Abstract: A method and apparatus for selecting a carrier for a sidelink communication in a wireless communication system is provided. A user equipment (UE) receives an indication of an aggregated set of carriers among multiple carriers from the network. The aggregated set of carriers may be aggregated based on a destination of the sidelink communication. The UE selects a carrier among the aggregated set of carriers, selects a resource of the selected carrier, and performs the sidelink communication by using the selected resource of the selected carrier.

Abstract: A method for performing vehicle-to-everything (V2X) communication in a wireless communication system and a device for same are disclosed. Particularly, a method for a user equipment (UE) performing V2X communication by means of a PC5 interface in a wireless communication system comprises the steps of: receiving from an upper layer a request for transmitting a V2X message; requesting radio resources, for V2X communication by means of a PC5 interface, to a base station or selecting radio resources for V2X communication by means of the PC5 interface; and performing transmission of V2X communication by means of the PC5 interface, wherein, if a UE has emergency packet data network (PDN) connection, an indication, indicating that transmission by means of the emergency PDN connection is a higher priority than the V2X communication by means of the PC5 interface, can be transmitted from the upper layer.

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: The present disclosure provides a method for receiving a paging message, by a user equipment (UE) in a radio resource control (RRC) connection suspended state, in a wireless communication system. The method includes receiving the paging message from an evolved Node B (eNB); checking an indicator indicating whether the eNB stores a UE context, wherein the indicator is included in the paging message; and transmitting an RRC connection-resume request message or an RRC connection request message to the eNB based on the indicator.

Abstract: A method for communicating with a network at a user equipment (UE) in a wireless communication system is disclosed. The method includes steps of suspending a connection with the network; selecting one of a first connection procedure or a second connection procedure based on a cause value of a connection provided from a higher layer; and performing the selected connection procedure, wherein the cause value of the connection is determined according to a type of data to be transmitted.

Abstract: Provided are method for a distributed unit (DU) of a base station establishing a bearer in a wireless communication system, and an apparatus for supporting the same. The method may comprise the steps of: receiving a first message including a signaling radio bearer (SRB) identity (ID) from a central unit (CU) of the base station; and establishing a SRB corresponding to the received SRB ID.

Abstract: A method for discarding at least one packet by a user equipment (UE) in a wireless communication system is disclosed. The method includes steps of storing the at least one packet received from an upper layer in a buffer; determining whether or not a number of packets in the buffer is equal to or greater than a threshold value; and discarding the at least one packet from the buffer when the number of packets in the buffer is equal to or greater than the threshold value.

Abstract: An eNodeB (eNB) receives a first paging message including a first user equipment (UE) identity (ID) from a mobility management entity (MME). The eNB checks whether a UE context mapped to the first UE ID is present or not. If it is checked that the UE context mapped to the first UE ID is present, the eNB transmits a second paging message including a second UE ID, which replaces the first UE ID, to a UE.
