UE Positioning Signal Priority for Sidelink and Uplink Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positioning methods in 5G wireless networks face challenges in efficiently handling collisions between UE-to-UE location reference signals and radio-network-interface signals, leading to conflicts in resource allocation and scheduling, which affect the accuracy and efficiency of mobile device location determination.
Innovation Solution
Implementing a priority mechanism in user equipment (UE) to resolve processing conflicts between UE-to-UE location reference signals and radio-network-interface signals, allowing for coordinated exchange and measurement of these signals based on a priority list, enabling simultaneous or separate resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If UE-to-UE location reference signals and radio-network-interface signals are exchanged simultaneously, then positioning accuracy is improved, but resource allocation conflicts occur
Solution Approach 1:
The patent segments the signal exchange process by introducing a priority mechanism that divides signals into different priority levels. The UE processes radio-network-interface signals and UE-to-UE location reference signals separately based on their priority assignments, preventing resource allocation conflicts while maintaining positioning accuracy through systematic signal handling.
2Productivity
If priority mechanism is implemented to resolve signal conflicts, then resource utilization is improved, but processing complexity increases
Solution Approach 1:
The patent applies preliminary action by establishing a priority list before signal exchange occurs. The UE is pre-configured with priority levels for different signal types, allowing it to automatically resolve conflicts without complex real-time processing. This preliminary structuring improves resource utilization while keeping processing complexity manageable through predefined rules.
3Reliability
If separate resource allocation is used for different signal types, then signal collision is reduced, but scheduling efficiency decreases
Solution Approach 1:
The patent introduces dynamics by making the resource allocation adaptive through priority-based scheduling. Instead of rigid separate allocation, the system dynamically assigns resources based on signal priority levels. High-priority signals receive preferred resources while lower-priority signals utilize remaining resources, reducing collisions while maintaining scheduling efficiency through flexible resource management.

AI summary
A UE includes: an interface comprising at least one of a receiver and a transmitter; a memory; and a processor, communicatively coupled to the interface and the memory, configured to: identify a processing conflict for an exchange of a first UE-to-UE location reference signal and an exchange of a first radio-network-interface signal; determine a priority of the exchange of the first UE-to-UE location reference signal and the exchange of the first radio-network-interface signal; and exchange, via the interface, one of the first UE-to-UE location reference signal or the first radio-network-interface signal according to the priority.
