To test PSCCH or PSSCH performance requirements the UE under test is required to send sidelink HARQ feedback on PSFCH based on corresponding PSSCH reception when PSFCH is configured in resource pool and sidelink HARQ function is enabled. The SS can use the PSFCH sent by the UE under test to determine a Pass or Fail decision. See G.5.2 for more details.

To test PSFCH performance requirements. PSFCH should be configured in resource pool and sidelink HARQ function should be enabled. The UE under test is required to keep sending PSSCH transport blocks when test loop function mode E (transmit mode) is activated as specified in TS 38.509 [22]. The SS shall sends appropriate sidelink HARQ feedback on PSFCH corresponds to each PSSCH. The UE shall retransmit PSSCH if it receives NACK on corresponding PSFCH. The SS can use the re-transmission sent by the UE under test to determine a Pass or Fail decision. See G.5.3 for more details.

The system simulator (SS) sends NR sidelink packets or PSFCH to the UE under test. The number of packets or PSFCH sent by the SS is predefined by the test time in G.5.4, G.5.5 and G.5.6 for requirements with PSSCH throughput, PSCCH miss-detection probability, and PSFCH miss-detection probability, respectively.
