Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If self-carrier scheduling is used, then reliability is improved, but control signaling throughput is limited

Engineering Contradiction:

ImprovereliabilityVSAvoidcontrol signaling throughput

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent implements dynamic switching between self-carrier scheduling and cross-carrier scheduling modes based on real-time network conditions and traffic requirements. The base station can activate or deactivate cross-carrier scheduling dynamically, allowing the system to adapt its scheduling behavior to optimize both reliability and control signaling throughput under different operational scenarios.

Inventive Principle:

Principle #15Dynamics

2Productivity

If cross-carrier scheduling is used, then control signaling throughput is improved, but reliability deteriorates

Engineering Contradiction:

Improvecontrol signaling throughputVSAvoidreliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system dynamically adjusts the scheduling mode by activating or deactivating cross-carrier scheduling based on monitored network conditions. When reliability requirements are high, the system can deactivate cross-carrier scheduling to use self-carrier scheduling instead, thereby maintaining reliability while still allowing for high throughput when conditions permit.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If dynamic activation/deactivation of cross-carrier scheduling is implemented, then scheduling flexibility is improved, but device complexity increases

Engineering Contradiction:

Improvescheduling flexibilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The base station implements dynamic activation and deactivation of cross-carrier scheduling through control signaling, enabling flexible adaptation to changing network conditions. This dynamic mechanism allows the system to switch between scheduling modes as needed, providing high adaptability while managing device complexity through standardized control procedures.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system uses feedback mechanisms to monitor network conditions and scheduling performance, then adjusts the activation state of cross-carrier scheduling accordingly. This feedback-driven approach enables intelligent decision-making about when to activate or deactivate cross-carrier scheduling, optimizing the balance between flexibility and complexity.
