Abstract: Disclosed is a method for effectively performing a non-access stratum (NAS) rejection when performing RRC connection resume in a wireless communication system. A method for performing, by a base station, radio resource control (RRC) connection resume in a wireless communication system, includes performing an RRC connection resume procedure with a user equipment (UE), transmitting a resume request message to a mobile management entity (MME), and receiving a resume failure message including an NAS rejection cause from the MME when the resume request has not been permitted.

Abstract: For supporting selection/authorization of network slicing, a radio access network (RAN) node in a new radio access technology (RAT), e.g. gNB, receives a service request including slice information from a user equipment (UE), and determines a slice based on the slice information. The RAN node forwards the service request including the slice information to a common control plane function (C-CPF), and then, the C-CPF checks whether the UE is authorized for a specific slice. The RAN node receives a service response including an authorization indication for the specific slice from the C-CPF, and performs a corresponding action for the specific slice.

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.

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 and apparatus for performing a wireless local area network (WLAN) termination (WT) addition/modification procedure in a wireless communication system is provided. For the WT addition procedure, an eNodeB (eNB) transmits a WT Addition Request message to a WT via a Xw interface, and receives a WT Addition Request Acknowledge message from the WT via the Xw interface. For eNB initiated WT modification procedure, the eNB transmits a WT Modification Request message to a WT via a Xw interface, and receives a WT Modification Request Acknowledge message from the WT via the Xw interface. For the WT initiated WT modification procedure, the eNB receives a WT Modification Required message from a WT via a Xw interface, and transmits a WT Modification Confirm message to the WT via the Xw interface. The WT is a logical node that terminates the Xw interface.

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.
