Abstract

The ASCENT project studies spectrum sharing between
satellite and cellular networks using a Licensed Shared
Access (LSA) approach, in which information stored in a
database is exploited to enable spectrum sharing between
users. The project focuses on one side 5G pioneer bands 3.4-
3.8 GHz and 24.25-27.5 GHz, which are well-recognised as
satellite frequency bands, and on the other side on legacy
IMT frequency bands. We identified different spectrum
sharing scenarios and defined four use cases. We have
developed an LSA system testbed, which is used to study and
validate the interest of the LSA approach in
satellite/terrestrial sharing scenarios.
The results of our simulations and the tests realized on the
testbed show that the LSA approach could be used to
improve spectrum sharing between satellite and terrestrial
networks. This approach could be envisaged to facilitate
spectrum sharing between terrestrial mobile network such as
International Mobile Telecommunications (IMT) and satellite
networks operating in a same frequency band. Such an
approach could offer new spectrum sharing opportunities
which could benefit to both mobile and satellite community.
The LSA testbed and the results of the project will be further
utilized to develop and assess new sharing scenarios that
could lead to creating new spectrum opportunities for
different radiocommunication systems.
