4 General test conditions and declarations
25.1413GPPBase Station (BS) conformance testing (FDD)Release 17TS
Many of the tests in this specification 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 clause 4.7.
When specified in a test, the manufacturer shall declare the nominal value of a parameter, or whether an option is supported. The manufacturer declarations are listed in clauses 4.8 and 4.11.
4.1 Acceptable uncertainty of Test System
The maximum acceptable uncertainty of the Test System is specified below for each test, where appropriate. The Test System shall enable the stimulus signals in the test case to be adjusted to within the specified tolerance and 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.
For RF tests, it should be noted that the uncertainties in clause 4.1 apply to the Test System operating into a nominal 50 ohm load and do not include system effects due to mismatch between the DUT and the Test System.
4.1.1 Measurement of test environments
The measurement accuracy of the BS test environments defined in Clause 4.4, Test environments shall be.
Pressure: 5 kPa.
Temperature: 2 degrees.
Relative Humidity: 5 %.
DC Voltage: 1,0 %.
AC Voltage: 1,5 %.
Vibration: 10 %.
Vibration frequency: 0,1 Hz.
The above values shall apply unless the test environment is otherwise controlled and the specification for the control of the test environment specifies the uncertainty for the parameter.

4.2 Test Tolerances (informative)
The Test Tolerances defined in this clause 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 Tolerances 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.)

4.2.4 RRM measurements
The following tolerances refer to the requirements of 25.133.
tbd
4.3 Interpretation of measurement results
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 [17].
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 the Test System uncertainty shall be, for each measurement, equal to or lower than the appropriate figure in clause 4.1 of this specification.
If the Test System for a test is known to have a measurement uncertainty greater than that specified in clause 4.1, it is still permitted to use this apparatus provided that an adjustment is made as follows.
Any additional uncertainty in the Test System over and above that specified in clause 4.1 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 F) will ensure that a Test System not compliant with clause 4.1does 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 clause 4.1 had been used.
4.3A Base station classes
The requirements in the present document apply to Wide Area Base Stations, Medium Range Base Stations, Local Area Base Stations and Home Base Stations unless otherwise stated.
Wide Area Base Stations are characterised by requirements derived from Macro Cell scenarios with a BS to UE minimum coupling loss equal to 70 dB. The Wide Area Base Station class has the same requirements as the base station for General Purpose application in Release 99, 4 and 5.
Medium Range Base Stations are characterised by requirements derived from Micro Cell scenarios with a BS to UE minimum coupling loss equal to 53 dB.
Local Area Base Stations are characterised by requirements derived from Pico Cell scenarios with a BS to UE minimum coupling loss equal to 45 dB.
Home Base Stations are characterised by requirements derived from Femto Cell scenarios.
The manufacturer shall declare the intended class of the BS under test.
4.4 Test environments
For each test in the present document, the environmental conditions under which the BS is to be tested are defined.
4.4.1 Normal test environment
When a normal test environment is specified for a test, the test should be performed within the minimum and maximum limits of the conditions stated in table 4.2.

The ranges of barometric pressure, temperature and humidity represent the maximum variation expected in the uncontrolled environment of a test laboratory. If it is not possible to maintain these parameters within the specified limits, the actual values shall be recorded in the test report.
NOTE: This may, for instance, be the case for measurements of radiated emissions performed on an open field test site.
4.4.2 Extreme test environment
The manufacturer shall declare one of the following:
1) the equipment class for the equipment under test, as defined in the IEC 60 721-3-3 [6];
2) the equipment class for the equipment under test, as defined in the IEC 60 721-3-4 [7];
3) the equipment that does not comply to the mentioned classes, the relevant classes from IEC 60 721 documentation for Temperature, Humidity and Vibration shall be declared.
NOTE: Reduced functionality for conditions that fall outside of the standard operational conditions is not tested in the present document. These may be stated and tested separately.
4.4.2.1 Extreme temperature
When an extreme temperature test environment is specified for a test, the test shall be performed at the standard minimum and maximum operating temperatures defined by the manufacturer’s declaration for the equipment under test.
Minimum temperature:
The test shall be performed with the environment test equipment and methods including the required environmental phenomena into the equipment, conforming to the test procedure of IEC 60 068-2-1 [8].
Maximum temperature:
The test shall be performed with the environmental test equipment and methods including the required environmental phenomena into the equipment, conforming to the test procedure of IEC 60 068-2-2 [9].
NOTE: It is recommended that the equipment is made fully operational prior to the equipment being taken to its lower operating temperature.
4.4.3 Vibration
When vibration conditions are specified for a test, the test shall be performed while the equipment is subjected to a vibration sequence as defined by the manufacturer’s declaration for the equipment under test. This shall use the environmental test equipment and methods of inducing the required environmental phenomena in to the equipment, conforming to the test procedure of IEC 60 068-2-6 [10]. Other environmental conditions shall be within the ranges specified in clause 4.4.1.
NOTE: The higher levels of vibration may induce undue physical stress in to equipment after a prolonged series of tests. The testing body should only vibrate the equipment during the RF measurement process.
4.4.4 Power supply
When extreme power supply conditions are specified for a test, the test shall be performed at the standard upper and lower limits of operating voltage defined by manufacturer’s declaration for the equipment under test.
Upper voltage limit:
The equipment shall be supplied with a voltage equal to the upper limit declared by the manufacturer (as measured at the input terminals to the equipment). The tests shall be carried out at the steady state minimum and maximum temperature limits declared by the manufacturer for the equipment, to the methods described in IEC 60 068-2-1 [8] Test Ab/Ad and IEC 60 068-2-2 [9] Test Bb/Bd: Dry Heat.
Lower voltage limit:
The equipment shall be supplied with a voltage equal to the lower limit declared by the manufacturer (as measured at the input terminals to the equipment). The tests shall be carried out at the steady state minimum and maximum temperature limits declared by the manufacturer for the equipment, to the methods described in IEC 60 068-2-1 [8] Test Ab/Ad and IEC 60 068-2-2 [9] Test Bb/Bd: Dry Heat.
4.4.5 Definition of Additive White Gaussian Noise (AWGN) Interferer
The minimum bandwidth of the AWGN interferer shall be 1.5 times chip rate of the radio access mode. (e.g. 5.76 MHz for a chip rate of 3.84 Mcps). The flatness across this minimum bandwidth shall be less than 0.5 dB and the peak to average ratio at a probability of 0.001% shall exceed 10 dB.
4.5 Selection of configurations for testing
Most tests in the present document are only performed for a subset of the possible combinations of test conditions. For instance:
‑ not all transceivers 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.
4.6 BS Configurations
4.6.1 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 ACS, 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.
4.6.2 Duplexers
The requirements of the present document shall be met with a duplexer fitted, if a duplexer is supplied as part of the BS. If the duplexer is supplied as an option by the manufacturer, sufficient tests should be repeated with and without the duplexer fitted to verify that the BS meets the requirements of the present document in both cases.
The following tests should be performed with the duplexer fitted, and without it fitted if this is an option:
1) clause 6.2.1, base station maximum output power, for the highest static power step only, if this is measured at the antenna connector;
2) clause 6.5, output RF spectrum emissions; outside the BS transmit band;
3) clause 6.5.3.4.3, protection of the BS receiver;
4) clause 6.6, transmit intermodulation; for the testing of conformance, the carrier frequencies should be selected to minimize intermodulation products from the transmitters falling in receive channels.
The remaining tests may be performed with or without the duplexer fitted.
NOTE 1: When performing receiver tests with a duplexer fitted, it is important to ensure that the output from the transmitters does not affect the test apparatus. This can be achieved using a combination of attenuators, isolators and filters.
NOTE 2: When duplexers are used, intermodulation products will be generated, not only in the duplexer but also in the antenna system. The intermodulation products generated in the antenna system are not controlled by 3GPP specifications, and may degrade during operation (e.g. due to moisture ingress). Therefore, to ensure continued satisfactory operation of a BS, an operator will normally select ARFCNs to minimize intermodulation products falling on receive channels. For testing of complete conformance, an operator may specify the ARFCNs to be used.
4.6.3 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.
4.6.4 Ancillary RF amplifiers
The requirements of the present document shall be met with the ancillary RF amplifier fitted. At tests according to clauses 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 the present document in both cases.
When testing, the following tests should be repeated with the optional ancillary amplifier fitted according to the table below, where x denotes that the test is applicable:

NOTE: Combining can be by duplex filters or any other network. The amplifiers can either be in RX or TX branch or in both. Either one of these amplifiers could be a passive network.
In test according to clauses 6.2 and 7.2 highest applicable attenuation value is applied.
4.6.5 BS using antenna arrays
A BS may be configured with a multiple antenna port connection for some or all of its transceivers or with an antenna array related to one cell (not one array per transceiver). This clause applies to a BS which meets at least one of the following conditions:
– the transmitter output signals from one or more transceiver appear at more than one antenna port; or
– there is more than one receiver antenna port for a transceiver or per cell and an input signal is required at more than one port for the correct operation of the receiver thus the outputs from the transmitters as well as the inputs to the receivers are directly connected to several antennas (known as "aircombining"); or
– transmitters and receivers are connected via duplexers to more than one antenna.
In case of diversity or MIMO, multiple antennas are not considered as an antenna array. 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 conformance tests 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 conformance testing of such a BS, the following procedure may be used.
4.6.5.1 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 4.1.
Figure 4.1: Receiver test set-up
For spurious emissions from the receiver antenna connector, the test may be performed separately for each receiver antenna connector.
4.6.5.2 Transmitter tests
For each test, the test signals applied to the transmitter antenna connectors (Pi) shall be such that the sum of the powers of the signals applied equals the power of the test signal(s) (Ps) specified in the test. 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 4.2.
Figure 4.2: Transmitter test set-up
For Intermodulation attenuation, the test may be performed separately for each transmitter antenna connector.
4.6.6 Transmit diversity and MIMO transmission
Unless otherwise stated, for the tests in clause 6 of the present document, the requirement applies for each transmitter antenna connector in case of transmit diversity, DB-DC-HSDPA or 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.
4.6.7 BS with integrated Iuant BS modem
Unless otherwise stated, for the tests in the present document, the integrated Iuant BS modem shall be switched off. Spurious emissions according to clauses 6.5.3 and 7.7 shall be measured only for frequencies above 20MHz with the integrated Iuant BS modem switched on.
4.6.8 BS with Virtual Antenna Mapping
A BS may be configured with virtual antenna mapping (VAM) as shown as example in Figure 4.3 for MIMO mode with two transmit antennas. The purpose of VAM is to achieve the goal of power balancing of physical channels across the multiple physical antennas when MIMO mode with two or four transmit antennas is is deployed in the downlink. Since the non-MIMO channels are transmitted only via virtual antenna 1, the transmission powers are not balanced at point a. The VAM function transforms the input signals at point a to output signals at point b such that the transmission powers are balanced.
In the following some characteristics of VAM are described in the context of MIMO mode with two transmit antennas. Similar characteristics apply also when VAM is implemented in the context of MIMO mode with four transmit antennas.
Some characteristics of VAM are as follows:
– The VAM can be represented by a unitary matrix 
– The same pair of weights (s1,s2) are applied to each physical channel that appears at virtual antenna port 1
– The same pair of weights (s3,s4) are applied to each physical channel that appears at virtual antenna port 2
– The VAM weights (s1,s2,s3,s4) should satisfy the following condition for MIMO and non-MIMO channels : 
– Power balancing at the output of VAM is achieved by setting 
– The VAM function is implemented in the digital domain prior to digital to analog conversion.
Figure 4.3: Example of VAM for MIMO mode with two transmit antennas.
If NodeB manufacturer declares the implementation of a Virtual Antenna Mapping (VAM), then the S-CPICH power accuracy test in section 6.2.3 will not be performed.

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 manufacturer’s declaration.
If the allocated power of a supported operating band(s) exceeds the declared Prated,t 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 declared Prated,c for that carrier, the exceeded power shall, if possible, be reallocated into the other carriers.
4.12.4 Applicability of test configurations
The present subclause 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 the supported RF configuration, which shall be declared according to subclause 4.11.6. The generation and power allocation for each test configuration is defined in subclauses 4.12.1 to 4.12.3.
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 in single band only, the test configurations in Table 4.6 shall be used for testing.

4.13 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.
For BS capable of multi-band operation, various structures in terms of combinations of different transmitter and receiver implementations (multi-band or single band) with mapping of transceivers to one or more antenna port(s) in different ways are possible. In the case where multiple bands are mapped on separate antenna connectors, the following applies:
– Single-band transmitter spurious emissions, spectrum emission mask, 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.
