【Abstract】 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.更多还原
