为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。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。
图1是本申请实施例适用的一种通信系统的示意图。车载终端(车载终端121和车载终端122)的传输资源是由基站110分配的，车载终端根据基站110分配的资源在侧行链路上进行数据的发送。具体地，基站110可以为终端分配单次传输的资源，也可以为终端分配半静态传输的资源。
图2是本申请实施例适用的另一种通信系统的示意图。车载终端(车载终端131和车载终端132)在侧行链路的资源上自主选取传输资源进行数据传输。可选地，车载终端可以随机选取传输资源，或者通过侦听的方式选取传输资源。
需要说明的是，车联网系统采用终端到终端直接通信的方式，因此具有更高的频谱效率以及更低的传输时延。在3GPP定义了两种传输模式，分别记为：第一模式(sidelink resource allocation mode 1)和第二模式(sidelink resource allocation mode 2)。
第一模式：终端的传输资源是由基站分配的，终端根据基站分配的资源在侧行链路上进行数据的发送；基站可以为终端分配单次传输的资源，也可以为终端分配半静态传输的资源。如图1所示，终端位于网络覆盖范围内，网络为终端分配侧行传输使用的传输资源。
第二模式：终端在资源池中选取一个资源进行数据的传输。如图2所示，终端位于小区覆盖范围外，终端在预配置的资源池中自主选取传输资源进行侧行传输；或者，终端在网络配置的资源池中自主选取传输资源进行侧行传输。
为便于理解本申请实施例的技术方案，以下对本申请相关的术语进行说明。
临近业务(Proximity-based Services，ProSe)：设备到设备的通信，主要针对公共安全类的业务。
在ProSe中，通过配置资源池在时域上的位置，例如资源池在时域上非连续，达到终端设备在侧行链路上非连续发送/接收数据，从而达到省电的效果。
车联网(V2X)：车联网系统主要面向相对高速移动的车车、车人通信的业务；在V2X中，由于车载系统具有持续的供电，因此功率效率不是主要问题，而数据传输的时延是主要问题，因此在系统设计上要求终端设备进行连续的发送和接收。
可穿戴设备(FeD2D)：对应可穿戴设备通过手机接入网络的场景，其主要面向是低移动速度以及低功率接入的场景。
在FeD2D中，基站可以通过一个中继(relay)终端去配置远端(remote)终端的非连续接收(Discontinuous Reception，DRX)参数。
多载波：在长期演进(Long Term Evolution-Vehicle to Everything，LTE V2X)中，引入了多载波机制，具体地，多载波机制体可以支持数据包分割，用多个载波传输数据包，以提升数据传输率；数据包复制，将一个相同的数据包复制两份，用两个载波发送，以提升传输可靠性；以及接收端的多载波接收增强。具体地，针对数据包复制：V2X侧链通信支持侧链分组复制，并在终端设备的分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层执行。对于用于传输的侧链路分组复制，PDCP协议数据单元(Protocol Data Unit，PDU)在PDCP实体处被复制。同一PDCP实体的复制PDCP PDU被提交给两个不同的无线链路控制(Radio Link Control，RLC)实体并分别关联到两个不同的侧链逻辑信道。同一PDCP实体的复制PDCP PDU只允许在不同的侧链载波上传输。终端设备可以基于(预)配置来激活或停用侧链分组复制。侧链数据包复制不适用于具有传输配置文件的传输。支持侧链数据包复制的单包可靠性(ProSe Per-Packet Reliability，PPPR)值可以通过PPPR阈值(预)配置。对于终端设备自主的资源选择和调度的资源分配，终端设备应对具有配置的PPPR值的数据执行侧链分组复制，直到为这些PPPR值取消分组复制配置为止。对于调度的资源分配，终端设备通过侧行缓存状态报告(Buffer Status Report，BSR)报告与一个或多个PPPR值相关联的数据量以及数据所属的目的地。PPPR值到逻辑信道组的映射可以由eNB配置，并且PPPR值由包括在侧行BSR中的相关联的逻辑信道组标识(Identity，ID)反映。一个或多个PPPR值的列表可以由一个无线资源控制(Radio Resource Control，RRC)连接的终端设备在侧行终端信息中报告。
新无线-车辆到其他设备(New Radio-Vehicle to Everything，NR-V2X)在LTE V2X的基础上，不局限于广播场景，而是进一步拓展到了单播和组播的场景。
类似于LTE V2X，NR V2X也会定义上述模式1(即上述第一模式)和模式2(即上述第二模式)两种资源授权模式；更进一步，用户可能处在一个混合的模式下，即既可以使用模式1进行资源的获取，又同时可以使用模式2进行资源的获取。该资源获取通过侧行链路授权的方式指示，即侧行链路授权指示相应的物理侧行控制信道(Physical Sidelink Control Channel，PSCCH)与物理侧行共享信道(Physical Sidelink Shared Channel，PSSCH)资源的时频位置。
不同于LTE V2X，除了无反馈的、终端设备自主发起的混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)重传，NR V2X引入了基于反馈的HARQ重传，不限于单播通信，也包括组播通信；与LTE V2X相同，在NR V2X中，由于车载系统具有持续的供电，因此功率效率不是主要问题，而数据传输的时延是主要问题，因此在系统设计上要求终端设备进行连续的发送和接收。
与LTE V2X相同，在NR V2X中，由于车载系统具有持续的供电，因此功率效率不是主要问题，而数据传输的时延是主要问题，因此在系统设计上要求终端设备进行连续的发送和接收。
在侧行通信中，终端会在以下场景中触发侧行链路无线资源控制(Radio Resource Control，RRC)重配过程：
在单播通信中释放侧行链路数据承载；
在单播通信中建立侧行链路数据承载；
在单播通信中修改侧行链路数据承载的相关配置；
在终端到网络中继场景中，释放层二中继终端与远端终端之间的PC5中继RLC信道；
在终端到网络中继场景中，建立层二中继终端与远端终端之间的PC5中继RLC信道；
在终端到网络中继场景中，修改层二中继终端与远端终端之间的PC5中继RLC信道相关的配置参数；
NR侧行链路测量上报相关参数的重配置；
侧行链路信道状态信息(Channel State Information，CSI)参考信号资源与CSI上报延迟边界的重配；
对于对端终端侧行链路非连续接收(Discontinuous Reception，DRX)的重配。
为便于更好的理解本申请实施例，对本申请相关的终端到网络中继进行说明。
在NR系统中，针对终端到网络的中继，将场景限制在了同基站下的远端终端在侧行中继链路(即远端终端通过中继终端接入网络的链路)与Uu链路(即远端终端直接接入网络的链路)之间进行切换。在NR演进中，为以下场景指定增强单跳层2(Layer-2，L2)终端到网络(UE to Network，U2N)中继服务连续性的机制，新增加了以下四种新的场景：
gNB外(Inter-gNB)非直接到直接(indirect-to-direct)路径切换(path switching)(例如，“远端终端<->中继终端A<->gNB X”切换至“远端终端<->gNB Y”)；
gNB外(Inter-gNB)直接到非直接(indirect-to-direct)路径切换(path switching)(例如，“远端终端<->gNB X”切换至“远端终端<->中继终端A<->gNB Y”)；
gNB内(Intra-gNB)非直接到非直接(indirect-to-indirect)路径切换(path switching)(例如，“远端终端<->中继终端A<->gNB X”切换至“远端终端<->中继终端B<->gNB X”)；
gNB外(Inter-gNB)非直接到非直接(indirect-to-indirect)路径切换(path switching)(例如，“远端终端<->中继终端A<->gNB X”切换至“远端终端<->中继终端B<->gNB Y”)。
并且，针对远端终端在侧行中继链路(即远端终端通过中继终端接入网络的链路)与Uu链路(即远端终端直接接入网络的链路)之间进行切换，引入了测量上报事件，如事件X1、事件X2、事件Y1和事件Y2。
事件X1
在事件X1中，L2 U2N中服务中继终端的测量结果变得比第一阈值差，NR小区的测量结果变得比第二阈值好。
事件X1的准入条件：满足以下条件X1-1和条件X1-2；
事件X1的离开条件：满足以下条件X1-3和/或条件X1-4。
不等式X1-1(准入条件X1-1)：Mr+Hys<第一阈值。
不等式X1-2(准入条件X1-2)：Mn+Ofn+Ocn–Hys>第二阈值。
不等式X1-3(离开条件X1-3)：Mr–Hys>第一阈值。
不等式X1-4(离开条件X1-4)：Mn+Ofn+Ocn+Hys<第二阈值。
