Description

通信方法和通信装置 技术领域
本申请涉及通信领域，更为具体的，涉及通信方法和通信装置，尤其是短距离通信方法和装置。
背景技术
发送端通信装置可以向接收端通信装置发送数据。接收端通信装置可以向发送端通信装置上报接收数据的情况。例如，发送端通信装置可以向接收端通信装置发送数据和校验码。接收端通信装置可以对校验码校验，以判断接收端装置是否成功接收数据。如果接收端通信装置可以成功接收数据，接收端通信装置可以向发送端通信装置发送确认(acknowledge，ACK)信号；如果接收端通信装置无法成功接收数据，接收端通信装置可以向发送端通信装置发送否认(negative acknowledgment，NACK)信号。发送端通信装置可以根据接收数据的情况，判断是否要向接收端通信装置重新发送数据。这一过程可以被称为自动重传过程。自动重传过程中的通信质量、通信效率始终被关注。
发明内容

发送所述数据包；
其中，所述至少一个第一码字是对至少一个第一编码块进行第一编码得到的，所述至少一个第一编码块中每个第一编码块包含第一信息块以及用于校验所述第一信息块的第一校验块，所述至少一个第二码字是对至少一个第二编码块进行至少一种第二编码得到的，所述至少一个第二编码块包含第二校验块，所述第二校验块用于校验所述至少一个第二编码块中的部分信息。
编码块可以指编码之前的比特数据。码字可以指编码后的比特数据。码长可以指码字的长度。编码块中的信息内容可以包括信息块和校验块。校验块可以指具有校验功能的比特数据。信息块可以不具有校验功能。
对于任意比特数量的信息，均可以通过分段和编码，得到包括多个码字的数据包，数据包可以包括码长不同的两个码字，不同码长的码字可以通过分别编码得到，每个码字的码长均满足预设码长。因此可以省去速率匹配，有利于节省数据传输的功耗。另外，每个码长相对较大的第一码字可以由第一校验块校验，将码长较小的多个第二编码块一起校验，有利于减少校验块在数据包中的开销占比，减少信令开销、提高通信效率。
结合第一方面，在第一方面的某些实现方式中，所述方法还包括：
获取至少一个第一信息块；
生成所述至少一个第一编码块中的至少一个第一校验块，所述第一校验块与所述第一校验块所在的第一编码块中的第一信息块对应。
待发送的信息的第一部分的比特数量可以相对较多，可以适于被划分至第一码字。该第一部分可以经校验编码，得到第一校验块。
结合第一方面，在第一方面的某些实现方式中，所述第二校验块是根据所述至少一个第二编码块中除所述第二校验块以外的至少部分信息生成。
待发送的信息的第二部分的比特数量不适于被划分至第一码字，则该第二部分可以被划分至多个第二码字，每个第二码字的码长可以相对较小，该第二部分校验可以经校验编码，得到第二校验块。
结合第一方面，在第一方面的某些实现方式中，所述至少一个第二编码块包含冗余信息，在所述至少一个第二编码块中，所述冗余信息位于所述第二校验块之前或者之后。
在有关待发送的信息和第二校验块的比特数量不足以填满多个第二编码块时，多个第二编码块可以包括冗余信息，以有利于使每个第二编码块可以满足预设编码块码长，每个第二码字的码长满足预设码长。冗余信息位于第二校验块之前，第二校验块可以校验多个第二编码块中除第二校验块以外的全部信息，第二校验块可以位于多个第二编码块的尾部，冗余信息位被第二校验块校验。冗余信息位于第二校验块之后，第二校验块可以校验多个第二编码块中除第二校验块以外的部分信息，冗余信息位不被第二校验块校验，误块率相对较低。
结合第一方面，在第一方面的某些实现方式中，在所述至少一个第二编码块中，所述第二校验块位于一个或多个连续的编码块中。
第二编码块的最小比特数量可以不受第二校验块的比特数量限制，有利于提高多个第二编码块的分段灵活性。
结合第一方面，在第一方面的某些实现方式中，所述数据包包含L个数据组，其中，所述L个数据组包含L 1个第一数据组和一个第二数据组，所述L 1个第一数据组中每个数据组包含n个所述第一码字，所述第二数据组包含所述至少一个第二码字，所述L 1、n大于或者等于1。
数据组包括的码字数量越大，则该数据组的误块率可能越大。数据组包括的码字数量越小，则该数据组的误块率可能越小。多个第一数据组中的第一码字的数量可以相同，有利于平衡多个第一数据组的误块率。结合第一方面，在第一方面的某些实现方式中，所述方法还包括：

例如，如图3所示，发送设备可以确定准备向接收设备发送的多个数据帧，多个数据帧可以包括数据帧0、数据帧1、数据帧2、数据帧3、数据帧4。发送设备可以向接收设备发送数据帧0、数据帧1、数据帧2、数据帧3、数据帧4。接收设备可以从发送设备接收数据帧0、数据帧1、数据帧2、数据帧3、数据帧4，并对数据帧0、数据帧1、数据帧2分别进行校验。在图3所示的示例中，接收设备可以从发送设备正确接收数据帧0、数据帧1，错误接收数据帧2。由于数据帧2未正确接收，接收设备可以不对接收到的数据帧3、数据帧4进行校验。接收设备可以向发送设备发送针对数据帧0、数据帧1的确认消息，以及针对数据帧2的否认消息。发送设备可以根据针对数据帧2的否认消息，重新向接收设备发送数据帧2、数据帧3、数据帧4。
由图3所示的示例可以看出，接收设备可能正确接收数据帧3、数据帧4。在接收设备正确接收数据帧3、数据帧4的情况下，发送设备可以向接收设备发送至少两次数据帧3、数据帧4，导致通信效率相对较低。

在图5所示的示例中，数据包可以包括H个第一码字和M个第二码字。应理解，数据包可以包括数量更多或更少的第一码字，也可以包括数据更多或更少的第二码字。例如，数据包可以仅包括1个第一码字和1个第二码字。
可选的，发送设备获取至少一个第一信息块；发送设备生成所述至少一个第一编码块中的至少一个第一校验块，所述第一校验块与所述第一校验块所在的第一编码块中的第一信息块对应。生成至少一个第一编码块的方式例如可以包括校验编码，如循环冗余校验(cyclic redundancy check，CRC)编码。
可选的，所述第一编码块的第一信息块至少根据所述第一编码块中的第一校验块校验解码(如CRC解码)得到。在一个示例中，接收设备可以将第一信息块和第一校验块输入校验多项式。如果校验多项式的结果为零，则第一信息块校验成功。
可选的，第一编码块可以包括冗余信息(有关冗余信息的说明在下文详细阐述)。所述第一编码块的第一信息块可以通过去冗余操作，并根据所述第一编码块中的第一校验块校验解码(如CRC解码)得到。
例如，冗余信息可以位于第一校验块之后。在将第一编码块中的冗余信息去除后，接收设备可以将第一信息块和第一校验块输入校验多项式。如果校验多项式的结果为零，则第一信息块校验成功。
又如，冗余信息可以位于第一校验块之前。接收设备可以将第一信息块、冗余信息和第一校验块输入校验多项式，如果校验多项式的结果为零，则第一信息块和冗余信息校验成功。之后接收设备可以将冗余信息去除，得到第一信息块。
下面结合图6，阐述对第一编码块进行第一编码的一个示例。
如图6所示，发送设备可以获取第一编码块，第一编码块可以包括第一信息块和第一校验块。第一编码块中的第一信息块和第一校验块相互对应。具体的，第一校验块可以用于校验对应的第一信息块，即第一校验块可以用于校验第一校验块所在的第一编码块中的第一信息块。发送设备可以根据第一信息块，生成对应的第一校验块。发送设备可以对第一编码块进行第一编码，得到第一码字。
接收设备对数据包中的第一码字执行第一解码，可以得到第一编码块，第一编码块可以包括第一信息块和第一校验块。接收设备可以根据第一校验块，校验第一校验块所在的第一编码块中的第一信息块是否正确，从而确定向发送设备反馈确认消息或否认消息。发送设备可以根据接收设备的反馈，确定是否要重传第一码字。
数据包可以包括多个第一码字。在生成多个第一码字之前，发送设备可以获取多个第一信息块。发送设备可以对多个第一信息块中的每个第一信息块执行校验编码，得到多个第一校验块，多个第一校验块与多个第一信息块一一对应。任一第一校验块可以与对应的 第一信息块级联。任一第一校验块可以位于对应的第一信息块之后。任一第一校验块可以和对应的第一信息块构成第一编码块。多个第一信息块和多个第一校验块可以构成多个第一编码块，从而发送设备可以获取多个第一编码块。其中，上一级第一编码块中的第一校验块可以与下一级第一编码块中的第一信息块级联。下一级第一编码块中的第一信息块可以位于上一级第一编码块中的第一校验块之后。参照图6所示的示例，发送设备可以对多个第一编码块中的每个第一编码块可以执行第一编码(多个第一编码块可以同步或先后执行第一编码)，进而得到多个第一码字。第一信息块的比特数量可以为K 1’，第一校验块的比特数量可以为K 1”。在一个示例中，第一编码块的比特数量可以为K 1，K 1≥K 1’+K 1”。对第一编码块进行第一编码，可以得到第一码字，第一码字的码长(或比特数量)可以为N 1。第一编码的码率可以为K 1/N 1。
结合图5、图6，数据包可以包括多个第一码字。在生成多个第一码字之前，发送设备可以获取多个第一编码块，多个第一编码块可以与多个第一码字一一对应。发送设备可以对每个第一编码块执行第一编码。在一个示例中，每个第一码字的码长可以相同，每个第一编码块的比特数量可以相同。每个第一编码的码率可以相同。多个第一编码块可以经过相同类型的编码，生成多个第一码字。在一个可能的示例中，第一编码例如可以属于极化码(Polar码、Polar Code等)编码。多个第一码字的解码过程可以参照多个第一编码块的编码过程，在此不再赘述。
可选的，所述第二校验块是根据所述至少一个第二编码块中除所述第二校验块以外的至少部分信息生成。生成至少一个第二编码块的方式例如可以包括校验编码，如CRC编码。可选的，在至少一个第二编码块包括多个第二编码块的情况下，生成至少一个第二编码块的方式还可以包括数据分段，从而形成多个第二编码块。可选的，生成至少一个第二编码块的方式还可以包括加冗余操作，即至少一个第二编码块可以包括冗余信息。
可选的，所述至少一个第二编码块中除所述第二校验块以外的至少部分信息是根据所述第二校验块校验解码(如CRC解码)得到。在一个示例中，接收设备可以将至少一个第二编码块输入校验多项式。如果校验多项式的结果为零，则第一信息块校验成功。
可选的，至少一个第二编码块可以包括冗余信息。所述至少一个第二编码块中除所述第二校验块以外的至少部分信息可以通过去冗余操作，并根据所述第二校验块校验解码得到。
例如，冗余信息可以位于第二校验块之后。在将至少一个第二编码块中的冗余信息去除后，接收设备可以将至少一个第二编码块中除冗余信息以外的信息输入校验多项式。如果校验多项式的结果为零，则至少一个第二编码块中除所述第二校验块、冗余信息以外的信息校验成功。
又如，冗余信息可以位于第一校验块之前。接收设备可以将至少一个第二编码块中除所述第二校验块以外的信息(包括冗余信息)输入校验多项式，如果校验多项式的结果为零，则至少一个第二编码块中除所述第二校验块以外的信息校验成功。之后接收设备可以将冗余信息去除，得到至少一个第二编码块中除所述第二校验块、冗余信息以外的信息。
下面结合图7，阐述对至少一个第二编码块进行至少一种第二编码的一个示例。在图7所示的示例中，数据包可以包括单个第二码字。
发送设备可以获取单个第二编码块，单个第二编码块可以包括第二信息块和第二校验 块。其中，单个第二编码块中的第二信息块和第二校验块相互对应。第二校验块可以用于校验对应的第二信息块。发送设备可以根据第二信息块，生成对应的第二校验块。发送设备可以对单个第二编码块进行第二编码，得到单个第二码字。
接收设备对数据包中的单个第二码字执行第二解码，可以得到第二编码块，第二编码块可以包括第二信息块和第二校验块。接收设备可以根据第二校验块，校验与第二校验块对应的第二信息块是否正确，从而确定向发送设备反馈确认消息或否认消息。发送设备可以根据接收设备的反馈，确定是否要重传单个第二码字。
可选的，单个第二码字包含冗余信息，在单个第二码字中，所述冗余信息位于第二校验块之前或者之后。冗余信息位于第二校验块之前，则第二校验块可以用于校验冗余信息。冗余信息位于第二校验块之后，则第二校验块可以不用于校验冗余信息，例如第二校验块可以与冗余信息无关。
冗余信息可以指，除去传输信息时所需最小限度信息外的其他信息，可称为冗余信息。在一个示例中，冗余信息的全部信息位例如可以取值0或1。冗余信息位于第二校验块之前，可以指冗余信息在单个第二编码块中的位置位于第二校验块之前。冗余信息位于第二校验块之后，可以指冗余信息在单个第二编码块中的位置位于第二校验块之后。
第二信息块的比特数量可以为K 2’，第二校验块的比特数量可以为K 2”。在一个示例中，第二编码块的比特数量可以为K 2，K 2≥K 2’+K 2”。例如，第二编码块可以包括冗余信息，冗余信息的比特数量可以为K 2”’，K 2＝K 2’+K 2”+K 2”’。对第二编码块进行第二编码，可以得到第二码字，第二码字的码长(或比特数量)可以为N 2。第二编码的码率可以为K 2/N 2。
在数据包包括单个第二码字的情况下，单个第二码字的码长可以小于第一码字的码长。第二编码块的比特数量和第一编码块的比特数量可以不同。第一编码的码率和第二编码的码率可以相同或不同。
例如，第一编码块的比特数量为1000，第一码字的码长为1024，第一编码的码率可以为1000/1024。第二编码块的比特数量为400，第二码字的码长为512，第二编码的码率可以为400/512。
又如，第一编码块的比特数量为1000，第一码字的码长为1024，第一编码的码率可以为1000/1024。第二编码块的比特数量为500，第二码字的码长为512，第二编码的码率可以为500/512。
又如，第一编码块的比特数量为1000，第一码字的码长为1024，第一编码的码率可以为1000/1024。第二编码块的比特数量为60，第二码字的码长为128，第二编码的码率可以为60/128。
单个第二码字的解码过程可以参照单个第二编码块的编码过程，在此不再赘述。
下面结合图8、图9，阐述对至少一个第二编码块进行至少一种第二编码的另一个示例。在图8、图9所示的示例中，数据包可以包括多个第二码字。
发送设备可以获取多个第二编码块。如图8、图9所示，多个第二编码块可以包括第二编码块1、第二编码块2、……、第二编码块M-1、第二编码块M。多个第二编码块可以包括第二校验块。可选的，在所述至少一个第二编码块中，所述第二校验块位于一个或多个连续的编码块中。也就是说，第二校验块可以位于多个第二编码块中的一个编码块， 或者，第二校验块可以位于多个第二编码块中的多个连续的编码块。如图8、图9所示，第二校验块可以由填充有斜线的图案示出。多个连续的编码块可以指，多个编码块在位置上连续。例如多个连续的编码块包括K个编码块，分别为编码块1，编码块2，……，编码块K-1，编码块K，其中，编码块k在位置上与编码块k-1相邻，且编码块k在位置上与k+1相邻，k∈(1,K)。两个相邻的编码块可以级联。例如编码块k的头部可以与编码块k-1的尾部级联，编码块k的尾部可以与编码块k+1的头部级联。
在图8所示的示例中，第二校验块的第一部分可以属于第二编码块M-1，第二校验块的第二部分可以属于第二编码块M。第二编码块M-1和第二编码块M可以相邻。假设第二编码块M-1的比特数量可以为K 2,M-1，第二编码块M的比特数量可以为K 2,M，第二校验块的比特数量可以为K 2”，K 2,M≤K 2”≤K 2,M-1+K 2,M。
在图9所示的示例中，第二校验块可以属于第二编码块M。假设第二编码块M的比特数量可以为K 2,M，第二校验块的比特数量可以为K 2”，K 2”≤K 2,M。
第二校验块可以用于校验多个第二编码块中除第二校验块以外的至少部分信息。
可选的，所述至少一个第二编码块包含冗余信息，在所述至少一个第二编码块中，所述冗余信息位于所述第二校验块之前或者之后。
在图8所示的示例中，第二校验块可以用于校验多个第二编码块中除第二校验块以外的全部信息。也就是说，多个第二编码块中除第二校验块以外的全部信息可以位于第二校验块之间。第二校验块可以由发送设备根据多个第二编码块中除第二校验块以外的全部信息生成。相应地，通过对第二校验块校验，接收设备可以确定多个第二编码块中除第二校验块以外的全部信息是否正确接收，从而确定向发送设备反馈确认消息或否认消息。发送设备可以根据接收设备的反馈，确定是否要重传多个第二码字。
可选的，多个第二编码块中除第二校验块以外的全部信息可以包括冗余信息，冗余信息可以位于第二校验块之前。如图8所示，冗余信息可以由填充有菱形的图案示出。也就是说，在多个第二编码块还包括冗余信息的情况下，第二校验块可以用于校验冗余信息。冗余信息位于第二校验块之前，可以指冗余信息在多个第二编码块中的位置位于第二校验块之前。
在图9所示的示例中，第二校验块可以用于校验多个第二编码块中除第二校验块以外的部分信息。也就是说，多个第二编码块中除第二校验块以外的全部信息可以包括第一部分信息和第二部分信息，第一部分信息可以位于第二校验块之前，第二部分信息可以位于第二校验块之后。第二校验块可以用于校验该第一部分信息，且不用于校验该第二部分信息。第二校验块可以由发送设备根据该第一部分信息生成。第二校验块的生成可以不与该第二部分信息相关。相应地，通过对第二校验块校验，接收设备可以确定该第一部分信息是否正确接收，从而确定向发送设备反馈确认消息或否认消息。发送设备可以根据接收设备的反馈，确定是否要重传多个第二码字。
在一个可能的示例中，该第二部分信息可以是冗余信息。无论冗余信息是否正确接收，均不影响信息发送设备和接收设备之间的正常通信。
可选的，多个第二编码块中除第二校验块以外的全部信息可以包括冗余信息，冗余信息可以位于第二校验块之后。如图9所示，冗余信息可以由填充有菱形的图案示出。也就是说，第二校验块可以不用于校验位于所述第二校验块之后的冗余信息。冗余信息位于第 二校验块之后，可以指冗余信息在多个第二编码块中的位置位于第二校验块之后。
发送设备可以对多个第二编码块进行至少一种第二编码，得到多个第二码字。相应地，接收设备对数据包中的多个第二码字执行至少一种第二解码，可以得到多个第二编码块。可选的，所述至少一个第二码字包括编码码率不同的至少两个第二码字。下面通过一些示例，阐述多个第二编码块的编码过程。
假设多个第二编码块可以包括第二编码块i，第二编码块j。第二编码块i的比特数量可以为K 2,i，第二编码块j的比特数量可以为K 2,j。发送设备对多个第二编码块进行至少一种第二编码，可以得到多个第二码字。多个第二码字可以与多个第二编码块一一对应。多个第二码字可以包括第二码字i，第二码字j。第二码字i可以与第二编码块i对应，即第二码字i可以由第二编码块i经过第二编码得到。第二码字j可以与第二编码块j对应，即第二码字j可以由第二编码块j经过第二编码得到。第二码字i的码长可以为N 2,i，第二码字j的码长可以为N 2,j。
在一个示例中，第二编码块i的比特数量K 2,i可以与第二编码块j的比特数量K 2,j相同。对第二编码块i，第二编码块j进行相同类型的第二编码，则第二码字i的码长N 2,i可以与第二码字j的码长N 2,j相同。该相同类型的第二编码的码率可以为K 2,i/N 2,i＝K 2,j/N 2,j。
在另一个示例中，第二编码块i的比特数量K 2,i可以与第二编码块j的比特数量K 2,j相同。对第二编码块i进行第二编码i，对第二编码块j进行第二编码j，第二编码i、第二编码j属于不同类型的编码。则第二码字i的码长N 2,i可以与第二码字j的码长N 2,j不同。第二编码i的码率可以为K 2,i/N 2,i，第二编码j的码率可以为K 2,j/N 2,j，K 2,i/N 2,i≠K 2,j/N 2,j。
在又一个示例中，第二编码块i的比特数量K 2,i可以与第二编码块j的比特数量K 2,j不同。对第二编码块i进行第二编码i，对第二编码块j进行第二编码j，第二编码i、第二编码j属于不同类型的编码。则第二码字i的码长N 2,i与第二码字j的码长N 2,j可以相同或不同。第二编码i的码率可以为K 2,i/N 2,i，第二编码j的码率可以为K 2,j/N 2,j，K 2,i/N 2,i与K 2,j/N 2,j可以相同或不同。
多个第二码字的解码过程可以参照多个第二编码块的编码过程，在此不再赘述。
可选的，所述至少一个第一码字的码长相同。
结合图4至图9，数据包可以包括H个码长为N 1的第一码字以及M个第二码字，M个第二码字的码长可以分别为N 2,1、N 2,2、……、N 2,M-1、N 2,M。
在一个示例中，N 1>N 2,1+N 2,2+……+N 2,M-1+N 2,M。例如，第一码字的码长N 1可以为1024，M个第二码字可以包括码长为64的1个第二码字和码长为128的1个第二码字。
在另一个示例中，N 1＝N 2,1+N 2,2+……+N 2,M-1+N 2,M。例如，第一码字的码长N 1可以为1024，M个第二码字可以包括码长为512的1个第二码字和码长为256的2个第二码字。
在又一个示例中，N 1<N 2,1+N 2,2+……+N 2,M-1+N 2,M。例如，第一码字的码长N 1可以为1024，M个第二码字可以包括码长为512的2个第二码字和码长为256的1个第二码字。
可选的，所述至少一个第二码字的码长之和小于所述第一码字的码长。
可选的，多个第二码字可以按照码长大小顺序排列。例如，N 2,1>N 2,2>……>N 2,M-1>N 2,M，N 2,i可以为第二码字i的码长，i∈[1,M]。
可选的，发送设备可以对所述数据包中的多个码字进行分组。相应地，接收设备可以根据所述数据包的分组情况，向发送设备发送反馈消息。发送设备可以根据接收设备发送的反馈消息，确定是否重新发送所述数据包中的码字。数据包的分组数量可以由高层信令配置。高层信令例如可以是广播信息、***消息、高层配置信令、介质访问控制层信令等等中的一个或者多个。
下面阐述数据包的几种分组方案。

在一种可能的分组方案中，数据包中的H个第一码字可以被划分为L 1个第一数据组，M个第二码字可以被划分为第二数据组。
可选的，所述n满足n＝ceil(H/(L-1))，其中H为所述至少一个第一码字的总数量。
在一个可能的示例中，mod(H,(L-1))＝0，则数据包可以被划分为L 1个第一数据组和1个第二数据组，L 1＝L-1。该L 1个第一数据组中的每个第一数据组包括n个第一码字，n＝H/(L-1)，该1个第二数据组可以包括M个第二码字。
例如，H＝1，M＝2，L＝2，则数据包可以被划分为1个第一数据组和1个第二数据组，该1个第一数据组可以包括1个第一码字，该1个第二数据组可以包括2个第二码字。
又如，H＝4，M＝2，L＝3，则数据包可以被划分为2个第一数据组和1个第二数据组，该2个第一数据组中的每个第一数据组可以包括2个第一码字，该1个第二数据组可以包括2个第二码字。

L 1个第一数据组中的目标第一数据组可以包括n个第一码字。接收设备对该n个第一码字解码可以得到n个第一编码块。如果n个第一编码块的n个第一校验块均校验成功，则接收设备可以针对目标第一数据组，向发送设备发送第一反馈信息，该第一反馈信息可以用于指示接收设备正确接收目标第一数据组中的数据。如果n个第一编码块的n个第一校验块中存在校验失败的校验块，则接收设备可以针对目标第一数据组，向发送设备发送第二反馈信息，该第二反馈信息可以用于指示接收设备错误接收目标第一数据组中的数据。相应地，发送设备可以向接收设备重新发送目标第一数据组中的至少部分数据。
L个数据组中的第二数据组可以包括M个第二码字。接收设备对该M个第二码字解码可以得到M个第二编码块。如果M个第二编码块的第二校验块校验成功，则接收设备可以针对第二数据组，向发送设备发送第三反馈信息，该第三反馈信息可以用于指示接收设备正确接收第二数据组中的数据。如果M个第二编码块的第二校验块校验失败，则接收设备可以针对第二数据组，向发送设备发送第四反馈信息，该第四反馈信息可以用于指示接收设备错误接收第二数据组中的数据。相应地，发送设备可以向接收设备重新发送第二数据组中的至少部分数据。
L 2个第三数据组中的目标第三数据组可以包括p个第一码字。接收设备对该p个第一码字解码可以得到p个第一编码块。如果p个第一编码块的p个第一校验块均校验成功，则接收设备可以针对目标第三数据组，向发送设备发送第五反馈信息，该第五反馈信息可以用于指示接收设备正确接收目标第三数据组中的数据。如果p个第一编码块的p个第一校验块中存在校验失败的校验块，则接收设备可以针对目标第三数据组，向发送设备发送第六反馈信息，该第六反馈信息可以用于指示接收设备错误接收目标第三数据组中的数据。相应地，发送设备可以向接收设备重新发送目标第三数据组中的至少部分数据。
