Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beamforming and handover processes are managed using existing wireless communication networks, then network coverage and connectivity are maintained, but radio link quality is suboptimal and energy consumption is increased
Solution Approach 1:
The patent implements dynamic adjustment of beamforming strategies and handover thresholds based on real-time radio link quality measurements. The system continuously monitors link quality metrics and adapts beamforming parameters and handover decisions dynamically, allowing the network to optimize performance and energy consumption according to current conditions rather than using static configurations.
Solution Approach 2:
The system changes key parameters including beamforming configuration, handover thresholds, and power saving operation settings based on measured radio link quality. By adjusting these parameters dynamically, the system improves reliability when link quality is poor while reducing energy consumption when conditions are favorable, resolving the contradiction between these two objectives.
2Reliability
If dynamic adjustment of beamforming and handover strategies is implemented, then radio link quality is improved, but system complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where radio link quality is continuously measured and used to adjust beamforming and handover strategies. The system monitors link quality metrics and feeds this information back to control entities that adjust parameters accordingly, creating a closed-loop system that improves reliability through adaptive control while managing complexity through structured feedback processing.
Solution Approach 2:
The system performs self-adjustment of beamforming and handover parameters based on autonomous measurement of radio link quality. By enabling the system to monitor and adjust its own parameters without external intervention, it improves reliability through adaptive optimization while reducing the operational complexity of manual configuration and management.
3Use of energy by moving object
If power saving operations like C-DRX and U-DRX are integrated, then energy efficiency is enhanced, but responsiveness to radio link quality changes may be reduced
Solution Approach 1:
The patent dynamically adjusts power saving operation parameters including DRX cycle lengths and activation thresholds based on radio link quality measurements. When link quality is good, the system can use longer DRX cycles for greater energy savings. When link quality deteriorates, the system reduces DRX cycle lengths or activates more frequent monitoring to maintain responsiveness, thus balancing energy efficiency with response speed adaptively.
