Description
・ATのアクティブセット内のパイロット。
・ATが送信する周波数。
・<FeedbackMultiplexingIndex,RL fuequencies>。ここで、“FeedbackMultiplexingIndex”は、多数の順方向リンク(FL)に関連する、例えばセル選択、ハイブリッド自動反復要求(ARQ)アクノレッジメント(ACK)、信号対雑音干渉比率(C/I)フィードバック等のような
情報が、どのようにして単一の逆方向リンク(RL)チャネルに多重化されるかを示す。
・ATのアクティブセット内の各セクタ/セルに対するデータレート制御(DRC)カバーおよびDSC。
・(例えば、図8に例示するように)パイロットに関連付けられたスケジューラタグが、同じである。
・パイロットが、(そのDRCカバーを示す潜在的なセクタを含みうる)ATの同じサブアクティブセットにあり、(例えば、TCAメッセージにおいて識別されるように)互いにソフタハンドオフしているセクタ(例えば、セクタBおよびセクタC)に属している。
