Description

用于测量信号的方法和通信装置
本申请要求于2019年02月15日提交中国专利局、申请号为201910118107.9、申请名称为“用于测量信号的方法和通信装置”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
本申请涉及通信领域,并且更具体地,涉及一种用于测量信号的方法和通信装置。
背景技术
下行离开角(downlink angle of departure,DAOD)定义为接入网设备和终端设备之间下行电磁波传输时从接入网设备处观测的电磁波离开方向。接入网设备通过向终端设备发送多个不同波束方向的信号,终端设备接收并测量这多个不同波束方向的信号的接收功率,利用不同波束方向的信号的接收功率之间的比例关系,以及每个信号对应的波束方向,可以确定接入网设备和终端设备之间信道的DAOD。
然而,上述方法中由于测量的接收功率包括多个径的接收功率,因此测量的DAOD可能不准确。如何更准确的测量DAOD,是一个需要解决的问题。
发明内容
本申请提供一种用于测量信号的方法和通信装置,能够实现更准确的DAOD测量。
第一方面,提供了一种用于测量信号的方法,该方法可以由终端设备实现,可以由配置于终端设备中的芯片实现,本申请对此不作限定。以下主要以该方法由终端设备实现为例对该方法进行说明。
该方法包括:接收资源配置信息,资源配置信息包括第一参考信号集合配置信息,第一参考信号集合包括M个参考信号,所述M个参考信号中的N个参考信号为基准参考信号,M为大于1的整数,N为大于或者等于1的整数;接收所述M个参考信号;确定所述N个基准参考信号对应的N个第一径,以及,确定所述M个参考信号在所述N个第一径上的M*N个接收功率;上报测量结果,测量结果包括所述M*N个接收功率中的K*N个接收功率,其中K≤M。
可选地,测量结果中包括的接收功率可以是绝对接收功率,也可以是相对接收功率。绝对接收功率就是测量到的实际的接收功率,相对接收功率是指以某一参考信号的接收功率作为基准时,其他参考信号相对于该基准参考信号的接收功率。比如,将第一参考信号集合中参考信号#i的绝对接收功率和相对接收功率分别记作:P 1,i和P′ 1,i,i=1,2,……,M,那么,可以认为P′ 1,1=1,
Figure PCTCN2020074889-appb-000001
或者
Figure PCTCN2020074889-appb-000002
k=2,3,……,M。P′ 1,1可以不上报,但本申请对此不作限定。
本申请提供的用于测量信号的方法,终端设备通过上报同一径上的接收功率,使得定 位设备可以基于同一径上的接收功率,获得更准确的DAOD。比如,定位设备可以将终端设备上报的同一径的接收功率与接入网设备预先在较理想条件下测得的多个波束在不同出射角度上对应的接收功率进行匹配,由于较理想条件下一般不存在多径,因此匹配结果更准确,从而定位设备能够获得更准确的DAOD。
结合第一方面,在第一方面的某些实现方式中,所述N个基准参考信号为定位设备配置的,或者终端设备从M个参考信号中选择的。
在从第一参考信号集中选择基准参考信号时,终端设备可以根据第一参考信号集合中各参考信号对应的参考信号接收功率(reference signal received power,RSRP),选择RSRP最大的一个或多个参考信号作为基准参考信号。或者,终端设备可以选择时延最短的一个或多个参考信号作为基准参考信号。或者,终端设备也可以基于其他的准则选择基准参考信号,本申请对此不作限定。另外,一个参考信号集合中基准参考信号的数量或者最大数量可以由定位设备配置,比如通过资源配置信息配置,也可以由协议规定或者预先配置。
基于上述技术方案,定位设备可以灵活配置基准参信号,或者,终端设备可以灵活选择基准参考信号。
结合第一方面,在第一方面的某些实现方式中,所述N个基准参考信号对应N个空间接收滤波器;
以及,所述M个参考信号在所述N个第一径中任一第一径j上的M个接收功率为:通过所述第一径j对应的基准参考信号所对应的空间接收滤波器接收的所述M个参考信号在所述第一径j上的M个接收功率。
通过上报基于同一空间接收滤波器接收的参考信号在第一径上的接收功率,可以使得定位设备能够更准确的估计DAOD。
进一步地,每个空间接收滤波器为多个空间接收滤波器中使所述空间接收滤波器对应的基准参考信号的接收功率最大的空间接收滤波器。
也就是说,一个基准参考信号对应的空间接收滤波器为多个空间接收滤波器中最大化该基准参考信号对应的接收功率的空间接收滤波器。
通过使用最大化该基准参考信号对应的接收功率的空间接收滤波器接收基准参考信号,使得基于基准参考信号确定的径更准确,相应的径的接收功率也更准确。
另外,该测量结果还可以包括N个基准参考信号对应的N个空间接收滤波器的标识信息。
结合第一方面,在第一方面的某些实现方式中,所述K*N个接收功率包括所述N个第一径中每个第一径的M个接收功率中最大的K个接收功率,其中K<M。
进一步地,所述测量结果还包括所述K*N个接收功率对应的K*N个参考信号的标识信息。
通过上报所述N个第一径中每个第一径的M个接收功率中最大的K个接收功率,可以在不损失DAOD估计精度的前提下,节省信令开销。
结合第一方面,在第一方面的某些实现方式中,所述资源配置信息还包括第二参考信号集合配置信息,所述第二参考信号集合包括P个参考信号,所述P个参考信号中的Q个参考信号为基准参考信号,P为大于1的整数,Q为大于或者等于1的整数;
所述测量结果还包括P*Q个接收功率中的部分或全部;
以及,所述方法还包括:
接收所述P个参考信号;
确定所述Q个基准参考信号对应的Q个第一径,以及,确定所述P个参考信号在所述Q个第一径上的所述P*Q个接收功率。
可选地,第一参考信号集合和第二参考信号集合可以对应不同的小区,但本申请实施例对此不作限定。
基于上述技术方案,终端设备不仅上报第一参考信号集合中的参考信号在同一径上的接收功率,还上报第二参考信号集合中的参考信号在同一径上的接收功率,在第一参考信号集合和第二参考信号集合对应的小区对应不同接入网设备时,定位设备可以获得更多接入网设备的DAOD。进而基于多个接入网设备的DAOD,可以确定终端设备的位置。
结合第一方面,在第一方面的某些实现方式中,每个第一径为所述第一径对应的基准参考信号的多个径中接收功率最大的径。
根据上述准则选择第一径,有助于实现对反射径的DAOD估计。因为如果不选接收功率最大的径,而选首径,那么反射径的DAOD永远无法选择上,所以选择最大径。
结合第一方面,在第一方面的某些实现方式中,所述测量结果还包括所述N个第一径中除基准第一径之外的N-1个第一径分别相对于所述基准第一径的时延,N大于1。
终端设备通过上报多个径之间的时延差,从而使得定位设备可以根据该多个径对应的接收功率以及时延差,基于DAOD定位终端设备。
第二方面,提供了一种用于测量信号的方法,该方法可以由定位设备实现,可以由配置于定位设备中的芯片实现,本申请对此不作限定。以下主要以该方法由定位设备实现为例对该方法进行说明。
该方法包括:发送资源配置信息,所述资源配置信息包括第一参考信号集合配置信息,所述第一参考信号集合包括M个参考信号,所述M个参考信号中的N个参考信号为基准参考信号,M为大于1的整数,N为大于或者等于1的整数;

可选地,测量结果中包括的接收功率可以是绝对接收功率,也可以是相对接收功率。绝对接收功率就是测量到的实际的接收功率,相对接收功率是指以某一参考信号的接收功率作为基准时,其他参考信号相对于该基准参考信号的接收功率。比如,将第一参考信号集合中参考信号#i的绝对接收功率和相对接收功率分别记作:P 1,i和P′ 1,i,i=1,2,……,M,那么,可以认为P′ 1,1=1,

也就是说,一个基准参考信号对应的空间接收滤波器为多个空间接收滤波器中最大化该基准参考信号对应的接收功率的空间接收滤波器。
通过使用最大化该基准参考信号对应的接收功率的空间接收滤波器接收基准参考信号,使得基于基准参考信号确定的径更准确,相应的径的接收功率也更准确。
另外,该测量结果还可以包括N个基准参考信号对应的N个空间接收滤波器的标识信息。

基于上述技术方案,终端设备不仅上报第一参考信号集合中的参考信号在同一径上的 接收功率,还上报第二参考信号集合中的参考信号在同一径上的接收功率,在第一参考信号集合和第二参考信号集合对应的小区对应不同接入网设备时,定位设备可以获得更多接入网设备的DAOD。进而基于多个接入网设备的DAOD,可以确定终端设备的位置。
结合第二方面,在第二方面的某些实现方式中,每个第一径为所述第一径对应的基准参考信号的多个径中接收功率最大的径。
根据上述准则选择第一径,有助于实现对反射径的DAOD估计。因为如果不选接收功率最大的径,而选首径,那么反射径的DAOD永远无法选择上,所以选择最大径。
结合第二方面,在第二方面的某些实现方式中,所述测量结果还包括所述N个第一径中除基准第一径之外的N-1个第一径分别相对于所述基准第一径的时延,N大于1。
定位设备可以根据该多个径对应的接收功率以及时延差,基于DAOD定位终端设备。
第三方面,提供了一种用于测量信号的方法,该方法可以由定位接入网设备实现,可以由配置于接入网设备中的芯片实现,本申请对此不作限定。以下主要以该方法由接入网设备实现为例对该方法进行说明。

本申请提供的用于测量信号的方法,接入网设备通过配置第一参考信号集合,使得终端设备可以通过对该第一参考信号集合中的参考信号的测量,上报同一径上的接收功率,从而定位设备可以基于同一径上的接收功率,获得更准确的DAOD。
结合第三方面,在第三方面的某些实现方式中,所述方法还包括:接收请求消息;

本申请提供的用于测量信号的方法,接入网设备可以根据定位设备或者终端设备发送的同一径上的接收功率,获得更准确的DAOD。比如,接入网设备可以将定位设备或者终端设备发送的同一径的接收功率与其预先在较理想条件下测得的多个波束在不同出射角度上对应的接收功率进行匹配,由于较理想条件下一般不存在多径,因此匹配结果更准确,从而能够获得更准确的DAOD。
结合第三方面,在第三方面的某些实现方式中,所述方法还包括:发送用于指示所述DAOD的信息。
接入网设备通过向定位设备发送指示DAOD的信息,使得定位设备可以确定终端设备和接入网设备之间的DAOD。

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。
本申请实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System for Mobile communications,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统、未来的第五代(5th Generation,5G)通信系统或新无线接入技术(new radio Access Technology,NR)等。
本申请中的定位设备可以是为终端设备提供定位功能的装置或组件。比如,定位设备可以是定位管理功能(location management function,LMF)或者定位管理组件(location management component,LMC)。LMC可以集成在下一代无线接入网(next-generation radio access network,NG-RAN)侧的接入网设备上,因此定位设备可以是集成LMC的接入网设备。本申请中的接入网设备是一种部署在无线接入网中为终端设备提供无线通信功能的装置。接入网设备包括但不限于: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(BaseBand Unit,BBU),无线保真(Wireless Fidelity,WIFI)系统中的接入点(Access Point,AP)、无线中继节点、无线回传节点、传输点(transmission point,TP)或者发送接收点(transmission and reception point,TRP)等,还可以为5G,如,NR,系统中的gNB,或,传输点(TRP或TP),5G系统中的基站的一个或一组(包括多个天线面板)天线面板,或者,还可以为构成gNB或传输点的网络节点,如基带单元(BBU),或,分布式单元(distributed unit,DU)等。接入网设备还可以是云无线接入网络(cloud radio access network,CRAN)场景下的无线控制器。接入网设备还可以是可穿戴设备或车载设备等。
在一些部署中,gNB可以包括集中式单元(centralized unit,CU)和DU。gNB还可以包括射频单元(radio unit,RU)。CU实现gNB的部分功能,DU实现gNB的部分功能,比如,CU实现无线资源控制(radio resource control,RRC),分组数据汇聚层协议(packet data convergence protocol,PDCP)层的功能,DU实现无线链路控制(radio link control,RLC)层、媒体接入控制(media access control,MAC)层和物理(physical,PHY)层的功能。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+CU发送的。可以理解的是,接入网设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。
本申请中的终端设备也可以称为用户设备(user equipment,UE)、接入终端、用户单元、用户站、移动站、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。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、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(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)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)中的无线终端等等。本申请的实施例对应用场景不做限定。
图1是应用本申请实施例的一个通信系统的架构示意图。如图1所示,该系统中,终端设备(以UE为例)通过LTE-Uu和/或NR-Uu接口分别经由下一代基站(next-generation eNodeB,ng-eNB)和gNB连接到无线接入网;无线接入网通过NG-C接口经由接入和移动性管理功能(access and mobility management function,AMF)连接到核心网。其中,下一代无线接入网(next-generation radio access network,NG-RAN)包括一个或多个ng-eNB;NG-RAN也可以包括一个或多个gNB;NG-RAN还可以包括一个或多个ng-eNB以及gNB。ng-eNB为接入5G核心网的LTE基站,gNB为接入5G核心网的5G基站。核心网包括AMF与定位管理功能(location management function,LMF)等功能。其中,AMF用于实现接入管理等功能,LMF用于实现定位等功能。AMF与LMF之间通过NLs接口连接。LMF是一种部署在核心网中为UE提供定位功能的装置或组件。
图2是应用本申请实施例的传输信号的另一个通信系统的架构示意图。图1与图2的系统架构的区别在于,图1的定位管理功能的装置或组件(比如LMF)部署在核心网中, 图2的定位管理功能的装置或组件(比如定位管理组件(location management component,LMC))可以部署在基站中。如图2所示,gNB中包含LMC。LMC是LMF的部分功能组件,可以集成在NG-RAN侧的gNB中。
应理解,上述图1或图2的系统中,可以包括一个或多个gNB,单个或多个终端设备。单个gNB可以向单个终端设备或多个终端设备传输数据或控制信令。多个gNB也可以同时为单个终端设备传输数据或控制信令。
还应理解,上述图1或图2的系统中包括的设备或功能节点只是示例性地描述,并不对本申请实施例构成限定,事实上,图1或图2的系统中还可以包含其他与图中示意的设备或功能节点具有交互关系的网元或设备或功能节点,这里不作具体限定。
如图3所示,接入网设备和终端设备之间下行电磁波传输时从接入网设备处观测的电磁波离开方向定义为下行离开角(downlink angle of departure,DAOD)。已知一种通过测量多个不同波束方向的信号的参考信号接收功率(reference signal received power,RSRP)确定DAOD的技术。具体地,接入网设备向终端设备发送多个参考信号,每个参考信号对应一个发送波束,终端设备测量并上报这多个参考信号对应的RSRP。根据这多个参考信号对应的多个RSRP之间的比例关系以及每个参考信号对应的发送波束的方向,可以确定DAOD。应理解,参考信号对应的RSRP也可以称为该参考信号对应的波束的RSRP。
下面以接入网设备发送三个参考信号为例,对上述测量DAOD的方法进行说明。参见图4,接入网设备发送的三个参考信号对应的发送波束分别为波束#1、波束#2和波束#3,终端设备对这三个波束的RSRP进行测量,并将测量结果反馈给接入网设备或者定位设备。其中,波束#1因为没有对准终端设备,所以测得的RSRP最低。波束#2稍微对准了终端设备,所以测得的RSRP较高。波束#3相对对准了终端设备,所以测得的RSRP最高。接入网设备或者定位设备在获得测量结果后,将测量结果与预先在较理想条件下测得的多个波束在不同出射角度上对应的RSRP进行匹配,发现波束#1、波束#2和波束#3对应的RSRP之间的比例关系与预先测得的30度方向上三个波束之间的比例关系更匹配,从而确定终端设备在30度方向上。
根据RSRP的定义可知,RSRP包括了整个信道的功率,也就是说RSRP为信道上多个径的接收功率之和。然而,在理想条件下测得的多个波束在不同出射角度上对应的RSRP是基于单一径获得的,因此在进行RSRP匹配时,结果可能不准确,即获得DAOD可能不准确。
有鉴于此,本申请提供了一种用于测量信号的方法,终端设备通过上报同一径上的接收功率,使得定位设备可以基于同一径上的接收功率,获得更准确的DAOD。
在介绍本申请实施例之前,首先对本申请中涉及的几个名词作简单说明。
1、波束
波束可以是空域滤波器(spatial domain filter),或者称空间滤波器(spatial filter)或空间参数(spatial parameter)。用于发送信号的波束可以称为发送波束(transmission beam,Tx beam),或者可以称为空域发送滤波器(spatial domain transmission filter)或空间发射参数(spatial transmission parameter);用于接收信号的波束可以称为接收波束(reception beam,Rx beam),或者可以称为空域接收滤波器(spatial domain receive filter)或空间接收参数(spatial RX parameter)。
发送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。
此外,波束可以是宽波束,或者窄波束,或者其他类型波束。形成波束的技术可以是波束赋形技术或者其他技术。波束赋形技术具体可以为数字波束赋形技术、模拟波束赋形技术或者混合数字/模拟波束赋形技术等。
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。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。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。
2、参考信号与参考信号资源
参考信号可以用于波束测量,即通过测量参考信号获得波束质量信息。用于衡量波束质量的参数包括RSRP,但不限于此。例如,波束质量也可以通过参考信号接收质量(reference signal receiving quality,RSRQ),信噪比(signal-noise ratio,SNR),信号与干扰噪声比(signal to interference plus noise ratio,SINR,简称信干噪比)等参数衡量。
参考信号资源可用于配置参考信号的传输属性,例如,时频资源位置、端口映射关系、功率因子以及扰码等,具体可参考现有技术。接入网设备可基于参考信号资源发送参考信号,终端设备可基于参考信号资源接收参考信号。
本申请实施例中涉及的参考信号例如可以包括信道状态信息参考信号(channel state information reference signal,CSI-RS)、同步信号块(synchronization signal block,SSB)以及探测参考信号(sounding reference signal,SRS)。与此对应地,参考信号资源可以包括CSI-RS资源(CSI-RS resource)、SSB资源、SRS资源(SRS resource)。
需要说明的是,上述SSB也可以称为同步信号/物理广播信道块(synchronization signal/physical broadcast channel block,SS/PBCH block),所对应的SSB资源也可以称为同步信号/物理广播信道块资源(SS/PBCH block resource),可简称为SSB resource。在某些情况下,SSB也可以是指SSB资源。在本申请实施例中,SSB可以视为SS/PBCH block,SSB资源可以视为SS/PBCH block resource。
为了区分不同的参考信号资源,每个参考信号资源可对应于一个参考信号资源的标识,例如,CSI-RS资源标识(CSI-RS resource indicator,CRI)、SSB资源标识(SSB resource indicator,SSBRI)、SRS资源索引(SRS resource index,SRI)。其中,SSB资源标识也可以称为SSB标识(SSB index)。
应理解,上文中列举的参考信号以及相应的参考信号资源仅为示例性说明,不应对本申请构成任何限定,本申请并不排除在未来的协议中定义其他参考信号来实现相同或相似功能的可能。
应理解,本申请定位设备配置参考信号可以理解为定位设备配置参考信号资源。
下面将结合附图详细说明本申请提供的用于测量信号的方法和装置。
应理解,在下文示出的实施例中,第一、第二仅为便于区分不同的对象,而不应对本申请构成任何限定。例如,区分不同的参考信号集合、不同的径等。
还应理解,本申请实施例中的“协议”可以是指通信领域的标准协议,例如可以包括LTE协议、NR协议以及应用于未来的通信系统中的相关协议,本申请对此不做限定。
还应理解,“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和 /或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。“至少一个”是指一个或一个以上;“A和B中的至少一个”,类似于“A和/或B”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和B中的至少一个,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。
本申请的技术方案可以应用于无线通信系统中,例如,图1中所示的通信系统或图2所示的通信系统。在应用于图1所示的系统中时,本申请中的定位设备可以是图1所示的系统中的LMF,接入网设备可以是ng-eNB或gNB,终端设备可以是UE。在应用于图2所示的系统中时,本申请中的定位设备可以是图2所示的系统中的LMC或集成该LMC的gNB,接入网设备可以是ng-eNB或gNB,终端设备可以是UE。
图5是从设备交互的角度示出的用于测量信号的方法500的示意性流程图。如图所示,图5中示出的方法500可以包括S510至S570。下面结合图5对方法500进行详细说明。应理解,图5中仅以执行主体为定位设备、接入网设备和终端设备为例进行说明,在具体实施时,定位设备也可以替换为配置于定位设备中的芯片,相应地,接入网设备也可以替换为配置于接入网设备中的芯片,终端设备也可以替换为配置于终端设备中的芯片。
S510,接入网设备向定位设备发送请求消息。相应地,定位设备接收接入网设备发送的请求消息。其中,该请求消息用于请求参考信号集合配置信息。
S520,接入网设备向定位设备发送参考信号集合配置信息。相应地,定位设备接收参考信号集合配置信息
比如,第一接入网设备可以向定位设备发送第一参考信号集合配置信息。第一参考信号集合配置信息用于配置第一参考信号集合。第一参考信号集合包括M个参考信号,该M个参考信号中的N个参考信号为基准参考信号,M>1,N≥1,且M和N均为整数。
再如,第二接入网设备可以向定位设备发送第二参考信号集合配置信息。第二参考信号集合配置信息用于配置第二参考信号集合。第二参考信号集合包括P个参考信号,该P个参考信号中的Q个参考信号为基准参考信号,P>1,Q≥1,且P和Q均为整数。
应理解,接入网设备可以自行向定位设备发送参考信号集合配置信息,也可以根据定位设备的请求发送参考信号集合配置信息,也就是说,S510为可选步骤。
S530,定位设备向终端设备发送资源配置信息。相应地,终端设备接收定位设备发送的资源配置信息。
其中,资源配置信息可以包括一个或多个参考信号集合配置信息,每个参考信号集合配置信息用于配置对应的参考信号集合。也就是说,该资源配置信息用于配置一个或多个参考信号集合,每个参考信号集合可以包括多个参考信号。
比如,该资源配置信息可以包括第一参考信号集合配置信息。再如,该资源配置信息除包括第一参考信号集合配置信息以外,还可以包括第二参考信号集合配置信息。本申请中,基准参考信号可以由接入网设备确定,也可以由定位设备确定的,或者由由终端设备自己确定或者选择。比如,该N个基准参考信号可以是第一接入设备确定的,也可以是定位设备确定的,或者是由终端设备自己确定或者选择的。再如,该Q个基准参考信号可以是第二接入设备确定的,也可以是定位设备确定的,或者是由终端设备自己确定或者选择的。
在从一个参考信号集中选择基准参考信号时,终端设备可以根据该参考信号集合中各参考信号对应的RSRP,选择RSRP最大的一个或多个参考信号作为基准参考信号。或者,终端设备可以选择时延最短的一个或多个参考信号作为基准参考信号。或者,终端设备也可以基于其他的准则选择基准参考信号,本申请对此不作限定。另外,一个参考信号集合中基准参考信号的数量或者最大数量可以由定位设备配置,比如通过资源配置信息配置,也可以由协议规定或者预先配置。
应理解,该资源配置信息除包括第一参考信号集合配置信息和第二参考信号集合配置信息以外,还可以包括其他参考信号集合配置信息,本申请对该资源配置信息所配置的参考信号集合的数量不作限定。还应理解,每个参考信号集合中所包括的参考信号的数量可以相等,也可以不等,以及,每个参考信号集合中的基准参考信号的数量可以相等,也可以不等,本申请对此不作限定。比如,上述中,P和M可以相等,也可以不等,N和Q可以相等,也可以不等。
另外,若该资源配置信息包括多个参考信号集合配置信息,该多个参考信号集合配置信息可以对应不同的小区。比如,一个小区可以对应一个参考信号集合配置信息,也可以对应多个参考信号集合配置信息。所述小区可以是服务小区也可以是邻小区,本申请对此不作限定。
S540,接入网设备向终端设备发送参考信号。相应地,终端设备接收参考信号。
具体地,该资源配置信息所包括的一个或多个参考信号集合配置信息所对应的小区分别所对应的接入网设备,向终端设备发送相应地参考信号,终端设备根据对应的参考信号集合配置信息,接收参考信号。比如,第一参考信号集合配置信息对应第一小区,则第一小区对应的第一接入网设备向终端设备发送该M个参考信号,相应地终端设备接收该M个参考信号。第二参考信号集合配置信息对应第二小区,则第二小区对应的第二接入网设备向终端设备发送该P个参考信号,相应地终端设备接收该P个参考信号。
S550,终端设备确定每个基准参考信号对应的第一径,以及确定每个基准参考信号所属的参考信号集合中的每个参考信号在对应的第一径上的接收功率。
比如,终端设备确定第一参考信号集合中的N个基准参考信号对应的N个第一径,以及,确定第一参考信号集合中的M个参考信号在N个第一径上的M*N个接收功率。终端设备还可以确定第二参考信号集合中的Q个基准参考信号对应的Q个第一径,以及,确定第二参考信号集合中的P个参考信号在Q个第一径上的P*Q个接收功率。
应理解,同一参考信号集合中的多个基准参考信号对应的多个第一径可以不同,但本申请对此不作限定。比如,第一参考信号集合中的N个基准参考信号对应的N个第一径可以不同。属于不同参考信号集合中的两个或更多个基准参考信号对应的第一径可以相同,也可以不同,本申请对此不作限定。
在一种实现方式中,每个基准参考信号可以对应一个空间接收滤波器。终端设备所确定的任一基准参考信号j所属的参考信号集合中的每个参考信号在基准参考信号j对应的第一径j上的接收功率为:通过基准参考信号j对应的空间接收滤波器接收的基准参考信号j所属的参考信号集合中的每个参考信号在第一径j上的接收功率。
以第一参考信号集合为例来讲,终端设备所确定的第一参考信号集合中的M个参考信号在该N个第一径上的M*N个接收功率包括:终端设备通过该N个基准参考信号中的 每个基准参考信号对应的空间接收滤波器接收的该M个参考信号在每个基准参考信号对应的第一径上的M个接收功率。其中,该M个参考信号在N个第一径中任一第一径j上的M个接收功率为:通过第一径j对应的基准参考信号所对应的空间接收滤波器接收的该M个参考信号在第一径j上的M个接收功率。比如,该N个基准参考信号包括基准参考信号#1和基准参考信号#2,基准参考信号#1对应空间接收滤波器#1和第一径#1,基准参考信号#2对应空间接收滤波器#2和第一径#2,第一参考信号集合中的M个参考信号在该N个第一径上的M*N个接收功率包括:终端设备通过空间接收滤波器#1接收的该M个参考信号在第一径#1上的M个接收功率,以及,终端设备通过空间接收滤波器#2接收的该M个参考信号在第一径#2上的M个接收功率。
进一步地,每个空间接收滤波器为多个空间接收滤波器中使该空间接收滤波器对应的基准参考信号的接收功率最大的空间接收滤波器。也就是说,一个基准参考信号对应的空间接收滤波器为最大化该基准参考信号对应的RSRP的空间接收滤波器。
举例来说,终端设备有多个空间接收滤波器,各空间接收滤波器接收基准参考信号#1时对应的接收功率不同,并且空间接收滤波器#1接收基准参考信号#1时对应的接收功率最大,则可以将空间接收滤波器#1作为基准参考信号#1对应的空间接收滤波器。即,空间接收滤波器#1为最大化基准参考信号#1对应的RSRP的空间接收滤波器。再如,上述各空间接收滤波器接收基准参考信号#2时对应的接收功率不同,并且空间接收滤波器#2接收基准参考信号#2时对应的接收功率最大,则可以将空间接收滤波器#2作为基准参考信号#2对应的空间接收滤波器。即,空间接收滤波器#2为最大化基准参考信号#2对应的RSRP的空间接收滤波器。
在一种实现方式中,每个第一径为该第一径对应的基准参考信号的多个径中接收功率最大的径。也就是说,一个基准参考信号对应的第一径为该基准参考信号对应的RSRP下接收功率最大的径。
具体来讲,终端设备通过一个基准参考信号对应的空间接收滤波器接收该基准参考信号,若该基准参考信号包含多个径,则终端设备通过确定各个径对应的接收功率,可以将对应的接收功率最大的径确定为该基准参考信号对应的第一径。
比如,基准参考信号#1包括直射径和反射径,终端设备通过基准参考信号#1对应的空间接收滤波器#1接收基准参考信号#1,若直射径对应的接收功率大于反射径对应的接收功率,则该直射径可以认为是基准参考信号#1对应的第一径#1。
应理解,本申请中涉及的接收功率可以是RSRP,但本申请对此不作限定。
S560,终端设备上报测量结果。相应地,定位设备接收该测量结果。
其中,测量结果包括在S550中确定的部分或全部接收功率。即,测量结果包括部分或全部基准参考信号所属的参考信号集合中的部分或全部参考信号在对应的第一径上的接收功率。
举例来说,若资源配置信息配置了三个参考信号集合,测量结果可以仅包括该三个参考信号集合中的部分参考信号集合中的部分或全部参考信号对应的接收功率,或者测量结果可以包括这三个参考信号集合中的部分或全部参考信号对应的接收功率。比如,测量结果可以包括该M个参考信号在该N个第一径上的M*N个接收功率中的K*N个接收功率,其中K≤M。进一步地,测量结果还可以包括该P个参考信号在该Q个第一径上的P*Q 个接收功率中的部分或全部。
在一种实现方式中,针对任意参考信号集合,终端设备可以上报该参考信号集合中在对应的第一径上的多个接收功率中接收功率较大的接收功率进行上报。比如,在K<M的情况下,所述K*N个接收功率包括该N个第一径中每个第一径的M个接收功率中最大的K个接收功率。举例来说,第一参考信号集合中包括8个参考信号,分别为参考信号#1至参考信号#8,8个参考信号中参考信号#1为基准参考信号,并且参考信号#1对应第一径#1,那么若参考信号#1至参考信号#4中任一参考信号在第一径#1上的接收功率大于参考信号#5至参考信号#8中任一参考信号在第一径#1上的接收功率,则终端设备可以仅上报参考信号#1至参考信号#4在第一径#1上的接收功率。
在上报接收功率时,终端设备可以上报绝对接收功率,也可以上报相对接收功率。绝对接收功率就是测量到的实际的接收功率,相对接收功率是指以某一参考信号的接收功率作为基准时,其他参考信号相对于该基准参考信号的接收功率。比如,以第一参考信号集合为例,将第一参考信号集合中参考信号#i的绝对接收功率和相对接收功率分别记作:P 1,i和P′ 1,i,i=1,2,……,M,那么,可以认为P′ 1,1=1,

或者
Figure PCTCN2020074889-appb-000006
k=2,3,……,M。P′ 1,1可以不上报,但本申请对此不作限定。
应理解,在未作特殊说明的情况下,本申请中的接收功率可以是绝对接收功率。还应理解,本申请中的参考信号的接收功率可以是参考信号的RSRP。
在一种实现方式中,若终端设备上报的是一个参考信号集合中的部分参考信号在对应的第一径上的接收功率,终端设备还可以上报该部分参考信号的标识。
在一种实现方式中,若一个参考信号集合中包括对应多个不同第一径的多个基准参考信号,终端设备还可以上报这多个第一径之间的时延差。比如,终端设备可以选择这多个第一径中对应的时延中的最小值作为参考值,上报其他时延相对于该值的大小。又如,终端设备也可以选择某个特定的基准参考信号对应的第一径的时延作为基准,上报其他时延相对于该值的大小。
在一种实现方式中,该测量结果还可以包括各基准参考信号所对应的空间接收滤波器的标识信息。
S570,定位设备根据测量结果,确定DAOD。
在一种实现方式中,定位设备预先获取各接入网设备预先在较理想条件下测得的多个波束在不同出射角度上对应的RSRP,根据终端设备上报的测量结果与在较理想条件下测得的多个波束在不同出射角度上对应的RSRP进行匹配,可以确定DAOD。
在另一种实现方式中,定位设备可以将对应的测量结果发送给各接入网设备。比如,定位设备可以将所述K*N个接收功率发送给第一接入网设备,第一接入网设备可以根据该K*N个接收功率,确定DAOD。比如,第一接入网设备可以根据预先在较理想条件下测得的多个波束在不同出射角度上对应的RSRP与该K*N个接收功率,确定DAOD。
进一步地,接入网设备在确定DAOD后,还可以向定位设备发送指示DAOD的信息。比如,第一接入网设备可以向定位设备发送指示其所确定的DAOD的信息,从而定位设备可以确定DAOD。本申请提供的用于测量信号的方法,终端设备通过上报同一径上的接收功率,使得定位设备可以基于同一径上的接收功率,获得更准确的DAOD。比如,定位设备可以将终端设备上报的同一径的接收功率与接入网设备预先在较理想条件下测得的多个波束在不同出射角度上对应的RSRP进行匹配,由于较理想条件下一般不存在多径, 因此匹配结果更准确,从而定位设备能够获得更准确的DAOD。
另外,终端设备还可以上报多个径之间的时延差,从而定位设备可以根据该多个径对应的接收功率以及时延差,基于DAOD定位终端设备。
下面分别结合图6和图7,详细说明根据本申请提供的用于测量信号的方法的两个具体示例。
图6示出了不同参考信号对应的不同径上的接收功率的一个示意图。参见图6,接入网设备发送了3个参考信号,分别为参考信号#1、参考信号#2和参考信号#3,其中,参考信号#2为基准参考信号。应理解,参考信号#1、参考信号#2和参考信号#3可以是同一参考信号集合中的多个参考信号,比如可以是第一参考信号集合中的3个参考信号,即第一参考信号集合对应该接入网设备。参考信号的多个径中包括图中所示的直射径#1和反射径#2。应理解,参考信号还可以包括更多个径,这里仅以两个径为例进行说明,并不对本申请构成任何限定。在终端设备侧,终端设备通过接收波束#1接收参考信号#1、参考信号#2和参考信号#3。接收波束#1可以是终端设备的多个接收波束中使参考信号#2的接收功率最大的接收波束。可以看出,在直射径#1和反射径#2所对应的接收功率中,参考信号#2在直射径#1上的接收功率大于在反射径#2上的接收功率,因此终端设备可以上报参考信号#1、参考信号#2和参考信号#3在直射径#1上的接收功率。参考信号#1、参考信号#2和参考信号#3在直射径#1上的接收功率用于确定接入网设备和终端设备之间的DAOD,具体地确定方法参见上文描述,这里不再赘述。
图7示出了不同参考信号对应的不同径上的接收功率的一个示意图。图7中分别以参考信号#1和参考信号#2作为基准参考信号。图7中的上图与图6相同,具体可以参见对图6所作的说明,这里不再赘述。图7中的下图是以参考信号#1作为基准参考信号终端设备接收参考信号的示意图。参见图7中的下图,终端设备通过接收波束#2接收参考信号#1、参考信号#2和参考信号#3。接收波束#2可以是终端设备的多个接收波束中使参考信号#1的接收功率最大的接收波束。可以看出,在直射径#1和反射径#2所对应的接收功率中,参考信号#1在反射径#2上的接收功率大于在直射径#1上的接收功率,因此终端设备除上报参考信号#1、参考信号#2和参考信号#3在直射径#1上的接收功率外,还可以上报参考信号#1、参考信号#2和参考信号#3在反射径#2上的接收功率。此外,终端设备还可以上报直射径#1和反射径#2之间的时延差。参考信号#1、参考信号#2和参考信号#3在直射径#1上的接收功率和参考信号#1、参考信号#2和参考信号#3在反射径#2上的接收功率可以用于确定接入网设备和终端设备之间的DAOD,具体地确定方法参见上文描述,这里不再赘述。另外,结合直射径#1和反射径#2之间的时延差,还可以进行基于DAOD的终端设备的定位。
需要注意的是,图7中参考信号#1、参考信号#2和参考信号#3在直射径#1上的接收功率是通过接收波束#1接收参考信号测量得到的,参考信号#1、参考信号#2和参考信号#3在反射径#2上的接收功率是通过接收波束#2接收参考信号测量得到的。
