The main theme of the document concerns the coexistence of satellites and future terrestrial networks, including the current state of technologies and open issues.
The document covers aspects such as interference analysis, resource allocation, optimization frameworks, interference management, channel capacity, and failure probabilities. Challenges such as the coexistence of backbone and access networks, resource coordination, channel modeling, and algorithmic complexity are discussed. Prospects include cognitive radio systems, integration with new systems like reconfigurable intelligent surfaces, and quantum communication technologies.
