u(kâ1) + u(kâ3) + u(kâ4)       for      k = 0,1,...,188
                                           u(k) = 0 for k < 0
â    class 2:     c(378+k) = d(182+k)                 for k = 0,1,....,77
3.1.3Â Â Â Â Â Â Interleaving
The coded bits are reordered and interleaved according to the following rule:
i(B,j) = c(n,k),     for k = 0,1,...,455
                        n = 0,1,...,N,N+1,...
                        B = B0 + 4n + (k mod 8)
                        j  = 2((49k) mod 57) + ((k mod 8) div 4)
See table 1. The result of the interleaving is a distribution of the reordered 456 bits of a given data block, n = N, over 8 blocks using the even numbered bits of the first 4 blocks (B = B0Â + 4N + 0, 1, 2, 3) and odd numbered bits of the last 4 blocks (B = B0Â + 4N + 4, 5, 6, 7). The reordered bits of the following data block, n = N+1, use the even numbered bits of the blocks B = B0Â + 4N + 4, 5, 6, 7 (B = B0Â + 4(N+1) + 0, 1, 2, 3) and the odd numbered bits of the blocks B = B0Â + 4(N+1) + 4, 5, 6, 7. Continuing with the next data blocks shows that one block always carries 57 bits of data from one data block (n = N) and 57 bits of data from the next block (n = N+1), where the bits from the data block with the higher number always are the even numbered data bits, and those of the data block with the lower number are the odd numbered bits.
The block of coded data is interleaved "block diagonal", where a new data block starts every 4th block and is distributed over 8 blocks.
3.1.4Â Â Â Â Â Â Mapping on a Burst
The mapping is given by the rule:
e(B,j)    = i(B,j)  and    e(B,59+j) = i(B,57+j)            for j = 0,1,...,56
and
e(B,57) = hl(B)   and    e(B,58) = hu(B)
The two bits, labelled hl(B) and hu(B) on burst number B are flags used for indication of control channel signalling. For each TCH/FS block not stolen for signalling purposes:
hu(B) = 0 for the first 4 bursts (indicating status of even numbered bits)
hl(B) = 0 for the last 4 bursts  (indicating status of odd numbered bits)
For the use of hl(B) and hu(B) when a speech frame is stolen for signalling purposes see subclause 4.2.5.
3.2Â Â Â Â Â Â Â Speech channel at half rate (TCH/HS)
The speech coder delivers to the channel encoder a sequence of blocks of data. In case of a half rate speech TCH, one block of data corresponds to one speech frame. Each block contains 112 bits, including 95 bits of class 1 (protected bits), and 17 bits of class 2 (no protection), see tables 3a and 3b.
The bits delivered by the speech coder are received in the order indicated in 3GPP TS 46.020 and have to be arranged according to either table 3a or table 3b before channel encoding as defined in subclauses 3.2.1 to 3.2.4. The rearranged bits are labelled {d(0),d(1),...,d(111)}. Table 3a has to be taken if parameter Mode = 0 (which means that the speech encoder is in unvoiced mode), while table 3b has to be taken if parameter Mode = 1, 2 or 3 (which means that the speech encoder is in voiced mode).
3.2.1Â Â Â Â Â Â Parity and tailing for a speech frame
a)Â Â Parity bits:
     The most significant 22 class 1 bits d(73),d(74),...,d(94) are protected by three parity bits used for error detection. These bits are added to the 22 bits, according to a cyclic code using the generator polynomial:
     g(D) = D3 + D + 1
     The encoding of the cyclic code is performed in a systematic form, which means that, in GF(2), the polynomial:
     d(73)D24 + d(74)D23 + ... + d(94)D3 + p(0)D2 + p(1)D + p(2)
     where p(0), p(1), p(2) are the parity bits, when divided by g(D), yields a remainder equal to:
     1 + D + D2.
b)Â Â Tail bits and reordering:
     The information and parity bits of class 1 are reordered, defining 104 information + parity + tail bits of class 1, {u(0),u(1),...,u(103)} defined by:
u(k) = d(k)Â Â Â Â Â Â Â Â Â Â Â for k = 0,1,...,94
u(k) = p(kâ95)Â Â Â Â Â for k = 95,96,97
u(k) = 0Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â for k = 98,99,...,103 (tail bits)
3.2.2Â Â Â Â Â Â Convolutional encoder
The class 1 bits are encoded with the punctured convolutional code defined by the mother polynomials:
     G4 = 1 + D2 + D3 + D5 + D6
     G5 = 1 + D + D4 + D6
     G6 = 1 + D + D2 + D3 + D4 + D6
and the puncturing matrices:
     (1,0,1)      for {u(0),u(1),...,u(94)} (class 1 information bits);
                        and {u(98),u(99),...,u(103)} (tail bits).
     (1,1,1)      for {u(95),u(96),u(97)} (parity bits)
In the puncturing matrices, a 1 indicates no puncture and a 0 indicates a puncture.
The coded bits {c(0),c(1),...,c(227)} are then defined by:
     class 1 information bits:
c(2k)Â Â Â Â Â Â Â Â Â = u(k)+u(kâ2)+u(kâ3)+ (kâ5)+u(kâ6)
c(2k+1)Â Â Â Â = u(k)+u(kâ1)+u(kâ2)+u(kâ3)+u(kâ4)+u(kâ6)Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â for k = 0,1,...,94;u(k) = 0 for k<0
     parity bits:
c(3kâ95)Â Â Â = u(k)+u(kâ2)+u(kâ3)+u(kâ5)+u(kâ6)
c(3kâ94)Â Â Â = u(k)+u(kâ1)+u(kâ4)+u(kâ6)
c(3kâ93)Â Â Â = u(k)+u(kâ1)+u(kâ2)+u(kâ3)+u(kâ4)+u(kâ6)Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â for k = 95,96,97
     tail bits:
c(2k+3)Â Â Â Â = u(k)+u(kâ2)+u(kâ3)+u(kâ5)+u(kâ6)
c(2k+4)Â Â Â Â = u(k)+u(kâ1)+u(kâ2)+u(kâ3)+u(kâ4)+u(kâ6)Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â for k = 98,99,...,103
     class 2 information bits:
c(k+211)Â Â = d(k+95) for k = 0,1,...,16
3.2.3Â Â Â Â Â Â Interleaving
The coded bits are reordered and interleaved according to the following rule:
     i(B,j) = c(n,k)      for      k = 0,1,...,227
                                                 n = 0,1,...,N,N+1,...
                                                 B = B0 + 2n + b
The values of b and j in dependence of k are given by table 4.
The result of the interleaving is a distribution of the reordered 228 bits of a given data block, n = N, over 4 blocks using the even numbered bits of the first 2 blocks (B = B0+2N+0,1) and the odd numbered bits of the last 2 blocks (B = B0+2N+2,3). The reordered bits of the following data block, n = N + 1, use the even numbered bits of the blocks B = B0 + 2N + 2,3 (B = B0+2(N+1)+0,1) and the odd numbered bits of the blocks B = B0 + 2(N+1) + 2,3. Continuing with the next data blocks shows that one block always carries 57 bits of data from one data block (n = N) and 57 bits from the next block (n = N+1), where the bits from the data block with the higher number always are the even numbered data bits, and those of the data block with the lower number are the odd numbered bits. The block of coded data is interleaved "block diagonal", where a new data block starts every 2nd block and is distributed over 4 blocks.
3.2.4Â Â Â Â Â Â Mapping on a burst
The mapping is given by the rule:
     e(B,j) = i(B,j) and e(B,59+j) = i(B,57+j) for j = 0,1,...,56
and
     e(B,57) = hl(B) and e(B,58) = hu(B)
The two bits, labelled hl(B) and hu(B) on burst number B are flags used for indication of control channel signalling. For each TCH/HS block not stolen for signalling purposes:
     hu(B) = 0 for the first 2 bursts (indicating status of the even numbered bits)
     hl(B) = 0 for the last 2 bursts (indicating status of the odd numbered bits)
For the use of hl(B) and hu(B) when a speech frame is stolen for signalling purposes, see subclause 4.3.5.
3.3Â Â Â Â Â Â Â Data channel at full rate, 12.0 kbit/s radio interface rate (9.6 kbit/s services (TCH/F9.6))
The definition of a 12.0 kbit/s radio interface rate data flow for data services is given in 3GPP TS 44.021.
3.3.1Â Â Â Â Â Â Interface with user unit
The user unit delivers to the encoder a bit stream organized in blocks of 60 information bits (data frames) every 5 ms. Four such blocks are dealt with together in the coding process {d(0),...,d(239)}. For nonâtransparent services those four blocks shall align with one 240âbit RLP frame.
3.3.2Â Â Â Â Â Â Block code
The block of 4 * 60 information bits is not encoded, but only increased with 4 tail bits equal to 0 at the end of the block.
u(k) = d(k)Â Â Â Â Â Â Â Â Â Â Â for k = 0,1,...,239
u(k) = 0Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â for k = 240,241,242,243 (tail bits)
3.3.3Â Â Â Â Â Â Convolutional encoder
This block of 244 bits {u(0),...,u(243)} is encoded with the ½ rate convolutional code defined by the following polynomials:
     G0 = 1 + D3 + D4
     G1 = 1 + D + D3+ D4
resulting in 488 coded bits {C(0), C(1),..., C(487)} with
     C(2k)        = u(k) + u(kâ3) + u(kâ4)
     C(2k+1)   = u(k) + u(kâ1) + u(kâ3) + u(kâ4)   for k = 0,1,...,243 ; u(k) = 0 for k < 0
The code is punctured in such a way that the following 32 coded bits:
     {C(11+15j) for j = 0,1,...,31} are not transmitted.
The result is a block of 456 coded bits, {c(0),c(1),..., c(455)}
3.3.4Â Â Â Â Â Â Interleaving
The coded bits are reordered and interleaved according to the following rule:
i(B,j) = c(n,k) for k =
0,1,...,455Â Â Â Â Â
                  n = 0,1,...,N,N + 1,...    Â
                  B = B0 +4n + (k mod 19) + (k div 114)   Â
                  j  = (k mod 19) + 19 (k mod 6)
The result of the interleaving is a distribution of the reordered 114 bit of a given data block, n = N, over 19 blocks, 6 bits equally distributed in each block, in a diagonal way over consecutive blocks.
Or in other words the interleaving is a distribution of the encoded, reordered 456 bits from four given input data blocks, which taken together give n = N, over 22 bursts, 6 bits equally distributed in the first and 22nd bursts, 12 bits distributed in the second and 21st bursts, 18 bits distributed in the third and 20th bursts and 24 bits distributed in the other 16 bursts.
The block of coded data is interleaved "diagonal", where a new block of coded data starts with every fourth burst and is distributed over 22 bursts.
3.3.5Â Â Â Â Â Â Mapping on a Burst
The mapping is done as specified for TCH/FS in subclause 3.1.4. On bitstealing by a FACCH, see subclause 4.2.5.

3.4.1Â Â Â Â Â Â Interface with user unit
The user unit delivers to the encoder a bit stream organized in blocks of 60 information bits (data frames) every 10 ms, {d(0),d(1),...,d(59)}.
In the case where the user unit delivers to the encoder a bit stream organized in blocks of 240 information bits every 40 ms (e.g. RLP frames), the bits {d(0),d(1),...,d(59),d(60),...,d(60+59), d(2*60),...,d(2*60+59), d(3*60),...,d(3*60+59)} shall be treated as four blocks of 60 bits each as described in the remainder of this clause. To ensure endâtoâend synchronization of the 240 bit blocks, the resulting block after coding of the first 120 bits {d(0),d(1),...,d(60+59)} shall be transmitted in one of the transmission blocks B0, B2, B4 of the channel mapping defined in 3GPP TS 45.002.
3.4.2Â Â Â Â Â Â Block code
Sixteen bits equal to 0 are added to the 60 information bits, the result being a block of 76 bits, {u(0),u(1),...,u(75)}, with:
u(19k+p) = d(15k+p)Â Â Â Â Â for k = 0,1,2,3 and p = 0,1,...,14;
u(19k+p) = 0Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â for k = 0,1,2,3 and p = 15,16,17,18.
Two such blocks forming a block of 152 bits {u'(0),u'(1),...,u'(151)} are dealt with together in the rest of the coding process:
u'(k)          = u1(k),   k = 0,1,...,75 (u1 = 1st block)
u'(k+76)   = u2(k),   k = 0,1,...,75 (u2 = 2nd block)

G1 = 1 + D + D3Â + D4
G2 = 1 + D2Â + D4
G3 = 1 + D + D2Â + D3Â + D4
The result is a block of 3 * 152 = 456 coded bits, {c(0),c(1),...,c(455)}:
     c(3k)         = u'(k) + u'(kâ1) + u'(kâ3) + u'(kâ4)
     c(3k+1)    = u'(k) + u'(kâ2) + u'(kâ4)
     c(3k+2)    = u'(k) + u'(kâ1) + u'(kâ2) + u'(kâ3) + u'(kâ4)   for      k = 0,1,...,151;

3.9.1Â Â Â Â Â Â SID_UPDATE
The speech encoder delivers 35 bits of comfort noise parameters. Also delivered is two in-band channels, id0(0,1) and id1(0,1), id0 corresponding to Mode Commands or Mode Requests and id1 to Mode Indication. The general coding is as: the two in-band data channels are coded to 16 bits each, a 14-bit CRC is added to the 35 CN bits which are then coded by a rate ¼ RSC coder to 212 bits. Finally a 212 bit identification field is added thereby giving a total size of 456 bits. These 456 bits are then block interleaved in the same way as SACCH frames.
3.9.1.1Â Â Â Â Â Â Â Â Â Â Â Coding of in-band data
The two in-band data fields, id0(0,1) and id1(0,1), are encoded, giving ic0(0..15) and ic1(0..15).
The ic0 and ic1 data is moved to the coded data c as:
            c(k) = ic0(k)                    for k = 0,1,2,3
            c(k) = ic1(k-4)                 for k = 4, 5, 6, 7
            c(k) = ic0(k-4)                 for k = 8, 9, 10, 11
            c(k) = ic1(k-8)                 for k = 12, 13, 14, 15
            c(k) = ic0(k-8)                 for k = 16, 17, 18, 19
            c(k) = ic1(k-12)              for k = 20, 21, 22, 23
            c(k) = ic0(k-12)              for k = 24, 25, 26, 27
            c(k) = ic1(k-16)              for k = 28, 29, 30, 31
3.9.1.2Â Â Â Â Â Â Â Â Â Â Â Parity and convolutional encoding for the comfort noise parameters
a)Â Â Parity bits:
     A 14-bit CRC is used for error-detection. These 14 parity bits are generated by the cyclic generator polynomial: g(D) = D14 + D13 + D5 + D3 + D2 +1 from the 35 comfort noise parameter bits. The encoding of the cyclic code is performed in a systematic form, which means that, in GF(2), the polynomial:
d(0)D(48) + d(1)D(47) +... + d(34)D(14) + p(0)D(13) +â¦+ p(12)D+ p(13)
where p(0), p(1) ⦠p(13) are the parity bits, when divided by g(D), yields a remainder equal to 1+ D + D2 + D3 + D4 + D5 + D6 + D7 + D8 + D9 + D10 + D11 + D12+ D13
     The information and parity bits are merged:
     u(k) = d(k)                        for k = 0, 1, â¦, 34
     u(k) = p(k-35)                 for k = 35, 36, â¦, 48
b)Â Â Convolutional encoder
     The comfort noise parameters with parity bits (u(0..48)) are encoded with the ¼ rate
     convolutional code defined by the polynomials:
            G1/G3  = 1 + D + D3 + D4 / 1 + D + D2 + D3 + D4
            G2/G3 = 1 + D2 + D4 / 1 + D + D2 + D3 + D4
            G3/G3 = 1
            G3/G3 = 1
     resulting in 212 coded bits, {C(0)⦠C(211)} defined by:
            r(k)            = u(k) + r(k-1) + r(k-2) + r(k-3) + r(k-4)
          C(4k)        = r(k) + r(k-1) + r(k-3) + r(k-4)

This block of data is moved to the coded data (c) as:

     c(8*k+33)      = C(4*k+1)
     c(8*k+34)      = C(4*k+2)

3.9.1.3Â Â Â Â Â Â Â Â Â Â Â Identification marker
The identification marker, IM(0..211), is constructed by repeating the following 9-bit sequence: { 0, 1, 0, 0, 1, 1, 1, 1, 0 } 24 times and then discarding the last 4 bits. This block of data is moved to the coded data (c) as:
     c(8*k+36)      = IM(4*k)
     c(8*k+37)      = IM(4*k+1)
     c(8*k+38)      = IM(4*k+2)
     c(8*k+39)      = IM(4*k+3)                   for k = 0, 1, ..., 52
3.9.1.4Â Â Â Â Â Â Â Â Â Â Â Interleaving
The interleaving is done as specified for the SACCH in subclause 4.1.4.
3.9.1.5Â Â Â Â Â Â Â Â Â Â Â Mapping on a Burst
The interleaving is done as specified for the SACCH in subclause 4.1.5 with the exception that hl(B) and hu(B) is set to "0".
3.9.2Â Â Â Â Â Â SID_FIRST
This frame type contains no source data from the speech coder, what is transmitted is the in-band channel (signalling Mode Indication or Mode Command/Mode Request depending on the current frame number) and an identification marker.
3.9.2.1Â Â Â Â Â Â Â Â Â Â Â Coding of in-band data
The in-band data, id(0,1), is encoded to ic(0..15) which is moved to the coded data c as:
            c(k) = ic(k)                for k = 0,1,2,3
            c(k) = ic(k-4)             for k = 8, 9, 10, 11
            c(k) = ic(k-8)             for k = 16, 17, 18, 19
            c(k) = ic(k-12)          for k = 24, 25, 26, 27
3.9.2.2Â Â Â Â Â Â Â Â Â Â Â Identification marker
The identification marker, IM(0..211), is constructed by repeating the following 9-bit sequence: { 0, 1, 0, 0, 1, 1, 1, 1, 0 } 24 times and then discarding the last 4 bits. This block of data is moved to the coded data (c) as:
     c(8*k+32)      = IM(4*k)
     c(8*k+33)      = IM(4*k+1)
     c(8*k+34)      = IM(4*k+2)
     c(8*k+35)      = IM(4*k+3)             for k = 0, 1, ..., 52
3.9.2.3Â Â Â Â Â Â Â Â Â Â Â Interleaving
The interleaving is done as specified for the TCH/FS in subclause 3.1.3.
3.9.2.4Â Â Â Â Â Â Â Â Â Â Â Mapping on a Burst
The mapping is done as specified for the TCH/FS in subclause 3.1.4. The last 4 bursts shall not be transmitted unless the SID_FIRST frame is immediately followed by a speech frame.
3.9.3Â Â Â Â Â Â ONSET
Onset frames are used to preset the interleaver buffer after a period of no speech activity in DTX mode. This frame type contains no source data from the speech coder, what is transmitted is the in-band channel signalling the Mode Indication for the speech frame following the onset marker.
3.9.3.1Â Â Â Â Â Â Â Â Â Â Â Coding of in-band data
The in-band data, Mode Indication id1(0,1), is encoded to ic1(0..15). This sequence is then repeated 14 times more, and the last 12 bits are discarded (15*16-12=228) giving the sequence ic1(0..227).
This sequence is then moved to c as:
     c(8*k+4)  = ic1(4*k)
     c(8*k+5)  = ic1(4*k+1)
     c(8*k+6)  = ic1(4*k+2)
     c(8*k+7)  = ic1(4*k+3)             for k = 0, 1, ..., 56
3.9.3.2Â Â Â Â Â Â Â Â Â Â Â Interleaving
The coded bits are reordered and interleaved according to the following rule:
i(B,j) = c(n,k),     for k = 4,5,6,7, 12,13,14,15,20,21,22,23 ...,455
                               n = 0,1,...,N,N+1,...
                               B = B0 + 4n + (k mod 8) - 4
                               j  = 2((49k) mod 57) + ((k mod 8) div 4)
See table 1. The result of the interleaving is a distribution of the defined 228 bits of a given data block of size 456 bits, n = N, over 4 blocks using the odd numbered bits. The even numbered bits of these 4 blocks will be filled by the speech frame for which this frame is the ONSET.
3.9.3.3Â Â Â Â Â Â Â Â Â Â Â Mapping on a Burst
The mapping is given by the rule:
e(B,j)    = i(B,j)  and    e(B,59+j) = i(B,57+j)            for j = 0,1,...,56
and
e(B,57) = hl(B)
The bit labelled hl(B) on burst number B is a flag used for indication of control channel signalling. For each ONSET block not stolen for signalling purposes:
hl(B) = 0 for the 4 bursts   (indicating status of odd numbered bits)
For the use of hl(B) when an ONSET is stolen for signalling purposes see subclause 4.2.5.
3.9.4Â Â Â Â Â Â SPEECH
The speech coder delivers to the channel encoder a sequence of blocks of data. One block of data corresponds to one speech frame and the block length is different in each of the eight channel codec modes. Adjoining each block of data is information of the channel codec mode to use when encoding the block. Also delivered is the in-band data id(0,1) representing Mode Indication or Mode Command/Mode Request depending on the current frame number.
3.9.4.1Â Â Â Â Â Â Â Â Â Â Â Coding of the in-band data
The two input in-band bits (id(0,1)) are coded to eight coded in-band bits (ic(0..7)).
The encoded in-band bits are moved to the coded bits, c, as
     c(k) = ic(k)          for k = 0, 1, ..., 7.
3.9.4.2Â Â Â Â Â Â Â Â Â Â Â Ordering according to subjective importance
The bits delivered by the speech encoder, {s(1),s(2),...,s(Ks)}, are rearranged according to subjective importance before channel coding. Tables 7 to 16 define the correct rearrangement for the speech codec modes 12.2 kbit/s, 10.2 kbit/s, 7.95 kbit/s, 7.40 kbit/s, 6.70 kbit/s, 5.90 kbit/s, 5.15 kbit/s and 4.75 kbit/s, respectively. In the tables speech codec parameters are numbered in the order they are delivered by the corresponding speech encoder according to 3GPP TS 26.090 and the rearranged bits are labelled {d(0),d(1),...,d(Kd-1)}, defined in the order of decreasing importance. Index Kd refers to the number of bits delivered by the speech encoder, see below:

The ordering algorithm is in pseudo code as:
     for j = 0 to Kd-1  d(j) := s(table(j)+1);             where table(j) is read line by line left to right
The rearranged bits are further divided into two different classes to perform unequal error protection for different bits according to subjective importance.
The protection classes are:
     1a -    Data protected with the CRC
and the convolution code.
1b -Â Â Â Â Data protected with the convolution code.
No unprotected bits are used.
The number of class 1 (sum of class 1a and 1b), class 1a and class 1b bits for each codec mode is shown below:

A 6-bit CRC is used for error-detection. These 6 parity bits are generated by the cyclic generator polynomial: g(D) = D6 + D5 + D3 + D2 + D1 + 1 from the first Kd1a bits of class 1, where Kd1a refers to number of bits in protection class 1a as shown above for each codec mode. The encoding of the cyclic code is performed in a systematic form, which means that, in GF(2), the polynomial:
d(0)D(Kd1a+5) + d(1)D(Kd1a+4) +... + d(Kd1a-1)D(6) + p(0)D(5) +â¦+ p(4)D+ p(5)
where p(0), p(1) ⦠p(5) are the parity bits, when divided by g(D), yields a remainder equal to:
1+ D + D2 + D3 + D4 + D5.
The information and parity bits are merged:
u(k) = d(k)                        for k = 0, 1, â¦, Kd1a-1
u(k) = p(k-Kd1a)              for k = Kd1a, Kd1a+1, â¦, Kd1a+5
u(k) = d(k-6)                    for k = Kd1a+6, Kd1a+7, â¦, Ku-1
Thus, after the first encoding step u(k) will be defined by the following contents for each codec mode:
TCH/AFS12.2:
            u(k) = d(k)                        for k = 0, 1, â¦, 80
            u(k) = p(k-81)                  for k = 81, 82, â¦, 86

            u(k) = d(k-6)                    for k = 71, 72, ..., 209
TCH/AFS7.95:
            u(k) = d(k)                        for k = 0, 1, â¦, 74
            u(k) = p(k-75)                  for k = 75, 76, â¦, 80
            u(k) = d(k-6)                    for k = 81, 82, â¦, 164

            u(k) = p(k-61)                  for k = 61, 62, â¦, 66
            u(k) = d(k-6)                    for k = 67, 68, â¦, 153

            u(k) = d(k)                        for k = 0, 1, â¦, 54
            u(k) = p(k-55)                  for k = 55, 56, â¦, 60
            u(k) = d(k-6)                    for k = 61, 62, â¦, 139
TCH/AFS5.9:
            u(k) = d(k)                        for k = 0, 1, â¦, 54
            u(k) = p(k-55)                  for k = 55, 56, â¦, 60

TCH/AFS4.75:
            u(k) = d(k)                        for k = 0, 1, ..., 38
            u(k) = p(k-39)                  for k = 39, 40, ..., 44
            u(k) = d(k-6)                    for k = 45, 46, ..., 100

Below the coding for each codec mode is specified in detail.
TCH/AFS12.2:
     The block of 250 bits {u(0)⦠u(249)} is encoded with the ½ rate convolutional code defined by    the following polynomials:
            G0/G0 = 1
            G1/G0 = 1 + D + D3+ D4 / 1 + D3 + D4
     resulting in 508 coded bits, {C(0)⦠C(507)} defined by:
            r(k)            = u(k) + r(k-3) + r(k-4)
            C(2k)        = u(k)
            C(2k+1)   = r(k)+r(k-1)+r(k-3)+r(k-4)        for k = 0, 1, ..., 249; r(k) = 0 for k<0
     and (for termination of the coder):
            r(k)            = 0
            C(2k)        = r(k-3) + r(k-4)
            C(2k+1)   = r(k)+r(k-1)+r(k-3)+r(k-4)        for k = 250, 251, ..., 253
     The code is punctured in such a way that the following 60 coded bits:
     C(321), C(325), C(329), C(333), C(337), C(341), C(345), C(349), C(353), C(357), C(361), C(363), C(365), C(369), C(373), C(377), C(379), C(381), C(385), C(389), C(393), C(395), C(397), C(401), C(405), C(409), C(411), C(413), C(417), C(421), C(425), C(427), C(429), C(433), C(437), C(441), C(443), C(445), C(449), C(453), C(457), C(459), C(461), C(465), C(469), C(473), C(475), C(477), C(481), C(485), C(489), C(491), C(493), C(495), C(497), C(499), C(501), C(503), C(505) and C(507)
     are not transmitted. The result is a block of 448 coded and punctured bits, P(0)...P(447) which  are appended to the in-band bits in c as
            c(k+8) = P(k)      for k = 0, 1, ..., 447.
TCH/AFS10.2:
     The block of 210 bits {u(0)... u(209)} is encoded with the 1/3 rate convolutional code defined by   the following polynomials:
            G1/G3  = 1 + D + D3 + D4 / 1 + D + D2 + D3 + D4
            G2/G3 = 1 + D2 + D4 / 1 + D + D2 + D3 + D4
            G3/G3 = 1
     resulting in 642 coded bits, {C(0)... C(641)} defined by:
            r(k)            = u(k) + r(k-1) + r(k-2) + r(k-3) + r(k-4)
            C(3k)        = r(k) + r(k-1) + r(k-3) + r(k-4)
            C(3k+1)   = r(k)+r(k-2)+r(k-4)
            C(3k+2)   = u(k)                          for k = 0, 1, ..., 209
     and (for termination of the coder):
            r(k)            = 0
            C(3k)        = r(k)+r(k-1) + r(k-3) + r(k-4)
            C(3k+1)   = r(k)+r(k-2)+r(k-4)
            C(3k+2)   = r(k-1)+r(k-2)+r(k-3)+r(k-4)     for k = 210, 211, ..., 213

     C(0), C(1), C(2), C(4), C(5), C(7), C(9), C(15), C(25), C(35), C(45), C(55), C(65), C(75), C(85), C(95), C(105), C(115), C(125), C(135), C(145), C(155), C(165), C(175), C(185), C(195), C(205), C(215), C(225), C(235), C(245), C(255), C(265), C(275), C(285), C(295), C(305), C(315), C(325), C(335), C(345), C(355), C(365), C(375), C(385), C(395), C(400), C(405), C(410), C(415), C(420), C(425), C(430), C(435), C(440), C(445), C(450), C(455), C(459), C(460), C(465), C(470), C(475), C(479), C(480), C(485), C(490), C(495), C(499), C(500), C(505), C(509), C(510), C(515), C(517), C(519), C(520), C(522), C(524), C(525), C(526), C(527), C(529), C(530), C(531), C(532) and C(534)
     are not transmitted. The result is a block of 448 coded and punctured bits, P(0)...P(447) which are appended to the inband bits in c as
            c(8+k) = P(k)      for k = 0, 1, ..., 447.

The mapping is done as specified for the TCH/FS in subclause 3.1.4.
3.9.5Â Â Â Â Â Â RATSCCH
The RATSCCH message consists of 35 bits. Also delivered are two in-band channels, id0(0,1) and id1(0,1), id0 corresponding to Mode Commands or Mode Requests and id1 to Mode Indication. The general coding is as: the two in-band data channels are coded to 16 bits each, a 14-bit CRC is added to the 35 RATSCCH bits which are then coded by a rate ¼ RSC coder to 212 bits. Finally a 212 bit identification field is added thereby giving a total size of 456 bits. These 456 bits are then block interleaved in the same way as a normal speech frame.
3.9.5.1Â Â Â Â Â Â Â Â Â Â Â Coding of in-band data
The two in-band data fields, id0(0,1) and id1(0,1), are encoded, giving ic0(0..15) and ic1(0..15).
These bits are moved to the coded bits c as:
            c(k) = ic1(k)  for k = 0,1, ..., 15
            c(k+228) = ic0(k) for k = 0, 1, â¦, 15
3.9.5.2Â Â Â Â Â Â Â Â Â Â Â Parity and convolutional encoding for the RATSCCH message
a)Â Â Parity bits:
     A 14-bit CRC is used for error-detection. These 14 parity bits are generated by the cyclic generator polynomial: g(D) = D14 + D13 + D5 + D3 + D2 +1 from the 35 comfort noise parameter bits. The encoding of the cyclic code is performed in a systematic form, which means that, in GF(2), the polynomial:
d(0)D(48) + d(1)D(47) +... + d(34)D(14) + p(0)D(13) +â¦+ p(12)D+ p(13)
     where p(0), p(1) ⦠p(13) are the parity bits, when divided by g(D), yields a remainder equal to 1+ D + D2 + D3 + D4 + D5 + D6 + D7 + D8 + D9 + D10 + D11 + D12+ D13
     The information and parity bits are merged:
            u(k) = d(k)                        for k = 0, 1, â¦, 34
            u(k) = p(k-35)                 for k = 35, 36, â¦, 48
b)Â Â Convolutional encoder
     The comfort noise parameters with parity and tail bits (u(0..48)) are encoded with the ¼ rate
     convolutional code defined by the polynomials:
            G1/G3  = 1 + D + D3 + D4 / 1 + D + D2 + D3 + D4
            G2/G3 = 1 + D2 + D4 / 1 + D + D2 + D3 + D4
            G3/G3 = 1
            G3/G3 = 1
     resulting in 212 coded bits, {C(0)⦠C(211)} defined by:
            r(k)            = u(k) + r(k-1) + r(k-2) + r(k-3) + r(k-4)
            C(4k)        = r(k) + r(k-1) + r(k-3) + r(k-4)
            C(4k+1)   = r(k)+r(k-2)+r(k-4)
            C(4k+2)   = u(k)
            C(4k+3)   = u(k)                          for k = 0, 1, ..., 48; r(k) = 0 for k<0
     and (for termination of the coder):
            r(k)            = 0
            C(4k)        = r(k)+r(k-1) + r(k-3) + r(k-4)
            C(4k+1)   = r(k)+r(k-2)+r(k-4)
            C(4k+2)   = r(k-1)+r(k-2)+r(k-3)+r(k-4)
            C(4k+3)   = r(k-1)+r(k-2)+r(k-3)+r(k-4)                        for k = 49, 50, ..., 52
     This block of data is moved to the coded data (c) as:
            c(k+244) = C(k)              for k = 0, 1, ..., 211
3.9.5.3Â Â Â Â Â Â Â Â Â Â Â Identification marker
The identification marker, IM(0..211), is constructed by repeating the following 11-bit sequence: { 1, 0, 0, 1, 0, 1, 1, 0, 0, 0, 1 } 20 times and then discarding the last 8 bits. This block of data is moved to the coded data (c) as:
            c(k+16) = IM(k)             for k = 0, 1, .., 211

3.10.1Â Â Â SID_UPDATE
The speech encoder delivers 35 bits of comfort noise parameters. Also delivered is two in-band channels, id0(0,1) and id1(0,1), id0 corresponding to Mode Commands/Mode Requests and id1 to Mode Indication. The general coding is as: the two in-band data channels are coded to 16 bits each, a 14-bit CRC is added to the 35 CN bits which are then coded by a rate ¼ RSC coder to 212 bits. Finally a 212 bit identification field is added thereby giving a total size of 456 bits. These 456 bits are block interleaved over 4 bursts.
3.10.1.1Â Â Â Â Â Â Â Â Â Coding of in-band data
The two in-band data fields, id0(0,1) and id1(0,1), are encoded, giving ic0(0..15) and ic1(0..15).
The ic0 and ic1 data is moved to the coded data c as:
          c(k) = ic1(k)        for k = 0,1, .., 15
            c(k) = ic0(k-228)      for k = 228, 229, .., 243
3.10.1.2Â Â Â Â Â Â Â Â Â Parity and convolutional encoding for the comfort noise parameters
a) Â Parity bits:
     A 14-bit CRC is used for error-detection. These 14 parity bits are generated by the cyclic generator polynomial: g(D) = D14 + D13 + D5 + D3 + D2 +1 from the 35 comfort noise parameter bits. The encoding of the cyclic code is performed in a systematic form, which means that, in GF(2), the polynomial:
d(0)D(48) + d(1)D(47) +... + d(34)D(14) + p(0)D(13) +â¦+ p(12)D+ p(13)
     where p(0), p(1) ⦠p(13) are the parity
bits, when divided by g(D), yields a remainder equal to
1+ D + D2 + D3 + D4 +
D5 + D6 + D7 + D8 + D9 +
D10 + D11 + D12+ D13
     The information and parity bits are merged:
            u(k) = d(k)                        for k = 0, 1, â¦, 34
            u(k) = p(k-35)                        for k = 35, 36, â¦, 48
b) Â Convolutional encoder
     The comfort noise parameters with parity bits (u(0..48)) are encoded with the ¼ rate
     convolutional code defined by the polynomials:
            G1/G3  = 1 + D + D3 + D4 / 1 + D + D2 + D3 + D4
            G2/G3 = 1 + D2 + D4 / 1 + D + D2 + D3 + D4
            G3/G3 = 1
            G3/G3 = 1
     resulting in 212 coded bits, {C(0)⦠C(211)} defined by:
            r(k)            = u(k) + r(k-1) + r(k-2) + r(k-3) + r(k-4)
            C(4k)        = r(k) + r(k-1) + r(k-3) + r(k-4)
            C(4k+1)   = r(k)+r(k-2)+r(k-4)
            C(4k+2)   = u(k)
            C(4k+3)   = u(k)                          for k = 0, 1, ..., 48; r(k) = 0 for k<0
     and (for termination of the coder):
            r(k)            = 0
            C(4k)        = r(k)+r(k-1) + r(k-3) + r(k-4)
            C(4k+1)   = r(k)+r(k-2)+r(k-4)
            C(4k+2)   = r(k-1)+r(k-2)+r(k-3)+r(k-4)
            C(4k+3)   = r(k-1)+r(k-2)+r(k-3)+r(k-4)                        for k = 49, 50, ..., 52
     This block of data is moved to the coded data (c) as:
            c(k+244)  = C(k)                   for k = 0, 1, ..., 211
3.10.1.3Â Â Â Â Â Â Â Â Â Identification marker
The identification
marker, IM(0..211), is constructed by repeating the following 9-bit sequence:
{ 1, 0, 1, 1, 0, 0, 0, 0, 1 } 24 times and then discarding the last 4 bits.
This block of data is moved to the coded data (c) as:
     c(k+16)    = IM(k)                      for k = 0, 1, ..., 211
3.10.1.4Â Â Â Â Â Â Â Â Â Interleaving
The coded bits are reordered and interleaved according to the following rule:
i(B,j) = c(n,k) for k = 0,1,...,227
                                                 n = 0,1,...,N,N+1,...
                                                 B = B0 + 2n + b
i(B,j) = c(n,k+228)Â Â Â for k = 0,1,...,227
                                                 n = 0,1,...,N,N+1,...
                                                 B = B0 + 2n + ((b + 2) mod 4)
The values of b and j in dependence of k are given by table 4.
The result of the interleaving is a distribution of the 456 bits of a given data block, n = N, over 4 blocks using all bits for each block. The block of coded data is interleaved "block rectangular" where a new data block starts every 4th block and is distributed over 4 blocks.
3.10.1.5Â Â Â Â Â Â Â Â Â Mapping on a Burst
The mapping is given by the rule:
e(B,j) = i(B,j) and e(B,59+j) = i(B,57+j) for j = 0,1,...,56
and
e(B,57) = hl(B) and e(B,58) = hu(B)
The two bits, labelled hl(B) and hu(B) on burst number B are flags used for indication of control channel signalling. For each block not stolen for FACCH signalling purposes:
hu(B)Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = 0Â Â Â Â Â Â Â Â Â Â Â for all 4Â bursts
hl(B) Â Â = 0Â Â Â Â Â for all 4 bursts
For the use of hl(B) and hu(B) when frame is stolen for signalling purposes, see subclause 4.3.5.
3.10.2Â Â Â SID_UPDATE_INH
This special frame is used when the first 2 burst of a SID_UPDATE frame have been transmitted but the second two bursts cannot be transmitted due to a speech frame. The general coding is as: the in-band data (Note that this must be the same Mode Indication bits as id1(0,1) for the SID_UPDATE frame that is being inhibited) is encoded, a marker that is the opposite of the SID_UPDATE marker is appended and the data is interleaved in such a way that the odd bits of two bursts are filled.
3.10.2.1Â Â Â Â Â Â Â Â Â Coding of in-band data
The in-band data, Mode Indication id1(0,1), is encoded to ic1(0..15) which is moved to the coded data c as:
            c(k) = ic1(k)              for k = 0,1, .., 15
3.10.2.2Â Â Â Â Â Â Â Â Â Identification marker
The identification
marker, IM(0..211), is constructed by repeating the following 9-bit sequence:
{ 0, 1, 0, 0, 1, 1, 1, 1, 0 } 24 times and then discarding the last 4 bits.
This block of data is moved to the coded data (c) as:
     c(k+16)    = IM(k)                      for k = 0, 1, ..., 211
3.10.2.3Â Â Â Â Â Â Â Â Â Interleaving
The coded bits are reordered and interleaved according to the following rule:
     i(B,j) = c(n,k)            for             k = 1,3,5,7,...,227
                                                              n = 0,1,...,N,N+1,...
                                                              B = B0 + 2n + b - 2
The values of b and j in dependence of k are given by table 4.
The result of the interleaving is a distribution of 114 of the reordered 228 bits of a given data block, n = N, over 2 blocks using the odd numbered bits. The even numbered bits of these 2 blocks will be filled by the speech frame that following immediately after this frame.
3.10.2.4Â Â Â Â Â Â Â Â Â Mapping on a Burst
The mapping is given by the rule:
     e(B,j) = i(B,j) and e(B,59+j) = i(B,57+j) for j = 0,1,...,56
and
     e(B,57) = hl(B)
The bit labelled hl(B) on burst number B is a flag used for indication of control channel signalling. For each SID_FIRST_INH block not stolen for signalling purposes:
     hl(B) = 0  for the 2 bursts (indicating status of the odd numbered bits)
For the use of hl(B) when a SID_UPDATE_INH is stolen for signalling purposes, see subclause 4.3.5.
3.10.3Â Â Â SID_FIRST_P1
This frame type contains no source data from the speech coder. What is generated is the in-band channel and an identification marker. The in-band data id(0,1) represents Mode Indication or Mode Command/Mode Request depending on the current frame number.
3.10.3.1Â Â Â Â Â Â Â Â Â Coding of in-band data
The in-band data, id(0,1), is encoded to ic(0..15) which is moved to the coded data c as:
     c(k)           = ic (k)                       for k = 0,1, .., 15
3.10.3.2Â Â Â Â Â Â Â Â Â Identification marker
The identification
marker, IM(0..211), is constructed by repeating the following 9-bit sequence:
{ 0, 1, 0, 0, 1, 1, 1, 1, 0 } 24 times and then discarding the last 4 bits.
This block of data is moved to the coded data (c) as:
     c(k+16)    = IM(k)                      for k = 0, 1, ..., 211
3.10.3.3Â Â Â Â Â Â Â Â Â Interleaving
The interleaving is done as specified for the TCH/HS in subclause 3.2.3.
3.10.3.4Â Â Â Â Â Â Â Â Â Mapping on a Burst
The mapping is done as specified for the TCH/HS in subclause 3.2.4.
3.10.4Â Â Â SID_FIRST_P2
This frame type contains no source data from the speech coder. What is generated is the in-band channel and, derived from that, an identification marker. The in-band data id(0,1) represents Mode Indication or Mode Command/Mode Request depending on the current frame number.
3.10.4.1Â Â Â Â Â Â Â Â Â Coding of in-band data
The in-band data, id(0,1), is encoded to ic(0..15). This sequence is then repeated 7 times more, and the last 14 bits are discarded (8*16-14=114) giving the sequence ic(0..113).
This sequence is then moved to c as:
     c(2*k)      = ic(k)            for k = 0, 1, ..., 113
3.10.4.2Â Â Â Â Â Â Â Â Â Interleaving
The coded bits are reordered and interleaved according to the following rule:
     i(B,j) = c(n,k)            for             k = 0,2,4,6,...,226
                                                              n = 0,1,...,N,N+1,...
                                                              B = B0 + 2n + b
The values of b and j in dependence of k are given by table 4.
The result of the interleaving is a distribution of 114 of the reordered 228 bits of a given data block, n = N, over 2 blocks using the even numbered bits. The odd numbered bits of these 2 blocks have already been filled by the SID_FIRST_P1 frame.
3.10.4.3Â Â Â Â Â Â Â Â Â Mapping on a Burst
The mapping is given by the rule:
     e(B,j) = i(B,j) and e(B,59+j) = i(B,57+j) for j = 0,1,...,56
and
     e(B,58) = hu(B)
The bit labelled hu(B) on burst number B is a flag used for indication of control channel signalling. For each SID_FIRST_P2 block not stolen for signalling purposes:
     hu(B) = 0 for the 2 bursts (indicating status of the even numbered bits)
For the use of hu(B) when a SID_FIRST_P2 is stolen for signalling purposes, see subclause 4.3.5.
3.10.5Â Â Â SID_FIRST_INH
This special frame is used when the first 2 burst of a SID_FIRST_P1 frame have been transmitted but the second two bursts cannot be transmitted due to a SPEECH frame. The general coding is as: the in-band data (Note that this must be the same data as for the SID_FIRST_P1 frame that is being inhibited) is encoded, a marker that is the opposite of the SID_FIRST_P1 marker is appended and the data is interleaved in such a way that the odd bits of two bursts are filled.
3.10.5.1Â Â Â Â Â Â Â Â Â Coding of in-band data
The coding of the in-band data is done as specified for the SID_FIRST_P1 frame in subclause 3.10.3.1.
3.10.5.2Â Â Â Â Â Â Â Â Â Identification marker
The identification
marker, IM(0..211), is constructed by repeating the following 9-bit sequence:
{ 1, 0, 1, 1, 0, 0, 0, 0, 1 } 24 times and then discarding the last 4 bits.
This block of data is moved to the coded data (c) as:
            c(k+16)    = IM(k)                      for k = 0, 1, ..., 211
3.10.5.3Â Â Â Â Â Â Â Â Â Interleaving

The mapping is done as specified for the SID_UPDATE_INH in subclause 3.10.2.4.
3.10.6Â Â Â ONSET
Onset frames are used to preset the interleaver buffer after a period of no speech activity in DTX mode. This frame type contains no source data from the speech coder. What is transmitted is the in-band channel signalling the Mode Indication for the speech frame following the onset marker.
3.10.6.1Â Â Â Â Â Â Â Â Â Coding of in-band data
The in-band data, Mode Indication id1(0,1), will be encoded to ic1(0..15). This sequence is then repeated 7 times more, and the last 14 bits are discarded (8*16-14=114) giving the sequence ic1(0..113).
This sequence is then moved to c as:
     c(2*k+1)  = ic1(k)                for k = 0, 1, ..., 113
3.10.6.2Â Â Â Â Â Â Â Â Â Interleaving
The interleaving is done as specified for the SID_UPDATE_INH in subclause 3.10.2.3.
3.10.6.3Â Â Â Â Â Â Â Â Â Mapping on a Burst
The mapping is done as specified for the SID_UPDATE_INH in subclause 3.10.2.4.
3.10.7Â Â Â SPEECH
The speech coder delivers to the channel encoder a sequence of blocks of data. One block of data corresponds to one speech frame and the block length is different in each of the six channel codec modes. Adjoining each block of data is information of the channel codec mode to use when encoding the block Also delivered is the in-band data id(0,1) representing Mode Indication or Mode Command/Mode Request depending on the current frame number.
3.10.7.1Â Â Â Â Â Â Â Â Â Coding of the in-band data
The two bits to be in-band encoded, id(0,1), are encoded into ic(0..3).
The encoded in-band data (4 bits) are then moved to c(k) as:
     c(k) = ic(k)                 for k = 0, 1, â¦, 3
3.10.7.2Â Â Â Â Â Â Â Â Â Ordering according to subjective importance
The bits delivered by the speech encoder, {s(1),s(2),...,s(Ks)}, are rearranged according to subjective importance before channel coding, Tables 9, 10, 11, 12, 13, 14 define the correct rearrangement for the speech codec modes 7.95 kbit/s, 7.40 kbit/s, 6.70 kbit/s, 5.90 kbit/s, 5.15 kbit/s and 4.75 kbit/s, respectively. In the tables speech codec parameters are numbered in the order they are delivered by the corresponding speech encoder according to 3GPP TS 26.090 and the rearranged bits are labelled {d(0),d(1),...,d(Kd-1)}, defined in the order of decreasing importance. Index Kd refers to the number of bits delivered by the speech encoder, see below:

The ordering algorithm is in pseudo code as:
     for j = 0 to Kd-1  d(j) := s(table(j)+1);       where table(j) is read line by line left to right
The rearranged bits are further divided into three different classes to perform unequal error protection for different bits according to subjective importance.
The protection classes are:
            1a -    Data protected with the CRC
and the convolution code.
     1b -    Data protected with the convolution code.
            2   -    Data sent without protection.
The number of class 1 (sum of class 1a and 1b), class 1a, class 1b and class 2 bits for each codec mode is shown below:
|
Codec mode
|
Number of speech bits delivered per block |
Number of class 1 bits per block |
Number of class 1a bits per block |
Number of  class 1b bits per block |
Number of class 2 bits per block |

A 6-bit CRC is used for error-detection.
These 6 parity bits are generated by the cyclic generator polynomial:
g(D) = D6 + D5 + D3 + D2 + D1
+ 1 from the first Kd1a bits of class 1, where Kd1a
refers to number of bits in protection class 1a. The value of Kd1a for
each codec mode is shown above.
The encoding of the cyclic code is
performed in a systematic form, which means that, in GF(2), the polynomial:
d(0)D(Kd1a+5)Â +
d(1)D(Kd1a+4) +... + d(Kd1a-1)D(6) + p(0)D(5) +â¦+ p(4)D+ p(5)
where p(0), p(1) ⦠p(5) are the parity bits, when divided by g(D), yields a remainder equal to:
            1+ D + D2 + D3 + D4 + D5.
The information and parity bits are merged:
            u(k) = d(k)                        for k = 0, 1, â¦, Kd1a-1
            u(k) = p(k-Kd1a)              for k = Kd1a, Kd1a+1, â¦, Kd1a+5
            u(k) = d(k-6)                    for k = Kd1a+6, Kd1a+7, â¦, Ku-1
Thus, after the first encoding step u(k) will be defined by the following contents for each codec mode:
TCH/AHS7.95:
            u(k) = d(k)                        for k = 0, 1, â¦, 66
            u(k) = p(k-67)                  for k = 67, 68, â¦, 72
            u(k) = d(k-6)                    for k = 73, 74, â¦, 128

            u(k) = p(k-61)                  for k = 61, 62, â¦, 66
            u(k) = d(k-6)                    for k = 67, 68, â¦, 125

            u(k) = d(k)                        for k = 0, 1, â¦, 54
            u(k) = p(k-55)                  for k = 55, 56, â¦, 60
            u(k) = d(k-6)                    for k = 61, 62, â¦, 107
TCH/AHS5.15:
            u(k) = d(k)                        for k = 0, 1, â¦, 48
            u(k) = p(k-49)                  for k = 49, 50, â¦, 54
            u(k) = d(k-6)                    for k = 55, 56, â¦, 96
TCH/AHS4.75:
            u(k) = d(k)                        for k = 0, 1, ..., 38
            u(k) = p(k-39)                  for k = 39, 40, ..., 44

The in-band data, ic(0,1), is encoded to ic(0..15) which is moved to the coded data c as:
     c(k)           = ic (k)                       for k = 0,1, .., 15
3.10.8.2Â Â Â Â Â Â Â Â Â Identification marker

constructed by repeating the following 11-bit sequence:
{ 1, 0, 0, 1, 0, 1, 1, 0, 0, 0, 1 } 20 times and then discarding the last 8
bits. This block of data is moved to the coded data (c) as:
            c(k+16) = IM(k)             for k = 0, 1, .., 211

3.10.9Â Â Â RATSCCH_DATA
This frame contains the RATSCCH data and an inband channel. The RATSCCH data consists of 35 bits. The in-band data id(0,1) represents Mode Indication or Mode Command/Mode Request depending on the current frame number.
3.10.9.1Â Â Â Â Â Â Â Â Â Coding of in-band data
The in-band data, ic(0,1), is encoded to ic(0..15) which is moved to the coded data c as:
     c(k)           = ic (k)                       for k = 0,1, .., 15
3.10.9.2Â Â Â Â Â Â Â Â Â Parity and convolutional encoding for the RATSCCH message
a) Â Parity bits:
     A 14-bit CRC is used for error-detection. These 14 parity bits are generated by the cyclic generator polynomial: g(D) = D14 + D13 + D5 + D3 + D2 +1 from the 35 comfort noise parameter bits. The encoding of the cyclic code is performed in a systematic form, which means that, in GF(2), the polynomial:
d(0)D(48) + d(1)D(47) +... + d(34)D(14) + p(0)D(13) +â¦+ p(12)D+ p(13)
     where p(0), p(1) ⦠p(13) are the parity bits, when divided by g(D), yields a remainder equal to 1+ D + D2 + D3 + D4 + D5 + D6 + D7 + D8 + D9 + D10 + D11 + D12+ D13
The information and parity bits are merged:
     u(k) = d(k)                        for k = 0, 1, â¦, 34
     u(k) = p(k-35)                 for k = 35, 36, â¦, 48
b) Â Convolutional encoder
     The comfort noise parameters with parity and tail bits (u(0..48)) are encoded with the ¼ rate
     convolutional code defined by the polynomials:
            G1/G3  = 1 + D + D3 + D4 / 1 + D + D2 + D3 + D4
            G2/G3 = 1 + D2 + D4 / 1 + D + D2 + D3 + D4
            G3/G3 = 1
            G3/G3 = 1
     resulting in 212 coded bits, {C(0)⦠C(211)} defined by:
            r(k)            = u(k) + r(k-1) + r(k-2) + r(k-3) + r(k-4)
            C(4k)        = r(k) + r(k-1) + r(k-3) + r(k-4)
            C(4k+1)   = r(k)+r(k-2)+r(k-4)
            C(4k+2)   = u(k)
            C(4k+3)   = u(k)                          for k = 0, 1, ..., 48; r(k) = 0 for k<0
     and (for termination of the coder):
            r(k)            = 0
            C(4k)        = r(k)+r(k-1) + r(k-3) + r(k-4)
            C(4k+1)   = r(k)+r(k-2)+r(k-4)
            C(4k+2)   = r(k-1)+r(k-2)+r(k-3)+r(k-4)
            C(4k+3)   = r(k-1)+r(k-2)+r(k-3)+r(k-4)                        for k = 49, 50, ..., 52
     This block of data is moved to the coded data (c) as:
            c(k+16) = C(k)                for k = 0, 1, ..., 211

3.11Â Â Â Â Â Data channel for ECSD at full rate, 29.0 kbit/s radio interface rate (28.8 kbit/s services (E-TCH/F28.8))
The definition of a 28.8 kbit/s radio interface rate data flow for data services is given in 3GPP TS 44.021.
3.11.1Â Â Â Interface with user unit
The user unit delivers to the encoder a bit stream organized in blocks of 580 information bits (data frames) every 20 ms.
3.11.2Â Â Â Block code
3.11.2.1Â Â Â Â Â Â Â Â Â Repetition bits
To match to RS alphabet 4 extra data bits are added to the end of each block of 580 bits: d(k)=0, k=580,â¦583.
3.11.2.2Â Â Â Â Â Â Â Â Â Reed Solomon encoder
The block of 584 information bits is encoded by shortened systematic Reed Solomon (RS) code over Galois field GF(28). The Galois field GF(28) is built as an extension of GF(2). The characteristic of GF(28) is equal to 2.
The code used is systematic RS8 (85,73), which is shortened systematic RS8(255,243) code over GF(28) with the primitive polynomial p(x)=x8+x4+x3+x2+1. The primitive element a is the root of the primitive polynomial, i.e.
a8 = a4 + a3 + a2 + 1.
Generator polynomial for RS8(255,243) code is:
g(x)=
; thatÂ
results in symmetrical form for the generator polynomial with coefficients
given in decimal notation Â
g(x)= x12 +18x11 + 157x10 + 162x9 + 134x8 + 157x7 + 253x6 + 157x5 + 134x4 + 162x3 + 157x2 + 18x + 1
where binary presentation of polynomial coefficients in GF(256) is {a7, a6, a5, a4, a3, a2, a, 1}.
Specifically, decimal, power and polynomial presentations for the generator polynomial coefficients are the following:
x12:Â 1
x11:Â 18 = a224 =Â a4 + a
x10: 157Â = a32 =Â a7 + a4 + a3 + a2 + 1
x9:Â 162 = a209 =Â a7 + a5 + a
x8:Â 134 = a99 = a7 + a2 + a
x7:Â 157 = a32 = a7 + a4 + a3 + a2 + 1
x6:Â 253 = a80 = a7 + a6 + a5 + a4 + a3 + a2 + 1
x5:Â 157 = a32 = a7 + a4 + a3 + a2 + 1
x4:Â 134 = a99 = a7 + a2 + a
x3:Â 162 =a209 =Â a7 + a5 +a
x2:Â 157 =a32 = a7 + a4 + a3 + a2 + 1
x1:Â 18 = a224 = a4 +Â a
x0:Â 1= a255 = 1
The RS encoding is performed in the following three steps:
a)Â Â Bit to symbol conversion
The information bits {d(0),d(1),â¦,d(583)} are converted into 73 information 8-bit symbols {D(0),â¦,D(72)} as the following:
     D(k) = 128d(8k+7) +
64d(8k+6) + 32d(8k+5) + 16d(8k+4) + 8d(8k+3) + 4d(8k+2) + 2d(8k+1) + d(8k)
for k = 0,1,...,72
     Resulting 8-bit symbols are presented as
     D(k) = {d(8k+7), d(8k+6), d(8k+5), d(8k+4), d(8k+3), d(8k+2), d(8k+1), d(8k)}       for k = 0,1,...,72
     where d(8k+7),â¦,d(8k) are ordered from the most significant bit (MSB) to the less significant bit (LSB).
     The polynomial representation of a single information symbol over GF(28) in terms of a is given by
Da(k) = a7d(8k+7) + a6d(8k+6) + a5d(8k+5) + a4d(8k+4) + a3d(8k+3) + a2d(8k+2) + ad(8k+1) + d(8k)
b)Â Â Encoding
     The information symbols D(0)â¦D(72) are encoded by shortened systematic RS8(85,73) code with output symbols    U(0)â¦U(84) ordered as
     U(k)=D(k) for k=0,1,..72; U(k)=R(k) for k=73,74,â¦,84;
     where R(k) are parity check symbols added by RS8(85,73) encoder.
     Information symbols are ordered in the descending polynomial order such that Da (72) corresponds to the lowest  Â
     degree term of D(x) = Da(72) + Da (71)x + â¦+ Da (1)x71 + Da (0)x72, where D(x) is the polynomial representation of
     information symbols {D(0),D(1),â¦,D(72)} over Galois field .
     Parity check symbols in polynomial representation over Galois field are ordered in the descending polynomial order such that Ra(84) corresponds to the lowest degree of R(x)=Ra(84) + Ra(83)x + ⦠+ Ra(74)x10 + Ra(73)x11. The parity check symbols are calculated as R(x) = remainder [x12 D(x)/g(x)], and U(x) = R(x) + x12 D(x), i.e.,
     Ua(k) = Da(k) for k=0,1,..72; Ua(k) = Ra(k) for k=73,74,â¦,84.
     The encoding operation with the shortened RS8(85,73) code may be presented as the following:
-Â Â Â Â Expanding 73 information symbols to the block of 243 symbols by adding 170 dump (zero) symbols
-Â Â Â Â Encoding 243 symbols by systematic RS8(255,243) encoder with outer block of 255 symbols
-Â Â Â Â Removing 170 dump symbols, resulting in the output block of 85 symbols.
c)Â Â Symbol to bit conversionÂ
     The output symbols {Ua(0),â¦,Ua(84)}are converted back into symbols {U(0),â¦,U(84)} and then back into binary form with LSB coming out first, resulting in the block of 680 bits {u(0),â¦u(679)}.
3.11.3Â Â Â Convolutional encoder
3.11.3.1Â Â Â Â Â Â Â Â Â Tailing bits for a data frame
Before convolutional encoding 6 tail bits {u(k)=0, k=680,â¦685}are added to the end of each data block .
3.11.3.2Â Â Â Â Â Â Â Â Â Convolutional encoding for a data frame
This block of 686 bits {u(0),...,u(685)} is encoded with the ½ rate convolutional code defined by the following polynomials:
     G4 = 1 + D2 + D3 + D5 + D6
     G7 = 1 + D + D2 + D3 + D6
resulting in 1372 coded bits {c(0), c(1),..., c(1371)} with
c(2k)= u(k)+u(kâ2)+u(kâ3)+ u(kâ5)+u(kâ6);
c(2k+1)= u(k)+u(kâ1)+ u(kâ2)+ u(kâ3)+ u(kâ6)Â for k = 0,1,...,685;Â u(k) = 0 for k<0
The code is punctured in such a way that the following 4 coded bits:
c(363), c(723), c(1083) and c(1299) are not transmitted.
The result is a block of 1368 coded bits, {c(0),c(1),..., c(1367)}.
3.11.4Â Â Â Interleaving
The interleaving scheme is presented below.
The coded bits are reordered and interleaved according to the following rule:
            i(B,j) = c(n,k),     for k = 0,1,...,1367
                  n = 0,1,...,N,N+1,â¦
                  B = B0 + 4n + (k mod 19) + (k div 342)
            j  = (k mod 19) + 19(k mod 18)
The result of the interleaving is a distribution of the reordered 342 bit of a given data block, n = N, over 19 blocks, 18 bits equally distributed in each block, in a diagonal way over consecutive blocks.
Or in other words the interleaving is a distribution of the encoded, reordered 1368 bits from four given input data blocks, which taken together give n = N, over 22 bursts, 18 bits equally distributed in the first and 22nd bursts, 36 bits distributed in the second and 21st bursts, 54 bits distributed in the third and 20th bursts and 72 bits distributed in the other 16 bursts.
The block of coded data is interleaved "diagonal", where a new block of coded data starts with every fourth burst and is distributed over 22 bursts.Â
3.11.5Â Â Â Mapping on a Burst
Before mapping on a burst the interleaved bits {i(0)â¦i(1367)} are converted into 3-bit symbols {I(0),I(1), â¦,I(455)} according to Table 1 in 3GPP TS 45.004, the symbol I(k) depends on i(3k+2), i(3k+1) and i(3k) for k=0,1,â¦,455.
The E-IACCH message delivered to the encoder on every 20ms has a fixed size of 3 information bits {im(0), im(1), im(2)}. The contents of the bits are defined in 3GPP TS 45.008 for both uplink and downlink.
The E-IACCH information bits
{im(n,0),im(n,1),im(n,2)} are coded into 24 bits
ib(B,k), B0 + 4n £ B < B0 + 4n + 4, k = 0,1,...5
according to the following table:
|
im(n,0),im(n,1),im(n,2) |
ib(B0+4n,0),...,ib(B0+4n,5),..., ib(B0+4n+3,0),...,ib(B0+4n+3,5) |

Before mapping on a burst the E-IACCH bits
{ib(B,0)â¦ib(B,5)} are converted into 3-bit symbols
{HL(B),HU(B)} according to Table 1 in 3GPP TS 45.004. The symbol HL(B) depends
on ib(B,2), ib(B,1) and ib(B,0) and ,
the symbol HU(B) on ib(B,5), ib(B,4) and ib(B,3).
The mapping is given by the rule:
E(B,j)    = I(B,j)  and    E(B,59+j) = I(B,57+j)          for j = 0,1,...,56
and
E(B,57) = HL(B)  and  E(B,58) = HU(B).
The two symbols, labelled HL(B) and HU(B) on burst number B are flags used for E-IACCH.

The definition of a 32.0 kbit/s radio interface rate data flow for data services is given in 3GPP TS 44.021.
3.12.1Â Â Â Interface with user unit
The user unit delivers to the encoder a bit stream organized in blocks of 640 information bits (data frames) every 20 ms.
3.12.2Â Â Â Void
3.12.3Â Â Â Convolutional encoder
3.12.3.1Â Â Â Â Â Â Â Â Â Tailing bits for a data frame
Before convolutional encoding 6 tail bits {d(k)=0, k=640,â¦,645} are added to the end of each data block.
3.12.3.2Â Â Â Â Â Â Â Â Â Convolutional encoding for a data frame
This block of 646 bits {d(0),...,d(645)} is encoded with the 1/3 rate convolutional code (the same code as for MCS-1) defined by the following polynomials:
     G4 = 1 + D2 + D3 + D5 + D6
     G7 = 1 + D + D2 + D3 + D6
G5 = 1 + D + D4 + D6
resulting in 1938 coded bits {c(0), c(1),..., c(1937)} with
c(3k) = d(k) + d(k-2) + d(k-3) + d(k-5) + d(k-6) ;
c(3k+1) = d(k) + d(k-1) + d(k-2) + d(k-3) + d(k-6) ;
c(3k+2) = d(k) + d(k-1) + d(k-4) + d(k-6) ;

The code is punctured using the rate matching algorithm of clause 6.2.3, such that the following 546 coded bits:
c(0), c(3), c(7), c(10), c(14), c(17), c(21), c(24), c(28), c(31), c(35), c(39), c(42), c(46), c(49), c(53), c(56), c(60), c(63), c(67), c(70), c(74), c(78), c(81), c(85), c(88), c(92), c(95), c(99), c(102), c(106), c(110), c(113), c(117), c(120), c(124), c(127), c(131), c(134), c(138), c(141), c(145), c(149), c(152), c(156), c(159), c(163), c(166), c(170), c(173), c(177), c(181), c(184), c(188), c(191), c(195), c(198), c(202), c(205), c(209), c(212), c(216), c(220), c(223), c(227), c(230), c(234), c(237), c(241), c(244), c(248), c(252), c(255), c(259), c(262), c(266), c(269), c(273), c(276), c(280), c(283), c(287), c(291), c(294), c(298), c(301), c(305), c(308), c(312), c(315), c(319), c(323), c(326), c(330), c(333), c(337), c(340), c(344), c(347), c(351), c(354), c(358), c(362), c(365), c(369), c(372), c(376), c(379), c(383), c(386), c(390), c(393), c(397), c(401), c(404), c(408), c(411), c(415), c(418), c(422), c(425), c(429), c(433), c(436), c(440), c(443), c(447), c(450), c(454), c(457), c(461), c(464), c(468), c(472), c(475), c(479), c(482), c(486), c(489), c(493), c(496), c(500), c(504), c(507), c(511), c(514), c(518), c(521), c(525), c(528), c(532), c(535), c(539), c(543), c(546), c(550), c(553), c(557), c(560), c(564), c(567), c(571), c(575), c(578), c(582), c(585), c(589), c(592), c(596), c(599), c(603), c(606), c(610), c(614), c(617), c(621), c(624), c(628), c(631), c(635), c(638), c(642), c(646), c(649), c(653), c(656), c(660), c(663), c(667), c(670), c(674), c(677), c(681), c(685), c(688), c(692), c(695), c(699), c(702), c(706), c(709), c(713), c(716), c(720), c(724), c(727), c(731), c(734), c(738), c(741), c(745), c(748), c(752), c(756), c(759), c(763), c(766), c(770), c(773), c(777), c(780), c(784), c(787), c(791), c(795), c(798), c(802), c(805), c(809), c(812), c(816), c(819), c(823), c(827), c(830), c(834), c(837), c(841), c(844), c(848), c(851), c(855), c(858), c(862), c(866), c(869), c(873), c(876), c(880), c(883), c(887), c(890), c(894), c(898), c(901), c(905), c(908), c(912), c(915), c(919), c(922), c(926), c(929), c(933), c(937), c(940), c(944), c(947), c(951), c(954), c(958), c(961), c(965), c(969), c(972), c(976), c(979), c(983), c(986), c(990), c(993), c(997), c(1000), c(1004), c(1008), c(1011), c(1015), c(1018), c(1022), c(1025), c(1029), c(1032), c(1036), c(1039), c(1043), c(1047), c(1050), c(1054), c(1057), c(1061), c(1064), c(1068), c(1071), c(1075), c(1079), c(1082), c(1086), c(1089), c(1093), c(1096), c(1100), c(1103), c(1107), c(1110), c(1114), c(1118), c(1121), c(1125), c(1128), c(1132), c(1135), c(1139), c(1142), c(1146), c(1150), c(1153), c(1157), c(1160), c(1164), c(1167), c(1171), c(1174), c(1178), c(1181), c(1185), c(1189), c(1192), c(1196), c(1199), c(1203), c(1206), c(1210), c(1213), c(1217), c(1221), c(1224), c(1228), c(1231), c(1235), c(1238), c(1242), c(1245), c(1249), c(1252), c(1256), c(1260), c(1263), c(1267), c(1270), c(1274), c(1277), c(1281), c(1284), c(1288), c(1292), c(1295), c(1299), c(1302), c(1306), c(1309), c(1313), c(1316), c(1320), c(1323), c(1327), c(1331), c(1334), c(1338), c(1341), c(1345), c(1348), c(1352), c(1355), c(1359), c(1362), c(1366), c(1370), c(1373), c(1377), c(1380), c(1384), c(1387), c(1391), c(1394), c(1398), c(1402), c(1405), c(1409), c(1412), c(1416), c(1419), c(1423), c(1426), c(1430), c(1433), c(1437), c(1441), c(1444), c(1448), c(1451), c(1455), c(1458), c(1462), c(1465), c(1469), c(1473), c(1476), c(1480), c(1483), c(1487), c(1490), c(1494), c(1497), c(1501), c(1504), c(1508), c(1512), c(1515), c(1519), c(1522), c(1526), c(1529), c(1533), c(1536), c(1540), c(1544), c(1547), c(1551), c(1554), c(1558), c(1561), c(1565), c(1568), c(1572), c(1575), c(1579), c(1583), c(1586), c(1590), c(1593), c(1597), c(1600), c(1604), c(1607), c(1611), c(1615), c(1618), c(1622), c(1625), c(1629), c(1632), c(1636), c(1639), c(1643), c(1646), c(1650), c(1654), c(1657), c(1661), c(1664), c(1668), c(1671), c(1675), c(1678), c(1682), c(1685), c(1689), c(1693), c(1696), c(1700), c(1703), c(1707), c(1710), c(1714), c(1717), c(1721), c(1725), c(1728), c(1732), c(1735), c(1739), c(1742), c(1746), c(1749), c(1753), c(1756), c(1760), c(1764), c(1767), c(1771), c(1774), c(1778), c(1781), c(1785), c(1788), c(1792), c(1796), c(1799), c(1803), c(1806), c(1810), c(1813), c(1817), c(1820), c(1824), c(1827), c(1831), c(1835), c(1838), c(1842), c(1845), c(1849), c(1852), c(1856), c(1859), c(1863), c(1867), c(1870), c(1874), c(1877), c(1881), c(1884), c(1888), c(1891), c(1895), c(1898), c(1902), c(1906), c(1909), c(1913), c(1916), c(1920), c(1923), c(1927), c(1930), c(1934)
are not transmitted.
The result is a block of 1392 coded bits, {c(0),c(1),..., c(1391)}.
3.12.4Â Â Â Interleaving
The coded bits are reordered and interleaved according to the following rule:
     i(B,j) = c(n,k),     for k = 0,1,...,1391
     n = 0,1,...,N,N+1,â¦
     B = B0 + 4n + (k mod 12)
     j = 3*[(49*(k+int(k/348)) mod 116) + int[(k mod 12)/4]
The result of the interleaving is a distribution of the reordered 348 bits of a given data block, n = N, over 12 blocks, 29 bits equally distributed in each block. The block of coded data is interleaved "diagonal", where a new block of coded data starts with every fourth burst and is distributed over 12 bursts.
3.12.5Â Â Â Mapping on a Burst
The mapping is given by the rule:
e(B,j) = i(B,j)     for j = 0,1,â¦,347
NOTE:Â Â Â Â Â No stealing flags are used.
3.13Â Â Â Â Â Data channel for ECSD at full rate, 43.5 kbit/s radio interface rate (43.2 kbit/s services (E-TCH/F43.2))
The definition of a 43.5 kbit/s radio interface rate data flow for data services is given in 3GPP TS 44.021.
3.13.1Â Â Â Interface with user unit
The user unit delivers to the encoder a bit stream organized in blocks of 870 information bits (data frames) every 20 ms.
3.13.2Â Â Â Convolutional encoder
3.13.2.1Â Â Â Â Â Â Â Â Â Tailing bits for a data frame
Before convolutional encoding 6 tail bits {d(k)=0, k=870,â¦875} are added to the end of each data block .
3.13.2.2Â Â Â Â Â Â Â Â Â Convolutional encoding for a data frame
This block of 876 bits {d(0),...,d(875)} is encoded with the ½ rate convolutional code defined by the following polynomials:
     G4 = 1 + D2 + D3 + D5 + D6
     G7 = 1 + D + D2 + D3 + D6
resulting in 1752 coded bits {c(0), c(1),..., c(1751)} with
c(2k)= d(k)+d(kâ2)+d(kâ3)+ d(kâ5)+d(kâ6);
c(2k+1)= d(k)+d(kâ1)+ d(kâ2)+ d(kâ3)+ d(kâ6)Â for k = 0,1,...,875;Â u(k) = 0 for k<0
The code is punctured in such a way that the following 384 coded bits:
c(2+8(k-1)) for k=1:219; c(4+16(k-1)) for k=1:110;Â c(6+32(k-1)) for k=1:55
are not transmitted.
The result is a block of 1368 coded bits, {c(0),c(1),..., c(1367)}.
3.13.3Â Â Â Interleaving
The interleaving is done as specified for E-TCH/F28.8 in subclause 3.11.4.
3.13.4Â Â Â Mapping on a Burst
The mapping is done as specified for E-TCH/F28.8 in subclause 3.11.5.
3.14Â Â Â Â Â Wideband Adaptive multi rate speech channel at full rate (TCH/WFS)
This section describes the coding for the different frame formats used for TCH/WFS. The formats used are (in the order they are described):
SID_UPDATEÂ Â Â Â Â Used to convey comfort noise parameters during DTX
SID_FIRSTÂ Â Â Â Â Â Â Â Â Marker to define end of speech, start of DTX
ONSETÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Used to signal the Codec mode for the first speech frame after DTX
SPEECHÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Speech frames
RATSCCHÂ Â Â Â Â Â Â Â Â Â Frames used to convey RATSCCH messages
In this chapter, sub chapters 3.14.1 to 3.14.4 describe the channel coding for the different formats listed above.
Common to all the formats is that in-band information is conveyed, the coding for the in-band channel is described in the table below.

3.14.1Â Â Â SID_UPDATE
The SID_UPDATE frames are handled as specified for the TCH/AFS in subclause 3.9.1.
3.14.2Â Â Â SID_FIRST
The SID_FIRST frames are handled as specified for the TCH/AFS in subclause 3.9.2.
3.14.3Â Â Â ONSET
The Onset frames are handled as specified for the TCH/AFS in subclause 3.9.3.
3.14.4Â Â Â SPEECH
The speech coder delivers to the channel encoder a sequence of blocks of data. One block of data corresponds to one speech frame and the block length is different in each of the seven channel codec modes. Adjoining each block of data is information of the channel codec mode to use when encoding the block. Also delivered is the in-band data id(0,1) representing Mode Indication or Mode Command/Mode Request depending on the current frame number.
3.14.4.1Â Â Â Â Â Â Â Â Â Coding of the in-band data
The two input in-band bits (id(0,1)) are coded to eight coded in-band bits (ic(0..7)).
The encoded in-band bits are moved to the coded bits, c, as
     c(k) = ic(k)          for k = 0, 1, ..., 7.
3.14.4.2Â Â Â Â Â Â Â Â Â Ordering according to subjective importance
The bits delivered by the speech encoder, {s(1),s(2),...,s(Ks)}, are rearranged according to subjective importance before channel coding. Tables 16 to 18 define the correct rearrangement for the speech codec modes 12.65 kbit/s, 8.85 kbit/s and 6.60 kbit/s, respectively. In the tables speech codec parameters are numbered in the order they are delivered by the corresponding speech encoder according to 3GPP TS 26.190 and the rearranged bits are labelled {d(0),d(1),...,d(Kd-1)}, defined in the order of decreasing importance. Index Kd refers to the number of bits delivered by the speech encoder, see below:

The ordering algorithm is in pseudo code as:
     for j = 0 to Kd-1  d(j) := s(table(j)+1);             where table(j) is read line by line left to right
The rearranged bits are further divided into two different classes to perform unequal error protection for different bits according to subjective importance.
The protection classes are:
            1a -    Data protected with the CRC
and the convolution code.
     1b -    Data protected with the convolution code.
The number of class 1 (sum of class 1a and 1b), class 1a and class 1b bits for each codec mode is shown below:

A 8-bit or 6-bit CRC is used for error-detection. These parity bits are generated by the cyclic generator polynomial: g8(D) = D8Â + D4Â + D3Â + D2Â + 1 or g6(D) = D6 + D5 + D3 + D2 + D1 + 1 respectively from the first Kd1a bits of class 1, where Kd1a refers to number of bits in protection class 1a as shown above for each codec mode. The encoding of the cyclic code is performed in a systematic form, which means that, in GF(2), the polynomial:
d(0)D(Kd1a+n-1) + d(1)D(Kd1a+n-2) +... + d(Kd1a-1)D(n) + p(0)D(n-1) +â¦+ p(n-2)D+ p(n-1)
where p(0), p(1) ⦠p(n) are the parity bits (n=8 or 6), when divided by g8(D) or g6(D), yields a remainder equal to:
1+ D + ⦠+ Dn-1.
The information and parity bits are merged:
u(k) = d(k)                        for k = 0, 1, â¦, Kd1a-1
u(k) = p(k-Kd1a)             for k = Kd1a, Kd1a+1, â¦, Kd1a+ (nâ1)
u(k) = d(k-n)                    for k = Kd1a+n, Kd1a+n+1, â¦, Ku-1
Thus, after the first encoding step u(k) will be defined by the following contents for each codec mode:
TCH/WFS12.65:
            u(k) = d(k)                        for k = 0, 1, ..., 71
            u(k) = p(k-72)                  for k = 72, 73, â¦, 77
            u(k) = d(k-6)                    for k = 78, 79, â¦, 258
TCH/WFS8.85:
            u(k) = d(k)                        for k = 0, 1, â¦, 63
            u(k) = p(k-64)                  for k = 64, 65, â¦, 69
            u(k) = d(k-6)                    for k = 70, 71, â¦, 182
TCH/WFS6.60:
            u(k) = d(k)                        for k = 0, 1, ..., 53
            u(k) = p(k-54)                  for k = 54, 55, ..., 61
            u(k) = d(k-8)                    for k = 62, 63, ..., 139
3.14.4.4Â Â Â Â Â Â Â Â Â Convolutional encoder
The bits from the first encoding step (u(k)) are encoded with the recursive systematic convolutional codes as summarised below. The number of output bits after puncturing is 448 for all codec modes.

Below the coding for each codec mode is specified in detail. The puncturing for each mode is designed to give an even protection of the class 1A bits while the protection within class 1B is not equal to reflect the individual error sensitivity of the class 1B bits.
TCH/WFS12.65:
     The block of 259 bits {u(0)⦠u(258)} is encoded with the ½ rate convolutional code defined by    the following polynomials:
            G0/G0 = 1
            G1/G0 = 1 + D + D3+ D4 / 1 + D3 + D4
     resulting in 518 coded bits, {C(0)⦠C(517)} defined by:
            r(k)            = u(k) + r(k-3) + r(k-4)
            C(2k)        = u(k)
            C(2k+1)   = r(k)+r(k-1)+r(k-3)+r(k-4)               for k = 0, 1, ..., 258; r(k) = 0 for k<0
     and (for termination of the coder):
            r(k)            = 0
            C(2k)        = r(k-3) + r(k-4)

3.15.1 Â Â Â SID_UPDATE
The speech encoder delivers 35 bits of comfort noise parameters. Also delivered is two in-band channels, id0(0,1) and id1(0,1), id0 corresponding to Mode Commands/Mode Requests and id1 to Mode Indication. The general coding is as: the two in-band data channels are coded to 16 bits each, a 14-bit CRC is added to the 35 CN bits which are then coded by a rate ¼ RSC coder to 212 bits. A 212 bit identification field is added thereby giving a total size of 456 bits. Finally each bit is repeated 3 times and then converted into 3-bit symbols giving a total size of 456 symbols. These 456 symbols are block interleaved over 4 bursts.

The rearranged bits are further divided into three different classes to perform unequal error protection for different bits according to subjective importance.
The protection classes are:
            1a -    Data protected with the CRC
and the convolution code.
     1b -    Data protected with the convolution code.
The number of class 1 (sum of class 1a and 1b), class 1a and class 1b bits for each codec mode is shown below:

A 6-bit CRC is used for error-detection. These 6 parity bits are generated by the cyclic generator polynomial: g(D) = D6 + D5 + D3 + D2 + D1 + 1 from the first Kd1a bits of class 1, where Kd1a refers to number of bits in protection class 1a as shown above for each codec mode. The encoding of the cyclic code is performed in a systematic form, which means that, in GF(2), the polynomial:
d(0)D(Kd1a+5) + d(1)D(Kd1a+4) +... + d(Kd1a-1)D(6) + p(0)D(5) +â¦+ p(4)D+ p(5)
where p(0), p(1) ⦠p(5) are the parity bits, when divided by g(D), yields a remainder equal to:
1+ D + D2 + D3 + D4 + D5.
The information and parity bits are merged:
u(k) = d(k)                        for k = 0, 1, â¦, Kd1a-1
u(k) = p(k-Kd1a)              for k = Kd1a, Kd1a+1, â¦, Kd1a+5
u(k) = d(k-6)                    for k = Kd1a+6, Kd1a+7, â¦, Ku-1
Thus, after the first encoding step u(k) will be defined by the following contents for each codec mode:

            u(k) = d(k)                        for k = 0, 1, â¦, 80

            u(k) = d(k-6)                    for k = 61, 62, â¦, 139

and
     e(B,57) = hl(B) and e(B,58) = hu(B)
The two symbols, labelled hl(B) and hu(B) on burst number B are flags used for indication of control channel signalling. For each O-TCH/AHS block not stolen for signalling purposes:
     hu(B) = {0,0,0}   for the first 2 bursts (indicating status of the even numbered symbols)
     hl(B) = {0,0,0}  for the last 2 bursts (indicating status of the odd numbered symbols)
     where {0,0,0} is the mapping of the three bits 0,0,0 onto a 3-bit symbol according to table 1 in 3GPP TS 45.004.

The general coding is as: the two in-band data channels are coded to 16 bits each, a 14-bit CRC is added to the 35 CN bits which are then coded by a rate ¼ RSC coder to 212 bits. Finally a 212 bits identification field is added thereby giving a total size of 456 bits. These 456 bits are then block interleaved in the same way as SACCH frames.

Adjoining each block of data is information of the channel codec mode to use when encoding the block. Also delivered is the in-band data id(0,1) representing Mode Indication or Mode Command/Mode Request depending on the current frame number.
3.16.4.1Â Â Â Â Â Â Â Â Â Coding of the in-band data
The two input in-band bits (id(0,1)) are coded to twenty four coded in-band bits (ic(0..23)).
The encoded in-band bits are moved to the coded bits, c, as
     c(k) = ic(k)          for k = 0, 1, ..., 23.
3.16.4.2Â Â Â Â Â Â Â Â Â Ordering according to subjective importance
The bits delivered by the speech encoder, {s(1),s(2),...,s(Ks)}, are rearranged according to subjective importance before channel coding. Tables 16 to 20 define the correct rearrangement for the speech codec modes 12.65 kbit/s, 8.85 kbit/s 6.60 kbit/s, 23.85 kbit/s and 15.85 kbit/s, respectively. In the tables speech codec parameters are numbered in the order they are delivered by the corresponding speech encoder according to 3GPP TS 26.190 and the rearranged bits are labelled {d(0),d(1),...,d(Kd-1)}, defined in the order of decreasing importance. Index Kd refers to the number of bits delivered by the speech encoder, see below:

The ordering algorithm is in pseudo code as:
     for j = 0 to Kd-1  d(j) := s(table(j)+1);             where table(j) is read line by line left to right
The rearranged bits are further divided into two different classes to perform unequal error protection for different bits according to subjective importance.
The protection classes are:
            1a -    Data protected with the CRC
and the convolution code.
     1b -    Data protected with the convolution code.
The number of class 1 (sum of class 1a and 1b), class 1a and class 1b bits for each codec mode is shown below:

A 6-bit CRC
is used for error-detection. These parity bits are generated by the cyclic
generator polynomial:
g(D) = D6 + D5 + D3 + D2 + D1
+ 1 from the first Kd1a bits of class 1, where Kd1a
refers to number of bits in protection class 1a as shown above for each codec
mode. The encoding of the cyclic code is performed in a systematic form, which
means that, in GF(2), the polynomial:
d(0)D(Kd1a+5) + d(1)D(Kd1a+4) +... + d(Kd1a-1)D(6) + p(0)D(5) +â¦+ p(4)D+ p(5)
where p(0), p(1) ⦠p(5) are the parity bits, when divided by g(D), yields a remainder equal to:
1+ D + D2 + D3 + D4 + D5.
The information and parity bits are merged:
u(k) = d(k)                        for k = 0, 1, â¦, Kd1a-1
u(k) = p(k-Kd1a)              for k = Kd1a, Kd1a+1, â¦, Kd1a+5

Below the coding for each codec mode is specified in detail. The puncturing for each mode is designed to give an even protection of the class 1A bits while the protection within class 1B is not equal to reflect the individual error sensitivity of the class 1B bits.
O-TCH/WFS23.85:
The block of 483 bits {u(0)⦠u(482)} is encoded with the 1/3 rate convolutional code defined by  the following
            G4/G7 = 1 + D2  + D3 + D5 + D6/1 + D + D2 + D3 + D6
     G5/G7 = 1 + D + D4 + D6/1 + D + D2 + D3 + D6
G7/G7 = 1
     resulting in 1467 coded bits, {C(0)⦠C(1466)} defined by:
            r(k)            = u(k) + r(k-1) + r(k-2) + r(k-3) + r(k-6)

3.16.4.5Â Â Â Â Â Â Â Â Â Interleaving
Before interleaving the bits {PC'(0) ⦠PC'(1367)} are converted into 3-bit symbols {c(0) ⦠c(455)} according to table 1 in 3GPP TS 45.004, the symbol c(k) consists of d3k=PC'(k), d3k+1=PC'(k+456) and d3k+2=PC'(k+912) for k=0,1,â¦,456. The interleaving is done as specified for the TCH/FS in subclause 3.1.3. The difference is that the interleaving is done by symbols instead of single bits, reusing the existing interleaving tables.
3.16.4.6Â Â Â Â Â Â Â Â Â Mapping on a Burst
The mapping is done as specified for the TCH/FS in subclause 3.1.4 with exception that it is done by symbols instead of single bits.
3.16.5Â Â Â RATSCCH
The RATSCCH message consists of 35 bits. Also delivered are two in-band channels, id0(0,1) and id1(0,1), id0 corresponding to Mode Commands or Mode Requests and id1 to Mode Indication. The general coding is as: the two in-band data channels are coded to 16 bits each, a 14-bit CRC is added to the 35 RATSCCH bits which are then coded by a rate ¼ RSC coder to 212 bits. Finally a 212 bit identification field is added thereby giving a total size of 456 bits. These 456 bits are then block interleaved in the same way as a normal speech frame.
3.16.5.1Â Â Â Â Â Â Â Â Â Coding of in-band data
The coding of in-band data is done as specified for the RATSCCH message in TCH/AFS (subclause 3.9.5.1).
3.16.5.2Â Â Â Â Â Â Â Â Â Parity and convolutional encoding for the RATSCCH message
The parity and convolutional encoding for the RATSCCH message are done as specified for the RATSCCH message in TCH/AFS (subclause 3.9.5.2).
3.16.5.3Â Â Â Â Â Â Â Â Â Identification marker
The identification marker is done as specified for the RATSCCH message in TCH/AFS (subclause 3.9.5.3).
3.16.5.4Â Â Â Â Â Â Â Â Â Interleaving
Before interleaving the bits are repeated 3 times:
c'(3k+2) = c'(3k+1) = c'(3k) = c(k)       for k=0,â¦,455
The bits {c'(0) ⦠c'(1367)} are then converted into 3-bit symbols {C(0) ⦠C(455)} according to table 1 in 3GPP TS 45.004, the symbol C(k) depends on c'(3k+2), c'(3k+1) and c'(3k) for k=0,1,â¦,455.
The interleaving is done as specified for the TCH/AFS (subclause 3.9.5.4). The difference is that the interleaving is done by symbols instead of single bits, reusing the existing interleaving tables.
3.16.5.5Â Â Â Â Â Â Â Â Â Mapping on a Burst
The mapping is done as specified for the TCH/AFS (subclause 3.9.5.5) with exception that it is done by symbols instead of single bits.

3.17.1 Â Â Â SID_UPDATE
The speech encoder delivers 35 bits of comfort noise parameters. Also delivered is two in-band channels, id0(0,1) and id1(0,1), id0 corresponding to Mode Commands/Mode Requests and id1 to Mode Indication. The general coding is as: the two in-band data channels are coded to 16 bits each, a 14-bit CRC is added to the 35 CN bits which are then coded by a rate ¼ RSC coder to 212 bits. A 212 bit identification field is added thereby giving a total size of 456 bits. Finally each bit is repeated 3 times and then converted into 3-bit symbols giving a total size of 456 symbols.

3.17.7Â Â Â SPEECH
The speech coder delivers to the channel encoder a sequence of blocks of data. One block of data corresponds to one speech frame and the block length is different in each of the nine channel codec modes. Adjoining each block of data is information of the channel codec mode to use when encoding the block. Also delivered is the in-band data id(0,1) representing Mode Indication or Mode Command/Mode Request depending on the current frame number.
3.17.7.1Â Â Â Â Â Â Â Â Â Coding of the in-band data
The two input in-band bits (id(0,1)) are coded to twelve coded in-band bits (ic(0..11)).
The encoded in-band bits are moved to the coded bits, c, as
     c(k) = ic(k)          for k = 0, 1, ..., 11.
3.17.7.2Â Â Â Â Â Â Â Â Â Ordering according to subjective importance
The bits delivered by the speech encoder, {s(1),s(2),...,s(Ks)}, are rearranged according to subjective importance before channel coding. Tables 16 to 18 define the correct rearrangement for the speech codec modes 12.65 kbit/s, 8.85 kbit/s and 6.60 kbit/s, respectively. In the tables speech codec parameters are numbered in the order they are delivered by the corresponding speech encoder according to 3GPP TS 26.190 and the rearranged bits are labelled {d(0),d(1),...,d(Kd-1)}, defined in the order of decreasing importance. Index Kd refers to the number of bits delivered by the speech encoder, see below:

The ordering algorithm is in pseudo code as:
     for j = 0 to Kd-1  d(j) := s(table(j)+1);             where table(j) is read line by line left to right
The rearranged bits are further divided into two different classes to perform unequal error protection for different bits according to subjective importance.
The protection classes are:
            1a -    Data protected with the CRC
and the convolution code.
     1b -    Data protected with the convolution code.
The number of class 1 (sum of class 1a and 1b), class 1a and class 1b bits for each codec mode is shown below:

A 6-bit CRC
is used for error-detection. These parity bits are generated by the cyclic
generator polynomial:
g(D) = D6 + D5 + D3 + D2 + D1
+ 1 from the first Kd1a bits of class 1, where Kd1a
refers to number of bits in protection class 1a as shown above for each codec
mode. The encoding of the cyclic code is performed in a systematic form, which
means that, in GF(2), the polynomial:
d(0)D(Kd1a+5) + d(1)D(Kd1a+4) +... + d(Kd1a-1)D(6) + p(0)D(5) +â¦+ p(4)D+ p(5)
where p(0), p(1) ⦠p(5) are the parity bits, when divided by g(D), yields a remainder equal to:
1+ D + D2 + D3 + D4 + D5.
The information and parity bits are merged:
u(k) = d(k)                        for k = 0, 1, â¦, Kd1a-1
u(k) = p(k-Kd1a)              for k = Kd1a, Kd1a+1, â¦, Kd1a+5
u(k) = d(k-6)                    for k = Kd1a+6, Kd1a+7, â¦, Ku-1

            u(k) = d(k)                        for k = 0, 1, ..., 71
            u(k) = p(k-72)                  for k = 72, 73, â¦, 77
            u(k) = d(k-6)                    for k = 78, 79, â¦, 258
O-TCH/WHS8.85:
          u(k) = d(k)                        for k = 0, 1, â¦, 63

            u(k) = d(k-6)                    for k = 70, 71, â¦, 182
O-TCH/WHS6.60:
            u(k) = d(k)                        for k = 0, 1, ..., 53
            u(k) = p(k-54)                  for k = 54, 55, ..., 59
            u(k) = d(k-6)                    for k = 60, 61, ..., 137

Below the coding for each codec mode is specified in detail. The puncturing for each mode is designed to give an even protection of the class 1A bits while the protection within class 1B is not equal to reflect the individual error sensitivity of the class 1B bits.
O-TCH/WHS12.65:
     The block of 259 bits {u(0)⦠u(258)} is encoded with the 1/3 rate convolutional code defined by the following polynomials:
            G4/G7 = 1 + D2  + D3 + D5 + D6/1 + D + D2 + D3 + D6
     G5/G7 = 1 + D + D4 + D6/1 + D + D2 + D3 + D6
G7/G7 = 1
     resulting in 795 coded bits, {C(0)⦠C(794)} defined by:
            r(k)            = u(k) + r(k-1) + r(k-2) + r(k-3) + r(k-6)

     and (for termination of the coder):
            r(k)            = 0
            C(3k)        = r(k) + r(k-2) + r(k-3) + r(k-5) + r(k-6)

4.1Â Â Â Â Â Â Â Slow associated control channel (SACCH)
4.1.1Â Â Â Â Â Â Block constitution
The message delivered to the encoder has a fixed size of 184 information bits {d(0),d(1),...,d(183)}. It is delivered on a burst mode.
4.1.2Â Â Â Â Â Â Block code
a)Â Â Parity bits:
     The block of 184 information bits is protected by 40 extra bits used for error correction and detection. These bits are added to the 184 bits according to a shortened binary cyclic code (FIRE code) using the generator polynomial:
     g(D) = (D23 + 1)*(D17 + D3 + 1)
     The encoding of the cyclic code is performed in a systematic form, which means that, in GF(2), the polynomial:
d(0)D223Â + d(1)D222 +...+d(183)D40Â + p(0)D39 + p(1)D38 +...+p(38)D + p(39)
     where {p(0),p(1),...,p(39)} are the parity bits , when divided by g(D) yields a remainder equal to:
     1 + D + D2 +...+ D39.
b)Â Â Tail bits
     Four tail bits equal to 0 are added to the information and parity bits, the result being a block of 228 bits.
     u(k) = d(k)           for k= 0,1,...,183
     u(k) = p(kâ184)   for k = 184,185,...,223
     u(k) = 0                for k = 224,225,226,227 (tail bits)
4.1.3Â Â Â Â Â Â Convolutional encoder
This block of 228 bits is encoded with the ½ rate convolutional code (identical to the one used for TCH/FS) defined by the polynomials:
G0 = 1 + D3Â + D4
G1 = 1 + D + D3Â + D4
This results in a block of 456 coded bits: {c(0),c(1),...,c(455)} defined by:
c(2k)Â Â Â Â Â Â Â Â Â = u(k) + u(kâ3) + u(kâ4)
c(2k+1) Â Â Â = u(k) + u(kâ1) + u(kâ3) + u(kâ4)Â Â Â Â Â Â Â Â Â Â for k = 0,1,...,227 ; u(k) = 0 for k < 0
4.1.4Â Â Â Â Â Â Interleaving
The coded bits are reordered and interleaved according to the following rule:
i(B,j) = c(n,k) for k = 0,1,...,455
            n = 0,1,...,N,N+1,...  Â
            B = B0 + 4n + (k mod 4)
            j = 2((49k) mod 57) + ((k mod 8) div 4)
See table 1. The result of the reordering of bits is the same as given for a TCH/FS (subclause 3.1.3) as can be seen from the evaluation of the bit numberâindex j, distributing the 456 bits over 4 blocks on even numbered bits and 4 blocks on odd numbered bits. The resulting 4 blocks are built by putting blocks with even numbered bits and blocks with odd numbered bits together into one block.
The block of coded data is interleaved "block rectangular" where a new data block starts every 4th block and is distributed over 4 blocks.
4.1.5Â Â Â Â Â Â Mapping on a Burst
The mapping is given by the rule:
e(B,j)        = i(B,j)     and     e(B,59+j) = i(B,57+j)     for j = 0,1,...,56
and
e(B,57)    = hl(B)     and     e(B,58) = hu(B)
The two bits labelled hl(B) and hu(B) on burst number B are flags used for indication of control channel signalling. They are set to "1" for a SACCH.
4.2Â Â Â Â Â Â Â Fast associated control channel at full rate (FACCH/F)

4.2.2Â Â Â Â Â Â Block code
The block encoding is done as specified for the SACCH in subclause 4.1.2.
4.2.3Â Â Â Â Â Â Convolutional encoder
The convolutional encoding is done as specified for the SACCH in subclause 4.1.3.
4.2.4Â Â Â Â Â Â Interleaving
The interleaving is done as specified for the TCH/FS in subclause 3.1.3.
4.2.5Â Â Â Â Â Â Mapping on a Burst
A FACCH/F frame of 456 coded bits is mapped on 8 consecutive bursts as specified for the TCH/FS in subclause 3.1.4. As a FACCH is transmitted on bits which are stolen in a burst from the traffic channel, the even numbered bits in the first 4 bursts and the odd numbered bits of the last 4 bursts are stolen.
To indicate this to the receiving device the flags hl(B) and hu(B) have to be set according to the following rule:
hu(B) = 1 for the first 4 bursts  (even numbered bits are stolen);
hl(B) = 1 for the last 4 bursts   (odd numbered bits are stolen).
The consequences of this bitstealing by a FACCH/F is for a:
â    speech channel (TCH/FS) and data channel (TCH/F2.4):
     One full frame of data is stolen by the FACCH.
â    Data channel (TCH/F14.4):
     The bitstealing by a FACCH/F disturbs a maximum of 96 of the 456 coded bits generated from an input data block of 290 bits.
â    Data channel (TCH/F9.6):
     The bitstealing by a FACCH/F disturbs a maximum of 96 coded bits generated from an input frame of four data blocks. A maximum of 24 of the 114 coded bits resulting from one input data block of 60 bits may be disturbed.
â    Data channel (TCH/F4.8):
     The bit stealing by FACCH/F disturbs a maximum of 96 coded bits generated from an input frame of two data blocks. A maximum of 48 of the 228 coded bits resulting from one input data block of 60 bits may be disturbed.
NOTE:Â Â Â Â Â In the case of consecutive stolen frames, a number of bursts will have both the even and the odd bits stolen and both flags hu(B) and hl(B) must be set to 1.
4.3Â Â Â Â Â Â Â Fast associated control channel at half rate (FACCH/H)
4.3.1Â Â Â Â Â Â Block constitution

4.3.2Â Â Â Â Â Â Block code
The block encoding is done as specified for the SACCH in subclause 4.1.2.
4.3.3Â Â Â Â Â Â Convolutional encoder
The convolutional encoding is done as specified for the SACCH in subclause 4.1.3.
4.3.4Â Â Â Â Â Â Interleaving
The coded bits are reordered and interleaved according to the following rule:
i(B,j) = c(n,k) for k = 0,1,...,455
                  n = 0,1,...,N,N+1,...
                  B = B0 + 4n + (k mod 8) â 4((k mod 8) div 6)
                  j = 2((49k) mod 57) + ((k mod 8) div 4)
See table 1. The result of the reordering of bits is the same as given for a TCH/FS (subclause 3.1.3) as can be seen from the evaluation of the bit numberâindex j, distributing the 456 bits over 4 blocks on even numbered bits and 4 blocks on odd numbered bits. The 2 last blocks with even numbered bits and the 2 last blocks with odd numbered bits are put together into 2 full middle blocks.
The block of coded data is interleaved "block diagonal" where a new data block starts every 4th block and is distributed over 6 blocks.
4.3.5Â Â Â Â Â Â Mapping on a Burst
A FACCH/H frame of 456 coded bits is mapped on 6 consecutive bursts by the rule:
e(B,j) = i(B,j)       and    e(B,59+j) = i(B,57+j)     for j = 0,1,...,56
and
e(B,57) = hl(B)   and    e(B,58) = hu(B)
As a FACCH/H is transmitted on bits which are stolen from the traffic channel, the even numbered bits of the first 2 bursts, all bits of the middle 2 bursts and the odd numbered bits of the last 2 bursts are stolen.
To indicate this to the receiving device the flags hl(B) and hu(B) have to be set according to the following rule:
     hu(B) = 1                          for the first 2 bursts (even numbered bits are stolen)
     hu(B) = 1 and hl(B) = 1 for the middle 2 bursts (all bits are stolen)
     hl(B) = 1                           for the last 2 bursts (odd numbered bits are stolen)
The consequences of this bitstealing by a FACCH/H is for a:
â    speech channel (TCH/HS):
     two full consecutive speech frames are stolen by a FACCH/H.
â    data channel (TCH/H4.8):
     The bitstealing by FACCH/H disturbs a maximum of 96 coded bits generated from an input frame of four data blocks. A maximum of 24 out of the 114 coded bits resulting from one input data block of 60 bits may be disturbed.
â    data channel (TCH/H2.4):
     The bitstealing by FACCH/H disturbs a maximum of 96 coded bits generated from an input frame of four data blocks. A maximum of 24 out of the 114 coded bits resulting from one input data block of 36 bits may be disturbed.
NOTE:Â Â Â Â Â In the case of consecutive stolen frames, two overlapping bursts will have both the even and the odd numbered bits stolen and both flags hu(B) and hl(B) must be set to 1.
4.4Â Â Â Â Â Â Â Broadcast control, Paging, Access grant, Notification and Cell broadcast channels (BCCH, PCH, AGCH, NCH, CBCH), CTS Paging and Access grant channels (CTSPCH, CTSAGCH)
The coding scheme used for the broadcast control , paging, access grant, notification and cell broadcast messages is the same as for the SACCH messages, specified in subclause 4.1. In CTS, the coding scheme used for the paging and access grant messages is also the same as for the SACCH messages, specified in subclause 4.1.
4.5Â Â Â Â Â Â Â Standâalone dedicated control channel (SDCCH)
The coding scheme used for the dedicated control channel messages is the same as for SACCH messages, specified in subclause 4.1.
4.6Â Â Â Â Â Â Â Random access channel (RACH)
Two coding schemes are specified for the burst carrying the random access uplink message: the access burst containing 8 information bits and the access burst containing 11 information bits.
The encoding of the access burst containing 11 information bits is as defined in section 5.3.2 for the packet random access channel (PRACH and CPRACH).
The encoding of the
access burst containing 8 information bits is defined as follows. It contains 8
information bits
d(0),d(1),...,d(7).
Six parity bits p(0),p(1),...,p(5) are defined in such a way that in GF(2) the binary polynomial:
     d(0)D13 +...+ d(7)D6 + p(0)D5 +...+ p(5), when divided by D6 + D5 + D3 + D2 + D + 1 yields a remainder equal to D5 + D4 + D3 + D2 + D + 1.
The six bits of the BSIC, {B(0),B(1),...,B(5)}, of the BS to which the Random Access is intended, are added bitwise modulo 2 to the six parity bits, {p(0),p(1),...,p(5)}. This results in six colour bits, C(0) to C(5) defined as C(k) = b(k) + p(k) (k = 0 to 5) where:
b(0) = MSB of PLMN colour code
b(5) = LSB of BS colour code.
This defines {u(0),u(1),..., u(17)} by:
u(k)Â Â Â Â = d(k)Â Â Â Â Â Â Â for k = 0,1,...,7
u(k)Â Â Â Â = C(kâ8)Â Â Â for k = 8,9,...,13
u(k)Â Â Â Â = 0Â Â Â Â Â Â Â Â Â Â Â Â for k = 14,15,16,17 (tail bits)
The bits {e(0),e(1),..., e(35)} are obtained by the same convolutional code of rate ½ as for TCH/FS, defined by the polynomials:
G0 = 1 + D3Â + D4
G1 = 1 + D + D3Â + D4
and with:
e(2k)Â Â Â Â Â Â Â Â Â = u(k) + u(kâ3) + u(kâ4)
e(2k+1)Â Â Â Â = u(k) + u(kâ1) + u(kâ3) + u(kâ4)Â Â Â Â Â Â Â Â Â Â for k = 0,1,...,17 ; u(k) = 0 for k < 0
4.7Â Â Â Â Â Â Â Synchronization channel (SCH), Compact synchronization channel (CSCH), CTS Beacon and Access request channels (CTSBCH-SB, CTSARCH)
The burst carrying the synchronization information on the downlink BCCH, the downlink CPBCCH for Compact, and in CTS the information of the CTSBCH-SB and the access request message of the CTSARCH, has a different structure. It contains 25 information bits {d(0),d(1),..., d(24)}, 10 parity bits {p(0),p(1),..., p(9)} and 4 tail bits. The precise ordering of the information bits is given in 3GPP TS 44.018.
The ten parity bits {p(0),p(1),,...,p(9)} are defined in such a way that in GF(2) the binary polynomial:
d(0)D34Â +...+ d(24)D10Â + p(0)D9Â +...+ p(9), when divided by:
D10Â + D8Â + D6Â + D5Â + D4Â + D2Â + 1, yields a remainder equal to:
D9Â + D8Â + D7Â + D6Â +Â D5Â +Â D4Â + D3Â + D2Â + D+ 1.
Thus the encoded bits {u(0),u(1),...,u(38)} are:
u(k)Â Â Â Â = d(k)Â Â Â Â Â Â Â Â Â Â Â Â Â for k = 0,1,...,24
u(k)Â Â Â Â = p(kâ25)Â Â Â Â Â Â Â for k = 25,26,...,34
u(k)Â Â Â Â = 0Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â for k = 35,36,37,38 (tail bits)
The bits {e(0),e(1),..., e(77)} are obtained by the same convolutional code of rate ½ as for TCH/FS, defined by the polynomials:
G0 = 1 + D3Â + D4
G1 = 1 + D + D3Â + D4
and with:
e(2k)Â Â Â Â Â Â Â Â Â = u(k) + u(kâ3) + u(kâ4)
e(2k+1)Â Â Â Â = u(k) + u(kâ1) + u(kâ3) + u(kâ4)Â Â Â Â Â Â Â Â Â Â for k = 0,1,....,38 ; u(k) = 0 for k < 0
4.8Â Â Â Â Â Â Â Access Burst on circuit switched channels other than RACH
The encoding of this burst is as defined in subclause 4.6 for the 8 bits access burst on the random access channel (RACH). The BSIC used shall be the BSIC of the BTS to which the burst is intended.
4.9Â Â Â Â Â Â Â Access Bursts for uplink access on a channel used for VGCS
The encoding of this burst is as defined in subclause 4.6 for the 8 bits access burst on the RACH. The BSIC used by the Mobile Station shall be the BSIC indicated by network signalling, or if not thus provided, the last received BSIC on the SCH of the current cell.
4.10a   Fast associated control channel at ECSD E-TCH/F (E-FACCH/F)
4.10a.1Â Block constitution
The message delivered to the encoder has a fixed size of 184 information bits. It is delivered on a burst mode.
4.10a.2Â Block code
The block encoding is done as specified for the SACCH in subclause 4.1.2.
4.10a.3Â Convolutional encoder
The convolutional encoding is done as specified for the SACCH in subclause 4.1.3.
4.10a.4Â Interleaving
The interleaving is done as specified for the SACCH in subclause 4.1.4.
4.10a.5Â Mapping on a Burst
A E-FACCH/F frame of 456 coded bits is mapped on 4 full consecutive bursts. As a E-FACCH/F is transmitted on bits, which are stolen in a burst from the ECSD traffic channel, the four full bursts are stolen.
The mapping on is given by the rule:
            e(B,j)=i(B,j) and e(B,59+j)=i(B,57+j) for j=0,1,â¦,56
and
            e(B,57)=hl(B) and e(B,58)=hu(B).
To indicate to the receiving device the flags hl(B) and hu(B) have to be set according to the following rule:
            hu(B)=1 and hl(B)=1 for the all 4 bursts (4 full bursts are stolen).
The consequences of this bitstealing by a E-FACCH/F is for a:
-Â Â Â Â Data channel (E-TCH/F43.2)
     The bitstealing by a E-FACCH/F disturbs a maximum of 288 of the 1368 coded bits generated from an input data block of 870 bits.
-Â Â Â Â Data channel (E-TCH/F32.0)
     The bitstealing by a E-FACCH/F disturbs 464 of the 1392 coded bits generated from an input data block of 640 bits.
-Â Â Â Â Data channel (E-TCH/F28.8)
     The bitstealing by a E-FACCH/F disturbs a maximum of 288 of the 1368 coded bits generated from an input data block of 580 bits.
4.10b Octal fast associated control channel at half rate (O-FACCH/H)
4.10b.1Â Â Â Â Â Block constitution
The message delivered to the encoder has a fixed size of 184 information bits. It is delivered on a burst mode.
4.10b.2Â Â Â Â Â Block code
a)Â Â Parity bits:
The block of 184 information bits is protected by 40 extra bits used for error correction and detection. These bits are added to the 184 bits according to a shortened binary cyclic code (FIRE code) using the generator polynomial:
     G(D)=(D23 + 1)(D17 + D3 + 1)
The encoding of the cyclic code is performed in a systematic form, which means that, in GF(2), the polynomial:
D(0)D223 + d(1)D222 +â¦+ d(183)D40 + p(0)D39 + p(1)D38 +â¦+ p(38)D + p(39)
where {p(0),p(1),â¦,p(39)} are the parity bits, when divided by g(D) yields a remainder equal to:
     1 + D + D2 +⦠+D39.
b)Â Â Tail bits
Six tail bits equal to zero are added to the information and parity bits, the result being a block of 230 bits.
         u(k) = d(k)            for k = 0,1,â¦,183
         u(k) = p(k-184)   for k = 184,185,â¦,223
         u(k) = 0                 for k = 224,225,226,227,228,229 (tail bits)
4.10b.3Â Â Â Â Â Convolutional encoder
This block of 230 bits is encoded with the rate 1/6 convolutional code defined by the polynomials:
     G4 = 1 + D2 + D3 + D5 + D6
     G4 = 1 + D2 + D3 + D5 + D6
     G5 = 1 + D + D4 + D6
     G5 = 1 + D + D4 + D6
     G6 = 1 + D + D2 + D3 + D4 + D6
     G7 = 1 + D + D2 + D3 + D6
This results in a block of 1380 encoded bits {C(0),C(1),â¦C(1379)} defined by
     C(6k) = u(k) + u(kâ2) + u(k-3) + u(kâ5) + u(k-6)
     C(6k+1) = u(k) + u(kâ2) + u(k-3) + u(kâ5) + u(k-6)
     C(6k+2) = u(k) + u(kâ1) + u(kâ4) + u(kâ6)
     C(6k+3) = u(k) + u(kâ1) + u(kâ4) + u(kâ6)
     C(6k+4) = u(k) + u(k-1) + u(k-2) + u(k-3) + u(k-4) + u(k-6)
     C(6k+5) = u(k) + u(k-1) + u(k-2) + u(k-3) + u(k-6)          for k = 0,1,...,229 ; u(k) = 0 for k < 0
The code is punctured in such a way that the following coded bits:
     {C(21+114k) for k=0,1,..,11} are not transmitted.
The result is a block of 1368 coded bits {c(0),c(1),â¦,c(1367)}.
4.10b.4Â Â Â Â Â Reordering
The coded bits are reordered according to the following rule:
            r(j) = c(k), for k = 0,1,...,1367
                                     j  = k div 36 + 38*(k mod 36)
NOTE:Â Â Â Â Â The reordering is a simple block interleaver: a 38 rows x 36 columns matrix which is filled in by row and read out by column.
4.10b.5Â Â Â Â Â Interleaving
Before interleaving the reordered coded bits {r(0),r(1),â¦,r(1367)} are converted into 3-bit symbols {Rs(0),Rs(1),â¦,Rs(455)} according to Table 1 in 3GPP TS 45.004, the symbol Rs(k) depends on r(3k+2), r(3k+1), and r(3k) for k=0,1,â¦,455. The interleaving is done as specified for the FACCH at half rate in subclause 4.3.4. The difference is that the interleaving is done by symbols instead of single bits, reusing the existing interleaving tables.
4.10b.6Â Â Â Â Â Mapping on a burst
As an O-FACCH is transmitted on symbols which are stolen in a burst from the traffic channel, the even numbered symbols in the first 2 bursts, all symbols in the middle 2 bursts, and the odd numbered symbols in the last 2 bursts are stolen.
The mapping is given by the rule:
     E(B,j) = I(B,j) and E(B,59+j) = I(B,57+j) for j=0,1,â¦,56
and
     E(B,57) = HL(B) and E(B,58) = HU(B).
To indicate the stealing to the receiving device the symbols HL(B) and HU(B) have to be set according to the following rule:
     HU(B) = {1,1,1} for the first two bursts (even numbered symbols are stolen)
     HU(B) = {1,1,1} and HL(B) = {1,1,1} for the middle two bursts (all symbols are stolen)
     HL(B) = {1,1,1} for the last two burts (odd numbered symbols are stolen).
As a consequence, two full consecutive speech frames of an O-TCH/AHS are stolen by an O-FACCH/H.
4.10c Octal fast associated control channel at full rate (O-FACCH/F)
4.10c.1Â Block constitution
The message delivered to the encoder has a fixed size of 184 information bits. It is delivered on a burst mode.
4.10c.2Â Â Â Â Â Block code
The block encoding is done as specified for the O-FACCH/H in subclause 4.10b.2
4.10c.3Â Â Â Â Â Convolutional encoder
The convolutional encoding is done as specified for the O-FACCH/H in subclause 4.10b.3.
4.10c.4Â Â Â Â Â Reordering
The reordering is done as specified for the O-FACCH/H in subclause 4.10b.4.
4.10c.5Â Â Â Â Â Interleaving
Before interleaving the reordered coded bits {r(0),r(1),â¦,r(1367)} are converted into 3-bit symbols {Rs(0),Rs(1),â¦,Rs(455)} according to Table 1 in 3GPP TS 45.004, the symbol Rs(k) depends on r(3k+2), r(3k+1), and r(3k) for k=0,1,â¦,455. The interleaving is done as specified for the FACCH at full rate in subclause 4.2.4. The difference is that the interleaving is done by symbols instead of single bits, reusing the existing interleaving tables.
4.10c.6Â Â Â Â Â Mapping on a burst
As an O-FACCH is transmitted on symbols which are stolen in a burst from the traffic channel, the even numbered symbols in the first four bursts and the odd numbered symbols in the last four bursts are stolen.
The mapping is given by the rule:
                                                 E(B,j) = I(B,j) and E(B,59+j) = I(B,57+j) for j=0,1,â¦,56
and
                                                                E(B,57) = HL(B) and E(B,58) = HU(B).
To indicate the stealing to the receiving device the symbols HL(B) and HU(B) have to be set according to the following rule:
                               HU(B) = {1,1,1} for the first four bursts (even numbered symbols are stolen)
                                 HL(B) = {1,1,1} for the last four burts (odd numbered symbols are stolen).
As a consequence, one speech frame of an O-TCH/F is stolen by an O-FACCH/F.
4.11Â Â Â Â Â Slow associated control channel with embedded enhanced power control (SACCH/TP)
4.11.1Â Â Â Block constitution
The message delivered to the encoder has a fixed size of 184 information bits {d(0),d(1),...,d(183)}. It is delivered on a burst mode.
4.11.2Â Â Â Block code
a)Â Â Parity bits:
     Eighteen parity bits p(0),p(1),...,p(17) are defined in such a way that in GF(2) the binary polynomial:
d(0)D201Â +...+ d(183)D18Â + p(0)D17+...+ p(17), when divided by:
D18Â + D17Â + D14Â + D13Â + D11Â + D10Â + D8Â + D7Â + D6Â + D3Â + D2Â + 1, yields a remainder equal to:
D17Â + D16Â + D15Â + D14Â + D13Â + D12Â + D11Â + D10Â + D9Â + D8Â + D7Â + D6Â + D5Â + D4Â + D3Â + D2Â + D+1.
b)Â Â Tail bits
     Six tail bits equal to 0 are added to the information and parity bits, the result being a block of 208 bits.
     u(k) = d(k)           for k= 0,1,...,183
     u(k) = p(kâ184)   for k = 184,185,...,201
     u(k) = 0                for k = 202,203,204,205,206,207 (tail bits)
4.11.3Â Â Â Convolutional encoder
This block of 208 bits is encoded with the ½ rate convolutional code defined by the polynomials:
G4 = 1 + D2Â + D3Â + D5Â + D6
G7= 1 + D + D2Â + D3Â + D6
This results in a block of 416 coded bits: {c'(0),c'(1),...,c'(415)} defined by:
c'(2k)Â Â Â Â Â Â Â Â = u(k) + u(k-2) + u(kâ3) +Â u(k-5) + u(k-6)
c'(2k+1) Â Â = u(k) + u(kâ1) + u(k-2) + u(kâ3) + u(k-6)Â Â Â Â Â Â Â for k = 0,1,...,207 ; u(k) = 0 for k < 0
4.11.4Â Â Â Dummy bits insertion

4.12.2Â Â Â Mapping on a Burst
The EPCCH message is mapped on the SACCH/TP burst.

5.1Â Â Â Â Â Â Â Packet data traffic channel (PDTCH)
Thirteen coding schemes are specified for the packet data traffic channels. For the coding schemes CS-2 to CS-4 and MCS-1 to MCS-4, the first three bits (USF-bits) of the data block are encoded such that the first twelve coded bits are representing the same bit pattern, irrespective of the coding scheme, depending only on the USF-bits. For these coding schemes, the USF-bits can therefore always be decoded from these twelve bits in the same way. It should be noted that the USF precoding is done in the uplink direction for coding schemes CS-2 â CS-4, despite the fact that uplink RLC data block structure (3GPP TS 44.060) does not define USF-field.
For the nine coding schemes MCS-1 to MCS-9, the block structure differs between uplink and downlink since header sizes before coding are not the same.
In BTTI configuration, the RLC/MAC layer delivers to the encoder one data block every 20 ms. In RTTI configuration, the RLC/MAC layer delivers to the encoder one data block every 10 ms or, if BTTI USF mode is used (see 3GPP TS 45.002), the RLC/MAC layer in the downlink may deliver to the encoder two data blocks every 20 ms.
In the downlink direction, if BTTI USF mode is used (see 3GPP TS 45.002), one value of the USF per PDCH is delivered to the encoder every 20 ms; if RTTI USF mode is used (see 3GPP TS 45.002), one value of the USF per corresponding downlink PDCH-pair is delivered to the encoder every 10 ms.
If BTTI USF mode is used when sending downlink data blocks in RTTI configuration, then the USF need not be delivered to the encoder as the first three bits of a data block. In this case, the first three bits of a data block are set to an unspecified value (see 3GPP TS 44.060).
NOTE:Â Â Â Â Â How the USFs are delivered to the encoder in this case is implementation dependent.
If BTTI USF mode is used when sending downlink data blocks in RTTI configuration, then both data blocks sent in a 20 ms block period shall be encoded using coding schemes with the same modulation, unless
· Reduced Latency is supported by the MS to which the USF is intended or
· EGPRS2 is supported by the MS to which the USF is intended or
· The USF to be transmitted is set to an unused value (see 3GPP TS 45.002).
If an MS, that neither supports Reduced Latency nor EGPRS2, receives in a 20ms block period data blocks sent using different modulations, the MS shall ignore the USF.
If BTTI USF mode is used when sending downlink data blocks in RTTI configuration and different modulations are used in the two data blocks sent in a 20 ms block period, the USF will be sent with mixed modulation. In this case, the coding of the USF bits sent in the first 10 ms block period is according to the MCS used in that block period, while the coding of the USF bits sent in the second 10 ms block period is according to the MCS used in that block period. The network shall use only MCSs supported by the MS to which the USF is intended.

In RTTI configuration with RTTI USF mode, the bursts with B = 0,2 shall be mapped on the PDCH having the lower timeslot number, whereas the bursts with B = 1,3 shall be mapped on the PDCH having the higher timeslot number, see 3GPP TS 45.002.

5.1.5.1.4a           Piggy-backed Ack/Nack coding
The operations in this subclause shall be carried out only if a PAN field is included.
a)Â Â Parity bits

d(209)D29 +...+ d(228)D10 + p(0)D9 +...+ p(9), when divided by:
D10 + D9 + D5 + D4 + D + 1, yields a remainder equal to:

b)Â Â Tail bits:
     Six tail bits equal to 0 are added to the
information and parity bits, the result being a block of 316 bits
{u(0),u(1),...,u(315)}:
u(k)Â Â Â Â = d(k+31)Â Â Â Â Â Â for k = 0,1,...,297
u(k)Â Â Â Â = p(kâ298)Â Â Â Â Â for k = 298,299,...,309
u(k)    = 0                  for k = 310,311,â¦,315 (tail bits)
c)Â Â Convolutional encoder

G4 = 1 + D2Â + D3Â + D5Â + D6

C(3k+1) = u(k) + u(kâ1) + u(kâ2) + u(kâ3) + u(kâ6)
C(3k+2) = u(k) + u(kâ1) + u(k-4) + u(k-6)Â Â Â Â for k = 0,1,...,315; u(k) = 0 for k < 0
     The code is punctured depending on the value of the CPS field as defined in 3GPP TS 44.060. Three puncturing schemes named P1, P2 or P3 are applied in such a way that the following coded bits:
|
P1 |
{C(18j), C(1+18j), C(3+18j), C(6+18j),

{C(18j), C(4+18j), C(8+18j), C(11+18j),
C(12+18j), C(13+18j), C(15+18j) for j = 0,1,...,51} |
                  The result is a block of 372 coded bits, {dc(0),dc(1),...,dc(371)}.
For the FANR procedure, the code is punctured depending on the CPS field and the PANI field as defined in 3GPP TS 44.060. If the PANI field is set to 0, the puncturing is the same as for EGPRS. If the PANI field is set to 1, the puncturing schemes named P1 or P2 are applied in such a way that, in addition to the bits punctured for EGPRS, the following coded bits:
|
P1 |
{C(18j) for j = 0,1,...,51} are not transmitted except {C(k) for k = 108,342,576,810} which are transmitted |

{C(12+18j) for j = 0,1,...,51} are not transmitted except {C(k) for k = 66,390,642,876} which are transmitted |
     The result is a block of 324 coded bits {pc(0),pc(1),...,pc(323)}.

5.1.9.1.2.2Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â RTTI configurations
If the USF is sent in RTTI USF mode (see 3GPP TS 45.002) when data blocks are transmitted in RTTI configuration, then the first three bits d(0),d(1),d(2) are block coded into 36 bits uâ(0),uâ(1),...,uâ(35) as described in subclause 5.1.9.1.2.1.
If the USF is sent in BTTI USF mode (see 3GPP TS 45.002) when data blocks are transmitted in RTTI configuration, then the three bits of the USF to be sent on the lower numbered PDCH of a corresponding downlink PDCH-pair are block coded into 36 bits uL(0),uL(1),...,uL(35) as described in subclause 5.1.9.1.2.1; the three bits of the USF to be sent on the higher numbered PDCH of a corresponding downlink PDCH-pair are block coded into 36 bits uH(0),uH(1),...,uH(35) as described in subclause 5.1.9.1.2.1.
NOTE:Â Â Â Â Â If BTTI USF mode is used when sending data blocks in RTTI configuration, then d(0),d(1),d(2) need not contain a USF; in this case, they are ignored by the encoder. How the USFs are delivered to the encoder in this case is implementation dependent.
If the data block is sent in the first 10ms of a 20ms block period, then:
uâ(j)=uL(j),           j=0â¦8
uâ(j)=uH(j-9),       j=9â¦17
uâ(j)=uL(j-9),        j=18â¦26
uâ(j)=uH(j-18)      j=27â¦35
If the data block is sent in the second 10ms of a 20ms block period, then:
uâ(j)=uL(j+18),    j=0â¦8
uâ(j)=uH(j+9),      j=9â¦17
uâ(j)=uL(j+9),      j=18â¦26
uâ(j)=uH(j)                  j=27â¦35
NOTE:Â Â Â Â Â In case mixed modulation USF is used (see subclause 5.1), the USF bits sent during the other half of the 20 ms block period may be sent with a different modulation. In this case, the half of uL and uH not sent in the present data block will be discarded.
5.1.9.1.3Â Â Â Â Â Â Â Â Â Â Â Â Â Header coding
a)Â Â Parity bits:

d(3)D32Â +...+ d(27)D8Â + p(0)D7Â +...+ p(7), when divided by:
D8Â + D6Â + D3Â + 1, yields a remainder equal to:
D7Â + D6Â + D5Â + D4Â + D3Â + D2Â + D + 1.
b)Â Â Tail biting:
     The six last header parity bits are added before information and parity bits, the result being a block of 39 bits {uâ(â6),â¦,uâ(0),uâ(1),...,uâ(32)} with six negative indexes:
uâ(k-6)Â Â Â Â Â = p(k+2)Â Â Â Â Â Â Â Â for k = 0,1,...,5
uâ(k)Â Â Â Â Â Â Â Â Â = d(k+3)Â Â Â Â Â Â Â Â for k = 0,1,...,24
uâ(k)Â Â Â Â Â Â Â Â Â = p(kâ25)Â for k = 25,26,...,32
c)Â Â Convolutional encoder
     This block of 39 bits {uâ(-6),â¦,uâ(0),uâ(1),...,uâ(32)} is encoded with the 1/3 rate convolutional mother code defined by the polynomials:
G4 = 1 + D2Â + D3Â + D5Â + D6
G7 = 1 + D + D2Â + D3Â + D6
G5 = 1 + D + D4Â + D6
     This results in a block of 99 coded bits: {C(0),C(1),...,C(98)} defined by:
C(3k)Â Â Â Â = uâ(k) + uâ(kâ2) + uâ(kâ3) + uâ(kâ5) + uâ(kâ6)
C(3k+1) = uâ(k) + uâ(kâ1) + uâ(kâ2) + uâ(kâ3) + uâ(kâ6)
C(3k+2) = uâ(k) + uâ(kâ1) + uâ(kâ4) + uâ(kâ6)Â Â Â Â for k = 0,1,...,32
     A spare bit is added at the end of this block:
hc(k) = C(k) for k = 0,1,â¦,98
hc(99) = C(98)
     The result is a block of 100 coded bits, {hc(0),hc(1),...,hc(99)}.
5.1.9.1.4Â Â Â Â Â Â Â Â Â Â Â Â Â Data coding
a)Â Â Parity bits:
     Twelve data parity bits p(0),p(1),...,p(11) are defined in such a way that in GF(2) the binary polynomial:
d(28)D461Â +...+ d(477)D12Â + p(0)D11Â +...+ p(11), when divided by:
D12Â + D11Â + D10Â + D8Â + D5Â + D4Â + 1, yields a remainder equal to:
D11Â + D10Â + D9Â + D8Â + D7Â + D6Â + D5Â + D4Â + D3Â + D2Â + D + 1.
b)Â Â Tail bits:
     Six tail bits equal to 0 are added to the information and parity bits, the result being a block of 468 bits {u(0),u(1),...,u(467)}:
u(k)Â Â Â Â = d(k+28)Â Â Â Â Â Â for k = 0,1,...,449
u(k)Â Â Â Â = p(kâ450)Â Â Â Â Â for k = 450,451,...,461
u(k)    = 0                  for k = 462,463,â¦,467 (tail bits)
c)Â Â Convolutional encoder
     This block of 468 bits {u(0),u(1),...,u(467)} is encoded with the 1/3 rate convolutional mother code defined by the polynomials:
G4 = 1 + D2Â + D3Â + D5Â + D6
G7 = 1 + D + D2Â + D3Â + D6
G5 = 1 + D + D4Â + D6
     This results in a block of 1404 coded bits: {C(0),C(1),...,C(1403)} defined by:
C(3k)Â Â Â Â = u(k) + u(kâ2) + u(kâ3) + u(kâ5) + u(kâ6)
C(3k+1) = u(k) + u(kâ1) + u(kâ2) + u(kâ3) + u(kâ6)
C(3k+2) = u(k) + u(kâ1) + u(k-4) + u(k-6)Â Â Â Â for k = 0,1,...,467; u(k) = 0 for k < 0
     The code is punctured depending on the value of the CPS field as defined in 3GPP TS 44.060. Two puncturing schemes named P1 or P2 are applied in such a way that the following coded bits:
|
P1 |
{C(2+9j) for j = 0,1,...,153} as well as
{C(1388+3j) for j = 0,1,...,5}are not transmitted |
|
P2 |
{C(1+9j) for j = 0,1,...,153} as well as
{C(1387+3j) for j = 0,1,...,5}are not transmitted |
                  The result is a block of 1248 coded bits, {dc(0),dc(1),...,dc(1247)}.
For the FANR procedure, the code is punctured depending on the CPS field and the PANI field as defined in 3GPP TS 44.060. If the PANI field is set to 0, the puncturing is the same as for EGPRS. If the PANI field is set to 1, the puncturing schemes named P1 or P2 are applied in such a way that, in addition to the bits punctured for EGPRS, the following coded bits:
|
P1 |
{C(4+18j) for j = 0,1,...,76} are not transmitted except {C(k) for k = 526} which is transmitted |
|
P2 |
{C(14+18j) for j = 0,1,...,76} are not transmitted except {C(k) for k = 626} which is transmitted |

d(478)D29 +...+ d(497)D10 + p(0)D9 +...+ p(9), when divided by:
D10 + D9 + D5 + D4 + D + 1, yields a remainder equal to:
D9 + D8 + D7 + D6 + D5 + D4 + D3 + D2 + D1 + 1.
The five bits {d(498),...,d(502)} (TFI value or 00000, see 3GPP TS 44.060) are added bit-wise modulo 2 to the 5 last parity bits {p(5),â¦,p(9)}. This results in the ten modified PAN parity bits {pt(0),â¦,pt(9)} defined as:
pt(k) = p(k)                             for k=0,â¦,4
pt(k) = d(k+493) + p(k)       for k=5,â¦,9
b)Â Â Tail biting:

c)Â Â Convolutional encoder
     The block of 36 bits {uââ(-6),...,uââ(0),uââ(1),...,uââ(29)} is encoded with the 1/3 rate convolutional mother code defined by the polynomials:
G4 = 1 + D2Â + D3Â + D5Â + D6
G7 = 1 + D + D2Â + D3Â + D6
G5 = 1 + D + D4Â + D6
     This results in a block of 90 coded bits {C(0),C(1),...,C(89)} defined by:
C(3k)Â Â Â Â = uâ(k) + uâ(k-2) + uâ(k-3) + uâ(k-5) + uâ(k-6)
C(3k+1) = uâ(k) + uâ(k-1) + uâ(k-2) + uâ(k-3) + uâ(k-6)
C(3k+2) = uâ(k) + uâ(k-1) + uâ(k-4) + uâ(k-6)Â Â Â Â for k = 0,1,...,29
     The block of 90 coded bits is punctured in such way that the following coded bits:
{ C(5+6k), C(50+6k) for k = 0,1,...,6} are not transmitted.
     The result is a block of 76 coded bits {ac(0),ac(1),...,ac(75)}.
The data coded bits {pc(0),pc(1),...,pc(1171)} are appended to the PAN coded bits by the following rule:
dc(k) = ac(k)Â Â Â Â Â Â Â Â Â Â Â Â Â for k = 0,1,...,75
dc(k) = pc(k-76)Â Â Â Â Â Â for k = 76,49,...,1247
The result is a block of 1248 coded bits {dc(0),dc(1),...,dc(1247)}.
5.1.9.1.5Â Â Â Â Â Â Â Â Â Â Â Â Â Interleaving
a)Â Â Header
     The 100 coded bits of the header, {hc(0),hc(1),...,hc(99)}, are interleaved according to the following rule:
hi(j) = hc(k)Â Â Â for k = 0,1,...,99
            j = 25(k mod 4) + ((17k) mod 25)
b)Â Â Data
     There is no closed expression describing the interleaver, but it has been derived taking the following approach:
1.  A block interleaver with a 1392 bit block size is defined:
     The kth input data bit is mapped to the jth bit of the Bth burst, where
k = 0,â¦,1391
B = mod(k,4)
d = mod(k,464)
j = 3*(2mod(25d,58) + div(mod(d,8),4) + 2(-1)Bdiv(d,232)) + mod(k,3)
2.  The data bit positions being mapped onto header positions in the interleaved block are removed (the header positions are j = 156,157,â¦,191 when the header is placed next to the training sequence. This leaves 1248 bits in the mapping.
3.  The bits are renumbered to fill out the gaps both in j and k, without changing the relative order
     The resulting interleaver transform the block of 1248 coded bits, {dc(0),dc(1),...,dc(1247)} into a block of 1248 interleaved bits, {di(0),di(1),...,di(1247)}.
di(jâ) = dc(kâ) for kâ = 0,1,...,1247
(An explicit relation between jâ and kâ is given in table 15)
5.1.9.1.6Â Â Â Â Â Â Â Â Â Â Â Â Â Mapping on a burst
a)Â Â Straightforward Mapping
     The mapping is given by the rule:
     For B=0,1,2,3, let
e(B,j) = di(312B+j)Â Â Â Â Â Â Â Â for j = 0,1,...,155
e(B,j) = hi(25B+j-156)Â Â for j = 156,157,...,167
e(B,j) = uâ(9B+j-168)Â Â Â Â for j = 168,169,...,173
e(B,j) = q(2B+j-174)Â Â Â Â Â Â for j = 174,175
e(B,j) = uâ(9B+j-170)Â Â Â Â for j = 176,177,178
e(B,j) = hi(25B+j-167)Â Â for j = 179,180,...,191
e(B,j) = di(312B+j-36)Â Â for j = 192,193,...,347
     where
q(0),q(1),...,q(7) = 0,0,0,0,0,0,0,0 identifies the coding scheme MCS-5 or MCS-6.

C(3k+2) = uâ(k) + uâ(kâ1) + uâ(k-4) + uâ(k-6)Â Â Â Â for k = 0,1,...,44
     The code is punctured in such a way that the following coded bits:
{C(k) for k = 14,23,33,50,59,69,86,95,105,122,131} are not transmitted
     The result is a block of 124 coded bits, {hc(0),hc(1),...,hc(123)}.
5.1.11.1.4Â Â Â Â Â Â Â Â Â Â Â Data coding
I)Â Â First half:
a)Â Â Parity bits:
     Twelve data parity bits p(0),p(1),...,p(11) are defined in such a way that in GF(2) the binary polynomial:
d(40)D461Â +...+ d(489)D12Â + p(0)D11Â +...+ p(11), when divided by:
D12Â + D11Â + D10Â + D8Â + D5Â + D4Â + 1, yields a remainder equal to:
D11Â + D10Â + D9Â + D8Â + D7Â + D6Â + D5Â + D4Â + D3Â + D2Â + D + 1.
b)Â Â Tail bits:
     Six tail bits equal to 0 are added to the information and parity bits, the result being a block of 468 bits {u(0),u(1),...,u(467)}:
u(k)Â Â Â Â = d(k+40)Â Â Â Â Â Â for k = 0,1,...,449
u(k)Â Â Â Â = p(kâ450)Â Â Â Â Â for k = 450,451,...,461
u(k)    = 0                  for k = 462,463,â¦,467 (tail bits)
c)Â Â Convolutional encoder
     This block of 468 bits {u(0),u(1),...,u(467)} is encoded with the 1/3 rate convolutional mother code defined by the polynomials:
G4 = 1 + D2Â + D3Â + D5Â + D6
G7 = 1 + D + D2Â + D3Â + D6
G5 = 1 + D + D4Â + D6
     This results in a block of 1404 coded bits: {C(0),C(1),...,C(1403)} defined by:
C(3k)Â Â Â Â = u(k) + u(kâ2) + u(kâ3) + u(kâ5) + u(kâ6)

C(3k+2) = u(k) + u(kâ1) + u(k-4) + u(k-6)Â Â Â Â for k = 0,1,...,467; u(k) = 0 for k < 0
     The code is punctured depending on the value of the CPS field as defined in 3GPP TS 44.060. Three puncturing schemes named P1, P2 or P3 are applied in such a way that the following coded bits:
|
P1 |
{C(18j), C(1+18j), C(4+18j), C(8+18j),
C(11+18j), C(12+18j), C(13+18j), C(15+18j) |
|
P2 |
{C(2+18j), C(3+18j), C(5+18j), C(6+18j),
C(10+18j), C(14+18j), C(16+18j), C(17+18j) |

                  The result is a block of 612 coded bits, {c1(0),c1(1),...,c1(611)}.
For the FANR procedure, the code is punctured depending on the CPS field and the PANI field as defined in 3GPP TS 44.060. If the PANI field is set to 0, the puncturing is the same as for EGPRS. If the PANI field is set to 1, the puncturing schemes named P1 or P2 are applied in such a way that, in addition to the bits punctured for EGPRS, the following coded bits:
|
P1 |
{C(13+36j) for j = 0,1,â¦,38} are not transmitted except {C(k) for k = 13,49,1381} which are transmitted |
|
P2 |
{C(5+36j) for j = 0,1,â¦,38} are not transmitted except {C(k) for k = 185,545,1085} which are transmitted |
|
P3 |
{C(6+36j) for j = 0,1,â¦,38} are not transmitted except {C(k) for k = 294,654,1194} which are transmitted |
     The result is a block of 576 coded bits {pc1(0),pc1(1),...,pc1(575)}.
II)Â Second half:
     The same data coding as for first half is proceeded with bits {d(40),d(41),â¦,d(489)} replaced by bits {d(490),d(491),â¦,d(939)}. The result is a block of 612 coded bits, {c2(0),c2(1),...,c2(611)}.
     If the PANI field is set to 1, additional bits are punctured as for the first half. The result is a block of 576 coded bits {pc2(0),pc2(1),...,pc2(575)}.
5.1.11.1.4a         Piggy-backed Ack/Nack coding
The operations in this subclause shall be carried out only if a PAN field is included.
a)Â Â Parity bits
     Ten PAN parity bits p(0), p(1),...,p(9) are defined in such a way that in GF(2) the binary polynomial:
d(940)D29 +...+ d(959)D10 + p(0)D9 +...+ p(9), when divided by:
D10 + D9 + D5 + D4 + D + 1, yields a remainder equal to:
D9 + D8 + D7 + D6 + D5 + D4 + D3 + D2 + D1 + 1.
The five bits {d(960),...,d(964)} (TFI value or 00000, see 3GPP TS 44.060) are added bit-wise modulo 2 to the 5 last parity bits {p(5),â¦,p(9)}. This results in the ten modified PAN parity bits {pt(0),â¦,pt(9)} defined as:
pt(k) = p(k)                             for k=0,â¦,4
pt(k) = d(k+955) + p(k)       for k=5,â¦,9
b)Â Â Tail biting:
The six last modified PAN parity bits are added before information and modified PAN parity bits, the result being a block of 36 {uââ(-6),...,uââ(0),uââ(1),...,uââ(29)} bits with six negative indexes:
uââ(k-6) Â Â Â = pt(k+4)Â Â Â Â Â Â Â for k = 0,1,...,5
uââ(k)Â Â Â Â Â Â Â Â = d(k+940)Â Â Â Â for k = 0,1,...,19
uââ(k)Â Â Â Â Â Â Â Â = pt(k-20)Â Â Â Â Â Â for k = 20,21,...,29
c)Â Â Convolutional encoder
     The block of 36 bits {uââ(-6),...,uââ(0),uââ(1),...,uââ(29)} is encoded with the 1/3 rate convolutional mother code defined by the polynomials:
G4 = 1 + D2Â + D3Â + D5Â + D6
G7 = 1 + D + D2Â + D3Â + D6
G5 = 1 + D + D4Â + D6
     This results in a block of 90 coded bits {C(0),C(1),...,C(89)} defined by:
C(3k)Â Â Â Â = uâ(k) + uâ(k-2) + uâ(k-3) + uâ(k-5) + uâ(k-6)
C(3k+1) = uâ(k) + uâ(k-1) + uâ(k-2) + uâ(k-3) + uâ(k-6)
C(3k+2) = uâ(k) + uâ(k-1) + uâ(k-4) + uâ(k-6)Â Â Â Â for k = 0,1,...,29
     The block of 90 coded bits is punctured in such way that the following coded bits:
{ C(2+15k), C(8+15k), C(14+15k) for k = 0,1,...,5} are not transmitted.
     The result is a block of 72 coded bits {ac(0),ac(1),...,ac(71)}.
The data coded bits {pc1(0),pc1(1),...,pc1(575)} and {pc2(0),pc2(1),...,pc2(575)} are appended to the PAN coded bits by the following rule:
c1(k) = ac(k)Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â for k = 0,1,...,71
c1(k) = pc1(k-72)Â Â Â Â Â Â Â Â Â Â Â for k = 72,73,...,611
c2(k) = pc1(k+540)Â Â Â Â Â Â Â Â for k = 0,1,...,35
c2(k) = pc2(k-36)Â Â Â Â Â Â Â Â Â Â Â for k = 36,37,...,611
The result is two blocks of 612 coded bits {c1(0),c1(1),...,c1(611)} and {c2(0),c2(1),...,c2(611)}.
5.1.11.1.5Â Â Â Â Â Â Â Â Â Â Â Interleaving
a)Â Â Header
     The 124 coded bits of the header, {hc(0),hc(1),...,hc(123)}, are interleaved according to the following rule:

dc(k) = c1(k)Â Â Â Â Â Â Â Â Â Â Â Â Â for k = 0,1,...,611
dc(k) = c2(k-612)Â Â Â Â Â for k = 612,613,...,1223
     The resulting block is interleaved according to the following rule:
di(j) = dc(k)Â Â Â for k = 0,1,...,1223
            j = 306(k mod 4) + 3((44k) mod 102 + (k div 4) mod 2) + (k + 2 â (k div 408)) mod 3
5.1.11.1.6Â Â Â Â Â Â Â Â Â Â Â Mapping on a burst
a)Â Â Straightforward Mapping
     The mapping is given by the rule:
     For B=0,1,2,3, let
e(B,j) = di(306B+j)Â Â Â Â Â Â Â Â for j = 0,1,...,152
e(B,j) = hi(31B+j-153)Â Â for j = 153,154,...,167

     The result is a block of 576 coded bits {pc1(0),pc1(1),...,pc1(575)}.

5.1.12.1.4a         Piggy-backed Ack/Nack coding
The operations in this subclause shall be carried out only if a PAN field is included.
a)Â Â Parity bits
     Ten PAN parity bits p(0), p(1),...,p(9) are defined in such a way that in GF(2) the binary polynomial:
d(1132)D29 +...+ d(1151)D10 + p(0)D9 +...+ p(9), when divided by:
D10 + D9 + D5 + D4 + D + 1, yields a remainder equal to:
D9 + D8 + D7 + D6 + D5 + D4 + D3 + D2 + D1 + 1.
The five bits {d(1152),...,d(1156)} (TFI value or 00000, see 3GPP TS 44.060) are added bit-wise modulo 2 to the 5 last parity bits {p(5),â¦,p(9)}. This results in the ten modified PAN parity bits {pt(0),â¦,pt(9)} defined as:
pt(k) = p(k)                                   for k=0,â¦,4
pt(k) = d(k+1147) + p(k)           for k=5,â¦,9

uââ(k-6) Â Â Â = pt(k+4)Â Â Â Â Â Â Â Â Â Â Â Â Â for k = 0,1,...,5
uââ(k)Â Â Â Â Â Â Â Â = d(k+1132)Â for k = 0,1,...,19

     The block of 36 bits {uââ(-6),...,uââ(0),uââ(1),...,uââ(29)} is encoded with the 1/3 rate convolutional mother code defined by the polynomials:
G4 = 1 + D2Â + D3Â + D5Â + D6
G7 = 1 + D + D2Â + D3Â + D6
G5 = 1 + D + D4Â + D6
     This results in a block of 90 coded bits {C(0),C(1),...,C(89)} defined by:
C(3k)Â Â Â Â = uâ(k) + uâ(k-2) + uâ(k-3) + uâ(k-5) + uâ(k-6)
C(3k+1) = uâ(k) + uâ(k-1) + uâ(k-2) + uâ(k-3) + uâ(k-6)
C(3k+2) = uâ(k) + uâ(k-1) + uâ(k-4) + uâ(k-6)Â Â Â Â for k = 0,1,...,29
     The block of 90 coded bits is punctured in such way that the following coded bits:
{ C(2+15k), C(8+15k), C(14+15k) for k = 0,1,...,5} are not transmitted.
     The result is a block of 72 coded bits {ac(0),ac(1),...,ac(71)}.
The data coded bits {pc1(0),pc1(1),...,pc1(575)} and {pc2(0),pc2(1),...,pc2(575)} are appended to the PAN coded bits by the following rule:
c1(k) = ac(2k)Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â for k = 0,1,...,35
c1(k) = pc1(k-36)Â Â Â Â Â Â Â Â Â Â Â for k = 36,37,...,611
c2(k) = ac(2k+1)Â Â Â Â Â Â Â Â Â Â Â Â Â for k = 0,1,...,35
c2(k) = pc2(k-36)Â Â Â Â Â Â Â Â Â Â Â for k = 36,37,...,611
The result is two blocks of 612 coded bits {c1(0),c1(1),...,c1(611)} and {c2(0),c2(1),...,c2(611)}.

dc(k) = c2(k-612)Â Â Â Â Â for k = 612,613,...,1223
     The resulting block is interleaved according to the following rule:

     j = 306(2(k div 612) + (k mod 2)) + 3((74k) mod 102 + (k div 2) mod 2) + (k + 2 â (k div 204)) mod 3

The initial value of the shift registers of the 8-state constituent encoders shall be all zeros when starting to encode the input bits.

After intra-row and inter-row permutations, the bits of the permuted rectangular matrix are denoted by y'k:
                                                               
The output
of the Turbo code internal interleaver is the bit sequence read out column by
column from the intra-row and inter-row permuted R 
 C rectangular matrix starting with bit y'1
in row 0 of column 0 and ending with bit y'CR in row R
- 1 of column C - 1. The output is pruned by deleting dummy bits that were padded to the input of
the rectangular matrix before intra-row and inter row permutations, i.e. bits y'k that corresponds to bits yk with k
> K are removed from the output. The bits output from Turbo code
internal interleaver are denoted by x'1, x'2,

corresponds to the bit y'k with smallest index k
after pruning, x'2 to the bit y'k
with second smallest index k after pruning, and so on. The number of bits
output from Turbo code internal interleaver is K and the total number of

[e2_ini_p2,e2_plus_p2,e2_minus_p2] = [403,403,0]
For P1, flip=0 and T(m)=0 for every m. So, the first ten puncture pattern bits for each stream are

For stream 2 bits: 1 1 1 0 1 1 1 1 1 1

[e2_ini_p2,e2_plus_p2,e2_minus_p2] = [13,13,0]

[e2_ini_p2,e2_plus_p2,e2_minus_p2] = [234,350,0]
For P2, flip=0, and T(m) vector is the output from P1. Therefore the first ten puncture pattern bits are

The six last bits are added before the block of 30 bits, the result being a block of 36 bits {c(â6),â¦,c(0),c(1),...,c(29)} with six negative indices:
c(k)Â Â Â Â Â Â Â Â Â Â Â = b(30+k)Â Â Â Â Â Â for k = -6,...,-1
c(k)Â Â Â Â Â Â Â Â Â Â Â = b(k)Â Â Â Â Â Â Â Â Â Â Â Â Â for k = 0,1,...,29

G4 = 1 + D2Â + D3Â + D5Â + D6
G7 = 1 + D + D2Â + D3Â + D6

                  j = NCB/4 + (((k div 4)+(NC div 16)B)a mod NC/4)

5.1a.13.1Â Â Â Â Â Â Block constitution
If the message delivered to the encoder does not include a PAN, it has a fixed size of 1834 information bits {d(0),d(1),...,d(1833)}. If the message delivered to the encoder includes a PAN, it has a fixed size of 1859 information bits {d(0),d(1),...,d(1858).
NOTE:Â Â Â Â Â The presence of the PAN is indicated by the PANI field in the header (see 3GPP TS 44.060).
The message is separated into the following parts:
h(k) = d(k)Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â for k = 0,...,51
i1(k-52) = d(k)Â Â Â Â Â Â Â Â Â Â for k = 52,...,645

Each data part, {i1(0),â¦,i1(593)}, {i2(0),â¦,i2(593)} and {i3(0),â¦,i3(593)}, is coded as defined in subclause 5.1a.1.2, with N=594, resulting in three coded blocks of 1836 bits, {C1(0),...,C1(1835)}, {C2(0),...,C2(1835)} and {C3(0),...,C3(1835)}.
Each coded block is punctured depending on the value of the CPS field as defined in 3GPP TS 44.060. Three puncturing schemes named P1, P2 or P3 are applied in such a way that the following coded bits are punctured:

5.1a.19.2.2Â Â Â Â Â Â Â Â Â RTTI configurations
If the USF is sent in RTTI USF mode (see 3GPP TS 45.002) when data blocks are transmitted in RTTI configuration, then the USF bits {u(0),u(1),u(2)} are block coded into 48 bits uâ(0),uâ(1),...,uâ(47) as described in subclause 5.1a.19.2.1.
If the USF is sent in BTTI USF mode (see 3GPP TS 45.002) when data blocks are transmitted in RTTI configuration, then the three bits of the USF to be sent on the lower numbered PDCH of a corresponding downlink PDCH-pair are block coded into 48 bits uL(0),uL(1),...,uL(47) as described in subclause 5.1a.19.2.1; the three bits of the USF to be sent on the higher numbered PDCH of a corresponding downlink PDCH-pair are block coded into 48 bits uH(0),uH(1),...,uH(47) as described in subclause 5.1a.19.2.1.
NOTE:Â Â Â Â Â If BTTI USF mode is used when sending data blocks in RTTI configuration, then u(0),u(1),u(2) need not contain a USF; in this case, they are ignored by the encoder. How the USFs are delivered to the encoder in this case is implementation dependent.
If the data block is sent in the first 10ms of a 20ms block period, then:
uâ(j)=uL(j),           j=0â¦11
uâ(j)=uH(j-12),     j=12â¦23
uâ(j)=uL(j-12),     j=24â¦35
uâ(j)=uH(j-24)      j=36â¦47
If the data block is sent in the second 10ms of a 20ms block period, then:
uâ(j)=uL(j+24),    j=0â¦11
uâ(j)=uH(j+12),    j=12â¦23
uâ(j)=uL(j+12),    j=24â¦35
uâ(j)=uH(j)                  j=36â¦47
NOTE:Â Â Â Â Â In case mixed modulation USF is used (see subclause 5.1), the USF bits sent during the other half of the 20 ms block period may be sent with a different modulation. In this case, the half of uL and uH not sent in the present data block will be discarded.
5.1a.19.3Â Â Â Â Â Â Header coding
The header {h(0),...,h(37)} is coded as defined in subclause 5.1a.1.1, with N=38, resulting in a block of 138 bits, {C(0),...,C(137)}.
The code is punctured in such a way that the following coded bits:
{C(k) for k = 8 and 77} are not transmitted
This results in a block of 136 bits, {hc(0),...,hc(135)}.
5.1a.19.4Â Â Â Â Â Â Data coding
Each data part, {i1(0),â¦,i1(449)} and {i2(0),â¦,i2(449)}, is coded as defined in subclause 5.1a.1.3, with N=450, resulting in two coded blocks of 1398 bits, {C1(0),...,C1(1397)} and {C2(0),...,C2(1397)}.
Each coded block is punctured depending on the value of the CPS field as defined in 3GPP TS 44.060. Two puncturing schemes named P1 or P2 are applied.
The parameter values used for rate matching
are: swap=0, =466,=832 and =793.
P1 puncturing is generated according to 5.1a.1.3.5
P2 (Type 1) puncturing is generated according to 5.1a.1.3.5.
If a PAN is not included, the result is two blocks of 832 bits, {c1(0),...,c1(831)} and {c2(0),...,c2(831)}.
If a PAN is included, the result is two blocks of 793 bits, {c1(0),...,c1(792)} and {c2(0),...,c2(792)}.
NOTE:Â Â Â Â Â C1 and c1 correspond to i1, and C2 and c2 to i2.

a)Â Â Header
The header, {hc(0),...,hc(135)}, is interleaved as defined in subclause 5.1a.2.1, with NC=136 and a=23, resulting in a block of 136 bits, {hi(0),...,hi(135)}.
b)Â Â Data and PAN
If a PAN is not included, data are put together as one entity as described by the following rule:
dc(k) = c1(k)Â Â Â Â Â Â Â Â Â Â Â Â Â for k = 0,...,831
dc(k) = c2(k-832)Â Â Â Â Â for k = 832,...,1663
If a PAN is included, data and PAN are put together as one entity as described by the following rule:
dc(k) = ac(k)             for k = 0,â¦,77
dc(k) = c1(k-78)       for k = 78,â¦,870
dc(k) = c2(k-871)Â Â Â Â Â for k = 871,..,.1663
The block {dc(0),...,dc(1663)} is interleaved as defined in subclause 5.1a.2.1, with NC=1664 and a=199, resulting in a block of 1664 bits, {di(0),...,di(1663)}.
5.1a.19.7Â Â Â Â Â Â Mapping on a burst
a)Â Â Straightforward mapping
The mapping is given by the rule:
For B=0,1,2,3, let
e(B,j) = di(416B+j)Â Â Â Â Â Â Â Â for j = 0,...,207
e(B,j) = hi(34B+j-208)Â Â for j = 208,...,227
e(B,j) = q(2B+j-228)Â Â Â Â Â Â for j = 228,229

e(B,j) = di(416B+j-48)Â Â for j = 256,...,463
where
q(0),q(1),...,q(7) = 0,0,0,0,0,0,0,0 identifies the coding scheme DAS-8 or DAS-9.
b)Â Â Bit swapping
After this mapping the following bits are swapped:
For B = 0,1,2,3,
Swap e(B,184+k) with e(B,210+k) for k=0, 1, 4, 5, 8, 9, 12, 13, 16, 17, 20, 21.
Swap e(B,256+k) with e(B,246+k) for k=0, 1, 4, 5, 8, 9.
In RTTI configuration, the bursts with B = 0,2 shall be mapped on the PDCH having the lower timeslot number, whereas the bursts with B = 1,3 shall be mapped on the PDCH having the higher timeslot number, see 3GPP TS 45.002.

5.1a.24.2.2Â Â Â Â Â Â Â Â Â RTTI configurations
If the USF is sent in RTTI USF mode (see 3GPP TS 45.002) when data blocks are transmitted in RTTI configuration, then the USF bits {u(0),u(1),u(2)} are block coded into 32 bits uâ(0),uâ(1),...,uâ(31) as described in subclause 5.1a.24.2.1.
If the USF is sent in BTTI USF mode (see 3GPP TS 45.002) when data blocks are transmitted in RTTI configuration, then the three bits of the USF to be sent on the lower numbered PDCH of a corresponding downlink PDCH-pair are block coded into 32 bits uL(0),uL(1),...,uL(31) as described in subclause 5.1a.24.2.1; the three bits of the USF to be sent on the higher numbered PDCH of a corresponding downlink PDCH-pair are block coded into 32 bits uH(0),uH(1),...,uH(31) as described in subclause 5.1a.24.2.1.
NOTE:Â Â Â Â Â If BTTI USF mode is used when sending data blocks in RTTI configuration, then u(0),u(1),u(2) need not contain a USF; in this case, they are ignored by the encoder. How the USFs are delivered to the encoder in this case is implementation dependent.
If the data block is sent in the first 10ms of a 20ms block period, then:
uâ(j)=uL(j),           j=0â¦7
uâ(j)=uH(j-8),      j=8â¦15
uâ(j)=uL(j-8),      j=16â¦23
uâ(j)=uH(j-16)      j=24â¦31
If the data block is sent in the second 10ms of a 20ms block period, then:
uâ(j)=uL(j+16),    j=0â¦7
uâ(j)=uH(j+8),      j=8â¦15
uâ(j)=uL(j+8),      j=16â¦23
uâ(j)=uH(j)                  j=24â¦31
NOTE:Â Â Â Â Â In case mixed modulation USF is used (see subclause 5.1), the USF bits sent during the other half of the 20 ms block period may be sent with a different modulation. In this case, the half of uL and uH not sent in the present data block will be discarded.
5.1a.24.3Â Â Â Â Â Â Header coding
The header {h(0),...,h(26)} is coded as defined in subclause 5.1a.1.1, with N=27, resulting in a block of 105 bits, {C(0),...,C(104)}.
Some bits of the code are repeated in the following way:
hc(k) = C(k) for k = 0, 1, ⦠104 and
hc(105) = C(0), hc(106) = C(33), hc(107) = C(70)
This results in a block of 108 bits, {hc(0),...,hc(107)}.
5.1a.24.4Â Â Â Â Â Â Data coding
The data part, {i(0),â¦,i(449)}, is coded as defined in subclause 5.1a.1.3, with N=450, resulting in a coded block of 1398 bits, {C(0),...,C(1397)}.
The coded block is punctured depending on the value of the CPS field as defined in 3GPP TS 44.060. Two puncturing schemes named P1 or P2 are applied.
The parameter values used for rate matching
are: swap=0.05, =466,=956 and =876.
P1 puncturing is generated according to 5.1a.1.3.5
P2 (Type 1) puncturing is generated according to 5.1a.1.3.5.
If a PAN is not included, the result is a block of 956 bits, {c(0),...,c(955)}.
If a PAN is included, the result is a block of 876 bits, {c(0),...,c(875)}.

dc(k) = ac(k)             for k = 0,â¦,79
dc(k) =c(k-80)Â Â Â Â Â Â Â Â Â Â Â for k = 80,..,955
The block {dc(0),...,dc(955)} is interleaved as defined in subclause 5.1a.2.1, with NC=956 and a=173, resulting in a block of 956 bits, {di(0),...,di(955)}.

e(B,j) = hi(27B+j-120)Â Â for j = 120,...,135
e(B,j) = q(2B+j-136)Â Â Â Â Â Â for j = 136,137

e(B,j) = di(239B+j-37)Â Â for j = 157,...,275
where
q(0),q(1),...,q(7) = 0,0,0,0,0,0,0,0 identifies the coding scheme DBS-5 or DBS-6.
In RTTI configuration, the bursts with B = 0,2 shall be mapped on the PDCH having the lower timeslot number, whereas the bursts with B = 1,3 shall be mapped on the PDCH having the higher timeslot number, see 3GPP TS 45.002.

5.1a.26.2.2Â Â Â Â Â Â Â Â Â RTTI configurations
If the USF is sent in RTTI USF mode (see 3GPP TS 45.002) when data blocks are transmitted in RTTI configuration, then the USF bits {u(0),u(1),u(2)} are block coded into 64 bits uâ(0),uâ(1),...,uâ(63) as described in subclause 5.1a.26.2.1.
If the USF is sent in BTTI USF mode (see 3GPP TS 45.002) when data blocks are transmitted in RTTI configuration, then the three bits of the USF to be sent on the lower numbered PDCH of a corresponding downlink PDCH-pair are block coded into 64 bits uL(0),uL(1),...,uL(63) as described in subclause 5.1a.26.2.1; the three bits of the USF to be sent on the higher numbered PDCH of a corresponding downlink PDCH-pair are block coded into 64 bits uH(0),uH(1),...,uH(63) as described in subclause 5.1a.26.2.1.
NOTE:Â Â Â Â Â If BTTI USF mode is used when sending data blocks in RTTI configuration, then u(0),u(1),u(2) need not contain a USF; in this case, they are ignored by the encoder. How the USFs are delivered to the encoder in this case is implementation dependent.
If the data block is sent in the first 10ms of a 20ms block period, then:
uâ(j)=uL(j),           j=0â¦15
uâ(j)=uH(j-16),     j=16â¦31
uâ(j)=uL(j-16),     j=32â¦47
uâ(j)=uH(j-32)      j=48â¦63
If the data block is sent in the second 10ms of a 20ms block period, then:
uâ(j)=uL(j+32),    j=0â¦15
uâ(j)=uH(j+16),    j=16â¦31
uâ(j)=uL(j+16),    j=32â¦47
uâ(j)=uH(j)                  j=48â¦63
NOTE:Â Â Â Â Â In case mixed modulation USF is used (see subclause 5.1), the USF bits sent during the other half of the 20 ms block period may be sent with a different modulation. In this case, the half of uL and uH not sent in the present data block will be discarded.
5.1a.26.3Â Â Â Â Â Â Header coding
The header {h(0),...,h(37)} is coded as defined in subclause 5.1a.1.1, with N=38, resulting in a block of 138 bits, {C(0),...,C(137)}.
Some bits of the code are repeated in the following way:
hc(k) = C(k) for k = 0, 1, 2, ⦠137 and
hc(138) = C(0), hc(139) = C(22), hc(140) = C(49), hc(141) = C(69), hc(142) = C(91), hc(143) = C(118).
The result is a block of 144 coded bits, {hc(0),...,hc(143)}.
5.1a.26.4Â Â Â Â Â Â Data coding
Each data part, {i1(0),â¦,i1(449)} and {i2(0),â¦,i2(449)}, is coded as defined in subclause 5.1a.1.3, with N=450, resulting in two coded blocks of 1398 bits, {C1(0),...,C1(1397)} and {C2(0),...,C2(1397)}.
Each coded block is punctured depending on the value of the CPS field as defined in 3GPP TS 44.060. Two puncturing schemes named P1 or P2 are applied.
The parameter values used for rate matching
are: swap=0, =466,=996 and =956.
P1 puncturing is generated according to 5.1a.1.3.5
P2 (Type 1) puncturing is generated according to 5.1a.1.3.5.
If a PAN is not included, the result is two blocks of 996 bits, {c1(0),...,c1(995)} and {c2(0),...,c2(995)}.
If a PAN is included, the result is two blocks of 956 bits, {c1(0),...,c1(955)} and {c2(0),...,c2(955)}.
NOTE:Â Â Â Â Â C1 and c1 correspond to i1, and C2 and c2 to i2.

b)Â Â Data and PAN
If a PAN is not included, data are put together as one entity as described by the following rule:
dc(k) = c1(k)Â Â Â Â Â Â Â Â Â Â Â Â Â for k = 0,...,995
dc(k) = c2(k-996)Â Â Â Â Â for k = 996,...,1991
If a PAN is included, data and PAN are put together as one entity as described by the following rule:
dc(k) = ac(k)             for k = 0,â¦,79
dc(k) = c1(k-80)       for k = 80,â¦,1035
dc(k) = c2(k-1036)   for k = 1036,â¦,1991
The block {dc(0),...,dc(1991)} is interleaved as defined in subclause 5.1a.2.1, with NC=1992 and a=325, resulting in a block of 1992 bits, {di(0),...,di(1991)}.
5.1a.26.7Â Â Â Â Â Â Mapping on a burst
a)Â Â Straightforward mapping
The mapping is given by the rule:
For B=0,1,2,3, let
e(B,j) = di(498B+j)Â Â Â Â Â Â Â Â for j = 0,...,248
e(B,j) = hi(36B+j-249)Â Â for j = 249,...,271
e(B,j) = q(2B+j-272)Â Â Â Â Â Â for j = 272,273

e(B,j) = di(498B+j-54)Â Â for j = 303,...,551
where
q(0),q(1),...,q(7) = 0,0,0,0,0,0,0,0 identifies the coding scheme DBS-7 or DBS-8.
b)Â Â Bit swapping
After this mapping the following bits are swapped:
For B = 0,1,2,3,
Swap e(B,224+k) with e(B,250+k) for k=0, 4, 8, 12, 16, 20, 24.

5.1a.29.2.2Â Â Â Â Â Â Â Â Â RTTI configurations
If the USF is sent in RTTI USF mode (see 3GPP TS 45.002) when data blocks are transmitted in RTTI configuration, then the USF bits {u(0),u(1),u(2)} are block coded into 80 bits uâ(0),uâ(1),...,uâ(79) as described in subclause 5.1a.29.2.1.
If the USF is sent in BTTI USF mode (see 3GPP TS 45.002) when data blocks are transmitted in RTTI configuration, then the three bits of the USF to be sent on the lower numbered PDCH of a corresponding downlink PDCH-pair are block coded into 80 bits uL(0),uL(1),...,uL(79) as described in subclause 5.1a.29.2.1; the three bits of the USF to be sent on the higher numbered PDCH of a corresponding downlink PDCH-pair are block coded into 80 bits uH(0),uH(1),...,uH(79) as described in subclause 5.1a.29.2.1.
NOTE:Â Â Â Â Â If BTTI USF mode is used when sending data blocks in RTTI configuration, then u(0),u(1),u(2) need not contain a USF; in this case, they are ignored by the encoder. How the USFs are delivered to the encoder in this case is implementation dependent.
If the data block is sent in the first 10ms of a 20ms block period, then:
uâ(j)=uL(j),           j=0â¦19
uâ(j)=uH(j-20),     j=20â¦39
uâ(j)=uL(j-20),     j=40â¦59
uâ(j)=uH(j-40)      j=60â¦79
If the data block is sent in the second 10ms of a 20ms block period, then:
uâ(j)=uL(j+40),    j=0â¦19
uâ(j)=uH(j+20),    j=20â¦39
uâ(j)=uL(j+20),    j=40â¦59
uâ(j)=uH(j)                  j=60â¦79
NOTE:Â Â Â Â Â In case mixed modulation USF is used (see subclause 5.1), the USF bits sent during the other half of the 20ms block period may be sent with a different modulation. In this case, the half of uL and uH not sent in the present data block will be discarded.

Each data part, {i1(0),â¦,i1(593)}, {i2(0),â¦,i2(593)} and {i3(0),â¦,i3(593)}, is coded as defined in subclause 5.1a.1.3, with N=594, resulting in three coded blocks of 1830 bits, {C1(0),...,C1(1829)}, {C2(0),...,C2(1829)} and {C3(0),...,C3(1829)}.
Each coded block is punctured depending on the value of the CPS field as defined in 3GPP TS 44.060. Three puncturing schemes named P1, P2 or P3 are applied.
The parameter values used for rate matching
are: swap=0, =610,=833 and =807.
P1 puncturing is generated according to 5.1a.1.3.5
P2 (Type 2) puncturing is generated according to 5.1a.1.3.5.
P3 puncturing is generated according to 5.1a.1.3.5.

5.1a.31.1Â Â Â Â Â Â Block constitution
If the message delivered to the encoder does not include a PAN, it has a fixed size of 2441 information bits {d(0),d(1),...,d(2440)}. If the message delivered to the encoder includes a PAN, it has a fixed size of 2466 information bits {d(0),d(1),...,d(2465).
NOTE:Â Â Â Â Â The presence of the PAN is indicated by the PANI field in the header (see 3GPP TS 44.060).

The parameter values used for rate matching
are: swap=0, =610,=620 and =606.
P1 puncturing is generated according to 5.1a.1.3.5 using the parameters above if PAN is not included. If PAN is included in P1, then for generation of P1, N = 606 is used.
NOTE:Â Â Â Â Â When PAN is included, P1 calculated as above results in transmission of all systematic bits.
P2 (Type 2) puncturing is generated according to 5.1a.1.3.5.

5.1a.31.6Â Â Â Â Â Â Interleaving

dc4(k) = ac(4k+3)          for k = 0,â¦,13

The four blocks {dc1(0),...,dc1(619)}, {dc2(0),...,dc2(619)}, {dc3(0),...,dc3(619)} and {dc4(0),...,dc4(619)} are separately interleaved as defined in subclause 5.1a.2.2, with NC=620 and a=141, resulting in the four blocks {di1(0),â¦,di1(619)}, {di2(0),â¦,di2(619)}, {di3(0),â¦,di3(619)} and {di4(0),â¦,di4(619)}, where di1 corresponds to dc1, di2 to dc2, di3 to dc3 and di4 to dc4.

Swap e(B,141) with e(B,80)
Swap e(B,226) with e(B,110)

Swap e(B,634) with e(B,410)
5.2Â Â Â Â Â Â Â Packet control channels (PACCH, PBCCH, PAGCH, PPCH, PTCCH, CPBCCH, CPAGCH and CPPCH)
The coding scheme used for PACCH, PBCCH, PAGCH, PPCH, downlink PTCCH, CPBCCH, CPAGCH and CPPCH is the same as for CS-1 as specified in section 5.1.1.
In RTTI configuration, the channel coding for the downlink PACCH may also be the one defined for MCS-0 in subclause 5.1.4a.
The coding scheme used for uplink PTCCH is the same as for PRACH as specified in section 5.3.
5.3Â Â Â Â Â Â Â Packet random access channel (PRACH, CPRACH and MPRACH)
Two coding schemes are specified for access bursts on the packet switched channels. The packet access burst containing 8 information bits and the extended packet access burst containing 11 information bits. Only the 11 information bits access burst may be transmitted on the CPRACH.
5.3.1Â Â Â Â Â Â Packet Access Burst
The encoding of this burst is as defined in section 4.6 for the random access channel (RACH). The BSIC used shall be the BSIC of the BTS to which the burst is intended.
5.3.2Â Â Â Â Â Â Extended Packet Access Burst
The burst carrying the extended packet random access uplink message contains 11 information bits d(0),d(1),...,d(10).
Six parity bits p(0),p(1),...,p(5) are defined in such a way that in GF(2) the binary polynomial:
     d(0)D16 +...+ d(10)D6 + p(0)D5 +...+ p(5), when divided by D6 + D5 + D3 + D2 + D + 1 yields a remainder equal to D5 + D4 + D3 + D2 + D + 1.
The six bits of the BSIC, {B(0),B(1),...,B(5)}, of the BTS to which the Random Access is intended, are added bitwise modulo 2 to the six parity bits, {p(0),p(1),...,p(5)}. This results in six colour bits, C(0) to C(5) defined as C(k) = b(k) + p(k) (k = 0 to 5) where:
b(0) = MSB of PLMN colour code
b(5) = LSB of BS colour code.
This defines {u(0),u(1),..., u(20)} by:
u(k) = d(k)Â Â Â Â Â Â Â Â Â Â Â for k = 0,1,...,10
u(k) = C(kâ11)Â Â Â Â Â for k = 11,12,...,16
u(k) = 0Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â for k = 17,18,19,20 (tail bits)
The coded bits {c(0),c(1),..., c(41)} are obtained by the same convolutional code of rate ½ as for TCH/FS, defined by the polynomials:
G0 = 1 + D3Â + D4
G1 = 1 + D + D3Â + D4
and with:
c(2k) = u(k) + u(kâ3) + u(kâ4)
c(2k+1) = u(k) + u(kâ1) + u(kâ3) + u(kâ4)Â Â Â Â Â Â Â for k = 0,1,...,20 ; u(k) = 0 for k < 0
The code is punctured in such a way that the following coded bits:
c(0), c(2), c(5), c(37), c(39), c(41) are not transmitted.
This results in a block of 36 coded bits, {e(0), e(1),...,e(35)}.
5.4Â Â Â Â Â Â Â Access Burst on packet switched channels other than PRACH, CPRACH and MPRACH
The encoding of this burst is as defined in section 5.3 for the packet random access channel (PRACH). The BSIC used shall be the BSIC of the BTS to which the burst is intended.

6.1Â Â Â Â Â Â Â General
Data stream from higher layers (transport blocks) is encoded to offer transport services over the radio transmission link. The coding/multiplexing unit of FLO is a combination of error detection, forward error correction, rate matching, multiplexing, interleaving and burst mapping onto basic physical subchannel.
6.2Â Â Â Â Â Â Â Transport channel coding/multiplexing
On transport channels, data arrives to the coding/multiplexing unit in form of transport blocks (TB) once every transmission time interval (TTI).
The following coding/multiplexing steps can be identified:
-Â Â Â Â add CRC to each transport block (see subclause 6.2.1);
-Â Â Â Â channel coding (see subclause 6.2.2);
-Â Â Â Â rate matching (see subclause 6.2.3);
-Â Â Â Â multiplexing of transport channels (see subclause 6.2.4);
-Â Â Â Â TFCI encoding (see subclause 6.2.5);
-Â Â Â Â (downlink only) mapping of in-band signalling bits (see subclause 6.2.6);
-Â Â Â Â radio packet mapping (see subclause 6.2.7);
-Â Â Â Â interleaving (see subclause 6.2.8);
-Â Â Â Â mapping on a burst (see subclause 6.2.9).
The coding/multiplexing steps are shown in figure 3 below.
Figure 3: Transport channel coding/multiplexing
6.2.1Â Â Â Â Â Â CRC Attachment
Error detection is provided on transport blocks through a Cyclic Redundancy Check (CRC). The size of the CRC to be used is 18, 12, 6 or 0 bits and it is configured by higher layers for each TrCH.
Transport blocks are delivered to the CRC
attachment block. They are denoted by 
 where
i is the TrCH number and Di is the number of bits in
the transport block.
The whole transport block is used to calculate the CRC parity bits. The parity bits are generated by one of the following cyclic generator polynomials:
-Â Â Â Â gCRC18(D) = D18 + D17 + D14 + D13 + D11 + D10 + D8 + D7 + D6 + D3 + D2 + 1Â Â same as for SACCH/TP
-Â Â Â Â gCRC12(D) = D12 + D11 + D10 + D8 + D5 + D4 + 1Â Â Â same as for MCS-1
-Â Â Â Â gCRC6(D) = D6 + D5 + D3 + D2 + D1 + 1Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â same as for TCH/AFS
Denote the parity bits by 
. Li is the number
of parity bits (size of the CRC) and can take the values 18, 12, 6, or 0.
The encoding is performed in a systematic form, which means that in GF(2), the polynomial:
-Â Â Â Â when divided by gCRC18 yields a remainder equal to:
1 + D + D2 + D3 + D4 + D5 + D6 + D7 + D8 + D9 + D10 + D11 + D12 + D13 + D14 + D15 + D16 + D17
-Â Â Â Â when divided by gCRC12 yields a remainder equal to:
1 + D + D2 + D3 + D4 + D5 + D6 + D7 + D8 + D9 + D10 + D11 + D12
-Â Â Â Â when divided by gCRC6 yields a remainder equal to:
1 + D + D2 + D3 + D4 + D5
The result of CRC attachment is a code
block of Ui bits 
 where:
                      for k = 1,2,3,â¦, Di
     for k = Di+1,
Di+2,â¦, Di+Li
If no transport blocks are input to the CRC calculation, no CRC attachment shall be done.
6.2.2Â Â Â Â Â Â Channel Coding
Code blocks are delivered to the channel
coding block. They are denoted by  where i
is the TrCH number and Ui is the number of bits in the code
block. After channel coding the bits are denoted by 
(encoded
blocks) where Ci is the number of encoded bits.
Before convolutional coding 6 tail bits with binary value 0 are added to the end of the code block:
The block is then encoded with the same 1/3 rate convolutional code as for MCS-1, defined by the following polynomials:
G4 = 1 + D2Â + D3Â + D5Â + D6
G7 = 1 + DÂ + D2Â + D3Â + D6
G5 = 1 + DÂ + D4Â + D6
resulting in an encoded block of Ci
bits {} with:
 ;
 ;
 for k
= 0,1,â¦, Ui + 5 and ui,k = 0 for k <
1.
6.2.3Â Â Â Â Â Â Rate Matching
Rate matching means that bits of an encoded block on a transport channel are repeated or punctured. The number of bits on a transport channel can vary between different transmission time intervals. When the number of bits between different transmission time intervals is changed, bits are repeated or punctured to ensure that the total bit rate after TrCH multiplexing is identical to the total channel bit rate of the allocated dedicated basic physical subchannel.
Higher layers assign a rate-matching attribute to each transport channel. The rate matching attribute is used to calculate the number of bits to be repeated or punctured.
The input bit sequences before rate
matching (encoded blocks) are denoted by  where
i is the TrCH number and Ci is the number of bits.
Only one radio frame per TrCH is delivered to the rate matching block.
Notation used:
       Round x towards -¥, i.e. integer
such that 
.
         Absolute value of x.
 I             Number of TrCHs in the coded composite transport channel (CCTrCH).
   Total number of bits that are
available in a radio packet for the CCTrCH.
     Number of bits in an encoded
block before rate matching on TrCH i with transport format combination j.
   If positive,  denotes the number of bits that have
to be repeated in an encoded block on TrCH i with transport format
combination j in order to produce a radio frame.
               If
negative, denotes the number of bits
that have to be punctured in an encoded block on TrCH i with transport
format combination j in order to produce a radio frame.
               If null, no bits have to be punctured nor repeated, i.e. the rate matching is transparent and the content of the radio frame is identical to the content of the encoded block on TrCH i with transport format combination j.
    Semi-static rate matching
attribute for transport channel i.
 eini        Initial value of variable e in the rate matching pattern determination algorithm.
 eplus      Increment of variable e in the rate matching pattern determination algorithm.
 eminus    Decrement value of variable e in the rate matching pattern determination algorithm.
      Intermediate calculation variable.
RÂ Â Â Â Â Â Â Â Â Â Â Â Redundancy pattern index used for the transmission of signalling transport blocks on half rate channels (see subclause 6.2.10). In all other cases R = 0.
For each radio packet using transport format combination j, the number of bits to be repeated or punctured DNi,j within one encoded block for each TrCH i is calculated with the following equations:
   for all i = 1 ⦠I
 for all i = 1 ⦠I
For the calculation of the rate matching pattern of each TrCH i the following relations are defined:
eplus =
eminusÂ
= 
if  < 0 Â
if 
                                --
average distance between punctured bits
else
     --
average distance between transmitted bits
     
end if
else eini = 1
end if.
The rate matching rule is as follows:
if  < 0 Â
                       -- puncturing is to be performed
e = eini                               -- initial error between current and desired puncturing ratio
m = 1Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â -- index of current bit
do while 
            --
for each bit of the encoded block of TrCHi
e = e â eminus              -- update error
if 
 then            --
check if bit number m should be punctured
puncture bit bim  -- bit is punctured
e = e + eplus         -- update error
end if
m = m + 1Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â --Â next bit
end do
else if  > 0                  --
repetition is to be performed
e = eini                               -- initial error between current and desired puncturing ratio
m = 1Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â -- index of current bit
do while             --
for each bit of the encoded block of TrCHi
e = e â eminus              -- update error
do while         --
check if bit number m should be repeated
repeat bit bi,m      -- repeat bit
e = e + eplus         -- update error
end do
m = m + 1Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â --Â next bit
end do
else                                           --
 = 0Â
do nothing                        -- no repetition nor puncturing
end if.
For each TrCH i, the bit sequences
output from the rate matching are denoted 
,
where i is the TrCH number and Vi is the number of
bits in the radio frame of TrCH i (
).
6.2.4Â Â Â Â Â Â Transport Channel multiplexing
For every transmitted radio packet, one radio frame from each active TrCH is delivered to the TrCH multiplexing. These radio frames are serially multiplexed into a coded composite transport channel (CCTrCH).
The input bit sequences to the TrCH
multiplexing are denoted by  where i
is the TrCH number and Vi is the number of bits in the radio
frame of TrCH i. If TrCHi is inactive, Vi
= 0. The number of TrCHs is denoted by I. The bits output from TrCH
multiplexing are denoted 
 where Ndata
is the total number of bits that are available in a radio packet for the
CCTrCH, i.e. 
.
The TrCH multiplexing is defined by the following relations:
                for
k = 1,2,â¦,V1
        for
k = V1 + 1,V1 + 2,â¦, V1
+ V2
â¦

k = (V1 + V2 + ⦠+ VI-1) + 1, (V1 + V2

+ V2 + ⦠+ VI-1) + VI
NOTE: Â Â Â Â when I = 1, the TrCH multiplexing block is transparent for the only radio frame of the only transport channel i and consequently the output bit sequence is identical to the input one.
6.2.5 Â Â Â Â Â TFCI Encoding
The TFCI informs the receiver about the transport format combination of the CCTrCH. As soon as the TFCI is detected, the transport format combination, and hence the transport formats of the individual transport channels are known. The size and values of the TFCI to be used on basic physical subchannels are configured by higher layers. The value of the TFCI can vary between different transmission time intervals. The size of the TFCI can only be changed through higher layer signalling.
The TFCI bit
sequence is denoted by 
 with
.
The TFCI information bits are first block
coded. The coded TFCI bit sequence is denoted by 
 with 
. The block coding is done according
to the following rules:
On GMSK full rate channels and 8PSK half rate channels, the coding of the TFCI shall be as follows:
-Â Â Â Â 1 bit TFCI shall be encoded to 8 bits according to Table 25;
-Â Â Â Â 2 bits TFCI shall be encoded to 16 bits according to Table 24;
-Â Â Â Â 3 bits TFCI shall be encoded to 24 bits according to Table 23;
-Â Â Â Â 4 bits TFCI shall be encoded to 28 bits according to Table 22;
-Â Â Â Â 5 bits TFCI shall be encoded to 36 bits according to Table 21.
On 8PSK full rate channels, the coding of the TFCI shall be obtained by repetition of the coding defined for GMSK full rate channels:
-Â Â Â Â 1 bit TFCI shall be encoded to 16 bits (concatenation of two identical coded sequences of 8 bits);
-Â Â Â Â 2 bits TFCI shall be encoded to 32 bits (concatenation of two identical coded sequences of 16 bits);
-Â Â Â Â 3 bits TFCI shall be encoded to 48 bits (concatenation of two identical coded sequences of 24 bits);
-Â Â Â Â 4 bits TFCI shall be encoded to 56 bits (concatenation of two identical coded sequences of 28 bits);
-Â Â Â Â 5 bits TFCI shall be encoded to 72 bits (concatenation of two identical coded sequences of 36 bits).
On GMSK half rate channels, the coding of the TFCI shall be obtained by using only the middle segment of the coding defined for GMSK full rate channels:
-Â Â Â Â 1 bit TFCI shall be encoded to 4 bits;
-Â Â Â Â 2 bits TFCI shall be encoded to 8 bits;
-Â Â Â Â 3 bits TFCI shall be encoded to 12 bits;
-Â Â Â Â 4 bits TFCI shall be encoded to 14 bits;
-Â Â Â Â 5 bits TFCI shall be encoded to 18 bits.
6.2.6Â Â Â Â Â Â In-band signalling encoding
The in-band signalling
bits are transmitted in the downlink direction only. The information contained
in these bits is a TFCI sequence 
. The number of in-band signalling bits in each
radio packet, NTFCIU, is equal to the size of the uplink TFCI. The number of coded in-band signalling bits in
each radio packet, NCINBAND, is equal to the size of the coded uplink TFCI (see
subclause 6.2.5).
The coded in-band
signalling bit sequence is denoted 
.
6.2.7Â Â Â Â Â Â Radio packet mapping
The input data bit sequence is denoted by  where NdataÂ
is the total number of bits that are available in a radio packet for the
CCTrCH. After mapping on a radio packet the bits are denoted by 
 where Nradio is
the total number of bits that are available in a radio packet:
On GMSK full rate channels, Nradio = 464;
On GMSK half rate channels, Nradio = 232;
On 8PSK full rate channels, Nradio = 1392;
On 8PSK half rate channels, Nradio = 696.
The result of the radio packet mapping is a
radio packet of Nradio bits {}
where:
-Â Â Â Â in the uplink:
                       for k = 0,1,2,â¦, NCTFCI
â 1
           for k = NCTFCI,
NCTFCI + 1, â¦, Nradio â 1
-Â Â Â Â in the downlink:
                                     for k
= 0,1,2,â¦,NCTFCI â 1
                         for k = NCTFCI, NCTFCI
+ 1, â¦, NCTFCI + NCINBAND â 1
          for k = NCTFCI + NCINBAND,
NCTFCI + NCINBAND + 1, â¦, Nradio
â1
6.2.8Â Â Â Â Â Â Interleaving
The interleaving type (block rectangular,
block diagonal) and interleaving depth are configured by higher layers. The input bit sequence to the interleaving is denoted by 
 where Nradio
is the total number of bits that are available in a radio packet. Interleaved
bits are noted i(B,jk) where B denotes the burst number and jk
the position of the bit within the burst.
The interleaving for the nth radio packet is based on the following equations:
i(B,jk) = hk     for k = 0,1,2, â¦Nradio-1
n = 0,1,â¦,N,N+1,â¦
for block diagonal interleaving:
if  a > 1  Â
then 
else s = 0
for block rectangular interleaving:
 if  Â
a > 1Â Â then
else s = 0
where:
jk   is the position of the bit k within the burst B;
D Â is the interleaving depth in bursts;
J Â Â is the burst size in bits (J = Nradio / M);
MÂ Â is the size of the radio packet in bursts (M = 4 for full rate channels, M = 2 for half rate channels);
GCD(m,n) is the greatest common divisor of m and n.
On 8PSK channels, bit swapping for the coded bits of the TFCI is performed:
cpt = 0Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â -- counter of the swapped bits
for k = 0,1,2,3,â¦,NCTFCI - 1
if 
                           --
the coded bit is to be mapped on a weak bit of the 8PSK symbol
cpt = cpt + 1Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â -- increment the counter of swapped bits
if 
Â
Swap bit hk with bit hk+80
else
Swap bit hk with bit 
end if
end if
The value of Nradio is specified in subclause 6.2.7. On GMSK channels J = 116, whereas on 8PSK channels J = 348.
For diagonal interleaving over 40 ms (used on full rate channels), D = 8. The result of the interleaving is then a distribution of the reordered bits over 8 bursts, using the even numbered position of the first 4 bursts and the odd positions of the last 4 bursts.
For diagonal interleaving over 4 bursts (used on half rate channels), D = 4. The result of the interleaving is then a distribution of the reordered bits over 4 bursts, using the even numbered position of the first 2 bursts and the odd positions of the last 2 bursts.
For diagonal interleaving over 60 ms (used on full rate channels), D = 12. The result of the interleaving is then a distribution of the reordered bits over 12 bursts, allocating one third of the bits to each of three consecutive radio packets.
For diagonal interleaving over 60 ms (used on half rate channels), D = 6. The result of the interleaving is then a distribution of the reordered bits over 6 bursts, allocating one third of the bits to each of three consecutive radio packets.
For block rectangular interleaving over 20 ms (used on full rate channels), D = 4. The result of the interleaving is the distribution of the reordered bits over 2´D = 8 blocks as in the case of block diagonal interleaving over 8 bursts, and the first 4 blocks are combined with the last 4 blocks: block 0 is combined with block 4, block 1 is combined with block 5, block 2 is combined with block 6, block 3 is combined with block 7.
Block diagonal interleaving over 60 ms shall be used for 8PSK modulation only.
6.2.9Â Â Â Â Â Â Mapping on a Burst
The mapping is given by the rule:
e(B,j)  = i(B,j)     for j = 0,1,â¦,115 on GMSK channels;
                               for j = 0,1,â¦,347 on 8PSK channels.
NOTE:Â Â Â Â Â No stealing flags are used with FLO.

6.2.10Â Â Â Signalling on Half Rate Channels
When a signalling transport block is sent on half rate channels, the value of the redundancy pattern index (R) to be used in rate matching is given by the TDMA frame number (see 3GPP TS 45.002) of the first burst carrying coded bits of the corresponding radio packet, and table 26 below.
