First Claim
Patent Images
1. A method for jointly adapting power and data transmission rate in a wireless network, comprising:
- setting a transmission rate for a mobile station;
measuring a signal quality for the mobile station;
adjusting, if necessary, a transmission power level towards a power control target associated with the transmission rate; and
adjusting, if necessary, the transmission rate for the mobile station based upon signal quality measured over a period of time.

17. A method for adapting transmission power and transmission rate in a wireless network, comprising:
-
measuring a link quality of a first link in the wireless network;
decreasing a current transmission power for the first link if the measured link quality is greater than a target link quality associated with a current transmission rate;
increasing the current transmission power for the first link if the measured link quality is less than the target link quality associated with the current transmission rate;
maintaining the current transmission power for the first link if the measured link quality is not less than or greater than the link quality associated with the current transmission rate;
determining an average link quality measure at predetermined intervals;
incrementing or decrementing a counter value based upon a comparison of the average link quality measure and a predetermined threshold; and
increasing or decreasing the current transmission rate for a next one of the predetermined intervals. - View Dependent Claims (18, 19, 20)
