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)和多连接站点设备(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1所示的通信系统100、或部分主体，但不限于此。图1所示的各主体是例示，通信系统可以包括图1中的全部或部分主体，也可以包括图1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。
图2是根据本公开实施例示出的信道控制方法的示意图之一。如图2所示，上述方法包括：
步骤201，第一设备感知主信道繁忙，感知次信道的信道状态；其中，所述信道状态包括空闲或繁忙。
在WLAN中，信道通常分为主信道和次信道(secondary channel或non-primary channel，或称为辅助信道、非主信道)；其中，次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。
作为示例，如图3所示，主信道例如图3中主20MHz信道；其中，次信道可以包含一个或多个子信道，例如图3中20MHz次信道和40MHz次信道。
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，则可切换到次信道通信，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次信道通信，或在T2时间段切换到40MHz次信道通信。
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。
此外，当在主信道进行通信(次信道繁忙)，当次信道空闲时，则可聚合主次信道进行通信提高系统的吞吐量；作为示例，如图4所示，在传输每个帧的过程中，可以聚合主信道和至少一个次信道传输。
本公开实施例中，第一设备感知(sensing，或侦听)主信道繁忙时，感知次信道的信道状态；其中，所述信道状态包括空闲或繁忙，后续根据次信道的空闲或繁忙状态，确定对主信道和/或其他次信道的随机退避窗口的处理操作。
步骤202，根据所述次信道的信道状态，确定对主信道和/或其他次信道的随机退避窗口的处理操作。
其中，在无线通信过程中，通信设备在传输数据之前，会检查各个信道是否处于空闲状态。若信道处于繁忙状态，通信设备会延迟接入并利用随机退避(random Backoff)算法来避免发生冲突， 等候至该信道再度空闲，由此形成接入延迟，该过程即随机退避过程。具体来讲，当WLAN网络中的某个WLAN设备监听到某个信道处于空闲状态，不立即发送数据，而是在经过一段时间后才开始发送数据。例如该WLAN设备可在竞争窗口(contending windows，CW)，即[0，CW]内随机选择一个值(可简称为随机数)，再接下来的分布式帧间距(DCF inter‐frame space，DIFS)时间检测到信道空闲后，开始倒数，即每经过1个时隙时间(slot time)的信道空闲时间(通常为9微秒(us))，随机数减1。在随机数减为0之前，若信道在某一个时隙时间的状态为繁忙，则暂停计数。之后，在信道从繁忙状态转为空闲状态时恢复计数，当随机数减为0的时候，开始在该信道上发送数据。CW可能的取值包括31、63、127、255、511、1023，对应的退避时间分别为279微秒、567微秒、1143微秒、2295微秒、4599微秒、9207微秒。其中，DCF指分布式协调功能(distributed coordination function，DCF)。
本公开实施例中，在第一设备感知次信道的信道状态之后，根据所述次信道的信道状态，确定对主信道和/或其他次信道的随机退避窗口的处理操作；处理操作例如维持该随机退避敞口的计数，或者生成新的随机退避数；根据所述次信道的信道状态，明确对主信道和/或其他次信道的随机退避窗口的处理操作，完善WLAN设备在主、次信道通信的机制，以满足UHR的传输需求。
在一些实施例中，所述第一设备感知主信道繁忙，包括：
所述第一设备感知主信道繁忙，执行随机退避操作，生成所述主信道的随机数以及网络分配矢量定时器(network allocation vector timer，NAV timer)。
其中，所述第一设备感知主信道繁忙，在主信道执行随机退避操作，生成主信道的随机数，随机数用于主信道执行随机退避过程。以及生成主信道在MAC层的NAV timer，一个设备可以维护一个或多个NAV timer，其中，NAV timer通过使用帧的MAC报头中的持续时间值来进行设置，NAV timer的值会随着时间推移不断减少。NAV不为零，表示主信道处于繁忙状态。NAV为零，表示主信道处于空闲状态。
在一些实施例中，所述次信道的增强分布式信道接入(enhanced distributed channel access，EDCA)接入参数与所述主信道的EDCA接入参数相同。
其中，这些次信道中的EDCA接入参数相同，且可与主信道中的EDCA接入参数一致，主信道中的EDCA即STA最近一次接收到AP广播beacon帧中携带的EDCA参数。
在一些实施例中，所述感知次信道的信道状态，包括：
所述次信道包括至少两个，对所述次信道进行顺序感知或同时感知。
其中，顺序感知即在每个次信道下分时进行感知；同时感知即在多个次信道下同时进行感知，在每个次信道中生成的随机退避数是相互独立的。
在一些实施例中，顺序感知的过程包括：
根据预设的次信道序号，依次对每个所述次信道进行分时感知；
且所述次信道下的NAV timer为0，随机退避数计数完成，再次感知所述次信道的信道状态。
其中，次信道序号可以站点设备与接入点设备之间预先协商的，也可以是根据信道带宽由大到小排序的，本公开实施例对此不做限定。
在对多个次信道下进行分时感知的过程，根据预设的次信道序号，依次对每个所述次信道进行分时感知；并且，在任一个次信道下，NAV timer剩余时间值为0，且随机退避数计数完成，再次感知该次信道的信道状态。

其中，N表示正整数；对于顺次感知的第N个次信道，如在该次信道下感知信道繁忙，则在该次信道下进行随机退避，生成随机数(即随机退避数)。并且在第一设备再次传输数据之前，同时在所述主信道，第N-1个次信道，第N个次信道中进行随机退避数计数，根据每个信道中NAV timer时长的设置，进行计数以及生成的随机数计数。
步骤503，若第N个次信道空闲，则在所述第N个次信道下进行传输数据，释放前N-1个次信道中的随机退避数，将前N-1个次信道的NAV timer置为0；以及维持所述主信道中的随机退避数，且维持所述主信道NAV timer计数。
其中，对于顺次感知的第N个次信道，如在该次信道下感知信道空闲，则在该次信道下进行数据的传输；释放在前N-1个次信道中的随机数，且将前N-1个次信道的NAV timer置为0；同时维持主信道中的随机数，且将主信道NAV timer维持计数。
