Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If channel congestion is not monitored and reported accurately, then the system operates with simpler procedures, but resource utilization efficiency deteriorates and latency increases
Solution Approach 1:
The patent replaces complex qualitative congestion assessment with quantitative measurement based on RSSI thresholds and busy sample counting. This systematic measurement approach substitutes subjective or simplistic congestion detection with objective metrics, improving resource utilization efficiency through data-driven decisions while maintaining manageable complexity through standardized measurement procedures.
Solution Approach 2:
The patent introduces specific measurable parameters (RSSI values, busy sample counts, contention ratios) to quantify channel congestion. By changing from qualitative congestion assessment to quantitative parameter measurement, the system achieves better resource utilization efficiency through precise congestion level detection, while the complexity remains controlled through defined measurement intervals and threshold-based reporting.
2Measurement precision
If detailed channel congestion measurements are performed frequently, then congestion management accuracy improves, but time consumption and processing overhead increase
Solution Approach 1:
The patent implements periodic channel measurements at defined intervals rather than continuous monitoring. This periodic approach maintains measurement precision by regularly updating congestion status while reducing time consumption and processing overhead compared to continuous measurement. The system performs RSSI measurements and busy sample counting at scheduled intervals, balancing accuracy requirements with time efficiency.
Solution Approach 2:
The patent measures congestion parameters for a sufficient duration to achieve accurate readings without excessive measurement time. By determining congestion based on busy sample counts within specific reporting intervals and using threshold-based RSSI evaluation, the system obtains precise congestion measurements while avoiding unnecessary extended measurement periods that would increase time loss and processing overhead.
3Quantity of substance
If the number of user equipments increases, then system capacity and service coverage improve, but channel congestion and resource contention worsen
Solution Approach 1:
The patent implements feedback mechanisms where wireless nodes report channel congestion status (contention ratios, busy sample counts) to the network. This feedback enables the network to monitor congestion levels across multiple user equipments and adjust resource allocation accordingly. As the number of user equipments increases, the feedback system provides real-time congestion information, allowing the network to manage resource contention effectively and mitigate the harmful effects of increased congestion.
Solution Approach 2:
The patent introduces congestion measurement and reporting as an intermediary mechanism between user equipments and network resource allocation. This intermediary system quantifies channel congestion through RSSI measurements and busy sample counting, providing the network with actionable information to manage resource distribution. The intermediary congestion reporting system enables effective management of increasing user equipment numbers by translating physical channel conditions into manageable metrics for network optimization.
