Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS service is used for location-based service, then location accuracy is improved, but power consumption increases and it cannot be used in indoor environments
Solution Approach 1:
The patent introduces beamforming technology as an intermediary mechanism between the communication system and location determination. By using directional beams and beam book information, the system can determine device location through signal characteristics without requiring GPS satellites, thus achieving indoor location capability while managing power consumption through optimized beam management
2Measurement precision
If WLAN scanning is performed frequently to improve location accuracy and speed, then location estimation performance is improved, but power consumption increases
Solution Approach 1:
The system enables self-service location determination by utilizing existing beamforming communication infrastructure. The base station and electronic device use beam book information and antenna information to determine location without requiring separate WLAN scanning operations, thereby achieving location accuracy without the additional power consumption of frequent scanning
Solution Approach 2:
The beamforming communication system serves dual purposes: maintaining communication connectivity and determining device location. The same antenna information and beam book data used for beam management also provide location information, eliminating the need for separate location-specific scanning operations
3Productivity
If narrow beam width is used for efficient high frequency transmission, then transmission efficiency is improved, but difficulty in obtaining optimal beam pair increases
Solution Approach 1:
The patent implements preliminary action by pre-establishing beam book information that contains antenna information for each beam index. This pre-configured data structure enables the system to quickly identify optimal beam pairs without extensive real-time adjustments, reducing the complexity of beam management while maintaining narrow beam efficiency
Solution Approach 2:
The system uses parameter changes by organizing beam information with specific parameters (beam index, antenna information, coverage area). This structured parameter management allows efficient selection and adjustment of beam pairs based on device location and communication requirements, simplifying the overall beam management process
