Research on the Development of 6G Intelligent Reconfigurable Surface Technology Oriented Based on Patent Analysis

Abstract

Reconfigurable Intelligent Surface (RIS)' as one of the potential key technologies for 5G-Advanced and 6G' boasts ad- vantages such as quasi-passivity' continuous aperture' ease of deployment' low power consumption' software programmability' broad- band response' and low thermal noise. It has the capability to reshape the electromagnetic environment and enable a variety of func- tions. This study conducts a statistical analysis on the trends in application volume' regional distribution' and key players in technolog- ical innovation related to 6G intelligent surface technology patents. Furthermore' it examines the technological evolution paths of three main branches: RIS device' beamforming' channel estimation' and Integrated Sensing and Communication (ISAC). By relying on these patent technology evolution paths' the study uncovers the latest development trends and research hotspots in 6G intelligent surface technology. Through tracking and analyzing global patents focused on 6G intelligent surfaces' the technical information embedded in these patents is fully explored' highlighting the leading role of patent information in domestic technological development.
