Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If time domain information in control information is designed in a unified manner to take various data transmission scenarios into account, then the system can support flexible time domain resource scheduling, but the signaling overheads of the control information become relatively high
Solution Approach 1:
The patent segments time domain information design by detection period, dividing control channels into different groups (first group with first detection period, second group with second detection period) that use different time domain information designs. This allows each segment to be optimized independently, reducing overall signaling overhead while maintaining flexibility for different data transmission scenarios
Solution Approach 2:
The patent applies local quality by configuring different time domain information parameters for different control channel groups based on their specific detection periods. Control channels with shorter detection periods use one set of time domain information configurations, while those with longer detection periods use another set, allowing each local configuration to be optimized for its specific requirements rather than using a one-size-fits-all approach
2Ease of operation
If different detection periods of control channel are configured to satisfy different transmission requirements, then detection flexibility is improved and energy loss is reduced, but the system complexity increases
Solution Approach 1:
The patent implements dynamics by allowing the system to adaptively select different detection periods and corresponding time domain information configurations based on transmission requirements. The base station can dynamically configure control channels into different groups with appropriate detection periods, and the terminal can dynamically adjust its detection behavior according to the configured group, optimizing both flexibility and energy efficiency while managing complexity through structured configuration
