AI Technical Summary

Technical Problem

In the 5G NR system, PUCCH carrier switching is needed to avoid transmission delay and impact on URLLC performance due to limited uplink resources, but existing methods lack specific guidance on how to perform PUCCH transmission during carrier switching without additional signaling overhead.

Method used

Determine the second time unit for PUCCH transmission on the second carrier based on the first time unit on the first carrier before switching, allowing PUCCH transmission to continue without additional signaling, using predefined rules or DCI indication to ensure seamless carrier switching.

Benefits of technology

Enables normal PUCCH transmission during carrier switching without increasing signaling overhead, ensuring timely and efficient communication in ultra-reliable low latency scenarios.
