摘要:
A wireless communication apparatus is disclosed. A transmitting device transmits a first aggregation frame in which first transmission data frames are aggregated. A measuring device measures a number value of retransmission of each of the first transmission data frames. A storage stores a limiting value of the number value of retransmission. A determination device determines whether the number value of retransmission of each of the first transmission data frames exceeds the limiting value. A transmission buffer buffers the first transmission data frames for which it is determined that the number value of retransmission does not exceed the limiting value, and discards the first transmission data frames for which it is determined that the number value of retransmission exceeds the limiting value, of the first transmission data frames. A retransmitting device retransmits the first aggregation frame in which the first transmission data frames buffered in the transmission buffer are aggregated.
摘要:
A wireless communication apparatus for performing wireless communication using a first channel having a first frequency bandwidth, and a second channel formed of both the first channel and a second communication channel, the second communication channel having a frequency bandwidth equal to the first frequency bandwidth. A first generation of a first declaration frame for declaring occupation of the first channel for a specified period, and a second generation of a second declaration frame for declaring occupation of the second communication channel for a specified period after the first declaration frame are generated and transmitted. Transmission timings are set so that the first and second declaration frames are transmitted at the highest priority of all the other frames.
摘要:
A wireless communication system includes first and second wireless terminals capable of performing transmission by at least one of a first transmission scheme and a second transmission scheme. The first wireless terminal performs transmission of a first frame to the second wireless terminal by using the second transmission scheme. The second wireless terminal communicates with the first wireless terminal to notify the first wireless terminal of information associated with a status of the reception of the first frame transmitted from the first wireless terminal by using the first transmission scheme.

摘要:
A communication apparatus generates a single physical frame including a plurality of MAC frames, and transmits the physical frame. The physical frame has variable-length bitmap information comprising bits corresponding to the plurality of MAC frames, respectively, and length information of the bitmap information.
摘要:
A physical frame is generated and transmitted to a destination terminal. In this physical frame, one of a data frame, an acknowledgement frame, and an acknowledgement request frame, and a transmission permission frame which is used in place of a normal Ack frame associated with a delayed Block Ack, and permits the destination terminal to perform piggyback transmission, are aggregated.
摘要:
A communication apparatus includes a receiving device configured to receive a physical frame in which a plurality of MAC frames, each having a sequence number, are aggregated. A reception buffer which stores MAC frames of the physical frame received by the receiving device. A determination device determines whether or not the first MAC frame in the physical frame received by the receiving device has been successfully received. A reception buffer management device determines, when the first MAC frame has been successfully received, a MAC frame to be forwarded to an upper layer, on the basis of the sequence number of the first MAC frame, and extracts the MAC frame from the reception buffer.

A wireless communication apparatus for performing wireless communication using at least one of the first channel having the first frequency band, and the second channel having the second frequency band which is wider than the first frequency band includes a channel search device which executes the first channel search for the bandwidth of the first frequency band and the second channel search for the bandwidth of the second frequency band, and obtains a search result indicating an idle channel, and a determination device which determines a channel to be used on the basis of the search result obtained by the channel search device.
摘要:
A communication apparatus includes a receiving device configured to receive one physical frame in which a plurality of MAC frames are aggregated. This physical frame includes one acknowledgement request frame for the plurality of MAC frames. The apparatus includes an acknowledgement frame forming device configured to form an acknowledgement frame representing reception statuses of the plurality of MAC frames in response to the acknowledgement request frame. The apparatus also includes a transmitting device configured to transmit the acknowledgement frame. This acknowledgement frame includes a compressed acknowledgement frame representing an acknowledgement bitmap having a size equal to a maximum number of MSDUs (MAC Service Data Units) when one MPDU (MAC Protocol Data Unit) corresponds to one MSDU.
