Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional carrier aggregation assigns multiple frequency bands to user devices, then user devices can access more spectrum, but spectrum waste occurs and spectrum efficiency deteriorates
Solution Approach 1:
The patent changes the parameter of bandwidth allocation from fixed standard widths (e.g., 100 MHz, 200 MHz) to flexible odd bandwidths (e.g., 101 MHz, 203 MHz) that precisely match the available spectrum resources. This allows the carrier aggregation system to allocate spectrum in exact increments corresponding to resource block groups, eliminating the spectrum waste that occurs when standard bandwidth allocations leave unused frequency portions.
2Ease of manufacture
If fixed bandwidth allocation is used in carrier aggregation, then implementation is simpler, but spectrum waste increases and data speed is limited
Solution Approach 1:
The patent introduces dynamic bandwidth allocation where the carrier aggregation system can flexibly adjust the bandwidth of aggregated carriers based on available spectrum resources and device capabilities. Instead of being constrained to fixed bandwidth values, the system dynamically determines optimal bandwidths (including odd values) to maximize spectrum utilization and data throughput while maintaining manageable implementation complexity through standardized procedures.
3Adaptability or versatility
If standard carrier aggregation bandwidth limits are applied, then device compatibility is maintained, but operators cannot fully utilize available spectrum leading to wasted resources
Solution Approach 1:
The patent applies local quality by allowing different bandwidth configurations for different carriers within the same carrier aggregation setup. While maintaining overall device compatibility through standardized carrier aggregation mechanisms, the system enables specific carriers to have customized bandwidths (including odd bandwidths) that precisely match local spectrum availability. This localized flexibility allows operators to fully utilize available spectrum resources without requiring changes to device hardware or fundamental compatibility.
