Appl. No.:

13/487029

Inventors:

Benjamin A. Werner - San Carlos CA, US
Weihua Gao - San Jose CA, US

Assignee:

QUALCOMM INCORPORATED - San Diego CA

International Classification:

G01S 5/02

US Classification:

342451

Abstract:

An apparatus and method for building a base station almanac at a non-carrier location server is shown. A mobile device cooperates by informing the non-carrier location server of observed time difference of arrival (OTDOA) assistance data it receives. The non-carrier location server collects enough OTDOA assistance data through crowd souring or spoofing to generate an OTDOA library. The non-carrier location server using the OTDOA library to generate a base station almanac. Once created, non-carrier location server uses the base station almanac to provide assistance data to mobile devices without assistance from the carrier. Also, a mobile device may use the base station almanac to determine transmission timing between itself and neighboring and distant base stations.

International Classification:

H04W 24/00
H04W 88/02

US Classification:

4554566, 4555501

Abstract:

An apparatus and method for calculating time offsets for imperceptible base stations, which include base stations that have limited or no communication with a mobile station are presented. Time offsets for the imperceptible base stations are computed using transmit time offset information for a plurality of base station pairs received from a non-carrier base station almanac. A time offset between the mobile device at a first location and a serving base station at a second location is also computed. The time offsets for the imperceptible base stations may then be computed using the received transmit time offsets of the plurality of base station pairs and the time offset between the mobile device and the serving base station. The non-carrier base station almanac is built using a mobile device that informs a non-carrier location server of observed time difference of arrival (OTDOA) assistance data it receives from a carrier's location server.

International Classification:

G08G 5/00
B64C 39/02

Abstract:

Methods, systems, computer-readable media, and apparatuses for determining a flight route for a flight of an unmanned aerial vehicle (UAV) are presented. The flight-specific route for the UAV is determined dynamically during the flight or in advance before the flight, using navigation assistance data that includes flight-specific navigation assistance data for a plurality of geographic zones determined based on flight-specific information. The flight-specific navigation assistance data includes flight-specific ranking data for the plurality of geographic zones that can be used by the UAV or a server to determine the flight route.

International Classification:

G01P 3/00

Abstract:

Techniques are provided which may be implemented using various methods and/or apparatuses in a mobile GNSS device to compensate for arm swing. An example of an method for compensating for arm swing according to the disclosure includes determining an arm swing signal, such that the arm swing signal is approximately sinusoidal with a period of approximately T seconds, determining a position signal measurement period, receiving a plurality of positioning signals at intervals corresponding to the position signal measurement period, and determining current position information based on the plurality of positioning signals.

International Classification:

H04W 4/02

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.

International Classification:

H04W 64/00

US Classification:

4554561

Abstract:

Various arrangements for determining a location of a base station without timing synchronization are presented. A mobile device may determine that it is moving faster than a threshold velocity. The mobile device may capture a first unsynchronized time of arrival (TOA) measurement and determine an associated first location, wherein the first unsynchronized TOA measurement is based on a first unsynchronized timing measurement of a first received reference signal. The mobile device may capture a second unsynchronized TOA measurement and determine an associated second location, wherein the second unsynchronized TOA measurement is based on a second unsynchronized timing measurement of a second received reference signal. Based on the mobile device moving faster than the threshold velocity, the first location, the second location, the first unsynchronized TOA measurement, and the second unsynchronized TOA measurement may be used for determining the location of the base station.

Abstract:

Methods, devices, and systems are described for using multiple measurements including Doppler measurements from a mobile device to identify the position of the base station. Repeated Doppler and velocity measurements from different locations, with measurement groups taken at the same time or within a certain time frame, may be used to identify the location of a base station with which the mobile device is communicating.

International Classification:

H04L 1/00

US Classification:

370252

Abstract:

A method for blindly determining positioning reference signals in a wireless communication network determines a positioning reference signal (PRS) network configuration by estimating a PRS energy from predetermined locations of each subframe of an incoming signal. Such a method may also include blindly detecting PRS parameters based on the estimated PRS energy. The PRS energy may be peak energy responses for deep searches or verifications. The PRS energy may be a signal to signal plus noise ratio for shallow searches.
