Abstract: A wireless communication device serving as an NG60 WiGig device includes a PPDU generator that generates an MF control PHY PPDU (physical layer protocol data unit) including a legacy preamble, a legacy header, an NG60 header (a non-legacy header), a data field, and identification information indicating that the non-legacy header is included in the PPDU and a transmitter that transmits the generated MF control PHY PPDU.

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.

Abstract: A presentation apparatus includes a controller that includes a first output terminal for outputting a control signal and first to nth light emitters that each include a first input terminal to which the control signal is input and that is each attachable to the controller in a stacking manner and detachable from the controller. The control signal is transferred to the first to nth light emitters in a stacking order via an electrical serial connection.
