Here, we consider the constraint condition to simplify the problem while minimizing interference, as motivated by [8]. The bandwidth constraints must be properly set to minimize interference.…”

“…It is regarded that among the major challenges facing the use of an ATC with an MSS is the problem of interference; thus, an interference mitigation scheme using ground-based beamforming was proposed. In addition, the authors in [8] proposed the use of a radio resource management strategy in which the optimal constraint conditions are applied to minimize inter-beam interference for multiple beams based on satellite networks. In particular, an optimum frequency bandwidth and satellite transmission power scheme was proposed in [8] to deal with the ever-changing user distribution and inter-beam interference conditions.…”

An integrated multi‐beam satellite and multi‐cell terrestrial system is an attractive means for highly efficient communication due to the fact that the two components (satellite and terrestrial) make the most of each other's resources. In this paper, a terrestrial component reuses a satellite's resources under the control of the satellite's network management system. This allows the resource allocation for the satellite and terrestrial components to be coordinated to optimize spectral efficiency and increase overall system capacity. In such a system, the satellite resources reused in the terrestrial component may bring about severe interference, which is one of the main factors affecting system capacity. Under this consideration, the objective of this paper is to achieve an optimized resource allocation in both components in such a way as to minimize any resulting inter‐component interference. The objective of the proposed scheme is to mitigate this inter‐component interference by optimizing the total transmission power — the result of which can lead to an increase in capacity. The simulation results in this paper illustrate that the proposed scheme affords a more energy‐efficient system to be implemented, compared to a conventional power management scheme, by allocating the bandwidth uniformly regardless of the amount of interference or traffic demand.

“…Thus, satellite does not have sufficient flexibility to satisfy the traffic requests on a beam. When an unpredictable event, such as a disaster, regional warfare and deteriorating weather conditions, occur in a special spot beam, it is important to ensure a new connection to the satellite channel [2] [3]. However, if many terminals require access to the special beam channel, the speci2l beam channel will be saturated and new connection request will be blocked, while adjacent beam channel resource is available.…”
