Abstract: A base station device performs switching of its transmission power distribution in accordance with a transmission power distribution switching timing of another base station device. The base station device includes a control unit 22 that controls transmission power distribution in the frequency domain, and a detection unit 23 that detects a switching timing at which another base station device switches transmission power distribution. The control unit 22 changes its transmission power distribution at a power distribution switching timing in the another base station device or a timing near the switching timing. Accordingly, inter-cell interference is prevented.
