Dynamic HARQ Timing for Multi-TRP Data Transmission

The patent applies dynamics by transitioning from fixed HARQ-ACK timing configuration to dynamic indication of multiple PDSCH-to-HARQ_feedback timings through DCI. This allows the system to adapt feedback timing based on actual reception conditions of multiple PDSCHs, reducing feedback delay while maintaining operational simplicity through standardized signaling mechanisms.

The patent changes the parameter of HARQ-ACK timing from a fixed value to multiple configurable timing values indicated via DCI. By introducing multiple PDSCH-to-HARQ_feedback timing parameters (e.g., K2 values) that can be dynamically selected, the system optimizes feedback timing to match actual reception patterns, thereby reducing feedback delay without significantly increasing device complexity.

The patent enables dynamic adaptation of HARQ-ACK timing to actual PDSCH reception patterns through DCI indication. This prevents unnecessary downlink transmissions by aligning feedback timing with actual data reception, thereby reducing wasted downlink transmission resources while maintaining ease of operation through existing signaling frameworks.

The system uses the already-present DCI signaling to self-configure HARQ-ACK timing based on actual PDSCH reception conditions. By leveraging existing control channel resources to indicate multiple timing values, the system optimizes resource usage without requiring additional complex configuration mechanisms, thus reducing wasted downlink resources while maintaining operational simplicity.

The patent makes the DCI signaling serve multiple functions: it not only schedules PDSCH transmissions but also indicates multiple PDSCH-to-HARQ_feedback timing values. This multi-functionality allows the system to reduce feedback delay and improve transmission efficiency by providing flexible timing options within the existing DCI structure, avoiding the need for separate configuration messages and thereby limiting the increase in device complexity.

The patent segments the HARQ-ACK feedback process by introducing multiple distinct timing values (K2) that correspond to different PDSCH reception scenarios. This segmentation allows the system to optimize feedback timing for each specific reception pattern, improving overall transmission efficiency while managing device complexity through structured, modular timing indications rather than a single complex configuration.
