RECONFIGURABLE INTELLIGENT SURFACE (RIS)-ENABLED FULL-DUPLEX USER EQUIPMENT SELF-LOCALIZATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18145644 titled 'RECONFIGURABLE INTELLIGENT SURFACE (RIS)-ENABLED FULL-DUPLEX USER EQUIPMENT SELF-LOCALIZATION

Simplified Explanation: The patent application describes a system where a user equipment (UE) can receive information about reconfigurable intelligent surfaces (RIS) to use during a self-localization positioning session. The UE is provided with a configuration for transmitting reference signals (RS) and a schedule for reflections from the RIS.

  • The user equipment (UE) can obtain information about reconfigurable intelligent surfaces (RIS) for use in self-localization positioning sessions.
  • The UE receives a configuration for transmitting reference signals (RS) during the positioning session.
  • A reflection schedule is provided for at least one RIS, indicating when and how the RIS will reflect the RS transmitted by the UE.

Potential Applications: 1. Indoor positioning systems for navigation in complex environments. 2. Enhanced wireless communication systems for improved signal strength and coverage. 3. Smart building technologies for optimizing energy efficiency and connectivity.

Problems Solved: 1. Difficulties in accurate self-localization in indoor environments. 2. Limited signal coverage and strength in wireless communication. 3. Inefficient use of reflective surfaces in buildings for connectivity enhancement.

Benefits: 1. Improved accuracy and reliability in indoor positioning. 2. Enhanced signal quality and coverage for better communication. 3. Energy-efficient and optimized connectivity solutions for smart buildings.

Commercial Applications: The technology can be applied in industries such as:

  • Telecommunications for improved network performance.
  • Smart home automation for enhanced connectivity.
  • Retail for indoor navigation and personalized marketing.

Questions about RIS: 1. How does the reflection schedule for RIS improve signal transmission? 2. What are the potential challenges in implementing RIS technology in real-world environments?

Frequently Updated Research: Researchers are exploring the integration of artificial intelligence with RIS technology to further enhance signal optimization and connectivity in various applications.


Original Abstract Submitted

In an aspect, a user equipment (UE) may obtain an indication of one or more reconfigurable intelligent surfaces (RIS) for use during a self-localization positioning session. The UE may receive a reference signal (RS) configuration for transmitting one or more RS for the self-localization positioning session. The UE may receive a reflection schedule for at least one RIS of the one or more RIS, wherein the reflection schedule indicates one or more reflection phases of the at least one RIS for reflecting the one or more RS transmitted by the UE and corresponding times at which each reflection phase of the one or more reflection phases is activated at the at least one RIS.
