Intellectual Property India Publishes Patent Application for 'Decomposition-Based Separated Channel Estimation And Sounding For Reconfigurable Intelligent Surfaces' Filed by Interdigital Patent Holdings, Inc.

MUMBAI, India, Aug. 22 -- Intellectual Property India has published a patent application (202517073469 A) filed by Interdigital Patent Holdings, Inc., Wilmington, U.S.A., on Aug. 1, for 'decomposition-based separated channel estimation and sounding for reconfigurable intelligent surfaces.'

Inventor(s) include Jagyasi, Deepa Gurmukhdas; Svedman, Patrick; Shojaeifard, Arman; Pan, Kyle Jung-Lin; and Tsai, Allan.

The application for the patent was published on Aug. 22, under issue no. 34/2025.

According to the abstract released by the Intellectual Property India: "A wireless transmit/receive unit (WTRU) may receive configuration information that indicates a channel state information (CSI) resource and information associated with separate reporting for a base station (BS)-reconfigurable intelligent surface (RIS) channel and a RIS-WTRU channel. The WTRU may measure a BS-RIS-WTRU channel using the indicated CSI resource and determine separated CSI for the BS-RIS channel and the RIS-WTRU channel based on the measurement for the BS-RIS-WTRU channel. The WTRU may then send the separated CSI for the BS-RIS channel and the RIS-WTRU channel. The measurement for a BS-RIS-WTRU channel may include a differential CSI measurement, and the separated CSI may be determined based on the differential CSI measurement. The differential CSI measurement may be performed by varying RIS states."

The patent application was internationally filed on Feb. 01, 2024, under International application No.PCT/US2024/014057.
