False Grant Detection Service for 5G UE Power Saving

The patent implements discontinuous reception (DRX) where the UE periodically monitors control channels during active periods and enters sleep mode during inactive periods. This periodic monitoring approach maintains message detection capability while significantly reducing power consumption compared to continuous monitoring, directly resolving the contradiction between reliability and energy usage.

The patent introduces a false grant detection service as an intermediary layer between grant detection and DRX Inactivity timer activation. This service verifies detected grants using HARQ processes and CRC checks before triggering timer activation, eliminating false positives while preserving legitimate grant responses. This resolves the contradiction by filtering out false detections that would otherwise cause unnecessary power consumption while maintaining network responsiveness to valid grants.

The patent converts the harmful effect of false grant detections (which cause unnecessary power consumption and overheating) into a beneficial verification mechanism. By implementing HARQ-based verification and CRC checks, the system identifies and eliminates false grants, transforming the problem of high power consumption in 5G networks into an opportunity to refine grant validation and reduce unnecessary energy expenditure during high-speed data transmission operations.
