1. A method for improving throughput in a wireless communication network that includes a base unit, a plurality of remote units, a reverse channel for communicating to the base unit and a forward channel for communicating from the base unit, the method comprising the steps of:

  • at a first remote unit, transmitting a first portion of a first data package in a time slot on the reverse channel;

    during a round trip time interval, detecting whether any other remote units have successfully transmitted a time slot of data to said base unit, the round trip time interval including a plurality of time slots;

    determining from said detecting step a queuing position, the queuing position decreasing in relation to the number of other remote units that successfully transmitted to the base unit before the first remote unit as detected during the round trip interval associated with the first remote unit'"'"'s said portion of first data package, for transmitting additional portions of said first data package on the reverse channel;

    updating said queuing position based on information received on said forward channel; and

    transmitting additional portions of said first data package in a plurality of time slots on the reverse channel when said updated queuing position indicates that the first remote unit is free to transmit.
