Abstract

　基地局装置が移動局装置にランダムアクセスを実行させる必要があると判断した場合に、未使用のシグネチャがあるかを判定する。そして、シグネチャを移動局装置が利用することができる有効期間を決定し、当該有効期間の終了時間を算出する。そして、シグネチャと算出された終了時間とをランダムアクセスプリアンブル割当てメッセージに含めて移動局装置に送信する。移動局装置は、ランダムアクセスプリアンブル割当てメッセージから、シグネチャと終了時間とを抽出し、抽出された終了時間に基づいて、シグネチャを含んだランダムアクセスプリアンブルを送信可能なランダムアクセスチャネルを決定する。これにより、基地局装置と移動局装置との間において、シグネチャの有効期間内であっても、他の移動局装置にシグネチャを割り当てることにより効率よく通信を行うことができる基地局装置等を提供することができる。
