    • According to one embodiment, there is provided a wireless communication apparatus for making wireless connection in the first connection attempt state wherein a connection request is attempted using a predetermined frequency channel or the second connection attempt state wherein a connection request is attempted using a plurality of frequency channels. A frame generation unit generates a connection request frame which includes the first field for requesting a search of the plurality of frequency channels in response to occurrence of interference, and the second field indicating whether a corresponding frequency channel is a channel wherein occurrence of interference has been detected. A transmission unit transmits the connection request frame using the predetermined frequency channel in the first connection attempt state, and transmits the connection request frame using the plurality of frequency channels in the second connection attempt state.

    • According to one embodiment, a wireless communication apparatus includes a receiving unit, a transmitting unit and a control unit. The receiving unit is configured to receive a first connection request frame indicating a connection request from another apparatus. The transmitting unit is configured to transmit a connection acceptance frame indicating a response to the first connection request frame. The control unit is configured to control the transmitting unit to retransmit the connection acceptance frame until a first acknowledgement frame addressed to the apparatus as a response to the connection acceptance frame is received from the another apparatus, and control the transmitting unit to stop from transmitting the connection acceptance frame if a second acknowledgement frame addressed to the another apparatus as a destination is received or if a second connection request frame addressed to the another apparatus is received.
    • 根据一个实施例,无线通信装置包括接收单元,发送单元和控制单元。 接收单元被配置为从另一设备接收指示连接请求的第一连接请求帧。 发送单元被配置为发送指示对第一连接请求帧的响应的连接接受帧。 所述控制单元被配置为控制所述发送单元重发所述连接接受帧,直到从所述另一装置接收到作为对所述连接接受帧的响应而寻址到所述装置的第一确认帧,并且控制所述发送单元停止发送所述连接接受帧 如果接收到作为目的地的另一设备寻址的第二确认帧或者是否接收到寻址到另一设备的第二连接请求帧,则连接接受帧。

    • According to one embodiment, a wireless communication terminal including a receiver, a first processor, a first storage, a second storage, a second processor, and a transmitter is provided. The receiver receives one physical packet that includes at least one frame body field, a first field including information on a length of the frame body field, a second field used to detect an error of the frame body field, and a sequence number field including a sequence number corresponding to the frame body field. The second storage retains a successively and successfully received maximum sequence number on the basis of a result of the first processor. The transmitter transmits a response frame indicating the successively and successfully received maximum sequence number when the first processor extracts at least one correct frame body.
