需要说明的是，本申请中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本申请中，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“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的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“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-b，a-c，b-c，或a-b-c，其中a，b，c可以是单个，也可以是多个.
终端设备在侧行链路(side link，SL)中可以有两种资源分配模式，一种是模式1：网络设备对终端设备进行资源分配，另一种是模式2：终端设备自主选择资源。当终端设备自主选择资源时，需要对资源进行监听SCI传输以识别可用资源，然后在可用资源中选择资源进行数据传输。
一种可能的实现方式中，如图1所示，终端设备使用感知(full sensing)的资源选择方式自主选择资源，包括以下步骤：
S101：终端设备确定资源选择窗口和候选资源集合。
如图2所示，终端设备在时刻n被触发进行资源选择。终端设备在资源池中确定资源选择窗口[n+T 1,n+T 2]，其中，T 1的取值满足
Figure PCTCN2020121703-appb-000001
其中，
Figure PCTCN2020121703-appb-000002
单位是时隙，
Figure PCTCN2020121703-appb-000003
的取值与SL BWP的子载波间隔来决定。
可能的理解方式中，
Figure PCTCN2020121703-appb-000004
可以理解为终端设备处理感知结果的时间。其中，T 2min的取值与侧行链路的优先级相关，侧行链路中优先级取值数值越小代表优先级级别越高。其中，在T 2min小于剩余包时延预算(packet delay budget,PDB)的情况下，T 2min≤T 2≤剩余PDB，否则T 2min等于剩余PDB。T 2min的单位是时隙，例如，T 2min取值可以为1，5，10，20个时隙。
在资源选择窗口[n+T 1,n+T 2]内存在多个候选时隙，一个单个时隙的候选资源记为R xy，R xy为时隙
Figure PCTCN2020121703-appb-000005
下的连续的L subCH个子信道的集合。其中，子信道的索引分别为x+j,j＝0,...,L subCH-1。
如图3所示，假设资源池中时隙
Figure PCTCN2020121703-appb-000006
对应的子信道个数为6，若L subCH＝2，则一个 单个时隙的候选资源为5个，其中，每个资源包括2个连续的子信道。
终端设备根据资源选择窗口[n+T 1,n+T 2]中单个候选时隙的个数及对应的单个时隙的候选资源，得到候选资源集合M total。
S102：终端设备确定感知窗口。
其中，感知的资源选择方式中的监听位置可以为感知窗口内配置用于监听的时域资源。其中，时域资源可以是时隙、符号或其他的时间单元，这里不作限定。
示例性的，终端设备可以将感知窗口确定为
Figure PCTCN2020121703-appb-000007
其中T 0是由网络设备使用无线资源控制(radio resource control，RRC)配置的，
Figure PCTCN2020121703-appb-000008
可以根据SL BWP的子载波间隔来确定的，如表1所示，不同的SL BWP的子载波间隔下
Figure PCTCN2020121703-appb-000009
的取值不同。
表1
Figure PCTCN2020121703-appb-000010
S103：确定参数Th(p i)。其中，Th(p i)是根据SL-ThresRSRP_pi_pj确定的，其中，SL-ThresRSRP_pi_pj是由网络设备使用RRC配置的，p j等于prio TX的值，p i是某一个优先级值。
S104：终端设备将S A初始化为候选资源集合。
可能的理解方式中，将S A初始化后，S A为上述候选资源集合M total。
S105：终端设备将没有监听的时域资源进行排除。
可能的实现方式中，终端设备将没有监听的时域资源对应的资源从S A中进行排除。
S106：终端设备根据监听的结果，判断进行监听的时域资源对应的资源是否进行排除。
可能的实现方式中，终端设备对感知窗口
Figure PCTCN2020121703-appb-000011
内的时域资源进行监听后，能够获取侧行控制信息(sidelink control information，SCI)的时域资源指示信息和参考信号接收功率(reference signal receiving power，RSRP)的测量值。通过判断SCI指示的时频资源和候选资源是否有重叠，以及比较RSRP的测量值和RSRP阈值的关系，可以判断是否将该SCI指示的时频资源从S A中进行排除。其中，RSRP阈值可以由网络设备使用RRC配置的。
可能的理解方式中，此时S A为将S105中在候选资源集合中将没有监听的时隙对应的资源排除后剩余的资源。
S107：终端设备确定S A中的资源在候选资源集合M total中所占的比例。
如果该比例超过了设定的阈值，则将RSRP阈值增加3dB，重新执行上述S104。
另一种可能的实现方式中，如图4所示，终端设备使用部分感知(partial sensing)的资源选择方式自主选择资源，包括以下步骤：
S401：终端设备确定资源选择窗口和候选资源集合。
在确定资源选择窗口阶段，终端设备在时刻n被触发进行资源选择，终端设备确 定资源选择窗口[n+T 1,n+T 2]，其中，T 1≤4，T 2min(prio TX)≤T 2≤100其中，其中T 2min(prio TX)是网络设备使用RRC配置的，如果RRC没有配置，则20≤T 2≤100，T 2的选择应该要满足时延要求。
在资源选择窗口[n+T 1,n+T 2]内存在Y个候选时隙，一个单个时隙的候选资源记为R xy，R xy为时隙
Figure PCTCN2020121703-appb-000012
下的连续的L subCH个子信道的集合。其中，子信道的索引分别为x+j,j＝0,...,L subCH-1，Y大于或等于网络设备使用RRC配置的下限。
如图3所示，假设资源池中时隙
Figure PCTCN2020121703-appb-000013
对应的子信道个数为6，若L subCH＝2，则一个单个时隙的候选资源为5个，其中，每个资源包括2个连续的子信道。
终端设备根据资源选择窗口[n+T 1,n+T 2]中候选时隙的个数及对应的单个时隙的候选资源，得到候选资源集合M total。
S403：终端设备确定监听的位置。
可能的实现方式中，终端设备根据资源选择窗口内的候选时隙集合和资源池上配置的周期确定部分感知中监听的位置。
部分感知的资源选择方式中的监听位置可以为配置用于监听的时域资源。其中，时域资源可以是时隙、符号或其他的时间单元，这里不作限定。
可能的实现方式中，终端设备确定的监听位置可以根据网络设备使用RRC配置的bitmap确定监听的位置。
示例性的，在资源选择窗口[n+T 1,n+T 2]内存在Y个候选时隙，如果时隙
Figure PCTCN2020121703-appb-000014
属于Y个候选时隙，终端设备根据网络设备使用RRC配置的bitmap确定监听的时隙
Figure PCTCN2020121703-appb-000015
其中k是bitmap中的第K个比特。终端设备完成监听后得到物理旁路控制信道(physical sidelink control channel，PSCCH)解码和RSRP测量结果。
S404：网络设备确定参数Th a,b。
其中，参数Th a,b的取值可以是网络设备使用RRC配置的。
S405：终端设备将S A初始化为候选资源集合，S B初始化为空集。
可能的理解方式中，将S A初始化后，S A为上述候选资源集合M total。
S406：终端设备根据监听结果，在S A中排除相应的资源。
可能的实现方式中，终端设备监听S403中确定监听的时域资源集合。当终端设备完成监听后，能够获取SCI的时域资源指示信息和RSRP的测量值。通过比较RSRP的测量值和RSRP阈值的关系，判断是否将该时隙在候选资源集合中对应的资源从S A中进行排除。其中，RSRP阈值可以是网络设备使用RRC配置的。
当在侧行链路中终端设备被配置了DRX模式时，请参见图5，为本申请实施例提供的一种DRX周期的示例图。如图5所示，一个完整的DRX周期500由DRX激活时间501和DRX非激活时间502构成。
可能的实现方式中，DRX周期内处于激活时间和非激活时间的时长可以是RRC根据终端设备的节能需求来配置的。例如，一个DRX周期内可能处于非激活时间的时长较长，处于激活时间的时长较短。
DRX功能通过控制终端设备在激活时间内监听PSCCH，在非激活时间内不监听PSCCH，达到降低终端设备的功耗的目的。
然而当终端设备被配置了DRX模式，并且使用感知或部分感知的资源选择方式进行资源选择的时候，终端设备需要监听的位置，和DRX周期里的激活时间或非激活时间可能会出现重叠，但侧行链路中引入DRX模式后终端设备的行为没有被定义，因此 无法确定是否在重叠的时间单元监听SCI传输。
基于上述问题，本申请实施例提供一种资源选择方法，终端设备被配置为感知或部分感知的资源选择方式，同时终端设备处于非连续接收DRX模式，且DRX模式中非激活时间与感知或部分感知的资源选择方式中的监听位置存在重叠的情况下，终端设备可以确定在重叠的时间单元监听，或者终端设备在重叠的时间单元不监听。这样，基于本申请实施例提供的方法，终端设备可以确定在重叠的时间单元确定对应的监听行为，从而可以在DRX模式中定义终端设备的行为。
本申请实施例的方法可以应用于各种通信系统，例如：第5代(5th generation，5G)通信系统，长期演进(long term evolution，LTE)通信系统，通用移动通信系统(universal mobile telecommunications system，UMTS)陆地无线接入网(UMTS terrestrial radio access network，UTRAN)系统，或者全球移动通信系统(global system for mobile communication，GSM)/增强型数据速率GSM演进(enhanced data rate for GSM evolution，EDGE)系统的无线接入网(GSM EDGE radio access network，GERAN)架构。通信系统还可以为例如公共陆地移动网络(public land mobile network，PLMN)系统、6G系统以及之后的通信系统等，对此，本申请对此不作限定。
图6给出了本申请实施例应用的一种通信系统600的示意图。在图6的应用场景中，通信系统600可以包括网络设备601以及终端设备602、终端设备603和终端设备604，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6仅以系统包括3个终端设备为例进行说明，但本申请实施例并不限于此，例如，通信系统600还可以包括更多的终端设备；类似地，通信系统也可以包括更多的网络设备，本申请实施例对此并不限定。
图6所示的应用场景中，终端设备之间可以进行D2D通信，终端设备与终端设备之间的通信链路可以称为侧行链路。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。D2D链路和V2X链路可以采用不同的接口进行通信。
如图6所示，D2D通信可以分为有网络覆盖、部分网络覆盖和没有网络覆盖3种。例如，图6中的终端设备602在网络设备601的覆盖范围内，可以接收网络设备601的信号，即终端设备602有网络覆盖，可以称为网络覆盖内终端设备；终端设备603不在网络设备601的覆盖范围内，但终端设备603可以接收网络覆盖内的终端设备602的信号，因此，终端设备603为部分网络覆盖，可以称为部分网络覆盖终端设备；终端设备604不在网络设备601的覆盖范围内，且终端设备604也无法接收网络覆盖内的终端设备602的信号，此时，终端设备604没有网络覆盖，可以称为网络覆盖外终端设备。
应理解，在本申请实施例中，网络设备可以是位于网络侧与终端设备进行通信的设备，该网络设备可以是GSM或CDMA中的基站收发台(base transceiver station，BTS)，也可以是WCDMA系统中的节点B(NodeB，NB)，还可以是LTE系统中的演进型节点B(evolutional Node B，eNB或eNodeB)，路边站点单元(Road Site Unit，RSU)，还可以是未来5G网络中的下一代节点B(next generation Node B，gNB)，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，或者该网络设备 可以为中继站、接入点以及未来5G网络中的网络设备或者未来演进的公共陆地移动网络(public land mobile network，PLMN)中的网络设备等。
应理解，在本申请实施例中，本申请涉及的终端设备可以为包含无线收发功能、且可以为用户提供通讯服务的设备。具体地，终端设备可以为V2X系统中的设备、D2D系统中的设备、MTC系统中的设备等。例如，可以指工业机器人、工业自动化设备、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，如图7所示，终端设备700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，还可以是有节能需求或者电池电量小的终端设备，还可以是行人，还可以是商业终端设备。终端设备在功能上要能够实现车对车(vehicle to vehicle，V2V)、车对行人(vehicle to pedestrain，V2P)、车与基础设施(vehicle to infrastucture，V2I)和车辆与网络(vehicle tonetwork，V2N)之间等业务的信息通讯，如图7所示，这些业务可以统称为V2X业务或侧行业务。因此，本申请实施例中的侧行业务可以包括以下业务中的一种或多种：V2V业务、V2I业务、V2P业务和P2P业务。
可能的实现方式中，终端设备700可以与网络保持连接，来获取配置信息。终端设备被触发资源选择，在选择资源进行数据传输之前需要监听资源，以识别可用资源和不可用资源，然后在可用资源中选择资源进行数据传输，与其他终端设备进行通信。
可选的，终端设备700也可以不与网络设备保持连接来，通过预先配置的方式获取配置信息。
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。
在图6或图7对应的应用场景中，终端设备可以执行本申请实施例的资源选择方法，在监听SCI传输后，其中，SCI传输包括第一级SCI和/或第二级SCI。根据监听的结果确定可用资源与其他终端设备进行通信，本申请实施例对具体的通信过程不作限定。
下面对本申请实施例中的一些词汇进行说明。其中，本申请实施例解释的词汇是为了便于本领域技术人员的理解，并不构成对于本申请实施例的限定。
本申请实施例描述的接收信号强度指示(received signal strength indication，RSSI)测量可以指在侧行链路中的一个时隙内，从第二个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号开始，被配置用于PSCCH和PSSCH的OFDM符号的总接收功率的线性平均。
本申请实施例描述的在时刻n测量的信道忙碌比(channel busy rate，CBR)可以是一个资源池中的一个CBR测量窗[n-a,n-1]内，子信道的SL RSSI测量值超过预配置或配置的临界值的比例。其中，a为高层参数配置的，a对应的值100slots或100ms。其中，高层参数的取值是网络设备使用RRC配置的，时隙索引为物理时隙索引。
可能的理解方式中，资源池可以为用于侧行传输的一个资源集合。
示例性的，如图8所示，假设CBR测量窗口内，子信道的个数为30个，从图8可以得到被占用的子信道个数为7个，则CBR为7/30。其中，SL-RSSI测量值高于预配置或配置的临界值的子信道被认为是被占用的子信道。
本申请实施例描述的SCI可以包括两级SCI，分别为第一级SCI和/或第二级SCI。其中，第一级SCI承载在PSCCH中，第二级SCI承载在PSSCH中。
本申请实施例描述的在时刻n测量的信道占用比率(channel occupancy ratio，CR)可以为在侧行链路中，时隙[n-a,n-1]中用于终端设备自身传输的子信道的个数和在时隙[n,n+b]中声称要用的子信道的个数的总数，比上资源池在时隙[n-a,n+b]中配置的子信道的总数。其中，a是一个正整数，b为0或正整数，a+b+1＝1000slots或1000slots(高层参数配置)，b<(a+b+1)/2，并且n+b不应该超过当前传输声称的最后一个传输机会。
可能的理解方式中，时隙[n-a,n-1]为历史时隙，终端设备可以得到在历史时隙[n-a,n-1]中的信道占用情况。在侧行链路中，声称的资源，是在时隙[n-a,n-1]发送的SCI中指示的在时隙[n,n+b]中的预留资源。
下面采用具体的实施例对本申请的资源选择方法进行详细说明，需要说明的是，下面几个具体实施例可以相互结合，对于相同或相似的内容，在不同的实施例中不再进行重复说明。
图9为本申请实施例提供的一种资源选择方法，包括下列步骤：
S901：终端设备被配置为感知或部分感知的资源选择方式。
S902：在终端设备处于非连续接收DRX模式，且DRX模式中非激活时间与感知或部分感知的资源选择方式中的监听位置存在重叠的情况下，终端设备在重叠的时间单元监听，或者终端设备在重叠的时间单元不监听。
具体的，终端设备处于DRX模式，可以理解为终端设备配置自身处于DRX模式，或者终端设备接收网络设备或其他终端设备的配置处于DRX模式。
本申请实施例中，终端设备被配置为部分感知的资源选择方式后，终端设备在一定时刻触发资源选择，终端设备确定资源选择窗口和部分感知窗口。其中，部分感知窗口可以理解为一个或多个监听时间单元，这里的时间单元可以是时隙，符号，部分符号，子时隙或子帧，这里不限定。部分感知窗口也可以理解为非连续的时隙集合，或者包含非连续时隙和连续时隙的集合，或者包括连续时隙的集合。
可选的，当终端设备被配置为感知的资源选择方式时，感知的资源选择方式中的 监听位置可以为感知窗口内配置用于监听的时域资源。

在图9对应的实施例的基础上，一种可能的实现方式中，S902包括：终端设备根据预先设置的方式在重叠的时间单元监听。
本申请实施例中，预先设置的方式可以理解为终端设备的执行条件，或者理解为终端执行的规则。其中，执行条件可以包括下述的一种或多种：终端设备测量的信道忙碌比CBR大于第一阈值；终端设备的侧行链路对应的优先级值小于第二阈值；在重叠的时间单元在感知或部分感知的资源选择方式的监听位置中所占的比例大于第三阈值；在DRX模式中激活状态激活时间与感知或部分感知的资源选择方式中的监听位置的重叠位置重叠的时间单元，在感知或部分感知的资源选择方式的监听位置中所占的比例小于第四阈值。
可选的，CBR为监听时隙的CBR测量值或者预配置的CBR测量值。
可选的，CBR为监听时隙前k个时隙的CBR测量值，即监听时隙为时隙n，则使用的CBR测量值为n-k时隙的CBR测量值，其中k为CBR处理时间。

可能的实现方式中，终端设备可以根据网络设备使用RRC配置的bitmap的指示来确定需要监听的位置。当DRX模式中非激活时间与bitmap指示监听的位置存在重叠的情况下，终端设备根据预先设置的方式在重叠的时间单元监听。
可选的，如图17所示，终端设备根据资源选择窗口中的时隙以及在资源池上配置的周期，确定部分感知的资源选择方式中的监听位置。然后终端设备根据网络设备使用RRC配置的bitmap确定bitmap指示为1的位置需要监听，bitmap指示为0的位置 不需要监听。此时，感知或部分感知的资源选择方式与DRX模式发生冲突，因此，终端设备根据预先设置的方式在重叠的时间单元监听。
可能的实现方式中，在终端设备测量的信道忙碌比CBR大于第一阈值的情况下，终端设备在重叠的时间单元监听。其中，终端设备在重叠(完全重叠或部分重叠)的时间单元监听的具体实施方式，可以对照前述实施例中介绍的方法，本申请实施例不再赘述。

可能的实现方式中，终端设备对重叠的时间单元是否监听的判断，是对重叠的时间单元中的全部时间单元统一进行判断。可选的，根据重叠的时间单元的起始时间单元相应的CBR测量值来判断是否监听该时间单元。
可能的理解方式中，当CBR大于第一阈值时，可以推断信道比较拥塞，终端设备如果没有监听指示要监听的位置，无法获取SCI信息、RSRP和/或RSSI测量结果，相应的资源无法保证是否为低干扰资源，如果没有排除监听指示要监听的位置对应的资源，会导致出现资源冲突的概率增加，从而降低数据传输的可靠性，增加了数据重传的次数。
可能的实现方式中，在终端设备的侧行链路对应的优先级值小于第二阈值的情况下，终端设备在重叠的时间单元进行资源监听。其中，终端设备在重叠(完全重叠或部分重叠)的时间单元监听的具体实施方式，可以对照前述实施例中介绍的方法，本申请实施例不再赘述。

可能的理解方式中，在侧行链路中，优先级值越小，代表优先级级别越高。如果终端设备的侧行链路对应的优先级值小于第二阈值，则可以推断指示要监听的位置对应的资源用于传输的数据的优先级较高，如果没有对指示要监听的位置进行监听，则不能保证数据传输的可靠性。
可能的实现方式中，在重叠的时间单元在感知或部分感知的资源选择方式的监听位置中所占的比例大于第三阈值的情况下，终端设备在重叠的时间单元监听。
可能的理解方式中，监听位置可以为bitmap指示监听的位置，或者为部分感知的资源选择方式中需要监听的位置，或者是部分感知的资源选择方式中的监听时隙集合。对应地，该重叠的时间单元为bitmap指示监听的位置与DRX模式中非激活时间重叠的时间单元。在重叠的时间单元在感知或部分感知的资源选择方式的监听位置中所占的比例大于第三阈值的情况下，可以推断指示监听位置中的小部分被进行监听，无法保证根据该一小部分的监听结果进行排除的资源是低干扰资源，因此终端设备在重叠 的时间单元监听。

可能的实现方式中，在DRX模式中激活时间与感知或部分感知的资源选择方式中的监听位置的重叠的时间单元，在感知或部分感知的资源选择方式的监听位置中所占的比例小于第四阈值的情况下，终端设备选择相应的位置监听SCI传输，从而使在DRX模式中激活时间与感知或部分感知的资源选择方式中的监听位置的重叠的时间单元，在感知或部分感知的资源选择方式的监听位置中所占的比例达到第四阈值。其中，具体监听的位置由终端设备来确定。

在图10对应的实施例的基础上，一种可能的实现方式中，S902包括：在DRX模式的非激活时间内，终端设备不监听SCI传输。
可能的实现方式中，在终端设备处于DRX模式，且DRX模式中非激活时间与感知或部分感知的资源选择方式中的监听位置存在重叠的情况下，终端设备重叠的时间单元不监听SCI传输。可以理解为，终端设备不在重叠的时间单元监听SCI传输。可以理解为终端设备遵循DRX模式的规则。
示例性的，在终端设备处于非连续接收DRX模式时，感知或部分感知的资源选择方式中的监听位置与DRX模式中非激活时间完全重叠，在这种情况下，重叠的时间单元为图11中110。在重叠的时间单元110处不监听SCI传输。
示例性的，在终端设备处于非连续接收DRX模式时，感知或部分感知的资源选择方式中的监听位置与DRX模式中非激活时间部分重叠，在这种情况下，重叠的时间单元为图11中111。在重叠的时间单元111处不监听SCI传输或接收信息。
可能的实现方式中，当DRX模式中非激活时间与感知或部分感知的资源选择方式中的监听位置完全重叠时，终端设备在重叠的时间单元不监听SCI传输。其中，DRX模式的配置和感知或部分感知的资源选择方式的配置是独立的。
示例性的，如图11所示，感知或部分感知的资源选择方式中的监听位置(时隙6)与DRX模式中非激活时间完全重叠，重叠的时间单元为图11中110。终端设备按照DRX的规则，在重叠的时间单元110不监听SCI传输。其中，该实例中重叠的时间单元为单个时隙。在重叠的时间单元为时隙的集合的情况下，具体的实施方式与重叠的时间单元为单个时隙相似，此处不再举例。
为了使终端设备可以在重叠的时间单元监听SCI传输，网络设备使用RRC配置感知或部分感知的监听时隙集合在DRX模式中的激活时间中。可能的实现方式中，通过配置感知或部分感知的监听时隙的偏移值和/或DRX开始时刻的偏移值来使得感知或部分感知的监听时隙集合在DRX的激活时间，或者感知或部分感知的监听时隙集合与DRX的激活时间最大限度的重叠。
可能的实现方式中，当DRX模式中非激活时间与感知或部分感知的资源选择方式中的监听位置部分重叠时，感知或部分感知的资源选择方式中的监听位置对应的时隙中，部分符号处于激活时间，部分符号处于非激活时间。在这种情况下，终端设备只监听处于激活时间的符号或只接收处于激活时间的符号中的信息。。
其中，本申请实施例可以使用PSCCH DMRS和/或PSSCH DMRS进行RSRP测量，SCI包括第一级SCI和第二级SCI，第一级SCI承载在PSCCH中，第二级SCI承载在 PSSCH中。因此要获取SCI和RSRP测量结果，需接收对应的PSCCH、PSCCH DMRS和/或PSSCH和/或PSSCH DMRS。
在侧行链路中，PSCCH占用的符号个数可以是网络设备使用RRC配置在资源池上的，其中，PSCCH占用的符号可以是2个或3个。在侧行链路中，一个时隙的第一个符号用于AGC，从第2个符号开始发送PSCCH和/或PSSCH。下面以不考虑AGC和GP，一个时隙中的符号均用于侧行传输为例，当一个时隙中的1个符号处于激活时间时，该符号用于AGC，因此终端设备对该符号进行监听后无法接收PSCCH。当一个时隙中的前2个符号处于激活时间时，此时该2个符号中第一个符号用于AGC，第二个符号用于发送PSCCH，但由于PSCCH占用的符号是2个，因此终端设备对这2个符号进行监听后，只能接收部分的PSCCH和部分的PSCCH DMRS，因此无法得到PSCCH。同理，当一个时隙中的前3个符号处于激活时间时，终端设备可以接收PSCCH，得到第一级SCI和PSCCH DMRS。在一个时隙中的符号均用于侧行传输时，在该时隙中除去AGC符合和GP符号之外的12个符号在激活时间的情况下，才可以保证能收到PSSCH和PSSCH DMRS。否则，当一个时隙中除去AGC符合和GP符号之外处于激活时间的符号的个数小于12时，都是可能收到第二级SCI和/或PSCCH DMRS。
示例性的，如图11所示，感知或部分感知的资源选择方式中的监听位置(时隙5)与DRX模式中非激活时间部分重叠，重叠的时间单元为图11中111。如图18所示，时隙2中有14个符号，其中5个符号处于激活时间，9个符号处于非激活时间。终端设备对处于激活时间的5个符号进行监听。其中，符号0用于AGC，符号1和符号2用于发送PSCCH，符号3至符号12用于发送PSSCH。因此终端设备可以获知PSCCH、PSCCH DMRS以及PSSCH和PSSCH DMRS的部分符号。基于获取的PSCCH和PSSCH，可以进行RSSI测量，即计算从时隙2中被配置用于PSCCH和PSSCH的OFDM符号的总接收功率的线性平均，其中，用于PSCCH和PSSCH的OFDM符号为符号1至符号4。终端设备也可以根据符号1至符号4中PSSCH DMRS进行RSRP测量。
可能的实现方式中，终端设备根据PSCCH DMRS或PSSCH DMRS进行RSRP测量由网络设备使用RRC配置在资源池上。当终端设备处于DRX模式时，终端设备使用PSCCH DMRS进行RSRP测量。具体的，终端设备处于DRX模式，可以理解为终端设备配置自身处于DRX模式，或者终端设备接收网络设备或其他终端设备的配置处于DRX模式。
可能的是实现方式中，当终端设备处于DRX模式时，终端设备可以使用PSCCH DMRS进行RSRP测量。这样终端设备可以获取更多的信息来进行资源选择，获取更可靠的传输资源。
可能的是实现方式中，网络设备配置了使能资源池内的DRX功能，则配置使用PSCCH DMRS进行RSRP测量的方式。这样终端设备可以获取更多的信息来进行资源选择，获取更可靠的传输资源。
可能的实现方式中，当终端设备处于DRX模式时，终端设备只使用PSCCH DMRS进行RSRP测量，或者，根据PSCCH DMRS或PSSCH DMRS进行RSRP测量，这样可以保证终端设备在无法全部解码PSSCH的情况下仍然可以进行RSRP测量。这样，在资源选择的过程中获取更多的先验信息，提高了确定的资源的可靠性和可用性，进 而提高了数据传输的可靠性。
本申请实施例提供一种资源选择方法，DRX模式中非激活时间与感知或部分感知的资源选择方式中的监听位置存在重叠的时间单元的情况下，终端设备在重叠的时间单元不进行监听，提高了DRX模式下终端设备的节能效果。同时，在监听位置的部分符号和DRX模式下非激活时间重叠的时候，使用PSCCH DMRS进行RSRP测量，使得可以最大限度的获知RSRP测量结果，从而可以排除高干扰的资源。这样，在资源选择的过程中获取更多的先验信息，提高了确定的资源的可靠性和可用性，进而提高了数据传输的可靠性。
在上述终端设备对重叠的时间单元不进行监听的实施例的基础上，一种可能的实现方式中，还包括：终端设备将重叠的时间单元对应的资源从第一候选资源集合或第二候选资源集合中排除，得到剩余资源。
可能的实现方式中，终端设备将重叠的时间单元对应的资源从第一候选资源集合或第二候选资源集合中排除，得到第三候选资源集合，在第三候选资源集合小于全部候选资源的第五比例的情况下，剩余资源为第一候选资源集合或第二候选资源集合。即，在第三候选资源集合小于全部候选资源的第五比例的情况下，将排除的重叠的时间单元对应的资源恢复至第一候选资源或第二候选资源集合中。
可能的理解方式中，当剩余资源在全部候选资源集合中的占比较低时，可以判断可用于数据传输的资源较少，为保证数据传输的可靠性，将排除的资源恢复至候选资源集合中。
可能的实现方式中，终端设备进行资源排除时，如图19所示，可以包括下述步骤：
S1901：终端设备将没有监听的时间单元相应的资源从全部候选资源集合中进行排除。
可能的实现方式中，在部分感知的资源选择方式中，终端设备将没有监听的时隙相应的资源从全部候选资源集合中进行排除，得到第一候选资源集合。
可能的理解方式中，没有监听的时间单元相应的资源为下述资源：假设在没有监听的时间单元中接收了一个虚拟SCI(虚拟SCI，实际并未接收)，该SCI指示的时频资源为没有监听的时间单元相应的资源。其中，该SCI指示的时频资源可以包括该时间单元下的全部子信道以及对应周期下的预留资源，该SCI指示的预留资源的周期可以是配置的周期集合中的一个，该周期集合可以由网络设备配置在资源池上。
其中，全部候选资源集合为资源选择窗口对应的候选资源集合，也可以理解为资源选择窗口中包含的候选资源集合。
该步骤S1901为可选执行步骤。
S1902：终端设备将监听时间单元相应的资源从第一候选资源集合中排除，得到第三候选资源集合。
其中，假设终端设备在执行S1902对应的资源排除步骤之前，未执行S1901，则该第一候选资源集合可以为全部候选资源集合。
可能的实现方式中，终端设备监听SCI传输，获取相应的RSRP测量结果，该SCI指示的时频资源和第一候选资源集合中的第一候选资源有重叠，且该SCI相应的RSRP 测量值大于预设阈值，则将该SCI指示的时频资源从第一候选资源集合中进行排除，得到第二候选资源集合。可能的理解方式中，当SCI相应的RSRP测量值大于预设阈值时，说明该资源为高干扰资源，因此将该SCI指示的时频资源从第一候选资源集合中排除。
S1903：终端设备将在DRX非激活时间的监听时间单元相应的资源，从第一候选资源集合或第三候选资源集合中排除，得到第二候选资源集合。其中，时间单元可以是时隙，符号，部分符号或子时隙等，这里不限定。
其中，监听时间单元可以理解为接收时间单元，也可以理解为感知时间单元，或者理解为测量时间单元。
其中，在DRX非激活时间的监听时间单元可以理解为在部分感知的资源选择方式中被配置监听的时间单元在DRX非激活时间，或者可以理解为在部分感知的资源选择方式中被配置监听的时间单元和DRX非激活时间有重叠。
可能的实现方式中，当部分感知的资源选择方式中被配置监听的时间单元和DRX非激活时间全部重叠时，即被配置监听的时间单元都不监听，即不执行上述S1902中的资源排除步骤。在这种情况下，S1903中的第三候选资源集合可以为第一候选资源集合。
在DRX非激活时间的监听时间单元相应的资源为下述第四资源集合：
假设在DRX非激活时间的监听时间单元没有监听SCI，但假设在该时间单元接收了一个虚拟SCI，该SCI指示的时频资源为DRX非激活时间的监听时间单元相应的资源。其中，该SCI指示的时频资源可以包括该时间单元下的全部子信道以及对应周期下的预留资源，该SCI指示的预留资源的周期可以是配置的周期集合中的一个，该周期集合可以由网络设备配置在资源池上。
示例性的，在DRX非激活时间的监听时间单元中满足前述CBR和/或优先级值和/或周期中至少一个条件的监听时间单元相应的资源为第五资源集合。
示例性的，以下以时间单元为时隙来进行描述。
可选的，终端设备可以先执行S1902再执行S1903或者终端设备可以先执行S1903再执行S1902。或者当执行S1901时，S1901可以包括S1903，终端设备可以先执行S1901和S1903再执行S1902，或者终端设备先执行S1901和S1902，再执行S1903，最后得到剩余资源。
终端设备通过资源排除确定候选资源集合N，其中，候选资源集合N为终端设备进行资源排除后得到的剩余资源，并且该候选资源集合N为最终上报给高层的资源。
其中，终端设备确定候选资源集合N的一种可能实现为：
终端设备将DRX非激活时间的监听时隙相应的资源，从第一候选资源集合或第三候选资源集合中进行排除，得到第二候选资源集合。在第二选资源集合小于全部候选资源的第五比例的情况下，将RSRP阈值增加3dB，重复执行上述将DRX非激活时间的监听时隙相应的资源从第一候选资源集合中或第三候选资源集合进行排除的步骤(S1903)。若RSRP阈值增加3dB的次数为至少一次或者大于一个次数阈值，或者将RSRP阈值的增加后达到一个上限阈值，则终端设备不将DRX非激活时间的监听时隙相应的资源，从第一候选资源集合或第三候选资源集合中进行排除。在这种情况下， 剩余资源为第一候选资源或第三候选资源集合。
此时可以理解为，终端设备优先选择第二候选资源集合。在第二候选资源集合不满足上述条件时，选择第三候选资源集合，即选择第四候选资源集合为候选资源。可以理解的是，第三候选资源集合比第四候选资源集合优先级更高，被选择的概率更高。这样可以保证终端设备优先使用干扰更低更可靠的资源。其中，终端设备确定候选资源集合N的另一种可能实现为：终端设备将DRX非激活时间的监听时隙相应的资源，从第一候选资源集合或第三候选资源集合中进行排除，得到第二候选资源。在第二候选资源集合大于或等于全部候选资源集合的第五比例的情况下，终端设备将DRX非激活时间的监听时隙相应的资源，从第一候选资源集合或第三候选资源集合中进行排除，即不执行上述将RSRP阈值增加3dB的步骤。在这种情况下，剩余资源为第二候选资源集合。
其中，第五比例可以是网络设备使用RRC配置的。可选的，第五比例可以和感知或部分感知的资源选择方式相关联，或者第五比例可以和DRX模式相关联，或者第五比例和节能模式相关联，处于节能模式的终端设备使用第五比例。
可能的实现方式中，在DRX模式中非激活时间与感知或部分感知的资源选择方式中的监听位置完全重叠时，终端设备重叠的时间单元不监听，按照配置的周期将重叠的时间单元相应的资源在候选资源集合中进行排除，得到剩余资源。其中，全部候选资源集合为资源选择窗[n+T 1,n+T 2]内的资源。其中，周期为配置在资源池的周期集合的子集或全集。可选的，所述周期可以是一个或多个周期，可选的，所述周期可以是终端设备传输周期性数据的周期或者是传输非周期性数据的周期，可选的，配置的周期为网络设备配置在资源池的周期集合。
示例性的，如图11所示，终端设备在感知或部分感知的资源选择方式中的监听位置为时隙4、时隙5和时隙6，其中，时隙6与DRX模式下的非激活时间完全重叠。终端设备根据配置的周期将时隙6对应的资源从候选资源集合中排除，得到剩余资源。可能的理解方式中，剩余资源为时隙4和时隙5对应的资源。
可能的实现方式中，在DRX模式中非激活时间与感知或部分感知的资源选择方式中的监听位置部分重叠时，该重叠的时间单元对应的时隙中，部分符号处于激活时间，部分符号处于非激活时间。在这种情况下，终端设备只监听处于激活时间的符号，根据上述实施例的方法，通过PSCCH DMRS来进行RSRP测量，用于判断是否将重叠的时间单元相应的资源进行排除。其中，通过PSCCH DMRS来进行RSRP测量的具体实施方式可以对应上述实施例的记载，此处不再赘述。
示例性的，如图11所示，终端设备在感知或部分感知的资源选择方式中的监听位置为时隙4、时隙5和时隙6，其中，时隙5与DRX模式下的非激活时间部分重叠。若如图18所示，时隙5中5个符号处于激活时间，9个符号处于非激活时间。终端设备对处于激活时间的5个符号进行监听，得到PSCCH DMRS来进行RSRP测量，判断时隙5对应的资源是否在候选资源集合中进行排除。
本申请实施例提供一种资源选择方法，终端设备在重叠的时间单元不进行监听，直接将重叠的时间单元对应的资源从候选资源集合中排除，得到剩余资源，这样可以先在候选资源集合中排除相应的资源。若不将相应的资源进行排除，可能导致终端设 备选择用于数据传输的资源为高干扰的资源。同时，终端设备将重叠的时间单元对应的资源从候选资源集合中进行排除后，通过判断剩余资源在候选资源集合中的占比，确定是否将排除的资源恢复至候选资源集合中。当剩余资源在候选资源结合中占比较小时，可以推断，终端设备可以选择用于数据传输的资源较少，无法保证数据传输的可靠性。
在上述终端设备对重叠的时间单元不进行监听的实施例的基础上，一种可能的实现方式中，在终端设备的信道忙碌比CBR大于第六阈值的情况下，终端设备将重叠的时间单元对应的资源从资源池中进行排除。
其中，第六阈值可以网络设备使用RRC配置在资源池上的。
可选的，CBR为监听时隙的CBR测量值或者预配置的CBR测量值。
可选的，CBR为监听时隙前k个时隙的CBR测量值，即监听时隙为时隙n，则使用的CBR测量值为n-k时隙的CBR测量值，其中k为CBR处理时间。可能的实现方式中，在DRX模式中非激活时间与感知或部分感知的资源选择方式中的监听位置完全重叠时，且终端设备的信道忙碌比CBR大于第六阈值的情况下，按照配置的周期将重叠的时间单元相应的资源在第一候选资源集合中进行排除，得到剩余资源。
可选的，当与DRX非激活时间完全重叠的时间单元为多个时隙集合时，在终端设备的信道忙碌比CBR大于第六阈值的情况下，按照配置的周期将重叠的时间单元相应的资源在第一候选资源集合中进行排除，得到剩余资源。在这种情况下，CBR为监听时隙前k个时隙的CBR测量值，即监听时隙为时隙n，则使用的CBR测量值为n-k时隙的CBR测量值，其中k为CBR处理时间。示例性的，如图12所示，在终端设备处于非连续接收DRX模式时，感知或部分感知的资源选择方式中的监听位置(时隙4、时隙5和时隙6)与DRX模式中非激活时间完全重叠，在这种情况下，将时隙4、时隙5和时隙6当作一个整体来看，与DRX非激活时间完全重叠的时间单元为图12中120、121和122。其中，重叠的时间单元为时隙的集合。在这种情况下，CBR为监听时隙前3个时隙(时隙4、时隙5和时隙6)的CBR测量值。
可选的，当与DRX非激活时间完全重叠的时间单元为单个时隙时，在终端设备的信道忙碌比CBR大于第六阈值的情况下，按照配置的周期将重叠的时间单元相应的资源在第一候选资源集合中进行排除，得到剩余资源。在这种情况下，CBR为监听时隙的CBR测量值或者预配置的CBR测量值。
示例性的，如图11所示，在终端设备处于非连续接收DRX模式时，感知或部分感知的资源选择方式中的监听位置中的一个时隙(时隙6)可以与DRX模式中非激活时间完全重叠，在这种情况下，与DRX非激活时间完全重叠的时间单元为图11中110。其中，重叠的时间单元为单个时隙。在这种情况下，对应的CBR取值为时隙6的CBR测量值或与预配置的CBR测量值。可能的实现方式中，在DRX模式中非激活时间与感知或部分感知的资源选择方式中的监听位置部分重叠时，且终端设备的信道忙碌比CBR大于第六阈值的情况下，该重叠的时间单元对应的时隙中，部分符号处于激活时间，部分符号处于非激活时间，终端设备只监听处于激活时间的符号，根据上述实施例的方法，通过PSCCH DMRS来进行RSRP测量，用于判断是否将重叠的时间单元相应的资源进行排除。其中，通过PSCCH DMRS来进行RSRP测量的具体实施方式可以 对应前述实施例的记载，此处不再赘述。
本申请实施例提供一种资源选择方法，终端设备对重叠的时间单元不监听SCI传输，在终端设备的信道忙碌比CBR大于第六阈值的情况下，终端设备将重叠的时间单元相应的资源从资源池中进行排除。这样，在信道比较拥塞的时候，终端设备将重叠的时间单元对应的资源从资源池中直接进行排除，可以避免出现资源冲突。
在上述终端设备对重叠的时间单元不进行监听的实施例的基础上，另一种可能的实现方式中，在终端设备侧行链路相应的优先级值小于第七阈值的情况下，终端设备将重叠的时间单元对应的资源从第一候选资源集合中进行排除。
可选的，终端设备侧行链路相应的优先级值为重叠的时间单元相关联的部分感知资源选择的优先级值。比如，重叠的时间单元为第一时隙，第一时隙是用于第一优先级的部分感知的资源选择中的监听时隙。重叠的时间单元中的监听时隙可能对应一个优先级值或多个优先级值，当该监听时隙对应多个优先级值，则该监听时隙的优先级值为多个优先级值中的最小值。
可选的，在终端设备侧行链路相应的优先级值小于第七阈值的情况下，终端设备将重叠的时间单元对应的资源从第一候选资源集合中进行排除，包括根据重叠的时间单元中的至少一个时间单元相应的优先级值确定将所述至少一个时间单元相应资源从第一候选资源集合中进行排除。
示例性的，如图12所示，在终端设备处于非连续接收DRX模式时，感知或部分感知的资源选择方式中的监听位置(时隙4、时隙5和时隙6)与DRX模式中非激活时间完全重叠，在这种情况下，将时隙4、时隙5和时隙6当作一个整体来看，与DRX非激活时间完全重叠的时间单元为图12中120、121和122。其中，重叠的时间单元为时隙的集合。在这种情况下，假设时隙4是用于第四优先级的部分感知的资源选择中的监听时隙，时隙5是用于第五优先级的部分感知的资源选择中的监听时隙，时隙6是用于第六优先级的部分感知的资源选择中的监听时隙。此时，终端设备侧行链路相应的优先级值为时隙4、时隙5和时隙6分别对应的优先级中的最小值。若时隙4、时隙5和时隙6分别对应的优先级中的最小值为时隙6对应的第六优先级，则在第六优先级小于第七阈值的情况下，终端设备将重叠的时间单元(时隙4、时隙5和时隙6)相应的资源从第一候选资源集合中进行排除。
示例性的，如图11所示，在终端设备处于非连续接收DRX模式时，感知或部分感知的资源选择方式中的监听位置中的一个时隙(时隙6)可以与DRX模式中非激活时间完全重叠，在这种情况下，与DRX非激活时间完全重叠的时间单元为图11中110。其中，重叠的时间单元为单个时隙。假设，时隙6是用于第六优先级的部分感知的资源选择中的监听时隙。在第六优先级小于第七阈值的情况下，终端设备将重叠的时间单元对应的资源从第一候选资源集合中进行排除。
其中，第七阈值可以是网络设备使用RRC配置在资源池上的。
可能的理解方式中，在侧行链路中，优先级值越小，代表优先级越高。对于优先级高的侧行链路，应该选择低干扰的资源来进行数据传输。但在本申请实施例中，对重叠的时间单元不监听SCI传输，从而无法保证重叠的时间单元对应的资源是否为低干扰资源，因此为保证数据传输的可靠性，在终端设备侧行链路相应的优先级值小于 第七阈值的情况下，终端设备直接将重叠的时间单元对应的资源从第一候选资源集合中进行排除。
可能的实现方式中，在DRX模式中非激活时间与感知或部分感知的资源选择方式中的监听位置完全重叠时，且终端设备侧行链路相应的优先级值小于第七阈值的情况下，按照配置的周期将重叠位置重叠的时间单元相应的资源在第一候选资源中进行排除，得到剩余资源。
可能的实现方式中，在DRX模式中非激活时间与感知或部分感知的资源选择方式中的监听位置部分重叠时，且终端设备侧行链路相应的优先级值小于第七阈值的情况下，该重叠的时间单元对应的时隙中，部分符号处于激活时间，部分符号处于非激活时间，终端设备只监听处于激活时间的符号，根据前述实施例的方法，通过PSCCH DMRS来进行RSRP测量，用于判断是否将重叠的时间单元相应的资源进行排除。
可能的实现方式中，第一周期小于周期阈值，终端设备确定将重叠的时间单元对应的资源从第一候选资源集合中排除。第一周期为配置在资源池上的周期集合中的周期。当第一周期越小，预留资源的间隔越短，需要监听的时隙越多，相应的重叠的时间单元越多，此时排除重叠的时间单元对应的资源，可以保证终端设备的节能效果。其中，重叠的时间单元可以为单个时隙或时隙集合。
示例性的，如图12所示，如图12所示，在终端设备处于非连续接收DRX模式时，感知或部分感知的资源选择方式中的监听位置(时隙4、时隙5和时隙6)与DRX模式中非激活时间完全重叠，在这种情况下，将时隙4、时隙5和时隙6当作一个整体来看，与DRX非激活时间完全重叠的时间单元为图12中120、121和122。其中，重叠的时间单元为时隙的集合。在这种情况下，可以推断配置在资源池中的第一周期较小，导致重叠的时间单元较多，若配置的第一周期小于周期阈值，则排除重叠的时间单元(时隙4、时隙5和时隙6)对应的资源。
示例性的，如如图11所示，在终端设备处于非连续接收DRX模式时，感知或部分感知的资源选择方式中的监听位置中的一个时隙(时隙6)可以与DRX模式中非激活时间完全重叠，在这种情况下，与DRX非激活时间完全重叠的时间单元为图11中110。其中，重叠的时间单元为单个时隙。在这种情况下，若第一周期小于周期阈值，则排除重叠的时间单元(时隙4、时隙5和时隙6)对应的资源。
可能的实现方式中，终端设备处于DRX模式，使用部分感知的资源选择方式，在DRX模式中非激活时间与部分感知的资源选择方式中的监听位置有重叠时，由网络设备配置终端设备在重叠的时间单元监听或者不监听。配置信令可以是RRC信令或者主系统信息块(master information block，MIB)或者系统信息块(system information block，SIB)或者媒体接入控制的控制单元(medium access control control element，MAC CE)或者物理旁链路广播信道(physical sidelink block channel，PSBCH)。
本申请实施例提供一种资源选择方法，终端设备对重叠位置重叠的时间单元不监听SCI传输，在终端设备侧行链路相应的优先级值小于第七阈值的情况下，终端设备将重叠的时间单元对应的资源从资源池中进行排除。这样，在优先级较高的侧行链路中，在无法监听资源是否为低干扰的资源时，终端设备将重叠的时间单元对应的资源从资源池中直接进行排除，可以保证数据传输的可靠性。
在图19对应的实施例的基础上，本申请实施例提供一种资源选择方法，终端设备确定在前述第四资源集合中，将除第五资源集合以外的资源进行排除，得到第六资源集合。终端设备在第一候选资源集合或第三候选资源集合中将第六资源集合进行排除，得到剩余资源。
其中，第五资源集合为终端设备测量的信道忙碌比CBR小于或等于第六阈值，和/或优先级值大于或等于第七阈值，和/或第一周期大于或等于周期阈值时在DRX非激活时间的监听时间单元对应的资源。
可能的理解方式中，当终端设备测量的信道忙碌比CBR小于或等于第六阈值时，可以推断信道较空或者不拥塞，在这种情况下，终端可以不将相应的资源排除。这里可以理解为，相应的资源为可用资源。
可能的理解方式中，当侧行链路的优先级值大于或等于第七阈值时，对应的优先级级别较低，说明对应的资源用于传输的数据的优先级较低，在这种情况下，终端可以不将相应的资源排除。这里可以理解为，相应的资源为可用资源。
可能的理解方式中，当第一周期大于或等于周期阈值时，可以推断第一周期较大。当第一周期较大时，预留资源的间隔较长，需要监听的时隙较少，可以保证终端设备的节能效果。在这种情况下，终端可以不将相应的资源排除。这里可以理解为，相应的资源为可用资源。可能的理解方式中，第五资源集合的优先级高于第六资源集合。终端设备优先使用第五资源集合。
终端设备通过资源排除确定候选资源集合N，其中，候选资源集合N为终端设备进行资源排除后得到的剩余资源，并且该候选资源集合N为最终上报给高层的资源。
可能的实现方式中，在第一候选资源集合或第三候选资源集合中将第六候选资源集合进行排除，得到第七资源集合。
其中，在第七资源集合小于全部候选资源的第五比例的情况下，将RSRP阈值增加3dB，重复执行上述将第六候选资源集合从第一候选资源集合中进行排除的步骤。若RSRP阈值增加3dB的次数为至少一次或者大于一个次数阈值，或者将RSRP阈值的增加后达到一个上限阈值，则终端设备不将第六候选资源集合从第一候选资源集合或第三候选资源集合中进行排除。在这种情况下，剩余资源为第一候选资源或第三候选资源集合。
其中，在第七资源集合大于或等于全部候选资源的第五比例的情况下，在第七资源集合中将监听时间单元相应的资源从第七候选资源集合中进行排除，即执行图19中S1902的步骤，得到第八候选资源集合。
在第八候选资源集合小于全部候选资源的第五比例的情况下，将RSRP阈值增加3dB，重复执行上述将监听时间单元相应的资源从第七候选资源集合中进行排除的步骤。若RSRP阈值增加3dB的次数为至少一次或者大于一个次数阈值，或者将RSRP阈值的增加后达到一个上限阈值，则终端设备不将监听时间单元相应的资源从第七候选资源集合中进行排除。在这种情况下，剩余资源为第一候选资源集合中排除监听时间单元相应的资源后得到的资源，即不将第六候选资源集合进行排除。
可能的理解方式中，终端设备监听SCI传输，获取相应的RSRP测量结果，将该SCI指示的时频资源中和第七候选资源集合中有重叠的资源进行排除，得到第八候选 资源。可能的实现方式中，终端设备监听SCI传输，获取相应的RSRP测量结果，且该SCI相应的RSRP测量值大于预设阈值的情况下，则将监听的时隙相应的资源该SCI指示的时频资源从第七候选资源集合中进行排除，得到第八候选资源集合。可能的理解方式中，当SCI相应的RSRP测量值大于预设阈值时，说明该资源为高干扰资源，因此将监听的时隙对应的资源该SCI指示的时频资源从第七候选资源集合中排除。
其中，在第八资源集合大于或等于全部候选资源的第五比例的情况下，在第七资源集合中将监听时间单元相应的资源从进行排除，得到第八资源。在这种情况下，剩余资源为第一候选资源。此时可以理解为，终端设备优先选择第七候选资源集合。在第七候选资源集合不满足上述条件时，选择第八候选资源集合为候选资源。可以理解的是，第七候选资源集合比第八候选资源集合优先级更高，被选择的概率更高。这样可以保证终端设备优先使用干扰更低更可靠的资源。
一种实现方式中，终端设备将DRX非激活时间的监听时隙相应的资源，从第一候选资源集合或第三候选资源集合中进行排除，得到第二候选资源集合。在第二候选资源集合小于全部候选资源的第五比例的情况下，剩余资源为第一候选资源集合或第三候选资源集合。即不在第一候选资源集合或第三候选资源集合中排除DRX非激活时间的监听时隙相应的资源。即不在第一候选资源集合或第三候选资源集合中排除第四资源集合。即第四资源集合在第二候选资源集合小于全部候选资源的第五比例的情况下为可用资源。
示例性的，剩余资源为第一候选资源则执行步骤S1902。
一种实现方式中，终端设备从第一候选资源集合或第三候选资源集合中排除第六资源集合，得到第二候选资源集合。在第二候选资源集合小于全部候选资源的第五比例的情况下，剩余资源为第一候选资源集合或第三候选资源集合。即不在第一候选资源集合或第三候选资源集合中排除第六资源集合。即第六资源集合在第二候选资源集合小于全部候选资源的第五比例的情况下为可用资源。
一种实现方式中，终端设备从第一候选资源集合或第三候选资源集合中排除第六资源集合，得到第二候选资源集合。在第二候选资源集合小于全部候选资源的第五比例的情况下，剩余资源为第一候选资源集合或第三候选资源集合。进一步，终端设备从第一候选资源集合或第三候选资源集合中排除第四资源集合，判断剩余资源是否可以满足大于全部候选资源的第五比例的条件。
一种实现方式中，当在第三候选资源集合中排除第六资源集合或第六资源集合后，剩余资源满足大于全部候选资源的第五比例的条件，则该剩余资源为候选资源集合N。
一种实现方式中，第三候选资源集合为候选资源集合N。
一种实现方式中，终端设备从第一候选资源集合或第三候选资源集合中排除第六资源集合，得到第二候选资源集合。在第二候选资源集合大于全部候选资源的第五比例的情况下，剩余资源为第二候选资源集合。
一种实现方式中，终端设备从第一候选资源集合或第三候选资源集合中排除第六资源集合，得到第二候选资源集合。在第二候选资源集合小于全部候选资源的第五比例的情况下，将RSRP阈值增加3dB，重复执行上述将DRX非激活时间的监听时隙相应的资源从第一候选资源集合中或第三候选资源集合进行排除的步骤(S1903)。若RSRP 阈值增加3dB的次数为至少一次或者大于一个次数阈值，或者将RSRP阈值的增加后达到一个上限阈值，则终端设备不将第六资源，从第一候选资源集合或第三候选资源集合中进行排除。在这种情况下，剩余资源为第一候选资源或第三候选资源集合。
可以理解的是，在第四资源集合中，终端设备优先使用第五资源集合，即使用低干扰的或者优先级值大(优先级级别低)的资源。
