Patent ID: 7342955

Claim:
An enhanced data rate for global system mobile evolution mobile communication device comprising: an antenna; a receiver coupled to the antenna, the receiver configured to receive, from an enhanced data rate for global system mobile evolution base station, a first time slot assignment and a first power level requirement associated with the first time slot assignment; a transmitter coupled to the antenna, the transmitter configured to transmit information on an enhanced data rate for global system mobile evolution network at a first transmitter output power based on the first power level requirement, the transmitter including: a modulator configured to receive an input signal and map information in the input signal to symbols represented by eight phase offsets; and a power amplifier coupled to the modulator and coupled to the antenna, the power amplifier providing the first transmitter output power for transmitting the symbols represented by eight phase offsets, the power amplifier operating at a first operating point set by a first bias condition based on the first power level requirement; a memory including data stored in the memory, the data related to parameters of operation of the enhanced data rate for global system mobile evolution mobile communication device, the parameters of operation including bias conditions and power level requirements; and a controller coupled to the power amplifier and coupled to the memory, the controller configured to adjust the first bias condition to a second bias condition based on a changed parameter of operation related to the data stored in the memory.
