A base station device includes a central unit; and a distributed unit. The distributed unit includes a first processor configured to form beams in plural directions by using plural antenna elements; and transmit and receive a data signal addressed to a terminal device. The central unit includes a second processor configured to select a first beam and a second beam set, by using: relevant information on the beams, the relevant information being notified by the distributed unit that forms the beams; and reception quality of the beams in the terminal device; cause the distributed unit to transmit a reference signal by application of a beam group formed of: one or more beams in the second beam set; and the first beam; and select a beam group to be applied to the data signal, by using a reception state of the reference signal from the terminal device in a predetermined interval.
