Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus configured to establish a wireless connection to a first network, tune away from the first network for a first predetermined interval, tune back to the first network after the first predetermined interval, enter a power control freeze state for a second predetermined interval after tuning back to the first network, send a plurality of transmissions to the first network during the second predetermined interval, determine if a number of the plurality of transmissions that are not received by the first network exceeds a first threshold or if a number of the plurality of transmissions that are retransmitted to the first network exceeds a second threshold, and exit the power control freeze state when it is determined that the first threshold is exceeded or when it is determined that the second threshold is exceeded.

Abstract: A system and method is provided for tuning a Global Positioning System (GPS) antenna matching circuit in a portable wireless communications device. The method includes accepting a first matching circuit tuning value, measuring satellite vehicle (SV) carrier-to-noise ratio (C/N) associated with the first tuning value and a first search time interval, measuring the SV C/N associated with a next tuning value, and selecting the tuning value associated with the highest SV C/N to tune the matching circuit. In one aspect, the method further includes comparing the SV C/N to a first minimum threshold. If the first tuning value SV C/N exceeds the first minimum threshold, then the method measures the SV C/N associated with the next tuning value. Otherwise, a default tuning value can be selected to tune the matching circuit.
