为便于理解本申请实施例，下面先对本申请涉及到的几个概念进行简单介绍。
时域资源(或者时间单元)和时域符号：
基站和终端设备用于无线通信的时域资源可以划分为多个时域资源。并且，在本申请实施例中，多个时域资源可以是连续的，也可以是某些相邻的时域资源之间设有预设的间隔，本申请实施例并未特别限定。

在本申请的实施例中，符号也称为时域符号，可以是正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，也可以是单载波频分多址(single carrier frequency division multiple access，SC-FDMA)符号，其中SC-FDMA又称为带有转换预编码的正交频分复用(orthogonal frequency division multiplexing with transform precoding，OFDM with TP)。
在本申请实施例中，多个时域资源在时域上存在时序关系，且任意两个时域资源对应的时间长度可以相同也可以不同。
5G系统与4G通信系统相比的一大特征就是增加了对URLLC业务的支持。URLLC的业务种类包括很多种，典型的用例包括工业控制、工业生产流程自动化、人机交互和远程医疗等。为更好的量化URLLC业务的性能指标，从而给5G系统设计提供基准输入和评估准则，目前对URLLC业务的性能指标做了如下定义：
时延：时延的定义为用户应用层数据包从发送端无线协议栈2或3层的服务数据单元(service data unit，SDU)到达接收端无线协议栈2或3层的SDU所需的传输时间。URLLC业务的用户面时延要求对于上下行均为0.5ms。这里的0.5ms的性能要求仅适用于发送端(如基站)和接收端(如终端)都不处于非连续接收态(discontinuous reception,DRX)。 另外，这里0.5ms的性能要求是指数据包的平均时延，不与下述的可靠性要求绑定。
可靠性：发送端在一定时间内(L秒)向接收端正确传输X比特数据的成功概率，上述的时间(L秒)仍定义为用户应用层数据包从发送端无线协议栈2或3层的SDU到达接收端无线协议栈2或3层的SDU所需的传输时间。对于URLLC业务，一个典型需求是在1ms内发送32字节(bytes)数据达到99.999％的可靠性。需要指出的上述性能指标仅是个典型值，具体URLLC业务可能对可靠性有不同的需求，比如某些极端苛刻的工业控制需要在端到端时延在0.25ms内达到99.9999999％的传输成功概率。
现有技术中，终端设备确定向网络设备发送数据的时域资源(即上行传输)或者确定接收网络设备发送的数据的时域资源(即下行传输)的过程主要包括：
终端设备首先确定一个时域资源表格，该时域资源表格可以包括一个S参数、一个L参数，S是表示数据信道的开始(start)符号(开始符号的编号)。L(length)是表示数据信道所占的符号个数。然后终端设备接收网络设备发送的指示信息，该指示信息用于指示该时域资源表格的某一行，或者，该指示信息还可以用于指示根据时域资源表格中的S和L联合编码得到的一个开始和长度指示值(start and length indicator value，SLIV)，时域资源表格中可以包括该SLIV。终端设备根据网络设备指示的时域资源表格的某一行或者SLIV，可以确定出时域资源，
下面将具体描述终端设备确定向网络设备发送数据的时域资源或者确定接收网络设备发送的数据的时域资源的过程。
首先终端设备确定一个时域资源表格，该时域资源表格可以为协议规定的时域资源表格或者为高层信令配置的一个时域资源表格。
对于协议规定的时域资源表格，该时域资源表格包括16行，对于上行传输，每一行包括：
一个S参数、一个L参数，K2参数或者K0参数、物理下行共享信道(physical downlink shared channel,PDSCH)映射类型(mapping type)或者物理上行共享信道(physical uplink shared channel,PUSCH)映射类型(mapping type)。
其中，S是表示数据信道的开始(start)符号的编号，S是以slot的边界为参考的。L(length)是表示数据信道所占的符号个数，也可以称为数据信道的持续的符号个数，或者也可以称为数据信道的时域长度。L是从S开始的连续的符号的个数。该时域资源表格中，S和L确定出的时域资源一定是在一个slot中，某一个时域资源不会跨slot的边界。
K2参数只存在于上行传输的时域资源表格中，K0参数只存在于下行传输的时域资源表格中，也就是协议针对上行传输和下行传输分别都规定了时域资源表格。K2是指示从物理下行控制信道(physical downlink control channel,PDCCH)接收到物理上行共享信道(physical uplink shared channel,PUSCH)发送间隔的slot个数，K0是指从PDCCH接收到(physical downlink shared channel,PDSCH)接收间隔的slot个数。
对于PDSCH映射类型，PDSCH映射类型主要是确定PDSCH的解调参考信号(demodulation reference signal，DMRS)的时域符号位置，还可以用来确定PDSCH所有合理的开始位置、持续时间等。PDSCH映射包括两种类型：类型A(type A)或者类型B(type B)。type A表示第一个DMRS的位置在slot的第3或者第4个符号，type B表示第一个DMRS的位置在数据开始的第一个符号。
对于PUSCH映射类型，PUSCH映射类型主要是确定PUSCH的解调参考信号(demodulation reference signal，DMRS)的时域符号位置，还可以用来确定PUSCH所有合理的开始位置、持续时间等。PUSCH映射包括两种类型：类型A(type A)或者类型B(type B)。type A表示第一个DMRS的位置在slot的第3个符号或者第4个符号，type B表示第一个DMRS的位置在数据开始的第一个符号。
对于高层信令配置的时域资源表格，该时域资源表格最多有16行，每一行都包括下面的参数：
一个SLIV、K2参数或者K0参数、物PDSCH映射类型(mapping type)或者PUSCH映射类型(mapping type)。
其中，SLIV值是将S和L联合编码得到的结果。其中，SLIV与S和L满足以下映射关系：
如果(L-1)≤7,则SLIV＝14*(L-1)+S，
否则，SLIV＝14*(14-L+1)+(14-1-S)，其中，0＜L≤(14-S)。
在本申请中，上述映射关系被称为映射关系(1)。其中，S的取值范围为0到13，再结合上面的映射关系(1)可以看出S和L确定出来的时域资源不会跨slot的边界。通过上述映射关系(1)，一个SLIV值可以唯一的确定S的取值和L的取值的一个组合，S的取值和L的取值的一个组合也可以唯一确定一个SLIV值。
K2参数、K0参数、PDSCH mapping类型和PUSCH mapping类型的定义与协议规定的时域资源表格的定义类似，这里不再描述。
表1和表2针对不同的映射类型，对S和L的取值的组合做了进一步的限定。其中，表1为下行传输的时域资源中有效的S和L的组合表，表2为上行传输的时域资源中有效的S和L的组合表。

以表2为例说明：对于PUSCH映射类型、正常循环前缀的情况下，开始符号S只能是等于0，长度L可以是4到14的任意值，但是要满足S+L不能超过14。因为一旦超过，由于一个slot的长度为14个符号，如果S+L的值超过14，则意味着该时域资源横跨时隙边界，也就是超出一个slot的边界，跨到下一个slot中去了。由于某一个时隙的开始位置一般放置的是控制信道，不是用于承载数据的，如果某一个时域资源跨到下一个slot 中去，会影响网络设备的调度以及数据的传输，因此，S+L不能超过14，且S的值小于或者等于13。
在终端设备确定了某一个时域资源表格后，例如采用了协议规定的时域资源表格后，然后接收网络设备发送的PDCCH，该PDCCH中携带控制信息下行控制信息(downlink control information，DCI),DCI中包含一个长度为X个比特(bit)的字段，该字段用于指示时域资源表格中的某一行，从而指示出数据信道的开始符号S和长度L。终端设备也可以接收网络设备发送的高层信令，该高层信令指示该时域资源表格中的某一行，即指示数据信道的开始符号S和长度L。
又例如，在终端设备收到了高层配置的时域资源表格后，也会接收到网络设备发送的PDCCH或者是网络设备发送的高层信令，该PDCCH或者高层信令用于指示高层配置的时域资源表格中的一行，由于根据前面的描述，该时域资源表格的每一行都包含一个SLIV的值，SLIV可以根据上述的映射关系(1)确定。其中，S和L的值应满足上述的表1和表2的条件。终端设备根据SLIV值，确定出S和L，然后根据S和L，便可以确定出时域资源的位置。
根据上面的方法，终端设备便可以确定出数据信道的时域资源的开始符号和符号个数。然后在该时域资源上向网络设备发送数据或者接收网络设备发送的数据。网络设备确定数据信道的时域资源的开始符号和符号个数的方法与和上述的方法类似，
此外，网络设备还可以给终端设备发送高层信令，该高层信令用于配置一个聚合因子(aggregation factor)，该聚合因子记为K,K代表在几个连续的slot中进行数据传输。例如，终端设备确定数据信道的开始符号是在符号2，长度是是4，并且聚合因子是2，意味着在连续的2个slot中传输数据，每个slot中的数据的开始符号都是2，长度都是4。网络设备还会通过高层信令或者通过DCI指示给终端设备每个slot的格式，slot的格式是指slot中那些符号是上行符号，哪些符号是下行符号，哪些符号是灵活符号。
以上行数据传输为例：如果终端设备确定出2个连续的slot中有数据传输，且每个slot中数据传输的开始符号都是2，长度都是4，根据高层信令或者通过DCI确定出每个slot的格式，如果某一个slot中的时域资源位置与下行符号冲突，则该时域资源位置的数据传输取消，或者将传输往后延迟到上行符号位置继续进行数据传输。
现有技术中，由于数据重复传输的资源只能是slot级的，也就是每个slot只能有一个数据发送，连续K个slot重复传输，也就是只能以slot为单位进行重复传输，不允许在一个slot里面重复多次，这种设计无法满足URLLC这种低时延业务的需求。
目前提出了支持以微时隙(mini-slot)为单位的重复，mini-slot就是比一个slot的时长要短。例如，一个mini-slot的时长可以为2个符号或者4个符号，或者7个符号。mini-slot级重复可以理解为：任意两个连续的mini-slot的时域资源的开始符号的间隔小于14个符号，或者说结束符号的间隔小于14个符号。相比数据传输只能以slot级别的重复而言，mini-slot级的数据传输的时延更短，能够在保证多次重复提高可靠性的前提下，进一步的降低时延。
例如，一个传输数据的时域资源开始符号是2，长度是4个符号，如果支持mini-slot级的传输，假设重复次数为2，该数据可以在符号2至5、符号6至9传输两次，即该数据可以在一个slot中重复传输两次。如果不支持mini-slot级的传输，则需要等到下一个slot 的符号2至5再进行重复传输。
但是目前还没有确定基于多个mini-slot上重复发送数据时，多个mini-slot的资源确定的方法，并且，多个mini-slot的横跨时隙边界的问题还没有解决方案。
基于上述问题，本申请提供了一种数据传输方法和通信装置，可以支持数据在mini-slot级别的重复传输，解决了多个mini-slot的横跨时隙边界时的数据传输问题，进一步的降低数据传输的时延并提高数据传输的可靠性。
下面结合图2详细说明本申请提供的反馈信息的传输方法，图2是本申请一个实施例的反馈信息的传输方法200的示意性交互图，该方法200可以应用在图1所示的场景中，当然也可以应用在其他通信场景中，本申请实施例在此不作限制。
本申请提供的数据的传输方法，首先根据第一时域资源确定M个mini-slot级别的、不跨时隙边界的第二时域资源，然后在该M个第二时域资源上进行mini-slot级别的数据重复传输。该方法在提高数据传输的可靠性的前提下，进一步降低了数据传输的时延。
应理解，在本申请实施例中，以终端设备和网络设备作为执行方法200中的各个步骤的执行主体为例，对方法200进行说明。作为示例而非限定，执行方法200中的各个步骤执行主体也可以是应用于终端设备的芯片和应用于网络设备的芯片。
如图2所示，该方法200包括：
S210，终端设备和网络设备确定第一时域资源。
S220，终端设备和网络设备根据该第一时域资源，确定M个第二时域资源，M为大于1的整数。
S230，对于上行数据传输，终端设备在该M个第二时域资源上向网络设备发送M次第一数据，相应的，网络设备在该M个第二时域资源上接收来自于该终端设备的第一数据的M次传输。或者，对于下行数据传输，网络设备在该M个第二时域资源上向终端设备发送M次第二数据，相应的，终端设备在该M个第二时域资源上接收来自于该网络设备的第二数据的M次传输。
具体而言，在终端设备需要向网络设备发送数据或者网络设备需要向终端设备发送数据时，终端设备或者网络设备需要确定发送该数据的时域资源。例如，该数据可以是URLLC业务的数据或者可以是其他业务类型的数据。即在S210中，终端设备或者网络设备确定发送该数据的第一时域资源。
第一时域资源是终端设备向网络设备发送数据或者控制信息时使用的时域资源，第一时域资源具有确定的时域边界。第一时域资源的所占的时间长度可以是固定的，即第一时域资源可是一块时域资源。终端设备可以在该第一时域资源包括的所有符号上或者部分符号上向网络设备发送数据或者控制信息等。
第一时域资源的时域长度可以大于一个时隙，也可以小于一个时隙。并且，第一时域资源可以横跨时隙边界，也可以不横跨时隙边界。第一时域资源可以为一个时间单元，第一时域资源包括的时隙或者符号可以全部是用于上行传输的，也可以全部是用于下行传输的，或者，可以是同时包括用于上行传输和用于下行传输的符号。例如，第一时域资源包括符号4至符号10。符号4至符号10可以是全部是用于上行传输的符号，也可以全部是用于下行传输的符号，或者，符号4至符号6是用于上行传输的符号，符号7至符号10是用于下行传输的符号。本申请实施例在此不作限制。
在S220中，终端设备或者网络设备根据该第一时域资源，确定M个第二时域资源，M为大于1的整数。例如，对于URLLC业务的数据，需要保证数据传输的可靠性和降低数据传输的时延，因此，在确定了第一时域资源后，终端设备或者网络设备会根据该第一时域资源，确定M个第二时域资源。M为大于1的整数。
应理解，M个第二时域资源中，任何一个或者多个第二时域资源的长度可以小于一个时隙，例如，M个第二时域资源可以均为mini-slot级别的长度。M个第二时域资源中，每一个第二时域资源都是不横跨时隙边界。M个第二时域资源可以是连续的，即相邻两个第二时域资源之间没有时间间隔，或者相邻两个第二时域资源的时间间隔为0。当然，M个第二时域资源也可以是不连续的，例如，间隔两个符号。M个第二时域资源可以是用于上行数据传输的时域资源，或者也可以是用于下行数据传输的时域资源。
在S230中，在确定了M个第二时域资源后，如果该M个第二时域资源是用于上行数据传输的时域资源，终端设备在该M个第二时域资源上向网络设备发送M次第一数据，即每一个第二时域资源都用于传输一次第一数据，实现了第一数据的M次重复传输。也就是说M个第二时域资源用于重复发送同一个数据包或者传输块。相应的，网络设备在该M个第二时域资源上接收来自于该终端设备的第一数据的M次传输。如果该M个第二时域资源是用于下行数据传输的时域资源，网络设备在该M个第二时域资源上向终端设备发送M次第二数据，相应的，终端设备在该M个第二时域资源上接收来自于该网络设备的第二数据M次传输。
本申请提供的数据传输的方法，由于数据在该M个第二时域资源上重复传输，而M个第二时域资源是根据第一时域资源确定的，M个第二时域资源可以为mini-slot级别的长度。实现了数据的重复发送，降低了数据传输的时延，也提高了数据传输的可靠性。
可选的，作为一个实施例，图3是本申请另一个实施例的数据传输的方法的示意性交互图。如图3所示，在步骤S220中，终端设备和网络设备根据所述第一时域资源，确定M个第二时域资源，包括：
S221，终端设备或者网络设备根据该第一时域资源，确定R个第三时域资源，R为大于1的整数；
S222，终端设备或者网络设备根据R个第三时域资源是否横跨时隙边界，确定该M个第二时域资源。
具体的，由于第一时域资源的长度可以大于一个时隙，也可以小于一个时隙。由上文可知，如果某一个用于传输数据的时域资源跨到下一个slot中，会影响网络设备的调度以及数据的传输。因此，需要保证M个第二时域资源均不能横跨时隙边界，即每一个第二时域资源从开始位置到结束位置之间不能包括时隙边界。例如，假设一个slot包括14个符号，编号为0至13，某一个第二时域资源为符号8至符号13，则这个第二时域资源没有横跨时隙边界。某一个第二时域资源为符号12至符号2，即延伸到了下一个时隙的符号0、符号1、符号2，则这个第二时域资源横跨时隙边界。由于第一时域资源可以横跨时隙边界，也可以不横跨时隙边界。因此，在步骤S221中，终端设备或者网络设备根据该第一时域资源，首先确定R个第三时域资源，R为大于1的整数。在本申请中，如果没有特殊说明，均假设一个时隙有14个符号，编号分别为0至13。
应理解，R个第三时域资源中，任意一个第三时域资源的长度可以大于一个时隙，也 可以小于一个时隙。即任意一个第三时域资源可以横跨时隙边界，也可以不横跨时隙边界。R个第三时域资源可以为mini-slot级别的长度。R个第三时域资源可以是连续的，即相邻两个第三时域资源之间没有时间间隔，或者时间间隔为0。当然，R个第三时域资源也可以是不连续的，例如，间隔两个符号。R个第三时域资源可以全部是用于上行数据传输的时域资源，或者也可以全部是用于下行数据传输的时域资源。对于每个第三时域资源而言，包括的符号全部为用于上行数据传输的符号，或者，包括的符号全部为用于下行数据传输的符号。即一个第三时域资源包括的所有符号的传输方向相同。并且，R个第三时域资源中，相邻两个时域资源均用于传输相同方向的数据。例如，用于传输上行方向的数据或者用于传输下行方向的数据，即R个第三时域资源是用于上行数据传输的时域资源，或者，R个第三时域资源是用于下行数据传输的时域资源。
在步骤S222中，在确定了确定R个第三时域资源后，终端设备或者网络设备根据R个第三时域资源是否横跨时隙边界，确定M个第二时域资源。由于需要保证M个第二时域资源均不能横跨时隙边界，因此根据R个第三时域资源是否横跨时隙边界，确定M个第二时域资源，可以保证M个第二时域资源均不横跨时隙边界，从而在降低数据传输的时延的前提下，进一步保证了数据在该M个第二时域资源上传输的可靠性，提高了数据传输的效率。
可选的，作为一个实施例，图4是本申请另一个实施例的数据传输的方法的示意性交互图。如图4所示，在步骤S222中，终端设备或者网络设备根据R个第三时域资源是否横跨时隙边界，确定所述M个第二时域资源，包括：
S222a:在该R个第三时域资源都不横跨时隙边界的情况下，将该R个第三时域资源确定为该M第二个时域资源，M等于R。
具体的，由于需要保证M个第二时域资源均不横跨时隙边界，而M个第二时域资源是根据R个第三时域资源确定的。因此，如果该R个第三时域资源都不横跨时隙边界，即R个第三时域资源均满足要求，在这种情况下，可以直接将该R个第三时域资源确定为该M第二个时域资源。即R和M的值相等。R个第三时域资源就是M第二个时域资源。
举例说明：图5是本申请一个实施例的第三时域资源的示意图。图5中，R值为4，即有4个第三时域资源，第一个第三时域资源为符号10至符号11，第二个第三时域资源为符号12至符号13，第三个第三时域资源为下一个时隙的符号0至符号1，第四个第三时域资源为符号2至符号3。可以看出，这4个第三时域资源均没有横跨时隙边界，在这种情况下，将该4个第三时域资源确定为该4第二个时域资源，即M值为4，第一个第二时域资源为符号10至符号11，第二个第二时域资源为符号12至符号13，第三个第二时域资源为下一个时隙的符号0至符号1，第四个第二时域资源为符号2至符号3。
可选的，作为一个实施例，图6是本申请另一个实施例的数据传输的方法的示意性交互图。如图6所示，在步骤S222中，终端设备或者网络设备根据R个第三时域资源是否横跨时隙边界，确定该M个第二时域资源，包括：
S222b:终端设备或者网络设备将该R个第三时域资源中的横跨时隙边界的时域资源按照时隙边界进行划分。
S222c:终端设备或者网络设备根据该R个第三时域资源中不跨时隙边界的时域资源 和按照时隙边界进行划分后的时域资源，确定该M个第二时域资源。
具体而言，由于需要保证M个第二时域资源均不横跨时隙边界，而M个第二时域资源是根据R个第三时域资源确定的。因此，在步骤S222b中，如果该R个第三时域资源中存在横跨时隙边界的第三时域资源，则还需要将该R个第三时域资源中的横跨时隙边界的时域资源按照时隙边界进行划分，以确保划分后的时域资源不横跨时隙边界。在步骤S222c中，终端设备或者网络设备根据该R个第三时域资源中不跨时隙边界的时域资源和按照时隙边界进行划分后的时域资源，确定该M个第二时域资源。
举例说明：图7是本申请一个实施例的第三时域资源的示意图。图7中，R值为3，即有3个第三时域资源，第一个第三时域资源为符号8至符号11，第二个第三时域资源为符号12至下一个时隙的符号1，第三个第三时域资源为下一个时隙的符号2至符号5，可以看出，第二个第三时域资源为横跨时隙边界，在这种情况下，需要将该第二个第三时域资源按照时隙边界进行划分。然后根据划分后得到的时域资源和没有进行划分的时域资源，确定该M个第二时域资源。
作为一种具体的实现方式，将R个第三时域资源中横跨时隙边界的第四时域资源划分为H+1个第二时域资源，其中，第四时域资源是R个第三时域资源中横跨时隙边界的任意一个时域资源。第四时域资源横跨H个时隙边界，H为正整数。即如果R个第三时域资源中，某一个第三时域资源是跨H个slot边界的，则将该第三时域资源用slot边界划分为H+1个第二时域资源，每个第二时域资源上均传输同一个数据包或者传输块。M个第二时域资源包括所述H+1个第二时域资源，还包括R个第三时域资源中不跨边界的第三时域资源。
举例说明：图8是本申请一个实施例的第二时域资源的示意图。图8中所示的第二时域资源可以由图7所示的3个第三时域资源划分得到。由于图7中的第二个第三时域资源为符号12至下一个时隙的符号1。即第二个第三时域资源为该第四时域资源，第二个第三时域资源只横跨一个时隙边界，即H＝1,在这种情况下，需要将该第二个第三时域资源按照时隙边界进行划分，将第二个第三时域资源划分为两个时域资源，分别为符号12至符号13，下一个时隙的符号0至符号1。这样可以一共得到4个第二时域资源。如图8所示，每个第二时域资源均不跨时域边界。4个第二时域资源的起止符号分别为：符号8至符号11，符号12至符号13、下一个时隙的符号0至符号1，下一个时隙的符号2至符号5。
作为另一种具体的实现方式，将该R个第三时域资源中横跨时隙边界的第四时域资源划分为H+1个第五时域资源，其中，第四时域资源是R个第三时域资源中横跨时隙边界的任意一个时域资源，该第四时域资源横跨H个时隙边界，H为正整数；将该H+1个第五时域资源中的第一个第五时域资源与该第四时域资源的前一个第三时域资源合并，共同构成一个第二时域资源。将该H+1个时域资源中的最后一个第五时域资源与该第四时域资源的后一个第三时域资源合并，共同组成一个第二时域资源。即如果R个第三时域资源中，某一个第三时域资源是跨H个slot边界的，该第三时域资源为横跨时隙边界的第四时域资源。在这种划分方式中，R小于M。
应理解，上述的H+1个第五时域资源中除去第一个和最后一个第五时域资源，中间的H-1个第五时域资源可以作为H-1个第二时域资源。
还应理解，当第四时域资源为第一个第三时域资源时，则上述的第一个第五时域资源直接当做第一个第二时域资源；类似的，当第四时域资源为最后一个第三时域资源时，则最后一个第五时域资源直接当做最后一个第二时域资源。
还应理解，最终确定的M个第二时域资源中包括所述合并后的重组的第二时域资源，还包括R个第三时域资源中不跨边界的第三时域资源，以及前面所述的H-1个第二时频资源。
举例说明：图9是本申请一个实施例的第二时域资源的示意图。图9中所示的第二时域资源可以由图7所示的3个第三时域资源划分得到。由于图7中的第二个第三时域资源为符号12至下一个时隙的符号1。即第二个第三时域资源为该第四时域资源，第二个第三时域资源只横跨一个时隙边界，即H＝1,在这种情况下，需要将该第二个第三时域资源按照时隙边界进行划分为两个第五时域资源，第一个第五时域资源为符号12至符号13，第二个第五时域资源为下一个时隙的符号0至符号1。将第一个第五时域资源并入到第四时域资源的前一个第三时域资源中，即将第一个第五时域资源并入到第一个第三时域资源中，并入后第一个第二时域资源变为符号8至符号13。将第二个第五时域资源并入到第四时域资源的后一个第三时域资源中，即将第一个第五时域资源并入到第三个第三时域资源中，并入后得到第二个第二时域资源为下一个时隙的符号0至符号5。即得到两个第二时域资源。
可选的，作为一个实施例，在步骤S222中，终端设备或者网络设备根据R个第三时域资源是否横跨时隙边界，确定所述M个第二时域资源，包括：
方式一：若R个第三时域资源中有Q个第三时域资源不跨时隙边界，则该Q个第三时域资源确定为Q个第二时域资源。
若该R个第三时域资源中有横跨时隙边界的第三时域资源，将某一个横跨时隙边界的第三时域资源称为第四时域资源。如果第四时域资源横跨H个时隙边界，则第四时域资源可以确定出H+1个第二时域资源，所述H+1个第二时域资源包括，从第四时域资源的开始符号到第一个时隙边界的时域资源为一个第二时域资源，中间的H-1个时隙为H-1个第二时域资源，从最后一个时隙边界到第四时域资源的结束的时域资源确定为一个第二时域资源。
M个第二时域资源包括Q个第二时域资源和该H+1个第二时域资源。根据方式1可知，最终R大于M。
举例说明：图7是本申请一个实施例的第三时域资源的示意图。图7中，R值为3，即有3个第三时域资源，第一个第三时域资源为符号8至符号11，第二个第三时域资源为符号12至下一个时隙的符号1，第三个第三时域资源为下一个时隙的符号2至符号5，可以看出，第二个第三时域资源为横跨时隙边界，根据方式一所述的方法，根据R个第三时域资源确定的M个第二时域资源可以如图8所示。
图8是本申请一个实施例的第二时域资源的示意图。图8中所示的第二时域资源可以由图7所示的3个第三时域资源确定得到。按照方式一所述的方法，由于图7中第一个第三时域资源和第三个第三时域资源均没有跨边界，则这两个第三时域资源确定为图8中的第一个第二时域资源和第四个第二时域资源；由于图7中的第二个第三时域资源为符号12至下一个时隙的符号1。即第二个第三时域资源为该第四时域资源，第二个第三时域资 源只横跨一个时隙边界，即H＝1,在这种情况下，可以根据该第四时域资源确定2个第二时域资源，分别为符号12至符号13，下一个时隙的符号0至符号1。这样可以一共得到4个第二时域资源。如图8所示，每个第二时域资源均不跨时域边界。4个第二时域资源的起止符号分别为：符号8至符号11，符号12至符号13、下一个时隙的符号0至符号1，下一个时隙的符号2至符号5。
方式二：若所述R个第三时域资源中有横跨时隙边界的第三时域资源，将某一个横跨时隙边界的第三时域资源称为第四时域资源。如果第四时域资源横跨H个时隙边界，则根据第四时域资源可以确定出H+1个第二时域资源，包括：从第四时域资源的前一个第三时域资源的开始符号到第一个时隙边界的时域资源为一个第二时域资源，中间的H-1个时隙为H-1个第二时域资源，从最后一个时隙边界到第四时域资源后面的一个第三时域资源的结束符号的时域资源确定为一个第二时域资源。需要说明的是，如果第四时域资源为第一个第三时域资源，则所述H+1个时域资源包括：从第四时域资源的开始符号到第一个时隙边界的时域资源为一个第二时域资源，中间的H-1个时隙为H-1个第二时域资源，从最后一个时隙边界到第四时域资源后面的一个第三时域资源的结束符号的时域资源确定为一个第二时域资源；如果第四时域资源为最后一个第三时域资源，则所述H+1个时域资源包括：从第四时域资源的前一个第三时域资源的开始符号到第一个时隙边界的时域资源为一个第二时域资源，中间的H-1个时隙为H-1个第二时域资源，从最后一个时隙边界到第四时域资源的结束符号的时域资源确定为一个第二时域资源。
第五时域资源为所述R个第三时域资源中不横跨时隙边界的任意一个时域资源，且该第五时域资源前面的一个第三时域资源和后面的一个第三时域资源均不横跨时隙边界，则所述第五时域资源为一个第二时域资源；
所述M个第二时域资源包括：第四时域资源确定的第二时域资源和根据所述第五时域资源确定的第二时域资源。
举例说明：图9是本申请一个实施例的第二时域资源的示意图。图9中所示的第二时域资源可以由图7所示的3个第三时域资源确定得到。按照方式二所述的方法，由于图7中的第二个第三时域资源为符号12至下一个时隙的符号1。即第二个第三时域资源为该第四时域资源，第二个第三时域资源只横跨一个时隙边界，即H＝1,在这种情况下，可以根据第四时域资源确定出2个第二时域资源，第四时域资源的第一部分为符号12至符号13，第二部分为下一个时隙的符号0至符号1。将第一部分并入到第四时域资源的前一个第三时域资源中，并入后第一个第二时域资源变为符号8至符号13。将第二个部分并入到第四时域资源的后一个第三时域资源中，即并入到第三个第三时域资源中，并入后得到第二个第二时域资源为下一个时隙的符号0至符号5。在3个第三时域资源中，没有第五时域资源，即没有一个第三时域资源既不跨时隙边界，前后也没有跨边界的第三时域资源，例如第一个第三时域资源虽然不跨边界，但是后面的第三时域资源跨边界，第三个第三时域资源虽然不跨边界，但是前面的第三时域资源跨边界。因此共得到2个第二时域资源。
方式三：根据该R个第三时域资源中的横跨时隙边界的第四时域资源的位置以及该第四时域资源横跨的时隙边界个数，将该第四时域资源进行划分；
根据该R个第三时域资源中不跨时隙边界的时域资源和将该第四时域资源进行划分后的时域资源，确定该M个第二时域资源，其中，R和M的值相等。
具体而言，若该R个第三时域资源中前P个第三时域资源不跨边界，则该前P个第三时域资源为该M个第二时域资源中的前P个第二时域资源。
如果该R个第三时域资源中第P+1个第三时域资源跨时隙边界，则该M个第二时域资源中第P+1个第二时域资源为该第P+1个第三时域资源的开始符号到时隙边界,此时,如果P+1＝R,则该M个第二时域资源包括该P+1个第二时域资源,如果P+1<R,则该M个第二时域资源中第P+2个第二时域资源为该时隙边界到第P+1个第三时域资源的结束符号；如果P+2＝R则所有的M个第二时域资源包括该P+2个第二时域资源。如果P+2<R,则继续判断R个第三时域资源中下一个第三时域资源即第P+2个第三时域资源是否跨边界。
如果该R个第三时域资源中第P+2个第三时域资源不跨边界，则该M个第二时域资源中第P+3个第二时域资源为该第P+2个第三时域资源；如果该R个第三时域资源中第P+2个第三时域资源跨时隙边界，则该M个第二时域资源中第P+3个第二时域资源为该第P+2个第三时域资源的开始符号到时隙边界,此时如果P+3<R,则该M个第二时域资源中第P+4个第二时域资源为该时隙边界到第P+2个第三时域资源的结束符号。如果P+4＝R则所有的M个第二时域资源包括该P+4个第二时域资源。如果P+4<R,则继续判断R个第三时域资源中下一个第三时域资源即第P+3个第三时域资源是否跨边界。如此往复，确定M个第二时域资源。
根据方式三的划分步骤可以看出，最终确定的M个第二个时域资源的个数等于所述R。
结合图10所示的例子进行说明。图10本申请一个实施例的第二时域资源的示意图。图10中所示的第二时域资源可以由图7所示的3个第三时域资源确定得到。按照方式三所述的方法，
由于图7中的第1个第三时域资源不跨时隙边界，则第1个第三时域资源就是第一个第二时域资源，即第一个第二时域资源为符号8至符号11，P＝1；第2个第三时域资源跨时隙边界，则第2个第二时域资源为符号12至符号13，根据由于P+1＝2<R,则第3个第二时域资源为下个时隙的符号0到1；由于P+2＝R,则M个第二时域资源就包括了前面确定的P+2也就是3个第二时域资源分别为：符号8至符号11，符号12至符号13、下一个时隙的符号0至符号1。
换句话说，由于图7中的第1个第三时域资源不跨时隙边界，则第1个第三时域资源就是一个第六时域资源，即第一个第六时域资源为符号8至符号11，P＝1；第2个第三时域资源跨时隙边界，根据该第二个时域资源可以确定出2个第六时域资源，分别为符号12至符号13以及下个时隙的符号0到1；第2个第三时域资源跨时隙边界，则根据该第三时域资源可以确定出一个第六时域资源，为下一个时隙的符号2到符号5。M个第二时域资源就包括了4个第六时域资源中的前3个，分别为：符号8至符号11，符号12至符号13、下一个时隙的符号0至符号1。所以M等于3，R等于3。M等于R，都等于3。
应理解，在本申请实施例中，除了利用上述的两种方式将R个第三时域资源中横跨时隙边界的时域资源进行划分，结合R个第三时域资源中不跨时隙边界的时域资源确定该M个第二时域资源之外，还有其他的实现方式，只要保证该M个第二时域资源均不横跨时隙边界即可，本申请在此不作限制可选的，作为一个实施例，图11是本申请另一个实施例的数据传输的方法的示意性交互图。如图11所示，在步骤S221中，终端设备或者网络 设备根据第一时域资源，确定R个第三时域资源，包括：
S221a，终端设备或者网络设备根据重复次数R和R个第三时域资源之间的间隔，将第一时域资源重复R次，得到R个第三时域资源。
具体而言，在确定了第一时域资源后，需要根据第一时域资源确定R个第三时域资源。一种可能的方式为：根据重复次数R和R个第三时域资源之间的间隔，将第一时域资源重复R次，得到R个第三时域资源。
可选的，重复次数R可以是协议预定义的，或者网络设备可以向终端设备发送第二指示信息，该第二指示信息用于指示该重复次数R的值。该第二指示信息还可以用于指示R个第三时域资源之间的间隔。第二指示信息可以承载在DCI中也可以承载在高层信令中。在本申请中，高层信令可以是指高层协议层发出的信令，高层协议层为物理层以上的至少一个协议层。其中，高层协议层具体可以包括以下协议层中的至少一个：媒体接入控制(medium access control，MAC)层、无线链路控制(radio link control，RLC)层、分组数据会聚协议(packet data convergence protocol，PDCP)层、无线资源控制(radio resource control，RRC)层和非接入层(non access stratum，NAS)。
例如，假设确定重复次数R＝4，第一个时域资源的位置为符号9到符号12，且确定R个第三时域资源间隔的符号个数均为0，将第一个时域资源重复4次，则会得到4个第三时域资源。4个第三时域资源的起止符号分别为：符号9到符号12，符号13到符号2，符号3到符号6，符号7到符号10。
应理解，在本申请实施例中，相邻两个第三时域资源之间的间隔可以相同，也可以不同。R个第三时域资源的间隔可以是预定义的，例如协议规定。R个第三时域资源为连续的，也就是说R个第三时域资源之间的间隔为0；或者网络设备可以向终端设备发送第七指示信息，该第七指示信息用于指示R个第三时域资源之间的间隔。该第七指示信息可以直接指示R个第三时域资源中每两个相邻第三时域资源之间的间隔，也可以通过指示一个第一时域资源的模式，来间接的指示R个第三时域资源之间的间隔。第七指示信息可以承载在DCI中也可以承载在高层信令中。可选地，该第七指示信息可以和第二指示信息承载相同的DCI或者高层信令中。具体地，有很多种实现方式，例如：
网络设备可以直接通过指示信息通知给终端设备重复次数R和R个第三时域资源的间隔。或者，网络设备也可以通知终端设备R个第三时域资源是连续的，如果确定该R个第三时域资源是连续的，则可以确定R个第三时域资源的间隔是0，即为一种隐式的指示方法。或者，还可以提前定义第一时域资源的长度和R这两个参数与R个第三时域资源的间隔对应关系。例如，可以存储一张表格，如表3所示。表3所示为相邻两个第三时域资源之间的间隔相同的情况，即确定R个第三时域资源的间隔均相同。在确定了第一时域资源的长度和重复次数R这两个参数后，就可以确定R个第三时域资源的间隔。即为一个预定的模式。

应理解，表3只是示例性的，不应该对本申请的实施例造成任何限制。例如，在本申请实施例中，R个第三时域资源之间的间隔可以部分相同，或者全部不同。或者，还可以由其他方式确定R个第三时域资源的间隔。本申请实施例在此不作限制。
可选的，作为一个实施例，图12是本申请另一个实施例的数据传输的方法的示意性交互图。如图12所示，在S221中，终端设备或者网络设备根据第一时域资源，确定R个第三时域资源，包括：
S221b:终端设备或者网络设备将第一时域资源进行划分，得到R个第三时域资源。
具体而言，在确定了第一时域资源后，需要根据第一时域资源确定R个第三时域资源。另一种可能的方式为对第一时域资源进行划分，得到R个第三时域资源，即R个第三时域资源中每一个第三时域资源的持续的符号个数均小于或等于第一时域资源持续的符号个数。作为一种具体的实现方式，在步骤S221b中，终端设备或者网络设备将第一时域资源进行划分，得到R个第三时域资源，包括：
根据重复次数R，将该第一时域资源划分为该R个第三时域资源，其中，该R个第三时域资源中有R-1个第三时域资源中每个第三时域资源持续的符号个数均为
Figure PCTCN2019116781-appb-000009
L为该第一时域资源持续的符号个数，L为正整数。
Figure PCTCN2019116781-appb-000010
表示向下取整。
本实现方式还可以表述为：终端设备或者网络设备根据重复次数R，以及第一时域资源确定该R个第三时域资源，其中，该R个第三时域资源中有R-1个第三时域资源中每个第三时域资源持续的符号个数均为
Figure PCTCN2019116781-appb-000011
有一个第三时域资源持续的符号个数为

L为该第一时域资源持续的符号个数，L为正整数。
Figure PCTCN2019116781-appb-000013
表示向下取整。
具体而言，在确定了第一时域资源后，可以根据重复次数R，将第一时域资源进行划分得到R个第三时域资源。重复次数R可以网络设备通过指示信息通知给终端设备的，该指示信息可以承载在DCI或者高层信令中，或者也可以是协议预定义的。该R个第三时域资源中，有R-1个第三时域资源中每个第三时域资源持续的符号个数均为
Figure PCTCN2019116781-appb-000014
有一个第三时域资源持续的符号个数为
Figure PCTCN2019116781-appb-000015
例如，第一时域资源为第一个时隙的符号10至第二个时隙的符号4。该第一时域资源持续的L的值为9，且确定R是等于5的，计算
Figure PCTCN2019116781-appb-000016
得到计算结果为1，那么。5个第三时域资源中，有4个第三时域资源中每个第三时域资源持续的符号个数均为1，有一个第三时域资源持续的符号个数均为5。这四个持续的符号个数均为1的可以为前4个第三时域资源，也可以为后4个第三时域资源，也可以为任意的4个第三时域资源。4个第三时域资源可以连续，也可以不连续。
如果该第一时域资源持续的符号个数L刚好可以被R整除，则R个第三时域资源中，每一个第三时域资源持续的符号个数可以都相等，为L/R。即将第一时域资源平均划分为R个第三时域资源。当然，如果该第一时域资源持续的符号个数L刚好可以被R整除，R个第三时域资源中，每个第三时域资源持续的符号个数也可以不相等。
应理解，如果第一时域资源的L个符号包含了不同方向的符号，例如，第一时域资源是上行传输的资源，但是L中包含了下行的符号或者是预留的符号(例如，预留的DMRS符号)。则计算R个第三时域资源中每个第三时域资源所占的符号个数时，应该将L用L’代替，L’为L中除去下行符号和预留的符号后剩余的符号个数。
例如：第一时域资源的开始位置为第10个符号，长度L为8，第一时域资源为第一个时隙的符号10至第二个时隙的符号3，且确定R是等于4的，但是第一时域资源中包含了4个下行符号(第一个时隙的符号12至第二个时隙的符号1)，所以应该用L’＝8-4＝4来代替原来的L。这样，每个第三时域资源所占的符号个数为1。
还应理解，R个第三时域资源包括的所有符号全部是用于上行传输的，或者，R个第三时域资源包括的所有符号全部是用于下行传输的。
例如，在上述的例子中，第一时域资源的开始位置为第10个符号，长度L为8，第一时域资源为第一个时隙的符号10至第二个时隙的符号3。但是第一时域资源中包含了4个下行符号(第一个时隙的符号12至第二个时隙的符号1)，4个第三时域资源中每个第三时域资源所占的符号个数均为1，4个第三时域资源分别为第一个时隙的符号10，符号11，第二个时隙的符号2，符号3。4个第三时域资源均用于上行传输。
作为另一种具体的实现方式，在步骤S221b中，终端设备或者网络设备将第一时域资源进行划分，得到R个第三时域资源，包括：
根据该第一时域资源的第一划分方式，将该第一时域资源划分为该R个第三时域资源，其中，该第一时域资源对应多种划分方式，该第一划分方式为该多种划分方式中的一种。
本实现方式还可以表述为：终端设备或者网络设备根据该第一时域资源的第一划分方式，确定该R个第三时域资源。
具体而言，可以预定义或者配置每种长度L的第一时域资源具有固定几种划分方式。例如，图13是本申请一个实施例的长度为8的第一时域资源划分方式的示意图。假设长度L为8的第一时域资源有的4种划分方式。划分方式1将第一时域资源划分为一个第三时域资源。划分方式2将第一时域资源划分为两个第三时域资源，前四个符号为一个第三时域资源，后四个符号为一个第三时域资源。划分方式3将第一时域资源划分为三个第三时域资源，前两个符号为一个第三时域资源，后四个符号为一个第三时域资源，剩剩余的中间两个为一个第三时域资源。划分方式4将第一时域资源划分为四个第三时域资源，每两个符号为一个第三时域资源。
应理解，某一个第一时域资源的对应的划分方式可以只与该第一时域资源持续的符号个数L相关，L确定了，则对应的多种划分方式也就确定了。则终端设备或网络设备可以根据该第一时域资源，将该第一时域资源划分为该R个第三时域资源，该第一时域资源对应多种划分方式，该第一划分方式为该多种划分方式中的一种。假设第一时域资源持续的符号个数L为8，第一划分方式为划分方式3，则可以确定将该第一时域资源划分为该3个第三时域资源。应理解，图13只是示例性的，不应该对本申请的实施例造成任何限制。例如，某一个第一时域资源的对应的划分方式还可以有更多种不同的划分方式。本申请实施例在此不作限制。
网络设备可以通过向终端设备发送第一指示信息，该第一指示信息用于指示所述第一 时域资源的第一划分方式。终端设备可以通过第一指示信息确定第一时域资源的第一划分方式。第一指示信息可以承载在DCI或者是高层信令中发送给终端设备。
利用该方式将第一时域资源进行划分得到R个第三时域资源，由于网络设备不需要将重复次数R通知给终端设备，可以降低信令的开销。
作为另一种具体的实现方式，在步骤S221b中，终端设备或者网络设备将第一时域资源进行划分，得到R个第三时域资源，包括：
根据该第一时域资源内的时隙边界，将该第一时域资源划分为该R个第三时域资源；
由于第一时域资源的长度可以大于一个时隙，在第一时域资源横跨时隙边界时，可以根据该第一时域资源内的时隙边界，将该第一时域资源划分为该R个第三时域资源。本实现方式还可以表述为：终端设备或者网络设备根据该第一时域资源以及时隙边界，确定该R个第三时域资源。
具体可以有以下几种划分方式：
划分方式1：按照slot边界前的符号个数将第一时域资源划分为R个第三时域资源。
图14是本申请一个实施例的将第一时域资源按照slot边界进行划分的示意图。第一时域资源的开始符号是符号9，长度是14个符号，第一时域资源为第一个时隙的符号9至第二个时隙的符号8。通过slot边界切分以后，slot边界前剩余5个符号，slot边界后还剩余9个符号，则可以每5个符号划分出一个第三时域资源，最后将剩余4个符号构成一个单独的第三时域资源，则可以将第一时域资源划分为3个第三时域资源，即R的值为3。第一个第三时域资源为第一个时隙的符号9至符号13，第二个第三时域资源为第二个时隙的符号0至符号4，第三个第三时域资源为第一个时隙的符号9至符号13，第二个第三时域资源为第二个时隙的符号5至符号8。
本划分方式更加一般化的描述为：如果第一时域资源跨X个时隙边界，则可以按照第一时域资源在第一个slot边界前的符号个数，将第一时域资源进行划分，得到R个第三时域资源，该第一时域资源在第一个slot边界前的符号个数为T个符号。其中，第一时域资源横跨X个时隙，第一时域资源在第一个时隙边界前的符号个数为T，R个第三时域资源中的最后一个第三时域资源的符号个数小于或者等于T。
结合图15进行说明：图15是本申请一个实施例的将第一时域资源按照slot边界进行划分的示意图。第一时域资源的开始符号是符号9，长度是28个符号，第一时域资源为第一个时隙的符号9至第三个时隙的符号8，T＝5个符号。通过slot边界切分以后，slot边界前剩余5个符号，slot边界后还剩余23个符号，则可以每5个符号划分出一个第三时域资源，最后将剩余3个符号构成一个单独的第三时域资源，则可以将第一时域资源划分为6个第三时域资源，即R的值为6。第一个第三时域资源为第一个时隙的符号9至符号13，第二个第三时域资源为第二个时隙的符号0至符号4，第三个第三时域资源为第一个时隙的符号5至符号9，第四个第三时域资源为第二个时隙的符号10至第三个时隙的符号0，第五个第三时域资源为第三个时隙的符号1至符号5，第六个第三时域资源为第三个时隙的符号6至符号8。
可选地，对于划分方式1，如果第一时域资源跨X个时隙边界，则可以根据第一时域资源首先按照X个时隙边界确定出X+1个时域资源(或者也可以称为“X+1段时域资源”)，然后将X+1段时域资源中的每一段的时域资源按照第一时域资源在第一个slot边界前的符 号个数划分，该第一时域资源在第一个slot边界前的符号个数为T个符号。如果该X+1个时域资源中某个时域资源中的剩余K个符号，K<T，则将K个符号当做一个第三时域资源，或者将该K个符号归到前一个第三时域资源中。
结合图16进行说明：图16是本申请一个实施例的将第一时域资源按照slot边界进行划分的示意图。第一时域资源的开始符号是符号9，长度是28个符号，第一时域资源为第一个时隙的符号9至第三个时隙的符号8，T＝5个符号。通过slot边界切分以后，切分为3个时域资源，即X＝2，将第一时域资源切分成3段时域资源，第一段时域资源为第一个slot边界前的5个符号，第二段时域资源为第二个slot，第三段时域资源为slot边界后还剩余的9个符号。则首先将第二段时域资源每5个符号划分出一个第三时域资源，第二段时域资源中剩余4个符号构成一个单独的第三时域资源，第三段时域资源每5个符号划分出一个第三时域资源，第三段时域资源中剩余4个符号构成一个单独的第三时域资源，则可以将第一时域资源划分为6个第三时域资源，即R的值为6。第一个第三时域资源为第一个时隙的符号9至符号13，第二个第三时域资源为第二个时隙的符号0至符号4，第三个第三时域资源为第一个时隙的符号5至符号9，第四个第三时域资源为第二个时隙的符号10至13，第五个第三时域资源为第三个时隙的符号0至符号4，第六个第三时域资源为第三个时隙的符号5至符号8。图15所示的为将第二段时域资源剩余的4个符号单独当做一个第三时域资源。可选的，还可以将第二段时域资源中剩余的4个符号并入到第三个第三时域资源中，或者并入到第五个第三时域资源中。
划分方式2：按照slot边界后的符号个数将第一时域资源划分为R个第三时域资源。
图17是本申请另一个实施例的将第一时域资源按照slot边界进行划分的示意图。第一时域资源的开始符号是符号9，长度是14个符号。第一时域资源为第一个时隙的符号9至第二个时隙的符号8。通过slot边界切分以后，slot边界前剩余5个符号，slot边界后还剩余9个符号，则可以每9个符号划分出一个第三时域资源。即将第一时域资源划分为2个第三时域资源，即R的值为2。第一个第三时域资源为第一时隙的符号9至符号13，第二个第三时域资源为第二时隙的符号0至符号8。
本划分方式更加一般化的描述为：如果第一时域资源跨X个时隙边界，则可以按照第一时域资源在最后一个slot边界后的符号个数，将第一时域资源进行划分，得到R个第三时域资源，第一时域资源在最后一个slot边界后的符号个数为Y个符号，R个第三时域资源中的最后一个第三时域资源的符号个数小于或者等于Y。
可选地，对于划分方式2，如果第一时域资源跨X个时隙边界，则可以将第一时域资源首先按照X个时隙边界划分为X+1个时域资源(或者也可以称为“X+1段时域资源”)，然后将该X+1段时域资源中的每一段的时域资源按照第一时域资源在最后一个slot边界后的符号个数划分，第一时域资源在最后一个slot边界后的符号个数为Y个符号，如果X+1个时域资源中某个时域资源中的剩余K个符号，K<Y，则将K个符号当做一个第三时域资源，或者将该K个符号归到前一个第三时域资源中。
具体的划分方式可以参照划分方式1中的图14或者图15所描述的，为了简洁，这里不在赘述。区别点在于T和Y的定义不同。
可选地，将第一时域资源进行划分，得到R个第三时域资源的过程中，还可以从第一时域资源的结尾从后往前划分。
结合图18进行说明：图18是本申请一个实施例的将第一时域资源按照slot边界进行划分的示意图。第一时域资源的开始符号是符号9，长度是28个符号，第一时域资源为第一个时隙的符号9至第三个时隙的符号8，Y的值等于9个符号。通过slot边界切分以后，将第一时域资源切分为3段时域资源，第一段时域资源为第一个slot边界前的5个符号，第二段时域资源为第二个slot，第三段时域资源为slot边界后还剩余9个符号，从第一时域资源的结尾从后往前划分时，首先将第二段时域资源每9个符号划分出一个第三时域资源，第二段时域资源中前5个符号构成一个单独的第三时域资源，则可以将第一时域资源划分为4个第三时域资源，即R的值为4。第一个第三时域资源为第一个时隙的符号9至符号13，第二个第三时域资源为第二个时隙的符号0至符号4，第三个第三时域资源为第一个时隙的符号5至符号13，第四个第三时域资源为第三个时隙的符号0至8。图18所示的为将第二段时域资源中剩余的5个符号单独当做一个第三时域资源。可选的，还可以将第二段时域资源中的剩余的5个符号并入到第一个第三时域资源中，或者并入到第三个第三时域资源中。
划分方式3：按照slot边界前的符号个数和slot边界的符号个数中符号个数的较小值第一时域资源划分为R个第三时域资源。或者，按照slot边界前的符号个数和slot边界后符号个数中符号个数的较大值将第一时域资源划分为R个第三时域资源。
结合图13或者图17所示的例子，可以看出，slot边界前的符号个数为5，slot边界后的符号个数为9，则可以按照slot边界前的符号个数将第一时域资源划分为R个第三时域资源，即将第一时域资源划分为3个第三时域资源。
本划分方式更加一般化的描述为：如果第一时域资源跨X个时隙边界，则可以按照第一时域资源在第一个slot边界前的符号个数和第一时域资源在最后一个slot边界后符号个数中符号个数较小值，即按照T和Y中的较小者，将第一时域资源进行划分，得到R个第三时域资源。
可选地，如果第一时域资源跨X个时隙边界，则可以将第一时域资源首先按照H个时隙边界划分为H+1个时域资源，然后将该H+1个时域资源的每一个的时域资源按照W个符号划分，如果某个时域资源中的剩余K个符号，K<W，则将K个符号单独当做一个第三时域资源，或者将该K个符号归到前一个第三时域资源中，或者，将该K个符号归到后一个第三时域资源中。W的值可以是预定义的，也可以是网络设备配置的，W的值也可以是T和Y中的较小者。具体的划分方式可以参照划分方式1所描述的，或者参照划分方式2所描述的，这里不再赘述。
作为另一种具体的实现方式，在步骤S221b中，终端设备或者网络设备将第一时域资源进行划分，得到R个第三时域资源，包括：
根据该第一时域资源内的时域切分位置，将该第一时域资源划分为该R个第三时域资源，该时域切分位置与该第一时域资源的起点无关。换句话说，根据第一时域资源内的时域切分位置以及第一时域资源，确定出R个第三时域资源。
具体而言，可以预定义或者配置每一个slot内固定的时域切分位置，该切分位置是固定的，与第一时域资源的长度以及起点没有关系。即无论第一时域资源位置在哪，都按照第一时域资源内的固定的时域切分位置去划分第一时域资源，从而得到该R个第三时域资源。
图19是本申请一个实施例的将第一时域资源按照时域切分位置进行划分的示意图。第一时域资源的开始符号是符号9，长度是14个符号。第一时域资源为第一个时隙的符号9至第二个时隙的符号8。每一个slot内固定时域切分位置为：第3个符号的结束时刻，第7个符号结束时刻，第11个符号的结束时刻，第13个符号的结束时刻。第一时域资源的开始符号是符号9，长度是14个符号，按照固定的时域切分位置进行切分后，如图18所示，可以将该第一时域资源切分为5个第三时域资源，即R等于5。第一个第三时域资源为第一个时隙的符号9至符号11，第二个第三时域资源为第一个时隙的符号12至符号13，第三个第三时域资源为第二个时隙的符号0至符号3，第四个第三时域资源为第二个时隙的符号4至符号7，第五个第三时域资源为第二个时隙的符号8。
应理解，在本申请实施例中，除了利用上述的几种划分方式将第一时域资源进行划分得到R个第三时域资源之外，还可以利用其他的方式，例如，随机将第一时域资源进行划分，得到R个第三时域资源等。本申请实施例在此不作限制。还应理解，在本申请实施例中，终端设备和网络设备也可以根据第一时域资源，直接确定M个第二时域资源，即不需要先根据第一时域资源，确定R个第三时域资源，再根据R个第三时域资源是否横跨时隙边界，确定M个第二时域资源。不需要执行步骤S221和S222。
具体的，终端设备或者网络设备也可以根据第一时域资源是否横跨时隙边界，将第一时域资源划分为M个第二时域资源。例如，在第一时域资源不横跨时隙边界的情况下，根据M的值，可以将第一时域资源平均划分为M个第二时域资源，或者每个第二时域资源的持续的符号个数也可以不相等，具体的划分方法和步骤S221中根据第一时域资源确定R个第三时域资源的过程类似，具体地，可以参照图11所述的将所述第一时域资源划分为R个第三时域资源的方法，将所述第一时域资源划分为M个第二时域资源；或者也可以参照图12所述的利用与第一时域资源对应的某一划分方式，将第一时域资源划分为R个第三时域资源的方法，利用与第一时域资源对应的某一划分方式，将第一时域资源划分为M个第二时域资源。为了简洁，这里不再赘述。M的值可以是网络设备通过指示信息通知给终端设备的或者协议预定义的，具体可以参照重复次数R的确定方式，不再赘述。
例如，在第一时域资源横跨时隙边界的情况下，可以利用时隙边界将第一时域资源划分为M个第二时域资源。具体的划分方法可以和图13至图17所示的将第一时域资源进行划分得到R个第三时域资源的过程类似。或者也可以参照图12所示的、利用与第一时域资源对应的某一划分方式，将第一时域资源划分为M个第二时域资源。或者，还可以利用图15所示的、根据第一时域资源内的时域切分位置，将该第一时域资源划分为M个第二时域资源等。为了简洁，这里不再赘述。
可选的，图20是本申请另一个实施例的数据传输的方法的示意性交互图。如图20所示，该方法200还包括：
S211,终端设备接收来自于网络设备的第三指示信息，该第三指示信息用于指示该第一时域资源的开始和长度指示值SLIV，其中，SLIV与S和L满足以下映射关系：
如果
Figure PCTCN2019116781-appb-000017
则SLIV＝N*(L-1)+S，
否则，SLIV＝N*(N-L+1)+(N-1-S)，其中，0＜L≤(N-S),
其中，N>14。
在本申请中，上述映射关系被称为映射关系(2)。其中，S为该第一时域资源的起 始符号的编号，S为大于等于零的整数，L为该第一时域资源持续的符号个数，L和N为正整数。N可以为协议规定或者是网络设备通过信令通知给终端设备的一个数值。可选的，N＝M*14，且M为大于或者等于2的整数，例如N＝28。在本申请中，信令可以是物理层信令也可以是高层信令，上述映射关系被称为映射关系(2)。通过上述映射关系(2)，一个SLIV值可以唯一的确定S的取值和L的取值的一个组合，S的取值和L的取值的一个组合也可以唯一确定一个SLIV值。
在另一种具体的实现方式中，SLIV与S和L满足前述映射关系(1)中所述的映射关系。
S212,终端设备根据该第三指示信息，确定第一时域资源。
具体而言，在终端设备确定第一时域资源时，可以通过接收网络设备发送的第三指示信息，该第三指示信息用于指示一个时域资源表格中的一行，该时域资源表格可以为协议预定义的或者高层配置的。
当该时域资源表格为高层信令配置的时域资源表格时，该时域资源表格每一行可以包括下述参数：
一个SLIV、K2参数或者K0参数、PUSCH或者PDSCH映射类型。有关这些参数的详细描述可以参见前面的介绍，这里不加赘述。
结合上面的映射关系(2)可以看出根据S和L确定出来的时域资源可能会跨slot的边界。
因为某一个DCI中指示的开始符号S就是指示slot内的开始符号位置，所以可以进一步限制上述映射关系(2)中的S、L以及S+L的取值范围。下面以表格的形式来举例说明S、L以及S+L的取值范围的限定。
具体限定如下表4和表5所示，其中表4为下行有效的S和L的组合表，表5为上行有效的S和L的组合表，
表4
Figure PCTCN2019116781-appb-000018
表5
Figure PCTCN2019116781-appb-000019
以表5为例说明：对于PUSCH映射类型为type A、正常循环前缀的时候，开始符号S只能是等于0，长度L可以是4到N的任意值，但是要满足S+L不能超过N。
SLIV与S和L满足的映射关系以及S、L以及S+L的取值范围的限制可以是协议定 义的。SLIV是根据上述的映射关系(2)对S和L进行联合编码确定的，并且S、L应该满足表4和表5的限制。网络设备确定第一时域资源的时域位置，具体可以根据调度算法等确定第一时域资源的位置，本申请不做限定。并且该第一时域资源的开始符号S和L必须满足表4和表5的限制。网络设备确定出出第一时域资源的S和L后，便可以根据上述的映射关系(2)，对S、L联合编码确定出SLIV，通过该第三指示信息将第一时域资源的SLIV通知给终端设备。因此，在终端设备接收到用于指示该第一时域资源的SLIV的第三指示信息后，终端设备便可以根据上述的映射关系(2)，确定出第一时域资源的时域位置。第一时域资源可以横跨时隙边界。第三指示信息可以承载在DCI或者是高层信令中发送给终端设备。
作为另外一种可能的实现方式：当终端设备用于确定第一时域资源的时域资源表格为高层信令配置的时域资源表格时，该时域资源表格的每一行都包含开始符号S和长度L。其中，开始符号S和长度L的值要满足一定的限制。即网络设备确定的第一时域资源的起始符号S和长度L的值要满足一定的限制。以限定形式为表格的形式进行说明。例如起始符号S和长度L的值要满足表格6和表格7的限制。其中表6为下行有效的S和L的组合表，表7为上行有效的S和L的组合表。
表6
Figure PCTCN2019116781-appb-000020
表7
Figure PCTCN2019116781-appb-000021
其中S的候选值为0～13，L的候选值为1～P,其中P可以为协议规定的，例如正常循环前缀的时候，P可以为14。扩展循环前缀的时候，P可以为12。结合上面表格6和7.可以看出根据S和L确定出来的时域资源可能会跨slot的边界。
终端设备根据第三指示信息指示的表格的某一行，确定出S和L，然后根据S和L，便可以确定出第一时域资源的时域位置。
或者，在终端设备确定第一时域资源时，可以通过接收网络设备发送的第三指示信息，该第三指示信息直接指示开始符号S和长度L的值，开始符号S和长度L的值要满足上述的表格6和表格7的限制，终端设备根据该第三指示信息，确定出S和L，然后根据S和L，便可以确定出第一时域资源的时域位置。第一时域资源可能会横跨时隙边界。
作为另外一种可能的实现方式：
该第三指示信息用于指示一个时域资源表格中的一行，
当该时域资源表格为高层信令配置的时域资源表格时，该时域资源表格每一行可以包括下述参数：
一个SLIV、K2参数或者K0参数、PUSCH或者PDSCH映射类型。有关这些参数的详细描述可以参见前面的介绍，这里不加赘述。
结合上面的映射关系(2)可以看出根据S和L确定出来的时域资源可能会跨slot的边界。并且令其中映射关系(2)中的N＝28.S、L以及S+L的取值范围的限定仍然满足表4和表5。
或者，时域资源表格每一行包括S和L，如前所述。
可选的，该第三指示信息还用于指示第一时域资源的开始符号S和参考长度L。其中，参考长度是第一时域资源长度计算时需要用到的参数，不是实际的第一时域资源的长度。
此外，终端设备还接收网络设备发送的第四指示信息，第四指示信息指示一个X值。X为第一时域资源横跨的时隙边界的个数。相应地，网络设备发送第四指示信息，第四指示信息承载在DCI中或者承载在高层信令中。
终端设备还接收网络设备发送的第五指示信息，该第五指示信息用于指示第一时域资源的开始符号S和参考长度L。即该第五指示信息可以用于指示一个时域资源表格中的一行，该时域资源表格为高层信令配置的时域资源表格或者协议预定义的资源表格。
应理解，第五指示信息和第三指示信息可以是同一条指示信息，或者，也可以是不同的指示信息。
终端设备根据上述的第五指示信息，确定S和L，并结合第四指示信息确定第一时域资源的开始符号为S，长度为L+(X-1)*14。
可选的，终端设备还接收网络设备发送的第六指示信息，第六指示信息用于指示所述第一时域资源横跨的时隙的个数W，W为非负整数。相应地，网络设备发送第六指示信息，第六指示信息承载在DCI中或者承载在高层信令中。
终端设备还接收网络设备发送的第五指示信息，该第五指示信息用于指示第一时域资源的开始符号S和参考长度L。即该第五指示信息可以用于指示一个时域资源表格中的一行，该时域资源表格为高层信令配置的时域资源表格或者协议预定义的资源表格。
应理解，第六指示信息和第三指示信息可以是同一条指示信息，或者，也可以是不同的指示信息。
终端设备根据上述的第六指示信息，确定S和L，并结合第四指示信息确定第一时域资源的起始符号的编号S，长度为L+W*14个符号。
例如，终端设备接收第五指示信息，确定第一时域资源位置为开始符号为S＝10，参考长度为L＝7，并且接收第四指示信息，确定X＝1，则第一时域资源为符号S＝10,长度为7。
在确定了第一时域资源后，可以结合前面所述的方法根据第一时域资源，确定M个第二时域资源，保证M个第二时域资源不会跨slot的边界，M个第二时域资源用于进行数据的M次重复传输，在保证数据传输可靠性的同时，降低了传输的时延。
应理解，终端设备或者网络设备在确定第一时域资源的过程中，还可以利用现有技术中的方法确定第一时域资源。具体的，可以有如下的几种可能的实现方式：
作为一种可能的实现方式，网络设备利用表1和表2中的S、L以及S+L的取值范围 确定出第一时域资源。确定出出第一时域资源的S和L后，然后利用映射关系(1)对S、L进行联合编码确定SLIV，通过第三指示信息将第一时域资源的SLIV通知给终端设备。在终端设备接收到用于指示该第一时域资源的SLIV的第三指示信息后，终端设备便可以根据上述的映射关系(1)，结合表1和表2中的S、L以及S+L的取值范围，确定出第一时域资源的时域位置。第一时域资源是不横跨时隙边界。该第三指示信息可以承载在DCI或者是高层信令中发送给终端设备。
作为另外一种可能的实现方式：网络设备可以利用表1和表2中的S、L确定出第一时域资源。在终端设备确定第一时域资源时，可以通过接收网络设备发送的第三指示信息，该第三指示信息用于指示一个时域资源表格中的一行，该时域资源表格的每一行都包含开始符号S和长度L。其中，起始符号S和长度L的值要满足表格1和表格2的限制。终端设备根据第三指示信息，确定出S和L，然后根据S和L，便可以确定出第一时域资源的时域位置，第一时域资源不横跨时隙边界。
作为另外一种可能的实现方式：网络设备可以利用表1和表2中的S、L确定出第一时域资源。在终端设备确定第一时域资源时，可以通过接收网络设备发送的指示信息，该指示信息直接指示开始符号S和长度L的值，开始符号S和长度L的值要满足上述的表格1和表格2的限制，终端设备根据该指示信息，确定出S和L，然后根据S和L，便可以确定出第一时域资源的时域位置。第一时域资源不横跨时隙边界。
