Description

一种上行参考信号的关联方法及通信装置
本申请要求于2020年09月28日提交中国专利局、申请号为202011045811.5、申请名称为“一种上行参考信号的关联方法及通信装置”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
本申请涉及定位技术领域，尤其涉及一种上行参考信号的关联方法及通信装置。
背景技术
在移动通信系统中，对终端设备进行定位是重要的功能之一。当前的定位技术包括下行定位技术和上行定位技术。所谓的上行定位技术是指：由终端设备向网络设备发送上行参考信号。例如，该上行参考信号可以是探测参考信号(sounding reference signal，SRS)。网络设备对上行参考信号进行测量，并将测量结果发送至定位管理设备。由定位管理设备根据测量结果确定终端设备的位置信息。
然而在实践中发现，目前在低频的通信系统中，定位技术的定位精度不高，其主要原因是低频的NR通信系统单个上行参考信号最大带宽为100MHz，而基于定时测距的定位方法精度直接与带宽相关联。一般而言，带宽越大，测距精度越高。因此，如何对现有的上行参考信号配置结构进行增强以实现大带宽上行参考信号的配置，从而提升定位精度是目前亟待解决的问题。
发明内容
本申请实施例提供了一种上行参考信号的关联方法及通信装置，能够实现大带宽上行参考信号的配置。
第一方面，本申请提供一种上行参考信号的关联方法，该方法包括：第一网络设备生成第一配置信息，该第一配置信息指示不同载波上同时发送的上行参考信号之间的关联关系；具有关联关系的上行参考信号共天线端口或具有关联关系的上行参考信号具有相位差；第一网络设备向终端设备发送第一配置信息。
在第一方面所描述的方法中，网络侧能够向终端设备配置哪些上行参考信号之间共天线端口或配置哪些上行参考信号之间具有相位差。多个上行参考信号之间共天线端口，表示多个上行参考信号经历完全相同的信道，可以等效地看成终端设备发送了一个新上行参考信号，该新上行参考信号的带宽相当于多个上行参考信号的带宽之和。因此，使多个上行参考信号之间共天线端口可以扩大信号带宽。因此，通过向终端设备配置哪些上行参考信号之间共天线端口，能够实现大带宽上行参考信号的配置。通过向终端设备配置哪些上行参考信号之间具有相位差，网络设备可以估计出这些上行参考信号之间的该相位差，然后通过该相位差对上行参考信号的信道相位进行补偿，从而使多个上行参考信号之间共天线端口，以扩大信号带宽。因此，通过向终端设备配置哪些上行参考信号之间具有相位差，也能够实现大带宽上行参考信号的配置。
在一种可能的实现中，第一网络设备生成第二配置信息，该第二配置信息指示不同载波 上同时发送的上行参考信号之间的关联关系；第一网络设备向定位管理设备发送第二配置信息。基于该可能的实现方式，可以通过第二配置信息向定位管理设备指示不同载波上同时发送的上行参考信号之间的关联关系，从而定位管理设备可以向第二网络设备指示不同载波上同时发送的上行参考信号之间的关联关系。从而第二网络设备可以对具有关联关系的上行参考信号进行联合测量，得到测量结果。
在一种可能的实现中，第一配置信息和/或第二配置信息还指示具有关联关系的上行参考信号共天线端口或具有关联关系的上行参考信号具有固定相位差。基于该可能的实现方式，能够灵活地向终端设备和/或定位管理设备配置关联关系的类型。
在一种可能的实现中，在终端设备发送具有关联关系的上行参考信号的过程中，具有关联关系的上行参考信号之间的相位差为固定值。可选的，在终端设备发送具有关联关系的上行参考信号的过程中，具有关联关系的上行参考信号之间的相位差变化很小也可以理解为在终端设备发送具有关联关系的上行参考信号的过程中，具有关联关系的上行参考信号之间的相位差为固定值。通过使具有关联关系的上行参考信号之间的相位差在终端设备发送具有关联关系的上行参考信号的过程中为固定值，有利于终端设备准确地估计出具有关联关系的上行参考信号之间的相位差。
在一种可能的实现中，当上行参考信号具有多天线端口时，具有关联关系的上行参考信号的相同天线端口号对应同一个天线端口。即当上行参考信号具有多天线端口时，具有关联关系的上行参考信号的相同天线端口号对应天线端口共端口。
在一种可能的实现中，第一配置信息指示不同载波上同时发送的上行参考信号之间的关联关系的方式具体为：第一配置信息指示不同载波上同时发送的上行参考信号资源之间的关联关系。也就是说，第一配置信息可以通过指示不同载波上同时发送的上行参考信号资源之间的关联关系来指示不同载波上同时发送的上行参考信号之间的关联关系，这样能够准确地指示不同载波上同时发送的上行参考信号之间的关联关系。例如，如果第一配置信息指示不同载波上同时发送的上行参考信号资源1和上行参考信号资源2具有关联关系，那么第一配置信息相当于指示了上行参考信号资源1对应的上行参考信号和上行参考信号资源2对应的上行参考信号具有关联关系。

请参见图1，图1是本申请实施例提供的一种系统架构的示意图。如图1所示，该系统架构包括终端设备、第一网络设备、第二网络设备和定位管理设备。
本申请实施例中涉及的终端设备，是用户侧的一种用于接收或发射信号的实体。终端设备可以是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。终端设备也可以是连接到无线调制解调器的其他处理设备。终端设备可以与无线接入网(radio access network，RAN)进行通信。终端设备也可以称为无线终端、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(access point)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment，UE)等等。终端设备可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，终端设备还可以是个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、等设备。常见的终端设备例如包括：汽车、无人机、机械臂、手机、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，例如智能手表、智能手环、计步器等，但本申请实施例不限于此。

本申请实施例中，上行参考信号为终端设备向网络侧的接入网设备(如基站)发送的参考信号。上行参考信号可以为探测参考信号(sounding reference signal，SRS)或者为其他上行参考信号。下面以SRS为例，对上行参考信号支持的定位技术进行介绍：
1、上行到达时间差(UL-TDOA)定位技术。该定位技术中，各小区对终端设备发送的SRS测量上行链路相对到达时间(uplink relativeTime of arrival，UL-RTOA)，并将测量结果上报给LMF。LMF基于测量结果对终端设备进行定位。
2、上行链路到达角(uplink angle of arrival，UL-AOA)定位技术。该定位技术中，各小区对终端设备发送的SRS测量UL-AoA，并将测量结果上报给LMF。LMF基于测量结果对终端设备进行定位。
3、多小区往返时间(multi-round trip time，Multi-RTT)定位技术。该定位技术中，终端设备对各小区发送的PRS测量用户设备接收-发送时间差(UE-RxTxTimeDiff，UE Rx meDiffime。received)，并将测量结果上报给LMF；各小区对终端设备发送的SRS测量gNB接收-发送时间差(gNB-RxTxTimeDiff，gNB Rx–Tx time difference)，并将测量结果上报给LMF。LMF基于测量结果对终端设备进行定位。
在以上定位技术中，具体可由各小区中的TRP或RP来测量SRS，后文以TRP测量SRS为例进行说明。下面对与SRS配置相关的以下几个概念进行介绍，如图3所示：
1、服务小区/载波。每个服务小区可以包括一个载波或者两个载波，服务小区包括两个 载波时其中一个载波为普通上行载波，另一个载波为辅助上行载波SUL。每个载波包括一个或多个BWP。
2、BWP。BWP为一个载波上的一个部分带宽，对应了一套资源块(resource block，RB)集合、子载波间隔、循环前缀(CP)类型。Rel-15和Rel-16中，一个载波上可以配置多个BWP，但是在一个载波上同一个时刻最多只有一个激活BWP。终端在激活的BWP上进行数据、上行控制、SRS的发送。一个BWP上可以配置一个或多个SRS资源集。
3、SRS资源集。一个SRS资源集包含一个或多个SRS资源，一个SRS资源集内的SRS资源具有相同的周期性、SRS功控参数。
4、SRS资源。SRS资源为SRS配置的最小粒度，一个SRS资源对应一个SRS的发送波束。
目前在低频的通信系统中，定位技术的定位精度不高，其主要原因是低频的NR通信系统单个上行参考信号最大带宽为100MHz，而基于定时测距的定位方法精度直接与带宽相关联。一般而言，带宽越大，测距精度越高。因此，如何对现有的上行参考信号配置结构进行增强以实现大带宽上行参考信号的配置，从而提升定位精度是目前亟待解决的问题。
为了实现大带宽上行参考信号的配置，本申请实施例提供了一种上行参考信号的关联方法及通信装置，下面对本申请实施例提供的上行参考信号的关联方法及通信装置进一步进行详细描述：
请参见图4，图4是本申请实施例提供的一种上行参考信号的关联方法的流程示意图。如图4所示，该上行参考信号的关联方法包括如下步骤401～步骤403。图4所示的方法执行主语可以为终端设备、第一网络设备，或主语可以为终端设备中的芯片、第一网络设备中的芯片。图4以终端设备、第一网络设备为方法的执行主体为例进行说明。其中：
401、第一网络设备生成第一配置信息，该第一配置信息指示不同载波上同时发送的上行参考信号之间的关联关系。
其中，第一网络设备可以是终端设备的服务网络设备，例如，第一网络设备是终端设备的服务基站。
例如，第一配置信息可以指示终端设备的载波1和载波2上同时发送的上行参考信号具有关联关系，以及指示终端设备的载波3和载波4上同时发送的上行参考信号具有关联关系。
再如，第一配置信息可以指示终端设备的载波1的BWP1和载波2的BWP3上同时发送的上行参考信号具有关联关系，以及指示终端设备的载波1的BWP2和载波2的BWP4上同时发送的上行参考信号具有关联关系。
再如，第一配置信息可以指示终端设备的SRS资源集11和SRS资源集31上同时发送的上行参考信号具有关联关系。SRS资源集11为载波1的BWP1中的SRS资源集。SRS资源集31为载波2的BWP3中的SRS资源集。
其中，同时发送的上行参考信号可以理解为符号相同的上行参考信号。或者，同时发送的上行参考信号可以理解为符号不同，但因定时不同，导致同时发送的上行参考信号。
在一种可能的实现中，第一配置信息指示不同载波上同时发送的上行参考信号之间的关联关系的方式具体为：第一配置信息指示不同载波上同时发送的上行参考信号资源之间的关联关系。也就是说，第一配置信息可以通过指示不同载波上同时发送的上行参考信号资源之间的关联关系来指示不同载波上同时发送的上行参考信号之间的关联关系，这样能够准确地指示不同载波上同时发送的上行参考信号之间的关联关系。例如，如果第一配置信息指示不同载波上同时发送的上行参考信号资源1和上行参考信号资源2具有关联关系，那么第一配 置信息相当于指示了上行参考信号资源1对应的上行参考信号和上行参考信号资源2对应的上行参考信号具有关联关系。
可选的，第一配置信息包括多个载波的配置信息，该载波的配置信息包括该载波的索引以及该载波中的带宽部分BWP的配置信息，该BWP的配置信息包括该BWP的索引以及该BWP中的上行参考信号资源集的配置信息，该上行参考信号资源集的配置信息包括该上行参考信号资源集的索引以及该上行参考信号资源集中的上行参考信号资源的配置信息。也就是说，该第一配置信息还可指示终端设备在哪些载波上具有哪些BWP，以及在这些BWP下具有哪些上行参考信号资源集，以及在这些上行参考信号资源集上具有哪些上行参考信号资源。
例如，如图5所示，终端设备具有3个载波，分别为载波1～载波3。第一配置信息包括载波1的配置信息～载波3的配置信息。以载波1的配置信息为例。载波1的配置信息包括载波1的索引。由于载波1中包括BWP1和BWP2，载波1的配置信息还包括BWP1的配置信息和BWP2的配置信息。可选的，载波1的配置信息中还可包括载波1的其他属性信息。
以BWP1的配置信息为例进行说明。如图5所示，BWP1的配置信息中包括BWP1的索引。由于BWP1中包括SRS资源集11和SRS资源集12，BWP1的配置信息中还包括SRS资源集11的配置信息和SRS资源集12的配置信息。
SRS资源集11的配置信息中包括SRS资源集11的索引。由于SRS资源集11中包括SRS资源111和SRS资源112，SRS资源集11的配置信息中还包括SRS资源111的配置信息和SRS资源112的配置信息。其中，SRS资源111的配置信息包括SRS资源111的索引。SRS资源112的配置信息包括SRS资源112的索引。
同理，SRS资源集12的配置信息中包括SRS资源集12的索引、SRS资源121的配置信息和SRS资源122的配置信息。其中，SRS资源121的配置信息包括SRS资源121的索引。SRS资源122的配置信息包括SRS资源122的索引。
也就是说，第一配置信息指示了终端设备在载波1下包括BWP1和BWP2。其中，BWP1包括SRS资源集11和SRS资源集12。SRS资源集11包括SRS资源111和SRS资源112。SRS资源集12包括SRS资源121和SRS资源122。BWP2包括SRS资源集21和SRS资源集22。SRS资源集21包括SRS资源211和SRS资源212。SRS资源集22包括SRS资源221和SRS资源222。其他载波同理，在此不赘述。
第一配置信息指示不同载波上同时发送的上行参考信号资源之间的关联关系可以有以下3种具体实现方式：
①第一上行参考信号资源集的配置信息中还包括至少一个第一索引信息，该第一索引信息包括第二载波的索引、第二载波中第二BWP的索引和第二BWP中第二上行参考信号资源集的索引，以指示第一上行参考信号资源集和至少一个第二上行参考信号资源集中同时发送的上行参考信号资源具有关联关系，第一上行参考信号资源集和该至少一个第二上行参考信号资源集为第一配置信息配置的不同载波上的资源集。方式①相当于通过指示不同载波上的上行参考信号资源集之间的关联关系来指示不同载波上同时发送的上行参考信号资源之间的关联关系，这样有利于节省信令开销。
可选的，如果上行参考信号资源为SRS资源。第一上行参考信号资源集的配置信息可以是SRS-ResourceSet或SRS-PosResourceSet。
例如，第一上行参考信号资源集的配置信息的信元结构可以如下：
Figure PCTCN2021120609-appb-000001
Figure PCTCN2021120609-appb-000002
Figure PCTCN2021120609-appb-000003
其中，上述信元结构中，划线部分的SRS-ResourceSetID-Info-r17表示第一索引信息。划线部分的servingCellId-r17表示第二载波的索引。划线部分的uplinkBWP-r17表示第二BWP的索引。划线部分的srs-ResourceSetId-r17表示第二上行参考信号资源集的索引。从上述信元结构中可以看出，第一上行参考信号资源集的配置信息可以包括一个或多个第一索引信息。
再如，如图6所示，假设载波1下的SRS资源集11的配置信息中包括{载波2的索引、载波2下的BWP3的索引以及BWP3下的SRS资源集31的索引}和{载波3的索引、载波3下的BWP5的索引以及BWP5下的SRS资源集51的索引}。那么第一配置信息指示SRS资源集11、SRS资源集31和SRS资源集51中同时发送的SRS资源具有关联关系。
可选的，如果每个载波中的上行参考信号资源集的索引不相同，第一上行参考信号资源集的配置信息中也可以只包括至少一个第二上行参考信号资源集的索引，不需要包括第二载波的索引和第二BWP的索引。
可选的，也可以不通过上述方式①来指示第一上行参考信号资源集与至少一个第二上行参考信号资源集中同时发送的上行参考信号资源具有关联关系。例如，可以配置第一上行参考信号资源集与至少一个第二上行参考信号资源集的索引相同，以指示第一上行参考信号资源集与至少一个第二上行参考信号资源集中同时发送的上行参考信号资源具有关联关系。
②第一BWP的配置信息中还包括至少一个第二索引信息，该第二索引信息包括第二载波的索引以及第二载波中第二BWP的索引，以指示第一BWP和至少一个第二BWP中同时发送的上行参考信号资源具有关联关系，第一BWP和第二BWP为第一配置信息配置的不同载波上的BWP。方式②相当于通过指示不同载波上的BWP之间的关联关系来指示不同载波上同时发送的上行参考信号资源之间的关联关系，这样有利于节省信令开销。
可选的，如果上行参考信号资源为SRS资源。第一BWP的配置信息中包括SRS配置(SRS-Config)。具体可以是第一BWP的配置信息中的SRS配置中包括至少一个第二索引信息。或者可以是第一BWP的配置信息中除SRS配置之外的位置包括至少一个第二索引信息。 SRS-ResourceSet或SRS-PosResourceSet是在SRS配置中。
例如，SRS配置的信元结构可以如下：
Figure PCTCN2021120609-appb-000004
Figure PCTCN2021120609-appb-000005
其中，上述信元结构中，划线部分的AssociatedSRS-Info-r17表示第二索引信息。划线部分的servingCellId-r17表示第二载波的索引。划线部分的uplinkBWP-r17表示第二BWP的索引。从上述信元结构中可以看出，第一BWP的配置信息可以包括一个或多个第二索引信息。
再如，如图7所示，假设载波1下的BWP1的配置信息中包括{载波2的索引、载波2下的BWP3的索引}和{载波3的索引、载波3下的BWP5的索引}。那么第一配置信息指示BWP1、BWP3和BWP5中同时发送的SRS资源具有关联关系。
可选的，如果每个载波中的BWP的索引不相同，第一BWP的配置信息中也可以只包括至少一个第二BWP的索引，不需要包括第二载波的索引。
可选的，也可以不通过上述方式②来指示第一BWP的索引与至少一个第二BWP中同时发送的上行参考信号资源具有关联关系。例如，可以配置第一BWP的索引与至少一个BWP的索引相同，以指示第一BWP与该至少一个第二BWP中同时发送的上行参考信号资源具有关联关系。
③第一载波的配置信息中还包括至少一个第二载波的索引，以指示第一载波和至少一个第二载波中同时发送的上行参考信号资源具有关联关系，第一载波和第二载波为第一配置信息配置的不同载波。方式③相当于通过指示不同载波之间的关联关系来指示不同载波上同时发送的上行参考信号资源之间的关联关系，这样有利于节省信令开销。
可选的，第一载波的配置信息可以为ServingCellConfig。
例如，第一载波的配置信息的信元结构可以如下：
Figure PCTCN2021120609-appb-000006
Figure PCTCN2021120609-appb-000007
Figure PCTCN2021120609-appb-000008
其中，上述划线部分的SRS-AssociatedCell-Info-r17中的servingCellId-r17表示第二BWP的索引。
再如，如图8所示，假设载波1的配置信息中包括载波2的索引和载波3的索引。那么第一配置信息指示载波1、载波2和载波3中同时发送的上行参考信号资源具有关联关系。
可选的，在上述方式①～方式③中，第二载波的索引包括以下一项或多项：第二载波所在服务小区的索引、用于指示第二载波为所在服务小区的常规上行载波或辅助上行载波的指示信息。例如，如果第二载波所在服务小区中只包括一个上行载波，则第二载波的索引可以通过第二载波所在服务小区的索引来表示。如果第二载波所在服务小区中包括两个上行载波，则第二载波的索引可以通过第二载波所在服务小区的索引+用于指示第二载波为所在服务小区的常规上行载波还是辅助上行载波的指示信息来表示。基于该可选的方式，有利于准确地指示第二载波。
在另一种可能的实现中，第一配置信息指示不同载波上同时发送的上行参考信号之间的关联关系的方式具体为：第一配置信息指示不同载波上的上行参考信号资源集之间的关联关系。第一配置信息指示不同载波上的上行参考信号资源集之间的关联关系的具体实现方式可以参见上述方式①中的描述，在此不赘述。例如，如果第一配置信息指示第一上行参考信号资源集与至少一个第二上行参考信号资源集具有关联关系，则第一上行参考信号资源集与至 少一个第二上行参考信号资源集中同时发送的上行参考信号之间具有关联关系。
在又一种可能的实现中，第一配置信息指示不同载波上同时发送的上行参考信号之间的关联关系的方式具体为：第一配置信息指示不同载波上的BWP之间的关联关系。第一配置信息指示不同载波上的BWP之间的关联关系的具体实现方式可以参见上述方式②中的描述，在此不赘述。例如，如果第一配置信息指示第一BWP与至少一个第二BWP具有关联关系，则第一BWP与至少一个第二BWP中同时发送的上行参考信号之间具有关联关系。
在又一种可能的实现中，第一配置信息指示不同载波上同时发送的上行参考信号之间的关联关系的方式具体为：第一配置信息指示不同载波之间的关联关系。第一配置信息指示不同载波之间的关联关系的具体实现方式可以参见上述方式③中的描述，在此不赘述。例如，如果第一配置信息指示第一载波与至少一个第二载波具有关联关系，则第一载波与至少一个第二载波中同时发送的上行参考信号之间具有关联关系。
402、第一网络设备向终端设备发送第一配置信息。
本申请实施例中，第一网络设备生成第一配置信息之后，向终端设备发送该第一配置信息。
403、终端设备发送具有关联关系的上行参考信号；具有关联关系的上行参考信号共天线端口或具有关联关系的上行参考信号具有相位差。
本申请实施例中，终端设备接收该第一配置信息之后，发送具有关联关系的上行参考信号。
其中，天线端口定义为某天线端口在一个符号上承载的信道可以被该天线端口在另一个符号上承载的信号推测出来；换句话说，如果某天线端口在一个符号上承载的信道可以由另一个天线端口在另一个符号上承载的信道推测出来，那么这两个天线端口为同一天线端口。本申请实施例中具有关联关系的上行参考信号共天线端口是指具有关联关系的上行参考信号的天线端口为同一天线端口。具有关联关系的上行参考信号共天线端口也可以理解为：具有关联关系的上行参考信号信道相同，或具有关联关系的上行参考信号相位连续，或具有关联关系的上行参考信号相位相同。
终端设备发送具有关联关系的上行参考信号时，终端设备使具有关联关系的上行参考信号是共天线端口的，或者使具有关联关系的上行参考信号具有相位差。例如，假设不同载波上同时发送的SRS 111、SRS 311和SRS 511具有关联关系。如果具有关联关系的SRS共天线端口，SRS 111、SRS 311和SRS 511会经历完全一样的信道，第二网络设备会同时测量SRS 111、SRS 311和SRS 511经历的信道。可以等效地看成终端设备发送了一个带宽相当于SRS 111、SRS 311和SRS 511之和的新SRS，第二网络设备也接收了这一个新SRS，相当于扩大了信号带宽。由于定位精度很大程度上取决于信号带宽，因此可以提高定位精度。
再如，假设不同载波上同时发送的SRS 111、SRS 311和SRS 511具有关联关系。如果具有关联关系的SRS具有相位差，即SRS 111、SRS 311和SRS 511经历的信道除了存在一个相位差，其余都一样。这样一方面第二网络设备可以估计出该相位差，然后通过该相位差对SRS 111、SRS 311和SRS 511中的某些SRS的信道相位进行补偿，就可使SRS 111、SRS 311和SRS 511的信道具有相同的相位，从而使SRS 111、SRS 311和SRS 511共天线端口。根据之前的分析，使SRS 111、SRS 311和SRS 511共天线端口相当于扩大了信号带宽。由于定位精度很大程度上取决于信号带宽，因此可以提高定位精度。另一方面，即使第二网络设备没有办法估计出该相位差，也不对相位差进行补偿，第二网络设备依然可以对SRS 111、SRS 311、SRS 511各自信道上的测量结果进行合并，以获取频率分集增益，提升定位精度，但是无法 获得等效大带宽增益。
可见，基于图4所描述的方法，网络侧能够向终端设备配置哪些上行参考信号之间共天线端口或配置哪些上行参考信号之间具有相位差。多个上行参考信号之间共天线端口，表示多个上行参考信号经历完全相同的信道，可以等效地看成终端设备发送了一个新上行参考信号，该新上行参考信号的带宽相当于多个上行参考信号的带宽之和。因此，使多个上行参考信号之间共天线端口可以扩大信号带宽。因此，通过向终端设备配置哪些上行参考信号之间共天线端口，能够实现大带宽上行参考信号的配置。通过向终端设备配置哪些上行参考信号之间具有相位差，网络设备可以估计出这些上行参考信号之间的该相位差，然后通过该相位差对上行参考信号的信道相位进行补偿，从而使多个上行参考信号之间共天线端口，以扩大信号带宽。因此，通过向终端设备配置哪些上行参考信号之间具有相位差，也能够实现大带宽上行参考信号的配置。
在一种可能的实现中，在终端设备发送具有关联关系的上行参考信号的过程中，具有关联关系的上行参考信号之间的相位差为固定值。可选的，在终端设备发送具有关联关系的上行参考信号的过程中，具有关联关系的上行参考信号之间的相位差变化很小也可以理解为在终端设备发送具有关联关系的上行参考信号的过程中，具有关联关系的上行参考信号之间的相位差为固定值。通过使具有关联关系的上行参考信号之间的相位差在终端设备发送具有关联关系的上行参考信号的过程中为固定值，有利于终端设备准确地估计出具有关联关系的上行参考信号之间的相位差。例如，假设不同载波上同时发送的SRS 111、SRS 311和SRS 511具有关联关系。在终端设备发送具有关联关系的SRS的过程中，SRS 111和SRS 311之间的相位差为固定值1，SRS 111和SRS 511之间的相位差为固定值2，SRS 311和SRS511之间的相位差为固定值3。固定值1、固定值2和固定值3可以相同或不同。
在一种可能的实现中，当上行参考信号具有多天线端口时，具有关联关系的上行参考信号的相同天线端口号对应同一个天线端口。即当上行参考信号具有多天线端口时，具有关联关系的上行参考信号的相同天线端口号对应天线端口共端口。例如，假设不同载波上同时发送的SRS 111、SRS 311和SRS 511具有关联关系。SRS 111具有两个天线端口，天线端口号分别为天线端口#1和天线端口#2，SRS 311具有两个天线端口，天线端口号分别为天线端口#1和天线端口#2，SRS 511具有两个天线端口，天线端口号分别为天线端口#1和天线端口#2。SRS 111的天线端口#1、SRS 311的天线端口#1和SRS 511的天线端口#1对应同一个天线端口。SRS 111的天线端口#2、SRS 311的天线端口#2和SRS 511的天线端口#2对应同一个天线端口。
在一种可能的实现中，第一配置信息还指示具有关联关系的上行参考信号共天线端口或具有关联关系的上行参考信号具有相位差。例如，协议可以规定具有以下两种关联类型：具有关联关系的上行参考信号共天线端口和具有关联关系的上行参考信号具有相位差。第一网络设备可以根据需求从这两种关联类型中选择一种关联类型，并通过第一配置信息向终端设备指示选择的关联类型。终端设备接收第一配置信息之后，基于与第一配置信息指示的关联类型发送具有关联关系的上行参考信号。基于该可能的实现方式，网络侧能够灵活地向终端设备配置关联关系的类型。
可选的，也可不通过第一配置信息来指示关联关系的类型，协议可以直接规定某一种关联类型。例如，协议可以直接规定具有关联关系的上行参考信号共天线端口，或者，协议可以直接规定具有关联关系的上行参考信号具有相位差。
请参见图9，图9是本申请实施例提供的一种上行参考信号的关联方法的流程示意图。如图9所示，该上行参考信号的关联方法包括如下步骤901～步骤907。图9所示的方法执行主语可以为终端设备、第一网络设备、第二网络设备和定位管理设备，或主语可以为终端设备中的芯片、第一网络设备中的芯片、第二网络设备中的芯片和定位管理设备中的芯片。图9以终端设备、第一网络设备、第二网络设备和定位管理设备为方法的执行主体为例进行说明。其中：
901、第一网络设备生成第一配置信息，该第一配置信息指示不同载波上同时发送的上行参考信号之间的关联关系。
902、第一网络设备向终端设备发送第一配置信息。
其中，步骤901和步骤902的具体实现方式可参见上述步骤401和步骤402的具体实现方式，在此不赘述。
903、第一网络设备生成第二配置信息，该第二配置信息指示不同载波上同时发送的上行参考信号之间的关联关系。
其中，步骤903和步骤904可以在步骤901和步骤902之前执行，或者可以在步骤901和步骤902之后执行，或者步骤903和步骤904可以与步骤901和步骤902同时执行。
其中，第二配置信息指示的关联关系可以与第一配置信息指示的关联关系相同或不同。例如，第一配置信息指示SRS资源集11、SRS资源集31和SRS资源集51中同时发送的SRS具有关联关系。第二配置信息也指示SRS资源集11、SRS资源集31和SRS资源集51中同时发送的SRS具有关联关系。
再如，第一配置信息指示BWP1、BWP3和BWP5中同时发送的SRS具有关联关系。第二配置信息指示SRS资源集11、SRS资源集31和SRS资源集51中同时发送的SRS具有关联关系。或者，第二配置信息指示载波1、载波2和载波3中同时发送的SRS具有关联关系。载波1包括BWP1，BWP1包括SRS资源集11。载波2包括BWP3，BWP3包括SRS资源集31。载波3包括BWP5，BWP5包括SRS资源集51。
再如，第一配置信息指示载波1、载波2和载波3中同时发送的SRS具有关联关系。第二配置信息指示载波1、载波2和载波3中同时发送的SRS具有关联关系。
在一种可能的实现中，第二配置信息指示不同载波上同时发送的上行参考信号之间的关联关系的方式具体为：第二配置信息指示不同载波上同时发送的上行参考信号资源之间的关联关系。也就是说，第二配置信息可以通过指示不同载波上同时发送的上行参考信号资源之间的关联关系来指示不同载波上同时发送的上行参考信号之间的关联关系，这样能够准确地指示不同载波上同时发送的上行参考信号之间的关联关系。例如，如果第二配置信息指示不同载波上同时发送的上行参考信号资源1和上行参考信号资源2具有关联关系，那么第二配置信息相当于指示了上行参考信号资源1对应的上行参考信号和上行参考信号资源2对应的上行参考信号具有关联关系。
可选的，第二配置信息包括多个载波的配置信息，该载波的配置信息包括该载波的索引以及该载波中的上行参考信号资源集的配置信息，该上行参考信号资源集的配置信息包括该上行参考信号资源集的索引以及该上行参考信号资源集中的上行参考信号资源的配置信息。也就是说，该第二配置信息还可指示终端设备在哪些载波上具有哪些上行参考信号资源集，以及在这些上行参考信号资源集上具有哪些上行参考信号资源。第二配置信息中指示的上行参考信号资源集可以是载波中激活的BWP上的上行参考信号资源集。一个载波可以同时激活一个上行参考信号资源集。
例如，第一配置信息如图6所示。其中，载波1上BWP1是激活的，载波2上BWP3是激活的，载波3上BWP5是激活的。如图10所示，第二配置信息包括载波1的配置信息～载波3的配置信息。载波1的配置信息包括载波1的索引、SRS资源集11的配置信息和SRS资源集12的配置信息。载波2的配置信息包括载波2的索引、SRS资源集31的配置信息和SRS资源集32的配置信息。载波3的配置信息包括载波3的索引、SRS资源集51的配置信息和SRS资源集52的配置信息。
也就是说，第二配置信息指示了终端设备在载波1下包括SRS资源集11和SRS资源集12。SRS资源集11包括SRS资源111和SRS资源112。SRS资源集12包括SRS资源121和SRS资源122。并且指示了终端设备在载波2下包括SRS资源集31和SRS资源集32。SRS资源集31包括SRS资源311和SRS资源312。SRS资源集32包括SRS资源321和SRS资源322。并且指示了终端设备在载波3下包括SRS资源集51和SRS资源集52。SRS资源集51包括SRS资源511和SRS资源512。SRS资源集52包括SRS资源521和SRS资源522。
第二配置信息指示不同载波上同时发送的上行参考信号资源之间的关联关系可以有以下2种具体实现方式：
①第三上行参考信号资源集的配置信息中还包括至少一个第三索引信息，该第三索引信息包括第四载波的索引、第四载波中第四上行参考信号资源集的索引，以指示第三上行参考信号资源集和至少一个第四上行参考信号资源集中同时发送的上行参考信号资源具有关联关系，第三上行参考信号资源集和该至少一个第四上行参考信号资源集为第二配置信息配置的不同载波上的资源集。方式①相当于通过指示不同载波上的上行参考信号资源集之间的关联关系来指示不同载波上同时发送的上行参考信号资源之间的关联关系，这样有利于节省信令开销。
其中，第二配置信息指示关联关系的方式①与第一配置信息指示关联关系的方式①的原理相同，在此不赘述。
可选的，如果每个载波中的上行参考信号资源集的索引不相同，第三上行参考信号资源集的配置信息中也可以只包括至少一个第四上行参考信号资源集的索引，不需要包括第四载波的索引。
可选的，也可以不通过上述第二配置信息指示关联关系的方式①来指示第三上行参考信号资源集与至少一个第四上行参考信号资源集中同时发送的上行参考信号资源具有关联关系。例如，可以配置第三上行参考信号资源集与至少一个第四上行参考信号资源集的索引相同，以指示第三上行参考信号资源集与至少一个第四上行参考信号资源集中同时发送的上行参考信号资源具有关联关系。
②第三载波的配置信息中还包括至少一个第四载波的索引，以指示第三载波和该至少一个第四载波中同时发送的上行参考信号资源具有关联关系，第三载波和该至少一个第四载波为第二配置信息配置的不同载波。方式②相当于通过指示不同载波之间的关联关系来指示不同载波上同时发送的上行参考信号资源之间的关联关系，这样有利于节省信令开销。
其中，第二配置信息指示关联关系的方式②与第一配置信息指示关联关系的方式③的原理相同，在此不赘述。
可选的，在第二配置信息指示关联关系的方式①和方式②中，第四载波的索引包括以下一项或多项：第四载波所在服务小区的索引、用于指示第四载波为所在服务小区的常规上行载波或辅助上行载波的指示信息。例如，如果服务小区中只包括一个上行载波，则第二载波的索引可以通过第四载波所在服务小区的索引来表示。如果服务小区中包括两个上行载波， 则第二载波的索引可以通过第四载波所在服务小区的索引+用于指示第四载波为所在服务小区的常规上行载波还是辅助上行载波的指示信息来表示。
在另一种可能的实现中，第二配置信息指示不同载波上同时发送的上行参考信号之间的关联关系的方式具体为：第二配置信息指示不同载波上的上行参考信号资源集之间的关联关系。第二配置信息指示不同载波上的上行参考信号资源集之间的关联关系的具体实现方式可以参见第二配置信息指示关联关系的方式①中的描述，在此不赘述。例如，如果第二配置信息指示第三上行参考信号资源集与指示一个第四上行参考信号资源集具有关联关系，则第三上行参考信号资源集与指示一个第四上行参考信号资源集中同时发送的上行参考信号之间具有关联关系。
在又一种可能的实现中，第二配置信息指示不同载波上同时发送的上行参考信号之间的关联关系的方式具体为：第二配置信息指示不同载波之间的关联关系。第二配置信息指示不同载波之间的关联关系的具体实现方式可以参见上述第二配置信息指示关联关系的方式②中的描述，在此不赘述。例如，如果第二配置信息指示第三载波与指示一个第四载波具有关联关系，则第三载波与指示一个第四载波中同时发送的上行参考信号之间具有关联关系。
904、第一网络设备向定位管理设备发送第二配置信息。
本申请实施例中，第一网络设备生成第二配置信息之后，向定位管理设备发送第二配置信息。
905、定位管理设备向第二网络设备发送第三配置信息，该第三配置信息还指示不同载波上同时发送的上行参考信号之间的关联关系。
本申请实施例中，定位管理设备接收第一网络设备发送的第二配置信息之后，向第二网络设备发送第三配置信息。
其中，第三配置信息可以是基于第二配置信息生成的。第三配置信息可以包括第二配置信息的全部内容或部分内容。
例如，第一配置信息指示SRS资源集11、SRS资源集31和SRS资源集51中同时发送的SRS具有关联关系。第二配置信息也指示SRS资源集11、SRS资源集31和SRS资源集51中同时发送的SRS具有关联关系。第三配置信息也指示SRS资源集11、SRS资源集31和SRS资源集51中同时发送的SRS具有关联关系。或者，第三配置信息指示SRS资源集11和SRS资源集31中同时发送的SRS具有关联关系。
再如，第一配置信息指示载波1、载波2和载波3中同时发送的SRS具有关联关系。第二配置信息指示载波1、载波2和载波3中同时发送的SRS具有关联关系。第三配置信息也指示载波1、载波2和载波3中同时发送的SRS具有关联关系。或者，第三配置信息指示载波1和载波2中同时发送的SRS具有关联关系。
在一种可能的实现中，第三配置信息指示不同载波上同时发送的上行参考信号之间的关联关系的方式具体为：第三配置信息指示不同载波上同时发送的上行参考信号资源之间的关联关系。也就是说，第三配置信息可以通过指示不同载波上同时发送的上行参考信号资源之间的关联关系来指示不同载波上同时发送的上行参考信号之间的关联关系，这样能够准确地指示不同载波上同时发送的上行参考信号之间的关联关系。例如，如果第三配置信息指示不同载波上同时发送的上行参考信号资源1和上行参考信号资源2具有关联关系，那么第三配置信息相当于指示了上行参考信号资源1对应的上行参考信号和上行参考信号资源2对应的上行参考信号具有关联关系。
可选的，第三配置信息包括多个载波的配置信息，载波的配置信息包括该载波的索引以 及该载波中的上行参考信号资源集的配置信息，上行参考信号资源集的配置信息包括该上行参考信号资源集的索引以及该上行参考信号资源集中的上行参考信号资源的配置信息。也就是说，该第三配置信息还可指示终端设备在哪些载波上具有哪些上行参考信号资源集，以及在这些上行参考信号资源集上具有哪些上行参考信号资源。第三配置信息中指示的上行参考信号资源集可以是载波中激活的BWP上的上行参考信号资源集。
第三配置信息指示不同载波上同时发送的上行参考信号资源之间的关联关系可以有以下2种具体实现方式：
①第五上行参考信号资源集的配置信息中还包括至少一个第四索引信息，第四索引信息包括第六载波的索引、第六载波中第六上行参考信号资源集的索引，以指示第五上行参考信号资源集和至少一个第六上行参考信号资源集中同时发送的上行参考信号资源具有关联关系，第五上行参考信号资源集和至少一个第六上行参考信号资源集为第三配置信息配置的不同载波上的资源集。方式①相当于通过指示不同载波上的上行参考信号资源集之间的关联关系来指示不同载波上同时发送的上行参考信号资源之间的关联关系，这样有利于节省信令开销。
其中，第三配置信息指示关联关系的方式①与第一配置信息指示关联关系的方式①的原理相同，在此不赘述。
可选的，如果每个载波中的上行参考信号资源集的索引不相同，第五上行参考信号资源集的配置信息中也可以只包括至少一个第六上行参考信号资源集的索引，不需要包括第六载波的索引。
可选的，也可以不通过上述方式①来指示第五上行参考信号资源集与至少一个第六上行参考信号资源集中同时发送的上行参考信号资源具有关联关系。例如，可以配置第五上行参考信号资源集与至少一个第六上行参考信号资源集的索引相同，以指示第五上行参考信号资源集与至少一个第六上行参考信号资源集中同时发送的上行参考信号资源具有关联关系。
②第五载波的配置信息中还包括至少一个第六载波的索引，以指示第五载波和至少一个第六载波中同时发送的上行参考信号资源具有关联关系，第五载波和该至少一个第六载波为第三配置信息配置的不同载波。方式②相当于通过指示不同载波之间的关联关系来指示不同载波上同时发送的上行参考信号资源之间的关联关系，这样有利于节省信令开销。
其中，第三配置信息指示关联关系的方式②与第一配置信息指示关联关系的方式③的原理相同，在此不赘述。
可选的，在第三配置信息指示关联关系的方式①和方式②中，第六载波的索引包括以下一项或多项：第六载波所在服务小区的索引、用于指示第六载波为所在服务小区的常规上行载波或辅助上行载波的指示信息。例如，如果服务小区中只包括一个上行载波，则第二载波的索引可以通过第六载波所在服务小区的索引来表示。如果服务小区中包括两个上行载波，则第二载波的索引可以通过第六载波所在服务小区的索引+用于指示第六载波为所在服务小区的常规上行载波还是辅助上行载波的指示信息来表示。
在另一种可能的实现中，第三配置信息指示不同载波上同时发送的上行参考信号之间的关联关系的方式具体为：第三配置信息指示不同载波上的上行参考信号资源集之间的关联关系。第三配置信息指示不同载波上的上行参考信号资源集之间的关联关系的具体实现方式可以参见上述第三配置信息指示关联关系的方式①中的描述，在此不赘述。例如，如果第三配置信息指示第五上行参考信号资源集与指示一个第六上行参考信号资源集具有关联关系，则第五上行参考信号资源集与指示一个第六上行参考信号资源集中同时发送的上行参考信号之间具有关联关系。
在又一种可能的实现中，第三配置信息指示不同载波上同时发送的上行参考信号之间的关联关系的方式具体为：第三配置信息指示不同载波之间的关联关系。第三配置信息指示不同载波之间的关联关系的具体实现方式可以参见上述第三配置信息指示关联关系的方式②中的描述，在此不赘述。例如，如果第三配置信息指示第五载波与指示一个第六载波具有关联关系，则第五载波与指示一个第六载波中同时发送的上行参考信号之间具有关联关系。
在一种可能的实现中，第一配置信息、第二配置信息和第三配置信息还用于指示具有关联关系的上行参考信号共天线端口或具有关联关系的上行参考信号具有相位差。例如，协议可以规定具有以下两种关联类型：具有关联关系的上行参考信号共天线端口和具有关联关系的上行参考信号具有相位差。第一网络设备可以根据需求从这两种种关联类型中选择一种关联类型，并通过第一配置信息向终端设备指示选择的关联类型。终端设备接收第一配置信息之后，基于第一配置信息指示的关联类型发送具有关联关系的上行参考信号。第二网络设备接收第三配置信息之后，基于第三配置信息指示的关联类型测量具有关联关系的上行参考信号。基于该可能的实现方式，网络侧能够灵活地向终端设备配置关联关系的类型。
可选的，也可不通过第一配置信息、第二配置信息和第三配置信息来指示关联关系的类型，协议可以直接规定某一种关联类型。例如，协议可以直接规定具有关联关系的上行参考信号共天线端口，或者，协议可以直接规定具有关联关系的上行参考信号具有相位差。
906、终端设备发送具有关联关系的上行参考信号；具有关联关系的上行参考信号共天线端口或具有关联关系的上行参考信号具有相位差。
其中，步骤906的具体实现方式可参见步骤403的具体实现方式，在此不赘述。
907、第二网络设备对具有关联关系的上行参考信号进行测量。
本申请实施例中，第二网络设备接收第三配置信息之后，对第三配置信息配置的具有关联关系的上行参考信号进行测量。第二网络设备可对第三配置信息配置的具有关联关系的上行参考信号进行联合测量。
可选的，第二网络设备具体可通过TRP或RP对具有关联关系的上行参考信号进行联合测量。
可见，基于图9所描述的方法，能够实现大带宽上行参考信号的配置。
请参见图11，图11是本申请实施例提供的一种上行参考信号的关联方法的流程示意图。如图11所示，该上行参考信号的关联方法包括如下步骤1101～步骤1110。图11所示的方法执行主语可以为终端设备、第一网络设备、第二网络设备和定位管理设备，或主语可以为终端设备中的芯片、第一网络设备中的芯片、第二网络设备中的芯片和定位管理设备中的芯片。图11以终端设备、第一网络设备、第二网络设备和定位管理设备为方法的执行主体为例进行说明。其中：
1101、终端设备向第一网络设备上报能力信息，该能力信息用于指示终端设备是否支持同时发送的多个上行参考信号共天线端口，或用于指示终端设备是否支持同时发送的多个上行参考信号具有相位差。
其中，步骤1101可以在步骤1102之前执行，或者在步骤1102之后执行，或者与步骤1102同时执行。
通过向第一网络设备上报终端设备的能力信息，从而第一网络设备可基于终端设备的能力信息准确地确定应该如何为终端设备配置上行参考信号。或者，第一网络设备基于终端设备的能力信息可以进行其他操作。
在一种可能的实现中，能力信息的上报粒度为逐频带上报，或逐频带组上报，或逐频带组内逐频带上报，或逐频带组内逐频带组子集上报。基于该可能的实现方式，能够以较精细地粒度上报终端设备的能力信息。
①逐频带上报。终端设备针对终端设备的每个频带上报一个能力信息。其中，一个频带可包括一个或多个载波。
举例来说，终端设备包括频带1和频带2。终端设备先上报频带1对应的能力信息，再上报频带2对应的能力信息。频带1对应的能力信息用于指示：终端设备在频带1下是否支持同时发送的多个上行参考信号共天线端口，或用于指示终端设备在频带1下是否支持同时发送的多个上行参考信号具有相位差。
频带2对应的能力信息用于指示：终端设备在频带2下是否支持同时发送的多个上行参考信号共天线端口，或用于指示终端设备在频带2下是否支持同时发送的多个上行参考信号具有相位差。
②逐频带组上报。一个频带组可以包括一个或多个频带。假设终端设备具有3个频带组。分别为频带组1、频带组2和频带组3。频带组1包括频带1，频带组2包括频带2，频带组3包括频带1+频带2。终端设备先上报频带组1对应的能力信息，再上报频带组2对应的能力信息，再上报频带组3对应的能力信息。
频带组1对应的能力信息用于指示：终端设备在频带组1下是否支持同时发送的多个上行参考信号共天线端口，或用于指示终端设备在频带组1下是否支持同时发送的多个上行参考信号具有相位差。
频带组2对应的能力信息用于指示：终端设备在频带组2下是否支持同时发送的多个上行参考信号共天线端口，或用于指示终端设备在频带组2下是否支持同时发送的多个上行参考信号具有相位差。
频带组3对应的能力信息用于指示：终端设备在频带组3下是否支持同时发送的多个上行参考信号共天线端口，或用于指示终端设备在频带组3下是否支持同时发送的多个上行参考信号具有相位差。
③逐频带组内逐频带上报。假设终端设备具有3个频带组。分别为频带组1、频带组2和频带组3。频带组1包括频带1，频带组2包括频带2，频带组3包括频带1+频带2。终端设备先上报频带组1中的频带1对应的能力信息，再上报频带组2中的频带2对应的能力信息，再上报频带组3中的频带1对应的能力信息，再上报频带组3中的频带2对应的能力信息。
④逐频带组内逐频带子集上报。假设终端设备具有3个频带组。分别为频带组1、频带组2和频带组3。频带组1包括频带1，频带组2包括频带2，频带组3包括频带1+频带2。频带组1包括一个频带子集，为频带1。频带组2包括1个频带子集，为频带2。频带组3包括3个频带子集，分别为频带1、频带2和频带1+频带2。
终端设备先上报频带组1中的频带1对应的能力信息，再上报频带组2中的频带2对应的能力信息，再上报频带组3中的频带1对应的能力信息，再上报频带组3中的频带2对应的能力信息，再上报频带组3中的频带1+频带2对应的能力信息。
在一种可能的实现中，终端设备还可向定位管理设备上报上述能力信息。能力信息的上报粒度也可以为逐频带上报，或逐频带组上报，或逐频带组内逐频带上报，或逐频带组内逐频带组子集上报。定位管理设备接收终端设备的能力信息之后，就可基于终端设备的能力信息来确定是否向第一网络设备请求生成第一配置信息。
在一种可能的实现中，终端设备不向第一网络设备上报能力信息。终端设备向定位管理设备上报能力信息，由定位管理设备把能力信息转发给第一网络设备。
在另一种可能的实现中，终端设备也可不向第一网络设备和定位管理设备上报能力信息，第一网络设备和定位管理设备可以默认终端设备支持同时发送的多个上行参考信号共天线端口，或用于指示终端设备支持同时发送的多个上行参考信号具有相位差。
1102、定位管理设备向第一网络设备发送第一信息。
其中，该第一信息有以下两种情况：
①第一信息用于请求第一网络设备配置预设带宽的上行参考信号，该预设带宽大于100兆赫兹MHz或预设带宽大于400MHz。
在情况①中，第一网络设备接收到用于请求第一网络设备配置预设带宽的上行参考信号之后，就生成第一配置信息，该第一配置信息用于指示不同载波上同时发送的上行参考信号之间的关联关系。即定位管理设备是隐式地向第一网络设备请求配置不同载波上的同时发送的上行参考信号之间的关联关系。
在一种可能的实现中，该第一信息具体用于请求第一网络设备配置预设频点上的预设带宽的上行参考信号，预设频点属于频率范围1时，该预设带宽大于100兆赫兹MHz，预设频点属于频率范围2时，预设带宽大于400MHz。其中，频率范围1可以是7.1GHz以下，频率范围2可以是24GHz～52.6GHz。
②该第一信息用于请求第一网络设备配置不同载波上的同时发送的上行参考信号之间的关联关系。
在情况②中，定位管理设备能够显示地向第一网络设备请求配置不同载波上的同时发送的上行参考信号之间的关联关系。
在一种可能的实现中，第一信息还用于请求具有关联关系的上行参考信号共天线端口或具有关联关系的上行参考信号具有相位差。基于该可能的实现方式，定位管理设备能够基于用于测量上行参考信号的网络设备的能力信息向第一网络设备推荐应该配置的关联关系的类型，这样有利于第一网络设备合理地配置关联关系的类型。
在一种可能的实现中，定位管理设备也可以不执行步骤1102，由第一网络设备主动生成第一配置信息。
1103、第一网络设备生成第一配置信息，该第一配置信息指示不同载波上同时发送的上行参考信号之间的关联关系；具有关联关系的上行参考信号共天线端口或具有关联关系的上行参考信号具有相位差。
本申请实施例中，第一网络设备可以在接收终端设备的能力信息和定位管理设备发送的第一信息之后，生成第一配置信息。
第一网络设备可以基于终端设备的能力信息生成第一配置信息和第二配置信息。例如，以终端设备逐频带上报能力信息为例。假设终端设备包括频带1和频带2。终端设备先上报频带1对应的能力信息，再上报频带2对应的能力信息。频带1对应的能力信息用于指示：终端设备在频带1下支持同时发送的多个上行参考信号共天线端口。频带2对应的能力信息用于指示：终端设备在频带2下不支持同时发送的多个上行参考信号共天线端口。
频带1下包括载波1和载波2，频带2下包括载波3。第一配置信息可以指示载波1和载波2上同时发送的上行参考信号之间的关联关系。第二配置信息可以指示载波1和载波2上同时发送的上行参考信号之间的关联关系。
1104、第一网络设备向终端设备发送第一配置信息。
1105、第一网络设备生成第二配置信息，该第二配置信息指示不同载波上同时发送的上行参考信号之间的关联关系。
1106、第一网络设备向定位管理设备发送第二配置信息。
1107、定位管理设备向第二网络设备发送第三配置信息，第三配置信息还指示不同载波上同时发送的上行参考信号之间的关联关系。
1108、终端设备发送具有关联关系的上行参考信号。
在一种可能的实现中，终端设备发送具有关联关系的上行参考信号的具体实现方式为：若终端设备支持同时发送的多个上行参考信号共天线端口，或支持同时发送的多个上行参考信号具有相位差，则终端设备在具有关联关系的上行参考信号上发送上行参考信号，并使具有关联关系的上行参考信号共天线端口或具有相位差。也就是说，终端设备需要先判断自己的能力是否支持同时发送的多个上行参考信号共天线端口，或支持同时发送的多个上行参考信号具有相位差。如果支持，则发送具有关联关系的上行参考信号，并使具有关联关系的上行参考信号共天线端口或具有相位差。基于该可能的实现方式，有利于终端设备能够成功地发送上行参考信号。
举例来说，假设终端设备包括频带1和频带2。频带1对应的能力信息用于指示：终端设备在频带1下支持同时发送的多个上行参考信号共天线端口。频带2对应的能力信息用于指示：终端设备在频带2下不支持同时发送的多个上行参考信号共天线端口。频带1下包括载波1和载波2，频带2下包括载波3。第一配置信息指示载波1和载波2上同时发送的上行参考信号之间的关联关系。由于终端设备在频带1下支持同时发送的多个上行参考信号共天线端口，终端设备在载波1和载波2上同时发送上行参考信号时，使在载波1和载波2上同时发送的上行参考信号共天线端口。
1109、第二网络设备对具有关联关系的上行参考信号进行测量。
其中，步骤1105～步骤1109的其他描述可参见上述步骤903～步骤907下的描述，在此不赘述。可选的，本申请实施例全文中，第二网络设备对具有关联关系的上行参考信号进行测量也可以替换为：第二网络设备接收具有关联关系的上行参考信号。
1110、第二网络设备向定位管理设备发送测量结果，测量结果为第二网络设备对具有关联关系的上行参考信号进行测量得到的；测量结果中包括具有关联关系的上行参考信号所在资源集的索引和/或具有关联关系的上行参考信号所在载波的索引。
本申请实施例中，第二网络设备对第三配置信息配置的具有关联关系的上行参考信号进行测量之后，向定位管理设备发送测量结果。
例如，假设测量结果是对SRS资源集11和SRS资源集31中同时发送的SRS联合测量得到的。SRS资源集11属于载波1下的SRS资源集，SRS资源集31属于载波2下的SRS资源集。那么测量结果中可以携带SRS资源集11的索引和SRS资源集31的索引。或者，可携带{载波1的索引、SRS资源集11的索引}和{载波2的索引、SRS资源集31的索引}。
再如，假设测量结果是对载波1和载波2中同时发送的SRS联合测量得到的。那么测量结果中可以携带载波1的索引和载波2的索引。
通过在测量结果中携带具有关联关系的上行参考信号所在资源集的索引和/或具有关联关系的上行参考信号所在载波的索引，有利于定位管理设备确定测量结果是基于哪些上行参考信号资源测量的。
在另一种可能的实现中，终端设备也可以不在测量结果中携带具有关联关系的上行参考信号所在资源集的索引或具有关联关系的上行参考信号所在载波的索引。
