Terminal UCI Multiplexing Priority Segmentation

The patent divides uplink control information into multiple priority levels (first priority and second priority). PUCCH resources are segmented into different sets based on priority, allowing the terminal to select appropriate resources for each priority level independently. This segmentation simplifies resource management by organizing complex resources into structured groups while enabling efficient multiplexing of different UCI types with different priorities in the same PUCCH transmission.

The patent configures multiple PUCCH resource sets that can serve multiple functions. Each resource set can handle different priority levels of UCI, and the same resource set structure is reused across different scenarios (HARQ-ACK, CSI, SR). This multi-functionality approach ensures reliable transmission for different priority levels while avoiding the need to create entirely separate resource pools for each UCI type, thus optimizing resource utilization.

The patent applies different multiplexing rules locally based on priority. When HARQ-ACK (first priority) and CSI reports (second priority) collide, the system selectively multiplexes them based on their priority levels and specific conditions. This localized quality approach allows efficient resource utilization by permitting multiplexing in appropriate cases while maintaining clear, manageable procedures through priority-based decision rules.
