1. A base station for use in a broadband wireless communication system, wherein the wireless communication system includes a plurality of customer premise equipment (CPE) in communication with the base stations, the base station comprising:

  • means for maintaining uplink and downlink sub-frame maps representative of the bandwidth allocations in uplink and downlink communication paths; and

    means for allocating bandwidth configured to determine whether there is sufficient bandwidth available to individually poll a CPE, if sufficient bandwidth is available to individually poll a CPE, select a CPE to be polled, individually poll the selected CPE by allocating bandwidth to the selected CPE in the uplink sub-frame map, if the selected CPE transmits a bandwidth request, initiate a bandwidth allocation process to allocate bandwidth in the uplink sub-frame map for the selected CPE, and if there is not sufficient bandwidth available to individually poll a CPE, initiate a multicast and broadcast polling process.
