近年来，以车联网为代表的智能交通技术得到了飞速的发展。在第三代合作伙伴计划(3rd generation partnership project，3GPP)也进行了类似的研究，产生了车到一切(vehicle-to-everything，V2X)技术。其中，V2X技术例如包括车辆到车辆(vehicle-to-vehicle，V2V)通信技术，车辆到人(vehicle-to-pedestrian，V2P)通信技术，车辆到道路设施(vehicle-to-infrastructure，V2I)通信技术等，当然还可能包括其他的通信技术。例如，在3GPP的长期演进(long term evolution，LTE)系统中，已经完成了对版本(Rel)-14的标准化研究，并且正在进行Rel-15的标准化工作。
另一方面，3GPP基于对第五代(5th generation，5G)展开研究的标准已经发布，5G Rel-15的第一个版本支持长期演进新的无线接入技术的双连接(E-UTRAN New Radio–Dual Connectivity，EN-DC)的网络架构。在EN-DC的网络架构下，LTE基站演进型节点B(evolved node B，eNB)作为主载波，新无线(new radio，NR)中的基站(gNB)作为辅载波为终端提供服务。也就是说，eNB或gNB可以作为终端设备的同步源，此外，全球导航卫星系统(global navigation satellite system，GNSS)也可以作为终端设备的同步源。传统方案中，终端能够根据从同步源获取的时间确定出终端设备的帧号和子帧号，随着终端设备对时间的精确度要求越来越高，终端设备在同步到上述同步源时如何提高终端设备的定时精度亟待解决。

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。
需要说明的是，在本申请实施例中，在应用层可以运行多个应用程序，此情况下，执行本申请实施例的通信方法的应用程序与用于控制接收端设备完成所接收到的数据所对应的动作的应用程序可以是不同的应用程序。
图1是本申请实施例的应用场景的示意图。如图1所示，该应用场景可以是车联网场景，该车联网场景包括一个或多个全球导航卫星系统(global navigation satellite system，GNSS)，一个或多个LTE基站设备(eNB)，一个或多个NR基站设备(gNB)，一个或多个路侧单元(roadside unit，RSU)，以及一个或多个车载设备(例如，UE1、UE2和UE3)。其中，GNSS可以用于为各个网元提供定位信息，eNB可以与各个车载设备和/或RSU进行通信，gNB也可以与各个车载设备和/或RSU进行通信，RSU可以与各个车站设备和/或eNB进行通信，车载设备可以与GNSS、eNB、gNB、RSU，以及与其他车载设备中的至少一项进行通信。
需要说明的是，本申请可以应用于包括eNB和gNB的场景中，也可以应用于不包括eNB和/或gNB的场景中。具体地，在存在eNB和/或gNB的情况下，为网络覆盖场景；在不存在eNB和gNB的情况下，为无网络覆盖的场景。
还需要说明的是，RSU从功能上可以看作是一个车载设备，也可以看作是一个eNB设备，本申请对此不进行限定。
还需要说明的是，UE与UE之间的链路，在D2D中可以称为“D2D链路”，也可以称为“边链路或侧行链路(sidelink)”，还可以称为PC5链路，或者在车联网中可以称为车到车(vehicle to vehicle，V2V)链路，或车到人(vehicle to pedestrian，V2P)链路，车到基础设施(vehicle to infrastructure，V2I)链路，为方便描述下述实施例以“侧行链路”为例进行说明，但本申请并不限于此。此外，网络设备(例如，gNB、eNB或RSU)与UE之间的链路可以称为蜂窝链路。
应理解，图1所示的场景中的各个设备之间的通信可以是使用蜂窝链路的频谱，也可以是使用5.9GHz附近的智能交通频谱，本申请对此不进行限定。
还需要说明的是，本申请实施例中进行D2D通信的两个终端可以同步到同一类同步源，也可以同步到不同类的同步源中。例如，UE3同步到gNB，UE2同步到eNB，且UE2和UE3之间进行D2D通信；或者UE1同步到eNB，UE2同步到eNB，且UE1和UE2之 间进行D2D通信；或者UE3同步到gNB，UE2同步到eNB，UE2和UE3之间进行D2D通信。
此外，在LTE系统中，子载波间隔为固定值，而在5G标准中支持多种子载波间隔的类型，例如，子载波间隔为15kHz，30kHz，60kHz，120kHz，240kHz和480kHz等。因此，在进行D2D通信的两个终端同步到两个不同类的gNB时，可以是两个gNB的子载波间隔不同。
其中，在基于正交频分复用(Orthogonal Frequency Duplex Multiplexing，OFDM)的系统中，某个子带中的子载波间隔和该子带对应的OFDM符号的长度成反比，即子载波间隔越大，OFDM符号的长度越短。例如，如图2以子载波间隔分别为15kHz和60kHz为例，示出了子载波间隔分别为15kHz和60kHz与OFDM符号长度的对应关系。如图2所示，OFDM系统使用快速傅里叶变换(Fast Fourier Transformation，FFT)将一个时域上的OFDM符号变换到频域上对应的子载波，频域上的子载波经过FFT的逆变换即快速傅里叶逆变换(Inverse Fast Fourier Transformation，IFFT)变化成时域上的一个OFDM符号。在基于OFDM的系统中，子载波间隔和OFDM符号的长度成反比，即子载波间隔的类型为15kHz时对应的一个OFDM符号的时间长度是子载波间隔的类型为60kHz时对应的一个OFDM符号的时间长度的4倍。在一个服务小区，数据的发送是基于传输时间间隔(transmission time interval，TTI)的，也就是一次数据发送，时间长度为1个TTI。具体地，一个TTI可以是一个子帧1ms，或者1个slot。slot可以是一个相对单位，即仅定义slot包含的OFDM符号个数。例如，如图2所示，一个slot包含7个OFDM符号，当子载波间隔的类型为15kHz时，一个slot的绝对时间长度为0.5ms，当子载波间隔的类型为60kHz时，一个slot的绝对时间长度为0.125ms。
传统方案中，终端能够根据从同步源获取的时间确定出终端设备的帧号和子帧号，随着终端设备对时间的精确度要求越来越高，终端设备在同步到上述同步源时如何提高终端设备的定时精度亟待解决。
图3示出了本申请实施例的确定传输资源的方法的示意性流程图。
301，第一终端设备从同步源获取第一时间。相应地，同步源发送该第一时间。
可选地，该同步源可以是eNB，gNB，或GNSS中的任意一项。
具体地，第一终端设备与eNB通信占用的资源的子载波间隔通常固定为15kHz，第一终端设备与gNB通信占用的资源的子载波间隔通常为15*2 μkHz，其中μ的取值为0、1、2、3或4，即对应的子载波间隔分别为15kHz、30kHz、60kHz、120kHz和240kHz。为描述方便，下述实施例μ的取可以描述为对应于子载波间隔，例如，对应于子载波间隔为15kHz的μ的取值为0，对应于子载波间隔为30kHz的μ的取值为1，60kHz的μ的取值为2、120kHz的μ的取值为3和240kHz的μ的取值为4。
在本申请实施例中，有关时隙的概念是指，特定子载波间隔下的一次传输所占用的时长。可以是1ms，0.5ms，0.25ms，0.125ms，或0.0625ms，或其它长度值。其占用的符号可以是14个，12个，7个，6个，4个，3个，或2个，或其它符号数等。例如，对于LTE系统而言，一个时隙的长度为0.5ms，一个子帧的长度为1ms。在NR系统中，不同的子载波间隔下一个时隙的长度不同，可以简单地认为是1ms除以2的整数倍。另外，NR系统也支持迷你时隙(mini-slot)的传输，即，只是用部分符号来做的时隙的传输。
当UE的同步源是网络设备时，UE从网络设备获取第一时间。获取到的第一时间的精度与UE的实现以及网络设备发送信号的带宽有关。通常，UE可以获取网络设备发送信号的无线帧号，子帧号或时隙号。如果要获取更高精度的第一时间的信息，还可以得到符号的起止位置，循环前缀(cyclic prefix，CP)的起止位置，或者采样点级的时间精度的位置。在UE在基带宽信号的解调前，UE要对接收到的信号进行采样，对多载波系统，采样率Fs通常为子载波间隔与快速傅里叶变换(Fast Fourier Transform，FFT)点数整数倍。例如：对15kHz的子载波间隔的系统，FFT点数为2048时，采样率为30.72M的整数倍。例如，当Fs＝30.72M时，每个采样点对应的时间精度Ts＝1/Fs＝0.0326us。因此，当UE同步到网络设备时，也可以获高精度的第一时间信息。
当UE的同步源是是卫星时，UE从卫星设备获取第一时间。与GNSS获取的第一时间的时间精度是卫星提供的信息为基础获得的，通常与卫星的体制和卫星信号的接收机有关。例如，可以达到几十纳秒的定时精确度。这个时间精度，对于以毫秒或微秒级的无线通信系统而言是足够的。
可选地，在同步源为卫星的情况下，该第一时间为UTC时间。
可选地，在同步源为网络设备的情况下，该第一时间为当前网络的时间。
具体地，网络的时间可以是无线帧、子帧、时隙或微时隙、符号所对应的时间。
具体地，在同步源为该网络设备的情况下，该第一时间为该网络设备覆盖范围内的网络的时间。其中，该网络设备可以是eNB，也可以是gNB。
302，该第一终端设备根据该第一时间和侧行链路的子载波间隔，确定该侧行链路的时隙号，该侧行链路用于该第一终端设备和第二终端设备传输侧行信息。
具体地，侧行链路为终端设备之间通信使用的链路，侧行链路的子载波间隔可以是侧行链路占用的资源的子载波间隔，第一终端设备可以根据该第一时间和该侧行链路的子载波间隔确定该侧行链路的时隙号。
需要说明的是，一个终端通过侧行链路进行通信的对端可以是一个终端，也可以是多个终端；或者多个终端通过侧行链路与一个终端进行通信，即步骤302中的终端为该多个终端中的任意一个，本申请对此不进行限定。
可选地，步骤302具体可以是第一时间、该侧行链路的子载波间隔和该侧行链路的时隙号满足：slot＝floor(f1(t)·g(μ))mode h(μ)，其中slot为所述侧行链路的时隙号，f1(t)表示第一时间t的函数，μ的取值对应于所述侧行链路的子载波间隔，g(μ)和h(μ)为μ的函数，floor()表示向下取整，mode表示取余数，且μ为正整数，t≥0。
具体地，floor()表示向下取整，例如，floor(0.5)＝0,floor(3.1)＝3,floor(5.9)＝5。mode表示取余数，例如，3mode 10＝3，30mode 10＝0，13mode 10＝3。f1(t)表示第一时间t的函数，例如，f1(t)＝t，g(μ)可以表示一个时隙的绝对时长，例如，g(μ)＝2 μ，h(μ)可以表示一个子帧包括的时隙数目，例如，h(μ)＝2 μ。也就是说，slot＝floor(t·2 μ)mode 2 μ。
可选地，步骤302具体可以是第一时间、该侧行链路的子载波间隔和该侧行链路的时隙号满足：slot＝(f1(t)·g(μ))mode h(μ)，其中slot为所述侧行链路的时隙号，f1(t)表示第一时间t的函数，μ的取值对应于所述侧行链路的子载波间隔，g(μ)和h(μ)为μ的函数，mode表示取余数，且μ为正整数，t≥0，。
可选的，h(μ)与g(μ)可以相同或不同。
需要说明的是，本申请中所有公式在计算中应该统一时间单位，例如上述公式的时间单位可以是ms。
可选地，步骤302更具体可以是根据该第一时间、该同步源的参考时间和该侧行链路的子载波间隔确定该侧行链路的时隙号。
具体地，第一终端设备需要考虑同步源的当前时间以及该同步源的参考时间，再结合侧行链路的子载波间隔确定该侧行链路的时隙号。在同步源为卫星的情况下，同步源的参考时间可以是UTC格林威治时间的1900年1月1号的00:00:00。在同步源为网络设备的情况下，该同步源的参考时间可以是网络当前的时间所在的无线帧的第一个无线帧的帧头的时间。可选地，同步源的参考时间是可以通过网络配置或预配置给第一终端设备的，在未被配置时，其取值为零。

还需要说明的是，该侧行链路的定时与该第一链路的定时可以是对齐的，也可以是存在时间偏差，例如，如图7所示，15kHz的子载波间隔对应的时隙号n的起始位置与30kHz的子载波间隔对应的时隙号m的起始位置存在时间偏移。
可选地，步骤602具体可以是根据该时间间隔、该第一时隙号、该第一子载波间隔和该第二子载波间隔确定该第二时隙号。
具体地，第一终端设备可以获知该第一链路的第一子载波间隔，以及侧行链路的第二子载波间隔，进而可以根据该第一子载波间隔、第二子载波间隔、第一时隙号、以及时间间隔，确定该第二时隙号。
可选地，该时间间隔、该第一时隙号、该第一子载波间隔、该第二子载波间隔和该第二时隙号可以满足如下公式：
Figure PCTCN2019115029-appb-000003
其中，slot为该第二时隙号，n为第一时隙号，μ s的取值对应于该第二子载波间隔，μ u的取值对应于该第一子载波间隔，K2为时间间隔，且n、μ s、μ u均为正整数，K2>0。
例如，以n＝2，μ u＝2，μ s＝1，K2＝1为例进行说明，则slot＝2。
可选地，步骤602具体还可以是根据该时间间隔、该第一时隙号、该第一子载波间隔、时间偏移值和该第二子载波间隔确定该第二时隙号。
具体地，第一终端设备可以获知该第一链路的第一子载波间隔，侧行链路的第二子载波间隔，以及时间偏移值，进而可以根据该第一子载波间隔、第二子载波间隔、第一时隙号、时间偏移值以及时间间隔，确定该第二时隙号。

Figure PCTCN2019115029-appb-000004
其中，slot为所述第二时隙号，n为所述第一时隙号，μ s的取值对应于所述第二子载波间隔，μ u的取值对应于所述第一子载波间隔，K2为所述时间间隔，offset为所述时间偏移值，且n、μ s、μ u均为正整数，K2>0，offset≥0。
可选地，步骤602具体还可以是根据该第一时隙号，确定该目标时隙，进而根据该目标时隙与该时间间隔确定该第二时隙号。
具体地，由于该第一终端设备接收下行控制信息占用的时域资源可以是1个或多个时隙，这样该第一终端设备可以从该一个或多个时隙中选择一个作为目标时隙(例如，以起始长度指示值(start length indication value，SLIV)为例进行说明)，从目标时隙开始计算，将经过指示信息指示的时间间隔后的时域位置所在时隙的时隙号确定为该第二时隙号。
例如，例如，如图7所示，第一链路的子载波间隔为15kHz，侧行链路的子载波间隔为30kHz，第一终端在第n时隙发送下行信息，该第n时隙与第m时隙、第m+1时隙和第m+2时隙重叠，该第一终端设备需要确定以第m时隙、第m+1时隙和第m+2时隙中的哪一个时隙的起始位置作为目标时隙，并根据该目标时隙的时隙号和时间间隔k2，可以确定出第二时隙号为m+2。若以第m时隙为目标时隙，则从该第m时隙的起始位置开始经过时间间隔在第m+3时隙上发送上行信息(例如，物理侧行链路共享信道(pysical sidelink share channel，PSSCH))；若以第m+1时隙为目标时隙，则从该第m+1时隙的起始位置开始经过时间间隔在第m+4时隙上发送上行信息。
再例如，如图8所示，第一链路的子载波间隔为60kHz，侧行链路的子载波间隔为30kHz，则网络设备在n+1时隙发送下行信息，若第一终端设备以m时隙作为目标时隙，则在m+1时隙上发送上行信息；若第一终端设备以m+1时隙作为目标时隙，则在m+2时隙上发送上行信息。
应理解，网络设备发送的下行信息可以是下行控制信息(down control information，DCI)，也可以是无线资源控制(radio resource control，RRC)信令。
还应理解，这里的目标时隙，是指该指示信息在侧行链路上有效或起指示作用的时隙。该目标时隙也可以称为“生效时隙”。
可选的，第一终端设备根据该第一时隙号，确定该指示信息在该侧行链路上的目标时隙具体可以是该第一终端设备根据该第一时隙号和预设条件，确定该目标时隙。
具体地，该第一时隙号所在的时隙与侧行链路占用的资源中的至少两个时隙重叠的情况下，该第一终端设备可以根据预设条件和第一时隙号，从该至少两个时隙中选择其中一个时隙作为目标时隙，这样使得该第一终端设备可以与侧行链路的对端设备采用统一的目标时隙进行通信，从而提高了通信质量。
可选地，该预设条件可以是固定将该至少两个时隙中的某一个作为目标时隙。例如，可以将该至少两个时隙中的第一个时隙作为目标时隙，也可以将该至少两个时隙中的最后一个作为目标时隙，或者将该至少两个时隙中第一个时隙中的下一个时隙作为目标时隙。
可选地，该预设条件的具体内容也可以是灵活调节，具体地，该第一终端设备可以根据该第一子载波间隔与该第二子载波间隔的大小关系确定该预设条件。例如，该第一子载波间隔大于或等于该第二子载波间隔的情况下，该预设条件为以第一个时隙作为目标时隙；或者该第一子载波小于该第二子载波间隔的情况下，该预设条件为以第一个时隙之后的下一个时隙作为目标时隙；或者，第一子载波间隔与第二子载波间隔的其他大小关系与上述预设条件中的任一项可能的内容具有对应关系，本申请对此不进行限定。
可选地，该预设条件的具体内容也可以是灵活调节，具体地，该第一终端设备可以根 据该第一时隙号所在的时隙与该至少两个时隙中每个时隙的重叠区域的大小确定该预设条件。例如，第一终端设备将第一时隙所在的时隙与该至少两个时隙中重叠区域最大的时隙作为该目标时隙，或者将重叠区域最小的时隙作为该目标时隙，或者还可以将重叠区域的大小进行排序，设定排序中的某一个序号的时隙作为该目标时隙。
可选地，该预设条件还可以是由该第一时隙号所在的时隙与该至少两个时隙重叠区域的位置确定的。例如，将该两个时隙中整个时隙的前面部分区域重叠的时隙作为目标时隙，或者将整个时隙的后面部分区域重叠的时隙作为目标时隙。
可选地，在该第一时隙号所在的时隙与该侧行链路占用的资源中的至少两个时隙重叠的情况下，该指示信息还用于指示将该至少两个时隙中的第一时隙确定为该指示信息的目标时隙。
具体地，在该第一时隙号所在的时隙与该侧行链路占用的资源中的至少两个时隙重叠的情况下，该指示信息还可以携带指示该至少两个时隙中的目标时隙的信息，这样第一终端设备根据该指示信息就可以确定出目标时隙，这样使得该第一终端设备可以与侧行链路的对端设备采用统一的目标时隙进行通信，从而提高了通信质量。
603，所述第一终端设备在所述第二时隙号对应的时隙上向所述第二终端设备发送所述侧行信息和/或从所述第二终端设备接收所述侧行信息。相应地，第二终端设备接收和/或发送信号。
具体地，该第二终端设备可以是用于做单播通信的特定的某一个终端设备，或者，该第二终端设备为用于做组播或多播通信的多个终端设备，或者该第二终端设备为用于做广播通信的多个或不确定接收对象的终端。例如，第一终端设备通过侧行链路通信的对端可以为一个或多个终端设备，该第二终端设备为该多个终端设备中的一个，或该多个终端设备中的部分终端设备，或者该多个终端设备中的全部终端设备。也就是说，本申请实施例中，第一终端设备在与网络设备通信的第一链路的子载波间隔与侧行链路的子载波间隔不同的情况下，能够根据接收到的用于指示时间间隔的指示信息的第一时隙号和该时间间隔确定出第二时隙号，进而在第二时隙号对应的时隙上与其他终端设备进行通信，这样提高了子载波间隔不同的跨载波调度的准确性，或者说降低了收发机之间的不一致问题，从而提高了通信质量。
