其中，t 1是UE从TRP接收到的下行定位参考信号(Downlink Positioning Reference Signal，DL PRS)的时间，t 2是探测参考信号(Sounding Reference Signal，SRS)的发送时间，t 3是从TRP接收到SRS的时间，t 0是DL PRS的发送时间。
UE和TRP之间的RTT值可以计算为：
RTT meas＝(Rx-Tx) TRP+(Rx-Tx) UE＝t 3-t 0+t 1-t 2＝t 1-t 0+t 3-t 2
但是，以上所有发送和接收时间都是在基带中获得的，它们由实际的传 播延迟和Rx/Tx timing error组成，如下式：
RTT meas＝2*T prop+(e 0+e 3)+(e 1+e 2)＝2*T prop+e TRP+e UE
其中T prop是UE与TRP之间的实际传播延迟，e 0是TRP的发送时间误差(Tx timing error)，e 3是TRP的接收时间误差(Rx timing error)，e 1是UE的Rx timing error，e 2是UE的Tx timing error，e TRP是TRP侧包括e 0和e 3总的时间误差(timing error)，e UE是UE侧包括e 1和e 2的timing error。
由于受到Rx/Tx timing的影响，基于RTT的定位会受到影响。同理，其他基于时间的定位方法也会有影响。
因此，如何消除Rx/Tx timing error，提高定位准确性成为目前定位技术中亟待解决的问题。

下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描 述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequenc9Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequenc9Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequenc9-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。

Tx时间误差(Tx timing error):从信号传输的角度来看，从在基带生成数字信号的时间到从Tx天线发送RF信号的时间会有时间延迟。为了支持定位，UE/TRP可以对DL PRS/UL SRS信号的传输实施Tx时间延迟(Tx time dela9)的内部校准/补偿。校准后剩余的Tx时间延迟或未校准的Tx时间延迟定义为Tx时间误差。从上图看，UE侧的Tx timing error，可以理解为是浅蓝色部分从BB到Ant的时间。
Rx时间误差(Rx timing error):从信号接收的角度来看，从Rx天线接收RF信号到基带处理会有时间延迟。为了支持定位，UE/TRP可以在进行测量上报前，对DL PRS/UL SRS的测量结果执行Rx时间延迟(Rx time dela9)的内部校准/补偿。校准后剩余的Rx时间延迟或未校准的Rx时间延迟定义为Rx时间误差。从上图看，UE侧的Rx timing error，可以理解为是浅蓝色部分从Ant到BB的时间。
UE Tx时间误差组(UE Tx‘timing error group’(UE Tx TEG))：UE Tx TEG与用于定位的一个或多个UL SRS资源的传输相关联，这些资源的Tx时间误差在一定范围内。从讨论看，认为同一个Tx panel发送的SRS，可以关联同一UE Tx TEG。
TRP Tx时间误差组(TRP Tx‘timing error group’(TRP Tx TEG))：TRP Tx TEG与一个或多个DL PRS资源的传输相关联，这些资源的Tx时间误差在一定范围内。从讨论看，可认为同一个Tx panel发送的PRS，可以关联同一TRP Tx TEG。

下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的定位处理方法进行详细地说明。
如图3所示，本申请实施例的定位处理方法，包括：
步骤301，终端发送第一指示信息；
其中，所述第一指示信息用于指示以下至少一项：
上行定位参考信号与时间误差组(Timing Error Group，TEG)的关联关系；
定位测量结果与TEG的关联关系。
其中，上行定位参考信号包含但不限于以下至少之一：SRS for positioning,SRS for MIMO,物理随机接入信道(Physical Random Access Channel，PRACH)等等。定位测量结果包含但不限于以下至少之一：下行参考信号时间差(DownLink Reference Signal Time Difference，DL RSTD)，UE Rx-Tx time difference测量结果，下行离开角(DownLink Angle of Departure，DL-AOD)相关的测量结果。
这样，终端通过向第一网络侧设备发送该第一指示信息，使得该第一网络侧设备能够获知上行定位参考信号与TEG的关联关系，和/或，定位测量结果与TEG的关联关系，在定位时基于该关联关系消除Rx/Tx timing error，达到提高定位准确性的目的。这里，第一网络侧设备可以是位置服务器。
比如下行定位中，同一个UE会收到来自多个TRP的定位参考信号(Positioning Reference Signals，PRS)，并得到多个下行链路(DownLink，DL)测量结果。如果多个DL测量结果可以关联相同的UE Rx时间误差组(Timing Error Group，TEG)，则在处理多个DL测量结果时可以做差，以消除相同的UE Rx timing error。那么UE在向第一网络侧设备(如位置服务器(Location Management Function，LMF)上报DL测量结果时，可以指示DL测量结果与UE Rx TEG的关联关系，以辅助第一网络侧设备完成进一步的定位计算。
同理，上行定位时，UE发送信道探测用参考信号(Sounding Reference Signal，SRS)时，可以指示SRS与Tx TEG的关联关系。下行+上行定位(如RTT定位)，UE会上报收发时间差(Rx-Tx time difference)的测量结果，可以提供测量结果与Tx TEG和/或Rx TEG的关联关系，或与RxTx TEG的关联关系。
除了UE之外，在TRP侧，TRP也可以指示TRP侧TEG(Rx TEG和/或Tx TEG)与测量结果，和/或，TEG(Rx TEG和/或Tx TEG)与参考信号的关联关系。
该实施例中，TEG可以是Tx TEG,Rx TEG,RxTx TEG,或{Rx TEG,Tx TEG}。而关联关系可以用关联的TEG ID表示，或者相同的TEG的SRS或定位测量结果分为1组，或者其他方式。
具体的，上行定位参考信号与TEG的关联关系包含以下至少之一：
上行定位参考信号与UE Tx TEG的关联关系；
上行定位参考信号与UE RxTx TEG的关联关系；
上行定位参考信号与UE{Rx TEG,Tx TEG}的关联关系；
具体的，定位测量结果与TEG的关联关系包含以下至少之一：
定位测量结果与UE Rx TEG的关联关系；
定位测量结果与UE RxTx TEG的关联关系；
定位测量结果与UE{Rx TEG,Tx TEG}的关联关系。
可选地，所述方法还包括：
所述终端获取第二指示信息，所述第二指示信息用于指示发送所述第一 指示信息的信令方式，所述信令方式包含以下之一：
所述终端发送所述第一指示信息至第一网络侧设备；
所述终端发送所述第一指示信息至第二网络侧设备，再由所述第二网络侧设备发送至所述第一网络侧设备。
可选的，上述‘所述终端发送所述第一指示信息至第二网络侧设备，再由所述第二网络侧设备发送至所述第一网络侧设备’还可以表示为‘所述终端发送所述第一指示信息至第二网络侧设备’。因为对于终端来说，只需关心第一指示信息发送给哪个网络侧设备，而无需关心发送给网络侧设备后网络侧设备的行为。
如此，终端由该第二指示信息指示的方式发送第一指示信息至第一网络侧设备。具体地，终端可以直接发送该第一指示信息至第一网络侧设备；还可以发送该第一指示信息至第二网络侧设备，由第二网络侧设备发送至第一网络侧设备。其中，该第一网络侧设备是位置服务器，如LMF，第二网络侧设备是基站，包括服务gNB和邻区gNB中至少之一。可选的，终端直接发送该第一指示信息至第一网络侧设备，可以通过LPP消息发送；终端发送第一指示信息至第二网络侧设备，可以包含但不限于通过RRC,MAC CE,UCI至少之一发送。可选的，终端使用哪个消息发送第一指示至第一网络侧设备或第二网络侧设备，可以由网络指示，协议约定，UE选择等至少一种方式确定。
其中，终端在第一指示信息用于指示上行定位参考信号与时间误差组TEG的关联关系；定位测量结果与TEG的关联关系中至少一项时，接收该第二指示信息。
而该第二指示信息可以是第一网络侧设备发送的，也可以是第二网络侧设备发送的。
此外，可选地，所述终端发送第一指示信息之前，还包括：
所述终端获取TEG级别信息；
所述终端根据所述TEG级别信息，确定所述第一指示信息。
如此，终端在获取TEG级别信息后，根据该TEG级别信息来确定有效的第一指示信息。
这里，TEG级别信息也可称为TEG校准级别，获取方式可以包括以下至少一种：由终端自主确定、协议约定或网络(预)配置。
可选地，所述TEG级别信息包括至少一组映射关系，每组映射关系包括以下至少一项：
TEG级别标识；
与TEG级别对应的时间误差门限；
与TEG级别对应的时间误差差门限；
与TEG级别对应的定位精度要求；
与TEG级别对应的定位参考信号配置信息。
其中，TEG级别标识表示TEG的级别，如:L1。
其中，时间误差(timing error)门限可以是timing error的范围，timing error的边界，或timing error的最大值和/或最小值。当然，timing error门限还可以是timing error统计特性门限，包含但不限于均值、方差、协方差至少之一。类似于timing error门限，时间误差差(timing error difference)门限可以是timing error difference的范围，timing error difference的边界，或timing error difference的最大值和/或最小值，同样的还可以是timing error difference统计特性门限。故，2次传输的timing error/timing error difference小于(或不超过，或满足)对应的门限可以认为2次传输的timing error属于1个TEG。以timing error difference为例，在已知(或粗略已知)timing error difference的情况下，2次传输的timing error difference小于(或不超过)这个门限(即timing error difference门限)可以认为2次传输的timing error属于1个TEG。如，Rx timing error difference小于这个门限的测量结果可以处于1个Rx TEG；Tx timing error difference小于这个门限的上行参考信号可以处于1个Tx TEG；Rx+Tx timing error difference小于这个门限的测量结果和/或上行参考信号可以处于1个RxTx TEG。
其中，定位精度要求包含精度水平，置信度至少之一。而定位精度要求与TEG级别标识的映射包含一一对应，一对多，或多对一至少一种。
其中，定位参考信号配置信息包含但不限于以下至少之一：带宽，如PRS bandwidth；重复，如PRS repetition；子载波间隔。
这样，TEG级别信息可实现为：L1级的timing error difference的门限为[x1]ns；L2级的timing error difference的门限为[x2]ns。或者，TEG级别信息实现为：对于TEG级别为L1对应定位精度要求为[y1]m。
例如，协议约定或网络(预)配置TEG级别信息如下表1所示，以时间误差差为例：
表1
Figure PCTCN2022091462-appb-000001
在表1中，一行为一组映射关系。当精度要求小于[0.2m]时，对应的Timing error difference margin幅度要小于[2ns]，对应于TEG级别L0；
当精度要求小于[0.5m]时，对应的Timing error difference margin要小于[5ns]，对应于TEG级别L1。
另外，该实施例中，可选地，所述方法还包括：
所述终端发送TEG能力信息；
其中，所述TEG能力信息包括指示一组映射关系，每组映射关系包括以下至少一项：
TEG级别标识；
与TEG级别对应的时间误差门限；
与TEG级别对应的时间误差差门限；
与TEG级别对应的定位精度要求；
与TEG级别对应的定位参考信号配置信息；
与TEG级别对应的时间误差的统计特性参数；
与TEG级别对应的时间误差差的统计特性参数；
与TEG级别对应的TEG个数。
这里，TEG级别标识、时间误差门限、时间误差差门限、定位精度要求、定位参考信号配置信息如上所述，在此不再赘述。而与TEG级别对应的TEG个数，即对于同一TEG级别可存在的TEG个数。统计特性参数包括但不限于以下之一：均值、方差、协方差、统计分布类型等等。
例如，TEG能力信息如下表2所示，以时间误差差为例：
表2
Figure PCTCN2022091462-appb-000002
表2中，一行为一组映射关系。由表2内容，对于L0级来说，UE不支持；
对于L1级来说，只有2次传输timing error difference小于[20ns]时，才能属于1个TEG，UE可识别的TEG个数为4个；
对于L2级来说，只有2次传输timing error difference小于[100ns]时，才能属于1个TEG，UE可识别的TEG个数为2个；
对于L3级来说，只有2次传输timing error difference小于[100ns]时，才能属于1个TEG，UE可识别的TEG个数为1个。
其中，如果协议约定或网络(预)配置与TEG级别对应的时间误差差门限，TEG能力信息的每组映射关系中可不包括该项。当然，对于L0级来说，UE不支持，则TEG级别为L0的一组映射关系在UE能力中可以缺省(即表2中可删除该行)。
可选的，当UE不支持‘获取timing error difference’时，UE不提供表2所示的映射关系。
还应该知道的是，该TEG能力信息可包含在终端能力信息，在终端上报 自身能力信息时，与其他信息一起发送。
该实施例中，可选地，所述方法还包括：
所述终端从第一网络侧设备接收请求信息，所述请求信息用于请求所述终端提供所述第一指示信息或TEG能力信息。
也就是说，终端是基于第一网络侧设备的请求，发送第一指示信息或TEG能力信息。这里，第一网络侧设备的请求可以是由第一网络侧设备直接请求，也可以是由第一网络侧设备间接请求。其中，直接请求即第一网络侧设备直接发送请求信息；间接请求即第一网络侧设备发送请求消息至第二网络侧设备，再由第二网络侧设备发送至终端。应该了解的是，间接请求还可以等效为第二网络侧设备请求。
可选地，所述请求信息包括以下至少一项：
请求标识；
TEG级别标识；
目标时间误差门限；
目标时间误差差门限；
定位精度要求；
TEG能力信息请求。
这里，请求标识用于表示该请求信息的用途，如请求终端提供第一指示信息，或者请求终端提供TEG能力信息，而请求标识也可由请求指令实现。TEG级别标识可用于请求终端提供对应的TEG级别下，上行定位参考信号与TEG的关联关系，和/或，定位测量结果与TEG的关联关系；或者，请求终端提供低于(或不高于)或高于(或不低于)对应的TEG级别下，上行定位参考信号与TEG的关联关系，和/或，定位测量结果与TEG的关联关系。当然，TEG级别标识可用于请求终端提供对应的TEG级别的时间误差门限、时间误差差门限、定位精度要求、定位参考信号配置信息中的至少一种。目标时间误差门限是终端确定TEG时的时间误差门限，目标时间误差差门限是终端确定TEG时的时间误差差门限，而目标时间误差门限的具体实现如上所述 的时间误差门限，目标时间误差差门限的具体实现如上所述的时间误差差门限，在此不再赘述。定位精度要求包含精度水平，置信度至少之一，用于请求终端提供在该定位精度要求下对应的第一指示信息，辅助终端确定TEG的分组。当该请求用于请求TEG能力时，所述TEG级别标识、目标时间误差门限、目标时间误差差门限或定位精度要求，可以分别用于请求该TEG级别标识、目标时间误差门限、目标时间误差差门限或定位精度要求下的终端的TEG能力，如终端是否支持TEG和/或支持的TEG的数目和/或时间误差(差)的统计特性。
可选地，所述请求信息通过以下至少一项发送：
长期演进定位协议LPP消息；
新空口定位协议NRPPa消息；
无线资源控制RRC消息；
媒体接入控制单元MAC CE消息；
下行控制信息DCI；
广播消息。
下面，举例说明请求信息的发送方式：Case1：请求信息可以通过LPP消息直接由位置服务器LMF发送至UE。Case2：请求信息可以通过NRPPa由位置服务器LMF发送至服务gNB，再由服务gNB通过信令如RRC，MAC CE，DCI或广播消息至少之一发送至UE。
可选地，若定位精度要求较低，如低于预设定位精度门限，请求信息可以缺省；和/或，若网络侧设备希望请求的TEG级别下UE仅支持1个TEG，或者UE仅支持1个TEG，或者UE不支持TEG，请求信息可以缺省；和/或，若定位参考信号(下行定位参考信号或上行定位参考信号带宽)的配置满足某个门限，请求信息可缺省。其中，定位参考信号的配置包含但不限于以下至少之一：带宽，定位参考信号重复，定位参考信号子载波间隔，定位参考信号周期等等。比如定位参考信号的配置为定位参考信号带宽时，当定位参考信号的带宽小于某个门限，请求信息可以缺省。所述门限可以根据网络指 示，协议约定或终端选择至少一种方式确定。
不同的定位精度要求下，UE提供的TEG信息可能不同。比如：当定位精度要求不高时，UE可以不提供TEG的第一指示信息，或者UE提供较宽松校准下的TEG的第一指示信息；当定位精度要求较高时，UE需要提供较严格校准下的TEG的第一指示信息。为了避免请求消息可能未包括定位精度要求，终端无法提供适用的第一指示信息，因此，可选地，所述终端发送第一指示信息之前，还包括：
所述终端接收第一网络侧设备的定位精度要求。
这里，该定位精度要求用于辅助终端上报该第一指示信息。该定位精度要求可包含在位置服务质量(Quality of Service，Qos)指示中，Qos指示包含定位精度要求、时延要和QoS类别(LCS QoS class)中的至少之一。故，接收到的定位精度要求可作为TEG级别信息，用于确定第一指示信息。可选的，终端接收第一网络侧设备的定位精度要求适用于下行定位方法(如DL-TDOA定位方法)，上行定位方法(如UL-TDOA定位方法)，下行+上行定位方法(如Multi-RTT定位方法)至少一种。
可选的，若定位精度要求较低，如低于预设定位精度门限，终端可不提供第一指示信息；和/或，若网络侧设备希望请求的TEG级别下UE仅支持1个TEG，或者UE仅支持1个TEG，或者UE不支持TEG，终端可不提供第一指示信息；和/或，若定位参考信号(下行定位参考信号或上行定位参考信号带宽)的配置满足某个门限，终端可不提供第一指示信息。其中，定位参考信号的配置包含但不限于以下至少之一：带宽，定位参考信号重复，定位参考信号子载波间隔，定位参考信号周期等等。比如定位参考信号的配置为定位参考信号带宽时，当定位参考信号的带宽小于某个门限，请求信息可以缺省。所述门限可以根据网络指示，协议约定或终端选择至少一种方式确定。
可选地，所述第一指示信息还用于指示TEG所属的TEG级别。
这样，在第一指示信息指示上行定位参考信号与TEG的关联关系，和/或定位测量结果与TEG的关联关系时，对于该关联关系中的TEG，指示其所 属的TEG级别。例如，请求信息包括一TEG级别标识，向终端请求不低于该TEG级别标识对应级别的TEG的第一指示信息时，第一指示信息中会指示TEG所属的TEG级别，如终端选择满足要求的某个TEG级别，提供对应的第一指示信息。
该实施例中，可选地，所述第一指示信息用于指示定位测量结果与TEG的关联关系，且所述定位测量结果为收发时间差时，所述收发时间差关联的TEG与一个或多个上行定位参考信号资源对应。
这里，收发时间差关联的TEG，即UE RxTx TEG或{Rx TEG,Tx TEG}。当定位测量结果为收发时间差(Rx-Tx time difference)，终端发送第一指示信息指示定位测量结果与UE RxTx TEG或{Rx TEG,Tx TEG}的关联关系。这里，UE RxTx TEG与一个或多个上行定位参考信号资源对应，或者{Rx TEG,Tx TEG}中的Tx TEG与一个或多个上行定位参考信号资源对应。
可选地，所述一个或多个上行定位参考信号资源包括以下至少一项：
距离当前测量时刻最近的上行定位参考信号传输时机的资源；
预设的一个或多个上行定位参考信号传输时机的资源；
第一时间窗内的一个或多个上行定位参考信号传输时机的资源。
其中，当前测量时刻是对应Rx-Tx time difference测量的时刻，或者当前测量时刻对应Rx-Tx time difference测量，或者对应Rx-Tx time difference测量实例instance，或者对应Rx-Tx time difference测量关联的PRS资源集实例PRS resource set instance，或者对应Rx-Tx time difference测量中Rx time或Tx time的时刻。
其中，传输时机(transmission occasion)，也可用其它方式如传输周期、传输实例(transmission instance)等等。以SRS为例，表示为SRS transmission occasion，SRS occasion，SRS transmission instance，SRS instance等等。
可选地，距离当前测量最近的上行定位参考信号传输时机，可以在当前测量时刻之前，确定距离当前测量最近的上行定位参考信号传输时机；也可以在当前测量时刻之后，确定距离当前测量最近的上行定位参考信号传输时 机；还可以不受限于当前测量时刻的前后，这样，该距离当前测量最近的上行定位参考信号传输时机可以处于当前测量时刻之前，也可以处于当前测量时刻之后。
可选地，预设的一个或多个上行定位参考信号传输时机的资源是网络指示、协议约定、终端选择中至少一种方式确定的。
可选地，所述第一时间窗可以包含该当前测量时刻。即，该第一时间窗包含该Rx-Tx time difference测量。
可选的，该第一时间窗可以由协议约定、网络指示、终端选择中至少一种方式确定。
可选地，所述第一时间窗内的一个或多个上行定位参考信号传输时机，包含以下至少之一：
所述第一时间窗内距离当前测量时刻最近的一个或多个上行定位参考信号传输时机；
所述第一时间窗内指定的上行定位参考信号传输时机；
所述第一时间窗内任意的上行定位参考信号传输时机。
其中，在该第一时间窗内距离当前测量时刻最近的一个或多个上行定位参考信号传输时机，可以受限于当前测量时刻之前或当前测量时刻之后，也可以不受限于当前测量时刻的前后，同上述内容，在此不再赘述。
可选的，上述的第一时间窗与时间窗A一致(或者相同，或相关)。其中，时间窗A描述如下：gNB或者TRP的进行上行测量时(如测量上行定位参考信号)，网络侧设备(如LMF)会配置时间窗A，gNB或TRP上报时间窗A内的测量结果(测量结果如RTOA,UL RSRP,and/or gNB Rx-Tx time difference measurements等等)。其中，时间窗A包含至少1个gNB/TRP测量实例(gNB/TRP measurement instance)，每个测量实例包含至少1个上行定位参考信号测量时机(如SRS measurement time occasions)。
该实施例中，可选地，所述第一指示信息还包含TEG的一致性指示信息，所述一致性指示信息表示不同时刻下的相同的TEG标识下的TEG信息是否 一致。
例如，该一致性指示信息可以为：不同时刻下的相同的TEG标识下的TEG信息发生了变化，或者相同的TEG标识下的TEG信息不能保持一致性。
这里，不同时刻下的相同的TEG ID对应的TEG信息发生了变化(即相同的TEG标识下的TEG对应的timing error的范围/大小发生了变化)，网络不能假设不同时刻下，相同的TEG ID对应相同的TEG。或者说，不同时刻下的相同TEG ID对应的TEG的timing error发生了变化(或者timing error的大小，范围和统计特性中的至少一者发生了变化)。比如由于1小时前的TEG与1个小时后的TEG不能看做同一个TEG，即使TEG ID相同。而不同时刻可以是不同的测量instance,测量occasion，或者不同上行定位参考信号Instance,occasion。或者是相邻的测量instance,测量occasion，或者相邻的上行定位参考信号Instance,occasion。
可选的，所述TEG的一致性指示信息也可以用其他指示信息指示，其中其他指示信息可不同与第一指示信息。可选的，其他指示信息可以在第一指示信息之前或之后。
该实施例中，可选地，在所述TEG信息的一致性保持的时间内，所述第一指示信息还包含以下至少一项：
定位测量结果与TEG的关联关系的变化信息；
上行定位参考信号与TEG的关联关系的变化信息。
这里，以SRS为例，变化信息可以实现为：2个SRS instance中一个或多个SRS resource关联Tx TEG发生了变化，如Tx TEG ID发生了变化。在SRS occasion X，SRS resource 0关联Tx TEG0，SRS resource1关联Tx TEG1；在SRS occasion X+1，SRS关联的Tx TEG发生了变化，比如SRS resource 0变为关联Tx TEG1,SRS resource1变为关联Tx TEG0。这种TEG变化是可能由于UE切换面板(panel)导致。
而TEG信息的一致性保持的时间，是不同时刻下的相同的TEG标识下的TEG信息一致的有效时间。
也就是说，在TEG信息的一致性保持的时间内，终端指示定位测量结果与TEG的关联关系的变化信息，和/或，上行定位参考信号与TEG的关联关系的变化信息。或者说，TEG信息的一致性保持的时间内，终端指示TEG的关联关系的变化才有效。或者说，终端指示TEG关联关系的变化的有效时间等于或者不超过TEG信息的一致性保持的时间。
可选的，所述TEG的关联关系的变化信息也可以用其他指示信息指示，其中，其他指示信息可不同与第一指示信息。可选的，其他指示信息可以在第一指示信息之前或之后。
可选地，所述第一指示信息用于指示定位测量结果与TEG的关联关系，且所述定位测量结果是基于定位参考信号测量所得时，所述第一指示信息指示一个TRP下多个定位参考信号资源的测量结果与至少一个TEG的关联关系；其中，所述一个TRP下多个定位参考信号资源的测量结果与至少一个TEG的关联关系中，每个TEG至少关联1个定位参考信号资源的测量结果。
这里，该定位测量结果是基于定位参考信号测量所得，定位参考信号可以是下行PRS。
可选地，所述多个定位参考信号资源满足以下条件至少之一：
属于相同的定位参考信号资源集；
属于相同的定位频率层；
属于第二时间窗的范围内；
时间上的距离小于距离门限。
这里，第二时间窗是由网络指示、协议约定、终端选择中至少之一确定，比如多个定位参考信号资源位于相同的测量时间窗。时间上的距离小于距离门限，是指该多个定位参考信号资源(如PRS资源)中，最前的PRS资源与最后的PRS资源距离小于该距离门限。
