3 D-MIMO technology is one of the key technologies of 4 G+ and 5 G

which has obvious advantages in high frequency coverage

capacity and user perception. Based on the beam level throughput and interference measurement in MR data

this paper accurately identifies the user distribution in the coverage area

optimizes the cell azimuth

and iteratively optimizes the antenna weight according to the characteristics of different scenarios. According to the results of "potential users" and "lost users"

this paper estimates the throughput gain brought by the combination of each group of weights and dip angle

and realizes different scenarios. The best weight confi guration scheme of 3 D-MIMO.
