HARQ Feedback Encoding for Multi-TB Scheduling Overlap

The patent applies preliminary action by pre-configuring multiple HARQ feedback transmission modes (first mode for PUCCH, second mode for PUCCH+SPS PDSCH, third mode for R-PDCCH) before actual transmission. The terminal and base station agree on these modes in advance through system information or RRC signaling, eliminating the need for frequent dynamic configuration during operation. This reduces signaling overhead while maintaining the ability to adapt to different transmission scenarios.

The patent implements dynamics by enabling the terminal to dynamically select among pre-configured HARQ feedback transmission modes based on current transmission conditions. The terminal determines which mode to use according to the actual transmission scenario (e.g., whether SPS PDSCH is received, whether R-PDCCH is detected), allowing the system to adapt to changing conditions without requiring frequent base station reconfiguration commands.

The patent applies segmentation by dividing HARQ feedback transmission into different time resources based on the transmission mode. For example, in the second mode, HARQ feedback for SPS PDSCH and dynamic PDSCH are transmitted in different time slots. This segmentation of time domain resources prevents overlap between feedbacks for different TBs, allowing multiple TBs to be transmitted simultaneously without feedback collision.

The patent uses another dimension by introducing time domain resource differentiation as an additional dimension for organizing HARQ feedback transmission. Instead of trying to handle all feedbacks in the same time resource, the patent distributes them across different time slots or uplink resources, effectively adding a time dimension to resolve the overlap problem while maintaining high data transmission productivity.
