Abstract

　基地局装置が管理するセル内にあるすべての移動局装置あるいはマルチキャストサービス受信中のすべての移動局装置に対して、移動局装置が受信品質情報を送信する際に使用する受信品質管理情報を効率的に指定する。移動局装置２００が選択した受信品質情報を基地局装置１００に送信し、基地局装置１００が移動局装置２００から受信した受信品質情報に基づいてリソースの割り当てを行なう移動通信システムにおいて、基地局装置１００は、制御しているセル内の移動局装置２００が受信品質情報を送信する際に使用する受信品質管理情報を報知信号等に含めて送信し、移動局装置２００は、報知信号等を受信した場合、受信品質管理情報の内容に応じて受信品質情報を基地局装置１００に送信する。
