Description

数据传输的方法和装置 技术领域
本申请涉及通信领域，特别涉及通信领域中的一种数据传输的方法和装置。
背景技术
为了提高数据传输的可靠性，同时降低由重新传输带来的传输时延，第五代移动通信系统(the fifth generation，5G)支持数据的重复传输，即允许发送端发送同一数据包的多个相同或不相同的冗余版本。发送端在每次发送数据包之前，不必等待接收端对该数据包的反馈，例如混合自动重传请求(hybrid automatic repeat request，HARQ)的否定应答(negative acknowledgement，NACK)反馈。
重复传输次数是由网络设备为终端设备配置的。在一些需要保证上行覆盖的场景中，例如海量机器类通信(massive machine-type communications，mMTC)场景中，网络设备通常会为终端设备配置较大的重复传输次数，虽然这样能够提升覆盖，但是也不可避免地增加了终端设备的功耗，同时也会给其他终端设备带来干扰。
发明内容
本申请提供一种数据传输的方法和装置，能够减少数据的重复传输次数，降低终端设备的功耗，节省传输资源，且能够维持较高的时间分集增益。

本申请实施例的数据传输的方法，通过终端设备与网络设备在时域不连续的N个重复传输时机上重复传输第一数据，将第一数据的重复传输次数在已配置的K次的基础上减少到了N次，在保证第一数据可靠传输的同时，能够减少第一数据的重复传输次数，降低终端设备的功耗，节省传输资源，且由于N个重复传输时机在时域上不连续，使得第一数据的重复传输总的时间跨度较大，能够维持较高的时间分集增益，从而提高系统性能。
本申请实施例仅以终端设备为执行主体进行了描述，但应理解，上述终端设备可以是终端设备本身，也可以是终端设备中的装置(例如，芯片、处理器、或芯片系统中的一种或多种)，本申请对此不作限定。
在本申请中，两个重复传输时机在时域上连续是指：两个重复传输时机所占用的时域资源在时间上连续。两个重复传输时机在时域上不连续是指：两个重复传输时机所占用的时域资源在时间上不连续。
对于多个重复传输时机而言，该多个重复传输时机在时域上连续是指：在多个重复传输时机中，任意相邻的两个重复传输时机在时域上连续。多个重复传输时机在时域上不连 续是指：在多个重复传输时机中，至少存在相邻的两个重复传输时机在时域上不连续。相邻的两个重复传输时机是指：在该相邻的两个重复传输时机之间的时域资源上不存在属于该多个重复传输时机中的重复传输时机。
应理解，若多个重复传输时机中的所有相邻的两个重复传输时机在时域上均不连续，则可以称为“该多个重复传输时机在时域上全部不连续”；若多个重复传输时机中存在一部分相邻的两个重复传输时机在时域上不连续，另一部分相邻的两个重复传输时机在时域上连续，则可以称为“该多个重复传输时机在时域上部分不连续”。“多个重复传输时机在时域上全部不连续”和“多个重复传输时机在时域上部分不连续”都可以理解为多个重复传输时机在时域上不连续。

在第一种可能的实现方式中，上述第二信息可以指示K个重复传输时机中进行重复传输的N个重复传输时机。对于未指示的其他K-N个重复传输时机，终端设备不在其他K-N个重复传输时机上传输数据。这种方式更适用于N小于K-N的场景，即需要指示出数量较少的N个重复传输时机，这样有利于节省网络设备的信令开销，但本申请实施例对该实现方式的应用场景并不作限定。
在第二种可能的实现方式，上述第二信息可以指示K个重复传输时机中静默(mute)或取消(drop)传输的K-N个重复传输时机。对于未指示的其他N个重复传输时机，终端设备在该N个重复传输时机上传输数据。这种方式更适用于K-N小于N的场景，即需要指示出数量较少的N-K个重复传输时机，这样有利于节省网络设备的信令开销，但本申请实施例对该实现方式的应用场景并不作限定。
上述第二信息可以是网络设备通过高层信令和/或物理层信息配置的。例如，网络设备可以通过RRC信令、DCI、或者MAC CE中的一种或多种以显式的方式将该第二信息发送给终端设备的。通过显式方式确定N个重复传输时机，可以节省终端设备的处理时延，可以提高终端设备的处理速度，提高数据传输效率。

在另一种可能的实现方式中，上述分布模式可以通过公式来体现，上述一个或多个参数可以是公式本身，或者公式的索引，或者公式中的参数。
结合第一方面，在第一方面的某些实现方式中，所述第二信息携带在节能信道或节能信号中，所述节能信道或节能信号用于触发醒来、触发睡眠、触发跨载波调度、触发信道状态信息CSI报告、指示物理下行控制信道PDCCH监听周期、或指示跳过PDCCH监听中的一个或多个。
在本申请实施例中，第二信息携带在节能信道或节能信号中，终端设备和网络设备可以在持续时间(on duration)阶段减少重复传输次数，即将重复传输次数从K次减少到N次，更进一步降低终端设备的功耗，节省传输资源。

第二方面，提供了另一种数据传输的方法，包括：网络设备发送第一信息，所述第一信息用于配置K个重复传输时机；所述网络设备在所述K个重复传输时机中的N个重复传输时机上重复传输第一数据，所述N个重复传输时机在时域上不连续，K为大于1的整数，N为大于或等于1、且小于K的整数。
本申请实施例的数据传输的方法，通过终端设备与网络设备在时域不连续的N个重复传输时机上重复传输第一数据，将第一数据的重复传输次数在已配置的K次的基础上减少到了N次，在保证第一数据可靠传输的同时，能够减少第一数据的重复传输次数，降低终端设备的功耗，节省传输资源，且由于N个重复传输时机在时域上不连续，使得第一数据的重复传输总的时间跨度较大，能够维持较高的时间分集增益，从而提高系统性能。

重复传输是指允许发送端在连续或非连续的时域资源上发送同一数据包的多个相同或不相同的冗余版本。发送端在每次发送数据包之前，不必等待接收端对该数据包的反馈，例如混合自动重传请求(hybrid automatic repeat request，HARQ)的否定应答(negative acknowledgement，NACK)反馈。重复传输次数是由网络设备为终端设备配置的。在一些需要保证上行覆盖的场景中，例如海量机器类通信(massive machine-type communications，mMTC)场景中，网络设备通常会为终端设备配置较大的重复传输次数，虽然这样能够提升覆盖，但是也不可避免地增加了终端设备的功耗，同时也会给其他终端设备带来干扰。
有鉴于此，本申请实施例提出了一种数据传输的方法，能够减少数据的重复传输次数，降低终端设备的功耗，节省传输资源，且能够维持较高的时间分集增益。
为了便于理解本申请实施例，先简要说明如下。
在本申请实施例中，高层信令例如可以是无线资源控制(radio resource control，RRC)信令，也可以是其他高层信令，例如媒体接入控制(media access control，MAC)控制元素(control element，CE)。物理层信息例如可以是下行控制信息(downlink control information，DCI)，也可以是其他物理层信息，本申请对此不做限定。本申请实施例的物理层信息可以由物理信道承载，该物理信道例如可以是物理下行控制信道(physical downlink control channel，PDCCH)、或物理下行共享信道(physical downlink shared channel，PDSCH)等。
在本申请实施例中，“用于指示”可以表示用于直接指示或用于间接指示，也可以包括显式指示或隐式指示。将某一信息(如下文所述的用于指示重复传输时机的信息)所指示的信息称为待指示信息，则具体实现过程中，对待指示信息进行指示的方式有很多种，例如但不限于，可以直接指示待指示信息，如指示待指示信息本身或者指示该待指示信息的索引等。也可以通过指示其他信息来间接指示待指示信息，其中该其他信息与待指示信息之间存在关联关系。还可以指示待指示信息的一部分，而待指示信息的其他部分则是预定义的。例如，还可以借助预定义(例如协议规定)是否存在某个信元来实现对待指示信息的指示，从而在一定程度上降低指示开销。
下面将结合附图详细说明本申请提供的各个实施例。
图2示出了本申请实施例的数据传输的方法200的示意性流程图。该方法200可以应用于图1所示的通信系统100，但本申请实施例不限于此。
S210，网络设备发送第一信息，则对应地，终端设备接收该第一信息，该第一信息用于配置K个重复传输时机；
S220，该终端设备与该网络设备在上述K个重复传输时机中的N个重复传输时机上重复传输第一数据，其中，该N个重复传输时机在时域上不连续，K为大于1的整数，N为大于或等于1、且小于K的整数。
本申请实施例的数据传输的方法，通过终端设备与网络设备在时域不连续的N个重复传输时机上重复传输第一数据，将第一数据的重复传输次数在已配置的K次的基础上减少到了N次，在保证第一数据可靠传输的同时，能够减少第一数据的重复传输次数，降低终端设备的功耗，节省传输资源，且由于N个重复传输时机在时域上不连续，使得第一数据的重复传输总的时间跨度较大，能够维持较高的时间分集增益，从而提高系统性能。
上述终端设备与网络设备传输第一数据，可以包括终端设备向网络设备发送上行数据，网络设备接收该上行数据，此时，终端设备作为发送端，网络设备作为接收端；也可以包括网络设备向终端设备发送下行数据，终端设备接收该下行数据，此时，终端设备作为接收端，网络设备作为发送端，本申请实施例对此不作限定。
应理解，一次重复传输所采用的时域资源称为一个重复传输时机(transmission occasion，TO)。在本申请中，两个重复传输时机在时域上连续是指：两个重复传输时机所占用的时域资源在时间上连续。两个重复传输时机在时域上不连续是指：两个重复传输时机所占用的时域资源在时间上不连续。
对于多个重复传输时机而言，该多个重复传输时机在时域上连续是指：在多个重复传输时机中，任意相邻的两个重复传输时机在时域上连续。多个重复传输时机在时域上不连续是指：在多个重复传输时机中，至少存在相邻的两个重复传输时机在时域上不连续。相邻的两个重复传输时机是指：在该相邻的两个重复传输时机之间的时域资源上不存在属于该多个重复传输时机中的重复传输时机。
应理解，若多个重复传输时机中的所有相邻的两个重复传输时机在时域上均不连续，则可以称为“该多个重复传输时机在时域上全部不连续”；若多个重复传输时机中存在一部分相邻的两个重复传输时机在时域上不连续，另一部分相邻的两个重复传输时机在时域上连续，则可以称为“该多个重复传输时机在时域上部分不连续”。“多个重复传输时机在时域上全部不连续”和“多个重复传输时机在时域上部分不连续”都可以理解为多个重 复传输时机在时域上不连续。
因此，上述“N个重复传输时机在时域上不连续”，是指在N个重复传输时机中，至少存在相邻的两个重复传输时机在时域上不连续。换句话说，上述N个重复传输时机在时域上可以是全部不连续，或者是部分不连续，本申请实施例对此不作限定。
还应理解，上述“第一信息”也可以称为“第一配置信息”或其他名称，第一信息可以是通过高层信令和/或物理层信息配置的。示例性地，在一种可能的上行免授权传输的配置方式中，网络设备可以通过高层信令发送第一信息，该第一信息可以包括周期信息、时域资源信息、频域资源信息、解调参考信号、调制编码方案、冗余版本、重复传次数K等中的一个或多个。终端设备可以接收该第一信息，并在配置的时域资源和频域资源上，按照配置的周期信息，周期性地传输上行数据，以达到半静态传输效果。其中，在一个周期中，所传输的数据可以按照第一信息配置的冗余版本重复传输K次。
上述第一信息所配置的K个重复传输时机可以是在时域上连续的，或者在时域上不连续的，本申请实施例对此不作限定。
图3和图4分别示出了本申请的数据传输方法所采用的两种可能的重复传输时机的分布示意图。在图3中，K个重复传输时机在时域上是连续的，假设K＝8，N＝4，对应重复传输时机的标识可以为0～7，而N个重复传输时机为在K个重复传输时机上每间隔一个重复传输时机传输一次，对应重复传输时机的标识可以为0、2、4、6。在图4中，K个重复传输时机在时域上是不连续的，假设K＝8，N＝4，对应重复传输时机的标识可以为0、1、3～5、9-11，而N个重复传输时机为在K个重复传输时机上每间隔一个重复传输时机传输一次，对应重复传输时机的标识可以为0、3、5、10。
由于上述图3和图4中N个重复传输时机均是每间隔一个重复传输时机传输一次，该N个重复传输时机在时域上是全部不连续的。图5示出了本申请的数据传输方法所采用的另一种可能的重复传输时机的分布示意图。在图5中，K个重复传输时机在时域上是不连续的，假设K＝8，N＝4，对应重复传输时机的标识可以为0、1、3～5、9-11，而N个重复传输时机为在K个重复传输时机上每间隔两个重复传输时机传输一次，对应重复传输时机的标识可以为0、1、4、5、10、11。因此，该N个重复传输时机在时域上是部分不连续的。
虽然本申请实施例示出了终端设备和网络设备之间的数据传输流程，但应理解，本申请实施例的方法不限定此场景，其还可以应用到终端设备和终端设备之间的数据传输，例如侧行链路传输，本申请实施例对此不作限定。示例性地，本申请实施例的方法还可以应用于车到X(vehicle to X，V2X)、设备到设备(device-to-device，D2D)的通信(例如，UE与UE之间的通信)、中继通信等其他通信中。
在终端设备和终端设备之间进行数据传输的场景下，上述第一信息可以是网络设备为本申请实施例中的终端设备配置的，也可以是其他终端设备为本申请实施例中的终端设备配置的，此处不作限定。
在本申请实施例中，网络设备可以通过多种方式向终端设备指示K个重复传输时机中的N个重复传输时机。下面主要分显式指示和隐式指示两种情况进行说明。
情况1、网络设备通过显式指示的方式，使终端设备获得上述N个重复传输时机。
作为一个可选的实施例，所述方法还包括：所述网络设备发送第二信息，则对应地， 所述终端设备接收第二信息，该第二信息用于指示所述N个重复传输时机上的重复传输。
在第一种可能的实现方式中，上述第二信息可以指示K个重复传输时机中进行重复传输的N个重复传输时机。对于未指示的其他K-N个重复传输时机，终端设备不在其他K-N个重复传输时机上传输数据。这种方式更适用于N小于K-N的场景，即需要指示出数量较少的N个重复传输时机，这样有利于节省网络设备的信令开销，但本申请实施例对该实现方式的应用场景并不作限定。
在第二种可能的实现方式，上述第二信息可以指示K个重复传输时机中静默(mute)或取消(drop)传输的K-N个重复传输时机。对于未指示的其他N个重复传输时机，终端设备在该N个重复传输时机上传输数据。这种方式更适用于K-N小于N的场景，即需要指示出数量较少的N-K个重复传输时机，这样有利于节省网络设备的信令开销，但本申请实施例对该实现方式的应用场景并不作限定。
应理解，终端设备可以获取网络设备所采用的指示方式是上述两种可能的实现方式中的哪一种。示例性地，网络设备和终端设备可以通过信令指示或预定义的方式，确定采用上述第一种实现方式或者第二种实现方式，这种方式实现简单，无需终端设备进行过多判断，降低终端设备的负担，有利于节省终端设备的功耗。示例性地，网络设备和终端设备也可以根据上述N和K-N的取值，确定采用上述第一种实现方式或者第二种实现方式，这种方式更加灵活，更有利于节省网络设备的信令开销。
上述第二信息可以是网络设备通过高层信令和/或物理层信息配置的。例如，网络设备可以通过RRC信令、DCI、或者MAC CE中的一种或多种以显式的方式将该第二信息发送给终端设备的。
作为一个可选的实施例，所述第二信息用于指示比特位图，所述比特位图包括K个比特，所述K个比特中包括N个0或N个1，所述N个0或N个1用于指示所述N个重复传输时机。
示例性地，K个比特中包括N个0，该N个0用于指示上述N个重复传输时机。以图3和图4为例，上述第二信息所指示的K个比特可以为01010101。或者，K个比特中包括N个1，该N个1用于指示上述N个重复传输时机。以图3和图4为例，上述第二信息所指示的K个比特可以为10101010。
需要说明的是，上述第二信息可以就是上述比特位图，或者，上述第二信息可以是经过编码、压缩、映射等方式中的一种或多种对上述比特位图处理后的结果，或者，上述第二信息可以是上述比特位图在预先定义的多个比特位图中的索引，或者，上述第二信息可以包括预先定义的比特位图集合的索引以及上述比特位图在预先定义的比特位图集合中的索引。
作为一个可选的实施例，所述第二信息用于指示一个或多个参数，所述一个或多个参数与所述N个重复传输时机存在对应关系。
在一种可能的实现方式中，网络设备和终端设备可以预先配置或者预定义上述N个重复传输时机的分布模式(pattern)，其中一种分布模式对应一个索引(index)。在该实施例中，上述一个或多个参数可以是分布模式的索引，终端设备根据该一个或多个参数，获得N个重复传输时机的分布模式，即可确定N个重复传输时机。因此，一个或多个参数与N个重复传输时机存在对应关系。
表一示出了本申请实施例的一种可能的分布模式的示例。在表一中，索引1对应的分布模式为每间隔1个重复传输时机，静默1个重复传输时机，共静默K-N个重复传输时机，索引2对应的分布模式为每间隔2个重复传输时机，传输1个重复传输时机，共重复传输N个重复传输时机，索引3对应的分布模式为每间隔2个重复传输时机，静默2个重复传输时机，共静默K-N个重复传输时机，还可以预先配置或预定义其他分布模式，例如每间隔3个重复传输时机，传输1个重复传输时机；或者，每间隔1个重复传输时机，传输2个重复传输时机等等，此处不再一一列举。以图3和图4为例，若采用本实施例中的参数，第二信息可以为索引1。
表一
Figure PCTCN2019102046-appb-000001
应理解，上述索引的取值仅仅是示例性说明，并不对本申请实施例的范围构成限定，例如，索引的取值也可以从0开始。
在另一种可能的实现方式中，上述分布模式可以通过公式来体现，上述一个或多个参数可以是公式本身，或者公式的索引，或者公式中的参数。
以图3和图4为例，预先配置或预定义的公式为f(n)＝n mod 2，n∈{1,2,…,K}，n＝1时对应K个重复传输时机中的第一个重复传输时机，n＝2时对应K个重复传输时机中的第二个重复传输时机，依次类推，n＝K时对应K个重复传输时机中的第K个重复传输时机，f(n)＝1表示传输，f(n)＝0表示不传输。在这种情况下，网络设备可以通过上述第二信息指示该公式，终端设备依次计算K个重复传输时机中的每个重复传输时机对应的f(n)，根据计算结果确定上述N个重复传输时机。
在一种可能的实现方式中，网络设备可以通过上述第二信息中的参数指示公式，例如f(n)＝n mod 2。
在另一种可能的实现方式中，可以预先配置或预定义公式，例如f(n)＝n mod l，参数l为正整数，网络设备可以通过第二信息中的参数指示该公式中的参数l，例如指示参数l＝2，使得终端设备获得公式f(n)＝n mod 2。
在另一种可能的实现方式中，可以预先配置或预定义多个公式，每个公式对应一个索引，例如f(n)＝n mod 2的索引为1，f(n)＝n mod 3的索引为2等，网络设备可以通过上述第二信息中的参数指示公式f(n)＝n mod 2的索引1，使得该终端设备获得公式f(n)＝n mod 2。
应理解，上述公式仅仅是示例性说明，f(n)＝n mod 2可以替换为其他一个或多个公式，本申请实施例对此不作限定。
此外，终端设备可以预先获取所采用的公式的取值的含义，例如，对于公式 f(n)＝n mod 2，f(n)＝1表示传输，f(n)＝0表示不传输，或者，f(n)＝0表示传输，f(n)＝1表示不传输。又例如，对于公式f(n)＝n mod 3，f(n)＝2表示传输，f(n)＝1表示传输，f(n)＝0表示不传输，或者，f(n)＝2表示传输，f(n)＝1表示不传输，f(n)＝0表示不传输，或者f(n)＝2表示不传输，f(n)＝1表示不传输，f(n)＝0表示传输等。网络设备可以通过信令为终端设备配置上述取值的含义，也可以预定义上述取值的含义，本申请实施例对此不作限定。
作为一个可选的实施例，所述第二信息携带在节能信道或节能信号中，所述节能信道或节能信号用于触发醒来、触发睡眠、触发跨载波调度、触发信道状态信息CSI报告、指示物理下行控制信道(physical downlink control channel，PDCCH)监听周期、或指示跳过PDCCH监听中的一个或多个。
节能信道或节能信号是由网络设备发送给终端设备的。示例性地，如图6所示，终端设备可以接收网络设备发送的节能信号(power saving signal，PoSS)或节能信道(power saving channel，PoSC)，根据该PoSS或PoSC，在接下来的一个非连续接收(discontinuous reception，DRX)周期中的持续时间(on duration)阶段，执行低功耗收发信息等操作；在非活动(inactivity)阶段，处于非活跃状态，例如不监听PDCCH、进入休眠状态等，以节省终端设备的功耗。上述非连续接收DRX指的是在一个配置的周期(称为DRX周期)内的一部分时间上终端设备处于活跃状态，处于该活跃状态的终端设备与网络设备保持连接状态。在该DRX周期内的另一部分时间上终端设备处于非活跃状态，处于该非活跃状态的终端设备可以在少部分时间上监听网络设备的控制信息、或不监听网络设备的调度信息、或者不接收其他网络单元发送的数据、或者不向其他网络单元发送数据等，从而达到节省终端设备功耗的目的。
在本申请实施例中，第二信息携带在PoSS或PoSC中，终端设备和网络设备可以在on duration阶段减少重复传输次数，即将重复传输次数从K次减少到N次，更进一步降低终端设备的功耗，节省传输资源。
情况2、网络设备通过隐式指示的方式，使终端设备确定上述N个重复传输时机。
作为一个可选的实施例，所述方法还包括：所述网络设备发送控制信息，则对应地，所述终端设备接收控制信息，所述控制信息对应的无线网络临时标识(radio network temporary identifier，RNTI)、搜索空间(search space，SS)或控制资源集合(control resource set，CORESET)中的一个或多个与所述N个重复传输时机存在对应关系。
示例性地，可以预先配置或预定义不同的RNTI、不同的SS或不同的CORESET中的一个或多个，与不同分布模式下的N个重复传输时机之间的对应关系。
例如，RNTI 1可以对应分布模式1下的N个重复传输时机，RNTI 2可以对应分布模式2下的N个重复传输时机，RNTI 3可以对应分布模式3下的N个重复传输时机，终端设备在接收到用RNTI 1加扰的控制信息，即可确定该RNTI 1对应分布模式下的N个重复传输时机。SS、CORESET与RNTI类似，此处不再赘述。
又例如，RNTI 1与SS 1可以对应分布模式1下的N个重复传输时机，RNTI 2与CORESET 1可以对应分布模式2下的N个重复传输时机，SS 1与CORESET 2可以对应分布模式3下的N个重复传输时机，RNTI 1、SS 1和CORESET 1可以对应分布模式4下的N个重复传输时机等等。
应理解，可以预配置或预定义由RNTI、SS和CORESET中的一个或多个组成的多种不同组合指示不同分别模式下的N个重复传输时机，此处不再一一列举。采用多个参数指示N个重复传输时机，能够扩展隐式指示的候选项数量，即不同分布模式的N个重复传输时机的数量，以便网络设备更灵活地为终端设备配置该N个重复传输时机，使本实施例适用于更多场景。
作为一个可选的实施例，所述方法还包括：所述网络设备发送导频，则对应地，所述终端设备接收导频，所述导频的序列与上述N个重复传输时机存在对应关系。
上述导频的序列既可以是参考信号的序列，也可以是同步信号对应的序列，上述导频可以例如是解调参考信号(demodulation reference signal，DMRS)、探测参考信号(sounding reference signal，SRS)、物理随机接入信道(physical random access channel，PRACH)上承载的信号、相位跟踪参考信号(phase-tracking reference signals，PTRS)，或者信道状态信息参考信号(channel state information-reference signal，CSI-RS)等等，本申请实施例对此不作限定。与上述RNTI类似，不同的导频的序列也可以对应不同分布情况的N个重复传输时机。在一种可能的实现方式中，上述导频可以是节能信号，也可以由节能信道承载。
应理解，上述通过隐式方式确定N个重复传输时机，可以节省终端设备的信令开销，以及传输资源，并且，此方法能够提高终端设备的处理灵活性；通过显式方式确定N个重复传输时机，可以节省终端设备的处理时延，可以提高终端设备的处理速度，提高数据传输效率。
作为一个可选的实施例，所述终端设备在所述K个重复传输时机中的N个重复传输时机上重复传输第一数据，包括：所述终端设备在第一时间段内，在所述N个重复传输时机上重复传输所述第一数据。所述网络设备在所述K个重复传输时机中的N个重复传输时机上重复传输第一数据，包括：所述网络设备在第一时间段内，在所述N个重复传输时机上重复传输所述第一数据。
即上述网络设备和终端设备在第一时间段内，采用本申请实施例的方法，在N个重复传输时机上重复传输第一数据。换句话说，在N个重复传输时机上重复传输数据的有效时长是第一时间段，超过了第一时间段，终端设备和网络设备可以恢复在K个重复传输时机上进行数据传输，也可以按照其他数量的重复传输次数进行数据传输，本申请实施例对此不作限定。
示例性地，终端设备和网络设备可以在开始在上述N个重复传输时机传输时开启定时器，该定时器的预设时长为上述第一时间段。在定时器超时之前在N个重复传输时机上传输第一数据，在定时器超时(即超过第一时间段)之后，便恢复在K个重复传输时机上的传输。
上述第一时间段可以是预定义的，也可以是网络设备通过信令为终端设备配置的。
作为一个可选的实施例，可以预先配置或预定义第一门限值M，M为大于1的整数，所述终端设备在所述K个重复传输时机中的N个重复传输时机上重复传输第一数据，包括：所述终端设备在累计传输次数小于或等于所述第一门限值M的情况下，在所述N个重复传输时机上重复传输所述第一数据。则对应地，所述网络设备在所述K个重复传输时机中的N个重复传输时机上重复传输第一数据，包括：所述网络设备在累计传输次数小于 或等于所述第一门限值M的情况下，在所述N个重复传输时机上重复传输所述第一数据。
应理解，一个传输周期内的数据传输次数为N，自采用N个重复传输时机传输第一数据起，P个传输周期的累计传输次数为P×N，P为大于或等于1的整数。即上述网络设备和终端设备在P×N小于或等于M的情况下，在N个重复传输时机上重复传输第一数据。假设P×N小于M，(P+1)×N大于M，终端设备和网络设备可以自第P+1个传输周期起恢复在K个重复传输时机上的传输，也可以按照其他数量的重复传输次数进行数据传输，本申请实施例对此不作限定。
作为一个可选的实施例，可以预先配置或预定义第二门限值Q，Q为大于1的整数，所述终端设备在所述K个重复传输时机中的N个重复传输时机上重复传输第一数据，包括：所述终端设备在累计传输周期小于或等于所述第二门限值Q的情况下，在所述N个重复传输时机上重复传输所述第一数据。则对应地，所述网络设备在所述K个重复传输时机中的N个重复传输时机上重复传输第一数据，包括：所述网络设备在累计传输周期小于或等于所述第二门限值Q的情况下，在所述N个重复传输时机上重复传输所述第一数据。
应理解，一个传输周期内的数据传输次数为N，累计传输周期指的是自采用N个重复传输时机传输第一数据起，累计的传输周期的个数。即上述网络设备和终端设备在累计传输周期小于或等于Q的情况下，在N个重复传输时机上重复传输第一数据。一旦累计传输周期大于Q，终端设备进而网络设备可以恢复在K个重复传输时机上的传输，也可以按照其他数量的重复传输次数进行数据传输，本申请实施例对此不作限定。
在本申请实施例中，通过上述预先配置或预先定义时间段或门限值的方式，能够更加灵活地根据实际情况对数据的重复传输次数进行调整，提高数据传输效率。
