Patent ID: 8160631

Claim:
A method performed in a wireless communication system, the method comprising: determining a first power level for one or more wireless communication devices configured for operation under a power constraint; wherein the first power level comprises a difference between a power level of at least one of the one or more wireless communication devices under the power constraint and a second power level of the at least one of the one or more wireless communication devices independent of the power constraint; obtaining a third power level of noise and interference signals surrounding the one or more wireless communication devices; estimating a fourth power level by filtering the third power level; determining a sum of the fourth power level and the first power level; setting a dynamic threshold value that comprises a product of a static rise-over-thermal threshold value and the sum; and setting a reverse activity bit of the wireless communication system when a Received Signal Strength Indication (RSSI) of the wireless communication system exceeds the dynamic threshold value.
