| 摘 要： | 3.5 GHz频段是目前全球5G部署的主流频段,也是国内两大运营商的主要部署频段,它具有带宽大、传播损耗高、穿透性能差等特点。2.1 GHz NR是运营商最早可重耕的低频FDD频段,可弥补3.5 GHz频段上行覆盖的不足,但在容量方面存在短板,与3.5 GHz NR差距比较大。因此,要综合2个频段各自的优点,合理利用下行载波聚合,打造高低频协同的5G网络。

| Abstract: | 3.5 GHz frequency band is currently the mainstream frequency band for global 5G deployment,and it is also the main deployment frequency band for the two major domestic operators.It has the characteristics of large bandwidth,high propagation loss and penetration.2.1 GHz NR is the earliest re-farming FDD low frequency band.It can make up for the shortcomings of 3.5 GHz in uplink coverage,but there is a short board in capacity,which is lower than 3.5 GHz NR.Therefore,it is necessary to synthesize the advantages of the two frequency bands,and make reasonable use of downlink carrier aggregation to create a high and low frequency cooperative 5G network. |
