detailed description

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, but not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

FIG. 1 is a schematic flowchart of a method for determining a location according to an embodiment of the present disclosure. The location determination method shown in this embodiment can be applied to terminals, which include but are not limited to electronic devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. in the serving cell in the network.

As shown in FIG. 1 , the method for determining the position may include the following steps:

In step S11, the location of the terminal is determined according to at least one reference signal related to a ground reference site.

Wherein, determining the position of the terminal according to at least one reference signal related to a terrestrial reference site may be when a request for reporting a position sent by a serving cell in a non-terrestrial network is received, or when the terminal needs to obtain its own position, and This is performed when the terminal does not have the ability to locate via a satellite navigation system.

Determining the position of the terminal according to at least one reference signal related to the ground reference station may specifically be receiving a first reference signal sent by the ground reference station, and then determining the relative position or absolute position of the terminal according to the first reference signal. That is, the first reference signal from the ground reference station can be received, and then the terminal can determine its own position.

Alternatively, a second reference signal may be sent to at least one terrestrial reference station, wherein the second reference signal is used for the at least one terrestrial reference station to determine the position of the terminal. That is, by sending the second reference signal to the ground reference station, the ground reference station determines the position of the terminal.

In one embodiment, when a serving cell in a non-terrestrial network can send a request for location reporting to the terminal, or when the terminal needs to obtain its own location, the terminal can determine whether it has the capability of positioning itself through a satellite navigation system.

If the terminal has the capability of positioning through the satellite navigation system, it can determine its own position without the aid of external equipment. If the terminal does not have the ability to locate through the satellite navigation system, it can determine the position by communicating with the ground reference station. For example, a first reference signal sent by a ground reference station can be received, and then the terminal can determine the position of the terminal according to the first reference signal, or a second reference signal can be sent to the ground reference station, and then the ground reference station can determine the position of the terminal.

It should be noted that the terrestrial reference site is not a terrestrial base station, and is only used to determine the location of the terminal according to the second reference signal sent by the terminal, or to send the first reference signal to the terminal, which can exchange the reference signal with the terminal without the terminal accessing. Specifically, the first reference signal may be sent to the terminal in a broadcast manner, or the second reference signal sent by the terminal may be received according to the second configuration information, for example, in a preset time-frequency resource. Except for sending the first reference signal to the terminal and receiving the second reference signal sent by the terminal, the terrestrial reference station may not have the ability to perform other communication with the terminal.

In one embodiment, when the terminal needs to obtain its own location, the serving cell in the non-terrestrial network can send the information of a geographical area to the terminal, and after the terminal determines its own location, the terminal can determine its own location according to the relationship between its own location and the geographical area. Determine what needs to be done.

For example, if your own location is not within the geographic area, you may not measure neighboring cells, but if your own location is within the geographic area, you can measure neighboring cells, and then report the measurement results to the network or perform cell reselection based on the measurement results. .

In one embodiment, the terminal may broadcast the second reference signal to the ground reference station only after receiving the first reference signal broadcast by the ground reference station. Accordingly, when the terminal receives the first reference signal, it may determine that there is a nearby The ground reference station then broadcasts the second reference signal, and before receiving the first reference signal, there is no need to broadcast the second reference signal, which is beneficial to reduce the power consumption of the terminal. Therefore, the ground reference station determines the position of the terminal according to the first reference signal sent by the ground reference station and the second reference signal sent by the terminal after receiving the second reference signal.

FIG. 2 is a schematic flowchart of another method for determining a location according to an embodiment of the present disclosure. As shown in FIG. 2 , the determining the position of the terminal according to at least one reference signal related to the ground reference site includes:

In step S111, a first reference signal sent by a ground reference station is received, and a relative position or an absolute position of the terminal is determined according to the first reference signal.

In one embodiment, the ground reference station may send a first reference signal to the terminal, and then the terminal determines its own relative position or absolute position according to the first reference signal.

FIG. 3 is a schematic flowchart of yet another method for determining a location according to an embodiment of the present disclosure. As shown in FIG. 3 , the determining the absolute position of the terminal according to the first reference signal includes:

In step S1111, the relative position of the terminal is determined according to the first reference signal, and/or the absolute position of the terminal is determined according to the first reference signal and the position of the ground reference site.

In one embodiment, the terminal may determine the relative position of the terminal according to the first reference signal when the position of the ground reference site is not determined. For example, the distance from the terminal to the ground reference site may be determined according to the reception time of the first reference signal and the transmission time of the first reference signal, wherein the transmission time may be sent to the terminal by the ground reference site together with the first reference signal, and the terminal Based on the reception time and the transmission time, the transmission duration of the first reference signal can be calculated, and then the distance from the terminal to the ground reference site can be calculated according to the transmission speed (eg, the speed of light) and transmission duration of the first reference signal.

Further, the relative position of the terminal relative to the ground reference site can be determined according to the receiving angle at which the terminal receives the first reference signal and the above-mentioned distance, for example, the coordinates of the terminal in a rectangular coordinate system with the ground reference site as the center.

When the terminal determines the position of the ground reference station (for example, the position in the world coordinate system), the ground reference station can send the position of the ground reference station to the terminal by broadcasting, and then the terminal can further determine its own absolute position. The process may be to first determine the above-mentioned relative position, and then determine the absolute position of the terminal based on the position and relative position of the ground reference site, wherein the absolute position may refer to the position in the world coordinate system, or may be in the non-terrestrial network. The position in the coordinate system of the serving cell.

FIG. 4 is a schematic flowchart of yet another method for determining a location according to an embodiment of the present disclosure. As shown in FIG. 4 , the determining the absolute position of the terminal according to the first reference signal includes:

In step S1113, the absolute position of the terminal is determined according to the position of each of the first reference signals and each of the ground reference sites.

In one embodiment, the terminal may receive first reference signals respectively sent by multiple ground reference sites, and receive the position of each ground reference site, and then determine the terminal according to each first reference signal and the position of each ground reference site absolute position.

For example, the terminal can complete positioning according to the difference between the reception times of the first reference signals sent by multiple ground reference sites and finally obtain the absolute position. Only calculating the absolute position according to the first reference signal and the position sent by one ground reference station is beneficial to reduce errors and improve the accuracy and precision of the position.

Fig. 5 is a schematic flowchart of yet another method for determining a location according to an embodiment of the present disclosure. As shown in Figure 5, the method further includes:

In step S12, the absolute position is sent to the serving cell in the non-terrestrial network, or the relative position and the identifier of the terrestrial reference site are sent to the serving cell in the non-terrestrial network.

In one embodiment, after determining its own location, the terminal may send the location to the serving cell in the non-terrestrial network. For example, if the determined position is an absolute position, the absolute position may be sent to the serving cell in the non-terrestrial network. For example, if the determined position is a relative position, the relative position and the identity of the terrestrial reference site may be sent to the serving cell in the non-terrestrial network. The serving cell in the non-terrestrial network can determine the location of the terrestrial reference site according to the identity of the terrestrial reference site, and then determine the absolute location of the terminal according to the location of the reference site and the relative location of the terminal.

FIG. 6 is a schematic flowchart of yet another method for determining a location according to an embodiment of the present disclosure. As shown in FIG. 6 , the receiving the first reference signal sent by the ground reference station includes:

In step S1114, obtain first configuration information broadcast by a terrestrial reference site, or sent by a serving cell in a non-terrestrial network, or pre-stored;

In step S1115, determining the resource for the ground reference station to send the first reference signal according to the first configuration information;

In step S1116, the first reference signal is received at the resource.

In one embodiment, since the terminal receives the first reference signal and does not need to access the terrestrial reference site, it still needs to determine how to receive the first reference signal, and the first configuration information used to indicate how to receive the first reference signal may be It is broadcast by the terrestrial reference station, or can be sent to the terminal by the serving cell in the non-terrestrial network, or stored in advance by the terminal, so that the terminal can determine the resources of the terrestrial reference station to send the first reference signal according to the first configuration information, such as frequency domain resources and time domain resources, information such as the period for receiving the first reference signal can also be determined, and then the first reference signal is received at the determined resource, and the transmission moment of the first reference signal can be determined.

FIG. 7 is a schematic flowchart of yet another method for determining a location according to an embodiment of the present disclosure. As shown in FIG. 7 , the determining the location of the terminal according to at least one reference signal related to the ground reference site includes:

In step S112, a second reference signal is sent to at least one ground reference station, wherein the second reference signal is used for the at least one ground reference station to determine the position of the terminal.

In one embodiment, the terminal may send a second reference signal to a ground reference station, and then the ground reference station determines its relative position or absolute position according to the second reference signal.

FIG. 8 is a schematic flowchart of yet another method for determining a location according to an embodiment of the present disclosure. As shown in FIG. 8 , the sending the second reference signal to at least one ground reference station includes:

In step S1121, a second reference signal is sent to a ground reference station according to the second configuration information, wherein the ground reference station stores the second configuration information in advance.

In one embodiment, since the terminal transmits the second reference signal to the ground reference station, it does not need to access the ground reference station, but the ground reference station needs to know how to receive the second reference signal, and the terrestrial reference station is used to indicate how to receive the second reference signal. The second configuration information can be pre-stored by the ground reference station, so that the terminal can send the second reference signal to the ground reference station according to the second configuration information, for example, send the second reference signal in a specific frequency band, and the ground reference station knows the The second configuration information, so that the ground reference station can also receive the second reference signal in the specific frequency band.

The identification information of the terminal may be included in the second reference signal sent by the terminal, so that after the ground reference station subsequently sends the determined terminal location and identification information to the serving cell in the non-terrestrial network, the serving cell in the non-terrestrial network can use the identification The information determines which terminal the received location is for.

FIG. 9 is a schematic flowchart of yet another method for determining a location according to an embodiment of the present disclosure. As shown in FIG. 9 , the sending the second reference signal to at least one ground reference station includes:

In step S1122, the second reference signal is broadcast to a plurality of terrestrial reference sites.

In one embodiment, the terminal may broadcast the second reference signal to a plurality of terrestrial reference stations, so that each terrestrial reference station may determine the position of the terminal, and then the terrestrial reference station may send the determined position of the terminal to the non-terrestrial network Serving cell, so that the serving cell in the non-terrestrial network can calculate the mean value (also weighted summation) based on the received multiple positions as the position of the terminal.

Optionally, the terrestrial reference site is located at the edge of a serving cell in the non-terrestrial network.

In one embodiment, when the terminal is located at the edge of a cell, it can perform operations such as switching cells (eg, cell switching/reselection).

In a conventional land network, the terminal does not need to report the location of the terminal to the base station when switching cells, because the terminal can independently detect the signal strength of the neighboring cells, and then report the detection result to the base station of the current serving cell, and then determine whether to switch cells.

In the non-terrestrial network, since the terminal needs to communicate with the satellite, the coverage radius of the satellite signal can be very large, so that the radius of the cell in the non-terrestrial network is very large, so when it is located in the center of the cell, it is difficult to receive the signal sent by the base station in the adjacent cell. If the terminal is also configured to measure the adjacent cell at this time, it will increase the unnecessary power consumption of the terminal. If the non-terrestrial network serving cell has the location information of the terminal, so that the terminal can be configured to measure the adjacent cell or switch to the adjacent cell according to the location information of the terminal, not only the energy consumption of the terminal can be saved, but also the cell handover or Cell reselection. Therefore, the terminal needs to report its own location to the serving cell in the non-terrestrial network for analysis and processing, such as cell reselection and cell handover using the terminal.

That is to say, when the terminal is located at the edge of the serving cell in the non-terrestrial network, it is more likely to report its own position, then the terrestrial reference site can be set at the edge of the serving cell in the non-terrestrial network to interact with the terminal that needs to report the location. reference signal.

Optionally, the method is in response to receiving a request for reporting a location sent by a serving cell in a non-terrestrial network, or the terminal needs to acquire its own location. That is, the method described in any one of the above-mentioned embodiments may be performed when the terminal receives a request for reporting the location sent by the serving cell in the non-terrestrial network, or when the terminal needs to obtain its own location, but the terminal does not have the Performed without the ability to locate via a satellite navigation system.

In one embodiment, a ground reference site may be used to determine the location of the terminal.

Determining the position of the terminal according to at least one reference signal associated with the terminal may specifically be receiving a first reference signal sent by a ground reference station, and then determining the relative position or absolute position of the terminal according to the first reference signal. That is, the first reference signal from the ground reference station can be received, and then the terminal can determine its own position.

Wherein, when the terminal receives the first reference signal and sends the second reference signal to the terrestrial reference site, it receives a request for reporting the location sent by the serving cell in the non-terrestrial network, or when the terminal needs to obtain its own location, and the It is executed when the terminal does not have the ability to locate through the satellite navigation system.

The station determines the location of the terminal. In this process, there is no need to communicate with equipment such as base stations and core networks in non-terrestrial networks, which is conducive to quickly determining the location of the terminal to ensure the validity of the determined location.

In one embodiment, when the ground reference station does not determine its own position, it may determine the relative position of the terminal according to the second reference signal. For example, the distance between the terminal and the ground reference site can be determined according to the receiving time of the second reference signal and the sending time of the second reference signal, wherein the sending time can be sent by the terminal to the ground reference site together with the second reference signal, and the ground The reference site can calculate the transmission duration of the second reference signal based on the reception time and the transmission time, and then calculate the distance from the terminal to the ground reference site according to the transmission speed (such as the speed of light) and transmission duration of the second reference signal. The second reference signal sent by the terminal may include identification information of the terminal, and the ground reference station may also acquire the identification of the terminal from the second reference signal.

Further, the relative position of the terminal relative to the ground reference station can be determined according to the receiving angle at which the ground reference station receives the second reference signal and the above-mentioned distance, for example, the coordinates of the terminal in a rectangular coordinate system with the ground reference station as the center.

When the ground reference station determines its own position (eg, the position in the world coordinate system), the ground reference station may determine the absolute position of the terminal based on its own position and the relative position of the terminal.

In step S22, the absolute position is sent to the serving cell in the non-terrestrial network, or the relative position and the identifier of the terrestrial reference site are sent to the serving cell in the non-terrestrial network.

Among them, the ground reference site can send information such as absolute position, relative position, identification of the ground reference site, UE identification and other information to the A serving cell in a non-terrestrial network. Specifically, when the NTN network is in the transparent transmission mode, the ground reference station can send the above information to the NTN serving cell of the UE through a wired link such as an Xn interface, and when the NTN network is in the regeneration mode, the ground reference station can use the wireless link. For example, the Uu interface sends the above information to the NTN serving cell of the UE.
