摘要
可重构智能表面是6G的潜在关键技术之一,它通过对无线信号的可控反射,可以有效提升期望区域的覆盖性能。得益于其低成本、轻体量等特性,可重构智能表面在6G网络部署中具备很大的潜力。基于可重构智能表面的技术原理以及潜在应用场景,对其在6G中的部署及应用进行了分析,着重聚焦全透明、半透明、非透明智能表面的特性及其在应用部署中的潜在问题。希望相关分析可以起到抛砖引玉的作用,使业界在研究智能表面技术的同时,更加关注它在落地应用时的痛点问题,协同促进相关产业的发展。
Reconfigurable intelligent surface(RIS) is one of the potential key technologies for 6G system, where the coverage performance of desired regions can be effectively improved through the controllable reflection of wireless signals. Due to the low-cost and light-weight features, RIS has great potential in 6G network deployment. Based on the technical principles and potential application scenarios of the RIS, this paper analyzes its deployment and application in 6G, and focuses on the features of fullytransparent, half-transparent and non-transparent RISs and potential issues in application deployment. It is expected that this investigation can motivate more researches on the RIS and enable the industrial field to concentrate more on the pain points in the practical applications and coordinate the development of related industries.
