Title:
TERMINAL, WIRELESS COMMUNICATION METHOD, AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2024/095427
Kind Code:
A1
Abstract:
A terminal according to one aspect of the present disclosure comprises: a receiving unit that receives a configuration of either a first demodulation reference signal (DMRS) to which a first frequency domain orthogonal cover code (FD-OCC) of length 2 is applied or a second DMRS to which a second FD-OCC of length 4 is applied; and a control unit that determines the size of an antenna port field in downlink control information for scheduling a physical uplink shared channel on the basis of the configuration. This embodiment of the present disclosure makes it possible to use an appropriate number of DMRS ports.
