UPLINK AND DOWNLINK RIS-AIDED SIGNALING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18264528 titled 'UPLINK AND DOWNLINK RIS-AIDED SIGNALING

Simplified Explanation

The patent application describes a method for signal reporting using reconfigurable intelligent surfaces (RIS) in wireless communication. Here is a simplified explanation of the abstract:

  • A first wireless signaling device transmits a positioning reference signal (PRS) to a second wireless signaling device using a first RIS.
  • The first wireless signaling device receives a second PRS from the second wireless signaling device using a second physically separate RIS.
  • A signal report is generated, including time values corresponding to the transmission and reception times, and information about the first and second PRS.

Potential applications of this technology:

  • Improved wireless communication: The use of RIS can enhance the reliability and quality of wireless signals, leading to better communication between devices.
  • Positioning and tracking: The PRS can be used for positioning and tracking applications, such as in navigation systems or asset tracking.

Problems solved by this technology:

  • Signal interference: The use of RIS helps mitigate signal interference by optimizing the signal path between devices.
  • Signal strength and reliability: By using RIS, the signal strength and reliability can be improved, especially in challenging environments with obstacles or weak signals.

Benefits of this technology:

  • Enhanced signal quality: The use of RIS improves the quality of wireless signals, leading to better communication performance.
  • Increased coverage: RIS can extend the coverage area of wireless signals, allowing for communication in previously unreachable areas.
  • Efficient resource utilization: By optimizing the signal path, RIS helps in efficient utilization of wireless resources, reducing signal degradation and improving overall network performance.


Original Abstract Submitted

A signal reporting method includes: transmitting, from a first wireless signaling device at a first time, a first PRS (positioning reference signal) to a second wireless signaling device via a first RIS (reconfigurable intelligent surface); receiving, at the first wireless signaling device at a second time, a second PRS from the second wireless signaling device via a second RIS that is physically separate from the first RIS; and providing a signal report including at least one time value corresponding to the first time and the second time, and indicative of the first PRS and the second PRS.
