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: One disclosure of the present specification provides a method for using packet switching (PS) data off function in user equipment (UE). The method can comprise the steps of: determining whether a session management (SM) delay time timer or a mobility management (MM) delay time timer is being operated, in a state in which the transmission of a non-access stratum (NAS) request message for an SM is required according to a request for the activation or the inactivation of the PS data off function; and, according to the result of the determination, allowing an NAS layer of the UE to include activation or inactivation state information of the PS data off function in the NAS request message for an SM and transmit the same.

Abstract: A method for controlling mobile terminated (MT) data in a wireless communication system and a device therefor are disclosed. The method for controlling MT data by a user equipment (UE) in a wireless communication system includes receiving paging from a network and transmitting a tracking area update (TAU) request message to a mobility management entity (MME) in response to the paging when an EPS update status of the UE is EU2 NOT UPDATED due to an unsuccessful attempt of a last TAU procedure of the UE upon receiving the paging, wherein when the UE is using only signaling optimization to enable delivery of user data over a control plane via the MME, a first active flag in the TAU request message is set.

Abstract: A method for transmitting or receiving a signal of a Session Management Function (SMF) in a wireless communication system comprises receiving a reject message for a message related to an activation command of a Protocol Data Unit (PDU) session, by the SMF, from a User Equipment (UE); requesting, to an AMF, an Access Management Function (AMF) information on a non-3GPP connection state modification of the UE by the SMF; receiving a message indicating that a non-3GPP connection state of the UE has been changed, by the SMF, from the AMF; and transmitting the message related to the activation command of the PDU session, which includes a new P-CSCF(Proxy-Call Session Control Function) list, by the SMF, to the UE, wherein the message indicating that the non-3GPP connection state of the UE has been changed indicates that a non-3GPP access of the UE has been changed from CM-IDLE to CM-connected.

Abstract: Uplink (UL) feedback-based hybrid automatic repeat request (HARQ) retransmission may be proposed as an example for improving downlink (DL) broadcast for vehicle-to-everything (V2X) communication, especially for V2V (vehicle-to-vehicle) communication. An eNodeB (eNB) receives, from a neighboring eNB, an HARQ feedback transmitted by a user equipment (UE), and determines whether an HARQ is to be re-transmitted on the basis of the received HARQ feedback.
