Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If carrier aggregation and bandwidth part configuration are implemented for flexible resource allocation, then adaptability and resource utilization improve, but device complexity and processing requirements increase
Solution Approach 1:
The patent divides the wide bandwidth into multiple bandwidth parts (BWPs), each representing a segment of the total bandwidth. This segmentation allows the system to flexibly allocate and manage different portions of bandwidth independently, enabling adaptive resource allocation while maintaining manageable complexity through modular BWP structures that can be activated or deactivated as needed
Solution Approach 2:
The patent implements dynamic BWP switching mechanisms that allow the system to adaptively change active bandwidth parts based on current traffic conditions, channel quality, and service requirements. This dynamic adjustment enables the system to optimize resource utilization in real-time while maintaining operational simplicity through automated switching logic
2Productivity
If advanced bandwidth management techniques are implemented across multiple cells and carriers, then network efficiency improves, but processing time and computational requirements increase
Solution Approach 1:
The patent pre-configures multiple bandwidth parts and establishes switching criteria in advance, allowing the system to rapidly respond to changing conditions without extensive real-time computation. By preparing BWP configurations and switching rules beforehand, the system minimizes processing delays while maintaining high network efficiency through ready-to-execute switching decisions
Solution Approach 2:
The patent implements feedback mechanisms that monitor channel conditions, traffic load, and BWP performance metrics, using this information to automatically adjust bandwidth allocations and trigger BWP switching. This closed-loop feedback system optimizes network efficiency through data-driven decisions while reducing processing time by relying on pre-established switching thresholds and automated response protocols
