摘　　要：首先基于5G NSA的技术特点,提出了从NSA MR获取高精度经纬度信息的技术方案。进一步地,提出了基于MR经纬度信息的Massive MIMO权值智能寻优技术方案,利用智能化权值选择算法在Massive MIMO权值空间中搜索最优解;考虑到现有系统算力的限制,还提出了寻求局部最优解的简化算法,提高了算法的实用性和推广价值。Firstly,based on the technical characteristics of 5G NSA,a technical scheme to obtain high-precision longitude and latitude information from NSA MR is proposed.Furthermore,an intelligent optimization scheme of Massive MIMO weight based on MR latitude and longitude information is proposed,which uses intelligent weight selection algorithm to search the optimal solution in Massive MIMO weight space.Considering the limitation of computing power in existing system,a simplified algorithm to search the local optimal solution is also proposed,which improves the practicability and popularization value of the algorithm.
