Title
(JA) キャリアアグリゲーションにおけるアップリンクコントロール情報送信方法および装置
Abstract
(JA)

本発明の実施形態は、キャリアアグリゲーションにおけるアップリンクコントロール情報送信方法および装置を提供する。基地局が、第1の表示情報をユーザ機器UEへ送信して、その第1の表示情報に従ってアップリンクコントロール情報UCIを動的に決定するようUEに指示し、基地局は、UCIを送信するためにPUCCHリソースをUEへ割り振る。本発明の実施形態は、キャリアアグリゲーションシナリオにおけるUCI情報のフィードバックを実施し、それによって、有効なUCI情報を送信することのパフォーマンスを改善するために使用され得る。
