Abstract: Provided are a method for controlling, by a multi-cell coordination entity (MCE), a session for transmitting a V2X message in a wireless communication system, and an apparatus for supporting the same. The method comprises the steps of: receiving, by the MCE, a cell ID and a multimedia broadcast multicast service (MBMS) service area identity (SAI) from a mobility management entity (MME); determining a multicast broadcast single frequency network (MBSFN) area to which the V2X message is to be transferred on the basis of the cell ID; transmitting a session control message to a base station which belongs to the determined MBSFN area, wherein the cell ID may be an ID of a cell to which the V2X message is transmitted.

Abstract: A method and apparatus for receiving a bearer type indication for vehicle-to-everything (V2X) communication in a wireless communication system is provided. An eNodeB (eNB) with roadside unit (RSU) function transmits an indication of local gateway (L-GW) support for V2X communication to a mobility management entity (MME), receives a bearer type indication indicating that a specific bearer is for V2X communication from the MME, and performs an action according to the bearer type indication.

Abstract: Provided are a method for transmitting, by a base station in a wireless communication system, a vehicle to everything (V2X) message, and an apparatus for supporting the same. The base station may receive broadcast area information indicative of areas to which the V2X message will be broadcast, from a multi-cell coordination entity (MCE), receive the V2X message from a terminal, and transmit the received V2X message to a neighboring base station. Provided are a method for transmitting, by a V2X server in a wireless communication system, a vehicle to everything (V2X) message, and an apparatus for supporting the same. The V2X server may receive the V2X message transmitted by a base station from a serving/packet-gateway (S/P-GW), determine a broadcast of the received V2X message, and transmit the V2X message to a base station that belongs to the same multimedia broadcast single frequency network (MBSFN) area as the base station.

Abstract: In an inter-master eNB (MeNB) handover procedure without secondary eNB (SeNB) change, a user equipment (UE) receives a SeNB kept indicator indicating that a SeNB has been kept successfully from a source MeNB. Upon receiving the SeNB kept indicator, the UE determines that the SeNB has been kept successfully in the inter-MeNB handover without SeNB change, and skips the random access procedure to the SeNB.

Abstract: A multi-cell/multicast coordination entity (MCE) determines a cluster to which a vehicle-to-everything (V2X) message. The MCE receives a first session start message, which includes a temporary mobile group identity (TMGI), quality of services (QoS) parameters, and a list of cells, from a V2X application server and determines a cluster, which contains group of cells, to which V2X message is to be broadcast, based on the received TMGI, QoS parameters, and list of cells. Upon determining the cluster, the MCE transmits a second session start message, which includes an indication to notify eNodeB (eNB) to wait for scheduling information, to eNBs corresponding to the determined cluster, and transmits MBMS scheduling information to the eNBs. Further, update of the cluster may be triggered from the V2X application server or from the eNB with limited feedback.

Abstract: A method and apparatus for transmitting location information of a serving small cell in a wireless communication system is provided. A first evolved NodeB (eNB), which may be a master eNB (MeNB) in dual connectivity, receives the location information of the serving small cell served by a second eNB, which may be a secondary eNB (SeNB) in dual connectivity, from the second eNB, and transmits the received location information of the serving small cell to a mobility management entity (MME).

Abstract: As one aspect of mobility enhancement of 3rd generation partnership project (3GPP) long-term evolution (LTE)-wireless local area network (WLAN) aggregation, inter-eNodeB (eNB) handover without WLAN termination (WT) change is considered. A source eNB transmits a handover request message including a WT identifier (ID) and WT XwAP ID to a target eNB. The target eNB transmits a WT addition request message including the WT XwAP ID to a WT, and receives a WT addition request acknowledge message from the WT. The target eNB transmits a handover request acknowledge message indicating that a WT is kept to the source eNB. The source eNB transmits a WT release request message indicating that the WT is kept to the WT. The WT is a logical node that terminates a Xw interface on a WLAN.
