随着信息技术的快速发展，当今的世界已经进入万物互联的时代，各种物联网技术层出不穷。其中，窄带物联网(narrow band internet of things，NB-IOT)作为万物互联网络的一个重要分支，以其高连通性、高穿透力的特性很快在物联网水表、物联网燃气表等领域得到广泛应用。
目前，为了解决深度覆盖问题，在NB-IOT技术中，通常是通过减小信号发射带宽以及增加信号重复发送次数来提高接收端的信噪比，从而提高解码成功率。但是在现有技术中，接收端必须要在接收到发送端发送的所有重复信号后才进行解调译码，而实际应用中由于信号传输环境的复杂及外界噪声干扰的影响，实际空口环境是时变的，可能只需要少量重复甚至一次重复的数据传输即可译码成功，所以，现有的用于窄带物联网的数据传输和解调译码的方法会造成空口资源的浪费以及发送端的功耗浪费。

具体实施方式
本申请实施例提供了一种用于窄带物联网的数据传输方法、装置、存储介质及设备， 在进行窄带物联网中的数据传输时，提前对重复信号进行译码，并在译码成功后提前终止剩余重复信号的收发处理，从而不仅能够降低发送端的功率消耗，而且还可以将剩余的空口信道资源用于发送端与其他接收端的通信，进而提高了空口频谱利用率。
下面结合附图，对本申请的实施例进行描述。
在一些用于窄带物联网的数据传输方法中，通常是接收端要在接收到发送端发送的所有重复信号后才进行解调译码，而实际应用中由于信号传输环境的复杂及外界噪声干扰的影响，实际空口环境是时变的，可能只需要少量重复甚至一次重复的数据传输即可译码成功，所以，现有的用于窄带物联网的数据传输和解调译码的方法会造成空口资源的浪费以及发送端的功耗浪费。
为了解决上述问题，本申请提供了一种用于窄带物联网的数据传输方法，不仅能够降低发送方的功率消耗，还可以提高空口频谱利用率。具体来讲，接收端首先接收发送端发送的下行调度指令，其中，下行调度指令用于指示接收端通过预设的空口信道接收发送端发送的N次重复信号，然后，接收端可以根据接收到的下行调度指令，通过预设的空口信道逐次接收发送端发送的重复信号，接着，在接收了M次重复信号后，判断接收到的M次重复信号是否满足预设译码条件；其中，M为大于0且小于N的正整数，若满足，则对接收到的M次重复信号进行译码，并在译码成功后，向发送端发送ACK响应信息，以及停止接收发送端发送的剩余次数的重复信号。可见，由于本申请实施例提前对重复信号进行了译码，并在译码成功后提前终止剩余重复信号的收发处理，从而不仅能够降低发送端的功率消耗，而且还可以将剩余的空口信道资源用于发送端与其他接收端的通信，进而提高了空口频谱利用率。
参见图1，为本实施例提供的一种用于窄带物联网的数据传输方法的流程示意图，该方法包括以下步骤：
S101：接收发送端发送的空口调度指令，其中，空口调度指令用于指示接收端通过预设的空口信道接收发送端发送的N次重复信号；N为大于0的正整数。
在窄带物联网中，各个通信设备(如基站或终端设备等)之间进行通信时，作为发送端的通信设备往往会多次向作为接收端的通信设备发送重复信号，以提高接收端的信噪比，进而提高解码成功率。为了提高空口信道的频谱利用率，接收端首先可以接收发送端发送的空口调度指令，用以执行后续步骤S102。
其中，空口调度指令指的是用于指示接收端通过预设的空口信道接收发送端发送的N次重复信号的空口指令。N为大于0的正整数。即，发送端和接收端在进行数据通信之前，发送端首先可以向接收端发送空口调度指令，用以告知接收端后续可以在特定的空口信道上接收发送端发送的N次重复信号。
S102：根据空口调度指令，通过预设的空口信道逐次接收发送端发送的重复信号。
在本实施例中，接收端通过步骤S101接收到发送端发送的空口调度指令后，进一步可以根据该空口调度指令，通过其指示的预设的空口信道，逐次接收发送端发送的重复信号，用以执行后续步骤S103。
S103：在接收了M次重复信号后，判断M次重复信号是否满足预设译码条件；其 中，M为大于0且小于N的正整数。
在本实施例中，接收端在通过预设的空口信道逐次接收发送端发送的重复信号的过程中，当接收了M次重复信号后，进一步可以判断M次重复信号是否满足预设译码条件；若满足，则继续执行后续步骤S104，若不满足，则继续接收发送端发送的剩余次数的重复信号。
其中，M指的是预先设定的进行预设译码条件判断的次数阈值，且M为大于0且小于N的正整数，具体取值可根据实际情况进行设置，比如可以将M取值为1或3等。
预设译码条件指的是用于判断是否对以接收到的重复信号进行译码的判断条件。一种可选的实现方式是，预设译码条件指的是M次重复信号对应的合并信号的信噪比达到预设阈值(具体取值可根据实际情况进行设定)。也就是说，接收端在接收了M次重复信号，可以判断这M次重复信号对应的合并信号的信噪比是否达到预设阈值，若是，则表明可以提前对这M次重复信号进行译码，无需等待接收N次重复信号，但若没有达到预设阈值，则需要继续接收发送端发送的第M+1次及后续剩余次数的重复信号，并逐次判断对应的合并信号的信噪比是否达到预设阈值，依次类推，直至满足预设阈值，实现对接收到的重复信号的提前译码，进而可以执行后续步骤S104。
需要说明的是，预设译码条件还可以是其他判断条件，比如，可以是当前接收的重复信号次数是否已接近历史译码成功时接收的重复信号次数，若是，则可以提前进行译码。具体的条件设置情况可根据实际情况进行选择，本申请实施例对此不进行限定。
S104：若是，则对接收到的M次重复信号进行译码，并在译码成功后，向发送端发送确认响应信息ACK，以及停止接收发送端发送的剩余次数的重复信号。
在本实施例中，若接收端在接收了M次重复信号后，判断出M次重复信号满足预设译码条件，则对接收到的这M次重复信号进行译码，并在译码成功后，向发送端发送确认响应信息(acknowledgment，ACK)，以及停止接收发送端发送的剩余次数的重复信号。
其中，确认响应信息ACK指的是用于告知发送端，接收端已经成功对重复信号进行译码的确认消息，以便发送端停止发送后续剩余次数的重复信号，降低发送端的功率消耗。
需要说明的是，为提高ACK的发送效率，一种可选的实现方式是，接收端在进行数据传输之前，可以预先与发送端构建快速反馈信道，并利用该快速反馈信道发送确认响应信息ACK，以便发送端在发送第M+1次重复信号之前，即可接收到该确认消息，从而能够及时停止发送第M+1次重复信号及后续的剩余次数的重复信号。其中，快速反馈信道可以是利用已有协议中的定义(如半静态调度(semi-persistent scheduling，SPS)或新增协议定义进行构建的。这样，不仅能够降低发送端的功率消耗，而且还可以将剩余的空口信道资源用于发送端与其他接收端的通信，进而提高了空口频谱利用率。
综上，本实施例提供的一种用于窄带物联网的数据传输方法，在进行窄带物联网中的数据传输时，接收端首先接收发送端发送的下行调度指令，其中，下行调度指令 用于指示接收端通过预设的空口信道接收发送端发送的N次重复信号；N为大于0的正整数，然后，根据接收到的下行调度指令，通过预设的空口信道逐次接收发送端发送的重复信号，接着，在接收了M次重复信号后，判断接收到的M次重复信号是否满足预设译码条件；其中，M为大于0且小于N的正整数，若是，则对接收到的M次重复信号进行译码，并在译码成功后，向发送端发送ACK响应信息，以及停止接收发送端发送的剩余次数的重复信号。可见，由于本申请实施例提前对重复信号进行了译码，并在译码成功后提前终止剩余重复信号的收发处理，从而不仅能够降低发送端的功率消耗，而且还可以将剩余的空口信道资源用于发送端与其他接收端的通信，进而提高了空口频谱利用率。
接下来，为便于理解，现以基站作为发送端、以终端作为接收端为例，对上述用于窄带物联网的数据传输方法进行介绍，如图2所示，具体实现过程包括下述步骤A1-A7：
步骤A1：基站向终端发送空口调度指令。
其中，基站负责空口资源的分配调度，并通过空口调度指令将资源调度结果告知给终端。以便终端按照基站的指示，在特定的空口资源上接收基站发送的N次重复信号。
步骤A2：基站向终端发送第1次重复信号。
步骤A3：终端在接收到第1次重复信号后，判断是否满足预设译码条件，若满足，则尝试进行译码，并在译码成功后执行A6且不进行后续重复信号的接收，若不满足，或者译码失败，则继续接收后续的重复信号。
步骤A4：基站向终端发送第M次重复信号。
其中，M为小于N的正整数。
步骤A5：终端在接收到第M次重复信号后，判断是否满足预设译码条件，若满足，则尝试进行译码，并在译码成功后执行A6且不进行后续重复信号的接收，若不满足，或者译码失败，则继续接收后续的重复信号。
步骤A6：终端向基站发送确认响应信息ACK。
步骤A7：基站在接收到终端返回的确认响应信息ACK后，停止向终端发送剩余次数的重复信号。
基站在获取到终端发送的译码成功的确认信息ACK后，立即停止剩余重复信号的发送，并可将剩余时间的空口资源分配给其他终端使用。
这样，可以减少基站实际发送信号的重复次数，一方面节省基站功耗，另一方面也可以提高空口频谱资源利用率。
相对应的，为便于理解，接下来，以终端作为发送端、以基站作为接收端为例，对上述用于窄带物联网的数据传输方法进行介绍，如图3所示，具体实现过程包括下述步骤B1-B7：
步骤B1：基站向终端发送空口调度指令。
其中，基站负责空口资源的分配调度，并通过空口调度指令将资源调度结果告知 给终端。以便终端按照基站的指示，在特定的空口资源上向基站发送N次重复信号。
步骤B2：终端向基站发送第1次重复信号。
步骤B3：基站在接收到第1次重复信号后，判断是否满足预设译码条件，若满足，则尝试进行译码，并在译码成功后执行B6且不进行后续重复信号的接收，若不满足，或者译码失败，则继续接收后续的重复信号。
步骤B4：终端向基站发送第M次重复信号。
其中，M为小于N的正整数。
步骤B5：基站在接收到第M次重复信号后，判断是否满足预设译码条件，若满足，则尝试进行译码，并在译码成功后执行B6且不进行后续重复信号的接收，若不满足，或者译码失败，则继续接收后续的重复信号。
步骤B6：基站向终端发送确认响应信息ACK。
步骤B7：终端在接收到基站返回的确认响应信息ACK后，停止向基站发送剩余次数的重复信号。
终端在获取到基站发送的译码成功的确认信息ACK后，立即停止剩余重复信号的发送，从而可以节省终端的功耗。
这样，可以减少终端实际发送信号的重复次数，节省终端的功耗，提高终端电池使用寿命。

在本申请所提供的几个实施例中，应该理解到，所揭露的系统，装置和方法，可以通过其它的方式实现。例如，以上所描述的装置实施例仅仅是示意性的，例如，所述单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另一点，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，装置或单元的间接耦合或通信连接，可以是电性，机械或其它的形式。
所述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部单元来实现本实施例方案的目的。
另外，在本申请各个实施例中的各功能单元可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以两个或两个以上单元集成在一个单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能单元的形式实现。
所述集成的单元如果以软件功能单元的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分或者该技术方案的全部或部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质中，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)执行本申请各个实施例所述方法的全部或部分步骤。而前述的存储介质包括：U盘、移动硬盘、只读存储器(ROM，Read-Only Memory)、随机存取存储器(RAM，Random Access Memory)、磁碟或者光盘等各种可以存储程序代码的介质。
以上所述，以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
