Detailed ways

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to 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. Rather, they are merely examples of apparatuses and methods consistent with aspects of the disclosed embodiments as recited in the appended claims.

Terms used in the embodiments of the present disclosure are for the purpose of describing specific embodiments only, and are not intended to limit the embodiments of the present disclosure. As used in the examples of this disclosure and the appended claims, the singular forms "a" and "the" are also intended to include the plural unless the context clearly dictates otherwise. It should also be understood that the term "and/or" as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

It should be understood that although the embodiments of the present disclosure may use the terms first, second, third, etc. to describe various information, the information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of the embodiments of the present disclosure, first information may also be called second information, and similarly, second information may also be called first information. Depending on the context, the words "if" and "if" as used herein may be interpreted as "at" or "when" or "in response to a determination."

The network elements or network functions involved in the embodiments of the present disclosure may be implemented by independent hardware devices, or may be implemented by software in the hardware devices, which is not limited in the embodiments of the present disclosure.

The positioning based on the Sidelink link between the terminal equipment (User Equipment, UE) and the 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.

Fig. 1 shows an exemplary schematic diagram of a method for determining a positioning assistance terminal device provided by an embodiment of the present disclosure. As shown in Figure 1, taking the positioning method based on the downlink time difference of arrival (DL-TDOA) as an example, multiple Road Side Units (RSU) can be installed on the roadside, and each roadside A unit may correspond to fixed location information, for example. The UE measures the positioning signals sent by multiple roadside units through the sidelink link, and based on the positioning signals, the specific location of the UE relative to the RSU can be determined. The multiple RSUs may be greater than or equal to three, for example. For example, the location information of the roadside unit may be included in the positioning signal. For example, the UE may measure the time difference of arrival of the three positioning signals sent by the three roadside units, based on the time difference of arrival of the three positioning signals and the position of each roadside unit information, the UE can determine the location information of the UE, or the location information of the UE relative to a certain roadside unit.

Among them, in addition to DL-TDOA, the positioning scheme also includes uplink time difference of arrival (Uplink time difference of arrival, UL-TDOA), multiple round trip cycles (Multiple round trip time, Multiple RTT), angle of arrival (angle-of-arrival, AOA) Or departure angle (angle-of-departure, AOD), carrier phase positioning and so on. If the positioning result is not converted into absolute position coordinates based on RSU-based GPS and other absolute position information, then the positioning result is relative positioning. On the contrary, it is absolute positioning. The RSU participating in relative positioning or absolute positioning is a positioning assistance UE.

Wherein, in one embodiment of the present disclosure, if only two UEs are involved in the positioning, the two are each other's positioning assistance UEs.

And, in an embodiment of the present disclosure, there are different types of positioning assistance UEs, for example, RSU type positioning assistance UEs may be included. Among them, the RSU-type positioning assistance UE belongs to an infrastructure, and it can provide positioning services by cooperating with other RSUs. For example, a common UE can also be used as a positioning assistance UE, and it is difficult for it to cooperate with other UEs to assist in providing a positioning service. In addition, some positioning assistance UEs have location information such as GPS, which can assist other UEs to perform absolute positioning, and some other positioning assistance UEs may not have location information such as GPS.
