In the application.

技术领域Technical field

本发明涉及通信技术，尤其涉及一种基于业务类型指示的确认方法及装置。The present invention relates to communication technologies, and in particular, to a method and an apparatus for confirming based on a service type indication.

背景技术Background technique

目前，无线局域网(Wireless Local Area Network，简称WLAN)主要采用的标准为电气和电子工程师协会(Institute of Electrical and Electronics Engineers，简称IEEE)802.11系列。其中，WLAN中可以包括多个基本服务集(Basic Service Set，简称BSS)，每个BSS中包括：一个接入点(Access Point，简称AP)和多个与该AP关联的站点(Station，简称STA)。在IEEE标准的802.11ax中引入正交频分多址(Orthogonal Frequency Division Multiple Access，简称OFDMA)技术后，AP可以在同一时刻调度STA在AP指定的资源单元(Resource Unit，简称RU)上发送上行数据，类似地，也可以在同一时刻指示STA在AP指定的资源单元(Resource Unit，RU)上接收下行数据。At present, the standard adopted by the Wireless Local Area Network (WLAN) is the Institute of Electrical and Electronics Engineers (IEEE) 802.11 series. The WLAN may include a plurality of basic service sets (BSSs), and each BSS includes: one access point (AP) and a plurality of stations associated with the AP (Station, referred to as STA). After the Orthogonal Frequency Division Multiple Access (OFDMA) technology is introduced in the IEEE standard 802.11ax, the AP can schedule the STA to send uplinks on the resource unit (Resource Unit, referred to as RU) specified by the AP at the same time. Data, similarly, may also indicate that the STA receives downlink data on a Resource Unit (RU) designated by the AP at the same time.

具体地，针对AP与STA之间交互的业务数据，可以通过AP和STA之间传输业务标识符(Traffic Identifier，简称TID)来指示业务类型，一般地，业务类型(Traffic Category，简称TC)分为视频图像类业务(Video，VI)、语音类业务(Voice，VO)、尽力服务业务(Best-Effort，BE)和背景业务(Background，BK)。以图1为例，一个AP与4个STA关联，若采用传统的业务类型指示方法，AP向每个STA发送下行物理层服务数据单元(Physical Layer Service Data Unit，简称PSDU)，该PSDU中只携带一个TID，一个TID中只能对应一种业务类型。由于4个STA的业务需求、通信环境不同，所以不能保证这4个STA在各自RU上接收的下行业务数据可以同时结束。若某个STA接收完业务数据后，其用于接收数据所使用的RU便会处于空闲状态，可能会导致这4个STA之外的其他STA误判信道空闲后竞争信道，从而对未完成下行业务数据接收的STA产生严重干扰。Specifically, for the service data exchanged between the AP and the STA, the traffic identifier (Traffic Identifier, TID for short) is used to indicate the service type. Generally, the traffic type (Traffic Category, TC for short) It is a video image service (Video, VI), a voice service (Voice, VO), a best effort service (Best-Effort, BE), and a background service (Background, BK). As shown in FIG. 1 , an AP is associated with four STAs. If a traditional service type indication method is used, the AP sends a Physical Layer Service Data Unit (PSDU) to each STA. Carrying a TID, a TID can only correspond to one type of service. Since the service requirements and communication environments of the four STAs are different, it cannot be guaranteed that the downlink service data received by the four STAs on the respective RUs can be simultaneously ended. If an STA receives service data, it is used to receiveThe RU used by the data may be in an idle state, which may cause other STAs other than the four STAs to misjudge the channel after the channel is idle, thereby causing serious interference to STAs that have not completed downlink service data reception.

现有技术中，为了避免干扰，应该保证AP关联的多个STA的业务数据都在相同时间接收完毕，如图1所示，AP在相对于其他STA提前传输完下行数据的STA的业务数据后添加填充比特(padding，简称Pad)。反向地，如图2所示，多个STA向AP传输的业务数据同样添加Pad。In the prior art, in order to avoid interference, it is ensured that the service data of multiple STAs associated with the AP are received at the same time. As shown in FIG. 1 , after the AP transmits the service data of the STA of the downlink data in advance with respect to other STAs, Add padding (padding, abbreviated as Pad). In reverse, as shown in FIG. 2, the service data transmitted by a plurality of STAs to the AP is also added with Pad.

但是，上述Pad实际上就是冗余信息，而且像图1中STA3、STA4有多重业务需求的业务传输，必须等到该STA的全部下行业务数据传输完毕后再发送下一个业务类型的业务数据，反向地，如图2所示，STA向AP发送的上行业务数据也存在同样的问题，即传统的业务类型指示方法会导致大量的资源浪费。However, the above-mentioned Pad is actually redundant information, and the service transmission of the STA3 and STA4 in FIG. 1 has multiple service requirements, and the service data of the next service type must be sent after all the downlink service data of the STA is transmitted. To the ground, as shown in FIG. 2, the uplink service data sent by the STA to the AP also has the same problem, that is, the traditional service type indication method causes a large amount of resource waste.

本发明实施例中，接收方节点可以是AP或STA，同样，发送方节点也可以是AP或STA，如图4所示的传输过程中AP为发送方节点，STA为接收方节点；如图5所示的传输过程中STA为发送方节点，AP为接收方节点，下文中不再赘述。In the embodiment of the present invention, the receiver node may be an AP or an STA. Similarly, the sender node may also be an AP or an STA. In the transmission process shown in FIG. 4, the AP is a sender node, and the STA is a receiver node. In the transmission process shown in FIG. 5, the STA is the sender node, and the AP is the receiver node, which will not be described below.

如图4、图5所示，本发明实施例中发送方节点发送的业务数据包中可以携带多个不同业务类型的业务数据子包，例如，可以携带多个TID。例如，图4、图5中，一个横条表示一个业务数据包，AP向4个STA发送的业务数据包中均可以包括多个业务数据子包，例如图4中，AP向STA1发送的业务数据包中就包括：VO子包、BE子包、BK子包这3个业务数据子包。下述实施例中，针对发送方发送的这种业务数据包进行回复，实现可以一次回复多个不同类型的业务数据子包。As shown in FIG. 4 and FIG. 5, in the embodiment of the present invention, a service data packet sent by a sender node may carry multiple service data sub-packets of different service types, for example, multiple TIDs may be carried. For example, in FIG. 4 and FIG. 5, a horizontal bar indicates a service data packet, and the service data packet sent by the AP to the four STAs may include multiple service data sub-packets, for example, the service sent by the AP to STA1 in FIG. The data packet includes: three service data sub-packets: VO sub-packet, BE sub-package, and BK sub-package. In the following embodiments, the service data packet sent by the sender is replied, so that multiple different types of service data sub-packets can be replied at one time.

图6为本发明提供的基于业务类型指示的确认方法实施例一的流程示意图，如图6所示，该方法包括：FIG. 6 is a schematic flowchart ofEmbodiment 1 of a method for confirming a service type indication according to the present invention. As shown in FIG. 6, the method includes:

S601、接收方节点接收发送方节点发送的业务数据包。其中，该业务数据中携带N种业务类型的k个业务数据子包；N为大于或等于2的正整数，k为大于或等于N的正整数。S601. The receiver node receives the service data packet sent by the sender node. The service data carries k service data sub-packets of N service types; N is a positive integer greater than or equal to 2, and k is a positive integer greater than or equal to N.

S602、接收方节点向发送方节点回复确认消息，该确认消息包括：业务标识符和k个业务标识辅助字段。以告知发送方节点收到了发送方节点发送的N种业务类型的k个业务数据子包。S602. The receiver node sends an acknowledgement message to the sender node, where the acknowledgement message includes: a service identifier and k service identifier auxiliary fields. The sender node is notified that the k service data sub-packets of the N service types sent by the sender node are received.

其中，该业务标识符(TID)指示上述N种业务类型的组合，或者，该TID指示业务类型的个数为N。即具体指示出N种业务类型具体包括哪些业务类型，或者，仅指示出所包括的业务类型的个数。The service identifier (TID) indicates a combination of the foregoing N service types, or the TID indicates that the number of service types is N. That is, it specifically indicates which service types are specifically included in the N service types, or only indicates the number of service types included.

另外，如图3、4所示，发送方节点所发送的多个业务数据子包具有一定的顺序，例如图3中AP向STA3发送的业务数据包中业务数据子包顺序为“VO子包→BE子包→BK子包”，相应地，为了说明这N种业务类型的k个业务数据子包的执行顺序，接收方回复确认消息时，携带的业务标识辅助字段也按照对应的业务数据子包的顺序依次排列。具体实现时，业务标识符辅助字段与业务数据子包一一对应，上述k个业务标识辅助字段按照k个业务数据子包的顺序依次排列，以具体指示出这N种业务类型的k个业务数据子包的组合方式。这样接收方节点就可以通过上述确认消息表示接收到发送方发送的N种业务类型的k个业务数据子包。In addition, as shown in FIG. 3 and FIG. 4, the plurality of service data sub-packets sent by the sender node have a certain order, for example, the service data sub-package in the service data packet sent by the AP to the STA3 in FIG.The order is “VO sub-package→BE sub-package→BK sub-package”. Correspondingly, in order to explain the execution order of k service data sub-packets of the N service types, the service identifier auxiliary field carried by the receiver when replying to the acknowledgement message They are also arranged in the order of the corresponding service data sub-packets. In a specific implementation, the service identifier auxiliary field is in one-to-one correspondence with the service data sub-packet, and the k service identifier auxiliary fields are sequentially arranged in the order of k service data sub-packets to specifically indicate k services of the N service types. The way data sub-packets are combined. In this way, the receiving node can indicate that the k service data sub-packets of the N service types sent by the sender are received through the above confirmation message.

需要说明的是，上述发送方节点、接收方节点可以预先配置好默认采用这样的方式确认业务数据，即发送方节点、接收方节点均预先知道业务标识符和业务标识辅助字段所表达的意义。It should be noted that the sender node and the receiver node may be configured in advance to confirm the service data in such a manner that the sender node and the receiver node know in advance the meanings expressed by the service identifier and the service identifier auxiliary field.

可选地，上述确认消息为块确认(block acknowledgement，简称BA)帧。具体地，BA帧的帧结构如图7所示，包括：“帧控制(frame control)”字段、“时长/用户标识(Duration/ID)”字段、“接收地址(receiver address，简称RA)”字段、“发送地址(transmitter address，简称TA)”字段、“块确认控制(BA Control)”字段、“块确认信息(BA Infomation)”字段以及“帧校验序列(frame check sequence，简称FCS)”字段。Optionally, the acknowledge message is a block acknowledgement (BA) frame. Specifically, the frame structure of the BA frame is as shown in FIG. 7, and includes: a “frame control” field, a “Duration/ID” field, and a “receiver address (RA)”. Field, "transmitter address (TA)" field, "BA Control" field, "BA Infomation" field, and "frame check sequence" (FCS) "Field.

BA帧的“BA Information”字段包括：“每个业务标识(per traffic identifier，简称per-TID Info)”子字段、“块确认起始序列控制(Block Ack Starting Sequence Control)”子字段、以及“块确认比特图(Block Ack Bitmap)”子字段。The "BA Information" field of the BA frame includes: a "per traffic identifier (per-TID Info)" subfield, a "Block Ack Starting Sequence Control" subfield, and " Block Ack Bitmap" subfield.

可选地，上述业务标识符携带在per-TID Info子字段中。具体实现时，参照图7，per-TID Info子字段的16bit中可以有12bit的保留位，这12bit中采用11bit作为关联标识(Association Identifier，简称AID)，剩下1个bit用于表示确认消息(ACK/BA)，per-TID Info子字段的16bit中另外4bit可以作为TID。Optionally, the foregoing service identifier is carried in a per-TID Info subfield. For specific implementation, referring to FIG. 7, there may be 12 bits of reserved bits in the 16 bits of the per-TID Info subfield, and 11 bits are used as the Association Identifier (AID), and the remaining 1 bit is used to indicate the acknowledgement message. (ACK/BA), the other 4 bits of the 16 bits of the per-TID Info subfield can be used as the TID.

本实施例中，发送方节点向接收方节点发送的业务数据包中携带不同业务类型的多个业务数据子包，接收方节点接收到业务数据包后向发送方节点回复确认消息，在确认消息中通过业务标识符以及多个业务标识辅助字段来指示收到的不同业务类型的多个业务，以完成业务数据的确认，实现了可以一次完成多个业务的指示，大大节约了资源。In this embodiment, the service data packet sent by the sender node to the receiver node carries multiple service data sub-packets of different service types, and the receiver node returns a confirmation message to the sender node after receiving the service data packet, and confirms the message. The service identifier and the multiple service identifier auxiliary fields are used to indicate multiple services of different service types received, so as to complete the confirmation of the service data, and the indication that multiple services can be completed at one time is realized, thereby greatly saving resources.

在上述实施例的基础上，可选地，第一种实现方式中，业务标识符的不同值与不同的业务类型组合一一对应。即业务标识符的每个值可以表示一种唯一的业务类型组合。On the basis of the foregoing embodiment, optionally, in the first implementation manner, different values of the service identifiers are in one-to-one correspondence with different service type combinations. That is, each value of the service identifier can represent a unique combination of service types.

具体地，上述业务标识符可以包括多个比特位，该业务标识符的值即由这多个比特位的值组成，但并不以此为限。Specifically, the service identifier may include multiple bits, and the value of the service identifier is composed of values of the multiple bits, but is not limited thereto.

参照图7，业务标识符可以是per-TID Info子字段中的“TID”，该“TID”可以占4个比特(bit)，但不以此为限。如表1所示，该“TID”的4个比特可以表示16个不同的值，每个值表示一种业务类型组合，以4种业务类型(VO、VI、BE、BK)为例，一共有15种不同的业务类型组合，剩余1个TID值可以作为保留位，当然，某些实施场景中，有些业务类型组合并不需要，则可以灵活减少业务类型组合，即可能剩余更多的保留位。以表1为例，其中“1110”表示“VO+VI+BE+BK”的业务类型组合。需要说明的是，表1仅是具体的示例，TID值与业务类型组合的对应关系并不以此例为限。Referring to FIG. 7, the service identifier may be "TID" in the per-TID Info subfield, and the "TID" may occupy 4 bits, but not limited thereto. As shown in Table 1, the 4 bits of the "TID" can represent 16 different values, and each value represents a combination of service types, taking four service types (VO, VI, BE, BK) as an example. There are 15 different combinations of service types, and the remaining one TID value can be used as a reserved bit. Of course, in some implementation scenarios, some service type combinations are not required, so the service type combination can be flexibly reduced, that is, more reservations may be left. Bit. Take Table 1 as an example, where "1110" represents a service type combination of "VO+VI+BE+BK". It should be noted that Table 1 is only a specific example, and the correspondence between the TID value and the service type combination is not limited to this example.

表1Table 1

针对这种业务标识符，上述业务标识符指示所述N种业务类型的组合，具体为：业务标识符当前的值指示上述N种业务类型的组合。以图4为例，STA3发送了包含VO、VI和BE这3种TC的业务数据包，如果采用表1的对应关系，AP接收到包含这3种TC的业务数据包后回复的BA中携带的TID值就为“1010”。For the service identifier, the service identifier indicates a combination of the N service types, and specifically, the current value of the service identifier indicates a combination of the foregoing N service types. As shown in FIG. 4, STA3 sends a service data packet including three types of TCs, VO, VI, and BE. If the corresponding relationship of Table 1 is used, the AP carries the BA that responds after receiving the service data packets of the three TCs. The TID value is "1010".

可选地，第二种实现方式中，上述业务标识符可以包括：多个比特位，每个比特位对应一种业务类型，每个比特位的值用于指示是否存在对应的业务类型。例如，某个比特位与业务类型“VI”对应，该比特位的值为“1”指示存在“VI”，该比特位的值为“0”指示不存在“VI”。与上例类似地，参照图7，仍以per-TID Info子字段中4个bit的“TID”为例，假设第1个bit指示业务类型“VO”、第2个bit指示业务类型“VI”、第3个bit指示业务类型“BE”、第4个bit指示业务类型“BK”，相应地，比特位的值为“1”指示对应业务类型存在，比特位的值为“0”指示对应业务类型不存在，那么，当TID当前的值为“1100”时，则表示此次业务类型的组合为“VO+VI”，当然，并不以此为限，只要每个比特位唯一对应一种业务类型即可。Optionally, in the second implementation manner, the service identifier may include: multiple bits, each bit corresponding to a service type, and the value of each bit is used to indicate whether a corresponding service type exists. For example, a certain bit corresponds to the service type "VI", and the value of the bit is "1" indicating the presence of "VI", and the value of the bit is "0" indicating that "VI" does not exist. Similar to the above example, referring to FIG. 7, the "TID" of the four bits in the per-TID Info subfield is taken as an example, assuming that the first bit indicates the service type "VO" and the second bit indicates the service type "VI". The third bit indicates the service type "BE", and the fourth bit indicates the service type "BK". Correspondingly, the value of the bit is "1" indicating that the corresponding service type exists, and the value of the bit is "0". If the current service type does not exist, then when the current value of the TID is "1100", the combination of the service type is "VO+VI". Of course, it is not limited to this, as long as each bit uniquely corresponds. A business type is OK.

针对这种业务标识符，上述业务标识符指示所述N种业务类型的组合，具体为：业务标识符当前的多个比特位的值指示上述N种业务类型的组合。以图4为例，STA3发送了包含VO、VI和BE这3种TC的业务数据包，AP接收到包含这3种TC的业务数据包后回复的BA中携带的TID值就为“1110”。For the service identifier, the service identifier indicates a combination of the N service types, and specifically, the value of the current multiple bits of the service identifier indicates a combination of the foregoing N service types. As shown in Figure 4, STA3 sends a service data packet containing three types of TCs: VO, VI, and BE. The TID value carried in the BA that the AP responds to after receiving the service data packets of the three TCs is "1110". .

可选地，第三种实现方式中，业务标识符的不同值与业务类型的个数一一对应。即业务标识符的每个值可以表示一个唯一的业务类型的个数。Optionally, in the third implementation manner, different values of the service identifiers are in one-to-one correspondence with the number of service types. That is, each value of the service identifier can represent the number of unique business types.

具体地，上述业务标识符可以包括多个比特位，该业务标识符的值即由这多个比特位的值组成，但并不以此为限。Specifically, the service identifier may include multiple bits, and the value of the service identifier is composed of values of the multiple bits, but is not limited thereto.

与上例类似地，参照图7，仍以per-TID Info子字段中4个bit的“TID”为例，假设由“TID”的前3个bit表示4种业务类型的任意组合的个数，最后一个bit可以作保留位，但并不以此为限，只要是其中任意3个bit的组合即可。具体地，以表2为例：Similar to the above example, referring to FIG. 7, the "TID" of the four bits in the per-TID Info subfield is taken as an example, and the number of any combination of the four service types is represented by the first three bits of the "TID". The last bit can be reserved, but it is not limited to this, as long as it is a combination of any 3 bits. Specifically, take Table 2 as an example:

表2Table 2

TIDTID业务类型business type000000VOVO001001VIVI010010BEBE011011BKBK1001002*TC2*TC1011013*TC3*TC1101104*TC4*TC111111ReservedReserved

“2*TC”表示有2种业务类型，“3*TC”表示有3种业务类型，“4*TC”表示有4种业务类型。以表2的表示方式，当业务标识符要表示2种业务类型时，“TID”的值可以是“100x”，其中x可以是0或1，在此不作限制。"2*TC" means that there are two types of services, "3*TC" means that there are three types of services, and "4*TC" means that there are four types of services. The value of "TID" may be "100x", where x may be 0 or 1, and is not limited herein.

针对这种业务标识符，上述业务标识符指示业务类型的个数为N，具体为：业务标识符当前的值指示业务类型的个数。For the service identifier, the service identifier indicates that the number of service types is N, and specifically, the current value of the service identifier indicates the number of service types.

需要说明的是，并不以上述三种实施方式为限，不同的业务标识符可以区分出多个业务类型即可。It should be noted that, not limited to the foregoing three implementation manners, different service identifiers may distinguish multiple service types.

进一步地，在上述实施例的基础上，上述k个业务标识辅助字段按照k个业务数据子包的顺序依次排列，以指示出这N种业务类型的k个业务数据子包的组合方式，具体为：上述k个业务标识辅助字段按照k个业务数据子包的顺序依次排列，且每个业务标识辅助子段指示对应业务数据子包的业务类型，以及所对应的业务子包的业务类型是否与相邻的下一业务数据子包的业务类型相同。Further, on the basis of the foregoing embodiment, the k service identifier auxiliary fields are sequentially arranged in the order of k service data sub-packets, to indicate the combination manner of k service data sub-packets of the N service types, specifically The k-th service identification auxiliary field is sequentially arranged in the order of k service data sub-packets, and each service identification auxiliary sub-segment indicates the service type of the corresponding service data sub-packet, and whether the service type of the corresponding service sub-package is Same as the service type of the adjacent next service data sub-package.

如图7所示，具体实现时，业务标识辅助字段可以为BA帧的BA information子字段中“‘Block Ack Starting Sequence Control’+‘Block Ack Bitmap’”，但不以此为限。主要信息携带在“Block Ack Starting Sequence Control”中，具体地，“Block Ack Starting Sequence Control”中可以包括4个bit的“分段号(Fragmentation number)”以及12个bit的“起始序列号(Starting Sequence number)”，具体地，“Fragmentation number”的4个bit中，有3个bit表示“业务类型(TC Type)”，另一个bit表示“级联指示(Cascaded Indication)”。“TC Type”这3个bit的值可以跟4种业务类型的业务数据子包一一对应，例如“000”表示VO子包，“001”表示VI子包，“010”表示BE子包，“011”表示BK子包；进而，“Cascaded Indication”可以用来表示对应的业务数据子包的业务类型是否与相邻的下一业务数据子包的业务类型相同，例如，可以用“0”表示与相邻的下一业务数据子包业务类型不同，用“1”表示与相邻的下一业务数据子包业务类型不同，在此不作限制。As shown in FIG. 7 , in the specific implementation, the service identifier auxiliary field may be “Block Ack Starting Sequence Control”+ “Block Ack Bitmap” in the BA information subfield of the BA frame, but is not limited thereto. The main information is carried in the "Block Ack Starting Sequence Control". Specifically, the "Block Ack Starting Sequence Control" may include a 4-bit "Fragmentation number" and a 12-bit "starting sequence".In the "Starting Sequence number", specifically, three of the four bits of the "Fragmentation number" indicate "Traffic Type (TC Type)", and the other bit indicates "Cascaded Indication". The value of the three bits of "TC Type" can correspond to the service data sub-packets of the four service types. For example, "000" indicates a VO sub-package, "001" indicates a VI sub-package, and "010" indicates a BE sub-package. "011" indicates a BK sub-package; further, "Cascaded Indication" can be used to indicate whether the service type of the corresponding service data sub-packet is the same as the service type of the adjacent next service data sub-package, for example, "0" can be used. Indicates that the service type of the next service data sub-packet is different from that of the adjacent next service data sub-packet. The value of "1" indicates that it is different from the adjacent service data sub-packet service type, and is not limited herein.

继续参照图7，举例说明，如图4中，STA3向AP发送了VO、VI和BE三种业务类型的3个业务数据子包，假设AP向STA3回复的BA如果采用表1所示的方式，则BA中的“TID”为“1010”，进而该BA包括连续3个业务标识辅助字段“‘Block Ack Starting Sequence Control’+‘Block Ack Bitmap’”，且第一个“Block Ack Starting Sequence Control”与VO子包对应，其中“TC Type”为“000”，由于相邻的下一业务数据子包是VI子包，与该VO子包的业务类型不同，所以“Cascaded Indication”为0，即“Block Ack Starting Sequence Control”为“0000”，同理，第二个“Block Ack Starting Sequence Control”与VI子包对应，并与相邻的下一业务数据子包的业务类型BE不同，记为“0010”，第三个“Block Ack Starting Sequence Control”与BE子包对应，该BE子包是业务数据包中的最后一个业务数据子包，可以记为“0100”，但不以此为限。本例中，如果采用上述业务标识符的第二种或第三种的实现方式，仅TID的值不同，后续业务标识辅助字段的表示方式均一致，在此不再赘述。With reference to FIG. 7, for example, as shown in FIG. 4, STA3 sends three service data sub-packets of three service types: VO, VI, and BE to the AP, and assumes that the AP replies to STA3 in the manner shown in Table 1. The "TID" in the BA is "1010", and the BA includes three consecutive service identification auxiliary fields "'Block Ack Starting Sequence Control' + 'Block Ack Bitmap'", and the first "Block Ack Starting Sequence Control" Corresponding to the VO sub-package, where the "TC Type" is "000", since the adjacent next service data sub-package is a VI sub-package, and the service type of the VO sub-package is different, "Cascaded Indication" is 0. That is, "Block Ack Starting Sequence Control" is "0000". Similarly, the second "Block Ack Starting Sequence Control" corresponds to the VI sub-package, and is different from the service type BE of the adjacent next service data sub-package. For "0010", the third "Block Ack Starting Sequence Control" corresponds to the BE sub-package, which is the last service data sub-package in the service data packet, which can be recorded as "0100", but not Limit. In this example, if the second or third implementation manner of the foregoing service identifier is used, only the value of the TID is different, and the representation manners of the subsequent service identifier auxiliary fields are the same, and details are not described herein again.

再举例说明，如图4所示的例子中，STA1向AP发送的业务数据包中包括“VO子包→VO子包→BE子包→BE子包”这2种业务类型的4种业务数据子包，AP向STA回复的BA如果采用表2所示的方式，则“TID”的值可以为1000或1001，在此不作限制，进而该BA包括连续4个业务标识辅助字段，与上例类似的，第一个“Block Ack Starting Sequence Control”与VO数据包对应，其中“TC Type”为“000”，且相邻的下一个业务数据子包仍为VO，所以“Cascaded Indication”为1，即“Block Ack Starting Sequence Control”为“0001”，同理，第二个“Block Ack Starting Sequence Control”与VO子包对应，并与相邻的下一个业务数据子包的业务类型BE不同，记为“0000”，第三个“Block Ack Starting Sequence Control”与BE子包对应，并与相邻的下一个业务数据子包的业务类型BE相同，记为“0101”，第四个“Block Ack Starting Sequence Control”与BE子包对应，且该BE子包是业务数据包的最后一个业务数据子包，可以记为“0100”，但不以此为限。For example, in the example shown in FIG. 4, the service data packet sent by STA1 to the AP includes four types of service data: two types of service types: “VO sub-package→VO sub-package→BE sub-package→BE sub-package”. If the sub-packet and the AP reply to the STA are in the manner shown in Table 2, the value of the "TID" may be 1000 or 1001, which is not limited herein. The BA includes four consecutive service identifier auxiliary fields, and the above example. Similarly, the first "Block Ack Starting Sequence Control" corresponds to the VO packet, where "TC Type" is "000", and the next adjacent service data sub-packet is still VO, so "Cascaded Indication" is 1 , ie "Block Ack Starting"The Sequence Control is "0001". Similarly, the second "Block Ack Starting Sequence Control" corresponds to the VO sub-packet and is different from the service type BE of the next adjacent service data sub-packet, and is marked as "0000". The third "Block Ack Starting Sequence Control" corresponds to the BE sub-packet and is the same as the service type BE of the next adjacent service data sub-packet, denoted as "0101", and the fourth "Block Ack Starting Sequence Control" and The BE sub-packet corresponds to, and the BE sub-packet is the last service data sub-package of the service data packet, which can be recorded as “0100”, but is not limited thereto.
