摘要
根据中国5G NR的频率使用方案,本文首先重点分析了2.6 GHz频段与4.9 GHz频段上5G NR上行面临的干扰风险,为5G NR规避相关干扰提供指导.然后通过外场干扰测试,掌握了5G NR网络性能与干扰强度间的关系,给出了全频带严重干扰时的5G NR干扰门限建议和NSA组网时的LTE锚点受扰门限建议.根据上述研究结果,本文提出了适合SA和NSA两种组网方式的5G NR干扰分析方法,为5G NR干扰分析的集中化和自动化提供指导.
According to the frequency usage scheme of China,this paper researches on the uplink interference risk of 5G NR at both 2.6 GHz and 4.9 GHz frequency range.Then based on the outdoor interference test,the relationship between 5G NR network performance and interference level is clarifi ed and the proposed interference threshold of 5G NR and LTE anchor are given.This paper proposes an interference analysis method adapting to both SA and NSA,which could guide the interference analysis and optimization of 5G NR.
