A method includes sending to a receiving device from a transmitting device
a Radio Link Control (RLC) re-transmission scheme selected from a
plurality of RLC re-transmission schemes, and using the selected and sent
scheme at least at one of the receiving device and the transmitting
device. In another exemplary non-limiting embodiment the method includes
detecting, at the receiver, a gap in RLC Protocol Data Unit (PDU)
sequence numbers, associating a timer with the gap, and starting the
timer when the gap is detected. In still another exemplary non-limiting
embodiment, the method includes detecting a gap in a RLC PDU sequence,
monitoring a HARQ channel for a period of time to determine if a
predetermined bit has changed, and determining if a transmission is lost.
