5 General test conditions and declarations
25.1423GPPBase Station (BS) conformance testing (TDD)Release 17TS
Many of the tests in this TS measure a parameter relative to a value that is not fully specified in the UTRA specifications. For these tests, the Minimum Requirement is determined relative to a nominal value specified by the manufacturer.
Certain functions of a BS are optional in the UTRA specifications. Some requirements for the BS may be regional as listed in subclause 5.17.
When specified in a test, the manufacturer shall declare the nominal value of a parameter, or whether an option is supported.
5.1 Base station classes
5.1.1 Applicability of requirements and BS class definition
The requirements in this specification apply to Wide Area base stations, Local Area base stations and Home Base Stations in co-ordinated network operation, unless otherwise stated.
Wide Area BS are characterised by requirements derived from Macro Cell and Micro Cell scenarios with BS to UE coupling losses equal to 70 dB and 53 dB. The Wide Area Base Station has the same requirements as the base station for General Purpose application in Release 99 for 3,84 Mcps option, and in release 4 for both 3,84 Mcps and 1,28 Mcps option.
Local Area BS are characterised by requirements derived from Pico Cell scenarios with a BS to UE coupling loss equals to 45 dB.
Home Base Stations are characterised by requirements derived from Femto Cell scenarios.
5.1.2 Manufacturer’s declaration of supported RF configurations
The manufacturer shall declare which operational configurations the BS supports by declaring the following parameters:
– The intended class of the BS under test according to clause 5.1.1
– The supported operating bands defined in clause 4.2;
– The frequency range within the above operating band(s) supported by the BS;
– The maximum Base Station RF bandwidth supported by a BS within each operating band;
– The supported operating configurations (multi-carrier and/or single carrier) within each operating band;
– The rated output power per carrier, PRAT;
– The rated total output power as a sum of all carriers;
– Maximum number of supported carriers within each band;
– Total number of supported carriers
If the rated total output power and total number of supported carriers are not simultaneously supported, the manufacturer shall declare the following additional parameters:
– The reduced number of supported carriers at the rated total output power;
– The reduced total output power at the maximum number of supported carriers.
For BS capable of multi-band operation, the parameters above shall be declared for each supported operating band in single-band operation. In addition the manufacturer shall declare the following additional parameters for BS capable of multi-band operation:
– Supported operating band combinations of the BS
– Supported operating band(s) of each antenna connector
– Support of multi-band transmitter and/or multi-band receiver, including mapping to antenna connector(s)
– Total number of supported carriers for the declared band combinations of the BS
– Maximum number of supported carriers per band in multi-band operation
– Total RF bandwidth of transmitter and receiver for the declared band combinations of the BS
– Maximum RF bandwidth of each supported operating band in multi-band operation
– Maximum radio bandwidth in transmit and receive direction for the declared band combinations of the BS
– Any other limitations under simultaneous operation in the declared band combinations of the BS which have any impact on the test configuration generation
– Total output power as a sum over all supported operating bands in the declared band combinations of the BS
– Maximum supported power difference between any two carriers in any two different supported operating bands
– The rated output power per carrier in multi-band operation

5.2 Output power
Void
5.3 Specified frequency range and supported channel bandwidth
The manufacturer shall declare:
– which of the frequency bands defined in sub-clause 4.2 are supported by the BS.
– the frequency range within the above frequency band(s) supported by the BS. As TDD is employed, the same frequency range is used for transmit and receive operation. For the case of MBSFN-only operation, the frequency range is used for transmit only, since no receive requirement exists.
For the single carrier testing, many tests in this TS are performed with appropriate frequencies in the bottom, middle and top of the operating frequency band of the BS. These are denoted as RF channels B (bottom), M (middle) and T (top).
Unless otherwise stated, the test shall be performed with a single carrier at each of the RF channels B, M and T.
When a test is performed by a test laboratory, the UARFCNs to be used for RF channels B, M and T shall be specified by the laboratory. The laboratory may consult with operators, the manufacturer or other bodies.
When a test is performed by a manufacturer, the UARFCNs to be used for RF channels B, M and T may be specified by an operator.
5.3.1 RF bandwidth position for multi-carrier testing
Many tests in this TS are performed with the maximum RF bandwidth located at the bottom, middle and top of the supported frequency range in each operating band. These are denoted as BRFBW(bottom), MRFBW (middle) and TRFBW (top).
Unless otherwise stated, the test shall be performed at BRFBW, MRFBW and TRFBW defined as following:
– BRFBW: maximum RF bandwidth located at the bottom of the supported frequency range in each operating band;
– MRFBW: maximum RF bandwidth located in the middle of the supported frequency range in each operating band;
– TRFBW: maximum RF bandwidth located at the top of the supported frequency range in each operating band.
For BS capable of dual-band operation, unless otherwise stated, the test shall be performed at BRFBW_T’RFBW and B’RFBW_TRFBW defined as following:
BRFBW_ T’RFBW: the RF bandwidths located at the bottom of the supported frequency range in the lower operating band and at the highest possible simultaneous frequency position, within the maximum radio bandwidth, in the upper operating band.
B’RFBW_TRFBW: the RF bandwidths located at the top of the supported frequency range in the upper operating band and at the lowest possible simultaneous frequency position, within the maximum radio bandwidth, in the lower operating band.
NOTE: BRFBW_T’RFBW = B’RFBW_TRFBW = BRFBW_TRFBW when the declared maximum radio bandwidth spans both operating bands. BRFBW_TRFBW means the RF bandwidths are located at the bottom of the supported frequency range in the lower operating band and at the top of the supported frequency range in the upper operating band.
When a test is performed by a test laboratory, the position of BRFBW, MRFBW and TRFBW in each supported operating band, as well as the position of BRFBW_T’RFBW and B’RFBW_TRFBW in the supported operating band combinations, shall be specified by the laboratory.

The Test Tolerances defined in this subclause have been used to relax the Minimum Requirements in this specification to derive the Test Requirements.
The Test Tolerances are derived from Test System uncertainties, regulatory requirements and criticality to system performance. As a result, the Test Tolerance may sometimes be set to zero.
The test tolerances should not be modified for any reason, e. g. to take account of commonly known test system errors (such as mismatch, cable loss, etc.)

The measurement results returned by the Test System are compared – without any modification – against the Test Requirements as defined by the shared risk principle.
The Shared Risk principle is defined in ITU-R M.1545 [13].
The actual measurement uncertainty of the Test System for the measurement of each parameter shall be included in the test report.
The recorded value for theTest System uncertainty shall be, for each measurement, equal to or lower than the appropriate figure in subclause 5.10 of this TS.
If the Test System for a test is known to have a measurement uncertainty greater than that specified in subclause 5.10, it is still permitted to use this equipment provided that an adjustment is made as follows:
Any additional uncertainty in the Test System over and above that specified in subclause 5.10 shall be used to tighten the Test Requirement – making the test harder to pass. (For some tests, e. g. receiver tests, this may require modification of stimulus signals).
This procedure (defined in Annex D) will ensure that a Test System not compliant with subclause 5.10 does not increase the chance of passing a device under test where that device would otherwise have failed the test if a Test System compliant with subclause 5.10 had been used.
5.13 Selection of configurations for testing
Measurements shall be performed within the time slots under test as specified individually for each test within the subclause "Initial conditions".
Most tests in this TS are only performed for a subset of the possible combinations of test conditions. For instance:
‑ Not all TRXs in the configuration may be specified to be tested.
‑ Only one RF channel may be specified to be tested.
‑ Only one timeslot may be specified to be tested.
When a test is performed by a test laboratory, the choice of which combinations are to be tested shall be specified by the laboratory. The laboratory may consult with operators, the manufacturer or other bodies.
When a test is performed by a manufacturer, the choice of which combinations are to be tested may be specified by an operator.
5.14 BS Configurations
This TS has been written to specify tests for the standard configurations of BS which have been assumed in UTRA requirements specifications, in particular TS 25.105 [1]. However, there are other configurations of BS which comply with these specifications, but for which the application of these specifications is not fully defined. For some such configurations there may be alternate ways to apply the requirements of this specification to testing of the configuration, or some variation in the test method may be necessary. It may therefore be necessary for the parties to the testing to reach agreement over the method of testing in advance.
If the BS is supplied in a number of different environmental enclosures or configurations, it may not be necessary to test RF parameters for each environmental configuration, provided that it can be demonstrated that the equipment has been tested at the worst internal environmental conditions.
Where alternative interpretations of this specification are possible for a BS configuration under test, the interpretation which has been adopted in performing the test shall be recorded with the test results.
Where variation in the test method within this TS has been necessary to enable a BS configuration to be tested, the variation in the test method which has been made in performing the test shall be recorded with the test results. Where possible, agreement should be reached in advance about the nature of such a variation with any party who will later receive the test results.
Possible interpretations of this TS for some common configurations are given in the following subclauses.
5.14.1 Receiver diversity
For the tests in clause 7 of the present document, the requirement applies at each receiver antenna connector for receivers with antenna diversity.
Receiver requirements are tested at the antenna connector, with the remaining receiver(s) disabled or their antenna connector(s) being terminated. If the manufacturer has declared the receiver paths to be equivalent, it is sufficient to apply the specified test signal at any one of the receiver antenna connectors.
For a multi-band BS, multi-band tests for blocking and intermodulation are performed with the interferer(s) applied to each antenna connector mapped to the receiver for the wanted signal(s), however only to one antenna at a time. Antenna connectors to which no signals are applied are terminated.
5.14.2 Duplexers
Due to TDD operation, there is no need to use a duplexer in the BS.
5.14.3 Power supply options
If the BS is supplied with a number of different power supply configurations, it may not be necessary to test RF parameters for each of the power supply options, provided that it can be demonstrated that the range of conditions over which the equipment is tested is at least as great as the range of conditions due to any of the power supply configurations.
This applies particularly if a BS contains a DC rail which can be supplied either externally or from an internal mains power supply. In this case, the conditions of extreme power supply for the mains power supply options can be tested by testing only the external DC supply option. The range of DC input voltages for the test should be sufficient to verify the performance with any of the power supplies, over its range of operating conditions within the BS, including variation of mains input voltage, temperature and output current.
5.14.4 Ancillary RF amplifiers
The requirements of this TS shall be met with the ancillary RF amplifier fitted. At tests according to clause 6 and 7 for TX and RX respectively, the ancillary amplifier is connected to the BS by a connecting network (including any cable(s), attenuator(s), etc.) with applicable loss to make sure the appropriate operating conditions of the ancillary amplifier and the BS. The applicable connecting network loss range is declared by the manufacturer. Other characteristics and the temperature dependence of the attenuation of the connecting network are neglected. The actual attenuation value of the connecting network is chosen for each test as one of the applicable extreme values. The lowest value is used unless otherwise stated.
Sufficient tests should be repeated with the ancillary amplifier fitted and, if it is optional, without the ancillary RF amplifier to verify that the BS meets the requirements of this TS in both cases.
5.14.5 BS using antenna arrays
A BS may be configured with a multiple antenna port connection for some or all of its TRXs or with an antenna array related to one cell (not one array per TRX). This subclause applies to a BS which meets at least one of the following conditions:
– The transmitter output signals from one or more TRX appear at more than one antenna port, or
– there is more than one receiver antenna port for a TRX or per cell and an input signal is required at more than one port for the correct operation of the receiver (NOTE: diversity reception does not meet this requirement) thus the outputs from the transmitters as well as the inputs to the receivers are directly connected to several antennas (known as "aircombining"), or
If a BS is used, in normal operation, in conjunction with an antenna system which contains filters or active elements which are necessary to meet the UTRA requirements, the tests of conformance may be performed on a system comprising the BS together with these elements, supplied separately for the purposes of testing. In this case, it must be demonstrated that the performance of the configuration under test is representative of the system in normal operation, and the conformance assessment is only applicable when the BS is used with the antenna system.
For testing of conformance of such a BS, the following procedure may be used:
5.14.5.1 Receiver tests
For each test, the test signals applied to the receiver antenna connectors shall be such that the sum of the powers of the signals applied equals the power of the test signal(s) specified in the test.
An example of a suitable test set up is shown in figure 5.1.
Figure 5.1: Receiver test set up
For spurious emissions from the receiver antenna connector, the test may be performed separately for each receiver antenna connector.
5.14.5.2 Transmitter tests
For each test, the conformance requirement shall be met by the sum of the signals emitted by each transmitter antenna connector. This may be assessed by separately measuring the signals emitted by each antenna connector and summing the results, or by combining the signals and performing a single measurement. The characteristics (e.g. amplitude and phase) of the combining network should be such that the power of the combined signal is maximised.
An example of a suitable test set up is shown in figure 5.2.
Figure 5.2: Transmitter test set up
For Intermodulation attenuation, the test may be performed separately for each transmitter antenna connector.
5.14.6 MIMO transmission
Unless otherwise stated, for the tests in clause 6 of the present document, the requirement applies for each transmitter antenna connector in the case of MIMO transmission.
Transmitter requirements are tested at the antenna connector, with the remaining antenna connector(s) being terminated. If the manufacturer has declared the transmitter paths to be equivalent, it is sufficient to measure the signal at any one of the transmitter antenna connectors.
5.15 Overview of the conformance test requirements
Tables 5.9, 5.10 and 5.11 give an overview of the conformance test requirements for the transmitter, the receiver and system performance, respectively. Requirements related to receive functionality for the BS under test do not apply for the case of MBSFN-only operation.

5.20 Test configurations for multi-carrier operation
The test configurations shall be constructed using the methods defined below, subject to the parameters declared by the manufacturer for the supported RF configurations as listed in subclause 5.1.2. The applicable test configurations to be use for conformance testing are defined for each supported RF configuration in clause 5.21.
Note: The test configurations in this subclause are intended for UTRA TDD 1.28Mcps option.
5.20.1 UTTC1: Multi-carrier operation test configuration
The purpose of the UTTC1 is to test both BS transmitter and receiver requirements.
5.20.1.1 UTTC1 generation
UTTC1 should be constructed using the following method:
– The RF bandwidth shall be the declared maximum supported RF bandwidth.
– Place two UTRA TDD 1.28Mcps option carriers adjacent to the high and low edge of the RF bandwidth.
– For transmitter tests, alternately place a UTRA TDD 1.28Mcps option carrier adjacent to the already placed carriers at the low and high edge of the RF bandwidth until there is no more space to fit a carrier or the BS does not support more carriers. The nominal carrier spacing defined in clause 4.4.1 shall apply.
5.20.1.1 UTTC1 power allocation
Set the power of each carrier to the same level so that the sum of the carrier powers equals the rated total output power according to the manufacturer’s declaration in sub clause 5.1.2.
5.20.2 UTTC2: Multi-band test configuration for full carrier allocation
The purpose of the UTTC2 is to test multi-band operation aspects considering maximum supported number of carriers.
5.20.2.1 UTTC2 generation
UTTC2 is based on re-using the exsiting test configuration applicable per band involved in multi-band operation. It is constructed using the following method:
● The RF bandwidth of each supported operating band in multi-band operation shall be the declared maximum RF bandwidth of each supported operating band in multi-band operation.
● The number of carriers of each supported operating band shall be the declared maximum number of supported carrier of each supported operating band in multi-band operation. Carriers shall first be placed at the outermost edges of the declared maximum radio bandwidth. Additional carriers shall next be placed at the edges of the RF bandwidths, if possible.
● The allocated RF bandwidth of the outermost bands shall be located at the outermost edges of the declared maximum radio bandwidth.
● Each concerned band shall be considered as an independent band and the corresponding UTTC1shall be generated in each band. The mirror image of the single-band test configuration shall be used in the highest band being tested for the BS to ensure a narrowband carrier being placed at both edges of the BS maximum radio bandwidth.
● If a multi-band BS supports only 3 carriers, two carriers shall be placed in one band according to UTTC1while the remaining carrier shall be placed at the edge of the maximum radio bandwidth in the other band.
● If the sum of the maximum RF bandwidth of each supported operating bands is larger than the declared total RF bandwidth of transmitter and receiver for the declared band combinations of the BS, repeat the steps above for test configurations where the RF bandwidth of one of the operating band shall be reduced so that the total RF bandwidth of transmitter and receiver is not exceeded and vice versa.
● If the sum of the maximum number of supported carrier of each supported operating bands in multi-band operation is larger than the declared total number of supported carriers for the declared band combinations of the BS, repeat the steps above for test configurations where in each test configuration the number of carriers of one of the operating band shall be reduced so that the total number of supported carriers is not be exceeded and vice versa.
5.20.2.2 UTTC2 power allocation
Unless otherwise stated, set the power of each carrier in all supported operating bands to the same power so that the sum of the carrier powers equals the total output power according to the manufacturer’s declaration.
If the allocated power of a supported operating band(s) exceeds the declared rated total output power of the operating band(s) in multi-band operation, the exceeded part shall, if possible, be reallocated into the other band(s). If the power allocated for a carrier exceeds the rated output power declared for that carrier, the exceeded power shall, if possible, be reallocated into the other carriers.
5.21 Applicability of test configurations
The present clause defines for each RF test requirement the set of mandatory test configurations which shall be used for demonstrating conformance. The applicable test configurations are specified in the tables below for each supported RF configuration, which shall be declared according to subclause 5.1.2. The generation and power allocation for each test configuration is defined in clause 5.20.
For a BS declared to be capable of single carrier operation only, a single carrier (SC) shall be used for testing.
For a BS declared to be capable of multi-carrier operation in contiguous spectrum operation only, the test configurations in Table 5.14 shall be used for testing.
Note: The applicability of test configurations in this subclause is only applicable to UTRA TDD 1.28Mcps option.

5.22 Requirements for BS capable of multi-band operation
For BS capable of multi-band operation, the RF requirements in clause 6 and 7 apply for each supported operating band unless otherwise stated. For some requirements it is explicitly stated that specific additions or exclusions to the requirement apply for BS capable of multi-band operation. In the case where multiple bands are mapped on separate antenna connectors, the following applies:
– Single-band transmitter spurious emissions, operating band unwanted emissions, ACLR, transmitter intermodulation and receiver spurious emissions requirements apply to each antenna connector.
– If the BS is configured for single-band operation, single-band requirements shall apply to the antenna connector configured for single-band operation and no exclusions or provisions for multi-band capable BS are applicable. Single-band requirements are tested separately at the antenna connector configured for single-band operation, with all other antenna connectors terminated.
For a BS capable of multi-band operation, the RF requirements in the present specification assume synchronized operation, where no simultaneous uplink and downlink occur between the supported operating bands.
