Analysis of Spectrum Sharing in Hybrid Satellite-Terrestrial Networks

Abstract

With the trend of integrally developing satellite communication networks and terrestrial mobile communication networks becoming more and more prevalent, hybrid satellite-terrestrial networks (HSTN) is gradually regarded as the basic expectation framework of the sixth-generation mobile communication technology. However, since frequency band resources are limited, the explosive growth of communication device and traffic data has led the frequency band resources that can be exploited and utilized by existing technologies to become increasingly scarce, which will restrict the development of HSTN as a key bottleneck. To break this development obstacle for HSTN, achieving spectrum sharing technology between satellite and terrestrial networks has become a desirable technical measure. In this paper, we study the problem of spectrum sharing in hybrid satellite-terrestrial networks, and different spectrum sharing scenarios and radio resource coordination technologies are introduced. The performance of these models related to different techniques scheme is then presented.
