The Sidelink UEs receive the PSSCH sent by the UE under test and send PSFCH. Information transmitted in each PSFCH is randomly selected from Option A, Option B and Option C with probability of 50%, 25% and 25% respectively. Transmitted PSFCHs are related to one PSSCH which is transmitted by tested UE and occupies all the subchannels.

– Option A: All the UEs in the group transmit ACKs

– Option B: One UE transmits NACK and the rest of UEs transmit ACKs. The PSFCH resource index with NACK is random per slot

– Option C: One UE transmits nothing (i.e. DTX) and the rest of UEs transmit ACKs. The PSFCH resource index of the DTX is random per slot.

2. Set the parameters of the bandwidth, MCS, reference channel, the propagation condition, the correlation matrix and the SNR according to Table 11.1.9.1_1.1.4‑1 as appropriate.

3. Measure probability of success detection slot with ACK only, and probability of success detection slot with NACK or DTX according to the test method described in Annex G.5 for a duration sufficient to achieve statistical significance. Pass the UE if the measured probability of success detection slot with ACK only, and probability of success detection slot with NACK or DTX are no less than the reference value in Table 11.1.9.1.1_1.4‑1. Otherwise fail the UE.

4. Repeat steps from 1 to 3 for each subtest in Table 11.1.9.1.1_1.4‑1 as appropriate.

11.1.9.1.1_1.4 Test Requirements

For the parameters specified in Table 11.1.9.1.0-1 and SNR specified in Table 11.1.9.1.1_1.4‑1, the probability of success detection slot with ACK only, and probability of success detection slot with NACK or DTX obtained in step 3 shall be no less the reference value specified in Table 11.1.9.1.1_1.4‑1.

Table 11.1.9.1.1_1.4‑1: Test performance requirements

Test Number	Bandwidth (MHz) / Subcarrier spacing(kHz)	Propagation Channel	Reference value
			Probability of success detection slot with ACK only	Probability of success detection slot with NACK or DTX
1	40 / 30	Static propagation condition without external noise	99	99
Note 1: The probability of success detection slot with ACK only is the probability that the corresponding PSSCH is not retransmitted when Option A is selected. Note 2: The probability of success detection slot with NACK or DTX is the probability that the corresponding PSSCH is retransmitted when Option B or option C is selected.
