[0044] The positioning reference signal may be one or more of the following: a downlink positioning reference signal (DL-PRS), a synchronization signal block (SSB), a channel state information reference signal (CSI-RS), and a tracking reference signal (TRS). In an optional embodiment, the positioning reference signal is a signal used to assist positioning.

[0045] The following, in conjunction with the accompanying drawings, describes in detail the terminal positioning method based on the AI ​​model provided in the embodiment of the present application through some embodiments and their application scenarios.

[0046] As shown in Figure 2, terminals at the same location receive different channels at the same location due to different beams of received signals. In the example shown in Figure 2, the Reference Signal Receiving Path Power (RSRPP) or channel impulse response obtained by channel estimation based on beam 1 is shown in Figure 3; the RSRPP or channel impulse response obtained by channel estimation based on beam 2 is shown in Figure 4; and the RSRPP or channel impulse response obtained by channel estimation based on beam 3 is shown in Figure 5. If the changed channel is input into an AI model that does not take this factor into account, completely different positioning results may be obtained, resulting in a decrease in the positioning performance of the terminal.

[0047] As shown in Figure 2, the terminals at the same location receive different channels at the same location due to different positioning reference signal resources or PRS resources. In the example shown in Figure 2, the reference signal receiving path power (RSRPP) or channel impulse response obtained by channel estimation based on beam 1 can be understood as being based on PRS resource 1, as shown in Figure 3; the RSRPP or channel impulse response obtained by channel estimation based on beam 1 can be understood as being based on PRS resource 2, as shown in Figure 4; the RSRPP or channel impulse response obtained by channel estimation based on beam 3, as shown in Figure 5. If the changed channel is input into an AI model that does not take this factor into account, completely different positioning results may be obtained, resulting in a decrease in the positioning performance of the terminal.

[0048] As shown in Figure 2a, terminals at the same location receive different channels at the same location due to different received beams. In the example shown in Figure 2, the Reference Signal Receiving Path Power (RSRPP) or channel impulse response obtained by channel estimation based on receive beam 1 is shown in Figure 3; the RSRPP or channel impulse response obtained by channel estimation based on receive beam 2 is shown in Figure 4; and the RSRPP or channel impulse response obtained by channel estimation based on receive beam 3 is shown in Figure 5. If the changed channel is input into an AI model that does not take this factor into account, completely different positioning results may be obtained, resulting in a decrease in the terminal's positioning performance.

[0049] To solve the above technical problems, as shown in Figure 6, an embodiment of the present application provides a terminal positioning method 600 based on an AI model. The method can be executed by the terminal. In other words, the method can be executed by software or hardware installed in the terminal. The method includes the following steps.

[0050] S602: The terminal executes a first behavior, where the first behavior is used to determine measurement information of a positioning reference signal of the terminal or report measurement information of the positioning reference signal of the terminal; or, the first behavior includes sending beam or beam pattern information of a positioning reference signal; wherein the measurement information of the positioning reference signal is used by the AI ​​model to determine the location information of the terminal or intermediate information of the location information.

[0051] In this embodiment, the terminal may determine the measurement information of the positioning reference signal; the terminal may also determine the measurement information of the positioning reference signal and report the measurement information of the positioning reference signal.

[0052] In this embodiment, the terminal may send beam or beam pattern information of a positioning reference signal, and the beam or beam pattern information is used by the network side device to locate the terminal based on the AI ​​model.

[0053] The AI ​​model mentioned in each embodiment of the present application may be located on the terminal side or on the network side. In the case where the terminal does not report the measurement information of the positioning reference signal, the AI ​​model may be located on the terminal side, and the terminal obtains the terminal's location information or intermediate information based on the AI ​​model. The terminal may also report the location information or intermediate information, and then the network side obtains the terminal's location information. The intermediate information mentioned here may be information obtained in the intermediate process of determining the location information, and the location information can be finally obtained based on the intermediate information. In the case where the terminal reports the measurement information of the positioning reference signal, the AI ​​model may be located on the network side, and the network side obtains the terminal's location information based on the AI ​​model.

[0054] In one embodiment, the terminal reports the beam or beam pattern information on the terminal side. For example, for an AI model or uplink positioning on the network side, the terminal reports the beam or beam pattern information on the terminal side, which can be used by the network side to locate the terminal in combination with the beam or beam pattern information, so that the AI ​​model considers factors such as the beam or beam pattern information during model training or model prediction, thereby improving the positioning performance of the terminal.

[0055] In some embodiments, the terminal may further receive first information instructing the terminal to measure a positioning reference signal or report positioning reference signal measurement information. The first information may be sent by a core network device, such as a location management function (LMF). The core network device sends the first information to an access network device, which may transparently transmit the first information to the terminal. In this embodiment, the terminal may measure a positioning reference signal; the terminal may also measure a positioning reference signal and report positioning reference signal measurement information.

[0056] The first information may be used to indicate at least one of the following:

[0057] 1) Determine measurement information of a positioning reference signal based on a single antenna or multiple antennas.

[0058] 2) Determine measurement information of a positioning reference signal based on one positioning reference signal or multiple positioning reference signals.

[0059] 3) Determine measurement information of a positioning reference signal based on one receive beam or multiple receive beams.

[0060] 4) Performing the first processing or the second processing to determine the indication information of the measurement information of the positioning reference signal. The first processing and the second processing can be de-beaming processing, which is used to remove the influence of the beam pattern on the receiving side, so as to better align the training data and measurement data of the AI ​​model and improve the accuracy of positioning.

[0061] The first information may include at least one of the following:

[0062] 1) The expected angle of arrival, expected angle of reception, or uncertainty range of the positioning reference signal. This information is used to determine the measured positioning reference signal or the beam used to receive the positioning reference signal.

[0063] 2) Beam identifier used to receive or send positioning reference signals.

[0064] In some other embodiments, the first information may also indicate the angle range and uncertainty range of the uplink positioning reference signal, such as indicating the angle range of the sounding reference signal (SRS), which is used to determine the transmission beam of the uplink positioning reference signal, and is applicable to an embodiment in which the network side obtains measurement information of the uplink positioning reference signal.

[0065] The measurement information of the positioning reference signal of the terminal may include at least one of the following:

[0066] 1) First measurement information of the positioning reference signal. The first measurement information may be information used to input the AI ​​model, and specifically may be information obtained by performing a simple measurement or processing of the positioning reference signal.

[0067] 2) Intermediate measurement information of the positioning reference signal, which may be information obtained based on the first measurement information, etc., and the intermediate measurement information may be information used to input the AI ​​model; the intermediate measurement information may be information output by the AI ​​model, for example, it may be intermediate information of the position information, or position information.

[0068] 3) Receive the beam or beam pattern information of the positioning reference signal. This embodiment can input the beam or beam pattern information of the received positioning reference signal into the AI ​​model, so that the AI ​​model considers the beam or beam pattern information during model training or model prediction, thereby improving the positioning performance of the terminal.

[0069] 4) Transmitting the beam or beam pattern information of the positioning reference signal. This embodiment can input the beam or beam pattern information of the positioning reference signal into the AI ​​model, so that the AI ​​model considers the beam or beam pattern information during model training or model prediction, thereby improving the positioning performance of the terminal.

[0070] The terminal positioning method based on the AI ​​model provided in the embodiment of the present application can determine the measurement information of the positioning reference signal or report the measurement information of the positioning reference signal; or, send the beam or beam pattern information of the positioning reference signal, so that the AI ​​model can determine the terminal's position information or intermediate information based on the measurement information of the positioning reference signal, thereby realizing the terminal positioning method based on the AI ​​model and improving the positioning performance.

[0071] In one embodiment, the first measurement information of the positioning reference signal includes at least one of the following:

[0072] 1) The first measurement information of the positioning reference signal received using the first beam. The first beam may be specified by the network side device, for example, through the first information; the first beam may also be determined by the terminal based on the received signal strength, etc.

[0073] 2) First measurement information of the positioning reference signal that has undergone the first processing.

[0074] 3) The first measurement information associated with K positioning reference signals after the second processing, where K is a positive integer.

[0075] 4) First measurement information of a positioning reference signal measured using a single antenna.

[0076] In this embodiment, the first action executed by the terminal may include at least one of the following solutions 1 to 5:

[0077] Solution 1: The terminal uses the first beam to receive a positioning reference signal, and determines first measurement information of the positioning reference signal of the terminal or reports the first measurement information of the positioning reference signal of the terminal.

[0078] This embodiment uses a specified first beam to constrain the beam used by the terminal to receive or transmit positioning reference signals. At the same location, according to this rule (or the specified first beam), terminals within a certain area are forced to use the same beam to transmit or receive positioning reference signals as much as possible. This ensures that the data used in the AI ​​model's inference process is more consistent with the training data, eliminates the influence of the beam pattern, and improves positioning accuracy.

[0079] In one embodiment, the first beam is at least one of the following:

[0080] 1) Beam specified by the network-side device.

[0081] 2) A beam with a center angle within a first angular range. The first angular range is a range of expected arrival angles or expected reception angles, such as if the center angle of the beam is within the range of the expected arrival angles or expected reception angles. The first angular range may be indicated by first information.

[0082] 3) The beam whose center angle is the smallest from a second angle. The second angle is the expected angle of arrival or the expected angle of reception. The second angle may be indicated by the first information.

[0083] 4) A beam that maximizes the Reference Signal Received Power (RSRP) of the positioning reference signal.

[0084] 5) A beam that maximizes the RSRPP of the receiving path of the positioning reference signal.

[0085] 6) A beam with an angle complementary to that of the received signal.

[0086] In one embodiment, the first information includes an identifier (ID) of the first beam. For example, the first information instructs the terminal to use receive beam 1 (Rx beam ID 1) to receive the positioning reference signal, and instructs the terminal to use transmit beam 2 (Tx beam ID 2) to send the positioning reference signal. That is, the first information can be used to indicate what beam pattern the terminal uses to receive or send the positioning reference signal.

[0087] Solution 2: The terminal receives a positioning reference signal and performs a first process on the received positioning reference signal, thereby determining first measurement information of the positioning reference signal of the terminal or reporting the first measurement information of the positioning reference signal of the terminal.

[0088] The first processing mentioned in various embodiments of the present application may be de-beaming processing. The first processing may include one of the following: multiplying by a first matrix to calculate measurement information for each antenna; performing averaging or weighted averaging to determine the measurement information; and performing averaging or weighted averaging as input to the AI ​​model.

[0089] In one embodiment, the terminal performs a first process on the positioning reference signal or channel received by the second beam, the second port, or the second diversity to obtain first measurement information of the positioning reference signal. The terminal may also report the first measurement information of the positioning reference signal. The first process can be understood as de-beaming processing, which is used to remove the influence of the beam pattern on the receiving side or the beam pattern on the transmitting side, so as to better align the training data and measurement data of the AI ​​model and improve the accuracy of positioning.

[0090] In an example A, the terminal receives a positioning reference signal or a channel S through X (X is a positive integer) second beams, second ports, or second diversity reception and multiplies the first matrix to calculate a measurement result for each antenna (per antenna).

[0091] For example, the terminal receives the signal through a second beam.

[0092] For another example, the terminal receives S via X=4 second beams.

[0093] Furthermore, S is multiplied by the inverse matrix of the beam, thereby obtaining the channel or signal x on X=4 antenna ports, or removing the influence of the receiving beam.

[0094] In example B, the terminal averages or weighted averages the positioning reference signals or channels Sj received through X second beams, second ports, or second diversity to calculate the measurement results, or uses them as input to the AI ​​model, thereby removing the influence of the beam pattern on the receiving side.

[0095] The X second beams, second ports, or second diversity in this example may meet certain conditions, which include at least one of the following: 1) the X with the largest RSRPP of the first path; 2) the X with the largest RSRP.

[0096] Solution 3: The terminal receives K positioning reference signals, performs second processing on the received K positioning reference signals, determines first measurement information of the positioning reference signals of the terminal, or reports the first measurement information of the positioning reference signals of the terminal.

[0097] The second processing mentioned in various embodiments of this application may be de-beaming, which can be understood as removing the influence of the beam on the transmitting side. The second processing may include one of the following: obtaining channel information corresponding to K transmit antennas or K transmit beams based on K positioning reference signals; and averaging or weighted averaging the measurement information of the K positioning reference signals.

[0098] Optionally, in an optional embodiment of Solution 3, the terminal uses the same receiving beam to receive K positioning reference signals or positioning reference signals sent by K transmitting beams, so as to better ensure data consistency.

[0099] Optionally, the first measurement information is associated with relevant information of a receiving beam, or is associated with indication information of using the same receiving beam for receiving K positioning reference signals.

[0100] Optionally, if the first measurement information is obtained by K positioning reference signals, the terminal does not need to report the identification information of the positioning reference signal resource ID. It can be understood that by omitting the identification information of the positioning reference signal resource ID, it is indicated that the first measurement information is obtained by measuring multiple positioning reference signals.

[0101] In one embodiment, the terminal receives first information, which includes information on the beam pattern of multiple resources on the network side. Then, the terminal receives K positioning reference signals (which can be understood as K positioning reference signals sent through K beams) based on the first information and performs second processing.

[0102] Similar to the first example A of solution two, the terminal obtains the channel information corresponding to the K transmitting antennas based on the K positioning reference signals, thereby removing the beam pattern on the transmitting side of the K positioning reference signals.

[0103] Similar to the second example B of solution 2, an average or weighted average is performed based on the measurement results of the K positioning reference signals, thereby eliminating the influence of the beam pattern on the transmitting side of the K positioning reference signals.

[0104] Alternatively, the terminal performs second processing on the first measurement information of the K positioning reference signals based on relative information of the beam patterns on different signals at corresponding angles.

[0105] Solution 4: The terminal uses a single antenna to receive or send a positioning reference signal, and determines first measurement information of the positioning reference signal of the terminal or reports the first measurement information of the positioning reference signal of the terminal.

[0106] In one embodiment, the terminal receives first information, which instructs the terminal to use a single antenna (or per antenna, canceling the transmission diversity indication) to receive or send a positioning reference signal, thereby ensuring that the beam pattern on the terminal side is not used to receive or send the positioning reference signal, thereby eliminating the impact of different beam patterns on positioning performance and improving positioning performance.

[0107] Solution 5: The terminal determines the first measurement information of the positioning reference signal of the terminal or reports the first measurement information of the positioning reference signal of the terminal in combination with the beam or beam pattern information of the positioning reference signal.

[0108] In one embodiment, the terminal uses the beam pattern information of the positioning reference signal sending side or the receiving side and the measurement information of the positioning reference signal as input to the AI ​​model.

[0109] In addition to the above solutions 1 to 5, the terminal can also report the measurement information of the positioning reference signal that meets certain conditions or use it as the input of the AI ​​model to constrain the positioning reference signal measured by the terminal to be as consistent as possible with the training data. The measurement information can be determined based on the measurement quantity of one positioning reference signal, and the positioning reference signal that meets certain conditions meets one of the following: the RSRPP of the first path is the largest; the RSRP is the largest; or, the measurement information is determined based on the measurement quantities of N positioning reference signals, or, the specified receiving beam is measured; or, the measurement result of the specified reference signal resource. The positioning reference signal that meets certain conditions is one of the following: N positioning reference signals including the first path, N positioning reference signals with the largest RSRPP of the first path, N positioning reference signals with the largest RSRP, N is a positive integer, and N is greater than or equal to 2.

[0110] Through the above solutions 1 to 5, when the terminal position is different or the terminal is moving, when there are inconsistencies or changes in the beamforming, the AI-based positioning performance can still be guaranteed.

[0111] For downlink positioning, the influence of terminal-side beams can be eliminated. For example, each terminal antenna or port receives positioning reference signals, further eliminating the influence of beam patterns. The network can also instruct the terminal on which reception pattern to use. For terminals in a specific area, the network instructs or recommends which receive beams or angles to use for receiving positioning reference signals, thereby enabling data collection or inference reporting.

[0112] In one embodiment, when the measurement information of the positioning reference signal of the terminal includes intermediate measurement information of the positioning reference signal, the terminal performing the first behavior includes at least one of the following:

[0117] This embodiment may further include the following steps: the terminal combines the AI ​​model to determine the intermediate measurement information of the positioning reference signal of the terminal or the location information of the terminal according to the first measurement information or the second information.

[0137] As shown in FIG7 , specific application of beam or beam pattern information may include the following steps:

[0138] Step 1: The base station reports the transmit beam or beam pattern information to the LMF.

[0139] Step 2: LMF generates a fingerprint database, as shown in the following matrix:
