摘　　要：近年来,5G网络部署进行得如火如荼,NSA组网作为5G部署的一种过渡性方案,最终会被SA组网替代。但是从节省初期投入的角度来看,NSA组网不可或缺,甚至将长期与SA和LTE共存。AAU共模并发场景作为NSA组网方式的一种典型应用,必然造成NR与LTE间的小区干扰。经过分析与仿真研究,本文提出一种通过配置合理的功率配置比来降低干扰,提升NSA组网小区信号性能的方法。NSA as a 5G deployment of a transitional scheme,will eventually be replaced by SA network with full swing of 5G network deployment in recent years.But the NSA network is indispensable and even long-term coexistence with SA and LTE from the point of view of saving the initial investment.As a typical application of NSA,AAU common-mode concurrency will inevitably cause cell interference between NR and LTE.After analysis and simulation research,a method is proposed to reduce interference and improve the performance of NSA cell network by configuring a reasonable power allocation ratio.
