Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional beam refinement and tracking procedures are used for high mobility devices, then beam management can be performed, but latency increases and efficiency decreases

Engineering Contradiction:

Improvebeam tracking accuracyVSAvoidbeam reporting latency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by performing predictive beam measurements and preparing beam reports in advance before they are actually needed for communication. The UE measures reference signals and prepares beam indication information proactively, so that when beam refinement is required, the information is already available, thereby reducing latency without compromising tracking accuracy

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements skipping by reducing the number of sequential steps in the beam refinement process. Through joint beam reporting and indication mechanisms, multiple beam management operations are consolidated into fewer steps, allowing the system to rush through the beam refinement process quickly while maintaining reliability for high mobility devices

Inventive Principle:

Principle #21Skipping (Rushing through)

2Loss of information

If conventional beam reporting procedures are used, then beam information can be reported, but the number of steps increases and efficiency decreases

Engineering Contradiction:

Improvebeam information completenessVSAvoidbeam refinement efficiency

Core Design Contradiction:

Loss of informationVSProductivity

Solution Approach 1:

The patent applies merging by combining beam reporting and beam indication into a joint procedure. Instead of separate reporting and indication steps, the UE performs both functions in an integrated manner, consolidating multiple information transfer operations into a single efficient process that maintains complete beam information while improving refinement efficiency

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent implements universality by designing a joint beam reporting and indication mechanism that serves multiple functions simultaneously. The same procedure handles both reporting beam quality information and indicating preferred beams for refinement, making the system more versatile and efficient without losing information completeness

Inventive Principle:

Principle #6Universality (Multi-functionality)
