Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a common NR frame structure with fixed feedback timing is used, then system simplicity and standardization are improved, but adaptability to diverse applications with variable requirements deteriorates
Solution Approach 1:
The patent applies dynamics by transitioning from fixed feedback timing to dynamic feedback timing determination. The network side device determines feedback timing based on real-time information about the terminal device's capability, service type, and timing requirements, allowing the system to adapt to different applications while maintaining a unified frame structure.
Solution Approach 2:
The patent changes the feedback timing parameter dynamically based on terminal device characteristics. Instead of using a fixed timing value, the system adjusts the feedback timing parameter according to the terminal's processing capability, service type requirements, and network conditions, thereby achieving adaptability without increasing structural complexity.
2Productivity
If fixed feedback timing is used, then implementation simplicity is improved, but communication efficiency for devices with different processing capabilities deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the terminal device provides information about its processing capability and timing requirements to the network side device. The network then uses this feedback information to determine appropriate feedback timing, creating a closed-loop system that optimizes communication efficiency while maintaining implementation simplicity.
Solution Approach 2:
The patent applies preliminary action by having the terminal device report its capability and timing requirements in advance before actual communication occurs. This allows the network side device to pre-determine the appropriate feedback timing, ensuring efficient communication without requiring complex real-time adjustments during data transmission.
3Reliability
If uniform feedback timing is applied to all devices, then system configuration simplicity is improved, but meeting delay requirements for devices with different processing times deteriorates
Solution Approach 1:
The patent applies local quality by tailoring feedback timing to individual terminal devices based on their specific processing capabilities and service type requirements. Each device receives customized timing configuration that matches its local characteristics, ensuring reliable delay requirement fulfillment without requiring complex system-wide timing management.
