a sensor that performs channel sensing in an unlicensed band; and
a transmitter that notifies another communication device of space domain information, as channel occupancy information indicating that channel occupancy is performed when the sensing succeeds,
wherein the transmitter notifies of at least one of:
information about a horizontal angle or elevation angle of the beam transmitted by the communication device, as the channel occupancy information, or
information about polarization of the beam transmitted by the communication device, as the channel occupancy information.
