AI Technical Summary

Technical Problem

In the Sidelink-Unlicense (SL-U) system, how to effectively select transmission resources to improve the utilization of COT and the reliability of HARQ-ACK feedback, especially when using Multiple Consecutive Slots transmission (Multiple Consecutive Slots transmission) , MCSt).

Method used

Select multiple SL authorizations through the terminal to ensure that the resource intervals corresponding to different SL authorizations are greater than or equal to the first duration, and divide the continuous time slot resources into multiple resource groups, with each resource group serving as an SL authorization for different TBs. Transmission or transmission of the same TB to ensure continuous resource occupation and HARQ-ACK feedback time.

Benefits of technology

It improves the overall performance of the SL-U system, ensures that the terminal continuously occupies resources in time, improves the reliability of HARQ-ACK feedback, and improves the throughput and reliability of the system.
