Abstract
To enable high-speed learning of an antenna directionality to be used for millimeter-wave communication, there is provided a communication device including a first radio communication unit capable of radio communication in accordance with a first communication method, and a second radio communication unit capable of radio communication in accordance with a second communication method using a higher frequency band than the first communication method, in which, upon receiving an instruction signal instructing to learn a beam directionality, the first radio communication unit determines a reception start time point of a beam reference signal based on the instruction signal, and the second radio communication unit starts reception of the beam reference signal from the reception start time point determined by the first radio communication unit and determines a parameter value for specifying an optimum beam pattern based on the received beam reference signal.
