The reuse of hybrid automatic repeat request (HARQ) process identifiers (IDs) is enabled under controlled conditions. Consequently, certain delays may be reduced, including those delays that may be associated with waiting for a process ID to be released. A user equipment (UE) may initiate new transmissions sooner than would be allowed according to existing mechanisms. The sooner transmissions may be particularly convenient in those situations wherein previous data has been successfully delivered. Network resources may, as a consequence, be use more efficiently in time-sensitive communication scenarios. An adaptable feedback process, from satellite to UE, is also enabled, which provides the satellite with a flexibility to adjust to different latency and resource constraints, thereby improving overall communication robustness. The flexibility is particularly beneficial in NTNs with higher propagation delays.
