可重构智能表面技术:研究进展、原型机及挑战

Reconfigurable Intelligent Surface:Research Progress,Prototypes and Challenges

可重构智能表面(Reconfigurable Intelligent Surface,RIS)是6G的潜在关键技术之一,得益于其低成本、轻体量等特性,RIS在6G网络部署中具备很大的潜力。目前,业界关于RIS的研究主要集中在两个方向:基于RIS的无线收发机以及基于RIS的反射面。针对这两种RIS形态,分别对其研究进展、国内外原型机的测试验证情况以及面临的主要挑战进行了全面的阐述及分析。基于分析可以看出,虽然RIS相关研究取得了一定的积累与成果,但是仍面临许多亟待解决的挑战与痛点问题。

Reconfigurable intelligent surface(RIS)is one of the potential key technologies for 6G system.Benefit from the feature of low cost and weight,RIS has great potential in 6G network deployment.Currently,research on RIS is mainly focus on RIS⁃based wire⁃less transceivers and RIS⁃based reflector.Research progress,testing and verification of RIS prototypes and main challenges for RIS are comprehensively explained and analyzed.Based on the analysis,it can be seen that although RIS⁃related research has achieved certain a⁃chievement,RIS still faces many challenges and pain points to be resolved.
