1. A method performed by a first user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a second UE, first-stage sidelink control information (SCI) for a first physical sidelink shared channel (PSSCH), wherein the first-stage SCI includes information for a first priority value associated with a first physical sidelink feedback channel (PSFCH) for the first PSSCH and information for a second-stage SCI;
receiving, from the second UE, the second-stage SCI including hybrid automatic repeat-request (HARQ) feedback enabling information based on the information for the second-stage SCI;
receiving, from the second UE, the first PSSCH based on the first-stage SCI;
transmitting, to the second UE, a second SCI;
transmitting, to the second UE, a second PSSCH based on the second SCI;
identifying a transmission of the first PSFCH for the first PSSCH and a reception of a second PSFCH for the second PSSCH overlap in a time domain; and
transmitting the first PSFCH to the second UE or receiving the second PSFCH from the second UE based on the information for the first priority value associated with the first PSFCH and information for a second priority value associated with the second PSFCH,
wherein whether a HARQ feedback is included in the first PSFCH is based on the HARQ feedback enabling information included in the second-stage SCI.
