Question: When a UE would simultaneously transmit and receive PSFCHs (Physical Shared Feedback Channels) with overlapping timings, how does it determine which set of PSFCHs to prioritize?
Option 1: Based on the largest priority field value indicated by the associated SCI (Scheduling Control Information) format 1-A.
Option 2: Based on the smallest priority field value determined by the first and/or second set of SCI format 1-A associated with PSFCHs providing HARQ-ACK information or conflict information.
Option 3: Randomly selecting one set of PSFCHs to ensure fairness between transmissions and receptions.
Option 4: Always prioritizing the transmission of PSFCHs over their reception.
Explanation: This is because, according to the specified procedure for handling simultaneous PSFCH transmission/reception with overlapping timings, the UE prioritizes based on the smallest priority field value. This ensures that the most critical information (either HARQ-ACK or conflict information, as indicated by SCI format 1-A) is handled first, maintaining efficient communication and minimizing potential errors or conflicts in the network.
