在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本公开，在附图中仅仅示出了与根据本公开的方案密切相关的设备结构和/或处理步骤，而省略了与本公开关系不大的其他细节。
<第一实施例>
图1示出了根据本申请的一个实施例的电子设备100的功能模块框图，如图1所示，电子设备100包括：生成单元101，被配置为生成第一信号，该第一信号用于指示第一通信设备是否在基站的覆盖范围内以及/或者第一通信设备是否执行了网络侧定位；以及通信单元102，被配置为将第一信号发送至一个或多个第二通信设备用于进行定位计算。
其中，生成单元101和通信单元102可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片、处理器。并且，应该理解，图1中所示的电子设备中的各个功能单元仅是根据其所实现的具体功能而划分的逻辑模块，而不是用于限制具体的实现方式。
电子设备100例如可以设置在第一通信设备侧或可通信地连接到第一通信设备。第一通信设备和第二通信设备例如可以为UE。示例性地，在车辆网(V2X)通信场景下，第一通信设备和第二通信设备可以为V2X中的用户设备，例如可以设置在车辆侧。
这里，还应指出，电子设备100可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备100可以工作为通信设备(比如UE)本身，并且还可以包括诸如存储器、收发器(图中未示出)等外部设备。存储器可以用于存储通信设备实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，其他通信设备、基站等等)间的通信，这里不具体限制收发器的实现形式。
此外，本文中的第一、第二等仅是为了区分的用途，并不代表任何顺序等方面的含义。
对于侧链通信，作为通信双方的通信设备可能处于不同的基站覆盖场景下。在不同的基站覆盖场景下，通信设备能够获得的与定位相关的信息不同，因此进行侧链定位的计算方案将不同。例如，当通信设备在基站覆盖范围内时，可以例如通过与基站之间的通信和测量来进行网络侧定位从而获得该通信设备的地理位置信息，这样获得的地理位置信息例如可以用作侧链通信中对方通信设备的地理位置的参考。因此，获知对方通信设备的基站覆盖状态(即，对方通信设备是否处于基站的覆盖范围内)以及/或者是否进行了网络侧定位对于确定恰当的定位计算方案以及进行高效的定位是非常有意义的。
在本实施例中，提出了第一通信设备通过第一信号来向第二通信设备指示第一通信设备的基站覆盖状态以及/或者是否进行了网络侧定位的方案。在第一信号指示第一通信设备在基站的覆盖范围内以及/或者第一通信设备执行了网络侧定位的情况下，通信单元102还被配置为在与第一信号相关联的子帧内发送第一通信设备基于网络侧定位而获得的第一定位信息。该第一定位信息例如为第一通信设备的绝对位置，具体地，例如为第一通信设备的经纬度坐标。在另一个示例中，该第一定位信息为第一通信设备的相对位置，具体地，例如为第一通信设备相对于某一参考点的相对位置，如基站的位置可作为参考点。
通信设备之间的相关信息流程如图2所示。其中，第一通信设备表示为发送UE(Tx UE)，第二通信设备表示为接收UE(Rx UE)。Tx UE基于自身的基站覆盖状态以及/或者是否执行了网络侧定位生成第一信号，并将第一信号发送给Rx UE。在第一信号指示Tx UE在基站覆盖范围内以及/或者Tx UE执行了网络侧定位的情况下，Tx UE还向Rx UE发送通过网络侧定位获得的第一定位信息。图中的虚线代表对应的第一定位信息的发送是可选的，例如，在Tx UE不在基站覆盖范围内以及/或者Tx UE没有执行网络侧定位的情况下，不执行该发送。
基于对第一信号的接收，Rx UE可以预知在相关联的子帧内会接收到的信息的性质，例如在第一信号指示Tx UE在基站覆盖范围内以及/或者Tx UE执行了网络侧定位的情况下，Rx UE可以预知在相关联的子帧内会接收到Tx UE通过网络侧定位获得的第一定位信息比如Tx UE的绝对位置。这样，Rx UE可以根据在相关联的子帧内会接收到的信息的性质以及/或者自身需求，来确定要采用何种程度的努力来对接收到的数据包进行解码。例如，在Rx UE确定会接收到第一定位信息的情况下，以较高程度的努力来对接收到的数据包进行解码，反之以较低程度的努力来对接收到的数据包进行解码。
可以以显式的方式进行第一信号的通知。例如，通信单元102通过第一信令发送第一信号，第一信令可以为物理层控制信令或高层信令。具体地，第一信令可以为如下之一：侧链路控制指示(Sidelink Control Indicator，SCI)、无线资源控制(Radio Resource Control，RRC)信令、MAC CE。
例如，在Tx UE高速移动的场景下，其基站覆盖状态可能会发生频繁动态变化，即，第一信号的更新较为频繁，因此可以通过SCI来发送第一信号。SCI可以是第一级SCI，也可以是第二级SCI，并且对应于一个新的SCI格式。图3A示出了新的SCI格式的一个示例。其中，该新的SCI格式中的一个比特字段设置为第一信号，用于指示Tx UE的基站覆盖状态以及/或者是否执行了网络侧定位。该比特字段至少包括一个比特。在该比特字段包括一个比特的情况下，例如可以用该比特取值1来表示Tx UE在基站覆盖范围内以及/或者执行了网络侧定位，用该比特取值0来表示Tx UE不在基站覆盖范围内以及/或者没有执行网络侧定位。应该理解，这仅是示例性的，而非限制性的。
类似地，在第一信令为其他信令形式时，第一信号也可以为相应信令中的一个比特字段，并且该比特字段至少包括一个比特，在此不再赘述。
此外，还可以以隐式的方式进行第一信号的通知。例如，第一信号可以为同步信号或信道参考信号，在第一信号符合以下中的一个或多个的情况下，第一信号指示第一通信设备在基站的覆盖范围内以及/或者第一通信设备执行了网络侧定位：第一信号占用特定的时间资源；第一信号占用特定的频率资源；第一信号采用特定的序列。
换言之，可以采用侧链路同步信号块(Sidelink Synchronization Signal Block，S-SSB)或侧链路信道参考信号所占用的时域资源和/或频域资源、或者序列来指示第一通信设备的基站覆盖状态以及/或者是否执行了网络侧定位。例如，可以设置第一资源子集，占用该第一资源子集内的资源的S-SSB或信道参考信号表示第一通信设备在基站覆盖范围内以及/或者执行了网络侧定位，这里的资源可以是时域资源、频域资源和序列中的一种或多种。反之，不占用该第一资源子集内的资源的S-SSB或信道参考信号表示第一通信设备不在基站覆盖范围内以及/或者没有执行网络侧定位。
此外，图2中所示的第一定位信息的发送可以通过物理侧链路共享信道(Physical Sidelink Shared Channel，PSSCH)来进行。例如，当第一信号通过SCI发送时，可以通过与SCI相关联的PSSCH发送第一定位信息。该第一定位信息可以由Rx UE用于进行定位计算，这将在后文中予以具体描述。图3B示出了包括第一定位信息的子帧的一个示例，其中，该子帧包括SCI和与其关联的PSSCH，SCI中包括第一通信设备处于基站覆盖范围内以及/或者第一通信设备执行了网络侧定位的指示，例如SCI中包括上述取值为1的第一信号，关联的PSSCH包括第一定位信息。
另外，通信单元102可以被配置为通过组播或广播发送第一信号和/或第一定位信息，相关的信息流程示意图如图4所示。在图4中，Tx UE通过组播或广播的方式向Rx UE-1至Rx UE-n发送第一信号，并且可选地，在第一信号指示Tx UE在基站覆盖范围内以及/或者执行了网络侧定位的情况下，通过组播或广播的方式向Rx UE-1至Rx UE-n发送第一定位信息。
注意，在下文的描述中，一般以单播为例进行，但是其同样适用于组播或广播的情形。
如前所述，第一定位信息由第二通信设备用于进行定位计算。此外，第一通信设备和第二通信设备之间还可以互相发送定位参考信号，例如以确定相对于彼此的相对位置。
具体地，通信单元102还可以被配置为向第二通信设备发送用于定位测量的第一定位参考信号，其中，第二通信设备基于第一定位参考信号生成第一定位测量结果。通信单元102还被配置为从第二通信设备接收用于定位测量的第二定位参考信号，生成单元101基于第二定位参考信号生成第二定位信息。相关的信息流程例如如图5所示，其中，第一通信设备示出为UE 1，第二通信设备示出为UE 2。
例如，UE 1将接收到第二定位参考信号与发送第一定位参考信号之间的时间差值生成为第二定位信息，UE 2将接收到第一定位参考信号与发送第二定位参考信号之间的时间差值生成为第一定位测量结果。
如图5所示，通信单元102还可以被配置为将第二定位信息发送给第二通信设备。第二通信设备基于第一定位测量结果和第二定位信息进行第一定位计算。例如，在图5的示例中，UE 2在接收到第二定位信息之后，基于第二定位信息ΔT1与第一定位测量结果ΔT2得到信号往返行程时间(Round Trip Time，RTT)RTT＝ΔT1+ΔT2，并基于RTT根据电磁信号传播公式计算得到UE 2与UE 1之间的距离d＝c·RTT/2，其中c为光速3×108m/s。换言之，UE 2通过第一定位计算得到UE 2与UE 1之间的相对位置关系，该相对位置关系后续还可以用于进一步的定位计算，具体示例将在第二实施例中给出。
在另一个示例中，在第一信号指示第一通信设备在基站的覆盖范围内以及/或者第一通信设备执行了网络侧定位的情况下，生成单元101还 被配置为基于网络侧定位获得第一定位信息，基于第一定位信息和第二定位信息确定第二通信设备的位置信息，并且通信单元102将所确定的位置信息发送给第二通信设备。相关的信息流程例如如图6所示，类似地，第一通信设备示出为UE 1，第二通信设备示出为UE 2。
UE 1除了如上生成第二定位信息之外，还基于与基站侧的通信和测量等获得第一定位信息比如UE 1的绝对位置Pos1。应该注意，图6中所示的第一定位信息和第二定位信息的获取并不代表先后顺序，仅是示意性的。UE 1可以基于第二定位信息估计UE 1与UE 2之间的距离d，并基于距离d和Pos1计算得到UE 2的位置信息比如位置范围。或者，UE 1可以从UE 2获取第一定位测量结果，并如上所述基于第二定位信息和第一定位测量结果来计算UE 2与UE 1之间的距离d，进一步基于距离d和Pos1计算得到UE 2的位置范围。
此外，还可以将图5和图6相结合，即，UE 1向UE 2发送第二定位信息和所确定的位置信息两者，这都不是限制性的。
综上所述，根据本实施例的电子设备100通过第一信号来向侧链路通信中的其他通信设备指示本通信设备是否在基站的覆盖范围内以及/或者是否执行了网络侧定位，使得其他通信设备能够基于第一信号进行定位计算，从而提高定位的准确度、效率和灵活性。
<第二实施例>
图7示出了根据本申请的一个实施例的电子设备200的功能模块框图，如图7所示，电子设备200包括：通信单元201，被配置为从第一通信设备接收第一信号，第一信号用于指示第一通信设备是否在基站的覆盖范围内以及/或者第一通信设备是否执行了网络侧定位；以及定位单元202，被配置为使用第一信号进行第二通信设备的定位计算。
其中，通信单元201和定位单元202可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片、处理器。并且，应该理解，图7 中所示的电子设备中的各个功能单元仅是根据其所实现的具体功能而划分的逻辑模块，而不是用于限制具体的实现方式。
电子设备200例如可以设置在第二通信设备侧或可通信地连接到第二通信设备。第一通信设备和第二通信设备例如可以为UE。示例性地，在车辆网(V2X)通信场景下，第一通信设备和第二通信设备可以为V2X中的用户设备，例如可以设置在车辆侧。
这里，还应指出，电子设备200可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备200可以工作为通信设备(比如UE)本身，并且还可以包括诸如存储器、收发器(图中未示出)等外部设备。存储器可以用于存储通信设备实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，其他通信设备、基站等等)间的通信，这里不具体限制收发器的实现形式。
有关第一信号的具体配置和功能在第一实施例中进行了详细描述，相关内容在本实施例中同样适用，因此下文中将适当地省略。
相应地，通信单元201可以通过第一信令接收第一信号，第一信令为物理层控制信令或高层信令，例如如下之一：SCI、RRC信令、MAC CE。第一信号可以为第一信令中的一个比特字段，该比特字段至少包括一个比特。
此外，还可以通过隐式的方式进行第一信号的通知。例如，第一信号可以为同步信号或信道参考信号，定位单元202被配置为在确定第一信号符合以下中的一个或多个的情况下，确定第一通信设备在基站的覆盖范围内以及/或者第一通信设备执行了网络侧定位：第一信号占用特定的时间资源；第一信号占用特定的频率资源；第一信号采用特定的序列。
例如，可以采用侧链路同步信号块S-SSB或侧链路信道参考信号所占用的时域资源和/或频域资源、或者序列来指示第一信号的状态。例如，可以设置第一资源子集，当第二通信设备接收到占用该第一资源子集内的资源的S-SSB或信道参考信号时，确定第一通信设备在基站覆盖范围内以及/或者执行了网络侧定位，这里的资源可以是时域资源、频域资源和序列中的一种或多种。反之，当第二通信设备接收到没有占用该第一资源子集内的资源的S-SSB或信道参考信号时，确定第一通信设备不在 基站覆盖范围内以及/或者没有执行网络侧定位。
通信单元201还被配置为在基于第一信号确定第一通信设备在基站覆盖范围内以及/或者执行了网络侧定位的情况下，在与第一信号相关联的子帧内接收第一通信设备发送的基于网络侧定位而获得的第一定位信息。该第一定位信息例如为第一通信设备的绝对位置，具体地，例如为第一通信设备的经纬度坐标。在另一个示例中，该第一定位信息为第一通信设备的相对位置，具体地，例如为第一通信设备相对于某一参考点的相对位置，如基站的位置可作为参考点。例如，第一定位信息可以由第一通信设备经由PSSCH发送。
如上所述，基于对第一信号的接收，第二通信设备可以预知在相关联的子帧内会接收到的信息的性质，例如在第一信号指示第一通信设备在基站覆盖范围内以及/或者第一通信设备执行了网络侧定位的情况下，第二通信设备可以预知在相关联的子帧内会接收到第一通信设备通过网络侧定位获得的第一定位信息比如第一通信设备的绝对位置。这样，第二通信设备可以根据在相关联的子帧内会接收到的信息的性质，来确定要采用何种程度的努力来对接收到的数据包进行解码。例如，在第二通信设备期望进行精细定位并且通过第一信号确定会接收到第一定位信息的情况下，对相关联的子帧上的PSSCH进行接收和相应的数据解码，反之，如果第二通信设备通过第一信号知悉后续不会收到第一定位信号，则可以放弃对相关联子帧上的PSSCH的接收。
此外，如第一实施例中所述，第一信号和/或第一定位信息可以由第一通信设备通过组播或广播发送。此时，第二通信设备可能为接收到第一信号和/或第一定位信息的通信设备之一。以下的描述虽然以单播为例进行，但是同样适用于组播或广播的情形。
如前所述，第一通信设备和第二通信设备之间可以互相发送定位参考信号，例如以确定相对于彼此的相对位置。相应地，通信单元201被配置为从第一通信设备接收用于定位测量的第一定位参考信号，定位单元202被配置为基于第一定位参考信号生成第一定位测量结果。通信单元201还被配置为向第一通信设备发送用于定位测量的第二定位参考信号，其中，第一通信设备基于第二定位参考信号生成第二定位信息。
在一个示例中，通信单元201被配置为从第一通信设备接收第二定 位信息，定位单元202基于第一定位测量结果和第二定位信息进行第二通信设备的第一定位计算。相关的信息流程例如可参照图5所示。
例如，定位单元202将接收到第一定位参考信号与发送第二定位参考信号之间的时间差值生成为第一定位测量结果。第一通信设备将接收到第二定位参考信号与发送第一定位参考信号之间的时间差值生成为第二定位信息。第一定位计算包括：基于第二定位信息ΔT1与第一定位测量结果ΔT2得到信号往返行程时间RTT＝ΔT1+ΔT2，并基于RTT根据电磁信号传播公式计算得到第一通信设备与第二通信设备之间的距离d＝c·RTT/2，其中c为光速3×108m/s。
在另一个示例中，第一通信设备在基站覆盖范围内以及/或者第一通信设备执行了网络侧定位，基于网络侧定位获得了第一定位信息，并基于第一定位信息和第二定位信息确定第二通信设备的位置信息，通信单元201从第一通信设备接收所确定的第二通信设备的位置信息。相关的信息流程例如可参照图6所示。这里，第一通信设备可以基于第二定位信息确定第一通信设备与第二通信设备之间的距离d，并基于该距离和通过网络侧定位获得的第一通信设备的绝对位置信息Pos1计算得到第二通信设备的位置范围。应该注意，为了提高准确度，通信单元201还可以将第一定位测量结果提供给第一通信设备，以使得第一通信设备如上所述基于第一定位测量结果和第二定位信息来确定距离d。
在通信单元201从第一通信设备接收第二定位信息的情况下，定位单元202还可以进行进一步的定位计算，这将取决于第一通信设备与第二通信设备的基站覆盖状态以及/或者是否执行了网络侧定位。以下将参照图8-图11分别描述第一通信设备和第二通信设备处于不同的基站覆盖状态下时，第二通信设备的定位计算以及相关信息流程的示例。本文中所述的定位计算可以包括下述第一定位计算、第二定位计算、第三定位计算和第四定位计算的部分或全部。
首先描述第一示例：第一通信设备和第二通信设备均在基站覆盖范 围内以及/或者执行了网络侧定位。
其中，定位单元202确定第二通信设备是否在基站的覆盖范围内，在确定第二通信设备在基站的覆盖范围内的情况下，进行网络侧定位以获得第二定位测量结果，并基于第一定位测量结果、第二定位信息和第二定位测量结果进行第二通信设备的第二定位计算。
进一步地，通信单元201还被配置为在基于第一信号确定第一通信设备在基站的覆盖范围内以及/或者第一通信设备执行了网络侧定位的情况下，从第一通信设备接收第一通信设备基于网络侧定位而获得的第一定位信息。
定位单元202基于第一定位信息、第一定位测量结果、第二定位信息和第二定位测量结果进行第二通信设备的第四定位计算。
图8示出了相关的信息流程的示意图，其中，第一通信设备示出为UE 1，第二通信设备示出为UE 2。首先，与前述类似，UE 1和UE 2相互发送定位参考信号，UE 1生成第二定位信息，UE 2生成第一定位测量结果，UE 1将第二定位信息提供给UE 2。UE 2基于第一定位测量结果和第二定位信息执行第一定位计算，例如，得到UE 1和UE 2之间的估计距离d。
另外，UE 1和UE 2分别执行基站覆盖检测，并且判断出UE 1和UE 2分别在gNB 1和gNB 2的基站覆盖范围内。UE1和UE 2分别使用各自的定位管理功能(Location Management Function，LMF)来进行网络侧定位。
在UE 2确定其在基站覆盖范围内时，其使用LMF进行网络侧定位以生成第二定位测量结果比如UE 2的绝对位置信息Pos2。UE 2的定位单元202基于第一定位测量结果、第二定位信息和第二定位测量结果执行第二定位计算，例如，可以基于第一定位测量结果和第二定位信息计算出UE 1与UE 2之间的估计距离d，基于UE2的绝对位置信息Pos2与估计距离d计算得到UE 1的绝对定位范围。
UE 1基于网络侧定位生成第一定位信息比如UE 1的绝对位置信息Pos1，并且生成指示UE 1在基站覆盖范围内以及/或者执行了网络侧定位的第一信号。UE 1将第一信号和第一定位信息发送给UE 2。
UE 2的定位单元202基于第一定位信息、第一定位测量结果、第二定位信息和第二定位测量结果进行第四定位计算，例如，可以基于第一定位测量结果和第二定位信息计算出UE 1与UE 2之间的估计距离d，基于UE 1的绝对位置信息Pos1、UE2的绝对位置信息Pos2与估计距离d来计算UE1与UE2的相对定位。
可以看出，通过第一定位计算、第二定位计算和第四定位计算，UE 2可以获得不同准确度或不同方面的定位信息，提高了定位计算的效率、准确性和灵活性。
定位单元202可以在接收到第一信号之前进行第一定位计算和/或第二定位计算，从而可以及时获得初步的定位信息，进一步提高定位计算的效率。
接着描述第二示例：第一通信设备在基站覆盖范围内以及/或者执行了网络侧定位，第二通信设备不在基站覆盖范围内以及/或者没有执行网络侧定位。
与第一示例中类似地，通信单元201被配置为在基于第一信号确定第一通信设备在基站的覆盖范围内以及/或者第一通信设备执行了网络侧定位的情况下，从第一通信设备接收第一通信设备基于网络侧定位而获得的第一定位信息。
在该示例中，定位单元202基于第一定位信息、第一定位测量结果和第二定位信息进行第二通信设备的第三定位计算。
图9示出了相关的信息流程的示意图，其中，第一通信设备示出为UE 1，第二通信设备示出为UE 2。其中，有关定位参考信号的交互以及第一定位计算的部分与图8中相同，在此不再重复。
UE 1执行基站覆盖检测，并且判断出UE 1在gNB 1的基站覆盖范围内。UE 2执行基站覆盖检测且确定UE 2不在任何基站的覆盖范围内。UE1使用LMF来进行网络侧定位，并生成第一定位信息比如UE 1的绝对位置信息Pos1。此外，UE 1还生成指示UE 1在基站覆盖范围内以及/或者执行了网络侧定位的第一信号。UE 1将第一信号和第一定位信息发送给UE 2。
UE 2的定位单元202基于第一定位信息、第一定位测量结果和第二 定位信息进行第三定位计算，例如，可以基于第一定位测量结果和第二定位信息计算出UE 1与UE 2之间的估计距离d，基于UE 1的绝对位置信息Pos1、估计距离d来计算UE2的位置范围。
同样，从图9可以看出，定位单元202可以在接收到第一信号之前进行第一定位计算，从而可以及时获得初步的定位信息，提高定位计算的效率。
下面描述第三示例：第一通信设备不在基站覆盖范围内以及/或者没有执行网络侧定位，第二通信设备在基站覆盖范围内以及/或者执行了网络侧定位。
在该示例中，定位单元202被配置为在基于第一信号确定第一通信设备不在基站的覆盖范围内以及/或者第一通信设备没有执行网络侧定位的情况下，采用第一定位计算的结果或第二定位计算的结果。
图10示出了相关的信息流程的示意图，其中，第一通信设备示出为UE 1，第二通信设备示出为UE 2。其中，有关定位参考信号的交互以及第一定位计算的部分与图8中相同，在此不再重复。
UE 1执行基站覆盖检测，并且判断出UE 1不在任何基站的覆盖范围内。UE 2执行基站覆盖检测且确定UE 2在gNB 2的覆盖范围内。UE2使用LMF来进行网络侧定位，并生成第二定位测量结果比如UE 2的绝对位置信息Pos2。
UE 2的定位单元202基于第二定位信息、第一定位测量结果和第二定位测量结果进行第二定位计算，例如，可以基于第一定位测量结果和第二定位信息计算出UE 1与UE 2之间的估计距离d，基于UE 2的绝对位置信息Pos2、估计距离d来计算UE 1的绝对定位范围。
此外，UE 1还生成指示UE 1不在基站覆盖范围内以及/或者没有执行网络侧定位的第一信号。UE 1将第一信号发送给UE 2。UE 2在接收到第一信号后获知后续无法获得第一定位信息，从而不再执行其他定位计算。
同样，从图10可以看出，定位单元202可以在接收到第一信号之前进行第一定位计算和第二定位计算，从而可以及时获得初步的定位信息，提高定位计算的效率。
下面描述第四示例：第一通信设备不在基站覆盖范围内以及/或者没有执行网络侧定位，第二通信设备不在基站覆盖范围内以及/或者没有执行网络侧定位。
在该示例中，定位单元202被配置为在基于第一信号确定第一通信设备不在基站的覆盖范围内以及/或者第一通信设备没有执行网络侧定位的情况下，采用第一定位计算的结果。
图11示出了相关的信息流程的示意图，其中，第一通信设备示出为UE 1，第二通信设备示出为UE 2。其中，有关定位参考信号的交互以及第一定位计算的部分与图8中相同，在此不再重复。
UE 1执行基站覆盖检测，并且判断出UE 1不在任何基站的覆盖范围内。UE 2执行基站覆盖检测，并且也判断出UE 2不在任何基站的覆盖范围内。
UE 1生成指示UE 1不在基站覆盖范围内以及/或者没有执行网络侧定位的第一信号。UE 1将第一信号发送给UE 2。UE 2在接收到第一信号后获知后续无法获得第一定位信息，从而不再执行其他定位计算。
同样，从图11可以看出，定位单元202可以在接收到第一信号之前进行第一定位计算，从而可以及时获得初步的定位信息，提高定位计算的效率。
综上所述，根据本实施例的电子设备200通过第一信号来获知侧链路通信中的其他通信设备是否在基站的覆盖范围内以及/或者是否执行了网络侧定位，从而基于第一信号进行定位计算，提高了定位的准确度、效率和灵活性。
作为一种场景的示例，根据本申请的实施例的电子设备100和200可以应用于邻近服务(Proximity Service,ProSe)。第一通信设备和第二通信设备为ProSe中的用户设备。邻近服务例如包括设备间通信(Device to Device,D2D)、车联网(Vehicle to X,V2X，X指车辆、网络基础设施、或者行人等)、机器间网络(Machine to Machine，M2M)、物联网(Internet of Things,IoT)。
以V2X场景为例，第一通信设备和第二通信设备可以为V2X中的 用户设备。其中，判断第一通信设备和第二通信设备是否在基站的覆盖范围内可以包括判断第一通信设备和第二通信设备是否在gNB的覆盖范围内或者是否在作为网络基础设施的路边设备(Roadside Unit,RSU)的覆盖范围内。
应该理解，以上仅是场景的示例，并不是限制性的。本申请的实施例可以应用于任何使用侧链定位的场合。
