Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If joint data transmission from multiple antenna panels is supported, then transmission rate is improved, but device complexity increases due to lack of standardization

Engineering Contradiction:
Improvetransmission rateVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the uplink data transmission by dividing data layers into different groups and assigning each group to specific antenna panels. This segmentation allows multiple panels to transmit simultaneously without requiring complex coordinated control, thereby improving transmission rate while managing device complexity through structured division of transmission tasks.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces dynamic selection of transmission manners (single-panel, multi-panel, or divided transmission) based on terminal capabilities and channel conditions. This dynamic approach allows the system to adapt between different transmission configurations, optimizing for high transmission rate when conditions permit while falling back to simpler single-panel transmission when complexity needs to be reduced.

Inventive Principle:
Principle #15Dynamics

2Productivity

If multiple antenna panels are used for simultaneous transmission, then transmission efficiency is improved, but power consumption increases

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidpower consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent enables dynamic switching between single-panel and multi-panel transmission modes based on terminal power status and channel conditions. When power consumption needs to be reduced, the system can switch to single-panel transmission; when transmission efficiency is prioritized and power is available, multi-panel simultaneous transmission is activated, providing adaptive optimization of the power-efficiency tradeoff.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent allows the terminal to selectively activate only the necessary number of antenna panels based on current transmission requirements rather than always using all available panels. This partial action approach enables the system to achieve sufficient transmission efficiency using fewer panels when appropriate, thereby reducing power consumption while maintaining adequate performance.

Inventive Principle:
Principle #16Partial or excessive action

3Ease of operation

If standardized transmission manners are established, then ease of operation is improved, but adaptability to different terminal capabilities is reduced

Engineering Contradiction:
Improveease of operationVSAvoidadaptability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent designs transmission manners that serve multiple functions and can be universally applied across different terminal types. The standardized transmission manners are formulated to work with various terminal capabilities by incorporating capability indication mechanisms, allowing the same standard to adapt to different hardware configurations while maintaining ease of operation through unified procedures.

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

Solution Approach 2:

The patent enables adaptation to different terminal capabilities by allowing changes in transmission parameters such as the number of antenna panels used, data layer allocation, and resource configuration. These parameter changes are controlled through capability indication and network configuration, allowing standardized procedures to be flexibly adjusted to match specific terminal capabilities without requiring separate standards for each device type.

Inventive Principle:
Principle #35Parameter changes
