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

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.

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 clearing a part of a sidelink grant in a wireless communication system is provided. A first wireless device reserves a set of resources comprising at least a first resource and a second resource for sidelink transmission to a second wireless device, and receives, from a third wireless device, sidelink control information (SCI) which schedules sidelink transmission from the third wireless device. When (i) priority of the sidelink transmission from the third wireless device is higher than priority of the sidelink transmission to the second wireless device, (ii) reference signal received power (RSRP) measurement for the received SCI is higher than a threshold, and (iii) a resource for the sidelink transmission from the third wireless device overlaps with the first resource, the first wireless device clears the first resource from the set of resources, and adds a third resource to the set of resources.
