Description

通信方法及通信节点
本申请要求于2017年06月22日提交中国专利局、申请号为201710482865.X、申请名称为“通信方法及通信节点”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术，尤其涉及一种通信方法及通信节点。
背景技术
毫米波无线通信作为无线局域网通信的主要技术之一，由于毫米波频段的可用带宽很宽，可实现较高的通信效率。
而毫米波信道的信号衰减严重，路径损耗非常大，因此在毫米波通信中，需采用波束赋形(BeamForming，BF)训练进行收发波束的对齐，根据该对齐的收发波束进行数据收发可有效提高收发天线的增益用以克服信号衰减。
由于在毫米波信道也就是高频信道上进行波束赋形训练比较耗时，这使得毫米波通信的效率较低，其网络吞吐量受到限制。
发明内容
本申请提供一种通信方法及通信节点，以提高网络通信的效率和网络吞吐量。
在第一方面，本申请实施例提供一种通信方法，包括：
发送节点在第一信道上向接收节点发送第一帧；
该发送节点在第二信道上向该接收节点发送至少一个第二帧，其中，该第一信道的频率小于该第二信道的频率，每个该第二帧对应一个发送方向，每个该第二帧的长度小于预设帧长度。
该通信方法中，采用不同频率的信道进行协作通信以向接收节点发送信息，在频率较高的第二信道上发送至少一个对应一个发送方向的第二帧，在频率较低的第一信道上发送第一阵，由于该第一信道的分担协作，第二信道上传输的第二帧的长度小于预设帧长度，因而能降低第二信道上进行波束赋形训练时长，提高网络的整体通信效率和吞吐量。
并且，该通信方法中，该第一信道的频率较低，信号的衰减较小，路径损耗较小，因此将该第二信道上的待传输信息携带在该第一信道上发送的该第一帧中，可有效提高信息传输的鲁棒性，提高网络性能。
可选的，由于该通信方法中，发送节点需在第一信道上发送第一帧，因而在发送该第一帧之前，该发送节点需先对该第一信道进行空闲信道评估(Clear Channel Assessment，CCA)以确定该第一信道是否空闲(Clear)，若该第一信道空闲，则在该第一信道上发送 该第一帧。

具体实施方式
本申请各实施例提供的通信方法及发送节点，可适用于无线局域网(Wireless Local Area Networks，WLAN)系统，也可适用于移动通信系统或者其他移动通信标准对应的移动通信系统。若适用于WLAN系统，尤其适用于802.11ad标准、802.11ay标准及其标准的后续改进标准的WLAN系统。若适用于移动通信系统，则可尤其适应于5G通信系统或者后续其他的演进的移动通信系统。图1为本申请各实施例适用的一种网络系统的结构示意图。如图1所示，该波束处理方法适用的网络系统例如可包括一个网络设备、至少一个用户设备。其中，对于WLAN系统，该网络设备例如可以为基本服务集控制点(Personal Basic Service Set Control Point，PCP)/接入点(Access Point，AP)。用户设备可以为站点(STAtion，STA)。对于移动通信系统，该网络设备例如可以为基站，如基本传输站(Base Transceiver Station，BTS)、基本站点(Node Base，NodeB)、演进型基站(evolutional Node B，eNB)等任一，本申请并不限定。该用户设备可以为订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动台(Mobile)、远程站(Remote Station)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户装备(User Equipment，UE)等任一。
参见图1可知，不同频率信道的信号传输距离不同，即其覆盖范围不同。其中，具有BF训练的高频信道的覆盖范围，大于无BF训练的高频信道的覆盖范围，而低频信道的覆盖范围可大于该具有BF训练的高频信道的覆盖范围。
本申请如下各实施例所涉及的发送节点可以为网络设备，也可以为用户设备，该接收节点可以为网络设备，也可以为用户设备。例如，若发送节点为网络设备，则该接收节点为用户设备或网络设备；若该发送节点为用户设备，则该接收节点可以为网络设备或用户 设备。
在一种实现方式中，本申请下述各实施例所涉及的网络设备可以为双模网络设备，也就是具有低频(Low Frequency，LF)信道通信模式，和高频(High Frequency，HF)信道通信模式的网络设备。图2为本申请实施例提供的一种网络设备的结构示意图。如图2所示，该网络设备包括控制器(controller)、HF模块及LF模块。其中，该控制器可存储有HF模块和LF模块的公共信息(common info)。HF模块可包括：HF介质访问控制(Media Access Control，MAC)层模块和HF物理(PHY)层模块；LF模块可包括：LF MAC层模块和LF PHY层模块。控制器可对该HF模块和该LF模块进行控制和协调。该HF模块和该LF模块可位于网络设备内的同一个芯片中，也可分别位于一个独立的芯片中。
本申请下述各实施例所涉及的用户设备可以为双模用户设备，也就是具有LF信道通信模式和HF信道通信模式的网络设备。图3为本申请实施例提供的一种用户设备的结构示意图。如图3所示，该用户设备包括控制器(controller)、HF模块及LF模块。其中，该控制器可存储有HF模块和LF模块的公共信息。HF模块可包括：HF MAC层模块和HF PHY层模块；LF模块可包括：LF MAC层模块和LF PHY层模块。控制器可对该HF模块和该LF模块进行控制和协调。该HF模块和该LF模块可位于用户设备内的同一个芯片中，也可分别位于一个独立的芯片中。
在又一种实现方式中，本申请下述各实施例所涉及的网络设备也可以为单模网络设备，即具有HF通信模式的网络设备，对于HF通信模式的网络设备其可包括控制器和HF模块，其中，HF模块可包括：HF MAC层模块和HF PHY层模块。控制器可对该HF模块进行控制。所涉及的用户设备还可以为单模用户设备，即具有HF通信模式的用户设备，对于HF通信模式的网络设备，其可包括控制器和HF模块，其中，HF模块可包括：HF MAC层模块和HF PHY层模块，控制器可对该HF模块进行控制。
下述结合多个实例对本申请实施例提供的通信方法进行举例说明。
图4为本申请实施例提供的一种通信方法的流程图。如图4所示，该通信方法可包括如下：
S401、发送节点在第一信道上向接收节点发送第一帧。
S402、发送节点在第二信道上向该接收节点发送至少一个第二帧，其中，每个该第二帧对应一个发送方向，每个第二帧的长度可小于预设帧长度。
对应的，在接收节点侧，该方法还包括：
S403、接收节点在第一信道上接收发送节点发送的该第一帧。
S404、接收节点在第二信道上接收发送节点发送的至少一个该第二帧。
具体地，若该通信方法应用于双模通信模式，则该第一信道的频率可小于该第二信道的频率。该第一信道可以为低频信道，该低频信道例如可以为2.4GHz频道、也可以为5.8GHz频道。当然，该低频信道还可以为其他低频的信道，上述仅为示例，本申请不对此进行限制。
该第二信道可以为高频信道，该高频信道例如可以为毫米波信道，如60GHz信道。当然，该高频信道还可以为其他频率的信道，上述仅为示例，本申请不对此进行限制。该第二信道的带宽可大于或等于预设信道带宽，该预设信道带宽可以为高频信道下的单信道带宽。举例来说，该第二信道的带宽可以为高频信道下的单信道带宽，也可以为整数倍如2 倍的高频信道下的单信道带宽。
若该通信方法适用于单模通信模式，则该第一信道和该第二信道分别为两个不同的高频信道。
若该第一信道和该第二信道均为高频信道，则在上述S401中发送节点可采用准全向发送方式向该接收节点发送该第一帧，在上述S402中发送节点可采用定向发送方式向该接收节点发送至少一个该第二帧；在上述S403中接收节点可采用准全向接收方式接收该发送节点发送的该第一帧，在上述S404中接收节点可采用定向接收方式接收发送节点发送至少一个该第二帧。
因此，无论对于双模通信模式，还是对于单模通信模式，该第二信道均可以为高频信道。
第二信道上发送的每个第二帧可对应一个发送方向，该发送方向可以为发送扇区或发送波束对应的发送方向。至少一个第二帧中，不同第二帧可对应不同的发送方向。因此，该至少一个第二帧可用于进行BF训练。接收节点在接收到至少一个该第二帧后，便可根据至少一个第二帧对发送节点的发送方向进行训练，以确定该发送节点的最佳发送方向，实现基于发送方向的BF训练。
其中，该预设帧长度可以为传统的帧长度，即现有通信标准中该第二信道上的帧长度。也就是说，该预设帧长度可以为在第一信道做分担协作之前，发送节点在第二信道每个方向上发送的帧的长度。
可选的，如上所示的第一帧可包括：该第二信道上的部分待传输信息，该第二帧这包括：该第二信道上的剩余待传输信息。
该第一帧中所包括的该第二信道上的部分待传输信息，以及，该第二帧中所包括的该第二信道上的剩余待传输信息，可构成该第二信道上完整的待传输信息，该完整的待传输信息可以为传统通信标准中，该第二信道上对应一个发送方向的帧中所包括的待传输信息。
可选的，该第一帧可包括：该第一信道上的待传输信息和/或该第二信道上的待传输信息。
也就是说，该第一帧可仅包括该第一信道上的待传输信息，也可仅包括该第二信道上的待传输信息，还可以既包括该第一信道上的待传输信息，也包括该第二信道上的待传输信息。其中，该第一帧中所包括的第二信道的待传输信息可为该第二信道上完整的待传输信息，也可以为该第二信道上的部分待传输信息。该第二信道上的部分待传输信息可以为该完整的待传输信息中的一部分信息。该完整的待传输信息可以为传统通信标准中，该第二信道上对应一个发送方向的帧中所包括的待传输信息。
若该第一帧中包括该第二信道上的待传输信息，则该第二帧中可不包括：该第二信道上的待传输信息。
也就是说，该通信方法中，可将该第二信道上的待传输信息，携带在第一帧中，在第一信道上发送至接收节点，降低了每个第二帧所包括的信息量，从而缩短了每个第二帧的长度。
举例来说，以双模通信模式为例，该第一信道为低频信道，第二信道为高频信道，该第一帧为信标帧，即低频信标帧。则该低频信标帧包括：802.11ad和/或802.11ay标准中高频信道上的待传输的信标帧所包括的信息；或者，该低频信标帧包括：802.11n和/或802.11ac 和/或802.11ax标准中低频信道上的待传输的信标帧所包括的信息，及802.11ad和/或802.11ay标准中高频信道上的待传输的信标帧所包括的信息。
可选的，传统的传输帧如数据帧或信令帧中，通常可包括：物理包头、MAC包头及负荷部分。本申请实施例所涉及的该第二帧可不包括：MAC包头和/或负荷部分，即该第二帧可包括：物理包头，或者包括物理包头和MAC包头，或者包括物理包头和负荷部分。因而，可使得每个第二帧的长度可小于预设帧长度。
需要说明的是，上述S401与上述S402可同时执行，也可先后执行，本申请不对此进行限制。也就是说，该发送节点可以在发送完该第一帧后，在该第二信道上向该接收节点发送至少一个第二帧。该发送节点也可先在该第二信道上向该接收节点发送至少一个该第二帧，继而在该第二帧发送完后，在该第一信道上向接收节点发送该第一帧。该发送节点还可以同时在该第一信道上发送第一帧，在第二信道上发送至少一个该第二帧。
上述S403与上述S404可同时执行，也可先后执行，本申请不对此进行限制。也就是说，该接收节点可以在接收完该第一帧后，在该第二信道上接收该发送节点发送的至少一个第二帧。该接收节点也可先在该第二信道上接收该发送节点发送的至少一个该第二帧，继而在该第二帧接收完后，在该第一信道上接收发送节点发送的该第一帧。该接收节点还可以同时在该第一信道上接收第一帧，在第二信道上接收至少一个该第二帧。
本申请实施例提供的通信方法，可通过发送节点在第一信道上向接收节点发送第一帧，在第二信道上向该接收节点发送至少一个第二帧，每个该第二帧对应一个发送方向，每个第二帧的长度可小于预设帧长度。该通信方法中，采用不同频率的信道进行协作通信向接收节点发送信息，在频率较高的第二信道上发送至少一个对应一个发送方向的第二帧，在频率较低的第一信道上发送第一帧，由于第一信道的分担协作，第二信道上传输的第二帧的长度小于预设帧长度，因而能降低第二信道上进行波束赋形训练时长，能提高网络的整体通信效率和吞吐量。
并且，该通信方法中，该第一信道的频率较低，信号的衰减较小，路径损耗较小，因此将该第二信道上的待传输信息携带在该第一信道上发送的该第一帧中，可有效提高信息传输的鲁棒性，提高网络性能。
可选的，由于该通信方法中，发送节点需在第一信道上发送第一帧，因而在发送该第一帧之前，该发送节点需先对该第一信道进行空闲信道评估(Clear Channel Assessment，CCA)以确定该第一信道是否空闲(Clear)，若该第一信道空闲，则在该第一信道上发送该第一帧。
由于该发送节点还在该第二信道上发送至少一个第二帧，该发送节点还需先对该第二信道进行CCA以确定该第二信道是否空闲，若该第二信道空闲，则在该第二信道上发送至少一个第二帧。
可选的，该第一帧中可包括：至少一个该第二帧对应的发送方向的标识。
可选的，每个第二帧中也可包括：该每个第二帧对应的发送方向的标识。
上述，每个第二帧对应的发送方向的标识可包括如下至少一个：每个第二帧对应的发送天线的标识、发送扇区的标识、发射波束的标识及倒计时信息等。
该通信方法中可在该第一帧中携带至少一个第二帧对应的发送方向的标识，并在该第一信道上发送至接收节点，以向接收节点枚举发送方向的标识，继而使得接收节点进行波 束赋形训练。
可选的，如上所示的方法中S402中发送节点在第二信道上向该接收节点发送至少一个第二帧可以包括：
距离该第一帧发送结束后的预设时间间隔后，该发送节点在该第二信道上向该接收节点发送至少一个该第二帧。
对于接收节点，至少一个该第二帧均为该发送节点在距离该第一帧发送结束后的预设时间间隔后所发送的。
具体地，该预设时间间隔可以为预设帧间间隔(X InterFrame Space，XIFS)，如短帧间间隔(Short InterFrame Space，SIFS)。当然，该预设时间间隔还可以为其他时间间隔，如大于SIFS的其他时间间隔。该预设时间间隔还可以为接收到的信令所指示的时间间隔。
该发送节点在距离该第一帧发送结束后的预设时间间隔后，发送至少一个第二帧，可使得接收节点准确识别该第二信道上发送的第二帧。
可选的，在如上任一所述的方法的基础上，该通信方法还可包括：
该发送节点在该第一信道上向该接收节点发送所述第一帧的同时，该发送节点还在该第二信道上向该接收节点发送第三帧；其中，该第三帧包括：一个第一帧、一个该第二帧，或者，一个该第二帧和训练序列(TRN)。
对于接收节点，在如上所示的S404中接收节点在第二信道上接收发送节点发送的至少一个该第二帧之前，该方法还可包括：
该接收节点在该第一信道上接收该发送节点发送的第三帧；该第三帧为该发送节点在该第一信道上向该接收节点发送该第一帧的同时所发送的。
具体地，该发送节点可在确定该第一信道与该第二信道均空闲的情况下，在第一信道上向该接收节点发送该第一帧，同时，还在该第二信道上向该接收节点发送该第三帧，如此，便可使得占用该第一信道和该第二信道，从而避免该第一信道和该第二信道被其他所抢占，从而发生冲突。
该第三帧的帧长度可等于该第一帧的时间长度。
在一种实现方式中，该第三帧例如可包括：该第二帧和填充信息，该填充信息的长度可以根据该第一帧的帧长度与该第二帧的帧长度的差值确定。
该填充信息可以为物理填充(PHY padding)信息，也可以为MAC填充信息如帧结束填充(End Of Frame padding，EOF padding)信息。
在另一种实现方式中，该第三帧例如可包括：该第二帧和训练序列。该训练序列的长度可以根据该第一帧的帧长度与该第二帧的帧长度的差值确定。
在一些其他实现方式中，该第三帧的帧长度也可不等于该第一帧的时间长度，如大于或小于该第一帧的时间长度。本申请不对此进行限制。
在另一些其他的实现方式中，该第三帧中也可不包括该第二帧，其该第三帧的类型与该第一帧的类型相同。举例来说，若该第一帧为信标帧，则该第三帧也可以为信标帧。
可选的，该第一帧中可包括：第一指示信息，该第一指示信息用于指示该发送节点在该第一信道和该第二信道上的通信能力。
对应的，该方法还可包括：
接收节点根据该第一指示信息，确定该发送节点在该第一信道和该第二信道上的通信 能力。
具体地，由于该第一信道和该第二信道分别为不同频率的信道，因此，在该第一信道和该第二信道上的通信能力也可称为双模通信能力，因而，该第一指示信息也可称为双模指示(Dual mode capability indication)信息。
该第一指示信息可位于该第一帧中的至少一个预设比特位中。该至少一个预设比特位可以位于该第一帧中现有通信标准的信息单元(Information Element，IE)中的预留比特、该第一帧中新增加的IE、第一帧中的可扩展IE等任一位置中。
该第一帧对应的通信标准不同，该第一指示信息在该第一帧的位置也不相同。
如下通过多个实例对第一指示信息在第一帧中的位置进行举例说明。
在一种示例中，该第一指示信息可位于该第一帧中的高吞吐能力单元(Very High Throughout Capability element)中的支持的高吞吐量-调制编码策略和空间流数量设置域(Supported Very High Throughout-Modulation and Coding Scheme and Number of Spatial Streams set field)中的预留比特中。
举例来说，图5为本申请实施例提供的一种高吞吐能力单元的结构示意图。图6为本申请实施例提供的一种高吞吐能力单元中支持的高吞吐量-调制编码策略和空间流数量设置域的结构示意图。
参见图5可知，高吞吐能力单元可包括：1字节的单元标识(Element ID)域、1字节的长度(Length)域、4字节的高吞吐量能力信息(Very High Throughout Capabilities info)域和8字节的支持的高吞吐量-调制编码策略和空间流数量设置域。
参见图6可知，该支持的高吞吐量-调制编码策略和空间流数量设置域可包括：16比特的接收高吞吐量-调制编码策略映射(Rx VHT–MCS Map)字段、13比特的接收最支持的长保护间隔数据速率(Rx Highest Supported Long Guard Iinterval Data Rate)字段、3比特的时空流数量和的最大值(maximum Number of Space-Time Streams.total)字段、16比特的发送高吞吐量-调制编码策略映射(Tx VHT–MCS Map)字段、13比特的发送最支持的长保护间隔数据速率(Tx Highest Supported Long Guard Iinterval Data Rate)字段、1比特的高吞吐量扩展空间流数量的可用带宽(VHT Extended NSS BW Capable)字段及2比特的预留字段。
该第一指示信息例如可位于图6中的预留字段中的至少一个比特位，也就是，比特(bit，B)62至比特63中的至少一个比特位。

参见图16可知，在BTI内，AP或PCP可作为发送节点在第一信道上向站点发送信标 帧；在发送该信标帧后的预设时间间隔后，在第二信道上向站点发送至少一个NDP帧。其中，若该第一信道为低频信道，该第二信道为高频信道，则该第一信道上发送的信标帧可称为LF信标帧，该第二信道上发送的每个NDP帧均可称为HF NDP帧。该第二信道上发送的每个NDP帧可对应一个发送方向。该第一信道上发送的信标帧可包括：所有NDP帧对应的发送方向的标识。

如下结合实例对NDP帧进行简要说明。图18为本申请实施例提供的通信方法中DMG NDP帧的结构示意图；图19为本申请实施例提供的通信方法中EDMG NDP帧的结构示意图；图20为本申请实施例提供的通信方法中FG60 NDP帧的结构示意图。
如图18所示，该DMG NDP帧可包括：短训练域(Short Training Field，STF域、信道估计域(Channel Estimation Field，CEF)及头块(Header Block)域。若该第二信道上发送的NDP帧为DMG NDP帧，则NDP帧中携带的信息，如COWN信息、天线标识和扇区标识等信息，例如可位于DMG NDP帧中的头块域中。

当然，该COWN信息、天线标识和扇区标识等信息还可以是位于第二信道上的其他信令，如控制尾部(control trailor)信令、或者第二信道上的其他帧如短信标帧中。
可选的，若该通信方法应用在WLAN系统中，可在扇区扫描阶段内，该扇区扫描阶段可位于关联波束赋形训练(Association BeamForming Training，A-BFT)期间或者数据传输间隔(Data Transfer Interval，DTI)内，该第一帧可以包括扇区扫描(Sector SWeep，SSW)帧或SSSW帧，该第二帧包括NDP帧或仅包括物理层包头的帧。
如下在A-BFT期间内，以第一帧为SSW帧，第二帧为NDP帧为例进行说明。图21、图22和图23是以A-BFT期间为例进行说明。图21为本申请实施例提供的一种通信方法中A-BFT内第一信道和第二信道上的一种帧传输示意图。图22为本申请实施例提供的一种通信方法中A-BFT内第一信道和第二信道上的另一种帧传输示意图。其中，该第一信道可以为低频信道，该第二信道可以为高频信道。若该通信方法中，该第一信道为低频信道，第二信道为高频信道，则图21和图22所示的A-BFT便可称为具有低频信道辅助的A-BFT。需要说明的是，图21和图22中所示的第一信道和第二信道也可分别为两个不同的高频信道。
参见图21可知，在A-BFT内，站点可作为发送节点在第一信道上向AP或PCP发送SSW帧；在发送该SSW帧后的预设时间间隔后，在第二信道上向AP或PCP发送至少一个NDP帧。其中，若该第一信道为低频信道，该第二信道为高频信道，则该第一信道上发送的SSW帧可称为LF SSW帧，该第二信道上发送的每个NDP帧均可称为HF NDP帧。该第二信道上发送的每个NDP帧可对应一个发送方向。该第二信道上发送的SSW帧可包括：所有NDP帧对应的发送方向的标识。
参见图22可知，在A-BFT内，站点可作为发送节点在第一信道上向AP或PCP发送SSW帧，同时，该站点也在第二信道上发送SSW帧；在第一信道上发送完SSW帧后的预设时间间隔后，在第二信道上还向AP或PCP发送至少一个NDP帧。其中，若该第一信道为低频信道，该第二信道为高频信道，则该第一信道上发送的SSW帧可称为LF SSW帧， 该第二信道上发送的SSW帧可称为HF SSW帧，该第二信道上发送的每个NDP帧均可称为HF NDP帧。该第一信道上的SSW帧的长度可等于该第二信道上的SSW帧的长度。当然，该第一信道上的SSW帧的长度也可不等于该第二信道上的SSW帧的长度，上述仅为示例说明，本发明不对此进行限制。
该第二信道上发送的每个NDP帧可对应一个发送方向。每个NDP帧包括该每个NDP帧对应的发送方向的标识，该每个NDP帧对应的发送方向的标识如下至少一种信息：COWN)信息、天线标识和扇区标识等。该第一信道上发送的SSW帧可包括：部分或所有NDP帧对应的发送方向的标识。
图22中第二信道上发送的SSW帧还可替换为NDP帧和训练序列，该训练训练也可对应一个或多个发送和/或接收方向，增加了扇区扫描的方向，节约扫描时间。
上述图21和图22中第一信道上发送的SSW帧中还可包括：第一指示信息，以指示该站点在第一信道和该第二信道上的通信能力。
上述图21和图22中第一信道上发送的SSW帧还中可包括：第二指示信息，以指示当前传输期间内，该SSW帧之后第二信道上是否发送有NDP帧。
上述图21和图22中第一信道上发送的SSW帧中还可包括：第三指示信息，以指示当前传输期间内第二信道上第一个NDP帧的开始发送时间，或者，该开始发送时间与预设时间的相对时间间隔。
上述图21和图22中第一信道上发送的SSW帧中还可包括：第四指示信息，以指示当前传输期间之后的传输期间内，是否在第一信道上发送SSW帧，在第二信道上发送至少一个NDP帧。
在WLAN系统中的A-BFT期间内，并非所有的站点需进行扇区扫描，也就是说，存在一些站点需在A-BFT期间内进行扇区扫描，而另一部分站点无需进行扇区扫描。因此，在A-BFT期间内，不同的站点可选择不同的信道进行通信，如需进行扇区扫描的站点采用第二信道进行通信，而无需进行扇区扫描的站点采用第一信道进行通信，如此可有效减少A-BFT期间内的冲突。
图23为本申请实施例提供的一种通信方法中A-BFT内第一信道和第二信道上的又一种帧传输示意图。
如图23所示，在A-BFT期间内，若站点1需进行扇区扫描，则站点1可在第二信道上向AP或PCP发送SSW帧，在发送完SSW帧后的预设时间间隔后，还在第二信道上还向AP或PCP发送至少一个NDP帧。若站点2无需进行扇区扫描，则站点2可在第一信道上向AP或PCP发送SSW帧即可。
在执行该图23所示的通信方法之前，AP或PCP可向站点1和站点2发送信标帧或通告帧(Annocement Frame)，信标帧或通告帧中携带有信道传输指示。该站点1可根据信道传输指示，确定该站点1在A-BFT期间内支持第二道传输，并确定在A-BFT期间内第二信道上的时隙个数；站点2可基于该信道传输指示，确定该站点2在A-BFT期间内支持第一信道传输，并确定在A-BFT期间内第一信道上的时隙个数。该信道传输指示可位于信标帧或通告帧中的预留字段中、新增IE或者可扩展IE等位置中。其中，AP或PCP可在第二信道上发送该信标帧或通告帧。
对于站点2在接收到该信标帧或通告帧后，在A-BFT期间内还可在第一信道向AP或 PCP返回信标传输期间对应的反馈(BTI Feedback)帧。在A-BFT期间内，AP或PCP可在第二信道或第一信道上向站点1返回对应的SSW反馈帧。
可选的，若该通信方法还可应用在WLAN系统中的通告传输期间(Announcement Transmission Interval，ATI)内。
在一种可能的实现方式中，在该ATI内，发送节点可在第一信道上向接收节点发送请求(request)帧，并接收该接收节点在第一信道上返回的响应(response)帧。也就是说，该ATI内的请求帧和响应帧可以仅在第一信道上，而无需在第二信道上进行传输，即可去掉第二信道的ATI。
在另一种可能的实现方式中，在该ATI内，一些发送节点可在第一信道上向接收节点发送请求帧，并接收接收节点在第一信道上返回的响应帧。而对于另一些发送节点，可在第二信道上向接收节点发送请求帧，并接收接收节点在第二信道上返回的响应帧。也就是说，该ATI内的请求帧和响应帧可以在第一信道上，也可在第二信道上进行传输，可以进一步提高ATI内的通信效率，即同时发生请求帧和响应帧的个数增加了。

站点N-1在接收到响应帧N-1后，还可在第一信道上向AP或PCP返回确认帧；站点N在接收到响应帧N后，还可在第二信道上向AP或PCP返回确认帧。
可选的，本申请实施例还可提供一些WLAN系统的其他阶段的信道辅助的通信方法。在一种可选的实例中，AP或PCP可在第一信道上向站点发送控制帧(Control frame)或管理帧(management frame)，并接收站点在第二信道上返回的数据帧(Data frame)或扫描帧。其中，该控制帧或管理帧例如可以为触发帧(Trigger frame)、直连安全设置请求(DLS setup request)帧、直连安全设置响应(DLS setup response)、关联请求(Associate request)帧、关联响应(Associate response)帧、探测请求(probe request)帧等任一帧。该扫描帧例如可包括如上所示的NDP帧、SSSW帧、非服务质量帧、短信标帧、仅包括物理层包头 的帧或其他帧。该第一信道可以为低频信道，第二信道可以为高频信道。该第一信道和该第二信道也可分别为不同的高频信道。

若该第一信道为低频信道，第二信道为高频信道，如不同站点位于不同的方向，那么采用上述通信方式在第一信道上发送控制帧或管理帧，便无需在第二信道上发送多个控制帧或管理帧，减小了AP或PCP发送控制帧或管理帧的个数。
需要说明的是，该控制帧或管理帧可包括：一个指示信息，用以指示所有站点返回数据帧或扫描帧对应的信道为第一信道还是第二信道。该一个指示信息可位于该控制帧或管理帧中公共部分(common part)中的至少一个比特位。

若该第一信道为低频信道，第二信道为高频信道，如不同发送节点或接收节点位于不同的方向，那么采用上述通信方式在第一信道与接收节点传输请求帧或响应帧，便无需在第二信道上传输多个请求帧或多个响应帧，减小了发送节点与接收节点间传输的请求帧或响应帧的个数。
需要说明的是，该响应帧可包括：一个指示信息，用以指示所有发送节点返回数据帧或扫描帧对应的信道为第一信道还是第二信道。该一个指示信息可位于该响应帧中公共部分中的至少一个比特位。
该响应帧还可包括：另一个指示信息，用以指示每个发送节点返回数据帧或扫描帧对应的信道为第一信道还是第二信道。该另一个指示信息可位于该控制帧或管理帧中每个发送节点对应的用户专用部分中的至少一个比特位。
