Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-carrier channel detection is implemented in LAA systems, then the probability of accessing unauthorized carriers is improved, but the device complexity increases due to multiple channel detection processes
Solution Approach 1:
The patent segments the channel detection process into two distinct parts: a first channel detection process for primary channels and a second channel detection process for secondary channels. This segmentation allows each detection process to be optimized independently, improving overall access probability while managing complexity through structured division of detection tasks.
Solution Approach 2:
The patent implements dynamic channel detection by continuously performing the first channel detection process on primary channels and the second channel detection process on secondary channels. This dynamic approach adapts to changing channel conditions, improving access probability while managing complexity through selective and continuous monitoring strategies.
2Reliability
If continuous channel detection is performed on all carriers, then the access probability is improved, but the power consumption increases
Solution Approach 1:
The patent segments carriers into primary channels and secondary channels, applying different detection strategies to each segment. Primary channels undergo continuous first channel detection processes, while secondary channels undergo second channel detection processes, optimizing the balance between access probability and power consumption through differentiated monitoring.
Solution Approach 2:
The patent applies different detection qualities and intensities to different channel types. Primary channels receive more intensive continuous detection resources, while secondary channels receive optimized detection resources tailored to their specific access requirements, achieving local optimization of power consumption versus access probability.
