摘　　要：本文提出了一种基于MDT大数据优化3D-MIMO天线权值的方法,使得话务热点集中于3D-MIMO天线法线方向,有效改善热点区域用户感知,使3D-MIMO小区尽量吸收更多话务,实现了3D-MIMO投资收益最大化,并为后续面向5G的3D-MIMO大规模建设及优化提供有效依据。This thesis proposes a method to optimize the antenna weight of 3D-MIMO based on MDT,so that the traffic hotspot is concentrated in the normal direction of the antenna to effectively improve the user perception in the hot spot and absorb more traffic as much as possible.It realizes the maximization of 3D-MIMO investment income and provide an effective basis for the subsequent large-scale construction and optimization of 3D-MIMO for 5G.
