  Abstract

Multi-beam satellite systems enable efficient utilization of frequency resources by virtue of dynamic resource allocations. Integrated satellite and terrestrial networks with a frequency reusing scheme can be an effective means to provide mobile satellite services. In such a network, there will be harmful interferences between the satellite beam and terrestrial cells using the same frequency band, via the frequency reusing scheme. Since the bandwidth and power resources of a satellite system is very scarce and limited, special attention should be paid on the resource allocation considering the interference conditions. This paper first introduces the basic concept and operational principle of the resource allocation scheme under this kind of interference limited situation. In addition, we present interference modeling between satellite beams and terrestrial cells, and illustrate the effect of the interferences on the resource allocation by using mathematical equations. By this way, theoretical analysis of the resource allocation algorithm can be provided. Finally, this paper provides extensive simulation results under various interference conditions according to frequency reusing factors, so that the results can be utilized during the practical system engineering process
