Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed processing time is allocated for terminal tasks, then system simplicity is maintained, but processing flexibility and adaptability to varying task complexities deteriorate
Solution Approach 1:
The patent applies dynamics by making the processing time parameter configurable and adaptable. Instead of fixed processing time, the system allows dynamic adjustment of the starting symbol position of uplink data channels based on terminal processing capabilities and task requirements. The base station can flexibly configure the time parameter K2 (offset between downlink data and uplink acknowledgment) and starting symbol positions to match varying processing complexities, thus resolving the contradiction between adaptability and system simplicity.
Solution Approach 2:
The patent implements parameter changes by introducing configurable parameters for processing time. The base station determines and signals to the terminal specific parameter values such as the starting symbol position of uplink data channel, which directly controls processing time duration. This allows the system to adapt processing time to different task complexities (CSI feedback, BSI feedback, UL data preparation) without fundamentally changing system architecture, thereby improving adaptability while managing complexity through parameterization.
2Reliability
If processing time is extended to handle high complexity tasks, then processing reliability improves, but time efficiency and productivity deteriorate
Solution Approach 1:
The patent applies local quality by providing differentiated processing time allocations for different terminal tasks and different terminals. Instead of uniform processing time for all tasks, the system configures specific starting symbol positions and time offsets for different task types (UL data, CSI feedback, BSI feedback) and adjusts according to terminal capabilities. This ensures each task receives appropriate processing time locally optimized for its requirements, improving reliability without unnecessary time extension across all operations.
Solution Approach 2:
The patent implements partial action by allocating processing time precisely according to task requirements rather than providing excessive uniform time for all tasks. The base station determines minimum necessary processing time for each specific task type and terminal capability combination, configuring starting symbol positions to provide just sufficient time for reliable processing. This avoids the productivity loss from universally extended processing time while ensuring reliability where needed through task-specific time allocation.
