示例性的，UE1和UE2可以均为协同驾驶的车载终端。
在上述场景下，UE1和UE2之间可以交互信息，从而完成定位。例如，UE1可以通过与UE2之间交互信息，从而完成对UE2的定位。例如，UE1通过对UE2的定位，可使得UE1明确获知UE2的方位，如UE1可以避开UE2等。又例如，当UE1需要超车时，该UE1就可以对UE2进行定位。
图1b是本申请实施例提供的另一种通信系统的示意图。如图1b所示，该通信系统可以包括至少一个接入网设备以及至少一个终端设备。

一般的，UE中可能会有多个天线面板(panel)(或者，panel也可以指的是一个或一组天线面板)。对于车辆来说，各个panel之间的距离可能会达到米级，因此，当车辆之间的距离较近时，就无法忽略各个panel测量得到的位置相关信息的差异性。如果将多个panel测量得到的信息进行混淆，会降低定位的精度。
鉴于此，本申请提供一种定位方法及装置，通过第一指示信息，可使得第一终端设备明确获知可使得第一终端设备明确获知第一时间差对应第一接收时刻，该第一接收时刻与第一端口关联，以及第二时间差对应第二接收时刻，该第二接收时刻与第二端口关联。从而改善了第二终端设备反馈给第一终端设备的时间差信息存在模糊的问题，以及有效改善了第一终端设备无法正确区分第二终端设备反馈的时间差的问题。第一终端设备可以明确区分出了各个时间差，提高了第一终端设备区分时间差的效率以及准确率。即可准确地区分出不同参考信号对应的数据(如不同参考信号对应的接收时刻或时间差等)，从而对不同panel测量的数据进行准确地区分。进一步的，还可以利用panel之间的相对位置信息等，进一步对定位结果进行优化，提高定位的精度和准确度。

可理解，本申请示出的参考信号，可以是单端口的参考信号，也可以是多端口的参考信号。该多端口的参考信号也可以理解为是具有不同端口标识的同一个参考信号。以下将以参考信号是多端口的参考信号或单端口的参考信号的不同角度为例说明本申请提供的定位方法。可理解，本申请示出的参考信号可以为用于定位的参考信号。例如，第一参考信号、第二参考信号、第三参考信号、第四参考信号或第五参考信号可以为用于定位的参考信号。例如， 该用于定位的参考信号包括定位参考信号(positioning reference signals，PRS)或探测参考信号(sounding reference signal，SRS)等，本申请不作限定。可理解，本申请对于UE如何获知参考信号的标识不作限定。示例性的，UE B接收到第一参考信号后，通过解析该第一参考信号，可以获得该第一参考信号的标识。例如，当第一参考信号为多端口时，该第一参考信号的标识包括第三端口的标识和第四端口的标识(如也可以称为多端口的参考信号的ID，或者，PRS的port ID等)。又例如，当第一参考信号为单端口时，UE B则可以向UE A指示该第一参考信号的标识(如也可以称为第一参考信号的ID，如PRS的ID)。
另外，对于UE来说，由于其可能会包括不止一个panel，如可能包括一个panel，也可能包括两个panel，也可能包括三个panel等，因此，以下将结合panel的数量说明本申请提供的定位方法。可理解，本申请示出的panel不仅可以称为天线面板，还可以称为天线端口。示例性的，该panel可以指的是一个或一组天线面板，或者，指的是一个或一组天线端口等，本申请对于panel的具体定义不作限定。
图2是本申请实施例提供的一种定位方法的流程示意图，如图2所示，该方法包括：
201、UE A发送第一参考信号。
示例性的，UE A在时刻T A_Tx发送第一参考信号。示例性的，UE A在时刻T A_Tx向UE B发送第一参考信号，相应的，UE B接收该第一参考信号。可理解，时刻T A_Tx在附图中是以T A_Tx为例示出的，同时，时刻T B_Tx在附图中是以T B_Tx为例示出的，不应将其理解为对本申请实施例的限定。
可选的，UE A可以包括一个天线端口，UE B包括两个天线端口(如包括第一天线端口和第二天线端口)。可理解，这里所示的一个天线端口和两个天线端口仅为示例，该UE A还可以包括更多数量的天线端口，以及该UE B也可以包括更多数量的天线端口，本申请实施例对此不作限定。
例如，该UE B的两个天线端口可以均为收发端口，也可以称为收发合一的端口。也就是说，该UE B的两个天线端口都可以既用于接收信号，又用于发送信号。又如，当UE A包括一个天线端口时，该天线端口可以是收发端口。又例如，当UE A包括两个天线端口时，该两个天线端口中的一个天线端口可以是发送端口，另一个天线端口可以是接收端口。又例如，UE A还可以包括两个天线端口，该两个天线端口是收发端口。本申请实施例对于UE A中所包括的天线端口的具体类型不作限定。
示例性的，图3a示出的是UE A包括一个天线端口(为收发端口)，UE B包括两个天线端口(都是收发端口)。图3b示出的是UE A包括一个发送端口，一个接收端口，UE B包括两个天线端口(都是收发端口)。如图3a和图3b所示，UE B可以分别在时刻T B1_1和时刻T B2_1接收第一参考信号。如时刻T B1_1可以理解为第一参考信号的第一接收时刻，时刻T B2_1可以理解为第一参考信号的第二接收时刻。可选的，图3a和图3b所示的第一参考信号还可以理解为单端口的参考信号。
图3c示出的是UE A包括两个天线端口(都是收发端口)，UE B包括两个天线端口(都是收发端口)。
如图3c所示，可选的，UE A发送的两个参考信号可以为多端口的参考信号。例如，UE A发送的第一参考信号包括第三端口和第四端口。可选的，UE B可以在时刻T B1_1接收第三端口的第一参考信号，以及时刻T B2_1接收第三端口的第一参考信号。UE B可以在时刻T B1_2接收第四端口的第一参考信号，以及时刻T B2_2接收第四端口的第一参考信号。该情况下，时刻T B1_1(如第一接收时刻)可以理解为第三端口的第一参考信号的接收时刻，时刻T B2_1(如第二接收时刻)可以理解为第三端口的第一参考信号的接收时刻。时刻T B1_2(如第三接收时刻)可以理解为第四端口的第一参考信号的接收时刻。时刻T B2_2(如第四接收时刻)可以理解为 第四端口的第一参考信号的接收时刻。
如图3c所示，可选的，UE A发送的第一参考信号还可以理解为单端口的参考信号，该情况下，UE A还可以发送第三参考信号。可选的，UE B可以在时刻T B1_1接收第一参考信号，以及时刻T B2_1接收第一参考信号。UE B可以在时刻T B1_2接收第三参考信号，以及时刻T B2_2接收第三参考信号。该情况下，时刻T B1_1可以理解为第一参考信号的接收时刻，时刻T B2_1可以理解为第一参考信号的第二接收时刻。时刻T B1_2可以理解为第三参考信号的第三接收时刻。时刻T B2_2可以理解为第三参考信号的第四接收时刻。
202、UE A接收第二参考信号，该第二参考信号包括第一端口和第二端口。
该第二参考信号可以理解为包括第一端口的标识和第二端口的标识的参考信号。
示例性的，UE B在时刻T B_Tx向UE A发送第二参考信号，该UE A接收该第二参考信号。
如图3a和图3b所示，UE A可以在时刻T A1_1接收第一端口的第二参考信号，以及在时刻T A1_2接收第二端口的第二参考信号。如图3c所示，UE A还可以在时刻T A2_1接收第一端口的第二参考信号，以及在时刻T A2_2接收第二端口的第二参考信号。
203、UE A接收第一指示信息。
对于第一指示信息，本申请实施例提供了以下实现方式：
实现方式一、
在一种可能的实现方式中，该第一指示信息用于指示第一时间差和第二时间差。
示例性的，该第一时间差为第二参考信号的发送时刻(如时刻T B_Tx)与第一参考信号的第一接收时刻(如时刻T B1_1)的时间差，即第一时间差可以为T B_Tx-T B1_1。第二时间差为第二参考信号的发送时刻与第一参考信号的第二接收时刻(时刻T B2_1)的时间差，即第二时间差可以为T B_Tx-T B2_1。
本申请实施例中，第一接收时刻与第一端口关联，第二接收时刻与第二端口关联。也就是说，第一接收时刻是与第二参考信号的第一端口关联，而第二接收时刻是与第二参考信号的第二端口关联。
示例性的，第一接收时刻与第一端口关联可以理解为：第一端口的第二参考信号是由UE B的第一天线端口(如panel 1)发送的，第一接收时刻是为该第一天线端口接收第一参考信号的时刻。如图3a所示，UE B通过该panel 1向UE A发送第一端口的第二参考信号，以及UE B通过panel 1接收第一参考信号，UE B通过panel 1接收第一参考信号的时刻即为第一接收时刻。也就是说，通过将第一接收时刻与第一端口关联，可使得UE A明确获知第一时间差是与第一端口关联的，从而在UE A接收到第一端口的第二参考信号之后，便可以根据该UE A接收第一端口的第二参考信号的接收时刻、第一时间差以及第一参考信号的发送时刻对UE B进行定位。又或者说，如果UE A不能获知第一接收时刻与第一端口关联的信息，则该UE A就无法准确将第一时间差与第一端口的第二参考信号的接收时刻关联。例如，UE A可能会根据第一时间差、第二端口的第二参考信号的接收时刻以及第一参考信号的发送时刻对UE B进行定位，从而UE B的定位会不准确，导致对UE B的定位精度低下。可理解，本申请实施例关于关联的说明，同样适用于下文示出的关联的说明，如不仅适用于第二接收时刻与第二端口关联的说明，同样适用于第三接收时刻与第一端口的标识关联的说明，以及第四接收时刻与第二端口的标识关联的说明。
示例性的，第二接收时刻与第二端口关联可以理解为：第二端口的第二参考信号是UE B的第二天线端口(如panel 2)发送的，第二接收时刻是为该第二天线端口接收第一参考信号的时刻。如图3a所示，UE B通过该panel 2向UE A发送第二端口的第二参考信号，以及UE B通过panel 2接收第一参考信号，UE B通过panel 2接收第一参考信号的时刻即为第二接收时刻。可理解，关于第二接收时刻与第二端口关联的具体说明可以参考上述第一接收时刻与 第一端口关联的介绍，这里不再一一详述。
可选的，第一指示信息还用于指示第一时间差与第一端口的标识关联，和/或，第二时间差与第二端口的标识关联。也就是说，第一指示信息不仅用于指示第一时间差，还用于指示该第一时间差与第一端口的标识关联。以及该第一指示信息不仅用于指示第二时间差，还用于指示该第二时间差与第二端口的标识关联。示例性的，第一时间差与第一端口的标识关联，包括：第一端口的第二参考信号是由UE B的第一天线端口(如panel 1)发送的，第一接收时刻是为该第一天线端口接收第一参考信号的时刻。可理解，下文所示的第一指示信息包括第一端口的第二参考信号的标识，可以理解为：该第一指示信息中包括了第一端口的第二参考信号的标识所对应的索引，或者该第一指示信息中包括了第一端口第二参考信号的标识所对应的编码信息等，本申请实施例对此不作限定。可理解，本申请实施例示出的第一端口的第二参考信号的标识也可以称为第一端口的第二参考信号的ID。关于第二端口的第二参考信号的标识的说明，可以参考第一端口的第二参考信号的标识的描述，这里不再赘述。
通过指示上述信息，可使得UE A明确获知第一时间差对应第一端口的第二参考信号的接收时刻，以及第二时间差对应第二端口的第二参考信号的接收时刻，从而改善了UE B由于反馈给UE A的时间差信息存在模糊，而导致UE A无法正确区分UE B反馈的时间信息来自于UE B的哪个panel的问题。进而，UE A明确区分出了各个时间差信息，提高了UE A区分时间差的效率以及准确率。
可选的，第一指示信息包括第一时间差的指示信息以及与第一时间差关联的第一端口的标识的指示信息，和/或，第二时间差的指示信息以及与第二时间差关联的第二端口的标识的指示信息。也就是说，UE B可以通过明式指示地方式向UE A指示第一时间差是与第一端口的标识关联的，以及第二时间差是与第二端口的标识关联的。
示例性的，如以图3a或图3b为例，则第一指示信息可以如表1所示。
表1
T B_Tx-T B1_1 第一端口的标识
T B_Tx-T B2_1 第二端口的标识
可选的，第一端口的标识小于第二端口的标识，第一指示信息还用于指示第一时间差与第一端口的标识关联，和/或，第二时间差与第二端口的标识关联，包括：第一时间差与第二时间差按照预先设置的规则排列。示例性的，当第一端口的标识小于第二端口的标识时，第一指示信息中所包括的第一时间差的指示信息和第二时间差的指示信息可以按照预先设置的规则排列。例如，第一指示信息中可以依次包括第一时间差的指示信息和第二时间差的指示信息。又例如，第一指示信息中可以依次包括第二时间差的指示信息和第一时间差的指示信息。可理解，本申请实施例对于该预先设置的规则不作限定。例如，该预先设置的规则可以由协议设置，或者，也可以由网络设备(如接入网设备)设置，或者，也可以由UE A和UE B协商确定等，本申请实施例对此不作限定。
示例性的，如以图3a或图3b为例，则第一指示信息可以如表2所示。
表2
T B_Tx-T B1_1
T B_Tx-T B2_1
示例性的，如以图3a或图3b为例，则第一指示信息可以如表3所示。

可理解，关于表2或表3所示的第一时间差和第二时间差的排列方式仅为示例。
实现方式二、
在另一种可能的实现方式中，该第一指示信息还用于指示第三时间差和第四时间差。
可选的，在第一参考信号包括第三端口和第四端口的情况下，上述第一接收时刻和上述第二接收时刻可以为第三端口的第一参考信号的接收时刻。
该情况下，第三时间差为第二参考信号的发送时刻与第三接收时刻(如T B1_2)的时间差，即第三时间差可以为T B_Tx-T B1_2。第四时间差为第二参考信号的发送时刻与第四接收时刻(如T B2_2)的时间差，即第四时间差可以为T B_Tx-T B2_2。如第三接收时刻和第四接收时刻为第四端口的第一参考信号的接收时刻。
可选的，第一指示信息还用于指示第三时间差与第一端口的标识关联，和/或，第四时间差与第二端口的标识关联。
可选的，第一指示信息还用于指示第一时间差与第三端口的标识关联，和/或，第二时间差与第三端口的标识关联。
可选的，第一指示信息还用于指示第三时间差与第四端口的标识关联，和/或，第四时间差与第四端口的标识关联。
也就是说，第一指示信息用于指示第一时间差、第二时间差、第三时间差和第四时间差。可选的，该第一指示信息还用于指示以下至少一项：第一时间差与第一端口的标识关联、第一时间差与第三端口的标识关联、第二时间差与第二端口的标识关联、第二时间差与第三端口的标识关联、第三时间差与第一端口的标识关联、第三时间差与第四端口的标识关联、第四时间差与第二端口的标识关联、第四时间差与第四端口的标识关联。示例性的，上述时间差不仅可以关联UE B接收到的第一参考信号的端口的标识，还可以关联UE B发送的第二参考信号的端口的标识。
示例性的，如以图3c为例，则第一指示信息可以如表4所示。
表4

T B_Tx-T B2_1 第二端口的标识 第三端口的标识
T B_Tx-T B1_2 第一端口的标识 第四端口的标识

可理解，表4仅为一种示例，对于第一指示信息如何指示上述关联关系，本申请实施例不作限定。示例性的，第一指示信息可以包括：第一时间差的指示信息、与第一时间差关联的第一端口的标识的指示信息、与第一时间差关联的第三端口的标识的指示信息；第二时间差的指示信息、与第二时间差关联的第二端口的标识的指示信息、与第二时间差关联的第三端口的标识的指示信息；第三时间差的指示信息、与第三时间差关联的第一端口的标识的指示信息、与第三时间差关联的第四端口的标识的指示信息；第四时间差的指示信息、与第四时间差关联的第二端口的标识的指示信息、与第四时间差关联的第四端口的标识的指示信息。
示例性的，当第一端口的标识小于第二端口的标识时，第一指示信息的内容可以如表5或如表6所示。
表5
T B_Tx-T B1_1
T B_Tx-T B1_2
T B_Tx-T B2_1
T B_Tx-T B2_2
可理解，表5所示的第一指示信息还可以理解为：以第一端口的标识和第二端口的标识为第一优先级，以第三端口的标识和第四端口的标识为第二优先级。当第一端口的标识小于第二端口的标识时，且第三端口的标识小于第四端口的标识时，第一时间差的指示信息、第二时间差的指示信息、第三时间差的指示信息、第四时间差的指示信息按照预先设置的规则排列。

可理解，表4至表6是本申请实施例提供的示例，对于第一指示信息中的具体内容或格式，本申请实施例不作限定。
UE A在获得上述第一指示信息之后，可以根据该第一指示信息获得第一时间差、第二时间差、第三时间差与第四时间差分别是与哪个参考信号关联的。从而可以获知接收第三端口的第一参考信号的天线端口，也用于发送第一端口的第二参考信号，即UE A可以获得第三端口的第一参考信号与第一端口的第二参考信号是通过同一个panel传输的。进而，UE A可以明确区分各个时间差，提高了区分的效率以及准确度。

通过指示上述信息，可使得UE A明确获知第一时间差对应第一端口的第二参考信号的接收时刻，以及第二时间差对应第二端口的第二参考信号的接收时刻，从而改善了UE B由于反馈给UE A的时间差信息存在模糊，而导致UE A无法正确区分UE B反馈的时间信息来自于UE B的哪个panel的问题。进而，UE A明确区分出了各个时间差信息，提高了UE A区分时间差的效率以及准确率。
可理解，图2所示的方法是以UE B发送的参考信号都是多端口的参考信号，以下将以UE B发送单端口的参考信号为例说明本申请实施例提供的方法。
图5是本申请实施例提供的一种定位方法的流程示意图，如图5所示，该方法包括：

503、UE A接收第一指示信息。
对于第一指示信息，本申请实施例提供了以下实现方式：
实现方式一、
在一种可能的实现方式中，该第一指示信息用于指示第一时间差和第二时间差。
示例性的，该第一时间差为第四参考信号的发送时刻(如时刻T B_Tx)与第一参考信号的第一接收时刻(如时刻T B1_1)的时间差，即第一时间差可以为T B_Tx-T B1_1。第二时间差为第四参考信号的发送时刻与第一参考信号的第二接收时刻(时刻T B2_1)的时间差，即第二时间差可以为T B_Tx-T B2_1。
示例性的，第一接收时刻与第四参考信号关联可以理解为：第四参考信号是由UE B的第一天线端口(如panel 1)发送的，第一接收时刻是为该第一天线端口接收第一参考信号的时刻。也就是说，通过将第一接收时刻与第四参考信号关联，可使得UE A明确获知第一时间差是与第四参考信号关联的，从而在UE A接收到第四参考信号之后，便可以根据该UE A接收第四参考信号的接收时刻、第一时间差以及第一参考信号的发送时刻对UE B进行定位。示例性的，第二接收时刻与第五参考信号关联可以理解为：第五参考信号是UE B的第二天线端口(如panel 2)发送的，第二接收时刻是为该第二天线端口接收第一参考信号的时刻。
可选的，第一指示信息还用于指示第一时间差与第四参考信号的标识关联，和/或，第二时间差与第五参考信号的标识关联。也就是说，第一指示信息不仅用于指示第一时间差，还用于指示该第一时间差与第四参考信号的标识关联。以及该第一指示信息不仅用于指示第二时间差，还用于指示该第二时间差与第五参考信号的标识关联。通过指示上述信息，可使得UE A明确获知第一时间差对应第四参考信号的接收时刻，以及第二时间差对应第五参考信号的接收时刻，从而改善了UE B由于反馈给UE A的时间差信息存在模糊，而导致UE A无法正确区分UE B反馈的时间信息来自于UE B的哪个panel的问题。进而，UE A明确区分出了各个时间差信息，提高了UE A区分时间差的效率以及准确率。
实现方式二、
在另一种可能的实现方式中，该第一指示信息还用于指示第三时间差和第四时间差。
可选的，在第一参考信号包括第三端口和第四端口的情况下，上述第一接收时刻和上述第二接收时刻可以为第三端口的第一参考信号的接收时刻。该情况下，第三时间差为第四参考信号的发送时刻与第三接收时刻(如T B1_2)的时间差，即第三时间差可以为T B_Tx-T B1_2。第四时间差为第四参考信号的发送时刻与第四接收时刻(如T B2_2)的时间差，即第四时间差可以为T B_Tx-T B2_2。
可选的，第一指示信息还用于指示第三时间差与第四参考信号的标识关联，和/或，第四时间差与第五参考信号的标识关联。可选的，第一指示信息还用于指示第一时间差与第三端口的标识关联，和/或，第二时间差与第三端口的标识关联。可选的，第一指示信息还用于指示第三时间差与第四端口的标识关联，和/或，第四时间差与第四端口的标识关联。

UE A在获得上述第一指示信息之后，可以根据该第一指示信息获得第一时间差、第二时间差、第三时间差与第四时间差分别是与哪个参考信号关联的。从而可以获知接收第三端口的第一参考信号的天线端口，也用于发送第四参考信号的第四参考信号，即UE A可以获得第三端口的第一参考信号与第四参考信号的第四参考信号是通过同一个panel传输的。进而，UE A可以明确区分各个时间差，提高了区分的效率以及准确度。
可选的，在第一参考信号为单端口的参考信号的情况下，UE A还可以向UETB发送第三参考信号。该情况下，第三时间差为第四参考信号的发送时刻与第三参考信号的第三接收时刻的时间差，即第三时间差可以为T B_Tx-T B1_2。第四时间差为第四参考信号的发送时刻与第三参考信号的第四接收时刻的时间差，即第四时间差可以为T B_Tx-T B2_2。
可理解，关于第一指示信息指示的内容或格式可以参考图2，如表1至表6的描述，这里不再一一赘述。可理解，关于第一时间差、第二时间差、第三时间差以及第四时间差的具体说明，可以参考图2，这里不再详述。
504、UE A根据第一指示信息确定UE B的位置信息。
由于第一时间差关联第四参考信号的标识，第二时间差关联第五参考信号的标识。因此，UE A在获得第一指示信息之后，可以明确区分出第一时间差与第四参考信号的接收时刻可以确定出UE B的一个panel的位置信息，如该UE B的一个panel可以为panel 1。同时，UE A 还可以明确区分出第二时间差与第五参考信号的接收时刻可以确定出UE B的另一个panel的位置信息，如该UE B的另一个panel可以为panel 2。可理解，当UE B包括更多panel时，该UE A还能够对UE B的其他panel进行区分，这里不再一一详述。

可选的，UE A可以接收第四参考信号和第五参考信号。可选的，UE A也可以接收包括第一端口和第二端口的第二参考信号。由于UE B发送一个参考信号，UE A就可以确定出UE B的位置信息。因此，下文将以第四参考信号为例说明本申请实施例提供的方法。应理解，对于UE B发送第四参考信号和第五参考信号，或者发送包括第一端口和第二端口的第二参考信号的方法，可以参考本申请实施例提供的UE B发送第四参考信号的方法。

示例性的，第一接收时刻与第三端口关联，包括：该第一接收时刻为第三端口的第一参考信号的接收时刻。示例性的，第三接收时刻与第四端口关联，包括：该第三接收时刻为所述第四端口的第一参考信号的接收时刻。
可选的，第一指示信息还用于指示与第一时间差关联的第三端口的标识，和/或，与第三时间差关联的第四端口的标识。示例性的，由于第一时间差是第四参考信号的发送时刻与第一接收时刻的时间差，因此，第一时间差关联第三端口的标识，可以表示该第一接收时刻为第三端口的第一参考信号的接收时刻。由于第三时间差是第四参考信号的发送时刻与第三接收时刻的时间差，因此第三时间差关联第四端口的标识，可以表示该第三接收时刻为第四端口的第一参考信号的接收时刻。
可选的，第一指示信息还用于指示与第一时间差关联的第四参考信号的标识。例如，第一指示信息用于指示第一时间差、与第一时间差关联的第三端口的标识，以及与第一时间差关联的第四参考信号的标识。由于第一时间差是通过第四参考信号的发送时刻得到，所以第一指示信息还可以指示与第一时间差关联的第四参考信号的标识。可选的，当UE B发送的参考信号还包括第五参考信号时，该第一指示信息还可以指示与第一时间差关联的第五参考信号的标识。可理解，关于第二时间差的具体说明，可以参考关于第一时间差的描述，这里不再详述。
