1. A communication device comprising:
an acquisition circuit configured to acquire first information for communication in which a first frequency band has been used, the first frequency band being an unlicensed band in which a plurality of communication schemes can be mixed, from a second frequency band different from the first frequency band; and
a communication control circuit configured to control communication in a predetermined communication scheme in which the first frequency band has been used, on the basis of the first information,
wherein the first information includes timing information that enables timings to be shared with other communication devices that use the first frequency band in a communication scheme different from the predetermined communication scheme,
wherein the communication control circuit controls the communication in the predetermined communication scheme in which the first frequency band has been used, on the basis of the timing information,
wherein the timing information is information broadcast using the second frequency band, and
wherein the timing information is information broadcast from a terrestrial broadcasting station device using the second frequency band, the timing information being virtual satellite transmission information generated by imitating information transmitted from a navigation satellite.
