Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If bandwidth parts are used in wireless communication networks, then network adaptability and resource management are improved, but devices lack information about resources corresponding to bandwidth parts
Solution Approach 1:
The patent segments the bandwidth resource into multiple bandwidth parts (BWPs), each with dedicated reference signal resource sets. This segmentation allows the network to provide targeted resource information for each BWP, resolving the information loss problem while maintaining network adaptability through selective BWP activation and management.
Solution Approach 2:
The patent implements preliminary configuration of reference signal resource sets for each bandwidth part before actual data transmission. The network pre-configures spatial quasi-co-location information and reference signal resources, ensuring that devices have the necessary resource information ready before needing to communicate on specific BWPs, thus preventing information loss.
2Measurement precision
If reference signal resource sets are configured for multiple bandwidth parts, then radio link quality assessment accuracy is improved, but device complexity increases
Solution Approach 1:
The patent creates a universal framework where reference signal resource sets serve multiple purposes: they are used for both radio link quality assessment and for establishing spatial quasi-co-location relationships across different bandwidth parts. This multi-functionality improves measurement accuracy without proportionally increasing device complexity, as the same reference signal infrastructure supports multiple measurement and assessment functions.
Solution Approach 2:
The patent enables dynamic parameter changes by allowing reference signal resource sets to be configured with different parameters for different bandwidth parts. Devices can adjust their measurement parameters based on the active BWP and its associated reference signal configuration, improving assessment accuracy while managing complexity through parameter-based flexibility rather than structural complexity.
