Method and device for co-channel interference coordination

A method and a device for co-channel interference coordination. The method comprises: receiving a co-channel interference coordination request sent by an interfered base station; acquiring interference coordination parameter information of the interfered base station and of a co-channel base station and of an adjacent-channel base station thereof, wherein the frequency spectrum used by said co-channel base station is the same as or overlaps the interfered frequency spectrum, and the frequency spectrum used by said adjacent-channel base station is adjacent to the interfered frequency spectrum; and performing interference coordination for the interfered base station and the co-channel base station according to the interference coordination parameters. The method and device can adjust power of a co-channel base station based on acquired information, thereby reducing co-channel interference between cells.
