Title (EN) USER TERMINAL AND WIRELESS COMMUNICATION METHOD
(FR) TERMINAL UTILISATEUR ET PROCÉDÉ DE COMMUNICATION SANS FIL
(JA) ユーザ端末及び無線通信方法
Abstract:
(EN) The present invention suitably performs beam management (for example, a report and/or instruction of a beam). A user terminal of the present invention is characterized by including: a receiving unit which receives a downlink (DL) control channel for a first search space; and a control unit which specifies a beam used for transmitting and/or receiving the DL control channel for the first search space on the basis of an association of an antenna port for a demodulation reference signal with a mobility measurement signal.
(FR) L'invention permet de réaliser une gestion de faisceaux de manière appropriée (par exemple, un rapport et/ou une instruction d'un faisceau). Selon l’invention, un terminal utilisateur est caractérisé en ce qu'il comprend : une unité de réception qui reçoit un canal de commande de liaison descendante (DL) pour un premier espace de recherche ; et une unité de commande qui spécifie un faisceau permettant d’émettre et/ou de recevoir le canal de commande DL pour le premier espace de recherche d’après une association d'un port d'antenne pour un signal de référence de démodulation avec un signal de mesure de mobilité.
(JA) ビーム管理(例えば、ビームの報告及び/又は指示)を適切に行うこと。本発明のユーザ端末は、第1のサーチスペース用の下りリンク(DL)制御チャネルを受信する受信部と、復調用参照信号のアンテナポート及びモビリティ測定用信号の関連付けに基づいて、前記第1のサーチスペース用のDL制御チャネルの送信及び/又は受信に用いられるビームを特定する制御部と、を具備することを特徴とする。
