Show presence " VI ", the value of the bit is that " 0 " indicates there is no " VI ".With upper example similarly, join
According to Fig. 7, still by taking " TID " of 4 bit in per-TID Info son fields as an example, it is assumed that the 1st bit
Service class indication " VO ", the 2nd bit service class indications " VI ", the 3rd bit indicate business
Type " BE ", the 4th bit service class indication " BK ", correspondingly, the value of bit is " 1 "
Indicate that correspondence type of service is present, the value of bit is that " 0 " indicates that correspondence type of service is not present, then,
When TID current value is " 1100 ", then it represents that this time type of service is combined as " VO+VI ",
Certainly, it is not limited thereto, as long as each bit uniquely corresponds to a kind of type of service.
For this task identifier, above-mentioned task identifier indicates the combination of the N kinds type of service,
Specially：The value of the current multiple bits of task identifier indicates the combination of above-mentioned N kinds type of service.
By taking Fig. 4 as an example, STA3 have sent the business data packet comprising this 3 kinds of TC of VO, VI and BE, AP
The TID values carried in the BA replied after receiving the business data packet comprising this 3 kinds of TC are just
“1110”。
Alternatively, in the third implementation, the different value of task identifier and the number one of type of service
One correspondence.That is each value of task identifier can represent the number of a unique type of service.
Specifically, above-mentioned task identifier can include multiple bits, the value of the task identifier i.e. by
The value composition of this multiple bit, but be not limited thereto.
With upper example similarly, with reference to Fig. 7, still with " TID " of 4 bit in per-TID Info son fields
As a example by, it is assumed that the number of the combination in any of 4 kinds of types of service is represented by front 3 bit of " TID ", most
Latter bit can make reserved bit, but be not limited thereto, as long as the combination of wherein any 3 bit
.Specifically, by taking table 2 as an example：
Table 2
" 2*TC " indicates 2 kinds of types of service, and " 3*TC " indicates 3 kinds of types of service, " 4*TC "
Indicate 4 kinds of types of service.With the representation of table 2, when task identifier will represent 2 kinds of service class
During type, the value of " TID " can be " 100x ", and wherein x can be 0 or 1, and this is not restricted.
For this task identifier, the number of above-mentioned task identifier service class indication is N, specifically
For：The number of the current value service class indication of task identifier.
It should be noted that be not limited with above-mentioned three kinds of embodiments, different task identifier can be with
Distinguish multiple types of service.
Further, on the basis of above-described embodiment, above-mentioned k service identification subsidiary field is according to k

Type, and the type of service of corresponding business attached bag whether with adjacent next business datum attached bag
Type of service is identical.
As shown in fig. 7, when implementing, service identification subsidiary field can be the BA of BA frames
" ' Block Ack Starting Sequence Control '+' Block Ack in information son fields
Bitmap ' ", but be not limited.Main information is carried in " Block Ack Starting Sequence
In Control ", specifically, 4 can be included in " Block Ack Starting Sequence Control "
" fragment number (the Fragmentation number) " and " starting sequence number (Starting of 12 bit of individual bit
Sequence number) ", specifically, in 4 bit of " Fragmentation number ", there are 3
Bit represents " type of service (TC Type) " that another bit represents that " cascade indicates (Cascaded
Indication)”.The value of " TC Type " this 3 bit can be with the business datum attached bag of 4 kinds of types of service
Correspond, such as " 000 " represents VO attached bags, " 001 " represents VI attached bags, and " 010 " represents BE
Attached bag, " 011 " represent BK attached bags；Further, " Cascaded Indication " can be used to represent correspondence
Business datum attached bag the type of service whether type of service phase with adjacent next business datum attached bag
Together, for example, can represent different from adjacent next business datum attached bag type of service with " 0 ", use " 1 "
Represent different from adjacent next business datum attached bag type of service, this is not restricted.
With continued reference to Fig. 7, illustrate, in such as Fig. 4, STA3 have sent VO, VI and BE to AP
3 business datum attached bags of three kinds of types of service, it is assumed that if AP adopts table to the BA that STA3 is replied
Mode shown in 1, then " TID " in BA is " 1010 ", and then the BA includes continuous 3 business
Mark subsidiary field " ' Block Ack Starting Sequence Control '+' Block Ack Bitmap ' ",
And first " Block Ack Starting Sequence Control " is corresponding with VO attached bags, wherein " TC
Type " is " 000 ", as adjacent next business datum attached bag is VI attached bags, with the VO attached bags
Type of service is different, so " Cascaded Indication " is 0, i.e. " Block Ack Starting Sequence
Control " is " 0000 ", in the same manner, second " Block Ack Starting Sequence Control " with
VI attached bags correspondence, and it is different from type of service BE of adjacent next business datum attached bag, " 0010 " is designated as,
3rd " Block Ack Starting Sequence Control " is corresponding with BE attached bags, and the BE attached bags are
Last business datum attached bag in business data packet, can be designated as " 0100 ", but be not limited.
In this example, if using second or the third implementation of above-mentioned task identifier, only TID's
Value is different, and the representation of follow-up business mark subsidiary field is consistent, will not be described here.
Illustrate again, in example as shown in Figure 4, wrap in the business data packet that STA1 is sent to AP
Include 4 kinds of business numbers of " VO attached bags → VO attached bags → BE attached bags → BE attached bags " this 2 kinds of types of service
According to attached bag, if the BA that AP is replied to STA is by the way of shown in table 2, the value of " TID " can
Think 1000 or 1001, this is not restricted, and then the BA includes continuous 4 service identification optional words
Section, first " Block Ack Starting Sequence Control " and VO number similar with upper example
According to bag correspondence, wherein " TC Type " is " 000 ", and adjacent next business datum attached bag is still
VO, so " Cascaded Indication " is 1, i.e., " Block Ack Starting Sequence Control "
For " 0001 ", in the same manner, second " Block Ack Starting Sequence Control " and VO attached bags
Correspondence, and it is different from type of service BE of adjacent next business datum attached bag, " 0000 " is designated as,
3rd " Block Ack Starting Sequence Control " is corresponding with BE attached bags, and with it is adjacent
Type of service BE of next business datum attached bag is identical, is designated as " 0101 ", the 4th " Block Ack
Starting Sequence Control " are corresponding with BE attached bags, and the BE attached bags be business data packet most
Latter business datum attached bag, can be designated as " 0100 ", but be not limited.
