A user terminal performs dual connectivity communication with a first base station and a second base station. The user terminal has a controller that performs a process of transmitting data belonging to a split bearer to the first base station via a first transmission path that passes through the first base station and via a second transmission path that passes through the second base station. When performing the process of transmitting the data to the first base station, the controller autonomously distributes the data to the first transmission path and the second transmission path without relying on an instruction from the first base station.
