Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If time-frequency resources are allocated for signals from both licensed and unlicensed bands, then resource utilization improves, but interference between bands increases
Solution Approach 1:
The patent segments time-frequency resources by creating separate resource pools for licensed band signals (first node) and unlicensed band signals (second node). The terminal device is configured with distinct time-frequency resource allocations for each band, preventing overlap and interference while maintaining efficient utilization of both bands for their respective services.
2Adaptability or versatility
If the terminal monitors signals from both first node and second node simultaneously, then service coverage improves, but reception performance deteriorates due to interference
Solution Approach 1:
The patent divides the reception resources into separate segments for the first node (licensed band) and second node (unlicensed band). The terminal is configured with node-specific time-frequency resources, allowing simultaneous monitoring of both nodes while preventing interference between them, thus maintaining reliable reception performance across both bands.
Solution Approach 2:
The patent applies local quality by optimizing resource allocation specifically for each node's characteristics. The first node receives dedicated time-frequency resources appropriate for licensed band operations, while the second node receives separate resources suited for unlicensed band conditions, allowing each to operate at optimal performance without mutual degradation.
3Measurement precision
If the terminal uses time-frequency resources for channel state information and reference signals, then channel estimation accuracy improves, but resource availability for data transmission decreases
Solution Approach 1:
The patent segments resource allocation by dedicating specific time-frequency resources for channel state information and reference signals for each node separately. This segmented approach ensures accurate channel estimation for both licensed and unlicensed bands while efficiently utilizing remaining resources for data transmission, avoiding waste and optimizing overall resource usage.
