为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
无线设备支持多频段通信，例如，同时在2.4GHz，5GHz，6GHz以及60GHz频段上进行通信，或者同时在同一频段(或不同频段)的不同信道上通信，提高设备之间的通信吞吐量和/或可靠性。这种设备通常称为多频段设备，或称为 多链路设备(Multi-Link Device，MLD)，有时也称为多链路实体或多频段实体。多链路设备可以是接入点设备，也可以是站点设备。如果多链路设备是接入点设备，则多链路设备中包含一个或多个AP；如果多链路设备是站点设备，则多链路设备中包含一个或多个non-AP STA。
为便于理解本申请实施例的技术方案，以下对本申请相关技术方案及存在的问题进行说明。
在介绍本申请技术方案之前，先对本申请涉及的一些技术知识进行介绍说明。
在相关标准协议中，定义了可以支持多链路(Multiple Links)的功能。按照标准协议中对于通信两端的定义，一个是STA MLD，一个是AP MLD。相互建立了多链路的STA MLD和AP MLD可以利用多链路的优势，在多个链路上进行数据收发，以达到高吞吐/低时延等优势。
在传统的单链路设备中，每个单链路设备都有一个MAC地址，这个单链路设备可以用这个单个MAC地址来识别。在相关标准中定义的多链路设备中，因为在多链路设备中会有多个链路，每个链路上都有独立的MAC地址，同时一个多链路设备还有一个单个的多链路设备MAC地址(MLD MAC address)。
图2示出了多链路设备的参考模型。如图2所示，两个多链路设备之间有两个链路(Link)：链路1和链路2，且每个多链路设备在低层MAC(Lower MAC layer)中，在每个链路上都有独立的链路MAC地址(Link MAC address)，或称为无线媒体(Wireless Medium，WM)MAC地址，同时在上层MAC(Upper MAC layer)中有一个单个的MLD MAC地址。
在相关标准协议中，连接到AP MLD中的任一AP的两个STA间，可以建立TDLS链路，在这个TDLS链路上，两个STA间可以直接相互进行数据传输，不需要经过AP。
如图3所示，一个STA MLD包含两个STA:STA1、STA2，一个AP MLD包含两个AP:AP1、AP2，分别工作在链路1和链路2上，同时在AP1上连接有一个传统的STA3。并且，在STA1和STA3间建立了一条TDLS链路。按相关标准协议规定，在STA1和STA3间的TDLS链路上进行交互的包中，所携带的基本服务集标识符(Basic Service Set Identifier，BSSID)和基本服务集颜色(BSS Color)就是AP1的BSSID和BSS Color。
按当前标准协议中的规则，STA1和AP1间的链路上使用各自的链路MAC地址进行相互数据交互；而在STA1和STA3间的TDLS链路上，STA1是属于一个STA MLD，STA1使用其MLD MAC地址与STA3进行相互数据交互。
以图3所示的拓扑为例，STA1在和AP1在链路1上建立了连接，并且又和STA3建立了一个TDLS链路的情况下，当STA1和AP1在链路1上进行包交互时，对应的包的地址填写为如图4所示。比如，此时从AP1到STA1的包，这个包的接收地址(Receiver Address，RA)填写的是STA1的链路MAC地址。
对应的，当STA1和STA3在TDLS链路上进行包交互时，对应的包的地址 填写为如图5所示。比如，此时从STA3到STA1的包，这个包的接收地址填写的是MLD_S，即STA1的MLD MAC地址。
在当前标准协议中，NAV机制是基本信道接入机制。如图6所示，当源(Source)设备和目的(Desination)设备两个设备间进行包交互时，这时有其他(Other)设备，在收到源设备或目的设备的包时，会通过检测这个包的MAC地址等字段，发现不是发给自己的包，根据这个包里的信息，更新自己的NAV，更新后的NAV大于0。当某个设备的NAV不为0时，这个设备是不可以直接接入信道进行发送，同时在收到请求发送(Request to Send，RTS)等帧时，也不可以回复允许发送(Clear to Send，CTS)等对应的响应帧。
针对如图3所示的属于STA MLD中的STA1而言，因为有两个链路，且这两个链路：链路1和TDLS链路是可以工作在相同信道上，这就使得在这个两个链路上，AP1->STA1和STA3->STA1的包都是给STA1的，但在不同链路上的包的目的地址是不同的，一个是STA MLD的MLD MAC地址，一个是STA1的链路MAC地址。
这样如果当STA1将STA1的链路MAC地址当作自己的唯一MAC地址，会使得STA1在收到TDLS链路上的包时，也会将自己的NAV更新，从而出现错误。
为了解决上述问题，本申请实施例提供有如下技术方案。下面，通过几个实施例对本申请技术方案进行介绍说明。
请参考图7，其示出了本申请一个实施例提供的网络分配向量设置方法的流程图。该方法可应用于图1所示的通信系统中，由通信系统中的STA执行。该方法可以包括如下步骤：
步骤702：STA MLD中的第一STA接收数据包。
在本申请实施例中，STA MLD中存在建立有TDLS链路的目标STA，目标STA在TDLS链路上使用STA MLD对应的MLDMAC地址。
TDLS链路是由接入APMLD中的同一AP的两个STA之间建立的链路。在本申请实施例中，STA MLD中包括目标STA，该目标STA和一个单链路STA与APMLD中的同一个AP相连接，因此，目标STA与该单链路STA可以建立TDLS链路。
示例性的，如图3所示，STA1和STA3均与AP1相连接，STA1和STA3之间建立有TDLS链路。
步骤704：在数据包的目的地址为MLD MAC地址，和/或，数据包的目的地址为第一STA对应的链路MAC地址的情况下，第一STA不更新第一STA的NAV。
在本申请实施例中，第一STA对接收到的数据包进行识别，并在识别出数据包是发送给自己的数据包的情况下，不更新自己的NAV。
第一STA通过数据包的目的地址判断是否是发送给自己的数据包，并将MLD MAC地址和链路MAC地址均视为自己的地址，从而在接收到的数据包的目的地址为MLD MAC地址或链路MAC地址的情况下，第一STA可以正确识别出接收到的数据包是发送给自己的包，进而不更新自己的NAV。
在本申请实施例中，第一STA是STA MLD中的任意一个STA。第一STA可以是建立有TDLS链路的目标STA，也可以是目标STA之外的其他STA，其他STA是STA MLD中，除了目标STA之外的STA。
示例性的，结合参考图3，STA1建立有TDLS链路，STA1是目标STA，STA2是其他STA。第一STA包括：STA1和STA2，步骤702和步骤704可以由STA1执行，也可以由STA2执行。
也即，STA MLD中的某个STA，在收到一个数据包时，在如下任一条件满足的情况下，这个STA不会更新其NAV：
条件a)这个数据包的目的地址是这个STA对应的STA MLD的MLD MAC地址。
条件b)这个数据包的目的地址是这个STA对应的链路MAC地址。
示例性的，结合参考图4，STA1从AP1上收到数据包的目的地址A1(RA)是STA1，即STA1的链路MAC地址，则STA1不会根据这个包的信息来更新自己的NAV。
示例性的，结合参考图5，STA1从STA3上收到数据包的目的地址A1(RA)是MLD_S，即STA1的MLD MAC地址，则STA1不会根据这个包的信息来更新自己的NAV。
在本申请一种实施例中，STA MLD对应的MLD MAC地址与第一STA的链路MAC地址是不同的两个地址。在本申请一种实施例中，STA MLD对应的MLD MAC地址与第一STA的链路MAC地址是相同的地址。
综上所述，本实施例提供的技术方案，STA MLD中的目标STA建立了TDLS链路，且目标STA在TDLS链路上使用STA MLD对应的MLD MAC地址，则将STA MLD中的任意一个STA记为第一STA，在第一STA接收到数据包后，若这个数据包的目的地址是这个STA对应的STA MLD的MLD MAC地址或者这个STA对应的链路MAC地址，则该第一STA可以正确地处理该数据包的目的地址，不更新自己的NAV，避免错误地更新自己的NAV的情况，进而完善了STA MLD中的STA的NAV设置机制。
在本申请一种实施例中，STA MLD中的STA将MLD MAC地址视为自己的地址。
请参考图8，其示出了本申请一个实施例提供的网络分配向量设置方法的流程图。该方法可应用于图1所示的通信系统中，由通信系统中的STA执行。该方法可以包括如下步骤：
步骤802：STA MLD中的第一STA接收数据包。
在本申请实施例中，STA MLD中存在建立有TDLS链路的目标STA，目标 STA在TDLS链路上使用STA MLD对应的MLD MAC地址。
步骤804：在数据包的目的地址为MLD MAC地址的情况下，第一STA不更新第一STA的NAV。
在本实施例中，第一STA通过数据包的目的地址判断是否是发送给自己的数据包，并将MLD MAC地址视为自己的地址，从而在接收到的数据包的目的地址为MLD MAC地址的情况下，第一STA可以正确识别出接收到的数据包是通过TDLS链路发送给自己的包，进而不更新自己的NAV。
示例性的，结合参考图5，STA1从STA3上收到数据包的目的地址A1(RA)是MLD_S，即STA1的MLD MAC地址，则STA1不会根据这个包的信息来更新自己的NAV。
综上所述，本实施例提供的技术方案，STA MLD中的目标STA建立了TDLS链路，且目标STA在TDLS链路上使用STA MLD对应的MLD MAC地址，则将STA MLD中的任意一个STA记为第一STA，在第一STA接收到数据包后，若这个数据包的目的地址是这个STA对应的STA MLD的MLD MAC地址，则该第一STA可以正确地处理该数据包的目的地址，不更新自己的NAV，避免错误地更新自己的NAV的情况，进而完善了STA MLD中的STA的NAV设置机制。
在本申请一种实施例中，MLD MAC地址与第一STA对应的链路MAC地址相同。
请参考图9，其示出了本申请一个实施例提供的网络分配向量设置方法的流程图。该方法可应用于图1所示的通信系统中，由通信系统中的STA执行。该方法可以包括如下步骤：
步骤902：STA MLD中的第一STA接收数据包。
在本申请实施例中，STA MLD中存在建立有TDLS链路的目标STA，目标STA在TDLS链路上使用STA MLD对应的MLD MAC地址。
步骤904：在数据包的目的地址为第一MAC地址的情况下，第一STA不更新第一STA的NAV，第一MAC地址等于MLD MAC地址，且等于第一STA的链路MAC地址。
在本实施例中，第一STA通过数据包的目的地址判断是否是发送给自己的数据包，在MLD MAC地址和链路MAC地址相同的情况下，第一STA将这一相同地址视为自己的地址，从而在接收到的数据包的目的地址为上述地址的情况下，第一STA可以正确识别出接收到的数据包是发送给自己的包，进而不更新自己的NAV。
示例性的，结合参考图10，MLD MAC地址和链路MAC地址相同，均为地址X。STA1从STA3上收到数据包的目的地址A1(RA)是地址X，则STA1不会根据这个包的信息来更新自己的NAV；STA1从AP1上收到数据包的目的地址A1(RA)是地址X，则STA1不会根据这个包的信息来更新自己的NAV。
综上所述，本实施例提供的技术方案，STA MLD中的目标STA建立了TDLS 链路，且目标STA在TDLS链路上使用STA MLD对应的MLD MAC地址，则将STA MLD中的任意一个STA记为第一STA，在第一STA接收到数据包后，在MLD MAC地址与第一STA对应的链路MAC地址相同的情况下，若这个数据包的目的地址是上述相同地址，则该第一STA可以正确地处理该数据包的目的地址，不更新自己的NAV，避免错误地更新自己的NAV的情况，进而完善了STA MLD中的STA的NAV设置机制。
在本申请一种实施例中，目标STA的TDLS链路的工作信道与其他STA所在链路的工作信道不同；其中，其他STA是STA MLD中，除了目标STA之外的STA。
请参考图11，其示出了本申请一个实施例提供的网络分配向量设置方法的流程图。该方法可应用于图1所示的通信系统中，由通信系统中的STA执行。该方法可以包括如下步骤：
步骤1102：STA MLD中的目标STA与对端设备协商TDLS链路的工作信道时，选择与其他STA所在链路的工作信道不同的工作信道；其中，其他STA是STA MLD中，除了目标STA之外的STA。
也即，对于STA MLD中的某个STA，在其建立了一个TDLS链路时，当这个STA与其TDLS链路的对端设备协商这个TDLS链路的工作信道时，这个STA不可以选择STA MLD中的其他STA所在链路的工作信道。
步骤1104：STA MLD中的第一STA接收数据包。
在本申请实施例中，STA MLD中存在建立有TDLS链路的目标STA，目标STA在TDLS链路上使用STA MLD对应的MLD MAC地址。
步骤1106：在数据包的目的地址为MLD MAC地址的情况下，第一STA不更新第一STA的NAV。
在本实施例中，第一STA通过数据包的目的地址判断是否是发送给自己的数据包，并将MLD MAC地址视为自己的地址，从而在接收到的数据包的目的地址为MLD MAC地址的情况下，第一STA可以正确识别出接收到的数据包是通过TDLS链路发送给自己的包，进而不更新自己的NAV。
应理解，通过进行如下设置：目标STA的TDLS链路的工作信道与其他STA所在链路的工作信道不同，可以避免STA MLD中除目标STA之外的其他STA也接收到TDLS链路上的数据包，进而避免在其他STA接收到上述数据包时，基于如步骤1106所示的是否更新NAV的判断机制，错误地根据MLD MAC地址，认为接收到了自己的数据包，进而错误地不更新自己的NAV。
示例性的，结合参考图12，目标STA为STA1，当STA1和STA3之间的TDLS链路通过信道协商，将这个TDLS链路的工作信道协商到STA2所在的链路2的工作信道上时，由于STA2所在的链路2的工作信道和这时STA1和STA3之间的TDLS链路的工作信道相同，STA2也会收到STA3向STA1发送的数据包。
示例性的，结合参考图13，第一STA为STA2，对于STA2而言，STA3向 STA1发送的数据包的目的地址是STA MLD的MLD MAC地址，STA2根据该目的地址，会错误地认为该数据包就是自己的数据包，使得STA2错误地不更新自己的NAV。
因此，通过限制STA1在与STA3协商其TDLS链路的工作信道的选择范围，可以使得STA1和STA3之间的TDLS链路的工作信道不会与STA2所在链路2的工作信道相同，从而避免出现如上情况。
综上所述，本实施例提供的技术方案，在进行信道协商时，将目标STA的TDLS链路的工作信道设置为与其他STA所在链路的工作信道不同，可以避免STA MLD中除目标STA之外的其他STA接收到TDLS链路上的数据包，进而避免其他STA将接收到的TDLS链路上的数据包错误地认为是自己的数据包，错误地不更新自己的NAV。
在本申请一种实施例中，目标STA的TDLS链路的工作信道与其他STA所在链路的工作信道不同；其中，其他STA是STA MLD中，除了目标STA之外的STA。
请参考图14，其示出了本申请一个实施例提供的网络分配向量设置方法的流程图。该方法可应用于图1所示的通信系统中，由通信系统中的STA执行。该方法可以包括如下步骤：
步骤1402：STA MLD中的目标STA与对端设备协商TDLS链路的工作信道时，选择与其他STA所在链路的工作信道不同的工作信道；其中，其他STA是STA MLD中，除了目标STA之外的STA。
也即，对于STA MLD中的某个STA，在其建立了一个TDLS链路时，当这个STA与其TDLS链路的对端设备协商这个TDLS链路的工作信道时，这个STA不可以选择STA MLD中的其他STA所在链路的工作信道。
步骤1404：STA MLD中的第一STA接收数据包。
在本申请实施例中，STA MLD中存在建立有TDLS链路的目标STA，目标STA在TDLS链路上使用STA MLD对应的MLD MAC地址。
步骤1406：在数据包的目的地址为第一STA对应的链路MAC地址的情况下，第一STA不更新第一STA的NAV。
在本实施例中，第一STA通过数据包的目的地址判断是否是发送给自己的数据包，并将链路MAC地址视为自己的地址，从而在接收到的数据包的目的地址为链路MAC地址的情况下，第一STA可以正确识别出接收到的数据包是第一STA与AP之间的链路发送给自己的包，进而不更新自己的NAV。
应理解，通过进行如下设置：目标STA的TDLS链路的工作信道与其他STA所在链路的工作信道不同，可以避免STA MLD中除目标STA之外的其他STA也接收到TDLS链路上的数据包，其他STA在接收到数据包时，基于如步骤1406所示的是否更新NAV的判断机制，可以根据链路MAC地址，认为接收到了自己的数据包，进而不更新自己的NAV。
示例性的，结合参考图3，STA1和STA3之间的TDLS链路通过信道协商， 将这个TDLS链路的工作信道协商到与STA2所在的链路2的工作信道不同的工作信道上。由于STA2所在的链路2的工作信道和这时STA1和STA3之间的TDLS链路的工作信道不同，STA2不会收到STA3向STA1发送的数据包，只会收到AP2向STA2发送的数据包，数据包的目的地址是STA2的链路MAC地址，则STA2不会根据这个包的信息来更新自己的NAV。
综上所述，本实施例提供的技术方案，在进行信道协商时，将目标STA的TDLS链路的工作信道设置为与其他STA所在链路的工作信道不同，可以避免STA MLD中除目标STA之外的其他STA接收到TDLS链路上的数据包，在第一STA接收到数据包后，若这个数据包的目的地址是这个STA对应的链路MAC地址，则该第一STA可以正确地处理该数据包的目的地址，不更新自己的NAV，完善了STA MLD中的STA的NAV设置机制。
在本申请一种实施例中，MLD MAC地址与第一STA对应的链路MAC地址相同。此外，目标STA的TDLS链路的工作信道与其他STA所在链路的工作信道不同；其中，其他STA是STA MLD中，除了目标STA之外的STA。
请参考图15，其示出了本申请一个实施例提供的网络分配向量设置方法的流程图。该方法可应用于图1所示的通信系统中，由通信系统中的STA执行。该方法可以包括如下步骤：
步骤1502：STA MLD中的目标STA与对端设备协商TDLS链路的工作信道时，选择与其他STA所在链路的工作信道不同的工作信道；其中，其他STA是STA MLD中，除了目标STA之外的STA。
也即，对于STA MLD中的某个STA，在其建立了一个TDLS链路时，当这个STA与其TDLS链路的对端设备协商这个TDLS链路的工作信道时，这个STA不可以选择STA MLD中的其他STA所在链路的工作信道。
步骤1504：STA MLD中的第一STA接收数据包。
在本申请实施例中，STA MLD中存在建立有TDLS链路的目标STA，目标STA在TDLS链路上使用STA MLD对应的MLD MAC地址。
步骤1506：在数据包的目的地址为第一MAC地址的情况下，第一STA不更新第一STA的NAV，第一MAC地址等于MLD MAC地址，且等于第一STA的链路MAC地址。
在本实施例中，第一STA通过数据包的目的地址判断是否是发送给自己的数据包，在MLD MAC地址和链路MAC地址相同的情况下，第一STA将这一相同地址视为自己的地址，从而在接收到的数据包的目的地址为上述地址的情况下，第一STA可以正确识别出接收到的数据包是发送给自己的包，进而不更新自己的NAV。
应理解，通过进行如下设置：目标STA的TDLS链路的工作信道与其他STA所在链路的工作信道不同，可以避免STA MLD中除目标STA之外的其他STA也接收到TDLS链路上的数据包，进而避免在其他STA接收到上述数据包时，基于如步骤1506所示的是否更新NAV的判断机制，错误地根据第一MAC地址， 认为接收到了自己的数据包，进而错误地不更新自己的NAV。
示例性的，结合参考图16，MLD MAC地址和STA2的链路MAC地址相同，均为地址X。当STA1和STA3之间的TDLS链路通过信道协商，将这个TDLS链路的工作信道协商到STA2所在的链路2的工作信道上时，由于STA2所在的链路2的工作信道和这时STA1和STA3之间的TDLS链路的工作信道相同，STA2也会收到STA3向STA1发送的数据包。对于STA2而言，STA3向STA1发送的数据包的目的地址是STA MLD的MLD MAC地址，即地址X，STA2根据该目的地址，会错误地认为该数据包就是自己的数据包，使得STA2错误地不更新自己的NAV。
因此，通过限制STA1在与STA3协商其TDLS链路的工作信道的选择范围，可以使得STA1和STA3之间的TDLS链路的工作信道不会与STA2所在链路2的工作信道相同，从而避免出现如上情况。
综上所述，本实施例提供的技术方案，在进行信道协商时，将目标STA的TDLS链路的工作信道设置为与其他STA所在链路的工作信道不同，可以避免STA MLD中除目标STA之外的其他STA接收到TDLS链路上的数据包，进而避免其他STA将接收到的TDLS链路上的数据包错误地认为是自己的数据包，错误地不更新自己的NAV。
在本申请一种实施例中，在数据包的目的地址是MLD MAC地址的情况下，除了对数据包的目的地址进行校验之外，第一STA还需要对数据包的源地址进行校验，进而确定是否更新NAV。
请参考图17，其示出了本申请一个实施例提供的网络分配向量设置方法的流程图。该方法可应用于图1所示的通信系统中，由通信系统中的STA执行。该方法可以包括如下步骤：
步骤1702：STA MLD中的第一STA接收数据包。
在本申请实施例中，STA MLD中存在建立有TDLS链路的目标STA，目标STA在TDLS链路上使用STA MLD对应的MLD MAC地址。
步骤1704：在数据包的目的地址为MLD MAC地址，数据包的源地址来自于与第一STA建立有TDLS链路的对端设备的情况下，和/或，在数据包的目的地址为第一STA对应的链路MAC地址的情况下，第一STA不更新第一STA的NAV。
也即，STA MLD中的某个STA，在收到一个数据包时，在如下任一条件满足的情况下，这个STA不会更新其NAV：
条件a)这个数据包的目的地址是这个STA对应的STA MLD的MLD MAC地址，且这个数据包是来自于这个STA的TDLS链路的对端设备。
条件b)这个数据包的目的地址是这个STA对应的链路MAC地址。
应理解，通过进行如下设置：在数据包的目的地址是MLD MAC地址的情况下，除了对数据包的目的地址进行校验之外，第一STA还需要对数据包的源地址进行校验，进而确定是否更新NAV，可以避免在STA MLD中除目标STA 之外的其他STA也接收到TDLS链路上的数据包时，基于如步骤1704所示的是否更新NAV的判断机制，错误地根据MLD MAC地址，认为接收到了自己的数据包，进而错误地不更新自己的NAV。
示例性的，结合参考图12，目标STA为STA1，当STA1和STA3之间的TDLS链路通过信道协商，将这个TDLS链路的工作信道协商到STA2所在的链路2的工作信道上时，由于STA2所在的链路2的工作信道和这时STA1和STA3之间的TDLS链路的工作信道相同，STA2也会收到STA3向STA1发送的数据包。
示例性的，结合参考图13，第一STA为STA1，对于STA1而言，由于这个数据包的目的地址是STA MLD的MLD MAC地址，且这个数据包的源地址A2(TA)显示这个数据包是来自于STA3，所以STA1不会根据这个包的信息来更新自己的NAV。
示例性的，结合参考图13，第一STA为STA2，对于STA2而言，虽然这个数据包的目的地址是STA MLD的MLD MAC地址，但这个包的源地址A2(TA)显示这个数据包不是来自于STA2的TDLS链路的对端设备，所以STA2仍然会根据这个包的信息来更新自己的NAV。
因此，通过对数据包的源地址进行进一步校验，可以避免在STA1和STA3之间的TDLS链路的工作信道与STA2所在链路2的工作信道相同的情况下，STA2认为接收到的STA3向STA1发送的数据包是发送给自己的数据包，使得STA2错误地不更新自己的NAV。
综上所述，本实施例提供的技术方案，STA MLD中的某个STA，在收到一个数据包时，在数据包的目的地址是MLD MAC地址的情况下，除了对数据包的目的地址进行校验之外，还需要对数据包的源地址进行校验，从而确定是否更新NAV，以避免在与其他链路使用同一工作信道的情况下，错误地将别的链路的数据包认为是自己的数据包，进而不更新自己的NAV。
