AI Technical Summary

Technical Problem

Current codebook designs in MIMO systems primarily focus on single-angle dimensions and fail to meet the needs of precoding performance and communication quality in short-range communication scenarios, particularly in large-scale antenna deployments, leading to deteriorated channel estimation quality and system capacity.

Method used

A channel information feedback method that employs multi-domain codebook design, where codewords consist of multiple codeword blocks, and instruction parameters for precoding are interrelated, reducing the number of parameters to be fed back and improving feedback accuracy and reducing transmission load.

Benefits of technology

Enhances the convenience and accuracy of channel information feedback, improving precoding performance and communication quality in diverse scenarios by utilizing interrelated instruction parameters and reducing the number of feedback parameters.

Abstract

This disclosure relates to the telecommunications technology and provides a channel information feedback method, apparatus, and storage medium that can improve the convenience and accuracy of channel information feedback. The channel information feedback method includes the steps of: acquiring channel information; determining a target codeword from a codebook set based on the channel information, wherein the codebook set includes a plurality of codewords, and each codeword consists of one or more codeword blocks; and transmitting instruction parameters for the target codeword.
