目前的无线通信系统中，若网络设备配置了跨载波调度，则终端设备只在调度载波上检测接收对应的DCI。也就是说，不同的载波上的数据通过不同的DCI进行调度。当网络设备使用同一DCI同时调度多个载波时，网络设备如何调度用于数据传输的一个或多个载波，目前并没有明确的方法。
基于此，本申请实施例提供一种数据传输方法，其中，终端设备可以根据第一指示信息所指示的第一载波组合来确定网络设备调度的一个或多个载波，并且，终端设备还可以通过第一DCI确定第一载波组合中每个载波对应的传输资源，也就是说，终端设备可以结合第一指示信息和第一DCI，确定当前调度的载波组合以及该载波组合至少一个载波对应的传输资源，并基于该传输资源进行数据传输，提高了载波调度的灵活性，并在一定程度上节省了信令开销。
为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
图2是本申请实施例提供的数据传输方法的流程示意图，如图2所示，该方法包括以下内容。
步骤210、终端设备接收网络设备发送的第一指示信息；其中，第一指示信息用于指示第一载波组合，所述第一载波组合为预配置的多个载波组合中的任意一个，第一载波组合中至少一个载波对应的传输资源通过第一DCI调度。
步骤220、终端设备通过第一载波组合中的至少一个载波对应的传输资源，与网络设备进行数据传输。
可选地，网络设备可以预先为终端设备配置多个载波。
可选地，网络设备可以通过高层信令或物理层信令为终端设备配置多个载波。这里，高层信令可以是无线资源控制(Radio Resource Control，RRC)连接建立消息、RRC重配置消息等，物理层信令可以为下行控制信息。本申请实施例对配置多个载波的方式不做限制。
可选地，上述多个载波可以被划分为多个载波组合，每个载波组合中可以包括至少一个载波。
示例性的，若网络设备可以为终端设备预配置7个载波，包括载波1至载波7。载 波1至载波7可以分为如下载波组合：{载波1、载波2}、{载波1、载波3}、{载波1、载波5}、{载波2、载波3}、{载波2、载波6}、{载波3、载波4}、{载波3、载波7}、{载波5、载波6、载波7}等。
需要说明的是，上述载波组合可以是网络设备为终端设备预先配置的，也可以是终端设备根据协议预定义的方式进行分组得到的，本申请实施例对此不做限制。
应理解，网络设备需要对终端设备的载波进行切换时，可以向终端设备发送第一指示信息，通过第一指示信息来指示当前调度的载波组合为多个载波组合中的第一载波组合。
可选地，网络设备设备可以根据实际的数据传输需求，或者终端设备的节能需求，通过第一指示信息为终端设备配置第一载波组合。
本申请实施例中，网络设备可以通过多种方式指示第一载波组合。
在一可行的示例中，第一指示信息可以是第一载波组合中每个载波的频点信息。例如，若网络设备需要调度载波1和载波3，则网络设备向终端设备发送的第一指示信息可以为载波1和载波3的频点信息。
在另一可行的示例中，第一指示信息可以是第一载波组合在预配置的多个载波组合的偏移量。例如，{载波1、载波2}的偏移量为0、{载波1、载波3}的偏移量为1、以此类推，{载波5、载波6、载波7}的偏移量为7。若网络设备需要调度载波1和载波3，则第一指示信息可以是1。
在又一可行的示例中，第一指示信息可以使用载波指示符(Carrier Indicator Feild，CIF)来指示第一载波组合。
需要说明的是，以上仅是对第一指示信息进行示例性说明，并不用于限定第一指示信息的指示方式。
可选地，第一指示信息所指示的第一载波组合中至少一个载波对应的传输资源，可以通过第一DCI来调度。
应理解，当第一载波组合中包括多个载波时，每个载波对应的传输资源均通过第一DCI调度。也就是说，第一DCI可以用于调度多个载波的传输资源。网络设备可以利用一个DCI来调度载波组合中多个载波分别对应的传输资源，可以在保证数据正确传输的基础上，降低信令开销。
需要说明的是，载波对应的传输资源可以包括时域资源、频域资源、空域资源中的至少一项，本申请实施例对此不做限制。
可选地，第一指示信息可以通过高层信令携带，或者通过上述第一DCI携带。本申请实施例对此不作限定。
示例性的，高层信令可以是RRC重配置信令，或者RRC连接建立信令等，也可以是新引入的、专用信令，本申请实施例对此不做限制。
应理解，终端设备通过第一指示信息确定网络设备指示的第一载波组合，并通过第一DCI确定第一指示信息所指示的第一载波组合中每个载波组合对应的传输资源，进而终端设备可以将当前调度的载波切换为第一载波组合中的一个或多个载波进行数据传输。也就是说，终端设备接收到第一指示信息所指示的第一载波组合后，在后续数据传输过程中，通过第一载波组合中的一个或多个载波对应的传输资源与网络设备进行数据传输。
本申请实施例提供的数据传输方法中，网络设备可以通过第一指示信息向终端设备指示后续所调度的载波组合，并通过第一DCI调度第一指示信息所指示的载波组合中每个载波对应的传输资源。相应的，终端设备可以根据第一指示信息和第一DCI确定网络设备使用的一个或多个载波，以及该一个或多个载波对应的传输资源，基于此，终端设 备可以结合第一指示信息和第一DCI确定网络设备所调度的一个或多个载波对应的传输资源，并基于该传输资源与网络设备进行数据传输。如此，通过第一指示信息来切换所调度的一个或多个载波，提高了载波调度的灵活性，并且通过第一DCI调度至少一个载波对应的传输资源，可以在一定程度上降低DCI的开销，提高载波的切换效率。
可选地，参考图3所示，步骤220中终端设备通过第一载波组合中的至少一个载波对应的传输资源与网络设备进行数据传输，还可以通过以下方式实现：
步骤2201、终端设备在接收到第一指示信息后的第一时间段内，通过第一载波组合中的至少一个载波对应的传输资源与网络设备进行数据传输。
应理解，本申请实施例中，网络设备可以通过第一指示信息半静态地为终端设备指示第一载波组合中的至少一个载波。具体地，终端设备在接收到第一指示信息之后的第一时间段内，第一DCI调度的均是第一载波组合中至少一个载波对应的传输资源。终端设备可以在第一时间段内通过第一DCI确定第一载波组合中每个载波对应的传输资源与网络设备进行数据传输。
由此可见，本申请实施例中网络设备和终端设备可以通过第一指示信息，约定在传输第一指示信息后的第一时间段内，持续使用第一指示信息所指示的第一载波组合进行数据传输。如何，避免网络设备频繁指示载波组合造成的信令风暴，降低了信令开销，提高了数据传输的效率。
可选地，第一时间段可以通过网络设备配置，或者，通过协议规定的预设参数确定，本申请实施例对此不做限制。
可选地，若第一时间段通过网络设备配置，则网络设备可以在步骤220’之前向终端设备发送第二指示信息，通过第二指示信息向终端设备配置第一时间段。
可选地，第二指示信息可以通过高层信令携带，或者，通过第二DCI携带。
其中，携带第二指示信息的高层信令可以是RRC重配置信令，或者RRC连接建立信令等，本申请实施例对此不做限制。
需要说明的是，携带第二指示信息的高层信令可以与携带第一指示信息的高层信令相同，也可以与携带第一指示信息的高层信令不同，本申请实施例对此不做限制。
还需要说明的是，第二DCI可以与第一DCI相同，也可以与第一DCI不同，本申请实施例对此不做限制。
可选地，在上述步骤2201的基础上，本申请实施例提供的数据传输方法，还可以包括以下步骤：
步骤230、第一时间段的结束时刻之后，终端设备通过第二载波组合中的至少一个载波进行数据传输；或者，第二载波组合为终端设备在接收第一指示信息之前使用的载波组合，
第一时间段的结束时刻之后，终端设备通过第三载波组合中的至少一个载波与网络设备进行数据传输，第三载波组合为特定载波组合。
需要说明的是，第三载波组合特定载波组合，也就是说，第三载波组合可以是固定的一个载波组合。实际应用中，终端设备与该网络设备建立通信连接后，可以默认通过特定载波组合中的一个或多个载波与终端设备进行数据传输。
可选地，第三载波组合中一个或多个载波组合后的带宽小于预设带宽阈值。可以理解的是，第三载波组合可以是带宽较小的载波组合，网络设备未通过指示信息指示载波组合的情况下，网络设备和终端设备可以使用该第三载波组合中的一个或多个载波进行数据传输，以节省终端设备的功耗。
可选地，第三载波组合可以是网络设备配置的。其中，第三载波组合可以是网络设备通过高层信令、或者通过DCI配置，本申请实施例对此不做限制。
需要说明的是，第三载波组合可以是上述实施例中网络设备预配置的多个载波组合中的任意一个载波组合，也可以是网络设备单独配置的载波组合，本申请实施例对此不做限制。
本申请实施例中，第二载波组合是指终端设备在步骤210之前使用的载波组合。
可选地，第二载波组合可以是特定载波组合(上述第三载波组合)。
可选地，第二载波组合还可以是在步骤210之前，终端设备根据网络设备发送的第三指示信息确定并使用的载波组合。这里，第三指示信息可以用于指示第二载波组合。也就是说，第二载波组合可以是在第一指示信息之前，网络设备通过第三指示信息调度的载波组合。
本申请实施例中，第一指示信息指示的第一载波组合，可以仅在第一时间段内被调度使用，而在第一时间段结束之后，网络设备和终端设备可以切换回原来使用的载波(第二载波组合)，或者特定载波组合(第三载波组合)进行数据传输。
示例性的，终端设备可以在接收到第一指示信息后，启动定时器，该定时器的计时时长可以为第一时间段的时间长度。在该定时器未到期的情况下，终端设备可以通过第一指示信息指示的第一载波组合与网络设备进行数据传输。若该定时器期满，终端设备和网络设备可以将被调度的载波组合从第一载波组合切换为第二载波组合，或，第三载波组合。
需要说明的是，在第二载波组合不是特定载波组合，而是通过第三指示信息确定的载波组合的情况下，终端设备在第一时间段的结束时刻之后，具体切换到第三指示信息调度的第二载波组合，还是特定载波组合，可以是终端设备与网络设备预先约定的，也可以是通过第二载波组合对应的第二时间段来确定。这里，第二时间段是指网络设备调度第二载波组合的时间段。
示例性的，第一时间段可以通过第一定时器实现，第二时间段可以通过第二定时器实现。终端设备接收第三指示信息后，启动第二定时器，在第二定时器运行期间使用第三指示信息指示的第二载波组合进行数据传输。当终端设备在第二定时器运行期间接收到第一指示信息，则启动第一定时器，并在第一定时器运行期间使用第一指示信息指示的第一载波组合记性数据传输。当第一定时器期满时，若第二定时器还未到期，则终端设备可以切换至第三指示信息指示的第二载波组合进行数据传输。当第一定时器期满时，若第二定时器已到期，则终端设备可以切换至特定载波组合进行数据传输。
由此可见，本申请实施例提供的数据传输方法中，网络设备通过第一指示信息指示的第一载波组合，可以仅在第一时间段内使用。并在约定的第一时间段结束后，网络设备和终端设备均切换至原来或特定载波组合进行数据传输，如此，可以降低两个载波组合切换的过程中的信令开销，提高载波的切换效率。
基于上述实施例，在一种可能的实现方式中，第一指示信息可以通过高层信令承载。
应理解，第一指示信息可以为高层信令中的一个字段。也就是说，网络设备通过高层信令(例如RRC连接建立消息、RRC重配置消息、或专用信令等)为终端设备指示所调度的第一载波组合。
在该场景下，第一指示信息还用于去激活第二载波组合，并激活第一载波组合。
也就是说，终端设备接收到携带有第一指示信息的高层信令后，可以基于该高层信令去激活终端设备正在使用的第二载波组合，而激活第一指示信息所配置的第一载波组合，并通过第一载波组合中的一个或多个载波与网络设备进行数据传输。
示例性的，网络设备可以通过高层信令配置并激活的载波组合为{载波1，载波3}，则后续调度中，并利用第一DCI调度载波1和载波3上的传输资源。这样，终端设备可以通过在载波1和载波3对应的传输资源上与网络设备进行数据传输。若网络设备需要 将载波组合变更为{载波3，载波5}时，网络设备可以向终端设备发送高层信令，通过该高层信令去激活当前的载波组合{载波1，载波3}，并激活新的载波组合{载波3，载波5}。
可以理解的是，网络设备可以根据实际的数据传输需求，或者终端设备的节能需求，通过高层信令激活载波组合，这样，提高系统效率并节省终端设备的能耗。
基于前述实施例，在另一种可能的实现方式中，第一指示信息可以通过上述实施例中的第一DCI承载。
可以理解的是，网络设备不仅可以通过第一DCI指示第一载波组合，还可以为终端设备调度第一载波组合中的一个或多个载波上用于数据传输的传输资源。
需要说明的是，NR系统中，网络设备可以为终端设备配置不同的DCI格式，以适用不同的通信场景及调度需求。其中，不同的DCI格式可以通过不同的DCI大小或者DCI中格式指示域区分。另外，为了更好的利用有限的频谱资源，4G系统和5G系统之间可以共享频谱资源。由于4G系统中小区参考信号(Cell Reference Signal，CRS)是必须传输的，并且在5G信号传输时，需要对信号对应的资源位置进行速率匹配等操作，避免4G和5G信号之间的干扰，可以使用一个DCI调度多个载波进行数据传输，在一定程度上，减少下行控制信道的负载。
可选地，当第一载波组合中包括多个载波时，上述第一DCI可以是调度多个载波的DCI格式，也就是说，该第一DCI可以同时调度多个载波。
可选地，载波对应的传输资源可以包括时域资源、频域资源、空域资源中的至少一项，本申请实施例对此不做限制。
可选地，第一DCI可以通过频域指示域指示载波的频域资源，通过时域指示域来指示载波的时域资源。示例性的，第一DCI的频域指示域可以使用比特位图(bitmap)来指示第一载波组合中一个或多个载波的频域资源。其中，频域指示域中一个比特位可以指示第一载波组合中一个或多个载波组成的带宽上多个资源块(Resource Block，RB)。例如，第一DCI的频域指示域中1个比特位指示4个RB。
实际应用中，通过第一DCI承载第一指示信息(也可以理解为通过第一DCI切换载波组合)时，第一DCI实际上调度的第一载波组合中每个载波的传输资源，还可以结合载波组合切换前后的载波参数确定。
可选地，在第一指示信息通过第一DCI承载的场景中，若第一载波组合与第二载波组合不同，则第一载波组合中至少一个载波对应的传输资源可以基于第一载波组合对应的第一参数和第二载波组合对应的第二参数确定。
应理解，在本申请实施例中，在接收第一DCI之前，网络设备调度的是第二载波组合中至少一个载波上的资源。因此，在第一载波组合和第二载波组合不同的情况下，第一DCI的频域指示域，和/或，时域指示域的指示方式会发生改变。具体地，终端设备可以按照与网络设备约定好的规则来确定第一DCI中频域指示域和/或时域指示域具体的指示内容。
可选地，约定好的规则可以是：通过第二载波组合对应的第二参数和第一载波组合对应的第一参数来确定第一DCI实际调度的第一载波组合中至少一个载波的传输资源。
可选地，第一参数可以包括以下中的至少一项：
第一载波组合中至少一个载波的带宽参数、第一载波组合中至少一个载波对应的带宽位置。
对应的，第二参数可以包括以下中的至少一项：第二载波组合中至少一个载波的带宽参数、第一载波组合中至少一个载波对应的带宽位置。
示例性的，第一DCI的频域指示域使用bitmap来指示频域资源的分配时，当载波 组合切换前后的两个载波组合的带宽不同时，频域指示域中每个比特位指示的RB个数就不同。这里，终端设备可以根据第二载波组合的带宽参数和第一载波组合的带宽参数确定第一载波组合中每个载波对应的频域资源。假设第二载波组合的带宽为100个RB，而第一载波组合的带宽为200个RB。网络设备通过DCI 1调度第二载波组合时，该DCI1中频域指示域为25个比特(bit)，其中，每个bit指示4个RB。网络设备通过DCI 2指示将载波组合切换至第一载波组合时，DCI 2中的频域指示域的比特数目与调度第二载波组合的频域指示域比特数相同，均为25比特，此时，每个bit对应8个RB。也就是说，第一载波组合和第二载波组合不同时，调度第一载波组合的第一DCI中频域指示域与RB的对应关系是需要通过调度第二载波组合的DCI来确定。
本申请实施例中，终端设备可以根据预定义规则，利用第二载波组合对应的第二参数和第一载波组合对应的第一参数来确定第一DCI实际调度的第一载波组合中至少一个载波对应的传输资源。也就是说，通过制定上述预定义规则，可以使得终端设备和网络设备在载波组合切换过程中，对第一DCI中调度信息的解析有相同的理解，从而使终端设备和网络设备的数据能够正常传输。
可选地，在第一指示信息通过第一DCI承载的场景中，若第一载波组合与第二载波组合相同，则第一载波组合中可以基于第一载波组合对应的第一参数确定。
应理解，在第一载波组合和第二载波组合相同的情况下。具体地，终端设备可以直接根据第一载波组合中一个或多个载波对应的带宽参数和/或带宽位置，来确定第一载波组合中至少一个载波每个载波对应传输资源。如此，可以使得终端设备和网络设备在载波组合切换过程中，对第一DCI中调度信息的解析有相同的理解，从而使终端设备和网络设备的数据能够正常传输。
示例性的，若第二载波组合和第一载波组合相同，在非第一个调度第一载波组合的DCI中，频域指示域的长度可以根据第一载波组合的带宽及指示粒度确定，可以是25比特，也可以是其他比特数目，本申请实施例对此不作限制。
综上所述，本申请实施例中，网络设备可以根据终端设备实时的数据传输需求，通过第一DCI来快速切换载波组合并指示载波组合中每个载波对应的传输资源，而不必通过高层信令进行载波组合的指示又通过第一DCI指示载波组合中每个载波对应的传输资源，减少了处理时间，同时提高了载波组合的切换效率。
需要说明的是，在通过高层信令配置载波组合的场景中，网络设备也可以根据实际调度需求，通过DCI切换高层信令配置的载波组合。另外，在通过DCI配置载波组合的场景中，网络设备也可以向终端设备发送高层信令，通过高层信令切换载波组合。本申请实施例对此不做限制。
