According to one embodiment, a first communication device performing wireless communication with second and third communication devices is provided. The first communication device includes a communication control unit that determines a time period during which communication between the first and second communication devices could interfere with a communication between the first and third communication devices, sets the beginning of a time period during which communication between the first and the third communication devices can occur as a time where the transmission or receipt of a communication between the first and third communication devices will not interfere with a communication between the first and second communication devices, and transmits a coupling request signal including information concerning the time until the beginning of the time period during which communication between the first and third communication devices begins so as to establish communication with the second communication device.
