Abstract

　ＳＣＣＨ（Shared Control Channel）等の制御チャネルによる通信オーバーヘッドを低減することができる無線通信基地局装置。この装置において、各符号化部１１は、移動局毎のＳＣＣＨに対して符号化処理を行い、各変調部１２は、符号化後のＳＣＣＨに対して変調処理を行い、配置部１０２は、各移動局へのＳＣＣＨを、ＯＦＤＭシンボルを構成する複数のサブキャリアのいずれかに配置し、送信電力制御部１０３は、各移動局から報告された受信品質情報に基づいてＳＣＣＨの送信電力を制御する。ＭＣＳ設定部１２０は、ＳＣＣＨの多重数に応じて符号化・変調部１０１－１～１０１－ｎにおけるＭＣＳを設定する。
