图1是本发明实施例的传输数据的方法的示意性流程图。图1的方法包括:
110、发送端根据待传输数据的传输块的大小、所述待传输数据采用的基础参数集以及所述待传输数据的业务类型中的至少一种确定所述待传输数据的信道编码方式。
应理解，上述传输块是承载上述待传输数据的传输块，传输块的大小是传输块大小(TBSize)。承载待传输数据的传输块可以是一个也可以是多个。此外，待传输数据的传输块的大小、待传输数据采用的基础参数集以及待传输数据的业务类型可以认为是待传输数据的特征信息。利用待传输数据的特征信息可以为待传输数据选择合适的信道调制方式。
120、发送端以待传输数据的信道编码方式对所述待传输数据进行信道编码。
例如，在步骤110中发送端确定待传输数据的信道编码方式为Polar编码，那么在步骤120中发送端就以Polar编码对待传输数据进行信道编码。
130、所述发送端向接收端发送信道编码后的所述待传输数据。
应理解，本发明实施例中的发送端和接收端均可以是网络侧设备或者终端设备，较为常见的情形是发送端为网络侧设备，接收端为终端设备，或者，发送端和接收端均为终端设备。
本发明实施例中的网络侧设备可以是用于与终端设备通信的设备，该网络侧设备可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional NodeB，eNB或eNodeB)，还可以是云无线接入网络(Cloud Radio Access Network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络侧设备或者未来演进的PLMN网络中的网络侧设备等，本发明实施例并不限定。

本发明实施例中，根据待传输数据的传输块大小、待传输数据采用的基础参数集以及待传输数据的业务类型中的至少一种来确定待传输数据的信道编码方式，与LTE系统中采用单一的信道编码方式相比，能够根据待传输数据的特征信息为待传输数据选择合适的信道编码方式。
可选地，作为一个实施例，发送端根据待传输数据的传输块的大小，以及传输块的大小与信道编码方式的对应关系，确定所述待传输数据的信道编码方式。其中，传输块的大小与信道编码方式的对应关系可以是预先设定好的。
应理解，待传输数据的传输块的大小可以根据调度待传输数据的控制信令中包含的调制与编码策略(Modulation and Coding Scheme，MCS)指示信息来确定。具体而言，待传输数据的数据块大小可以根据MCS指示信息所 指示的MCS以及待传输数据的频域资源大小(该频域资源大小可以由调度待传输数据的频域资源配置信息来确定)来确定。其中，MCS和频域资源大小两者与传输块大小的对应关系可以由发送端和接收端预先约定好，这样，发送端和接收端就可以直接根据MCS和待传输数据的频域资源大小来确定待传输数据的传输块大小了。另外，还可以直接根据MCS与传输块的大小来确定待传输数据的传输块大小。
发送端在根据待传输数据的传输块的大小，以及传输块的大小与信道编码方式的对应关系，确定所述待传输数据的信道编码方式时可以采用以下两种方式：
方式一：
发送端根据待传输数据的第一传输块的大小，以及传输块的大小与信道编码方式的对应关系，确定第一传输块的信道编码方式。应理解，确定第一传输块的信道编码方式是指确定第一传输块承载的数据的编码方式，接下来，发送端会根据第一传输块承载的数据的编码方式对第一传输块承载的数据进行信道编码。上述第一传输块可以是待传输数据的任意一个传输块，也可以是待传输数据中的某个特定的传输块。
当上述第一传输块是待传输数据的任意一个传输块时，例如，待传输的数据包括两个传输块，那么就可以根据方式一分别确定这两个传输块各自对应的信道编码方式。也就是说，在方式一中，可以确定各个传输块的信道编码方式，然后再根据确定的信道编码方式分别对各个传输块进行信道编码。
具体地，假设待传输数据包含两个传输块，分别是传输块1和传输块2，当传输块1的大小小于或者等于预设的第一阈值时，确定传输块1的信道编码方式为Polar编码，当传输块1的大小大于预设的第一阈值时，确定传输块1的信道编码方式为Turbo编码。同样，对于传输块2，当传输块2的大小小于或者等于预设的第一阈值时，确定传输块2的信道编码方式为Polar编码，当传输块2的大小大于预设的第一阈值时，确定传输块2的信道编码方式为Turbo编码。假设经过判断之后发现传输块1的大小小于预设的第一阈值，而传输块2的大小大于预设的第一阈值，那么就确定传输块1的信道编码方式为Polar编码，传输块2的信道编码方式为Turbo编码。
当上述第一传输块是待传输数据的某个特定的传输块时，例如，待传输数据包含传输块1和其它的传输块，其中，传输块1是第一传输块，那么可 以根据方式一来确定传输块1的信道编码方式，而对于其它的传输块既可以采用方式一来确定信道编码方式，也可以采用别的方式或方法来确定信道编码方式。
方式二：
发送端根据待传输数据的第二传输块的大小，以及传输块的大小与信道编码方式的对应关系，确定待传输数据的所有传输块的信道编码方式。
在方式二中，发送端是根据待传输数据的所有传输块中的一个传输块来确定待传输数据的所有传输块的信道编码方式，也就是根据一个传输块来确定信道编码方式，并将该信道编码方式作为待传输数据的全部传输块的信道编码方式，相对于方式一中要确定待传输数据的各个传输块的编码方式，并且在信道编码时对各个传输块要采用不同的编码方式相比，方式二降低了实现了复杂度，简化了确定信道编码方式的流程和步骤。
可选地，上述第二传输块可以是待传输数据中特定的传输块，也可以是待传输数据的所有传输块中的最大传输块或者最小传输块。
当上述第二传输块是待传输数据中的特定传输块时，例如，待传输数据包含多个传输块，该多个传输块中的第一个传输块为第二传输块，那么发送端就可以根据第一个传输块的大小以及传输块大小与信道编码方式的对应关系确定待传输数据的所有传输块的信道编码方式。
当上述第二传输块是待传输数据的所有传输块中的最大传输块或者最小传输块，例如，待传输数据包含多个传输块，其中，传输块1和传输块2分别是待传输数据的最大传输块和最小传输块。那么，可以选择传输块1作为第二传输块，当传输块1的大小小于或者等于预设的第二阈值时，确定待传输数据的所有传输块的信道编码方式均为Polar编码。当传输块1的大小大于预设的第二阈值时，确定待传输数据的所有传输块的信道编码方式均为Turbo编码。
可选地，作为一个实施例，发送端根据待传输数据采用的基础参数集，以及基础参数集中的信息与信道编码方式的对应关系，确定待传输数据的信道编码方式。
上述基础参数集可以包含至少一个能够确定待传输数据的时频资源的资源参数信息，通过该资源参数信息可以确定待传输数据的时频资源，进而根据待传输数据的时频资源来确定待传输数据的信道编码方式。另外，上述 基础参数集可以由接收端通过信令配置给发送端，或者由发送端根据自身的其他参数(例如，当前的业务类型或者当前的工作频点)得到。另外，对于接收端来说，也可以通过发送端的信令来获取该基础参数集，也可以根据自身的其他参数得到该基础参数集。或者，发送端和接收端可以通过预先配置来获取待传输数据采用的基础参数集。
上述基础参数集可以包含下列信息中的至少一种：子载波间隔；预设带宽下的子载波数目；物理资源块(Physical Resource Block，PRB)包含的子载波数目；正交频分复用(Orthogonal Frequency Division Multiplex，OFDM)符号长度；傅立叶变换或者傅立叶逆变换生成OFDM信号所使用的点数；每个传输时间间隔(Transmission Time Interval，TTI)包含的OFDM符号数目；预设时间单位内包含的TTI数目；信号前缀信息。
其中，子载波间隔是相邻子载波的频率间隔，例如，子载波间隔可以为15Khz，60Khz等；预设带宽下的子载波数目是指每个可能的系统带宽下对应子载波的数目；典型地，PRB中包含的子载波的数目是6或12的整数倍，例如，12、24等；生成OFDM符号时傅里叶变换或者傅里叶逆变换使用的点数一般是2的整数次幂，这里的傅里叶变换可以是快速傅里叶变换(Fast Fourier Transform，FFT)，傅里叶逆变换可以是快速傅立叶逆变换(Inverse Fast Fourier Transform，IFFT)；每个TTI中包含的OFDM符号的数目可以是2、4、7或者14的整数倍；预设时间单位内包含的TTI的数目可以是1ms或者10ms等一定时间长度内包含的TTI数目；信号前缀信息可以是设备在对数据进行发送或接收时使用的信号的信号前缀信息，它可以包含信号的循环前缀的时间长度，循环前缀使用常规循环前缀还是扩展循环前缀。
当上述基础参数集包含子载波间隔信息时，发送端可以根据待传输数据采用的子载波间隔大小，以及子载波间隔大小与信道编码方式的对应关系(该预设关系可以是预先设置的)确定待传输数据的信道编码方式。
例如，当待传输数据的子载波间隔为15Khz时，确定待传输数据的信道编码方式为尾位卷积码(Tail-Biting Convolutional Coding，TBCC)编码，当待传输数据的子载波间隔为60Khz时，确定待传输数据的信道编码方式为低密度奇偶校验(Low-Density Parity Check，LDPC)编码。
当上述基础参数集包含每个TTI包含的OFDM符号数信息时，发送端 可以根据待传输数据对应的TTI包含的OFDM符号数，以及OFDM符号数与信道编码方式的对应关系(该预设关系可以是预先设置的)来确定待传输数据的信道编码方式。
例如，当待传输数据的每个TTI包含的OFDM符号数小于预设的第三阈值时，确定待传输数据的信道编码方式为Turbo编码，当待传输数据的每个TTI包含的OFDM符号数小于预设的第三阈值时，确定待传输数据的信道编码方式为Polar编码。
应理解，上述基础参数集中的信息与信道编码方式的对应关系可以是基础参数集中的一种信息与信道编码方式的对应关系，也可以是基础参数集中的多种信息共同与信道编码方式的对应关系。
也就是说，发送端可以根据基础参数集中的一种信息，以及该信息与信道编码方式的对应关系来确定待传输数据的信道编码方式，例如，发送端还可以根据预设带宽下的子载波数目、以及预设带宽下的子载波数目与信道编码方式的对应关系来确定待传输数据的信道编码方式。此外，发送端也可以根据基础参数集中的多种信息，以及该多种信息与信道编码方式的对应关系来确定待传输数据的信道编码方式，例如，发送端可以根据子载波间隔和每个TTI包含的OFDM符号数，以及子载波间隔和每个TTI包含的OFDM符号数两者与信道编码方式的对应关系来确定待传输数据的信道编码方式。具体来说，当待传输数据的子载波间隔为15Khz，并且每个TTI包含的OFDM符号数小于预设的第三阈值时，确定待传输数据的信道编码方式为Turbo编码；当待传输数据的子载波间隔为60Khz，并且每个TTI包含的OFDM符号数大于预设的第三阈值时，确定待传输数据的信道编码方式为TBCC编码。
可选地，作为一个实施例，发送端根据待传输数据的业务类型，以及业务类型与信道编码方式的对应关系确定待传输数据的信道编码方式。
上述待传输数据的业务类型可以包括LTE数据、增强移动宽带(enhanced Mobile Broadband，eMBB)、超可靠超低延时通信(Ultra-Reliable and Low Latency Communications，URLLC)以及大规模机器通信(massive Machine Type Communications，mMTC)中的任意一种。
具体而言，当待传输数据的业务类型为LTE数据时，待传输数据的信道编码方式为Turbo编码，当待传输数据的业务类型为eMBB或者URLLC时， 待传输数据的信道编码方式为LDPC编码，当待传输数据的业务类型为mMTC时，待传输数据的信道编码方式为TBCC编码。
根据业务类型选择相应的信道编码方式，能够为不同的业务类型选择解码复杂度、解调性能等最佳的信道编码方式。
应理解，本发明实施例中除了可以根据待传输数据的传输块的大小、待传输数据采用的基础参数集以及待传输数据的业务类型中的一种来确定待传输数据的信道编码方式之外，还可以根据待传输数据的传输块的大小、待传输数据采用的基础参数集以及待传输数据的业务类型中的多种来确定待传输数据的信道编码方式。例如，发送端可以根据待传输数据的传输块大小以及待传输数据的业务类型两者与信道编码方式的对应关系确定待传输数据的信道编码方式，具体地，当待传输数据的业务类型为eMBB并且待传输数据的传输块大小小于预设的第四阈值时，确定待传输数据的信道编码方式为LDPC编码，当待传输数据的业务类型为mMTC并且待传输数据的传输块大小大于预设的第四阈值时，确定待传输数据的信道编码方式为TBCC编码。
上文结合图1，从发送端的角度详细描述了本发明实施例的传输数据的方法，下文结合图2，从接收端的角度描述本发明实施例的传输数据的方法。应理解，发送端与接收端的描述相互对应，因此图2中未详细描述的部分可以参见图1的实施例。
图2是本发明实施例的传输数据的方法的示意性流程图。图2的方法包括:
210、接收端接收发送端发送的第一数据；
220、所述接收端根据所述第一数据的传输块的大小、所述第一数据采用的基础参数集以及所述第一数据的业务类型中的至少一种确定所述第一数据的信道编码方式；
230、所述接收端基于所述第一数据的信道编码方式对应的信道解码方式对所述第一数据进行信道解码。
应理解，接收端在接收到第一数据后可以先确定第一数据的信道编码方式，然后再采用第一数据的信道编码方式对应的信道解码方式对第一数据进行信道解码。接收端也可以在接收到第一数据后直接确定第一数据的信道解码方式，然后以该信道解码方式对第一数据进行信道解码。
此外，本发明实施例中的发送端和接收端均可以是网络侧设备或者终端设备，较为常见的情形是发送端为网络侧设备，接收端为终端设备，或者，发送端和接收端均为终端设备。
本发明实施例中，根据待传输数据的传输块大小、待传输数据采用的基础参数集以及待传输数据的业务类型中的至少一种来确定待传输数据的信道编码方式，与LTE系统中采用单一的信道编码方式相比，能够根据待传输数据的特征信息为待传输数据选择合适的信道编码方式。
可选地，作为一个实施例，所述接收端根据所述第一数据的传输块的大小，以及传输块的大小与信道编码方式的对应关系，确定所述第一数据的信道编码方式。

可选地，作为一个实施例，所述接收端根据所述第一数据的业务类型，以及业务类型与信道编码方式的对应关系确定所述第一数据的信道编码方式。
可选地，作为一个实施例，所述第一数据的业务类型为LTE数据、eMBB、 URLLC以及mMTC中的任意一种。
可选地，作为一个实施例，所述信道编码方式为下列方式中的任意一种：低密度奇偶校验LDPC编码；Turbo编码；Polar编码；尾位卷积码TBCC编码；瑞德-米勒RM编码。
下面以网络侧设备向终端设备发送数据为例对本发明实施例的传输数据的方法进行详细的描述。
301、网络侧设备确定待传输数据所用的传输块的传输块大小。
在确定待传输数据的传输块的传输块大小时可以根据信道质量和待传输数据的业务类型来确定，也可以根据MCS以及待传输数据的频域资源大小来确定。
302、网络侧设备根据待传输数据的各个传输块的传输块大小，确定各个传输块的信道编码方式。
例如，待传输数据包含两个传输块，分别是第一传输块和第二传输块，其中，第一传输块的大小小于500比特，第二传输块的大小大于500比特，那么第一传输块的信道编码方式为LDPC编码，第二传输块的信道编码方式为Turbo编码。
303、网络侧设备通过下行控制信息(Downlink Control Information，DCI)向终端设备发送调度信令。
304、网络侧设备向终端设备发送信道编码后的待传输数据。
应理解，步骤303和步骤304可以同时发生，也就是说网络侧设备可以向终端设备同时发送调度信令以及信道编码后的待传输数据，另外，网络侧设备还可以先向终端设备发送调度信令再向终端设备发送信道编码后的待传输数据。
305、终端设备接收到网络侧设备发送的调度信令后，根据调度信令中的MCS指示信息以及频域资源配置信息确定待传输数据所用的传输块的传输块大小。
例如，一个MCS索引值和一个频域资源大小共同对应一个传输块大小，并且，它们之间的对应关系由网络侧设备和终端设备预先约定好，那么，网络侧设备和终端设备就可以根据MCS索引值以及频域资源大小共同确定待传输数据的传输块的大小。
306、终端设备根据待传输数据的各个传输块的传输块大小，确定各个 传输块的信道编码方式。
例如，待传输数据包含两个传输块，分别是第一传输块和第二传输块，其中，第一传输块的大小小于500比特，第二传输块的大小大于500比特，那么第一传输块的信道编码方式为LDPC编码，第二传输块的信道编码方式为Turbo编码。
307、终端设备在接收到网络侧设备的调度信令后，根据该调度信令检测网络侧设备发送的编码后的待传输数据，并基于步骤305中确定的各个传输块的信道编码方式对应的信道解码方式对待传输数据的各个传输块进行信道解码。
上述步骤301-307以网络侧设备向终端设备发送数据(下行数据传输)为例对本发明实施例的传输数据的方法进行了描述，下面以终端设备向网络侧设备发送数据(上行数据传输)为例对本发明实施例的传输数据的方法进行详细的描述。具体步骤如下：
401、网络侧设备确定终端设备在进行数据传输时的一个TTI中所包含的OFDM符号数目。
具体来说，网络侧设备可以根据终端设备发送待传输数据的业务类型来确定一个TTI中包含的OFDM符号数。
402、网络侧设备通过DCI向终端设备发送调度信令，调度终端设备进行上行数据的传输。
该调度信令中包含终端设备在进行上行数据传输时一个TTI中包含的OFDM符号数的指示信息，根据该指示信息终端设备可以获知一个TTI中包含的OFDM符号数。
403、终端设备在接收到网络侧设备发送的调度信令后，根据调度信令中的指示信息确定一个TTI中包含的OFDM符号数。
404、终端设备根据一个TTI中包含的OFDM符号数确定待传输的数据的信道编码方式。
例如，当一个TTI中的OFDM符号数小于4时，确定待传输的数据的信道编码方式为TBCC编码，当一个TTI中的OFDM符号数小于或等于4并且小于14时，确定待传输的数据的信道编码方式为Turbo编码，当一个TTI中的OFDM符号数大于14时，确定待传输的数据的信道编码方式为Polar编码。
405、终端设备基于步骤404中确定的信道编码方式对待传输的数据进行信道编码。
406、终端设备根据网络设备的调度信令将信道编码后的待传输数据发送给网络侧设备。
407、网络侧设备根据一个TTI中包含的OFDM符号数确定终端设备对待传输数据进行信道编码时采用的信道编码方式。
408、网络侧设备根据待传输数据的信道编码方式对应的信道解码方式对终端设备发送的信道编码后的待传输数据进行信道解码。
上文结合图1和图2详细的描述了本发明实施例的传输数据的方法，下面结合图3至图6，详细描述本发明实施例的传输数据的设备。应理解，图3至图6中的传输数据的设备能够执行上文中由发送端和接收端执行的各个步骤，为了避免重复，此处不再详述。
