G.1 Measurement Point

38.101-23GPPNRPart 2: Range 2 StandaloneRelease 17TSUser Equipment (UE) radio transmission and reception

Figure G.1-1 shows the measurement point for the difference of relative phase and power errors. To separate signals from the two transmitters, it is necessary for the test equipment to perform joint demodulation by inverting the 2×2 composite channel (‘HGW’) resulting from DUT precoding ‘W’ and antenna virtualization ‘G’ and OTA channel between DUT and test equipment ‘H’.
