摘　　要：动态频谱共享(Dynamic Spectrum Sharing,DSS)技术在同一频段内为不同制式的通信技术动态、灵活地分配频谱资源,这种技术在快速部署5G网络、实现4G向5G平滑演进、利用低频段实现5G网络广覆盖等方面具有重要意义。虽然DSS在多数情况下通过灵活分配频谱资源可以提高频谱资源利用率,但引入DSS技术的同时,也带来了额外的频谱开销。介绍了目前主流的DSS技术方案与相应的开销计算方法,通过对比引入DSS技术前后的开销损失来分析各种DSS技术方案的优缺点,总结归纳出主流技术方案的额外开销。Dynamic spectrum sharing(DSS)technology allocates spectrum resources dynamically and flexibly for different communication technologies in the same frequency band.This technology is of great significance in the rapid deployment of 5G network to realize the smooth evolution from 4G to 5G,and the realization of 5G network wide coverage by using low frequency band.Although DSS can improve the utilization of spectrum resources by flexibly allocating spectrum resources in most cases,the introduction of DSS technology also brings additional spectrum cost.This paper will introduce the current mainstream DSS technology scheme and the corresponding cost calculation method,and analyze the advantages and disadvantages of various DSS technology schemes by comparing the cost loss before and after the introduction of DSS technology.
