Abstract:
A method for receiving data frames in a transceiver, said method comprising the steps of:detecting that a first selected frame has not been received in a sequence of a first plurality of frames transmitted to the transceiver;transmitting a retransmission request from the transceiver, said retransmission request requesting retransmission of said first selected frame to the transceiver;starting a timer in response to transmitting said retransmission request;receiving a second plurality of frames at the transceiver and buffering said second plurality of frames in a buffer;setting a pointer that indicates the highest sequence number of frames in said buffer received as a result of retransmission requests other than said retransmission request requesting retransmission of said first selected frame;receiving a second selected frame at the transceiver subsequent to receiving said second plurality of frames, placing said second selected frame in said buffer, incrementing said timer and updating said pointer; anddetermining whether an expiration action should be taken on said timer based on said pointer.
