    Abstract: A variable shifter includes: a plurality of shifters that cyclically shift input data having a plurality of bits or cyclically shifted data; and a control unit that selects a shift amount for each of the plurality of shifters in accordance with a predetermined cyclic shift amount. The number of types of the predetermined cyclic shift amount is smaller than the number of bits in the input data, each shifter selects one of a plurality of shift amounts in accordance with the predetermined cyclic shift amount, and the plurality of shift amounts have a combination of shift amounts that differ from one shifter to another.

    Abstract: A communication apparatus includes: control circuitry that controls transmission/reception of a first control frame and a first data frame used for communication with another communication apparatus, and controls transmission/reception of a second control frame and a second data frame used for communication with the another communication apparatus; first radio circuitry that performs radio communication of the first control frame and the first data frame using a first omni-directional antenna; and second radio circuitry that performs radio communication of the second control frame and the second data frame using a second directional antenna. When the first radio circuitry receives, from the another communication apparatus, a WSA frame including information on the radio communication using the second radio circuitry among a plurality of the first control frames, the control circuitry determines not to perform an association procedure between the communication apparatus and the another communication apparatus based on the WSA frame.

    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.
