摘　　要：毫米波大规模MIMO能够在用户吞吐量和频谱效率等方面发挥巨大的优势,但高能耗和高硬件成本的问题阻碍了系统的实用化进程。智能反射面作为一种低能耗、易部署、可编程的新兴技术,可以有效改善上述问题。IRS与毫米波大规模MIMO的结合在满足6G的绿色通信理念的同时,又有助于实现高速率通信和低功耗通信的愿望。因此结合国内外的最新发展趋势,讨论了毫米波大规模MIMO以及IRS辅助的毫米波大规模MIMO的发展历程、关键技术的特点,并进一步讨论了未来的研究热点以及有待解决的问题。Millimeter-wave massive MIMO can exert great advantages in terms of user throughput and spectral efficiency, but the problems of high energy consumption and high hardware cost hinder the practical process of the system. As an emerging technology with low energy consumption, easy deployment and programmability, intelligent reflecting surface(IRS) can effectively solve the above problems. In order to meet the green communication concept of 6G, the combination of IRS and millimeter-wave massive MIMO contributes to the desire for simultaneous high-rate communication and low-power communication. Therefore, combined with the latest development trends at home and abroad, the development history and characteristics of key technologies of millimeter-wave massive MIMO and IRS-aided millimeter-wave massive MIMO are discussed, and future research hotspots and problems to be solved are further discussed.
