4G/5G共模协同权值优化方法的研究

Research of 4G/5G Common-mode Coordination Weight Optimization Method

随着5G多频段组网的开始,天面资源日益紧张,5G建设主要在4G站址上共模改造新建5G,同时替换4G的D频段设备并反向开通LTE的Massive MIMO。该组网场景下4G和5G共模共天馈,可以实现4G/5G共AAU场景下的天馈协同优化。重点研究了4G/5G共AAU场景下的天馈协同优化方案,以路测和测量报告等数据为输入源,对弱覆盖、高干扰和重叠覆盖区域进行识别,并联动寻优天线覆盖场景的最佳权值、方位角和下倾角等参数,达到4G/5G综合覆盖性能最优。

With the beginning of 5G multi-band networking,antenna resources are increasingly insufficient.5G construction involves comode reconstruction on 4G sites,replaces the 4G frequency band D equipment,and deploys the LTE massive MIMO.In this networking scenario,4G and 5G co-mode share the same antenna system,and antenna coordination optimization can be implemented when 4G and 5G share the same AAU.This document focuses on the antenna coordination optimization solution in4G/5G co-AAU scenarios.It uses drive tests and measurement reports as input sources to identify areas with weak coverage,high interference,and overlapping coverage.In addition,parameters such as the optimal weight,azimuth,and downtilt in antenna coverage scenarios are jointly optimized to achieve optimal 4G/5G comprehensive coverage performance.
