具体实施方式
下文中将结合附图对本公开的实施例进行详细说明。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
在5G Rel-15阶段，和以前相比增加了很多参考信号，有些和LTE中的定位参考信号有些相似性，但是还没有定义定位参考信号。目前的标准进度中，定义新无线(New Radio，NR)新的定位参考信号和复用一些其他的NR的参考信号两种方式各有利弊，如何保证定位效果，同时不造成不必要的资源开销，又不影响其他参考信号本来的功能是一个难题，急需一个合适的解决方法。
在LTE中，静音(muting)是PRS的一个机制，以减小各个小区间的干扰，不可避免地也会影响某些定位节点的定位性能和时延，利用已有的其他参考信号去弥补这一影响将会是合理的解决方法。

下面以一些应用实例进行说明。
应用实例一
如图6所示，在一个PRS资源集合内有
Figure PCTCN2020083861-appb-000019
个PRS资源，在本应用实例中
Figure PCTCN2020083861-appb-000020
取8，8个PRS资源的索引编号为0至7，该发射节点选择只发送第0、2、4、6个PRS资源，则PRS资源选择序列为10101010。
发射节点将该PRS资源选择序列作为PRS配置信息上报给定位服务器，PRS的配置信息还包括4个PRS资源的序列生成ID，时域起点，频域密度，PRS资源集合的静音配置。
定位服务器将可能被测量的发射节点的PRS的配置信息发送给接收节点，接收节点配置相应的检测时间窗和检测周期去检测参考小区和相邻小区的PRS。
采用OTDOA方式进行定位。
应用实例二
其他场景同应用实例一，但是四个PRS资源集合所提供的覆盖和信号强度并不能满足更高的定位精度要求，同时该发射节点在未选择发送PRS的潜在资源位置有发送其他参考信号，且其配置可以用作定位测量，该其他参考信号即补充参考信号，如图7所示。
发射节点将补充参考信号资源配置信息和PRS配置信息一起上报给定位服务器。定位服务器将上述配置信息发送给接收节点，接收节点根据其配置信息确定检测时间窗，检测周期和检测所用的本地序列对PRS和补充参考信号进行检测进行定位。如图8所示，为补充参考信号资源配置信息的传输流程。
应用实例三
其他场景同应用实例二，参照图9，在该发射节点除发送PRS资源外在其他位置有发送其他参考信号，并不与PRS可用资源完全重叠。且其配置可以用作定位测量，该其他参考信号即为补充参考信号。
应用实例四
PRS资源集合的发送周期为T prs,PRS静音配置周期为六个PRS发送周期，假设有三个PRS资源集合被静音，该发射节点的PRS资源集合静音配置序列为110010，在第3、4、6个PRS发射时段内，由于该节点发PRS发射被静音，所以依赖于该节点所发射信号在对应时段定位将会受到影响。同时该节点有其他参考信号资源集合的配置，能够满足定位需求，与PRS资源集合的周期一样，时域上相差t offset，补充参考信号资源集合的指示序列为111111，如图10所示。
该发射节点将该补充参考信号资源集合配置信息和PRS配置信息发送给定位服务器，定位服务器将所述信息发送给接收节点。接收节点根据所述信息配置检测时间窗和检测周期，在PRS信号被静音的周期内检测补充参考信号以完成定位。接收节点配置检测时间窗能够覆盖补充参考信号资源集合和PRS资源集合，根据补充参考信号和各个发射节点的PRS信号互相到达时间差进行定位。如图11所示，为补充参考信号资源集合配置信息的传输流程。
应用实例五
其他条件同应用实例四，参照图12，补充参考信号资源集合并不是周期性的，补充参考信号资源集合配置信息不再包括补充参考信号资源集合指示序列。
该发射节点将该补充参考信号资源集合配置信息和PRS配置信息发送给定位服务器，定位服务器将所述信息发送给接收节点。接收节点根据所述信息配置检测时间窗和检测周期，在PRS信号被静音的周期内检测补充参考信号以完成定位。接收节点配置检测时间窗能够覆盖补充参考信号资源集合和PRS资源集合，根据补充参考信号和各个发射节点的PRS信号互相到达时间差进行定位。
