METHOD AND DEVICE FOR DYNAMICALLY CHANGING PREAMBLE DURATION

摘要

A method (200) and device dynamically changes preamble duration of a message. A message (202) is transmitted over a forward channel to a target device, wherein the message includes a preamble (208) of a predetermined time duration. A reverse channel is monitored (216) for a confirmation message from the target device. The transmission of the preamble is stopped (220) before expiration of the predetermined time duration upon receiving the confirmation message over the reverse channel.
