Title:
TERMINAL AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/244155
Kind Code:
A1
Abstract:
This terminal comprises: a control unit that assumes, on the basis of a parameter for a non-terrestrial network (NTN) that indicates periods from a downlink data channel to an uplink hybrid automatic repeat request-acknowledgment (HARQ-ACK) feedback, the range of the periods; a reception unit that receives, from a base station, downlink control information (DCI), which is a DCI format 1_0 that has a field that indicates any of the periods, and data scheduled by the DCI; and a transmission unit that transmits, to the base station, HARQ-ACK feedback corresponding to the data.
