Analysis of Propagation Models for Frequency Coordination Between 5G Base Stations and Satellite Earth Stations at FR1

The deployment of 5G Time Division Duplex (TDD) technology in the 3.6GHz band has revealed novel challenges in the field of interference management w.r.t sharing the spectrum with other radio services in the same or adjacent bands. In order to protect the potential interference victims, propagation models are applied to predict the expected harmful interference in the regulatory process. In such a regulatory process the use widely agreed models usually based on ITU-R recommendations is common practice. In this paper measurements of the received interference at a high-sensitive satellite earth station originating from a 5G base station mimicked by a drone has been used to analyse four propagation models at the 5G Frequency Range 1 (FR1).
