A study of LTE uplink resource allocation with long delay environment for satellite-airplane communication

抄録

Unlike terrestrial radio communication, airborne Internet access services are still based on satellite communication systems, which use single carrier FDMA/TDMA access interfaces. To maximize the resource utilization and acquire maximum benefit of the services, it would be natural to apply OFDMA/SCFDMA based terrestrial systems like LTE for the satellite-airborne communication systems. However, these systems were originally designed for short delay conditions in microseconds and have difficulties under the very long delay between satellite and airplanes. In this paper, we propose a simple and effective way of resource allocation for LTE uplink SCFDMA which would be applicable to airborne-satellite communication systems.
