Abstract: When a non-access stratum (NAS) message is generated in an NAS layer of a user equipment, the NAS layer transfers the NAS message and type information to an access stratum (AS) layer of the user equipment. An AS message containing the NAS message is transmitted to a network. The type information indicates whether the NAS message is a first type message containing user data or a second type message without user data.

Abstract: User data may be transmitted through a signaling radio bearer (SRB) by using an NAS message. A new SRB different from the existing SRB0, SRB1, and SRB2 may be defined for transmission of the user data. The new SRB may be used to deliver the NAS message containing the user data before security is activated.

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 me3ssage 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: Disclosed herein are a method and apparatus for monitoring UE reachability in a wireless communication system. A method for monitoring UE reachability may include receiving, by a Mobility Management Entity, a monitoring request message for UE reachability including a maximum response time from a Home Subscriber Server, detecting, by the MME, the UE reachability if it is expected that paging is able to be transmitted to UE when extended Discontinuous Reception is applied to the UE, and sending, by the MME, a UE reachability notification to a Service Capability Exposure Function before a next paging occasion of the UE, wherein the maximum response time may indicate a time during which the UE maintains a reachable state so that downlink data is reliably delivered to the UE, and wherein an occasion when the UE reachability notification is transmitted may be determined by taking into consideration the maximum response time.

Abstract: Disclosed are a method for cell granularity reporting in a wireless communication system and a device therefor. The method for performing cell granularity reporting by a user equipment (UE) in an idle state in a wireless communication system includes receiving a cell granularity reporting configuration from a network, detecting whether a cell in which the UE is camping in the idle state is changed, and when it is detected that the cell in which the UE is camping is changed, transmitting cell change information to the network, wherein the cell granularity reporting configuration includes an indication regarding whether to receive a multimedia broadcast and multicast service (MBMS), and when the indication regarding whether an MBMS is received is activated, the UE does not perform the cell granularity reporting unless the UE receives MBMS data.
