  • the high latency in the air interface described in Section 2 has become a problem for the management of the HARQ. With such high latency, it is possible that all the HARQ processes available in the transmitter are used before the first ACK/NACK is received, assuming that one process can be used at every TTI or every few TTIs (one TTI corresponds to 0.25 to 1ms, depending on the subcarrier spacing).
  • the HARQ process ID used for the next transmission shall reuse one of the HARQ process IDs, who have not yet been terminated by an ACK. In the UE side, this will cause confusion about how to decide whether the process ID represents a HARQ retransmission or a new transmission reusing the same ID.

  • Satellite networks are expected to cover very large areas, with cell ranges that can go above 500 km and they have limited link budget due to the very large distances between users and satellites.
