REFERENCE SIGNAL TIME DIFFERENCE (RSTD) MEASUREMENT REPORT ENHANCEMENTS FOR MULTI-TIMING ERROR GROUP (TEG) REQUESTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18540414 titled 'REFERENCE SIGNAL TIME DIFFERENCE (RSTD) MEASUREMENT REPORT ENHANCEMENTS FOR MULTI-TIMING ERROR GROUP (TEG) REQUESTS

Simplified Explanation

The abstract describes techniques for wireless positioning, where a first network node measures a positioning reference signal (PRS) resource from at least one second network node using a plurality of receive timing error groups (Rx TEGs) and transmits a measurement report to a location server.

  • Wireless positioning technique using Rx TEGs:
   - The first network node measures a PRS resource from a second network node using Rx TEGs.
   - The measurement report includes positioning measurements based on the PRS resource corresponding to the Rx TEGs.
  • Measurement request and report transmission:
   - The first network node receives a measurement request from a location server.
   - The measurement report is transmitted to the location server.
  • Potential applications of this technology:
   - Enhanced location-based services
   - Improved indoor positioning systems
  • Problems solved by this technology:
   - Accurate wireless positioning in challenging environments
   - Efficient utilization of network resources for positioning
  • Benefits of this technology:
   - Increased accuracy in wireless positioning
   - Enhanced user experience for location-based services
  • Potential commercial applications of this technology:
   - Navigation and mapping services
   - Asset tracking and management solutions
  • Possible prior art:
   - Existing wireless positioning techniques using different measurement methods

Questions:

1. How does this technique improve the accuracy of wireless positioning compared to traditional methods? 2. What are the potential challenges in implementing this wireless positioning technique in real-world networks?


Original Abstract Submitted

Disclosed are techniques for wireless positioning. In an aspect, a first network node receives a measurement request from a location server, the measurement request requesting the first network node to measure a positioning reference signal (PRS) resource from at least one second network node using a plurality of receive timing error groups (Rx TEGs) of the first network node, and transmits a measurement report to the location server, the measurement report including a plurality of positioning measurements based on the PRS resource, the plurality of positioning measurements corresponding to the plurality of Rx TEGs.
