一种上行到达时间差定位方法及其装置
相关申请的交叉引用
本申请要求在2018年10月12日提交中国专利局、申请号为201811191693.1、申请名称为“一种上行到达时间差定位方法及其装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，尤其涉及一种上行到达时间差定位方法及其装置。
背景技术
上行到达时间差(uplink time difference of arrival，UTDOA)是一种3GPP协议规范所定义的定位方法。UTDOA定位的基本原理是：基站(base station)为终端(user equipment，UE)配置发送用于定位的探测参考信号(sounding reference signal，SRS)的资源；终端根据该SRS的配置发送SRS；定位服务器安排多个位置测量单元(location measurement units，LMU)同时测量SRS到达LMU的上行到达时间与LMU自身时间之差，称为上行到达时间时间差(UL relative time of arrival，UL RTOA)。UE发送的SRS到达各LMU所需的时间与UE和各LMU之间的传输路径的长度成比例。随后，各LMU将UL RTOA测量值报告给网络中的定位服务器。最后，定位服务器根据各LMU所报告的UL RTOA测量值估算出UE的位置。
在UTDOA定位过程中，在基站、LMU和定位服务器之间需要相互交换UTDOA信息，例如SRS配置信息、UL RTOA测量值等。其中，LMU根据SRS配置信息对UE发送的SRS进行测量得到UL RTOA测量值。
目前，UE定位所依据的信息有限，UE的定位性能或精度有待提高。

具体实施方式
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。

(2)本申请实施例中术语“多个”是指两个或两个以上，其它量词与之类似。
(3)“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
本申请实施例提供了一种基于上、下行参考信号(比如包括下行链路参考信号(DL-RS)，上行链路参考信号(UL-RS)，SRS等)的波束信息来辅助UTDOA定位的方法及其装置，以提高UTDOA定位精度或性能。
其中，参考信号的波束信息，可以包括以下信息中的一种或多种组合：
参考信号的波束标识，参考信号的波束方向，参考信号的波束宽度，参考信号的波束强度等，还可以包括参考信号的发送时间等。
本申请实施例可应用于长期演进(long term evolution，LTE)系统，也可应用于5G系统及其演进系统。本申请实施例中涉及的网络设备包括定位服务器、服务器管理软件(LuManager，LUM)、基站等。其中，定位服务器在LTE系统中称为演进服务移动定位中心(evolved serving mobile location center，E-SMLC)，在下一代无线接入网(new generation radio access network，NG-RAN)中称为本地管理功能(location management function，LMF)实体。基站在LTE系统中称为eNodeB，在5G系统中称为gNodeB。
参见图1，为本申请实施例提供的UTDOA定位流程示意图。
该流程中，待进行定位的终端称为目标终端。在对目标终端进行定位之前，目标终端与服务基站已建立连接，即目标终端处于无线资源控制连接(Radio Resource Control CONNECTED，RRC_CONNECTED)状态。
在UTDOA定位流程中，网络侧设备对终端发送的参考信号进行检测，以实现对终端的定位。其中，用于终端定位的参考信号可包括SRS或其他参考信号。本申请实施例中，以SRS为例进行描述，本申请实施例对用于实现终端定位的参考信号的类型不作限制。
目标终端与服务基站建立连接后，可执行以下流程以实现定位：
S101：定位服务器向目标终端的服务基站发送UTDOA信息请求(UTDOA INFORATION REQUEST)消息。
其中，所述UTDOA信息请求消息主要可用于以下两方面：一方面，用于请求服务基站为目标终端配置SRS资源，以便目标终端可以周期性发送SRS以支持UTDOA定位；另一方面，请求服务基站将为目标终端配置的SRS的配置信息发送给定位服务器。
可选地，所述UTDOA信息请求消息可以携带LMU检测SRS使用的接收波束信息。
其中，可选地，所述接收波束信息可以包括以下信息中的一种或多种组合：SRS的接收波束方向，SRS的接收波束宽度，SRS的接收波束与SRS接收时间之间的关系。
其中，可选地，所述LMU为所述服务基站周围的LMU。
S102～S103：服务基站接收UTDOA信息请求消息，为目标终端配置定位参考信号(如SRS)资源，并通过无线资源控制(radio resource control，RRC)信令将定位参考信号(如SRS)的配置信息发送给目标终端。
可选地，如果服务基站接收到的UTDOA信息请求消息中携带有LMU检测SRS使用的接收波束信息，则服务基站可以根据该SRS的接收波束信息为目标终端配置SRS资源。
例如，服务基站可以根据SRS的接收波束方向配置目标终端的SRS发送波束方向，以使得SRS的发送波束方向与接收波束方向相匹配，从而可以提高SRS的接收性能，进而提高定位精度。
再例如，若服务基站根据UTDOA信息请求消息中携带的LMU检测SRS使用的接收波束信息，确定LMU以波束扫描方式接收SRS，则服务基站可在为目标终端配置SRS时，参考LMU接收SRS所用的波束信息，配置SRS的发送时间和波束方向，使得目标终端发送SRS的时间和波束方向与LMU接收SRS的时间和波束方向相匹配。
目标终端收到RRC信令后，可按照SRS的配置，周期性地发送SRS。若目标终端被配置为以波束扫描的方式发送SRS，则目标终端发送SRS的波束方向与发送SRS的时间相关。
S104：服务基站向定位服务器发送UTDOA信息响应(UTDOA INFORATION RESPONSE)消息。
其中，所述UTDOA信息响应消息携带SRS的配置信息以及目标终端相关的参考信号的波束信息。
其中，可选地，所述目标终端相关的参考信号的波束信息，可包括作为定位参考信号的SRS的发送波束信息。具体实施时，UTDOA信息响应消息携带的SRS的配置信息，除了包括协议规定的SRS配置信息之外，还可包括SRS的波束信息。
所述目标终端相关的参考信号的波束信息还可包括以下信息中的至少一种：
目标终端测量到的下行参考信号(DL-RS)的波束信息。DL-RS的波束信息可包括DL-RS的波束标识和波束方向等信息。
具体实施时，处于连接状态(RRC_CONNECTED状态)的终端周期性测量DL-RS。所测量的DL-RS可以是SSB(SS/PBCH block)的同步信号或者信道状态信息参考信号(channel state indication reference signals，CSI-RS)或其它下行参考信号。在测量过程中，终端不断地将测量结果报告给服务基站， 服务基站将终端报告的DL-RS波束信息通过UTDOA信息响应消息发送给定位服务器。
进一步地，定位服务器接收到UTDOA信息响应消息后，可以利用其中携带的DL-RS的波束信息，确定用于检测目标终端发送的SRS的LMU，即确定哪些LMU在目标终端附近，应该参与检测该目标终端发送的SRS，以及哪些LMU远离该目标终端，无法接收该目标终端发送的SRS，不必要参与检测该目标终端发送的SRS，从而可以避免让哪些远离该目标终端而无法接收该目标终端发送的SRS的LMU参与检测该终端发送的SRS，进而避免浪费系统资源。
例如，如图2所示，LMU1，LMU2，LMU3距离终端较近，应该参与检测该终端发送的SRS，而LMU4距离终端较远，不必要参与检测该终端发送的SRS。
服务基站测量到的该目标终端发送的上行参考信号(UL-RS)的波束信息。
UL-RS的波束信息可包括UL-RS的波束标识和波束方向等信息。
处于连接状态(RRC_CONNECTED状态)的终端在与服务基站的数据通信过程中，服务基站可以测量该终端发送的上行参考信号(UL-RS)。所测量的UL-RS可以包括解调参考信号(demodulation reference signal，DM-RS)或者信道估计参考信号。服务基站可以将测量的UL-RS波束信息通过UTDOA信息响应消息发送给定位服务器。
进一步地，定位服务器接收到UTDOA信息响应消息后，可以利用其中携带的UL-RS的波束信息，确定用于检测目标终端发送的SRS的LMU，即确定哪些LMU在该目标终端附近，应该参与检测该目标终端发送的SRS，以及哪些LMU远离该目标终端，无法接收该目标终端发送的SRS，不必要参与检测该目标终端发送的SRS，从而可以避免让哪些远离该目标终端而无法接收该目标终端发送的SRS的LMU参与检测该终端发送的SRS，进而避免浪费系统资源。
S105：定位服务器接收UTDOA信息响应消息，向LMU发送测量信息请 求(MEASUREMENT REQUEST)消息。
其中，测量信息请求消息主要用于以下两方面：一方面，将从服务基站获得的目标终端的SRS配置信息发送给LMU，另一方面，请求LMU测量该目标终端发送的SRS。
其中，所述测量信息请求消息携带协议规定的SRS配置信息，还可进一步携带SRS的发送波束信息以及辅助定位信息。其中，所述辅助定位信息可以包括目标终端相关的参考信号的波束信息，或者包括根据目标终端相关的参考信号的波束信息确定得到的SRS的发送波束与LMU使用的接收波束之间的相对信息。
其中，所述目标终端相关的参考信号的波束信息，可包括目标终端测量到的下行参考信号(DL-RS)的波束信息，和/或，服务基站测量到的该目标终端发送的上行参考信号(UL-RS)的波束信息。具体说明可参见S104。
在一些实施例中，定位服务器可以直接用从服务基站接收到的UTDOA信息响应消息携带的SRS配置信息中SRS的发送波束信息(比如波束方向、波束宽度、波束强度等有关的信息)，以及UTDOA信息响应消息携带的终端的DL-RS波束信息(比如波束方向、波束宽度、波束强度等)，作为辅助定位信息。
在另一些实施例中，定位服务器可以直接用从服务基站接收到的UTDOA信息响应消息携带的SRS配置信息中SRS的发送波束信息(比如波束方向、波束宽度、波束强度等有关的信息)，以及UTDOA信息响应消息携带的终端的UL-RS波束信息(比如波束方向、波束宽度、波束强度等)，作为辅助定位信息。
在另一些实施例中，定位服务器可以根据从服务基站接收到的UTDOA信息响应消息携带的SRS配置信息中SRS的发送波束信息(比如波束方向、波束宽度、波束强度等有关的信息)，以及UTDOA信息响应消息携带的终端的DL-RS波束信息(比如波束方向、波束宽度、波束强度等)，确定出SRS的发送波束与LMU使用的接收波束之间的相对信息(比如SRS的发送波束 方向相对于LMU使用的接收波束方向)，并将确定出的SRS的发送波束与LMU使用的接收波束之间的相对信息作为辅助定位信息。
在另一些实施例中，定位服务器可以根据从服务基站接收到的UTDOA信息响应消息携带的SRS配置信息中SRS的发送波束信息(比如波束方向、波束宽度、波束强度等有关的信息)，以及UTDOA信息响应消息携带的终端的UL-RS波束信息(比如波束方向、波束宽度、波束强度等)，确定出SRS的发送波束与LMU使用的接收波束之间的相对信息(比如SRS的发送波束方向相对于LMU使用的接收波束方向)，并将确定出的SRS的发送波束与LMU使用的接收波束之间的相对信息作为辅助定位信息。
S106：LMU根据UTDOA信息响应消息携带的信息，对目标终端发送的定位参考信号(如SRS)进行测量，得到目标终端的定位测量信息。
可选地，若LMU接收到的测量信息请求消息中携带的辅助信息包括SRS的发送波束信息以及包括DL-RS波束信息或UL-RS波束信息，则LMU可基于服务基站或目标终端的大概位置，确定LMU与服务基站之间或LMU与目标终端之间的相对位置，并根据SRS的发送波束信息以及根据DL-RS波束信息或UL-RS波束信息，确定出SRS的发送波束与LMU使用的接收波束之间的相对信息(例如SRS的波束方向相对LMU的波束方向等)，并根据该信息对目标终端发送的SRS进行测量。
可选地，若LMU接收到的测量信息请求消息中携带的辅助信息为SRS的发送波束与LMU使用的接收波束之间的相对信息，则可以根据该信息对目标终端发送的SRS进行测量。
可选地，LMU可根据测量信息请求消息中携带的SRS发送波束信息，确定该LMU对该SRS的接收波束信息，以接收该目标终端发送的SRS。例如，如图3所示，若目标终端以波束扫描方式发送SRS，则LMU可以根据测量信息请求消息中携带的SRS发送波束信息确定SRS的波束发送方向和发送时间的关系，并可以利用这些信息来确定SRS的接收波束方向，以减少LMU搜索SRS所需要的时间和功耗，并提高检测SRS可靠性和UL RTOA测量精度。
S107：LMU向定位服务器发送测量信息响应(MEASUREMENT RESPONSE)消息，所述测量信息响应消息携带目标终端的定位测量信息以及测量到的定位参考信号(如SRS)的波束信息。
其中，测量信息响应消息可主要用于将测量的上行UL RTOA测量值报告给定位服务器，以便定位服务器根据LMU发送的UL RTOA测量值对该目标终端进行定位。
所述测量信息响应消息中除了协议规定的信息(如UL RTOA测量值)之外，可选地，该消息中还可携带其它与测量的SRS的波束有关的信息，比如，LMU所测到的SRS波束标识，和/或LMU所测到的SRS波束强度等。
S108：定位服务器接收测量信息响应消息，根据测量信息响应消息携带的定位测量信息，对目标终端进行定位。
可选地，该步骤中，定位服务器可以利用LMU检测到的SRS的波束方向、波束强度、SRS的到达时间差(UL RTOA)等信息来计算目标终端的位置，从而可以使得定位更可靠和更准确。
如图4所示，LMU1、LMU2和LMU3分别检测到来自UE的SRS波束x、波束y和波束z。UE位于SRS波束x、波束y和波束z的重叠区域。定位服务器可以在定位算法中，将LMU检测到的SRS的波束方向、波束强度与UL RTOA测量值结合在一起计算UE的位置，从而提高到达时间差定位法(Observed Time Difference of Arrival，OTDOA)的定位的准确性和可靠性。
需要说明的是，上述图1所示的流程中各步骤的时序关系没有严格要求，比如，S103和S104可以同时执行，也可以先执行S104再执行S103。
通过以上描述可以看出，本申请实施例可以基于上、下行参考信号(包括DL-RS，UL-RS和SRS)的波束信息(例如，波束ID、波束方向、波束宽度、波束强度等)来帮助提高UTDOA定位性能。
