需要说明的是,本申请中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被理解为比其他实施例或设计方案更有选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。

下面先给出本申请实施例可能出现的技术术语的说明。本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释,而非旨在限定本申请。应理解,下述各个技术术语的定义仅为举例。例如随着技术的不断发展,上述定义的范围也有可能发生变化,本申请各实施例不作限制。
(1)载波相位定位
载波相位定位技术是高精度定位的方法之一,其可以通过测量参考信号从发射端到接收端的载波相位变化实现测量带有整周模糊度的距离。以频率3GHz的射频信号为例,对应的载波波长为0.1米,因而当可以正确求解载波相位整周模糊度后,载波相位测距精度可以达到厘米级到毫米级,从而得到高精度定位结果。请参阅图1,图1是本申请实施例提供的一种载波相位测距的示意图。如图1所示,d表示接收端 与发射端之间的距离,表示载波相位测量值,N表示整周模糊度,N为整数,表示经过了N个载波整周,λ表示载波波长,距离d与载波相位之间满足:
(2)双差载波相位定位
请参阅图2,图2是本申请实施例提供的一种双差载波相位定位的示意图。如图2所示,版本R17中引入了参考站(positioning reference unit,PRU)辅助提升定位性能。具体地,可以利用已知位置的参考站对定位参考信号(positioning reference signal,PRS)进行测量,构建不同网络设备(如基站)之间的双差方程,消除非理想因素的影响,提升定位精度。也可以利用参考站进行双差载波相位定位。
双差载波相位的定位方法可以如下:
假设终端设备(如UE)和网络设备都存在同步/相位误差,终端设备测量的相位可表示为:
其中,表示终端设备与网络设备i之间的传输时延,表示终端设备与网络设备i的时间同步误差,φt和φ(i)分别表示终端设备与网络设备i的随机初相误差,表示终端设备与网络设备i之间的相位整周模糊度。
通过不同网络设备之间做差,得到到达相位差(phase difference of arrival,PDOA):
可以消除终端设备的随机初相φt。同样的对于PRU,可以测到PDOA:
终端设备与PRU之间再做差,可以得到双差PDOA:
可以消除网络设备侧的随机初相φ(i)以及时间同步误差Δ(ij),得到根据多个网络设备信息可以得到多个双差PDOA的测量值,联立方程组根据已知的PRU位置以及网络设备位置可计算得到待定位的终端设备位置。
首先,为了便于理解本申请实施例,进一步分析并提出本申请所具体要解决的技术问题。目前,关于双差载波相位定位的实现包括多种技术方案,以下示例性的列举如下几种,其中,如上所述,版本R17中引入了PRU辅助提升定位性能。然而在实际部署中,由于PRU与定位终端设备的相对位置关系会影响双差的定位性能,如果要进行双差载波相位定位来消除非理想因素的影响,需要在部署时尽可能的保证PRU的分布较密,因此需要的PRU的数量较多。PRU需要部署的数量较多,并且在复杂环境下存在PRU选点难以及PRU的维护成本较高等问题。
基于由于PRU部署导致双差载波相位定位的实现成本较高的问题,本申请实施例可以实现免信标的双差载波相位定位,从而降低双差载波相位定位的复杂度。
应理解,本申请实施例的技术方案可以应用于各种通信系统,例如:长期演进(long term evolution,LTE)系统、LTE频分双工(frequency division duplex,FDD)系统、LTE时分双工(time division duplex,TDD)系统、通用移动通信(universal mobile telecommunications system,UMTS)系统、增强型数据速率GSM演进(enhanced data rate for GSM evolution,EDGE)系统、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)系统。本申请实施例的技术方案还可以应用于其他通信系统,例如公共陆地移动网络(public land mobile network,PLMN)系统,高级的长期演进(LTE advanced,LTE-A)系统、第五代移动通信(the 5th generation,5G)系统、新空口(new radio,NR)系统、开放接入网(open RAN,ORAN)系统、机器与机器通信(machine to machine,M2M)系统、或者未来演进的其它通信系统等,本申请实施例对此不作限定。本申请实施例提供的技术方案还可以应用于其它的通信系统,只要该通信系统中存在实体可以发送控制信息,和发送(和/或接收)传输块,该通信系统中存在其它实体可以接收控制信息,和接收(和/或发送)传输块。

下面结合上述步骤S601-S609进行举例说明。请参阅图8,图8是本申请实施例提供的一种定位信息的上报方法的场景示意图。如图8所示,该场景可以包括多个网络设备(例如4个pRRU,分别为pRRU1~pRRU4),假设pRRU分别都有四个通道,其中pRRU1的一个通道用来发参考信号,其余三个通道 用来收参考信号,另外三个pRRU的四个通道都用来收参考信号,其中,pRRU1的架构可以支持环回收发。其中,pRRU可以在预留资源上接收来自自己或其它pRRU的参考信号。第一网络设备可以是多个pRRU中的任一pRRU。
示例性地,请参阅图9,图9是本申请实施例提供的一种在预留资源上接收参考信号的示意图。如图9所示,假设上下行时隙配比为2:8,多个网络设备间收发信号在自包含时隙(self-contained slot)内的GAP符号上,为了保证上下行切换,pRRU1发送参考信号与终端设备发送第二参考信号(如SRS)所占用的符号要有间隔,同时考虑到双差需要pRRU1发送参考信号与终端设备发送SRS之间的间隔尽可能的小,以消除对时间要求高的非理想因素的影响,因此pRRU间收发信号的位置可以如图9所示:pRRU1的第一个通道发送参考信号,位置在S时隙内的第8个GAP符号上,pRRU1的其余三个通道以及其它三个pRRU的四个通道可以在这个符号上接收pRRU1发送的参考信号(如SRS、PRS、RIM-RS等参考信号)。需要说明的是,多个pRRU之间可以轮发,即发送参考信号的pRRU可以是pRRU1~pRRU4轮询发,然后通过平均或滤波等方式提高相位校准量的精度。
pRRU1的位置已知并且向四个pRRU发送参考信号,这时可以将pRRU1当做一个信标。另外终端设备向四个pRRU发送SRS,可以形成双差定位。每个pRRU都可以将测到的来自终端设备的信号的相位信息与来自pRRU1的参考信号的第一信息上报给定位管理网元(如LMF网元),以使LMF网元可以做双差载波相位定位。
