RIS近场码本和波束管理
Near-field Codebook and Beam Management for RIS
摘要
Abstract
This article explores the application of Reconfigurable Intelligent Surface(RIS)in near-field codebook design and beam management.RIS technology significantly improves signal coverage and transmission efficiency by deploying controllable intelligent sur-faces in wireless communication environments.The article first outlines the basic principles and application scenarios of RIS,and then delves into its codebook design strategy in near-field environments,with a focus on how to allocate beam resources to meet different sig-nal transmission requirements.Furthermore,the article validated the performance of RIS near-field and far-field codebooks at different distances through simulation experiments,demonstrating the effectiveness of the proposed scheme in improving system performance in practical networks and providing new ideas and solutions for future wireless communication system design.关键词
