Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple transmission parameter sets are configured for simultaneous uplink transmissions to multiple CORESET pools, then the system's capability to handle multiple transmission elements and targets is improved, but the device complexity and configuration overhead increase
Solution Approach 1:
The patent divides the transmission configuration into multiple independent parameter sets, each associated with a specific CORESET pool index. This segmentation allows the system to handle multiple transmission targets simultaneously while maintaining clear separation of configuration parameters, reducing the complexity of managing multi-target transmissions through structured organization of transmission parameter sets
Solution Approach 2:
The patent creates a universal configuration framework where a single uplink transmission can be associated with multiple CORESET pools through multiple transmission parameter sets. This multi-functional approach enables the same uplink transmission mechanism to serve multiple transmission targets and purposes simultaneously, enhancing system versatility without requiring separate dedicated mechanisms for each target
2Productivity
If multiple transmission parameter sets are used for simultaneous uplink transmissions, then data transmission efficiency is improved, but the processing overhead and computational complexity increase
Solution Approach 1:
The patent performs preliminary configuration of multiple transmission parameter sets before actual uplink transmissions occur. By pre-configuring the parameter sets and associating them with CORESET pool indices, the system prepares all necessary transmission parameters in advance, reducing real-time processing overhead during simultaneous uplink transmissions while maintaining high data transmission efficiency
3Loss of time
If simultaneous uplink transmissions to multiple CORESET pools are supported, then the system meets low latency requirements, but the resource management complexity increases
Solution Approach 1:
The patent applies local quality by associating specific transmission parameter sets with specific CORESET pool indices, allowing different transmission characteristics and parameters to be optimized for different transmission targets. This localized configuration approach enables simultaneous uplink transmissions to multiple pools with appropriate local optimizations while maintaining manageable resource management through clear index-based associations
