Radio Resource Management for Hybrid Satellite-Terrestrial Network

Hybrid satellite-terrestrial networks demand proficient coordination of Radio Resource Management (RRM). Together, these networks offer the best of both satellite and terrestrial communicative technologies for fast and widespread connectivity. However, it is a difficult task to manage the limited radio resources involved in this very heterogeneous environment. The main goal of RRM in hybrid satellite-terrestrial networks is to provide efficient resource utilization and quality of service support for different applications. They touch on areas such as interference management, spectrum sharing, handover between satellite links, and offloading to terrestrial networks. In order to make RRM more efficient, the following techniques are used during resource allocation: adaptive modulation and coding (AMC), dynamic scheduling, and power control. Such techniques exploit network topology, propagation conditions, and user location to increase spectral efficiency and reduce interference.
