Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If base station operates in high performance mode to support increasing wireless data traffic demand, then network performance is improved, but energy consumption increases
Solution Approach 1:
The base station dynamically switches between normal operation mode and energy saving mode based on traffic conditions. The operation start point indication enables the UE to understand when the BS will transition modes, allowing dynamic adaptation of both BS and UE operations to current traffic demands, thus improving energy efficiency without permanently sacrificing network performance
Solution Approach 2:
The energy saving mode operates periodically with defined start and end points. The BS transitions to energy saving mode during low-traffic periods and returns to normal mode when traffic increases, creating a periodic operation pattern that balances energy consumption with network performance requirements over time
2Use of energy by moving object
If base station transitions to energy saving mode to reduce energy consumption, then energy efficiency is improved, but communication efficiency may deteriorate
Solution Approach 1:
The base station provides advance notification to the UE about the operation start point of energy saving mode through indication information. This preliminary action allows the UE to prepare for the mode transition by completing pending transmissions or switching to monitoring modes that maintain connectivity with reduced power consumption, thus preventing communication efficiency deterioration
Solution Approach 2:
The system implements feedback mechanisms where the UE reports its status and the BS adjusts energy saving mode timing based on UE responses. The operation start point indication creates a feedback loop that ensures both BS and UE are synchronized, maintaining communication efficiency even during energy saving operations
3Adaptability or versatility
If base station provides detailed energy saving mode information to user equipment, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent extracts only the essential energy saving mode information (operation start point, mode type) and transmits it to the UE, omitting unnecessary detailed parameters. This selective extraction provides sufficient adaptability for the UE to adjust its operation while keeping the signaling overhead and device complexity minimal
