As One of the key technologies for the next generation mobile cellular network（5 G）

with high spectral efficiency and energy efficiency

Massive MIMO can significantly improve the throughput of the system. On the research of 4 G

the main digging performance of Massive MIMOis thebeamforming on downlink

receive diversity enhancement on uplink as well as other aspects of three-dimensional adjustable on beam. Through the analysis of Massive MIMO 4 G technology standards progress and product testing

deeply validate its technical superiority

pointed out the problems and propose solution ideas

and summarize the Massive MIMO 4 G technology applications recommended scenarios and provide some guidance for technical follow-up research and scale applications.
