User terminal, communication control apparatus, and processor

A first base station comprising:

• a transmitter configured to transmit a first transmission power control parameter and a second transmission power control parameter, wherein
• the first transmission power control parameter is for a single transmission in which radio signals are transmitted from a user terminal only to the first base station, and
• the second transmission power control parameter is for a dual simultaneous transmission in which radio signals are simultaneously transmitted from the user terminal to both the first base station and a second base station, wherein
• the first transmission power control parameter is used by the user terminal to determine first transmission power for the single transmission, the first transmission power being used for transmitting radio signals to the first base station, and
• the second transmission power control parameter is used by the user terminal to determine second transmission power and third transmission power for the dual simultaneous transmission, the second transmission power being used for transmitting a radio signal to the first base station, and the third transmission power being used for transmitting a radio signal to the second base station.

A processor for a user terminal and a memory that stores a program to be executed by the processor, wherein the processor executes:

• a process of receiving, from a first base station, a first transmission power control parameter and a second transmission power control parameter, wherein
• the first transmission power control parameter is for a single transmission in which radio signals are transmitted only to the first base station, and
• the second transmission power control parameter is for a dual simultaneous transmission in which radio signals are simultaneously transmitted to both the first base station and a second base station;
• and
• the processor further executes:
• a process of determining first transmission power for the single transmission based on the first transmission power control parameter, the first transmission power being used for transmitting radio signals to the first base station;
• and
• a process of determining second transmission power and third transmission power for the dual simultaneous transmission based on the second transmission power control parameter, the second transmission power being used for transmitting a radio signal to the first base station, and the third transmission power being used for transmitting a radio signal to the second base station.
