摘要： PROBLEM TO BE SOLVED: To provide a radio communication method of frequency reuse with high flexibility by sharing a frequency band with multiple adjacent base stations.SOLUTION: A radio communication system comprises a plurality of base stations and a plurality of terminal stations. The radio communication system considers respective base stations which lie next to each other as first adjacent base stations mutually, and respective base stations between two of which another base station exists as second adjacent base stations mutually. Each base station sets a first adjacent priority band where its own base station can preferentially use among the first adjacent base stations, and sets a second adjacent priority band where its own base station can preferentially use among the second adjacent base stations in a part of the first adjacent priority band of each base station. When a base station communicates with a terminal station under the base station, the base station notifies each other of a transmission stop request and a transmission power reduction request by identifying a first adjacent base station and a second adjacent base station which interfere with communication of the base station in the case that the first adjacent base station and the second adjacent base station of the base station use the same frequency at the same time as the communication of the base station.
