Description

一种数据传输处理方法和装置 技术领域
本申请涉及但不限于通信领域，尤其涉及一种数据传输处理方法和装置。
背景技术
目前，各种手持设备如手机、电子腕表、平板电脑等的大量使用，对无线通信的应用需求迅猛增长。未来各种无线移动服务类型，如电子银行、电子健康和电子学习等等，预计在未来十年需要增加近1000倍的容量需求。以及由现在的以人为中心的通信会逐步转化成大量以物物之间通信，称之为物联网(Internet of Things)，这些应用可以使得人类的生活更高效、更舒适和更安全。未来第五代(5G)无线移动标准将逐步设计以满足这些需求。
在无线数字通信***中，包括发送端和接收端两个大部分，其中一般发送端包括信息源模块、信道编码模块、调制模块以及发射模块等，而接收端则包括接收信号模块、解调模块、信道译码模块和获取信源数据模块等。在数字通信中，信道编码是一个关键模块，主要是为了提高数据传输的可靠性，通过增加信道编码码字的冗余信息将数据在传输过程出现的错误纠正过来，从而可以抵抗信道中的衰落以及各种噪声对传输数据的影响。现在比较常用的信道编码技术，如LDPC(Low Density Parity Check Code，低密度奇偶校验码)编码、Turbo(涡轮)编码、卷积编码、RM(Reed和Muller的首字母)编码、RS(Reed-和Solomon，里德-索罗门)编码、BCH(BCH码取自Bose、Ray-Chaudhuri与Hocquenghem等3个人名的首字母)等。其中，LDPC的校验矩阵非常稀疏，故而译码复杂度不高，同时具有天然的译码并行性，可以并行译码获得比较高的译码吞吐量，而且性能非常接近香农极限，现在LDPC编码方式已用于多种通信***中；Turbo编码通过两个分量码对信息进行编码，利用两部分分量码进行迭代译码，可以提高译码性能，在中低码率时性能非常好，而且码率和码长可以比较灵活设置，很好适应各种通信数据，在现有的LTE(Long Term Evolution，长期演进)通信***中主要采用的是Turbo编码方式；卷积编码当前编码输出不仅与当前信息有关还和 以前的若干信息有关，类似于卷积特性，译码效果比较好，在许多***中也都有使用；RS编码是一种最短码距最大化码，而且译码可以采用流水线式译码，译码速度高速而且吞吐量高。为了让接收端能正确判断接收到的数据包或者编码码字中的信息块是正确的，在数字通信中还需要对数据包或者码字信息块进行校验，即添加一些校验序列，如循环冗余校验序列(CRC，Cyclical Redundancy Check)。
在实际通信***中，不仅需要信道编码技术来提高数据传输的可靠性，还需要重传机制来保证数据传输的可靠性和用户体验。常用的重传方法为混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)，是一种将前向纠错编码(FEC，Forward Error Correction)和自动重传请求(ARQ，Automatic Repeat Request)相结合而形成的技术。传统HARQ方案，它仅在ARQ的基础上引入了信道编码，即对发送数据包增加循环冗余校验(CRC)比特并进行前向信道编码。接收端对接收的数据进行信道译码和CRC校验，如果有错则放弃错误分组的数据，并向发送端反馈NACK(Negative Acknowledgement，否定应答)信息请求重传与上一帧相同的数据包。一般来说，通信***中，物理层都会设置最大重传次数的限制，防止由于信道长期处于恶劣的慢衰落而导致某个用户的数据包不断地重发，从而浪费信道资源。如果达到最大的重传次数时，接收端仍不能正确译码，则确定该数据包传输错误并丢弃该包，然后通知发送端发送新的数据包。还有另一种完全增量冗余方案，在这种方案下，信息比特经过编码后，将编码后的校验比特按照一定的周期打孔，根据码率兼容原则依次发送给接收端。接收端对已传的错误分组并不丢弃，而是与接收到的重传分组组合进行译码；其中重传数据并不是已传数据的简单复制，而是附加了冗余信息。接收端每次都进行组合译码，将之前接收的所有比特组合形成更低码率的码字，从而可以获得更大的编码增益，达到递增冗余的目的。以及还有多状态反馈信息的重传机制，即重传数据的比特数目由反馈信息进行指示，由于多状态反馈信息不仅仅携带了接收端正确与否的信息，而且还携带了一些与信道相关的信息，进而可以使得重传数据的比特数目和编码调制方案(MCS，Modulation Code Scheme)更加灵活配置。
尽管以上所述的数据混合重传方法中都会获得一定的吞吐量性能，但是 由于其重传过程中都是对原始包中的所有信道编码块进行增量冗余重传的，问题在于：有些信道编码块也许已经接收正确了，如果源数据包接收错误，还是要重传那些译码正确的信道编码块的冗余数据(此时无需再重传该部分数据)，这样会大大降低重传数据的效率，从而降低***吞吐量。而且，在未来5G无线移动通信***或者其他通信(WiFi通信，各种设备之间通信等)中，都需要传输大量的数据以支持各种用户应用需求以及提高用户体验。

详述
下文中将参考附图并结合实施例来详细说明本申请。需要说明的是，在不冲突的情况下，本申请中的实施例和实施例以及各个实例中的特征可以相互组合。
实施例1
在本实施例中提供了一种数据传输处理方法，图18是根据本发明实施例的数据传输处理方法的流程图，用于发送端，如图18所示，该流程包括如下步骤：
S1800、确定重传数据比特数目；
S1801、根据所述重传数据比特数目从第一数据集合中选择所述重传数据，或者从第一数据集合和第二数据集合中选择所述重传数据；
其中，所述第一数据集合至少包括校验包***比特的比特集合；所述第二数据集合至少包括原始包校验比特的比特集合；所述原始包包括多份数据包，所述校验包是对所述原始包进行包编码获得。
以上所述步骤S1801中，若重传数据比特数目小于或者等于N0，从第一数据集合中选择所述重传数据，其中，N0是一个预设的正整数。当重传数据比特数目较少时，可以直接从第一数据集合中选择，此时只需要传输校验包的数据即可让接收端较大概率能将所有信道编码块译码成功，占用较少重传传输资源，因此传输效率较高，可以提高***的吞吐量。
在示例性实施方式中，在步骤S1801中，校验包是对所述原始包进行包编码获得，所述包编码方法，包括：对原始包中所有E份数据包的相同索引的E比特构成的比特集合进行校验编码，获得n份长度都为e比特的校验集合，所述n份校验集合中索引都为i的n比特构成第i个子校验包，i＝0,1,…,(e-1)，获得e份子校验包，所述校验包由e份子校验包构成，其中，E是所述原始包中数据包数目，n是所述原始包中的数据包比特数目，e是大于0的整数，所述校验编码采用以下编码方式之一：单奇偶校验编码、BCH编码、RM编码、RS编码。
所述包编码如图2所示，对原始包中所有E份数据包200的索引为j的E比特202进行校验编码210，获得第j份长度为e比特的校验集合203，j＝0,1,…,(n-1)，可以获得n份校验集合，所有校验集合中索引都为i的n比特构成第i个子校验包Pi，其中，i＝0,1,…,(e-1)，从而获得由e个子校验包构成的校验包201。所述校验编码也可以是以上所述的编码方法的缩短编码和删余编码中至少一种，获得相应比特数目为e比特的校验集合。包编码方法的好处在于可以将所有信道编码块联系起来，这样在接收译码时可以采用迭代译码方法，以提高译码性能。所述单奇偶校验编码，则只有e＝1比特的校验集合，如对长度为y的比特集合进行单奇偶校验编码，则该1比特的校验集合等于比特集合中所有y比特的累积异或，如p0＝a0⊕a1⊕…⊕a(y-1)，其中，p0是校验比特，a0…a(y-1)是比特集合；所述BCH编码是一种循环码(取自Bose、Ray-Chaudhuri与Hocquenghem的缩写)，具有完善的代数理论计算，能纠正多个错误，其编码过程是根据生成多项式g(x)＝g0×x(e-1)+g1×x(e-2)+…+g(e-1)进行编码，输入比特集合也用多项式表示，如输入比特集合为[a0…a(t-1)]，采用多项式可以表示为a(x)＝a0×x(t-1)+a1×x(t-2)+…+a(t-1)，根据BCH编码规则c(x)＝a(x)g(x)可以计算出BCH编码字，其中，c(x)是BCH编码字，从c(x)中取出校验比特即可得到校验集合，可以从校验比特中选择部分比特构成校验集合；RS编码是BCH编码的一个之类，是多元域编码，也需要一个生成多项式g(x)，输入多元域多项式为a(x)＝a0×x(t-1)+a1×x(t-2)+…+a(t-1)，此时，g(x)和a(x)中的系数都是多元域的，根据c(x)＝a(x)g(x)可以计算出RS编码字c(x)，其中，多元域是指多元伽罗华域，例如采用4比特表示，则是16元域；RM编码是一种分组码，需提供一种生成矩阵G，输入信息比特序 列为s，则RM码字为c＝G*s，此处码字c需要是***码，将RM码字c的校验比特取出来即可以获得校验集合；所述校验编码还可以包括e比特校验编码如下：输入比特集合为s，对s的一个子集Set0进行二进制异或相加，获得第0个校验比特；对比特集合s和第0个校验比特组成的新集合的一个子集Set1进行二进制异或相加，获得第1个校验比特；对比特集合s和第0个校验比特、第1个校验比特组成的新集合的一个子集Set2进行二进制异或相加，获得第2个校验比特；依次类推，对s和已经计算的e-1个校验比特组成的新集合的一个子集Set(e)进行二进制异或相加，获得第(e-1)个校验比特，其中，所述Set0＝[0,1,2,…,(n-1)]，Set1为0到n的全部偶数或者奇数。通过对编码信息包进行包编码，可以将多个信道编码块进行联系起来，有益于提高译码增益，并且通过该包编码方案可以使得重传数据的比特数目范围较大，如果较小可以直接传输校验包的数据，灵活性非常大。
如图3所示，所述原始包300中第j份数据包Sj中包含Cj份编码后的信道编码块，其中，Cj是大于0的整数，所述信道编码是以下编码方式之一：turbo编码、LDPC编码、卷积编码、Polar编码。通过包编码方法获得校验包301，所述包编码方法如上所述。如图3所示，校验包中的第i份子校验包中也包括C份数据块，由于所述C份数据块是由多份信道编码块通过包编码得到，所述C份数据块也属于相应信道编码码字空间，所以也可以进行信道译码，所以所述校验包中的C份数据块也有***比特和校验比特，***比特是完全由原始包中的***比特通过包编码获得，而校验比特是完全由原始包中的校验比特通过包编码获得，即，所述校验包***比特是原始包***比特进行包编码得到，校验包校验比特是原始包校验比特进行包编码得到，而，所述原始包校验比特是原始包中所有信道编码块的校验比特，原始包***比特是原始包中所有信道编码块的***比特；所述C等于C0,C1,…,C(E-1)中的最大值，i＝0,1,…,(e-1)。其中，原始包***比特是所有信道编码块中进入信道编码的信息比特(所有信道编码的***比特)，如图3所示；原始包校验比特是所有信道编码块中除了***比特以外的比特(所有信道编码的校验或冗余比特)，如图3所示；所述的校验包***比特是所有原始包***比特通过包编码后获得的比特，如图3所示；校验包***比特是校验包中除了***比特以外的比特，如图3所示。
在包编码之前，对原始包的第i份数据包进行填充n-ni比特，使得每份数据包的比特数目都达到n比特，其中，i＝0,1,…,(E-1)，ni是第i份数据包比特数目，ni是大于或等于0的整数。目的在于，在包编码之前先让原始包中的每份数据包的比特数目相等，方便包编码的执行，所述填充的比特是“0”或者一些伪比特，其对包编码中的校验编码不起作用。
所述包编码中，若校验编码采用单奇偶校验编码，则所述校验包只包含1个子校验包。即，校验包可以表示为P0＝S0⊕S1⊕…⊕S(E-1)，其中P0是校验包，S0、S1、…、S(E-1)是所述原始包中E份数据包。此时，单奇偶校验编码的编码较为简单，直接采用累积异或即可实现，而且译码端也是比较简单，如可以采用min-sum算法来实现，性能也可以获得较大改善。
在示例性实施方式中，所述第一数据集合包括校验包的所有比特，即如图3所示，包括校验包的***比特和校验比特；第二数据集合包括原始包的所有校验比特，如图3所示原始包校验比特。或者，所述第一数据集合包括校验包的所有比特，即如图3所示，包括校验包***比特和校验比特；第二数据集合包括原始包的所有比特，如图3所示原始包的***比特和校验比特。此时，所述预设的正整数N0等于首传数据中数据包的比特数目，即等于如图3所示的原始包中任一数据包的比特数目。
也可以，所述第一数据集合包括校验包的所有***比特，即仅包括校验包的***比特，此时从第一数据集合进行循环比特选择是按信道编码块的***比特块为单位进行选择的；第二数据集合包括原始包的校验比特和校验包的校验比特。或者，所述第一数据集合包括校验包的所有***比特，即只包括校验包的***比特；第二数据集合包括原始包的所有比特。或者，所述第一数据集合包括校验包的所有***比特，第二数据集合包括原始包的校验比特。此时，所述N0等于校验包的***比特数目。
在以上所述的重传数据中，包括：重传数据中的多份重传数据包的比特数目中，最大值与最小值的差小于或等于1。如此，有利于原始包中每份数据包的比特数目尽量相等，使得其性能基本一致，不会出现“短板”效应，增加重传数据的整体接收误包率性能。
根据反馈信息和首传数据确定重传数据的比特数目，若所述接收端的反 馈信息指示错误接收，则重传数据比特数目等于以下参数之一：首传数据的总比特数目、首传数据中的任一份数据包的比特数目；此时，所述接收端的反馈信息至少包括2种错误状态NACK1、NACK2，指示所述不同重传数据比特数目。或者，若所述接收端的反馈信息指示错误接收，则重传数据比特数目等于以下参数之一：首传数据的总比特数目、Q0、首传数据中的任一份数据包的比特数目；其中，Q0是大于首传数据中任一份数据包的比特数目且小于首传数据总比特数目的整数；此时，所述接收端的反馈信息至少包括3种错误状态，指示所述不同重传数据比特数目。
在示例性实施方式中，所述重传数据中，重传数据比特数目等于调制阶数和预设重传资源数目的乘积，调制阶数是单个星座调制符号携带的比特数，如BPSK(二进制相移键控)调制阶数等于1，如QPSK(正交相移键控)调制阶数等于2，8PSK(八相移键控)调制阶数等于3，如16QAM(16进制正交振幅调制)调制阶数等于4，如32QAM(32进制正交振幅调制)调制阶数等于5，如64QAM(64进制正交振幅调制)调制阶数等于6，如128QAM(128进制正交振幅调制)调制阶数等于7，如256QAM(256进制正交振幅调制)调制阶数等于8等等；预设重传资源数目是***预设的发送传输的星座调制符号数。所述重传校验包的比特数目等于重传数据比特数目与所有多份重传数据包总比特数目的差值。或者，重传数据比特数目等于首传数据总比特数目。或者，重传数据比特数目等于预设的一个正整数，该正整数可以由反馈信息指示或者***预设，以及其他不限于所述方式获得该正整数。所述重传数据是从第一数据集合和第二数据集合中至少一项循环选择，其中数据从循环缓存中取出数据，如果取到末尾比特则从首比特开始取，直到取到相应比特数目为止，所述循环选择的起始比特按重传版本号获得，或者等于上一传输数据的比特在第一数据集合或第二数据集合中的索引位置加一。如图13所示，第二数据集合包括原始包的所有比特1300(包括原始包***比特和原始包校验比特)，第一数据集合包括校验包***比特1301(第一数据集合不包括校验包校验比特，所以图中没有画出)，所述对第二数据集合进行循环选择，按信道编码块为单位进行比特选择，以及每份数据包中的所有进行比特选择后的信道编码块的比特数目中，最大值和最小值的差值小于或等于1，当比特选择的比特已经是对应信道编码块的且属于第二数据集合的 尾比特，则从该信道编码块的首比特开始选择，如第0份数据包S0中的第0份信道编码块的循环比特选择为从起始比特开始收集比特数据，当达到尾比特时从首比特开始选择；所述从第一数据集合及性能循环选择，是按每份子校验包中对应每份***比特率为单位进行循环比特选择，当选择到***比特块的尾比特则从首比特开始进行选择。
实施例2
在本实施例中提供了一种数据传输处理装置，图4是根据本发明实施例的数据传输处理装置的框图，用于发送端，如图4所示，重传数据处理模块401包括如下单元：
确定单元，设置为确定重传数据比特数目；
第二比特选择单元，设置为根据重传数据比特数目，选择以下方式之一获得所述重传数据：a、所述重传数据从第一数据集合中选择；b、所述重传数据从第二数据集合和第一数据集合中至少一项选择；其中，所述第一数据集合是至少包括校验包***比特的比特集合，所述第二数据集合是至少包括原始包校验比特的比特集合，原始包包含多份数据包，所述校验包是对所述原始包进行包编码获得。

实施例3
在本实施例中提供了一种数据传输处理方法，用于发送端，包括如下步骤：
S0，接收接收端的反馈信息；
S1，若反馈信息指示错误接收时，而且若是第1次重传，则向接收端发送第1次重传数据，其中包括：确定重传数据比特数目；根据重传数据比特数目，选择以下方式之一获得所述重传数据：a、所述重传数据从第一数据集合中选择；b、所述重传数据从第二数据集合和第一数据集合中至少一个选择；其中，所述第一数据集合是至少包括校验包***比特的比特集合，所述第二数据集合是至少包括原始包校验比特的比特集合，原始包包含多份数据包，所述校验包是对所述原始包进行包编码获得。
在示例性实施方式中，与所述第1次重传数据相对应的首传数据的处理过程如图6所示，包括以下步骤：S600，对源数据包进行分割获得E份子数据块；S601，对第j份子数据块进行信道编码获得第j份数据包，j＝0,1,…,(E-1)，获得由E份数据包构成的原始包；S602，按预定码率对原始包进行比特选择得到首传数据。
所述校验包是由所述原始包进行包编码获得，其中，以上所述的包编码方法如实施例1所述。进行包编码的目的在于，将多份数据块通过包编码建立联系，在接收端进行译码时可以获得比较大增益。包编码的校验包主要在重传数据中传输，可以在不改变首传数据的情况下，既可以兼容原来通信***，并能提高重传数据的吞吐量性能。
在示例性实施方式中，在步骤S1中，所述重传数据的比特数目等于首传数据的比特数目；以及，所述重传数据中，比特选择输出的E份数据包的比特数目中，最大值与最小值的差值小于或等于1，E是大于1的整数。
在示例性实施方式中，所述包编码中采用单奇偶校验编码，即校验包中只包含1份子校验包，长度为n，在步骤S1中，所述比特选择得到的校验包的比特数目等于重传数据比特数目与所有比特选择得到的E份重传数据包的总比特数目的差值，其中，重传数据比特数目等于首传数据比特数目。所述多份重传数据包的比特数目为：有d1份重传数据包的比特数目为n1，有E-d1个信道编码块的长度为n1-1，其中，

d1＝mod(N-n',n1-1)；或者，都等于[(N-n')/(E+1)]；其中，N是重传数据比特数目，n'是首传数据中任一份数据包的比特数目，E是原始包中数据包的份数，计算式
Figure PCTCN2017080294-appb-000002
表示大 于或等于实数x的最小整数，mod(x1,x2)表示整数x2对整数x1的取模操作，计算式[x]表示四舍五入取整数、或者向下取整数、或者向上取整数。重传数据比特数目等于首传数据比特数目，可以根据首传数据比特数目来计算重传数据的校验包和每份数据包的比特数目，计算简单，而且所占资源和首传数据是一样的，可以在相同的调度资源上传输，不需要重新发送指令来指示资源调度信息。或者所述重传数据比特数目等于调制阶数和***预设资源数目的乘积，此时，所述的重传数据的校验包和每份数据包的比特数目由***分配的资源数目来计算，此时可以更充分利用当前***资源，在新的***资源上传输，资源利用率高。
实施例4
在本实施例中提供了一种数据传输处理方法，用于接收端，如图14所示，包括如下步骤：
S1400，接收发送端的传输数据；
S1401，对接收到的传输数据进行解码；
S1402，若所述解码结果错误，向发送端发送反馈信息；其中，发送端可以根据所述反馈信息和首传数据确定重传数据比特数目，选择以下方式之一获得所述重传数据：a、所述重传数据从第一数据集合中选择；b、所述重传数据从第二数据集合和第一数据集合中至少一个选择；其中，所述第一数据集合是至少包括校验包***比特的比特集合，所述第二数据集合是至少包括原始包校验比特的比特集合，原始包包含多份数据包，所述校验包是对所述原始包进行包编码获得。
步骤S1402中，若所述接收的传输数据误码块率大于T(i-1)且小于Ti，发送反馈信息i，用于指示重传数据比特数目等于Di；其中，Ti是预设阈值集合T的第i个元素，且0<T(i-1)<Ti<1，反馈信息i是反馈信息集合中第i个元素，Di是预设重传数据比特数目集合D中第i个元素，Di是大于0的整数，且D(i-1)<Di；所述接收的传输数据误码块率是接收Q份传输数据中的所有误码块数与所述接收Q份传输数据中所有信道编码块数的比值，其中，Q是正整数。一般来说，预设阈值集合T中第0个元素T0＝0；反馈信息集合中第0个元素为ACK(指示正确接收)，其他元素表示错误接收；重传数 据比特数目集合D中第0个元素D0＝0。所述方法的益处为，反馈信息是多状态的，而且重传数据比特数目可以灵活设置，能适应信道的变化，重传数据只需要预估的比特数目，可以大大提高资源利用率，可以提高整个***的吞吐量性能以及***总和容量。
在步骤S1402中，包括：若所述接收的传输数据的误码块率大于0且小于T’，发送反馈信息1(NACK1)，指示重传数据比特数目等于首传数据中的任一份数据包比特数目；若所述接收的传输数据的误码块率大于或等于T’，发送反馈信息2(NACK2)，指示重传数据比特数目等于首传数据的比特数目；其中，T’是大于0且小于1的实数，误码块率是所述接收传输数据中的误码块数与所***块数的比值。
在步骤S1402中，也可以包括：若所述接收的传输数据的误码块率大于0且小于T0，发送反馈信息1(NACK1)，指示重传数据比特数目等于首传数据中的任一份数据包比特数目；若所述接收的传输数据的误码块率大于等于T0且小于T1，发送反馈信2(NACK2)，指示重传数据比特数目等于Q0；若所述接收的传输数据的误码块率大于或等于T1，发送反馈信息3(NACK3)，指示重传数据比特数目等于首传数据的比特数目；其中，0<T0<T1<1，误码块率是所述接收传输数据中的误码块数与所***块数的比值，Q0是大于首传数据中任一份数据包的比特数目且小于首传数据总比特数目的整数。

S1903、对所述H1份极化编码块的全部比特或者部分比特进行包编码获得H2份子校验包，所述H1份极化编码块和所述H2份子校验包构成首传数据，其中，H1是大于1的整数，H2是大于0的整数，I是大于或者等于0的整数。

下面以一些实例说明本申请。
实例1
根据本申请的一个方面，用于无线数据通信***，其中可以用于一种基站，所述基站可以包括：接入点(AP，Access Point)、或可以称为节点B(node B)、无线电网络控制器(RNC)、演进型Node B(Evolved Node B，eNB)、基站控制器(BSC)、基站收发台(BTS)、基站(BS)、收发机功能体(TF)、无线电路由器、无线电收发机、基本服务单元(BSS)、扩展服务单元(ESS)、无线电基站(RBS)，或一些其它术语。
如图7所示，是一个采用本申请的相关多个方面的无线通信***的一个链路实例，用于车载***与基站之间的通信。发送端700发送数据703到接收端701，而接收端701根据接收数据正确情况发送反馈信号702到发送端700；所述发送端700可以是基站，或者也可以是其他如上所述的设备或装置；所述接收端701可以是车载***，或者，也可以是平板电脑、阅读机、电子表等手持设备，以及其他需要接入互联网的电子设备或者互联的电子设备、无线调制解调器、膝上型计算机、个人计算机、车载设备、手机、无线接入节点、传感器节点等。
本申请所述的各种算法和方法以及装置模块可用于在无线通信***中的基站700和车载***701之间进行传输。本申请的传输处理方法也可以用于LTE通信***、WiFi***、高频通信***以及未来的5G通信***等。所需要传输的源数据包的长度为4240比特，信道编码采用LTE***中的Turbo编码，***设定的编码码率为1/2，星座调制方式为16QAM，最大重传次数 M＝3(即，最大传输次数为4次)。如图7所示，基站700向车载***701发送业务数据，并接收车载***701发送的反馈信息，所述发送的业务数据如果是首传数据，则首传数据的处理过程包括以下步骤：
1、对长度为4240比特的源数据包进行分割获得d＝10份子数据块，每份子数据块的比特数目为424；
2、对第j份子数据块进行Turbo编码获得第j份数据包，j＝0,1,…,9，获得由d＝10份数据包构成的原始包；所述第j份数据包中包含Cj＝1份编码后的Turbo编码块，在进行Turbo编码之前先添加8比特CRC序列，使得每份子数据块的长度达到432比特，对所述432比特的子数据块进行Turbo编码获得长度为1308比特的编码后的Turbo编码块；
3、按预定码率1/2对原始包进行比特选择得到首传数据。所述的比特选择采用循环选择方法，将长度为1308比特的Turbo编码块置于一循环缓存中，比特选择时依次取出比特数据，如果到达尾比特则从首比特开始进行选择。由于预定码率为1/2，所以每个速率匹配后的Turbo编码块的比特数目为864，从而首传数据的总比特数目为8640。如果按顺序进行比特选择，则选择的起始索引位置为0，即从首比特开始，而下一次重传数据则在其尾比特索引位置加一的索引位置开始选择，本实例的下一次传输的比特选择起始索引位置为864；而如果采用版本号进行比特选择，则比特选择的起始索引位置由重传版本号ri、Turbo编码块总长度Ncb和交织深度Rsb有关，本实例中的起始比特索引位置为sti＝Rsb×(2[Ncb/(8Rsb)]×ri+2)，所述版本号集合为r＝[0 2 1 3]，集合中包含4个元素(最多4次传输数据)，对应每个传输次数的版本号，第0个元素是首次传输的版本号，第1元素是第1次重传数据的版本号，第2元素是第2次重传数据的版本号，第3元素是第3次重传数据的版本号。由于本实例中，Rsb＝14，Ncb＝1344，r0＝0，此时首传数据时，st0＝28，以及对应重传数据分别为st1＝700、st2＝364、st3＝1036。
4、发送所述比特选择后的d＝10份数据包，比特数目都为864比特，每份数据包包括1份速率匹配后的Turbo编码块，其中速率匹配中的比特选择的起始索引位置为28。按调制方式为16QAM(即调制阶数为M＝4)对所述首传数据(d＝10份数据包)进行星座调制，并向车载***701发送所述调制 后的数据流。
当基站700向车载***701发送完首传数据后，接收车载***701的反馈信息，若反馈信息指示数据接收错误，则按以下步骤进行操作：
1、对原始包中所有d＝10份数据包的相同索引的d＝10比特构成的比特集合进行校验编码(本实例中校验编码采用单奇偶校验编码，即e＝1)，获得n＝1308份长度都为e＝1比特的校验集合，由于此时校验集合只有1比特，所以所述n＝1308份校验集合构成第0个子校验包，获得1份子校验包p0，所述校验包由e＝1份子校验包构成。亦可表述如下：校验包可以表示为p0＝a0⊕a1⊕…⊕a(d-1)，其中p0是校验包，a0、a1、…、a(d-1)是所述原始包中d份数据包。此时，原始包中每份数据包只包含1份Turbo编码块，校验包只包含1份子校验包，其中原始包800中的***比特和校验比特、以及校验包801中的***比特和校验比特分别如图8所示，第一数据集合是包括校验包***比特和校验比特的比特集合(校验包的所有比特)，第二数据集合是包括原始包***比特和校验比特的比特集合(原始包的所有比特)。
2、依据反馈信息，确定重传数据比特数目；其中，反馈信息至少包括3种状态(ACK，NACK1，NACK2)，若接收为ACK则表示正确接收；若接收为NACK1则指示错误接收，第i次重传数据的比特数目为864×i，i＝1,2,3；若接收为NACK2则指示错误接收，第i次重传数据的比特数目为8640。
3、根据重传数据比特数目，选择以下方式之一获得所述重传数据：a、所述重传数据从第一数据集合中选择；b、所述重传数据从第二数据集合中选择。第i次重传数据中，预设的正整数N0等于首传数据中的数据包比特数目的t＝i倍，i＝1,2,3，首传数据中数据包比特数目为864，所以对应第1(或2或3)次重传数据，N0等于864(或864×2或864×3)。若重传数据比特数目小于或等于N0，选择方式a，若重传数据比特数目大于N0，选择方式b。若所述重传数据的比特数目为8640，从第二数据集合中进行选择，则选择出的每份数据包的比特数目为864，即每个Turbo码的比特选择出864比特，按重传版本号进行选择。
根据以上介绍的重传数据方式，每次传输数据的调制方式都为16QAM(调制阶数为4)，AWGN(加性高斯白噪声)信道下，***归一化吞吐量 性能比较如图9所示，可以看出，所述传输处理方法都可以获得较大吞吐量增益，在第1次重传900约有1.1dB的信噪比(SNR，Signal to Noise Ratio)增益，在第2次重传901约有0.9dB的信噪比增益，在第3次重传902约有0.6dB的信噪比增益，该方法具有较大创新性。增益主要来自于两个方面，第一方面是重传数据中包含比特数目较小的校验包的比特集合，资源占用少，第二方面是包编码方法带来的编码增益，将多个数据包通过包编码方法联系起来类似构成一个大的信道编码块，使源数据包的误包率性能大为降低。
本实例以及在以下实例中所用到的Turbo编码方法都采用LTE标准中规定的编码方法。其编码过程如下：
在LTE***中，Turbo编码方案采用并行级联卷积编码(PCCC，Parallel Concatenated Convolutional Code)，它使用了两个8状态子编码器和一个Turbo码内交织器。Turbo编码器的码率为1/3，PCCC中8状态子编码器的传输函数为：G(D)＝[1,g1(D)/g0(D)]，g0(D)＝1+D2+D3，g1(D)＝1+D+D3，当开始进行编码时，8状态子编码器中移位寄存器的初始值为0，编码结构如图10所示。Turbo编码器输出为：
Figure PCTCN2017080294-appb-000003
其中，k＝0,1,2,…,K-1。
输入Turbo编码器的比特表示为c0,c1,c2,c3,…,cK-1，第一个和第二个8状态子编码器的输出比特分别为z0,z1,z2,z3,…,zK-1和z′0，z′1,z′2,z′3,…,z′K-1。从Turbo码内交织器的输出比特表示为c′0,c′1,…,c′K-1，这些比特将输入第二个8状态子编码器。

实例2
本实例与实例1的区别在于：重传数据的比特数目不同，当基站700向车载***701发送完首传数据后，接收车载***701的反馈信息，若反馈信 息指示数据接收错误，所述数据混合重传方法包括如下所述：
确定重传数据比特数目，其中，所述重传数据比特数目等于调制阶数和预设资源数目的乘积，设***设定的调制方式为16QAM(调制阶数M＝4)，重传数据的***预设资源为1500个星座符号，即可以计算出重传数据的比特数目等于6000；
根据重传数据比特数目6000，从第一数据集合和第二数据集合中进行比特选择获得所述重传数据。由于首传数据中原始包中的每份数据包(Turbo编码块)已经传输了864比特，为了使得重传数据中的原始包中每份数据包以及校验包的比特数目基本相等(每份数据包和校验包中各自总传输比特数目的差值在5比特以内，所述总传输比特数目是指所有已经传输的比特，包括首传数据和重传数据)，则从第一数据集合中多选择864比特，剩余比特数目由d＝10份数据包和1份校验包平均分配，即重传数据中的速率匹配后的10份数据包的比特数目计算如下：有d1＝10份数据包的比特数目为N1＝707，d-d1＝0份数据包的比特数目为N1-1＝706，
Figure PCTCN2017080294-appb-000042
d1＝mod(N-n,N1-1)＝10，以及重传数据中的校验包的比特数目为N-d1×N1-(d-d1)×(N1-1)＝1570，其中，N为重传数据比特数目6000，n是首传数据中的任一份数据包的比特数目864，按该比特数目从第一数据集合和第二数据集合进行比特选择可以获得比特数目为6000比特的重传数据。所述比特选择的起始比特索引位置可以由传输版本号rvidx、子块交织的行数

Turbo编码块软缓存的比特长度Ncb确定，该方法如实例1所述，这里不再赘述；或者可以按顺序方式进行比特选择，例如，若上次选择的最末的索引位置为y，则本次比特选择的起始比特索引位置为y+1，并且当从数据中选择到尾比特时则从首比特继续选择，直到收集完所需要的比特数目。
对以上比特选择输出的6000比特的重传数据进行16QAM调制，可以获得1500个星座调制符号，发送所述调制后的星座符号。
实例3
本实例与实例1的区别在于，所述第一数据集合的定义不同，所述第一数据集合包括校验包的所有比特，而第二数据集合只包括原始包的所有校验比特。重传数据的比特数目和实例1的相同，比特选择按顺序方式进行循环 选择。
或者，所述第一数据集合包括校验包的所有***比特，第二数据集合包括原始包的校验比特和校验包的校验比特，此时所述预设正整数N0等于校验包中的***比特数目432的i倍，其中，i是重传次数，如果是第1(或2或3)次重传则i＝1(或2或3)。如果第1次重传数据的比特数目为432，从第一数据集合中选择432比特，由于第一数据集合只包含校验包***比特且其比特数目正好等于432比特，该比特选择得到的432比特就是所有第一数据集合中的所有比特；若第2次重传数据的比特数目为600(该值可以是由***预设，或者接收端反馈信息指示，或者由可分配资源所确定)，其值小于432×2，所以还是从第一数据集合中进行选择；其他依次类推操作可以获得相应比特的重传数据。
或者，所述第一数据集合包括校验包的所有***比特，第二数据集合包括原始包的所有比特。或者，所述第一数据集合包括校验包的所有***比特，第二数据集合包括原始包的校验比特。所述的比特选择方法与以上所述方法类似，这里不再赘述。

是第i次重传数据中第j个Turbo编码块软信息，LLRj是软数据合并后的第j个Turbo编码块的软数据，j＝0,1,…,9，以及校验包软数据也是按相同处理方法进行合并获得；然后再对所述10份解速率匹配后的Turbo编码块软信息和校验包软信息进行解码，获得源数据包，由于校验包是所有Turbo编码块的异或结果(单奇偶校验编码)，所以所述校验包也属于所述的Turbo码字空间，也可以进行Turbo译码，所述解码方法可以采用以下所述步骤(迭代方法)进行：1、先对d＝10份Turbo编码块软信息和校 验包软信息进行Turbo译码；2、对Turbo译码进行判决，保留译码错误的Turbo编码块软信息，如果译码正确或者达到最大迭代次数(最大为5次)则退出迭代；3、通过包编码译码对译码错误的Turbo编码块软信息进行修正，返回第1步骤；并通过循环冗余校验序列(CRC序列)和Turbo码字空间中至少一项对解码结果进行判决(所述判决方法不限于以上所述方法)，如果所有Turbo码解码结果正确，则向发送端反馈信息ACK指示正确接收；如果解码结果有错误，当Turbo码错误数目与总Turbo码块数目的比值小于或等于T时，则反馈NACK1，指示重传864比特的重传数据，而当Turbo码错误数目与总Turbo码块数目的比值大于T时，则反馈NACK2，指示重传8640比特的重传数据，其中，所述的预设阈值T是大于0且小于1的实数，在本实例中，T等于0.9。

依据以上所述的传输数据，本实例提供一种数据混合重传处理方法，用于数据接收侧(下行时是移动用户，上行时是基站)，包括以下步骤：
1，接收发送端的传输数据；对接收到的10752个星座符号进行解调，获得21504个软信息值(对数似然比)，划分为16份数目都为1344的软信息块(8份软数据包，每份软数据包包括2份软信息块)，进行解速率匹配获得相应的Turbo码软数据块。
2，对接收到的传输数据进行解码；对所述解速率匹配后的16份软信息块进行Turbo解码，获得16份解码信息块，即得到8份解码数据包，所述每份解码数据包中有2份解码信息块。
3，通过CRC序列和是否属于Turbo码码字空间等方式中至少一项判决 所述接收到的8份解码数据包的正确性。若所述解码结果错误，向发送端发送反馈信息，由所述反馈信息和首传数据确定重传数据比特数目，选择以下方式之一获得所述重传数据：a、所述重传数据从第一数据集合中选择；b、所述重传数据从第二数据集合和第一数据集合中至少一项选择；其中，所述第一数据集合是至少包括校验包***比特的比特集合，所述第二数据集合是至少包括原始包校验比特的比特集合，原始包包含多份数据包，所述校验包是对所述原始包进行包编码获得。
所述包编码中，若校验编码采用单奇偶校验编码，即所述校验包只包含1个子校验包。即，校验包为可以表示为P0＝S0⊕S1⊕…⊕S7，其中，P0是校验包，S0,S1,…,S7是所述原始包中d＝8份数据包，每份数据包的比特数目为6072，包含2份Turbo编码块。如图15所示，校验包1501的***比特由8份数据包(S0,S1,…,S7)的***比特进行单奇偶校验编码获得，校验包1501的校验比特由8份数据包(S0,S1,…,S7)1500的校验比特进行单奇偶校验编码获得，每份数据包的***比特由属于该数据包的所有Turbo编码块的***比特构成，而原始包***比特是所有数据包的***比特构成，每份数据包的校验比特由属于该数据包的所有Turbo编码块的校验比特构成，原始包校验比特是所有数据包的校验比特构成。
步骤3中，若所述接收的传输数据误码块率大于T(i-1)且小于Ti，发送反馈信息i，用于指示重传数据比特数目等于Di；其中，Ti是预设阈值集合的第i个元素，且0<T(i-1)<Ti，i＝[2,3,4]，反馈信息i是反馈信息集合中第i个元素，Di是预设重传数据比特数目集合中第i个元素，Di是大于0的整数，且D(i-1)<Di；所述接收的传输数据误码块率是所述接收传输数据中的误码块数与所述接收传输数据中所***块数的比值。在本实例中，预设阈值集合为[0 0.2 0.4 0.7 1]，反馈信息集合为[ACK,NACK0,NACK1,NACK2,NACK3]，预设重传数据比特数目集合为[0,2688,8000,16000,21504]。如果所述接收的传输数据误码块率等于T0(即等于0)，发送反馈信息0(即ACK)，指示重传数据比特数目等于D0(即等于0)。
在步骤3中，包括：若所述接收的传输数据正确，则反馈信息0(ACK)，指示正确接收；若所述接收的传输数据的误码块率大于0且小于T，发送反 馈信息1(NACK1)，指示重传数据比特数目等于首传数据中的任一份数据包比特数目，即等于2688；若所述接收的传输数据的误码块率大于或等于T，发送反馈信息2(NACK2)，指示重传数据比特数目等于首传数据的比特数目，即等于21504；其中，T＝0.9，误码块率是所述接收传输数据中的错误Turbo码块数与所述接收传输数据中的所有Turbo码块数(等于16)的比值。
或者，所述在步骤3中，可以包括：若所述接收的传输数据正确，则反馈信息0(ACK)，指示正确接收；若所述接收的传输数据的误码块率大于0且小于T0，发送反馈信息1(NACK1)，指示重传数据比特数目等于首传数据中的任一份数据包比特数目，即等于2688；若所述接收的传输数据的误码块率大于或等于T0且小于T1，发送反馈信2(NACK2)，指示重传数据比特数目等于Q0＝15000；若所述接收的传输数据的误码块率大于或等于T1，发送反馈信息3(NACK3)，指示重传数据比特数目等于首传数据的比特数目，即等于21504；其中，T0＝0.3，T1＝0.6，误码块率是所述接收传输数据中的错误Turbo码块数与所有Turbo码块数(等于16)的比值。

本实例与实例1至实例5的区别在于信道编码方式，所用信道编码方法是LDPC编码，或者Polar编码，或者卷积编码。
LDPC码的全称是低密度奇偶校验码(Low Density Parity Check Code，LDPC)，它是由Robert G.Gallager博士于1963年提出的一类具有稀疏校验矩阵的线性分组码，不仅有逼近Shannon限的良好性能，而且译码复杂度较低，结构灵活，目前已广泛应用于深空通信、光纤通信、卫星数字视频和音频广播等领域。结构化LDPC码是由大小为(mb×z)×(nb×z)的奇偶校验矩阵H定义，其中，奇偶校验矩阵H是由大小为mb×nb的基础矩阵Hb、扩展因子z和基本置换矩阵P三个变量确定。信息序列长度k＝(nb-mb)×z，码字长度n＝nb×z，码率r＝k/n。基础矩阵Hb中所有元素置换成全0方阵或者基本置换矩阵P的hbij次幂矩阵得到扩展后奇偶校验矩阵H，其中hbij是Hb中的元素。基础矩阵Hb的定义如下，

Figure PCTCN2017080294-appb-000049
以上介绍的LDPC码是二元域上的编码，还包括多元域的LDPC编码，假设在域GF(2)(二元域)和域GF(q)(q＝2p)上构造的LDCP码所对应的校验矩阵分别是H2和Hq。H2中的元素是0或1，而Hq是由元素0,1,…,q-1构成，Hq中的每个元素都是H2中p个元素的合成。如果设域GF(q)(q＝2p)上的一个值a与一个1×p的二进制向量相关联，那么把这个向量代入Hq中，就可以得到Hq的二进制表示。对比于二元域LDPC码，多元域LDPC的二分图结构并没有改变，不会造成节点之间短圈数目的增加，从而使得译码性能得到显著的提高。这种多元域上的编码构造会增加译码复杂度，但是相对于译码性能的提高来说这种增加是值得的。LDPC码的译码算法包括以下三大类：硬判决译码、软判决译码和混合译码。硬判决译码将接收的实数序列先进行硬判决，最后将得到的硬判决序列输送到硬判决译码器进行译码。软判决译码可以充分利用接收的信道信息(软信息)，信道信息利用率得到了极大的提高，可以获得出色的误码性能。混合译码结合了软判决译码和硬判决译码的特点。
极化码(Polar Code)具有确定的构造方法，并且是第一种、也是已知的唯一一种能够被严格证明“达到”信道容量的信道编码方法。对N＝2n个独立的二进制输入信道W，其中n为自然数。进行所谓的信道合并操作和信道分割操作，从而得到N个前后依赖的极化信道。这些极化信道相比原本未经极化的信道，在和容量保持不变的情况下，容量会呈现出极化现象：一部分信道的容量增大，另一部分信道的容量减小。并且，理论上已经证明，对接近无穷多个信道进行极化操作后，即N趋向于无穷大时，一部分信道的容量将会趋于1，而其余信道的容量将趋于0，同时，容量为1的信道占信道总数的比例正好为原二进制输入离散信道的容量。这一现象被称为信道极化(Channel Polarization)。在信道极化的基础上，只需要在一部分容量趋于1的信道上传输承载信息的自由比特，而在剩下的容量趋于1的信道以及容量趋于0的信道上传输对收发端都一直的固定比特。用K表示用于传输自由比特的信道数，由此形成了一个由K个信息比特到N个发送比特的一一映射关系，这一映射即是极化编码。在译码端，根据信道极化时引入的每个比特之间的依赖关系，使用一种称为串行抵消(SC)的算法进行译码，编码译码复杂度均为O(NlogN)。本实例中所采用的Polar码为：在一信道中传输一个比特数目为K0的信息序列，则只需要从N0个极化信道中选择具有最小错误概率值的K0个用以传输信息序列，将这部分极化信道称为信息信道，其余的信道则传输一些接收端和发送端约定确知的固定序列，所述固定序列常常设定为全零序列，将该部分信道称为固定信道。当信息信道和固定序列的固定信道确定后，由于信息序列的数目为K0，而实际通过信道的N0个时隙发送了N0个信息，可以看成一个从K0维空间到N0维空间的映射，该映射就是极化编码，码率为R0＝K0/N0。所述极化码中，极化码***比特是指：编码后所有N0比特的极化编码块中的K0比特。其中，所述K0比特是从第R1比特开始的顺序K0比特，如果到达尾比特还不足K0比特，则继续从首比特顺序开始，其中R1是大于或者等于0的整数；或者所述极化编码块的N0比特中，按影响度的大小进行大到小排列，最前的K0比特就是***比特，所述的影响度大小是指与极化编码块中第i比特相关联的J比特，如图20所示是极化编码的一个示例，如果码率为1/2，则从输入端

在卷积码的编码过程中，对输入信息比特进行组编码，每个码组的编码输出比特不仅与该分组的信息比特有关，还与前面时刻的其他分组的信息比特有关。以及，在卷积码的译码过程中，不仅可以从当前时刻收到的分组中获取译码信息，还要从前后关联的分组中提取相关信息。正是由于在卷积码的编码过程中充分利用了各组的相关性，使得卷积码具有相当好的性能增益。本实例中，所述卷积码采用LTE***中定义的咬尾卷积编码方法，约束长度为7、码率为1/3的咬尾卷积编码如图12所示。编码器的移位寄存器的初始值设置为输入流最后的6个信息比特对应的值，使得移位寄存器的初始和最终状态相同。因此，用s0,s1,s2,...,s5表示编码器的移位寄存器，那么移位寄存器初始值被设置为：si＝c(K-1-i)。编码器的输出流

根据本申请的一个方面，用于LTE移动通信***或者未来第五代移动通信***，数据传输方向为基站向移动用户发送数据(下行传输业务数据)，或者数据传输方向为移动用户向基站发送数据(上行传输业务数据)。所述移动用户包括：移动设备、为接入终端、用户终端、用户站、用户单元、移动站、远程站、远程终端、用户代理、用户装置、用户设备、或一些其它术语。所述基站包括接入点(AP)、或可以称为节点B(node B)、无线电网络控制器(RNC)、演进型Node B(Evolved Node B，eNB)、基站控制器(BSC)、基站收发台(BTS)、基站(BS)、收发机功能体(TF)、无线电路由器、无线电收发机、基本服务单元(BSS)、扩展服务单元(ESS)、无线电基站(RBS)，或一些其它术语。
根据本申请的一个方面，本实例提供一种数据传输处理方法，用于发送端，处理的源数据包如下：源数据包的比特数目为3968，CRC序列比特数目为I＝16比特，调制方式为QPSK，调制阶数为2，编码码率为1/2。处理步骤 包括以下：
1、对源数据包进行分割获得H1＝8份子数据块，每份子数据块的比特数目为496比特；
2、对所述H1＝8份子数据块分别添加长度为I＝16比特的CRC序列，获得比特数目都为512的添加CRC序列后的子数据块；
3、对所述添加CRC序列后的H1＝8份子数据块分别进行极化编码获得H1＝8份极化编码块；
4、对所述H1＝8份极化编码块的全部比特或者部分比特进行包编码获得H2＝1份子校验包，所述H1＝8份极化编码块和所述H2＝1份子校验包构成首传数据。
一个长度为N＝1024的向量μN经过生成矩阵为GN的Polar码编码后得到一个长度为N的向量xN：
xN＝μNGN
其中，生成矩阵GN满足下式：

F为F2的n次Kronecker幂，且F2由下式得到：

而BN是比特翻转置换矩阵。假如

那么元素
Figure PCTCN2017080294-appb-000057
等于元素μbn…b2b1，其中，b1，...，bn为0或者1，b1b2…bn以及bn…b2b1为二进制数表达的下标。编码过程为依据输出比特(小于或等于1024)对信道参数进行极化分解(高斯近似等算法)获得1024个输入的可靠性值，依据可靠性高低从向量μN中选择最高的512输入端等于每份添加CRC序列后子数据块的512比特，则可以获得一组1024比特的输出比特，即为极化编码块。
在本实例中，在步骤4中，对所述H1＝8份极化编码块的最前512比特(即等于***比特数目，即子数据块比特数目加CRC序列比特数目)进行包编码获得H2＝1份比特数目为512比特的子校验包，P0＝S’0⊕S’1⊕…⊕S’7， S’0～S’7分别对应极化编码块S0～S7中的最前512比特。由于校验包长度为512比特，则为了使得总传输数据码率等于1/2，所以每个极化编码块的比特数目为1024-512/8＝960比特。在极化编码过程中，需要确定为最前64输出端口为不用端口，通过对后960输出端口进行信道极化计算每个输入端口的可靠性，依据可靠性大小排序，然后将每份添加CRC后的子数据块输入相应输入端口，即可获得对应极化编码块，比特数目都为960。包编码有利于将所有极化编码块联系起来，在接收端可以利用该关系进行译码或者迭代译码，每个极化编码块可以利用其它编码块的信息进行更新，可以极大的获得编码增益，即采用简单编码方法将短码块构造成一个信道编码块，进而获得码长增益，并且由于只是简单的异或关系，接收端的译码复杂度并不大。
所述极化编码后的H1＝8份比特数目为960的极化编码块和H2＝1份比特数目为512的校验包构成首传数据，所述首传数据的比特数目为8192，对其进行QPSK调制获得4096个星座符号，发送所述4096个星座符号。
