Abstract
Simultaneous frequency sharing in integrated satellite and terrestrial networks can help to achieve increased network capacity based on an efficient reuse of frequency resources in a way that minimizes interference. In this paper, we investigate the use of the 2GHz MSS frequency allocation for satellite and terrestrial mobile services based on LTE. Results show that uplink frequency sharing is not feasible due to the predominant terrestrial interference into the satellite service. On the other hand, downlink frequency sharing is feasible for pedestrian microcells and vehicular macrocells but not for the wider rural cells. In this regard, a satellite multimedia broadcast service can be deployed simultaneously with twoway terrestrial mobile service in urban and suburban areas. Furthermore, dynamic radio resource allocation combined with interference coordination can be used to optimize performance throughout the integrated network.
