AP sends multi-user and detects trigger, notifies STA1～STA4 to carry out channel measurement and trigger STA1～STA4 is first group of feedback side, and that is, all website is the website feeding back immediately.Specific multi-user visits Survey and comprise in trigger for the channel detection information indication field of STA1～STA4 and STA1～STA4 Multi-user's trigger message indication field, as shown in Figure 7.In addition, AP indicating explicitly or implicitly is anti-immediately The website of feedback, such as the website being located at first 4 in AP explicit instruction channel detection information indication field is vertical The website feeding back.
, in the resource that trigger message indicates, the transmission parameter according to trigger message instruction is parallel for STA1～STA4 Send channel feedback report.And these websites support flexible divided reset method, specifically, AP is The inadequate resource the feeding back immediately channel feedback information whole to carry website of STA1～STA4 distribution, then Local channel feedback information is encapsulated as one or more channel feedback information segmentations and is polymerized by STA1～STA4 Radio frames are become to be fed back, these segmentations can be equal in magnitude or unequal, to adapt to AP distribution Uplink multi-users channel resource.
AP receives the radio frames comprising local channel feedback information, and according to reception condition, sends multi-user's wheel Ask trigger frame, continue triggering STA1～STA4 and send the channel feedback information segmentation not having to send and/or re-transmission Receive incorrect channel feedback information segmentation.Similarly, it is directed to each in multi-user's poll trigger anti- The feedback report of feedback side retransmits or transmission instruction bitmap can notify STA1～STA4 transmission or retransmitted which letter Road feedback information segmentation.
Example IV
AP carries out descending multi-user channel detection process, if the ascending resource distributing to certain feedback website is not enough Cause website cannot send channel feedback etc. reason, then feedback website can send empty feedback frame, notifies AP The reason cannot send, and provide information to help AP to carry out ensuing multi-user's poll trigger process, example As AP can be asked in empty feedback frame to distribute suitable resource, detailed process is as shown in Figure 8：
AP sends multi-user and detects trigger, notifies STA1～STA9 to carry out channel measurement and trigger STA1～STA4 is first group of feedback side.Assume that STA1 cannot send channel feedback, STA2～STA4 can With Normal Feedback.STA1 is due to the fact that have sent empty feedback：
1st, STA1 is limited in one's ability, and channel detection feedback report takes longer for generating.
2nd, STA1 is not detected by detectable signal NDP it is impossible to generate feedback report information.
3rd, the up transmission resource that AP distributes for STA1 is inadequate, and such as bandwidth or transmission duration are inadequate.
4th, the transmission parameter information of the transmission feedback report that AP indicates for STA1 is improper.
Then STA1～STA4 detects in trigger according to multi-user and sends up nothing on the ascending resource of instruction The channel feedback for comprising channel detection result that line frame, wherein STA2～STA4 send, and STA1 sends For empty feedback frame, specifically, the reason empty feedback frame indicates STA1 non-feedback channel information and expectation The operation of AP next step, specifically, when reason is for above-mentioned 1, STA1 can indicate after how long Channel feedback report can be completed it is desirable to AP triggers STA1 after this time again sends channel feedback report； When reason is for above-mentioned 2, then STA1 cannot complete channel detection, and AP sends without continuing triggering STA1 Feedback report；When reason is for above-mentioned 3, it is more that STA1 can send resource request information request AP distribution Resource, can also send that available channel information notifies which channel resource of AP can use.When reason is upper When stating 4, STA1 can indicate the transmission parameter information of desired feedback report.
In addition, the reason STA1 can indicate multiple non-feedback channel information in empty feedback frame is it is possible to refer to Show multiple expectations or the next step operation recommending AP.STA1 can also only indicate the former of non-feedback channel information Cause, does not indicate other information.
AP receives the radio frames of STA1～STA4 transmitted in parallel it is assumed that full detail receives correctly, and AP sends out Existing STA1 send for empty feedback frame it is assumed that STA1 instruction is 3 the reason feedback, and STA1 Have sent resource request information and available channel resource.Then next AP sends multi-user's poll trigger frame, Continue triggering STA1, STA5, STA6 and send pin in channel feedback information, and multi-user's poll trigger frame It is assigned with more channel resources in the trigger message of STA1 to STA1.STA1、STA5、STA6 Transmitted in parallel channel feedback information.AP receives above-mentioned feedback information and continues to send multi-user's poll triggering letter Number, until obtaining the channel feedback information of the STA1～STA9 all wanting to obtain.
Embodiment five
Before carrying out descending multi-user channel detection process, present invention additionally comprises, channel feedback side sends is No support immediately send channel feedback be indicated to channel detection side.Specifically, in order to avoid occurring due to STA Limited in one's ability, the situation that channel detection feedback report takes longer for generating and sends empty feedback occurs, STA Can whether supporting to send immediately the AP that is indicated to of channel feedback, such as STA1 in association process or Send the ability notifying AP itself in other radio frames, inform and itself do not support to send channel feedback immediately, I.e. STA1 cannot function as first group of feedback website.So AP uses multi-user to detect trigger triggering first STA1 would not be allowed to feed back immediately during group feedback website feedback.
If all websites do not support to send immediately channel feedback, descending multi-user detection process can be as figure Shown in 9.AP sends multi-user and detects trigger, and wherein first group feedback website does not comprise any website, AP sends the channel feedback that multi-user's poll trigger obtains channel feedback side.
Embodiment six
AP carries out descending multi-user channel detection process, and detailed process is as shown in Figure 10.AP sends multi-user Detect trigger, notify STA1～STA9 carry out channel measurement and trigger all site STA 1～STA9 stand Feed back, but requirement feedback is not channel feedback information, but do not comprise the empty anti-of channel detection report Feedback frame or acknowledgement frame.It is specially：

STA1～STA9 transmitted in parallel sky feedback frame or acknowledgement frame, wherein send empty feedback frame or acknowledgement frame In indicate at least one of following information：Resource request, available channel information, data volume to be feedback, The transmission parameter of feedback report, whether can be successfully generated the information such as measurement report.
The information that AP provides according to channel feedback side in the empty feedback frame receiving or acknowledgement frame, reasonably enters Row next step operates.For example：
The measurement report of STA1～STA3 generates, and AP sends multi-user's poll trigger and triggers 3 stations Point parallel transmission channels feedback, the channel resource distributing to 3 websites disclosure satisfy that 3 websites in empty feedback The resource request of instruction in frame/acknowledgement frame, or the channel resource of distribution ensure that and be transmitted 3 websites The data volume to be feedback indicating.
STA4 indicates and can not be successfully generated measurement report, then AP is one or more many in following transmission The up transmission of STA4 is not triggered in user's poll trigger.
STA5 indicates the transmission parameter of feedback report, then AP is sent to sending out in the trigger message of STA5 The transmission parameter sending feedback report can be using the value of STA5 instruction.
STA6～STA9 indicates available channel information, for indicating STA6～STA9 can be in which letter Channel feedback information is sent on road resource, then distributes them for these websites during AP distribution uplink channel resources Available channel.
In addition, feedback site STA 1～STA9 can be in empty feedback frame or acknowledgement frame middle finger in said process Show multiple above-mentioned information contenies, so that AP can consider for feedback website distribution uplink multi-users letter Road resource.
