5 Channel coding, multiplexing and interleaving

Data and control streams from/to MAC layer are encoded /decoded to offer transport and control services over the radio transmission link. Channel coding scheme is a comination of error detection, error correcting, rate matching, interleaving and transport channel or control information mapping onto/splitting from physical channels.

5.1 Generic procedures

This section contains coding procedures which are used for more than one transport channel or control information type.

5.1.1 CRC calculation

Denote the input its to the CRC computation y , and the parity its y . A is the size of the input sequence and L is the numer of parity its. The parity its are generated y one of the following cyclic generator polynomials:

- gCRC24A(D) = [D²⁴ + D²³ + D¹⁸ + D¹⁷ + D¹⁴ + D¹¹ + D¹⁰ + D⁷ + D⁶ + D⁵ + D⁴ + D³ + D + 1] and;

- gCRC24B(D) = [D²⁴ + D²³ + D⁶ + D⁵ + D + 1] for a CRC length L = 24 and;

- gCRC16(D) = [D¹⁶ + D¹² + D⁵ + 1] for a CRC length L = 16.

- gCRC8(D) = [D⁸ + D⁷ + D⁴ + D³ + D + 1] for a CRC length of L = 8.

The encoding is performed in a systematic form, which means that in GF(2), the polynomial:

yields a remainder equal to 0 when divided y the corresponding length-24 CRC generator polynomial, gCRC24A(D) or gCRC24B(D), the polynomial:

yields a remainder equal to 0 when divided y gCRC16(D), and the polynomial:

yields a remainder equal to 0 when divided y gCRC8(D).

The its after CRC attachment are denoted y , where B = A+ L. The relation etween ak and k is:

for k = 0, 1, 2, , A-1

for k = A, A+1, A+2,..., A+L-1.

5.1.2 Code lock segmentation and code lock CRC attachment

The input it sequence to the code lock segmentation is denoted y , where B > 0. If B is larger than the maximum code lock size Z, segmentation of the input it sequence is performed and an additional CRC sequence of L = 24 its is attached to each code lock. The maximum code lock size is:

- Z = 6144.

If the numer of filler its F calculated elow is not 0, filler its are added to the eginning of the first lock.

Note that if B < 40, filler its are added to the eginning of the code lock.

The filler its shall e set to <NULL> at the input to the encoder.

Total numer of code locks C is determined y:

if

L = 0

Numer of code locks:

else

L = 24

Numer of code locks: .

end if

The its output from code lock segmentation, for C&nsp&nsp0, are denoted y , where r is the code lock numer, and Kr is the numer of its for the code lock numer r.

Numer of its in each code lock (applicale for C  0 only):

First segmentation size: = minimum K in tale 5.1.3-3 such that

if

the numer of code locks with length is =1, ,

else if

Second segmentation size: = maximum K in tale 5.1.3-3 such that

Numer of segments of size : .

Numer of segments of size : .

end if

Numer of filler its:

for k = 0 to F-1 -- Insertion of filler its

end for

k = F

s = 0

for r = 0 to C-1

if

else

end if

while

end while

if C >1

The sequence is used to calculate the CRC parity its according to suclause 5.1.1 with the generator polynomial gCRC24B(D). For CRC calculation it is assumed that filler its, if present, have the value 0.

end while

end if
