摘要
大气波导效应会对TDD移动通信系统产生较强干扰。首先分析了大气波导干扰的特征和识别方法,研究了大气波导对5G NR影响的关键因素。结合3GPP标准组织的工作进展,论述了几种典型的大气波导干扰消除技术框架和技术方案,给出了后续工作建议。
Atmospheric duct effect can produce strong interference to TDD mobile communication system.Firstly,the feature and related recognition methods of atmosphere dust interference are analyzed.Furthermore,the key factors affecting 5G NR in atmospheric duct are studied.Based on the introduction of related research of 3GPP,some frameworks and schemes of atmospheric duct interference cancellation are brought out.At last,some suggestions are given.
