[0099] Please refer to Figure 1 , which shows a schematic structural diagram of a wireless communication system provided by the embodiments of the present disclosure. As Figure 1 shown, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: a plurality of terminals 11 and a plurality of base stations 12.

[0100] Among them, the terminal 11 can be a device that provides voice and / or data connectivity to the user. The terminal 11 can communicate with one or more core networks via a Radio Access Network (RAN). The terminal 11 can be an Internet of Things (IoT) terminal, such as a sensor device, a mobile phone (or called a "cellular" phone), and a computer with an IoT terminal. For example, it can be a fixed, portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted device. For example, a Station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a User Equipment (UE).

Alternatively, the base station 12 can also be a gNode B (gNB) with a centralized distributed architecture adopted in a 5G system. When the base station 12 adopts a centralized distributed architecture, it generally includes a central unit (CU) and at least two distributed units (DUs). The protocol stacks of the Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, and Media Access Control (MAC) layer are set in the central unit; the protocol stack of the Physical (PHY) layer is set in the distributed unit. The specific implementation manner of the base station 12 in the embodiments of the present disclosure is not limited.

In different embodiments, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; alternatively, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as the new air interface; or the wireless air interface can also be a wireless air interface based on the standard of the next-generation mobile communication network technology of 5G.

Among them, the network management device 13 may be a core network device in a wireless communication system. For example, the network management device 13 may be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, the network management device may also be other core network devices, such as a Serving GateWay (SGW), a Public Data Network GateWay (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS), etc. The embodiments of the present disclosure do not limit the implementation form of the network management device 13.

[0107] The execution subjects involved in the embodiments of the present disclosure include but are not limited to: user equipment (UE, User Equipment) in a cellular mobile communication system, and base stations of cellular mobile communication, etc.

[0108] As Figure 2 shown, this exemplary embodiment provides a location determination method, which is applied to a terminal such as a UE in a communication system. The location determination method may include:

[0109] Step 201: Send a first ranging request to the base station; wherein, the first ranging request carries an identifier associated with a second UE, and wherein the first ranging request is at least associated with ranging between the base station and the second UE.

[0110] Step 202: Receive first ranging information associated with the first ranging request from the base station.

[0111] Here, the communication system may be a cellular mobile communication system. The base station may be a base station in a cellular mobile communication system. The first UE and the second UE may be UE such as mobile phone terminals in a cellular mobile communication system. The first UE and the second UE may be two UEs resident on the same base station.

[0112] The first ranging request may be relative position request information. The first UE may send a first ranging request to the base station. After receiving the first ranging request, the base station may at least determine the relative position between the second UE and the base station.

[0113] By ranging, the relative position between two devices can be obtained, and the relative position may include the distance between two communication devices, the angle between the straight line connecting the two communication devices and a reference line, etc. Here, the communication devices include: a first UE, a second UE, or a base station.

[0114] The relative position between the second UE and the base station can be determined by the base station based on the position information of the base station and the position information of the second UE. For example, it can be determined according to the position information of the base station and the position information of the second UE reported by the second UE, where the position information of the second UE can be determined by the second UE using GPS. The relative position between the second UE and the base station can also be determined by the base station through the radio signals of cellular mobile communication.

[0115] In an alternative embodiment, the base station can pre-determine the relative position between itself and the second UE (e.g., periodically, or when the UE initially accesses), and save the associated result in the memory device of the base station. Thus, when receiving a first ranging request, the base station can directly send the relative position information between the base station and the second UE stored in the memory device to the first UE as the first ranging information.

[0116] The base station can also use methods such as TOF to determine the distance between the second UE and the base station, and determine the relative position between the second UE and the base station according to the arrival angle of the signal sent by the second UE.

[0117] The first ranging request may also carry the identifier of the first UE. When the first ranging request has both the identifier of the first UE and the identifier of the second UE. The base station can determine the two UEs for which the relative position needs to be determined. The base station can respectively confirm the relative position with the first UE and the relative position with the second UE, and then determine the relative position between the first UE and the second UE. The base station can also send ranging signals for measuring TOF to the first UE and the second UE respectively.

[0118] The base station and the UE can pre-agree on the operations indicated by the identifier of the UE carried in the first ranging request. For example, when the first ranging request only carries the identifier of the second UE, it can indicate that the first UE determines the relative position between the first UE and the second UE, and the base station only needs to provide the relative position between the base station and the second UE to the first UE.

[0119] The first ranging information can be used by the first UE to determine the relative position between the first UE and the second UE. The first ranging information may include: the relative position information between the second UE and the base station, the relative position information between the first UE and the second UE determined by the base station, and / or the relative position information between the first UE and the base station determined by the base station, etc.

[0120] In another embodiment, the base station may determine whether it is necessary to interact with the first UE based on the identifier of the first UE in the first ranging request, and then determine the position of the first UE relative to the base station. Alternatively, it may determine whether it is necessary to interact with the first UE based on the indication carried in the first ranging request, so as to determine the position of the first UE relative to the base station.

[0121] In this way, on the one hand, relative positioning between UEs is achieved; on the other hand, there is no need to establish a communication connection between UEs, and the positioning of UEs is realized by means of the existing base station.

[0122] In one embodiment, the receiving the first ranging information associated with the first ranging request from the base station includes:

[0123] Receiving the first ranging information from the base station indicating the relative position between the first UE and the second UE.

[0124] Here, it may be specified by the communication protocol, or agreed upon by the base station and the UE, that the base station calculates the relative position between the first UE and the second UE, or the first UE calculates the relative position between the first UE and the second UE.

[0125] Exemplarily, it may be determined according to the indication in the first ranging request that the base station sends the relative position between the base station and the second UE to the UE, or the base station calculates the relative position between the first UE and the second UE and sends it to the first UE.

[0126] Alternatively, it may also be determined by the base station itself to send the relative position between the base station and the second UE to the UE, or the base station calculates the relative position between the first UE and the second UE and sends it to the first UE.

[0127] As Figure 3 shown, in the case where the relative positions of the first UE and the base station, namely the distance A and the angle α, and the relative position of the second UE and the base station, namely the distance B and the angle β, are known, the relative position between the first UE and the second UE, namely the distance C and the angle γ, can be determined based on calculation methods such as trigonometric functions.

[0128] The relative position between the first UE and the second UE may be calculated by the base station. The base station may determine the relative position between the first UE and the second UE based on the relative position between the first UE and the base station and the relative position between the second UE and the base station.

[0129] The relative position between the UE and the base station can be determined by the base station or the UE based on the location information of the base station and the location information of the UE. For example, the UE can determine the relative position between the UE and the base station according to the location information of the base station and the location information of the UE, where the location information of the UE can be determined by the UE using GPS. Alternatively, the base station can determine the relative position between the UE and the base station according to the location information reported by the UE. The relative position between the UE and the base station can also be determined by the base station through existing positioning methods. Among them, the UE can include: the first UE and / or the second UE.

[0130] The relative position between the first UE and the base station, and the relative position between the second UE and the base station can also be determined by measuring the signals between the base station and the UE, etc.

[0131] Exemplarily, the base station receives a first ranging request. The base station determines the relative position between the first UE and the second UE according to the relative position between the first UE and the base station, and the relative position between the second UE and the base station, and sends the relative position between the first UE and the second UE to the first UE through the first ranging information.

[0132] In this way, in the case where the first UE and the second UE do not establish a direct communication connection, the UE obtains the relative position between the first UE and the second UE from the base station, reducing the complexity brought about by the first UE and the second UE establishing a direct communication connection, and improving the efficiency of the first UE determining the relative position between the first UE and the second UE.

[0133] In one embodiment, the method further includes:

[0134] Determine the relative position between the first UE and the base station according to the reception parameters of the wireless signal between the first UE and the base station;

[0135] Send second ranging information for indicating the relative position between the first UE and the base station to the base station.

[0136] In one embodiment, the first UE can determine the distance between the first UE and the base station according to the reception parameters of the wireless signal with the base station. Here, the reception parameters can include the time of flight (TOF, Time of Fly) of the wireless signal and the arrival angle of the wireless signal, etc.

[0137] Exemplarily, the first UE can determine the distance between the first UE and the base station by measuring the signal TOF. One implementation of TOF can be: the base station can send a positioning signal to the first UE, and the positioning signal can carry the transmission time when the base station sends the positioning signal. The first UE can determine the time of flight of the positioning signal based on the reception time of the received positioning signal and the transmission time of the sent positioning signal, and further determine the distance between the first UE and the base station.

[0138] In another example, the first UE sends a positioning signal, such as the first ranging request, to the base station. After receiving the positioning signal, the base station sends a response message to the first UE, and the response message includes the response delay of the positioning signal. After receiving the response message, the first UE can determine the flight time of the signal based on the time when the positioning signal is sent, the time when the response message is received, and the response delay, and then determine the distance between the first UE and the base station.

[0139] The first UE can also determine the angle of arrival of the positioning signal based on the reception time difference of different antennas of the first UE and the distance between each antenna.

[0140] Combine the distance between the first UE and the base station and the angle of arrival of the positioning signal to determine the relative position between the first UE and the base station.

[0141] When the base station determines the relative position between the first UE and the second UE, the first UE can send the relative position between the first UE and the base station determined by itself to the base station in the form of the second ranging information.

[0142] In another embodiment, the reception parameter may also be the reception power and the reception angle.

[0143] The first UE can determine the attenuation during the transmission of the positioning signal based on the transmission power of the positioning signal transmitted by the base station and the reception power of the positioning signal received by the first UE, so as to determine the distance from the first UE to the base station. The first UE can also determine the angle of arrival of the positioning signal based on the reception time difference of different antennas of the first UE and the distance between each antenna. Combine the distance between the first UE and the base station and the angle of arrival of the positioning signal to determine the relative position between the first UE and the base station.

[0144] In one embodiment, receiving the first ranging information associated with the first ranging request from the base station includes:

[0145] Receiving the first ranging information from the base station indicating the relative position between the second UE and the base station;

[0146] The method further includes:

[0147] Based on the relative position between the first UE and the base station and the relative position between the second UE and the base station obtained according to the ranging, determine the relative position between the first UE and the second UE.

[0148] The relative position between the first UE and the second UE can be calculated by the first UE. The base station can determine the relative position between the first UE and the second UE based on the relative position between the first UE and the base station and the relative position between the second UE and the base station.

[0149] The relative position between the first UE and the base station can be determined by the first UE based on its own position and the position of the base station sent by the base station. The relative position between the first UE and the base station can also be determined based on the measurement results of the signals between the base station and the first UE, etc.

[0150] The relative position between the second UE and the base station can be sent by the base station to the first UE. Here, the relative position between the second UE and the base station can be determined by the base station based on the geographical coordinate positions of the base station and the second UE, or can be determined by the base station based on the measurement results of the signals between the base station and the second UE, etc., or can also be determined by the second UE and then sent to the base station.

[0151] Exemplarily, the base station can determine the distance between the second UE and the base station by measuring the signal TOF. One implementation manner of TOF can be: the base station can send a positioning signal to the second UE, and the positioning signal can carry the sending time when the base station sends the positioning signal. The second UE can determine the flight time of the positioning signal based on the reception time of the received positioning signal and the sending time of the sent positioning signal, and then determine the distance between the second UE and the base station.

[0152] Exemplarily, the base station receives a first ranging request, determines the relative position between the second UE and the base station, and determines the relative position between the first UE and the second UE in combination with the relative position between the first UE and the base station.

[0153] In the process of determining the relative position between the first UE and the second UE, there is no need to establish a direct communication connection between the first UE and the second UE. Thus, there is no need for an additional communication protocol to coordinate the direct communication connection between the first UE and the second UE, and there is no need to consider whether the signal quality between the first UE and the second UE can meet the requirements of direct communication with each other. Thus, in the case where the first UE and the second UE do not establish a direct communication connection, the first UE obtains the relative position between the second UE and the base station from the base station, and then combines the relative position between the first UE and the base station to determine the relative position between the first UE and the second UE, reducing the complexity brought about by the need to establish a direct communication connection between the first UE and the second UE, and improving the efficiency of the first UE to determine the relative position between the first UE and the second UE.

[0154] In one embodiment, the method further includes:

[0155] Determine the relative position between the first UE and the base station according to the reception parameters of the wireless signal between the first UE and the base station.

[0156] When the first UE calculates the relative position between the first UE and the second UE, the first UE can determine the relative position between the first UE and the base station based on the reception parameters of the wireless signal between the first UE and the base station;

[0157] The first UE may determine the distance between the first UE and the base station according to the reception parameters of the wireless signal between the first UE and the base station. Here, the reception parameters may include the time of flight (TOF) of the wireless signal, the angle of arrival of the wireless signal, etc.

[0158] Exemplarily, the first UE may determine the distance between the first UE and the base station by measuring the signal TOF. One implementation of TOF may be: the base station may send a positioning signal to the first UE, and the positioning signal may carry the transmission time when the base station sends the positioning signal. The first UE may determine the time of flight of the positioning signal based on the reception time of the received positioning signal and the transmission time of the sent positioning signal, and then determine the distance between the first UE and the base station.

[0159] In another example, the first UE sends a positioning signal to the base station, such as the first ranging request. After receiving the positioning signal, the base station sends a response message to the first UE, and the response message includes the response delay for the positioning signal. After receiving the response message, the first UE may determine the time of flight of the signal based on the time of sending the positioning signal, the time of receiving the response message, and the response delay, and then determine the distance between the first UE and the base station.

[0160] The first UE may also determine the angle of arrival of the positioning signal according to the reception time difference of different antennas of the first UE and the distance between each antenna.

[0161] Combine the distance between the first UE and the base station and the angle of arrival of the positioning signal to determine the relative position between the first UE and the base station.

[0162] In one embodiment, the method further includes:

[0163] Receiving third ranging information determined by the base station according to the reception parameters of the wireless signal between the first UE and the base station, where the third ranging information is used to indicate the relative position between the first UE and the base station.

[0164] When the first UE calculates the relative position between the first UE and the second UE, the relative position between the first UE and the base station may be sent by the base station to the first UE through the third ranging information.

[0165] The base station may determine the distance between the first UE and the base station on the base station side according to the reception parameters of the wireless signal between the base station and the first UE. Here, the reception parameters may include the TOF of the wireless signal, the angle of arrival of the wireless signal, etc. The method used by the base station to determine the relative position between the first UE and the base station is similar to the method used by the first UE to determine the relative position between the first UE and the base station, and will not be elaborated here.

[0166] Such asFigure 4 As shown, this exemplary embodiment provides a location determination method, which is applied to a base station in a communication system. The location determination method may include:

[0167] Step 401: Receive a first ranging request from a first user equipment (UE). The first ranging request carries an identifier associated with a second UE, and the first ranging request is at least associated with ranging between the base station and the second UE.

[0168] Step 402: In response to the first ranging request, send first ranging information to the first UE.

[0169] Here, the communication system may be a cellular mobile communication system. The base station may be a base station in the cellular mobile communication system, and the first UE and the second UE may be UE such as mobile phone terminals in the cellular mobile communication system. The first UE and the second UE may be two UEs resident in the same base station.

[0170] The first ranging request may be relative position request information. The first UE may send the first ranging request to the base station. After receiving the first ranging request, the base station may at least determine the relative position between the second UE and the base station.

[0171] Through ranging, the relative position between two devices can be obtained, and the relative position may include the distance between two communication devices, and the angle between the straight line connecting the two communication devices and a reference line, etc. Here, the communication devices include: the first UE, the second UE or the base station.

[0172] The first ranging request may also carry an identifier of the first UE. When the first ranging request has both the identifier of the first UE and the identifier of the second UE, the base station may determine the two UEs for which the relative position needs to be determined. The base station may respectively confirm the relative position with the first UE and the relative position with the second UE, and then determine the relative position between the first UE and the second UE. The base station may also respectively send ranging signals for measuring the time of flight (TOF) to the first UE and the second UE.

[0173] The base station and the UE may pre - agree on the operations indicated by the identifier of the UE carried in the first ranging request. For example, when the first ranging request only carries the identifier of the second UE, it may indicate that the first UE determines the relative position between the first UE and the second UE, and the base station only needs to provide the relative position between the base station and the second UE to the first UE.

[0174] The first ranging information may be used by the first UE to determine the relative position between the first UE and the second UE. The first ranging information may include: the relative position information between the second UE and the base station, the relative position information between the first UE and the second UE determined by the base station, and / or the relative position information between the first UE and the base station determined by the base station, etc.

[0175] In another embodiment, the base station may determine whether it is necessary to interact with the first UE based on the identifier of the first UE in the first ranging request, and then determine the position of the first UE relative to the base station. Or determine whether it is necessary to interact with the first UE according to the indication carried in the first ranging request, so as to determine the position of the first UE relative to the base station.

[0176] In this way, on the one hand, relative positioning between UEs is achieved, and on the other hand, there is no need to establish a communication connection between UEs, and the positioning of UEs is realized by means of the existing base station.

[0177] In one embodiment, the method further includes:

[0178] According to the first ranging request, perform ranging between the base station and the second UE to obtain the relative position between the second UE and the base station.

[0179] The relative position between the second UE and the base station can be determined by the base station based on the position information of the base station and the position information of the second UE. For example, it can be determined according to the position information of the base station and the second UE position information reported by the second UE, where the position information of the second UE can be determined by the second UE using GPS. The relative position between the second UE and the base station can also be determined by the base station through the radio signal of cellular mobile communication.

[0180] The base station can also use methods such as TOF to determine the distance between the second UE and the base station, and determine the relative position between the second UE and the base station according to the arrival angle of the signal sent by the second UE.

[0181] In an alternative embodiment, the base station may pre-determine its relative position with the second UE (for example, periodically, or when the UE initially accesses), and save the associated result in the memory device of the base station. Thus, when receiving the first ranging request, the base station can directly send the relative position information between the base station and the second UE stored in the memory device to the first UE as the first ranging information.

[0182] In one embodiment, the method further includes:

[0183] Based on the relative position between the first UE and the base station, and the relative position between the second UE and the base station, determine the relative position between the first UE and the second UE;

[0184] The sending of the first ranging information to the first UE includes:

[0185] Send the first ranging information indicating the relative position between the first UE and the second UE to the first UE.

[0186] Here, it can be specified by the communication protocol or agreed upon by the base station and the UE that the base station calculates the relative positions of the first UE and the second UE, or the first UE calculates the relative positions of the first UE and the second UE.

[0187] Exemplarily, it can be determined according to the indication in the first ranging request that the base station sends the relative position between the base station and the second UE to the UE, or the base station calculates the relative position between the first UE and the second UE and sends it to the first UE.

[0188] Alternatively, it can also be determined by the base station itself to send the relative position between the base station and the second UE to the UE, or the base station calculates the relative position between the first UE and the second UE and sends it to the first UE.

[0189] As Figure 3 shown, in the case where the relative positions of the first UE and the base station, namely the distance A and the angle α, and the relative positions of the second UE and the base station, namely the distance B and the angle β, are known, the relative positions of the first UE and the second UE, namely the distance C and the angle γ, can be determined based on calculation methods such as trigonometric functions.

[0190] The base station can calculate the relative positions of the first UE and the second UE. The base station can determine the relative positions of the first UE and the second UE based on the relative positions of the first UE and the base station and the relative positions of the second UE and the base station.

[0191] The relative positions between the UE and the base station can be determined by the base station or the UE based on the location information of the base station and the location information of the UE. For example, the UE can determine the relative position between the UE and the base station according to the location information of the base station and the location information of the UE, where the location information of the UE can be determined by the UE using GPS. Or, the base station can determine the relative position between the UE and the base station according to the location information reported by the UE. The relative positions between the UE and the base station can also be determined by the base station through existing positioning methods. Among them, the UE can include: the first UE and / or the second UE.

[0192] The relative positions of the first UE and the base station, and the relative positions of the second UE and the base station can also be determined through measurement results of signals between the base station and the UE, etc.

[0193] Exemplarily, the base station receives the first ranging request. The base station determines the relative positions of the first UE and the second UE based on the relative positions of the first UE and the base station and the relative positions of the second UE and the base station, and sends the relative positions of the first UE and the second UE to the first UE through the first ranging information.

[0194] Thus, in the case where the first UE and the second UE do not establish a direct communication connection, the UE obtains the relative positions of the first UE and the second UE from the base station, reducing the complexity brought about by the first UE and the second UE establishing a direct communication connection, and improving the efficiency of the first UE in determining the relative positions of the first UE and the second UE.

[0195] In one embodiment, the method further includes:

[0196] Receiving second ranging information determined by the first UE according to reception parameters of a wireless signal between the first UE and the base station, where the second ranging information is used to indicate the relative position of the first UE and the base station.

[0197] The first UE can determine the distance between the first UE and the base station according to reception parameters of a wireless signal between the first UE and the base station. Here, the reception parameters may include the time of flight (TOF) of the wireless signal, the angle of arrival of the wireless signal, etc.

[0198] Exemplarily, the first UE can determine the distance between the first UE and the base station by measuring the TOF of the signal. One implementation manner of TOF may be: the base station can send a positioning signal to the first UE, the positioning signal may carry the transmission time when the base station sends the positioning signal, and the first UE can determine the time of flight of the positioning signal based on the reception time of the received positioning signal and the transmission time of the sent positioning signal, and further determine the distance between the first UE and the base station.

[0199] The first UE can also determine the angle of arrival of the positioning signal according to the reception time difference of different antennas of the first UE and the distance between each antenna.

[0200] Combining the distance between the first UE and the base station and the angle of arrival of the positioning signal to determine the relative position of the first UE and the base station.

[0201] When the base station determines the relative positions of the first UE and the second UE, the first UE can send the relative position of the first UE and the base station determined by itself to the base station in the form of second ranging information.

[0202] In another embodiment, the reception parameters may also be reception power and reception angle.

[0203] The first UE can determine the attenuation during the transmission of the positioning signal based on the transmission power of the positioning signal transmitted by the base station and the reception power of the positioning signal received by the first UE, so as to determine the distance from the first UE to the base station. The first UE can also determine the angle of arrival of the positioning signal according to the reception time difference of different antennas of the first UE and the distance between each antenna. Combining the distance between the first UE and the base station and the angle of arrival of the positioning signal to determine the relative position of the first UE and the base station.

[0204] In one embodiment, the method further includes:

[0205] Determine the relative position between the first UE and the base station according to the reception parameters of the wireless signal between the first UE and the base station.

[0206] When the base station calculates the relative positions of the first UE and the second UE, the base station can determine the relative position between the first UE and the base station.

[0207] The base station can determine the distance between the first UE and the base station according to the reception parameters of the wireless signal with the first UE. Here, the reception parameters may include the TOF of the wireless signal, the arrival angle of the wireless signal, etc.

[0208] Exemplarily, the base station can determine the distance between the first UE and the base station by measuring the signal TOF. One implementation of TOF can be: the first UE can send a positioning signal to the base station, and the positioning signal can carry the transmission time when the first UE sends the positioning signal. The base station can determine the flight time of the positioning signal based on the reception time of the received positioning signal and the transmission time of the sent positioning signal, and then determine the distance between the first UE and the base station.

[0209] The base station can also determine the arrival angle of the positioning signal according to the reception time difference of different antennas of the base station and the distance between each antenna.

[0210] Combine the distance between the first UE and the base station and the arrival angle of the positioning signal to determine the relative position between the first UE and the base station.

[0211] In one embodiment, the sending the first ranging information to the first UE includes:

[0212] Send the first ranging information indicating the relative position between the second UE and the base station to the first UE.

[0213] The first UE can calculate the relative positions of the first UE and the second UE. The base station can determine the relative positions of the first UE and the second UE based on the relative position between the first UE and the base station and the relative position between the second UE and the base station.

[0214] The relative position between the first UE and the base station can be determined by the first UE based on its own position and the base station position sent by the base station. The relative position between the first UE and the base station can also be determined through measurement results of the signal between the base station and the first UE, etc.

[0215] The relative position of the second UE with respect to the base station can be sent by the base station to the first UE. Here, the relative position of the second UE with respect to the base station can be determined by the base station based on the location information of the base station and the second UE, or can be determined by the base station through measurement results of signals between the base station and the second UE, or can also be determined by the second UE and then sent to the base station.

[0216] Exemplarily, the base station receives a first ranging request, determines the relative position of the second UE with respect to the base station, and determines the relative position between the first UE and the second UE in combination with the relative position of the first UE with respect to the base station.

[0217] In the process of determining the relative position between the first UE and the second UE, it is not necessary to establish a direct communication connection between the first UE and the second UE. Thus, there is no need for an additional communication protocol to coordinate the direct communication connection between the first UE and the second UE, and there is no need to consider whether the signal quality between the first UE and the second UE can meet the requirements of direct communication with each other.

[0218] Thus, in the case where the first UE and the second UE do not establish a direct communication connection, the first UE obtains the relative position between the second UE and the base station from the base station, and then combines the relative position between the first UE and the base station to determine the relative position between the first UE and the second UE, reducing the complexity brought about by the need to establish a direct communication connection between the first UE and the second UE, and improving the efficiency of the first UE in determining the relative position between the first UE and the second UE.

[0219] In one embodiment, the method further includes:

[0220] Determine the relative position of the first UE with respect to the base station based on the reception parameters of the wireless signal between the first UE and the base station;

[0221] Send third ranging information indicating the relative position of the first UE with respect to the base station to the first UE.

[0222] When the first UE calculates the relative position between the first UE and the second UE, the relative position of the first UE with respect to the base station can be sent by the base station to the first UE through the third ranging information.

[0223] The base station can determine the distance between the first UE and the base station on the base station side according to the reception parameters of the wireless signal with the first UE. Here, the reception parameters can include the TOF of the wireless signal, the arrival angle of the wireless signal, etc. The method used by the base station to determine the relative position of the first UE with respect to the base station will not be elaborated here.

Here, the reception parameters may include the TOF of the wireless signal, the arrival angle of the wireless signal, etc.

[0228] Exemplarily, the base station can determine the distance between the second UE and the base station by measuring the signal TOF. One implementation of TOF can be: the base station sends a positioning signal to the second base station, and the positioning signal can carry the transmission time when the base station sends the positioning signal.

[0238] Exemplarily, the base station sends a positioning signal to the second device, such as the second ranging request. After receiving the positioning signal, the second UE sends a response message to the base station, and the response message includes the response delay to the positioning signal. After receiving the response message, the base station can determine the flight time of the signal based on the time when the positioning signal is sent, the time when the response message is received, and the response delay, and then determine the distance between the second UE and the base station.

[0246] 5. Based on the ranging information between the network and the target UE obtained by the network in 2 and 3, and the ranging information between the network and the initialization UE, the UE ranging between the initialization UE and the target UE is completed. The specific implementation methods include the following:

[0247] a) The network sends the ranging information of the network obtained in 2 and the target UE to the initialization UE. The initialization UE completes the ranging conversion calculation between the initialization UE and the target UE based on this ranging information and the ranging information obtained in step 3, and obtains the ranging information between the initialization UE and the target UE, thereby completing the UE ranging between the initialization UE and the target UE.

[0250] Step 501: UE1 sends a ranging request to gNB (the network) (UE1 is the initialization UE).

[0251] Step 502: After receiving the ranging request sent by UE1, gNB sends a ranging response message to UE1.

[0252] Step 503: After receiving the ranging request sent by UE1, gNB sends ranging request information to UE2 (the target UE); there is no requirement for the sequence of steps 502 and 503.

[0253] Step 504: After receiving the ranging response information sent by gNB, UE1 completes the ranging between UE1 and gNB.

[0254] Step 505: After receiving the ranging request sent by gNB, UE2 sends a ranging response message to gNB.

[0255] Step 506: After receiving the ranging response message sent by UE2, gNB completes the ranging between gNB and UE2.

[0256] Step 507: gNB sends the ranging information between gNB and UE2 to UE1.
