Title:
TERMINAL, WIRELESS COMMUNICATION METHOD, AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2024/034091
Kind Code:
A1
Abstract:
A terminal according to one aspect of the present disclosure comprises: a reception unit that receives downlink control information (DCI) for scheduling an uplink shared channel; and a control unit that selects, on the basis of a specific field of the DCI, an antenna port indication table relating to a demodulation reference signal (DMRS) port indication for the uplink shared channel from among a plurality of tables for a certain rank. According to the one aspect of the present disclosure, it is possible to appropriately determine a DMRS port.
