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.

Abstract: A method and apparatus for supporting a fast link recovery and link status reporting in a wireless communication system is provided. When a node detects a radio link problem on a wireless backhaul link between integrated access and backhaul (IAB) nodes from the node to a donor node of an TAB network, the node reselects a cell operated by a gNB which is directly connected to the donor node, and performs a random access procedure towards the cell operated by the gNB to report information on the radio link problem to the cell. The donor node may establish a new path for the node.

Abstract: Disclosed are a method for processing a NAS message in a wireless communication system and an apparatus for the same. Specifically, a method for processing a non-access stratum (NAS) message by an access and mobility management function (AMF) in a wireless communication system may include: receiving, from a user equipment (UE), an uplink (UL) NAS transport message including an uplink message; and when the uplink message is not successfully transported to a network function (NF), transmitting, to the UE, a first downlink (DL) NAS transport message indicating that the uplink message is not transported.

Abstract: Disclosed are a method for performing V2X communication in a wireless communication system and an apparatus therefor. Specifically, a method for supporting, by a base station, a user equipment (UE) to perform vehicle-to-everything (V2X) communication with a vehicle through a PC5 interface in a wireless communication system may include: receiving a sidelink UE information message for requesting resource allocation for the V2X communication through the PC5 interface from a UE in a limited service state; checking whether the UE has a capability to use the V2X communication with an emergency packet data network (PDN) connection or whether the UE is authorized to perform the V2X communication; and allocating a resource for the V2X communication when the UE has the capability to use the V2X communication with the emergency (PDN) connection or the UE is authorized to perform the V2X communication.

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: A method and a device for determining an evolved packet system (EPS) mobility management (EMM) mode in a wireless communication system are disclosed. More specifically, a method for determining, by a user equipment (UE), an EMM mode in a wireless communication system includes receiving, by the UE in an EMM-IDLE mode with suspend indication, from a base station a system information block (SIB) including information that a serving cell of the UE does not support user plane (UP) cellular Internet of Things (CIoT) EPS optimization; storing the information that the serving cell does not support the UP CIoT EPS optimization; and maintaining the EMM-IDLE mode with suspend indication if a procedure using an initial non-access stratum (NAS) message is not triggered and the serving cell is changed to a cell supporting the UP CIoT EPS optimization.

Abstract: Disclosed are a method and an apparatus for suspending/resuming NAS signaling in a wireless communication system. Specifically, a method for a user equipment (UE) to suspend/resume non-access stratum (NAS) signaling connection in a wireless communication system comprises: a step in which when a NAS layer of the UE receives, from a radio resource control (RRC) layer, an indication that RRC connection is suspended, the UE enters an evolved packet system (EPS) mobility management (EMM)-idle mode involving a suspension indication; and a step in which when a procedure using a first NAS message is triggered, the RRC layer of the UE is requested to resume the RRC connection, wherein the request comprises a cause of RC establishment and a call type, and when the UE is in a narrow band (NB)-S1 mode, the request may further comprise data volume information of the first NAS message.

Abstract: Provided is a method for a wireless device for transmitting an RRC message according to one disclosure of the present specification. The method may comprise a step for an NAS stratum of the wireless device transmitting an NAS signaling request message to an AS layer to transmit the former to a network node. The NAS signaling request message can comprise therein an indication of one or both preferred or required plans from among the plans for optimizing the EPS for CIoT using a control plane (CP) or a user plane (UP). The method may comprise a step for the NAS stratum of the wireless device receiving, from the AS stratum, an NAS signaling acceptance message or NAS signaling rejection message from the network node.
