4.1 Measurement uncertainties and test requirements

4.1.1 General

The requirements of this clause apply to all applicable tests in part 1 of this specification, i.e. to all conducted test

The minimum requirements are given in TS 37.105 [6] and the references therein. Test requirements are given in this specification or are included by reference to TS 25.141 [15], TS 25.142 [19], TS 36.141 [14], TS 38.141-1 [37] or TS 37.141 [13]. Test Tolerances for the conducted test requirements explicitly stated in the present document are given in annex C of the present document. Test Tolerances for test requirements included by reference to TS 25.141 [15], TS 25.142 [19], TS 36.141 [14], TS 38.141-1 [37] or TS 37.141 [13] are defined in the respective referred test specification.

Test requirements and Test Tolerances for NB-IoT in-band, NB-IoT guard band, or standalone NB-IoT operation are not supported by AAS BS and not covered by this specification. When referring to standalone E-UTRA test requirements for single RAT operation in TS 36.141 [14] or to E-UTRA test requirements for MSR operation in TS 37.141 [13], any test requirements specified in those specifications for E-UTRA with NB-IoT (in-band or guard band) or for standalone NB-IoT, shall not be considered for the AAS BS. Unless otherwise stated, the exclusion of the NB-IoT test requirements in this specification applies to all operation modes (i.e. in-band NB-IoT operation, guard band NB-IoT operation and standalone NB-IoT operation).

Test Tolerances are individually calculated for each test. The Test Tolerances are used to relax the minimum requirements to create test requirements.

When a test requirement differs from the corresponding minimum requirement, then the Test Tolerance applied for the test is non-zero. The Test Tolerance for the test and the explanation of how the minimum requirement has been relaxed by the Test Tolerance are given in annex C.

4.1.2 Acceptable uncertainty of Test System

4.1.2.1 General

The maximum acceptable uncertainty of the Test System is specified below for each test defined explicitly in the present specification, where appropriate. The maximum acceptable uncertainty of the Test System for test requirements included by reference is defined in the respective referred test specification.

When a requirement is applied per TAB connector then the test uncertainty is applied to the measured value. When a requirement is applied for a group of TAB connectors then the test uncertainty is applied to sum of the measured power on each TAB connector in the group.

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 4.1.2 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.

NOTE: Unless otherwise noted, only the Test System stimulus error is considered here. The effect of errors in the throughput measurements or the BER/FER due to finite test duration is not considered.

4.1.3 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 Recommendation ITU-R M.1545 [7].

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 4.1.2 of the present document.

If the Test System for a test is known to have a measurement uncertainty greater than that specified in clause 4.1.2, 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 4.1.2 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 will ensure that a Test System not compliant with clause 4.1.2 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 clause 4.1.2 had been used.

4.2 Conducted and radiated requirement reference points

AAS BS requirements are defined for two points of reference, signified by radiated requirements and conducted requirements.

Figure 4.2-1: Radiated and conducted points of reference of AAS BS

Radiated characteristics are defined over the air (OTA) with a point of reference in the far field (Fraunhofer) region. Radiated requirements are also referred to as OTA requirements.

Conducted characteristics are defined at individual or groups of TAB connectors at the transceiver array boundary, which is the conducted interface between the transceiver unit array and the composite antenna.

The transceiver unit array is part of the composite transceiver functionality generating modulated transmit signal structures and performing receiver combining and demodulation.

The transceiver unit array contains an implementation specific number of transmitter units and an implementation specific number of receiver units. Transmitter units and receiver units may be combined into transceiver units. The transmitter/receiver units have the ability to receive/send parallel independent modulated symbol streams.

The composite antenna contains a radio distribution network (RDN) and an antenna array. The RDN is a linear passive network that distributes the RF power between the transceiver array boundary and the antenna array, in an implementation specific way.

How a conducted requirement is applied to the transceiver array boundary is detailed in the respective requirement clause.

Part 1 of this specification details the test requirements of the conducted requirements only and hence only requires the conducted reference points.

4.3 Base station classes for AAS BS

The requirements in this specification apply to AAS BS of Wide Area BS, Medium Range BS and Local Area BS classes unless otherwise stated.

Wide Area BS are characterised by requirements derived from Macro Cell scenarios. For a hybrid AAS BS of Wide Area BS class, the minimum coupling loss between any TAB connector and the UE is 70 dB.

NOTE: Whenever WA BS is referred in this specification, the NB-IoT Wide Area BS and related requiremetns as defined in TS 36.104 [4], are not applicable for AAS BS.

Medium Range BS are characterised by requirements derived from Micro Cell scenarios. For a hybrid AAS BS of Medium Range BS class, the minimum coupling loss between any TAB connector and the UE is 53 dB.

Local Area BS are characterised by requirements derived from Pico Cell scenarios. For a hybrid AAS BS of Local Area BS class, the minimum coupling loss between any TAB connector and the UE is 45 dB.

4.4 Regional requirements

Some requirements in the present document may only apply in certain regions either as optional requirements, or set by local and regional regulation as mandatory requirements. It is normally not stated in the 3GPP specifications under what exact circumstances that the requirements apply, since this is defined by local or regional regulation.

Table 4.4-1 lists all requirements in the present specification that may be applied differently in different regions. Non-AAS requirements are applicable as defined in the present document. In many cases, such requirements include regional requirements that are implicitly referenced from the present specification, and listed in the specification for the specifications concerned [2] [5].

Table 4.4-1: List of regional requirements

Clause number	Requirement	Comments
4.5	Operating bands and Band Categories	Some bands may be applied regionally.
6.6.2	Occupied bandwidth	The requirement may be applied regionally. There may also be regional requirements to declare the Occupied bandwidth according to the definition.
6.6.4	Spectrum emission mask	The mask specified may be mandatory in certain regions. In other regions this mask may not be applied. Additional spectrum protection requirements may apply regionally.
6.6.5	Operating band unwanted emissions	The BS may have to comply with the applicable emission limits established by FCC Title 47 [15], when deployed in regions where those limits are applied and under the conditions declared by the manufacturer.

6.6.5	Operating band unwanted emissions	Additional Band 32 unwanted emissions requirements may apply in certain regions.
6.6.6	Spurious emissions	Category A limits are mandatory for regions where Category A limits for spurious emissions, as defined in Recommendation ITU-R SM.329 [35] apply. Category B limits are mandatory for regions where Category B limits for spurious emissions, as defined in Recommendation ITU-R SM.329 [35] apply.
6.6.6	Spurious emissions	Additional spurious emissions requirements may be applied for the protection of system operating in frequency ranges other than the AAS BS operating band as described in TS 37.104 [12] clause 6.6.1.3.
6.6.6	Spurious emissions	In addition to 3GPP requirements, the BS may have to comply with the applicable emission limits established by FCC Title 47 [15], when deployed in regions where those limits are applied, and under the conditions declared by the manufacturer.
6.6.6	Spurious emissions	The emission limits specified as the basic limit + X (dB) are applicable, unless stated differently in regional regulation.
6.7	Transmitter intermodulation	Additional requirements may apply in certain regions.
7.6	Rx spurious emissions	The emission limits specified as the basic limit + X (dB) are applicable, unless stated differently in regional regulation.

4.5 Operating bands and band categories

The operating bands and band categories for AAS BS are the same as for non-AAS BS, as described in TS 37.104 [5]. In addition, band category aspects described in TS 37.141, clauses 4.4.1, 4.4.2 and 4.4.3, shall apply.

NOTE 1: AAS BS does not support GSM, but BC2 is still applicable for protection of/against GSM operation in BC2 operating bands.

NOTE 2: AAS BS does not support Band 46 (and all its sub-bands defined in TS 36.104 [12], clause 5.5) operation, but Band 46 test requirements are still applicable for AAS BS for protection of and against Band 46 operation.

NOTE 3: Bands in BC1 and BC2 categories are also used for NB-IoT operation. NB-IoT is not applicable for AAS BS.

4.6 Channel arrangements

The channel arrangements for AAS BS are the same as those for UTRA non-AAS BS and/or E-UTRA non-AAS BS and/or NR non-AAS BS as described in TS 37.104 [5].

NOTE: Test requirements for nominal carrier spacing of 19.8 MHz and 20.1 MHz for carriers in Band 46 as specified in 36.104 [12] clause 5.7.1, are not applicable for AAS BS.

4.7 Requirements for AAS BS capable of multi-band operation

For AAS BS capable of operation in multiple operating bands, the RF requirements in clause 6 and 7 apply separately to each supported operating band unless otherwise stated.

An AAS BS may be capable of supporting operation in multiple operating bands with one of the following implementations of TAB connectors in the transceiver array boundary:

– All TAB connectors are single band TAB connectors:

– Different sets of single band TAB connectors support different operating bands, but each TAB connector supports only operation in one single operating band.

– Sets of single band TAB connectors support operation in multiple operating bands with some single band TAB connectors supporting more than one operating band.

– All TAB connectors are multiband TAB connectors.

– A combination of single band sets and multi-band sets of TAB connectors provides support of the AAS BS capability of operation in multiple operating bands.

Unless otherwise stated all requirements specified for an operating band apply only to the set of TAB connectors supporting that operating band.

In certain requirements it is explicitly stated that specific additions or exclusions to the requirement apply at multi-band TAB connectors as detailed in the requirement clause.

In the case of an operating band being supported only by single band TAB connectors in a TAB connector TX min cell group or a TAB connector RX min cell group, single band requirements apply to that set of TAB connectors.

NOTE: Each supported operating band needs to be operated separately during conformance testing on single band TAB connectors.

In the case of an operating band being supported only by multi-band TAB connectors supporting the same operating band combination in a TAB connector TX min cell group or a TAB connector RX min cell group, multi-band requirements apply to that set of TAB connectors.

The case of an operating band being supported by both multi-band TAB connectors and single band TAB connectors in a TAB connector TX min cell group or a TAB connector RX min cell group is not covered by the present release of this specification.

The case of an operating band being supported by multi-band TAB connectors which are not all supporting the same operating band combination in a TAB connector TX min cell group or a TAB connector RX min cell group is not covered by the present release of this specification.

For multi-band TAB connectors supporting the bands for TDD, the RF requirements in the present specification assume no simultaneous uplink and downlink occur between the bands.

The RF requirements for multi-band TAB connectors supporting bands for both FDD and TDD are not covered by the present release of this specification.

4.8 AAS BS configurations

4.8.1 Transmit configurations

Unless otherwise stated, the conducted transmitter characteristics in clause 6 are specified at the AAS BS transceiver array boundary at the TAB connector(s) antenna connector with a full complement of transceiver units for the configuration in normal operating conditions.

Figure 4.8.1-1: Transmitter test ports

Unless otherwise stated, for the tests in clause 6 of the present document, the requirement applies for each transmit TAB connector.

4.8.2 Receive configurations

Unless otherwise stated, the conducted receiver characteristics in clause 7 are specified at the TAB connector with a full complement of transceiver units for the configuration in normal operating conditions.

Conducted receive requirements are tested at the TAB connector, with the remaining receiver units(s) disabled or their TAB connector(s) being terminated.

4.8.3 Power supply options

If the AAS 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.

4.8.4 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 6.6.4 and 7.6 shall be measured only for frequencies above 20 MHz with the integrated Iuant BS modem switched on.

4.9 Capability sets

Capability set is defined as the TAB connectors capability to support certain RAT combinations in an operating band.

The manufacturer shall declare (D6.12) the supported capability set(s) according to table 4.9-1 for each supported TAB connector(s) and supported operating band(s).

The applicable test configurations for each RF requirement are defined in clauses 5.1, 5.2 and 5.3 for the declared capability set(s). For a multi-band TAB connector the applicable test configurations for each RF requirement are defined in clause 5.4 for the declared capability set(s).

NOTE: Not every supported configuration within a capability set is tested, but the tables in clauses 5.2, 5.3 and 5.4 provide a judicious choice among the supported configurations and test configurations to ensure proper test coverage.

For single carrier tests unless otherwise stated the tests shall be performed with a single carrier at each of the RF channels B, M and T.

Many tests in this TS are performed with the maximum Base Station RF Bandwidth located at the bottom, middle and top of the supported frequency range in the operating band. These are denoted as B_RFBW (bottom), M_RFBW (middle) and T_RFBW (top).

Unless otherwise stated, the test shall be performed at B_RFBW, M_RFBW and T_RFBW defined as following:

– B_RFBW: maximum Base Station RF Bandwidth located at the bottom of the supported frequency range in the operating band.

– M_RFBW: maximum Base Station RF Bandwidth located in the middle of the supported frequency range in the operating band. M_RFBW may be shifted maximum 100 kHz towards lower frequencies to align carriers with the channel raster.

– T_RFBW: maximum Base Station RF Bandwidth located at the top of the supported frequency range in the operating band.

For the test of certain conducted RF requirements the present specification refers to test procedures defined in the single-RAT specifications [15], [14], [19]. In this case, the interpretation of the RF channels to be tested shall be according to the definitions in the corresponding single-RAT specifications [15], [14], [19].

Occupied bandwidth test in this TS is performed with the Aggregated Channel Bandwidth and sub-block bandwidths located at the bottom, middle and top of the supported frequency range in the operating band. These are denoted as B_{BW Channel CA}(bottom), M_{BW Channel CA} (middle) and T_{BW Channel CA} (top) for contiguous spectrum operation.

Unless otherwise stated, the test for contiguous spectrum operation shall be performed at B_{BW Channel CA}, M_{BW Channel CA}and T_{BW Channel CA}defined as following:

– B_{BW Channel CA}: Aggregated Channel Bandwidth located at the bottom of the supported frequency range in each operating band;

– M_{BW Channel CA}: Aggregated Channel Bandwidth located close in the middle of the supported frequency range in each operating band, with the center frequency of each component carrier aligned to the channel raster;

– T_{BW Channel CA}: Aggregated Channel Bandwidth located at the top of the supported frequency range in each operating band.

For a multi-band TAB connector capable of dual-band operation, unless otherwise stated, the test shall be performed at B_RFBW_T’_RFBW and B’_RFBW_T_RFBW defined as following:

– B_RFBW_ T’_RFBW: the Base Station 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_T_RFBW: the Base Station 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: B_RFBW_T’_RFBW = B’_RFBW_T_RFBW = B_RFBW_T_RFBW when the declared maximum Radio Bandwidth (see table 4.10-1, D6.16) spans both operating bands.
