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: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for forwarding system information for a remote UE by a relay UE in wireless communication system, the method comprising: establishing a link between a remote UE and the relay UE for communicating between the remote UE and the network via the relay UE; receiving assistance information including a serving cell identity of the remote UE from the remote UE; checking whether a serving cell identity of the relay UE and the serving cell identity of the remote UE are same or not; and forwarding system information block (SIB), which was already received by the relay UE from the network, to the remote UE via the link if the serving cell identity of the relay UE and the serving cell identity of the remote UE are different. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

Abstract: Provided are a method for a user equipment (UE) to request system information in a wireless communication system and a device supporting the same. The method may include: transmitting a random access preamble for requesting system information to a base station (BS); receiving, from the BS, a random access response including only a random access preamble identifier (RAPID) corresponding to the transmitted random access preamble; and considering that a random access procedure is completed.

Abstract: A method and apparatus for flushing a hybrid automatic repeat request (HARQ) buffer in a wireless communication system is provided. A user equipment (UE) receives information on multiple resource pools from a network, selects a first resource pool among the multiple resource pools, and stores a media access control (MAC) protocol data unit (PDU) in the HARQ buffer for transmission via the first resource pool. When the UE reselects a second resource pool among the multiple resource pools, the UE flushes the HARQ buffer.

Abstract: A method for a terminal to determine whether or not to suspend a radio bearer in a wireless communication system and a device supporting the method are provided. The method may comprise: a step of receiving, from a base station, a configuration indicating if data transmission through a certain radio bearer is permitted in an RRC_INACTIVE state; a step of entering the RRC_INACTIVE state; and a step of determining, based on the configuration, whether or not to suspend the certain radio bearer in the RRC_INACTIVE state.

Abstract: Provided are a method for a terminal requesting a radio resource control (RRC) connection in a wireless communication system, and a device supporting same. The method may comprise the steps of: receiving a UE ID from a first cell; determining whether the UE ID is valid; and transmitting an RRC connection resume request message including the UE ID to a second cell if the terminal determines that the UE ID is valid.

Abstract: A method and apparatus for allocating resources for a sidelink transmission in a wireless communication system is provided. A user equipment (UE) selects a first carrier, i.e. anchor carrier, among multiple carriers, and allocates a first resource on the first carrier. The UE allocates a second resource on a second carrier, i.e. non-anchor carrier, based on an offset from the first resource on the first carrier. The UE performs the sidelink transmission by using the first resource on the first carrier and the second resource on the second carrier.
