Abstract: A method of performing an operation for a first user equipment (UE) in a wireless communication system includes transmitting a physical sidelink shared channel (PSSCH) to a second UE by the first UE, and transmitting, to a base station (BS), feedback information based on a physical sidelink feedback channel (PSFCH) for the PSSCH on a physical uplink control channel (PUCCH) by the first UE. A transmission timing of the PUCCH is determined based on information about the number of slots from the PSFCH to the PUCCH.
