Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple uplink channel configurations are determined for different frequency domain resource sets, then resource utilization rate is improved, but device complexity increases
Solution Approach 1:
The frequency domain resources are segmented into multiple frequency domain resource sets, with each set associated with a specific uplink channel configuration. This segmentation allows the system to optimize resource utilization by matching specific configurations to specific resource sets, thereby improving overall resource utilization rate while managing complexity through structured organization.
Solution Approach 2:
The patent implements dynamic switching between different uplink channel configurations based on the activated frequency domain resource set. The network can dynamically adjust which configuration is active, allowing the system to adapt to changing conditions and optimize performance without requiring all configurations to be simultaneously active, thus managing device complexity.
2Adaptability or versatility
If multiple uplink channel configurations are determined for different frequency domain resource sets, then adaptability is improved, but device complexity increases
Solution Approach 1:
Multiple uplink channel configurations are determined, where each configuration can serve different frequency domain resource sets. This multi-functionality approach allows the same configuration structure to be universally applied across different resource sets, improving adaptability while avoiding the need for completely separate configuration mechanisms for each scenario.
Solution Approach 2:
The patent changes parameters such as time domain resource allocation, frequency domain resource allocation, and physical uplink shared channel configuration based on the activated frequency domain resource set. By adjusting these parameters dynamically, the system achieves high adaptability to different scenarios without requiring fundamentally different system architectures, thus managing device complexity.
3Productivity
If dynamic scheduling of physical uplink shared channel is used, then productivity is improved, but signaling overheads increase
Solution Approach 1:
Uplink channel configurations are determined and prepared in advance for different frequency domain resource sets. This preliminary action allows the network to have configurations ready before actual transmission occurs, enabling fast dynamic scheduling without requiring extensive real-time signaling, thus reducing signaling overheads while maintaining high productivity.
Solution Approach 2:
The patent uses reference signal concepts where configurations can be copied or referenced from existing templates. By having pre-determined configurations that can be referenced and activated based on the frequency domain resource set, the system reduces the need for repeated detailed signaling, thereby reducing signaling overheads while maintaining dynamic scheduling capabilities for high productivity.
