Satellite-enabled 5G services have the potential to provide worldwide connectivity. In this paper, we give an introduction on the roadmap in 3GPP standardization of 5G as
well as on the enhancements to support non-terrestrial networks (NTN) in Release 17. We further provide first over-the-air test results of a successfully demonstrated extension of 5G New Radio (NR) to support non-terrestrial networks (NTN). As an proof of
concept, we tested some of the planned extensions for 5G NR for NTN via a geostationary satellite. The 5G base station as well as the 5G user equipment utilized in our experiments were fully software-defined solutions. Both components were based on OpenAirInterface (OAI), an open-source implementation of the 5G New Radio protocol stack, which runs on general purpose platforms.
