Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If binary beam failure indicators are used, then the system is simple to implement, but the measurement precision and ability to distinguish varying wireless environments deteriorates
Solution Approach 1:
The patent changes the parameter of beam failure indicator from binary (0 or 1) to multi-level quantization values (e.g., 0, 1, 2, 3 or higher). This allows the indicator to represent different degrees of beam failure or channel quality levels, thereby improving measurement precision while maintaining reasonable system complexity through standardized quantization schemes.
2Measurement precision
If non-binary beam failure indicators with real number values are implemented, then the measurement precision improves, but the device complexity and processing requirements increase
Solution Approach 1:
The patent applies quantization to convert continuous real number measurements into discrete levels, and further applies mapping to transform these quantized values into standardized indicator formats. This reduces processing complexity while preserving the enhanced measurement precision of non-binary indicators.
Solution Approach 2:
The patent introduces intermediate processing layers (quantization and mapping functions) that mediate between the raw measurement data and the final beam failure indicator. These intermediaries simplify the complexity by providing structured transformation rules, making the system more manageable while maintaining precision.
3Loss of substance
If binary beam failure indicators are used, then the signaling overhead is reduced, but the loss of information about channel conditions increases
Solution Approach 1:
The patent changes the indicator parameter from binary to multi-level quantization, which efficiently packs more information into the same or slightly expanded signaling resources. The quantized levels represent different channel quality ranges, providing rich information while maintaining compact representation.
Solution Approach 2:
The patent adds an informational dimension by introducing multiple quantization levels rather than simple binary states. This dimensional expansion allows the indicator to convey gradient information about channel quality, reducing information loss while managing signaling overhead through efficient encoding.
