Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple reference signals are transmitted in the same slot using different transmission spatial settings, then beam management efficiency is improved, but transmission reliability deteriorates due to potential interference and conflict

Engineering Contradiction:
Improvebeam management efficiencyVSAvoidtransmission reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent divides the slot into multiple subsets, where each subset contains reference signals with the same transmission spatial setting. This segmentation allows multiple reference signals to be transmitted in the same slot without interference, as signals in different subsets use different spatial settings. The first reference signal uses a first spatial setting while the second reference signal uses a second spatial setting, enabling efficient beam management while maintaining transmission reliability through structured organization.

Inventive Principle:
Principle #1Segmentation

2Area of stationary object

If reference signals are transmitted using multiple transmission spatial settings, then spatial coverage is improved, but signal interference increases

Engineering Contradiction:
Improvespatial coverageVSAvoidsignal interference
Core Design Contradiction:
Area of stationary objectVSObject-generated harmful factors

Solution Approach 1:

The patent segments reference signals into multiple subsets based on their transmission spatial settings. Each subset contains only reference signals with identical spatial settings, which eliminates interference between different spatial settings. This allows the system to cover multiple spatial directions simultaneously while preventing signal interference through careful organization of signals within subsets.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a subset structure as an intermediary organization layer between the reference signals and the transmission spatial settings. This intermediary structure mediates the relationship by grouping signals that can coexist without interference, allowing multiple spatial settings to operate simultaneously while managing the harmful effect of potential interference through structured separation.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If a set of slots with multiple transmission spatial settings is configured, then beam management capability is improved, but system complexity increases

Engineering Contradiction:
Improvebeam management capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the configuration into a clear structure where a set of slots is divided into multiple subsets, each subset corresponding to a specific transmission spatial setting. This segmentation makes the complex beam management capability more manageable and easier to implement, as the system can process and manage each subset independently while maintaining the overall beam management capability across multiple slots and spatial settings.

Inventive Principle:
Principle #1Segmentation
