Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the distribution method is used where mobile terminals independently determine communication parameters by scanning frequencies, then device complexity and energy consumption are reduced at the terminal, but communication efficiency deteriorates due to lack of global viewpoint leading to hidden node problems and simultaneous transmissions on the same channel
Solution Approach 1:
An RF resource allocation device acts as an intermediary between mobile terminals and the radio frequency spectrum. This central device collects channel state information from multiple terminals, determines optimal frequency allocations considering global conditions, and notifies terminals of their assigned resources. This mediator resolves the conflict by enabling centralized optimization while keeping terminal operations simple.
Solution Approach 2:
Instead of having terminals independently scan and determine frequencies (bottom-up approach), the system inverts the control direction by having a central RF resource allocation device determine and notify terminals of frequency assignments (top-down approach). This inversion enables global optimization of communication efficiency while maintaining terminal simplicity.
2Adaptability or versatility
If multiple mobile terminals perform independent frequency scanning simultaneously, then terminal autonomy is maintained, but message loss increases due to simultaneous transmissions on the same channel
Solution Approach 1:
The system implements feedback loops where mobile terminals report channel state information to the RF resource allocation device, which then adjusts frequency allocations based on this feedback. This feedback mechanism maintains terminal autonomy in reporting while enabling centralized coordination to prevent simultaneous transmissions and message loss.
Solution Approach 2:
The RF resource allocation device serves as a mediator that receives autonomous terminal reports, processes global channel conditions, and coordinates frequency assignments to prevent conflicts. This mediator enables terminals to maintain autonomy in data collection while ensuring reliable communication through centralized coordination.
3Device complexity
If static white space information from WSDB is used for communication parameter control, then system complexity is reduced, but adaptability to real-time communication conditions deteriorates
Solution Approach 1:
The system transitions from static WSDB information to dynamic real-time channel state monitoring. Mobile terminals continuously measure channel conditions and report to the RF resource allocation device, which dynamically adjusts frequency allocations based on current conditions. This dynamic approach maintains manageable complexity while significantly improving real-time adaptability.
Solution Approach 2:
Instead of relying on static, periodic WSDB updates, the system implements continuous channel state monitoring and reporting. Terminals continuously measure channel conditions and the RF resource allocation device continuously optimizes frequency assignments, ensuring uninterrupted adaptation to changing communication conditions while maintaining system simplicity.
4Productivity
If channel utilization rate increases to improve communication efficiency, then throughput improves, but the severity of hidden node problems and simultaneous transmission conflicts increases
Solution Approach 1:
The RF resource allocation device acts as a mediator that coordinates frequency usage across multiple terminals. By collecting channel state information from all terminals and centrally determining frequency allocations, this mediator enables high channel utilization while preventing hidden node problems and simultaneous transmission conflicts through coordinated resource assignment.
Solution Approach 2:
The system assigns different frequencies to different terminals based on their local channel conditions and spatial relationships. This local quality approach allows each terminal to operate at high utilization on its assigned frequency while the central coordinator ensures that spatially separated terminals using the same frequency do not cause hidden node problems or conflicts.
