具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：WLAN通信系统、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)系统、第五代(5th generation，5G)系统、新无线(new radio，NR)、未来的第六代(6th generation，6G)系统等。
示例的，本申请实施例可以应用于WLAN系统，并且本申请实施例可以适用于WLAN所采用的电气与电子工程师协会(institute of electrical and electronics engineers，IEEE)802.11系列协议中的任意一种协议，比如802.11a/b/g、802.11n、802.11ac、802.11ax、802.11be、802.11bf以及未来的802.11协议。本申请提供的方法可以由无线通信系统中的通信设备或通信设备中的芯片或处理器实现，相应地，该通信设备支持采用IEEE 802.11系列协议进行通信。虽然本申请实施例主要以部署IEEE 802.11的网络为例进行说明，本领域技术人员容易理解，本申请涉及的各个方面可以扩展到采用各种标准或协议的其它网络，例如，BLUETOOTH(蓝牙)，高性能无线局域网(local area network，LAN)(high performance radio LAN，HIPERLAN)(一种与IEEE 802.11标准类似的无线标准，主要在欧洲使用)以及广域网(wide area network，WAN)、WLAN、个人区域网(personal area network，PAN)或其它现在已知或以后发展起来的网络。因此，无论使用的覆盖范围和无线接入协议如何，本申请提供的各种方面可以适用于任何合适的无线网络。
随着WLAN，4G以及5G等通信技术的发展，各类无线通信设备已大量部署在人们的日常生活中。无线通信设备可以包括手机、电脑、无线路由器、智能家居设备及无线传感器等。例如在家庭环境中往往有几个、十几个甚至上百个无线通信设备，这些无线通信设备在通信过程中可能存在冲突。
在WLAN通信系统中，通常使用CSMA/CA载波监听技术主动避免碰撞，降低产生冲突的概率。但是对于Wi-Fi多用户的场景下，会存在隐藏节点以及竞争冲突的情况，导致多个设备同时进行数据传输，出现干扰丢包，大大降低Wi-Fi性能及用户体验。隐藏节点场景如图1所示，站点(station，STA)1和STA2位于接入点(access point，AP)的信号覆盖范围内，STA1、STA2连接AP，AP可以与STA1、STA2通信。但是由于STA1和STA2之间因为距离等因素无法直接通信，对于STA1来说，STA2属于隐藏节点，对于STA2来说，STA1属于隐藏节点，STA1和STA2可能同时向AP发送数据，AP接收到信号就会出现冲突，AP无法解析STA1和STA2中任何一端的数据。
为了防止碰撞产生，802.11协议允许使用请求发送(request to send，RTS)/允许发送(clear to send，CTS)机制解决隐藏节点的问题。RTS/CTS机制的交互流程如图2所示，待传输数据的STA1向STA2发送RTS帧，在一段时间后，STA2向STA1发送CTS帧清空传输信道。STA1接收CTS帧之后，在传输信道上发送数据帧(frame)，如果STA2正确接收到数据frame，STA2向STA1发送确认(acknowledged，ACK)应答。虽然RTS/CTS可以有效解决隐藏节点的问题，但是RTS/CTS帧的交互会延长数据交互过程，增加额外的报文开销，影响Wi-Fi性能和可靠性。
或者为了防止碰撞产生，Wi-Fi的传输可以采用分布式协调功能(distributed coordination function，DCF)来竞争空口。如图3所示，DCF方式中，站点在试图传输数据之前，检查传输信道是否处于空闲状态，若传输信道处于忙碌状态，站点利用指数型退避(orderly exponential backoff)算法确定退避时间(backoff time)，基于该退避时间延迟访问来避免碰撞发生。这个退避时间是随机的，但是随着站点数量的增加，不同站点随机到相同退避时间的概率也会增大，这种情况可能导致站点同时发送数据，例如STA1和STAx同时退避a个时隙发送数据，出现空口冲突，AP无法解析发送冲突的数据，影响Wi-Fi性能和可靠性。
基于此，本申请实施例提供了一种通信方法，在该通信方法中，接入点设备为至少一个站点设备分配对应的时间片，该至少一个站点设备在其对应的时间片上发送数据包，从而可以降低冲突的概率，提高Wi-Fi性能和可靠性。
参见图4，为本申请实施例提供的一种通信过程，包括如下步骤：
S401：接入点设备生成第一信息。
其中，第一信息包括为至少一个站点设备分配的时间片的信息，时间片用于至少一个站点设备在时间片上发送数据包。
S402：接入点设备向至少一个站点设备，发送第一信息，相应的，至少一个站点设备接收第一信息。
S403：站点设备生成数据包。
该站点设备属于接收到第一信息中的至少一个站点设备。
S404：站点设备在第一信息包括的时间片上，向接入点设备发送数据包，相应的，接入点设备接收数据包。
上述的接入点设备(如上述AP)是部署在无线通信系统中为其关联的站点设备提供无线通信功能的装置，通常为支持802.11系统标准的设备，例如路由器、网关、中继器，通信服务器，交换机或网桥等通信设备。
上述的站点设备(如上述STA)是具有无线通信功能的装置，通常为支持802.11系统标准的终端产品，例如手机、个人计算机(personal computer，PC机)(也称台式机)、笔记本电脑、娱乐设备、可穿戴设备或智能家居设备等。
上述的至少一个站点设备是与接入点设备通信的站点设备，通常指接入该接入点设备的站点设备，或者位于该接入点设备的信号覆盖范围的站点设备。
接入点设备可以通过获取到的站点设备的站点信息，确定与该接入点设备通信的站点设备。接入点设备可以通过如下方式获取站点设备的站点信息：
方式1：接入点设备接收来自站点设备的站点信息。
站点设备的站点信息包括但不限于以下一个或多个：设备标识、设备类型、是否为移动设备、位置信息、数据流量、或丢包率等。设备标识可以是设备编号、为站点设备分配的网际互联协议(internet protocol，IP)地址、或站点设备的媒体存取控制(media access control，MAC)地址等一个或多个标识信息。设备类型用于说明站点设备所属的类型，例如在智能家居场景中，设备类型包括以下一个或多个类型：手机、台式机、台灯、空调、电视机、电冰箱或洗衣机等。是否为移动设备一般指使用过程中位置是否可以移动，例如手机或笔记本电脑为移动设备，台式机、台灯或空调等非移动设备。位置信息用于表示站点设备所在的位置，例如在智能家居场景中，位置包括主卧、次卧、餐厅、或客厅等一种或多种位置。数据流量指站点设备在单位时间内传输数据量。丢包率是单位时间内丢失的数据包占发送的数据包的比率。
站点设备发送站点信息的时机可以包括如下一个或多个：
1.1站点设备接入到接入点设备时/后，向接入点设备发送该站点设备的站点信息；
1.2站点设备周期性地发送站点信息；
1.3在接收配网设备配置的站点设备的位置信息时/后，站点设备向接入点设备发送该站点设备的站点信息。
在该1.3中，配网设备(例如手机等终端)作为配网设备，安装有配网软件，该配网软件支持编辑户型的功能以及支持设置站点设备的位置(如设备在哪个房间)，用户基于该配网软件，可以编辑自己的家庭户型图，然后在户型图中的房间位置设置家居设备，从而实现终端配置站点设备的位置信息。配网设备配置站点设备的位置信息的相关描述在后文说明。
方式2：接入点设备接收来自配网设备配置的站点设备的站点信息。
配网设备发送站点设备的站点信息的时机可以包括如下一个或多个：
2.1配网设备周期性地发送站点设备的站点信息；
2.2在配网设备配置站点设备的位置信息时/后，配网设备向接入点设备发送站点设备的站点信息。
其中，配网设备配置站点设备的位置信息的相关描述在后文说明。
可选地，上述时间片是为站点设备组分配的时间片，该站点设备组包括上述的至少一个站点设备，即上述的至少一个站点设备属于一个站点设备组，其中，为不同站点设备组分配的时间片不同。示例的，接入点设备对与其通信的多个站点设备进行分组，得到一个或多个站点设备组，其中每个站点设备组包括一个或多个站点设备，接入点设备为每个站点设备组分配对应的时间片。
一种可能的实现中，接入点设备对多个站点设备进行分组时，接入点设备根据多个站点设备的站点 信息和分组策略，对多个站点设备进行分组。示例的，分组策略包括如下一个或多个策略：
策略1：位置信息属于同一房间的至少一个站点设备位于一个站点设备组，也就是说，时间片是为位置信息属于同一房间的至少一个站点设备分配的。
在该策略1中，接入点设备将同一房间内的站点设备划分到一个组，例如主卧包括空调和台灯，接入点设备可以将空调和台灯划分到一个组中。通常同一房间内的站点设备之间不会出现隐藏节点。
策略2：属于移动设备的一个站点设备单独位于一个站点设备组，也就是说，时间片是为属于移动设备的一个站点设备单独分配的。
在该策略2中，接入点设备将一个移动设备单独划分到一个组，例如将手机、笔记本电脑分别划分到一个组中。例如，将移动设备划分到卧室所在的分组，当移动设备离开卧室时，卧室内的其它站点设备无法感知到该移动设备，可能导致卧室内的站点设备和移动设备同时向接入点设备发送数据包，导致出现干扰丢包。
策略3：数据流量位于第一流量范围的一个站点设备单独位于一个站点设备组，也就是说，时间片是为数据流量位于第一流量范围的一个站点设备单独分配的。
在该策略3中，接入点设备将数据流量位于第一流量范围的一个站点设备单独划分到一个组，例如将台式机分别划分到一个组。
流量范围可以包括但不限于第一流量范围和第二流量范围，其中第一流量范围中的最小值大于或等于第二流量范围中的最大值，也就是说，位于第一流量范围内的数据流量大于或等于位于第二流量范围内的数据流量，为了便于描述，将数据流量位于第一流量范围的站点设备称为大流量设备，将数据流量位于第二流量范围的站点设备称为小流量设备。示例的，第一流量范围和第二流量范围可以通过流量阈值进行划分，大于(或者不小于)该流量阈值的数据流量位于第一流量范围，而不大于(或者小于)该流量阈值的数据流量位于第二流量范围，即流量阈值为第一流量范围中的最小值，以及第二流量范围中的最大值。本申请实施例中对第一流量范围和第二流量范围不做限定。
策略4：数据流量位于第二流量范围的至少一个站点设备位于一个站点设备组，也就是说，时间片是为数据流量位于第二流量范围的至少一个站点设备分配的。
在该策略4中，接入点设备将数据流量为第二流量范围的至少一个站点设备划分到一个组。
策略5：丢包率位于第一丢包范围的一个站点设备单独位于一个站点设备组，也就是说，时间片时为丢包率位于第一丢包范围的一个站点设备单独分配的。
在该策略5中，接入点设备将丢包率位于第一丢包范围的一个站点设备单独划分到一个组。
丢包范围可以包括但不限于第一丢包范围和第二丢包范围，其中第一丢包范围中的最小值大于或等于第二丢包范围的最大值，也就是说，位于第一丢包范围内的丢包率大于或等于位于第二丢包范围内的丢包率，为了便于描述，将丢包率位于第一丢包范围的站点设备称为高丢包率的站点设备，将丢包率位于第二丢包范围的站点设备称为低丢包率的站点设备。示例的，第一丢包范围和第二丢包范围可以通过丢包阈值进行划分，大于(或者不小于)该丢包阈值的丢包率位于第一丢包范围，而不大于(或者小于)该丢包阈值的丢包率位于第二丢包范围，即丢包阈值为第一丢包范围中的最小值，以及第二丢包范围中的最大值。本申请实施例对第一丢包范围和第二丢包范围不做限定。
策略6：丢包率位于第二丢包范围的至少一个站点设备位于一个站点设备组，也就是说，时间片是为丢包率位于第二丢包范围的至少一个站点设备分配的。
可选地，在上述各策略不冲突的情况下，上述策略之间可以结合使用，例如策略1、策略4和策略6中的多个之间可以结合使用。例如策略1和策略4结合使用时，位置信息属于同一房间，且数据流量位于第二流量范围的至少一个站点设备位于一个站点设备组。
可选地，上述策略1至策略6之间存在不同的优先级，例如但不限于：策略2的优先级＝策略3的优先级＝策略5的优先级＞策略1的优先级＝策略3的优先级＝策略6的优先级。
一种可能的实现中，接入点设备为每个站点设备(或每组站点设备)分配对应的时间片时，可以为每个站点设备(或每组站点设备)依次分配空口时隙(slot)。例如接入点设备为5个站点设备(或5组站点设备)分配时间片时，可以分配第n个slot的第1个时间片(用slotn+1表示)、第n个slot的第2个时间片(用slotn+2表示)、第n个slot的第3个时间片(用slotn+3表示)、第n个slot的第4个时间片(用slotn+4表示)、第n个slot的第5个时间片(用slotn+5表示)。通过时间片的分配，可以保证每个站点设备(或 每组站点设备)在属于自己的时间片发送数据包，可以避开隐藏节点，降低冲突的概率，提高Wi-Fi性能和可靠性。
可选地，接入点设备周期性地获取站点设备的站点信息，周期性地根据站点设备的站点信息，为站点设备更新时间片的信息。示例的，接入点设备定期向站点设备发送指令，指示站点设备反馈站点信息(如数据流量和/或丢包率等)。例如对于持续处于小流量的站点设备，接入点设备会分配更少的时间片，同理，对于流量增大的站点设备，接入点设备会分配更多的时间片。又如对于丢包率高的站点设备，可以尝试将该站点设备单独分到一个组中，通过为其分配单独的时间片，来检测丢包率是否得到改善。也就是说，接入点设备可以结合站点设备的站点信息，动态调整时间片，从而进一步减少空口竞争冲突。
下面结合家居场景和配网设备配置的过程，对本申请实施例进行详细说明。可以理解的是，对于Wi-Fi网络下的其它场景(例如但不限于办公场景、学校场景)，本申请实施例同样适用。家居场景的示意图如图5所示，AP包括路由器，STA包括STA1(手机)、STA2(台灯)、STA3(空调)、STA4(冰箱)、STA5(台式机)和STA6(电视机)。该家居场景中还包括配网设备，例如配网设备为手机。多个STA连接AP，STA之间因为距离、墙壁等因素可能出现隐藏节点，并且由于各STA和AP都有数据交互，因此可能存在空口竞争冲突的情况，而通过如下流程可以减少空口竞争冲突。
配网设备中安装有配网软件，配网软件提供编辑户型功能，编辑户型功能的用户界面600可以如图6所示，用户界面600可以包括楼层编辑图标601，户型显示区域602，户型编辑图标603和保存图标604。例如配网设备可以响应于用户对楼层编辑图标601的操作，对楼层进行编辑，楼层编辑图标601处显示有每层户型缩略图。又如配网设备可以响应于用户对户型编辑图标603的操作，对户型图进行编辑，如用户可以基于家庭的户型，对“添加房间图标”或“户型图标”进行操作编辑户型图，或者用户对“清空图标”或“重置图标”进行操作对户型显示区域602中显示的户型进行清空或重置。又如配网设备可以响应于对保存图标604的操作，对编辑的户型图进行保存。
用户编辑户型图后，配网设备可以提示编辑各设备位置(即设置设备所在的房间)，设备位置编辑的用户界面700如图7所示，用户通过在用户界面700选择设备所在房间，如配网设备响应于用户对“客厅图标”的操作，确定当前设备位于客厅。此外，用户界面700还包括添加房间图标701，配网设备可以响应于用户对添加房间图标701的操作，添加设备所在房间的选项。通过用户的多次操作，可以在户型图中设置AP和STA1～STA6的位置，例如设置设备位置后的户型图如图8所示，根据图8便可以知道当前用户家中拥有的设备，以及每个设备所在房间。
如图9所示，配网设备还提供有AP(路由器)信息的用户界面900，用户界面900包括户型图显示区域901，网络环境显示区域902，网络速率显示界面903，接入设备显示界面904和智能检测图标905。其中，户型图显示区域901中显示有户型图，以及户型图中每个房间接入该路由器的在线设备的数量。接入设备显示界面904显示有接入该路由器的在线设备的总数量。配网设备可以响应于用户对于智能检测图标905的操作，对该户型图中接入该路由器的设备进行智能检测。
各STA或配网设备可以将STA1～STA6的站点信息发送给AP，AP便可以获取到STA1～STA6的站点信息。STA1～STA6的站点信息，其中STA1～STA6的站点信息如下述表1所示STA1(手机)由于是移动设备，可以认为所在房间不固定，因此用不可用(not available，NA)表示。
表1
AP结合上述表1中的站点信息，可以对STA1～STA6进行分组(group)，其中在分组策略中，将移动设备单独分到一个组，这是因为移动设备位置可能会经常发生变化，若将移动设备与其他非移动设备分到一组，会导致隐藏节点信息发生变化或失效，空口竞争冲突；在分组策略中，将大流量站点设备单 独分一个组，这样可以避免大流量站点设备与其他站点之间出现空口竞争冲突；以及在分组策略中，将同一房间内的小流量站点设备分到一个组，这是因为通常在一个房间内的站点设备不会出现隐藏节点，也不会出现空口竞争冲突的问题。AP的分组结果如下述表2所示。
表2
AP将空口分成如图10所示的若干时间片，然后将时间片依次分配给每个组。其中每组站点设备与时间片的对应关系如下述表3所示。
表3
AP将每组站点设备对应的时间片信息发送给该组内的站点设备，这样每个分组的STA只在属于自己的时间片发送数据包，避免存在隐藏节点，同时可以降低空口竞争的冲突概率。
在完成一次分组之后，AP可以定期发送指令(在本申请实施例中不做限制)，指示STA反馈流量大小、丢包率等信息，AP会结合STA的各类站点信息，动态调整时间片。例如对于持续处于小流量状态的STA，表示该STA为小流量STA，AP可以在上次分配时间片的基础上，分配更少的时间片，同理对于流量增大的STA，AP可以在上次分配时间片的基础上，分配更多的时间片；而对于丢包率高(例如丢包率高于丢包率阈值，此处对丢包率阈值的取值不做限制)的STA，AP可以尝试将该STA单独分到一个组中，检测该STA的丢包率是否可以得到改善。
在本申请实施例中，配网设备通过配置STA的位置信息，可以使得整个网络可以避开隐藏节点，并且AP结合STA的设备类型、流量需求等站点信息分配时间片，而不是需要额外发送探测帧进行隐藏节点的探测，可以减少隐藏节点和空口竞争，减少丢包，提升网络性能和资源利用率。
由上述实施例可知，本申请实施例适用于图11所示的系统示意图，包括配网设备、AP和STA。其中配网设备中安装有配网软件，可以提供如上述图6～图9的功能。配网设备可以将配置的STA的位置信息发送给STA的信息封装模块，STA的信息封装模块通过通信模块向AP发送STA的站点信息(包括STA的位置信息)，AP的信息解析模块通过通信模块接收STA的站点信息，并将STA的站点信息解析后传输给AP的分组决策模块，分组决策模块指定分组策略以及为STA分配相应的时间片，然后通过通信模块将时间片的信息发送给STA，STA通过通信模块接收时间片的信息，且STA的分组执行模块按照该时间片发送数据包。
可以理解的是，图11所示的结构并不构成对配网设备、AP以及STA的具体限定。比如，在本申请另一些实施例中，配网设备、AP以及STA点可以包括比图示更多或更少的部件，或者组合某些部件，或者拆分某些部件，或者不同的部件布置。图示的部件可以以硬件，软件或软件和硬件的组合实现。例如AP中包括收发器和处理器，收发器可以实现通信模块的功能，处理器可以实现信息解析模块和分组决策模块的功能。又如STA中包括收发器和处理器，收发器可以实现通信模块的功能，处理器可以实现信息封装模块和分组执行模块的功能。
可以理解的，本申请实施例中，接入点设备和/或站点设备可以执行本申请实施例中的部分或全部步骤，这些步骤或操作仅是示例，本申请实施例还可以执行其它操作或者各种操作的变形。此外，各个步骤可以按照本申请实施例呈现的不同的顺序来执行，并且有可能并非要执行本申请实施例中的全部操作。
上述本申请提供的实施例中，分别从接入点设备和站点设备之间交互的角度对本申请实施例提供的方法进行了介绍。为了实现上述本申请实施例提供的方法中的各功能，接入点设备和站点设备可以包括硬件结构和/或软件模块，以硬件结构、软件模块、或硬件结构加软件模块的形式来实现上述各功能。上述各功能中的某个功能以硬件结构、软件模块、还是硬件结构加软件模块的方式来执行，取决于技术方案的特定应用和设计约束条件。
