摘要

摘要：时分双工（time division duplexing，TDD）组网的5G系统面临大气波导效应造成的远端干扰问题。首先，介绍了中国移动2.6 GHz频段5G系统面临的大气波导干扰风险和现状，总结了2.6 GHz频段5G大气波导干扰时频域干扰特征；然后，对5G大气波导干扰测试结果进行了验证分析，包括不同帧偏置、不同业务负载、施/受扰小区不同天线下倾角配置下的大气波导干扰影响分析；最后，通过结果对比得出指导 2.6 GHz频段5G大气波导优化方案的建议。

Abstract

Abstact: 5G (time division duplexing

TDD) system will be effected by the interference from 5G system due to atmospheric duct.The risk and current situation of 5G system in 2.6 GHz band were introduced and the interference characteristics of 5G interference due to atmospheric duct were summarized.Then based on the interference test results of the interference from 5G system due to atmospheric duct

the interference due to atmospheric duct influences under different frame offset

different service load and different antenna dip configuration were analyzed.Finally

the suggestions for the optimization of 5G interference due to atmospheric duct in 2.6 GHz band were obtained.
