Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently selecting the optimal network mode for positioning operations based on varying technologies and capabilities of user equipment, leading to suboptimal location estimation accuracy and efficiency.

User equipment (UE) analyzes positioning System Information Blocks (posSIBs) to select the most suitable network mode, considering available technologies such as LTE, FR1, and FR2, enabling precise network mode selection based on cell information and UE capabilities.
Engineering Contradictions & Design Principles
Engineering 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
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
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
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
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
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

AI summary
Techniques are provided for network mode selection based on positioning system information blocks (SIBs). An example method for measuring positioning reference signals with a user equipment includes receiving one or more system information blocks containing positioning reference signal information, determining band and frequency information for positioning reference signals based on the one or more system information blocks, determining at least one operational constraint for the user equipment, determining a network mode for the user equipment based at least on the band and frequency information and the at least one operational constraint, and measuring one or more positioning reference signals based at least in part on the network mode.
