[0001] The present disclosure relates to the field of communication technology, and in particular, to a position determination method, a position determination device, an electronic device, and a computer-readable storage medium. Background Art

[0002] With the development of communication technology, non-terrestrial networks (NTN) have been introduced in 5G and 6G communication technologies. In non-terrestrial networks, communication signals between base stations and terminals can be forwarded or processed through medium / low-orbit satellites, and the coverage radius of the cell can reach 100 kilometers or even 1,000 kilometers.

[0003] The coverage area of ​​a cell in a non-terrestrial network is very large. Within its coverage area, there are various types of terminals serving as user equipment, some of which have the capability to locate through the Global Navigation Satellite System (GNSS), while others do not.

[0004] For those terminals that do not have the positioning capability through the satellite navigation system, the cells of the non-terrestrial network need to obtain their positions in certain cases, such as in the case of cell switching, cell reselection, etc.

[0005] In the related technology, although positioning solutions have been proposed for terminals that do not have the ability to locate through satellite navigation systems, such as RAT-dependent positioning technology of R16, the positioning process involves equipment such as the core network of non-terrestrial networks. In non-terrestrial networks, communication signals need to be transmitted via satellites. It takes a long time to transmit the information in the positioning process to the core network, making it difficult to quickly determine the location of the terminal. Summary of the invention

[0037] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0038] Figure 1 The present invention is a schematic flow chart of a method for determining a position according to an embodiment of the present invention. The method for determining a position shown in this embodiment can be applied to a terminal, including but not limited to electronic devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The terminal can be a user device and can be in a service cell in a non-terrestrial network.

[0039] like Figure 1 As shown, the location determination method may include the following steps:

[0040] In step S11, the location of the terminal is determined based on at least one reference signal associated with a ground reference site.

[0041] Among them, determining the position of the terminal based on at least one reference signal related to a ground reference site can be performed when a request for reporting the position is received from a service cell in a non-terrestrial network, or when the terminal needs to obtain its own position and the terminal does not have the ability to locate through a satellite navigation system.

[0042] Determining the position of the terminal according to at least one reference signal related to a ground reference site may specifically include receiving a first reference signal sent by the ground reference site, 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 site may be received, and then the terminal determines its own position.

[0043] Alternatively, a second reference signal may be sent to at least one ground reference site, wherein the second reference signal is used by the at least one ground reference site to determine the location of the terminal. That is, by sending the second reference signal to the ground reference site, the ground reference site determines the location of the terminal.

[0044] In one embodiment, when a serving cell in a non-terrestrial network may send a request to the terminal to report its position, or when the terminal needs to obtain its own position, the terminal may determine whether it has the capability of positioning itself through a satellite navigation system.

[0045] If the terminal has the ability to locate through a satellite navigation system, then it can determine its own position without the help of external equipment. If the terminal does not have the ability to locate through a satellite navigation system, then it can determine its position by communicating with a ground reference site. For example, a first reference signal sent by a ground reference site can be received, and then the terminal determines the position of the terminal based on the first reference signal, or a second reference signal can be sent to a ground reference site, and then the ground reference site determines the position of the terminal.

[0046] It should be noted that the ground reference site is not a ground base station, and is only used to determine the terminal location based on the second reference signal sent by the terminal, or to send the first reference signal to the terminal, and it can exchange reference signals with the terminal without the terminal access. Specifically, the first reference signal can be sent to the terminal by broadcasting, or the second reference signal sent by the terminal can be received according to the second configuration information, such as in a preset time-frequency resource. In addition to sending the first reference signal to the terminal and receiving the second reference signal sent by the terminal, the ground reference site may not have the ability to communicate with the terminal in other ways.

[0047] According to the embodiments of the present disclosure, when the terminal does not have the ability to locate itself through a satellite navigation system, it can determine its own position based on a first reference signal sent by a ground reference site, or it can send a second reference signal to the ground reference site and allow the ground reference site to determine the terminal's position. In this process, there is no need to communicate with base stations, core networks and other equipment in non-terrestrial networks, which is conducive to quickly determining the terminal's position to ensure the validity of the determined position.

[0048] In one embodiment, when the terminal needs to obtain its own location, the service cell in the non-terrestrial network can send information about a geographical area to the terminal. After determining its own location, the terminal can determine the operation to be performed based on the relationship between its own location and the geographical area.

[0049] For example, if the location is not within the geographical area, then the neighboring cells may not be measured. However, if the location is within the geographical area, then the neighboring cells may be measured, and then the measurement results may be reported to the network or cell reselection may be performed based on the measurement results.

[0050] In one embodiment, the terminal may broadcast the second reference signal to the ground reference site only after receiving the first reference signal broadcast by the ground reference site. Accordingly, when the terminal receives the first reference signal, it can determine that there is a ground reference site nearby, and then broadcast the second reference signal. Before receiving the first reference signal, there is no need to broadcast the second reference signal, which is conducive to reducing the power consumption of the terminal. Thus, the ground reference site determines the location of the terminal based on the first reference signal it sends and the second reference signal received from the terminal.

[0051] Figure 2 FIG. 1 is a schematic flow chart of another method for determining a position according to an embodiment of the present disclosure. Figure 2 As shown, determining the position of the terminal according to at least one reference signal associated with a ground reference site includes:

[0052] In step S111, a first reference signal sent by a ground reference site is received, and a relative position or an absolute position of the terminal is determined according to the first reference signal.

[0053] In one embodiment, the ground reference site may send a first reference signal to the terminal, and the terminal determines its own relative position or absolute position according to the first reference signal.

[0054] Figure 3 FIG. 1 is a schematic flow chart of another method for determining a position according to an embodiment of the present disclosure. Figure 3 As shown, determining the absolute position of the terminal according to the first reference signal includes:

[0055] 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.

[0056] In one embodiment, when the terminal does not determine the position of the ground reference station, the terminal can determine the relative position of the terminal according to the first reference signal. For example, the distance from the terminal to the ground reference station can 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 can be sent to the terminal by the ground reference station together with the first reference signal, and the terminal can calculate the transmission time of the first reference signal based on the reception time and the transmission time, and then calculate the distance from the terminal to the ground reference station according to the transmission speed (such as the speed of light) and the transmission time of the first reference signal.

[0057] Furthermore, the relative position of the terminal relative to the ground reference site may be determined based on the reception angle of the first reference signal received by the terminal and the above distance, for example, the coordinates of the terminal in a rectangular coordinate system with the ground reference site as the center.

[0058] When the terminal determines the position of the ground reference site (for example, the position in the world coordinate system), the ground reference site can send the position of the ground reference site to the terminal by broadcasting, and the terminal can further determine its absolute position. The process can 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 can refer to the position in the world coordinate system, or the position in the coordinate system of the service cell in the non-ground network.

[0059] Figure 4 FIG. 1 is a schematic flow chart of another method for determining a position according to an embodiment of the present disclosure. Figure 4 As shown, determining the absolute position of the terminal according to the first reference signal includes:

[0060] In step S1112, first reference signals respectively sent by a plurality of ground reference sites and the position of each of the ground reference sites are received;

[0061] 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.

[0062] In one embodiment, the terminal may receive first reference signals respectively transmitted by a plurality of ground reference sites, and receive the position of each ground reference site, and then determine the absolute position of the terminal according to each first reference signal and the position of each ground reference site.

[0063] For example, the terminal can complete the 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. For example, the positioning can be performed based on the time difference of arrival method (TDOA for short). Compared with calculating the absolute position based on the first reference signal and position sent by only one ground reference site, it is beneficial to reduce errors and improve the accuracy and precision of the position.

[0064] Figure 5 FIG. 1 is a schematic flow chart of another method for determining a position according to an embodiment of the present disclosure. Figure 5 As shown, the method also includes:

[0065] In step S12, the absolute position is sent to a serving cell in a non-terrestrial network, or the relative position and the identifier of the ground reference station are sent to a serving cell in the non-terrestrial network.

[0066] In one embodiment, after determining its own position, the terminal may send the position to a serving cell in a non-terrestrial network. For example, if the determined position is an absolute position, the absolute position may be sent to a serving cell in a non-terrestrial network. For example, if the determined position is a relative position, the relative position and an identifier of a ground reference station may be sent to a serving cell in a non-terrestrial network, so that the serving cell in the non-terrestrial network may determine the position of the ground reference station according to the identifier of the ground reference station, and further determine the absolute position of the terminal according to the position of the reference station and the relative position of the terminal.

[0067] Figure 6 FIG. 1 is a schematic flow chart of another method for determining a position according to an embodiment of the present disclosure. Figure 6 As shown, the receiving a first reference signal sent by a ground reference station includes:

[0068] In step S1114, first configuration information broadcasted by a terrestrial reference site, sent by a serving cell in a non-terrestrial network, or pre-stored is obtained;

[0069] In step S1115, determining, according to the first configuration information, a resource for the ground reference site to send the first reference signal;

[0070] In step S1116, the first reference signal is received on the resource.

[0071] In one embodiment, since the terminal receives the first reference signal and does not need to access the ground 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 can be broadcast by the ground reference site, or can be sent to the terminal by a service cell in a non-terrestrial network, or can be pre-stored by the terminal, so that the terminal can determine the resources used by the ground reference site to send the first reference signal based on the first configuration information, such as frequency domain resources and time domain resources, and can also determine information such as the period for receiving the first reference signal, and then receive the first reference signal in the determined resources, and can determine the sending time of the first reference signal.

[0072] Figure 7 FIG. 1 is a schematic flow chart of another method for determining a position according to an embodiment of the present disclosure. Figure 7 As shown, determining the position of the terminal according to at least one reference signal associated with a ground reference site includes:

[0073] In step S112, a second reference signal is sent to at least one ground reference site, wherein the second reference signal is used by the at least one ground reference site to determine the position of the terminal.

[0074] In one embodiment, the terminal may send a second reference signal to a ground reference site, and the ground reference site determines its own relative position or absolute position according to the second reference signal.

[0075] Figure 8 FIG. 1 is a schematic flow chart of another method for determining a position according to an embodiment of the present disclosure. Figure 8 As shown, sending a second reference signal to at least one ground reference site includes:

[0076] In step S1121, a second reference signal is sent to a ground reference site according to second configuration information, wherein the ground reference site pre-stores the second configuration information.

[0077] In one embodiment, since the terminal sends the second reference signal to the ground reference site and does not need to access the ground reference site, the ground reference site needs to know how to receive the second reference signal, and the second configuration information for indicating how to receive the second reference signal can be pre-stored by the ground reference site, so that the terminal can send the second reference signal to the ground reference site according to the second configuration information, for example, sending the second reference signal in a specific frequency band, and the ground reference site knows the second configuration information, so that the ground reference site can also receive the second reference signal in the specific frequency band.

[0078] Among them, the second reference signal sent by the terminal may include the identification information of the terminal, so that after the ground reference site subsequently sends the determined terminal location and identification information to the service cell in the non-terrestrial network, the service cell in the non-terrestrial network can determine which terminal the received location is for based on the identification information.

[0079] Fig. 9 FIG. 1 is a schematic flow chart of another method for determining a position according to an embodiment of the present disclosure. Fig. 9 As shown, sending a second reference signal to at least one ground reference site includes:

[0080] In step S1122, a second reference signal is broadcast to a plurality of ground reference sites.

[0081] In one embodiment, the terminal may broadcast a second reference signal to multiple ground reference sites so that each ground reference site can determine the position of the terminal respectively. The ground reference site can then send the determined terminal position to a service cell in a non-terrestrial network, so that the service cell in the non-terrestrial network can calculate an average (or a weighted sum) based on the received multiple positions as the terminal's position.

[0082] Optionally, the terrestrial reference site is located at an edge of a serving cell in the non-terrestrial network.

[0083] In one embodiment, when the terminal is located at the cell edge, it may switch cells and perform other operations (eg, cell switching / reselection).

[0084] In conventional terrestrial networks, a terminal does not need to report its own location to a base station when switching cells, because the terminal can autonomously detect the signal strength of neighboring cells and then report the detection results to the base station of the current serving cell to determine whether to switch cells.

[0085] In non-terrestrial networks, since the terminal needs to communicate with the satellite, the coverage radius of the satellite signal can be very large, which makes the radius of the cell in the non-terrestrial network very large. When it is located in the center of the cell, it is difficult to receive the signal sent by the base station in the neighboring cell. If the terminal is also configured to measure the neighboring cell at this time, it will increase the unnecessary power consumption of the terminal. If the non-terrestrial network service cell has the location information of the terminal, and the terminal is configured to measure the neighboring cell or switch to the neighboring cell according to the location information of the terminal, it can not only save the energy consumption of the terminal, but also complete the cell switching or cell reselection in real time. Therefore, the terminal needs to report its own location to the service cell in the non-terrestrial network for analysis and processing, for example, it can use the cell reselection and cell switching of the terminal.

[0086] That is to say, when the terminal is located at the edge of the service cell in the non-terrestrial network, it is more likely to need to report its own location. In this case, the ground reference station can be set at the edge of the service cell in the non-terrestrial network to exchange reference signals with the terminal that needs to report its location.

[0087] 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 obtain its own location. That is, the method in any one of the above embodiments can be executed when the terminal receives a request for reporting a location sent by a serving cell in a non-terrestrial network, or the terminal needs to obtain its own location, and the terminal does not have the ability to locate through a satellite navigation system.

[0088] Fig.10It is a schematic flow chart of a method for determining a position according to an embodiment of the present disclosure. The method for determining a position shown in this embodiment can be applied to a ground reference site, and the ground reference site can exchange reference signals with a terminal without access to the terminal, and the terminal includes but is not limited to electronic devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices, and the terminal can be a user device and can be in a service cell in a non-terrestrial network.

[0089] like Fig.10 As shown, the location determination method may include the following steps:

[0090] In step S21, the location of the terminal is determined according to at least one reference signal associated with the terminal.

[0091] In one embodiment, ground reference sites may be used to determine the location of the terminal.

[0092] Determining the position of the terminal according to at least one reference signal associated with the terminal may specifically include receiving a first reference signal sent by a ground reference site, 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 site may be received, and then the terminal determines its own position.

[0093] Alternatively, a second reference signal may be sent to at least one ground reference site, wherein the second reference signal is used by the at least one ground reference site to determine the location of the terminal. That is, by sending the second reference signal to the ground reference site, the ground reference site determines the location of the terminal.

[0094] The terminal receives the first reference signal and sends the second reference signal to the ground reference site when a request for reporting the position is received from a service cell in a non-terrestrial network, or the terminal needs to obtain its own position, but the terminal does not have the ability to locate itself through a satellite navigation system.

[0095] According to the embodiments of the present disclosure, for terminals that do not have the ability to locate themselves through a satellite navigation system, a first reference signal can be sent to the terminal for the terminal to determine its own position, or a second reference signal sent by the terminal can be received and the position of the terminal can be determined by a ground reference site. In this process, there is no need to communicate with base stations, core networks and other equipment in non-terrestrial networks, which is conducive to quickly determining the position of the terminal to ensure the validity of the determined position.

[0096] Fig.11 FIG. 1 is a schematic flow chart of a method for determining a position according to an embodiment of the present disclosure. Fig.11 As shown, determining the position of the terminal according to at least one reference signal associated with the terminal includes:

[0097] In step S211, a second reference signal sent by a terminal is received, and a position of the terminal is determined according to the second reference signal.

[0098] In one embodiment, the terminal may send a second reference signal to a ground reference site, and the ground reference site determines its own relative position or absolute position according to the second reference signal.

[0099] Fig.12 FIG. 1 is a schematic flow chart of another method for determining a position according to an embodiment of the present disclosure. Fig.12 As shown, determining the position of the terminal according to the second reference signal includes:

[0100] In step S2111, the relative position of the terminal is determined according to the received second reference signal, or the absolute position of the terminal is determined according to the second reference signal and the position of the ground reference site.

[0101] In one embodiment, when the ground reference station has not determined its own position, the relative position of the terminal can be determined based on the second reference signal. For example, the distance from the terminal to the ground reference station can be determined based on 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 station together with the second reference signal, and the ground reference station can calculate the transmission time of the second reference signal based on the receiving time and the sending time, and then calculate the distance from the terminal to the ground reference station based on the transmission speed (such as the speed of light) and the transmission time of the second reference signal. The second reference signal sent by the terminal can include the identification information of the terminal, and the ground reference station can also obtain the identification of the terminal from the second reference signal.

[0102] Furthermore, the relative position of the terminal relative to the ground reference site can be determined based on the reception angle of the second reference signal received by the ground reference site and the above distance, for example, the coordinates of the terminal in a rectangular coordinate system with the ground reference site as the center.

[0103] When the ground reference station determines its own position (eg, the position in the world coordinate system), the ground reference station can determine the absolute position of the terminal based on its own position and the relative position of the terminal.

[0104] Fig.13 FIG. 1 is a schematic flow chart of another method for determining a position according to an embodiment of the present disclosure. Fig.13 As shown, the method also includes:

[0105] In step S22, the absolute position is sent to a serving cell in the non-terrestrial network, or the relative position and the identifier of the ground reference station are sent to a serving cell in the non-terrestrial network.

[0106] Among them, the ground reference site can send the absolute position, relative position, ground reference site identifier, UE identifier and other information to the service cell in the non-terrestrial network through a wireless link or a wired link (specifically, through interfaces such as Uu, Xn, N1, N2, etc.). Specifically, when the NTN network is in transparent transmission mode, the ground reference site can send the above information to the NTN service cell of the UE through a wired link such as the Xn interface. When the NTN network is in regeneration mode, the ground reference site can send the above information to the NTN service cell of the UE through a wireless link such as the Uu interface.

[0107] In one embodiment, after determining the position of the terminal, the ground reference station may send the position to a service cell in the non-terrestrial network. For example, if the determined position is an absolute position, the absolute position may be sent to the service cell in the non-terrestrial network. For example, if the determined position is a relative position, the relative position and the identifier of the ground reference station may be sent to the service cell in the non-terrestrial network, so that the service cell in the non-terrestrial network may determine the position of the ground reference station according to the identifier of the ground reference station, and further determine the absolute position of the terminal according to the position of the reference station and the relative position of the terminal.

[0108] Fig.14 FIG. 1 is a schematic flow chart of another method for determining a position according to an embodiment of the present disclosure. Fig.14 As shown, the second reference signal sent by the receiving terminal includes:

[0109] In step S2112, a second reference signal sent by the terminal is received according to the pre-stored second configuration information.

[0110] In one embodiment, since the terminal sends the second reference signal to the ground reference site and does not need to access the ground reference site, the ground reference site needs to know how to receive the second reference signal, and the second configuration information for indicating how to receive the second reference signal can be pre-stored by the ground reference site, so that the terminal can send the second reference signal to the ground reference site according to the second configuration information, for example, sending the second reference signal in a specific frequency band, and the ground reference site knows the second configuration information, so that the ground reference site can also receive the second reference signal in the specific frequency band, and the ground reference site can also determine the sending time of the second reference signal based on the second configuration information.

[0111] Optionally, the method further comprises:

[0112] The location of the ground reference site is sent to the terminal.

[0113] In one embodiment, the ground reference site may also send the location of the ground reference site to the terminal, so that the terminal can determine the absolute location of the terminal according to the first reference signal and the location of the ground reference site.

[0114] Optionally, the terrestrial reference site is located at an edge of a serving cell in the non-terrestrial network.

[0115] In one embodiment, when a terminal is located at the edge of a service cell in a non-terrestrial network, it is more likely to need to report its own location. In this case, a ground reference station can be set at the edge of the service cell in the non-terrestrial network to exchange reference signals with the terminal that needs to report its location.

[0116] Fig.15 FIG. 1 is a schematic flow chart of another method for determining a position according to an embodiment of the present disclosure. Fig.15 As shown, determining the position of the terminal according to the second reference signal includes:

[0117] In step S2113, determining a first measurement result of receiving the second reference signal, and obtaining a second measurement result of receiving the second reference signal at other ground reference sites;

[0118] In step S2114, the location of the terminal is determined according to the first measurement result and the second measurement result.

[0119] In one embodiment, the first measurement result and the second measurement result may be a receiving time, a receiving angle, a signal strength, etc., when the ground reference station receives the second reference signal.

The number of second receiving times is the same as the number of other ground reference sites, which can be one or more. Then, the ground reference site A can determine the position of the terminal based on the first receiving time and the second receiving time.
