图1示出了本申请实施例提供的参考信号配置的确定方法适用的一种可能的通信系统的架构，该通信系统可以包括网络设备101和定位管理功能102。定位管理功能102用于根据其他网元(如：基站)的测量结果对终端设备103进行定位计算。定位管理功能102可以是定位管理功能网元(locationmanagement function，LMF)。该通信系统还可以包括终端103和测量网元(或者位置测量网元)104。测量网元也可以称为测量节点。定位管理功能102和测量网元104之间通过SLm接口或NG接口连接。当测量网元是基站，则定位管理功能102和测量网元104之间通过NG接口连接。定位管理功能102和测量网元104之间的接口还可以是Xn接口。网络设备101可以是终端设备103的服务基站，网络设备101为终端设备103提供接入服务，终端设备103接入该网络设备101后可以通过该网络设备101与网络侧进行通信。测量网元104可以是基站或定位测量单元(location measurement unit，LMU)等用于测量定位信息的设备，以下将测量网元测量的定位信息称 为定位测量信息。定位测量信息可以测量终端的参考信号来获取。基站或LMU可以对终端设备103发送的参考信号进行测量获得定位终端设备所需的测量结果。以下以测量网元104为LMU、定位管理功能102和测量网元104之间通过SLm接口为例进行说明。
终端设备103与网络设备101通过蜂窝链路(Uu链路)进行通信，网络设备101与定位管理功能102之间通过NG-C接口进行通信，定位管理功能102与测量网元104之间通过SLm接口进行通信。
可选的，在图1所示的系统架构的基础上，如图2所示，通信系统还可以包括接入管理功能(access management function，AMF)105。AMF105是由运营商提供的控制面网元，负责终端设备103接入运营商网络的接入控制和移动性管理。网络设备101与AMF105之间通过NG-C接口进行通信，AMF105与定位管理功能102之间通过NLs接口进行通信。定位管理功能102与网络设备101之间可以通过AMF105来交互。
终端设备103，又可以称之为终端。终端可以是用户设备(user equipment，UE)、移动台(mobile station，MS)、或移动终端(mobile terminal，MT)等，是一种向用户提供语音或数据连通性的设备，也可以是物联网设备。例如，终端设备103包括具有无线连接功能的手持式设备、车载设备等。目前，终端设备103可以是一种具有无线收发功能的设备，其可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。终端设备可以是UE，其中，UE包括具有无线通信功能的手持式设备、车载设备、可穿戴设备或计算设备。示例性地，UE可以是手机(mobile phone)、平板电脑或带无线收发功能的电脑。终端设备还可以是虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制中的无线终端、无人驾驶中的无线终端、远程医疗中的无线终端、智能电网中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请实施例提供的技术方案中，以用于实现终端的功能的装置是终端或UE为例，来描述本申请实施例提供的技术方案。
基于上述描述，如图3所示，下面对网络设备101的可能形态进行介绍。网络设备为无线接入网(radio access network，RAN)中的节点，又可以称为基站，还可以称为RAN节点(或设备)。网络设备又可以称为网络侧设备。目前，一些网络设备101的举例为：gNB/NG-NB、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)、无线保真(wireless fidelity，Wifi)接入点(access point，AP)、或5G通信系统或者未来可能的通信系统中的网络侧设备等。gNB/NG-NB为5G或NR系统中的网络设备，eNB为LTE中的网络设备。本申请实施例中，用于实现网络设备的功能的装置可以是网络设备，也可以是能够支持网络设备实现该功能的装置，例如芯片系统。该用于实现网络设备的功能的装置也可以被安装在网络设备中。本申请实施例提供的技术方案中，以用于实现网络设备的功能的装置是网络设备或基站为例，来描述本申请实施例提供的技术方案。
在一些部署中，5G或NR系统中的网络设备(例如gNB)可以包括集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)。gNB还可以包括有源天线单元(active antenna unit，AAU)。CU是集中式节点，通过NG接口与核心网(next generation  core，NGC)连接，在接入网内部能够控制和协调多个小区。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU包含协议栈高层控制和数据功能，涉及的主要协议层包括控制面的无线资源控制(radio resource control，RRC)功能和用户面的IP、业务数据适配协议(service data adapt protocol，SDAP)、分组数据汇聚协议(packet data convergence protocol，PDCP)子层功能。DU是分布式单元，广义上，DU实现射频处理功能和无线链路控制(radio link control，RLC)、媒质接入控制(media access control，MAC)以及物理层(PHY)等基带处理功能；狭义上，基于实际设备实现，DU仅负责基带处理功能，AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。DU和AAU之间通过通用公共无线电接口(common public radio interface，CPRI)或eCPRI接口相连。CU和DU之间通过F1接口连接。CU-CP和DU之间的接口可以称为F1-C，CU-UP和DU之间的接口可以称为F1-U。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备。CU/DU具有多种切分方案，不同切分方案的适用场景和性能增益均不同。本申请对此不做限定。
上述提供的系统架构和网络设备的表现形式是本申请实施例可以适用的可能场景，随着网络场景的演进和变换，本申请实施例还可以应用其它可能的网络场景中。以上述提供的系统架构和网络设备的表现形式为例对本申请实施例提供的方案进行详细描述。
基于上述描述，本申请实施例提供一种参考信号配置的确定方法及装置，用于优化上行定位技术以提高上行定位精度。一般来讲，上行定位技术基于参考信号来实现。本申请实施例提供的方法可以应用于任何一种基于终端的参考信号的上行定位技术。在一种可能的实现方式中，采用上行到达时间差(uplink time difference of arrival，UTDOA)技术进行上行定位。该UTDOA技术应用终端的参考信号进行上行定位。UTDOA技术应用于LTE中上行定位。LTE定位中心可以是加强的服务移动定位中心(enhanced serving mobile location center，E-SMLC)。E-SMLC在确定定位方法后向UE的服务基站发送请求信息，并指示UE的服务基站配置UE的探测参考信号(sounding reference signal，SRS)资源。UE的服务基站在收到请求后配置UE的SRS，并向E-SMLC发送UE上行SRS配置信息。E-SMLC将UE上行SRS配置信息发送给一个或多个LMU，以请求测量信息。各个LMU根据UE上行SRS配置信息进行测量，获得定位的测量信息。LMU将测量信息发送给定位中心。定位中心基于多个LMU上报的测量信息计算UE的位置。
如图4所示，在另一种可能的实现方式中，上行定位还可以基于上行到达角(angle of arrival，AOA)来确定UE的位置。例如，图4中包括3个基站：eNB1、eNB2和eNB3。这里的基站即为测量网元。每个基站通过测量UE的上行SRS可以得到UE到基站的AOA。每个基站将测量的UE到基站的AOA发送给定位中心，定位中心根据UE到多个基站的AOA可以计算出UE的位置。
通过上述举例的UTDOA技术和基于上行AOA来进行上行定位的方案来看，上行定位需要定位中心获得参考信号的配置信息，并将参考信号的配置信息发送给测量网元。测量网元根据参考信号的配置信息测量终端的参考信号，并根据测量得到的参考信号确定定 位相关的测量信息。测量网元将定位相关的测量信息发送给定位中心。定位中心根据定位相关的测量信息确定出终端的位置。
如上述对系统架构的描述，本申请实施例中，定位中心可以为定位管理功能102。定位管理功能102，用于向网络设备101请求终端103的参考信号配置，将获得的参考信号配置发送给各个测量网元104，并请求各个测量网元104进行上行定位测量信息的测量。测量网元104用于测量上行定位测量信息，上行定位测量信息可以简述为定位测量信息，上行定位测量信息可以通过测量终端的参考信号来确定。测量网元104可以是基站、定位测量单元LMU。网络设备101用于向定位管理功能102发送终端103的参考信号配置。
参考信号配置用于配置终端的上行参考信号发送，例如包括上行参考信号的资源，上行参考信号的发送位置。上行参考信号可以是SRS。参考信号配置可以是周期性的也可以是非周期性的。
如图5所示，若参考信号配置是周期性的，参考信号配置的确定方法的流程如下所述。
S501、定位管理功能向终端的服务基站发送请求信息，终端的服务基站从定位管理功能接收请求信息。
该请求信息用于请求获取终端的参考信号配置。
S502、终端的服务基站向定位管理功能发送请求响应，定位管理功能从该服务基站接收该请求响应。
该请求响应中包括该终端的参考信号配置。
S503、定位管理功能向一个或多个测量网元发送测量请求，测量网元从定位管理功能接收该测量请求。
该测量请求用于请求获取定位测量信息。该定位测量信息请求中包括终端的参考信号配置。测量网元根据该终端的参考信号配置去获取终端的参考信号，并根据终端的参考信号确定终端的定位测量信息。
S504、测量网元向定位管理功能返回测量响应，测量响应中携带定位测量信息；定位管理功能从测量网元接收测量响应，从测量响应中获取定位测量信息。
图5中以一个测量网元示意，可以理解，实际应用中可以有多个测量网元，多个测量网元执行的操作与示意的这一个测量网元相同。
由于参考信号配置是周期性的，通过S501～S502两个步骤，定位管理功能可以一次性确定参考信号配置。
参考信号配置还可以是非周期性的，终端的服务基站在任意时刻都可能决定终端的非周期性的参考信号配置，如图6所示，本申请实施例中提供的参考信号配置的确定方法能够确定非周期性的参考信号配置。具体流程如下所述。
S601、网络设备确定待定位终端发送非周期性参考信号的第一配置。
网络设备可以是待定位终端的服务基站。
该第一配置(configuration)用于配置终端发送非周期性参考信号。例如，该第一配置可以包括以下一项或多项：发送参考信号的时隙、发送参考信号的时隙模式配置、发送参考信号的符号位置、发送参考信号连续的符号个数。
例如，参考信号为SRS，非周期性参考信号为非周期探测参考信号(aperiodic sounding reference signal，AP-SRS)。非周期性参考信号的第一配置用于配置终端发送SRS，例如，第一配置包括以下一项或多项：发送AP-SRS的时隙(slot)、时隙模式配置(slot format  configuration)、发送AP-SRS的符号位置、AP-SRS连续的符号个数。
S602、网络设备向定位管理功能发送该第一配置，定位管理功能从网络设备接收该第一配置。
定位管理功能会根据第一配置向测量网元请求定位测量信息。网络设备确定待定位终端发送非周期性参考信号的第一配置之后，会向该待定位终端发送非周期性参考信号的第一配置。待定位终端接收该第一配置，按照该第一配置发送非周期性参考信号。
可选的，第一配置可以携带于一个消息中，例如称为上行定位消息。该上行定位消息可以是一种新定义的新无线定位协议A(new radio positioning protocol A，NRPPa)消息，例如，该新定义的NRPPa消息名称可以是上行定位信息指示(UL positioning information indication)。当然该新定义的NRPPa消息名称可以有其它称呼。
该上行定位消息也可以是一种现有的NRPPa消息。例如，现有的NRPPa消息可以是上行定位信息更新(UL positioning information update)消息。
网络设备还可以向定位管理功能发送第一指示信息，该第一指示信息用于指示第一配置为非周期性参考信号的配置。这样能够向定位管理功能指示本次发送第一配置的类型或性质，可以与周期性参考信号的配置作区分。定位管理功能也可以从网络设备接收该第一指示信息，根据该第一指示信息确定该第一配置为非周期性参考信号的配置。
当然，网络设备若不向定位管理功能发送该第一指示信息，网络设备可以根据第一配置的内容确定该第一配置为非周期性的。比如说，若第一配置中不包括发送参考信号的周期，那么定位管理功能可以认为该第一配置为非周期性的。
第一指示信息和第一配置可以携带在同一消息中一并发送。例如，第一指示信息也可以携带于上述上行定位消息中。
通过网络设备向定位管理功能发送非周期性参考信号的配置，定位管理功能能够获取非周期性参考信号的配置，能够利用非周期性参考信号的配置向测量网元获取定位测量信息，由于非周期性参考信号是网络设备随时配置的，该配置能够适应最新的终端上报条件，使用非周期性参考信号的配置进行上行定位，能够提高上行定位的精度。
可选的，在S601之前，还可能包括S600，如下所述。
S600、定位管理功能向网络设备发送第一请求消息，网络设备从定位管理功能接收该第一请求消息。
该第一请求消息用于请求获取待定位终端发送参考信号的配置。
根据该第一请求消息中包括的内容或者第一请求消息所指示的内容的不同，分为几种不同的实现场景。
1)一般情况下，第一请求消息类似于S501中定位管理功能向网络设备发送的请求消息，用于请求获取参考信号的配置，该配置通常为周期性的配置。这种情况下，网络设备在收到该第一请求消息后，会向定位管理功能回复第一响应消息。该第一响应消息用于响应该第一请求消息。并且该第一响应消息中携带待定位终端发送周期性参考信号的配置，记为第二配置。在网络设备向定位管理功能回复第一响应消息之后，执行S601和S602，以实现非周期性参考信号的第一配置。
2)第一请求消息中可以携带一个指示信息，记为第二指示信息。第二指示信息用于指示是否请求获取待定位终端发送非周期性参考信号的配置。例如，该第二指示信息为1bit，1用于指示请求获取待定位终端发送非周期性参考信号的配置，0用于指示不请求获取待 定位终端发送非周期性参考信号的配置。
若该第二指示信息用于指示不请求获取待定位终端发送非周期性参考信号的配置，则后面的操作可以参照第1)种情况。
若该第二指示信息用于指示请求获取待定位终端发送非周期性参考信号的配置，则网络设备可以根据该第二指示信息，向定位管理功能发送响应信息，记为第二响应消息。第二响应消息用于响应该第一请求消息，在该第二响应信息中携带上述第一配置。则上述S602中网络设备向定位管理功能发送该第一配置，定位管理功能从网络设备接收该第一配置，可以通过以下方式实现：网络设备向定位管理功能发送第二响应消息，该第二响应消息中携带第一配置，定位管理功能从网络设备接收该第二响应消息，从第二响应消息中获取该第一配置。另外，网络设备在接收到第二指示信息之后，也可以自行判断是否需要配置终端的非周期性参考信号发送，若需要，则向定位管理功能发送第二响应消息中携带上述第一配置。
3)第一请求消息中可以携带一个指示信息，记为第三指示信息。第三指示信息用于指示请求获取的参考信号配置的类型。例如，该参考信号配置的类型包括以下任意一种或多种的组合：待定位终端发送周期参考信号的配置、或待定位终端发送非周期参考信号的配置。即，可以有三种情况：该第三指示信息可以指示请求获取非周期性参考信号的第一配置；该第三指示信息可以指示请求获取周期性参考信号的第二配置；该第三指示信息用于指示请求获取非周期性参考信号的第一配置，以及用于指示获取周期性参考信号的第二配置。
例如该第三指示信息的大小可以为2bit。2bit可以用于指示参考信号配置的三种类型。
若第三指示信息用于请求获取周期性参考信号的第二配置，则后面的操作可以参照第1)种情况。
若第三指示信息可以指示请求获取非周期性参考信号的第一配置，网络设备可以根据该第三指示信息，向定位管理功能发送响应信息，记为第二响应消息。第二响应消息用于响应该第一请求消息，在该第二响应信息中携带上述第一配置。则上述S602中网络设备向定位管理功能发送该第一配置，定位管理功能从网络设备接收该第一配置，可以通过以下方式实现：网络设备向定位管理功能发送第二响应消息，该第二响应消息中携带第一配置，定位管理功能从网络设备接收该第二响应消息，从第二响应消息中获取该第一配置。另外，网络设备在接收到第三指示信息之后，也可以自行判断是否需要配置终端的非周期性参考信号发送，若需要，则向定位管理功能发送第二响应消息中携带上述第一配置。
若第三指示信息用于指示请求获取非周期性参考信号的第一配置，以及用于指示获取周期性参考信号的第二配置，则网络设备可以在向定位管理功能发送的响应信息中携带上述第一配置和第二配置。或者，网络设备可以在向定位管理功能发送的响应信息中携带上述第二配置，并在后续S602中向定位管理功能发送第一配置。另外，网络设备在接收到第三指示信息之后，也可以自行判断是否需要配置终端的非周期性参考信号发送，若需要，则向定位管理功能发送上述第一配置。
在上述第1)～3)种情况下，若指示信息指示请求获取非周期性参考信号的配置，可以在网络设备配置周期性参考信号的基础上实现。例如，当指示信息指示请求获取非周期性参考信号的配置的情况下，网络设备可以向定位管理功能发送周期性和非周期性参考信号的配置。或者，在上述第1)～3)种情况下，若指示信息指示请求获取非周期性参考信 号的配置，也可以指示网络设备只请求获取非周期性参考信号的配置，不需要获取周期性参考信号的配置。那么网络设备只需要向定位管理功能发送非周期性参考信号的配置，不需要向定位管理功能发送周期性参考信号的配置。
在S602之后，还可能包括以下步骤。
S603、定位管理功能向测量网元发送测量请求，测量网元从定位管理功能接收该测量请求。
该测量请求用于请求获取定位测量信息。该测量请求中携带待定位终端发送非周期性参考信号的第一配置。测量网元根据第一配置接收终端发送的非周期性参考信号。测量网元根据该非周期性参考信号确定终端的定位测量信息。例如终端的定位测量信息包括终端的位置。其中，该定位测量信息的一种可能的举例为参考信号的参考信号接收功率(reference signal received power，RSRP)。基站配置UE发送SRS后,测量网元测量参考信号的RSRP，测量网元将测量的RSRP上报给定位管理功能。测量请求可以是测量更新(measurement update)消息。在测量更新消息中选携带该第一配置。
S604、测量网元向定位管理功能发送测量响应，定位管理功能从测量网元接收该测量响应。
该测量响应中携带该终端的定位测量信息。
图6中用一个测量网元示意，可以理解的是，实际应用中可能存在多个测量网元，该多个测量网元的操作与该一个测量网元的操作相同。
