Abstract
Techniques for a high-accuracy determination the position of a light user equipment (UE) using a single base station are presented. This is accomplished by leveraging communications with a premium UE having a known location relative to the base station. Wireless reference signals measured by the light UE and premium UE, along with a reference signal from the light UE to the premium UE, can be used to determine the position of the light UE geometrically. The determination can be made by the light UE, premium UE, or a location server, depending on desired functionality.
Claims35
A method of determining a position of a first mobile device, the method comprising:
- determining a first time difference, wherein the first time difference comprises a time difference between:
- a time a first wireless reference signal transmitted by a network entity arrives at the first mobile device, and
- a time the first mobile device transmits a second wireless reference signal;
- determining a second time difference, wherein the second time difference comprises a time difference between:
- a time a third wireless reference signal transmitted by the network entity arrives at a second mobile device, and
- a time the second wireless reference signal arrives at the second mobile device;
- determining the position of the first mobile device based on the first time difference and the second time difference;
- and
- providing the position of the first mobile device.
A device comprising:
- a communication interface;
- a memory;
- and
- one or more processing units communicatively coupled with the communication interface and the memory and configured to:
- determine a first time difference, wherein the first time difference comprises a time difference between:
- a time a first wireless reference signal transmitted by a network entity arrives at a first mobile device, and
- a time the first mobile device transmits a second wireless reference signal;
- determine a second time difference, wherein the second time difference comprises a time difference between:
- a time a third wireless reference signal transmitted by the network entity arrives at a second mobile device, and
- a time the second wireless reference signal arrives at the second mobile device;
- determine a position of the first mobile device based on the first time difference and the second time difference;
- and
- provide the position of the first mobile device.
A device comprising:
- means for determining a first time difference, wherein the first time difference comprises a time difference between:
- a time a first wireless reference signal transmitted by a network entity arrives at a first mobile device, and
- a time the first mobile device transmits a second wireless reference signal;
- means for determining a second time difference, wherein the second time difference comprises a time difference between:
- a time a third wireless reference signal transmitted by the network entity arrives at a second mobile device, and
- a time the second wireless reference signal arrives at the second mobile device;
- means for determining a position of the first mobile device based on the first time difference and the second time difference;
- and
- means for providing the position of the first mobile device.
A non-transitory computer-readable medium storing instructions for determining a position of a first mobile device, the instructions comprising code for:
- determining a first time difference, wherein the first time difference comprises a time difference between:
- a time a first wireless reference signal transmitted by a network entity arrives at the first mobile device, and
- a time the first mobile device transmits a second wireless reference signal;
- determining a second time difference, wherein the second time difference comprises a time difference between:
- a time a third wireless reference signal transmitted by the network entity arrives at a second mobile device, and
- a time the second wireless reference signal arrives at the second mobile device;
- determining the position of the first mobile device based on the first time difference and the second time difference;
- and
- providing the position of the first mobile device.
