Abstract: A method and apparatus for hybrid automatic repeat request (HARQ) transmission using timers for configured grants and discontinuous reception (DRX) is provided. A first wireless device operating in a wireless communication system receives, from a second wireless device, a sidelink HARQ feedback for a media access control (MAC) protocol data unit (PDU) on a physical sidelink feedback channel (PSFCH), and starts a DRX HARQ round trip time (RTT) timer for a HARQ process ID after end of reception of the sidelink HARQ feedback. Upon expiry of the DRX HARQ RTT timer, the first wireless device starts a DRX retransmission timer, and monitors a physical downlink control channel (PDCCH) carrying a sidelink retransmission grant during an active time including a time interval for which the DRX retransmission timer is running.

Abstract: Suggested is a novel condition for a media access control (MAC) entity in user equipment (UE) reselecting a sidelink resource in a wireless communication system. The MAC entity of the UE can reselect a sidelink resource when a configured sidelink grant does not satisfy a latency requirement according to ProSe per-packet priority (PPPP). More particularly, configuration is performed by an upper layer so that the MAC entity transmits on the basis of sensing using a resource pool; the MAC entity selects generation of a configured sidelink grant corresponding to transmission of a plurality of MAC protocol data units (PDU); and when data is available in a sidelink traffic channel (STCH) and the configured sidelink grant does not satisfy the latency requirement according to the PPPP, a sidelink resource is reselected.
