目前，在NB-IoT系统中，已经引入数据早传(early data transmission，EDT)特性。该EDT特性对于NB-IoT系统中的终端设备来说是可选(optional)的特性，即NB-IoT系统中的终端设备可以选择支持EDT特性，也可以选择不支持EDT特性。其中，EDT特性包括用户面(user plane，UP)-EDT和控制面(control plane，CP)-EDT。UP-EDT有能力上报机制，即当终端设备选择支持UP-EDT时，终端设备会通知网络设备该终端设备支持UP-EDT，因此网络设备可以获知终端设备是否支持UP-EDT。而对于CP-EDT，则没有能力上报机制，即无论终端设备是否支持CP-EDT，终端设备均不会告诉网络设备，因此网络设备无法获知该终端设备是否支持CP-EDT。
现有技术中，在某个终端设备不支持UP-EDT时，由于网络设备不知道该终端设备是否支持CP-EDT，因此网络设备不知道该终端设备是否支持EDT。考虑到不支持EDT的终端设备无法接收EDT-窄带物理随机接入信道(narrowband physical random access channel，NPRACH)配置信息，从而无法采用现有的推迟或延时(postpone)方式向网络设备发送上行数据，因此网络设备均按照终端设备不支持EDT的方式调度EDT-NPRACH，即如图1所示，网络设备向终端设备发送的EDT-NPRACH资源和指示给终端设备的窄带物理上行共享信道(narrowband physical uplink shared channel，NPUSCH)资源完全避开，从而使得终端设备可以在网络设备所指示的NPUSCH资源上向网络设备发送上行数据。
然而，由于上述方案需要EDT-NPRACH资源和NPUSCH资源完全避开，因此对于网络设备的调度灵活性有一定的限制，因此，如何在数据传输时，提高网络设备调度的灵活性，是目前亟待解决的问题。
发明内容

具体实施方式
为了方便理解本申请实施例的技术方案，首先给出本申请相关技术的简要介绍如下。
第一，IoT：
IoT是“物物相连的互联网”。它将互联网的用户端扩展到了任何物品与物品之间，使得在任何物品与物品之间可以进行信息交换和通信。这样的通信方式也称为机器间通信(machine type communications，MTC)。其中，通信的节点称为MTC终端或MTC设备。典型的IoT应用包括智能电网、智能农业、智能交通、智能家居以及环境 检测等各个方面。
由于物联网需要应用在多种场景中，比如从室外到室内，从地上到地下，因而对物联网的设计提出了很多特殊的要求。比如，由于某些场景下的MTC终端应用在覆盖较差的环境下，如电表水表等通常安装在室内甚至地下室等无线网络信号很差的地方，因此需要覆盖增强的技术来解决。或者，由于某些场景下的MTC终端的数量要远远大于人与人通信的设备数量，也就是说需要大规模部署，因此要求能够以非常低的成本获得并使用MTC终端。或者，由于某些场景下的MTC终端传输的数据包很小，并且对延时并不敏感，因此要求支持低速率的MTC终端。或者，由于在大多数情况下，MTC终端是通过电池来供电的，但是同时在很多场景下，MTC终端又要求能够使用十年以上而不需要更换电池，这就要求MTC终端能够以极低的电力消耗来工作。
为了满足上述需求，移动通信标准化组织3GPP在RAN#62次全会上通过了一个新的研究课题来研究在蜂窝网络中支持极低复杂度和低成本的物联网的方法，并且在RAN#69次会议上立项为NB-IoT课题。
第二，EDT：
现有的EDT流程示意图如图2所示，包括如下步骤：
S201、网络设备向终端设备发送EDT-NPRACH资源配置信息。相应的，终端设备接收来自网络设备的EDT-NPRACH资源配置信息。
其中，网络设备可以通过系统消息向终端设备发送EDT-NPRACH资源配置信息。该EDT-NPRACH资源配置信息可以包括nprach-ParametersListFmt2EDT-r15参数或者nprach-ParametersListEDT-r15参数，本申请实施例对此不作具体限定。
其中，EDT-NPRACH资源是用于终端设备请求数据早传的NPRACH资源。
此外，本申请实施例以及下述各实施例中的EDT-NPRACH资源均是周期性的资源，比如，上述图1中仅是示例性的给出了两个周期的EDT-NPRACH资源，在此统一说明，以下不再赘述。
S202、终端设备根据EDT-NPRACH资源配置信息，在EDT-NPRACH资源上向网络设备发送前导(preamble)。相应的，网络设备在EDT-NPRACH资源上接收来自终端设备的前导。
S203、网络设备向终端设备发送随机接入响应(random access response)。相应的，终端设备接收来自网络设备的RAR。
其中，该RAR中包括上行(uplink，UL)调度(grant)，该UL grant指示用于消息3传输的资源。
S204、终端设备向网络设备发送消息3(message 3，msg3)。相应的，网络设备接收来自终端设备的消息3。
S205、网络设备向终端设备发送消息4(message 4，msg4)。相应的，终端设备接收来自网络设备的消息4。
如背景技术中所述，EDT特性包括UP-EDT和CP-EDT。若终端设备支持CP-DET，则上述步骤S204中的消息3具体可以为无线资源控制(radio resource control，RRC)数据早传请求(RRC early data request)消息，上述步骤S205中的消息4具体可以为RRC数据早传完成(RRC early data complete)消息。或者，若终端设备支持UP-DET， 则上述步骤S204中的消息3具体可以为RRC连接恢复请求(RRC connection resume request)消息，上述步骤S205中的消息4具体可以为RRC连接释放(RRC connection release)消息。
其中，上述步骤S204中的消息3还可以为RRC连接请求NB(RRC connection request-NB)消息、RRC连接重建请求NB(RRC connection reestablishment request-NB)消息或者RRC连接恢复请求NB(RRC connection resume request-NB)消息等。消息4还可以为RRC连接建立NB(RRC connection setup-NB)消息、RRC连接恢复NB(RRC connection resume-NB)消息或者RRC连接重建NB(RRC connection reestablishment-NB)消息等。即表示可以回退到传统的随机接入过程中(legacy RACH)，本申请实施例对此不作具体限定。
需要说明的是，图2所示的EDT流程以应用在NB-IoT系统为例进行说明。其中，EDT流程也可以应用于增强的MTC(enhanced MTC，eMTC)系统中，此时对应的EDT流程与图2类似，区别比如在于，将NB-IoT系统中的EDT-NPRACH资源替换为eMTC系统中通过edt-PRACH-ParametersListCE-r15或者EDT-PRACH-ParametersCE-r15 IE配置的EDT随机接入资源。此外，eMTC系统中的随机接入信道为PRACH。其余可参考图2所示的实施例，在此不再赘述。
第三，下行控制信息(downlink control information，DCI)：
DCI中包含用于指示NPUSCH的起始位置的调度时延域，用于指示资源单元(resource unit，RU)的个数的资源分配域，以及用于指示数据重复次数的重复次数域。其中，RU中包括多个资源元素(resource element，RE)，RE时域上占据一个单载波频分多址(single-carrier frequency-division multiple access，SC-FDMA)符号，频域上占据一个子载波。RU的定义为频域上占用

个子载波，时域上占用

表三
Figure PCTCN2019116113-appb-000010
第四，postpone方式：
如图3所示，为现有的EDT-NPRACH资源和NPUSCH资源采用postpone方式避开的示意图。即，网络设备配置的EDT-NPRACH资源和网络设备指示的NPUSCH资源有重叠的情况下，实际用于传输上行数据的NPUSCH资源将避开网络设备配置的EDT-NPRACH资源。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。其中，在本申请的描述中，除非另有说明，“/”表示前后关联的对象是一种“或”的关系，例如，A/B可以表示A或B；本申请中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况，其中A,B可以是单数或者复数。并且，在本申请的描述中，除非另有说明，“多个”是指两个或多于两个。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b，或c中的至少一项(个)，可以表示：a，b，c，a-b，a-c，b-c，或a-b-c，其中a，b，c可以是单个，也可以是多个。另外，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
此外，本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
如图4所示，为本申请实施例提供的一种通信系统40。该通信系统40包括一个网络设备50，以及与该网络设备50连接的一个或多个终端设备60。下面以网络设备50与任一终端设备60进行交互为例进行说明。
其中，网络设备50确定满足第二预设条件的情况下，向终端设备60发送指示信息，该指示信息指示用于传输上行数据的第一资源，该第一资源与EDT物理随机接入信道资源有重叠。相应的，终端设备60接收来自网络设备50的指示信息。进而，终端设备60确定满足第一预设条件的情况下，推迟在第二资源上向网络设备50发送该上行数据。相应的，网络设备50推迟在第二资源上接收来自终端设备60的上行数据。
上述方案的具体实现将在下述实施例中详细阐述，在此不再赘述。
不需要像现有技术一样，在终端设备支持CP-EDT，但是网络设备不知道该终端设备是否支持EDT时，需要EDT-NPRACH资源和NPUSCH资源完全避开，从而限制了网络设备调度的灵活性。由于本申请实施例中，用于传输上行数据的第一资源可以与EDT物理随机接入信道资源有重叠。该EDT物理随机接入信道资源例如可以为EDT-NPRACH资源，该第一资源例如可以为NPUSCH资源。其中，在第一资源与EDT物理随机接入信道资源有重叠的情况下，若终端设备确定满足第一预设条件，或者，若网络设备确定满足第二预设条件，终端设备推迟在第二资源上向网络设备发送该上行数据。相应的，网络设备推迟在第二资源上接收来自终端设备的上行数据。也就是说，若终端设备确定满足第一预设条件，或者，若网络设备确定满足第二预设条件，则可以视为终端设备支持EDT，此时，第一资源与EDT物理随机接入信道资源可以有重叠，进而终端设备可以采用postpone方式向网络设备发送上行数据，因此，不仅可以在数据传输时，提高网络设备调度的灵活性，并且可以减少资源的浪费。

或者，可选的，一种可能的实现方式中，第二预设条件可以包括：网络设备在EDT物理随机接入信道资源上接收到随机接入前导，且网络设备向终端设备发送RAR，如图2所示的EDT流程中的步骤S202和步骤S203。其中，随机接入前导和RAR传输可以在同一个随机接入过程中。

或者，可选的，一种可能的实现方式中，第二预设条件可以包括：网络设备确定终端设备的高层触发EDT流程，比如，网络设备在EDT物理随机接入信道资源上接收到随机接入前导。
此外，第二预设条件还可能有其他的表征形式，本申请实施例对第二预设条件不作具体限定，该第二预设条件旨在说明终端设备之前使用过EDT物理随机接入信道资源，从而在网络设备获知终端设备不支持UP-DET的情况下，可以间接说明该终端设备支持CP-EDT，从而说明终端设备是支持EDT的。当然，若终端设备支持UP-EDT，由于UP-EDT有能力上报机制，即当终端设备选择支持UP-EDT时，终端设备会通知网络设备该终端设备支持UP-EDT，因此网络设备可以获知终端设备支持UP-EDT。在终端设备支持UP-EDT时，上述第二预设条件显然也是满足的。综上，只要网络设备确定满足第二预设条件，即可视为终端设备支持EDT。
示例性的，本申请实施例中的EDT物理随机接入信道资源例如可以是EDT-NPRACH资源，在此统一说明，以下不再赘述。
S602、网络设备向终端设备发送指示信息，该指示信息指示用于传输上行数据的第一资源，该第一资源与EDT物理随机接入信道资源有重叠。相应的，终端设备60接收来自网络设备50的指示信息。

一种可能的实现方式中，该指示信息例如可以是图2所示的EDT流程中步骤S203中的UL grant。此时相应的，第一资源为该UL grant所指示的用于上行数据传输的消息3的资源。也就是说，这里是用于上行数据传输的消息3的资源与EDT物理随机接入信道资源有重叠。
或者，一种可能的实现方式中，该指示信息可以是图2所示的EDT流程之后，终端设备进入连接态或者终端设备通过传统的随机接入(legacy RACH)进入连接态后终端设备接收到的DCI。此时相应的，第一资源为DCI所指示的上行数据传输的资源。可选的，该DCI的格式可以为DCI格式(format)N0。其中，DCI格式N0用于调度上行数据传输，包括用于指示NPUSCH的起始位置的调度时延域以及用于指示数据重复次数的重复次数域等。
示例性的，本申请实施例中的第一资源例如可以是NPUSCH资源。该NPUSCH资源的格式可以为NPUSCH格式1或NPUSCH格式2。
其中，在NB-IoT系统中，NPUSCH格式1或NPUSCH格式2对应的用于上行传输的资源可以如上述表一或者上述表二所示。在上述表一或表二中，NPUSCH格式1用于发送数据，NPUSCH格式2用于发送肯定应答(acknowledgement，ACK)或者否定应答(negative acknowledgement，NACK)。在表二所示的TDD NB-IoT系统中，对于NPUSCH格式1，当子载波间隔为3.75kHZ时，所支持的上下行子帧配置包括配置1或配置4。对于NPUSCH格式1，当子载波间隔为15kHZ时，所支持的上行或下 行配置包括配置1、配置2、配置3、配置4或配置5。其中，配置1、配置2、配置3、配置4或配置5可参考上述表三，在此不再赘述。此外，NPUSCH格式2的情况与NPUSCH格式1类似，在此不再赘述。
需要说明的是，本申请实施例中，在第一资源为NPUSCH资源，EDT物理随机接入信道资源为EDT-NPRACH资源的情况下，第一资源与EDT物理随机接入信道资源有重叠是指NPUSCH资源的任意一个RE和NPRACH资源重叠(overlap)，在此统一说明，以下不再赘述。
S603、终端设备确定满足第一预设条件。
可选的，一种可能的实现方式中，第一预设条件可以包括：终端设备在EDT物理随机接入信道资源上发送随机接入前导，如图2所示的EDT流程中的步骤S202。
或者，可选的，一种可能的实现方式中，第一预设条件可以包括：终端设备在EDT物理随机接入信道资源上发送过随机接入前导。
或者，可选的，一种可能的实现方式中，第一预设条件可以包括：终端设备在EDT物理随机接入信道资源上发送随机接入前导，终端设备接收到来自网络设备的RAR，如图2所示的EDT流程中的步骤S202和步骤S203。其中，随机接入前导和RAR传输可以在同一个随机接入过程中。
或者，可选的，一种可能的实现方式中，第一预设条件可以包括：终端设备在EDT物理随机接入信道资源上发送随机接入前导，终端设备接收到来自网络设备的RAR，终端设备发送消息3，如图2所示的EDT流程中的步骤S202至步骤S204。其中，随机接入前导、RAR传输和消息3传输可以在同一个随机接入过程中。

或者，可选的，一种可能的实现方式中，第一预设条件可以包括：终端设备的高层触发EDT流程，比如，终端设备在EDT物理随机接入信道资源上向网络设备发送随机接入前导。
此外，第一预设条件还可能有其他的表征形式，本申请实施例对第一预设条件不作具体限定，该第一预设条件旨在说明终端设备之前使用过EDT物理随机接入信道资源，即终端设备支持EDT，包括支持CP-EDT或UP-EDT。
S604、终端设备推迟在第二资源上向网络设备发送该上行数据。相应的，网络设备推迟在第二资源上接收来自终端设备的上行数据。其中，第二资源与EDT物理随机接入信道的资源没有重叠。
其中，本申请实施例中，由于上行数据被映射到NPUSCH上，因此，终端设备推迟在第二资源向网络设备发送上行数据，以及，网络设备推迟在第二资源上接收来自终端设备的上行数据，实际上是指，承载上行数据的NPUSCH传输(transmission)被推迟在第二资源上，在此统一说明，以下不再赘述。
示例性的，本申请实施例中的第二资源例如可以是NPUSCH资源。该NPUSCH资源的格式可以为NPUSCH格式1或NPUSCH格式2。相关描述可参考上述步骤S602，在此不再赘述。
也就是说，在第一资源与数据早传EDT物理随机接入信道资源有重叠的情况下， 上行数据被推迟在与EDT物理随机接入信道的资源没有重叠的第二资源上发送。这里的上行数据被推迟，可以是从上行数据的起始资源开始被推迟，也可以是从上行数据的中间资源开始被推迟，本申请实施例对此不作具体限定。比如，终端设备推迟在第二资源上向网络设备发送该上行数据例如可以是EDT-NPRACH资源和NPUSCH资源采用postpone方式避开。
其中，本申请实施例中，当步骤S602中的指示信息是图2所示的EDT流程中步骤S203中的UL grant时，第一资源为该UL grant所指示的用于上行数据传输的消息3的资源。在用于上行数据传输的消息3的资源与EDT物理随机接入信道资源有重叠的情况下，消息3被推迟在与EDT物理随机接入信道的资源没有重叠的第二资源上发送。
其中，一种可能的实现方式中，第二资源中包括m个第一资源块，EDT物理随机接入信道的资源中包括m个第二资源块；其中，m个第一资源块中的第i个第一资源块的起始位置为m个第二资源块中第i个第二资源块的结束位置的下一个资源位置，m为正整数，i为不大于m的正整数。

可选的，m个第一资源块中的第j个第一资源块的结束位置为m个第二资源块中第j+1个第二资源块的起始位置的上一个资源位置，j为小于m的正整数。
示例性的，以第一资源为指示的NPUSCH资源，EDT物理随机接入信道资源为EDT-NPRACH资源为例，则如图7所示，第二资源(即实际占用的NPUSCH资源)中包括1个第一资源块(即m＝1)，EDT-NPRACH资源中包括1个第二资源块，其中，第1个第一资源块的起始位置为第1个第二资源块的结束位置的下一个资源位置，第1个第一资源块的结束位置为第1个第二资源块的结束位置与下一个第二资源块的起始位置之间的一个资源位置。
示例性的，以第一资源为指示的NPUSCH资源，EDT物理随机接入信道资源为EDT-NPRACH资源为例，则如图8所示，第二资源(即实际占用的NPUSCH资源)中包括2个第一资源块(即m＝2)，EDT-NPRACH资源中包括2个第二资源块，其中，第1个第一资源块的起始位置为第1个第二资源块的结束位置的下一个资源位置，第1个第一资源块的结束位置为第2个第二资源块的起始位置的上一个资源位置。第2个第一资源块的起始位置为第2个第二资源块的结束位置的下一个资源位置，第2个第一资源块的结束位置为第2个第二资源块的结束位置与下一个第二资源块的起始位置之间的一个资源位置。
或者，示例性的，以第一资源为指示的NPUSCH资源，EDT物理随机接入信道资源为EDT-NPRACH资源为例，则如图9所示，第二资源(即实际占用的NPUSCH资源)中包括3个第一资源块(即m＝3)，EDT-NPRACH资源中包括3个第二资源块，其中，第1个第一资源块的起始位置为第1个第二资源块的结束位置的下一个资源位置，第1个第一资源块的结束位置为第2个第二资源块的起始位置的上一个资源位置。第2个第一资源块的起始位置为第2个第二资源块的结束位置的下一个资源位置，第2个第一资源块的结束位置为第3个第二资源块的起始位置的上一个资源位置。第3个第一资源块的起始位置为第3个第二资源块的结束位置的下一个资源位置，第3个 第一资源块的结束位置为第3个第二资源块的结束位置与下一个第二资源块的起始位置之间的一个资源位置。
其中，上述图7至图9所示的示例均是对应从上行数据的起始资源开始被推迟的场景。
另一种可能的实现方式中，第二资源中包括n+1个第一资源块，EDT物理随机接入信道的资源中包括n个第二资源块，n+1个第一资源块中第1个第一资源块的起始位置与第一资源的起始位置相同；n+1个第一资源块中第i+1个第一资源块的起始位置为n个第二资源块中第i个第二资源块的结束位置的下一个资源位置，n为正整数，i为不大于n的正整数。
可选的，n+1个第一资源块中第j个第一资源块的结束位置为n个第二资源块中第j个第二资源块的起始位置的上一个资源位置，j为不大于n的正整数。
示例性的，以第一资源为指示的NPUSCH资源，EDT物理随机接入信道资源为EDT-NPRACH资源为例，则如图10所示，第二资源(即实际占用的NPUSCH资源)中包括2个第一资源块(即n＝1)，EDT-NPRACH资源中包括1个第二资源块，其中，第1个第一资源块的起始位置与第一资源的起始位置相同,第1个第一资源块的结束位置为第1个第二资源块的起始位置的上一个资源位置。第2个第一资源块的起始位置为第1个第二资源块的结束位置的下一个资源位置，第2个第一资源块的结束位置为第1个第二资源块的结束位置与下一个第二资源块的起始位置之间的一个资源位置。
或者，示例性的，以第一资源为指示的NPUSCH资源，EDT物理随机接入信道资源为EDT-NPRACH资源为例，则如图11所示，第二资源(即实际占用的NPUSCH资源)中包括3个第一资源块(即n＝2)，EDT-NPRACH资源中包括2个第二资源块，其中，第1个第一资源块的起始位置与第一资源的起始位置相同,第1个第一资源块的结束位置为第1个第二资源块的起始位置的上一个资源位置。第2个第一资源块的起始位置为第1个第二资源块的结束位置的下一个资源位置，第2个第一资源块的结束位置为第2个第二资源块的起始位置的上一个资源位置。第3个第一资源块的起始位置为第2个第二资源块的结束位置的下一个资源位置，第3个第一资源块的结束位置为第2个第二资源块的结束位置与下一个第二资源块的起始位置之间的一个资源位置。
其中，上述图10和图11所示的示例均是对应从上行数据的中间资源开始被推迟的场景。
综上，本申请实施例中，第一资源与EDT物理随机接入信道资源有重叠情况下,终端设备将第一资源中的重叠部分的上行发送推迟到下一个与NPRACH资源不重叠的资源上发送。
可选的，本申请实施例中的资源位置可以为一个无线帧、一个系统帧、一个超帧，或者一个时隙，符号等，本申请实施例对此不作具体限定。
可选的，本申请实施例中，在FDD NB-IoT系统中，对于NPUSCH格式1，上行数据在NPUSCH资源上传输时，每间隔256ms，会插入一个40ms的间隔(gap)，在40ms的间隔结束后，继续在NPUSCH资源上传输上行数据。也就是说，在NPUSCH资源上传输的上行数据需要被postpone。
不需要像现有技术一样，在终端设备支持CP-EDT，但是网络设备不知道该终端设备是否支持EDT时，需要EDT-NPRACH资源和NPUSCH资源完全避开，从而限制了网络设备调度的灵活性。由于本申请实施例中，用于传输上行数据的第一资源可以与EDT物理随机接入信道资源有重叠。该EDT物理随机接入信道资源例如可以为EDT-NPRACH资源，该第一资源例如可以为NPUSCH资源。其中，在第一资源与EDT物理随机接入信道资源有重叠的情况下，若终端设备确定满足第一预设条件，或者，若网络设备确定满足第二预设条件，终端设备推迟在第二资源上向网络设备发送该上行数据。相应的，网络设备推迟在第二资源上接收来自终端设备的上行数据。也就是说，若终端设备确定满足第一预设条件，或者，若网络设备确定满足第二预设条件，则可以视为终端设备支持EDT，此时，第一资源与EDT物理随机接入信道资源可以有重叠，进而终端设备可以采用postpone方式向网络设备发送上行数据，因此，不仅可以在数据传输时，提高网络设备调度的灵活性，并且可以减少资源的浪费。
其中，上述步骤S601至S604中的网络设备的动作可以由图5所示的网络设备50中的处理器501调用存储器502中存储的应用程序代码以指令该网络设备执行，上述步骤S601至S604中的终端设备的动作可以由图5所示的终端设备60中的处理器601调用存储器602中存储的应用程序代码以指令该网络设备执行，本实施例对此不作任何限制。
可选的，本申请实施例中，若网络设备确定不满足预设条件，可以采用现有的EDT-NPRACH资源和NPUSCH资源完全避开的方式进行处理，即网络设备向终端设备发送指示信息，该指示信息指示用于传输上行数据的第三资源，该第三资源与EDT物理随机接入信道资源没有重叠。相应的，终端设备接收来自网络设备的指示信息，进而终端设备在第三资源上向网络设备发送上行数据。相应的，网络设备在第三资源上接收来自终端设备的上行数据。相关实现可参考现有的方式，在此不予赘述。
需要说明的是，上述实施例均是以数据接收和发送的方法应用在NB-IoT系统为例进行说明。当然，本申请实施例提供的数据接收和发送的方法也可以应用在eMTC系统中，此时对应的方案与上述实施例中的方案类似。区别比如在于，将NB-IoT系统中的NPUSCH资源替换为eMTC系统中的eMTC物理上行共享信道(physical uplink shared channel，PUSCH)资源或者物理上行控制信道(physical uplink control channel，PUCCH)资源，将NB-IoT系统中的EDT-NPRACH资源替换为eMTC系统中通过edt-PRACH-ParametersListCE-r15或者EDT-PRACH-ParametersCE-r15 IE配置的EDT随机接入资源。此外，eMTC系统中的随机接入信道为PRACH。其余相关描述可参考上述实施例，在此不再赘述。

可选的，上述预设条件可以包括：终端设备在EDT物理随机接入信道资源上发送随机接入前导，终端设备接收到来自网络设备的RAR。或者，上述预设条件可以包括：终端设备执行过EDT流程。
