Title:
USER TERMINAL AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/230862
Kind Code:
A1
Abstract:
In order to appropriately control at least one of the feedback and determination of an HARQ-ACK codebook, a user terminal according to an embodiment of the present disclosure comprises: a control unit which, if different sub-carrier intervals are to be set in an uplink and a downlink, determines at least one candidate occasion set for reception of a downlink shared channel in a prescribed number of first time intervals, on the basis of a hybrid automatic repeat request-acknowledge (HARQ-ACK) timing value shown in a number of first time units shorter than an uplink slot; and a transmission unit which transmits a codebook determined on the basis of the candidate occasion set.
