Title:
PRE-CODING METHOD AND APPARATUS BASED ON RECONFIGURABLE INTELLIGENT SURFACE
Document Type and Number:
WIPO Patent Application WO/2024/044990
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application are a precoding method and apparatus based on a reconfigurable intelligent surface. The method comprises: acquiring unit arrangement information and blocking information of a second network device, wherein the blocking information is used for indicating a plurality of blocks of the second network device; receiving channel feedback information sent by a terminal device; determining first indication information according to the channel feedback information, the unit arrangement information and the blocking information, wherein the first indication information is used for determining a phase shift matrix of the second network device; and sending the first indication information to the second network device. Therefore, units of a second network device can be divided into a plurality of groups, such that a far-field assumption is established for each group; in addition, the complexity of precoding based on a reconfigurable intelligent surface is effectively reduced, the communication efficiency of a communication system assisted by the reconfigurable intelligent surface is improved, and the interference is reduced.
