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。
本申请实施例中的“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。本申请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。在本申请实施例中，“终端设备”和“UE”通常表达同一含义，两者可以混用，但本领域技术人员可以理解其含义。
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。
1.SL(Sidelink，侧行链路)传输
设备到设备通信是一种侧行链路传输技术，与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同。例如车联网系统中也采用设备到设备直接通信的方式，因此具有更高的频谱效率以及更低的传输时延。关于设备到设备的通信，3GPP定义了两种传输模式：模式A和模式B。
模式A：如图2子图(a)所示，终端设备13的传输资源是由接入网设备14(如基站)分配的，终端设备13根据接入网设备14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14既可以为终端设备13分配单次传输的传输资源，也可以为终端设备13分配半静态传输的传输资源。
模式B：如图2子图(b)所示，终端设备13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13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系统和LTE(Long Term Evaluation，长期演进)V2X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)。
2.NR V2X物理层结构
NR V2X系统中SL通信的物理层结构如图3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)用于承载数据和第三侧行控制信息。PSCCH和PSSCH在同一时隙中发送。上述第一侧行控制信息和第三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，还承载第三侧行控制信息，第三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。
示例性地，第一侧行控制信息为1st-stage-SCI，即第一阶SCI(Sidelink Control Information，侧行链路控制信息)。
示例性地，第三侧行控制信息为2nd-stage-SCI，即第二阶SCI。
3.NR V2X中的资源预留
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4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4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4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4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 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。
4.NR V2X侦听的资源选择方法
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5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
Figure PCTCN2022082184-appb-000001
(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与R(x,y)所占的频域资源相同的以一定时间间隔映射的一系列周期性资源，如图5子图(a)和子图(b)所示。例如，该时间间隔是终端设备自己的资源预留周期。且上述与资源R(x,y)对应的一系列周期性资源包括资源R(x,y)。
例如图5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5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。若这2个横线阴影标识的时隙与资源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)。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5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。若该点状阴影标识的时隙与资源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)。
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，且终端设备侦听到的第一侧行控制信息中包括“Resourcereservationperiod”域，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将收到的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 PCTCN2022082184-appb-000002
(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。
例如图5中的子图(b)，如果终端设备在时隙t m侦听到PSCCH中的第一侧行控制信息，该第一侧行控制信息中包括“Resourcereservationperiod”域，该域指示的资源预留周期为Prx，假定Q值计算为1，终端设备将假定在以时隙t m为起点、以Prx为间隔的下1个时隙(即资源4所在的时隙)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将收到的第一侧行控制信息的“Timeresourceassignment”和“Frequencyresourceassignment”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，且终端设备侦听到的第一侧行控制信息不包括“Resourcereservationperiod”域，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“Timeresourceassignment”与“Frequencyresourceassignment”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5中的子图(b)中，如果终端设备在时隙t m的PSCCH中的侦听到第一侧行控制信息，该第一侧行控制信息不包括“Resourcereservationperiod”域，则终端设备判断该第一侧行控制信息中“Timeresourceassignment”和“Frequencyresourceassignment”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 PCTCN2022082184-appb-000003
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 PCTCN2022082184-appb-000004
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。
5.LTE V2X物理层结构
LTE V2X系统中SL通信的物理层结构如图6所示。PSCCH用于承载第二侧行控制信息，PSSCH用于承载数据。PSCCH和PSSCH在同一子帧中发送。在LTE V2X中，PSCCH与PSSCH在频域上可以是连续的，也可以是非连续的。
上述第二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。
另外，关于LTE V2X系统中的资源预留以及基于侦听的资源选择方法，与NR V2X系统中的相类似，本申请对此不作过多赘述。这里仅做一些简单介绍：在LTE V2X系统中，利用第二侧行控制信息中的第一至第三信息域指示同一个TB内的重传资源。可选地，还利用第二侧行控制信息中的第四信息域指示另一个TB的传输资源。其中，第一信息域是指第二侧行控制信息中的Frequency resource location of the initial transmission and retransmission(即初传和重传的频域资源位置指示)，第二信息域是指第二侧行控制信息中的Time gap between initial transmission and retransmission(即初传与重传间的时间间隔)，第三信息域是指第二侧行控制信息中的Retransmission index(即重传索引)，第四信息域是指第二侧行控制信息中的Resourcereservation(即资源预留)。
6.NR V2X中的Re-evaluation(重评估)和Pre-emption(资源抢占)机制
在NR-V2X中还支持在完成资源选择之后，对于已选但未通过发送第一侧行控制信息指示的资源进行重评估(Re-evaluation)。
如图7所示，资源x、y、z、u、v是终端设备在时隙n已经选择的时频资源，资源y位于时隙m。对于终端设备即将在资源y发送第一侧行控制信息进行首次指示的资源z和u(资源y之前已经被资源x中的第一侧行控制信息指示)，终端设备至少在时隙m-T 3执行一次上述Step 1，即至少在时隙m-T 3按上述确定资源选择窗10与资源侦听窗20，并执行上述Step 1对资源选择窗10内的资源进行排除，得到候选资源集合。如果资源z和/或u不在候选资源集合中，则终端设备执行上述Step 2重选资源z和u中不在候选资源集合中的时频资源，取决于终端设备实现，终端设备也可以重选任何已经选择但未通过发送第一侧行控制信息指示的资源，例如资源z、u和v中的任意一个或多个资源。上述T 3等于T proc,1。图7中虚线箭头表示即将发送第一侧行控制信息指示，实线箭头表示已经发送第一侧行控制信息指示。
此外，NR-V2X还支持资源抢占(Pre-emption)机制。在NR-V2X中，关于资源抢占机制的结论从被抢占终端的角度描述。在完成资源选择后，终端设备仍然持续侦听第一侧行控制信息，如果已经选择的并且已经通过发送第一侧行控制信息指示的资源满足以下三个条件，则表示该资源被其他终端设备抢占，终端设备针对该资源触发资源重选：
1.终端设备已选且已指示的资源不在候选资源集合内。
2.侦听到的第一侧行控制信息中指示的资源与终端设备已选且已指示的资源重叠，且该侦听到的第一侧行控制信息对应的PSCCH的SL-RSRP或该PSCCH调度的PSSCH的SL-RSRP大于SL RSRP阈值。
3.侦听到的第一侧行控制信息中携带的优先级比终端设备待发送数据的优先级高。或者侦听到的第一侧行控制信息中携带的优先级比终端设备待发送数据的优先级高，且侦听到的第一侧行控制信息中携带的优先级比门限值U高，U取决于资源池配置，资源池可以由网络配置或预配置。
如图8所示，资源w、x、y、z、v是终端设备在时隙n已经选择的时频资源，资源x位于时隙m。对于终端设备即将在资源x上发送第一侧行控制信息指示的且已经被终端设备之前发送的第一侧行控制信息指示的资源x和y，终端设备至少在时隙m-T 3执行一次上述Step 1，即至少在时隙m-T 3按上述确定资源 选择窗10与资源侦听窗20，并执行上述Step 1对资源选择窗10内的可用资源进行排除，确定候选资源集合。如果资源x和/或y满足上述三个条件，则终端设备执行Step 2重选资源x和y中满足上述3个条件的时频资源。此外，当触发资源重选后，取决于终端设备实现，终端设备可以重选任何已选择但未通过发送第一侧行控制信息指示的资源，比如资源z和v中的任意几个。上述T 3等于T proc,1。
目前R18 Sidelink标准的研究项目之一为LTE Sidelink(简称LTE SL)与NR Sidelink(简称NR SL)在重叠频段上的共存。当LTE SL UE与NR SL UE使用重叠的资源池时，相互之间如何避免资源碰撞标准还未讨论。一方面，LTE SL UE并不会解码NR SL UE的侧行控制信息，因此无法获知NR SL UE的资源预留信息，即无法避免与NR SL UE间的资源碰撞。另一方面，NR SL UE可能既包含LTE SL的模块也包含NR SL的模块，因此既可以解码LTE SL UE的侧行控制信息又可以解码NR SL UE的侧行控制信息，因此在该情况下可以避免与LTE SL UE以及NR SL UE间的资源碰撞。
从上文介绍可以得知，NR SL中支持Re-evaluation机制和Pre-emption机制。当NR SL和LTE SL部署在重叠频段时，NR SL UE如何根据收到的LTE SL UE和NR SL UE的侧行控制信息对已选资源进行重评估(Re-evaluation)，以及如何根据收到的LTE SL UE和NR SL UE的侧行控制信息判断已选资源是否被抢占，还需进一步研究。
下面，将通过几个示例性实施例对本申请技术方案进行介绍说明。
请参考图9，其示出了本申请一个实施例提供的资源重选方法的流程图。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步骤：

其中，第一侧行控制信息和第二侧行控制信息是两个不同的侧行控制信息。
为了便于描述，在本申请中除特别说明之外，将“第一资源不在第一资源集合内”记为“条件1”；将“第二资源与根据第一侧行控制信息或第二侧行控制信息确定的资源重叠，且满足RSRP阈值条件”记为“条件2”；将“第一侧行控制信息或第二侧行控制信息指示的优先级高于数据传输的优先级和/或高于优先级阈值”记为“条件3”。也就是说，第一条件包括条件1、条件2和条件3中的至少一种。

在一些实施例中，第一侧行控制信息和第二侧行控制信息是两个具有不同功能的侧行控制信息。可选地，第一侧行控制信息具有第一功能，第二侧行控制信息具有第二功能，第一功能和第二功能是两种不同的功能。示例性地，第一侧行控制信息用于调度PSSCH和第三侧行控制信息，第二侧行控制信息用于调度PSSCH。第三侧行控制信息承载在PSSCH中，第三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。可选地，第三侧行控制信息为2nd-stage-SCI，即第二阶SCI。当然，此处仅以第一功能为调度PSSCH和第三侧行控制信息的功能，且第二功能为调度PSSCH的功能为例，进行举例性说明，本申请并不限定第一功能和第二功能还可以是其他组合方式。
在一些实施例中，第一侧行控制信息和第二侧行控制信息是两个具有不同格式的侧行控制信息。可选地，第一侧行控制信息具有第一格式，第二侧行控制信息具有第二格式，第一格式和第二格式是两种不同的格式。示例性地，第一侧行控制信息的格式为SCI format 1-A，第二侧行控制信息的格式为SCI format 1。当然，此处仅以第一格式为SCI format 1-A，且第二格式为SCI format 1为例，进行举例性说明，本申请并不限定第一格式和第二格式还可以是其他组合方式。
在一些实施例中，第一侧行控制信息和第二侧行控制信息是两个包括不同的域的侧行控制信息。可选地，第一侧行控制信息包括第一域，第二侧行控制信息包括第二域，第一域和第二域是两种不同的信息域。示例性地，第一侧行控制信息包括DMRS(Demodulation Reference Signal，解调参考信号)图样指示域和 DMRS端口数指示域，第二侧行控制信息包括重传索引以及初传和重传之间的时间间隔的指示域。当然，此处仅以第一域包括DMRS图样指示域和DMRS端口数指示域，且第二域包括重传索引以及初传和重传之间的时间间隔的指示域为例，进行举例性说明，本申请并不限定第一域和第二域还可以是其他组合方式。
在一些实施例中，第一资源为终端设备已经选择(简称为“已选”)的资源，该资源可以是时频资源，如第一资源为终端设备已选的时频资源。可选地，对于Re-evaluation(重评估)场景，第一资源为终端设备已选但未通过发送第一侧行控制信息指示的资源，如第一资源为终端设备已选但未通过发送第一侧行控制信息指示的时频资源。可选地，对于Pre-emption(资源抢占)场景，第一资源为终端设备已选且已通过发送第一侧行控制信息指示的资源，如第一资源为终端设备已选且已通过发送第一侧行控制信息指示的时频资源。
在一些实施例中，第一资源由终端设备的高层配置给终端设备的物理层，物理层检测该第一资源是否满足第一条件，若该第一资源满足第一条件，则物理层向高层上报该第一资源，而后高层重选该上报的第一资源。可选地，若该第一资源不满足第一条件，则物理层可以不用向高层上报该第一资源。另外，第一资源可以是终端设备任意一个已选但未通过发送第一侧行控制信息指示的资源，或者是终端设备任意一个已选且已通过发送第一侧行控制信息指示的资源。高层可以配置一个或多个第一资源给物理层，物理层检测各个第一资源是否满足第一条件，物理层向高层上报其中满足第一条件的第一资源，而后高层重选该上报的第一资源。
本申请实施例提供的技术方案，终端设备在完成资源选择后，根据侦听到的第一侧行控制信息和第二侧行控制信息进行资源重选，由于第一侧行控制信息和第二侧行控制信息是两个不同的侧行控制信息，例如是两个不同通信系统中的侧行控制信息，因此采用该技术方案，能够在两个不同通信系统中的资源池重叠的场景下，使得第一通信系统中的终端设备已经选择的资源，避免与该第一通信系统中的其他终端设备以及第二通信系统中的终端设备所预留的资源发生冲突，特别是避免与高优先级的业务间的冲突，从而提升通信可靠性。
下面，针对条件1进行介绍说明。
在一些实施例中，第一资源不在第一资源集合内，是指第一资源集合中不包含第一资源。在一些实施例中，第一资源集合是终端设备根据第一侧行控制信息和第二侧行控制信息确定的候选资源集合，终端设备从该候选资源集合(也即第一资源集合)中选择传输资源，而后使用该选择的传输资源传输数据。可选地，终端设备可以从候选资源集合(也即第一资源集合)中随机选择传输资源，或者按照某种策略进行选择，本申请对此不作限定。
在一些实施例中，终端设备在根据第一侧行控制信息和第二侧行控制信息确定候选资源集合(也即第一资源集合)之后，对于终端设备已选的第一资源，终端设备判断该第一资源是否在第一资源集合内；如果第一资源在第一资源集合内，则终端设备可以使用该已选的第一资源传输数据；如果第一资源不在第一资源集合内，则终端设备可以重选(reselect)该第一资源，例如在第一资源集合中选择第三资源替代第一资源。
在一些实施例中，终端设备确定第一资源集合的方法如下：
确定资源选择窗和资源侦听窗；
将资源选择窗内的可用资源作为初始化的资源集合；
执行资源排除步骤，对资源集合中的资源进行排除，得到第一资源集合；其中，资源排除步骤包括：第一排除步骤和第二排除步骤，第一排除步骤用于根据资源侦听窗内侦听到的第一侧行控制信息进行资源排除，第二排除步骤用于根据资源侦听窗内侦听到的第二侧行控制信息进行资源排除。
在本申请实施例中，对资源选择窗所对应的时间区间不作限定。示例性地，资源选择窗可以采用NR V2X系统中的设计方式，例如资源选择窗从n+T 1开始，到n+T 2结束，其中时间单元n(如时隙n)是触发资源选择或重选或高层触发物理层上报候选资源集合的时间单元，T 1和T 2的说明可参见上文。可选地，在第一侧行控制信息为NR系统中的侧行控制信息的情况下，资源选择窗可以采用上述介绍的NR V2X系统中的设计方式。
可选地，资源侦听窗的数量可以是两个，也可以是一个。
可选地，在资源侦听窗的数量为两个的情况下，资源侦听窗包括第一资源侦听窗和第二资源侦听窗。终端设备侦听第一资源侦听窗内的第一侧行控制信息，以及侦听第二资源侦听窗内的第二侧行控制信息。其中，第一资源侦听窗和第二资源侦听窗是两个不同的资源侦听窗。例如，第一资源侦听窗对应的时间区间与第二资源侦听窗对应的时间区间不同。示例性地，第一资源侦听窗从n-T 00到n-T proc,0(不包括n-T proc,0)，T 00为1100或100毫秒，T proc,0参照上文介绍，第二资源侦听窗从n-T 10到n(不包括n)，T 10为1000毫秒，时间单元n(如时隙n)是触发资源选择或重选或高层触发物理层上报候选资源集合的时间单元。可选地， 在第一侧行控制信息为NR系统中的侧行控制信息的情况下，第一资源侦听窗采用NR V2X系统中的设计方式，如从n-T 00到n-T proc,0(不包括n-T proc,0)。可选地，在第二侧行控制信息为LTE系统中的侧行控制信息的情况下，第二资源侦听窗采用LTE V2X系统中的设计方式，从n-T 10到n(不包括n)。
可选地，在资源侦听窗的数量为一个的情况下，在一个示例中，资源侦听窗包括第一资源侦听窗，终端设备侦听第一资源侦听窗内的第一侧行控制信息和第二侧行控制信息；在另一个示例中，资源侦听窗包括第二资源侦听窗，终端设备侦听第二资源侦听窗内的第一侧行控制信息和第二侧行控制信息。其中，第一资源侦听窗和第二资源侦听窗是两个不同的资源侦听窗。有关第一资源侦听窗和第二资源侦听窗的介绍说明，可参见上一段落中的描述，此处不再赘述。
可选地，终端设备侦听资源侦听窗内的第一侧行控制信息和第二侧行控制信息。示例性地，该资源侦听窗从n-T 00到n-T proc,0(不包括n-T proc,0)，T 00为1100或100毫秒，T proc,0参照上文介绍。
可选地，第一排除步骤在第二排除步骤之前执行，或者，第一排除步骤在第二排除步骤之后执行。
在一些实施例中，资源排除步骤还包括第三排除步骤，第三排除步骤用于根据资源侦听窗内的未侦听时间单元进行资源排除。
可选地，在资源侦听窗的数量为一个的情况下，第三排除步骤即用于根据这一个资源侦听窗内的未侦听时间单元进行资源排除。例如，在资源侦听窗为第一资源侦听窗的情况下，第三排除步骤用于根据该第一资源侦听窗内的未侦听时间单元进行资源排除。又例如，在资源侦听窗为第二资源侦听窗的情况下，第三排除步骤用于根据该第二资源侦听窗内的未侦听时间单元进行资源排除。
可选地，在资源侦听窗的数量为两个的情况下，如资源侦听窗包括上文介绍的第一资源侦听窗和第二资源侦听窗，第三排除步骤用于根据该第一资源侦听窗内的未侦听时间单元以及第二资源侦听窗内的未侦听时间单元进行资源排除，也就是说根据第一资源侦听窗和第二资源侦听窗的并集中的未侦听时间单元进行资源排除；或者，第三排除步骤用于仅根据第一资源侦听窗内的未侦听时间单元进行资源排除；或者，第三排除步骤用于仅根据第二资源侦听窗内的未侦听时间单元进行资源排除。
在一示例性实施例中，终端设备在确定资源选择窗和资源侦听窗之后，执行如下步骤(1)～(5)所述的资源排除过程：
(1)终端设备将资源选择窗内全部的可用资源初始化为资源集合A，记资源集合A中任意一个资源为R(x,y)，x和y分别表示资源的频域位置和时域位置，记资源集合A中初始的资源数目为M total；
(2)终端设备根据资源侦听窗内的未侦听时间单元进行资源排除，也即终端设备执行第三排除步骤；
(3)终端设备根据资源侦听窗内侦听到的第一侧行控制信息进行资源排除，也即终端设备执行第一排除步骤；
(4)终端设备根据资源侦听窗内侦听到的第二侧行控制信息进行资源排除，也即终端设备执行第二排除步骤；
(5)若资源集合A中剩余资源数目小于M total*X，则抬升RSRP阈值3dB，重新执行步骤(1)，X由网络配置或预配置。
经过上述资源排除过程后的资源集合A，即步骤(5)之后的资源集合A为第一资源集合。
可选地，终端设备可以不执行步骤(2)。可选地，终端设备执行步骤(2)后若资源集合A中剩余资源数目小于M total*X，则将资源集合A初始化为执行步骤(2)之前的资源集合A，再执行后续步骤。
可选地，终端设备执行步骤(2)，(3)，(4)的顺序可以调整。如先执行步骤(2)，然后执行步骤(3)，再执行步骤(4)；或者，先执行步骤(2)，然后执行步骤(4)，再执行步骤(3)。
可选地，第三排除步骤包括：根据第一资源预留周期集合和/或第二资源预留周期集合中的资源预留周期，以及未侦听时间单元，确定未侦听时间单元对应的Q3个时间单元，Q3为正整数；若Q3个时间单元与资源集合中的目标资源或与目标资源对应的周期性资源重叠，则从资源集合中排除目标资源。
例如，目标资源为资源R(x,y)，x和y分别指示资源的频域位置和时域位置，对于上述步骤(2)，终端设备根据第一资源预留周期集合和/或第二资源预留周期集合中的每一种资源预留周期以及未侦听时间单元确定对应的Q3个时间单元，若该Q3个时间单元与R(x,y)或与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)。
可选地，第一资源预留周期集合包括第一通信系统中允许的资源预留周期中的一种或多种；或者，第一资源预留周期集合包括第一通信系统中允许的资源预留周期中的一种或多种，以及第二通信系统中允许的资源预留周期中的一种或多种；其中，第一通信系统是与第一侧行控制信息对应的通信系统，第二通信系统是与第二侧行控制信息对应的通信系统。
可选地，第二资源预留周期集合包括第二通信系统中允许的资源预留周期中的一种或多种，第二通信系统是与第二侧行控制信息对应的通信系统。
在一种可能的情况中，上述第三排除步骤包括：根据第一资源预留周期集合中的资源预留周期以及未 侦听时间单元，确定未侦听时间单元对应的Q3个时间单元。其中，资源池的配置中包括一个资源预留周期集合，如第一资源预留周期集合，该第一资源预留周期集合中包括第一通信系统中允许的资源预留周期中的一种或多种。
在另一种可能的情况中，上述第三排除步骤包括：根据第一资源预留周期集合中的资源预留周期以及未侦听时间单元，确定未侦听时间单元对应的Q3个时间单元。其中，资源池的配置中包括一个资源预留周期集合，如第一资源预留周期集合，该第一资源预留周期集合中包括第一通信系统中允许的资源预留周期中的一种或多种，以及第二通信系统中允许的资源预留周期中的一种或多种。
在又一种可能的情况中，上述第三排除步骤包括：根据第一资源预留周期集合和第二资源预留周期集合中的资源预留周期以及未侦听时间单元，确定未侦听时间单元对应的Q3个时间单元。其中，资源池的配置中包括两个资源预留周期集合，如第一资源预留周期集合和第二资源预留周期集合，该第一资源预留周期集合中包括第一通信系统中允许的资源预留周期中的一种或多种，该第二资源预留周期集合中包括第二通信系统中允许的资源预留周期中的一种或多种。
示例性地，上述第一通信系统为NR系统，第二通信系统为LTE系统。
可选地，第一排除步骤包括：根据侦听到第一侧行控制信息的第一时间单元以及第一侧行控制信息中指示的资源预留周期，确定第一时间单元对应的Q1个时间单元，并假定在该Q1个时间单元内收到同样内容的第一侧行控制信息，Q1为正整数；若侦听到的和假定将收到的第一侧行控制信息指示的资源与资源集合中的目标资源或与目标资源对应的周期性资源重叠且满足第一RSRP阈值条件，则从资源集合中排除目标资源。或者，第一排除步骤包括：判断侦听到的第一侧行控制信息指示的资源是否与资源集合中的目标资源或与目标资源对应的周期性资源重叠；若重叠且满足第一RSRP阈值条件，则从资源集合中排除目标资源。
例如，目标资源为资源R(x,y)，对于上述步骤(3)，终端设备根据侦听到第一侧行控制信息的时间单元以及该第一侧行控制信息中指示的资源预留周期，确定对应的Q1个时间单元。并假定在该Q1个时间单元内将收到同样内容的第一侧行控制信息。若上述侦听到的和假定将收到的第一侧行控制信息中“Timeresourceassignment”和“Frequencyresourceassignment”指示的资源与R(x,y)或与R(x,y)对应的一系列周期性资源重叠且满足第一RSRP阈值条件，则从资源集合A中排除资源R(x,y)。或者终端设备判断侦听到的第一侧行控制信息中“Timeresourceassignment”和“Frequencyresourceassignment”指示的资源是否与R(x,y)或与R(x,y)对应的一系列周期性资源重叠，若重叠且满足第一RSRP阈值条件则从资源集合A中排除资源R(x,y)。上述满足第一RSRP阈值条件为，侦听到的第一侧行控制信息所在的PSCCH的RSRP或该PSCCH调度的PSSCH的RSRP大于第一RSRP阈值。第一RSRP阈值可以根据第一侧行控制信息中指示的优先级以及数据传输的优先级确定。
可选地，第二排除步骤包括：根据侦听到第二侧行控制信息的第二时间单元以及第二侧行控制信息中指示的资源预留周期，确定第二时间单元对应的Q2个时间单元，并假定在该Q2个时间单元内收到同样内容的第二侧行控制信息，Q2为正整数；若侦听到的和假定将收到的第二侧行控制信息指示的资源与资源集合中的目标资源或与目标资源对应的周期性资源重叠且满足第二RSRP阈值条件，则从资源集合中排除目标资源。
例如，目标资源为资源R(x,y)，对于上述步骤(4)，终端设备根据侦听到第二侧行控制信息的时间单元以及该第二侧行控制信息中指示的资源预留周期，确定对应的Q2个时间单元。并假定在该Q2个时间单元内将收到同样内容的第二侧行控制信息。若上述侦听到的和假定将收到的第二侧行控制信息中第一至第三信息域指示的资源与R(x,y)或与R(x,y)对应的一系列周期性资源重叠且满足第二RSRP阈值条件，则从资源集合A中排除资源R(x,y)。上述满足第二RSRP阈值条件为，侦听到的第二侧行控制信息调度的PSSCH的RSRP大于第二RSRP阈值。第二RSRP阈值可以根据第二侧行控制信息中指示的优先级以及数据传输的优先级确定。另外，上述第一信息域是指第二侧行控制信息中的Frequency resource location of the initial transmission and retransmission(即初传和重传的频域资源位置指示)，第二信息域是指第二侧行控制信息中的Time gap between initial transmission and retransmission(即初传与重传间的时间间隔)，第三信息域是指第二侧行控制信息中的Retransmission index(即重传索引)。

可选地，针对第一排除步骤和第二排除步骤配置不同的RSRP阈值表。例如，通过网络配置或预配置可以针对步骤(3)和步骤(4)配置不同的RSRP阈值表，记为第一和第二RSRP阈值表，第一RSRP阈 值根据第一侧行控制信息指示的优先级和数据传输的优先级查第一RSRP阈值表确定。同理，第二RSRP阈值根据第二侧行控制信息指示的优先级和数据传输的优先级查第二RSRP阈值表确定。相应的，抬升RSRP阈值3dB是指对第一RSRP阈值表和第二RSRP阈值表中各种优先级组合对应的RSRP阈值均抬升3dB。
可选地，上文所述的数据传输的优先级，可以是终端设备的待传输数据(或者说待发送数据)的优先级，也可以是终端设备正在传输的数据(或者说正在发送的数据)的优先级。
另外，在本申请实施例中提及的“时间单元”，可以是时隙，也可以是子帧，或者是其他时间单元，本申请对此不作限定。对于本文中其他地方提及的“时间单元”，均可参考此解释，将不作重复赘述。
下面，针对条件2进行介绍说明。
在一些实施例中，第二资源为第一资源；或者，第二资源为包括第一资源在内的，与第一资源频域位置相同，时域位置间隔的一系列资源。可选地，时域位置间隔根据终端设备的资源预留周期确定。

在一些实施例中，若第二资源与根据第一侧行控制信息确定的资源重叠，则满足RSRP阈值条件包括：第一侧行控制信息对应的PSCCH或该PSCCH调度的PSSCH的SL-RSRP大于或等于第一RSRP阈值，第一RSRP阈值根据第一侧行控制信息指示的优先级和数据传输的优先级确定。当针对第一排除步骤和第二排除步骤(也即上文介绍的资源排除过程中的步骤(3)和(4))配置相同的RSRP阈值表(如第一RSRP阈值表)时，第一RSRP阈值通过第一侧行控制信息指示的优先级和终端设备数据传输的优先级查第一RSRP阈值表确定。当针对第一排除步骤和第二排除步骤(也即上文介绍的资源排除过程中的步骤(3)和(4))配置不同的RSRP阈值表(如第一与第二RSRP阈值表)时，第一RSRP阈值通过第一侧行控制信息指示的优先级和终端设备数据传输的优先级查第一RSRP阈值表确定。第一RSRP阈值表为，终端设备最后一次执行步骤(1)-(5)所使用的第一RSRP阈值表。例如，当多次执行步骤(1)-(5)时，并多次抬升第一RSRP阈值表中的阈值时，该第一RSRP阈值表为最后一次抬升后的第一RSRP阈值表。
在一些实施例中，若第二资源与根据第二侧行控制信息确定的资源重叠，则满足RSRP阈值条件包括：第二侧行控制信息调度的PSSCH的SL-RSRP大于或等于第二RSRP阈值，第二RSRP阈值根据第二侧行控制信息指示的优先级和数据传输的优先级确定。当针对第一排除步骤和第二排除步骤(也即上文介绍的资源排除过程中的步骤(3)和(4))配置相同的RSRP阈值表(如第一RSRP阈值表)时，第二RSRP阈值通过第二侧行控制信息指示的优先级和终端设备数据传输的优先级查第一RSRP阈值表确定。第一RSRP阈值表为，终端设备最后一次执行步骤(1)-(5)所使用的第一RSRP阈值表。例如，当多次执行步骤(1)-(5)时，并多次抬升第一RSRP阈值表中的阈值时，该第一RSRP阈值表为最后一次抬升后的 第一RSRP阈值表。当针对第一排除步骤和第二排除步骤(也即上文介绍的资源排除过程中的步骤(3)和(4))配置不同的RSRP阈值表(如第一与第二RSRP阈值表)时，第二RSRP阈值通过第二侧行控制信息指示的优先级和终端设备数据传输的优先级查第二RSRP阈值表确定。第二RSRP阈值表为，终端设备最后一次执行步骤(1)-(5)所使用的第二RSRP阈值表。例如，当多次执行步骤(1)-(5)时，并多次抬升第二RSRP阈值表中的阈值时，该第二RSRP阈值表为最后一次抬升后的第二RSRP阈值表。
可选地，上文所述的数据传输的优先级，可以是终端设备的待传输数据(或者说待发送数据)的优先级，也可以是终端设备正在传输的数据(或者说正在发送的数据)的优先级。
下面，针对条件3进行介绍说明。
在一些实施例中，第一侧行控制信息或第二侧行控制信息指示的优先级高于数据传输的优先级和/或高于优先级阈值，包括：
若满足第一子条件的侧行控制信息为第一侧行控制信息，则满足第一子条件的第一侧行控制信息指示的优先级高于数据传输的优先级；或者，满足第一子条件的第一侧行控制信息指示的优先级高于数据传输的优先级且高于第一优先级阈值；
或者，
若满足第一子条件的侧行控制信息为第二侧行控制信息，则满足第一子条件的第二侧行控制信息指示的优先级高于数据传输的优先级；或者，满足第一子条件的第二侧行控制信息指示的优先级高于数据传输的优先级且高于第二优先级阈值；
其中，第一子条件为：第二资源与根据侧行控制信息确定的资源重叠且满足RSRP阈值条件。也就是说，第一子条件为上文介绍的条件2。
可选地，第一优先级阈值记为U，该第一优先级阈值U由网络配置，或预配置，或为标准规定的预设值，或取决于终端设备的实现。可选地，第一优先级阈值U为资源池的配置参数，或者说第一优先级阈值U配置在资源池内。
可选地，第二优先级阈值记为Z，该第二优先级阈值Z由网络配置，或预配置，或为标准规定的预设值，或取决于终端设备的实现。可选地，第二优先级阈值Z为资源池的配置参数，或者说第二优先级阈值Z配置在资源池内。
示例性地，无论满足第一子条件(也即条件2)的是第一侧行控制信息还是第二侧行控制信息，该侧行控制信息指示的优先级高于数据传输的优先级则为满足此条件3。
示例性地，第一优先级阈值和第二优先级阈值相同，即U和Z为同一参数。在这种情况下，无论满足第一子条件(也即条件2)的是第一侧行控制信息还是第二侧行控制信息，该侧行控制信息指示的优先级需高于阈值U且高于数据传输的优先级则为满足此条件3。
示例性地，第一优先级阈值和第二优先级阈值不同，即U和Z为不同参数。在这种情况下，若满足第一子条件(也即条件2)的是第一侧行控制信息，则该第一侧行控制信息指示的优先级需高于阈值U且高于数据传输的优先级则为满足此条件3；若满足第一子条件(也即条件2)的是第二侧行控制信息，则该第二侧行控制信息指示的优先级需高于阈值Z且高于数据传输的优先级为满足此条件3。
可选地，上文所述的数据传输的优先级，可以是终端设备的待传输数据(或者说待发送数据)的优先级，也可以是终端设备正在传输的数据(或者说正在发送的数据)的优先级。
另外，以优先级数值来表示优先级，如果优先级数值越大，代表优先级越高，那么上述侧行控制信息指示的优先级高于数据传输的优先级和/或高于优先级阈值，是指侧行控制信息指示的优先级数值大于数据传输的优先级数值和/或大于优先级阈值；如果优先级数值越小，代表优先级越高，那么上述侧行控制信息指示的优先级高于数据传输的优先级和/或高于优先级阈值，是指侧行控制信息指示的优先级数值小于数据传输的优先级数值和/或小于优先级阈值。对于本申请中其他关于优先级高低的叙述，均可按照此解释。
在一示例性实施例中，对于Re-evaluation(重评估)场景，本申请实施例提供一资源重选方法如下：
在第一资源满足第一条件的情况下，终端设备重选该第一资源；其中，第一条件包括：第一资源不在第一资源集合内，第一资源集合根据第一侧行控制信息和第二侧行控制信息确定，第一侧行控制信息和第二侧行控制信息是两个不同的侧行控制信息。
在此实施例中，对于Re-evaluation(重评估)场景，第一条件包括条件1。若第一资源满足该条件1，则终端设备重选该第一资源。
示例性地，如图10所示，从终端设备内部模块的角度描述上述步骤。终端设备包括第一模块和第二模块，该第一模块和第二模块是两个不同的功能模块。例如，第一模块为NR模块，第二模块为LTE模块。可选地，LTE模块侦听第二资源侦听窗内的第二侧行控制信息。LTE模块向NR模块发送第一信息，该第 一信息包括侦听到的第二侧行控制信息。可选地，第一信息还包括以下至少之一：侦听到的第二侧行控制信息对应的时间单元(如子帧或时隙)、侦听到的第二侧行控制信息调度的PSSCH的RSRP、第二资源预留周期集合、可能属于资源池的子帧或时隙集合、Pstep(用于第二通信系统中资源预留周期到逻辑时隙的转化，Pstep可以根据TDD(Time Division Duplexing，时分双工)配置确定)、TDD配置(包括上下行配置，如上行子帧与下行子帧的比例)、侦听到的第二侧行控制信息的资源池频域资源配置(如资源池频域起点、资源池内子信道宽度、资源池内子信道数目等)。NR模块侦听第一资源侦听窗内的第一侧行控制信息，确定资源选择窗并执行上文介绍的步骤(1)-(5)确定第一资源集合，在步骤(4)中利用LTE模块提供的第一信息进行资源排除。针对NR模块已经选择且未通过发送第一侧行控制信息指示的第一资源，若该第一资源不在第一资源集合内，NR模块在第一资源集合内重选该第一资源。
示例性地，如图7所示，资源x、y、z、u、v是终端设备在时隙n已经选择的时频资源，资源y位于时隙m。对于终端设备即将在资源y发送第一侧行控制信息进行首次指示的资源z和u(资源y之前已经被资源x中的第一侧行控制信息指示)。终端设备至少在时隙m-T 3确定资源选择窗10与资源侦听窗20，并执行上述步骤(1)-(5)进行资源排除，得到第一资源集合。如果资源z和/或u不在第一资源集合中，则终端设备执行上述Step 2重选资源z和u中不在第一资源集合中的时频资源，取决于终端设备实现，终端设备也可以重选任何已经选择但未通过发送第一侧行控制信息指示的资源，例如资源z、u和v中的任意一个或多个资源。上述T 3等于T proc,1。
在一示例性实施例中，对于Pre-emption(资源抢占)场景，本申请实施例提供一资源重选方法如下：
在第一资源满足第一条件的情况下，终端设备重选该第一资源；
其中，第一条件包括：
第一资源不在第一资源集合内，第一资源集合根据第一侧行控制信息和第二侧行控制信息确定(条件1)；
第二资源与根据第一侧行控制信息确定的资源重叠，且满足RSRP阈值条件，第二资源是根据第一资源确定的资源(条件2)；
第一侧行控制信息指示的优先级高于数据传输的优先级和/或高于优先级阈值(条件3)；
其中，第一侧行控制信息和第二侧行控制信息是两个不同的侧行控制信息。
在此实施例中，对于Pre-emption(资源抢占)场景，第一条件包括条件1、条件2和条件3。若第一资源满足上述3个条件，则终端设备重选该第一资源。
示例性地，如图11所示，从终端设备内部模块的角度描述上述步骤。终端设备包括第一模块和第二模块，该第一模块和第二模块是两个不同的功能模块。例如，第一模块为NR模块，第二模块为LTE模块。可选地，LTE模块侦听第二资源侦听窗内的第二侧行控制信息。LTE模块向NR模块发送第一信息，该第一信息包括侦听到的第二侧行控制信息。可选地，第一信息还包括以下至少之一：侦听到的第二侧行控制信息对应的时间单元(如子帧或时隙)、侦听到的第二侧行控制信息调度的PSSCH的RSRP、第二资源预留周期集合、可能属于资源池的子帧或时隙集合、Pstep(用于第二通信系统中资源预留周期到逻辑时隙的转化，Pstep可以根据TDD(Time Division Duplexing，时分双工)配置确定)、TDD配置(包括上下行配置，如上行子帧与下行子帧的比例)、侦听到的第二侧行控制信息的资源池频域资源配置(如资源池频域起点、资源池内子信道宽度、资源池内子信道数目等)。NR模块侦听第一资源侦听窗内的第一侧行控制信息，确定资源选择窗并执行上文介绍的步骤(1)-(5)确定第一资源集合，在步骤(4)中利用LTE模块提供的第一信息进行资源排除。针对NR模块已经选择且已通过发送第一侧行控制信息指示的第一资源，若该第一资源满足第一条件，则NR模块在第一资源集合内重选该第一资源。上述第一条件包括：第一资源不在第一资源集合内，第二资源与根据第一侧行控制信息确定的资源重叠且满足RSRP阈值条件，第一侧行控制信息指示的优先级高于数据传输的优先级和/或高于优先级阈值。其中，第二资源是根据第一资源确定的。可选地，第二资源为第一资源，或者第二资源为包括第一资源在内的，与第一资源频域位置相同，时域位置间隔的一系列资源。
示例性地，如图12所示，资源w、x、y、z、v是终端设备在时隙n已经选择的时频资源，资源x位于时隙m。对于终端设备即将在资源x上发送第一侧行控制信息指示的且已经被终端设备之前发送的第一侧行控制信息指示的资源x。终端设备至少在时隙m-T 3确定资源选择窗10与资源侦听窗20，并执行上述步骤(1)-(5)对资源选择窗10内的资源进行资源排除，确定第一资源集合。如果资源x满足第一条件，即满足：资源x不在第一资源集合内，资源x所对应的资源与根据第一侧行控制信息确定的资源重叠且满足RSRP阈值条件，第一侧行控制信息指示的优先级高于数据传输的优先级和/或高于优先级阈值。则终端设备在第一资源集合中重选资源x。此外，当触发资源重选后，取决于终端设备实现，终端设备可以重选任何已选择但未通过发送第一侧行控制信息指示的资源，比如资源y，z和v中的任意一个或多个。上述 T 3等于T proc,1。上述资源x所对应的资源为资源x，或者为包括资源x在内的与该资源x频域位置相同、时域位置间隔的一系列资源。

其中，第一侧行控制信息和第二侧行控制信息是两个不同的侧行控制信息。
在此实施例中，对于Pre-emption(资源抢占)场景，第一条件包括条件1、条件2和条件3。若第一资源满足上述3个条件，则终端设备重选该第一资源。
示例性地，如图13所示，从终端设备内部模块的角度描述上述步骤。终端设备包括第一模块和第二模块，该第一模块和第二模块是两个不同的功能模块。例如，第一模块为NR模块，第二模块为LTE模块。可选地，LTE模块侦听第二资源侦听窗内的第二侧行控制信息。LTE模块向NR模块发送第一信息，该第一信息包括侦听到的第二侧行控制信息。可选地，第一信息还包括以下至少之一：侦听到的第二侧行控制信息对应的时间单元(如子帧或时隙)、侦听到的第二侧行控制信息调度的PSSCH的RSRP、第二资源预留周期集合、可能属于资源池的子帧或时隙集合、Pstep(用于第二通信系统中资源预留周期到逻辑时隙的转化，Pstep可以根据TDD(Time Division Duplexing，时分双工)配置确定)、TDD配置(包括上下行配置，如上行子帧与下行子帧的比例)、侦听到的第二侧行控制信息的资源池频域资源配置(如资源池频域起点、资源池内子信道宽度、资源池内子信道数目等)。NR模块侦听第一资源侦听窗内的第一侧行控制信息，确定资源选择窗并执行上文介绍的步骤(1)-(5)确定第一资源集合，在步骤(4)中利用LTE模块提供的第一信息进行资源排除。针对NR模块已经选择且已通过发送第一侧行控制信息指示的第一资源，若该第一资源满足第一条件，则NR模块在第一资源集合内重选该第一资源。上述第一条件包括：第一资源不在第一资源集合内，第二资源与根据第一侧行控制信息或第二侧行控制信息确定的资源重叠且满足RSRP阈值条件，第一侧行控制信息或第二侧行控制信息指示的优先级高于数据传输的优先级和/或高于优先级阈值。其中，第二资源是根据第一资源确定的。可选地，第二资源为第一资源，或者第二资源为包括第一资源在内的，与第一资源频域位置相同，时域位置间隔的一系列资源。
示例性地，如图12所示，资源w、x、y、z、v是终端设备在时隙n已经选择的时频资源，资源x位于时隙m。对于终端设备即将在资源x上发送第一侧行控制信息指示的且已经被终端设备之前发送的第一侧行控制信息指示的资源x。终端设备至少在时隙m-T 3确定资源选择窗10与资源侦听窗20，并执行上述步骤(1)-(5)对资源选择窗10内的资源进行资源排除，确定第一资源集合。如果资源x满足第一条件，即满足：资源x不在第一资源集合内，资源x所对应的资源与根据第一侧行控制信息或第二侧行控制信息确定的资源重叠且满足RSRP阈值条件，第一侧行控制信息或第二侧行控制信息指示的优先级高于数据传输的优先级和/或高于优先级阈值。则终端设备在第一资源集合中重选资源x。此外，当触发资源重选后，取决于终端设备实现，终端设备可以重选任何已选择但未通过发送第一侧行控制信息指示的资源，比如资源y，z和v中的任意一个或多个。上述T 3等于T proc,1。上述资源x所对应的资源为资源x，或者为包括资源x在内的与该资源x频域位置相同、时域位置间隔的一系列资源。
