随着通信技术的发展，长期演进(Long Term Evolution，LTE)通信技术已越来越成熟，并且，LTE系统的网络覆盖也越来越密集。
在LTE系统中，密集的网络覆盖使得相邻小区间存在干扰。为降低相邻小区间的干扰，可通过扰码初始化，使发送端设备在每个子帧进行一次扰码初始化，每个子帧内发送的数据均具有不同的扰码，那么发送端设备根据初始化后的扰码对数据块进行加扰，并将加扰后的数据块进行发送，则可实现干扰的随机化。为保证接收端设备可接收到的发送端设备发送的完整数据，该发送端设备可进行数据块的重复发送，并在每个子帧进行一次扰码初始化。

具体实施方式
本申请各实施例提供的数据发送方法，可适用于基于LTE通信技术的网络系统，即LTE网络系统中。LTE网络系统例如可包括物联网(Internet Of Thing，IOT)系统。IOT作为“物物通信的互联网”，可将物品与物品间的信息交换和通信，这样的通信方式也可称为机器间通信(Machine Type Mchine，MTC)。在IOT中的终端也可称为MTC终端。典型的物联网应用包括智能抄表、智能家居等。在IOT中的窄带物联网(Narrow Band Internet of Thing，NB-IOT)中，为保证接收端设备可准确接收完整的数据块，对数据进行重复发送。
需要说明的是，本申请实施例提供的各数据发送方法并不限定用于如上所述的场景，还可用于其他发送端设备与接收端设备间重复传输数据的任一场景中。
本申请实施例提供的各数据发送方法均可由发送端设备执行，该发送端设备可以为终端，也可为网络设备，如基站等。若该发送端设备为终端，该数据发送方法可为用于上行数据传输，若该发送端设备为网络设备，则该数据发送方法还可用于下行数据传输。也就是说，该数据发送方法既可适用于上行数据传输，也可适用于下行数据传输。
图1为本申请实施例一提供的一种数据发送方法的流程图。如图1所示，该方法可包括如下步骤：
S101、进行扰码初始化，产生扰码。
具体地，每进行一次扰码初始化，产生的扰码就会发生变化，实现当前时刻的该扰码与之前时刻的扰码之间的随机化。该S101可以是初次发送该数据块前进行的扰码初始化，也可以是是在其他时刻进行的扰码初始化。
该该S101中可以是采用预设的序列产生器对应的初始化公式进行扰码初始化。该预设的序列产生器例如可以伪随机序列产生器，如Gold序列产生器，也可以为其他类型的序列产生器。
S102、根据该扰码对数据块进行加扰。
该数据块占用至少一个子帧。该S102可以是根据该扰码对该数据块间加扰，可实现数据块中信息的随机化，使得对该加扰后的该数据块的传输过程中便可降低发送端设备所在小区对其他小区的干扰随机化。
S103、重复发送该加扰后的该数据块。
具体地，“重复发送”，顾名思义，发送次数为多次。也就是说，该S103实际是多次发送该加扰后的该数据块，直至距离该数据块的上次加扰初始化的间隔大于或等于该扰码初始化参数阈值。
S104、距离该数据块的上次扰码初始化的间隔大于或等于扰码初始化参数阈值 时，进行扰码初始化，重新产生扰码。
具体地，该扰码初始化参数阈值可以预先配置在发送端设备侧的参数值，也可以为通过信令配置在发送端设备侧的参数值。举例来说，若该发送端设备为终端，则该扰码初始化参数阈值可以为网络设备，如基站，通过高层信令或控制信令所配置的值。
可选的，该间隔可以为时间间隔，该时间间隔可通过时间、子帧数、资源单元(Resource Unit)数等表示。
S105、根据该重新产生的扰码对该数据块再次进行加扰。
具体地，该S105中可以是采用与上述S102中类似的实现方式，对该数据块进行加扰。
S106、重复发送该再次加扰后的该数据块。
本申请实施例一提供的数据发送方法，通过进行扰码初始化产生扰码，根据该扰码对数据块进行加扰，重复发送该加扰后的该数据块，并在距离该数据块的上次扰码初始化的间隔大于或等于扰码初始化参数阈值时，进行扰码初始化重新产生扰码，并根据该重新产生的扰码对该数据块进行加扰，继而重复发送该再次加扰后的该数据块。由于无需在每个子帧内均进行扰码初始化，并且，在距离该数据块的上次扰码初始化的间隔大于或等于扰码初始化参数阈值时进行扰码初始化可保证扰码的随机化，使得本申请实施例的提供的数据发送方法可实现干扰随机化，并且在距离该数据块的上次扰码初始化的间隔小于扰码初始化参数阈值时使用与上次相同的扰码，因而本申请实施例的提供的数据发送方法还可可保证接收端设备可利用重复发送的数据块进行频偏估计等处理，保证发送端设备与接收端设备间传输数据的准确度，提高数据传输效率。
可选的，若该间隔通过子帧数表示。该扰码初始化参数阈值可以为预设的子帧数。
可选的，该间隔对应的子帧数可以包括有效子帧数，也可包括所有子帧数。该发送端设备及接收端设备所在的网络系统可以为基于LTE通信技术的网络系统，如基于LTE通信技术的物联网。有效子帧为基于LTE通信技术的系统中物联网的对应频段资源的子帧。
该数据块占用至少一个子帧，该间隔可通过该数据块在上次扰码初始化后的子帧数表示。数据块的长度可以为数据块占用的子帧数，若该数据块占用至少一个子帧，则该数据块的长度便为至少一个子帧。
举例来说，该数据块可占用一个子帧，也就是说，本申请实施例提供的数据发送方法可应用于数据块占用一个子帧的情况下，在重复发送该数据块的过程中，当距离该数据块的上次扰码初始化的间隔大于或等于扰码初始化参数阈值时，进行扰码初始化。
图2为本申请实施例二提供的一种数据发送方法中数据块占用一个子帧情况下的扰码初始化的示意图。若该扰码初始化参数阈值为Z，也就是说，在本申请实施例的该数据发送方法中，可以是在距离上次扰码初始化的间隔大于或等于Z个子帧数时，进行扰码初始化。
可选的，该方法还可包括：
若该距离该数据块的上次扰码初始化的间隔小于该扰码初始化参数阈值时，在仅 在初次传输该数据块时，对该数据块进行扰码初始化。
可选的，该数据块可以为对待发送数据进行编码及数量匹配后获得的码块。因而，该数据块也可称为速率匹配块(Rate Matched Block，RMB)。
举例来说，该数据块也可占用多个子帧，也就是说，本申请实施例提供的数据发送方法可应用于数据块占用多个子帧的情况下，在重复发送该数据块的过程中，当距离该数据块的上次扰码初始化的间隔大于或等于扰码初始化参数阈值时，进行扰码初始化。
图3为本申请实施例二提供的一种数据发送方法中数据块占用多个子帧情况下的一种扰码初始化的示意图。可选的，该数据块占用多个子帧。
如上所述的S104中距离该数据块的上次扰码初始化的间隔大于或等于扰码初始化参数阈值时，进行扰码初始化，重新产生扰码，可以包括：
若该数据块占用的子帧数大于或等于该扰码初始化参数阈值，每次重复发送该数据块时进行扰码初始化，重新产生扰码。
具体地，若该数据块占用的子帧数，也就是该数据块的长度对应的子帧数大于或等于该扰码初始化参数阈值的情况下，每次重复发送该数据块时，距离该数据块的上次扰码初始化的间隔便会大于或等于扰码初始化参数阈值，因而，可在每次重复发送该数据块时进行扰码初始化。
图4为本申请实施例二提供的一种数据发送方法中数据块占用多个子帧情况下的另一种扰码初始化的示意图。可选的，如上所述的S104中距离该数据块的上次扰码初始化的间隔大于或等于扰码初始化参数阈值时，进行扰码初始化，重新产生扰码，可以包括：
若该数据块占用的子帧数对应的子帧数小于该扰码初始化参数阈值，在距离上次扰码初始化的子帧数大于或等于该扰码初始化阈值时，对该数据块进行扰码初始化。
具体地，若该数据块占用的子帧数对应的子帧数小于该扰码初始化参数阈值，每次重复发送该数据块时，距离该数据块的上次扰码初始化的间隔便会小于扰码初始化参数阈值，因而，本申请实施例的该数据发送方法中无需在每次重复发送该数据块时进行扰码初始化，而是在重复发送多次该数据块直至距离该数据块的上次扰码初始化的间隔大于或等于扰码初始化参数阈值的时，进行扰码初始化。
可选的，该数据块为RMB，或者，RMB的冗余版本(Redundancy Version，RV)对应的码块。RMB为对待发送数据进行编码及速率匹配后的码块。
需要说明是，图3和图4实际是以数据块为RMB情况下进行说明，若该数据块为RMB的RV对应的码块，扰码初始化的示意图与图3和图4类似，在此不再赘述。
可选的，如上所述的S101中进行扰码初始化，产生扰码，以及S104中的进行扰码初始化，重新产生扰码，均可包括：

本申请实施例二的数据发送方法可通过一个子帧的数据块以及多个子帧的数据块的多种数据发送方法进行描述，可使得该数据发送方法在发送一个子帧的数据块和多个子帧的数据块的情况下，均可实现干扰随机化，且还可保证接收端设备可利用重复发送的数据块进行频偏估计等处理，保证发送端设备与接收端设备间传输数据的准确度，提高数据传输效率。

需要说明的是，上述S502具体实现可与上述实施例中S102的实现过程类似，具体可参见上述实施例，在此均不再赘述。
S503、在该每个重复周期内，根据该每个重复周期对应的重复次数，重复发送该加扰后的该数据块。
本申请实施例三提供的数据发送方法，通过在数据块的每个重复周期的开始，进行扰码初始化，产生扰码；该数据块的所有重复周期内的重复次数之和等于该数据块所需的重复次数；根据该扰码对该数据块进行加扰；在该每个重复周期内，根据该每个重复周期对应的重复次数，重复发送该加扰后的该数据块。由于无需在每个子帧内均进行扰码初始化，本申请实施例的提供的数据发送方法可在实现干扰随机化的基础上，还可保证接收端设备可利用重复发送的数据块进行频偏估计等处理，保证发送端 设备与接收端设备间传输数据的准确度，提高数据传输效率。
可选的，该数据块包括多个分块；每个分块对应至少一个子帧。该数据块可占用多个子帧。

具体地，若该数据块包括M个分块，该每个重复周期对应的重复次数例如可以为N。在每个重复周期内，可以先重复发送N次第一个分块、再重复发送N次第二个分块，重复执行，直至重复发送完N次的最后一个分块。
举例来说，该数据块包括多个分块，该数据块具有一个重复周期，且该一个重复周期对应的重复次数等于该数据块所需的重复次数。图6为本申请实施例三提供的一种数据发送方法中扰码初始化的一个示意图。如图6所示，该方法中，发送端设备可以是在该一个重复周期的开始，也就是初次传输该数据块前，进行扰码初始化。
举例来说，若该数据块包括多个分块，该数据块具有多个重复周期，且该多个重复周期对应的重复次数之和等于该数据块所需的重复次数。图7为本申请实施例三提供的一种数据发送方法中的扰码初始化的另一示意图。如图7所示，该方法中，发送端设备可以是在该多个重复周期内的每个重复周期的开始，进行扰码初始化，获得每个重复周期对应的扰码，使得不同重复周期对应的扰码不同，同一重复周期对应一个扰码。
可选的，该数据块为RMB；该RMB为对待发送数据进行编码及速率匹配后的码块；该RMB包括至少两个RV对应的码块。
该每个分块对应一个子帧，或者，一个RV。
具体地，若每个分块对应一个子帧，该数据块具有一个重复周期，则该数据块的发送方式可以为子帧重复(subframe repetition)发送方式。若该数据块具有多个重复周期，则该数据块的发送方式为循环子帧重复(cyclic subframe repetition)发送方式。
若该每个分块对应一个RV，该数据块具有一个重复周期，则该数据块的发送方式为RV重复(RV repetition)发送方式。若该数据块的所有重复周期包括多个重复周期，则该数据块的发送方式为循环RV重复(cyclic RV repetition)发送方式。
需要说明的是，该数据发送方法的S501中进行扰码初始化的具体实现方式可与上述实施例提供的数据发送方法的S101对进行扰码初始化的具体实现方式类似，不再赘述。
本申请实施例三的数据发送方法可通过在该数据块的每个重复周期的开始进行 扰码初始化，可使得该数据发送方法在发送多个子帧的数据块的情况下，不同重复周期内具有不同的扰码，因而可实现干扰随机化，并且在同一重复周期内的扰码相同，因而该方法还可保证接收端设备可利用重复发送的数据块进行频偏估计等处理，保证发送端设备与接收端设备间传输数据的准确度，提高数据传输效率。

采用该发送功率在该子载波间隔为该第一间隔的单个子载波上发送数据块。
具体地，发送端设备可以是采用该发送功率在该子载波间隔为3.75kHz的单载波上进行数据块的传输。也就是说，该发送端设备的传输方式可以为子载波间隔为3.75kHz的单载波传输方式。
可替代地，如上所述的S801中根据子载波间隔，确定带宽参数可包括：
若该子载波间隔为第二间隔，确定该子载波间隔为该第二间隔的子载波的数量为该带宽参数。
具体地，该第二间隔可以为该LTE通信系统对应的子载波间隔。
可选的，如上所述的S803中采用该发送功率在该子载波上发送数据块可以包括：

具体地，发送端设备可以是采用该发送功率在该子载波间隔为15kHz的单载波上进行数据块的传输，也可在该子载波为15kHz的多个子载波上间数据块的传输。
举例来说，该第二间隔可以为15kHz，该第二间隔的子载波的数量为1、3、6或12。也就是说，发送端设备可以是采用该发送功率在该子载波间隔为15kHz的单载波上进行数据块的传输、还可以是采用该发送功率在该子载波间隔为15kHz的3个子载波上进行数据块的传输、也可采用该发送功率在该子载波间隔为15kHz的6个子载波上进行数据块的传输，还可以是采用该发送功率在该子载波间隔为15kHz的12个子载波上进行数据块的传输。

若预设字段的值为第一取值，确定第一小区的操作模式为独立操作模式；
若预设字段的值为第二取值，确定第一小区的操作模式为保护带操作模式。
可选的，如上所述的S1004中根据该窄带主信息块中预设字段的值确定第一小区的操作模式包括：
若预设字段的值为第三取值，确定第一小区的操作模式为带内操作模式，且，第一小区的天线端口数与第二小区的天线端口数相同。
可选的，如上所述的S1004中根据该窄带主信息块中预设字段的值确定第一小区的操作模式包括：
若预设字段的值为第四取值，确定第一小区的操作模式为带内操作模式，且，第一小区的天线端口数与第二小区的天线端口数不同。
具体地，若该预设字段的值为第三取值或第四取值，可确定该发送端设备对应的操作模式为带内操作模式(in-band operation)。也就是说，该第一小区所在网络的频谱资源为第二小区的带内资源中的部分频谱资源。举例来说，窄带物联网使用LTE频谱中的一个或多个180kHz的物理资源块(Physical Resource Block，PRB)进行组网。
窄带物联网的终端在入网的过程中，需要读取窄带物联网广播信道(Narrow Band-Physical Broadcast Channel，NB-PBCH)中周期性广播的窄带主信息块，以获取系统的关键参数。操作模式就是其中一个参数。由于不同操作模式下的关键参数不完全一样，比较好的做法是根据操作模式参数的取值来确定如何解读NB-MIB中除操作模式外所有其他参数。
如果窄带物联网处于带内操作模式，则其所使用的PRB上有一部分符号资源是被LTE小区所占用的，窄带物联网中UE不能使用。在这种情况下，窄带物联网UE还需要从NB-MIB中读取相应LTE小区的参考信号的天线端口数，用于确定已被LTE小区的小区参考信号所占用的资源。
窄带物联网本身的的窄带小区的窄带参考信号对应的天线端口数，可以为1或者2，可由终端在窄带物联网广播信道中的NB-MIB所获得的。LTE小区的小区参考信号对应的天线端口数与窄带小区的窄带参考信号对应的天线端口数的对应关系可如下表2所示。
表2
Figure PCTCN2017076665-appb-000039
根据该表2可知，在已知窄带小区的窄带参考信号对应的天线端口数的情况下，窄带物联网的终端可根据该窄带小区的窄带参考信号对应的天线端口数和LTE小区 的小区参考信号对应的天线端口数是否一样，即可以知道LTE小区的小区参考信号对应的天线端口数。这个信息可以用1个比特来表示。但是由于这个信息只在窄带物联网处于带内操作模式的情况下才有必要存在，所以更高效的编码方式是把这个信息和窄带物联网操作模式联合编码，比如，操作模式的2个比特中，00表示独立操作模式，01表示保护带操作模式，10表示带内操作模式而且窄带小区的窄带参考信号和LTE小区的小区参考信号对应的天线端口数相同，11表示带内操作模式而且窄带小区的窄带参考信号和LTE小区的小区参考信号对应的天线端口数不同。
本申请实施例六提供的数据传输方法，可根据窄带主信息块NB-MIB中预设字段的值确定第一小区操作模式；NB-MIB为第一小区中网络设备所发送的。
