Abstract

　異なるサブフレーム番号のセカンダリ同期チャネルに乗算するスクランブル符号を変えることにより、隣接セルからの干渉をランダムにするという効果を保ちつつ、移動局装置が保持する必要のある符号数を削減すると共に、移動局装置の回路規模と計算量の削減を図る。基地局装置情報に基づいてプライマリ同期チャネルを生成するプライマリ同期チャネル生成部５０と、基地局装置情報に基づいて第１の信号および第２の信号の組み合わせによって構成されるセカンダリ同期チャネルを生成するセカンダリ同期チャネル生成部５１と、前記セカンダリ同期チャネルに乗算する第１のスクランブル符号を前記プライマリ同期チャネルに基づいて生成する第１のスクランブル符号生成部５２と、前記第２の信号に乗算する第２のスクランブル符号を前記第１の信号に基づいて生成する第２のスクランブル符号生成部５３と、を備える。 <> </>
