Abstract

複数の移動局と，前記複数の移動局と無線により通信を行う基地局を備え，複数の移動局からのデータ信号が，周波数方向に複数のチャネルで多重化されてタイムスロットを形成し，更にタイムスロットが時分割多重されて送信され，基地局は，移動局側から送られたタイムスロット毎に周波数分割多重化されたデータ信号を分離して受信し，データ信号の受信が不良であるとき，対応する移動局に再送を要求する移動通信システムである。所定の時間間隔毎のタイムスロットに無線リンク接続のために送信されるランダムアクセスチャネルが多重化され，ランダムアクセスチャネルが多重化されるタイムスロットには，再送不要データ信号のみを周波数多重化し，複数の移動局は，基地局から再送要求のある時，ランダムアクセスチャネルが多重化されるタイムスロット以外のタイムスロットに前記再送要求されたデータ信号を周波数多重して基地局に再送する。
