Description

通信方法、装置及系统 技术领域
本申请涉及通信领域，尤其涉及通信方法、装置及系统。
背景技术
当终端设备有上行数据需要传输时，现有的流程通常包括：终端设备有上行数据到达—终端设备向网络设备申请上行传输资源—网络设备向终端设备发送上行传输调度信息—终端设备根据该上行传输调度信息进行上行传输—网络设备根据上行数据的解调情况向终端设备反馈上行数据是否接收成功。
随着物联网(internet of things，IoT)技术的发展，IoT应用对IoT设计的需求也越来越高。为了满足这些需求，移动通信标准化组织第三代合作伙伴计划(3rd generation partnership project，3GPP)在无线接入网络(radio access network，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次会议上立项为窄带物联网(narrow band internet of thing，NB-IoT)课题。目前，NB-IoT版本(release)16正在研究上行(uplink，UL)免调度传输(grant-free transmission)，其流程包括：终端设备有上行数据到达—终端设备直接在预先配置的资源(preconfigured resources)上按照预先规定的发送方式进行上行传输—网络设备根据上行数据的解调情况向终端设备反馈上行数据是否接收成功。可以看出，对于上行免调度传输，由于终端设备不需要向网络设备申请上行传输资源，以及不需要等待网络设备向终端设备发送上行传输调度信息，即减少了流程，因此具有降低功耗时延、降低信令开销等优势。特别的，在上行免调度传输中，网络设备可以给不同的终端设备配置不同的上行免调度传输资源(dedicated resource)，也可以给不同的终端设备配置相同或部分重叠的上行免调度传输资源(shared resource)。相对于dedicated resource，shared resources有利于降低网络资源的开销，提升频谱利用率。
此外，在NB-IoT系统中，由于终端设备的低成本需求，配备较低成本晶振的终端设备在连续长时间的上行传输时，可能会产生晶振频率偏移，这样会严重影响到终端设备上行的传输性能，进而降低上行数据的传输效率。为了纠正这种频率偏移，现有技术引入了上行gap，即终端设备在上行数据每传输256ms后会插入40ms的gap。
然而，按照现有的上行gap插入机制，当同一小区的不同终端设备在shared resource上传输上行数据时，若多个终端设备发送上行数据的起始位置不一样，即使多个终端设备在插入40ms gap之前，各自的参考信号(如解调参考信号(demodulation reference signal，DMRS))正交，也无法保证多个终端设备在插入40ms gap之后，各自的参考信号正交。
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或名词的简要介绍如下。
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，上行数据传输：
和长期演进(long term evolution，LTE)不同，NB-IoT上行数据传输支持单频音(single-tone)和多频音(multi-tone)。single-tone传输对应的子载波个数为1，主要适用于低速率、覆盖场景增强的场景，可以提供更低实现成本；multi-tone传输对应的子载波个数大于1，可以比Single-tone传输提供更大速率，也可以支持覆盖增强。此外，NB-IoT上行传输的子载波间隔有15kHz和3.75kHz两种，当子载波个数为1(single-tone)时，支持15kHz和3.75kHz两种子载波间隔，当子载波个数大于1(multi-tone)时，只支持15kHz的子载波间隔。
上行数据传输的基本调度单位是资源单元(resource unit，RU)。当子载波间隔为3.75kHz时，NB-IoT系统只支持single-tone，1个RU在频域上占用1个子载波， 时域上占用16个时隙(slot)；当子载波间隔为15kHz时，表一定义了以下几种RU(

表示1个RU频域上占用的子载波数，
Figure PCTCN2019074719-appb-000002
表示1个RU时域上占用的连续slot数)，每个slot由7个单载波频分多址(single-carrier frequency-division multiple access，SC-FDMA)符号(symbol)组成。
表一
Figure PCTCN2019074719-appb-000003
此外，上行数据传输可能有重复(repetition)，一个数据块占M个RU，repetition数＝N，则表示本次上行传输占据N*M个RU，即重复(repetition)是以M*RU为单位的。
第三，DMRS：
NB-IoT窄带物理上行共享信道(narrow band physical uplink shared channel，NPUSCH)格式(format)1用于上行数据传输。其中，在上行数据传输过程中，终端设备会同时发送DMRS，DMRS用于网络设备进行信道估计、信道均衡，以便正确解调上行数据。如图1a所示，在进行上行数据传输时，1个slot中有1个SC-FDMA symbol用于传输DMRS、其余6个SC-FDMA symbol用于传输上行数据。其中，图1a中的保护间隔(guard period，GP)可参考现有的相关描述，在此不予赘述。
如上所述，对于上行数据传输来说，有两种传输方式：single tone和multi tone。对于single tone来说，有3.75kHz和15kHz两种子载波间隔，不论是哪种子载波间隔，对于single tone，一个RU占用16个slot。single tone的3.75kHz和15kHz在DMRS的生成方式上是一样的，仅是DMRS在映射上有所不同。具体DMRS在上行数据传输时如何映射，可参考现有的相关描述，本申请实施例对此不作具体限定。
示例性的，可以结合下述公式(1)和公式(2)生成DMRS：

其中，c()表示金(Gold)序列，且现有技术中，c()在NPUSCH传输开始位置进行初始化，初始化种子为C init＝35；w()表示哈达码(Hadamard)序列；r u(n)表示DMRS序列；

下面对Gold序列的生成方法进行说明。
其中，Gold序列c(n)的生成方式如下述公式(3)所示：
c(n)＝(x 1(n+N C)+x 2(n+N C))mod 2；                                 公式(3)
其中，将Gold的长度记为M PN，即n的取值范围为：0，1，……M PN-1，x 1(n+N C)、x 2(n+N C)为生成c(n)的两个序列，N C＝1600，mod()表示取余。
上述的序列x 1(n+N C)可以通过如下公式(4)确定：
x 1(n+31)＝(x 1(n+3)+x 1(n))mod 2；                                  公式(4)
其中，序列x 1(n+N C)的初始化种子为x 1(0)＝1,x 1(n)＝0,n＝1,2,......30。
上述的序列x 2(n+N C)可以通过如下公式(5)确定：
x 2(n+31)＝(x 2(n+3)+x 2(n+2)+x 2(n+1)+x 2(n))mod 2；                公式(5)
其中，可选的，序列x 2(n+N C)的初始化种子的取值与具体的应用有关，在DMRS序列的生成中，序列x 2(n+N C)的初始化种子为35。通过公式
Figure PCTCN2019074719-appb-000008
以及C init＝35可以得到序列x 2(n+N C)。
16长Hadamard序列w()如下表二所示：
表二
Figure PCTCN2019074719-appb-000009
其中，表二中的u为Hadamard序列w()的索引。不同的Hadamard序列w()的索引对应的Hadamard序列相互正交。对于single tone来说，不论是哪种子载波间隔，一个RU占用16个slot，这16个slot可以对应一个16长Hadamard序列w()。若同一小区的不同终端设备在shared resource上传输上行数据时，当不同终端设备的RU边界无法对齐时，即使不同终端设备对应不同的Hadamard序列索引u，不同终端设备在相同时频资源上使用的Hadamard序列不正交；当不同终端设备的RU边界对齐时，且不同终端设备对应不同的Hadamard序列索引u，不同终端设备在相同时频资源上使用的Hadamard序列正交。
现有技术中，组跳场景下Hadamard序列w()的索引u的计算公式与不组跳场景下 Hadamard序列w()的索引u的计算公式不同。
不组跳场景下Hadamard序列w()的索引u的计算公式如下述公式(6)所示：

根据上述公式(6)，示例性的，以一个数据块占用2个RU、NPUSCH重复2次，共4个RU为例，则小区标识和RU使用的Hadamard序列的索引u的映射关系可以如表三所示。由表三可知，此时，每个RU上使用的Hadamard序列的索引u相同；同频小区之间，如0号小区和16号小区，使用的Hadamard序列的索引u完全相同。

根据上述公式(7)至公式(9)，示例性的，以一个数据块占用2个RU、NPUSCH重复2次，共4个RU为例，此时，可以通过f gh(n s)和f ss确定Hadamard序列的索引u。其中，小区标识和RU使用的Hadamard序列的索引u的映射关系可以如表四所示。由表四可知，此时，每个RU上使用的Hadamard序列的索引u不相同；同频小区之间，如0号小区和16号小区，使用的Hadamard序列的索引u也不相同。

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。同时，在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念，便于理解。
本申请实施例可以适用于LTE系统，如NB-IoT系统中；也可以适用于其他无线通信系统，例如全球移动通信系统(Global System for Mobile Communication，GSM)，移动通信系统(Universal Mobile Telecommunications System，UMTS)，码分多址接入(Code Division Multiple Access，CDMA)系统，宽带码分多址(Wideband Code Division Multiple Access，WCDMA)以及面向未来的新的网络设备系统等，本申请实施例对此不作具体限定。其中，上述适用本申请的通信系统仅是举例说明，适用本申请的通信系统不限于此，在此统一说明，以下不再赘述。此外，术语“系统”可以和“网络”相互替换。
由上述公式(1)和上述公式(2)可知，当同一小区的不同终端设备在shared resource上传输上行数据时，若不同终端设备对应的Hadamard序列正交，Gold序列相同，则可以保证不同终端设备各自的参考信号正交。现有技术中，上行数据传输的时长和/或由于上行数据与随机接入信道碰撞所推迟的时长256ms之后，插入40ms用于推迟上行数据传输的gap。这样，当同一小区的不同终端设备在shared resource上传输上行数据时，若多个终端设备发送上行数据的起始位置不一样，即使多个终端设备在插入40ms gap之前，各自的参考信号(如DMRS)正交，也无法保证多个终端设备在插入40ms gap之后，各自的参考信号正交。
比如，以shared resource的子载波间隔为15kHz，一个RU＝8ms为例，如图1b所示，假设同一小区的UE1和UE2在shared resource上传输上行数据时，UE1发送上行数据的起始位置与UE2发送上行数据的起始位置不同，UE1插入40ms(对应5个RU)gap之前，UE1和UE2对应的Hadamard序列正交，UE1和UE2对应的Gold序列相同，因此UE1对应的DMRS和UE2对应的DMRS正交。在UE1插入40ms gap之后的第一个slot上，UE1对应的DMRS的生成公式(1)和公式(2)中的n的取值为16m+16，UE2对应的DMRS的生成公式(1)和公式(2)中的n的取值为16m+16×6，m为正整数，则根据上述Hadamard序列和Gold序列的描述可知，此时，RU边界对齐，在相同的时频资源上，UE1对应的Hadamard序列和UE2对应的Hadamard序列正交，但是UE1对应的Gold序列和UE2对应的Gold序列不同，从而无法保证在UE1插入40ms gap之后，UE1对应的DMRS和UE2对应的DMRS正交。
或者，比如，以shared resource的子载波间隔为3.75kHz，一个RU＝32ms为例，如图1c所示，假设同一小区的UE1和UE2在shared resource上传输上行数据时，UE1发送上行数据的起始位置与UE2发送上行数据的起始位置不同，UE1插入40ms gap(对应1个RU+4个时隙)之前，UE1和UE2对应的Hadamard序列正交，UE1和UE2对应的Gold序列相同，因此UE1对应的DMRS和UE2对应的DMRS正交。在UE1插入40ms gap之后的第一个slot上，UE1对应的DMRS的生成公式(1)和公式(2)中的n的取值为16m+16，UE2对应的DMRS的生成公式(1)和公式(2)中的n的取值为16m+16×1+5，m为正整数，则根据上述Hadamard序列和Gold序列的描述可知，此时，RU边界不对齐，在相同的时频资源上，UE1对应的Hadamard序列和UE2对应的Hadamard序列不正交，且UE1对应的Gold序列和UE2对应的Gold序列不同，从而无法保证在UE1插入40ms gap之后，UE1对应的DMRS和UE2对应的DMRS正交。
基于此，如图2所示，为本申请实施例提供的一种通信系统20。该通信系统20包括网络设备30以及该网络设备30所覆盖的第一小区内的多个终端设备40，该多个终端设备40能够在相同的上行时频资源上传输上行数据。可选的，多个终端设备40中的不同终端设备之间可以相互通信。第一小区可以为该网络设备30所覆盖的一个或多个小区中的任意一个小区。
以多个终端设备40中包括第一终端设备，该第一终端设备为多个终端设备40中的任一终端设备为例，本申请实施例中，第一终端设备根据预配置的上行时频资源确定参考时域位置，该参考时域位置与多个终端设备中的其他终端设备确定的参考时域位置相同；第一终端设备将距离参考时域位置(第一时长*N+第二时长*(N-1))的时域位置确定为X个时间间隔的起始时域位置，N为1，2，3，4，…，X，该X个时间间隔均不用于发送上行数据，X为正整数；第一终端设备将距离参考时域位置第一时长*(M-1)+第二时长*(M-1))的时域位置确定为Y个第一时长的起始时域位置；其中，Y个第一时长中的至少一个第一时长对应的时域资源中的全部或部分为用于传输上行数据的第一时频资源中的时域资源，M为1，2，3，4，…，Y，Y＝X或者Y＝X+1；第一终端设备在第一时频资源上向网络设备30发送上行数据。相应的，网络设备30根据预配置的上行时频资源确定该参考时域位置；网络设备30将距离该参考时域位置(第一时长*N+第二时长*(N-1))的时域位置确定为X个时间间隔的起始时域位置；网络设备30将距离参考时域位置第一时长*(M-1)+第二时长*(M-1))的时域位置确定为Y个第一时长的起始时域位置；网络设备30在第一时频资源上接收来自第一终端设备的上行数据。基于该方案，由于同一小区的能够在相同上行时频资源上传输上行数据的多个终端设备对应相同的参考时域位置，并且距离参考时域位置(第一时长*N+第二时长*(N-1))的时域位置为X个时间间隔的起始时域位置，因此对于同一小区的能够在相同上行时频资源上传输上行数据的多个终端设备来说，即使多个终端设备发送上行数据的起始位置不一样，也可以保证插入的第二时长的时间间隔的起始位置和结束位置均对齐，进而若多个终端设备在插入第二时长的时间间隔之前，各自的参考信号正交，也可以保证多个终端设备在插入第二时长的时间间隔之后，各自的参考信号正交。
需要说明的是，本申请实施例中的“*”与“×”含义相同，均表示相乘，在此统一说明，以下不再赘述。
需要说明的是，本申请实施例旨在解决若多个终端设备在插入第二时长的时间间隔之前，各自的参考信号(如DMRS)正交，如何保证多个终端设备在插入第二时长的时间间隔之后，各自的参考信号正交的问题，对于如何保证多个终端设备在插入第二时长的时间间隔之前，各自的参考信号正交，本申请实施例对此不作具体限定。示例性的，多个终端设备中的任意一个终端设备可以根据参考时域位置和参考信号传输的起始时域位置确定时间间隔；进而根据时间间隔生成参考信号，这样可以保证多个终端设备在插入第二时长的时间间隔之前，各自的参考信号正交。在此统一说明，以下不再赘述。

下面将结合图2至图4，以图2所示的多个终端设备40中的第一终端设备与网络设备进行交互为例，对本申请实施例提供的通信方法进行展开说明。
需要说明的是，本申请下述实施例中各个网元之间的消息名字或消息中各参数的名字等只是一个示例，具体实现中也可以是其他的名字，本申请实施例对此不作具体限定。
如图5所示，为本申请实施例提供的一种通信方法，该通信方法包括如下步骤：
S501、第一终端设备根据预配置的上行时频资源确定参考时域位置，其中，该参考时域位置与多个终端设备中的其他终端设备确定的参考时域位置相同。
也就是说，本申请实施例中，能够在相同的上行时频资源上传输上行数据的多个终端设备对应相同的参考时域位置。
一种可能的实现方式中，本申请实施例中，参考时域位置为预配置的上行时频资源所在的周期内，预配置的上行时频资源的起始时域位置前的一个时域位置。
示例性的，如图6所示，假设预配置的上行时频资源为上行时频资源1，则参考时域位置可以为预配置的上行时频资源1所在的周期内，预配置的上行时频资源1的起始时域位置与预配置的上行时频资源1所在的周期的起始位置之间的一个位置。
或者，示例性的，如图7所示，假设预配置的上行时频资源为上行时频资源1，则参考时域位置可以为预配置的上行时频资源所在的周期的起始位置。
另一种可能的实现方式中，本申请实施例中，参考时域位置为预配置的上行时频 资源的起始时域位置，如图8所示。
可选的，这里预配置的上行时频资源可以是周期性的，也可以是非周期性的，在此不作具体限定。
对于上述两种可能的实现方式：
可选的，第一终端设备根据预配置的上行时频资源确定参考时域位置，可以包括：第一终端设备接收来自网络设备的第一指示信息，第一指示信息用于指示参考时域位置相对于预配置的上行时频资源所在的周期的起始位置的第一偏移时长；第一终端设备根据第一指示信息和预配置的上行时频资源所在的周期的起始位置，确定参考时域位置。
示例性的，结合上述图6进行说明，第一指示信息可以用于指示参考时域位置相对于预配置的上行时频资源1所在的周期的起始位置的第一偏移时长P1，进而，第一终端设备根据第一指示信息和预配置的上行时频资源1所在的周期的起始位置，可以确定参考时域位置，如图9所示。
或者，可选的，第一终端设备根据预配置的上行时频资源确定参考时域位置，可以包括：第一终端设备接收来自网络设备的第二指示信息，第二指示信息用于指示预配置的上行时频资源的起始时域位置相对于参考时域位置的第二偏移时长；第一终端设备根据第二指示信息和预配置的上行时频资源的起始时域位置，确定参考时域位置。
示例性的，结合上述图7进行说明，第二指示信息可以用于指示预配置的上行时频资源1的起始时域位置相对于参考时域位置的第二偏移时长P2，进而，第一终端设备根据第二指示信息和预配置的上行时频资源2的起始时域位置，可以确定参考时域位置，如图10所示。
再一种可能的实现方式中，若预配置的上行时频资源为周期性资源，则可以每N个预配置的上行资源对应一个参考时域位置，该参考时域位置为每N个预配置的上行时频资源中的第一个预配置的上行时频资源所在的周期内，第一个预配置的上行时频资源的起始时域位置前的一个时域位置，N为大于1的正整数。
可选的，该实现方式中，终端设备也可以根据网络设备发送的指示信息确定参考时域位置，该指示信息用于指示每个参考时域位置相对于每N个预配置的上行时频资源中的第一个预配置的上行时频资源所在的周期的起始位置的第三偏移时长，或者，该指示信息用于指示每N个预配置的上行时频资源中的第一个预配置的上行时频资源的起始位置相对于每个参考时域位置的第四偏移时长，相关示例可参考上述图9或图10，在此不再赘述。
再一种可能的实现方式中，若预配置的上行时频资源为周期性资源，则可以每N个预配置的上行资源对应一个参考时域位置，该参考时域位置为每N个预配置的上行时频资源中的第一个预配置的上行时频资源的起始位置，N为大于1的正整数。
示例性的，假设N＝2，即每2个预配置的上行资源对应一个参考时域位置，则如图11所示，假设预配置的上行时频资源5在第5个周期内，预配置的上行时频资源6在第6个周期内，预配置的上行时频资源7在第7个周期内，预配置的上行时频资源8在第8个周期内，则预配置的上行时频资源5和预配置的上行时频资源6可以对应参考时域位置3，预配置的上行时频资源7和预配置的上行时频资源8可以对应参考 时域位置4。也就是说，假设步骤S501中的预配置的上行时频资源为图11中所示的预配置的上行时频资源8，则根据该预配置的上行时频资源8确定出的参考时域位置应该为图11所示的参考时域位置4，即预配置的上行时频资源7所在的周期内，预配置的上行时频资源7的起始时域位置前的一个时域位置；或者，假设步骤S501中的预配置的上行时频资源为图11中所示的预配置的上行时频资源5，则根据该预配置的上行时频资源5确定出的参考时域位置应该为图11所示的参考时域位置3，即预配置的上行时频资源5所在的周期内，预配置的上行时频资源5的起始时域位置前的一个时域位置。
需要说明的是，图11中示意出的参考时域位置为每N个预配置的上行时频资源中，第一个预配置的上行时频资源所在的周期内，第一个预配置的上行时频资源的起始时域位置与第一个预配置的上行时频资源所在的周期的起始位置之间的一个位置，当然，该参考时域位置也可以是每N个预配置的上行时频资源中，第一个预配置的上行时频资源所在的周期的起始位置；或者，该参考时域位置也可以是每N个预配置的上行时频资源中，第一个预配置的上行时频资源的起始位置，在此不再一一画图示意。
可选的，本申请实施例中，预配置的上行时频资源所在的周期的起始位置满足：
(起始位置对应的子帧号)mod(预配置的上行时频资源的周期/第一设定值)＝0，或者，(起始位置对应的帧号)mod(预配置的上行时频资源的周期/第二设定值)＝0；其中，mod()表示取余，第一设定值或第二设定值为正数。
其中，若通过预配置的上行时频资源所在的周期的起始位置对应的子帧号计算，示例性的，若预配置的上行时频资源的周期的单位为毫秒(ms)，则这里的第一设定值可以为1；或者，示例性的，若预配置的上行时频资源的周期的单位为(10ms)，则这里的第一设定值可以为10。
或者，若通过预配置的上行时频资源所在的周期的起始位置对应的帧号计算，示例性的，若预配置的上行时频资源的周期的单位为ms，则这里的第二设定值可以为10；或者，示例性的，若预配置的上行时频资源的周期的单位为10ms，则这里的第二设定值可以为1。
可选的，本申请实施例中，参考时域位置也可能和预配置的上行时频资源没有关系。比如，如图12所示，参考时域位置可以为一个绝对时域位置，该绝对时域位置可以是网络设备配置给终端设备的，也可以是提前预配置在终端设备上或者协议规定的，本申请实施例对此不作具体限定。
S502、第一终端设备将距离参考时域位置(第一时长*N+第二时长*(N-1))的时域位置确定为X个时间间隔的起始时域位置，N为1，2，3，4，…，X，其中，X个时间间隔均不用于发送上行数据，X为正整数。
也就是说，本申请实施例中，若X＝2，则第一终端设备将确定2个时间间隔的起始时域位置，其中，第1个时间间隔的起始时域位置与参考时域位置之间的距离为第一时长，第2个时间间隔的起始时域位置与参考时域位置之间的距离为第一时长*2+第二时长。当然，若X大于2，可以以此类推。
示例性的，本申请实施例中的第一时长为256ms的正整数倍，例如第一时长可以是256ms。
示例性的，本申请实施例中的第二时长为40ms的正整数倍，例如第二时长可以是40ms。
S503、第一终端设备将距离参考时域位置(第一时长*(M-1)+第二时长*(M-1))的时域位置确定为Y个第一时长的起始时域位置；其中，Y个第一时长中的至少一个第一时长对应的时域资源中的全部或部分为用于传输上行数据的第一时频资源中的时域资源，M为1，2，3，4，…，Y，Y＝X或者Y＝X+1。
也就是说，本申请实施例中，若X＝2，Y＝X，则第一终端设备将确定2个第一时长的起始时域位置，其中，第1个第一时长的起始时域位置与参考时域位置之间的距离为0，第2个第一时长的起始时域位置与参考时域位置之间的距离为第一时长+第二时长。当然，若X大于2，可以以此类推。
示例性的，假设第一时长为256ms，第二时长为40ms，X＝2，Y＝X，则2个第一时长的位置和2个时间间隔的插入位置的示意图可以如图13所示。
或者，本申请实施例中，若X＝2，Y＝X+1，则第一终端设备将确定3个第一时长的起始时域位置，其中，第1个第一时长的起始时域位置与参考时域位置之间的距离为0，第2个第一时长的起始时域位置与参考时域位置之间的距离为第一时长+第二时长，第3个第一时长的起始时域位置与参考时域位置之间的距离为(第一时长+第二时长)*2。当然，若X大于2，可以以此类推。
示例性的，假设第一时长为256ms，第二时长为40ms，X＝2，Y＝X+1，则3个第一时长的位置和2个时间间隔的插入位置的示意图可以如图14所示。
可选的，本申请实施例中，上行数据传输的起始位置可能为参考时域位置，也可能是参考时域位置之后的某一个位置。比如，上行数据传输的起始位置为Y个第一时长中第S个第一时长上，S为小于Y的正整数，本申请实施例对此不作具体限定。
此外，本申请实施例中，一方面，考虑到第一终端设备可能在参考时域位置之后的某个位置开始传输上行数据；另一方面，考虑到上行数据与随机接入信道(例如可以是物理随机接入信道(physical random access channel，NPRACH))碰撞将会推迟上行数据的传输，因此X个第一时长中的至少一个第一时长对应的时域资源的全部或部分为用于传输上行数据的第一时频资源中的时域资源。
示例性的，如图15所示，假设上行数据的总传输时长为512ms，上行数据在参考时域位置开始传输，则上行数据在第1个第一时长上传输256ms之后，第1个40ms的时间间隔将被插入；在1个40ms的时间间隔之后，上行数据在第2个第一时长上传输256ms之后，数据传输即可结束。可以看出，该示例中，X＝2，Y＝X，2个第一时长对应的时域资源的全部时域资源为用于传输上行数据的第一时频资源中的时域资源。
或者，示例性的，如图16所示，假设上行数据的总传输时长为300ms，上行数据在参考时域位置之后的第100ms开始传输，则上行数据在第1个第一时长上传输256-100＝156ms之后，第1个40ms的时间间隔将被插入；假设在距离参考时域位置256+40＝296ms的位置处，上行数据与NPRACH碰撞，NPRACH需要传输256ms，则此时第2个第一时长将用于传输NPRACH，在第2个第一时长结束之后，第2个40ms的时间间隔将被插入。在第2个40ms的时间间隔结束之后，若上行数据在第3个第 一时长的起始时域位置和其他NPRACH没有碰撞，则第3个第一时长可以用于传输上行数据。由于上行数据的总传输时长为300ms，在第1个第一时长上已经传输156ms，因此在第3个第一时长上传输300-156＝144ms之后传输即可结束。可以看出，该示例中，X＝2，Y＝X+1，3个第一时长中的第1个第一时长和第3个第一时长对应的时域资源中的部分时域资源为用于传输上行数据的第一时频资源中的时域资源。
或者，示例性的，如图17所示，假设上行数据的总传输时长为200ms，上行数据在距离参考时域位置(256+40+100)ms处开始传输，即上行数据传输的起始位置为距离第2个第一时长的起始位置100ms处，则假设上行数据开始传输100ms之后，上行数据与NPRACH碰撞，NPRACH需要传输156ms，则NPRACH传输的结束位置在距离第3个第一时长的起始位置60ms处。此时，由于上行数据已经在第2个第一时长上传输100ms，因此上行数据继续传输100ms传输即可结束。可以看出，该示例中，X＝2，Y＝X+1，3个第一时长中的第2个第一时长和第3个第一时长对应的时域资源中的部分时域资源为用于传输上行数据的第一时频资源中的时域资源。
需要说明的是，本申请实施例中，在存在预配置的上行时频资源的情况下，预配置的上行时频资源中可以包括该第一时频资源，也可以不包括该第一时频资源，在此不作具体限定。
可选的，本申请实施例中，步骤S502与步骤S503之间没有必然的执行先后顺序，可以是先执行步骤S502，再执行步骤S503；也可以是先执行步骤S503，再执行步骤S502；还可以是同时执行步骤S502与步骤S503，本申请实施例对此不作具体限定。
S504、网络设备根据预配置的上行时频资源确定参考时域位置。
S505、网络设备将距离参考时域位置(第一时长*N+第二时长*(N-1))的时域位置确定为X个时间间隔的起始时域位置，N为1，2，3，4，…，X，其中，X个时间间隔均不用于发送上行数据，X为正整数。
S506、网络设备将距离参考时域位置(第一时长*(M-1)+第二时长*(M-1))的时域位置确定为Y个第一时长的起始时域位置；其中，Y个第一时长中的至少一个第一时长对应的时域资源中的全部或部分为用于传输上行数据的第一时频资源中的时域资源，M为1，2，3，4，…，Y，Y＝X或者Y＝X+1。
其中，步骤S504-S506的相关描述可参考上述步骤S501-S503，在此不再赘述。
可选的，本申请实施例中，步骤S505与步骤S506之间没有必然的执行先后顺序，可以是先执行步骤S505，再执行步骤S506；也可以是先执行步骤S506，再执行步骤S505；还可以是同时执行步骤S505与步骤S506，本申请实施例对此不作具体限定。
可选的，本申请实施例中，步骤S501-S503与步骤S504-S506之间没有必然的执行先后顺序，可以是先执行步骤S501-S503，再执行步骤S504-S506；也可以是先执行步骤S504-S506，再执行步骤S501-S503；还可以是同时执行步骤S501-S503与步骤S504-S506，本申请实施例对此不作具体限定。
S507、第一终端设备在第一时频资源上向网络设备发送上行数据。网络设备在第一时频资源上接收来自第一终端设备的上行数据。
当然，本申请实施例中，第一终端设备在第一时频资源上向网络设备发送上行数据的同时，需要在第一时频资源上向网络设备发送用于解调该上行数据的参考信号(如 DMRS)，具体可参考现有的实现方式，在此不予赘述。
基于本申请实施例提供的通信方法，由于同一小区的能够在相同上行时频资源上传输上行数据的多个终端设备对应相同的参考时域位置，并且距离参考时域位置(第一时长*N+第二时长*(N-1))的时域位置为X个时间间隔的起始时域位置，因此对于同一小区的能够在相同上行时频资源上传输上行数据的多个终端设备来说，即使多个终端设备发送上行数据的起始位置不一样，也可以保证插入的第二时长的时间间隔的起始位置和结束位置均对齐，进而若多个终端设备在插入第二时长的时间间隔之前，各自的参考信号正交，也可以保证多个终端设备在插入第二时长的时间间隔之后，各自的参考信号正交。
示例性的，以shared resource的子载波间隔为15kHz，一个RU＝8ms为例，如图18所示，假设同一小区的UE1和UE2在shared resource上传输上行数据时，UE1发送上行数据的起始位置与UE2发送上行数据的起始位置不同，UE1插入40ms(对应5个RU)gap之前，UE1和UE2对应的Hadamard序列正交，UE1和UE2对应的Gold序列相同，因此UE1对应的DMRS和UE2对应的DMRS正交。在UE1插入40ms gap的位置，虽然UE2传输的时长＜256ms，此时UE2也在相同的位置插入40ms gap。这样，在40ms gap结束之后的第一个slot上，UE1对应的DMRS的生成公式(1)和公式(2)中的n的取值为16m+16，UE2对应的DMRS的生成公式(1)和公式(2)中的n的取值为16m+16，则根据上述Hadamard序列和Gold序列的描述可知，此时，RU边界对齐，在相同的时频资源上，UE1对应的Hadamard序列和UE2对应的Hadamard序列仍然正交，且UE1对应的Gold序列和UE2对应的Gold序列相同，从而可以保证在UE1插入40ms gap之后，UE1对应的DMRS和UE2对应的DMRS正交。
需要说明的是，若上述示例中UE1发送上行数据的起始位置不是参考时域位置，则在插入的第一个40ms gap的起始位置处，UE1传输的时长也是小于256ms。即第一个40ms gap的起始时域位置距离参考时域位置256ms，不依赖于UE1传输的时长或者UE2传输的时长是否为256ms。
其中，上述步骤S501至S507中的网络设备的动作可以由图3所示的网络设备30中的处理器301调用存储器302中存储的应用程序代码以指令该网络设备执行，上述步骤S501至S507中的第一终端设备的动作可以由图3所示的终端设备40中的处理器401调用存储器402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。
可以理解的是，以上各个实施例中，由第一终端设备实现的方法和/或步骤，也可以由可用于第一终端设备的部件(例如芯片或者电路)实现，由网络设备实现的方法和/或步骤，也可以由可用于网络设备的部件实现。
