First Claim
1. A method to reduce power consumption in a mobile station, comprising:
- determining in the mobile station whether there is a decreased probability of a presence of at least one transmitter near to the mobile station that is transmitting a potentially interfering signal relative to a frequency channel being received from a serving cell transmitter; and
for a case where it is determined that there is a decreased probability of the presence of the at least one transmitter, changing the operation of at least one receiver component so as to decrease a receiver other channel suppression characteristic and to decrease mobile station power consumption.

Abstract
A method is disclosed for operating a mobile station (100) by determining whether there is a decreased probability of a presence of a transmitter (4) near to the mobile station that is transmitting on a frequency channel that is adjacent to a frequency channel being received from a serving cell transmitter (2) and, for a case where it is determined that there is a decreased probability of the presence of the transmitter, reducing the filter order of a baseband filter (224) of the mobile station and reducing the dynamic range of an analog to digital converter (225) of the mobile station for reducing mobile station power consumption. Reducing the filter order further beneficially reduces inter-symbol interference. In one embodiment the step of determining determines a speed of the mobile station, and correlates the speed with the probability of the presence of the transmitter such that at a lower speed the determination is that the probability is increased and at a higher speed the determination is that the probability is decreased. A measurement of adjacent channel transmitted power may be used as a verification. The speed is determined based at least in part on an output (184) of a mobile station automatic frequency control function. In another embodiment the step of determining employs information received from a network operator location services function (60). The mobile station can also determine if there is a decreased probability of a presence of a transmitter near to the mobile station that is transmitting on a frequency channel that may cause Inter-Modulation Distortion with a frequency channel being received from a serving cell transmitter. For a case where it is determined that there is a decreased probability of the presence of the transmitter, the method reduces the linearity of the receiver for reducing mobile station power consumption.
