Abstract: Presented in one embodiment is a method by which a first device performs wireless communication. The method may comprise the steps of: acquiring a sidelink discontinuous reception (SL DRX) configuration; receiving, from a second device, first sidelink control information (SCI) for scheduling a first physical sidelink shared channel (PSSCH) through a first physical sidelink control channel (PSCCH); receiving, from the second device, second SCI and first data through the first physical sidelink shared channel (PSSCH); and determining a first physical sidelink feedback channel (PSFCH) resource on the basis of a slot index and a sub-channel index, which are related to the first PSSCH. For example, a first timer included in the SL DRX configuration can be initiated on the basis of the omission of a first PSFCH transmission related to the first PSSCH on the first PSFCH resource.
