Abstract

　複数の受信装置宛ての送信信号を複数のアンテナを用いて多重送信する場合に、各受信装置へのウェイトベクトルの割り当てを決定する処理負担を軽減する。 　送信装置（１０）は、受信装置（２０，３０，４０）宛ての送信信号をウェイトベクトルに応じて多重化して、アンテナ（１１ａ，１１ｂ，１１ｃ）を用いて無線送信する。ここで、送信装置（１０）の制御部（１２）は、まず第１の受信装置を選択してウェイトベクトルを割り当てる。次に、第１の受信装置に割り当てたウェイトベクトルと並列して使用可能なウェイトベクトルの候補の情報を第２の受信装置宛てに出力する。そして、第２の受信装置からのフィードバック情報に基づいて第２の受信装置にウェイトベクトルを割り当てる。
