第一信息可以用于指示两个载波，也可以用于指示一个载波中的两个频域资源，例如，用于指示一个载波中的两个物理资源块(physical resource block，PRB)集合或两个子信道集合，第一终端设备可以通过该两个PRB集合或该两个子信道集合向第二终端设备或者网络设备发送对应相同传输块的至少两个数据。
第一终端设备从网络设备接收第一信息之后，第一终端设备可以在第一信息指示的至少两个载波上向第二终端设备或者网络设备发送至少两个数据，该至少两个数据对应相同的传输块，从而可以提高数据传输的可靠性，该至少两个数据可以同时发送，从而避免了在不同的时间单元多次传输该至少两个数据导致的时延增大。第一终端设备通过至少两个载波发送至少两个数据的方式可以是以载波聚合的方式发送该至少两个数据，也可以是以其它方式发送该至少两个数据。
在本申请中，第一终端设备可以同时发送对应相同传输块的至少两个数据，也可以不同时发送该至少两个数据，当该至少两个数据在不同的时间单元(例如，时域符号或者时隙或者子帧)发送时，第一终端设备可以提高发射功率，从而有利于提高数据传输的可靠性。
在本申请中，网络设备可以通过第一信息指示对应相同传输块的多个数据的传输时间间隔，网络设备也可以在发送第一信息前通过配置信息配置上述传输时间间隔，第一终端设备也可以预设信息确定上述传输时间间隔。应理解，上述多个数据中相邻的两个数据的传输时间间隔可以相同，也可以不同。
此外，网络设备也可以通过第一信息指示的至少两个载波向第一终端设备发送对应相同传输块的至少两个数据，下面均以第一终端设备发送对应相同传输块的至少两个数据对本申请进行说明，但本申请不限于此。
可选地，第一信息包括至少两个第一标识信息，该至少两个第一标识信息用于指示至少两个载波。
第一标识信息例如可以是CIF，网络设备可以向第一终端设备发送多个第一信息，每个第一信息除了包括该第一信息使用的载波的CIF之外还可以包括其它载波的CIF，从而第一终端设备可以根据CIF确定至少两个载波，方案简单易实施。
图3示出了本申请提供的一种指示两个载波的方法的示意图。
网络设备向第一终端设备发送了两个下行控制信息(downlink control information，DCI)，分别为DCI1和DCI2，如图3所示，DCI1包括两个CIF，其中一个CIF的值为1，指示第一终端设备在CIF为1的载波上发送数据，DCI1还包括CIF为1的载波的调度信息，另一个CIF的值为2，指示第一终端设备在CIF为2的载波上发送数据，该两个CIF共同指示第一终端设备发送对应相同传输块的两个数据。DCI2也包括两个CIF，该两个CIF的值分别为1和2，与DCI1不同的是，DCI2包括的载波调度信息是CIF为2的载波的调度信息。
第一终端设备接收到DCI1和DCI2后可以根据DCI1和DCI2确定在CIF为1和2的两个载波上发送对应相同传输块的两个数据，例如，第一终端设备可以根据DCI1中的两个CIF与DCI2中的两个CIF相同确定在CIF为1和2的两个载波上发送对应相同传输块的数据。网络设备通过两个DCI而非一个DCI调度该两个载波的有益效果在于：在现有的DCI格式的基础上仅需增加一个CIF即可，无需在DCI中增加载波调度信息，方案简单易实施。
应理解，在图3所示的信息中，DCI1或DCI2相当于S201中的第一信息，DCI1或DCI2中的两个CIF相当于至少两个第一标识信息；也可以将DCI1和DIC2看作第一信息，将DCI1和DIC2中的四个CIF看作至少两个第一标识信息。
当网络设备确定某个载波不与其它载波传输对应相同传输块的数据时，网络设备可以将DCI包括的多个CIF中的一个CIF设置为特殊值，例如，DCI1携带的载波调度信息是CIF为1的载波的调度信息，则网络设备可以将DCI1中的其它CIF的值设置为0。或者，网络设备还可以将两个CIF设置为相同的值，例如，网络设备可以将DCI1中的两个CIF的值均设置为1。
当网络设备指示第一终端设备在三个或三个以上的载波上传输对应相同传输块的数 据时，可以按照图3所示的方法，在一个DCI中通过三个或三个以上的CIF指示至少三个载波，也可以按照图4所示的方法指示至少三个载波。
图4示出了本申请提供的一种指示三个载波的方法的示意图。
如图4所示，网络设备向第一终端设备发送三个DCI，分别为DCI1、DCI2和DCI3，每个DCI包括两个CIF，DCI1还包括CIF为1的载波的调度信息，DCI2还包括CIF为2的载波的调度信息，DCI3还包括CIF为3的载波的调度信息，第一终端设备接收到该三个DCI后，根据DCI1中的第一个CIF(CIF＝1)和第二个CIF(CIF＝2)以及DCI2中的第一个CIF(CIF＝2)确定CIF为1和2的两个载波传输对应相同传输块的数据，根据DCI2的第一个CIF(CIF＝2)和第二个CIF(CIF＝3)以及DCI2中的第一个CIF(CIF＝3)确定CIF为2和3的两个载波传输对应相同传输块的数据，根据DCI3的第一个CIF(CIF＝3)和第二个CIF(CIF＝1)以及DCI1中的第一个CIF(CIF＝1)确定CIF为3和1的两个载波传输对应相同传输块的数据，从而确定在CIF为1、2和3的三个载波上发送对应相同传输块的数据。相比于在一个DCI中通过三个CIF指示三个载波的方法，图4所示的方法减少了信息开销。
作为一个可选的示例，当第一终端设备分别确定了CIF为1和2的两个载波传输对应相同传输块的数据，以及CIF为2和3的两个载波传输对应相同传输块的数据之后，即可确定在CIF为1、2和3的三个载波上发送对应相同传输块的数据，因此，第一终端设备无需再根据DCI3和DCI1确定CIF为3和1的两个载波传输对应相同传输块的数据，也就是说，DCI3的第二个CIF可以设置为一个特殊值用于终结载波的对应关系，例如，可以将DCI3的第二个CIF设置为0，或者，将DCI3的两个CIF设置为3。
应理解，图4所示的信息中，DCI1、DCI2和DCI3中的任意一个DCI相当于S201中的第一信息，该三个DCI中的任意一个DCI中的两个CIF相当于至少两个第一标识信息；也可以将DCI1、DCI2和DCI3看作第一信息，将该三个DCI中的包括的全部CIF看作至少两个第一标识信息。
图4所示的方法中，网络设备可以按照顺序指示两个载波传输的数据的时间间隔，例如，网络设备可以通过DCI1指示CIF为1的载波上传输的数据与CIF为2的载波上传输的数据的第一时间间隔，网络设备也可以通过DCI2指示CIF为2的载波上传输的数据与CIF为3的载波上传输的数据的第二时间间隔，第一时间间隔与第二时间间隔可以相同，也可以不同，当第一时间间隔与第二时间间隔相同时，网络设备可以通过一个DCI(DCI1或DCI2)指示两个载波上传输的数据的时间间隔。需要说明的是，上述数据均指对应相同传输块的数据，上述方法也适用于图3、图5和图6所示的方法。
可选地，第一信息包括至少两个指示信息，该至少两个指示信息中任意一个指示信息包括一个第一标识信息和一个第二标识信息，一个第一标识信息用于指示至少两个载波中的一个，该至少两个指示信息中的第二标识信息相同，该至少两个指示信息中的第二标识信息用于指示至少两个载波传输对应相同传输块的至少两个数据。
本实施例中，具有相同的第二标识信息的载波用于传输对应相同传输块的数据，因此，网络设备仅需增加一个标识信息字段即可同时调度第一终端设备传输多个传输块对应的数据，方案简单易实施。
图5示出了本申请提供的另一种指示两个载波的方法的示意图。
网络设备向第一终端设备发送三个DCI，分别为DCI1、DCI2和DCI3，每个DCI包括一个CIF(即，第一标识信息)和一个S(即，第二标识信息)，该一个CIF用于指示该DCI中携带的载波调度信息所对应的载波，S值相同的DCI所指示的载波用于传输对应相同传输块的数据。
如图5所示，该三个DCI中仅有DCI1的S的值与其它DCI的S的值不同，因此，第一终端设备接收到该三个DCI后确定CIF为1的载波不与其它载波传输对应相同传输块的数据，CIF为2和3的载波用于传输对应相同传输块的至少两个数据。
网络设备还可以设置S的大小为2比特，这样，S最多可以指示4种状态，每种状态对应一组用于传输相同传输块的载波，从而，网络设备可以同时调度第一终端设备传输多个传输块对应的数据。
图6示出了本申请提供的一种指示多组载波的方法的示意图。
网络设备向第一终端设备发送五个DCI，分别为DCI1、DCI2、DCI3、DCI4和DCI5，每个DCI包括一个CIF和一个S，其中，可以将DCI1的S的值设置为特殊值，该特殊值例如为0，该特殊值表示DCI1指示的载波所传输的数据与其它DCI指示的载波所传输的数据不同。图6仅示出了一个S的值为特殊值的DCI(即DCI1)，网络设备还可以向第一终端设备发送多个S的值为特殊值的DCI，该多个S的值为特殊值的DCI所指示的载波传输的数据各不相同。
DCI2和DIC3的S的值相同，DCI4和DCI5的S的值相同，第一终端设备接收到该五个DCI后，确定CIF为1的载波不与其它载波传输对应相同传输块的数据，CIF为2和3的载波用于传输对应第一传输块的至少两个数据，CIF为4和5的载波用于传输对应第二传输块的至少两个数据。
可选地，第一信息包括一个第一标识信息，该一个第一标识信息用于指示至少两个载波。
通信***可以预先配置至少两个载波的标识信息为第一标识信息，该两个载波的时频资源池的关系也可以预先配置，这样，网络设备仅需发送一个第一标识信息即可调度第一终端设备通过至少两个载波传输至少两个数据，从而可以减小信令开销。
可选地，网络设备向第一终端设备发送第一信息之前，方法200还包括：
S203，网络设备向第一终端设备发送第一配置信息和第二配置信息，第一配置信息用于配置至少两个载波的标识信息为第一标识信息，第二配置信息用于配置至少两个载波对应的时频资源池。
S203中，第一配置信息和第二配置信息可以同时发送，也可以不同时发送，本申请对此不作限定。网络设备通过配置信息配置至少两个载波的标识信息以及该至少两个载波的时频资源池，从而可以灵活调度第一终端设备通过至少两个载波传输至少两个数据。
图7是本申请提供的再一种指示两个载波的方法的示意图。
网络设备通过第二配置信息配置载波1和载波2使用完全相同的时频资源池(以下，简称为“资源池”)，例如，载波1上配置有资源池1，以及载波2配置有资源池1’，资源池1和资源池1’在时域上都包括子帧1、3、5和7，两个资源池在频域上都包括序号为1～20的PRB，该两个资源池的频域还可以包括相同的子信道(subchannel)个数，每个子信道包括的PRB的个数也可以相同。
网络设备通过第一配置信息为载波1和载波2配置一个公共的CIF值，例如，CIF值为1。
网络设备向第一终端设备发送一个DCI，该一个DCI包括一个CIF(即，第一信息包括一个第一标识信息)，该CIF的值为1。
第一终端设备接收到该DCI后，确定在CIF为1的两个载波上发送对应相同传输块的至少两个数据。第一终端设备可以根据该DCI携带的载波调度信息通过载波1和载波2上发送对应相同传输块的至少两个数据。
上述实施例仅是举例说明，本申请不限于此，例如，资源池1和资源池1’也可以是不同配置的资源池，网络设备分别配置两个资源池，或者，网络设备配置其中一个资源池，并将两个资源池的对应关系(例如，频域偏移量或时域偏移量)发送给第一终端设备，从而第一终端设备可以根据第一信息确定至少两个载波的资源配置。
可选地，第一配置信息承载于广播消息或RRC专用消息(例如，RRC连接重配置消息)中；第二配置信息承载于广播消息或RRC专用消息中。
网络设备可以通过广播消息配置至少两个载波，当第一终端设备通过该至少两个载波向第二终端设备发送数据时，无需再向第二终端设备指示该至少两个载波传输对应相同传输块的数据，从而减小了信令开销。
可选地，第一信息包括一个第一标识信息，该一个第一标识信息用于指示至少两个载波的一个。
通信***可以预先配置至少两个载波的标识信息的关联关系，该关联关系用于指示至少两个载波传输对应相同传输块的至少两个数据，网络设备仅需发送一个第一标识信息即可调度第一终端设备通过至少两个载波传输至少两个数据，从而减少了信令开销。
可选地，网络设备向第一终端设备发送第一信息之前，方法200还包括：
S204，网络设备向第一终端设备发送第二配置信息和第三配置信息，该第二配置信息用于配置至少两个载波对应的时频资源池，该第三配置信息用于配置关联关系，该关联关系用于指示至少两个载波传输对应相同传输块的至少两个数据。
任意能够直接或间接指示至少两个载波传输对应相同传输块的至少两个数据的关联关系都落入本申请保护的范围，例如，网络设备可以通过第三配置信息配置至少两个载波的标识信息具有上述关联关系，从而可以灵活调度第一终端设备通过至少两个载波传输至少两个数据。
图8是本申请提供的再一种指示两个载波的方法的示意图。
网络设备通过第二配置信息配置载波1和载波2使用完全相同的时频资源池(以下，简称为“资源池”)，载波1对应资源池1，载波2对应资源池1’。
网络设备通过第三配置信息配置载波1(CIF＝1)和载波2(CIF＝2)的关联关系，该关联关系用于指示载波1和载波2传输对应相同传输块的至少两个数据。
网络设备向第一终端设备发送一个DCI，该一个DCI包括一个CIF(即，第一信息包括一个第一标识信息)，该一个CIF的值为1或2中任意一个。
第一终端设备接收到该DCI后，根据该DCI和上述关联关系确定载波1和载波2传输对应相同传输块的至少两个数据。
上述实施例仅是举例说明，本申请不限于此，例如，资源池1和资源池1’也可以是不 同配置的资源池，网络设备分别配置两个资源池，或者，网络设备配置其中一个资源池，并将两个资源池的对应关系(例如，频域平移量或时域平移量)发送给第一终端设备，从而第一终端设备可以根据第一信息确定至少两个载波的资源配置。
可选地，第二配置信息承载于广播消息或RRC专用消息中；第三配置信息承载于广播消息或RRC专用消息中。
网络设备可以通过广播消息配置至少两个载波，当第一终端设备通过该至少两个载波向第二终端设备发送数据时，无需再向第二终端设备指示该至少两个载波传输对应相同传输块的数据，从而减小了信令开销。
可选地，在本申请中，第一终端设备发送的对应相同传输块的至少两个数据可以是相同的冗余版本，也可以是不同的冗余版本。
例如，第一终端设备可以在各个载波上均传输一个相同且固定的冗余版本，即，各个载波传输的数据的冗余版本相同且该冗余版本不随时间变化，则网络设备无需再向第一终端设备指示冗余版本，第一终端设备在向第二终端设备发送时也无需指示冗余版本，第二终端设备或网络设备接收到数据时按照默认的冗余版本进行解码。
又例如，第一终端设备在各个载波上均传输一个相同且可变的冗余版本，即，各个载波传输的数据的冗余版本相同且该冗余版本可随时间变化，在该情况下，网络设备需要向第一终端设备指示第一终端设备发送数据使用的冗余版本，第一终端设备也需要向第二终端设备指示第一终端设备发送数据使用的冗余版本，以便于第二终端设备解码数据。
再例如，第一终端设备可以在各个载波上传输不同的冗余版本，网络设备可以向第一终端设备指示各个载波对应的冗余版本，第一终端设备可以向第二终端设备指示各个载波对应的冗余版本；或者，网络设备不向第一终端设备指示各个载波对应的冗余版本，第一终端设备不向第二终端设备指示各个载波对应的冗余版本，第一终端设备按照各个载波与冗余版本存在对应关系发送数据，第二终端设备或网络设备也按照各个载波与冗余版本的对应关系对接收到的数据进行解码。
上述各个载波与冗余版本的对应关系可以是冗余版本号与CIF值的对应关系，例如，冗余版本号按照0、1、2、3的顺序排列，载波的CIF值按照1、2、3的顺序排列，则载波1对应冗余版本0，载波2对应冗余版本1，载波3对应冗余版本2。
上述各个载波与冗余版本的对应关系还可以是冗余版本号顺序与载波配置顺序的对应关系，还可以是DCI指示的载波的顺序与冗余版本号顺序的对应关系，还可以是其它可以用于确定载波对应的冗余版本号的对应关系。

若网络设备未向第二终端设备指示S901中所述的至少两个载波，则第一终端设备需要向第二终端设备指示该至少两个载波以及指示该至少两个载波用于传输对应相同传输块的至少两个数据。
第一终端设备可以通过第二信息指示该至少两个载波以及指示该至少两个载波用于传输对应相同传输块的至少两个数据，第二信息可以是一个信息，也可以是多个信息，第一终端设备可以发送一个第二信息，也可以发送多个第二信息。第二信息可以在发送该至少两个数据之前发送，第二信息也可以与该至少两个数据在同一个时间单元内发送。

与第一信息不同的是，由于第一终端设备和第二终端设备可以根据预设信息确定第一载波为S907所述的至少两个载波中的一个，因此，第二信息可以只包括一个第一标识信息。
上述实施例仅是举例说明，本申请提供的发送数据的方法不限于此，例如，第二信息所指示的至少两个载波也可以不包括第一载波。
下面，将从第二终端设备的角度描述本申请提供的接收数据的方法。
图10示出了本申请提供的一种接收数据的方法的示意图。该方法1000包括：
S1001，第二终端设备通过第一载波从第一终端设备接收第二信息，该第二信息用于指示第二载波，第一载波为至少两个载波中的一个，第二载波为该至少两个载波中除第一载波之外的至少一个载波，且该第二信息用于指示至少两个载波传输对应相同传输块的至少两个数据。
S1002，第二终端设备通过至少两个载波从第一终端设备接收至少两个数据。

又例如，第二终端设备配置有三个载波，分别为载波1、载波2和载波3，第一终端设备在载波1上向第二终端设备发送一个第二信息，该第二信息用于指示载波2；第一终端设备在载波2上向第二终端设备发送另一个第二信息，该第二信息用于指示载波1。则第二终端设备接收到该两个第二信息后即可根据该两个第二信息确定载波1和载波2传输对应相同传输块的至少两个数据。
第二终端设备也可以不根据第二信息确定至少两个载波，例如，第二终端设备没有接收到第二信息时，可以确定载波1、载波2和载波3传输的数据对应相同的传输块。
第二终端设备接收到S1002所述的至少两个数据后，作为一个可选的示例，第二终端设备可以对该至少两个数据进行合并解码，以提高解码成功率。作为另一个可选的示例，第二终端设备成功解码了至少两个数据中的一个数据后可以不再进行合并解码，上述成功解码包括数据校验通过，例如，当数据包括的传输块的循环冗余校验(cyclic redundancy check，CRC)和编码块的CRC均校验通过时，该数据解码成功。
根据本实施例提供的接收数据的方法，第二终端设备先从第一终端设备接收第二信息，该第二信息指示至少两个载波传输对应相同传输块的至少两个数据，随后在该至少两个载波上从第一终端设备接收该至少两个数据，从而可以提高数据传输的可靠性，该至少两个数据可以同时发送，从而避免了在不同的时间单元多次传输该至少两个数据导致的时延增大。
