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.

Claim (Index 7):
A wireless communication method for use of a wireless terminal device and a base station device that perform wireless communication compliant with IEEE 802.11, the method comprising\n generating a first training frame and at least one second training frame used for receive beam training among frames used for beamforming training for the wireless terminal device by using the base station device; setting a beam used to transmit the first training frame and the at least one second training frame to an omnidirectional beam; transmitting the first training frame and the at least one second training frame at the lowest MOS rate defined in IEEE 802.11 by using the base station device; receiving the first training frame used for the beamforming training by the wireless terminal device using the omnidirectional beam; determining whether the first training frame instructs receive beam training by using the wireless terminal device; changing a receive beam property to a directional beam in a case where the first response frame instructs receive beam training; receiving the at least one second training frame by using the directional beam by using the wireless terminal device; determining a receive beam property of the wireless terminal device by using the at least one received second training frame; generating a first response frame including the receive beam property of the wireless terminal device by using the wireless terminal device; omnidirectionally transmitting the first response frame at the lowest MOS rate defined in IEEE 802.11 by using the wireless terminal device; receiving the first response frame and at least one second response frame from the wireless terminal device by using the base station device after a determined period since transmission of the first training frame from the base station device; determining whether the received first response frame is a response to the receive beam training by using the base station device; setting the receive beam of the base station device to the directional beam in a case where the received first response frame is a response to the receive beam training; and receiving the at least one second response frame by using the base station device using the directional beam.
