论文摘要
可重新配置的智能表面（RISS）或智能反射表面（IRS）被认为是提高无线系统频谱和/或能源效率的最有前途和革命性的技术之一。这些设备能够通过仔细调整大量低成本被动反射元件的相移来重新配置无线传播环境。在本文中，我们的目的是回答四个牺牲问题：1）为什么我们需要RISS？ 2）什么是RI？ 3）RIS的应用是什么？ 4）哪些相关挑战和未来的研究方向？作为回应，指出了八个有前途的研究方向。
Reconfigurable intelligent surfaces (RISs) or intelligent reflecting surfaces (IRSs), are regarded as one of the most promising and revolutionizing techniques for enhancing the spectrum and/or energy efficiency of wireless systems. These devices are capable of reconfiguring the wireless propagation environment by carefully tuning the phase shifts of a large number of low-cost passive reflecting elements. In this article, we aim for answering four fundmental questions: 1) Why do we need RISs? 2) What is an RIS? 3) What are RIS's applications? 4) What are the relevant challenges and future research directions? In response, eight promising research directions are pointed out.
