Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems rely heavily on base station positioning, which limits positioning accuracy and coverage, especially in sparse network layouts and outside network coverage areas, necessitating improved methods for sidelink communication-based positioning.
Innovation Solution
A method where user equipment (UE) determines and transmits/receives sidelink positioning signals based on specific conditions and resource allocation, allowing flexible and accurate positioning without relying solely on base station control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If base station positioning methods are used, then system simplicity is maintained, but positioning accuracy and coverage are limited
Solution Approach 1:
The patent enables user equipment to perform positioning measurements autonomously using sidelink signals from other UEs, without requiring base station control. The UE independently determines positioning based on received signal characteristics, achieving self-service positioning that improves accuracy while maintaining system simplicity.
Solution Approach 2:
The patent introduces sidelink positioning signals as an intermediary mechanism between UEs for direct positioning measurements. These signals act as mediators that carry positioning information between devices, enabling accurate positioning without base station involvement and expanding coverage to areas without network infrastructure.
2Area of stationary object
If base station-dependent positioning is used, then network control is maintained, but coverage is limited to network areas
Solution Approach 1:
The patent enables user equipment to perform positioning measurements autonomously using sidelink signals from other UEs, without requiring base station control. The UE independently determines positioning based on received signal characteristics, achieving self-service positioning that improves accuracy while maintaining system simplicity.
Solution Approach 2:
The patent segments the positioning function from base station control, allowing UE to independently perform positioning measurements using sidelink signals. This segmentation enables positioning operations to occur autonomously at the device level, expanding coverage to areas without network infrastructure while maintaining network control where available.
3Measurement precision
If UE independently manages sidelink signal transmission, then positioning accuracy improves, but resource allocation complexity increases
Solution Approach 1:
The patent implements dynamic resource allocation for sidelink positioning signals, where resource selection adapts based on channel conditions, UE mobility, and positioning requirements. This dynamic approach optimizes resource utilization while maintaining positioning accuracy, balancing the trade-off between performance and management complexity through flexible, condition-based resource selection.
