数据处理方法和通信设备
本申请要求于2017年02月06日提交中国专利局、申请号为201710065839.7、申请名称为“数据处理方法和通信设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，并且更具体地，涉及数据处理方法和通信设备。
背景技术
在通信系统中，信息数据在发送设备(例如，基站或者终端)和接收设备(例如，终端或者基站)之间传输，由于无线传播环境复杂多变，容易受到干扰，出现差错。为了可靠地发送信息数据，发送设备对信息数据进行CRC校验、信道编码、速率匹配、交织等处理，并将交织后的编码比特映射成调制符号发送给接收设备。接收设备接收到调制符号后，相应地通过解交织、解速率匹配、译码，CRC校验恢复成信息数据。这些过程可以减少传输差错，提高数据传输的可靠性。
低密度奇偶校验(low density parity check，LDPC)码是一类具有稀疏校验矩阵的线性分组编码，具有结构灵活，译码复杂度低的特点。由于它采用部分并行的迭代译码算法，从而比传统的Turbo码具有更高的吞吐率。LDPC码被认为是通信系统的下一代纠错码，可用来提高信道传输的可靠性和功率利用率；并可以广泛应用于空间通信、光纤通信、个人通信系统、ADSL和磁记录设备等。目前在新无线(new radio，NR)通信技术中已考虑采用LDPC码作为信道编码方式之一。
发送设备向接收设备发送的LDPC码具有一定的码率。该码率与接收设备的信息处理能力有关。为了提高通信的可靠性，发送设备应向具有不同信息处理能力的接收设备发送不同码率的信息。
发明内容
本申请提供一种数据处理方法和通信设备，能够提高通信的可靠性。
第一方面，提供了一种数据处理方法。所述数据处理方法包括：第一通信设备确定N CB，N CB是根据N CB,max、N IR、K W和C确定的N CB,max为第二通信设备的译码器支持的最大编码码块大小，N IR为所述第二通信设备的软信息缓存大小，K W为所述第一通信设备的循环缓存大小，C为所述第一通信设备向所述第二通信设备发送信息时的传输块中的码块数量；所述第一通信设备从长度为N CB的第一编码比特段中获取第二编码比特段。
该数据处理方法中，对于每个第二通信设备来说，第二编码比特段是从第一编码比特段中获取的，且第一编码比特段的长度N CB是根据第一通信设备的循环缓存大小以及第二通信设备的信息处理能力，从而使得向第二通信设备发送第二比特段时，可以节省第二 通信设备的存储开销，降低第二通信设备的译码复杂度。
从多个第二通信设备来说，不同第二通信设备对应的第一编码比特段的大小分别根据不同第二通信设备的信息处理能力确定的，因此可以提高通信的可靠性。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
如图1所示的通信系统100包括通信设备110和通信设备120。
通信设备110在发送信息数据时，可以根据支持的传输块的大小将信息数据划分成多个传输块(transmission block，TB)，并对每一传输块增加CRC校验。如果添加校验后的传输块大小超过最大码块长，则需要将传输块划分为若干码块(code block，CB)，每个码块中也可以增加码块CRC校验，还可以添加填充比特。通信设备110对每个码块分别进行信道编码，例如，采用LDPC编码，得到相应的编码码块。其中，每个编码码块中包括多个编码前的信息比特和编码生成的校验比特，统称为编码比特。
编码码块经过子块交织后保存在通信设备110的循环缓存中，通信设备110从循环缓存中选取一段编码比特，也就是一个编码比特段经过交织、映射为调制符号发送。通信设备110发生重传时将从循环缓存中选取另一编码比特段发送，如果循环缓存中的数据都传输了一遍，则回到循环缓存的前端再次编码比特。
通信设备120对接收到的调制符号解调，解交织后，将接收到的编码比特段的软值保存在软信息缓存(soft buffer)中相应位置。如果发生重传，通信设备120将每次重传的编码比特段的软值合并保存在软信息缓存中，这里的合并是指，如果两次接收到的编码比特的位置相同，则将两次接收到的该编码比特的软值合并。通信设备120对软信息缓存中的所有软值进行译码得到信息数据的码块。
需要说明的是，在本申请各实施例中，通信设备110可以是通信系统中的网络设备，如基站，则相应的通信设备120可以是终端。为便于理解下面对本申请中涉及到的一些名词做些说明。
本申请中，名词“网络”和“系统”经常交替使用，但本领域的技术人员可以理解其含义。
终端是一种具有通信功能的设备，可以包括具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备等。在不同的网络中终端可以叫做不同的名称，例如：用户设备，移动台，用户单元，站台，蜂窝电话，个人数字助理，无线调制解调器，无线通信设备，手持设备，膝上型电脑，无绳电话，无线本地环路台等。为描述方便，本申请中简称为终端。
基站(base station，BS)，也可称为基站设备，是一种将终端接入到无线网络的设 备，包括但不限于：传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(node B，NB)、基站控制器(base Station controller，BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如，home evolved nodeB，或home node B，HNB)、基带单元(base band unit，BBU)，或Wifi接入点(access point，AP)等。
图2是本申请一个实施例的数据处理方法的示意性流程图。应理解，图2示出了数据处理方法的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其他操作或者图2中的各个操作的变形。
S210，第一通信设备确定N CB，N CB是根据N CB,max、N IR、K W和C确定的，N CB,max为第二通信设备的译码器支持的最大编码码块大小，N IR为所述第二通信设备的软信息缓存大小，K W为所述第一通信设备的循环缓存大小，C为所述第一通信设备向所述第二通信设备发送信息时的传输块中的码块数量。
N IR可以是用于存储传输块软信息的缓存大小。此处所述的传输块可以是第一通信设备与第二通信设备之间的传输块。K W可以是一个码块的循环缓存的大小。
第一通信设备可以是图1中所示的通信设备110。
N CB可以称为第二通信设备接收第一通信设备发送的信息时实际使用的软信息缓存大小。第一通信设备的循环缓存也可以称为虚拟缓存，用于存储第一通信设备进行编码，如LDPC编码所得的编码比特。
第二通信设备可以是图1中所示的通信设备120。
N IR和N CB,max可以称为第二通信设备的信息处理能力。这些信息处理能力的不同取值可以通过第二通信设备的不同等级来体现。例如，以第二通信设备的处理能力为第二通信设备的软信息缓存的大小N IR为例，第二通信设备等级为1，其软信息缓存大小N IR为250000比特，等级为2，软信息缓存大小N IR为1000000比特。需要说明的是，上述只是方便举例说明，并不以此为限制。
第二通信设备的处理能力还可以包括寄存器的大小、译码器的能力等。
若第二通信设备的处理能力受限，第一通信设备在初传或者重传第二编码比特段时，基于第二通信设备的处理能力确定编码码块的大小，选择发送的编码比特段，可以节省第二通信设备的存储开销，并且降低第二通信设备的译码复杂度，提高通信的可靠性。
S220，第一通信设备从长度为N CB的第一编码比特段中获取第二编码比特段。
或者说，第一通信设备可以将循环缓存中长度为N CB第一编码比特段中获取第二编码比特段。
该数据处理方法中，对于每个第二通信设备来说，第二编码比特段是从第一编码比特段中获取的，且第一编码比特段的长度N CB是根据第一通信设备的循环缓存大小以及第二通信设备的信息处理能力，从而使得向第二通信设备发送第二比特段时，可以节省第二通信设备的存储开销，降低第二通信设备的译码复杂度。
从多个第二通信设备来说，不同第二通信设备对应的第一编码比特段的大小分别根据不同第二通信设备的信息处理能力确定的，因此可以提高通信的可靠性。
本申请实施例中，从第一编码比特段中获取的第二编码比特段可以不包括填充比特。如第一通信设备从第一编码比特段中获取的第二编码比特段时，第一通信设备可以只读取 第一编码比特段中的有效比特，跳过填充比特(如比特值为NULL)。
本申请实施例中，“N CB是根据N CB,max、N IR、K W和C确定的”，具体可以包括：
Figure PCTCN2018075220-appb-000009
其中，
Figure PCTCN2018075220-appb-000010
是向下取整，min(.)是对括号中的元素取最小值。
可见，第一编码比特段的大小小于或者等于第一通信设备的循环缓存大小。
本申请实施例的数据处理方法中，第一编码比特段可以是第三编码比特段中的比特段。第一通信设备可用于发送数据传输块，比如第一传输块，第一传输块可至少划分为一个码块。其中，第三编码比特段可以是第一通信设备根据第二通信设备的处理能力对第一传输块中的一个码块，例如，第一码块，进行处理得到的。
具体地，第三编码比特段可以是信息序列进行LDPC编码以及其他处理得到的比特。
进行LDPC编码所使用的LDPC基矩阵或LDPC检验矩阵中可以包含一种特殊的列，根据这些列进行编码得到的信息比特可以被打孔，可以将LDPC基矩阵或LDPC校验矩阵中的上述特殊的列称为打孔列。
例如，第一通信设备对第一码块采用LDPC基矩阵或LDPC校验矩阵编码得到第三编码比特段。第一通信设备可以将第三编码比特段直接送入循环缓存；也可以将第三编码比特段中打孔的信息比特(打孔的信息比特可以称为第一打孔比特段)删掉后再送入循环缓存，即送入循环缓存的第三编码比特段中不包括第一打孔比特段；或者将包括打孔信息比特的第三编码比特段送入循环缓存后，再将存入循环缓存中的第三编码比特段的打孔信息比特交织到第三编码比特段的末端。
若第三编码比特段中不包括打孔的信息比特，则从第三编码比特段中确定的第一编码比特段也不包括打孔的信息比特，相应地，第二编码比特段也就不包括打孔的信息比特，这样，第二通信设备接收第二编码比特段后，译码复杂度可以降低。
若第三编码比特段中包括打孔的信息比特，但打孔的信息比特已交织到第三编码比特段的尾端，则从第三编码比特段的前段开始确定第一编码比特段时，第一编码比特段可以不包括打孔的信息比特，如第一编码比特段的长度N CB小于K W-P时，其中P为第一打孔比特段包括的打孔信息比特；或者第一比特段可以只包括部分第一打孔比特段，如第一编码比特段的长度N CB大于K W-P时。
若第三编码比特段中包括打孔的信息比特，且打孔的信息比特位于第三编码比特段的前端，则第一编码比特段可以包括打孔的信息比特，但第一次从第一编码比特段中获取第二编码比特段时，可以跳过打孔的信息比特。重传时，第二编码比特段可以包括打孔的信息比特，也可以不包括打孔的信息比特。
本申请实施例中，第一通信设备从长度为N CB的第一编码比特段中获取第二编码比特段时，可以先确定发送的冗余版本RV，然后根据冗余版本RV确定要获取的第二编码比特段在第一编码比特段中的起始位置S，并从第一编码比特段中的起始位置S开始获取长度为n的第二编码比特段。其中，n为大于0的整数。
本申请实施的数据处理方法中，还可以包括：第一通信设备向第二通信设备发送第二编码比特段。
通信系统支持重传时，第一通信设备和第二通信设备之间会协商采用哪些冗余版本，每次重传发送时使用哪个冗余版本。其中，每个冗余版本可以用于指示第二编码比特段在 第一编码比特段中的一个起始位置，第一通信设备从该起始位置获取第二编码比特段。
通过每次发送第一编码比特段中不同的第二编码比特段，可以提高第二通信设备的译码成功率。
为了使得每次发送的第二编码比特段长度接近或者相等，不同冗余版本对应的起始位置可以分布在第一编码比特段中不同位置，常见的是等间隔分布。
第一通信设备对第一编码比特段进行初传时，通常使用冗余版本RV 0，RV 0的起始位置S 0可以是第一编码比特段中第p比特所在位置，此处p为大于或者等于0的整数。第p比特位为第一编码比特段中第一个非打孔信息比特。
以图3中所示的第一编码比特段的示意图为例，循环缓存中的第一编码比特段长度为179比特。第一编码比特段在循环缓存中为7行26列，第0列第1行所在的位置开始，RV 0对应的起始位置为第1列第0行，也就是第7比特，RV 1对应的起始位置为第7列第0行，也就是第49比特，RV 2对应的起始位置为第13列第0行，也就是第91比特，RV 3对应的起始位置为第19列第0行，也就是第133比特。可以看出各个冗余版本之间是等间隔分布。
若使用的冗余版本为RV 0，则第一通信设备从第1列开始按列顺序读取编码比特段，也就是从第7比特开始读取长度为42比特的编码比特段。若发送使用的冗余版本为RV 3，则第一通信设备30从第19列开始按列顺序读取编码比特段，需要注意的是第一通信设备30读到最后一个比特后，还要继续回到循环缓存开始的位置读第0列第1行，也就是读取总共长度为53比特的编码比特段。需要说明的是，此处只是方便举例，并不以此为限制。
本申请另一个实施例的数据处理方法的示意性流程图如图4所示。应理解，图4示出了数据处理方法的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其他操作或者图4中的各个操作的变形。
S410，第二通信设备获取第二编码比特段，第二编码比特段为第一通信设备从长度为N CB的第一编码比特段中获取的，N CB是所述第一通信设备根据N CB,max、N IR、K W和C确定的，N CB,max为第二通信设备的译码器支持的最大编码码块大小，N IR为第二通信设备的软信息缓存大小，K W为第一通信设备的循环缓存大小，C为第一通信设备向第二通信设备发送信息时的传输块中的码块数量。
S420，第二通信设备将第二编码比特段的软值比特合并保存在第二通信设备的软信息缓存中。
S430，第二通信设备根据软信息缓存进行译码。
该数据处理方法中，第二编码比特段所述的第一编码比特段的长度是根据N CB,max、N IR、K W和C确定的，使得第二通信设备可以接收长度合适的软信息，从而可以提高通信的可靠性和第二通信设备的译码复杂度。
本申请实施例中，N CB可以为
