摘　　要：与4G工作频段相比,5G的工作频段更高,频段的传播损耗和穿透损耗更大,其覆盖将面临严峻的挑战。首先,简述国外和国内5G频段分配现状;其次,基于5G频段UMa传播模型、RMa传播模型,通过仿真分析两种传播模型在城区和农村场景下5G的覆盖性能;最后结合链路预算表及传播模型,得出5G覆盖性能的结论。Compared with 4G operating frequency band, 5G has higher operating frequency band, leading to higher propagation and penetration loss, and its coverage will face severe challenges. Firstly, the current situations of foreign and domestic 5G frequency band allocation are briefly described. Secondly, based on the UMa propagation model and RMa propagation model of 5G frequency band, the 5G coverage performance in urban and rural scenarios of the two propagation models is obtained through simulation analysis. Finally, combining with the link budget table and the propagation model, the conclusion of 5G coverage performance is obtained.
