要約
(EN)

The present invention is designed so that multiple UL signals of varying RATs are transmitted properly in non-stand-alone radio communication systems. A user terminal has a transmission section that transmits a first uplink (UL) signal of a first radio access technology (RAT) and a second UL signal of a second RAT, at different times, and a control section that controls switching between a first time, which is used to transmit the first UL signal using a first UL carrier of the first RAT, and a second time, which is used to transmit the second UL signal using a second UL carrier of the second RAT.
