AI Technical Summary

Technical Problem

In wireless communication systems that support very high frequency range and ultra-reliable low latency communication services, the prior art is difficult to meet the needs of CSI reporting, especially in frequency range 2 and above, the CSI processing timeline may lead to high latency and inefficient CSI reporting processing.

Method used

By receiving configurations in a user equipment (UE) to report CSI and dividing the CSI report into multiple parts for multiplexing, transmitting the CSI report using multiple transmission timings is ensured that multiple parts of the CSI report are sent at the corresponding transmission timings.

Benefits of technology

Faster and efficient CSI reporting processing is achieved, reducing CSI processing latency, and improving system performance under high frequency range and URLLC services.

Abstract

Apparatus, methods, and systems for channel state information processing and reporting are disclosed. A method (700) includes receiving (705) a configuration from a mobile wireless network at a user equipment ("UE") device to report channel state information ("CSI"). The method (700) includes receiving (710) at least one grant from the UE device to schedule a plurality of transmission opportunities. The method (700) includes, in response to the received configuration and grant, dividing (715) a CSI report into a plurality of parts for multiplexing, each of the plurality of parts being configured to be transmitted at a transmission opportunity in a plurality of transmission opportunities, and transmitting (720) each of the plurality of parts of the CSI report at a corresponding transmission opportunity in the plurality of transmission opportunities.
