[Abstract] Millimeter wave massive multiple-input multiple-output (MIMO) wireless transmission is a promising technology for future wireless communications as it can expand the use of new spectrum resources, efficiently exploit the space domain wireless resources, and significantly improve the wireless data transmission rate. Based on the millimeter wave massive MIMO architecture, this paper presents a brief overview of the key techniques in millimeter wave massive MIMO wireless communications, including channel modeling, channel information acquisition, multiuser transmissions, and joint resource allocation.
