Abstract: Provided are a method in which a source base station (BS) transmits a Quality of Service (QoS) flow-to-data radio bearer (DRB) mapping rule to a target BS in a wireless communication system, and a device supporting the same. The method may include: receiving, from a user equipment (UE), a measurement result of a target cell; determining the handover of the UE to the target BS on the basis of the measurement result; and transmitting, to the target BS, a handover request message including a QoS flow-to-DRB mapping rule of the source BS.

Abstract: A method and apparatus for performing access control and/or membership verification for dual connectivity in a wireless communication system is provided. A first evolved NodeB (eNB) transmits a closed subscriber group (CSG) membership status of a user equipment (UE) to a second eNB, which is a home eNB (HeNB), and receives at least one of a CSG identifier (ID) or a cell access mode of the second eNB from the second eNB. A mobility management entity (MME) may verify the CSG membership status of the UE and transmit the verified CSG membership status of the UE to the first eNB. And then, the first eNB transmits the verified CSG membership status of the UE to the second eNB.

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: The present invention relates to a method and an apparatus for transmitting information among base stations for inter-cell interference cancellation in a massive MIMO or FD-MIMO system. A base station acquires interference area information, which is information on an area causing interference to a neighbor base station, and transmits the interference area information to the neighbor base station. The interference area information may include any one from among the vertical and horizontal angles of a beam causing interference to the neighbor base station, or the number of the area causing interference to the neighbor base station.

Abstract: A method and apparatus for performing a transport network layer (TNL) address discovery procedure in a wireless communication system is provided. A first eNodeB (eNB) transmits at least one of a TNL address of the first eNB and a TNL address of an X2-gateway (GW), and a source eNB identifier (ID). The eNB may further transmit an indication of X2 setup which indicates whether a direct X2 interface between the first eNB and a second eNB or an indirect X2 interface going through the X2-GW is to be set up.

Abstract: A method and apparatus for deciding a secondary eNB (SeNB) user equipment aggregate maximum bit rate (UE-AMBR) in a wireless communication system is provided. In one embodiment, a master evolved NodeB (MeNB) in dual connectivity receives assistant information, which includes at least one of a buffer size or load information of a SeNB, from the SeNB, and decides whether to change a SeNB UE-AMBR based on the assistant information. In another embodiment, the MeNB transmits an indication which requests change of a SeNB UE-AMBR to a SeNB, receives information related to a new SeNB UE-AMBR from the SeNB; and decides whether to change the SeNB UE-AMBR based on the information related to the new SeNB UE-AMBR.
