PROBLEM TO BE SOLVED: To provide a radio communication apparatus capable of improving the throughput in a system carrying out Full Duplex communication.SOLUTION: A radio communication apparatus in an embodiment includes: a reception part configured to receive a first frame transmitted from a first radio communication apparatus using a predetermined frequency bandwidth; and a control unit configured to carry out propagation path estimation based on the first frame to acquire a piece of propagation path information between own device and the first radio communication apparatus. The reception part is configured to receive a second frame transmitted by a second radio communication apparatus. The control unit is configured to calculate a weight factor for each of plural antennas for suppressing reception of signal transmitted from the first radio communication apparatus using the propagation path information. The reception part is configured to receive a third frame which is transmitted from the second radio communication apparatus using the weight factor after a predetermined time from transmission of the second frame using the predetermined frequency bandwidth.SELECTED DRAWING: Figure 1 【課題】Ｆｕｌｌ Ｄｕｐｌｅｘ通信を行うシステムにおけるスループットの改善を図る。【解決手段】本発明の実施形態としての無線通信装置は、所定の周波数帯域で第１無線通信装置が送信する第１フレームを受信する受信部と、前記第１フレームに基づき伝搬路推定を行うことにより、前記第１無線通信装置と自装置間の伝搬路情報を取得する制御部と、を備え、前記受信部は、第２無線通信装置が送信する第２フレームを受信し、前記制御部は、前記伝搬路情報を用いて、前記第１無線通信装置からの信号の受信を抑制するための複数のアンテナ毎のウェイト係数を算出し、前記受信部は、前記第２フレームの送信から予め定めた時間後に前記第２無線通信装置から前記所定の周波数帯域で送信される第３フレームを、前記ウェイト係数を用いて受信する。【選択図】図１
