Patent ID: 7065051

Claim:
A method for wirelessly transmitting data between a plurality of subscriber units and a base transceiver station, the method comprising: at least one subscriber unit transmitting a request to send data blocks to the base transceiver station, the request including a data transmission queue size value; updating at the base transceiver station, a base user queue size estimate that corresponds to the one subscriber unit that transmitted the request to send data, the base user queue size estimate being based upon the data transmission queue size value; the base transceiver station generating a schedule that includes time slots and frequency blocks in which the requested data blocks are to be transmitted from the one subscriber unit to the base transceiver station; the at least one subscriber unit transmitting the data blocks the at least one subscriber unit requested to send according to the schedule, each transmitted data block comprising encoded information representing a current data transmission queue size value; updating the base user queue size estimate based upon the encoded information; and the base user queue size estimate influencing future schedules generated by the base transceiver station.
