Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a shared channel transmission is performed based on a same configuration in flexible duplex manner, then device complexity is reduced, but transmission performance is affected due to different interference patterns and bandwidth characteristics
Solution Approach 1:
The patent segments the configuration parameters into two distinct groups: first parameters for downlink interference scenarios and second parameters for uplink interference scenarios. This segmentation allows the system to apply appropriate configurations based on the specific interference pattern, resolving the contradiction between configuration simplicity and transmission performance by introducing targeted complexity only where needed.
Solution Approach 2:
The patent implements dynamic parameter selection based on interference detection. The network device determines whether downlink or uplink interference is present and dynamically applies the corresponding parameter set. This dynamic approach maintains configuration flexibility while ensuring optimal transmission performance for each interference scenario.
2Reliability
If separate configuration is applied for different time domain units, then transmission performance is optimized, but device complexity increases due to multiple parameter sets
Solution Approach 1:
The patent applies local quality by configuring different parameters for specific local conditions (interference types). Instead of uniformly complex configuration across all scenarios, the system applies enhanced configuration only where interference is detected, maintaining simplicity in interference-free scenarios while optimizing performance where needed.
Solution Approach 2:
The patent changes parameters based on detected interference conditions. The network device monitors interference patterns and switches between first parameters (for downlink interference) and second parameters (for uplink interference). This parameter change strategy optimizes transmission performance by adapting to local conditions without requiring permanently complex configuration management.
