摘要： A wireless communication apparatus supports at least a second wireless communication scheme between a first wireless communication scheme and the second wireless communication scheme. The first wireless communication scheme requires that a wireless medium is determined to be busy when a reception level is equal to or greater than a minimum reception sensitivity level of a physical scheme. The apparatus includes a first processing unit and a second processing unit. The first processing unit is configured to set a value lower than a maximum transmission power of the first wireless communication scheme, for a maximum transmission power of the second wireless communication scheme and set a value greater than the minimum reception sensitivity level of the physical scheme, for a carrier sense level, when the second wireless communication scheme is used. The second processing unit is configured to carry out carrier sense using the carrier sense level.

摘要： A radio communication method stores a plurality MAC frames for each of a plurality of destinations. The method decides the longest transmission time of transmission times needed to transmit the plurality of MAC frames to each of the plurality of destinations within a fixed period. The method generates a plurality of physical frames for the plurality of destinations to transmit them at the same time by connecting the plurality of MAC frames and adding additional information to each connected MAC frame so as to be a frame length equivalent to a transmission time equal to the longest transmission time.

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： According to an embodiment, a communication device is provided in a movable body and is wirelessly communicable with a transceiver unit and another movable body. A receiver of the device receives transceiver unit information including traffic-light information that the transceiver unit has transmitted to a predetermined channel. An processing circuitry extracts the traffic-light information corresponding to a running direction of the movable body from the transceiver unit information. A transmitter transmits movable body information of the movable body to the predetermined channel. A processing circuitry controls a transmission timing of the movable body information such that a transmission control period becomes a preset first time. A processing circuitry changes the transmission control period to a second time longer than the first time, when the traffic-light information with respect to the running direction indicates a stopping command, and a speed of the movable body is a preset speed or less.

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.
