Abstract

　上り回線の回線品質測定に用いられるパイロット信号を間引くことなく、無線端末装置における消費電力を低減することができる無線通信システム、無線基地局装置、および無線端末装置。上り回線と下り回線とで使用周波数帯域が異なる無線通信システムにおける無線基地局装置（１００）においては、上り回線用パイロット生成部（１１５）が上りＣＱＩ測定用パイロット信号を形成し、上り回線用ＲＦ部（１０５）が上り通信品質測定用パイロット信号を、上り回線パイロット送信区間に上り回線の使用周波数帯域を用いて送信する。こうすることにより、無線基地局装置（１００）が上り回線の回線品質測定に用いる、上り通信品質測定用パイロット信号を上り回線の周波数帯域を用いて送信するので、無線端末装置における消費電力を削減することができる。
