A communication bit rate computing unit (24) computes the cumulative bit rate of downlink communication data, at which a base station communicates with a terminal, and totalizes the bit rates for each sector area. A amplitude/phase control unit (23) checks whether the cumulative bit rate for each sector area, reported from the communication bit rate computing unit (24), is higher than a first threshold or lower than a second threshold. If the cumulative bit rate is higher than the first threshold, the amplitude/phase control unit (23) performs directing characteristic control so as to narrow the area range of the corresponding sector area to a range smaller than a standard area range. If the cumulative bit rate is lower than the second threshold, the amplitude/phase control unit (23) performs directing characteristic control so as to widen the area range of the corresponding sector area to a range larger than the standard area range.
A radio communication system comprising a base station apparatus having antennas whose directivity can be controlled, and a communication terminal which performs radio communication with said base station apparatus within a service area of said base station apparatus, characterized in that
A base station apparatus characterized by comprising:
A downlink transmission directing characteristic control method for a base station apparatus having antennas whose directivity can be controlled, characterized in that
A program for a downlink transmission, stored on a computer-readable medium, directing characteristic control method for a base station apparatus having antennas whose directivity can be controlled, the program causing a computer to execute a process of calculating a cumulative value of downlink communication bit rates for each of a plurality of sector areas formed by dividing a cell indicating the service area of the base station apparatus, and a process of performing area control so as to make downlink communication bit rates per sector area substantially uniform on the basis of the calculated cumulative values of downlink communication bit rates.
