Base station and method

A base station that performs wireless communication with user equipment, the base station comprising:

• a path loss calculation unit that calculates a path loss at the user equipment;
• a first target receiving power calculation unit that calculates first target receiving power based on the path loss and a first parameter, wherein the first parameter is used by the user equipment that transmits user data in a predetermined sub-frame through an uplink shared channel when the user equipment controls transmission power, and the first target receiving power is for the user equipment that transmits the user data in the predetermined sub-frame through the uplink shared channel when the user equipment controls the transmission power;
• a difference calculation unit that calculates a difference between the first target receiving power that has been calculated by the first target receiving power calculation unit based on the path loss and a second target receiving power that is to be used by the user equipment when the user equipment controls the transmission power, the user equipment transmitting the user data through the uplink shared channel at every constant interval;
• a second parameter calculation unit that calculates a second parameter by subtracting the difference calculated by the difference calculation unit from the first parameter;
• and
• a notification unit that reports the second parameter that has been calculated by the second parameter calculation unit,
• wherein the first target receiving power calculation unit calculates the first target receiving power such that the first target receiving power becomes greater as the path loss becomes smaller.
