7.8 OTA Receiver intermodulation

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

7.8.1 Definition and applicability

Third and higher order mixing of the two interfering RF signals can produce an interfering signal in the band of the desired channel. Intermodulation response rejection is a measure of the capability of the receiver unit to receive a wanted signal on its assigned channel frequency in the presence of two interfering signals which have a specific frequency relationship to the wanted signal.

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:

– when the wanted signal is based on EISREFSENS : the AoA of the incident wave of a received signal and the interfering signal are within the OTA REFSENS RoAoA.

– when the wanted signal is based on EISminSENS : the AoA of the incident wave of a received signal and the interfering signal are within the minSENS RoAoA.

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

7.8.2 Minimum Requirement

For AAS BS in MSR operation the minimum requirement is defined in TS 37.105 [6], clause 10.8.2.

For AAS BS in single RAT UTRA operation the minimum requirement is defined in TS 37.105 [6], clause 10.8.3.

For AAS BS in single RAT E-UTRA operation the minimum requirement is defined in TS 37.105 [6], clause 10.8.4.

7.8.3 Test purpose

The test purpose is to verify the ability of the receiver to inhibit the generation of intermodulation products in its non-linear elements caused by the presence of two high-level interfering signals at frequencies with a specific relationship to the frequency of the wanted signal.

7.8.4 Method of test

7.8.4.1 Initial conditions

Test environment: normal; see annex G.2.

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

Base Station RF Bandwidth positions to be tested: For single-band RIB(s): MRFBW if ATC4 is applicable; BRFBW and TRFBW for other ATC, see clause 4.12.1. For multi-band RIB(s): BRFBW_T’RFBW and B’RFBW_TRFBW, see clause 4.12.1.

Directions to be tested: OTA REFSENS receiver target reference direction (see table 4.10-20 D11.30).

7.8.4.2 Procedure

7.8.4.2.1 General procedure

The general procedure steps apply to the procedures for all the RATs.

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 D2.6.

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.

5) Configure the beam peak direction of the AAS BS according to declared reference beam direction pair for the appropriate beam identifier.

6) Set the AAS BS to transmit the beam(s) of the same operational band and RAT as the OSDD being tested according to the appropriate test configuration in clause 5.

7) Set the test signal mean power so the calibrated radiated power at the AAS BS Antenna Array coordinate system reference point is as specified as follows:

Set the signal generator for the wanted signal according to the applicable test configuration (see clause 5) using applicable reference measurement channel to transmit:

– For E-UTRA see clause A.1 in TS 36.141 [12].
