Abstract

　複数のシステム帯域幅を設けた通信システムにおいて、ＣＱＩ（Channel Quality Indicator）測定のための処理量を低減できる受信装置。この装置において、狭帯域ＣＱＩ測定部（１０９）は、送信装置から送信される狭帯域幅の開始位置から、ＣＱＩ測定用数分のリソースブロックにおけるＣＱＩを狭帯域ＣＱＩとして測定し、広帯域ＣＱＩ測定部（１１０）は、送信装置から送信されるシステム帯域幅の中から、ＣＱＩ測定用数分のリソースブロックを抽出し、抽出されたリソースブロックにおける平均ＣＱＩをシステム帯域幅全般のチャネル品質を表す広帯域ＣＱＩとして測定し、フィードバック情報生成部（１１１）は、狭帯域ＣＱＩと、広帯域ＣＱＩとを含むフィードバック情報を生成する。
