MOBILE COMMUNICATION SYSTEM, MOBILE STATION DEVICE, BASE STATION DEVICE, AND ELECTRIC WAVE INTERFERENCE REDUCING METHOD

摘要

Provided is a mobile communication system comprising a first base station device having a first communicatable area, at least one second base station device having a second communicatable area narrower than the first communicatable area and capable of adjusting the output electric power of a transmitting electric wave, and a mobile station device capable of being wirelessly connected with the first base station device or at least one second base station device.  When the mobile station device is wirelessly connected with the first base station device and receives an electric wave which interferes with an electric wave received from the first base station device, the mobile station device transmits a transmitting electric power reduction demanding command to demand the reduction of the output power of the transmitting electric wave, to at least any one of the second base station device, and that of at least one second base station device, which has received the transmitting electric wave reduction demanding command from the mobile station device, reduces the output electric power of the transmitting electric wave.
