PROBLEM TO BE SOLVED: To lower channel correlation in radio stations which are spatial multiplex communication objects regardless of the antenna configuration of a base station device.SOLUTION: A base station device comprises: a channel information acquisition unit that, before scheduling processing, acquires channel information, per frequency component, on each of paths between a plurality of antenna elements and radio stations, and has a channel information storage unit store it; and an allocation radio station determination unit that, as scheduling processing, selects one radio station as a determination object radio station from radio stations waiting for allocation of a communication opportunity, and allocates the determination object radio station a communication opportunity if an evaluation value calculated on the basis of a correlation value of channel information on each frequency component between each of radio stations to which a communication opportunity is already allocated and the determination object radio station is less than a predetermined first threshold value, and/or if all accumulation values obtained by calculating accumulation values of evaluation values with other radio stations per radio station at the radio stations to which a communication opportunity is already allocated and the determination object radio station is less than a predetermined second threshold value. |
