AI Technical Summary

Technical Problem

The challenges in Life Cycle Management (LCM) of UE-side AI/ML models for beam management include unclear intervals for UE inference operations, excessive signaling overhead in reporting inference results, and the lack of mechanisms for the network to understand UE preferences for reporting these results.

Method used

The wireless terminal is configured to transmit information indicating a minimum interval for performing AI/ML model-based beam predictions and to evaluate criteria for triggering reports based on comparisons with previous results, while also transmitting preference information to the network regarding reporting.

Benefits of technology

This approach optimizes the configuration of UE-side AI/ML model reporting, reducing signaling overhead and enabling the network to better manage UE-side AI/ML operations, thereby improving the efficiency and effectiveness of beam management.

Abstract

This radio terminal transmits, to a network, information indicating a minimum interval enabling the execution of an inference operation that uses an artificial intelligence or machine learning (AI / ML) model for generating, on the basis of the results of measuring a second set of a plurality of beams, a beam prediction for a first set of one or more beams. Due to this configuration, it is possible to provide, for example, details related to settings for the inference operation that uses the AI / ML model for the beam predictions.
