PRS Resource Set Reporting for 5G Positioning Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in the 5G NewRAT system, face challenges in accurately transmitting and receiving positioning information due to increased communication traffic and diverse use cases requiring high data rates, low latency, and massive connectivity, which affect the precision of location measurement.
Innovation Solution
A method and device for reporting positioning information in a wireless communication system that involves receiving and measuring multiple positioning reference signal (PRS) resource sets, obtaining positioning information, and reporting relevant data such as PRS resource identifiers, transmission and reception point IDs, reference signal received powers, and signal-to-noise ratios, to improve location measurement accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple PRS resource sets are measured and reported to improve positioning accuracy, then measurement precision improves, but device complexity and processing overhead increase
Solution Approach 1:
The patent segments positioning reference signals into multiple PRS resource sets, where each set contains multiple PRS resources. The terminal measures and reports positioning information for each resource set separately, allowing the system to achieve high positioning accuracy through multiple measurements while managing complexity through structured organization and selective reporting.
2Measurement precision
If comprehensive positioning information is reported for all PRS resources, then positioning accuracy improves, but information transmission overhead increases
Solution Approach 1:
The patent extracts and reports only the most relevant positioning information from multiple PRS resource sets. Specifically, the terminal identifies PRS resource sets with the highest RSRP or SINR values and reports positioning information selectively for these sets, rather than reporting all measurements. This reduces information overhead while maintaining positioning accuracy.
3Adaptability or versatility
If multiple PRS resources are measured to handle diverse 5G use cases, then adaptability improves, but measurement time and processing duration increase
Solution Approach 1:
The patent implements dynamic selection of PRS resource sets for measurement based on current system conditions and use case requirements. The terminal dynamically identifies and measures only the most relevant PRS resource sets (e.g., those with highest RSRP or SINR), allowing the system to adapt to diverse 5G use cases (eMBB, URLLC, mMTC) while minimizing measurement time and processing duration.
