Abstract

Disclosed is a method and apparatus for utilizing an array of one or more mobile devices to perform a task. The method may include accessing a task to be performed using the array of one or more mobile devices. The task may include user equipment positioning, imaging a real world area, or a combination thereof. The method may also include receiving signals collected by the array of one or more mobile devices while the task is being performed, and determining an uncertainty of a result of the task being performed based, at least in part, on one or more characteristics associated with the array of mobile devices and the task being performed. Furthermore, the method may include adjusting the array of mobile devices to reduce the uncertainty of the result of the task being performed.

Claims

1. A method for utilizing an array of one or more mobile devices to improve one or more positioning metrics of a user equipment, the method comprising:

receiving positioning metrics associated with signals collected by the one or more mobile devices in the array, wherein the signals are wireless communication network signals generated by the user equipment;

determining a first position of the user equipment based on the positioning metrics;

determining a new position for at least one mobile device in the array of the one or more mobile devices based on the first position of the user equipment;

transmitting the new position to the at least one mobile device;

receiving new positioning metrics associated with signals collected by the at least one mobile device at the new position; and

determining a second position of the user equipment based on the positioning metrics and the new positioning metrics.

2. The method of claim 1, wherein the user equipment comprises a mobile device.

3. The method of claim 1, wherein the array of the one or more mobile devices comprises one or more unmanned vehicles, one or more manned vehicles, or a combination thereof.

4. The method of claim 1, further comprises:

determining an uncertainty of the determined position of the user equipment based on the positioning metrics, wherein the positioning metrics are indicative of a precision of the associated signals and comprise;

a signal strength, an orientation of the one or more mobile devices in the array when the signal was captured, signal timing data, relative signal timing associated with signals received at different mobile devices within the one or more mobile devices in the array, signal power, a location of a mobile device within the array of the mobile devices, relative locations of the at least one mobile device from the one or more mobile devices in the array, or any combination thereof; and

wherein the determining the new position for the at least one mobile device in the array of the mobile devices is further based on the uncertainty of the determined position of the user equipment.

5. A system for utilizing an array of one or more mobile devices to improve one or more positioning metrics of a user equipment, the system comprising:

a memory to store received positioning metrics associated with signals collected by the one or more mobile devices in the array, wherein the signals are wireless communication network signals generated by the user equipment; and

one or more processors coupled with the memory configured to;

determine a first position of the user equipment based on the positioning metrics; and

determine a new position for at least one mobile device in the array of the one or more mobile devices based on the first position of the user equipment;

transmit the new position to the at least one mobile device;

receive new positioning metrics associated with signals collected by the at least one mobile device at the new position; and

determine a second position of the user equipment based on the positioning metrics and the new positioning metrics.

6. The system of claim 5, wherein the array of one or more mobile devices comprises one or more unmanned vehicles, one or more manned vehicles, one or more drone aircraft, or a combination thereof.

7. An apparatus for utilizing an array of one or more mobile devices to improve one or more positioning metrics of a user equipment, comprising:

means for receiving positioning metrics associated with signals collected by the one or more mobile devices in the array, wherein the signals are wireless communication network signals generated by the user equipment;

means for determining a first position of the user equipment based on the positioning metrics;

means for determining a new position for at least one mobile device in the array of the one or more mobile devices, based on the first position of the user equipment;

means for transmitting the new position to the at least one mobile device; and

means for receiving new positioning metrics associated with signals collected by the at least one mobile device at the new position; and

means for determining a second position of the user equipment based on the positioning metrics and the new positioning metrics.

8. A non-transitory computer readable storage medium for utilizing an array of one or more mobile devices to improve one or more positioning metrics of a user equipment comprising processor-executable program code configured to cause one or more processors to:

receive positioning metrics associated with signals collected by the one or more mobile devices in the array, wherein the signals are wireless communication network signals generated by the user equipment;

determine a first position of the user equipment based on the positioning metrics; and

determine a new position for at least one mobile device in the array of the one or more mobile devices based on the first position of the user equipment;

transmit the new position to the at least one mobile device;

receive new positioning metrics associated with signals collected by the at least one mobile device at the new position; and

determine a second position of the user equipment based on the positioning metrics and the new positioning metrics.
