Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a terminal positioning method, device, equipment, storage medium and program product. Background Art

[0002] In the 3rd Generation Partnership Project (3GPP), various RAT-dependent positioning methods are defined, the basic principle of which is to use multiple base stations to locate a terminal. For example, in the Observed Time Difference of Arrival (OTDOA) positioning method, multiple base stations send positioning reference signals (PRS) to the terminal, and the terminal detects the PRS arrival time difference sent by adjacent base stations and sends the detected arrival time difference to the positioning server. The positioning server performs positioning calculation based on the location of the base station and the arrival time difference fed back by the terminal to determine the location of the terminal.

[0003] In the existing technical solutions, the positioning of the terminal depends on the positions of multiple base stations and the measurement of the PRS of the base stations. If the relative position between two terminals is to be determined, the positioning delay using this solution is relatively large. Summary of the invention

Among them, the method and the device are based on the same application concept.

The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0137] The terminal device involved in the embodiment of the present application may be a device that provides voice and / or data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device may be called a user equipment (UE).

In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be arranged geographically separately. The network device involved in the embodiments of the present application may also be a core network device.

[0139] Currently, 3GPP defines various RAT-dependent positioning methods, the basic principle of which is to use multiple base stations to locate a terminal. For example, multiple base stations send PRS to the terminal, and the terminal detects the arrival time difference of the PRS sent by adjacent base stations, and sends the detected arrival time difference to the positioning server, which performs positioning calculation based on the location of the base station and the arrival time difference fed back by the terminal to determine the location of the terminal. For example, the positioning server can be a base station or a location management function (LMF).

[0140] For scenarios where the relative position relationship between terminals needs to be determined, such as the relative position relationship between vehicles in V2X scenarios, if the above positioning method is used, the network equipment needs to calculate the position of each terminal device separately, and then further determine the relative position between the two terminals, and then notify the relative position to each terminal separately. Using this method, the positioning process is complicated and the delay is large.

[0141] An embodiment of the present application provides a terminal positioning method, which implements direct positioning between two terminals based on a sidelink (SL) between the terminals. Figure 1 This is an application scenario diagram of the terminal positioning method provided in the embodiment of the present application. Figure 1 As shown in the figure, in addition to communicating with the base station 10, the first terminal 11 and the second terminal 12 can also communicate with each other using a direct link. In this way, the first terminal 11 and the second terminal 12 can achieve positioning by transmitting a positioning reference signal (SL PRS) of the direct link.

[0142] Figure 2 The flowchart of the method for positioning a terminal provided in one embodiment of the present application is as follows. Figure 2 As shown, the method includes:

[0143] S201. A first terminal determines a target positioning reference signal.

[0144] S202: The first terminal sends a target positioning reference signal to the second terminal through a direct link.

[0145] S203: The second terminal determines a relative distance between the second terminal and the first terminal according to the target positioning reference signal.

[0146] In this embodiment, the first terminal is a sending terminal, and the second terminal is a receiving terminal. In order to realize the positioning of the first terminal by the second terminal, the first terminal sends a target positioning reference signal to the second terminal through a direct link, and the direct link is a wireless path established between the first terminal and the second terminal. The target positioning reference signal is determined by the first terminal, and the method for determining the target positioning reference signal by the first terminal in the embodiment of the present application is not limited.

[0147] The second terminal receives the target positioning reference signal sent by the first terminal through the direct link, and determines the relative distance between the second terminal and the first terminal according to the target positioning reference signal, that is, the second terminal performs positioning according to the received target positioning reference signal. It should be noted that the method for the second terminal to perform positioning according to the target positioning reference signal can be a downlink arrival time difference (DownLoad-Time Difference of Arrival, DL-TDOA) method, a round trip time (RoundTrip Time, RTT) method, an angle of arrival (Angle-of-Arrival, AOA) method, etc., and the embodiment of the present application is not limited to this.

[0148] By directly sending a positioning reference signal to the second terminal through the first terminal, the second terminal can directly determine the relative distance between the second terminal and the first terminal according to the positioning reference signal. Compared with the method of relying on the base station to locate the terminal in the prior art, the positioning method provided in the embodiment of the present application has a simple positioning process and a small delay.

[0149] On the other hand, for scenarios where the terminal is not within the coverage of the base station, the existing methods cannot locate the terminal. However, the method in the embodiment of the present application does not rely on the base station and can achieve positioning through a direct link between terminals, while also saving resource overhead.

[0150] In addition, when the distance between two terminals is close, for example, the distance between vehicles in a V2X scenario is close, there is often a Line of Sight (LOS) path between the two terminals. Therefore, the channel quality of the direct link between the two terminals is better, and the channel quality of the direct link is better than the channel quality between the terminal and the base station. Therefore, the positioning result obtained by using the positioning reference signal of the direct link is also more accurate.

[0151] Still taking the V2X scenario as an example, when positioning is performed through a direct link between vehicles or between vehicles and user terminals, the relative positions between vehicles or user terminals will continue to change as the vehicles or users are moving. In order to avoid collisions, vehicles need to send positioning reference signals so that other vehicles can locate the vehicle, and they also need to be able to measure the positioning reference signals of adjacent vehicles to determine the relative positions of surrounding vehicles or users and the vehicle. Therefore, the vehicle-mounted terminal as the transmitter needs to determine the target positioning reference signal to be sent, and the vehicle-mounted terminal as the receiver needs to know which positioning reference signals need to be measured in order to perform the measurement, and perform positioning based on the measured positioning reference signals.

[0152] When the terminal is positioned through a direct link, two methods can be used to implement it. One is a radio resource control (Radio Resource Control, RRC) connection that is not based on the direct link. For example, no RRC connection for a direct link is established between the terminals, or an RRC connection for a direct link is established between the terminals, but the positioning is not based on the RRC signaling interaction of the direct link; the other is that an RRC connection for a direct link is established between the terminals, and the positioning is based on the RRC signaling interaction of the direct link. The following describes how the first terminal determines the target positioning reference signal and how the second terminal measures the positioning reference signal in these two implementation methods.

[0153] Method 1

[0154] In an implementation manner in which positioning is performed based on an RRC connection that is not based on a direct link, the first terminal determines a target positioning reference signal, including:

[0155] The first terminal obtains configuration information of a positioning reference signal, where the configuration information of the positioning reference signal is used to indicate a positioning reference signal resource pool; and determines a target positioning reference signal according to the configuration information of the positioning reference signal.

[0156] Among them, the configuration information of the positioning reference signal can be pre-configured and / or configured by the network device, and the configuration information of the positioning reference signal can indicate the positioning reference signal resource pool, or the positioning reference signal resource range, to the first terminal by direct indication or indirect indication. Among them, indirect indication refers to the calculation of the positioning reference signal resource pool based on other information. By limiting the positioning reference signal resource pool, the second terminal, that is, the receiving terminal, can detect limited positioning reference signals and reduce the detection complexity. The configuration information of the positioning reference signal may include one or more of the time-frequency resources, sequence resources, antenna resources, and spatial information of the positioning reference signal.

[0157] Optionally, the first terminal sends location information and / or direction information to the network device, and receives configuration information of a positioning reference signal determined by the network device based on the location information and / or direction information.

[0158] For example, the location information includes information about the zone to which the first terminal belongs, and the direction information may include information about the synchronization signal and PBCH block (SSB) Index. The positioning reference signal resource pool may vary depending on the zone in which the terminal is located. For example, the first terminal reports to the network device the zone to which the first terminal belongs, the network device determines the positioning reference signal resource pool corresponding to the zone to which the first terminal belongs, and sends the corresponding positioning reference signal configuration information to the first terminal, so that the first terminal can determine the target reference signal to be sent according to the configuration information of the positioning reference signal.

[0159] It should be noted that in order to increase the orthogonality of the positioning reference signal, the positioning reference signal can be reused in different areas, that is, the positioning reference signals included in the positioning reference signal resource pools corresponding to different areas can be the same. The positioning reference signals already used and the available positioning reference signals in each area are different. The network device can update the available positioning reference signals in each area according to the area where the terminal is located and the use of the positioning reference signal.

[0160] Optionally, the first terminal receives configuration information of a positioning reference signal broadcast by a network device.

[0161] The network device can broadcast configuration information of positioning reference signals corresponding to different areas to indicate positioning reference signal resource pools corresponding to different areas. The first terminal can determine the positioning reference signal resource pool corresponding to the area to which the first terminal belongs based on the received broadcast information, so as to determine the target positioning reference signal to be sent.

[0162] Optionally, the first terminal obtains configuration information of a preconfigured positioning reference signal. The configuration information of the preconfigured positioning reference signal may be specified in a protocol, and the first terminal may determine a positioning reference signal resource pool according to the protocol to determine a target positioning reference signal to be sent.

[0163] For example, when the first terminal is outside the coverage area of ​​the network device, the first terminal cannot receive the configuration information of the positioning reference signal sent by the network device. At this time, the first terminal can use the configuration information of the preconfigured positioning reference signal to determine the target positioning reference signal. It is understandable that before measuring the positioning reference signal, the second terminal can determine the positioning reference signal to be measured according to the configuration information of the preconfigured positioning reference signal, such as the preconfigured positioning reference signal resource pool.

[0164] Optionally, when the first terminal is within the coverage area of ​​the network device, the first terminal may send a target positioning reference signal according to the configuration information of the positioning reference signal configured by the network device, and may also send a target positioning reference signal according to the configuration information of the pre-configured positioning reference signal.

[0165] The positioning reference signal indicated in the configuration information of the preconfigured positioning reference signal may be related to the terminal identifier (UEID). Optionally, the terminal identifier may include a source identifier (Source_ID) and / or a destination identifier (Destination_ID). When sending a positioning reference signal, the preconfigured configuration information for sending a positioning reference signal may be determined according to the source identifier. When receiving a positioning reference signal, the preconfigured configuration information for receiving a positioning reference signal may be determined according to the destination identifier.

[0166] In specific applications, the configuration information of the pre-configured positioning reference signal can be used according to the usage scenario to determine the target positioning reference signal to be sent according to the source identifier or the destination identifier. For example, when there is a central node between the first terminal and the second terminal, the first terminal can use the identifier of the central node as the source identifier to determine the target positioning reference signal. For another example, in the scenario of automatic parking, the electric charging pile of the parking space can send the target positioning reference signal according to the identifier of the vehicle terminal as the destination identifier.

[0167] Optionally, the positioning reference signal resource pool indicated by the configuration information of the preconfigured positioning reference signal is different from the positioning reference signal resource pool indicated by the configuration information of the positioning reference signal configured by the network device. Optionally, the priority of the configuration information of the positioning reference signal configured by the network device is higher than the configuration information of the preconfigured positioning reference signal. When the first terminal accesses the network and receives the configuration information of the positioning reference signal sent by the network device, the first terminal determines the target positioning reference signal to be sent according to the configuration information of the positioning reference signal sent by the network device. When the first terminal cannot receive the configuration information of the positioning reference signal sent by the network device, the first terminal determines the target positioning reference signal to be sent according to the configuration information of the preconfigured positioning reference signal. Optionally, the configuration information of the positioning reference signal configured by the network device and the priority of the configuration information of the preconfigured positioning reference signal can be configured by the network device. That is, the network device specifies that the first terminal adopts the configuration information of the positioning reference signal configured by the network device or the configuration information of the preconfigured positioning reference signal.

[0168] In any of the above examples, after acquiring the configuration information of the positioning reference signal, the first terminal may determine the target positioning reference signal to be sent according to the positioning reference signal resource pool indicated by the configuration information of the positioning reference signal. For example, the first terminal selects a positioning reference signal from the positioning reference signal resource pool and determines it as the target positioning reference signal for sending.

[0169] For example, when a vehicle is driving on the road, the vehicle terminal needs to detect the front and rear vehicles in the same lane. The positioning reference signal can be bound to the lane, and the vehicle terminal sends the positioning reference signal corresponding to the current lane for other vehicles to detect. When the vehicle needs to insert into the adjacent lane, during the insertion process, the vehicle terminal needs to send the positioning reference signal corresponding to the inserted lane and the original lane.

[0170] Optionally, when two first terminals select the same target positioning reference signal to send, the two first terminals cannot detect each other. To solve this problem, the first terminals may randomly select some moments not to send the target positioning reference signal, and perform positioning reference signal detection at these moments. Since the probability that the moments randomly selected by the two first terminals for not sending the target positioning reference signal are the same is low, the problem of being unable to measure positioning due to a collision of the target positioning reference signal can be avoided.

[0171] Optionally, based on the above, the moment selected by the first terminal for not sending the target positioning reference signal may be related to the identifier of the first terminal, thereby further reducing the probability that the two first terminals select the same moment for not sending the target positioning reference signal, thereby avoiding the problem of being unable to measure positioning due to a collision of target positioning reference signal resources.

[0172] Optionally, each terminal may have a number (Zone ID) within the area, and the moment when the first terminal selects not to send the target positioning reference signal may be related to the Zone ID. This may also reduce the probability that the two first terminals select the same moment when not to send the target positioning reference signal, thereby avoiding the problem of being unable to measure and position due to a collision of target positioning reference signal resources.

[0173] Optionally, the first terminal may detect positioning reference signals of surrounding terminals, and select an undetected positioning reference signal from a positioning reference signal resource pool as a target positioning reference signal, thereby avoiding positioning reference signal resource collision.

[0174] Optionally, the first terminal may also report the selected target positioning reference signal to the network device, so that the network device can determine the positioning reference signal used by each terminal, and then update the available positioning reference signal resource pool. Optionally, the first terminal may also send a positioning request to the network device while reporting the target positioning reference signal, so that the network device starts a processing flow related to positioning.

[0175] Optionally, the first terminal selects a positioning reference signal from a positioning reference signal resource pool and reports the selected positioning reference signal to the network device. If confirmation information returned by the network device is received, the selected positioning reference signal is determined as the target positioning reference signal. The confirmation information is used to indicate that the positioning reference signal selected by the first terminal is available.

[0176] Since the positioning reference signals selected by different terminals may be the same, in order to avoid collision, the network device may confirm whether the positioning reference signal selected by the first terminal is available. If available, the network device sends confirmation information to the first terminal. If not available, the network device may not return confirmation information to the first terminal, or the network device may also send information to the first terminal indicating that the selected target reference signal is unavailable. If the first terminal device does not receive confirmation information after reporting the selected positioning reference signal, it reselects the positioning reference signal until the confirmation information is received.

[0177] If the two terminals select positioning reference signals and report their respective selected positioning reference signals to the network device, and the network device determines that the positioning reference signals selected by the two terminals are the same, the network device may send confirmation information only to one of the terminals, or may not send confirmation information to both terminals.

[0178] The network device may update the positioning reference signal resource pool according to the positioning reference signal reported by the first terminal. For example, after the first terminal reports the selected positioning reference signal, the network device determines that the positioning reference signal has not been selected by other terminals, and therefore returns confirmation information to the first terminal, and at the same time removes the positioning reference signal from the positioning reference signal resource pool, and notifies the new positioning reference signal resource pool to other terminals, so that other terminals can select an available positioning reference signal from it.

[0179] In this positioning method of the RRC connection not based on the direct link, the second terminal receives the target positioning reference signal sent by the first terminal through the direct link, including:

[0180] The second terminal obtains configuration information of the positioning reference signal to be measured, where the target positioning reference signal is any one of the positioning reference signals to be measured; and receives the target positioning reference signal according to the configuration information of the target positioning reference signal.

[0181] In order to perform effective positioning reference signal measurement, the second terminal needs to know which positioning reference signals need to be measured, that is, the second terminal needs to obtain the configuration information of the positioning reference signals of the terminals near it, and the configuration information of the positioning reference signals can be pre-configured and / or configured by the network device. By limiting the positioning reference signals to be measured, the second terminal can detect limited positioning reference signals, reducing the detection complexity.

[0182] Optionally, the second terminal sends location information and / or direction information to the network device, and receives configuration information of the positioning reference signal to be measured determined by the network device according to the location information and / or direction information. Optionally, the location information of the second terminal includes information of the area to which the second terminal belongs.

[0183] The second terminal reports the area to which the second terminal belongs to the network device. The network device can determine the positioning reference signal resource pool corresponding to the area to which the second terminal belongs and / or the adjacent area to which the second terminal belongs as the positioning reference signal to be measured, and send the corresponding configuration information to the second terminal, so that the second terminal can receive the positioning reference signal to be measured according to the configuration information of the positioning reference signal to be measured, which includes the target positioning reference signal sent by the first terminal.

[0184] For example, the second terminal reports the area to which the second terminal belongs to the network device. The network device uses the positioning reference signal sent by the terminal in the same area as the positioning reference signal to be measured according to the area to which the second terminal belongs, and sends its configuration information to the second terminal.

[0185] The positioning reference signal to be measured sent by the network device to the second terminal may indicate the positioning reference signal to be measured by direct indication or indirect indication. For example, the network device sends the configuration information corresponding to the full set of the positioning reference signal resource pool and the set of available positioning reference signals determined according to the area to which the second terminal belongs to the second terminal, so that the second terminal can determine the positioning reference signal to be measured according to the difference between the full set of the positioning reference signal resource pool and the set of available positioning reference signals.

[0186] Optionally, the second terminal receives configuration information of the positioning reference signal to be measured broadcast by the network device.

[0187] The network device can broadcast the configuration information of the positioning reference signal corresponding to different areas, which is used to indicate the positioning reference signal resource pools corresponding to different areas. The second terminal can determine the positioning reference signal resource pool corresponding to the area to which the second terminal belongs based on the received broadcast information, and determine it as the positioning reference signal to be measured to facilitate reception measurement.

[0188] Optionally, the second terminal obtains configuration information of a pre-configured positioning reference signal to be measured.

[0189] For example, the configuration information of the pre-configured positioning reference signal may be specified in the protocol, and the second terminal may determine the configuration information of the positioning reference signal to be measured, such as the resource pool of the positioning reference signal to be measured, according to the provisions of the protocol, so as to facilitate the positioning reference signal reception measurement.

[0190] When the second terminal is outside the coverage area of ​​the network device, the second terminal cannot receive the configuration information of the positioning reference signal to be measured issued by the network device. At this time, the second terminal can use the pre-configured configuration information of the positioning reference signal to be measured. It can be understood that before measuring the positioning reference signal, the second terminal can determine the positioning reference signal to be measured based on the configuration information of the pre-configured positioning reference signal, such as the pre-configured positioning reference signal resource pool. In this case, if the first terminal located in the coverage area of ​​the network device uses the positioning reference signal resource pool configured by the network device to send the target positioning reference signal, the second terminal cannot detect the first terminal. In this case, the second terminal can report information to the network device through other terminals to notify the network device that there is a terminal outside the coverage area in the area where the second terminal is located, so that the network device can instruct the first terminal in the coverage area to use the pre-configured positioning reference signal resource pool to send the target positioning reference signal.

[0191] Optionally, when the second terminal is within the coverage area of ​​the network device, the second terminal can determine the positioning reference signal to be measured based on the configuration information of the positioning reference signal to be measured configured by the network device, and also determine the positioning reference signal to be measured based on the pre-configured configuration information of the positioning reference signal to be measured.

[0192] Combined with the above description of the first terminal sending the target positioning reference signal, optionally, in order to ensure that the first terminal can be detected by the second terminal within the coverage area and outside the coverage area of ​​the network device, and to ensure that the second terminal can detect the first terminal within the coverage area and outside the coverage area of ​​the network device, for the first terminal, when the first terminal is within the coverage area of ​​the network device, the first terminal sends the target positioning reference signal according to the configuration information of the positioning reference signal configured by the network device, and also sends the target positioning reference signal according to the configuration information of the pre-configured positioning reference signal; when the first terminal is outside the coverage area of ​​the network device, the first terminal sends the target positioning reference signal according to the configuration information of the pre-configured positioning reference signal. For the second terminal, when the second terminal is within the coverage area of ​​the network device, the second terminal determines the positioning reference signal to be measured according to the configuration information of the positioning reference signal to be measured configured by the network device, and also determines the positioning reference signal to be measured according to the configuration information of the pre-configured positioning reference signal to be measured; when the second terminal is outside the coverage area of ​​the network device, the second terminal determines the positioning reference signal to be measured according to the configuration information of the pre-configured positioning reference signal to be measured.

[0193] In combination with the foregoing, the network device instructs the first terminal to use the configuration information of the pre-configured and / or network-configured positioning reference signal to send the target positioning reference signal, and / or the network device instructs the second terminal to use the configuration information of the pre-configured and / or network-configured positioning reference signal to receive the target positioning reference signal. It should be noted that during the terminal communication process of the direct link, there may be some first terminals within the coverage of the network device and some first terminals outside the coverage of the network device. If the network device instructs the second terminal to only measure the positioning reference signal of the first terminal within the coverage of the network device or outside the coverage, the second terminal performs the measurement according to the instruction of the network device. If the network device has no instruction, the second terminal measures the positioning reference signal of both the coverage of the network device and the first terminal outside the coverage.

[0194] Method 2

[0195] In the implementation method of positioning based on the RRC connection of the direct link, before the first terminal determines the target positioning reference signal, the first terminal establishes an RRC connection of the direct link with the second terminal. That is, synchronization and RRC connection are first established between the first terminal and the second terminal, and then the first terminal determines the target positioning reference signal to be sent and sends the target positioning reference signal, and the first terminal sends positioning measurement information to the second terminal through the RRC signaling of the direct link, and the positioning measurement information is used to indicate the positioning reference signal to be measured to the second terminal, and the positioning reference signal to be measured includes the target positioning reference signal. Correspondingly, the second terminal receives the positioning measurement information sent by the first terminal through RRC signaling, and receives the target positioning reference signal according to the positioning measurement information.

[0196] In a feasible implementation manner, the positioning measurement information includes:

[0197] Configuration information of the target positioning reference signal, and / or, a timing advance for the first terminal to send the positioning reference signal.

[0198] The positioning reference signal to be measured may include one or more target positioning reference signals. For example, after determining the target positioning reference signal, the first terminal may only send configuration information related to the target positioning reference signal as positioning measurement information to the second terminal, so that the second terminal can only measure the target positioning reference signal according to the positioning measurement information. For another example, after determining the target positioning reference signal, the first terminal may send configuration information related to the positioning reference signal resource pool including the target positioning reference signal as positioning measurement information to the second terminal, so that the second terminal can measure the positioning reference signal resource pool including the target positioning reference signal as the positioning reference signal to be measured.

[0199] Optionally, the positioning measurement information includes: configuration information of the positioning reference signal to be measured, that is, configuration information of the target positioning reference signal, and / or a time advance (TA) for the first terminal to send the positioning reference signal. The second terminal can determine the time when the first terminal sends the target positioning reference signal based on the time advance for the first terminal to send the target positioning reference signal, and then determine the receiving and sending delay of the target positioning reference signal in combination with the time when the target reference signal is received, thereby determining the relative distance between the first terminal and the second terminal.

[0200] Optionally, the first terminal determines the target positioning reference signal according to a preconfigured positioning reference signal resource pool. For example, the first terminal may determine the positioning reference signal resource pool according to a protocol provision, and determine the target positioning reference signal to be sent from the positioning reference signal resource pool.

[0201] Optionally, the first terminal performs positioning reference signal detection, and determines a target positioning reference signal based on the detected positioning reference signal.

[0202] The first terminal detects surrounding positioning reference signals. The positioning reference signals detected by the first terminal are positioning reference signals used by other terminals. Therefore, the first terminal can determine a target positioning reference signal to be sent according to the used positioning reference signals.

[0203] Optionally, the target positioning reference signal is a positioning reference signal other than the detected positioning reference signal, thereby avoiding a positioning reference signal collision.

[0204] In the above implementation, after the second terminal determines the relative distance between the second terminal and the first terminal according to the target positioning reference signal, the second terminal may also report the relative distance between the second terminal and the first terminal to the network device.

[0205] Optionally, the network device may estimate the position of each terminal according to the measurement result reported by each terminal, and implement multiplexing of positioning reference signals in different areas according to the position information of the terminal.

[0206] Optionally, the network device may estimate the location of each terminal based on the measurement results reported by each terminal, and combine the terminals that are close to each other based on the location information of the terminals. Alternatively, the network device may estimate the location of the terminal based on the uplink positioning pilot signal sent by the terminal, and combine the terminals that are close to each other. Thus, the network device may send the configuration information of the positioning reference signal to the terminal based on the combination between the terminals.
