1. A method of transmitting or receiving a Physical Sidelink Feedback Channel (PSFCH) by a user equipment (UE) in a Vehicle-to-Everything (V2X) communication system, the method comprising:
transmitting a plurality of first Physical Sidelink Shared Channels (PSSCHs);
receiving a plurality of second PSSCHs;
determining (i) first PSFCH resources for receiving a set of first PSFCHs in response to the plurality of first PSSCHs and (ii) second PSFCH resources for transmitting a set of second PSFCHs in response to the plurality of second PSSCHs;
based on the first PSFCH resources being overlapped in time with the second PSFCH resources:
determining a smallest priority value among a plurality of first priority values corresponding to the set of first PSFCHs and a plurality of second priority values corresponding to the set of second PSFCHs;
receiving the set of first PSFCHs based on the set of first PSFCHs corresponding to a smallest priority field value; and
transmitting the set of second PSFCHs based on the set of second PSFCHs corresponding to the smallest priority field value.
