VERWENDUNG DES FP-KOPFTEILS, UM DER RNC ZU SIGNALISIEREN, DASS KNOTEN B DIE ANZAHL DER NEUÜBERTRAGUNGEN NICHT BESTIMMEN KONNTE

摘要

The FP header is used to signal the RNC that the Node B has not been able to determine or has not been able to accurately determine the number of retransmissions. A first embodiment is to reserve a bit pattern for use in the‘Number of HARQ retransmissions’field on the Iub frame protocol DATA FRAME header to indicate that Node B does not know the actual number of retransmissions. A second embodiment is to define a one bit flag on Iub/Iur FP DATA FRAME header to indicate that the value set in the“Number of HARQ Retransmissions”in the FP header is an estimated/guessed value by Node B or not.
