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。
包括一个或多个AP的多链路设备或称AP MLD,包括一个或多个non-AP STA的多链路设备或称Non-AP MLD,在申请实施例中,Non-AP MLD可以称为STA MLD。
在本申请实施例中,AP MLD可以包括多个AP,Non-AP MLD包括多个STA,AP MLD中的AP和Non-AP MLD中的STA之间可以形成多条链路,AP MLD中的AP和Non-AP MLD中的对应STA之间可以通过对应的链路进行数据通信。
为便于理解本申请实施例的技术方案,以下对本申请相关多AP协作集合建立进行说明。
多AP协作集合的建立分为以下两个阶段:多AP协作能力发现阶段和多AP协作集合建立阶段。
在多AP协作能力发现阶段,AP可以通过接收邻居AP发送的信标(Beacon)帧或其它管理帧来发现彼此的多AP协作能力,如图2所示。
在多AP协作集合建立阶段,如图3所示,发起多AP协作的AP称为主AP(Master AP,MAP),MAP选择其周围的辅AP(Slave AP,SAP)(一个或多个SAP)来参加多AP协作。在这个过程中, MAP和SAP之间会交互一些用于配置多AP协作集合的信息,具体步骤和交互的信息如下:
1)MAP向SAPs发送请求(Request)帧,主要包括以下信息:分配SAP在多AP协作时的标识(identity,ID),分配多AP集合的ID;
2)SAP向MAP回复响应(Response)帧,主要包括以下信息:SAP所关联的STA的信息,包括STA的ID以及参与多AP协作的能力信息;STA参与多AP协作的优先级。
为便于理解本申请实施例的技术方案,以下对本申请相关STA主动/被动探测基本服务集(Basic Service Set,BSS)的方法进行说明。
主动探测(Active Scanning),如图4所示,STA发送探测请求(Probe Request)帧添加服务集标识符(Service Set Identifier,SSID)元素(element)/SSID列表元素主动发现/探测相关的SSID对应的BSS,其中SSID元素和SSID列表元素的格式分别如图5和图6所示。
由于SSID列表元素的SSID列表字段可以添加1个或多个SSID,那么当Probe Request帧中添加的是SSID列表元素时,STA可以请求1个或多个SSID。
值得注意的是,如果SSID字段长度为不为0(Length of SSID field=non-zero),代表请求的是1个具体的SSID;如果SSID字段长度为0(Length of SSID field=0),代表STA请求的是所有的(wildcard)SSID,即STA请求AP返回所有支持的SSIDs(包括隐藏的SSIDs)。
被动探测(Passive Scanning),AP在其发送的Beacon帧或者其它管理帧中添加1个或多个SSID元素,主动广播其所支持的SSID,STA收到Beacon帧通过SSID元素便可发现相关SSID对应的BSS,如图7所示。
为便于理解本申请实施例的技术方案,以下对本申请相关STA关联BSS的方法进行说明。
STA发送关联请求(Association Request)帧给AP,其中STA想要关联的SSID通过SSID元素携带。AP通过关联响应(Association Response)帧将STA的关联结果发送给STA,如果Association Response帧中的状态码(Status Code)指示成功(SUCCESS)时代表STA关联成功,AP会给STA分配1个关联标识(Association ID)(如关联标识符(Association Identifier,AID)),如图8所示。
为便于理解本申请实施例的技术方案,以下对本申请相关STA关联虚拟BSS(Virtual BSS,VBSS)的方法进行说明。
STA关联到VBSS的两种方法:
方法1:基于VBSS协作者的临时密钥生成(Temporal key generation with VBSS Coordinator),具体的,STA与协作者(Coordinator)之间生成成对的主密钥(Pairwise Master Key,PMK)(组主密钥(Group Master Key,GMK))及成对的临时密钥(Pairwise Transient Key,PTK)(组临时密钥(Group Temporal Key,GTK)),Coordinator承担帧的加密和解密任务,其余AP的帧中继到Coordinator处理。
方法2:基于单个AP的临时密钥生成(Temporal key generation with individual APs),具体的,STA与Coordinator之间生成PMK(GMK)及PTK(GTK),其余AP从Coordinator的PMK(GMK)推导得到AP的PMK(GMK),最后STA与其它AP之间生成PTK(GTK),那么STA可以与各个AP直接进行通信。
为便于理解本申请实施例的技术方案,以下对本申请所解决的技术问题进行说明。
1)在上述多AP协作集合建立的方案中,虽然设计了多AP能力发现的基本流程和相关的多AP协作集合建立所需参数,但是并未明确多AP能力信息,没有考虑AP所需要指示的各项多AP能力信息。此外,建立多AP协作集合需要对集合进行分配的参数也不够细致。
2)在上述STA主动/被动探测BSS的方案中,只涉及STA通过SSID element/SSID List element发现传统的BSS,没有涉及STA如何发现多AP协作集合(VBSS);此外,当STA通过wildcard SSID请求获得所有SSID时,也不支持STA按需请求所有的传统SSIDs和VBSS的SSIDs。
3)在上述STA关联BSS的方案中,只支持STA关联到传统的BSS,并不涉及STA发现多AP集合之后请求关联到多AP协作集合的操作。
4)在上述STA关联VBSS的方案中,虽然设计了两种STA关联到VBSS(多AP协作集合)的方法,但没有针对不同的网络架构细化设计STA关联到VBSS的流程和帧结构等,此外也没有明确Coordinator与其它AP之间交互的信息具体有哪些。
基于上述问题,本申请提出了一种多AP协作的方案,设计了STA发现多AP协作集合及所使用的帧结构,以及STA关联多AP协作集合及所使用的帧结构,从而可以实现多AP协作传输。
需要说明的是,在本申请实施例中,多AP协作集合(Multi-AP Candidate Set)和虚拟基本服务集(VBSS)的概念是一致的,文中有时会混用两个名词,但表示的都是同样的概念。
在一些实施例中,本申请可以应用于如图9所示的有线多AP协作架构,也可以应用于如图10 所示的无线多AP协作架构。
具体的,在有线多AP协作架构中,如图9中的(a)所示,网络中的协作者(Coordinator)处于某个AP中,通过有线连接控制其它APs;如图9中的(b)所示,网络中存在一个独立的协作者(Coordinator),通过有线连接控制其它APs。对于有线多AP协作架构,多AP协作集合建立由网络运营商在控制者(Controller)处直接设置。例如,控制者(Controller)通过有线连接获取各个AP的多AP协作能力信息,并分配好多AP协作集合(Multi-AP Candidate Set(s))。
具体的,在无线多AP协作架构中,网络中的协作者(Coordinator)处于某个AP中(称作MAP),通过无线方式控制其它APs(称作SAPs)。在多AP协作集合建立前,各个AP需要先了解其它AP的多AP协作能力信息等,然后MAP决定与哪些SAP(s)建立支持哪些多AP协作模式的多AP协作集合(Multi-AP Candidate Set(s))。
以下通过具体实施例详述本申请的技术方案。
图11是根据本申请实施例的无线通信的方法200的示意性流程图,如图11所示,该无线通信的方法200可以包括如下内容中的至少部分内容:

具体的,STA被动发现多AP协作集合的流程可以如图13所示,各个AP(或仅MAP)通过Beacon帧(或其它管理帧)携带“多AP协作集合信息元素(Multi-AP Candidate Set Info element)或多AP协作集合信息字段(Multi-AP Candidate Set Info field)”和/或“SSID element或SSID field”广播其所属的多AP协作集合的信息,STA接收Beacon帧(或其它管理帧)可以获知多AP协作集合的信息。

在一些实施例中,该SSID字段对应的长度字段对应的第一值为非零值,该SSID字段对应的长度字段对应的第二值为零。

在一些实施例中,在该SSID字段对应的长度字段取值为非零的情况下,该STA请求该第一SSID;和/或,在该SSID字段对应的长度字段取值为零的情况下,该STA请求所有的SSID(wildcard SSID) (即STA请求P个SSID)。

S320,该第一AP向该STA发送关联响应帧,其中,该关联响应帧至少包括该STA请求关联的传统的SSID对应的AID信息和/或该STA请求关联的VBSS的SSID对应的VAID信息;
S330,该第一AP向第二AP发送共享信息;其中,该第二AP与该第一AP属于相同的传统的SSID,或者,该第二AP与该第一AP属于相同的VBSS的SSID,该共享信息包括该STA的MAC地址和/或该STA的多AP协作能力信息;
S340,该第一AP接收该第二AP发送的确认信息,该确认信息用于指示该第二AP是否接受该STA的关联请求。
需要说明的是,上述S330和S340为可选步骤,在一些情况下,可以不执行。
在一些实施例中,在该第一AP接收该STA发送的该关联请求帧与该第一AP向该STA发送该关联响应帧之间,该第一AP向该第二AP发送该共享信息。也即,上述S330和S340可以发生在S310与S320之间,或者,至少上述S330可以发生在S310与S320之间。
在一些实施例中,在该第一AP向该STA发送该关联响应帧之后,该第一AP向该第二AP发送该共享信息。也即,上述S330和S340可以发生在S320之后。
在本申请实施例中,一个AP可能属于一个或多个多AP协作集合。
在本申请实施例中,每个多AP协作集合应只有一个MAP,其余AP为SAP。
在本申请实施例中,每个多AP协作集合可能支持一种或多种多AP协作模式。
在本申请实施例中,传统的SSID为一个字符串,该字符串用于指示包括了扩展服务集的基础设施基本服务集(A string used to identify the infrastructure basic service sets(BSSs)that comprise an extended service set(ESS)),或者,该字符串用于指示非基础设施基本服务集(A string used to identify a non-infrastructure BSS)。
在本申请实施例中,VBSS的SSID:一个用于指示多个AP协作集合(或VBSS)的字符串(A string used to identify the Multi-AP Candidate Set(or VBSS))。
在一些实施例中,在该STA关联至该第一AP之后,该STA向该第一AP请求关联至多AP协作集合。也即,STA可以先关联到其周边的1个AP(例如为锚点AP(Anchor AP)或MAP),再向该AP请求关联到相应的多AP协作集合。也即,在本实施例中,该第一AP可以是Anchor AP或MAP。
在一些实施例中,在该STA请求关联至该第一AP同时,该STA向该第一AP请求关联至多AP协作集合。也即,STA向其周边的1个AP(例如为Anchor AP或MAP)请求同时关联到该AP和相应的多AP协作集合。也即,在本实施例中,该第一AP可以是Anchor AP或MAP。
具体例如,STA请求关联多AP协作集合的基本流程可以如图20所示。图20仅以STA直接向拥有协作者(Coordinator)的AP 1请求关联为例,具体可以包括如下步骤:1)STA向AP 1发送关联请求(Association Request)帧请求关联到该AP 1,Association Request帧中新增的SSID元素/SSID列表元素指示STA通过AP 1关联到相应的VBSS;2)STA请求关联的AP 1将STA的(关联)信息分享给STA请求关联的VBSS中的其它APs;3)AP通过关联响应(Association Response)帧给STA,分配关联标识符(Association Identifier,AID)和虚拟关联标识符(Virtual AID,VAID)并告知协作者密钥持有标识(Coordinator key holder ID)以及密钥生成方法(Key generation method)指示等信息。其中,协作者密钥持有标识用于生成PMK(GMK)。
需要说明的是,如果STA所请求关联的AP是协作者(Coordinator),媒体接入控制(Media Access Control,MAC)层成帧在Coordinator做,那么,上述图20中的第2)步Coordinator也可以不分享STA的(关联)信息给VBSS中的其它Aps。如果需要执行上述图20中的第2)步,Coordinator给其它APs分享STA的(关联)信息的操作可以在关联请求(Association Request)帧与关联响应(Association Response)帧之间的某个时刻进行,也可以在Association Response之后的某个时刻进行。
在一些实施例中,在该第一AP为协作者(Coordinator),且MAC层成帧由协作者执行的情况下,该第一AP无需向该STA请求关联的多AP协作集合对应的其他AP分享该STA的相关信息。
在一些实施例中,协作者密钥持有标识用于生成STA与协作者之间的成对的主密钥(Pairwise Master Key,PMK)和/或组主密钥(Group Master Key,GMK)和成对的临时密钥(Pairwise Transient Key,PTK)和/或组临时密钥(Group Temporal Key,GTK)。
在一些实施例中,在该第一AP为协作者(Coordinator),且MAC层成帧由协作者执行的情况下,该第一AP直接建立与该STA之间的PMK和/或GMK和PTK和/或GTK。
在一些实施例中,在该第一AP为协作者(Coordinator),且MAC层成帧由协作者执行的情况下,该第一AP向该STA请求关联的多AP协作集合对应的其他AP发送触发帧;其中,该触发帧中指定的资源和传输模式用于对应的AP向该STA发送该第一AP分享的数据。
在一些实施例中,该关联请求帧的接收地址(Receiving Address,RA)字段用于指示该STA请 求关联的AP的基本服务集标识(Basic Service Set Identifier,BSSID),或者,该关联请求帧的RA字段用于指示该STA请求关联的AP的MAC地址。
在一些实施例中,在该第一AP为协作者的情况下,该第一AP直接将该STA的关联信息分享给该STA请求关联的多AP协作集合对应的其他AP。
在一些实施例中,在该第一AP为非协作者的情况下,该第一AP将该STA的关联信息分享给该STA请求关联的多AP协作集合对应的协作者,然后,该STA请求关联的多AP协作集合对应的协作者将该STA的关联信息分享给该STA请求关联的多AP协作集合对应的其他AP。
在一些实施例中,如图21所示,在AP1(即本申请中的第一AP)为非协作者的情况下,也即,Coordinator位于STA请求关联的多AP协作集合对应的其它AP。Coordinator(AP)与其它APs之间的交互通过无线连接进行,需要设计关联信息共享(Association Info.Share)帧和关联信息确认(Association Info.Confirm(Ack))帧。
