AI Technical Summary

Technical Problem

In future radio communication systems like NR, the proper control of multiple semi-persistent CSI (SP-CSI) reports is lacking, leading to potential deterioration of communication throughput and quality.

Method used

Utilizing downlink control information (DCI) to activate and deactivate multiple SP-CSI configurations flexibly, ensuring proper control of SP-CSI reports through higher layer signaling and DCI, and controlling the timing of DCI and SP-CSI report transmission to reduce signaling overhead and load.

Benefits of technology

Enhances communication quality by allowing flexible control of SP-CSI reports, reducing signaling overhead, and improving channel state information acquisition.
