Abstract

　上り回線のチャネル品質測定の精度を劣化させることなく無線通信装置の消費電力を抑止できるとともに周波数利用効率の高い状態で、上り回線のチャネル品質測定用パイロット信号送信させる基地局装置。この装置(2)では、リソースブロックサイズ決定部(54)にて無線通信装置(1)に割り当てるサブキャリア数を決定して、巡回シフト遅延量決定部(55)にて、巡回シフト遅延ダイバーシチ送信する際の巡回シフト遅延量をリソースブロックサイズ決定部(54)により決定されたサブキャリア数に応じて設定する。巡回シフト遅延量決定部(55)にて設定された巡回シフト遅延量を用いて、無線通信装置(1)は、チャネル品質測定用信号を巡回シフト遅延ダイバーシチ送信する。
