Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If extensive beam measurements are performed to improve beam management reliability, then measurement precision is improved, but reporting overhead and processing power requirements increase

Engineering Contradiction:

Improvebeam management reliabilityVSAvoidreporting overhead

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent changes the parameter representation by using differential values instead of absolute values for beam measurement reports. This parameter transformation reduces the number of bits required to represent measurement data while maintaining the necessary precision for beam management decisions, thereby reducing reporting overhead without compromising reliability

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent extracts only the essential information needed for beam management by reporting differential changes rather than complete measurement sets. This selective extraction of critical data elements reduces the volume of reporting data while preserving the key information required for reliable beam management

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 1:

The patent transforms the computational task by changing from processing and reporting absolute measurement values to processing and reporting differential values. This parameter change reduces the computational complexity of encoding and transmitting measurement data, thereby reducing processing power requirements while maintaining measurement precision for reliable beam management

Solution Approach 1:

The patent implements dynamic quantization by selecting from multiple quantization parameter sets based on current beam measurement conditions. This dynamic adaptation allows the system to use coarser quantization when precision requirements are lower and finer quantization when precision is critical, thereby reducing overall reporting overhead while maintaining necessary measurement precision

Inventive Principle:

Solution Approach 2:

The patent segments the quantization process into multiple parameter sets, each optimized for different measurement scenarios. This segmentation allows the system to apply appropriate quantization precision for different beam conditions, reducing overall data volume while preserving essential measurement accuracy through context-appropriate quantization selection

Inventive Principle:
