Title:
TERMINAL AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2022/141079
Kind Code:
A1
Abstract:
The present disclosure provides a terminal and a base station. The terminal comprises: a control unit, configured to determine at least one group of transform domain vectors, the at least one group of transform domain vectors being used for processing factors associated with a plurality of spatial domain vectors, the plurality of spatial domain vectors being used for determining a precoding matrix for a subcarrier level; and a sending unit, configured to send precoding matrix indication information to a base station, the precoding matrix indication information comprising first information, the first information being used for indicating at least one group of transform domain vectors. The base station comprises: a receiving unit, configured to receive precoding matrix indication information from a terminal, the precoding matrix indication information at least comprising first information, the first information being used for indicating at least one group of transform domain vectors; and a control unit, configured to determine a precoding matrix according to the precoding matrix indication information.
