Abstract

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.
