A user equipment communicates with a base station using a first RAT and a second RAT, including: a transmission unit to perform uplink transmission using the first RAT and the second RAT; a control unit to, if a sum of transmission powers of the uplink transmission via the first RAT and the second RAT exceeds a predetermined maximum transmission power, reduce the transmission power of the uplink transmission via the second RAT. If the sum exceeds a maximum transmission power and the transmission unit fails to transmit random access preamble via the second RAT and re-transmits the random access preamble, or if dynamic power sharing is not supported and the random access preamble is not transmitted via the second RAT in a slot where an uplink transmission via the first RAT is scheduled, the control unit changes transmission power control for the re-transmitted random access preamble from normal control.
A terminal that communicates with a plurality of base stations in a dual connectivity using a first Radio Access Technology (RAT) and a second RAT, the terminal comprising:
