5G超密集异构网络的上行性能提升方案

Uplink Performance Improvement Scheme for 5G Ultra-Dense Heterogeneous Networks

超密集异构网络是5G大幅提升单位面积的频谱效率、成倍增加网络容量的重要途径。由于网络的异构化以及5G工作频段向更高频带拓展,上行受限问题凸显,亟需制定切实可行的上行性能提升方案。通过对辅助上行、双连接以及上下行解耦方案的分析,提出了在5G超密集异构网络不同建设阶段的上行增强解决方案。

Ultra-dense heterogeneous networks （Ud-HetNets） have been recognized as an important way to significantly improve the spectrum efficiency per area and multiply the wireless capacity of 5G. However, due to the heterogeneity of cellular networks and the expansion to higher work frequency for 5G, the problem of limited uplink is more obvious than ever before. Therefore, the practicable uplink performance improvement schemes are necessary. By analyzing the supplementary uplink, dual connectivity, downlink and uplink decoupling, an uplink performance improvement scheme for different construction stages of 5G Ud-HetNets is proposed.
