如今超高可靠性(Ultra High Reliablity，UHR)技术的不断发展对系统吞吐量以及传输时延提出了更高的要求。为了提高系统吐吞量以及降低传输时延，当主信道繁忙时，通信设备可切换至次信道进行通信，从而提升系统的吞吐量，降低传输时延。
在主信道繁忙的情况下，通信双方需要切换至次信道进行信道侦听再进行数据交互。现有的切换至次信道进行信道侦听分为两种方式，一是顺序侦听，二是同时侦听进行侦听。但是，某些次信道也为某些基本服务集(Basic Service Set，BSS)的主信道，那么次信道的与该BSS其也会形成重叠基本服务集(Overlapping Basic Service Set，OBSS)，为了通信双方能够更加快速的进行传输以便减小时延，则需机制辅助通信双方能够快速的接入到次信道。但是现有机制下只定义了BSS Load(负载)机制。
例如，BSS Load element元素的格式如下表所示：
其中，Element ID字段和Length字段分别指示元素ID和长度，Station Count字段指示当前与BSS关联的STA的总数量，Channel Utilization字段指示主信道利用率，Available Admission Capacity字段用于指示可用的接入容量。
例如，Extended BSS Load element元素的格式如下表所示：
其中，Element ID字段和Length字段分别指示元素ID和长度，MU-MIMO Capable STA Count字段指示当前与BSS关联的STA的总数，Spatial Stream Underutilization字段指示未充分利用的空间域的时间百分比，Observable Secondary 20MHz Utilization字段指示了20MHz次信道的可观察负载，Observable Secondary 40MHz Utilization字段指示了40MHz次信道的可观察负载，Observable Secondary 80MHz Utilization字段指示了80MHz次信道的可观察负载。
例如，HE BSS Load element元素的格式如下表所示：
其中，Element ID字段和Length字段分别指示元素ID和长度，Element ID Extension字段用于指示元素扩展信息，HE STA Count字段指示当前与BSS关联的STA的总数量，Utilization字段指示AP与HE STA之间传输繁忙的时间，Frequency Underutilization字段指示未充分利用频率域资源的时间百分比，Spatial Stream Underutilization字段指示未充分利用的空间域的时间百分比。
上述BSS Load机制并不能满足所有的通信场景，也不能满足快速切换次信道的场景需求，因此需要重新对次信道的负载信息作出指示。
为解决上述问题，下面将进一步结合附图对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，并不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
图1是根据本公开实施例示出的通信系统的架构示意图。
如图1所示，通信系统100包括AP101和第一STA102。
其中，AP101可以是独立的AP或者是AP MLD的附属AP，第一STA102可以是独立的STA或者是Non-AP MLD的附属STA，在此不做限制。
其中，AP101和第一STA相关联。
在一些实施例中，AP101和第一STA102可以是带有无线保真芯片的终端设备或者网络设备。
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。

在一些实施例中，AP可以通过广播方式向所有关联STA发送第一无线帧。
在此情况下，第一无线帧用于指示AP与每个关联STA协商的、用于进行信道侦听的至少一个第一次信道的负载信息。
作为一示例，AP在与关联的所有STA进行次信道协商之后，可通过广播的方式向所有关联STA发送第一无线帧。第一无线帧用于指示与所有STA协商的所有用于进行信道侦听的次信道的负载信息，或者用于指示与所有STA协商的所有用于进行信道侦听的次信道中，除每个关联STA的工作信道以外的其他20MHz次信道的负载信息。

对于对应于20MHz的第一信息域而言，该第一信息域包括至少一个第一标识位，每个第一标识位与一个20MHz次信道相对应，每个第一标识位的标识值为第一值时，该第一标识位对应的20MHz次信道为一个第一次信道。
可选地，第一无线帧中包括的第一信息域可以分别为Secondary 20MHz bitmap信息域、Secondary 40MHz bitmap信息域以及Secondary 80MHz bitmap信息域。
例如，Secondary 20MHz bitmap信息域包括至少一个第一标识位，每个第一标识位的标识值为第一值时，相应的20MHz次信道为第一次信道。
在AP通过广播方式发送第一无线帧的情况下，第一无线帧可以通过至少一个第一信息域，指示与所有关联STA协商的用于进行信道侦听的所有次信道的负载信息，或者指示与所有关联STA协商的用于进行信道侦听的所有次信道中，除每个关联STA的工作信道以外的其他次信道(如20MHz次信道)的负载信息。
例如，第一无线帧包括Secondary 20MHz bitmap信息域、Secondary 40MHz bitmap信息域以及Secondary 80MHz bitmap信息域，通过Secondary 20MHz bitmap信息域指示与所有关联STA协商的用于进行信道侦听的所有20MHz次信道，通过Secondary 40MHz bitmap信息域指示与所有关联STA协商的用于进行信道侦听的所有40MHz次信道，通过Secondary 80MHz bitmap信息域指示与所有关联STA协商的用于进行信道侦听的所有80MHz次信道。
