Final Report on NTN System Level Simulations

August 1, 2024

The final report on “NTN System Level Simulations“ provides a comprehensive summary of the evaluation work conducted on the coexistence of terrestrial and non-terrestrial gNBs within the NTN System Level Simulator. Scenarios featuring flying gNBs at varying altitudes, as well as mobile users situated on the ground or in the air, were defined for this purpose. The necessary parameter configurations for initializing these scenarios—including satellite payload, user terminal, channel model, and traffic model properties—were established. The report also includes a list of key performance indicators, such as SNR and throughput, which are utilized to analyze the evaluated scenarios based on specific parameter configurations.

Furthermore, the report outlines the handover process between two non-terrestrial gNBs and highlights other features that will be developed throughout the project. The role of artificial intelligence (AI) in a 6G system is also explored in this context.

Combined Airspace and NTN Networks: Use Cases, Scenarios, and Regulations

September 26, 2023

This report is intended for those readers that have an interest to get an overall view and understanding of combined Airspace and NTN networks (combined ASN networks).

The main benefits are that the Combined Airspace and NTN use cases, scenarios and regulations provide an overall framework of descriptions and analysis for combined ASN networks including a definition of holistic aerial networks, an identification and analysis of international programs for Innovating the Digital European Airspace and beyond, 6G regulations and spectrum for combined ASN networks, 6G use case segments for digital airspace and NTN, highlighted 6G-SKY use cases, 6G-SKY demo use cases, and a combined ASN networks impact on sustainability. This material can be further used to trigger research investigations and commercial actions for the readers of this report.

Holistic Adaptive Combined Airspace and NTN networks Architecture for 6G

April 30, 2023

This report aims to provide the reader with the initial design considerations of architectures for the combined airspace and NTN networks (combined ASN networks) with a focus on low altitude aerial platforms including airplanes as users.

This project report first discusses the primary principles for the design of combined ASN network architectures. These principles for the holistic adaptive 6G-SKY network architecture require new functional views to assure three-dimensional (3D) service requirements via network functions such as 3D end-to-end (E2E) and domain-oriented network orchestration and slicing. Other dimensions shaping the 6G-SKY network architecture are the EU aviation strategy with EU Single European Sky (SES) and Single European Sky ATM Research (SESAR) initiatives and requirements from urban air mobility and advanced air mobility. The report discusses design aspects of the ASN architecture to enable efficient network management and control of the multi-layered architecture.
