Abstract: Exemplary embodiments of the invention include a request received to change a TX output power setting or a frequency channel setting. In response, the requested TX output power setting is used to generate a TX output signal in the proper frequency channel. Handset circuitry makes OOB power measurements, the results of which are used to determine a VCC2 setting. The VCC2 setting is a setting that results in an MPS requirement just being met. The VCC2 setting is stored in association with the TX output power and frequency channel setting. The determined VCC2 setting is also used to set the VCC2 supply voltage for the power amplifier. Once set, VCC2 remains fixed until the next request. Each individual handset uses this Adaptive Average Power Tracking (AAPT) method, thereby reducing its VCC2 voltage during operation and conserving power. Because each handset uses AAPT, factory calibration to account for unit-to-unit variations in transmitter circuitry performance is avoided.

Abstract: System for diverse path antenna selection. A method is provided for receiving a signal in a communication device having first and second antennas. The method includes receiving a first version of the signal using the first antenna, and receiving a second version of the signal using the second antenna. The method also includes determining a first quality indicator and a second quality indicator associated with the first and second versions of the signal, respectively, and selecting one of the first and second versions of the signal to process based on the first and second quality indicators.
