1. A wireless communication device comprising:
- controlling circuitry configured to;
determine one of a first radio frequency band and a second radio frequency band under a first condition for a selection of a data channel used for a communication of data, wherein the first radio frequency band includes a plurality of first candidate channels and has no usage limitation of data communication, the second radio frequency band includes a plurality of second candidate channels and has a usage limitation of data communication, a number of the second candidate channels in the second radio frequency band is less than a number of the first candidate channels in the first radio frequency band, and signal interferences in the second radio frequency band is less than signal interferences in the first radio frequency band;
determine one of the first radio frequency band and the second radio frequency band under a second condition for a selection of a control channel used for a communication of control information on the data channel, wherein the second condition is different from the first condition, and the control channel is different from the data channel;
select the data channel from the first candidate channels when the first radio frequency band is determined for the selection of the data channel;
select the data channel from the second candidate channels when the second radio frequency band is determined for the selection of the data channel;
select the control channel from the second candidate channels when the second radio frequency band is determined for the selection of the control channel; and
select the control channel from the first candidate channels when the first radio frequency band is determined for the selection of the control channel; and
a transmitter configured to periodically transmit a first beacon signal through the data channel and periodically transmit a second beacon signal through the control channel, the second beacon signal including the control information on the data channel.

Abstract
According to one embodiment, a wireless communication device includes: a transmitter configured to transmit a first beacon signal through a first channel and transmit a second beacon signal through a second channel; and controlling circuitry configured to select the first channel from a first radio frequency band and select the second channel from a second radio frequency band. Use of the second radio frequency band is more limited than use of the first radio frequency band.

15. A wireless communication device comprising:
-
a receiver configured to receive a first beacon signal through a data channel used for a communication of data and receive a second beacon signal through a control channel used for a communication of control information on the data channel wherein the data channel is different from the control channel, each of the data channel and the control channel is selected from a plurality of first candidate channels in a first radio frequency band or from a plurality of second candidate channels in a second radio frequency band, the first radio frequency band has no usage limitation of data communication, and the second radio frequency band has a usage limitation of data communication, a number of the second candidate channels in the second radio frequency band is less than a number of the first candidate channels in the first radio frequency band, and signal interferences in the second radio frequency band is less than signal interferences in the first radio frequency band; and controlling circuitry is configured to; determine preferentially the second radio frequency band as a radio frequency band for searching the control channel, check whether the second beacon signal is received through any one of the second candidate channels in the second radio frequency band, determine, when the second beacon signal is received through any one of the second candidate channels in the second radio frequency band, the control channel to the second candidate channel through which the second beacon signal is received in the second radio frequency band, check, when the second beacon signal is received through none of the second candidate channels in the second radio frequency band, whether the second beacon signal is received through any one of the first candidate channels in the first radio frequency band, determine, when the second beacon signal is received through any of the first candidate channels in the first radio frequency band, the control channel to the first candidate channel through which the second beacon signal is received in the first radio frequency band, and specify the data channel based on the second beacon signal received through the determined control channel. - View Dependent Claims (16, 17, 18, 19, 20)
