Title:
TERMINAL AND SENDING DEVICE IN COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/092361
Kind Code:
A1
Abstract:
Provided in the present disclosure are a terminal and a sending device in a communication system. The sending device comprises: a receiving unit, which is configured to receive position information of a terminal; and a control unit, which is configured to determine a first codeword in a first codebook and offset information according to the position information, wherein the first codeword indicates initial phases of at least some array elements in a reconfigurable intelligent surface (RIS), and the offset information indicates an offset relative to at least one of the at least some array elements, the initial phases, and a reference position of the RIS.
