Whether the aggregate frame that the application scenarios of the embodiment of the present invention reply multiple STA for AP simultaneously by M-BA frames is correct Receive, in order to solve the problems, such as that communication reliability is low in the prior art, the embodiment of the present invention provides a kind of data transmission method, connect Access point and website.

Fig. 6 is the flow chart for the data transmission method that one embodiment of the invention provides, as shown in fig. 6, this method is included such as Lower flow：

Step S601：Access point AP sends configured information at least one site STA, and the configured information is used to indicate one In individual TXOP, communication identifier TID maximum number corresponding to the first A-MPDU that STA is sent to AP；

Wherein, the first A-MPDU meets condition：When AP receives an A-MPDU, AP needs to send out at least one STA The first M-BA frame sent includes block corresponding to the first A-MPDU and confirms BA information.So-called first M-BA frame receives in AP After at least one MPDU sent at least one STA, first M-BA frame on time domain direction transmitted by AP, accordingly , the first above-mentioned A-MPDU can be understood as needing AP to respond immediately to the A-MPDU confirmed.

Step S602：AP receives at least one MPDU that STA is sent according to configured information, and at least one MPDU includes first MPDU, in addition to it is at least one of following：At least one 2nd A-MPDU, at least one 3rd A-MPDU and at least one list-poly- Conjunction-media access control protocol data unit S-A-MPDU, so that at least one MPDU alignment transmitted by different STA；

2nd A-MPDU meets condition：When AP receives two A-MPDU, what AP need not be sent at least one STA Any one M-BA frame includes BA information corresponding to the 2nd A-MPDU, and the 3rd A-MPDU meets condition：When AP receives During three A-MPDU, AP needs to send BA information corresponding to the 3rd A-MPDU, and BA corresponding to the 3rd A-MPDU at least one STA Information is without carrying in first M-BA frame.The 2nd above-mentioned A-MPDU can be understood as replying the A- confirmed without AP MPDU, the 2nd above-mentioned A-MPDU can be understood as responding immediately to the A-MPDU of confirmation without AP.

In order that the MPDU that directly transmit of STA can reach temporal alignment, therefore STA can be with above-mentioned TXOP Send at least one 2nd A-MPDU and/or the 3rd A-MPDU；Further, since confirmation corresponding to S-A-MPDU is ACK, should ACK length is shorter relative to BA, therefore STA can send S-A-MPDU in above-mentioned TXOP.

Step S603：AP sends first M-BA frame at least one STA, and first M-BA frame includes：First A-MPDU Corresponding BA information.

First M-BA frame can also include：ACK corresponding to S-A-MPDU, because the 2nd A-MPDU meets condition：When When AP receives two A-MPDU, AP need not include the 2nd A- at least one STA any one M-BA frame sent BA information corresponding to MPDU, the 3rd A-MPDU meet condition：When AP receives three A-MPDU, AP is needed at least one STA sends BA information corresponding to the 3rd A-MPDU, and BA information corresponding to the 3rd A-MPDU is without carrying in first M-BA frame In, therefore first M-BA frame need not include BA letters corresponding to BA information corresponding to the 2nd A-MPDU and the 3rd A-MPDU Breath.

The embodiment of the present invention provides a kind of data transmission method, is limited by configured information in a TXOP, and STA is sent out to AP TID maximum number corresponding to the first A-MPDU sent, so that only needing to include the first A-MPDU pairs in first M-BA The BA information answered, realizes M-BA compression, so as to improve communication reliability.Further, due to sending MPDU between STA When need to reach temporal alignment, therefore, STA can be at least one of following by sending：At least one 2nd A-MPDU, extremely Few 3rd A-MPDU and at least one S-A-MPDU, so as to improve resource utilization.

Alternatively, when first M-BA frame includes three A-MPDU, then this method also includes：AP is at least one STA N-th M-BA frames are sent, n-th M-BA frames include BA information corresponding at least one 3rd A-MPDU, and the N is straight since 2 Untill the AP has sent BA information corresponding to all the 3rd A-MPDU at least one STA.That is, It is used to confirm the 3rd A-MPDU from second M-BA frame.

Alternatively, the first A-MPDU includes the first mark, and first identifies for identifying when the AP receives described first During A-MPDU, it is described that the AP needs first multi-user at least one STA transmissions-block confirmation M-BA frames to include Block corresponding to first A-MPDU confirms BA information；

2nd A-MPDU includes the second mark, and second identifies for identifying when the AP receives the 2nd A-MPDU When, the AP need not include corresponding to the 2nd A-MPDU at least one STA any one M-BA frame sent BA information；

3rd A-MPDU includes the 3rd mark, and the described 3rd identifies for identifying when the AP receives the 3rd A- During MPDU, the AP needs to send BA information corresponding to the 3rd A-MPDU, and the 3rd A- at least one STA BA information corresponding to MPDU is without carrying in first M-BA frame.

Specifically, when STA sends data, can be controlled by service quality (Quality of Service, abbreviation QoS) The confirmation of 2 bits in field processed regular (ACK policy) sets AP to reply the mode of confirmation, for example, if really Rule setting is recognized for the first mark, and first mark can be 00, if that then STA sends is A-MPDU, if regulation AP is correct The A-MPDU is received, it is necessary to carry BA information corresponding to the A-MPDU in first M-BA；If confirm rule setting for the Two marks, second mark can be 10, then it represents that even if AP has correctly received A-MPDU, it is not required that reply this A-MPDU pairs The BA information answered；If it is the 3rd mark to confirm rule setting, the 3rd mark can be 11, then it represents that be carried when AP is received During the A-MPDU of the 3rd mark, BA information corresponding to the A-MPDU is without carrying in first M-BA frame.If STA is sent to AP Be S-A-MPDU, then first M-BA frame includes confirming ACK information corresponding to the S-A-MPDU, and the ACK information only takes up 2 words Section, the block without the homing sequence control comprising 2 bytes and 8 bytes confirms dot chart, therefore can compress first M- BA length.

Such as：Fig. 7 is the data transfer schematic diagram that one embodiment of the invention provides, as shown in fig. 7, AP sends trigger frame, Configured information is carried in the trigger frame, the configured information is used to indicate in a TXOP, the first A-MPDU that STA is sent to AP Corresponding communication identifier TID maximum number is 2, it can be seen that for confirming A-MPDU of the rule for first regular (00) (i.e. the first A-MPDU), each STA is extremely multiple two, if using rule is confirmed, STA1,2,4 due to TID numbers Limitation, it is necessary to supplement filling, cause the waste of resource.But if confirmation rule is make use of, STA1 can additionally send two The A-MPDU (i.e. the 3rd A-MPDU) that the TID that rule is 11 is 5 and 7 is confirmed, even if STA2, which can send out one, confirms that rule is 00 A-MPDU (i.e. the 2nd A-MPDU), STA4 can additionally send one confirm rule for 11 TID be 7 A-MPDU (i.e. the Three A-MPDU), reduce the wasting of resources caused by filling.

Fig. 8 is the flow chart for the data transmission method that another embodiment of the present invention provides, as shown in figure 8, this method includes Following flow：

Step 801：AP receives at least one MPDU that each STA at least one STA is sent；

Step 802：AP sends first M-BA frame at least one STA, and first M-BA frame includes：First A-MPDU pairs The block answered confirms BA information, in addition to：First configured information and/or the second configured information；

Wherein, the first configured information is used to indicate in first M-BA frame, at least one STA, owns TID number summation of communication identifier corresponding to first A-MPDU, or, first configured information is used for indicator to every The individual STA, the maximum of the TID number corresponding to the first A-MPDU；Second configured information is used to indicate institute State in first M-BA frame, at least one STA, communication identifier TID corresponding to all 2nd A-MPDU Number summations, or, second configured information is used for indicator to each STA, described corresponding to the 2nd A-MPDU The maximum of TID number, the first A-MPDU is the A-MPDU by the AP by first M-BA frame acknowledgment, described 2nd A-MPDU is the A-MPDU not by the AP by first M-BA frame acknowledgment；

Step 803：AP sends n-th M-BA frames at least one STA, and n-th M-BA frames include at least one 2nd A- BA information corresponding to MPDU, N believe since 2 up to AP has sent BA corresponding to the 2nd all A-MPDU at least one STA Untill breath.

Likewise, n-th M-BA frames also carry similar to the first configured information included by first M-BA frame and/or Second configured information, such as：Second M-BA frame includes the 3rd configured information and/or the 4th configured information, the 3rd configured information For indicating in second M-BA frame, at least one STA, communication mark corresponding to all 3rd A-MPDU Know TID number summation of symbol, or, the 3rd configured information for indicator to each STA, the described 3rd A-MPDU pairs The maximum for the TID number answered；4th configured information be used for indicate in second M-BA frame, for it is described extremely A few STA, TID number summation of communication identifier corresponding to all 4th A-MPDU, or, the 4th configured information For indicator to each STA, the maximum of the TID number corresponding to the 4th A-MPDU, the 3rd A- MPDU is the A-MPDU by the AP by second M-BA frame acknowledgment, and the 4th A-MPDU is not passed through by the AP The A-MPDU of second M-BA frame acknowledgment；

To sum up, the A-MPDU similar to the first A-MPDU and the 3rd A-MPDU is to pass through the current M-BA frames by the AP The A-MPDU of confirmation, the A-MPDU similar to the 2nd A-MPDU and the 4th A-MPDU are not pass through the current M-BA by the AP The A-MPDU of frame acknowledgment.

Specifically, the above method is that AP sends confirmation corresponding to multiple MPDU by multistep M-BA, i.e. AP is not passed Defeated whole M-BA confirmations, but BA information corresponding to first passing through first the first A-MPDU of M-BA replies, pass through simultaneously First configured information and/or the second configured information indicate BA information corresponding to which MPDU either ACK not reply or which BA information or ACK are had responded to corresponding to MPDU, and other are replied without the confirmation letter replied by retransmiting n-th M-BA Breath, the M-BA for carrying out multistep is replied, therefore referred to as multistep M-BA.

Based on this, Fig. 9 is the M-BA frame structure schematic diagrames that one embodiment of the invention provides, as shown in figure 9, the present invention is implemented Example then defines the first configured information and/or the second configured information, and the first configured information is used to indicate first M-BA frame In, at least one STA, TID number summation of communication identifier corresponding to all first A-MPDU is 4, wherein STA1 is TID1,2, STA2 TID3,4.Or first configured information is used for indicator to each STA, described the The maximum of the TID number corresponding to one A-MPDU be 4, wherein STA1 be TID1,2,5,6, STA2 TID3,4, each Most 4 of STA, but it is in general 6.

Figure 10 is the data transfer schematic diagram that another embodiment of the present invention provides, and as shown in Figure 10, AP triggers 3 STA and entered Row uplink multi-users transmit, and do not limit the number for the TID that each STA can be sent, and STA1 have sent 4 TID A-MPDU, STA2 have sent 3 A-MPDU, and STA3 have sent 2 A-MPDU, and STA4 have sent 3 A-MPDU, 12 altogether, prior art In, will can there are more STA, more TID, here only with this in practice including BA information corresponding to 12 A-MPDU in M-BA Exemplified by, if wanting to shorten the length of M-BA frames, BA information corresponding to TID1,2,3 can be first replied by first M-BA frame, and BA information corresponding to the TID5,6,7 that not yet send is sent by n-th M-BA frames afterwards within the out-of-date time.

Second configured information is used to indicate in first M-BA frame, at least one STA, Suo Yousuo TID number summation of communication identifier corresponding to the 2nd A-MPDU is stated, or, second configured information is used for indicator to each The STA, the maximum of the TID number corresponding to the 2nd A-MPDU.

Alternatively, can also include in above-mentioned M-BA frames：M-BA sequence numbers (Sequence Number, abbreviation SN), are used for Indicate the M-BA frames are which M-BA frames in multistep M-BA.

Alternatively, STA is according to the configured information and first configured information, or according to second configured information Determine whether include confirmation/block confirmation corresponding to all MPDU in first M-BA frame, including：When described STA is determined in the first M-BA frame of the instruction indicated by first configured information, at least one STA, institute There is TID number summation of communication identifier corresponding to the first A-MPDU to be less than and institute is directed to according to determined by the configured information State at least one STA, TID number summation of communication identifier corresponding to all first A-MPDU, it is determined that described first M-BA frames include confirmation/block confirmation corresponding to all MPDU；Or

Therefore, AP is by sending the first configured information and/or the second configured information so that STA can be according to first finger Show that information and/or the second configured information also do not receive corresponding ACK or BA in the presence of some MPDU.It is not regarded as these MPDU It is not correctly received, and may proceed to wait, other M-BA frames is waited within the out-of-date time, until reaching out-of-date time or M- The maximum of BA sequence numbers, it just will be considered that do not receive MPDU is not properly received by AP.

The embodiment of the present invention provides a kind of data transmission method, and AP sends confirmation corresponding to multiple MPDU by multistep M-BA Information, i.e. AP do not transmit whole M-BA confirmations, but first pass through first M-BA and reply BA corresponding to the first A-MPDU Information, while indicate BA information or ACK do not have corresponding to which MPDU by the first configured information and/or the second configured information Reply that either BA information or ACK have responded to corresponding to which MPDU, replying other by retransmiting n-th M-BA does not have back Multiple confirmation, so as to reach the purpose of compression M-BA frames, and then improve the reliability of communication.

Alternatively, first M-BA frame also includes：Communication identifier TID dot charts, described corresponding to the STA TID dot charts include：Identification information corresponding to the A-MPDU, the identification information are the first information or the second information；When When the identification information is the first information, then A-MPDU corresponding to the identification information is the first MPDU；When the mark When information is the second information, then A-MPDU corresponding to the identification information is the 2nd MPDU.Wherein, the first information can be with For 1, the second information can be 0.

Alternatively, before AP sends first M-BA frame at least one STA, in addition to：AP is sent at least one STA Configured information, configured information is used to indicate in a transmission opportunity TXOP, corresponding to the first A-MPDU that STA is sent to AP TID maximum number, so that STA determines first according to configured information and the first configured information, or according to the second configured information Whether include confirmation/block confirmation corresponding to all MPDU in individual M-BA frames.

Or

First M-BA frame also includes：Configured information, the maximum of TID corresponding to the first A-MPDU that STA is sent to AP Number so that STA is according to configured information and the first configured information, or determined according to the second configured information be in first M-BA frame It is no including confirmation corresponding to all MPDU/block confirmation.

No matter where configured information limitation indicates that STA can not be limited in uplink by the configured information System, simply when AP is sending M-BA frames, for each STA, only allow the maximum number for transmitting TID corresponding to the first A-MPDU Corresponding BA information, for the TID not yet replied confirmation, then replied in n-th M-BA frames, Figure 11 is this hair The M-BA frame structure schematic diagrames that bright another embodiment provides, as shown in figure 11, different local of its M-BA frame corresponding to Fig. 9 exist In：TID dot charts are indicated for each STA in Figure 11, and the TID dot charts include：The A-MPDU is corresponding Identification information, the identification information is the first information or the second information；When the identification information is the first information, then institute It is the first MPDU to state A-MPDU corresponding to identification information；When the identification information is the second information, then the mark is believed A-MPDU corresponding to breath is the 2nd MPDU.Wherein, the first information can be 1, and the second information can be 0.

Such as：STA1 TID dot charts are 10100111, indicate that there are 5 TID in STA1 8 TID AP theres really Recognize information, but AP limits maximum TID numbers as 3 simultaneously, then the follow-up confirmation that can only repeat 3 TID, other two TID confirmation will be transmitted in next step M-BA, can be repeated in sequence, for example preceding 3 TID are really Recognize information first to be sent.And in the transmission of M-BA next time, STA1 dot chart can be changed into 00000011, illustrate what is specifically included TID numbers are 2, if the TID numbers of maximum limitation are not less than 2, back can repeat 2 TID confirmation, and STA1 can also know Road oneself have received all confirmations.

Figure 12 is the flow chart for the data transmission method that yet another embodiment of the invention provides, as shown in figure 12, this method bag Include following flow：

Step S1201：AP receives at least one MPDU that each STA at least one STA is sent；

Step S1202：AP sends first M-BA frame at least one STA, and first M-BA frame includes：Corresponding to STA Block confirms dot chart, wherein, STA multiple MPDU share block and confirm dot chart.

Specifically, it is contemplated that when a STA needs to polymerize multiple TID, often each TID information is all without very long, no There can be many MSDU, therefore make STA multiple MPDU share block and confirm dot chart, i.e., multiple TID share block and confirm dot matrix Figure, usual BA dot charts have 8 bytes altogether, 64 bits, at most 64 MSDU can confirmed.It is right that the embodiment of the present invention passes through Each TID BA dot charts are compressed, that is, multiple TID share a BA dot chart, when TID numbers are more Wait, also keep BA dot charts not to be multiplied, or even keep constant, realize the reduction of M-BA length.Figure 13 is another for the present invention The M-BA frame structure schematic diagrames that embodiment provides, as shown in figure 13, wherein the methods of again may be by special TID allows STA to obtain Knowing the BA acknowledgement information fields of back can change, and wherein block confirms that multiple TID starting can be included in homing sequence control Sequence control, if each TID homing sequence is 12 bits, is learnt by TID dot charts and have N number of TID, then share 12N Bit, in addition, the field of general mac frame can be in units of byte, therefore can be by adding M-bit filling bit 12N+ M is 8 multiple.Hereafter block confirms that dot chart can include N number of TID dot chart, wherein each TID includes K=ceil (8* blocks Confirm dot chart size/N), wherein Ceil (X) represents to round up to X.For example, if block confirms that dot chart size is 8 words Section, when 1 TID be present, each TID dot chart size is 8 bytes；When 2 TID be present, each TID dot chart chi Very little is 4 bytes；When there is 3 or 4 TID, each TID dot chart size is 2 bytes；When 5~8 TID be present, often Individual TID dot chart size is 1 byte.

The embodiment of the present invention provides a kind of data transmission method, and wherein STA multiple MPDU share block and confirm dot chart, from And reach the purpose of compression M-BA frames, and then improve the reliability of communication.
