    Abstract: According to one embodiment, an electronic apparatus includes a transmitter circuitry and a receiver circuitry. The transmitter circuitry is configured to; transmit a first frame to a first terminal, and transmit a second frame to a second terminal when a first period elapsed after transmission of the first frame. The receiver circuitry is configured to receive a third frame including acknowledgement information of the first frame from the first terminal when the first period elapsed after transmission of the first frame. A duration of the second frame is set as equal to or greater than a difference between a duration of the third frame and a duration of the first frame.

    Abstract: According to one embodiment, an electronic apparatus includes a transmitter circuitry, a receiver circuitry, and a processing circuitry. The transmitter circuitry transmits a first data frame including first data to a destination apparatus. The receiver circuitry receives first acknowledgment information indicative of a reception state of the first data included in the first data frame. The receiver circuitry receives second acknowledgment information indicative of a reception state of the first data included in a second data frame. The second data frame is transmitted from another electronic apparatus to the destination apparatus. The processing circuitry determines whether the first data frame is retransmitted, based on at least one of the first and second acknowledgment information.

    Abstract: According to one embodiment, a wireless communication device includes a receiver and a transmitter. The receiver receives a first frame in a predetermined frequency band. The transmitter transmits a second frame in the predetermined frequency band at a same time as receipt of the first frame. The transmitter transmits control information that controls a transmission timing of a third frame that is a response frame to the second frame. The transmitter transmits a fourth frame that is a response frame to the first frame, at a timing according to the control information.

    Abstract: According to one embodiment, an electronic apparatus includes a receiver and a transmitter. The receiver is configured to receive, from a first wireless apparatus, a first physical frame including a destination address receivable by a second wireless apparatus different from the electronic apparatus. The transmitter is configured to transmit, to the first wireless apparatus, a first response frame including first information regarding the first physical frame, if the first physical frame is successfully received. A transmission period of the first response frame at least partially overlaps with a transmission period of a second response frame including second information regarding the first physical frame received by the second wireless apparatus.
