    • An apparatus and method for dual mode power control. A transmitter is capable of operating in a first mode of operation and a second mode of operation, the first mode of operation and the second mode of operation including a closed loop control mode and an open loop control mode, the first mode of operation being different from the second mode of operation. The transmitter can be operated in the first mode of operation. A transmitter output power characteristic of the first mode of operation can be read back. The transmitter output power characteristic of the first mode of operation can be correlated to a transmitter output power characteristic of the second mode of operation. The first mode of operation can be switched to the second mode of operation based on the transmitter output power characteristic of the second mode of operation.

    • An apparatus and method for transmission power amplifier bias control in an enhanced data rate for global system mobile evolution mobile communication device. The apparatus can include a transmitter configured to transmit information on an enhanced data rate for global system mobile evolution network at a first transmitter output power. The transmitter can include 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 configured to provide the first transmitter output power for transmitting the symbols represented by eight phase offsets. The apparatus can also include a controller configured to adjust a first bias condition of the power amplifier to a second bias condition based on a changed parameter of operation related to the data stored in a memory.
