Abstract
A communication system dispatches packet data (130) from a master transceiver (10) to a slave transceiver (20). A slave transceiver (20) records the successful arrival of the data packet (130) in an acknowledgment history (115). When propagation conditions between a slave transceiver (20) and a master transceiver (10) are non-ideal, an acknowledgment (140) may be lost and needless retransmission of data packet (130) commenced. However, a slave transceiver (20) generates an acknowledgment (140) from an acknowledgment history (115) containing confirmations for multiple data packets contained within an outstanding packet window (120). If a specific acknowledgment (140) does not arrive at a master transceiver (10), a subsequent acknowledgment (140) contains confirmation of a previously received data packet (130) thus avoiding the needless retransmission of a previously successfully received data packet (130).
