具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例进行阐述。
在基于定位参考信号(Positioning Reference Signal，PRS)的观测到达时间差(Observed Time Difference Of Arrival，OTDOA)定位方案中，适用的通信系统的结构示意图如图1所示，该通信系统可包括但不限于一个用户设备和三个发送接收节点(Transmission Reception Point，TRP)，图1所示的设备数量和形态用于举例并不构成对本申请实施例的限定，实际应用中可以包括三个以上的TRP，两个或两个以上的用户设备。图1所示的通信系统以一个用户设备101和三个TRP102为例进行阐述，三个TRP102中的任一TRP可向用户设备101发送PRS资源。
本申请中，用户设备也可以称为终端设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、用户代理或用户装置。本申请的实施例中的用户设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
本申请中，网络设备是连接到网络中的物理实体，网络设备可以是基站或核心网网络单元，基站可以是5G基站(gNB)，网络设备也可以是后续演进通信系统中的网络设备。
基于图1的通信系统，以用户设备为手机，TRP为基站，基站的数量为三个，分别为基站A、基站B以及基站C为例。当网络设备需要对用户设备(User Equipment，UE)进行定位时，基站A、基站B以及基站C分别向UE发送周期定位参考信号(Periodic Positioning Reference Signal，P-PRS)资源，若UE 将基站A看为主基站，将基站B和基站C看为副基站，则UE利用接收到的三个P-PRS资源，确定到基站B和基站C的两个参考信号时间差(Reference Signal Time Difference，RSTD)测量结果，并将两个RSTD测量结果上报网络设备；则网络设备将该两个RSTD测量结果换算成UE到基站B和基站C之间的距离的差，进而结合基站B和基站C的位置坐标，利用位置估计算法，计算得到UE的位置坐标，实现对UE的定位。然而，当UE移动且P-PRS的周期还未到时，就无法获得PRS的最新测量结果，从而造成基于PRS的OTDOA定位的定位精度低、定位时延大。
为解决上述问题，本申请提出一种定位参考信号接收方法，用户设备UE接收非周期定位参考信号A-PRS指示信息；然后用户设备根据A-PRS指示信息，确定每个TRP被触发的A-PRS资源集；进而用户设备在每个TRP被触发的A-PRS资源集中各A-PRS资源上进行接收，以获得接收的各PRS的测量结果。该方法中，UE在每个TRP被触发的A-PRS资源集中各A-PRS资源上进行接收，获得了各PRS的测量结果，实现了对A-PRS资源的接收，可增强PRS资源，进而提高基于PRS的OTDOA定位的定位精度和降低定位时延。
本申请提出的技术方案可以应用于各种通信系统，比如，全球移动通信系统、LTE频分双工系统、LTE时分双工系统、通用移动通信系统、新无线系统以及后续演进的通信系统等。
为便于理解本申请公开的实施例，首先对本申请实施例涉及的一些概念进行阐述。这些概念的阐述包括但不限于以下内容。
A-PRS指示信息用于指示接收发送节点TRP所关联的A-PRS资源集是否被触发。TRP为发送A-PRS资源集的基站。A-PRS指示信息包括多个指示，一个指示用于指示一个接收发送节点TRP所关联的各非周期定位参考信号A-PRS资源集是否被触发。
基于上述描述，本申请实施例提出一种如图2所示的定位参考信号接收方法，该方法可以包括S201-S203：
S201：用户设备接收非周期定位参考信号A-PRS指示信息。
A-PRS指示信息可以由下行控制信息DCI携带，即网络设备通过下行控 制信道将DCI发送至UE，UE通过接收DCI，进而接收到A-PRS指示信息。网络设备可以是基站或核心网网络单元，基站可以是5G基站(gNB)，网络设备也可以是后续演进通信系统中的网络设备。
A-PRS资源的配置结构如图3所示，UE可接收多个TRP发送的多个A-PRS资源集，一个TRP可关联一个或多个A-PRS资源集，每个A-PRS资源集包括一个或多个A-PRS资源。比如，在图3中，TRP1所关联的A-PRS资源集有三个A-PRS资源集。A-PRS资源的配置增加了PRS资源配置的灵活性，可增强PRS资源。
一个指示可以以比特位图(bitmap)的方式分别指示一个TRP所关联的各A-PRS资源集是否被触发，也可以以比特(bit)的方式分别指示一个TRP所关联的各A-PRS资源集是否被触发。下面分别对两种方式进行说明。
在一种实现方式中，如图4a所示，多个指示中，一个指示以比特位图的方式分别指示一个TRP所关联的各A-PRS资源集是否被触发，且一个指示包括多个比特，一个比特用于指示一个A-PRS资源集是否被触发，该A-PRS资源集是该指示对应的TRP所关联的一个A-PRS资源集。示例性的，如图5a所示，A-PRS指示信息包括四个指示，每个指示对应一个比特位图，分别用于指示TRP-A、TRP-B、TRP-C以及TRP-D所关联的A-PRS资源集是否被触发，TRP-A对应的bitmap#a包括三个比特，分别为比特A、比特B以及比特C，每个比特用于指示TRP-A的一个A-PRS资源集是否被触发。比特位图中的一个比特用于指示一个A-PRS资源集的方式，可使得A-PRS指示信息中的指示精细。
在又一种实现方式中，如图4b所示，多个指示中，一个指示占用一个比特，一个比特用于指示该指示对应的TRP所关联的全部A-PRS资源集是否被触发。示例性的，如图5b所示，A-PRS指示信息包括三个比特，分别用于指示TRP-A、TRP-B以及TRP-C每个TRP所关联的全部A-PRS资源集是否被触发，比如，TRP-A所关联的A-PRS资源集包括A-PRS资源集A、A-PRS资源集B以及A-PRS资源集C，比特A用于指示TRP-A所关联的A-PRS资源集A、A-PRS资源集B以及A-PRS资源集C是否被触发。一个比特指示一个TRP所关联的全部A-PRS资源集是否被触发的方式可节约资源开销。
在一种实现方式中，用户设备接收非周期定位参考信号A-PRS指示信息之前，还可以获取多个A-PRS资源集的配置信息，配置信息用于指示各A-PRS资源集中的各A-PRS资源的时频资源。
S202：用户设备根据A-PRS指示信息，确定每个TRP被触发的A-PRS资源集。
用户设备通过确定A-PRS指示信息中的各比特的值，确定每个TRP被触发的A-PRS资源集。
在一种实现方式中，一个指示包括多个比特，当一个比特的值为1时，该比特指示的A-PRS资源集被触发，当一个比特的值为0时，该比特指示的A-PRS资源集未被触发，该A-PRS资源集为该比特对应的TRP的一个A-PRS资源集。当一个A-PRS资源集被触发时，意味着用户设备可在该A-PRS资源集的资源上进行接收，以获得接收的各PRS测量结果。在此，对比特指示的一个A-PRS资源集被触发时所对应的比特值不做限定。比如，当一个比特的值为0时，该比特指示的A-PRS资源集被触发，当一个比特的值为1时，该比特指示的A-PRS资源集未被触发。
以一个比特的值为1时，该比特指示的A-PRS资源集被触发为例，在图5a中，若比特A指示的A-PRS资源集为A-PRS资源集A，当比特A的值为1时，用户设备确定A-PRS资源集A被触发，该A-PRS资源集A为比特A指示的TRP-A中的一个A-PRS资源集。
在一种实现方式中，一个指示占用一个比特，当一个比特的值为1时，与该比特对应的TRP所关联的全部A-PRS资源集被触发，当一个比特的值为0时，该比特对应的TRP所关联的全部A-PRS资源集未被触发。当一个TRP所关联的全部A-PRS资源集被触发时，意味着用户设备可在该TRP所关联的全部A-PRS资源集的资源上进行接收，以获得接收的各PRS测量结果。在此，对比特指示的一个A-PRS资源集被触发时所对应的比特值不做限定。比如，当一个比特的值为0时，该比特对应的TRP的全部A-PRS资源集被触发，当一个比特的值为1时，该比特对应的TRP所关联的全部A-PRS资源集未被触发。
以一个比特的值为1时，与该比特对应的TRP所关联的全部A-PRS资源 集被触发为例，在图5b中，比特A对应的TRP为TRP-A，TRP-A所关联的A-PRS资源集包括A-PRS资源集A、A-PRS资源集B以及A-PRS资源集C，当比特A的值为1时，A-PRS资源集A、A-PRS资源集B以及A-PRS资源集C都被触发。
S203：用户设备在每个TRP被触发的A-PRS资源集中各A-PRS资源上进行接收，以获得接收的各PRS测量结果。
用户设备根据A-PRS指示信息确定的每个TRP被触发的A-PRS资源集，在每个TRP被触发的A-PRS资源集中各A-PRS资源上进行接收，以获得接收的各PRS的测量结果，PRS的测量结果为用户设备对A-PRS中的A-PRA资源进行接收时得到的RSTD。
在一种实现方式中，用户设备获得了多个A-PRS资源集的配置信息，配置信息中包括了用于指示各A-PRS资源集中的各A-PRS资源的时频资源。因此，用户设备根据配置信息中指示每个TRP被触发的A-PRS资源集的各A-PRS资源的时频资源，在每个TRP被触发的A-PRS资源集中各A-PRS资源上进行接收，以获得接收的各PRS测量结果。
在一种实现方式中，用户设备在每个TRP被触发的A-PRS资源集中的A-PRS资源上进行接收，以获得接收的各PRS的测量结果之后，用户设备还可以根据各个PRS的测量结果的质量好坏，将多个PRS的测量结果中的至少两个PRS测量结果上报给网络设备，至少两个PRS的测量结果用于估计UE的位置坐标。其中，PRS的测量结果的质量好坏是根据A-PRS资源的好坏决定的，比如，用户设备接收的多个A-PRS资源中的第一A-PRS资源的信噪比较大，则用户设备接收到的第一A-PRS的测量结果的质量差，不将该第一A-PRS的测量结果上报给网络设备，直接丢弃该第一A-PRS的测量结果。
在本申请实施例中，用户设备根据接收的A-PRS指示信息，确定每个TRP被触发的A-PRS资源集，并在每个TRP被触发的A-PRS资源集中各A-PRS资源上进行接收，以获得接收的各PRS的测量结果。该方法使得用户设备可在该用户设备移动且P-PRS资源未到达时，触发接收A-PRS资源，从而提高基于PRS的OTDOA定位的定位精度和降低定位时延。
以上实施例为从用户设备侧触发，体现用户设备可根据A-PRS指示信息 确定每个TRP被触发的A-PRS资源集，并在被触发的A-PRS资源集的A-PRS资源上进行接收，获得各PRS测量结果。下面从网络设备的角度详细描述A-PRS指示信息的配置，提出如图6所示的一种定位参考信号发送方法，该方法包括：S601-S602。
S601：网络设备确定非周期定位参考信号A-PRS指示信息。
A-PRS指示信息请见上述所述，在此不再赘述。
在一种实现方式中，网络设备确定在多个指示中，一个指示以比特位图的方式分别指示一个TRP所关联的各A-PRS资源集是否被触发，且一个指示包括多个比特，一个比特用于指示一个A-PRS资源集是否被触发，该A-PRS资源集是该指示对应的TRP所关联的一个A-PRS资源集。A-PRS指示信息的结构示意图可参见上图4a所示。网络设备可确定一个比特的值为1时，该比特指示的A-PRS资源集被触发，确定一个比特的值为0时，该比特指示的A-PRS资源集被触发未被触发。可选的，网络设备也可确定一个比特的值为0时，该比特指示的A-PRS资源集被触发，确定一个比特的值为1时，该比特指示的A-PRS资源集被触发未被触发。该确定方法中，网络设备确定一个比特只指示该指示对应的TRP所关联的一个A-PRS资源集，可使得每个比特指示的资源集更精细，可实现网络设备向用户设备只发送一个TRP所关联的一部分A-PRS资源集。
在一种实现方式中，网络设备确定在多个指示中，一个指示占用一个比特，一个比特用于指示该指示对应的TRP所关联的全部A-PRS资源集是否被触发。A-PRS指示信息的结构示意图可参见上图4b所示。网络设备通过一个比特的值确定该比特指示的所有A-PRS资源集是否被触发的方式可参见上述，不再赘述。该确定方法中，网络设备确定一个比特用于指示该指示对应的TRP所关联的全部A-PRS资源集，可节约资源开销。
网络设备确定非周期定位参考信号A-PRS指示信息的方式，增加了A-PRS资源的配置，从而增强了PRS资源，可提高基于PRS的OTDOA定位的定位精度和减少定位时延。
S602：网络设备将A-PRS指示信息和被触发的A-PRS资源集中的A-PRS资源发送至用户设备。
网络设备将A-PRS指示信息和被触发的A-PRS资源集中的A-PRS资源发送至UE，以使得UE获得接收的多个PRS测量结果。
A-PRS指示信息由DCI携带，网络设备在确定A-PRS指示信息时，会确定DCI中的每个指示对应的TRP。因此网络设备确定A-PRS指示信息中一个指示对应的A-PRS资源集被触发后，则该指示所对应的TRP将该指示对应的被触发的A-PRS资源集发送至用户设备。
在一种实现方式中，网络设备将A-PRS指示信息和被触发的A-PRS资源集中的A-PRS资源发送至用户设备UE之后，还可以接收UE发送的至少两个PRS的测量结果，至少两个PRS的测量结果用于估计UE的位置坐标。该方式使得网络设备可利用接收到的至少两个PRS测量结果估计UE的位置坐标，实现对UE的定位。
在本申请实施例中，网络设备确定了A-PRS指示信息，并将指示信息和被触发的A-PRS资源集发送至UE，使得UE可根据A-PRS指示信息在被触发的A-PRS资源集中的A-PRS资源上进行接收。因此，若UE移动且P-PRS资源的周期未到，则可根据A-PRS指示信息在被触发的A-PRS资源集中的A-PRS资源上进行接收，从而提高基于PRS的OTDOA定位的定位精度和降低定位时延。
结合以上图2和图6的实施例，下面同时从用户设备和网络设备两个方面出发，提出如图7所示的一种定位参考信号交互方法，该方法包括：S701-S705。
S701：网络设备确定非周期定位参考信号A-PRS指示信息。
S702：网络设备将A-PRS指示信息和被触发的A-PRS资源集中的A-PRS资源发送至用户设备。
本申请实施例中的S701-S702具体可参见上述实施例中S601-S602的执行过程，本发明实施例不再赘述。
S703：用户设备根据A-PRS指示信息，确定每个TRP被触发的A-PRS资源集。
本申请实施例中的S703具体可参见上述实施例中S302的执行过程，本发明实施例不再赘述。
S704：用户设备在每个TRP被触发的A-PRS资源集中各A-PRS资源上进 行接收，以获得多个PRS测量结果。
用户设备根据确定的每个TRP被触发的A-PRS资源集，在每个TRP被触发的A-PRS资源集中各A-PRS资源上进行接收A-PRS资源。网络设备发送A-PRS资源集中个各A-PRS资源的资源和用户设备接收A-PRS资源集中个各A-PRS资源的资源会存在时延。
S705：用户设备将多个PRS的测量结果中的至少两个PRS测量结果上报给网络设备。
用户设备根据各个PRS的测量结果的质量好坏，将多个PRS的测量结果中的至少两个PRS测量结果上报给网络设备，至少两个PRS的测量结果用于估计UE的位置坐标。其中，PRS的测量结果的质量好坏是根据A-PRS资源的好坏决定的。比如A-PRS资源的信噪比越小，该A-PRS资源的质量越好，进而用户设备获得的该A-PRS资源对应的PRS测量结果的质量越好。
S706：网络设备根据至少两个PRS的测量结果，估计UE的位置坐标。
网络设备根据接收到的至少两个PRS的测量结果估计UE的位置坐标，实现对UE的定位。
在本申请实施例中，网络设备确定了A-PRS指示信息，并将A-PRS指示信息发送至了网络设备，因此用户设备接收A-PRS指示信息，并根据A-PRS指示信息确定每个TRP被触发的A-PRS资源集，在每个TRP被触发的A-PRS资源集中的A-PRS资源上进行接收，获得多个PRS测量结果，最后根据PRS测量结果的质量好坏，将至少两个PRS测量结果发送至网络设备，使得网络设备根据至少两个PRS测量结果估计UE的位置坐标。该方法中，网络设备确定了A-PRS指示信息，增强了A-PRS资源。UE根据A-PRS指示信息，在被触发的A-PRS资源集中的A-PRS资源上进行接收，获得了接收的各PRS测量结果，因此可提高基于PRS的OTDOA定位的定位精度。

在一种实现方式中，A-PRS指示信息由下行控制信息DCI携带。
在一种实现方式中，处理单元802，还用于接收非周期定位参考信号A-PRS指示信息之前，获取多个A-PRS资源集的配置信息，配置信息用于指示各A-PRS资源集中的各A-PRS资源的时频资源；根据配置信息，在每个TRP被触发的A-PRS资源集中的A-PRS资源上进行接收。
在一种实现方式中，处理单元802，还用于在每个TRP被触发的A-PRS资源集中的A-PRS资源上进行接收，以获得接收的各PRS的测量结果之后，将多个PRS的测量结果中的至少两个PRS测量结果上报给网络设备，至少两个PRS的测量结果用于估计所述UE的位置坐标。
