AI Technical Summary

Technical Problem

In existing LTE systems, terminal devices lack flexibility in transmitting uplink control information (UCI) and cannot effectively utilize licensed and unlicensed time and frequency resources.

Method used

Terminal devices and network devices can flexibly select target channels for UCI transmission when configured with licensed physical uplink shared channels (GB-PUSCH) and unlicensed physical uplink shared channels (GF-PUSCH), and determine channel priority and selection through indication information in RRC signaling and DCI.

Benefits of technology

It improves the flexibility and resource utilization efficiency of UCI transmission and enhances the wireless resource management and scheduling decision-making capabilities of network equipment.
