Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, particularly in new radio (NR) environments, face challenges in providing robust positioning and location services due to limitations in reporting radio signaling measurements, which are inadequate for increasing data traffic and complex communication environments.
Innovation Solution
The implementation of multi-level configuration and reporting techniques for positioning in NR systems, where user equipment (UE) receives positioning reference signal (PRS) transmissions and determines report parameters based on measurements, allowing for flexible reporting levels to improve positioning accuracy and reduce signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional single-level reporting is used for positioning measurements, then the signaling overhead is reduced, but the positioning accuracy and reporting robustness deteriorate
Solution Approach 1:
The patent divides the positioning reporting system into multiple hierarchical levels (resource level, set level, setting level, and base station level), where each level handles specific reporting tasks. This segmentation allows the system to provide detailed positioning information when needed while maintaining simplified reporting in other scenarios, thus improving positioning accuracy without overwhelming complexity.
Solution Approach 2:
The patent introduces dynamic reporting levels that can be flexibly configured and switched based on positioning requirements, network conditions, and UE capabilities. The network can dynamically select which reporting level to use, enabling the system to adapt between detailed and simplified reporting modes, thereby improving positioning accuracy when required while managing complexity through conditional activation.
2Measurement precision
If detailed positioning reports are transmitted at all levels, then positioning accuracy improves, but signaling overhead increases
Solution Approach 1:
The hierarchical segmentation of reporting levels enables selective transmission of detailed positioning information. Instead of transmitting full detailed reports at all levels, the system transmits comprehensive reports only at necessary levels (e.g., specific base station levels where positioning is required) while using aggregated or simplified reports at other levels, thus maintaining positioning accuracy where needed while reducing overall signaling overhead.
Solution Approach 2:
Different reporting levels transmit different quantities and types of information based on local requirements. The resource level may transmit minimal information, while specific base station levels transmit detailed positioning data. This local quality approach ensures that detailed positioning reports are transmitted only where and when needed, improving positioning accuracy at specific locations while minimizing overall signaling overhead across the network.
3Reliability
If multi-level reporting configuration is implemented, then reporting robustness improves, but device complexity increases
Solution Approach 1:
The patent designs the multi-level reporting framework with universal structures and procedures that can be applied across different reporting scenarios and levels. Common configuration parameters, reporting formats, and processing procedures are standardized across all levels, allowing the complex multi-level system to be managed through universal principles and reducing the effective complexity through pattern recognition and standardized handling.
Solution Approach 2:
The system includes automatic capability indication mechanisms where UEs self-report their positioning capabilities and the network automatically determines the appropriate reporting levels and configurations. This self-service approach reduces configuration complexity by eliminating manual setup and allowing the system to automatically adapt to UE capabilities, thereby improving reporting robustness while managing complexity through automation.

AI summary
This disclosure provides methods, devices, and systems for multi-level configuration and reporting for positioning in new radio (NR) wireless communications systems. In some wireless communications systems, a network entity may determine a position or location of a supported user equipment (UE) using radio access network information. The information may be associated with UE-assisted positioning techniques, such as a positioning reference signal (PRS) transmission by the base station and reporting of radio signaling measurements by the UE. The UE may support a multi-level configuration for reporting the radio signaling measurements, including determined report quantities on one or more of a resource level, a set level, or a setting level for the PRS transmission, or generally for the network entity. The described techniques may improve robustness associated with the reporting and, in some examples, reduce signaling overhead associated with determining a positioning and location of the UE.
