Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional base station-controlled precoding is used in 4G LTE, then uplink transmission is simple and controlled, but it cannot adapt to diverse 5G NR antenna configurations and increases signaling overhead

Engineering Contradiction:

Improveadaptability to antenna configurationsVSAvoidprecoding control complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent inverts the conventional control relationship by allowing the terminal to autonomously determine uplink transmission parameters (including precoding) based on pre-configured codebooks, rather than having the base station control all precoding decisions. This inversion reduces signaling overhead while maintaining adaptability to diverse antenna configurations.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The base station performs preliminary configuration by providing the terminal with codebook information and transmission parameter settings in advance. The terminal then uses these pre-configured parameters to autonomously determine uplink transmission settings, reducing the need for real-time base station control and signaling.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If terminal performs autonomous precoding in 5G NR, then flexibility and adaptability to diverse antenna designs improve, but determining appropriate transmission parameters becomes more difficult

Engineering Contradiction:

Improveflexibility in precoding selectionVSAvoidparameter determination difficulty

Core Design Contradiction:

Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent introduces codebooks as intermediary structures that bridge the gap between terminal autonomy and base station control. The codebooks contain pre-defined transmission parameters and precoding matrices that the terminal can select autonomously, making parameter determination easier while maintaining flexibility for diverse antenna configurations.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent enables dynamic parameter changes by allowing the terminal to select different codebooks and transmission parameters based on channel conditions and antenna configurations. The base station can update codebook configurations through signaling, enabling adaptive parameter changes without requiring complex real-time control.

Inventive Principle:

Principle #35Parameter changes

3Ease of manufacture

If simple codebook design is used for uplink transmission, then implementation is easier, but it cannot accommodate complicated antenna designs with multiple panels and elements

Engineering Contradiction:

Improvecodebook design simplicityVSAvoidsupport for antenna configurations

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent segments the codebook design into multiple hierarchical levels: base codebooks for different antenna panels, element-specific configurations, and composite codebooks for MIMO transmissions. This segmentation allows simple individual codebook designs to be combined to support complicated overall antenna configurations with multiple panels and elements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent designs universal codebook structures that can serve multiple functions: supporting different antenna configurations (single-panel, multi-panel), different MIMO modes (single-user, multi-user), and different transmission scenarios. This multi-functionality allows a single codebook framework to accommodate complicated antenna designs while maintaining design simplicity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
