摘要
为解决现有5G网络覆盖评估手段单一、评估准确性低和评估低效的问题,本文提出基于二维空间和4GMDT的5G覆盖预测算法研究与应用。该算法基于无线传播模型,首先建立5G终端理论接收功率模型,进而结合路测数据从距离和方向角实施基于二维空间的修正建模,从而得到基于二维空间和4GMDT的5G覆盖实际测算模型,最后结合栅格化处理,有效输出5G覆盖评估,提高了5G覆盖评估准确性,填补了5G覆盖栅格化评估的技术空白,指导运营商有针对性地开展4G/5G协同优化。
In order to solve the problem that the existing 5G network coverage evaluation means are single, the evaluation accuracy is low, and the evaluation efficiency is low, this paper proposes the research and application of 5G coverage prediction algorithm based on 2D space and 4G MDT. The algorithm is based on the wireless propagation model. First, the theoretical receiving power model of the 5G terminal is established. Then, combined with the road test data, the modified modeling based on two-dimensional space is implemented from the distance and bearing angle, so as to obtain the actual measurement model of 5G coverage based on two-dimensional space and 4G MDT. Finally, combined with the grid processing, the effective output 5G coverage evaluation is achieved, which improves the accuracy of 5G coverage evaluation, and fi lls the technical gap of 5G coverage grid evaluation, guide operators to carry out targeted 4G/5G collaborative optimization.
