Patent ID: 7085228

Claim:
A method for adaptive radio resource management in a wireless communication system, the system including an access point and at least one wireless transmit/receive unit (WTRU), the method comprising the steps of: examining a frame error rate value of a WTRU; examining a channel utilization value of the WTRU; examining a current data rate of the WTRU; adjusting system parameters for the WTRU based on the examined variables, the adjusting step being performed by one of rate control, congestion control, and traffic shaping; wherein rate control is performed if one of the following conditions is satisfied: the channel utilization value is below a low channel utilization threshold and the current data rate is above a minimum data rate threshold; and the frame error rate value is below a low frame error rate threshold, the channel utilization value is above a high channel utilization threshold, and the current data rate is below a maximum data rate threshold; wherein congestion control is performed if the frame error rate value is above a low frame error rate threshold and the channel utilization value is above a high channel utilization threshold; and wherein traffic shaping is performed if one of the following conditions is satisfied: the frame error rate value is above a high frame error rate threshold and the channel utilization value is above a low channel utilization threshold; and the frame error rate value is above a high frame error rate threshold, the channel utilization value is below a low channel utilization threshold; and the current data rate is equal to a minimum data rate threshold.
