RECONFIGURABLE INTELLIGENT SURFACE-BASED INTERFERENCE CANCELLATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17644279 titled 'RECONFIGURABLE INTELLIGENT SURFACE-BASED INTERFERENCE CANCELLATION

Abstract Explanation

The patent application describes techniques for using a reconfigurable intelligent surface (RIS) to cancel interference in wireless communication. The method involves determining when interference will occur at a first wireless node due to a signal transmitted by a second wireless node, and then using reflections from the RIS to cancel the interference.

Bullet Points

• Patent application describes techniques for interference cancellation using a reconfigurable intelligent surface (RIS).
• Method involves determining when interference will occur at a first wireless node.
• Interference is caused by a signal transmitted by a second wireless node.
• Reflections from the RIS are used to cancel the interference.

Potential Applications

• Wireless communication systems
• Cellular networks
• Internet of Things (IoT) devices
• Satellite communication systems

Problems Solved

• Interference in wireless communication
• Improving signal quality and reliability
• Enhancing network capacity and performance

Benefits

• Improved wireless communication performance
• Reduced interference and signal degradation
• Increased network capacity and efficiency

Original Abstract Submitted

Certain aspects of the present disclosure provide techniques for reconfigurable intelligent surface-based interference cancellation. A method that may be performed by a network entity generally includes determining to perform interference cancellation with a reconfigurable intelligent surface (RIS) for interference that will occur at a first wireless node based at least in part on one or more criteria, wherein the interference includes an interfering signal that will be transmitted by a second wireless node; and performing the interference cancellation with reflections from the RIS in response to the determination.
