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.

Abstract: In vehicle-to-everything (V2X) communication or vehicle-to-pedestrian (V2P) communication, a first user equipment (UE) transmits, at a transmission timing, first data for a specific logical channel, and determines a reception timing window on the basis of the transmission timing. A second UE transmits second data in a specific time interval that is within the reception timing window or is prior to the reception timing window, and the first UE monitors the reception timing window in order to receive the second data.

Abstract: Provided are a method for keeping, by a user equipment (UE), a first dual connectivity (DC) configuration in a wireless communication system. The method may include: receiving information for validation of a DC configuration, from a network, wherein the DC configuration includes the first DC configuration and a second DC configuration; determining whether or not the first DC configuration is valid in a radio resource control (RRC) resume procedure, based on the information for validation of DC configuration; if the first DC configuration is valid, keeping the first DC configuration in an RRC resume procedure; and releasing the second DC configuration before initiating the RRC resume procedure.

Abstract: Disclosed are a method for performing V2X communication in a wireless communication system and an apparatus for the same. Specifically, a method for performing vehicle-to-everything (V2X) communication by a user equipment (UE) in a wireless communication system includes: receiving a transmission request of a V2X message of a V2X service identified by a V2X service identifier from an upper layer by using V2X communication through a PC5 interface, the transmission request including the V2X message and the V2X service identifier; requesting or selecting a resource for the V2X communication through the PC5 interface to a base station based on whether the UE is serviced by an evolved universal terrestrial radio access network (E-UTRAN) for the V2X communication; and transmitting the V2X message through the PC5 interface by transferring the V2X message to a lower layer, and when mapping between the V2X service identifier and a transmission parameter is configured, the transmission parameter associated with the V2X service identifier may be transferred to the lower layer together with the V2X message.
