Abstract: Provided are a method for performing, by a multi-cell coordination entity (MCE), a vehicle-to-everything (V2X) communication in a wireless communication system, and an apparatus for supporting the same. The method comprises the steps of: receiving, from an MME, information on a cell group and an indication which instructs the MCE to perform either of a multicast broadcast single frequency network (MBSFN) operation or a single-cell point-to-multipoint (SCPTM) operation; determining to perform either of the MBSFN operation or the SCPTM operation on the basis of the indication; and transmitting, to a base station, the information on the cell group received from the MME, on the basis of the information on the cell group and the determined operation, wherein the information on the cell group may be information related to a cell group to which a V2X message is to be delivered, and the base station may be a base station that manages cells which belong to the cell group to which the V2X message is to be delivered.

Abstract: When a user equipment (UE) requests a service simultaneously during a mobility management (MM) attach procedure in a new radio access technology (NR; or new RAT) system, slice related information may be transmitted together. In detail, a radio access network (RAN) node receives a network connection request, a service request and slice related information from the UE, and routes the network connection request, the service request to a dedicate common control plane function (C-CPF) according to the slice related information.

Abstract: A method and apparatus for performing an inter-master eNodeB (MeNB) handover procedure without secondary eNB (SeNB) change in a wireless communication system is provided. A source MeNB transmits a handover request message including a first indication of a SeNB to a target MeNB. The first indication may correspond to a SeNB identifier (ID). Upon receiving the handover request message including the first indication, the target MeNB transmits a SeNB addition request message including a second indication of a UE, served by the SeNB, to the SeNB. The second indication may correspond to an old SeNB UE X2AP ID, which was allocated by the SeNB. Upon receiving the SeNB addition request message including the second indication, the SeNB may transmit a SeNB addition acknowledge message including a third indication of keeping bearers of the SeNB from the SeNB.
