Abstract: Provided are a method of performing cell reselection and a device supporting the method. According to one embodiment of the present disclosure, the method includes: starting data transmission or data reception while the UE is in radio resource control (RRC) idle state or RRC inactive state; applying an offset value to a serving cell for cell reselection; performing cell reselection based on the applied offset value, during the data transmission or data reception; and stopping applying the offset value to the serving cell, when the data transmission or data reception is succeeded.

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.

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 confirmation of multiple configured grants for sidelink in a wireless communication system is provided. A wireless device receives activation command or deactivation command on Physical Downlink Control Channel (PDCCH) for at least one of the multiple configured grants. A wireless device receives transmits, to the network, a confirmation Media Access Control (MAC) Control Element (CE). The confirmation MAC CE includes one or more fields in a bit group of which size is equal to number of the multiple configured grants. Each field in the bit group is set to (i) zero to indicate deactivation for each of the multiple configured grants or (ii) 1 to indicate activation for each of the multiple configured grants. Each field in the confirmation MAC CE except the bit group is ignored.
