TERMINAL, WIRELESS COMMUNICATION METHOD, AND BASE STATION

Title:

TERMINAL, WIRELESS COMMUNICATION METHOD, AND BASE STATION

Document Type and Number:

WIPO Patent Application WO/2024/106429

Kind Code:

A1

Abstract:

A terminal according to one aspect of the present disclosure comprises: a reception unit which receives setting of a first demodulation reference signal (DMRS) to which a frequency domain orthogonal cover code (FD-OCC) longer than 2 is applied, and receives a downlink control information format including an antenna port field; and a control unit which determines a combination corresponding to the value of the antenna port field on the basis of one association out of a first association that associates multiple combinations of multiple ports including a port for the first DMRS and corresponding to multiple transmission/reception points with multiple values of the antenna port field, and a second association that associates multiple combinations of multiple ports including the port for the first DMRS and corresponding to one transmission/reception point with multiple values of the antenna port field.
