Description

数据传输方法、装置、终端及基站
本公开要求在2018年01月12日提交中国专利局、申请号为201810031211.X的中国专利申请的优先权，该申请的全部内容通过引用结合在本公开中。
技术领域
本公开涉及通信技术领域，例如涉及一种数据传输方法、装置、终端及基站。
背景技术
用户设备(User Equipment，UE)接入无线网络大致过程描述如下：UE在基站配置的接入资源池上随机选择一个接入资源发送接入消息(消息1)；基站在接入资源池上检测接入消息，为每个检测到的接入消息发送反馈消息(消息2)，其中消息2包括上行定时调整信息和UE发送数据包(消息3)时占用的资源的信息；UE在基站分配的资源上向基站发送消息3；当基站成功解码消息3时，基站向终端发送响应消息(消息4)。在该过程中，由于接入资源池是所有UE的共享资源，当UE数量较大时，就可能出现两个或两个以上UE选择相同接入资源，并在相同接入资源上发送消息1的情况(假设有两个UE在相同的接入资源上发送消息1，分别是UE A和UE B)，而基站在相同接入资源上无法识别出多个UE，因此基站会对UE A和UE B发送相同的消息2，这就导致UE A和UE B会在相同的资源上按照相同的传输方式并利用相同的参考信息(如参考信号序列或扰码序列等)发送消息3，从而导致UE A的消息3和UE B的消息3之间相互干扰非常严重，基站无法正确解码UE A和UE B的消息3，一旦基站无法解码消息3，基站又会向UE A和UE B发送相同的用于消息3重传的调度信息，UE A和UE B接收到相同的调度信息后，又会以相同传输方式并利用相同的参考信息重传消息3，从而导致基站无法正确解码消息3，如此循环，达到最大重传次数或重传时间后，UE退出接入过程并重新开始接入。
由此可见，多个UE接入消息的碰撞势必会引发无效的资源调度，从而不仅浪费了大量的无线资源，也增加了UE接入网络所耗费的时间。相关技术中，一种直观的解决方式就是增加接入资源的数量，从而降低用户设备接入冲突的概 率。
但是，由于接入资源的数量需要基站通过系统消息来配置，因此一旦通过系统消息配置了大量的接入资源，当同一时刻用户设备接入的数量不多时，接入资源的数量也不能动态地进行调整，从而造成所配置的接入资源不能得到充分利用，另一方面，由于接入资源是在网络资源中划分的，划分给接入资源的网络资源的数量多了，可用的网络资源数量就会相应缩小，从而降低网络数据传输速率。
发明内容
本公开提供了一种数据传输方法、装置、终端及基站，能够提高正确解码多个UE在相同资源上发送的数据包的概率。
本公开提供了一种数据传输方法，包括：
终端从预设参考信息类型对应的参考信息集合中选择参考信息；

具体实施方式
下文中将结合附图对本公开的实施例进行说明。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。
实施例一
本实施例提供一种数据传输方法，如图1所示，该方法包括如下步骤。
步骤1010、终端从预设参考信息类型对应的参考信息集合中选择参考信息。
在一实施例中，预设参考信息类型包括：参考信号序列、扰码序列、传输资源集合、传输块大小、相位旋转值、传输数据包的基准功率值、传输数据包的抬升功率值7种参考信息类型中的至少一种；其中，第k种参考信息类型包括X k个参考信息，X k为正整数，k＝1、2、…、7。不同参考信息类型包括的参考信息数量可以相同，也可以不同。
在一实施例中，假设预设参考信息类型包括参考信号序列的参考信息类型，那么参考信息集合就是参考信号序列集合，从预设参考信息类型对应的参考信息集合中选择参考信息指的是：从参考信号序列集合中选择参考信号序列；假设预设参考信息类型包括扰码序列的参考信息类型，那么参考信息集合就是扰码序列集合，从预设参考信息类型对应的参考信息集合中选择参考信息指的是：从扰码序列集合中选择扰码序列；假设预设参考信息类型包括参考信号序列的参考信息类型和扰码序列的参考信息类型，那么参考信息集合就是参考信号序 列集合和扰码序列集合，从预设参考信息类型对应的参考信息集合中选择参考信息指的是：从参考信号序列集合中选择参考信号序列，并从扰码序列集合中选择扰码序列。
在一实施例中，当预设参考信息类型包括两种及两种以上参考信息类型时，不同参考信息类型的参考信息之间存在映射关系。举例来说，假设预设参考信息类型包括参考信号序列的参考信息类型和扰码序列的参考信息类型，那么参考信号序列集合中的参考信号序列信息和扰码序列集合中的扰码序列信息之间存在映射关系。
步骤1020、根据选择的参考信息和待发送数据包得到第一目标数据包。
在一实施例中，如果选择的参考信息为参考信号序列，那么第一目标数据包就是加入了参考信号序列的待发送数据包；如果选择的参考信息为扰码序列，那么第一目标数据包就是经过扰码序列加扰的待发送数据包；如果选择的参考信息为参考信号序列和扰码序列，那么第一目标数据包就是经过扰码序列加扰，且加入了参考信号序列的待发送数据包。
步骤1030、向基站发送第一目标数据包。
本实施例提供的数据传输方法，终端从预设参考信息类型对应的参考信息集合中选择参考信息；根据选择的参考信息和待发送数据包得到第一目标数据包；向基站发送第一目标数据包。从本实施例可见，由于参考信息是终端在预设参考信息类型对应的参考信息集合中选择的，不同终端之间选择相同参考信息的概率较低，而当不同终端之间选择的参考信息不同时，数据包之间的干扰会大幅度地降低，从而提高了数据包被正确解码的概率。
在一实施例中，在终端从预设参考信息类型对应的参考信息集合中选择参考信息之前，还包括：终端接收基站发送的包含第一资源标识的调度信息；其中，调度信息用于指示终端发送待发送数据包，第一资源标识用于标识终端发送第一目标数据包时占用的资源。该调度信息通常为物理层对应的调度信息，可以动态调度终端数据传输。
在一实施例中，待发送数据包为终端接入网络过程中消息3对应的数据包，调度信息为终端接入网络过程中消息3对应的调度信息。
在一实施例中，待发送数据包为首次向基站发送的数据包，或者，待发送数据包为向基站重新发送的数据包。所述重新发送的数据包包括：在一次接入过程消息1、消息2、消息3中消息3的重新传输，也包括UE在初次接入网络失败后，再次接入网络尝试过程中消息3的首次传输和重新发送。
在一实施例中，在首次发送待发送数据包时采用相关技术中的技术方案，而在重新发送待发送数据包时，再在预设参考信息类型对应的参考信息集合中选择参考信息，进而重新发送待发送数据包，能够减少基站不必要的盲检复杂度。
在一实施例中，终端从预设参考信息类型对应的参考信息集合中选择参考信息，包括：终端从预设参考信息类型对应的参考信息集合中以预设选择方式选择参考信息。
在一实施例中，预设选择方式包括：随机选择方式，或者，根据终端对应的终端标识进行选择的方式，或者，根据终端的下行测量值进行选择的方式，或者，根据待传输数据包大小进行选择的方式。
在一实施例中，根据终端对应的终端标识进行选择的方式包括：根据终端标识与参考信息建立的映射关系进行选择的方式；举例来说，参考信息包括参考信号序列、扰码序列、传输资源集合、传输块大小、相位旋转值、传输数据包的基准功率值、传输数据包的抬升功率值中的一种或多种，假设参考消息集合为Y种，不同集合之间参考信息不同，如：参考消息集合R0，对应扰码序列为B1，参考信号序列为C1，参考消息集合R1，对应扰码序列B2，参考信号序列为C2，参考消息集合R2，对应扰码序列为B3，参考信号序列为C3，当终端标识为Z时，该终端对应参考消息集合为Zmod Y(mod为取模运算)，终端在接入网络过程中，基站发送消息2指示终端传输消息3的资源位置，终端根据自己的标识，确定对应的参考信息，根据参考信息进行数据包传输。
根据终端的下行测量值进行选择的方式包括：根据终端的下行状态测量值与参考信息建立的映射关系进行选择的方式，或，根据下行路损测量值与参考信息建立的映射关系进行选择的方式，或，根据下行参考信号接收功率测量值与参考信息建立的映射关系进行选择的方式。举例来说，参考信息包括参考信号序列、扰码序列、传输资源集合、传输块大小、相位旋转值、传输数据包的 基准功率值、传输数据包的抬升功率值中一种或多种，不同下行测量值对应不同的参考信息集合，如：下行测量值小于或等于S1，对应扰码序列为B1，参考信号序列为C1，传输数据包的基准功率值为D1，传输数据包的抬升功率值为E1，下行测量值大于S1且小于或等于S2，对应扰码序列B2，参考信号序列为C2，传输数据包的基准功率值为D2，传输数据包的抬升功率值为E2，下行测量值大于S2，对应扰码序列为B3，参考信号序列为C3，传输数据包的基准功率值为D3，传输数据包的抬升功率值为E3，终端在接入网络过程中，基站发送消息2指示终端传输消息3的资源位置，终端进行下行测量，获得下行测量值，根据获得的测量值确定对应的参考信息，根据参考信息进行数据包传输。
根据待传输数据包大小进行选择的方式包括：根据待传输数据包大小与参考信息建立的映射关系进行选择的方式。举例来说，参考信息包括参考信号序列、扰码序列、传输资源集合、传输块大小、相位旋转值、传输数据包的基准功率值、传输数据包的抬升功率值中一种或多种，不同待传输数据包大小对应不同的参考信息集合，如：数据包大小为A1，对应扰码序列B1，参考信号序列为C1，传输数据包的基准功率值为D1，数据包大小为A2，对应扰码序列B2，参考信号序列为C2，传输数据包的基准功率值为D2，数据包大小为A3，对应扰码序列B3，参考信号序列为C3，传输数据包的基准功率值为D3。终端在接入网络过程中，基站发送消息2指示终端传输消息3的资源位置以及可以传输消息3的最大数据包大小，终端根据预先定义的可以传输数据包的大小，在没有超过基站制定的最大数据包大小前提下，选择与当前需要传输的数据包大小最接近的预先定义的数据包进行传输，并且，根据选择传输的数据包大小确定对应的参考信息，根据参考信息进行数据包传输。在一实施例中，所述数据包大小选择包括，基站在系统消息中广播消息可以传输的数据包大小集合，如：A1、A2、A3，假设，A1、A2、A3从小到大排列，基站在消息2中指示消息3可以传输的最大数据包大小为A2，则，终端可以根据自己当前需要传输的数据包在A1和A2之间进行选择，再根据上述数据包大小与参考信息对应关系，选择相应的参考信息，再根据选择的参考信息传输相应的数据包。
在一实施例中，在向基站发送第一目标数据包之后，还包括：接收基站发送的包含第二资源标识的第一重传调度信息；根据第二资源标识重新发送待发送数据包。其中，第一重传调度信息用于指示终端重新发送待发送数据包，第 二资源标识用于标识终端重新发送待发送数据包时占用的资源。
本实施例中，该方案针对的是基站只判断第一目标数据包是否能够解码成功，且经过判断确定第一目标数据包无法成功解码的情况。
在一实施例中，根据第二资源标识重新发送待发送数据包，包括：从预设参考信息类型对应的参考信息集合中以预设选择方式重新选择参考信息；根据重新选择的参考信息和待发送数据包得到第二目标数据包；在第二资源标识对应的资源上向基站发送第二目标数据包。
在一实施例中，向基站发送第一目标数据包之后，还包括：接收基站发送的包含参考信息对应的目标标识信息和第三资源标识的第二重传调度信息；如果第二重传调度信息中目标标识信息与自身发送第一目标数据包时选择的参考信息对应的标识信息相同，根据第三资源标识重新发送待发送数据包。其中，第二重传调度信息用于指示终端重新发送待发送数据包，第三资源标识用于标识终端重新发送待发送数据包时占用的资源。
本实施例中，终端如果经过判断且确定第二重传调度信息中目标标识信息与自身发送第一目标数据包时选择的参考信息对应的标识信息不相同，那说明该重传调度信息不是发给自己的，终端丢弃该重传调度信息。第三资源标识是与目标标识信息相关的标识，举例来说，假设UE A选择一条参考信号序列1与待发送数据包1一起发送，UE B选择另一条参考信号序列2与待发送数据包2一起发送，那么参考信号序列1对应的标识信息和参考信号序列2对应的标识信息必然不同，那么基站就会为UE A和UE B分配不同的资源标识以使得UEA和UE B在不同的资源上重新发送待发送数据包。
在一实施例中，根据第三资源标识重新发送待发送数据包的过程与根据第二资源标识重新发送待发送数据包的过程类似，在此不再赘述。
在一实施例中，该方案针对的是基站判断第一目标数据包是否能够解码成功、是否能够检测到目标标识信息，且经过判断确定第一目标数据包未成功解码但能够检测到目标标识信息的情况。
本实施例提供的数据传输方法，接收基站发送的包含参考信息对应的目标标识信息和第三资源标识的第二重传调度信息；如果第二重传调度信息中目标标识信息与自身发送第一目标数据包时选择的参考信息对应的标识信息相同， 根据第三资源标识重新发送待发送数据包。其中，第二重传调度信息用于指示终端重新发送待发送数据包，第三资源标识用于标识终端重新发送待发送数据包时占用的资源。从本实施例可见，由于第二重传调度信息中包含终端用于判断重传调度信息是否是发给自己的目标标识信息，因此避免了待发送数据包的盲目重传，节省了资源。
在一实施例中，向基站发送第一目标数据包之后，还包括：接收基站发送的包含预设信息和第四资源标识的第三重传调度信息；根据第四资源标识重新发送待发送数据包。其中，包含预设信息的第三重传调度信息用于指示接收到该重传调度信息的终端重新发送待发送数据包，第四资源标识用于标识终端重新发送待发送数据包时占用的资源。
本实施例中，终端接收到包含预设信息的重传调度信息，那无需进行任何判断，直接重新发送待发送数据包。
本实施例中，根据第四资源标识重新发送待发送数据包的过程与根据第二资源标识重新发送待发送数据包的过程类似，在此不再赘述。
本实施例中，该方案针对的是基站判断第一目标数据包是否能够解码成功、是否能够检测到目标标识信息，且经过判断确定第一目标数据包未成功解码且未检测到目标标识信息的情况。
本实施例提供的数据传输方法，接收基站发送的包含预设信息和第四资源标识的第三重传调度信息；根据第四资源标识重新发送待发送数据包。其中，包含预设信息的第三重传调度信息用于指示接收到该重传调度信息的终端重新发送待发送数据包，第四资源标识用于标识终端重新发送待发送数据包时占用的资源。从本实施例可见，由于包含预设信息的第三重传调度信息用于指示接收到该重传调度信息的终端重新发送待发送数据包，因此使得终端在基站既未成功解码第一目标数据包，又无法检测到目标标识信息的情况下能够重新向基站发送待发送数据包，从而保证接入过程的持续进行。
实施例二
本实施例提供另一种数据传输方法，如图2所示，该方法包括如下步骤。
步骤2010、基站接收终端发送的第一目标数据包；其中，第一目标数据包 为终端根据参考信息和待发送数据包得到的，参考信息为终端从预设参考信息类型对应的参考信息集合中选择的。
本实施例提供的数据传输方法，基站接收终端发送的第一目标数据包；其中，第一目标数据包为终端根据参考信息和待发送数据包得到的，参考信息为终端从预设参考信息类型对应的参考信息集合中选择的。从本实施例可见，由于参考信息是终端在与预设参考信息类型对应的参考信息集合中选择的，不同终端之间选择相同参考信息的概率较低，而当不同终端之间选择的参考信息不同时，数据包之间的干扰会大幅度地降低，从而提高了数据包被正确解码的概率。
在一实施例中，在基站接收终端发送的第一目标数据包之前，还包括：向终端发送包含第一资源标识的调度信息；其中，调度信息用于指示终端发送待发送数据包，第一资源标识用于标识终端发送第一目标数据包时占用的资源。
在一实施例中，待发送数据包为终端接入网络过程中消息3对应的数据包，调度信息为终端接入网络过程中消息3对应的调度信息。
在一实施例中，基站接收终端发送的第一目标数据包之后，还包括：判断是否能够成功解码第一目标数据包；如果未成功解码第一目标数据包，为终端分配第二资源标识；向终端发送包含第二资源标识的第一重传调度信息。其中，第二资源标识用于标识终端重新发送待发送数据包时占用的资源，第一重传调度信息用于指示终端重新发送待发送数据包。
在一实施例中，在基站接收终端发送的第一目标数据包之后，还包括：判断是否能够成功解码第一目标数据包，且是否能够检测到与参考信息对应的目标标识信息；如果未成功解码第一目标数据包且检测到目标标识信息，为终端分配第三资源标识；向终端发送包含目标标识信息和第三资源标识的第二重传调度信息。其中，第三资源标识用于标识终端重新发送待发送数据包时占用的资源，第二重传调度信息用于指示终端重新发送待发送数据包。
本实施例提供的数据传输方法，判断是否能够成功解码第一目标数据包，且是否能够检测到与参考信息对应的目标标识信息；如果未成功解码第一目标数据包且检测到目标标识信息，为终端分配第三资源标识；向终端发送包含目标标识信息和第三资源标识的第二重传调度信息。其中，第三资源标识用于标 识终端重新发送待发送数据包时占用的资源，第二重传调度信息用于指示终端重新发送待发送数据包。从本实施例可见，由于第二重传调度信息中包含终端用于判断重传调度信息是否是发给自己的目标标识信息，因此避免了待发送数据包的盲目重传，节省了资源。
在一实施例中，上述方法还包括：如果未成功解码第一目标数据包且未检测到目标标识信息，为终端分配第四资源标识；向终端发送包含预设信息和第四资源标识的第三重传调度信息；其中，包含预设信息的第三重传调度信息用于指示接收到该重传调度信息的终端重新发送待发送数据包。其中，第四资源标识用于标识终端重新发送待发送数据包时占用的资源。
本实施例提供的数据传输方法，如果未成功解码第一目标数据包且未检测到目标标识信息，为终端分配第四资源标识；向终端发送包含预设信息和第四资源标识的第三重传调度信息；其中，包含预设信息的第三重传调度信息用于指示接收到该重传调度信息的终端重新发送待发送数据包。其中，第四资源标识用于标识终端重新发送待发送数据包时占用的资源。从本实施例可见，由于包含预设信息的第三重传调度信息用于指示接收到该重传调度信息的终端重新发送待发送数据包，因此使得终端在基站既未成功解码第一目标数据包，又无法检测到目标标识信息的情况下能够重新向基站发送待发送数据包，从而保证接入过程的持续进行。
下面通过一系列具体实施例来说明本公开提供的数据传输方法，在具体实施例的说明之前，首先对具体实施例涉及的技术术语进行简单地说明。
参考信号序列包括：参考信号序列循环移位间隔，或者时域正交码序列，或者参考信号序列循环移位间隔和时域正交码序列，或者参考信号序列循环移位间隔和根序列。
本实施例中，参考信号序列循环移位间隔包括：N/4、N/3、N/6、N/12，N为参考信号序列长度。
时域正交码序列包括：当一次传输时域上包括两个时域正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号时(如：长期演进(Long Term Evolution，LTE)系统中一个子帧包括两个时域OFDM符号参考信号，可以参考LTE系统上行参考信号序列时域正交码应用)，时域正交码序 列包括{1,1}，{1,-1}，当一次传输时域上包括四个时域OFDM符号时(如：一个子帧包括四个时域OFDM符号参考信号，或者，两个子帧包括四个时域参考信号OFDM符号上，相当于将1条参考信号序列通过时域扩频扩展到4个时域参考信号OFDM符号上)，时域正交码序列包括{1,1,1,1}，{1,-1,1,-1}，{1,1,-1,-1}，{1,-1,-1,1}。
根序列包括根序列组信息，根序列组信息的产生可以参考LTE标准。
当循环移位间隔包括N/12时，参考信号序列包括12个序列；当循环移位间隔包括N/6时，参考信号序列包括6个序列；当循环移位间隔包括N/4时，参考信号序列包括4个序列；当循环移位间隔包括N/3时，参考信号序列包括3个序列；当时域正交码序列信息包括{1,1}和{1,-1}，循环移位间隔包括N/3时，参考信号序列包括6个序列(时域正交码和循环移位叠加使用)；当时域正交码序列信息包括{1,1}和{1,-1}，循环移位间隔包括N/6时，参考信号序列包括12个序列(时域正交码和循环移位叠加使用)。
多个资源集合包括：通过非正交传输方式使得一个资源集合由复用一个UE变为可以复用多个UE；即：由一个资源集合变为R个资源集合，R为预定义和配置的。其中，非正交传输方式包括：稀疏码分多址接入(Sparse Code Multiple Access，SCMA)、多用户共享接入(Multi-User Shared Access，MUSA)、非正交编码多重存取(Non-Orthogonal Coded Multiple Access，NCMA)、非正交多址接入(Non-Orthogonal Multiple Access，NOMA)、模式划分多路存取(Pattern Division Multiple Access，PDMA)、资源扩展多址(Resource Spread Multiple Access，RSMA)、交错网格多址(Interleave-Grid Multiple Access，IGMA)、具有特征向量扩展的低密度扩频(Low Density Spreading with Signature Vector Extension，LDS-SVE)、低码率和基于签名的共享访问(Low Code Rate and Signature based Shared Access，LSSA)、非正交编码存取(Non-Orthogonal Coded Access，NOCA)、交织多址接入(Interleave Division Multiple Access，IDMA)、重复分割多路存取(Repetition Division Multiple Access，RDMA)、分组正交编码存取(Group Orthogonal Coded Access，GOCA)。
实施例三
在本实施例中，目标传输方式为在数据包中加入参考信号序列的传输方式， 基站在系统消息中携带传输方式信息，该信息表示UE是否使用从多个参考信号序列中选择一个参考信号序列和数据包一起发送；当使用时，基站在系统消息中还携带多个参考信号序列的信息。
在增强的机通信型(enhanced Machine Type of Communication，eMTC)系统中数据包对应的参考信号序列的循环移位量为固定值，这使得在相同资源发送接入消息的UE A和UE B，会在相同资源上发送相同的参考信号序列，这就导致UE A和UE B的数据包相互干扰，基站很难解码正确，然而，使用了本公开提供的方案可以使得缓解该问题，应用如下。
在eMTC系统中，基站在系统消息、或在反馈消息、或在重传调度信息中携带传输方式的信息，传输方式的信息可以用1个比特进行表示，其中0表示采用相关技术中的技术方案，1表示UE从多个参考信号序列中选择一个参考信号序列和数据包一起传输。
假设，基站配置该信息为1，并配置参考信号序列集合包括8个序列(序列编号为0到7)，序列集合根据循环移位间隔为N/4(N为基础序列长度)和时域正交码{1,1}，{1，-1}，在基础序列变换后获得，基础序列根据基站分配的频域带宽和eMTC R13(TS36.211 d10)标准相关内容确定。
UE A和UE B在基站配置的接入资源池上选择了相同的接入资源发送接入消息(物理随机接入信道(Physical Random Access Channel，PRACH))，基站在接入资源池上检测到接入消息，基站针对接入消息发送反馈消息，反馈消息包括上行定时调整信息和UE发送数据包时占用的资源的信息，UE A和UE B在相同的资源(基站分配的资源)上发送数据包给基站。
当UE A和UE B获知基站使能了新的传输方式(从多个参考信号序列中选择一个参考信号序列和数据包一起传输方式)时，UE A和UE B分别从8条序列集合中随机选择1条参考信号序列和数据包一起发送，假设UE A选择参考信号序列1，UE B选择参考信号序列3。
基站在分配的资源上分别按照序列集合中每个序列检测解码数据包，当基站没有解码成功数据包时，基站发送用于指示终端重新发送数据包的重传调度信息。
UE A和UE B都会检测到基站发送的重传调度信息，UE A和UE B继续从 参考信号序列集合中随机选择一个参考信号与数据包进行传输。
基站继续按照序列集合中每个序列检测解码数据包，当基站没有解码成功数据包时，基站继续发送重传调度信息；如果解码成功，基站发送数据包的响应消息给终端。
需要说明的是，由于UE A和UE B每次发送数据包时都会随机选择参考信号序列传输，这就使得必然会有一次或多次UE A和UE B会选择不同的参考信号序列，从而避免了UE A和UE B持续在相同资源上采用相同的参考信号序列发送数据包的问题，提高了基站解码数据包的成功概率。
实施例四
在本实施例中，目标传输方式为在数据包中加入参考信号序列和扰码序列的传输方式，基站在系统消息中携带传输方式信息，该信息表示UE是否使用从多个参考信号序列中选择一个参考信号序列和数据包一起发送，并在多个扰码序列中选择一个序列来加扰数据包。
当使用时，基站在系统消息中还携带多个参考信号序列信息，参考信号序列可以根据基站配置的循环间隔以及是否支持时域正交码来确定，也可以预先定义，不通过信令配置，如：多个参考信号序列固定为8条，根据时域正交码序列信息{1,1}和{1,-1}，循环移位间隔N/4产生，或者，多个参考信号序列固定为6条，根据循环移位间隔N/6产生，或者，多个参考信号序列固定为4条，根据时域正交码序列{1,1,1,1}，{1,-1,1,-1}，{1,1,-1,-1}，{1,-1,-1,1}产生。
扰码序列可以按照LTE系统中扰码序列产生方式产生，LTE系统扰码初始参数计算方式如下，按照下述方式每个UE发送数据包时可以产生1条扰码序列；
Figure PCTCN2019071278-appb-000001
其中，n RNTI为无线网络临时标识，q＝0或1，n s为时隙索引，
Figure PCTCN2019071278-appb-000002
为小区标识。
基于上述公式引入参数k和n，k为多个扰码序列的索引，n为最大扰码序列索引对应的比特数，如：扰码序列为4条，n为2，k取值为0,1,2,3；扰码序列为8条，n为3，k取值为0,1,2,3,4,5,6,7；扰码序列为6条，n为3，k取值为0,1,2,3,4,5。
在一实施例中，扰码初始参数可以参考下述形式：
Figure PCTCN2019071278-appb-000003
或下述形式：
Figure PCTCN2019071278-appb-000004
在LTE系统中在相同资源发送接入消息的UE A和UE B，会在相同的资源上发送相同的参考信号序列，这就导致UE A和UE B的数据包相互干扰，基站很难解码正确，然而，使用了本公开提供的数据传输方法可以缓解该问题，应用如下。
基站在系统消息、或在反馈消息、或在重传调度信息中携带传输方式信息，传输方式的信息可以用1个比特进行表示，其中0表示采用相关技术中的技术方案，1表示UE从多个参考信号序列和多扰码序列中选择一个参考信号序列和一个扰码序列，同数据包一起发送。
假设，基站配置该信息为1，并配置参考信号序列集合包括6个序列(序列编号为0到5)，序列集合根据循环移位间隔为N/6(N为基础序列长度)，在基础序列变换后获得，基础序列根据基站分配的频域带宽和eMTC R13(TS36.211d10)标准第5.5节相关内容确定。
UE A和UE B在基站配置的接入资源池上选择了相同的接入资源发送接入消息(PRACH)，基站在接入资源池上检测到接入消息，基站针对接入消息发送反馈消息，反馈消息包括上行定时调整信息和UE发送数据包时占用的资源的信息(参考TS36.213标准)，UE A和UE B在相同的资源(基站分配的资源)发送数据包给基站。
当UE A和UE B获知基站使能了新的传输方式(从多个参考信号序列中选择一个参考信号序列，并从多个扰码序列中选择一个扰码序列和数据包一起传输方式)时，UE A和UE B分别从6条参考信号序列集合和6条扰码序列集合中随机选择1条参考信号序列和1条扰码序列，和数据包一起传输；其中，参考信号序列和扰码序列一一对应，如：参考信号序列索引k对应扰码序列索引k。假设，UE A选择参考信号序列1和扰码序列1，UE B选择参考信号序列3和扰码序列3。
基站在分配的资源上分别按照序列集合中每个序列和扰码序列集合中相应扰码序列解码数据包，当基站没有解码成功数据包，检测到参考信号序列1和参考信号序列3时，基站可以判断有两个UE在相同资源上发送数据包，基站发送用于指示终端重新发送数据包的重传调度信息，并在重传调度信息中携带对应目标传输方式的目标传输标识，在本实施例中，目标传输标识为参考信号序列索引信息(该信息为基站检测到参考信号序列的信息)。
UE A和UE B都会检测到基站发送的重传调度信息，当UE A检测到重传调度信息中携带的参考信号序列索引信息与自己上次传输选择的参考序列信息(参考信号序列1)一致时，认为该重传调度信息是发给自己，UE A按照该重传调度信息重新发送数据包，当UE A发现重传调度信息中携带的参考信号序列索引信息与自己上次传输选择的参考序列信息(参考信号序列1)不一致时，认为该重传调度信息不是发给自己，继续进行下行控制信息监测。UE B对于重传调度信息的处理过程与UE A相同。
这样，UE A和UE B根据基站调度，可以在不同的资源上发送数据包，避免了UE A和UE B持续在相同资源上发送数据包，提升解码数据包的成功率。
基站在分配的资源上分别按照序列集合中每个序列检测解码数据包，当基站没有解码成功数据包，也没检测到参考信号序列时，基站发送重传调度信息，并在重传调度信息中携带参考序列信息设定为特定值，该特定值表示对任何UE都有效，这样，UE A和UE B都检测到该重传调度信息，UE A和UE B都按照重传调度信息重新随机选择参考信号序列和扰码序列，并在重传调度信息指示的资源上重新发送数据包。
如果仍然无法解码数据包，重复上述过程。
如果参考信号序列数量和扰码序列数量不等，基站需要按照多种可能进行检测；如：扰码序列数量大于参考信号序列数量，则，一个参考信号序列会对应多个扰码序列，基站需要针对一个参考信号序列对应多个扰码序列进行检测解码。
实施例五
在本实施例中，目标传输方式为在数据包中加入参考信号序列、扰码序列和资源集合的传输方式，基站在系统消息中携带传输方式信息，该信息表示UE 是否使用从多个参考信号序列和多扰码序列、多个资源集合中选择一个参考信号序列同数据包一起发送，并在多个扰码序列集合中选择一个扰码序列来加扰数据包，在多个资源集合中选择一个资源集合来发送数据包。
在基于蜂窝的窄带物联网(Narrow Band Internet of Things,NB-IoT)系统中在相同资源发送接入消息的UE A和UE B，会在相同的资源上发送相同的参考信号序列，这就导致UE A和UE B的数据包相互干扰，基站很难解码正确，然而，使用了本公开提供的数据传输方法可以缓解该问题，应用如下。
基站在系统消息、或在反馈消息、或在重传调度信息中携带传输方式信息，传输方式的信息可以用1个比特进行表示，其中0表示采用相关技术中的技术方案，1表示UE从多个参考信号序列中选择一个参考信号序列同数据包一起发送，并在多个扰码序列集合中选择一个扰码序列来加扰数据包，在多个资源集合中选择一个资源集合来发送数据包；或者，0表示采用相关技术中的技术方案，1表示在接入失败时使用从多个参考信号序列中选择一个参考信号序列同数据包一起发送，并在多个扰码序列集合中选择一个扰码序列来加扰数据包，在多个资源集合中选择一个资源集合来发送数据包；或者，0表示采用相关技术中的技术方案，1表示在重新发送数据包时从多个参考信号序列中选择一个参考信号序列同数据包一起发送，并在多个扰码序列集合中选择一个扰码序列来加扰数据包，在多个资源集合中选择一个资源集合来发送数据包；或者，0表示采用相关技术中的技术方案，1表示在第h次后重传数据包时从多个参考信号序列中选择一个参考信号序列同数据包一起发送，并在多个扰码序列集合中选择一个扰码序列来加扰数据包，在多个资源集合中选择一个资源集合来发送数据包，h为预定义值。
假设，基站配置该信息为1，并配置参考信号序列集合包括4个序列(序列编号为0到3)，序列集合根据4条时域正交码产生，在基础序列变换后获得，基础序列根据基站分配的频域带宽和NB-IoT R13(TS36.211)标准相关内容确定。
多条扰码序列参见TS36.211描述，扰码初始参数定义如下。
Figure PCTCN2019071278-appb-000005
k为多个扰码序列的索引，n为最大扰码序列索引对应的比特数，如：扰码 序列为4条，n为2，k取值为0,1,2,3。
UE A和UE B在基站配置的接入资源池上选择了相同的接入资源发送接入消息(PRACH)，基站在接入资源池上检测到接入消息，基站针对接入消息发送反馈消息，反馈消息包括上行定时调整信息和UE发送数据包时占用的资源的信息(参考TS36.213标准)，UE A和UE B在相同的资源(基站分配的资源)发送数据包给基站。
当UE A和UE B获知基站使能了新的传输方式时，UE A和UE B分别从4条参考信号序列集合和4条扰码序列集合选择一个参考信号序列同数据包一起发送，并在多个扰码序列集合中选择一个扰码序列来加扰数据包，在4个资源集合中选择一个资源集合来传输消息3；其中，参考信号序列和扰码序列、资源集合一一对应，如：参考信号序列索引k对应扰码序列索引k，对应资源集合索引为k。假设，UE A选择参考信号序列1和扰码序列1，资源集合索引1，UE B选择参考信号序列3和扰码序列3，资源集合索引3。
基站在分配的资源上分别按照序列集合中对每个序列和对应扰码序列、以及非正交资源解码数据包，当基站没有解码成功数据包，检测到参考信号序列1和参考信号序列3时，基站可以判断有两个UE在相同资源上发送数据包，基站发送用于指示终端重新发送数据包的重传调度信息，并在重传调度信息中携带对应目标传输方式的目标传输标识，在本实施例中，目标传输标识为资源集合索引信息(该信息为基站检测到的资源集合索引信息)。
UE A和UE B都会检测到基站发送的重传调度信息，当UE A检测到重传调度信息中携带的资源集合索引信息与自己上次传输选择的资源集合信息(资源集合索引1)一致时，认为该重传调度信息是发给自己，UE A按照该重传调度信息重新发送数据包，当UE A发现重传调度信息中携带的资源集合索引信息与自己上次传输选择的资源集合信息(资源集合索引1)不一致时，认为该重传调度信息不是发给自己，继续进行下行控制信息监测。UE B对于重传调度信息的处理过程与UE A相同。
这样，UE A和UE B根据基站调度，可以在不同的资源上发送数据包，避免了UE A和UE B持续在相同资源上发送数据包，提升解码数据包的成功率。
基站在分配的资源上分别按照序列集合中每个序列检测解码数据包，当基 站没有解码成功数据包，也没检测到参考信号序列时，基站发送重传调度信息，并在重传调度信息中携带资源集合信息设定为特定值，该特定值表示对任何UE都有效，这样，UE A和UE B都检测到该授权信息，UE A和UE B都按照重传调度信息重新选择参考信号序列和扰码序列，并在重传调度信息指示的位置上选择资源集合并发送数据包。
如果仍然无法解码数据包，重复上述过程。
如果参考信号序列数量和扰码序列数量、资源集合数量不等，基站需要按照多种可能进行检测；如：资源集合数量大于参考信号序列数量，则，一个参考信号序列会对应多个资源集合，基站需要针对一个参考信号序列对应多个资源集合进行检测。
实施例六
在本实施例中，目标传输方式为在数据包中加入参考信号序列、扰码序列和资源集合的传输方式，但在初次发送数据包时，仍然采用相关技术中的技术方案，在重新发送数据包时，才使用目标传输方式。在新无线系统(New Radio，NR)系统中，UE A和UE B在基站配置的接入资源池上选择了相同的接入资源发送接入接入消息(PRACH)，基站在接入资源池上检测到接入消息，基针对接入消息发送反馈消息，反馈消息包括上行定时调整信息和发送数据包时占用的资源的信息(参考TS38.213标准)，UE A和UE B在相同的资源(基站分配的资源)上发送数据包给基站。
当UE A和UE B获知基站使能了新的传输方式时，UE A和UE B按照反馈消息包括的发送数据包时占用的资源的信息在相同资源上采用相同传输方式发送数据包给基站。
基站按照单一传输方式(消息2指示的方式)检测数据包，未成功解码，发送重传调度信息。
UE A和UE B分别以目标传输方式发送数据包。
基站按照多种传输方式组合逐个检测，解码数据包，如果成功解码，则发送数据包的响应消息；如果仍未正确解码，则继续发送重传调度信息。
实施例七
在本实施例中，目标传输方式为在数据包中加入参考信号序列、扰码序列和资源集合的传输方式，但在初次发送数据包时，仍然采用相关技术中的技术方案，在重新发送数据包时，才使用目标传输方式。在NR系统中，UE A和UE B在基站配置的接入资源池上选择了相同的接入资源发送接入接入消息(PRACH)，基站在接入资源池上检测到接入消息，基针对接入消息发送反馈消息，反馈消息包括上行定时调整信息和发送数据包时占用的资源的信息(参考现有TS38.213标准)，UE A和UE B在相同的资源(基站分配的资源)上发送数据包给基站。
当UE A和UE B获知基站使能了新的传输方式时，UE A和UE B按照反馈消息包括的发送数据包时占用的资源的信息在相同资源上采用相同传输方式发送数据包给基站。
基站按照单一传输方式检测数据包，未成功解码，发送重传调度信息，并在重传调度信息中携带传输方式信息(设定为特定值，该特定值表示对任何UE都有效)，这样，UE A和UE B都检测到该重传调度信息，UE A和UE B都按照重传调度信息在多种传输方式中随机选择一种传输方式发送数据包。
UE A和UE B分别从多种传输方式(包括参考信号序列集合、扰码序列集合、多个资源集合中一个或多个)中选择一种传输方式发送数据包。
基站按照多种传输方式组合逐个检测，解码数据包，如果成功解码，则发送数据包的响应消息。
如果基站在多种传输方式组合逐个检测，当基站没有解码成功消息3，检测到传输方式信息(如：参考信号序列信息，或，资源集合信息)，基站可以判断有两个UE在相同资源上发送数据包，基站发送重传调度信息，并在重传调度信息中携带与传输方式对应的目标传输标识，在本实施例中，目标传输标识为参考信息信号序列索引信息(该信息为基站检测到参考信息信号序列索引信息)或资源集合索引信息(该信息为基站检测到的资源集合索引信息)。
UE A和UE B都会检测到基站发送的重传调度信息，当UE A检测到重传调度信息中携带的目标传输标识与自己上次传输选择的传输方式的传输标识一致时，认为该重传调度信息是发给自己，UE A按照该重传调度信息重新发送数据包，当UE A发现重传调度信息中携带的目标传输标识与自己上次传输选择的 传输方式的传输标识不一致时，认为该重传调度信息不是发给自己，继续进行下行控制信息检测。UE B对于重传调度信息的处理过程与UE A相同。
这样，UE A和UE B根据基站调度，可以在不同的资源上发送数据包，避免了UE A和UE B持续在相同资源上发送数据包，提升解码数据包的成功率。
基站在分配的资源上分别按照序列集合中每个序列检测解码数据包，当基站没有解码成功数据包，也没检测到参考信号序列时，基站发送重传调度信息，并在重传调度信息中携带资源集合信息设定为特定值，该特定值表示对任何UE都有效，这样，UE A和UE B都检测到该授权信息，UE A和UE B都按照重传调度信息重新选择参考信号序列和扰码序列，并在重传调度信息指示的位置上选择资源集合并发送数据包。
如果仍然无法解码数据包，重复上述过程。
对于支持多种覆盖等级场景，本公开提供的数据传输方式可以针对每个覆盖等级来配置数据包传输方式，或者，限制仅覆盖增强等级可以选择配置是否支持本公开提供的数据包传输方式；对于常规覆盖等级不支持本公开提供的数据包传输方式。
上述多个实施例中方案均可以应用于其他系统，如：LTE、eMTC、NB-IoT、NR等系统。
传输块大小包括多种数据包的传输块大小，每个UE可以随机从中选择一种大小，或者，根据自身需要发送业务，选择一个最匹配的大小传输；基站相应的按照多种大小可能进行检测。

本实施例提供一种终端，如图3所示，该终端3包括：选择模块31，设置 为从预设参考信息类型对应的参考信息集合中选择参考信息；处理模块32，设置为根据选择的参考信息和待发送数据包得到第一目标数据包。第一发送模块33，设置为向基站发送第一目标数据包。
在一实施例中，上述终端还包括：第一接收模块34，设置为接收基站发送的包含第一资源标识的调度信息；其中，调度信息用于指示终端发送待发送数据包，第一资源标识用于标识终端发送第一目标数据包时占用的资源。
在一实施例中，待发送数据包为终端接入网络过程中消息3对应的数据包，调度信息为终端接入网络过程中消息3对应的调度信息。
在一实施例中，待发送数据包为首次向基站发送的数据包，或者，待发送数据包为向基站重新发送的数据包。
在一实施例中，选择模块31是设置为：从预设参考信息类型对应的参考信息集合中以预设选择方式选择参考信息。
在一实施例中，第一接收模块34，还设置为接收基站发送的包含第二资源标识的第一重传调度信息；其中，第一重传调度信息用于指示终端重新发送待发送数据包，第二资源标识用于标识终端重新发送待发送数据包时占用的资源。
第二发送模块33，还设置为根据第二资源标识重新发送待发送数据包。
在一实施例中，第二发送模块33是设置为通过如下方式根据所述第二资源标识重新发送所述待发送数据包：从预设参考信息类型对应的参考信息集合中以预设选择方式重新选择参考信息；根据重新选择的参考信息和待发送数据包得到第二目标数据包；在第二资源标识对应的资源上向基站发送第二目标数据包。
在一实施例中，第一接收模块34，还设置为接收基站发送的包含参数信息对应的目标标识信息和第三资源标识的第二重传调度信息；其中，第二重传调度信息用于指示终端重新发送待发送数据包，第三资源标识用于标识终端重新发送待发送数据包时占用的资源。
第一发送模块33，还设置为如果第二重传调度信息中目标标识信息与自身发送第一目标数据包时选择的参考信息对应的标识信息相同，根据第三资源标识重新发送待发送数据包。
在一实施例中，第一接收模块34，还设置为接收基站发送的包含预设信息和第四资源标识的第三重传调度信息；其中，包含预设信息的第三重传调度信息用于指示接收到该重传调度信息的任何终端重新发送待发送数据包，第四资源标识用于标识终端重新发送待发送数据包时占用的资源。

在一实施例中，预设选择方式包括：随机选择方式，或者，根据终端对应的终端标识进行选择的方式，或者，根据终端的下行测量值进行选择的方式，或者，根据待传输数据包大小进行选择的方式。
在一实施例中，根据终端对应的终端标识进行选择的方式包括：根据终端标识与参考信息建立的映射关系进行选择的方式；根据终端的下行测量值进行选择的方式包括：根据终端的下行状态测量值与参考信息建立的映射关系进行选择的方式，或，根据下行路损测量值与参考信息建立的映射关系进行选择的方式，或，根据下行参考信号接收功率测量值与参考信息建立的映射关系进行选择的方式；根据待传输数据包大小进行选择的方式包括：根据数据包大小与参考信息建立的映射关系进行选择的方式。
在一实施例中，预设参考信息类型包括：参考信号序列、扰码序列、传输资源集合、传输块大小、相位旋转值、传输数据包的基准功率值和传输数据包的抬升功率值7种参考信息类型中至少一种；其中，第k种参考信息类型包括X k个参考信息，X k为正整数，k＝1、2、…、7。
本实施例提供的终端，从预设参考信息类型对应的参考信息集合中选择参考信息；根据选择的参考信息和待发送数据包得到第一目标数据包；向基站发送第一目标数据包。从本实施例可见，由于参考信息是终端在预设参考信息类型对应的参考信息集合中选择的，不同终端之间选择相同参考信息的概率较低，而当不同终端之间选择的参考信息不同时，数据包之间的干扰会大幅度地降低，从而提高了数据包被正确解码的概率。
在实际应用中，选择模块31、处理模块32、第一发送模块33和第一接收模块34均可由位于终端中的中央处理器(Central Processing Unit，CPU)、微处理器(Micro Processor Unit，MPU)、数字信号处理器(Digital Signal Processor，DSP)或现场可编程门阵列(Field Programmable Gate Array，FPGA)等实现。
