Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dynamic resource allocation and carrier aggregation are implemented, then spectral efficiency and data rates are improved, but system complexity increases
Solution Approach 1:
The patent segments the bandwidth into multiple bandwidth parts (BWPs) that can be independently configured and activated. Each BWP can be associated with different numerologies and resource allocation patterns, allowing the system to divide the complex resource management task into manageable segments based on traffic conditions and user requirements.
Solution Approach 2:
The patent implements dynamic BWP switching and activation/deactivation mechanisms that adapt to changing traffic conditions in real-time. The system can dynamically adjust which BWPs are active, their configurations, and resource allocation patterns, transforming a static complex system into a dynamic adaptive one that manages complexity through flexibility.
2Speed
If multiple carriers and cells are aggregated, then data rates and coverage are improved, but management complexity increases
Solution Approach 1:
The patent merges multiple carriers and cells into a unified framework of bandwidth parts that can be managed collectively. By aggregating resources across multiple carriers and organizing them into coordinated BWPs, the system achieves higher data rates while managing complexity through unified control mechanisms rather than separate management of each carrier.
Solution Approach 2:
The patent creates a universal BWP framework that can accommodate multiple carriers, cells, and numerologies within a single management structure. This multi-functional approach allows the same BWP mechanisms to handle diverse scenarios across different carriers and cells, reducing the need for carrier-specific management complexity.
3Adaptability or versatility
If bandwidth parts are configured dynamically, then adaptability to traffic conditions is improved, but configuration complexity increases
Solution Approach 1:
The patent utilizes parameter changes in BWP configurations, such as adjusting bandwidth size, numerology, and activation status, to adapt to different traffic conditions. By changing these parameters dynamically rather than reconfiguring entire systems, the patent achieves high adaptability while managing configuration complexity through standardized parameter modifications.
