在本实施例中提供了一种信号的发送方法，图2是根据本公开实施例的信号的发送方法的流程图，如图2所示，该流程包括如下步骤：
步骤S202，发送第一信号，其中，第一信号包括一个或多个符号组。
通过上述步骤，由于终端在向基站发送第一信号时，对第一信号进行配置，使得第一信号包括至少一个符号组。因此，可以解决相关技术中基于NB-IoT系统的信号不支持在大小区的覆盖以及时分双工模式下工作的问题，达到基于NB-IoT系统的信号可以在大小区的覆盖以及时分双工模式下工作的效果。
可选地，上述步骤的执行主体可以为一个或者一组终端等，但不限于此。
在本实施例中，符号组包括以下之一：循环前缀和至少一个符号，循环前缀、至少一个符号和保护时间；符号组中的各个符号组在频域上占用相同的子载波或者占用相同的频率资源。
在一个可选的实施例中，当上述第一信号包括6个符号组时，上述6个符号组中各个相邻符号组之间占用的子载波索引的差值包括以下至少之一：a1，-a1，a2，-a2，a3，-a3；其中，a1、a2、a3均为大于等于1的整数，且上述a1小于等于上述a2，上述a2小于等于上述a3。在本实施例中，相邻符号组指的是 符号组的索引相邻，相邻的2个符号组占用的时域资源位置可以是时域上相邻或者时域上离散，优选为时域上相邻。此外，根据子载波索引可以确定符号组占用的子载波，由于每个子载波都占用具体的频域资源，因此，可以计算到每个子载波占用的频域资源位置。优选的子载波间隔为1.25kHz。按照上述配置，相邻的2个符号组占用的频域资源位置相差可以包括：+/-1.25kHz，+/-3.75kHz和+/-22.5kHz。上述中的差值可以是a1，-a1，a2，-a2，a3，-a3中的任一项，也可以是其中的任意组合，比如6个符号组中的第一符号组和第二个符号组之间的差值是a1或-a1。
在一个可选的实施例中，上述6个符号组中的各符号组占用的子载波索引包括下面值中的任意组合或者是单独的一个值：k，k+a1，k，k-a2，k，k+a3；k，k-a1，k，k-a2，k，k+a3；k，k+a1，k，k+a2，k，k+a3；k，k-a1，k，k+a2，k，k+a3；k，k+a1，k，k-a2，k，k-a3；k，k-a1，k，k-a2，k，k-a3；k，k+a1，k，k+a2，k，k-a3；k，k-a1，k，k+a2，k，k-a3；其中，上述k为大于等于0的整数。在本实施例中，上述仅是优选的配置，其他配置详见具体实施例中的阐述。比如，上述中的6个符号组中的第一个符号组占用的子载波索引是k或者是k+a1，也可以是上述值中任意取值。

具体的资源配置方案如下：
方案1：

图8所示的方案1具体描述如下：
第一信号发送时占用的符号组为符号组0～符号组5，其中，每个符号组在频域上占用1个子载波。所述6个符号组分布在第一时频资源块内，其中，第一时频资源块的频域包括36个子载波，编号为子载波0～子载波35(这里的子载波索引是一个相对索引，用来描述第一时频资源块内的子载波的分布情况)；时频资源块的时域长度为符号组0～符号组5(这里的符号组索引是一个相对索引，用来描述第一时频资源块内的符号组的分布情况)的6个符号组的时域长度之和。图8中，每个符号组都有36个可以占用的子载波，即有36个可用的资源。针对符号组0～符号组5，可以组成36条互相独立的发送资源组合，即为信道。例如，组成“信道0”的6个符号组占用的子载波为：从每个符号组可选的子载波资源中选择标记为“信道0”的子载波，即符号组0所在的子载波索引为0，符号组1所在的子载波索引为1，符号组2所在的子载波索引为0，符号组3所在的子载波索引为3，符号组4所在的子载波索引为0，符号组5所在的子载波索引为18。信道1～信道35的生成方式以此类推，如图8中所示。
方案2：

具体配置方案如下：
方案1：
b1优选为1，b2优选为18，如图21所示，9个符号组分布于第一时频资源块内，第一时频资源块频域上占用36个子载波，第一时频资源块时域上的长度为9个符号组对应的时域长度。
第一信号发送时占用的符号组为符号组0～符号组8，其中，每个符号组在频域上占用1个子载波。9个符号组分布在第一时频资源块内，其中，第一时频资源块的频域包括36个子载波，编号为子载波0～子载波35(这里的子载波索引是一个相对索引，用来描述第一时频资源块内的子载波的分布情况)；时频资源块的时域长度为符号组0～符号组8(这里的符号组索引是一个相对索引，用来描述第一时频资源块内的符号组的分布情况)的9个符号组的时域长度之和。图21中，每个符号组都有33个可以占用的子载波，即有33个可用的资源。针对符号组0～符号组8，可以组成33条互相独立的发送资源组合，即为信道。例如，组成“信道0”的9个符号组占用的子载波为：从每个符号组可选的子载波资源中选择标记为“信道0”的子载波，即符号组0所在的子载波索引为0，符号组1所在的子载波索引为1，符号组2所在的子载波索引为2，符号组3所在的子载波索引为3，符号组4所在的子载波索引为2，符号组5所在的子载波索引为1，符号组6所在的子载波索引为0，符号组7所在的子载波索引为18，符号组8所在的子载波索引为0。信道1～信道33的生成方式以此类推，具体如图21所示。

具体实施例7：
当第一信号为随机接入信号时，第二节点接收到第一节点发送的随机接入信号之后，向第一节点发送随机接入响应消息。其中，第二节点为基站或中继。
随机接入响应消息中至少包括MAC头(MAC header)和MAC层负载(MAC Payload)。其中，MAC头中包括至少一个MAC子头(MAC subheader)。
MAC子头包括一种或多种类型的MAC子头，一种类型的MAC子头由8bit组成，其中的K bit用来表示RAPID，其中，K优选为6。
其中，RAPID可以指示以下至少之一：第一集合的索引，其中，集合为N(N为大于等于1的整数，优选为3)个随机接入信号中第一个符号组所在的子载波；
RAPID＝Index/M，其中，Index为随机接入信号中第一个符号组所在的子载波索引，M为大于等于1的整数，优选为3；RAPID为大于等于0的整数。
当RAPID为第一集合的索引时，MAC层负载中至少有一个MAC RAR与RAPID对应，并且在MAC RAR中包括一个指示信息，通过指示信息指示MAC RAR对应的子载波在第一集合中的索引。
当RAPID＝Index/M时，MAC层负载中至少有一个MAC RAR与RAPID对 应，并且在MAC RAR中包括一个指示信息，通过指示信息指示MAC RAR对应的子载波在第二集合中的索引。其中，第二集合包括子载波索引为[RAPID，(RAPID+1)*M-1]的子载波。
一个NB-IOT系统，系统带宽为180kHz，随机接入信号对应的子载波间隔为1.25kHz，则系统带宽内最多可以配置144个随机接入信号的子载波，子载波索引为0～143。当基站接收到终端发送的随机接入信号之后，发送随机接入响应消息(Random Access Response，RAR)给终端。其中RAR消息是通过控制信道调度的。即RAR消息的调度信息包含在下行控制信息(Downlink Control Information，DCI)中，所述DCI通过控制信道发送。所述DCI信息中还包括循环冗余校验码CRC，并且所述CRC采用随机接入无线网络临时标识(RA-RNTI)进行加扰的；其中，1.25kHz子载波间隔的随机接入信号的RAR消息对应RA-RNTI取值范围与其他子载波间隔的随机接入信号的RAR消息对应RA-RNTI取值范围不同。
例如，当3.75kHz子载波间隔的随机接入信号的RAR消息对应RA-RNTI取值范围为1+floor(SFN_id/4)+256*carrier_id时，1.25kHz子载波间隔的随机接入信号的RAR消息对应RA-RNTI取值范围为RA-RNTI＝4096+1+floor(SFN_id/4)+256*carrier_id。其中，SFN_id为随机接入信号发送时起始位置所对应的帧的编号。carrier_id为随机接入信号发送时占用的载波编号。
随机接入响应消息中至少包括MAC头(MAC header)和MAC层负载(MAC Payload)，如图22所示。
其中，MAC头中包括多个MAC子头(MAC subheader)，由2种类型的子头构成，其中，子头类型1的结构如图23所示，子头类型2的结构如图24所示。
在图23和图24中：
-E:用来指示MAC头中，当前的MAC子头后面是否还有其他的MAC子头。E为“1”代表当前的MAC子头后面还有其他的MAC子头E为“0”代表当前的MAC子头后面没有其他的MAC子头。
-T:代表当前MAC子头中T之后承载的是RAPID或者回退指示信息(Backoff Indicator，BI)。T为“0”代表当前MAC子头中T之后承载的是BI，T为“1”代表当前MAC子头中T之后承载的是RAPID。
-R:为保留比特，配置为“0”。
在本实施例中，子头类型1由8bit组成，其中的6 bit用来表示RAPID。其中，RAPID为第一集合的索引，其中，第一集合为3个随机接入信号中第一个符号组所在的子载波；本实施例中，由于最多可以配置144个随机接入信号的子载波，因此，可以配置最多48个所述第一集合，第一集合的索引分别为0～47，通过6 bit的RAPID指示，例如，RAPID＝0为索引为0的第一集合，对应的随机接入信号中第一个符号组所在的子载波为0,1,2；RAPID＝1为索引为1的第一集合，对应的随机接入信号中第一个符号组所在的子载波为3,4,5；以此类推，RAPID＝47为索引为47的第一集合，对应的随机接入信号中第一个符号组所在的子载波为141,142,143。
MAC层负载中有一个MAC RAR与RAPID对应，MAC RAR的结构如图25所示。本实施例中，RAPID＝1，则对应的随机接入信号中第一个符号组所在的子载波为3,4,5。在MAC RAR中包括一个指示信息，通过所述指示信息指示所述MAC RAR对应的子载波在子载波3,4,5中的具体取值。
图25中，R为保留比特，本实施例中R为6bit，Timing Advance Command承载的是定时提前的调整量，本实施例中长度为11bit；UL Grant承载的是上行调度信息，本实施例中长度为15bit；Temporary C-RNTI为临时的小区无线网络临时标识(Temporary Cell Radio Network Temporary Identifier)，本实施例中长度为16bit。
本实施例中，所述指示信息长度为2bit，利用的是图25中的5比特长的“R”区域中的2bit。所述指示信息为“01”表示MAC RAR对应的子载波在子载波3,4,5中的第一个，即子载波3。所述指示信息为“10”表示MAC RAR对应的子载波在子载波3,4,5中的第二个，即子载波4。所述指示信息为“11”表示MAC RAR对应的子载波在子载波3,4,5中的第三个，即子载波5。
除本实施例外，MAC层负载中有三个MAC RAR与RAPID对应，MAC RAR的结构如图25所示。本实施例中，RAPID＝1，则对应的随机接入信号中第一个符号组所在的子载波为3,4,5。在MAC RAR中包括一个指示信息，通过所述指示信息指示所述MAC RAR对应的子载波在子载波3,4,5中的具体取值。
本实施例中，所述指示信息长度为2bit，利用的是图25中的5比特长的“R”区域中的2bit。所述指示信息为“01”表示MAC RAR对应的子载波在子载波3,4,5中的第一个，即子载波3。所述指示信息为“10”表示MAC RAR对应的子载波在子载波3,4,5中的第二个，即子载波4。所述指示信息为“11”表示MAC  RAR对应的子载波在子载波3,4,5中的第三个，即子载波5。
在本实施例中，三个MAC RAR中的2bit长度的指示信息分别为“01”，“10”和“11”，则表示三个MAC RAR对应的子载波在子载波3,4,5中分别为3,4和5。
