UE Processing Time for Repeated DCI PDSCH HARQ-ACK Timing

The patent applies preliminary action by pre-configuring multiple parameters (K1, K2, K3 values) and processing time determination rules before the actual communication occurs. The UE is provided with a set of predefined processing time values and selection criteria based on PDCCH candidate properties, search space set configurations, and CORESET parameters. This allows the UE to determine the correct processing time by referencing pre-established tables and rules rather than calculating it in real-time, thereby reducing the complexity of processing time determination while maintaining the reliability benefits of DCI repetition.

The patent applies parameter changes by dynamically selecting processing time values based on changing conditions related to PDCCH candidates. The UE determines which processing time parameter to use by evaluating properties of the PDCCH candidates (such as their association with different search space sets, CORESET configurations, and temporal relationships). This allows the system to adjust the processing time parameter according to the specific characteristics of the repeated DCI scheduling information, thereby maintaining robustness while optimizing the processing time for HARQ-ACK feedback.

The patent applies dynamics by making the processing time determination adaptive rather than fixed. The UE dynamically selects the appropriate processing time value based on the specific properties of the PDCCH candidates and their associated DCI repetitions. This dynamic approach allows the system to extend processing time only when necessary (e.g., when PDCCH candidates are associated with different search space sets or have specific temporal relationships), while using shorter processing times when the conditions allow, thereby maintaining accuracy when needed while preserving throughput otherwise.
