Section: 8.1.2.12 Applicability of performance requirements for 8Rx capable UEs
Content: For 8Rx capable UEs, the 2Rx supported RF bands, 4Rx supported RF bands and 8Rx supported RF bands are up to UE’s declaration. For any demodulation tests and CSI tests conducted in the 8Rx supported RF band, four receive antenna ports that UE may use for control channel demodulation are clarified via UE declaration. When testing an N-Rx (N = 2,4) demodulation or CSI test on the 8Rx supported band, the fading duplication and antenna mapping should guarantee that the four receive antennas UE declares for the control channel demodulation collectively receives at least 4/N duplicated version of the fading channel seen at each receive antenna of the N-Rx test, i.e., the connection diagrams in Figure 8.1.2.12.1-1 to Figure 8.1.2.12.1-4 are valid under the condition that Rx1, Rx3, Rx5 and Rx7 are the four receive antennas declared by UE for the control channel demodulation.
