Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple transmission schemes are supported in the system, then adaptability to various environments is improved, but device complexity increases
Solution Approach 1:
The system dynamically selects transmission schemes based on receiver capability information and channel conditions. The base station adapts the transmission scheme in real-time by receiving capability information from the terminal and selecting an appropriate scheme from multiple supported schemes, making the system flexible without requiring all components to be permanently complex.
Solution Approach 2:
The patent changes the parameter of transmission scheme selection based on receiver capability information. By varying the transmission scheme parameters according to the terminal's capabilities and channel conditions, the system achieves adaptability while maintaining manageable complexity through parameterized configuration rather than hard-coded complexity.
2Device complexity
If transmission schemes are limited due to system design constraints, then device complexity is reduced, but adaptability to various environments deteriorates
Solution Approach 1:
The system performs preliminary action by having the terminal report its capability information in advance. The base station uses this pre-acquired information to select an appropriate transmission scheme before actual data transmission, avoiding the need for complex real-time adaptation while maintaining good adaptability through informed selection.
Solution Approach 2:
Capability information acts as an intermediary that bridges the gap between limited system design and environmental adaptability. This intermediate information layer allows the system to select appropriate transmission schemes without directly implementing all possible schemes, reducing complexity while maintaining adaptability through information-mediated selection.
3Device complexity
If the system fails to adaptively change transmission schemes according to various environments, then device complexity is reduced, but transmission performance deteriorates
Solution Approach 1:
The system implements feedback through the terminal reporting capability information to the base station. This feedback mechanism enables the base station to adaptively select transmission schemes that match the terminal's capabilities and channel conditions, improving transmission performance without requiring the system to maintain all possible schemes simultaneously, thus managing complexity.
