| Abstract(in English) | We are focusing on the provision of communication areas from the sky by satellites and High-Altitude Platform Stations (HAPSs) to realize extreme coverage extension.For direct communication between HAPS and terminals, the use of the same frequency band as the terrestrial system, including the 2-GHz band, has been identified.Therefore, when the HAPS system is applied on top of the ground area, inter-system interference avoidance is essential.In this paper, we assume two types of inter-system interference avoidance techniques, using several frequenciey modes and the 3D cell control technique proposed by the authors.We evaluate the system performance when the interference avoidance techniques are applied using a system-level simulator assuming an actual ground system.The evaluation results show that the interference reduction effect could be obtained in both HAPS and ground system by the application of the interference avoidance techniques. |
