Engineering Contradiction Analysis
1Productivity
If traditional sequential processing methods are used for precoding, then processing accuracy can be maintained, but processing time and computational resource consumption increase significantly
Solution Approach 1:
The patent divides the precoding computation into multiple independent thread blocks that can execute simultaneously. Each thread block processes a portion of the precoding calculation (e.g., different antenna elements or user streams), transforming a single sequential task into parallel segments that reduce overall processing time while maintaining computational accuracy.
2Productivity
If more computing resources are allocated to precoding processing, then processing speed improves, but power consumption and resource utilization efficiency worsen
Solution Approach 1:
The patent implements dynamic resource allocation where the number of thread blocks and threads are adjusted based on real-time processing requirements, channel conditions, and available computational resources. This dynamic configuration allows the system to optimize the balance between processing speed and power consumption, allocating more resources only when necessary for high-priority transmissions or complex precoding scenarios.
