7.9 OTA In-channel selectivity

37.145-23GPPActive Antenna System (AAS) Base Station (BS) conformance testingPart 2: radiated conformance testingRelease 17TS

7.9.1 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 at the RIB when the AoA of the incident wave of a received signal and the interfering signal are from the same direction and are within the minSENS RoAoA.

The wanted and interfering signals apply to each supported polarization, under the assumption of polarization match.

7.9.2 Minimum Requirement

For AAS BS in MSR operation the minimum requirement is defined in TS 37.105 [6], clause 10.9.2.

For AAS BS in single RAT UTRA operation the minimum requirement is defined in TS 37.105 [6], clause 10.9.3.

For AAS BS in single RAT E-UTRA operation the minimum requirement is defined in TS 37.105 [6], clause 10.9.4.

7.9.3 Test purpose

The purpose of this test is to verify the ability of the receiver to suppress the IQ leakage.

7.9.4 Method of test

7.9.4.1 Initial conditions

Test environment: normal; see annex G.2

RF channels to be tested for single carrier: M; see clause 4.12.1.

Directions to be tested: OTA REFSENS receiver target reference direction (see table 4.10-2, D11.30).

7.9.4.2 Procedure

1) Place the AAS BS with its manufacturer declared coordinate system reference point in the same place as calibrated point in the test system, as shown in Annex D1.1.

2) Align the manufacturer declared coordinate system orientation of the AAS BS with the test system.

3) Align the BS with the test antenna in the declared direction to be tested.

4) Align the NR BS to that the wanted signal and interferer signal is polarization matched with the test antenna(s)

For each supported E-UTRA channel BW:

5) Adjust the signal generator for the wanted signal as specified in table 7.9.5.1-1 for AAS BS of Wide Area BS class, in table 7.9.5.1-2 for AAS BS of Local Area BS class and in table 7.9.5.1-3 for AAS BS of Medium Range BS class on one side of the FC.

6) Adjust the signal generator for the interfering signal as specified in table 7.9.5.1-1 for AAS BS of Wide Area BS class, in table 7.9.5.1-2 for AAS BS of Local Area BS class and in table 7.9.5.1-3 for AAS BS of Medium Range BS class at opposite side of the FC and adjacent to the wanted signal.

7) Measure throughput according to annex E in TS 36.141 [12].

8) 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.

9) Repeat for all supported polarizations. 10

For each supported NR channel BW:

2) Adjust the signal generator for the wanted signal as specified in table 7.9.5.2-1 for AAS BS of Wide Area BS class, in table 7.9.5.2-2 for AAS BS of Local Area BS class and in table 7.9.5.2-3 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 7.9.5.2-1 for AAS BS of Wide Area BS class, in table 7.9.5.2-2 for AAS BS of Local Area BS class and in table 7.9.5.2-3 for AAS BS of Medium Range BS class at opposite side of the FC and adjacent to the wanted signal.

4) Measure throughput according to annex A in TS 38.141-2 [34].

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 RIB(s), the following steps shall apply:

10) For multi-band RIBs 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.

7.9.5 Test Requirement

7.9.5.1 E-UTRA test requirement
