Title:
TERMINAL, WIRELESS COMMUNICATION METHOD, AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2022/176157
Kind Code:
A1
Abstract:
According to one aspect of the present disclosure, a terminal has: a reception unit that receives downlink control information (DCI) that indicates one or more transmission configuration indicator (TCI) states that can be applied to a plurality of types of channels for a plurality of serving cells; and a control unit that, on the basis of the reception timing of the DCI or transmission timing for a hybrid automatic repeat request acknowledgement (HARQ-ACK) for the DCI, determines the length of time to application of the one or more TCI states. One aspect of the present disclosure makes it possible to appropriately perform TCI state indication.
