Question: For a UE that transmitted a PSSCH scheduled by a SCI format 2-A with Cast type indicator field value of "01", how does it report HARQ-ACK information to higher layers if it receives multiple PSFCHs associated with different UE identities?
Option 1: Always report an ACK value for all UE identities if at least one PSFCH reception occasion indicates an ACK.
Option 2: Report a NACK value for all UE identities if any PSFCH reception occasion indicates a NACK.
Option 3: Report an ACK value to higher layers if the UE determines an ACK value from at least one PSFCH reception occasion for each UE identity; otherwise, report a NACK value for that UE identity.
Option 4: Combine all HARQ-ACK information into a single report, prioritizing ACK over NACK.
Explanation: According to the specified behavior for SCI format 2-A with Cast type indicator field value of "01", the UE reports an ACK value to higher layers if it determines an ACK value from at least one PSFCH reception occasion across all UE identities' corresponding PSFCH resources; otherwise, it reports a NACK value. This approach ensures that the reporting is done on a per-UE identity basis, considering multiple PSFCH receptions. Option 3 accurately reflects this nuanced behavior, requiring a detailed understanding of how HARQ-ACK information is generated and reported in the context of SCI format 2-A with "01" Cast type indicator field value.
