A method of transmission power control is performed by a radio device along with another radio device being connected to a radio control device, the radio device forming a second cell overlaid with a first cell which is formed by the another radio device and a first frequency band is used. The method comprises monitoring a failure state of the other radio device, and reducing transmission power of radio waves to be transmitted to the second cell when the failure state of the another radio device is detected. |
