    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: A method for performing wireless communication by a first device and an apparatus supporting the same are proposed. For example, the first device may obtain an SL DRX configuration including information related to an SL DRX cycle and information related to a timer for active time. For example, the timer for active time may include at least one of an SL DRX on-duration timer or an SL DRX inactivity timer. For example, the first device may trigger SL DRX command MAC CE reporting related to the PC5-RRC connection. For example, the first device may cancel the triggered SL DRX command MAC CE reporting, based on an MAC reset for the PC5-RRC connection being requested.
