    Abstract: A signal transmission method performed by means of a terminal for performing federated learning in a wireless communication system is provided. According to the signal transmission method, the terminal receives downlink control information (DCI) from a base station, the DCI informing of a specific computation group ID and a modulation and coding scheme (MCS), modulates and encodes data on the basis of the MCS when the specific computation group ID is the same as a computation group ID allocated to the terminal, the data including a parameter related to the federated learning performed by the terminal, and transmits a signal including the data to the base station on the basis of the modulation and encoding.
