Method and device for coordinating co-channel interference

The invention relates to a method and device for coordinating co-channel interference. The method includes: receiving a co-channel interference coordinating request sent by an interfered base station; obtaining interference coordinating parameter information of the interfered base station and a co-channel base station and an adjacent channel base station of the interfered base station, wherein a frequency spectrum used by the co-channel base station of the interfered base station is the same as or overlapped with an interfered frequency spectrum, and a frequency spectrum used by the adjacent channel base station of the interfered base station is adjacent to the interfered frequency spectrum; and interference coordinating is conducted for the interfered base station and the co-channel base station of the interfered base station according to interference coordinating parameters. By means of the method and device, co-channel interference among cells can be reduced effectively.
