[0039] It should be noted that the aforementioned wireless communication system may also include a PRU.

[0042] The following description, in conjunction with the accompanying drawings, details the positioning assistance data request, transmission method, apparatus, terminal, network-side device, medium, and computer program products provided in this application through some embodiments and application scenarios.

[0043] The positioning assistance data request, sending method, device, terminal, network-side equipment, medium, and computer program products provided in this application embodiment can be applied to NR positioning scenarios, especially NR positioning scenarios combined with artificial intelligence (AI).

[0044] The aforementioned NR positioning can be performed via the UU port, based on signal measurements between network-side devices and terminals.

[0045] Currently, AI has been widely applied in various fields. AI units can be implemented in various ways, such as neural networks, decision trees, support vector machines, and Bayesian classifiers. Taking neural networks as an example, as shown in Figure 2, Figure 2 is a schematic diagram of a neural network structure. n represents the number of inputs to the neural network, X1, X2, ..., Xn are n inputs, which are processed through the input layer and hidden layer to obtain the output result Y.

[0046] In a neural network, the input is weighted and summed with a bias, then processed by an activation function to obtain the output. Typically, optimization algorithms are used to optimize the parameters of the neural network. An optimization algorithm is a class of algorithms that minimizes or maximizes an objective function (i.e., a loss function). By using optimization algorithms, the value of the loss function can be minimized; the smaller the loss value, the closer the network model is to reality.

[0047] Most common optimization algorithms are based on the error back propagation (BP) algorithm. The basic idea of ​​the BP algorithm is that the learning process consists of two parts: forward propagation of the signal and backward propagation of the error. During forward propagation, the input sample is introduced from the input layer, processed layer by layer by the hidden layers, and then propagated to the output layer. If the actual output of the output layer does not match the expected output, the process transitions to the error back propagation stage. Error back propagation involves propagating the output error back to the input layer layer by layer through the hidden layers, distributing the error to all units in each layer, thus obtaining the error signal of each unit. This error signal serves as the basis for adjusting the weights of each unit. This process of adjusting the weights through forward and backward propagation is cyclical. This continuous adjustment of weights is the learning and training process of the network. This process continues until the error of the network output is reduced to an acceptable level, or until the predetermined number of learning iterations is reached. Common optimization algorithms include gradient descent, stochastic gradient descent (SGD), mini-batch gradient descent, momentum method, Adadelta, root mean square prop (RMSprop), and adaptive momentum estimation (Adam).

[0048] It should be noted that the AI ​​unit in this application embodiment is described using a neural network as an example. In actual implementation, the specific type of AI unit is not limited.

[0049] The positioning assistance data request and sending method provided in this application embodiment allows the terminal to use the requested first positioning assistance data to assist AI positioning. Therefore, through the AI ​​unit, multiple positioning assistance data can be associated to perform positioning, resulting in more accurate positioning data and thus improving the accuracy of terminal positioning.

[0050] The following description, in conjunction with the accompanying drawings, details the positioning assistance data request, transmission method, apparatus, terminal, network-side device, medium, and computer program products provided in this application through some embodiments and application scenarios.

For example, the aforementioned dataset identifier can be used to determine the data format or the auxiliary information associated with the data, so that the network-side device can determine the format or content of some data in the positioning assistance data based on the dataset identifier. It is understood that the positioning assistance data includes the aforementioned first positioning assistance data.

[0074] Understandably, through the aforementioned PRU identifier or dataset identifier, the terminal can request the PRU or dataset that it wishes to use to obtain positioning assistance data in order to accurately perform AI positioning.

[0088] It should be noted that a detailed description of the performance of the terminal monitoring AI unit can be found in the relevant description in step 304 below. To avoid repetition, it will not be repeated here.

[0089] In some embodiments of this application, the above-mentioned acquisition of AI units can be understood as the process by which the terminal trains AI units based on a dataset to obtain trained AI units.

[0090] In some embodiments of this application, the aforementioned first time window information can be used to request a Positioning Reference Signal (PRS) located within the first time window, or to request PRU measurement information within the first time window.

[0091] In some embodiments of this application, the aforementioned first time window information may be determined based on the time of AI monitoring. This allows the terminal to determine whether the AI ​​unit is effective at that time based on the PRU measurement information within the first time window.

[0092] In some embodiments of this application, the aforementioned first request message may include: first time window information and identification information related to the positioning reference signal. It is understood that the first request message is used to request the transmission or measurement of positioning reference information related to the first time window information.

[0093] In some embodiments of this application, the first request message may further include: first time window information and cell information where the terminal is located; or, the first request message may further include: first time window information and area information where the terminal is located. It is understood that the first request message can be used to request location assistance data related to the first time window information within that cell or area.

[0096] In some embodiments of this application, the first request message can be used to indicate that the PRU measurement information is expected to include the positioning reference signal of a specified area or a specified cell; or, the first request message can be used to indicate that the positioning assistance data sent by the network-side device is expected to include the positioning reference signal of a specified area or a specified cell.

[0097] It is understandable that when the first request message indicates that the PRU measurement information is expected to include the location reference signal of a specified area or a specified cell, it means that the terminal expects the received PRU measurement information to include the location reference signal of the specified area or a specified cell. Similarly, when the first request message indicates that the location assistance data sent by the network-side device is expected to include the location reference signal of a specified area or a specified cell, it means that the terminal expects the location assistance data sent by the network-side device to include the location reference signal of the specified area or a specified cell.

[0098] For example, the terminal may add specified area information or specified cell information to the first request message to indicate that the PRU measurement information is expected to include the location reference signal of the specified area or the specified cell, or to indicate that the location assistance data sent by the network-side device is expected to include the location reference signal of the specified area or the specified cell.

[0101] It is understandable that when the first request message indicates that the PRU measurement information is expected to include measurement information associated with a specified positioning reference signal resource set, it can be said that the terminal expects the received PRU measurement information to include measurement information associated with the specified positioning reference signal resource set. Similarly, when the first request message indicates that the positioning assistance data sent by the network-side device is expected to include positioning assistance data associated with a specified positioning reference signal resource set, it can be said that the terminal expects the positioning assistance data sent by the network-side device to include positioning assistance data associated with the specified positioning reference signal resource set.

[0102] For example, the terminal may add specified area information or specified cell information to the first request message to indicate that the PRU measurement information is expected to include measurement information associated with a specified location reference signal resource set, or that the positioning assistance data sent by the network-side device is expected to include positioning assistance data associated with a specified location reference signal resource set.

[0103] In some embodiments of this application, during data acquisition, the network-side device can directly obtain the measurement information of the PRU. For example, the PRU can measure the positioning reference signal, and the terminal can also measure the positioning reference signal. The AI ​​unit is obtained based on the measurement information of the PRU and the terminal and / or the location-related information of the PRU and the terminal. Thus, if the terminal needs to perform positioning through the AI ​​unit, the measurement configuration of the positioning reference signal supported by the terminal needs to be aligned with the measurement configuration during the training period. Therefore, during the AI ​​unit inference process on the terminal side, the network-side device and the terminal can agree on at least one set of configurations. Thus, during the acquisition of positioning auxiliary data, the terminal can report the supported configuration information so that the network-side device can directly configure the terminal with the corresponding configuration, or the terminal can directly report the configuration information it uses to the network-side device.

[0104] Understandably, if the AI ​​unit was trained on data in region A during data acquisition, it may not be able to perform inference when the terminal switches to region B. Therefore, the terminal needs to carry information about region A associated with the AI ​​unit to request location-aided data associated with region A.

[0105] It is understood that during data acquisition, the aforementioned AI unit is associated with the first TRP set. Therefore, if the positioning assistance data does not include the first TRP set, the terminal cannot perform AI positioning based on that positioning assistance data and the AI ​​unit. The terminal needs to request the positioning assistance data that includes the first TRP set. Therefore, the first request message includes indication information related to the first TRP set.

[0106] It is understood that during data acquisition, the aforementioned AI unit is associated with the first positioning reference signal set. Therefore, if the positioning assistance data does not include the first positioning reference signal set, the terminal cannot perform AI positioning based on that positioning assistance data and the AI ​​unit. The terminal needs to request the positioning assistance data that includes the first positioning reference signal set. Therefore, the first request message includes indication information related to the first positioning reference signal set.

[0107] Thus, through the first request message, the terminal can request specified location assistance data from the network-side device, thereby enabling the terminal to perform AI positioning based on the specified location assistance data, thereby improving the accuracy of terminal positioning.

[0108] In some embodiments of this application, the first positioning assistance data may include at least one of the following: measurement information of at least one PRU; location-related information of at least one PRU; cell information associated with the first positioning assistance data; area information associated with the first positioning assistance data; first indication information; auxiliary data for positioning reference signals; auxiliary data required by the terminal to perform location calculation; area ID; cell list ID.

[0109] In some embodiments of this application, the measurement information of the PRU may include at least one of the following: measurement unit information associated with the first path detected by the terminal in the time domain; M first measurement unit information; N second measurement unit information; measurement information type information; and PRU identification information.

That is, the measurement information of the PRU mentioned above includes the measurement information corresponding to the M+1 diameters. The measurement information of the first diameter is indicated separately.

[0116] The measurement information corresponding to the first diameter may differ from the measurement information corresponding to the other diameters among the M diameters mentioned above.

[0117] In some embodiments of this application, the measurement information corresponding to the first diameter is not included in the aforementioned N second measurement unit information. That is, the measurement information of the aforementioned PRU includes N+1 measurement information items. Among them, the measurement information of the first diameter is indicated separately.

[0118] In some embodiments of this application, the first positioning request includes request information related to the measurement information of the PRU, such as type information for requesting the measurement information of the PRU, thereby determining the content of the measurement information of the PRU.

[0127] In some embodiments of this application, the measurement information associated with the multiple TRPs can be of the same type. For example, if the measurement information associated with TRP1 is first measurement unit information, the measurement information associated with TRP2 and TRP3 can also be first measurement unit information.

[0131] In some embodiments of this application, the aforementioned path delay can be the delay information of different transmission paths, such as the TOA of each path.

[0132] In some embodiments of this application, the sampling point delay can be the delay information corresponding to different sampling points. For example, if a signal measurement includes c, the sampling point delay can be the delay information corresponding to N sampling points out of 4096 sampling points.

[0133] Here, M or N can be indicated by the network side or specified by the protocol.

[0134] There are various methods for selecting N sampling points from multiple sampling points, such as determining them based on the power information of different sampling points or based on the time delay information of the first path. This application does not impose specific limitations on these methods in its embodiments.

[0139] In some embodiments of this application, the PRU identification information may include PRU identification information.

[0140] In some embodiments of this application, the location-related information of the PRU mentioned above may include at least one of the following: absolute location information of the PRU; relative location information of the PRU; second time information; and first phase information.

[0141] In some embodiments of this application, the absolute location information of the terminal may include the terminal's absolute longitude and absolute latitude information.

[0142] In some embodiments of this application, the relative position information of the terminal can be the position information of the terminal relative to a reference position.

[0143] In some embodiments of this application, the second time information may include arrival time information between the PRU and at least one TRP, or the second time information may include arrival time difference information between the PRU and at least one TRP pair.

[0144] In some embodiments of this application, the arrival time information is calculated based on the location information of the terminal and the location information of at least one TRP, and the arrival time difference information is calculated based on the location information of the terminal and the location information of at least one TRP pair.

[0150] In some embodiments of this application, the second time information may include arrival time information between the PRU and at least one TRP, or the second time information may include arrival time difference information between the final PRU and at least one TRP pair.

[0151] In some embodiments of this application, the arrival time information is calculated based on the location information of the PRU and the location information of at least one TRP, and the arrival time difference information is calculated based on the location information of the PRU and the location information of at least one TRP pair.

[0152] In some embodiments of this application, the second time information may include at least one of the following: arrival time of transmission between the PRU and at least one TRP; reference signal time difference (RSTD) information between the PRU and at least one TRP pair; and receive Rx-transmit Tx time difference information between the PRU and at least one TRP.

[0153] In some embodiments of this application, the first phase information includes arrival phase information between the PRU and at least one TRP, or the first phase information includes arrival phase difference information between the PRU and at least one TRP pair.

[0154] In some embodiments of this application, the first request carries indication information to indicate that the location-related information of the PRU specifically includes one or more of the absolute location information of the PRU, the relative location information of the PRU, the second time information, and the first phase information.

[0155] In some embodiments of this application, the cell information associated with the first positioning assistance data may include, but is not limited to: NCGI information, cell ID information, and TRP ID information.

[0156] Understandably, the cell information associated with the first positioning assistance data includes the cell information in the first request message. Therefore, if the cell information associated with the first positioning assistance data does not include the cell information in the first request message, then the first positioning assistance data indicates that it cannot respond to the first request message.

[0157] In some embodiments of this application, the area information associated with the first positioning assistance data may include information about the area where the first positioning assistance data is obtained.

[0158] For example, the area information associated with the first positioning assistance data can be an area ID.

[0159] Understandably, the area information associated with the aforementioned first positioning assistance data includes the area information in the first request message. Therefore, if the area information associated with the first positioning assistance data cannot include the area information in the first request, then the first positioning assistance data indicates that it cannot respond to the first request.

[0160] In some embodiments of this application, the first indication information described above can be used to indicate at least one of the following: the data indicated by the dataset identifier has changed, the area associated with the first positioning assistance data has changed, the cell associated with the first positioning assistance data has changed, the TRP environment associated with the first positioning assistance data has changed, the PRU in the first positioning assistance data has changed, and the positioning reference signal in the first positioning assistance data has changed.

[0161] It is understood that the first indication information indicating a change in at least one of the above can be interpreted as: a change in the data indicated by the dataset identifier, the area associated with the first positioning assistance data, the cell associated with the first positioning assistance data, the TRP associated with the first positioning assistance data, the PRU in the first positioning assistance data, or the positioning reference signal in the first positioning assistance data relative to the transmission of the first positioning assistance data. In other words, at least one of the above has changed relative to the current positioning assistance data transmission.

[0162] In some embodiments of this application, the first indication information may include at least one of the following: PRU update indication information; TRP update indication information; dataset update indication information; positioning reference signal update indication information.

[0163] It is understood that the aforementioned first indication information can indicate each TRP, each PRS resource set, or each PRS resource in the first positioning assistance information, specifically indicating which TRP, PRS resource set, or PRS resource has changed.

[0164] It is understood that the area information associated with the aforementioned first positioning assistance data can include the area information in the first request message. However, if some information in the specific information associated with the first positioning assistance data changes, the network-side device needs to notify the terminal that the corresponding information has changed. For example, if the first positioning assistance data is still associated with area A, but cell 1 under area A has changed, the network-side device needs to indicate that cell 1 has changed. As another example, if the first positioning assistance data is still associated with area A, but the positioning reference signal of cell 1 under area A has changed, the first positioning assistance data can indicate that the positioning reference signal has changed.

[0165] In some embodiments of this application, after the terminal receives the first positioning assistance data, if the data indicated by the dataset identifier changes, the area associated with the first positioning assistance data changes, the cell associated with the first positioning assistance data changes, the TRP environment associated with the first positioning assistance data changes, the PRU in the first positioning assistance data changes, or the positioning reference signal in the first positioning assistance data changes, the terminal may request updated PRU data or dataset from the network-side device. Alternatively, the network-side device may directly carry at least one of the above-mentioned update indication information in the first indication information, so that the terminal can accurately locate itself by combining the latest positioning assistance data.

[0166] In some embodiments of this application, the aforementioned region ID can be the region ID of the region where the terminal is located.

[0167] In some embodiments of this application, the aforementioned cell list ID can be the cell list ID associated with the cell where the terminal is located.

[0168] In some embodiments of this application, the first positioning assistance data may further include at least one of the following: the location information of the TRP, and the beam-related information of the TRP.

[0169] It is understandable that, typically, only UE-based positioning can obtain the TRP's location information and beam-related information; while in UE-assisted positioning, since positioning is performed by network-side devices, this information is not needed. However, in the positioning assistance data request method provided in this application embodiment, even for UE-assisted AI positioning, it is necessary to combine the TRP's location information and / or the TRP's beam-related information to assist the terminal in performing AI positioning, such as monitoring the performance of the AI ​​unit. Therefore, the aforementioned first positioning assistance data may further include at least one of the TRP's location information and the TRP's beam-related information.

[0170] In this way, the terminal can combine at least one of the TRP's location information and beam-related information to more accurately monitor the performance of the AI ​​unit.

[0171] The positioning assistance data request method provided in this application embodiment allows the terminal to use the requested first positioning assistance data to assist AI positioning. Therefore, through the AI ​​unit, multiple positioning assistance data can be associated to perform positioning, resulting in more accurate positioning data and thus improving the accuracy of terminal positioning.

[0172] In some embodiments of this application, the positioning assistance data request method provided in this application may further include the following step 303.

[0173] Step 303: Based on the first positioning assistance data and the AI ​​unit, the terminal locates itself and outputs the terminal's location-related information.

[0174] In some embodiments of this application, after receiving first positioning assistance data sent by a network-side device, the terminal can determine its measurement information based on the first positioning assistance data, and input the terminal's measurement information into an AI unit to obtain estimated location-related information of the terminal. The estimated location-related information of the terminal includes at least one of the following: estimated absolute location information of the terminal; estimated relative location information of the terminal; estimated arrival time information between the terminal and at least one TRP; and estimated arrival time difference information between the terminal and at least one TRP pair.

[0175] In some embodiments of this application, the AI ​​unit described above can be an AI unit trained by a network-side device. The terminal can receive configuration information of the AI ​​unit sent by the network-side device, and obtain the AI ​​unit based on the configuration information.

[0176] In some embodiments of this application, the location-related information of the terminal may include at least one of the following: absolute location information of the terminal; relative location information of the terminal; third time information; and second phase information.

[0177] In some embodiments of this application, the aforementioned third time information may include arrival time information between the terminal and at least one TRP, or the third time information may include arrival time difference information between the terminal and at least one TRP pair.

[0178] In some embodiments of this application, the second phase information may include arrival phase information between the terminal and at least one TRP, or the second phase information may include arrival phase difference information between the terminal and at least one TRP pair.

[0179] It should be noted that for a detailed description of the location-related information of the aforementioned terminals, please refer to the above description of the location-related information of the PRU. To avoid repetition, it will not be repeated here.

[0180] In some embodiments of this application, each AI unit has its applicable area, time, scene, or measurement type. Therefore, the first positioning assistance data needs to be adapted to the applicable conditions of the AI ​​unit being used. In this way, through the AI ​​unit and the first positioning assistance data adapted to that AI unit, more accurate terminal location information can be obtained, improving the terminal positioning accuracy.

[0181] In some embodiments of this application, after receiving the first positioning assistance data sent by the network-side device, the terminal can input the first positioning assistance data into the AI ​​unit to monitor the AI ​​unit.

[0182] In some embodiments of this application, where the first positioning assistance data includes: measurement information of at least one PRU and location-related information of at least one PRU, the positioning assistance data request method provided in this application embodiment may further include the following step 304.

[0183] Step 304: The terminal monitors the AI ​​unit based on the measurement information of at least one PRU and the location-related information of at least one PRU to obtain the monitoring information of the AI ​​unit, which is used to indicate the performance of the AI ​​unit.

[0184] In some embodiments of this application, the monitoring information of the AI ​​unit may be the validity information of the AI ​​unit or the KPI information related to the AI ​​unit. Optionally, the monitoring information of the AI ​​unit may be obtained based on the difference information between the location-related information of at least one PRU of the AI ​​unit and the estimated location-related information of at least one PRU.

[0185] In some embodiments of this application, the monitoring information of the AI ​​unit may be the validity information of the AI ​​unit or the key performance indicator (KPI) information related to the AI ​​unit.

[0186] In some embodiments of this application, the monitoring information of the AI ​​unit can be obtained based on the difference information between the location-related information of at least one PRU of the AI ​​unit and the estimated location-related information of at least one PRU.

[0187] Understandably, the smaller the difference between the location-related information of at least one PRU and the estimated location-related information of at least one PRU, the higher the accuracy of the AI ​​unit's predictions and the better its performance. Conversely, the larger the difference between the location-related information of at least one PRU and the estimated location-related information of at least one PRU, the lower the accuracy of the AI ​​unit's predictions and the worse its performance.

[0188] In some embodiments of this application, step 304 may include step 304a as described below.

[0189] Step 304a: Based on the measurement information of at least one PRU and the AI ​​unit, the terminal estimates the estimated location-related information of at least one PRU, and compares the location-related information of at least one PRU with the estimated location-related information of at least one PRU to obtain the monitoring information of the AI ​​unit.

[0190] In some embodiments of this application, the terminal can input measurement information of at least one PRU into the AI ​​unit to estimate the estimated location-related information of at least one PRU. Then, the location-related information of the at least one PRU and the estimated location-related information of the at least one PRU are compared to obtain the monitoring information of the AI ​​unit.

[0191] In this way, by monitoring the performance of the AI ​​unit, adjustments can be made in a timely manner when the performance of the AI ​​unit deteriorates, such as replacing the AI ​​unit or retraining the AI ​​unit to maintain its performance.

[0192] It should be noted that, by comparing cases 303 and 304, it can be found that the PRU's measurement information replaces the terminal's measurement information, but the same AI unit is used. Therefore, the PRU's measurement information should be consistent with the terminal's measurement information in order to determine whether the AI ​​unit can be used to determine the terminal's location-related information.

[0193] Understandably, the distance between the location of the PRU and the location of the terminal should not be too far; for example, the PRU and the terminal can be located in the same area.

[0194] It is understandable that the TRP set associated with the PRU's measurement information should not differ too much from the TRP set associated with the terminal's measurement information. For example, the TRP set associated with the PRU's measurement information can be consistent with or partially consistent with the TRP set associated with the terminal's measurement information.

[0195] In some embodiments of this application, the first request message may further include at least one of the following: identification information of the positioning reference signal; associated ID information of the network-side device; measurement indication information of the terminal; type of positioning auxiliary data; second request message; pre-configured positioning auxiliary data request; periodic dataset request; periodic positioning auxiliary data request; positioning auxiliary information and dataset update indication request; frequency point that the terminal expects to measure; frequency layer that the terminal expects to measure; bandwidth that the terminal expects to measure; sampling point granularity that the terminal expects; number of sampling points that the terminal expects; type of measurement information that the terminal expects.

[0196] In some embodiments of this application, the identification information of the positioning reference signal may include at least one of the following: frequency layer information of the positioning reference signal; identification information of the TRP transmitting the positioning reference signal; resource set ID of the positioning reference signal; resource ID of the positioning reference signal.

[0197] The first request message mentioned above includes frequency layer information of the positioning reference signal, which can be used to indicate the frequency layer that the terminal expects to measure.

[0198] The first request message mentioned above includes bandwidth information of the positioning reference signal, which can be used to indicate the bandwidth information that the terminal expects to measure.

[0199] In some embodiments of this application, the terminal may perform a measurement of the indicated positioning reference signal within a first time window and send the obtained identification information of the indicated positioning reference signal to the network-side device in a first request message. Therefore, the first request message may include the first time window information and the identification information of the positioning reference signal.

[0200] In some embodiments of this application, the identification information of the TRP may include at least one of the following: the cell ID associated with the TRP, GCI.

[0201] In some embodiments of this application, the terminal can perform the measurement of the indicated TRP within a first time window and send the obtained identification information of the indicated TRP to the network-side device in a first request message. Therefore, the first request message may include the first time window information and the TRP identification information.

[0202] In some embodiments of this application, the first request message may include identification information of the positioning reference signal and first time window information. The first request information may be used to request the positioning assistance data sent by the network-side device to include the specified positioning reference signal located within the first time window. The first time window may be the time window indicated by the first time window information.

[0203] In some embodiments of this application, the same related ID information may indicate that at least one of the following configurations is the same: configuration information of the positioning reference signal, dataset information, beam configuration information, TRP configuration information, and positioning assistance information.

[0204] It is understandable that if an AI unit is associated with relevant ID information, the terminal expects the relevant ID information during the AI ​​unit's inference phase to be consistent with the relevant ID information associated with the AI ​​unit, wherein the same relevant ID information should indicate the same information. Therefore, the aforementioned first request information may include relevant ID information in order to expect the positioning assistance data to include positioning assistance data associated with the relevant ID information.

[0205] In other words, the first request message can be used to instruct network-side devices or terminals to obtain the relevant ID information of the network-side devices associated with the AI ​​unit when performing AI unit inference, training, and monitoring. This ensures that the relevant ID information of the network-side devices is consistent with the desired training and inference phases.

[0206] In some embodiments of this application, the aforementioned related ID information may be associated with at least one of the following: cell ID; cell list ID; area ID; TRP ID; configuration information for on-demand request for location reference signal.

[0207] In some embodiments of this application, the aforementioned related ID information can be used to identify at least one of the following under cell ID, cell list ID, area ID, or TRP ID: configuration information of positioning reference signals; dataset information for AI positioning; beam configuration information; positioning assistance information; and identification information of on-demand positioning reference signals.

[0208] It is understood that, when the relevant ID information is associated with the configuration information of the on-demand location reference signal, the same relevant ID information in AI unit training and inference can indicate at least one of the following: the configuration information of the same on-demand location reference signal in the location assistance data, and the identification information of the same on-demand location reference signal.

[0209] In some embodiments of this application, the aforementioned related ID information is associated with the cell ID. Under the same cell ID, the same related ID information indicates that at least one of the following configurations is the same: the configuration information of the positioning reference signal, the dataset information, the beam configuration information, the TRP configuration information, and the positioning assistance information.

[0210] It is understandable that, when related ID information is associated with cell ID, under the same cell ID, the same related ID information can indicate that at least one of the following is the same: the configuration information of the positioning reference signal, the dataset information, the beam configuration information, the TRP configuration information, and the positioning assistance information.

[0211] In some embodiments of this application, the aforementioned related ID information is associated with the TRP ID, and the same related ID information indicates at least one of the following: the same TRP ID in the positioning assistance data, the same TRP location, and the same positioning reference signal configuration information.

[0212] In some embodiments of this application, the aforementioned related ID information is associated with a cell list ID, and the same related ID information indicates at least one of the following: the same cell list ID in the location assistance data, and the same TRP set.

[0213] In some embodiments of this application, the aforementioned related ID information is associated with a region ID, and the same related ID information indicates at least one of the following: the same region ID in the location assistance data, and the same TRP set.

[0214] In some embodiments of this application, the aforementioned related ID information is associated with the configuration information of the on-demand request positioning reference signal, and the same related ID information indicates at least one of the following: the configuration information of the same on-demand request positioning reference signal in the positioning assistance data, and the identification information of the same on-demand request positioning reference signal.

[0215] In some embodiments of this application, the configuration information of the on-demand request positioning reference signal can be pre-configured, and the relevant ID information can correspond to the pre-configured configuration information of the on-demand request positioning reference signal.

[0216] In some embodiments of this application, the aforementioned related ID information is also used to identify target positioning assistance information from K groups of positioning assistance information under cell ID, cell list ID, area ID or TRP ID, where K is a positive integer.

[0217] In some embodiments of this application, the first request message may include cell information and related ID information.

[0218] In some embodiments of this application, the first request message may also include region information and related ID information.

[0219] In some embodiments of this application, the first request message may also include region information, related ID information, and first time information.

[0220] In some embodiments of this application, the first request message may also include region information, related ID information, and first time window information.

[0221] In some embodiments of this application, the auxiliary data for the positioning reference signal sent by the network-side device may include auxiliary data for multiple sets of positioning reference signals. Auxiliary data for different sets of positioning reference signals may be associated with different IDs. Thus, the terminal can identify the target positioning auxiliary information from K sets of positioning auxiliary information based on the relevant ID information, under the cell ID, cell list ID, area ID, or TRP ID.

[0222] In some embodiments of this application, the above-mentioned measurement indication information can be used to indicate at least one of the measurement method and the type of measurement quantity used by the terminal, so that the measurement information of the PRU issued by the network-side device corresponds to the measurement indication information in the first request message.

[0239] Among them, the above-mentioned at least one PRU is the PRU that the terminal expects to use to obtain positioning assistance data among multiple PRUs associated with the network-side device.

[0245] The positioning assistance data transmission method provided in this application embodiment allows the terminal to use the requested first positioning assistance data to assist AI positioning. Therefore, through the AI ​​unit, multiple positioning assistance data can be associated to perform positioning, resulting in more accurate positioning data and thus improving the accuracy of terminal positioning.

[0249] Step 503: The network-side device sends the first positioning assistance data to the terminal.

[0250] Step 504: The terminal obtains the first positioning assistance data from the network-side device.

Therefore, through the AI ​​unit, multiple positioning assistance data can be associated to perform positioning, resulting in more accurate positioning data and thus improving the accuracy of terminal positioning.

[0256] Step 602: The network-side device receives the first request message and obtains the PRU measurement information corresponding to the first time information and the first time window.

[0257] The PRU measurement request information includes first-time information and first-time window information.

[0258] Step 603: The network-side device sends the first time information and the PRU measurement information corresponding to the first time window.

[0260] Step 605: The terminal performs AI-based positioning to obtain at least one of the terminal's measurement information and location information, or the terminal performs AI-based monitoring.
