NTN HARQ Redundancy Bundling for Delay-Tolerant Retransmission

The patent applies preliminary action by pre-configuring multiple HARQ processes (e.g., 8 or 16 processes) before communication begins. Each process is pre-allocated with specific timing parameters and resource configurations, allowing the system to immediately switch to an available process when a retransmission is needed, rather than waiting for the standard HARQ timeline to expire. This pre-preparation of multiple parallel channels resolves the contradiction by maintaining reliability through ready-to-use retransmission paths while minimizing latency through immediate process switching.

The patent implements periodic action by transmitting channel feedback at optimized intervals rather than continuously or at every transmission opportunity. The feedback periodicity is specifically adapted to the NTN propagation delay characteristics, creating a rhythm that balances information freshness with resource conservation. This periodic feedback mechanism resolves the contradiction by providing sufficiently accurate channel state information at strategically timed intervals while significantly reducing the energy and resource overhead associated with frequent feedback transmissions in high-latency NTN environments.
