具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：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)、通用移动通信系统(universal mobile telecommunication system，UMTS)、未来的第五代(5th generation，5G)系统或新无线(new radio，NR)等。
图1示出了本申请实施例可应用的一种网络架构的示意图。如图1所示，本申请实施例的通信系统100可以包括接入设备101和多个终端设备，例如终端设备102、终端设备103和终端设备104等，终端设备之间可以使用接入设备配置的资源池进行侧行链路通信。
即，终端设备之间可以建立侧行链路(sidelink，SL)，并通过侧行链路进行业务传传输。
作为示例而非限定，该业务可以包括但不限于车联网(Vehicle to everything，V2X)通信业务，或设备间通信业务等。
本申请提供的方案适用于基于SL通信的通信设备，以上列举的终端设备仅为该通信设备的一例，本申请并未限定于此，其他能够使用SL通信的设备均落入本申请的保护范围内，例如，本申请的通信设备还可以包括网络设备。以下为了便于理解和说明，以终端设备作为本申请提供的方案的执行主体(即，通信设备)为例，进行说明。
本申请实施例中的终端设备也可以称为：用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)、接入终端、用户单元、用户站、移动站、移动台、远方站、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等。
终端设备可以是一种向用户提供语音/数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、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、个人数字助理(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用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
作为示例而非限定，在本申请实施例中，该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。
此外，在本申请实施例中，终端设备还可以是物联网(internet of things，IoT)系统中的终端设备，IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。需要说明的，图1示出的无线通信系统100仅仅是为了更加清楚的说明本申请的技术方案，并不构成对本申请的限定，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，本申请提供的技术方案对于类似的技术问题，同样适用。
在本申请实施例中，IOT技术可以通过例如窄带(narrow band)NB技术，做到海量连接，深度覆盖，终端省电。例如，NB可以包括一个资源块(resource bloc，RB)，即，NB的带宽只有180KB。要做到海量接入，必须要求终端在接入上是离散的，根据本申请实施例的通信方法，能够有效解决IOT技术海量终端在通过NB接入网络时的拥塞问题。
该通信系统100可以是PLMN网络、D2D网络、M2M网络或者其他网络。
另外，本申请实施例中的接入设备可以是用于与终端设备通信的设备，该接入设备也可以称为接入网设备或无线接入网设备，例如，接入设备可以是LTE系统中的演进型基站(evolved NodeB，eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，或者该接入设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的接入设备或者未来演进的PLMN网络中的接入设备等，可以是WLAN中的接入点(access point，AP)，可以是新型无线系统(new radio，NR)系统中的gNB本申请实施例并不限定。
另外，在本申请实施例中，接入设备是RAN中的设备，或者说，是将终端设备接入到无线网络的RAN节点。例如，作为示例而非限定，作为接入设备，可以列举：gNB、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)等。在一种网络结构中，网络设备可以包括集中单元(centralized unit，CU)节点、或分布单元(distributed unit，DU)节点、或包括CU节点和DU节点的RAN设备、或者控制面CU节点(CU-CP节点)和用户面CU节点(CU-UP节点)以及DU节点的RAN设备。
本申请的通信系统还可以适用于车联网(vehicle to everything，V2X)技术，即，本申请的终端设备还可以是汽车，例如，智能汽车或自动驾驶汽车。
V2X中的“X”代表不同的通信目标，V2X可以包括但不限于：汽车对汽车(vehicle to vehicl，V2V)，汽车对路标设(vehicle to infrastructure，V2I)，汽车对网络(vehicle to network，V2N)，和汽车对行人(vehicle to pedestrian，V2P)。
在V2X中，接入设备可以为UE配置“区域(zone)”。其中，该区域也可以称为地理区域。当区域配置了以后，世界将被分成多个区域，这些区域由参考点、长、宽来进行定义。UE在进行区域标识(identifier，ID)确定的时候，会使用区域的长、宽、长度上面的区域数量、宽度上面的区域数量以及参考点进行其余的操作。上述信息可以由接入设备进行配置。
V2X的业务可以通过两种方式提供：即，基于PC5接口的方式和基于Uu接口的方式。其中PC5接口是在侧行链路(sidelink)基础上定义的接口，使用这种接口，通信设备(例如，汽车)之间可以直接进行通信传输。PC5接口可以在覆盖外(out of coverage，OOC)和覆盖内(in coverage，IC)下使用，但只有得到授权的通信设备才能使用PC5接口进行传输。
在本申请实施例中，V2X侧行链路的资源分配支持两种模式，即，基站分配资源模式(可以称为：mode 1)和UE自主资源选择模式(可以称为：mode2)。
基站分配资源模式要求UE处于无线资源控制(radio resource control，RRC)连接态。在资源分配过程中，UE首先向接入设备(例如，eNB)进行资源请求，然后接入设备会统一根据各UE的缓存状态报告BSR分配V2X侧行链路上的控制和数据资源。作为示例而非限定，在本申请中，基站分配资源模式下的分配可以包括动态模式和预配置模式，基站分配的资源包括初始资源和/或重传资源。
本申请实施例提供的方案主要涉及终端自主选择资源的模式(例如mode 2或mode 4)，终端基于自身侦听的结果在选择窗内的侧行资源池(sidelink resource pool)选择用于发送侧行信息的资源，侧行资源池可以是终端通过网络设备的资源池配置信息获得的，可以是协议预定义的，也可以是通过终端自身保存的预配置信息获得的，其中侧行资源池可以理解为可用于侧行通信的时频资源的集合。
例如，一个侧行资源池在频域上可以包括多个频率单元且若干个频率单元可组成一个子信道(subchannel)，具体一个资源池包括的频率单元的总数和一个子信道包括的频率单元的总数取决于高层(例如，网络设备)配置或者预定义。频域单元的单位可以是物理资源块(physical resource block，PRB)、资源块(resource block，RB)、资源单元(resource element，RE)或控制信道元素(control channel element，CCE)等。
假设终端在时隙n触发资源选择，终端持续侦听侦听窗口内所有属于SL资源池的时隙中除过终端自身进行过传输的时隙之外剩余的所有时隙，根据侦听的结果从选择窗口内排除已经被其他终端预留的资源，然后终端将排除后得到的候选资源集合上报给终端高层(higher layers)。上述“侦听”也可以称为监听、监测或检测。
应理解，本申请中描述的“预定义”是指某个值或某个参数定义于通信协议中，一般的通信协议中定义的内容保存于基带芯片中。本申请中描述“预配置”是指某个值或某个参数在通信协议中允许被配置为不同的取值，具体可以根据各国家或行业标准确定，所以该值或该参数在每个国家/地区/行业可以有不同的预配置的取值，预配置的取值在设备出厂时已经预配置于设备或装置中，例如终端整机、通信模块或基带芯片等。
应理解，本申请中的表达式[A,B]表示包含边界点A和B的取值范围，表达式(A,B)表示同时不包含边界点A和B的取值范围。同理地，表达式[A,B)表示包含边界点A且不包含边界点B的取值范围，表达式(A,B]表示不包含边界点A且包含边界点B的取值范围。 全文其他地方对此不再赘述。
下面以图1的UE 102作为自主资源选择的主体为例进行描述。
假设UE 102在某个时隙触发资源选择，该UE 102可持续侦听资源侦听窗口内所有属于侧行链路资源池的时隙中除过该UE自身进行过传输的时隙之外，剩余的所有时隙，再根据侦听的结果，从资源选择窗口中排除已经被其他UE(例如UE103、104)使用或预留的资源，其中，所述资源选择窗口为资源选择触发之后的多个时隙。自主资源选择的具体流程如下：
1)定义选择窗口(selection window)为时隙范围[n+T 1,n+T 2]，n+T 1为起始时隙编号，n+T 2为结尾时隙编号，其中终端在时隙n触发资源选择。假设SL资源池中每个时隙上的频域资源包括的子信道个数为N subCH，SL资源池中每个时隙上包含的子信道构成的子信道集合可以表示为
Figure PCTCN2020142526-appb-000001
一个候选资源R x,y被定义为在时域上位于选择窗口[n+T 1，n+T 2]内属于SL资源池的时隙
Figure PCTCN2020142526-appb-000002
在频域上位于子信道索引为{x+j}的子信道集合，其中j＝0,...,L subCH-1。也就是说，一个候选资源在频域上体现为长度等于L subCH的一组连续的子信道，在时域上位于一个时隙。其中L subCH可以为用于承载终端的待发送数据的PSSCH和/或PSCCH包括的子信道的个数。根据上述候选资源的定义，选择窗中的每个时隙上的候选资源的个数为N subCH-L subCH+1。进一步地，选择窗中的SL资源池内任何一组符合上述条件的，即一个时隙上长度等于L subCH的连续子信道，都被认为是一个候选资源R x,y，选择窗内全部候选资源的总数记为M total。
下面以一个具体的示例简单说明一个时隙上的候选资源，如图2所示，频域资源池包括的最大子信道个数N subCH为8，可以理解为SL资源池中一个时隙范围包含的用于SL的最大子信道个数为8，那么频域资源池对应的子信道集合可以表示为S＝{S 0,S 1,…,S 7}，如图中示出的某个时隙上编号0～7的8个连续的子信道。假设候选资源的频域长度L subCH为2，例如用于承载待发送数据的PSSCH需占用的子信道的个数为2，则每个时隙上的候选资源总数为N subCH-L subCH+1＝7。图2中标出了该时隙上由子信道0～7构成的所有7个候选资源，可以理解的，基于相同的原则可以得到选择窗内全部候选资源。
2)侦听窗口可定义为时隙范围

其中T 0由高层参数sl_SensingWindow配置，
Figure PCTCN2020142526-appb-000004
由终端根据下方的表1确定。表中的μ SL与终端的SL带宽部分(bandwidth part，BWP)对应的子载波间隔(sub-carrier spacing，SCS)有关，μ SL可以理解为SL BWP的SCS配置参数。具体的，子载波间隔SCS与μ SL的对应关系由下方的表2示出。终端可以根据表1和表2确定参数
Figure PCTCN2020142526-appb-000005
其中表1和表2为协议预定义的。终端需要监听(monitor)侦听窗口内除其自身进行发送的且属于SL资源池的时隙，其中对时隙的监听基于在这些时隙上的PSCCH解码和RSRP测量，PSCCH上承载其他终端发送的侧行控制信息(sidelink control information，SCI)。触发时隙n和侦听窗口以及选择窗口之间时域上的关系可以如图3所示。

3)定义门限Th(prio RX,prio TX)为接收到的SCI指示的优先级值和终端的待发送数据对应的优先级值的函数，其中SCI指示的优先级值可以是PSSCH和/或PSCCH对应的优先级值。参数prio RX表示接收到的其他终端的SCI中指示的优先级值，参数prio TX表示终端自身的待发送数据对应的优先级值。应理解，一般在协议定义当中优先级值越高表示优先级越低。
4)定义包括全部M total个候选资源的集合为S A。
5)如果一个候选资源R x,y同时满足以下条件，则终端应当将该满足条件的候选资源R x,y从集合S A中排除：
a)终端没有侦听时隙

7)如果候选资源集合S A中剩余的候选资源少于M total的X％，则将RSRP门限Th prioTX,prioRX升高3dB,然后重复步骤4)至6)。X的值可以从配置的多个值中选取，例如从20,35,50中选择。
上述mode2模式中，侦听UE是待发送数据的UE(称为发送UE或发送终端)，例如上述UE 102。由于发送UE 102仅根据自身资源侦听的结果在资源选择窗口内自行选择传输资源进行通信，并未考虑接收UE侧(例如UE 103)的干扰水平，可能会产生隐藏终端和暴露终端，进而导致干扰增强或资源浪费的问题。
具体而言，如图4所示，假设UE A和UE B为一个传输对，UE A为发送UE，UE B为接收UE；UE C和UE D为一个传输对，UE C为发送UE，UE D为接收UE。当UE-A和UE-C同时在相同的资源上进行传输时，会造成相互干扰，UE-A会干扰UE-D的接收，UE-C会干扰UE-B的接收。按照上述技术中发端侦听的原则，UE-A在进行资源排除的步骤6)时，发送UE对侦听链路进行RSRP测量，即UE-C到UE-A的链路，但是该链路并不能反映真实的干扰水平，实际的干扰水平应该取决于干扰链路的能量测量。因此按照上述技术，当侦听链路的UE-C到UE-A的信号衰减较大时，UE-A可能无法侦听到UE-C，进而无法对UE C预留的资源进行排除，如果此时干扰链路(UE-A到UE-D，UE-C到UE-B)的信号衰减较小时，UE-A和UE-C会对彼此的接收造成干扰，即造成隐藏终端，导致干扰增强。反之当侦听链路的UE-C到UE-A的信号衰减较小时，按照上述技术，UE-A会将UE C预留的资源排除，如果此时真实的干扰链路(UE-A到UE-D，UE-C到UE-B)的信号衰减较大时，UE-A和UE-C不会对彼此的接收造成干扰，即造成暴露终端，导致资源浪费的问题。
同时，上述mode2模式也无法解决半双工的问题，即当发送UE在发送数据时无法进行资源侦听，当其他UE在也该时刻进行数据发送时，发送UE无法进行资源排除，因此可能造成资源的碰撞，增大系统的干扰。
为了解决上述问题，提高mode2资源分配的性能，进一步提出了UE协作(Inter-UE  coordination)机制，即发送UE可在其他UE(可以称为协作UE或协作终端)的协作下进行资源的选择。这里的其他UE可以是收端UE，例如图1中的UE 103或图4中的UE-B，也可以是靠近收端UE的其他UE，例如图1中的UE 104。由协作UE负责进行侦听并通过协作消息向发送UE通知侦听结果。利用协作消息，发送UE可以更加准确的确定出传输资源，减小系统的干扰，提高传输效率。具体的，协作UE可以根据发送UE预留的资源，检测该资源是否被其他UE所占用，并将检测的结果告知发送UE,发送UE可以根据协作UE提供的信息，进行资源重选。或者协作UE也可以将发送UE曾经的传输是否发生碰撞告知发送UE,发送UE可以根据协作UE提供的信息，进行对数据进行重传。
因此，需要考虑如何确定发送协作信息的资源，以及所确定的资源如何指示检测的结果。如果协作UE需要额外的资源来发送协作消息，那么，尽管协作UE机制可以提高资源选择的准确性，避免了资源的碰撞或浪费，但是协作机制同时引入了额外的信令开销，也会增大系统的干扰，造成性能的下降。并且按照现有侧行链路的传输要求，一次传输需要占用整个时隙。如果协作消息所包括的比特数量较小时，可能导致进一步的资源浪费。
本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可，例如，本申请实施例提供的方法的执行主体可以是终端设备或网络设备，或者，是终端设备或网络设备中能够调用程序并执行程序的功能模块；或者是可用于终端设备或网络设备的部件(例如芯片或者电路)。
另外，本申请的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，压缩盘(compact disc，CD)、数字通用盘(digital versatile disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(erasable programmable read-only memory，EPROM)、卡、棒或钥匙驱动器等)。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。
图5示出了本申请实施例的无线通信过程的一例的示意性交互图。图5的方法可以在协作终端(即下文中的“第一终端”，例如图1中的UE 103或104)和发送终端(即下文中的“第二终端”，例如图1中的UE 102)之间执行。
如图5所示，在S210，第一终端根据第一资源或第二资源确定第三资源，其中，所述第一资源为所述第一终端检测到的第二终端的发送资源，所述第二资源为所述第二终端的预留资源，如图6所示，第一资源在时隙上位于第三资源之前，而第二资源在时隙上位于上述第三资源之后，应理解，第一资源中还可能发送用于指示第二资源的第一信息；在本申请实施例中中，“检测”表示第一终端对第二终端的发送资源的进行侦听(sensing)或监听(monitor)的流程。后面还将结合图7-图19的例子，对第一资源、第二资源和第三资源的具体实例进行详细描述。
应理解，在本申请实施例中，协作终端可以是接收终端，如图1中的终端103，或靠近接收终端103的其他终端，如图1中的终端104，或者其他终端，本申请不做限制。协作终端可以协助发送终端在侧行链路资源池中确定发送终端进行sidelnk传输所需要的资 源。
在本申请实施例中，所述第二资源在时域上位于所述第一资源之后。例如，假设第二终端在时间单元n上占用第一资源进行了发送，第二终端的预留资源位于时间单元m，则时间单元m位于时间单元n之后，其中时间单元的单位可以是时隙(slot)，迷你时隙(mini-slot)，符号(symbol)或者其他单位，本申请实施例不做限制。
在本申请实施例的某些实现方式中，第一资源可以是发送终端发送第一级侧行链路控制信息(sidelink control information,SCI)的时频资源，其中第一级SCI在侧行链路控制信道PSCCH上传输。在此情况下，协作终端可根据发送终端发送第一级SCI的时频资源确定所述第三资源。
在本申请实施例的其他实现方式中，第一资源可以是发送终端发送第一级侧行链路控制信息(1 stSCI)和第二级侧行链路控制信息(2 ndSCI)时频资源，其中第一级SCI在侧行链路控制信道PSCCH上传输，第二级SCI在侧行链路共享信道PSSCH上传输。在此情况下，协作终端可根据该发送终端发送第一级SCI的时频资源和第二级SCI的时频资源共同确定所述第三资源。
在本申请实施例的另一些实现方式中，第一资源可以是发送终端发送第一级侧行链路控制信息(1 stSCI)，第二级侧行链路控制信息(2 ndSCI)和侧行链路数据的时频资源，其中第一级SCI在侧行链路控制信道PSCCH上传输，第二级SCI在侧行链路控制信道PSSCH上传输，侧行链路数据在侧行链路共享信道PSSCH上传输。在此情况下，协作终端可根据该发送终端发送第一级SCI的时频资源，第二级SCI的时频资源和侧行链路数据的时频资源共同来确定所述第三资源。
这样，可以根据第一资源确定用于发送协作信息的第三资源，从而实现协作终端辅助发送终端确定发送资源，解决了由发送终端自己检测带来的隐藏终端或暴露终端的问题。
在本申请实施例的另一些实现方式中，可以根据发送终端的预留资源，即上述第二资源，来确定第三资源。在一种可选的实现方式中，发送终端可以在第一消息中指示预留的资源，其中该第一消息可以是上述第一级SCI，该第一级SCI在PSCCH上传输。从而协作终端可根据第二资源确定第三资源。
本申请实施例的另一些实现方式中，第一消息可以是上述第一级SCI和/或第二级SCI，其中，第一级SCI在PSCCH上传输，第二级SCI在PSSCH上传输。发送终端在第一消息中指示预留的资源，即第二资源，协作终端根据第二资源确定所述第三资源。
本申请实施例的另一些实现方式中，第一消息可以是上述第一级SCI，第二级SCI和侧行链路数据中的部分或全部，其中第一级SCI在PSCCH上传输，第二级SCI在PSSCH上传输。发送终端在第一消息中指示预留的资源，即第二资源，协作终端根据第二资源确定所述第三资源。
这样，可以根据第二资源确定用于发送协作信息的第三资源，从而实现协作终端辅助发送终端确定发送资源，解决了由发送终端自己检测带来的隐藏终端或暴露终端的问题。
应理解，当第一资源为发送终端发送第一级侧行链路控制消息(1 stSCI)的时频资源时，第一资源的时频位置可以由配置信息确定。其中第一资源的时频位置可以预配置在终端设备，也可以由网络设备通过配置信令下发给终端设备。其中配置信令可以为系统消息块(system information block,SIB)、无线资源控制(radio resource control,RRC)信令或物 理层控制信息。第二终端接收第一级SCI的时频资源即为第一资源，此时的的第一级SCI可以认为是一个单独的SCI(stand-alone SCI)。
当第一资源为发送终端发送第一级侧行链路控制消息(1 stSCI)的时频资源和第二级侧行链路控制消息(2 ndSCI)的时频资源时，第一资源的时频位置可以通过SCI中的时频资源分配字段“Frequency resource assignment”和“Time resource assignment”来指示。
当第一资源为发送终端发送第一级侧行链路控制消息(1 stSCI)的时频资源，第二级侧行链路控制消息(2 ndSCI)的时频资源和侧行链路数据的时频资源时，第一资源的时频位置可以通过SCI中的时频资源分配字段“Frequency resource assignment”和“Time resource assignment”来指示。
应理解，第二资源的时频位置可以通过SCI中的时频资源分配字段“Frequency resource assignment”和“Time resource assignment”来指示，资源预留周期可以通过SCI中的字段"Resource reservation period"来指示。第一终端根据来自第二终端的SCI中指示的预留时频资源相关的信息确定第二终端的预留资源，其中预留资源可以是周期性的或非周期性的。
应理解，第二终端的预留资源是指第二终端未来在该资源上进行信息传输的资源，作为示例而非限定，其也可以描述为第二终端预留的发送资源或者第二终端未来的接收资源。
在S220，第一终端在第三资源上向第二终端发送协作信息；
应理解，在本申请实施例中，协作终端还可以根据第一资源或第二资源是否发生以下情形中的部分或全部来确定协作信息。
第一种：第一资源或第二资源与其他UE的传输发送资源冲突或第二终端在第一资源上的传输失败。
第二种：第二终端在第一资源上的传输失败。
在本申请实施例中，资源冲突包括资源碰撞或半双工。资源碰撞表示资源在时域和频域上同时重叠；半双工表示某个终端在同一个时域资源上同时收发，此时该终端的发送资源和接收资源在时域上重叠。
应理解，如图7中所示，在本申请实施例中，当资源池包括的总资源块RB数不能整除每个子信道包括的RB个数，会有一些RB剩余出来，即未被使用，这些剩余的PRB可以用作发送第三资源。在此情况下，可以利用资源池中剩余的未被利用的RB来发送协作信息，而无需额外分配资源，能减少协作信息所需的资源开销。
协作终端使用未被使用的资源块PRB传输协作消息，其中，该协作消息包括冲突指示或传输失败指示，其所包括的比特数较少，可以利用资源池中剩余的RB进行发送。
应理解，在本申请实施例中，发送UE可以根据协作信息，确定或重新选择发送资源或者进行数据重传。
可选地，当协作消息指示的资源未发生冲突或者未发生传输失败，则发送UE确定资源为发送资源，无需进行资源重选或数据重传。
可选的，当协作信令指示资源被其他UE占用，或者上次的传输失败，则发送UE可以重新进行资源选择进行信息传输。
根据本申请的技术方案，协作UE利用侧行链路sidelink资源池内剩余的资源块PRB来传输协作信令，协助发送UE确定传输资源，能够更加准确的确定出传输资源，降低对侧行链路传输的干扰，提升系统传输的可靠性。
如上所述，本申请实施例利用侧行链路资源池中未被使用的资源传输上述协作信息。例如，当资源池包括的总资源块RB个数不能整除每个子信道包括的RB个数，会有一些RB剩余出来。由于现有技术中sidelink的传输是以子信道为单位，一个子信道包含固定个数的RB，因此上述剩余的RB没有包括在任意一个子信道内，即上述剩余的物理资源块未被使用，这些剩余的一个或多个RB可以用于发送协作资源。剩余的RB的个数N可以由资源池包括的RB的总数对资源池内每个子信道包括的RB总数求模运算确定，例如N＝N PRBmodn subCHsize，其中N PRB表示资源池包括的RB的总数，n subCHsize表示每个子信道包括的RB总数。
如图7中所示，假设资源池包括的RB总数为54，每个子信道包括12个RB，则floor(54/12)＝4，mod(54/12)＝6。该资源池一共包括4个子信道，还有6个RB被剩余，因此协作终端可以利用上述剩余的RB传输协作信息。应理解，上述剩余RB的方式仅仅是示例性的，如果由于其他原因导致资源池中的部分资源(如RB)未被利用，也可以用于用于传输协作消息。
在本申请实施例中，侧行链路资源池中剩余的RB可以是资源池中索引最靠后的N个PRB，或者是资源池中索引最靠前的N个RB，或者资源池中中间的N个RB。剩余的RB还可以是频域上连续的或者不连续的N个RB。剩余的PRB的具体位置和/或在频域上是否连续可以预配置在终端设备，也可以由网络设备通过配置信令下发给终端设备。其中配置信令可以为系统消息块SIB、无线资源控制RRC信令或物理层控制信息。
在本申请实施例中，协作资源可以由第一资源确定，其中，第一资源表示第二终端的发送资源。第一终端确定所述第一资源与第一候选协作资源相关，所述第一候选协作资源为位于第一时隙之后且与所述第一时隙间隔大于或等于K1个时隙的第一个所述候选协作资源，所述第一时隙为第一资源所在的时隙。
具体地，第一终端首先根据第一资源确定发送协作消息的第一候选协作资源，其中第一候选协作资源属于资源池除子信道包含的RB之外剩余的N个RB。第一候选协作资源的具体确定方式如下：
将侧行链路资源池中剩余的N个物理资源块在时域上按照第一时长N_P分为至少一组，其中每组物理资源块对应一个候选协作资源，相邻的两个候选协作资源之间间隔第一时长，即第一时长为候选协作资源的周期。每个候选协作资源包括的时隙的个数M大于等于1，小于或等于第一时长N_P。资源池内的第k个时隙为一个候选协作资源的起始位置，k mod N_P＝0。具体地，如图8所示，当第一时长N_P＝4，即候选协作资源的周期为4，一个候选协作资源包括M＝2个时隙，图8中包括3个候选协作资源。
由第一资源确定的第一候选协作资源为位于第一时隙之后且与第一时隙间隔大于或等于K1个时隙的第一个候选协作资源，其中第一时隙为第一资源所在的时隙。具体地，上述第一候选协作资源的位置由候选协作资源的起始时隙确定。即要保证第一候选协作资源的起始时隙位于第一时隙之后，并且第一候选协作资源的起始时隙与第一时隙间隔大于或等于K1个时隙，同时满足上述两个条件的在时间上最靠前的第一个候选协作资源即为第一候选协作资源。
作为另一个例子，上述间隔K1也可以用符号作为单位。具体的，由第一资源确定的第一候选协作资源为位于第一符号之后且与第一符号间隔大于或等于K1个符号的第一个 候选协作资源，其中第一符号为第一资源所在的时隙的第一个或最后一个符号。具体地，上述第一候选协作资源的位置由候选协作资源的起始符号确定。即要保证第一候选协作资源的起始符号位于第一符号之后，并且第一候选协作资源的起始符号与第一符号间隔大于或等于K1个符号，同时满足上述两个条件的在时间上最靠前的第一个候选协作资源即为第一候选协作资源。
具体地，在图8的例子中，候选协作资源的周期为N_P＝4，一个候选协作资源包括M＝2个时隙。候选协作资源与第一资源的间隔K1＝2。当第二终端分别在时隙1,2,3,4上进行发送时，即第一资源占用的时隙分别为1,2,3,4。与时隙1,2,3,4间隔K1＝2个时隙的时隙为3,4,5,6，起始位置位于上述时隙之后的第一个候选协作资源为起始位置为时隙6的候选协作资源。因此，第二终端在时隙1,2,3,4上的发送的第一资源对应的候选协作资源位于时隙6和时隙7。同理，如图8所示，当第二终端在时隙5,6,7,8上进行发送时，对应的候选协作资源位于时隙10和时隙11。
作为另一个例子，在本申请实施例中，第一终端还根据第一候选协作资源确定第一资源集合。第一资源集合内包括的资源对应的协作资源为第一候选协作资源。第一资源集合包括的资源可以按照第一资源单元的粒度进行划分并编号。
例如第一资源单元的粒度为时域上的一个时隙以及频域上的一个子信道。如图9所示，第一资源集合包括16个第一资源单元，每个第一资源单元在时域上的占用一个时隙，在频域上占用一个子信道。第一资源包括第一资源集合中的一个或多个第一资源单元。例如，当第二终端在时隙1上的第一个和第二个子信道发送时，第一资源包括第一资源单元1和第一资源单元2。可以按照一定顺序将第一资源集合内包括的全部第一资源单元排序，排序后的每个第一资源单元对应一个索引。
作为另一个例子，本申请实施例中，第一候选协作资源包括的协作资源也可以按照第三资源单元的粒度进行划分，例如第三资源单元的粒度为时域上的一个时隙以及频域上的一个资源块。如图9所示，第一候选协作资源包括16个第三资源单元，每个第三资源单元在时域上的占用一个时隙，在频域上占用一个资源块。可以按照一定顺序将第一候协作资源内包括的全部第三资源单元排序，排序后的每个第三资源单元对应一个索引。
其中，上述第三单元的时隙也可以是一个迷你时隙。
将排序后的第一资源集合中的第一资源单元与第一候选协作资源中的第三资源单元一一对应。一个第一资源单元对应的第三资源单元的个数为floor(N3/N1)。其中N1为第一资源集合中包括的第一资源单元的总数，N3为第一候选协作资源中包括的第三资源单元的总数。具体的对应关系可以分为以下几种：
当第一资源集合中的包括的第一资源单元的个数等于第一候选协作资源包括的第三资源单元时，则N1＝N3，floor(N3/N1)＝1。对应关系为一对一，即第一资源集合中的一个第一资源单元对应第一候选协作资源中的一个第三资源单元。如图9所示，第一资源集合包括16个第一资源单元，第一候选协作资源包括16个第三资源单元，排序后的每个第一资源单元对应一个索引，排序后的每个第三资源单元对应一个索引，一个第一资源单元对应一个第三资源单元。图9中的数字表示第一资源单元或第三资源单元的索引。则索引为0的第一资源单元对应索引为0的第三资源单元，索引为1的第一资源单元对应索引为1的第三资源单元，以此类推。
当第一资源集合中的包括的第一资源单元的个数小于第一候选协作资源包括的第三资源单元时，则N1<N3，floor(N3/N1)≥1。对应关系为一对多或一对一，即第一资源集合中的一个第一资源单元对应第一候选协作资源中的多个第三资源单元；如图10所示，第一资源集合包括8个第一资源单元，第一候选协作资源包括16个第三资源单元，排序后的每个第一资源单元对应一个索引，排序后的每个第三资源单元对应一个索引，一个第一资源单元对应多个第三资源单元。图10中的数字表示第一资源单元或第三资源单元的索引。则索引为0的第一资源单元对应索引为0的第三资源单元和索引为1的第三资源单元，索引为1的第一资源单元对应索引为2的第三资源单元和索引为3的第三资源单元，以此类推。
当第一资源集合中的包括的第一资源单元的个数大于第一候选协作资源包括的第三资源单元时，则N1>N3，floor(N3/N1)≤1。对应关系为多对一或一对一，即第一资源集合中的多个第一资源单元对应第一候选协作资源中的一个第三资源单元，一个第三资源单元对应的第一资源单元的个数为floor(N3/N1)。如图11所示，第一资源集合包括16个第一资源单元，第一候选协作资源包括8个第三资源单元，排序后的每个第一资源单元对应一个索引，排序后的每个第三资源单元对应一个索引，多个第一资源单元对应一个第三资源单元。图11中的数字表示第一资源单元或第三资源单元的索引。则索引为0的第一资源单元和索引为1的第一资源单元对应索引为0的第三资源单元，索引为2的第一资源单元和索引为3的第一资源单元对应索引为1的第三资源单元，以此类推。
此外，在本申请实施例中，第一资源集合内包括的全部第一资源单元的可以按照先频域后时域的顺序编号，如图9所示，第一资源集合包括16个第一资源单元，每个第一资源单元在时域上的占用一个时隙，在频域上占用一个子信道，索引为0-3的第一资源单元位于时隙0，索引为4-7的第一资源单元位于时隙1，索引为8-11的第一资源单元位于时隙2，索引为12-15的第一资源单元位于时隙3。
或者，第一资源集合内包括的全部第一资源单元的可以按照先时域后频域的顺序编号，如图12所示，第一资源集合包括16个第一资源单元，每个第一资源单元在时域上的占用一个时隙，在频域上占用一个子信道，索引为0-3的第一资源单元位于子信道0，索引为4-7的第一资源单元位于子信道1，索引为8-11的第一资源单元位于子信道2，索引为12-15的第一资源单元位于子信道3。
同样的，第一候选协作资源集合内包括的全部第三资源单元的可以按照先频域后时域的顺序编号，或者第一候选协作资源集合内包括的全部第三资源单元的也可以按照先时域后频域的顺序编号。具体的示例与图9与图12类似。
根据第一资源集合中的每个第一资源单元与第一候选协作资源中的每个第三资源单元的对应关系，可以确定第一资源在第一候选协作资源对应的第三资源。具体地，根据第一资源包括的第一资源单元的索引，确定与其对应的资源单元的索引。
如图9所示，第一资源集合包括16个第一资源单元，每个第一资源单元在时域上的占用一个时隙，在频域上占用一个子信道。第一资源包括第一资源单元1和第一资源单元2。第一候选协作资源包括16个第三资源单元，每个第三资源单元在时域上的占用一个时隙，在频域上占用一个资源块。由于第一资源集合中的包括的第一资源单元的个数等于第一候选协作资源包括的第三资源单元时，对应关系为一对一，即第一资源集合中的一个第 一资源单元对应第一候选协作资源中的一个第三资源单元。假设第一资源集合内包括的全部第一资源单元的按照先频域后时域的顺序编号，第一候选协作资源集合内包括的全部第三资源单元的也按照先频域后时域的顺序编号。则第一资源包括的索引为0的第一资源单元对应第一候选协作资源中的索引为0的第三资源单元，第一资源包括的索引为1的第一资源单元对应第一候选协作资源中的索引为1的第三资源单元。即第三资源为第一候选协作资源中包括的索引为0的第三资源单元和索引为1的第三资源单元。
在本申请实施例中，第一终端还可以根据第一资源和第一标识确定第三资源，第一标识为第一终端的标识和/或第二终端的标识。具体的，根据第一资源，可以在第一候选协作资源中对应至少一个第三资源单元，每个第三资源单元可以对应至少一对序列，所述至少一个第三资源单元包括的每对序列对应不同的循环偏移值。第一资源对应的全部第三资源单元包括的所有序列对可以按照先频域，再时域，最后按照每个第三资源单元包括的序列对个数进行排序，每个排序后的序列对会对应一个索引。第一终端可以根据第一终端的设备标识和/或第二终端的设备标识确定发送协作消息的序列对索引，该序列对索引所对应的第三资源单元和循环偏移值即为第三资源。例如，第一终端发送协作消息的序列对索引可以由(S ID+C ID)modR PRB,CS，其中C ID为第一终端的设备标识，S ID为第二终端的设备标识，R PRB,CS为第三资源包括的所有序列对的总数。如图13所示，第一资源集合包括16个第一资源单元，每个第一资源单元在时域上的占用一个时隙，在频域上占用一个子信道。第一资源包括第一资源单元0和第一资源单元1。第一候选协作资源包括16个第三资源单元，每个第三资源单元在时域上的占用一个时隙，在频域上占用一个资源块。第一资源集合中的包括的第一资源单元的个数等于第一候选协作资源包括的第三资源单元，则第一资源集合中的一个第一资源单元对应第一候选协作资源中的一个第三资源单元。假设第一资源集合内包括的全部第一资源单元的按照先频域后时域的顺序编号，第一候选协作资源集合内包括的全部第三资源单元的也按照先频域后时域的顺序编号。则第一资源对应第一候选协作资源中索引为0的第三资源单元和第一候选协作资源中索引为1的第三资源单元。假设每个第三资源单元上有6个序列对，将索引为0的第三资源单元和索引为1的第三资源单元包括的所有序列对按照先频域，再时域，最后按照每个第三资源单元包括的序列对个数进行排序，得到2*6＝12个序列对，即R PRB,CS＝12。假设第一终端和第二终端的设备标识分别由4比特标识，例如，第一终端的设备标识C ID＝0010，第二终端的设备标识S ID＝1010，第三资源对应的序列索引为(S ID+C ID)modR PRB,CS＝(0010+1010)mod 12＝8，第一终端在索引为0的第三资源单元上用索引为8的序列对进行发送协作消息。
此外，在本申请实施例中的另外一种实现方式中，当每个第三资源单元上包括多个序列对时，还可以将第一候选协作资源集合内包括的全部序列对按照先频域，再时域，最后按照每个第三资源单元包括的序列对个数进行统一排序，每个排序后的序列对会对应一个索引。
或者第一候选协作资源集合内包括的全部序列对也可以按照先时域，再频域，最后按照每个第三资源单元包括的序列对个数进行统一排序，每个排序后的序列对会对应一个索引。
上述频域，时域，序列域的排序方式可以任意调整，本申请不做限制。
如图14所示，第一候选协作资源包括16个第三资源单元，每个第三资源单元在时域 上的占用一个时隙，在频域上占用一个资源块，每个第三资源单元上有2个序列对。将第一候选协作资源集合内包括的全部序列对按照先频域，再时域，最后按照每个第三资源单元包括的序列对个数进行统一排序。图14中的数字表示第一候选协作资源集合内包括的全部序列对的索引。
将排序后的第一资源集合中的第一资源单元与第一候选协作资源中的序列对一一对应。一个第一资源单元对应的序列对的个数为floor(N4/N1)。其中N1为第一资源集合中包括的第一资源单元的总数，N4为第一候选协作资源中包括的序列对的总数。具体的对应关系可以分为以下几种：
当第一资源集合中的包括的第一资源单元的个数等于第一候选协作资源包括的全部序列对时，则N1＝N4，floor(N4/N1)＝1。对应关系为一对一，即第一资源集合中的一个第一资源单元对应第一候选协作资源中的一个序列对。
当第一资源集合中的包括的第一资源单元的个数小于第一候选协作资源包括的区别序列对时，则N1<N4，floor(N4/N1)≥1。对应关系为一对多或一对一，即第一资源集合中的一个第一资源单元对应第一候选协作资源中的多个序列对；如图14所示，第一资源集合包括16个第一资源单元，第一候选协作资源包括32个序列对，排序后的每个第一资源单元对应一个索引，排序后的每个序列对对应一个索引，一个第一资源单元对应一个序列对。图14中的数字表示第一资源单元或序列对的索引。则索引为0的第一资源单元对应索引为0的和索引为1的序列对，以此类推。
当第一资源集合中的包括的第一资源单元的个数大于第一候选协作资源包括的第三资源单元时，则N1>N4，floor(N4/N1)≤1。对应关系为多对一或一对一，即第一资源集合中的多个第一资源单元对应第一候选协作资源中的一个序列对，一个序列对对应的第一资源单元的个数为floor(N4/N1)。
根据本申请的技术方案，协作UE利用侧行链路sidelink资源池内剩余的资源块PRB来传输协作信令，协助发送UE确定传输资源，能够更加准确的确定出传输资源，降低对侧行链路传输的干扰，提升系统传输的可靠性。
在本申请实施例中，协作资源还可以由第二资源确定，其中，第二资源表示第二终端的发送资源。第一终端确定所述第二资源与第一候选协作资源相关，所述第一候选协作资源为位于第一时隙之前且与所述第一时隙间隔大于或等于K2个时隙的第一个所述候选协作资源，所述第一时隙为第二资源所在的时隙。
具体地，第一终端首先根据第二资源确定发送协作消息的第一候选协作资源，其中第一候选协作资源属于资源池除子信道包含的RB之外剩余的N个RB。第一候选协作资源的具体确定方式如下：
将侧行链路资源池中剩余的N个物理资源块在时域上按照第一时长N_P分为至少一组，其中每组物理资源块对应一个候选协作资源，相邻的两个候选协作资源之间间隔第一时长，即第一时长为候选协作资源的周期。每个候选协作资源包括的时隙的个数M大于等于1，小于或等于第一时长N_P。资源池内的第k个时隙为一个候选协作资源的起始位置，k mod N_P＝0。具体地，如图15所示，当第一时长N_P＝4，即候选协作资源的周期为4，一个候选协作资源包括M＝2个时隙，图15中包括3个候选协作资源。
由第二资源确定的第一候选协作资源为位于第一时隙之前且与第一时隙间隔大于或 等于K2个时隙的第一个候选协作资源，其中第一时隙为第二资源所在的时隙。具体地，上述第一候选协作资源的位置由候选协作资源的起始时隙确定。即要保证第一候选协作资源的起始时隙位于第一时隙之前，并且第一候选协作资源的起始时隙与第一时隙间隔大于或等于K2个时隙，同时满足上述两个条件的在时间上最靠前的第一个候选协作资源即为第一候选协作资源。
作为另一个例子，上述间隔K2也可以用符号作为单位。具体的，由第一资源确定的第一候选协作资源为位于第一符号之前且与第一符号间隔大于或等于K2个符号的第一个候选协作资源，其中第一符号为第一资源所在的时隙的第一个或最后一个符号。具体地，上述第一候选协作资源的位置由候选协作资源的起始符号确定。即要保证第一候选协作资源的起始符号位于第一符号之后，并且第一候选协作资源的起始符号与第一符号间隔大于或等于K2个符号，同时满足上述两个条件的在时间上最靠前的第一个候选协作资源即为第一候选协作资源。
具体地，在图15的例子中，候选协作资源的周期为N_P＝4，一个候选协作资源包括M＝2个时隙。候选协作资源与第二资源的间隔K2＝2。当第二终端分别在时隙5,6,7,8上进行发送时，即第二资源占用的时隙分别为5,6,7,8。与时隙5,6,7,8间隔K2＝2个时隙的时隙为3,4,5,6，起始位置位于上述时隙之后的第一个候选协作资源为起始位置为时隙2的候选协作资源。因此，第二终端在时隙5,6,7,8上的发送的第二资源对应的候选协作资源位于时隙2和时隙3。同理，如图15所示，当第二终端在时隙9,10,11,12上进行发送时，对应的候选协作资源位于时隙6和时隙7。
作为另一个例子，在本申请实施例中，第一终端还根据第一候选协作资源确定第二资源集合。第二资源集合内包括的资源对应的协作资源为第一候选协作资源。第二资源集合包括的资源可以按照第二资源单元的粒度进行划分并编号。
例如第二资源单元的粒度为时域上的一个时隙以及频域上的一个子信道。如图16所示，第二资源集合包括16个第二资源单元，每个第二资源单元在时域上的占用一个时隙，在频域上占用一个子信道。第二资源包括第二资源集合中的一个或多个第二资源单元。例如，当第二终端在时隙1上的第一个和第二个子信道发送时，第二资源包括第二资源单元1和第二资源单元2。可以按照一定顺序将第二资源集合内包括的全部第二资源单元排序，排序后的每个第二资源单元对应一个索引。
作为另一个例子，本申请实施例中，第一候选协作资源包括的协作资源也可以按照第三资源单元的粒度进行划分，例如第三资源单元的粒度为时域上的一个时隙以及频域上的一个物理资源块。如图16所示，第一候选协作资源包括16个第三资源单元，每个第三资源单元在时域上的占用一个时隙，在频域上占用一个物理资源块。可以按照一定顺序将第一候协作资源内包括的全部第三资源单元排序，排序后的每个第三资源单元对应一个索引。
将排序后的第二资源集合中的第二资源单元与第一候选协作资源中的第三资源单元一一对应。一个第二资源单元对应的第三资源单元的个数为floor(N3/N1)。其中N1为第二资源集合中包括的第二资源单元的总数，N3为第一候选协作资源中包括的第三资源单元的总数。具体的对应关系可以分为以下几种：
当第二资源集合中的包括的第二资源单元的个数等于第一候选协作资源包括的第三资源单元时，则N1＝N3，floor(N3/N1)＝1。对应关系为一对一，即第二资源集合中的 一个第二资源单元对应第一候选协作资源中的一个第三资源单元。如图16所示，第二资源集合包括16个第二资源单元，第一候选协作资源包括16个第三资源单元，排序后的每个第二资源单元对应一个索引，排序后的每个第三资源单元对应一个索引，一个第二资源单元对应一个第三资源单元。图16中的数字表示第二资源单元或第三资源单元的索引。则索引为0的第二资源单元对应索引为0的第三资源单元，索引为1的第二资源单元对应索引为1的第三资源单元，以此类推。
当第二资源集合中的包括的第二资源单元的个数小于第一候选协作资源包括的第三资源单元时，则N1<N3，floor(N3/N1)≥1。对应关系为一对多或一对一，即第二资源集合中的一个第二资源单元对应第一候选协作资源中的多个第三资源单元；如图17所示，第二资源集合包括8个第二资源单元，第一候选协作资源包括17个第三资源单元，排序后的每个第二资源单元对应一个索引，排序后的每个第三资源单元对应一个索引，一个第二资源单元对应多个第三资源单元。图17中的数字表示第二资源单元或第三资源单元的索引。则索引为0的第二资源单元对应索引为0的第三资源单元和索引为1的第三资源单元，索引为1的第二资源单元对应索引为2的第三资源单元和索引为3的第三资源单元，以此类推。
当第二资源集合中的包括的第二资源单元的个数大于第一候选协作资源包括的第三资源单元时，则N1>N3，floor(N3/N1)≤1。对应关系为多对一或一对一，即第二资源集合中的多个第二资源单元对应第一候选协作资源中的一个第三资源单元，一个第二资源单元对应的第三资源单元的个数为floor(N3/N1)。如图18所示，第二资源集合包括16个第二资源单元，第一候选协作资源包括8个第三资源单元，排序后的每个第二资源单元对应一个索引，排序后的每个第三资源单元对应一个索引，多个第二资源单元对应一个第三资源单元。图18中的数字表示第二资源单元或第三资源单元的索引。则索引为0的第二资源单元和索引为1的第二资源单元对应索引为0的第三资源单元，索引为2的第二资源单元和索引为3的第二资源单元对应索引为1的第三资源单元，以此类推。
此外，在本申请实施例中，第二资源集合内包括的全部第二资源单元的可以按照先频域后时域的顺序编号，如图16所示，第二资源集合包括16个第二资源单元，每个第二资源单元在时域上的占用一个时隙，在频域上占用一个子信道，索引为0-3的第二资源单元位于时隙0，索引为4-7的第二资源单元位于时隙1，索引为8-11的第二资源单元位于时隙2，索引为12-15的第二资源单元位于时隙3。
或者，第二资源集合内包括的全部第二资源单元的可以按照先时域后频域的顺序编号，如图19所示，第二资源集合包括16个第二资源单元，每个第二资源单元在时域上的占用一个时隙，在频域上占用一个子信道，索引为0-3的第二资源单元位于子信道0，索引为4-7的第二资源单元位于子信道1，索引为8-11的第二资源单元位于子信道2，索引为12-15的第二资源单元位于子信道3。
同样的，第一候选协作资源集合内包括的全部第三资源单元的可以按照先频域后时域的顺序编号，或者第一候选协作资源集合内包括的全部第三资源单元的也可以按照先时域后频域的顺序编号。具体的示例与图16与图19类似。
根据第二资源集合中的每个第二资源单元与第一候选协作资源中的每个第三资源单元的对应关系，可以确定第二资源在第一候选协作资源对应的第三资源。具体地，根据第 二资源包括的第二资源单元的索引，确定与其对应的资源单元的索引。
如图16所示，第二资源集合包括16个第二资源单元，每个第二资源单元在时域上的占用一个时隙，在频域上占用一个子信道。第二资源包括第二资源单元1和第二资源单元2。第一候选协作资源包括16个第三资源单元，每个第三资源单元在时域上的占用一个时隙，在频域上占用一个物理资源块。由于第二资源集合中的包括的第二资源单元的个数等于第一候选协作资源包括的第三资源单元时，对应关系为一对一，即第二资源集合中的一个第二资源单元对应第一候选协作资源中的一个第三资源单元。假设第二资源集合内包括的全部第二资源单元的按照先频域后时域的顺序编号，第一候选协作资源集合内包括的全部第三资源单元的也按照先频域后时域的顺序编号。则第二资源包括的索引为0的第二资源单元对应第一候选协作资源中的索引为0的第三资源单元，第二资源包括的索引为1的第二资源单元对应第一候选协作资源中的索引为1的第三资源单元。即第三资源为第一候选协作资源中包括的索引为0的第三资源单元和索引为1的第三资源单元。
在本申请实施例中，第一终端还可以根据第二资源和第一标识确定第三资源，第一标识为第一终端的标识和/或第二终端的标识。具体的，根据第二资源可以在第一候选协作资源中对应至少一个第三资源单元，每个第三资源单元可以对应至少一对序列，所述至少一个第三资源单元包括的每对序列对应不同的循环偏移值。第二资源对应的全部第三资源单元包括的所有序列对可以按照先频域，再时域，最后按照每个第三资源单元包括的序列对个数进行排序，每个排序后的序列对会对应一个索引。第一终端可以根据第一终端的设备标识和/或第二终端的设备标识确定发送协作消息的序列对索引，该序列对索引所对应的第三资源单元和循环偏移值即为第三资源。例如，第一终端发送协作消息的序列对索引可以由(S ID+C ID)modR PRB,CS，其中C ID为第一终端的设备标识，S ID为第二终端的设备标识，R PRB,CS为第三资源包括的所有序列对的总数。如图20所示，第二资源集合包括16个第二资源单元，每个第二资源单元在时域上的占用一个时隙，在频域上占用一个子信道。第二资源包括第二资源单元0和第二资源单元1。第一候选协作资源包括16个第三资源单元，每个第三资源单元在时域上的占用一个时隙，在频域上占用一个物理资源块PRB。第二资源集合中的包括的第二资源单元的个数等于第一候选协作资源包括的第三资源单元，则第二资源集合中的一个第二资源单元对应第一候选协作资源中的一个第三资源单元。假设第二资源集合内包括的全部第二资源单元的按照先频域后时域的顺序编号，第一候选协作资源集合内包括的全部第三资源单元的也按照先频域后时域的顺序编号。则第二资源对应第一候选协作资源中索引为0的第三资源单元和第一候选协作资源中索引为1的第三资源单元。假设每个第三资源单元上有6个序列对，将索引为0的第三资源单元和索引为1的第三资源单元包括的所有序列对按照先频域，再时域，最后按照每个第三资源单元包括的序列对个数进行排序，得到2*6＝12个序列对，即R PRB,CS＝12。假设第一终端和第二终端的设备标识分别由4比特标识，例如，第一终端的设备标识C ID＝0010，第二终端的设备标识S ID＝1010，第三资源对应的序列索引为(S ID+C ID)modR PRB,CS＝(0010+1010)mod 12＝8，第一终端在索引为0的第三资源单元上用索引为8的序列对进行发送协作消息。
此外，在本申请实施例中的另外一种实现方式中，当每个第三资源单元上包括多个序列对时，还可以将第一候选协作资源集合内包括的全部序列对按照先频域，再时域，最后按照每个第三资源单元包括的序列对个数进行统一排序，每个排序后的序列对会对应一个 索引。
根据第二资源集合中的每个第二资源单元与第一候选协作资源中的每个序列对的对应关系，可以确定第二资源在第一候选协作资源对应的第三资源。具体地，根据第二资源包括的第二资源单元的索引，确定与其对应的序列对的索引。
可选的，第一终端还可以根据第二资源和第一标识确定第三资源，第一标识为第一终端的标识和/或第二终端的标识。
具体的方式与根据第一资源确定第三资源的方式类似，区别在于将第一资源，第一资源集合，第一资源单元替换为第二资源，第二资源集合，第二资源单元，这里不再赘述。
根据本申请的技术方案，协作UE利用侧行链路sidelink资源池内剩余的资源块PRB来传输协作信令，协助发送UE确定传输资源，能够更加准确的确定出传输资源，降低对侧行链路传输的干扰，提升系统传输的可靠性。
图21出了本申请的无线通信过程的另一例的示意性交互图。
如图21所示，情形一，在S310，第一终端从第二终端接收第一信息，所述第一信息用于指示第一资源和/或第二资源。
应理解，在本申请实施例中，第一终端为协作终端，第二终端为发送终端，其中，协作终端可以是接收终端，或靠近接收终端的其他终端，或者其他终端，本申请实施例不做限制。协作终端可以协助发送终端在侧行链路资源池中确定发送终端进行sidelnk传输所需要的资源。
情形一可包括以下几种实现方式。
可选地，在本申请实施例的某些实现方式中，第一终端从第二终端接收第一信息，第一信息为第一级侧行链路控制信息(1 stSCI)和第二级侧行链路控制信息(2 ndSCI)，第一信息指示第一资源。第一资源为第二终端发送第一级侧行链路控制信息(1 stSCI)和第二级侧行链路控制信息(2 ndSCI)的时频资源，其中第一级SCI在PSCCH上传输，第二级SCI在PSSCH上传输。
可选地，在本申请实施例的某些实现方式中，第一终端从第二终端接收第一信息，第一信息为第一级侧行链路控制信息(1 stSCI)和第二级侧行链路控制信息(2 ndSCI)，第一信息指示第一资源。第一资源为第二终端发送第一级侧行链路控制信息(1 stSCI)，第二级侧行链路控制信息(2 ndSCI)和侧行链路数据的时频资源，其中第一级SCI在PSCCH上传输，第二级SCI在PSSCH上传输，侧行链路数据在PSSCH上传输。
可选地，在本申请实施例的某些实现方式中，第一终端从第二终端接收第一信息，第一信息为第一级侧行链路控制信息(1 stSCI)，第一信息指示第二资源。第二资源为第二终端的预留资源。其中第一级SCI在PSCCH上传输，
可选地，在本申请实施例的某些实现方式中，第一终端从第二终端接收第一信息，第一信息为第一级侧行链路控制信息(1 stSCI)和第二级侧行链路控制信息(2 ndSCI)，第一信息指示第一资源和/或第二资源。第一资源为第二终端发送第一级侧行链路控制信息(1 stSCI)，第二级侧行链路控制信息(2 ndSCI)的时频资源，第二资源为第二终端的预留资源。其中第一级SCI在PSCCH上传输，第二级SCI在PSSCH上传输。

情形二，在S320，第一终端在第一资源上接收第一消息。
情形二可包括以下几种实现方式。
可选地，在本申请实施例的某些实现方式中，第一终端从第二终端接收第一信息，第一信息为第一级SCI，第一资源为第二终端发送第一级SCI的时频资源，其中第一级SCI在PSCCH上传输。在这种情形下，第二终端不需要指示第一资源，第一资源的时频位置可以由配置信息确定。其中第一资源的时频位置可以预配置在终端设备，也可以由网络设备通过配置信令下发给终端设备。其中配置信令可以为系统消息块SIB、无线资源控制RRC信令或物理层控制信息。第二终端接收第一级SCI的时频资源即为第一资源。
在S330，第二设备根据第一信息，确定第一资源和/或第二资源发生资源冲突。
其中，第一资源和/或第二资源发生资源冲突包括以下几种情况：
情形a
第一资源与第四资源冲突，其中，第四资源表示第三终端的发送资源，即第三终端在第四资源上进行过传输，第三终端为所述第一终端和所述第二终端之外的其他终端。
其中，第一资源可能与第四资源发生的资源冲突可分为资源碰撞或者半双工，所述资源碰撞表示第一终端和第三终端在同一资源块上进行信息传输，即第一资源与第四资源在时域和频域上同时重叠。所述半双工表示某个终端在同一个时域资源上同时收发，此时该终端的发送资源和接收资源在时域上重叠。
例如，第二终端发给第三终端，而第三终端发给其他终端，此时第三终端同时收发，对第二终端的传输影响为，第二终端设备的接收终端无法正常接收。
或者，第三终端发给第二终端，而第二终端发给其他终端，此时，第二终端同时收发，对第二终端的传输影响为，第二终端无法接收第三终端的信息。
情形b
第二资源与第四资源冲突，其中，第四资源表示第三终端的预留资源，即第三终端预留了在第二资源上传输，第三终端为所述第一终端和所述第二终端之外的其他终端。
其中，第一资源可能与第四资源发生的资源冲突可分为资源碰撞或者半双工，所述资源碰撞表示第一终端和第三终端在同一资源块上进行信息传输，即第一资源与第四资源在时域和频域上同时重叠。所述半双工表示某个终端在同一个时域资源上同时收发，此时该终端的发送资源和接收资源在时域上重叠。
例如，第二终端发给第三终端，而第三终端发给其他终端，此时第三终端同时收发，对第二终端的传输影响为，第二终端设备的接收终端无法正常接收。
或者，第三终端发给第二终端，而第二终端发给其他终端，此时，第二终端同时收发，对第二终端的传输影响为，第二终端无法接收第三终端的信息。
情形c
第二资源与第五资源冲突，其中，第一终端的预留的发送资源，即第一终端预留了在第五资源上发送。
其中，第二资源可能与第五资源发生的资源冲突可分为资源碰撞或者半双工，所述资源碰撞表示第一终端和第二终端在同一资源块上进行信息传输，即第一资源与第五资源在时域和频域上同时重叠。所述半双工表示某个终端在同一个时域资源上同时收发，此时该终端的发送资源和接收资源在时域上重叠。
例如，第一终端发给第二终端，而第二终端发给其他终端，此时第二终端同时收发，对第二终端的传输影响为，第二终端无法接收第一终端的信息。
或者，第二终端发给第一终端，而第一终端发给其他终端，此时，第一终端同时收发，对第二终端的传输影响为，第二终端的接收终端无法正常接收。
情形d
第二资源与第五资源冲突，其中，第一终端的期望的接收资源，即第一终端期望在第五资源上接收其他终端的信息。
其中，第二资源可能与第五资源发生的资源冲突可分为资源碰撞或者半双工，所述资源碰撞表示第一终端和其他终端在同一资源块上进行信息传输，即其他终端在第一资源与第五资源在时域和频域上同时重叠。所述半双工表示某个终端在同一个时域资源上同时收发，此时该终端的发送资源和接收资源在时域上重叠。
例如，第二终端发给其他终端，而其他终端发给第一终端，此时其他终端同时收发，对第二终端的传输影响为，第二终端的接收终端无法正常接收。
或者，其他终端发给第二终端，而第二终端发给第一终端，此时，第二终端同时收发，对第二终端的传输影响为，第二终端无法接收第三终端的信息。
在上述情形a和/或情形b中，第一终端还可以根据对第一终端和/或第三终端的RSRP测量结果确定是否发生资源冲突指示。第一终端可以在满足以下条件的情况下发送冲突指示信息：(1)第一终端确定第一资源和/或第二资源与第四资源有资源冲突；(2)第一终端确定与第三终端之间的链路上的参考信号接收功率RSRP测量值高于第一门限，或，第一终端确定第一终端与第三终端之间的链路上的RSRP测量值高于第一终端与第二终端之间的链路上的RSRP测量值。因此在第一终端发送冲突指示信息之前，还可以包括：第一终端确定与第三终端之间的链路上的参考信号接收功率RSRP测量值高于第一门限；或，第一终端确定第一终端与第三终端之间的链路上的RSRP测量值高于第一终端与第二终端之间的链路上的RSRP测量值。该种实施方式中，第一终端可以更加准确的判断资源冲突是否会对第一终端的传输造成影响。例如当RSRP的测量结果低于一定门限时，即使第一资源和/或第二资源与第四资源在时频域上发生重叠，其他终端在第四资源上的传输也不会对第二终端造成严重干扰，此时在确定有资源冲突的情况下第一终端也不向第二终端发送冲突指示信息。进一步增加传输可靠性，避免不必要的资源重选或资源放弃。
在上述情形c和/或情形d中，第一终端还可以根据对第一终端RSRP测量结果确定是否发生资源冲突指示。第一终端可以在满足以下条件的情况下发送冲突指示信息：(1)第一终端确定第二资源与第五资源有资源冲突；(2)第一终端确定与第二终端之间的链路上的参考信号接收功率RSRP测量值高于第一门限。因此在第一终端发送冲突指示信息之前，还可以包括：第一终端确定与第二终端之间的链路上的参考信号接收功率RSRP测量值高于第一门限。该种实施方式中，第一终端可以更加准确的判断资源冲突是否会对第一终端的传输造成影响。例如当RSRP的测量结果低于一定门限时，即使第二资源和第五 资源在时频域上发生重叠，第一终端或其他终端在第五资源上的传输也不会对第二终端造成严重干扰，此时在确定有资源冲突的情况下第一终端也不向第二终端发送冲突指示信息。进一步增加传输可靠性，避免不必要的资源重选或资源放弃。
在上述4种情形中，可选的，当第一终端为第二终端对应的接收终端时，其他终端与第二终端的资源冲突会直接干扰第一终端的接收，并且此时第一终端可以准确测量到其他终端到第一终端的链路上的参考信号接收功率RSRP，因此第一终端对其他终端的侦听结果可以反映真实的干扰状况，所以在这种情况下，第一终端可以在满足上述条件(1)和(2)的情况下发送冲突指示信息。当第一终端不是第二终端对应的接收终端时，第一终端只能测量到其他终端与第一终端之间的链路上的RSRP值，不能测量到其他终端与第二终端对应接收终端之间的链路上的RSRP值，因此第一终端的RSRP测量结果无法准确反映其他终端与第二终端的接收终端之间的链路上的干扰情况，所以，在这种情况下，第一终端可以仅考虑资源冲突，即第一终端在满足条件(1)的情况下发送冲突指示信息。
在本申请实施例的某些实现方式中，在S330，第一终端还可以根据第一信息，确定第一资源上的传输失败。传输失败可以根据第二终端在第一资源上的能量测量确定，具体的，第一终端可以测量第一资源上的参考信号接收功率RSRP(reference signal receiving power)，如果第一终端在第一资源上测量的RSRP低于第一门限，则表示第二终端在第一资源上的传输失败。其中第一门限可以预配置在终端设备，也可以由网络设备通过配置信令下发给终端设备。其中配置信令可以为系统消息块SIB、无线资源控制RRC信令或物理层控制信息。第二终端接收第一级SCI的时频资源即为第一资源。
可选地，第一终端还可以检测第二终端的接收终端在PSFCH资源上反馈的HARQ信息，如果第二终端的接收终端在PSFCH资源上反馈NACK，则表示第二终端在第一资源上的传输失败。当第一终端为第二终端的接收终端时，如果第一终端不能在第一资源上正确译码，则表示第二终端在第一资源上的传输失败。
在S340，在第三资源上，发送第二指示信息，用于指示第一资源/第二资源是否发生资源冲突以及在第一资源上的传输是否失败。
在本申请实施例中，第二终端接收冲突指示信息。可选的，还包括第二终端对第二资源进行重选，或丢弃第二资源上的传输。例如，第二终端接收到该冲突指示信息后，可以重选预留的资源，或者第二终端放弃预留的资源上的传输。可选的，当冲突指示信息中指示资源冲突类型为半双工时，第二终端可以有以下几种操作：1)第二终端重选第二资源，并且在进行资源重选时，重选的资源时需要避免与之前第二资源有时域重叠，也就是说重选的资源必须与第二资源位于不同的时间单元(例如时隙，符号，迷你时隙等)中；2)第二终端不在第二资源上发送数据，但是在第二资源上接收数据；3)第二终端放弃在第二资源上接收数据，并且继续在第二资源上发送数据。另外可选的，当第二终端接收冲突指示信息，并且冲突指示信息还指示资源冲突类型为第四终端(第二终端的接收终端)存在收发并存时，第二终端可以有以下几种操作：1)第二终端重选第二资源，且重选的资源必须与第二资源位于不同的时间单元中；2)第二终端放弃在第二资源上发送侧行信息。
在本申请的实施例的情形a中，第二终端接收冲突指示信息，可选地，当冲突指示信息还指示资源冲突类型为第三终端(第二终端的接收终端)存在收发并存时，第二终端可以重传在第一资源上的数据。
可选地，在本申请的实施例的情形a中，当第一终端确定资源冲突类型为第二终端自身存在收发并存时，第一终端可以选择向第三终端发送冲突指示信息，第三终端收到该冲突指示信息后，可以重传在第四资源上的数据。

所属领域的技术人员可以清楚地了解到，为描述的方便和简洁，上述描述的系统、装置和单元的具体工作过程，可以参考前述方法实施例中的对应过程，在此不再赘述。
在本申请所提供的几个实施例中，应该理解到，所揭露的系统、装置和方法，可以通过其它的方式实现。例如，以上所描述的装置实施例仅仅是示意性的，例如，所述单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另一点，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，装置或单元的间接耦合或通信连接，可以是电性，机械或其它的形式。
