TIME REVERSAL FOR ON-DEMAND POSITIONING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18284522 titled 'TIME REVERSAL FOR ON-DEMAND POSITIONING

Simplified Explanation

The abstract describes methods and apparatus for on-demand transmission of time reversal (TR) precoded positioning signals. Here is a simplified explanation of the patent application:

  • User equipment (UE) can request transmission of positioning signals from a base station using TR precoding.
  • The UE transmits signals to the base station.
  • The base station sends the requested positioning signals to the UE based on the request and transmitted signals.
      1. Potential Applications

This technology can be applied in various industries such as telecommunications, navigation systems, and location-based services.

      1. Problems Solved

This innovation solves the problem of efficiently transmitting positioning signals using TR precoding, improving accuracy and reliability of location-based services.

      1. Benefits

The benefits of this technology include enhanced positioning accuracy, reduced interference, and improved signal quality for location-based services.

      1. Potential Commercial Applications

Potential commercial applications include 5G networks, IoT devices, autonomous vehicles, and smart city infrastructure.

      1. Possible Prior Art

One possible prior art could be the use of traditional precoding techniques for positioning signal transmission in wireless communication systems.

    1. Unanswered Questions
      1. How does this technology impact battery life in user equipment?

The abstract does not mention the impact of this technology on the battery life of user equipment. It would be interesting to know if TR precoding has any effect on power consumption.

      1. Are there any limitations to the range of positioning signals using this method?

The abstract does not address any limitations on the range of positioning signals transmitted using TR precoding. It would be important to understand if there are any distance constraints or signal degradation issues.


Original Abstract Submitted

Methods and apparatus for on-demand transmission of time reversal (TR) precoded positioning signals are disclosed. In an example method, a user equipment (UE) may transmit a request for transmission of one or more positioning signals from a base station, the request associated with a TR precoding, transmit one or more signals to the base station, and receive from the base station the one or more positioning signals based at least in part on the transmitted request and the one or more transmitted signals.
