Description

一种数据传输方法和设备 技术领域
本申请实施例涉及通信领域，尤其涉及一种数据传输方法和设备。
背景技术
在通信系统中，通常一个控制信息(control information，CI)调度一个传输块(transport block，TB)。数据信道可以是物理下行数据信道或物理上行数据信道。
为了降低CI传输的开销，节省传输资源，可以使用一个CI调度多个数据信道，或者使用一个CI调度多个传输块。
当一个CI调度多个传输块时，该CI需要指示调度的传输块的数目和指示每个传输块是否成功接收。例如，一个CI调度8个传输块时，CI需要8个比特按照位图指示方式指示调度的传输块的个数，还需要8个比特指示按照位图指示方式指示每个传输块是否成功接收，这样最大需要8+8＝16比特的指示开销。
由此可见，在现有技术中，一个CI调度多个传输块时，该CI需要指示的信息更多，因此需要的指示开销更大。
上述现有技术中，CI调度传输块的比特开销过大，特别考虑到高可靠性的控制信道性能，太多的比特开销需要消耗更多的传输资源，如何降低CI调度传输块的指示开销仍有待解决。
发明内容
本申请实施例提供了一种数据传输方法和设备，用于降低CI调度传输块的指示开销，减少对传输资源的占用。
为解决上述技术问题，本申请实施例提供以下技术方案：
第一方面，本申请实施例提供一种数据传输方法，包括：第一通信设备接收第二通信设备发送的标识信息；所述标识信息指示一个控制信息能够用于多个传输块的调度时，所述第一通信设备获取所述第二通信设备发送的传输块分配信息，其中所述传输块分配信息指示了所述控制信息调度的传输块个数N和每个传输块对应的比特状态；所述第一通信设备根据所述标识信息和所述每个传输块对应的比特状态，使用所述控制信息指示的至少一个传输块，向所述第二通信设备发送数据,或者接收所述第二通信设备发送的数据，所述至少一个传输块属于所述N个传输块；或者，所述标识信息指示一个控制信息只能用于一个传输块的调度时，所述第一通信设备获取所述第二通信设备发送的混合自动重发请求HARQ进程索引信息，其中所述HARQ进程索引信息指示了所述控制信息调度的一个传输块对应的HARQ进程索引；所述第一通信设备根据所述标识信息和所述一个传输块对应的HARQ进程索引，向所述第二通信设备发送数据，或者接收所述第二通信设备发送的数据。

为解决现有技术中CI调度传输块的指示开销过大问题，本申请实施例提出如下的数据传输方法，适用于控制信息调度传输块场景中，本申请实施例中控制信息具体可以包括下行控制信息。本申请实施例中第二通信设备生成标识信息，该标识信息的指示作用有两种：一种是指示一个控制信息能够用于多个传输块的调度，另一种是指示一个控制信息只能用于一个传输块的调度。当标识信息用于指示一个控制信息能够用于多个传输块的调度时，执行图2所示的交互流程，当标识信息用于指示一个控制信息只能用于一个传输块的调度时，执行图3所示的交互流程。
首先请参阅图2所示，为本申请实施例提供的网络设备和终端设备之间的一种交互流 程示意图，本申请实施例提供的数据传输方法，主要包括如下步骤：
201、第二通信设备生成标识信息。
例如，标识信息可以用于指示一个控制信息能够用于多个传输块的调度，或者可以用于指示一个控制信息只能用于一个传输块的调度。
在本申请实施例中，控制信息由第二通信设备生成，第二通信设备通过控制信息向第一通信设备下发控制指令，后续举例中该控制信息用CI表示。例如，第二通信设备确定用于数据传输的传输块(transport block，TB)个数(number)。例如，第二通信设备确定的传输块个数可以是1个或者多个，多个传输块指的是2个或者3个或者4个…、或者8个传输等。在第二通信设备通过控制信息调度多个传输块时，第二通信设备还需要确定控制信息调度的所有传输块中新传的传输块，和/或重传的传输块。其中，控制信息确定调度的所有传输块中可以是全部新传的传输块，也可以是重传的传输块，或者所有的传输块中有的传输块是新传，有的传输块为重传。
举例说明如下，如图4a所示，控制信息可以调度8个传输块，分别为TB1、TB2…、TB7、TB8。又如图4b所示，控制信息可以调度4个传输块，分别为TB1、TB2、TB3、TB4。图4a和图4b中的每个TB都对应一种传输状态，例如TB1为新传的传输块，TB2为重传的传输块。
在本申请的一些实施例中，第一通信设备可以工作在覆盖增强模式B，或覆盖增强等级2，或覆盖增强等级3。当第一通信设备工作在覆盖增强模式B时，控制信息调度的最大传输块个数可以是4个。不限定的是，第一通信设备也可以工作在其他模式，例如可以工作在覆盖增强模式A，或覆盖增强等级0，或覆盖增强等级1。当第一通信设备工作在覆盖增强模式A时，控制信息调度的最大传输块个数可以是8个。
为了指示控制信息调度的传输块个数以及指示待传输的传输块类型，第二通信设备可以生成标识(flag)信息。标识信息用于指示一个控制信息能够用于多个传输块的调度，或者一个控制信息只能用于一个传输块的调度。其中，一个控制信息能够用于多个传输块的调度是指一个控制信息能够调度多个传输块，一个控制信息只能用于一个传输块的调度是指一个传输块不能调度多个传输块，而是用于单个传输块的调度。
202、标识信息指示一个控制信息能够用于多个传输块的调度时，第二通信设备向第一通信设备发送标识信息和传输块分配信息，其中传输块分配信息指示了控制信息调度的传输块个数N和每个传输块对应的比特状态。
在本申请实施例中，标识信息指示一个控制信息能够用于多个传输块的调度时，该标识信息还指示了第二通信设备发送传输块分配信息，该传输块分配信息也可以称为TB分配指示信息，或者TB调度指示信息。第二通信设备根据控制信息调度的传输块个数N和每个传输块对应的比特状态生成传输块分配信息。第二通信设备向第一通信设备发送标识信息和传输块分配信息。例如，传输块分配信息包括M个比特，M个比特为b 0,b 1,…,b (M-1)，通过M个比特的比特状态可以指示控制信息调度的传输块个数N和每个传输块对应的比特状态。
在本申请的一些实施例中，为了使第一通信设备能够获取到该第二通信设备确定的传输块个数，第二通信设备可以生成标识信息，将该标识信息发送给第一通信设备，从而使 得第一通信设备能够根据接收到的标识信息来获取到该第二通信设备确定的传输块个数。另外，第二通信设备发送的标识信息用于指示一个控制信息调度多个传输块时，该标识信息还可以指示第一通信设备接收第二通信设备发送的传输块分配信息。
需要说明的是，步骤202中第二通信设备向第一通信设备发送标识信息和传输块分配信息，该标识信息和传输块分配信息可以使用同一个信息来传输，或者标识信息和传输块分配信息分别使用不同的信息来传输，例如标识信息通过高层信令来传输，传输块分配信息通过控制信息来传输。
在本申请的一些实施例中，步骤202中的第二通信设备向第一通信设备发送标识信息包括：
第二通信设备向第一通信设备发送控制信息，控制信息包括标识信息。
或者，第二通信设备向第一通信设备发送高层信令，高层信令包括标识信息。
其中，第二通信设备生成标识信息之后，第二通信设备可以采用多种方式来发送该标识信息。例如第二通信设备可以采用高层信令，该高层信令可以包括标识信息，从而第一通信设备可以接收该高层信令，通过解析该高层信令可以得到第二通信设备生成的标识信息。例如该高层信令可包括：无线资源控制(radio resource control，RRC)信令。另外，第二通信设备可以采用物理层信令，该物理层信令可以包括标识信息，从而第一通信设备可以接收该物理层信令，通过解析该物理层信令可以得到第二通信设备生成的标识信息。例如该物理层信令可为：前述的控制信息，进一步的，该控制信息可以包括标识信息。
在本申请的一些实施例中，标识信息指示一个控制信息能够用于多个传输块的调度时，控制信息还包括传输块分配信息。
其中，传输块分配信息和标识信息都可以通过控制信息来传输，对于控制信息中的传输块分配信息和标识信息的位置关系，以及传输块分配信息和标识信息在控制信息中所占用的比特数，不做限定。通过控制信息来传输传输块分配信息和标识信息，使得第一通信设备通过接收控制信息就可以获取到传输块分配信息和标识信息，进而根据传输块分配信息和标识信息来完成数据传输。
203、第二通信设备根据每个传输块对应的比特状态，使用控制信息指示的至少一个传输块，向第一通信设备发送数据，至少一个传输块属于N个传输块。或者,
204、第二通信设备根据每个传输块对应的比特状态，使用控制信息指示的至少一个传输块，接收第一通信设备发送的数据，至少一个传输块属于N个传输块。

211、第一通信设备接收第二通信设备发送的标识信息。
在本申请的一些实施例中，为了使第一通信设备能够获取到该第二通信设备确定的传输块个数，第二通信设备可以生成标识信息，将该标识信息发送给第一通信设备，从而使得第一通信设备能够根据接收到的标识信息来获取到该第二通信设备确定的传输块个数。另外，第二通信设备发送的标识信息用于指示一个控制信息调度多个传输块时，该标识信息还可以指示第一通信设备接收第二通信设备发送的传输块分配信息。
在本申请的一些实施例中，步骤211第一通信设备接收第二通信设备发送的标识信息，可以包括如下步骤：
第一通信设备接收第二通信设备发送的高层信令，高层信令包括标识信息。
或者，第一通信设备接收第二通信设备发送的控制信息，控制信息包括标识信息。
其中，第二通信设备生成标识信息之后，第二通信设备可以采用多种方式来发送该标识信息。例如第二通信设备可以采用高层信令，该高层信令可以包括标识信息，从而第一通信设备可以接收该高层信令，通过解析该高层信令可以得到第二通信设备生成的标识信息。例如该高层信令可包括：RRC信令。另外，第二通信设备可以采用物理层信令，该物理层信令可以包括标识信息，从而第一通信设备可以接收该物理层信令，通过解析该物理层信令可以得到第二通信设备生成的标识信息。例如该物理层信令可为：前述的控制信息，进一步的，该控制信息可以包括标识信息。
212、标识信息指示一个控制信息能够用于多个传输块的调度时，第一通信设备获取第二通信设备发送的传输块分配信息，其中传输块分配信息指示了控制信息调度的传输块个数N和每个传输块对应的比特状态。
在本申请实施例中，标识信息指示一个控制信息能够用于多个传输块的调度时，该标识信息还指示了第二通信设备发送传输块分配信息，该传输块分配信息也可以称为TB分配指示信息，或者TB调度指示信息。第一通信设备接收第二通信设备发送的传输块分配信息，根据该传输块分配信息确定控制信息调度的传输块个数N和每个传输块对应的比特状态。例如，传输块分配信息包括M个比特，M个比特为b 0,b 1,…,b (M-1)，通过M个比特的比特状态可以指示控制信息调度的传输块个数N和每个传输块对应的比特状态。
213、第一通信设备根据标识信息和每个传输块对应的比特状态，使用控制信息指示的至少一个传输块，接收第二通信设备发送的数据，至少一个传输块属于N个传输块。

首先请参阅图3所示，为本申请实施例提供的网络设备和终端设备之间的一种交互流程示意图，本申请实施例提供的数据传输方法，主要包括如下步骤：
301、第二通信设备生成标识信息，标识信息用于指示一个控制信息能够用于多个传输块的调度，或者一个控制信息只能用于一个传输块的调度。
其中，步骤301与前述实施例中的步骤201类似，此处不再赘述。
302、标识信息指示一个控制信息只能用于一个传输块的调度时，第二通信设备向第一通信设备发送标识信息和混合自动重发请求(hybrid automatic retransmission request，HARQ)进程索引信息，其中HARQ进程索引信息指示了控制信息调度的一个传输块对应的HARQ进程索引。
在本申请实施例中，标识信息指示一个控制信息只能用于一个传输块的调度时，该标识信息还指示了第二通信设备发送HARQ进程索引信息。第二通信设备根据控制信息调度的一个传输块和一个传输块对应的HARQ进程索引生成HARQ进程索引信息，HARQ进程索引信息也可以称为HARQ进程索引指示信息，第二通信设备向第一通信设备发送标识信息和HARQ进程索引信息，例如，控制信息中可以有3个比特用于HARQ进程索引指示。
需要说明的是，步骤302中第二通信设备向第一通信设备发送标识信息和传输块分配信息，该标识信息和传输块分配信息可以使用同一个信息来传输，或者标识信息和传输块分配信息分别使用不同的信息来传输，例如标识信息通过高层信令来传输，传输块分配信息通过控制信息来传输。
在本申请的一些实施例中，标识信息指示一个控制信息只能用于调度一个传输块的调度时，控制信息包括HARQ进程索引信息。
其中，HARQ进程索引信息和标识信息都可以通过控制信息来传输，对于控制信息中的HARQ进程索引信息和标识信息的位置关系，以及HARQ进程索引信息和标识信息在控制信息中所占用的比特数，不做限定。通过控制信息来传输HARQ进程索引信息和标识信息，使得第一通信设备通过接收控制信息就可以获取到传输HARQ进程索引信息和标识信息，进而根据传输HARQ进程索引信息和标识信息来完成数据传输。
在本申请的一些实施例中，标识信息指示一个控制信息能够用于多个传输块的调度时，控制信息还包括传输块分配信息，或者标识信息指示一个控制信息只能用于调度一个传输块的调度时，控制信息还包括HARQ进程索引信息。
其中，控制信息至少具有两种不同的比特结构，例如控制信息为DCI，一个DCI指示多个TB的传输，DCI采用第一比特结构，UE按照第一比特结构解读DCI的比特信息。另外，一个DCI还可以只调度一个TB的传输，DCI采用第二比特结构，UE按照第二比特结构解读DCI的比特信息。后续实施例中对第一比特结构和第二比特结构做出详细的举例说明。
303、第二通信设备根据一个传输块对应的HARQ进程索引，向第一通信设备发送数据，或者，
304、第二通信设备根据一个传输块对应的HARQ进程索引，接收第一通信设备发送的数据。
在本申请实施例中，第二通信设备向第一通信设备传输块分配指示信息之后，第二通 信设备可以根据确定的一个传输块对应的HARQ进程索引，和第一通信设备进行数据传输。例如第二通信设备根据标识信息确定当前数据传输可以使用的传输块个数，第二通信设备根据确定的一个传输块对应的HARQ进程索引确定当前数据传输可以使用的HARQ进程索引。同样的，第一通信设备根据标识信息确定当前数据传输可以使用的传输块个数，第一通信设备根据确定的一个传输块对应的HARQ进程索引确定当前数据传输可以使用的HARQ进程索引。进一步的，当第二通信设备向第一通信设备发送数据时，该第二通信设备还需要确定控制信息调度的所有传输块中每个传输块为新传的传输块，还是重传的传输块。
需要说明的是，步骤303和步骤304可根据应用场景确定执行哪个步骤，此处不做些限定。
311、第一通信设备接收第二通信设备发送的标识信息。
在本申请的一些实施例中，为了使第一通信设备能够获取到该第二通信设备确定的传输块个数，第二通信设备可以生成标识信息，将该标识信息发送给第一通信设备，从而使得第一通信设备能够根据接收到的标识信息来获取到该第二通信设备确定的传输块个数。另外，第二通信设备发送的标识信息用于指示一个控制信息只能用于一个传输块的调度时，该标识信息还可以指示第一通信设备接收第二通信设备发送的HARQ进程索引信息。
312、标识信息指示一个控制信息只能用于一个传输块的调度时，第一通信设备获取第二通信设备发送的混合自动重发请求HARQ进程索引信息，其中HARQ进程索引信息指示了控制信息调度的一个传输块对应的HARQ进程索引。
313、第一通信设备根据标识信息和一个传输块对应的HARQ进程索引，接收第二通信设备发送的数据。
314、第一通信设备根据标识信息和一个传输块对应的HARQ进程索引，向第二通信设备发送数据。
在本申请实施例中，第二通信设备向第一通信设备传输块分配指示信息之后，第二通信设备可以根据标识信息和确定的一个传输块对应的HARQ进程索引，和第一通信设备进行数据传输。例如第二通信设备根据标识信息确定当前数据传输可以使用的传输块个数，第二通信设备根据确定的一个传输块对应的HARQ进程索引确定当前数据传输可以使用的HARQ进程索引。同样的，第一通信设备根据标识信息确定当前数据传输可以使用的传输块个数，第一通信设备根据确定的一个传输块对应的HARQ进程索引确定当前数据传输可以使用的HARQ进程索引。进一步的，当第一通信设备向第二通信设备发送数据时，该第一通信设备还需要确定控制信息调度的所有传输块中每个传输块为新传的传输块，还是重传的传输块。
在本申请的一些实施例中，第二通信设备生成的传输块分配信息包括M个比特，M个比特为b 0,b 1,…,b (M-1)，并且b 0是M个比特中的最左侧的比特，b (M-1)是M个比特中的最右侧的比特；
M个比特中第j+1个比特为b j，b j＝1，且在M个比特中，位于b j左侧的比特的状态都为0，则控制信息调度了(K-j)个TB；或，
M个比特中第c+1个比特为b c，b c＝0，且在M个比特中，位于b c左侧的比特的状态都为0，则控制信息调度了(K-c)个TB；
其中，M是正整数，K是正整数，所述K小于所述M；
j是整数，且j等于如下取值中的任意一个：0,1,2,…(M-1)；
c是整数，且c等于如下取值中的任意一个：0,1,2,…(M-1)。
其中，传输块分配信息包括M个比特，M的取值大小可以具体场景来确定，例如根据第一通信设备和第二通信设备的传输能力以及所配置的传输模式来确定。例如M个比特为b 0,b 1,…,b (M-1)，并且b 0是M个比特中的最左侧的比特，b (M-1)是M个比特中的最右侧的比特，即通信设备在b 0,b 1,…,b (M-1)中从左至右依次获取各个比特的取值。M个比特中第j+1个比特为b j，b j＝1，且在M个比特中，位于b j左侧的比特的状态都为0，则控制信息调度了(K-j)个TB，从第一个非0的比特决定了控制信息调度的TB个数，K可以是预先配置的正整数，例如K可以表示一个控制信息能够调度的最大TB个数。另外，在M个比特中第c+1个比特为b c，b c＝0，且在M个比特中，位于b c左侧的比特的状态都为0，连续取值都为0的比特决定了控制信息调度的TB个数，例如控制信息调度了(K-c)个TB。
在本申请的一些实施例中，M个比特中第j+1个比特为b j，b j＝1，且在M个比特中，位于b j左侧的比特的状态都为0，则控制信息调度了(K-j)个TB，控制信息调度的(K-j)个TB的状态可以通过b j+1,…,b (M-1)的比特状态来确定。
需要说明的是，上述实施例中以左边第一个为1的比特所在的比特位指示了控制信息调度的TB个数为例阐述本申请实施例的方法。实际上，对上述实施例的比特位置或者比特状态做一些变换或者替换，仍属于本申请实施例的保护范围。例如，以b 0,b 1,…,b (M-1)中右边第一个为1的比特所在的比特位指示了控制信息调度的TB个数。例如，以b 0,b 1,…,b (M-1)中左边第一个为0的比特所在的比特位指示了控制信息调度的TB个数。例如，以b 0,b 1,…,b (M-1)中右边第一个为0的比特所在的比特位指示了控制信息调度的TB个数。
在本申请的一些实施例中，b j右侧的(K-j)个比特中的每个比特关联一个TB。
其中，对于b j右侧的(K-j)个比特中的每个比特的取值都可以用于确定一个TB的状态，通过b j右侧的(K-j)个比特中的每个比特可以确定出每个比特所关联的TB的状态。
进一步的，在本申请的一些实施例中，b j右侧的(K-j)个比特中的每个比特关联一个TB，包括：b j右侧的(K-j)个比特中的第p个比特关联控制信息指示的第p个TB，p是整数，且p等于如下取值中的任意一个：1,2,…(K-j)。
例如，b j右侧的(K-j)个比特中的第1个比特关联控制信息指示的第1个TB，b j右侧的(K-j)个比特中的第2个比特关联控制信息指示的第2个TB，因此通过b j右侧的(K-j)个比特中的每个比特可以确定出每个比特所关联的TB的状态。
在本申请的一些实施例中，b j右侧的(K-j)个比特中的每个比特关联一个TB，包括：所述b j右侧的(K-j)个比特关联的(K-j)个TB的HARQ进程索引是连续的。进一步的，当b j右侧的(K-j)个比特关联的(K-j)个TB的HARQ进程索引是连续时，所述(K-j)个TB中的第一个TB的HARQ进程索引固定为0。通过(K-j)个TB的HARQ进程索引是连续的可以快速的确定出控制信息指示的所有TB的HARQ进程索引的取值。
在本申请的一些实施例中，b j右侧的(K-j)个比特中的第p个比特的比特状态是第p个TB对应的比特状态。
其中，控制信息指示的第p个TB对应的比特状态可以是b j右侧的(K-j)个比特中的第 p个比特的比特状态，因此通过b j右侧的(K-j)个比特的比特状态可以确定出控制信息指示的TB对应的比特状态。
在本申请的一些实施例中，M、K的取值可以满足如下关系：M＝9,K＝8；和/或，M＝5,K＝4。具体可以根据场景来配置M和K的取值，例如M＝K+1。另外本申请实施例中，c＝6或7；和/或，c＝2或3。详见后续实施例中对M、K、c的取值的举例说明。

标识信息的X个比特的比特状态中有一种比特状态指示了：控制信息能够用于多个传输块的调度，且控制信息包括所述传输块分配信息，N个传输块TB中的第i个TB为TB i，若TB i对应的比特状态为0，则TB i为新传TB，若TB i对应的比特状态为1，则TB i是重传TB；和/或，
标识信息的X个比特的比特状态中有一种比特状态指示了：控制信息能够用于多个传输块的调度，且控制信息包括所述传输块分配信息，N个TB中的第i个TB为TB i，若TB i对应的比特状态为0，则TB i为新传TB，若TB i对应的比特状态为1，则第一通信设备不传输TB i或者忽略TB i；和/或，
标识信息的X个比特的比特状态中有一种比特状态指示了：控制信息能够用于多个传输块的调度，且控制信息包括所述传输块分配信息，N个TB中的第i个TB为TB i，若TB i对应的比特状态为1，则TB i为重传TB，若TB i对应的比特状态为0，则第一通信设备不传输TB i或者忽略TB i；和/或，

其中，N是正整数，i是整数，且i等于如下取值中的任意一个：1,2,…,N，或者0,1,…,(N-1)。
其中，标识信息的X个比特的比特状态中有一种比特状态指示了第一功能，即一个控制信息能够用于多个传输块的调度，若第二通信设备指示某个TB的比特状态为0，则该TB为新传TB，则第一通信设备传输该新传TB。若第二通信设备指示某个TB的比特状态为1，则该TB是重传TB，则第一通信设备传输该重传TB。可选地，控制信息采用第一比特结构，第一通信设备按照第一比特结构解读控制信息的比特信息。不限定的是，也可以根据比特状态为1确定TB为新传，或者根据比特状态为0确定TB为重传。
标识信息的X个比特的比特状态中的另一种比特状态指示了第二功能，即一个控制信息指示多个TB的传输。若第二通信设备指示某个TB的比特状态为0，则该TB为新传TB，则第一通信设备传输该新传TB。若第二通信设备指示某个TB的比特状态为1，则指示第一通信设备不传输该TB或者忽略第二通信设备指示的该TB。可选地，该TB可以是重传TB和/或没有调度的TB。可选地，控制信息采用第一比特结构，第一通信设备按照第一比特结构解读控制信息的比特信息。可以理解的是，本申请实施例中，第一通信设备不传输TB i或者忽略TB i可以具体场景来配置第一通信设备采用不传输的方式或者忽略的方式。
标识信息的X个比特的比特状态中的另一种比特状态指示了第三功能，即一个控制信息指示多个TB的传输。若第二通信设备指示某个TB的比特状态为1，则该TB为重传TB，则第一通信设备传输该重传TB。若第二通信设备指示某个TB的比特状态为0，则指示第一 通信设备不传输该TB或者忽略第二通信设备指示的该TB。可选地，该TB可以是新传TB和/或没有调度的TB。可选地，控制信息采用第一比特结构，第一通信设备按照第一比特结构解读控制信息的比特信息。
标识信息的X个比特的比特状态中的另一种比特状态指示了第四功能，即一个控制信息只能够用于一个传输块的调度。可选地，控制信息采用第二比特结构，第一通信设备按照第二比特结构解读控制信息的比特信息。
在本申请的一些实施例中，第二通信设备根据每个传输块对应的比特状态，使用控制信息指示的至少一个传输块，向第一通信设备发送数据,或者接收第一通信设备发送的数据，包括：
第二通信设备根据标识信息的X个比特的比特状态以及每个传输块对应的比特状态，使用控制信息指示的至少一个传输块，向第一通信设备发送数据,或者接收第一通信设备发送的数据。
其中，前述对标识信息的X个比特的比特状态所指示的不同功能做了举例说明，基于标识信息的具体限定，第二通信设备需要使用标识信息的X个比特的比特状态以及每个传输块对应的比特状态，使用控制信息指示的至少一个传输块进行数据收发。
进一步的，在本申请的一些实施例中，标识信息的比特个数X＝2；和/或，
所述N的取值为1,2,……,8；或者，
所述N的取值为2,……,8；或者，
所述N的取值为1,2,3,4；或者，

其中，若X的取值为2时，标识信息具有4种比特状态：00、01、10、11，例如，标识信息包括2个比特，这2个比特指示前述的第一功能、第二功能、第三功能，第四功能中的一种或者多种。具体可以根据场景来配置X的取值。
另外，本申请实施例中控制信息指示的TB块个数为N个，N的最大值可以为8，该N的取值可以是1,2,……,8中的任意一个值，例如N的取值1，或者3，或者4，或者5，或者6，或者7等。又如N的取值可以是2,……,8中的任意一个值。又如，N的最大值可以为4，该N的取值可以是1,2,3,4中的任意一个值，又如N的取值可以是2,3,4中的任意一个值，具体可以应用场景来确定控制信息指示的TB块个数。
通过前述的举例说明可知，在本申请实施例中，为了使第一通信设备能够获取到该第二通信设备确定的传输块个数，第二通信设备可以生成一个标识信息，将该标识信息发送给第一通信设备，从而使得第一通信设备能够根据接收到的标识信息来获取到该第二通信设备确定的传输块个数。为了节省控制信息的指示开销，本申请实施例中第二通信设备所生成的标识信息可以用于指示一个控制信息能够用于多个传输块的调度，或者一个控制信息只能用于一个传输块的调度，根据标识信息指示的传输块个数为多个时第二通信设备进一步发送传输块分配信息，或者根据标识信息指示的传输块个数为一个时第二通信设备进一步发送HARQ进程索引信息。本申请实施例中可以优化控制信息的比特开销，提升控制信息的传输性能。
为便于更好的理解和实施本申请实施例的上述方案，下面举例相应的应用场景来进行 具体说明。
本申请实施例中，第一通信设备发送标识信息给第二通信设备。第一通信设备可以是基站，或具有发送能力的设备。第二通信设备可以是用户设备，或具有接收能力的设备，或者是基站。以第一通信设备为UE，第二通信设备为基站进行示例说明，前述的控制信息具体为DCI，本申请实施例中DCI调度多个传输块时，可以降低DCI指示的开销，提高资源效率。例如，第一通信设备通过下行控制信息发送标识信息给第二通信设备。即所述下行控制信息中包含所述标识信息。或者，第一通信设备通过无线资源控制信令或者媒体接入控制信令中发送标识信息给第二通信设备。即所述无线资源控制信令或者媒体接入控制信令中包含所述标识信息。
需要说明的是，本申请实施例中传输是发送或接收。若通信的一端将传输实施为发送，则通信的对端则实施为接收。
如图5所示，为本申请实施例提供的传输块分配信息包括的9个比特指示的比特状态示意图。假设一个DCI可以调度的TB数最多为K个TB，那么可以用K+1个比特指示DCI调度的TB数及DCI调度的TB中各个TB对应的比特状态。b 0至b K共K+1个比特指示了DCI调度的TB个数N及N个TB中各个TB对应的比特状态。其中N是正整数。例如，N取值2至K或者N取值1至K。
如图5所示，K＝8,b 0至b 8共9个比特指示了DCI调度的TB个数N及N个TB中各个TB对应的比特状态。其中N是正整数。例如，N取值2至8或者N取值1至8。
b 0至b 8这9个比特中，从左至右(b 0是最左边的比特，b 8是最右边的比特)，左边第一个为1的比特所在的比特位指示了DCI调度的TB个数。
例如，b 0＝1，则说明DCI调度了8个TB。此时，b 1至b 8共8个比特指示了DCI调度的8个TB中各个TB对应的比特状态。
例如，b 1＝1，且b 1左侧的比特的状态都为0，则说明DCI调度了7个TB。此时，b 2至b 8共7个比特指示了DCI调度的7个TB中各个TB对应的比特状态。
例如，b 2＝1，且b 2左侧的比特的状态都为0，则说明DCI调度了6个TB。此时，b 3至b 8共6个比特指示了DCI调度的6个TB中各个TB对应的比特状态。

例如，b 6＝1，且b 6左侧的比特的状态都为0，则说明DCI调度了2个TB。此时，b 7至b 8共2个比特指示了DCI调度的2个TB中各个TB对应的比特状态。
例如，b 7＝1，且b 7左侧的比特的状态都为0，则说明DCI调度了1个TB。此时，b 8比特指示了DCI调度的1个TB对应的比特状态。

需要说明的是，以上是以左边第一个为1的比特所在的比特位指示了DCI调度的TB个数为例阐述本申请实施例的方法。实际上，对上述实施的比特位置或者比特状态做一些变换或者替换，仍属于本申请实施例的保护范围。例如，以b 0至b 8中右边第一个为1的比特所在的比特位指示了DCI调度的TB个数。例如，以b 0至b 8中左边第一个为0的比特所在的比特位指示了DCI调度的TB个数。例如，以b 0至b 8中右边第一个为0的比特所在的比特位指示了DCI调度的TB个数。

例如，b 0＝1，则说明DCI调度了4个TB。此时，b 1至b 4共4个比特指示了DCI调度的4个TB中各个TB对应的比特状态。例如，b 1＝1，且b 1左侧的比特的状态都为0，则说明DCI调度了3个TB。此时，b 2至b 4共3个比特指示了DCI调度的3个TB中各个TB对应的比特状态。例如，b 2＝1，且b 2左侧的比特的状态都为0，则说明DCI调度了2个TB。此时，b 3至b 4共2个比特指示了DCI调度的2个TB中各个TB对应的比特状态。例如，b 3＝1，且b 3左侧的比特的状态都为0，则说明 DCI调度了1个TB。此时，b 4指示了DCI调度的1个TB对应的比特状态。

图6为本申请实施例提供的下行控制信息承载标识信息的示意图，标识信息可以是下行控制信息中的标识信息。该标识信息指示了下行控制信息是用于多TB的调度。当标识信息指示了下行控制信息是用于多TB的调度时，该标识信息还可以进一步指示了UE对下行控制信息调度的多个TB的处理。进一步地，该标识信息还可以指示行控制信息是用于单TB的调度。
例如，标识信息包括2个比特，这2个比特指示了第一功能、第二功能、第三功能、第四功能中的一种或者多种。
第一功能:一个DCI指示多个TB的传输。若基站指示某个TB的比特状态为0，则该TB为新传TB，则UE传输该新传TB。若基站指示某个TB的比特状态为1，则该TB是重传TB，则UE传输该重传TB。可选地，DCI采用第一比特结构，UE按照第一比特结构解读DCI的比特信息。
第二功能:一个DCI指示多个TB的传输。若基站指示某个TB的比特状态为0，则该TB为新传TB，则UE传输该新传TB。若基站指示某个TB的比特状态为1，则指示UE不传输该TB或者忽略基站指示的该TB。可选地，该TB可以是重传TB和/或没有调度的TB。可选地，DCI采用第一比特结构，UE按照第一比特结构解读DCI的比特信息。
第三功能:一个DCI指示多个TB的传输。若基站指示某个TB的比特状态为1，则该TB为重传TB，则UE传输该重传TB。若基站指示某个TB的比特状态为0，则指示UE不传输该TB或者忽略基站指示的该TB。可选地，该TB可以是新传TB和/或没有调度的TB。可选地，DCI采用第一比特结构，UE按照第一比特结构解读DCI的比特信息。
第四功能:一个DCI只调度一个TB的传输。可选地，DCI采用第二比特结构，UE按照第二比特结构解读DCI的比特信息。
如下表10所示，用2个比特例示了一种DCI中的标识信息指示了第一功能、第二功能、第三功能，第四功能以及DCI的比特结构。可选地，比特结构可以根据功能隐含地得出。例如，第一功能、第二功能和第三功能对应的都是第一比特结构。例如，第四功能对应的是第二比特结构。因此，基站指示了DCI的功能，就相当于指示了DCI比特结构。
表10：
比特状态 DCI功能 DCI比特结构
00 第一功能 第一比特结构
01 第二功能 第一比特结构
10 第三功能 第一比特结构
11 第四功能 第二比特结构

表11：
比特状态 DCI功能 DCI比特结构
00 第四功能 第二比特结构
01 第一功能 第一比特结构
10 第二功能 第一比特结构
11 第三功能 第一比特结构
在第一比特结构的下行控制信息中，DCI包括标识信息，DCI还包括TB分配指示信息或TB调度指示信息。例如，TB分配指示信息或TB调度指示信息包括8至10个比特。该DCI可以同时调度多个TB块。图7a为本申请实施例提供的标识信息指示的一种比特结构的示意图，示意了一种第一比特结构的下行控制信息，TB分配指示信息或TB调度指示信息包括9个比特，即对应前述的b 0至b 8比特。
图7b为本申请实施例提供的标识信息指示的另一种比特结构的示意图，在第二比特结构的下行控制信息中，DCI包括标识信息，DCI只调度一个TB块，且DCI还包括对该TB的HARQ process索引指示的信息。图7b中，示意了一种第二比特结构的下行控制信息，用3个比特指示DCI调度的单个TB的HARQ process索引。
图8a为本申请实施例提供的标识信息指示的一种功能示意图，标识信息为00，指示了第四功能。因此DCI调度了1个TB块。且DCI指示了该TB的HARQ索引为3。该DCI中还用5个比特指示了调制编码方式modulation coding scheme，MCS)。
图8b为本申请实施例提供的标识信息指示的另一种功能示意图，标识信息为01，指示了第一功能，且b0＝1。因此DCI指示了8个TB块。b1至b8按照比特位图(bitmap)方式指示8个TB中每个TB对应的比特的比特状态。b1至b8中的某个比特状态为0，表示该比特对应的TB为新传。b1至b8中的某个比特状态为1，表示该比特对应的TB为重传。如图8b所示，TB1,TB4，TB6,TB8为新传TB，TB2,TB3,TB5,TB7为重传TB。
图8c为本申请实施例提供的标识信息指示的另一种功能示意图，标识信息为10，指示了第二功能，且b0＝1。因此DCI指示了8个TB块。b1至b8按照bitmap方式指示8个TB块中每个TB对应的比特的比特状态。b1至b8中的某个比特状态为0，表示该比特对应的TB为新传。b1至b8中的某个比特状态为1，表示UE不传输或者忽略该比特对应的TB。如图8c所示，UE只对TB1,TB4,TB6，TB8进行新传传输，UE不传输或者忽略TB2,TB3,TB5,TB7。
图8d为本申请实施例提供的标识信息指示的另一种功能示意图，标识信息为11，指示了第三功能，且b0＝1。因此DCI指示了8个TB块。b1至b8按照bitmap方式指示8个TB块中每个TB对应的比特的比特状态。b1至b8中的某个比特状态为1，表示该比特对应的TB为重传。b1至b8中的某个比特状态为0，表示UE不传输或者忽略该比特对应的TB。如图8d所示，UE只对TB2,TB3,TB5，TB7进行重传传输，UE不传输或者忽略TB1,TB4,TB6,TB8。
下述给出了当一个DCI可以调度最多两个TB块时的指示方法。如下表12所示，用3比特指示DCI调度了一个TB还是2个TB，并且指示了调度的TB是新传还是重传。
第一通信设备生成标识信息，标识信息为3个比特，标识信息的不同比特状态关联不同的TB指示。
表12：
比特状态 TB指示
000 TB0,新传
001 TB1,新传
010 TB0,重传
011 TB1,重传
100 TB0新传；TB1新传；
101 TB0新传；TB1重传；
110 TB0重传；TB1新传；
111 TB0重传；TB1重传；
图9为本申请实施例提供的DCI使用3比特的指示方式示意图，当一个DCI可以调度最多两个TB块时，DCI中的一个比特指示该DCI是用于1个TB的调度还是用于2个TB的调度。
当DCI中的一个比特指示该DCI是用于1个TB的调度时，DCI中有一个比特指示传输的TB的HARQ process number，DCI中一个比特指示新数据指示(new data indicator，NDI)。新数据指示可以指示TB是初传还是重传。
当DCI中的一个比特指示该DCI是用于2个TB的调度时，DCI中有2个比特按照位图的方式指示传输的TB及指示TB是初传还是重传。
在本申请实施例中，DCI能够用很少的比特支持多TB调度，从而提高调度的灵活性和提高资源效率。
