Title:
TERMINAL, WIRELESS COMMUNICATION METHOD, AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2024/106428
Kind Code:
A1
Abstract:
A terminal according to one embodiment of the present disclosure includes: a reception unit that receives the setting of a first demodulation reference signal (DMRS) to which is applied a frequency domain orthogonal cover code (FD-OCC) that is longer than 2, and that receives a downlink control information format which includes an antenna port field; and a control unit that determines a combination corresponding to a value of the antenna port field, on the basis of the association between a plurality of values of the antenna port field and a plurality of combinations of a plurality of ports containing a port of the first DMRS.
