A Study on the Coexistence of TD-LTE/5G and Mobile Satellite Service

Abstract

With the continuous development of emerging information technologies, the preciousness and scarcity of wireless spectrum resources are becoming increasingly prominent. With the rapid development of wireless mobile communications, Long Term Evolution (LTE) system is actively studied and widely deployed. Meanwhile, the satellite communication system is also one of the research hotspots in recent years. The compatibility analysis of the two systems in the adjacent frequency and the same frequency has far-reaching significance. In this paper, we study the coexistence of TD-LTE system and mobile satellite services (MSS). By the deterministic analysis based on the link budget criteria, the coexistence conditions between TD-LTE and the typical MSS system in the worst case are studied. In addition, the system-level simulation based on Monte Carlo is used to study the interference coexistence between the two systems in different scenarios. For the analysis results, the conditions for coexistence of the TD-LTE system and the typical MSS system are given and practical suggestions are made. Finally, some issues that need to be considered in the coexistence problem between 5G and the typical mobile satellite service system, as well as preliminary assessments, are proposed.
