Patent ID: 8565126

Claim:
A method in a transceiver of a telecommunications system wherein protocol data units (PDUs), are exchanged between the transceiver and another transceiver, each PDU being identified by a PDU sequence number, said method comprising: receiving a status report from the other transceiver, said report comprising, for each negatively acknowledged (NACKed) PDU, a corresponding NACKed PDU sequence number and further comprising, for each acknowledged (ACKed) PDU, a corresponding ACKed PDU sequence number; comparing each NACKed PDU sequence number indicated in the status report with previously acquired ACKed PDU sequence numbers from at least one previous status report; and while continuing to process additional status reports received from the other transceiver and without halting any pending PDU transmissions to the other transceiver: preventing retransmission of each NACKed PDU having a NACKed PDU sequence number that has already been ACKed in a previous status report; and discarding said status report if it comprises at least one NACKed PDU sequence number that has already been ACKed in a previous status report.
