A.3.3 Test Equipment Parts for Radiated Measurements
38.508-13GPP5GSPart 1: Common test environmentRelease 17TSUser Equipment (UE) conformance specification
A.3.3.1 Transmitter/Receiver tests
The Test Equipment part is focused on logical representation of TE measurement and link antenna(s) and positioner controller. The Test Equipment connection diagram below is applicable for NR radiated RX and TX tests, including CA and UL MIMO tests.

A.3.3.2 Demodulation and CSI tests
Figure A.3.3.2.1: Demodulation and CSI tests
Figures A.3.3.2.1-1 and A.3.3.2.1-1 show the connection diagram inside SS NR of Figure A.3.3.2.1 for downlink signal path.

A.3.3.3 RRM tests
The Test Equipment part is focused on logical representation of TE antenna(s) and positioner. The Test Equipment connection diagram below is applicable for NR radiated RRM tests. SS NR uses several antennas to cover all required AoA offsets. The actual number of antennas is not determined and depends on the TE implementation. Positioner in the TE part is optional.
Figure A.3.3.3.1: TE diagram for radiated RRM tests
Figure A.3.3.3.1-1 shows the connection diagram inside the SS NR of Figure A.3.3.3.1 for downlink signal path (for single probe). 1×2 without fading in FR2 RRM test case represents the scenario with single antenna transmission from TE side and 2 antenna receptions at UE side, which is equivalent to 1×1 in conducted test case from test equipment perspective.
