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.

Abstract: A disclosure of the present specification provides a method for transmitting data by a transmitter. The method may comprise the steps of: when a transport block (TB) is divided into n data blocks, adding additional information after each of the n data blocks; and adding a cyclic redundancy check (CRC) after the last additional information. Here, the CRC may be generated on the basis of the n data blocks, and the n pieces of additional information added after each of data blocks.
