具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
在本实施例中提供了一种数据传输处理方法，图1是根据本发明实施例的数据传输处理方法的流程图一，如图1所示，该流程包括如下步骤：
步骤S102，辅助用户设备检测传输节点发送给目标用户设备的数据调度信息，其中，该数据调度信息包括：该目标用户设备向该传输节点发送数据的调度信息；
步骤S104，该辅助用户设备根据该数据调度信息接收到该目标用户设备向该传输节点传输的数据。
通过上述步骤，辅助用户设备可以接收目标用户设备传输的数据，这样为辅助用户设备协助目标用户设备进行数据传输提供了实现的可能，至少为解决在目前的这种 数据传输处理方式下，数据传输性能有损失的问题提供了基础，提高了传输节点接收目标用户设备发送数据的性能。
作为一种可选的实施方式，由于辅助用户设备保存有目标用户设备的数据，辅助用户设备可以将接收到的该数据传输给传输节点，或者，在辅助用户设备确认不需要向该传输节点传输接收到的该数据的情况下，也可以清空接收到的该数据，可以节约该数据占用的空间。例如，辅助用户设备在可以检测到传输节点向目标用户设备发送的确认数据成功接收的信息ACK之后，确认不需要向该传输节点传输接收到的该数据，在确定不需要传输该数据之后，清空该数据，节约了储存空间。
在一个可选实施方式中，辅助用户设备中保存的数据可以用于重传，例如，传输节点指示需要对某数据进行重传，这有可能是因为目标用户设备的信道条件不好导致的，如果由目标用户设备重传，传输节点仍然可能接收不到该数据。此时就可以由辅助设备进行重传。即在该可选实施方式中，辅助用户设备可以检测传输节点发送给目标用户设备的重传数据调度信息或反馈信息，然后，根据该重传数据调度信息或反馈信息向该传输节点传输接收到的该数据。
在另一个可选实施方式中，辅助用户设备也可以在接收到数据之后直接发送给传输节点，这样目标用户设备和辅助用户设备均传输了相同的数据，可以保证传输节点正确接收到该数据。此时，辅助用户设备和目标用户设备可以使用相同的资源，即辅助用户设备在接收到该数据之后，与该目标用户设备在传输该数据相同的资源上重复传输接收到的该数据。例如，在该目标用户根据该数据调度信息在X个子帧上传输数据时，该辅助用户设备在接收到该数据后在该X个子帧中的Y个子帧上，与该目标用户设备在传输该数据相同的资源上重复传输接收到的该数据。
辅助用户设备向传输节点传输数据的方式可以有多种，在一个可选实施方式中，辅助用户设备向该传输节点传输接收到的该数据可以包括以下之一：该辅助用户设备按照与该目标用户设备传输或重传该数据的相同方式向该传输节点传输接收到的该数据；该辅助用户设备按照预先定义的方式向该传输节点传输接收到的该数据；该辅助用户设备按照该传输节点指示的方式传输该数据；该辅助用户设备不解码该数据直接转发给该传输节点。这些方式可以根据实际需要灵活选择。
在另一个可选的实施方式中，上述的数据调度信息还可以包括：辅助传输模式信息，其中，该辅助传输模式信息包括：所述辅助用户设备是否接收所述目标用户设备发送的数据，和或，所述辅助用户设备是否向所述传输节点传输所述接收到的数据。

步骤1-1，传输节点正确接收该目标用户设备发送的数据后，向目标用户设备发送ACK信息，辅助用户设备也可以监听到该信息，获知基站正确接收到该数据，清空接收到该数据；目标用户设备接收到ACK信息后清空该数据；
步骤1-2，传输节点没有正确接收该目标用户设备发送的数据后，向目标用户设备发送NACK信息或重传调度信息，目标用户设备在子帧n+k上重复传输该数据。
当辅助用户设备监听到该NACK信息或重传调度的情况下，获知基站没有正确接收到该数据；如果辅助用户设备正确接收了目标用户设备发送的数据，则，在子帧n+k上与目标用户设备相同的重传数据的资源上传输该数据；其中，该辅助用户设备传输该数据的方式与该目标用户设备重传该数据的方式相同，或者，该辅助用户设备按照预定义的方式或传输节点指示的方式传输该数据。其中，该传输方式具体包括：传输端口、导频序列选择、扰码标识、用户ID、数据映射方式中至少之一；不排除包括其他信息。如果辅助用户设备没有正确接收了目标用户设备发送的数据，则，在子帧n+k上接收目标用户设备的重传数据，合并该数据的首传数据和重传数据，解码该数据。

方式二，辅助用户设备在第一个子帧上接收到该目标用户设备发送的数据，辅助用户设备在这之后该X个子帧中Y个子帧上与该目标用户设备重复传输该数据相同的资源上传输该接收到未解码的数据，此时，该辅助用户设备相当于转发器，直接转发该用户设备数据，并不解码。
传输节点按照调度信息指示方式接收目标用户设备向传输节点发送的数据；该传输节点按照目标用户设备单独重辅传输传该数据、目标用户设备和辅助用户设备联合重复传输该数据进行解码该数据，或者，辅助用户设备帮助目标用户设备重传数据对于传输节点是透明的，传输节点仅按照目标用户设备重传该数据方式进行接收。
步骤2-1，如果传输节点正确接收该目标用户设备发送的数据后，向目标用户设备发送ACK信息，辅助用户设备也可以监听到该信息，获知基站正确接收到该数据，清空接收到该数据；目标用户设备接收到ACK信息后清空该数据；
步骤2-2，如果传输节点不能正确解码该数据，则，向目标用户设备发送NACK信息或重传调度信息，目标用户设备在X1个子帧上重复传输该数据。
辅助用户设备也可以监听到该NACK信息或重传调度，获知基站没有正确接收到该数据；如果辅助用户设备正确接收了目标用户设备发送的数据，则，在X1个子帧上与目标用户设备相同的重传数据的资源上传输该数据；其中，该辅助用户设备传输该数据的方式与该目标用户设备重传该数据的方式相同；如果辅助用户设备没有正确接收了目标用户设备发送的数据，则，按照上述方式一在X1个子帧上接收目标用户设备的重传数据，合并该数据的首传数据和重传数据，解码该数据，或者，按照上述方式二在X1个子帧上与目标用户设备相同的重传数据的资源上传输该接收到的未解码数据。
该传输节点按照目标用户设备单独重辅传输传该数据、目标用户设备和辅助用户设备联合重复传输该数据进行解码该数据，或者，辅助用户设备帮助目标用户设备重传数据对于传输节点是透明的，传输节点仅按照目标用户设备重传该数据方式进行接收；如果传输节点都不能正确解码该数据，则执行步骤2-2，如果传输节点可以正确解码该数据，则执行步骤2-1。
在本发明可选实施例中，辅助用户设备可以通过很多种方式监听并获取传输节点发送给目标用户设备的该数据调度信息以及传输节点传输给目标用户设备的数据，下面以几个比较典型的例子举例进行说明。
辅助用户设备接收到传输节点的配置信息，根据配置信息检测目标用户的下行控制信息，当检测到目标用户在子帧n上有新数据(首传数据包)发送给传输节点时，当辅助用户设备在子帧n上没有数据发送时，在子帧n下行控制信息指示的频域位置上接收目标用户设备发送的新数据(首传数据包)，当检测到传输节点发送给目标用户设备的NACK信息或重传下行控制信息后，在目标用户设备重传数据的资源上，向该传输节点传输接收到的目标用户设备发送的数据。其中，该配置信息包括以下至少之一：目标用户的ID信息，如：C-RNTI，SPS-RNTI等，目标用户的传输模式信息，承载下行控制信息的下行控制信道的类型，如：PDCCH，ePDCCH等。当使用ePDCCH传输该下行控制信息时，还包括ePDCCH相关的配置信息，如：ePDCCH所在子帧位置、OFDM起始符号位置、PRB set数量、PRB set内PRB数量及index、传输方式、扰码初始值参数、DMRS加扰初始值参数等中一个或多个。其中，检测该下行控制信息的搜索空间可以仅在公有搜索空间，或者，公有搜索空间和专有搜索空间，或者，仅在用户专有搜索空间；其中，检测该下行控制信息的时域区域可以是特定子帧集合，如：传输节点配置或预定义子帧，如：0、5、4、9中一个或多个等，也可以是所有子帧集合；其中，该下行控制信息对应的DCI Format可以是特定DCI Format，如：DCI Format0或DCI Format0X；其中，当采用ePDCCH时，该ePDCCH对应集合为特定值。
传输节点给目标用户设备和辅助用户设备配置组ID，目标用户设备发送数据对应的下行控制信息的专有搜索空间根据组ID确定，以保证目标用户设备和辅助用户设备可以在相同的搜索空间中检测下行控制信息，辅助用户设备可以获得目标用户设备的下行控制信息。其中，传输节点在发送目标用户设备对应的该下行控制信息使用目标用户设备的ID进行加扰，以标识该信息为目标用户设备信息，此时，辅助用户设备需要获得目标用户设备的ID，以便获得传输节点发送给目标用户设备的下行控制信息。另外，也可以使用组内ID加扰或在下行控制信息中标识该信息该的用户设备信息，其 中，组内ID可以预定义获得，或者，根据用户设备专有ID获得，或者，传输节点配置。其中，组ID和UE专有ID的使用包括以下方式至少之一：部分子帧集合采用组ID，部分子帧集合采用UE专有ID检测；定义候选资源集，资源集1采用UE专有ID，资源集2采用组ID；某个DCI Format采用组ID，某些DCI Format采用UE专有ID；组ID位于公有搜索空间，UE专有ID使用公有搜素空间和UE专有搜索空间；具体方式可以不限于上述描述。
基站在子帧n上传输上行调度信息给目标用户设备，辅助用户设备和目标用户设备都监听到该调度信息；目标用户设备在子帧n+4上根据基站发送的调度信息在相应资源上传输数据给基站，辅助用户设备在该资源上接收目标用户设备发送的数据；基站没有正确接收目标用户设备发送的数据，在子帧n+8上发送NACK或重传调度信息给目标用户设备，辅助用户设备和目标用户设备都监听到该信息(NACK或重传调度信息)，目标用户设备在接收到该信息后在子帧n+12上重传该数据，辅助用户设备也在相同重传资源上传输该重传数据。图10是根据本发明实施例的用户设备协作数据重传的示意图一，如图10所示，其中，用户设备辅助数据重传的模式，可以高层信令配置，或者，通过物理层信令动态指示，如：通过传输节点发送给目标用户设备的下行控制信息中信令指示，指示辅助用户设备是否需要辅助目标用户设备进行数据重传。
目标用户设备处于覆盖增强模式，假设，需要重传传输的子帧数量为8(也可以为其他值，如：4、6、10、12、16、20、40、80、100等)，基站在子帧n上传输上行调度信息给目标用户设备，辅助用户设备和目标用户设备都监听到该调度信息；目标用户设备在子帧n+4上根据基站发送的调度信息在连续的8个子帧上传输数据给基站，辅助用户设备在子帧n上开始接收目标用户设备发送的数据，在子帧n+4上开始辅助目标用户设备在相同资源上重传该数据；基站在子帧n上开始连续的8个子帧上自适应接收该数据。图11是根据本发明实施例的用户设备协作数据重传的示意图二，如图11所示，其中，用户设备辅助数据重传的模式，可以高层信令配置，或者，通过物理层信令动态指示，如：通过传输节点发送给目标用户设备的下行控制信息中信令指示，指示辅助用户设备是否需要辅助目标用户设备进行数据重传。
目标用户设备处于覆盖增强模式，假设，需要重传传输的子帧数量为6(也可以为其他值，如：4、6、10、12、16、20、40、80、100等)，基站在子帧n上传输上行调度信息给目标用户设备，辅助用户设备和目标用户设备都监听到该调度信息；目标用户设备在子帧n+4、n+8、n+9、n+10、n+11、n+12上根据基站发送的调度信息传输数据给基站，辅助用户设备在子帧n上开始接收目标用户设备发送的数据，在子帧n+8上开始辅助目标用户设备在相同资源上重传该数据；基站在子帧n+4、n+8、n+9、n+10、 n+11、n+12上自适应接收该数据。图12是根据本发明实施例的用户设备协作数据重传的示意图三，如图12所示，由于辅助用户设备接收数据到重传数据需要一定时间处理，目标用户设备在不连续的子帧上传输数据，可以使得辅助用户设备在目标用户设备第二个重传输数据的子帧开始辅助重传，尽快提升重传性能，减少目标用户设备的重传次数。其中，用户设备辅助数据重传的模式，可以高层信令配置，或者，通过物理层信令动态指示，如：通过传输节点发送给目标用户设备的下行控制信息中信令指示，指示辅助用户设备是否需要辅助目标用户设备进行数据重传。
上述实施例中辅助用户设备可以是终端，也可以是辅助传输节点，如：微基站、小小区基站、家庭基站、中继节点等，具体过程与辅助终端辅助数据传输过程相同，仅是辅助传输节点代替辅助用户设备。
通过上述可选实施例，辅助终端协助主终端进行数据重传，提升数据传输性能，提高资源使用效率，解决特定场景下现有数据传输方案导致系统资源效率下降的问题，降低数据传输延时，提升数据传输可靠性。
工业实用性：通过上述描述可知，采用辅助终端协助主终端进行数据重传，可以提升数据传输性能，提高资源使用效率。
