Abstract

　全二重通信方式で通信を行っている２台の通信装置間において、一方の余剰帯域を他方の送信帯域に使用し、交信効率の向上を図る。 　第１の通信装置（Ａ）がデータ送信を行う際に必要となる第１の帯域幅と、第２の通信装置（Ｂ）がデータ送信を行う際に必要となる第２の帯域幅と、を推定する。次に、上記推定した第１の帯域幅と、第１の通信装置（Ａ）が現在使用している第１の使用帯域幅と、を比較すると共に、上記推定した第２の帯域幅と、第２の通信装置（Ｂ）が現在使用している第２の使用帯域幅と、を比較する。そして、第１の帯域幅と、第２の帯域幅と、を調整し、第１の通信装置（Ａ）がデータ送信を行う際に使用する第３の帯域幅と、第２の通信装置（Ｂ）がデータ送信を行う際に使用する第４の帯域幅と、を決定する。
