Document Type and Number:
Japanese Patent JPWO2018143396
Kind Code:
A1
Abstract:
衝突型ＵＬ送信を適用する場合に適切に通信を行うことが可能なユーザ端末及び無線通信方法を提供すること。本発明のユーザ端末は、無線基地局からのＵＬ送信指示なしにＵＬデータ及び参照信号を送信する送信部と、前記ＵＬデータ及び前記参照信号の送信を制御する制御部と、を有し、前記制御部は、前記参照信号としてユーザ端末を識別できる参照信号を適用し、あらかじめ設定された所定リソースを利用して前記ＵＬデータ及び前記参照信号の送信を制御することを特徴とする。
