Spectrum Sharing Technology for Satellite-Terrestrial Integrated Networks Towards 6G
Satellite network has been widely recognized as an indispensable part of the next-generation mobile communication system,which together with the existing terrestrial cellular network can provide ubiquitous and wideband access service for massive users world-wide by taking the advantages of each to form satellite-terrestrial integrated network.How to efficiently share the limited spectrum re-sources between the two networks and mitigate coexistent interference has become one of the current technical difficulties and hot topics.The typical types of interference existing in the spectrum sharing of satellite-terrestrial integrated network are analyzed,and the inter-system interference is simulated.The potential key technologies for spectrum sharing in the satellite-terrestrial integrated network are ana-lyzed,and the challenges of spectrum sharing in the satellite-terrestrial integrated network are summarized.
