Abstract

　移動端末は、Ｌ１／Ｌ２制御情報の候補セット（Candidate Set）をモニターするが、基地局から全ての移動端末に対して候補セットをシグナリングすると、無線リソース的に負荷を重くなる。また、移動端末のブラインド検出を行う処理量も増加する。 　そこで、基地局は、移動端末の属性情報に基づいて、前記Ｌ１／Ｌ２制御信号の送信先となる前記移動端末がグルーピングする処理と、所定の移動端末に送信されるＬ１／Ｌ２制御信号を、所定の移動端末が属するグループに含まれる制御チャネル要素に割り当てて、下り物理制御チャネルを用いて送信する処理とを実行し、移動端末は、下り物理制御チャネルを受信するとともに、移動端末の属するグループに対応した候補セットのブラインド検出処理を行い、候補セットに含まれる制御チャネル要素よりＬ１／Ｌ２制御信号を読み出す処理を実行することとした。
