TECHNIQUES FOR USING REFLECTING NODES TO CANCEL INTERFERING SIGNALS IN WIRELESS COMMUNICATIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17384300 titled 'TECHNIQUES FOR USING REFLECTING NODES TO CANCEL INTERFERING SIGNALS IN WIRELESS COMMUNICATIONS
Simplified Explanation
The abstract of this patent application describes a method for identifying and mitigating interference caused by an aggressor node in a wireless communication network. Here is a simplified explanation of the abstract:
- The technology identifies a node that is transmitting interfering signals, which are causing interference to the signals received at another node.
- A configuration is then communicated to a reflecting node, instructing it to apply a phase shift to the interfering signals.
- The reflecting node forwards the interfering signals to the affected node with the phase shift applied, aiming to partially cancel out the interference.
Potential Applications
This technology can have various applications in wireless communication systems, including:
- Cellular networks: It can be used to identify and mitigate interference between base stations or between base stations and user devices, improving overall network performance.
- Wi-Fi networks: It can help in reducing interference between neighboring access points, leading to better signal quality and higher data rates.
- Internet of Things (IoT): This technology can be applied to minimize interference between IoT devices operating in close proximity, ensuring reliable and efficient communication.
Problems Solved
The technology addresses the following problems in wireless communication networks:
- Interference identification: It provides a method to identify the specific node causing interference, allowing for targeted mitigation measures.
- Interference cancellation: By applying a phase shift to the interfering signals, the technology aims to cancel out the interference, improving signal quality and reducing data errors.
- Efficient communication: The use of reflecting nodes allows for the interference cancellation to be performed closer to the affected node, minimizing the impact on network resources.
Benefits
The technology offers several benefits for wireless communication systems:
- Improved signal quality: By mitigating interference, it enhances the overall signal quality, leading to better data transmission and reception.
- Increased network capacity: By reducing interference, the technology can increase the capacity of the network, allowing for more devices to connect and communicate simultaneously.
- Enhanced user experience: With reduced interference and improved signal quality, users can enjoy faster and more reliable wireless connections.
- Cost-effective solution: The use of reflecting nodes and targeted interference cancellation helps optimize network resources, making the technology a cost-effective solution for improving wireless communication performance.
Original Abstract Submitted
Aspects described herein relate to identifying an aggressor node that transmits interfering signals that cause interference to signals received at the node, communicating a configuration for applying a phase shift to the interfering signals for forwarding to the node from a reflecting node with the phase shift applied, and communicating, from the reflecting node, the interfering signals with the phase shift applied to at least partially cancel the interference to the signals received at the node.
