Abstract:
Disclosed is a method and apparatus for managing a driving plan of an autonomous vehicle. The method may include obtaining observations of a neighboring vehicle using one or more sensors of the autonomous vehicle. The method may also include classifying one or more behavioral driving characteristics of the neighboring vehicle based on the observations. Furthermore, the method may include updating the driving plan based on a classification of the one or more behavioral driving characteristics of the neighboring vehicle, and controlling one or more operations of the autonomous vehicle based on the updated driving plan.
Abstract:
A method of determining a location of a base station includes: receiving, at a mobile device from a location server, a base station identifier (BSID) of the base station and two or more candidate locations of the base station; receiving a signal, at the mobile device from the base station identified by the BSID; and selecting, at the mobile device, a particular candidate location from the two or more candidate locations based on a characteristic determined from the signal. A method of identifying an actual location of a base station includes: transmitting, from a location server to a disambiguating mobile device, a base station identifier (BSID) of the base station and two or more candidate locations of the base station; and receiving, at the location server from the disambiguating mobile device, an indication of the actual location of the base station from among the two or more candidate locations.
Abstract:
Methods and apparatus are described for providing location assistance information to a mobile device. An example of a method for providing location assistance information to the mobile device by a femto base station includes receiving a macro base station signal during a monitoring time period during which the femto base station is substantially stationary, obtaining location assistance information, the location assistance information being based, at least in part, on the received macro base station signal, and transmitting the location assistance information to the mobile device.
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.
Abstract:
Techniques described herein enable a mobile device in selecting an access point (AP) from a plurality of APs for determining the position of the mobile device. In one aspect, the mobile device receives assistance data including traffic load information associated with one or more APs. The mobile device may determine which AP to communicate with based on the traffic load information associated with a plurality of APs. The assistance data including the traffic load information associated with the plurality of APs may be compiled using information from a controller connected to the plurality of APs, crowdsourcing (using information from a plurality of mobile devices over time), or information regarding the traffic conditions received from the plurality of APs. In one implementation, the mobile device may receive the assistance data information including the traffic load information from an assistance data (AD) Server.
Abstract:
Disclosed are systems, methods and devices for application of determining position information for mobile devices. In specific implementations, measurement of a signal travel time and a signal's strength may be combined to characterize a transmission power of the signal's transmitter. The characterized transmission power may be applied to affect expected signal strength signature values for use of the signal's transmitter may be updated in order to enhance a location based service where location may be effected by accuracy of a transmitter's power.
Abstract:
Techniques are provided for providing a processing delay estimate of an access point, or turnaround calibration function (TCF), associated with round trip time (RTT) measurements. Mobile devices, access points, and/or other systems can utilize these techniques to derive processing delay from the RTT measurements. Crowdsourcing can also be used to help increase the accuracy of the processing delay estimate, which can be propagated to multiple devices.
Abstract:
A method for locating a target transceiver in a wireless communication system includes: obtaining at least one scan list indicating a set of transceivers including the target transceiver; identifying, from stored geotagging data, locations of at least some previously located transceivers represented in the at least one scan list that are distinct from the target transceiver; generating a list of neighbor transceivers corresponding to the target transceiver based on the at least one scan list; and calculating an estimated location of the target transceiver using the list of neighbor transceivers and the locations of the previously located transceivers represented in the at least one scan list.
Abstract:
Methods and apparatus for route selection to a destination may include receiving a starting point and one or more destinations, and transmitting a request to a server for routes associated with the starting point and the one or more destinations. Additionally, the methods and apparatus may include receiving, from the server, a plurality of routes to the one or more destinations. Furthermore, the methods and apparatus may include selecting a route from the plurality of routes based at least on one or more reliability parameters associated with each route of the plurality of routes, the one or more reliability parameters comprising a likelihood of determining a position location along each route, the likelihood being based at least on detectability of features in each route by one or more object detection modalities.
