Abstract

　システムスループットを向上する無線通信システム、スケジューリング方法、無線基地局装置、及び無線端末装置。無線基地局装置（４００）では、信号分離部（４２０）が、移動端末装置から送信されてくる干渉及び雑音電力の影響が除去された正味の受信電力を示す情報を取得し、干渉／雑音電力測定部（４２５）が、上り回線の干渉及び雑音電力成分を測定し、スケジューラ部（４３０）が、正味の受信電力を示す情報と、上り回線の干渉及び雑音電力成分とに基づいて、上り回線の帯域割り当て及びＭＣＳ選択を行う。これにより、正味の受信電力と上り回線の干渉及び雑音電力成分とで正確な上り回線の通信環境を把握することができ、更に、これらのパラメータに基づいて上り回線の帯域割り当てを行うことができる。この結果、上り回線のスケジューリングを精度良く行うことができるので、システムスループットを向上することができる。
