Description

定位方法及装置 技术领域
本申请涉及通信领域，尤其涉及一种定位方法及装置。
背景技术
无线定位技术已被确定为第三代合作伙伴计划(3rd generation partnership project，3GPP)第五代(5th generation，5G)移动通信技术中的重要研究项目，应用场景包括自动驾驶、智能驾驶、车联网、工业物联网(industrial internet of things，IIoT)等。其中，工业物联网通常为较为封闭的无线通信环境，无线信号的传播路径较为复杂，如多次反射、折射、散射等，也就是存在严重的多径(multi-path)传播现象。
然而，目前常用的无线定位算法，如观察到达时间差(observed time difference of arrival，OTDOA)算法，上行到达角(uplink angle of arrival，UAOA)算法等，是根据无线信号的到达时间和/或到达角度进行定位的，而在IIoT应用场景下，严重的多径现象会导致检测到的到达时间和到达角度不准确，从而导致定位精度差，不能满足诸如IIoT等多径多发场景下的定位精度需求。

下面将结合图4-图6对本申请实施例提供的定位方法进行具体阐述。
示例性地，图4为本申请实施例提供的定位方法的流程示意图一。该定位方法可以适用于图1中所示出的定位管理网元与定位测量网元之间的通信，或者适用于图2中所示出的LMF网元与SgNB和/或NgNB之间的通信，或者适用于图2中所示出的LMF网元与终端设备之间的通信。
如图4所示，该定位方法包括如下步骤：
S401，定位管理网元向定位测量网元发送定位测量请求。相应地，定位测量网元从定位管理网元接收定位测量请求。
其中，定位测量请求用于请求定位测量网元反馈终端设备的信道状态信息。
在一种可能的设计方案中，终端设备的信道状态信息可以在时域或频域上进行区分，即终端设备的信道状态信息可以包括时域信道状态信息或频域信道状态信息。
示例性地，表1为本申请实施例提供的定位测量请求的示例一。如表1所示，定位测量请求可以包括如下一项或多项信息：参考信号配置(RS configuration)信息、域(domain)配置信息、天线端口对(antenna port pair)配置信息、时域(time domain)信息、频域(frequency domain)信息。
其中，参考信号配置信息用于指示测量信道状态时使用的参考信号的配置信息，如参考信号的类型(type)、索引(index)、空口资源(radio resource)配置等。其中，参考信号的类型可以为探测用参考信号(sounding reference signal，SRS)、定位参考信号(positioning reference signal，PRS)、信道状态信息参考信号(channel state information reference signal，CSI-RS)中的一种，索引为配置的SRS、PRS、CSI-RS的编号，用于指示配置的参考信号具体使用哪一个参考信号序列。定位测量网元可以根据参考信号配置信息对配置的参考信号进行检测，如使用配置的参考信号的本地共轭序列与参考信号的接收信号做相关操作或匹配滤波操作，从而获取终端设备的信道状态信息。
其中，域配置信息用于指示上报时域信道状态信息(time domain channel state  information，TD-CSI)或频域信道状态信息(frequency domain channel state information，FD-CSI)。可选地，可以由定位管理网元确定并指示定位测量网元需要上报的状态信息为时域信道状态信息(对应表1中的取值为1的选项)或频域信道状态信息(对应表1中的取值为2的选项)。
或者，可选地，定位管理网元也可以指示定位测量网元自行选择需要上报的状态信息为时域信道状态信息或频域信道状态信息(对应表1中的取值为0的选项)。在此情况下，鉴于时域信道状态信息和频域信道状态信息在确定终端设备的位置的过程中所起的作用是等效的，定位测量网元可以根据时域信道状态信息的数据量与频域信道状态信息的数据量的大小，自行选择上报哪一种信道状态信息，如上报数据量较小的信道状态信息，以节省资源和传输时间，从而提高定位效率。
其中，天线端口对配置信息用于指示需要上报信道状态的天线端口对，如需要上报的天线端口对的索引或数量。以2发2收的多数多输出(multiple-input multiple-output，MIMO)为例，发射天线为T0、T1，接收天线为R0、R1，则天线端口对的索引取值为0至3的天线端口对依次为：T0R0、T0R1、T1R0、T1R1，天线端口对总数为4。若天线端口对的索引取值为0和1，则定位测量网元测量并上报天线端口对T0R0和T0R1的信道状态信息。
上述天线端口对的数量用于指示定位测量网元按照预设规则自行选择需要上报信道状态信息的天线端口对。可选地，预设规则可以是按照天线端口对的索引从小到大顺序选择需要上报信道状态信息的天线端口对。例如，若天线端口对的数量为2，则指示定位测量网元按照预设规则自行选择需要上报的天线端口对。
或者，可选地，预设规则也可以是：测量所有天线端口对的信道状态信息，并按照测量得到的信道状态信息对应的信道状态从高到低顺序，选择需要上报信道状态信息的天线端口对。例如，若上述4个所有天线端口对的信道状态信息按照从高到低顺序依次为：T0R0、T1R1、T0R1、T1R0，且需要上报信道状态信息的天线端口对的数量为2，则定位测量网元选择上报天线端口对T0R0、T1R1的信道状态信息。
应理解，上述需要上报信道状态的天线端口对的数量可以为天线端口对数，如1个、2个等，也可以为需要上报的天线端口对数占比，如25％、50％等，本申请实施例对此不做具体限定。
其中，时域信息用于指示测量信道状态时使用的时域参数，频域信息用于指示测量信道状态时使用的频域参数。其中，时域信道状态信息、频域信道状态信息在对终端设备进行定位的过程中所起的作用是等效的。如此，定位管理网元可以择一的方式指示定位测量网元测量和上报时域信道状态信息或频域信道状态信息，可以减少定位测量网元的测量工作量和上报数据量，从而提高定位效率。
可选地，如表1所示，时域信息可以包括如下一项或多项信息：需要上报的总路径数量(path number)、路径功率阈值(path power threshold)、路径幅度阈值(path ampitude threshold)。如此，可以进一步减少定位测量网元测量和上报的时域信道状态信息的工作量，从而进一步提高定位效率。
可选地，如表1所示，频域信息可以包括如下一项或多项信息：需要上报的频域范围(frequency range)、子载波间隔(sub-carrier interval)、无线承载间隔(radio bearer  interval)。如此，可以进一步减少定位测量网元测量并上报的频域信道状态信息的工作量，从而进一步提高定位效率。
进一步地，上述需要上报的频域范围可以采用如下方式之一表示：起始频率+结束频率、起始频率+频率偏移量、起始子载波索引+结束子载波索引、起始子载波索引+子载波偏移量(以子载波为单位)、起始RB索引+结束RB索引、起始RB索引+RB偏移量(以RB为单位)等，本申请实施例对此不做具体限定。
需要说明的是，定位测量请求中的各项配置参数均为可选。当某一项或多项参数未配置时，视为指示定位测量网元测量并上报的信道状态信息为该一项或多项参数对应的所有信道状态信息。例如，若天线端口对未配置，则视为指示定位测量网元测量并上报所有天线端口对的信道状态信息。又例如，若需要上报的总路径数量未配置，则视为指示定位测量网元测量并上报所有检测到的多径的信道状态信息。再例如，若需要上报的频率范围配置，则视为指示定位测量网元测量并上报终端设备的系统带宽内所有子载波、或所有RB的信道状态信息。

应理解，定位管理网元可以从不同的定位测量网元接收终端设备的UL-CSI或DL-CSI，下面具体说明。
可选地，定位测量网元可以包括终端设备的服务接入网(serving radio access network)网元，如服务基站，和/或，服务接入网网元的相邻接入网(neighbor radio access network)网元，如服务基站的相邻基站。相应地，上述终端设备的信道状态信息可以包括终端设备的UL-CSI，定位测量请求用于请求终端设备的服务接入网网元，和/或，服务接入网网元的相邻接入网网元反馈终端设备的UL-CSI。如此，定位管理网元可以只指示终端设备的服务接入网网元，或服务接入网网元的相邻接入网网元测量和上报终端设备的UL-CSI，可以减少定位测量网元的数量和测量工作量，从而提高定位效率。
可选地，上述参考信号配置信息可以包括上行参考信号，如SRS的配置信息，上行参考信号的配置信息可以包括如下一项或多项信息：SRS的时域配置、频域配置、端口号、波束(beam)信息。如此，终端设备的服务接入网网元，和/或，服务接入网网元的相邻接入网网元可以只测量配置的SRS所对应的终端设备的UL-CSI，可以进一步减少定位测量网元的测量工作量，从而进一步提高定位效率。
需要说明的是，当定位测量网元为接入网网元时，接入网网元还需要向终端设备发送SRS的配置信息，如上述SRS的索引、时域配置、频域配置、端口号、波束(beam)信息，以指示终端设备按照SRS的配置信息发送SRS信号，如在指定的天线端口的指定波束上的指定时频资源上发送承载指定SRS序列的SRS信号。相应地，定位测量网元可以检测终端设备发送的SRS信号，从而获取UL-CSI。
或者，可选地，定位测量网元也可以为终端设备，终端设备的信道状态信息可以包括终端设备的下行信道状态信息DL-CSI，定位测量请求用于请求终端设备的DL-CSI。如此，定位管理网元可以只指示终端设备测量该终端设备的DL-CSI，可以减少定位测量网元的数量和测量工作量，从而提高定位效率。
可选地，上述参考信号配置信息可以包括下行参考信号，如PRS或CSI-RS的配置信息，下行参考信号的配置信息可以包括如下一项或多项信息：PRS的时域配置、频域配置、端口号、波束(beam)信息，或者CSI-RS的时域配置、频域配置、端口号、波束(beam)信息。如此，终端设备可以只测量配置的PRS或CSI-RS所对应的终端设备的DL-CSI，以进一步减少终端设备的测量工作量，从而进一步提高定位效率。
需要说明的是，当定位测量网元为终端设备时，服务接入网网元还可以向终端设备转发上述定位测量请求，终端设备可以根据定位测量请求中的参考信号配置信息，如上述PRS或CSI-RS的配置信息，生成PRS或CSI-RS的本地共轭序列，并使用该本地共轭序列检测接收到的参考信号，从而获得终端设备的DL-CSI，然后按照定位测量请求，通过服务接入网网元向定位测量网元上报DL-CSI。相应地，接入网网元，如服务接入网网元和/或相邻接入网网元，在从定位管理网元接收定位测量请求后，可以根据PRS或CSI-RS的配置信息，如上述PRS或CSI-RS的索引、时域配置、频域配置、端口号、波束(beam)信息，向终端设备发送PRS信号或CSI-RS信号，如在指定的天线端口的指定波束上的指定时频资源上发送承载指定PRS序列或CSI-RS序列 的SRS信号。如此，终端设备可以只测量服务接入网网元或相邻接入网网元发送的PRS或CSI-RS所对应的终端设备的DL-CSI，可以进一步减少定位测量网元的测量工作量，从而进一步提高定位效率。
可选地，定位测量请求可以是定位管理网元根据终端设备的DL-CSI测量能力信息确定的。如此，定位管理网元可以根据终端设备的DL-CSI测量能力信息，确定该终端设备的测量任务的内容和该终端设备上报的DL-CSI的内容，以避免向该终端设备下发超出其DL-CSI测量能力的测量任务所导致的无效信令交互，从而提高定位效率。
进一步地，在上述定位管理网元向定位测量网元发送定位测量请求之前，图4所示的定位方法还可以包括：
终端设备向定位管理网元发送终端设备的DL-CSI测量能力信息。相应地，定位管理网元接收终端设备的DL-CSI测量能力信息。其中，终端设备的DL-CSI测量能力信息用于定位管理网元确定定位测量请求，如确定定位测量请求携带的各项配置信息。
应理解，终端设备可以主动向定位管理网元发送终端设备的DL-CSI测量能力信息，如该终端设备可以在网络注册时通过服务接入网网元向定位管理网元上报其DL-CSI测量能力信息，也可以在其从定位管理网元接收到DL-CSI测量能力查询请求后，向定位管理网元发送其DL-CSI测量能力信息。
还应理解，除终端设备之外，定位管理网元也可以从服务接入网网元、AMF网元、OAM网元等其他网元获取该终端设备的DL-CSI测量能力信息。本申请实施例对于定位管理网元获取终端设备的DL-CSI测量能力信息的实现方式，不做具体限定。
可选地，定位测量请求还可以包括如下一项或多项信息：终端设备的服务接入网网元的配置信息、服务接入网网元的相邻接入网网元的配置信息，如上述各接入网网元的邻区配置信息、基站标识、小区标识、位置信息等。进一步地，可以结合该终端设备对多个小区发射的下行参考信号的测量结果定位该终端设备，以进一步提高定位精度。
需要说明的是，上述从时域或频域区分信道状态信息的方案和从信号传输方向上区分信道状态信息的方案也可以结合使用，以进一步减少定位测量网元的测量工作量，从而提高定位效率。例如，可以指示终端设备只上报时域上的DL-CSI。又例如，可以指示接入网网元只上报频域上的UL-CSI。本申请实施例对于上述两种方案的结合方式，不做具体限定。
S402，定位测量网元向定位管理网元发送定位测量响应。相应地，定位管理网元从定位测量网元接收定位测量响应。
其中，定位测量响应包括终端设备的信道状态信息。
在一种可能的设计方案中，终端设备的信道状态信息可以在时域或频域上进行区分，即终端设备的信道状态信息可以包括时域信道状态信息或频域信道状态信息。

其中，域指示信息用于指示上报的终端设备的信道状态信息为时域信道状态信息或频域信道状态信息。结合表1，域指示信息的取值可以是由定位管理网元确定，并 通过上述定位测量请求的域配置信息字段(field)(取值为0或1)下发给定位测量网元的，也可以是定位测量网元根据定位测量请求中的取值为2的域配置信息字段的指示自行确定的，如定位测量网元可以从终端设备的时域信道状态信息和频域信道状态信息中选择上报数据量较少的信道状态信息。其中，时域信道状态信息、频域信道状态信息在对终端设备进行定位的过程中所起的作用是等效的。如此，定位管理网元可以指示定位测量网元以择一的方式上报时域信道状态信息或频域信道状态信息，可以减少定位测量网元需要上报的信道状态信息的数据量，从而提高定位效率。
可选地，如表2所示，时域信道状态信息可以包括如下一项或多项信息：上报的总路径数量、上报的路径中每条路径的时延、上报的路径中每条路径的幅度、上报的路径中每条路径的功率、上报的路径中每条路径的相位。如此，可以进一步减少定位测量网元需要上报的时域信道状态信息的数据量，从而进一步提高定位效率。

需要说明的是，表2中所示出的各项内容均为可选。例如，结合表1，若定位测量请求中的域配置信息字段的取值为0或1，即定位管理网元已明确指示定位测量网元上报时域信道状态信息或频域信道状态信息，则定位测量网元可以不上报表2中的域指示信息字段。再例如，结合表1，若定位测量请求中的天线端口对配置信息字段的取值为需要上报的一个天线端口对的索引，即定位管理网元已明确指示定位测量网元上报的信道状态信息为哪些天线端口对的，或者定位测量请求中的天线端口对配置信息字段的取值为需要上报的天线端口对的数量，且定位管理网元和定位测量网元均可以根据需要上报的天线端口对的数量和预设规则，唯一地确定上报的信道状态信息所对应的天线端口对，则定位测量网元可以不上报表2中的天线端口对指示信息字段。再例如，鉴于时域信道状态信息和频域信道状态信息在确定终端设备的位置的过程中所起的作用是等效的，定位测量网元可以只上报其中一种信道状态信息。如此，可以进一步减少定位测量网元上报的数据量，以节省上报资源开销。
进一步地，除表2中所示出的内容之外，定位测量网元还可以向定位管理网元上报下述表3中所示出的接入网网元信息和/或参考信号测量结果。下面具体说明。
