Abstract: Provided are a method for receiving, by a base station, a user equipment identity (UE ID) in a wireless communication system, and a device for supporting the same. The base station transmits, to a mobility management entity (MME), uplink data and release assistance information transmitted by the UE and receives the UE ID from the MME, wherein the release assistance information can indicate whether transmission of downlink data according to transmission of uplink data is expected.

Abstract: A method and apparatus for handling evolved universal terrestrial radio access network (E-UTRAN) radio access bearer (E-RAB) switch failure for dual connectivity in a wireless communication system is provided. A master evolved NodeB (MeNB) in dual connectivity receives an E-RAB modification confirm message including a list of E-RABs failed to be modified from a mobility management entity (MME). The MeNB may keep old general packet ratio service (GPRS) tunneling protocol (GTP) tunnels for the failed E-RABs, and trigger a secondary eNB (SeNB) release procedure or a SeNB modification procedure for releasing the failed E-RABs. Alternatively, the MeNB may trigger an E-RAB release procedure for releasing the failed E-RABs.

Abstract: A method and an apparatus in which long-term evolution (LTE) and new radio access technology (NR) coordinate/negotiate information on user equipment (UE) capabilities when the LTE and the NR are linked through a dual connection in a wireless communication system. A first radio access network (RAN) node transmits the UE capability already used by the first RAN node and/or the UE capability remaining or recommended to be used by a RAN node 2 to the second RAN node. The second RAN node transmits the UE capability to be used by the second RAN node to the first RAN node on the basis of the received information.

Abstract: A method for transmitting, by a first base station, coverage modification information in a wireless communication system is discussed. The method includes transmitting, by the first base station, the coverage modification information which informs a second base station that modifying a cell managed by the first base station is planned, to the second base station, and after the first base station transmits the coverage modification information to the second base station, modifying, by the first base station, the cell managed by the first base station.

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 for performing a handover procedure in a wireless communication system is provided. A first eNodeB (eNB) of a 3rd generation partnership project (3GPP) long term evolution (LTE) system receives information on an access point (AP) of a wireless local area network (WLAN) system, which is located at neighborhood of a second eNB, to which data of the first eNB can be offloaded, from a user equipment (UE) or a second eNB, and decides whether to handover the UE to the second eNB based on the received information on the AP.

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: Provided are a method for performing paging by a mobility management entity (MME) in a wireless communication system and an apparatus for supporting the same. The MME comprises: receiving an nB from a base station; calculating a paging frame (PF) on the basis of the nB; and transmitting a paging message to the base station on the basis of a paging hyperframe (PH) and the calculated PF, wherein the PH may indicate a number of a hyper system frame in which the paging message is to be transmitted, and the PH may indicate a number of a system frame in which the paging message is to be transmitted.

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.
