Modeling Method for Interference Analysis between IMT-2020 and Satellite in the mmWave Band

We propose a modeling method to calculate the interference that existing satellite services receive from fifth-generation mobile communication systems (IMT-2020). This study is based on the modeling and parameter document proposed for spectrum sharing research provided in the ITU- recommendation for IMT-2020 services in the millimeter-wave band. To complement previous research, we expand the coverage area from the footprint area to entire area by considering side lobe of satellites. In addition, we obtain various results depending on the location and main lobe direction of the satellite by using terrain data. Furthermore, we use this modeling method to calculate the interference that the Fixed-Satellite Service (FSS) satellite and Earth Exploration- Satellite Service (EESS) passive sensor receive in the co-channel and adjacent channel and compare that with protection criteria to present the possibility of frequency coexistence.
