RADIO COMMUNICATION DEVICE, RADIO COMMUNICATION METHOD AND COMPUTER PROGRAM

PROBLEM TO BE SOLVED: To prevent the occurrence of a communication collision between Wi-Fi communication and non-Wi-Fi communication, when the Wi-Fi communication and the non-Wi-Fi communication use an identical frequency band in an identical area.SOLUTION: A radio communication device includes: a radio receiver unit 11 which receives, when a plurality of radio channels are simultaneously used, each signal of the plurality of radio channels having an identical format and an identical modulation rate and simultaneously transmitted through the plurality of radio channels; a radio transmitter unit 12 which transmits a signal through at least one radio channel among the plurality of radio channels; a detector unit 13 which detects the simultaneous reception of the plurality of radio channels in the radio receiver unit 11; a determination unit 14 which determines a coincidence condition between signals simultaneously received by the plurality of radio channels and detected by the detection unit 13; and a control unit 15 which, when the determination unit 14 determines that the coincidence condition is satisfied, delays signal transmission from the radio transmitter unit 12 as long as a predetermined transmission waiting time.SELECTED DRAWING: Figure 1 【課題】同一地域でＷｉ−Ｆｉ通信と非Ｗｉ−Ｆｉ通信とが同一周波数帯を使用する場合に、Ｗｉ−Ｆｉ通信と非Ｗｉ−Ｆｉ通信との間で通信の衝突が発生することを防ぐこと。【解決手段】複数の無線チャネルが同時に使用される際に同一フォーマットの信号が同一変調レートで該複数の無線チャネルで同時に送信される該複数の無線チャネルの各々の信号を受信する無線受信部１１と、該複数の無線チャネルのうち少なくとも一つの無線チャネルで信号を送信する無線送信部１２と、無線受信部１１における複数の無線チャネルの同時受信を検出する検出部１３と、検出部１３で検出された同時受信の複数の無線チャネルで各々受信された信号についての一致条件を判定する判定部１４と、判定部１４で一致条件を満足すると判定された場合に、無線送信部１２からの信号の送信を所定の送信待ち時間だけ遅らせる制御部１５と、を備える。【選択図】図１
