Wireless communication device and communication method thereof

A wireless communication device, comprising:

• each of a plurality of transmitting/receiving units which simultaneously performs a plurality of wireless communications by a first wireless communication method using a plurality of carrier waves included in frequency bands with a certain bandwidth;
• a plurality of physical layer processors each corresponding to each of the plurality of transmitting/receiving units, respectively, each of which decodes each of received signals different from each other received by the transmitting/receiving units to obtain a frame and encodes the frame, which includes a transmitted signal corresponding to the received signal;
• and
• a MAC layer processor, which divides the frame into a value corresponding to a number of the transmitting/receiving units used in the wireless communication, sets identical destination to each of the frames of which destination is identical, and then supplies the frame to the corresponding physical layer processor,
• wherein the frame is a first control frame, which is recognizable by the first wireless communication method but is not recognizable by a second wireless communication method different from the first wireless communication method, and
• the MAC layer processor embeds a second control frame, which is recognizable by the first wireless communication method and a second wireless communication method different from the first wireless communication method to a MAC header of the first control frame.

A wireless communication method, comprising:

• embedding a first control frame supporting a first wireless communication method and a second wireless communication method different from the first wireless communication method in a MAC header of a second control frame supporting the first wireless communication method but not supporting the second wireless communication method;
• transmitting the second control frame to a first terminal by the first wireless communication method;
• judging whether an address of itself is set in the second control frame when the first terminal may receive the second control frame;
• and
• executing a process corresponding to the first control frame when judging that the address is the address of itself.
