NTN and 6G: Networks in Revolution – Insights from the EuCNC Workshop in Poznań”

A workshop entitled “System Level Analysis of Non-Terrestrial Networks” was organized by the center in Poznan on June 3.

It was based on the general fact that 6G will feature the integration of
2D cellular networks and 2D or 3D NTN networks.
The latter comprise UAV networks, LEO constellations or LEO, MEO and GEO
constellations. The former will comprise several
types of cellular organizations.  NTNs already constitute one of the most
creative domains of communication networks
research and engineering worldwide, in a broad set of domains including
data communications, data sensing and harvesting,
or Internet routing. There is a clear need for a system level analysis of
3D NTN networks which would extend the 2D
framework and even more for an analysis methodology of the network of
networks sharing all the same frequency and
spatial resources. This is already clear when one tries to assess the
impact of NTN on 2D networks.
This is also the case when one wants to assess the potential gains of an
organized interplay. This workshop was then
focused on the system level analysis of such networks. The aims of the
presentations were the evaluation and the
prediction of the statistical properties of spectral efficiency in such
networks, the design of new tools for the
identification of optimal architectures, and the economic analysis of such
networks.
The topics covered multi-tier networks, routing in NTN, RISs and NTN,
Doppler shift analysis, Handover analysis,
and a variety of scheduling issues. There were several talks by members of
the center
(including one by P. Martins and A. Balakrishnan, and one by F. Baccelli
and S.K. Jhawhar).
There were talks by researchers from Finland, France, Ireland, Italy,
Poland, and South Korea.

The workshop was also linked to SNS INSTINCT, to the BPI-IMT project 5GMmW
with Constellations Technologies,
Greenerwave and Onera, and to a STAR Hubert Curien project between France
and in South Korea
