这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开实施例相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开实施例的一些方面相一致的装置和方法的例子。Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the embodiments of the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the embodiments of the present disclosure as detailed in the appended claims.
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。The terms used in the disclosed embodiments are only for the purpose of describing specific embodiments and are not intended to limit the disclosed embodiments.

基于终端设备(User Equipment，UE)和UE间Sidelink链路的定位包括绝对定位、相对定位以及测距。绝对定位也即确定UE的绝对坐标，相对定位则是确定UE相对一个参考点的坐标，测距则是确定UE相对一个参考点的距离和/或角度。测距通常是指仅两个UE间进行测距，但绝对定位和相对定位则可能涉及多个辅助UE来参与定位。Positioning based on the sidelink link between the terminal equipment (User Equipment, UE) and UE includes absolute positioning, relative positioning and ranging. Absolute positioning is to determine the absolute coordinates of the UE, relative positioning is to determine the coordinates of the UE relative to a reference point, and ranging is to determine the distance and/or angle of the UE relative to a reference point. Ranging usually refers to ranging between only two UEs, but absolute positioning and relative positioning may involve multiple auxiliary UEs to participate in positioning.
图1示出为本公开实施例所提供的一种定位辅助终端设备的重新选择方法的举例示意图。如图1所示，以基于下行到达时差(Downlink time difference of arrival，DL-TDOA)的定位方法为例，多个路侧单元(Road Side Unit，RSU)可以设置于路侧，每个路侧单元例如可以对应固定位置信息。UE通过测量多个路侧单元通过sidelink链路发送的定位信号，基于该定位信号可以确定UE相对于RSU的具***置。多个RSU例如可以大于等于三。例如，定位信号中可以包括路侧单元的位置信息，该UE例如可以测量三个路侧单元发送的三个定位信号的到达时间差，基于该三个定位信号的到达时间差和各路侧单元的位置信息，UE可以确定UE的位置信息，或者UE相对于某一个路侧单元的位置信息。FIG1 shows an example schematic diagram of a reselection method for a positioning auxiliary terminal device provided by an embodiment of the present disclosure. As shown in FIG1 , taking a positioning method based on a downlink time difference of arrival (DL-TDOA) as an example, multiple road side units (RSU) can be set on the road side, and each road side unit can correspond to fixed position information, for example. The UE measures the positioning signals sent by multiple road side units through the sidelink link, and based on the positioning signals, the UE can determine the specific position of the UE relative to the RSU. The number of multiple RSUs can be greater than or equal to three, for example. For example, the positioning signal can include the position information of the road side unit, and the UE can measure the arrival time difference of three positioning signals sent by three road side units, and based on the arrival time difference of the three positioning signals and the position information of each road side unit, the UE can determine the position information of the UE, or the position information of the UE relative to a certain road side unit.
其中，除了DL-TDOA，定位方案还有上行到达时差(Uplink time difference of arrival，UL-TDOA)，多个往返周期(Multiple round trip time，Multiple RTT)，到达角度(angle-of-arrival，AOA)或者离开角度(angle-of-departure，AOD)，载波相位定位等等。如果定位结果是没有基于RSU的GPS等绝对位置信息转换成绝对位置坐标，那么定位结果就是相对定位。反之，就是绝对定位。参与到相对定位或者绝对定位的RSU就是定位辅助UE。Among them, in addition to DL-TDOA, positioning solutions also include uplink time difference of arrival (UL-TDOA), multiple round trip time (Multiple RTT), angle of arrival (AOA) or angle of departure (AOD), carrier phase positioning, etc. If the positioning result is not converted into absolute position coordinates based on absolute position information such as GPS based on RSU, then the positioning result is relative positioning. Otherwise, it is absolute positioning. The RSU participating in relative positioning or absolute positioning is a positioning-assisted UE.
其中，在本公开的一个实施例之中，如果定位仅涉及到两个UE，则二者互相是对方的定位辅助UE。In one embodiment of the present disclosure, if positioning involves only two UEs, the two UEs are each other's positioning-assisted UEs.
以及，在本公开的一个实施例之中，定位辅助UE中存在不同的类型，比如可以包括RSU类型的定位辅助UE。其中，RSU类型的定位辅助UE属于一种基础设施，它可以通过与其它RSU一起协作提供定位服务。比如普通的UE也可以作为定位辅助UE，其就难以与其它UE一起协助提供定位服务。另外，有些定位辅助UE有GPS等位置信息，其可以辅助其它UE进行绝对定位，还有，其它一些定位辅助UE可能不具备GPS等位置信息。And, in one embodiment of the present disclosure, there are different types of positioning assistance UEs, such as RSU type positioning assistance UEs. Among them, RSU type positioning assistance UEs belong to a kind of infrastructure, which can provide positioning services by collaborating with other RSUs. For example, ordinary UEs can also be used as positioning assistance UEs, but it is difficult for them to assist in providing positioning services with other UEs. In addition, some positioning assistance UEs have location information such as GPS, which can assist other UEs in absolute positioning. In addition, some other positioning assistance UEs may not have location information such as GPS.
