具体实施方式
为了解决基站如何通过relay UE向remote UE发送调度信息的问题，本申请实施例基于图1所示的通信系统，提供一种时域资源指示方法。如图1所示，该通信系统至少包括网络设备和两个电子设备。该通信系统中的两个电子设备可以直接进行通信的终端设备且这两个电子设备中至少有一个可以与网络设备进行通信，从而使该通信系统中的电子设备均可以通过该电子设备与网络设备进行通信。其中，能够与网络设备进行通信的电子设备可以是中继节点(Relay Node，RN)、基站、终端设备等，与该电子设备连接的电子设备可以为终端设备等。例如，两个可以直接进行通信的电子设备可以是两个用于D2D通信的终端设备，该用于D2D通信的终端设备也可以与网络设备进行蜂窝通信。需要说明的是，两个可以直接进行通信的终端设备也可以不是使用D2D通信技术的终端设备，例如，可以是采用蓝牙或者WIFI技术的终端设备，也可以是未来通信技术中其他可以使终端设备之间直接通信的技术，在本申请实施例中不作限制。
当然，两个可以直接进行通信的电子设备也可以分别为RN和终端设备，终端设备通过RN与网络设备进行通信。在本申请实施例中，不对图1所示的通信系统中的两个电子设备的类型进行限制。在下面的描述中，将以该通信系统中的两个电子设备为用于D2D通信的终端设备为例进行说明，例如该两个电子设备可以为终端设备1以及终端设备2，其中，终端设备1通过终端设备2连接到网络设备，或者终端设备1通过终端设备2与网络设备通信。
在本申请实施例中，所述通信系统可以为各种无线接入技术(Radio Access Technology，RAT)系统，例如新无线(New Radio，NR)系统、无线保真(wifi)、全球微波互联接入(Worldwide Interoperability for Microwave Access，WiMAX)、全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、第三代合作伙伴计划(The 3rd Generation Partnership Project，3GPP)相关的蜂窝系统、第四代移动通信技术(4th Generation,4G)网络或者第五代移动通信技术(5th generation，5G)网络等。
此外，该方法还可以适用于面向未来的通信技术，本申请实施例描述的系统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，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。
本申请实施例中所涉及的网络设备，可以是基站(Base Station，BS)，可以是中继(Relay Nodes，RN)设备，也可以是指接入网中在空中接口上通过一个或多个小区与无线终端设备通信的设备。该网络设备可用于将收到的空中帧与IP分组进行相互转换，作为终端设备与接入网的其余部分之间的路由器，其中，接入网的其余部分可包括IP网络。该网络设备还可协调对空中接口的属性管理。若该网络设备为基站，该基站可以是包括长期演进(Long  Term Evolution，LTE)系统或演进的LTE系统(LTE-Advanced，LTE-A)中的演进型基站(NodeB或Evolved Node B或evolutional Node B)，或者也可以包括5G系统中的下一代节点B(next generation node B，gNB)，本申请实施例并不限定。
在本申请实施例中所涉及的终端设备，可以包括向用户提供语音和/或数据连通性的设备，例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的处理设备。该UE可以经无线接入网(Radio Access Network，RAN)与核心网进行通信，与RAN交换语音和/或数据。该终端设备可以包括用户设备(User Equipment，UE)、无线终端设备、移动终端设备、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point，AP)、远程终端设备(Remote Terminal)、接入终端设备(Access Terminal)、用户终端设备(User Terminal)、用户代理(User Agent)、或用户装备(User Device)等。例如，可以包括移动电话(或称为“蜂窝”电话)，具有移动终端设备的计算机，便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，智能穿戴式设备等。例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)、智能手表、智能头盔、智能眼镜、智能手环、等设备。还包括受限设备，例如功耗较低的设备，或存储能力有限的设备，或计算能力有限的设备等。例如包括条码、射频识别(RFID)、传感器、全球定位系统(GPS)、激光扫描器等信息传感设备。
需要说明的是，图1所示的通信系统中所包含的网络设备和终端设备的数量和类型仅仅是一种例举，本申请实施例也并不限制于此。例如，还可以包含更多的网络设备，或者与更多与网络设备进行通信蜂窝的终端设备，或者更多可以直接通信的终端设备，例如更多进行D2D通信的终端设备，为简明描述，不在附图中一一描述。此外，在图1所示的通信系统中，尽管示出了网络设备及终端设备，但所述通信系统中可以并不限于包括网络设备和终端设备，例如，还可以包括核心网设备或用于承载虚拟化网络功能的设备等，这些对于本领域普通技术人员而言是显而易见的，在此不一一详述。
另外，本申请实施例中的术语“系统”和“网络”可被互换使用。“多个”是指两个或两个以上，鉴于此，本发明实施例中也可以将“多个”理解为“至少两个”。“和/或”，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。另外，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。
在现有技术中，如图1所示的通信系统中，当终端设备1需要与终端设备2直接通信时，可以由网络设备通过物理下行控制信道(Physical Downlink Control Channel，PDCCH)向终端设备1发送下行控制信息(Downlink Control Information，DCI)，指示其与终端设备2直接进行通信的资源位置，然后，终端设备1在网络设备指示的资源位置上发送或接收数据。
由图1可知，终端设备1与网络设备之间的通信链路可以有两条。第一条为终端设备1直接与网络设备连接时的链路，标记为L1；第二条为终端设备1通过终端设备2与网络设备连接时的链路，标记为L2，此时，终端设备1称为remote UE，终端设备2称为relay UE，则remote UE通过relay UE连接到网络设备，或者remote UE通过relay UE与网络设备通信， 或者remote UE与网络设备之间的数据可以通过relay UE转发的，或者remote UE与relay UE相链接(remote UE is linked to remote UE,remote UE and relay UE are associated)，或者remote UE与relay UE相关联(remote UE and relay UE are associated)。这样，当网络设备向remote UE分配资源时，例如，网络设备向remote UE分配remote UE与relay UE之间的侧行链路(Sidelink，SL)资源，或者网络设备向remote UE分配上行链路(Uplink，UL)资源，则可以通过relay UE将资源指示给remote UE，remote UE在接收到指示信息后，则根据该指示信息分别确认时域资源和频域资源位置，完成资源的分配过程。
由于现有技术中当网络设备进行资源分配时，采用的是网络设备直接进行指示的方法，该方法已无法适用在网络设备通过relay UE将分配的资源指示给remote UE的情况，鉴于此，本申请实施例提供一种资源指示方法。通常来讲，资源位置包括时域资源位置和频域资源位置，在本申请实施例中只涉及网络设备通过relay UE将分配的时域资源指示给remote UE的情况。
在本申请实施例提供的一种时域资源指示方法中，第一设备根据在第一时域位置接收的由网络设备发送的第一调度信息，确定出向第二设备发送第二调度信息的第二时域位置或第二调度信息的内容，从而使第二设备在接收到第二调度信息后，则根据该第二调度信息，确定网络设备为其分配的资源的时域位置，可以实现通过第一设备转发网络设备对第二设备的调度信令的过程。
下面结合附图介绍本申请实施例提供的技术方案，在下面的介绍过程中，以将本申请提供的技术方案应用在图1所示的应用场景中为例，且以网络设备为基站，第一设备为终端设备2，第二设备为终端设备1为例。
请参考图2，为本申请一实施例提供的一种时域资源指示方法，该方法的流程描述如下。
步骤21：基站在第一时域位置向终端设备2发送第一调度信息，其中，所述第一调度信息包含第一指示信息，所述第一指示信息用于指示第一间隔。
在具体实施过程中，基站可以是在第一时域位置之前，接收到由终端设备1发送的资源请求或者由终端设备2转发的的资源请求后，在第一时域位置时向终端设备1反馈调度信息，或者基站在第一时域位置时主动发起给终端设备1分配时域资源的业务，然后基站根据资源的使用情况给终端设备1分配资源。第一时域位置可以为一个具体的时刻，例如第10s，也可以是以时间调度单位为单位进行表示，例如第n个时间调度单位所在的时域位置。在本申请实施例中，时间调度单位可以为帧、子帧、时隙、小时隙(mini-slot)、以及正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号中的任意一种。为统一描述，在本申请实施例中，将各个时域位置以子帧为单位进行表示，例如，第一时域位置为子帧n，基站在子帧n接收到由终端设备1发送的资源请求，则基站根据终端设备1发送链路资源的使用情况，确定分配给终端设备1的资源的时域位置。例如，基站确定子帧n+1到子帧n+T1-1对应的时域资源均已被占用，而子帧n+T1上有空闲资源，则基站可以将子帧n+T1所占用的时域资源分配给终端设备1，也可以将子帧n+T1至子帧n+T1+2对应的时域资源分配给终端设备1，也可以将子帧n+T1、子帧n+T1+2以及子帧n+T1+4对应的时域资源分配给终端设备1，在本申请实施例中，基站分配给终端设备1的时域资源可以为一个子帧，也可以为多个连续的子帧，也可以是多个不连续的子帧，在此不作限制。
当基站确定分配给终端设备1的资源的时域位置后，基站则可以根据分配给终端设备1 的资源的时域位置和第一时域位置确定第一间隔。第一间隔可以是一个目标时域位置与第一时域位置的间隔，该目标时域位置用于使终端设备1或终端设备2确定该资源的时域位置，该目标时域位置与该资源的时域位置可以相同，也可以不完全相同，第一间隔的含义具体可以有如下几种情况：
第一种情况，该资源可以是多个连续的子帧，则该目标时域位置可以是该资源的时域位置的起始位置，则第一间隔可以是该资源的起始时域位置与第一时域位置的间隔。例如，第一时域位置为子帧n，基站确定终端设备1分配的时域资源子帧n+T1至子帧n+T1+2，则第一间隔指示的间隔可以为T1个子帧。
第二种情况，该目标时域位置可以是该资源的时域位置，也可以是与该资源有一定间隔的位置，例如，该资源为某一个子帧，则该目标时域位置可以距离该子帧前N个子帧对应的位置，则该第一间隔可以为第一时域位置与该资源的时域位置的间隔与该N个子帧的差值。当然，该N个子帧可以在第一指示信息中指示，或者预先与终端设备1及终端设备2约定好。
第三种情况，该目标时域位置可以是该资源的特定位置，例如，该目标时域位置可以是该资源的中点位置，则第一间隔为该中点位置与第一时域位置之间的间隔。在这种情况下，假定第一时域位置为子帧n，基站确定终端设备1分配的时域资源子帧n+T1至子帧n+T1+2，则第一间隔可以为T1+1个子帧。在这种情况下，基站、终端设备1以及终端设备2之间可以预先约定好该资源的特定位置分别与该资源的起始位置及结束位置的间隔，例如，预先约定该特定位置为该资源的中点位置，且距离该资源的起始位置及结束位置的间隔均为1个子帧，这样，当终端设备1确定该特定位置后，则默认在该特定位置前1个子帧至该特定位置后1个子帧所占用的时域资源为基站为其分配的资源对应的时域位置。
第四种情况，该目标时域位置可以是用于确定为其分配的资源的时域位置的位图(bitmap)的起始位置，从而使终端设备1或终端设备2根据该目标位置及bitmap确定该资源的时域位置。例如，bitmap可以为10010，目标时域位置为子帧n+i，则表示基站为终端设备1分配的资源所在子帧为：子帧n+i和子帧n+i+3，当然，bitmap可以是在第一调度信息中指示的，也可以是基站预先与终端设备1及终端设备2约定好的。
在具体实施过程中，基站、终端设备1以及终端设备2可以预先约定好第一间隔的含义为上述多种情况中的哪一种，或者，也可以将第一间隔的含义携带在第一调度信息中，例如在第一调度信息中增加一个特定比特位，该比特位的取值可以为0-5，分别对应上述四种情况，则终端设备1在接收到该第一调度信息后便根据该特定比特位的取值确定出第一间隔的含义。需要说明的是，本领域技术人员也可以采用其他方式定义第一间隔，在本申请实施例中不作限制。
在下面的描述中，将以第一时域位置为子帧n，基站给终端设备1分配的资源的时域位置为子帧n+T1，第一间隔指示第一时域位置与该资源的时域位置之间的间隔为例进行说明。则基站在子帧n向终端设备2发送第一调度信息，并通过第一调度信息指示第一间隔。
在本申请实施例中，基站通过第一调度信息指示该第一间隔也有多种方式，具体可以采用如下三种指示方式中的任意一种：
(1)第一指示信息指示的值为L1，通过L1的值指示第一间隔T1，第一间隔T1为L1与预设值k的和。k为大于等于0的整数，k为基站或终端使用的标准协议中规定的，或者 k为基站根据当前网络中的资源使用情况或者其他因素配置的，或者k为网络设备在与终端设备1或终端设备2通信之前预先设置的。
(2)第一指示信息指示的值为L1，通过L1的值指示的第一间隔T1为满足以下两个条件时的最小值：(1)T1大于或等于L1+k个子帧，k为大于等于0的整数，k为基站或终端设备使用的标准协议中规定的，或者k为基站根据当前网络中的资源使用情况或者其他因素配置的，或者k为网络设备在与终端设备1或终端设备2通信之前预先设置的；(2)子帧n+T1是预设子帧集合中的一个子帧，例如，该预设子帧集合为物理侧行共享信道(Physical sidelink shared channel，PSSCH)资源池的子帧集合中排除掉用于传输侧行链路同步序列(Sidelink Synchronization Sequence，SLSS)的子帧以及排除掉预留子帧的上行子帧集合。
(3)第一指示信息指示的值为L1，通过L1的值指示的第一间隔T1为满足以下两个条件时的最小值：(1)T1大于或等于L1+k个子帧，k为大于等于0的整数，k为基站或终端设备使用的标准协议中规定的，或者k为基站根据当前网络中的资源使用情况或者其他因素配置的，或者k为网络设备在与终端设备1或终端设备2通信之前预先设置的；(2)子帧n+T1为终端设备1用于发送PSSCH的子帧集合中的一个子帧。
类似的，其他第一指示信息指示第一间隔的方法还可以为：第一指示信息指示的值为L1，通过L1的值指示的第一间隔T1为同时满足T1大于或等于L1+k个子帧，以及其他条件的最小值。其中，k为大于等于0的整数，k为基站或终端使用的标准协议中规定的，或者k为基站根据当前网络中的资源使用情况或者其他因素配置的，或者k为网络设备在与终端设备1或终端设备2通信之前预先设置的。
可选的，当终端设备1发送或接收数据的定时与基站发送第一调度信息的定时不同步时，分配的资源的时域位置对应的子帧为：子帧的起始时间不早于{子帧n的起始时间+T1*一个子帧的时域长度-offset}的第一个子帧。例如，offset可以为TA/2，TA是终端设备1的定时提前量，TA＝N TA*Ts，Ts是帧结构中的基本时间单元，可以理解为采样时间间隔，其值在标准中规定，比如Ts＝1ms/30720。N TA是基站配置的。又如，offset可以为TA/2+N TA  offset*Ts，其中N TA offset的值在标准中规定。
在下面的描述中，将以基站采用第一种指示方式为例进行说明，即，第一指示信息指示L1，L1+k＝T1。
当基站确定了为终端设备1分配的资源为子帧n+T1以及确定第一指示信息指示L1后，则向终端设备1发送包含第一指示信息的第一调度信息。例如，第一调度信息可以是通过物理下行控制信道(Physical downlink control channel，PDCCH)发送的下行控制信息(Downlink control information，DCI)，当然，也可以是通过其他物理下行信道发送的信息，在本申请实施例中不作限制。
步骤22：终端设备2在第二时域位置向终端设备1发送第二调度信息，其中，该第二调度信息中包含第二指示信息。
当基站在第一时域位置向终端设备2发送第一调度信息后，终端设备2则在第一时域位置接收到该第一调度信息。
在本申请实施例中，由于终端设备2与基站进行通信时，需要获取与基站的定时同步。当终端设备2获取了基站的定时同步后，基站在第一时域位置，即子帧n，发送第一调度信息，则终端设备2可以确定其在该第一时域位置，即子帧n，接收到该第一调度信息。
在本申请实施例中，终端设备2在第二时域位置发送第二调度信息可以采用如下两种方式中的任意一种。
第一种发送方式：终端设备2在第一时域位置接收到该第一调度信息后，则根据第一时域位置及已知的第三间隔，确定第二时域位置。其中，该第三间隔是在终端设备使用的标准协议中规定的，或者是由基站配置的，或者是预配置的。请参考图3，终端设备2在子帧n接收到该第一调度信息，该第三间隔为m个子帧，则终端设备2确定第二时域位置为子帧n+m。终端设备2还需确定第二调度信息中包含的第二指示信息。在本申请实施例中，第二指示信息用于指示第二间隔，该第二间隔为第一间隔与第三间隔的差值。具体来讲，终端设备2在子帧n接收到该第一调度信息，获取该第一调度信息中的第一指示信息指示的值为L1，则根据预设的k值，终端设备2确定第一指示信息指示的第一间隔为L1+k个子帧，从而确定第二间隔为L1+k-m个子帧，然后用第二指示信息指示该第二间隔。
可选的，当终端设备2发送第二调度信息的定时与接收第一调度信息的定时不同步时，第二时域位置对应的子帧为：子帧的起始时间不早于{子帧n的起始时间+第三间隔*一个子帧的时域长度-offset}的第一个子帧。例如，offset可以为TA/2，TA是终端设备1的定时提前量，TA＝N TA*Ts，Ts是帧结构中的基本时间单元，可以理解为采样时间间隔，其值在标准中规定，比如Ts＝1ms/30720。N TA是基站配置的。又如，offset可以为TA/2+N TA offset*Ts，其中N TA offset的值在标准中规定。
第二种发送方式：终端设备在接收到该第一调度信息后，选择在第一时域位置后的一个时域位置发送第二调度信息，该选择的一个时域位置即为第二时域位置，例如第二时域位置为子帧n+m。然后终端设备2根据第二时域位置确定第二调度信息中包含的第二指示信息。第二指示信息用于指示第二间隔，该第二间隔为第一间隔与第三间隔的差值，其中，第三间隔为第二时域位置与第一时域位置的差值，也就是L1+k-m。
需要说明的是，终端设备2通过第二指示信息指示该第二间隔的方式可以采用步骤21中基站通过第一指示信息指示第一间隔的三种指示方式中的任意一种，在此不再赘述。具体来讲，终端设备2通过第二指示信息指示第二间隔的方式可以与步骤21中基站通过第一指示信息指示第一间隔的方式相同，例如，都采用第一种指示方式。当然，也可以不同，例如，基站通过第一指示信息指示第一间隔的方式为第一指示方式，终端设备2通过第二指示信息指示第二间隔的方式为第二指示方式。终端设备2也可以根据实际情况选择其中任意一种方式进行指示。当然，若终端设备2根据实际情况选择了一种指示方式，则需要将该指示方式通知给终端设备1，具体的通知方式在此不作限制。
在下面的描述中，将以终端设备2通过第二指示信息指示第二间隔的方式为步骤21中的第一种指示方式为例进行说明。若终端设备2采用第一种发送方式发送第二调度信息，则，终端设备2确定第二指示信息指示的值为L1-m。
当终端设备2确定第二时域位置及第二调度信息后，则在第二时域位置向终端设备1发送该第二调度信息。例如，通过物理侧行控制信道(Physical Sidelink Control Channel，PSCCH)发送侧行链路控制信息(Sidelink control information，SCI)，当然，也可以是通过其他物理信道发送的信息，在本申请实施例中不作限制。
步骤23：终端设备1接收该第二调度信息，并确定目标时域位置。
当终端设备2在第二时域位置向终端设备1发送第二调度信息后，终端设备1则在第 二时域位置接收到该第二调度信息。
在本申请实施例中，由于终端设备1与终端设备2进行通信时，需要获取与终端设备2的定时同步，因此，终端设备1在获取终端设备2的定时同步后，终端设备2在第二时域位置，即子帧n+m，发送第二调度信息，则终端设备1可以确定其在该第二时域位置，即子帧n+m，接收到该第二调度信息。
当终端设备1在第二时域位置接收该第二调度信息后，则确定目标时域位置为第二时域位置与第二调度信息中指示的第二间隔的和值对应的时域位置，从而根据目标时域位置确定终端设备1发送和/或接收数据的时域资源。需要说明的是，终端设备2通过第二指示信息指示该第二间隔的方式可以采用步骤21中基站通过第一指示信息指示第一间隔的三种指示方式中的任意一种，在此不再赘述。终端设备1根据目标时域位置确定发送和/或接收数据的时域资源的方式可以采用步骤21中目标时域位置与该资源的时域位置的四种情况确定。
请参考图3，终端设备1在子帧n+m接收第二调度信息，获取该第二调度信息中指示的值为L1-m，用于指示第二间隔，在本申请实施例中，终端设备1能够预先获知终端设备2中第二指示信息指示第二间隔的指示方式，即在终端设备2通过第二指示信息指示第二间隔的方式为步骤21中的第一种指示方式的情况下，终端设备1能够知道该第二间隔为该第二指示信息中指示的值与步骤21中k的和，例如，第二调度信息中携带了第二指示信息指示该第二间隔的方式或者第二指示信息指示该第二间隔的方式是终端设备1与终端设备2预先约定好的，当然，也可以有其他方式，在此不作限制。从而确定为其分配的资源的时域位置为子帧n+m+(L1-m+k)＝n+L1+k＝n+T1，完成基站将为终端设备1分配的时域资源通过终端设备1指示给终端设备2的过程。
可选的，当终端设备1发送或接收数据的定时与接收第二调度信息的定时不同步时，目标时域位置对应的子帧为：子帧的起始时间不早于{子帧n+m的起始时间+第二间隔*一个子帧的时域长度-offset}的第一个子帧。例如，offset可以为TA/2，TA是终端设备1的定时提前量，TA＝N TA*Ts，Ts是帧结构中的基本时间单元，可以理解为采样时间间隔，其值在标准中规定，比如Ts＝1ms/30720。N TA是基站配置的。又如，offset可以为TA/2+N TA offset*Ts，其中N TA offset的值在标准中规定。
请参考图4，为本申请另一实施例提供的一种资源指示方法，该方法的流程如下。
步骤41：基站在第一时域位置向终端设备2发送第一调度信息，其中，所述第一调度信息包含第一指示信息，所述第一指示信息用于指示第一间隔。
步骤41的具体实现过程与步骤21相同，在此不再赘述。在本申请实施例中，以第一时域位置为子帧n，基站确定为终端设备1分配的资源为子帧n+T1，以及基站通过步骤21中的第一种指示方式向终端设备2指示第一间隔且第一指示信息指示的值为L1为例进行说明，如图5所示。
步骤42：终端设备2接收该第一调度信息，并确定第二时域位置。
当基站在第一时域位置向终端设备2发送第一调度信息后，终端设备2则在第一时域位置接收到该第一调度信息。
在本申请实施例中，由于终端设备2与基站进行通信时，需要获取与基站的定时同步。当终端设备2获取了基站的定时同步后，基站在第一时域位置，即子帧n，发送第一调度信 息，则终端设备2可以确定其在该第一时域位置，即子帧n，接收到该第一调度信息。
当终端设备2在第一时域位置接收该第一调度信息后，则根据第一时域位置确定第二时域值。在本申请实施例中，该第二时域位置为该第一时域位置与第三间隔的和值，该第三间隔为该第一间隔与第二间隔的差值；其中，该第二间隔为预先定义的，或为所述网络设备配置的，或为预配置的，该第二间隔是终端设备1以及终端设备2都预先获知的。请参考图5，终端设备2在子帧n接收第一调度信息，获取第一指示信息中指示的值为L1，终端设备2能够预先获知基站中通过第一指示信息指示第一间隔的指示方式，即终端设备1能够知道该第一间隔为该第一指示信息中指示的值与预设的k值的和，例如，第一调度信息中携带了第一指示信息指示该第一间隔的方式或者第一指示信息指示该第一间隔的方式是基站与终端设备2预先约定好的，当然，也可以有其他方式，在此不作限制。从而，终端设备2确定第一间隔为L1+k个子帧。然后，终端设备根据预先设置的第二间隔为T2个子帧，确定第三间隔为L1+k-T2个子帧，最终根据子帧n及第三间隔L1+k-T2个子帧的和为第二时域位置，即第二时域位置为子帧n+L1+k-T2。
可选的，当终端设备2与终端设备1通信的定时与接收第一调度信息的定时不同步时，第二时域位置对应的子帧为：子帧的起始时间不早于{子帧n的起始时间+第三间隔*一个子帧的时域长度-offset}的第一个子帧。例如，offset可以为TA/2，TA是终端设备2的定时提前量，TA＝N TA*Ts，Ts是帧结构中的基本时间单元，可以理解为采样时间间隔，其值在标准中规定，比如Ts＝1ms/30720。N TA是基站配置的。又如，offset可以为TA/2+N TA offset*Ts，其中N TA offset的值在标准中规定。
步骤43：终端设备2在该第二时域位置向终端设备1发送第二调度信息。
在本申请实施例中，该第二调度信息用于使终端设备1确定终端设备1目标时域位置为该第二时域位置与该第二间隔的和值，从而根据目标时域位置确定用于发送和/或接收数据的时域资源的位置。在这种情况下，第二调度信息中不包含用于指示该时域资源的指示信息。需要说明的是，若第一调度信息中包含了指示给终端设备1的频域位置或其他配置信息，该第二调度信息中也可以包含第一调度信息中指示的频域位置或该其他配置信息。第二调度信息的类型与步骤22中相同，例如可以为SCI，在此不再赘述。
步骤44：终端设备1接收该第二调度信息，并确定目标时域位置。
当终端设备2在第二时域位置向终端设备1发送第二调度信息后，终端设备1则在该第二时域位置接收到该第二调度信息。
在本申请实施例中，由于终端设备1与终端设备2进行通信时，需要获取与终端设备2的定时同步，因此，终端设备1在获取终端设备2的定时同步后，终端设备2在第二时域位置，即子帧n+L1+k-T2，发送第二调度信息，则终端设备1可以确定其在该第二时域位置，即子帧n+L1+k-T2，接收到该第二调度信息。
当终端设备1在第二时域位置接收该第二调度信息后，则确定目标时域位置为该第二时域位置与该第二间隔的和值。请参考图5，终端设备1在子帧n+L1+k-T2接收到该第二调度信息后，则根据预先设置好的第二间隔T2，确定目标时域位置为子帧n+L1+k-T2+T2＝n+L1+k，从而根据目标时域位置确定终端设备1发送和/或接收数据的时域资源，完成基站将为终端设备1分配的时域资源通过终端设备1指示给终端设备2的过程。需要说明的是，终端设备1根据目标时域位置确定发送和/或接收数据的时域资源的方式可以采用步骤21中 目标时域位置与该资源的时域位置的四种情况确定，在此不再赘述。
可选的，当终端设备1发送或接收数据的定时与接收第二调度信息的定时不同步时，目标时域位置对应的子帧为：子帧的起始时间不早于{子帧n+m的起始时间+第二间隔*一个子帧的时域长度-offset}的第一个子帧。例如，offset可以为TA/2，TA是终端设备1的定时提前量，TA＝N TA*Ts，Ts是帧结构中的基本时间单元，可以理解为采样时间间隔，其值在标准中规定，比如Ts＝1ms/30720。N TA是基站配置的。又如，offset可以为TA/2+N TA offset*Ts，其中N TA offset的值在标准中规定。
请参考图6，为本申请另一实施例提供的一种资源指示方法，该方法的流程如下。
步骤61：基站在第一时域位置向终端设备2发送第一调度信息，其中，所述第一调度信息包含第一指示信息及第二指示信息，所述第一指示信息用于指示第一间隔，所述第二指示信息用于指示第二间隔。
在具体实施过程中，在基站向终端设备2发送第一调度信息之前，首先需要确定给终端设备1分配的资源的时域位置，该过程与步骤21中相应的过程相同，在此不再赘述。在下面的描述中，将以第一时域位置为子帧n，基站为终端设备1分配的资源的时域位置为子帧n+T1为例进行说明。
基站还需要确定终端2发送第二调度信息的时域位置，并根据第一时域位置及终端2发送第二调度信息的时域位置确定第一指示信息，根据终端2发送第二调度信息的时域位置和为终端设备1分配的资源的时域位置确定第二指示信息。其中，第一指示信息中包含的第一间隔用于指示终端设备2发送第二调度信息的时域位置与第一时域位置的差值，第二指示信息中包含的第二间隔用于目标时域位置与终端设备2发送第二调度信息的时域位置的差值。第一间隔与第二间隔的和值为目标时域位置与第一时域位置的差值，即第一间隔与第二间隔的和值为T1。

在本申请实施例中，由于终端设备1与终端设备2进行通信时，需要获取与终端设备2的定时同步，因此，终端设备1在获取终端设备2的定时同步后，终端设备2在第二时域位置，即子帧n+L1+k，发送第二调度信息，则终端设备1可以确定其在该第二时域位置，即子帧n+L1+k，接收到该第二调度信息。
当终端设备1在第二时域位置接收该第二调度信息后，则确定目标时域位置为该第二时域位置与该第二间隔的和值。当然，终端设备1能够预先获知终端设备1中通过第二指示信息指示第二间隔的指示方式，即在终端设备2通过第三指示信息指示第二间隔的方式为步骤21中的第一种指示方式的情况下，终端设备1能够知道该第二间隔为该第二指示信息中指示的值与k的和。例如，第一调度信息中携带了第一指示信息指示该第一间隔的方式或者第一指示信息指示该第一间隔的方式是基站与终端设备2预先约定好的，当然，也可以有其他方式，在此不作限制。请参考图7，终端设备1在子帧n+L1+k接收到该第二调度信息后，则根据第二调度信息中指示的值L2，确定目标时域位置为子帧n+L1+k+L2+k＝n+T1，从而根据目标时域位置确定终端设备1发送和/或接收数据的时域资源，完成基站将为终端设备1分配的时域资源通过终端设备1指示给终端设备2的过程。需要说明的是，终端设备1根据目标时域位置确定发送和/或接收数据的时域资源的方式可 以采用步骤21中目标时域位置与该资源的时域位置的四种情况确定，在此不再赘述。

当终端设备1在第二时域位置接收该第二调度信息后，则确定目标时域资源的位置为该第二时域位置与第二间隔的和值，该第二间隔为该预先设置的第三间隔与该第一指示信息中指示的第一间隔的差值。请参考图15，终端设备1在子帧n+m接收到该第二调度信息后，则根据预先设置好的第三间隔T1，确定目标时域位置为子帧n+m+(T1-m)＝n+T1，从而根据目标时域位置确定终端设备1发送和/或接收数据的时域资源，完成基站将为终端设备1分配的时域资源通过终端设备1指示给终端设备2的过程。
需要说明的是，终端设备1根据目标时域位置确定发送和/或接收数据的时域资源的方式可以采用步骤21中目标时域位置与该资源的时域位置的四种情况确定，在此不再赘述。
可选的，当终端设备1发送或接收数据的定时与接收第二调度信息的定时不同步时，目标时域位置对应的子帧为：子帧的起始时间不早于{子帧n+m的起始时间+第二间隔*一个子帧的时域长度-offset}的第一个子帧。例如，offset可以为TA/2，TA是终端设备1的定时提前量，TA＝N TA*Ts，Ts是帧结构中的基本时间单元，可以理解为采样时间间隔，其值在标准中规定，比如Ts＝1ms/30720。N TA是基站配置的。又如，offset可以为TA/2+N TA offset*Ts，其中N TA offset的值在标准中规定。
在上述技术方案中，通过合理的设计第一调度信息及第二调度信息中指示的内容、发送调度信息的时刻以及网络设备、第一设备和第二设备中预设的间隔，使第二设备在接收到第一设备发送的调度信息后，能够根据该调度信息确定出网络设备为其分配的时域资源，可以实现通过第一设备转发网络设备对第二设备的调度信令的过程。
