Patent ID: 7289467

Claim:
A method for controlling connections between a base station and a plurality of customer premise equipment (CPEs) in a wireless communication system, wherein the base station and the CPEs each are configured to adaptively adjust a modulation scheme for an uplink which includes one or more connections, wherein a planned modulation scheme selected for the uplink and wherein a current modulation scheme corresponds to the modulation technique used by a first CPE to transmit data, the method comprising: receiving an uplink that is modulated by the first CPE using a current modulation scheme; determining a quality for a channel parameter for the uplink; comparing the quality with a current modulation scheme lower threshold; comparing the quality with a current modulation scheme upper threshold; if either the current modulation scheme upper or lower threshold has been crossed, determining a normalized hard bandwidth commitments for the uplink based on a second current modulation scheme to be used by the first CPE; if an air link line rate exceeds the normalized hard bandwidth commitments between the CPEs and the base station, applying the second current modulation scheme to the first CPE uplink, else suspending a connection between one of the plurality of CPEs and the base station.
