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、本公开的一些方面相一致的装置和方法的例子。
本公开实施例提供的设备省电方法应用于包括数据发送设备和数据接收设备的无线局域网通信系统中。数据发送设备和数据接收设备可为站点(Station，STA)或接入点(Access Point，AP)。数据发送设备与数据接收设备之间通过无线局域网执行数据的前向传输和回传。
其中，本公开中涉及的STA可以理解为是无线局域网中的用户终端，该用户终端可以称为用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、物联网(Internet of Things， IoT)客户端或者车载设备等。
本公开中涉及的AP指无线局域网用户终端接入网络的设备、路由器等。
相关技术中，STA和AP之间采用IEEE802.11标准进行数据帧传输。目前，IEEE802.11成立了SG(study group)IEEE802.11be来研究下一代主流(802.11a/b/g/n/ac/ax)Wi-Fi技术，所研究的范围为：320MHz的带宽传输，多个频段的聚合及协同等，所提出的愿景相对于现有的IEEE802.11ax提高至少四倍的速率以及吞吐量。其主要的应用场景为视频传输，AR、VR等。
其中，多个频段的聚合及协同是指同时在多个频段或同一频段中多个带宽进行通信，例如同时在2.4GHz、5.8GHz及6-7GHz三个频段下进行通信。同时在多个频段或同一频段中多个带宽中进行通信可以理解为是多连接通信，或者称为多链路聚合(Multi-link aggregation，MLA)。图1所示为多连接通信示意图。图1中第一设备和第二设备通过N个连接同时进行通信。其中，N为大于或等于2的正整数。
多连接通信下的设备如何进入休眠模式，是目前研究的热点。
本公开实施例提供一种设备省电方法，第一设备和第二设备之间在多个连接中同时传输数据帧，即采用多连接通信。第一设备生成包括标识信息位的消息帧，以下称为第一消息帧。第一消息帧中包括的标识信息位用于指示第一设备在与第二设备进行数据帧传输的多个连接中的一个或多个连接中进入休眠模式。第一设备向第二设备发送生成的第一消息帧。第二设备接收到第一消息帧后，向第一设备反馈用于确认或否定第一设备在标识信息位所指示进入休眠模式的连接中进入休眠模式的消息帧。以下将用于确认或否定第一设备在标识信息位所指示进入休眠模式的连接中进入休眠模式的消息帧称为第二消息帧。第一设备接收第二设备反馈的第二消息帧，依据第二消息帧确认是否在所述标识信息位所指示进入休眠模式的连接中进入休眠模式。进而，在第二消息帧表征确认第一设备在标识信息位所指示进入休眠模式的连接中进入休眠模式时，使得第一设备能够在多连接通信的情况下进入休眠模式，满足IEEE802.11be在多连接通信情况下能够满足设备省电通信的需求。
图2是根据一示例性实施例示出的一种设备省电方法的流程图，如图2所示，设备省电方法用于第一设备中，第一设备可以为STA，也可以是AP。第一设备与第二设备之间在多个连接中同时传输数据帧。第二设备可以为AP，也可以为STA。设备省电方法包括以下步骤。
在步骤S11中，生成第一消息帧。
本公开实施例中，第一消息帧中包括标识信息位，该标识信息位用于指示第一设备在多个连接的一个或一个以上个连接中进入休眠模式。
在步骤S12中，向第二设备发送第一消息帧。
本公开实施例中，第一设备向第二设备发送第一消息帧。第二设备接收到第一设备发送的第一消息帧后，可以根据实际情况确认是否允许第一设备进入休眠模式，并向第一设备反馈用于确认或否定第一设备进入休眠模式的第二消息帧。例如，第二设备正确接收完成第一设备发送的数据帧后，可以确认第一设备进入休眠模式。第二设备确定未完成与第一设备之间的通信，则可以否定第一设备进入休眠模式。
在步骤S13中，接收第二设备反馈的第二消息帧，并依据第二消息帧确认是否在标识信息位所指示进入休眠模式的连接中进入休眠模式。
本公开实施例中第二消息帧用于确认或否定第一设备在标识信息位所指示进入休眠模式的连接中进入休眠模式。在第二消息帧用于确认第一设备在标识信息位所指示进入休眠模式的连接中进入休眠模式时，第一设备确认在标识信息位所指示进入休眠模式的连接中进入休眠模式。在第二消息帧用于否定第一设备在标识信息位所指示进入休眠模式的连接中进入休眠模式时，第一设备在标识信息位所指示进入休眠模式的连接中不进入休眠模式，继续进行通信。
本公开实施例提供的设备省电方法，使得第一设备能够实现在多连接通信的情况下进入休眠模式，满足IEEE802.11be在多连接通信情况下能够满足设备省电通信的需求。
本公开实施例以下将结合实际应用对上述涉及的多连接情况下进入休眠模式的实施过程进行说明。
本公开实施例以下以第一设备为STA，第二设备为AP为例进行说明。当然也可以是第一设备为AP，第二设备为STA。本公开实施例不作限定。
本公开实施例中，STA生成的第一消息帧可以为数据消息帧或者管理消息帧。STA在与AP进行多连接通信的过程中，可以在数据消息帧或管理消息帧的媒体接入控制(Media Access Control，MAC)帧头中的帧控制域(frame control，FC)中包括的电源管理(power management)子域设置标识信息位。图3所示为一示例性实施例提供的MAC帧头格式示意图。
其中，本公开实施例中第一消息帧中的标识信息位可以是比特位，并通过比特位置位的方式得到不同的比特位取值，不同的比特位有不同的取值。不同取值的比特位可以用于指示第一设备是否进入休眠模式。例如，将MAC帧头的FC域中的power management子 域中的比特位设置为“1”，标识STA将进入休眠模式(省电模式)。将MAC帧头的FC域中的power management子域设置为“0”，标识STA将不进入休眠模式，继续进行数据帧传输。
本公开实施例中，STA在多个连接中的每一个连接下可以分别选择进入休眠模式，或者不进入休眠模式。故，STA可以根据在多个连接中的每一连接中分别向AP发送第一消息帧，并在各连接中发送的每个第一消息帧中分别指示各自在当前连接中是否进入休眠模式。
本公开实施例中，若STA在与AP进行多连接通信的全部连接中进入休眠，则STA可以在与AP进行关联的连接中苏醒并侦听缓存下行数据帧，以及获取与AP保持同步通信的时间同步信息。
进一步的，本公开实施例中，STA通常是在完成所有数据帧的发送后进入休眠模式，故本公开实施例中为保证数据帧的完全发送，STA可以是在完成数据帧传输后向AP发送第一消息帧。例如，第一消息帧为数据消息帧时，数据消息帧为STA在当前连接中向AP发送的最后一个数据帧。第一消息帧为管理消息帧时，STA在当前连接中向AP发送完成全部数据帧之后发送管理消息帧。
更进一步的，本公开实施例中，第二消息帧可以复用回复确认(ACK)帧。在ACK帧的MAC帧头中的FC域中的power management子域设置用于确认或否定STA进入休眠模式的标识信息位。例如，设置ACK帧的FC域power management子域为“1”，标识STA可进入休眠模式。设置ACK帧的FC域power management子域为“0”，标识STA不能进入休眠模式。
在IEEE802.11be中STA和AP之间可以有两种多连接下的通信模式：异步通信模式和同步通信模式。在异步通信模式下，多连接中的每个连接下接入信道都是相互独立的。如图4所示，连接1、连接2和连接3为异步通信模式，STA传输的数据帧在三个连接下之间彼此相互独立，异步传输。在同步通信模式下，每个连接下接入信道是相互关联的。如图5所示，STA在连接1和连接2中传输的数据帧存在同步传输，以及连接2和连接3中传输的数据帧存在同步传输。
在异步通信模式下，每个连接下接入信道都是相互独立的，所以对于这种模式下的STA与AP进行多连接通信时，可以针对多个连接中的每一个连接生成第一消息帧，并在多个连接中的每一连接中发送第一消息帧。例如，设置每个连接下发送的数据帧或管理帧的MAC帧头中的FC域power management子域为“1”，标识STA在每个连接下将进入 休眠模式。
其中，若STA在与AP进行多连接通信的全部连接中进入休眠，则STA可以在与AP进行关联的连接中苏醒并侦听缓存下行数据帧，以及获取与AP保持同步通信的时间同步信息。
在同步的通信模式下，每个连接下接入信道是相互关联的，所以对于这种模式下STA与AP进行通信时，一方面，可以针对多个连接中的每一个连接生成第一消息帧，并在多个连接中的每一连接中发送第一消息帧。另一方面，也可以在与AP进行关联的连接中向AP发送第一消息帧。第一消息帧中的标识信息位用于指示STA在进行同步通信的多个连接中进入休眠模式。例如，图4所示的同步通信过程中，STA可以在与AP进行关联的连接中向AP发送第一消息帧，第一消息帧中的表示信息位用于指示STA在连接1和连接2中将进入休眠模式，也可以用于指示STA在连接2和连接3中将进入休眠模式。本公开实施例中，在同步通信模式下，通过一个连接中发送的第一消息帧指示STA在多个同步通信的连接中进入休眠模式，故第一消息帧中标识信息位的数量可以是多个。标识信息位的数量依据当前进行同步通信的连接数量确定，以保证能够指示STA在当前进行同步通信的全部连接中进入休眠模式。例如，本公开一实施例中，STA可在与AP进行关联得连接中传输的数据帧的MAC帧的帧头中的FC域power management子域中设置多个比特位，多个比特位中的每个比特位用于标识STA在一个连接中是否进入休眠模式。例如，比特位设置为“1”，表示STA在该连接中进入休眠模式。比特位设置为“0”表示STA在该连接中不进入休眠模式。
本公开另一实施例中，STA可在与AP进行关联得连接中传输的数据帧的MAC帧的帧头中的FC域power management子域多预设一个比特位，以指示STA在当前进行同步通信的全部连接中进入休眠模式。如果MAC帧的帧头中的该预设的一个比特位设置为“1”，则表示所有的连接下的FC域power management子域为“1”，表示STA将要进入休眠模式。如MAC帧的帧头中的该预设的一个比特位设置为“0”，表示同步通信的多个连接中有部分连接的FC域power management子域为“1”，STA将进入休眠模式。表示同步通信的多个连接中也有部分连接的FC域power management子域为“0”，STA将不进入休眠模式，继续进行通信。
其中，若STA在与AP进行多连接通信的全部连接中进入休眠，则STA可以在与AP进行关联的连接中苏醒并侦听缓存下行数据帧，以及获取与AP保持同步通信的时间同步信息。或站点随机的选取一个连接苏醒来与AP保持时间上的同步。或由AP指定一个连 接站点苏醒与AP保持时间上的同步。
本公开一实施例中，STA在与AP进行多连接通信过程中，可以在某些连接下切换进入休眠模式的连接。例如，由于连接负载较大，可以动态切换到其他负载较小的连接中继续进行通信，该连接负载较大的连接将进入休眠模式。也可以是，已进入休眠模式的连接切换为继续通信。在确认切换进入休眠模式的连接时，本公开实施例中需要更新第一标识位中用于标识进入休眠模式连接的标识信息位。
本公开上述实施例中，STA与AP进行多连接通信时，通过标识信息位标识进入休眠模式，使得STA能够在多连接通信的情况下进入休眠模式，满足IEEE802.11be在对连接下能够进行通信的需求。
图6是根据一示例性实施例示出的一种设备省电方法的流程图，如图6所示，设备省电方法用于第二设备中，第二设备可以为AP，也可以是STA。第二设备与第一设备之间在多个连接中同时传输数据帧。第一设备可以为STA，也可以为AP。设备省电方法包括以下步骤。
在步骤S21中，接收第一设备发送的第一消息帧。
其中，第一消息帧中包括标识信息位，标识信息位用于指示第一设备在多个连接的一个或一个以上个连接中进入休眠模。
在步骤S22中，向第一设备反馈第二消息帧。
其中，第二设备接收到第一设备发送的第一消息帧后，可以根据实际情况确认是否允许第一设备在标识信息位所指示进入休眠模式的连接中进入休眠模式，并向第一设备反馈用于确认或否定第一设备在标识信息位所指示进入休眠模式的连接中进入休眠模式的第二消息帧。例如，第二设备在标识信息位所指示进入休眠模式的连接中正确接收完成第一设备发送的数据帧后，可以确认第一设备在标识信息位所指示进入休眠模式的连接中进入休眠模式。第二设备确定在标识信息位所指示进入休眠模式的连接中未完成与第一设备之间的通信，则可以否定第一设备在标识信息位所指示进入休眠模式的连接中进入休眠模式。
本公开实施例中，第二消息帧可以复用回复确认(ACK)帧。在ACK帧的MAC帧头中的FC域中的power management子域设置用于确认或否定STA进入休眠模式的标识信息位。例如，设置ACK帧的FC域power management子域为“1”，标识确认第一设备在标识信息位所指示进入休眠模式的连接中进入休眠模式。设置ACK帧的FC域power management子域为“0”，标识否定第一设备在标识信息位所指示进入休眠模式的连接中 进入休眠模式，即第一设备不能在标识信息位所指示进入休眠模式的连接中进入休眠模式。
本公开实施例中，第二设备接收第一消息帧并反馈第二消息帧的实施过程，可以与第一设备发送第一消息帧的形式相对应。例如，第二设备可以在多个连接中的每一连接中接收第一设备发送的第一消息帧。第一消息帧中的标识信息位用于指示第一设备在发送第一消息帧的当前连接中进入休眠模式。并且第二设备在多个连接中的每一连接中，向第一设备反馈第二消息帧。
例如，第一设备与第二设备之间在多个连接中采用异步通信模式传输数据帧。由于接入信道是相互独立的，所以AP会在每个连接下回复ACK帧，设置ACK帧的FC域power management子域为“1”，标识站点可进入休眠模式。
当然，本公开实施例中，不排除在某个连接下回复ACK来确认站点是否进入休眠模式，设置ACK帧的FC域power management子域为“1”。
第一设备与第二设备之间在多个连接中采用同步通信模式传输数据帧。第二设备在与第二设备进行关联的连接中接收第一设备发送的第一消息帧。第一消息帧中的标识信息位用于指示第一设备在进行同步通信的多个连接中进入休眠模式。
例如，AP同时接收到STA在每个连接下发送的数据帧/关联帧，但在一个连接下回复ACK帧标识站点进行休眠模式。若STA在关联帧中新增的预设比特位方式传输第一消息帧，例如设置为“1”，则AP在ACK帧的MAC帧头的FC域的power management子域也设置为“1”，标识AP在所有连接下进行休眠模式。若STA在关联帧中新增的预设比特位设置为“0”，则AP在ACK帧的MAC帧头的FC域power management子域也设置为“0”，标识AP按照上述第一设备在某些连接下进入休眠模式或者切换进入休眠模式的连接。
本公开实施例中，第一消息帧为数据消息帧或者管理消息帧。数据消息帧或管理消息帧的媒体接入控制MAC帧头中包括帧控制域，帧控制域中包括电源管理子域，电源管理子域中包括标识信息位。
其中，在第一消息帧为数据消息帧时，第二设备通过接收当前连接中的最后一个数据帧接收第一消息帧。在第一消息帧为管理消息帧时，第二设备在当前连接中接收完成全部数据帧后接收第一消息帧。
图7是根据一示例性实施例示出的一种设备省电方法的流程图，如图7所示，设备省电方法用于第一设备和第二设备进行交互的过程中。参阅图7所示，包括如下步骤。
在步骤S31中，第一设备生成第一消息帧。
第一消息帧中包括标识信息位，所述标识信息位用于指示所述第一设备在所述多个连接的一个或一个以上个连接中进入休眠模式。
在步骤S32中，第一设备向第二设备发送第一消息帧。第二设备接收第一设备发送的第一消息帧。
在步骤S33中，第二设备向第一设备反馈第二消息帧。第一设备接收第二设备反馈的第二消息帧。
本公开实施例中第二消息帧用于确认或否定第一设备进入休眠模式。
在步骤S34中，第一设备依据第二消息帧确认是否在标识信息位所指示进入休眠模式的连接中进入休眠模式。
在第二消息帧用于确认第一设备在标识信息位所指示进入休眠模式的连接中进入休眠模式时，第一设备确认在标识信息位所指示进入休眠模式的连接中进入休眠模式。在第二消息帧用于否定第一设备进入休眠模式时，第一设备不进入休眠模式，继续进行通信。
可以理解的是，上述实施例涉及的第一设备和第二设备在进行设备省电通信过程中的实施过程彼此适用，并适用本公开实施例中第一设备与第二设备进行交互的实施过程。故对于本公开实施例中，对于第一设备和第二设备交互实现设备省电的实施过程可参阅上述实施例的相关描述，在此不再赘述。
基于相同的构思，本公开实施例还提供一种设备省电装置。
可以理解的是，本公开实施例提供的设备装置为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。结合本公开实施例中所公开的各示例的单元及算法步骤，本公开实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能，但是这种实现不应认为超出本公开实施例的技术方案的范围。
