Abstract: A method and apparatus for obtaining radio access network (RAN) sharing information in a wireless communication system is provided. For an overload procedure, an evolved NodeB (eNB), which is shared by a plurality of operators, receives an indication of overloaded operator from a mobility management entity (MME), and performs an overload action for the overloaded operator indicated by the indication. Further, for a load balancing procedure, a first eNB, which is shared by a plurality of operators, receives a status report per operator from a second eNB, which is shared by the plurality of operators, and performs a load balancing action based on the status report.

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.

Abstract: A method and apparatus for transmitting cell load information in a wireless communication system is provided. A mobility management entity (MME) of an evolved UMTS terrestrial radio access network (E-UTRAN) system receives cell load information of a cell in a universal mobile telecommunications system (UMTS) system, from a radio network controller (RNC) of the UMTS system, and transmits the received cell load information to a plurality of eNodeBs (eNBs) of the E-UTRAN system, respectively.

Abstract: A method and apparatus for forwarding data in a wireless communication system is provided. A small cell receives an indication which indicates stopping serving a small cell service from a macro eNodeB (eNB). Upon receiving the indication, the small cell starts to forward data to the macro eNB together with a sequence number (SN) status transfer message. The indication may be received via a form of a message or a form of an information element (IE) in a message.
