Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If reference signal configuration is fixed in existing millimeter wave communication systems, then system complexity is reduced, but beam measurement flexibility is limited and reference signal utilization rate decreases

Engineering Contradiction:
Improvebeam measurement flexibilityVSAvoidreference signal configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by making the reference signal configuration adaptable and flexible rather than fixed. The system dynamically adjusts reference signal resources based on actual beam measurement needs, allowing the configuration to change according to different measurement scenarios and requirements, thereby improving beam measurement flexibility without excessive complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of reference signal configuration from fixed to flexible by introducing configurable parameters such as channel characteristic requirements. These parameters can be adjusted to match different beam measurement scenarios, enabling the system to adapt to varying needs while maintaining manageable complexity through standardized parameter sets

Inventive Principle:
Principle #35Parameter changes

2Productivity

If reference signal is dedicated to single user in existing systems, then measurement accuracy is improved, but reference signal utilization rate and spectrum efficiency are reduced

Engineering Contradiction:
Improvespectrum efficiencyVSAvoidbeam measurement accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent applies universality by enabling reference signals to serve multiple users simultaneously. The same reference signal resources can be shared across different users and beam measurement scenarios, increasing the utilization rate and spectrum efficiency while maintaining adequate measurement accuracy through flexible configuration options

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent segments reference signal resources into different types or categories that can be selectively allocated. By dividing reference signal resources into different configurations (e.g., different channel characteristic requirements), the system can allocate appropriate resources to different users based on their specific needs, balancing utilization efficiency with measurement accuracy

Inventive Principle:
Principle #1Segmentation
