7.8 In-channel selectivity
37.145-13GPPActive Antenna System (AAS) Base Station (BS) conformance testingPart 1: conducted conformance testingRelease 17TS
7.8.1 Definition and applicability
In-channel selectivity (ICS) is a measure of the receiver unit ability to receive a wanted signal at its assigned resource block locations in the presence of an interfering signal received at a larger power spectral density. In this condition a throughput requirement shall be met for a specified reference measurement channel. The requirement applies per TAB connector.
7.8.2 Minimum requirement
The minimum requirement for E-UTRA operation is defined in TS 37.105 [8], clause 7.8.4.
The minimum requirement for MSR operation is defined in TS 37.105 [8], clause 7.8.2.
7.8.3 Test purpose
The purpose of this test is to verify the ability of the receiver unit associated with the TAB connector under test to suppress the IQ leakage.
7.8.4 Method of test
7.8.4.1 Initial conditions
Test environment:
– normal; see clause B.2
RF channels to be tested for single carrier:
– M; see clause 4.12.1.
7.8.4.2 Procedure
The minimum requirement is applied to all TAB connectors, the procedure is repeated until all TAB connectors necessary to demonstrate conformance have been tested; see clause 7.1.
1) Connect TAB connector to measurement equipment as shown in annex D.2.5. All TAB connectors not under test shall be terminated.
For each supported E-UTRA channel BW:
2) Adjust the signal generator for the wanted signal as specified in table 7.8.5-1 for AAS BS of Wide Area BS class, in table 7.8.5-2 for AAS BS of Local Area BS class and in table 7.8.5-3 for AAS BS of Medium Range BS class on one side of the FC.
3) Adjust the signal generator for the interfering signal as specified in table 7.8.5-1 for AAS BS of Wide Area BS class, in table 7.8.5-2 for AAS BS of Local Area BS class and in table 7.8.5-3 for AAS BS of Medium Range BS class at opposite side of the FC and adjacent to the wanted signal.
4) Measure throughput.
5) Repeat the measurement with the wanted signal on the other side of the FC, and the interfering signal at opposite side of the FC and adjacent to the wanted signal.
In addition, for multi-band TAB connector(s), the following steps shall apply:
6) For multi-band TAB connectors and single band tests, repeat the steps above per involved band where single band test configurations and test models shall apply with no carrier activated in the other band.
7.8.5 Test requirements
For each measured E-UTRA carrier, the throughput shall be ≥ 95% of the maximum throughput of the reference measurement channel as specified in [Annex A] with parameters specified in table 7.8.5-1 for AAS BS of Wide Area BS, class in Table7.8.5-2 for AAS BS of Local Area BS class and in table 7.8.5-3 for AAS BS of Medium Range BS class.
