Abstract: Proposed is an operation method of a first device (100) in a wireless communication system. The method may comprise the steps of: establishing a sidelink (SL) unicast link with a second device (200); transmitting first SL discontinuous reception (DRX) configuration information related to the SL unicast link to the second device (200); transmitting a physical sidelink control channel (PSCCH) to the second device (200) in an on-duration interval included in the first SL DRX configuration information; and transmitting a physical sidelink shared channel (PSSCH) to the second device (200) on the basis of the PSCCH in the on-duration interval.

Abstract: A method and apparatus for periodic transmissions for a configured grant is provided. A first device operating in a wireless communication system transmits, to a second device, a media access control (MAC) protocol data unit (PDU) by using a first resource of a configured grant (CG) in a first period for which the first resource of the CG is associated with a HARQ process identifier (ID), and flushes a HARQ buffer associated with the HARQ process ID in a second period for which a second resource of the CG is associated with the HARQ process ID. Then, the first device ignores a retransmission resource associated with the HARQ process ID based on flushing the HARQ buffer.

Abstract: A method and apparatus for sidelink resource allocation and media access control (MAC) reset is provided. A wireless device, which is configured with network scheduled resource allocation for sidelink, sets new data indicators (NDIs) for all hybrid automatic repeat request (HARQ) process identifiers (IDs) specific to the sidelink to value 0, based on a media access control (MAC) reset being requested by an upper layer of the wireless device.

Abstract: A method for performing wireless communication by a first device and an apparatus for supporting same are provided. The method may comprise: receiving, from a base station, information related to a first sidelink (SL) resource and information related to a first physical uplink control channel (PUCCH) resource; transmitting, to a second device, a medium access control (MAC) packet data unit (PDU) by using the first SL resource, wherein the MAC PDU includes a packet related to a logical channel for which hybrid automatic repeat request (HARQ) feedback is disabled, and wherein the MAC PDU includes no packet related to a logical channel for which HARQ feedback is enabled; determining that retransmission of the MAC PDU is required; and transmitting, to the base station, NACK information by using the first PUCCH resource based on no SL grant available for retransmission of the MAC PDU.

Abstract: Proposed is a method for performing, by a first apparatus, wireless communication. The method may receive, from a base station, information associated with a first sidelink (SL) resource, generate a medium access control protocol data unit (MAC PDU) including a sidelink packet in which hybrid automatic repeat request (HARQ) feedback is enabled on the basis of a logical channel priority (LCP), and reselect a second SL resource for transmitting the MAC PDU.
