具体实施方式
为了便于理解，首先，对本申请所涉及的概念进行说明。
终端设备：是一种具有无线收发功能的设备。终端设备可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、车载终端设备、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备、可穿戴终端设备等。本申请实施例所涉及的终端设备还可以称为终端、用户设备(user equipment，UE)、接入终端设备、车载终端、工业控制终端、UE单元、UE站、移动站、移动台、远方站、远程终端设备、移动设备、UE终端设备、无线通信设备、UE代理或UE装置等。终端设备也可以是固定的或者移动的。

时间单元：是指时域资源，一个时间单元中可以包括多个子时间单元。例如，时间单元可以为时隙，子时间单元可以为符号。又例如，时间单元可以为子帧，子时间单元可以为时隙或符号。为了便于描述，在下文中，以时间单元为时隙，子时间单元为符号为例进行说明。
旁链路(sideline)通信：是指终端设备与终端设备之间的通信。终端设备与终端设备之间的链路称为旁链路。其中，旁链路也可以称为设备到设备(device-to-device，D2D)链路、边链路、侧链路等，本申请实施例对此不做限定。旁链路的信道可以包括物理旁链路控制信道(physical sidelink control channel，PSCCH)、物理旁链路共享信道(physical sidelink shared channel，PSSCH)、旁链路反馈信道(physical sidelink feedback channel，PSFCH)、物理侧行广播信道(physical sidelink broadcast channel，PSBCH)等。
旁链路资源：旁链路资源可以包括PSSCH资源和PSCCH资源。PSSCH用于承载数据(data)信息，即，PSSCH资源用于传输数据信息。PSCCH用于承载旁链路控制信息(sidelink control information，SCI)，即，PSCCH资源用于传输SCI。SCI中的信息可以称为SA(调度分配，scheduling assignment)，SA是指用于进行数据调度的相关信息，例如，SA可以用于指示PSSCH的资源分配、调制编码方式。PSSCH资源还可以称为数据资源(data资源)，PSCCH资源还可以称为SA资源。
在侧行通信过程中，终端设备之间的传输方式包括：单播传输、组播传输和广播传输。下面，分别结合图1A-图1C介绍该三种传输方式。
单播传输：单播传输的接收终端通常为一个。下面，结合图1A介绍单播传输。
图1A为本申请实施例提供的单播传输的示意图。请参见图1A，包括终端设备101和终端设备102，终端设备101和终端设备102之间进行单播传输。终端设备102可以接收终端设备101的发送的数据，终端设备101也可以接收终端设备102发送的数据。
组播传输：在组播传输中，接收设备可以是一个通信组内的所有终端设备，也可以为与发送设备之间距离小于预设距离的终端设备。下面，结合图1B介绍单播传输。
图1B本申请实施例提供的组播传输的示意图。请参见图1B，包括终端设备101、终端设备102、终端设备103和终端设备104。该4个终端设备可以构成一个通信组，该通信组内的终端设备之间进行组播传输。终端设备102、终端设备103和终端设备104均可以接收到终端设备101发送的数据。
广播传输：在广播传输中，接收终端可以为发送终端周围的任意一个终端设备。下面，结合图1C介绍广播传输。

在NR车辆到其他设备(vehicle to everything，V2X)中引入2阶SCI，第一阶SCI承载在PSCCH中，用于指示PSSCH的传输资源、预留资源信息、MCS等级、优先级等信息。第二阶SCI在PSSCH的资源中发送，利用PSSCH的解调参考信号(demodulation reference signal，DMRS)进行解调，用于指示发送端ID、接收端ID、混合自动重传请求(hybrid automatic repeat request，HARQ)ID、新传输块指示(NDI，new data indicator)等用于数据解调的信息。下面，结合图3，通过PSCCH和PSSCH的帧结构对2阶SCI进行介绍。
图2为本申请实施例提供的帧结构示意图。请参见图2，一个帧结构对应的时长可以为一个时隙，该帧结构中包括14个符号。符号0用于传输自动增益控制(automatic gain control，AGC)。符号1、符号2和符号3用于传输PSCCH。符号4和符号11用于传输DMRS。第二阶SCI在符号4、符号5和符号6上映射，其中，第二阶SCI和DMRS在符号4上频分复用，第二阶SCI占据的资源大小与第二阶SCI的比特数相关。其它符号用于传输PSSCH。
在不同的网络覆盖情况下，终端设备获取旁链路资源的方式可能也不相同。为了便于理解，首先，结合图3A-图3C，介绍三种网络覆盖情况。
图3A为本申请实施例提供的一种网络覆盖情况的示意图。请参见图3A，包括网络设备301、终端设备302和终端设备303。终端设备302和终端设备303均处于同一网络设备的覆盖范围内，终端设备302和终端设备303之间可以进行侧行通信。终端设备302和终端设备303均可以接收来自网络设备的配置指令，并基于配置指令进行通信。
图3B为本申请实施例提供的另一种网络覆盖情况的示意图。请参见图3B，包括网络设备301、终端设备302和终端设备303。终端设备302处于网络设备的覆盖范围内，终端设备303未处于网络设备的覆盖范围内，终端设备302和终端设备303之间可以进行侧行通信。终端设备302可以接收来自网络设备的配置指令，并基于配置指令进行通信。终端设备303无法接收到网络设备的配置指令，终端设备303可以根据预配置(pre-configuration)信息及位于网络覆盖范围内的终端设备(例如终端设备302)发送的PSBCH中携带的信息确定侧行配置，以进行侧行通信。
图3C为本申请实施例提供的又一种网络覆盖情况的示意图。请参见图3C，包括终端设备302和终端设备303。终端设备302和终端设备303均处于网络设备的覆盖范围之外，终端设备302和终端设备303之间可以进行侧行通信。终端设备302和终端设备303可以根据预配置(pre-configuration)信息确定侧行配置，以进行侧行通信。
在上述网络覆盖情况下，下面，介绍终端设备的两种资源获取方式。
第一种资源获取方式：网络设备向终端设备分配资源，终端设备根据网络设备分配的资源进行数据传输。网络设备可以为终端设备分配单次传输的资源，也可以为终端设备分配半静态传输的资源。例如，请参见图3A，则终端设备302和终端设备303可以通过网络设备301分配的资源进行数据传输。例如，请参见图3B，终端设备302可以通过网络设备301分配的资源进行数据传输
第二种资源获取方式：终端设备在资源池中选择资源进行数据传输。该资源池可以为网络设备分配的资源池，也可以为预配置的资源池。例如，请参见图3A，终端设备302和终端设备303可以在网络设 备301分配的资源池中选择资源进行数据传输。例如，请参见图3B，终端设备302可以在网络设备301分配的资源池中选择资源进行数据传输，终端设备303可以在预配置的资源池中选择资源进行数据传输。例如，请参见图3C，终端设备302和终端设备303可以在预配置的资源池中选择资源进行数据传输。
在第二种资源获取方式中，若终端设备随机在资源池中选择资源，则出现资源冲突的概率较大，或者资源的利用率较低。终端设备还可以侦听其它终端设备的预留资源(终端设备在未来时段可能会使用的资源)，若终端设备侦听到其它设备预留了某资源，则终端设备不再使用该资源。然而，根据侦听结果选择资源依然可能会出现资源冲突，或者资源利用率较低。终端设备的侦听过程可以为：终端设备接收其它终端设备发送的PSCCH，PSCCH中包括其它终端设备预留的资源，终端设备根据接收到的PSCCH确定其它终端设备预留的资源。预留的资源通常为终端设备在未来时段进行数据传输所使用的资源。
下面，对基于侦听进行资源选择过程中存在的问题进行说明。
第一种情况：
终端设备通常在一定范围内进行侦听，无法侦听到距离较远的终端设备预留的资源，使得该终端设备可能会与距离其较远的其它终端设备使用相同的资源，进而可能导致资源冲突。下面，结合图4A，对该种情况进行说明。
图4A为本申请实施例提供的一种数据传输场景的示意图。请参见图4A，包括终端设备A、终端设备B和终端设备C。终端设备B与终端设备C的距离较远，终端设备A位于终端设备B和终端设备C之间。在侦听过程中，终端设备B和终端设备C由于距离较远，使得终端设备B和终端设备C无法获取到对方预留的资源，导致终端设备B和终端设备C有可能使用相同的资源向终端设备A发送数据(PSSCH)，进而导致终端设备B和终端设备C之间的干扰较大。
第二种情况：
由于半双工的限制，终端设备在发送数据的同时，无法接收来自其它终端设备的数据。这样，在终端设备发送的过程中，无法侦听其它终端设备的预留资源，为了避免资源冲突，终端设备在资源选择时，将未侦听到的所有可能的资源全部排除掉，这样，终端设备可能排除了过多的资源，导致部分资源未得到充分利用，进而导致资源利用率较低。
第三种情况：
终端设备在监听到其它终端设备预留某资源之后，终端设备则不再使用该资源。然而，若两个终端设备使用相同的资源分别向两个距离很远的终端设备发送数据，也不会存在较大干扰，在该种情况下，若终端设备不使用其它终端设备的预留资源，可能会导致资源利用率较低。下面，结合图4B，对该种情况进行说明。
图4B为本申请实施例提供的一种数据传输场景的示意图。请参见图4B，包括终端设备A、终端设备B、终端设备C和终端设备D。终端设备B和终端设备C的距离较近，终端设备A和终端设备D的距离较远。在该种情况下，即使终端设备B向终端设备A发送数据所使用的资源，与终端设备C向终端设备D发送数据所使用的资源相同，也不会影响终端设备A和终端设备D接收数据的成功率。然而，终端设备B和终端设备C可以监听到对方的预留资源，若终端设备B监听到终端设备C预留了某资源，则终端设备B不再使用该资源向终端设备A发送数据，但是，若终端设备C预留的该资源是向终端设备D发送数据，则导致资源的利用率较低。
为了解决上述问题，在本申请实施例中，第一终端设备可以在适当的时段内向第二终端设备发送第一资源集合，以使第二终端设备可以及时获取到第一资源集合，并在进行资源选择时参考该第一资源集合，进而降低第二终端设备与其它终端设备之间出现资源冲突的概率，以及提高资源的利用率。
下面，通过具体实施例对本申请实施例提供的方法进行详细说明。需要说明的是，下面几个具体实施例可以单独存在，也可以相互结合，对于相同或相似的内容，在不同的实施例中不再重复说明。
图5为本申请实施例提供的一种通信方法的流程示意图。请参见图5，该方法可以包括：
S501、第一终端设备确定第一时段。
第一时段为第一终端设备向第二终端设备发送第一资源集合的时段，用于使得第二终端设备可以及时获取得到第一资源集合。
第一终端设备可以根据第一信息确定第一时段。第一信息包括如下信息中的至少一种：
第一终端设备从第二终端设备接收到的请求消息；或者，
第一终端设备的侦听信息；或者，
第一终端设备的资源重选操作。
当第一信息为请求消息时，则第一时段可以为第一设备接收到请求消息之后的第一时长内的时段。即，在第一终端设备接收到第二终端设备发送的请求消息之后，第一终端设备在第一时长内，向第二终 端设备发送第一资源集合。请求消息用于请求获取第一资源集合；或者，请求消息用于请求启动或重置定时器，定时器的时长为第一时长。
当第一信息为侦听信息时，第一终端设备可以在第一时刻，根据侦听信息判断第一条件是否满足，若是，则将第一时刻之后的第二时长内的时段确定为第一时段。即，若在第一时刻，第一终端设备根据侦听信息判断第一条件满足时，则终端设备在第二预设试产内，向第二终端设备发送第一资源集合。在后续实施例对第一条件进行介绍，此处不再进行赘述。
当第一信息为资源重选操作时，第一时段为第一终端设备进行资源重选操作之后第三时长内的时段。即，在第一终端设备执行完资源重选操作之后，第一终端设备在第三时长内向第二终端设备发送第一资源集合。
S502、第一终端设备在第一时段内向第二终端设备发送第一资源集合。
第一终端设备可以通过旁链路(sidelink)向第二终端设备发送第一资源集合。
在不同的情况下，第一资源集合中包括的内容也不同。例如，第一资源集合中可以包括第一终端设备的预留资源，第二终端设备的预留资源中在未来时段可能会出现资源冲突的资源等。在后续实施例中对第一资源集合进行说明，此处不再进行赘述。
S503、第二终端设备根据第一资源集合进行资源选择。
第二终端设备具有预留资源，第二终端设备可以根据接收到的第一资源集合和预留资源进行资源选择，并根据选择的资源进行信息发送。
在图5所示的实施例中，第一终端设备可以确定第一时段，并在第一时段内向第二终端设备发送第一资源集合，以使第二终端设备可以及时接收到第一资源集合，并在进行资源选择时参考该第一资源集合，进而降低第二终端设备与其它终端设备之间出现资源冲突的概率，以及提高资源的利用率。
第一终端设备可以根据第一信息确定第一时段。当第一信息不同时，第一终端设备确定第一时段的过程不同，第一终端设备向第二终端设备发送的第一资源集合可能也不同。下面，通过图6-图13所示的实施例进行说明。
图6为本申请实施例提供的另一种通信方法的流程示意图。请参见图6，该方法可以包括：
S601、第二终端设备向第一终端设备发送请求消息。
其中，请求消息用于向第一终端设备请求获取第一资源集合。
可选的，在第二终端设备需要进行资源重选时，第二终端设备向第一终端设备发送请求消息。例如，在第二终端设备的业务周期发生变化，或者第二终端设备一种业务处理完成时，第二终端设备可以向第一终端设备发送请求消息。
请求消息的承载方式包括如下至少一种：通过SCI承载、通过媒体接入层控制单元(medium access control cell，MAC CE)承载、通过侧行无线资源控制(radio resource control，RRC)消息承载。
当通过SCI承载请求消息时，可以将SCI中预设字段的值设置为预设值，以指示第二终端设备向第一终端设备发送请求消息。换句话说，请求消息可以为SCI，且SCI中预设字段的值为预设值。即，若第一终端设备接收到SCI，且SCI中预设字段的值为预设值，则第一终端设备确定接收到请求消息。例如，预设字段可以为某个特定保留比特，预设值可以为1。该SCI可以通过PSCCH承载(第一阶SCI)，也可以通过PSSCH承载(第二阶SCI)。
当通过MAC CE承载请求消息时，MAC CE中包括最小时间偏移值和最大时间偏移值，最小时间偏移值和最大时间偏移值不同。换句话说，请求消息可以为MAC CE，且MAC CE中包括的最小时间偏移值和最大时间偏移值不同。即，若第一终端设备接收到包括最小时间偏移值和最大时间偏移值的MAC CE，且最小时间偏移值和最大时间偏移值不同，则第一终端设备确定接收到请求消息。该MAC CE可以通过PSSCH承载。
侧行RRC消息可以通过PSSCH承载侧行RRC。
S602、第一终端设备根据请求消息，确定第一时段。
第一时段可以为第一终端设备接收到请求消息之后第一时长内的时段。
可以通过如下两种方式表示第一时段：
第一种方式：第一时段为[T_request+T_min，T_request+T_max]。
其中，T_request可以为第一终端设备接收到请求消息的时刻，或者，T_request可以为第一终端设备接收到请求消息的时刻所在时隙的终点或起点。
T_min和T_max的单位可以为毫秒，T_min的值可以为零。
可选的，可以在请求消息中携带T_min，T_max的值，或者，T_min，T_max的值可以由网络设备配置、预配置或标准定义。
第二种方式：第一时段为[n_request+n_min，n_request+n_max]。
其中，n_request为第一终端设备接收到请求消息的时隙。
n_min和n_max可以为物理时隙个数，或者为第二终端设备所在发送资源池内的时隙个数，或者为第一终端设备所在发送资源池内的时隙个数。n_min的值可以为零。当请求消息通过SCI承载时，n_max的值可以为2*T_R，其中T_R表示SCI中指示的资源预留周期(resource reservation period)域的值。
可选的，可以在请求消息中携带n_min和n_max的值，或者，n_min和n_max的值可以由网络设备配置、预配置或标准定义。
S603、第一终端设备在第一时段内向第二终端设备发送第一资源集合。
可选的，第一资源集合中可以包括第一终端设备的预留资源；或者，第一资源集合可以包括第一终端设备向第二终端设备推荐使用的资源；或者，第一资源集合可以包括冲突资源，冲突资源为第二终端设备与其它终端设备预留的相同的资源。第一终端设备可以通过监听确定向第二终端设备推荐使用的资源或者冲突资源。冲突资源还可以称为碰撞资源。
需要说明的是，第一资源集合还可以为其它，只要第一资源集合可以用于辅助第二终端设备进行资源选择，以降低资源冲突概率或提高资源利用率即可。
S604、第二终端设备根据第一资源集合进行资源选择。
若第二终端设备在第二时刻接收到第一资源集合，则第二终端设备进行资源选择时资源选择窗的起点可以不早于第二时刻，第二时刻可以为一个时隙的起始时刻或者终止时刻。
可选的，假设第一资源集合中包括第一终端设备向第二终端设备推荐使用的资源，则在第二终端设备在预留资源中进行资源选择时，可以确定预留资源(资源选择窗)与第一资源集合中时域重叠的资源，并在时域重叠的资源中进行资源选择。下面，结合图7进行说明。
图7为本申请实施例提供的一种资源选择示意图。请参见图7，第二终端设备接收到的第一资源集合的时域范围为t2至t4，第二终端设备的资源选择窗的时域范围为t1至t3，则第一资源集合和资源选择窗内资源的重叠资源为t2至t3之间的资源，则第二终端设备可以在t2至t3之间的资源上进行资源选择。由于该第一资源集合为第一终端设备通过监听的方式确定得到的，若第二终端设备使用该第一资源集合中的资源，则与其它终端设备发生资源冲突的概率较小，且资源利用率较高。

请求消息的承载方式包括如下至少一种：通过SCI承载、通过MAC CE承载、通过侧行RRC承载。
当通过SCI承载请求消息时，可以将SCI中预设字段的值设置为预设值，以指示第二终端设备向第一终端设备发送请求消息。换句话说，请求消息可以为SCI，且SCI中预设字段的值为预设值。即，若第一终端设备接收到SCI，且SCI中预设字段的值为预设值，则第一终端设备确定接收到请求消息。例如，预设字段可以为某个特定保留比特，预设值可以为1。
可以通过PSSCH承载SCI(第二阶SCI)、MAC CE或者侧行RRC消息。

S902、第一终端设备在第一时刻根据侦听信息确定第一条件满足。
其中，第一条件为：在第二资源集合中的一个或多个资源上的干扰大于或等于第一阈值。所述第二资源集合为第二终端设备位于第二时段内的预留资源，第二时段位于第一时段之后。
第一时刻可以为确定第一条件满足的时刻，或者，第一时刻可以为确定第一条件满足的时刻所在的时隙的起始时刻或者终止时刻。
第一终端设备可以通过如下方式确定得到在第二资源集合中的一个或多个资源上的干扰大于或等于第一阈值：第一终端设备可以接收其它终端设备发送的PSCCH，PSCCH中可以包括其它终端设备的预留资源。当第一终端设备确定第四终端设备的预留资源与第二终端设备的预留资源存在重叠时，当第一终端设备可以对第四终端设备的PSCCH-侧行参考信号接收功率(reference signal received power，RSRP)或者PSSCH-RSRP进行测量，若测量得到的PSCCH-RSRP或者PSSCH-RSRP大于或等于第一阈值，则确定在第二资源集合中的一个或多个资源上的干扰大于或等于第一阈值。

若第二终端设备发送数据的优先级大于第四终端设备发送数据的优先级，并且第四终端设备也具有根据第一资源集合进行资源选择的功能，则第一阈值的取值可以为正无穷大。若第二终端设备发送数据的优先级小于第四终端设备发送数据的优先级，并且第四终端设备不具有根据第一资源集合进行资源选择的功能，则可以根据第一终端设备的能力确定第一阈值。
S903、第一终端设备将第一时刻之后第二时长内的时段确定为第一时段。

S904、第一终端设备在第一时段内向第二终端设备发送第一资源集合。
可选的，第一资源集合包括第二资源集合内干扰大于或等于第一阈值的一个或多个资源。即，第一资源集合中包括第二资源集合内的冲突资源。
S905、第二终端设备根据第一资源集合进行资源选择。
可选的，第二终端设备在进行资源选择时，可以在第二资源集合中剔除第一资源集合中的资源，再进行资源选择。这样，可以避免第二终端设备选择冲突资源。
在图9所示的实施例中，在第一终端设备检测到在第二终端设备的第二资源集合中的一个或多个资源上的干扰大于或等于第一阈值时，第一终端设备可以确定第一时段，并在第一时段内向第二终端设备发送第一资源集合，以使第二终端设备可以及时接收到第一资源集合，并在进行资源选择时参考该第一资源集合，进而降低第二终端设备与其它终端设备之间出现资源冲突的概率，以及提高资源的利用率。

条件2、重叠资源与当前时刻之间的时间差大于或等于第四阈值。
若重叠资源与当前时刻之间的时间差小于第四阈值，则说明第一终端设备无法通过向第二终端设备发送第一资源集合的方式来避免资源冲突。即，只有当第一终端设备有充足的时间向第二终端设备发送第一资源集合，以及第二终端设备具有充足的时间根据第一资源集合进行反应(根据第一资源集合进行资源选择)时，第一终端设备才确定第一时段，以及在第一时段向第二终端设备发送第一资源集合。

可选的，若第一资源集合中包括冲突资源，则第二终端设备可以在第二资源集合(第二终端设备的预留资源)中剔除第一资源集合中的资源，再进行资源选择。这样，可以避免第二终端设备选择冲突资源。

S1203、第一终端设备将第一时刻之后第二时长内的时段确定为第一时段。
第二时长可以由第二终端设备配置，或者网络设备配置，或者预配置，或者标准定义。
可选的，在第一终端设备确定第二条件满足时，第一终端设备将第一时刻之后第二时长内的时段确定为第一时段。
可选的，第二条件包括如下条件中的至少一种：
条件1、第一时间单元与当前时间单元之间的时间差大于或等于第三阈值。
若第一时间单元与当前时间单元之间的时间差小于第三阈值，则说明第一终端设备无法通过向第二终端设备发送第一资源集合的方式来避免资源冲突。即，只有在第一时间单元到达之后，第一终端设备有充足的时间向第二终端设备发送第一资源集合，以及第二终端设备具有充足的时间根据第一资源集合进行反应(根据第一资源集合进行资源选择)时，第一终端设备才确定第一时段，以及在第一时段向第二终端设备发送第一资源集合。

S1205、第二终端设备根据第一资源集合进行资源选择。
可选的，第二终端设备可以在第二资源集合(第二终端设备的预留资源)中剔除第一资源集合中的资源，再进行资源选择，这样，可以避免第二终端设备在第一时间单元向第一终端设备发送需要反馈HARQ的PSSCH，进而避免第一终端设备在第一时间单元内接收过多的需要反馈HARQ的PSSCH。
在图12所示的实施例中，在第一终端设备确定其在未来的第一时间单元内需要接收M个需要反馈HARQ的PSSCH时，第一终端设备可以确定第一时段，并在第一时段内向第二终端设备发送第一资源集合，以使第二终端设备可以及时接收到第一资源集合，并避免在第一时间单元向第一终端设备发送需要反馈HARQ的PSSCH，进而避免第一终端设备在第一时间单元内接收过多的需要反馈HARQ的PSSCH，进而避免第一终端设备出现过载情况。
