Abstract

　移動局から基地局へ、基地局で通信の制御処理を行うための限られた複数の特定パターンを有する制御信号（ＡＣＫ信号／ＮＡＣＫ信号など）を送り、基地局は、この制御信号を用いて上りＳＩＮＲ測定を行う。また、このような制御信号を用いてＳＩＮＲを測定する手法と、従来同様のＳＩＮＲ測定用の専用信号を用いてＳＩＮＲを測定する手法を、制御信号の有無によって切り替える。さらに、上りＳＩＮＲの測定結果に基づいて上りリンクのスケジューリングを行う。このスケジューリングにおいて、サブキャリアが分散して配置された制御信号を用いて、周波数ブロックごとにＳＩＮＲを測定し、周波数スケジューリングを行うようにしてもよい。
