Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with embodiments of the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the embodiments of the disclosure, as detailed in the claims that follow.
The terminology used in the embodiments of the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the embodiments of the present disclosure. As used in the disclosed embodiments and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information in the embodiments of the present disclosure, such information should not be limited by these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of embodiments of the present disclosure. The words "if" and "if," as used herein, may be interpreted as "at" \8230; \8230when "or" when 8230; \823030, when "or" in response to a determination, "depending on the context.
The network element or the network function related in the embodiment of the present disclosure may be implemented by an independent hardware device, or may be implemented by software in a hardware device, which is not limited in the embodiment of the present disclosure.
Positioning based on a Sidelink link between a terminal Equipment (UE) and the UE includes absolute positioning, relative positioning, and ranging. Absolute positioning is also to determine the absolute coordinates of the UE, relative positioning is to determine the coordinates of the UE with respect to a reference point, and ranging is to determine the distance and/or angle of the UE with respect to a reference point. Ranging typically refers to ranging between only two UEs, but absolute positioning and relative positioning may involve multiple assisting UEs to participate in positioning.
Fig. 1 illustrates an example schematic diagram of a method for determining a location assistance terminal device according to an embodiment of the present disclosure. As shown in fig. 1, taking the Downlink time difference of arrival (DL-TDOA) based positioning method as an example, a plurality of Road Side Units (RSUs) may be disposed at the Road Side, and each RSU may correspond to fixed location information, for example. The UE may determine a specific location of the UE relative to the RSU based on positioning signals transmitted by multiple roadside units over the sidelink link by measuring the positioning signals. The plurality of RSUs may be, for example, three or more. For example, the positioning signal may include position information of a road side unit, and the UE may measure time difference of arrival of three positioning signals transmitted by three road side units, for example, and based on the time difference of arrival of the three positioning signals and the position information of each road side unit, the UE may determine the position information of the UE, or the position information of the UE relative to a certain road side unit.
Among them, in addition to DL-TDOA, the positioning scheme has 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, and so on. If the positioning result is that absolute position information such as GPS based on RSU is not converted into absolute position coordinates, the positioning result is relative positioning. And conversely, absolute positioning is carried out. RSUs participating in relative positioning or absolute positioning are positioning assistance UEs.
Among them, in one embodiment of the present disclosure, if positioning involves only two UEs, the two UEs are mutually the positioning assistance UEs of each other.
And, in one embodiment of the present disclosure, there are different types in the positioning assistance UE, such as positioning assistance UE that may include RSU type. Among them, a positioning assistance UE of RSU type belongs to an infrastructure, which can provide a positioning service by cooperating with other RSUs. For example, a normal UE may also be used as a positioning assistance UE, which is difficult to assist in providing positioning services with other UEs. In addition, some positioning assistance UEs have location information such as GPS, which may assist other UEs in absolute positioning, and some other positioning assistance UEs may not have location information such as GPS.
A method, an apparatus, a device, and a storage medium for determining a positioning assistance terminal device according to embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
Fig. 2 is a flowchart illustrating a method for determining a location-assisted terminal device according to an embodiment of the present disclosure, where the method is executed by a first terminal device, and as shown in fig. 2, the method may include the following steps:
step 201, sending SL positioning related request information to a communication device, where the SL positioning related request information is used to request positioning of an auxiliary terminal device;
step 202, determining the positioning auxiliary terminal device based on the response information sent by the communication device for the SL positioning related request information.
