Abstract: Methods and apparatuses for a mobile station to obtain a position fix using synchronous hybrid positioning and asynchronous hybrid positioning techniques are described. In one embodiment, a wireless communication apparatus may transmit a request to a mobile station for fine time assistance (FTA) corresponding to a global navigation satellite system (GNSS). The apparatus may be configured to receive the FTA, first timing measurements from one or more base stations, and second timing measurements from the GNSS. The apparatus may identify whether the FTA was received from the mobile station. If it is determined that the FTA was received, then a system frame number (SFN) received within the FTA may be identified, wherein the SFN is associated with one of the base stations. The apparatus may then establish a position fix for the mobile station using a synchronous hybrid positioning technique that involves relating the timing measurements to a time scale associated with the SFN. If it is determined that the FTA was not received, then the apparatus may establish the position fix using an asynchronous hybrid positioning technique.

Abstract: In a tracking of a position and motion of a device, a set of hypothetical locations of the device is generated. Hypothetical locations among the set are propagated to respective hypothetical next locations, using respective location-specific propagation models associated with the hypothetical locations. Sensor information having correlation to a location of the device is received. An importance weighting for the hypothetical next locations is calculated using the new sensor information. Probable locations of the device are generated using the importance weighting.

Abstract: Systems, methods, and devices are described for estimating delay difference between two receive chains of a mobile device. The mobile device receives a first signal from a base station using a first receive chain, and receives a second signal using a second receive chain from a common, remote timing source for the base station and the mobile device. In addition, the mobile device obtains a transmit delay parameter associated with the base station and estimates, based at least in part on the transmit delay parameter, an offset value corresponding to a difference between amount of time for the first signal to pass through the first receive chain of the mobile device and amount of time for the second signal to pass through the second receive chain of the mobile device. The mobile device may store the offset value for subsequent use in estimating its position.
