1Measurement precision

If clock quality information is transmitted to all UEs, then time synchronization accuracy is improved, but signaling overhead increases

Engineering Contradiction:
Improvetime synchronization accuracyVSAvoidsignaling overhead
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent applies local quality by differentiating clock quality information delivery based on individual UE requirements. The network device determines whether to transmit clock quality information to each UE based on subscription information and application-specific accuracy requirements. This selective approach ensures that only UEs needing high-precision time synchronization receive detailed clock quality information, thereby reducing overall signaling overhead while maintaining accuracy for applications that require it.

2Measurement precision

If detailed clock quality information is provided, then application accuracy requirements are met, but system complexity increases

Engineering Contradiction:
Improveclock accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent implements dynamics by making the clock quality information delivery adaptive and configurable. The network device receives clock quality reporting control information that indicates whether to provide default or detailed clock quality information. This dynamic configuration allows the system to adjust the level of information provided based on real-time requirements, balancing accuracy needs with system complexity. The configurable nature enables the system to scale complexity only when and where high precision is actually needed.
