Title:
TERMINAL AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/230860
Kind Code:
A1
Abstract:
A user terminal according to one aspect of the present disclosure is characterized by having: a reception unit that receives a first physical downlink shared channel (PDSCH) from a first transmission/reception point (TRP) and a second PDSCH which is from a second TRP and which overlaps with the first PDSCH in a time resource and/or a frequency resource; and a control unit that, on the basis of downlink control information for scheduling the first PDSCH and/or the second PDSCH, performs first control for transmitting, to the first TRP, a first hybrid automatic repeat request acknowledgement (HARQ-ACK) with respect to the first PDSCH and transmitting, to the second TRP, a second HARQ-ACK with respect the second PDSCH and performs second control for transmitting both of the first HARQ-ACK and the second HARQ-ACK to one of the first TRP and the second TRP.
