Event-Triggered UE Beam Reporting for Lower Uplink Overhead

The patent implements event-triggered beam reporting where the UE periodically monitors beam quality metrics (such as RSRP, SINR) and only transmits beam reports when predefined events/conditions are met. This replaces traditional periodic reporting with a hybrid approach that maintains periodic monitoring but eliminates periodic transmission, reducing overhead while preserving beam management capability.

The UE autonomously determines when to trigger beam reports based on locally evaluated events and conditions without requiring network scheduling commands. The UE self-manages the reporting process by monitoring its own beam quality metrics and initiating reports only when necessary, reducing control signaling overhead.

The network configures event-triggered reporting parameters and thresholds, and the UE provides feedback reports only when beam quality changes exceed these thresholds. This feedback mechanism ensures the network receives timely beam information updates without requiring continuous reporting, optimizing the balance between information freshness and resource consumption.

The patent changes the reporting parameter from fixed periodic intervals to event-driven variable intervals. The reporting frequency dynamically adjusts based on beam quality conditions, increasing reporting frequency only when beam degradation is detected and maintaining low frequency when conditions are stable, thereby conserving network resources while maintaining information freshness.
