Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complete sensing is performed for resource selection, then resource allocation reliability is improved, but sensing time and complexity increase

Engineering Contradiction:

Improveresource allocation reliabilityVSAvoidsensing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies partial sensing by selecting only specific time units (e.g., every k-th time unit or time units with high probability of resource allocation) for sensing instead of sensing all time units. This reduces the sensing time and complexity while maintaining sufficient reliability for resource selection in D2D/V2X communication.

Inventive Principle:

Principle #16Partial or excessive action

2Productivity

If partial sensing is implemented for periodic services, then sensing efficiency is improved, but resource selection flexibility for non-periodic services deteriorates

Engineering Contradiction:

Improvesensing efficiencyVSAvoidresource selection flexibility

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent introduces dynamic adaptability by allowing the terminal to flexibly select time units for sensing based on service characteristics. For non-periodic services, the terminal can adaptively choose to sense time units where resource allocation is more likely to occur, thereby maintaining both sensing efficiency and resource selection flexibility through dynamic adjustment of sensing strategy.

Inventive Principle:

Principle #15Dynamics

3Speed

If sensing is performed only before time n, then resource selection speed is improved, but resource allocation accuracy deteriorates

Engineering Contradiction:

Improveresource selection speedVSAvoidresource allocation accuracy

Core Design Contradiction:

SpeedVSMeasurement precision

Solution Approach 1:

The patent performs preliminary sensing before time n to identify potential resource allocation time units, then focuses sensing efforts on these pre-identified time units. This preliminary action enables faster resource selection while maintaining accuracy by concentrating sensing resources on the most relevant time units where resource allocation is likely to occur.

Inventive Principle:

Principle #10Preliminary action
