Original Abstract Submitted

A beam transmission device transmits a directional beam toward a beam reception device in a wireless communication system. The main signal generation unit generates a main signal. A control signal generation unit periodically generates a control signal related to maintaining communication with the beam reception device. A signal multiplexing unit multiplexes the main signal and the control signal. A divergence angle adjustment unit sets a target divergence angle to a first divergence angle in a period in which the control signal is not included in the multiplexed signal, and sets the target divergence angle to a second divergence angle larger than the first divergence angle in a period in which the control signal is included in the multiplexed signal. A beam control unit changes a divergence angle of the beam modulated by the multiplexed signal to the target divergence angle.
