Engineering Contradiction Analysis
1Object-affected harmful factors
If orthogonal channels are assigned to all entities with overlapping coverage contours, then interference is reduced, but spectrum utilization efficiency deteriorates due to excessive channel assignments
Solution Approach 1:
The patent applies local quality by differentiating channel assignment strategies based on the degree and type of overlap between coverage contours. Instead of uniformly assigning orthogonal channels to all overlapping entities, the system evaluates the specific overlap characteristics and applies appropriate channel assignment only where necessary, thereby reducing unnecessary spectrum consumption while maintaining interference protection where needed.
Solution Approach 2:
The patent changes the parameter of channel assignment by introducing a nuanced classification system that adjusts channel allocation based on overlap severity. The system transitions from a binary orthogonal/non-orthogonal assignment to a multi-level approach where channel assignment parameters are modified according to the specific overlap scenario, optimizing both interference reduction and spectrum utilization.
2Measurement precision
If coverage contour thresholds are reduced to detect more overlaps, then interference detection improves, but false interference detection increases leading to unnecessary orthogonal channel assignments
Solution Approach 1:
The patent applies preliminary action by pre-establishing classification criteria and decision rules for evaluating coverage contour overlaps. Before performing actual channel assignments, the system prepares a framework that defines how different overlap scenarios should be interpreted and handled, thereby reducing false detections and simplifying the subsequent channel assignment process.
Solution Approach 2:
The patent implements feedback mechanisms where the results of overlap evaluations are used to refine and adjust the classification criteria. The system continuously learns from detected overlap patterns and adjusts its detection thresholds and classification rules to minimize false positives while maintaining accurate interference detection, thereby reducing unnecessary orthogonal channel assignments.
3Reliability
If interference thresholds are lowered to protect against more interference, then communication reliability improves, but spectrum resource utilization deteriorates
Solution Approach 1:
The patent applies local quality by implementing location-specific and scenario-specific interference protection strategies. Instead of applying a uniform low interference threshold across all entities and scenarios, the system adjusts protection levels based on the specific geographic location, service type, and overlap characteristics, thereby maintaining high reliability where needed while allowing more aggressive spectrum utilization in appropriate contexts.
