Description

一种定位方法、装置、终端及设备
相关申请的交叉引用
本公开要求在2020年10月27日提交中国专利局、申请号为202011168407.7、名称为“一种定位方法、装置、终端及设备”的中国专利申请的优先权，其全部内容通过引用结合在本公开中。
技术领域
本公开涉及移动通信技术领域，尤其涉及一种定位方法、装置、终端及设备。
背景技术
在新空口(New Radio，NR)系统中，终端通过测量多个发送接收节点(Transmission and Reception Point，TRP)发送的定位参考信号(Positioning Reference Signal，PRS)，实现下行定位。其中，每个终端可以测量最多4个频率层发送的PRS信号。每个频率层对应一个频率带宽，其中，NR系统中规定，每个频率层最多包含276个物理资源块(Physical Resource Block，PRB)，其频域位置由定位服务器配置给终端。如图1所示。在每个频率层下，可以配置多个TRP发送定位参考信号。每个TRP可以配置发送多个定位参考信号的定位参考信号资源集。每个定位参考信号资源集中可以包括多个定位参考信号资源。一个定位参考信号资源集中的多个定位参考信号资源可以采用不同的发送波束，以实现对终端的覆盖。
终端测量一个频率层的不同TRP发送的定位参考信号后，获得不同TRP的定位测量值。将定位测量值上报给定位服务器，由定位服务器解算出终端的位置信息。
因此，定位精度与定位参考信号的带宽相关。带宽越大，其时间分辨率越高，定位精度越高。目前的定位方法，定位参考信号的带宽受限于一个频率层的带宽。这种情况对于定位精度要求较高的场景(例如：工业物联网场景)，难以达到定位精度需求。

图1示出了本公开实施例提供的一种定位方法的流程示意图。该方法应用于终端，具体可以包括如下步骤：
步骤101，接收定位配置信息，所述定位配置信息可以包括但不限于以下至少一项：定位参考信号配置信息和第一频率层误差参数。
具体的，在上述步骤101中，所述终端接收的定位配置信息可以是基站发送的，也可以是定位服务器发送的，在此不做具体限定。其中，基站确定定位配置信息，并将定位配置信息发送至终端或者通过定位服务器将定位配置信息发送至终端，以使所述终端可以根据定位配置信息计算定位测量量，使得定位服务器可以根据定位测量量得到终端的目标位置信息，以提供定位精度。

步骤102，根据所述定位配置信息，计算定位测量量。
具体的，在上述步骤102中，终端可以根据基站或者服务器发送的定位配置信息，计算定位测量量。其中，如果定位配置信息包括定位参考信号配置信息，则终端可以根据定位参考信号配置信息计算定位测量量；如果所述定位配置信息包括定位参考信号配置信息以及第一频率层误差参数，则终端可以根据定位参考信号配置信息以及所述第一频率层误差参数计算更为精确的定位测量量。
步骤103，将所述定位测量量上报至定位服务器；其中，所述定位测量量的上报方式可以是：终端针对一个发送接收节点TRP的多个频率层上报一个定位测量量，或者终端针对一个TRP的每个频率层上报一个定位测量量。具体的，在上述步骤103中，终端可以针对一个TRP的每个频率层上报一个定位测量量，或者终端可以针对一个TRP的多个频率层上报一个定位测量量，或者终端可以针对一个TRP的所有频率层上报一个定位测量量，其他TRP均按照上述上报方式进行上报，在此不做赘述。
例如：针对一个TRP配置6个(即M为6)定位参考信号频率层(即频率层)，则终端可以针对一个TRP的每一频率层上报一个定位测量量，即对于一个TRP上报6个定位测量量；或者，终端可以针对一个TRP的3个频率层上报一个定位测量量，即对于一个TRP上报2个定位测量量；或者，终端可以针对一个TRP的所有频率层上报一个定位测量量，即对于一个TRP上报1个定位测量量。
在本公开实施例中，在终端接收到包括定位参考信号配置信息和第一频率层误差参数中的至少一项的定位配置信息的情况下，可以根据上述定位配置信息计算定位测量量，终端向定位服务器针对每一个TRP的多个频率层上报一个定位测量量，或者终端向定位服务器针对每一个TRP的每个频率层均上报一个定位测量量，根据定位配置信息以及终端上报定位测量量的上报方式，定位服务器可以得到较精确的定位测量量，从而可以较精确的定位终端的位置，从而提升定位精度。
可选的，在所述步骤101之前，所述方法还可以包括：

接收所述定位服务器发送的频率层聚合指示信息。
进一步的，所述频率层聚合能力信息可以包括但不限于以下至少一项：聚合频率层数量、是否支持频率层聚合以及接收滤波带宽。
进一步的，所述频率层聚合指示信息可以包括：指示所述终端是否进行频率层聚合、频率层聚合上报方式以及指示用于聚合的频率层索引。
进一步的，所述频率层聚合上报方式可以包括以下任意一项：
针对一个发送接收节点TRP的多个频率层上报一个定位测量量；
针对一个TRP的每个频率层上报一个定位测量量。
具体的，终端频率层聚合上报的方式可以是针对一个TRP的每个频率层上报一个定位测量量，或者终端频率层聚合上报的方式可以是针对一个TRP的多个频率层上报一个定位测量量，或者终端频率层聚合上报的方式可以是针对一个TRP的所有频率层上报一个定位测量量。
具体的，终端向定位服务器发送频率层聚合能力信息，定位服务器根据频率层聚合能力信息，可以得知需要聚合的频率层数量、终端是否支持频率层聚合、终端可以接收的滤波带宽等，以便定位服务器可以根据终端的频率 层聚合能力指示终端是否进行频率层聚合、采用的频率层聚合上报方式以及指示用于聚合的频率层索引等，在此不做具体限定。
例如：定位服务器可以在信令中定义一个频率层聚合指示信息，定义频率层聚合指示信息为ON状态表示终端可以进行频率层聚合，如果终端可以进行频率层聚合，则终端可以根据定位配置信息进行频率层聚合，得到定位测量量，并将定位测量量上报至定位服务器。
可选的，在上述接收所述定位服务器发送的频率层聚合指示信息的步骤之后，所述步骤103具体可以包括：
根据所述频率层聚合指示信息，将所述定位测量量上报至所述定位服务器。
具体的，在终端接收到频率层聚合指示信息的情况下，如果终端可以进行频率层聚合，则终端可以根据定位配置信息进行频率层聚合，得到定位测量量，并按照所述频率层聚合指示信息中的频率层聚合上报方式，将定位测量量上报至定位服务器。
例如：如果终端接收到的频率层聚合指示信息指示终端进行频率层聚合上报方式为：针对一个发送接收节点TRP的多个频率层上报一个定位测量量，则终端根据定位配置信息计算补偿后的定位测量量，并针对一个TRP的多个频率层反馈一个补偿后的定位测量量；如果终端接收到的频率层聚合指示信息指示终端进行频率层聚合上报方式为：针对一个TRP的每个频率层上报一个定位测量量，则终端根据定位配置信息计算定位测量量，并针对一个TRP的每一个频率层反馈一个定位测量量。
可选的，在所述定位配置信息包括：所述第一频率层误差参数和所述定位参考信号配置信息的情况下，所述步骤102具体可以包括：
根据所述定位参考信号配置信息和所述第一频率层误差参数，对不同频率层的定位参考信号进行误差补偿，得到补偿后的定位参考信号；
根据补偿后的定位参考信号，计算定位测量量。
具体的，如果终端需要针对一个TRP的多个频率层上报一个定位测量量，则定位服务器或者基站发送的定位配置信息包括第一频率层误差参数和定位参考信号配置信息，终端可以根据第一频率层误差参数以及定位参考信号配置信息对不同频率层的定位参考信号进行误差补偿，从而得到补偿后的定位 参考信号，终端根据补偿后的定位参考信号可以计算出较为精确的定位测量量，以使定位服务器可以根据较为精确的定位测量量得到终端较为精确的目标位置信息，从而实现对终端位置的精确定位，从而提升定位精度。其中，所述第一频率层误差参数包括不同频率层之间的误差，可以是基站进行上下行传输时，在接收上行信号时获得并发送至终端的，或者，所述第一频率层误差参数可以是基站进行上下行传输时，在接收上行信号时获得并通过定位服务器转发至终端的，第一频率层误差参数的获取方式并不限定。
例如：所述定位配置信息是定位服务器发送至终端，如果终端需要针对一个TRP的所有频率层上报一个定位测量量，换句话说，所述定位测量量是由终端根据对M个定位参考信号频率层传输的定位参考信号测量获得。对于一个TRP，定位服务器的第一频率层误差参数配置了M-1个频率误差，所述M-1个频率误差是其余M-1个定位参考信号频率层(即频率层)相对于目标频率层(例如：第一个频率层)的频率偏移。终端测量M个频率层的PRS信号，并对第二个至第M个频率层的PRS参考信号分别进行误差补偿(如：频率补偿)。例如：将其中每个频率层的PRS信号分别进行对应的频率偏移补偿，补偿的方式可以是对每个频率层PRS信号频率除以对应的频率偏移，补偿的方式仅为示例，并不具体限定。经过补偿后的M个频率层的PRS信号可以等效为一个完整的宽带PRS信号，进行定位测量量的估计和计算，从而得到一个较高精度的定位测量量。其他TRP的定位测量量的计算过程与上述过程类似，在此不做具体限定。
可选的，在所述步骤101之后，所述方法还可以包括：
测量基站发送的不同频率层的定位参考信号，得到测量结果；
根据所述测量结果，获取不同频率层之间的第二频率层误差参数；
将所述第二频率层误差参数发送至所述定位服务器或者所述基站。
具体的，如果终端需要针对一个TRP的每个频率层上报一个定位测量量、且所述终端接收到的定位配置信息不包含第一频率层误差参数，则终端可以测量基站发送的不同频率层的定位参考信号，得到测量结果，终端根据对定位参考信号的测量结果，得到不同频率层之间的第二频率层误差参数。
例如：所述定位配置信息是定位服务器发送至终端，如果终端针对一个TRP的每个频率层上报一个定位测量量，换句话说，每一个定位测量量是由 终端根据对一个定位参考信号频率层传输的定位参考信号测量获得。如果所述终端将所述第二频率层误差参数发送至定位服务器，则定位服务器可以根据所述第二频率层误差参数对接收到的定位测量量进行误差补偿，以得到补偿后的更加精确的定位测量量，从而可以进一步得到较为精确的终端的目标位置信息。如果所述终端将所述第二频率误差参数发送至所述基站，基站可以将所述第二频率层误差参数转发至所述定位服务器，以使所述定位服务器可以得到较为精确的终端的目标位置信息。
进一步的，所述第二频率层误差参数可以包括但不限于以下至少一项：不同频率层间的定时偏移、相位偏移、频率误差、功率偏移。
可选的，在所述根据所述测量结果，获取不同频率层之间的第二频率层误差参数之后，所述方法还可以包括：
综上所述，本公开实施例中，在终端接收到定位配置信息的情况下，终端可以根据上述定位配置信息计算定位测量量；或者终端将频率层聚合能力信息发送至定位服务器，定位服务器可以根据频率层聚合能力信息向终端发送频率层聚合指示信息，终端可以根据上述定位配置信息以及频率层聚合指示信息计算定位测量量；终端可以向定位服务器针对每一个TRP的多个频率层上报一个定位测量量，终端也可以向定位服务器针对每一个TRP的每个频率层均上报一个定位测量量，由于定位配置信息以及终端上报定位测量量的上报方式，定位服务器可以得到较精确的定位测量量，从而可以较精确的得到终端的目标位置信息，从而提升定位精度。

下面通过具体实施例对上述定位方法进行详细说明：
实施例一：
如图3所示，步骤a1，终端向定位服务器发送频率层聚合能力信息，例如：终端可以测量并聚合的频率层数量(如：4个)等。
步骤a2，基站确定定位配置信息中的第一频率层误差参数和定位参考信号配置信息，并将第一频率层误差参数和定位参考信号配置信息发送至定位服务器。所述定位参考信号配置信息包括：配置M个定位参考信号频率层,每个定位参考信号频率层包含N个TRP，每个TRP下包含S个定位参考信号资源集，且每个定位参考信号资源集中包含T个定位参考信号资源。其中，M、N、S、T均为正整数。
所述定位配置信息中包含的M个定位参考信号频率层之间的第一频率层误差参数是用于补偿不同频率层之间的由于器件的原因造成的频率误差、相位误差、功率不平衡等问题。例如：所述第一频率层误差参数包括不同频率层之间的频率误差，频率误差可以通过基站进行上下行传输时，在接收上行信号时估计获得。
步骤a3，定位服务器将定位配置信息中的第一频率层误差参数和定位参考信号配置信息发送至终端。并且，定位服务器可以根据终端发送的频率层聚合能力信息，向终端发送频率层聚合指示信息，指示终端采用频率层聚合上报。例如：定位服务器在信令中定义一个频率层聚合上报指示信息，指示为ON状态时表示终端进行频率层聚合上报。如果终端频率层聚合上报方式是针对一个TRP的所有频率层上报一个定位测量量，则对于前述的一个TRP上报一个定位测量量，该定位测量量由M个定位参考信号频率层传输的定位 参考信号测量获得。
步骤a4，终端根据定位服务器发送的频率层聚合指示信息、定位参考信号配置信息以及第一频率层误差参数，计算每个TRP的一个定位测量量(即补偿后的定位测量量)，将每个TRP的一个定位测量量上报至定位服务器。具体过程可以是：对于其中一个TRP，定位服务器的第一频率层误差参数配置了M-1个频率误差，所述M-1个频率误差是其余M-1个频率层相对于第一个频率层的频率偏移。终端测量M个频率层的PRS信号，并对第二个至第M个频率层的PRS参考信号分别进行频率补偿。例如将其中每个频率层的PRS信号分别进行对应的频率偏移补偿，(补偿方式可以是对每个频率层PRS信号除以所述频率偏移)。经过补偿后的M个频率层的PRS信号可以等效为一个完整的宽带PRS信号，由终端进行定位测量量的估计和计算，得到一个较高精度的定位测量量，并将该定位测量量发送至定位服务器，定位服务器接收到该定位测量量后，进行终端的位置解算，获得终端的目标位置信息，从而提升了定位参考信号带宽，并提升了定位精度。
实施例二：
如图4所示，步骤b1，终端向定位服务器发送频率层聚合能力信息，例如：终端可以测量并聚合的频率层数量(如：4个)等。
步骤b2，基站确定定位配置信息中的定位参考信号配置信息，并将定位参考信号配置信息发送至定位服务器。所述定位参考信号配置信息包括：配置M个定位参考信号频率层，每个定位参考信号频率层包含N个TRP，每个TRP下包含S个定位参考信号资源集，且每个定位参考信号资源集中包含T个定位参考信号资源。其中，M、N、S、T均为正整数。
步骤b3，定位服务器将定位配置信息中的定位参考信号配置信息发送至终端。并且，定位服务器可以根据终端发送的频率层聚合能力信息，向终端发送频率层聚合指示信息，指示终端采用频率层聚合上报。例如：定位服务器在信令中定义一个频率层聚合上报指示信息，指示为ON状态时表示终端进行频率层聚合上报。如果终端频率层聚合上报方式是针对一个TRP的每个频率层上报一个定位测量量，则对于前述的一个TRP上报M个定位测量量，每个定位测量量由一个频率层传输的定位参考信号测量获得。
步骤b4，终端测量基站发送的不同频率层的定位参考信号，并根据定位 服务器发送的频率层聚合指示信息进行不同频率层的频率层误差计算，得到第二频率层误差参数。终端向定位服务器上报每个TRP的不同频率层的多个定位测量量，同时上报每个TRP的第二频率层误差参数。
定位服务器收到所述定位测量量和所述第二频率层误差参数后，对不同频率层的定位测量量进行补偿(如：合并处理)，得到补偿后的定位测量量，补偿后的定位测量量经过位置解算后得到终端的目标位置信息，提升了定位参考信号带宽，也提升了定位精度。
综上所述，本公开上述实施例中，通过第一频率层误差参数或者第二频率层误差参数将多个不同频率层发送的定位参考信号聚合成一个宽带定位参考信号，可以提升定位精度；具体的，多个不同频率层聚合时，各个频率层之间的频率层误差参数由定位服务器配置给终端，或者由终端计算得到并上报至定位服务器，以使定位服务器得到终端较精确的目标位置信息，不仅提升了定位参考信号带宽，也提升了定位精度。
