Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If feedback reports are transmitted with complete details for each beam measurement, then measurement precision and reliability are improved, but signaling overhead increases and beam switching speed decreases
Solution Approach 1:
The patent extracts only the essential feedback information (beam measurement results and associated metadata) from complete measurement reports, transmitting only what is needed for beam switching decisions rather than all raw measurement data, thereby reducing signaling overhead while maintaining measurement precision
Solution Approach 2:
The patent uses feedback report identities as references or copies that point to stored beam measurement data, allowing the receiver to retrieve complete measurement information without transmitting the full data again, thus reducing signaling overhead while preserving measurement precision
2Reliability
If extensive feedback signaling is used to ensure reliable beam switching, then beam switching reliability is improved, but beam switching speed decreases and communication lags increase
Solution Approach 1:
The patent performs beam measurements and stores feedback report identities in advance, so that when beam switching is needed, the system can quickly retrieve and process pre-prepared feedback information rather than performing measurements in real-time, thereby maintaining reliability while improving switching speed
Solution Approach 2:
The patent implements efficient feedback mechanisms using compact feedback report identities that provide sufficient information for reliable beam switching decisions without requiring extensive signaling, enabling fast and reliable beam transitions
3Adaptability or versatility
If beam switching is performed frequently to track user movement, then adaptability to user movement is improved, but signaling overhead accumulates and system resources are consumed
Solution Approach 1:
The patent extracts only essential feedback information for each beam measurement, transmitting minimal necessary data (feedback report identities and key parameters) rather than complete measurement reports, thereby enabling frequent beam switching to track user movement while controlling signaling overhead accumulation
Solution Approach 2:
The patent uses feedback report identities that serve multiple functions: identifying beam measurements, referencing stored data, and enabling quick switching decisions, thereby reducing the total quantity of signaling needed while maintaining high adaptability to user movement
