Study Of Compatibility Between 26 GHz Large-Scale IMT System And Inter-Satellite Services

The International Telecommunication Union has set up research for the 5G high frequency band,which is intended to explore new available spectrum resources for the future 5G system.At present,the 26 GHz band is one of the preferred hot bands in the world.This paper focuses on the characteristics of International Mobile Telecommunications(IMT)system and inter-satellite service in the 26 GHz band,analyzes parameters and models,and performs modeling and simulation of inter-system compatible coexistence research.The main works of this paper can be summarized as follows.First,the planning dynamics of inter-satellite service in the 26 GHz band and the interference scenarios of IMT system to inter-satellite service are analyzed.The related models for Large-Scale IMT system compatible coexistence research are studied.Second,based on the base station modeling method based on the visible area of the satellite,the large-scale IMT system interference satellite constellation is simulated,and the obtained uplink interference and uplink and downlink combined interference results are statistically and comparatively analyzed.Third,based on Visualyse platform,system-level modeling of large-scale IMT systems and inter-satellite service systems is carried out,and the scenarios of IMT system interference satellite systems deployed in China and surrounding areas and globally are simulated dynamically,and the results are summarized and analyzed.Based on the current situation of 26 GHz frequency band planning in China,this paper selects a reasonable analysis model,builds a system-level simulation that meets the requirements of international standards,and finally completes the compatible coexistence analysis of large-scale IMT systems and inter-satellite services in the 26 GHz band,which provides very useful information for engineering applications.
