5G干扰特征识别及解决方案研究

Research on 5G Network Interference Characteristics Recognition and Solution

当5G网络中存在严重的上行干扰信号时,小区内用户上下行业务会受到影响,严重时会导致小区无法接入,影响用户的感知体验。重点介绍了NSA网络下5G各类上行干扰形成的主要原因,并从多个维度分析各干扰类型的时域、频域等典型特征,重点研究不同干扰类型的针对性解决方案,降低网络中的系统内外干扰,提升5G用户的感知体验。

When there is serious uplink interference signal in 5G network,the uplink and downlink services of users under the cell will be affected,In serious cases,the cell cannot be accessed,Affect users'perception experience,This paper focuses on the formation of 5G uplink interference types in NSA networks,The typical characteristics of each interference type in time domain and frequency domain are analyzed from multiple dimensions.It focuses on different interference types of targeted solutions to reduce the interference inside and outside the system in the network and enhance the perception experience of 5G users.
