随着移动通信技术的不断发展，移动终端不再只是具有单一功能的通讯工具，而是集成了各种各样的应用功能。其中，终端的定位应用功能应用十分广泛。以工业物联网中的终端定位功能为例，终端定位的精准度成为工业物联网的一个关键指标。高精度的关键定位技术将广泛应用于典型的工业物联网应用场合。在相关的定位技术中，对终端进行定位时，能够满足3米的定位精度。但是，在工业物联网的诸多应用场合，要求对终端的定位精度为0.2米至1米。因此，存在终端的定位精度低的问题。

请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个用户设备110以及若干个基站120。
其中，用户设备110可以是指向用户提供语音和/或数据连通性的设备。用户设备110可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，用户设备110可以是物联网(Internet of Things，IoT)用户设备，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网用户设备的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程用户设备(remote terminal)、接入 用户设备(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment)。或者，终端110也可以是工业物联网(Industry Internet of Things，IIoT)设备，比如铲车、自动组装设备等。或者，用户设备110也可以是无人飞行器的设备。或者，用户设备110也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线用户设备。或者，用户设备110也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站120可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。
其中，基站120可以是4G系统中采用的演进型基站(eNB)。或者，基站120也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站120的具体实现方式不加以限定。
基站120和用户设备110之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标 准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，用户设备110之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
这里，上述用户设备可认为是下面实施例的终端设备。
在一些实施例中，上述无线通信系统还可以包含网络管理设备130。
若干个基站120分别与网络管理设备130相连。其中，网络管理设备130可以是无线通信系统中的核心网设备，比如，该网络管理设备130可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。或者，该网络管理设备130可以是定位管理功能(Location Management Function)实体。对于网络管理设备130的实现形态，本公开实施例不做限定。
为了方便对本公开任一实施例的理解，首先，对终端的定位场景进行说明。
在一种应用场景中，请参见图2，终端根据接收到三个或者三个以上基站(例如，基站1、基站2和基站3)发送的定位用途参考信号的时间与终端接收到参考基站发送的定位用途参考信号的时间的差值，来分别计算各基站与终端之间定位用途参考信号传输时延的相对差值。再根据该传输时延的相对差值和基站位置计算出终端的位置。这里，各个基站向终端发送 的定位用途参考信号可以是下行的定位参考信号(PRS，Positioning Reference Signal)。
在另一种应用场景中，请参见图3，终端向三个或者三个以上基站(例如，基站4、基站5和基站6)发送定位用途参考信号，各基站测量接收到该定位用途参考信号的时间与参考时间的差值，并上报给定位管理功能实体，定位管理功能实体根据各个时间差值和基站的位置计算出终端的位置。这里，终端向基站发送的信号可以是上行用于定位的探测参考信号(SRS，Sounding Reference Signal)。
新空口第16版(NR Rel-16，New Radio Release-16)中新定义了下行的定位参考信号(PRS)。下行的定位参考信号(PRS)在频域占用的资源是利用以下三个参数来配置的：1、DL-PRS-PointA，定义了某个载频上的频域参考点，比如，参考点可以是位于该载频上最低频的子载波的位置。2、DL-PRS-StartPRB，定义了以point A为参考点，定位参考信号(PRS)的带宽的起始物理资源块(PRB，Physical Resource Block)位置。3、DL-PRS-ResourceBandwidth，定义了定位参考信号(PRS)占用的带宽大小。带宽大小为4个物理资源块(PRB)的倍数，带宽最少可以包含24个物理资源块，最多可以包含272个物理资源块。根据上述三个参数，终端就能确定定位参考信号(PRS)的频域资源包含的物理资源块(PRB)的位置。
在一个实施例中，用于定位的参考信号都是通过一个天线端口(port)来发送或者接收的。由于一个天线端口(port)不能够同时发送或者接收多个用于定位的参考信号，只能以时分的方式发送或接收用于定位的参考信号，这样，会带来较大的时延。
在一个实施例中，在同一个载频上的所有定位参考信号(PRS)对应的上述三个参数都是一样的。且对于用于上行定位的探测参考信号(SRS)，也没有区分频域资源位置。这样，用于定位的参考信号的频域资源位置单一，频域资源占用的带宽较小，导致终端定位的精度较低。
如图4所示，本实施例中提供一种定位用途参考信号的资源配置方法，其中，应用于终端中，该方法包括：
步骤41，接收网络设备发送的多个定位用途参考信号的资源配置信息；
其中，资源配置信息，至少用于指示终端传输的定位用途参考信号资源的频域资源位置；至少两个定位用途参考信号的频域资源位于一个定位频率层的不同位置。
该终端可以是但不限于是手机、可穿戴设备、车载终端、路侧单元(RSU，Road Side Unit)、智能家居终端、物联网设备、工业物联网设备，(比如铲车)、传感设备和/或医疗设备等。
该网络设备可以是基站或者定位管理功能(LMF，Location Management Function)实体。
该基站为终端接入网络的接口设备。基站可以为各种类型的基站，例如，第三代移动通信(3G)网络的基站、第四代移动通信(4G)网络的基站、第五代移动通信(5G)网络的基站或其它演进型基站。
该定位用途参考信号可以是定位参考信号(PRS)或者用于定位的探测参考信号(SRS)。
这里，资源配置信息配置的资源可以是用于传输定位用途参考信号的时频域资源。
这里，用于传输定位用途的参考信号的定位频率层的频谱资源为授权频谱资源或者为非授权频谱资源。
在一个实施例中，终端在向网络设备发送定位请求后，接收网络设备针对该定位请求发送的多个定位用途参考信号资源的配置信息。这里，可以是终端启动终端上的定位功能的应用时，触发终端向网络设备发送该定位请求。例如，具有导航功能的应用被启动时，触发终端向网络设备发送该定位请求。还可以是接收到用户的定位操作指令时，触发终端向网络设 备发送该定位请求。例如，接收到用户针对具有定位功能的应用发送的位置更新的触控指令时，触发终端向网络设备发送该定位请求。
在一个实施例中，网络设备向终端发送定位请求，终端接收到该定位请求后，开始接收网络设备针对该定位请求发送的多个定位用途参考信号资源的配置信息。
在一个实施例中，当定位用途参考信号为下行的定位参考信号(PRS)，资源配置信息至少用于指示终端接收该下行的定位参考信号(PRS)的频域资源位置。
在一个实施例中，当定位用途参考信号为上行的用于定位的探测参考信号(SRS)，资源配置信息至少用于指示终端发送该上行的用于定位的探测参考信号(SRS)的频域资源位置。
在一个实施例中，资源配置信息可以指示终端在某个天线端口(port)上传输该多个定位用途参考信号。例如，配置信息可以指示终端在标识为“A”的天线端口上发送或者接收该多个定位用途参考信号。这里，终端可以是在某个天线端口上以时分的方式传输该多个定位用途参考信号。
在一个实施例中，资源配置信息可以指示终端在多个天线端口上传输该多个定位用途参考信号。例如，资源配置信息可以指示终端在标识为“A”的天线端口和标识为“B”的天线端口上传输该多个定位用途参考信号。这里，可以是在多个天线端口上同时传输该多个定位用途参考信号。例如，天线端口A、天线端口B和天线端口C分别同时传输第一定位用途参考信号、第二定位用途参考信号和第三定位用途参考信号。这里，同时传输多个定位用途参考信号，可以减小终端定位的时延，带给用户好的体验。
在一个实施例中，资源配置信息可以指示终端在某个天线面板(panel)上传输该多个定位用途参考信号。这里，一个天线面板上可以设置有多个天线端口。例如，资源配置信息可以指示终端在标识为“C”的天线面板上传输该多个定位用途参考信号。则终端可以在标识为“C”的天线面板上的 多个天线端口上传输该多个定位用途参考信号。这里，可以是在标识为“C”的天线面板上的部分天线端口上传输该多个定位用途参考信号。在一个实施例中，当多个定位用途参考信号的传输波束相同时，终端可以在标识为“C”的天线面板上同时传输该多个定位用途参考信号；当多个定位用途参考信号的传输波束不同时，终端可以在标识为“C”的天线面板上以时分方式传输该多个定位用途参考信号。
在一个实施例中，资源配置信息可以指示终端在多个天线面板(panel)上传输该多个定位用途参考信号。这里，一个天线面板上可以设置有多个天线端口。资源配置信息可以指示终端在标识为“C”和标识为“D”的天线面板上传输该多个定位用途参考信号。则终端可以在标识为“C”和标识为“D”的天线面板上的多个天线端口上传输该多个定位用途参考信号。这里，标识为“C”的天线面板上和标识为“D”的天线面板上可以同时传输波束不同的定位用途参考信号。
在一个实施例中，资源配置信息可以携带终端传输定位用途参考信号的天线面板和/或天线端口的索引信息。这样，终端就可以在索引信息指示的天线面板和/或天线端口上传输定位用途参考信号。例如，第一天线面板的索引信息为“001”，第二天线面板的索引信息为“011”，则在终端确定资源配置信息中索引信息对应的信息域取值为“001”时，确定传输定位用途参考信号的天线面板为第一天线面板。在终端确定资源配置信息中索引信息对应的信息域取值为“011”时，确定传输定位用途参考信号的天线面板为第二天线面板。再比如，第一天线端口的索引信息为“100”，第二天线端口的索引信息为“110”，则在终端确定资源配置信息中索引信息对应的信息域取值为“100”时，确定传输定位用途参考信号的天线端口为第一天线端口。在终端确定资源配置信息中索引信息对应的信息域取值为“110”时，确定传输定位用途参考信号的天线端口为第二天线端口。
在一个实施例中，资源配置信息可以携带终端传输定位用途参考信号 的天线面板和/或天线端口的索引信息。这样，终端就可以在索引信息指示的天线面板和/或天线端口上传输定位用途参考信号。例如，天线面板的索引信息为天线面板传输过的参考信号或参考信号集合的标识，天线端口的索引信息为天线端口传输过的参考信号或参考信号集合的标识。如此，终端可以根据天线端口传输过的参考信号或参考信号集合的标识确定传输定位用途参考信号的天线面板和/或天线端口的索引信息。
在一个实施例中，资源配置信息中可以包含准共站址(QCL，Quasi co-location)信息，终端可以在准共站址(QCL)指示的波束上传输定位用途参考信号。这里，准共站址(QCL)指示的波束可以是上一时间段或上一时刻传输以下之一信号的波束：同步信号块(SSB，Synchronization Signal Block)、信道状态信息参考信号(CSI-RS，channel state information reference signal)、定位参考信号(PRS)或探测参考信号(SRS)。
在一个实施中，可以是至少两个定位用途参考信号中的部分定位用途参考信号的频域资源位于一个定位频率层(Positioning frequency layer)的不同位置。例如，共有4个定位用途参考信号，分别为第一定位用途参考信号、第二定位用途参考信号、第三定位用途参考信号和第四定位用途参考信号。其中，第一定位用途参考信号和第四定位用途参考信号的频域资源位置相同，第一定位用途参考信号与第二定位用途参考信号、第三定位用途参考信号的频域资源位置不同。这里，定位频率层上的频域资源可以是专用于传输定位用途参考信号的频谱资源的集合。该频谱资源可以是授权频谱资源，也可以是非授权频谱资源。例如，当需要发送上行用于定位的探测参考信号(SRS)或者需要发送下行定位参考信号(PRS)时，用到的频域资源就是该定位频率层所包含的频域资源。
在一个实施例中，至少两个定位用途参考信号的频域资源位于一个定位频率层的不同位置，包括：至少两个定位用途参考信号的物理资源块PRB的频域起始位置不同；和/或，至少两个定位用途参考信号资源的带宽不同。
在一个实施例中，频域资源位于一个定位频率层的不同位置可以是至少两个定位用途参考信号的物理资源块(PRB)的频域起始位置不同。例如，第一位置为以第1个物理资源块为起始位置的位置，第二位置为以第8个物理资源块为起始位置的位置，则第一位置不同于第二位置。
在一个实施例中，频域资源位于一个定位频率层的不同位置可以是至少两个定位用途参考信号资源的带宽不同。例如，第一定位用途参考信号在定位频率层占用的带宽是1M，第二定位用途参考信号在定位频率层占用的带宽为2M，则第一定位用途参考信号和第二定位用途参考信号位于一个定位频率层的不同位置。
在一个实施例中，频域资源位于一个定位频率层的不同位置可以是至少两个定位用途参考信号的物理资源块(PRB)的频域起始位置和资源的带宽均不同。
在一个实施例中，频域资源位于一个定位频率层的不同位置可以是至少两个定位用途参考信号的频域资源完全不重叠。例如，第一定位用途参考信号在定位频率层的物理资源块(PRB)的频域起始位置为第1个物理资源块(PRB)，对应占用的带宽为12个物理资源块(PRB)，即第一定位用途参考信号占用的物理资源块(PRB)为第1至第12个物理资源块(PRB)。第二定位用途参考信号在定位频率层的物理资源块(PRB)的频域起始位置为第16个物理资源块(PRB)，对应占用的带宽为12个物理资源块(PRB)，即第二定位用途参考信号占用的物理资源块(PRB)为第16至第28个物理资源块(PRB)。则第一定位用途参考信号与第二定位用途参考信号位于一个定位频率层的不同位置。
在一个实施例中，资源配置信息还可以包括指示终端进行定位用途参考信号的测量结果上报的方式的信息。例如，资源配置信息携带指示终端利用不同的测量报告分别上报至少两个定位用途参考信号的测量结果的信息。如此，终端会基于该资源配置信息，利用不同的测量报告分别上报至 少两个定位用途参考信号的测量结果。再例如，资源配置信息携带指示终端利用一个测量报告上报至少两个定位用途参考信号的测量结果的信息。如此，终端会基于该资源配置信息，利用一个测量报告上报至少两个定位用途参考信号的测量结果的信息。
这里，由于至少两个定位用途参考信号的频域资源位于一个定位频率层的不同位置，在利用定位用途参考信号的信号测量结果进行终端的定位时，可以综合不同位置的频域资源传输的定位用途参考信号的信号测量结果确定终端的位置，相较于仅利用单一位置的频域资源传输的定位用途参考信号的信号测量结果确定终端的位置，能够获得更加准确的定位结果，终端的定位精度会更高。
如图5所示，本实施例中提供一种定位用途参考信号的资源配置方法，其中，步骤41中，接收网络设备发送的多个定位用途参考信号的资源配置信息，包括：

在一个实施例中，一个天线面板(panel)在同一时刻只能指向一个波束方向。每个天线面板(panel)对应设置有一个或多个天线端口(port)。
在一个实施例中，可以是根据终端的默认配置信息确定用于传输至少两个定位用途参考信号的终端侧天线端口和/或天线面板。
在一个实施例中，可以是根据资源配置信息确定用于传输至少两个定位用途参考信号的天线端口和/或天线面板。例如，资源配置信息携带了传输至少两个定位用途参考信号的天线端口和/或天线面板的标识信息。终端可以根据该标识信息确定用于传输至少两个定位用途参考信号的天线端口和/或天线面板。这里，天线面板的标识可以是天线面板身份标识(Panel ID)，不同天线面板对应分配不同的天线面板身份标识(Panel ID)。这里，天线端口的标识可以是天线端口身份标识(Port ID)，不同天线端口对应分配不同的天线端口身份标识(Port ID)。这里，天线面板的索引信息还可以是天线面板传输过的参考信号或参考信号集合的标识；天线端口的索引信息还可以是天线端口传输过的参考信号或参考信号集合的标识。

如图7所示，本实施例中提供一种定位用途参考信号的资源配置方法，步骤61中，确定用于传输至少两个定位用途参考信号的天线端口和/或天线面板，包括：
步骤71，根据资源配置信息指示的至少两个定位用途参考信号的第一天线端口索引和/或第一天线面板索引，确定用于传输至少两个定位用途参考信号的天线端口和/或天线面板。
在一个实施例中，第一天线端口索引可以是天线端口身份标识(Port ID)，不同的第一天线端口对应分配不同的天线端口身份标识(Port ID)。第一天线端口索引还可以是第一天线端口传输过的参考信号或参考信号集 合的标识。这里，第一天线端口索引指示的是终端侧的天线端口索引。
在一个实施例中，第一天线面板索引可以是天线面板身份标识(panel ID)，不同的天线面板对应分配不同的天线面板身份标识(panel ID)。第一天线面板索引还可以是第一天线面板传输过的参考信号或参考信号集合的标识。这里，第一天线面板索引指示的是终端侧的天线面板索引。
在一个实施例中，资源配置信息还用于指示传输至少两个所述定位用途参考信号的第一发送接收点(TRP)索引和/或第一物理小区标识。
在一个实施例中，每个基站(或者物理小区)可以设置有多个发送接收点(TRP)。每个发送接入点(TRP)可以设置有一个或多个天线面板(panel)。
在一个实施例中，每个基站也可以只设置一个发送接收点(TRP)，该发送接收点(TRP)可以设置有多个天线面板(panel)。
在一个实施例中，基站可以使用多个天线面板(panel)同时向同一个终端发送定位用途参考信号。多个天线面板(panel)可以属于同一个发送接收点(TRP)或不同的发送接收点(TRP)。
在一个实施例中，资源配置信息指示的传输至少两个所述定位用途参考信号的第一发送接收点(TRP)索引不同，即指示终端在不同频域资源上与不同的第一发送接收点(TRP)传输定位用途参考信号。
在一个实施例中，资源配置信息指示的传输至少两个所述定位用途参考信号的第一发送接收点(TRP)索引相同且第一物理小区标识不同，即指示终端在不同频域资源上与不同物理小区的第一发送接收点(TRP)传输定位用途参考信号。
在一个实施例中，资源配置信息指示的传输至少两个所述定位用途参考信号的第一物理小区标识不同，即指示终端在不同频域资源上与不同物理小区传输定位用途参考信号。
在一个实施例中，资源配置信息指示的传输至少两个所述定位用途参 考信号的第一发送接收点(TRP)索引相同，即指示终端在不同频域资源上与相同的第一发送接收点(TRP)传输定位用途参考信号。
在一个实施例中，资源配置信息指示的传输至少两个所述定位用途参考信号的第一发送接收点(TRP)索引相同且第一物理小区标识相同，即指示终端在不同频域资源上与同一物理小区的同一第一发送接收点(TRP)传输定位用途参考信号。
在一个实施例中，资源配置信息指示的传输至少两个所述定位用途参考信号的第一物理小区标识相同，即指示终端在不同频域资源上与同一物理小区传输定位用途参考信号。
这里，根据第一天线端口索引、第一天线面板索引确定终端侧传输某个定位用途参考信号的天线端口和/或天线面板；根据第一发送接收点(TRP)索引和第一物理小区标识就确定网络侧传输某个定位用途参考信号的发送接收点(TRP)和/或物理小区。
在一个实施例中，资源配置信息配置的多个定位用途参考信号的终端侧天线端口不同，但是配置的发送接收点(TRP)索引和物理小区标识相同，则是用终端侧的不同天线端口与相同发送接收点(TRP)传输不同定位用途参考信号，即终端可以使用不同天线端口在不同频域资源上与一个TRP或一个小区传输不同的定位用途参考信号。这样，可以增加定位用途参考信号的传输带宽，提高精确度。
在一个实施例中，资源配置信息配置的多个定位用途参考信号的终端侧天线端口不同，而且配置的发送接收点(TRP)索引和物理小区标识不同，则是用终端侧的不同天线端口与不同发送接收点(TRP)传输不同定位用途参考信号。这样，如果不同定位用途参考信号的传输时间相同的话，即终端可以使用不同天线端口在不同频域资源上与多个TRP或多个小区同时传输不同的定位用途参考信号，则可以减少时延。
在一个实施例中，资源配置信息包含：准共站址(QCL)信息；准共 站址(QCL)信息，用于分别指示终端传输至少两个定位用途参考信号中各个定位用途参考信号的波束信息；
其中，准共站址QCL信息，包括波束信息参考信号索引和以下一种或者多种：传输波束信息参考信号的第二天线端口标识、传输波束信息参考信号的第二天线面板标识、传输波束信息参考信号的第二发送接收点TRP标识、传输波束信息参考信号的第二物理小区标识。
在一个实施例中，波束信息参考信号可以包括以下之一：同步信号块(SSB，Synchronization Signal Block)、信道状态信息参考信号(CSI-RS，channel state information reference signal)、定位参考信号(PRS)或探测参考信号(SRS)。
在一个实施例中，当准共站址(QCL)指示的是终端的下行接收波束时，基站可以告知终端使用接收参考信号身份标识(ID)对应的参考信号的接收波束来接收下行发送的信号，或使用发送参考信号身份标识(ID)对应的参考信号的发送波束对应的接收波束来接收下行发送的信号；当指示的是终端上行发送波束时，基站可以告知终端使用发送参考信号身份标识(ID)对应的参考信号的发送波束来发送上行发送信号，或使用接收参考信号身份标识(ID)对应的参考信号的接收波束对应的发送波束来发送上行发送信号。
在一个实施例中，由于不同的天线端口或天线面板或发送接收点或物理小区中的波束信息参考信号身份标识(ID)可能一样，所以准共站址(QCL)除了给出波束信息参考信号身份标识(ID)，还会指示该波束信息参考信号对应的天线端口、天线面板、发送接收点、物理小区的身份标识(ID)中的至少一种。这样，使得波束信息的指示更加准确。
在一个实施例中，以定位参考信号为例，配置信息指示了发送接收点为TRP1，则是说明这个定位参考信号是发送接收点TRP1发送给终端的。
而该定位参考信号的准共站址(QCL)信息指示了同步信号块为SSB#0 和物理小区为cell#1，则是表示配置终端使用接收物理小区cell#1的同步信号块SSB#0时的接收波束来接收发送接入点TRP1的定位参考信号。
在一个实施例中，定位用途参考信号为上行用于定位的探测参考信号(SRS)时，资源配置信息，还用于指示每个第一天线端口标识的发送功率。
在一个实施例中，不同的探测参考信号(SRS)的用于路损(pathloss)估计的参考信号不同，可以是根据用于路损(pathloss)估计的参考信号的接收功率来确定探测参考信号(SRS)的发送功率。
在一个实施例中，比如终端有2个天线端口(port)，每个天线端口(port)都发送定位用途参考信号，则最大可以分别使用该终端最大发送功率的一半来发送。
在一个实施例中，终端使用一个天线端口(port)发送定位用途参考信号，则最大可以使用该终端的最大发送功率的一半来发送定位用途参考信号或者使用该终端的最大发送功率发送定位用途参考信号或者是使用该天线端口(port)能支持的最大发送功率发送定位用途参考信号。这里，具体采用上述哪种发送功率发送定位用途参考信号可以根据默认配置或资源配置信息的指示确定。

在一个实施例中，资源配置信息可以指示终端在某个天线面板(panel)上传输该多个定位用途参考信号。这里，一个天线面板上可以设置有多个天线端口。例如，资源配置信息可以指示终端在标识为“C”的天线面板上传输该多个定位用途参考信号。则终端可以在标识为“C”的天线面板上的多个天线端口上传输该多个定位用途参考信号。这里，可以是在标识为“C”的天线面板上的部分天线端口上传输该多个定位用途参考信号。在一个实施例中，当多个定位用途参考信号的传输波束相同时，终端可以在标识为“C”的天线面板上使用不同的天线端口同时传输该多个定位用途参考信号；当多个定位用途参考信号的传输波束不同时，终端可以在标识为“C”的天线面板上以时分方式传输该多个定位用途参考信号。
在一个实施例中，资源配置信息可以指示终端在多个天线面板(panel)上传输该多个定位用途参考信号。这里，一个天线面板上可以设置有多个天线端口。资源配置信息可以指示终端在标识为“C”和标识为“D”的天线面板上传输该多个定位用途参考信号。则终端可以在标识为“C”和标识为“D”的天线面板上的多个天线端口上传输该多个定位用途参考信号。这里，标识为“C”的天线面板上和标识为“D”的天线面板上可以同时传输波束不同的定位用途参考信号。
在一个实施例中，资源配置信息可以携带终端传输定位用途参考信号的天线面板和/或天线端口的索引信息。这样，终端就可以在索引信息指示的天线面板和/或天线端口上传输定位用途参考信号。例如，第一天线面板的索引信息为“001”，第二天线面板的索引信息为“011”，则在终端确定资源配置信息中索引信息对应的信息域取值为“001”时，确定传输定位用途参考信号的天线面板为第一天线面板。在终端确定资源配置信息中索引信息对应的信息域取值为“011”时，确定传输定位用途参考信号的天线面板为第二天线面板。再比如，第一天线端口的索引信息为“100”，第二天线端口的索引信息为“110”，则在终端确定资源配置信息中索引信息对 应的信息域取值为“100”时，确定传输定位用途参考信号的天线端口为第一天线端口。在终端确定资源配置信息中索引信息对应的信息域取值为“110”时，确定传输定位用途参考信号的天线端口为第二天线端口。

在一个实施例中，资源配置信息指示的传输至少两个所述定位用途参考信号的第一物理小区标识不同，即指示终端在不同频域资源上与不同物理小区传输定位用途参考信号。
在一个实施例中，资源配置信息指示的传输至少两个所述定位用途参考信号的第一发送接收点(TRP)索引相同，即指示终端在不同频域资源上与相同的第一发送接收点(TRP)传输定位用途参考信号。
在一个实施例中，资源配置信息指示的传输至少两个所述定位用途参考信号的第一发送接收点(TRP)索引相同且第一物理小区标识相同，即指示终端在不同频域资源上与同一物理小区的同一第一发送接收点(TRP)传输定位用途参考信号。
在一个实施例中，资源配置信息指示的传输至少两个所述定位用途参考信号的第一物理小区标识相同，即指示终端在不同频域资源上与同一物理小区传输定位用途参考信号。
这里，根据第一天线端口索引、第一天线面板索引确定终端侧传输某个定位用途参考信号的天线端口和/或天线面板；根据第一发送接收点(TRP)索引和第一物理小区标识就可以确定网络侧传输某个定位用途参考信号的发送接收点(TRP)和/或物理小区。
在一个实施例中，资源配置信息配置的多个定位用途参考信号的终端侧天线端口不同，但是配置的发送接收点(TRP)索引和物理小区标识相同，则是用终端侧不同天线端口与相同发送接收点(TRP)传输不同定位用途参考信号，即终端可以使用不同天线端口在不同频域资源上与一个发送接收点(TRP)或一个小区传输不同的定位用途参考信号。这样，可以增加定位用途参考信号的传输带宽，提高精确度。
在一个实施例中，资源配置信息配置的多个定位用途参考信号的终端侧天线端口不同，而且配置的发送接收点(TRP)索引和物理小区标识不同，则是用终端侧不同天线端口与不同发送接收点(TRP)传输不同定位用途参考信号。这样，如果不同定位用途参考信号的传输时间相同的话，即终端可以使用不同天线端口在不同频域资源上与多个发送接收点(TRP)或多个小区同时传输不同的定位用途参考信号，如此，可以减少时延。
在一个实施例中，资源配置信息包含：准共站址(QCL)信息；准共站址(QCL)信息，用于分别指示终端传输至少两个定位用途参考信号中各个定位用途参考信号的波束信息；
其中，准共站址QCL信息，包括波束信息参考信号索引和以下一种或者多种：传输波束信息参考信号的第二天线端口标识、传输波束信息参考信号的第二天线面板标识、传输波束信息参考信号的第二发送接收点TRP标识、传输波束信息参考信号的第二物理小区标识。
在一个实施例中，波束信息参考信号可以包括以下之一：同步信号块(SSB，Synchronization Signal Block)、信道状态信息参考信号(CSI-RS，channel state information reference signal)、定位参考信号(PRS)或探测参考信号(SRS)。
在一个实施例中，当准共站址(QCL)指示的是终端的下行接收波束时，基站可以告知终端使用接收参考信号身份标识(ID)对应的参考信号的接收波束来接收下行发送的信号，或使用发送参考信号身份标识(ID) 对应的参考信号的发送波束对应的接收波束来接收下行发送的信号；当指示的是终端上行发送波束时，基站可以告知终端使用发送参考信号身份标识(ID)对应的参考信号发送波束来发送上行发送信号，或使用接收参考信号身份标识(ID)对应的参考信号的接收波束对应的发送波束来发送上行发送信号。
在一个实施例中，由于不同的天线端口或天线面板或发送接收点(TRP)或物理小区中的波束信息参考信号身份标识(ID)可能一样，所以准共站址(QCL)除了给出波束信息参考信号身份标识(ID)，还会指示该波束信息参考信号对应的天线端口、天线面板、发送接收点(TRP)、物理小区的身份标识(ID)中的至少一种。这样，使得波束信息的指示更加准确。
在一个实施例中，以定位参考信号为例，配置信息指示了发送接收点为TRP1，则是说明这个定位参考信号是发送接收点TRP1发送给终端的。
而该定位参考信号的准共站址(QCL)信息指示了同步信号块为SSB#0和物理小区为cell#1，则是表示配置终端使用接收物理小区cell#1的同步信号块SSB#0时的接收波束来接收发送接入点TRP1的定位参考信号。
在一个实施例中，定位用途参考信号为上行用于定位的探测参考信号(SRS)时，资源配置信息，还用于指示每个第一天线端口标识的发送功率。
在一个实施例中，不同的探测参考信号(SRS)的用于路损(pathloss)估计的参考信号不同，可以是根据用于路损(pathloss)估计的参考信号的接收功率来确定探测参考信号(SRS)的发送功率。
在一个实施例中，比如终端有2个天线端口(port)，每个天线端口(port)都发送定位用途参考信号，则最大可以分别使用该终端最大发送功率的一半来发送。
在一个实施例中，终端使用一个天线端口(port)发送定位用途参考信号，则最大可以使用该终端的最大发送功率的一半来发送定位用途参考信号或者使用该终端的最大发送功率发送定位用途参考信号或者是使用该天 线端口(port)能支持的最大发送功率发送定位用途参考信号。这里，具体采用上述哪种发送功率发送定位用途参考信号可以根据默认配置或资源配置信息的指示确定。
如图11所示，本实施例中提供一种定位用途参考信号的资源配置方法，该还包括：
步骤111，接收终端发送的利用不同的测量报告分别上报的至少两个定位用途参考信号的测量结果；或者，接收终端发送的利用一个测量报告上报的至少两个定位用途参考信号的测量结果。
在一个实施例中，资源配置信息还可以包括指示终端进行定位用途参考信号的测量结果上报的方式的信息。例如，携带指示终端利用不同的测量报告分别上报至少两个定位用途参考信号的测量结果的信息。如此，终端会基于该资源配置信息，响应于需要向网络设备上报至少两个定位用途参考信号的测量结果，利用不同的测量报告分别上报至少两个定位用途参考信号的测量结果。再例如，携带指示终端利用一个测量报告上报至少两个定位用途参考信号的测量结果的信息。如此，终端会基于该资源配置信息，响应于需要向网络设备上报至少两个定位用途参考信号的测量结果，利用一个测量报告上报至少两个定位用途参考信号的测量结果的信息。
