3	Definitions, symbols and abbreviations
3.1	Definitions
For the purposes of the present document, the terms and definitions given in TR 21.905 [x] and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905 [1].
Ancillary equipment: Equipment (apparatus), used in connection with a receiver, transmitter or transceiver is considered as an ancillary equipment (apparatus) if:
-	the equipment is intended for use in conjunction with a receiver, transmitter or transceiver to provide additional operational and/or control features to the radio equipment, (e.g. to extend control to another position or location); and
-	the equipment cannot be used on a stand alone basis to provide user functions independently of a receiver, transmitter or transceiver; and
-	the receiver, transmitter or transceiver to which it is connected, is capable of providing some intended operation such as transmitting and/or receiving without the ancillary equipment (i.e. it is not a sub‑unit of the main equipment essential to the main equipment basic functions).
Base Station equipment: Radio and/or ancillary equipment intended for operation at a fixed location and powered directly or indirectly (e.g. via an AC/DC converter or power supply) by AC mains network, or an extended local DC mains network.

NOTE:	A Base Station where receiver or transmitter processes carriers of different RATs simultaneously, but not through common active RF components, is not an MSR BS according to the above definition. Such a BS is in the present specification referred to as “other BS supporting more than one RAT”.
Radio communications equipment : Telecommunications equipment which includes one or more transmitters and/or receivers and/or parts thereof for use in a fixed, mobile or portable application. It can be operated with ancillary equipment but if so, is not dependent on it for basic functionality.
Radio equipment: Equipment which contains Radio digital unit and Radio unit.
Radio digital unit: Equipment which contains base band and functionality for controlling Radio unit.
Radio unit: Equipment which contains transmitter and receiver.
Port: A particular interface, of the specified equipment (apparatus), with the electromagnetic environment. For example, any connection point on an equipment intended for connection of cables to or from that equipment is considered as a port (see Figure 3.1.1).
Receiver exclusion band: The receiver exclusion band is the band of frequencies over which no tests of radiated immunity of a receiver are made. The exclusion band for receivers is expressed relative to the base station receive band.
Signal and control: Port which carries information or control signals, excluding antenna ports.
Telecommunication port: Ports which are intended to be connected to telecommunication networks (e.g. public switched telecommunication networks, integrated services digital networks), local area networks (e.g. Ethernet, Token Ring) and similar networks.
Throughput: The number of payload bits successfully received per second for a reference measurement channel in a specified reference condition.
Transient phenomena: Pertaining to or designating a phenomena or a quantity which varies between two consecutive steady states during a time interval short compared with the time-scale of interest (IEC 60050-161 [14]).
Transmitter exclusion band: The transmitter exclusion band is the band of frequencies over which no tests of radiated immunity of a transmitter are made. The exclusion band for transmitters is expressed relative to the carrier frequencies used (the carrier frequencies of the base stations activated transmitter(s).)
Upper RF bandwidth edge: The frequency of the upper edge of the Base Station RF bandwidth, used as a frequency reference point for transmitter and receiver requirements

4	Test conditions
4.1	General
The equipment shall be tested in normal test environment defined in base station conformance testing specification TS 37.141 [11]. The test conditions shall be recorded in the test report.
For an EUT which contains more than one BS, it is sufficient to perform tests relating to ports of each representative type of the BS forming part of the EUT. For an MSR BS or other BS supporting more than one RAT, tests shall be performed relating to each port, but need not be repeated for each RAT that use the same port unless the test configuration in subclause 4.5 calls for a multi-RAT test configuration. For other BS supporting more than one RAT however (other than MSR BS), tests relating to the antenna port(s) shall always be performed for each supported RAT.
The manufacturer shall declare the supported operating band(s) according to subclause 4.4 of TS 37.141 [11]. Requirements apply only for the declared operating band and corresponding Band Category.
The manufacturer shall declare the supported capability set(s) according to subclause 4.7 of TS 37.141 [11]. Tests performed on a Base Station according to a declared Capability Set cover all single RAT and multi-RAT configurations included in the declared Capability Set. 
4.2	Arrangements for establishing a communication link
The wanted RF signal nominal frequency shall be selected by setting the channel number according to the following:
-	The Absolute Radio Frequency Channel Number (EARFCN) for E-UTRA carrier
-	The Absolute Radio Frequency Channel Number (UARFCN) for UTRA carrier 
-	The Absolute Radio Frequency Channel Number (ARFCN) for GSM/EDGE carrier
A communication link shall be set up with a suitable test system capable of evaluating the required performance criteria (hereafter called "the test system") at the radio interface and telecommunication port/ports (the S1/Iub/Abis interface). The test system shall be located outside of the test environment.
When the EUT is required to be in the transmit/receive mode, the following conditions shall be met:
-	The EUT shall be commanded to operate at maximum rated transmit power;
-	Adequate measures shall be taken to avoid the effect of the unwanted signal on the measuring equipment;
-	The wanted RF input signal level shall be set to a level where the performance is not limited by the receiver noise floor or strong signal effects.
-	For E-UTRA, the wanted signal can be set e.g. 15 dB above the reference sensitivity level as defined in TS 36.141 [9] to provide a stable communication link.
-	For UTRA FDD and TDD, the wanted signal can be set e.g. 15 dB above the reference sensitivity level as defined in TS 25.141 [7] or TS 25.142 [8] respectively, to provide a stable communication link.
-	For GSM/EDGE the wanted receiver input signal level shall be set to a nominal value of -47 dBm.
For immunity tests subclause 4.3 shall additionally apply.
4.2.1	Multiple enclosure BS solution
For a BS with multiple enclosures, the BS part with Radio digital unit and the Radio unit may be tested separately. Communication link shall be set up in the same way as if they are in single BS enclosure. The Radio Digital unit and the Radio unit shall communicate over an interface enabling establishment of a communication link.
4.3	Narrow band responses on receivers
Responses on receivers or duplex transceivers occurring during the immunity test at discrete frequencies which are narrow band responses (spurious responses), are identified by the following method:
-	if during an immunity test the quantity being monitored goes outside the specified tolerances (clause 6), it is necessary to establish whether the deviation is due to a narrow band response or to a wide band (EMC) phenomenon. Therefore, the test shall be repeated with the unwanted signal frequency first increased, and then decreased by an offset foffset, where
-	For E-UTRA, foffset = 2 x BWChannel, where BWChannel is the channel bandwidth as defined in TS 36.104 [9];
-	For UTRA, foffset = 10 MHz
-	For GSM/EDGE, foffset = 400 kHz
-	if the deviation disappears in either or both of the above offset cases, then the response is considered as a narrow band response;
-	if the deviation does not disappear, this may be due to the fact that the offset has made the frequency of the unwanted signal correspond to the frequency of another narrow band response. Under these circumstances the procedure is repeated with the increase and decrease of the frequency of the unwanted signal set to 1.25 x foffset;
-	if the deviation does not disappear with the increased and/or decreased frequency, the phenomenon is considered wide band and therefore an EMC problem and the equipment fails the test.
Narrow band responses are disregarded.
4.4	Exclusion bands
An exclusion band is a band of frequencies over which no tests of radiated immunity are made.
4.4.1	Transmitter exclusion band
For testing of radiated immunity there shall be no transmitter exclusion band. 
4.4.2	Receiver exclusion band
The receiver exclusion band for base stations extends from the lower frequency of the Base Station receive band minus 20 MHz to the upper frequency of the Base Station receive band plus 20 MHz. The exclusion bands for the MSR, E-UTRA, UTRA and GSM/EDGE paired and unpaired operating bands are as set out in Tables 4.4-2 and 4.4-3 respectively.

6.1	Performance criteria for continuous phenomena for BS
6.1.1	E-UTRA performance criteria
The throughput in Table 6.1.1-1 is stated relative to the maximum throughput of the FRC. The maximum throughput for an FRC is equal to the payload size * the number of uplink subframes per second.
The BS Uplink and Downlink paths shall each meet the performance criteria defined in Table 6.1.1-1 during the test. If the Uplink and Downlink paths are evaluated as a one loop then the criteria is two times the throughput reduction shown in Table 6.1.1-1.

8	Emission
8.1	Test configurations
This subclause defines the configurations for emission tests as follows:
-	the equipment shall be tested under normal test conditions as specified in the functional standards;
-	the test configuration shall be as close to normal intended use as possible;
-	if the equipment is part of a system, or can be connected to ancillary equipment, then it shall be acceptable to test the equipment while connected to the minimum configuration of ancillary equipment necessary to exercise the ports;
-	if the equipment has a large number of ports, then a sufficient number shall be selected to simulate actual operation conditions and to ensure that all the different types of termination are tested;
-	the test conditions, test configuration and mode of operation shall be recorded in the test report;
-	ports which in normal operation are connected shall be connected to an ancillary equipment or to a representative piece of cable correctly terminated to simulate the input/output characteristics of the ancillary equipment, Radio Frequency (RF) input/output ports shall be correctly terminated;
-	ports which are not connected to cables during normal operation, e.g. service connectors, programming connectors, temporary connectors etc. shall not be connected to any cables for the purpose of EMC testing. Where cables have to be connected to these ports, or interconnecting cables have to be extended in length in order to exercise the EUT, precautions shall be taken to ensure that the evaluation of the EUT is not affected by the addition or extension of these cables;
-	the test arrangements for transmitter and receiver sections of the transceiver are described separately for the sake of clarity. However, where possible the test of the transmitter section and receiver section of the EUT may be carried out simultaneously to reduce test time.
8.2	Radiated emission from Base Station and ancillary equipment
8.2.1	Radiated emission for Base Stations
This test is applicable to Base stations, except for BS that are only single-RAT GSM/EDGE capable. This test shall be performed on a representative configuration of the Base station.
For Base Stations that are only single-RAT GSM/EDGE capable, the test method and limits in clause 8 of TS 51.021 [10] apply.
8.2.1.1	Definition
This test assesses the ability of BS to limit unwanted emission from the enclosure port.
8.2.1.2	Test method
a)	A test site fulfilling the requirements of ITU-R SM. 329 [15] shall be used. The BS shall be placed on a non-conducting support and shall be operated from a power source via a RF filter to avoid radiation from the power leads. 
	Mean power of any spurious components shall be detected by the test antenna and measuring receiver (e.g. a spectrum analyser). At each frequency at which a component is detected, the BS shall be rotated and the height of the test antenna adjusted to obtain maximum response, and the effective radiated power (e.r.p.) of that component determined by a substitution measurement. The measurement shall be repeated with the test antenna in the orthogonal polarization plane.
NOTE:	Effective radiated power (e.r.p.) refers to the radiation of a half wave tuned dipole instead of an isotropic antenna. There is a constant difference of 2,15 dB between e.i.r.p. and e.r.p.
e.r.p. (dBm) = e.i.r.p. (dBm) − 2,15			Ref: ITU-R SM.329 ANNEX 1 [15].
b)	The BS shall transmit with maximum power declared by the manufacturer with all transmitters active. Set the base station to transmit a signal as stated in subclause 4.5.
c)	The received power shall be measured over the frequency range 30 MHz to 12.75 GHz, excluding 10 MHz below the lower RF bandwidth edge to 10 MHz above the upper RF bandwidth edge The measurement bandwidth shall be 100 kHz between 30 MHz and 1 GHz and 1 MHz above 1 GHz as given in ITU-R SM.329 [15]. The video bandwidth shall be approximately three times the resolution bandwidth. If this video bandwidth is not available on the measuring receiver, it shall be the maximum available and at least 1 MHz. Unless otherwise stated, all measurements are done as mean power (RMS).
8.2.1.3	Limits
The frequency boundary and reference bandwidths for the detailed transitions of the limits between the requirements for out of band emissions and spurious emissions are based on ITU-R Recommendations SM.329 [10] and SM.1539 [23].
The BS shall meet the limits below:
Table 8.2.1.3-1: Limits for radiated emissions from BS 
Frequency range
Minimum requirement (e.r.p.)/Reference Bandwidth
30 MHz≤ f <1000 MHz
-36 dBm/100 kHz

FBW RF,low :		Lower RF bandwidth edge
 
8.2.1.4	Interpretation of the measurement results
The interpretation of the results recorded in a test report for the radiated emission measurements described in the present document shall be as follows:
-	the measured value related to the corresponding limit will be used to decide whether an equipment meets the requirements of the present document;
-	the value of the measurement uncertainty for the measurement of each parameter shall be included in the test report;
-	the recorded value of the measurement uncertainty shall be, for each measurement, equal to or lower than the figures in Table 8.2.1-4-1 for BS.
Table 8.2.2 specifies the Maximum measurement uncertainty of the Test System. The Test System shall enable the equipment under test to be measured with an uncertainty not exceeding the specified values. All tolerances and uncertainties are absolute values, and are valid for a confidence level of 95 %, unless otherwise stated.
A confidence level of 95% is the measurement uncertainty tolerance interval for a specific measurement that contains 95% of the performance of a population of test equipment.

*NOTE: This value may be reduced to ±6 dB when further information on the potential radiation characteristic of the EUT is available.

NOTE:	If the Test System for a test is known to have a measurement uncertainty greater than that specified in Table 8.2.2, this equipment can still be used, provided that an adjustment is made follows:
	Any additional uncertainty in the Test System over and above that specified in Table 8.2.1.4-1 is used to tighten the Test Requirements - making the test harder to pass. This procedure will ensure that a Test System not compliant with Table 8.2.1.4-1 2 does not increase the probability of passing an EUT that would otherwise have failed a test if a Test System compliant with Table 8.2.1.4-1 had been used. 
8.2.2	Radiated emission, ancillary equipment
This test is applicable to ancillary equipment. This test shall be performed on a representative configuration of the ancillary equipment.
8.2.2.1	Definition
