具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开实施方式作进一步地详细描述。
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
窄带物联网(英文：narrow band Internet of things；简称：NB-IoT)以及机器类通信(英文：machine type communication；简称：MTC)是两种主要针对低功耗广覆盖(英文：low power wide area；简称：LPWA)类通信业务的物联网技术。
为了增强覆盖能力，NB-IoT和MTC中都引入了重复发送的机制，在重复发送的机制中，对于某一上行数据，用户设备(英文：User Equipment；简称：UE)需要向基站重复多次发送该上行数据。其中，覆盖能力通常可以使用最大耦合路损(英文：maximum coupling loss；简称：MCL)来进行表征，NB-IoT的MLC可以达到164db，MTC的MCL可以达到155.7db。
此外，为了减小传输时延，NB-IoT和MTC都可以支持数据提前传输(英文：early data transmission；简称：EDT)技术，在EDT技术中，UE可以在随机接入的过程中传输上行数据。
当前，如何在EDT技术中引入重复发送的机制，也即是，如何在EDT技术中使UE向基站重复发送上行数据已经成为了一个亟待解决的问题。
本公开实施例提供了一种数据传输方法，该数据传输方法可以解决EDT技术中UE如何向基站重复发送上行数据的问题，在该数据传输方法中，基站可以通过目标随机接入响应向UE发送重复次数指示信息，UE可以基于该重复次数指示信息和目标传输块大小(英文：transmission block size；简称：TBS)确定目标重复发送次数，其中，该目标重复发送次数即为UE向基站重复发送目标上行数据的次数，该目标上行数据是UE在随机接入过程中发送的上行数据，该目标TBS是UE向基站发送目标上行数据所使用的TBS，而后，UE可 以基于该目标重复发送次数在随机接入的过程中向基站发送目标上行数据，从而实现EDT技术中UE对上行数据的重复发送。
下面，将对本公开实施例提供的数据传输方法所涉及到的实施环境进行说明。
图1为本公开实施例提供的数据传输方法所涉及到的实施环境的示意图，如图1所示，该实施环境可以包括基站10和UE 20，其中，UE 20是基站10所服务的小区中的任意一个UE，基站10和UE 20可以基于NB-IoT通信协议或MTC通信协议进行数据传输。
图2是根据一示例性实施例示出的一种数据传输方法的流程图，如图2所示，该数据传输方法用于图1所示的UE 20中，该数据传输方法包括以下步骤。
步骤201、UE向基站发送目标随机接入前导。
该目标随机接入前导用于指示UE需要在随机接入的过程中向基站发送目标上行数据，换句话说，该目标随机接入前导用于指示UE需要利用EDT技术向基站发送目标上行数据。
步骤202、UE接收基站基于目标随机接入前导发送的目标随机接入响应，该目标随机接入响应携带重复次数指示信息。
步骤203、UE基于目标重复发送次数，在随机接入的过程中向基站发送目标上行数据。
其中，目标重复发送次数是UE在随机接入的过程中向基站重复发送目标上行数据的次数，目标重复发送次数是UE根据重复次数指示信息和目标TBS确定的，该目标TBS是UE在随机接入的过程中向基站发送目标上行数据所使用的TBS。
综上所述，本公开实施例提供的数据传输方法，通过接收基站发送的携带于目标随机接入响应中的重复次数指示信息，并基于目标重复发送次数，在随 机接入的过程中向基站发送目标上行数据，其中，该目标重复发送次数是根据重复发送次数指示信息和目标传输块大小确定的，使得在EDT技术中，用户设备可以向基站重复发送目标上行数据，从而解决了EDT技术中用户设备如何向基站重复发送上行数据的问题。
图3是根据一示例性实施例示出的一种数据传输方法的流程图，如图3所示，该数据传输方法用于图1所示的基站10中，该数据传输方法包括以下步骤。
步骤301、基站接收UE发送的目标随机接入前导。
该目标随机接入前导用于指示UE需要在随机接入的过程中向基站发送目标上行数据，换句话说，该目标随机接入前导用于指示UE需要利用EDT技术向基站发送目标上行数据。
步骤302、基站基于目标随机接入前导向UE发送目标随机接入响应，该目标随机接入响应携带重复次数指示信息。
其中，该重复次数指示信息用于供UE根据该重复次数指数信息和目标TBS确定目标重复发送次数，该目标重复发送次数是UE在随机接入的过程中向基站重复发送目标上行数据的次数，该目标TBS是UE在随机接入的过程中向基站发送目标上行数据所使用的TBS。
步骤303、在随机接入的过程中，基站接收UE基于目标重复发送次数发送的目标上行数据。
综上所述，本公开实施例提供的数据传输方法，通过向用户设备发送携带于目标随机接入响应中的重复次数指示信息，从而使用户设备能够基于目标重复发送次数，在随机接入的过程中向基站发送目标上行数据，其中，该目标重复发送次数是用户设备根据重复发送次数指示信息和目标传输块大小确定的，这样，在EDT技术中，用户设备就可以向基站重复发送目标上行数据，从而解决了EDT技术中用户设备如何向基站重复发送上行数据的问题。
图4是根据一示例性实施例示出的一种数据传输方法的流程图，如图4所示，该数据传输方法用于图1所示的实施环境中，该数据传输方法包括以下步骤。
步骤401、基站广播当前随机接入过程所能传输的最大数据包大小。
在EDT技术中，基站可以根据当前网络的覆盖能力，从通信协议所支持的最大EDT数据包集合中选择一个元素作为当前EDT所支持的最大数据包大小(也即是上文所述的当前随机接入过程所能传输的最大数据包大小)，其中，最大EDT数据包集合包括通信协议所支持的至少一个最大数据包大小。而后，基站可以通过广播的方式向该基站所服务的小区中的UE发送该当前随机接入过程所能传输的最大数据包大小。其中，当前随机接入过程所能传输的最大数据包大小指的是：当前，UE在随机接入过程中能够向基站发送的最大数据量的大小。上述通信协议可以为NB-IoT通信协议或MTC通信协议。
实际实现时，基站选择的最大数据包大小可以与当前网络的覆盖能力正相关，也即是，当前网络的覆盖能力越强，基站选择的最大数据包大小可以越大。通常情况下，通信协议所支持的最大数据包大小可以包括1000bits(中文：比特)、936bits、808bits、680bits、584bits、504bits、408bits和328bits等。
基站除了可以广播当前随机接入过程所能传输的最大数据包大小之外，还可以广播目标上行资源的时频位置，其中，该目标上行资源位于随机接入信道中，该目标上行资源能够承载用于申请在随机接入过程中发送上行数据的随机接入前导(英文：preamble)。
需要指出的是，通常情况下，随机接入前导也可以被称为随机接入过程中的信息1(英文：message 1)。在NB-IoT通信协议中，随机接入信道通常可以被称为NB-IoT物理随机接入信道(英文：Narrow band IoT physical random access channel；简称：NPRACH)。
步骤402、当UE所需传输的数据包的大小不大于当前随机接入过程所能 传输的最大数据包大小时，UE向基站发送目标随机接入前导。
在接收到基站广播的当前随机接入过程所能传输的最大数据包大小之后，UE可以判断自身所需传输的数据包的大小是否大于该当前随机接入过程所能传输的最大数据包大小。
当UE所需传输的数据包的大小大于该当前随机接入过程所能传输的最大数据包大小时，说明UE无法在随机接入过程中发送自身所需传输的数据包。在这种情况下，UE可以进行传统的随机接入，并在随机接入成功之后，向基站发送该UE所需传输的数据包。
当UE所需传输的数据包的大小不大于该当前随机接入过程所能传输的最大数据包大小时，说明UE可以在随机接入过程中发送自身所需传输的数据包。在这种情况下，UE可以基于基站广播的目标上行资源的时频位置确定目标上行资源，并通过该目标上行资源向基站发送目标随机接入前导，其中，该目标随机接入前导用于向基站申请在随机接入过程中发送目标上行数据，换句话说，该目标随机接入前导用于指示UE需要在随机接入的过程中向基站发送目标上行数据，这里所谓的目标上行数据指的就是上文所述的UE所需传输的数据包。
步骤403、在接收到UE发送的目标随机接入前导后，基站基于目标随机接入前导向UE发送目标随机接入响应，该目标随机接入响应携带重复次数指示信息。
在上述目标上行资源上接收到目标随机接入前导后，基站可以确定UE需要在随机接入的过程中发送目标上行数据，在这种情况下，基站可以向UE发送目标随机接入响应(英文：Random Access Response；简称：RAR)，该目标随机接入响应可以携带重复次数指示信息，在本公开的一个实施例中，该目标随机接入响应还可以携带上行资源指示信息。需要指出的是，通常情况下，随机接入响应也可以被称为随机接入过程中的信息2(英文：message 2)。
该上行资源指示信息可以指示基站为UE分配的传输单个目标上行数据所 能使用的上行资源的大小，该上行资源的大小可以由资源单位(英文：resource unit；简称：RU)的个数进行表征。在本公开的一个实施例中，该上行资源指示信息可以携带于目标随机接入响应的上行调度授权(英文：UL grant)中，可选的，该上行资源指示信息可以占据上行调度授权中的调制编码方式域(英文：modulation and coding scheme field)中的3个比特位。
表1为在当前随机接入过程所能传输的最大数据包大小为1000bits时，本公开实施例提供的一种示例性的上行资源指示信息与资源单位(英文：resource unit,简称RU)个数的对应关系。
表1
Figure PCTCN2018086385-appb-000001
如表1所示，在当前随机接入过程所能传输的最大数据包大小为1000bits的情况下，当上行资源指示信息为“011”时，说明基站为UE分配的传输单个目标上行数据所能使用的上行资源为3个RU。
在本公开的一个实施例中，上述重复次数指示信息也可以携带于目标随机接入响应的上行调度授权中，UE可以根据该重复次数指示信息确定UE在随机接入过程中向基站重复发送目标上行数据的次数，其中，UE确定在随机接入过程中向基站重复发送目标上行数据的次数的方式将在下述步骤中进行说明。
步骤404、在接收到基站发送的目标随机接入响应后，UE确定目标TBS。
目标TBS是UE在随机接入过程中向基站发送目标上行数据所使用的TBS。
在接收到基站发送的目标随机接入响应后，UE确定基站允许自身在随机接入的过程中发送目标上行数据。在这种情况下，UE可以根据自身所需传输的数据包的大小(也即是目标上行数据的大小)确定目标TBS，可选的，目标TBS是UE可用的TBS中大于UE所需传输的数据包的大小，且与UE所需传输的数据包的大小相差最小的TBS，例如，在当前随机接入过程所能传输的最大数据包大小为1000bits的情况下，UE可用的TBS共有4个，分别为328bits、536bits、776bits和1000bits，若UE所需传输的数据包的大小为500bits，UE可以将536bits确定为目标TBS。
可选的，UE可以根据基站广播的当前随机接入过程所能传输的最大数据包大小(也即是当前EDT所支持的最大数据包大小)确定UE可用的TBS。表2为本公开实施例提供的一种最大数据包大小与UE可用的TBS的对应关系表。
表2
Figure PCTCN2018086385-appb-000002
在确定了目标TBS之后，UE可以根据上行资源指示信息所指示的RU个数以及目标TBS确定目标上行数据的调制编码方式。通常情况下，在不同的调制编码方式下，每个RU所能承载的数据量的大小不同，例如，当上行资源指示信息所指示的RU个数为4时，也即是，基站为UE分配的传输单个目标上行数据所能使用的上行资源为4个RU时，若UE确定的目标TBS为328bits，则UE可以根据该4个RU以及328bits选择一种调制编码方式，在该调制编码方式下，1个RU所能平均承载的数据量可以为82bits，若UE确定的目标TBS 为1000bits时，UE可以根据该4个RU以及1000bits选择另一种调制编码方式，在该调制编码方式下，1个RU所能平均承载的数据量可以为250bits。
可选的，目标上行数据的调制编码方式可以为正交相移键控(英文：Quadrature Phase Shift Keyin；简称：QPSK)、正交幅度调制(英文：16 Quadrature Amplitude Modulation；简称：16QAM)和相正交振幅调制(英文：64 Quadrature Amplitude Modulation；简称：64QAM)等，本公开实施例对其不做具体限定。
步骤405、UE基于重复次数指示信息和目标TBS确定目标重复发送次数。
目标重复发送次数指的是UE在随机接入过程中向基站重复发送目标上行数据的次数。
通常情况下，在相同的信道条件和资源分配量的情况下，目标重复发送次数受到目标TBS的影响，且与目标TBS正相关，也即是，目标TBS越大，目标重复发送次数也越大，这是因为，目标TBS越大，UE向基站发送目标上行数据的码率也就越大，而在码率较大的情况下，UE需要向基站重复较多次发送该目标上行数据才可以保证基站能够正确接收到该目标上行数据。此外，目标重复发送次数还受到当前信道质量的影响，且与当前信道质量负相关，也即是，当前信道质量越好，目标重复发送次数越小，这是因为，当前信道质量越好，UE向基站重复越少次数发送该目标上行数据就可以保证基站能够正确接收到该目标上行数据。
由于目标重复发送次数不仅受到目标TBS的影响，还受到当前信道质量的影响，同时，由于在向UE发送目标随机接入响应时，基站无法预知UE所需传输的数据包的大小，也即是基站无法预知UE选择的目标TBS，因此，一方面，UE无法单独根据目标TBS确定目标重复发送次数，另一方面，基站无法通过重复次数指示信息直接指示目标重复发送次数，故而，在本公开的实施例中，UE需要根据重复次数指示信息和目标TBS确定目标重复发送次数，其中，重复次数指示信息可以由基站根据当前信道质量生成。
本公开实施例提供了两种示例性的UE根据重复次数指示信息和目标TBS 确定目标重复发送次数的方式，其中：
第一种方式，UE根据重复次数指示信息，从UE存储的至少一个对应关系集合中确定目标对应关系集合，而后，UE根据目标TBS查询目标对应关系集合，得到与目标TBS对应的重复发送次数，UE将该与目标TBS对应的重复发送次数确定为目标重复发送次数。
在这种方式中，基站可以预先通过高层信令向UE发送至少一个对应关系集合，其中，每个对应关系集合可以包括至少一个对应关系，该对应关系为TBS与重复发送次数的对应关系。
表3示出了基站通过高层信令向UE下发的4个示例性的对应关系集合。
表3
Figure PCTCN2018086385-appb-000003
由表3可知，对应关系集合1包括4个对应关系，该4个对应关系分别为TBS1—rep_11，TBS2—rep_21，TBS3—rep_31和TBS4—rep_41，其中，TBS1—rep_11为TBS1与重复发送次数rep_11的对应关系，其他对应关系与其同理，本公开实施例在此不再赘述。
在实际实现时，基站向UE下发的对应关系集合可以包括第一对应关系和第二对应关系，其中，第一对应关系包括相互对应的第一TBS和第一重复发送次数，第二对应关系包括相互对应的第二TBS和次数指示信息，该次数指示信息用于指示第二重复发送次数与第一重复发送次数的相对关系，其中，该第二重复发送次数为第二TBS对应的重复发送次数。可选的，第二重复发送次数与第一重复发送次数的相对关系指的是：第二重复发送次数与第一重复发送次数的差值。
例如，在上述表2的对应关系集合1包括的4个对应关系中，TBS1—rep_11可以是第一对应关系，TBS2—rep_21，TBS3—rep_31和TBS4—rep_41可以是第二对应关系，其中，第一对应关系中的rep_11是TBS1对应的重复发送次数，该rep_11是一个绝对的数值，而第二对应关系中的rep_21、rep_31和rep_41是次数指示信息，其指示的分别是TBS2对应的重复发送次数相较于rep_11的差值、TBS3对应的重复发送次数相较于rep_11的差值和TBS4对应的重复发送次数相较于rep_11的差值。
在接收到基站通过高层信令发送的至少一个对应关系集合之后，UE可以将该至少一个对应关系集合存储至UE本地。
在接收到UE发送的目标随机接入前导之后，基站可以根据当前信道质量生成重复次数指示信息，并通过目标随机接入响应向UE发送该重复次数指示信息，该重复次数指示信息可以指示该至少一个对应关系集合中的一个对应关系集合(也即是目标对应关系集合)。
UE在接收到目标随机接入响应后，可以从该目标随机接入响应中提取该重复次数指示信息，而后，UE可以根据该重复次数指示信息确定目标对应关系集合，并根据目标TBS查询该目标对应关系集合，得到与目标TBS对应的重复发送次数，UE可以将该重复发送次数确定为目标重复发送次数。
例如，基站通过目标随机接入响应发送的重复次数指示信息所指示的目标对应关系集合为表2所示的对应关系集合1，UE确定的目标TBS为TBS1，则UE可以根据TBS1查询对应关系集合1，得到与TBS1对应的重复发送次数为rep_11，而后，UE可以将该rep_11确定为目标重复发送次数。
第二种方式，重复次数指示信息可以指示第三重复发送次数，其中，第三重复发送次数与第三TBS对应，UE可以根据目标TBS、第三TBS和第三重复发送次数确定目标重复发送次数。
在这种方式中，基站可以根据当前信道质量确定重复发送次数集合，该重复发送次数集合包括通信协议所支持的多个重复发送次数中的至少一个重复 发送次数，该重复发送次数集合还可以包括该至少一个重复发送次数分别对应的TBS，而后，基站可以通过高层信令向UE发送该重复发送次数集合。UE在接收到该重复发送次数集合后，可以将该重复发送次数集合存储至UE本地。
在接收到UE发送的目标随机接入前导后，基站可以从该重复发送次数集合中选择一个重复发送次数(也即是第三重复发送次数)，可选的，基站选择的重复发送次数可以是该重复发送次数集合中最小的重复发送次数，或者，基站选择的重复发送次数可以是该重复发送集合中最大的重复发送次数。
而后，基站可以生成用于指示该选择的重复发送次数(也即是第三重复发送次数)的重复次数指示信息，并通过目标随机接入响应向UE发送该重复次数指示信息。
UE在接收到目标随机接入响应后，可以从该目标随机接入响应中提取该重复次数指示信息，而后，UE可以根据目标TBS、第三TBS和第三重复发送次数确定目标重复发送次数。
本公开实施例提供了两种可能的UE根据目标TBS、第三TBS和第三重复发送次数确定目标重复发送次数的实现方式，其中：
在第一种可能的实现方式中，UE可以根据目标TBS和第三TBS的相对关系，确定第一相对关系，该第一相对关系是目标重复发送次数和第三重复发送次数的相对关系，而后，UE可以根据第一相对关系以及第三重复发送次数确定目标重复发送次数。
可选的，目标TBS和第三TBS的相对关系指的可以是目标TBS和第三TBS的比例关系，该第一相对关系指的可以是目标重复发送次数和第三重复发送次数的比例关系。
在这种实现方式中，UE可以根据第一公式计算目标重复发送次数，其中，第一公式为：
rep_y＝ceil[rep_x*(TBS_y/TBS_x)]；
rep_y是目标重复发送次数，ceil是向上取整运算符，rep_x是第三重复发 送次数，TBS_y是目标TBS，TBS_x是第三TBS。
在第二种可能的实现方式中，UE可以根据目标TBS和第三TBS的相对关系，确定第二相对关系，该第二相对关系是参考重复发送次数和第三重复发送次数的相对关系，而后，UE可以根据第二相对关系和第三重复发送次数确定参考重复发送次数，并根据参考重复发送次数确定目标重复发送次数。
可选的，目标TBS和第三TBS的相对关系指的可以是目标TBS和第三TBS的比例关系，该第二相对关系指的可以是参考重复发送次数和第三重复发送次数的比例关系。
在这种实现方式中，UE可以根据第二公式计算参考重复发送次数，其中，第二公式为：
rep_z＝ceil[rep_x*(TBS_y/TBS_x)]；
rep_z是参考重复发送次数，ceil是向上取整运算符，rep_x是第三重复发送次数，TBS_y是目标TBS，TBS_x是第三TBS。
本公开实施例提供了两种可能的UE根据参考重复发送次数确定目标重复发送次数的实现方式，其中：
在第一种可能的实现方式中，UE根据参考重复发送次数确定目标重复发送次数，其中，该目标重复发送次数是目标数值集合中与参考重复发送次数的差值最小的数值，该目标数值集合包括至少一个数值，该目标数值集合包括的数值为第一预设数值的整数倍，或者，该目标数值集合包括的数值为第二预设数值的整数幂。
可选的，该第一预设数值和该第二预设数值可以相同，也可以不相同，在本公开的一个实施例中，该第一预设数值和该第二预设数值可以均为2。
在第二种可能的实现方式中，UE根据参考重复发送次数确定目标重复发送次数，其中，该目标重复发送次数是通信协议所支持的重复发送次数中与参考重复发送次数的差值最小的重复发送次数。
步骤406、UE基于目标重复发送次数，在随机接入的过程中向基站发送 目标上行数据。
在EDT技术中，UE可以在随机接入过程的信息3(英文：message 3)中向基站发送目标上行数据。
UE可以利用自身基于上行资源指示信息所指示的RU个数以及目标TBS确定的调制编码方式对目标上行数据进行调制编码，而后，UE可以向基站重复发送该经过调制编码的目标上行数据，其中，UE向基站重复发送该经过调制编码的目标上行数据的次数为目标重复发送次数。
步骤407、在随机接入的过程中，基站接收UE基于目标重复发送次数发送的目标上行数据。
由于基站无法预知UE选择的目标TBS，因此，在步骤407中，基站可以利用可用的TBS依次对承载有目标上行数据的上行资源进行检测，直至获取能够正确接收该目标上行数据的TBS，该TBS即为目标TBS。
基站可以根据该目标TBS和重复次数指示信息确定目标重复发送次数，并基于该目标重复发送次数接收UE发送的目标上行数据。
综上所述，本公开实施例提供的数据传输方法，通过接收基站发送的携带于目标随机接入响应中的重复次数指示信息，并基于目标重复发送次数，在随机接入的过程中向基站发送目标上行数据，其中，该目标重复发送次数是根据重复发送次数指示信息和目标传输块大小确定的，使得在EDT技术中，用户设备可以向基站重复发送目标上行数据，从而解决了EDT技术中用户设备如何向基站重复发送上行数据的问题。
