摘要： An electronic apparatus includes processing circuitry configured to select a first interval to be used for an access to a medium when a first condition is satisfied. The first interval has a fixed length shorter than DIFS (distribute coordination function inter frame space) defined in IEEE802.11 standard. The processing circuitry is also configured to select a second interval to be used for the access to the medium when a second condition different from the first condition is satisfied. The second interval has a fixed length equal to or longer than the DIFS defined in the IEEE802.11 standard. The electronic apparatus also includes wireless circuitry configured to access the medium to transmit a radio wave conforming to a first wireless specification different from the IEEE802.11 standard after the medium is idle for the selected first or second interval.

摘要： 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.

摘要： According to one embodiment, a wireless communication apparatus is provided with first and second determination units. The first unit determines based on a first carrier sense threshold whether busy state or not and specifies a first time when busy state is determined with the first threshold, and determines based on a second carrier sense threshold smaller than the first threshold whether busy state or not and specifies a second time when busy state is determined. The second unit determines, if at least busy state is determined based on the second threshold and the second time precedes a reference time equal to or earlier than the first time, to perform processing for avoiding interference.

摘要： A wireless communication terminal including a transmitter which transmits, to an external device, a frame including n frame sets each including a subheader field, a frame check sequence field, and a frame body field including data, where n is an integer of two or more. The subheader field includes a sequence number field which notifies a sequence number; a more fragment field which notifies whether or not the data is a last fragment; and a frame body length field which notifies a length of the frame body field. A receiver receives, from the external device, a response frame notifying a successively and successfully received maximum sequence number which indicates a highest sequence number among sequence numbers indicated in sequence number fields of frame sets which have been successively and successfully received by the external device among the n frame sets included in the transmitted frame. The receiver receives one response frame per transmitted frame, even if more than two frame sets among the n frame sets have been successfully received.
