Description

一种测量上报方法及装置 技术领域
本申请涉及通信技术领域，特别涉及一种测量上报方法及装置。
背景技术
传统的蜂窝网定位，基于终端对下行参考信号进行测量，或者基站对上行参考信号进行测量，并将测量结果上报给定位服务器，由定位服务器根据测量结果以及基站位置确定出终端位置。
目前终端或者基站的测量上报过程通常为物理层测量，高层上报，其中，物理层在对周期性的参考信号进行物理层测量后，将多次物理层的测量量对应的值通过滤波合并成一个值上报给高层，高层收到物理层上报之后，进行层3滤波，并将层3滤波的结果作为高层上报量反馈给定位服务器。例如，测量量为到达时间(time of arrival，TOA)，参考信号到达时间差(reference signal time difference，RSTD)，终端接收参考信号-发送参考信号时间差(UE Rx–Tx time difference)；或者，所述定位信息请求消息中包括以下一项或多项测量量：上行相对到达时间(uplink relative time of arrival，UL-RTOA)，基站接收参考信号-发送参考信号时间差(gNB Rx–Tx time difference)，水平/垂直到达角(azimuth/zenith angle of arrival，AoA/ZoA)。
但是，在终端移动过程中，终端测量的测量量对应的值(可以称为测量值)可能会随着位置的变化发生变化，而经过滤波输出单个值的方式，会将测量值的变化平滑掉，从而会丢失上报周期内测量量变化的信息。同理，终端移动或者终端的定时提前(timing advance，TA)发生变化时发送上行参考信号会导致上行参考信号到达基站的时间发生变化，从而导致测量值发生变化，而经过滤波输出单个值的方式，会将测量值的变化平滑掉，从而会丢失上报周期内测量值变化的信息。

为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
本申请提供的测量上报方法可以应用于各类通信系统中，例如，可以是物联网(internet of things，IoT)系统、窄带物联网(narrow band internet of things，NB-IoT)系统、长期演进(long term evolution，LTE)系统，也可以是第五代(5G)通信系统，还可以是LTE与5G混合架构、也可以是5G新无线(new radio，NR)系统，以及未来通信发展中出现的新的通信系统等。
示例性的，图1示出本申请适用的一种通信系统架构示意图，该通信系统可以包括核心网、无线接入网(next-generation radio access network，NG-RAN)以及终端，其中，核心网可以包括接入和移动性管理功能(access and mobility management function，AMF)、定位管理功能(location management function，LMF)等功能，其中，AMF可以实现网关等 功能，LMF可以实现定位中心等功能，当然核心网中也可以包括其他网元，这里不再一一列举。AMF和LMF之间可以通过NLs接口连接。NG-RAN可以包括一个或多个网络设备，网络设备可以但不限于为ng-eNB、gNB等等，其中ng-eNB为接入5G核心网的LTE基站，gNB为接入5G核心网的5G基站。终端包括一个或多个用户设备(user equipment，UE)。无线接入网可以通过NG-C接口经由AMF连接到核心网，终端通过LTE-Uu经由ng-eNB连接到无线接入网，也可以通过NR-Uu经由ng-eNB和gNB连接到无线接入网。
图2示出本申请适用的另一种通信系统架构示意图，该通信系统中网络设备可以包含定位管理组件(location management component，LMC)，LMC可以实现LMF的一部分功能，从而可以不需要经由AMF引入5G核心网。
应理解，图1和图2仅是一种示例性说明，并不对本申请适用的通信系统所包括网元的类型、数量、连接方式等进行具体限定。
本申请实施例中涉及的LMF是一种部署在核心网中为UE提供定位功能的装置或组件。
本申请实施例中涉及的LMC是LMF的部分功能组件，可以集成在NG-RAN侧的gNB上。
本申请实施例中涉及的终端，是用户侧的一种用于接收或发射信号的实体。终端可以是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。终端也可以是连接到无线调制解调器的其他处理设备。终端可以通过无线接入网(radio access network，RAN)与一个或多个核心网进行通信。终端也可以称为无线终端、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment，UE)等等。终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，终端还可以是个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、等设备。常见的终端例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等，但本申请实施例不限于此。
本申请实施例中所涉及的网络设备，是网络侧的一种用于发射和/或接收信号的实体，可以用于将收到的空中帧与网络协议(internet protocol，IP)分组进行相互转换，作为终端与接入网的其余部分之间的路由器，其中接入网的其余部分可以包括IP网络等。网络设备还可以协调对空中接口的属性管理。例如，网络设备可以是LTE中的演进型基站(evolutional Node B，eNB或e-NodeB)，eNB是一种部署在无线接入网中满足4G标准的为UE提供无线通信功能的装置。网络设备还可以是新无线控制器(new radio controller，NR controller)，可以是5G系统中的gNode B(gNB)，可以是集中式网元(centralized unit)，可以是新无线基站，可以是射频拉远模块，可以是微基站(也称为小站)，可以是中继(relay)，可以是分布式网元(distributed unit)，可以是各种形式的宏基站，可以是传输接收点(transmission reception point，TRP)、传输测量功能(transmission measurement function，TMF)或传输点(transmission point，TP)或者任何其它无线接入设备，或者下一代通信中的基站，但本申请实施例不限于此。
传统的蜂窝网定位，基于终端对下行参考信号(如定位参考信号(positioning reference signal，PRS))进行测量，或者基站对上行参考信号(如探测参考信号(sounding reference signal，SRS))进行测量，并将测量结果上报给定位服务器，由定位服务器根据测量结果以及基站位置确定出终端位置。
其中，对于下行到达时间差(downlink time difference of arrival，DL-TDOA)或者观测到达时间差(observed time difference of arrival，OTDOA)定位，终端对下行参考信号PRS测量RSTD，将RSTD上报给定位服务器。
对于上行到达时间差(uplink time difference of arrival，UL-TDOA或者UTDOA)定位，基站对上行参考信号SRS测量UL-RTOA，将UL-RTOA上报给定位服务器。
对于多小区(Multi-cell)往返时间(round trip time，RTT)定位，终端对PRS测量UE Rx–Tx time difference，基站对SRS测量gNB Rx–Tx time difference，分别将UE Rx–Tx time difference和gNB Rx–Tx time difference上报给定位服务器。从而定位服务器可以基于UE Rx–Tx time difference以及gNB Rx–Tx time difference确定终端与基站之间的往返时间，从而根据往返时间确定终端的位置。
目前终端或者基站的测量上报过程通常为物理层测量，高层上报，其中，物理层在对周期性的参考信号进行物理层测量后，将多次物理层的测量量对应的测量值通过滤波合并成一个测量值上报给高层，高层收到物理层上报之后，进行层3滤波，并将层3滤波的结果作为高层上报量反馈给定位服务器。如图3所示。
一般而言，以下行为例，终端对于周期性发送的物理层参考信号进行物理层测量，多次物理层的测量量对应的值合并成一次测量由终端物理层上报给终端高层。终端高层收到物理层上报之后，进行层3滤波，例如可以通过形式如F n＝(1–a)*F n-1+a*M n的一阶无限脉冲响应(infinite impulse response，IIR)滤波器平滑历史滤波结果和最新的一次物理层上报的测量值，这里a可以等于1/2 (ki/4)，ki为正数。终端高层将层3滤波的结果作为高层上报量反馈给定位服务器。
在LTE中OTDOA的终端基于PRS测量RSTD，PRS的周期可以为5ms、10ms、20ms、40ms、80ms、160ms、320ms、640ms、1280ms，而OTDOA上报周期可以配置为0.25s、0.5s、1s、2s、4s、8s、10s、16s、20s、32s、64s。可见，针对某个小区，在一个OTDOA上报周期内终端进行多次PRS测量，从而得到多个RSTD，例如，PRS的周期为10ms，OTDOA上报周期为0.5s时，在一个OTDOA上报周期内终端进行50次PRS测量，得到50个RSTD。但是，在每个OTDOA上报周期内终端针对该小区仅上报一个RSTD。
但是，在终端移动过程中，终端测量的RSTD可能会随着位置的变化发生变化，而经过滤波输出单个值的方式，会将RSTD的变化平滑掉，从而会丢失上报周期内RSTD变化的信息。
LTE中UTDOA的定位管理单元(location management unit，LMU)基于SRS测量UL-RTOA，其中，SRS的周期可以为2ms、5ms、10ms、20ms、40ms、80ms、160ms、320ms。UTDOA上报时，根据配置的SRS带宽，需要每M个SRS周期，上报满足一定精度要求的UL-RTOA，如表1所示。以LMU接收单载波的单个UE为例，最小SRS传输次数(Minimum number of SRS transmissions)对应了M的最小值。例如SRS带宽为60个RB时，LMU需要每5次测量获取精度为要求为6Ts的UL-RTOA，并上报给定位中心。同样，每次上报，LMU只会对某个UE的每个上行载波上报一个UL-RTOA。
表1
Figure PCTCN2019105776-appb-000001
其中，加性高斯白噪声(additive white gaussian noise，AWGN)、EPA5、ETU30为信道模型，SRS bandwidth为SRS的带宽，Minimum number of SRS transmissions为UTDOA上报时传输的SRS次数，90％RTOA为上报的UL-RTOA的精度。
终端移动或者终端的定时提前(timing advance，TA)发生变化时发送SRS会导致SRS到达基站的时间发生变化，从而导致UL-RTOA发生变化，而经过滤波输出单个值的方式，会将UL-RTOA的变化平滑掉，从而会丢失上报周期内UL-RTOA变化的信息。并且如果有TA变化的话，会导致上报UL-RTOA发生错误。
基于此，本申请实施例提供一种测量上报方法及装置。其中，方法和装置是基于同一技术构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
应理解，本申请实施例中“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“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的情况，其中A、B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一(项)个”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a、b或c中的至少一项(个)，可以表示：a，b，c，a和b，a和c，b和c，或a、b和c，其中a、b、c可以是单个，也可以是多个。
另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
本申请实施例中，定位设备可以是LMF网元，例如，参阅如图1所示，也可以是集中在gNB内的LMC(也可以称为RAN-LMC)，例如参阅图2所示。RAN-LMC对应一个基站，或者RAN-LMC对应一个定位基站。
下面结合附图对本申请实施例提供的测量上报方法进行具体说明。
实施例一：
参阅图4所示，本申请实施例针对终端提供一种测量上报方法，下面针对一个测量上报周期对该方法进行说明。该方法包括：
S401，在一个测量上报周期内，终端接收来自一个或多个基站在N个参考信号周期发送的N个参考信号。其中，N为大于1的整数。
应理解的，本申请实施例涉及的基站也可以是定位基站。
示例性的，参考信号可以为PRS。下面以PRS为例进行说明。
一种示例性说明中，PRS的周期可以为5ms、10ms、20ms、40ms、80ms、160ms、320ms、640ms、1280ms等等，而测量上报周期可以配置为0.25s、0.5s、1s、2s、4s、8s、10s、16s、20s、32s、64s等等。可见，一个测量上报周期内包括多个PRS周期，N可以等于测量上报周期所包括PRS数量，例如，PRS的周期为10ms，OTDOA上报周期为0.5s时，在一个OTDOA上报周期内终端可以进行50次PRS测量，N可以等于50。
可选的，在步骤S401之前，可以执行步骤S402。
S402，定位设备可以向终端发送来自一个或多个基站的所述下行参考信号配置。相应的，终端可以接收所述下行参考信号配置。示例性的，下行参考信号配置可以是PRS配置。例如，PRS配置包括如下一项或多项信息：PRS的发送周期、PRS时频资源、PRS序列、准共址(QCL)等。
S403，在该测量上报周期内，终端测量所述一个或多个基站发送的N个PRS，得到N个测量值。
其中，每个测量值可以包括以下一项或多项测量量：TOA、RSTD、UE Rx–Tx time difference。
一种实现方式中，测量值中包括的测量量可以是定位设备指示的。例如，在步骤401之前，可以执行步骤S404。
S404，定位设备还可以向终端发送定位信息请求消息。相应的，终端可以接收定位设备发送的定位信息请求消息。可选地，定位信息请求消息中可以包括以下一项或多项测量量：TOA、RSTD、UE Rx–Tx time difference。
需要说明的是，步骤S402与步骤S404没有严格的执行顺序，可以向执行S402再执行S404，也可以先执行S404再执行步骤S402，还可以同时执行S402和S404，这里不做具体限定。
另一种实现方式中，测量量也可以是终端与定位设备协商确定的。其中，终端与定位设备协商确定的测量量可以是TOA、RSTD、UE Rx–Tx time difference中的一个或多个，也可以是其他测量量。
再一种实现方式中，测量量还可以是协议规定的。
S405，终端可以在该N个测量值中确定M个测量值，其中，M可以小于或等于N。
一种可能的实施方式中，该M的取值可以是定位设备指示的，例如，定位设备发送的定位信息请求消息中可以包括该M的取值。
在一些实施例中，终端可以在N个测量值中均匀取值。例如，N等于100，M等于10时，可以每间隔10个PRS周期取一个测量值，因此，M个测量值可以包括第10个PRS周期测量的测量值、第20个PRS周期测量的测量值、第30个PRS周期测量的测量值、……，第100个PRS周期测量的测量值。
另一些实施例中，终端也可以将N个测量值分为M组，每组测量值可以确定一个测量值。例如，可以采用图3所示的滤波方法确定每组测量值对应的一个测量值。又例如，可以将每组测量值的平均值作为该组测量值对应的测量值。再例如，可以将每组测量值的加权和作为该组测量值对应的测量值。
再一些实施例中，终端也可以在N个测量值取M个连续的测量值，如，N等于100，M等于10时，可以取最后10个测量值，即第91个测量值～第100个测量值，或者取第85个测量值～第94个测量值，或者取第1个测量值～第10个测量值，或者取第13个测量值～第22个测量值，等等。
上述方式通过减少上报的测量值的数量，可以节省终端的系统开销。
一种实现方式中，M可以等于N，这种方式中，终端在得到N个测量值后无需进行选择，即可以不执行S405。
S406，终端向定位设备上报测量报告，其中，测量报告包括M个测量结果。
其中，M个测量结果满足以下任一规则：
第i个测量结果是所述M个测量值中的第i个测量值；
或者，第i个测量结果是所述M个测量值中的第i个测量值相对于第1个测量值的变化量；
或者，第i个测量结果是所述M个测量值中的第i个测量值相对于第(i-1)个测量值的变化量；
或者，第i个测量结果是所述M个测量值的所述第i个测量值相对于第M个测量值的变化量；
所述i大于1小于或等于所述M。
示例性地，对于RSTD的上报，M个测量结果可以包括针对邻小区测量的RSTD值，具体来说，M个测量结果可以包括如下信息中的一个或多个：
R(i)，其中，i＝1，2，3，4，……，M；
R 1(i)，其中，i＝1时，R 1(1)＝R(1)，i＝2，3，4，……，M时，R 1(i)＝R(i)-R(1)；
R 2(i)，其中，i＝1时，R 2(1)＝R(1)，i＝2，3，4，……，M时，R 2(i)＝R(i)-R(i-1)；
R 3(i)，其中，i＝M时，R 3(M)＝R(M)，i＝1，2，3，4，……，M-1时，R 3(i)＝R(i)-R(M)。
其中，R(i)为M个测量值中第i个测量值包括的RSTD值。
举例说明，假设N等于10，M等于5，5个测量结果分别可以是第1个PRS周期上测量的测量值、第3个PRS周期上测量的测量值、第5个PRS周期上测量的测量值、第7个PRS周期上测量的测量值、第9个PRS周期上测量的测量值。因此，M个测量结果可以包括如下信息中的一个或多个：

示例性地，M个测量结果还可以包括针对参考小区测量的TOA值，具体来说，M个测量结果还可以包括如下信息中的一个或多个：
T 1(i)，其中，i＝1时，T 1(1)＝T(1)，i＝2，3，4，……，M时，T 1(i)＝T(i)-T(1)；
T 2(i)，其中，i＝1时，T 2(1)＝T(1)，i＝2，3，4，……，M时，T 2(i)＝T(i)-T(i-1)；
T 3(i)，其中，i＝M时，T 3(M)＝T(M)，i＝1，2，3，4，……，M-1时，T 3(i)＝T(i)-T(M)。
其中，T(i)为M个测量值中第i个测量值包括的TOA值。当M等于N时，T(i)也可以理解为在第i个PRS周期上测到的TOA值。
以上述N等于10，M等于5为例，M个测量结果还可以包括如下信息中的一个或多个：
第1个PRS周期上测量的TOA值，第3个PRS周期上测量的TOA值相对于第1个PRS周期上测量的TOA值的变化量，第5个PRS周期上测量的TOA值相对于第1个PRS周期上测量的TOA值的变化量，第7个PRS周期上测量的TOA值相对于第1个PRS周期上测量的TOA值的变化量，第9个PRS周期上测量的TOA值相对于第1个PRS周期上测量的TOA值的变化量；

第9个PRS周期上测量的TOA值，第1个PRS周期上测量的TOA值相对于第9个PRS周期上测量的TOA值的变化量，第3个PRS周期上测量的TOA值相对于第9个PRS周期上测量的TOA值的变化量，第5个PRS周期上测量的TOA值相对于第9个PRS周期上测量的TOA值的变化量，第7个PRS周期上测量的TOA值相对于第9个PRS周期上测量的TOA值的变化量。
对于UE Rx–Tx time difference的上报，M个测量结果可以包括针对每个小区测量的UE Rx–Tx time difference值，具体来说，M个测量结果可以包括如下信息中的一个或多个：
D(i)，其中，i＝1，2，3，4，……，M；
D 1(i)，其中，当i等于1时，D 1(1)＝D(1)，i＝2，3，4，……，M时，D 1(i)＝D(i)-D(1)；
D 2(i)，其中，当i等于1时，D 2(1)＝D(1)，i＝2，3，4，……，M时，D 2(i)＝D(i)-D(i-1)；
D 3(i)，其中，当i等于M时，D 3(M)＝D(M)，i＝1，2，3，4，……，M-1时，D 3(i)＝D(i)-D(M)。
其中，D(i)为M个测量值中第i个测量值包括的UE Rx–Tx time difference值。
UE Rx–Tx time difference的上报方式，与RSTD的上报方式类似，相似之处不再赘述。
一种实现方式中，M个测量结果还可以包括终端接收N个PRS的N个时间戳。
示例性的，时间戳的类型可以为PRS周期的序号，或者，PRS周期对应的SFN号，或者，PRS周期对应的SFN号以及PRS所在子帧的子帧号，或者，PRS周期对应的SFN号以及PRS所在时隙的时隙号。
在一些实施例中，时间戳的可以是定位设备指示的，例如，定位设备发送的定位信息请求消息可以包括时间戳的类型。
一种可能的实现方式中，定位信息请求消息可以指示每次测量的时间戳类型。
在另一些实施例中，时间戳的类型也可以是终端与定位设备协商的。
还有一些实施例中，时间戳的类型也可以是协议规定的。
一种可能的实施方式中，每个测量结果可以对应一个时间戳，也可以是每个测量结果中包括的每个信息对应一个时间戳。以第i个测量结果包括R(i)、T 1(i)、D 2(i)为例进行说明，该第i个测量结果可以对应一个时间戳，或者，R(i)、T 1(i)、D 2(i)分别对应一个时间戳。
进一步的，当R(i)、T 1(i)、D 2(i)分别对应一个时间戳时，R(i)的时间戳可以与R(i)一起上报，T 1(i)的时间戳可以与T 1(i)一起上报，D 2(i)的时间戳可以与D 2(i)一起上报。
上述方式通过上报时间戳，可以使得定位设备估计终端的速度，从而可以更准确的获取终端的位置信息。
本申请实施例中，终端在单次上报中携带多个测量值，从而可以使定位设备确定上报周期内测量值变化情况，从而可以提高终端定位的准确性。
可选地，终端还可以向定位设备上报时间戳，通过在单次上报中携带多个测量结果以及时间戳，使得定位设备可以跟踪终端移动，实现诸如终端速度预测、轨迹构建等定位效果。
参阅图5所示，本申请实施例针对网络设备提供一种测量上报方法，下面针对一个测量上报周期对该方法进行说明。该方法包括：
S501，在一个测量上报周期内，基站接收终端在N个参考信号周期发送的N个参考信号。其中，N为大于1的整数。
应理解的，本申请实施例涉及的基站也可以是定位基站。
示例性的，参考信号可以为SRS。下面以SRS为例进行说明。
一种示例性说明中，SRS的周期可以为2ms、5ms、10ms、20ms、40ms、80ms、160ms、320ms等等，根据配置的SRS带宽，可以确定每N个SRS周期上报一次测量报告，N个SRS周期可以视为一个测量上报周期。例如，根据表1所示，SRS带宽为60个RB时，LMU需要每5次测量获取精度为要求为6Ts的UL-RTOA，即每5个SRS周期上报一次测量报告。
一种实现方式中，在步骤S501之前，可以执行步骤S502和S503。

S504，在该测量上报周期内，基站对终端发送的N个SRS进行测量，得到N个测量 值。
其中，每个测量值可以对应以下一项或多项测量量：UL-RTOA、gNB Rx–Tx time difference、AoA/ZoA。
一种实现方式中，测量值中对应的测量量可以是定位设备指示的。例如，在步骤501之前，可以执行步骤S505。
S505，定位设备还可以向基站发送定位信息请求消息。相应的，基站可以接收定位设备发送的定位信息请求消息。可选地，定位信息请求消息中可以包括以下一项或多项测量量：UL-RTOA、gNB Rx–Tx time difference、AoA/ZoA。
需要说明的是，步骤S503与步骤S505没有严格的执行顺序，可以向执行S503再执行S505，也可以先执行S505再执行步骤S503，还可以同时执行S503和S505，这里不做具体限定。
另一种实现方式中，测量量也可以是基站与定位设备协商确定的。
再一种实现方式中，测量量还可以是协议规定的。
S506，基站可以在该N个测量值中确定M个测量值，其中，M可以小于或等于N。
一种可能的实施方式中，该M的取值可以是定位设备指示的，例如，定位设备发送的定位信息请求消息中可以包括该M的取值。
其中，基站在N个测量值中确定M个测量值的方法，与上述实施例一中终端在N个测量值中确定M个测量值的方法类似，具体可以参阅上文，这里不再重复赘述。
上述方式通过减少上报的测量值的数量，可以节省基站的系统开销。
一种实现方式中，M可以等于N，这种方式中，纪姿含在得到N个测量值后无需进行选择，即可以不执行S506。
S507，基站向定位设备上报测量报告，其中，测量报告包括M个测量结果。
可选地，M个测量结果满足以下任一规则:
第i个测量结果是所述M个测量值中的第i个测量值；
或者，第i个测量结果是所述M个测量值中的第i个测量值相对于第1个测量值的变化量；

一种实现方式中，M个测量结果还可以包括基站接收N个SRS的N个时间戳。
其中，时间戳的类型以及上报方法，具体可以参阅上述实施例一中时间戳的相关描述，这里不再赘述。
在一些实施例中，时间戳的类型可以是定位设备指示的，例如，定位设备发送的定位信息请求消息可以包括时间戳的类型。
在另一些实施例中，时间戳的类型也可以是基站与定位设备协商的。
还有一些实施例中，时间戳的类型也可以是协议规定的。
本申请实施例中，基站在单次上报中携带多个测量结果，从而可以使定位设备确定上报周期内测量值变化情况，从而可以提高终端定位的准确性。
