摘要

远端干扰主要来源于大气波导传播，是造成大气波导现象高发地区5G NR移动通信网络性能劣化的原因之一。在分析研究时分双工无线网络远端干扰产生机理的基础上，针对性地论述了两类远端干扰管理的方案。在大气波导高发地区5G NR网络中针对静态增加GP（guard period）方案进行了验证。网络运行数据表明，改变无线时隙子帧格式，增加隔离符号可以有效地避免远端干扰，提升全网性能。

Abstract

Remote interference mainly comes from the atmospheric ducting transmission.It is one of the reasons for the deterioration of the fifth-generation new radio (5G NR) mobile networks.Based on the analysis of the generation mechanism for the remote interference

two solution schemes were accordingly described for the remote interference management.The static increase GP (guard period) scheme was verified in the 5G NR network in areas with high atmospheric wares.Network operation data shows that the increasing guard period could avoid remote interference efficiently and thus improve the quality of the fifth-generation new radio networks.
