Abstract: A method and apparatus for resource selection for multiple hybrid automatic repeat request (HARQ) processes in a wireless communication system is provided. A wireless device, which is configured with one or more resource pools for autonomous resource selection, determines a number of sidelink processes, and generates a selected sidelink grant for the determined number of the sidelink processes. The wireless device triggers a sidelink resource reselection based on a resource mapped to a specific sidelink process from among the sidelink processes, and reselects sidelink resources mapped to the specific sidelink process from the selected sidelink grant.

Abstract: A method and apparatus for resource allocation for sidelink configured grant is provided. A first wireless device receives, from a network, a cell specific Uplink (UL)-Downlink (DL) Time Division Duplex (TDD) configuration and considers that a first slot of a specific sidelink grant occurs in a logical slot determined based on a periodicity. The periodicity is determined based on a number of slots related to sidelink transmission, and the number of slots is determined based on the cell specific UL-DL TDD configuration.

Abstract: A method and apparatus for allocation of Hybrid Automatic Repeat request (HARQ) identifiers (IDs) to different User Equipments (UEs) and/or different destinations is provided. A wireless device initializes or re-initializes a configured sidelink grant to determine Physical Sidelink Control Chanel (PSCCH) durations and Physical Sidelink Shared Channel (PSSCH) durations based on a Configured Grant (CG) time offset, and to reoccur with an CG period for transmissions of multiple Media Access Control (MAC) Protocol Data Units (PDUs). The CG time offset is an offset of a resource with respect to a particular System Frame Number (SFN) value and defined as the number of logical slots that can be included in a sidelink resource pool.

Abstract: A method and apparatus for bandwidth parts (BWPs) deactivation and discontinuous reception (DRX) for communication between wireless devices is provided. A first wireless device operating in a wireless communication system performs transmission of a media access control (MAC) protocol data unit (PDU) to a second wireless device, and starts a discontinuous (DRX) hybrid automatic repeat request (HARQ) round trip time (RTT) timer for a HARQ process ID after end of a specific repetition of the transmission of the MAC PDU. The first wireless device starts a DRX retransmission timer based on 1) the DRX HARQ RTT timer being expired, and 2) a number of transmissions of the MAC PDU not reaching a maximum number of transmissions, 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: Provided are a method by which a first device performs wireless communication, and a device supporting same. The method may comprise the steps of: receiving sidelink control information (SCI) including scheduling information for a physical sidelink shared channel (PSSCH) from a second device through a physical sidelink control channel (PSCCH), wherein the SCI includes information related to frequency resource allocation, information related to time resource allocation, information related to a demodulation reference signal (DMRS) pattern, and information related to a modulation and coding scheme (MCS); receiving first auxiliary information from the second device through the PSSCH; selecting at least one sidelink (SL) resource on the basis of at least one of at least one SCI or the first auxiliary information; performing resource reselection for the at least one SL resource; and transmitting an auxiliary information request to the second device on the basis of the resource reselection.

Abstract: A method and apparatus for media access control (MAC) reset for radio resource control (RRC) connection between wireless devices is provided. A wireless device operating in a wireless communication system triggers a scheduling request (SR) based on a triggered sidelink (SL) buffer status report (BSR) and/or SL channel state information (CSI) reporting. Based on a media access control (MAC) reset being requested, by an upper layer of the wireless device, for one PC5-RRC connection among one or more PC5-RRC connections, the wireless device cancels any SR only associated to the one PC5-RRC connection.

Abstract: A method and apparatus for hybrid automatic repeat request (HARQ) transmissions for configured grants (CGs) in a wireless communication system is provided. A first wireless device receives a retransmission resource for a HARQ process identifier (ID) for a CG. When a number of transmissions of a media access control (MAC) protocol data unit (PDU) does not reach to a maximum number of transmissions, the first wireless device performs retransmission of the MAC PDU to a second wireless device by using the retransmission resource. When the number of transmissions of the MAC PDU reaches to the maximum number of transmissions, the first wireless device flushes a HARQ buffer in a sidelink process.

Abstract: A method and apparatus for indicating sidelink (SL) radio link failure (RLF) in a wireless communication system is provided. A first wireless device may initialize the counter to zero upon 1) establishing the PC5-RRC connection with the second wireless device, or 2) configuring or reconfiguring the maximum number of the counter. A first wireless device may increase the counter based on no reception of any acknowledgement to the transmission of the MAC PDU. A first wireless device may indicate Sidelink (SL) Radio Link Failure (RLF) for the PC5-RRC connection based on that the counter reaches the maximum number of the counter.
