Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If more communication nodes are added to address interference issues, then interference mitigation capability is improved, but device complexity and network congestion increase
Solution Approach 1:
The patent implements a feedback mechanism where communication nodes continuously monitor interference levels in their environment and dynamically adjust their transmission parameters. The node receives interference information, determines whether to switch resource blocks based on interference thresholds, and adjusts its communication strategy accordingly. This closed-loop feedback system enables individual nodes to autonomously mitigate interference without requiring additional network infrastructure.
Solution Approach 2:
The communication node performs self-service by autonomously detecting interference, evaluating its communication quality, and switching resource blocks without external intervention. The node independently monitors its communication links, determines interference conditions, and executes resource block switching decisions based on predetermined thresholds, eliminating the need for manual configuration or additional network management nodes.
2Reliability
If traffic is redirected to avoid interference, then communication reliability is improved, but loss of time and reduced productivity occur
Solution Approach 1:
The patent implements preliminary action by pre-configuring multiple resource blocks and establishing interference threshold criteria before interference occurs. The communication node maintains a set of alternative resource blocks ready for use, and pre-determines the switching criteria based on interference levels. When interference is detected, the node can immediately switch to a pre-identified alternative resource block without requiring real-time analysis or decision delays.
Solution Approach 2:
The resource block switching mechanism is dynamic, allowing the communication node to adapt its transmission parameters in real-time based on interference conditions. The node continuously monitors interference levels and dynamically adjusts its resource block selection, switching frequency, and transmission power to optimize communication reliability while minimizing disruption to ongoing data traffic.
3Measurement precision
If adaptive filtering techniques are applied to suppress interferers, then signal quality is improved, but device complexity and energy consumption increase
Solution Approach 1:
The patent applies local quality by implementing filtering and interference mitigation only in the specific frequency bands or resource blocks where interference is detected. Instead of applying comprehensive filtering across the entire spectrum, the node selectively processes only the affected resource blocks, reducing the overall computational load and energy consumption while maintaining signal quality in the interfered channels.
Solution Approach 2:
The communication node applies partial action by implementing interference mitigation techniques only when and where interference thresholds are exceeded. The node monitors interference levels and activates filtering or resource block switching only in the specific resource blocks affected by interference, rather than applying continuous comprehensive filtering across all communications, thereby reducing unnecessary energy consumption.
