1. A transmitting apparatus comprising:

  • a radio link control (RLC) device configured to produce a RLC data protocol data unit (PDU) from data;

    a medium access control (MAC) device configured to process the RLC data PDU to produce a MAC PDU for transmission as a data block using hybrid automatic repeat request (HARQ);

    wherein the RLC device is further configured to receive an indication that the RLC data PDU was not successfully received; and

    wherein on a condition that the RLC data PDU was not successfully received;

    the RLC device is configured to retransmit the RLC data PDU and to prioritize the retransmitted RLC data PDU over non-retransmitted RLC data PDUs; and

    the RLC device is further configured to determine a number of times that the RLC data PDU was transmitted/retransmitted.
