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.

Abstract: A method and apparatus for deprioritizing access on an unlicensed band based on user equipment (UE) preference in a wireless communication system is provided. A wireless device attempts to access a cell on an unlicensed frequency and starts a timer. When the timer expires, if the wireless device is a licensed preferred wireless device, the wireless device deprioritizes the unlicensed frequency. If the wireless device is an unlicensed preferred wireless device, the wireless device deprioritizes only the cell. The wireless device performs a cell reselection according to the de-prioritization.

Abstract: A method and apparatus for performing an uplink (UL) transmission with pre-allocated beams in a wireless communication system is provided. A user equipment (UE) receives a connection release message from a network in a first state. The connection release message includes information on a pre-allocated UL resource for UL transmission with pre-allocated beams. The UE enters a second state from the first state, selects a cell, and performs the UL transmission to the cell in the second state via the pre-allocated beams based on the pre-configured UL resource for UL transmission when a data is available for transmission. The first state may be a radio resource control (RRC) connected state, and the second state may be an RRC inactive state and/or an RRC idle state.
