Real Time Difference Reporting for 5G Positioning

The patent applies local quality by making the RTD reporting behavior cell-specific rather than uniform across all cells. The UE is configured to report RTD values only for specific cells where the timing synchronization offset has changed, rather than reporting for all cells unconditionally. This selective reporting approach reduces overall signaling overhead while maintaining location determination accuracy for the relevant cells.

The patent implements dynamics by making the RTD reporting mechanism adaptive and event-driven. The UE monitors timing synchronization offset changes dynamically and triggers RTD value reporting only when changes are detected. This dynamic approach ensures that location accuracy is maintained through timely updates while minimizing unnecessary signaling when no changes occur.

The patent applies local quality by focusing timing synchronization efforts on individual cells rather than requiring uniform precision across the entire network. Each cell's RTD value is determined and reported independently based on its specific timing relationship with the reference cell, allowing the system to achieve positioning accuracy through localized synchronization management rather than global precision requirements.

The patent segments the timing synchronization problem into cell-specific RTD value determinations rather than requiring monolithic network-wide synchronization. By dividing the positioning system into independent cell measurements relative to a reference cell, the system reduces overall complexity while maintaining positioning accuracy through the aggregation of individual cell timing information.

The patent implements dynamics by making RTD reporting conditional and event-driven rather than continuous. The UE monitors for changes in timing synchronization offsets and triggers RTD value reporting only when actual changes are detected. This ensures positioning reliability by reporting whenever timing conditions change while reducing signaling overhead by avoiding redundant reports when no changes occur.

The patent applies self-service by enabling the UE to autonomously determine when RTD value reporting is necessary based on its own monitoring of timing synchronization offset changes. The UE independently assesses whether timing conditions have changed and triggers reporting accordingly, eliminating the need for continuous network requests and reducing overall signaling overhead while maintaining positioning reliability.
