Abstract

　隣接する複数のセルに対し互いに異なる系列を割り当てることができるという系列割当の自由度、すなわち、セルプランニングの自由度を維持しつつ、割当系列情報の通知に必要なビット数を削減することができる系列通知装置。この装置において、プリアンブル系列記憶部（１１３）は、割り当て可能な複数のプリアンブル系列を記憶するとともに、複数のプリアンブル系列の系列番号と複数のプリアンブル系列のグループを示すグループ番号との対応付けが設定された参照テーブルを記憶し、割当系列取得部（１１８）は、割当系列数を示す情報、割当グループ番号および通知されたセルＩＤに基づいて、プリアンブル系列記憶部（１１３）に記憶された参照テーブルを参照し、セルに割り当てられたプリアンブル系列をプリアンブル系列記憶部（１１３）から取得してプリアンブル系列検出部（１１４）に出力する。
