The present invention is designed to enable appropriate transmission and reception in user terminals even when CA is executed by applying different duplex modes between multiple cells. A user terminal communicates with an FDD cell and a TDD cell by using carrier aggregation, and has a transmitting/receiving section that receives DL signals transmitted from each cell and transmits UL signals to each cell, and a report control section that controls reporting of capability information regarding simultaneous transmission and reception of the DL signals and UL signals in the transmitting/receiving section. The report control section controls reporting of the capability information regarding simultaneous transmission and reception of the transmitting/receiving section with respect to every combination of a frequency band to use in the FDD cell and a frequency band to use in the TDD cell.
