A base station requiring interference coordination among the interfering cell base stations is determined according to the interference levels and power coordination information of the interfering cell base stations. A power adjustment request is sent to the base station requiring interference coordination so that the base station requiring interference coordination adjusts a transmit power on the specific channel resource.
