Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam failure recovery is performed with high transmission power to ensure timely recovery, then recovery speed and reliability are improved, but total transmission power threshold may be exceeded causing interference and system instability
Solution Approach 1:
The patent changes the parameter of transmission power by introducing priority information that dynamically adjusts the power allocation for beam failure recovery requests. The wireless device modifies transmission power parameters based on the priority level assigned to different recovery requests, ensuring high reliability for urgent recoveries while maintaining overall power threshold compliance.
2Adaptability or versatility
If multiple beam failure recovery requests are handled simultaneously with equal priority, then all recovery attempts are given equal opportunity, but power management becomes inefficient and recovery timeliness deteriorates
Solution Approach 1:
The patent segments the handling of beam failure recovery requests by introducing priority levels that divide recovery requests into different categories. This segmentation allows the system to process high-priority requests separately from low-priority ones, ensuring that critical recoveries are handled first while maintaining the ability to handle multiple requests simultaneously.
Solution Approach 2:
The patent changes the parameter of request handling by assigning priority values to different beam failure recovery requests. This parameter change enables the wireless device to adjust transmission power and processing order based on priority, improving recovery timeliness for critical requests while maintaining system flexibility to handle various types of recovery scenarios.
3Reliability
If transmission power is increased for beam failure recovery to overcome channel degradation, then recovery success rate improves, but power consumption increases and may exceed device limits
Solution Approach 1:
The patent changes the power consumption parameter by introducing priority-based power allocation. Instead of using fixed high power for all recovery attempts, the system adjusts transmission power parameters according to the priority information associated with each recovery request, achieving high success rates for critical recoveries while minimizing unnecessary power consumption for lower-priority scenarios.
