[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202411577541.0, filed on November 6, 2024, entitled "Location Data Transmission Method, Apparatus, Terminal, Network Side Device and Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of communication technology, specifically relating to a positioning data transmission method, device, terminal, network-side equipment, and storage medium. Background Technology

[0004] In wireless communication signal-based positioning, network-side devices can provide auxiliary data for downlink positioning based on the current environment of the terminal. After obtaining the auxiliary data provided by the network-side devices, the terminal measures the downlink positioning reference signal based on the auxiliary data and obtains measurement data or location estimation data.

[0005] With the rapid development of artificial intelligence (AI) technology, research on AI use cases in the field of communications is gradually increasing, such as AI-based positioning. AI-based positioning mainly relies on AI units to obtain reliable location predictions or predictions of intermediate measurements related to positioning.

[0006] To ensure good inference performance from the AI ​​unit—that is, to make the prediction information obtained through the AI ​​unit more reliable—the terminal needs to guarantee good consistency between the input datasets used for AI unit training and inference. Specifically, the auxiliary data obtained during AI unit training should be consistent with the auxiliary data used during AI unit inference. However, due to the mobility of the terminal and the variability of network deployment, the terminal cannot determine the correlation between the dataset obtained during inference and the dataset used for training. This reduces the effectiveness of the dataset and lowers the performance of AI unit inference. Summary of the Invention

[0049] To facilitate understanding, the relevant technologies and concepts involved in the embodiments of this application will be introduced first.

[0050] I. AI / Machine Learning (ML)

[0051] AI units can be implemented in various ways, such as neural networks, decision trees, support vector machines, and Bayesian classifiers.

[0052] In the embodiments of this application, the AI ​​unit may also be referred to as an AI model, AI module, ML model, ML unit, ML module, AI structure, AI function, AI characteristic, neural network, neural network function, neural network feature, etc. Alternatively, the AI ​​unit may refer to a processing unit or processing module that can implement specific algorithms, formulas, processing flows, capabilities, etc. related to AI. Alternatively, the AI ​​unit may be a processing method, algorithm, function, characteristic, module, or unit for a specific dataset. Alternatively, the AI ​​unit may be a processing method, algorithm, function, characteristic, module, or unit running on AI / ML related hardware such as a graphics processing unit (GPU), neural processing unit (NPU), tensor processing unit (TPU), or application-specific integrated circuit (ASIC). The embodiments of this application do not specifically limit this.

[0053] Optionally, the aforementioned specific dataset may include the input and / or output of the AI ​​unit. Optionally, the identifier of the aforementioned AI unit may be an AI model identifier, an AI structure identifier, an AI algorithm identifier, or an identifier of a specific dataset associated with the AI ​​unit, or an identifier of a specific scenario, environment, channel characteristics, or device related to AI / ML, or an identifier of a function, feature, capability, or module related to AI / ML. This application embodiment does not specifically limit this.

[0054] AI-based localization relies primarily on AI models to obtain reliable location predictions or intermediate measurement predictions regarding localization. To achieve reliable output, training these AI models requires a large amount of input, including historical measurement data, location data, and known label data.

[0055] Data sets used for model training in AI localization can include:

[0056] Channel measurement, quality metrics of channel measurement, timestamps of channel measurement;

[0057] The quality indicators of the actual tag (i.e., the actual location of the terminal or power receiving unit (PRU), or an approximation thereof), and the timestamp of the tag.

[0058] For downlink positioning, the terminal needs to measure the downlink (DL) positioning reference signal (PRS) (DL-PRS) to obtain measurement data. Therefore, the data used for AI unit / AI model training and inference needs to be based on a certain DL-PRS configuration, which can come from:

[0059] 1) UE Initiated

[0060] The terminal can proactively request a preferred DL-PRS configuration from the Location Management Function (LMF) for training data collection, such as on-demand PRS. Upon receiving the terminal's request, the LMF is responsible for determining the final DL-PRS configuration to meet the terminal's training data collection needs and providing auxiliary data to the terminal.

[0061] 2) LMF Initiated

[0062] LMF independently determines the DL-PRS configuration for training data collection and provides auxiliary data to the terminal without requiring a request from the terminal.

[0063] II. Data Consistency

[0064] Data consistency is crucial for algorithm and model performance. If the training and test datasets differ significantly, a model trained on the training dataset will struggle to achieve good performance on the test dataset. Ideally, the training, test, and actual processing data should have good consistency; under this condition, the trained model will perform well. However, in real-world dataset construction, various practical constraints mean that the training and test datasets may not perfectly match the data processed in the actual scenario, potentially leading to decreased inference performance.

[0065] III. NR Positioning

[0066] NR positioning is a technology that uses NR reference signals to measure and estimate the terminal's location, or further calculates the location based on the measurements, between the terminal and network-side equipment. It supports one-shot, periodic, and location event-triggered positioning processes. The relevant positioning technology is primarily aimed at connected terminals, but it can also support positioning of inactive and idle terminals. Specifically, RRC_INACTIVE / IDLE UEs can perform measurements in the disconnected state and report them after entering the connected state.

[0067] The LTE Positioning Protocol (LPP) is the protocol used by the terminal and the Local Positioning Filter (LMF) to exchange location-related information. LPP supports location-related transactions such as terminal positioning capability exchange, auxiliary data transmission, and location information transmission between the terminal and the LMF. The LPP process does not require any fixed order to occur, thus providing greater positioning flexibility.

[0068] IV. Positioning-Assisted Data Interaction

[0069] Terminals can request auxiliary data from the LMF (Local Support Provider) for positioning via the LPP (Local Support Protocol) Request Assisted Data Message; the LMF can also directly send auxiliary data to the terminal via the LPP Assisted Data Message. Furthermore, the auxiliary data interactions supported by the relevant LPP protocols organize the auxiliary data according to the positioning method.

[0070] V. PRS as needed

[0071] The on-demand PRS transmission process allows the LMF to control and decide whether to transmit PRS and to modify the characteristics of an ongoing PRS transmission. The on-demand PRS transmission process can be initiated by the terminal (e.g., the terminal requests pre-configured PRS transmission characteristics from the LMF) or by the LMF. Regardless of whether the process is initiated by the terminal or the LMF, the actual PRS changes are requested by the LMF from the base station.

[0072] As shown in Figure 2, the specific process is as follows:

[0073] 0. During the information exchange at the Transmit-Receive Point (TRP), the LMF receives information about the possible PRS configurations that the gNB can support, and can interact based on NR positioning protocol A (NRPPa).

[0074] 1. LMF can provide auxiliary data messages via LPP or pre-configured PRS via Positioning System Information (posSI);

[0075] 2a. When the terminal initiates on-demand PRS, the terminal sends an on-demand PRS request to the LMF via an LPP request auxiliary data message. The on-demand PRS request may be a request for a predefined PRS configuration indicated by a predefined PRS configuration identifier or explicit parameters used for PRS configuration, and may be a request for changes to PRS transmission or for PRS transmission characteristics used for positioning measurements.

[0076] It is important to note that if the NW has already provided the terminal with a predefined on-demand PRS configuration, the terminal is allowed to request on-demand PRS parameters within the range of the received predefined on-demand PRS configuration based on the predefined on-demand PRS configuration ID (index-based request) or by explicitly requesting parameters. Otherwise, the terminal can blindly request on-demand PRS parameters within the allowed parameter list by explicitly requesting them.

[0077] 2b. When the LMF initiates on-demand PRS, the LMF and the terminal exchange LPP messages to obtain the terminal's measurement results or the terminal's ability to receive PRS positioning, etc.

[0078] 3. LMF determines whether PRS transmission is needed or whether the transmission characteristics of an ongoing PRS transmission need to be changed;

[0079] 4. LMF requests new PRS transports or PRS transports that change PRS configurations from serving and non-serving gNB / TRPs via NRPPa-based PRS configuration request messages.

[0080] 5.gNB / TRP correspondingly provides a successful configuration or update PRS transport in the NRPPa-based PRS configuration response message;

[0081] 6. The LMF provides PRS configuration to the terminal via auxiliary data messages through the LPP.

[0082] The relevant technologies and concepts involved in the embodiments of this application have been introduced above. In the relevant technologies, the positioning process is mainly used to obtain positioning results in real time. Therefore, the current auxiliary information may not include the globally unique identifier information of the cell, but only provide logical physical cell identifier information, which is used by the terminal to identify / determine the network-side configuration related to this positioning process. In addition, for the relevant on-demand PRS process, the terminal does not need to pay attention to the specific participating cell in this positioning, so the request does not include the globally unique identifier information of the cell where the terminal is camped.

[0083] However, for AI localization, the training and inference processes are not correlated in time, and the network configuration and corresponding auxiliary information may change. If the network configuration during inference and training are inconsistent, it may affect the performance of the AI ​​unit or render the AI ​​unit unusable.

[0084] The following description, in conjunction with the accompanying drawings, details a positioning data transmission method provided by the embodiments of this application through some examples and application scenarios.

[0085] Referring to Figure 3, which is a flowchart of an implementation of a positioning data transmission method provided in this application, the method includes the following steps:

[0086] S310: The terminal sends a first message to the first network-side device, wherein the first message is used to request the first network-side device to provide first auxiliary data, the first message carries first information, and the first information is used to indicate the tendency of the terminal to request the first auxiliary data;

[0087] S320: The terminal receives a second message from the first network-side device, wherein the second message is used to provide the terminal with second auxiliary data;

[0088] S330: The terminal measures the downlink positioning reference signal and acquires the dataset based on the second message.

[0089] Using the method provided in the embodiments of this application, the terminal sends a first message to a first network-side device. The first message requests the first network-side device to provide first auxiliary data. The first message carries first information, which indicates the terminal's preference for the first auxiliary data requested. That is, when the terminal requests the first network-side device to provide the first auxiliary data, it also informs the first network-side device of the first auxiliary data it prefers to obtain. This allows the first network-side device to provide the terminal with second auxiliary data based on the terminal's preference for the first auxiliary data requested. As a result, the terminal can obtain a dataset suitable for the current AI unit during AI unit training, or the dataset obtained by the terminal during AI unit inference or supervision is correlated with the dataset used for training, which helps to improve the effectiveness of the dataset and enhance the performance of AI unit inference.

[0090] In this embodiment of the application, the terminal can be terminal 11 in FIG1, and the first network-side device can be LMF.

[0091] The terminal may send a first message to a first network-side device. This first message requests the first network-side device to provide first auxiliary data. The first message may carry first information indicating the terminal's preference for the requested first auxiliary data. Optionally, the first message may include an LPP request for auxiliary data message.

[0092] Optionally, the terminal may send a first message to the first network-side device based on the terminal's current location, network conditions, or other relevant factors.

[0093] The first network-side device receives a first message from the terminal and sends a second message to the terminal. This second message is used to provide the terminal with second auxiliary data. Optionally, the second message may carry second information indicating the applicability of the second auxiliary data. Optionally, the second message may include an LPP (Local Protocol Power) message providing auxiliary data.

[0094] Optionally, after receiving the first message from the terminal, the first network-side device may consider factors such as network deployment, terminal distribution, and expected positioning accuracy requirements, and send a second message to the terminal to provide second auxiliary data, so that the terminal can measure the downlink positioning reference signal and obtain the dataset based on the second message.

[0095] Optionally, after receiving the first message from the terminal, the first network-side device may consider the terminal's preference for the first auxiliary data, as well as factors such as network deployment, terminal distribution, and expected positioning accuracy requirements, and send a second message to the terminal to provide second auxiliary data, so that the terminal can measure the downlink positioning reference signal and obtain the dataset based on the second message.

[0096] If the first network-side device provides second auxiliary data based on the tendency of the terminal's request for the first auxiliary data, the second auxiliary data will be more closely matched with the tendency of the terminal's request for the first auxiliary data, and the applicability of the second auxiliary data will be better.

[0097] For example, during the AI ​​unit training phase, the terminal measures downlink positioning reference signals and obtains dataset A based on auxiliary data A acquired from the first network-side device. AI unit training is then performed based on dataset A. During the AI ​​unit inference phase, the terminal sends a first message to the first network-side device based on the globally unique cell identifier associated with auxiliary data A, and receives a second message from the first network-side device to obtain auxiliary data B. Downlink positioning reference signals are measured based on auxiliary data B, and dataset B is obtained again. AI unit inference is then performed based on dataset B. If the globally unique cell identifier associated with auxiliary data B is related to the globally unique cell identifier associated with auxiliary data A, the consistency of the cell between the model training and model inference phases can be guaranteed, which helps improve AI unit performance and availability.

[0098] Auxiliary data can be associated with one or more globally unique cell identifiers. The globally unique cell identifier associated with auxiliary data B is related to the globally unique cell identifier associated with auxiliary data A. This can be understood as the globally unique cell identifier associated with auxiliary data B being included in the globally unique cell identifier associated with auxiliary data A, or the globally unique cell identifier associated with auxiliary data B being the same as the globally unique cell identifier associated with auxiliary data A.

[0099] The terminal receives the second message from the first network-side device and can measure the downlink positioning reference signal and obtain the dataset based on the second message.

[0100] Optionally, the dataset can be used for AI unit training, AI unit inference, or AI unit supervision.

[0101] When the terminal requests the first auxiliary data from the first network-side device, it also informs the first network-side device of the first auxiliary data that the terminal prefers to obtain. This allows the first network-side device to determine the second auxiliary data based on the terminal's preference for the first auxiliary data and provide the second auxiliary data to the terminal. This enables the terminal to obtain a dataset suitable for the current AI unit during AI unit training, or to ensure that the dataset obtained by the terminal during AI unit inference or supervision is related to the dataset used for training. This helps to improve the effectiveness of the dataset and enhance the performance of AI unit inference.

[0102] In some embodiments of this application, the first auxiliary data or the second auxiliary data may include at least one of the following:

[0103] On-demand positioning reference signals;

[0104] Location calculation auxiliary information;

[0105] Positioning reference signal configuration information.

[0106] The terminal requests first auxiliary data from a first network-side device. This data could be a request for on-demand positioning reference signals, a request for positioning calculation assistance information, or a request for positioning reference signal configuration information. If the first auxiliary data includes on-demand positioning reference signals, the first information indicates the preference for the on-demand positioning reference signals requested by the terminal. If the first auxiliary data includes positioning calculation assistance information, the first information indicates the preference for the positioning calculation assistance information requested by the terminal. If the first auxiliary data includes positioning reference signal configuration information, the first information indicates the preference for the positioning reference signal configuration information requested by the terminal.

[0107] The first network-side device provides second auxiliary data to the terminal. This data may include on-demand positioning reference signals, positioning calculation assistance information, or positioning reference signal configuration information. If the second auxiliary data includes on-demand positioning reference signals, the second information indicates the applicability of the on-demand positioning reference signals. If the second auxiliary data includes positioning calculation assistance information, the second information indicates the applicability of the positioning calculation assistance information. If the second auxiliary data includes positioning reference signal configuration information, the second information indicates the applicability of the positioning reference signal configuration information.

[0108] In some embodiments of this application, the first information may include at least one of the following:

[0109] The area range of the first auxiliary data;

[0110] AI unit association identifier for the first auxiliary data;

[0111] The first auxiliary data is used for AI unit training;

[0112] The first set of auxiliary data is used for AI unit inference;

[0113] The first set of auxiliary data is used for AI unit supervision.

[0114] In this embodiment, the terminal sends a first message to the first network-side device, requesting the first network-side device to provide first auxiliary data. The first message carries first information to indicate the preference of the terminal in requesting the first auxiliary data.

[0115] The first information may include the regional range of the first auxiliary data, which can be characterized by a globally unique cell identifier. This can be understood as the terminal preferring to request auxiliary data associated with which globally unique cell identifiers from the first network-side device, or the terminal preferring that the auxiliary data provided by the first network-side device is valid under which globally unique cell identifiers. The globally unique cell identifier may include at least one of the following: NR Cell Global Identifier (NCGI), Physical Cell Identifier (PCI), and Absolute Radio Frequency Channel Number (ARFCN).

[0138] The first information can be associated with the auxiliary data requested in the positioning method. Optionally, the first information can be carried in the auxiliary data requested by the positioning method included in the first message (e.g., auxiliary data requested by the positioning method based on NR downlink time difference of arrival (TDOA) (NR-DL-TDOA-RequestAssistanceData-r16)). It can be understood that the effective scope of the first information corresponds to all auxiliary data requested by the positioning method.

[0150] In some embodiments of this application, when the first information is associated with the on-demand positioning reference signal requested in the positioning method, the method may further include the following steps before the terminal sends the first message to the first network-side device:

[0151] The terminal receives a third message from the first network-side device. The third message is used to provide the terminal with pre-configured on-demand positioning reference signal configuration information. The third message carries third information, which is used to indicate the applicability of the pre-configured on-demand positioning reference signal configuration information.

[0152] In this embodiment, before the terminal sends a first message to the first network-side device, or before the first network-side device receives the first message from the terminal, the first network-side device may send a third message to the terminal. This third message is used to provide the terminal with pre-configured on-demand positioning reference signal configuration information. The pre-configured on-demand positioning reference signal configuration information can be understood as on-demand positioning reference signal configuration information recommended by the first network-side device, such as NR-On-Demand-DL-PRS-Configurations.

This can be understood as the applicable area of ​​the pre-configured on-demand positioning reference signal configuration information, such as which globally unique cell identifiers it is associated with, or which AI units the pre-configured on-demand positioning reference signal configuration information applies to. This third information clarifies the applicability of the pre-configured on-demand positioning reference signal configuration information to the terminal.

[0155] Optionally, the third information may be associated with a downlink positioning reference signal identifier (DL-PRS-ID) that identifies the pre-configured on-demand positioning reference signal configuration information.

[0156] The terminal can determine the tendency of the first auxiliary data to be requested based on the third message, and send the first message to the first network-side device, so that the first information carried in the first message is associated with the on-demand positioning reference signal requested in the positioning method.

[0157] Optionally, the first information may include the entire set or a subset of the third information.

[0158] The first network-side device provides the terminal with pre-configured on-demand positioning reference signal configuration information and indicates the applicability of the pre-configured on-demand positioning reference signal configuration information, so that the terminal can determine the appropriate first information according to the instructions of the first network-side device.

[0159] In some embodiments of this application, the method may further include the following steps:

[0160] The terminal sends the dataset to the over-the-top server or the first network-side device serving the terminal.

[0161] In this embodiment of the application, after the terminal receives the second message from the first network-side device, it can measure the downlink positioning reference signal and obtain a dataset based on the second message.

[0162] The terminal can perform AI unit training, AI unit inference, or AI unit supervision based on the dataset.

[0163] Alternatively, the terminal can send the dataset to an Over-The-Top (OTT) server or a first network-side device serving the terminal, where the OTT server or the first network-side device can perform AI unit training, AI unit inference, or AI unit supervision. This helps save terminal resources and improve processing efficiency.

[0164] In some embodiments of this application, before the first network-side device sends the second message to the terminal, the method may further include the following steps:

[0165] The first network-side device determines the second network-side device based on the first message.

[0166] In this embodiment, the terminal sends a first message to a first network-side device to request the first network-side device to provide first auxiliary data. The first message carries first information to indicate the tendency of the first auxiliary data requested by the terminal. The first information includes at least one of the following: the regional range of the first auxiliary data, the AI ​​unit association identifier of the first auxiliary data, the use of the first auxiliary data for AI unit training, the use of the first auxiliary data for AI unit inference, and the use of the first auxiliary data for AI unit supervision. The first auxiliary data includes at least one of the following: on-demand positioning reference signal, positioning calculation assistance information, and positioning reference signal configuration information.

[0167] The first network-side device receives a first message from the terminal and can determine the second network-side device based on the first message. The second network-side device may include a radio access network node, such as a base station.

[0168] Optionally, if the first information includes the area range of the first auxiliary data, the first network-side device can determine the second network-side device based on the area range of the first auxiliary data requested by the terminal and / or the serving cell where the terminal is located.

[0169] The second network-side device identified by the first network-side device can be one or more, and can be characterized by the Next Generation-Radio Access Network cell list (NG-RAN cell list).

[0170] The first message enables the first network-side device to accurately determine the required second network-side device.

[0171] In some embodiments of this application, the method may further include the following steps:

[0172] The first network-side device sends a fourth message to the second network-side device, which requests the second network-side device to provide a positioning reference signal configuration. Optionally, the fourth message may also be used to provide the second network-side device with features for on-demand positioning reference signals.

[0173] In this embodiment of the application, after the first network-side device determines the second network-side device based on the first message, it can further send a fourth message to the second network-side device, requesting the second network-side device to send a positioning reference signal with reference to the characteristics of the on-demand positioning reference signal.

[0174] Optionally, the fourth message may include a positioning reference signal configuration request message, such as a PRS CONFIGURATION REQUEST.

[0175] Optionally, the fourth message may carry at least one of the following information:

[0176] On-demand positioning reference signal transmission characteristics;

[0177] A globally unique identifier for a cell associated with an on-demand location reference signal.

[0178] The fourth message sent by the first network-side device to the second network-side device carries at least one of the above-mentioned information, which can clarify the relevant requirements for the positioning reference signal, enabling the second network-side device to provide a suitable positioning reference signal configuration.

[0179] Optionally, the first network-side device may receive a fifth message from the second network-side device, the fifth message being used to provide the first network-side device with a positioning reference signal configuration.

[0180] Optionally, the fifth message may include a positioning reference signal configuration response message, such as PRS CONFIGURATION RESPONSE.

[0181] Optionally, the first network-side device may send a second message to the terminal based on the fifth message.

[0182] In some embodiments of this application, before the first network-side device receives the first message from the terminal, the method may further include the following steps:

[0183] The first network-side device obtains the fourth information from the second network-side device;

[0184] The fourth piece of information includes at least one of the following:

[0185] Location calculation auxiliary information;

[0186] Positioning reference signal auxiliary information;

[0187] Supports on-demand positioning reference signal information.

[0188] In this embodiment, the first network-side device can first obtain the fourth information from the second network-side device. The fourth information can be understood as TRP information. Optionally, the first network-side device can request TRP information from the second network-side device through a TRP information request message, and the first network-side device can receive TRP information from the second network-side device through a TRP information response message.

[0189] Specifically, the fourth type of information may include positioning calculation auxiliary information, such as TPR location information, beam configuration information, synchronization information, and Timing Error Group (TEG) information.

[0190] Alternatively, the fourth piece of information may include positioning reference signal auxiliary information.

[0191] Alternatively, the fourth piece of information may include supported, on-demand positioning reference signal information.

[0192] The first network-side device obtains the fourth information from the second network-side device in advance, which helps to identify the second network-side device based on the first message.

[0193] The technical solution provided by the embodiments of this application allows the terminal to indicate the tendency of the requested auxiliary data through a request auxiliary data message when performing positioning, which helps to further associate other auxiliary data and determine the applicability of the auxiliary data based on the current situation.

[0194] The technical solutions provided in the embodiments of this application have been described above. For ease of understanding, specific examples will be used to illustrate the solutions below.

[0195] In this example, the first network-side device includes an LMF (Local Management Function), and the second network-side device includes a RAN (Radio Ranging Node). The main idea of ​​this example is that when a terminal requests auxiliary data, it lists the expected regional range of the requested auxiliary data (such as a list of Global Cell Identifiers (NCGIs)) or instructs the LMF to include the associated regional range of the auxiliary data in its feedback. This allows the terminal to obtain the globally unique identifier information of the cells associated with the auxiliary data, thereby ensuring cell consistency during training and inference.

[0196] As shown in Figure 4, the corresponding signaling flow is as follows:

[0197] 0. The LMF interacts with RAN nodes to obtain TRP information from the RAN nodes. This can be done through TRP information request / response messages, such as TRP INFORMATION REQUEST / RESPONSE, including at least one of the following:

[0198] Location calculation auxiliary information;

[0199] Positioning reference signal auxiliary information;

[0200] Supports on-demand positioning reference signal information.

[0201] 1. The terminal sends a first request to the LMF (carried by an LPP Request Assistance Data message). The first request is used to request auxiliary data A and includes information A.

[0202] Auxiliary data A includes at least one of the following:

[0203] On-demand positioning reference signals;

[0204] Location calculation auxiliary information;

[0205] Positioning reference signal configuration information.

[0206] This can be understood as the first request being used for at least one of the following: on-demand positioning reference signal request, positioning calculation auxiliary information request, and positioning reference signal configuration information request.

[0207] Information A includes at least one of the following:

[0208] The area range of the auxiliary data A requested by the terminal;

[0209] The AI ​​unit association identifier of the auxiliary data A requested by the terminal;

[0210] The auxiliary data requested by the terminal needs to be associated with the cell's globally unique identifier information, such as NCGI, PCI, ARFCN, etc.

[0211] The reason the terminal requests auxiliary data A is, for example, for AI data collection.

[0212] In this way, the terminal can explicitly list the regional scope of the auxiliary data (such as the NCGI list), or instruct the LMF to include the globally unique identifier of the cell associated with the auxiliary data in the feedback.

[0213] 2. LMF determines RAN nodes (NG-RAN cell list).

[0214] If information A includes the area range of auxiliary data A, then LMF determines the RAN node based on the area range of auxiliary data A;

[0215] If information A does not include the area range of auxiliary data A, then LMF can determine the RAN node based on its own implementation according to the serving cell where the terminal is located.

[0216] 3. The LMF sends a second request (PRS CONFIGURATION REQUEST) to the RAN node to request the RAN node to provide positioning reference signal configuration. Optionally, the second request may also be used to provide the RAN node with the characteristics of the positioning reference signal on demand.

[0217] The second request carries at least one of the following information:

[0218] On-demand positioning reference signal transmission characteristics;

[0219] A globally unique identifier for a cell associated with an on-demand location reference signal.

[0220] 4. The RAN node sends a second response (PRS CONFIGURATION RESPONSE) to the LMF to provide the positioning reference signal configuration.

[0221] 5. The LMF sends a first response to the terminal (carried by an LPP Provide Assistance Data message). The first response is used to provide auxiliary data B and includes information B.

[0222] The first response is the response to the first request.

[0223] Auxiliary data B includes at least one of the following:

[0224] On-demand positioning reference signals;

[0225] Location calculation auxiliary information;

[0226] Positioning reference signal configuration information.

[0227] Information B includes at least one of the following:

[0228] Auxiliary data B is associated with globally unique cell identifiers, such as NCGI, PCI, and ARFCN.

[0229] AI unit association identifier for auxiliary data B.

[0230] Auxiliary data B is used for AI unit training / inference / supervision.

[0231] In this way, LMF may carry the globally unique identifier information of the cell associated with the auxiliary data in the feedback.

[0232] 6. Based on the first response, the terminal performs DL-PRS measurement and acquires the dataset, and then trains the model.

[0233] Model training can be performed by the terminal or by a centralized server, such as an OTT server.

[0234] 7. The terminal sends a third request to the LMF (carried by an LPP Request Assistance Data message). The third request is used to request auxiliary data C and includes information B.

[0235] 8. LMF determines RAN nodes (NG-RAN cell list).

[0236] 9a. The LMF sends a fourth request (PRS CONFIGURATION REQUEST) to the RAN node to request the RAN node to provide positioning reference signal configuration. Optionally, the fourth request may also be used to provide the RAN node with the characteristics of the positioning reference signal on demand;

[0237] The RAN node sends a fourth response (PRS CONFIGURATION RESPONSE) to the LMF to provide the positioning reference signal configuration.

[0238] 10. The LMF sends a third response to the terminal (carried by an LPP Provide Assistance Data message). The third response provides auxiliary data D and includes information C.

[0239] A third response is a response to a third request.

[0240] 11. Based on the third response, the terminal performs DL-PRS measurement and acquires measurement data, and performs model inference.

[0241] If information C is a subset or the entirety of information B, then the terminal determines that the target configuration information used for model training / inference is consistent.

[0242] In step 1, the first request sent by the terminal to the LMF includes information A, informing the LMF of the terminal's preference for the requested auxiliary data A. This allows the LMF to provide auxiliary data B based on the terminal's preference, making the dataset obtained by the terminal based on auxiliary data B more suitable for the current model training process. In step 7, the third request sent by the terminal to the LMF includes information B, which is included in the first response sent by the LMF to the terminal. This ensures that the same network configuration / auxiliary data is obtained during the training and inference phases, helping to improve the accuracy and reliability of AI localization.

[0288] The positioning data transmission method provided in this application embodiment can realize all the processes implemented in the method embodiment shown in Figure 3 and achieve the same technical effect. To avoid repetition, it will not be described again here.

[0289] The positioning data transmission method provided in this application can be executed by a positioning data transmission device. This application uses a positioning data transmission device executing the data transmission method as an example to illustrate the positioning data transmission device provided in this application.

The first message carries first information, which indicates the preference of the requested first auxiliary data. That is, when requesting the first auxiliary data from the first network-side device, the first network-side device is also informed of its own preference for obtaining the first auxiliary data. This allows the first network-side device to provide second auxiliary data based on the preference of the requested first auxiliary data.
