具体实施方式
为了便于理解，首先介绍本公开涉及的术语。
1、侧行链路(sidelink，SL)
侧行链路(sidelink，SL)是为了支持车对外界的信息交换(vehicle to everything，V2X)设备间直接通信而引入的新链路类型。侧行链路的设计和增强具体内容包括研究侧行链路上的单播、组播和广播传输，具体包括基于新空口(new radio，NR)的侧行链路的物理层架构和流程、侧行链路的同步机制、链路的资源分配模式、侧行链路的层2/层3协议等。
2、子载波间隔(subcarrier spacing，SCS)
载波是通信系统里的频域资源概念，子载波可以认为是可独立调制的一小段频域资源。一个子信道有一个或者多个子载波，比如100MHz带宽里，假设15KHz是一个子载波，则此子信道可以包含多个子载波。
3、无线资源控制(radio resource control，RRC)
无线资源控制(radio resource control，RRC)，又称为无线资源管理或者无线资源分配，是指通过一定的策略和手段进行无线资源管理、控制和调度，在满足服务质量的要求下，尽可能地充分利用有限的无线网络资源，确保到达规划的覆盖区域，尽可能地提高业务容量和资源利用率。
请参见图1，图1为本公开实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个网络设备和一个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本公开实施例的限定，实际应用中可以包括两个或两个以上的网络设备，两个或两个以上的终端设备。图1所示的通信系统以包括一个网络设备11和一个终端设备12为例。

本公开实施例中的网络设备11是网络侧的一种用于发射或接收信号的实体。例如，网络设备101可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本公开的实施例对网络设备所采用的具体技术和具体设备形态不做限定。本公开实施例提供的网络设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本公开实施例中的终端设备12是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本公开的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
可以理解的是，本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本公开所提供的一种新空口和新空口侧行链路切换的方法及其装置进行详细地介绍。
请参见图2，图2是本公开实施例提供的一种新空口和新空口侧行链路切换的方法的流程示意图，该方法由网络设备执行。如图2所示，该方法可以包括但不限于如下步骤：
步骤201，接收第一指示信息，其中，第一指示信息用于指示终端设备的切换能力。
需要说明的是，在不同的新空口NR与新空口NR侧行链路SL的切换场景中，具体的切换时间可能有所差异。比如，可以通过关闭切换前的射频功率，再打开切换后的射频功率(即on-off-on方式)，实现NR和NR SL切换。而NR和NR SL的射频配置时间，即从关断功率到打开功率(相反的从打开功率到关断功率)所需要的时间，都为10微秒(μs)。因此，在1条射频链路上，NR与NR SL同频点进行切换，所需要的最长时间可以为20微秒(μs)。
或者，如果NR和NR SL在切换前后只有功率发生改变，其他参数部分，比如子载波间隔(subcarrier spacing，SCS)，带宽部分(bandwidth part，BWP)等均没有改变，则可以直接打开切换后的射频功率(即on-on方式)，实现NR和NR SL切换。因此，在1条射频链路上，NR和NR SL切换前后只有功率发生改变的情况下，NR和NR SL在切换所需的最长时间为10微秒(μs)。
或者，如果终端设备配置了两条完整的射频链路，则可以通过预先在一条链路上做好切换前的准备，实现两条链路间的直接切换，从而可以进一步节省切换时间，实际的切换时间大约在0.5us左右。
本公开中，切换能力，为终端设备根据其具备的射频切换链路数量确定的。举例来说，如果终端设备支持两条链路切换，则终端设备的切换能力可以为：具备两条射频切换链路，如果终端设备支持一条链路切换，则终端设备的切换能力可以为：具备一条射频切换链路。
相应的，第一指示信息可以为指示终端具备两条射频切换链路，或者具备一条射频切换链路等。
本公开中，网络设备在接收到第一指示信息后，即可确定终端设备的切换能力。
步骤202，根据终端设备的切换能力，确定终端设备进行新空口NR和新空口NR侧行链路SL切换的切换时间。
本公开中，考虑到由于终端设备在切换链路的过程中，不能进行其他任务的处理，因此，网络设备可以根据不同终端设备的切换能力，灵活的配置切换时间。从而避免在终端设备能够进行快速切换的情况下，因配置过长的切换时间，导致时频域资源的浪费的现象，或者是终端设备需要较长切换时间的情况下，因配置了过短的切换时间，导致部分信息接收失败的现象。
可选的，在终端设备的切换能力为具备一条射频切换链路的情况下，网络设备可以确定终端设备进行新空口NR和新空口NR侧行链路SL切换的切换时间较长。在终端设备的切换能力为具备两条射频切换链路的情况下，网络设备可以确定终端设备进行新空口NR和新空口NR侧行链路SL切换的切换 时间较短。之后，网络设备，即可根据终端设备进行新空口NR和新空口NR侧行链路SL切换的实际所需时间，合理的配置用于终端设备进行切换的时间。
本公开中，网络设备首先接收终端设备发送的用于指示其切换能力的第一指示信息，之后再根据终端设备的切换能力，确定终端设备进行新空口NR和新空口NR侧行链路SL切换的切换时间。由此，既保证了时频域资源可以被有效利用，又避免了在终端设备切换过程中出现信息接收失败的情况。
请参见图3，图3是本公开实施例提供的另一种新空口和新空口侧行链路切换的方法流程示意图。如图3所示，该方法可以由网络设备执行，该方法可以包括但不限于如下步骤：
步骤301，接收无线资源控制RRC信令。
本公开中，终端设备可以通过RRC信令中的预设比特的取值，标识第一指示信息。比如，在RRC信令中用一个比特位标识终端设备的切换能力时，当终端设备不具备两条链路切换的能力，即当只具备一条链路切换的能力时，可以设置比特值为0，当终端设备具备两条链路切换的能力时，可以设置比特值为1。
步骤302，根据RRC信令中的预设比特的取值，确定第一指示信息。
本公开中，网络设备在接收到网络设备发送的RRC信令后，可以根据RRC信令中的预设的比特位的取值，确定第一指示信息。
步骤303，根据终端设备的切换能力，确定终端设备进行新空口NR和新空口NR侧行链路SL切换的切换时间。
本公开中，网络设备在确定终端设备的切换能力后，即可根据终端设备的切换能力，或者NR和NR SL分别对应的载波的属性信息，确定终端设备进行新空口NR和新空口NR侧行链路SL切换的切换时间。
其中，载波的属性信息可以包括以下至少一项：子载波间隔SCS，带宽部分BWP。可选的，载波的属性信息，还可以包括载波的位置等其他信息，本公开对此不做限定。
可选的，在终端设备的切换能力为具备两条射频切换链路的情况下，则可以确定终端设备进行NR和NR SL切换的第一切换时间，比如为0.5us、0.6us。
其中，为了尽量避免时频域资源的浪费的现象或出现信息接收失败的现象，本公开中第一切换时间可以根据终端设备具备两条射频切换链路的情况下，通过预先在一条链路上做好切换前的准备后，进行NR和NR SL切换所需的最大时间确定。
可选的，在终端设备的切换能力为具备一条射频切换链路的情况下，可以根据切换前后的NR和NR SL分别对应的载波的属性信息，确定终端设备进行NR和NR SL切换的第二切换时间。其中，第二切换时间可以根据在终端设备只具备一条射频切换链路的情况下，终端设备进行NR和NR SL进行切换所需的最大时间确定。由此，可以精确的确定终端设备进行新空口和新空口侧行链路切换的时间，从而进一步提高了时频域资源利用率。
可以理解的是，在一条射频链路上，进行NR和NR SL切换时，可以通过开关功率的方式，实现NR和NR SL切换，在两条射频链路上，进行NR和NR SL切换时，可以预先在一条链路上准备做好切换准备，所以所需要的的切换时间大幅度降低。因此，第二切换时间大于第一切换时间。
本公开中，网络设备通过接收终端设备发送的无线资源控制RRC信令，并根据RRC信令中的预设比特的取值，确定第一指示信息，然后再根据终端设备的切换能力，确定终端设备进行新空口NR和新空口NR侧行链路SL切换的切换时间。由此，既保证了时频域资源可以被有效利用，又避免了在终端设备切换过程中出现信息接收失败的情况。
请参见图4，图4是本公开实施例提供的另一种新空口和新空口侧行链路切换的方法流程示意图。如图4所示，该方法可以由网络设备执行，该方法可以包括但不限于如下步骤：
步骤401，发送第二指示信息，其中，第二指示信息用于指示终端设备上报切换能力。
其中，第二指示信息可以用比特值的方式指示终端设备上报切换能力，比如，用1标识需要上报切换能力，用0标识不需要上报切换能力。或者用文本信息的方式指示终端设备上报切换能力。本公开对此不作限制。
本公开中，网络设备，在新空口与新空口侧行链路的切换场景中，或者，在未知终端设备的切换能力的情况下，可以主动的向终端设备发送第二指示信息，以通知终端设备开始上报切换能力。
步骤402，接收第一指示信息，其中，第一指示信息用于指示终端设备的切换能力。
步骤403，响应于终端设备的切换能力为具备两条射频切换链路，确定终端设备进行NR和NR SL切换的第一切换时间。
本实施例中，步骤402-步骤403的具体实现过程，可参见本公开任一实施例的详细描述，在此不再赘述。
步骤404，响应于终端设备的切换能力为具备一条射频切换链路，根据切换前后的NR和NR SL分别对应的载波的属性信息，确定终端设备进行NR和NR SL切换的第二切换时间。
本实施例中，在终端设备的切换能力为具备一条射频切换链路的情况下，获取切换前后的NR和NR SL分别对应的载波的属性信息之后，将切换前后的NR和NR SL分别对应的载波的属性信息进行比较，如果两个载波的属性信息相同，则可以确定第二切换时间为第一数值，如果两条射频切换链路的载波的属性信息不相同，则可以确定第二切换时间为第二数值。由此，网络设备根据切换前后的NR和NR SL分别对应的载波的属性信息，进一步精确了进行新空口和新空口侧行链路切换的时间，从而进一步提高了时频域资源的利用率。
其中，在NR和NR SL分别对应的载波的属性信息相同的情况下，进行NR和NR SL切换时，只需要调整射频链路的功率即可，即此时的切换方式为on-on的方式，从而第一数值可以根据，通过on-on的方式进行切换所需要的时间确定。相应的，在NR和NR SL分别对应的载波的属性信息不相同的情况下，进行NR和NR SL切换时，需要先关闭切换前的射频功率，再打开切换后的射频功率，即此时的切换方式为on-off-on，从而第二数值可以根据，通过on-off-on的方式进行切换所需要的时间确定。因此，第一数值可以为10us，第二数值可以为20us，第二数值大于第一数值。
本公开中，网络设备向终端设备发送第二指示信息后，可以接收终端设备发送的第一指示信息，然后，响应于终端设备的切换能力为具备一条射频切换链路，根据切换前后的NR和NR SL分别对应的载波的属性信息，确定终端设备进行NR和NR SL切换的第二切换时间。由此，既保证了时频域资源可以被有效利用，又避免了在终端设备切换过程中出现信息接收失败的情况。
请参见图5，图5是本公开实施例提供的一种新空口和新空口侧行链路切换的方法的流程示意图，该方法由终端设备执行。如图5所示，该方法可以包括但不限于如下步骤：
步骤501，发送第一指示信息，其中，第一指示信息用于指示终端设备的切换能力。
需要说明的是，在不同的新空口NR与新空口NR侧行链路SL的切换场景中，具体的切换时间可能有所差异。比如，可以通过关闭切换前的射频功率，再打开切换后的射频功率(即on-off-on方式)，实现NR和NR SL切换。而NR和NR SL的射频配置时间，即从关断功率到打开功率(相反的从打开功率到关断功率)所需要的时间，都为10微秒(μs)。因此，在1条射频链路上，NR与NR SL同频点进行切换，所需要的最长时间可以为20微秒(μs)。
或者，如果NR和NR SL在切换前后只有功率发生改变，其他参数部分，比如子载波间隔(subcarrier spacing，SCS)，带宽部分(bandwidth part，BWP)等均没有改变，则可以直接打开切换后的射频功率(即on-on方式)，实现NR和NR SL切换。因此，在1条射频链路上，NR和NR SL切换前后只有功率发生改变的情况下，NR和NR SL在切换所需的最长时间为10微秒(μs)。
或者，如果终端设备配置了两条完整的射频链路，则可以通过预先在一条链路上做好切换前的准备，实现两条链路间的直接切换，从而可以进一步节省切换时间，实际的切换时间大约在0.5us左右。
本公开中，切换能力，为终端设备根据其具备的射频切换链路数量确定的。举例来说，如果终端设备支持两条链路切换，则终端设备的切换能力可以为：具备两条射频切换链路，如果终端设备支持一条链路切换，则终端设备的切换能力可以为：具备一条射频切换链路。
相应的，第一指示信息可以为指示终端具备两条射频切换链路，或者具备一条射频切换链路等。
本公开中，终端设备向网络设备发送的用于指示其切换能力的第一指示信息后，网络设备即可根据终端设备的切换能力，确定终端设备进行新空口NR和新空口NR侧行链路SL切换的切换时间。由此，既保证了时频域资源可以被有效利用，又避免了在终端设备切换过程中出现信息接收失败的情况。

步骤602，发送RRC信令。
本公开中，当终端设备完成RRC信令设置后，即可将RRC信令发送给网络设备，网络设备在接收到RRC信令后，即可根据RRC信令中的预设比特的取值，确定第一指示信息。
本公开中，终端设备在根据终端设备的切换能力，确定无线资源控制RRC信令中与第一指示信息对应的预设比特的取值后，可以将无线资源控制RRC信令发送给网络设备。网络设备在接收到RRC 信令后，即可根据RRC信令中的预设比特的取值，确定第一指示信息，然后再根据终端设备的切换能力，确定终端设备进行新空口NR和新空口NR侧行链路SL切换的切换时间。由此，既保证了时频域资源可以被有效利用，又避免了在终端设备切换过程中出现信息接收失败的情况。

其中，第二指示信息可以用比特值的方式指示终端设备上报切换能力，比如，用1标识需要上报切换能力，用0标识不需要上报切换能力。或者用文本信息的方式指示终端设备上报切换能力。本公开对此不作限制。
本公开中，网络设备，在新空口与新空口侧行链路的切换场景中，或者，在未知终端设备的切换能力的情况下，可以主动的向终端设备发送第二指示信息，以通知终端设备开始上报切换能力。
步骤702，发送第一指示信息，其中，第一指示信息用于指示终端设备的切换能力。
本实施例中，步骤702的具体实现过程，可参见本公开任一实施例的详细描述，在此不再赘述。
本公开中，终端设备接收到网络设备发送的第二指示信息后，即可向网络设备发送第一指示信息，然后，网络设备在接收到第一指示信息后，可以根据终端设备的切换能力，确定终端设备进行新空口NR和新空口NR侧行链路SL切换的切换时间。由此，既保证了时频域资源可以被有效利用，又避免了在终端设备切换过程中出现信息接收失败的情况。
