METHOD FOR TRANSMITTING BA,DWARD TRAFFIC DATA ACCORDIG TO BACKWARD CHANNEL ALLOCATION

摘要

PURPOSE: A method for transmitting reverse traffic data according to the allocation of a reverse channel is provided to allocate a dedicated pilot channel or a pre-pilot channel, and to obtain reverse synchronization through the allocated channel, so as to stably transceive reverse traffic data. CONSTITUTION: Pre-pilot channel of each user are set to be longer than one slot(121). Traffic channel for transmission of the user are aligned in corresponding slots(122). Pilot channels for transmission of each user are opened earlier than the traffic channels, to adjust reverse synchronization with enough time(123). The aligned corresponding traffic channels of each user are opened, to transmit traffic data by the unit of packet(124). Whether traffic data of each user are all transmitted is decided(125). If traffic data are not transmitted entirely, the 123-step is returned. And if traffic data of each user are all transmitted, the steps are ended.
