Abstract: A method for transmitting a protocol data unit (PDU) by a user equipment (UE) via a device to device (D2D) link at a relay user equipment (UE) in a wireless communication system is disclosed. The method includes steps of receiving the PDU from a remote UE via the D2D link; identifying a priority of a service data unit (SDU) from a payload included in the PDU; allocating the SDU to a bearer corresponding to the priority; and transmitting the SDU via the allocated bearer to a network.

Abstract: Provides are a method for performing, by a terminal in a WLAN interworking operation, handover in a wireless communication system and an apparatus supporting the same. The terminal may be instructed to perform handover from a source cell to a target cell, but may receive a handover command including a WLAN interworking configuration indication to indicate that the terminal maintains or releases a WLAN interworking configuration for a WLAN being accessed by the terminal. The terminal may attempt to perform the handover to the target cell in the state in which the terminal has maintained the WLAN interworking configuration if the WLAN interworking configuration indication indicates that the terminal maintains the WLAN interworking configuration.

Abstract: Provided is a method for communicating performed by a terminal in a wireless communication system. The method comprises receiving from a first access network a second access network search configuration for searching a second access network, and receiving traffic routing criteria from the first access network. The traffic routing configuration specifies traffic routing criteria for processing traffic of the first access network by routing to a second access network, determining a mobility state of the terminal, searching the second access network based on the second access network search configuration, evaluating whether a second access network entity discovered through the search satisfies the traffic routing criteria, and processing the traffic of the first access network through the second access network entity. The second access network searching and/or the traffic routing criteria satisfaction evaluating is performed based on the mobility state of the terminal that is determined.
