摘　　要：在未来5G频谱的演进中,部分待扩容频段存在上行高干扰,严重影响用户感知,会对高干扰区域的5G频谱演进带来巨大的挑战。本文基于5G载波聚合技术,研究了一种5G单下行辅载波技术方案,重新激活受干扰频谱的下行资源,满足网络发展对频谱资源的需求,改善用户的体验,具有很高的经济价值。In the future evolution of 5G spectrum,due to the existence of uplink high interference in some frequency bands,it will seriously affect the perception of users,so it will bring huge challenges to the evolution of 5G spectrum in areas with high interference.Based on the 5G carrier aggregation technology,this paper studies a 5G single downlink auxiliary carrier technology,which can reactivate the downlink resources of the interfered spectrum,meet the needs of network development for spectrum resources,improve user experience,and have high economic value.
