Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If frequency hopping is performed for PUSCH transmission in multiple slots, then communication flexibility and system performance are improved, but device complexity and configuration management become more complex
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting frequency hopping configurations through RRC parameters. The base station configures different hopping patterns, bandwidth parts, and frequency offsets based on channel conditions and traffic requirements, allowing the system to adapt flexibility while managing complexity through standardized parameter control
Solution Approach 2:
The patent implements dynamics by enabling flexible activation and deactivation of frequency hopping across different slots and bandwidth parts. The system can dynamically switch between hopping and non-hopping modes, adjust hopping frequencies, and adapt to changing channel conditions, thereby achieving communication flexibility without permanent complexity
2Productivity
If multiple bandwidth parts are configured for frequency hopping, then transmission efficiency is improved, but managing multiple cells and component carriers becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the uplink spectrum into multiple bandwidth parts within each cell. Each bandwidth part can be independently configured for frequency hopping, allowing efficient resource utilization across different frequency ranges while managing complexity through modular configuration of individual bandwidth parts rather than treating the entire spectrum as a single unit
Solution Approach 2:
The patent implements universality by creating a unified frequency hopping mechanism that works across multiple cells and component carriers using the same RRC parameter structure. The base station can apply identical or different hopping configurations across multiple cells, and the UE handles all cells through a consistent interface, thereby improving transmission efficiency without proportionally increasing management complexity
