论文摘要
可重新配置的智能表面（RISS）被认为是第六代（6G）无线网络的有前途的技术，可以以理想的方式控制无线通道并显着提高网络性能。通过利用更高的设计灵活性和全空间覆盖率来克服仅反射riss的同时传输和反射托盘（星际摩托车）。尽管有好处，但由于传输和反射链接的各种控制参数，星际轮胎的建模和分析还是复杂的。在本文中，提出了一个促进6G场景和网络拓扑中星际轮胎设计和实施的一般框架。 We provide a systematic introduction to the STAR-RIS operating protocols for different communication modes and discuss recent efforts to identify the research progress and combination solutions.最后，我们提供了与渠道建模，渠道估计，硬件实现，建模和局限性以及优化相关的设计概念，研究挑战，潜在解决方案以及未来的方向。
Reconfigurable intelligent surfaces (RISs) have been considered as a promising technology for the sixth-generation (6G) wireless networks that can control wireless channels in a desirable way and significantly enhance the network performance. Simultaneous transmitting and reflecting-RISs (STAR-RISs) can overcome limitation of reflecting-only RISs by leveraging the higher design flexibility and full-space coverage. Despite the benefits, the modeling and analysis of STAR-RISs are complicated because of various control parameters for both transmission and reflection links. In this article, a general framework to facilitate the design and implementation of STAR-RISs in 6G scenarios and network topologies is presented. We provide a systematic introduction to the STAR-RIS operating protocols for different communication modes and discuss recent efforts to identify the research progress and combination solutions. Finally, we provide the design concepts, research challenges, potential solutions, and future directions related to the channel modeling, channel estimation, hardware implementations, modeling and limitations, and optimization.
