摘　　要：大规模天线技术(Massive Multiple Input Multiple Output,Massive MIMO)作为5G新空口的关键技术之一,具有高容量、高增益以及灵活的波束赋形等特点。5G Massive MIMO的窄波束和可调整的动态下倾角不仅进一步提高信号的覆盖深度,还可以降低小区间的干扰。文章介绍5G Massive MIMO的窄波束分类,提出不同场景下波束的规划方案,并介绍5G下倾角,列出不同波束的下倾角计算方法,为5G网络的设计、建设以及日常优化提供参考。As one of the key technologies of the new 5G air interface,Massive Multiple Input Multiple Output(Massive MIMO)has the characteristics of high capacity,high gain and flexible beamforming.The narrow beam and adjustable dynamic dip angle of 5G Massive MIMO not only further improve the coverage depth of the signal,but also reduce the interference between cells.This paper first introduces the narrow beam classification of 5G Massive MIMO,puts forward beam planning schemes in different scenarios,and then introduces the downward dip angle of 5G,and lists the calculation methods of downward dip angle of different beams,which provides reference for the design,construction and daily optimization of 5G networks.
