In this paper, we propose an efficient resource allocation scheme for an integrated satellite/terrestrial network. The proposed scheme is a frequency sharing technique to mitigate its inter-component interferences which can be generated between the satellite beam and terrestrial cells that are operated in the same frequency. The proposed dynamic resource allocation scheme can mitigate the total inter-component interference by optimizing the total transmission power, which can lead to an increase in capacity. In such a system, the interference situation can be different by the distributed traffic demands or up/down link communication environments. In this point of view, we evaluate the performance of the proposed scheme by analyzing the total consumed power as well as the amount of interference under the different traffic distributions and interference environments.
