PROBLEM TO BE SOLVED: To allow a plurality of mobile station devices to use the same frequency for transmission at the same time, while suppressing the interference power being given to other cell.SOLUTION: The base station device includes an interference amount index acquisition unit 207 which acquires the index of interference amount that is given from a mobile station unit to other cell to which the mobile station unit does not belong, and allowable duplication number determination units 208-1 through 208-U which set the allowable duplication number of the mobile station unit using the same frequency while duplicating, for the mobile station unit, according to the index of interference amount acquired by the interference amount index acquisition unit 207.
