需要说明的是，下文仅以NR系统为例说明本公开实施例提供的定位参考信号配置、接收方法及装置，应理解，本公开实施例提供的定位参考信号配置、接收方法及装置还可以应用于其他通信系统，并不局限于NR系统。
下面先结合附图1至3，对应用于网络设备的定位参考信号配置方法进行说明。
图1示出了根据本公开一个实施例的定位参考信号配置方法，应用于网络设备。如图1所示，该方法可以包括如下步骤：
步骤101、基于定位参考信号PRS与特定下行信号之间的空间准共址QCL关系，发送配置信息，所述配置信息用于确定所述PRS与所述特定下行信号占用的资源。
其中，特定下行信号包括下行系统公共信号或系统公共信道，例如，所述特定下行信号包括下列信号中的一种或多种：信道状态参考信号(Channel State Information-Reference Signals，CSI-RS)、物理下行共享信道(Physical Downlink Shared Channel，PDSCH)、物理下行控制信道(Physical Downlink Control Channel，PDCCH)和同步信号块(Synchronization Signal Block，SSB)等系统公共信号或系统共信道。
下面对准共址(Quasi Co-location，QCL)关系进行简要的介绍。
具体来说，如果两个天线端口的信号满足QCL关系，那么两组信号经历的信道的多普勒频移、多普勒扩展、平均时延、时延扩展和空间接收参数等参数中的至少一项近似相同。QCL关系可以包括如下几种类型：
QCL类型A(QCL-TypeA)：{多普勒频移，多普勒扩展，平均延迟，延迟扩展}
QCL类型B(QCL-TypeB)：{多普勒频移，多普勒扩展}
QCL类型C(QCL-TypeC)：{平均延迟，多普勒频移}
QCL类型D(QCL-TypeD)：{空间Rx参数}。
一般而言，如果PRS与特定下行信号之间具有空间QCL关系，则上述配置信息包括：PRS与特定下行信号可占用相同的(或者说同一个)正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号。当然，如果PRS与特定下行信号之间具有空间QCL关系，上述配置信息也可以包括：PRS与特定下行信号可占用不同的OFDM符号。如果PRS与特定下行信号之间不具有空间QCL关系，则上述配置信息包括：PRS与特定下行信号占用不同的OFDM符号。下面会通过更为具体实施例对PRS与特定下行信号占用的资源进行说明，详见下文。
可以理解，网络设备配置PRS与特定下行信号占用同一OFDM符号，或者网络设备配置PRS与特定下行信号占用不同的OFDM符号，意在配置PRS与特定下行信号复用或不复用下行时域资源，也即意在配置PRS是否要避免与特定下行信号发生碰撞。
本公开实施例提供的定位参考信号配置方法，由于网络设备发送的用于确定所述PRS与特定下行信号占用的资源的配置信息，使得终端设备可以明确PRS与特定下行信号有没有复用下行时域资源，从而正确接收PRS，进而可以依据接收到的PRS实现终端设备的定位，提高了通信有效性。
下面结合更为具体的实施例对网络设备发送的配置信息包含的内容进行说明。
在一个实施例中，假设所述特定下行信号包括所述CSI-RS。
则作为一个例子，当所述PRS与所述CSI-RS之间具有空间QCL关系时，所述配置信息包括：所述PRS与所述CSI-RS占用同一正交频分复用OFDM符号。也即，PRS与CSI-RS可复用相同的时域资源，这意味着终端设备可同时接收PRS和CSI-RS。
具体来说，所述PRS与所述CSI-RS占用同一正交频分复用OFDM符号，可包括：所述PRS与所述CSI-RS频分复用同一OFDM符号上的不同资源粒子RE；或者，当在所述OFDM符号中的同一RE上发送所述PRS与所述CSI-RS时，所述PRS与所述CSI-RS共用所述同一RE。
作为另一个例子，当所述PRS与所述CSI-RS之间不具有空间QCL关系时，所述配置信息包括：所述PRS与所述CSI-RS占用不同的OFDM符号。 也即，PRS与CSI-RS不复用相同的时域资源，这意味着在同一时刻，终端设备只接收PRS或只接收CSI-RS。
在上述两个例子中，所述CSI-RS可以包括下列信息中的一种或多种：①用于跟踪的CSI-RS(CSI-RS for tracking)，例如，跟踪参考信号(Tracking Reference Signal，TRS)；②用于计算物理层(L1)参考信号接收功率(Reference Signal Receiving Power，RSRP)的CSI-RS，也即CSI-RS for L1-RSRP computation；③用于移动性的CSI-RS(CSI-RS for mobility)，等等。
在本实施例中，由于网络设备发送的用于确定所述PRS与CSI-RS占用的资源的配置信息，使得终端设备可以明确PRS与CSI-RS有没有复用下行时域资源，从而正确接收PRS，进而可以依据接收到的PRS实现终端设备的定位，提高了通信有效性。
在另一个实施例中，假设所述特定下行信号包括所述PDSCH。
则作为一个例子，当所述PRS与所述PDSCH之间具有空间QCL关系时，所述配置信息包括：所述PRS与所述PDSCH占用同一正交频分复用OFDM符号。这意味着，PRS与PDSCH可复用相同的时域资源，网络设备可在同一OFDM符号上发送PRS和PDSCH，相应的，终端设备可同时接收PRS和PDSCH。
在该例子中，所述PRS与所述PDSCH占用同一OFDM符号，具体可以包括：对所述PDSCH围绕所述PRS进行速率匹配，或当在所述OFDM符号中的同一RE上发送所述PRS与所述PDSCH时，映射在所述RE上的所述PDSCH被所述PRS打孔(PDSCH are punctured by PRS)。
其中，映射在所述RE上的所述PDSCH被所述PRS打孔，是指将映射在所述RE上的PDSCH打掉，而将所述PRS映射在所述RE上。
其中，对所述PDSCH围绕所述PRS进行速率匹配，是指将所述PRS映射在所述RE上，在所述PRS占用的RE以外的RE上映射所述PDSCH。
作为另一个例子，当所述PRS与所述PDSCH之间具有空间QCL关系时，所述配置信息也可以包括：所述PRS与所述PDSCH占用不同的OFDM符号。其中，所述PRS与所述PDSCH占用不同的OFDM符号，具体可包括：所述PRS与所述PDSCH占用同一时隙内的不同OFDM符号；或者，所述PRS与 所述PDSCH占用不同时隙内的OFDM符号，即在发送PRS的时隙中不发送PDSCH。
这意味着，所述PRS与所述PDSCH之间具有空间QCL关系时，PRS与PDSCH也可不复用相同的时域资源，网络设备在一个或多个OFDM符号上只发送PRS不发送PDSCH，相应的，在同一时刻，终端设备只接收PRS。
作为又一个例子，当PRS与所述PDSCH之间不具有空间QCL关系时，所述配置信息包括：所述PRS与所述PDSCH占用不同的OFDM符号。这意味着，PRS与PDSCH不复用相同的时域资源，网络设备在一个或多个OFDM符号上只发送PRS不发送PDSCH；或者，网络设备在一个或多个OFDM符号上只发送PDSCH不发送PRS。相应的，在同一时刻，终端设备只接收PRS或只接收PDSCH。
在本实施例中，由于网络设备发送的用于确定所述PRS与PDSCH占用的资源的配置信息，使得终端设备可以明确PRS与PDSCH有没有复用下行时域资源，从而正确接收PRS，进而可以依据接收到的PRS实现终端设备的定位，提高了通信有效性。
在另一个实施例中，假设所述特定下行信号包括所述PDCCH。
则作为一个例子，当所述PRS与所述PDCCH之间具有空间QCL关系时，所述配置信息包括：所述PRS与所述PDCCH占用同一正交频分复用OFDM符号。这意味着，PRS与PDCCH可复用相同的时域资源，网络设备可在同一OFDM符号上发送PRS和PDCCH，相应的，终端设备可同时接收PRS和PDCCH。
在该例子中，所述PRS与所述PDCCH占用同一OFDM符号具体可包括：对所述PDCCH围绕所述PRS进行速率匹配，或当在所述OFDM符号中的同一RE上发送所述PRS与所述PDCCH时，映射在所述RE上的所述PDCCH被所述PRS打孔。
其中，映射在所述RE上的所述PDCCH被所述PRS打孔，是指将映射在所述RE上的PDCCH打掉，而将所述PRS映射在所述RE上。
其中，对所述PDCCH围绕所述PRS进行速率匹配，是指将所述PRS映射在所述RE上，在所述PRS占用的RE以外的RE上映射所述PDCCH。
或者，作为另一个例子，当所述PRS与所述PDCCH之间具有空间QCL关系时，所述配置信息也可以包括：所述PRS与所述PDCCH占用不同的OFDM符号。这意味着，所述PRS与所述PDCCH之间具有空间QCL关系时，PRS与PDCCH也可不复用相同的时域资源，网络设备可配置不在PDCCH占用的OFDM符号上发送PRS，相应的，在同一时刻，终端设备不在PDCCH占用的OFDM符号上接收PRS。
作为又一个例子，当所述PRS与所述PDCCH之间不具有空间QCL关系时，所述配置信息包括：所述PRS与所述PDCCH占用不同的OFDM符号。
这意味着，PRS与所述PDCCH之间不具有空间QCL关系时，PRS与PDCCH不复用相同的时域资源，网络设备可配置不在PDCCH占用的OFDM符号上发送PRS，相应的，在同一时刻，终端设备只接收PDCCH。
在本实施例中，由于网络设备发送的用于确定所述PRS与PDCCH占用的资源的配置信息，使得终端设备可以明确PRS与PDCCH有没有复用下行时域资源，从而正确接收PRS，进而可以依据接收到的PRS实现终端设备的定位，提高了通信有效性。
在另一个实施例中，假设所述特定下行信号包括SSB。
则作为一个例子，当所述PRS与所述SSB之间具有空间QCL关系，以及所述PRS与所述SSB具有相同的子载波间隔时，所述配置信息包括：所述PRS与所述SSB占用同一正交频分复用OFDM符号。
在该例子中，网络设备配置所述PRS与所述SSB占用同一OFDM符号的方式可以是下列方式中的任一种：
①所述PRS与所述SSB中的物理广播信道PBCH占用所述OFDM符号中频域位置不同的资源块(Resource Block，RB)，或者说，所述PRS占用所述OFDM符号中频域位置在所述SSB中的物理广播信道PBCH占用的RBs外部的资源块RBs上。
SSB可以包括：主同步信号(Primary Synchronization Signal，PSS)、辅同步信号(Secondary Synchronization Signal，SSS)、物理广播信道(Physical Broadcast Channel，PBCH)和物理广播信道解调参考信号(Physical Broadcast Channel-Demodulation Reference Signal，PBCH-DMRS)等信号。
该方式可以引申为，PRS与SSB占用同一OFDM符号中频域位置不同的RB。例如，请参考图2，图2示出了4个OFDM符号中的资源映射接收示意图。如图2所示，在这4个OFDM符号中映射有NR-PSS、NR-SSS、NR-PBCH和NR-PBCH-DMRS，这4个OFDM符号中共包括20个被SSB占用的RB，网络设备可以将PRS配置在这20个RB外部的RB上，即使第一个OFDM符号没有被SSB占满(图2中没有填充图案的部分)，也要将PRS配置在这20个RB外部的RB上。在图2所示的例子中，一个RB中可包含12个连续的子载波。
②当在所述OFDM符号中的同一RE上发送所述PRS与所述SSB时，映射在所述RE上的所述PRS被所述SSB打孔。
也即，网络设备可配置PRS与SSB占用相同的OFDM符号，且当在所述OFDM符号中的同一RE上发送所述PRS与所述SSB时，将映射在所述RE上PRS打掉，将所述SSB映射在所述RE上。
③当在所述OFDM符号中的同一RE上发送所述PRS与所述SSB时，映射在所述RE上的所述SSB被所述PRS打孔。
也即，网络设备可配置PRS与SSB占用相同的OFDM符号，且当在所述OFDM符号中的同一RE上发送所述PRS与所述SSB时，将映射在所述RE上SSB打掉，将所述PRS映射在所述RE上。
④当在所述OFDM符号中的同一RE上发送所述PRS与所述SSB中的物理广播信道解调参考信号PBCH DMRS时，所述PRS与所述PBCH DMRS共用所述RE，且当在所述OFDM符号中的同一RE上发送所述PRS与除所述PBCH DMRS外的SSB时，映射在所述RE上的所述PRS被除所述PBCH DMRS外的SSB打孔。
也即，网络设备可配置PRS与SSB占用相同的OFDM符号，在所述OFDM符号中的同一RE上发送所述PRS与所述SSB中的PBCH DMRS时，所述PRS与所述PBCH DMRS共用所述RE，且当在所述OFDM符号中的同一RE上发送所述PRS与除所述PBCH DMRS外的SSB时，将映射在所述RE上的所述PRS打掉，将除所述PBCH DMRS外的SSB映射在所述RE上。
⑤当在所述OFDM符号中的同一RE上发送所述PRS与所述SSB中的 物理广播信道解调参考信号PBCH DMRS时，所述PRS与所述PBCH DMRS共用所述RE，且当在所述OFDM符号中的同一RE上发送所述PRS与除所述PBCH DMRS外的SSB时，映射在所述RE上的除所述PBCH DMRS外的SSB被所述PRS打孔。
也即，网络设备可配置PRS与SSB占用相同的OFDM符号，且当在所述OFDM符号中的同一RE上发送所述PRS与所述SSB中的PBCH DMRS时，所述PRS与所述PBCH DMRS共用所述RE，且当在所述OFDM符号中的同一RE上发送所述PRS与除所述PBCH DMRS外的SSB时，将映射在所述RE上的除所述PBCH DMRS外的SSB打掉，将所述PRS映射在所述RE上。
或者，作为另一个例子，当所述PRS与所述SSB之间具有空间QCL关系时，所述配置信息包括：所述PRS与所述SSB占用不同的OFDM符号。这意味着，网络设备配置不在SSB占用的OFDM符号上发送PRS。
作为又一个例子，当所述PRS与所述SSB之间不具有空间QCL关系时，所述配置信息包括：所述PRS与所述SSB占用不同的OFDM符号。也即，如果所述PRS与所述SSB之间不具有空间QCL关系，网络设备配置不在SSB占用的OFDM符号上发送PRS，终端设备只接收SSB。
在本实施例中，由于网络设备发送的用于确定所述PRS与SSB占用的资源的配置信息，使得终端设备可以明确PRS与SSB有没有复用下行时域资源，从而正确接收PRS，进而可以依据接收到的PRS实现终端设备的定位，提高了通信有效性。
以上结合具体的实施例分别对PRS与CSI-RS、PDSCH、PDCCH和SSB的资源占用配置情况进行了说明。下面对网络设备发送上述配置信息的方式进行说明。
在具体配置过程中，网络设备可以基于下列方式中的一种或多种发送所述配置信息：①基于高层信令发送所述配置信息，例如，利用无线资源控制(Radio Resource Control，RRC)消息发送所述配置信息；②基于媒体访问控制(Media Access Control，MAC)层信令发送所述配置信息；或者，③基于下行控制信息(Downlink Control Information，DCI)发送所述配置信息。
当然，在另一实施例中，也可以由协议规定上述配置信息。应理解，当上述配置信息由协议规定时，网络设备可不发送上述配置信息，而是由终端设备通过查询协议获得上述配置信息，并基于上述配置信息接收PRS。
可选地，在另一个实施例中，如图3所示，在上述步骤101的基础上，本公开实施例提供的定位参考信号配置方法，还可以包括：
步骤102、基于所述配置信息，发送所述PRS和所述特定下行信号。
可以理解，在向终端设备发送上述配置信息以后，后续再基于上述配置信息向终端设备发送PRS和上述特定下行信号，可以使终端设备正确的接收PRS和上述特定下行信号，并可以依据接收到的PRS和上述特定下行信号进行下一步地处理，提高了通信有效性。
以上对应用于网络设备的定位参考信号配置方法进行了说明，下面结合图4和图5对本公开实施例提供的应用于终端设备中的定位参考信号接收方法进行说明。
如图4所示，根据本公开一个实施例的定位参考信号接收方法，应用于终端设备，可以包括如下步骤：
步骤401、接收配置信息，所述配置信息由网络设备基于定位参考信号PRS与特定下行信号之间的空间准共址QCL关系发送，所述配置信息用于确定所述PRS与所述特定下行信号占用的资源。
其中，特定下行信号包括下行系统公共信号或系统公共信道，例如，所述特定下行信号包括下列信号中的一种或多种：信道状态信息参考信号CSI-RS、物理下行共享信道PDSCH、物理下行控制信道PDCCH和同步信号块SSB。
本公开实施例提供的定位参考信号接收方法，由于终端设备接收的网络设备发送的用于确定所述PRS与特定下行信号占用的资源的配置信息，使得终端设备可以明确PRS与特定下行信号有没有复用下行时域资源，从而正确接收PRS，进而可以依据接收到的PRS实现终端设备的定位，提高了通信有效性。

其中，当所述PRS与所述PDCCH之间具有空间QCL关系，所述PRS与所述PDCCH占用同一OFDM符号包括：对所述PDCCH围绕所述PRS进行速率匹配，或当在所述OFDM符号中的同一RE上发送所述PRS与所述PDCCH时，映射在所述RE上的所述PDCCH被所述PRS打孔。
在另一个例子中，当所述PRS与所述PDCCH之间不具有空间QCL关系时，所述配置信息包括：所述PRS与所述PDCCH占用不同的OFDM符号。
在另一个实施例中，假如所述特定下行信号包括所述SSB时，在一个例子中，当所述PRS与所述SSB之间具有空间QCL关系，以及所述PRS与所述SSB具有相同的子载波间隔时，所述配置信息包括：所述PRS与所述SSB占用同一正交频分复用OFDM符号；或者，所述PRS与所述SSB占用不同的OFDM符号。
其中，所述PRS与所述SSB占用同一OFDM符号包括如下方式中的一种：

以上结合具体的实施例分别对PRS与CSI-RS、PDSCH、PDCCH和SSB的资源占用配置情况进行了说明。下面对终端设备接收上述配置信息的方式进行说明。
在具体接收过程中，终端设备可以基于下列方式中的一种或多种接收所述配置信息：①基于高层信令接收所述配置信息，例如，基于RRC消息接收所述配置信息；②基于MAC层信令接收所述配置信息；或者，③基于DCI接收所述配置信息。
当然，在另一实施例中，也可以由协议规定上述配置信息。应理解，当上述配置信息由协议规定时，终端设备可不接收来自网络设备的上述配置信息，而是通过查询协议获得上述配置信息，并基于上述配置信息接收PRS。
可选地，在另一个实施例中，如图5所示，在上述步骤401的基础上，本公开实施例提供的定位参考信号接收方法，还可以包括：
步骤402、基于所述配置信息，接收所述PRS和所述特定下行信号。
可以理解，终端设备在接收到上述配置信息以后，后续可以基于上述配置信息正确地接收PRS和上述特定下行信号，并依据接收到的PRS和上述特定下行信号进行下一步地处理，提高了通信有效性。
可选地，在另一个实施例中，终端设备在接收到网络设备配置的PRS之后，还可以进一步基于该PRS进行定位。下面以将PRS应用在观测到达时间(Observed Time Difference of Arrival，OTDOA)定位中为例，对终端设备基于PRS进行定位的过程进行简要的说明。
作为一个例子，OTDOA定位方法基于PRS定位的过程可以包括：
首先，网络设备基于上文中述及的方法生成PRS，并向终端设备发送所述PRS，其中，所述网络设备包括所述终端设备的服务小区和从终端设备附近选出的多个邻小区。
其次，终端设备对来自邻小区的PRS与本地PRS做时域相关，得到每一邻小区对应的时延功率谱。其中，本地PRS是终端设备基于PRS生成规则生 成的PRS。
再次，终端设备根据邻小区对应的时延功率谱寻找该邻小区的首达径，获得每个邻小区发送的PRS到达终端设备的到达时间(Time of Arrival，TOA)。
最后，网络设备基于至少三个邻小区对应的TOA，确定服务小区与每个邻小区的参考信号时差(Reference Signal Time Difference，RSTD)，确定终端设备的位置。具体可以是计算终端设备的坐标。
在上述过程中，终端设备的位置由至少三个邻小区的到达时间差(Time Difference of Arrival，TDOA)来确定，即由相对时间而不是绝对时间确定。
由于本公开实施例提供的定位参考信号接收方法，与本公开实施例提供的定位参考信号配置方法相对应，因此，本说明书对定位参考信号接收方法的描述较为简单，相关之处，请参考上文中对定位参考信号配置方法的描述。
