Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple candidate resource sets are configured for uplink transmission, then the reliability of resource allocation is improved, but the device complexity and signaling overhead increase
Solution Approach 1:
The resource sets are segmented into multiple candidate sets (first resource set, second resource set, etc.), each containing multiple uplink resources. This segmentation allows the system to provide diverse resource options for transmission, improving reliability by enabling selection from multiple independent resource pools while managing complexity through structured organization of resource groups.
Solution Approach 2:
Multiple candidate resource sets are pre-configured and prepared in advance before actual transmission needs arise. The network device pre-establishes these resource sets with different configurations, so when transmission is needed, the UE can quickly select from the pre-prepared options without complex real-time resource negotiation, thus improving reliability while controlling complexity.
2Adaptability or versatility
If multiple candidate resource sets are configured for uplink transmission, then the adaptability of resource allocation is improved, but the signaling overhead increases
Solution Approach 1:
Multiple candidate resource sets with different configurations (time resources, frequency resources, resource blocks) are pre-configured and signaled to the UE in advance. This preliminary action provides adaptability for various transmission scenarios without requiring extensive real-time signaling, as the UE can select from pre-defined resource sets based on channel conditions and transmission requirements.
Solution Approach 2:
The system enables dynamic selection among multiple pre-configured resource sets based on varying channel conditions, traffic patterns, and transmission requirements. The UE can adaptively choose the most suitable resource set from the candidate sets, providing flexibility and adaptability while the actual signaling overhead is reduced compared to dynamic resource allocation for each transmission instance.
