Description

定位的方法和通信装置
本申请要求于2019年08月30日提交国家知识产权局、申请号为201910813973.X、申请名称为“定位的方法和通信装置”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，更具体地，涉及一种定位的方法和通信装置。
背景技术
在无线通信技术中，定位一直是第三代合作伙伴计划(the third partnership project,3GPP)的一个重要内容。在长期演进(long term evolution，LTE)的版本15(release 15,Rel15)以后以及新空口(new radio，NR)的版本15中，接入第五代核心网(the fifth generation core,5GC)的定位都采用了由核心网的定位管理功能(location management function,LMF)控制，接入网和终端设备辅助的架构。在此架构下，LMF与终端设备的服务小区和邻小区之间交互小区信息，并与终端设备之间完成终端设备的能力信息、用于定位的辅助信息以及测量结果的交互。最后，LMF基于各小区的小区信息以及终端设备对各小区的定位参考信号的测量和上报，完成对终端设备的定位。
但是，随着NR技术的演进，出现了更多的应用场景。这些应用场景对于定位的时延提出了更高的要求。而在现有的基于核心网LMF的架构中，由于接入网和终端设备与LMF的信息交互会带来较大时延，因此，不能满足NR对于定位的低时延的需求。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
参见图1，图1是适用于本申请实施例的通信系统100的一种架构的示例。如图1所示，通信系统100包括核心网、无线接入网(radio access network,RAN)和终端设备。其中，核心网包括接入和移动性管理功能(access and mobility management function,AMF)、定位管理功能(location management function,LMF)、统一数据管理(unified data manage,UDM)、网关移动位置中心(gateway mobile location center,GMLC)和位置检索功能(location retrieval function,LRF)等功能。NG-RAN包括一个或多个ng-eNB和gNB。其中，ng-eNB是接入5G核心网的长期演进(long term evolution,LTE)基站，gNB是接入5G核心网的5G基站。另外，通信系统100中还可以包括一个或多个终端设备。NG-RAN通过NG-C接口经由AMF连接到核心网。终端通过LTE-Uu和NR-Uu分别经由ng-eNB和gNB连接到RAN。
需要说明的是，图1中的核心网5GC用虚线示出，表示通信系统100可以仅包括终端设备和RAN。在本申请的技术方案中，5GC是可选的。或者说，本申请提供的定位的方法中，可以不需要核心网的任何网元的参与。
另外，图1中的外部客户端(external client)，可以是连到互联网的应用程序，该应用程序通过互联网向5G核心网请求终端位置信息，5G核心网的网关移动位置中心(gateway mobile location center,GMLC)负责外部客户端位置请求的处理。
可选地，在另一种架构中，核心网可以完成对接入网设备定位的选取、授权以及定位流程的控制，例如，定位流程的启动以及定位结果的获取。而定位的过程完全由接入网完成，不需要核心网的参与。
另外，应理解，图1中所示的各网元之间的接口名称仅是作为示例。在不同的通信系统中，或者随着通信系统的演进，图1中所示的各网元之间的接口也可以不同于图1所示，本文不作限定。
本申请中提及的无线接入网设备是一种部署在RAN中满足5G标准或者下一代通信标准的为终端设备提供无线通信功能的装置。无线接入网设备可以包括各种形式的宏基站、微基站(也称为，小站)、中继站、接入点，可穿戴设备，车载设备。gNB还可以是传输接收节点(transmission and reception point,TRP)等。
本申请中的终端设备包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备。例如，终端设备可以指用户设备(user equipment,UE)、接入终端、用户单元、用户站、移动站(mobile station,MS)、移动台、 远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话(cellular phone)、智能电话(smart phone)、无绳电话、会话启动协议(session initiation protocol,SIP)电话、无线本地环路(wireless local loop,WLL)站、个人数字处理(personal digital assistant,PDA)、车载设备、可穿戴设备、平板型电脑、无线调制解调器(modem)、手持设备(handset)、膝上型电脑(laptop computer)、机器类型通信(machine type communication,MTC)终端，5G网络或者未来演进的公用陆地移动通信网络(public land mobile network,PLMN)中的终端设备等，本申请对此并不限定。
下面介绍本申请提供的定位的方法。
参见图2，图2是本申请提供的定位的方法的示意性流程图。
210、服务小区向终端设备发送一个或多个PRS配置信息。
相应地，终端设备从服务小区接收该一个或多个PRS配置信息。
本申请中，服务小区向终端设备发送PRS配置信息，也即，服务小区的接入网设备向终端设备发送PRS配置信息。为了描述上的简洁，本文简化了描述。
另外，关于服务小区和邻小区之间的信息交互的描述也是类似。例如，服务小区向邻小区发送信息，或者服务小区从邻小区接收信息，也即服务小区的接入网设备向邻小区的接入网设备发送信息，或者，服务小区的接入网设备从邻小区的接入网设备接收信息。
此外，终端设备和服务小区或邻小区之间的信息和信号的交互也是类似的。例如，终端设备从服务小区接收信息，也即终端设备从服务小区的接入网设备接收信息。或者，终端设备从服务小区或邻小区接收PRS，也即终端设备从服务小区或邻小区的接入网设备接收PRS。或者，终端设备向服务小区发送信息，也即，终端设备向服务小区的接入网设备发送信息。
上述说明对于本申请中的各实施例均是适用的，以下不再说明。
其中，该一个或多个PRS配置信息来自服务小区和/或一个或多个邻小区，以及，该一个或多个PRS配置信息对应的PRS来自服务小区和/或所述一个或多个邻小区。每个PRS配置信息可以包括如下信息的一项或多项：周期性PRS的配置信息、半持续PRS的配置信息或非周期PRS的配置信息。
应理解，周期性PRS是指周期性发送的PRS。半持续PRS是指半持续发送的PRS。非周期PRS是指非周期发送的PRS。
220、终端设备根据该一个或多个PRS配置信息，获得对服务小区以及该一个或多个邻小区的PRS的测量结果。
终端设备从服务小区接收该一个或多个PRS配置信息，进而获知该一个或多个PRS配置信息各自对应的小区的PRS的配置。通过接收并测量服务小区以及该一个或多个邻小区的PRS，终端设备获得服务小区以及该一个或多个邻小区的PRS的测量结果。
230、终端设备向服务小区发送测量结果。
240、服务小区根据测量结果，对终端设备进行定位。
服务小区根据终端设备上报的测量结果，可以完成对终端设备的定位。或者，服务小区接收到测量结果之后，将测量结果发送给具有定位功能的邻小区。该具有定位功能的邻小区根据测量结果计算终端设备的位置，也可以完成对终端设备的定位。最后，该具有定 位功能的邻小区可以将计算得到的终端设备的位置信息提供给服务小区。其中，测量结果包括哪些测量，以及服务小区如何根据测量结果得到终端设备的定位，请参考下方实施例的描述。
因此，在本申请提供的由接入网对终端设备进行定位的方法中，服务小区的一个或多个邻区可以辅助服务小区对终端设备进行定位。在整个定位流程中，不需要核心网的参与。由接入网对终端设备进行定位，一方面可以降低定位的时延，另一方面可以避免终端设备暴露在公网中。
针对终端设备的服务小区是否具有定位功能，下文分两种场景分别详细说明接入网对终端设备进行定位的详细流程。
场景1
终端设备的服务小区具有定位功能。
参见图3，图3为本申请提供的定位的方法的一个示意性流程图。
301、服务小区获取一个或多个邻小区的PRS配置信息。
具体地，参与定位的一个或多个邻小区向服务小区发送各自的PRS配置信息。
可选地，在一种实现方式中，参与定位的邻小区向服务小区发送小区信息，小区信息包括邻小区的PRS配置信息。此外，小区信息还可以包括该邻小区的位置信息和小区的定时信息等。
其中，每个邻小区的PRS配置信息可以包括如下一项或多项：周期PRS配置信息、半持续PRS配置信息或非周期PRS配置信息。
应理解，当一个邻小区的PRS配置信息仅包括某一种类型的PRS配置信息时，表示该邻小区发送相应类型的PRS。例如，如果一个邻小区的PRS配置信息仅包括周期PRS配置信息时，表示该邻小区发送周期性PRS。当一个邻小区的PRS配置信息包括两种或两种以上的PRS配置信息时，表示该邻小区可以在不同的时段发送不同类型的PRS。例如，如果一个邻小区的PRS配置信息包括非周期PRS配置信息和半持续PRS配置信息，表示该邻小区可以基于服务小区的请求发送非周期PRS和半持续PRS。
进一步地，每个邻小区的PRS配置信息可以包括如下信息：子载波间隔、A点频点、slot内时频域资源、端口数、序列以及准共址(quasi co-loacted,QCL)信息等。
例如，PRS的子载波间隔可以为30KHz。
A点频点可以用邻小区的绝对无线频道编号(absolute radio frequency channel number,ARFCN)表示。例如，A点频点可以为ARFCN 653334，表明A点绝对频点为3800.01MHz。
时频域资源的时域资源可以为时域符号所占用的一个时隙内的符号5,6,7,8,9,10,11,12,13。频域资源可以从载波公共资源块(common resource block,CRB)的CBR#2开始，占用192个RB。
进一步地，对于周期性PRS和半持续PRS，时域资源还可以包括周期以及周期内的偏移。
例如，周期可以为10ms，周期内的偏移可以为2ms。当子载波间隔为30KHz时，表示PRS的发送时机为每个系统帧的第5个时隙。又例如，周期可以为40个时隙，周期内的偏移可以为4个时隙，则表示PRS的发送时机为偶数系统帧的第5个时隙。
端口数可以为1。
序列初始化扰码索引可以为139。基于扰码索引可以生成每个时隙、每个符号上的序列。
QCL可以为该邻小区的同步信号块(SS/PBCH block,SSB)#2，表明邻小区的PRS与SSB#2QCL。
邻小区的位置信息可以为邻小区的地理位置，例如，经纬度坐标。
小区的定时信息可以为系统帧号(system frame number,SFN)初始化时间。
302、服务小区向终端设备发送服务小区以及该一个或多个邻小区的PRS配置信息。
服务小区从该一个或多个邻小区接收PRS配置信息之后，向终端设备发送该一个或多个邻小区的PRS配置信息以及服务小区的PRS配置信息。
换句话说，服务小区向终端设备发送所有参与定位的小区的PRS配置信息。
可选地，为了达到对终端设备进行定位的目的，服务小区向终端设备发送多个小区的PRS配置信息，使得终端设备可以对多个小区的PRS进行测量，从而由接入网根据测量结果对终端设备定位。其中，所述多个(三个或三个以上)小区可以包括服务小区以及部分邻小区。
在一些可能的场景下，服务小区向终端设备发送一个或者两个小区的PRS配置信息。终端设备通过对一个小区的不同波束发送的PRS进行测量，得到的测量结果也可以用于对终端设备的定位，相对于前者，定位精度可能略低。
303、服务小区向终端设备发送上报配置信息。
相应地，终端设备从服务小区接收上报配置信息。
除了步骤302中的PRS配置信息，服务小区还需要向终端设备下发上报配置信息，用于指示终端设备如何上报测量结果。
可选地，上报配置信息可以包括如下信息中的一项或多项：
测量结果应该包括的测量量、上报测量结果所采用的信道、上报测量结果的周期性以及上报测量结果所用的各小区的PRS资源。
可选地，测量量可以包括参考信号时间差(reference signal time difference,RSTD)、参考信号接收质量(reference signal received quality,RSRQ)以及参考信号接收功率(reference signal received power,RSRP)等。
为了描述上的方便，以下将上报测量结果所采用的信道称为上报信道。
可选地，上报信道可以包括物理上行控制信道(physical uplink control channel,PUCCH)、物理上行共享信道(physical uplink shared channel,PUSCH)。
可选地，上报的方式可以包括周期性上报、半持续上报或者非周期上报。
可选地，上报测量结果所用的各小区的PRS资源可以如下：
周期性上报一般基于周期性PRS；
半持续上报可以基于周期性PRS或半持续PRS；
非周期上报可以基于周期性PRS、半持续PRS或非周期PRS。
应理解，步骤302中的PRS配置信息和步骤303中的上报配置信息可以由服务小区一起发送给终端设备，也可以分开发送，本申请不作限定。当分开发送时，也不应限定发送的先后顺序。
服务小区向终端设备发送PRS配置信息和上报配置信息之后，可以执行步骤340。
304、服务小区向该一个或多个邻小区发送请求消息。
其中，请求消息用于请求这些邻小区向终端设备发送半持续PRS或非周期PRS。
具体地，服务小区发送给邻小区的请求消息中可以包括如下信息中的一项或多项：发送半持续PRS的次数、发送半持续PRS的时长，以及发送非周期PRS的时隙。
305、服务小区激活终端设备对半持续PRS或非周期PRS的接收。
对于发送半持续PRS或非周期PRS的邻小区，服务小区可以通过MAC CE或DCI激活终端设备对半持续PRS或非周期PRS的接收。
可选地，在一种实现中，对于半持续PRS，服务小区可以通过MAC CE激活终端设备对于半持续PRS的接收。
例如，服务小区向终端设备发送MAC CE，其中，该MAC CE用于激活服务小区以及上述一个或多个邻小区中的半持续PRS。激活之后，终端设备认为半持续PRS是周期发送的。
在激活半持续PRS之后，服务小区也可以根据需要，通过MAC CE去激活半持续PRS的发送。去激活之后，终端设备认为半持续PRS不再发送。
对于非周期PRS，服务小区可以通过DCI激活终端设备对于非周期PRS的接收。
例如，服务小区向终端设备发送DCI，其中，该DCI用于激活服务小区以及上述一个或多个邻小区中的非周期PRS。激活之后，终端设备接收一次非周期PRS。
对于周期PRS，终端设备周期性接收。
306、服务小区激活终端设备的半持续上报或非周期上报。
如步骤303所述，上报配置信息中包括上报的周期性。上报的周期性可以包括周期上报、半持续上报以及非周期上报。
其中，对于半持续上报和非周期上报，服务小区需要通过MAC CE或者DCI激活。
在一种实现中，服务小区可以通过MAC CE激活基于PUCCH的半持续上报。
例如，服务小区可以向终端设备发送MAC CE，该MAC CE用于激活终端设备基于PUCCH进行半持续上报。激活之后，终端设备周期性上报测量结果。
可选地，激活半持续上报之后，服务小区可以根据需要通过MAC CE去激活半持续上报。去激活之后，终端设备不再上报。
可选地，用于激活半持续上报的MAC CE和用于激活半持续PRS的MAC CE可以分开发送，也可以一起发送。
在一种实现中，服务小区也可以通过DCI激活基于PUCCH或PUSCH的非周期上报。
例如，服务小区向终端设备发送DCI，该DCI用于激活终端设备基于PUCCH或PUSCH进行非周期上报。
可选地，服务小区向终端设备发送DCI，默认表示终端设备可以从PUCCH和PUSCH中选择一个上报。或者，服务小区向终端设备发送DCI，DCI中可以携带指示信息，指示信息用于指示上报信道采用PUCCH或是PUSCH。例如，DCI中携带比特“0”，表示服务小区指示终端设备采用PUCCH进行非周期上报。DCI中携带比特“1”，表示服务小区指示终端设备采用PUSCH进行非周期上报。
应理解，对于非周期上报，服务小区通过DCI激活之后，终端设备只上报一次。
可选地，如果非周期上报基于非周期PRS，则用于激活非周期上报的DCI和用于激 活非周期PRS的DCI为同一个DCI。
307、服务小区以及该一个或多个邻小区向终端设备发送PRS。
在步骤307，所有参与定位的小区向终端设备发送PRS。
其中，对于发送半持续PRS或非周期PRS的邻小区，根据步骤304中从服务小区接收到的请求消息，根据服务小区指定的半持续PRS的次数以及时长向终端设备发送半持续PRS，或者在服务小区指定的时隙向终端设备发送非周期PRS。
对于发送周期性PRS的小区而言，根据PRS配置信息向终端设备周期发送PRS即可。
相应地，终端设备接收并测量服务小区以及该一个或多个邻小区发送的周期PRS、半持续PRS或非周期PRS，得到测量结果。
308、终端设备向服务小区发送测量结果。
根据步骤303中接收到的上报配置信息，终端设备按照服务小区指定的上报信道以及上报的周期性向服务小区发送测量结果。
进一步地，如果服务小区指示终端设备半持续上报或者非周期上报，终端设备根据步骤306中所述的半持续上报或者非周期上报的激活以及去激活向服务小区上报测量结果。
可选地，在步骤308中，终端设备将测量结果封装后，通过上行控制信息(uplink control information,UCI)发送给服务小区。
309、服务小区根据测量结果对终端设备进行定位。
服务小区接收到终端设备的测量结果之后，结合步骤310中从该一个或多个邻小区接收到的小区信息，例如各邻小区的位置信息、小区定时信息等，对终端设备进行定位。
例如，当测量结果为参考信号接收质量(reference signal received quality,RSRQ)，服务小区可以根据该测量结果和各邻小区的位置信息、小区定时信息，得到终端设备的定位信息，定位算法包括多种实现方法，具体可以参考现有技术的描述。
在场景1中，服务小区具有定位功能。服务小区获取其一个或多个邻小区的PRS配置信息，并和服务小区的PRS配置信息一起发送给终端设备。进一步地，服务小区请求该一个或多个邻小区向终端设备发送PRS，从而可以和服务小区一起向终端设备发送可供测量的PRS，由终端设备对服务小区以及该一个或多个邻小区的PRS进行测量。终端设备完成测量之后，基于服务小区的上报配置信息，向服务小区上报测量结果。服务小区基于该测量结果，可以完成对终端设备的定位。
通过以上步骤310-380，不需要核心网的参与，接入网可以完成对终端设备的定位。
场景2
服务小区不具有定位功能，而服务小区的某个邻小区具有定位功能。
为了描述上的清楚，以下将该服务小区的具有定位功能的邻小区记作第一邻小区。应理解，第一邻小区可以是服务小区的所有邻小区中任意一个具有定位功能的小区。
可选地，在一种可能的情况下，服务小区可以有多个具有定位功能的邻小区，此时，第一邻小区可以为该多个具有定位功能的邻小区中的任意一个。
下面结合图4，对场景2的定位流程进行说明。
参见图4，图4为本申请提供的定位的方法的另一个示意性流程图。
401、服务小区通过第一邻小区获取一个或多个PRS配置信息。
其中，所述一个或多个PRS配置信息来自服务小区、第一邻小区以及一个或多个其 它邻小区。
或者说，所述一个或多个PRS配置信息来自服务小区以及一个或多个邻小区。所述一个或多个邻小区包括第一邻小区。也即，服务小区的一个或多个邻小区包括第一邻小区和其它邻小区。
具体地，在步骤401之前，服务小区以及其它邻小区向第一邻小区发送各自的PRS配置信息，再由第一邻小区将参与定位的小区的PRS配置信息提供给服务小区。
应理解，第一邻小区向服务小区提供的一个或多个PRS配置信息，可以包括服务小区、第一邻小区以及一个或多个其它邻小区的PRS配置信息。
在一种实现中，服务小区向第一邻小区发送服务小区的消息信息，服务小区的小区信息包括服务小区的PRE配置信息、小区的位置信息以及小区定时信息等。同时，其它邻小区也向第一邻小区发送自己的小区信息，小区信息包括PRS配置信息、小区的位置信息以及小区定时信息等。
第一邻小区从服务小区以及一个或多个其它邻小区接收该一个或多个PRS配置信息，并将该一个或多个PRS配置信息提供给服务小区。
应理解，由于第一邻小区是具有定位功能的小区，因此，服务小区以及其它邻小区中参与定位的小区是由第一邻小区确定的。服务小区和其它邻小区将各自的小区信息发送给第一邻小区。第一邻小区获取到服务小区以及一个或多个邻小区的PRS配置信息后，只需要向服务小区提供所有参与定位的小区的PRS配置信息。
相应地，服务小区只需要向终端设备透传第一邻小区确定出的参与定位的小区的PRS配置信息即可。
可选地，在另一种实现中，第一邻小区获取到服务小区以及其它邻小区的小区信息之后，每个小区的位置信息、小区定时信息可以由第一邻小区保留，而不需要提供给服务小区，这是与场景1不同。
在场景1中，所有邻小区都将各自的小区信息提供给服务小区，其中，每个邻小区的小区信息包括该邻小区的位置信息、定时信息。
区别的原因在于，在场景2中，服务小区不具有定位功能，而第一邻小区具有定位功能。第一邻小区保留服务小区以及其它邻小区的位置信息和定时信息，后续可以用于对终端设备进行定位，而不需要提供给服务小区。
服务小区从第一邻小区接收一个或多个PRS配置信息。
402、服务小区向终端设备发送服务小区以及该一个或多个邻小区的PRS配置信息。
403、服务小区向终端设备发送上报配置信息。
步骤402-403可以分别参见上文的步骤302-303，这里不再赘述。
404、服务小区通过第一邻小区向发送半持续PRS或非周期PRS的邻小区发送请求消息。
对于发送半持续PRS或非周期PRS的邻小区，服务小区需要向这些邻小区发送请求消息，请求消息中携带如下信息中的一项或多项：发送半持续PRS的次数、发送半持续PRS的时长，以及发送非周期PRS的时隙。
405、服务小区激活终端设备对半持续PRS或非周期PRS的接收。
406、服务小区激活半持续上报或非周期上报。
407、服务小区以及该一个或多个邻小区向终端设备发送PRS。
终端设备接收并测量服务小区以及该一个或多个邻小区的PRS。
408、终端设备向服务小区发送测量结果。
服务小区从终端设备接收测量结果。
步骤405-408分别参见步骤305-308的说明，不再赘述。
409、服务小区向第一邻小区发送该测量结果。
410、第一邻小区根据测量结果，对终端设备进行定位。
第一邻小区根据测量结果，以及步骤401中从其它邻小区接收到的其它邻小区的位置信息、定时信息等，结合第一邻小区的位置信息、定时信息，对终端设备进行定位。
在场景2中，服务小区不具有定位功能，而服务小区的一个邻小区(例如，第一邻小区)具有定位功能。服务小区通过第一邻小区获取参与定位的小区的PRS配置信息，并将该参与定位的小区的PRS配置信息发送给终端设备。进一步地，服务小区通过第一邻小区请求其它邻小区向终端设备发送PRS。终端设备接收并测量服务小区以及该一个或多个邻小区的PRS。终端设备完成测量之后，基于服务小区的上报配置信息，向服务小区上报测量结果。服务小区将该测量结果提供给第一邻小区，由第一邻小区对终端设备进行定位。
可见，在服务小区不具有定位功能，而其邻小区具有定位功能的场景下，不需要核心网的参与，接入网也可以完成对终端设备的定位。
考虑到终端设备在上报测量结果(例如，场景1的步骤308或场景2的步骤408)时，上报信道可能会与携带混合自动重传请求肯定应答(hybrid automatic repeat request acknowledgement,HARQ-ACK)、调度请求(scheduling request,SR)或信道状态信息(channel state information,CSI)的PUCCH，或者与携带数据或CSI的PUSCH发生时域碰撞，本申请的方案进一步提出处理这种碰撞的方法。
终端设备可以按照测量量、CSI、HARQ-ACK以及SR的优先级顺序，对测量量、CSI、HARQ-ACK以及SR进行合并，再向服务小区上报合并后的信息。
可选地，测量量和CSI的优先级可以是预先定义的，或者也可以由终端设备定义。
例如，所有测量量的优先级低于CSI，或者所有测量量的优先级高于CSI，或者测量量的优先级介于L1-RSRP与其它CSI之间。
可选地，当发生碰撞时，如果有CSI，终端设备首先合并测量量和CSI，得到第一信息(或者称为，合并后的CSI)。进一步地，再将合并后的CSI和HARQ-ACK、SR进行合并，得到所述合并后的信息。其中，合并后的CSI和HARQ-ACK、SR的合并处理可以参见3GPP标准协议TS 38.213 9.2.5-9.2.6。
可选地，当发生碰撞时，如果没有CSI，终端设备可以直接合并测量量和HARQ-ACK、SR或数据，再向服务小区上报合并后的信息。
可选地，测量结果中可能包括多个测量量，CSI包括多个部分(例如，part 1,part 2)。上述定义测量量和CSI的优先级包括定义该多个测量量和CSI的所述多个部分的优先级。当发生碰撞时，按照该多个测量量和CSI的多个部分的优先级进行合并。
例如，上报信道无法将测量量和CSI全部传输(或者说，测量量和CSI的比特数超出了上报信道的最大码率)时，终端设备可以丢弃优先级较低的测量量或者CSI的优先级较 低的部分。也即，这些优先级较低的测量量或者CSI的部分不予上报。终端设备将优先级较高的测量量和CSI的优先级较高的部分进行合并，并向服务小区上报合并后的信息。
此外，终端设备向服务小区上报合并后的信息时，可能重新选择PUCCH或PUSCH用于发送合并后的信息。
可选地，终端设备可能需要合并测量量和SR，或者合并测量量和HARQ-ACK，或者上报信道可能为PUCCH，或者上报信道可能为PUSCH。在这些不同的情况下，可以分别有不同的合并规则，本文不作限定。
通过设计测量量和CSI、HARQ-ACK、SR或数据等的合并规则，可以在碰撞发生时，保证优先级相对较高的信息被上报，可以优化上报机制。
以上结合图3和图4，对本申请提供的由接入网对终端设备进行定位的方法作了详细说明。
下面结合图5和图6进行举例说明。
参见图5，图5是服务小区具有定位功能的定位流程的一个示例。
501、服务小区的gNB基于XnAP协议通过Xn接口，从一个或多个邻小区的gNB接收该一个或多个邻小区的小区信息。
其中，每个邻小区的小区信息包括该邻小区的PRS配置信息、位置信息和定时信息。。
502、服务小区的gNB通过RRC协议向UE发送上报配置信息以及参与定位的小区的PRS配置信息。
其中，参与定位的小区可以包括服务小区以及该一个或多个邻小区。
应理解，在本实施例中，PRS配置信息和上报配置信息可以通过一条RRC消息发送给UE。
UE从服务小区的gNB接收上报配置信息以及服务小区和该一个或多个邻小区的PRS配置信息。
503、服务小区的gNB基于XnAP协议通过Xn接口向邻小区的gNB发送请求消息。
其中，请求消息用于请求该一个或多个邻小区发送半持续PRS或非周期PRS。
504、服务小区的gNB激活UE接收半持续PRS或非周期PRS。
具体地，服务小区的gNB可以通过MAC CE激活UE接收半持续PRS，或者通过DCI激活UE接收非周期PRS。
505、服务小区的gNB激活UE进行半持续上报或非周期上报。
可选地，服务小区的gNB可以基于MAC CE或DCI激活UE进行半持续上报或非周期上报。
506、服务小区的gNB和该一个或多个邻小区的gNB向UE发送PRS。
其中，被配置为发送半持续PRS的邻小区，根据服务小区的gNB的请求，在指定时间发送PRS，并发送指定次数。被配置为发送非周期PRS的邻小区，根据服务小区的请求，在指定时间(例如，在指定的时隙)发送PRS。
相应地，UE根据步骤502中接收到的服务小区和各邻小区的PRS配置信息，接收并测量服务小区以及各邻小区的PRS。对于服务小区或任意一个邻小区而言，其发送的PRS可以是周期PRS、非周期PRS或半持续PRS，具体取决于各小区的PRS的配置。
507、UE向服务小区的gNB发送测量结果。
UE根据步骤502中从服务小区的gNB接收到的上报配置信息，上报测量结果。
具体地，如果服务小区的gNB配置UE周期性上报，UE根据步骤502中的上报配置信息，周期上报测量结果。
如果服务小区的gNB配置UE进行半持续上报或非周期上报，UE根据步骤502中的上报配置信息，在步骤504中激活的上报信道上向服务小区的gNB上报测量结果。
可选地，UE在上报测量结果时，如果上报信道与携带CSI、HARQ-ACK或SR的PUCCH发生时域碰撞，或者与携带数据或CSI的PUSCH发生碰撞，UE按照上文描述的处理碰撞的流程进行处理，这里不再赘述。
508、服务小区的gNB根据UE上报的测量结果，计算UE的位置。
可选地，服务小区的gNB计算得到UE的位置信息之后，将该位置信息提供给UE。
509、服务小区的gNB通过RRC消息或者MAC CE，向UE发送计算得到的UE的位置信息。
参见图6，图6是服务小区不具有定位功能的定位流程的一个示例。
601、服务小区向第一邻小区发送服务小区的PRS配置信息，一个或多个其它邻小区向第一邻小区发送各自的PRS配置信息。
第一邻小区从服务小区以及所述一个或多个其它邻小区接收各小区的PRS配置信息。

应理解，所述一个或多个小区信息来自服务小区以及该一个或多个邻小区。其中，所该一个或多个邻小区包括第一邻小区。
换句话说，第一邻小区的gNB从服务小区以及所述一个或多个其它邻小区的gNB获取到各小区的PRS配置信息之后，向服务小区的gNB提供参与定位的各小区的PRS配置信息。其中，参与定位的小区可以为服务小区以及该一个或多个邻小区中的部分或全部，这里不作限定。
其中，每个小区(例如，服务小区或邻小区)的小区信息包括该该小区的PRS配置信息、位置信息以及定时信息。
可选地，第一邻小区的gNB从服务小区以及该一个或多个其它邻小区的gNB接收到小区信息之后，第一邻小区向服务小区的gNB提供的小区信息中不包含各参与定位的小区的位置信息。或者，第一邻小区的gNB向服务小区的gNB只提供各参与定位的小区的PRS配置信息。

应理解，图5和图6所示流程中的各个步骤可以分别参考图3和图4中相应步骤的说明，为了避免赘述，不再展开详细说明。
需要说明的是，在本申请的各实施例中，终端设备向服务小区上报测量结果时，是由终端设备的物理层对测量结果进行封装后通过上行控制信息(uplink control information,UCI)发送给服务小区的。
而在现有的通过核心网的LMF进行定位的机制中，是由终端设备的长期演进定位协议(long term evolution positioning protocol,LPP)层对测量结果封装后通过非接入层(non-access stratum,NAS)信令并进一步经由RRC/PDCP/RLC/MAC层封装后映射到逻辑信道中的上行共享信道(uplink-shared channel,UL-SCH)，经由层1(PHY层，物理层)发送给基站，基站将数据包经由AMF发送LMF的。协议栈如图7所示。
参见图7，图7为LMF和终端设备(以UE为例)的通信协议栈的示意图。UE和LMF之间通过LPP消息传递信息，经由基站透明转发，并经由AMF传递至LMF处。
而本申请中利用终端设备的物理层进行上报，终端设备可以更快的将测量结果反馈给基站。同时，基站对物理层信道数据的解包也更快，基站可以更快地获取到终端测量结果。
