Control device, control method, and base station apparatus

A control method of a control device in a communication system that includes a plurality of base station apparatuses each to constitute a cell, and a terminal apparatus to perform wireless communication with the base station apparatus when the terminal apparatus is positioned in the cell, the control device controlling the base station apparatuses, the control method comprising:

• acquiring, from the base station apparatus, an interference value measured when a signal is received from the terminal apparatus by the base station apparatus;
• estimating, when a transmission power of a first terminal apparatus that communicates with a first base station apparatus of the plurality of base station apparatuses is controlled in accordance with a value of a path loss for the first base station apparatus, a maximum given interference amount which is a maximum amount, among given interferences of the first terminal apparatus for an other base station apparatus other than the first base station apparatus;
• and
• acquiring a corrected value for correcting the transmission power of the first terminal apparatus by using the maximum given interference amount, by processor circuitry.

A base station apparatus in a communication system that includes a plurality of base station apparatuses each to constitute a cell, and a terminal apparatus to perform wireless communication with the base station apparatus when the terminal apparatus is positioned in the cell, and that controls a transmission power in accordance with a value of a path loss for the base station apparatus which is communicating with the terminal apparatus, the base station apparatus comprising:

• a memory;
• and
• processor circuitry coupled to the memory and configured to:
• acquire measurement data measured when a signal is received from the base station apparatus by the terminal apparatus;
• and
• estimate, when a transmission power of the terminal apparatus which is communicating with the base station apparatus is controlled, a total sum of path losses for an other base station apparatus of the plurality of base station apparatuses that include a path loss of the terminal apparatus for the other base station apparatus by using the measurement data, and acquire a corrected value for correcting the transmission power of the terminal apparatus by using the estimated total sum of path losses.
