A Base Station (BS) device includes: a signal reception quality value identification unit configured to identify, at every preset identification period, a signal reception quality value in an uplink interference-free environment measured for each terminal in a part of radio resource of Full Duplex (FD) transmission radio resources for transmitting only downlink signals; a terminal identification unit configured to identify a particular terminal experiencing uplink interference due to Full Duplex (FD) transmission among terminals using the FD transmission when a value of the uplink interference caused to the particular terminal is larger than or equal to a preset threshold value; a selection unit configured to select an interfering terminal that causes the uplink interference to the particular terminal; and a controller configured to control the FD transmission radio resources allocated to the interfering terminal to reduce the uplink interference which caused to the particular terminal.
