Abstract: Disclosed is an interference coordination method, a base station, and a high altitude platform station. The high altitude platform station receives information that includes a location of a base station and a radius of a central area of a coverage area of the base station, and calculates an interference start time and an interference end time according to the received information and a flight parameter of the high altitude platform station. The high altitude platform station sends interference coordination information to the base station, where the interference coordination information includes the interference start time, the interference end time, and a frequency band of a carrier used in both an edge area of a coverage area of the high altitude platform station and the central area of the coverage area of the base station. The base station adjusts the coverage area of the carrier according to the interference coordination information.
