Coexistence Analysis of 10-10.5 GHz IMT and EESS (passive) Systems

With the commercialization of International Mobile Telecommunications (IMT) technology, this paper studies the problem of ensuring coexistence between new frequency bands and existing satellite systems, which has led to an increasing demand for spectrum resources. Specifically, the research evaluates the potential interference between IMT and Earth-Exploration Satellite Service (passive)-EESS (passive) in the 10-10.5 GHz frequency band. This paper presents an innovative methodology for constructing a dynamic EESS (passive) system model based on orbital elements. In addition, the IMT system model was built by analyzing satellite imagery data. The results show different levels of interference sensitivity among passive sensors, highlighting the need to impose necessary restrictions on IMT systems to protect EESS (passive) systems. Overall, this paper introduces an innovative method for modeling the dynamic interaction between satellites and large-scale base stations, which is beneficial for analyzing the coexistence of IMT and EESS (passive) systems.
