具体实施方式
本公开实施例提出了一种通信方法、接入点设备、站点设备及通信设备。
第一方面，本公开实施例提出了一种通信方法，所述方法包括：
接入点设备确定第一无线帧；其中，所述第一无线帧包括第一标识信息，所述第一标识信息包括所述接入点设备的第一侦听能力信息；
所述第一侦听能力信息标识：所述接入点设备是否支持站点设备侦听辅助信道；
发送所述第一无线帧。
在上述实施例中，当主信道处于繁忙时，WLAN设备能够在辅助信道中进行通信，以提高通信系统吞吐量，实现信道资源利用最大化。
结合第一方面的一些实施例，在一些实施例中，所述第一侦听能力信息标识所述接入点设备支持站点设备侦听辅助信道，
所述第一标识信息还包括：第一侦听周期信息，所述第一侦听周期信息包括所述接入点设备所支持的站点设备侦听辅助信道的侦听周期信息。
在上述实施例中，侦听周期可以是0ms(毫秒)、2.7ms或4ms，或其他时间值。所述第一侦听能力信息中还标识所述接入点设备支持的站点设备侦听周期时间，或接入点设备最终确定的侦听周期时间，通过协商侦听周期时间，进一步完善WLAN设备在辅助信道通信的机制，以提高通信系统吞吐量。
结合第一方面的一些实施例，在一些实施例中，所述第一无线帧包括信标beacon帧、探测响应probe response帧、关联响应association response帧或新定义的无线帧中的至少一种；
所述第一侦听周期信息携带在所述association response帧中；
所述新定义的无线帧为初始关联之后发送的无线帧。
在上述实施例中，在初始关联过程中，接入点设备与站点设备通过前述beacon帧、probe response帧、应association response帧中的至少一种来协商接入点设备的侦听能力信息；所述新定义的无线帧为初始关联之后发送的无线帧，在初始关联之后，通过新定义的无线帧来协商接入点设备的侦听能力信息，以提高通信系统吞吐量。
结合第一方面的一些实施例，在一些实施例中，所述第一侦听周期信息包括多个所述辅助信道的侦听周期时间；
每个所述辅助信道的侦听周期时间相同，或至少两个带宽不同的所述辅助信道的侦听周期时间不同。
在上述实施例中，辅助信道可以包含一个或多个。例如，若以20MHz为基本带宽单位进行划分，当信道带宽为20MHz时，仅具有一个带宽为20MHz的主信道；当信道带宽大于20MHz时，包含一个带宽为20MHz的信道为主信道，其余的一个或多个20MHz信道为辅助信道。对于不同的辅助信道，每个所述辅助信道的侦听周期时间可以相同，例如采用2.7ms或4ms；也可以存在至少两个带宽不同的所述辅助信道的侦听周期时间不同，例如，20MHz的辅助信道侦听周期为2.7ms，40MHz的辅助信道侦听周期为4ms。通过协商侦听周期时间，进一步完善WLAN设备在辅助信道通信的机制，以提高通信系统吞吐量。

如图1所示，在WLAN中，信道通常分为主信道和辅助信道(secondary channel或non-primary channel，或称为次信道、非主信道)；主信道例如图1中主20MHz信道；其中，辅助信道可以包含一个或多个子信道，例如图1中20MHz辅助信道和40MHz辅助信道。
在信道上进行信道竞争的过程，若主信道处于OBSS繁忙状态(OBSS干扰)，如图中T1时间段与T2时间段所示，例如被与WLAN处于同一OBSS中的其他设备所占据，其他设备在主信道上发送物理层协议数据单元(physical protocol data unit，PPDU)，则该主信道处于OBSS繁忙状态。若主信道处于OBSS繁忙状态，为了能够充分利用信道资源，则可切换到辅助信道通信，以提高通信系统吞吐量，实现信道资源利用最大化。例如，在T1时间段切换到20MHz辅助信道通信，或在T2时间段切换到40MHz辅助信道通信.
若主信道处于空闲状态，如图中T3时间段所示，则AP与STA之间可以互相发送PPDU.
图2是根据本公开实施例示出的通信系统的架构示意图。
如图2所示，通信系统100包括站点设备(Station，STA)101、接入点设备(Access Point，AP)102。
在一些实施例中，站点设备101例如包括支持WiFi通讯功能的无线通讯芯片、无线传感器或无线通信终端。可选地，无线通信终端例如手机(mobile phone)、可穿戴设备、支持WiFi通讯功能的物联网设备、具备WiFi通讯功能的汽车、智能汽车、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备中的至少一者，但不限于此。
具体地，站点设备101可以是带有无线保真(WiFi)芯片的终端设备或者网络设备。可选的，站点设备101可以支持802.11ax、802.11be、802.11ac、802.11n、802.11g、802.11b及802.11a、802.11bf、802.11bn等多种WLAN制式，以及支持下一代802.11协议，但不限于此。
在一些实施例中，接入点设备102可以是移动终端进入有线网络的接入点。AP相当于一个连接有线网和无线网的桥梁，其主要作用是将各个无线网络客户端连接到一起，然后将无线网络接入以太网。具体地，AP可以是带有无线保真芯片的终端设备或者网络设备。可选的，AP可以支持802.11ax、802.11be、802.11ac、802.11n、802.11g、802.11b及802.11a、802.11bf、802.11bn等多种WLAN制式，以及支持下一代802.11协议，但不限于此。
可选地，在本公开实施例中，AP和STA可以为支持多连接的设备，例如，可以被分别表示为多连接入点设备(Access Point Multi-Link Device，AP MLD)和多连站点设备(Non-Access Point Multi-Link Device，Non-AP MLD)；AP MLD可以表示支持多连接通信功能的接入点，non-AP MLD可以表示支持多连接通信功能的站点。
可以理解的是，本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提出的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提出的技术方案对于类似的技术问题同样适用。
下述本公开实施例可以应用于图2所示的通信系统100、或部分主体，但不限于此。图2所示的各主体是例示，通信系统可以包括图2中的全部或部分主体，也可以包括图2以外的其他主体，各主体数量和形态为任意，各主体可以是实体的也可以是虚拟的，各主体之间的连接关系是例示，各主体之间可以不连接也可以连接，其连接可以是任意方式，可以是直接连接也可以是间接连接，可以是有线连接也可以是无线连接。
本公开各实施例可以应用于无线局域网(Wireless Local Area Network，WLAN)，例如采用802.11系列协议的局域网。在WLAN中，基本服务集(BSS，Basic Service Set)是一个WLAN的基本组成部分。BSS网络是由某一特定覆盖区域之内具有某种关联的站点设备组成。关联的一种情形是站点在一个自组网络中相互直接通信，这被称为独立BSS(IBSS，Independent Basic Service Set)。另一种更常见的情形是在BSS网络中只有一个具有专职管理BSS的中央站点被称为接入点设备，而在该网络中的其它STA都与它相关联。在BSS网络中的不是中央站点的其它站点被称之为终端，也称之为non-AP STA，终端和non-AP STA统称之为STA。当描述STA时不需要区分AP和non-AP STA。在同一个BSS网络中，由于距离、发送功率等原因，一个STA无法检测离其较远的其他STA，两者互为对方的隐藏节点。
如图2所示，上述方法包括：
步骤201，接入点设备102确定第一无线帧；其中，所述第一无线帧包括第一标识信息，所述第一标识信息包括所述接入点设备的第一侦听能力信息；所述第一侦听能力信息标识：所述接入点设备是否支持站点设备侦听辅助信道。
在WLAN中，信道通常分为主信道和辅助信道(secondary channel或non-primary channel，或称为次信道、非主信道)；其中，辅助信道可以包含一个或多个子信道。例如，若以20MHz为基本带宽单位进行划分，当信道带宽为20MHz时，仅具有一个带宽为20MHz的主信道；当信道带宽大于20MHz时，包含一个带宽为20MHz的信道为主信道，其余的一个或多个20MHz信道为辅助信道。主20MHz信道为属于一个BSS中的成员的公共操作信道(The common channel of operation for stations that are members of the basicservice set)，BSS中的站点可在主20MHz信道上进行信道竞争，以抢占信道资源。
在信道上进行信道竞争的过程，若主信道处于OBSS繁忙状态，例如被与接入点设备102处于同一OBSS中的其他设备所占据，其他设备在主信道上发送物理层协议数据单元(physical protocol data unit，PPDU)，则该主信道处于OBSS繁忙状态。若主信道处于OBSS繁忙状态，为了能够充分利用信道资源，则可切换到辅助信道与站点设备101通信，将站点设备101调度到辅助信道上，并与站点设备101进行数据的发送和接收，以提高通信系统吞吐量，实现信道资源利用最大化。
本公开实施例中，为了实现主信道繁忙时切换到辅助信道进行通信，接入点设备102在第一无线帧中标识其第一侦听能力信息，且第一侦听能力信息标识所述接入点设备102是否支持站点设备101侦听(sense)辅助信道。
通常情况下，网络上各个站点设备在发送数据前都要侦听信道上有没有其他数据在传输，例如通过载波侦听(carrier sense)机制实现。在即将切换到辅助信道进行通信时，接入点设备102会通知站点设备101，例如通过向站点设备101发送请求发送(request to send，RTS)帧或缓冲区状态报告轮询(buffer status report poll，BSRP)控制帧来实现。而在接入点设备102发送RTS帧或BSRP控制帧时，站点设备101需要在辅助信道侦听才能接收到所述RTS帧或BSRP控制帧；因此，实现实现主信道繁忙时切换到辅助信道进行通信，需要接入点设备102支持站点设备101侦听(sense)辅助信道。
所述第一侦听能力信息标识：所述接入点设备是否支持站点设备侦听辅助信道；例如，在第一侦听能力信息中设置第一标识位，若第一标识位设置为“1”，标识接入点设备102支持站点设备101侦听辅助信道，后续可以在主信道繁忙时切换到辅助信道进行通信；若第一标识位设置为“0”，标识接入点设备102不支持站点设备101侦听辅助信道，后续在主信道繁忙时不能切换到辅助信道进 行通信。
可选地，所述第一无线帧可以是接入点设备102与站点设备101在初始关联过程中发送的帧，例如信标beacon帧、探测响应probe response帧、关联响应association response帧或新定义的无线帧中的至少一种；还可以在初始关联之后，新定义一个无线帧用来承载所述第一标识信息。
步骤202，接入点设备102发送所述第一无线帧。
其中，接入点设备102发送所述第一无线帧。这样，当主信道处于繁忙时，WLAN设备能够在辅助信道中进行通信。例如，接入点设备102和站点设备101之间出现非周期性的数据传输，或接入点设备102有下行数据需发送给站点设备101时，WLAN设备感知主信道繁忙时，可切换至辅助信道发送RTS或BSRP控制帧，站点设备101辅助信道进行侦听，向接入点设备102回复清除发送(clear to send，CTS)帧，使得接入点设备102根据CTS帧确认辅助信道为空闲状态，可以发送数据，进而实现在辅助信道中进行通信，以提高通信系统吞吐量，实现信道资源利用最大化。
步骤203，站点设备101接收所述第一无线帧。
站点设备101接收到第一无线帧之后，根据第一侦听能力信息确定接入点设备102是否支持站点设备侦听辅助信道；若支持(且站点设备101自身也支持)，则在辅助信道执行侦听，例如通过空闲信道评估(clear channel assessment，CCA)操作、能量检测(energy detection，ED)操作或网络分配矢量(network allocation vector，NAV)操作侦听。
在一些实施例中，所述第一侦听能力信息标识所述接入点设备支持站点设备侦听辅助信道，
所述第一标识信息还包括：第一侦听周期信息，所述第一侦听周期信息包括所述接入点设备所支持的站点设备侦听辅助信道的侦听周期信息。
其中，侦听周期可以是0ms(毫秒)、2.7ms或4ms，或其他时间值。所述第一侦听能力信息中还标识所述接入点设备102支持的站点设备101侦听周期时间，或接入点设备102最终确定的侦听周期时间。
在一些实施例中，所述第一无线帧包括信标beacon帧、探测响应probe response帧、关联响应association response帧或新定义的无线帧中的至少一种；例如，在初始关联过程中，接入点设备102与站点设备101通过前述beacon帧、probe response帧、应association response帧中的至少一种来协商接入点设备102的侦听能力信息；所述新定义的无线帧为初始关联之后发送的无线帧，在初始关联之后，通过新定义的无线帧来协商接入点设备102的侦听能力信息。
所述第一侦听周期信息携带在所述关联响应association response帧中，例如，通过association response确定最终执行的侦听周期时间。
在一些实施例中，所述第一侦听周期信息包括多个所述辅助信道的侦听周期时间；
每个所述辅助信道的侦听周期时间相同，或至少两个带宽不同的所述辅助信道的侦听周期时间不同。
其中，辅助信道可以包含一个或多个。
例如，若以20MHz为基本带宽单位进行划分，当信道带宽为20MHz时，仅具有一个带宽为20MHz的主信道；当信道带宽大于20MHz时，包含一个带宽为20MHz的信道为主信道，其余的一个或多个20MHz信道为辅助信道。对于不同的辅助信道，每个所述辅助信道的侦听周期时间可以相同，例如采用2.7ms或4ms，便于WLAN设备对不同信道侦听周期做统一管理；也可以存在至少两个带宽不同的所述辅助信道的侦听周期时间不同，例如，20MHz的辅助信道侦听周期为2.7ms，40MHz的辅助信道侦听周期为4ms，对于不同带宽的信道，设置不同的侦听周期时间，减少相互之间的干扰。
在一些实施例中，所述第一侦听周期信息中包括所述辅助信道与主信道之间的带宽差值，每个所述带宽差值对应预设的侦听周期时间。
其中，可以通过辅助信道的带宽与主信道带宽之间的差值，来决定辅助信道的侦听周期；例如，建立带宽差值与侦听周期差值之间的映射关系，辅助信道带宽与主信道带宽之间每相差20MHz，侦听周期时长增加1ms，或侦听周期之间的间隔增加1ms。
在一些实施例中，所述第一侦听周期信息包括所述辅助信道的侦听周期时间；
所述侦听周期时间为主信道的负载BSS loading信息中配置的值。
其中，可以根据在主信道中的BSS loading信息，AP与STA调整其侦听周期信息为固定的侦听 周期；例如，选择BSS loading信息中的一个配置的的值，作为最终执行的侦听周期时间。
在一些实施例中，所述第一侦听周期信息包括所述辅助信道的侦听周期时间；
所述辅助信道的侦听周期时间不同于其他BSS的侦听周期时间，所述其他BSS为与所述接入点设备处于同一OBSS中的BSS。
其中，接入点设备102与站点设备101最终确定的本BSS的侦听周期不同于其他BSS的侦听周期时间，避免与其他BSS之间形成干扰。此外，接入点设备102向处于OBSS中的其他WLAN设备广播其协商的侦听时间周期，便于其他WLAN设备根据接收到的其他BSS的侦听周期来，确定本BSS的侦听周期。
图3是根据本公开实施例示出的通信方法的交互示意图之二。如图3所示，上述方法包括：
步骤301，站点设备101确定第二无线帧；其中，所述第二无线帧包括第二标识信息，所述第二标识信息包括所述站点设备的第二侦听能力信息；所述第二侦听能力信息包括：所述站点设备是否支持侦听辅助信道。
在WLAN中，信道通常分为主信道和辅助信道(secondary channel或non-primary channel，或称为次信道、非主信道)；其中，辅助信道可以包含一个或多个子信道。例如，若以20MHz为基本带宽单位进行划分，当信道带宽为20MHz时，仅具有一个带宽为20MHz的主信道；当信道带宽大于20MHz时，包含一个带宽为20MHz的信道为主信道，其余的一个或多个20MHz信道为辅助信道。主20MHz信道为属于一个BSS中的成员的公共操作信道(The common channel of operation for stations that are members of the basicservice set)，BSS中的站点可在主20MHz信道上进行信道竞争，以抢占信道资源。
在信道上进行信道竞争的过程，若主信道处于OBSS繁忙状态，例如被与接入点设备102处于同一OBSS中的其他设备所占据，其他设备在主信道上发送物理层协议数据单元(physical protocol data unit，PPDU)，则该主信道处于OBSS繁忙状态。若主信道处于OBSS繁忙状态，为了能够充分利用信道资源，则可切换到辅助信道与站点设备101通信，将站点设备101调度到辅助信道上，并与站点设备101进行数据的发送和接收，以提高通信系统吞吐量，实现信道资源利用最大化。
本公开实施例中，为了实现主信道繁忙时切换到辅助信道进行通信，接入点设备102在第二无线帧中标识其第二侦听能力信息，且第二侦听能力信息标识所述站点设备是否支持侦听(sense)辅助信道。
通常情况下，网络上各个站点设备在发送数据前都要侦听信道上有没有其他数据在传输，例如通过载波侦听(carrier sense)机制实现。在即将切换到辅助信道进行通信时，接入点设备102会通知站点设备101，例如通过向站点设备101发送请求发送(request to send，RTS)帧或缓冲区状态报告轮询(buffer status report poll，BSRP)控制帧来实现。而在站点设备101发送RTS帧或BSRP控制帧时，站点设备101需要在辅助信道侦听才能接收到所述RTS帧或BSRP控制帧；因此，实现实现主信道繁忙时切换到辅助信道进行通信，需要站点设备101支持侦听(sense)辅助信道。
所述第二侦听能力信息标识：所述站点设备是否支持侦听辅助信道；例如，在第二侦听能力信息中设置第二标识位，若第二标识位设置为“1”，标识站点设备101支持侦听辅助信道，后续可以在主信道繁忙时切换到辅助信道进行通信；若第二标识位设置为“0”，标识站点设备101不支持侦听辅助信道，后续在主信道繁忙时不能切换到辅助信道进行通信。
可选地，所述第二无线帧可以是接入点设备102与站点设备101在初始关联过程中发送的帧，例如探测响应probe request帧、关联响应association request帧或新定义的无线帧中的至少一种；还可以在初始关联之后，新定义一个无线帧用来承载所述第二标识信息。
步骤302，站点设备101发送所述第二无线帧。
其中，站点设备101发送所述第二无线帧。这样，当主信道处于繁忙时，WLAN设备能够在辅助信道中进行通信。例如，接入点设备102和站点设备101之间出现非周期性的数据传输，或接入点设备102有下行数据需发送给站点设备101时，WLAN设备感知主信道繁忙时，可切换至辅助信道发送RTS或BSRP控制帧，站点设备101辅助信道进行侦听，向接入点设备102回复清除发送(clear to send，CTS)帧，使得接入点设备102根据CTS帧确认辅助信道为空闲状态，可以发送数据，进而实现在辅助信道中进行通信，以提高通信系统吞吐量，实现信道资源利用最大化。
步骤303，接入点设备102接收所述第二无线帧。
接入点设备102接收到第二无线帧之后，根据第二侦听能力信息确定接入点设备102是否支持 站点设备侦听辅助信道；若支持(且站点设备101自身也支持)，则在辅助信道执行侦听，例如通过空闲信道评估(clear channel assessment，CCA)操作、能量检测(energy detection，ED)操作或网络分配矢量(network allocation vector，NAV)操作侦听。

在一些实施例中，所述第二无线帧包括probe request帧、association request帧或新定义的无线帧中的至少一种；例如，在初始关联过程中，接入点设备102与站点设备101通过前述、probe request帧、association request帧中的至少一种来协商接入点设备102的侦听能力信息；所述新定义的无线帧为初始关联之后发送的无线帧，在初始关联之后，通过新定义的无线帧来协商接入点设备102的侦听能力信息。

在一些实施例中，所述第二侦听周期信息包括多个所述辅助信道的侦听周期时间；
每个所述辅助信道的侦听周期时间相同，或至少两个带宽不同的所述辅助信道的侦听周期时间不同。
其中，辅助信道可以包含一个或多个。例如，若以20MHz为基本带宽单位进行划分，当信道带宽为20MHz时，仅具有一个带宽为20MHz的主信道；当信道带宽大于20MHz时，包含一个带宽为20MHz的信道为主信道，其余的一个或多个20MHz信道为辅助信道。对于不同的辅助信道，每个所述辅助信道的侦听周期时间可以相同，例如采用2.7ms或4ms，便于WLAN设备对不同信道侦听周期做统一管理；也可以存在至少两个带宽不同的所述辅助信道的侦听周期时间不同，例如，20MHz的辅助信道侦听周期为2.7ms，40MHz的辅助信道侦听周期为4ms，对于不同带宽的信道，设置不同的侦听周期时间，减少相互之间的干扰。

在一些实施例中，所述第二侦听周期信息包括所述辅助信道的侦听周期时间；
所述辅助信道的侦听周期时间不同于其他BSS的侦听周期时间，所述其他BSS为与所述站点设备处于同一OBSS中的BSS。
其中，接入点设备102与站点设备101最终确定的本BSS的侦听周期不同于其他BSS的侦听周期时间，避免与其他BSS之间形成干扰。此外，站点设备101向处于OBSS中的其他WLAN设备广播其协商的侦听时间周期，便于其他WLAN设备根据接收到的其他BSS的侦听周期来，确定本BSS的侦听周期。
