Predictive Power Headroom Reporting for Low-Latency Uplink Control

The patent applies preliminary action by predicting channel metrics (such as path loss) at a future time instance before actual transmission occurs. The network entity calculates predicted path loss based on current channel conditions and projects them forward in time, allowing the UE to prepare power headroom reports in advance. This proactive approach eliminates waiting time for actual channel measurements at the future time instance, thereby reducing latency in uplink power control while maintaining accuracy.

The patent applies parameter changes by transforming the approach from using actual measured channel metrics at future time instances to using predicted metrics derived from current measurements. The network entity changes the parameter representation from raw measured values to projected values based on prediction algorithms (such as linear extrapolation or machine learning models). This allows the system to work with simplified predictive parameters rather than complex real-time measurements, reducing computational burden while maintaining the latency benefits of prediction.
