TECHNIQUES FOR BEAM FAILURE RECOVERY IN MULTI-PATH COMMUNICATIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17940905 titled 'TECHNIQUES FOR BEAM FAILURE RECOVERY IN MULTI-PATH COMMUNICATIONS
Simplified Explanation
The patent application describes methods, systems, and devices for wireless communications involving beam failure recovery.
- User equipment (UE) can communicate with a network entity using directional beams.
- The UE can detect a beam failure and calculate the duration between the failure and a subsequent random access occasion.
- A Beam Failure Recovery (BFR) message is transmitted by the UE to the network entity or a second UE based on the calculated duration satisfying a threshold.
- If the duration is greater than or equal to the threshold, the BFR message is sent to the second UE. If less than the threshold, it is sent to the network entity.
Potential Applications
- 5G and future wireless communication systems
- Internet of Things (IoT) devices
- Autonomous vehicles
Problems Solved
- Efficient beam failure recovery in wireless communication
- Improved reliability of communication links
- Enhanced user experience in high-speed mobility scenarios
Benefits
- Faster recovery from beam failures
- Increased network reliability
- Better quality of service for users
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a network entity using one or more directional beams. The UE may detect a beam failure associated with at least one of the one or more directional beams, and the UE may calculate a duration between a detected beam failure and a subsequent random access occasion. The UE may transmit a beam failure recovery (BFR) message indicating the detected beam failure to the network entity or to a second UE based on whether the calculated duration satisfies a threshold duration. For example, the UE may transmit the BFR message to the second UE when the calculated duration is greater than or equal to the threshold duration. Alternatively, the UE may transmit the BFR message to the network entity when the calculated duration is less than the threshold duration.
