BEAM FAILURE RECOVERY VIA SIDELINK - A simplified explanation of the abstract
This abstract first appeared for US patent application 17848285 titled 'BEAM FAILURE RECOVERY VIA SIDELINK
Simplified Explanation
The patent application describes methods, systems, and devices for wireless communications. It introduces a concept called beam failure recovery (BFR) that allows a user equipment (UE) to recover from a beam failure during communication with a network node.
- A first UE communicates with a network node using a first wireless link and a first beam configuration.
- If a beam failure is identified for the first beam, the first UE transmits a BFR message to the network node via a second wireless link with a second UE.
- The network node responds by transmitting a message indicating a second beam configuration to the first UE.
- The second beam configuration includes a new beam for the first UE to use for communication.
- Additionally, the network node may instruct the second UE to relay traffic between the network node and the first UE.
Potential Applications
- Wireless communication systems
- Mobile networks
- Internet of Things (IoT) devices
- Satellite communication systems
Problems Solved
- Beam failures during wireless communication can disrupt the connection between a UE and a network node.
- Recovering from beam failures quickly and efficiently is crucial for maintaining uninterrupted communication.
- This technology provides a mechanism for identifying and recovering from beam failures, ensuring continuous communication.
Benefits
- Improved reliability of wireless communication systems.
- Faster recovery from beam failures, minimizing downtime.
- Enhanced user experience with seamless connectivity.
- Efficient utilization of wireless resources.
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may communicate with a network node via a first wireless link using a first beam according to a first beam configuration. In some examples, the first UE may transmit to the network node via a second wireless link with a second UE, a beam failure recovery (BFR) message in response to identifying a beam failure for the first beam. As such, the UE may receive, a message indicating a second beam configuration. For example, the network node transmit to the first UE via a third wireless link, the second beam configuration including a second beam for the first UE to use to communicate. Additionally, or alternatively, the network node may transmit to the second UE, a signal indicating for the second UE to relay traffic between the network node and the first UE.
