MULTI-CARRIER WIRELESS COMMUNICATION SYSTEM, CONTROL STATION, BASE STATION, AND MULTI-CARRIER WIRELESS COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To communicate without producing interference in communication areas of respective base stations in an overlap area even if the operational patterns of frequency bands in neighboring respective base stations are distinct from one another. SOLUTION: This multi-carrier wireless communication system: informs intelligence on splitting patterns of the frequency bands in the respective base stations to a control station; sets a part of a utilization possible subcarrier contained for every base station in at least one splitting bandwidth as an exclusive subcarrier; distributes an exclusive subcarrier intelligence which shows exclusive subcarrier set to each the base station to each the base station and radio communication terminal in a communication area; judges whether radio communication terminal set as a transmission object of the base station is in an interference area, or in a non-interfering area; performs a transmission with the radio communication terminal with exclusive subcarrier established to the base station when it exists in the interference area; and performs transmission with the radio communication terminal with exclusive subcarrier contained in at least one splitting bandwidth when it exists in the non-interfering area.
