TERMINAL, WIRELESS COMMUNICATION METHOD, AND BASE STATION

Title:

TERMINAL, WIRELESS COMMUNICATION METHOD, AND BASE STATION

Document Type and Number:

WIPO Patent Application WO/2024/047870

Kind Code:

A1

Abstract:

A terminal according to one aspect of the present disclosure includes: a reception unit that receives information associated with a frequency domain orthogonal cover code (FD-OCC) and receives an antenna port field, said FD-OCC being one of a first FD-OCC with a length of two and a second FD-OCC with a length longer than 2; and a control unit that uses the information as a basis to determine a parameter using a first association between the value of the antenna port field and the parameter or a second association between the value and the parameter. This aspect of the present disclosure makes it possible to use an appropriate number of DMRS ports.
