METHOD AND APPARATUS FOR PERFORMING DAS-BASED POSITIONING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17905839 titled 'METHOD AND APPARATUS FOR PERFORMING DAS-BASED POSITIONING

Simplified Explanation

The proposed patent application describes a method for operating a first device in a wireless communication system. The method involves receiving a positioning reference signal (PRS) from a second device using three antennas. By analyzing the reception times of the PRS on different antennas, the method calculates time differences and uses them to determine the location of the first device.

  • The method involves receiving a positioning reference signal (PRS) from a second device using three antennas.
  • The reception times of the PRS on different antennas are analyzed to calculate time differences.
  • The time differences are then used to determine the location of the first device.

Potential Applications

This technology can be applied in various fields where accurate location tracking is required, such as:

  • Asset tracking: The method can be used to track the location of valuable assets, such as equipment or vehicles, in real-time.
  • Navigation systems: By accurately determining the location of a device, this technology can enhance navigation systems for vehicles or pedestrians.
  • Emergency services: The method can aid emergency services in quickly locating individuals in need of assistance.

Problems Solved

The method described in the patent application addresses the following problems:

  • Accurate location tracking: By utilizing multiple antennas and analyzing reception times, the method improves the accuracy of determining the location of a device.
  • Wireless communication limitations: The method overcomes the limitations of wireless communication systems by using a positioning reference signal to calculate time differences and determine location.

Benefits

The use of this technology offers several benefits:

  • Enhanced accuracy: By utilizing multiple antennas and analyzing reception times, the method provides a more accurate determination of a device's location.
  • Real-time tracking: The method allows for real-time tracking of devices, enabling timely decision-making and improved operational efficiency.
  • Improved emergency response: The ability to quickly and accurately locate individuals in emergency situations can significantly improve response times and potentially save lives.


Original Abstract Submitted

Proposed is an operation method for a first device () in a wireless communication system. The method may comprise the steps of: receiving a first positioning reference signal (PRS) from a second device (), on the basis of a first antenna (-), a second antenna (-), and a third antenna (-); obtaining a first time difference, on the basis of a first reception time at which the first PRS is received on the basis of the first antenna (-) and a second reception time at which the first PRS is received on the basis of the second antenna (-); obtaining a second time difference, on the basis of a third reception time at which the first RPS is received on the basis of the third antenna (-) and the first reception time; and obtaining the location of the first device (), on the basis of the first time difference and the second time difference.
