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 reconfiguration of sidelink configuration and sidelink resource allocation in a wireless communication system is provided. Upon leaving a connected state and entering a new state, while in the new state, a first wireless device configured to operate in a wireless communication system keeps performing sidelink transmission to a second wireless device based on a first sidelink configuration received via dedicated signaling, receives, from a network via broadcast signaling, a second sidelink configuration, and performs the sidelink transmission to the second wireless device based on the second sidelink configuration.

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: Provided are a method for a first device carrying out wireless communication, and an apparatus supporting same. The method may comprise the steps of: transmitting sidelink control information (SCI) to a second device via a physical sidelink control channel (PSCCH); transmitting data to the second device via a physical sidelink shared channel (PSSCH) which is associated with the PSCCH; determining a physical sidelink feedback channel (PSFCH) resource on the basis of a slot and subchannel associated with the PSSCH: increasing a DTX counter by one on the basis of failing to receive hybrid automatic repeat request (HARQ) feedback on the PSFCH resource; receiving, from the second device, information related to dropping the transmission of the HARQ feedback; and decreasing the DTX counter by N on the basis of the information related to dropping the transmission of the HARQ feedback. Sidelink (SL) radio link failure (RLF) may be declared on the basis that the DTX counter reaches the maximum number of DTXs, and N may be a positive integer.

Abstract: Provided, according to one embodiment of the present disclosure, is a method for a first device carrying out sidelink communication. The method comprises the steps of: starting a first timer associated with a PSFCH resource on the basis that sidelink HARQ feedback information is not transmitted to a second device through the PSFCH resource on the basis of a first priority associated with the sidelink HARQ feedback information; on the basis that the first timer has expired, starting a second timer associated with a sidelink HARQ retransmission packet for a PSSCH or SCI; and receiving the sidelink HARQ retransmission packet from the second device after the second timer starts.

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: 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.
