Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple bandwidth part configurations are maintained for different downlink and uplink bandwidth parts, then adaptability and versatility of the communication system are improved, but device complexity and configuration management difficulty increase
Solution Approach 1:
The patent divides the overall bandwidth configuration into multiple independent bandwidth part configurations, each with its own parameters and characteristics. This segmentation allows the system to manage complex bandwidth requirements by breaking them down into smaller, more manageable units that can be independently configured and activated based on specific communication needs.
Solution Approach 2:
The patent implements dynamic bandwidth part configuration where the system can switch between different bandwidth part configurations based on current communication conditions, traffic requirements, and resource availability. This dynamic approach allows the configuration to adapt in real-time without requiring complete reconfiguration, thereby managing complexity while maintaining versatility.
2Productivity
If bandwidth part switching is implemented for optimal resource allocation, then productivity and resource utilization are improved, but loss of time due to switching operations increases
Solution Approach 1:
The patent pre-configures multiple bandwidth part configurations with all necessary parameters and characteristics defined in advance. This preliminary configuration allows the system to switch between bandwidth parts by simply activating pre-defined configurations rather than performing complex setup operations during switching, thereby reducing switching time while maintaining optimal resource allocation capabilities.
3Reliability
If seamless signal reception and transmission are achieved through bandwidth part management, then reliability of communication is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple bandwidth part configurations into a unified management framework where configurations can be coordinated and switched seamlessly. This merging approach ensures that signal reception and transmission maintain reliability by coordinating transitions between bandwidth parts while managing complexity through unified control mechanisms rather than independent management of each bandwidth part.
