Title:
RECONFIGURABLE INTELLIGENT SURFACE (RIS) -BASED SENSING WITH INTERFERENCE MITIGATION
Document Type and Number:
WIPO Patent Application WO/2024/087048
Kind Code:
A1
Abstract:
Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, according to aspects described herein, a reconfigurable intelligent surface (RIS) can receive a configuration message comprising an indication to reduce a gain of at least a portion of a reflection beam. The RIS can generating reflection coefficients for meta-elements of the RIS based on the configuration message. The RIS can configure the meta-elements based on the reflection coefficients. For instance, based on configuring the meta-elements, the RIS can generate or produce the reflection beam (e.g., a sensing reflection beam or an interference reflection beam) by reflecting a sensing signal received from a sensing transmitter device.
