Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional LTE control signaling is used, then system compatibility is maintained, but configuration flexibility is insufficient for 5G requirements
Solution Approach 1:
The patent applies dynamics by transitioning from fixed LTE control signaling to dynamic 5G control signaling that can adapt to different configuration requirements. The control information structure is designed to be flexible and configurable, allowing the system to adjust parameters dynamically based on network conditions and service requirements, thereby achieving both configuration flexibility and reliable channel estimation.
Solution Approach 2:
The patent changes key parameters of the control signaling system by introducing new control information elements that enable flexible configuration of downlink and uplink data transmission parameters. This includes modified control information structures that can accommodate various 5G-specific configurations while maintaining backward compatibility, thus resolving the contradiction between flexibility and reliability.
2Productivity
If fixed configuration parameters are used, then system simplicity is maintained, but configuration delay increases and resource usage is not optimized
Solution Approach 1:
The patent applies preliminary action by pre-configuring control information structures and parameters before actual data transmission begins. The control information is prepared and sent in advance, allowing the user equipment to configure parameters timely without causing delays during critical transmission periods. This proactive configuration approach optimizes both efficiency and timing.
Solution Approach 2:
The patent ensures continuity of useful action by maintaining continuous control information transmission and parameter configuration processes. The control signaling operates continuously to update and optimize transmission parameters in real-time, eliminating idle configuration periods and ensuring that resource allocation remains optimized throughout the communication process, thereby reducing overall configuration delay.
