4.1 Measurement uncertainties and test requirements

4.1.1 General

The requirements of this clause apply to all applicable tests in part 2 of this specification, i.e. to all AAS BS radiated tests.

The minimum requirements for AAS BS radiated requirements are given in TS 37.105 [14] clause 9 and 10 for the radiated transmitter and radiated receiver characteristics, respectively. Test Tolerances for the radiated test requirements explicitly stated in part 2 of the present specification are given in annex C of this specification.

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 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 details on measurement uncertainty budget calculation, OTA measurement methodology description (including calibration and measurement stage for each test range), MU budget format and its contributions, refer to TR 37.941 [38].

NOTE 2: Fulfilling the criteria for CLTA selection and placement in clause 4.15 is deemed sufficient for the test purposes. When these criteria are met, the measurement uncertainty related to the selection of the co-location test antenna and its alignment as specified in the appropriate measurement uncertainty budget in TR 37.941 [38], shall be used for evaluating the test system uncertainty.

4.1.2.4 Measurement of performance requirement

The measurement uncertainties for the performance requirements are the same as those quoted in TS 36.141 [12] clause 4.2.1.3 and TS 25.141 [10] clause 4.1.4.

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 [8].

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 (defined in annex C) 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 (RIB) and conducted requirements (TAB).

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

Figure 4.3-2: Radiated points of reference of OTA AAS BS

Radiated characteristics are defined over the air (OTA) at the radiated interface boundary (RIB). Radiated requirements are also referred to as OTA requirements. The (spatial) directions in which the OTA requirements apply are detailed for each requirement.

Some OTA requirements are specified as co-location requirements where the requirements are specified at the conducted interface of the co-location reference antenna, co-location requirements are further defined in clause 4.15

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.

The present document details the test requirements of the radiated requirements only and hence only requires the radiated 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.

The base station classes are defined in TS 37.105 [6].

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].

7.7	OTA Rx spurious emissions	The emission limits specified as the basic limit + X (dB) are applicable, unless stated differently in regional regulation.
NOTE: AAS BS does not support Band 46 operation, but additional spurious emissions requirements for Band 46 as described in TS 37.104 [5] clause 6.6.1.3, are still applicable for AAS BS for protection of Band 46 operation.

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 [6]. 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 [4]) operation. Conducted Band 46 test requirements are still applicable for AAS BS for protection of and against Band 46 operation, as specified in TS 37.145-1 [9].

4.6 Channel arrangements

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

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.

A hybrid 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 hybrid 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 subclause. When referencing the NR specification 3GPP TS 38.104 [33] for a BS type 1-H the multi-band connector term is equivalent to a multi-band TAB connector in this specification.

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.

For a band supported by a TAB connector where the transmitted carriers are not processed in active RF components together with carriers in any other band, TX single band requirements shall apply. For a band supported by a TAB connector where the received carriers are not processed in active RF components together with carriers in any other band, RX single band requirements shall apply.

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.

An OTA AAS BS may be capable of supporting operation in multiple operating bands with one of the following implementations at the radiated interface boundary:

– All RIBs are single band RIBs.

– All RIBs are multiband RIBs.

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

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

NOTE: Each supported operating band needs to be operated separately during conformance testing for single RIBs.

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

A RIB may operate multi-RAT where the individual RATs are operated in different RAT specific bands that partially or fully overlap; Δf_OBUE and Δf_OOB are according to the combined frequency range occupied by the overlapping bands.

4.8 AAS BS configurations

4.8.1 Transmit configurations

Unless otherwise stated, the radiated transmitter characteristics in clause 6 are specified at the radiated interface boundary (RIB). The AAS BS shall have a full complement of transceiver units for the configuration in normal operating conditions.

Figure 4.8.1-2: Transmitter test interfaces for co-location concept

4.8.2 Receive configurations

Unless otherwise stated, the radiated receiver characteristics in clause 7 are specified at the radiated interface boundary (RIB). The AAS BS shall have a full complement of transceiver units for the configuration in normal operating conditions.

Figure 4.8.2-2: Receiver test interfaces for co-location concept

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.

4.9 Capability sets

A radiated capability set is defined as the AAS BS capability to support certain RAT combinations in an operating band.

The manufacturer shall declare (D9.25) the supported radiated capability set(s) according to table 4.9-1 for each supported operating band.

The applicable test configurations for each RF requirement are defined in clause 5.1, 5.2 and 5.3 for the declared radiated capability set(s). For beams with multi-band beam dependencies the applicable test configurations for each RF requirement are defined in clause 5.4 for the declared radiated 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.

4.10 Manufacturer declarations

The AAS BS declarations categories D9.x and D10.x listed in table 4.10-1 are required to be provided by the manufacturer for the radiated requirements testing of the hybrid AAS BS or the OTA AAS BS.

For the hybrid AAS BS declarations required for the conducted requirements testing, refer to TS 37.145-1 [9], clause 4.10.

NOTE 1: D9.x declarations are related to the radiated Tx requirements, while D10.x declarations are related to the radiated Rx requirements.

NOTE 2: From Rel-15 onwards, additional D11.x declarations are introduced in table 4.10-2 for OTA AAS BS, in order to easily distinguish from the Rel-13/14 OTA declarations which are also applicable for hybrid AAS BS. Declarations in table 4.10-2 are applicable to OTA AAS BS only.
