在SL通信系统中，一个终端设备抢占到传输机会(transmission opportunity，TXOP)之后，该终端设备可以发起信道占用时间(channel occupancy time，COT)分享(share)，即该终端设备可以将TXOP内的一个或多个梳齿分配给其他终端设备。然而，终端设备如何为其他终端设备分配TXOP内的一个或多个梳齿的问题还未解决。并且，当终端设备自身也存在传输需求时，如何将TXOP内的一个或多个梳齿分配给其他终端设备和本设备，也是需要解决的问题之一。
发明内容
本申请实施例提供一种资源分配方法及装置，以期解决终端设备如何为终端设备进行的传输和/或其他终端设备分配梳齿问题。
第一方面，提供了一种资源分配方法，该方法可以由终端设备执行，或者，也可以由终端设备的组成部件(例如芯片或者电路)执行，对此不作限定，为了便于描述，下面以由第一终端设备执行为例进行说明。
该方法可以包括：第一终端设备根据第一信息确定为N个传输分配的至少一个梳齿，该N个传输中的每个传输占用该至少一个梳齿中的一个或多个，该第一信息包括至少一个第二终端设备发送的参考信号的强度，N为正整数；其中，该N个传输包括该第一终端设备对应的传输，该第一终端设备在该至少一个梳齿上发送该N个传输；或者，该N个传输包括该至少一个第二终端设备对应的传输，该第一终端设备向该至少一个第二终端设备发送资源分配信息，该资源分配信息用于指示为该至少一个第二终端设备对应的传输分配的梳齿。
基于上述技术方案，第一终端设备可以根据至少一个第二终端设备发送的参考信号的强度，为N个传输分配梳齿，从而可以避免至少一个梳齿的梳齿间干扰过大，或者，可以避免第一终端设备为N个传输中的每个传输分配的梳齿的干扰过大。
例如，在N个传输包括至少一个第二终端设备对应的传输的情况下，第一终端设备根据至少一个第二终端设备发送的参考信号为N个传输分配梳齿的过程中，若N个传输中的两个传输分别对应的信号强度过大，则第一终端设备为该两个传输分配的梳齿不相邻，从而可以有效减小两个传输之间的互相干扰。
又例如，在N个传输包括第一终端设备对应的传输的情况下，第一终端设备根据至少一个第二终端设备发送的参考信号为N个传输分配梳齿的过程中，若预约了某个梳齿的第二终端设备发送的参考信号的强度过大，则第一终端设备不为N个传输分配该梳齿，从而可以避免第一终端设备为N个传输中的每个传输分配的梳齿的干扰过大。
结合第一方面，在第一方面的某些实现方式中，该第一信息还包括该第一终端设备发送的参考信号的强度。
基于上述技术方案，在N个传输包括第一终端设备对应的传输的情况下，第一终端设备根据第一终端设备发送的参考信号的强度为N个传输分配至少一个梳齿，可以避免至少一个梳齿的梳齿间干扰过大。例如，若N个传输中的两个传输分别对应的接收端测量第一终端设备发送的参考信号得到的信号强度过大，则第一终端设备为该两个传输分配的梳齿不相邻，从而可以有效减少两个传输之间的互相干扰。
结合第一方面，在第一方面的某些实现方式中，该第一终端设备根据第一信息确定为N个传输分配的至少一个梳齿，包括：该第一终端设备根据该第一信息，确定分配给该N个传输中的第一传输的第一梳齿，该第一梳齿满足第一条件，该第一条件包括以下一项或多项：第一信号强度和/或第二信号强度不超过第一门限值；该第一信号强度与该第二信号强度的差值小于第二门限值，或，该第二信号强度与该第一信号强度的差值小于该第二门限值；该第一信号强度与该第二信号强度的比值不超过第三门限值，或，该第二信号强度与该第一信号强度的比值不超过该第三门限值；与该第一梳齿相邻的梳齿还未分配给该N个传输中的传输；该至少一个第二终端设备均未预约该第一梳齿；或者，该至少一个第二终端设备中，预约了该第一梳齿的终端设备发送的参考信号的信号强度不超过第四门限值；该至少一个第二终端设备均未预约第二梳齿；或者，该至少一个第二终端设备中，预约了该第二梳齿的终端设备发送的参考信号的信号强度不超过第五门限值；其中，该第一信号强度是该第一传输对应的终端设备发送的参考信号的强度，该第二信号强度是该N个传输中的第二传输对应的终端设备发送的参考信号的强度，该第二传输由该第一终端设备分配的梳齿是第二梳齿，该第二梳齿与该第一梳齿相邻。
基于上述技术方案，第一梳齿满足第一条件的情况下，可以避免第一传输对其他传输造成的干扰过大，和/或，避免其他传输对第一传输造成的干扰过大。例如，在第一条件包括第一信号强度和第二信号强度不超过第一门限值的情况下，基于第一条件，由于第一信号强度不超过第一门限值，因此可以避免第一传输对其余传输造成的干扰过大，并且，在第一梳齿与第二梳齿相邻的情况下，第二梳齿上的第二传输对应的第二信号强度也不超过第一门限值，因此可以避免第二传输对第一传输的造成的干扰过大。
结合第一方面，在第一方面的某些实现方式中，以下一个或多个门限值与该第二传输的优先级有关：该第一门限值、该第二门限值、该第三门限值。
结合第一方面，在第一方面的某些实现方式中，若该第一终端设备已为该N个传输中的第三传输分配第三梳齿，该第三梳齿与该第一梳齿间隔k个梳齿，k为正整数，则该第一条件还包括：该第一信号强度小于第六门限值，或，该第一信号强度与第一干扰泄漏参数的乘积小于第七门限值；其中，该第一干扰泄漏参数用于确定该第一传输对应的终端设备产生的干扰泄漏。
基于上述技术方案，在第一条件包括上述条件的情况下，若第一梳齿满足第一条件，则可以避免第一传输对第三传输造成的干扰过大。
结合第一方面，在第一方面的某些实现方式中，该第六门限值或该第七门限值与k的值和/或第三信号强度相关，该第三信号强度是该第三传输对应的终端设备发送的参考信号的强度。
可选的，第一条件还可以包括：该第三信号强度小于第六门限值，或，该第三信号强度与第一干扰泄漏参数的乘积小于第七门限值。
基于上述技术方案，在第一条件包括上述条件的情况下，若第一梳齿满足第一条件，则可以避免第三传输对第一传输造成的干扰过大。
结合第一方面，在第一方面的某些实现方式中，该第一条件还包括：如果该第一终端设备已为该N个传输中的L个传输分配了梳齿，且该第一终端设备将该第一梳齿分配给该第一传输之后，则L+1个传输中的第l个传输受到的干扰总和不超过第八门限值，该L+1个传输包括该L个传输和该第一传输，l和L为正整数，1≤l≤L+1。
基于上述技术方案，在第一条件包括上述条件的情况下，若第一梳齿满足第一条件，则第一终端设备为第一传输分配第一梳齿之后，每个梳齿上受到的干扰总和不超过第八门限值，从而可以进一步避免至少一个梳齿的梳齿间干扰过大。

基于上述技术方案，在第一条件包括上述条件的情况下，若第一梳齿满足第一条件，则第一传输的接收端与第三传输的发送端之间的距离较大，从而可以避免第三传输对第一传输的干扰过大，和/或，第一传输的发送端与第三传输的接收端之间的距离较大，从而可以避免第一传输对第三传输的干扰过大。
结合第一方面，在第一方面的某些实现方式中，该第九门限值与以下一项或多项相关：该第二传输的优先级，该第一信号强度，第三信号强度，该第一传输的优先级，k的值，该第三信号强度是该第三传输对应的终端设备发送的参考信号的强度。

基于上述技术方案，第一终端设备优先为距离最近的两个传输分配梳齿，有利于实现为距离最近的两个传输分配的梳齿不相邻，从而可以避免距离最近的两个传输由于距离太近而导致的干扰过大。
结合第一方面，在第一方面的某些实现方式中，该N个传输包括该至少一个第二终端设备对应的传输，该至少一个第二终端设备对应的传输包括以该第一终端设备为接收端的第四传输，该方法还包括：该第一终端设备确定优先为该第四传输分配梳齿。

基于上述技术方案，可以保证与第四梳齿相邻的梳齿空闲，或者，与第四梳齿相邻的梳齿上的传输是N个传输中未被分配梳齿的传输中信号强度最小的传输，从而可以避免其余传输对第四传输造成太大的干扰，以及可以保证第四传输的传输性能。其中，传输的信号强度指的是传输对应的终端设备发送的参考信号的强度。
结合第一方面，在第一方面的某些实现方式中，该第一条件还包括以下一项或多项：若该N个传输占用的梳齿的总数小于可分配的梳齿的数量，则由该第一终端设备为该第四传输分配的第四梳齿与该第一梳齿至少间隔一个梳齿；若该N个传输占用的梳齿总数等于可分配的梳齿的数量，且该第一梳齿与该第四梳齿相邻，则该第一传输与第四传输之间的距离不低于第十三门限值。

基于上述技术方案，可以保证与第四梳齿相邻的梳齿空闲，或者，与第四梳齿相邻的梳齿上的传输与第四传输之间的距离较远，从而可以避免其余传输对第四传输造成太大的干扰，以及可以保证第四传输的传输性能。其中，传输的信号强度指的是传输对应的终端设备发送的参考信号的强度。
结合第一方面，在第一方面的某些实现方式中，该N个传输包括该至少一个第二终端设备对应的传输，该第一信息还包括该N个传输中每个传输的优先级，该方法还包括：该第一终端设备根据该第一信息，确定优先为该N个传输中的第五传输分配梳齿，该第五传输是该N个传输中优先级最高的传输。

基于上述技术方案，可以保证与第五梳齿相邻的梳齿空闲，或者，与第五梳齿相邻的梳齿上的传输是N个传输中未被分配梳齿的传输中信号强度最小的传输，从而可以避免其余传输对第五传输造成太大的干扰，以及可以保证第五传输的传输性能。
结合第一方面，在第一方面的某些实现方式中，该第一条件还包括以下一项或多项：若该N个传输占用的梳齿的总数小于可分配的梳齿的数量，则由该第一终端设备为该第五传输分配的第五梳齿与该第一梳齿至少间隔一个梳齿；若该N个传输占用的梳齿总数等于可分配的梳齿的数量，且该第一梳齿与该第五梳齿相邻，则该第一传输与第五传输之间的距离不低于第十四门限值。

下面将结合附图，对本申请实施例中的技术方案进行描述。
本申请提供的技术方案可以应用于各种通信系统，例如：第五代(5th generation，5G)或新无线(new radio，NR)系统、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)系统等。本申请提供的技术方案还可以应用于未来的通信系统，如第六代移动通信系统。本申请提供的技术方案还可以应用于设备到设备(device to device，D2D)通信，车到万物(vehicle-to-everything，V2X)通信，机器到机器(machine to machine，M2M)通信，机器类型通信(machine type communication，MTC)，以及物联网(internet of things，IoT)通信系统或者其他通信系统。作为示例，V2X可包括车辆到车辆(vehicle-to-vehicle，V2V)，车辆到行人(vehicle-to-pedestrian，V2P)，车辆到基础设施(vehicle-to-infrastructure，V2I)。其中，基础设施例如为路侧单元(road side unit，RSU)或者网络设备。
本申请实施例中的终端设备包括各种具有无线通信功能的设备，其可用于连接人、物、机器等。终端设备可以广泛应用于各种场景，例如：蜂窝通信，D2D，V2X，端到端(peer to peer，P2P)，M2M，MTC，IoT，虚拟现实(virtual reality，VR)，增强现实(augmented reality，AR)，工业控制，自动驾驶，远程医疗，智能电网，智能家具，智能办公，智能穿戴，智能交通，智慧城市无人机，机器人，遥感，被动传感，定位，导航与跟踪，自主交付等场景。终端设备可以是上述任一场景下的终端，如MTC终端、IoT终端等。终端设备可以是第三代合作伙伴项目(3rd generation partnership project，3GPP)标准的用户设备(user equipment，UE)、终端(terminal)、固定设备、移动台(mobile station)设备或者说移动设备、用户单元(subscriber unit)、手持设备、车载设备、可穿戴设备、蜂窝电话(cellular phone)、智能电话(smart phone)、SIP电话、无线数据卡、个人数字助理(personal digital assistant，PDA)、电脑、平板电脑、笔记本电脑、无线调制解调器、手持设备(handset)、膝上型电脑(laptop computer)、具有无线收发功能的计算机、智能书、车辆、卫星、全球定位系统(globalpositioning system，GPS)设备、目标跟踪设备、飞行器(例如无人机、直升机、多直升机、四直升机、或飞机等)、船只、遥控设备智能家居设备、工业设备，或者内置于上述设备中的装置(例如，上述设备中的通信模块、调制解调器或芯片等)，或者连接到无线调制解调器的其它处理设备。
应理解，在某些场景下，终端设备还可以用于充当基站。例如，终端设备可以充当调度实体，其在V2X、D2D或P2P等场景中的终端设备之间提供侧行链路信号。
本申请实施例中，用于实现终端设备的功能的装置，也即终端装置，可以是终端设备，也可以是能够支持终端设备实现该功能的装置，例如芯片系统或芯片，该装置可以被安装在终端设备中。本申请实施例中，芯片系统可以由芯片构成，也可以包括芯片和其他分立器件。
终端设备可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和卫星上。本申请实施例中对终端设备所处的场景不做限定。
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和b，a和c，b和c，或a和b和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，“示例性地”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“示例性地”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“示例性地”或者“例如”等词旨在以具体方式呈现相关概念，便于理解。
此外，本申请实施例描述的网络架构以及业务场景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和新业务场景的出现，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。
图1示出了适用于本申请一实施例的无线通信系统的示意图。如图1所示，该无线通信系统可以包括至少三个终端设备，例如图1所示的终端设备110、终端设备120和终端设备130。终端设备与终端设备之间直接通信的链路可称为侧行链路(sidelink，SL)，终端设备与终端设备之间的直接通信可称为SL通信。
应理解，图中仅为示意，示出了三个终端设备之间的SL链路，但这不应对本申请构成任何限定。在该通信系统中，还可以包括更多数量的终端设备，终端设备之间的通信链路均可以称为SL链路。
无线通信系统使用的频谱分为两类，授权频谱(licensed spectrum)和非授权频谱(unlicensed spectrum)。在授权频谱中，终端设备可基于网络设备的调度使用频谱资源进行SL通信。在非授权频谱中，终端设备可按照竞争的方式使用频谱资源进行SL通信。一种可能的方式，终端设备通过先听后说(listen-before-talk，LBT)的方式竞争信道，进而使用信道资源进行SL通信。
在NR中，为了满足对非授权频谱的信道占用要求，频域资源分配以梳齿(interlace)为一个单位，一个梳齿由等间隔离散分布的整数个频域单元组成，如图2所示，一个梳齿可以包括物理资源块(physical resource block，PRB)20、PRB45、PRB70和PRB95，该四个PRB中任意两个相邻的PRB等间隔分布，即间隔25个PRB。在以梳齿为一个单位分配频域资源的情况下，可以实现发送设备在20 MHz带宽内占用的最低频域位置和最高频域位置之间的频域资源占用80％的频带，从而既满足了非授权频谱的信道占用要求，又不用实际占用80％的频带。
需要说明的是，图2以梳齿包括的任意两个相邻的PRB之间的间隔是25个PRB为例，本申请实施例并不限定梳齿包括的任意两个相邻的PRB之间的间隔。例如，在子载波间隔(subcarrier space，SCS)为15 KHz的情况下，一个梳齿包括的任意两个相邻的PRB之间间隔10个PRB，例如，一个梳齿可以包括PRB0、PRB10、PRB 20、……、PRB100。又例如，在SCS为30 KHz的情况下，一个梳齿包括的任意两个相邻的PRB之间间隔5个PRB，例如，一个梳齿可以包括PRB0、PRB5、PRB15、……、PRB50。
另外，本申请中“梳齿”也可以称为“交错”、“交织”、“频域单元组”等，本申请对于梳齿的名称不做限定。频域单元例如可以包括但不限于，子带(subband)、资源块(resource block，RB)、资源块组(resource block group，RBG)、预编码资源块组(precoding resource block group，PRG)等。
在SL通信系统中，一个终端设备抢占到传输机会(transmission opportunity，TXOP)之后，该终端设备可以发起信道占用时间(channel occupancy time，COT)分享(share)，即该终端设备可以将TXOP内的一个或多个梳齿分配给其他终端设备。然而，终端设备如何为其他终端设备分配TXOP内的一个或多个梳齿的问题还未解决。并且，当终端设备自身也存在传输需求时，如何将TXOP内的一个或多个梳齿分配给其他终端设备和本设备，也是需要解决的问题之一。
有鉴于此，本申请实施例提供一种资源分配的方法，以实现终端设备为其他终端设备和/或该终端设备本身分配用于进行传输的梳齿。
下文将结合附图详细说明本申请实施例提供的方法。本申请提供的实施例可以应用于上述图1所示的网络架构中，不作限定。
图3示出了本申请实施例提供的资源分配方法300的示意性流程图，该方法300可以包括如下步骤。

可以理解，预约消息包括上述信息的情况下，第一终端设备接收到来自第二终端设备的预约消息之后，可以解析预约消息，并获取预约消息包括的上述信息。
示例性的，预约消息用于预约第二终端设备用于进行一个传输的梳齿，或者，预约消息用于预约第二终端设备用于进行多个传输的梳齿。例如，预约消息用于预约第二终端设备用于进行传输#A的梳齿，或者，预约消息用于预约第二终端设备用于进行传输#A和传输#B的梳齿。
在预约消息用于预约第二终端设备用于进行多个传输的梳齿的情况下，预约消息可以包括与该多个传输中的每个传输分别对应的信息。例如，多个传输包括传输#A和传输#B，预约消息可以包括以下一项或多项：第二终端设备进行传输#A的时间信息，第二终端设备进行传输#B的时间信息，第二终端设备预约的用于进行传输#A的梳齿的数量，第二终端设备预约的用于进行传输#B的梳齿的数量，传输#A的优先级，传输#B的优先级，传输#A的数据量，传输#B的数据量，传输#A的吞吐量，传输#B的吞吐量，第二终端设备的位置信息，传输#A的对端设备的位置信息，传输#B的对端设备的位置信息。
需要说明的是，方法300仅以第一终端设备接收到来自一个第二终端设备的预约消息为例，在S310中，第一终端设备可以接收到来自多个第二终端设备的预约消息。
还需要说明的是，S310是可选的步骤。
在一种可能的实现方式中，第一终端设备可以根据第一终端设备的传输需求，确定第二终端设备的传输需求。例如，第二终端设备进行的传输是以第一终端设备为接收端的传输，则第一终端设备可以根据第一终端设备接收传输所需的梳齿或资源，确定第二终端设备进行传输所需的梳齿或资源。
在另一种可能的实现方式中，第一终端设备在进行方法300之前，已经接收到来自第二终端设备的预约消息，则方法300不再执行S310。
可选的，在S310中，第一终端设备还可以接收到来自第四终端设备的预约消息，第四终端设备用于预约第四终端设备进行传输的梳齿或资源。
可选的，方法300还包括S320。
S320，第三终端设备向第一终端设备发送第二信息。
相应的，在S320中，第一终端设备接收来自第三终端设备的第二信息。
第二信息包括以下一项或多项：至少一个第二终端设备发送的参考信号的强度，至少一个第二终端设备发送的参考信号的强度的排序，第一终端设备发送的参考信号的强度。
其中，第二终端设备发送的参考信号的强度是第三终端设备测量第二终端设备发送的参考信号得到的，第二终端设备发送的参考信号的强度可以用参考信号接收功率(reference signal receiving power，RSRP)或接收信号的强度指示(receiving signal strength indicator，RSSI)表示。下文中为便于描述，将第二终端设备发送的参考信号的强度记为第二终端设备的信号强度。
若第三终端设备检测到多个第二终端设备发送的参考信号，则第二信息还可以包括多个第二终端设备的信号强度的排序。多个第二终端设备的信号强度的排序可以是从大到小的排序，也可以是从小到大的排序。

S330，第一终端设备获取传输机会。
本申请实施例对第一终端设备获取传输机会的方式不做限定。
示例性的，第一终端设备通过LBT的方式竞争信道，进而获取到传输机会。LBT是一种基于随机退避(random back-off)的信道接入规则。第一终端设备在接入信道之前，先感知(sense)信道是否空闲(idle)。如果信道已经保持空闲一定时间则第一终端设备可以占用信道，如果信道非空闲则需要等待信道恢复为空闲后才可以占用信道。一种可能的实现方式，第一终端设备采用基于能量的检测和信号类型的检测，来确定信道是否空闲。以能量的检测为例，当第一终端设备检测的能量超过检测门限时，判决为信道忙，也即不允许接入信道。当第一终端设备检测的能量低于检测门限，且持续超过一段时间，判决为信道空闲，也即允许接入信道。
需要说明的是，第一终端设备可以通过其他方式获取传输机会，本申请实施例对此不做限定。
还需要说明的是，S330是可选的步骤。
在一种可能的实现方式中，第一终端设备执行方法300之前，已经获取到了传输机会，则方法300不再执行S330。S340，第一终端设备根据第一信息确定为N个传输分配至少一个梳齿。
N个传输包括至少一个第二终端设备对应的传输，N个传输中的每个传输占用至少一个梳齿中的一个或多个梳齿，并且N个传输中的不同传输占用不同的梳齿，N为正整数。第一终端设备获取到的传输机会包括该至少一个梳齿。
可选的，N个传输还包括第一终端设备发送的传输。

例如，若第一终端设备接收到一个第二信息，且该第二信息包括第二终端设备的信号强度，则第一终端设备从第二信息中获取到第二终端设备的信号强度。又例如，若第一终端设备接收到多个第二信息，该多个第二信息中每个第二信息都包括第二终端设备的信号强度，则第一终端设备根据该多个第二信息确定，第一信息包括的第二终端设备的信号强度是多个第二信息包括的第二终端设备的信号强度的平均值。又例如，若第一终端设备接收到第二终端设备发送的参考信号，并且第一终端设备接收到第二信息，则第一终端设备确定第一信息包括的第二终端设备的信号强度，是第一终端设备测量第二终端设备发送的参考信号得到的信号强度与第二信息包括的第二终端设备的信号强度的平均值。
可选的，第一信息还包括第一终端设备的信号强度。第一终端设备的信号强度是第一终端设备根据接收到的第二信息确定的。例如，若第一终端设备接收到一个第二信息，且该第二信息包括第一终端设备的信号强度，则第一终端设备从第二信息中获取到第一终端设备的信号强度。又例如，若第一终端设备接收到多个第二信息，该多个第二信息中每个第二信息都包括第一终端设备的信号强度，则第一终端设备根据该多个第二信息确定，第一信息包括的第一终端设备的信号强度是多个第二信息包括的第一终端设备的信号强度的平均值。
可选的，第一信息还包括至少一个第二终端设备的位置信息和至少一个第二终端设备进行的传输的对端设备的位置信息。下文中为便于描述，将第二终端设备进行的传输的对端设备记为第二终端设备的对端设备。
至少一个第二终端设备的位置信息和/或至少一个第二终端设备的对端设备的位置信息预配置在第一终端设备中，或者，是第一终端设备从接收到的预约消息中获取的。
可选的，第一信息还包括第一终端设备的位置信息和第一终端设备进行的传输的对端设备的位置 信息。下文中为便于描述，将第一终端设备进行的传输的对端设备记为第一终端设备的对端设备。
第一终端设备的位置信息和/或第一终端设备的对端设备的位置信息预配置在第一终端设备中，或者，是第一终端设备从接收到的第二信息中获取的，或者是第一终端设备从接收到的高层信息中获取的。
可选的，第一信息还包括N个传输中每个传输的优先级。N个传输中每个传输的优先级预配置在第一终端设备中，或者，是第一终端设备从接收到的预约消息中获取的。
可选的，第一信息还包括N个传输中每个传输对应的终端设备预约的梳齿的数量。以N个传输中的第一传输为例，第一传输对应的终端设备预约的梳齿的数量指的是第一传输对应的终端设备预约的用于进行第一传输的梳齿的数量。如前所述，N个传输包括第二终端设备对应的传输，因此第一终端设备可以从接收到的预约消息中获取第二终端设备预约的梳齿的数量。
可选的，第一信息还包括N个传输中每个传输的吞吐量。N个传输中每个传输的吞吐量是第一终端设备从接收到的预约消息中获取的，或者，是第一终端设备根据接收到的预约消息确定的。以N个传输中的第一传输为例，若第一终端设备接收到的预约消息包括第一传输的数据量，则第一传输的吞吐量可以是根据第一传输的数据量确定的。
下面以第一终端设备为N个传输中的第一传输分配梳齿为例，说明第一终端设备如何根据第一信息为N个传输分配至少一个梳齿。
第一终端设备根据第一信息确定分配给第一传输的第一梳齿满足第一条件。
示例性的，若第一信息包括第二终端设备的信号强度，则第一条件包括以下一项或多项：条件#1，第一信号强度不超过第一门限值；条件#2，第二信号强度不超过第一门限值；条件#3，第一信号强度与第二信号强度的差值不超过第二门限值，和/或，第二信号强度与第一信号强度的差值不超过第二门限值；条件#4，第一信号强度与第二信号强度的比值不超过第三门限值，和/或，第二信号强度与第一信号强度的比值不超过第三门限值；条件#5，与第一梳齿相邻的梳齿还未分配给N个传输中的传输；条件#6，至少一个第二终端设备均未预约第一梳齿；条件#7，至少一个第二终端设备中预约了第一梳齿的第二终端设备的信号强度不超过第四门限值；条件#8，至少一个第二终端设备均未预约第二梳齿；条件#9，至少一个第二终端设备中预约了第二梳齿的第二终端设备的信号强度不超过第五门限值。
其中，第一信号强度是第一传输对应的终端设备发送的参考信号的信号强度，第二信号强度是N个传输中的第二传输对应的终端设备发送的参考信号的信号强度，第二传输由第一终端设备分配的梳齿是第二梳齿，第二梳齿与第一梳齿相邻。至少一个第二终端设备中的每个第二终端设备都发送了预约消息，或者说，第一终端设备接收到来自至少一个第二终端设备中每个第二终端设备的预约消息。
条件#3还可以表示为：max(第一信号强度，第二信号强度)-min(第一信号强度，第二信号强度)≤第二门限值。条件#4还可以表示为：max(第一信号强度，第二信号强度)/min(第一信号强度，第二信号强度)≤第三门限值，或者，条件#4可以表示为：min(第一信号强度，第二信号强度)/max(第一信号强度，第二信号强度)＞1/第三门限值。
需要说明的是，在第一终端设备为第一传输分配第一梳齿的过程中，若与第一梳齿相邻的第二梳齿还未分配给第二传输，则第一终端设备可以直接确定第一梳齿满足条件#3和/或条件#4。也就是说，第一终端设备可以在不判断第一信号强度与第二信号强度的差值与第二门限值之间的关系的情况下，确定第一梳齿满足条件#3。第一终端设备也可以在不判断第一信号强度与第二信号强度的比值与第三门限值之间的关系的情况下，确定第一梳齿满足条件#4。
可选的，第一条件包括条件#1的情况下，若与第一梳齿相邻的第二梳齿已被分配给第二传输，或者，与第一梳齿相邻的梳齿即将被分配给第二传输，则第一梳齿需要满足条件#1。换句话说，若第二梳齿已被分配给第二传输，则第一信号强度不超过第一门限值的情况下，第一终端设备可以将与第二梳齿相邻的梳齿作为第一梳齿分配给第一传输。或者，若与第一梳齿相邻的梳齿即将被分配给第二传输，则在第一信号强度不超过第一门限值的情况下，第一终端设备可以将第一梳齿分配给第一传输。若与第一梳齿相邻的梳齿可以保持空闲，则即使第一信号强度超过第一门限值，第一终端设备也可以将第一梳齿分配给第一传输。
可选的，若第一传输是第二终端设备向第一终端设备发送的传输，或者，第一传输是N个传输中优先级最高的传输，则第一条件包括条件#6至条件#9中的一项或多项。
可选的，第一门限值至第五门限值中的一个或多个，是协议预定义的值或者标准预定义的值。
可选的，第一门限值至第五门限值中的一个或多个是固定值，或者是可变的值。例如，第一门限值至第三门限值中的一个或多个与第二传输的优先级相关。例如，第二传输的优先级越高，与第二传输的优先级相关的门限值越小。又例如，第四门限值与第一传输的优先级(记为优先级#1)和预约第一梳齿的终端设备进行的传输的优先级(记为优先级#2)相关，例如第四门限值可以表示为min(优先级#1对应的信号强度门限值，优先级#2对应的信号强度门限值)。又例如，第五门限值与第一传输的优先级相关，第一传输的优先级越高，第五门限值越小。
根据上述第一条件可知，第一终端设备首先为第一传输分配梳齿的情况下，若某个梳齿满足条件#1、条件#6至条件#9中的一项或多项，则第一终端设备可以将该梳齿分配给第一传输，或者说第一终端设备确定第一梳齿可以包括该梳齿。
如图4所示，在子载波间隔(subcarrier space，SCS)为30 KHz的情况下，第一终端设备获取的传输机会包括的可分配的梳齿数量为5个，即图4所示的梳齿0至梳齿4。如图4中的(a)所示，假设第一终端设备根据接收到的预约消息确定UE2(第二终端设备的一例)预约了梳齿0，以及确定UE3(第二终端设备的一例)预约了梳齿4。
在第一条件包括条件#1的情况下，若第一信号强度不超过第一门限值，则梳齿0至梳齿4均满足第一条件，进而第一终端设备确定第一梳齿包括梳齿0至梳齿4中的一个或多个。
可选的，若N个传输占用的梳齿的数量不超过3个，则与第一梳齿相邻的两个梳齿可以保持空闲，进而即使第一信号强度超过第一门限值，第一终端设备也可以将梳齿0至梳齿4中一个或多个分配给第一传输。若N个传输占用的梳齿的数量为4个，则与第一传输相邻的一个梳齿会被分配给N个传输中的传输，或者，若N个传输占用的梳齿的数量为5个，则与第一传输相邻的两个梳齿都会被分配给N个传输中的传输，进而若第一信号强度不超过第一门限值，则梳齿0至梳齿4均满足第一条件。
在第一条件包括条件#6的情况下，梳齿1至梳齿3均满足第一条件，进而第一终端设备确定第一梳齿包括梳齿1至梳齿3中的一个或多个。
在第一条件包括条件#7的情况下，由于至少一个第二终端设备均未预约梳齿1至梳齿3，因此梳齿1至梳齿3均满足第一条件。假设UE2的信号强度超过第四门限值，则梳齿0不满足第一条件，假设UE3的信号强度不超过第四门限值，则梳齿4满足第一条件，进而第一终端设备确定第一梳齿包括梳齿1至梳齿4中的一个或多个。
在第一条件包括条件#8的情况下，由于梳齿2与梳齿0和梳齿4不相邻，因此梳齿2满足第一条件，进而第一终端设备确定第一梳齿包括梳齿2。
在第一条件包括条件#9的情况下，由于梳齿2不与梳齿0和梳齿4相邻，因此梳齿2满足第一条件。假设UE2的信号强度超过第五门限值，则与梳齿0相邻的梳齿1和梳齿4不满足第一条件。假设UE3的信号强度不超过第五门限值，则与梳齿4相邻的梳齿0和梳齿3满足第一条件。进而第一终端设备确定第一梳齿包括梳齿0、梳齿2和梳齿3中的一个或多个。
根据上述第一条件可知，若第一终端设备为第一传输分配梳齿之前，为第二传输分配了第二梳齿，则某个梳齿满足条件#1至条件#9中的一项或多项的情况下，第一终端设备可以将该梳齿分配给第一传输，或者说第一终端设备确定第一梳齿可以包括该梳齿。
如图4中的(b)所示，假设第一终端设备为第一传输分配梳齿之前，已将梳齿1分配给UE4(第二终端设备的一例)，假设第一终端设备根据接收到的预约消息确定UE2(第二终端设备的一例)预约了梳齿0，以及确定UE3(第二终端设备的一例)预约了梳齿4。
在第一条件包括条件#1的情况下，若第一信号强度不超过第一门限值，则梳齿0、梳齿2至梳齿4满足第一条件，进而第一终端设备确定第一梳齿包括梳齿0、梳齿2至梳齿4中的一个或多个。
可选的，对于与梳齿1相邻的梳齿0和梳齿2，若第一信号强度不超过第一门限值，则梳齿0和梳齿2满足第一条件。对于与梳齿1不相邻的梳齿3，若与梳齿3相邻的两个梳齿可以保持空闲，则不论第一信号强度是否超过第一门限值，梳齿3都可以作为第一梳齿分配给第一传输；若与梳齿3相邻的一个梳齿或两个梳齿即将被分配给其他传输，则第一信号强度不超过第一门限值的情况下，梳齿3满足第一条件。对于与梳齿1不相邻的梳齿4，若与梳齿4相邻的两个梳齿可以保持空闲，则不论第一信号强度是否超过第一门限值，梳齿4都可以作为第一梳齿分配给第一传输；若与梳齿4相邻的一个梳 齿或两个梳齿即将被分配给其他传输，则第一信号强度不超过第一门限值的情况下，梳齿4满足第一条件。
在第一条件包括条件#2的情况下，由于与梳齿3相邻的两个梳齿都未分配给其他传输，因此可以认为与梳齿3相邻的两个梳齿上的信号强度为0(不超过第一门限值)，也就是说梳齿3满足第一条件。类似的，梳齿4也满足第一条件。对于与梳齿1相邻的梳齿0和梳齿2，若UE4的信号强度(第二信号强度的一例)不超过第一门限值，则梳齿0和梳齿2也满足第一条件。若UE4的信号强度超过第一门限值，则梳齿0和梳齿2不满足第一条件。进而第一终端设备确定第一梳齿包括满足第一条件的梳齿中的一个或多个梳齿。
在第一条件包括条件#3的情况下，由于与梳齿3相邻的两个梳齿都未分配给其他传输，因此第一终端设备可以确定梳齿3满足第一条件。类似的，梳齿4也满足第一条件。对于与梳齿1相邻的梳齿0和梳齿2，若UE4的信号强度与第一信号强度的差值不超过第二门限值，和/或，第一信号强度与UE4的信号强度的差值不超过第二门限值，则梳齿0和梳齿2也满足第一条件。若UE4的信号强度与第一信号强度的差值超过第二门限值，和/或，第一信号强度与UE4的信号强度的差值超过第二门限值，则梳齿0和梳齿2不满足第一条件。进而第一终端设备确定第一梳齿包括满足第一条件的梳齿中的一个或多个梳齿。
在第一条件包括条件#4的情况下，由于与梳齿3相邻的两个梳齿都未分配给其他传输，因此第一终端设备可以确定梳齿3满足第一条件。类似的，梳齿4也满足第一条件。对于与梳齿1相邻的梳齿0和梳齿4，若UE4的信号强度与第一信号强度的比值不超过第三门限值，和/或，第一信号强度与UE4的信号强度的比值不超过第三门限值，则梳齿0和梳齿2也满足第一条件。若UE4的信号强度与第一信号强度的比值超过第三门限值，和/或，第一信号强度与UE4的信号强度的比值超过第三门限值，则梳齿0和梳齿2不满足第一条件。进而第一终端设备确定第一梳齿包括满足第一条件的梳齿中的一个或多个梳齿。
在第一条件包括条件#5的情况下，与梳齿1不相邻的梳齿3和梳齿4均满足第一条件，而与梳齿1相邻的梳齿0和梳齿2不满足第一条件，进而第一终端设备确定第一梳齿包括梳齿3和/或梳齿4。
在第一条件包括条件#6至条件#9中的一项或多项的情况下，第一终端设备确定可分配的梳齿是否满足第一条件的方式可以参考上文的描述。
可选的，在第一终端设备为第一传输分配梳齿之前，第一终端设备已为N个传输中的第三传输分配了第三梳齿，第三梳齿与第一梳齿间隔k个梳齿，k为正整数，则第一条件还包括以下一项或多项：条件#10，第一信号强度不超过第六门限值，和/或，第三信号强度不超过第十一门限值；条件#11，第一信号强度与第一干扰泄漏参数的乘积不超过第七门限值，和/或，第三信号强度与第一干扰泄漏参数的乘积不超过第十二门限值。
其中，第一干扰泄漏参数用于确定第一传输对应的终端设备泄漏到第三梳齿的信号强度。第一干扰泄漏参数与k的值相关，k的值越大，则第一干扰泄漏参数越小。第三信号强度是第三传输对应的终端设备发送的参考信号的强度。
可选的，第六门限值、第七门限值、第十一门限值或第十二门限值是协议预定义的值或者标准预定义的值。
可选的，第六门限值和第七门限值中的一个或多个与k的值和/或第三信号强度相关。例如，k的值越大，第六门限值越大。第三信号强度越大，第六门限值越大。
可选的，第十一门限值和第十二门限值中的一个或多个与k的值和/或第一信号强度相关。例如，k的值越大，第十一门限值越大。第一信号强度越大，第十一门限值越大。
如图4中的(b)所示，UE4对应的传输可以看作第三传输的一个示例，梳齿1则是第三梳齿的一个示例。
在第一条件包括条件#10的情况下，若第一信号强度不超过门限值#1，和/或，第三信号强度不超过门限值#A，则与梳齿1间隔1个梳齿的梳齿3满足第一条件。若第一信号强度不超过门限值#2，和/或，第三信号强度不超过门限值#B，则与梳齿1间隔2个梳齿的梳齿4满足第一条件，进而第一终端设备为第一传输分配的第一梳齿可以包括梳齿3和/或梳齿4。其中，门限值#1和门限值#2均是第六门限值的示例，在k等于1的情况下，第六门限值是门限值#1，在k等于2的情况下，第六门限值是门 限值#2，门限值#1与门限值#2可能不同，也可能相同。门限值#A和门限值#B均是第十一门限值的示例，在k等于1的情况下，第十一门限值是门限值#A，在k等于2的情况下，第十一门限值是门限值#B，门限值#A与门限值#B可能不同，也可能相同。
在第一条件包括条件#11的情况下，若第一信号强度与干扰泄漏参数#1的乘积不超过门限值#3，和/或，第三信号强度与干扰泄漏参数#1的乘积不超过门限值#C，则与梳齿1间隔1个梳齿的梳齿3满足第一条件。若第一信号强度与干扰泄漏参数#2的乘积不超过门限值#4，和/或，第三信号强度与干扰泄漏参数#2的乘积不超过门限值#D，则与梳齿1间隔2个梳齿的梳齿4满足第一条件。进而第一终端设备为第一传输分配的第一梳齿可以包括梳齿3和/或梳齿4。其中，门限值#3和门限值#4均是第七门限值的示例，在k等于1的情况下，第七门限值是门限值#3，在k等于2的情况下，第七门限值是门限值#4，门限值#3与门限值#4可能不同，也可能相同。门限值#C和门限值#D均是第十二门限值的示例，在k等于1的情况下，第十二门限值是门限值#C，在k等于2的情况下，第十二门限值是门限值#D，门限值#C与门限值#D可能不同，也可能相同。干扰泄漏参数#1和干扰泄漏参数#2均是第一干扰泄漏参数的示例，k等于1的情况下，第一干扰泄漏参数是干扰泄漏参数#1，k等于2的情况下，第一干扰泄漏参数是干扰泄漏参数#2，干扰泄漏参数#1大于干扰泄漏参数#2。

可以理解，第l个传输受到的干扰总和不超过第八门限值的情况下，第一终端设备为l个传输分配的每个梳齿受到的干扰总和也不超过第八门限值。假设第一终端设备为L+1个传输共分配了L’个梳齿，则L’中的第l’个梳齿受到的干扰总和可以表示为I表示L’个梳齿中与第l’个梳齿距离最远的梳齿与第l’个梳齿之间间隔的梳齿数，RSRPi表示与第l’个梳齿间隔i个梳齿的梳齿上的传输对应的终端设备发送的参考信号的强度，ci表示间隔i个梳齿的两个梳齿之间的干扰泄漏参数。
需要说明的是，若L’个梳齿中存在多个与第l’个梳齿间隔i个梳齿的梳齿，则RSRPi表示与第l’个梳齿间隔i个梳齿的多个梳齿上的传输对应的终端设备发送的参考信号的强度之和。
如图4中的(c)所示，假设第一终端设备为第一传输分配梳齿之前，已为UE2对应的传输分配了梳齿0，以及已为UE3对应的传输分配了梳齿2。
在第一条件包括条件#12的情况下，若第一终端设备为第一传输分配了梳齿1之后，梳齿0至梳齿2中每个梳齿受到的干扰总和都不超过第八门限值，则梳齿1满足第一条件。
其中，梳齿0受到的干扰总和＝RSRP0,0×c0+RSRP0,1×c1，RSRP0,0表示与梳齿0相邻的梳齿1上的第一传输对应的终端设备发送的参考信号的强度，RSRP0,1表示与梳齿0间隔一个梳齿的梳齿2上的传输对应的终端设备(即UE3)发送的参考信号的强度，c0表示相邻的两个梳齿之间的干扰泄漏参数，c1表示间隔一个梳齿的两个梳齿之间的干扰泄漏参数。

类似的，若第一终端设备为第一传输分配了梳齿3之后，梳齿0、梳齿2和梳齿3中每个梳齿受到的干扰总和都不超过第八门限值，则梳齿3满足第一条件。若第一终端设备为第一传输分配了梳齿4之后，梳齿0、梳齿2和梳齿4中每个梳齿受到的干扰总和都不超过第八门限值，则梳齿4满足第一条件。进而第一终端设备为第一传输分配的第一梳齿可以包括梳齿1、梳齿3和梳齿4中的一个或多个。
可选的，若第一信息还包括位置信息，则第一条件还包括以下一项或多项：条件#13，第一距离不低于第九门限值；条件#14，第二距离不低于第九门限值。其中，第一终端设备为N个传输中的第三传输分配的第三梳齿与第一梳齿间隔j个梳齿，第一距离是第一传输的接收端与第三传输的发送端之间的 距离，第二距离是第三传输的接收端与第一传输的发送端之间的距离，第一距离和第二距离是根据第一信息包括的位置信息确定的，j为大于或等于0的整数。位置信息包括第二终端设备的位置信息和第二终端设备的对端设备的位置信息，或者，位置信息包括以下多项：第二终端设备的位置信息、第二终端设备的对端设备的位置信息，第一终端设备的位置信息，和，第一终端设备的对端设备的位置信息。

如图4中的(c)所示，UE2对应的传输可以看作第三传输的一个示例，梳齿0则是第三梳齿的一个示例。UE3对应的传输也可以看作第三传输的一个示例，梳齿2则是第三梳齿的一个示例。假设j＝0。
在第一条件包括条件#13的情况下，对于与梳齿0相邻的梳齿1，若第一传输的接收端与UE2对应的传输的发送端之间的距离低于门限值#5，则梳齿1不满足第一条件。对于与梳齿2相邻的梳齿3，若第一传输的接收端与UE3对应的传输的发送端之间的距离不低于门限值#6，则梳齿3满足第一条件。对于与梳齿0相邻的梳齿4，若第一传输的接收端与UE2对应的传输的发送端之间的距离不低于门限值#7，则梳齿4满足第一条件。进而，第一终端设备为第一传输分配的第一梳齿包括梳齿3和/或梳齿4。其中，门限值#5至门限值#7均是第九门限值的示例，门限值#5与门限值#7中的任意两个门限值可能不同，也可能相同。

可选的，若第一终端设备为第一传输分配梳齿之前，第一终端设备已为N个传输中的第四传输分配了第四梳齿，第四传输是以第一终端设备为接收端或发送端的传输，则第一条件还包括以下一项或多项：条件#15，若N个传输占用的梳齿总数小于可分配的梳齿的数量，则第四梳齿与第一梳齿至少间隔一个梳齿，若N个传输占用的梳齿总数等于可分配的梳齿的数量，且第一梳齿与第四梳齿相邻，则第一信号强度是多个信号强度中最小的；条件#16，若N个传输占用的梳齿总数小于可分配的梳齿的数量，则第四梳齿与第一梳齿至少间隔一个梳齿，若N个传输占用的梳齿的总数等于可分配的梳齿的数量，则第一传输与第四传输的之间的距离不低于第十三门限值。
其中，多个信号强度中的每个信号强度是N个传输中未被分配梳齿的传输的信号强度，传输的信号强度指的是传输对应的终端设备发送的参考信号的强度。N个传输占用的梳齿总数指的是，N个传输对应的终端设备预约的梳齿的总数。可分配的梳齿是第一终端设备获取的传输机会包括的梳齿。第一传输与第四传输之间的距离包括：第一传输的接收端与第四传输的发送端之间的距离，和/或，第一传输的发送端与第四传输的接收端之间的距离。
条件#15也可以理解为，若可分配的梳齿未被N个传输占满，则与第四梳齿相邻的一个或多个梳齿保持空闲，即第一终端设备不会将与第四梳齿相邻的一个或多个梳齿分配给N个传输，若与第四梳齿相邻的梳齿必须分配给某个传输，则该传输是N个传输中未被分配梳齿的传输中信号强度最小的传输。
如图4中的(b)所示，UE4对应的传输可以看作第四传输的一个示例，梳齿1则是第四梳齿的一个示例。
在第一条件包括条件#15的情况下，若N个传输占用的梳齿的总数小于5，则第一终端设备不会将与梳齿1相邻的一个或多个梳齿分配给第一传输，进而第一终端设备为第一传输分配的第一梳齿与梳齿1间隔至少一个梳齿，即第一梳齿可以包括梳齿3和/或梳齿4。或者，若N个传输占用的梳齿的总 数等于4，则第一终端设备将梳齿0或梳齿2分配给N个传输中未被分配梳齿的传输中信号强度最小的传输。也就是说，若第一传输是N个传输中未被分配梳齿的传输中信号强度最小的传输，则梳齿0或梳齿2满足第一条件，进而第一梳齿可以包括梳齿0或梳齿2。或者，若N个传输占用的梳齿的总数等于5，则第一终端设备将梳齿0或梳齿2分配给N个传输中未被分配梳齿的传输中信号强度最小的传输。也就是说，若第一传输是N个传输中未被分配梳齿的传输中信号强度最小的传输，则梳齿0和梳齿2满足第一条件，进而第一梳齿可以包括梳齿0和/或梳齿2。
在第一条件包括条件#16的情况下，若N个传输占用的梳齿的总数小于5，则第一终端设备不会将与梳齿1相邻的一个或多个梳齿分配给第一传输，进而第一终端设备为第一传输分配的第一梳齿与梳齿1间隔至少一个梳齿，即第一梳齿可以包括梳齿3和/或梳齿4。或者，若N个传输占用的梳齿的总数等于4，则梳齿0或梳齿2会被分配给N个传输，若第一传输与第四传输之间的距离不低于第十三门限值，则梳齿0或梳齿2满足第一条件，进而第一梳齿可以包括梳齿0或梳齿2。或者，若N个传输占用的梳齿的总数等于5，则梳齿0和梳齿2都会被分配给N个传输，若第一传输与第四传输之间的距离不低于第十三门限值，则梳齿0和梳齿2满足第一条件，进而第一梳齿可以包括梳齿0和/或梳齿2。
基于上述技术方案，可以保证与第四梳齿相邻的梳齿空闲，或者，与第四梳齿相邻的梳齿上的传输是N个传输中未被分配梳齿的传输中信号强度最小的传输，或者，与第四梳齿相邻的梳齿上的传输与第四传输的距离较远，从而可以避免其余传输对第四传输造成太大的干扰，以及可以保证第四传输的传输性能。
可选的，若第一终端设备为第一传输分配梳齿之前，第一终端设备已为N个传输中的第五传输分配了第五梳齿，第五传输是N个传输中优先级最高的传输，或者，第五传输的优先级不低于第一传输的优先级，或者，第五传输的优先级是未被分配梳齿的传输中优先级最高的传输，则第一条件还包括以下一项或多项：条件#17，若N个传输占用的梳齿总数小于可分配的梳齿的数量，则第五梳齿与第一梳齿至少间隔一个梳齿，若N个传输占用的梳齿总数等于可分配的梳齿的数量，且第一梳齿与第五梳齿相邻，则第一信号强度是多个信号强度中最小的；条件#18，若N个传输占用的梳齿总数小于可分配的梳齿的数量，则第五梳齿与第一梳齿至少间隔一个梳齿，若N个传输占用的梳齿的总数等于可分配的梳齿的数量，则第一传输与第五传输的之间的距离不低于第十四门限值。第一传输与第五传输之间的距离包括：第一传输的接收端与第五传输的发送端之间的距离，和/或，第一传输的发送端与第五传输的接收端之间的距离。
其中，多个信号强度中的每个信号强度是N个传输中未被分配梳齿的传输的信号强度，传输的信号强度指的是传输对应的终端设备发送的参考信号的强度。
条件#17也可以理解为，若可分配的梳齿未被N个传输占满，则与第五梳齿相邻的一个或多个梳齿保持空闲，即第一终端设备不会将与第五梳齿相邻的一个或多个梳齿分配给N个传输，若与第五梳齿相邻的梳齿必须分配给某个传输，则该传输是未分配梳齿的传输中信号强度最小的传输。
如图4中的(b)所示，UE4对应的传输可以看作第五传输的一个示例，梳齿1则是第五梳齿的一个示例。
在第一条件包括条件#17的情况下，若N个传输占用的梳齿的总数小于5，则第一终端设备不会将与梳齿1相邻的一个或多个梳齿分配给第一传输，进而第一终端设备为第一传输分配的第一梳齿与梳齿1间隔至少一个梳齿，即第一梳齿可以包括梳齿3和/或梳齿4。或者，若N个传输占用的梳齿的总数等于4，则第一终端设备将梳齿0或梳齿2分配给N个传输中未被分配梳齿的传输中信号强度最小的传输。也就是说，，若第一传输是未被分配梳齿的传输中信号强度最小的传输，则梳齿0或梳齿2满足第一条件，进而第一梳齿可以包括梳齿0或梳齿2。或者，若N个传输占用的梳齿的总数等于5，则第一终端设备将梳齿0或梳齿3分配给未被分配梳齿的传输中信号强度最小的传输。也就是说，若第一传输是未被分配梳齿的传输中信号强度最小的传输，则梳齿0和梳齿2满足第一条件，进而第一梳齿可以包括梳齿0和/或梳齿2。
在第一条件包括条件#18的情况下，若N个传输占用的梳齿的总数小于5，则第一终端设备不会将与梳齿1相邻的一个或多个梳齿分配给第一传输，进而第一终端设备为第一传输分配的第一梳齿与梳齿1间隔至少一个梳齿，即第一梳齿可以包括梳齿3和/或梳齿4。或者，若N个传输占用的梳齿的总 数等于4，则梳齿0或梳齿2必然会被分配给N个传输，若第一传输与第五传输之间的距离不低于第十四门限值，则梳齿0或梳齿2满足第一条件，进而第一梳齿可以包括梳齿0或梳齿2。或者，若N个传输占用的梳齿的总数等于5，则梳齿0和梳齿3必然会被分配给N个传输，若第一传输与第五传输之间的距离不低于第十四门限值，则梳齿0和梳齿2满足第一条件，进而第一梳齿可以包括梳齿0和/或梳齿2。
基于上述技术方案，可以保证与第五梳齿相邻的梳齿空闲，或者，与第五梳齿相邻的梳齿上的传输是未被分配梳齿的传输中信号强度最小的传输，或者，与第五梳齿相邻的梳齿上的传输与第五传输之间的距离较远，从而可以避免其余传输对优先级高的传输造成太大的干扰，以及可以保证优先级高的传输的传输性能。
可选的，若第一信息还包括N个传输中每个传输的优先级，则第一条件还包括：条件#19，至少一个第二终端设备预约了与第一梳齿相邻的梳齿的情况下，第一传输的优先级高于第十门限值，和/或，第一信号强度低于第十五门限值。
可选的，第十门限值或第十五门限值是协议预定义的值或者标准预定义的值。可选的，第十门限值是固定值，或者是可变的值。例如，第十门限值和第十五门限值中的一个或多个与第四信号强度相关和/或第六传输的优先级相关。例如，第四信号强度越大，第十门限值对应的优先级越高，或者，第十五门限值越大。第六传输的优先级越高，第十门限值对应的优先级越高，或者，第十五门限值越大。第四信号强度是预约了与第一梳齿相邻的梳齿的终端设备发送的参考信号的强度，第六传输是预约了与第一梳齿相邻的梳齿的终端设备进行的传输。
如图4中的(a)所示，在第一条件包括条件#19的情况下，第一终端设备确定梳齿1是否可以分配给第一传输的过程中，第一终端设备感知到UE2预约了与梳齿1相邻的梳齿0，则第一终端设备可以根据UE2的信号强度和/或UE2对应的传输的优先级，确定第十门限值和/或第十五门限值。进而，若第一传输的优先级高于第十门限值，和/或，第一信号强度低于第十五门限值，则梳齿1满足第一条件。进而第一终端设备为第一传输分配的第一梳齿可以包括梳齿1。反之，若第一传输的优先级不高于第十门限值，和/或，第一信号强度不低于第十五门限值，则梳齿1不满足第一条件，进而第一终端设备不能为第一传输分配梳齿1。
若第一终端设备还感知到某个第二终端设备预约了与梳齿1相邻的梳齿2，则第一终端设备可以根据以下一项或多项确定第十门限值和/或第十五门限值：预约梳齿2的第二终端设备的信号强度，预约梳齿2的第二终端设备对应的传输的优先级，UE2的信号强度，UE2对应的传输的优先级。
可选的，若第一信息还包括N个传输中每个传输的优先级，则第一条件还包括：条件#20，预约了第一梳齿的第二终端设备对应的传输的优先级不超过第十六门限值。条件#20也可以理解为，若预约待分配梳齿的第二终端设备对应的传输的优先级超过第十六门限值，则该待分配梳齿不能分配给第一传输。
可选的，第十四门限值是协议预定义的值或者标准预定义的值。可选的，第十六门限值是固定值，或者是可变的值。例如，第十六门限值与第一信号强度相关和/或第一传输的优先级相关。例如，第一信号强度越大，第十六门限值对应的优先级越高。第一传输的优先级越高，第十六门限值对应的优先级越高。
如图4中的(a)所示，在第一条件包括条件#20的情况下，若UE2对应的传输的优先级不超过第十六门限值，则梳齿0满足第一条件，进而第一终端设备为第一传输分配的第一梳齿可以包括梳齿0。若UE3对应的传输的优先级超过第十六门限值，则梳齿4不满足第一条件，进而第一终端设备为第一传输分配的第一梳齿不能包括梳齿4。
需要说明的是，第一条件可以包括上述条件#1至条件#20中的一项或多项，本申请实施例对此不做限定。
还需要说明的是，若第一条件包括上述条件#1至条件#20中的多项，则第一终端设备为第一传输分配梳齿的过程中，若某个梳齿满足第一条件包括的所有条件，则第一终端设备可以将该满足第一条件包括的所有条件的梳齿分配给第一传输。
如前文所述，第一终端设备为第一传输分配梳齿的过程中，可能根据第一信息确定存在多个满足第一条件的梳齿，在此情况下，第一终端设备为第一传输分配的第一梳齿可以包括多个满足第一条件 的梳齿中的一个或多个。
或者，若多个满足第一条件的梳齿中包括第一传输对应的终端设备预约的梳齿，则第一终端设备为第一传输分配的第一梳齿可以包括第一传输对应的终端设备预约的梳齿。
或者，若多个满足第一条件的梳齿中包括与已分配的梳齿不相邻的梳齿，则第一终端设备为第一传输分配的第一梳齿可以包括与已分配的梳齿不相邻的梳齿。如图4中的(b)所示，若梳齿0、梳齿2、梳齿3和梳齿4都满足第一条件，则第一终端设备为第一传输分配的第一梳齿可以包括与梳齿1不相邻的梳齿3和/或梳齿4。
或者，第一终端设备为第一传输分配的第一梳齿包括多个满足第一条件的梳齿中干扰最低的梳齿。干扰是根据已分配资源的传输泄漏到多个满足第一条件的梳齿的信号强度确定的。若已分配资源的传输所在的梳齿与满足第一条件的梳齿相隔越近、已分配资源的传输对应的终端设备的信号强度越大，则已分配资源的传输泄漏到满足第一条件的梳齿的信号强度越大，从而对满足第一条件的梳齿的干扰越大。如4中的(c)所示，在梳齿1、梳齿3和梳齿4都满足第一条件的情况下，梳齿1和梳齿4都受到相邻的梳齿0上的干扰，且梳齿1还受到相邻的梳齿2上的干扰，因此梳齿4比梳齿1的干扰低。梳齿3与梳齿4相比，梳齿3受到相邻的梳齿2的干扰，若UE3的信号强度比UE2的信号强度大，则梳齿3受到的干扰比梳齿4受到的干扰最大。因此，梳齿4是多个满足条件的梳齿中干扰最小的梳齿，从而第一终端设备为第一传输分配的第一梳齿可以包括梳齿4。
本申请实施例对第一终端设备为N个传输分配梳齿的顺序不做限定。
一种可能的实现方式中，若N个传输包括以第一终端设备为接收端或发送端的第四传输，则第一终端设备确定优先级为第四传输分配梳齿。对于N个传输中的其余传输，第一终端设备可以按照随机的顺序为其余的传输分配梳齿，或者，按照信号强度从小到大的顺序为其余的传输分配梳齿，本申请实施例对此不做限定。
一种可能的实现方式中，若第一信息包括N个传输中每个传输的优先级，则第一终端设备确定优先为N个传输中优先级最高的第五传输分配梳齿。对于N个传输中除第五传输以外的传输，第一终端设备可以按照随机的顺序为其余的传输分配梳齿，或者，按照信号强度从小到大的顺序为其余的传输分配梳齿，或者，按照信号强度从大到小的顺序为其余的传输分配梳齿，或者，按照优先级从高到低的顺序为其余传输分配梳齿，本申请实施例对此不做限定。
可选的，第一终端设备按照信号强度的排序(例如，从大到小的顺序，或从小到大的顺序)为其余传输分配梳齿的情况下，若存在多个传输的信号强度相等，则第一终端设备按照随机的顺序为该多个传输分配梳齿，或者，按照优先级从高到低的顺序为该多个传输分配梳齿，本申请实施例对此不做限定。
可选的，第一终端设备按照优先级从高到低的顺序为其余传输分配梳齿的情况下，若存在多个传输的优先级相同，则第一终端设备按照随机的顺序为该多个传输分配梳齿，或者，按照信号强度从大到小的顺序为该多个传输分配梳齿，或者，按照信号强度从小到大的顺序为该多个传输分配梳齿，本申请实施例对此不做限定。
一种可能的实现方式中，若第一信息包括位置信息，则第一终端设备确定优先为距离最近的两个传输分配梳齿。其中，距离指的是一个传输的接收端与另一个传输的发送端之间的距离，或者，距离指的是一个传输的发送端与另一个传输的接收端之间的距离。也就是说，在对N个传输分配梳齿之前，第一终端设备首先根据第一信息包括位置信息，确定N个传输中每个传输的接收端与其余传输的发送端之间的距离，从而得到共N(N-1)个距离值，进而第一终端设备确定优先级为N(N-1)个距离值中的最小距离值对应的两个传输分配梳齿。例如，N(N-1)个距离值中的最小距离值是第一传输的发送端与第二传输的接收端之间的距离，则第一终端设备优先为第一传输和第二传输分配梳齿。
可选的，第一终端设备为距离最近的两个传输分配的梳齿不相邻。
一种可能的实现方式中，若第一信息包括N个传输中每个传输对应的终端设备预约的梳齿的数量，则第一终端设备根据第一信息，按照预约的梳齿的数量从大到小的顺序为N个传输分配梳齿。
可选的，若存在多个传输对应的终端设备预约的梳齿的数量相等，则第一终端设备按照随机的顺序为该多个传输分配梳齿，或者，按照优先级从高到低的顺序为该多个传输分配梳齿，或者，按照信号强度从大到小的顺序为该多个传输分配梳齿，或者，按照信号强度从小到大的顺序为该多个传输分 配梳齿，本申请实施例对此不做限定。
一种可能的实现方式中，若第一信息包括N个传输中每个传输的吞吐量，则第一终端设备根据第一信息，按照吞吐量从大到小的顺序为N个传输分配梳齿。
可选的，若存在多个传输的吞吐量相等，则第一终端设备按照随机的顺序为该多个传输分配梳齿，或者，按照优先级从高到低的顺序为该多个传输分配梳齿，或者，按照信号强度从大到小的顺序为该多个传输分配梳齿，本申请实施例对此不做限定。
需要说明的是，第一终端设备按照上述任意一种顺序为N个传输分配梳齿的情况下，第一终端设备为N个传输中的每个传输分配梳齿都满足第一条件。例如，第一终端设备按照优先级从高到低的顺序为N个传输分配梳齿的情况下，对于N个传输中的第一传输，若某个梳齿满足第一条件，则第一终端设备可以将该满足第一条件的梳齿分配给第一传输。
可选的，在S340之前，方法300还包括：第一终端设备从M个传输中确定N个传输。M为大于或等于N的整数。
其中，M个传输是第一终端设备根据接收到的一个或多个预约消息确定的传输。M个传输的时间段存在重叠，且M个传输中每个传输的时间段都在第一终端设备获取的传输机会内。传输的时间段指的是传输对应的终端设备发送传输的时间段。
示例性的，第一信息包括M个传输中每个传输的优先级，第一终端设备按照传输的优先级从高到低的顺序，从M个传输中确定N个传输。
又示例性的，第一信息包括个传输中每个传输的优先级，第一终端设备确定N个传输包括M个传输中以第一终端设备为接收端或发送端的N’个传输，和/或，M-N’个传输中按照传输的优先级从高到低的顺序确定的N-N’个传输。N’为正整数。
可选的，若以第一终端设备为接收端或发送端的N’个传输占用的梳齿的总数大于可分配的梳齿的数量，则第一终端设备按照传输的优先级从高到低的顺序，从N’个传输中确定N个传输。
可选的，若M个传输占用的梳齿的总数大于可分配的梳齿的数量，则在S340之前，第一终端设备从M个传输中确定N个传输。
S350，第一终端设备向第二终端设备发送资源分配信息。
相应的，在S350中，第二终端设备接收来自第一终端设备的资源分配信息。
资源分配信息用于指示第一终端设备为第二终端设备分配的梳齿。例如，资源分配信息可以包括第一终端设备为第二终端设备分配的梳齿的索引。
可选的，若N个传输中包括以第一终端设备为接收端的至少一个传输，则方法300还包括：第一终端设备接收该至少一个传输。
可选的，若N个传输中包括以第一终端设备为发送端的至少一个传输，则方法300还包括：第一终端设备发送该至少一个传输。
在本申请实施例中，第一终端设备获取到传输机会之后，第一终端设备可以将传输机会包括的至少一个梳齿分配给N个传输，使得N个传输对应的终端设备可以使用该至少一个梳齿进行传输，从而可以提高资源利用率。
此外，在本申请实施例中，第一终端设备可以根据以下一项或多项为N个传输分配至少一个梳齿：第二终端设备发送的参考信号的强度，第一终端设备发送的参考信号强度，N个传输中每个传输的优先级，第二终端设备的位置信息，第二终端设备的对端设备的位置信息，第一终端设备的位置信息，第一终端设备的对端设备的位置信息，从而可以避免为N个传输分配的至少一个梳齿的梳齿间干扰(或者称为带间泄漏(inter-block emission，IBE))过大。例如，第一终端设备根据参考信号的强度为N个传输分配至少一个梳齿时，若N个传输中的两个传输分别对应的终端设备发送参考信号的强度过大，则第一终端设备为该两个传输分配的梳齿不相邻，从而可以避免两个传输之间互相干扰。
下面结合图5至图9所示的示例，说明本申请实施例提供的资源分配的方法。在图5至图9所示的示例中，SCS为30 KHz，UE1(第一终端设备的示例)获取到的传输机会包括的可分配的梳齿的数量为5个，即图5至图9中所示的梳齿0至梳齿4。图5至图9中的UE1是第一终端设备的示例，其他UE(例如UE2)是第二终端设备的示例。
示例1：UE1优先为N个传输中优先级最高的传输分配梳齿，且第一条件包括条件#16。
如图5所示，UE1接收到来自UE2至UE5的预约消息之后，依次测量UE2至UE5发送的参考信号，并得到UE2至UE5发送的参考信号的强度，UE2至UE5发送的参考信号的强度分别记为RSRP2、RSRP3、RSRP4和RSRP5。假设RSRP2至RSRP5从大到小的排序为：RSRP5＞RSRP4＞RSRP3＞RSRP2。进而，UE1 LBT成功之后，则为UE2至UE5对应的传输分配梳齿。
如果UE2至UE4分别对应的传输中，UE2对应的传输的优先级最高，则UE1优先为UE2分配梳齿。例如，UE2预约了梳齿0，则UE1可以为UE2分配梳齿0。进而，在UE1至UE4对应的传输占用的梳齿的总数是4的情况下，根据条件#16，UE1确定与梳齿0相邻的梳齿1和梳齿4中的一个梳齿保持空闲，而另一个梳齿分配给UE3至UE5中信号强度最小的UE(即UE3)。例如，UE1确定梳齿1保持空闲，梳齿4分配给UE3。进而，为了避免UE3受到的干扰过大，UE1可以将梳齿3分配给信号强度更小的UE4，最后将梳齿2分配给UE5。或者，UE1为UE4和UE5分配梳齿的过程中，若UE5对应的传输的优先级更高，则UE1可以确定为UE5分配干扰更小的梳齿，即UE1将梳齿2分配给UE5，最后将梳齿3分配给UE4。
UE1为UE2至UE5分配了梳齿之后，可以发送COT分享指示，从而向UE2至UE5指示UE1为UE2至UE5分别分配的梳齿。
示例2：UE1优先为N个传输中以UE1为接收端的传输分配梳齿，且第一条件包括条件#15。
如图6所示，UE1接收到来自UE2至UE7的预约消息之后，依次测量UE2至UE7发送的参考信号，并得到UE2至UE7发送的参考信号的强度，UE2至UE7发送的参考信号的强度分别记为RSRP2、RSRP3、RSRP4、RSRP5、RSRP6和RSRP7。假设RSRP2至RSRP7从大到小的排序为：RSRP7＞RSRP5＞RSRP4＞RSRP3＞RSRP2＞RSRP6。进而，UE1 LBT成功之后，从UE2至UE7分别对应的传输中，选择以UE1为接收端的传输，以UE1为接收端的传输包括UE2对应的传输和UE3对应的传输，然后UE1再按照传输的优先级从高到低的顺序从UE4至UE7对应的传输中选择UE4至UE6的传输，进而UE1为UE2至UE6对应的传输分配梳齿。
在以UE1为接收端的传输包括两个传输的情况下，UE1可以优先为优先级最高的传输分配梳齿。例如，U2对应的传输的优先级最高，则UE1优先为UE2分配梳齿。例如，UE2预约了梳齿0，则UE1可以为UE2分配梳齿0。进而，根据条件#15，UE1确定与梳齿0相邻的梳齿1和梳齿4分配给UE3至UE6中信号强度最小的两个UE。例如，UE1将梳齿1分配给UE6，将梳齿4分配给UE3。进而，如果UE3对应的传输的优先级比UE6对应的传输的优先级高，则为了避免UE3受到的干扰过大，UE1可以将梳齿3分配给信号强度更小的UE4，最后将梳齿2分配给UE5。或者，UE1为UE4和UE5分配梳齿的过程中，若UE5对应的传输的优先级更高，则UE1可以确定为UE5分配干扰更小的梳齿，即UE1将梳齿2分配给UE5，最后将梳齿3分配给UE4。
UE1为UE2至UE6分配了梳齿之后，可以发送COT分享指示，从而向UE2至UE6指示UE1为UE2至UE6分别分配的梳齿。
示例3：UE1按照优先级从高到低的顺序分配梳齿，且第一条件包括条件#1和条件#3。
如图7所示，UE1接收到来自UE2至UE6的预约消息，假设UE1至UE6分别对应的传输按照优先级从高到低的排序为：UE1对应的传输，UE2对应的传输，UE3对应的传输，UE4对应的传输，UE5对应的传输，UE6对应的传输。进而，UE1 LBT成功之后，按照传输的优先级从高到低的顺序为UE1至UE6分配梳齿。
由于UE1对应的传输的优先级最高，因此UE1首先为UE1分配梳齿，例如，UE1为UE1随机分配梳齿2。
进而，UE1为UE2对应的传输分配梳齿，假设梳齿1和梳齿3不满足第一条件，例如max(UE1的信号强度，UE2的信号强度)-min(UE1的信号强度，UE2的信号强度)＞第二门限值，那么UE2只能占用梳齿0或梳齿4。例如，UE1随机为UE2分配梳齿0。又例如，UE1将梳齿0和梳齿4中干扰最小的梳齿分配给UE2。由于，梳齿0和梳齿4的干扰相同，则UE1可以随机为UE2分配梳齿0。
进而，UE1为UE3对应的传输分配梳齿，假设梳齿1和梳齿3不满足第一条件，例如，UE3的信号强度高于第一门限值，那么UE1只能为UE3分配梳齿4。假设梳齿1和梳齿3满足第一条件，则UE1可以将梳齿1、梳齿3和梳齿4中的一个分配给UE3，例如，UE1将梳齿1、梳齿3和梳齿4中干扰最小的梳齿分配给UE3。若UE1的信号强度大于UE2的信号强度，则梳齿1、梳齿3和梳齿4中干 扰最小的是梳齿4，从而UE1将梳齿4分配给UE3。
进而，UE1为UE4对应的传输分配梳齿，假设梳齿1和梳齿3都满足第一条件，那么UE3可以占用梳齿1或梳齿3。例如UE1为UE4随机分配梳齿1。又例如，UE1将梳齿1和梳齿3中干扰最小的梳齿分配给UE4。若UE3的信号强度大于UE2的信号强度，则梳齿1和梳齿3中干扰最小的是梳齿1，从而UE1将梳齿1分配给UE4。
进而，UE1为UE5对应的传输分配梳齿，假设梳齿1不满足第一条件，那么UE1不为UE5分配梳齿。
进而，UE1为UE6对应的传输分配梳齿，假设梳齿1满足第一条件，那么UE1将梳齿1分配给UE6。
可选的，UE1为每个传输分配梳齿的过程中，若存在多个满足第一条件的梳齿，则UE1为每个传输选择干扰最小的梳齿。
例如，UE1为UE1对应的传输分配梳齿的过程中，由于每个梳齿都满足第一条件，且每个梳齿的干扰相同，则UE1随机为UE1分配梳齿，例如UE1随机为UE1分配梳齿2。进而UE1为UE2对应的传输分配梳齿，假设梳齿0和梳齿4满足第一条件，则UE1将梳齿0和梳齿4中干扰最小的梳齿分配给UE2。进而，由于梳齿0和梳齿4的干扰相同，则UE1可以随机为UE2分配梳齿0。进而UE1为UE3对应的传输分配梳齿，若梳齿1、梳齿3和梳齿4都满足第一条件，则进而UE1为UE4对应的传输分配梳齿，假设梳齿1和梳齿3都满足第一条件，则UE1将梳齿1和梳齿3中干扰最小的梳齿分配给UE4。若UE3的信号强度大于UE2的信号强度，则梳齿1和梳齿3中干扰最小的是梳齿1，从而UE1将梳齿1分配给UE4。最后，UE1将剩余的梳齿1分配给UE6。
示例4：UE1优先为以UE1为接收端的传输分配梳齿，且第一条件包括条件#15。
如图8中的(a)所示，假设N个传输包括UE1对应的传输，UE2对应的传输和UE3对应的传输。UE1优先为UE1对应的传输分配梳齿，例如，UE1随机将梳齿2分配给UE1。进而根据条件#15，UE1将与梳齿2不相邻的梳齿0和梳齿4分别分配给UE2和UE3。
如图8中的(b)所示，若N个传输还包括UE4对应的传输和UE5对应的传输，则UE1为UE1分配梳齿2之后，根据条件#15，将梳齿2相邻的梳齿1和梳齿3分别分配给UE2至UE5中信号强度最小的两个UE。例如，UE2至UE5中信号最小的两个UE是UE4和UE5，则UE1将梳齿1分配给UE4，将梳齿3分配给UE5。进而，UE1可以根据UE4对应的传输的优先级和UE5对应的传输的优先级，为UE2和UE3分配梳齿。例如，若UE5对应的传输的优先级比UE4对应的传输的优先级高，则在UE2的信号强度比UE3的信号强度大的情况下，UE1将梳齿3相邻的梳齿4分配给UE3，将梳齿0分配给UE2，从而保证UE5受到的干扰比UE4受到的干扰更小。
或者，在图8中的(b)所示的示例中，UE1优先为UE1分配梳齿2之后，按照优先级从高到低的顺序为其余传输分配梳齿。假设UE2至UE5对应的传输按照优先级从高到低的排序为：UE5对应的传输，UE4对应的传输，UE3对应的传输，UE2对应的传输。进而，UE1为UE5分配梳齿的过程中，若除梳齿2以外的其余4个梳齿都满足第一条件，则UE1可以随机为UE5分配梳齿3。进而，UE1为UE4分配梳齿的过程中，若梳齿2和梳齿3以外的其余3个梳齿都满足第一条件，则UE1可以随机为UE4分配梳齿1。进而，UE1为UE3分配梳齿的过程中，若梳齿0和梳齿4都满足第一条件，则UE1可以随机为UE3分配梳齿4。最后，UE1为UE2分配梳齿的过程中，若梳齿0满足第一条件，则UE1为UE2分配梳齿0。
可选的，UE1为UE1分配梳齿的过程中，第一条件还包括条件#6和条件#7。如图8中的(c)所示，UE1对应的传输的优先级为优先级1，UE4对应的传输的优先级为优先级4，UE4的信号强度为RSRP4，UE4预约了梳齿0；UE2对应的传输的优先级为优先级2，UE2的信号强度为RSRP2，UE2预约了梳齿1；UE3对应的传输的优先级为优先级3，UE3的信号强度为RSRP3，UE3预约了梳齿3。进而，UE1为UE1分配梳齿的过程中，基于条件#6，由于梳齿2和梳齿4未被其他UE预约，因此对于UE1，梳齿2和梳齿4是可用的梳齿。基于条件#7，由于RSRP4＞RSRP_th(优先级4，优先级1)，则梳齿0不满足条件#7，以及RSRP2＞RSRP_th(优先级2，优先级1)，则梳齿1不满足条件#7，因此对于UE1，梳齿0和梳齿1是不可用的梳齿。基于条件#7，由于RSRP3＜RSRP_th(优先级3，优先级1)，则梳齿3满足条件#7，因此对于UE1，梳齿3是可用的梳齿。进而，UE1可以为UE1分配梳 齿2、梳齿3或梳齿4。
其中，RSRP_th(优先级4，优先级1)是第四门限值的一个示例，RSRP_th(优先级4，优先级1)表示根据UE1对应的传输的优先级和UE4对应的传输的优先级确定的第四门限值。RSRP_th(优先级2，优先级1)是第四门限值的一个示例，RSRP_th(优先级2，优先级1)表示根据UE1对应的传输的优先级和UE2对应的传输的优先级确定的第四门限值。RSRP_th(优先级4，优先级1)是第四门限值的一个示例，RSRP_th(优先级3，优先级1)表示根据UE1对应的传输的优先级和UE3对应的传输的优先级确定的第四门限值。
可选的，UE1为UE1分配梳齿的过程中，第一条件包括条件#7和条件#9。如图8中的(d)所示，UE1确定梳齿2是否可以分配给UE1的过程中，基于条件#9和条件#7，若UE2的信号强度不超过第五门限值，UE3的信号强度不超过第五门限值，且UE5的信号强度低于第四门限值，则梳齿2满足第一条件。进而UE1可以将梳齿2分配给UE1。
可选的，UE1为UE1分配梳齿的过程中，第一条件包括条件#19。如图8中的(d)所示，UE1确定梳齿2是否可以分配给UE1的过程中，基于条件#19，UE1可以根据以下一项或多项确定第十门限值和/或第十五门限值：UE2的信号强度，UE2对应的传输的优先级，UE3的信号强度，UE3对应的传输的优先级，进而若UE1对应的传输的优先级高于第十门限值，和/或，UE1的信号强度低于第十五门限值，则梳齿2满足第一条件。进而UE1可以将梳齿2分配给UE1。
示例5：UE1优先为距离最近的两个传输分配梳齿，且为距离最近的两个传输分配的梳齿不相邻。
如图9所示，假设N个传输包括UE1至UE5分别对应的传输，UE1优先为距离最近的两个传输分配梳齿。如图9中的(a)所示，由于UE1对应的传输的接收端(UE1’)与UE2的距离最近，则UE1优先为UE1对应的传输和UE2对应的传输分配梳齿，且UE1为UE1和UE2分配的梳齿不相邻。如图9中的(b)所示，UE1可以为UE1分配梳齿2，以及为UE2分配梳齿0。进而，如图9中的(a)所示，在剩余的三个传输中，UE4对应的传输的接收端与UE5的距离最近，则UE1为UE4和UE5分配梳齿，且UE1为UE4和UE5分配的梳齿不相邻。如图9中的(b)所示，UE1可以为UE4分配梳齿1，以及为UE5分配梳齿3。最后，UE1将剩余的梳齿4分配给UE3。

条件#17也可以理解为，若可分配的梳齿未被N个传输占满，则与第五梳齿相邻的一个或多个梳齿保持空闲，即第一终端设备不会将与第五梳齿相邻的一个或多个梳齿分配给N个传输，若与第五梳齿相邻的梳齿必须分配给某个传输，则该传输是未被分配梳齿的传输中信号强度最小的传输。

还需要说明的是，若第一条件包括上述条件#1至条件#14、条件#17至条件#20中的多项，则第一终端设备为第一传输分配梳齿的过程中，若某个梳齿满足第一条件包括的所有条件，则第一终端设备可以将该满足第一条件包括的所有条件的梳齿分配给第一传输。
下面结合图11，以第一条件包括条件#6和条件#7为例，说明第一终端设备如何为N个传输中的第一传输分配梳齿。
如图11所示，在SCS为30 KHz的情况下，第一终端设备获取的传输机会包括的可分配的梳齿数量为5个，即图11所示的梳齿0至梳齿4。如图11所示，假设UE1(第一终端设备的一例)对应的传输#a(传输#a属于N个传输)的优先级为优先级1，UE4(第二终端设备的一例)对应的传输的优先级为优先级4，UE4的信号强度为RSRP4，UE4预约了梳齿0；UE2(第二终端设备的一例)对应的传输的优先级为优先级2，UE2的信号强度为RSRP2，UE2预约了梳齿1；UE3(第二终端设备的一例)对应的传输的优先级为优先级3，UE3的信号强度为RSRP3，UE3预约了梳齿3。
进而，UE1为传输#a分配梳齿的过程中，基于条件#6，由于梳齿2和梳齿4未被其他UE预约，因此对于传输#a，梳齿2和梳齿4是可用的梳齿。基于条件#7，由于RSRP4＞RSRP_th(优先级4，优先级1)，则梳齿0不满足条件#7，以及RSRP2＞RSRP_th(优先级2，优先级1)，则梳齿1不满足条件#7，因此对于UE1，梳齿0和梳齿1是不可用的梳齿。基于条件#7，由于RSRP3＜RSRP_th(优先级3，优先级1)，则梳齿3满足条件#7，因此对于传输#a，梳齿3是可用的梳齿。进而，UE1可以为UE1分配梳齿2、梳齿3或梳齿4。
其中，RSRP_th(优先级4，优先级1)是第四门限值的一个示例，RSRP_th(优先级4，优先级1)表示根据UE1对应的传输的优先级和UE4对应的传输的优先级确定的第四门限值。RSRP_th(优先级2，优先级1)是第四门限值的一个示例，RSRP_th(优先级2，优先级1)表示根据UE1对应的传输的优先级和UE2对应的传输的优先级确定的第四门限值。RSRP_th(优先级4，优先级1)是第四门限值的一个示例，RSRP_th(优先级3，优先级1)表示根据UE1对应的传输的优先级和UE3对应的传输的优先级确定的第四门限值。
下面结合图12，以第一条件包括条件#7和条件#9为例，或者以第一条件包括条件#19为例，说明第一终端设备如何为N个传输中的第一传输分配梳齿。
如图12所示，在SCS为30 KHz的情况下，第一终端设备获取的传输机会包括的可分配的梳齿数量为5个，即图12所示的梳齿0至梳齿4。如图12所示，UE1为第一终端设备的一例，UE2(第二终端设备的一例)预约了梳齿1；UE3(第二终端设备的一例)预约了梳齿3；UE5(第二终端设备的一例)预约了梳齿2。
在第一条件包括条件#7和条件#9的情况下，UE1确定梳齿2是否可以分配给UE1对应的传输#a的过程中，基于条件#9和条件#7，若UE2的信号强度不超过第五门限值，UE3的信号强度不超过第五门限值，且UE5的信号强度低于第四门限值，则梳齿2满足第一条件。进而UE1可以将梳齿2分配给 传输#a。
在第一条件包括条件#19的情况下，UE1确定梳齿2是否可以分配给传输#a的过程中，基于条件#19，UE1可以根据以下一项或多项确定第十门限值和/或第十五门限值：UE2的信号强度，UE2对应的传输的优先级，UE3的信号强度，UE3对应的传输的优先级，进而若传输#a的优先级高于第十门限值，和/或，传输#a的接收端测量UE1发送的参考信号得到的信号强度低于第十五门限值，则梳齿2满足第一条件。进而UE1可以将梳齿2分配给传输#a。

S1050，第一终端设备发送N个传输。
第一终端设备在为N个传输分配的至少一个梳齿上发送N个传输。
在本申请实施例中，第一终端设备获取到传输机会之后，第一终端设备可以将传输机会包括的至少一个梳齿分配给N个传输，并且在至少一个梳齿上发送该N个传输，从而可以提高资源利用率。
此外，在本申请实施例中，第一终端设备可以根据以下一项或多项为N个传输分配至少一个梳齿：第二终端设备发送的参考信号的强度，第一终端设备发送的参考信号强度，N个传输中每个传输的优先级，第一终端设备的位置信息，第一终端设备的对端设备的位置信息，从而可以避免为N个传输分配的至少一个梳齿的梳齿间干扰(或者称为带间泄漏(inter-block emission，IBE))过大。例如，第一终端设备根据参考信号的强度为N个传输分配至少一个梳齿时，若N个传输中的两个传输分别对应的接收端测量第一终端设备发送的参考信号得到的信号强度过大，则第一终端设备为该两个传输分配的梳齿不相邻，从而可以避免两个传输之间互相干扰。
