Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single channel state information report configuration is used, then the device complexity is reduced, but the measurement precision and adaptability of CSI reporting deteriorate

Engineering Contradiction:
ImproveCSI report configuration managementVSAvoidCSI reporting accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent divides the single CSI report configuration into multiple configurations (first and second CSI report configurations), each with different resolution levels. This segmentation allows the system to maintain multiple CSI reporting options without requiring a complete redesign of the CSI management architecture, thus improving measurement precision while controlling device complexity through modular configuration management.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces dynamic switching between different CSI report configurations based on channel conditions and performance requirements. The network can dynamically select which CSI report configuration to use, enabling the system to adapt to varying measurement precision needs while maintaining manageable device complexity through flexible configuration selection rather than fixed single-configuration designs.

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If high-resolution CSI reporting is always used, then the measurement precision is improved, but the loss of energy and productivity decreases due to increased processing overhead

Engineering Contradiction:
ImproveCSI reporting resolutionVSAvoidProcessing energy consumption
Core Design Contradiction:
Measurement precisionVSLoss of energy

Solution Approach 1:

The patent enables dynamic adjustment of CSI reporting resolution by switching between different CSI report configurations based on channel conditions and network requirements. When high precision is needed, the system uses high-resolution configurations; when energy efficiency is prioritized, lower-resolution configurations are selected, thus optimizing the trade-off between measurement precision and energy consumption.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the resolution parameter of CSI reporting by selecting different configurations with varying resolution levels. This parameter change allows the system to adapt CSI reporting precision to actual needs, avoiding unnecessary high-resolution reporting when it is not required, thereby reducing processing energy consumption while maintaining adequate measurement precision when needed.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple channel state information report configurations are maintained, then the adaptability is improved, but the device complexity and difficulty of operation increases

Engineering Contradiction:
ImproveCSI configuration flexibilityVSAvoidConfiguration management complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent segments multiple CSI report configurations into distinct, well-defined structures (first and second configurations with different resolution characteristics). This segmentation provides clarity in managing multiple configurations, making it easier to operate and select appropriate configurations rather than dealing with an undifferentiated set of complex options.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent designs the multiple CSI report configurations to serve universal purposes across different operating conditions. Each configuration is designed with a specific resolution level that can be universally applied in appropriate scenarios, providing a systematic approach to configuration selection that simplifies operation while maintaining high adaptability to various channel conditions and network requirements.

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

4Productivity

If dynamic switching between CSI configurations is implemented, then the productivity and communication performance is improved, but the device complexity and loss of time for configuration management increases

Engineering Contradiction:
ImproveResource allocation efficiencyVSAvoidConfiguration switching time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent prepares multiple CSI report configurations in advance, with each configuration pre-defined for specific resolution requirements and channel conditions. This preliminary preparation eliminates the need for complex real-time configuration creation during switching, reducing the time loss associated with configuration management while enabling efficient dynamic switching to optimize productivity and resource allocation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements dynamic switching between pre-prepared CSI configurations based on real-time channel conditions and network state. This dynamic approach allows the system to quickly adapt to changing conditions and optimize resource allocation without requiring complex real-time configuration synthesis, thus improving productivity while minimizing the time loss for configuration management through efficient pre-prepared configuration selection.

Inventive Principle:
Principle #15Dynamics
