摘　　要：Massive MIMO是5G的关键技术之一,相比传统MIMO技术,Massive MIMO不仅增加了垂直方向的波束赋形,且根据不同场景设计了不同的波束方案。通过分析波束赋形实现原理,结合实际场景情况,应用波束水平和垂直波瓣宽度计算公式,选择最佳覆盖场景设置,并选择实际场景进行波束优化试验,总结不同场景的波束优化案例。Massive MIMO is one of the key technologies of 5G.Compared with traditional MIMO technology,Massive MIMO not only increases the beamforming in the vertical direction,but also designs different beams according to different scenarios plan selection.By analyzing the beamforming realization principle and combining the actual scene conditions,the calculation formulas of the beam horizontal and vertical lobe widths are used to select the best coverage scene settings,and the actual scene is selected for beam optimization test,which summarizes the beam optimization cases in different scenarios.
