具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
图1是本申请一示例性实施例示出的一种下行数据缓存指示方法的流程图，该实施例从AP侧进行描述，如图1所示，该下行数据缓存指示方法包括：
在步骤S101中，生成信标帧，该信标帧中包含下行数据缓存指示信息位，该下行数据缓存指示信息位用于指示信标帧是否缓存有下行数据。
其中，当该下行数据缓存指示信息位为第一预设值，例如为“1”时，指示该信标帧缓存有下行数据，当该下行数据缓存指示信息位为第二预设值，例如为“0”时，指示该信标帧未缓存有下行数据。
在该实施例中，可以根据待缓存下行数据的优先级，将苏醒周期所在信标帧中的 下行数据缓存指示信息位设置为缓存有下行数据。
例如，对于低优先级的下行数据，可以将苏醒周期所在信标帧中的下行数据缓存指示信息位设置为缓存有下行数据，即将下行数据缓存指示信息位和苏醒周期设置在同一信标帧中，同时站点获得在信标帧中的时间同步功能(time synchronization function，简称TSF)信息，以便与接入点保持时间上同步，这样复用了信标帧中的TSF和下行数据缓存指示信息位，有利于节省站点的电能。
在步骤S102中，在每个站点的侦听频段向对应站点发送信标帧，其中，该侦听频段为对应站点侦听获取下行数据的频段。
可选地，在执行步骤S102之前，该方法还可以包括：确定每个站点的侦听频段。
其中，确定每个站点的侦听频段可以包括：与每个站点建立关联，将建立关联时所在的频段确定为每个站点的侦听频段。
由于AP根据不同频段下的负载情况和在竞争期内发生冲突的情况来确定每个站点的监听频段，因此，所确定的监听频段可能与建立关联时所在的频段不同，在这种情况下，可以通过协商帧携带为每个站点确定的侦听频段，侦听频段用于侦听接入点广播带有下行数据缓存指示信息位的信标帧。其中，该协商帧也用于AP与每个站点之间协商每个站点的休眠周期。
在该实施例中，在确定好每个站点的侦听频段之后，在每个站点的侦听频段向对应站点发送信标帧，每个站点在对应的侦听频段侦听信标帧，对侦听到的信标帧进行解析，以获取下行数据。
上述实施例，通过在每个站点的侦听频段向对应站点发送包含下行数据缓存指示信息位的信标帧，从而解决了在多频段下AP如何发送beacon帧的问题。
图2是本申请一示例性实施例示出的一种下行数据获取方法的流程图，该实施例从站点侧进行描述，如图2所示，该方法包括：
在步骤S201中，在当前站点的侦听频段下侦听接入点发送的信标帧。
可选地，在执行步骤S201之前，该方法还可以包括：与接入点建立关联，将建立关联时所在的频段确定为当前站点的侦听频段。
由于AP根据不同频段下的负载情况和在竞争期内发生冲突的情况来确定每个站点的监听频段，因此，所确定的监听频段可能与建立关联时所在的频段不同，在这种情 况下，可以通过协商帧携带为每个站点确定的侦听频段。其中，该协商帧用于当前站点与AP之间协商当前站点的休眠周期。
在确定好当前站点的侦听频段之后，在该侦听频段下侦听接入点发送的信标帧。
在步骤S202中，若侦听到信标帧，则从信标帧中解析下行数据缓存指示信息位。
在步骤S203中，若下行数据缓存指示信息位指示信标帧缓存有下行数据，则在侦听频段的竞争期(contention period，简称CP)下向接入点发送省电(power saving，简称PS)轮询(Poll)帧，以获取下行数据。
上述实施例，通过在当前站点的侦听频段下侦听接入点发送的信标帧，并从侦听到的信标帧中解析下行数据缓存指示信息位，若下行数据缓存指示信息位指示信标帧缓存有下行数据，则在侦听频段的竞争期下向接入点发送省电轮询帧，以获取下行数据，从而解决了多频段下站点如何侦听信标帧来获取下行数据的问题。
图3是本申请一示例性实施例示出的一种下行数据获取方法的信令流程图，该实施例从AP和当前站点交互的角度进行描述，如图3所示，该方法包括：
在步骤S301中，当前站点与AP建立关联。
其中，每个站点均可以通过多种方式例如以下两种方式与AP建立关联：
方式11)AP在设定频段下广播信标帧，至少一个站点在接收到该广播信标帧后，向AP发送关联请求帧，AP根据该关联请求帧向对应站点返回关联响应帧，以实现与每个站点建立关联。
其中，设定频段可以为多个工作频段中的一个工作频段。
方式12)至少一个站点向AP发送探测请求帧，AP在接收到该探测请求帧之后，向对应站点返回探测响应帧，对应站点在接收探测响应帧之后，向AP发送关联请求帧，AP根据该关联请求帧向对应站点返回关联响应帧，以实现与每个站点建立关联。
在步骤S302中，AP为当前站点分配关联标识(Association Identifier，简称AID)，将建立关联时所在的频段确定为当前站点的侦听频段。
由于AP可能会在多个频段下发送beacon帧，一个AP在一个基本服务集(basis service set，简称BSS)中只能管理最多2007个站点，那么，对于同时能够在多个频段下进行通信的接入点来说，可以通过以下方式为每个站点分配AID：
方式21)针对所有的工作频段，按照建立关联的先后顺序为每个站点分配唯一的 关联标识。
例如，所有的工作频段为f1、f2和f3，站点1先在f1下与AP建立关联，然后依次是站点2在f1下与AP建立关联，站点3在f2下与AP建立关联，则AP先为站点1分配AID1，然后依次为站点2分配AID2，为站点3分配AID3。
通过这种分配方式，每个工作在多个频段的站点只能获得一个AID。
方式22)分别在每个工作频段下为建立关联的每个站点分配唯一的关联标识。
在该实施例中，可以将接入点划分成所有工作频段等数量的虚拟接入点，即一个工作频段对应一个虚拟接入点。然后，由该虚拟接入点为通过对应频段建立关联的站点分配唯一的AID。
例如，所有的工作频段为f1、f2和f3，则将AP划分成AP11、AP12和AP13三个虚拟AP，AP11为通过f1建立关联的站点分配AID，AP12为通过f2建立关联的站点分配AID，AP13为通过f3建立关联的站点分配AID。
通过这种分配方式，每个工作在多个频段的站点可以获得多个AID，每个AID与每个频段对应，例如，若站点1可以工作在三个频段，则站点1有三个AID，这三个AID分别与这三个频段相对应。
在步骤S303中，AP生成信标帧，该信标帧中包含下行数据缓存指示信息位，该下行数据缓存指示信息位用于指示信标帧是否缓存有下行数据。
在步骤S304中，AP在当前站点的侦听频段向当前站点发送信标帧。
在步骤S305中，当前站点在当前站点的侦听频段下侦听接入点发送的信标帧。
在步骤S306中，若当前站点侦听到信标帧，则从信标帧中解析下行数据缓存指示信息位。
在步骤S307中，若下行数据缓存指示信息位指示信标帧缓存有下行数据，则当前站点在侦听频段的竞争期下向AP发送省电轮询帧，以获取下行数据。
需要说明的是，该实施例是以一个站点为例描述获取下行数据的过程，对于多个站点的情形，其实现过程与一个站点的情形类似，此处不赘述。
上述实施例，通过AP与当前站点之间的交互，使得AP将建立关联时所在的频段确定为当前站点的侦听频段，并在当前站点的侦听频段向当前站点发送信标帧，使得当前站点在当前站点的侦听频段下侦听AP发送的信标帧，以获取下行数据，从而解决 多频段下AP发送信标帧和当前站点侦听信标帧来获取下行数据的问题，使得AP和当前站点可以在多频段下进行通信，提高了系统的吞吐量及数据速率，也间接提高了频谱有效利用率。
图4是本申请一示例性实施例示出的另一种下行数据获取方法的信令流程图，该实施例从AP和当前站点交互的角度进行描述，如图4所示，该方法包括：
在步骤S401中，当前站点与AP建立关联。
在步骤S402中，AP为当前站点分配关联标识(AID)。
其中，AP可以采用步骤S302中的分配方式21)或分配方式22)为当前站点分配AID。
在步骤S403中，当前站点通过协商帧与AP协商当前站点的休眠周期，其中，协商帧中携带当前站点的侦听频段，建立关联时所在的频段与该侦听频段不同。
当前站点在与AP建立关联之后，如果要处于休眠状态，则与AP协商其休眠周期，其中，该协商帧中携带当前站点的侦听频段，建立关联时所在的频段与该侦听频段不同。
在步骤S404中，AP生成信标帧，该信标帧中包含下行数据缓存指示信息位，该下行数据缓存指示信息位用于指示信标帧是否缓存有下行数据。
处于休眠状态的STA要与AP保持时间上的同步，则需要周期性地苏醒来侦听beacon帧中的时间同步功能信息来与AP保持时间上同步。对于优先级比较低的下行数据，AP可以将下行数据缓存指示信息位与当前站点的苏醒周期放置同一beacon帧中，以节省站点的电能。
在步骤S405中，AP在当前站点的侦听频段向当前站点发送信标帧。
在步骤S406中，当前站点在当前站点的侦听频段下侦听接入点发送的信标帧。
在步骤S407中，若当前站点侦听到信标帧，则从信标帧中解析下行数据缓存指示信息位。
在步骤S408中，若下行数据缓存指示信息位指示信标帧缓存有下行数据，则当前站点在侦听频段的竞争期下向AP发送省电轮询帧，以获取下行数据。
需要说明的是，该实施例是以一个站点为例描述获取下行数据的过程，对于多个站点的情形，其实现过程与一个站点类似，此处不赘述。
上述实施例，通过AP与当前站点之间的交互，通过协商帧携带当前站点的侦听频段，并在当前站点的侦听频段向当前站点发送信标帧，使得当前站点在当前站点的侦听频段下侦听AP发送的信标帧，以获取下行数据，从而解决多频段下AP发送信标帧和当前站点侦听信标帧来获取下行数据的问题，使得AP和当前站点可以在多频段下进行通信，提高了系统的吞吐量及数据速率，也间接提高了频谱有效利用率。
图5是根据一示例性实施例示出的一种下行数据缓存指示装置的框图，该下行数据缓存指示装置位于AP中，如图5所示，该下行数据缓存指示装置包括：生成模块51和发送模块52。
生成模块51被配置为生成信标帧，信标帧中包含下行数据缓存指示信息位，下行数据缓存指示信息位用于指示信标帧是否缓存有下行数据。
其中，当该下行数据缓存指示信息位为第一预设值，例如为“1”时，指示该信标帧缓存有下行数据，当该下行数据缓存指示信息位为第二预设值，例如为“0”时，指示该信标帧未缓存有下行数据。
在该实施例中，可以根据待缓存下行数据的优先级，将苏醒周期所在信标帧中的下行数据缓存指示信息位设置为缓存有下行数据。
例如，对于低优先级的下行数据，可以将苏醒周期所在信标帧中的下行数据缓存指示信息位设置为缓存有下行数据，即将下行数据缓存指示信息位和苏醒周期设置在同一信标帧中，同时站点获得在信标帧中的时间同步功能(time synchronization function，简称TSF)信息，以便与接入点保持时间上同步，这样复用了信标帧中的TSF和下行数据缓存指示信息位，有利于节省站点的电能。
发送模块52被配置为在每个站点的侦听频段向对应站点发送生成模块51生成的信标帧，侦听频段为对应站点侦听获取下行数据的频段。
可选地，发送模块52在每个站点的侦听频段向对应站点发送生成模块51生成的信标帧之前，该发送模块52还可以确定每个站点的侦听频段。
其中，确定每个站点的侦听频段可以包括：与每个站点建立关联，将建立关联时所在的频段确定为每个站点的侦听频段。
由于AP根据不同频段下的负载情况和在竞争期内发生冲突的情况来确定每个站点的监听频段，因此，所确定的监听频段可能与建立关联时所在的频段不同，在这种情况下，可以通过协商帧携带为每个站点确定的侦听频段，侦听频段用于侦听接入点广播 带有下行数据缓存指示信息位的信标帧。其中，该协商帧也用于AP与每个站点之间协商每个站点的休眠周期。
在该实施例中，在确定好每个站点的侦听频段之后，在每个站点的侦听频段向对应站点发送信标帧，每个站点在对应的侦听频段侦听信标帧，对侦听到的信标帧进行解析，以获取下行数据。
上述实施例，通过在每个站点的侦听频段向对应站点发送包含下行数据缓存指示信息位的信标帧，从而解决了在多频段下AP如何发送beacon帧的问题。

侦听模块61被配置为在当前站点的侦听频段下侦听接入点发送的信标帧。
可选地，侦听模块61在侦听接入点发送的信标帧之前，还与接入点建立关联，将建立关联时所在的频段确定为当前站点的侦听频段。
由于AP根据不同频段下的负载情况和在竞争期内发生冲突的情况来确定每个站点的监听频段，因此，所确定的监听频段可能与建立关联时所在的频段不同，在这种情况下，可以通过协商帧携带为每个站点确定的侦听频段。其中，该协商帧用于当前站点与AP之间协商当前站点的休眠周期。
在确定好当前站点的侦听频段之后，在该侦听频段下侦听接入点发送的信标帧。
解析模块62被配置为若侦听模块61侦听到信标帧，则从信标帧中解析下行数据缓存指示信息位。
