1. A method for controlling power by a user equipment (UE) in a mobile communication system, the method comprising:identifying a total UE transmit power for uplink transmissions in a transmission occasion;
identifying whether the total UE transmit power exceeds a configured maximum output power of the UE in the transmission occasion; and
in case that the total UE transmit power exceeds the configured maximum output power of the UE, adjusting the total UE transmit power by allocating transmit powers to the uplink transmissions according to priorities of the uplink transmissions,
wherein, for operation with first and second uplink carriers, the UE prioritizes power allocation for transmissions on one of the first uplink carrier or the second uplink carrier where the UE is configured to transmit a physical uplink control channel (PUCCH).
