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 transmitting an indication for coordination of 3rd generation partnership project long-term evolution (3GPP LTE) and wireless local area network (WLAN) in a wireless communication system is provided. In a cell-specific scheme, an eNodeB (eNB) transmits a first indication of WLAN offloading support to a mobility management entity (MME), and receives a second indication of applying different charging rules from the eNB. Alternatively, in a user equipment (UE)-specific scheme, the eNB transmits a first indication of WLAN offloading support to the MME, receives a second indication of which bearer can be offloaded or not from the eNB, and applies offloading for a specific UE according to the second indication.

Abstract: A method and apparatus for transmitting a cell shaping/un-shaping indication in a wireless communication system is provided. A first eNodeB (eNB) transmits a cell shaping/un-shaping indication which indicates cell shaping/un-shaping of a cell, managed by the first eNB, in an active antenna system (AAS) to a second eNB. The cell shaping means that main coverage of the cell is maintained unchanged but an edge of the cell can be adapted to load demand. The cell un-shaping means that coverage of the cell goes back to original coverage.
