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 sate 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.

Abstract: Provided are a method for transmitting a multimedia broadcast multicast service (MBMS) interest indication message by a terminal in a wireless communication system and an apparatus for supporting the same. The method may comprise the steps of: receiving MBMS scheduling information from a base station; selecting at least one beam among a plurality of beams; on the basis of the MBMS scheduling information, determining whether an MBMS service of interest is provided via the at least one selected beam; and when the terminal determines that the MBMS service of interest is not provided via the at least one selected beam, transmitting, to the base station, an MBMS interest indication message including the MBMS service of interest and the at least one selected beam.

Abstract: The present disclosure relates to logical channel prioritization (LCP) in wireless communications. According to an embodiment of the present disclosure, a method performed by a first wireless device in a wireless communication system comprises: creating a media access control (MAC) protocol data unit (PDU); and transmitting the MAC PDU to a second wireless device, wherein the MAC PDU includes at least one of data from sidelink control channel (SCCH), a MAC control element (CE) for sidelink (SL) feedback information, or data from sidelink transmission channel (STCH) according to a logical channel prioritization (LCP), wherein the data from SCCH including one or more PC5-signalling (PC5-S) messages has a higher priority to be included in the MAC PDU than the MAC CE for SL feedback information, and wherein the MAC CE for SL feedback information has a higher priority to be included in the MAC PDU than the data from STCH.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing a LCP procedure by a Relay UE in wireless communication system, the method comprising: performing, by the relay UE, a LCP procedure for generating MAC PDU by considering a priority of a first logical channel of a remote UE and a priority of a second logical channel of the relay UE; and transmitting the MAC PDU to a network, wherein if the priority of the second logical channel is equal to the priority of the first logical channel, data from the second logical channel of the relay UE is prioritized over data from the first logical channel of the remote UE during the LCP procedure.

Abstract: As a channel busy ratio (CBR) is defined to measure the congestion of a PC5 interface in order to support an effective vehicle-to-everything (V2X) communication, an eNodeB (eNB) transmits CBR information of a sidelink channel to a user equipment (UE) for each resource pool used for V2X communication. The user equipment which has received the CBR information determines if there is a usable CBR and, if it is determined that there is no usable CBR, can use the received CBR information.
