定位是移动通信系统中的重要功能,要求系统能够实时地提供用户的位置信息。第五代(5thgeneration,5G)通信系统对定位提出了高精度的定位需求,要求室外的定位误差小于10米,室内的定位误差小于1米。
现有定位技术主要包括上行定位、下行定位和上下行定位。其中,上行定位中由基站对用户设备(user equipment,UE)发送的探测参考信号(sounding reference signal,SRS)进行测量,下行定位中由UE对基站发送的定位参考信号(positioning reference signal,PRS)进行测量,上下行定位中则既要求UE对基站发送的PRS进行测量,又要求基站对UE发送的SRS进行测量。

为便于理解本申请实施例,首先结合图1详细说明本申请实施例应用的通信系统的示意图。
如图1所示,该通信系统包括终端设备(图1中表示为UE)、无线接入网(图1中表示为下一代无线接入网(next generation radio access network,NG-RAN))与核心网。
无线接入网包括一个或多个下一代演进型节点B(next generation evolved node B,ng-eNB)和gNB。Ng-eNB表示接入5G核心网的LTE基站,gNB表示接入5G核心网的5G基站。Ng-eNB与gNB之间、或两个ng-eNB之间,或两个gNB之间通过Xn接口通信。Xn接口还可以称为XnAP接口。
无线接入网通过NG-C接口连接到核心网。
核心网包括接入和移动性管理功能(access and mobility management function,AMF)与定位管理功能(location management function,LMF)等其他功能。
LMF负责支持有关UE的不同类型的位置服务,包括对UE的定位和向UE传输辅助数据,LMF的控制面和用户面分别是增强服务移动定位中心(enhance-serving mobile location center,E-SMLC)和安全用户平面定位平台(secure user plane locator platform,SLP)。LMF可能与RAN,例如,ng-eNB或gNB,以及UE进行信号交互。例如,LMF与ng-eNB或gNB之间通过新空口定位协议副本(new radio positioning protocol annex,NRPPa)消息进行信息交互,例如,获取定位参考信号(position reference signal,PRS)、探测参考信号(sounding reference signal,SRS)的配置信息、小区定时、小区位置信息等。又例如,LMF与UE之间通过LTE定位协议(LTE positioning protocol,LPP)消息进行UE能力信息传递、辅助信息传递、测量信息传递等。
AMF实体可以从5G核心网(5G core,5GC)的位置服务(location service,LCS)实体接收与UE相关的位置服务请求,或者,AMF本身也可以代表特定UE启动一些位置服务,并将位置服务请求转发给LMF。
终端设备通过LTE-Uu接口经由ng-eNB连接到无线接入网。终端设备还可通过NR-Uu接口经由gNB连接到无线接入网。
应理解,该通信系统中可以包括一个或多个基站(包括ng-eNB或gNB)。
还应理解,该通信系统中可以包括一个或多个终端设备,例如包括一个或多个终端设备组(如图1中所示的UE set)。
一个gNB可以向一个或多个终端设备发送数据或控制信令。多个gNB也可以同时向一个终端设备发送数据或控制信令。
图1中的ng-eNB也可以替换为TP。
定位是移动通信系统中的重要功能,要求系统能够实时地提供用户的位置信息。5G通信系统对定位提出了高精度的定位需求,要求室外的定位误差小于10米,室内的定位误差小于1米。
现有的定位技术主要包括上行定位、下行定位和上下行定位。其中,上行定位中由基站对UE发送的SRS信号进行测量,下行定位中由UE对基站发送的PRS信号进行测量,上下行定位中则既要求UE对基站发送的PRS信号进行测量,又要求基站对UE发送的SRS信号进行测量。
实际定位中,由于不同UE和/或基站之间具有同步误差或相位误差,导致不同UE和/或基站对时延或相位的估计出现误差,进而带来定位误差,不能满足5G通信系统对定位精度的要求。
有鉴于此,本申请实施例提供一种定位的方法,通过引入参考设备辅助定位,从而消除由于不同UE和/或基站之间的同步误差或相位误差引起的定位误差,提高定位精度。
为便于理解本申请实施例,首先结合图2对到达时间差(time difference of arrival,TDOA)定位技术进行描述。
TDOA的定位原理为,通过测量无线电信号到达不同监测站的时间差,来对发射无线电信号的发射源进行定位。具体地,定位管理设备计算无线电信号到达两个监测站的时间差,根据该时间差获得距离差,从而得到一条双曲线;定位管理设备通过三个或多个监测站测得的时间差可以得到两条或多条双曲线,进而,定位管理设备根据该两条或多条双曲线的相交点来实现对发射源的定位。
图2为TDOA定位技术的示意图。图2中的终端设备对应于上述TDOA定位技术中发射无线电信号的发射源,图2中的基站1、基站2和基站3对应于上述TDOA定位技术中测量无线电信号的监测站。即终端设备发送信号,基站1、基站2和基站3分别测量终端设备发送的信号。
作为示例,终端设备发送的信号到达基站1和基站2的时间差为Δt1,终端设备发送的信号到达基站2和基站3的时间差为Δt2。将时间差Δt1乘以电磁波速度获得距离差L1,将时间差Δt2乘以电磁波速度获得距离差L2。定位管理设备根据基站1的位置、基站2的位置以及距离差L1之间的函数关系,得到图2中所示的双曲线MN,定位管理设备根据基站2的位置、基站3的位置以及距离差L2之间的函数关系,得到图2中所示的双曲线RS。进而,定位管理设备根据双曲线MN与双曲线RS的相交点,可以实现终端设备的定位。
在图2中,基站1、基站2与基站3中的一个基站为终端设备的服务基站,其余两个基站为终端设备的邻区基站。
终端设备的服务基站是指当前为终端设备提供通信连接服务的基站。终端设备的邻区基站是指与服务基站相邻的基站。换句话说,服务基站是指终端设备的服务小区的基站。邻区基站指的是终端设备的服务小区的相邻小区的基站。
需要说明的是,在图2中,采用3个基站实现对终端设备的定位,但本申请对此不作 限定,实际应用中,还可以采用3个以上的基站实现对终端设备的定位。
下面结合图3和图4说明本申请实施例提供的定位方法。
图3示出本申请实施例提供的定位方法的示意性流程图。下面详细描述方法300包括的各个步骤。

第一测量TDOA是待定位终端设备发送的信号(例如SRS信号)到达第一定位测量设备和第二定位测量设备的时间差,即第一测量TDOA是第一相对到达时间(relative time of arrival,RTOA)与第二RTOA的差值。第一RTOA是第一定位测量设备通过测量来自待定位终端设备的信号得到的,第二RTOA是第二定位测量设备通过测量来自待定位终端设备的信号得到的。

第二RTOA可以表示为:其中,表示第二RTOA,表示UE发送的SRS信号在UE与BS2之间传输的理论时长,eBS2表示BS2相对于基准时间T的时钟偏移或相位偏移所引入的误差。可以理解,在实际测量中,BS2和/或UE与基准时间T不可能完全同步,因此和/或eUE不为0。
将第二RTOA与第一RTOA相减得到的第一测量TDOA可以表示为: 表示第一测量TDOA。当然,第一测量TDOA也可以是第一RTOA与第二RTOA相减得到的,本申请对此不做限定。
第二测量TDOA是参考设备发送的信号(例如SRS信号)到达第一定位测量设备和第二定位测量设备的时间差,即第二测量TDOA是第三RTOA与第四RTOA的差值。第三RTOA是第一定位测量设备通过测量来自参考设备的信号得到的,第四RTOA是第二定位测量设备通过测量来自参考设备的信号得到的。其中,参考设备与定位测量设备之间的实际距离已知,或者,参考设备与定位测量设备之间的实际距离可以通过激光测距或红外测距得到,或者,参考设备与定位测量设备之间的实际距离可以根据参考设备与定位测量设备的实际位置计算得到。或者,参考设备的实际位置已知,或者,参考设备的实际位置可以通过全球导航卫星系统(global navigation satellite system,GNSS)、WiFi、蓝牙等对参考设备进行定位得到。
参考图4,图4中的UE_r是参考设备,第三RTOA可以表示为: 其中,表示第三RTOA,表示UE_r发送的SRS信号在UE_r与BS1之间传输的理论时长,eUE_r表示UE_r相对于基准时间T的时钟偏移或相位偏移所引入的误差。可以理解,在实际测量中,BS1和/或UE_r与基准时间T不可能完全同步,因此eBS1和/或eUE_r不为0。
第四RTOA可以表示为:其中,表示第二RTOA,表示UE_r发送的SRS信号在UE_r与BS2之间传输的理论时长。可以理解,在实际测量中,BS2和/或UE_r与基准时间T不可能完全同步,因此eBS2和/或eUE_r不为0。
将第四RTOA与第三RTOA相减得到的第二测量TDOA可以表示为: 表示第二测量TDOA。当然,第二测量TDOA也可以是第三RTOA与第四RTOA相减得到的,本申请对此不做限定。
示例性地,定位管理设备接收定位信息包括:定位管理设备接收来自第一定位测量设备的第一RTOA和第三RTOA;定位管理设备接收来自第二定位测量设备的第二RTOA和第四RTOA。
又示例性地,定位管理设备接收定位信息包括:定位管理设备接收来自第一定位测量设备的第一RTOA、第二RTOA、第三RTOA和第四RTOA。其中,第二RTOA和第四RTOA第二定位测量设备向第一定位测量设备发送的。
或者,定位管理设备接收来自第一定位测量设备的第一TDOA和第二TDOA,即第一定位测量设备接收到来自第二定位测量设备的第二RTOA和第四RTOA之后,根据第一RTOA和第二RTOA得到第一TDOA,再根据第三RTOA和第四RTOA得到第二TDOA,并将第一TDOA和第二TDOA发送给定位管理设备。
再示例性地,定位管理设备接收定位信息包括:定位管理设备接收来自第二定位测量设备的第一RTOA、第二RTOA、第三RTOA和第四RTOA。其中,第一RTOA和第三RTOA第一定位测量设备向第二定位测量设备发送的。

如上所述,当采用TDOA定位技术对待定位终端设备进行定位时,待定位终端设备的位置是根据至少两条双曲线的交点得到的,而至少两条双曲线是根据至少两个TDOA得到的。因此,为了对待定位终端设备定位,定位信息还可以用于确定第三测量TDOA和第四测量TDOA。第三测量TDOA是待定位终端设备发送的信号到达第三定位测量设备和第四定位测量设备的时间差,关于第三测量TDOA的更多描述可以参考第一测量TDOA。第四测量TDOA是参考设备发送的信号到达第三定位测量设备和第四定位测量设备的时间差,关于第四测量TDOA的更多描述可以参考第二测量TDOA。第一定位测量设备、第二定位测量设备、第三定位测量设备和第四定位测量设备中包括至少三个不同的定位测量设备。

第一理论TDOA是参考设备发送的信号到达第一定位测量设备和第二定位测量设备的理论时间差。
第二理论TDOA是待定位终端设备发送的信号到达第一定位测量设备和第二定位测量设备的理论时间差。
示例性地,若第一测量TDOA与第二测量TDOA的差值是由第一测量TDOA减去第二测量TDOA得到的,则第二理论TDOA等于第一测量TDOA与第二测量TDOA的差值与第一理论TDOA的和。

又示例性地,若第一测量TDOA与第二测量TDOA的差值是由第二测量TDOA减去第一测量TDOA得到的,则第二理论TDOA等于第一理论TDOA减去第一测量TDOA与第二测量TDOA的差值得到的差。
将上述第二测量TDOA(即)与第一测量TDOA相减得到的差值的过程表示为:已知的情况下,定位管理设备根据可以得到第二理论TDOA,即

例如,上述第三测量TDOA(即)与第四测量TDOA相减得到的差值的过程表示为:其中表示第三理论TDOA, 表示UE_r与BS3之间的实际距离。在已知参考设备的位置或参考设备与定位测量设备(包括第三定位测量设备和第四定位测量设备)之间的实际距离的情况下,相当于是已知的。进而,定位管理设备根据可以得到第四理论TDOA,即
S330,定位管理设备根据第二理论TDOA对待定位终端设备定位。
定位管理设备根据第二理论TDOA对待定位终端设备定位的方法包括:定位管理设 备根据第二理论TDOA和电磁波速度获得距离差L1;进而根据第一定位测量设备的位置、第二定位测量设备的位置以及距离差L1之间的函数关系,得到一条双曲线(例如图4所示的双曲线1)。
可以理解,定位管理设备还根据上述第四理论TDOA对待定位终端设备定位,即定位管理设备根据第四理论TDOA和电磁波速度获得距离差L2;进而根据第三定位测量设备的位置、第四定位测量设备的位置以及距离差L2之间的函数关系,得到另一条双曲线(例如图4所示的双曲线2)。双曲线1与双曲线2的交点是待定位终端设备所在的位置。
在本申请实施例中,在引入参考设备的情况下,通过将测量参考设备发送的信号得到的测量TDOA与测量待定位终端设备发送的信号得到的测量TDOA相减,可以消除定位测量设备的时钟偏移或相位偏移引入的误差,得到待定位终端设备与定位测量设备之间的理论TDOA。当定位管理设备根据待定位终端设备与定位测量设备之间的理论TDOA对待定位终端设备定位时,可以确定更精确的待定位终端设备的位置。
然而,在实际测量中,定位测量设备测量来自待定位终端设备的信号时,在时域上测量的相位存在相位漂移。以上述第一定位测量设备测量来自待定位终端设备的信号为例,若第一定位测量设备在时域上测量的相位存在相位漂移,则上述第一RTOA可以表示为:t1表示第一定位测量设备在时域上测量的相位存在相位漂移所引入的误差。由于不同定位测量设备在时域上测量的相位存在的相位漂移不同,因此即使采用图3所述的定位方法,也无法消除定位测量过程中由于相位漂移产生的误差。
有鉴于此,本申请实施例还提供一种定位方法,以期消除或减小定位测量过程中由于相位漂移引入的误差,从而提高定位精度。
图5示出了本申请另一实施例提供的定位方法的示意性流程图。下面详细描述方法500包括的各个步骤。
S510,网络设备#1接收来自第一参考终端设备的第一SRS信号。
示例性的,网络设备#1是待定位终端设备的服务网络设备,待定位终端设备是位置未知的终端设备。又示例性的,网络设备#1是与待定位终端设备的服务网络设备相邻的网络设备。再示例性的,网络设备#1是第一参考终端设备的服务网络设备。其中,第一参考终端设备是具备发送SRS信号的能力的设备。第一参考终端设备与网络设备(包括网络设备#1)之间的实际距离已知,或者,第一参考终端设备与网络设备之间的实际距离可以通过激光测距或红外测距得到,或者,第一参考终端设备与网络设备之间的实际距离可以根据第一参考终端设备与网络设备的实际位置计算得到。第一参考终端设备的实际位置已知,或者,第一参考终端设备的实际位置可以通过GNSS、WiFi、蓝牙等对第一参考终端设备进行定位得到。
具体地,网络设备#1在第一SRS资源上接收来自第一参考终端设备的第一SRS信号。相应地,第一参考终端设备在第一SRS资源上发送第一SRS信号。
可选的,若网络设备#1不是第一参考终端设备的服务网络设备,则网络设备#1在接收第一SRS信号前,方法500还包括:网络设备#1接收来自定位管理设备的第一SRS资源的信息,第一SRS资源的信息用于确定第一SRS资源。相应的,网络设备#1根据第一SRS资源的信息确定第一SRS资源,并在第一SRS资源上接收第一SRS信号。
示例性的,第一SRS资源的信息包括第一SRS资源的资源配置信息和/或第一SRS资 源的标识(identifier,ID)。第一SRS资源的资源配置信息包括以下一项或多项:起始符号位置,占用符号数,发送周期和偏移,传输梳齿及偏移,循环移位,频域位置和偏移,跳频配置。第一SRS资源的ID用于标识第一SRS资源,第一SRS资源的ID也可以称为第一SRS资源的编号。
S520,网络设备#1接收来自待定位终端设备的第二SRS信号。
具体地,网络设备#1在第二SRS资源上接收来自待定位终端设备的第二SRS信号。相应地,待定位终端设备在第二SRS资源上发送第二SRS信号。
一种可能的实现方式中,第一SRS资源与第二SRS资源之间存在至少一个重叠的时域单元。时域单元可以是帧(frame)、子帧(subframe)、时隙(slot)、符号(symbol)、毫秒(ms)等。
例如,第一SRS资源与第二SRS资源之间存在至少一个重叠的时域单元包括以下几种情况:第一SRS资源与第二SRS资源之间没有时域单元的偏移,第一SRS资源与第二SRS资源之间存在一个时域单元的偏移。
第一SRS资源与第二SRS资源之间没有时域单元的偏移指的是,第一SRS资源的起始符号位置与第二SRS资源的起始符号位置相同,和/或,第一SRS资源的结束符号位置与第二SRS资源的结束符号位置相同。图6示出了第一SRS资源与第二SRS资源之间没有时域单元的偏移的示例。如图6中的(a)所示,第一SRS资源与第二SRS资源在时域上都占用了符号11至符号14,即第一SRS资源的起始符号位置与第二SRS资源的起始符号位置相同,且,第一SRS资源的结束符号位置与第二SRS资源的结束符号位置相同。如图6中的(b)所示,第一SRS资源占用了符号11和符号12,第二SRS资源占用了符号11至符号14,即第一SRS资源的起始符号位置与第二SRS资源的起始符号位置相同。如图6中的(c)所示,第一SRS资源占用了符号11至符号14,第二SRS资源占用了符号13和符号14,即第一SRS资源的结束符号位置与第二SRS资源的结束符号位置相同。
如图6中的(a)所示,在第一SRS资源的时域位置与第二SRS资源的时域位置完全相同的情况下,也可以说第一SRS资源与第二SRS资源在时域上完全重叠。如图6中的(b)或(c)所示,在第一SRS资源的时域位置与第二SRS资源的时域位置部分相同的情况下,也可以说第一SRS资源与第二SRS资源在时域上部分重叠。
在第一SRS资源与第二SRS资源存在一个时域单元的偏移的情况下,该偏移指的是第一SRS资源的第n个时域单元与第二SRS资源的第n个时域单元之间的偏移。例如,该偏移指的是第一SRS资源的起始符号位置与第二SRS资源的起始符号位置之间的偏移,或者,指的是第一SRS资源的结束符号位置与第二SRS资源的结束符号位置之间的偏移。图7示出了第一SRS资源与第二SRS资源之间存在一个时域单元的偏移的示例。如图7中的(a)所示,第一SRS资源占用了符号12和13,第二SRS资源占用了符号11至符号14,即第一SRS资源的起始符号位置与第二SRS资源的起始符号位置存在一个符号的偏移,第一SRS资源的结束符号位置与第二SRS资源的结束符号位置也存在一个符号的偏移。如图7中的(b)所示,第一SRS资源占用了符号12至符号14,第二SRS资源占用了符号11和符号12,即第一SRS资源的起始符号位置与第二SRS资源的起始符号位置存在一个符号的偏移,第一SRS资源的第二个符号位置与第二SRS资源的第二个符号位置也存在一个符号的偏移。如图7中的(c)所示,第一SRS资源占用了符号11至符号 13,第二SRS资源占用了符号13和符号14,即第一SRS资源的结束符号位置与第二SRS资源的结束符号位置存在一个符号的偏移。
如图7中的(b)或(c)所示,当第一SRS资源与第二SRS资源之间的时域单元的偏移的定义不同时,第一SRS资源与第二SRS资源之间的偏移量也可能不同。如图7中的(b)所示,若第一SRS资源与第二SRS资源之间的时域单元的偏移指的是结束符号位置之间的偏移,则第一SRS资源与第二SRS资源之间存在两个符号的偏移。如图7中的(c)所示,若第一SRS资源与第二SRS资源之间的偏移指的是起始符号位置之间的偏移,则第一SRS资源与第二SRS资源之间存在两个符号的偏移。
需要说明的是,本申请实施例不限定第一SRS资源与第二SRS资源之间存在一个时域单元的偏移。在第一SRS资源与第二SRS资源之间存在至少一个重叠的时域单元的情况下,第一SRS资源与第二SRS资源之间可以存在两个及两个以上的时域单元的偏移。
另一种可能的实现方式中,第二SRS资源与第一SRS资源在时域上相邻且间隔的时域单元数不超过预设值。
例如,若第二SRS资源的时域位置在第一SRS资源的时域位置之前,则第二SRS资源的结束符号位置与第一SRS资源的起始符号位置之间间隔的符号数不超过预设值。或者,若第一SRS资源的时域位置在第二SRS资源的时域位置之前,则第一SRS资源的结束符号位置与第二SRS资源的起始符号位置之间间隔的符号数不超过预设值。如图8中的(a)所示,第一SRS资源占用符号10和符号11,第二SRS资源占用符号13和14,第一SRS资源的结束符号位置(即符号11)与第二SRS资源的起始符号位置(即符号13)间隔一个符号,则第一SRS资源与第二SRS资源在时域上间隔一个符号。又例如,第二SRS资源与第一SRS资源占用的时域单元交叉排列,则第二SRS资源的任意一个符号与相邻的由第一SRS资源占用的符号之间间隔的符号数不超过预设值。如图8中的(b)所示,第二SRS资源占用的符号11与第一SRS资源占用的符号10和符号12相邻且间隔的符号数为0,则第一SRS资源与第二SRS资源间隔的符号数为0。
示例性的,时域单元是符号,预设值是1,即第二SRS资源与第一SRS资源在时域上最多间隔一个符号。
需要说明的是,本申请实施例不限定第一SRS资源与第二SRS资源在频域上的关系,第一SRS资源与第二SRS资源既可以在频域上重叠,也可以在频域上不重叠。如图6所示,第一SRS资源与第二SRS资源在频域上完全不重叠。又如图8所示,第一SRS资源与第二SRS资源在频域上重叠。
可选的,若网络设备#1不是待定位终端设备的服务网络设备,则网络设备#1在接收第二SRS信号前,方法500还包括:网络设备#1接收来自定位管理设备的第二SRS资源的信息,第二SRS资源的信息用于确定第二SRS资源。相应的,网络设备#1根据第二SRS资源的信息确定第二SRS资源,并在第二SRS资源上接收第二SRS信号。
示例性的,第二SRS资源的信息包括第二SRS资源的资源配置信息和/或第二SRS资源的ID。第二SRS资源的信息的更多描述可以参考上文第一SRS资源的信息的描述。
可选地,在S510和S520之前,方法500还包括:网络设备#1接收来自定位管理设备的测量请求(measurement request)消息。测量请求消息用于请求网络设备#1测量来自待定位终端设备的第二SRS信号,以及测量来自第一参考终端设备的第一SRS信号。示 例性的,定位管理设备通过NRPPa协议向网络设备#1发送测量请求消息,即定位管理设备向网络设备#1发送NRPPa测量请求消息。
S530,网络设备#1向定位管理设备发送定位信息。相应地,定位管理设备接收来自网络设备#1的定位信息。
其中,定位信息是网络设备#1通过测量第一SRS信号和第二SRS信号得到的,定位信息用于对待定位终端设备定位。示例性地,定位信息包括RTOA#1和RTOA#2,RTOA#1是第一SRS信号到达网络设备#1的相对到达时间,RTOA#2是第二SRS信号到达网络设备#1的相对到达时间。又示例性地,定位信息包括AOA#1和AOA#2,AOA#1是第一SRS信号到达网络设备#1的到达角,AOA#2是第二SRS信号到达网络设备#1的到达角。再示例性地,定位信息包括RTOA#1、RTOA#2、AOA#1和AOA#2。可选地,定位信息还包括网络设备#1测量第一SRS信号得到的参考信号接收功率(reference signal receiving power,RSRP)#1和服务网络设备#1测量第二SRS信号得到的RSRP#2。
可选的,网络设备#1向定位管理设备发送定位信息,包括:网络设备#1向定位管理设备发送测量响应消息,测量响应消息包括定位信息。示例性的,网络设备#1通过NRPPa协议向定位管理设备发送测量响应(measurement response)消息,即网络设备#1向定位管理设备发送NRPPa测量响应消息。
可选地,方法500还包括:网络设备#1接收来自定位管理设备的定位去激活(positioning deactivation)消息。进而,网络设备#1不再测量第一SRS信号和第二SRS信号。示例性的,定位管理设备通过NRPPa协议向网络设备#1发送定位去激活消息,即定位管理设备向网络设备#1发送NRPPa定位去激活消息。
S540,定位管理设备根据定位信息对待定位终端设备定位。
定位管理设备接收到定位信息之后,可以根据定位信息对待定位终端设备定位。可以理解,若定位信息包括RTOA#1和RTOA#2,则定位管理设备可以通过TDOA定位技术对待定位终端设备定位。若定位信息包括AOA#1和AOA#2,则定位管理设备可以通过AOA定位技术对待定位终端设备定位。
下面以定位管理设备通过图3所述的方法对待定位终端设备定位为例,说明图5所述的方法可以消除或减小相位漂移引入的误差的原理。
应理解,当定位管理设备通过TDOA定位技术对待定位终端设备定位时,定位管理设备需要根据至少三个网络设备(包括上述网络设备#1)测量第一SRS信号和第二SRS信号得到的测量结果对待定位终端设备定位。参考图4,假设至少三个网络设备包括BS1(即网络设备#1)、BS2和BS3。BS2测量第一SRS信号和第二SRS信号得到的测量结果包括RTOA#3和RTOA#4,RTOA#3是第一SRS信号到达BS2的相对到达时间,RTOA#4是第二SRS信号到达BS2的相对到达时间。BS3测量第一SRS信号和第二SRS信号得到的测量结果包括RTOA#5和RTOA#6,RTOA#5是第一SRS信号到达BS3的相对到达时间,RTOA#6是第二SRS信号到达BS3的相对到达时间。
RTOA#1可以表示为:其中,表示UE_r(即第一参考终端设备)发送的第一SRS信号在UE_r与BS1之间传输的理论时长,eBS1表示BS1相对于基准时间T的时钟偏移或相位偏移所引入的误差,eUE_r表示UE_r相对于基准时间T的时钟偏移或相位偏移所引入的误差,t1表示表示BS1在第一SRS资源的时域上 测量的相位存在相位漂移所引入的误差。
RTOA#2可以表示为:其中,表示UE(即待定位终端设备)发送的第二SRS信号在UE与BS1之间传输的理论时长,eUE表示UE相对于基准时间T的时钟偏移或相位偏移所引入的误差,t2表示表示BS1在第二SRS资源的时域上的测量的相位存在相位漂移所引入的误差。
RTOA#3可以表示为:其中,表示UE_r发送的第一SRS信号在UE_r与BS2之间传输的理论时长,eBS2表示BS1相对于基准时间T的时钟偏移或相位偏移所引入的误差,t3表示表示BS2在第一SRS资源的时域上测量的相位存在相位漂移所引入的误差。
RTOA#4可以表示为:其中,表示UE发送的第二SRS信号在UE与BS2之间传输的理论时长,t4表示表示BS2在第二SRS资源的时域上测量的相位存在相位漂移所引入的误差。
RTOA#5可以表示为:其中,表示UE_r发送的第一SRS信号在UE_r与BS3之间传输的理论时长,eBS3表示BS3相对于基准时间T的时钟偏移或相位偏移所引入的误差,t5表示表示BS3在第一SRS资源的时域上测量的相位存在相位漂移所引入的误差。
RTOA#6可以表示为:其中,表示UE发送的第二SRS信号在UE与BS3之间传输的理论时长,t6表示表示BS3在第二SRS资源的时域上测量的相位存在相位漂移所引入的误差。
进一步地,定位管理设备对RTOA#3和RTOA#1作差得到TDOA#1,即对RTOA#4和RTOA#2作差得到TDOA#2,即定位管理设备再对TDOA#2和TDOA#1作差得到:在已知UE_r的位置或UE_r与网络设备(包括BS1和BS2)之间的实际距离的情况下,相当于是已知的。进而,定位管理设备可以得到进而,定位管理设备可以根据和电磁波速度获得距离差L1,并根据BS1的位置、BS2的位置以及距离差L1之间的函数关系,得到一条双曲线(例如图4所示的双曲线1)。
定位管理设备对RTOA#5和RTOA#1作差得到TDOA#3,即对RTOA#6和RTOA#2作差得到TDOA#4,即定位管理设备再对TDOA#4和TDOA#3作差得到:在已知UE_r的位置或UE_r与网络设备(包括BS1和BS3)之间的实际距离的情况下,相当于是已知的。进而,定位管理设备可以得到进而,定位管理设备可以根据和电磁波速度获得距离差L2,并根据BS1的位置、BS3的位置以及距离差L2之间的函数关系,得到一条双曲线(例如图4所示的双曲线2)。
进而,定位管理设备确定待定位终端设备位于双曲线1和双曲线2的交点。
应理解,若第一SRS资源与第二SRS资源在时域上完全重叠,则网络设备#1在第一 SRS资源和第二SRS资源的时域上测量的相位存在的相位漂移是相同的,因此t2与t1相等。类似地,t3与t4相等,t5与t6相等。基于此,在上述定位的流程中,定位管理设备通过对TDOA#1和TDOA#2作差可以得到以及通过对TDOA#3和TDOA#4作差可以得到进而,定位管理设备根据对待定位终端设备进行定位时,可以得到更精确的待定位终端设备的位置。也就是说,若第一SRS资源与第二SRS资源在时域上完全重叠,定位管理设备通过对TDOA#1和TDOA#2、TDOA#3和TDOA#4作差,不只可以消除网络设备的时钟偏移或相位偏移引入的误,还可以消除网络设备测量的相位存在相位漂移引入的误差。
若第一SRS资源与第二SRS资源在时域上部分重叠,或者第一SRS资源与第二SRS资源在时域上相邻且间隔时间单元数不超过预设值,则网络设备#1在第一SRS资源和第二SRS资源的时域上测量的相位存在的相位漂移比较接近,因此t2与t1的差值很小。类似地,t3与t4差值很小,t5与t6差值很小。基于此,在上述定位的流程中,定位管理设备通过对TDOA#2和TDOA#1、TDOA#4和TDOA#3作差,虽然不能完全消除网络设备测量的相位存在相位漂移引入的误差,但是与第一SRS资源与第二SRS资源之间的时域间隔很大的情况相比,可以在一定程度上减小由于相位漂移引入的误差。
在本申请实施例中,待定位终端设备在第一SRS资源上发送第一SRS信号,第一参考终端设备在第二SRS资源上发送第二SRS信号,由于第一SRS资源与第二SRS资源之间存在至少一个重叠的时域单元,因此,当通过测量第一SRS信号和第二SRS信号对待定位终端设备定位时,同一个网络设备分别在第一SRS资源和第二SRS资源的时域上测量的相位存在的相位漂移相同或相近,从而有助于消除或减小相位漂移引入的误差,提高定位精度。
可以理解,在待定位终端设备通过第二SRS资源发送第二SRS信号之前,待定位终端设备的服务网络设备(下文中记为服务网络设备#1)为待定位终端设备配置第二SRS资源,以及在第一参考终端设备通过第一SRS资源发送第一SRS信号之前,第一参考终端设备的服务网络设备(下文中记为服务网络设备#2)为第一参考终端设备配置第一SRS资源。下面结合图9和图10说明为待定位终端设备和第一参考终端设备配置SRS资源的方法。
图9示出了本申请实施例提供的资源配置方法的示意性流程图。在图9所示的方法中,在待定位终端设备发送第二SRS信号之前,服务网络设备#1根据协议预定义的方式或者根据定位管理设备的指示,为待定位终端设备配置第二SRS资源。下面详细说明方法900包括的各个步骤。
需要说明的是,针对服务网络设备#1与服务网络设备#2是同一个网络设备、服务网络设备#1与服务网络设备#2是不同的网络设备这两种情况,为待定位终端设备和第一参考终端设备配置SRS资源的方式不同。下面分别说明上述两种情况下,为待定位终端设备和第一参考终端设备配置SRS资源的方法。
情况1,服务网络设备#1与服务网络设备#2是不同的网络设备,则为待定位终端设备和第一参考终端设备配置SRS资源的方法包括如下步骤。
S910,服务网络设备#1接收来自定位管理设备的第一参考SRS资源信息。相应地,定位管理设备向服务网络设备#1发送第一参考SRS资源信息。
示例性的,第一参考SRS资源信息包括以下一项或多项:起始符号位置,占用符号数,发送周期和偏移,传输梳齿及偏移,循环移位,频域位置和偏移,跳频配置。

S920,服务网络设备#1向待定位终端设备发送第二SRS资源的资源配置信息。
第二SRS资源的资源配置信息指示第二SRS资源,第二SRS资源的资源配置信息包括以下一项或多项:起始符号位置,占用符号数,发送周期和偏移,传输梳齿及偏移,循环移位,频域位置和偏移,跳频配置。
服务网络设备#1接收到第一参考SRS资源信息之后,则根据第一参考SRS资源信息为待定位终端设备配置第二SRS资源。例如,服务网络设备#1接收到第一参考SRS资源信息之后,根据第一参考SRS资源信息确定第一SRS资源的时域位置,然后为待定位终端设备确定与第一SRS资源存在至少一个重叠的时域单元的第二SRS资源。示例性的,时间单元是符号。
例如,若第一参考SRS资源信息包括起始符号位置,则服务网络设备#1可以根据第一参考SRS资源信息为待定位终端设备配置占用该起始符号的第二SRS资源,从而有利于实现第一SRS资源与第二SRS资源之间至少存在一个重叠的时域单元。例如,第一参考SRS资源信息包括的起始符号位置是第一SRS资源的起始符号位置,则第一SRS资源和第二SRS资源在该起始符号位置上重叠。
又例如,若第一参考SRS资源信息包括起始符号位置和占用符号数,则服务网络设备#1可以根据第一参考SRS资源信息确定一个SRS资源的时域位置,进而服务网络设备#1可以为待定位终端设备确定与该SRS资源至少存在一个重叠的时域单元的第二SRS资源,从而有利于实现第一SRS资源与第二SRS资源之间至少存在一个重叠的时域单元。例如,若根据第一参考SRS资源信息确定的SRS资源包括第一SRS资源,服务网络设备#2为待定位终端设备配置的第二SRS资源与根据第一参考SRS资源信息确定的SRS资源完全重叠,则第一SRS资源和第二SRS资源之间存在至少一个重叠的符号。
再例如,若第一参考SRS资源信息包括频域位置和偏移,则服务网络设备#1可以根据第一参考SRS资源信息确定与该频域位置和偏移对应的SRS资源的时域位置,进而服务网络设备#1可以为待定位终端设备确定与该SRS资源至少存在一个重叠的时域单元的第二SRS资源,从而有利于实现第一SRS资源与第二SRS资源之间至少存在一个重叠的时域单元。
可选的,若在S910中,服务网络设备#1接收到多个参考SRS资源信息,则服务网络设备#1从多个参考SRS资源信息中选出第一参考SRS资源信息,再根据第一参考SRS资源信息为待定位终端设备配置第二SRS资源。示例性的,第一参考SRS资源信息是多个参考SRS资源信息中优先级最高的。又示例性的,第一参考SRS资源信息是至少一个目标参考SRS资源信息中优先级最高的,至少一个目标参考SRS资源信息属于多个参考SRS资源信息,且至少一个目标参考SRS资源信息中的每个目标参考SRS资源信息指示的SRS 资源与可分配给待定位终端设备的SRS资源之间存在至少一个重叠的时域单元。例如,多个参考SRS资源信息中的参考SRS资源信息#A指示的SRS资源#A占用符号11和符号12,多个参考SRS资源信息中的参考SRS资源信息#B指示的SRS资源#B占用符号13和符号14,可分配给待定位终端设备的SRS资源占用符号11和14,即SRS资源#A和SRS资源#B与可分配给待定位终端设备的SRS资源在时域上存在一个重叠的符号。进一步地,若参考SRS资源信息#A的优先级高于参考SRS资源信息#B的优先级,则服务网络设备#1将参考SRS资源信息#A确定为第一参考SRS资源信息。
