本申请要求在2021年06月18日提交中国专利局、申请号为PCT/CN2021/101093、申请名称为“一种数据处理方法、装置及系统”的PCT专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其是短距离通信领域，提供了一种数据处理方法、装置及系统。
背景技术
随着全球通信技术的不断发展，无线通信技术呈现出如火如荼的发展态势。基于无线通信技术的智能运输设备、智能家居设备以及机器人等智能终端设备正在逐步进入人们的日常生活中。
现阶段，无线通信系统通常采用Turbo码、低密度奇偶校验码(low density parity check，LDPC)和极化(Polar)码进行信道编解码。对于中短包传输，Turbo码和LDPC码由于自身编解码的特点，在有限码长下很难达到理想的性能。在实现方面，Turbo码和LDPC码在编解码实现过程中具有较高的复杂度。而Polar码是理论上证明可以取得香农容量，且具有相对简单的编解码复杂度的好码，因而得到了越来越广泛的应用。
现阶段，Polar码编/解码编码块后通常还要额外配置速率匹配模块，导致系统设计的复杂度进一步增加，系统功耗进一步增大，影响了Polar码在应用过程中极化信道传输性能的进一步提高。
发明内容
本申请提供一种数据处理方法、装置及系统，用以降低Polar码编/解码的系统功耗。
第一方面，本申请提供一种数据处理方法，该方法适用于具有通信功能的任一通信节点，例如可以用于发送端节点或发送端设备，也可以用于接收端节点或接收端设备。该方法包括：获取信息比特的总数据长度，根据信息比特的总数据长度和预设的第一码率获取C个编码块。其中，C个编码块对应至少一个或多个码长，且至少一个或多个码长属于预先定义或者配置的S个码长，C个编码块的数据长度对应第一码率，S个码长中的每个码长满足2的正整数次幂的形式，S为大于或等于2的正整数，C为正整数。如此，通过使C个编码块匹配Polar编码后的码字所满足的2的正整数次幂形式的码长，有助于使用第一码率直接传输或接收C个编码块编码后的码字，而无需再额外配置速率匹配模块，有效简化Polar码编码/解码的系统设计，进而可降低Polar码编码/解码的系统功耗。
下面分别从发送端设备和接收端设备的角度介绍数据处理方法的具体实现。
第二方面，本申请提供一种数据处理方法，该方法适用于发送端设备，该方法包括：发送端设备获取信息比特，根据信息比特的总数据长度和预设的第一码率获取C个编码块， 并编码C个编码块获得C个编码块编码后的码字，进而发送C个编码块编码后的码字。其中，C个编码块对应至少一个或多个码长，且至少一个或多个码长属于预先定义或者配置的S个码长，C个编码块的数据长度对应第一码率，S个码长中的每个码长满足2的正整数次幂的形式，S为大于或等于2的正整数，C为正整数。在该设计中，通过使C个编码块匹配Polar编码后的码字所满足的2的正整数次幂形式的码长，有助于发送端设备使用第一码率直接传输C个编码块编码后的码字，而无需再额外配置速率匹配模块，有效简化Polar码编码的系统设计，进而可降低Polar码编码的系统功耗。
在一种可能的设计中，发送端设备可采用Polar码编码C个编码块，以利用Polar编码的优点降低编码复杂度，有效提高编码效率。
在一种可能的设计中，针对于第一码率，S个码长中的每个码长可以对应一个预先定义或者配置的数据长度，其中，对应的码长和数据长度可以满足以下内容中的一项或多项：
内容一，S个码长中的最大码长对应的数据长度的值为第一码率和最大码长的乘积。如此，使用每个码率传输最大码长对应的编码块的长度能刚好等于信道所能承受的数据长度，以便发送端设备能充分利用最大码长对数据传输性能的有利性，实现最大码长所对应信道的最佳传输性能。
内容二，S个码长中的非最大码长对应的数据长度的值为第二码率和该非最大码长的乘积，其中，第二码率小于第一码率。如此，通过让使用每个码率传输非最大码长对应的编码块的长度小于信道所能承受的数据长度，还能通过降低码率弥补小码长对数据传输性能的不利影响。
进一步的，实现上述内容二的第二码率可能有多种，例如：
一种可能的设计中，在第一码率为预先定义或者配置的T个码率中的最小码率的情况下，第二码率可以为第一码率与第一预设降阶阈值的差值，在第一码率为预先定义或者配置的T个码率中的非最小码率的情况下，第二码率可以为码率小于第一码率的上一阶码率。其中，第一预设降阶阈值用于指示假设小于最小码率的上一阶码率存在时，上一阶码率相比于最小码率的码率差值，可预先设定或者配置为小于最小码率的一个值。如此，通过使用当前码率的上一阶码率传输非最大码长对应的编码块，能使该编码块的长度尽量和上一阶码率对应的信道所能承受的数据长度相同，且小于当前码率对应的信道所能承受的数据长度，有助于提高非最大码长所对应信道的传输性能。
在上述设计中，发送端设备中预先定义或者配置有S个码长、T个码率、以及S×T个数据长度的对应关系，且该对应关系可以以表格、栈、数据库、队列或其它形式中的一种或多种形式来表示。示例性的，当采用表格形式表示时，如下表1.1示出该设计所对应的S个码长、T个码率、以及S×T个数据长度的对应关系表，其中，表1.1中包含参照母码m 0、m 0-1、……、m 0-S+1所配置的如下S个码长：

另一种可能的设计中，第二码率可以为第一码率和第一码率对应的第二预设降阶阈值的差值。其中，不同码率对应的第二预设降阶阈值可以相同，也可以不同，且具体可根据实际场景进行设置。如此，该设计还能通过灵活配置每个码率对应的第二预设降阶阈值，灵活改变每个码率在非最大码长下的一个数据块的数据长度。

在上述表1.1、表1.2和表1.3中，S个码长可以包括如下码长中的一个或多个：1024bit、512bit、256bit、128bit或者64bit，T个码率可以包括如下码率中的一个或多个：1/4、3/8、1/2、5/8、3/4或7/8。示例性的，当T个码率包括1/4、3/8、1/2、5/8、3/4或7/8中的一个或多个时，第一预设降阶阈值可以预先设定或者配置为小于1/4的一个值，例如可以配置为1/8，如此，无论实际场景中以哪个码率作为最小码率，都能尽量让同一码率和同一码长对应的数据长度保持一致。或者，第一预设降阶阈值也可以配置为1/16、1/32或1/64中的一个，以便使最小码率对应的信道的传输能力尽量接近于最小码率对应的最大传输能力。当T个码率包括1/4、3/8、1/2、5/8、3/4或7/8中的一个或多个时，如果T个码率对应的第二预设降阶阈值设置为同一值，则该第二预设降阶阈值可以设置为小于1/4的一个值，例如可以设置为1/8、1/16、1/32或1/64等，具体不作限定。
在一种可能的设计中，C个编码块中可以包含：C 10个第一编码块，C 10个第一编码块中的每个第一编码块的码长为S个码长中的最大码长，每个第一编码块中包含一个针对于第一编码块所包含的信息比特的第一校验码；和/或，C 20个第二编码块，任一第二编码块的码长为S个码长中的一个非最大码长，C 20个第二编码块中包含一个针对于C 20个第二编码块所包含的全部信息比特的第二校验码；其中，C 10为正整数，且C 20为大于或等于0的整数；或者，C 10为大于或等于0的整数，且C 20为正整数。如此，通过在C个编码块中添加第一校验码和/或第二校验码，能在传输出错时只重传校验码出错的那部分编码块，有助于降低重传的时延。且，通过对最大码长的每个长编码块都添加校验码，但并不对非最大码长的每个短编码块添加校验码，而是对非最大码长的全部短编码块添加一个校验码，还能在添加必要的校验码的同时，尽量减少分段后的编码块的总数据长度，有助于降低空口开销。
在一种可能的设计中，针对于第一码率，在S个码长中的每个码长对应一个预先定义或者配置的数据长度的情况下，C 10和C 20可以是根据信息比特的总数据长度和每个第一编码块中包含的信息比特的数据长度得到的，其中，每个第一编码块中包含的信息比特的数据长度是最大码长对应的数据长度和第一校验码的数据长度之差。如此，通过以最大码长对应的第一编码块为基准确定第一编码块的数量和第二编码块的数量，能尽量使用数据长度更长的第一编码块承载尽可能多的信息比特，有效减少编码块的总数量。
在一种可能的设计中，信息比特的总数据长度和每个第一编码块中包含的信息比特的数据长度的比值为整数的情况下，C 10的取值可以为该比值，而C 20的取值为0，也即是不存在第二编码块。该设计能使用数据长度较长的第一编码块来承载全部的信息比特，有效减少编码块的总数量。
在一种可能的设计中，信息比特的总数据长度和每个第一编码块中包含的信息比特的数据长度的比值不为整数的情况下，C 10的取值可以为该比值中的整数部分，C 20个第二编码块中可以包含L种第二编码块，L种第二编码块对应S个码长中的L个非最大码长，L种第二编码块中的每种第二编码块的数据长度为所对应的非最大码长对应的数据长度，L种第二编码块的数量是根据剩余待分段数据的数据长度和L种第二编码块的数据长度得到的，剩余待分段数据的数据长度是剩余信息比特的数据长度和第二校验码的数据长度之和，剩余信息比特的数据长度为信息比特的总数据长度与C 10个第一编码块中包含的信息比特的数据长度之差。其中，L为小于或等于S-1的正整数。如此，该设计能在第一编码块承载信息比特后存在剩余的情况下，使用数据长度较短的第二编码块来承载剩余的信息比特，相比于使用一个数据长度更长的第一编码块来承载剩余的信息比特来说，有助于减少全部编码块中包含的无用比特位的数量，有效降低空口开销。
在一种可能的设计中，L种第二编码块的数量可以是根据最小码长对应的编码块的预计数量、以及L种第二编码块的数据长度和最小码长对应的数据长度的相对关系确定的，最小码长对应的编码块的预计数量为大于或等于剩余待分段数据的数据长度和最小码长对应的数据长度的比值的最小整数。如此，通过以承载不少于剩余待分段数据的总数据长度的最小编码块的最小数量为基准确定各个非最大码长对应的第二编码块的数量，能保证各个第二编码块将全部的剩余信息比特和第二校验码都包含在内，降低遗漏有效数据的概率。
在一种可能的设计中，发送端设备可以采用比特位数量优先原则确定L种第二编码块的数量，在比特位数量优先原则中，L种第二编码块的数量可以是按照所对应的L个非最大码长由大到小的顺序依次确定的，针对于L种第二编码块中的每种第二编码块：第二编码块的数量可以为最小码长对应的编码块的剩余预计数量与第一比值的比值中的整数，第一比值为第二编码块的数据长度和最小码长对应的数据长度的比值，最小码长对应的编码块的剩余预计数量为最小码长对应的编码块的预计数量与码长大于第二编码块对应的非最大码长的其它非最大码长所对应的第二编码块的数量和第二比值的乘积的差值，第二比值为其它非最大码长对应的第二编码块的数据长度和最小码长对应的数据长度的比值。如此，通过使用各个码长的第一编码块和第二编码块来集中承载信息比特，能尽量让各个第一编码块和第二编码块的总数据长度等于信息比特的总数据长度，有效减少C个编码块中包含的无用比特位的数量，有效节省空口开销。
在一种可能的设计中，L种第二编码块的数量可以是根据最小码长对应的编码块的预 计数量的二进制数据中取值不为0的L个数值确定的，其中，二进制数据由低位到高位的取值一一对应码长由小到大的S-1个非最大码长。如此，该设计利用两个码长对应的数据长度的2的倍数关系，以二进制数据的取值表示各个码长对应的编码块的数量，能尽量通过一次操作确定出各个第二编码块的数量，有效提高数据分段的效率。
在一种可能的设计中，L种第二编码块的数量可以是根据最小码长对应的编码块的预计数量和预设的码长、码率、数据长度、编码块数量和预计数量的对应关系得到的，该对应关系是根据S-1个非最大码长对应的预先设定或者配置的数据长度和最小码长对应的数据长度的相对关系进行预先设定或者配置的。其中，该对应关系可以以表格、数据库或栈等中的任一形式来表示。该设计有助于使发送端设备直接查询对应关系即可获得各个编码块的数量，有效节省计算时延，提高数据分段的效率。
在一种可能的设计中，发送端设备可以采用分段数量优先原则确定L种第二编码块的数量，在分段数量优先原则中，发送端设备在确定L种第二编码块的数量之前，还可以先确定满足如下条件中的一项或多项：剩余待分段数据的数据长度不大于预先设定或者配置的数据长度阈值；或者，最小码长对应的编码块的预计数量不大于预先设定或者配置的数量阈值，最小码长对应的编码块的预计数量为大于或等于剩余待分段数据的数据长度和最小码长对应的预先设定或者配置的数据长度的比值的最小整数。如此，通过在剩余信息比特较少的情况下才采用小码长对应的短编码块进行分段，能在数据传输时延本身较低的情况下通过更精细地分段来减少编码块中包含的无用比特位的数量，有效降低数据传输所产生的空口开销。
在一种可能的设计中，在分段数量优先原则中，当信息比特的总数据长度和每个第一编码块中包含的信息比特的数据长度的比值不为整数时，C 10的取值可以为大于比值的最小整数，C 20的取值可以为0，也即是不存在第二编码块。如此，通过在存在剩余信息比特的情况下，另外使用一个最大码长的第一编码块来承载整个剩余信息比特，相比于使用小码长的第二编码块承载剩余信息比特的方式来说，能减少编码块的总数量，有效降低数据的传输时延。
在一种可能的设计中，在分段数量优先原则中，发送端设备在确定C 10的取值为大于比值的最小整数，C 20的取值可以为0之前，还可以先确定满足如下条件中的一项或多项：剩余待分段数据的数据长度大于预先设定或者配置的数据长度阈值；或者，最小码长对应的编码块的预计数量大于预先设定或者配置的数量阈值，最小码长对应的编码块的预计数量为大于或等于剩余待分段数据的数据长度和最小码长对应的预先设定或者配置的数据长度的比值的最小整数。如此，通过在剩余信息比特较多时才使用一个最大码长的第一编码块来承载整个剩余信息比特，在剩余信息比特较少时仍然使用小码长对应的第二编码块来承载剩余信息比特，能在减少无用比特位的同时，尽量降低重传的数据量和重传时延。
在一种可能的设计中，在分段数量优先原则中，上述条件中的预先设定或者配置预设的数量阈值可以为2 S-1-1，和/或，上述条件中的预先设定或者配置预设的数据长度阈值可以为K S-1×(2 S-1-1)，K S-1为第一码率和最小码长对应的数据长度。如此，通过使用该条件决策是否进行分段，能尽量确保剩余待分段数据分为每个非最大码长所对应的编码块的数量不大于1。
需要指出的是，发送端设备所采用的原则可通过预先设定或配置的方式进行设置，且还可以与接收端设备保持一致，例如通过预先设定或者配置的方式指示发送端设备和接收 端设备采用同一原则，或者由发送端设备向接收端设备发送指示所采用原则的指示消息，以便接收端设备根据该指示消息采用相同的原则进行解码等。其中，指示所采用原则的指示消息可以承载在C个编码块编码后的码字所在的消息中，也可以承载在额外设置的一个消息中，还可以承载在其它信息所在的消息中。另外，指示消息可以以文字、字符、数字或其他形式中的一项或多项来表示，具体不作限定。
在一种可能的设计中，在根据信息比特的总数据长度和预设的第一码率获取C个编码块之后，发送端设备若确定C个编码块的总数据长度与有效数据长度之差不为零，则还可以调整C 10个第一编码块和/或C 20个第二编码块，以便通过调整C个编码块中的无用比特位，节省C个编码块的后续传输时延和空口开销。其中，有效数据长度为信息比特的总数据长度、C 10个第一校验码的数据长度和第二校验码的数据长度之和。
在一种可能的设计中，调整后的C 10个第一编码块或C 20个第二编码块满足如下内容中的一项或多项：调整后的C 10个第一编码块中存在一个或多个第一编码块包含预设数据；调整后的C 10个第一编码块中存在一个或多个第一编码块的数据长度小于最大码长对应的预先设定或者配置的数据长度；调整后的C 20个第二编码块中存在一个或多个第二编码块包含预设数据；或者，调整后的C 20个第二编码块中存在一个或多个第二编码块的数据长度小于第二编码块对应的非最大码长对应的预先设定或者配置的数据长度。如此，该设计通过填充或通过从编码块的数据长度中减去无用比特位的方式调整编码块，能使调整后的编码块尽量匹配真实的信道传输情况。
在一种可能的设计中，在通过在第一编码块中填充预设数据来调整无用比特位的情况下，预设数据可以填充在最后一个第一编码块中包含的信息比特之前，以便通过将无用比特信息填充在第一编码块中的前方位置，有助于将有效信息放在第一编码块中可靠性高的概率比较大的后方位置，有效提升传输有效信息的可靠性。或者，也可以填充在最后一个第一编码块中包含的信息比特和第一校验码之间，以便使第一校验码也能包含无用比特信息的校验信息，进一步提高数据校验和传输的安全性。或者，还可以填充在最后一个第一编码块的第一校验码之后，以便使第一校验码不包含无用比特信息对应的校验信息，有效节省校验操作。
在一种可能的设计中，在通过在第二编码块中填充预设数据来调整无用比特位的情况下，预设数据可以填充在C 20个第二编码块中包含的信息比特之前，也可以填充在C 20个第二编码块中包含的信息比特和第二校验码之间，还可以填充在C 20个第二编码块的第二校验码之后。

为便于理解，先介绍本申请实施例可能用到的部分术语或名词，该术语或名词也作为本申请实施例发明内容的一部分。
(1)Polar码。
在无线通信系统中，Polar码是一种可以取得香农容量且具有较低编译码复杂度的信道编码方式。Polar码的编码策略是利用无噪信道传输对用户有用的信息，且利用全噪信道传输约定的信息或者不传信息。其中，Polar码是一种线性块码，其编码矩阵为F N,编码过程满足
Figure PCTCN2021105608-appb-000009
其中，
Figure PCTCN2021105608-appb-000010
是一个二进制的行矢量，长度为N，N也称为码长；F N是一个N×N的矩阵，且
Figure PCTCN2021105608-appb-000011
这里：
Figure PCTCN2021105608-appb-000012
定义为log 2N个矩阵F 2的克罗内克(Kronecker)乘积。该部分内容所涉及的加法和乘法操作均为二进制伽罗华域(Galois Field)上的加法和乘法操作，本申请对此不作过多介绍。
从Polar码的编码原理可以看出，Polar码的特点是编码后输出的码字所对应的码长为2的正整数次幂。如果编码后输出的码字所对应的码长不满足2的正整数次幂的形式，则还需要在Polar编码和Polar后额外配置速率匹配模块，以便通过速率匹配模块对编码后的码字进行信道重传或打孔，以匹配信道的实际传输能力。
(2)Polar码的母码。
在Polar码编码中，第一步操作即是确定母码长度，母码长度用于指示编码后输出的码字的长度，也称为码长，形式上满足N＝2 m，其中，m是根据速配长度和输入比特长度来确定的。
(3)信息比特、编码块和码字。
本申请实施例中，信息比特是指发送端设备拟发送给接收端设备的信息，编码块是指Polar编码前的信息，而码字是指编码块编码后的信息。其中，编码块中可包含信息比特但不包含校验码，或同时包含信息比特和校验码。在编码块中同时包含信息比特和校验码的情况下，编码块中除去校验码以外的信息即为信息比特。
在Polar码中，业界通常采用两种方式编码信息比特：一种是直接针对整个信息比特生成一个CRC码，并将该CRC码拼接在整个信息比特的后方作为一个编码块，进而对拼接得到的该编码块进行编码；另一种是先对整个信息比特进行均匀分段，再针对于分出的每个数据段生成一个CRC码，将生成的CRC码拼接在所对应的数据段的后方作为一个编码块，然后对拼接得到的各个编码块进行编码。然而，无论是不分段还是均匀分段，都无法准确匹配Polar编码后的码字所需满足的2的正整数次幂的码长，导致Polar编码或Polar解码后都需要额外配置速率匹配模块以实现码长的调整，不利于降低系统设计的复杂度和系统功耗。
有鉴于此，本申请提供一种数据处理方法，用于根据信息比特的总数据长度和预设的第一码率获得一个或多个编码块，并使一个或多个编码块匹配Polar编码后的码字所满足的2的正整数次幂的码长，以便能使用第一码率直接传输或接收一个或多个编码块编码后的码字，而可不必再额外添加速率匹配模块，有效降低系统设计的复杂度和系统功耗。
下面将结合附图对本申请作进一步地详细描述。应理解，方法实施例中的具体操作方法也可以应用于装置实施例或系统实施例中。需要说明的是，在本申请的描述中，多个是指两个或两个以上。鉴于此，本申请实施例中也可以将“多个”理解为“两个或两个以上”。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。
另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。例如，“第一编码块”是指最大码长对应的编码块，而“第二编码块”是指非最大码长对应的编码块，“第一编码块”和“第二编码块”只是指示编码块的码长是否为最大码长，并不能理解为其优先级或重要程度不同，也不能理解为暗示其顺序不同。
【实施例一】
图3示例性示出本申请实施例提供的一种数据处理方法的交互流程示意图，该方法适用于发送端设备和接收端设备，发送端设备和接收端设备可以是任意两个支持本申请实施例中的通信功能的装置、节点或芯片等。如图3所示，该流程包括如下步骤：
步骤301，发送端设备获取信息比特。
在上述步骤301中，信息比特是指发送端设备拟发送给接收端设备的信息比特，该信息比特可以是数据信息，也可以是控制信息，还可以是系统信息，具体不作限定。
步骤302，发送端设备根据信息比特的总数据长度和预设的第一码率获取C个编码块， 其中，C个编码块对应一个或多个码长，且一个或多个码长属于预先定义或者配置的S个码长，C个编码块的数据长度对应第一码率，S个码长中的每个码长满足2的正整数次幂的形式，S为大于或等于2的正整数，C为正整数。
在上述步骤302中，信息比特的总数据长度是指发送端设备拟发送给接收端设备的信息比特的总比特位数，例如拟发送的信息比特共300bit时，信息比特的总数据长度即是300bit。另外，预设的第一码率可以是传输格式所要求的码率，也可以是根据需求人为选择的一个码率，还可以是按照规则从预先定义或者配置的多个码率中选出的一个码率，其中的规则例如可以是轮询选取或者随机选取等，具体不作限定。
一种可能的实现方式中，发送端设备中预先定义或者配置有S个码长、T个码率、以及S×T个数据长度的对应关系，S×T个数据长度中的每个数据长度可对应S个码长中的一个码长和T个码率中的一个码率，用于表征预先设定或者配置的使用所对应码率传输所对应码长的编码块时的一个编码块的数据长度，S和T均为大于或等于2的正整数。其中，S个码长可以是参照母码长度进行预先设定或者配置的，例如预先根据常用的速配长度和输入比特长度确定出目前常用的S个m，然后按照N＝2 m的形式计算出与目前常用的S个m对应的S个母码长度，作为S个码长。T个码率可以参照目前常用的码率进行预先设定或者配置，T个码率通常也称为T阶码率，码率的阶数越高则码率越大。且，在同一码率下，预先定义或者配置的数据长度会随着码长的增大而增大，且随着码长的减小而减小。也即是说，在同一码率下，预先定义或者配置的数据长度与码长成正相关关系，大码长会对应大编码块，而小码长则对应小编码块。
进一步的示例性的，通信领域中的信道所能承受的数据长度为码长和码率的乘积，而信道的传输性能与码长成正相关关系，且与码率成负相关关系。也即是说，当码长越小时，信道的数据传输性能越差，当码率越小时，信道的数据传输性能越好。基于此，S个码长和T个码率对应的S×T个数据长度还可以参照如下原则进行预先设定或者配置：针对于任一码率，S个码长中的最大码长对应的数据长度为当前码率和最大码长的乘积，S个码长中的非最大码长对应的数据长度为小于当前码率的一个码率和非最大码长的乘积。如此，通过让使用每个码率传输最大码长对应的编码块的长度刚好等于信道所能承受的数据长度，能充分利用最大码长对数据传输性能的有利性实现最大码长所对应信道的最佳传输性能。且，通过让使用每个码率传输非最大码长对应的编码块的长度小于信道所能承受的数据长度，还能通过降低码率弥补小码长对数据传输性能的不利影响。
在上述示例中，小于当前码率的一个码率可以根据实际场景进行设定或者配置，也可以由本领域技术人员根据经验进行设定或者配置，具体不作限定。一种可能的实现方式中，假设预先设定或者配置了如下S个码长：
Figure PCTCN2021105608-appb-000013
Figure PCTCN2021105608-appb-000014

本申请实施例中，S个码长、T个码率、以及S×T个数据长度的对应关系可以以表格、栈、数据库、队列或其它形式中的一种或多种来表示。示例性的，当以表格形式表示时，表1.1示出按照对应关系一设定或配置的S个码长、T个码率、以及S×T个数据长度的对应关系表，该对应关系表也称为分段长度参照表，或简称为K表。
表1.1:一种分段长度参照表(K表)
Figure PCTCN2021105608-appb-000015
参照表1.1所示，一个码长和一个码率对应的预先设定或者配置的数据长度可满足如下形式中的一项或多项：
1，最大码长N 0和任一码率R i对应的预先设定或者配置的数据长度K 0,i满足如下公式(3.1)：
K 0,i＝N 0×R i……(3.1)
其中，i为大于或等于0且小于或等于T-1的整数。
2，任一非最大码长N j和最小码率R 0对应的预先设定或者配置的数据长度K j,0满足如下公式(3.2)：
K j,0＝N j×(R 0-D 0)……(3.2)
其中，D 0为第一预设降阶阈值，用于指示假设小于最小码率的上一阶码率存在时，上一阶码率相比于最小码率的码率差值，可预先设定或者配置为小于最小码率R 0的一个值；j为小于或等于S-1的正整数。
3，任一非最大码长N j和任一非最小码率R z对应的预先设定或者配置的数据长度K j,z满足如下公式(3.3)：
K j,z＝N j×R z-1……(3.3)
其中，R z-1为码率小于R z的上一阶码率，Z为小于或等于T-1的正整数。
示例性的，目前常用的码长主要包括：1024bit、512bit、256bit、128bit或者64bit中一个或多个，目前常用的码率主要包括：1/4、3/8、1/2、5/8、3/4和/或7/8。考虑到这些码率中任意相邻的两种码率间隔都为1/8，因此可预先设定或者配置第一预设降阶阈值D 0为1/8，如此，无论实际场景中以哪个码率作为最小码率，都能尽量让K表保持一致。举例来说，当第一预设降阶阈值D 0为1/8时，一种可能的场景中，如果码长包括如上五种码长，且码率包括如上六种码率，则表1.1中的K表可具体表示为如下表2.11(A)所示，计算结果参照如下表2.11(B)所示。当预设的降阶阈值D 0为1/8时，另一种可能的场景中，如果码长包括如上五种码长，而码率包括3/8、1/2、5/8、3/4和7/8，则表1.1中的K表可具体表示为如下表3.11(A)所示，计算结果参照如下表3.11(B)所示。对比表2.11(B)和表3.11(B)可知，表2.11(B)中的最小码率为1/2，表3.11(B)中的最小码率为3/8， 虽然两个最小码率不同，但表3.11(B)也只是比表2.11(B)中少了1/2所对应的那行数据，其它码率所对应的数据长度则仍与表2.11(B)保持一致。

应理解，第一预设降阶阈值D 0也可以设置为其它值，例如1/16、1/32、1/64等。举例来说，当设置为1/16时，一种可能的场景中，如果码长包括如上五种码长，且码率包括如上六种码率，则表1.1中的K表可具体表示为如下表2.12(A)所示，计算结果参照如下表2.12(B)所示。当第一预设降阶阈值D 0为1/16时，另一种可能的场景中，如果码长包括如上五种码长，而码率包括3/8、1/2、5/8、3/4和7/8，则表1.1中的K表可具体表示为如下表3.12(A)所示，计算结果参照如下表3.12(B)所示。

比较表2.11(B)和表2.12(B)可知，第一预设降阶阈值D 0设置的越大，则最小码率在非最大码长下的一个编码块的数据长度会越小，第一预设降阶阈值D 0设置的越小，则最小码率在非最大码长下的一个编码块的数据长度会越大。此外，第一预设降阶阈值D 0影响的最小码率对应的数据长度，而不会影响到其它码率随对应的数据长度。
对应关系二
本申请实施例中，S个码长、T个码率、以及S×T个数据长度的对应关系可以以表格、栈、数据库、队列或其它形式中的一种或多种来表示。示例性的，当以表格形式表示时，表1.2示出按照对应关系二设定或配置的S个码长、T个码率、以及S×T个数据长度的对应关系表，该对应关系表称为分段长度参照表，或简称为K表。
表1.2:另一种分段长度参照表(K表)
Figure PCTCN2021105608-appb-000025
参照表1.2所示，在对应关系二中，一个码长和一个码率对应的预先设定或者配置的数据长度可满足如下形式中的一项或多项：
1，最大码长N 0和任一码率R i对应的预先设定或者配置的数据长度K 0,i满足如下公式(3.4)：
K 0,i＝N 0×R i……(3.4)
其中，i为大于或等于0且小于或等于T-1的整数。
2，任一非最大码长N j和任一码率R i对应的预先设定或者配置的数据长度K j,i满足如下公式(3.5)：
K j,i＝N j×(R i-P i)……(3.5)
其中，P i为码率R i对应的第二预设降阶阈值，用于指示采用比当前码率低多少的码率传输当前码率对应的码块，可预先设定或者配置为小于码率R i的一个值；j为小于或等于S-1的正整数。
需要说明的是，在对应关系二中，不同码率对应的第二预设降阶阈值可以相同，也可以不同，具体不作限定。其中，当各个码率对应的第二预设降阶阈值相同时，第二预设降阶阈值可以设置为小于各个码率中的最小码率的一个值。例如，考虑到目前场景的码长包 括：1024bit、512bit、256bit、128bit和64bit中的一项或多项，目前常用的码率包括：1/4、3/8、1/2、5/8、3/4和/或7/8，因此，各个码率对应的第二预设降阶阈值可以设置为小于目前常用的这些码率中的最小码率1/4的一个值，例如可以设置为1/8、1/16、1/32或1/64等。假设各个码率对应的第二预设降阶阈值均设置为1/16，则一种场景下，如果码长包括1024bit、512bit、256bit、128bit和64bit，码率包括1/4、3/8、1/2、5/8、3/4和7/8，则表1.2中的K表可具体表示为如下表2.21(A)所示，计算结果参照如下表2.22(B)所示。另一种场景下，如果码长包括1024bit、512bit、256bit、128bit和64bit，码率包括3/8、1/2、5/8、3/4和7/8，则表1.2中的K表可具体表示为如下表3.21(A)所示，计算结果参照如下表3.22(B)所示。

应理解，上述只是以各个码率对应的第二预设降阶阈值均为1/16为例举例一种对应关系二的可能情况，第二预设降阶阈值设置为不同值或者设置为相同值但不为1/16的情况可参照上述内容实现，此处不再重复一一赘述。且，对应关系二还能通过灵活配置每个码率对应的第二预设降阶阈值，灵活改变每个码率在非最大码长下的一个数据块的数据长度。例如，在需要小码块也能承载较大数据量的场景中，每个码率对应的第二预设降阶阈值可以设置为一个较小的值，以便增大每个码率在非最大码长下的一个小数据块的数据长度。在需要小码块承载较少数据量的场景中，每个码率对应的第二预设降阶阈值可以设置为一个较大的值，以便减小每个码率在非最大码长下的一个小数据块的数据长度。在需要某个码率承载较大数据量而其它码率承载较小数据量的场景下，该码率对应的第二预设降阶阈值可以设置为较小的值，而其它码率对应的第二预设降阶阈值可以设置为较大的值。可见，上述对应关系二可以兼容于各种传输场景，有助于提高在通信领域中的通用性。
对应关系三

表1.3:又一种分段长度参照表(K表)

参照表1.3所示，在对应关系三中，一个码长和一个码率对应的预先设定或者配置的数据长度可满足如下形式中的一项或多项：
1，最大码长N 0和任一码率R i对应的预先设定或者配置的数据长度K 0,i满足如下公式(3.4)：
K 0,i＝N 0×R i……(3.6)
其中，i为大于或等于0且小于或等于T-1的整数。
2，任一非最大码长N j和任一码率R i对应的预先设定或者配置的数据长度K j,i满足如下公式(3.5)：
K j,i＝N j×λ iR i……(3.7)
其中，λ i为码率R i对应的预设码率占比，用于指示利用多大比例关系的当前码率传输当前码率对应的码块，可预先设定或者配置为大于0且小于1的一个值；j为小于或等于S-1的正整数。
需要说明的是，在对应关系三中，不同码率对应的预设码率占比可以相同，也可以不同，具体不作限定。优选地，可以设置各个码率对应的预设码率占比相同，以便使各个码率对应的编码块的数据长度能随着各个码率的变化而稳定变化。假设各个码率对应的预设码率占比均设置为1/2，则一种场景下，如果码长包括1024bit、512bit、256bit、128bit和64bit，码率包括1/4、3/8、1/2、5/8、3/4和7/8，则表1.3中的K表可具体表示为如下表2.31(A)所示，计算结果参照如下表2.32(B)所示。另一种场景下，如果码长包括1024bit、512bit、256bit、128bit和64bit，码率包括3/8、1/2、5/8、3/4和7/8，则表1.3中的K表可具体表示为如下表3.31(A)所示，计算结果参照如下表3.32(B)所示。

应理解，上述只是以各个码率对应的预设码率占比均为1/2为例举例一种对应关系三的可能情况，预设码率占比设置为不同值或者设置为相同值但不为1/2的情况可参照上述内容实现，此处不再重复一一赘述。且，对应关系三也能通过灵活配置每个码率对应的预设码率占比，灵活改变每个码率在非最大码长下的一个数据块的数据长度。例如，在需要小码块也能承载较大数据量的场景中，每个码率对应的预设码率占比可以设置为一个较大的值，以便增大每个码率在非最大码长下的一个小数据块的数据长度。在需要小码块承载较少数据量的场景中，每个码率对应的预设码率占比可以设置为一个较小的值，以便减小每个码率在非最大码长下的一个小数据块的数据长度。在需要某个码率承载较大数据量而其它码率承载较小数据量的场景下，该码率对应的预设码率占比可以设置为较大的值，而其它码率对应的预设码率占比可以设置为较小的值。可见，上述对应关系三也可以兼容于各种传输场景，有助于提高在通信领域中的通用性。
应理解，上述只是示例性的介绍三种可能的对应关系，在实施中，S个码长、T个码率和S×T个数据长度还可以具有其它的对应关系，凡是能够实现以一个小于当前码率的码率确定当前码率在非最大码长下的一个编码块的数据长度的方案，均在本申请的保护范围内，本申请对此不再一一列举。
需要指出的是，针对本申请实施例所给出的每个表，例如无论是上述内容所示出的表1.1、表1.2、表2.11(A)至表3.32(B)，还是后续出现的表4(A)至表4(F)、表5(A)至表5(F)，都只是给出各自场景下最大可满足的一种形式，但实际上每个表中都可以包含其中的一行或多行，或者包含其中的一列或多列，未必每行和每列都要满足，本申请对此不作具体限定。另外，表只是对应关系的一种可能的承载形式，实际操作中还可以使用其它承载形式来表征对应关系，例如数据库、数据栈或队列等，本申请对此也不作具体限定。
基于上述任一K表，在实施中，假设第一码率为1/2，则发送端设备可先从K表中获得码率1/2所在的那一行中5个码长各自对应的预先设定或者配置的数据长度，然后按照预先设定或者配置的分段原则，利用信息比特的总数据长度和5个码长各自对应的预先设定或者配置的数据长度获得C个编码块。其中，C个编码块可以对应一个或多个码长，例 如C个编码块都对应同一码长，或者C个编码块中存在两个或两个以上的编码块对应不同的两个码长。此处的编码块与码长对应是指编码块的数据长度与该码长对应的预先设定或者配置的数据长度相同。如此，由于K表中的码长是按照Polar编码时采用的母码长度预先设定或者配置的，因此该分段方式实际上是按照母码长度来对信息比特进行分段的，进而能使分段后的每个编码块直接匹配Polar编码的母码长度，而不需要再进行速率匹配。
本申请实施例中，不同的分段原则可对应不同的分段结果，为便于理解，图4示例性示出本申请实施例提供的一种不同分段原则下的分段后数据呈现形式图，该示例中，假设码长N 0对应的一个编码块的数据长度为K 0，码长N 1对应的一个编码块的数据长度为K 1，……，码长N S-1对应的一个编码块的数据长度为K S-1，CRC 0、CRC 1、……、CRC S-1、CRC ls是指校验码的长度，并不代表实际的校验码内容，例如最大码长N 0对应的每个编码块中的信息比特对应的校验码的长度都称为CRC 0，但这只是指示最大码长N 0对应的各个编码块中的校验码的长度相同，并不意味着最大码长N 0对应的各个编码块中的校验码内容相同。参见图4中(A)至图4中(C)所示，其中：
图4中(A)示出一种不需要添加校验码的分段后数据呈现形式图，如图4中(A)所示，该示例对应的分段原则为：根据信息比特的总数据长度获得C 0a个码长N 0对应的编码块、C 1a个码长N 1对应的编码块、……、C (S-1)a个码长N S-1对应的编码块，且每个编码块中包含信息比特但不包含校验码。按照该分段原则，每个编码块的数据长度即为该编码块中包含的信息比特的数据长度。一种可能场景中(为便于介绍，简称为场景一)，假设信息比特的总数据长度为584bit，第一码率为1/2，则基于表2.11(B)给出的K表可知，1/2码率在1024bit码长、512bit码长、256bit码长、128bit码长和64bit码长下的一个编码块的数据长度分别为512bit、192bit、96bit、48bit和24bit，因此，分段后的C个编码块可以包括：1个1024bit码长对应的数据长度为512bit的编码块，1个128bit码长对应的数据长度为48bit的编码块和1个64bit码长对应的数据长度为24bit的编码块。
图4中(B)示出一种需要添加校验码的分段后数据呈现形式图，如图4中(B)所示，该示例对应的分段原则为：根据信息比特的总数据长度获得C 0b个码长N 0对应的编码块、C 1b个码长N 1对应的编码块、……、C (S-1)b个码长N S-1对应的编码块，且每个编码块中都包含信息比特和针对于所包含的信息比特的一个校验码，同一码长对应的各个编码块中的校验码的数据长度相同，例如C 0b个码长N 0对应的编码块中的校验码的数据长度都为CRC 0，C 1b个码长N 0对应的编码块中的校验码的数据长度都为CRC 1，……。按照该分段原则，每个编码块的数据长度为该编码块中包含的信息比特的数据长度和校验码的数据长度之和。仍以上述场景一为例，假设预先设定或者配置的校验码的数据长度为24bit，则分段后的C个编码块可以包括：1个1024bit码长对应的数据长度为512bit的编码块，该编码块中包括488bit的信息比特和24bit的校验码；1个256bit码长对应的数据长度为96bit的编码块，该编码块中包括72bit的信息比特和24bit的校验码；1个128bit码长对应的数据长度为48bit的编码块，该编码块中包括24bit的信息比特和24bit的校验码。
图4中(C)示出另一种需要添加校验码的分段后数据呈现形式图，如图4中(C)所示，该示例对应的分段原则为：根据信息比特的总数据长度获得C 10个码长N 0对应的第一编码块和C 20个码长N 1～码长N S-1中的L个码长对应的第二编码块，C 10个第一编码块的每个第一编码块中包含信息比特和针对于所包含的信息比特的第一校验码，且每个第一编码块中包含的第一校验码的数据长度都为CRC 0，C 20个第二编码块中包含除C 10个第一编码 块所包含的信息比特以外的剩余信息比特和针对于剩余信息比特的一个第二校验码，第二校验码的数据长度为CRC ls，L为大于或等于0的正整数，C 10为正整数且C 20为大于或等于0的整数，或者C 10为大于或等于0的整数且C 20为正整数。按照该分段原则，每个第一编码块的数据长度为该第一编码块中包含的信息比特的数据长度和第一校验码的数据长度之和，而C 20个第二编码块的数据长度为C 20个第二编码块中包含的信息比特的数据长度和第二校验码的数据长度。仍以上述场景一为例，假设预先设定或者配置的第一校验码的数据长度CRC 0和第二校验码的数据长度CRC ls都为24bit，则分段后的C个编码块可以包括：1个1024bit码长对应的数据长度为512bit的第一编码块，该第一编码块中包括488bit的信息比特和24bit的第一校验码；1个256bit码长对应的数据长度为96bit的第二编码块，该第二编码块中包括96bit的信息比特；1个64bit码长对应的数据长度为24bit的第二编码块，该第二编码块中包括24bit的第二校验码。
比较上述三种分段原则：图4中(A)所采用的分段原则由于并未添加校验码，因此在传输出错时只能重传全部的信息比特，而图4中(B)和图4中(C)所采用的分段原则由于添加了校验码，因此在传输出错时可只重传校验码出错的那部分编码块，从而有助于降低重传的时延；且，图4中(B)所采用的分段原则针对于每个编码块都添加了校验码，而不考虑编码块的长短，而图4中(C)所采用的分段原则对最大码长N 0的每个长编码块都添加校验码，但并不对非最大码长的每个短编码块添加校验码，而是对非最大码长的全部短编码块添加一个校验码，该分段原则有助于在添加必要的校验码的同时，减少分段后的编码块的总数据长度，有助于降低空口开销。
另外，需要指出的是，上述给出的示例都是尽量使用大码长对应的大编码块承载尽可能多的信息比特，如此可减少编码块的数量。当然，如果不考虑编码块的数量，同一分段原则下还可以有很多种分段方式，例如，按照图4中(C)所采用的分段原则，上述场景一对应的分段后的C个编码块还可以包括：两个1024bit码长对应的数据长度为512bit的第一编码块，这两个第一编码块的数据长度共计1024bit，每个第一编码块的512bit中存在24bit用于承载各自的第一校验码，而两个第一编码块剩下的976bit中存在584bit用于承载信息比特，剩下的392bit为无用比特位，该无用比特位后续可进行填充或从数据长度中减去，而至于无用比特位具体在哪个第一编码块中操作，则不作限定。当同一分段原则中存在多种分段结果时，最终选择哪种分段形式，则可根据实际需求来决定，例如，若需要尽可能地减少无用比特位的数量以降低空口开销，则可选择1个1024bit码长对应的第一编码块、1个256bit码长对应的编码块和1个64bit码长对应的编码块的那种分段结果，若需要尽可能地少分段以降低传输复杂度，则可选择2个1024bit码长对应的第一编码块的那种分段结果。
步骤303，发送端设备编码C个编码块，获得C个编码块编码后的码字。
在上述步骤303中，发送端设备在按照所使用的分段原则确定分段结果(例如包括几个第一编码块、几个第二编码块、每个第一编码块中包含的信息比特的数据长度、以及每个第二编码块中包含的信息比特的数据长度等)后，可按照分段结果拆分整个信息比特，并根据拆分获得的各段信息比特构建C个编码块(一个编码块中可能包含信息比特，也可能不包含信息比特，而是仅用于承载CRC)，以及根据分段原则对C个编码块中的一个或多个编码块附加CRC，并对附加CRC后的编码块进行Polar码编码，以获得每个编码块的码字。
示例性的，发送端设备在获得C个编码块后，还可以执行比特映射、高阶调制或符号交织等操作中的一项或多项。其中，编码C个编码块、比特映射、高阶调制或符号交织等操作的顺序不作具体限定，例如这些操作可以是一次执行完成的，也可以是依次执行的，还可以是并行执行的。一种可能的实现方式中，在上述一项或多项操作完成后，C个编码块的码字会形成一个完整的序列，该序列中的各个第一编码块的码字和各个第二编码块的码字可以按照预先设定或者配置的顺序拼接在一起，且该顺序还可以预先设定或者配置给接收端设备，或者由发送端设备通过消息方式通知给接收端设备，以便接收端设备后续也能按照相同的顺序拆分以获得整个信息比特。关于这几个操作的具体实现，本申请对此不作过多介绍和限定。
需要说明的是，针对于一个编码块来说，该编码块的数据长度是指编码该编码块之前该编码块所包含的比特位数，而码长则是指编码编码块后所获得的编码块中的码字的比特位数。例如，如果一个编码块对应的数据长度为384bit，对应的码长为1024bit，则意味着该编码块在编码前包含384bit的数据，而编码后包含1024bit的码字。如此，由于发送端设备是按照预先设定或者配置的满足的2的正整数次幂的码长来获得编码块的，因此，每个编码块编码后的码长都能匹配Polar编码后的码字所满足的2的正整数次幂的码长，从而发送端设备可无需再对附加CRC后的编码块进行速率匹配，即可编码并发送编码块编码后的码字。
步骤304，发送端设备将C个编码块编码后的码字发送给接收端设备。
示例性的，发送端设备可以将C个编码块的码字承载在消息中，并通过信道发送给接收端设备。其中，C个编码块的码字在消息中可呈现为一个完整的序列，还需要接收端设备从该序列中分段出C个编码块各自的码字。
步骤305，接收端设备根据信息比特的总数据长度和预设的第一码率，解码C个编码块编码后的码字，获得C个编码块中包含的信息比特。
在上述步骤305中，信息比特的总数据长度可以是发送端设备通过消息发送给接收端设备的，接收端设备解析该消息即可获得信息比特的总数据长度。其中，承载信息比特的总数据长度的消息可以是承载C个编码块编码后的码字的消息，也可以是其它消息，例如是额外发送的一个消息，或者是承载其它信息的消息等，具体不作限定。
示例性的，当C个编码块的码字呈现为一个完整的序列时，接收端设备接收到承载该序列的消息后，可以根据信息比特的总数据长度和预设的第一码率，按照与发送端设备一致的分段原则确定分段结果，并根据分段结果中指示的各种编码块的数量以及各个编码块的码长(例如第一编码块的数量、每个第一编码块的码长、各个第二编码块的数量和/或每个第二编码块的码长等)，对该消息中承载C个编码块编码后的码字的序列进行分段，获得每个编码块编码后的码字，进而解码C个编码块编码后的码字，获得C个编码块。其中，接收端设备获得C个编码块编码后的码字后，还可以执行符号解交织、高阶解调或比特映射等操作中的一项或多项。其中，解码C个编码块编码后的码字、符号解交织、高阶解调或比特映射等操作顺序不作具体限定，例如这些操作可以是一次执行完成的，也可以是依次执行的，还可以是并行执行的。关于这几个操作的具体实现，本申请对此不作过多介绍和限定。
进一步示例性的，当C个编码块编码后的码字是发送端设备采用Polar码编码C个编码块所得到的时，接收端设备可以采用相对应的Polar码解码C个编码块编码后的码字， 获得C个编码块。且，接收端设备按照与发送端设备一致的分段原则所确定的分段结果中还可以包含每个编码块中包含的信息比特的数据长度和校验码的数据长度，如此，接收端设备还可以根据分段结果，从每个编码块中获得信息比特和/或校验码。且，在包含校验码的情况下，接收端设备还可对编码块进行校验。例如，当校验码为CRC校验码时，如果发送端设备使用生成多项式获得CRC校验码，则每个CRC校验码对应的一个或多个编码块必然可被生成多项式整除。因此，接收端设备可使用同样的生成多项式(生成多项式是发送端设备和接收端设备预先约定好的，在发送端设备和接收端设备的整个传输过程中保持不变)和CRC校验码对应的一个或多个编码块相除，如果余数为0，意味着该CRC校验码对应的一个或多个编码块没有错误，接收端设备可获得该一个或多个编码块中包含的信息比特。反之，如果余数不为0，意味着该CRC校验码对应的一个或多个编码块中存在一个或多个比特位出错，接收端设备可要求发送端设备重传CRC校验不通过的编码块，待重传无误后再进行级联。
进一步示例性的，当C个编码块都没有错误时，接收端设备还可将C个编码块中包含的信息比特进行级联，获得完整的信息比特，该完整的信息比特即为发送端设备拟发送给接收端设备的信息比特，接收端设备可使用该完整的信息比特完成后续的相关操作。需要指出的是，级联只是一种示例，在实际操作中也可以不级联，例如也可以单独使用每个编码块中包含的信息比特完成与每个编码块相关的操作，或者也可以级联部分编码块中包含的信息比特完成与该部分编码块相关的操作等等，具体不作限定。
在上述实施例一中，通过使C个编码块匹配Polar编码后的码字所满足的2的正整数次幂的码长，能在Polar编/解码后直接传输或接收C个编码块编码后的码字，而不必再额外配置速率匹配模块，有效简化Polar编/解码的系统设计，进而降低Polar编/解码的系统功耗。
下面以图4中(C)所示意的分段原则为例，基于实施例二介绍数据处理方法的进一步实现。
【实施例二】
图5示例性示出本申请实施例提供的另一种数据处理方法的交互流程示意图，该方法适用于发送端设备和接收端设备，发送端设备和接收端设备可以是任意两个支持本申请实施例中的通信功能的装置、节点或芯片等。如图5所示，该流程包括如下步骤：
步骤501，发送端设备获取信息比特。
步骤502，发送端设备根据预设的第一码率在最大码长下的预先设定或者配置的数据长度和预先设定或者配置的第一校验码的数据长度，确定一个第一编码块中包含的信息比特的数据长度。
在上述步骤502中，基于图4中(C)所示意的分段原则可知，每个第一编码块由信息比特和一个针对于该第一编码块中包含的信息比特的第一校验码构成，也即是说，每个第一编码块的数据长度等于该第一编码块中包含的信息比特的数据长度和第一校验码的数据长度之和，因此，每个第一编码块中包含的信息比特的数据长度也即等于该第一编码块的数据长度与该第一编码块中包含的第一校验码的数据长度之差。基于此，假设预先设定或者配置的第一校验码的数据长度为CRC 0，K表中规定预设的第一码率在最大码长N 0下的预先设定或者配置的数据长度为K 0(即K表中规定一个第一编码块的数据长度为K 0)，则一个第一编码块中包含的信息比特的数据长度为：K 0-CRC 0。
步骤503，发送端设备判断信息比特的总数据长度和一个第一编码块中包含的信息比特的数据长度的比值是否为整数，若是，则执行步骤504，若否，则执行步骤505。
步骤504，发送端设备确定第一编码块的数量为该比值，第二编码块的数量为0(即不存在第二编码块)，之后执行步骤507。
在上述步骤504中，信息比特的总数据长度和一个第一编码块中包含的信息比特的数据长度的比值为整数，意味着信息比特刚好可以全部由第一编码块来承载，而不存在剩余的信息比特。该情况下，发送端设备可直接将该比值作为第一编码块的数量C 10，且将第二编码块的数量设置为0，之后跳转至步骤507。此情况下，由于第二编码块的数量为0，也即是不存在第二编码块，因此分段后的C个编码块全部为第一编码块，C 10等于C。
步骤505，发送端设备将不大于该比值的最大整数作为第一编码块的初始数量，根据信息比特的总数据长度、初始数量的第一编码块中包含的信息比特的数据长度、以及预先设定或者配置的第二校验码的数据长度确定剩余待分段数据的数据长度。
在上述步骤505中，假设信息比特的总数据长度为K input，则第一编码块的初始数量C 0'可满足如下公式(5.1)：
C 0'＝floor(K input/(K 0-CRC 0))……(5.1)
其中，floor()是向下取整函数，也称为向下舍入或向零取舍，即取不大于括号中的数值的最大整数，例如floor(1.5)即是取不大于1.5的最大整数，计算的结果为1，floor(2)即是取不大于2的最大整数，计算结果为2。如此，通过上述公式(5.1)所计算出的第一编码块的初始数量，可用于指示承载不超过信息比特的总数据长度的第一编码块的最大数量。
进一步的，信息比特的总数据长度为K input，而初始数量C 0'个第一编码块中的每个第一编码块包含的信息比特的数据长度为K 0-CRC 0，因此，除C 0'个第一编码块所包含的信息比特以外的剩余信息比特的数据长度K ls可满足如下公式(5.2)：
K ls＝K input-C 0'×(K 0-CRC 0)……(5.2)
基于图4中(C)所示出的分段原则可知，剩余信息比特的后方还会附加一个针对于整个剩余信息比特的第二校验码，也即是说，剩余待分段数据由剩余信息比特和第二校验码构成，假设预先设定或者配置的第二校验码的数据长度为CRC ls，则剩余待分段数据的数据长度D ls可满足如下公式(5.3)：
D ls＝K ls+CRC ls……(5.3)
其中，剩余待分段数据未来可能会承载于C 20个第二编码块，也可能会承载于一个第一编码块。
为便于理解，以一个具体的场景(简称为场景二)，举例说明上述计算过程：假设信息比特的总数据长度为1000bit，第一校验码的数据长度和第二校验码的数据长度被预先设定或者配置为24bit，且第一码率为3/8，则查询表2.11(B)所示出的K表可知，3/8码率在最大码长1024bit下的预先设定或者配置的数据长度为384bit，也即是说，K表规定在3/8码率下最大码长1024bit对应的一个第一编码块的长度为384bit；如此，一个第一编码块中包含的信息比特的数据长度为：384bit-24bit＝360bit，信息比特的总数据长度1000bit和一个第一编码块中包含的信息比特的数据长度360bit的比值为1000/360，约为2.78，由于该比值2.78不为整数，因此可确定第一编码块的初始数量为不大于该比值2.78的最大整数，即2；进一步的，由于该比值2.78不为整数，意味着除2个第一编码块中所包含的 信息比特之外，还存在一部分剩余信息比特，该部分剩余信息比特的数据长度为：1000bit-2×360bit＝280bit；由于剩余信息比特后还会拼接一个第二校验码，因此剩余待分段数据的数据长度为：280bit+24bit＝304bit。
步骤506，发送端设备根据第一编码块的初始数量、剩余待分段数据的数据长度和预设的第一码率在各个非最大码长下的预先设定或者配置的数据长度，确定第一编码块的数量和各个非最大码长对应的第二编码块的数量。
示例性的，发送端设备可采用分段数量优先原则或比特位数量优先原则来确定第一编码块的数量和各个非最大码长对应的第二编码块的数量。其中，发送端设备所采用的原则可通过预先设定或配置的方式进行设置，且还可以与接收端设备保持一致，例如通过预先设定或者配置的方式指示发送端设备和接收端设备采用同一原则，或者由发送端设备向接收端设备发送指示所采用原则的指示消息，以便接收端设备根据该指示消息采用相同的原则进行解码等。其中，指示所采用原则的指示消息可以承载在C个编码块编码后的码字所在的消息中，也可以承载在额外设置的一个消息中，还可以承载在其它信息所在的消息中。另外，指示消息可以以文字、字符、数字或其他形式中的一项或多项来表示，例如一种可能的示例中，当指示消息为0时，意味着发送端采用的是分段数量优先原则，当指示消息为1时，意味着发送端采用的是比特位数量优先原则。保持发送端和接收端采用同一原则的方式有很多，此处不再一一赘述。
进一步地，在分段数量优先原则中，参照表1.1所示意的K表，考虑到最大码长对应的数据长度是根据当前码率确定的，而非最大码长对应的数据长度是根据上一阶码率确定的，因此，当待分段数据较多时，如果将待分段数据划分到非最大码长对应的短编码块中，则这些短编码块折算在当前码率下的码长可能已超过最大码长，进而导致编码块的传输时延较大，因此想要保证较小的传输时延，则需要控制编码块的数量不能过多。在比特位数量优先原则中，如果编码块中包含的无用比特位的数量越多，则在各编码块码率相差不大时，传输该编码块时所需的空口损耗也就越大，因此想要保证较低的空口损耗，则需要控制分段后的C个编码块的总数据长度尽量接近有效数据的总数据长度。其中，有效数据包括信息比特、以及第一校验码和/或第二校验码。下面分别对这两种原则下的可能分段方式进行详细地介绍。
分段数量优先原则
在分段数量优先原则中，当剩余待分段数据的数据长度较多时，对剩余待分段数据进行分段很可能会获得较多的编码块，不利于降低数据的传输时延。该情况下，发送端设备可不再对剩余待分段数据进行分段，而是额外使用一个最大码长的第一编码块来承载整个剩余待分段数据。该情况下，C个编码块中包含第一编码块但不包含第二编码块，C的取值等于第一编码块的数量C 10的取值，即第一编码块的初始数量加1。反之，当剩余待分段数据的数据长度较短时，即使对剩余待分段数据进行分段也很可能只获得较少的编码块，分段对数据传输时延的影响不大。该情况下，发送端设备可参照预设的第一码率在S-1个非最大码长下的预先设定或者配置的数据长度对剩余待分段数据进行分段，将剩余待分段数据分为L个非最大码长对应的第二编码块。其中，每个非最大码长对应的第二编码块的数量可以为1，也可以为2或者大于2的整数，具体不作限定。如此，通过在剩余待分段数据较少的情况下进行分段，能在分段数量满足传输时延的情况下尽量使用小码长的小编码块承载剩余待分段数据，有效降低编码块中承载的无用比特位的数量。
下面示例性介绍在分段数量优先原则下的几种可能的分段方式：
分段方式1-1
在分段方式1-1中，评判是否进行分段的基准为预设的数据长度阈值，当剩余待分段数据的数据长度大于预设的数据长度阈值时，发送端设备可设置第一编码块的数量为大于第一编码块的初始数量的最小整数(即第一编码块的初始数量加1)，而第二编码块的数量为0，也即是不存在第二编码块。当剩余待分段数据的数据长度不大于预设的数据长度阈值时，发送端设备可设置第一编码块的数量为第一编码块的初始数量，并可参照上述步骤502、步骤503和步骤505中确定最大码长对应的第一编码块的初始数量的计算方式，按照码长由大到小的顺序依次确定出S-1个非最大码长对应的编码块的初始数量，并将非最小码长对应的编码块的初始数量作为非最小码长对应的编码块的数量，将不小于最小码长对应的编码块的初始数量的最小整数作为最小码长对应的编码块的数量，进而将S-1个非最大码长中数量不为0的L个非最大码长对应的编码块的数量作为L种第二编码块的数量。
仍以上述场景二为例，介绍分段方式1-1的具体计算过程：在场景二中，剩余待分段数据的数据长度为304bit，假设预设的数据长度阈值为246bit，则剩余待分段数据的数据长度304bit大于该预设的数据长度阈值246bit，因此发送端设备可直接使用一个最大码长1024bit对应的数据长度为384bit的第一编码块来承载整个剩余待分段数据，也即是说，384bit的第一编码块中存在304bit用于承载剩余待分段数据，而剩下的80bit为无用比特位。
在另一个场景(简称为场景三)中，假设剩余待分段数据为200bit，第一码率为3/8，则参照表2.11(B)所示意的K表可知，在3/8码率下，512bit码长对应的预先设定或者配置的数据长度为128bit，因此512bit码长对应的编码块的数量为：floor(200/128)＝1；更新剩余的待分段数据的数据长度D ls为：200bit-128bit＝72bit，在3/8码率下，256bit码长对应的预先设定或者配置的数据长度为64bit，因此256bit码长对应的编码块的数量为：floor(72/64)＝1；更新剩余的待分段数据的数据长度D ls为：72bit-64bit＝8bit，在3/8码率下，128bit码长对应的预先设定或者配置的数据长度为32bit，因此128bit码长对应的编码块的数量为：floor(8/32)＝0；剩余的待分段数据的数据长度D ls仍为8bit，在3/8码率下，64bit码长(即最小码长)对应的预先设定或者配置的数据长度为16bit，因此64bit码长对应的编码块的数量为：ceil(8/16)＝1。由于非最大码长512bit、256bit、128bit和64bit对应的编码块的数量分别为1、1、0、1，因此共存在如下3种第二编码块：第一种第二编码块的码长为512bit，数量为1，数据长度为128bit，第二种第二编码块的码长为256bit，数量为1，数据长度为64bit，第三种第二编码块的码长为64bit，数量为1，数据长度为16bit，这三个第二编码块的数据长度共计208bit，其中的200bit用于承载剩余待分段数据，剩余的8bit属于无用比特位，后续可进行填充或从数据长度中减去。
分段方式1-2
在分段方式1-2中，评判是否进行分段的基准可为任一码长对应的数量阈值。以最小码长为例，发送端设备可先将剩余待分段数据折算到最小码长对应的编码块中，得到最小码长对应的编码块的预计数量，如果该预计数量大于最小码长对应的数量阈值，则发送端设备设置第一编码块的数量为大于第一编码块的初始数量的最小整数，而第二编码块的数量为0，也即是不存在第二编码块。如果该预计数量不大于最小码长对应的预设的数量阈值，则发送端设备可设置第一编码块的数量为第一编码块的初始数量，并可参照预设的第一码率在S-1个非最大码长下的预先设定或者配置的数据长度和预设的第一码率在最小码 长N S-1下的预先设定或者配置的数据长度之间的比值关系，折算最小码长对应的编码块的预计数量，获得S-1个非最大码长对应的编码块的数量，进而将其中数量不为0的L个非最大码长对应的编码块的数量作为L种第二编码块的数量。
假设K表中规定预设的第一码率在最小码长N S-1下的预先设定或者配置的数据长度为K S-1(即K表中规定最小码长对应的一个编码块的数据长度为K S-1)，则最小码长N S-1对应的编码块的预计数量C S-1'可满足如下公式(5.4)：
C S-1'＝ceil(K ls/K S-1)……(5.4)
其中，ceil()是向上取整函数，即取不小于括号中的数值的最小整数，例如ceil(1.5)即是取不小于1.5的最小整数，其计算结果为2，ceil(2)即是取不小于2的最小整数，其计算结果为2。如此，通过上述公式(5.4)所计算出的最小码长N S-1对应的编码块的预计数量C S-1'，可用于指示承载不少于剩余待分段数据的总数据长度的最小编码块的最小数量，该最小数量能保证将全部剩余待分段数据都包含在内，以避免遗漏待分段数据。
进一步的，考虑到非最大码长N 1～N S-1共有S-1个，而随着剩余待分段数据的数据长度的逐渐变长，剩余待分段数据会按照码长逐渐变大的顺序依次被分到非最大码长N S-1～N 1所对应的编码块，等到被分到非最大码长N 1所对应的编码块后，又会开始按照码长逐渐变大的顺序重复分到非最大码长N S-1到N 1所对应的编码块，也即是每个非最大码长对应的编码块的数量可能会大于1。基于此，一个可能的示例中，可将非最大码长N S-1作为允许分段数量的一个临界点，预先设定或者配置预设的数量阈值为2 S-1-1，通过采用该预设的数量阈值2 S-1-1作为决策是否能进行分段的基准，能尽量确保剩余待分段数据分为每个非最大码长所对应的编码块的数量不大于1。相应的，按照该原则，如果是采用上述分段方式1-1中的方案将预设的数据长度阈值作为分段基准，则预设的数据长度阈值可对应设置为K S-1×(2 S-1-1)。
基于此，当最小码长对应的编码块的预计数量C S-1'大于最小码长对应的数量阈值2 S-1-1时，发送端设备可获得C 0'+1个第一编码块。例如，在上述场景二中，由于剩余待分段数据的数据长度为304bit，3/8码率在最小码长64bit下的预先设定或者配置的数据长度为16，因此最小码长64bit对应的编码块的预计数量为不小于304和16的比值的最小整数，304和16的比值恰好为19，因此最小码长64bit对应的编码块的预计数量即为19。继续参照表2.11所示，K表中共存在5个码长，也即是S的取值为5，因此，当预设的数量阈值设置为2 S-1-1时，预设的数量阈值为：2 4-1＝15，而场景二计算出的最小码长64bit对应的编码块的预计数量19大于该预设的数量阈值15，因此，发送端设备可不再对剩余待分段数据进行分段，而是另外设置一个第一编码块承载整个剩余待分段数据。假设无用比特位放在最后一个第一编码块中，则由于第一编码块的初始数量为2，因此分段后的C个编码块可包括：3个数据长度为384bit的第一编码块，第1个第一编码块中包含360bit的信息比特和24bit的第一校验码，第2个第一编码块中包含360bit的信息比特和24bit的第一校验码，第3个第一编码块中包含280bit的信息比特和24bit的第一校验码，且还包含80bit的无用比特位，后续可进行填充或从数据长度中减去。
反之，当最小码长对应的编码块的预计数量C S-1'不大于最小码长对应的数量阈值2 S-1-1时，根据表1.1所示意的K表中同一码率所在的那行数据可知，针对于非最大码长N 1～N S-1中的任一非最大码长N j(j为小于或等于S-2的正整数)，该非最大码长N j对应的预先设定或者配置的数据长度和最小码长N S-1对应的预先设定或者配置的数据长度的比值刚好等于 该非最大码长N j和最小码长N S-1的比值，换句话说，同样数据长度的数据划分为非最大码长N j对应的编码块所获得的数量和划分为最小码长N S-1对应的编码块所获得的数量的比值等于最小码长N S-1和非最大码长N j的比值。例如，当K表具体表示为表2.11(B)时，非最大码长N 1～N S-1分别为512、256、128、64，最小码长N S-1为64，同一码率下非最大码长512、256、128、64对应的预先设定或者配置的数据长度与最小码长64对应的预先设定或者配置的数据长度的比值分别为：8:1、4:1、2:1、1:1，也即是说，最小码长64对应的8个编码块能折算到非最大码长512对应的1个编码块中，最小码长64对应的4个编码块能折算到非最大码长256对应的1个编码块中，最小码长64对应的2个编码块能折算到非最大码长128对应的1个编码块中，最小码长64对应的1个编码块能折算到非最大码长64对应的1个编码块中。
基于此，发送端设备在确定最小码长N S-1对应的编码块的预计数量C S-1'不大于最小码长对应的数量阈值2 S-1-1时，可按照如下分段方式1-21或分段方式1-22中的任一分段方式对剩余待分段数据进行分段：
分段方式1-21
实施中，发送端设备可按照码长从大到小的顺序依次确定S-1个非最大码长N 1～N S-1中的每个非最大码长对应的编码块的数量：
第一步，S-1个非最大码长N 1～N S-1中的最大的非最大码长N 1对应的编码块的数量C 1可满足如下公式(5.51)：
C 1＝floor(C S-1'/(N 1/N S-1))……(5.51)
其中，上述公式(5.51)是将最小码长N S-1对应的编码块的预计数量尽可能地折算在最大的非最大码长N 1中。示例性的，当最大的非最大码长N 1和最小码长N S-1分别为表2.11(B)所示意的512bit和64bit时，上述公式(5.51)可简化为：C 1＝floor(C S-1'/8)。
第二步，当C 1不为0时，由于最小码长N S-1对应的编码块的预计数量C S-1'中的一部分已折算到非最大码长N 1对应的编码块中，因此，可更新最小码长N S-1对应的编码块的预计数量C S-1'，更新后的预计数量C S-1'满足如下公式(5.52)：
C S-1'＝C S-1'-C 1×(N 1/N S-1)……(5.52)
其中，当最大的非最大码长N 1和最小码长N S-1分别为表2.11(B)所示意的512bit和64bit时，上述公式(5.52)可简化为：C S-1'＝C S-1'-8C 1。
第三步，剩下的S-2个非最大码长N 2～N S-1中的最大的非最大码长N 2对应的编码块的数量C 2可满足如下公式(5.53)：
C 2＝floor(C S-1'/(N 2/N S-1))……(5.53)
其中，上述公式(5.53)是将最小码长N S-1对应的编码块的剩余的预计数量尽可能地折算在剩下的S-2个非最大码长N 2～N S-1中的最大的非最大码长N 2中。当非最大码长N 2和最小码长N S-1分别为表2.11(B)所示意的256bit和64bit时，上述公式(5.53)可简化为：C 2＝floor(C S-1'/4)。
第四步，当C 2不为0时，由于最小码长N S-1对应的编码块的剩余的预计数量C S-1'中的一部分已折算到非最大码长N 2对应的编码块中，因此，进一步更新最小码长N S-1对应的编码块的预计数量C S-1'，更新后的预计数量C S-1'满足如下公式(5.54)：
C S-1'＝C S-1'-C 2×(N 2/N S-1)……(5.54)
其中，当非最大码长N 2和最小码长N S-1分别为表2.11(B)所示意的256bit和64bit 时，上述公式(5.54)可简化为：C S-1'＝C S-1'-4C 2。
不断执行上述过程，直至依次遍历至最小的非最大码长N S-2时，更新后的最小码长N S-1对应的编码块的预计数量C S-1'满足如下公式(5.55)：
C S-1'＝C S-1'-C S-2×(N S-2/N S-1)……(5.55)
其中，当非最大码长N S-2和最小码长N S-1分别为表2.11(B)所示意的128bit和64bit时，上述公式(5.55)可简化为：C S-1'＝C S-1'-2C S-2。
最后一步，由于非最大码长N S-1即为最小码长，因此非最小码长N S-1对应的编码块的数量C S-1可满足如下公式(5.56)：
C S-1＝C S-1'……(5.56)
按照上述计算步骤，发送端设备最终可获得S-1个非最大码长N 1～N S-1各自对应的编码块的数量，任一非最大码长对应的编码块的数量可能为0(即不存在该非最大码长对应的编码块)，也可能不为0，发送端设备可将其中数量不为0的L个非最大码长对应的编码块的数量作为L种第二编码块的数量。
仍以上述场景三为例，由于剩余待分段数据的数据长度为200bit，表2.11(B)所示意出的K表中显示最小码长64bit对应的预先设定或者配置的数据长度为16bit，因此最小码长64bit对应的编码块的预计数量为：ceil(200bit/16bit)＝13。根据该预计数量13，发送端设备可按照码长由大到小的顺序依次执行如下分析：首先，最大的非最大码长512bit和最小码长64bit的比值为8:1，意味着8个最小码长64bit对应的编码块可折算为1个非最大码长512bit对应的编码块，最小码长64bit对应的编码块的预计数量13可折算出1个非最大码长512bit对应的编码块，因此非最大码长512bit对应的编码块的数量为1，折算后剩余的最小码长64bit对应的编码块的预计数量为：13-1×8＝5；其次，非最大码长256bit和最小码长64bit的比值为4:1，意味着4个最小码长64bit对应的编码块可折算为1个非最大码长256bit对应的编码块，而剩余的最小码长64bit对应的编码块的预计数量5可折算出1个非最大码长256bit对应的编码块，因此非最大码长256bit对应的编码块的数量为1，折算后剩余的最小码长64bit对应的编码块的预计数量为：5-1×4＝1；再者，非最大码长128bit和最小码长64bit的比值为2:1，意味着2个最小码长64bit对应的编码块可折算为1个非最大码长128bit对应的编码块，而剩余的最小码长64bit对应的编码块的预计数量1不足以折算出1个非最大码长128bit对应的编码块，因此非最大码长128bit对应的编码块的数量为0(即不存在非最大码长128bit对应的编码块)，由于未进行折算，因此剩余的最小码长64bit对应的编码块的预计数量仍为1；最后，非最大码长64bit对应的编码块的数量等于剩余的最小码长64bit对应的编码块的预计数量1。假设无用比特位放在第一个第二编码块中，则由于非最大码长512bit、256bit、128bit和64bit对应的编码块的数量分别为1、1、0、1，因此C个编码块中共包含如下3种第二编码块：第一种第二编码块的码长为512bit，数量为1，数据长度为128bit，该128bit中的120bit存储的都是信息比特，剩下的8bit属于无用比特位，后续可进行填充或从数据长度中减去；第二种第二编码块的码长为256bit，数量为1，数据长度为64bit，该64bit中的56bit存储的是信息比特，剩下的8bit中存储的是第二校验码的8bit信息；第三种第二编码块的码长为64bit，数量为1，数据长度为16bit，该16bit存储的是第二校验码的剩余的16bit信息。
分段方式1-22
参照表1.1所示意的K表，考虑到S-1个非最大码长N 1～N S-1与最小码长N S-1的比值 关系依次满足2 S-2、2 S-3、……、2 1和2 0，因此，在每个非最大码长对应的第二编码块的数量不大于1的情况下，最小码长N S-1对应的编码块的数量和S-1个非最大码长N 1～N S-1对应的编码块的数量之间的折算关系可以一个S-1位的二进制数据来表示。基于此，发送端设备在获得最小码长N S-1对应的编码块的预计数量C S-1'后，可将C S-1'转换为S-1位的二进制数据，该二进制数据中的由高位到低位的S-1个比特位一一对应码长由大到小的S-1个非最大码长N 1～N S-1，发送端设备可将该二进制数据中取值不为0的L个比特位的取值作为L种第二编码块的数量，L种第二编码块中的每种第二编码块的数据长度为所对应的比特位对应的非最大码长的预先设定或者配置的数据长度。
仍以上述场景三为例，介绍分段方式1-22的具体计算过程：表2.11(B)所示意的K表中共存在4个非最大码长512bit、256bit、128bit和64bit，因此，在获得最小码长64bit对应的编码块的预计数量13后，可将十进制的数值13转化为4位的二进制数据1101(即13＝2 3+2 2+2 0)，二进制数据1101中的4个比特位的取值1、1、0和1分别对应非最大码长512bit对应的编码块的数量、非最大码长256bit对应的编码块的数量、非最大码长128bit对应的编码块的数量和非最大码长64bit对应的编码块的数量。由低位到高位来说，由于取值不为0的比特位为第一位、第二位和第四位，因此待分段数据可分为3种第二编码块，第一种第二编码块的码长为512bit，数量为1，第二种第二编码块的码长为256bit，数量为1，第三种第二编码块的码长为64bit，数量为1。
在上述分段方式1-2中，先将剩余待分段数据折算到最小码长对应的编码块中，获得最小码长对应的编码块的预计数量，再参照各个非最大码长对应的预先设定或者配置的数据长度的比值关系，将最小码长对应的编码块的预计数量折算到各个非最大码长对应的编码块。由于最小码长对应的编码块的数据长度最小，因此向最小码长对应的编码块进行折算能尽量确保分段时产生最少的无用比特位，有效节省后续填充或从数据长度中减去等操作的复杂性，有助于节省空口开销。
分段方式1-3
上述分段方式1-1需要根据剩余待分段数据的数据长度进行实时计算，上述分段方式1-2需要根据最小码长N S-1对应的编码块的预计数量C S-1'进行实时计算，而分段方式1-3给出一种可根据剩余待分段数据的数据长度和/或最小码长N S-1对应的编码块的预计数量C S-1'，通过查询预设的码率、码长、剩余待分段数据的数据长度和/或最小码长对应的编码块的预计数量、以及各个码长对应的编码块的数量的对应关系，直接获得L种第二编码块各自对应数量的方式。其中，预设的码率、码长、剩余待分段数据的数据长度和/或最小码长对应的编码块的预计数量、以及各个码长对应的编码块的数量的对应关系可以以表格、数据库或栈等中的任一形式来表示，具体不作限定。
示例性的，当预设的码率、码长、剩余待分段数据的数据长度和/或最小码长对应的编码块的预计数量、以及各个码长对应的编码块的数量的对应关系以表格形式表示时，表4示出本申请实施例提供的一种预设的码率、码长、剩余待分段数据的数据长度和/或最小码长对应的编码块的预计数量、以及各个码长对应的编码块的数量的对应关系示意表，其中，表4(A)示出的是在1/4码率下各个码长对应的编码块数量的示意表，表4(B)示出的是在3/8码率下各个码长对应的编码块数量的示意表，表4(C)示出的是在1/2码率下各个码长对应的编码块数量的示意表，表4(D)示出的是在5/8码率下各个码长对应的编码块数量的示意表，表4(E)示出的是在3/4码率下各个码长对应的编码块数量的示意表， 表4(F)示出的是在7/8码率下各个码长对应的编码块数量的示意表。
在表4(A)～表4(F)中：K ls为除最大码长的第一编码块包含的信息比特以外的剩余信息比特的数据长度，单位为bit；D ls为剩余待分段数据的数据长度，单位为bit，D ls为剩余信息比特的数据长度K ls和第二校验码的数据长度CRC ls之和，第二校验码的数据长度CRC ls预先设定或者配置为24bit；N为码长，单位为bit；C S-1'为最小码长64bit对应的编码块的预计数量。除这些信息以外，该对应关系表中还可包括如下内容中的一项或多项：
C ls，是指承载剩余待分段数据的编码块的数量。在最小码长64bit对应的编码块的预计数量C S-1'大于预设的数量阈值(在表4(A)～表4(F)中，由于共存在5个码长，因此预设的数量阈值设置为：2 5-1-1＝15)的情况下，由于剩余待分段数据都承载在一个最大码长对应的第一编码块中，因此C ls的取值为1，例如表4(A)自C S-1'大于15开始(即编号13至编号29)，C ls的取值都为1。在预计数量C S-1'不大于预设的数量阈值的情况下，剩余待分段数据承载在C 20个非最大码长对应的第二编码块中，C ls的取值会随着预计数量C S-1'的变化而变化，例如当表4(A)中的C S-1'取6(即编号3)时，C ls的取值为2，但C S-1'取7时(即编号4)，C ls的取值为3。
K Diff，是指在表4(A)～表4(F)所给出的分段方式下，承载剩余待分段数据的编码块的总数据长度和剩余待分段数据的数据长度的比特差值，单位为bit，这些比特差值用于指示所存在的无用比特位的数量。在最小码长64bit对应的编码块的预计数量C S-1'大于预设的数量阈值的情况下，由于剩余待分段数据都承载在一个最大码长对应的第一编码块中，而最大码长对应的第一编码块的数据长度相对较长，因此无用比特位的数量K Diff一般也较大，例如表4(A)自C S-1'大于15开始(即编号13至编号29)，K Diff的取值大都达到了上百比特。在最小码长64bit对应的编码块的预计数量C S-1'不大于预设的数量阈值的情况下，剩余待分段数据承载在一个或多个非最大码长对应的第二编码块中，而非最大码长对应的第二编码块的数据长度相对较短，因此无用比特位的数量K Diff一般也较小，例如在C S-1'不大于15的情况下，表4(A)中的K Diff的取值均为0(即不存在无用比特位)，表4(B)中的K Diff的取值在0和8bit之间循环，表4(C)中的K Diff的取值在0、8bit和16bit之间循环，表4(D)中的K Diff的取值在0、8bit、16bit和24bit之间循环，表4(E)中的K Diff的取值在0、8bit、16bit、24bit和32bit之间循环，而表4(F)中的K Diff的取值在0、8bit、16bit、24bit、32bit和40bit之间循环，可见，针对于表4(A)至表4(F)中示出的任一码率，最大的K Diff均不超过40bit，相比于采用第一编码块承载时的上百比特来说是非常小的。
需要指出的是，表4(A)～表4(F)所示意的对应关系表中还可包含一些其它信息，例如信息比特的总数据长度，或第一编码块的数量等，具体不作限定。

为便于理解，仍以上述场景二和场景三为例，介绍分段方式1-3的具体计算过程：
在场景二中，剩余待分段数据的数据长度D ls为304bit，第一码率为3/8，最小码长64bit对应的编码块的预计数量为19，发送端设备可根据这些信息直接查询预设的码率、码长、剩余待分段数据的数据长度和/或最小码长对应的编码块的预计数量、以及各个码长对应的编码块的数量的对应关系，并获得如下信息(例如，当对应关系以表4(A)至表4(F)中的对应关系表的方式承载时，可查询表4(B)所示意的对应关系表，获得编号为35的那行数据)：1024bit码长对应的编码块的数量为1，而512bit码长、256bit码长、128bit码长和64bit码长对应的编码块的数量均为0(即不存在512bit码长、256bit码长、128bit码长和64bit码长对应的编码块)。因此，剩余待分段数据都承载在一个1024bit码长的第一编码块中，该第一编码块的数据长度为384bit，其中的304bit用于承载剩余待分段数据，剩下的80bit为无用比特位。
在场景三中，剩余待分段数据的数据长度D ls为200bit，第一码率为3/8，最小码长64bit对应的编码块的预计数量为13，数据分段装置可根据这些信息查询预设的码率、码长、剩 余待分段数据的数据长度和/或最小码长对应的编码块的预计数量、以及各个码长对应的编码块的数量的对应关系，并获得如下信息(例如，当对应关系以表4(A)至表4(F)中的对应关系表的方式承载时，可查询表4(B)所示意的对应关系表，获得编号为22的那行数据)：1024bit码长对应的编码块的数量为0(即不存在1024bit码长对应的编码块)，512bit码长对应的编码块的数量为1，256bit码长对应的编码块的数量为1，128bit码长对应的编码块的数量为0(即不存在128bit码长对应的编码块)，64bit码长对应的编码块的数量为1。因此，剩余待分段数据可承载在一个512bit码长的第二编码块、1个256bit码长的第二编码块和1个64bit码长的第二编码块中，且这三个第二编码块中除了承载剩余待分段数据外，还存在8bit的无用比特位。
需要指出的是，在预设的码率、码长、剩余待分段数据的数据长度和/或最小码长对应的编码块的预计数量、以及各个码长对应的编码块的数量的对应关系，最大码长1024bit对应的编码块的数量是指用于承载剩余待分段数据D ls的第一编码块的数量，而并是指承载信息比特的第一编码块的数量。例如，以表4(A)为例，虽然编号1至编号9中最大码长1024bit对应的编码块的数量都为0，但这只是限定剩余待分段数据D ls不承载在第一编码块中，而除剩余待分段数据D ls中所包含的剩余信息比特K ls以外的信息比特承载在第一编码块的数量可以为0，也可以为1个、2个或2个以上，具体不作限定。
在上述分段数量优先原则中，先将信息比特尽可能多地承载在最大码长的第一编码块中，再根据剩余信息比特的多少来执行不同的分段操作，在剩余信息比特较多时不再进行分段，而是另外使用一个最大码长的第一编码块来承载整个剩余信息比特，能通过避免过多分出短编码块来保持较低的数据传输时延，而在剩余信息比特较少时采用小码长对应的短编码块进行分段，还能在数据传输时延本身较低的情况下通过更精细地分段来减少编码块中包含的无用比特位的数量，有效降低数据传输所产生的空口开销。更进一步的，通过在剩余信息比特较少时使用小码长对应的第二编码块来承载剩余信息比特，而第二编码块的数据长度相比于最大码长的第一编码块来说更小，因此即使是需要重传剩余信息比特，也能重传数据长度更小的第二编码块而不重传第一编码块，进一步降低重传的数据量和重传时延。
比特位数量优先原则
在比特位数量优先原则中，考虑到最大码长对应的第一编码块的数据长度大于非最大码长对应的第二编码块的数据长度，因此，如果使用最大码长的第一编码块来承载整个待分段数据，则很可能会使该第一编码块中包含较多的无用比特位，无形中增大了传输的数据量，不利于降低数据传输的空口损耗。基于此，发送端设备在获得第一编码块的初始数量和剩余待分段数据的数据长度后，可直接将第一编码块的初始数量作为第一编码块的数量，并采用非最大码长对剩余待分段数据进行分段，而不再关注剩余待分段数据的数据长度是多还是少。该原则在各种场景下都能尽量使用小码长对应的短编码块承载剩余待分段数据，有助于降低分段后的编码块中包含的无用比特位的数量，进而降低数据传输所产生的空口损耗。
下面示例性地介绍在比特位数量优先原则下的几种可能的分段方式：
分段方式2-1
分段方式2-1可利用剩余待分段数据的数据长度进行分段。在实施中，发送端设备可将第一编码块的初始数量作为第一编码块的数量，并可参照上述步骤502、步骤503和步 骤505中确定最大码长对应的第一编码块的初始数量的计算方式，按照码长由大到小的顺序依次确定出S-1个非最大码长对应的编码块的初始数量，并将非最小码长对应的编码块的初始数量作为非最小码长对应的编码块的数量，将不小于最小码长对应的编码块的初始数量的最小整数作为最小码长对应的编码块的数量，进而将S-1个非最大码长中数量不为0的L个非最大码长对应的编码块的数量作为L种第二编码块的数量。
仍以上述场景二为例，介绍分段方式2-1的具体计算过程：在场景二中，剩余待分段数据的数据长度为304bit，参照表2.11(B)所示意的K表可知，在3/8码率下，512bit码长对应的预先设定或者配置的数据长度为128bit，因此512bit码长对应的编码块的数量为：floor(304/128)＝2；更新剩余的待分段数据的数据长度D ls为：304bit-2×128bit＝48bit，在3/8码率下，256bit码长对应的预先设定或者配置的数据长度为64bit，因此256bit码长对应的编码块的数量为：floor(48/64)＝0；剩余的待分段数据的数据长度D ls仍为48bit，在3/8码率下，128bit码长对应的预先设定或者配置的数据长度为32bit，因此128bit码长对应的编码块的数量为：floor(48/32)＝1；更新剩余的待分段数据的数据长度D ls为：48bit-32bit＝16bit，在3/8码率下，最小码长64bit对应的预先设定或者配置的数据长度为16bit，因此最小码长64bit对应的编码块的数量设置为：ceil(16/16)＝1。由于非最大码长512bit、256bit、128bit和64bit对应的编码块的数量分别为2、0、1、1，因此共存在如下3种第二编码块：第一种第二编码块的码长为512bit，数量为2，且每个第二编码块的数据长度为128bit，2个第二编码块的128bit中存储的都是信息比特；第二种第二编码块的码长为128bit，数量为1，数据长度为32bit，该32bit中的24bit存储的是信息比特，剩下的8bit存储的是第二校验码的8bit信息；第三种第二编码块的码长为64bit，数量为1，数据长度为16bit，该16bit中存储的第二校验码的剩余的16bit信息。
分段方式2-2
分段方式2-2可利用最小码长对应的编码块的预计数量C S-1'进行分段。在实施中，发送端设备可将第一编码块的初始数量作为第一编码块的数量，并按照上述分段方式1-21中的公式(5.51)至公式(5.56)依次获得S-1个非最大码长N 1～N S-1所的编码块的数量，并从中选择出编码块的数量不为0的L个非最大码长，将该L个非最大码长对应的编码块的数量作为L种第二编码块的数量。
仍以上述场景二为例，介绍分段方式2-2的具体计算过程：在场景二中，剩余待分段数据的数据长度为304bit，将其折算到在3/8码率下的最小码长64bit对应的编码块中，获得最小码长64bit对应的编码块的预计数量为19。根据该预计数量19，发送端设备可按照码长由大到小的顺序依次执行如下分析：首先，最大的非最大码长512bit和最小码长64bit的比值为8:1，最小码长64bit对应的编码块的预计数量19可折算出2个非最大码长512bit对应的编码块，因此非最大码长512bit对应的编码块的数量为2，折算后剩余的最小码长64bit对应的编码块的预计数量为：19-2×8＝3；其次，非最大码长256bit和最小码长64bit的比值为4:1，而剩余的最小码长64bit对应的编码块的预计数量3不足以折算出1个非最大码长256bit对应的编码块，因此非最大码长256bit对应的编码块的数量为0(即不存在非最大码长256bit对应的编码块)，由于未进行折算，因此剩余的最小码长64bit对应的编码块的预计数量仍为3；再者，非最大码长128bit和最小码长64bit的比值为2:1，剩余的最小码长64bit对应的编码块的预计数量3可折算出1个非最大码长128bit对应的编码块，因此非最大码长128bit对应的编码块的数量为1，折算后剩余的最小码长64bit对应的编码 块的预计数量更新为：3-2×1＝1；最后，非最大码长64bit对应的编码块的数量等于剩余的最小码长64bit对应的编码块的预计数量1。由于非最大码长512bit、256bit、128bit和64bit对应的编码块的数量分别为2、0、1、1，因此共存在如下3种第二编码块：第一种第二编码块的码长为512bit，数量为2，且每个第二编码块的数据长度为128bit；第二种第二编码块的码长为128bit，数量为1，数据长度为32bit；第三种第二编码块的码长为64bit，数量为1，数据长度为16bit。
分段方式2-3
上述分段方式2-1需要根据剩余待分段数据的数据长度进行实时计算，上述分段方式2-2需要基于最小码长N S-1对应的编码块的预计数量C S-1'进行实时计算，而分段方式2-3给出一种可根据剩余待分段数据的数据长度和/或最小码长N S-1对应的编码块的预计数量C S-1'，通过查询预设的码率、码长、剩余待分段数据的数据长度和/或最小码长对应的编码块的预计数量、以及各个码长对应的编码块的数量的对应关系，直接获得L种第二编码块各自对应数量的方式。其中，预设的码率、码长、剩余待分段数据的数据长度和/或最小码长对应的编码块的预计数量、以及各个码长对应的编码块的数量的对应关系可以以表格、数据库或栈等中的任一形式来表示，具体不作限定。
示例性的，当预设的码率、码长、剩余待分段数据的数据长度和/或最小码长对应的编码块的预计数量、以及各个码长对应的编码块的数量的对应关系以对应关系表的形式表示时，表5示出本申请实施例提供的一种预设的码率、码长、剩余待分段数据的数据长度和/或最小码长对应的编码块的预计数量、以及各个码长对应的编码块的数量的对应关系示意表，其中，表5(A)示出的是在1/4码率下各个码长对应的编码块数量的示意表，表5(B)示出的是在3/8码率下各个码长对应的编码块数量的示意表，表5(C)示出的是在1/2码率下各个码长对应的编码块数量的示意表，表5(D)示出的是在5/8码率下各个码长对应的编码块数量的示意表，表5(E)示出的是在3/4码率下各个码长对应的编码块数量的示意表，表5(F)示出的是在7/8码率下各个码长对应的编码块数量的示意表。其中，表5(A)～表5(F)中的各项信息(例如K ls、D ls、N、C S-1'、C ls和K Diff)与上述表4(A)～表4(F)一致，此处不再重复介绍。

仍以上述场景二为例，介绍分段方式2-3的具体计算过程：在场景二中，剩余待分段数据的数据长度D ls为304bit，第一码率为3/8，最小码长64bit对应的编码块的预计数量为19，发送端设备可根据这些信息查询预设的码率、码长、剩余待分段数据的数据长度和/或最小码长对应的编码块的预计数量、以及各个码长对应的编码块的数量的对应关系，并获得如下信息(例如，当对应关系以表5(A)至表5(F)中的对应关系表的方式承载时，可查询表5(B)所示意的对应关系表，获得编号为35的那行数据)：1024bit码长对应的编码块的数量为0(即不存在1024bit码长对应的编码块)，512bit码长对应的编码块的数量为2，256bit码长对应的编码块的数量为0(即不存在256bit码长对应的编码块)，128bit码长对应的编码块的数量为1，64bit码长对应的编码块的数量为1。因此，剩余待分段数据可承载在2个512bit码长的第二编码块、1个128bit码长的第二编码块和1个64bit码长的第二编码块中，且不存在无用比特位。
对比分段数量优先原则和比特位数量优先原则可知，针对于同样的场景二，分段数量优先原则会另外设置一个大码长的长的第一编码块来承载整个剩余待分段数据，以通过减少短的第二编码块的分段数量来降低传输时延，而比特位数量优先原则会设置4个小码长的短的第二编码块来一起承载剩余待分段数据，以通过减少无用比特位的数量来降低空口损耗。在实际操作中，发送端设备可固定设置这两种原则中的其中一个，也可同时设置这两种原则，并根据用户输入的指示灵活启用适用于当前场景的原则，以满足不同场景下的不同需求。
步骤507，发送端设备按照第一编码块的数量和第二编码块的数量分段信息比特，并对分段后的信息比特附加第一校验码/第二校验码，获得C个编码块。
一个示例中(简称为示例一)，假设使用3个最大码长1024bit对应的数据长度为384bit的第一编码块来承载1000bit的信息比特，则发送端设备可先按照顺序将1000bit的信息比特分为360bit、360bit和280bit，针对于第一个360bit生成一个24bit的第一校验码并附加在第一个360bit后获得第一个第一编码块，针对于第二个360bit生成一个24bit的第一校验码并附加在第二个360bit后获得第二个第一编码块，针对于280bit生成一个24bit的第一校验码并附加在280bit后获得第三个第一编码块。
另一个示例中(简称为示例二)，假设使用1个最大码长1024bit对应的数据长度为384bit的第一编码块、1个非最大码长512bit对应的数据长度为128bit的第二编码块、1个非最大码长216bit对应的数据长度为64bit的第二编码块、和1个非最大码长64bit对应的数据长度为16bit的第二编码块来共同承载536bit的信息比特，则发送端设备可先按照顺序将536bit的信息比特分为360bit、128bit和48bit，针对于360bit生成一个24bit的第一校验码并附加在第一个360bit后获得第一编码块，将128bit作为第一个第二编码块，针对于128bit和48bit生成一个24bit的第二校验码，将24bit的第二校验码中的16bit附加在48bit后获得第二个第二编码块，剩余的8bit第二校验码构成第三个第二编码块。
步骤508，发送端设备使用极化码编码C个编码块，获得C个编码块编码后的码字。
示例性的，发送端设备在获得C个编码块之后且编码C个编码块之前，还可以根据C个编码块的数据长度、信息比特的总数据长度、第一校验码的数据长度和/或第二校验码的数据长度，确定C个编码块中存在的无用比特位的数据长度K Diff，并根据无用比特位的数据长度K Diff调整C个编码块。其中，无用比特位的数据长度K Diff为C个编码块的数据长度和有效数据的数据长度之差，有效数据包括编码数据、第一校验码和/第二校验码。下面分别基于几种可能的情况，介绍如何确定无用比特位的数据长度K Diff以及如何调整C个编码块：
情况一，C个编码块中存在C 10个第一编码块但不存在第二编码块。
该情况下，C个编码块的数据长度为C 10个第一编码块的数据长度，而有效数据的数据长度为信息比特的总数据长度和C 10个第一校验码的数据长度之和。假设一个第一编码块的数据长度为K 0，信息比特的总数据长度为K input，一个第一校验码的数据长度为CRC 0，则无用比特位的数据长度K Diff可满足如下公式(5.71)：
K Diff＝C 10×K 0-K input-C 10×CRC 0……(5.71)
在调整时，由于C个编码块中存在C 10个第一编码块但不存在第二编码块，因此，发送端设备可只调整C 10个第一编码块，例如在C 10个第一编码块的一个或多个第一编码块中填充共计K Diff的预设比特序列(如全0比特序列、全1比特序列、字符比特序列、或按照某种规则生成的比特序列等)，或减去共计K Diff的比特位。示例性的，在不存在第二编码块的情况下，由于上述流程只在传输性能有限原则下会额外添加一个第一编码块来承载数据长度较长的剩余待分段数据，因此无用比特位的数据长度K Diff必然小于一个第一编码块的数据长度。因此，为便于管理，发送端设备可在最后一个第一编码块中填充K Diff的预设比特序列或减去K Diff的比特位，例如在最后一个第一编码块的信息比特之前填充K Diff的预设比特序列，如此，由于位于编码块中后方位置的比特可靠性大概率比位于编码块中前方位置的比特可靠性高，因此通过将无用比特信息填充在第一编码块中的前方位置，有 助于将有效信息放在第一编码块中可靠性高的概率比较大的后方位置，有效提升传输有效信息的可靠性；又如在最后一个第一编码块的信息比特和第一校验码之间填充K Diff的预设比特序列，以便使第一校验码也能包含对K Diff的预设比特序列的校验信息，进一步提高数据校验和传输的安全性；再如在最后一个第一编码块的第一校验码之后填充K Diff的预设比特序列，以便使第一校验码不包含无用比特信息对应的校验信息，有效节省校验操作；或者也可以将最后一个第一编码块的数据长度(该数据长度即为根据S个码长、T个码率和S×T个数据长度的对应关系确定出来的预先设定或者配置的数据长度)减去K Diff，以便在编码最后一个第一编码块时对有效数据进行编码而不再对K Diff的无用比特位进行编码。应理解，上述给出的几种填充方式只是一些可能的示例，在实际操作中，还可以在其它位置进行填充，例如也可以在其它任一个第一编码块的信息比特之前、或信息比特和第一校验码之间、或第一校验码之后填充K Diff的预设比特序列，或者也可以将K Diff的预设比特序列分散填充在多个第一编码块中，且每个第一编码块中填充的位置不作限定，等等，此处不再一一列举。
举例来说，在上述示例一中，3个第一编码块的数据长度之和为：3×384bit＝1152bit，而内部承载的有用信息的数据长度之和为：1000bit+3×24bit＝1072bit，3个第一编码块中包含的无用比特位的数据长度为：1152bit-1072bit＝80bit。基于此，一种可能的方式中，发送端设备可在最后一个第一编码块的信息比特前填充80bit的全0序列，使得最后一个第一编码块由依次拼接的80bit的全0序列、280bit信息比特和24bit的第一校验码构成。
情况二，C个编码块中同时存在C 10个第一编码块和C 20个第二编码块。
该情况下，C个编码块的数据长度为C 10个第一编码块的数据长度和C 20个第二编码块的数据长度之和，而有效数据的数据长度为信息比特的总数据长度、C 10个第一校验码的数据长度和一个第二校验码的数据长度之和。假设一个第一编码块的数据长度为K 0，信息比特的总数据长度为K input，一个第一校验码的数据长度为CRC 0，一个第二校验码的数据长度为CRC ls，码长N 1、码长N 2、……、码长N S-1对应的第二编码块的数量分别为C 1、C 2、……、C S-1，则无用比特位的数据长度K Diff可满足如下公式(5.72)：
K Diff＝C 10×K 0+C 1×K 1+C 2×K 2+……+C S-1×K S-1-K input-C 10×CRC 0-CRC ls……(5.72)
在调整时，由于C个编码块中同时存在C 10个第一编码块和C 20个第二编码块，因此，发送端设备可调整C 10个第一编码块中的一个或多个第一编码块，和/或，C 20个第二编码块中的一个或多个第二编码块。例如在C 10个第一编码块的一个或多个第一编码块和/或C 20个第二编码块的一个或多个第二编码块中共填充K Diff的预设比特序列，或减去K Diff的比特位。示例性的，为使最大码长的第一编码块能尽可能多地携带信息比特，发送端设备可在C 20个第二编码块中填充K Diff的预设比特序列或减去K Diff的比特位，例如在C 20个第二编码块的信息比特之前填充K Diff的预设比特序列，以便将无用比特信息填充在第一个第二编码块可靠性较低的最前方位置，以及将有效信息放在第一个第二编码块可靠性较高的后方位置，有效提升传输有效信息的可靠性；又如在C 20个第二编码块的信息比特和第二校验码之间填充K Diff的预设比特序列，以便使第二校验码也能包含对K Diff的预设比特序列的校验信息，进一步加强管理和校验；再如在C 20个第二编码块的第二校验码之后填充K Diff的预设比特序列，以便使第二校验码中不包含无用比特信息对应的校验信息，有效节省校验操作；或者在最后一个第二编码块的末端减去K Diff的比特位(在存在第二编码块的情况下，由于上述流程只在将剩余待分段数据折算到最小码长对应的编码块以获得预计数量时会 执行向上取整的操作，因此无用比特位的数据长度K Diff必然小于一个最小码长的编码块的数据长度，也即小于最后一个第二编码块的数据长度)。应理解，上述给出的几种填充方式只是一些可能的示例，在实际操作中，还可以在其它位置进行填充，例如也可以在其它任一个第二编码块的信息比特之前、或信息比特之后、或第二校验码之前、或第二校验码之后填充K Diff的预设比特序列，或者也可以将K Diff的预设比特序列分散填充在多个第二编码块中，且每个第二编码块中填充的位置不作限定，等等，此处不再一一列举。
举例来说，在上述示例二中，1个最大码长1024bit对应的第一编码块、1个非最大码长512bit对应的第二编码块、1个非最大码长216bit对应的第二编码块和1个非最大码长64bit对应的第二编码块的数据长度之和为：384bit+128bit+64bit+16bit＝592bit，而内部承载的有用信息的数据长度之和为：536bit+24bit+24bit＝584bit，第一编码块和3个第二编码块中包含的无用比特位的数据长度为：592bit-584bit＝8bit。基于此，一种可能的方式中，发送端设备可在第一个第二编码块的信息比特之前填充8bit的全0序列，使得第一个第二编码块由依次拼接的8bit的全0序列和504bit的信息比特构成。
情况三，C个编码块中存在C 20个第二编码块但不存在第一编码块。
该情况下，C个编码块的数据长度为C 20个第二编码块的数据长度，而有效数据的数据长度为信息比特的总数据长度和一个第二校验码的数据长度之和。假设信息比特的总数据长度为K input，一个第二校验码的数据长度为CRC ls，码长N 1、码长N 2、……、码长N S-1对应的第二编码块的数量分别为C 1、C 2、……、C S-1，则无用比特位的数据长度K Diff可满足如下公式(5.73)：
K Diff＝C 1×K 1+C 2×K 2+……+C S-1×K S-1-K input-CRC ls……(5.73)
在调整时，由于C个编码块中存在C 20个第二编码块但不存在第一编码块，因此，发送端设备可调整C 20个第二编码块中的一个或多个第二编码块，例如在C 20个第二编码块的信息比特之前填充K Diff的预设比特序列，又如在C 20个第二编码块的第二校验码之后填充K Diff的预设比特序列，再如在C 20个第二编码块的信息比特和第二校验码之间填充K Diff的预设比特序列等，或者在最后一个第二编码块的数据长度中减去K Diff的比特位等，具体不作限定。
需要指出的是，上述情况一至情况三只是示例性的介绍如何通过计算方式确定K Diff，这只是一种可选地实施方式。另一种可选地实施方式中，当采用上述分段方式1-3或分段方式2-3中的查询对应关系的方式获得分段数量时，还可以预先在对应关系中设定或者配置各种情况所对应的K Diff，并在查询分段数量的过程中同步查询所对应的K Diff，以节省计算流程，有效提高数据分段的效率，例如当对应关系以表4(A)～表4(F)或表5(A)～表5(F)中所示意的表格形式来表示时，发送端设备可查询K Diff所在的那列数据，直接获得所对应场景下的K Diff的取值。
另外，在上述内容中，在某一编码块的数据长度中减去无用比特位，相当于降低了该编码块的数据长度，例如参照表2.11(B)所示，3/8码率在512bit码长下的一个编码块的数据长度原本为128bit，但减去28bit的无用比特位后，使得实际的数据长度变为100bit。换句话说，在3/8的码率下，原本传输一个编码块可以传输128bit的信息，但减去无用比特位后传输一个编码块只能传输100bit的信息，相当于降低了数据的实际码率。当然，该实际码率只是实际传输过程中的真实码率，其原本配置的3/8码率仍然保持不变，仍不需要进行速率匹配。
步骤509，发送端设备将承载C个编码块编码后的码字的消息发送给接收端设备。
步骤510，接收端设备根据信息比特的总数据长度和预设的第一码率，确定第一编码块的数量和各个非最大码长对应的第二编码块的数量。
在上述步骤510中，接收端设备所执行的操作与发送端设备所执行的操作相对应，接收端设备确定第一编码块的数量和各个非最大码长对应的第二编码块的数量的具体实现过程，可直接参照上述发送端设备侧的步骤502至步骤506，此处不再重复赘述。
步骤511，接收端设备根据第一编码块的数量和各个非最大码长对应的第二编码块的数量，从承载C个编码块编码后的码字的消息中获得C个编码块编码后的码字。
在上述步骤511中，接收端设备可以按照发送端设备拼接C个编码块编码后的码字的顺序，对消息中承载C个编码块编码后的码字的序列进行分段，获得每个编码块编码后的码字。其中，发送端设备拼接C个编码块编码后的码字的顺序可以预先设定或者配置给接收端设备，或者由发送端设备发送给接收端设备。一种可能的示例中，假设发送端设备按照第一编码块1(数据长度为384bit，码长为1024bit)、第一编码块2(数据长度为384bit，码长为1024bit)、第二编码块1(数据长度为64bit，码长为256bit)的顺序拼接得到序列，则接收端设备在根据与发送端相同的分段原则确定出序列中包含两个码长为1024bit的第一编码块对应的码字和一个码长为256bit的第二编码块对应的码字后，可以按照上述拼接顺序，先从序列的起始位置获得码长为1024bit的码字作为第一个第一编码块(即第一编码块1)对应的码字，再从第一个第一编码块对应的码字的末端位置的下一个bit开始获得码长为1024bit的码字作为第二个第一编码块(即第一编码块2)对应的码字，再从第二个第一编码块对应的码字的末端位置的下一个bit开始，获得码长为256bit的码字作为第二编码块(即第二编码块1)对应的码字。当然，也可以是反向获取的，例如先从序列的末端位置开始反向获得码长为256bit的码字作为第二编码块(即第二编码块1)对应的码字，再从第一个第二编码块对应的码字的起始位置的上一个bit开始反向获得码长为1024bit的码字作为第二个第一编码块(即第一编码块2)对应的码字，再从第二个第一编码块对应的码字的起始位置的上一个bit开始反向获得码长为1024bit的码字作为第一个第一编码块(即第一编码块1)对应的码字。当然，还可以是通过其它方式获得的，例如通过一次操作同时获得三个编码块，或者先获得第二个第一编码块，再获得第一个第一编码块，最后获得第一个第二编码块等，具体不作限定。
步骤512，接收端设备解码C个编码块编码后的码字，获得C个编码块中包含的信息比特和第一校验码/第二校验码，并校验C个编码块中包含的信息比特和第一校验码/第二校验码。
在上述步骤512中，接收端设备在按照与发送端设备相同的分段原则确定分段结果时，还能同步获得每个编码块中包含的信息比特的数据长度、校验码的数据长度、和/或无用比特位的数据长度，如此，接收端设备在解码得到每个编码块后，可以基于这些信息获得每个编码块中包含的信息比特和/或校验码。其中，如果是按照图4中(C)示出的分段原则，则接收端设备可以从每个第一编码块中获得一个第一校验码，且从全部的第二编码块中获得一个第二校验码，接收端设备还可以根据每个第一编码块中的第一校验码对应的生成多项式校验每个第一编码块，以及根据全部的第二编码块中包含的第二校验码对应的生成多项式校验全部的第二编码块。
示例性的，当编码块中包含无用比特位时，一种可能的实现方式中，如果是通过在编 码块的信息比特之前填充预设数据的方式来调节编码块，则校验码会附加在编码块中包含的预设数据和信息比特之后，该情况下，校验码是针对于编码块中包含的预设数据和信息比特生成的，因此，接收端设备在解码获得编码块后，可以直接使用校验码对应的生成多项式和编码块中包含的预设数据、信息比特和校验码相除，在余数为0时保存编码块中包含的信息比特，在余数不为0时进行重传。另一种可能的实现方式中，如果是通过在编码块的末端填充预设数据的方式来调节编码块，则校验码会附加在编码块中包含的信息比特和预设数据之间，该情况下，校验码是针对于编码块中包含的信息比特生成的，而并未包含对预设数据的校验信息，因此，接收端设备在解码获得编码块后，可以先从编码块中删除填充在末端的预设数据(其中，预设数据的数量可在按照分段原则确定分段结果时同步获取)，使得编码块中只剩余信息比特和校验码，再使用校验码对应的生成多项式和编码块中包含的信息比特和校验码相除，在余数为0时保存编码块中包含的信息比特，在余数不为0时进行重传。再一种可能的实现方式中，如果是通过在编码块中包含的信息比特后方填充预设数据的方式来调节编码块，则校验码会附加在编码块中填充的信息比特和预设数据的后方，该情况下，校验码是针对于编码块中包含的信息比特和预设数据一起生成的，因此，接收端设备在解码获得编码块后，可以直接使用校验码对应的生成多项式和编码块中包含的信息比特、预设数据和校验码相除，在余数为0时保存编码块中包含的信息比特，在余数不为0时进行重传。
在上述实施例二中，通过在每个最大码长的第一编码块的末端附加一个第一校验码，且在全部小码长的第二编码块的末端附加一个第二校验码，而未在每个第二编码块的末端附加一个第二校验码，不仅能节省传输数据量和编码复杂性，还能在重传时根据校验码的校验结果决定重传哪部分校验码所对应的编码块，有效降低重传的数据量和重传时延，以及提高重传效率，有助于同步兼顾降低功耗和重传时延的双重效果。且，通过设置分段数量优先原则和比特位数量优先原则所对应的分段方式，还能根据实际需求选择合适的分段原则，例如在更注重传输时延的场景下选择分段数量优先原则，以便通过减少短编码块的分段数量以降低传输时延，又如在更注重空口损耗的场景下选择比特位数量优先原则，以便通过短编码块的精细分段以降低无用比特位的数量，降低空口损耗，有效提高数据处理方法对各类编码场景的适应能力。
需要指出的是，上述实施例二中的各个示例都是以对应关系一中的第一降阶阈值设置为1/8的场景为例进行介绍的，针对于对应关系一中的第一降阶阈值设置为1/16或其它值的场景，以及针对于对应关系二中的第二降阶阈值设置为任一值的场景，都可参照上述内容直接实现，本申请实施例对此不再一一重复赘述。
