Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If wireless access technologies are multiplexed by definition of the same radio resources, then resource allocation is simplified, but it becomes difficult to multiplex wireless access technologies with different resource definitions

Engineering Contradiction:
Improveresource allocation complexityVSAvoidmultiplexing capability of different wireless access technologies
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent changes the resource definition parameters by introducing a new parameter set that includes a parameter indicating the start position of radio resources and a parameter indicating the length of radio resources. This allows different wireless access technologies to be multiplexed by varying these parameters while maintaining a unified resource allocation framework, thus resolving the contradiction between simplified resource allocation and multiplexing capability.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If resource definitions are made flexible to accommodate different use cases, then adaptability improves, but frequency use efficiency deteriorates due to difficulty in multiplexing

Engineering Contradiction:
Improveflexibility of wireless frame parametersVSAvoidfrequency use efficiency
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent creates a universal resource allocation framework that can handle both flexible parameter definitions and efficient multiplexing. By defining a unified parameter set that can accommodate different wireless access technologies and use cases, the system achieves both adaptability and frequency use efficiency through a single multi-functional resource allocation mechanism.

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