Handling the 30-50ms RTT of satellite channels without stalling TCP or dropping user plane throughput.
Deploying harq over satellite channels in non-terrestrial environments requires solving fundamental physics constraints: path loss over 1000km distances, rapid carrier frequency shifts due to Doppler effects, and power-thermal limits of spaceborne hardware. The architecture provides deterministic mitigation strategies.
The protocol workflow for harq over satellite channels coordinates physical layer signal acquisition with higher-layer transport resilience. By leveraging open-loop ephemeris calculations and adaptive retransmission timers, communication links maintain uninterrupted throughput across satellite handoffs.
