VSEngineering Contradiction Analysis

1Ease of operation

If the UE uses a default network mode for positioning operations, then the positioning process can be initiated without complex selection logic, but the location estimation accuracy and efficiency deteriorate due to suboptimal network mode selection

Engineering Contradiction:
Improvepositioning operation initiationVSAvoidlocation estimation accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The UE performs preliminary analysis of positioning SIBs to determine the optimal network mode before conducting positioning operations. This advance preparation allows the system to select the most suitable network mode (LTE, FR1, or FR2) based on available positioning reference signals and cell information, thereby improving location estimation accuracy without adding complexity during the actual positioning execution phase

2Measurement precision

If the UE analyzes positioning SIBs to select the optimal network mode, then location estimation accuracy is improved, but the device complexity increases due to additional analysis and selection logic

Engineering Contradiction:

Solution Approach 1:

The network mode selection process is segmented into distinct evaluation criteria: analyzing available positioning reference signals, identifying cell information from positioning SIBs, and selecting network modes based on specific conditions. This segmentation breaks down the complex selection logic into manageable, systematic steps that improve accuracy while maintaining operational clarity

Inventive Principle:

Solution Approach 2:

The network mode selection is designed to be dynamic and adaptive, allowing the UE to adjust its operating mode based on real-time analysis of positioning SIBs and available reference signals. The system can transition between LTE, FR1, and FR2 modes as conditions change, optimizing performance without requiring permanent complex configuration

Inventive Principle:

3Adaptability or versatility

If the UE operates in multiple network modes (LTE, FR1, FR2) for positioning, then adaptability to different wireless technologies is improved, but the difficulty of detecting and measuring positioning reference signals increases

Engineering Contradiction:

Solution Approach 1:

The UE applies local quality optimization by selecting the specific network mode (LTE, FR1, or FR2) that provides the best positioning conditions for the current location and environment. Rather than uniformly processing all available modes, the system identifies and focuses on the optimal mode based on local conditions such as signal availability and cell information, thereby reducing measurement complexity while maintaining high adaptability
