Wtru procedures and reporting for nw-side input/output csi mismatch detection for two-sided ai/ml models

Abstract

A wireless transmit receiver unit (WTRU) receives mismatch configuration information for two-sided artificial intelligence machine learning (AIML) to support network-side measurement and detection of mismatch between channel state information (CSI) reconstructed at the network-side and CSI estimated at the WTRU-side. The WTRU transmits to a base station, a test vector in response to a trigger and receives, from the base station, an indication of CSI mismatch based on the transmitted test vector. The WTRU performs a CSI mismatch mitigation method in response to the received indication. The configuration information may include one or more test vector types, a set of test vectors associated with the one or more test vector types, one or more metrics to monitor and one or more mismatch mitigation methods. The trigger to send the test vector may be one of a period of time or an occurrence of a monitored metric exceeding a configured threshold.
