Provided is a base station device capable of improving the frequency-utilization efficiency while maintaining the communication quality. The base station device includes a plurality of directional antennas, power control means controlling transmission power and frequency management means managing frequency bands and forms a cell. The cell is formed with layers of a base cell having a cell border with a cell formed by a neighboring base station device and including a plurality of sector cells and a small-cell having a cell radius smaller than a cell radius of the base cell and including at least four sector cells by the plurality of directional antennas and the power control means. The frequency management means manages frequency bands so that frequency bands different from each other are allocated to the sector cells of the base cell, and a frequency band, which is different from the frequency bands allocated to the base cell and different between neighboring sector cells but the same between at least two sector cells, is allocated to each of the sector cells of the small-cell. |
