还应理解，在本申请实施例中，终端设备也可以指用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的终端设备等。
应理解，本申请实施例中，终端设备可以是安装在汽车里面的通信终端或车载通信设备，还可以是其它能够实现通信功能的模块化、可拆卸的车载终端。终端设备在功能上要能够实现车与车(Vehicle to Vehicle，V2V)、人与车(Vehicle to Pedestrain，V2P)、车与基础设施(Vehicle to Infrastucture，V2I)等业务的信息通讯，这些业务可以统称为V2X业务。因此，本申请实施例中的V2X业务可以包括以下业务中的一种或多种：V2V业务、V2I业务、车与人V2P业务。
在某些实施例中，本申请提及的终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴 的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。

图1给出了本发明实施例应用的一种通信***的示意图。在图1的应用场景中，***100可以包括网络设备102以及终端设备104，106，其中，网络设备与终端设备之间、终端设备与终端设备之间都可以通过无线连接。应理解，图1仅以***包括两个终端设备为例进行说明，但本发明实施例并不限于此，例如，***还可以包括更多的终端设备；类似地，***也可以包括更多的网络设备。还应理解，***也可以称为网络，本发明实施例对此并不限定。
如图1所示，终端设备之间可以进行端到端通信，此时终端设备可以自主选择端到端通信所使用的资源或参数。网络设备也可以调度终端设备进行端到端通信所使用的资源或参数。现有技术中，由于网络设备并不知道终端设备端到端通信的链路的资源的使用情况，因此，网络设备不能合理地调度终端设备端到端通信所使用的资源或参数。此外，当该网络中有多个终端设备时，可能会出现既有被网络设备调度端到端通信所使用的资源或参数的终端设备，同时又有自主选择端到端通信所使用的资源或参数的终端设备的情况，由于网络设备并不知道终端设备自主选择端到端通信所使用的资源或参数，不能合理地为被调度的终端设备调度端到端通信所使用的资源或参数。例如，网络设备进行资源调度时可能会使用已经被自主选择资源的终端设备选择的端到端通信的资源，发生资源碰撞。
基于此，本申请实施例提出了一种通信方法，终端设备可以向网络设备上报侦听结果，用于向网络设备指示资源的使用情况，以避免资源发生碰撞。图2为本申请实施例提供的一种通信方法的示意***互图。
图2所示的通信方法主要可以包括步骤210、步骤220和步骤230。
步骤210，终端设备获取资源的侦听结果，该侦听结果用于指示资源的使用情况，该资源为端到端通信所使用的资源。
应理解，在本申请实施例中，侦听结果用于向网络设备指示资源的使用情况，该侦听结果也可以理解为监测结果或监听结果等。其中，所述的端到端通信指的是两个或多个终端设备之间的通信。
资源的侦听结果可以用于指示以下任意一项或多项：该资源中的特定资源，该资源上的信号强度，该资源上的信号功率，该资源的信道占用比(Channel Busy Ratio，CBR)。
可选地，所述的特定资源的类型可以是可用资源，或不可用资源，或在标准协议中预先定义的符合一定条件的资源。可用资源可以是网络设备能够为终端设备分配的资源，不可用资源可以是网络设备不能够为终端设备分配的资源。一般来说，可用资源表示目前处于空闲或部分空闲的资源，该资源能够为所述终端设备提供服务。不可用资源表示目前处于非空闲的资源，该资源不能为所述终端设备提供服务。其中，特定资源所属的类型可以是终端设备和网络设备之前已协商好的，或者是在标准协议中预先定义的。其中，所述资源可以是时频资源、时域资源、频域资源或载波资源中的一种或多种。
该资源上的信号强度信息可以为接收信号强度指示(Received Signal Strength Indication,RSSI)。
终端设备可以通过侦听资源获取以下任意一项或多项：被其他终端设备预留或占用的资源信息，终端设备接收其他终端设备在资源上发送的参考信号的接收功率信息，终端设备在资源上的接收信号强度或接收功率信息。终端设备可以根据上述任意一项或多项信息，从而确定出侦听结果。
在一些实施中，一个资源被另一终端设备预留或占用，且终端设备接收该另一终端设备在该资源上发送的参考信号的接收功率超过特定阈值，则该资源为不可用资源。或者接收信号强度指示超过特定阈值的资源为不可用资源。在侦听结果用于指示不可用资源的情况下，终端设备在侦听结果中指示该资源信息。又如，一个资源没有被其他终端设备预留，并且该资源上的接收信号强度较低，则该资源为可用资源。在侦听结果用于指示可用资源的情况下，终端设备在侦听结果中指示该资源信息。在基于LTE或NR的V2X通信中，终端设备可以使用或基于LTE Release 14标准协议中定义的侦听过程来获取侦听结果。
步骤220，若满足预设条件，则终端设备向网络设备发送所述侦听结果。
可选地，该预设条件可以包括以下至少一项：
终端设备有待向其它终端设备发送的第一数据；终端设备的特征信息被触发；终端设备被网络设备配置的调度信息将要或已经不可用；终端设备用于向其它终端设备传输数据的载波发生变化；终端设备接收到网络设备发送的第一信息，第一信息用于指示终端设备发送侦听结果；终端设备周期性发送侦听结果的时刻到达。
上述预设条件中的终端设备有待向其它终端设备发送的第一数据，可以包括以下至少一项：
终端设备待向网络设备发送第二信息；第二信息被触发；终端设备已向网络设备发送第二信息；自从上一次终端设备发送第二信息后没有发送过侦听结果；触发终端设备发送第二信息的条件中的至少一种已经被满足；其中，第二信息用于指示第一数据的数量(amount)。
应理解，上述第二信息被触发可以包括第二信息被触发且没有被取消的情况。
第二信息可以为该终端设备进行端到端通信所使用的链路的缓存状态报告(buffer status report，BSR)，例如可以为侧行链路的BSR。
上述预设条件中的终端设备的特征信息被触发，可以包括以下至少一项：
终端设备待向网络设备发送第三信息；第三信息被触发；终端设备已向网络设备发送第三信息；自从上一次终端设备发送第三信息后没有发送过侦听结果；触发终端设备发送第三信息的条件中的至少一种已经被满足；其中，第三信息用于指示终端设备的业务特征信息或业务图样信息，所述特征信息包括业务特征信息或业务图样信息。该业务特征信息或业务图样信息用于指示业务的特征信息，可以包括业务的周期、数据包大小等信息。
应理解，上述第三信息被触发可以包括第三信息被触发且没有被取消的情况。
可选地，终端设备被网络设备配置的调度信息将要或已经不可用，可以包括以下至少一项：
终端设备收到调度释放信息；终端设备已清除调度授权；终端设备的调度清除确认信息被触发。
其中，调度释放信息可以为半静态调度释放信息，调度授权可以为半静态调度授权，调度清除确认信息可以为半静态调度清除确认信息。
可选地，网络设备可以在下行控制信息中包含或指示所述第一信息。例如，网络设备在包含半静态调度释放指示信息的控制信息中指示终端设备需要发送侦听结果或不需要发送侦听结果。在网络设备指示终端设备需要发送侦听结果的情况下，终端设备发送侦听结果。
可选的，网络设备可以配置终端设备周期性报告侦听结果的时域位置。
可选地，在本申请实施例中，该终端设备用于传输数据的载波发生变化可理解为：终端设备用于端到端通信的载波被配置或被重配。终端设备用于端到端通信的载波可能为一个或多个，网络设备可以配置终端设备用于端到端通信的载波。其中，该端到端通信例如可以为侧行链路通信。
需要说明的是，在执行步骤220时，当终端设备确定该预设条件被满足之后，并不一定立即发送所述侦听结果，该终端设备可能会执行一些其它步骤之后再发送所述侦听结果。该预设条件被满足，只是发送所述侦听结果的触发条件，本实施例并不限定一满足预设条件就要立即发送所述侦听结果。
可选的，终端设备可以通过多种方式发送所述侦听结果。例如终端设备可以单独发送所述侦听结果。或者，终端设备可以通过所述第二信息或者所述第三信息来发送所述侦听结果。
例如：当该预设条件不是所述第二信息被发送时，终端设备可能在发送所述第二信息之前，就已经判断该预设条件被满足，由此，终端设备可以发送包含所述侦听结果的所述第二信息。
同理，当该预设条件不是所述第三信息被发送时，终端设备可能在发送所述第三信息之前，就已经判断该预设条件被满足，由此，终端设备可以发送包含所述侦听结果的所述第三信息。
如图3所示，终端设备在第二信息或第三信息中发送侦听结果的情况下，该通信方法还可以包括步骤221。步骤221可以包括：终端设备向网络设备发送第一指示信息，第一指示信息用于指示第二信息或第三信息中包括侦听结果。
可选地，第一指示信息可以单独发送，也可以包含在第二信息或第三信息中发送。
本申请实施例中，可选地，资源的时域起始位置与终端设备发送侦听结果的时域位置之间可以间隔特定时域长度。该特定时域长度可以为预定义的或网络设备配置的或终端设备指示的。
当该特定时域长度为预定义或网络设备配置时，网络设备已知该特定时域长度，就无需从终端设备获取。当该特定时域长度由终端设备指示时，在步骤230之前还可以包括步骤222。步骤222可以包括：终端设备向网络设备发送第四信息，第四信息用于指示该特定时域长度。
本申请实施例中，可选地，资源的时域起始位置还可以为根据特征信息确定的发送侦听结果后第一个数据包到达逻辑信道的时刻确定的。需要说明的是，该情况下，终端设备和网络设备均可根据该特征信息确定该时域起始位置。其中，该特征信息可以包括业务特征信息或业务图样信息。具体的，可以包括以下两种情况：
第一种情况，可以根据特征信息确定发送侦听结果后第一个数据包到达逻辑信道的时刻，并将该时刻作为资源的时域起始位置。
第二种情况，在第一起始位置和第二起始位置中选择时间较晚的一个作为资源的时域起始位置；其中，第一起始位置与终端设备发送侦听结果的时域位置之间间隔特定时域长度；第二起始位置为根据特征信息确定的发送侦听结果后第一个数据包到达逻辑信道的时刻。
步骤230，网络设备根据侦听结果向该终端设备发送调度信息，以使该终端设备根据调度信息向其它终端设备发送数据。
本申请实施例中，可选地，在步骤230之后，还包括步骤240。
步骤240可以包括：终端设备接收到所述调度信息之后，根据所述调度信息，向其它终端设备发送数据。
需要说明的是，网络设备可以根据侦听结果来调度终端设备，也可以根据侦听结果和其它信息来调度终端。当网络设备根据侦听结果和其它信息来调度终端时，在本申请实施例中，可选地，在步骤230之前，还可以包括步骤223。
步骤223：终端设备向网络设备发送以下至少一项：第二指示信息、第三指示信息或第四指示信息。其中，第二指示信息用于指示终端设备获取侦听结果时使用的频域资源单元；第三指示信息用于指示终端设备获取侦听结果时使用的优先级；第四指示信息用于指示终端设备获取侦听结果时使用的资源预留间隔。
终端设备获取侦听结果时使用的优先级可以是待传输数据的优先级。
包括步骤223的情况下，步骤230可以被步骤230’，步骤230’具体可以包括：网络设备根据侦听结果，以及第二指示信息、第三指示信息、第四指示信息中的至少一项向终端设备发送调度信息。
下面以车联网为例，介绍本申请的通信方法在车联网中的具体实现方式。图4是本申请实施例的一种车联网的应用场景的示意图。在图4的应用场景中，网络设备对终端设备进行调度，并将调度结果发送至该网络设备覆盖范围内的终端设备，其中，该场景下，终端设备指的是车联网中的车辆，或者终端设备还可以指车联网中处于终端角色的基础设施，或者终端设备还可以指车联网中个人携带的设备，例如，行人、骑行者、司机、乘客携带的手持设备。终端设备还可以指其他车联网中的道路使用者或道路使用者 携带的设备。
图4所示的应用场景中，终端设备之间可以进行D2D通信。第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)的版本14(Release14)定义了基于D2D链路增强的V2X链路(例如可以包括以下链路中的至少一种：V2V、V2I、V2P链路)。D2D链路和V2X链路可以采用不同的接口进行通信。
图4所示的应用场景中，终端设备与终端设备之间通信的链路可以称为侧行链路(sidelink)。
终端设备在sidelink上可以有两种资源分配的方式，一种是模式3(Mode 3)，网络设备对终端设备进行资源分配，另一种是模式4(Mode 4)，终端设备自主选择可用资源。通常，网络***中可以包括不止一个终端设备，这些终端设备中的部分终端设备采用Mode 3，其余终端设备采用Mode 4。在Mode 3中，当终端设备具有待向其它终端设备发送的数据时，终端设备可以向网络设备发送侧行链路缓存状态报告，用于向网络设备提供待向其它终端设备发送的数据量信息。该待发送数据可以包括无线链路层控制协议(Radio Link Control，RLC)层和分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层的数据。具体的，终端设备可以直接指示数据的数量。终端设备也可以指示数据数量的范围，例如，终端设备发送数据数量范围对应的索引，数据数量范围与索引的对应关系可以在标准中预先定义。但Mode 3终端设备使用的资源可以与Mode 4终端设备使用的资源重叠，网络设备并不知道Mode 4终端设备自主选择的资源，网络设备在调度Mode 3终端设备的资源时，可能会与Mode 4终端设备自主选择的资源发生碰撞。
基于此，本申请提出了一种通信方法，以避免资源发生碰撞。图5为本申请实施例提供的一种通信方法的示意***互图。应理解，图5示出了通信方法的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其他操作或者图2中的各个操作的变形。
图5所示的通信方法可以包括以下步骤。
步骤401，网络设备可以向终端设备配置频率资源数量。频率资源数量可以为子带数量。
步骤402，终端设备根据该频率资源数量确定获取侦听结果时使用的频域资源单元，或者根据该频率资源数量确定侦听结果中资源的频域单元。
步骤403，终端设备获取侧行链路资源的侦听结果，该侦听结果用于指示所述侧行链路资源的使用情况。具体的，该步骤403可以参考步骤210中的描述，步骤210中所述的资源为侧行链路资源。
其中，步骤401和步骤402为可选的，如果该方法中包括了步骤401和步骤402，则在步骤403中，终端设备根据步骤402中确定的频域资源单元或者频域单元来获取侧行链路资源的侦听结果。
步骤404，终端设备可以向网络设备发送第二指示信息，该第二指示信息用于指示频率资源数量。频率资源数量为终端设备获取所述侦听结果时使用的频域资源单元，或者为侦听结果中资源的频域单元。频率资源数量可以为子带数量。终端设备可以在上层配置的频率资源数量范围中选择一个或多个频率资源数量。
步骤405，终端设备可以向网络设备发送第三指示信息，该第三指示信息用于指示优先级。所述优先级为终端设备获取所述侦听结果时使用的优先级。该优先级可以为邻近服务包优先级(ProSe Per-Packet Priority，PPPP)。该优先级可以为终端设备待发送的传输块的优先级，或为终端设备待发送的数据所在的逻辑信道的优先级。终端设备可以根据该优先级确定阈值，所述阈值为终端设备在确定侦听结果过程中，用于和终端设备接收其他终端设备发送的参考信号的接收功率进行比较。
步骤406，终端设备可以向网络设备发送第四指示信息，该第四指示信息用于指示资源预留间隔。所述资源预留间隔为终端设备获取所述侦听结果时使用的资源预留间隔。该资源预留间隔可以为根据终端设备将要发送的业务的周期确定的。该资源预留间隔可以用于终端设备在发送一个传输块时指示其发送下一个传输块所使用的资源与本次发送之间的间隔。终端设备可以在网络配置的或预配置的资源预留周期限制范围中选择一个或多个资源预留间隔。
步骤407，若满足预设条件，则所述终端设备向网络设备发送所述侦听结果。相应地，网络设备接收该侦听结果。其中，步骤407可以具体可以参见上述步骤220中的描述，其中的资源被替换为侧行链路资源。
其中，上述步骤404-步骤406均为可选步骤，本实施例中可以包括这三个步骤中的任意一个或多个。并且本实施例不限定步骤404-步骤407这四个步骤执行的先后顺序，这四个步骤可以以任意的顺序被执行。
步骤408，网络设备根据该侦听结果向该终端设备发送调度信息，以使该终端设备根据所述调度信息向其它终端设备发送数据。
可选地，网络设备接收终端设备发送的侦听结果之后，该网络设备可以根据该侦听结果对终端设备进行调度，为该终端设备合理地分配发送数据所使用的资源，或者为该终端设备合理配置发送数据所使用的参数，如功率参数、重传次数参数、调制与编码策略(Modulation and Coding Scheme，MCS)参数等。
可选的，当本实施例中包括步骤404-步骤406中的一个或多个时，网络设备可以根据侦听结果以及终端设备在步骤404-步骤406中发送的信息来生成调度信息。本申请实施例的通信方法中，终端设备向网络设备发送侦听结果，其中，侦听结果用于指示sidelink资源的使用情况，这样，网络设备可以获得sidelink资源信息，避免发生资源碰撞，提高***的效率。
本申请实施例中，可选地，在步骤408之后，还包括步骤409。
步骤409，终端设备根据所述调度信息，向其它终端设备发送数据。
在步骤407中终端设备发送侦听结果时，实现方式可以有多种，下面结合具体的实施例进行详细描述。
可选地，作为一种实现方式，步骤407可以包括：若满足预设条件，则所述终端设备向网络设备发送包含侦听结果的sidelink BSR。如图6所示，图6是本申请实施例提供的一种包含侦听结果的sidelink BSR的示意图，该侦听结果可以包括在图6的侦听结果1中。
可选地，在该实现方式中，一个ProSe目标(destination)的一个逻辑信道组(Logical Channel Group，LCG)有一个侦听结果。Sidelink BSR中可以包括一个或多个报告目标，每个报告目标包括目标索引，LCG标识(ID)，缓存大小以及侦听结果。图6所示为一 个报告目标1，如图6所示，该报告目标1包括目标索引1，LCG ID 1，缓存大小1，侦听结果1。其中，每个报告目标中的侦听结果可以是可选的，即有的报告目标中可以没有相应的侦听结果。
可选地，在该实现方式中，该sidelink BSR或该sidelink BSR对应的子头中包括指示信息，所述指示信息用于指示所述sidelink BSR包括所述侦听结果。图7是本申请实施例提供的另一种包含侦听结果的侧行链路缓存状态报告的示意图。如图7所示，与图6相比，在该sidelink BSR中还包括指示信息I1，图7中的I1可以用于指示该sidelink BSR包括侦听结果，该侦听结果可以包括在图7的侦听结果1中，例如，当I1为1时，可以指示该sidelink BSR包括侦听结果，当I1为0时，可以指示该sidelink BSR不包括侦听结果。
可选地，可以使用该sidelink BSR对应的子头中的预留比特来指示该sidelink BSR是否包含侦听结果。例如sidelink BSR对应的子头中，R域代表预留比特。具体而言，例如，当该预留比特为0时，可以指示sidelink BSR中不包含侦听结果，当该预留比特为1时，可以指示sidelink BSR中包含侦听结果。
可选地，还可以使用该sidelink BSR对应的子头中的逻辑信道标识(Logical Channel ID，LCID)指示该sidelink BSR包含侦听结果。具体而言，LCID域的一种取值对应包含侦听结果的sidelink BSR。例如，当子头中的LCID域取值为‘10011’时，指示该子头对应包含侦听结果的sidelink BSR。LCID域的另一种取值对应不包含侦听结果的sidelink BSR。例如，当子头中的LCID域取值为‘10111’时，指示该子头对应不包含侦听结果的sidelink BSR。
上述实现方式将侦听结果承载在sidelink BSR中，无需增加额外的信令，实现简单。
可选地，作为另一种实现方式，步骤S407可以包括：若满足预设条件，则所述终端设备向网络设备发送包含侦听结果的业务特征信息或业务图样信息。
以下文示出的业务特征信息(TrafficPatternInfo)的信息格式为例，该信息格式中新增“sensingResult”字段，用于表示该终端设备向网络设备发送的侦听结果。
Figure PCTCN2018100166-appb-000001
上述实现方式将侦听结果承载在业务特征信息中，无需增加额外的信令，实现简单。
可选地，作为另一种实现方式，步骤S407可以包括：若满足预设条件，则所述终端设备向所述网络设备发送包含侦听结果的媒体接入控制控制元素(Media Access Control Control Element，MAC CE)或无线资源控制(Radio Resource Control，RRC) 消息。
本申请实施例中，可选地，sidelink资源的时域起始位置与该终端设备发送侦听结果的时域位置之间间隔特定时域长度。
可选地，上述特定时域长度为预定义的，或所述网络设备配置的，或终端设备指示的。
上述特定时域长度的取值可以根据终端设备和网络设备之间的交互和处理时延确定。作为一个示例，终端设备发送侦听结果，相应地网络设备收到该侦听结果，处理该侦听结果并向终端设备发送对应的调度授权；受交互和处理时延等因素的影响，终端设备发送侦听结果与最早可能被网络设备调度的资源中间间隔的资源不会被调度到，相应地特定时域长度可以定义或配置为大于此间隔。
例如，如图8所示，终端设备可以在子帧n向网络设备发送侦听结果。网络设备收到该侦听结果后向终端设备发送调度授权，其中，例如：网络设备处理该侦听结果并准备发送调度授权需要3个子帧，网络设备发送调度授权需要1个子帧。终端设备收到调度授权后并准备发送数据需要一些子帧，例如3个子帧，即终端设备在收到所述调度授权后的3个子帧之后，才能发送数据，如图8所示，终端设备在子帧n+i才能发送数据在该例中，i的参考取值可以为8。由此，子帧n+i以及子帧n+i之后的资源才可能被网络设备调度，即终端设备发送侦听结果与最早可能被网络设备调度的资源之间间隔为i。子帧n到子帧n+i之间的资源不会被调度到，这些资源就不必包含在该侦听结果中，因此，特定时域长度可以取不小于i的值，i为正整数。网络设备调度的资源是位于所述sidelink资源的时域起始位置之后的资源。
可选地，终端设备还可以向所述网络设备发送指示信息，所述指示信息包括或用于指示所述特定时域长度。
可选地，该特定时域长度为根据该终端设备的待发送数据包的预计到达时刻确定的，该待发送数据包的预计到达时刻可以为该待发送数据包到达终端设备的逻辑信道的时刻。终端设备下次包到达时刻前，不需要发送数据，也就不需要被调度，因此，可以将终端设备下次数据包的到达时刻与发送侦听结果之间的时域长度作为特定时域长度，或特定时域长度不小于该终端设备下次数据包的到达时刻与发送侦听结果之间的时域长度。
例如，如图9所述，终端设备可以在子帧n向网络设备发送侦听结果，该终端设备下次数据包的到达时刻为子帧n+j，因此，特定时域长度可以取不小于j的值，j为正整数。
可选地，在标准中预先定义或网络设备配置sidelink资源的时域起始位置与该终端设备发送侦听结果的时域位置之间的最小间隔。该特定时域长度可以根据该终端设备的待发送数据包的预计到达时刻以及所述最小间隔确定。具体的，该特定时域长度可以为终端设备下次数据包的到达时刻与发送侦听结果之间的间隔，与所述最小间隔中的最大值。或者，该特定时域长度可以为不小于终端设备下次数据包的到达时刻与发送侦听结果之间的间隔，与所述最小间隔中的最大值的值。例如，该特定时域长度可以取图9中的j与所述最小间隔中的最大值，或取不小于上述j和所述最小间隔中最大值的值。最小间隔可以根据终端设备和网络设备之间的交互和处理时延确定，具体类似上述特定时 域长度的取值根据终端设备和网络设备之间的交互和处理时延确定的方法，此处不再赘述。
可选地，该sidelink资源的时域起始位置为根据业务特征信息确定的发送该侦听结果后第一个数据包到达的时刻确定的。
具体地，在本申请实施例中，sidelink资源的时域起始位置还可以为根据该业务特征信息确定的发送该侦听结果后第一个数据包到达的时刻，或sidelink资源的时域起始位置为不早于根据该业务特征信息确定的发送该侦听结果后第一个数据包到达的时刻。
例如，如图10所示，终端设备向网络设备发送业务特征信息，根据业务特征信息可以确定终端设备的业务周期到达逻辑信道的时刻可以为子帧n+m和n+m+P等多个时刻。终端设备在子帧n向网络设备发送侦听结果，发送侦听结果后第一个数据包到达逻辑信道的时刻为子帧n+m，则sidelink资源的时域起始位置为子帧n+m。
可选地，在标准中预先定义或网络设备配置sidelink资源的时域起始位置与该终端设备发送侦听结果的时域位置之间的最小间隔。该sidelink资源的时域起始位置可以根据该业务特征信息确定的发送该侦听结果后第一个数据包到达的时刻，以及所述最小间隔确定。具体的，该sidelink资源的时域起始位置可以为根据该业务特征信息确定的发送该侦听结果后第一个数据包到达的时刻，和与发送该侦听结果间隔所述最小间隔的时刻中的最大值。例如，该sidelink资源的时域起始位置可以取图10中的子帧n+m和与子帧n间隔所述最小间隔的时刻中的最大值。最小间隔可以根据终端设备和网络设备之间的交互和处理时延确定，具体类似上述特定时域长度的取值根据终端设备和网络设备之间的交互和处理时延确定的方法，此处不再赘述。
在本申请实施例中，可选地，终端设备向网络设备发送指示信息，所述指示信息用于指示业务特征信息或业务图样信息列表的索引。终端设备获取所述侦听结果时使用的周期、优先级等参数为所述索引标识的业务特征信息或业务图样信息中的周期、优先级等参数。或者，所述sidelink资源的起始时域位置为根据所述索引标识的业务特征信息或业务图样信息确定的发送该侦听结果后第一个数据包到达的时刻确定的。由于终端设备可以向网络设备发送业务特征信息列表，该列表包含多个业务特征信息，因此，每个业务特征信息可以通过其在该列表中的索引被识别。
在本申请实施例中，可选地，所述sidelink资源的时域结束位置与终端设备发送侦听结果之间的间隔不超过参数M，且需要满足将要发送的数据的时延要求。其中，M为大于0的整数，例如，M＝100。在实际应用中M的值可以根据V2X业务的周期或者根据终端设备资源预留的间隔而定。例如，终端设备V2X业务的周期为20ms，则M为20。所述sidelink资源的时域结束位置需要满足将要发送的数据的时延要求，可以理解为sidelink资源的时域结束位置不晚于终端设备将要发送的数据包到时刻间隔最大时延的时刻。
