700 MHz 5G干扰规避解决方案

Discussion on 700 MHz 5G interference avoidance solution

中国移动与中国广电700 MHz签署共建共享协议,在全国范围内大规模部署700 MHz 5G移动通信网络。针对700 MHz 5G NR基站干扰问题,本文通过700 MHz干扰图谱自动识别定位,实施智选调度、独立解调和上行底噪抑制的干扰规避解决方案,降低带内干扰,保障700 MHz 5G通信质量和用户体验。外场测试和后台评估表明,干扰规避措施有效抑制700 MHz部分频段干扰,对于指导700 MHz 5G精品网络工程建设具有参考价值。

China Mobile and China Broadcasting Network 700 MHz signed a joint construction and sharing agreement to deploy a 700 MHz 5G mobile communication network nationwide on a large scale.Aiming at the interference problem of 700 MHz 5G NR base station,this paper automatically identifies and locates the 700 MHz interference map,implements the interference avoidance solution of smart scheduling,independent demodulation and uplink noise cancellation,reduces in-band interference,and ensures the quality and user experience of 700 MHz 5G.Field tests and background evaluations show that interference avoidance measures can eff ectively suppress interference in the 700 MHz part of the frequency band,which is of reference value for guiding the construction of 700 MHz 5G boutique network projects.
