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。
图1示出的是本公开一个示意性实施例提供的通信系统的框图，如图1所示，该通信系统可以包括：接入网12和终端13。
接入网12中包括若干接入网设备120。接入网设备120可以是基站，基站是一种部署在接入网中用以为终端提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，在5G新空口(NR，New Radio)系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称可能描述，会变化，例如在5G后续演进的各项技术的网络中基站也可以采用其他名称。为方便描述，下文中将上述为终端提供无线通信功能的装置统称为接入网设备。
终端13可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备(例如，传感器)，以及各种形式的用户设备，移动台(Mobile Station，MS)，终端等等。为方便描述，上面提到的设备统称为终端。接入网设备120与终端13之间通过某种空口技术互相通信，例如Uu接口。
如前所述，基于涡旋波的特性可以大幅扩大传输容量，实现5G后续演进的 各项技术的通信。由于传输容量的扩大，5G后续演进的各项技术的应用也将简单的互联互通扩展为智慧互连，智慧互连包括多传感器数据融合，以实现数字孪生的前景目标。多传感器数据融合中包括多种形态的传感器(多模态)数据的传输，例如视觉、听觉、触觉、光电等传感器信息的传输和融合。
在进行多种形态的传感器数据的融合时，各个传感器数据的时序是推导其事件逻辑的关键环节。例如在医疗应用中，脑电传感器数据、肌电传感器数据与运动传感器数据(跌倒等)的时间顺序成为了诊断的重要依据，如医生需要基于各个传感器数据的时序先后，判断是脑电异常导致痉挛(肌电反应)，从而跌倒；还是跌倒造成的肌电异常，从而形成脑电异常。
相关技术中，通常是在数据中打入时间戳来表明数据采集的时间，当传输很密集时，需要消耗大量的信令开销来承载时间戳信息。而如果不使用时间戳，传感器本身的传输能力不同，会存在后发先至的情况，造成无法基于接收到的时间准确判断出时序先后。
本公开实施例描述的通信系统以及业务场景是为了更加清楚地说明本公开实施例的技术方案，并不构成对本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着通信系统的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
图2是根据一示例性实施例示出的一种通信方法的流程图。参见图2，该方法包括以下步骤：
在步骤101中，接入网设备接收至少两个信道的传输。
在本公开的所有实施例中，信道的传输(Transmission)可以为以下的任一种：数据、信令、数据和信令混合传输；即信道的传输可以为信道传输的数据、信令、数据和信令混合等。本公开后续以数据为例进行说明。值得说明的是，本申请中“传输”一词除了表示上述名词外，还用作动词，例如“传输数据”、“进行传输”等词组中，“传输”一词表示传输的动作。
这里，至少两个信道对应至少两个设备，也即由至少两个设备通过至少两个信道向接入网设备传输数据。这里的设备是指终端，例如传感器等。
在步骤102中，接入网设备确定所述至少两个信道的传输的顺序。
在该步骤中，可以基于信道的优先级高低对至少两个信道的传输排序。示例性地，可以将每个信道对于的时间划分为多个连续的时间窗口。将在一组时 间窗口内从所述至少两个信道接收到的数据，按照所述至少两个信道的优先级排序，所述一组时间窗口是指与所述至少两个信道一一对应的至少两个时间窗口。
通常，一组时间窗口中的与各个信道对应的时间窗口的序号相同。例如，在信道A的第一时间窗口从信道A中接收到数据A，在信道B的第一时间窗口从信道B接收到数据B。若信道A的优先级高于信道B，则将数据A排在数据B之前。需要说明的是，虽然数据A和数据B都是在第一时间窗口中接收到的，但实际接收时间并不一定是数据A在数据B之前，只要二者都在第一时间窗口内接收，且信道A的优先级高于信道B，则将数据A排在数据B之前。
两个信道的优先级可以相同，也可以不同。当两个信道优先级不同时，按照高低进行数据排序，当两个信道优先级相同时，则对应的数据顺序相同。
在步骤103中，接入网设备根据所述至少两个信道的传输的顺序，对接收到的所述至少两个信道的传输进行处理。
例如，数据A的顺序在数据B之前，则先解析数据A再解析数据B。这里的解析包括但不限于数据解码和数据输出等，例如先对医用传感器的数据进行解码，得到后端处理设备可以处理的数据，然后将解码后的数据传输给后端处理设备，后端处理设备利用解码后的数据进行诊断。
在本公开实施例中，先确定从所述至少两个信道接收到的传输的顺序，然后根据至少两个信道的传输的顺序，对至少两个信道的传输进行处理。不再基于传输接收到的先后或者携带的时间戳来确定处理的顺序。在不采用时间戳前提下，也无需按照接收到的先后进行处理，即可在实现低时延的时序数据传输的同时不增加信令开销。
可选地，所述至少两个信道为频率相同、相位偏移不同的涡旋波信道；
或者，所述至少两个信道为频率不同的信道。
在该实现方式中，既可以采用不同频率的信号，也可以采用相同频率的信号。其中，相同频率信号是利用不同相位偏移的涡旋波在同频下可以同时传输的特性，从而同时或者接近同时的传输带有时序逻辑的业务数据，采用同频的涡旋波信道传输数据，频率资源消耗少。
可选地，所述确定所述至少两个信道的传输的顺序，包括：
将一组时间窗口内从所述至少两个信道接收到的传输，按照所述至少两个信道的顺序对接收到的传输进行排序；
其中，所述一组时间窗口是指与所述至少两个信道一一对应的至少两个时间窗口。
在本公开实施例中，通过将在一组时间窗口内从所述至少两个信道接收到的数据，按照至少两个信道的优先级排序，然后进行解析。例如，可以将一组时间窗口内接收到的优先级高的信道传输的数据排在优先级低的信号传输的数据之前。由于时间窗口可以根据终端的能力和业务需求设定，保证每个时间窗口内接收到一个信道的一个数据，然后根据终端的能力进行信道优先级的划分，从而可以让数据解析的顺序按照数据采集的先后进行，而无需设置时间戳。也即，在不采用时间戳进行数据同时传输的前提下，不同信道的数据解析的顺序是按照数据采集的先后进行的，在实现低时延的时序数据传输的同时不增加信令开销。
可选地，每个所述信道对应多个连续且周期性的时间窗口。
时间窗口是连续且周期性设置的。一组时间窗口对应的周期数相同，周期数相同的时间窗口内接收到的数据才会比较优先级。而不同周期内的数据，总是按照在前周期接收到的数据在在后周期接收到的数据之前来排序。
可选地，每个所述信道的第一个所述时间窗口是以标准时间作为基准时间的标准时间窗口，或者每个所述信道的第一个所述时间窗口是以所述信道接收到第一个数据的时间作为基准时间的相对时间窗口。
这里标准时间可以是指世界标准时间(Coordinated Universal Time，UTC)，也可以是某个时区的标准时间，例如北京时间等。该标准时间也可以是系统定义的标准时间，例如以某一时刻为0时刻，定义出的一个时间。该标准时间也可以是按照系统帧结构的组成单元计数得到的时间，例如第多少个符号对应的时间。
相对时间则是以指定的一个时间发生的时间作为基准，例如所有信道中第一个接收到数据的信道接收到第一个数据的时间，所有的时间窗口均以此为基准选定。
可选地，任意两个所述信道的第一个所述时间窗口的基准时间相同或不同。
下面结合图3到图6对时间窗口的划分方式进行举例说明：
图3是本公开实施例提供的一种时间窗口的示意图。参见图3，信道A和信道B的第一个时间窗口的基准时间相同，且信道A和信道B的第一个时间窗口的基准时间可以是标准时间。例如，系统定义的第100分钟，则从系统定义 的第100分钟开始进行第一个时间窗口的数据排序。
图4是本公开实施例提供的一种时间窗口的示意图。参见图4，信道A和信道B的第一个时间窗口的基准时间不同，且信道A和信道B的第一个时间窗口的基准时间可以是标准时间。
图5是本公开实施例提供的一种时间窗口的示意图。参见图5，信道A和信道B的第一个时间窗口的基准时间相同，且信道A和信道B的第一个时间窗口的基准时间可以是信道B接收到数据1的时间。
图6是本公开实施例提供的一种时间窗口的示意图。参见图6，信道A和信道B的第一个时间窗口的基准时间不同，且信道A的第一个时间窗口的基准时间可以是信道A接收到数据1的时间，信道B的第一个时间窗口的基准时间可以是信道B接收到数据1的时间。
可选地，所述按照所述至少两个信道的顺序对接收到的传输进行排序，包括：包括：
将在一组时间窗口内接收到的、优先级高的信道的数据排在优先级低的信道的数据之前。
可选地，所述按照所述至少两个信道的顺序对接收到的传输进行排序，包括：包括：
将在一组时间窗口内接收到的、优先级相同的两个信道的数据排在相同顺序。
当存在多个信道时，这些信道中可以既存在优先级高低不同的信道、也存在优先级相同的信道。
以图3为例，若信道A的优先级高于信道B，则两个信道的数据排序为信道A数据1、信道B数据1、信道A数据2、信道B数据2、信道A数据3、信道B数据3。若信道A的优先级等同于信道B，则信道A数据1和信道B数据1顺序相同，信道A数据2和信道B数据2顺序相同，信道A数据3和信道B数据3顺序相同，信道A中数据排序为数据1、数据2、数据3。
前面描述的信道优先级，是两个信道在各个时序窗口的优先级关系均相同。例如，信道A优先级高于信道B，则各个时序窗口均是信道A优先级高于信道B。
在其他实施例中，两个信道的优先级也可以按照不同时序窗口划分设定。例如，时序窗口1和2信道A的优先级高于信道B，时序窗口3信道B的优先 级高于信道A，则两个信道的数据排序为信道A数据1、信道B数据1、信道A数据2、信道B数据2、信道B数据3、信道A数据3。
需要说明的是，图3～图6中每个时间窗口都对应1个数据，当终端的处理和传输速度波动较大时，可能出现一个时间窗口内2个数据，一个时间窗口内没有数据的情况。若出现这种情况，则1个时间窗口内除了第一个数据依然按照信道优先级排序外，从第二个数据开始按照时间先后均排在下一个时间窗口的数据之前。
如图7所示，假设信道B的优先级高于信道A，则此时数据排序为信道B数据1、信道A数据1、信道A数据2、信道B数据2、信道B数据3、信道A数据3。
可选地，所述方法还包括：
获取配置信息，所述配置信息包括以下的至少一个参数：时间窗口基准时间；时间窗口长度；信道优先级。
该配置信息可以在接入网设备本地配置，例如通过接口配置或者配置在继而为设备的协议中。该配置信息也可以由核心网网元发送给接入网设备，例如由物理层信令、上层信令(媒体访问控制(Media Access Control，MAC)信令、无线资源控制(Radio Resource Control，RRC)信令)或者广播信令传输给接入网设备。
其中，核心网网元可以为移动管理节点功能实体(Mobility Management Entity function，MME)。
可选地，所述时间窗口长度与最大发送时长正相关，其中所述最大发送时长为每一所述信道发送数据所需的最大时长。
示例性地，所述至少两个信道对应至少两个设备，所述最大发送时长也即是所述至少两个设备发送一个所述数据所需的最大时长。
由于传感器本身的传输能力存在差异，例如传感器u相比于传感器v，传输能力强、带宽或多进多出(Multiple In Multiple Out，MIMO)能力强等等，若同时向接入网设备发送数据传感器u比传感器v平均提前0.1ms完成传输，此时可以基于传感器v传输一次数据所用的发送时长设定时间窗口。例如，采用传感器v传输一次数据所用的发送时长。
可选地，所述时间窗口长度与业务周期长度正相关，所述业务周期长度为所述数据对应的业务的周期时间长度。
例如，不同业务进行数据处理的业务周期长度不同，也即业务对时序颗粒度的要求不同，如普通医疗传感要求辨识10ms的逻辑时序，所以可以采用10ms作为时间窗口长度，车联网要求辨识1ms的逻辑时序，所以可以采用1ms作为时间窗口长度，工业控制和手术要求0.1ms的逻辑时序辨识，所以可以采用0.1ms作为时间窗口长度等。当然设定时间窗口长度时，不一定和业务周期长度完全相等，但时间窗口长度与业务周期长度存在正相关关系。
可选地，所述信道优先级与设备能力负相关，所述至少两个信道对应至少两个设备，所述设备能力为采用每一所述信道进行数据发送的设备的能力参数。
设备能力越强，传输速度越快，如果两个设备传输的数据在同一组时间窗口内被接收到，通常传输速度慢的一个先采集，也即传输速度慢的设备的数据的采集时间在前，这样，将传输速度慢的设备对应的信道优先级设定成高，使得在排序时，可以将传输速度慢的设备的数据排在前面，从而符合数据采集的先后。
可选地，所述方法还包括：
接收核心网网元发送的配置信令，所述配置信令用于指示启用或停用所述时间窗口。
本公开实施例提供的通信方法，可以通过核心网网元下发的配置信令进行开关，从而控制接入网设备是否利用时间窗口来进行数据的接收和处理。
示例性地，配置信令可以采用1个比特位确定时间窗口启用或停用，例如比特0表示启用，比特1表示停用。
另外，当配置信令指示启用时间窗口时，该配置信令中还可以同时携带前述配置信息。
可选地，所述接收核心网网元发送的配置信令，包括：
接收携带有所述配置信令的物理层信令、MAC信令、RRC信令或广播信令。
值得说明的是，前述步骤101～步骤103与上述可选步骤可以任意组合。
图8是根据一示例性实施例示出的一种通信方法的流程图。参见图8，该方法包括以下步骤：
步骤201：核心网网元向接入网设备发送配置信令。接入网设备接收该配置信令。
示例性地，该步骤可以包括：核心网网元向接入网设备发送携带有所述配 置信令的物理层信令、MAC信令、RRC信令或广播信令；接入网设备接收携带有所述配置信令的物理层信令、MAC信令、RRC信令或广播信令。
该配置信令用于指示启用或停用所述时间窗口。示例性地，配置信令可以采用1个比特位确定时间窗口启用或停用，例如比特0表示启用，比特1表示停用。
另外，当配置信令指示启用时间窗口时，该配置信令中还可以同时携带前述配置信息。所述配置信息包括时间窗口基准时间、时间窗口长度和信道优先级中的至少一个。
可选地，所述时间窗口长度与最大发送时长正相关，其中所述最大发送时长为每一所述信道发送数据所需的最大时长。
由于传感器本身的传输能力存在差异，例如传感器u相比于传感器v，传输能力强、带宽或多进多出能力强等等，若同时向接入网设备发送数据传感器u比传感器v平均提前0.1ms完成传输，此时可以基于传感器v传输一次数据所用的发送时长设定时间窗口。例如，采用传感器v传输一次数据所用的发送时长。
可选地，所述时间窗口长度与业务周期长度正相关，所述业务周期长度为所述数据对应的业务的周期时间长度。
例如，不同业务进行数据处理的业务周期长度不同，也即业务对时序颗粒度的要求不同，如普通医疗传感要求辨识10ms的逻辑时序，所以可以采用10ms作为时间窗口长度，车联网要求辨识1ms的逻辑时序，所以可以采用1ms作为时间窗口长度，工业控制和手术要求0.1ms的逻辑时序辨识，所以可以采用0.1ms作为时间窗口长度等。当然设定时间窗口长度时，不一定和业务周期长度完全相等，但时间窗口长度与业务周期长度存在正相关关系。
可选地，所述信道优先级与设备能力负相关，所述设备能力为采用每一所述信道进行数据发送的设备的能力参数。
设备能力越强，传输速度越快，如果两个设备传输的数据在同一组时间窗口内被接收到，通常传输速度慢的一个先采集，也即传输速度慢的设备的数据的采集时间在前，这样，将传输速度慢的设备对应的信道优先级设定成高，使得在排序时，可以将传输速度慢的设备的数据排在前面，从而符合数据采集的先后。
步骤202：接入网设备接收至少两个信道传输的数据。
这里，至少两个信道对应至少两个设备，也即由至少两个设备通过至少两 个信道向接入网设备传输数据。这里的设备是指终端，例如传感器等。
步骤203：接入网设备将在一组时间窗口内接收到的、优先级高的信道的数据排在优先级低的信道的数据之前，将在一组时间窗口内接收到的、优先级相同的两个信道的数据排在相同顺序。
以图3为例，若信道A的优先级高于信道B，则两个信道的数据排序为信道A数据1、信道B数据1、信道A数据2、信道B数据2、信道A数据3、信道B数据3。若信道A的优先级等同于信道B，则信道A数据1和信道B数据1顺序相同，信道A数据2和信道B数据2顺序相同，信道A数据3和信道B数据3顺序相同，信道A中数据排序为数据1、数据2、数据3。
需要说明的是，图3～图6中每个时间窗口都对应1个数据，当终端的处理和传输速度波动较大时，可能出现一个时间窗口内2个数据，一个时间窗口内没有数据的情况。若出现这种情况，则1个时间窗口内除了第一个数据依然按照信道优先级排序外，从第二个数据开始按照时间先后均排在下一个时间窗口的数据之前。
如图7所示，假设信道B的优先级高于信道A，则此时数据排序为信道B数据1、信道A数据1、信道A数据2、信道B数据2、信道B数据3、信道A数据3。
步骤204：接入网设备按照排序对接收到的所述数据进行处理。
例如，数据A的顺序在数据B之前，则先解析数据A再解析数据B。这里的解析包括但不限于数据解码和数据输出等，例如先对医用传感器的数据进行解码，得到后端处理设备可以处理的数据，然后将解码后的数据传输给后端处理设备，后端处理设备利用解码后的数据进行诊断。
