具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
本申请实施例描述的网络架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。在本公开使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开可能采用术语第一、第二等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开范围的情况下，第一参数也可以被称为第二参数，类似地，第二参数也可以被称为第一参数。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
图1示出了本申请一个示例性实施例提供的通信网络架构的示意图。该通信网络架构可以包括：核心网11、接入网12和终端13。
核心网11中包括若干核心网设备。核心网设备的功能主要是提供用户连接、对用户的管理以及对业务完成承载，作为承载网络提供到外部网络的接口。例如，第五代移动通信技术(5th Generation，5G)新空口(New Radio，NR)系统的核心网中可以包括接入和移动性管理功能(Access and Mobility Management Function，AMF)实体、用户平面功能(User Plane Function，UPF)实体和会话管理功能(Session Management Function，SMF)实体等设备。由于蜂窝网络所使用的无线电磁波信号不但可以用于无线数据传输和通信，同时还具有环境感知能力，例如，用户的动作或者手势识别、呼吸监测、终端移动速度测量、环境成像、天气监测等。因此在未来的蜂窝网络可以考虑不只是用于通信和数据传输，还可以用于感知信息的获取。
当前，正在讨论在B5G网络中支持感知能力，通过增加感知控制网元(Sensing Function，SF)及相应 流程在3GPP网络中支持感知功能。在感知功能的实现中，可以根据感知目标的不同，将感知测量划分为有源感知和无源感知。其中，有源感知的感知目标是UE，即，是UE级别的感知；无源感知的感知目标是目标区域或者目标对象，即，区域级别的感知没有特定的UE，不属于3GPP。
接入网12中包括若干接入网设备14。5G NR系统中的接入网可以称为新一代无线接入网(New Generation-Radio Access Network，NG-RAN)。接入网设备14是一种部署在接入网12中用以为终端13提供无线通信功能的装置。接入网设备14可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备接入网设备功能的设备的名称可能会有所不同，例如在5G NR系统中，称为5G基站(Next Generation Node B，gNodeB或gNB)。随着通信技术的演进，“接入网设备”这一名称可能会变化。为方便描述，本公开实施例中，上述为终端13提供无线通信功能的装置统称为接入网设备。
终端13的数量通常为多个，每一个接入网设备14所管理的小区内可以分布一个或多个终端13。终端13可以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他处理设备，以及各种形式的用户设备、移动台(Mobile Station，MS)等等。为方便描述，上面提到的设备统称为终端。接入网设备14与核心网设备之间通过某种空中技术相互通信，例如5G NR系统中的NG接口。接入网设备14与终端13之间通过某种空中技术互相通信，例如Uu接口。
终端13和终端13(例如车载设备与其它设备(如其它车载设备、手机、路侧单元(Road Side Unit，RSU)等))之间可以通过直连通信接口(如PC5接口)互相通信，相应地，该基于直连通信接口建立的通信链路可以称为直连链路或侧行链路(Sidelink，SL)。SL传输即为终端与终端之间通过侧行链路直接进行通信数据传输，不同于传统的蜂窝系统中通信数据通过接入网设备接收或者发送，SL传输具有时延短、开销小等特点，适合用于地理位置接近的两个终端(如车载设备和地理位置接近的其它周边设备)之间的通信。需要说明的是，在图3中，仅以V2X场景下的车对车通信为示例，SL技术可以应用于各种终端之间直接进行通信的场景。或者说，本申请中的终端是指任意一种利用SL技术通信的设备。本公开实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。本公开实施例描述的技术方案可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统。本公开实施例中的UE与终端表达同一含义，两者可以相互替换。
首先，对协作感知场景和混合定位场景进行介绍：
协作感知场景：通信感知是基站或终端发送通信信号对目标进行检测和估计，判断目标是否存在，并估计其速度、距离和来波方向角等信息。目标可以是人体或者物品，实现人体入侵/移动/跌倒等的检测、姿势识别，三维空间物品图像建立等功能。结合移动通信网络存在多个通信节点的特点，多个节点之间可以通信协作，借助多节点协作提升感知性能，实现基于多节点的协作感知。图2示出了协作感知场景的网络架构的示意图。其中，(a)上行链路发送参考信号示出了，第一终端22在上行链路发送参考信号，第二终端23和网络设备21对参考信号进行测量，对环境中的目标24进行感知，实现协作感知。(b)侧行链路发送参考信号示出了，第一终端22在侧行链路发送参考信号，第二终端23和网络设备21对参考信号进行测量，对环境中的目标24进行感知，实现协作感知。
混合定位场景：混合定位是基站和终端基于Uu接口和PC5接口对目标终端进行定位，目标终端发送参考信号，基站和终端通过测量参考信号对目标终端进行测量。图3示出了混合定位场景的网络架构的示意图。基站31和锚点终端33为目标车载终端32提供定位服务；锚点终端33通过PC5接口对目标车载终端32进行定位，基站31通过Uu接口对目标车载终端32进行定位。相似的，目标车载终端32发送的参考信号是在上行链路或侧行链路发送的。示例性的，在混合定位场景中使用的定位方式包括但不限于如下至少之一：上行链路到达时间差(Uplink-Time Difference Of Arrival，UL-TDOA)、多小区往返行程时间定位法(Multi-Round Trip Time，Multi-RTT)。
图4提供了本申请一个实施例提供的参考信号的配置方法的流程图，该方法由第一终端、第二终端和目标设备执行；该方法中的网络设备可以是接入网或核心网中的设备，网络设备包括第一网元和/或第二网元，第一网元是接入网设备，第二网元是核心网设备。该方法包括：
步骤210：发送设备向目标设备发送参考信号的配置信息；
在本实施例中，参考信号用于协作感知或混合定位。参考信号通过第一链路传输；目标设备是第一链路以外的设备。
在一些实施例中，第一链路是上行链路，参考信号是通过上行链路传输的；可选的，参考信号是第一终端向第一网元或第二网元传输的，第一链路是第一终端与第一网元之间的上行链路。相应的，目标设备是第一链路以外的设备，比如第二终端。发送设备向第二终端发送参考信号的配置信息，比如：第一终端通过侧行链路向第二终端发送参考信号的配置信息，或，第一网元或第二网元通过下行链路向第二终端发 送参考信号的配置信息。
在一些实施例中，第一链路是侧行链路，参考信号是通过侧行链路传输的；可选的，参考信号是第一终端向第二终端传输的，第一链路是第一终端和第二终端之间的侧行链路。相应的，目标设备是第一链路以外的设备，比如第一网元或第二网元。发送设备向第一网元或第二网元发送参考信号的配置信息，比如：第一终端或第二终端向第一网元或第二网元发送参考信号的配置信息。
示例性的，第一网元是接入网设备，比如：gNB。第二网元是核心网设备，比如：定位管理功能(Location Management Function，LMF)、接入和移动性管理功能(Access and Mobility Management Function，AMF)、感知控制网元(Sensing Function，SF)中的任意之一。
可以理解的，本申请中仅仅限制了目标设备是第一链路以外的设备；也就是说接收配置信息的设备不在第一链路上。而对配置信息的发送方(或称发送设备)没有进行限制，发送方通常位于第一链路上，可以是参考信号在第一链路上的发送方设备或接收方设备，当然配置信息的发送方也可以不在第一链路上，比如是LMF。
步骤220：目标设备接收参考信号的配置信息；
相应的，目标设备接收发送设备发送的参考信号的配置信息。基于参考信号的配置信息对参考信号进行测量，以实现协作感知或混合定位。
综上所述，本实施例提供的方法，通过向目标设备发送参考信号的配置信息，实现参考信号所在的第一链路以外的目标设备能够获知参考信号的配置信息，从而实现目标设备对参考信号进行测量，避免了目标设备无法对参考信号进行测量的情况，提高了协作感知场景或混合定位场景中参考信号的测量效果。
在本申请中至少包括第一链路是上行链路，或，第一链路是侧行链路两种场景。下文对两个场景分别进行介绍。

综上所述，本实施例提供的方法，通过向第二终端发送参考信号的配置信息，实现参考信号所在的上行链路以外的第二终端确定参考信号的配置信息，以利于第二终端对参考信号进行测量，避免了第二终端无法对参考信号进行测量的情况，提高了协作感知场景或混合定位场景中参考信号的测量效果。
