摘要/Abstract

摘要： 随着元材料和元表面等相关研究的进一步发展，智能反射面（IRS）的概念被提出。IRS利用集成在平面上的大量无源反射元件通过软件编程智能地配置无线传播环境，从而达到提高无线通信系统性能的目的，相对于传统的中继系统具有成本低、功耗低、易部署等特点。因此，IRS及IRS辅助无线通信是未来通信领域发展的重要技术之一。通过对现有IRS研究现状的调查和整理，从IRS的基本概念、发展历程、特性优势和IRS辅助无线通信的基本概念、研究方向等方面，详细介绍了IRS与IRS辅助无线通信的发展与应用。最后对IRS未来的发展进行展望。

Abstract: With the further development of related research on metamaterials and metasurfaces, the concept of Intelligent Reflecting Surface (IRS) was proposed. IRS uses a large number of passive reflective elements integrated on the plane to intelligently configure the wireless propagation environment through software programming, so as to improve the performance of the wireless communication system. Compared with the traditional relay base station, IRS has the advantages of low cost, low power consumption and easy deployment. Therefore, IRS and IRS-assisted wireless communication are one of the important technologies in the future development of the communication field. By investigating and sorting out the current status of IRS research, the development and applications of IRS and IRS-assisted wireless communication are introduced in terms of the basic concepts, development history, characteristics and advantages of IRS, and the basic concepts and research directions of IRS-assisted wireless communication. Future development of IRS is also discussed.

Key words: intelligent reflecting surface, wireless communication, the 6th generation mobile communication technology (6G), massive MIMO, internet of thing
