Abstract
Provided is a communication device, even in a case that many communication devices are connected in a radio communication network constituted of a plurality of different radio communication technologies, that suppresses data transmission of one communication technology from delaying due to data transmission situation of another communication device and enables coexistence of different radio communication technologies. A communication device for transmitting and/or receiving a signal using a plurality of radio communication systems, the communication device includes transmitting a signal configured to reserve a first frequency indicating that a radio wave of a prescribed frequency band is used using a first radio communication system among the plurality of radio communication systems; and transmitting, after transmitting the signal indicating that the radio wave is used, a signal configured to request transmission of data to another communication device using a second radio communication system that is different from the first radio communication system.
