Abstract
The present invention is designed to enable adequate transmission power control when inter-base station CA is employed. The present invention is designed so that, when inter-base station CA is employed and the transmission power of a user terminal reaches the maximum transmission power, the user terminal executes transmission power control by carrying out power scaling autonomously. For example, the user terminal has a transmission section that transmits an uplink physical channel in each component carrier, and a control section that switches, over time, the component carrier to which the uplink physical channel is transmitted preferentially.
