Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no clear method is provided for terminals to set data transmission type, then the system maintains simplicity, but transmission reliability deteriorates due to inconsistent understanding between terminal and network side
Solution Approach 1:
The patent applies parameter changes by establishing specific threshold values for path loss and uplink data size to determine the data transmission type. The terminal compares measured path loss against a first threshold and uplink data size against a second threshold to select between small data transmission and random access transmission, thereby resolving the inconsistency in transmission type selection while maintaining systematic simplicity.
Solution Approach 2:
The patent enables the terminal to autonomously determine the data transmission type by itself based on local measurements of path loss and uplink data size, without requiring complex network-side coordination or additional signaling. This self-service approach improves transmission reliability by ensuring consistent decision-making at the terminal while avoiding the complexity of centralized control mechanisms.
2Measurement precision
If multiple transmission types are supported without clear selection criteria, then transmission adaptability improves, but transmission accuracy deteriorates due to inconsistent understanding between terminal and network
Solution Approach 1:
The patent uses parameter changes by defining specific threshold values for path loss and uplink data size that govern the selection between different transmission types. By comparing measured parameters against these thresholds, the system achieves precise and consistent transmission type selection that is reproducible at both terminal and network side, thereby improving measurement precision while maintaining adaptability.
Solution Approach 2:
The patent implements feedback mechanisms where the terminal determines the transmission type based on measured path loss and data size, and the network side can provide configuration information and thresholds to the terminal. This feedback loop ensures that both terminal and network side have consistent understanding of the transmission type selection criteria, improving selection accuracy while preserving the ability to adapt to different channel conditions and data requirements.
3Productivity
If transmission type selection is left undefined, then implementation flexibility is maintained, but resource allocation efficiency deteriorates due to inconsistent understanding between terminal and network
Solution Approach 1:
The patent improves resource allocation efficiency by introducing clear parameter-based selection criteria involving path loss thresholds and uplink data size thresholds. These parameter changes enable consistent determination of transmission type at both terminal and network side, ensuring that resources are allocated appropriately based on actual channel conditions and data requirements, thereby improving productivity without adding significant implementation complexity.
