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 of operating the first apparatus 100 in a wireless communication system is proposed. The method may include: performing resource selection for at least one period, wherein each of the at least one period includes at least one transmission resource; increasing a value related to a consecutive unused transmission opportunity by 1, based on that transmission is not performed on all transmission resources within a first period included in the at least one period; and triggering resource reselection based on that the value related to a consecutive unused transmission opportunity reaches a threshold value related to a consecutive unused transmission opportunity.

Abstract: Presented is a method by which a first device performs wireless communication. The method may comprise the steps of: reevaluating a first transmission resource for performing sidelink communication; reselecting the first transmission resource on the basis of the reevaluation; and reselecting a second transmission resource on the basis of the reselection of the first transmission resource. For example, the second transmission resource may be a resource that is selected by the first device before the first transmission resource is reselected. For example, the second transmission resource may be a resource that is not reserved by the first device.

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.
