ABSTRACT:
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.
