Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If access-stratum configuration parameters are configured to terminals in sidelink relay scenario, then relay communication can be normally performed, but the configuration method is unclear

Engineering Contradiction:

Improverelay communication normal operationVSAvoidparameter configuration clarity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a network device as an intermediary to configure access-stratum parameters to terminals. The network device receives configuration information from a first terminal and uses it to configure a second terminal, thereby clarifying the configuration process and enabling reliable relay communication without direct terminal-to-terminal configuration complexity

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The configuration process is segmented into distinct roles: a first terminal generates configuration information, a network device receives and processes it, and then configures the second terminal. This segmentation clarifies the previously unclear configuration method by dividing the task into manageable steps with clear responsibility boundaries

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If access-stratum configuration parameters are transmitted between terminals, then service processing is enabled, but configuration complexity increases

Engineering Contradiction:

Improveservice processing capabilityVSAvoidconfiguration process complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The network device serves as an intermediary that simplifies the configuration process. Instead of terminals directly exchanging complex configuration parameters, the network device receives configuration information from the first terminal and automatically configures the second terminal, reducing the apparent complexity for individual terminals while maintaining full service processing capability

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The first terminal autonomously generates the access-stratum configuration information based on its own parameters and requirements. This self-service approach enables the terminal to adaptively configure itself and the relay terminal without manual intervention, maintaining versatility while managing complexity through automation

Inventive Principle:

Principle #25Self-service
