5G Uplink HARQ-ACK Prioritization for Flexible Feedback Timing

The patent implements dynamic HARQ-ACK feedback delay where the terminal determines the feedback timing based on priority levels of control signaling. Different priority levels (first priority and second priority) correspond to different feedback delays, allowing the system to adapt flexibly to diverse user demands while maintaining manageable complexity through structured priority-based rules

The patent changes the parameter of feedback delay based on priority level. When control signaling is identified as high priority, a first (shorter) feedback delay is applied; when low priority, a second (longer) feedback delay is applied. This parameter change approach enables adaptability while keeping the system complexity controlled through clear parameter differentiation

The patent segments control signaling into different priority levels (first priority and second priority), allowing differentiated handling of high-priority and low-priority signals. This segmentation enables the system to meet diverse user demands by providing priority-based resource allocation while managing complexity through clear categorization rules

The patent applies different resource allocation strategies to different priority levels. High-priority control signaling receives preferential treatment in terms of feedback timing and resource allocation, while low-priority signaling follows standard procedures. This local quality approach enables adaptability for specific priority levels without increasing overall system complexity
