摘　　要：5G专网因其可定制化、性能稳定、安全可靠等特点成为各行各业的新型信息化基础设施,同时行业基于对业务稳定性、确定性、节能、低成本等方面更高的要求,迫切需要5G专网能够实现相比公网更加精准高效的覆盖。以自动化立体仓库作为典型行业业务场景,提出一种通过搭建小型实验环境对传播模型校正来提升5G专网精准覆盖的方法。基于对自动化立体仓库典型空间的天线增益进行精细化建模仿真,结合典型测试环境的RSRP(reference signal receiving power)测试数据实现对传播模型的精准校正,按照行业终端的业务SLA(service-level agreement)要求可得到通用不同尺寸自动化立体仓库的5G专网精准覆盖参数。5G private network has become a new information infrastructure in all trades and professions because of its customizability,stable performance,safety and reliability.At the same time,due to the industry's higher requirements for business stability,certainty,energy conservation and low cost,5G private network is urgently needed to achieve more accurate and efficient coverage than the public network.Taking the automated warehouse as a typical industry business scenario,a method to improve the accurate coverage of 5G private network by building a small experimental environ-ment and optimizing the propagation model was proposed.Based on the refined modeling and simulation of the antenna gain of the typical space of the automated three-dimensional warehouse,combined with the test RSRP(Reference Signal Receiving Power)data of the typical space,the propagation model can be accurately corrected.According to the service level agreement(SLA)requirements of the industry terminal,the 5G private network accurate coverage parameters common to automated three-dimensional warehouses of different sizes can be obtained.
