Description

定位方法与通信装置
本申请要求于2022年11月21日提交中国国家知识产权局、申请号为202211457230.1、申请名称为“定位方法与通信装置”的中国专利申请的优先权以及于2022年10月9日提交中国国家知识产权局、申请号为202211231689.X、申请名称为“一种测量报告的传输方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，更具体地，涉及一种定位方法与通信装置。
背景技术
第五代移动通信技术正在进行侧行链路(sidelink，SL)定位的标准化工作。其中，传统的定位方案，例如，到达时间差(time difference of arrival，TDOA)、往返时间(round-trip time，RTT)等，都需要重新评估其在SL场景下的性能。
以RTT方案为例，RTT方案虽然不要求设备间的严格同步，但由于时钟漂移现象，定位参考信号(positioning reference signal，PRS)的发送设备会对PRS的发送时间的记录产生时间偏差，PRS的测量设备会对PRS的接收时间的记录产生时间偏差，这两个时间偏差会影响RTT方案的定位精度。
发明内容
本申请提供一种定位方法与通信装置，能够提升定位的定位精度。
第一方面，提供了一种定位方法，包括：向第一通信装置发送第一信号，其用于第一通信装置与第二通信装置之间的定位；接收来自于第一通信装置的第一信号的第一测量报告，第一测量报告包括第一测量值与第一符号索引，第一符号索引用于指示第一通信装置获取第一测量值的符号；接收来自于第一通信装置的第二信号，其用于第一通信装置与第二通信装置之间的定位；对第二信号进行测量，得到第二信号的第二测量报告，第二测量报告包括第三测量值；根据第一关系、第一测量值、第三测量值以及第一符号索引，确定第一通信装置与第二通信装置之间的飞行时间；第一关系用于指示第一通信装置的时钟晶振误差与第二通信装置的时钟晶振误差之间的关系。
具体而言，第一符号索引用于指示第一通信装置获取第一测量值的符号，可以为：第一通信装置在第一符号索引所指示的符号对第一信号进行测量，并得到第一测量值。
应理解，第一关系可以是第二通信装置基于与第一通信装置此前的多次定位测量确定的，也可以是基于其他方式进行确定的，在此不做过多描述。因此，在上述技术方案中，第二通信装置在已知第一关系的前提下能够根据第一测量值、第一符号索引以及第三测量值确定第一通信装置与第二通信装置之间的飞行时间。
通过在测量报告中增加符号索引，第二通信装置(为上述技术方案的执行主体)能够获取第一通信装置获取第一测量值的符号位置的信息，便于在确定第一通信装置与第二通信装置之间的飞行时间时，根据第一通信装置的时钟晶振误差与第二通信装置的时钟晶振误差的关系，将第一测量值转换为第二通信装置对应的测量结果，从而降低时钟漂移误差对定位测量结果的影响，能够提升定位的定位精度。
一个可能的实现方式中，该方法还包括：向第一通信装置发送指示信息，其用于指示第一通信装置在第一符号索引指示的符号获取第一测量值，以及，在第二符号索引指示的符号获取第二测量值，第二符号索引用于指示第一通信装置获取第二测量值的符号。
如此，第一通信装置根据第二通信装置的指示信息向第二通信装置上报第一测量值、第一符号索引、第二测量值以及第二符号索引。如此，便于第二通信装置根据第一通信装置上报的多个测量值与多个符号索引确定第一通信装置的时钟晶振误差与第二通信装置的时钟晶振误差之间的关系。
一个可能的实现方式中，该指示信息还包括第一符号索引与第二符号索引。
如此，第一通信装置在第二通信装置指示的两个符号分别对第一信号进行测量，并得到两个测量值。
一个可能的实现方式中，第一测量报告还包括第二测量值与第二符号索引；第一测量值、第一符号索引、第二测量值以及第二符号索引用于第一关系的确定。
如前文所述，第一关系可以是第二通信装置通过其他方式确定的，其他方式可以包括：第一测量报告携带多个测量值与多个符号索引。相应地，第二通信装置根据第一测量报告中携带的多个测量值与多个符号索引计算得到第一通信装置与第二通信装置之间的时钟晶振误差的关系，即第一关系。进而，第二通信装置根据基于多个测量值与多个符号索引计算得到的第一关系、第一测量值、第一符号索引以及第三测量值确定第一通信装置与第二通信装置之间的飞行时间。
综上所言，通过上报多个测量值与多个符号索引，且每个测量值对应一个符号索引，第二通信装置根据第一通信装置上报的多个测量值与多个符号索引确定第一通信装置的时钟晶振误差与第二通信装置的时钟晶振误差之间的关系，进而能够确定第一通信装置与第二通信装置之间的飞行时间。

下文将对与本申请揭示的技术方案有关的技术作简短的描述。
图2是一种定位方法200的示意图。如图2所示，终端设备A在时间T1发送PRS1，终端设备B在时间T2接收到PRS1；终端设备B在时间T3发送PRS2，终端设备A在时间T4接收到PRS2。其中，上述的四个时间之间满足如下关系：T4晚于T3，T3晚于T2，T2晚于T1。
其中，终端设备A与终端设备B之间的距离D为：
D＝TOF*c   (1)
公式(1)中，c用于指示无线信号的飞行速度(一般为光速)，TOF用于指示终端设备A与终端设备B之间的飞行时间(time of flight，TOF)。其中，TOF为：
TOF＝0.5*(Tround-Treply),Tround＝(T4-T1),Treply＝(T3-T2)   (2)
由于时钟漂移现象(设备的时钟晶振有误差e1，如果实际经过时间t，设备记录的时间则为t(1+e1))的存在，终端设备A与终端设备B均会对PRS的发送与接收的记录时间产生偏差。因此，TOF应表示为：
TOF＝0.5*|Tround,1*(1+eA)-Treply,1*((1+eB)|
＝TOF1+0.5*(Tround,1*eA-Treply,1*eB)
＝TOF1+0.5*Treply,1*(eA-eB)+TOF1*eA，   (3)
其中，TOF1用于指示真实的TOF，Tround,1用于指示真实的往返时间，Treply,1用于指示真实的响应时间，eA为终端设备A的时钟晶振误差，eB为终端设备B的时钟晶振误差。
一般而言，eA为10-6量级，TOF1为纳秒级，TOF1*eA可以忽略不计。由于Treply,1为毫秒级，0.5*Treply,1*(eA-eB)会引入纳秒级别的误差(无线信号在1纳秒的时长内可以传输30厘米)。因此，基于公式(3)得到的终端设备A与终端设备B之间的距离D与终端设备A与终端设备B之间的实际距离会存在偏差。
目前，3GPP协议为RTT方案定义了测量量(UE Rx-Tx Time difference)的概念，该测量量通过间接指示收发时间的间隔来计算TOF。具体来说，终端设备B在接收到PRS1后测定PRS1的首径到达时间，并基于该首径到达时间确定PRS1的接收子帧的起始时间(TUE-RX)。然后，终端设备B找到与PRS1的接收子帧最近的一个发送子帧，并得到该发送子帧的起始时间(TUE-TX)。于是，终端设备B确定UE Rx-Tx Time difference(记为ΔtB)等于TUE-RX-TUE-TX。类似地，终端设备B向终端设备A发送PRS2，终端设备A基于PRS2确定一个新的UE Rx-Tx Time difference，记为Δt_A。此时，TOF＝0.5*|ΔtA-ΔtB|。
由于时钟漂移现象，终端设备B在一个时隙内的不同符号测得的首径到达时间会有偏差。示例性 地，终端设备B在时隙#1的第二个符号测得首径到达时间#1，在第六个符号测得首径到达时间#2。虽然第六个符号与第二个符号之间仅间隔4个符号，但是由于时钟漂移现象，第六个符号与第二个符号之间实际间隔的时间并不等于4个符号的长度。终端设备B基于时隙#1的第二个符号推导得到的PRS1的接收子帧的起始时间与基于时隙#1的第六个符号推导得到的PRS1的接收子帧的起始时间会存在偏差。但是该偏差不会体现在终端设备B向终端设备A上报的测量报告(measurement report，MR)之中。因此，上述的时钟漂移现象会影响终端设备A与终端设备B之间的定位测量结果的准确性，从而会影响到终端设备A与终端设备B之间的定位精度。
鉴于上述技术问题，本申请提供一种定位方法与通信装置，能够提高定位的定位精度。
下文将结合附图对本申请实施例揭示的定位方法进行描述。
图3是本申请实施例的定位方法300的交互流程示意图。图3中的方法流程示例性地可以由第一通信装置与第二通信装置执行，或者由安装于第一通信装置与第二通信装置中的具有相应功能的模块和/或器件(例如，芯片或集成电路等)执行，本申请对此不限定。另外，图3中的方法流程也可以为第一通信装置、第二通信装置以及第三通信装置执行，或者由安装于第一通信装置、第二通信装置以及第三通信装置中的具有相应功能的模块和/或器件(例如，芯片或集成电路等)执行。为便于描述，本申请实施例以图3中的方法流程由第一通信装置与第二通信装置执行，但不限定由多个通信装置共同执行图3所示的方法的场景。其中，第一通信装置可以为终端设备或者网络设备，第二通信装置也可以为终端设备或者网络设备，本申请不限定。另外，本申请不仅适用于网络设备与终端设备之间的通信，也适用于终端设备之间的通信，还可以适用于网络设备之间的通信，或者，其他设备之间的通信等，本申请对此也不限定。如图3所示，方法300包括：
S310、第二通信装置向第一通信装置发送第一信号。
相应地，第一通信装置接收来自于第二通信装置的第一信号，其用于第一通信装置与第二通信装置之间的定位。
具体来说，第二通信装置向第一通信装置发送的第一信号是用于实现第一通信装置与第二通信装置之间的定位，本申请对第一信号的类型不做限定。
一个可能的实现方式，第一信号的类型包括PRS，或者，侧行链路定位信号(sidelink positioning reference signal，SL-PRS)等。另外，第一信号的类型还可以包括未来3GPP标准或者技术中用于实现定位的信号类型，本申请对此不做限定。
S320、第一通信装置对第一信号进行测量，得到测量报告1，其包括测量值A(譬如，第一测量值)与符号索引A(譬如，第一符号索引)。
第一通信装置可以按照现行的对第一信号进行测量的方式进行测量，也可以按照其他的方式对第一信号进行测量，本申请对此不做限定。
第一通信装置完成对第一信号的测量后，得到第一信号的测量报告1。其中，测量报告1包括测量值A与符号索引A。其中，测量值A指示第一通信装置对第一信号进行测量得到的第一测量结果。符号索引A用于指示测量值A的获取符号，换言之，符号索引A用于指示时隙A内的符号S，第一通信装置在符号S对第一信号进行测量，并得到测量值A。可选地，符号索引A用于指示第一通信装置获取测量值A的符号。
应理解，符号索引A用于指示测量值A的获取符号，可以为：第一通信装置在符号索引A所指示的符号对第一信号进行测量，得到测量值A。
一个可能的实现方式，测量报告1还可以包括时隙标识A，其用于指示第一通信装置在具体的某个时隙接收到第一信号，即：时隙标识A用于指示第一信号的接收时隙(下文用时隙A指示)。
正如前文所述，第一通信装置在时隙A内的不同符号进行测量，可以得到多个不同的首径到达时间，相应地，第一通信装置也会得到多个不同的测量值。其中，时隙A内的不同符号与不同的测量值之间的关系可以见表1。
表1

如表1所示，不同的符号索引指示不同的符号。示例性地，符号索引0指示时隙A中的第一个符号，符号索引1指示时隙A中的第二个符号，…，符号索引N指示时隙A中的第N+1个符号。其中，符号索引之间的差值可以指示各自对应的符号之间的间隔符号的数量。譬如，符号索引5与符号索引1之间的差值为4，则可以指示符号索引5指示的第六个符号与符号索引1指示的第二个符号之间的间隔符号的数量为4。另外，不同的符号索引对应不同的测量值。示例性地，符号索引0对应测量值1，符号索引1对应测量值2，…，符号索引N对应测量值n。综上，符号索引与测量值之间存在对应关系(可以见表1)。
S330、第一通信装置向第二通信装置发送测量报告1。
相应地，第二通信装置接收来自于第一通信装置发送的测量报告1。
S340、第一通信装置向第二通信装置发送第二信号，其用于第二通信装置与第一通信装置之间的定位。
相应地，第二通信装置接收来自于第一通信装置的第二信号，并对第二信号进行测量得到第二信号的测量报告2。其中，测量报告2包括测量值C(譬如，第三测量值)。
应理解，第二通信装置对第二信号进行测量的相关描述可以参见前述的第一通信装置对第一信号进行测量的描述，在此不再赘述。
可以理解的是，第二通信装置对第二信号进行测量，得到测量报告2。举例来说，测量报告2可以不包括符号索引以及时隙标识等，其可以仅包括测量值C，本申请对此不做限定。
S350、第二通信装置根据第一关系、测量值A、测量值C以及符号索引A确定第一通信装置与第二通信装置之间的飞行时间。
应理解，第一关系用于指示第一通信装置的时钟晶振误差与第二通信装置的时钟晶振误差之间的关系。其中，第一关系的表达形式可以为：[(1+eA)/(1+eB)]或者[Ta/Tb]等，本申请对此不做限定。
一个示例中，第一关系是由第二通信装置基于与第一通信装置此前的多次定位测量确定的。另一个示例中，第一关系是由第二通信装置根据第一通信装置上报的多个测量值与多个符号索引计算确定的。其中，关于后一个示例将在后文做进一步的描述。
在完成对第二信号的测量后，第二通信装置得到第二信号的测量报告2，并结合第一通信装置上报的第一信号的测量报告1，基于如下公式(4)确定第一通信装置与第二通信装置之间的距离D。
其中，Treply是第二通信装置根据测量报告1得到的，Tround是第二通信装置根据测量报告2得到的。由公式(4)可知，经由公式(4)得到的TOF只引入了eA*TOF1的误差。由于eA为10-6量级，TOF1为纳秒级，TOF1·eA可以忽略不计。因此，相比于公式(3)，公式(4)得到的TOF的误差更小，所以能够提高定位的定位精度。
一种可能的实现方式，第二通信装置已经获取第一通信装置的时钟晶振误差与第一通信装置的时钟晶振误差之间的关系那么就可以利用将公式(4)中的Treply转换为第二通信装置的时钟晶振下对应的时间，从而得到定位误差更小的定位结果。
另一种可能的实现方式，第二通信装置利用前述的测量报告1中携带多个测量值的方式推算
又一个可能的实现方式，本申请也支持通过多个测量报告1(每个测量报告1中只有一个测量值)获取其中，可以指代前述的第一关系。
一个可能的实现方式中，S350中的TOF可以满足：
在公式(5)中，|ΔtA|指示测量值C，|ΔtB|指示测量值A。其中，Δt为符号索引A与测量值C所对应的符号索引分别确定的符号之间的时间间隔。其中，第二通信装置能够确定测量值C所对应的符 号，因此，第二通信装置可以根据测量值A、测量值C、符号索引A以及测量值C所对应的符号索引确定第一通信装置与第二通信装置之间的飞行时间。
具体来说，第二通信装置获取测量值A的测量符号信息后，其根据第一关系降低由第一通信装置的时钟漂移现象对定位测量结果的影响，可以确定第一通信装置的误差较小的Treply，最终确定第一通信装置与第二通信装置之间的误差较小的飞行时间。
通过在测量报告中增加符号索引，第二通信装置能够获取第一通信装置获取第一测量值的符号位置的信息，便于在确定第一通信装置与第二通信装置之间的飞行时间时，根据第一通信装置的时钟晶振误差与第二通信装置的时钟晶振误差的关系，将第一测量值转换为第二通信装置对应的测量结果，从而降低时钟漂移误差对定位测量结果的影响，能够提升定位的定位精度。
在已获取两个终端设备的时钟晶振误差之间的关系的情况下，若能够获取终端设备B实际测量的起始时间，终端设备A可以降低这几个间隔符号所引起的时钟漂移误差，从而提高定位的定位精度。
一个可能的实现方式，测量报告1还包括测量值B(譬如，第二测量值)与符号索引B(譬如，第二符号索引)。具体地，第一通信装置向第二通信装置上报的测量报告1可以包括多个测量值与多个符号索引。为便于描述，本申请以测量报告1包括测量值A、符号索引A、测量值B以及符号索引B为例进行描述，但不限定测量报告1包括更多数量的测量值与符号索引等场景。
应理解，第一通信装置上报的多个测量值与多个符号索引能够用于第二通信装置确定第一通信装置的时钟晶振误差与第二通信装置的时钟晶振误差之间的关系。示例性地，第一通信装置在时隙A内的第一个符号与第二个符号分别对第一信号进行测量，分别得到测量值1与测量值2。其中，每个测量值与一个符号索引关联。此时，测量报告1的形式可以如表2所示。
表2
如表2所示，第一通信装置在符号索引0指示的第一个符号对第一信号进行测量，得到测量值1；第一通信装置在符号索引1指示的第二个符号对第一信号进行测量，得到测量值2。
第二通信装置根据第一通装置上报的测量值1、测量值2、符号索引0以及符号索引1确定第一通信装置的时钟晶振误差与第二通信装置的时钟晶振误差之间的关系。
示例性地，假设符号索引1和符号索引2之间的间隔为时间t，测量值1对应的时间为时间t1，测量值2对应的时间为时间t2。第一通信装置的时钟晶振误差为eA，第二通信装置的时钟晶振误差为eB。那么，第一通信装置的时钟晶振误差eA与第二通信装置的时钟晶振误差eB之间的关系为:
其中，对于第二通信装置而言，第二通信装置仅向第一通信装置发送PRS1(为第一信号)，第一通信装置在不同的符号对PRS1进行两次测量，则等同于第二通信装置分别在符号索引1所指示的符号向第一通信装置发送PRS11，在符号索引2所指示的符号向第一通信装置发送PRS12。相应地，第二通信装置需要记录的PRS11与PRS12之间的时间间隔的真实时间等于公式(6)中的左侧表达式，第一通信装置需要记录的PRS11与PRS12之间的时间间隔的真实时间等于公式(6)中的右侧表达式。
由于时钟晶振误差的影响，第二通信装置所记录的PRS11与PRS12之间的误差间隔时间可以等同于t2与t1的差值以及与t的和值。因此，在PRS11与PRS12之间的真实时间间隔相同时，则可以得出公式(6)。
一个可能的实现方式，在S310之前，方法300还包括：
S300a、第二通信装置向第一通信装置发送指示信息1，其用于指示在符号索引A指示的符号获取测量值A，在符号索引B指示的符号获取测量值B。
如此，第一通信装置根据第二通信装置的指示信息1向第二通信装置上报测量值A、符号索引A、测量值B以及符号索引B。如此，便于第二通信装置根据第一通信装置上报的多个测量值与多个符号索引确定第一通信装置的时钟晶振误差与第二通信装置的时钟晶振误差之间的关系。相应地，第二通信装置根据第一通信装置上报的多个测量值与多个符号索引确定第一通信装置的时钟晶振误差与第二 通信装置的时钟晶振误差之间的关系。具体可以见公式(5)，在此不再赘述。
一个可能的实现方式，指示信息1包括：无线资源控制(radio resource control，RRC)、介质访问控制层控制单元(medium access control-control element，MAC CE)或者侧行链路控制信息(side-link control information，SCI)等中的任意一项。其中，指示信息1的作用是用于触发第一通信装置在多个符号位置进行对第一信号的测量。其中，该多个符号的位置可以由第二通信装置通过指示信息1指示。
一个可能的实现方式，指示信息1还包括符号索引A与符号索引B。换言之，第二通信装置指示第一通信装置在符号索引A所指示的符号进行测量并获取测量值A，在符号索引B所指示的符号进行测量并获取测量值B。如此，第一通信装置按照指示信息1携带的符号索引A指示的符号与符号索引B指示的符号分别进行测量，并按照符号索引的顺序依次上报测量值A与测量值B。如此，第一通信装置在第二通信装置指示的符号位置对第一信号进行测量，并得到两个测量值。
可选地，指示信息1携带符号索引A与符号索引B时，测量报告1可以包括符号索引A与符号索引B，也可以不包括符号索引A与符号索引B，本申请对此不做限定。
一个可能的实现方式，在S310之前，方法300还包括：
S300b、第二通信装置向第一通信装置发送信息1(譬如，第一信息)，其用于调度第一资源，第一资源用于第一信号的传输。其中，第一资源包括符号索引A指示的符号。
具体来说，第二通信装置根据资源池的配置确定用于传输第一信号的第一资源，并向第一通信装置发送信息1，其用于指示传输第一信号的第一资源。
一个可能的实现方式，第二通信装置向第一通信装置指示上报多个符号索引以及多个测量值时，第一资源还包括符号索引B指示的符号。如此，便于第一通信装置在符号索引A与符号索引B分别指示的符号位置对第一信号进行测量，得到测量值A与测量值B。
相应地，第二通信装置向第一通信装置发送第一信号。具体地，第二通信装置可以在第一资源向第一通信装置发送第一信号。
应理解，本申请对S300b与S300a之间的先后顺序不做限定。为便于描述，本申请以S300a在S300b之后为例进行描述。
一个可能的实现方式，方法300还包括：
S340a、第一通信装置向第二通信装置发送信息2(譬如，第二信息)，其用于调度第二资源，该第二资源用于第二信号的传输。
相应地，第二通信装置接收来自于第一通信装置发送的信息2，并基于信息2确定第一通信装置向第二通信装置传输第二信号的第二资源。
可以理解的是，S340a发生在S340之前。另外，本申请对S340a的进行顺序与S330的进行顺序之间的先后顺序不做限定。
一个可能的实现方式，测量报告1包括第一结构与第二结构。其中，第一结构用于承载测量值A，第二结构用于承载时隙标识。
一个可能的实现方式，测量报告1中的第一结构为nr-UE-RxTxTimeDiff-r16，第二结构为nr-TimeStamp-r16。其中，第一结构与第二结构的具体形式可以参见现有标准，本申请对此不作赘述。
此外，测量报告1中的符号索引A可以承载于第一结构，即符号索引A承载于nr-UE-RxTxTimeDiff-r16，或者，符号索引A承载于nr-TimeStamp-r16。若测量报告1还包括测量值B与符号索引B，则测量值B承载于第一结构，符号索引B既可以承载于第一结构，也可以承载于第二结构。如此，可以实现与现有的测量报告的兼容。
一个可能的实现方式，第一信号包括多个子信号，譬如，第一信号包括第一子信号与第二子信号。其中，该多个子信号位于相同的时隙之中。
示例性地，第一信号包括第一子信号与第二子信号，第一子信号与第二子信号各自占用不同的时频资源。关于第一子信号与第二子信号的描述可以参见图4。
图4是第一子信号与第二子信号的配置示意图。如图4所示，第一信号占用12个子载波与8个符号。其中，第一子信号占用的时频资源为前4个符号以及12个子载波，第二子信号占用的时频资源为后四个符号以及12个子载波。其中，每个斜杠纹理的方框表示用于传输定位测量信号的时频资源，空白方框表示不用于传输定位测量信号的时频资源。
具体来说，第一信号采用多个子信号的配置形式时，本申请支持第一通信装置在向第二通信装置上报测量报告1时，测量报告1包括每个子信号分别对应的测量值。其中，测量报告1还可以包括测量值对应的符号索引和/或子信号索引。
一个可能的实现方式中，若第一信号满足疏型(comb)4的配置以及第一信号所占用的符号数量为8，则第一子信号包括前四个符号，第二子信号包括后四个符号。其中，关于comb4的描述可以参见现有技术，本申请对此不再赘述。
一个可能的实现方式，本申请支持测量报告1通过按顺序填放每个子信号分别对应的测量值的方式实现不包括符号索引和/或子信号索引。如此，可以节约信令开销。
