    Abstract: Methods and apparatus are directed to mobile devices utilizing motion and/or position sensors for improving operating performance and/or power efficiency. In one example, a method for reducing power consumption in a mobile device includes receiving movement information, establishing movement data based on the movement information, determining if the mobile device is stationary using the movement data; and reducing the frequency of searching for a base station when the mobile device is stationary. In another example, a mobile device which reduces power consumption based upon movement data includes an RF front end, a receiver coupled to the RF front end, a data demodulator coupled to the receiver, a searcher, coupled to the RF front end and the receiver, which searches for base stations, and a processing unit coupled to the searcher, wherein the processing unit controls the searcher based upon the stationarity of the mobile device.

    Abstract: The subject matter disclosed herein relates to a system and method for estimating a location of a mobile station based, at least in part, on one or more measurements obtained from the mobile station based at least in part on one or more signals received by the mobile station from one or more signal sources. Such measurements may be combined based, at least in part, on estimates of measurement errors associated with the signal sources. In a particular implementation, such error estimates may be updated to account for changes in an operational environment.

    Abstract: A communication repeater for use in conjunction with a base transceiver subsystem (BTS) of a wireless communication system (Fig. 2). The repeater expands the coverage area of the BTS and allows receivers to identify whether the source of a communication signal was directly from a BTS or was broadcast by a repeater (Fig. 2, 212). Identification of the signal source facilitates position determination, particularly in hybrid position determination systems. The repeater implements differential delay modulation of the transmitted signal. The repeater re-transmits the original BTS signal as well as a time delayed version of the signal. Additionally, the repeater introduces synthetic path diversity in the form of spatial diversity or polarity diversity to de-correlate the re-transmitted original signal from the time delayed signal. The repeater can broadcast the delayed signal with the same power as the re-transmitted original signal or can attenuate the delayed signal relative to the re-transmitted original signal.
