Description

数据传输的方法和装置 技术领域
本发明涉及通信领域，尤其涉及数据传输的方法和装置。
背景技术
在第五代移动通信(5Generation，5G)技术中，对数据包的传输时延和可靠性等方面提出了更高的要求。特别是对于高可靠低时延通信(Ultra-reliable Low-latency Communication，URLLC)业务，需要较短的传输时延和较高的传输可靠性。在长期演进(Long Term Evolution，LTE)现有的数据传输机制中，发送端发送数据包后，需要等待接收端的发送的反馈信息，再根据反馈信息确定是否需要对数据包进行混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)重传。由于接收端进行数据包的数据检测以及发送反馈信息都需要一定的时间，这种“发送-等待-发送”的数据传输机制会造成较大的传输时延，同时由于一般发送端在单次传输数据包时，接收端发送的反馈信息携带否定(Negative ACKnowledgment，NACK)信息的概率较高，所以上述的数据传输机制也难以保证数据传输可靠性。
发明内容
本申请提出一种数据传输方法和装置，以提高数据传输的可靠性。
第一方面，本申请提供一种数据传输的方法，包括：在发送端接收到反馈信息之前，所述发送端连续向所述接收端发送携带相同信息的多个数据包，所述反馈信息携带用于指示所述接收端是否正确接收所述多个数据包中的至少部分数据包的指示信息；所述发送端接收所述接收端发送的所述反馈信息；所述发送端根据所述反馈信息传输后续的数据。
在该方案中，发送端可以连续向接收端发送携带相同信息的多个数据包，直到发送端接收到接收端发送的反馈信息，发送端再根据反馈信息确定后续的数据传输。这种数据传输机制中，由于发送端一直向接收端发送携带相同信息的数据包，可以提高数据传输的可靠性。
同时，上述数据传输机制，在接收端进行数据包的数据检测以及发送反馈信息的期间内，发送端可以一直向接收端发送携带相同信息的多个数据包， 可以缩短数据传输时延。例如，若接收端未正确接收第一个数据包时，后续携带相同信息的数据包已经由发送端发送至接收端了，接收端可以立即对后续携带相同信息的数据包重新检测，而无需像当前的数据传输机制一样，在接收端向发送端发送了反馈信息后，接收端需要等待发送端重新发送携带相同信息的数据包。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
应理解，本发明的技术方案，可以应用于各种通信系统，例如：全球移动通讯系统(Global System of Mobile communication，简称“GSM”)，码分多址(Code Division Multiple Access，简称“CDMA”)系统，宽带码分多址(Wideband Code Division Multiple Access Wireless，简称“WCDMA”)，通用分组无线业务(General Packet Radio Service，简称“GPRS”)，长期演进(Long Term Evolution，简称“LTE”)等。
还应理解，用户设备(User Equipment，简称“UE”)，也可称之为移动终端(Mobile Terminal)、移动用户设备等，可以经无线接入网(例如，Radio Access Network，简称“RAN”)与一个或多个核心网进行通信，用户设备可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置， 它们与无线接入网交换语言和/或数据。
基站，可以是GSM或CDMA中的基站(BTS，Base Transceiver Station)，也可以是WCDMA中的基站(Node B)，还可以是LTE中的演进型基站(eNB或e-NodeB，evolutional Node B)，本发明并不限定，但为描述方便，下述实施例以Node B为例进行说明。
图1示出了根据本发明实施的数据传输的方法的示意性流程图。图1所示的方法包括：
110，在发送端接收到反馈信息之前，所述发送端连续向所述接收端发送携带相同信息的多个数据包，所述反馈信息携带用于指示所述接收端是否正确接收所述多个数据包中的至少部分数据包的指示信息；
120，所述发送端接收所述接收端发送的所述反馈信息；
130，所述发送端根据所述反馈信息传输后续的数据。
具体地，发送端可以连续向接收端发送内容相同的多个数据包，直到发送端接收到接收端发送的反馈信息，该发送端根据该反馈信息传输后续的数据。
应理解，上述发送端可以为网络侧设备或者终端设备，上述接收端可以为网络侧设备或者终端设备，也就是说，上述发送端和接收端可以应用于端到端(Device-to-Device，D2D)通信系统中，上述发送端和接收端还可以应用于蜂窝通信系统中，本发明对此不作具体限定。
在该方案中，发送端可以连续向接收端发送携带相同信息的多个数据包，直到发送端接收到接收端发送的反馈信息，发送端再根据反馈信息确定后续的数据传输。这种数据传输机制中，由于发送端一直向接收端发送携带相同信息的数据包，可以提高数据传输的可靠性。
同时，上述数据传输机制，在接收端进行数据包的数据检测以及发送反馈信息的期间内，发送端可以一直向接收端发送携带相同信息的多个数据包，可以缩短数据传输时延。例如，若接收端未正确接收第一个数据包时，后续携带相同信息的数据包已经由发送端发送至接收端了，接收端可以立即对后续携带相同信息的数据包重新检测，而无需像当前的数据传输机制一样，在接收端向发送端发送了反馈信息后，接收端需要等待发送端重新发送携带相同信息的数据包。
可选地，作为一个实施例，所述发送端连续向所述接收端发送携带相同 信息的多个数据包，包括：所述发送端基于所述多个数据包各自对应的传输图样，连续向所述接收端发送所述多个数据包。
具体地，多个数据包中的每个数据包可以对应一种传输图样，该多个数据包中的每个数据包对应的传输图样可以相同，也可以不同。
在本方案中，由于携带相同信息的多个数据包中的每个数据包可以对应一种传输图样，使得发送端传输多个数据包的方式更加灵活。
可选地，作为一个实施例，所述发送端连续向接收端发送携带相同信息的多个数据包，包括：所述发送端基于至少两种传输图样向所述接收端发送携带相同信息的所述多个数据包。
具体地，发送端向接收端发送多个数据包时，可以基于不同的传输图样发送多个数据包。
例如，发送端基于两种不同的传输图样(以传输图样1以及传输图样2为例)向接收端发送3个携带相同信息的数据包，传输第一个数据包可以使用传输图样1，传输第二个数据包可以使用传输图样2，传输第三个数据包可以使用传输图样1；或者传输第一个数据包和第三个数据包可以使用传输图样1，传输第二个数据包可以使用传输图样2。
应理解，以上述发送端基于两种不同的传输图样(以传输图样1以及传输图样2为例)向接收端发送3个相同的数据包为例，本发明对传输多个数据包所使用的传输图样的顺序组合不作具体限定。
本方案中，发送端可以基于不同的传输图样向接收端发送携带相同信息多个数据包，由于传输图样的多样化可以提高数据包传输方式的多样化，以提高接收端正确接收数据包的概率。
图2示出了根据本发明实施的数据传输的方法的示意性流程图。图2所示的方法包括：
210，接收端接收发送端连续发送的携带相同信息的多个数据包；
220，所述接收端对所述多个数据包中的所述至少部分数据包进行检测，确定所述至少部分数据包的检测结果；
230，所述接收端根据所述至少部分数据包的检测结果，确定所述至少部分数据包的所述反馈信息，所述反馈信息携带用于指示所述接收端是否正确接收所述多个数据包中的至少部分数据包的指示信息；
240，所述接收端向所述发送端发送所述反馈信息。
具体地，接收端可以接收发送端连续发送的内容相同的多个数据包，并对多个数据包中的至少部分数据包进行检测，确定至少部分数据包的检测结果，再根据该检测结果，向发送端发送反馈信息，以通知发送端接收端是否正确接收该多个数据包携带的信息。
需要说明的是，接收端接收数据包和接收端对接收的数据包进行检测可以是两个相对独立的过程，也就是说接收端可以不对接收的多个数据包中的全部数据包进行检测。
若接收端向发送端发送了对个数据包中任一个数据包的反馈信息，该反馈信息携带ACK信息，接收端可以对发送端在没收到该ACK信息的时间段内发送的与多个数据包内容相同的数据包进行检测。
例如，发送端向接收端连续发送了3个携带相同信息的数据包，接收端对3个数据包中的第2个数据包向发送端发送了携带ACK信息的反馈信息，由于接收端发送反馈信息存在时延，此时发送端可能已经向接收端发送了第3个数据包，接收端可以接收第3个数据包，并对第3个数据包进行检测(例如，接收端需要获取通过第3个数据包对应的传输图样传输的第3个数据包的传输效果)；接收端也可以只接收第3个数据包，但不对该第3个数据包进行检测。
应理解，上述发送端可以为网络侧设备或者终端设备，上述接收端可以为网络侧设备或者终端设备，本发明对此不作具体限定。
在该方案中，发送端可以连续向接收端发送携带相同信息的多个数据包，直到发送端接收到接收端发送的反馈信息，发送端再根据反馈信息确定后续的数据传输。这种数据传输机制中，由于发送端一直向接收端发送携带相同信息的数据包，可以提高数据传输的可靠性。
同时，上述数据传输机制，在接收端进行数据包的数据检测以及发送反馈信息的期间内，发送端可以一直向接收端发送携带相同信息的多个数据包，可以缩短数据传输时延。例如，若接收端未正确接收第一个数据包时，后续携带相同信息的数据包已经由发送端发送至接收端了，接收端可以立即对后续携带相同信息的数据包重新检测，而无需像当前的数据传输机制一样，在接收端向发送端发送了反馈信息后，接收端需要等待发送端重新发送携带相同信息的数据包。
可选地，作为一个实施例，所述接收端接收所述发送端连续发送的携带 相同信息的多个数据包，包括：所述接收端基于所述多个数据包各自对应的传输图样，接收所述发送端连续发送的携带相同信息的多个数据包。
具体地，接收端接收发送端发送的内容相同的多个数据包中，每个数据包可以对应一种传输图样。
在本方案中，由于携带相同信息的多个数据包中的每个数据包可以对应一种传输图样，使得发送端传输多个数据包的方式更加灵活。
可选地，作为一个实施例，所述接收端接收发送端连续发送的携带相同信息的多个数据包，包括：所述接收端基于至少两种传输图样接收所述发送端发送的携带相同信息的所述多个数据包。
具体地，接收端接收发送端发送的多个数据包时，可以基于不同的传输图样接收多个数据包。
例如，接收端基于两种不同的传输图样(以传输图样1以及传输图样2为例)接收发送端发送的3个携带相同信息的数据包，接收端可以基于传输图样1接收第一个数据包，接收端可以基于传输图样2接收第二个数据包，接收端可以基于传输图样2接收第三个数据包。
应理解，以上述接收端基于两种不同的传输图样(以传输图样1以及传输图样2为例)接收发送端发送的3个相同的数据包为例，本发明对传输多个数据包所使用的传输图样的顺序组合不作具体限定。
本方案中，接收端可以基于不同的传输图样接收发送端发送的携带相同信息多个数据包，由于传输图样的多样化可以提高数据包传输方式的多样化，以提高接收端正确接收数据包的概率。
可选地，作为一个实施例，所述接收端对所述多个数据包中的至少部分数据包进行检测，包括：所述接收端对所述多个数据包中的每个数据包进行检测；或者所述接收端对所述多个数据包中的至少两个数据包进行联合检测。
具体地，接收端可以对发送端发送的多个数据包中的每个数据包进行检测，确定每个数据包的检测结果；或接收端可以对多个数据包中的一组数据包(即至少两个数据包)进行联合检测，确定一组数据包的一个检测结果。
应理解，接收端可以对上述多个数据包中的每个数据包进行单独检测，接收端还可以对上述多个数据包中的至少部分数据包进行联合检测，本发明对接收端对多个数据包的检测方法不做具体限定。
本方案中，接收端可以对发送端发送的多个数据包进行单独检测，或者 对多个数据包中的至少部分数据包进行联合检测，使得接收端检测数据包的方式多样化，以提高数据包检测的灵活性。
下面结合具体的方法流程详细介绍根据本发明实施例的数据传输的方法。图3示出了根据本发明另一实施的数据传输的方法的示意性流程图。应理解，图3示出了数据传输的方法的详细的步骤或操作，但这些步骤或操作仅是示例，本发明实施例还可以执行其他操作，或者图3中各操作的变形。此外，图3中的各个步骤可以按照与图3呈现的不同顺序来执行，并且有可能并非要执行图3中的全部操作。下面具体描述图3所示的方法步骤。
310，接收端接收调度信令。
具体地，发送端可以向接收端发送一条调度信令，指示接收端接收多个数据包；发送端还可以向接收端发送多条调度信息，由于多条调度信令与多个数据包一一对应，多条调度信令中的每条调度信令可以指示接收端接收与每条调度信令对应的数据包。
例如，当发送端为基站时，接收端可以接收基站发送的一条下行控制信令(Downlink Control Information，DCI)，该DCI用于指示该接收端接收发送端发送的多个数据包，也就是说，基站可以通过一条DCI调度接收端接收多个数据包；
接收端可以接收基站发送的多条DCI，多条DCI与多个数据包一一对应，多条DCI中的每条DCI用于指示接收端接收与每条DCI对应的数据包。也就是说，基站可以通过多条DCI调度接收端接收多个数据包，每条DCI用于调度接收端接收与该条DCI对应的数据包。
需要说明的是，当发送端为基站时，可以由发送端给接收端发送DCI；当发送端不是基站时，可以由基站向接收端发送DCI，也就是说，类似于D2D通信系统中，基站向接收端(终端)发送调度信息的情况。
320，发送端连续向接收端发送携带相同信息的多个数据包。
具体地，发送端连续地向接收端发送携带相同信息的多个数据包，直到发送端收到接收端发送的反馈信息。
上述携带信息相同的多个数据包可以指携带相同信息的多个数据包，也就是说多个数据包携带的目的IP地址、源IP地址、净载数据等部分的信息比特相同。
应理解，上述发送端可以为网络侧设备或者终端设备，上述接收端可以 为网络侧设备或者终端设备，本发明对此不作具体限定。
可选地，作为一个实施例，所述多个数据包使用各自对应的传输图样进行传输，所述多个数据包中每个数据包对应的传输图样是通过所述发送端和所述接收端预先约定的，或所述多个数据包中每个数据包对应的传输图样是由所述发送端通过信令发送至所述接收端的。
具体地，上述多个数据包中每个数据包对应的传输图样(pattern)可以是发送端和接收端预先约定好的。例如，传输多个数据包所使用的时频资源可以是连续子帧上的使用固定跳频图样的时频资源；上述多个数据包中每个数据包对应的传输图样是由所述发送端通过信令发送至所述接收端的，例如，发送端可以将每个数据包对应的传输图样携带在高层信令或者DCI中发送至接收端。
应理解，发送端可以基于一种传输图样对上述多个数据包进行传输，发送端可以基于多种传输图样对上述多个数据包进行传输，本发明对此不作具体限定。
可选地，作为一个实施例，所述发送端连续向接收端发送携带相同信息的多个数据包，包括：所述发送端基于至少两种传输图样向所述接收端发送携带相同信息的所述多个数据包。
例如，发送端基于两种不同的传输图样(以传输图样1以及传输图样2为例)向接收端发送3个相同的数据包，传输第一个数据包可以使用传输图样1，传输第二个数据包可以使用传输图样2，传输第三个数据包可以使用传输图样1；或者传输第一个数据包和第三个数据包可以使用传输图样1，传输第二个数据包可以使用传输图样2。
应理解，以上述发送端基于两种不同的传输图样(以传输图样1以及传输图样2为例)向接收端发送3个相同的数据包为例，本发明对传输多个数据包所使用的传输图样的顺序组合不作具体限定。
320，接收端向发送端发送反馈信息。
可选地，作为一个实施例，所述反馈信息携带用于指示所述接收端是否正确接收所述多个数据包中的第一数据包的指示信息，所述第一数据包为所述多个数据包中的任一个数据包。
图4是根据本发明另一实施例的以时分双工(Time Division Duplexing，TDD)方式进行上下行数据传输的示意图。下面以图4所示的以TDD方式 进行上下行数据传输为例对数据传输方法进行详细说明。假设发送端传输一个数据包，并接收该数据包对应的反馈信息需要较大的反馈时延。如图4所示，发送端通过下行链路(Down Link，DL)发送第一个数据包(图4中发送端发送第一个数据包1的时间)的反馈信息，可能在第N个数据包(图4中发送端发送第N个数据包1的发送时间)的传输时间之后，才能接收到(参见图4所示的发送端接收NACK消息的时间)。也就是说，发送端在传输数据时，不需要根据第一个数据包1的反馈信息，决定是否重传第二个数据包1，发送端可以在没收到第一个数据包1的反馈信息的时间段中，持续发送数据包1，直到接收到接收端通过上行链路(Up Link，UL)发送的第一个数据包1的反馈信息。若发送端接收的第一个数据包1的反馈信息是NACK信息，则发送端可以继续发送(重传)数据包1；如果发送端接收的第一个数据包1的反馈信息是ACK信息，则发送端可以停止发送数据包1，此时，该发送端可以发送新的数据包(参见图4中数据包2)。
可选地，作为一个实施例，所述反馈信息携带用于指示所述接收端是否正确接收所述多个数据包中的至少两个数据包的指示信息。
具体地，接收端需要接收发送端发送的携带相同信息的多个数据包之后，才能对该多个数据包进行联合检测，获取数据包的内容。例如，接收端需要接收发送端发送的多个数据包中的任意3个数据包之后，才能解析数据包的内容时，接收端向发送端发送的反馈信息可以是上述多个数据包中任意3个数据包的反馈信息，也就是说，当接收端正确接收了上述多个数据包中任意3个数据包时，接收端可以向发送端发送ACK信息；当接收端未正确接收上述多个数据包中任意3个数据包时，接收端可以向发送端发送NACK信息。
可选地，作为一个实施例，所述反馈信息携带用于指示所述接收端是否正确接收所述多个数据包携带的信息的指示信息。
具体地，携带相同信息的多个数据包可以理解为多次发送携带信息相同的数据包，所以从这一层面上来讲，反馈信息可以指示接收端是否正确接收了数据包携带的信息。
可选地，作为一个实施例，所述反馈信息携带所述多个数据包中的目标数据包对应的传输图样和/或所述目标数据包的传输序号。
图5是根据本发明另一实施例的以TDD方式进行上下行数据传输的示 意图。下面以图5所示的以TDD方式进行上下行数据传输为例对数据传输方法进行详细说明。如图5所示，发送端可以通过DL持续发送携带相同信息的多个数据包(参见图5所示的数据包1)，接收端可以根据多次传输该数据包(数据包1)的检测结果通过UL向发送端发送反馈信息。图5中以接收端是否正确接收发送端发送的3个数据包1为例进行说明，若接收端没有正确接收的发送端发送的3个数据包1时，接收端可以向发送端发送NACK信息作为反馈信息，接收端可以在该NACK信息中携带发送端发送上述3个数据包1中信道质量最差的一次传输的序号(参见图5所示的R2)，发送端可以基于该数据包对应的传输图样重传该序号对应的数据包，若接收端正确接收的发送端重传的序号为R2的数据包1时，接收端可以向发送端发送ACK信息，此时，发送端可以发送新的数据包(参见图5中数据包2)；若接收端正确接收的发送端发送的3个数据包1时，接收端可以向发送端发送ACK信息(图5中未示出)，此时，发送端可以发送新的数据包。
图6是根据本发明另一实施例的以频分双工(Frequency Division Duplexing，FDD)方式进行上下行数据传输的示意图。下面以图6所示的以FDD方式进行上下行数据传输为例对数据传输方法进行详细说明。如图6所示，发送端在可以在DL的子帧上持续多次(图6中以5次为例)发送携带相同信息的数据包(数据包1)。接收端在接收到连续的N个(图6中以3个为例)数据包后对这N个数据包进行联合检测。假设图6所示的第2个数据包1、第3个数据包1和第4个数据包1包括数据包1的所有HARQ冗余版本，也就是说，只有接收端接收到数据包1的这三个HARQ冗余版本后，才能对数据包1进行联合检测，所以当接收端通过UL向发送端发送反馈信息时，该反馈信息用于指示接收端是否正确接收数据包1的所有HARQ冗余版本，若发送端接收到NACK信息，可以继续发送数据包1；若发送端接收到ACK信息，可以停止发送数据包1，发送新的数据包数据包2。
可选地，作为一个实施例，所述反馈信息携带用于指示所述接收端是否正确接收所述发送端发送的所述多个数据包中的指定数据包的指示信息，所述指定数据包为与所述反馈信息具有预设时序关系的数据包。
具体地，反馈信息用于指示多个数据包中的指定数据包是否被接收端正确接收，其中反馈信息和指定数据包存在预设的时序关系，该预设时序关系可以指接收端向发送端发送反馈信息的时刻和接收端接收指定数据包的时 刻之间的固定时间段。
上述反馈信息和指定数据包之间的预设时序关系，以反馈信息和指定数据包之间间隔约定固定数目的传输时间间隔为例进行说明。应理解，本发明实施例的预设时序关系并不限于此。
假设反馈信息和指定数据包之间间隔约定传输时间间隔的固定数目为3，也就是说，反馈信息和指定数据包之间的传输时间间隔为3，当发送端接收到反馈信息时，该反馈信息用于指示在该反馈信息之前3个传输时间间隔的数据包是否被接收端正确接收。
可选地，作为一个实施例，所述预设时序关系为所述发送端和所述接收端预先约定的时序关系；或所述预设时序关系是由所述发送端通过信令发送至所述接收端的。
具体地，上述预设时序关系为发送端和接收端预先约定的时序关系，可以指发送端和接收端通过协议确定上述预先约定的时序关系，还可以指人为在发送端和接收端设置该预设时序关系。
上述预设时序关系是由发送端通过信令发送至接收端的，可以指发送端向接收端发送信令，该信令中携带上述预设时序关系。例如，当发送端为基站时，该发送端可以向接收端发送DCI，并在该DCI中携带上述预设时序关系。
应理解，当发送端和接收端都为终端时(可以理解为发送端和接收端之间进行D2D通信)，上述预设时序关系除了通过发送端发送至接收端之外，还可以通过基站向发送端和接收端分别发送，还可以由发送端发送至基站，再由基站发送至接收端，本发明对上述预设时序信息的配置方式不作具体限定。
330，发送端根据反馈信息传输后续的数据。
可选地，作为一个实施例，所述发送端根据所述反馈信息传输后续的数据，包括：所述发送端根据所述反馈信息，确定所述目标数据包对应的传输图样；所述发送端根据所述目标数据包对应的传输图样，确定传输后续的数据所使用的传输图样；所述发送端以所述传输后续数据包所使用的传输图样，传输所述后续的数据。

具体地，若接收端在反馈信息(NACK信息)中携带的目标数据包对应的传输图样和/或该目标数据包的传输序号，该目标数据包可以包括下列数据包中的任一种：未被所述接收端正确接收的数据包，传输所述多个数据包所使用的至少一个信道中信道质量最差的信道上传输的数据包，多个数据包中检测错误率最高的数据包。
若接收端在反馈信息(ACK信息)中携带的目标数据包对应的传输图样和/或该目标数据包的传输序号，该目标数据包可以包括传输所述多个数据包所使用的至少一个信道中信道质量最好的信道上传输的数据包，和/或多个数据包中检测错误率最低的数据包。
应理解，当上述目标数据包包括传输所述多个数据包所使用的至少一个信道中信道质量最差的信道上传输的数据包时，该目标数据包对应的传输图样和/或该目标数据包的传输序号也可以携带在ACK信息中，也就是说，该目标数据包虽然被接收端正确接收，但是传输该数据包所使用的信道的信道质量最差。本发明对不同类型的目标数据包携带在ACK信息或NACK信息中不作具体限定。
可选地，作为一个实施例，上述目标数据包还可以包括发送端传输多个数据包所使用的信道中，信道质量较差的信道上传输的数据包，也就是说接收端侧可以设置第一信道质量阈值，当传输数据包所使用的信道中任一信道的信道质量低于该信道质量阈值时，该信道上传输的数据包可以作为目标数据包。同理，上述目标数据包还可以包括发送端传输多个数据包所使用的信道中，信道质量较好的信道上传输的数据包，也就是说接收端侧还可以设置第二信道质量阈值，当传输数据包所使用的信道中任一信道的信道质量高于该信道质量阈值时，该信道上传输的数据包可以作为目标数据包。
应理解，上述第一信道质量阈值和第二信道质量阈值可以相同，或者上述第一信道质量阈值也可以低于第二信道质量阈值。
可选地，作为一个实施例，上述目标数据包还可以包括接收端检测的多个数据包中检测错误率较高的数据包。也就是说接收端侧可以设置第一检测 错误率阈值，当多个数据包的任一个数据包的检测错误率高于该第一检测错误率阈值时，该数据包可以作为目标数据包。同理，上述目标数据包还可以包括接收端检测的多个数据包中检测错误率较低的数据包。也就是说接收端侧可以设置第二检测错误率阈值，当多个数据包的任一个数据包的检测错误率低于该第二检测错误率阈值时，该数据包可以作为目标数据包。
应理解，第一检测错误率阈值和第二检测错误率阈值可以相同，或者第一检测错误率阈值也可以高于第二检测错误率阈值。
还应理解，上述反馈信息中携带的目标数据包的种类可以通过发送端和接收端预先约定的形式存储在发送端和接收端内，还可以在发送端和接收端内存储目标数据包对应的类型标识，在反馈信息中携带该数据包的类型标识，这样，发送端和接收端可以根据目标数据包对应的传输图样，调整后续数据包的传输图样，本发明对发送端和接收端获取目标数据包种类的方式不做具体限定。
可选地，作为一个实施例，所述发送端根据所述反馈信息传输后续的数据，包括：若所述反馈信息为ACK信息，所述发送端停止发送与所述多个数据包携带相同信息的数据包；若所述反馈信息为NACK信息，所述发送端传输与所述多个数据包携带相同信息的数据包。
需要说明的是，若反馈信息为ACK信息，发送端停止发送与所述多个数据包携带相同信息的数据包，发送端可以向接收端发送新的数据包(即与上述多个数据包携带不同信息的数据包)，发送端还可以结束向接收端传输数据，本发明对此不做具体限定。
可选地，作为一个实施例，所述方法还包括：若所述发送端发送所述多个数据包的数量大于或等于预设的阈值，所述发送端停止发送与所述多个数据包携带相同信息的数据包。
具体地，若发送端发送与多个数据包携带相同信息的数据包的次数大于或等于预设的发送次数，也就是说，若发送端发送与多个数据包内容相同的数据包的次数高于预设的发送次数，发送端停止发送与多个数据包内容相同的数据包，发送端可以向接收端发送新的数据包(即与上述多个数据包内容不同的数据包)，发送端还可以结束向接收端传输数据。
需要说明的是，当发送端向接收端发送多个数据包时，若发送端收到接收端发送的反馈信息为NACK信息(即携带NACK信息的反馈信息)，且当 发送端发送所述多个数据包的数量大于或等于预设的阈值时，发送端也可以停止向接收端发送与多个数据包内同相同的数据包。
可选地，作为一个实施例，所述传输图样由下列至少一种传输信息组成包括：混合自动重传请求HARQ冗余版本信息、频域资源信息、时域资源信息、赋形向量信息、子载波间隔信息、数据传输时间长度信息、导频序列信息和加扰序列信息。
上文结合图1和图6详细的说明了描述了本发明实施例的一种数据传输的方法，下面结合图7至图10，详细描述本发明实施例的一种数据传输的装置。应理解，图7至图10所示的装置能够实现图3中的各个步骤，为避免重复，在此不再详细赘述。
图7示出了根据本发明实施例的数据传输的装置的示意性框图。图7所示的装置700包括：第一发送模块710，接收模块720和第一处理模块730。

同时，上述数据传输机制，在接收端进行数据包的数据检测以及发送反馈信息的期间内，发送端可以一直向接收端发送携带相同信息的多个数据包，可以缩短数据传输时延。例如，若接收端未正确接收第一个数据包时，后续携带相同信息的数据包已经由发送端发送至接收端了，接收端可以立即对后续携带相同信息的数据包重新检测，而无需像当前的数据传输机制一样，在接收端向发送端发送了反馈信息后，接收端需要等待发送端重新发送携带相同信息的数据包。

在实现过程中，上述方法的各步骤可以通过处理器920中的硬件的集成逻辑电路或者软件形式的指令完成。结合本发明实施例所公开的数据传输的方法可以直接体现为硬件处理器执行完成，或者用处理器中的硬件及软件模块组合执行完成。软件模块可以位于随机存储器，闪存、只读存储器，可编程只读存储器或者电可擦写可编程存储器、寄存器等本领域成熟的存储介质中。该存储介质位于存储器910，处理器920读取存储器910中的信息，结合其硬件完成上述方法的步骤。为避免重复，这里不再详细描述。
在该方案中，发送端可以连续向接收端发送携带相同信息的多个数据包，直到发送端接收到接收端发送的反馈信息，发送端再根据反馈信息确定后续的数据传输。这种数据传输机制中，由于发送端一直向接收端发送携带相同信息的数据包，可以提高数据传输的可靠性。
同时，上述数据传输机制，在接收端进行数据包的数据检测以及发送反馈信息的期间内，发送端可以一直向接收端发送携带相同信息的多个数据包，可以缩短数据传输时延。例如，若接收端未正确接收第一个数据包时，后续携带相同信息的数据包已经由发送端发送至接收端了，接收端可以立即对后续携带相同信息的数据包重新检测，而无需像当前的数据传输机制一样，在接收端向发送端发送了反馈信息后，接收端需要等待发送端重新发送携带相同信息的数据包。
