ENHANCED ASSISTANCE DATA FOR RADIO FREQUENCY SENSING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17836777 titled 'ENHANCED ASSISTANCE DATA FOR RADIO FREQUENCY SENSING

Simplified Explanation

The abstract describes a patent application related to radio frequency (RF) sensing of objects using a wireless network. The system includes a sensing node and a network node that use sensing assistance data to improve the accuracy of RF sensing.

  • The sensing assistance data includes information for estimating Doppler effect from received RF signals.
  • The information for Doppler estimation includes indicators of phase coherency of RF signals, such as phase coherence found in positioning reference signal (PRS) resources, resource sets, transmission reception points (TRPs), frequency layer, or a combination of these.
  • The sensing assistance data also includes an association of PRS resources and reference point objects (RPOs) to exclude RF signals reflected from the RPOs from the sensing measurements.
  • The sensing assistance data may also include beam pattern information for PRS resources to coordinate RF sensing.

Potential Applications

  • RF sensing can be used in various applications such as object detection, tracking, and localization.
  • This technology can be applied in smart homes to detect and track movement of individuals or objects.
  • It can be used in industrial settings for monitoring equipment or detecting anomalies.
  • RF sensing can also be utilized in healthcare for monitoring patient movement or detecting falls.

Problems Solved

  • RF sensing traditionally faces challenges in accurately estimating the Doppler effect caused by the movement of objects.
  • The association of PRS resources and RPOs helps exclude unwanted reflections from the sensing measurements, improving accuracy.
  • Coordinating the beam patterns of PRS resources further enhances the efficiency and effectiveness of RF sensing.

Benefits

  • Improved accuracy in RF sensing by estimating Doppler effect using sensing assistance data.
  • Exclusion of unwanted reflections from sensing measurements improves the reliability of the system.
  • Coordinating beam patterns enhances the overall performance and efficiency of RF sensing.
  • This technology enables a wireless network to effectively sense and track objects, leading to various applications in different industries.


Original Abstract Submitted

Radio frequency (RF) sensing of a target object by a wireless network is supported by a sensing node and a network node using sensing assistance data. The sensing assistance data may include information for Doppler estimation from received RF signals. The information for Doppler estimation, for example, may include an indication of phase coherency of RF signals, such as phase coherence found in positioning reference signal (PRS) resources, resource sets, transmission reception points (TRPs), frequency layer or any combination thereof. The sensing assistance data may include an association of PRS resources and reference point objects (RPOs) so RF signals reflected from the RPOs may be excluded from the sensing measurements. The sensing assistance data may include beam pattern information for PRS resources for beam coordination for RF sensing.
