具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。针对本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例可以适用于任何终端设备到终端设备的通信框架。
例如，车辆到车辆(Vehicle to Vehicle，V2V)、车辆到其他设备(Vehicle to Everything，V2X)、终端到终端(Device to Device，D2D)等。
其中，本申请实施例中的终端可以是任何配置有物理层和媒体接入控制层的设备或装置，终端设备也可称为接入终端。例如，用户设备(User Equipment，UE)、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。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、个人数字线性处理(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线性处理设备、车载设备、可穿戴设备等等。本申请实施例以车载终端为例进行说明，但并不限于此。
可选地，在本申请的一些实施例中，本申请实施例可以适用于第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)定义了两种传输模式，分别记为：模式A和模式B。
图1是本申请实施例的模式A的示意图。图2是本申请实施例的模式B的示意图。
在图1所示的模式A中，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。
在图2所示的模式B中，车载终端(车载终端131和车载终端132)采用侦听(sensing)加预留(reservation)的传输方式，车载终端在侧行链路的资源上自主选取传输资源进行数据传输。
下面以车载终端131为例进行具体说明。
车载终端131在资源池中通过侦听的方式获取可用的传输资源集合，车载终端131从该集合中随机选取一个传输资源进行数据的传输。
由于车联网系统中的业务具有周期性特征，本申请实施例中，车载终端131还可以采用半静态传输的方式。即车载终端131获取一个传输资源后，在多个传输周期中持续的使用该传输资源，以降低资源重选以及资源冲突的概率。
车载终端131可以在本次传输的控制信息中携带预留下次传输资源的信息，使得其他终端(例如，车载终端132)可以通过检测该用户的控制信息判断这块资源是否被该用户预留和使用，达到降低资源冲突的目的。
需要说明的是，在NR V2X中，用户可能处在一个混合的模式下，即既可以使用模式A进行资源的获取，又同时可以使用模式B进行资源的获取。
在终端设备(例如车载终端131或者车载终端132)仅支持LTE侧行通信时，可以通过如下两种方式进行小区重选：
方式一，载波内配置场景，具体地，载波F1上部署了LTE网络，该LTE网络提供关于载波F1上侧行通信的配置，若终端设备希望在载波F1上进行侧行通信，终端设备将载波F1视为最高优先级载波，该终端设备优先驻留在载波F1上。
方式二，跨载波配置场景，具体地，载波F2上部署了LTE网络，该LTE网络在载波F2上提供关于载波F1上侧行通信的配置，若终端设备希望在载波F1上进行侧行通信，终端设备将载波F2视为最高优先级载波，该终端设备优先驻留在载波F2上。
需要说明的是，小区重选可以分为两个阶段：阶段一，确定驻留载波；阶段二，在驻留载波上确定目标小区进行接入。本申请实施例侧重于驻留载波的确定。
3GPP正在讨论NR V2X，终端设备可能同时支持LTE侧行通信和NR侧行通信，但是终端设备只能驻留一个载波上，因此，在终端设备既支持LTE侧行通信又支持NR侧行通信的情况下如何进行小区重选机制设计是本申请需要解决的问题。
基于上述技术问题，本申请设计了一种无线通信方法，可以在终端设备既支持LTE侧行通信又支持NR侧行通信的情况下进行小区重选。
图3是本申请实施例的无线通信方法200的示意性流程图。该方法200可以由终端设备执行。图3中所示的终端设备可以是如图1或图2所示的车载终端。
如图3所示，该方法200可以包括如下内容中的部分或者全部：
S210，终端设备根据载波属性，确定用于小区重选的多个载波的载波优先级顺序，其中，该载波属性针对至少两个网络的侧行通信。
在本申请实施例中，该载波优先级顺序可以用于小区重选中的载波选取。例如选择该载波优先级顺序中优先级最高的载波进行驻留。又例如，在该载波优先级顺序中选择能够搜索到的且排序最高的载波进行驻留。
也就是说，在本申请实施例中，该终端设备可以支持该至少两个网络的侧行通信。
可选地，该至少两个网络包括LTE网络和NR网络。当然，该至少两个网络还可以包括一些其他的网络，例如，演进的长期演进(Evolved Long Term Evolution，eLTE)、先进的长期演进(Advanced Long Term Evolution，LTE-A)，本申请对此并不限定。
可选地，针对载波内配置场景，假设该终端设备需要在载波X上进行LTE侧行通信，以及需要在载波Y和载波Z上进行NR侧行通信，且LTE网络通过载波X提供关于载波X上进行侧行通信的配置或者参数，NR网络通过载波Y提供关于载波Y上进行侧行通信的配置或者参数，NR网络通过 载波Z提供关于载波Z上进行侧行通信的配置或者参数，即该多个载波可以包括载波X、载波Y和载波Z中的部分或者全部。
可选地，针对跨载波配置场景，假设该终端设备需要在载波X上进行LTE侧行通信，以及需要在载波Y和载波Z上进行NR侧行通信，且LTE网络通过载波F1和载波F2提供关于载波X上进行侧行通信的配置或者参数，NR网络通过载波F3和F4提供关于载波Y上进行侧行通信的配置或者参数，NR网络通过载波F5提供关于载波Z上进行侧行通信的配置或者参数，即该多个载波可以包括载波X、载波Y、载波Z、载波F1、载波F2、载波F3、载波F4和载波F5中的部分或者全部。
需要说明的是，上述侧行通信的配置或者参数可以包括该载波属性。
可选地，在本申请实施例中，该载波属性包括但不限于以下中的至少一种：
载波所支持的该至少两个网络中的网络的数量，载波所支持的该至少两个网络中的网络的类型，该终端设备在所支持的网络上进行侧行通信时所使用的配置信息类型。
可选地，该配置信息类型包括预配置和网络配置。
可选地，在本申请实施例中，该终端设备需要提前获取该载波属性。例如，该终端设备根据系统广播消息获取该载波属性。
可选地，作为实施例一，假设该至少两个网络包括第一网络和第二网络，以及该多个载波包括第一载波，若终端设备在驻留到该第一载波的情况下能够进行该第一网络和/或该第二网络的侧行通信，则该终端设备确定在该多个载波中该第一载波具有最高优先级。
例如，如果只有驻留到第一载波上，终端设备才能进行LTE侧行通信和/或NR侧行通信，则确定在该多个载波中该第一载波具有最高优先级。
进一步地，在实施例一中，若该终端设备在驻留到该第一载波的情况下能够按照网络配置进行该第一网络和/或该第二网络的侧行通信，则该终端设备确定在该多个载波中该第一载波具有最高优先级。
更进一步地，在实施例一中，若该终端设备在驻留到该多个载波中除该第一载波之外的其他载波的情况下无法按照网络配置进行该第一网络和/或该第二网络的侧行通信，则该终端设备确定在该多个载波中该第一载波具有最高优先级。
也就是说，若该终端设备在驻留到该第一载波的情况下能够进行该第一网络和/或该第二网络的侧行通信，且该终端设备在驻留到该多个载波中除该第一载波之外的其他载波的情况下无法进行该第一网络和/或该第二网络的侧行通信，则该终端设备确定在该多个载波中该第一载波具有最高优先级。
或者，若该终端设备在驻留到该第一载波的情况下能够按照网络配置进行该第一网络和/或该第二网络的侧行通信，且该终端设备在驻留到该多个载波中除该第一载波之外的其他载波的情况下无法按照网络配置进行该第一网络和/或该第二网络的侧行通信，则该终端设备确定在该多个载波中该第一载波具有最高优先级。
更进一步地，在实施例一中，若该终端设备在未驻留到该第一载波的情况下仅能够按照预配置进行该第一网络和/或该第二网络的侧行通信，则该终端设备确定在该多个载波中该第一载波具有最高优先级。
也就是说，若该终端设备在驻留到该第一载波的情况下能够进行该第一网络和/或该第二网络的侧行通信，且该终端设备在未驻留到该第一载波的情况下仅能够按照预配置进行该第一网络和/或该第二网络的侧行通信，则该终端设备确定在该多个载波中该第一载波具有最高优先级。
或者，若该终端设备在驻留到该第一载波的情况下能够按照网络配置进行该第一网络和/或该第二网络的侧行通信，且该终端设备在未驻留到该第一载波的情况下仅能够按照预配置进行该第一网络和/或该第二网络的侧行通信，则该终端设备确定在该多个载波中该第一载波具有最高优先级。
更进一步地，在实施例一中，若该终端设备在驻留到该第一载波的情况下不需要按照预配置进行该第一网络和/或该第二网络的侧行通信，则该终端设备确定在该多个载波中该第一载波具有最高优先级。
也就是说，若该终端设备在驻留到该第一载波的情况下能够按照网络配置进行该第一网络和/或该第二网络的侧行通信，且不需要按照预配置进行该第一网络和/或该第二网络的侧行通信，则该终端设备确定在该多个载波中该第一载波具有最高优先级。
可选地，作为实施例二，假设该至少两个网络包括第一网络和第二网络，以及该多个载波包括第一载波和第二载波，
若该终端设备在驻留到该第一载波的情况下能够进行该第一网络和该第二网络的侧行通信，且该终端设备在驻留到该第二载波的情况下能够进行该第一网络或者该第二网络的侧行通信，该终端设备确定在该多个载波中该第一载波具有最高优先级；或者，
若该终端设备在驻留到该第一载波的情况下能够按照网络配置进行该第一网络和该第二网络的侧行通信，且该终端设备在驻留到该第二载波的情况下需要按照预配置进行该第一网络或者该第二网络的侧行通信，该终端设备确定在该多个载波中该第一载波具有最高优先级。
例如，如果只有驻留到载波A上，终端设备才能进行LTE侧行通信和NR侧行通信，而只有驻留到载波B上，终端设备才能进行LTE侧行通信或NR侧行通信，则优先选择载波A。
又例如，如果驻留到载波A上，终端设备既不需要进行预配置的LTE侧行通信也不需要进行预配置的NR侧行通信，而如果驻留到载波B上，终端设备仍需要进行预配置的LTE侧行通信或NR侧行通信，则优先选择载波A。
可选地，在实施例二中，若该终端设备未配置该第一载波或者未搜索到该第一载波，该终端设备确定优先选择该第二载波。
需要说明的是，假设载波1的优先级高于载波2，则在小区重选时终端设备优先选取载波1，终端设备优先搜索载波1，在未配置载波1或者未搜索到载波1的情况下，优先选择载波2。
进一步地，在实施例二中，该第二载波包括第一子载波和第二子载波，若该终端设备在驻留到该第一子载波的情况下需要按照预配置进行该第一网络的侧行通信，且该终端设备在驻留到该第二子载波的情况下需要按照预配置进行该第二网络的侧行通信，则该终端设备根据需要进行的侧行通信业务所属的网络进行子载波优先级确定。
具体地，若该终端设备需要进行的侧行通信业务属于该第二网络，则该终端设备确定该第一子载波的优先级大于该第二子载波的优先级；或者，若该终端设备需要进行的侧行通信业务属于该第一网络，则该终端设备确定该第二子载波的优先级大于该第一子载波的优先级。
例如，假设该第二载波为载波B，且载波B包括载波B1和载波B2，如果驻留到载波B1上，终端设备仍需要按照预配置进行LTE侧行通信，而如果驻留到载波B2上，终端设备仍需要按照预配置进行NR侧行通信，则终端设备根据当前侧行链路需要进行的业务进行优先级的确定，例如目前需要进行LTE侧行通信，则优先选择载波B2。
需要说明的是，该终端设备需要进行的侧行通信业务属于该第一网络可以理解为：该终端设备需要进行的侧行通信业务所使用的无线接入技术(Radio Access Technology，RAT)和/或载波属于该第一网络。同理，该终端设备需要进行的侧行通信业务属于该第二网络可以理解为：该终端设备需要进行的侧行通信业务所使用的RAT和/或载波属于该第二网络。
可选地，在上述实施例一和实施例二中，该第一网络为LTE网络，该第二网络为NR网络；或者，该第一网络为NR网络，该第二网络为LTE网络。
需要说明的是，上述实施例一和实施例二可以相互结合，本申请对此并不限定。
可选地，在本申请实施例中，该终端设备根据该载波优先级顺序，针对需要进行侧行通信的目标载波进行小区重选。
需要说明的是，在本申请实施例中，考虑到可能存在跨载波配置场景，即根据该载波优先级顺序，优先选择的载波不一定是进行侧行通信的载波。因此，该终端设备可以根据该载波优先级顺序，针对需要进行侧行通信的目标载波进行小区重选。
因此，在本申请实施例中，终端设备根据载波属性确定用于小区重选的多个载波的载波优先级顺序，从而可以在终端设备既支持LTE侧行通信又支持NR侧行通信的情况下可以进行小区重选。
