Query: Integrated Communication and Navigation for Ultra-Dense LEO Satellite
  Networks: Vision, Challenges and Solutions   Next generation beyond 5G networks are expected to provide both Terabits per
second data rate communication services and centimeter-level accuracy
localization services in an efficient, seamless and cost-effective manner.
However, most of the current communication and localization systems are
separately designed, leading to an under-utilization of radio resources and
network performance degradation. In this paper, we propose an integrated
communication and navigation (ICAN) framework to fully unleash the potential of
ultra-dense LEO satellite networks for optimal provisioning of differentiated
services. The specific benefits, feasibility analysis and challenges for ICAN
enabled satellite system are explicitly discussed. In particular, a novel beam
hopping based ICAN satellite system solution is devised to adaptively tune the
network beam layout for dual functional communication and positioning purposes.
Furthermore, a thorough experimental platform is built following the Third
Generation Partnership Project (3GPP) defined non-terrestrial network
simulation parameters to validate the performance gain of the ICAN satellite
system
