Abstract
A user equipment includes a transmission unit that transmits, to a base station, information indicating a specific band combination supported by the user equipment for carrier aggregation and combinations of maximum numbers of Multiple-input and multiple-output (MIMO) layers to be applied to respective component carriers of frequency bands included in the specific band combination, the combinations of the maximum numbers of MIMO layers being supported by the user equipment; and a control unit that applies a default value as the maximum numbers of MIMO layers to be applied, by the user equipment, to the respective component carriers of the frequency bands included in the specific band combination, when a signal indicating the maximum numbers of MIMO layers to be applied, by the base station, to the respective component carriers of the frequency bands included in the specific band combination is not received from the base station.
