Description

一种数据处理方法和装置 技术领域
本申请涉及通信技术领域，尤其涉及一种数据处理方法和装置。
背景技术
分段编码技术是指将整个数据分成若干段分别进行编码的编码技术，这种技术在无线通信场景中广泛应用。目前的分段方式主要包括极化码(polar code)的分段方式和低密度奇偶校验(low density parity check，LDPC)的分段方式。其中，polar码的分段方法是根据净荷大小确定分段数量，或者根据净荷大小和物理资源大小共同确定分段数量。LDPC的分段方式主要是根据码长和码率来确定分段数量。然而，目前的分段方式均没有考虑接收装置(例如终端设备)的能力信息(比如译码能力)和关键绩效指标(key performance indicator，KPI)，从而导致接收装置执行译码的性能较低。
鉴于上述问题，目前亟需提出一种数据处理方法，可以根据接收装置的译码能力信息来对待编码数据进行分段处理，以有效地确保后续接收装置的译码性能。
发明内容
本申请提出了一种数据处理方法和装置，可以根据接收装置的译码能力信息来对待编码的信息比特进行分段处理，以有效地确保接收装置的译码性能。
第一方面，本申请提供一种数据处理方法，该方法可由第一通信装置实施。其中，第一通信装置可以为但不限定于终端设备、网络设备、终端设备中的组件或网络设备中的组件。本申请中的组件例如可包括芯片、芯片系统、处理器、收发器、处理单元或收发单元中的至少一种。以执行主体是第一通信装置为例，该方法的步骤可以包括：获取第二通信装置的译码能力信息；根据该第二通信装置的译码能力信息对第一信息比特进行分段处理，得到分段后的信息比特；再对该分段后的信息比特进行编码处理，得到码字比特；输出该码字比特。
在本申请方案中，第一通信装置可根据第二通信装置的译码能力信息对第一信息比特进行分段处理，以保证该第二通信装置接收到分段的码字比特之后执行译码的性能。
在本申请实施例中，该第一通信装置获取该第二通信装置的译码能力信息，可以通过但不限于以下几种方式实现：
方式一：获取第一信息，该第一信息用于指示该第二通信装置的译码能力信息。
方式二：获取该第二通信装置的能力信息，该第二通信装置的能力信息中的第一字段用于指示该第二通信装置的译码能力信息。
方式三：获取该第二通信装置的类型信息，该第二通信装置的类型信息中包括该第二通信装置的译码能力信息。
在一种可能的实施方式中，上述的第一信息或第二通信装置的能力信息或第二通信装置的类型信息可以来自该第二通信装置。
通过上述几种方式，第一通信装置可以灵活且有效地获得第二通信装置的译码能力信息。
一种可能的实施方式中，该第二通信装置的译码能力信息为该第二通信装置支持译码的码字的最大长度Nmax。
通过该实施方式，将第二通信装置支持译码的码字的最大长度Nmax作为该第二通信装置的译码能力信息，以用于分段处理中，可以有效保障后续该第二通信装置译码的性能。
另一种可能的实施方式中，该第二通信装置的译码能力信息为该第二通信装置支持译码的码字的最低码率Rmin；Rmin＝A/Nmax；其中A为该第一信息比特的比特数，Nmax为该第二通信装置支持译码的码字的最大长度。
通过该实施方式，第一通信装置可以通过获得第二通信装置支持译码的码字的最低码率Rmin，进而也可以有效计算出该第二通信装置支持译码的码字的最大长度Nmax。
一种可能的实施方式中，该第一通信装置根据该第二通信装置的译码能力信息对第一信息比特进行分段处理，得到分段后的信息比特，可以包括：根据码率、该第一信息比特以及该第二通信装置支持译码的码字的最大长度Nmax进行分段处理。
在本申请实施例中，该码率是指当前编码的码率。
通过该实施方式，第一通信装置可根据当前编码码率和第二通信装置支持译码的码字的最大长度对第一信息比特进行分段处理，以保障后续该第二通信装置执行译码的性能。
一种可能的实施方式中，该第一通信装置根据码率、该第一信息比特以及该第二通信装置支持译码的码字的最大长度Nmax进行分段处理，包括：根据每段级联的循环冗余校验CRC的比特数L、该码率、该Nmax、以及该第一信息比特的比特数，确定初始分段数值C′；L为预设的大于或等于0的整数，C′为大于1或者等于1的整数；对应于该码率大于或等于预设码率，确定分段数量等于C′；对应于该码率小于该预设码率，确定分段数量等于C1，C1为小于或者等于C′的正整数。
在本申请实施例中，该初始分段数值C′可以满足下式：
其中，Kcb为分段后的每段信息比特数的最大值，R为该码率；A为该第一信息比特的比特数，为向上取整符号；y为大于1或者等于1的整数。
通过该实施方式，先根据每段级联的CRC的比特数L、码率、Nmax以及该第一信息比特的比特数计算出初始分段数值；若当前的码率较大时(即大于或等于预设码率)，将分段数量设置为该初始分段数值，可保证第二通信装置译码的性能；若当前的码率较小时(即小于预设码率)，将分段数量设置得比初始分段数值小，这样分段后的每段信息比特的大小增大，码率可以得到提高，以避免低码率下导致译码性能较低的问题。
一种可能的实施方式中，该第一通信装置对该分段后的信息比特进行编码处理，得到码字比特，包括：在分段后的每段信息比特的尾部级联一段比特数为L的CRC，得到每段级联后的信息比特；对该每段级联后的信息比特进行编码，得到每段码字比特。
通过该实施方式，该第一通信装置可以在每段信息比特的尾部级联L比特的CRC后再执行编码等流程，以保证每段信息比特传输的正确性和完整性。
一种可能的实施方式中，C1段码字比特占用的传输资源单元的数量小于总的传输资源单元的数量时，该方法还包括：该第一通信装置使用该总的传输资源单元中的剩余传输资源单元，重传该C1段码字比特中的部分码字比特或者全部码字比特。
通过该实施方式，对于分段数量为C1的情况，若传输C1段码字比特之后，还有剩余传输资源单元时，可以使用剩余传输资源单元重传这C1段码字比特中的部分码字比特或全部的码字比特，以保证传输这C1段码字比特的完整性，以避免丢失的情况。
一种可能的实施方式中，该第一通信装置根据该第二通信装置的译码能力信息对第一信息比特进行分段处理，得到分段后的信息比特，可以包括：根据总的传输资源单元的数量、调制阶数，该第一信息比特以及该第二通信装置支持译码的码字的最大长度Nmax进行分段处理，Nmax为大于0的取值。
通过该实施方式，该第一通信装置可以根据总的传输资源单元的数量、调制阶数、第一信息比特以及该Nmax进行有效的分段处理，以保障后续该第二通信装置执行译码的性能。
一种可能的实施方式中，该第一通信装置根据总的传输资源单元的数量、调制阶数，该第一信息比特以及该第二通信装置支持译码的码字的最大长度Nmax进行分段处理，包括：先根据该总的传输资源单元的数量、该调制阶数以及该第二通信装置支持译码的码字的最大长度Nmax，确定初始分段数值C3；C3为正整数；再根据该总的传输资源单元的数量、该调制阶数、该初始分段数值C3，以及该第二通信装置支持译码的码字的最大长度Nmax，计算剩余的传输资源的比特数；若该剩余的传输资源的比特数小于预设值时，则确定分段数量等于C3；若该剩余的传输资源的比特数不小于该预设值时，则确定分段数量等于C3+1。
在本申请实施例中，该初始分段数值C3可以满足：
该剩余的传输资源的比特数可以满足：Brest＝Etotal×Qm-C3×Nmax。该分段数量C可以满足下式：
Brest<z·Nmax时，C＝C3；
Brest≥z·Nmax时，C＝C3+1；
其中，Qm为该调制阶数，Etotal为该总的传输资源单元的数量，Brest为该剩余的传输资源的比特数，z·Nmax为该预设值，z为大于0且小于1的值，为向下取整符号。
通过该实施方式，第一通信装置先根据总的传输资源单元的数量、该调制阶数以及该第二通信装置支持译码的码字的最大长度Nmax计算出初始分段数值，再基于初始分段数值进行分段的情况下，结合当前的调制阶数，计算出剩余的传输资源的比特数；若计算出的剩余的传输资源的比特数较少时(即小于预设值)，将实际分段数量设置为初始分段数值；若计算出的剩余的传输资源的比特数较多时(即不小于预设值)，将实际分段数量比初始分段数值多一个，从而可保证第二通信装置的译码性能，同时有效利用传输资源。
一种可能的实施方式中，C3段码字比特占用的传输资源单元的数量小于该总的传输资源单元的数量时，该方法还包括：该第一通信装置使用该总的传输资源单元中的剩余传输资源单元，重传该C3段码字比特中的部分码字比特或者全部码字比特。
通过该实施方式，对于分段数量为C3的情况，若传输C3段码字比特之后，还有剩余传输资源单元时，可以使用剩余传输资源单元重传这C3段码字比特中的部分码字比特或全部的码字比特，以保证传输这C3段码字比特的完整性，以避免丢失的情况。
一种可能的实施方式中，C3+1段码字比特中的前C3段码字比特占用的传输资源单元的数量小于总的传输资源单元的数量时，该方法还包括：该第一通信装置使用所述总的传输资源单元中的剩余传输资源单元，传输最后一段码字比特。
在本申请实施例中，C3+1段中的前C3段码字比特的大小等于该第二通信装置支持译码的码字的最大长度Nmax，且这前C3段中每段的码率相同；而最后一段码字比特的大小比Nmax小，因此相比前C3段的码率，最后一段的码率较大。
通过该实施方式，对于分段数量为C3+1的情况，先使用传输资源传输前C3段码字比特，使用剩余传输资源单元传输最后一段码字比特，从而在保证第二通信装置译码性能的同时，也可以保证传输资源有效被利用。
第二方面，本申请提供一种数据处理方法，该方法可由第二通信装置实施。其中，第二通信装置可以为但不限定于网络设备、终端设备、网络设备中的组件或终端设备中的组件。本申请中的组件例如可包括芯片、芯片系统、处理器、收发器、处理单元或收发单元中的至少一种。以执行主体是第二通信装置为例，该方法的步骤可以包括：输入码字比特；该码字比特是由分段后的信息比特进行编码处理得到的，该分段后的信息比特是第一通信装置根据该第二通信装置的译码能力信息对第一信息比特进行分段处理得到的；对该码字比特进行译码处理，得到该第一信息比特。
在本申请方案中，第一通信装置根据第二通信装置的译码能力信息对第一信息比特进行分段处理，再对分段后的信息比特进行编码处理后得到码字比特，再输出该码字比特；该第二通信装置获得该码字比特之后执行译码处理时的性能会较高。
在本申请实施例中，该第二通信装置还输出该第二通信装置的译码能力信息，可以包括但不限于以下几种方式：
方式一：输出第一信息，该第一信息用于指示该第二通信装置的译码能力信息。
方式二：输出该第二通信装置的能力信息，该第二通信装置的能力信息中的第一字段用于指示该第二通信装置的译码能力信息。
方式三：输出该第二通信装置的类型信息，该第二通信装置的类型信息中包括该第二通信装置的译码能力信息。
该第二通信装置可以通过上述几种方式灵活且有效地将该第二通信装置的译码能力信息输出给第一通信装置。
一种可能的实施方式中，将该第二通信装置支持译码的码字的最大长度Nmax作为该第二通信装置的译码能力信息，Nmax为大于0的取值。
通过该实施方式，将第二通信装置支持译码的码字的最大长度Nmax作为该第二通信装置的译码能 力信息，以用于分段处理中，可以有效保障后续该第二通信装置译码的性能。
另一种可能的实施方式中，该第二通信装置的译码能力信息为该第二通信装置支持译码的码字的最低码率Rmin；Rmin＝A/Nmax；其中A为所述第一信息比特的比特数，Nmax为该第二通信装置支持译码的码字的最大长度。
通过该实施方式，第一通信装置可以通过获得第二通信装置支持译码的码字的最低码率Rmin，进而也可以有效计算出该第二通信装置支持译码的码字的最大长度Nmax。
一种可能的实施方式中，该第二通信装置从该第一通信装置接收到C′段码字比特，C′为大于或者等于1的整数；那么该第二通信装置对该码字比特进行译码处理，得到该第一信息比特，可以包括：先对该C′段码字比特进行译码处理，得到C′段级联后的信息比特；再对该C′段级联后的信息比特去CRC码，得到该第一信息比特。
通过该实施方式，该第二通信装置可以有效对C′段码字比特进行译码，准确地得到第一信息比特。

为了更好的理解本申请实施例方案，下面先对本申请实施例的应用场景和存在的问题进行介绍。需要说明的是，该应用场景是为了让本申请实施例更容易被理解，而不应该视为对本申请所要求的保护范围的限定。
分段编码技术是指将整个数据分成若干段分别进行编码的编码技术，这种技术在无线通信场景中广泛应用。目前的分段方式主要包括极化码(polar code)的分段方式和低密度奇偶校验(low density parity check，LDPC)的分段方式。其中，polar码的分段方法是根据净荷大小确定分段数量，或者根据净荷大小和物理资源大小共同确定分段数量。LDPC的分段方式主要是根据码长和码率来确定分段数量。然而，目前的分段方式均没有考虑接收装置(例如终端设备)的能力信息(比如译码能力)和关键绩效指标(key performance indicator，KPI)的需求，从而导致接收装置执行译码的性能较低。
鉴于上述问题，目前亟需提出一种数据处理方法，可以根据接收装置的译码能力信息来对待编码数据进行分段处理，以有效的确保后续接收装置的译码性能。
本申请实施例提供的方法可以应用于第四代(4th generation，4G)通信系统，例如长期演进(long term evolution，LTE)通信系统，也可以应用于第五代(5th generation，5G)通信系统，例如5G新空口(new radio，NR)通信系统，或应用于未来的各种通信系统，例如第六代(6th generation，6G)通信系统。本申请实施例提供的方法还可以应用于窄带物联网系统(narrow band-internet of things，NB-IoT)、全球移动通信系统(global system for mobile communications，GSM)、增强型数据速率GSM演进系统(enhanced data rate for GSM evolution，EDGE)、宽带码分多址系统(wideband code division multiple access，WCDMA)、码分多址2000系统(code division multiple access，CDMA2000)、时分同步码分多址系统(time division-synchronization code division multiple access，TD-SCDMA)，或下一代5G移动通信系统的三大应用场景增强移动宽带(enhanced mobile broadband，eMBB)，超高可靠和低时延通信(ultra-reliable low-latency communications，URLLC)和增强型机器类型通信(enhanced machine-type communication，eMTC)。本申请实施例提供的方法还可以应用于卫星通信系统其中，所述卫星通信系统可以与上述通信系统相融合。此外，本申请实施例提出的方法还可能影响物理上行链路控制信道(physical uplink control channel，PUCCH)增强场景，通过最大似然(maximum likelihood，ML)检测来增强PUCCH的覆盖。

在另一种可能的场景中，由多个网络设备协作协助终端设备实现无线接入，不同网络设备分别实现基站的部分功能。例如，网络设备可以是集中式单元(central unit，CU)，分布式单元(distributed unit，DU)，CU-控制面(control plane，CP)，CU-用户面(user plane，UP)，或者无线单元(radio unit，RU)等。CU和DU可以是单独设置，或者也可以包括在同一个网元中，例如基带单元(baseband unit，BBU)中。RU可以包括在射频设备或者射频单元中，例如包括在射频拉远单元(remote radio unit，RRU)、有源天线处理单元(active antenna unit，AAU)或远程射频头(remote radio head，RRH)中。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网RAN中的网络设备，也可以将CU划分为核心网CN中的网络设备，在此不做限制。
应说明的是，在不同系统中，CU(或CU-CP和CU-UP)、或DU也可以有不同的名称，但是本领域的技术人员可以理解其含义。例如，在开放式无线接入网(open radio access network，O-RAN)系统中，CU也可以称为O-CU(开放式CU)，DU也可以称为O-DU，CU-CP也可以称为O-CU-CP，CU-UP也可以称为O-CU-UP，RU也可以称为O-RU。为描述方便，本申请中以CU，CU-CP，CU-UP、DU和RU为例进行描述。本申请中的CU(或CU-CP和CU-UP)、DU和RU中的任一单元，可以是通过软件模块、硬件模块、或者软件模块与硬件模块结合来实现。

下面结合图1所示的通信系统，对本申请实施例提供的方法做详细说明。
为了更好的理解本申请实施例提供的方案，下面先对本申请实施例所涉及的术语、概念、流程进行解释说明。需要说明的是，这些解释是为了让本申请实施例更容易被理解，而不应该视为对本申请所要求的保护范围的限定。
(1)信道编码。
如图2所示的通信系统传输流程，信道编码部分位于信源编码和调制之间，负责将信源产生的信息比特(或称为比特流)进行信道编码，再经过调制后，发送调制符号经过有噪声信道至接收端解调。接收端解调后进行信道译码，信道译码部分位于解调和信源译码之间，负责恢复出信源的信息比特。
本申请实施例中，涉及的核心网元为信道编码单元和信道译码单元。本申请中，信息比特的长度可称为负载长度(payload size)。
(2)循环冗余检验(cyclic redundancy check，CRC)编码。
CRC编码是信道编码的一种方式。在CRC编码过程中，对来自于信源的信息比特进行CRC编码，获得CRC码字。以信息比特长度为K为例，CRC码字包括K位信息比特，以及包括K位信息比特后拼接的L位校验比特(或称为校验码、CRC码等)，即CRC码字的长度为K+L比特。K、L为正整数。
对于一个校验比特的长度为L的CRC码字，存在一个最高次幂为L的CRC多项式gCRC，该gCRC可用于生成L位的校验比特，因此gCRC可称为这个校验比特的生成多项式。本申请中，幂可替换为指数，最高次幂可替换为最高指数。生成多项式可以由发送端与接收端协商确定，或者可以通过协议定义、预配置或预定义等方式确定，因此校验比特的长度即可根据该多项式确定。
这里举例介绍CRC校验码的生成过程。假设消息多项式为M(D)，其中，消息多项式根据需要发送的二进制的信息比特确定，如，二进制信息比特的第X位的值为1，则多项式中幂为X-1项的系数为1，二进制比特的第Y位的值为0，则多项式中幂为Y-1项的系数为0，或者说多项式不包括幂为Y的项，X、Y为正整数。在获得校验比特时，将M(D)左移L位，即每一项的幂均加L，多项式表示为M(D)*D^R，其中，*表示乘法运算。通过M(D)*D^R除以生成多项式gCRC得到的余数就是校验比特。
例如，假设校验比特的生成多项式为gCRCLmax＝gCRC4＝D^4+D+1，则其二进制表示为10011，共5位，其中Lmax＝4，即L＝4。假设发送端要发送数据序列的二进制比特为101011，共6位，则消息多项式为M(D)＝D^5+D^3+D+1，其中，^表示指数运算。进一步可得，M(D)*D^5＝D^9+D^7+D^5+D^4。用M(D)*D^5对应的二进制比特1010110000除以多项式gCRCLmax对应的二进制信息比特为10011，即按模2算法求得L位余数，该示例中余数的比特序列为0100，该余数即校验比特。因此经过CRC编码的CRC码字比特流为1010110100，其中前6位为原始数据9(即信息比特)，后4位为校验比特。发送端可对比特流1010110100做后续处理并发送。如果数据传输过程中没有出现错误，则接收端收到的包含校验比特的数据能够被校验比特的生成多项式的二进制比特10011除尽，如果传输过程中出现错误，则接收端收到的包含校验比特的数据将不能被10011除尽，因此接收端可识别传输错误。
本申请实施例中，网络设备和终端设备可分别作为发送端、接收端。比如在下行通信中，网络设备是发送端，终端设备是接收端，在上行通信中，终端设备是发送端，网络设备是接收端。网络设备可以是发送端或接收端。其中，如果发送端为网络设备，则接收端为终端设备，此时为下行通信。如果发送端为终端设备，则接收端为网络设备，此时为上行通信。此外，本申请也不排除发送端和接收端均为终端设备，此时发送端与接收端之间进行D2D通信。
(3)码率(code rade)。
码率又称编码速率或编码效率，是指数据流中有用部分(非冗余)的比例。也就是说，如果码率是k/n，单位是bit/symbol，则对每k位有用信息，编码器总共产生n位的数据，其中n-k是多余的。如果R是总比特率或数据信令速率(包括冗余错误编码)，净比特率(除去纠错码的有用比特率)≤R·k/n。这意味除去纠错码，编码率为1，总比特率或数据信令速率与净比特率或有用比特率相等。
(4)速率匹配(rate matching)。
编码前的数据块称为传输块(transport block，TB)，由于TB的比特数较大，所以发送端通常会将一个TB拆分为多个码块(code block，CB)，每个CB单独进行信道编码。由于用来传输码块的物理资源与待传输的码块物理时频资源可能不一致，故需要对待传输的码块进行比特重发或者打孔，以匹配物理时频资源的承受能力，这个过程称为速率匹配(rate matching)。多个经过信道编码后的CB需要经过速率匹配后，再进行交织、级联等处理后作为一个物理的数据块(码字)传输至接收端。
下面结合具体实施例介绍本申请的技术方案。
本申请实施例提供了一种数据处理方法，该方法可适用于但不限于图1所示的通信系统。该方法可由第一通信装置和第二通信装置实现，该第一通信装置可作为数据的发送端和/或接收端，该第二通信装置也可作为数据的发送端和/或接收端。也就是说，该第一通信装置作为发送端，那么该第二通信装置为接收端；或者，该第一通信装置作为接收端，那么该第二通信装置为发送端。该方法可以由第一通信装置、第二通信装置执行，或者可以由该第一通信装置、第二通信装置对应的部件(模块、芯片等)执行，又或者可以由与该第一通信装置、该第二通信装置对应匹配使用的装置执行，本申请实施例对该第一通信装置和第二通信装置对应的具体形态和数量均不做具体限定。请参阅图3所示，该方法的具体流程如下：
S301：第一通信装置获取第一信息比特和第二通信装置的译码能力信息。
在本申请实施例中，该第一通信装置可以为但不限于网络设备、或终端设备。
在本申请实施例中，信息比特可以指携带信息的比特；上述中，该第一信息比特可以称为待传输的净荷信息比特或原始信息比特。
在一种实施方式中，该第一通信装置获取该第二通信装置的译码能力信息可以通过但不限于以下几种方式实现：
方式一：从第二通信装置接收第一信息，该第一信息用于指示该第二通信装置的译码能力信息。
方式二：从第二通信装置接收该第二通信装置的能力信息，该第二通信装置的能力信息中的第一字段用于指示该第二通信装置的译码能力信息。
方式三：从第二通信装置接收该第二通信装置的类型信息，该第二通信装置的类型信息中包括该第二通信装置的译码能力信息。
在本申请实施例中，该第二通信装置的译码能力信息为该第二通信装置支持译码的码字的最大长度Nmax，Nmax为大于0的取值。或者该第二通信装置的译码能力信息为该第二通信装置支持译码的码字的最低码率Rmin；再按照公式Nmax＝A/Rmin，可以计算出该第二通信装置支持译码的码字的最大长度Nmax。
示例性地，基站(编码端/发送端)可以根据UE的译码能力设置若干个等级(或者若干个档位)。例如多个译码能力分别为Nmax(0)、Nmax(1)、Nmax(2)，…，Nmax(J-1)，对应的等级号j为：0,1,2，…，J-1。UE1可以向基站上报自身的等级号j为1，那么基站可以根据该UE1的等级号1，确定该UE1的支持译码的码字的最大长度为Nmax(1)。
S302：第一通信装置根据该第二通信装置的译码能力信息对第一信息比特进行分段处理，得到分段后的信息比特。
在本申请实施例中，该第一通信执行该步骤S302时，可以包括但不限于以下几种实现方式：
实现方式一：该第一通信装置可以根据码率、第一信息比特以及该第二通信装置支持译码的码字的最大长度Nmax进行分段处理。
在一种可能的实施方式中，该第一通信装置可以根据每段级联的循环冗余校验CRC的比特数L、该码率、Nmax、以及该第一信息比特的比特数，确定初始分段数值C′；其中，L为预设的大于或等于0的整数，C′为大于或者等于1的整数；
若码率大于或等于预设码率，则确定分段数量等于初始分段数值C′。
若码率小于预设码率，则确定分段数量等于C1，C1为小于或者等于C′的正整数。
在一些实施例中，若上述计算出的初始分段数值C′＝1，那么在码率小于预设码率的情况，分段数量C1＝C′＝1。
示例性地，该初始分段数值C′可以满足下公式：
Kcb为分段后的每段信息比特数的最大值，R为所述码率；A为该第一信息比特的比特数，为向上取整符号，/为除号。
在上述中，预设码率的取值大于0且小于1。例如，该预设码率等于1/4。y为大于或者等于1的整数。例如，y等于2。
在本申请实施例中，低于1/4的码率对应的编码增益接近重复发送的能量增益，因此当码率低于1/4 时，直接重复发送之前的码字比特，以减少编码操作的同时获取了重复发送的能量增益。
在上述公式(1)中是考虑每段信息比特级联了L比特的CRC，因此，Kcb中包括信息比特和校验比特。对于没有级联L比特的CRC的情况下，上述公式(1)可以更改为其中，Kcb是取整后的数。
进一步的，当分段数量等于C′时，可以计算出更新的第一信息比特的比特数A′＝C′·Kcb，该第一通信装置再将A′均匀的划分成C′段。当分段数量等于C1，可以计算出更新的第一信息比特的比特数A′＝C1·Kcb，该第一通信装置再将A′均匀的划分成C1段。
该实施方式可以应用该第一通信装置需要对该第一信息比特进行分段处理的情况下，比如该第一信息比特的比特数大于计算出的Kcb(Kcb是每段信息比特的最大比特数)。
在另一种可能的实施方式中，该第一通信装置确定分段分量等于1，即该第一通信装置直接将该第一信息比特进行编码处理后发送给第二通信装置。
实现方式二：该第一通信装置可以根据总的传输资源单元的数量、调制阶数，该第一信息比特以及该第二通信装置支持译码的码字的最大长度Nmax进行分段处理，Nmax为大于0的取值。
具体可以包括：先根据总的传输资源单元的数量、调制阶数以及第二通信装置支持译码的码字的最大长度Nmax，确定初始分段数值C3；C3为正整数；再根据该总的传输资源单元的数量、该调制阶数、该初始分段数值C3，以及该第二通信装置支持译码的码字的最大长度Nmax，计算剩余的传输资源的比特数；
若该剩余的传输资源的比特数小于预设值时，确定分段数量等于C3。在分段数量等于C3的情况下，第一通信装置可以将第一信息比特均匀的划分为C3段。
若该剩余的传输资源的比特数不小于该预设值时，确定分段数量等于C3+1。在分段数量等于C3+1的情况下，第一通信装置可以将第一信息比特均匀的划分为C3+1段。
示例性地，该初始分段数值C3可以满足下述公式(2)：
该剩余的传输资源的比特数可以满足下述公式(3)：
Brest＝Etotal×Qm-C3×Nmax    公式(3)
分段数量C可以满足下述公式(4)：
Brest<z·Nmax时，C＝C3；
Brest≥z·Nmax时，C＝C3+1；    公式(4)
其中，Qm为调制阶数，Etotal为总的传输资源单元的数量，Brest为剩余的传输资源的比特数，z·Nmax为该预设值，z为大于0且小于1的值，为向下取整符号，/为除号。
在本申请实施例中，该剩余的传输资源单元的数量Erest与剩余的传输资源的比特数Brest之间转换公式可以为：Erest＝Brest/Qm。
例如，z＝9/16，可见剩余的传输资源的比特数少于比Nmax的一半，即剩余的传输资源单元相对较少，那么相比初始分段值C3，不能再多分，这剩余的传输资源单元可以用于后续的重传。
当可见剩余的传输资源的比特数多于Nmax的一半，即剩余的传输资源单元相对较多，那么相比初始分段值C3，分段数量可以多1个(即可以多分一段)，这剩余的传输资源单元可以用于传输这多分的一段码字比特。
在本申请实施例中，z可以取值为可以保证速率匹配掉的比特数目(如缩短(shorten)或者打 孔(punctrue)掉的比特数目)小于母码长的一半。
S303：第一通信装置对该分段后的信息比特进行编码处理，得到码字比特。
基于上述实现方式一，该第一通信装置执行该步骤S303时，可以包括：在分段后的每段信息比特的尾部可以级联一段比特数为L的CRC，得到每段级联后的信息比特；再对每段级联后的信息比特进行编码，得到每段码字比特。
具体的，对于分段数量等于C′的情况：该第一通信装置可以对分段后的C′段信息比特中每段信息比特的后面级联L比特的CRC。再对每段级联后的信息比特进行编码处理。
对于分段数量等于C1的情况：对C1段信息比特中每段信息比特的后面级联L比特的CRC。再对每段级联后的信息比特进行编码处理。
针对分段分量等于1的情况，该第一通信装置可以直接将该第一信息比特进行编码处理，无需级联CRC。
基于上述实现方式二，该第一通信装置执行该步骤S303时，可以包括：
对于分段数量等于C3的情况：该第一通信装置可以对分段后的C3段信息比特中每段信息比特的后面级联L比特的CRC，再对每段级联后的信息比特进行编码处理。此情况下，C3段码字比特中每段码字比特的大小等于支持译码的码字的最大长度Nmax，且C3段中每段的码率相同。
对于分段数量等于C3+1的情况：该第一通信装置可以对分段后的C3段信息比特中每段信息比特的后面级联L比特的CRC，再对每段级联后的信息比特进行编码处理。
对于分段数量为C3+1的情况，相比初始分段数值C3，会将第一信息比特多分一段，因此相比按照初始分段数值划分后的每段信息比特的比特数，会使得前C3段中每段信息比特(即原始信息比特)的比特数量减少，而这前C3段码字比特的大小等于第二通信装置支持译码的码字的最大长度Nmax，从而使得前C3段中每段的码率稍降低。由于最后1段码字比特的大小比Nmax小，因此，最后1段对应的码率会较大。
S304：第一通信装置输出该码字比特；相应的，第二通信装置获得该码字比特。
在本申请实施例中，第一通信装置可以通过该第一通信装置中的部件(例如通信模块、天线等)向第二通信装置发送该码字比特；或者该第一通信装置可以通过该第一通信装置的通信接口输出该码字比特，相应的，该第二通信装置的通信接口获得该码字比特；又或者第一通信装置可以通过该第一通信装置对应的部件(例如芯片)输出该码字比特，相应的，该第二通信装置通过该第二通信装置对应的部件(例如芯片)获得该码字比特。因此，本申请对第一通信装置向第二通信装置传输该码字比特的具体实现方式不做限定。
例如，基站的DU(相当于第一通信装置)向UE(相当于第二通信装置)发送码字比特。
基于上述实现方式一，该第一通信装置在执行S304时，可以包括以下：
对于分段数量为C′的情况：该第一通信装置可以使用预先分配的总的传输资源单元将该C′段码字比特发送给第二通信装置。
在本申请实施例中，该第一通信装置发送这C′段码字比特的时域可以相同，也可以不同，对此不做具体的限定。
对于分段数量为C1的情况：该第一通信装置可以使用预先分配的总的传输资源单元来传输C1段码字比特，若发送该C1段码字比特所占用的传输资源单元的数量小于总的传输资源单元的数量时，该第一通信装置可以使用该总的传输资源单元中的剩余传输资源单元，重传该C1段码字比特中的部分码字比特或者全部码字比特。
在一些实施例中，上述中，该第一通信装置重传的该C1段码字比特中的部分码字比特可能是部分完整分段的码字比特，也可能是部分非完整分段的码字比特。
例如，第一通信装置重传该C1段码字比特中的C2段码字比特，C2为小于或等于C1的正整数值。
又例如，第一通信装置重传该C1段码字比特中的C2段码字比特，C2为大于0且小于C1的非整数值。
在本申请实施例中，重传的码字比特还可以指被重复的码字中从前往后依次的比特。
例如，编码的码字段数C1＝3段，重复发送的比特是第1段中第1,2,3，…,Nrep个比特，Nrep是重复发送的码字比特数量。Nrep小于该段码字长度时，发送直至剩余的传输资源允许承载的比特数量为止。 当Nrep大于该段码字长度时，继续从第2段码字的头部开始发送，以此类推，直至所有剩余的传输资源被使用完毕。
又例如，编码的码字段数C1＝1，即1段，若重传的比特是这段中第1,2,3，…,Nrep个比特，Nrep表示重复发送的码字比特的数量。Nrep大于这段码字的长度时，那么继续循环从头开始发送。Nrep小于这段码字的长度时，那么重复发送直至剩余的传输资源允许承载的比特数为止。
在另一些实施例中，若该第一通信装置使用该剩余传输资源单元，重传该C1段码字比特之后，该剩余传输资源单元中还有剩余的传输资源单元时，可以继续用于重传该C1段码字比特中的部分码字比特或全部码字比特。具体的重传情况可以参照上述的重传情况，此处不再详述。
基于上述实现方式二，该第一通信装置在执行S304时，可以包括以下：
对于分段数量为C3的情况：该第一通信装置可以使用预先分配的总的传输资源单元传输C3段码字比特。若该C3段码字比特占用的传输资源单元的数量小于该总的传输资源单元的数量时，使用该总的传输资源单元中的剩余传输资源单元，重传该C3段码字比特中的部分码字比特或全部码字比特；C3为正整数。
在一些实施例中，该第一通信装置重传的该C3段码字比特中的部分码字比特可能是部分完整分段的码字比特，也可能是部分非完整分段的码字比特。
例如，第一通信装置重传该C3段码字比特中的C4段码字比特，C4为小于或等于C3的正整数值。
又例如，第一通信装置重传该C3段码字比特中的C4段码字比特，C4为大于0且小于C3的非整数值。
具体的，可以参考上述实现方式一中例举的重传方式，此处不再一一详述。
对于分段数量为C3+1的情况：该第一通信装置可以使用预先分配的总的传输资源单元传输C3+1段码字比特中的前C3段码字比特。若该前C3段码字比特占用的传输资源单元的数量小于该总的传输资源单元的数量时，使用该总的传输资源单元中的剩余传输资源单元，传输最后一段码字比特。
S305：第二通信装置对该码字比特进行译码处理，得到第一信息比特。
基于上述实现方式一：该第二通信装置从第一通信装置接收到C′段码字比特，C′为大于或者等于1的整数。此情况下，该第一通信装置可以先对该C′段码字比特进行译码处理，得到C′段级联后的信息比特；再对该C′段级联后的信息比特去CRC码，得到第一信息比特。
该第二通信装置从该第一通信装置接收到C1段码字比特以及重传的C1段码字比特中的部分码字比特或者全部码字比特；C1为小于或者等于C′的正整数。此情况下，该第二通信装置可以先将该C1段码字比特对应的软比特与该重传的码字比特对应的软比特进行合并后译码，得到级联后的信息比特；再将级联后的信息比特，去掉级联的CRC码，得到第一信息比特。
在本申请实施例中，软比特可以指解调后的软比特信息LLR，也称为对数似然比(log likelihood ratio，LLR)。
例如，UE1接收到3个码字，分别为码字1、码字2、码字3，码字4，UE1还接收到了重传的码字1、码字2以及码字3。UE1将码字1对应的软比特和重传的码字1对应的软比特进行合并(拼接)后译码，将码字2对应的软比特和重传的码字2对应的软比特进行合并(拼接)后译码，将码字3对应的软比特和重传的码字3对应的软比特进行合并(拼接)后译码，将码字4对应的软比特单独译码。再将译码后的每段信息比特中的CRC比特去掉。
在一些实施例中，该第二通信装置接收到C1段码字比特和重传的C1(C2＝C1)段码字比特，还接收到第二次重传这C1段码字比特中的部分码字比特或全部码字比特，可以参照上述方式，执行合并后译码，此处不再详述。
基于上述实现方式二：该第二通信装置从第一通信装置接收到C3段码字比特以及重传的C3段码字比特中的部分码字比特或者全部码字比特。此情况下，该第二通信装置可以先将该C3段码字比特对应的软比特与该重传的码字比特对应的软比特进行合并后译码，得到级联后的信息比特；再对该级联后的信息比特去CRC码，得到第一信息比特。具体示例可以参照上述方式执行合并后译码，此处不再详细举例。
该第二通信装置从第一通信装置接收到C3+1段码字比特；C3为正整数。此情况下，该第二通信装置可以先对该C3+1段码字比特进行译码处理，得到C3+1段级联后的信息比特；对该C3+1段级联后的信息比特去CRC码，得到第一信息比特。
在本申请实施例中，C3+1中的前C3段码字比特的大小等于第二通信装置支持译码的码字的最大长度Nmax，C3+1中的前C3段的码率会稍微降低，然而C3+1中的最后1段码字比特的长度小于Nmax，因 而码率相对较大。
在本申请实施例，对于分段数量为1，即第一信息比特不分段处理的情况下，该第二通信装置收到码字比特，该码字比特是第二通信装置直接对第一信息比特进行编码处理后的数据，因此，该第二通信装置对该码字比特执行译码处理，即可得到该第一信息比特。
应说明的是，本申请实施例图3所述的方案是可以应用于图2所示的传输流程中，主要对其中的信道编码和信道译码过程进行详细介绍，本申请实施例图3所述的方案中还包括该传输流程中的其他的过程(例如调制)，具体实现流程可以参照现有技术的实现流程，此处不再一一详述。
综上所述，本申请实施例提出一种数据处理方法和装置，该方法包括：第一通信装置先获取第二通信装置的译码能力信息；然后根据该第二通信装置的译码能力信息对第一信息比特进行分段处理，得到分段后的信息比特；然后对该分段后的信息比特进行编码处理，得到码字比特；再输出该码字比特。该方法中，第一通信装置根据第二通信装置的译码能力信息对第一信息比特进行分段处理后再编码，进而输出给第二通信装置，可以保证该第二通信装置执行译码的性能。
基于上述图3所示的一种数据处理方法，下面通过几个具体的实施例进一步具体详细阐述。
实施例一：
实施例一中，以第一通信装置为基站，第二通信装置为UE1为例，对上述图3所述方案的步骤S302中分段处理的实现方式一进行详细介绍。
首先，基站获取UE1能支持的最大码长，并确定当前码率。然后，基站根据UE1能支持的最大码长和当前码率对目标载荷(相当于上述图3所述方案中的第一信息比特)的比特数进行均匀的分段。进一步的，基站将每段后级联L比特的CRC码。后续流程可参照图2所示的编码处理流程执行，如基站级联CRC码后的每段数据再进行后续的信道编码、调制，再通过信道发送给UE1，具体实现方式可参照现有技术实现，此处不再一一详述。
示例性地，图4A示出了一种基于UE1支持的最大码长和当前码率进行分段处理和CRC编码的流程图，参见图4A所示，该流程的具体解析如下：
步骤Step1：根据UE1支持的最大码长Nmax和当前码率R，确定每段消息比特数的最大值Kcb；
其中，Kcb满足下式：
步骤Step2：根据Kcb确定分段数量：
情况1：如果目标载荷的比特数不大于每段消息比特数的最大值(A≤Kcb)，则CRC的比特数L＝1，码块的数量(即分段数量)C＝1，待分段的净荷比特数A′等于目标载荷的比特数A。
情况2：否则的话，即目标载荷的比特数大于每段消息比特数的最大值，则CRC的比特数L＝11，码块的数量(即分段数量)C和待分段的净荷比特数A′通过下式计算得到：

A′＝C·Kcb；
步骤Step3：将步骤Step2中得到的A′个输入比特均匀分成C段，每段级联L比特CRC：
针对分段数量不为1的情况，即先将净载荷的比特数A′分为C段(即C个码块)，再在每段的尾部级联一段L比特的CRC。
比如，r表示码块对应的序号，r的取值为0到C-1，Kr为序号r的码块的比特数。码块r的比特数Kr计算如：K′＝A′/C。码块r的比特表示为
参见图4A所示的比特序列Crk计算循环式可知，针对序号r的码块，对应的比特序列如下：
k＝0，Cr0＝a′0；
k＝1，Cr1＝a′1；
k＝2，Cr2＝a′2；
……
k＝0，K′-L-1，CrK′-L-1＝a′K′-L-1。
参考现有CRC编码技术，根据计算CRC比特位如下：pr0,pr1,pr2,…,pr(L-1)。
参见图4A中所示，对于序号r的码块的CRC的L比特表示如下；
Crk＝pr(k+L-K′)；
其中，k的取值为K′-L到K′-1。
针对分段数量等于1的情况，即C＝1，则确定净载荷的比特数A′作为一个码块，该码块的比特可以如上述方式通过比特序列Crk来表示。
示例性地，图4B示出了上述实施例一中的分段传输方式，即当前码率R不低于预设的门限(例如)的情况，按照确定的分段数量进行分段，每段比特数为A’/C，每段占用的物理资源大小等于E/C。每段码率等于A/E。E表示基站分配的用于传输的总物理资源量，单位为比特(bit)。
例如，消息的总净荷大小A＝128bit，B＝1024bit，UE1的译码器支持的最大译码长度Nmax＝128，当前码率计算出Kcb＝16；进一步的，根据Kcb＝16，计算出分段数量 再将A划分为8段，每段比特数为16bit，每段占用的资源大小为128bit。如图4C所示。
实施例二：
实施例二中，基于上述实施例一所述方案的进一步介绍，即当前码块小于预设值(例如)时，则按照上述步骤Step1中的分段数量的一半进行分段处理，剩余的资源可以用于重传。
步骤Step1：根据UE1的译码器支持的最大译码码长Nmax和当前码率R，确定每段消息比特数的最大值Kcb；
该步骤Step1可以参照上述实施例一的步骤Step1实现，此处不再详述。
步骤Step2：根据Kcb确定分段数量C：
当前码率时，先参照上述实施例一中步骤Step2所述方式，确定初始码块的数量(相当于上述图3所述方案中的初始分段数值)C′如下：
接着，确定实际的分段数量进一步的，确定待分段的净荷比特数A′＝C·Kcb。
步骤Step3：将步骤Step2中得到的A′个输入比特均匀分成C段，每段级联L比特CRC：
该步骤Step3参照上述实施例一的步骤Step3实现，此处不再详述。
在该实施例二中，若当前码率R低于预设的门限(例如)，先根据上述实施例一中的分段方式确定初始分段数量C′，再将初始分段数量的一半作为实际需要分段的数量，即C＝C′/2；将A均匀分成C段，每段的编码的码率为2R，每段的码长为E/C，剩余资源可以用于重传这C段，如图5A所示。
例如，A＝128bit，总的传输资源的比特数B＝E×Qm＝1024bit，UE1的译码器支持的最大译码长度Nmax＝128bit。
当前码率先根据上述实施例一中的公式1计算出C′＝8；即C＝4；进而，将A划分为4段，每段编码成码率为每段净荷大小为A/C＝128/4＝32bit；每段占用的资源大小为128bit。对于剩余资源的比特数Brest＝1024-128×4＝512bit，这剩余资源用于重传编码好的码字。如图5B所示。
图5C示出了实施例一和实施例二在不同码率下对应的分段数量的译码性能，其横轴是信噪比(EsN0)，单位是dB，纵轴是误码率(block error rate，BLER)，通常曲线越低说明性能越好。从图5C可见，当码率低于预设门限Rth＝1/4时，采用实施例二的分段方式的性能更好，当码率高于预设门限Rth＝1/4时，采用实施例一的分段方式的性能更好。
实施例三：
实施例三中，以第一通信装置为基站，第二通信装置为UE1为例，对上述图3所述方案的步骤S302中分段处理的实现方式二进行详细介绍。首先，基站获取UE1支持译码的最大码长，并确定分配的总传输资源单元的数量。然后，基站根据UE1支持译码的最大码长和总传输资源单元的数量对目标载荷的比特数进行均匀的分段。进一步基站将每段后级联L比特的CRC码。参见图2所示的编码处理流程，后续基站级联CRC码后的每段数据再进行后续的信道编码、调制，再通过信道发送给UE1，具体实现方式可参照现有技术实现，此处不再一一详述。
下面为基于UE1支持的最大码长和当前码率进行分段处理和CRC编码的程序图，该程序如下：
步骤Step1：根据UE1支持的最大码长Nmax和当前总的资源数量Etotal，确定分段数量C。
确定当前调制阶数Qm；
先计算出初始分段数量C3(相当于上述图3所述方案中的C3)，如下式：
其中，为向下取整。
再计算剩余资源的比特数量Brest＝Etotal×Qm-C3×Nmax；
如果则确定分段数量C＝C3；
否则(即)，确定分段数量C＝C3+1。
如，UE1译码器支持的最大母码长为128bit，调制阶数Qm＝1，Btotal＝Etotal×Q＝260bit。

Brest＝Btotal-C3×Nmax＝260-2×128＝4；
可见则C＝C3＝2。
由于剩余资源数量没有达到UE1译码器支持的最大母码长的因此，少分一段，将剩余资源用于重传这2段比特数据。
又如，UE1译码器支持的最大母码长为128bit，调制阶数Qm＝1，Btotal＝Etotal×Qm＝360bit。

Brest＝Btotal-C3×Nmax＝360-2×128＝104；
可见则C＝C3+1＝3。
由于剩余资源数量大于UE1译码器支持的最大母码长的因此，可以多分一段。那么传输C3段之后，剩余资源用于传输最后1段。
步骤Step2：确定每段消息的比特数
即通过上述步骤Step1，确定了需要分段的数量C，进一步，将A比特的目标载荷均匀的划分为C段，每段的比特数 表示向上取整。接着，确定待分段的净荷比特数A′＝C·K′。
步骤Step3：将步骤Step2中得到的A′个输入比特均匀分成C段，每段级联L比特CRC：
该步骤Step3可以参照上述实施例一的步骤Step3实现，此处不再详述。
实施例四：
实施例四中，对上述图3所述方案中第一通信装置(即发送端或编码端)如何获取第二通信装置(即接收端或译码端)的译码能力进行介绍。在该实施例中，以基站作为编码端/发送端，UE作为译码端/接收端为例，基站和UE的数量不做具体限定，比如UE的数量可以为多个，基于目前终端设备的能力(UE Capability)主要涉及的3个协议(38.306、38.331、38.822)，参照表1所示，基站可以通过以下几种方式获得每个UE的译码能力：

示例性地，参见图6A所示，在38.306 4.2.7.10 phy-parameters章节中新增一个Filed指示UE的译码能力。图6A中字体加粗的部分是新增内容。
方式2：协议38.331中涉及的是UE能力查询和上报流程，信令结构等。基于现有协议内容，本申请实施例提出可以新增IE用于指示UE支持译码的最大码长和最小码率、最大分段数量。

方式3：协议38.822中涉及的是UE的特征(UE feature)，UE能力进一步将UE的特征翻译成协议所需要的语言。基于现有协议内容，本申请实施例提出可以新增UE译码能力的特征；例如在NR_UE_pow_sav_enh中增加内容(Components)，并说明是支持的低功耗译码，限制最大码长Nmax，最低码率Rmin、最小分段数量等参数。
