Abstract
【解決手段】無線デジタル符号分割多重アクセス技術を使用する方法およびシステムであって、基地局がユーザ装置UEから受信したすべてのタイム・スロットでアップリンク干渉を測定し、アップリンク制御チャネルに対する要求を決定する、改善された無線資源の利用率を達成し、ユーザ・サービスにより高いデータ転送速度を提供するために適応変調および符号化が利用される方法およびシステム。基地局は、タイム・スロットのアップリンク干渉と、場合によっては品質マージンの指示を示す特定のアップリンク制御チャネルの割り振りをUEに送信する。UEは、UEによってなされた経路損失決定と、アップリンク干渉と、任意選択の品質マージンとに基づいて適切なアップリンク電力レベルを決定する。次いでUEは、これらの決定に応答してアップリンク通信を開始する。
