Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If secondary component carriers are activated for data transmission, then data transmission capability is improved, but power consumption and resource utilization increase
Solution Approach 1:
The patent implements dynamic activation and deactivation of secondary component carriers based on real-time data transmission requirements. The network device sends activation/deactivation commands to the user equipment, allowing the system to adaptively adjust the number of active carriers, thereby improving data transmission capability when needed while reducing power consumption when transmission is not required.
Solution Approach 2:
The system changes the operational state parameter of component carriers between active and inactive states. By controlling the activation status of secondary component carriers through network device commands, the system optimizes the balance between data transmission performance and power consumption according to varying traffic conditions.
2Productivity
If secondary component carriers are activated continuously, then data transmission efficiency is improved, but spectrum resource utilization worsens due to unnecessary transmission
Solution Approach 1:
The network device provides feedback control by monitoring data transmission requirements and sending activation or deactivation commands for secondary component carriers. This feedback mechanism ensures that carriers are activated only when data transmission is needed and deactivated when not needed, preventing spectrum resource waste while maintaining transmission efficiency.
Solution Approach 2:
The system performs preliminary activation of secondary component carriers based on predicted or scheduled data transmission requirements. By activating carriers in advance when needed and deactivating them when not needed, the system optimizes spectrum utilization without compromising transmission efficiency.
3Quantity of substance
If multiple component carriers are configured, then spectrum resource utilization is improved, but device complexity increases
Solution Approach 1:
The patent divides the spectrum resources into multiple component carriers, including primary and secondary carriers. This segmentation allows the system to utilize multiple carriers for data transmission, increasing spectrum resource utilization while managing complexity through clear separation of carrier functions and network-controlled activation/deactivation.
