5G Terminal Positioning QoS-Based Assistance Data Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 5G positioning methods incur high resource overheads and waste due to uniform assignment of positioning assistance data to all terminal devices, leading to inefficient resource utilization.
Innovation Solution
A method and apparatus that consider the positioning quality of service (QoS) information of each terminal device to tailor positioning assistance data, assigning unique data based on individual QoS, thereby reducing resource overheads and waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If uniform positioning assistance data is assigned to all terminal devices, then positioning precision can be ensured for all devices, but system resource overheads increase and resources are wasted
Solution Approach 1:
The patent applies local quality by customizing positioning assistance data according to each terminal device's specific QoS requirements. Instead of uniform assignment, the network device determines different assistance data (including time-frequency resource configuration, period, and muting mechanism parameters) based on individual terminal characteristics, ensuring each device receives optimized data tailored to its positioning precision and latency needs while reducing overall system resource consumption.
2Ease of operation
If uniform positioning assistance data is assigned to all terminal devices, then implementation simplicity is maintained, but resource utilization efficiency decreases
Solution Approach 1:
The patent implements dynamics by making the positioning assistance data assignment adaptive rather than static. The network device dynamically determines assistance data parameters based on real-time QoS information from each terminal device, allowing the system to adjust resource allocation according to actual positioning requirements. This dynamic approach improves resource utilization efficiency while maintaining operational simplicity through automated QoS-based decision-making.
