Abstract

【課題】　周辺セル間で相互に与え合う干渉を低減し、トータルスループットを最大限維持しながらデータ伝送を行う。 【解決手段】　通信相手先から受信した信号から、当該通信相手先が周辺セルから受けている干渉電力量情報を取得する取得部（１０５）と、前記干渉電力量情報に応じてデータ伝送に使用するサブキャリアの本数を判定する判定部（１０６）と、前記干渉電力量情報に応じてデータ伝送に使用するサブキャリア毎の変調方式を決定する変調方式決定部（１０７）と、を備え、前記判定部（１０６）で判定された本数のサブキャリアを使用して前記変調方式決定部（１０７）により決定された変調方式により無線信号を前記通信相手先に送信する。
