Definitions
- This application relates to the field of communication technology, and in particular to information transmission methods and devices.
- Step 1 After a user terminal (User Equipment, UE) establishes a connection with a base station, the UE is in a Radio Resource Control Connected (RRC_CONNECTED) state.
- RRC_CONNECTED Radio Resource Control Connected
- Step 2 The location server (Location Management Function, LMF) sends a "request location capability" message to the UE, requesting the UE to notify the LMF of the location function supported by the UE.

- Step 3 The UE sends a "Provide Positioning Capability" message in response to the LMF, and the "Provide Positioning Capability" message reports that the UE supports OTDOA positioning capabilities.
- Step 4 When the downlink positioning assistance data is needed, the UE sends a "request positioning assistance data" message to the LMF, which is used to request the LMF to provide OTDOA assistance data.
- Step 5 The LMF sends an "OTDOA Information Request" message to the base station, which is used to request the base station to provide downlink positioning assistance data, such as Down Link (DL) positioning reference signal (Positioning Reference Signal, PRS) configuration data.

本申请要求在2019年11月25日提交中国专利局、申请号为201911168857.3、申请名称为“信息传输方法及装置”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。
本申请涉及通信技术领域,尤其涉及信息传输方法及装置。
图1和图2以下行(Down Link,DL)观察到达时差(Observed Time Difference Of Arrival,OTDOA)定位为例,示出了目前方案中的常见的流程示意图,包括下面11个步骤:
步骤1、在用户终端(User Equipment,UE)建立与基站的连接之后,UE处于无线资源控制连接(Radio Resource Control Connected,RRC_CONNECTED)状态。
步骤2、定位服务器(Location Management Function,LMF)向UE发送“请求定位能力”消息,请求UE通知LMF该UE所能支持的定位功能。
步骤3、UE发送“提供定位能力”消息来响应LMF,“提供定位能力”消息上报UE支持OTDOA的定位能力。
步骤4、当需要下行定位辅助数据时,UE向LMF发送“请求定位辅助数据”消息,该消息用于请求LMF提供OTDOA辅助数据。
步骤5、LMF向基站发送“OTDOA信息请求”消息,该消息用于请求基站提供下行定位辅助数据,例如下行链路(Down Link,DL)定位参考信号(Positioning Reference Signal,PRS)配置数据。
步骤6、基站向LMF发送“OTDOA信息响应”消息,向LMF提供所请求 的下行定位辅助数据,包括PRS配置数据。
步骤7、LMF在“提供定位辅助数据”消息中提供UE所请求的定位辅助数据,其中,携带DL PRS配置数据。
步骤8、基站向UE发送DL PRS信号。
步骤9、UE利用定位辅助数据(例如:PRS配置数据)来测量下行信号以获得定位测量值,例如:参考信号的到达时间差(Reference Signal Time Difference,RSTD),参考信号的接收功率(Reference Signal Received Power,RSRP)。
步骤10、UE向LMF发送“提供定位信息”消息,其中包括测量DL PRS所获得的定位测量值,例如:RSTD、RSRP。
步骤11、LMF根据PRS配置信息、各基站的发送天线的位置,以及UE上报的定位测量值来确定UE的位置。
其中,目前第三代合作伙伴计划(Third Generation partnership project,3GPP)协议中,步骤5中LMF向基站发送的“OTDOA信息请求”消息中只是触发基站向定位服务器提供所请求的下行定位辅助数据,并没有包含建议的下行定位参考信号的配置信息。
综上所述,图2的步骤5中LMF向基站发送的请求消息中只是触发基站向LMF提供所请求的下行定位辅助数据。在基站收到LMF请求消息后,各基站自主确定DL PRS信号的配置。目前的方法存在如下问题:相邻基站可能在相同的时间和频率资源上发送DL PRS,造成相邻基站DL PRS信号相互干扰,导致下行定位测量值性能下降;各基站不能根据UE的定位性能需求来优化配置DL PRS信号。

综上所述,本申请实施例提出了一种LMF协调的定位方案,解决了现有方案可能存在的如下问题:
第一,没有在各个基站之间进行协商DL PRS的配置信息。相邻基站可能在相同的时间和频率资源上的发送DL PRS,造成相邻基站DL PRS信号相互干扰,导致下行定位测量值性能下降;
第二,不能支持各基站根据UE的定位性能需求来优化配置DL PRS信号。例如,可能在有的时候基站配置的DL PRS时间和频率资源不足(如:DL PRS带宽过小、时频域资源密度过低等),不能满足UE的定位性能需求;而有的时候基站配置的DL PRS时间和频率资源过于浪费,由于资源浪费而对无线系统通信造成不利影响。
本领域内的技术人员应明白,本申请的实施例可提供为方法、系统、或计算机程序产品。因此,本申请可采用完全硬件实施例、完全软件实施例、或结合软件和硬件方面的实施例的形式。而且,本申请可采用在一个或多个其中包含有计算机可用程序代码的计算机可用存储介质(包括但不限于磁盘存储器和光学存储器等)上实施的计算机程序产品的形式。
本申请是参照根据本申请实施例的方法、设备(系统)、和计算机程序产品的流程图和/或方框图来描述的。应理解可由计算机程序指令实现流程图和/或方框图中的每一流程和/或方框、以及流程图和/或方框图中的流程和/或方框的结合。可提供这些计算机程序指令到通用计算机、专用计算机、嵌入式处理机或其他可编程数据处理设备的处理器以产生一个机器,使得通过计算机或其他可编程数据处理设备的处理器执行的指令产生用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的 装置。
这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设备以特定方式工作的计算机可读存储器中,使得存储在该计算机可读存储器中的指令产生包括指令装置的制造品,该指令装置实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上,使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的处理,从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的步骤。
显然,本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样,倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内,则本申请也意图包含这些改动和变型在内。
