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 and apparatus for transmitting a local home network identity (LHN ID) in a wireless communication system is provided. A first evolved NodeB (eNB) transmits an X2 Setup Request message including a LHN ID of the first eNB to a second eNB, and receives an X2 Setup Response message including a LHN ID of the second eNB from the second eNB. The first eNB may determine whether or not to trigger a secondary eNB (SeNB) addition procedure according to the LHN ID of the second eNB. When it is determined that the LHN ID of the second eNB is the same as the LHN ID of the first eNB, the first eNB may trigger the SeNB addition procedure.

Abstract: The present invention relates to a method and a device for performing cell shaping. A base station can establish a cell shaping plan on the basis of current states. The current states may be the load of the base station and the traffic space distribution of the base station. The base station transmits a first message to a neighboring base station and receives a second message from the neighboring base station in response to the first message. The first message may include the cell shaping plan, and the second message may include whether or not the neighboring base station can perform cell shaping. The base station can determine whether or not to perform cell shaping on the basis of the second message.

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 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.
