为方便理解，先对本申请实施例所涉及的相关技术及概念进行说明。
在Rel-18SID中包括基于通信网的载波相位定位的相关研究，但是主要集中在仿真，影响载波相位定位的因素分析。具体的流程、方案和相关信息还没有被曝露。
基于载波相位测量(Carrier Phase measurement)的载波相位定位主要应用于GNSS定位，可以解释为距离d与整周数N和载波相位测量Φ相关，即
也就是说，测距可以通过载波相位测量Φ，和求解整周值N来实现。
目前，在一般的信号发送和接收中，对相位的连续性是没有准确的要求的，只有相关(coherent)的上行多输入多输出(UL MIMO)有如下需求，即在一定时间内，如20ms内，相干天线的相位误差(phase error)不超过40度。
终端设备在测量第二定位参考信号，如定位参考信号(Positioning Reference Signal，PRS)时，是在一定时间窗内进行的，该时间窗可以是测量间隙(Measurement Gap，MG)，最长可以为20ms。此外，测量第二定位参考信号的接收相位误差分组(Phase Error Group，PEG)或接收分集(即天线)可能是不同的。这时在不同时间或者不同接收相位误差分组或者接收分集(即天线)下终端设备接收的相位误差可能不同。如图3所示，发送接收点在t0时刻发送的信号的相位误差为e0，终端设备在t1时刻接收到该信号，相位误差为e1，发送接收点在t3时刻发送的信号的相位误差为e3，终端设备在t2时刻接收到该信号，相位误差为e2。进一步，相位误差的引入会使得载波相位测量Φ不准确，同时使得求解的整周数N或最终的终端设备位置不准确。第二定位参考信号为通信设备发送的空口用于定位的参考信号或旁链路用于定位的参考信号。
同理，终端设备发送第一定位参考信号，如探测参考信号(Sounding Reference Signal，SRS)时，可能在不同的时间或者不同的接收相位误差分组或者发送分集(即天线)下，也会有引入不同的发送侧的相位误差的问题。第一定位参考信号可以是终端设备发送的上行用于定位的参考信号或旁链路用于定位的参考信号。
鉴于此，本申请实施例提供了一种载波相位定位方法，第一终端设备向通信设备指示第一定位参考信号与第一相位信息的关联关系，和/或定位测量结果与第二相位信息的关联关系，以辅助通信设备进行定位，可以较好地消除相位误差的影响，使得通信设备能够得到较为准确的载波相位测量，提高定位结果的准确性。

在本申请的一个实施例中，第一相位信息包括相位变化值，第一定位参考信号与第一相位信息的关联关系可以包括第一定位参考信号与相位变化值的关联关系；
其中，第一定位参考信号与相位变化值的关联关系是通过在发送第一定位参考信号时补偿相位变化值表示的；
和/或，第二相位信息包括相位变化值，定位测量结果与第二相位信息的关联关系包括定位测量结果与相位变化值的关联关系；
其中，定位测量结果与相位变化值的关联关系是通过在上报定位测量结果时补偿相位变化值表示的。
在本申请实施例中，第一相位信息可以包括相位变化值，第一终端设备向通信设备指示的第一定位参考信号与第一相位信息的关联关系可以包括第一定位参考信号与相位变化值的关联关系。该第一定位参考信号与相位变化值的关联关系可以是通过在发送第一定位参考信号时补偿相位变化值表示的。即该关联关系可以通过在发送第一定位参考信号时，补偿相位变化值来实现。具体的，第二定位参考信号序列根据相位变化值进行循环移位(cylic shift)可以得到第二定位参考信号补偿序列。
第二相位信息可以包括相位变化值，定位测量结果与第二相位信息的关联关系可以包括定位测量结果与相位变化值的关联关系。定位测量结果与相位变化值的关联关系是通过在上报定位测量结果时补偿相位变化值表示的。即该关联关系可以通过在上报定位测量结果时，补偿相位变化值来实现。
第一相位信息和/或第二相位信息包括相位变化值，第一终端设备向通信设备指示第一定位参考信号与相位变化值的关联关系，和/或定位测量结果与相位变化值的关联关系，方便通信设备根据相应的关联关系，对相位误差进行消除，提高定位结果的准确性。
在本申请的一个实施例中，相位误差分组可以包括发送相位误差分组，第一定位参考信号与第一相位信息的关联关系包括第一定位参考信号与发送相位误差分组的关联关系；
其中，第一定位参考信号与发送相位误差分组的关联关系是通过第一定位参考信号序列和/或第一定位参考信号映射表示的；
和/或，第一定位参考信号与发送相位误差分组的关联关系是动态指示的或者周期性指示的；
和/或，第一定位参考信号与发送相位误差分组的关联关系包括第一定位参考信号的相关标识信息；
和/或，第一定位参考信号与发送相位误差分组的关联关系包括第一定位参考信号与发送相位误差分组的关联关系发生变化时对应的时间戳。
在本申请实施例中，相位误差分组可以包括发送相位误差分组(Tx PEG)，第一定位参考信号与第一相位信息的关联关系可以包括第一定位参考信号与发送相位误差分组的关联关系。
下面从多个角度对第一定位参考信号与发送相位误差分组的关联关系进行说明。
(1)第一定位参考信号与发送相位误差分组的关联关系是通过第一定位参考信号序列和/或第一定位参考信号映射表示的。
比如对于同一个SRS资源，不同周期之间，Tx PEG发生了变化，同一个SRS资源的不同周期上的序列或映射会不同。可以理解为，虽然用于定位的SRS目前只支持1个端口，但关联不同的Tx PEG的SRS可以被看作是多个端口的SRS。
其中，在第一定位参考信号与发送相位误差分组的关联关系通过第一定位参考信号序列表示的情况下，可以通过循环移位区别不同的发送相位误差分组。例如，不同的循环移位对应不同的发送相位误差分组，不同的循环移位区别不同的发送相位误差分组与发送相位误差分组的数量有关。
在一种具体的实施方式中，通信设备可以指示或协议约定一组循环移位集合，关联不同发送相位误差分组的第一定位参考信号可以对应各自的循环移位值，生成第一定位参考信号序列。比如，PEG0关联SRS时，第一终端设备可以使用PEG0对应的循环移位生成SRS序列并发送；PEG1关联SRS时，第一终端设备可以使用PEG1对应的循环移位生成SRS序列并发送。
在第一定位参考信号与发送相位误差分组的关联关系通过第一定位参考信号映射表示的情况下，通过频分多路复用(Frequency-division multiplexing，FDM)区别不同的相位误差分组。通过频分多路复用的方式区别不同的发送相位误差分组与发送相位误差分组的数量有关。
在一种具体的实施方式中，关联不同发送相位误差分组的第一定位参考信号可以映射到同一个符号(symbol)的不同的资源元素/资源粒子(Resource Element，RE)上，通过频分多路复用进行分区。如，PEG1关联SRS时，第一终端设备可以使用PEG1对应的时频位置发送SRS。
当第一终端设备支持的发送相位误差分组的数量较多时，可以结合第一定位参考信号序列以及第一定位参考信号映射联合区分多个发送相位误差分组。
在本申请实施例中，第一定位参考信号与发送相位误差分组的关联关系是否通过第一定位参考信号序列和/或第一定位参考信号映射表示，可以是根据通信设备的功能开关指示确定的。
通信设备可以指示是否开启“用序列和/或映射方式表示第一定位参考信号与发送相位误差分组的关联关系”功能，比如通过开关指示。
在一种示例中，当服务gNB收到位置服务器的请求，比如要求(实时)获得SRS与Tx PEG的关联关系。服务gNB即可指示第一终端设备将相应功能开关开启。第一终端设备根据功能开关开启指示可以通过序列和/或映射方式指示SRS与Tx PEG的关联关系。
在一种示例中，当第二终端设备要求(实时)获得SL-SRS与Tx PEG的关联关系时，第二终端设备可指示第一终端设备将相应功能开关开启。第一终端设备根据功能开关开启指示可以通过序列和/或映射方式指示SL-SRS与Tx PEG的关联关系。
在第一终端设备只支持/关联一个Tx PEG的场景中，或者对定位精度要求不高的场景中，相应功能开关可以设置为“关”或者缺省指示。
另外，第一定位参考信号与发送相位误差分组的关联关系是通过第一定位参考信号序列表示、或者通过第一定位参考信号映射表示、或者通过第一定位参考信号序列和第一定位参考信号映射联合表示，是根据通信设备的指示确定的，或者是协议约定的，或者是第一终端设备选择的。
即使用“序列方式”，还是“映射方式”，还是“序列+映射”方式表示第一定位参考信号与发送相位误差分组的关联关系，可以由通信设备指示、协议约定或第一终端设备自行选择。
(2)第一定位参考信号与发送相位误差分组的关联关系是动态指示的。
动态指示可以包括基于事件触发的动态指示，和/或非周期的动态指示。
其中，基于事件触发的动态指示为在第一定位参考信号关联的发送相位误差分组发生变化时触发的动态指示。即第一定位参考信号传输过程中，若第一定位参考信号关联的发送相位误差分组发生了变化，则可以触发第一终端设备发送相应关联关系指示，指示第一定位参考信号与发送相位误差分组的关联关系或关联关系的变化。可选的，事件触发指示前，第一终端设备至少指示一次第一定位参考信号与发送相位误差分组的关联关系。
以第一定位参考信号为SRS为例，具体指示方式可以包括以下之一：
指示目标信令之前最近的一个SRS实例(SRS instance)的SRS与Tx PEG的关联关系发生了变化，持续生效时间至下一次信令前两个SRS实例；
指示目标信令之后到下一次信令之前这段时间的SRS与Tx PEG的关联关系。在这段时间内，SRS与Tx PEG的关联关系不变。
目标信令是指当前指示第一定位参考信号与发送相位误差分组的关联关系的信 令。
对于非周期的动态指示，可以通过以下示例理解。
若第一终端设备上报时刻为t，第一终端设备上报t之前某个时间窗内SRS实例中SRS与Tx PEG的关联关系。时间窗可以由t之前最近的N个SRS实例构成。N为正整数，可以是协议约定/通信设备指示/第一终端设备选择的。时间t可以由通信设备指示，如下行控制信息(Downlink Control Information，DCI)信令+偏移(offset)指示。DCI信令可以是触发非周期第一定位参考信号的DCI。
(3)第一定位参考信号与发送相位误差分组的关联关系是周期性指示的。
周期性指示是第一终端设备周期性地报告第一定位参考信号与发送相位误差分组的关联关系，可以适用于周期第一定位参考信号或半持续第一定位参考信号。对于半持续第一定位参考信号，周期性指示的生效时间可以为MAC层的控制单元(MAC Control Element，MAC CE)信令生效的时间。
周期性指示的第一定位参考信号与发送相位误差分组的关联关系是相邻周期间隔时间之间的(包含至少一个第一定位参考信号实例中)第一定位参考信号与发送相位误差分组的关联关系。
第一定位参考信号与发送相位误差分组的关联关系的周期性指示的周期可以是通信设备指示的，或者是协议约定的，或者是第一终端设备选择的。这里的周期可以是具体的周期还可以是周期偏移。
第一定位参考信号与发送相位误差分组的关联关系的周期性指示的周期与第一定位参考信号的发送周期相关，和/或与通信设备的第一定位参考信号测量结果的上报周期相关。
比如，该周期为SRS周期的M1倍，M1为正整数，或者该周期为gNB上报第一定位参考信号测量结果周期的M2倍，M2为正整数。
在本申请的一种具体实施方式中，第一定位参考信号与发送相位误差分组的关联关系的周期性指示可以是在满足第一条件时进行的，其中，第一条件包括：
相对于前一次周期上报的第一定位参考信号与发送相位误差分组的关联关系发生变化；
和/或，相对于前一次周期上报的时间大于时间阈值。
在本申请实施例中，可以对第一定位参考信号与发送相位误差分组的关联关系或者上报时间进行监测，在目标周期，如果相对于前一次周期上报的第一定位参考信号与发送相位误差分组的关联关系发生变化时，或者相对于前一次周期上报的时间大于时间阈值，则认为满足第一条件，可以进行第一定位参考信号与发送相位误差分组的关联关系的周期性指示，在目标周期上报第一定位参考信号与发送相位误差分组的关联关系。
即只有在满足第一条件时进行第一定位参考信号与发送相位误差分组的关联关 系的指示，这样有助于节省传输资源。
第一终端设备在第一定位参考信号与发送相位误差分组的关联关系的周期性指示中，如果目标周期的第一定位参考信号与发送相位误差分组的关联关系与目标周期的前一周期或者第一个周期的第一定位参考信号与发送相位误差分组的关联关系相同，则将目标周期的第一定位参考信号与发送相位误差分组的关联关系指示为无变化，或者缺省指示。
也就是说，当某个周期的第一定位参考信号与发送相位误差分组的关系与前一周期，或者第一个周期的第一定位参考信号与发送相位误差分组的关联关系一致时，可以通过指示无变化，如通过1bit指示无变化，或者缺省指示。
可选的，在往返(Round Trip Technology，RTT)定位方法，或Multi-RTT定位方法中，第一终端设备周期性指示的第一定位参考信号与发送相位误差分组的关联关系，可以包含在第一终端设备收发时差(UE Rx-Tx time difference)的测量上报中。
在通信设备为网络侧设备的情况下，第一定位参考信号与发送相位误差分组的关联关系的动态指示或周期性指示的指示信令可以包括以下至少一种：
上行链路控制信息(Uplink Control Information，UCI)信令；
MAC层的控制单元(MAC Control Element，MAC CE)信令；
无线资源控制(Radio Resource Control，RRC)信令；
定位协议信令，如LTE定位协议(LTE Positioning Protocol，LPP)信令。
在通信设备为第二终端设备的情况下，第一定位参考信号与发送相位误差分组的关联关系的动态指示或周期性指示的指示信令可以包括以下至少一种：
直连通信接口无线资源控制(PC5-RRC)信令；
直连通信接口MAC层的控制单元(PC5-MAC CE)信令；
直连通信接口旁链路(PC5-SL)定位协议信令。
通过上述信令可以对第一定位参考信号与发送相位误差分组的关联关系进行显示指示。
(4)第一定位参考信号与发送相位误差分组的关联关系包括第一定位参考信号的相关标识信息。
其中，第一定位参考信号的相关标识信息包括以下至少一项：
第一定位参考信号的资源集标识，如SRS resource set ID；
第一定位参考信号的资源标识，如SRS resource ID；
服务小区标识，如serving cell ID；
载波标识，如carrier标识；
带宽部分(Bandwidth Part，BWP)标识，如BWP ID；
频带指示(band indicator)，如绝对频域指示信息、band指示信息、频率范围FR1或FR2指示信息；
第一定位参考信号实例对应的时间戳(time stamp)；
第一定位参考信号实例的标识；
第一定位参考信号所在载波和/或带宽部分的频域位置信息，该频域位置信息包括但不限于载波和/或带宽部分的起始位置、带宽、子载波、PointA等，该频域位置信息还可以是可识别第一定位参考信号所在载波和/或带宽部分的其他信息；
第一定位参考信号的端口标识，如SRS Port ID；
第一定位参考信号关联的发送相位误差分组标识，如SRS Tx PEG ID。
(5)第一定位参考信号与发送相位误差分组的关联关系包括第一定位参考信号与发送相位误差分组的关联关系发生变化时对应的时间戳。即包含第一定位参考信号与发送相位误差分组的关联关系发生变化的时间对应的时间戳。
以上在多个角度对第一定位参考信号与发送相位误差分组的关联关系进行了说明，基于第一定位参考信号与发送相位误差分组的关联关系有助于通信设备进行定位计算，提高定位结果准确性。
需要说明的是，以上对第一定位参考信号与发送相位误差分组的关联关系的相关说明同样适用于第一定位参考信号与相位变化值和/或相位变化阈值的关联关系。
在本申请的一个实施例中，第一相位信息是相对于参考第一定位参考信号的相位变化信息，或者是相对于参考上行时间的相位变化信息，或者是相对于定位测量结果的相位变化信息；
和/或，
第二相位信息是相对于参考发送接收点的相位变化信息。
在本申请实施例中，第一相位信息和/或第二相位信息可以是相对相位信息。
与第一定位参考信号有关联关系的第一相位信息可以是相对于参考第一定位参考信号的相位变化信息，如是相对于参考SRS的相位变化信息，或者是相对于参考上行时间的相位变化信息，或者是相对于定位测量结果的相位变化信息。
参考第一定位参考信号可以是目标第一定位参考信号的前一个第一定位参考信号，或者是指定的一个第一定位参考信号，如通信设备指定的，或者第一终端设备指定的一个第一定位参考信号。目标第一定位参考信号为当前发送的或将要发送的第一定位参考信号。
与定位测量结果有关联关系的第二相位信息可以是相对于参考发送接收点的相位变化信息，即相对于参考TRP(PRS resource)的相位变化信息。其中，所述相对于参考发送接收点的相位变化信息包括以下至少之一：相对于接收定位参考信号的相位变化信息，相对于发送定位参考信号的相位变化信息，相对于参考下行时间的相位变化信息，相对于参考的TRP接收定位参考信号的相位变化信息，相对于参考TRP的接收的参考定位参考信号的相位变化信息。
在本申请的一个实施例中，相位误差分组可以包括接收相位误差分组，定位测 量结果与第二相位信息的关联关系包括定位测量结果与接收相位误差分组的关联关系。
在本申请实施例中，相位误差分组可以包括接收相位误差分组(Rx PEG)，定位测量结果与第二相位信息的关联关系可以包括定位测量结果与接收相位误差分组的关联关系。
在这种情况下，第一终端设备向通信设备指示定位测量结果与第二相位信息的关联关系，可以包括以下至少之一：
第一终端设备向通信设备指示目标定位测量结果关联的多个接收相位误差分组；
第一终端设备向通信设备上报多个接收相位误差分组分别关联的定位测量结果；
第一终端设备在不同的时间戳对应的定位测量结果中指示该定位测量结果与接收相位误差分组的关系。
为方便理解，现逐一对以上各项进行说明。
(1)第一终端设备向通信设备指示目标定位测量结果关联的多个接收相位误差分组。
其中，目标定位测量结果可以是当前所针对的定位测量结果，如可以是某个PRS resource下的定位测量结果，一个定位测量结果可以关联一个或多个接收相位误差分组，第一终端设备可以向通信设备指示目标定位测量结果关联的一个或多个接收相位误差分组。目标定位测量结果关联的接收相位误差分组的数量可以是通信设备指示的，或者协议约定的，或者第一终端设备选择的。
目标定位测量结果与多个接收相位误差分组有关，表示同一时刻，第一终端设备使用了多个接收面板(Rx panel)接收了同一个第二定位参考信号资源，如PRS resource；或者同一个第二定位参考信号资源，如PRS resource进行了重复发送，第一终端设备进行了接收波束扫频(Rx beam sweeping)，接收波束扫频时发生了接收面板的切换。
第一终端设备向通信设备指示目标定位测量结果关联的一个或多个接收相位误差分组，包括以下至少之一：
第一终端设备指示目标定位测量结果关联的一个或多个接收相位误差分组分别关联的接收波束索引；第一终端设备可以指示一个或多个接收相位误差分组分别关联的接收波束索引(Rx beam Index)，表示某个接收相位误差分组关联的定位测量结果也与该接收波束索引有关。可选的，这里接收波束索引可以是绝对的接收波束索引，还可以不是绝对的接收波束索引，只要能用于区分接收相位误差分组关联的定位测量结果是由不同的接收波束测量获得即可。可选的，一个或多个接收相位误差分组可以只关联一个接收波束或者与接收波束无关，缺省指示；以第二定位参考 信号为PRS为例，对于某个PRS resource，第一终端设备上报该PRS resource的定位测量结果。该定位测量结果按照P个接收相位误差分组分成P组。对于其中某组定位测量结果，除了关联某个接收相位误差分组，还关联一个或多个接收波束，第一终端设备可以上报对应的接收波束索引。当关联多个接收波束时，该组定位测量结果是由多个接收波束的联合测量所得；当关联一个接收波束时，该组定位测量结果是由某个接收波束测量所得，当然，该某个接收波束可以是在多个接收波束中选择的最好的接收波束；
第一终端设备指示目标定位测量结果关联的一个或多个接收相位误差分组是由多个接收波束扫描获得，或者是同时测量第二定位参考信号资源，如PRS resource获得；
第一终端设备指示目标定位测量结果的时间戳；即第一终端设备可以指示一个或多个接收相位误差分组关联的目标定位测量结果的时间戳，表示不同的接收相位误差分组关联的定位测量结果可以从不同的时间戳测量获得。这里，时间戳可以表示不同周期的测量，或者同一个周期不同时间的测量；
第一终端设备指示目标定位测量结果关联的多个接收相位误差分组之间的相位误差；第一终端设备可以选择或指示以某个接收相位误差分组为参考，其他每个接收相位误差分组将参考的接收相位误差分组作为被减数做差。可选的，参考的接收相位误差分组可以是所有径(path)中，最早的径对应的接收相位误差分组；
第一终端设备根据通信设备的指示或者协议约定，在目标定位测量结果关联多个接收相位误差分组，和/或不同接收相位误差分组之间的相位误差小于或等于第一阈值时，上报目标测量结果与接收相位误差分组没有关联关系；即根据通信设备的指示或协议约定，若实际某个定位测量结果关联的多个接收相位误差分组，和/或不同接收相位误差分组之间的相位误差大于或等于第一阈值，则上报的定位测量结果不关联接收相位误差分组，可以认为这种情况下定位测量结果与接收相位误差分组进行关联没有意义；
第一终端设备指示目标定位测量结果关联的一个或多个接收相位误差分组对应的地址解析协议(Address Resolution Protocol，ARP)标识，如ARP ID。
(2)第一终端设备向通信设备上报多个接收相位误差分组分别关联的定位测量结果。
多个接收相位误差分组关联的定位测量结果可能相同或不同，第一终端设备可以向通信设备上报多个接收相位误差分组分别关联的定位测量结果。
(3)第一终端设备在不同的时间戳对应的定位测量结果中指示该定位测量结果与接收相位误差分组的关系。
如果该定位测量结果与接收相位误差分组的关系与前一次指示的，或者第一次指示的相应关系一致，则第一终端设备可以用1bit指示无变化，或者缺省指示。
第一终端设备向通信设备指示定位测量结果与第二相位信息的关联关系可以通过上述多种方式进行指示，以便于通信设备基于该关联关系进行相位误差消除，提高定位结果准确性。
在本申请的一个实施例中，在第一终端设备向通信设备指示定位测量结果与第二相位信息的关联关系之前，还包括：
第一终端设备从通信设备接收第一指示信息；
其中，第一指示信息包括以下至少之一：
对第二定位参考信号资源进行重复测量的指示信息；
跨不同的第二定位参考信号周期进行接收相位误差分组的扫频的指示信息；
限制扫频所针对的接收相位误差分组的指示信息；
跨接收相位误差分组扫频所针对的接收相位误差分组的指示信息；
上报不同的接收相位误差分组关联的定位测量结果的指示信息；
上报无法按照相关指示信息进行扫频或上报定位测量结果的理由的指示信息；
同时测量第二定位参考信号的接收相位误差分组的数量的指示信息。
在本申请实施例中，第一终端设备可以从通信设备接收第一指示信息，根据该第一指示信息可以使用一个或多个接收相位误差分组对第二定位参考信号进行测量，得到定位测量结果，以向通信设备指示定位测量结果与第二相位信息的关联关系。如，通信设备可以指示第一终端设备对某个PRS resource测量时，通过R个接收相位误差分组的方式，测量该PRS resource。
第一指示信息可以包括以下至少之一：
1)对第二定位参考信号资源进行重复测量的指示信息。即指示了对第二定位参考信号资源，如PRS resource，或PRS resource set进行重复(repetition)测量。进一步的，还可以指示重复测量的次数大于某个次数门限；
2)跨不同的第二定位参考信号周期进行接收相位误差分组的扫频的指示信息。即指示第一终端设备跨不同的第二定位参考信号周期，如PRS周期，或称为PRS instance，进行接收相位误差分组扫频(Rx PEG sweep)。比如，对于同一个PRS resource，或同一个PRS resource set，多个周期产生一次测量，多个周期上，可能进行波束扫频(beam sweep)。可选的，可以指示第一终端设备总的接收相位误差分组扫频中接收相位误差分组的个数，以及每个第二定位参考信号周期中接收相位误差分组扫频的接收相位误差分组的个数。可选的，可以指示接收相位误差分组因子，用于指示第一终端设备可以(最多)使用多少个第二定位参考信号周期完成一次接收相位误差分组扫频；其中，接收相位误差分组扫频可以理解为，不同的接收波束在多个接收相位误差分组上进行扫频，这样有助于第一终端设备计算接收相位误差分组之间的差；
3)限制扫频所针对的接收相位误差分组的指示信息。具体的，可以在接收相位 误差分组扫频指示中限制只在某几个接收相位误差分组上进行扫频；
4)跨接收相位误差分组扫频所针对的接收相位误差分组的指示信息；具体的，可以在接收相位误差分组扫频指示中指示第一终端设备跨哪几个接收相位误差分组扫频；
5)上报不同的接收相位误差分组关联的定位测量结果的指示信息；即指示第一终端设备可以上报不同接收相位误差分组关联的定位测量结果；
6)上报无法按照相关指示信息进行扫频或上报定位测量结果的理由的指示信息；即指示第一终端设备在其无法按照通信设备的相关指示信息进行扫频或者上报定位测量结果时，上报理由。比如，某个接收相位误差分组关联的定位测量结果低于某个质量门限；
7)同时测量第二定位参考信号的接收相位误差分组的数量的指示信息。即指示第一终端设备可以使用X个接收相位误差分组对第二定位参考信号进行测量。在指示X时，通信设备可以先确定第一终端设备是否可以同时使用Y个接收相位误差分组对第二定位参考信号进行测量，如对PRS resource，或PRS resource set进行测量。Y>＝X。
第一终端设备从通信设备接收上述至少一项第一指示信息，可以基于该第一指示信息对第二定位参考信号进行测量，得到定位测量结果，将定位测量结果与第二相位信息的关联关系指示给通信设备，以辅助通信设备进行定位。
在本申请的一个实施例中，该方法还可以包括以下步骤：
第一终端设备向通信设备指示目标第二定位参考信号资源关联的多个接收相位误差分组，和/或多个接收相位误差分组的定位测量结果，和/或多个接收波束索引；
第一终端设备从通信设备接收第二指示信息，第二指示信息用于指示将目标第二定位参考信号资源作为其他第二定位参考信号资源的接收相位误差分组参考资源。
在本申请实施例中，第一终端设备可以先向通信设备指示目标第二定位参考信号资源关联的多个接收相位误差分组，和/或多个接收相位误差分组的定位测量结果，和/或多个接收波束索引。如对于某个PRS resource，第一终端设备可以先指示该PRS关联的Q个接收相位误差分组和/或Q个接收相位误差分组的定位测量结果和/或多个接收波束索引(Rx beam index)。
通信设备可以发送第二指示信息，用于指示将目标第二定位参考信号资源作为其他第二定位参考信号资源的接收相位误差分组参考资源。
第一终端设备从通信设备接收到第二指示信息后，即可按照第二指示信息确定接收相位误差分组参考资源。
如，通信设备可以指示将上述的PRS resource作为其他PRS resource的“Rx PEG参考resource”。可选的，上报定位测量结果的参考PRS resource，或PRS resource set 可以作为Rx PEG的参考resource。可选的，上报定位测量结果的参考Rx PEG关联的PRS resource，或PRS resource set可以作为Rx PEG的参考resource。
需要说明的是，若定位测量结果为载波相位测量差，则需要关联至少两个Rx PEG：
参考resource，或参考resource set的Rx PEG 1，以及目标resource，或目标resource set的Rx PEG 2。
在本申请的一个实施例中，相位误差分组可以包括发送相位误差分组，定位测量结果与第二相位信息的关联关系可以包括定位测量结果与发送相位误差分组的关联关系。
一种情况下，定位测量结果包括终端接收时差(UE Rx-Tx time difference)时，关联关系可以包括以下至少之一：
终端接收时差(UE Rx-Tx time difference)与发送和接收的PEG(RxTx PEG)的关联关系；
终端接收时差(UE Rx-Tx time difference)与发送PEG(Tx PEG)的关联关系；
其中，若包含Tx PEG，则还可以包括Tx PEG与第一定位参考信号的关联关系。
在本申请的一个实施例中，该方法还可以包括以下步骤：
第一终端设备向通信设备指示是否已对定位测量结果进行相位误差补偿。
在本申请实施例中，第一终端设备可以根据自身能力或者通信设备的指示，确定是否对定位测量结果进行相位误差补偿。第一终端设备向通信设备指示定位测量结果与第二相位信息的关联关系，还可以向通信设备指示是否已对定位测量结果进行相位误差补偿。
如果第一终端设备向通信设备指示已对定位测量结果进行相位误差补偿，则通信设备可以直接使用定位测量结果进行定位计算，不需要再进行相位误差消除等操作，如果第一终端设备向通信设备指示未对定位测量结果进行相位误差补偿，则通信设备可以根据相应的关联关系，进行相位误差消除后再进行定位计算。方便通信设备采取不同措施以利用第一终端设备指示的关联关系。
在本申请的一个实施例中，第一终端设备在已对定位测量结果进行相位误差补偿的情况下，向通信设备指示以下至少之一：
定位测量结果与接收相位误差分组没有关联关系；
定位测量结果与一个接收相位误差分组的关联关系；
相位误差补偿方式；
相位误差补偿的可信度。
在本申请实施例中，第一终端设备在已对定位测量结果进行相位误差补偿的情况下，可以向通信设备指示定位测量结果与接收相位误差分组没有关联关系。即当第一终端设备指示对定位测量结果的相位误差进行了补偿，第一终端设备可以指示 定位测量结果与接收相位误差分组的关系为无。
第一终端设备还可以向通信设备指示定位测量结果与一个接收相位误差分组的关联关系。即第一终端设备只指示定位测量结果与一个接收相位误差分组的关联关系，该接收相位误差分组可以是协议约定的或通信设备指示的或第一终端设备选择的默认的接收相位误差分组。
第一终端设备还可以指示相位误差补偿方式。如内部补偿，或者第一终端设备根据多个接收相位误差分组关联的不同定位测量结果进行的计算和补偿。
第一终端设备还可以指示相位误差补偿的可信度(confidence)。
通信设备根据第一终端设备指示的上述信息可以确定进一步操作，如是直接利用定位测量结果进行定位计算还是在进一步进行相位误差消除操作后再进行定位计算。
需要说明的是，第一终端设备还可以根据通信设备的指示或协议约定或第一终端设备选择，在满足一定条件后，对定位测量结果进行相位误差补偿、或上报相位误差，或上报定位测量结果与多个相位误差分组的关联关系。
在本申请的一个实施例中，该方法还可以包括以下步骤：
第一终端设备根据指示测量第一测量窗内的第二定位参考信号，在第一时间内定位测量结果的相位误差小于或等于第二阈值，第一测量窗包括第一时间；
或者，第一终端设备根据配置发送第一定位参考信号，在第二时间内，第一定位参考信号的相位误差小于或等于第三阈值。
在本申请实施例中，第一测量窗包括第一时间，第一时间可以为第一测量窗，或者为特定时间，如20ms，或者为设定数量的时隙。在第一时间内定位测量结果的相位误差小于或等于第二阈值。
第二时间可以与第一时间相同或不同，在第二时间内，第一定位参考信号的相位误差小于或等于第三阈值。
对定位测量结果的相位误差或第一定位参考信号的相位误差进行限定，可以减少相位误差对相位误差测量带来的影响。
在本申请的一个实施例中，该方法还可以包括以下步骤：

测量第二定位参考信号和/或发送第一定位参考信号关联的相位误差分组的数量；

发送接收点发送第二定位参考信号与第三相位信息的关联关系。
在本申请实施例中，通信设备可以向第一终端设备发送第三指示信息，第三指 示信息可以用于指示以下至少一项：
1)测量第二定位参考信号和/或发送第一定位参考信号关联的相位误差分组的数量。即第一终端设备在指示定位测量结果和/或第一定位参考信号与相位误差分组的关联关系前，可以接收通信设备的指示，该指示是用于指示第一终端设备测量第二定位参考信号，如PRS或发送第一定位参考信号，如SRS时可关联的相位误差分组的数量。
在一种具体示例中，第一终端设备支持4个发送相位误差分组(Tx PEG)，但通信设备指示第一终端设备在发送SRS时，只能关联或激活2个Tx PEG。比如，第一终端设备支持Tx PEG 0、Tx PEG 1、Tx PEG 2、Tx PEG 3，通信设备指示第一终端设备只能关联2个Tx PEG，如Tx PEG 0和Tx PEG 2，那么，第一终端设备在发送SRS时，只能关联这2个Tx PEG，而不是其支持的4个Tx PEG。
2)第一终端设备是否计算和/或上报接收相位误差分组之间的相位差值。即第一终端设备在指示定位测量结果和/或第一定位参考信号与相位误差分组的关联关系前，可以接收通信设备的指示，该指示用于指示第一终端设备是否可计算和/或上报相位误差分组之间的相位差值。
3)第一终端设备是否在定位测量结果中补偿相位误差分组的相位误差。即第一终端设备在指示定位测量结果和/或第一定位参考信号与相位误差分组的关联关系前，可以接收通信设备的指示，该指示用于指示第一终端设备是否可在定位测量结果中补偿相位误差分组，如接收相位误差分组的相位误差。
4)发送接收点发送第二定位参考信号与第三相位信息的关联关系。即第一终端设备被指示TRP侧发送的第二定位参考信号，如PRS与第三相位信息的关联关系。如，不同的TRP之间的相位差值，或TRP Tx PEG，相同TRP不同第二定位参考信号资源之间的相位差值。
第一终端设备从通信设备接收上述至少一项第三指示信息，可以基于第三指示信息进行相应操作。
在本申请的一个实施例中，关联相同的相位误差分组的第一定位参考信号的相位变化阈值小于或等于第四阈值；
和/或，关联相同的相位误差分组的定位测量结果的相位变化阈值小于或等于第五阈值。
在本申请实施例中，不同第一定位参考信号可能关联相同的相位误差分组，关联相同的相位误差分组的第一定位参考信号的相位变化阈值可以小于或等于第四阈值，以使得关联相同的相位误差分组的第一定位参考信号的相位变化较小。
同样，不同定位测量结果可能关联相同的相位误差分组，关联相同相位误差分组的定位测量结果的相位变化阈值可以小于或等于第五阈值，以使得关联相同相位误差分组的定位测量结果的相位变化较小。

换言之，校准能力可以是第一终端设备不支持任何面板的发送相位误差和/或接收相位误差的校准。
校准能力还可以是第一终端设备支持单面板的发送相位误差和/或接收相位误差的校准，即第一终端设备有能力校准同一个面板的收发相位误差，或者把该面板的收发相位误差限制在一个范围内。对于接收信号及发送信号都在同一个面板，如panel1，或者接收信号及发送信号都在同一个面板，如panel 2，第一终端设备可能可以保证收发相位误差相同。比如2 Rx panel与2 Tx panel的组合，此时可能只需关联3个RxTx TEG，而非4组{Rx TEG,Tx TEG}。
校准能力还可以是第一终端设备支持单面板的接收相位误差的校准。
