Integrating the satellite network with a 5G network to equip the latter with worldwide coverage and high availability is an innovative and interesting idea, however, due to the large distance of the physical link between the two networks, which is in order of hundreds or thousands of kilometers, the communications conducted over this link may not be reliable. Depending on link adaptation is a good idea to increase the link reliability and better exploit the wireless communications channel, but, in this particular link, the adaptation process alone is not enough since the channel information reported to the transmitter is outdated (the channel changes much faster than the round trip time (RTT) of the non−terrestrial system.
