Engineering Contradiction Analysis
1Reliability
If beam-specific channel sensing failure detection and reporting is implemented, then channel sensing failure detection effectiveness is improved, but device complexity increases due to configuring and managing counters and timers for each beam
Solution Approach 1:
The patent divides the channel sensing failure detection mechanism into beam-specific components, where each beam has its own counter and timer configured independently. This segmentation allows the system to track and detect failures on a per-beam basis, improving detection effectiveness while maintaining manageable complexity through modular organization of detection resources.
Solution Approach 2:
The patent applies local quality by configuring detection parameters (counters and timers) specifically for each beam according to its individual characteristics and requirements. Rather than using a uniform detection mechanism across all beams, the system tailors the detection sensitivity and thresholds to local beam conditions, optimizing failure detection for each specific beam while avoiding unnecessary complexity in beams that don't require it.
2Reliability
If persistent failures are declared based on configured thresholds with counters and timers, then reliability of failure detection is improved, but loss of time increases due to monitoring and threshold evaluation processes
Solution Approach 1:
The patent configures counters and timers in advance with pre-defined thresholds before channel sensing operations begin. This preliminary configuration allows the system to immediately evaluate sensing results against established criteria without requiring complex real-time analysis, reducing the time needed to declare persistent failures while maintaining reliable detection through pre-calculation of failure thresholds.
Solution Approach 2:
The patent implements a feedback mechanism where channel sensing results are continuously monitored and compared against configured thresholds, with automatic declaration of persistent failures when thresholds are exceeded. This closed-loop feedback system efficiently detects failures by continuously evaluating sensing outcomes against predefined criteria, reducing detection latency through automated threshold-based decision making rather than manual or complex algorithmic analysis.
