1. A method for performing, by a first apparatus, wireless communication, the method comprising:
receiving a plurality of first physical sidelink control channels (PSCCHs);
receiving a plurality of first physical sidelink shared channels (PSSCHs) related to the plurality of first PSCCHs;
transmitting a plurality of second PSCCHs;
transmitting a plurality of second PSSCHs related to the plurality of second PSCCHs; and
transmitting a first physical sidelink feedback channel (PSFCH), among a plurality of first PSFCHs related, respectively, to the plurality of received first PSSCHs, or receiving a second PSFCH, among a plurality of second PSFCHs related, respectively, to the plurality of transmitted second PSSCHs, based on an overlap in a time for transmitting a plurality of first PSFCHs related, respectively, to the plurality of received first PSSCHs and a time for receiving a plurality of second PSFCHs related, respectively, to the plurality of transmitted second PSSCHs,
wherein each of the plurality of first PSFCHs has a corresponding priority and each of the plurality of second PSFCHs has a corresponding priority, and
wherein transmitting the first PSFCH or receiving the second PSFCH is based on the priority of the first PSFCH and the priority of the second PSFCH.
