Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sub-band full duplex communication is used to enhance network capacity and resource utilization, then spectrum efficiency is improved, but interference (e.g., self-interference) increases
Solution Approach 1:
The patent applies dynamics by enabling the network node to switch between sub-band full duplex mode and half duplex mode based on real-time traffic conditions and interference levels. The system dynamically adjusts the communication mode to optimize the balance between capacity and interference, rather than being fixed in one mode.
Solution Approach 2:
The patent changes the operational parameters of the network node by transitioning between different communication modes (full duplex and half duplex). This parameter change allows the system to adapt to varying network conditions, adjusting the duplex mode based on traffic demand and interference characteristics.
2Productivity
If sub-band full duplex communication is used to improve resource utilization, then spectrum efficiency is enhanced, but adaptability to dynamic traffic conditions decreases
Solution Approach 1:
The system implements dynamics by continuously monitoring traffic conditions and adjusting the communication mode accordingly. The network node can transition between full duplex and half duplex modes based on real-time demands, ensuring optimal resource utilization while maintaining adaptability to changing network conditions.
Solution Approach 2:
The patent incorporates feedback mechanisms where the network node monitors traffic conditions and interference levels, then adjusts its operation accordingly. This feedback loop ensures that the system adapts to dynamic traffic conditions while maintaining high resource utilization efficiency.
3Device complexity
If fixed time periods are configured for half duplex communication, then implementation simplicity is maintained, but network performance is suboptimal under dynamic conditions
Solution Approach 1:
The patent transforms the static configuration into a dynamic system where the communication mode can change based on real-time conditions. This allows the network to maintain simplicity in basic configuration while achieving optimal performance through dynamic adaptation to traffic conditions.
