Abstract: A method of performing an operation for a first user equipment (UE) in a wireless communication system includes determining a slot for transmitting a physical uplink control channel (PUCCH) based on a value related to the number of slots from a physical sidelink feedback channel (PSFCH) to the PUCCH by the first UE, and transmitting, to a base station (BS), feedback information based on the PSFCH through the PUCCH in the slot by the first UE. The value related to the number of slots is applied based on a last of slots for the PUCCH, overlapped with a slot for the PSFCH on a time axis.
