    摘要: A generation device generates a frame to be transmitted to a destination communication apparatus. The frame includes a first separation field, a first MAC protocol data unit (MPDU) following the first separation field, a second separation field following the first MPDU, a third separation field following the second separation field, and a third MPDU following the third separation field. The second separation field includes length information set to a value of zero to indicate no second MPDU directly follows the second separation field. The first MPDU includes a first MAC header, a first data field, and a first frame check sequence (FCS). The first FCS is for detecting an error occurred in at least the first data field. The third MPDU includes a third MAC header, a third data field, and a third FCS. The third FCS is for detecting an error occurred in at least the third data field.

    摘要: A wireless communication apparatus performs bi-directional communication with an initiator. The apparatus is allocated an allocation period for data transmission from the initiator. The apparatus includes means for generating a first physical frame including an acknowledgement frame with respect to data received from the initiator, and generating a second physical frame in which a plurality of transmission data frames addressed to the initiator are aggregated. The apparatus also includes means for transmitting the first physical frame at a first transmission rate and the second physical frame at a second transmission rate, during the allocation period.

    摘要: A radio communication apparatus that performs first radio communication using a first channel among two first channels each having a first channel width, and second radio communication using a second channel having a second channel width that is wider than the first channel width and also having a channel width overlapping with the two first channels. The apparatus includes an interference detection device which detects that interference occurs in the first channel among the two first channels, and a frame generation unit which generates a notification frame that recommends the use of only the first channel width. An instruction unit instructs the frame generation unit to generate the notification frame when the occurrence of interference is detected by the interference detection device. A frame transmission unit transmits the notification frame generated from the frame generation unit in response to the instruction from the instruction unit.

    摘要: A first storage stores a first number of streams which are capable of being demultiplexed by the wireless communication apparatus. A first acquisition unit acquires a second number of streams which are capable of being demultiplexed by a first wireless communication apparatus. A second acquisition unit acquires a third number of sum of streams of communications performed by the wireless communication apparatus and the first wireless communication apparatus. A second storage stores, if the first number of streams exceeds the third number of streams, a difference between the first and third numbers of streams as an allowable number of streams. A determination unit determines that a wireless medium is idle, in the case where a number of streams required for perform a new communication is not more than the allowable number of streams.

    摘要: Broadcast data is divided into a plurality of broadcast channels. Any of the plurality of broadcast channels is placed on a predetermined subcarrier in each of a plurality of main bands such that the placed broadcast channels differ from each other in a same frame and are consecutive in a predetermined order in a frame direction. The subcarriers are converted into a transmit RF signal and the transmit RF signal is transmitted.
