Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If network energy saving measures are implemented in anchor cells, then energy consumption is reduced, but connection reliability may deteriorate
Solution Approach 1:
The patent divides the cell into anchor cell and non-anchor cell functionalities. The anchor cell maintains full functionality for connection reliability, while non-anchor cells can be deactivated or operated in reduced functionality mode for energy saving. This segmentation allows different parts of the network to serve different purposes simultaneously.
Solution Approach 2:
The patent implements dynamic bandwidth part (BWP) adaptation and switching, allowing the network to adjust transmit and receive bandwidths dynamically based on traffic conditions. During low activity periods, bandwidth is reduced to save energy; during high activity, full bandwidth is restored to maintain reliability.
2Use of energy by moving object
If bandwidth is reduced for energy saving, then energy consumption decreases, but service quality may deteriorate
Solution Approach 1:
The patent employs dynamic BWP switching that adjusts bandwidth based on real-time traffic conditions and service requirements. Critical services maintain high quality even during energy-saving modes, while non-critical services operate with reduced bandwidth. The system dynamically switches between different BWP configurations to balance energy consumption and service quality.
Solution Approach 2:
Different quality levels are provided for different services and user groups. High-priority services maintain full service quality regardless of energy-saving mode, while lower-priority services accept reduced quality. This local differentiation of quality allows the system to save energy overall while protecting critical service levels.
3Stability of the object's composition
If anchor cells operate continuously for reliability, then connection stability is maintained, but energy waste increases
Solution Approach 1:
The patent segments cell functionality into anchor and non-anchor roles. The anchor cell maintains continuous operation for connection stability, while non-anchor cells can be deactivated or put into reduced functionality mode when not needed, eliminating energy waste from continuously operating redundant cells.
Solution Approach 2:
The system implements periodic evaluation of cell activity and traffic conditions to determine when non-anchor cells should be activated or deactivated. This periodic assessment allows the network to maintain stability through anchor cells while avoiding continuous operation of all cells, thereby reducing energy waste.
