Abstract: Techniques are described for communicating datasets, between wireless devices and network nodes, to train artificial intelligence (AI) and/or machine learning (ML) models, which can be used in both training and inference stages, to improve system performance. An example method for wireless communication includes receiving, by a wireless device, a dataset from a network node, wherein the dataset comprises a plurality of data samples and is associated with a first information. In another example, the example method further includes transmitting, to the network node, a request for the dataset.
