图1是根据本公开实施例示出的通信方法的示意图之一。FIG. 1 is a schematic diagram of a communication method according to an embodiment of the present disclosure.

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。As shown in Figure 1, in WLAN, channels are usually divided into primary channels and secondary channels (or non-primary channels, or called secondary channels, non-primary channels); the primary channel is, for example, the main 20 MHz channel in Figure 1; wherein, the secondary channel may include one or more sub-channels, such as the 20 MHz secondary channel and the 40 MHz secondary channel in Figure 1.

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。During the channel contention process, if the main channel is in the OBSS busy state (OBSS interference), as shown in the T1 time period and the T2 time period in the figure, for example, it is occupied by other devices in the same OBSS as the WLAN, and other devices send physical layer protocol data units (PPDU) on the main channel, then the main channel is in the OBSS busy state. If the main channel is in the OBSS busy state, in order to make full use of the channel resources, it can be switched to the auxiliary channel communication to improve the communication system throughput and maximize the channel resource utilization. For example, switch to the 20MHz auxiliary channel communication in the T1 time period, or switch to the 40MHz auxiliary channel communication in the T2 time period.

若主信道处于空闲状态，如图中T3时间段所示，则AP与STA之间可以互相发送数据或其他信息。If the primary channel is in an idle state, as shown in the T3 time period in the figure, the AP and the STA can send data or other information to each other.

Optionally, the site device 101 may support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, 802.11bn, and support the next generation 802.11 protocol, but is not limited thereto.

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。In some embodiments, the access point device 102 can be an access point for a mobile terminal to enter a wired network. The AP is equivalent to a bridge connecting a wired network and a wireless network. Its main function is to connect various wireless network clients together and then connect the wireless network to the Ethernet. Specifically, the AP can be a terminal device or a network device with a wireless fidelity chip. Optionally, the AP can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b and 802.11a, 802.11bf, 802.11bn, and support the next generation 802.11 protocol, but is not limited to this.

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。Optionally, in the disclosed embodiment, AP and STA may be devices supporting multiple connections, for example, may be respectively represented as a multi-connection access point device (Access Point Multi-Link Device, AP MLD) and a multi-connection site device (Non-Access Point Multi-Link Device, Non-AP MLD); AP MLD may represent an access point supporting multi-connection communication functions, and non-AP MLD may represent a site supporting multi-connection communication functions.

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。It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. A person skilled in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

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。The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG2, or part of the subject, but are not limited thereto. The subjects shown in FIG2 are examples. The communication system may include all or part of the subjects in FIG2, or may include other subjects other than FIG2. The number and form of the subjects are arbitrary. The subjects may be physical or virtual. The connection relationship between the subjects is an example. The entities may be connected or disconnected, and the connection may be in any manner, direct or indirect, wired or wireless.

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。The embodiments of the present disclosure can be applied to a wireless local area network (WLAN), such as a local area network using the 802.11 series of protocols. In a WLAN, a basic service set (BSS) is a basic component of a WLAN. A BSS network is composed of station devices with some association within a specific coverage area. One case of association is that stations communicate directly with each other in an ad hoc network, which is called an independent BSS (IBSS). Another more common case is that there is only one central station in the BSS network that is dedicated to managing the BSS, which is called an access point device, and all other STAs in the network are associated with it. Other stations in the BSS network that are not central stations are called terminals, also called non-AP STAs, and terminals and non-AP STAs are collectively referred to as STAs. When describing STAs, there is no need to distinguish between APs and non-AP STAs. In the same BSS network, due to distance, transmission power, etc., a STA cannot detect other STAs that are far away from it, and the two are hidden nodes of each other.

图3是根据本公开实施例示出的通信方法的示意图之一，如图3所示，上述方法包括：FIG. 3 is one of schematic diagrams of a communication method according to an embodiment of the present disclosure. As shown in FIG. 3 , the method includes:

步骤301，接入点设备在主信道发送第一无线帧；其中，所述第一无线帧请求站点设备发送数据帧或缓存信息。Step 301: The access point device sends a first wireless frame on a primary channel; wherein the first wireless frame requests the site device to send a data frame or cache information.

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。In WLAN, channels are usually divided into primary channels and secondary channels (or non-primary channels); among them, secondary channels can contain one or more sub-channels. For example, if 20MHz is used as the basic bandwidth unit for division, when the channel bandwidth is 20MHz, there is only one primary channel with a bandwidth of 20MHz; when the channel bandwidth is greater than 20MHz, a channel with a bandwidth of 20MHz is included as the primary channel, and the remaining one or more 20MHz channels are secondary channels. The primary 20MHz channel is the common channel of operation for stations that are members of the basic service set. Stations in the BSS can compete for channels on the primary 20MHz channel to seize channel resources.

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。In the process of channel competition on the channel, if the main channel is in the OBSS busy state, for example, it is occupied by other devices in the same OBSS as the access point device 102, and other devices send physical layer protocol data units (PPDU) on the main channel, then the main channel is in the OBSS busy state. If the main channel is in the OBSS busy state, in order to fully utilize the channel resources, it can switch to the auxiliary channel to communicate with the site device 101, schedule the site device 101 to the auxiliary channel, and send and receive data with the site device 101, so as to improve the communication system throughput and maximize the utilization of channel resources.

本公开实施例中，接入点设备102在主信道感知信道是否繁忙；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，例如通过能量检测(energy detection，ED)机制实现。接入点设备102感知主信道空闲，则在主信道发送第一无线帧，通过所述第一无线帧请求站点设备发送数据帧或缓存信息。In the disclosed embodiment, the access point device 102 senses whether the main channel is busy. Generally, each station device on the network needs to listen to whether there is other data being transmitted on the channel before sending data, for example, through an energy detection (ED) mechanism. When the access point device 102 senses that the main channel is idle, it sends a first wireless frame on the main channel, and requests the station device to send a data frame or cache information through the first wireless frame.

可选地，第一无线帧可以包括请求发送(request to send，RTS)帧或缓冲区状态报告轮询(buffer status report poll，BSRP)控制帧。而在接入点设备102发送RTS帧或BSRP控制帧时，站点设备101可能无法接收到第一无线帧，例如由于隐藏节点的存在，其他隐藏节点与站点设备101通信干扰了站点设备101接收第一无线帧。Optionally, the first radio frame may include a request to send (RTS) frame or a buffer status report poll (BSRP) control frame. When the access point device 102 sends the RTS frame or the BSRP control frame, the site device 101 may not be able to receive the first radio frame, for example, due to the existence of hidden nodes, other hidden nodes communicating with the site device 101 interfere with the site device 101 receiving the first radio frame.

第一预设帧间隔包括接收第一无线帧的响应帧的预设时间，例如，预设时间可以预先设定为n个短帧间隔(short inter frame space，SIFS)，n为正整数；在第一预设帧间隔内，若接收到站点设备反馈的所述响应帧，则执行步骤303；否则，执行步骤302。The first preset frame interval includes a preset time for receiving a response frame of the first wireless frame. For example, the preset time can be pre-set to n short frame intervals (short inter frame space, SIFS), where n is a positive integer. Within the first preset frame interval, if the response frame fed back by the site device is received, execute step 303; otherwise, execute step 302.

步骤302，在第一预设帧间隔内未接收到所述站点设备响应的第二无线帧，不重复发送所述第一无线帧。Step 302: If no second radio frame in response to the site device is received within a first preset frame interval, the first radio frame is not sent repeatedly.

其中，在第一预设帧间隔内若未接收到所述站点设备响应的第二无线帧，即站点设备在预设的时间内未向接入点设备102发送用于响应第一无线帧的第二无线帧，则站点设备101可能没有收到所述第一无线帧，此时，接入点设备102不重复发送所述第一无线帧，避免连续重复发送第一无线帧造成信令资源的浪费。Among them, if the second radio frame responded by the site device is not received within the first preset frame interval, that is, the site device does not send the second radio frame used to respond to the first radio frame to the access point device 102 within the preset time, then the site device 101 may not receive the first radio frame. At this time, the access point device 102 does not repeatedly send the first radio frame to avoid wasting signaling resources due to continuous repeated sending of the first radio frame.

可选地，第二无线帧可以是清除发送(clear to send，CTS)帧或缓冲区状态报告(buffer status report，BSR)帧。Optionally, the second wireless frame may be a clear to send (CTS) frame or a buffer status report (BSR) frame.

步骤304，在辅助信道通过backoff机制，向所述站点设备发送第三无线帧；其中，所述第三无线帧用于触发所述站点设备切换到辅助信道与所述接入点设备通信。Step 304: Send a third radio frame to the site device through a backoff mechanism on the auxiliary channel; wherein the third radio frame is used to trigger the site device to switch to the auxiliary channel to communicate with the access point device.

其中，若接入点设备102与站点设备101预先协商了当主信道感知到繁忙时，需切换至辅信道进行通信，则在步骤302之后，接入点设备102与站点设备101可以切换至辅信道通信。接入点设备102在辅助信道通过backoff机制，向所述站点设备发送第三无线帧，第三无线帧例如RTS帧或缓冲区状态报告轮询(buffer status report poll，BSRP)帧，通过第三无线帧触发至辅信道通信。If the access point device 102 and the station device 101 have agreed in advance that when the primary channel senses busy, they need to switch to the secondary channel for communication, then after step 302, the access point device 102 and the station device 101 can switch to the secondary channel for communication. The access point device 102 sends a third wireless frame to the station device through the backoff mechanism on the secondary channel, such as an RTS frame or a buffered frame. The buffer status report poll (BSRP) frame triggers the communication to the auxiliary channel through the third radio frame.

在一些实施例中，所述第一无线帧的持续时间包括：两个短帧间隔、所述第二无线帧的发送时长、所述第一无线帧的发送时长与BA消息帧的时间长度之和；In some embodiments, the duration of the first radio frame includes: the sum of two short frame intervals, the transmission duration of the second radio frame, the transmission duration of the first radio frame, and the time length of a BA message frame;

其中，第一无线帧的持续时间(duration)字段设置为下述各元素的时长之和：The duration field of the first radio frame is set to the sum of the durations of the following elements:

2×SIFS+所述第二无线帧的发送时长(例如CTS的发送时长)+所述第一无线帧的发送时长(例如RTS的发送时长)+确认消息帧(BA消息帧或ACK消息帧)的发送时长。2×SIFS+the sending duration of the second wireless frame (for example, the sending duration of CTS)+the sending duration of the first wireless frame (for example, the sending duration of RTS)+the sending duration of the confirmation message frame (BA message frame or ACK message frame).

以第一无线帧为RTS，第二无线帧为CTS，确认消息帧为BA为例，参见图4，第一无线帧的持续时间如图4所示，包括：2×SIFS+CTS的发送时长(或接收时长)+所述第一无线帧的发送时长+BA消息帧的发送时长(或接收时长)之和；其中，2×SIFS分别表示2个SIFS，即图4中S1和S2。Taking the first wireless frame as RTS, the second wireless frame as CTS, and the confirmation message frame as BA as an example, referring to Figure 4, the duration of the first wireless frame is shown in Figure 4, including: 2×SIFS+CTS sending duration (or receiving duration)+the sum of the sending duration of the first wireless frame+the sending duration (or receiving duration) of the BA message frame; wherein, 2×SIFS represents 2 SIFS respectively, namely S1 and S2 in Figure 4.

其中，在第一个SIFS(S1)之后，接入点设备102可能会接收到第二无线帧。After the first SIFS (S1), the access point device 102 may receive a second radio frame.

其中，BA消息帧为块确认(Block Ack，BA)消息帧。Among them, the BA message frame is a block confirmation (Block Ack, BA) message frame.

在一些实施例中，所述第三无线帧的持续时间包括：两个短帧间隔、所述第二无线帧的发送时长、所述第一无线帧的发送时长、BA消息帧或ACK消息帧的发送时长的时间长度之和。In some embodiments, the duration of the third wireless frame includes: the sum of two short frame intervals, the transmission duration of the second wireless frame, the transmission duration of the first wireless frame, and the transmission duration of a BA message frame or an ACK message frame.

其中，接入点设备102在辅助信道通过backoff机制，向所述站点设备发送第三无线帧。参见图5，第三无线帧的持续时间如图5所示，包括：2×SIFS+CTS的发送时长(或接收时长)+所述第一无线帧的发送时长+BA或ACK消息帧的发送时长(或接收时长)之和；其中，2×SIFS分别表示2个SIFS，即图5中S1和S2。The access point device 102 sends a third radio frame to the site device through a backoff mechanism in the auxiliary channel. Referring to FIG5 , the duration of the third radio frame is shown in FIG5 , including: the sum of 2×SIFS+CTS sending duration (or receiving duration)+the sending duration of the first radio frame+the sending duration (or receiving duration) of the BA or ACK message frame; wherein 2×SIFS represents 2 SIFS, namely S1 and S2 in FIG5 .

步骤303，接收所述第二无线帧；其中，所述第二无线帧的持续时间为所述第一无线帧的持续时间或主信道NAV的设置时长。Step 303: Receive the second radio frame; wherein the duration of the second radio frame is the duration of the first radio frame or the set duration of the primary channel NAV.

其中，若接入点设备102未感知到主信道繁忙，不设置网络分配矢量(network allocation vector，NAV)。而站点设备101感知到主信道繁忙，则需要设置NAV。由于在辅助信道的通信时长不超过主信道NAV的设置时长，则站点设备发送的所述第二无线帧的持续时间通常也不超过辅助信道的通信时长，选择第一无线帧的持续时间与所述主信道NAV设置时长中，较小的时间值作为第二无线帧的持续时间。If the access point device 102 does not sense that the main channel is busy, the network allocation vector (NAV) is not set. If the site device 101 senses that the main channel is busy, the NAV needs to be set. Since the communication duration of the auxiliary channel does not exceed the set duration of the main channel NAV, the duration of the second wireless frame sent by the site device usually does not exceed the communication duration of the auxiliary channel. The smaller time value between the duration of the first wireless frame and the set duration of the main channel NAV is selected as the duration of the second wireless frame.

在一些实施例中，所述第一无线帧的持续时间大于所述主信道NAV设置时长，所述第二无线帧的持续时间为所述主信道NAV设置时长；In some embodiments, the duration of the first radio frame is greater than the primary channel NAV setting duration, and the duration of the second radio frame is the primary channel NAV setting duration;

或or

其中，若所述第一无线帧的持续时间大于所述主信道NAV设置时长，则所述第二无线帧的持续时间为所述主信道NAV设置时长，使得第二无线帧的持续时间不会超过所述主信道NAV设置时长。If the duration of the first radio frame is greater than the duration set for the primary channel NAV, the duration of the second radio frame is the duration set for the primary channel NAV, so that the duration of the second radio frame does not exceed the duration set for the primary channel NAV.

若所述第一无线帧的持续时间小于或等于所述主信道NAV设置时长，则所述第二无线帧的持续时间为所述第一无线帧的持续时间，使得二者持续时间一致，且不会超过所述主信道NAV设置时长。If the duration of the first radio frame is less than or equal to the duration set for the primary channel NAV, the duration of the second radio frame is the duration of the first radio frame, so that the durations of the two are consistent and will not exceed the duration set for the primary channel NAV.

在一些实施例中，可参见图3所对应的说明书之前或之后记载的其他可选实现方式。In some embodiments, reference may be made to other optional implementations recorded before or after the description corresponding to FIG. 3 .

图6是根据本公开实施例示出的通信方法的示意图之二，如图6所示，上述方法包括：FIG. 6 is a second schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 6 , the method includes:

步骤601，站点设备101在主信道发送第四无线帧；其中，所述第四无线帧请求接入点设备102发送数据帧。Step 601 : The site device 101 sends a fourth radio frame on a primary channel; wherein the fourth radio frame requests the access point device 102 to send a data frame.

其中，站点设备101在主信道感知信道是否繁忙；通常情况下，网络上各个站点设备101在发送数据前都要侦听信道上有没有其他数据在传输，例如通过能量检测(energy detection，ED)机制实现。站点设备101感知主信道空闲，则在主信道发送第四无线帧，通过所述第四无线帧请求接入点设备102发送数据帧或缓存信息。 The site device 101 senses whether the main channel is busy. Usually, each site device 101 on the network needs to monitor whether there is other data being transmitted on the channel before sending data, for example, through an energy detection (ED) mechanism. If the site device 101 senses that the main channel is idle, it sends a fourth wireless frame on the main channel, and requests the access point device 102 to send a data frame or cache information through the fourth wireless frame.

可选地，第四无线帧可以包括请求发送(request to send，RTS)帧。而在站点设备101发送RTS帧时，接入点设备102可能无法接收到第四无线帧，例如由于隐藏节点的存在，其他隐藏节点与接入点设备102通信干扰了接入点设备102接收第四无线帧。Optionally, the fourth wireless frame may include a request to send (RTS) frame. When the site device 101 sends the RTS frame, the access point device 102 may not be able to receive the fourth wireless frame, for example, due to the presence of hidden nodes, other hidden nodes communicating with the access point device 102 interfere with the access point device 102 receiving the fourth wireless frame.

第二预设帧间隔包括接收第四无线帧的响应帧的预设时间，例如，预设时间可以预先设定为n个短帧间隔(short inter frame space，SIFS)，n为正整数；在第二预设帧间隔内，若接收到接入点设备102反馈的所述响应帧，则执行步骤603；否则，执行步骤602。The second preset frame interval includes a preset time for receiving a response frame of the fourth wireless frame. For example, the preset time can be pre-set to n short frame intervals (short inter frame space, SIFS), where n is a positive integer. Within the second preset frame interval, if the response frame fed back by the access point device 102 is received, step 603 is executed; otherwise, step 602 is executed.

步骤602，在第二预设帧间隔内未接收到所述接入点设备102响应的第五无线帧，不重复发送所述第四无线帧。Step 602: If the fifth radio frame responded by the access point device 102 is not received within the second preset frame interval, the fourth radio frame is not sent repeatedly.

其中，在第二预设帧间隔内若未接收到所述接入点设备102响应的第五无线帧，即接入点设备102在预设的时间内未向站点设备101发送用于响应第四无线帧的第五无线帧，则接入点设备102可能没有收到所述第四无线帧，此时，站点设备101不重复发送所述第四无线帧，避免连续重复发送第四无线帧造成信令资源的浪费。Among them, if the fifth radio frame responded by the access point device 102 is not received within the second preset frame interval, that is, the access point device 102 does not send the fifth radio frame used to respond to the fourth radio frame to the site device 101 within the preset time, then the access point device 102 may not receive the fourth radio frame. At this time, the site device 101 does not repeatedly send the fourth radio frame, so as to avoid wasting signaling resources caused by continuously and repeatedly sending the fourth radio frame.

可选地，第五无线帧可以是清除发送(clear to send，CTS)帧。Optionally, the fifth wireless frame may be a clear to send (CTS) frame.

步骤604，在辅助信道通过backoff机制，向所述接入点设备102发送第六无线帧；其中，所述第六无线帧用于触发所述接入点设备102切换到辅助信道与所述站点设备101通信。Step 604 : Send a sixth radio frame to the access point device 102 through a backoff mechanism on the auxiliary channel; wherein the sixth radio frame is used to trigger the access point device 102 to switch to the auxiliary channel to communicate with the site device 101 .

其中，若站点设备101与接入点设备102预先协商了当主信道感知到繁忙时，需切换至辅信道进行通信，则在步骤602之后，站点设备101与接入点设备102可以切换至辅信道通信。站点设备101在辅助信道通过backoff机制，向所述接入点设备102发送第六无线帧，第六无线帧例如RTS帧或缓冲区状态报告轮询(buffer status report poll，BSRP)帧，通过第六无线帧触发至辅信道通信。If the site device 101 and the access point device 102 have pre-negotiated that when the primary channel senses busy, it is necessary to switch to the secondary channel for communication, then after step 602, the site device 101 and the access point device 102 can switch to the secondary channel for communication. The site device 101 sends a sixth radio frame to the access point device 102 through a backoff mechanism on the secondary channel, and the sixth radio frame is, for example, an RTS frame or a buffer status report poll (BSRP) frame, and the communication on the secondary channel is triggered through the sixth radio frame.

在一些实施例中，所述第四无线帧的持续时间包括：两个短帧间隔、所述第五无线帧的发送时长、所述第四无线帧的发送时长与BA消息帧的时间长度之和；In some embodiments, the duration of the fourth radio frame includes: the sum of two short frame intervals, the transmission duration of the fifth radio frame, the transmission duration of the fourth radio frame and the time length of the BA message frame;

其中，第四无线帧的持续时间(duration)字段设置为下述各元素的时长之和：The duration field of the fourth radio frame is set to the sum of the durations of the following elements:

2×SIFS+所述第五无线帧的发送时长(例如CTS的发送时长)+所述第四无线帧的发送时长(例如RTS的发送时长)+确认消息帧(BA消息帧或ACK消息帧)的发送时长。2×SIFS+the sending duration of the fifth radio frame (for example, the sending duration of CTS)+the sending duration of the fourth radio frame (for example, the sending duration of RTS)+the sending duration of the confirmation message frame (BA message frame or ACK message frame).

以第四无线帧为RTS，第五无线帧为CTS，确认消息帧为BA为例，参见图4，第四无线帧的持续时间参考图4所示的第一无线帧，包括：2×SIFS+CTS的发送时长(或接收时长)+所述第四无线帧的发送时长+BA消息帧的发送时长(或接收时长)之和；其中，2×SIFS分别表示2个SIFS，即图4中S1和S2。Taking the fourth wireless frame as RTS, the fifth wireless frame as CTS, and the confirmation message frame as BA as an example, referring to Figure 4, the duration of the fourth wireless frame refers to the first wireless frame shown in Figure 4, including: 2×SIFS+CTS sending duration (or receiving duration)+the sum of the sending duration of the fourth wireless frame+the sending duration (or receiving duration) of the BA message frame; wherein, 2×SIFS represents 2 SIFS respectively, namely S1 and S2 in Figure 4.

其中，在第一个SIFS(S1)之后，站点设备101可能会接收到第五无线帧。After the first SIFS (S1), the station device 101 may receive the fifth radio frame.

在一些实施例中，所述第六无线帧的持续时间包括：两个短帧间隔、所述第五无线帧的发送时长、所述第四无线帧的发送时长、BA消息帧或ACK消息帧的发送时长的时间长度之和。In some embodiments, the duration of the sixth wireless frame includes: the sum of two short frame intervals, the transmission duration of the fifth wireless frame, the transmission duration of the fourth wireless frame, and the transmission duration of a BA message frame or an ACK message frame.

其中，站点设备101在辅助信道通过backoff机制，向所述接入点设备102发送第六无线帧。参见图5所示的第三无线帧，包括：2×SIFS+CTS的发送时长(或接收时长)+所述第四无线帧的发送时长+BA或ACK消息帧的发送时长(或接收时长)之和；其中，2×SIFS分别表示2个SIFS，即图5中S1和S2。The site device 101 sends the sixth radio frame to the access point device 102 through the backoff mechanism on the auxiliary channel. Referring to the third radio frame shown in FIG5 , it includes: 2×SIFS+the sum of the sending duration (or receiving duration) of CTS+the sending duration of the fourth radio frame+the sending duration (or receiving duration) of the BA or ACK message frame; wherein 2×SIFS represents 2 SIFS, namely S1 and S2 in FIG5 .

步骤603，接收所述第五无线帧；其中，所述第五无线帧的持续时间为所述第四无线帧的持续时间或主信道NAV的设置时长。Step 603: Receive the fifth radio frame; wherein the duration of the fifth radio frame is the duration of the fourth radio frame or the set duration of the primary channel NAV.

其中，若站点设备101未感知到主信道繁忙，不设置NAV。而接入点设备102感知到主信道繁忙，则需要设置NAV。由于在辅助信道的通信时长不超过主信道NAV的设置时长，则接入点设备102发送的所述第五无线帧的持续时间通常也不超过辅助信道的通信时长，选择第四无线帧的持续时间与所述主信道NAV设置时长中，较小的时间值作为第五无线帧的持续时间。If the site device 101 does not sense that the main channel is busy, the NAV is not set. If the access point device 102 senses that the main channel is busy, the NAV needs to be set. Since the communication duration of the auxiliary channel does not exceed the set duration of the main channel NAV, the duration of the fifth wireless frame sent by the access point device 102 usually does not exceed the communication duration of the auxiliary channel, and the smaller time value between the duration of the fourth wireless frame and the set duration of the main channel NAV is selected as the duration of the fifth wireless frame.

在一些实施例中，所述第四无线帧的持续时间大于所述主信道NAV设置时长，所述第五无线帧的持续时间为所述主信道NAV设置时长；In some embodiments, the duration of the fourth radio frame is greater than the primary channel NAV setting duration, and the duration of the fifth radio frame is the primary channel NAV setting duration;

或 or

其中，若所述第四无线帧的持续时间大于所述主信道NAV设置时长，则所述第五无线帧的持续时间为所述主信道NAV设置时长，使得第五无线帧的持续时间不会超过所述主信道NAV设置时长。If the duration of the fourth radio frame is greater than the duration set for the primary channel NAV, the duration of the fifth radio frame is the duration set for the primary channel NAV, so that the duration of the fifth radio frame does not exceed the duration set for the primary channel NAV.

若所述第四无线帧的持续时间小于或等于所述主信道NAV设置时长，则所述第五无线帧的持续时间为所述第四无线帧的持续时间，使得二者持续时间一致，且不会超过所述主信道NAV设置时长。If the duration of the fourth radio frame is less than or equal to the duration set for the primary channel NAV, the duration of the fifth radio frame is the duration of the fourth radio frame, so that the durations of the two are consistent and will not exceed the duration set for the primary channel NAV.
