Dynamic Fencing for Interference Mitigation in Integrated Satellite-Terrestrial Networks

Integrated Satellite-Terrestrial Network (ISTN) is one of the promising approaches for global wireless connection in 5th Generation (5G) and beyond networks. The integration of terrestrial and non-terrestrial networks open a wide range of opportunities in the networking domain. Though the integrated system has numerous benefits, it also has various challenges including the interference caused by the different networks, (satellite and terrestrial) sharing the same frequency band. The interference between both the networks degrades the performance of integrated network communication systems. This paper presents a scenario for integrated satellite and terrestrial networks (ISTN) and proposes a novel solution for interference management by coordinating satellite and terrestrial networks in order to minimize interference and enhance the overall throughput of the integrated network. To address this issue, a dynamic fencing mechanism is applied where a fence is created for a time slot to provide fairness to the victim users getting affected by the severe interference.
