AI Technical Summary

Technical Problem

Existing wireless communication systems face challenges in efficiently monitoring the performance of AI-based CSI compression, particularly in reducing reporting overhead and ensuring accurate feedback, which is crucial for enhancing channel state information reporting in future wireless communication technologies like 6G.

Method used

A UE-sided monitoring mechanism is introduced, where the user equipment (UE) receives a CSI report configuration from a network entity, determines performance metrics based on CSI measurements and inference reports, and transmits these metrics back to the network entity, utilizing a two-sided AI/ML model for CSI compression and reconstruction.

Benefits of technology

This approach reduces reporting overhead and improves the accuracy of CSI feedback by allowing the UE to monitor and report performance metrics directly, thereby optimizing the AI/ML model's performance in channel state information reporting.

Abstract

Presented are a UE, a processor for channel state information (CSI) report for UE-sided monitoring of artificial intelligence (AI) CSI compression. In an example method, the UE receives a first CSI report configuration for monitoring reporting of CSI compression associated with a CSI resource configuration for channel measurement, wherein the first CSI report configuration comprises a report quantity indicating a monitoring metric of CSI compression and an indication of a second CSI report configuration. The UE determines at least one performance metric corresponding to the monitoring metric of CSI compression based on CSI measurement of one or more transmission occasions of the CSI resource configuration of the first CSI report configuration and one or more inference reports of the second CSI report configuration. The UE further transmits a monitoring report comprising the at least one performance metric.
