NEAR/FAR-FIELD DETERMINATION OF RECONFIGURABLE INTELLIGENT SURFACE (RIS) FOR MOBILE DEVICE POSITIONING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18259774 titled 'NEAR/FAR-FIELD DETERMINATION OF RECONFIGURABLE INTELLIGENT SURFACE (RIS) FOR MOBILE DEVICE POSITIONING
Simplified Explanation
Techniques for determining reconfigurable intelligent surface (RIS) operation for RIS-assisted position determination of a mobile device in a wireless communications system may include:
- Determining if the mobile device is within a near-field operational distance of the RIS based on the near-field operational distance of the RIS and the relative distance between the mobile device and the RIS.
- Determining the RIS-assisted position of the mobile device based on measurements of RF signals reflected from at least one RIS.
- Providing the determined RIS-assisted position of the mobile device.
- Potential applications of this technology:**
- Enhanced indoor positioning for mobile devices - Improved signal coverage and quality in wireless communications systems
- Problems solved by this technology:**
- Inaccurate or unreliable positioning of mobile devices in indoor environments - Limited signal coverage and quality in wireless communications systems
- Benefits of this technology:**
- More accurate and reliable positioning of mobile devices - Enhanced signal coverage and quality for improved communication experiences
Original Abstract Submitted
Techniques for determining reconfigurable intelligent surface (RIS) operation for RIS-assisted position determination of a mobile device in a wireless communications system, according to this disclosure, may comprise determining, for one or more RISs, whether the mobile device is within a near-field operational distance of the RIS based at least in part on a determined near-field operational distance of the RIS, and a relative distance between the mobile device and the RIS. Techniques may also comprise determining an RIS-assisted position of the mobile device based on measurements made by the mobile device of radio frequency (RF) signals reflected from at least one RIS of the one or more RISs. Techniques may also comprise providing the determined RIS-assisted position of the mobile device.
