1. A method for dynamically allocating uplink bandwidth in a base station for a broadband wireless communication system where the base station exchanges uplink (UL) and downlink (DL) traffic with one or more remote units over a shared uplink and a shared downlink, the method comprising:

  • generating at the base station a DL map and a UL map with current DL bandwidth allocations and current UL bandwidth allocations and periodically transmitting the maps to said remote units;

    identifying within the UL traffic received from a remote unit, a bandwidth request specifying a requested amount of UL bandwidth;

    based on said specified requested amount of UL bandwidth and on UL bandwidth available for sharing on said shared uplink, allocating an UL bandwidth grant to said remote unit; and

    updating said UL map to account for said UL bandwidth grant.
