When a terminal (200) is capable of connecting to two relay devices that are adjacent to the terminal, from among a plurality of relay devices, a receiving unit (208) receives signals in a first period and a second period for communication among the plurality of relay stations, which are transmitted from the higher order device to the lower order device toward other terminal devices. An interference removal unit (209) obtains a signal transmitted toward the terminal (200) from the higher order relay device by employing the signals toward the other terminal devices that are received in the first period and the second period and removing a signal toward other terminal devices that is transmitted in a third period for communication between the plurality of relay devices and the terminal device from the lower order device from a signal that is received in the third period.
