Description

一种定位信息的确定方法及通信装置 技术领域
本申请涉及通信技术领域，特别涉及一种定位信息的确定方法及通信装置。
背景技术
在现有的定位方法中，定位设备将终端设备的所有天线当作同一位置的一个质点来进行定位，并将确定的天线位置作为终端设备的位置。当定位精度在数米级时，终端设备的尺寸相对于定位精度而言较小，可以将终端设备的所有天线当作一个质点来进行定位，终端设备的多个天线之间的距离在这样的定位精度下可以忽略。
然而在3GPP Rel-17的IIoT工业物联网(industrial internet of things，IIoT)中，对终端设备的定位精度要求小于0.2m(米)，即对终端设备的定位误差应当小于0.2m。在工业物联网场景下，往往终端设备(例如自动车辆、自动货船等)的尺寸以及终端设备的多个天线之间的距离均大于定位精度。在这种场景下，若将终端设备的所有天线当成一个质点来进行定位，会导致确定的终端设备的位置信息的近似误差较大，并且将终端设备的所有天线当成一个质点也无法确定终端设备的朝向或姿态等信息。因此，如何准确地确定的终端设备的定位信息(如位置信息、朝向信息或姿态信息等)是5G及其下一代移动通信系统亟待解决的问题。
发明内容

本申请实施例中，终端设备支持多个天线标识对应的天线。其中，终端设备的一个天线标识可用于标识一个天线或一组天线，即一个天线标识可以对应一个天线或一组天线。例如，如果天线1和天线2在终端设备部署的位置很远，则可通过不同的天线标识来标识天线1和天线2。如果天线1和天线2在终端设备部署的位置很近，则可以将天线1和天线2看做一个天线，使用同一个天线标识对天线1和天线2进行标识。图1以终端设备支持天线标识1对应的天线1～天线标识4对应的天线4为例进行说明。
本申请实施例中涉及的终端设备，是用户侧的一种用于接收或发射信号的实体。终端设备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。终端设备也可以是连接到无线调制解调器的其他处理设备。终端设备可以与无线接入网(radio access network，RAN)进行通信。终端设备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。终端设备可以是移动终端，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，终端设备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。常见的终端设备例如包括：汽车、无人机、机械臂、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。

本申请实施例具体提供了一种下行的定位信息的确定方法和一种上行的定位信息的确定方法。所谓的下行的定位信息的确定方法指：由接入网设备向终端设备发送下行参考信号。终端设备对下行参考信号进行测量，并将测量结果发送至定位管理设备，由定位管理设备基于测量结果确定终端设备的定位信息。所谓的上行的定位信息的确定方法指：由终端设备向接入网设备发送上行参考信号，接入网设备对上行参考信号进行测量，并将测量结果发送至定位管理设备。由定位管理设备根据测量结果确定终端设备的定位信息。
为了更好地理解本申请提供的方案，下面对本申请实施例涉及的相关术语进行介绍：
参考信号(reference signal，RS)：即导频信号，是由发射端发送给接收端的，用于信道估计或信道探测的一种已知信号。参考信号可以分为上行参考信号和下行参考信号。例如，终端设备向网络侧的接入网设备(如基站)发送的参考信号为上行参考信号，接入网设备向终端设备发送的参考信号为下行参考信号。
参考信号到达时间差(reference signal time difference，RSTD)：终端设备对下行参考信号进行测量，得到的测量结果。终端设备可将测量得到的RSTD上报给定位管理设备，由定位管理设备基于RSTD确定终端设备的定位信息。可选的，在本申请提供的下行的定位信息的确定方法中，终端设备可通过多个天线标识对应的天线来测量RSTD。其中，终端设备的某个天线标识对应的天线测量的RSTD＝T uerx2–T uerx1。T uerx2为该天线标识对应的天线从接入网设备2接收到下行参考信号b的开始时间，T uerx1为该天线标识对应的天线从接入网设备1接收到下行参考信号a的开始时间。下行参考信号a为该天线标识对应的天线从接入网设备1接收的与下行参考信号b的开始接收时间最接近的参考信号。接入网设备1为参考设备。
举例来说，如图2所示，终端设备具有天线标识1对应的天线1和天线标识2对应的天线2。接入网设备1为参考设备。天线1从接入网设备2接收到下行参考信号2的开始时间为t2，天线1从接入网设备1接收到下行参考信号1的开始时间为t1。下行参考信号1为天线1从接入网设备1接收的与下行参考信号2的开始接收时间最接近的参考信号。因此，天线1测量的RSTD1＝t2-t1。同理，天线2从接入网设备2接收到下行参考信号4的开始时间为t4，天线2从接入网设备1接收到下行参考信号3的开始时间为t3。下行参考信号3为天线2从接入网设 备1接收的与下行参考信号4的开始接收时间最接近的参考信号。因此，天线2测量的RSTD2＝t4-t3。
参考信号接收功率(reference signal received power，RSRP)：终端设备对接入网设备发送的下行参考信号进行测量，得到的测量结果。终端设备可将测量得到的RSRP上报给定位管理设备。由定位管理设备基于RSRP得到DL-AOD，并基于DL-AOD确定终端设备的定位信息。其中，DL-AOD是指接入网设备向终端设备的天线发送的参考信号离开接入网设备时，与某一方向(如：水平面的某个方向或水平面的法线方向)之间的夹角。可选的，在本申请提供的下行的定位信息的确定方法中，终端设备可通过多个天线标识对应的天线来测量RSRP。例如，如图3所示，终端设备具有天线标识1对应的天线1和天线标识2对应的天线2。天线1对接入网设备发送的一个或多个下行参考信号进行测量得到RSRP11、RSRP12、…、RSRP1M。天线2对接入网设备发送的下行参考信号进行测量得到RSRP21、RSRP22、…RSRP2N。这里M可以等于N，也可以不等于N，M≥1，N≥1。终端设备上报RSRP11、RSRP12、…、RSRP1M和RSRP21、RSRP22、…、RSRP2N至定位管理设备之后，定位管理设备可以基于RSRP11、RSRP12、…、RSRP1M得到DL-AOD1，并RSRP21、RSRP22、…、RSRP2N得到DL-AOD2。定位管理设备可基于DL-AOD1和DL-AOD2确定终端设备的定位信息。
同步信号参考信号接收功率(synchronization signal-reference signal received power，SS-RSRP)/同步信号参考信号接收质量(synchronization signal-reference signal received quality，SS-RSRQ)/同步信号信号与干扰加噪声比(synchronization signal-signal to interference plus noise ratio，SS-SINR)：终端设备对接入网设备发送的下行参考信号进行测量，得到的测量结果。终端设备可将测量得到的SS-RSRP/SS-RSRQ/SS-SINR上报给定位管理设备，由定位管理设备基于SS-RSRP/SS-RSRQ/SS-SINR确定终端设备的定位信息。可选的，在本申请提供的下行的定位信息的确定方法中，终端设备可通过多个天线标识对应的天线来测量SS-RSRP/SS-RSRQ/SS-SINR。
上行链路相对到达时间(uplink relative Time of arrival，UL-RTOA)：接入网设备对终端设备发送的上行参考信号进行测量，得到的测量结果。接入网设备可将UL-RTOA上报给定位管理设备，由定位管理设备基于UL-RTOA确定终端设备的定位信息。可选的，在本申请提供的上行的定位信息的确定方法中，终端设备可通过多个天线标识对应的天线发送上行参考信号。其中，接入网设备测量某个天线标识对应的天线所发送的上行参考信号得到的UL-RTOA＝T gnbrx1-T reference。该T gnbrx1为接入网设备接收到该天线发送的上行参考信号的开始时间。该T reference为接入网设备的参考时间。举例来说，如图4所示，终端设备具有天线标识1对应的天线1和天线标识2对应的天线2。天线1发送上行参考信号1。天线2发送上行参考信号2。接入网设备接收到上行参考信号1的开始时间为t1，接入网设备接收到上行参考信号2的开始时间为t2，接入网设备的参考时间为t0。接入网设备对天线1发送的上行参考信号1进行测量，得到UL-RTOA1，UL-RTOA1＝t1-t0，接入网设备对天线2发送的上行参考信号2进行测量，得到UL-RTOA2，UL-RTOA2＝t2-t0。
上行链路到达角(uplink angle of arrival，UL-AOA)：接入网设备对终端设备发送的上行参考信号进行测量，得到的测量结果。接入网设备可将UL-AOA上报给定位管理设备，由定位管理设备基于UL-AOA确定终端设备的定位信息。可选的，在本申请提供的上行的定位信息的确定方法中，终端设备可通过多个天线标识对应的天线发送上行参考信号。 UL-AOA为终端设备的天线发送的参考信号到达接入网设备时，与某一方向(如：水平面的某个方向或水平面的法线方向)之间的夹角。例如，如图5所示，终端设备具有天线标识1对应的天线1和天线标识2对应的天线2。接入网设备对天线1发送的上行参考信号进行测量，得到UL-AOA1。接入网设备对天线2发送的上行参考信号进行测量，得到UL-AOA2。
上行链路垂直到达角(uplink zenith of arrival，UL-ZOA)：接入网设备对终端设备发送的上行参考信号进行测量，得到的测量结果。接入网设备可将UL-ZOA上报给定位管理设备，由定位管理设备基于UL-ZOA确定终端设备的定位信息。可选的，在本申请提供的上行的定位信息的确定方法中，终端设备可通过多个天线标识对应的天线发送上行参考信号。UL-ZOA为终端设备的天线发送的参考信号到达接入网设备时，与垂直方向之间的夹角。例如，如图6所示，终端设备具有天线标识1对应的天线1和天线标识2对应的天线2。接入网设备对天线1发送的上行参考信号进行测量，得到UL-ZOA1。接入网设备对天线2发送的上行参考信号进行测量，得到UL-ZOA2。
多种往返时间(multi-round trip time，Multi-RTT)定位技术：终端设备对接入网设备发送的下行参考信号进行测量，得到用户设备接收-发送时间差(UE-RxTxTimeDiff，UE Rx–Tx time difference)，并将测量结果上报给定位管理设备。UE-RxTxTimeDiff＝T uerx–T uetx。T uerx为终端设备接收下行参考信号的时间，T uetx为终端设备发送上行参考信号的时间。接入网设备对终端设备发送的上行参考信号测量gNB接收-发送时间差(gNB-RxTxTimeDiff，gNB Rx–Tx time difference)，并将测量结果上报给定位管理设备。gNB-RxTxTimeDiff＝T gnbrx–T gnbtx。T gnbrx为接入网设备接收上行参考信号的时间，T gnbtx为接入网设备发送下行参考信号的时间。定位管理设备基于UE-RxTxTimeDiff和gNB-RxTxTimeDiff确定终端设备的定位信息。可选的，在本申请提供的下行的定位信息的确定方法中，终端设备可通过多个天线标识对应的天线测量下行参考信号，得到每个天线标识对应的UE-RxTxTimeDiff。在本申请提供的上行的定位信息的确定方法中，终端设备可通过多个天线标识对应的天线发送上行参考信号，接入网设备得到每个上行参考信号资源对应的gNB-RxTxTimeDiff。定位管理设备根据上行信号资源与天线标识的对应关系得到每个天线标识对应的gNB-RxTxTimeDiff。

请参见图9，图9是本申请实施例提供的一种下行的定位信息的确定方法的流程示意图。如图9所示，该下行的定位信息的确定方法包括如下步骤901～步骤905。图9所示的方法执行主语可以为终端设备、接入网设备和定位管理设备，或主语可以为终端设备中的芯片、接入网设备中的芯片和接入网设备中的芯片中的芯片。图9以终端设备、接入网设备和定位管理设备为方法的执行主体为例进行说明。本申请实施例的其他附图所示的定位信息的 确定方法的执行主语同理，后文不再赘述。其中：
901、终端设备向定位管理设备发送第一信息，该第一信息包括终端设备的多个天线标识以及该多个天线标识中每个天线标识对应的天线局部坐标。相应地，定位管理设备可以接收终端设备发送的该第一信息。
其中，关于天线标识的描述可参见上述系统架构中对天线标识的描述，在此不赘述。天线局部坐标是指局部坐标系中的坐标。该局部坐标系可以是以终端设备的某一点为原点的二维坐标系或三维坐标系。例如，该局部坐标系可以是以终端设备的中心为原点的二维坐标系或三维坐标系。
其中，第一信息中包括的多个天线标识可以是终端设备的部分天线标识或所有天线标识。举例来说，终端设备包括天线标识1对应的天线1～天线标识4对应的天线4。其中，天线标识1＝0，天线1的局部坐标为(-0.5,0.5)。天线标识2＝1，天线2的局部坐标为(0.5,-0.5)。天线标识3＝2，天线3的局部坐标为(-0.5,-0.5)。天线标识4＝3，天线4的局部坐标为(0.5,-0.5)。第一信息中可以包括：{天线标识1＝0，天线1的局部坐标＝(-0.5,0.5)}、{天线标识2＝1，天线2的局部坐标＝(0.5,-0.5)}、{天线标识3＝2，天线3的局部坐标＝(-0.5,-0.5)}和{天线标识4＝3，天线4的局部坐标＝(0.5,-0.5)}。或者，第一信息中包括天线标识1～天线标识4中的多个天线标识，但不包括天线标识1～天线标识4中的所有天线标识。例如，第一信息中包括：{天线标识1＝0，天线1的局部坐标＝(-0.5,0.5)}和{天线标识2＝1，天线2的局部坐标＝(0.5,-0.5)}。可见，第一信息中隐含了天线标识与天线的局部坐标的对应关系。定位管理设备接收第一信息之后，就能基于该第一信息确定天线标识与天线的局部坐标的对应关系。
在一种可能的实现中，第一信息中还包括终端设备的参考点的局部坐标和/或参考点对应的终端设备的天线标识。其中，终端设备的参考点的位置用于表征终端设备的位置，即终端设备的绝对坐标为终端设备的参考点的绝对坐标。通过实施该可能的实现方式，定位管理设备在获取终端设备的参考点的局部坐标和/或参考点对应的终端设备的天线标识之后，就可以基于终端设备的参考点的局部坐标和/或参考点对应的终端设备的天线标识确定终端设备的参考点的绝对坐标，进而确定终端设备的绝对坐标。
可选的，终端设备的参考点可以是终端设备的中心位置，或者为与终端设备的中心位置之间的距离小于预设距离的位置。
可选的，当终端设备的参考点为终端设备的天线时，第一信息中还包括参考点对应的终端设备的天线标识。在这种场景下，第一信息中可包括终端设备的参考点的局部坐标，也可不包括终端设备的参考点的局部坐标。
举例来说，如果协议预先规定了终端设备的参考点的局部坐标默认的值。终端设备就不用在第一信息中上报终端设备的参考点的局部坐标，只需在第一信息中上报参考点对应的终端设备的天线标识。例如，第一信息包括：{天线标识1＝0，天线1的局部坐标＝(-0.5,0.5)}、{天线标识2＝1，天线2的局部坐标＝(0.5,-0.5)}、{天线标识3＝2，天线3的局部坐标＝(-0.5,-0.5)}、{天线标识4＝3，天线4的局部坐标＝(0.5,-0.5)}和{参考点的天线标识＝4}。由于协议预先规定了终端设备的参考点的局部坐标默认的值，定位管理设备根据协议的规定能够确定终端设备的参考点的局部坐标。例如，如果协议预先规定终端设备的参考点的局部坐标默认为局部坐标系中的原点，定位管理设备能够确定终端设备的参考点的局部坐标为(0,0)。相反，如果协议未预先规定终端设备的参考点的局部坐标默认的值，则第一信息 中除包括参考点对应的终端设备的天线标识之外，还可包括终端设备的参考点的局部坐标。例如，第一信息包括：{天线标识1＝0，天线1的局部坐标＝(-0.5,0.5)}、{天线标识2＝1，天线2的局部坐标＝(0.5,-0.5)}、{天线标识3＝2，天线3的局部坐标＝(-0.5,-0.5)}、{天线标识4＝3，天线4的局部坐标＝(0.5,-0.5)}和{参考点的天线标识＝4，参考点的局部坐标＝(0,0)}。
可选的，当终端设备的参考点不为终端设备的天线时，第一信息中还包括参考点的局部坐标。或者，第一信息中也可以不包括参考点的局部坐标。
举例来说，如果协议预先规定了终端设备的参考点的局部坐标默认的值。终端设备就不用在第一信息中上报终端设备的参考点的局部坐标。例如，第一信息包括：{天线标识1＝0，天线1的局部坐标＝(-0.5,0.5)}、{天线标识2＝1，天线2的局部坐标＝(0.5,-0.5)}、{天线标识3＝2，天线3的局部坐标＝(-0.5,-0.5)}、{天线标识4＝3，天线4的局部坐标＝(0.5,-0.5)}。由于协议预先规定了终端设备的参考点的局部坐标默认的值，定位管理设备根据协议的规定能够确定终端设备的参考点的局部坐标。例如，如果协议预先规定终端设备的参考点的局部坐标默认为局部坐标系中的原点，定位管理设备能够确定终端设备的参考点的局部坐标为(0,0)。相反，如果协议未预先规定终端设备的参考点的局部坐标默认的值，则第一信息中还可包括终端设备的参考点的局部坐标。例如，第一信息包括：{天线标识1＝0，天线1的局部坐标＝(-0.5,0.5)}、{天线标识2＝1，天线2的局部坐标＝(0.5,-0.5)}、{天线标识3＝2，天线3的局部坐标＝(-0.5,-0.5)}、{天线标识4＝3，天线4的局部坐标＝(0.5,-0.5)}和{参考点的局部坐标＝(0,0)}。
在一种可能的实现中，终端设备向定位管理设备发送第一信息的具体实施方式为：终端设备向定位管理设备发送终端设备的定位能力消息，终端设备的定位能力消息携带第一信息，该定位能力消息用于指示终端设备具有多天线确定定位信息的能力。相应地，定位管理设备接收终端设备发送的第一信息的具体实施方式为：定位管理设备接收终端设备发送的该定位能力消息。也就是说，终端设备将第一信息与终端设备的定位能力信息携带于同一消息中发送至定位管理设备。
其中，终端设备可以在执行步骤902之前，向定位管理设备发送终端设备的定位能力消息。多天线确定定位信息的能力是指终端设备是否具有通过多个天线标识对应的天线，测量接入网设备发送的下行参考信号的能力。通过实施该可能的实现方式，定位管理设备能够及时获取到终端设备的定位能力消息，这样定位管理设备后续才能确定是否能够采用多天线定位算法进行定位。并且通过将第一信息携带于定位能力消息中发送至定位管理设备，能够更早的使定位管理设备知道终端设备的天线标识以及其对应的天线局部坐标等信息。
在一种可能的实现中，如图10所示，定位管理设备接收终端设备发送的终端设备的定位能力消息之后，定位管理设备接收终端设备发送的测量信息之前，还可以执行步骤1002，即定位管理设备向终端设备发送上报请求，该上报请求用于请求上报包括终端设备的多个天线标识以及每个天线标识对应的下行参考信号的测量结果的测量信息。相应地，终端设备还可在向定位管理设备发送终端设备的定位能力消息之后，在通过多个天线标识对应的天线，测量接入网设备发送的下行参考信号之前，接收定位管理设备发送的该上报请求。其中，步骤1001、步骤1003～步骤1006的具体实现方式，在此不赘述。
也就是说，在该可能的实现中，定位管理设备可通过向终端设备发送上报请求，来请 求终端设备通过多个天线标识对应的天线，测量接入网设备发送的下行参考信号，并上报包括终端设备的多个天线标识以及每个天线标识对应的下行参考信号的测量结果的测量信息。通过实施该可能的实现方式，定位管理设备可根据定位需要灵活地从终端设备获取需要的测量信息。
可选的，定位管理设备可根据终端设备的业务定位精度需求来向终端设备发送上报请求。例如，如果终端设备的业务定位精度需求高于或等于预设值，则定位管理设备向终端设备发送上报请求，该上报请求用于请求终端设备上报包括终端设备的多个天线标识以及每个天线标识对应的下行参考信号的测量结果的测量信息。如果终端设备的业务定位精度需求低于预设值，则定位管理设备向终端设备发送上报请求，该上报请求用于请求终端设备上报单天线的测量信息(即在现有的方案中将终端设备的所有天线看作一个单天线进行信号测量，得到的测量结果)。基于该可选的方式，定位管理设备可根据终端设备的业务定位精度需求灵活地获取需要的测量信息。
在一种可能的实现中，如图11所示，终端设备通过多个天线标识对应的天线测量接入网设备发送的下行参考信号之前，还可执行步骤1101，即终端设备向定位管理设备发送终端设备的定位能力消息，该定位能力消息用于指示终端设备具有多天线确定定位信息的能力。相应地，定位管理设备还可在接收终端设备发送的测量信息之前，还可接收终端设备发送的该定位能力消息。其中，步骤1102～步骤1106的具体实现方式，在此不赘述。
也就是说，在该可能的实现中，第一信息不携带于定位能力消息中发送至定位管理设备。可选的，第一信息可以在定位能力消息之前发送至定位管理设备，或者第一信息可以在定位能力消息之后发送至定位管理设备。通过实施该可能的实现方式，定位管理设备能够及时获取到终端设备的定位能力消息，这样定位管理设备后续才能确定是否能够采用多天线定位算法进行定位。
在一种可能的实现中，如图12所示，定位管理设备接收终端设备发送的终端设备的定位能力消息之后，还可以执行步骤1202，即定位管理设备向终端设备发送上报请求，该上报请求用于请求上报第一信息和包括终端设备的多个天线标识以及每个天线标识对应的下行参考信号的测量结果的测量信息。相应地，终端设备还可在向定位管理设备发送终端设备的定位能力消息之后，在通过多个天线标识对应的天线，测量接入网设备发送的下行参考信号之前，接收定位管理设备发送的该上报请求。这样终端设备通过多个天线标识对应的天线，测量接入网设备发送的下行参考信号之后，就可以将测量信息和第一信息携带于同一消息中发送至定位管理设备。其中，步骤1201、步骤1203～步骤1206的具体实现方式，在此再不赘述。
基于该可能的实现方式，定位管理设备可根据定位需要灵活地从终端设备获取需要的测量信息。并且终端设备只需要在定位管理设备需要使用多天线定位算法时才上报第一信息，有利于节省通信资源。
可选的，定位管理设备可根据终端设备的业务定位精度需求来向终端设备发送上报请求。例如，如果终端设备的业务定位精度需求高于或等于预设值，则定位管理设备向终端设备发送上报请求，该上报请求用于请求终端设备上报第一信息和包括终端设备的多个天线标识以及每个天线标识对应的下行参考信号的测量结果的测量信息。如果终端设备的业务定位精度需求低于预设值，则定位管理设备向终端设备发送上报请求，该上报请求用于请求终端设备上报单天线的测量结果(即在现有的方案中将终端设备的所有天线看作一个 单天线进行信号测量，得到的测量结果)。基于该可选的方式，定位管理设备可根据终端设备的业务定位精度需求灵活地获取需要的测量信息。
综上所述，终端设备可以在定位能力消息中携带第一信息发送至定位管理设备。或者，第一信息可以在定位能力消息之前发送至定位管理设备，或者第一信息可以在定位能力消息之后发送至定位管理设备。或者，第一信息可以与测量信息携带于同一消息中发送至定位管理设备。
902、接入网设备向终端设备发送下行参考信号。
本申请实施例中，可以由一个或多个接入网设备向终端设备发送下行参考信号。下行参考信号可以为信道状态信息参考信号(channel state information-reference signal，CSI-RS)或者定位参考信号(positioning reference signal，PRS)等。
903、终端设备通过多个天线标识对应的天线，测量接入网设备发送的下行参考信号。
本申请实施例中，终端设备可通过多个天线标识对应的天线，测量一个或多个接入网设备发送的下行参考信号。这里的多个天线标识可以是第一信息中的部分天线标识也可以是第一信息中的全部天线标识。例如，第一信息中包括：{天线标识1＝0，天线1的局部坐标＝(-0.5,0.5)}、{天线标识2＝1，天线2的局部坐标＝(0.5,-0.5)}、{天线标识3＝2，天线3的局部坐标＝(-0.5,-0.5)}和{天线标识4＝3，天线4的局部坐标＝(0.5,-0.5)}。终端设备可通过天线1～天线4来测量接入网设备发送的下行参考信号。或者，终端设备可通过天线1～天线4中的2个或3个天线来测量接入网设备发送的下行参考信号。
在一种可能的实现中，终端设备通过多个天线标识对应的天线对下行参考信号进行测量，得到的测量结果可以为以下信息中的一种或多种：RSTD、RSRP、SS-RSRP、SS-RSRQ、SS-SINR或用户设备接收-发送时间差。关于RSTD、RSRP、SS-RSRP、SS-RSRQ、SS-SINR或用户设备接收-发送时间差的介绍可参见前述相关术语介绍对应的描述，在此不赘述。
在一种可能的实现中，接入网设备具有多个时，每个天线标识对应的天线均可以对所有接入网设备发送的下行参考信号进行测量，或者存在一个或多个天线标识对应的天线只对部分接入网设备发送的下行参考信号进行测量。需要保证步骤903中的多个天线标识中的每个天线标识对应的天线均会测量下行参考信号，至于采用哪个天线标识对应的天线测量哪个接入网设备发送的下行参考信号，本申请实施例不做限定。例如，接入网设备包括接入网设备1～接入网设备3。天线1和天线2均可对接入网设备1～接入网设备3发送的下行参考信号进行测量。或者，天线1对接入网设备1和接入网设备2发送的下行参考信号进行测量，天线2对接入网设备1和接入网设备3发送的下行参考信号进行测量。
904、终端设备向定位管理设备发送测量信息，该测量信息包括终端设备的多个天线标识以及每个天线标识对应的下行参考信号的测量结果。
本申请实施例中，终端设备得到多个天线标识对应的测量结果之后，向定位管理设备发送测量信息。该测量信息包括终端设备的多个天线标识以及每个天线标识对应的下行参考信号的测量结果。例如，终端设备上报的测量信息可以为：{测量结果1，天线标识1}、{测量结果2，天线标识2}、{测量结果3，天线标识3}和{测量结果4，天线标识4}。这样定位管理设备接收测量信息之后，就能基于该测量信息确定测量结果与天线标识的对应关系。
在一种可能的实现中，测量信息中包括的多个天线标识可以是步骤903中测量下行参考信号的全部或部分天线标识。终端设备得到多个天线标识对应的测量结果之后，可以只选择部分天线标识对应的测量结果进行上报。例如，终端设备得到天线标识1对应的测量 结果1～天线标识4对应的测量结果4之后，可以只上报{测量结果1，天线标识1}和{测量结果2，天线标识2}。
下面以测量结果为RSTD为例，对测量信息的信元结构进一步进行介绍：
假设接入网设备包括接入网设备1、接入网设备2和接入网设备3。接入网设备1为参考设备。终端设备通过天线标识1对应的天线1测量接入网设备1和接入网设备2发送的下行参考信号得到RSTD1。终端设备通过天线标识2对应的天线2测量接入网设备1和接入网设备2发送的下行参考信号得到RSTD2。终端设备通过天线标识3对应的天线3测量接入网设备1和接入网设备3发送的下行参考信号得到RSTD3。终端设备通过天线标识4对应的天线4测量接入网设备1和接入网设备3发送的下行参考信号得到RSTD4。在终端设备上报的测量信息中，接入网设备2对应的测量结果和该测量结果对应的天线标识的信元结构可以为以下信元结构：
Figure PCTCN2020087603-appb-000001
Figure PCTCN2020087603-appb-000002
在上述信元结构中，nr-RSTD-r16和nr-RSTD-ResultDiff-r16为RSTD的值。rx-ID为nr-RSTD-r16对应的天线标识。rx-ID-additional为nr-RSTD-ResultDiff-r16对应的天线标识。例如，nr-RSTD-r16可以为RSTD1，rx-ID为天线标识1。additionalDelay-r16可以为RSTD2，rx-ID-additional为天线标识2。在终端设备上报的测量信息中，接入网设备3对应的测量结果和该测量结果对应的天线标识的信元结构同理，在此不赘述。测量结果为RSRP、SS-RSRP、SS-RSRQ、SS-SINR或用户设备接收-发送时间差时，测量信息的信元结构类似，在此不赘述。

下面对定位管理设备基于第一信息和测量信息确定终端设备的绝对坐标的两种具体实施方式进行介绍：
方式一：终端设备的绝对坐标为终端设备的参考点的绝对坐标；参考点不为终端设备的天线；定位管理设备基于测量信息、第一信息中的天线标识以及其天线局部坐标，确定天线标识对应的绝对坐标；定位管理设备基于天线标识对应的绝对坐标、天线标识对应的天线局部坐标和参考点的局部坐标确定参考点的绝对坐标。
举例来说，第一信息包括：{天线标识1＝0，天线1的局部坐标＝(-0.5,0.5)}、{天线标识2＝1，天线2的局部坐标＝(0.5,-0.5)}、{天线标识3＝2，天线3的局部坐标＝(-0.5,-0.5)}、{天线标识4＝3，天线4的局部坐标＝(0.5,-0.5)}和{参考点的局部坐标＝(0,0)}。测量信息包括：{测量结果1，天线标识1}、{测量结果2，天线标识2}、{测量结果3，天线标识3}和{测量结果4，天线标识4}。定位管理设备接收第一信息和测量信息之后，先基于测量结果1确定天线1的初始绝对坐标，并基于测量结果2确定天线2的初始绝对坐标，并基于测量结果3确定天线3的初始绝对坐标，并基于测量结果4确定天线4的初始绝对坐标。然后定位管理设备基于第一信息中的天线1～天线4的局部坐标确定天线1～天线4之间的相对位置关系。定位管理设备基于天线1～天线4之间的相对位置关系来对天线1的初始绝对坐标～天线4的初始绝对坐标进行校准，并将校准后的绝对坐标确定为最终天线1～天线4的绝对坐标。 定位管理设备确定天线1～天线4的绝对坐标之后，再结合天线1～天线4的天线局部坐标和参考点的局部坐标就能确定参考点的绝对坐标。
方式二：终端设备的绝对坐标为终端设备的参考点的绝对坐标，参考点为终端设备的天线，测量信息中包括参考点对应的测量结果；定位管理设备基于测量信息、参考点的局部坐标和第一信息中的天线标识以及其天线局部坐标，确定天线标识对应的绝对坐标和参考点的绝对坐标。
举例来说，第一信息包括：{天线标识1＝0，天线1的局部坐标＝(-0.5,0.5)}、{天线标识2＝1，天线2的局部坐标＝(0.5,-0.5)}、{天线标识3＝2，天线3的局部坐标＝(-0.5,-0.5)}、{天线标识4＝3，天线4的局部坐标＝(0.5,-0.5)}和{参考点的天线标识＝4，参考点的局部坐标＝(0,0)}。测量信息包括：{测量结果1，天线标识1}、{测量结果2，天线标识2}、{测量结果3，天线标识3}、{测量结果4，天线标识4}和{测量结果5，参考点的天线标识}。定位管理设备接收第一信息和测量信息之后，先基于测量结果1确定天线1的初始绝对坐标，并基于测量结果2确定天线2的初始绝对坐标，并基于测量结果3确定天线3的初始绝对坐标，并基于测量结果4确定天线4的初始绝对坐标，并基于测量结果5确定参考点的初始绝对坐标。然后定位管理设备基于第一信息中的天线1～天线4和参考点的局部坐标确定天线1～天线4和参考点之间的相对位置关系。定位管理设备基于天线1～天线4和参考点之间的相对位置关系来对天线1的初始绝对坐标～天线4的初始绝对坐标和参考点的初始绝对坐标进行校准，并将校准后的绝对坐标确定为最终天线1～天线4的绝对坐标和参考点的绝对坐标。
基于上述方式一或方式二，能够准确地确定出终端设备的绝对坐标。
在一种可能的实现中，定位管理设备基于天线信息和测量信息确定终端设备的朝向或姿态信息，和/或旋转角，和/或终端设备的上下倾角的具体实施方式为：定位管理设备基于测量信息、多个天线标识以及每个天线标识对应的天线局部坐标，确定每个天线标识对应的绝对位置；定位管理设备基于每个天线标识对应的绝对位置和每个天线标识对应的天线局部坐标之间的转换关系，确定终端设备的朝向或姿态信息，和/或旋转角，和/或终端设备的上下倾角。其中，定位管理设备基于测量信息、多个天线标识以及每个天线标识对应的天线局部坐标，确定每个天线标识对应的绝对位置的具体实现方式可参见前述所述，在此不赘述。基于该可能的实现，能够准确地确定终端设备的朝向或姿态信息，和/或旋转角，和/或终端设备的上下倾角。

关于步骤1301中天线标识和天线局部坐标的相关描述，可参见上述901的描述，在此不赘述。其中，步骤1301可在步骤1302之前执行。
在一种可能的实现中，第一信息中还包括终端设备的参考点的局部坐标和/或参考点对应的终端设备的天线标识。其中，终端设备的参考点的位置用于表征终端设备的位置，即终端设备的绝对坐标为终端设备的参考点的绝对坐标。通过实施该可能的实现方式，定位管理设备在获取终端设备的参考点的局部坐标和/或参考点对应的终端设备的天线标识之后，就可以基于终端设备的参考点的局部坐标和/或参考点对应的终端设备的天线标识确定终端设备的参考点的绝对坐标，进而确定终端设备的绝对坐标。关于参考点的其他相关描述可参见上述图9所对应的实施例，在此不赘述。
在一种可能的实现中，终端设备向定位管理设备发送第一信息的具体实施方式为：终端设备向定位管理设备发送终端设备的定位能力消息，终端设备的定位能力消息携带第一信息，该定位能力消息用于指示终端设备具有多天线确定定位信息的能力。相应地，定位管理设备接收终端设备发送的第一信息的具体实施方式为：定位管理设备接收终端设备发送的该定位能力消息。也就是说，终端设备将第一信息与终端设备的定位能力信息携带于同一消息中发送至定位管理设备。
多天线确定定位信息的能力是指终端设备是否具有通过多个天线标识对应的天线，测量接入网设备发送的下行参考信号的能力。通过实施该可能的实现方式，定位管理设备能够及时获取到终端设备的定位能力消息，这样定位管理设备后续才能确定是否能够采用多天线定位算法进行定位。并且通过将第一信息携带于定位能力消息中发送至定位管理设备，能够更早的使定位管理设备知道终端设备的天线标识以及其对应的天线局部坐标等信息。
1302、终端设备通过多个天线标识对应的天线向接入网设备发送上行参考信号。
本申请实施例中，终端设备发送第一信息之后，可通过多个天线标识对应的天线向一个或多个接入网设备发送上行参考信号。这里的多个天线标识可以是第一信息中的部分天线标识也可以是第一信息中的全部天线标识。上行参考信号可以为(sounding reference signal，SRS)或者为其他上行参考信号。
1303、接入网设备测量终端设备通过多个天线标识对应的天线发送的上行参考信号。

在一种可能的实现中，接入网设备具有多个时，每个接入网设备均可对上述多个天线标识中的所有天线标识对应的天线所发送的上行参考信号进行测量，或者存在一个或多个天接入网设备只对上述多个天线标识中的部分天线标识对应的天线所发送的上行参考信号进行测量。但是需要保证上述多个天线标识中的每个天线标识对应的天线所发送的上行参考信号需要被测量。至于哪个接入网设备测量哪个天线标识对应的天线所发送的上行参考信号，本申请实施例不做限定。例如，接入网设备包括接入网设备1和接入网设备2。接入网设备1可以对天线1和天线2发送的下行参考信号进行测量，接入网设备2可以对天线1和天线2发送的下行参考信号进行测量。或者，接入网设备1可以对天线1发送的下行参考信号进行测量，接入网设备2可以对天线2发送的下行参考信号进行测量。

在一种可能的实现中，一个或多个接入网设备得到多个上行参考信号资源和/或资源集的索引对应的测量结果之后，可以只选择全部或部分多个上行参考信号资源和/或资源集的索引对应的测量结果进行上报。例如，一个或多个接入网设备得到测量结果1～测量结果4之后，测量信息中可以只包括：{测量结果1，上行参考信号资源1和/或资源集1的索引}和{测量结果2，上行参考信号资源2和/或资源集2的索引}。

可见，通过实施图13所描述的下行的定位信息的确定方法，定位管理设备可以结合第一信息和对多个天线标识发送的上行参考信号的测量结果，确定终端设备的定位信息，有利于提升确定的终端设备的定位信息的精度。并且图13所描述的方法，也可以通过一个接入网设备接收上行参考信号来确定终端设备的定位信息，有利于对终端设备降低定位或定朝向或定姿态的环境部署条件。
请参见图14，图14是本申请实施例提供的另一种上行的定位信息的确定方法的流程示意图。如图14所示，该上行的定位信息的确定方法包括如下步骤1401～步骤1408。其中：
1401、终端设备向定位管理设备发送第一信息，该第一信息包括终端设备的多个天线标识以及该多个天线标识中每个天线标识对应的天线局部坐标。相应地，定位管理设备可以接收终端设备发送的该第一信息。
其中，步骤1401的具体实现方式可参见上述步骤1301，在此不赘述。
1402、定位管理设备接收终端设备的服务小区发送的多个第一配置信息。
其中，该多个第一配置信息用于配置多个上行参考信号资源和/或资源集，每个第一配置信息包括上行参考信号资源和/或资源集的索引以及上行参考信号资源和/或资源集对应的终端设备的天线标识。上行参考信号资源和/或资源集对应的终端设备的天线标识是指用于在该上行参考信号资源和/或资源集发送上行参考信号的天线的标识。也就是说，第一配置信息中隐含了上行参考信号资源和/或资源集的索引与终端设备的天线标识之间的对应关系。
举例来说，上述多个第一配置信息为第一配置信息1和第一配置信息2。其中，第一配置信息1用于配置上行参考信号资源1。第一配置信息1包括上行参考信号资源1的索引以及上行参考信号资源1对应的终端设备的天线标识1。第一配置信息2用于配置上行参考信号资源2。第一配置信息2包括上行参考信号资源2的索引以及上行参考信号资源2对应的终端设备的天线标识2。例如，以上行参考信号为SRS参考信号为例，第一配置信息1的信元结构可以为：
Figure PCTCN2020087603-appb-000003

其中，srs-ResourceId tx-ID为上行参考信号资源1的索引，tx-ID为终端设备的天线标识1。第二配置信息2的信元结构类似，在此不赘述。
其中，步骤1402可在步骤1401之前执行，或者在步骤1401之后执行，本申请实施例不做限定。
1403、定位管理设备向接入网设备发送多个上行参考信号资源和/或资源集的第二配置信息。相应地，接入网设备可接收定位管理设备发送的多个上行参考信号资源和/或资源集的第二配置信息。
其中，每个第二配置信息包括第一配置信息中的上行参考信号资源和/或资源集的索引。举例来说，上述多个第一配置信息为第一配置信息1和第一配置信息2。第一配置信息1包括上行参考信号资源1的索引以及上行参考信号资源1对应的终端设备的天线标识1。第一配置信息2包括上行参考信号资源2的索引以及上行参考信号资源2对应的终端设备的天线标识2。那么定位管理设备向接入网设备发送第二配置信息1和第二配置信息2。第二配置信息1包括上行参考信号资源1的索引。第二配置信息2包括上行参考信号资源2的索引。
可选的，第二配置信息也可以和第一配置信息相同。
1404、定位管理设备向终端设备发送多个第一配置信息。相应地，终端设备可接收定位设备发送的多个第一配置信息。
其中，步骤1404的可在步骤1401～1403之前执行，或在步骤1401～1403之后执行，本申请实施例不做限定。
在一种可能的实现中，步骤1404也可以不执行，可以由终端设备的服务小区向终端设备发送多个第一配置信息。相应地，终端设备可接收终端设备的服务小区发送的多个第一配置信息。
在一种可能的实现中，步骤1402也可以不执行。定位管理设备可以自己生成多个第一配置信息。定位管理设备生成多个第一配置信息之后，可以向接入网设备发送多个上行参考信号资源和/或资源集的第二配置信息，以及向终端设备发送多个第一配置信息。在该可能的实现中，定位管理设备需要提前从终端设备的服务小区获取用于配置多个上行参考信号资源和/或资源集的多个配置信息，定位管理设备根据该多个配置信息和第一信息中的天线标识来生成多个第一配置信息。例如，定位管理设备从终端设备的服务小区获取的多个配置信息包括配置信息1和配置信息2。配置信息1用于配置上行参考信号资源1和/或资源集1，配置信息1包括上行参考信号资源1和/或资源集1的索引。配置信息2用于配置上行参考信号资源2和/或资源集2，配置信息2包括上行参考信号资源2和/或资源集2的索引。第一信息中包括：{天线标识1，天线1的局部坐标＝(-0.5,0.5)}、{天线标识2，天线2的局部坐标＝(0.5,-0.5)}。那么定位管理设备可以生成第一配置信息1和第一配置信息2。第一配置信息1中包括上行参考信号资源1和/或资源集1的索引和天线标识1。第一配置信息2中包括上行参考信号资源2和/或资源集2的索引和天线标识2。
1405、终端设备通过多个天线标识对应的天线向接入网设备发送上行参考信号。
本申请实施例中，终端设备接收多个第一配置信息之后，可以基于第一配置信息来发送上行参考信号；或者，终端设备接收多个第一配置信息之后，也可以不基于第一配置信息来发送上行参考信号，终端设备可根据自身的需求来确定在上行参考信号资源发送参考信号所采用的天线。也就是说，第一配置信息可用于强制要求终端设备基于第一配置信息来发送上行参考信号。或者，第一配置信息只用于向终端设备推荐在上行参考信号资源发送参考信号所采用的天线，终端设备具体在上行参考信号资源发送参考信号采用哪个天线由终端设备根据自身需求自己确定。因此，通过实施上述步骤1402～步骤1404，能够向终端设备要求或推荐在上行参考信号资源或资源集发送上行参考信号所采用的天线。
在一种可能的实现中，终端设备通过多个天线标识对应的天线向接入网设备发送上行参考信号的具体实施方式为：终端设备基于多个第一配置信息，通过多个天线标识对应的天线在相应的上行参考信号资源和/或资源集上向接入网设备发送上行参考信号。相应地，定位管理设备基于第一信息和测量信息确定终端设备的定位信息的具体实施方式为：定位管理设备根据每个测量结果对应的上行参考信号资源和/或资源集的索引和多个第一配置信息，确定每个测量结果对应的终端设备的天线标识；定位管理设备根据第一信息、每个测量结果、每个测量结果对应的终端设备的天线标识确定终端设备的定位信息。
在该可能的实现方式中，第一配置信息用于强制要求终端设备基于第一配置信息来发送上行参考信号。因此，终端设备会基于多个第一配置信息，通过多个天线标识对应的天线在相应的上行参考信号资源和/或资源集上向接入网设备发送上行参考信号。基于该可能 的实现方式，有利于准确地确定每个测量结果对应的终端设备的天线标识。
举例来说，第一配置信息1中包括上行参考信号资源1和/或资源集1的索引和天线标识1。第一配置信息2中包括上行参考信号资源2和/或资源集2的索引和天线标识2。终端设备采用天线标识1对应的天线1在上行参考信号资源1和/或资源集1上发送上行参考信号。终端设备采用天线标识2对应的天线2在上行参考信号资源2和/或资源集2上发送上行参考信号。接入网设备在上行参考信号资源1和/或资源集1上进行上行参考信号测量，得到测量结果1。接入网设备在上行参考信号资源2和/或资源集2上进行上行参考信号测量，得到测量结果2。接入网设备向定位管理设备发送的测量信息包括：{上行参考信号资源1和/或资源集1的索引，测量结果1}和{上行参考信号资源2和/或资源集2的索引，测量结果2}。定位管理设备接收该测量信息之后，基于第一配置信息1和{上行参考信号资源1和/或资源集1的索引，测量结果1}，可以确定测量结果1对应天线标识1，即测量结果1是对天线标识1对应的天线1所发送的参考信号进行测量得到的。同理，定位管理设备基于第一配置信息2和{上行参考信号资源2和/或资源集2的索引，测量结果2}，可以确定测量结果2对应天线标识2，即测量结果2是对天线标识2对应的天线2所发送的参考信号进行测量得到的。定位管理设备根据第一信息、测量结果1和测量结果1对应的天线标识1、测量结果2和测量结果2对应的天线标识2确定终端设备的定位信息。
在一种可能的实现中，终端设备还可向定位管理设备上报第二信息，该第二信息包括终端设备发送的上行参考信号资源或资源集的索引以及与终端设备发送的上行参考信号资源和/或资源集相对应的终端设备的天线标识。相应地，定位管理设备还可接收终端设备上报的第二信息，该第二信息包括终端设备发送的上行参考信号资源或资源集的索引以及与终端设备发送的上行参考信号资源和/或资源集相对应的终端设备的天线标识；定位管理设备基于第一信息和测量信息确定终端设备的定位信息的具体实施方式为：定位管理设备根据每个测量结果对应的上行参考信号资源和/或资源集的索引和第二信息，确定每个测量结果对应的终端设备的天线标识；定位管理设备根据第一信息、每个测量结果和每个测量结果对应的终端设备的天线标识确定终端设备的定位信息。
在该可能的实施方式中，第二信息指示了终端设备在上行参考信号资源发送参考信号实际采用的天线。第一配置信息只用于向终端设备推荐在上行参考信号资源发送参考信号所采用的天线，终端设备具体在上行参考信号资源发送参考信号采用哪个天线由终端设备根据自身需求自己确定。因此，终端设备通过多个天线标识对应的天线发送上行参考信号之后，需要发送第二信息。以便定位管理设备能够确定终端设备在上行参考信号资源发送参考信号实际采用的天线，进而后续可以基于该第二信息准确地确定接入网设备上报的每个测量结果所对应的终端设备的天线标识。定位管理设备根据每个测量结果对应的上行参考信号资源和/或资源集的索引和第二信息，确定每个测量结果对应的终端设备的天线标识的具体实现原理与上述定位管理设备根据每个测量结果对应的上行参考信号资源和/或资源集的索引和第一配置信息，确定每个测量结果对应的终端设备的天线标识的具体实现原理相同，在此不赘述。值得一提的是，当步骤1402～步骤1404不执行时，也可以终端设备也可向定位管理设备上报第二信息。
在一种可能的实现中，终端设备的绝对坐标为终端设备的参考点的绝对坐标，参考点不为终端设备的天线，定位管理设备根据第一信息、每个测量结果和每个测量结果对应的终端设备的天线标识确定终端设备的绝对坐标的具体实施方式为：定位管理设备基于每个 测量结果、每个测量结果对应的终端设备的天线标识、第一信息中的天线标识以及其天线局部坐标，确定天线标识对应的绝对位置；定位管理设备基于天线标识对应的绝对位置、天线标识对应的天线局部坐标和参考点的局部坐标确定参考点的绝对坐标。该可能的实现方式的具体实现可参见上述图9所对应的实施例中的描述，在此不赘述。
