具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
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地说明本申请实施例的技术方案，并不构成对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。
请参考图1，其示出了本申请一个实施例提供的网络架构的示意图。该网络架构可以包括：核心网11、接入网12和终端设备13。
核心网11中包括若干核心网设备。核心网设备的功能主要是提供用户连接、对用户的管理以及对业务完成承载，作为承载网络提供到外部网络的接口。例如，5G(5th Generation，第五代移动通信技术)NR(New Radio，新空口)系统的核心网中可以包括AMF(Access and Mobility Management Function，接入和移动性管理功能)实体、UPF(User Plane Function，用户平面功能)实体和SMF(Session Management Function，会话管理功能)实体等设备。
接入网12中包括若干接入网设备14。5G NR系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。接入网设备14是一种部署在接入网12中用以为终端设备13提供无线通信功能的装置。接入网设备14可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备接入网设备功能的设备的名称可能会有所不同，例如在5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“接入网设备”这一名称可能会变化。为方便描述，本公开实施例中，上述为终端设备13提供无线通信功能的装置统称为接入网设备。
终端设备13的数量通常为多个，每一个接入网设备14所管理的小区内可以分布一个或多个终端设备13。终端设备13可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备、移动台(Mobile Station，MS)等等。为方便描述，上面提到的设备统称为终端设备。接入网设备14与核心网设备之间通过某种空中技术相互通信，例如5G NR系统中的NG接口。接入网设备14与终端设备13之间通过某种空中技术互相通信，例如Uu接口。
终端设备13和终端设备13(例如车载设备与其它设备(如其它车载设备、手机、RSU(Road Side Unit，路测单元)等))之间可以通过直连通信接口(如PC5接口)互相通信， 相应地，该基于直连通信接口建立的通信链路可以称为直连链路或SL。SL传输即为终端设备与终端设备之间通过侧行链路直接进行通信数据传输，不同于传统的蜂窝系统中通信数据通过接入网设备接收或者发送，SL传输具有时延短、开销小等特点，适合用于地理位置接近的两个终端设备(如车载设备和地理位置接近的其它周边设备)之间的通信。需要说明的是，在图1中，仅以V2X(vehicle to everything，车联网)场景下的车对车通信为示例，SL技术可以应用于各种终端设备之间直接进行通信的场景。或者说，本申请中的终端设备是指任意一种利用SL技术通信的设备。
本公开实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。本公开实施例描述的技术方案可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统。
在介绍本申请技术方案之前，先对本申请涉及的一些背景技术知识进行介绍说明。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
关于SL传输，3GPP定义了两种传输模式：模式A和模式B。
模式A：终端设备的传输资源是由接入网设备(如基站)分配的，终端设备根据接入网设备分配的传输资源在侧行链路上进行通信数据的传输，其中，接入网设备既可以为终端设备分配单次传输的传输资源，也可以为终端设备分配半静态传输的传输资源。
模式B：终端设备自行在资源池中选取传输资源进行通信数据的传输。具体地，终端设备可以通过侦听的方式在资源池中选取传输资源，或者通过随机选取的方式在资源池中选取传输资源。
接下来主要介绍NR V2X系统中SL通信，终端设备自主进行资源选择的方法(也即上述模式B)。
NR V2X系统中SL通信的物理层结构如图2所示。PSCCH(Physical Sidelink Control Channel，物理侧行控制信道)用于承载第一侧行控制信息，PSSCH(Physical Sidelink Shared Channel，物理侧行共享信道)用于承载数据和第二侧行控制信息。PSCCH和PSSCH在同一时隙中发送。上述第一侧行控制信息和第二侧行控制信息可以是两个具有不同作用的侧行控制信息。例如，第一侧行控制信息承载在PSCCH中，主要包含资源侦听相关的域，方便其他终端设备解码后进行资源排除与资源选择。在PSSCH中，除了数据外，还承载第二侧行控制信息，第二侧行控制信息主要包括数据解调相关的域，方便其他终端设备解调该PSSCH中的数据。
在NR V2X系统中，上述模式B下，终端设备自行选择传输资源来发送数据。资源预留则是资源选择的前提。
资源预留是指终端设备在PSCCH中发送第一侧行控制信息预留接下来要使用的资源。在NR V2X系统中，支持TB(Transport Block，传输块)内的资源预留也支持TB间的资源预留。
如图3所示，终端设备发送第一侧行控制信息，利用其中“Time resource assignment(时间资源分配)”和“Frequency resource assignment(频率资源分配)”域指示当前TB的N个时频资源(包括当前发送所用的资源)。其中N≤Nmax，在NR V2X中，Nmax等于2或3。同时，上述N个被指示的时频资源应分布在W个时隙内。在NR V2X中，W等于32。例如，图3所示的TB1中，终端设备在PSSCH发送初传数据的同时在PSCCH中发送第一侧行控制信息，利用上述两个域指示初传和重传1的时频资源位置(即此时N＝2)，即预留重传1的时频资源。并且，初传和重传1在时域上分布在32个时隙内。同理，在图3所示的TB1中，终端设备利用重传1的PSCCH中发送的第一侧行控制信息指示重传1和重传2的时频资源位置，重传1与重传2在时域上分布在32个时隙内。
同时，终端设备发送第一侧行控制信息时利用“Resource reservation period(资源预留周期)”域进行TB间的资源预留。例如图3中，终端设备在发送TB1的初传的第一侧行控制信息时，利用“Time resource assignment”和“Frequency resource assignment”域指示TB1初传和重传1的时频资源位置，记为{(t 1,f 1),(t 2,f 2)}。其中t 1、t 2代表TB1初传和重传1资源的时域位置，f 1、f 2代表相应的频域位置。如果该第一侧行控制信息中，“Resource reservation period”域的取值为100毫秒，则该SCI(Sidelink Control Information，侧行链路控制信息)同时指示了时频资源{(t 1+100,f 1),(t 2+100,f 2)}，这两个资源用于TB2初传和重传1的传输。同理，在TB1重传1中发送的第一侧行控制信息，也利用“Resource reservation period”域预留了TB2重传1和重传2的时频资源。在NR V2X中，“Resource reservation period”域可能的取值为0、1-99、100、200、300、400、500、600、700、800、900、1000毫秒，相比较LTE(Long Term Evaluation，长期演进)V2X更为灵活。但在每个资源池中，只配置了其中的e种取值，终端设备根据所用的资源池确定可能使用的值。记资源池配置中的e种取值为资源预留周期集合M，示例性地，e小于等于16。
此外，通过网络配置或预配置，上述TB间的预留可以以资源池为单位激活或去激活。当激活TB间的预留时，第一侧行控制信息中包括“Resource reservation period”域。当去激活TB间的预留时，第一侧行控制信息中不包括“Resource reservation period”域。在激活TB间的预留时，一般情况下，在触发资源重选之前，终端设备所用的“Resource reservation period”域的取值，即资源预留周期都不会变，终端设备每发送一次第一侧行控制信息，都利用其中的“Resource reservation period”域预留下个周期的资源，用于另一个TB的传输，从而达到周期性地半持续传输。
当终端设备工作在上述模式B下，终端设备可以通过侦听其他终端设备发送的PSCCH，获取其他终端设备发送的第一侧行控制信息，从而得知其他终端设备所预留的资源。终端设备在进行资源选择时，会排除其他终端设备预留的资源，从而避免资源碰撞。
在NR V2X系统中，上述模式B下，终端设备需要自行选择资源。
如图4所示，终端设备在时隙n触发资源选择或重选或时隙n是高层触发物理层上报候选资源集合的时隙，资源选择窗10从n+T 1开始，到n+T 2结束。0<＝T 1<＝T proc,1，当子载波间隔是15，30，60，120kHz时，T proc,1为3，5，9，17个时隙。T 2min<＝T 2<＝业务的剩余时延预算，T 2min的取值集合为{1,5,10,20}*2 μ个时隙，其中μ＝0,1,2,3对应于子载波间隔是15，30，60，120kHz的情况，终端设备根据自身待发送数据的优先级从该取值集合中确定T 2min。例如当子载波间隔是15kHz时，终端设备根据自身待发送数据的优先级从集合{1,5,10,20}中确定T 2min。当T 2min大于等于业务的剩余时延预算时，T 2等于业务的剩余时延预算。剩余时延预算即数据的时延要求的对应时刻与当前时刻的差值。例如时隙n到达的数据包，时延要求为50毫秒，假设一个时隙为1毫秒，如果当前时刻为时隙n，则剩余时延预算为50毫秒，若当前时刻为时隙n+20，则剩余时延预算为30毫秒。
终端设备在n-T 0到n-T proc,0进行资源侦听(不包括n-T proc,0)，T 0的取值为100或1100毫秒。当子载波间隔是15，30，60，120kHz时，T proc,0为1，1，2，4个时隙。可选地，终端设备在资源侦听窗内属于其所用资源池的时隙中进行资源侦听。可选地，终端设备在每个时隙(除了自己的发送时隙)都会侦听其他终端设备发送的第一侧行控制信息，当时隙n触发资源选择或重选后，终端设备使用n-T 0到n-T proc,0资源侦听的结果。
Step 1：终端设备将资源选择窗10内所有属于终端设备所用资源池的可用资源作为资源集合A，集合A中的任意一个资源记为R(x,y)，x和y分别指示资源的频域位置和时域位置。记集合A中资源的初始数量为M total。终端设备根据资源侦听窗20内的未侦听时隙(Step 1-1)和/或资源侦听窗20内的资源侦听结果(Step 1-2)对资源集合A中的资源进行排除。终端设备判断资源R(x,y)或与资源R(x,y)对应的一系列周期性资源是否与Step 1-1中根据未侦听时隙确定的时隙或Step 1-2中根据侦听到的第一侧行控制信息确定的资源重叠，若重叠则从资源 集合A中排除资源R(x,y)。
Step 1-1：如果终端设备在资源侦听窗20内时隙t m发送数据，没有进行侦听，则终端设备将根据时隙t m和终端设备所用资源池中每一种允许的资源预留周期，以该资源预留周期为间隔，确定对应的Q个时隙。若该Q个时隙与资源R(x,y)或与资源R(x,y)对应的一系列周期性资源重叠，则从资源集合A中排除资源R(x,y)。上述Q＝1或者

(代表向上取整)。Tscal等于T 2转化为毫秒后的值。Prx为终端设备所用资源池允许的资源预留周期的一种。可选地，与资源R(x,y)对应的一系列周期性资源为R(x,y+j*Ptxlg)，j＝0,1,2,…,Cresel-1。其中Cresel与终端设备生成的随机计数值相关，Ptxlg为Ptx转化为逻辑时隙后的数目。Ptx为终端设备的资源预留周期。例如图4子图(a)中为Cresel为3的情况，表示与资源R(x,y)对应的3个周期性资源(包括R(x,y))。可选地，当Prx<Tscal和/或n1-m小于或等于Prxlg时，
Figure PCTCN2021142659-appb-000008
其中，Prxlg为Prx转化为逻辑时隙后的数目。可选地Q＝1。如果时隙n在终端设备所用资源池内，则t n1为n，否则t n1为n之后第一个属于终端设备所用资源池的时隙。可选地，所述Q个时隙为t m+q*Prxlg，其中q为1,2,…,Q。
可选地，终端设备的资源池中的时隙为(t 1，t 2，…，t N)，即上述t m，t n1，t m+q*Prxlg为资源池中的时隙，R(x,y+j*Ptxlg)对应的时隙也为资源池中的时隙。
例如图4中的子图(a)，终端设备在时隙t m没有进行侦听，依次根据所用资源池配置中的资源预留周期集合M中每一种资源预留周期进行资源排除，对于其中某个资源预留周期1，假定Q值计算为2，则对应的Q个时隙为图4子图(a)中从时隙t m映射的以资源预留周期1为间隔接下来的2个以横线阴影标识的时隙。对于其中某个资源预留周期2，假定Q值计算Q＝1，则对应的Q个时隙为图4子图(a)中从时隙t m映射的以资源预留周期2为间隔的接下来的1个点状阴影标识的时隙。
终端设备将判断每一种预留周期对应的Q个时隙，是否与资源R(x,y)或与资源R(x,y)对应的一系列周期性资源重叠，若重叠则从资源集合A中排除资源R(x,y)。
可选地，当终端设备所用资源池去激活TB间的预留时，终端设备可以不执行上述Step 1-1。
可选地，当执行完Step1-1后，如果资源集合A中剩余资源小于M total*X，则将资源集合A初始化为资源选择窗10内所有属于终端设备所用资源池的可用资源再执行Step1-2。
Step 1-2：如果终端设备在资源侦听窗20的时隙t m内侦听到PSCCH中传输的第一侧行控制信息，测量该PSCCH的SL-RSRP(Sidelink Reference Signal Received Power，侧行参考信号接收功率)或者该PSCCH调度的PSSCH的SL-RSRP(即与该PSCCH在同一时隙中发送的PSSCH的SL-RSRP)。
如果测量的SL-RSRP大于SL-RSRP阈值，且终端设备所用资源池激活TB间的资源预留，则终端设备将根据时隙t m和侦听到的第一侧行控制信息中携带的资源预留周期，以该资源预留周期为间隔，确定对应的Q个时隙。终端设备假定在该Q个时隙中也收到了相同内容的第一侧行控制信息。终端设备将判断在时隙t m收到的第一侧行控制信息和这些假定收到的Q个第一侧行控制信息的“Time resource assignment”和“Frequency resource assignment”域指示的资源与资源R(x,y)或与资源R(x,y)对应的一系列周期性资源是否重叠，若重叠则从集合A中排除对应资源R(x,y)。上述Q＝1或者
Figure PCTCN2021142659-appb-000009
(代表向上取整)。Tscal等于T 2转化为毫秒后的值。Prx为侦听到的第一侧行控制信息中携带的资源预留周期。可选地，与资源R(x,y)对应的一系列周期性资源为R(x,y+j*Ptxlg)，j＝0,1,2,…,Cresel-1。其中Cresel与终端设备生成的随机计数值相关，Ptxlg为Ptx转化为逻辑时隙后的数目。Ptx为终端设备的资源预留周期。例如图4子图(b)中为Cresel为3的情况，表示与资源R(x,y)对应的3个周期性资源(包括R(x,y))。可选地，当Prx<Tscal和/或n1-m小于或等于Prxlg时，
Figure PCTCN2021142659-appb-000010
其中，Prxlg为Prx转化为逻辑时隙后的数目。如果时隙n在终端设备所用资源池内，则t n1为n，否则t n1为n之后第一个属于终端设备所用资源池的时隙。可选地，所述Q个时隙为t m+q*Prxlg，其中q为1,2,…,Q。
可选地，终端设备的资源池中的时隙为(t 1，t 2，…，t N)，即上述t m，t n1，t m+q*Prxlg为资源池中的时隙，R(x,y+j*Ptxlg)对应的时隙也为资源池中的时隙。
例如图4中的子图(b)，当终端设备所用资源池激活TB间的预留，如果终端设备在时隙t m资源E(v,m)上侦听到PSCCH中的第一侧行控制信息，该第一侧行控制信息中的资源预留周期为Prx，假定Q值计算为1，终端设备将假定在时隙t m+Prxlg上也收到了相同内容的第一侧行控制信息。终端设备将判断在时隙t m收到的第一侧行控制信息和假定在时隙t m+Prxlg收到的第一侧行控制信息的“Time resource assignment”和“Frequency resource assignment”域指示的资源1、2、3、4、5、6与资源R(x,y)或与资源R(x,y)对应的一系列周期性资源是否重叠，若重叠且满足RSRP条件则从资源集合A中排除资源R(x,y)。
如果终端设备测量的SL-RSRP大于SL-RSRP阈值，且终端设备所用资源池去激活TB间的资源预留，则终端设备只判断在时隙t m收到的第一侧行控制信息的“Time resource assignment”与“Frequency resource assignment”域指示的资源是否与资源R(x,y)或与资源R(x,y)对应的一系列资源重叠，若重叠则从资源集合A中排除资源R(x,y)。
例如图4中的子图(b)，当终端设备所用资源池去激活TB间的预留，如果终端设备在时隙t m资源E(v,m)上侦听到PSCCH中的第一侧行控制信息，则终端设备判断该第一侧行控制信息中“Time resource assignment”和“Frequency resource assignment”域指示的资源1、2、3与资源R(x,y)或与资源R(x,y)对应的一系列周期性资源是否重叠，若重叠且满足RSRP条件则从资源集合A中排除资源R(x,y)。
如果在上述资源排除后资源集合A中剩余资源不足M total*X，则将SL-RSRP阈值抬升3dB，重新执行Step 1。物理层将资源排除后的资源集合A作为候选资源集合上报给高层。
Step 2：高层从上报的候选资源集合中随机选择资源发送数据。即终端设备从候选资源集合中随机选择资源发送数据。
需要注意的是：
1.上述RSRP阈值是由终端设备侦听到的PSCCH中携带的优先级P1和终端设备待发送数据的优先级P2决定的。终端设备所用资源池的配置中包含一张SL-RSRP阈值表，该SL-RSRP阈值表包含了所有优先级组合对应的SL-RSRP阈值。资源池的配置可以是网络配置或者预配置的。
例如，如表1所示，假设P1与P2的优先级等级可选值均为0-7，则不同优先级组合对应的SL-RSRP阈值用γ ij表示，其中，γ ij中的i为优先级等级P1的取值，j为优先级等级P2的取值。
表1：SL-RSRP阈值表
Figure PCTCN2021142659-appb-000011
当终端设备侦听到其他终端设备发送的PSCCH，获取该PSCCH中传输的第一侧行控制信息中携带的优先级P1以及待发送数据的优先级P2，终端设备通过查表1的方式确定SL-RSRP阈值。
2.终端设备利用测量到的PSCCH-RSRP还是该PSCCH调度的PSSCH-RSRP与SL-RSRP阈值进行比较，取决于终端设备所用资源池的资源池配置。资源池的配置可以是网络配置或 者预配置的。
3.上述X，X可能的取值为{20％,35％,50％}。终端设备所用资源池的配置中包含优先级与上述可能取值的对应关系，终端设备根据待发送数据的优先级及该对应关系，确定X的值。资源池配置可以是由网络配置或者预配置。
4.将资源预留周期转化为逻辑时隙：
在上文中提到，终端设备发送第一侧行控制信息指示时频资源，预留接下来将要使用的资源。而进行资源选择的终端设备在侦听时，会解码其他终端设备发送的第一侧行控制信息，获知其他终端设备所预留的资源，在资源选择时排除对应资源，从而避免资源碰撞。进行资源选择的终端设备在进行资源排除时，针对解码的第一侧行控制信息中的“resource reservation period”域指示的物理时间(例如100毫秒)，会将其转化为相应的逻辑时隙数目后，再利用该逻辑时隙的数目进行资源排除：
Figure PCTCN2021142659-appb-000012
上述公式中，Prsvp为资源预留周期，如Prsvp为终端设备侦听到的第一侧行控制信息中“resource reservation period”指示的资源预留周期，或为资源池中允许的资源预留周期，或为终端设备的资源预留周期，P’rsvp为计算出的对应的逻辑时隙数目。T’max为一个SFN(System Frame Number，系统帧号)周期或10240毫秒内属于终端设备的资源池或发送资源池的时隙数目。
上述介绍为NR-V2X中的一种SL通信方式，即终端设备通过资源侦听自主选取传输资源，自行在侧行链路上进行数据传输。该SL通信的方式也可应用在手持终端与手持终端间的直接通信，行人与车辆间的直接通信等各种SL通信中。
上述介绍的终端设备通过资源侦听自主选取传输资源的方式并未考虑到节约功耗，部分侦听的资源选择方法就是针对例如手持终端这种功耗敏感的终端设计的节能省电的资源选择方式，其主要通过限制进行资源选择的时间单元数目与进行资源侦听的时间单元数目，以达到节能省电的目的。
接下来结合图5说明一种部分侦听的资源选择算法。终端设备根据在资源选择窗内确定的至少Y个时隙以及资源池配置中的资源预留周期集合M或M的子集，确定对应的侦听时隙。具体地，对于所述至少Y个时隙内的任意一个时隙t y，终端设备确定的侦听时隙为t y-k*Preserve。其中t 1,t 2,…,t N表示属于资源池的时隙。当高层配置了periodicSensingOccasionReservePeriodList参数时，Preserve对应于periodicSensingOccasionReservePeriodList中包括的资源预留周期，否则Preserve对应于资源池中允许的全部资源预留周期。或者当高层配置了periodicSensingOccasionReservePeriodList参数时，Preserve对应于periodicSensingOccasionReservePeriodList中包括的资源预留周期转化为逻辑时隙后的值，否则Preserve对应于资源池中允许的全部资源预留周期转化为逻辑时隙后的值。
对于Preserve对应的取值中的一种取值，当additionalPeriodicSensingOccasion没有配置时，k为在时隙t y0-(T proc,0+T proc,1)前的最近的侦听时隙(记为侦听时隙U)对应的值，或者说k为使t y-k*Preserve在t y0-(T proc,0+T proc,1)之前的最小值(记为取值R)。当配置了additionalPeriodicSensingOccasion时，k还包括在侦听时隙U之前上一个周期性侦听时隙对应的值，或者说还包括取值R+1。t y0为确定的至少Y个时隙内第一个时隙，或者说时域位置最靠前的时隙。
因此对于确定的至少Y个时隙中的每一个时隙t y，终端设备根据Preserve对应的值中的每一种取值，确定对应的k值，从而确定该t y对应的侦听时隙t y-k*Preserve。终端设备应在确定的侦听时隙中进行侦听。
可选地，终端设备从[n+T A，n+T B]进行持续性侦听，n+T A等于t y0前第M个逻辑时隙(示例性地，n+T A等于t y0- M)，n+T B为t y0前T proc,0+T proc,1个时隙(示例性地，n+T B＝t y0-(T proc,0+T proc,1) 或t y0-(T proc,0+T proc,1)-1)。M为31或由网络配置或预配置或由终端设备实现。
例如图5，假设资源池中允许的资源周期为P1,P2,P3，资源池配置中配置了periodicSensingOccasionReservePeriodList包括P1和P2，则Preserve对应P1和P2转化为逻辑时隙后的值P1lg和P2lg。且假设资源池配置中配置了additionalPeriodicSensingOccasion参数。时隙n为高层触发物理层上报候选资源集合的时隙，资源选择窗为n+T 1到n+T 2，终端设备在资源选择窗中确定2个时隙，包括t y0和t y1。对于t y0，确定的侦听时隙为t y0-k*Preserve。当Preserve等于P1lg时，由于t y0-P1lg在t y0-(T proc,0+T proc,1)前，则k＝1和2，确定的侦听时隙为t y0-P1lg和t y0-2*P1lg。当Preserve等于P2lg时，由于t y0-P2lg在t y0-(T proc,0+T proc,1)前，则k＝1和2，确定的侦听时隙为t y0-P2lg和t y0-2*P2lg。对于t y1，确定的侦听时隙为t y1-k*Preserve。当Preserve等于P1lg时，由于t y1-P1lg在t y0-(T proc,0+T proc,1)之后，t y1-2*P1lg在t y0-(T proc,0+T proc,1)前，则k＝2和3，确定的侦听时隙为t y1-2*P1lg和t y1-3*P1lg。当Preserve等于P2lg时，由于t y1-P2lg在t y0-(T proc,0+T proc,1)前，则k＝1和2，确定的侦听时隙为t y1-P2lg和t y1-2*P2lg。可选的，n+T A为t y0- M，n+T B为t y0-(T proc,0+T proc,1)，终端设备从n+T A到n+T B进行持续侦听。终端设备根据上述侦听时隙内的侦听结果和上述持续性侦听时段内的侦听结果对确定的至少Y个时隙内的资源进行资源排除，在剩余资源中选择资源传输数据。
目前对于部分侦听的资源选择算法，资源排除大体上沿用V2X中的资源排除流程(如上文介绍的Step 1)，但相关细节标准还并未讨论，比如上述Q值如何计算。
从图5的示例中可以得知，目前标准支持配置additionalPeriodicSensingOccasion参数，使终端设备根据最近两次周期性的侦听时隙进行资源排除，例如根据图5中t y0-2*P2lg中的侦听结果对t y0中的资源进行排除。然而从上文内容中还可以得知，在Step 1流程中，Q多数情况下等于1。这会导致，即使配置了根据t y0-2*P2lg中的侦听结果对t y0中的资源进行排除，终端设备根据在t y0-2*P2lg中侦听到的侧行控制信息进行资源排除也根本无法排除t y0中的资源。例如图5中，终端设备在t y0-2*P2lg中侦听到资源预留周期为P2的侧行控制信息，计算Q为1，确定对应的Q个时隙为t y0-P2lg。终端设备根据在t y0-2*P2lg中收到的和在t y0-P2lg中假定收到的侧行控制信息中Time resource assignment和Frequency resource assignment域指示的资源根本无法排除时隙t y0中的资源。
因此，本申请分类讨论了配置additionalPeriodicSensingOccasion参数和没有配置additionalPeriodicSensingOccasion参数情况下Q值的计算。
请参考图6，其示出了本申请一个实施例提供的资源排除方法的流程图。该方法可应用于图1所示的网络架构中，例如该方法可以由终端设备执行。该方法可以包括如下几个步骤(610～620)中的至少一个步骤：
步骤610，根据侦听到侧行控制信息的第一时隙，确定第一时隙对应的Q个时隙；其中，如果配置了第一参数，则Q等于1或2或
Figure PCTCN2021142659-appb-000013
或
Figure PCTCN2021142659-appb-000014
第一参数用于指示额外的周期性侦听时隙，Prx为侧行控制信息中携带的资源预留周期，Tscal根据资源选择窗或选择时隙确定。
在本申请实施例中，第一参数用于指示额外的周期性侦听时隙。或者说，第一参数用于配置或确定额外的周期性侦听时隙。示例性地，第一参数为上文介绍的additionalPeriodicSensingOccasion参数。
在本申请实施例中，在配置了第一参数的情况下，Q除了可以等于1或
Figure PCTCN2021142659-appb-000015
之外，还可以等于2或
Figure PCTCN2021142659-appb-000016
这样能够避免在配置了额外的侦听时隙的情况下，也无法根据该额外的侦听时隙正确进行资源排除的问题，使得终端设备能够正确进行资源排除，提升了通信可靠性。
在本申请实施例中，假设m表示第一时隙，Prxlg为Prx转化为逻辑时隙后的数目，n1表示参考时隙。例如，m为第一时隙在资源池内的时隙索引，n1为参考时隙在资源池内的时 隙索引。假设(t 1，t 2，…，t N)表示属于资源池的时隙，第一时隙和参考时隙位于资源池内，则t m为第一时隙，t n1为参考时隙。另外，有关资源预留周期转化为逻辑时隙的算法，可参见上文中的介绍说明，此处不再赘述。
可选地，在配置了第一参数的情况下，Q的取值可以包括如下情况1～5中的至少一种：
情况1：如果m+Prxlg小于n1、m+2*Prxlg大于或等于n1且Prx小于Tscal，则
Figure PCTCN2021142659-appb-000017
示例性地，如果m+Prxlg＜n1、m+2*Prxlg≥n1且Prx＜Tscal，则
Figure PCTCN2021142659-appb-000018
也就是说，如果n1-m＞Prxlg、n1-m≤2*Prxlg且Prx＜Tscal，则
Figure PCTCN2021142659-appb-000019
情况2：如果m+Prxlg小于n1、m+2*Prxlg大于或等于n1且Prx大于或等于Tscal，则Q＝2。示例性地，如果m+Prxlg＜n1、m+2*Prxlg≥n1且Prx≥Tscal，则Q＝2。也就是说，如果n1-m＞Prxlg、n1-m≤2*Prxlg且Prx≥Tscal，则Q＝2。
情况3：如果m+Prxlg大于或等于n1且Prx小于Tscal，则
Figure PCTCN2021142659-appb-000020
示例性地，如果m+Prxlg≥n1且Prx＜Tscal，则
Figure PCTCN2021142659-appb-000021
也就是说，如果n1-m≤Prxlg且Prx＜Tscal，则
Figure PCTCN2021142659-appb-000022
情况4：如果m+Prxlg大于或等于n1且Prx大于或等于Tscal，则Q＝1。示例性地，如果m+Prxlg≥n1且Prx≥Tscal，则Q＝1。也就是说，如果n1-m≤Prxlg且Prx≥Tscal，则Q＝1。
情况5：如果m+Prxlg小于n1且m+2*Prxlg小于n1，则Q＝1或2。示例性地，如果m+Prxlg＜n1且m+2*Prxlg＜n1，则Q＝1或2。也就是说，如果n1-m＞Prxlg且n1-m＞2*Prxlg，则Q＝1或2。需要说明的是，对于该情况5，其条件“m+Prxlg小于n1”可以省去，也即如果m+2*Prxlg小于n1，则Q＝1或2。因为在m+2*Prxlg小于n1的情况下，m+Prxlg必然也是小于n1的。
在示例性实施例中，如图7所示，其示例性示出了一种确定Q的取值的流程图。例如，该流程如下：
S1：判断m+Prxlg是否大于或等于n1；如果否，则执行下述步骤S2；如果是，则执行下述步骤S4；
S2：判断m+2*Prxlg是否大于或等于n1；如果是，则执行下述步骤S3；如果否，则确定Q＝1或2(对应于上述情况5)；
S3：判断Prx是否小于Tscal；如果是，则
Figure PCTCN2021142659-appb-000023
(对应于上述情况1)；如果否，则Q＝2(对应于上述情况2)；
S4：判断Prx是否小于Tscal；如果是，则
Figure PCTCN2021142659-appb-000024
(对应于上述情况3)；如果否，则Q＝1(对应于上述情况4)。
需要说明的是，上述图7仅是示例性给出了一种可能的确定Q值的判定流程，本申请并不限定还可以基于其他判定流程来确定Q值，例如先判断m+2*Prxlg是否大于或等于n1，或者先判断Prx是否小于Tscal等等，本申请对此不作限定。另外，图7给出的示例中，包含了情况1至情况5共五种判定结果，在一些其他可能的示例中，也可能仅包含情况1至情况5中的任意一种或者多种，本申请对此不作限定。

否则Q＝1。示例性地，如果m+Prxlg≥n1且Prx＜Tscal，则
Figure PCTCN2021142659-appb-000026
否则Q＝1。也就是说，如果n1-m≤Prxlg且Prx＜Tscal，则
Figure PCTCN2021142659-appb-000027
否则Q＝1。
可选地，参考时隙由第一时间单元确定。第一时间单元位于第一时域区间之内，或者第一时间单元是高层触发物理层进行资源集合上报的时隙。其中，第一时域区间的起始位置包括终端设备确定的时域上最后一个侦听时隙，第一时域区间的结束位置包括终端设备确定的时域上第一个选择时隙。需要说明的是，时域上最后一个侦听时隙，是指在时域上分布的多个侦听时隙中，时域位置最靠后的一个侦听时隙。如果按照时域位置由前向后的顺序，侦听时隙的索引逐渐增大，那么时域上最后一个侦听时隙，就是索引最大的侦听时隙。类似地，时域上第一个选择时隙，是指在时域上分布的多个选择时隙中，时域位置最靠前的一个选择 时隙。如果按照时域位置由前向后的顺序，选择时隙的索引逐渐增大，那么时域上第一个选择时隙，就是索引最小的选择时隙。本申请中其他地方出现的类似描述，请参照这里的解释，将不作重复说明。

可选地，上述资源池为终端设备的资源池，或终端设备的发送资源池，或终端设备所使用的资源池。
例如，记(t 1，t 2，…，t N)表示属于资源池的时隙。上述n1由第一时间单元确定。如果第一时间单元在资源池内，则t n1为第一时间单元。如果第一时间单元不在资源池内，则t n1为第一时间单元之后第一个属于资源池的时隙。
可选地，在第一时间单元位于第一时域区间之内的情况下，第一时间单元为：终端设备确定的时域上最后一个侦听时隙，或终端设备确定的时域上最后一个侦听时隙加第一偏移量，或终端设备确定的时域上第一个选择时隙，或终端设备确定的时域上第一个选择时隙减第二偏移量。
可选地，第一偏移量由网络配置，或预配置，或取决于终端设备的实现，或为标准规定的预设值。示例性地，第一偏移量为1个时隙，或T proc,0，或T proc,0+T proc,1。
可选地，第二偏移量由网络配置，或预配置，或取决于终端设备的实现，或为标准规定的预设值。示例性地，第一偏移量为1个时隙，或T proc,0，或T proc,0+T proc,1。
可选地，Tscal为资源选择窗的结束时隙与第一时间单元的差值转化为毫秒后的值，或为终端设备确定的最后一个选择时隙与第一时间单元的差值转化为毫秒后的值。
可选地，终端设备在时隙t m侦听到侧行控制信息，示例性地，该侧行控制信息为第一侧行控制信息。有关第一侧行控制信息的介绍说明可参见上文，此处不再赘述。
可选地，第一时隙对应的Q个时隙为t m+q*Prxlg，q＝1,2,…,Q。

可选地，选择时隙是终端设备在资源选择窗内确定的部分时隙。示例性地，选择时隙是终端设备在资源选择窗内确定的Y个或Y’个候选时隙。其中，Y个候选时隙是针对周期性部分侦听(periodic-based partial sensing)确定的时隙，Y’个候选时隙是针对持续性部分侦听(contiguous partial sensing)确定的时隙。
需要说明的是，在本申请中，选择时隙是指从资源选择窗中确定的时隙，用于提供候选资源，其英文可称为selected candidate slots或candidate slots；侦听时隙是指终端设备侦听侧行控制信息的时隙，其英文可称为sensing occasions。当然，本申请中对选择时隙和侦听时隙的中英文名称不作限定，其在一些可能的情况下，也可以称作其他名称。

另外，上述第一时隙是否为依据第一参数确定的侦听时隙，是指第一时隙是否为依据第一参数确定的额外的周期性侦听时隙。

下面，结合几个示例性实施例，对本申请技术方案进行介绍说明。
在一个示例中，如图9，假设资源池中允许的资源预留周期为P1,P2,P3，资源池中配置了periodicSensingOccasionReservePeriodList包括P1和P2，且假设资源池配置中配置了additionalPeriodicSensingOccasion参数。记(t 1,t 2,t 3,t 4….)表示属于资源池的时隙。

终端设备初始化候选资源集合为t y0和t y1中全部的可用资源，终端设备根据由t y0和t y1确定的侦听时隙以及[n+T A,n+T B]中侦听到的第一侧行控制信息对所述候选资源集合中的资源进行排除。记候选资源集合中任意一个资源为R(x,y)，x表示资源的频域位置，y表示资源的时域位置。假设第一时间单元为t y0-(T proc,0+T proc,1)，且t y0-(T proc,0+T proc,1)位于资源池内，则t n1等于t y0-(T proc,0+T proc,1)。Tscal等于资源选择窗结束时隙n+T 2减去t y0-(T proc,0+T proc,1)。
假设终端设备在时隙t y1-2*P2lg收到第一侧行控制信息1，测量该第一侧行控制信息1所在的PSCCH或该PSCCH调度的PSSCH的SL-RSRP。假设第一侧行控制信息1中携带的资源预留周期为P2，终端设备根据时隙t y1-2*P2lg以及P2确定对应的Q个时隙。示例性地，由于y1-2*P2lg+P2lg小于n1，y1-2*P2lg+2*P2lg大于n1且P2大于Tscal，则Q等于2。则终端设备假设在时隙t y1-2*P2lg+P2lg和时隙t y1-2*P2lg+2*P2lg即时隙t y1-P2lg和t y1内均收到了相同内容的第一侧行控制信息1。若在时隙t y1-2*P2lg收到第一侧行控制信息1和t y1-P2lg和t y1中假定收到的第一侧行控制信息中Time resource assignment域和Frequency resource assignment域指示的资源与R(x,y)或R(x,y+j*Ptxlg)重叠且测量的SL-RSRP大于RSRP阈值，则从候选资源集合中排除资源R(x,y)。其中j＝0,1,…,Cresel-1。Cresel与终端设备生成的随机计数值相关。Ptxlg是Ptx转化为逻辑时隙后的数目。Ptx为终端设备的资源预留周期。

在另一个示例中，如图10，假设资源池中允许的资源预留周期为P1,P2,P3，资源池中未配置periodicSensingOccasionReservePeriodList，且未配置additionalPeriodicSensingOccasion参数。记(t 1,t 2,t 3,t 4….)表示属于资源池的时隙。
时隙n为高层触发物理层上报候选资源集合的时隙，资源选择窗为n+T 1到n+T 2，示例性地，T 1和T 2可参照上文说明。终端设备在资源选择窗中确定2个候选时隙，包括t y0和t y1。终端设备根据t y0和t y1确定的侦听时隙如图10所示，具体确定的细节可参照背景部分，终端设备应在根据t y0和t y1确定的侦听时隙中进行侦听。此外，终端设备还在[n+T A,n+T B]间进行持续性侦听，n+T A等于t y0-31，n+T B等于t y0-(T proc,0+T proc,1)。可选地，终端设备在[n+T A,n+T B]内属于资源池的时隙中进行侦听。
终端设备初始化候选资源集合为t y0和t y1中全部的可用资源，终端设备根据由t y0和t y1确定的侦听时隙以及[n+T A,n+T B]中侦听到的第一侧行控制信息对所述候选资源集合中的资源进行排除。记候选资源集合中任意一个资源为R(x,y)，x表示资源的频域位置，y表示资源的时域位置。假设第一时间单元为t y0-(T proc,0+T proc,1)，且t y0-(T proc,0+T proc,1)位于资源池内，则t n1等于t y0-(T proc,0+T proc,1)。Tscal等于资源选择窗结束时隙n+T 2减去t y0-(T proc,0+T proc,1)。
假设终端设备在时隙t y1-2*P1lg收到第一侧行控制信息1，测量该第一侧行控制信息1所在的PSCCH或该PSCCH调度的PSSCH的SL-RSRP。假设第一侧行控制信息1中携带的资源 预留周期为P1，终端设备根据时隙t y1-2*P1lg以及P1确定对应的Q个时隙。示例性地，由于y1-2*P1lg+P1lg大于n1且P1小于Tscal，则Q等于
