Abstract

　ＤＬ帯域幅とＵＬ帯域幅とが異なるＴＤＤ方式の無線通信システムにおいて、ＤＬ－ＣＳＩのフィードバック量を削減することができる基地局装置。この装置において、逆多重化部１３３は、通信相手の複数のＵＥからフィードバックされるＵＬパイロット、ＤＬ－ＣＱＩおよびＤＬ－ＣＳＩを分離し、チャネル推定部１３４は、一部帯域を重畳してＤＬチャネルとＵＬチャネルとを割り当てられたＵＥからのＵＬパイロットを用いてチャネルサウンディングを行ってＵＬ－ＣＳＩを得、制御用ＤＬ－ＣＳＩ取得部１３５は、上記ＵＥからフィードバックされる、ＤＬチャネルとＵＬチャネルとの重畳しない帯域に含まれる一部のＲＢのＤＬ－ＣＳＩを用いて、ＤＬ－ＣＳＩの補間を行い、ＤＬ閉ループ制御部１０４は、推定されたＵＬ－ＣＳＩと、補完されたＤＬ－ＣＳＩとを合わせてＤＬ閉ループ制御用のＤＬ－ＣＳＩとして用いる。
