Abstract

　プレコーディングされた個別パイロット信号のリソース利用効率を高めることができる基地局。互いに異なる巡回遅延を有する複数のパイロットブロックが複数のＵＥにそれぞれ割り当てられる無線通信システムにおいて使用される基地局（１００）において、サイクリックシフト設定部（１１１）が、複数のパイロットブロックにおいて互いに隣接するパイロットブロックの一部が互いにオーバラップするように、複数のパイロットブロック各々の前記遅延時間を設定し、チャネル推定部（１０６）が、ＵＥ毎のパイロットブロックに存在する、各ＵＥによってプレコーディングされた個別パイロット信号から得られるＣＩＲを用いて、各ＵＥのチャネル推定を行う。
