Abstract

　ユーザ端末から基地局にチャネル品質情報を報告するチャネル品質情報報告方法は、基地局が、ユーザ端末の情報に基づいてチャネル品質情報フォーマットを決定するフォーマット決定ステップ；基地局が、決定されたチャネル品質情報フォーマットをユーザ端末に送信するフォーマット送信ステップ；ユーザ端末が、受信した前記チャネル品質情報フォーマットに基づいてチャネル品質情報を生成するチャネル品質情報生成ステップ；を有する。基地局は、所要のデータレートに基づいてチャネル品質情報フォーマットを決定してもよい。また、基地局は、遅延スプレッドに基づいてチャネル品質情報フォーマットを決定してもよい。また、基地局は、移動速度に基づいてチャネル品質情報フォーマットを決定してもよい。
