具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。
本申请的方案主要应用于无线局域网，尤其是应用于多链路传输场景。如图1所示，为本申请适用的一种通信系统的结构示意图，该通信系统100包括多链路发送端设备11和多链路接收端设备12，多链路发送端设备11和多链路接收端设备12(统称为“多链路设备”)之间通过N条链路通信，N为正整数。其中，多链路设备工作的频段可以为以下任一个频段：1GHz、2.4GHz、5GHz、6GHz以及高频60GHz的全部或者一部分，等等。如图2所示的多链路传输场景示意图，多链路发送端设备可以包括一个或多个接入点(access point，AP)(也可以称为接入点多链路设备(access point multi-link device，AP MLD))，则多链路接收端设备可以包括一个或多个站点(station，STA)(也可以称为非接入点多链路设备(non-access point multi-link device，NON-AP MLD))；或者，多链路发送端设备可以包括一个或多个STA，则多链路接收端设备可以包括一个或多个AP。
其中，如图3所示的多链路设备的结构示意图，本申请实施例中的AP MLD和NON-AP MLD在结构上可以包括：媒体接入控制层(media access control，MAC)和物理层(physical，PHY)。其中，MAC层又分为高MAC(high MAC)层和低MAC(low MAC)层。具体地，AP MLD中的多个AP共有一个AP high MAC，每个AP对应一个AP low MAC；NON-AP MLD中的多个STA共有一个STA high MAC，每个AP对应一个STA low MAC。AP MLD中的每个AP的AP PHY通过链路与对应的NON-AP MLD中的一个STA的STA PHY通信。
当一个发送端设备需要建立一个低时延业务时，可以通过一个数据流规格元素(traffic specification element，TSPEC element)告知接收端设备该低时延业务的具体QoS需求。然而，该数据流规格没有包括对所需满足的丢包率的指示。而对于无线系统，很难在满足时延要求的情况下保证零丢包率。
有鉴于此，本申请提供了一种业务指示方案，发送端设备生成业务质量需求信息，该业务质量需求信息包括丢包率指示信息，且发送端设备将该业务质量需求信息发送给接收端设备，从而接收端设备可以根据业务质量需求信息来决定是否同意该低时延业务的建立。如果同意建立该低时延业务，则需要在满足时延要求的同时最小化丢包率。
如图4所示，为本申请实施例提供的一种业务指示方法的流程示意图，该方法可以包括以下步骤：
S101.发送端设备生成业务质量需求信息，该业务质量需求信息包括丢包率指示信息。
本实施例中的业务可以是低时延业务，发送端设备向接收端设备发送数据流规格元素，告知接收端设备该低时延业务的业务质量需求信息。由于对于无线系统，很难在满足时延要求的情况下保证零丢包率，但可以在满足低时延的同时最小化丢包率。因此，本实施例中，业务质量需求信息还包括丢包率指示信息，该丢包率指示信息用于指示可接受的最大丢包信息。该发送端设备是多链路发送端设备中的其中一个发送端设备；该接收端设备是多链路接收端设备中的其中一个接收端设备。举例说明，该发送端设备可以是AP，则该接收端设备是STA；或者，该发送端设备可以是STA，则该接收端设备是AP。
如图5所示，该业务质量需求信息对应的数据流规格元素包括：
元素标识(element ID)：用于标识该元素是哪一个元素。举例说明，该元素标识占用1个字节；
长度(length)：用于指示该元素所占字节数目。举例说明，该长度占用1个字节；
通信标识符比特位图(traffic identifier bitmap)：用于指示该元素对应于哪些通信标识符(traffic identifier，TID)。其中，TID可以是0～7，也可以是0～15，或者8～15。举例说明，该通信标识符比特位图占用1个字节；
传输方向(direction)：指示该通信流的方向。00表示上行；10表示下行；01表示直连链路；11表示上下行双向。举例说明，该传输方向占用1个字节；
最小服务间隔(minimum service interval)：指示该通信流任意两个服务期之间的最小间隔。举例说明，该最小服务间隔占用4个字节；
最大服务间隔(maximum service interval)：指示该通信流任意两个服务期之间的最大间隔。举例说明，该最大服务间隔占用4个字节；
不活动间隔(inactivity interval)：指示该通信流没有数据包到达的最小间隔。举例说明，该不活动间隔占用4个字节；
挂起间隔(suspension interval)：指示该通信流被挂起的最小间隔。举例说明，该挂起间隔占用4个字节；
服务开始时间(service start time)：指示服务的开始时间。举例说明，该服务开始时间占用4个字节；
最小数据速率(minimum data rate)：指示在媒体接入控制(media access control，MAC)层服务访问点位置所对应的最小数据速率。举例说明，该最小数据速率占用4个字节；
平均数据速率(mean data rate)：指示在MAC层服务访问点位置所对应的平均数据速率。举例说明，该平均数据速率占用4个字节；
突发大小(burst size)：指示该通信流的最大突发大小。举例说明，该突发大小占用4个字节；
时延上限(delay bound)：指示该通信流允许的最大时延。举例说明，该时延上限占用4个字节；
丢弃时限(discard age)：指示对应媒体接入控制服务数据单元(media access control service data unit，MSDU)的最大生命期，超过该生命期发送端需丢弃该MSDU。举例说明，该丢弃时限占用2个字节。
在一个实现中，丢包率指示信息包括可接受的最大丢包数量和业务数据包参考数量。因此，该业务质量需求信息对应的数据流规格元素还包括：
可接受的最大丢包数量(maximum discarded MSDU count)：用于指示对应低时延业务在 给定最大时延下可接受的最大丢包数。举例说明，该可接受的最大丢包数量占用4个字节，则可接受的最大丢包数的范围可以是0～2 32。在另外的示例中，该最大丢包数也可以是一个最大丢包范围。例如，预先设定多个最大丢包范围与索引之间的对应关系，发送端设备和接收端设备均存储该对应关系，则该可接受的最大丢包数量可以为上述索引值，可以节省信令开销；
最大丢包范围与索引之间的对应关系的一个示例如下表1所示：
表1
索引 可接受的最大丢包数的范围
0 0～100
1 101～200
… …
业务数据包参考数量(measurement count)：用于指示用于统计丢包率的参考测量数，即发送端设备实际发送的数据包数量。举例说明，该业务数据包参考数量可以占用4个字节，则该业务数据包参考数量的范围可以是0～2 32。
接收端设备接收到上述可接受的最大丢包数量和业务数据包参考数量，则可以计算出发送端设备可接受的最大丢包率为：可接受的最大丢包数量/业务数据包参考数量。
在另一个实现中，如图6所示，丢包率指示信息包括可接受的最大丢包率和业务数据包参考数量。因此，该业务质量需求信息对应的数据流规格元素还包括：
可接受的最大丢包率(maximum discarded MSDU rate)：用于指示对应低时延业务在给定最大时延下可接受的最大丢包率。该可接受的最大丢包率＝可接受的最大丢包数量/业务数据包参考数量。举例说明，可以预先设定多个最大丢包率与索引之间的对应关系，发送端设备和接收端设备均存储该对应关系，则该可接受的最大丢包率可以为上述索引值。
可接受的最大丢包率与索引之间的对应关系的一个示例如下表2所示：
表2
索引 可接受的最大丢包率
0 5％
1 10％
… …
业务数据包参考数量：其含义同上面的描述。
接收端设备根据实际接收到的业务数据包和业务数据包参考数量，可以计算出实际丢包率，然后判断是否在上述可接受的最大丢包率之内。
进一步地，该业务质量需求信息对应的数据流规格元素还可以包括触发报告相应的参数(triggered reporting parameters)：
是否开启基于平均丢包率的触发发送业务质量需求信息的指示信息(triggered report enable)：用于指示是否开启基于平均丢包率的触发测量报告。举例说明，该指示信息占用1比特，该1比特取值为“1”时，表示开启基于平均丢包率的触发测量报告；该1比特取值为“0”时，表示关闭基于平均丢包率的触发测量报告。关闭基于平均丢包率的触发测量报告，是指发送端设备在接收到接收端设备发送的请求时，才发送测量报告给接收端设备。
平均丢包率的阈值(discarded threshold)：用于指示触发测量报告的平均丢包率阈值。该 阈值一般小于上述可接受的最大丢包数量。举例说明，上述是否开启基于平均丢包率的触发发送业务质量需求信息的指示信息用于指示关闭基于平均丢包率的触发测量报告时，则该平均丢包率的阈值对应的比特可以保留或者不出现。
基础延迟范围(Bin 0range)：表示传输时延(transmit delay)直方图的第一个直方条(Bin0)的延迟范围，即时延位于0<＝Delay<B0的MSDU数目。其它直方条(Bin i)是基于该基础延迟范围得到的。
进一步地，该业务质量需求信息对应的数据流规格元素还可以包括：
是否为高可靠性业务的指示信息：即通过该指示信息进一步指示该低时延业务是否为高可靠性业务。高可靠性业务对低时延的要求更高。举例说明，该指示信息可以为1比特，例如，该1比特取值为“1”，则指示该业务是高可靠性业务；该1比特取值为“0”，则指示该业务不是高可靠性业务。
业务的最大的时延抖动：通过该信息用于指示发送端设备要求该低时延业务的时延抖动不能超过该最大的时延抖动。可以用若干比特指示该业务的最大的时延抖动。
是否采用备份传输模式的指示信息：该指示信息用于指示发送端设备和/或接收端设备是否采用备份传输模式。备份传输模式是指对一个MSDU来说，在发送端设备没收到接收端设备的成功接收响应(acknowledgement，ACK)之前，可以通过一条或者多条链路传输该MSDU的多个备份；或者，在接收端设备没收到发送端设备的ACK之前，可以通过一条或者多条链路传输该MSDU的多个备份。举例说明，该指示信息可以为1比特，例如，该1比特取值为“1”时，表示可以采用备份传输模式；该1比特取值为“0”时，表示不采用备份传输模式。
期望的信道接入方式的指示信息：期望的信道接入方式可以是增强分布式信道接入(enhanced distributed channel access，EDCA)、基于上行链路的触发(trigger-based link)信道接入。其中，EDCA是一种较常用的随机接入方式；基于上行链路的触发信道接入是指发送端设备发送触发指示，则接收端设备发送上行数据。该指示信息可以为1比特，其比特取值与期望的信道接入方式的对应关系可以是：“0”表示期望的信道接入方式为EDCA，“1”表示期望的信道接入方式为基于上行链路的触发信道接入。
是否需要建立受限的服务期(restricted service period)的指示信息：受限的服务期是指在该受限的服务期内只能用于传输该低时延业务，不能用来传输其它业务，以避免其它业务对低时延业务的干扰，减少低时延业务的时延。对于受限的服务期有两种建立方式：一种是利用目标唤醒时间(target wake time，TWT)来建立，另一种是通过静默元素(quiet element)来建立。该指示信息可以为1比特，该1比特取值为“1”时，表示需要建立受限的服务期；该1比特取值为“0”时，表示不需要建立受限的服务期。
S102.发送端设备向接收端设备发送业务质量需求信息。
S103.接收端设备接收到该业务质量需求信息，并根据业务质量需求信息，确定业务质量需求。
接收端设备接收到该业务质量需求信息，解析并获取该业务质量需求信息，以便了解接收端设备的业务质量需求。进一步地，可以在业务传输过程中，当业务质量不满足该业务质量需求时，向发送端设备进行反馈。
根据本申请实施例提供的一种业务指示方法，发送端设备生成业务质量需求信息，该业务质量需求信息包括丢包率指示信息，且发送端设备将该业务质量需求信息发送给接收端设备，从而接收端设备可以根据业务质量需求信息来决定是否同意该低时延业务的建立。 如果同意建立该低时延业务，则需要在满足时延要求的同时最小化丢包率。
为了更好地满足低时延业务的业务质量需求，发送端设备可以向接收端设备发送业务质量测量报告，以告知当前低时延业务所达到的业务质量。然而，目前没有多链路场景下，多链路发送端设备如何发送业务质量测量报告的方案，多链路接收端设备无法确定多条链路中每条链路的业务质量。
有鉴于此，本申请提供一种业务指示方案，多链路发送端设备通过在业务质量测量报告中包括链路指示信息和链路的业务质量信息，该链路指示信息用于指示承载业务的多条链路，该链路的业务质量信息包括承载业务的多条链路中每条链路上丢失的媒体接入控制服务数据单元的数量，从而使得对端可以根据业务质量测量报告可以准确地确定多链路中每条链路的业务质量，提高了业务传输的可靠性。
如图7所示，为本申请实施例提供的又一种业务指示方法的流程示意图，该方法可以包括以下步骤：
S201.多链路发送端设备生成业务质量测量报告。
通过多条链路承载/传输业务，可减少业务的包时延。在业务传输过程中，多链路发送端设备获取承载业务的多条链路中每条链路的业务质量，生成业务质量测量报告。
在本实施例中，该业务质量测量报告包括链路指示信息和链路的业务质量信息。该链路指示信息用于指示承载业务的多条链路，多链路场景，承载业务的可以是所有链路，也可以是部分链路，通过该链路指示信息指示实际承载业务的多条链路。该链路的业务质量信息包括承载业务的多条链路中每条链路上丢失的MSDU的数量(MSDU lost count)，丢失的MSDU的数量是指多链路发送端设备发送了MSDU，但是没有收到多链路接收端发送的成功接收响应/块确认(acknowledgement/block acknowledgement，ACK/BA)，或者收到ACK/BA但是显示接收错误。
在一个实现中，如图8所示，该链路指示信息包括承载业务的多条链路的链路数量(number of links)和承载业务的多条链路中每条链路的链路标识符(link ID)。
从而，该业务质量测量报告包括：
承载业务的多条链路的链路数量：用于指示当前承载该低时延业务的链路数量；
承载业务的多条链路中每条链路的链路标识符：即MSDU lost count对应的链路标识符：
链路的业务质量信息包括承载业务的多条链路中每条链路上丢失的MSDU的数量(MSDU lost count)：若承载业务的多条链路的链路数量为N，则包括N个MSDU lost count，N为正整数；
进一步地，该业务质量测量报告还包括：
元素标识(element ID)：用于标识该元素是哪一个元素。举例说明，该元素标识占用1个字节。
长度(length)：用于指示该元素所占字节数目。举例说明，该长度占用1个字节。
通信标识符比特位图(traffic identifier bitmap)：用于指示该元素对应于哪些通信标识符(traffic identifier，TID)。其中，TID可以是0～7，也可以是0～15，或者8～15。举例说明，该通信标识符比特位图占用1个字节。
业务质量测量报告的实际测量起始时间(actual measurement start time)：是指如果是触发的测量报告，则指触发条件成立的时刻。例如，可以是触发时刻的定时同步功能(timing synchronization function，TSF)值。触发条件成立是指前述实施例中实际平均丢包率大于或 等于平均丢包率阈值，则触发发送测量报告；
承载业务的多条链路上成功发送的媒体接入控制服务数据单元的总数量(transmitted MSDU count)：是指多链路发送端设备成功发送并收到多链路接收端设备发送的ACK/BR的MSDU的数量；
承载业务的多条链路上丢弃的媒体接入控制服务数据单元的总数量(MSDU discarded count)：是指多链路发送端设备因超时或者超过重传次数而丢弃的MDSU的数量；
承载业务的多条链路上发送失败的媒体接入控制服务数据单元的总数量(MSDU failed count)：是指多链路发送端设备因超过重传次数而丢弃的MSDU的数量；
承载业务的多条链路上多次重传的媒体接入控制服务数据单元的总数量(MSDU multiple retry count)：是指多链路发送端设备成功传输且超过一次重传的MSDU的数量；
承载业务的多条链路的平均传输时延(average transmit delay)：是指承载业务的多条链路中每条链路的时延之和的平均值，该平均传输时延表示多链路发送端设备的传输时延；
承载业务的多条链路中每条链路上未接收到确认的次数：即承载业务的多条链路中每条链路ACK/BR的失败次数；
承载业务的多条链路中每条链路上收到重叠的基本服务集(overlapping basic service set，OBSS)帧的次数；
承载业务的多条链路中每条链路的信道负载：例如承载业务的多条链路中每条链路的信道为忙的比例；
基础延迟范围：表示传输时延(transmit delay)直方图的第一个直方条(Bin 0)的延迟范围，即0<＝Delay<B0的MSDU数目；
位于至少一个延迟范围内的承载业务的多条链路中媒体接入控制服务数据单元的总数量，即Bin i：即时延落在2^(i-1)*B0<＝Delay<2^i*B0的MSDU数目，Bin i是基于上述基础延迟范围得到的。在图8中，i为1～5。
业务质量测量报告中的上述各个参数均可用于表征承载该低时延业务的多条链路的业务质量。业务质量测量报告可以包括上述各个参数，也可以包括上述多个参数中的部分参数。
在另一个实现中，如图9所示，为另一种业务质量测量报告的格式示意图。与图8不同，在图9中，该业务测量报告包括：
链路指示信息，该链路指示信息采用比特位图实现，比特位图的第一值指示承载业务的多条链路。举例说明，该多链路场景包括link1～link4共5条链路，比特位图的比特取值为“1”指示承载业务的链路。该链路指示信息的比特位图为“11001”，则表示链路1、链路2和链路5为承载业务的链路；
承载业务的多条链路中每条链路上丢失的MSDU的数量，其含义与图8所述相同。对应上述比特位图为“11001”，该MSDU lost count重复3次。
该业务测量报告包括的其他参数可以与图8所述相同。
举例说明，上述业务质量测量报告包括在一个元素(element)中。
多链路发送端设备也可以对其它参数进行测量，该参数的测量报告携带在一个element中发送。
S202.多链路发送端设备向多链路接收端设备发送业务质量测量报告。
多链路发送端设备可以通过承载业务的任一条链路向多链路接收端设备发送业务质量测量报告，也可以通过未承载业务的链路发送上述业务质量测量报告。
S203.多链路接收端设备接收到业务质量测量报告，根据该业务质量测量报告，确定承载业务的多条链路中每条链路的业务质量。
多链路接收端设备接收到业务质量测量报告，可以获取承载业务的多条链路中每条链路的业务质量，如果该低时延业务的业务质量较差，可以准确地确定出是哪条链路导致该低时延业务的业务质量较差。
进一步地，多链路接收端设备在确定承载业务的多条链路中每条链路的业务质量后，对于业务质量低于该低时延业务的业务质量需求的链路，可以采取相应的操作，以进一步改善该条链路上承载该低时延业务的业务质量。具体地，一种方式是AP之间可以选择进行通信标识符与链路(TID-to-link)的映射协商，使得多条链路对应一个TID，以降低该业务的时延；另一种方式是，给业务质量低于该低时延业务的业务质量需求的链路建立相应的受限服务期，使得在该受限服务期内只能传输该低时延业务，以避免其它业务对该低时延业务造成干扰；等等。
其中，对于TID-to-link映射协商，一种是通过TID-to-link映射来指示每条链路是开启(enable)还是关闭(disable)。例如，如果没有TID映射到某条链路，则该链路关闭；相反，如果任意一个TID映射到该链路，则称该链路是开启的，AP MLD和non-AP MLD可以通过开启的链路进行传输。
对于TID-to-link映射协商，响应方存在以下三种响应方式：
方式1，如果该TID-to-link映射指示只包括关闭一条或者多条链路时，则响应方必须接受该TID-to-link映射方案或者这些链路被关闭；
方式2，如果该TID-to-link映射指示包括只包括开启一条或者多条链路时，则响应方可以接受也可以拒绝该TID-to-link映射方案；
方式3，如果该TID-to-link映射指示既包括关闭一条或者多条链路，也包括开启一条或者多条链路时，则响应方可以接受也可以拒绝该TID-to-link映射方案；
此外，对于上述方式1～方式3，如果该TID-to-link映射指示包括关闭一条或者多条链路时，可选地请求方指示该关闭操作是不是强制的，即要求响应方是否必须关闭所述链路。
也可以是，对应上述方式3，对于TID-to-link映射协商，如果该TID-to-link映射指示既包括关闭一条或者多条链路，也包括开启一条或者多条链路时，可选地请求方指示该关闭操作是不是强制的，即要求响应方是否必须关闭所述链路。
根据本申请实施例提供的又一种业务指示方法，多链路发送端设备通过在业务质量测量报告中包括链路指示信息和链路的业务质量信息，该链路指示信息用于指示承载业务的多条链路，该链路的业务质量信息包括承载业务的多条链路中每条链路上丢失的媒体接入控制服务数据单元的数量，从而使得对端可以根据业务质量测量报告准确地确定多链路中每条链路的业务质量，提高了业务传输的可靠性。
如图10所示，为本申请实施例提供的又一种业务指示方法的流程示意图，该方法可以包括以下步骤：
S301.多链路发送端设备生成业务质量需求信息，该业务质量需求信息包括丢包率指示信息。
通过多条链路承载/传输业务，可减少业务的包时延。该实施例中，多链路发送端设备生成该业务的业务质量需求信息，该业务承载在多链路上。生成业务质量需求信息的具体实现可参考图4所示实施例的步骤S101。
S302.多链路发送端设备向多链路接收端设备发送业务质量需求信息。
多链路发送端设备通过任一链路向多链路接收端设备发送业务质量需求信息。
S303.多链路接收端设备接收到业务质量需求信息，并根据业务质量需求信息，确定业务质量需求。
该实施例与前述实施例不同的是，为了更好地满足低时延业务的业务质量要求，多链路发送端设备在发送了业务质量需求信息之后，多链路发送端设备还可以进一步获取每条链路的业务质量，并向多链路接收端设备发送业务质量测量报告，以使得多链路接收端设备可以了解每条链路的业务质量。
S304.多链路发送端设备生成业务质量测量报告。
该业务质量测量报告包括链路指示信息和链路的业务质量信息，所述链路指示信息用于指示承载业务的多条链路，所述链路的业务质量信息包括所述承载业务的多条链路中每条链路上丢失的媒体接入控制服务数据单元的数量。
该步骤的具体实现可参考图7所示实施例的步骤S201。
S305.多链路发送端设备向多链路接收端设备发送业务质量测量报告。
该步骤的具体实现可参考图7所示实施例的步骤S202。
S306.多链路接收端设备接收到业务质量测量报告，根据该业务质量测量报告，确定承载业务的多条链路中每条链路的业务质量。
该步骤的具体实现可参考图7所示实施例的步骤S203。
进一步地，多链路接收端设备在确定承载业务的多条链路中每条链路的业务质量后，对于业务质量低于该低时延业务的业务质量需求的链路，可以采取相应的操作，以进一步改善该条链路上承载该低时延业务的业务质量。具体地，一种方式是AP之间可以选择进行通信标识符与链路(TID-to-link)的映射协商，使得多条链路对应一个TID，以降低该业务的时延；另一种方式是，给业务质量低于该低时延业务的业务质量需求的链路建立相应的受限服务期，使得在该受限服务期内只能传输该低时延业务，以避免其它业务对该低时延业务造成干扰；等等。
根据本申请实施例提供的一种业务指示方法，多链路发送端设备生成业务质量需求信息，该业务质量需求信息包括丢包率指示信息，且多链路发送端设备将该业务质量需求信息发送给多链路接收端设备，从而多链路接收端设备可以根据业务质量需求信息来决定是否同意该低时延业务的建立。如果同意建立该低时延业务，则需要在满足时延要求的同时最小化丢包率；且多链路发送端设备通过在业务质量测量报告中包括链路指示信息和链路的业务质量信息，该链路指示信息用于指示承载业务的多条链路，该链路的业务质量信息包括承载业务的多条链路中每条链路上丢失的媒体接入控制服务数据单元的数量，从而使得对端可以根据业务质量测量报告可以准确地确定多链路中每条链路的业务质量。
如图11所示，为本申请实施例提供的一种业务指示方法的流程示意图，该方法可以包括以下步骤：
S401.多链路发送端设备向多链路接收端设备发送测量请求。相应地，多链路接收端设备接收该测量请求。该测量请求包括请求测量的链路指示信息。
目前定义了很多无线测量请求(radio measurement request)类型，例如，信道负载(channel load)测量，空闲信道评估(clear channel assessment，CCA)测量，等等。即该无线测量请求用于请求测量信道负载或进行空闲信道评估等。
对于多链路场景，一种方式可以是每条链路都进行一次无线测量请求/响应帧交互，以对每条链路进行测量。然而，这种方式信令开销大。

在一个示例中，AP或者AP MLD发送频谱测量请求帧(spectrum measurement request frame)或者是无线测量请求帧(radio measurement request frame)，请求STA或者Non-AP MLD进行transmit stream/category测量。

当TID字段的B0为1时，则表示所测量的是某个SCSID所对应的业务流，SCSID的值会携带在流标识字段中；如果B0为0，则表示测量的是某个TID所对应的业务流或者业务类别。
从而，通过重新定义transmit stream/category measurement request/report中的TID字段，使得可以复用现有的transmit stream/category measurement request/report来实现对某个SCSID的业务流进行测量。
在又一个示例中，AP或者AP MLD发送频谱测量请求帧或者是无线测量请求帧，请求STA或者Non-AP MLD进行transmit stream/category测量。
其中，频谱测量请求帧的帧格式如图14所示。
其中，测量请求元素的格式如图15所示。
其中测量类型会设置为transmit stream/category measurement所对应的索引号。当测量类型设置为transmit stream/category measurement所对应的索引号时，测量请求的格式如图16所示。
对于测量请求中的可选的子元素，当可选的子元素中包括触发报告子元素(triggered reporting subelement)，触发报告子元素的格式如图21所示，包括：

当在optional subelement中携带有triggered reporting subelement且traffic identifier字段中携带的是SCSID时(即traffic identifier字段的B0位被置为1)，如果trigger condition中PDR比特置1，则triggered reporting subelement中除了trigger conditions字段、trigger timeout字段和MSDU count字段外，其他字段均为保留字段。
STA或者Non-AP MLD接收到基于发送流/类别测量的该波谱测量请求帧时，对某个SCSID所对应的业务流、或者某个TID所对应的业务流或业务类别进行相应类型的测量。 STA或Non-AP MLD向AP或者AP MLD发送波谱测量响应帧(spectrum measurement response frame)，其格式如图18所示。

其中，报告原因字段又包括以下字段：平均触发(average trigger)、连续触发(consecutive trigger)、延迟触发(delay trigger)、PDR触发(PDR trigger)和保留字段。该PDR触发字段占用一个保留比特，用于指示该发送流/类别测量报告是因为PDR小于目标值而触发的。
当流标识字段中携带的是SCSID时，可以利用服务质量免竞争轮询丢失计数字段来携带传输的MSDU的个数(MSDU delivery count)，其用于指示发送端成功在所要求的时延上限(delay bound)下发送的MSDU个数。其中，时延上限携带在相应的TSPEC元素中。
另外，当站点侧为non-AP MLD时，可以在发送流/类别测量报告中携带一个新定义的多流测量报告子元素(multi-link measurement report subelement)，用于携带承载该被测量的业务的相关的每条链路(per-link)信息。新定义的多流测量报告子元素的格式如图23所示，包括：

根据本申请实施例提供的一种业务指示方法，多链路发送端设备通过在无线测量请求中携带请求测量的链路指示信息，指示请求测量的链路，从而，多链路接收端设备可以根据该链路指示信息对请求测量的链路进行测量并上报测量报告，避免对多链路的每条链路都进行一次测量请求/测量响应帧的交互，节省了信令开销，提高了测量效率。
上述对本申请实施例提供的方案进行了介绍，可以理解的是，业务指示装置(比如，AP，STA，AP MLD或者NON-AP MLD)，为了实现上述功能，其包含了执行各个功能 相应的硬件结构和/或软件模块。本领字段技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，本申请能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。

客户端(例如STA)可以向服务端(例如AP)发送流分类服务(stream classification service，SCS)请求帧(SCS request frame)，该SCS请求帧用于请求向关联的AP添加一个与应用层相关的低时延业务。服务端向客户端发送确认响应(acknowledgement，ACK)，然后发送一个SCS响应帧(SCS response frame)，该SCS响应帧用于表示收到SCS请求帧，并指示添加低时延业务成功或失败。
其中，如图26所示，为SCS请求帧的格式示意图，该SCS请求帧包括以下字段：
类别(category)，用于指示该请求帧所属的类别；
强健行动(robust action)，用于指示该类别中的哪个帧；
对话令牌(dialog token)；

其中，如图27所示，为一个SCS描述符的格式示意图，该SCS描述符包括以下字段或元素：
元素标识符(element ID)；
长度(length)；
流分类服务标识符(stream classification service identifier，SCSID)，包括1个字节，用于指示对该SCS流所分配的标识符。为了复用现有协议中的发送流(transmit stream)/类别请求/报告(category request/report)，EHT STA或者non-AP MLD在分配SCSID时，将如图17所示的TID字段中的B0位始终置为1，用于指示该字段中包括的是SCSID(占用B0～B7位)；如果TID字段中的B0位置为0，则用于指示该字段中的B3～B7位包括的是TID。从而，通过复用TID字段实现了不同的指示；
请求类型(request type)，包括1个字节，用于指示请求的类型，可以是请求添加(add)，请求移除(remove)和请求更改(change)中的任一个；

状态码(status code)，用于指示所请求的SCS ID是否被接受。
然而，对于多链路场景，AP在添加上述低时延业务后，可以由多条链路承载上述低时延业务，但并没有相关方案可以使得AP可以获得STA的承载该低时延业务的各条链路的业务质量。
有鉴于此，本申请实施例提供又一种业务指示方法，该方法的流程与图7相同。其中，业务质量测量报告的内容也与图7所示实施例基本相同，所不同的是，在图7所示实施例中，业务质量测量报告包括通信标识符比特位图，而在本实施例中，业务质量测量报告包括SCS ID，AP根据接收到的业务质量测量报告中携带的该SCS ID，可以获取该SCS ID对应的低时延业务在每条链路上的业务质量。具体的业务质量测量报告的格式如图29和图30所示。
根据本申请实施例提供的又一种业务指示方法，多链路发送端设备通过在业务质量测量报告中包括链路指示信息和链路的业务质量信息，该链路指示信息用于指示承载低时延业务的多条链路，该链路的业务质量信息包括承载低时延业务的多条链路中每条链路上丢失的媒体接入控制服务数据单元的数量，从而使得对端可以根据业务质量测量报告准确地确定多链路中每条链路的业务质量，提高了业务传输的可靠性。
所属领域的技术人员可以清楚地了解到，为描述的方便和简洁，上述描述的系统、装置和单元的具体工作过程，可以参考前述方法实施例中的对应过程，在此不再赘述。
在本申请所提供的几个实施例中，应该理解到，所揭露的系统、装置和方法，可以通过其它的方式实现。例如，该单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如，多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以 忽略，或不执行。所显示或讨论的相互之间的耦合、或直接耦合、或通信连接可以是通过一些接口，装置或单元的间接耦合或通信连接，可以是电性，机械或其它的形式。
作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部单元来实现本实施例方案的目的。
