Patent ID: 7835298

Claim:
A method of allocating a bandwidth and a power for a wireless user, the method comprising: determining an allocated bandwidth to be equal to a first bandwidth; determining a transmission power to be equal to a first power level; transmitting to a wireless user a wireless signal associated with the allocated bandwidth and the transmission power; determining a bit rate and an error rate for the transmitted signal; processing information associated with the bit rate and the error rate; determining whether the bit rate satisfies one or more predetermined first criteria and whether the error rate satisfies one or more predetermined second criteria; if the bit rate is determined not to satisfy the one or more predetermined first criteria and/or the error rate is determined not to satisfy the one or more predetermined second criteria, adjusting the transmission power from the first power level to a second power level so that the bit rate is determined to satisfy the one or more predetermined first criteria and the error rate is determined to satisfy the one or more predetermined second criteria; processing information associated with the adjusted transmission power; determining a power level indicator based on at least information associated with the adjusted transmission power; processing information associated with the power level indicator; determining whether the power level indicator satisfies one or more predetermined third criteria; if the power level indicator is determined not to satisfy the one or more predetermined third criteria, adjusting the allocated bandwidth from the first bandwidth to a second bandwidth for the wireless user; if the power level indicator is determined to satisfy the one or more predetermined third criteria, keeping the allocated bandwidth equal to the first bandwidth.
