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.

Abstract: A method and apparatus for transmitting positioning information in sidelink communication system is provided. A first wireless device determines positioning information of the first wireless device based on a position of the first wireless device. A first wireless device split the positioning information into first positioning information and second positioning information. A first wireless device transmits, to a second wireless device, the first positioning information via sidelink control information (SCI). A first wireless device transmits, to the second wireless device, the second positioning information via a data unit.

Abstract: A method and apparatus for selecting a destination based on hybrid automatic repeat request (HARQ) feedback in a wireless communication system is provided. A first wireless device selects a destination, from multiple destinations, having a first logical channel with a highest priority among multiple logical channels having data available for transmission. The HARQ feedback is disabled for the first logical channel. The first wireless device selects one or more second logical channels not configured with the HARQ feedback among the multiple logical channels.
