Description

一种角度定位的方法、装置以及设备 技术领域
本申请实施例涉及通信领域，尤其涉及一种角度定位的方法、装置以及设备。
背景技术
随着通信技术的发展，通信技术的应用越来越广泛，而通信技术与人们的生活息息相关。近年来，定位技术受到了越来越多的关注，从而推动了定位技术的研究与发展，而利用角度定位就是一种常用的定位技术。为了获取角度，基站通过每根天线上分别接收的信号之间的相位差，结合天线之间的距离与信号波长就可以获取信号的角度。然而在现有的高频系统中，不同天线的信号被合成到一个接收信号中，无法直接由相位差的方式对角度进行获取。
目前，在高频多载波通信系统中，采用波束扫描的方式获取角度可以解决无法由相位差的方式获取角度的问题。波束扫描需要基站接收终端设备发送的波束上报结果，例如，波束上报结果包括参考信号接收功率(RSRP，reference signal receiving power)以及信号与干扰加噪声比(SINR，signal to interference plus noise ratio)，然后对波束上报结果基于基站算法获取角度信息。另外，还可以通过波束功率获取角度，终端设备通过波束向基站发送至少一个波束对应的接收信号功率，基站根据多个接收信号功率的相对大小获取角度。
然而在高频系统的混合架构下，波束的指向不仅与每个面板的权值有关，还与波束对应的子载波频率有关，当某频率下的波束指向与子载波频率指向不同时，会出现波束倾斜现象。因此在带宽较大的情况下，波束倾斜现象会导致波束指向产生偏移，造成角度获取的准确度低，从而角度定位的准确度低。

为了更好地理解本申请实施例公开的一种角度定位的方法、装置以及设备，下面先对本发明实施例使用的系统架构进行描述。请参阅图1，图1为本申请实施例中多载波通信系统的系统架构示意图。
本申请实施例可以应用于终端设备长期演进(long term evolution,LTE)系统、第五代(5th generation，5G)移动通信系统或者下一代的通信系统，如6G、设备到设备(device to device，D2D)通信系统、物联网通信系统、车联网通信系统。下面将以多载波通信系统的系统架构为例进行介绍。如图1所示，在此系统架构中，该网络设备与终端设备，组成一个通信系统，其中，终端设备包括终端设备1至终端设备6。在该多载波通信系统中，终端设备1至终端设备6可以发送上行数据给网络设备，网络设备接收该终端设备1至终端设备6发送的上行数据。另外，终端设备4至终端设备6也可以组成一个通信系统。在该通信系统中，网络设备可以发送下行数据给终端设备1、终端设备2、终端设备3和终端设备5；终端设备5也可以发送下行信息给终端设备4和终端设备6。多载波通信系统中包括通信系统中的上行(终端设备到网络设备)通信和下行(接入网络设备到终端设备)通信，在物理层，上行通信包括上行物理信道和上行信号的传输。其中上行物理信道包括但不限于：随机接入信道(random access channel，PRACH)，上行控制信道(physical uplink control channel，PUCCH)以及上行数据信道(physical uplink shared channel，PUSCH)。 上行信号包括但不限于：信道探测信号(sounding reference signal，SRS)，上行控制信道解调参考信号(PUCCH de-modulation reference signal，PUCCH-DMRS)，上行数据信道解调参考信号，上行相位噪声跟踪信号(phase noise tracking reference signal，PTRS)以及上行定位信号。下行通信包括下行物理信道以及下行信号的传输，其中下行物理信道包括但不限于：广播信道(physical broadcast channel，PBCH)，下行控制信道(physical downlink control channel，PDCCH)以及下行数据信道(physical downlink shared channel，PDSCH)。下行信号包括但不限于：主同步信号(primary synchronization signal，PSS)，辅同步信号(secondary synchronization signal，SSS)，下行控制信道解调参考信号，下行数据信道解调参考信号，相位噪声跟踪信号，信道状态信息参考信号(channel status information reference signal，CSI-RS)以及定位参考信号(Positioning RS)。
目前应用于多载波通信系统的角度定位技术示意图如图2所示，网络设备通过对接收信号进行测量(上行)，对发送信号进行测量反馈(下行)，然后获取到网络设备和终端设备之间的位置角度关系，通常位置角度关系为离开角，如图2所示，网络设备A，网络设备B以及网络设备C对同一个终端设备可以获取到离开角1、离开角2以及离开角3，进而通过多组离开角对终端设备进行定位。可以理解的是，在实际应用中，角度定位技术还可以与时延、场强等定位技术结合，具体通过时延、场强获取用户位置的方法本申请不做限定。
进一步地，为了更好地理解本申请实施例公开的一种角度定位的方法，下面将对本发明实施例使用的角度定位系统架构进行描述。请参阅图3，图3为本申请实施例中角度定位系统的系统架构示意图。
在图3所示的角度定位系统中，至少包括一个网络设备以及网络设备所服务的一个或多个终端设备。其中网络设备包括但不限于：基站，定位服务中心以及传输点，而终端设备在发明实施例中主要为需定位的终端设备。
如图3所示，终端设备与定位服务中心之间的数据交互通过LTE定位协议(long term evolution positioning protocol，LPP)或NR定位协议(new radio positioning protocol，NRPP)实现，而基站与定位服务中心之间的数据交互通过LTE定位协议a(long term evolution positioning protocol a，LPPa)或NR定位协议a(new radio positioning protocol a，NRPPa)实现。
应理解的是，当网络设备为定位服务中心时，定位服务中心还包括位置管理功能以及演进服务移动位置中心中的至少一个，网络设备主要用于收集浏览器/服务器结构(browser/server，B/S)以及终端设备的测量信息和位置信息，并且同时负责将终端设备所上报的测量结果进行位置解算，然后确定终端设备的位置。
可以理解的是，当网络设备为基站时，网络设备可以是演进型基站(eNB，evolved Node B)、下一代基站(gNB，next generation Node B)、下一代e-NB(ng-eNB，next generation-evolved Node B)、传输接收点TRP或者是其他的设备，而当网络设备为eNB或gNB时，网络设备具体可以为服务小区基站或为邻区基站。
其中，eNB是LTE(4G)中终端设备和演进分组核心网(Evolved Packet Core，EPC)之 间的桥梁，eNB之间通过X2接口进行连接，主要功能有无线资源管理、IP头压缩及用户数据流加密、终端设备附着时的MME选择、路由用户面数据至S-GW、寻呼消息的组织和发送、广播消息的组织和发送、以移动性或调度为目的的测量及测量报告配置等。
gNB是为终端设备提供新无线(new radio,NR)用户面和控制面协议的基站，其可以通过NG接口连接到5G核心网(5GC)。
ng-eNB是为终端设备提供E-UTRA用户面和控制面协议的基站，其通过NG接口连接到5GC。
终端设备1至终端设备6，可以是一种向用户提供语音和/或数据连通性的设备，或，设置于该设备内的芯片，例如，具有无线连接功允许的手持式设备、车载设备等。目前，一些终端设备的举例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)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。
图4示出了在低频系统下的全数字架构收发机，在低频段的多天线系统中，每根接收天线的收到的信号都会通过模数转换转器换为数字信号，然后进行基带的信号处理。如图4所示，由于每个天线接受到的信号都通过模数转换转换到数字域进行存储，基带可以获取到每个天线上的完整信号信息。
进一步地，请参阅图5，图5为本申请实施例中基于高频系统的混合架构收发机的架构示意图，在高频系统中，为了对抗路径损耗，高频系统需要更多的天线提供更高的天线增益，因此高频系统的天线数量通常较多，通常天线数量达到几十甚至几百，如果将每个收发天线的信号转到数字域进行单独处理，则需要大量的模数/数模转换设备。因此，为了控制成本以及功耗，在高频系统架构中，通常将多个天线的接收信号在模拟域进行合成，然后转到数字域。这样能够节约一定的成本。相比低频的全数字架构，这种架构在模拟域进行了一定的预处理，被称为混合架构。如图5所示，混合架构的模拟域在一个时刻只能使用一个权值接收信号，模拟域合成时的权值一旦固定，模拟域的接收信号的也就固定了，随后信号从模拟域转到数字域之后可以进行各种数字信号处理，但是模拟域本身的处理已经固定，无法重新修改。一种典型的模拟域处理为通过阵列上的模拟权值将阵列的功率增益方向进行调整，也就是常说的模拟波束，在同一个时刻，一个模拟面板，也就是图5中所示子阵只能有一个权值，即一个确定波束方向。与低频的数字架构相比，高频系统每个面板的输出已经是经过了模拟域的加权合成的，该合成时不可逆的，所以混合架构中基带信号是每个天线的接收信号以子阵为单位进行不可逆的模拟滤波后的结果，因此每个天线单元上的信号不再是能完全恢复的。
因此，请参阅图6，图6为本申请实施例中基于高频系统的波束指向示意图，高频系统中混合架构收发机中，波束的指向不仅与每个阵子的权值有关，还与对应子载波的频率 有关。如果不考虑实际频率对波束指向的影响，就会造成实际中某个频率下的波束指向与载波频率的波束指向不同，这就是波束倾斜现象。该现象会导致离开角度(angle of department，AOD)估计性能恶化。如图6所示，其中fc代表载波频率下的波束指向，fmax代表系统中最大频率的波束指向，fmin代表系统中最小频率的波束指向，从图中可以发现这三个波束指向有明显的差别。并且当fc越大时，带宽越大，fmax以及fmin相较于中心频点的波束指向偏移越大。根据图2所示的角度定位示意图，在高频系统中，由于AOD估计性能恶化，从而导致对终端设备的角度定位的准确度低。
为了便于理解，这里对本申请实施例涉及到的一些术语或概念进行解释。
波束(beam)，是一种通信资源。波束可以是宽波束，还可以是窄波束或者其他类型波束。波束成形技术可以具体为数字波束成形技术，模拟波束成形技术或者混合数字/模拟波束成形技术。而不同的波束可以认为是不同的资源，通过不同的波束可以发送相同的信息或者不同的信息。可选地，可以将具有相同或者类似的通信特征的多个波束视为是一个波束，而一个波束内可以包括一个或多个天线端口，用于传输数据信道，控制信道和探测信号等，例如，发射波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度的分布，接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。可以理解的是，形成一个波束的一个或多个天线端口也可以看作是一个天线端口集，波束在协议中的体现还是可以空域滤波器(spatial filter)。
天线面板(panel)，无线通信的信号需要由天线进行接收和发送，多个天线单元(antenna element)可以集成在一个panel上，一个射频链路也可以驱动一个或多个天线单元。在本申请实施例中，终端设备可以包括多个天线面板，每个天线面板包括一个或者多个波束。网络设备也可以包括多个天线面板，每个天线面板包括一个或者多个波束。天线面板又可表示为天线阵列(antenna array)或者天线子阵列(antenna subarray)。一个天线面板可以包括一个或多个天线阵列/子阵列。一个天线面板可以有一个或多个晶振(oscillator)控制。射频链路又可以称为接收通道，发送通道以及接收机支路(receiver branch)。一个天线面板可以由一个射频链路驱动，也可以由多个射频链路驱动，因此本申请实施例中的天线面板也可以替换为射频链路或者驱动一个天线面板的多个射频链路或者由一个晶振控制的一个或多个射频链路。
波束辐射模式，指一个波束在不同水平、垂直方向上的波束增益，请参阅图7，如图7所示，图中有6个波束的在水平截面的辐射模式，即为竖直俯仰角0度对应平面的辐射模式。如图7所示，(1)波束的3db带宽(2)第一零值带宽(3)主峰至第一旁瓣距离(4)第一旁瓣/主瓣(5)零点位置。方向图通常都有两个瓣，或，多个瓣，其中辐射强度最大的瓣称为主瓣，其余的瓣称为副瓣或旁瓣，与主瓣相反方向上的旁瓣叫后瓣。在主瓣最大辐射方向两侧，辐射强度降低3dB，即功率密度降低一半的两点间的夹角定义为波瓣宽度，还被称为波束宽度或主瓣宽度或半功率角(half power beam width，HPBW)。可以理解的是，在实际应用中，波束在其他平面也可以通过类似方法表示，例如水平扫描角的某一个角度对应的垂直截面。
带宽，在5G系统中，终端设备的带宽可以动态的变化。终端设备的业务量较大时， 5G系统可以给终端设备配置一个大带宽，终端设备的业务量较小时，5G系统则给终端设备配置一个小带宽，即满足终端设备基本的通信需求。终端设备在对应的带宽部分(bandwidth part，BWP)内只需要采用对应BWP的中心频点以及采样率即可完成基本的通信需求。而且，每个BWP不仅是频点和带宽不一样，每个BWP还可以对应不同的配置，不同的配置用于适应不同的业务。
本实施例中，终端设备需要先从网络设备接收配置信息，然后终端设备再接收参考信号，进一步的终端设备根据接收到的配置信息对参考信息进行测量从而获取到测量结果，最后终端设备向网络上报测量结果，使得网络设备根据测量结果给终端设备进行定位。
需要说明的是，终端设备从网络设备接收配置信息可以携带多组频率信息与波束信息的关联信息，也可以携带修正信息，终端设备可以根据配置信息携带的不同信息进行测量结果的获取，下面分别对两种情况进行说明。
一、配置信息携带多组频率信息与波束信息的关联信息：
本实施例中，终端设备从网络设备接收到的配置信息携带多组频率信息与波束信息的关联信息，终端设备在接收到参考信号之后，根据多组频率信息与波束信息的关联信息获取测量结果，然后将测量结果向网络设备上报。
具体请参阅图8，图8为本申请实施例中角度定位的方法一个实施例的示意图，本申请实施例中角度定位方法实施例包括：
101、终端设备从网络设备接收配置信息，其中，配置信息包括参考信号的配置信息，以及N组频率信息与M组波束信息的关联信息，N为大于1的整数，M为大于1的整数；
终端设备从网络设备接收配置信息，配置信息包括参考信号的配置信息以及N组频率信息与M组波束信息的关联信息，其中，参考信号的配置信息可以包括带宽、接收波束指示、序列、密度、符号位置或周期，可以理解的是，参考信号的配置信息已经在标准中定义，可以参考标准的定义，这不对本申请实施例造成限定。多组频率信息与波束信息的关联关系可以为波束辐射模式信息、参考信号、频率和辐射模式的关联关系。另外，终端设备还可以接收网络设备不同的参考信号的配置信息所对应的不同参考信号标识，终端设备可以根据标识准确且迅速的找寻到所需的参考信号的配置信息，提高本申请的可行性。
可选地，N组频率信息与M组波束信息的关联信息中的N可以等于M，即为频率信息与波束信息一一对应，而在本申请实施例的一种实现方式中，频率信息与波束信息的关联信息可以参考如下表1以及表2所示的示例进行配置。
请参阅表1以及表2，表1为频率信息与定位参考信号资源之间配置关系的一个示例，表2为频率信息与信道状态信息参考信号资源之间配置关系的一个示例，在实际应用中，对关联信息进行配置也可以是其他配置形式，比如，通过信令进行配置。

其中，波束信息可以为波束的主瓣旁瓣朝向，零陷角度，主瓣旁瓣增益，水平或垂直上某一或多个特定方向的波束增益幅度、波束增益的相位信息。在实际应用中，波束信息还可以包括其他信息，例如每个波束的中心指向，即最大增益方向，波束ID或波束的信息对应的载波频率或中心频率，一个或多个参考信号接收相对功率与基站离开角的对应关系。
可选地，频率信息可以通过绝对无线载频信道编号(absolute radio-frequency channel number，ARFCN)进行指示，可以理解的是，频率信息也可以包含在一个小区配置中，也就是说为每个小区配置不同的波束信息或不同的BWP。
可选地，频率信息可以对应一个频率范围。根据表1以及表2所示，例如频率信息1对应28GHz～30GHz，频率信息2对应30.5GHz～32GHz。或者，也可以指示一个频率范围的中心频点，例如对于某一频率f,终端设备应选择频率信息中离该频率最接近的频率信息对应的波束辐射模式进行估计。可选地，频率信息还可以是一个相对频率信息。例如，频率信息是一个参考频率点和测量频率点之间的频率差值，或，是一个参考频率点和测量频率点之间的频率比值。
可选地，不同频率信息对应的波束信息可以分别进行配置。部分频率信息可以进行分组，同一组的频率信息共用一个波束信息，例如网络设备指示一个小区分组或频率信息分组，同一个组中所存在的频率信息共用一个波束信息。当频率信息指示一个频率范围的时候，如表3以及表4所示，网络设备定义一个频率范围(frequency range，FR)，针对不同的频率范围配置不同的波束信息，请参阅表3以及表4，表3为频率范围名称与对应频率范围之间配置关系的一个示例，表4为频率范围名称与信道状态信息参考信号资源之间配置关系的一个示例，在实际应用中，对关联信息进行配置也可以是其他配置形式，具体此处不做限定：

FR2 24250MHz-52600MHz
表4

可选地，除了上述配置方式，网络设备还可以为终端设备配置一个参考频率点、测量频点与参考频率点之间的频域偏移量与波束的对应关系，例如，终端设备参考频率点可以为终端设备当前主小区的中心频点或载波频点。请参阅表5，表5为频域偏移量与信道状态信息参考信号资源之间配置关系的一个示例。
表5
频域偏移量 信道状态信息参考信号资源1 信道状态信息参考信号资源2
偏移量1 波束信息11 波束信息12
偏移量2 波束信息21 波束信息22

第一种形式为，信令可以包括信道状态信息参考信号资源集合，其中，信道状态信息参考信号资源集合包括有信道状态信息参考信号资源集合对应的资源集合标识，一个或多个信道状态信息参考信号资源，一个或多个频域偏移量以及信道状态信息参考信号资源集合的其他信息。示例性地，如表5所示，多个信道状态信息参考信号资源可以包括信道状态信息参考信号资源1和信道状态信息参考信号资源2，多个频域偏移量可以包括偏移量1，偏移量2和偏移量3，信道状态信息参考信号资源集合的其他信息可以包括站点位置，发送信道状态信息参考信号资源的站点标识，和信道状态信息参考信号资源集合的周期。
具体地，每个信道状态信息参考信号资源中可以包括一个或多个波束辐射模式信息、空域滤波信息、时域域频资源映射信息和周期信息。可选地，波束辐射模式可以与信道状态信息参考信号资源集合中配置的频率偏移量关联。可选地，波束辐射模式与信道状态信息参考信号资源集合中配置的频率偏移量关联的方式可以是一一对应的，或，波束辐射模式与信道状态信息参考信号资源集合中配置的频率偏移量可以按照顺序关联，即第一个频率偏移信息与第一个频率偏移量关联，第二个频率偏移信息与第二个频率偏移量关联，以此类推。如表5所示，以信道状态信息参考信号资源1为例，对信道状态信息参考信号资 源的配置进行详细说明。终端设备获取信道状态信息参考信号资源1对应的资源标识，例如，信道状态信息参考信号资源1的标识为1，并获取信道状态信息参考信号资源1所对应的波束信息，另外，还可以获取空域滤波信息，即获取信道状态信息参考信号资源1所对应的资源级波束指示或准同位关系(quasi-clocation，QCL)，进一步地，获取波束辐射模式信息以及信道状态信息参考信号资源1的其他信息，如表5所示，偏移量1对应波束信息11，偏移量2对应波束信息21，偏移量3对应波束信息31，信道状态信息参考信号资源1的其他信息包括信道状态信息参考信号资源1的发射功率，周期，时域频域资源映射信息，或序列信息。上述配置中，如表5所示的频域偏移量中的偏移量与信道状态信息参考信号资源中的波束信息是一一对应的。
第二种形式为，信令可以包括信道状态信息参考信号资源集合，其中，信道状态信息参考信号资源集合包括有信道状态信息参考信号资源集合对应的资源集合标识，多个信道状态信息参考信号资源以及信道状态信息参考信号资源集合的其他信息。示例性地，如表5所示，多个信道状态信息参考信号资源可以包括信道状态信息参考信号资源1和信道状态信息参考信号资源2，信道状态信息参考信号资源集合的其他信息可以包括站点位置，发送信道状态信息参考信号资源的站点标识和信道状态信息参考信号资源集合的周期。
具体地，每个信道状态信息参考信号资源中可以包括一个或多个波束辐射模式信息、空域滤波信息、时域域频资源映射信息和周期信息。可选地，波束辐射模式信息包括频域偏移量与波束信息的关联关系。如表5所示，以信道状态信息参考信号资源2为例对信道状态信息参考信号资源的配置进行详细说明。终端设备获取信道状态信息参考信号资源2对应的资源标识，例如，信道状态信息参考信号资源2的标识为2，并获取信道状态信息参考信号资源2所对应的资源波束信息，另外，还可以获取空域滤波信息，即获取信道状态信息参考信号资源2所对应的资源级波束指示或QCL，进一步地，获取波束辐射模式信息以及信道状态信息参考信号资源2的其他信息，如表5所示，偏移量1对应波束信息12，偏移量2对应波束信息22，偏移量3对应波束信息32，信道状态信息参考信号资源2的其他信息包括信道状态信息参考信号资源2的发射功率，周期，时域频域资源映射信息，或序列信息。
可选地，本实施例中的波束信息与频域偏移量的对应关系可以配置在传输配置指示(transmission configuration indicator，TCI)中，表示与TCI状态或QCL信息关联的参考信号可以使用该TCI状态或QCL信息中的波束信息。
应理解，对于一个参考信号来说，其发送波束信息可以通过QCL信息指示，例如，参考信号A和参考信号B是空域准同位，则表示参考信号A和参考信号B可以使用相同的接收波束接收，或，可以使用相同发送波束发送。因此，网络设备可以将一个或多个QCL信息配置到TCI状态里，然后将TCI状态与不同的参考信号关联，即可以表示被关联的参考信号与TCI状态中的参考信号满足配置的QCL信息。
示例性地，为了便于理解，波束信息配置在TCL或QCL信息中的一种配置方式可以采用如下形式：
信令可以包括TCI状态，其中，TCI状态可以包括TCI状态对应的TCI状态标识和多 个QCL关系，每个QCL关系中包括一个QCL信息，每个QCL信息可以包括包括QCL信息参考信息资源的发送小区标识，QCL信息参考信息资源的BWP，QCL指示的参考信号类型以及参考信号信号标识，QCL类型和波束信息，其中，QCL类型包括QCL类型A,QCL类型B,QCL类型C,QCL类型D,其中，QCL类型D可以用于指示空间信息。另外，波束信息可以与频率范围，或，偏移量具有对应关系，具体关系的配置如表4以及表5所示的内容，具体此处不再赘述。
具体地，终端设备可以获取TCI状态，TCI状态中包括TCI状态标识和多个QCL关系，例如，TCI状态标识为1，TCI状态包括QCL关系1和QCL关系2，而QCL关系1包括QCL信息1，QCL关系2包括QCL信息2。
根据上述配置方式，当参考信号为CSI-RS时，且CSI-RS与TCI状态关联，终端设备可以确定CSI-RS的波束信息与TCI状态中的波束信息相同，即CSI-RS的发送的波束信息与TCI的配置的波束信息相同，或，CSI-RS的发送的波束信息与QCL信息中的配置的波束信息相同。另外，QCL信息可以不配置在TCI指示中,而是直接配置在参考信号的相关配置中。
102、终端设备接收参考信号的配置信息所对应的参考信号；

本实施例中，终端设备在通过步骤102接收到网络设备发送的参考信号的配置信息所对应的参考信号之后，可以基于频率信息与波束信息的关联关系测量参考信号得到测量结果。
可选地，当波束信息为多个参考信号接收相对功率与基站离开角的对应关系时，请参阅表6，表6为多个参考信号接收相对功率与基站离开角之间配置关系的一个示例：

波束信息21 基站离开角2 参考信号1接收相对功率21 参考信号2接收相对功率22
波束信息31 基站离开角3 参考信号1接收相对功率31 参考信号2接收相对功率32
具体地，多个不同的参考信号接收相对功率可以对应一个基站离开角，而波束信息则为多个不同的参考信号接收相对功率与基站离开角的对应关系，其中，接收相对功率可以是将某一指定参考信号的接收功率进行归一化的相对功率，而某一指定参考信号的接收功率可以为，参考信号的最大接收功率，幅度最大的参考信号所对应的接收功率，或，标识最小的参考信号所对应的接收功率。可选地，接收相对功率可以为离开角对应的集合内所有参考信号的接收功率相加的和，对该相加所得的和归一化到常数C后的功率值，C可以通过网络设备进行配置，或，通过协议确定C，例如，C可以等于1。
因此，终端设备可以在获取到参考信号之后，还可以通过测量得到不同的参考信号在不同频率范围内的接收功率，然后不同频率范围内的接收功率以及N组频率信息与M组波束信息的关联信息确定多组离开角，在所有频率范围内，选择多组离开角中接近程度最高的那一个作为角度信息，该角度信息属于测量结果。
示例性地，不同频率范围可以分别为28GHz～30GHz以及30GHz～32GHz。首先，终端设备测量不同的参考信号在28GHz～30GHz以及30GHz～32GHz分别的实际接收功率，然后，在28GHz～30GHz的频率范围内，终端设备选择一个可能的离开角A，根据网络设备配置的在28GHz～30GHz的频率范围内的M组波束信息，获取离开角A对应的M组波束的波束增益相对大小，并且与28GHz～30GHz范围内的实际接收功率的相对大小进行比较，确定两者接近程度，进一步地，终端设备再次选择一个可能的离开角B，根据网络设备配置的在28GHz～30GHz的频率范围内的M组波束信息，获取离开角B对应的M组波束的波束增益相对大小，并且与28GHz～30GHz范围内的实际接收功率的相对大小进行比较，确定两者接近程度，当终端设备获取到在28GHz～30GHz范围内所有可能的离开角度对应的波束增益相对大小与实际接收功率的相对大小的接近程度时，进一步地，对于30GHz～32GHz的频率范围，重复类似步骤，当终端设备获取到在30GHz～32GHz范围内所有可能的离开角度对应的波束增益相对大小与实际接收功率的相对大小的接近程度时，对比获取到的两个频率范围内所有的接近程度，将接近程度最高对应的离开角作为角度信息，该角度信息属于测量结果。
104、终端设备向网络设备上报测量结果。
本实施例中，终端设备在通过步骤103获取到测量结果后，终端设备会向网络设备上报测量结果，使得网络设备根据该测量结果确定终端设备的位置，从而完成终端设备所需的定位其中，网络设备可以是定位设备，也可以是基站。

应理解，对于一个参考信号来说，其发送波束信息可以通过QCL信息指示，例如，参考信号A和参考信号B是空域准同位，则表示参考信号A和参考信号B可以使用相同的接收波束接收，或，可以使用相同发送波束发送。因此，网络设备可以将一个或多个QCL信息配置到TCI状态里，然后将TCI状态与不同的参考信号关联，即可以表示被关联的参考信号与TCI状态中的参考信号满足配置的QCL信息。
示例性地，为了便于理解，波束修正信息配置在TCL或QCL信息中的一种配置方式可 以采用如下形式：
信令可以包括TCI状态，其中，TCI状态可以包括TCI状态对应的TCI状态标识和多个QCL关系，每个QCL关系中包括一个QCL信息，每个QCL信息可以包括包括QCL信息参考信息资源的发送小区标识，QCL信息参考信息资源的BWP，QCL指示的参考信号类型以及参考信号信号标识，QCL类型，和波束修正信息与频域偏移量的关联关系，其中，QCL类型包括QCL类型A,QCL类型B,QCL类型C,QCL类型D,其中，QCL类型D可以用于指示空间信息。

应理解，在实际应用中，频率修正信息的配置与波束修正信息的配置类似，此处不再赘述。

可以理解的是，对不同频点下的参考信号接收功率配置波束修正信息，可以通过下式进行计算确定不同频点下的波束修正信息，在实际应用中，对不同频点下的参考信号接收功率的波束修正信息进行配置也可以是其他计算方式，具体此处不做限定：
