Multi-TRP HARQ Grouping to Prevent Process Ambiguity

The patent segments the 16 HARQ processes into multiple groups, where each group is dedicated to a specific TRP. This segmentation allows parallel processing of HARQ processes across different TRPs, eliminating the stop-and-wait problem that occurs when all processes are shared. By dividing the HARQ process pool into TRP-specific subsets, the system can simultaneously manage multiple transmissions without contention, thereby improving data transmission rate and reducing waiting time.

The patent introduces a TRP identifier as an intermediary element that works together with the HARQ process number to uniquely identify each HARQ process. Instead of relying solely on the HARQ process number, the system combines it with TRP-specific identification information. This intermediary mechanism resolves the ambiguity that arises when the same HARQ process number is used by different TRPs, while maintaining the simplicity of HARQ process identification within each TRP's context.

The patent implements dynamic HARQ process group management, where the grouping and allocation of HARQ processes to TRPs can be flexibly configured and adjusted. Rather than using fixed, static groupings, the system dynamically assigns HARQ processes to TRP groups based on current transmission requirements. This dynamic approach allows the system to optimize transmission efficiency while managing complexity through adaptive resource allocation, enabling efficient handling of varying traffic patterns without requiring overly complex static configurations.
