具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明实施 例相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本发明实施例的一些方面相一致的装置和方法的例子。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式,除非上下文清楚地表示其他含义。还应当理解,本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解,尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息,但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如,在不脱离本公开实施例范围的情况下,第一信息也可以被称为第二信息,类似地,第二信息也可以被称为第一信息。取决于语境,如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
本公开实施例涉及的执行主体包括但不限于:无线通信网络尤其是Wi-Fi网络如IEEE802.11a/b/g/n/ac标准下,以及下一代Wi-Fi网络如IEEE802.11be标准下的通信设备,其中,通信设备包括但不限于:Wi-Fi路由器等无线(AP,Access Point)接入点设备、无线站点(STA,Station)、用户终端、用户节点、移动终端或平板电脑等。
本公开实施例的一种应用场景为,相关技术中AP支持的最大工作带宽为320MHz,而STA支持的最大带宽小于320MHz,例如:STA支持的最大工作带宽为80MHz或160MHz等。
AP和STA带宽不对称会带来频谱的利用不充分,在IEEE802.11be中可以支持多连接通信,图1a为下行链路,图1b为上行链路,如图1a和1b所示:AP的320MHz带宽被分为两个通道,每个通道的带宽为160MHz。如果AP支持最大的工作带宽为320MHz,而STA支持的最大工作带宽为 160MHz,则在同一时刻AP只能与一个站点在160MHz的最大带宽下进行通信,而另外160MHz的工作带宽不能够被利用。并且会产生两个通道负载不均衡的问题。
如图2所示,本示例性实施例提供一种于通信连接配置方法,可以应用于无线通信的第一通信设备中,该方法包括:
步骤101:接收第一消息帧,其中,第一消息帧包含:指示第二通信设备的工作带宽的第一信息元素。
第一通信设备可以是Wi-Fi无线通信中的无线接入点(AP,Access Point),第二通信设备可以是Wi-Fi无线通信中的无线站点(STA,Station)。
第一消息帧可以是Wi-Fi通信技术中由第二无线通信设备发送的管理帧。第二通信设备可以在与第一通信设备进行关联或重关联过程中发送包含第一信息元素的第一消息帧。其中,第二通信设备可以在与第一通信设备链路验证后进行关联,以便获得网络的访问权。关联属于一种记录保持过程,可以使第一通信设备能够记录第二通信设备,以便将传送给第二通信设备的帧送给正确的第二通信设备。重关联过程是指第二通信设备与第一通信设备脱离关联关系后,再次进行关联的过程。
示例性的,第一消息帧还可以第二无线通信设备发送的数据帧。
示例性的,第二无线通信设备发送的管理帧可以包括:探测请求(Probe Request)帧、关联请求(Association Request)帧或认证请求帧(Authentication Request)帧等。
第二通信设备可以在消息帧中携带第一信息元素,用于指示无线站点的工作带宽。其中,工作带宽可以是第二通信设备当前的工作带宽和无线站点可以支持的最大工作带宽等。
可以在第二通信设备的管理帧的帧主体的预设次序位置设置第一信息元素。示例性的,如图3a所示,可以在探测请求帧次序(order)20的位置 设置第一信息元素。如图3b所示,可以在关联请求帧次序24的位置设置第一信息元素。如图3c所示,可以在认证请求帧次序18的位置设置第一信息元素。
如此,第二通信设备通过消息帧中的第一信息元素指示第二通信设备的工作带宽,提供了一种工作带宽的显性指示方式,第一通信设备可以直接根据包含消息帧中的第一信息元素确定第二通信设备的工作带宽,不需要额外指令对第二通信设备的工作带宽进行查询,提高消息帧包含的信息量,提升获取第二通信设备的工作带宽的便捷程度。
在一个实施例中,接收第一消息帧,包括:通过与第二通信设备之间的第一连接接收第一消息帧;
如图4所示,该通信连接配置方法还可以包括步骤102:基于第二通信设备的工作带宽及第一通信设备支持的最大工作带宽建立N个基本服务集BSS,第一连接配置在N个BSS中的第一BSS上;其中,N为正整数。
第一连接是第一通信设备和第二通信设备之前当前的Wi-Fi连接。BSS基本服务集是Wi-Fi通信网络的基本组件,用于描述在Wi-Fi网络中的一组相互通信的通信设备。
可以在第一通信设备支持的最大工作带宽范围内设置N个BSS。每个BSS的带宽可以根据第二通信设备的工作带宽设置,使得每个BSS可以都可以满足第一通信设备和第二通信设备之前的连接的需求。
示例性的,可以以第二通信设备的当前工作带宽作为每个BSS的带宽。如此,可以将第一连接配置到BSS中。
在一个实施例中,方法还包括:当第一BSS的负载量达到预设阈值时,将第一连接迁移至N个BSS中的第二BSS上;其中,第二BSS不同于第一BSS。
这里,第一BSS的负载量可以包括:第一BSS承载的无线站点等通信 设备的数量、和/或第一BSS所在带宽的占用情况等。第一BSS承载的无线站点越多,每个无线站点分配的资源越少,进而降低每个无线站点的通信效率。示例性的,第一BSS所在带宽的占用情况可以是第一BSS中每个连接占用第一BSS所在带宽的时间占比;在第一BSS中可以具有多个连接,每个连接的无线站点可以采用分时等方式占用第一BSS所在带宽,当第一BSS连接个数增加时,单个连接占用带宽的时间占比较低,则可以确定连接中无线站点被分配的资源较少。
预设阈值可以根据第二通信设备的通信业务对网络连接的要求设置。当第一BSS的负载量超出预设阈值,即当前网络连接无法满足第二通信设备的通信业务的需求时,可以将第一连接迁移至第二BSS上。
预设阈值也可以根据各BSS的负载情况设置。当第一BSS的负载量升高,引起各BSS的负载不均衡时,可以将第一连接迁移至第二BSS上。从而可以均衡建立的各个BSS负载。
如此,第一BSS的负载量达到预设阈值时,迁移第一连接,一方面,可以降低第一BSS的负载,提高通信质量。另一方面,可以均衡各个BSS的负载,提升通信质量。再一方面,可以使各个BSS占用的带宽资源都可以得到利用,进而提高第一通信设备带宽内频谱的利用率。
在一个实施例中,一个BSS的带宽等于第二通信设备的工作带宽与2 (M-1)相乘之积,且第二通信设备的工作带宽与2 (M-1)相乘之积小于或等于第一通信设备支持的最大工作带宽,其中,M为大于或等于1的正整数。
第一通信设备可以将自身的最大工作带宽与第二通信设备的工作带宽进行比较。如果第一通信设备最大工作带宽大于第二通信设备的工作带宽,则可以将第二通信设备的工作带宽与2 (M-1)相乘之积,确定为建立BSS的带宽。在第一通信设备最大工作带宽上建立N个BSS。第一连接可以是配置在N个BSS中第一BSS上的连接。
BSS的带宽可以是第二通信设备的工作带宽的1倍、2倍、4倍等。例如,第二通信设备的工作带宽为20MHz,则第一通信设备建立的BSS的带宽可以是20MHz、40MHz、80MH或160MHz。
M可以由第一设备根据的传输环境等确定,例如,第一通信设备上连接设备的数量不多,第一通信设备有带宽有剩余时,M可以取较大的值,使得建立的BSS的带宽可以支持较大的带宽进行数据传输。
如此,建立的N个BSS可以满足第一连接对带宽的需求。
在一个实施例中,N可以采用表达(1)式表示:
Figure PCTCN2019123751-appb-000005
其中,B 1max表示第一通信设备支持的最大工作带宽;B 2表示第二通信设备的工作带宽。
一般Wi-Fi设备的工作带宽为20MHz、40MHz、80MHz、160MHz或320MHz中的一种。如果第一通信设备的最大工作带宽为320MHZ,第二通信设备的工作带宽为20MHz,则第二通信设备的工作带宽与2 (M-1)之积为20MHz、40MHz、80MHz或160MHz,如此,第一通信设备分别可以建立16个,8个,4个或2个BSS。
在一个实施例中,第二通信设备的工作带宽,包括以下至少以下之一:第二通信设备当前使用的工作带宽;第二通信设备支持的最大工作带宽。
第一通信设备可以将第二通信设备当前使用的工作带宽或第二通信设备支持的最大工作带宽作为建立的BSS的带宽,如此,建立的每个BSS可以满足第二通信设备对带宽的需求。
当第一消息帧包含指示第二通信设备当前使用的工作带宽的第一信息元素时,第一通信设备可以以第二通信设备当前使用的工作带宽作为建立的BSS的带宽,建立多个BSS。当第二通信设备当前所在第一BSS的负载量达到预设阈值时,第一通信设备可以将与第二通信设备之间的第一连接 迁移到多个BSS中的第二BSS。第二BSS的带宽和第一BSS的带宽相同,因次,不会影响第一连接的数据传输。
当第一消息帧包含指示第二通信设备支持的最大工作带宽的第一信息元素时,第一通信设备可以以第二通信设备支持的最大工作带宽作为建立的BSS的带宽,建立多个BSS。当第二通信设备当前所在第一BSS的负载量达到预设阈值时,第一通信设备可以将与第二通信设备之间的第一连接迁移到多个BSS中的第二BSS。第二BSS的带宽和第一BSS的带宽相同,因次,不会影响第一连接的数据传输。同时由于第二BSS的带宽为第二通信设备支持的最大工作带宽,大于或等于第二通信设备当前的工作带宽,因此,第二通信设备可以在第二BSS中采用更大的工作带宽进行通信。
第一通信设备还可以根据第二通信设备支持的最大工作带宽,提供最优的工作带宽建立与第二通信设备的连接。
当第一消息帧包含指示第二通信设备当前使用的工作带宽和支持的最大工作带宽的第一信息元素时,第一通信设备可以根据实际情况选择第二通信设备当前使用的工作带宽或支持的最大工作带宽作为建立的BSS的带宽。示例性的,当传输环境不能满足第二通信设备采用支持的最大工作带宽进行传输时,可以采用二通信设备当前使用的工作带宽作为建立的BSS的带宽。
在一个实施例中,方法还包括:发送第二消息帧,其中,第一消息帧包含指示第一通信设备支持的最大工作带宽的第二信息元素。
第二消息帧可以是Wi-Fi通信技术中由第一无线通信设备发送的管理帧。第一通信设备可以在与第二通信设备进行关联或重关联过程中,在响应第一消息帧是,发送包含第二信息元素的第二消息帧。
示例性的,第一无线通信设备发送的管理帧可以包括:探测响应(Probe Response)帧、信标(Beacon)帧、关联响应(Association Response)帧或 认证响应(Authentication Response)帧等。
第二消息帧可以是第一消息帧的响应帧,第一消息帧和第二消息帧的对应关系可以如表1所示:

第一通信设备可以在第二消息帧中携带第二信息元素,用于指示无线接入点支持的工作带宽。
可以在第一通信设备的管理帧的帧主体的预设次序位置设置第二信息元素。示例性的,如图5a所示,可以在信标帧次序68的位置设置第二信息元素。如图5b所示,可以在关联响应帧次序31的位置设置第二信息元素。如图5c所示,可以在认证响应帧次序18的位置设置第二信息元素。
在一个实施例中,第二信息元素包括:第二信息元素标识,用于标识第二信息元素;第二长度标识,用于标识第二信息元素的长度;第二工作带宽标识,用于标识第一通信设备支持的最大工作带宽。

在一个实施例中,第一信息元素包括:第一信息元素标识,用于标识第一信息元素;第一长度标识,用于标识第一信息元素的长度;第一工作带宽标识,用于标识第二通信设备当前使用的工作带宽,和/或第二通信设备支持的最大工作带宽。

如图7所示,本示例性实施例提供一种于通信连接配置方法,可以应用于无线通信的第二通信设备中,该方法包括:
步骤201:发送第一消息帧,其中,第一消息帧包含:指示第二通信设备的工作带宽的第一信息元素。
第一通信设备可以是Wi-Fi无线通信中的无线接入点(AP,Access Point),第二通信设备可以是Wi-Fi无线通信中的无线站点(STA,Station)。
第一消息帧可以是Wi-Fi通信技术中由第二无线通信设备发送的管理帧。第二通信设备可以在与第一通信设备进行关联或重关联过程中发送包含第一信息元素的第一消息帧。其中,第二通信设备可以在与第一通信设备链路验证后进行关联,以便获得网络的访问权。关联属于一种记录保持过程,可以使第一通信设备能够记录第二通信设备,以便将传送给第二通信设备的帧送给正确的第二通信设备。重关联过程是指第二通信设备与第一通信设备脱离关联关系后,再次进行关联的过程。
示例性的,第一消息帧还可以第二无线通信设备发送的数据帧。示例 性的,第二无线通信设备发送的管理帧可以包括:探测请求(Probe Request)帧、关联请求(Association Request)帧或认证请求帧(Authentication Request)帧等。

如此,第二通信设备通过消息帧中的第一信息元素指示第二通信设备的工作带宽,提供了一种工作带宽的显性指示方式,第一通信设备可以直接根据包含消息帧中的第一信息元素确定第二通信设备的工作带宽,不需要额外指令对第二通信设备的工作带宽进行查询,提高消息帧包含的信息量,提升获取第二通信设备的工作带宽的便捷程度。
在一个实施例中,发送第一消息帧,包括:通过与第一通信设备之间的第一连接发送第一消息帧;其中,第一连接配置在N个基本服务集BSS中的第一BSS上,其中,N个基本服务集BSS是由第一通信设备基于第二通信设备的工作带宽及第一通信设备支持的最大工作带宽建立的;其中,N为正整数。
第一连接是第一通信设备和第二通信设备之前当前的Wi-Fi连接。BSS基本服务集是Wi-Fi通信网络的基本组件,用于描述在Wi-Fi网络中的一组相互通信的通信设备。
可以在第一通信设备支持的最大工作带宽范围内设置N个BSS。每个 BSS的带宽可以根据第二通信设备的工作带宽设置,使得每个BSS可以都可以满足第一通信设备和第二通信设备之前的连接的需求。
示例性的,可以以第二通信设备的当前工作带宽作为每个BSS的带宽。如此,可以将第一连接配置到BSS中。
在一个实施例中,如图8所示,通信连接配置方法还可以包括步骤202:当第一BSS的负载量达到预设阈值时,通过迁移至N个BSS中的第二BSS上的第一连接与第一通信设备进行通信;
其中,第二BSS不同于第一BSS。
这里,第一BSS的负载量可以包括:和第一BSS承载的无线站点等通信设备的数量、和/或第一BSS所在带宽的占用情况等。第一BSS承载的无线站点越多,每个无线站点分配的资源越少,进而降低每个无线站点的通信效率。示例性的,第一BSS所在带宽的占用情况可以是第一BSS中每个连接占用第一BSS所在带宽的时间占比;在第一BSS中可以具有多个连接,每个连接的无线站点可以采用分时等方式占用第一BSS所在带宽,当第一BSS连接个数增加时,单个连接占用带宽的时间占比较低,则可以确定连接中无线站点被分配的资源较少。
预设阈值可以根据第二通信设备的通信业务对网络连接的要求设置。当第一BSS的负载量超出预设阈值,即当前网络连接无法满足第二通信设备的通信业务的需求时,可以将第一连接迁移至第二BSS上。
预设阈值也可以根据各BSS的负载情况设置。当第一BSS的负载量升高,引起各BSS的负载不均衡时,可以将第一连接迁移至第二BSS上。从而可以均衡建立的各个BSS负载。
如此,第一BSS的负载量达到预设阈值时,迁移第一连接,一方面,可以降低第一BSS的负载,提高通信质量。另一方面,可以均衡各个BSS的负载,提升通信质量。再一方面,可以使各个BSS占用的带宽资源都可 以得到利用,进而提高第一通信设备带宽内频谱的利用率。
在一个实施例中,一个BSS的带宽等于第二通信设备的工作带宽与2 (M-1)相乘之积,且第二通信设备的工作带宽与2 (M-1)相乘之积小于或等于第一通信设备支持的最大工作带宽,其中,M为大于或等于1的正整数。
第一通信设备可以将自身的最大工作带宽与第二通信设备的工作带宽进行比较。如果第一通信设备最大工作带宽大于第二通信设备的工作带宽,则可以将第二通信设备的工作带宽与2 (M-1)相乘之积,确定为建立BSS的带宽。在第一通信设备最大工作带宽上建立N个BSS。第一连接可以是配置在N个BSS中第一BSS上的连接。
BSS的带宽可以是第二通信设备的工作带宽的1倍、2倍、4倍等。例如,第二通信设备的工作带宽为20MHz,则第一通信设备建立的BSS的带宽可以是20MHz、40MHz、80MH或160MHz。
M可以由第一设备根据的传输环境等确定,例如,第一通信设备上连接设备的数量不多,第一通信设备有带宽有剩余时,M可以取较大的值,使得建立的BSS的带宽可以支持较大的带宽进行数据传输。
如此,建立的N个BSS可以满足第一连接对带宽的需求。
在一个实施例中,N可以采用表达(1)式表示。其中,B 1max表示第一通信设备支持的最大工作带宽;B 2表示第二通信设备的工作带宽。
一般Wi-Fi设备的工作带宽为20MHz、40MHz、80MHz、160MHz或320MHz中的一种。如果第一通信设备的最大工作带宽为320MHZ,第二通信设备的工作带宽为20MHz,则第二通信设备的工作带宽与2 (M-1)之积为20MHz、40MHz、80MHz或160MHz,如此,第一通信设备分别可以建立16个,8个,4个或2个BSS。
在一个实施例中,第二通信设备的工作带宽,包括以下至少以下之一:第二通信设备当前使用的工作带宽;第二通信设备支持的最大工作带宽。

当第一消息帧包含指示第二通信设备当前使用的工作带宽的第一信息元素时,第一通信设备可以以第二通信设备当前使用的工作带宽作为建立的BSS的带宽,建立多个BSS。当第二通信设备当前所在第一BSS的负载量达到预设阈值时,第一通信设备可以将与第二通信设备之间的第一连接迁移到多个BSS中的第二BSS。第二BSS的带宽和第一BSS的带宽相同,因次,不会影响第一连接的数据传输。
当第一消息帧包含指示第二通信设备支持的最大工作带宽的第一信息元素时,第一通信设备可以以第二通信设备支持的最大工作带宽作为建立的BSS的带宽,建立多个BSS。当第二通信设备当前所在第一BSS的负载量达到预设阈值时,第一通信设备可以将与第二通信设备之间的第一连接迁移到多个BSS中的第二BSS。第二BSS的带宽和第一BSS的带宽相同,因次,不会影响第一连接的数据传输。同时由于第二BSS的带宽为第二通信设备支持的最大工作带宽,大于或等于第二通信设备当前的工作带宽,因此,第二通信设备可以在第二BSS中采用更大的工作带宽进行通信。
第一通信设备还可以根据第二通信设备支持的最大工作带宽,提供最优的工作带宽建立与第二通信设备的连接。
当第一消息帧包含指示第二通信设备当前使用的工作带宽和支持的最大工作带宽的第一信息元素时,第一通信设备可以根据实际情况选择第二通信设备当前使用的工作带宽或支持的最大工作带宽作为建立的BSS的带宽。示例性的,当传输环境不能满足第二通信设备采用支持的最大工作带宽进行传输时,可以采用二通信设备当前使用的工作带宽作为建立的BSS的带宽。

示例性的,第一无线通信设备发送的管理帧可以包括:探测响应(Probe Response)帧、信标(Beacon)帧、关联响应(Association Response)帧或认证响应(Authentication Response)帧等。
第二消息帧可以是第一消息帧的响应帧,第一消息帧和第二消息帧的对应关系可以如表1所示。
第一通信设备可以在第二消息帧中携带第二信息元素,用于指示无线接入点支持的工作带宽。
可以在第一通信设备的管理帧的帧主体的预设次序位置设置第二信息元素。示例性的,如图5a所示,可以在信标帧次序68的位置设置第二信息元素。如图5b所示,可以在关联响应帧次序31的位置设置第二信息元素。如图5c所示,可以在认证响应帧次序18的位置设置第二信息元素。
在一个实施例中,第二信息元素包括:第二信息元素标识,用于标识第二信息元素;第二长度标识,用于标识第二信息元素的长度;第二工作带宽标识,用于标识第一通信设备支持的最大工作带宽。
第二信息元素的格式可以如图5所示,示例性的,传输环境可以占用3个字节。第二信息元素标识可以占用1个字节,第二信息元素标识用于标识信息元素。第二长度标识可以占用1个字节。第二工作带宽标识占用1个字节,可以采用二进制数表示第一通信设备支持的最大工作带宽。
在一个实施例中,第一信息元素包括:第一信息元素标识,用于标识第一信息元素;第一长度标识,用于标识第一信息元素的长度;第一工作 带宽标识,用于标识第二通信设备当前使用的工作带宽,和/或第二通信设备支持的最大工作带宽。

第一工作带宽标识可以包括两个部分,第一部分为标识第二通信设备当前使用的工作带宽,可以用三个比特位标识表示20MHz、40MHz、80MHz、160MHz或320MHz中的一种。第二部分为标识第二通信设备支持的最大工作带宽,可以用三个比特位标识表示20MHz、40MHz、80MHz、160MHz或320MHz中的一种,第一工作带宽标识中剩余的另两个比特位可以作为保留位。
以下结合上述任意实施例提供一个具体示例:
1、最大工作带宽支持指示。
a、在无线站点与无线接入点初始连接的过程中,无线站点与无线接入点在初始连接联消息帧中都可以携带其支持最大工作带宽的指示信息,具体为:
无线接入点:可以在探测响应(Probe Response)帧、信标(Beacon)帧、关联响应(Association Response)帧或认证响应(Authentication Response)帧中携带无线接入点支持的最大工作带宽,具体可以在帧体(frame body)部分携带无线接入点支持的最大工作带宽。
示例性的,可以在如图5a所示的信标帧的次序68的位置、如图5b所示的关联响应帧的次序31的位置、或如图5c所示的认证响应帧的次序18的位置携带无线接入点支持的最大工作带宽。
无线站点:可以在探测请求(Probe Request)帧、关联请求(Association Request)帧或认证请求帧(Authentication Request)帧等中携带无线站点支持的最大工作带宽,具体可以在帧体(frame body)部分携带无线站点支持的最大工作带宽。
示例性的,可以在如图3a所示的探测请求帧的次序20的位置、如图3b所示的关联请求帧的次序24的位置、或如图3c所示的认证请求帧的次序18的位置携带无线站点支持的最大工作带宽。
b、支持最大工作带宽信息元素格式。
无线站点与无线接入点可以采用相似的信息元素格式指示最大工作带宽,具体格式如图6所示。其中元素标识(Element ID)定义了一种新的信息元素,长度(Length)标识信息元素长度,元素信息(Element Information)可分为两个部分:第一部分为:当前工作的信道带宽,用三个比特位标识20/40/80/160/160+80/160+160/320MHz,第二部分为:可支持的最大带宽,也用三个比特位标识20/40/80/160/160+80/160+160/320MHz,另两个比特位为保留位。
2、具体实现方式:
无线站点和无线接入点在初始接入过程中,分别发送消息帧,携带上述信息元素。无线站点在接收到无线接入点发送的信标帧后,解析无线接入点的支持的最大工作带宽的信息元素,并发送认证请求帧。认证请求帧中设置的无线站点的当前带宽一般为20MHz或者更大,当无线接入点接收到无线站点发送的认证请求帧后,解析得到无线站点支持的最大工作带宽。如无线站点支持的最大工作带宽小于无线接入点支持的最大工作带宽,则无线接入点可以根据建立的BSS的负载情况,在数据通信时将已经建立初始连接的无线站点搬迁到另外的BSS进行数据通信。
示例性的:无线站点与无线接入点在20MHz的带宽下建立了初始连接, 且站点无线站点支持的最大工作带宽为20MHz,而无线接入点所支持的最大工作带宽为80MHz,那么无线接入点则可建立4个BSS,根据每个BSS中的负载情况搬迁无线站点至任意建立的BSS(建立初始连接的BSS除外)中进行数据通信。无线接入点可根据无线站点当前建立初始连接的信道带宽来确认其建立的BSS数量,具体为:BSS数量为无线接入点所支持的最大工作带宽除以无线站点当前工作带宽之商;或者,BSS数量为无线接入点所支持的最大工作带宽除以两倍的无线站点当前工作带宽之商;BSS数量为无线接入点所支持的最大工作带宽除以四倍的无线站点当前工作带宽之商。其中,建立的BSS数量的个数根据无线站点当前工作带宽和无线接入点最大工作带宽来确定。
