(FR) TERMINAL UTILISATEUR ET PROCÉDÉ DE COMMUNICATION RADIO
(JA) ユーザ端末及び無線通信方法
Abstract:
(EN) In order to suitably control RLM when implementation of a beam recovery procedure is assumed, this user terminal is provided with a receiving unit which receives information relating to a virtual downlink control channel, and a control unit which, on the basis of the aforementioned information, controls monitoring of the radio link quality of downlink signals in a first set for which quasi-co-location of the downlink control channel with a demodulation reference signal is assumed, and/or radio link quality of downlink signals in a second set configured by a radio base station.
(FR) Selon la présente invention, afin de commander de manière appropriée le RLM lorsque la mise en œuvre d'une procédure de récupération de faisceau est adoptée, ce terminal d'utilisateur est pourvu d'une unité de réception qui reçoit des informations relatives à un canal de commande de liaison descendante virtuel, et d'une unité de commande qui, sur la base des informations susmentionnées, commande la surveillance de la qualité de liaison radio de signaux de liaison descendante dans un premier ensemble pour lequel la quasi-co-localisation du canal de commande de liaison descendante avec un signal de référence de démodulation est supposée, et/ou la qualité de liaison radio de signaux de liaison descendante dans un second ensemble configuré par une station de base radio.
(JA) ビーム回復手順の実施が想定される場合に、RLMを適切に制御すること。本発明の一態様に係るユーザ端末は、仮想の下り制御チャネルに関する情報を受信する受信部と、前記情報に基づいて、下り制御チャネルの復調用参照信号との疑似コロケーションが想定される第1のセットの下り信号の無線リンク品質、及び/又は、無線基地局によって設定される第2のセットの下り信号の無線リンク品質のモニタリングを制御する制御部と、を具備する。
