应理解，本文中术语“***”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
现有技术中，为了提供传输可靠性，PDCP层可以将数据进行复制，具体的，PDCP层的PDCP分离承载(split bearer)复制功能(Duplication Function)可以将PDCP 业务数据单元(Service Data Unit，SDU)进行复制，得到多个PDCP PDU，该多个PDCP PDU具有相同的数据（payload）和相同的包头(header)，每一个PDCP PDU都可以称为复制数据。所述多个PDCP PDU，可以通过多个逻辑信道承载，但是MAC层不知道通过所述多个逻辑信道传输的数据为复制数据，即同一个数据，因此，进行数据调度时，MAC层不会考虑将所述多个逻辑信道中的数据调度到不同的载波上传输，因此，不能获得频率分集增益。
有鉴于此，本申请实施例提出一种传输数据的方法，能够将通过多个逻辑信道传输的复制数据，至少调度到两个不同的载波上传输，从而能够获得频率分集增益，进而提高传输数据的可靠性。
图2是根据本申请实施例的传输数据的方法200的示意性流程图。所述方法200可以由图1所述的通信***100中的终端设备120或网络设备110执行。如图2所示，该方法200包括以下内容。
S210，根据用于承载复制数据的多个逻辑信道，确定用于传输所述复制数据的多个载波或载波组，所述多个逻辑信道中至少两个逻辑信道对应的用于传输所述复制数据的载波或载波组不同；
S220，使用所述多个载波或载波组分别传输所述多个逻辑信道中承载的所述复制数据。
以下，以传输数据的设备为执行主体来描述本申请实施例的方法200，所述传输数据的设备可以为终端设备，也可以为网络设备。
因此，本申请实施例中，传输数据的设备可以根据承载复制数据的多个逻辑信道，确定多个载波或载波组，其中，所述多个逻辑信道中的至少两个逻辑信道对应的用于传输所述复制数据的载波或载波组不同，因此能够通过至少两个不同的载波或载波组传输所述复制数据，从而能够获得频率分集增益，进而能够提高传输可靠性。
具体而言，所述传输数据的设备在PDCP层可以生成多个复制数据，所述多个复制数据相同，所述多个复制数据可以通过多个逻辑信道传输，即每个逻辑信道可以承载一个复制数据。所述传输数据的设备可以根据所述多个逻辑信道，确定多个载波或载波组。在一种可能的实现方式中，逻辑信道和载波或载波组可以具有对应关系，从而所述传输数据的设备可以根据承载所述复制数据的多个逻辑信道，以及所述对应关系，确定对应的多个载波或载波组。可选地，所述对应关系可以是协议约定的，或者若所述传输数据的设备为终端设备，所述对应关系可以是网络设备通过高层信令发送给所述终端设备的，可选地，所述高层信令可以为无线资源控制(Radio Resource Control，RRC)信令。
可选地，在一些实施例中，逻辑信道可以和MAC实体具有对应关系，例如，不同的逻辑信道可以对应不同的MAC实体，而不同的MAC实体可以对应不同的物理层载波或载波组，从而所述传输数据的设备可以根据承载所述复制数据的所述多个逻辑信道，以及逻辑信道和MAC实体的对应关系，确定所述多个逻辑信道对应的多个MAC实体，进一步可以确定所述多个MAC实体对应的多个载波或载波组，由于不同的MAC实体对应的载波或载波组不同，因此，所述多个载波或载波组也不同。可选地，所述逻辑信道和MAC实体的对应关系可以是协议约定的，或者若所述传输数据的设备为终端设备，所述对应关系可以是网络设备通过高层信令配置给所述终端设备的，可选地，所述高层信令可以为RRC信令。
可选地，所述传输数据的设备还可以根据所述多个逻辑信道对应的指示信息，确定多个载波或载波组，例如，所述指示信息可以直接指示用于传输对应的逻辑信道中的复制数据的载波或载波组的标识(Identify，ID)，因此传输数据的设备在MAC层获取每个逻辑信道中的复制数据之后，可以根据所述每个逻辑信道对应的指示信息，确定每个指示信息指示的载波或载波组的ID。可选地，所述多个逻辑信道中的第一逻辑信道对应的指示信息还可以指示所述多个逻辑信道中除所述第一逻辑信道以外的其他逻辑信道的标识信息，从而传输数据的设备可以根据所述第一逻辑信道对应的指示信息，确定与所述第一逻辑信道共同传输复制数据的其他逻辑信道，从而所述传输数据的设备在MAC层调度数据时，可以将所述第一逻辑信道和所述其他逻辑信道中承载的复制数据调度到不同的载波或载波组上传输，从而能够获得频率分集增益，进而提高传输可靠性。
可选地，在一些实施例中，所述根据用于承载复制数据的多个逻辑信道，确定用于传输所述复制数据的多个载波或载波组，包括：
根据所述多个逻辑信道中的每个逻辑信道对应的指示信息，确定所述多个载波或载波组。
具体而言，用于承载复制数据的多个逻辑信道可以都对应相应的指示信息，所述传输数据的设备可以根据所述指示信息，确定用于传输所述多个逻辑信道中承载的复制数据的多个载波或载波组。可选地，所述每个逻辑信道对应的指示信息可以包括在所述每个逻辑信道对应的逻辑信道配置（LogicalChannelConfig）信息中，具体的，所述每个逻辑信道对应的逻辑信道配置信息可以为所述每个逻辑信道的RRC信息单元（RRC Information Element），所述RRC信息单元用于配置所述每个逻辑信道的信道参数，例如，逻辑信道调度优先级、所属的逻辑信道组等信息。
可选地，可以在每个逻辑信道对应的逻辑信道配置信息中新增一个指示域，用于承载所述指示信息，或者可以复用原有的指示域来承载所述指示信息，或者也可以利用所述逻辑信道配置信息中的预留域来承载所述指示信息。可选地，所述每个逻辑信道对应的指示信息也可以包括在所述每个逻辑信道的其他属性信息中，本申请实施例对此不作限定。
可选地，作为一个实施例，所述指示信息包括所述多个逻辑信道中的第一逻辑信道对应的第一指示信息，所述第一指示信息用于指示一个或一组载波的载波标识ID，所述根据所述多个逻辑信道中的每个逻辑信道对应的指示信息，确定所述多个载波或载波组，包括：
确定所述第一指示信息指示的一个载波的载波ID对应的第一载波或一组载波的载波ID对应的第一载波组为传输所述第一逻辑信道中承载的所述复制数据的载波或载波组；
所述使用所述多个载波或载波组分别传输所述多个逻辑信道中承载的所述复制数据，包括：
使用所述第一载波，或所述第一载波组中的部分或全部载波传输所述第一逻辑信道中承载的所述复制数据。
具体而言，每个逻辑信道的指示信息可以指示用于传输所述每个逻辑信道中承载的复制数据的载波或载波组的ID，例如，所述多个逻辑信道包括第一逻辑信道，所述第一逻辑信道对应的指示信息，为便于区分和描述，记为第一指示信息，所述第一指示信息可以指示一个或一组载波的载波ID，也就是说所述第一指示信息可以指示一个或多个载波的载波ID，所述一个或一组载波的载波ID对应的载波或载波组可以用于传输所述第一逻辑信道中承载的复制数据。也就是说，可以通过所述每个逻辑信道对应的指示信息指示用于传输所述每个逻辑信道中承载的复制数据的载波或载波组，因此，可以通过配置所述多个逻辑信道中至少两个逻辑信道对应的用于传输所述复制数据的载波或载波组不同，即至少两个逻辑信道对应的指示信息指示的载波或载波组不同，从而传输数据的设备可以将所述多个逻辑信道中承载的复制数据调度到至少两个不同的载波或载波组上传输。例如，所述多个逻辑信道包括逻辑信道1和逻辑信道2，分别对应指示信息1和指示信息2，所述指示信息1指示载波ID1，载波ID1对应载波1，所述指示信息2指示载波ID2，载波ID2对应载波2，从而逻辑信道1和逻辑信道2中承载的复制数据可以分别通过载波1和载波2传输，因此，传输数据的设备通过不同的载波传输复制数据，从而能够获得频率分集增益，进而提高传输数据的可靠性。
因此，所述传输数据的设备可以根据所述每个逻辑信道对应的指示信息，确定用于传输每个逻辑信道中承载的复制数据的载波或载波组，从而可以在所述每个逻辑信道对应的用于传输所述复制数据的载波或载波组上传输所述每个逻辑信道中承载的复制数据。具体的，若所述多个逻辑信道包括第一逻辑信道，所述第一逻辑信道对应的第一指示信息指示一个载波的载波ID，所述传输数据的设备可以使用所述第一指示信息指示的载波ID对应的载波传输所述第一逻辑信道中承载的复制数据，或者若所述第一指示信息指示一组载波的载波ID，所述传输数据的设备可以使用所述一组载波的载波ID对应的第一载波组中的部分或全部载波传输所述第一逻辑信道中承载的复制数据。应理解，在本申请实施例中，一组载波的载波ID可以为一个载波组的组ID，或者也可以为多个载波的载波ID，本申请实施例对此不作限定。
应理解，在本申请实施例中，所述多个逻辑信道分别对应的指示信息可以都指示一个载波的载波ID，也可以都指示一组载波的载波ID，或者一部分逻辑信道对应的指示信息指示一个载波的载波ID，其他的逻辑信道对应的指示信息指示一组载波的载波ID。此情况下，只需所述多个逻辑信道中的至少两个逻辑信道对应的指示信息指示的载波或载波组不同即可，从而传输数据的设备可以将所述复制数据调度到不同的载波或载波组上传输。
可选地，在一些实施例中，所述指示信息包括所述多个逻辑信道中的第二逻辑信道对应的第二指示信息，所述第二指示信息为所述多个逻辑信道中除所述第二逻辑信道以外的其他逻辑信道的标识信息，所述根据所述多个逻辑信道中的每个逻辑信道对应的指示信息，确定所述多个载波或载波组，包括：
根据所述第二指示信息，确定所述第二逻辑信道和所述其他逻辑信道中承载的所述复制数据分别对应不同的载波或载波组；
所述使用所述多个载波或载波组分别传输所述多个逻辑信道中承载的所述复制数据，包括：
使用所述不同的载波或载波组分别传输所述第二逻辑信道和所述其他逻辑信道中承载的所述复制数据。
具体的，所述多个逻辑信道中可以包括第二逻辑信道，所述第二逻辑信道对应的指示信息，为便于区分和描述，记为第二指示信息，所述第二指示信息可以指示所述多个逻辑信道中除所述第二逻辑信道以外的其他逻辑信道的标识信息，因此，所述传输数据的设备可以根据所述第二指示信息，确定哪些逻辑信道中传输了复制数据，从而可以在MAC层可以将这些逻辑信道中承载的复制数据调度到不同的载波上传输，因而能够获得频率分集增益，进而提高了传输数据的可靠性。例如，所述多个逻辑信道包括逻辑信道1和逻辑信道2，分别对应的逻辑信道标识为LC1和LC2，那么逻辑信道1对应的指示信息可以指示LC2，逻辑信道2对应的指示信息可以指示LC1，从而传输数据的设备可以获知这两个逻辑信道是用来传输复制数据的，进而可以将这两个逻辑信道中的复制数据调度到不同的载波上传输，因此能够获得频率分集增益，进一步提高了传输可靠性。
也就是说，每个逻辑信道对应的指示信息可以直接指示用于传输所述每个逻辑信道中承载的复数数据的载波或载波组，从而传输数据的设备可以直接根据每个逻辑信道的指示信息指示的载波或载波组调度所述每个逻辑信道中承载的复制数据。或者所述每个逻辑信道对应的指示信息也可以指示与所述每个逻辑信道共同传输复制数据的逻辑信道的标识信息，从而传输数据的设备可以在MAC层确定将所述每个逻辑信道中承载的复制数据调度到哪些不同的载波或载波组上传输。
可选地，在一些实施例中，所述指示信息包括所述多个逻辑信道中的第三逻辑信道对应的第三指示信息，所述第三指示信息用于指示所述第三逻辑信道中是否承载所述复制数据，所述根据所述多个逻辑信道中的每个逻辑信道对应的指示信息，确定所述多个载波或载波组，包括：

所述使用所述多个载波或载波组分别传输所述多个逻辑信道中承载的所述复制数据，包括：
使用所述不同的载波或载波组分别传输所述第三逻辑信道和所述第四逻辑信道中承载的所述复制数据。
具体的，所述多个逻辑信道中可以包括第三逻辑信道，所述第三逻辑信道对应的指示信息，为便于区分和描述，记为第三指示信息，所述第三指示信息可以指示所述第三逻辑信道是否承载所述复制数据，第四逻辑信道对应的指示信息也可以指示所述第四逻辑信道是否承载所述复制数据，若所述传输数据的设备确定第三指示信息指示承载复制数据，同时第四逻辑信道对应的指示信息也指示承载复制数据，那么所述传输数据的设备可以将所述第三逻辑信道和所述第四逻辑信道中承载的复制数据调度到不同的载波上传输，因此能够获得频率分集增益，进一步提高了传输可靠性。
可选地，在一些实施例中，在所述根据所述多个逻辑信道中的每个逻辑信道对应的指示信息，确定所述多个载波或载波组之前，所述方法还包括：
确定所述每个逻辑信道的逻辑信道配置信息中存在包括所述指示信息的指示域。
具体的，在MAC层，所述传输数据的设备可以首先确定所述每个逻辑信道对应的逻辑信道配置信息中是否存在用于承载所述指示信息的指示域，若存在所述指示域，所述传输数据的设备可以根据上述实施例中描述的方法，将所述多个逻辑信道中承载的复数数据调度到不同的载波或载波组中传输，否则，所述传输数据的设备可以按照现有技术中的调度方法对所述多个逻辑信道中承载的数据进行调度。
可选地，在一些实施例中，所述根据用于承载复制数据的多个逻辑信道，确定用于传输所述复制数据的多个载波或载波组，包括：
根据所述多个逻辑信道，以及第一对应关系，确定多个媒体接入控制MAC实体，所述第一对应关系为逻辑信道与MAC实体的对应关系，所述多个逻辑信道和所述多个MAC实体一一对应；
根据所述多个MAC实体，以及第二对应关系，确定所述多个载波或载波组，所述第二对应关系为MAC实体和载波或载波组的对应关系，所述多个MAC实体和所述多个载波或载波组一一对应。
具体而言，逻辑信道和MAC实体可以具有第一对应关系，所述第一对应关系可以是一对一的对应关系，即逻辑信道和MAC实体是一一对应的，因此，所述传输数据的设备可以根据所述多个逻辑信道，以及所述第一对应关系，确定多个MAC实体，而不同的MAC实体对应不同的载波或载波组，即MAC实体和载波或载波组可以具有第二对应关系，所述第二对应关系可以是一对一的对应关系，也可以是一对多的对应关系，即一个MAC实体可以对应一个载波或载波组，或一个MAC实体可以对应多个载波或载波组。从而所述传输数据的设备可以根据所述多个MAC实体，以及第二对应关系，确定多个载波或载波组，之后所述传输数据的设备可以通过所述多个载波或载波组传输所述多个逻辑信道中承载的复制数据。
可选地，在一些实施例中，所述第一对应关系是通过高层信令预配置的。
具体的，若所述传输数据的设备为终端设备，所述第一对应关系可以是网络设备通过高层信令预配置给所述终端设备的，或者所述第一对应关系也可以是终端设备和网络设备约定好的，或者，所述第一对应关系也可以是协议规定的。若所述传输数据的设备为网络设备，所述第一对应关系可以是所述网络设备预配置的，或者是所述网络设备和所述终端设备约定好的，或者，所述第一对应关系可以是协议规定的。
可选地，在本申请实施例中，所述复制数据是来自分组数据汇聚协议PDCP分离承载对同一个PDCP协议数据单元PDU的复制数据。
也就是说，所述复制数据可以是PDCP分离承载将同一个PDCP PDU复制为多个，每一个都可以称为复制数据，每个复制的PDCP PDU具有相同的内容，即相同的payload和header，在RLC层，将所述多个复制数据映射到多个逻辑信道上，也就是说，通过多个逻辑信道分别传输所述多个复制数据。
可选地，在一些实施例中，所述复制数据通过所述多个逻辑信道承载是通过高层信令预配置的。
也就是说，可以通过高层信令预配置可以通过哪些逻辑信道传输复制数据，那么在这些逻辑信道上有数据传输时，可以认为这些逻辑信道上传输的数据为复制数据，可选地，所述高层信令为RRC信令。
以下，结合具体示例，介绍本申请实施例的传输数据的方法，如图3所示，PDCP层的PDCP分离承载复制功能模块可以将PDCP SDU1复制为两个PDCP PDU1，所述两个PDCP PDU1包括相同的数据和包头，在RLC层，所述两个PDCP PDU1分别映射到RLC逻辑信道1和RLC逻辑信道2，一种可能的实现方式中，在每个逻辑信道的LogicalChannelConfig的RRC信息单元(information element)包括指示信息，所述指示信息指示载波ID，例如，所述RLC逻辑信道1对应的指示信息指示载波ID1，对应载波1，载波1对应MAC层的HARQ实体1，所述RLC逻辑信道2对应的指示信息指示载波ID2，对应载波2，载波2对应MAC层的HARQ实体2。从而传输数据的设备可以将这两个PDCP PDU1调度到载波1和载波2上传输。再如，所述RLC逻辑信道1对应的指示信息指示载波ID1、载波ID2和载波ID3，分别对应载波1、载波2和载波3，所述RLC逻辑信道2对应的指示信息指示载波ID4、载波ID5和载波ID6，对应载波4、载波5和载波6，从而传输数据的设备可以在载波1、载波2和载波3中选择传输RLC逻辑信道1中的PDCP PDU1的载波，即在载波1、载波2和载波3中的至少一个载波上传输所述RLC逻辑信道1中的PDCP PDU1，同样地，在载波4、载波5和载波6中选择传输RLC逻辑信道2中的PDCP PDU1的载波，即在载波4、载波5和载波6中的至少一个载波上传输所述RLC逻辑信道2中的PDCP PDU1。
可选地，在另一种可能的实现方式中，每个逻辑信道的指示信息指示逻辑信道的ID，对于图3中的RLC逻辑信道1的指示信息可以指示LC2，对于RCL逻辑信道2，RLC逻辑信道2的指示信息可以指示LC1，对于RCL逻辑信道1，即RLC逻辑信道1和RLC逻辑信道2是用来传输复制数据的，从而传输数据的设备可以将RLC逻辑信道1和RCL逻辑信道2中承载的复制数据调度到不同的载波上传输，例如，可以将RLC逻辑信道1和RCL逻辑信道2中承载的复制数据分别调度到载波1和载波2上传输。
