摘　　要：移动通信是一个资源受限性系统,而频谱是非常关键的资源和要素。目前,移动通信已经进入5G时代,而5G的主力频谱是3.5 GHz,频率越高,覆盖能力就越弱,因此其很难实现城区的深度覆盖及农村的广覆盖,且实现的建设成本也会非常高。目前,中低频谱资源几乎被3/4G占据,且无法全部重耕这些优质的低频段资源。5G与3/4G共用中低频段,由于每张网络承载用户是一个动态变化的过程,若采用固定分配频谱的策略,则会出现网络忙闲不均的现象,从而不能完全发挥中低频谱的利用率。动态频谱共享技术可有效解决上述问题,提高频谱利用率。文中在介绍技术原理的前提下,对该技术实现方式以及部署方式进行了介绍,最后通过测试数据证明了该技术的有效性。Mobile communication is a resource constrained system,and spectrum is a crucial resource and element.At present,mobile communication has entered the 5G era,and the main spectrum of 5G is 3.5 GHz.The higher the frequency,the weaker the coverage ability,making it difficult to achieve deep coverage in urban areas and wide coverage in rural areas,and the construction cost will also be very high.At present,the mid to low frequency spectrum resources are almost occupied by 3/4G,and it is not possible to fully cultivate these high-quality low-frequency resources.5G and 3/4G share the mid to low frequency bands.As each network carries users in a dynamic process,if a fixed spectrum allocation strategy is adopted,there will be uneven network busy and idle,which will not fully utilize the utilization of mid to low frequency bands.Dynamic spectrum sharing technology can effectively solve the above problems and improve spectrum utilization.On the premise of introducing the technical principles,this paper introduces the implementation and deployment methods of the technology,and finally proves the effectiveness of the technology through test data.
