Abstract

共通パイロット信号を送信する無線基地局（１０１）と、無線基地局（１０１）から送信された共通パイロット信号を受信する携帯端末（１０２）とから構成される無線通信システムにおいて、携帯端末（１０２）は、無線基地局（１０１）から送信されてきた信号の受信品質を測定し、測定した受信品質を無線基地局（１０１）へ送信し、無線基地局（１０１）は、共通パイロット信号が個別チャネルと共通制御チャネルとのどちらを用いて送信するものであるかを当該共通パイロット信号のパイロットパターンに基づいて判断し、共通パイロット信号が個別チャネルを用いて送信するものであると判断した場合、受信品質に応じて共通パイロット信号の送信密度を設定し、共通パイロット信号が共通制御チャネルを用いて送信するものであると判断した場合、共通パイロット信号の送信密度を個別チャネルの送信帯域における送信密度よりも高く設定する。
