Interference Assessment for the Spectrum Sharing Between IMT-2020 and Inter-satellite Service

This paper analyzes interference coexistence of IMT-2020 (International Mobile Telecommunications-2020) and inter-satellite service where both systems operate in the same spectrum band of 25.25–27.5 GHz. This work can be regarded as a good reference to the research community, industry and regulators which are currently investigating spectrum requirements and technology options for 5G system. Considering the interference scenario between the return inter-orbit link of data relay satellite system and downlink of IMT-2020, we adopt realistic system parameters and radiation pattern, combined with very recent channel from the literature. Simulation results indicate that the interference from IMT-2020 downlink to Data Relay Satellite (DRS) is above the interference level while the LEO spacecraft cause acceptable interference to IMT-2020 downlink.
