具体实施方式
下面结合附图对本公开的具体实施方式进行详细的说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本公开，并不用于限制本公开。
需要说明的是，本公开实施例中的“第一”、“第二”用于区别类似的对象，而不是用于描述特定的顺序或先后次序。本公开实施例中的“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
本公开实施例描述的网络架构以及业务场景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，随着网络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。
目前，在5G定位系统中，5G基站和终端采用的晶振存在频率偏差，因此，终端会默认进行ATA和AFA操作。在5G SL定位系统中，V2X-UE会基于接收到的SSB对接收定时和发送定时进行调整，或者发生覆盖内场景到覆盖外场景的切换时，V2X-UE也会默认进行ATA和/或AFA。
在DL-TDOA、UL-TDOA或Multi-RTT定位方法中，终端的ATA和AFA操作将会影响终端的定位精度。
基于此，本公开实施例提供了一种终端定位方法、终端、基站及LMF。其中，终端定位方法包括：终端按照网络侧设备发送的通知信令进行ATA和/或AFA；其中，通知信令包含指示终端进行ATA和/或AFA的指示信息；终端向LMF发送终端进行ATA和/或AFA的时间信息。通过该方法，LMF可以根据终端相邻两次进行ATA和/或AFA的时间范围内获取的各个定位测量量，确定出终端的位置，进而提高终端定位的精度。
图1为本公开实施例适用的一种终端定位系统的结构示意图。本公开实施例应用于终端定位系统中，该终端定位系统至少包含一个终端101、一个基站102和一个LMF103；其中，基站102可以是为终端101提供服务的服务基站，也可以是与终端101的距离小于距离阈值的相邻基站，距离阈值可以是50米，也可以是100米，本公开对此不做限定。
在一种实施例中，基站102或LMF103可以向终端101发送通知信令，该通知信令中包含指示终端101进行ATA和/或AFA的指示信息；终端101在接收到通知信令后，可以按照通知信令进行ATA和/或AFA操作，并将进行ATA和/或AFA的时间信息发送至LMF103，LMF103可以根据终端101相邻两次进行ATA和/或AFA的时间范围内的各个定位测量量，确定终端的位置。
本公开提供的终端定位方法包括下行定位方法、上行定位方法和直通链路定位方法，下述将分别通过具体的实施例对不同的定位方法进行详细说明。
图2示出了本公开实施例提供的一种下行定位方法的交互流程图，该下行定位方法适用于下行定位或Multi-RTT定位。如图2所示，该方法以网络侧设备和终端a为例进行说明，终端a指代任意一个终端。具体地，该方法包括以下步骤：
步骤S201，终端a向网络侧设备发送终端能力报告。
其中，网络侧设备可以是基站，也可以是LMF，基站可以是为终端a提 供服务的服务基站，也可以是终端a的相邻基站；其中，LMF可以是与终端a或基站连接的LMF。
终端能力报告可以用于表征终端a支持在VAW内进行ATA和/或AFA；或者，终端能力报告也可以用于表征终端a支持按照预定义准则进行所述ATA和/或AFA。
步骤S202，网络侧设备向终端a发送通知信令。
在一种实施例中，当网络侧设备为基站时，通知信令可以为基站发送的RRC信令、MAC CE信令或DCI信令；当网络侧设备为LMF时，通知信令可以为LMF发送的LPP信令。
其中，通知信令中包含指示终端a进行ATA和/或AFA的指示信息；指示信息中可以包括VAW配置参数和优先级类型参数，优先级类型参数用于指示VAW与DL PRS的优先级关系；指示信息中也可以包括预定义准则，该预定义准则用于指示终端a在信号处理时间范围内不进行ATA和/或AFA，在对定位参考信号进行处理之后，进行ATA和/或AFA，其中，信号处理时间范围是指对定位参考信号进行处理的时间范围。
步骤S203，终端a按照网络侧设备发送的通知信令进行ATA和/或AFA。
在一种可选的实施方式中，终端a按照网络侧设备发送的通知信令进行ATA和/或AFA之前，终端a还可以接收LMF发送的DL PRS的资源配置参数，并根据DL PRS的资源配置参数确定出MG或PPW的时间范围。终端a可以在该时间范围内接收基站发送的DL PRS，并对DL PRS进行测量，得到下行定位测量量。
在一种实施例中，假设通知信令中包含指示终端a进行ATA和/或AFA的VAW配置参数和优先级类型参数，终端a在接收到通知信令后，可以将VAW配置参数所指示的VAW所在的时间范围与根据DL PRS的资源配置参数确定的MG或PPW的时间范围进行比对，判断VAW所在的时间范围与MG或PPW的时间范围是否存在重合。
示例性地，在一种实施例中，若VAW所在的时间范围与MG或PPW的 时间范围不重合，如图3所示，L1为VAW所在的时间范围，T1为VAW的开始时刻，T2为VAW的结束时刻，L2为MG或PPW的时间范围，T3为MG或PPW的开始时刻，T4为MG或PPW的结束时刻，终端a可以在VAW所在的时间范围内，即从T1时刻到T2时刻进行ATA和/或AFA；在MG或PPW的时间范围内，即从T3时刻到T4时刻终端a可以对基站发送的DL PRS进行接收，并对DL PRS进行测量，得到下行定位测量量。
在本公开实施例中，下行定位测量量可以包括RSTD、终端收发时间差、下行POA、或下行PDOA。
在另一种实施例中，若VAW所在的时间范围与MG或PPW的时间范围部分重合或完全重合，如图4所示，L3为VAW所在的时间范围，T5为VAW的开始时刻，T6为VAW的结束时刻，L4为MG或PPW的时间范围，T7为MG或PPW的开始时刻，T8为MG或PPW的结束时刻，T5＜T7＜T6＜T8，即VAW所在的时间范围与MG或PPW的时间范围部分重合，终端a可以根据优先级类型参数，确定VAW与DL PRS的优先级关系，并根据VAW与DL PRS的优先级关系，在VAW所在的时间范围内进行ATA和/或AFA。
示例性地，在一种实施例中，若VAW的优先级高于DL PRS的优先级，终端a可以在VAW所在的时间范围内任意选择一个时刻作为第一时刻，并在第一时刻进行ATA和/或AFA，若在第一时刻，终端a接收到基站发送的DL PRS，即终端a进行ATA和/或AFA与对DL PRS进行处理的时刻和/或正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号发生碰撞，则终端a可以将第一时刻接收到的DL PRS进行丢弃，即终端a可以将该DL PRS作为无效信号。若终端a进行ATA和/或AFA与对DL PRS进行处理的时刻和/或OFDM符号没有发生碰撞，则该DL PRS为有效信号，即终端a可以对接收到的DL PRS进行测量，得到下行定位测量量。
在另一种实施例中，若VAW的优先级低于DL PRS的优先级，假设终端a在MG或PPW的时间范围内的第二时刻接收到基站发送的DL PRS，终端a可以对该DL PRS进行测量，得到下行定位测量量，第二时刻为MG或PPW 的时间范围内的任一时刻。终端a可以在VAW所在的时间范围内除第二时刻之外的任一时刻，进行ATA和/或AFA。在本公开实施例中，当一个DL PRS周期内没有可以进行ATA和/或AFA的时刻时，则该周期为无效周期。
在另一种实施例中，假设通知信令中包含指示终端a进行ATA和/或AFA的预定义准则，终端a在接收到通知信令后，可以根据预定义准则，先对接收到的基站发送的DL PRS进行测量，得到下行定位测量量，然后进行ATA和/或AFA；即终端a在对基站发送的DL PRS进行接收并测量的时间范围内不进行ATA和/或AFA。
示例性地，当定位方法为Multi-RTT定位时，在终端a计算终端收发时间差的时间范围，即终端a对DL PRS进行测量，得到下行定位测量量的时间范围内，终端a不能进行ATA和/或AFA，示例性地，如图5所示，终端a计算终端收发时间差的时间范围为[t1-Δt，t2+Δt]，Δt表示余量，t3表示终端a进行ATA和/或AFA的时间范围的开始时刻，t4表示终端a进行ATA和/或AFA的时间范围的结束时刻。
步骤S204，终端a向LMF发送ATA和/或AFA的时间信息。
通过步骤S203，终端a按照通知信令进行ATA和/或AFA后，终端a可以将终端a进行ATA和/或AFA的指示信息和时间信息发送至LMF，其中，指示信息用于指示终端a进行了ATA和/或AFA。
步骤S205，LMF确定终端a的位置。
在一种实施例中，在LMF在对终端a的位置进行确定之前，LMF还可以接收到终端a发送的下行定位测量量，下行定位测量量是终端a在对基站发送的DL PRS进行测量后，发送至LMF的。LMF在终端a相邻两次进行ATA和/或AFA的时间范围内，可能会接收到多个下行定位测量量。
在一种实施例中，在LMF在对终端a的位置进行确定之前，LMF还可以接收到终端a发送的下行定位测量量的质量信息和基站发送的基站位置信息。其中，下行定位测量量的质量信息可以是SNR、SINR或测量误差的方差中的一种或多种。
通过上述方式，LMF可以接收到终端a每次进行ATA和/或AFA之后，发送的进行ATA和/或AFA的时间信息，进而确定终端a相邻两次进行ATA和/或AFA的时间。LMF可以根据在终端a相邻两次进行ATA和/或AFA的时间范围内，接收到的终端a发送的下行定位测量量、下行定位测量量的质量信息和终端a关联的各个基站的位置信息，确定出终端a的位置。
具体地，在一种实施例中，LMF可以根据接收到的下行定位测量量和下行定位测量量的质量信息，采用公式1和公式2确定tk时刻对应的加权处理后的下行定位测量量。其中，tk时刻可以是终端a相邻两次进行ATA和/或AFA的时间范围内的任一时刻。
x(k)＝f(xm(k),xm(k-1),xm(k-2),…xm(k-M))  (公式1)
f(n)＝a0fm(n)+a1fm(n-1)+a2fm(n-2)+…+aM-1fm(n-M+1)  
(公式2)
其中，x(k)表示在tk时刻加权处理后的下行定位测量量，例如：RSTD和终端收发时间差；xm(i)表示在时刻ti上报的、未经过加权处理的下行定位测量量，i的取值可以为k，k-1，……，k-M；f(n)为加权函数，取决于加权算法；M表示终端相邻两次进行ATA和/或AFA的时间范围内上报的下行定位测量量的个数；{a0,a1,…,aM-1}为加权器参数，且
加权参数可以根据不同的加权器算法和/或定位测量量的质量信息进行确定。例如，当加权器算法为平均值加权算法时，加权参数可以为a0＝a1＝…＝aM-1＝1/M；或者加权参数可以为a0＝1，a1＝…＝aM-1＝0；或者加权参数可以为aM-1＝1，a0＝…＝aM-2＝0；或者加权参数可以为an＝1，a0＝…＝aM-1＝0，其中，an对应的下行定位测量量的测量质量最高。
确定在终端a相邻两次进行ATA和/或AFA的时间范围内的各个时刻对应的加权处理后的下行定位测量量之后，LMF可以各个时刻对应的加权处理后的下行定位测量量和各个基站的位置信息，确定出终端a的位置。
图6示出了本公开实施例提供的一种上行定位方法的交互流程图，该上 行定位方法适用于上行定位或Multi-RTT定位；如图6所示，该方法以网络侧设备和终端a为例进行说明，终端a指代任意一个终端。具体地，该方法包括以下步骤：
步骤S601，终端a向网络侧设备发送终端能力报告。
步骤S602，网络侧设备向终端a发送通知信令。
步骤S603，终端a按照网络侧设备发送的通知信令进行ATA和/或AFA。
在一种可选的实施方式中，终端a按照网络侧设备发送的通知信令进行ATA和/或AFA之前，终端a还可以接收到基站发送的UL SRS-Pos的资源配置参数，并根据UL SRS-Pos的资源配置参数确定出终端a向基站发送UL SRS-Pos的时间范围。
在一种实施例中，假设通知信令中包含指示终端a进行ATA和/或AFA的VAW配置参数和优先级类型参数，终端a在接收到通知信令后，可以将VAW配置参数所指示的VAW所在的时间范围与根据UL SRS-Pos的资源配置参数确定出终端a向基站发送UL SRS-Pos的时间范围进行比对，判断VAW所在的时间范围与终端a向基站发送UL SRS-Pos的时间范围是否存在重合。
在一种实施例中，若VAW所在的时间范围与终端a向基站发送UL SRS-Pos的时间范围不重合，如图7所示，时隙#1(slot#1)为VAW所在的时间范围，时隙#2(slot#2)为终端a向基站发送UL SRS-Pos的时间范围；终端a可以在VAW所在的时间范围内，即slot#1内进行ATA和/或AFA；在终端a向基站发送UL SRS-Pos的时间范围内，即slot#2内向基站发送UL SRS-Pos。
在另一种实施例中，若VAW所在的时间范围与终端a向基站发送UL SRS-Pos的时间范围部分重合或完全重合，则终端a可以根据优先级类型参数，确定VAW与UL SRS-Pos的优先级关系，并根据VAW与UL SRS-Pos的优先级关系，在VAW所在的时间范围内进行ATA和/或AFA。
示例性地，在一种实施例中，若VAW的优先级高于UL SRS-Pos的优先级，终端a可以在VAW所在的时间范围内任意选择一个时刻作为第一时刻， 并在第一时刻进行ATA和/或AFA，若在第一时刻，终端a需要向基站发送UL SRS-Pos，即终端a进行ATA和/或AFA与对UL SRS-Pos进行处理的时刻和/或正交频分复用OFDM符号发生碰撞，则终端a将该UL SRS-Pos作为无效信号，即不向基站发送UL SRS-Pos，若终端a进行ATA和/或AFA与对UL SRS-Pos进行处理的时刻和/或正交频分复用OFDM符号没有发生碰撞，则该UL SRS-Pos为有效信号，终端a可以向基站发送UL SRS-Pos。
在另一种实施例中，若VAW的优先级低于UL SRS-Pos的优先级，假设终端a在终端a向基站发送UL SRS-Pos的时间范围内的第二时刻向基站发送UL SRS-Pos，第二时刻为终端a向基站发送UL SRS-Pos的时间范围内的任一时刻。终端a可以在VAW所在的时间范围内除第二时刻之外的任一时刻，进行ATA和/或AFA。在本公开实施例中，当一个UL SRS-Pos周期内没有可以进行ATA和/或AFA的时刻时，则该周期为无效周期。
在另一种实施例中，假设通知信令中包含指示终端a进行ATA和/或AFA的预定义准则，终端a在接收到通知信令后，可以根据预定义准则，先向基站发送UL SRS-Pos，然后进行ATA和/或AFA；即终端a在向基站发送UL SRS-Pos的时刻不进行ATA和/或AFA。
步骤S604，基站对UL SRS-Pos进行测量，得到上行定位测量量。
通过步骤S603，基站在接收到终端a发送的UL SRS-Pos后，可以对UL SRS-Pos进行测量，得到上行定位测量量。上行定位测量量可以包括RTOA，基站收发时间差、上行POA、或上行PDOA。
步骤S605，基站向LMF发送上行定位测量量。
步骤S606，终端a向LMF发送ATA和/或AFA的时间信息。
通过步骤S603，终端a按照通知信令进行ATA和/或AFA后，终端a可以将终端a进行ATA和/或AFA的指示信息时间信息发送至LMF。
步骤S607，LMF确定终端a的位置。
在一种实施例中，在LMF在对终端a的位置进行确定之前，LMF还可以接收到基站发送的基站位置信息。
通过上述方式，LMF可以接收到终端a每次进行ATA和/或AFA之后，发送的进行ATA和/或AFA的时间信息，进而确定终端a相邻两次进行ATA和/或AFA的时间。LMF可以根据在终端a相邻两次进行ATA和/或AFA的时间范围内，接收到的基站发送的上行定位测量量和终端a关联的各个基站的位置信息，确定出终端a的位置。
示例性地，LMF可以根据公式1和公式2确定出终端a的位置，具体实施方式与上述下行定位方法的步骤相似，此处不再赘述。
图8示出了本公开实施例提供的一种直通链路定位方法的交互流程图，该方法以网络侧设备和接收终端a为例进行说明，接收终端a指代任意一个接收终端。如图8所示，该方法包括以下步骤：
步骤S801，接收终端a向网络侧设备发送终端能力报告。
步骤S802，网络侧设备向接收终端a发送通知信令。
步骤S803，接收终端a按照网络侧设备发送的通知信令进行ATA和/或AFA。
在一种可选的实施方式中，接收终端a按照网络侧设备发送的通知信令进行ATA和/或AFA之前，接收终端a还可以接收到LMF发送的SL PRS的资源配置参数，并根据SL PRS的资源配置参数确定出MG或PPW的时间范围。接收终端a可以在该时间范围内接收发送终端b发送的SL PRS，并对SL PRS进行测量，得到直通链路定位测量量。
在一种实施例中，假设通知信令中包含指示接收终端a进行ATA和/或AFA的VAW配置参数和优先级类型参数，接收终端a在接收到通知信令后，可以将VAW配置参数所指示的VAW所在的时间范围与根据SL PRS的资源配置参数确定的MG或PPW的时间范围进行比对，判断VAW所在的时间范围与MG或PPW的时间范围是否存在重合。
在一种实施例中，若VAW所在的时间范围与MG或PPW的时间范围不重合，接收终端a可以在VAW所在的时间范围内，进行ATA和/或AFA；在MG或PPW的时间范围内，对发送终端b发送的SL PRS进行接收，并对SL  PRS进行测量，测到直通链路定位测量量。
在本公开实施例中，直通链路定位测量量可以包括TDOA、接收终端的终端收发时间差、SL POA、或SL PDOA。
在另一种实施例中，若VAW所在的时间范围与MG或PPW的时间范围部分重合或完全重合，则接收终端a可以根据优先级类型参数，确定VAW与DL PRS的优先级关系，并根据VAW与SL PRS的优先级关系，在VAW所在的时间范围内进行ATA和/或AFA。
示例性地，在一种实施例中，若VAW的优先级高于SL PRS的优先级，接收终端a可以在VAW所在的时间范围内任意选择一个时刻作为第一时刻，并在第一时刻进行ATA和/或AFA，若在第一时刻，接收终端a接收到发送终端b发送的DL PRS，即接收终端a进行ATA和/或AFA与对SL PRS进行处理的时刻和/或正交频分复用OFDM符号发生碰撞，则接收终端a可以将第一时刻对应的SL PRS进行丢弃，即接收终端a可以将该SL PRS作为无效信号。若接收终端a进行ATA和/或AFA与对SL PRS进行处理的时刻和/或正交频分复用OFDM符号没有发生碰撞，则该SL PRS为有效信号，即接收终端a可以对接收到的发送终端b发送的SL PRS进行测量，得到直通链路定位测量量。
在另一种实施例中，若VAW的优先级低于SL PRS的优先级，假设接收终端a在MG或PPW的时间范围内的第二时刻接收到发送终端b发送的SL PRS，接收终端a可以对该SL PRS进行测量，得到直通链路定位测量量，第二时刻为MG或PPW的时间范围内的任一时刻。接收终端a可以在VAW所在的时间范围内除第二时刻之外的任一时刻，进行ATA和/或AFA。在本公开实施例中，当一个SL PRS周期内没有可以进行ATA和/或AFA的时刻时，则该周期为无效周期。
在另一种实施例中，假设通知信令中包含指示接收终端a进行ATA和/或AFA的预定义准则，接收终端a在接收到通知信令后，可以根据预定义准则，先对接收的SL PRS进行测量，得到直通链路定位测量量，然后进行ATA 和/或AFA；即接收终端a在对发送终端b发送的SL PRS进行接收并测量的时间范围内不进行ATA和/或AFA。
步骤S804，接收终端a向LMF发送ATA和/或AFA的时间信息。
通过步骤S803，接收终端a按照通知信令进行ATA和/或AFA后，接收终端a可以将接收终端a进行ATA和/或AFA的指示信息和时间信息发送至LMF，其中，指示信息用于指示接收终端a进行了ATA和/或AFA。
步骤S805，LMF确定接收终端a的位置。
在一种实施例中，在LMF在对接收终端a的位置进行确定之前，LMF还可以接收到接收终端a发送的直通链路定位测量量，直通链路定位测量量是接收终端a在对发送终端b发送的SL PRS进行测量后，发送至LMF的。LMF在接收终端a相邻两次进行ATA和/或AFA的时间范围内，可能会接收到多个直通链路定位测量量。
在一种实施例中，在LMF在对接收终端a的位置进行确定之前，LMF还可以接收到接收终端a发送的直通链路定位测量量的质量信息和基站发送的基站位置信息。其中，直通链路定位测量量的质量信息可以是SNR、SINR或测量误差的方差中的一种或多种。
通过上述方式，LMF可以接收到接收终端a每次进行ATA和/或AFA之后，发送的进行ATA和/或AFA的时间信息，进而确定接收终端a相邻两次进行ATA和/或AFA的时间。LMF可以根据在接收终端a相邻两次进行ATA和/或AFA的时间范围内，接收到的接收终端a发送的下行定位测量量、下行定位测量量的质量信息和接收终端a关联的各个基站的位置信息，确定出接收终端a的位置。
示例性地，LMF可以根据公式1和公式2确定出终端a的位置，具体实施方式与上述下行定位方法的步骤相似，此处不再赘述。
图9示出了本公开实施例提供的另一种直通链路定位方法的交互流程图，该方法以网络侧设备和发送终端b为例进行说明，发送终端b指代任意一个发送终端。如图9所示，该方法包括以下步骤：
步骤S901，发送终端b向网络侧设备发送终端能力报告。
步骤S902，网络侧设备向发送终端b发送通知信令。
步骤S903，发送终端b按照网络侧设备发送的通知信令进行ATA和/或AFA。
在一种可选的实施方式中，发送终端b按照网络侧设备发送的通知信令进行ATA和/或AFA之前，发送终端b还可以接收到基站发送的SL PRS的资源配置参数，并根据SL PRS的资源配置参数确定出发送终端b向接收终端a发送SL PRS的时间范围。
在一种实施例中，假设通知信令中包含指示发送终端b进行ATA和/或AFA的VAW配置参数和优先级类型参数，发送终端b在接收到通知信令后，可以将VAW配置参数所指示的VAW所在的时间范围与根据SL PRS的资源配置参数确定出发送终端b向接收终端a发送SL PRS的时间范围进行比对，判断VAW所在的时间范围与发送终端b向接收终端a发送SL PRS的时间范围是否存在重合。
在一种实施例中，若VAW所在的时间范围与发送终端b向接收终端a发送SL PRS的时间范围不重合，发送终端b可以在VAW所在的时间范围内进行ATA和/或AFA；在发送终端b向接收终端a发送SL PRS的时间范围内，向接收终端a发送SL PRS。
在另一种实施例中，若VAW所在的时间范围与发送终端b向接收终端a发送SL PRS的时间范围部分重合或完全重合，则发送终端b可以根据优先级类型参数，确定VAW与SL PRS的优先级关系，并根据VAW与SL PRS的优先级关系，在VAW所在的时间范围内进行ATA和/或AFA。
示例性地，在一种实施例中，若VAW的优先级高于SL PRS的优先级，发送终端b可以在VAW所在的时间范围内任意选择一个时刻作为第一时刻，并在第一时刻进行ATA和/或AFA，若在第一时刻，发送终端b需要向接收终端a发送SL PRS，即发送终端b进行ATA和/或AFA与对SL PRS进行处理的时刻和/或正交频分复用OFDM符号发生碰撞，则发送终端b可以将该SL  PRS作为无效信号，即不向接收终端a发送SL PRS，若发送终端b进行ATA和/或AFA与对UL SRS-Pos进行处理的时刻和/或正交频分复用OFDM符号没有发生碰撞，则该SL PRS为有效信号，即发送终端b可以向接收终端a发送SL PRS。
在另一种实施例中，若VAW的优先级低于SL PRS的优先级，假设发送终端b在发送终端b向接收终端a发送SL PRS的时间范围内的第二时刻向接收终端a发送SL PRS，第二时刻为发送终端b向接收终端a发送SL PRS的时间范围内的任一时刻。发送终端b可以在VAW所在的时间范围内除第二时刻之外的任一时刻，进行ATA和/或AFA。在本公开实施例中，当一个SL PRS周期内没有可以进行ATA和/或AFA的时刻时，则该周期为无效周期。
在另一种实施例中，假设通知信令中包含指示发送终端b进行ATA和/或AFA的预定义准则，发送终端b在接收到通知信令后，可以按照预定义准则，先向接收终端a发送SL PRS，然后进行ATA和/或AFA；即发送终端b在向接收终端a发送SL PRS的时刻不进行ATA和/或AFA。
步骤S904，接收终端a对SL PRS进行测量，得到直通链路定位测量量。
通过步骤S903，接收终端a在接收到发送终端b发送的SL PRS后，可以对SL PRS进行测量，得到直通链路定位测量量。
步骤S905，接收终端a向LMF发送直通链路定位测量量。
步骤S906，发送终端b向LMF发送ATA和/或AFA的时间信息。
通过步骤S903，发送终端b按照通知信令进行ATA和/或AFA后，发送终端b可以将发送终端b进行ATA和/或AFA的指示信息时间信息发送至LMF。
步骤S907，LMF确定发送终端b的位置。
在一种实施例中，在LMF在对发送终端b的位置进行确定之前，LMF还可以接收到基站发送的基站位置信息。
通过上述方式，LMF可以接收到发送终端b每次进行ATA和/或AFA之后，发送的进行ATA和/或AFA的时间信息，进而确定发送终端b相邻两次进行ATA和/或AFA的时间。LMF可以根据在发送终端b相邻两次进行ATA 和/或AFA的时间范围内，接收到的接收终端a发送的上行定位测量量和发送终端b关联的各个基站的位置信息，确定出发送终端b的位置。
示例性地，LMF可以根据公式1和公式2确定出终端a的位置，具体实施方式与上述下行定位方法的步骤相似，此处不再赘述。
在本公开实施例中，图8和图9所示的直通链路定位方法，也适用于Multi-RTT定位。当定位方法为Multi-RTT定位时，在接收终端a和发送终端b计算终端收发时间差的时间范围，即接收终端a对SL PRS进行测量，得到直通链路定位测量量的时间范围内，接收终端a和发送终端b均不能进行ATA和/或AFA。示例性地，如图10所示，[t5-Δt1，t6+Δt1]为接收终端a计算终端收发时间差的时间范围，t9表示接收终端a进行ATA和/或AFA的时间范围的开始时刻，t10表示接收终端a进行ATA和/或AFA的时间范围的结束时刻，Δt1表示余量，且Δt1≥0；[t7-Δt2，t8+Δt2]为发送终端b计算终端收发时间差的时间范围，t11表示发送终端b进行ATA和/或AFA的时间范围的开始时刻，t12表示发送终端b进行ATA和/或AFA的时间范围的结束时刻，Δt2表示余量，且Δt2≥0，接收终端a和发送终端b之间SL PRS的RTT可以用公式3表示。
RTT＝T1+T2＝(t5-t7)+(t8-t6)＝(t5-t6)+(t8-t7)  (公式3)
在一种实施例中，在图8和图9所示的直通链路定位方法中，发送终端b和接收终端a是相对而言的，示例性地，UE1可以向UE2发送SL PRS，也可以接受UE2发送的SL PRS，因此，对于UE2而言，UE1既可以是发送终端，也可以是接收终端。
在该实施例中，可以将发送终端b看作接收终端a的基站。示例性地，如图11所示，当UE2为发送终端，UE1为接收终端时，假设5ms的SL PRS周期内包含4个连续的SL slot，UE2可以指示UE1在第一个SL slot，即slot#3(时隙#3)进行ATA和/或AFA操作，UE2可以在第二个SL slot，即slot#4(时隙#4)进行ATA和/或AFA操作；UE1可以在第三个SL slot，即slot#5(时隙#5)内向UE2发送SRS-Pos1；UE2可以在第四个SL slot，即slot#6(时 隙#6)内向UE1发送SRS-Pos2。从而可以实现在终端对SL PRS进行处理的时间范围内，不进行ATA和/或AFA操作。
