Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all bandwidth parts maintain full signaling functionality, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent applies local quality by differentiating signaling behavior across different bandwidth parts. Active bandwidth parts maintain full signaling functionality (PDCCH monitoring, PUCCH transmission) while dormant bandwidth parts suppress these functions. This localized differentiation allows the system to maintain reliability where needed while reducing power consumption in less critical bandwidth parts.
Solution Approach 2:
The patent implements dynamics by enabling flexible switching between active and dormant states for bandwidth parts. The network can dynamically activate or deactivate dormant bandwidth parts based on traffic conditions, allowing the system to adapt power consumption levels while maintaining communication reliability when required.
2Speed
If secondary cells remain active for fast data transmission, then data transmission speed is improved, but network resource utilization deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the bandwidth into multiple bandwidth parts with different operational states. Instead of treating the entire secondary cell as either active or dormant, the system segments it into active bandwidth parts (for fast transmission) and dormant bandwidth parts (for resource conservation), allowing simultaneous optimization of speed and resource utilization.
Solution Approach 2:
The patent implements partial action by maintaining full signaling functionality only in active bandwidth parts while suppressing it in dormant bandwidth parts. This partial activation allows the system to achieve fast data transmission where needed without committing network resources across the entire secondary cell, thereby improving overall resource utilization.
3Use of energy by moving object
If signaling is suppressed on dormant bandwidth parts, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring dormant bandwidth parts with suppressed signaling functionality through RRC signaling. The UE is provided with configuration information indicating which bandwidth parts are dormant and which signaling types should be suppressed in advance, eliminating the need for complex real-time decisions and reducing device complexity during operation.
