论文摘要
可重新配置的智能表面（RISS）被认为是一种有希望的新兴硬件技术，可以通过人工重新配置电磁波的传播环境来提高无线网络的频谱和能源效率。由于增强无线通道容量的独特优势，RIS最近已成为一个热门研究主题。在本文中，我们重点介绍将RISS纳入无线网络的三个基本物理层挑战，即渠道状态信息获取，被动信息传输和低复杂性强大的系统设计。我们总结了最先进的解决方案并探索潜在的研究方向。此外，我们讨论了RISS的其他有希望的研究指示，包括Edge Intelligence和Byshlet-Layer Security。
Reconfigurable intelligent surfaces (RISs) are regarded as a promising emerging hardware technology to improve the spectrum and energy efficiency of wireless networks by artificially reconfiguring the propagation environment of electromagnetic waves. Due to the unique advantages in enhancing wireless channel capacity, RISs have recently become a hot research topic. In this article, we focus on three fundamental physical-layer challenges for the incorporation of RISs into wireless networks, namely, channel state information acquisition, passive information transfer, and low-complexity robust system design. We summarize the state-of-the-art solutions and explore potential research directions. Furthermore, we discuss other promising research directions of RISs, including edge intelligence and physical-layer security.
