Configured Grant HARQ Process Selection for Collision Handling

The patent segments the HARQ process selection into multiple distinct scenarios based on collision conditions. When HARQ process collisions are detected among multiple CG resource occasions, the system divides the handling into different cases: selecting based on priority values when priorities differ, selecting based on timing when priorities are equal, and other specific scenarios. This segmentation allows precise control over HARQ process selection to prevent transmission failures while maintaining high transmission capacity.

The patent implements dynamic HARQ process selection rules that adapt to different collision scenarios. Rather than using a fixed simple selection method, the system dynamically determines the appropriate selection strategy based on the specific collision condition detected. The terminal device evaluates priority values, timing information, and other parameters to dynamically choose the most appropriate HARQ process, thereby maintaining reliability without requiring overly complex predetermined rules.

The patent applies preliminary action by establishing predetermined HARQ process selection rules that are configured in advance. The network device and terminal device both store and understand the collision handling rules beforehand, including priority-based selection, timing-based selection, and other scenario-specific rules. When a collision occurs, the terminal device simply applies the pre-configured rules without needing to perform complex real-time analysis, thus improving reliability while keeping implementation complexity manageable.
