摘　　要：随着移动通信技术的发展,移动用户设备呈爆炸性增长趋势,使异构网中小区密集,造成小区间严重干扰,严重影响系统吞吐量。基于5G超密异构网络结构,研究了以用户为中心,基于动态小区选择与联合优化,提出了联合虚拟波束形成的小区选择算法。仿真结果表明:该算法协调了小区间干扰和频谱效率的矛盾,提高了边缘用户的性能和小区的平均吞吐量。With the development of mobile communication technology, mobile user equipment show explosive growth trend,village populated in heterogeneous network, which causes serious interference between zones, and seriously affect system throughput. Therefore, based on 5G superdense heterogeneous network structure, study user- centric based on distributed virtual communities of dynamic selection and joint optimization of community, put forward joint area selection algorithm of virtual beamforming. Simulation results show that the algorithm coordinates conflict between interference between zones and spectrum efficiency, improve performance of edge users and average throughput of cell.
