Terminal Device HARQ-ACK Feedback Timing Optimization

The patent changes the timing parameters for HARQ-ACK feedback transmission by introducing new timing relationships (e.g., k values) that allow feedback to be transmitted earlier than conventional LTE timing. This parameter change reduces latency while maintaining system compatibility through careful selection of timing values that work within existing frame structures.

The patent introduces dynamic timing adjustment mechanisms where the HARQ-ACK timing can be flexibly configured based on scheduling requests and serving cell conditions. This allows the system to adapt timing dynamically rather than using fixed conventional timing, reducing processing time while managing complexity through standardized dynamic adjustment rules.

The patent segments the HARQ-ACK feedback transmission by associating it with specific serving cells and their respective timing relationships. Each serving cell can have its own timing configuration, allowing independent optimization while maintaining overall coordination. This segmentation enables better resource utilization across cells without requiring complex centralized timing coordination.

The patent creates a universal timing mechanism that works across multiple serving cells by defining common timing relationships and resource allocation rules that apply universally. This multi-functionality allows the same timing framework to serve multiple cells simultaneously, improving resource utilization while avoiding the complexity of cell-specific custom timing schemes.
