Abstract

　リファレンス信号のマッピング位置が周波数方向及び時間方向に変化する次世代移動通信システムにおいて、隣接するセルのリファレンス信号のマッピング位置を出来る限り異なるように設定する。 　基地局装置は、下りリンクにOFDM方式を用いる移動通信システムで使用される。基地局装置は、第１の信号を生成する手段（２０２）と、第２の信号を生成する手段（２１４）と、前記第１信号と第２信号を多重してサブキャリアにマッピングする手段（２０６）と、前記第２の信号がマッピングされるサブキャリアの位置を決定するマッピング決定部（２１６）とを有する。マッピング決定部は、それぞれがセルグループのＩＤに関連づけられた、二段階の系列で定義されるマッピングパターンに基づいて、第２信号がマッピングされるサブキャリア位置を決定する。
