Patent ID: 8908618

Claim:
A wireless communication device, comprising: a first transmitter/receiver which transmits at least one first wireless signal and receives a second wireless signal corresponding to the at least one first wireless signal by a first wireless communication method using a frequency band with a certain bandwidth; a first physical layer processor which decodes the second wireless signal to obtain a frame and encodes a frame of the at least one first wireless signal to be transmitted; and a first MAC layer processor which supplies a control frame generated by embedding a first frame, which is recognizable by the first wireless communication method and a second wireless communication method different from the first wireless communication method, in a MAC header of a second frame, which is recognizable by the first wireless communication method but is not recognizable by the second wireless communication method, to the physical layer processor as the frame of the at least one first wireless signal, wherein the first frame is a CF-End Frame (contention free end frame) including a first field and a second field, each of which is capable of holding a plurality of bits, and the first MAC layer processor generates information indicating transmission permission of the second wireless signal by setting predetermined values in the first and second fields.
