摘要： When a transmission rate of each of lines that transmit data simultaneously between two STAs by using a plurality of radio channels and/or MIMO can be set independently, one data frame is fragmented in accordance with the transmission rates of the respective lines so as to generate a plurality of data packets having the same packet time length and data sizes equal to or smaller than a maximum data size. Those data packets are transmitted simultaneously by using a plurality of radio channels, or one radio channel and MIMO, or a plurality of radio channels and MIMO.

摘要： In a wireless packet communication method for transmitting a plurality of wireless packets simultaneously by using multiple wireless channels determined to be idle by carrier sense, a wireless channel determined to be idle and MIMO, or the multiple wireless channel and the MIMO, a mandatory channel that is always used for transmission is set. The wireless packets are transmitted by using the wireless channel(s) including the mandatory channel only when the mandatory channel is idle. That is, in case of transmitting a plurality of wireless packets simultaneously, transmission is performed by using the wireless channel(s) including the mandatory channel, and transmission is not performed when the mandatory channel is not idle.

摘要： A transmit-side STA transmits a wireless packet using a wireless channel which has been determined to be idle by both a physical carrier sense for determining based on received power whether the wireless channel is busy or idle and a virtual carrier sense for determining the wireless channel to be busy during set transmission inhibition time. At this time, the transmit-side STA sets transmission time used for the virtual carrier sense to a paired wireless channel which is affected by leakage from a transmitting wireless channel. This allows for setting transmission inhibition time to a paired wireless channel even when the paired wireless channel cannot successfully receive due to the effect caused by leakage from the transmitting wireless channel.
摘要翻译：发送侧STA使用无线信道来发送无线信道，该无线信道已经被确定为基于接收到的功率的用于确定的物理载波侦听是空闲的，无论无线信道是忙还是空闲，以及用于确定无线信道的虚拟载波侦听在设置传输禁止时间期间忙。此时，发送侧STA将用于虚拟载波侦听的传输时间设置为受来自发射无线信道的泄漏影响的成对无线信道。这允许即使当成对的无线信道由于从发送无线信道的泄漏引起的影响而不能成功接收时，也可以将配置的无线信道的传输禁止时间设置为一个。

摘要： A plurality of types of available transmission rates to be used for transmission of data packets are individually managed for each receiver terminal. When there are a plurality of data packets to be transmitted onto a transmission buffer and when it is possible to transmit said plurality of data packets simultaneously, the packet sizes representative of the data amounts of the respective data packets are referred to as well as the transmission rates of the respective data packets associated with the receiver terminals. The packet time lengths (transmission times) defined by the packet sizes and transmission rates are checked for the respective data packets. A plurality of data packets whose packet time lengths are approximately equal to each other are selected regardless of their receiver terminals. The transmissions of the plurality of selected data packets are commenced simultaneously by use of a plurality of radio channels.

摘要： A plurality of data packets that contain sequence numbers, respectively, are transmitted simultaneously between two STAs by using a wireless channel and MIMO. An STA receiving the plurality of data packets transmitted simultaneously by using MIMO generates a single ACK packet containing information that corresponds to a sequence number of each data packet successfully received, and transmits the single ACK packet to a transmit-side STA without using MIMO. Thus, a ratio of successful ACK packet receptions to total receptions can be increased. An effect of improving throughput achieved by simultaneous transmission can also be ensured.
