Abstract:
1. A method for adapting a wireless communications link between a transmitter and a receiver wherein information is communicated in a downlink direction from a base transceiver station to multiple subscriber units and in an uplink direction from said multiple subscriber units to said base transceiver station comprising: establishing a radio frequency (RF) bandwidth as a communications channel in a wireless communications system; establishing a desired channel quality for uplink communications between said transmitter and said receiver over said communications channel; reducing said RF bandwidth of said communications channel for uplink communications to achieve said desired channel quality; allocating additional uplink time slots for uplink communications over said communications channel with said reduced RF spectrum to maintain a desired uplink transmission rate between said transmitter and said receiver over said communications channel with said reduced RF spectrum; and taking time slots from other uplink communications channels to compensate for said additional uplink time slots that are allocated to said uplink communications channel with said reduced RF spectrum.
