Abstract: A method and apparatus for prioritizing one of a multimedia broadcast multicast service (MBMS) reception or a device-to-device (D2D) reception in a wireless communication system is provided. A user equipment (UE) prioritizes one of the MBMS reception or the D2D reception if the UE cannot support both MBMS reception and the D2D reception simultaneously, and indicates a result of the prioritization to the network. The result of the prioritization indicates either that the MBMS reception is prioritized over the D2D reception or the D2D reception is prioritized over the MBMS reception.

Abstract: A method and apparatus for performing a random access (RA) procedure in a wireless communication system is provided. A user equipment (UE) establishes connection with a first node and a second node, and transmits an RA preamble to the second node. If a number of RA preamble transmissions reaches a maximum number, the UE stops uplink (UL) transmission of all cells in a group to which the second node belongs, and transmits an indication indicating that transmission of the RA preamble has failed to the first node.

Abstract: During path switching between sidelink (SL) and uplink (UL) for vehicle-to-everything (V2X) message transmission, a path switching layer of a user equipment (UE), which may be located right above a packet data convergence protocol (PDCP) layer of the UE, stores a vehicle-to-everything (V2X) message, which is not transmitted yet on an old path, in a transmission buffer. And then, the path switching layer of the UE re-submits the V2X message stored in the transmission buffer to a lower layer of a new path.

Abstract: A method and apparatus for performing access control for wireless local area network (WLAN) interworking in a wireless communication system is provided. A user equipment (UE) receives access class barring information for a traffic steered from a WLAN to 3rd generation partnership project (3GPP) long-term evolution (LTE) from a network, and performs access barring check for the traffic steered from the WLAN to the 3GPP LTE using the received access class barring information. If a cell is not barred according to the access barring check, the UE transmits a radio resource control (RRC) connection request message to the network.
