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.

Abstract: An embodiment proposes a method for performing wireless communication by a first device. The method may comprise a step of receiving information related to a configured grant (CG) from a base station, the information related to the CG including information related to a hybrid automatic repeat request (HARQ) process ID for the CG, and period information of a resource related to the CG, and transmitting a first transport block to a second device at a first period on the basis of the period information and a first HARQ process ID. For example, on the basis that transmission of the first transport block fails, and the first HARQ process ID and a second HARQ process ID are the same, a discontinuous reception (DRX) timer related to the first transport block may be stopped at a second period related to the second HARQ process ID. For example, DRX related to the first transport block may include DRX between the first device and the base station and DRX between the first device and the second device.
