Abstract: A method of a first training node may comprise: performing training on a first two-sided AI/ML model using a raw training data set collected for CSI feedback; generating a sequential training data set for sequential training on the first two-sided AI/ML model; performing pruning on the sequential training data set to obtain a reduced sequential training data set; and transmitting, to a second training node, two-sided AI/ML training data information including at least one of the reduced sequential training data set or sequential training data configuration information.
