Abstract： 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.
