Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If SCell deactivation timer uses fixed value, then device complexity is reduced, but resource usage efficiency deteriorates
Solution Approach 1:
The patent applies dynamics by changing the timer value from a fixed static parameter to a dynamic parameter that can be adjusted based on network conditions. The network can update the SCell deactivation timer value through MAC CE or DCI signaling, allowing the system to adapt timer duration to current traffic patterns and energy saving requirements, thereby improving resource usage efficiency without significantly increasing device complexity.
Solution Approach 2:
The patent implements parameter changes by modifying the timer value parameter based on different operational scenarios. The network can dynamically adjust the sCellDeactivationTimer parameter through higher layer signaling or physical layer indications, enabling flexible control over SCell activation duration to optimize both energy efficiency and resource utilization.
2Use of energy by stationary object
If SCell is deactivated frequently for energy saving, then power consumption is reduced, but resource usage efficiency deteriorates
Solution Approach 1:
The patent uses dynamics to adjust the SCell deactivation behavior based on real-time network conditions. By dynamically updating the timer value through MAC CE or DCI signaling, the system can extend SCell activation duration when traffic requires it, or deactivate sooner when energy saving is prioritized, achieving optimal balance between power consumption and resource efficiency.
Solution Approach 2:
The patent applies parameter changes by modifying the deactivation timer parameter in response to different operational states. The network can signal parameter updates to change when SCell deactivation occurs, allowing flexible control over the trade-off between energy saving and maintaining resource availability for potential data transmissions.
3Productivity
If SCell deactivation timer value is updated dynamically, then resource usage efficiency is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary mechanism through MAC CE or DCI signaling to convey timer value updates from the network to the UE. This intermediary approach allows the network to control timer adjustments without requiring complex autonomous decision-making at the UE side, thereby improving resource efficiency while limiting the increase in device complexity to processing standardized signaling messages.
