In one implementation, above-mentioned steps S1320 can include:

The STA be in the F-RTS-PLL trigger frame it is specified, need to return if appropriate for carrying out to described complete double In the case that work AP sends the STA of the data sending processing of data, which confirms itself if appropriate for the progress data transmission Processing；

If being confirmed as being appropriate for the data sending processing, reply to the full duplex AP for indicating that the STA is suitable Close the RPT-P frame for carrying out the data sending processing；

If being confirmed as being not suitable for carrying out the data sending processing, reply to the full duplex AP for indicating the STA Be not suitable for carrying out the RPT-N frame of the data sending processing.

In the present embodiment, full duplex AP can also need to return if appropriate for progress by F-RTS-PLL trigger frame come specified For sending the STA of the data sending processing of data to full duplex AP, therefore full duplex AP can also pass through F-RTS-PLL trigger frame To specify, a half-duplex receives STA and one or more needs are returned if appropriate for the STA for carrying out data sending processing.

Wherein, if STA is to need to return the STA if appropriate for data sending processing is carried out, which can be used full duplex AP specified RU returns itself if appropriate for progress data sending processing to full duplex AP.

In one implementation, above-mentioned duplex communication method may also include that

According to the intensity of the F-CTS frame received, determine whether itself is the STA for being appropriate for the data sending processing.

In the present embodiment, if STA is to need to return the STA if appropriate for data sending processing is carried out, which can basis What is received receives the intensity for the F-CTS frame that STA is sent by half-duplex to determine itself if appropriate for progress data sending processing. If it is determined that then the STA can send to full duplex AP and report certainly, and wherein this is reported certainly itself to be appropriate for data sending processing Announcement is to indicate that the STA is appropriate for the report of data sending processing, and report corresponds to RPT-P frame certainly for this.It is on the contrary, however, it is determined that be Itself be not suitable for carrying out data sending processing (needing to send comprising simultaneously no data), then the STA can be sent to full duplex AP negates Report, wherein the negative report is to indicate that the STA is not suitable for carrying out the report of data sending processing, which corresponds to RPT-N frame.

In one implementation, above-mentioned steps S1320 can include:

In the case where the STA other than the STA is STA specified in the F-RTS-PLL trigger frame, STA confirmation Itself is if appropriate for the data sending processing for carrying out sending data to the full duplex AP；

If being confirmed as being appropriate for the data sending processing, reply to the full duplex AP for indicating that the STA is suitable Close the REQ-T frame for carrying out the data sending processing.

In the present embodiment, even if STA is not STA specified by F-RTS-PLL trigger frame, which can also be used RARU to come The transmission processing itself being appropriate for for sending data to full duplex AP is reported to full duplex AP.Wherein, which can be used RARU sends to full duplex AP and reports certainly, and affirmative report is to indicate that the STA is appropriate for for sending number to full duplex AP According to data sending processing report, this certainly report correspond to REQ-T frame.
