摘　　要：在5G超密集网络UDN部署的低功率节点覆盖下,小区覆盖重叠严重导致了小区间存在较大的同层干扰,由用户话务在时间和空间上分布不均匀而产生的小区负载不均衡造成了小区网络资源的严重浪费,小区用户体验大幅度降低。基于5G网络和TDD-CoMP技术的新特征,构建了一种以用户为中心的5G分布式联合传输模型,对模型中的干扰、功耗以及速率解决方案进行了分析,最后得出一种可有效降低系统能耗,提升用户整体的速率的5G分布式联合传输策略研究方案。Under the coverage of low-power nodes deployed in 5G ultra-dense networks (UDN),the overlapping of cell coverage severely leads to the co-tier interference.The cell load imbalance caused by the uneven temporal-spatial distribution of user traffic results in the serious waste of cell network resources,and thus the cell user experience is greatly reduced.Based on the new features of 5G network and TDD-CoMP technology,this paper establishes a user-centric 5G distributed joint transmission model,and analyzes the interference,power consumption and rate solutions in the model.Finally,a 5G distributed joint transmission strategy research solution is proposed to effectively reduce system energy consumption and increase the overall rate of users.
