Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional radio access technology is used, then system complexity is kept manageable, but positioning accuracy and measurement precision are insufficient for 5G requirements
Solution Approach 1:
The patent segments the positioning measurement process into distinct phases: beam identification, reference signal reception, and position calculation. The terminal device measures reference signals from multiple base stations independently, then combines measurements to determine position, breaking down the complex positioning task into manageable segments that improve accuracy without overwhelming system complexity
Solution Approach 2:
The patent employs universal reference signals that serve multiple functions: channel estimation, beam management, and positioning measurement. The same reference signal infrastructure used for conventional communication also enables precise positioning, eliminating the need for separate dedicated positioning hardware and reducing overall system complexity while maintaining high measurement precision
2Measurement precision
If beamforming configuration is implemented for position measurement, then positioning accuracy is improved, but information transmission overhead increases
Solution Approach 1:
The patent merges position measurement information with existing uplink control information channels. The terminal device combines beam identification results and position measurement data into a unified report that is transmitted using existing signaling resources, thereby improving positioning accuracy without significantly increasing overall information overhead
Solution Approach 2:
The patent implements partial reporting where the terminal device transmits position measurement information only when measurement accuracy thresholds are met or when position updates are necessary. This selective transmission approach maintains high positioning accuracy while reducing redundant information overhead in scenarios where precise positioning is not required
