具体实施方式
本公开实施例发送侧确定与接收侧之间需要进行传输的多条无线链路；在确定的每条无线链路上向所述接收侧传输包含相同数据包的物理层传输块。由于本公开实施例在不同的无线链路上传输包含相同数据包的物理层传输块，能够充分利用接收侧连接的不同无线信道的资源，从而提高了实时性和高可靠性，相比目前无线通信系统能够更好支持机器类通信这类新应用对实时性和高可靠性。
下面结合说明书附图对本公开实施例作进一步详细描述。
如图1所示，本公开实施例一进行数据传输的方法包括：
步骤101、发送侧确定与接收侧之间需要进行传输的多条无线链路；
步骤102、所述发送侧在确定的每条无线链路上向所述接收侧传输包含相同数据包的物理层传输块。
本公开实施例提供了两种协议栈架构。
第一种：如图2所示，本公开实施例第一种协议栈架构示意图中，各条传输通道采用一套用户面高层协议栈(PDCP(Packet Data Convergence Protocol，分组数据聚合协议)、RLC(Radio Link Control，无线链路控制)、MAC(Medium Access Control，媒体接入控制)层)和一套物理层单元1(即主物理层单元)。用户面高层协议栈生成数据包(比如MAC PDU(Medium Access Control Packet Data Unit，媒体接入控制协议数据单元))；物理层处理单元1对数据包进行物理层处理(比如添加CRC(Cyclic Redundancy Check，循环冗余校验)、信道编码、复用、交织等)，形成多个包含相同数据包的物理层传输块，分发给不同无线链路的物理层单元2，由不同物理层单元2分别在不同空口链路发送。
具体的，所述发送侧中的主物理层单元确定与终端之间需要进行传输的多条无线链路；所述主物理层单元将用户面高层协议栈生成的数据包进行物理层处理，得到多个包含相同 数据包的物理层传输块；
所述主物理层单元将所有物理层传输块发送给与需要进行传输的多条无线链路对应的物理层单元，其中一个物理层传输块发送给一个物理层单元；
与需要进行传输的无线链路对应的物理层单元将包含相同数据包的物理层传输块通过对应的无线链路发送给终端。
对于第一种协议栈架构：所述主物理层单元为所有传输通道中的所有物理层单元对应的所述主物理层单元，需要进行传输的多条无线链路对应的物理层单元中不包括所述主物理层单元。
对于下行传输，网络侧实体有一套用户面高层协议栈(PDCP、RLC、MAC层)和一套物理层单元1(即主物理层单元)，用户面高层协议栈生成数据包(比如MAC PDU)；物理层处理单元1对数据包进行物理层处理(比如添加CRC、信道编码、复用、交织等)，形成多个包含相同数据包的物理层传输块，分发给每个小区的物理层单元2，由不同物理层单元2分别在不同空口链路发送。
对于上行传输，用户设备有一套用户面高层协议栈(PDCP、RLC、MAC层)和一套物理层单元1(即主物理层单元)，用户面高层协议栈生成数据包(比如MAC PDU)；物理层处理单元1对数据包进行物理层处理(比如添加CRC、信道编码、复用、交织等)，形成多个包含相同数据包的物理层传输块，分发给每个无线链路的物理层单元2，由不同物理层单元2分别在不同空口链路发送。
第二种：如图3所示，本公开实施例第二种协议栈架构示意图中，从多个无线链路中选择一个作为主无线链路，主无线链路对应的物理层处理单元为主物理层处理单元。用户面高层协议栈生成数据包(比如MAC PDU)；物理层处理单元1对数据包进行物理层处理(比如添加CRC、信道编码、复用、交织等)，形成多个包含相同数据包的物理层传输块，分发给不同无线链路的物理层单元2。
可以预先配置哪个无线链路作为主无线链路，比如可以选择连接可靠性较高、覆盖更广和具有签约功能的无线链路。例如LTE+WiFi，主无线链路一般是LTE。
具体的，所述发送侧中的主物理层单元确定与终端之间需要进行传输的多条无线链路；所述主物理层单元将用户面高层协议栈生成的数据包进行物理层处理，得到多个包含相同数据包的物理层传输块；
所述主物理层单元将所有物理层传输块发送给与需要进行传输的多条无线链路对应的物理层单元，其中一个物理层传输块发送给一个物理层单元；
与需要进行传输的无线链路对应的物理层单元将包含相同数据包的物理层传输块通过对应的无线链路发送给终端。
对于第二种协议栈架构：所述主物理层单元为所有传输通道中的所有物理层单元中的一个物理层单元，需要进行传输的多条无线链路对应的物理层单元中包括所述主物理层单元。
对于下行传输每个网络侧实体都有用户面高层协议栈和一套物理层单元，与主无线链路连接的网络侧实体的物理层单元作为主物理层单元。主物理层单元的用户面高层协议栈 生成数据包(比如MAC PDU)；主物理层单元对数据包进行物理层处理(比如添加CRC、信道编码、复用、交织等)，形成多个包含相同数据包的物理层传输块，通过网络侧实体之间的接口(比如如果是基站，则通过基站间接口，一般为X2接口)将物理层传输块的分发给不同的网络侧实体，每个物理层单元(包括主物理层单元)通过对应的无线链路发送。
对于上行传输终端中的每一条无线链路都有用户面高层协议栈和一套物理层单元(比如终端同时有两个无线链路，则每个无线链路都有用户面高层协议栈和一套物理层单元)，与主无线链路连接的物理层单元作为主物理层单元。主物理层单元的用户面高层协议栈生成数据包(比如MAC PDU)；主物理层单元对数据包进行物理层处理(比如添加CRC、信道编码、复用、交织等)，形成多个包含相同数据包的物理层传输块，通过设备内部的接口将物理层传输块的分发给不同的物理层单元，每个物理层单元(包括主物理层单元)的通过对应的无线链路发送。
可选地，每个包含相同数据包的物理层传输块的冗余版本全部相同或部分相同或全不相同。对于不同无线链路的冗余版本可采用协议固定的方式，如无线链路1、2、3的物理层传输冗余版本固定为0、2、1。
具体的，主物理层单元对数据包进行物理层处理(比如添加CRC、信道编码、复用、交织等)，形成多个包含相同数据包的物理层传输块时，如果需要每个包含相同数据包的物理层传输块的冗余版本全部相同，则形成多个冗余版本全部相同的包含相同数据包的物理层传输块；
如果需要每个包含相同数据包的物理层传输块的冗余版本部分相同，则形成多个冗余版本部分相同的包含相同数据包的物理层传输块；
如果需要每个包含相同数据包的物理层传输块的冗余版本全不相同，则形成多个冗余版本全不相同的包含相同数据包的物理层传输块。
其中，本公开实施例对MAC PDU进行物理层处理(信道编码、复用、交织等)，形成物理层传输块时，需要占用的资源可依据经验值或保守值或终端的主小区基站的分配资源确定。
在实施中，可以由网络侧通过高层信令(一般为RRC信令)为终端进行多路传输参数配置，配置可以包括但不限于下列中的一种或多种：参与多路传输的无线链路、主小区配置、反馈资源配置、最大传输次数。在实施中可以通过物理层单元进行配置，也可以通过其他单元进行配置。
可选地，若所述发送侧为网络侧，可以由主物理层单元通过高层信令(一般为RRC(Radio Resource Control，无线资源控制)信令)为终端进行多路传输参数配置，比如向所述终端发送下行调度命令，以指示所述终端在多条链路上接收数据。在实施中，如果是图2的协议栈架构，则主物理层单元可以通知终端的服务小区对应的物理层单元发送；如果是图3的协议栈架构，则主物理层单元可以通知终端的服务基站对应的物理层单元。
在进行调度时，调度命令除了由主物理层单元发送，还可以在终端的主小区上发送。一条调度命令指示多条无线链路上的传输。调度命令中的资源指示可以为：承载物理资源 块的无线链路采用相同的时频资源位置(此处频率资源位置指可用资源上的PRB(Physical Resource Block，物理资源块映射)，不指具体的子载波频率)，或调度命令对不同链路上的时频资源位置各自分别指示，即承载物理资源块的无线链路采用不同的时频资源位置。
若所述发送侧为终端，则终端根据所述网络侧的调度，确定与网络侧之间需要进行传输的多条无线链路。
可选地，所述主物理层单元在需要进行重传时，判断是否有重传次数达到对应的最大重传次数的无线链路；所述主物理层单元在确定有重传次数到达对应的最大重传次数的无线链路后，将所有物理层传输块发送给与需要进行传输的多条无线链路对应的物理层单元中除达到对应的最大重传次数的无线链路之外的物理层单元；其中，一个物理层传输块发送给一个物理层单元。
对于第二种协议栈架构，所述主物理层单元在需要进行重传时，判断自身的重传次数是否达到对应的最大重传次数；如果是，则停止自身的重传；否则，继续通过连接的无线链路发送一个包含相同数据包的物理层传输块。
每一条链路的最大重传次数可以全部相同，也可以部分相同，也可以全不相同。
如图4所示，本公开实施例二进行数据传输的方法包括：
步骤401、接收侧确定与发送侧之间需要进行传输的多条无线链路；
步骤402、所述接收侧在确定的每条无线链路上接收来自所述发送侧传输的包含相同数据包的物理层传输块。

可选地，所述接收侧在确定的每条无线链路上接收来自所述发送侧传输的包含相同数据包的物理层传输块之后，还包括：所述接收侧在至少一条无线链路上发送反馈信息。
在反馈时，可以只在一条无线链路上发送，比如可以是UE(终端)主小区的无线链路，或成功解码后在每条无线链路上都反馈ACK(正确应答指令)。
其中，若所述发送侧为网络侧，则所述接收侧为终端；若所述发送侧为终端，则所述接收侧为网络侧。
对于图2的协议栈架构，接收侧为网络侧或一个终端。接收侧为网络侧时，可以由分布式或集中式的物理层单元接收(每个物理层单元都可以是独立的实体)，再由主物理层集单元处理。
设备中的物理层单元通过与发送侧之间需要进行传输的多条无线链路中自身对应的无线链路接收物理层传输块，并将收到的物理层传输块上报给主物理层单元，其中每条无线链路上传输的物理层传输块中包含相同的数据包；具体的，物理层单元将收到的物理层传输块通过设备内接口上报给主物理层单元。
设备中的主物理层单元，用于接收与发送侧之间需要进行传输的多条无线链路中其他 无线链路对应的物理层单元上报的物理层传输块，并将自身收到的物理层传输块和其他的物理层单元上报的物理层传输块进行合并解码。
主物理层单元根据合并解码的结果，通知至少一个物理层单元在对应的无线链路发送反馈信息。
对于图3的协议栈架构，接收侧为多个网络侧实体或一个终端。
设备中的物理层单元通过与发送侧之间需要进行传输的多条无线链路中自身对应的无线链路接收物理层传输块，其中每条无线链路上传输的物理层传输块中包含相同的数据包；

若所述物理层单元不是主物理层单元，所述物理层单元将收到的物理层传输块上报给主物理层单元。如果接收侧是网络侧，则物理层单元将收到的物理层传输块通过设备间接口上报给主物理层单元，如果接收侧是终端，物理层单元将收到的物理层传输块通过设备内接口上报给主物理层单元。
若所述物理层单元是主物理层单元，所述物理层单元根据合并解码的结果，在通过自身对应的无线链路发送反馈信息和/或通知其他物理层单元在对应的无线链路发送反馈信息。
若所述接收侧为终端；所述接收侧确定与发送侧之间需要进行传输的多条无线链路，包括：所述终端根据所述网络侧的调度，确定与网络侧之间需要进行传输的多条无线链路。
在实施中，若所述接收侧为网络侧；接收侧可以通过高层信令(一般为RRC信令)为终端进行多路传输参数配置，配置可以包括但不限于下列中的一种或多种：参与多路传输的无线链路、主小区配置、反馈资源配置、最大传输次数。在实施中可以通过物理层单元进行配置，也可以通过其他单元进行配置。
可选地，若所述接收侧为网络侧，可以由主物理层单元通过高层信令(一般为RRC信令)为终端进行多路传输参数配置，比如向所述终端发送下行调度命令，以指示所述终端在多条链路上接收数据。在实施中，如果是图2的协议栈架构，则主物理层单元可以通知终端的服务小区对应的物理层单元发送；如果是图3的协议栈架构，则主物理层单元可以通知终端的服务基站对应的物理层单元。
一条调度命令指示多条无线链路上的传输。调度命令中的资源指示可以为：承载物理资源块的无线链路采用相同的时频资源位置(此处频率资源位置指可用资源上的PRB映射，不指具体的子载波频率)，或调度命令对不同链路上的时频资源位置各自分别指示，即承载物理资源块的无线链路采用不同的时频资源位置。
