传输数据的方法、终端设备和网络设备 技术领域
本申请实施例涉及无线通信领域，并且更具体地，涉及一种传输数据的方法、终端设备和网络设备。

具体实施方式
下面将结合附图，对本申请实施例中的技术方案进行描述。
应理解，本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile Communication，简称“GSM”)系统、码分多址(Code Division MultipleAccess，简称“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access，简称“WCDMA”)系统、长期演进(Long Term Evolution，简称“LTE”)系统、LTE频分双工(Frequency Division Duplex，简称“FDD”)系统、LTE时分双工(Time Division Duplex，简称“TDD”)、通用移动通信系统(Universal Mobile Telecommunication System，简称“UMTS”)、以及未来的5G通信系统等。
本申请结合终端设备描述了各个实施例。终端设备也可以指用户设备(User Equipment，简称“UE”)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，简称“SIP”)电话、无线本地环路(Wireless Local Loop，简称“WLL”)站、个人数字处理(Personal Digital Assistant，简称“PDA”)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的陆上公用移动通信网(Public Land Mobile Network，简称“PLMN”)网络中的终端设备等。
本申请结合网络设备描述了各个实施例。网络设备可以是用于与终端设备进行通信的设备，例如，可以是GSM系统或CDMA中的基站(Base  Transceiver Station，简称“BTS”)，也可以是WCDMA系统中的基站(NodeB，简称“NB”)，还可以是LTE系统中的演进型基站(Evolutional Node B，简称“eNB”或“eNodeB”)，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络侧设备或未来演进的PLMN网络中的网络侧设备等。
图1是本申请实施例的一个应用场景的示意图。图1中的通信系统可以包括网络设备10和终端设备20。网络设备10用于为终端设备20提供通信服务并接入核心网，终端设备20可以通过搜索网络设备10发送的同步信号、广播信号等而接入网络，从而进行与网络的通信。图1中所示出的箭头可以表示通过终端设备20与网络设备10之间的蜂窝链路进行的上/下行传输。
本申请实施例中的网络可以是指公共陆地移动网络(Public Land Mobile Network，简称“PLMN”)或者设备对设备(Device to Device，简称“D2D”)网络或者机器对机器/人(Machine to Machine/Man，简称“M2M”)网络或者其他网络，图1只是举例的简化示意图，网络中还可以包括其他终端设备，图1中未予以画出。
目前长期演进(Long Term Evolution，简称“LTE”)系统的整个系统带宽中，物理下行控制信道(Physical Downlink Contol Channel，简称“PDCCH”)占用一个子帧中的前面几个符号进行传输，PDCCH所占的符号数是由同一子帧中的物理控制格式指示信道(Physical Control Format Indicator Channel，简称“PCFICH”)进行指示的，因此，物理下行共享信道(Physical Downlink Shared CHannel，简称“PDSCH”)在一个子帧内占用哪些符号，也就可以根据同一子帧中PCFICH所指示的PDCCH占用的符号的信息推导得出，而不需要额外向终端指示。
但在5G新无线(New Radio，简称“NR”)系统中，一个时域资源单元，或者称时域调度单位例如时隙(slot)、微时隙(mini-slot)中，前面几个符号也可能是有PDCCH存在的，但具体有几个符号用于传输PDCCH，在每个资源块(Physical Resource Block，简称“PRB”)中是可以不同的。从基站在某个PRB中向终端传输PDSCH时，该PRB内用于传输PDSCH的起始符号可以通过下行控制信息(Downlink Control Information，简称“DCI”)进行指示。另外，5G系统中将支持“双向时隙”，即一个时隙的前半部分可以用于下行传输，而后半部分可以用于上行传输，因此一个时隙的最后几个 符号可能并不是用来传输PDSCH而是用来传输物理上行链路控制信道(Physical Uplink Control Channel，简称“PUCCH”)等上行信道的，而该PUCCH在该时隙中所占用的符号数也可以通过DCI进行指示。因此，5G系统中一个时隙中哪些符号用于传输PDSCH也是可以通过DCI来获知的。
而对于物理上行共享信道(Physical Uplink Shared Channel，简称“PUSCH”)，在LTE系统中，PUSCH在一个子帧内占用哪几个符号，是根据帧结构静态确定的，因此在基站为终端分配的用于传输PUSCH的资源在子帧中的资源位置就是完全确定的，不需要额外指示给终端。但在5G系统中，一个时域资源单元中当基站为终端调度了某个PRB后，该PRB内的PUSCH可能占满整个时域资源单元，也可能只占用该时域资源单元中的几个符号而其他符号由PUCCH、PDCCH等其他信道占用。因而，5G系统中是通过DCI来指示用于传输PUCCH、PDCCH等的资源位置的。
另外，在5G系统中支持跨时隙调度，即通过第n个时隙中传输的DCI来调度第n+i个时隙的数据信道的传输(n、i为正整数)。但是，如果在第n个时隙，基站尚未确定第n+i个时隙中用于传输控制信道或数据信道的时域资源位置，那么基站就无法实现提前对第n+i个时隙的数据信道的调度。
例如图2所示的PDSCH的资源配置方式，第n+i个时隙的开始部分的符号被下行控制信道PDCCH占用，如果基站确定用于传输PDCCH的时域资源的长度的时刻T2，晚于第N个时隙中的DCI(携带PDSCH的下行资源配置(Download Assignment，简称“DLAssignment”)的信息)发送的时刻T1，则终端设备无法根据接收到的DLAssignment预先获知用于传输PDCCH的时域资源的位置，也就无法预先获知用于传输PDSCH的准确的时域资源位置。
又例如图3所示的PDSCH的资源配置方式，第n+i个时隙的起始部分的符号被下行控制信道PDCCH占用，且第n+i个时隙的末尾部分的符号被上行控制信道PUCCH占用，如果基站确定是否在该时隙末尾传输PUCCH的时刻或基站确定该时隙中用于传输该PUCCH的时域资源的长度的时刻T2，晚于第n个时隙中的DCI(携带PDSCH的DL Assignment的信息)发送的时刻T1，则终端设备无法根据接收到的DL Assignment预先获知该时隙中是否存在上行信道以及用于传输该上行信道的时域资源的位置，也就无法预先获知用于传输PDSCH的准确的时域资源位置。
又例如图4所示的PUSCH的资源配置方式，第n+i个时隙的一部分符号被上行控制信道PUCCH占用，如果基站确定用于传输PUCCH的时域资源的长度的时刻T2，晚于第N个时隙中的DCI(携带PUSCH的上行资源配置(Uplink Grant，简称“UL Grant”)的信息)发送的时刻T1，则终端设备无法根据接收到的DL Assignment预先获知用于传输PUCCH的时域资源的位置，也就无法预先获知用于传输PUSCH的准确的时域资源位置。
又例如图5所示的PUSCH的资源配置方式，第n+i个时隙的起始部分的符号被上行控制信道PDCCH占用，且该时隙中的一部分符号被上行信道例如PUCCH占用，如果基站确定是否在该时隙开头传输下行信道的时刻或基站确定该时隙中用于传输该下行信道的时域资源的长度的时刻T2，晚于第n个时隙中的DCI(携带PUSCH的UL Grant的信息)发送的时刻T1，则终端设备无法根据接收到的UL Grant预先获知该时隙中是否存在上行信道以及用于传输该上行信道的时域资源的位置，也就无法预先获知用于传输PUSCH的准确的时域资源位置。
图6是根据本申请实施例的传输数据的方法600的示意性流程图。图6中的传输数据的方法可以由终端设备例如图1中所示的终端设备20执行。如图6所示，该传输数据的具体流程包括：
在610中，终端设备在第一时刻接收网络设备发送的第一资源指示信息。
其中，该第一时刻位于第n个时域资源单元，该第一资源指示信息指示第n+i个时域资源单元中用于传输终端设备的目标信道的频域资源，该目标信道包括终端设备的数据信道或控制信道，n和i为正整数。
具体来说，终端设备在第n个时域资源单元(或称时域调度单位)中的第一时刻上，接收网络设备发送的第一资源指示信息，而该第一资源指示信息指示的是第n+i个时域资源单元中用于传输所述终端设备的目标信道的频域资源。也就是说，第n个时域资源单元上发送的第一资源指示信息，是用于调度第n+i个时域资源单元上目标信道传输的频域资源的。这种跨时隙调度可以使终端设备有充分的时间为之后的数据传输做准备。
应理解，在本申请实施例中，第n个时域资源单元和第n+i个时域资源单元是为了表示两个时域资源单元之间的时域位置关系，第n个时域资源单元可以理解为当前的时域资源单元，第n+i个时域资源单元可以该是当前时域资源单元之后的第i个时域资源单元。也就是说，第n个时域资源单元可 以由第一时域资源单元代替，第n+i个时域资源单元可以由第二时域资源单元代替，第二时域资源单元是第一时域资源单元之后的任意一个时域资源单元。可选地，如果第二时域资源单元是第一时域资源单元之后第i个时域资源单元，该第一资源指示信息中还可以包括i的值。
可选地，终端设备的数据信道可以包括以下中的任意一种：上行数据信道、下行数据信道和副链路数据信道。
在620中，终端设备在位于所述第一时刻之后的第二时刻，接收所述网络设备发送的第二资源指示信息。
其中，该第二资源指示信息指示第n+i个时域资源单元中用于传输该数据信道的时域资源。
可选地，第n+i个时域资源单元中用于传输该目标信道的该时域资源，是网络设备在所述第一时刻之后确定的。
可选地，该第二资源指示信息为该终端设备的专有信息(UE specific)。
可选地，该第n个时域资源单元包括以下中的任意一种：第n个时隙、第n个迷你时隙和第n个子帧。
在5G系统中，时域资源单元可以是时隙(slot)、迷你时隙(mini-slot，或称微时隙)、或者子帧(subframe)。第n个时域资源单元可以是第n个时隙、第n个迷你时隙和第n个子帧；第n+i个时域资源单元可以是第n+i个时隙、第n+i个迷你时隙和第n+i个子帧
可选地，终端设备用于接收该第一资源指示信息的物理信道，与用于接收该第二资源指示信息的物理信道可以不同。
在跨时隙调度中，在第n个时隙，网络设备有可能尚未确定第n+i个时隙中用于传输控制信道或数据信道的时域资源位置，那么网络设备就无法实现提前对第n+i个时隙的目标信道的调度。因而，网络设备可以首先通过第一资源指示信息指示第n+i个时域资源单元中用于传输该目标信道的频域资源，并在第一时刻之后的第二时刻向终端设备配置第n+i个时域资源单元中用于传输该目标信道的时域资源。在第二时刻网络设备已经确定好第n+i个时域资源单元中用于传输该目标信道的时域资源。
由于终端设备在第一时刻之后的第二时刻，会接收到网络设备发送的第二资源指示信息从而获取第n+i个时域资源单元中用于传输该目标信道的时域资源，那么终端设备就可以根据第一资源指示信息和第二资源指示信息， 确定第n+i个时域资源单元中用于传输目标信道的时频资源。
可选地，该第二资源指示信息指示的所述时域资源包括以下中的至少一种：该第n+i个时域资源单元中用于传输该目标信道的符号的起始位置、用于传输该目标信道的符号的数量、用于传输该目标信道的迷你时隙、和用于传输该目标信道的迷你时隙的数量。
具体来说，终端设备接收的该第二资源指示信息，可以指示用于传输目标信道的时域资源在第n+i个时域资源单元中占用的符号的起始位置和/或占用的符号数量；该第二资源指示信息也可以指示用于传输目标信道的时域资源在第n+i个时域资源单元中占用的迷你时隙的起始位置和/或占用的迷你时隙的数量，这时一个时域资源单元中可以包括若干个迷你时隙；如果一个时域资源单元中可以包括若干个迷你时隙，且每个迷你时隙中又包括若干个符号，那么该第二资源指示信息还可以指示用于传输目标信道的时域资源在第n+i个时域资源单元中占用的迷你时隙的信息，以及在该迷你时隙中占用的符号的信息。这里不做限定。
可选地，该第二资源指示信息还可以包括该时域资源的标识，该第二资源指示信息指示的该时域资源为预设的多个时域资源中与该标识对应的时域资源。
也就是说，第n+i个时域资源单元中用于传输目标信道的时域资源，可以是预设的多种时域资源配置中的一种，具体可以通过与时域资源对应的标识来确定。例如标识1对应的时域资源为时隙中的第2-7个符号，标识2对应的时域资源为时隙中的第3-7个符号等等，如果第二资源指示信息中携带标识1，那么在该时隙中终端设备就会在第2-7个符号上传输目标信道。
可选地，该第一资源指示信息还指示该第n+i个时域资源单元中用于传输该目标信道的时域资源。
如果第一资源指示信息不仅指示了第n+i个时域资源单元中用于传输该目标信道的频域资源，还指示了该第n+i个时域资源单元中用于传输该目标信道的时域资源，那么终端设备可以通过以下两种方式对第一资源指示信息和第二资源指示信息进行联合处理。
方式1
可选地，该方法还包括：终端设备确定第一资源指示信息指示的时域资源，与第二资源指示信息指示的时域资源是否相同；若第一资源指示信息指 示的时域资源，与第二资源指示信息指示的时域资源不同，则终端设备确定使用第二资源指示信息指示的该时域资源传输该目标信道。
该实施例中，第一资源指示信息指示的第n+i个时域资源单元中传输目标信道的时域资源，与第二资源指示信息指示的第n+i个时域资源单元中传输数据的时域资源，如果不相同，或者说发生冲突，那么终端设备会选择第二资源指示信息指示的该时域资源作为在第n+i个时域资源单元中传输目标信道的时域资源。
因为在进行资源调度时，网络设备是可以先通过第一时域资源指示给终端设备一个默认的时域资源位置，该默认的时域资源位置例如可以是统计后获得的终端设备最可能使用的传输目标信道的位置，如果在第一时刻之后终端设备没有接收到第二资源指示信息，那么该终端设备确定在第一资源指示信息指示的时域资源上传输目标信道，如果第一时刻之后网络设备重新确定了第n+i个时域资源单元中传输目标信道的时域资源，那么终端设备会接收到网络设备在第二时刻发送的第二资源指示信息，并且以该第二资源指示信息所指示的时域资源位置为准，确定在第二资源指示信息指示的时域资源上传输目标信道。第二资源指示信息可以认为是第一资源指示信息的补充与修正，终端设备在接收到第二资源指示信息时，应将第二资源指示信息指示的时域资源作为待传输目标信道的时域资源。
方式2
可选地，该方法还包括：终端设备根据第二资源指示信息，在第一资源指示信息指示的时域资源的范围内，确定用于传输该目标信道的该时域资源。
该实施例中，第一资源指示信息指示的第n+i个时域资源单元中传输目标信道的时域资源的范围，大于第二资源指示信息指示的第n+i个时域资源单元中传输数据的时域资源。网络设备可以通过第一资源指示信息先向终端设备指示一个大致的时域资源的范围，并在具体确定了第n+i个时域资源单元中传输目标信道的时域资源后，再通过第二资源指示信息指示第n+i个时域资源单元中传输目标信道的具体的时域资源位置。
以目标信道为数据信道为例，假设时域资源单元为子帧，第一资源指示信息指示的第n+i个子帧中传输数据信道的时域资源为该子帧中的第一个时隙，而第二资源指示信息指示指示的第n+i个子帧中传输数据信道的时域资 源具体为该第一个时隙中的第2-7个符号。
又例如，时域资源单元为时隙，第一资源指示信息指示的第n+i个时隙中传输数据信道的时域资源为该子帧中的第一个迷你时隙，而第二资源指示信息指示指示的第n+i个时隙中传输数据信道的时域资源具体为该第一个迷你时隙中的第1个符号。
可选地，在620中终端设备在位于第一时刻之后的第二时刻，接收所述网络设备发送的第二资源指示信息，包括：终端设备在位于第一时刻之后的第二时刻，在预设的频域资源上，接收网络设备发送的该第二资源指示信息。
即，终端设备用于接收第二资源指示信息的时频资源是预先约定的。例如第二资源指示信息的时频资源位置可以和第一资源指示信息的时频资源位置之间存在固定的位置关系。终端设备接收第一资源指示信息之后，就可以知道在哪个时频资源上接收第二资源指示信息。其中，接收该第二资源指示信息的时域资源即该第二时刻。
进一步地，可选地，第一资源指示信息包括用于接收第二资源指示信息的该第二时刻和该预设的频域资源，在终端设备接收网络设备发送的第二资源指示信息之前，该方法还包括：
终端设备根据该第一资源指示信息，确定用于接收该第二资源指示信息的第二时刻和该预设的频域资源。
即，终端设备用于接收第二资源指示信息的时频资源的信息，是携带在第一资源指示信息中的。终端设备在第一时刻接收第一资源指示信息后，不仅可以从第一资源指示信息中获取第n+i个时域资源单元中用于传输目标信道的频域资源，还可以从第一资源指示信息中获取用于接收第二资源指示信息的时域资源即第二时刻和频域资源，从而终端设备进一步从第二时刻接收的第二资源指示信息中获取第n+i个时域资源单元中用于传输目标信道的时域资源。
可选地，在620之后，该方法还包括630。
在630中，终端设备在第n+i个时域资源单元中的该频域资源和该时域资源上，向网络设备发送该目标信道，或者接收网络设备发送的该目标信道。
终端设备根据第一资源指示信息获取用于传输目标信道的频域资源，并根据第二资源指示信息获取用于传输目标信道的时域资源，从而在第n+i个时域资源单元中的该频域资源和该时域资源上，向网络设备发送该目标信 道，或者接收网络设备发送的该目标信道。
上述方法可以应用于上行和下行传输的场景，该目标信道可以是数据信道或者控制信道，该数据信道可以是上行数据信道，也可以是下行数据信道，还可以是副链路(sidelink)数据信道。特别地，对于上行数据信道或控制信道的传输，终端设备提前获取携带第一资源指示信息的DCI，可以有充足的时间为上行数据信道的传输做准备，并且通过接收第二资源指示信息获知上行数据信道是否被上下行控制信道占用，以及上行数据信道具体的时域资源位置，使得在进行上行数据信道传输过程不会受到其他控制信道的干扰。
本申请实施例的传输数据的方法，终端设备在接收携带传输资源信息的下行控制信息后，通过接收网络设备补充发送的用于指示传输上/下行信道的资源的指示信息，从而能够在实现提前调度的基础上也能够准确获知用于传输上/下信道的资源位置。
下面以图7至图10中的示例来详细说明本申请实施例的数据传输的方法。图7至图10中是以目标信道为数据信道为例进行说明。
举例来说，如图7所示的PDSCH的资源配置方式。第n+i个时隙中初始的时域资源被下行控制信道PDCCH占用。网络设备在第n个时隙中向终端设备发送第一资源指示信息对PDSCH的传输资源进行调度，但是在第一资源指示信息的发送时刻即T1时刻，PDCCH在第n+i个时隙中占用的时域资源的位置尚未确定，当PDCCH在该时隙中占用的时域资源确定后，网络设备可以在时刻T2发送第二资源指示信息以向终端设备指示用于传输PDSCH的时域资源，从而通过向终端设备补充指示第n+i个时隙中用于传输PDSCH的准确的时域资源，避免了终端设备误将PDCCH当做PDSCH接收的情况发生，从而保证了PDSCH解调和解码性能。
又例如，如图8所示的PDSCH的资源配置方式，第n+i个时隙中初始的时域资源被下行控制信道PDCCH占用，而且该时隙末尾部分的时域资源被上行信道例如PUCCH占用。网络设备在第n个时隙中向终端设备发送第一资源指示信息对PDSCH的传输资源进行调度，但是在第一资源指示信息的发送时刻即T1时刻，第n+i个时隙中是否存在PDCCH和PUCCH，以及该时隙中用于传输PDCCH和PUCCH的时域资源的位置尚未确定，当该时隙中用于传输PDCCH和PUCCH的时域资源的位置确定后，网络设备可以在时刻T2发送第二资源指示信息以向终端设备指示用于传输PDSCH的时 域资源，从而通过向终端设备补充指示第n+i个时隙中用于传输PDSCH的准确的时域资源，避免了终端设备误将PDCCH和PUCCH当做PDSCH接收的情况发生，从而保证了PDSCH解调和解码性能。
又例如，如图9所示的PUSCH的资源配置方式，第n+i个时隙中初始的时域资源和末尾的时域资源可能被上行控制信道PUCCH占用。网络设备在第n个时隙中向终端设备发送第一资源指示信息对PUSCH的传输资源进行调度，但是在第一资源指示信息的发送时刻即T1时刻，PUCCH在第n+i个时隙中占用的时域资源的位置尚未确定，当PUCCH在该时隙中占用的时域资源确定后，网络设备可以在时刻T2发送第二资源指示信息以向终端设备指示用于传输PUSCH的时域资源，从而通过向终端设备补充指示第n+i个时隙中用于传输PUSCH的准确的时域资源，避免了终端设备发送的PUSCH与其他终端设备发送的PUCCH冲突，避免了PDSCH和PUCCH之间的相互干扰，改善了PUSCH和PUCCH的传输性能。
又例如，如图10所示的PUSCH的资源配置方式，第n+i个时隙中的部下时域资源被下行控制信道PDCCH占用，而且第n+i个时隙中的时域资源被PUCCH和PDCCH占用。网络设备在第n个时隙中向终端设备发送第一资源指示信息对PUSCH的传输资源进行调度，但是在第一资源指示信息的发送时刻即T1时刻，第n+i个时隙中是否存在PDCCH和PUCCH，以及该时隙中用于传输PDCCH和PUCCH的时域资源的位置尚未确定，当该时隙中用于传输PDCCH和PUCCH的时域资源的位置确定后，网络设备可以在时刻T2发送第二资源指示信息以向终端设备指示用于传输PUSCH的时域资源，从而通过向终端设备补充指示第n+i个时隙中用于传输PUSCH的准确的时域资源，避免了PUSCH和网络设备发送的下行信道之间的相互干扰，改善了PUSCH和下行信道的传输性能。
图11是根据本申请实施例的传输数据的方法1100的示意性流程图。图11中的传输数据的方法可以由网络设备例如图1中所示的网络设备10执行。如图11所示，该传输数据的具体流程包括：
在1110中，网络设备在第一时刻向终端设备发送第一资源指示信息。
其中，该第一时刻位于第n个时域资源单元，该第一资源指示信息指示第n+i个时域资源单元中用于传输该终端设备的目标信道的频域资源，所述目标信道包括所述终端设备的数据信道或控制信道，n和i为正整数；
具体来说，网络设备在第n个时域资源单元(或称时域调度单位)中的第一时刻上，向终端设备发送第一资源指示信息，而该第一资源指示信息指示的是第n+i个时域资源单元中用于传输所述终端设备的目标信道的频域资源。也就是说，第n个时域资源单元上发送的第一资源指示信息，是用于调度第n+i个时域资源单元上目标信道传输的频域资源的。这种跨时隙调度可以使终端设备有充分的时间为之后的数据传输做准备。
应理解，这里的第n个时域资源单元可以理解为当前的时域资源单元，第n+i个时域资源单元可以该是当前时域资源单元之后的第i个时域资源单元。也就是说，第n个时域资源单元可以由第一时域资源单元代替，第n+i个时域资源单元可以由第二时域资源单元代替，第二时域资源单元是第一时域资源单元之后的任意一个时域资源单元。可选地，如果第二时域资源单元是第一时域资源单元之后第i个时域资源单元，该第一资源指示信息中还可以包括i的值。
可选地，该数据信道包括以下中的任意一种：上行数据信道、下行数据信道和副链路数据信道。
在1120中，网络设备在位于该第一时刻之后的第二时刻，向终端设备发送第二资源指示信息。
其中，该第二资源指示信息指示第n+i个时域资源单元中用于传输该目标信道的时域资源。
可选地，第n+i个时域资源单元中用于传输该目标信道的该时域资源，是网络设备在第一时刻之后确定的。
可选地，该第二资源指示信息为该终端设备的专有信息(UE specific)。
可选地，该第n个时域资源单元包括以下中的任意一种：第n个时隙、第n个迷你时隙和第n个子帧。
可选地，终端设备用于接收该第一资源指示信息的物理信道，与用于接收该第二资源指示信息的物理信道可以不同。
在跨时隙调度中，在第n个时隙，网络设备有可能尚未确定第n+i个时隙中用于传输控制信道或目标信道的时域资源位置，那么网络设备就无法实现提前对第n+i个时隙的目标信道的调度。因而，网络设备可以首先通过第一资源指示信息指示第n+i个时域资源单元中用于传输该目标信道的频域资源，并在第一时刻之后的第二时刻向终端设备配置第n+i个时域资源单元中 用于传输该目标信道的时域资源。在第二时刻网络设备已经确定好第n+i个时域资源单元中用于传输该目标信道的时域资源。
可选地，该第二资源指示信息指示的所述时域资源包括以下中的至少一种：该第n+i个时域资源单元中用于传输该目标信道的符号的起始位置、用于传输该目标信道的符号的数量、用于传输该目标信道的迷你时隙、和用于传输该目标信道的迷你时隙的数量。
具体来说，终端设备接收的该第二资源指示信息，可以指示用于传输目标信道的时域资源在第n+i个时域资源单元中占用的符号的起始位置和/或占用的符号数量；该第二资源指示信息也可以指示用于传输目标信道的时域资源在第n+i个时域资源单元中占用的迷你时隙的起始位置和/或占用的迷你时隙的数量，这时一个时域资源单元中可以包括若干个迷你时隙；如果一个时域资源单元中可以包括若干个迷你时隙，且每个迷你时隙中又包括若干个符号，那么该第二资源指示信息还可以指示用于传输目标信道的时域资源在第n+i个时域资源单元中占用的迷你时隙的信息，以及在该迷你时隙中占用的符号的信息。这里不做限定。
可选地，该第二资源指示信息还可以包括该时域资源的标识，该第二资源指示信息指示的该时域资源为预设的多个时域资源中与该标识对应的时域资源。
也就是说，第n+i个时域资源单元中用于传输目标信道的时域资源，可以是预设的多种时域资源配置中的一种，具体可以通过与时域资源对应的标识来确定。
可选地，该第一资源指示信息还指示该第n+i个时域资源单元中用于传输该目标信道的时域资源。
可选地，该方法还包括：网络设备确定第一资源指示信息指示的时域资源，与第二资源指示信息指示的时域资源是否相同；若第一资源指示信息指示的时域资源，与第二资源指示信息指示的时域资源不同，则网络设备确定使用第二资源指示信息指示的该时域资源传输目标信道。
该实施例中，第一资源指示信息指示的第n+i个时域资源单元中传输目标信道的时域资源，与第二资源指示信息指示的第n+i个时域资源单元中传输数据的时域资源，如果不相同，或者说发生冲突，那么网络设备会将第二资源指示信息指示的该时域资源作为在第n+i个时域资源单元中传输目标信 道的时域资源。
可选地，该方法还包括：网络设备根据第二资源指示信息，在第一资源指示信息指示的时域资源的范围内，确定用于传输目标信道的该时域资源。
该实施例中，第一资源指示信息指示的第n+i个时域资源单元中传输目标信道的时域资源的范围，大于第二资源指示信息指示的第n+i个时域资源单元中传输数据的时域资源。网络设备可以通过第一资源指示信息先向终端设备指示一个大致的时域资源的范围，并在具体确定了第n+i个时域资源单元中传输目标信道的时域资源后，再通过第二资源指示信息指示第n+i个时域资源单元中传输目标信道的具体的时域资源位置。
可选地，在1120中网络设备在位于该第一时刻之后的第二时刻，向终端设备发送第二资源指示信息，包括：网络设备在位于第一时刻之后的第二时刻，在预设的频域资源上，向终端设备发送该第二资源指示信息。
即，网络设备用于发送第二资源指示信息的时频资源是预先约定的。例如第二资源指示信息的时频资源位置可以和发送第一资源指示信息的时频资源位置之间存在固定的位置关系。网络设备发送第一资源指示信息之后，就会在响应的时频资源上发送第二资源指示信息。其中，发送该第二资源指示信息的时域资源即该第二时刻。
进一步地，可选地，第一资源指示信息包括用于接收第二资源指示信息的该第二时刻和该预设的频域资源，在网络设备向终端设备发送第二资源指示信息之前，该方法还包括：网络设备确定用于接收第二资源指示信息的第二时刻和该预设的频域资源。
即，网络设备发送第二资源指示信息的时频资源的信息，是携带在第一资源指示信息中一起指示给终端设备的。终端设备在第一时刻接收第一资源指示信息后，不仅可以从第一资源指示信息中获取第n+i个时域资源单元中用于传输目标信道的频域资源，还可以从第一资源指示信息中获取用于接收第二资源指示信息的时域资源即第二时刻和频域资源，从而终端设备进一步从第二时刻接收的第二资源指示信息中获取第n+i个时域资源单元中用于传输目标信道的时域资源。
可选地，在1120之后，该方法还包括1130。
在1130中，网络设备在该第n+i个时域资源单元中的该频域资源和该时域资源上，接收终端设备发送的该目标信道，或者向终端设备发送该目标 信道。
本申请实施例的传输数据的方法，网络设备在向终端设备发送携带传输资源信息的下行控制信息后，通过向终端设备补充发送的用于指示传输上/下信道的资源指示信息，从而能够在实现提前对终端设备进行资源调度的基础上，使终端设备也能够准确获知用于传输上/下信道的资源位置。
网络设备通过第一资源指示信息和第二资源指示信息为终端设备配置传输资源的情况，可以参考前述图7至图10的描述，为了简洁，这里不再赘述。
应理解，本申请实施例中，网络设备向终端设备发送的第一资源指示信息和第二资源指示信息，指示的都是时域资源单元中用于传输目标信道的时域资源，这里的“指示”可以是直接指示或者间接指示。例如，网络设备可以在第二资源指示信息中直接携带传输目标信道的时域资源的信息，从而直接向终端设备指示时域资源单元中用于传输目标信道的时域资源；或者，网络设备也可以在第二资源指示信息中携带该时隙中被其他信道占用的时域资源，从而终端设备可以根据时域资源单元中被占用的时域资源，来推断该时域资源单元中用于传输目标信道的时域资源，比如第二资源指示信息中携带第n+i个时隙中用于传输PDCCH的符号位置，那么终端设备就可以根据传输PDCCH的符号位置，推断出该时隙中的剩余符号是用于传输PDSCH的。
还应理解，本申请实施例中，网络设备还可以同时向终端设备指示多个时域资源单元中传输目标信道的时域资源。网络设备可以在第一时刻向终端设备发送第一资源指示信息，第一资源指示信息可以指示位于第n个时域资源单元之后的K个时域资源单元中的每个时域资源单元上用于传输终端设备目标信道的频域资源(K≥1)。网络设备在第一时刻之后的第二时刻向终端设备发送第二资源指示信息，第二资源指示信息指示第n+i个时域资源单元中用于传输目标信道的时域资源；网络设备还可以在第一时刻之后的第三时刻向终端设备发送第三资源指示信息，第三资源指示信息指示第n+k个时域资源单元中用于传输所述目标信道的时域资源，k≠i。
例如图12所示的PDSCH的多时隙资源配置(slot aggregation)的示意图。时隙1至时隙3中的时域资源均被下行控制信道PDCCH占用。网络设备在时隙1中向终端设备发送第一资源指示信息对时隙1至时隙3中PDSCH 的传输资源进行调度，但是在第一资源指示信息的发送时刻即T1时刻，时隙2和时隙3的PDCCH占用的时域资源的位置尚未确定。当PDCCH在时隙2中占用的时域资源确定后，网络设备可以在时刻T2′发送第二资源指示信息以向终端设备指示时隙2中用于传输PDSCH的时域资源，从而通过向终端设备补充指示时隙2中用于传输PDSCH的准确的时域资源；当PDCCH在时隙3中占用的时域资源确定后，网络设备可以在时刻T2"发送第三资源指示信息以向终端设备指示时隙3中用于传输PDSCH的时域资源，从而通过向终端设备补充指示时隙3中用于传输PDSCH的准确的时域资源，避免了终端设备误将PDCCH当做PDSCH接收的情况发生，从而保证了PDSCH解调和解码性能。
应理解，在本申请的各种实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
图13是根据本申请实施例的终端设备1300的示意性框图。如图13所示，该终端设备1300包括接收单元1310和发送单元1320。其中：
该接收单元1310用于：用于在第一时刻接收网络设备发送的第一资源指示信息，所述第一时刻位于第n个时域资源单元，所述第一资源指示信息指示第n+i个时域资源单元中用于传输目标信道的频域资源，所述目标信道包括所述终端设备的数据信道或控制信道，n和i为正整数；
所述接收单元1310还用于，在位于所述第一时刻之后的第二时刻，接收所述网络设备发送的第二资源指示信息，所述第二资源指示信息指示所述第n+i个时域资源单元中用于传输所述目标信道的时域资源。
因此，终端设备在接收携带传输资源信息的下行控制信息后，通过接收网络设备补充发送的用于指示传输上/下行信道的资源的指示信息，从而能够在实现提前调度的基础上也能够准确获知用于传输上/下信道的资源位置。
可选地，所述第n+i个时域资源单元中用于传输所述目标信道的所述时域资源，是所述网络设备在所述第一时刻之后确定的。
可选地，所述发送单元1320用于：在所述第n+i个时域资源单元中的所述频域资源和所述时域资源上，向所述网络设备发送所述目标信道；
