摘　　要：本文基于4G/5G数据挖掘分析,给出了一种NSA组网下5G Massive MIMO天线权值智能优化方法。该方法结合4G MDT和5G MR数据,通过聚类和成形算法分析得到待优化小区理想权值集合,可以在海量权值因子中快速寻优得到最优权值组合,采用基于风险控制的调整算法实现Massive MIMO天线权值智能自动化迭代寻优。This paper proposed a method based on 4G/5G data mining to realize the intelligent optimization of 5G Massive MIMO antenna weight in NSA network.Combined with 4G MDT and 5G MR data,the ideal antenna weight set of the region to be optimized was obtained by clustering and shaping algorithm.The optimal weight combination can be obtained more fast among massive weight factors,and the intelligent automatic iterative optimization of Massive MIMO antenna weight was realized by tuning algorithm based on risk control.
