Abstract

　参照テーブルの設定や１つのセルへの割当系列数に依存せずに、所望の最大送信電力で送信可能なＣＭ値をもつコード系列をセルに割り当て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およびＣＭ値とインデックス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、割当インデックス番号、巡回シフト量ＮＣＳ及びＣＭ閾値ＴＨＣＭ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。
