From the beginning, 3GPPs vision of ubiquitous communication included the usage of satellite or airborne based network components.
Heading towards 6G we envision the contribution of NTN into the 6G system, IMT-2030 sets some clear requirements incorporating a non-terrestrial, unified network architecture from its inception. Release 17 considered as the start of NTN in 5G targets at enabling non-terrestrial network services. Later releases will enhance the NTN contribution and even if 6G may be an evolution and not a revolution, NTN will play a pivotal role from the advent of 6G.
This presentation will outline the technology evolution from the first NTN up to the anticipated technology evolutions on the path to 6G. The NTN technology starts with transparent mode architecture, incorporates regenerative mode and multi-connectivity mobility scenarios on a mid-term basis, and then looks towards long-term aspects like 3D unified and resilient networks, ultimately paving the way towards “beyond cellular” in a 6G network that includes NTN from its inception.
In addition, we would like to present the evolution of Test and Measurement aspects and how T&M can ensure the successful operation and development of future NTN networks.
