但是，在该现有技术中，在该终端设备重复发送上行数据的过程中，无法接收到下行控制信道中发送的信息，从而不能及时根据网络设备的反馈或者信令调整当前正在进行的数据传输行为。

此外，本发明实施例的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本发明实施例中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，压缩盘(Compact Disc，CD)、数字通用盘(Digital Versatile Disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(Erasable Programmable Read-Only Memory，EPROM)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
图1是应用于本发明实施例的数据传输的通信系统的示意图。如图1所示，该通信系统100包括网络设备102，网络设备102可包括多个天线例如，天线104、106、108、110、112和114。另外，网络设备102可附加地包括发射机链路和接收机链路，本领域普通技 术人员可以理解，它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、解调器、解复用器或天线等)。
网络设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而，可以理解，网络设备102可以与类似于终端设备116或122的任意数目的终端设备通信。终端设备116和122可以是例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、PDA和/或用于在无线通信系统100上通信的任意其它适合设备。
如图1所示，终端设备116与天线112和114通信，其中天线112和114通过前向链路118向终端设备116发送信息，并通过反向链路120从终端设备116接收信息。此外，终端设备122与天线104和106通信，其中天线104和106通过前向链路124向终端设备122发送信息，并通过反向链路126从终端设备122接收信息。
例如，在频分双工(Frequency Division Duplex，FDD)系统中，例如，前向链路118可利用与反向链路120所使用的不同频带，前向链路124可利用与反向链路126所使用的不同频带。
再例如，在时分双工(Time Division Duplex，TDD)系统和全双工(Full Duplex)系统中，前向链路118和反向链路120可使用共同频带，前向链路124和反向链路126可使用共同频带。
被设计用于通信的每个天线(或者由多个天线组成的天线组)和/或区域称为网络设备102的扇区。例如，可将天线组设计为与网络设备102覆盖区域的扇区中的终端设备通信。在网络设备102通过前向链路118和124分别与终端设备116和122进行通信的过程中，网络设备102的发射天线可利用波束成形来改善前向链路118和124的信噪比。此外，与网络设备通过单个天线向它所有的终端设备发送信号的方式相比，在网络设备102利用波束成形向相关覆盖区域中随机分散的终端设备116和122发送信号时，相邻小区中的移动设备会受到较少的干扰。
在给定时间，网络设备102、终端设备116或终端设备122可以是无线通信发送装置和/或无线通信接收装置。当发送数据时，无线通信发送装置可对数据进行编码以用于传输。
具体而言，无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中，传输块可被分段以产生多个码块。
此外，该通信系统100可以是公共陆地移动网络(Public Land Mobile Network，PLMN)网络或者D2D网络或者M2M网络或者其他网络，图1只是举例的简化示意图，网络中还可以包括其他网络设备，图1中未予以画出。
下面，对该通信系统100所使用的用于无线通信的时间单元进行详细说明。
在本发明实施例中，网络设备和终端设备用于传输数据的时域资源在时域上可以划分为多个时间单元。
并且，在本发明实施例中，多个时间单元可以是连续的，也可以是某些相邻的时间单元之间设有预设的间隔，本发明实施例并未特别限定。
在本发明实施例中，时间单元可以是包括用于上行信息(例如，上行数据)传输和/ 或下行信息(例如，下行数据)传输的时间单元。
在本发明实施例中，一个时间单元的长度可以任意设定，本发明实施例并未特别限定。
例如，1个时间单元可以包括一个或多个子帧。
或者，1个时间单元可以包括一个或多个时隙。
或者，1个时间单元可以包括一个或多个符号。
或者，1个时间单元可以包括一个或多个TTI。
或者，1个时间单元可以包括一个或多个短传输时间间隔(short Transmission Time Interval，sTTI)。
在本发明实施例中，通信系统100所使用的用于无线通信的时域资源在时域上可以划分为多个TTI，TTI是目前通信系统(例如，LTE系统)中的普遍使用的参数，是指在无线链路中调度数据传输的调度单位。在现有技术中，通常认为1TTI＝1ms。即，一个TTI为一个子帧(subframe)或者说，两个时隙(slot)的大小，它是无线资源管理(调度等)所管辖时间的基本单位。
在通信网络中，时延是一个关键的性能指标，同时也影响着用户的使用体验。随着通讯协议的发展，对时延影响最明显的物理层的调度间隔也越来越小，在最初的WCDMA中，调度间隔是10ms，高速分组接入(High-Speed Packet Access，HSPA)中调度间隔缩短到2ms，长期演进(Long Term Evolution，LTE)中调度间隔(即，TTI)缩短到1ms。
小时延的业务需求导致物理层需要引入更短的TTI帧结构，以进一步缩短调度间隔，提高用户体验。例如，LTE系统中TTI长度可以从1ms缩短为1符号(symbol)到1时隙(包括7个符号)之间。上述提及的符号可以是LTE系统中的正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号或单载波频分多址(Single Carrier-Frequency Division Multiple Access，SC-FDMA)符号，还可以是其他通信系统中的符号。又例如，5G通信系统中TTI长度也小于1ms。
LTE系统在基于长度为1ms的TTI的数据传输中，一般情况下数据传输的来回时间(Round-Trip Time，简称“RTT”)为8ms。假设，和现有长度为1ms的TTI的调度相比，处理时间是等比例缩减的，即仍然遵循现有的RTT时延。那么，当基于长度为0.5ms的sTTI的数据传输中，数据传输的RTT为4ms，相对于基于长度为1ms的TTI的数据传输，时延能够缩短一半，从而提高用户体验。
长度小于1ms的TTI可以称为sTTI。例如，LTE系统中，sTTI的长度可以为1～7个符号中任意一种长度，或者，sTTI长度也可以是1～7个符号中至少2种不同长度的组合，例如1ms内包含6个sTTI，各sTTI长度可以分别是3个符号、2个符号、2个符号、2个符号、2个符号、3个符号，或者，1ms内包含4个sTTI，各sTTI长度可以分别是3个符号、4个符号、3个符号、4个符号，各sTTI长度还可以是其他不同长度的组合。
并且，上行的sTTI长度可以和下行的sTTI长度相同，例如上行的sTTI长度和下行的sTTI长度均为2个符号。
或者，上行的sTTI长度可以长于下行的sTTI长度，例如上行的sTTI长度为7个符号，下行的sTTI长度为2个符号。
再或者，上行的sTTI长度可以短于下行的sTTI长度，例如上行的sTTI长度为4个符号，下行的sTTI长度为1个子帧。
TTI长度小于1个子帧或1ms的数据包称为短TTI数据包。短TTI数据传输在频域上，可连续分布，也可非连续分布。需要说明的是，考虑到后向兼容性，系统中可能同时存在基于长度为1ms的TTI的数据传输和基于sTTI的数据传输的情况。
在本发明实施例中，可以将现有技术(例如LTE系统)规定的(例如，长度为1ms或长度大于1ms的)TTI和sTTI统称为TTI，并且，在本发明实施例中，TTI的长度可以根据实际需要进行变更。
应理解，以上列举的时间单元的结构仅为示例性说明，本发明实施例并未特别限定，可以根据实际需要对时间单元的结构进行任意变更，例如，对于不支持sTTI的LTE系统而言，1个时间单元可以为1个子帧(Subframe)。再例如，对于支持sTTI的LTE系统而言，1个时间单元可以包括1个sTTI，或者说，1个时间单元可以包括1个时隙(Slot)，1个时间单元可以包括一个或多个(例如，小于7的正整数个或小于6的正整数个)符号；1个时间单元也可以为1个子帧。
需要说明的是，在本发明实施例中，时间单元用于传输信息的长度(或者说，信息传输时长)可以是1ms，也可以小于1ms。
本申请实施例中可以应用于LTE系统中的MTC通信中或独立于LTE系统的窄带物联网通信(Narrow Band Internet of Things,NB-IoT)中，所谓的MTC或NB-IoT，就是指通过部署具有一定感知、计算、执行和通信能力的各种设备，获取物理世界的信息，通过网络实现信息传输、协同和处理，从而实现人与物、物与物之间的互联，在智能家居、电子健康以及智能电网等领域得到的广泛应用，以下内容以MTC通信为例来说明。
其中，应用于MTC通信中的终端设备具有低功耗、对时延要求不敏感、小数据传输等特性。在MTC通信中，考虑到MTC类型的终端设备(例如水表、电表)所处的环境，使得信号覆盖强度无法满足信号接收要求，因此需要对MTC通信进行增强，使网络设备和终端设备能够支持扩展覆盖(Coverage Enhancement，CE)。一种方案中，目前实现扩展覆盖的主要方法是重复发送数据，通过多次接收合并来提高数据的接收成功率。
图2所示为MTC通信中数据传输过程的示意性框图。结合图2对本申请实施例的数据传输过程进行说明。
如图2所示，在第一次调度过程中，网络设备通过下行控制信道重复发送调度信息(为了便于区分与理解，记为调度信息#1)来调度终端设备发送上行数据，该网络设备在任意两次发送的调度信息#1都相同，以提高调度信息#1的传输可靠性；该终端设备在接收完重复发送的调度信息#1后，在调度信息#1所指示的上行数据信道上重复发送上行数据(为了便于区分与理解，记为上行数据#1)，任意两次发送的上行数据#1都相同，以提高上行数据#1的传输可靠性；当重复发送完上行数据#1后，该终端设备等待该网络设备的下一次调度，即，在第二次调度过程中，该终端设备通过下行控制信道接收重复发送的调度信息(为了便于区分与理解，记为调度信息#2)，该调度信息#2不仅可以用于指示该终端设备发送上行数据所使用的时频资源(即，上行数据信道)，也可以用于指示该终端设备发送的上行数据是初传数据或重传数据，若该调度信息#2指示的是重传数据，则表示该网络设备未成功接收该上行数据#1，则该终端设备通过上行数据信道重复发送的上行数据(为了便于区分与理解，记为上行数据#2)与该上行数据#1相同；若该调度信息#2指示的是初传数据，则表示该网络设备成功接收该上行数据#1，则该终端设备通过上行数据 信道重复发送的上行数据#2与该上行数据#1不同。
应理解，下行控制信道承载调度信息，上行数据信道承载上行数据，并且，承载重复发送的调度信息的下行控制信道在时域上是连续的时间单元，或者说，承载重复发送的调度信息的下行控制信道的时域资源是连续的时间单元；承载重复发送的上行数据的上行数据信道在时域上是连续的时间单元，或者说，承载重复发送的上行数据的上行数据信道的时域资源是连续的时间单元。此外，本文中连续的时间单元为连续的有效时间单元，即能够用于发送调度信息或上行数据的时间单元。至于上行数据信道或下行控制信道的频域资源，本申请实施例不做任何限定。
还应理解，图2中所示的终端设备一次发送的上行数据#1承载于上行数据信道中的一个时间单元上仅为示意性说明，不应对本申请实施例构成限定，例如，终端设备一次发送的上行数据#1也可以承载于上行数据信道中的至少两个时间单元上。
还应理解，换一种描述说，由于上行数据承载于上行数据信道中，所以，重复发送上行数据也可以理解为重复发送上行数据信道；同理，由于调度信息承载于下行控制信道中，重复发送调度信息也可以理解为重复发送下行控制信道。下文中关于重复发送调度信息以及重复发送上行数据的解释同此处，为了简洁，后续不再赘述。
在本申请实施例中，下行控制信道可以是物理下行控制信道(Physical Downlink Control Channel，PDCCH)，也可以是机器类型通信的物理下行控制信道(MTC Physical Downlink Control Channel，MPDCCH)，也可以是窄带物理下行控制信道(Narrowband Physical Downlink Control Channel,NPDCCH)，上行数据信道可以是物理上行共享信道(Physical Uplink Shared Channel,PUSCH)，也可以是窄带物理上行共享信道(Narrowband Uplink Shared Channel,NPUSCH)，本申请实施例不做限定。
需要说明的是，在本申请实施例中，重复发送的调度信息指的是对未经调制编码的原始信息进行重复，同理，重复发送的上行数据指的是对未经调制编码的原始数据进行重复，在空口发送的调度信息或者上行数据可能是不完全相同的，例如使用不同的冗余版本进行调度信息或者上行数据的发送。下文关于调度信息以及上行数据的解释同此处，为了简洁，后续不再赘述。
此外，本申请实施例中的上行数据为物理层概念，不区分是用户面数据还是高层信令。
下面，结合图3至图8，详细描述本申请实施例的数据传输的方法。图3所示为根据本申请实施例的数据传输的方法200的示意性交互图。
可选地，该网络设备为基站。
本申请实施例可以应用于包括网络设备和至少一个终端设备的通信系统中，以下，不失一般性，以网络设备和该至少一个终端设备中的终端设备#A(即，终端设备的一例)的交互为例，详细说明根据本申请实施例的数据传输的方法200。
在步骤S210中，该终端设备#A使用第一混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)进程，从连续的N个时间单元上的第1个时间单元开始重复发送上行数据。
即，该终端设备#A基于网络设备的调度，在连续的N个时间单元上开始重复发送上行数据(为了便于区分与理解，记为上行数据#A)，即，任意两次发送的上行数据都为上行数据#A，并且，发送该上行数据的HARQ进程为HARQ进程#1(即，该第一HARQ进 程的一例)。其中，该N个时间单元是承载连续发送的上行数据#A的上行数据信道的时域资源。
可选地，在该步骤S210之前，该方法还包括：
该网络设备向该终端设备#A发送调度信息，该调度信息用于指示该终端设备#A在连续的N个时间单元上重复发送该上行数据#A。
即，该N个时间单元是网络设备通过调度信息所指示的，并且，该N个时间单元为有效的时间单元，即可以用于发送上行数据的时间单元。这样，该终端设备#A在接收到该调度信息后，在步骤S210中，该终端设备#A基于该调度信息，从该N个时间单元中的第1个时间单元开始重复发送该上行数据#A。
在步骤S220中，在该N个时间单元中的第M个时间单元内，该终端设备#A开启第一定时器，该第一定时器对应该第一HARQ进程，该M为小于N的整数。
具体而言，该终端设备#A在发送上行数据的过程中，即，在该N个时间单元中的第M个时间单元内，开启第一定时器，监听下行控制信道，以便于接收到该网络设备发送的针对该上行数据#A的反馈信息。该终端设备#A可以在该第M个时间单元对应的时段中的任意时刻开始该第一定时器，例如，该终端设备#A可以在该第M个时间单元对应的时段中的起始时刻开启该第一定时器，也可以在该M个时间单元对应的时段中的结束时刻开启该第一定时器等，本申请实施例不做任何限定。
该第一定时器用于监听承载有针对使用该第一HARQ进程发送的上行数据(即，该上行数据#A)的反馈信息的下行控制信道，即，该第一定时器对应该第一HARQ进程。也就是说，系统配置的所有HARQ进程中，每个HARQ进程对应一个第一定时器，当该终端设备#A使用一个HARQ进程重复发送上行数据时，在重复发送上行数据的过程中开启对应的定时器，来监听下行控制信道，任意两个HARQ进程对应的定时器都是相互独立的，即，一个HARQ进程对应的定时器的开启与停止不影响另一个HARQ进程对应的定时器的开启与停止。此外，本申请实施例中的第一HARQ进程可以是所有HARQ进程中的任一个HARQ进程。
在步骤S230中，在该第一定时器的运行期间，该终端设备#A监听下行控制信道。
也就是说，该终端设备#A在开启该第一定时器后，在该第一定时器的运行期间内，监听下行控制信道，可以通过下行控制信道接收该网络设备可能发送的针对该上行数据#A的反馈信息，这样，在该终端设备#A接收到针对该上行数据#A的反馈信息后，可以停止发送该上行数据#A。
应理解，本申请实施例中的反馈信息是针对上行数据的反馈信息，也可以理解为是针对HARQ进程的反馈信息。
在现有技术中，该终端设备#A在重复发送该上行数据#A的过程中，若该网络设备成功接收到该上行数据#A，可以发送针对该上行数据#A的反馈信息，但是，由于该终端设备#A可能不监听下行控制信道，使得该终端设备不能接收到该反馈信息，从而不能及时根据该网络设备的反馈信息来调整当前正在进行的数据传输行为。其中，数据传输行为可以包括继续数据传输或停止数据传输。
因此，本申请实施例的数据传输的方法，终端设备在重复发送上行数据的过程中开启第一定时器，即，该终端设备在用于承载重复发送的上行数据的N个时间单元中的第M 个时间单元上开启该第一定时器，该第一定时器对应第一混合自动重传请求进程，该第一混合自动重传请求进程是该终端设备重复发送该上行数据的混合自动重传请求进程，可以使得该终端设备监听下行控制信道，以接收网络设备可能发送的针对该上行数据的反馈信息，以便于及时调整上行数据的传输，提高通信灵活性。
在一种可选的实施方式中，该方法还包括：
在该第一定时器的运行期间且在该N个时间单元对应的时段内，若该终端设备接收到承载于该下行控制信道的反馈信息，则该终端设备停止发送该上行数据，该反馈信息包括该网络设备针对该上行数据的正确应答ACK。
具体地，该终端设备#A在监听下行控制信道且在重复发送该上行数据#A的过程中，若接收到该网络设备发送的针对该上行数据#A的反馈信息(为了便于区分与理解，记为反馈信息#A)，且该反馈信息#A包括用于指示该网络设备成功接收该上行数据#A的正确应答(Acknowledge，ACK)，则该终端设备#A在后续的时间单元上停止发送该上行数据#A。
例如，N＝10，M＝2，该终端设备#A在第2个时间单元内开始该第一定时器，且在第4个时间单元对应的时段上接收到该反馈信息#A，则自第5个时间单元开始停止发送该上行数据#A。
因此，在该第一定时器的运行期间且在重复发送上行数据的过程中，若该终端设备接收到包括针对上行数据的正确应答ACK的反馈信息后，可以停止发送该上行数据，能够减少资源的浪费，同时，也减少了由于发送上行数据而增加的功耗。
下面，从该第一定时器的开启时间以及该第一定时器的时长两方面对本申请实施例的第一定时器做进一步说明。
该第一定时器的开启时间
如前所述，该M为小于N的整数，也就是说，该终端设备#A可以在除第N个时间单元以外的时间单元对应的时段开启该第一定时器，本申请实施例不做任何限定。
在一种可选的实现方式中，M＝1，即，该终端设备#A在该N个时间单元中的第1个时间单元对应的时段开启该第一定时器，可以尽可能地在该终端设备#A重复发送上行数据的过程中都能监听下行控制信道。
在另一种可选的实现方式中，M可以基于该网络设备对数据的处理能力而设置，其中，该网络设备对数据的处理能力主要考虑该网络设备对数据的解调译码能力。
例如，假设该网络设备从接收到该上行数据#A到将该上行数据#A解调译码成功再到发送针对该上行数据#A的反馈信息的过程中，需要三个时间单元的时长，那么，该M可以被设置为4，即，第1次发送上行数据#A的第1个时间单元加上该网络设备处理数据占用的3个时间单元的时长，这样，考虑到网络设备的处理能力而设置的该第一定时器的开启时间，可以在进一步节省功耗的情况下，尽可能地在该终端设备#A重复发送上行数据的过程中监听下行控制信道。
此外，该终端设备#A可以在第M个时间单元对应的时段的任何时刻开启该第一定时器，即，该终端设备#A可以在该第M个时间单元对应的时段的起始时刻、中间任意时刻或者结束时刻开启该第一定时器，本申请实施例并不限于此。
该第一定时器的时长
在一种可选的实现方式中，该第一定时器的时长为P个时间单元对应的时长，其中，P＝N-M+1。
换句话说，该第一定时器的时长的设置与该第一定时器的开启时间和该网络设备所指示的N个时间单元相关，即，当该第一定时器在第M个时间单元对应的时段内被开启，在第N个时间单元被停止，则该第一定时器的时长为P个时间单元对应的时段，即P＝N-M+1。
再具体实现中，该第一定时器可以是狭义上的计时器，即该第一定时器的时长可以被设置一个预设时长，该预设时长为P个时间单元对应的时段；该第一定时器的时长也可以通过计数器的形式被设置为P个时间间隔，每个时间间隔对应一个时间单元的时长，在该第一定时器的运行期间，每间隔一个时间间隔，增加一次计数，直到满足条件时停止该第一定时器的运行。
作为示例而非限定，P>N-M+1，即，该第一定时器的超时时间在该N个时间单元对应的时段之后的时间。
结合该第一定时器的开启时间以及该第一定时器的时长，在一种可选的实现方式中，若该终端设备#A在第M个时间单元对应的时段的起始时刻开启该第一定时器，P＝N-M+1则该第一定时器在P个时间单元对应的时长后停止运行。
在一种可选的实现方式中，该方法还包括：
在该第一定时器的运行期间，若该终端设备接收到承载于该下行控制信道的反馈信息，则该终端设备停止该第一定时器，该反馈信息包括该网络设备针对该上行数据的正确应答ACK。
具体而言，在该第一定时器的运行期间，若该终端设备#A接收到该反馈信息#A，那么，该终端设备#A就已经确定该网络设备成功接收该上行数据#A，也就可以不再监听下行控制信道，则可以停止该第一定时器，可以进一步节省该终端设备#A的功耗。
需要说明的是，该反馈信息#A可以是该网络设备在该第一定时器的运行期间且在该N个时间单元对应的时段内发送的反馈信息，也可以是该网络设备在该第一定时器的运行期间但是在该N个时间单元对应的时段以后发送的反馈信息，本申请实施例不做任何限定。
作为示例而非限定，若该终端设备#A在该第一定时器的运行期间且在该N个时间单元对应的时段内接收到该反馈信息#A，则终端设备#A停止发送该上行数据#A，但是，可以不停止该第一定时器的运行，即可以继续监听下行控制信道。
当然，若该第一定时器超时，该第一定时器自然停止运行，那么，该终端设备#A也可以停止监听下行控制信道。
下面，结合图4至图6详细说明本申请实施例中终端设备在不同时段内接收反馈信息的过程中的示意性行为图。其中，假设，N＝15，M＝1，该第一定时器的时长大于该N时间单元对应的时长，该第一定时器的开启时间为第1个时间单元的起始时刻。
在图4中，该网络设备调度的该终端设备#A重复发送上行数据#A的上行数据信道在时域上是连续的15个时间单元，该终端设备#A在第1个时间单元对应的时段的起始时刻开启该第一定时器，监听下行控制信道，在该第一定时器内的运行期间，当该终端设备#A在第9个时间单元上接收到该反馈信息#A时，该终端设备#A停止该第一定时器，并且， 该终端设备#A自第10个时间单元开始停止发送该上行数据#A。
在图5中，该网络设备调度的该终端设备#A重复发送上行数据#A的上行数据信道在时域上是连续的15个时间单元，该终端设备#A在第1个时间单元对应的时段的起始时刻开启该第一定时器，监听下行控制信道，在该第一定时器内的运行期间，在15个时间单元对应的时段内未接收到该反馈信息#A，但是在第15个时间对应的时段之后接收到该反馈信息#A，该终端设备#A停止该第一定时器。
在图6中，该网络设备调度的该终端设备#A重复发送上行数据#A的上行数据信道在时域上是连续的15个时间单元，该终端设备#A在第1个时间单元对应的时段的起始时刻开启该第一定时器，监听下行控制信道，在该第一定时器内的整个运行期间，该终端设备#A都未接收到该反馈信息#A，那么，在该第一定时器超时后，该第一定时器自然停止运行，该终端设备#A停止监听下行控制信道。实际上，在这种情况下，该网络设备很可能并没有成功接收该上行数据#A，会在下一次调度中重新调度该终端设备#A重复发送该上行数据#A。
图4至图6中该第一定时器的时长为P个时间单元对应的时长，其中，P>N-M+1。下面，结合图7和图8，对P＝N-M+1的情况也做一简单说明，假设，N＝15，M＝1，该第一定时器的开启时间为第1个时间单元的起始时刻，此种情况下，该第一定时器的时长为该N个时间单元对应的时长。
图7与图4的不同在于，该第一定时器的时长的停止时间是第15个时间单元(即，第N个时间单元)的结束时刻，图8与图6的不同在于，该第一定时器的停止时间是第15个时间单元的结束时刻，在图8所示的情况下，该第一定时器在第15个时间单元的结束时刻停止运行，该终端设备不再监听下行控制信道，不接收反馈信息。
需要说明的是，图4至图8所示的该终端设备#A在连续的N个时间单元上重复发送该上行数据#A的过程，可以是针对该上行数据#A的初传过程，或者说，可以是针对该网络设备的第一次调度而发送的上行数据，可以对应图2所示的第一次调度过程；同时，图4至图8所示的该终端设备#A在连续的N个时间单元上重复发送该上行数据#A的过程，也可以是针对该上行数据#A的重传过程，或者说，可以是针对该网络设备的第二次调度而发送的上行数据，可以对应图2所示的第二次调度过程。
本申请实施例中的第一定时器可以是系统新定义或新配置的定时器，例如PDCCH监听定时器(Monitor Timer)或MPDCCH Monitor Timer或HARQ-ACK Monitor Timer等，本申请对第一定时器的具体名称不做限定。所述第一定时器也可以是对现有技术中已有的定时器稍作修改后得到的定时器，对于修改现有技术中已有的定时器的情况做一简单说明。
情况1
在一种现有技术中，若该网络设备未成功接收第一次调度过程的上行数据，会再次调度该终端设备#A发送重传数据，为了使得该终端设备#A能够接收与重传相关的调度信息，引入了重传定时器(Drx-Retransmission Timer)。具体而言，当该终端设备#A在第一次调度的上行数据信道重复发送完上行数据后，开启上行往返定时器(Uplink Round Trip Time Timer,UL RTT Timer)，在UL RTT定时器运行期间，该终端设备#A可以不用监听下行数据信道，在UL RTT定时器超时后，开启重传定时器，监听下行控制信道，以便于接收 网络设备发送的调度信息。
在本申请实施例中，该第一定时器可以是修改开启时间的重传定时器，即，重用现有的重传定时器，但是改变了重传定时器的开启时间，即在该终端设备#A重复发送上行数据的过程中开启该重传定时器，直到该重传定时器超时。这里，需要说明的是，若重用现有的重传定时器，该重传定时器的时长可以设置较长，在该重传定时器的运行期间，不仅可以在该终端设备#A重复发送上行数据的过程中监听下行控制信道，以便于接收反馈信息，也可以通过监听下行控制信道来接收重传或新传的调度信息。
在一种可选的实施方式中，当该终端设备#A配置或激活了针对HARQ的反馈机制，则重传定时器的开启条件如上所述，并且，可以不需要再使用UL RTT Timer，当该终端设备#A没有配置或没有激活针对HARQ的反馈机制，则重传定时器的使用过程同现有技术。
情况2
在另一种现有技术，终端设备#A开始接入到网络设备时，需要经过随机接入过程。具体过程如下：该终端设备#A向该网络设备发送随机接入前导码(Preamble码)；随后，该网络设备向该终端设备#A发送随机接入响应(Random Access Response,RAR)消息，在这个过程中，可能会有其他终端设备也使用相同资源的发送了相同的随机接入前导码，使得该网络设备并不知道是哪个该终端设备发送的随机接入前导码，这样，包括该终端设备#A在内的多个终端设备都可以接收到该网络设备发送的RAR消息；于是，在该多个终端设备接收到该RAR消息后，该多个终端设备都分别向该网络设备发送第三条消息(Msg3)，该第三条消息中包括终端设备的系统架构演进临时移动用户标识(System Architecture Evolution Temporary Mobile Subscriber Identity,S-TMSI)，不同的终端设备的标识是不一样的，这样，该网络设备能够通过终端设备的标识来区分出每个；然后，该网络设备向终端设备发送冲突解决(Contention Resolution,CR)消息，以解决这次随机接入过程中的冲突。在CR消息中包括该网络设备接受随机接入请求的终端设备的标识，对于该终端设备#A来说，当该终端设备#A在该CR消息检测到自己的标识时，该终端设备#A可以确定该网络设备接受了该终端设备#A的随机接入请求，其他终端设备没有在该CR消息中检测到自己的标识，则认为该网络设备没有接受自己的随机接入请求，准备再进行随机接入过程；当该终端设备#A在该CR消息中未检测到自己的标识，则认为该网络设备没有接受自己的随机接入请求，准备再进行随机接入过程。
其中，在该现有技术中，该第三条消息承载于上行数据信道中，该终端设备#A在上行数据信道重复发送完该第三条消息后，会启动冲突解决定时器(mac-Contention Resolution Timer)，来监听下行控制信道，以接收该CR消息，若直到冲突解决定时器超时，该终端设备#A都没有接收到该CR消息，则该终端设备#A确定此次随机接入失败。
那么，基于该现有技术，在本申请实施例中，该第一定时器可以是修改开启时间的冲突解决定时器，即，重用现有的冲突解决定时器，但是改变了冲突解决定时器的开启时间，即在该终端设备#A重复发送该第三条消息的过程中开启该冲突解决定时器，直到该冲突解决定时器超时。这里，需要说明的是，若重用现有的冲突解决定时器，该冲突解决定时器的时长可以设置较长，在该冲突解决定时器的运行期间，不仅可以在该终端设备#A重复发送该第三条消息的过程中监听下行控制信道，以便于接收针对该第三条消息的反馈信 息，使得在接收到针对该第三条消息的反馈消息后，可以及时停止发送该第三条消息，也可以在后续监听下行控制信道的过程中，以便于接收该CR消息，确定该网络设备是否接受自己的随机接入请求。
基于上述情况，在一种可选的实施方式中，该上行数据可以包括上述情况2中随机接入过程中由随机接入响应消息调度的上行数据(为了便于区分与理解，记为上行数据#A1)，或，该上行数据可以包括除随机接入过程以外的其他场景中该终端设备#A发送的上行数据(为了便于区分与理解，记为上行数据#A2)，例如，上述情况1中的上行数据。
其中，该上行数据#A1可以包括上述情况2中所描述的第三条消息，该上行数据#A1中可以包括该终端设备#A的标识，该终端设备#A的标识可以是该终端设备#A的S-TMSI，也可以是通过随机序列生成的临时标识。
因此，本申请实施例提供的数据传输的方法，一方面，终端设备在重复发送上行数据的过程中开启第一定时器，即，该终端设备在用于承载重复发送的上行数据的N个时间单元中的第M个时间单元上开启该第一定时器，该第一定时器对应第一混合自动重传请求进程，该第一混合自动重传请求进程是该终端设备重复发送该上行数据的混合自动重传请求进程，可以使得该终端设备在重复发送上行数据的过程中监听下行控制信道，以接收网络设备可能发送的针对该上行数据的反馈信息，以便于及时调整上行数据的传输，提高通信灵活性；
另一方面，在该第一定时器的运行期间且在重复发送上行数据的过程中，若终端设备接收到包括针对上行数据的正确应答ACK的反馈信息，可以及时停止发送该上行数据，能够减少资源的浪费，同时，也减少了由于发送上行数据而增加的功耗；
再一方面，在第一定时器的运行期间，若终端设备接收到包括针对上行数据的正确应答ACK的反馈信息，可以及时停止该第一定时器，能够进一步节省该终端设备的功耗。
本申请实施例还提供了一种数据传输的方法，图9所示为根据本申请实施例的数据传输的方法300的示意性交互图。
同方法200的描述，以网络设备和终端设备#A的交互为例，详细说明根据本申请实施例的数据传输的方法300。
在步骤S310中，网络设备在连续的Q个时间单元上重复发送调度信息，该调度信息用于指示终端设备在N个时间单元上重复发送上行数据，该N和Q都为大于1的整数。
具体而言，该网络设备通过调度信息来调度该终端设备#A在连续的N个时间单元上重复发送上行数据，该调度信息承载于下行控制信道中，与方法200中上行数据的发送方式相同，为了提高该终端设备#A针对该调度信息的接收成功率，该网络设备在连续的Q个时间单元上重复发送该调度信息，即，承载该调度信息的下行控制信道在时域上是连续的Q个时间单元。
进而，在步骤S310中，该终端设备#A接收该调度信息。
在步骤S320中，在该终端设备接收到在该Q个时间单元的最后一个时间单元上发送的调度信息时，该终端设备开启第二定时器，开始监听下行控制信道。
这里，该第二定时器对应所有的HARQ进程，即，在该第二定时器的运行期间，监听承载针对使用所有HARQ进程发送的上行数据的反馈信息的下行控制信道。
在步骤S330中，在该第二定时器的运行期间，若该终端设备接收到该网络设备发送 的L个反馈信息，则该终端设备停止该第二定时器，其中，该L个反馈信息与L个混合自动重传请求进程一一对应，该L个HARQ进程是系统配置的所有混合自动重传请求进程，该L个反馈信息中的第i个反馈信息是针对第j个上行数据的反馈信息，该第j个上行数据是该终端设备使用对应于该第i个反馈信息的第i个混合自动重传请求进程发送的最后一个上行数据，该i∈[1,L]，该i为整数，该j为正整数。
具体而言，该终端设备#A可以使用多个并行的HARQ进程发送上行数据，即，当该终端设备#A在等待一个HARQ进程的反馈信息时，可以使用另一个HARQ进程来继续发送上行数据，提高数据的传输速率，同时，当一个HARQ进程的反馈信息确认后，可以继续在同样的HARQ进程上发送上行数据。
假设，系统配置的所有的HARQ进程为L个HARQ进程，由于该第二定时器是针对所有HARQ进程的，那么，在这种情况下，若该终端设备接收到与该L个HARQ进程对应的L个反馈信息，可以停止该第二定时器，其中，以对应于第i个HARQ进程的第i个反馈信息为例，该第i个反馈信息是在一定时段内该终端设备#A使用该第i个HARQ进程发送的最后一个上行数据的反馈信息。
在一定时段内(例如，网络设备连续调度终端设备的场景中)，该终端设备#A知道该网络设备会多次调度自己发送上行数据，在该第二定时器的运行期间，会一直监听下行控制信道，以便于接收下次发送的调度信息从而基于下次发送的调度信息来发送上行数据。当该终端设备#A接收到针对每个HARQ进程中的最后一个上行数据的反馈信息时，表示该网络设备暂时不会调度该终端设备#A发送数据，对于该终端设备#A来说，暂时不会使用该L个HARQ进程发送上行数据，那么，可以停止该第二定时器，以节省功耗。
需要说明的是，该第二定时器可以是非连续接收-非激活态定时器(Drx-inactivity Timer)，也可以是一个非连续接收周期中的工作时段的定时器(On Duration Timer)，本申请实施例并不限于此。
因此，本申请实施例提供的数据传输的方法，在针对所有HARQ进程的第二定时器的运行期间，若终端设备接收到针对每个HARQ进程中的最后一个上行数据的反馈信息，则停止该第二定时器，可以减少该终端设备的功耗。
可选地，本申请实施例中图9所对应的实施例可以单独应用，也可以与图1至图8所对应的任一个或者多个实施例结合使用。
以上，结合图1至图9详细描述了根据本申请实施例的数据传输的方法，下面，结合图10至图11描述根据本申请实施例的数据传输的装置，方法实施例所描述的技术特征同样适用于以下装置实施例。
