    摘要： A method for performing wireless communication by a first device and a device supporting same are provided. The method may comprise the steps of: acquiring information related to a set of resource blocks (RBs) for a physical sidelink feedback channel (PSFCH); transmitting first sidelink control information (SCI) for scheduling of second SCI and a physical sidelink shared channel (PSSCH) to a second device through a physical sidelink control channel (PSCCH); transmitting data and the second SCI including a source identifier (ID) of the first device to the second device through the PSSCH; allocating at least one RB in the set of RBs to the PSSCH; on the basis of the source ID of the first device, determining an index of a first PSFCH resource for PSFCH reception in the at least one RB; and transmitting information for an active time to the second device on the basis of inability of detecting hybrid automatic repeat request (HARQ) feedback on the first PSFCH resource.

    摘要： Proposed are a method by which a first device performs wireless communication, and an apparatus supporting same. The method may comprise the steps of: acquiring a sidelink (SL) discontinuous reception (DRX) configuration including information related to an SL DRX slot offset and information related to an SL DRX timer; initiating the SL DRX timer; receiving, from a second device via a physical sidelink control channel (PSCCH), second sidelink control information (SCI), and first SC for scheduling of a physical sidelink shared channel (PSSCH); and receiving the second SCI and a medium access control (MAC) protocol data unit (PDU) from the second device via the PSSCH. For example, the second SCI and the SL DRX configuration may be related to a groupcast type or a broadcast type. For example, the SL DRX slot offset may be configured on the basis of information regarding quality of service (QoS).

    摘要： Proposed are a method by which a first device performs wireless communication, and an apparatus supporting same. The method may comprise the steps of: acquiring an SL DRX configuration including an SL DRX inactivity timer, an SL DRX HARQ RTT timer, and an SL DRX retransmission timer, receiving, from a second device through a first PSCCH, first SCI for scheduling of a first PSSCH and second SCI; and receiving the second SCI and a first MAC PDU from the second device through the first PSSCH. For example, the first device may start the SL DRX inactivity timer. For example, the first device may transmit SL HARQ feedback information to the second device through a PSFCH on a PSFCH resource determined on the basis of a slot index and a sub-channel index related to the first PSSCH. For example, the first device may restart the SL DRX inactivity timer after the PSFCH resource on the basis of the second SCI being related to a groupcast.

    摘要： Provided are a method for a first device to perform wireless communication and a device supporting same. The method may comprise the steps of: triggering resource selection in a slot; selecting Y candidate slots in a selection window determined on the basis of the slot; monitoring at least one first slot related to the Y candidate slots; selecting at least one first candidate resource in the Y candidate slots on the basis of at least one reference signal received power (RSRP) value measured on the basis of the monitoring of the at least one first slot and an RSRP threshold; increasing the RSRP threshold by an RSRP step on the basis of the number of the at least one first candidate resource being less than a first threshold number; and selecting N candidate slots from among the slots in the selection window on the basis of the increased RSRP threshold being greater than or equal to a maximum RSRP threshold.

    摘要： A method for performing wireless communication by a first device, and a device supporting same are provided. The method may comprise the steps of: acquiring a sidelink (SL) discontinuous reception (DRX) configuration including information on a timer related to an active time and information related to an SL DRX cycle; determining inactivation of an SL DRX operation; and transmitting, to a second device, information indicating that the SL DRX operation is not supported, wherein the timer related to the active time includes at least one of an SL DRX on-duration timer, an SL DRX inactivity timer, and an SL DRX retransmission timer.
