Abstract

　セル間干渉が改善されるまでの時間を短縮してシステムスループットを向上する送信制御方法、無線通信システム及び無線基地局装置。基地局（２００）では、ＦＦＴ部（２１０）が、それぞれ異なる隣接セルに存在する複数の無線端末（１００）から隣接セルの間で共通する共通無線リソースを用いて送信された干渉レポートを受信し、アダプティブＦＦＲ処理部（２３０）が、受信干渉レポートに基づいて、自セルの下り回線におけるアダプティブＦＦＲ処理を制御する。こうして隣接セルに存在する無線端末（１００）から直接的に干渉レポートの報告を受けて、隣接セルの干渉状況を考慮した上で送信モードの変更を行うことができる。このため、従来、隣接する基地局（２００）の間で行われていた送信モード変更の報告を行う必要がない。その結果、システムで必要なシグナリングが削減され、システムスループットを向上できる。
