Disclosed is a carrier wave allotting method of an operation and maintenance system in a wireless communication network. The carrier wave allotting method includes searching a wireless resource of the wireless communication network; updating cell information indicating information of cells of the wireless communication network; searching an access mode of a station connected with the operation and maintenance system; searching a wireless capacity of the station; and allotting a carrier wave to the station according to the wireless resource, the cell information, the access mode, and the wireless capacity.

The present invention provides a method including two operations of a first operation and a second operation. The first operation may determine between a terminal located in a space including the small base station and a terminal located in a space excluding the small base station based on a value reported by a terminal. The second operation may be performed using information received from a neighboring macro base station in response to the determination failing to be performed in the first operation, thereby ultimately discriminating between an area including the small base station and an area excluding the small base station corresponding to a location of a terminal.

摘要:
A method and an apparatus for controlling transmission power in a femto base station is provided. The method includes: predicting femto base station interference to be given from an adjacent femto base station to a terminal; predicting macro base station interference to be given from a macro base station to the terminal; determining transmission power for the terminal; and transmitting a downlink signal to the terminal on the basis of the transmission power, wherein the femto base station interference is predicted on the basis of a distance between serving femto base station and the adjacent femto base station and the transmission power of the adjacent femto base station, and the macro base station interference is predicted on the basis of a distance between serving femto base station and the macro base station and the transmission power of the macro base station.
摘要:
A method of operating a closed-mode base station, includes broadcasting an interference preamble for providing a notification of an interference situation via a broadcast of system information; checking current service status of the closed-mode base station when the interference situation is reported from a non-subscriber terminal entered a service area of the closed-mode base station; and avoiding the interference situation based on the checked current service status.

Disclosed is a method of operating a femto base station (BS) in a wireless communication system, the method comprising: receiving an access request comprising a closed subscriber group (CSG) identifier (ID) from user equipment (UE); determining a number N of UE accessing the femto BS; ascertaining an access type to determine whether the UE is a CSG UE or a non-CSG UE of the femto BS on the basis of the CSG ID of the UE; and determining whether to admit access of the UE on the basis of the access type, the N and access admittable information, the access admittable information comprising UCSG, i.e., a maximum number of CSG UE of which access is admitted; UALL, i.e., a maximum number of non-CSG UE of which access is admitted; and UMAX, i.e., a maximum number of UE of which access is admitted.
摘要:
Provided are a mobile communication system comprising a femto base station for transmitting system information, and a terminal for receiving the system information from the femto base station. The terminal receives the system information from the femto base station, and during other times, receives data from a serving macro base station.
摘要:
Provided is a method of managing mobility of a user equipment. The method includes: establishing by a first base station a communication with the user equipment; transmitting by the first base station a Coordinated Multiple Point (CoMP) addition request to a second base station; establishing by the first and second base stations a CoMP communication with the user equipment according to the CoMP addition request; transmitting by the first base station an anchor cell change request to the second base station; and operating the second base station as an anchor cell of the CoMP communication according to the anchor cell switch request.
