Description

数据传输方法、装置、系统及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种数据传输方法、装置、系统及存储介质。
背景技术
在新无线技术(New Radio，NR)中，为了保证覆盖范围以及抵抗路径损耗，通常需要基于波束(beam)进行数据传输。
基于波束进行数据传输过程中，网络设备(例如基站)通过信令指示传输配置指示(Transmission Configuration Indication，TCI)状态或空间关系信息(spatialrelationinfo)，进而指示终端的接收波束或发送波束。其中，每个TCI状态或每个空间关系信息对应一个参考信号(Reference Signal，RS)标识，该RS既可以是非零功率信道状态信息参考信号(channel state information reference signal，CSI-RS)，也可以是同步信号块(Synchronization Signal Block，SSB)，或是探测参考信号(sounding reference signal，SRS)。从而通过TCI状态或空间关系信息可以告知终端接收物理下行控制信道(physical downlink control channel，PDCCH)/物理下行共享信道(physical downlink shared channel，PDSCH)使用与接收基站发送的哪个SSB或CSI-RS一样的接收波束，或使用与发送哪个SRS一样的发送波束对应的接收波束；或告知终端发送物理上行控制信道(physical uplink control channel，PUCCH)/物理上行共享信道(physical uplink shared channel，PUSCH)使用与发送哪个SRS一样的发送波束，或使用与接收哪个CSI-RS或SSB一样的接收波束对应的发送波束。
未来多输入多输出(Multiple-Input Multiple-Output，MIMO)支持基于多个传输接收点(Transmission Reception Point，TRP)或多个天线面板(panel)的数据传输，即需要使用多个波束方向同时进行发送接收。每个TRP或panel均支持多个数据流的传输。多个数据流之间可以有不同的组合方式。
然而，采用多个波束方向进行发送接收时，如果终端没有正确获取基站指示的各个数据流对应的接收波束或发送波束，则会出现数据在终端或基站端接收失败的情形，导致吞吐量降低。

进一步的，本公开中涉及的终端120，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
本公开中网络设备110与终端120之间基于波束进行数据传输。基于波束进行数据传输过程中，网络设备110使用多个TRP/panel同时进行发送，每个TRP/panel使用一个发送波束方向进行数据发送，相应的，终端120需要同时使用多个panel进行接收，每个panel使用一个接收波束来进行数据接收。针对基于波束的接收过程，TCI状态或空间关系信息用于告知终端120在接收PDCCH/PDSCH时，具体是使用接收网络设备110发送的哪个SSB或CSI-RS时一样的接收波束，或者是使用与终端发送哪个SRS时一样的发送波束对应的接收波束。
相关技术中，网络设备110通过下行控制信息(Downlink Control Information，DCI) 信令指示TCI状态或空间关系信息。TCI状态或空间关系信息可以作为波束指示信息用于指示波束方向，本公开中波束方向包括上行波束方向和下行波束方向。当数据流是下行数据流时，波束方向对应下行接收波束方向，用于表征各个数据流的下行接收波束；当数据流是上行数据流时，波束方向对应上行波束方向，用于表征数据流的上行发送波束。
以PDSCH为例，对于一个PDSCH若包含两个数据流的传输，不同的数据流传输不同的传输块(transport block，TB)，但不同的TB若由同一个TRP的同一个panel发送，则二者对应的TCI状态是一致的。以这两个TB分别为TB1和TB2为例，则相应的DCI信令可如下所示：
For transport block 1:
-Modulation and coding scheme–5bits as defined in Subclause x.x of[6,TS 38.214]
-New data indicator–1bit
-Redundancy version–2bits as defined in Table 7.3.1.1.1-2
For transport block 2(only present if Number-MCS-HARQ-DL-DCI equals 2):
-Modulation and coding scheme–5bits as defined in Subclause x.x of[6,TS 38.214]
-New data indicator–1bit
-Redundancy version–2bits as defined in Table 7.3.1.1.1-2
……
-Transmission configuration indication–0bit if higher layer parameter tci-PresentInDCI is not enabled；otherwise 3 bits as defined in Subclause x.x of[6,TS38.214].
由上述DCI信令可知，TB1和TB2虽然由不同的数据流传输，但对应相同的TCI状态，即网络设备110告知终端120使用同一个接收波束来接收这两个数据流的TB。
TCI状态如下表1所示，终端120通过TCI状态可确定出接收波束。

相关技术中，通过码字(codepoint)指示TCI状态或空闲关系信息，一个TCI码字或空间关系信息码字最多可以指示两个TCI状态或两个空间关系信息，即指示两个传输接收点(Transmission Reception Point，TRP)/天线面板(panel)的波束方向。
通常，一个DCI指示中最多可以指示来自两个TRP/panel的多个数据流，例如可以指示来自两个TRP或panel的最多4个数据流。这最多4个数据流可以有不同的组合形式，每一组合可分别属于两个TRP/panel中的任一TRP/panel，故对于终端而言其并不能确定各个数据流组合具体来自于哪个TRP/panel，进而造成数据流接收失败，数据接收成功率较低，吞吐量较低的情形。例如，一个DCI指示的最多4个数据流的组合形式可以有“1个数据流+1个数据流”，“1个数据流+2个数据流”，“2个数据流+1个数据流”，“2个数据流+2个数据流”，“1个数据流+3个数据流”，“3个数据流+1个数据流等组合”。
对于以上组合，如果网络设备110没有额外信令指示，网络设备110和终端120之间没有歧义的是组合“1个数据流+1个数据流”，即当指示了两个数据流时，肯定是每个数据流对应一个TRP/panel。如果不支持“1个数据流+3个数据流”，“3个数据流+1个数据流”，则“2个数据流+2个数据流”配置也没有歧义，即当指示了4个数据流时，肯定是每2个数据流对应一个TRP/panel。
存在歧义的组合：当指示了3个数据流时，到底是“1个数据流+2个数据流”的组合，即第一个数据流对应第一个TRP/panel、后两个数据流对应第二个TRP/panel；还是“2个数据流+1个数据流”即前两个数据流对应第一个TRP/panel、最后一个数据流对应第二个TRP/panel。另外，如果“1个数据流+3个数据流”，“3个数据流+1个数据流”也支持时，存在歧义的组合还有：当指示了4个数据流时，可能是3种组合：“1个数据流+3个数据流”，“3个数据流+1个数据流”，“2个数据流+2个数据流”。如果终端120不能准确的获知到底是哪种组合，则无法获得某些数据流的正确的接收配置信息比如TCI状态，而使用了错误的TCI状态，导致数据接收失败，降低吞吐量。
同样，对于PUSCH的传输也是如此，当终端需要发送多个数据流给网络设备时，每个数据流使用哪个发送波束也是必须由网络设备明确指示给终端的，否则如果网络设备指示终端使用第一波束方向发送第二数据流，而终端使用的是第二波束方向发送的第二数据流，但网络设备会使用第一波束方向相应的波束方向来接收第二数据流，那么终端与网络设备的不一致就会导致网络设备的接收失败，降低吞吐量。而网络设备指示发送波束给终 端时，可以使用TCI状态或空间关系信息来指示。
为此，在诸如基于多个TRP/panel的数据传输中不同TB由不同TRP/panel发送的情况下，为使终端准确获知TCI状态或空间关系信息，并准确确定出数据流组合中各数据流的波束方向，进而使用该确定的波束方向对应的波束传输数据流。本公开提供一种数据传输方法，在该数据传输方法中，通过指示数据流组合的指示信令，使得终端根据所述指示信令指示的数据流组合，确定传输所述数据流组合中各数据流的波束，并使用确定的波束传输所述数据流组合中各数据流。
可以理解的是，本公开涉及的传输数据流组合中各数据流可以全是终端需要发送的数据流组合中各数据流，也可以全是终端需要接收的数据流组合中各数据流。传输数据流组合中各数据流的波束可以全是终端的接收波束，也可以全是终端的发送波束。
本公开中终端根据指示数据流组合的指示信令，可以准确确定出终端需要接收的数据流组合中各数据流的接收波束，并使用所述接收波束接收所述数据流组合中各数据流。或者终端根据指示数据流组合的指示信令，可以准确确定出终端需要发送的数据流组合中各数据流的发送波束，并使用所述发送波束发送所述数据流组合中各数据流，提高数据接收成功率，提高吞吐量。
图2是根据一示例性实施例示出的一种数据传输方法的流程图，如图1所示，该数据传输方法用于网络设备中，包括以下步骤S11和步骤S12。
在步骤S11中，确定指示信令。
本公开中，确定的指示信令用于指示数据流组合。数据流组合中包括多个数据流，多个数据流划分为至少两个数据流组。所述至少两个数据流组中每一数据流组的数据流对应一个波束方向。例如，数据流组合为“1个数据流+3个数据流”，则该数据流组合中包括4个数据流。4个数据流被划分为两组，分别为“1个数据流组和3个数据流组”，且1个数据流组对应一个波束方向(来自同一TRP/panel)，3个数据流组对应一个波束方向(来自同一TRP/panel)。
需要说明的是，一个DCI信令调度的所有数据流可能全是下行数据流，则每个数据流组合对应一个终端的接收波束方向。一个DCI信令调度的所有数据流也可能全是上行数据流，则每个数据组合对应一个终端的发送波束方向。
在步骤S12中，发送指示信令。
本公开中，网络设备发送指示信令，接收到该指示信令的终端，可以依据该指示信令所指示的数据流组合确定数据流组合中每一数据流组对应的波束方向，进而可确定接收数 据流组合中各数据流组的接收波束，并使用接收波束接收数据流组合中各数据流，提高数据接收成功率，或确定发送数据流组合中各数据流组的发送波束，并使用发送波束发送数据流组合中的各数据流，提高吞吐量。
本公开实施例以下将对网络设备发送指示信令的示例性实施例进行说明。
一示例性实施例中，通过DCI发送指示信令。
本公开中指示信令可以是DCI信令，通过DCI信令中包括的比特位取值指示数据流组合，不同比特位值用于指示不同的数据流组合。若终端能够确定所有的数据流组合，并保存有比特位取值与数据流组合之间的对应关系，则在获取到通过DCI发送的比特位取值后，确定数据流组合。
其中，终端支持的所有数据流组合可由网络设备通过无线资源控制(Radio Resource Control，RRC)信令告知，或者也可采用系统预定义的方式在终端和网络设备上保存支持的所有数据流组合。
一实施例中，可通过1个比特位的不同比特位值指示两个不同的数据流组合。例如，支持的数据流最多为4个，在支持的所有数据流组合中不包含“1个数据流+3个数据流”以及“3个数据流+1个数据流”这两种数据流组合之际，本公开中可指示当数据流为3时的组合方式：“1个数据流+2个数据流”还是“2个数据流+1个数据流”，即通过1个比特位来指示，不同的比特位值对应不同的数据流组合。比如该比特位值为“0”时，表示“2个数据流+1个数据流”的组合方式，该比特位值为“1”时，表示“1个数据流+2个数据流”的组合方式。当然，本公开中并不限定比特位值与组合方式之间的对应关系，例如也可以是比特位值为“1”时，表示“2个数据流+1个数据流”的组合方式，该比特位值为“0”时，表示“1个数据流+2个数据流”的组合方式。
本公开中为描述方便，将通过一个比特位指示数据流组合的DCI称为第一DCI，该比特位称为第一比特位。其中，第一DCI中包括第一比特位。第一比特位中包括的比特位数量为1。第一比特位的不同比特位值用于指示不同的数据流组合。
本公开中该第一比特位可以为第一DCI中单独用来指示数据流组合的比特位，也可以是第一DCI中包括有预留比特位值的比特位。其中预留的比特位值指示数据流组合，已占用的比特位值可指示不同于数据流组合的其它信息，例如可以是指示天线端口信息。
本公开中网络设备通过发送第一DCI发送指示信令，可使接收到该第一DCI的终端通过比特位取值确定数据流组合方式，进而确定波束方向。
另一实施例中，本公开中可通过多个比特位中的不同比特位取值指示不同的数据流组 合。例如，支持的数据流最多为4个，在支持的所有数据流组合中包括“1个数据流+2个数据流”，“2个数据流+1个数据流”，“2个数据流+2个数据流”，“1个数据流+3个数据流”，“3个数据流+1个数据流”等组合之际，除了需要指示当数据流为3时的数据流组合是“1个数据流+2个数据流”和“2个数据流+1个数据流”中的一个，还要指示当数据流为4时的数据流组合方式是“2个数据流+2个数据流”，“1个数据流+3个数据流”，“3个数据流+1个数据流”中的一个。本公开中可通过至少2个比特位中的不同比特位取值指示支持最多4个数据流中的数据流组合。
一方面，本公开中，在支持的数据流数量为最多3个时，可通过多个比特位中的一个比特位的不同比特位取值指示不同的数据流组合。例如本公开中可通过两个比特位中的低比特位或高比特位的不同取值指示“1个数据流+2个数据流”和“2个数据流+1个数据流”。例如，两个比特位中的低比特位的取值为“0”时，表示“2个数据流+1个数据流”的组合方式。两个比特位中的低比特位值为“1”时，表示“1个数据流+2个数据流”的组合方式。当然，本公开中并不限定比特位值与组合方式之间的对应关系，例如也可以是两个比特位中的低比特位值为“1”时，表示“2个数据流+1个数据流”的组合方式，该两个比特位中的低比特位值为“0”时，表示“1个数据流+2个数据流”的组合方式。
另一方面，本公开中，在支持的数据流数量为最多4个时，可通过多个比特位中的两个比特位的不同比特位取值指示不同的数据流组合。例如，本公开中可通过两个比特位的不同比特位值指示“1个数据流+2个数据流”、“2个数据流+1个数据流”、“2个数据流+2个数据流”，“1个数据流+3个数据流”，“3个数据流+1个数据流”。例如，两个比特位的比特位值为“00”时，表示“1个数据流+3个数据流”的组合方式。两个比特位的比特位值为“01”时，表示“2个数据流+2个数据流”的组合方式。两个比特位的比特位值为“10”时，表示“3个数据流+1个数据流”的组合方式。当然，本公开中并不限定比特位值与数据流组合方式之间的对应关系，也可以是其他的对应关系。例如也可以是两个比特位中的比特位值为“11”时，表示“3个数据流+1个数据流”的组合方式。
本公开中为描述方便，可将包括多个比特位的DCI称为第二DCI，第二DCI中包括第二比特位，所述第二比特位中包括的比特位数量可以为2。第二比特位中一个比特位的不同比特位取值用于指示不同的数据流组合；或者第二比特位中全部比特位的不同比特位取值用于指示不同的数据流组合。
本公开中第二比特位的一个或多个比特位为第二DCI中包括有预留比特位值的比特 位。其中预留的比特位值指示数据流组合，已占用的比特位值可指示不同于数据流组合的其它信息，例如可以是指示天线端口信息。
本公开中网络设备通过第二DCI发送指示信令，可使接收到该第一DCI的终端通过比特位取值确定数据流组合方式，进而确定波束方向。
另一示例性实施例中，通过RRC信令发送指示信令。
一实施例中，本公开中可在RRC信令进行TRP/panel配置时，配置多个TRP/panel支持的多个数据流组合。通过RRC信令指示至少一个数据流组合。比如本公开中配置两个TRP/panel支持的数据流组合。例如支持的数据流组合为“1个数据流+1个数据流”、“2个数据流+2个数据流”、“1个数据流+2个数据流”。
进一步的，本公开中可TRP/panel支持的数据流组合发生变化后，通过RRC重配置信令改变已配置的数据流组合。例如，一段时间之后需要改变支持的组合，则使用RRC重配置信令对组合进行改变，比如支持的数据流组合由{“1个数据流+1个数据流”、“2个数据流+2个数据流”、“1个数据流+2个数据流”}改变为{“1个数据流+1个数据流”、“2个数据流+2个数据流”、“2个数据流+1个数据流”}，或者也可以采用去除“1个数据流+2个数据流”，添加“2个数据流+1个数据流”的方式进行RRC信令配置。
本公开中可通过单独的RRC信令指示数据流组合，本公开中将该单独用于指示至少一个数据流组合的RRC信令称为第一RRC信令。网络设备通过发送第一RRC信令发送指示数据流组合的指示信令。网络设备在调度资源时，会发送DCI信令用来指示数据流的数目以及2个波束方向。若数据流为下行数据流，则接收到该第一RRC信令的终端可通过该第一RRC信令和DCI调度信令中的数据流数目以及2个波束方向来确定接收数据流组合中各数据流的接收波束，并使用接收波束接收数据流组合中各数据流。若数据流为上行数据流，则接收到该第一RRC信令的终端可通过该第一RRC信令和DCI调度信令中的数据流数目以及2个波束方向来确定发送数据流组合中各数据流的发送波束，并使用发送波束发送数据流组合中各数据流。
又一示例性实施例中，通过RRC信令和媒体接入控制(Media Access Control，MAC)信令发送指示信令。
本公开中，可通过RRC信令指示N个可能支持的数据流组合集合，其中，N为大于等于1的正整数。通过MAC信令激活N个数据流组合中的至少一个数据流组合集合。
一实施例中，RRC信令指示的N个可能支持的数据流组合集合中的每一数据流组合集合中包括一个数据流组合，即RRC信令指示N个支持的数据流组合。MAC信令包括 N个比特位，每一比特位对应一个数据流组合，通过置位比特位激活至少一个数据流组合。例如支持的数据流组合数量N为6，分别为“1个数据流+1个数据流”，“1个数据流+2个数据流”，“2个数据流+1个数据流”，“2个数据流+2个数据流”，“1个数据流+3个数据流”，“3个数据流+1个数据流”等组合。MAC信令有6个比特位，每个比特位对应一个数据流组合，当比特位被置位时激活对应的数据流组合。例如，针对一种数据流组合，当数据流组合对应的比特位被置位为“1”时，表示该数据流组合被激活，接下来终端可使用该激活的数据流组合确定波束方向。比如RRC信令指示出了上述6种数据流组合中的全部数据流组合，N为6，则MAC信令中包括6个比特位。6个比特位中的最高位即最左边的位对应“1个数据流+1个数据流”……最低位即最右边的位对应“3个数据流+1个数据流”。当MAC信令中的比特位显示110100，则是激活“1个数据流+1个数据流”，“1个数据流+2个数据流”，“2个数据流+2个数据流”这三种数据流组合方式。
另一实施例中，MAC信令可包括M个比特位，M个比特位至少能指示N个比特位取值，每一比特位取值对应激活一个数据流组合集合，所述M为大于等于1的正整数。例如，RRC信令指示出了上述6种数据流组合中的全部数据流组合，N为6，则M取值可为3。通过3个比特位的不同比特位取值指示6种数据流组合中的不同数据流组合。比如，“000”对应“1个数据流+1个数据流”，“001”对应“1个数据流+2个数据流”。其中，比特位取值与数据流组合之间具有一一对应关系，该一一对应关系需要保存在网络设备和终端中。通过比特位取值激活数据流组合集合。每一比特位取值对应激活一个数据流组合集合。
本公开中通过MAC信令激活RRC信令指示的多个数据流组合集合中的数据流组合集合的方式。如果MAC信令激活的数据流组合数量为多个，并且能明确指示出当前使用的数据流组合，那么MAC信令同时激活的数据流组合有限制，即MAC信令不能同时激活存在歧义的数据流组合。比如“1个数据流+2个数据流”和“2个数据流+1个数据流”这两种组合方式不能同时被激活；又比如“1个数据流+3个数据流”，“3个数据流+1个数据流”，和“2个数据流+2个数据流”这三种数据流组合方式也不能同时激活，同时最多激活一种。
本公开中，如果RRC信令给出有限的几种数据流组合集合，并且该数据流组合集合中不存在有歧义的组合，则MAC信令可激活其中一种。不存在歧义组合是指“1个数据流+2个数据流”和“2个数据流+1个数据流”这两种组合方式不同时出现在一个组合集 合中；又比如“1个数据流+3个数据流”，“3个数据流+1个数据流”，和“2个数据流+2个数据流”这三种数据流组合中任意两种或以上也不能同时出现在一个组合集合里。比如RRC信令给出组合集合1：{“1个数据流+1个数据流”，“1个数据流+2个数据流”，“2个数据流+2个数据流”}，组合集合2：{“1个数据流+1个数据流”，“2个数据流+1个数据流”，“2个数据流+2个数据流”}，组合集合3：{“1个数据流+1个数据流”，“1个数据流+2个数据流”，“1个数据流+3个数据流”}；组合集合4：{“1个数据流+1个数据流”，“2个数据流+1个数据流”，“1个数据流+3个数据流”}，组合集合5：{“1个数据流+1个数据流”，“1个数据流+2个数据流”，“3个数据流+1个数据流”}；组合集合6：{“1个数据流+1个数据流”，“2个数据流+1个数据流”，“3个数据流+1个数据流”}……。那么MAC信令可针对RRC信令指示的数据流组合集合中的一个数据流组合集合进行激活。
又一示例性实施例中，通过RRC信令、MAC信令和DCI信令发送指示信令。
本公开在上述通过RRC信令和MAC信令进行指示信令发送的实施方式中，若MAC信令激活的数据流组合集合中包括多个数据流组合，并不能明确确定激活的数据流组合，可通过DCI信令指示所述MAC信令激活的数据流组合集合中的一个数据流组合。例如，当MAC信令激活的数据流组合中同时存在“1个数据流+2个数据流”和“2个数据流+1个数据流”的组合，或同时存在“1个数据流+3个数据流”，“3个数据流+1个数据流”和“2个数据流+2个数据流”中的两种组合或三种组合时，需要通过DCI信令指示所述MAC信令激活的多个数据流组合中的一个数据流组合。比如，MAC信令激活的数据流组合集合为{“1个数据流+2个数据流”，“2个数据流+1个数据流”}，则需要通过DCI信令指示“1个数据流+2个数据流”或“2个数据流+1个数据流”。再例如MAC信令激活的数据流组合集合为{“1个数据流+3个数据流”，“3个数据流+1个数据流”，“2个数据流+2个数据流”}，则需要通过DCI信令指示“1个数据流+3个数据流”，“3个数据流+1个数据流”和“2个数据流+2个数据流”这三个数据流组中的一个。
本公开中可将该用于指示MAC信令激活的数据流组合集合中的一个数据流组合的DCI称为第三DCI。通过第三DCI发送指示信令。第三DCI用于指示MAC信令激活的数据流组合集合中的一个数据流组合。接收到该第三DCI的终端可明确确定出数据流组合。
图3是根据一示例性实施例示出的一种数据传输方法的流程图，如图2所示，该数据传输方法用于终端中，包括以下步骤S21和步骤S22。
在步骤S21中，接收指示信令。
本公开中，指示信令用于指示数据流组合，所述数据流组合中包括多个数据流，所述多个数据流划分为至少两个数据流组，所述至少两个数据流组中每一数据流组的数据流对应一个波束方向。
本公开中，可通过第一DCI接收指示信令，也可通过第二DCI接收指示信令，还可通过第一RRC信令接收指示信令，或者也可以通过第二RRC信令和MAC信令接收指示信令，或者还可通过接收第二RRC信令、MAC信令和第三DCI接收指示信令。
在步骤S22中，根据指示信令指示的数据流组合，确定传输数据流组合中各数据流的波束，并使用确定的波束传输数据流组合中各数据流。
一种实施方式中，接收指示信令包括：通过第一下行控制信息DCI接收所述指示信令。所述第一DCI中包括第一比特位，所述第一比特位中包括的比特位数量为1；所述第一比特位的不同比特位值用于指示不同的数据流组合。
另一种实施方式中，所述第一比特位为第一DCI中包括有预留比特位值的比特位。
又一种实施方式中，接收指示信令，包括：通过第二下行控制信息DCI接收指示信令。所述第二DCI中包括第二比特位，所述第二比特位中包括的比特位数量为2；所述第二比特位中一个比特位的不同比特位取值用于指示不同的数据流组合；或者所述第二比特位中全部比特位的不同比特位取值用于指示不同的数据流组合。
又一种实施方式中，所述第二比特位中的一个或多个比特位为所述第二DCI中包括有预留比特位值的比特位。
又一种实施方式中，接收指示信令，包括：通过第一无线资源控制RRC信令接收指示信令。所述第一RRC信令用于指示至少一个数据流组合。
又一种实施方式中，接收指示信令，包括：通过第二无线资源控制RRC信令和媒体接入控制MAC信令接收指示信令；所述第二RRC信令用于指示N个数据流组合集合，所述MAC信令用于激活N个数据流组合集合中的至少一个数据流组合集合，所述N为大于等于1的正整数。
又一种实施方式中，所述N个数据流组合集合中每一数据流组合集合中包括一个数据流组合，所述MAC信令包括N个比特位，每一比特位对应一个数据流组合，通过置位比特位激活至少一个数据流组合。
又一种实施方式中，所述MAC信令包括M个比特位，M个比特位至少能指示N个比特位取值，每一比特位取值对应激活一个数据流组合集合，所述M为大于等于1的正 整数。
又一种实施方式中，接收指示信令，还包括：通过第三下行控制信息DCI接收指示信令。所述第三DCI用于指示所述MAC信令激活的一个数据流组合集合中的一个数据流组合。例如，当MAC信令激活的数据流组合中同时存在“1个数据流+2个数据流”和“2个数据流+1个数据流”的组合，或同时存在“1个数据流+3个数据流”，“3个数据流+1个数据流”和“2个数据流+2个数据流”中的两种组合或三种组合时，需要通过第三DCI指示所述MAC信令激活的多个数据流组合中的一个数据流组合。
本公开中终端接收到指示信令后，可通过指示信令指示的数据流组合确定出TCI状态或空间关系信息，进而确定出接收数据流组合中各数据流的接收波束或发送波束，并使用接收波束接收数据流组合中各数据流，或者使用发送波束发送数据流组合中各数据流。
可以理解的是，本公开中终端接收的指示信令和网络设备发送的指示信令相同，故对于此处描述的不够详尽的地方，可参阅上述实施例中的相关描述，在此不再赘述。
图4是根据本公开示例性实施例提供的又一种数据传输方法流程图。图4所示的方法中，由网络设备和终端相互交换进行数据传输，参阅图4所示，该数据传输方法包括如下步骤S301。
在步骤S301中，网络设备确定并发送指示信令。该指示信令用于指示数据流组合。
其中，网络设备可通过第一DCI发送指示信令，也可通过第二DCI发送指示信令，还可通过第一RRC信令发送指示信令，或者也可以通过第二RRC信令和MAC信令发送指示信令，或者还可通过发送第二RRC信令、MAC信令和第三DCI发送指示信令。

在步骤S302中，终端根据接收到指示信令指示的数据流组合，确定传输数据流组合中各数据流的波束，并使用确定的波束传输数据流组合中各数据流。
本公开提供的数据传输方法，网络设备通过发送指示有数据流组合的指示信令，使得终端可根据该指示信令确定出数据流组合，进而确定出传输数据流组合中各数据流的波束，并使用确定的波束传输所述数据流组合中各数据流，可准确进行数据流的发送或接收，提高数据流发送或接收准确度并提高吞吐量。
基于相同的构思，本公开实施例还提供一种数据传输装置。
可以理解的是，本公开实施例提供的数据传输装置为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。结合本公开实施例中所公开的各示例的单元及算法步骤，本公开实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能，但是这种实现不应认为超出本公开实施例的技术方案的范围。
图5是根据一示例性实施例示出的一种数据传输装置500框图。该数据传输装置500可应用于网络设备。数据传输装置500可以是基站等。其中，数据传输装置500包括确定单元501和发送单元502。其中，确定单元501，被配置为确定指示信令。其中，指示信令用于指示数据流组合，数据流组合中包括多个数据流，多个数据流划分为至少两个数据流组。至少两个数据流组中每一数据流组的数据流对应一个波束方向。发送单元502，被配置为发送所述指示信令。
