Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple CORESET pools are configured to support explosive data traffic and increased number of connected devices, then system capacity and data transmission capability are improved, but device complexity and difficulty of managing control resources increase
Solution Approach 1:
The control resource set (CORESET) is divided into multiple pools, where each pool is independently managed and associated with specific transmission and reception points (TRPs). This segmentation allows the system to handle multiple connected devices and explosive data traffic by distributing control resources across different pools, thereby improving system capacity while maintaining manageable complexity through structured organization.
Solution Approach 2:
A determination mechanism is introduced as an intermediary to select which CORESET pool should be used for receiving physical downlink control channels (PDCCH). This mediator resolves the complexity of managing multiple CORESET pools by providing a systematic method for pool selection based on specific criteria, thereby simplifying control resource management while supporting enhanced data transmission capability.
2Productivity
If multiple CORESET pools are configured to accommodate significantly increased number of connected devices, then system capacity is improved, but difficulty of detecting and measuring control resources increases
Solution Approach 1:
Each CORESET pool is assigned distinct local characteristics and properties, such as being associated with specific TRPs or having unique identification features. This allows connected devices to easily detect and measure control resources by identifying the specific pool characteristics, thereby accommodating significantly increased numbers of connected devices without increasing the difficulty of control resource identification.
3Speed
If multiple CORESET pools are configured to support explosive data traffic, then data transmission rate is improved, but device complexity increases
Solution Approach 1:
The system dynamically selects which CORESET pool to use based on current traffic conditions, device requirements, and TRP availability. This dynamic approach enables the system to support explosive data traffic by flexibly allocating control resources from appropriate pools, thereby achieving high data transmission rates while managing device complexity through adaptive resource selection rather than static complex management.
