这里，可以由Wi-Fi通信系统中的接入点(AP，Access Point)或者站点(STA，Station)发送第一类数据帧。
第一类数据帧可以包括但不限于多连接通信中的数据帧。例如，第一类数据帧可以是符合下一代Wi-Fi网络中IEEE802.11be标准下的数据帧。相对于第一类数据帧，第二类数据帧可以是相关技术中适用于单连接传输的数据帧。例如，第一类数据帧可以是符合IEEE802.11ax标准下的数据帧。数据帧可以是：媒体访问控制服务数据单元(MSDU，Media Access Control Service Data Unit)、聚合媒体访问控制服务数据单元(A-MSDU， Aggregation-Media Access Control Service Data Unit)、或媒介访问控制管理协议数据单元(MMPDU Media Access Control Management Protocol Data Unit)。
第一序列控制域用于唯一标识数据帧，在AP或STA进行满足QoS的传输时用于过滤重复的数据帧。
第一序列控制域可以包含有QMF序列号域、ACI域和片段号域等。针对在多传输通信中传输速度块、传输数据量大的特点，可以基于多传输通信中需要标识的数据包片段、以及需要标识的第一类数据帧的数量等确定第一比特长度。可以通过改变第一类数据帧中第一序列控制域的第一比特长度，使第一序列控制域可以支持多连接通信。这里，第一序列控制域可以支持多连接通信可以指第一序列控制域既能够用于进行单连接通信，也能够用于进行多连接通信。
这里，为满足多连接传输的需求，第一比特长度的第一序列控制域能表征的不同标识信息的数量可以大于或等于至少两个连接传输的数据帧的数量。其中，第一序列控制域中QMF序列号域的比特长度能表征的不同QMF序列号的数量可以大于或等于至少两个连接传输的数据帧的数量、和/或第一序列控制域中片段号域的比特长度能表征的不同片段号的数量可以大于或等于至少两个连接传输的数据帧所属不同片段的数量。如此，第一序列控制域可以满足至少两个连接同时传输的数据帧的数量需求。
示例性的，相关技术的第二序列控制域的QMF序列号域的比特长度为10，可以表征1024个数据帧的QMF序列号，1024个QMF序列号可以标识在一个连接上传输的数据帧，满足一个连接上数据帧传输需求。第一序列控制域的QMF序列号域的比特长度可以设置为11，使得第一序列控制域的QMF序列号域可以表征2048个数据帧的QMF序列号，2048个QMF序列号可以标识两个连接同时传输的数据帧，满足两个连接上数据帧传输需 求。
如此，可以通过设置第一比特长度，使得第一序列控制域可以标识更多的数据帧等，从而使第一序列控制域可以满足多连接通信的需求，进而AP和STA可以采用多连接进行基于QOS的数据帧传输，提高传输速度，提高网络数据吞吐量。
在一个实施例中，所述第一序列控制域包括第一序列号域，所述第一序列号域至少包括指示所述第一类数据帧的序列号的第一QMF序列号域。
这里，如图1所示，第一序列控制域包括第一序列号域。如图2所示，第一序列号域包括第一QMF序列号域。第一QMF序列号域用于设置第一数据帧的序列号。第一数据帧的序列号可以唯一标识第一数据帧。
第一QMF序列号域的比特长度可以基于多传输通信中可能的最大第一类数据帧数量确定。
在一个实施例中，所述第一序列控制域包含有第一片段号域，所述第一片段号域指示所述第一类数据帧的片段号。
这里，第一片段号域用于设置第一数据帧的片段号。第一数据帧的序列号可以唯一标识第一数据帧所属片段。
通常一个数据包在传输时会被分成多个片段，片段号域用于指示数据帧所属的片段。
第一片段号域的比特长度可以基于多传输通信中可能的片段数量确定。
在一个实施例中，所述第一序列控制域的比特长度为固定值。
第一序列控制域的比特长度可以采用固定值，即第一序列控制域的比特长度不随传输连接数量等传输环境的变化而变化。
第一序列控制域中序列号域的比特长度、片段号域的比特长度，以及序列号域中QMF序列号域的比特长度等均可以采用固定值。
示例性的，第一序列控制域可以是18位，其中，QMF序列号域相对相关技术增加两位，为14位。如此，QMF序列号域可设置的QMF序列号数量为原来的4倍。
第一序列控制域的比特长度采用固定值，可以降低动态调节第一序列控制域的比特长度的复杂程度，降低开发难度。
在一个实施例中，其中，所述第一序列控制域的比特长度大于第二类数据帧中的第二序列控制域的比特长度，其中，所述第一类数据帧的类型不同于所述第二类数据帧，并且所述第二序列控制域的比特长度被配置为仅用于支持单连接通信。
第二序列控制域可以是IEEE802.11ax标准下第二类数据帧的序列控制域。第二序列控制域的比特长度可以是16。
在多连接通信下，AP和STA之间会建立多个传输连接。例如，一个AP连接3个STA，每个STA和AP建立3个传输连接，如此，AP同时和3个STA建立有9个传输连接。9个传输连接传输的数据量大大增加，即数据帧数量大大增加。如此，序列控制域中的QMF序列号域能支持的QMF序列号数量，和/或片段号域支持的片段号数量，不能满足唯一标识每个数据帧的需求。
因此，可以将第一类数据帧中第一序列控制域的比特长度，大于第二类数据帧中第二序列控制域的比特长度，使得第一类数据帧中第一序列控制域可以支持的QMF序列号数量，和/或片段号数量能满足多连接通信的数据帧数量的需求。
示例性的，可以使第一类数据帧中第一序列控制域的比特长度相比第二类数据帧中第二序列控制域的比特长度增加两位，即第一序列控制域为18位。增加的比特长度可以用于QMF序列号域，和/或片段号域。例如，QMF序列号域增加一个比特位，可以是QMF序列号域可设置的QMF序列 号数量增加一倍，如此，可以满足更多数据帧的传输需求。
如此，相对第二类数据帧中第二序列控制域，增加第一类数据帧中第一序列控制域的比特长度，可以增加第一序列控制域可以标识数据帧的数量，使得第一序列控制域可以满足多连接通信的需求，进而AP和STA可以采用多连接进行数据帧传输，提高传输速度，提高网络数据吞吐量及提高频谱利用率。
在一个实施例中，所述第一序列控制域中的所述第一序列号域的比特长度大于所述第二序列控制域中的第二序列号域的比特长度，
和/或，
所述第一序列号域中的第一QMF序列号域的比特长度大于所述第二序列号域中的第二QMF序列号域的比特长度。
这里，可以相对第二序列号域增加第一序列号域的比特长度，可以增加第一序列控制域中的序列号域的第一QMF序列号域,和/或增加中第一序列控制域的序列号域的访问类型索引域比特长度。
增加第一序列控制域的序列号域中QMF序列号域的比特长度，如此，可以增加第一序列控制域可以支持的QMF序列号数量，满足多连接通信下，数据帧数量增加的需求。
增加第一序列控制域的序列号域中访问类型索引域的比特长度，如此，可以增加访问类型索引域能指示的数据类型，满足更多类型数据传输的需求。
在一个实施例中，所述第一序列控制域中的所述第一序列号域的比特长度大于12。
针对相关技术中的第二类数据帧中第二序列控制域的比特长度为12，可以设置第一序列控制域中的第一序列号域的比特长度大于12。例如，可以设置第一序列控制域中的第一序列号域的比特长度为16。
这里，新增加的4个比特位，可以都分配给第一序列控制域的第一QMF序列号域和/或访问类型索引域。
在一个实施例中，所述第一序列控制域的所述第一序列号域的第一所述QMF序列号域的比特长度大于10。
相关技术中的第二类数据帧中第二序列控制域的QMF序列号域的比特长度为10，可以设置第一序列控制域中的序列号域的第一QMF序列号域的比特长度大于10
示例性的，可以设置第一序列控制域中的第一序列号域的第一QMF序列号域的比特长度为14比特位。增加后4比特位后，QMF序列号域可以指示的数据帧的数量是相关技术的16倍，进而可以增加多连接可传输的数据帧的数量，提高网络数据吞吐量。
在一个实施例中，所述第一序列控制域中的第一片段号域的比特长度大于所述第二序列控制域中的第二片段号域的比特长度。
增加第一序列控制域的第一片段号域的比特长度，可以增加第一片段号域能指示的片段数，使得多传输连接可以传输更多的数据包的片段，提高网络数据吞吐量。
在一个实施例中，所述第一序列控制域中的所述第一片段号域的比特长度大于4。
相关技术中的第二类数据帧中第二序列控制域的第一片段号域的比特长度为4，可以设置第一序列控制域中的第一片段号域的比特长度大于4。
示例性的，可以设置第一序列控制域中的第一的片段号域的比特长度为8。增加后4位后，第一片段号域可以指示的数据包分成的片段的数量是相关技术的16倍。如此，可以增加多连接可传输的数据包片段的数量，提高网络数据吞吐量。
在一个实施例中，所述确定针对第一类数据帧的第一序列控制域包括：
基于所述第一设备的连接数量，确定所述第一序列控制域的比特长度。
第一序列控制域的比特长度可以根据AP与STA建立的连接数变化。
例如，当AP与STA建立有1个连接时，第一序列控制域的比特长度为16，其中，第一序列控制域中序列号域的比特长度为12，第一序列控制域中片段号域的比特长度为4个。当AP与STA建立有两个连接时，第一序列控制域的比特长度可以增加1位。第一序列控制域的比特长度为17。增加的比特位可以配置给第一序列控制域中序列号域的QMF序列号域。如此，可以增加QMF序列号域指示的数据帧的数量，进而可以增加多连接可传输的数据帧的数量，提高传输效率。
如此，根据接入点的连接数量，增加第一类数据帧中第一序列控制域的比特长度，可以根据连接数量灵活调整第一序列控制域的比特长度，满足多连接通信的需求，提高第一序列控制域的比特长度配置灵活性，进而实现AP和STA可以采用多连接进行数据帧传输，提高传输速度，提高网络数据吞吐量。
更进一步地，连接是指站点与接入点进行数据传输的通信信道，可以是2.4GHz、5GHz及6-7GHz频段中的至少两个信道或全部，或为任意频段中不同的带宽形成的连接。
在一个实施例中，所述基于第一设备的连接数量，确定所述第一序列控制域占用的比特长度，包括：
基于所述第一设备的连接数量，确定所述第一序列号域的所述第一QMF序列号域的比特长度和/或所述第一序列控制域中的第一片段号域的比特长度。
连接数量越多，可以传输的数据帧的数量越多，数据帧携带的数据包的片段越多。因此，可以基于连接数量的变化，确定所述第一序列控制域中的序列号域的第一QMF序列号域的比特长度和/或所述第一序列控制域 中的第一片段号域的比特长度。
例如，可以在连接数量增加时，增加第一序列控制域的第一序列号域中第一QMF序列号域的比特长度，如此，可以增加第一序列控制域可以支持的QMF序列号数量，满足多连接通信下，数据帧数量增加的需求。
可以在连接数量增加时，增加第一序列控制域的第一片段号域的比特长度，可以增加第一片段号域能指示的片段数，满足多连接通信下，片段数增加的需求，使得多传输连接可以传输更多的数据包，提高传输效率。
在一个实施例中，所述基于所述第一设备的连接数量，确定所述第一序列号域的所述第一QMF序列号域的比特长度，包括：
将所述第一设备的连接数量的二进制值所占比特长度与第一基础值之和，确定为所述第一序列控制域中的所述第一序列号域的第一QMF序列号域的比特长度。
这里，第一基础值可以是相关技术中第二QMF序列号域的比特长度。
相关技术中，第二QMF序列号域为10位。当连接数量加倍时，QMF序列号域可以支持的QMF序列号数量也需要加倍，因此，可以将所述接入点的连接数量的二进制值所占比特长度加10之和，确定为第一QMF序列号域的比特长度。
示例性的，相关技术中，第二QMF序列号域比特长度为10，3个站点与AP建立了初始关联，每个STA与AP分别建立有三个连接，如此，AP在9个连接下通信。9的二进制数是1001，占用4个比特长度，因此，可以设置第一QMF序列号域的比特长度为14个比特位。
在一个实施例中，所述基于所述第一设备的连接数量，确定所述第一序列控制域中的第一片段号域的比特长度包括：
将所述第一设备的连接数量的二进制值所占比特长度与第二基础值之和，确定为所述第一序列控制域中的第一片段号域的比特长度。
这里，第二基础值可以是相关技术中片段号域的比特长度。
相关技术中，第二片段号域为4位。当连接数量加倍时，片段号域可以支持的片段号也需要加倍，因此，可以将所述接入点的连接数量的二进制值所占比特长度加4之和，确定为第一片段号域的比特长度。
示例性的，相关技术中，第二片段号域比特长度为4，3个站点与AP建立了初始关联，每个STA与AP分别建立有三个连接，如此，AP在9个连接下通信。9的二进制数是1001，占用4个比特长度，因此，可以设置第一片段号域的比特长度为8个比特位。
在一个实施例中，所述第一设备的连接数量，包括：所述第一设备当前建立的连接的数量和/或所述第一设备支持的最大连接数量。
这里，接入点可以与一个站点建立多个连接。接入点与一个站点可以同时建立有多个连接，利用多个连接传输数据，提高数据传输速度，提高网络数据吞吐量。
多个连接可以包括多连接通信中建立的每个连接、和/或建立的单连接。
第一设备的连接数量可以是当前接入点和/或站点建立的多个连接，也可以是当前接入点和/或站点可以支持的最大连接数量。基于当前建立的连接的数量和/或支持的最大连接数量确定第一序列控制域的比特长度，可以使第一序列控制域可以满足接入点和/或站点在当前建立的连接下进行通信，和/或在最大连接数量进行通信。
在一个实施例中，所述方法还包括：
根据从第二设备接收的管理帧中携带的指示信息，确定所述第二设备是否支持所述多连接通信。
这里，第二设备可以是无线通信中的STA。
STA与AP建立初始关联的过程中，可以在管理帧中携带站点支持多连接的指示信息。AP可以基于指示信息确定STA是否支持多连接。如果STA 支持多连接，则AP可以与STA建立多个连接进行数据传输。提高数据传输速度，提高网络数据吞吐量。这里，管理帧可以包括信标请求(probe request)、关联请求帧(association request)和重关联请求帧(re-association request)等。AP与STA建立的连接数量可以在数据通信过程中确定。
以下结合上述任意实施例提供一个具体示例：
A、序列控制(sequence control)域的设置；
序列控制域可以采用两种比特长度设置方法：
方法1：固定比特长度的序列控制域：
新定义序列控制域，其长度为24比特位，具体为：
如图1所示，片段号(fragment number)域可为8比特位，序列号(Sequence number)域为16比特位。
其中，如图2所示，序列号域具体可定义为：
其中QMF序列号域设置14比特位，ACI为2比特位。
方法2：根据AP支持的连接数量设置序列控制域的比特长度：
可定义新的信息元素(IE，Information Element)来确定序列号域，AP可以分配现有比特长度序列号域为除IEEE802.11be之外的STA使用。AP可以根据与其关联所有STA的通信连接来确定序列号域及片段号域的长度。譬如：3个站点与AP建立了初始关联，且其能在9个连接下去通信，其定义的QMF序列号域比特长度为14比特位，片段号域的比特长度定义为8比特位。
B：同时多连接通信能力信息通知
STA与AP建立初始关联的过程中，譬如在信标请求(probe request)帧、关联请求(association request)帧、重关联请求(re-association request)帧等管理帧中携带其支持多连接的能力信息值。具体的通信连接数量在AP和STA数据通信过程中可以确定下来。通信连接数量可以作为上述方法2 中的依据。
