Abstract: There is provided a communication method for a coordinator communication device, including generating a first scheduling element to be used by a first communication device and a second scheduling element to be used by a second communication device; and transmitting the first and second scheduling elements to the first and second communication devices. The second scheduling element includes a second allocation indicating a time-frequency resource allocated to the second communication device. The first scheduling element includes a first allocation indicating a time-frequency resource allocated to the first communication device and optionally includes a first virtual allocation that is a duplicate of the second allocation. The first communication device performs communication in accordance with a first communication system using a first frequency band, and the second communication device performs communication in accordance with the first communication system or a second communication system using a second frequency band that includes the first frequency band.

Abstract: A base station device includes a frame generator circuitry that generates a first training frame used for receive beam training among frames used for beamforming training, a beam controller circuitry that sets a beam used to transmit the first training frame to an omnidirectional mode, a transmitter circuitry that transmits the first training frame at the lowest MCS rate of IEEE 802.11, a receiver circuitry that receives first and second response frames from a wireless terminal device that has received the first training frame after a determined period since transmission of the first training frame, and a frame determiner circuitry that determines whether the first response frame is a response to the receive beam training. In a case where the first response frame is a response to the receive beam training, the beam controller circuitry sets a beam received by the receiver circuitry to a directional beam, and the receiver circuitry receives the second response frame with a directional beam.

Abstract: In a transmission apparatus, signal carrier signal circuity that generates two single carrier signals including a legacy preamble signal, a legacy header signal and an extension header signal respectively. OFDM signal circuity that generates one OFDM signal by performing an IFFT processing on one or more payload signals. Transmission circuity that transmits the two single carrier signals by allocating to a bonding channel which is formed by bonding two adjacent channels used in a bonding transmission scheme and the one OFDM signal by allocating to the bonding channel which is frequency-shifted.
