智能超表面中继的系统方案设计

Reconfigurable Intelligent Surface System Scheme Design

作为6G的潜在关键技术之一,智能超表面(Reconfigurable Intelligent Surface, RIS)通过改变电磁波的电磁特性,可以智能地重构无线传播环境。研究RIS的方案设计在提高系统性能、扩大应用范围、提高部署灵活性等方面有重要意义。要将RIS部署到未来的无线网络中,需要前期在标准化组织,例如3GPP中进行重要的标准化研究工作。虽然许多论文都在研究如何优化RIS及其性能限制,但很少有论文研究RIS标准化方案设计。因此,介绍RIS辅助通信的方案设计,包括初始接入方案、半静态节能控制方案、码本设计方案等,为未来的RIS标准化方案设计提供一定的参考。

As one potential key technology of 6G,Reconfigurable Intelligent Surface(RIS)can intelligently reconfigure wireless propagation environment by changing electromagnetic characteristics of electromagnetic waves.It is important to study the scheme design of RIS to improve system performance,expand application range and improve deployment flexibility.Deploying RIS into future wireless networks require significant prior standardization work in standardization organizations such as3GPP.While many research papers have investigated how to optimize RIS and their ultimate performance limits,few papers have investigated RIS standardized scheme design.Therefore,this paper will introduce the scheme design of a RIS assisted communication system,including initial access scheme,semi-static energy saving control scheme,codebook design scheme,etc.,to provide a certain reference for the future RIS standardization scheme d esign.
