Abstract

　干渉波ピークが自セルに割り当てられた巡回シフト系列の検出窓に入ることを防止し、基地局におけるチャネル推定精度を向上させる無線通信端末装置、無線通信基地局装置及び無線通信方法を開示する。フレーム同期が確立した全てのセル及び各端末の送信帯域幅に対して基準となる周波数を設定し、この周波数を基準点として、参照信号生成部（１０８）の位相回転付加部（１１０）は、基準点と参照信号の送信帯域の周波数差δに相当する位相回転を周波数領域において参照信号となるZC系列に付加する。位相回転が付加されたZC系列は、多重化部（１１４）において送信データと多重され、多重信号が送信ＲＦ部（１１５）から送信される。
