Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the time interval for half-duplex operation is fixed, then the system configuration is simple, but the system cannot adapt to dynamic interference conditions and optimize communication efficiency
Solution Approach 1:
The patent applies dynamics by enabling the second time interval to be dynamically changed from full-duplex to half-duplex operation based on downlink control information. This allows the system to adapt to varying interference conditions while maintaining a relatively simple pre-configured structure, resolving the contradiction between adaptability and configuration complexity.
Solution Approach 2:
The patent changes the operational parameter (duplex mode) of the second time interval from fixed to variable. By allowing the duplex mode parameter to change based on control information, the system achieves adaptability to interference conditions without requiring complete reconfiguration of the time interval structure.
2Productivity
If downlink control information is used to dynamically change the second time interval, then communication efficiency is optimized, but control information overhead increases
Solution Approach 1:
The patent segments the time resource period into multiple time intervals with different functions. The first time interval is fixed for full-duplex operation, while the second time interval is dynamically configurable. This segmentation allows efficient use of control information by only signaling changes for the variable portion, reducing overall overhead while maintaining communication efficiency.
Solution Approach 2:
Instead of dynamically controlling the entire time resource period, the patent applies partial action by only dynamically changing the second time interval while keeping the first time interval fixed. This reduces the amount of control information needed while still achieving optimization of communication efficiency in the variable portion.
3Productivity
If the first time interval is designated for full-duplex operation, then spectrum utilization is improved, but interference management becomes more difficult
Solution Approach 1:
The patent segments the time resource period into distinct time intervals, with the first time interval dedicated to full-duplex operation and the second time interval configurable for half-duplex operation. This segmentation allows the system to maintain high spectrum utilization during full-duplex intervals while managing interference through controlled half-duplex intervals, resolving the contradiction between productivity and harmful factors.
