Abstract
A wireless access node to improve data transmission throughput comprises a wireless communication transceiver and a processing system. The wireless access node transmits a first data packet comprising a preamble for delivery to a wireless communication device during a first timeslot, monitors for a response transmitted from the wireless communication device during a predetermined number of timeslots, and if the response transmitted from the wireless communication device is not received during the predetermined number of timeslots, modify the preamble to generate a modified preamble, retransmit the first data packet with the modified preamble for delivery to the wireless communication device during a second timeslot, and if an acknowledgement of receipt of the first data packet with the modified preamble is received from the wireless communication device during the predetermined number of timeslots, transmit a second data packet for delivery to the wireless communication device during a third timeslot.
