Abstract
(EN)
A terminal according to an aspect of the present disclosure comprises: a control unit that, in a case where the terminal supports two active transmission configuration indications (TCIs) for physical downlink control channel (PDCCH) and two TCI states are activated for PDCCH, determines, as TCI state for physical downlink shared channel (PDSCH), one TCI state indicated by an activation command; and a reception unit that receives a PDSCH on the basis of the TCI state for PDSCH. According to an aspect of the present disclosure, a TCI state for PDSCH is appropriately determined.
(FR)
Selon un aspect, la présente invention concerne un terminal comprenant : une unité de commande qui, dans un cas où le terminal prend en charge deux indications de configuration de transmission (TCI) actives pour un canal de commande de liaison descendante physique (PDCCH) et deux états TCI sont activés pour un PDCCH, détermine, en tant qu'état TCI pour un canal partagé de liaison descendante physique (PDSCH), un état TCI indiqué par une commande d'activation ; et une unité de réception qui reçoit un PDSCH sur la base de l'état TCI pour le PDSCH. Selon un autre aspect de la présente invention, un état TCI pour le PDSCH est déterminé de manière appropriée.
(JA)
本開示の一態様に係る端末は、端末が物理下り制御チャネル(PDCCH)用の2つのアクティブ送信構成指示(TCI)をサポートし、且つPDCCH用に2つのTCI状態がアクティベートされる場合、アクティベーションコマンドによって指示される1つのTCI状態を、物理下り共有チャネル(PDSCH)用TCI状態として決定する制御部と、前記PDSCH用TCI状態に基づいてPDSCHを受信する受信部と、を有する。本開示の一態様によれば、PDSCH用のTCI状態を適切に決定する。
