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公开实施例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、本公开实施例的一些方面相一致的装置和方法的例子。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”及“若”可以被解释成为“在……时”或“当……时”或“响应于确定”。
为了更好地描述本公开任一实施例，本公开一实施例以一个电表智能控制系统的应用场景为例进行示例性说明。
如图1所示，本公开一实施例提供一种电表智能控制系统应用场景。请参见图2，电表智能控制系统包括电站控制中心21、接入点22、电表1、电表2和电表3等。需要说明的是，电站控制中心可以是电表智能控制系统中的智能网关。接入点可以是路由器。这里，电表为本公开实施例中的 站点(STA，Station)。根据智能控制系统的调度需求，电站控制中心可以向接入点发送调度指令，指示接入点将存储的缓存数据配置给电表。这里，为了省电，电表可以是处于休眠状态，处于休眠状态的电表仍需要从接入点处获取缓存数据以实时执行对应的应用功能。
如图2所示，为本公开一实施例提供的一种进入休眠状态的站点获取缓存数据的方法示意图。请参见图2，站点在进入休眠状态之前，会与接入点协商苏醒周期来侦听信标帧(beacon)。站点周期性地苏醒以侦听接入点(AP，Access Point)发送的信标帧，并解析传输指示图(TIM，Traffic Indication Map)，以获知接入点是否缓存有站点的下行传输。如果接入点缓存有站点的下行传输，则站点在竞争期内发送省电轮询帧(PS-poll，Power Saving poll)以获得资源来接收接入点缓存的下行数据。这里，发送省电轮询帧的方式包括两种：
第一种方式：站点在接收信标帧的连接下发送省电轮询帧，且在多个传输连接下同步接收缓存下行传输；
第二中方式：在每个连接下发送省电轮询帧，且在每个连接下独立接收缓存下行传输，在这种方式下，不同连接下接收的缓存下行传输的时间可相同或不同。为本公开一实施例提供的一种进入休眠状态的站点获取缓存数据的方法。站点在进入休眠状态之前会与接入点协商苏醒周期，周期性的在接入点规定的服务阶段(SP，service period)内获取接入点为其缓存的下行传输。这里，站点与接入点协商苏醒周期。在非竞争期内，接入点通过非竞争轮询帧来发送接入点缓存的下行传输。这里，非竞争轮询帧由接入点发送给站点。这里，可以是在每个频段下发送，站点基于非竞争轮询帧接收缓存下行传输。
所述多个传输连接所使用的频率是不同的，例如，多个传输连接所使用的频率可以2.4GHz、5.8GHz及6-7GHz中的一个或多个。
本公开实施例的下行传输包括：下行业务数据和/或下行控制信令。
如图3所示，本实施例提供一种数据传输方法，其中，该方法可应用于应用于站点(Station，STA)，，所述方法包括：
S310：确定包含至少一个TIM广播请求IE的第一消息；其中所述TIM广播请求IE，至少用于指示接收下行传输的传输连接；
S320：在多个传输连接中的一个传输连接上发送所述第一消息。
此处的下行传输包括但不限于：接入点(Access Point，AP)缓存的下行传输。
此处的多个传输连接为同一个STA的多个传输连接，该STA为支持多传输连接的STA。
在本公开实施例中，水表、电表或者可穿戴式设备等站点会发送第一消息，该第一消息携带有TIM广播请求IE，其中该TIM广播请求IE中指示了用于接收接收下行传输的一个或多个传输连接。这样在一个第一消息的TIM广播请求IE中可以携带用于接收下行传输(例如，AP缓存的下行数据)的一个或多个传输连接的指示信息，从而使得被指示的用于接收下行传输的传输连接可为一个或多个，如此，STA可以在一个传输连接上完成多个传输连接是否为接收下行传输(例如，AP缓存的下行传输)的传输连接的指示，相当于在各个传输连接上单独发送和协商，减少了信令开销。
在一些实施例中，所述第一消息和第二消息都可以单独以帧的形式发送，则此时，所述第一消息可对应于第一消息帧；第二消息可对应于第二消息帧。在另一些情况下，所述第一消息和第二消息可以是以子帧的形式发送等，具体的发送形式此处不做限定。
在一些实施例中，该TIM广播请求IE可为用于STA与AP之间协商发送该TIM广播请求IE的传输连接上TIM信息的传输周期的IE。在本 公开实施例中，该TIM广播请求IE被扩展，可以在一个传输连接上发送的多个TIM广播请求IE中携带多个传输连接是否被建议用于接收AP缓存的下行传输的连接信息。如此，在不用引入新的IE的情况下，通过对原有的TIM广播请求IE的扩展，就简便的实现了对针对多传输连接的STA建议接收AP缓存的下行传输的指示。
图4可为的TIM广播请求IE的信息结构，而图5可为本公开提供的能够指示STA建议的一个或多个用于接收AP缓存的下行传输的传输连接。在图4及图5中元素ID用于指示TIM广播请求IE的标识。在图4和图5中的长度(Length)字段，可以用于指示该IE的长度，即该IE占用的比特数。该连接标识可用于携带指示STA建议的用于接收AP缓存的下行传输的传输连接，例如，在图5中有Link1及Link2等。
在本公开实施例中“传输连接”又可以简称为“连接”；如此，一个传输连接与一个连接为同义词。
在本公开实施例中，该STA可为支持多传输连接的任意类型的终端设备。该STA可以在一个或多个带宽上与AP建立多个传输连接。
例如，在STA为了节省功耗的休眠期间或其他不可接收状态，AP有接收到其他设备发送给STA的下行传输，但是STA处于休眠期间或其他不可接收状态，AP将接收的待发送给STA的数据缓存；响应于STA进入到激活状态或其他可接收状态，则AP需要通过与STA之间的一个或多个传输连接将AP为STA缓存的下行传输发送给STA。
在本公开的一些实施例中，下行传输为下行数据；或，下行传输为信令；或，下行传输为下行数据和信令的混合传输。
此处的一个或多个传输连接为STA与AP关联的多个传输连接中的一个或多个。
例如，在一些实施例中，一个所述STA具有M个传输连接，在所述 TIM广播请求IE中设置有M个比特序列，一个比特序列用于指示一个传输连接的连接信息，该连接信息包括但不限于：对应传输连接的连接标识、是否为STA建议的接收AP缓存的下行数据包的传输连接的指示信息。如此，AP接收到该TIM广播请求IE之后就知道STA当前建议在哪些传输连接上向STA发送AP缓存的下行传输。
在本公开的一些实施例中，连接信息还可以包括每一传输连接的连接参数。在本公开的一些实施例中，连接参数包括但不限于：TIM信息的传输周期，该传输周期可以由TIM广播响应IE中的TIM广播间隔字段来携带(TIM broadcast interval)。
在一些实施例中，STA发送的一个TIM广播请求IE中M个比特序列所指示的连接信息中，只包括一个传输连接；即只建议在一个传输连接下接收所述下行传输；剩余传输连接均不建议用于接收AP缓存的下行传输。例如，STA在传输连接3(Link3)中发送的一个TIM广播请求IE中M个比特序列所指示的连接信息，只包括一个传输连接1(Link1)；即只建议在一个传输连接Link1下接收所述下行传输；其他传输连接均不建议用于接收AP缓存的下行传输。
也就是说，STA在一个传输连接中发送TIM广播请求IE，且该TIM广播请求IE中包括一个或多个传输连接的指示信息，这些被指示的传输连接既可以是用于发送TIM广播请求IE的传输连接，也可以不是用于发送TIM广播请求IE的传输连接，还可以包括用于发送TIM广播请求IE的传输连接和其他传输连接。
在另一些实施例中，所述TIM广播请求IE携带有STA建议的用于接收AP缓存的下行传输的一个或多个传输连接的连接标识。例如，由于STA的多个传输连接使用的传输频带不同或者传输子带不同，则存在多个STA和多AP的无线环境中，不同传输频带或不同传输子带上的传输 干扰是不同的，即多个传输连接的信道质量是不同的。STA可以根据其自身多个传输连接的信道质量选择信道质量最优的一个或多个传输连接作为STA建议给AP下发缓存的下行传输的传输连接，如此通过这样的方式，确保下行传输的接收质量。
再例如，由于STA的多个传输连接设备时，可能连接的相同的AP也可以连接的是不同的AP；在传输过程中，有的传输连接的负载是比较大的，考虑到提升通信质量及实现负载均衡，STA可以根据负载情况，通过所述TIM广播请求IE中向AP建议一个或多个传输连接接收AP缓存的下行传输。例如，通过所述TIM广播请求IE中向AP建议负载较低的一个或多个传输连接接收AP缓存的下行传输。
总而言之，在本公开实施例中仅通过一个TIM广播请求IE，就可以与AP之间协商多个传输连接对AP缓存的下行传输的接收情况，相对于在多个传输连接上的每一个传输连接上单独协商是否用于接收缓存的下行数据，能够减少信令开销，提升协商效率。
如图8所示，本实施例提供一种数据传输方法，其中，该方法可应用于应用于站点(Station，STA)，所述方法包括：
S410：接收AP返回的携带有TIM广播响应IE的第二消息；
在一些实施例中，该第二消息是AP基于第一消息中的TIM广播请求IE生成的，即AP根据TIM广播请求IE生成所述TIM广播响应IE指示，从而使得STA能够确定在所述TIM广播请求IE指示的一个或多个传输连接传输所述AP缓存的下行传输下行传输。在一些实施例中，该第二消息是AP基于相关技术中STA发送的任意格式的TIM广播请求IE生成的，即：STA是在每一个传输连接上分别发送该传输连接对应的TIM广播请求IE，则AP也可以根据所有这些TIM广播请求IE，只生成一个第二消息，且这一个第二消息中的包括针对每一传输连接的TIM广播请 求IE所生成的TIM广播响应IE。
在第一消息AP接收到STA发送的用于指示一个或多个传输连接的消息后，消息向STA返回第二消息。第二消息发送包含有TIM广播响应IE。该TIM广播响应IE可以用于指示AP是否同意在STA建议的一个或多个传输连接的下发AP缓存的下行传输。
本申请实施例中的第二消息，可以是基于第一消息由AP返回的携带有TIM广播响应IE的第二消息。
在另一些实施例中，第二消息可是对第三消息的回复，例如，终端发送第三消息，此处的第三消息可为哪个传输连接上发指示哪个传输连接是否用于接收下行传输的消息，具体如，第三消息为在第一连接上发送且用于指示第一连接是否接收AP缓存的下行传输的消息。
在一些实施例中，所述TIM广播响应IE包括：状态字段；所述状态字段至少包括第一指示比特；
所述第一指示比特具有第一比特值，所述第一指示比特指示：同意在所述TIM广播请求IE指示的传输连接传输所述AP缓存的下行传输；
或者，
所述第一指示比特具有第二比特值，所述第一指示比特指示：拒绝在所述TIM广播请求IE指示的传输连接传输所述AP缓存的下行传输。
在TIM广播响应IE中设置有状态字段，该状态字段可包括一个或多个比特；这些比特都有具体的指示含义。在相关技术中的TIM广播响应IE就已经有部分比特有明确的指示定义，但是有一些预留比特。本公开中的第一指示比特可为预留比特中的一个比特，当然也可以是新增加的比特。
此处的第一指示比特可为1个比特或多个比特。当所述第一指示比特为1个比特时，具有“0”及“1”两个比特值，此处的若第一比特值 可为“0”，则第二比特值可为“1”；若第一比特值为“1”，则第二比特值为“0”。如此，在TIM请求响应IE内状态字段的一个或多个第一指示比特，AP可以明确回复是否同意采用STA建议的一个或多个传输连接来传输AP为STA缓存的下行传输。
在一些实施例中，所述状态字段包括多个保留值，可以选择状态字段两个保留值来指示供AP来指示是否同意STA建议的采用对应的传输连接来接收AP缓存的下行传输。
AP可能连接有多个STA，AP根据自身与多个STA之间的传输连接，可能确定出当前STA建议的某一个或多个用于接收AP缓存的下行传输的传输连接的干扰大，则AP可能不会同意对应传输连接接收AP缓存的下行输数据帧。在本公开实施例中所述TIM广播响应IE中的每一个传输连接可对应于一个状态字段，如此，STA在TIM广播请求IE中每一个被建议用于接收AP缓存的下行传输的传输连接都会由其对应的状态字段中的第一指示比特的比特值来指示，AP是否同意采用该传输连接来接收所述AP缓存的下行传输。
图6所示为本公开实施例提供的一种TIM广播响应IE的结构示意图。在图6中所示的TIM广播响应IE包括：元素标识、指示IE的比特长度的长度字段；状态(Status)字段、TIM广播间隔字段、TIM广播偏移量字段、高TIM速率字段及低TIM速率字段等。所示TIM广播偏移量字段用于指示TIM信息传输的偏移量。高TIM速率字段指示高速传输TIM速率。所述低TIM速率字段指示低速传输TIM速率。
在一些实施例中，所述TIM广播请求IE及所述TIM广播响应IE均包括：
TIM广播间隔字段，用于指示TIM信息的传输周期，其中，所述TIM信息，用于指示待接收所述AP缓存的下行传输的站点。
TIM广播请求IE及TIM广播响应IE均原定用于协商传输该TIM广播请求IE的传输连接的TIM信息的传输周期的，故都包含TIM广播间隔字段。该TIM广播间隔字段用于指示TIM信息的传输周期。
TIM信息为AP根据自身为各个STA所缓存的下行数据，会周期性的下发TIM信息。该TIM信息中可能携带有(AID，Association Identity)，AID为AP分配给STA的标识。若STA接收到TIM信息之后，若该TIM信息内携带所有自身的AID，则知道AP有为自身缓存下行传输，则需要接收AP缓存的下行传输。
例如，STA进入休眠状态之后，会周期性的苏醒侦听AP广播的信标帧(beacon)，从而接收到携带在信标帧内的TIM信息。
若STA通过监听到的信标帧内的TIM信息发现自身的TIM信息，则会根据TIM广播请求IE和/或TIM广播响应IE，即结合与AP的协商在双方协商确定的一个或多个传输连接上接收所述AP缓存的下行传输。
在一些情况下，AP可能为一个STA分配一个AID，在另一些实施例中，AP可能为一个具有多传输连接能力的STA分配多个AID，即一个传输连接对应于一个AID；或者，2个或多个传输连接共享一个AID。总之，一旦AP为STA分配了AID，则分配的AID会下发给STA。例如，AID可以通过STA与AP初始关联或者重新关联的过程中，通过TIM广播响应IE下发给STA。
总之，本公开实施例中，STA接收到TIM广播响应IE之后，会根据TIM广播间隔字段，会确定出接收TIM信息的传输周期，然后根据传输周期，每间隔一个周期都去接收广播的TIM信息，从而确实是否有缓存的下行传输。
在一些实施例中，所述响应于所述TIM广播响应IE指示同意，在所述TIM广播请求IE指示的传输连接上接收所述下行传输，包括：
响应于所述TIM广播响应IE指示同意且所述TIM信息指示有待接收所述AP缓存的下行数据，在所述TIM广播请求IE指示的传输连接上接收所述下行传输。
例如，TIM广播响应IE同意STA通过TIM广播请求IE建议的一个或多个接收AP缓存的下行输数据帧的传输连接，则后续STA会在建议的一个或多个传输连接上，接收AP下发的为STA缓存的下行传输。
例如，在TIM广播请求IE中STA可能建议在自身的N个传输连接中的M个传输连接上传输AP缓存的下行传输。此时，AP可能通过TIM广播响应IE指示通过在m个传输连接上传输AP缓存的下行传输，指示拒绝在剩余的M-m个传输连接上传输AP缓存的下行传输，则此时，后续STA可以在AP同意的m个传输连接上接收AP缓存的下行传输。若TIM广播响应IE拒绝STA在TIM广播请求IE中建议的所有用于接收AP缓存的下行输数据帧的传输连接。
在一种情况下，STA可以根据前一次TIM广播请求IE的建议的传输连接，通过TIM广播请求IE的再次发送与AP重新协商用于接收AP缓存的下行传输的传输连接。
在另一种情况下，若AP拒绝STA建议的用于接收AP缓存的下行传输的传输连接时，AP会直接在TIM广播响应IE中指示用于接收AP缓存的下行传输的传输连接。例如，在对应传输连接的状态字段包含第三指示比特，由第三指示比特指示对应的传输连接是由AP确定的用于接收AP缓存的下行传输的传输连接。如此，可以缩短协商时长，提升确定效率。
在一些实施例中，所述方法还包括：
响应于所述TIM广播请求IE包含的TIM广播间隔字段，和所述TIM广播响应IE包含的TIM广播间隔字段指示的所述传输周期不同，根据所 述TIM广播响应IE包含的TIM广播间隔字段指示的传输周期，接收所述接入点AP发送的TIM信息；
或者，
响应于所述TIM广播请求IE包含的TIM广播间隔字段，和所述TIM广播响应IE包含的TIM广播间隔字段指示的所述传输周期相同，根据所述TIM广播响应IE指示的传输周期或所述TIM广播请求IE包含的TIM广播间隔字段指示的传输周期，接收所述接入点AP发送的TIM信息。
TIM广播请求IE和TIM广播响应IE中对应于相同传输连接的TIM广播价格字段指示的TIM信息的传输周期，可能相同也可能不同。考虑到AP可能同时连接多个STA，针对AP每一个传输连接上的无线环境和/或负载的不同，为了确保通信质量，能够更好的通过传输周期的差异化设置，可以确保通信质量。故若AP和STA对同一个传输连接指示的TIM信息的传输周期不同时，以AP在TIM广播响应IE所包含的TIM广播间隔字段的指示为准。
在一些实施例中，所述STA在设置所述TIM广播间隔字段时，可以将STA建议的接收AP缓存的下行传输的传输连接的TIM信息的传输周期，小于STA未建议接收AP缓存的下行传输的传输连接的TIM信息的传输周期。如此，可以减少非常有可能不必要接收AP缓存的下行传输的传输连接上TIM信息的监听频率，从而进一步减少STA的功耗。与此同时，若将建议接收AP缓存的下行传输的传输连接的TIM信息的传输周期设置的更小一下，若一旦该建议的传输连接被AP确认，则使用该传输连接能够通过更小的传输周期，确知AP是否有为STA缓存下行传输，若有，则STA会更加及时的接收到AP为STA缓存的下行传输。
在另一个实施例中，所述AP在设置所述TIM广播间隔字段时，可以将确定的接收AP缓存的下行传输的传输连接的TIM信息的传输周期， 小于不用于接收AP缓存的下行传输的传输连接的TIM信息的传输周期。如此，可以减少非常有可能不必要接收AP缓存的下行传输的传输连接上TIM信息的监听频率，从而进一步减少STA的功耗。与上述实施例同理，这样也可以降低STA接收AP缓存的下行传输的延时。
在特定情况下，若STA和AP通过TIM广播请求IE和TIM广播响应IE的交互，确定不用于接收AP缓存的下行传输的传输连接的TIM广播间隔字段指示的传输周期可为TIM广播间隔字段能够指示的最大值。在一些实施例中，所述TIM广播响应IE还包括：状态字段；所述状态字段至少包括第二指示比特；
所述第二指示比特携带第一比特值，所述TIM广播请求IE包含的TIM广播间隔字段和所述TIM广播响应IE包含的TIM广播间隔字段，指示的TIM信息不同；
或者，
所述第二指示比特携带第二比特值，所述TIM广播请求IE包含的TIM广播间隔字段和所述TIM广播响应IE包含的TIM广播间隔字段，指示的TIM信息相同。
在本公开实施例中，所述状态字段还包括第二指示比特，该第二指示比特，用于指示AP是否建议采用TIM广播请求IE内TIM广播间隔字段为对应传输连接设置的TIM信息的传输周期。
如果AP同意STA为对应传输连接设置的TIM信息的传输周期，会通过状态字段中的第二指示比特指示，如此，STA接收到TIM广播响应IE之后就可以通过解码状态字段的内容就能够知道AP是否同意STA建议的在该传输连接上侦听TIM信息的传输周期，若AP同意都可以不用继续解码TIM广播响应IE内的TIM广播间隔字段。若AP拒绝，则需要机继续解码TIM广播间隔字段，确定出AP为该传输连接设置的TIM信 息的传输周期。
在一些实施例中，所述状态字段包括的多个比特，能够携带多个比特序列；可以利用这些比特序列中的两个比特序列来指示AP是否同意TIM广播请求IE中的TIM广播间隔建议的TIM信息的传输周期。
在一些实施例中，所述TIM广播请求IE内不同所述传输连接的TIM广播间隔字段指示的所述TIM信息的传输周期相同；或者，所述TIM广播请求IE内不同所述传输连接的TIM广播间隔字段指示的所述TIM信息的传输周期不同；和/或，所述TIM广播响应IE内不同所述传输连接的TIM广播间隔字段指示的所述TIM信息的传输周期相同；或者，所述TIM广播响应IE内不同所述传输连接的TIM广播间隔字段指示的所述TIM信息的传输周期不同。
在TIM广播请求IE和/或TIM广播响应IE中为每一个传输连接都可配置单独的TIM广播间隔字段，如此，STA和/或AP都可以单独为每一个传输连接设置其TIM信息的传输周期。故在设置多个传输连接的TIM信息的传输周期时，任意两个传输连接的TIM信息的传输周期可以相同或不同。
具体如，STA和/或AP可以根据当前各传输连接的信道环境、竞争激励程度和/或负载率等，差异化的设置不同传输连接的TIM信息的传输周期，从而确保通信质量。
如图8所示，本实施例提供一种数据传输方法，其中，该方法可应用于应用于站点(Station，STA)，所述方法包括：S420：响应于切换接收所述下行传输，发送TIM广播请求消息；
S430：接收基于所述TIM广播请求消息返回的TIM广播响应帧；
S440：根据在TIM广播响应帧，接收搜索下行传输。此处的下行传输包括：AP缓存的下行传输。
在一段时间之后，STA和AP之间的无线环境发生了变化，一方面为了确保通信质量，另一方面为了尽可能实现高效及高质量的数据传输，在STA与AP之前协商的用于接收AP缓存的下行传输的传输连接，可能需要切换。例如，STA通过信道侦听，发现之前确定用于接收AP缓存的下行传输的传输连接的信道质量恶化，而之前确定不用于接收AP缓存的下行传输的传输连接的信道质量维持较好的状态，或者维持负载率较低的状态时，此时，STA可以在一个或多个传输连接上，向AP发送TIM广播请求消息，与AP之间重新协商接收用于接收AP缓存的下行传输的传输连接。
此时，所述TIM广播请求消息，可至少携带有STA建议更换后的用于接收AP缓存的下行传输的传输连接。例如，TIM广播请求消息携带有STA的多个传输连接的比特位图，该比特位图中一个比特可以对应于STA的一个传输连接，如此，通过比特位图中各个比特的指示，可以告知AP，STA重新建议的用于接收AP缓存的下行传输的传输连接。
在另一些实施例中，所述TIM广播请求消息也可以携带前述的TIM广播请求IE，来进行接收AP缓存的下行传输的传输连接的接收。
AP是否同意STA重新建议的接收下行输数据帧的传输连接，则AP可以通过TIM广播响应帧来进行指示。
总之在本公开实施例中STA和AP可以通过TIM广播请求帧和TIM广播响应帧的收发，根据当前的无线环境及各个传输连接的负载情况等，动态调整接收AP缓存的下行传输的传输连接，确保AP缓存的下行传输的接收质量。
此处的，TIM广播请求帧和TIM广播响应帧可为一种管理帧，例如，是一种新增的管理帧，至少可用于STA和AP之间更换用于接收AP缓存的下行传输的传输连接。
所述根据在TIM广播响应帧，接收AP缓存的下行传输，包括：
在TIM广播响应帧指示同意切换接收所述AP缓存的下行传输的传输连接时，在TIM广播请求消息指示的切换后的传输连接上接收AP缓存的下行传输；
或者，
在TIM广播响应帧指示拒绝切换接收所述AP缓存的下行传输的传输连接时，在所述TIM广播请求IE或所述TIM广播响应IE指示的切换前的传输连接上接收AP缓存的下行传输。
在一些实施例中，所述第一消息为：关联请求(association request)帧、重关联请求(reassociation request)帧或TIM广播请求帧；和/或，
所述第二消息为：关联响应(association response)帧或TIM广播响应帧。

若，STA在初始关联或者重新关联的传输连接上发送所述第一消息时，则STA可以在初始关联或者重新关联的过程中就能够发送所述第一消息，可以尽早的完成接收AP缓存的下行传输的传输连接的协商。
在一些实施例中，如图8所示的方法可以结合前述任意一个实施例一起使用，也可以单独使用，本公开实施例并不对此作出限定。
如图9所示，本实施例提供一种数据传输方法，其中，应用于接入点AP，所述方法包括：
S510：在STA的一个传输连接上接收第一消息；所述第一消息包含：TIM广播请求元素IE；
S520：根据所述TIM广播请求IE，确定所述站点多个传输连接中接收下行传输的一个或多个传输连接。
该站点可为具有多个传输连接的站点。
此处的下行传输包括但不限于AP缓存的下行传输。
本公开实施例应用于AP中，AP接收到第一消息之后，会确定出STA多个传输连接中用于接收AP缓存的下行传输的一个或多个传输连接。
在本公开实施例中，AP可以通过第一消息，可以与具有多个传输连接的STA中内哪些传输连接用于接收AP缓存的下行传输的一次性协商，从而相对于单独对每一个传输连接是否可用于接收AP缓存的下行传输的协商，可以减少信令开销，且简化STA和AP之间的协商过程，提升协商效率。
S520可包括：根据STA的多个连接的信道质量、各个传输连接的竞争激励程度和/或各个传输连接的负载率，根据确定TIM广播请求IE，选择出信道质量大于质量阈值、竞争激励程度低于竞争阈值和/或负载率低于负载阈值的一个或多个传输连接用于接收AP缓存的下行传输。
在一些实施例中，S520可包括：
根据STA的多个连接的信道质量、各个传输连接的竞争激励程度和/或各个传输连接的负载率，直接确定TIM广播请求IE中建议的一个或多个传输连接用于接收AP缓存的下行传输；

在一些实施例中，所述方法还包括：
根据是否同意在所述TIM广播请求IE指示的传输连接传输所述AP缓存的下行传输，向所述站点携带有TIM广播响应IE的第二消息。
例如，AP可以根据各个传输连接的信道质量和/或负载率等因素，考虑是否同意TIM广播请求IE指示的用于接收AP缓存的下行传输的传输连接，若AP同意和/AP拒绝，则第二消息内的TIM广播响应IE的内容是不同的，例如，TIM广播响应IE中的状态字段内的一个或多个指示是否同意的第一状态比特是不同的。
在一些实施例中，所述TIM广播响应IE包括：状态字段；所述状态字段至少包括第一指示比特；
所述第一指示比特具有第一比特值，所述第一指示比特指示：同意在所述TIM广播请求IE指示的传输连接传输所述AP缓存的下行传输；

在一些实施例中，所述TIM广播请求IE及所述TIM广播响应IE均包括：TIM广播间隔字段，用于指示TIM信息的传输周期，其中，所述TIM信息，用于指示待接收所述AP缓存的下行传输的站点。
在本公开实施例中，所述TIM广播请求IE和TIM广播响应IE，不仅用于协商接收AP缓存的下行传输的传输连接的协商，还用于各个传输连接的TIM信息的传输周期的协商，从而实现了一组交互的IE中实现了多种信息的协商，具有信令比特开销小的特点。
在一些是实施例中，所述方法还包括：根据所述TIM广播响应IE内TIM广播间隔字段指示的TIM信息的传输周期，发送所述TIM信息。
在协商TIM信息的传输周期时，最终是以AP确定的TIM信息的传 输周期为准，故会根据TIM广播响应IE内TIM广播间隔字段指示的TIM信息的传输周期，来发送TIM信息。例如，通过发送信标帧来发送所述TIM信息。
例如，所述TIM广播请求IE内不同所述传输连接的TIM广播间隔字段指示的所述TIM信息的传输周期相同；或者，所述TIM广播请求IE内不同所述传输连接的TIM广播间隔字段指示的所述TIM信息的传输周期不同；和/或，所述TIM广播响应IE内不同所述传输连接的TIM广播间隔字段指示的所述TIM信息的传输周期相同；或者，所述TIM广播响应IE内不同所述传输连接的TIM广播间隔字段指示的所述TIM信息的传输周期不同。
AP在设置各个传输连接的TIM信息的传输周期时，可以综合考虑到同频干扰、邻频干扰、负载率和/或一个STA的功耗等多方面因素，为不同的传输连接设置合适的TIM信息的传输周期。
例如，在信道状况较好的情况下，可以优先将同一个STA的多个传输连接的TIM信息的传输周期相同，则该STA可以在周期性苏醒侦听信标帧，降低STA苏醒的频次，尽可能降低STA的功耗。
在一些实施例中，所述TIM广播响应IE还包括：状态字段；所述状态字段至少包括第二指示比特；
所述TIM广播响应IE包含的TIM广播间隔字段和所述TIM广播请求IE包含的TIM广播间隔字段，指示的TIM信息不同，所述第二指示比特携带第一比特值；
或者，
所述TIM广播响应IE包含的TIM广播间隔字段和所述TIM广播请求IE包含的TIM广播间隔字段，指示的TIM信息相同，所述第二指示比特携带第二比特值。
在本公开实施例中，TIM广播响应IE中状态字段还包括第二指示比特，AP可以通过第二指示比特告知STA是否同意STA建议的TIM信息的传输周期。
在一些实施例中，所述方法还包括：
接收TIM广播请求消息；
基于所述TAIM广播请求消息发送TIM广播响应帧；其中，TIM广播响应帧，用于指示是否切换接收所述下行传输的传输连接。
在本公开实施例中，若STA确定需要重新协商确定接收AP缓存的下行传输，则回通过TIM广播请求消息与AP重新协商，此时AP会接收到TIM广播请求消息并通过TIM广播响应帧进行回应。此时，AP可以同意切换接收AP缓存的下行传输的传输连接，也可以拒绝切换AP缓存的下行传输的传输连接。
在另一些实施例中，AP也可以通过信标帧或重关联响应帧等发起接收AP缓存的下行传输的传输连接的协商。
在一些实施例中，所述方法，还包括：
在TIM广播响应帧指示同意切换接收所述下行传输的传输连接时，在TIM广播请求消息指示的切换后的传输连接上发送下行传输；
或者，

为了使得设备能够在多连接通信的情况下能够获得缓存的下行传输，从而满足IEEE802.11提高系统吞吐量及降低时延的愿景。
步骤1：站点在建立初始关联/重关联的连接中发送TIM广播请求(TIM broadcast request)信息元素站点在关联请求(association request)帧、重关联请求(reassociation request)或TIM广播请求帧(TIM Broadcast Request  frame)中带上TIM广播请求(TIM broadcast request)信息元素，其具体格式为：
其中，本公开实施例提供TIM广播请求IE可如图5所示。link1、link2标识站点将会在哪个连接下接收缓存的下行传输，TIM广播间隔(TIM broadcast interval)指示TIM信息的传输周期，可设置为在每个传输连接下一样，也可设置在每个传输连接下不一样。
步骤2：AP在关联响应(association response)帧或TIM广播响应(TIM broadcast response)帧中回复TIM广播响应(TIM broadcast response)IE。
AP回复的信息元素格式(即TIM广播响应IE)如图6所示：
连接(link)标识与上述的步骤1中的link一样，状态(status)字段的信息内容可如图7所示。
如果在步骤1中如果TIM广播间隔(TIM broadcast interval)与步骤2中的不一致，则以步骤2的为准，且status域设置为“2”，“denied”。如一致，则设置为“0”。
步骤3：站点与AP需标识其支持多连接通信。
AP在信标(beacon)帧、探测响应(probe response)帧或关联响应(association response)帧中携带，而STA则在探测请求(probe request)帧、关联请求(association request)帧中携带告知AP其支持多传输连接的信息。
步骤4：如有需要可以切换接收AP缓存的下行传输的传输连接。如STA想要切换接收缓存的连接，则发送TIM广播请求帧(Broadcast Request frame)，AP回复TIM广播响应帧(Broadcast Response frame)。
如此，使得设备能够在多连接通信时获取缓存的下行传输，满足IEEE802.11be在对连接下能够进行通信的需求。
