Artificial intelligence various mode measurements procedure

A wireless transmit/receive unit (WTRU) comprising a processor, a transceiver unit and a storage unit, and configured to:

• receive, from a network, a first message comprising first information indicating a configuration for artificial intelligence/machine learning, AI/ML, model training, and for measurements for AI/ML training, wherein the configuration for AI/ML model training comprises second information indicating any of one or more AI/ML models, one or more AI/ML selection criteria, a training data configuration, a conditional logging configuration, and a conditional training configuration;
• perform, in an idle state, measurements configured for AI/ML model training;
• select an AI/ML model for training based on the first message;
• train the AI/ML model based on the performed measurements;
• and
• in response to an accuracy level of the trained AI/ML model above a configured accuracy threshold level, trigger transition to connected state, and transmit to the network a second message comprising third information indicating an identity of the trained AI/ML model and one or more AI/ML model parameters.
