[0066] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0067] There are many ways to implement AI modules (AI models or functions), such as neural networks, decision trees, support vector machines, Bayesian classifiers, etc. This application uses neural networks as an example for illustration, but does not limit the specific type of AI modules.

[0068] The parameters of the neural network are optimized using a gradient optimization algorithm. The gradient optimization algorithm is a type of algorithm that minimizes or maximizes an objective function (sometimes called a loss function), and the objective function is often a mathematical combination of model parameters and data. For example, given data X and its corresponding label Y, we build a neural network model f(.). With the model, we can get the predicted output f(x) based on the input x, and we can calculate the difference between the predicted value and the true value (f(x)-Y), which is the loss function. Find the appropriate W, b to minimize the value of the above loss function. The smaller the loss value, the closer the model is to the actual situation. W is the weight (multiplicative coefficient) and b is the bias (additive coefficient)

[0069] Currently, most common optimization algorithms are based on the back propagation (BP) algorithm. The basic idea of ​​the BP algorithm is that the learning process consists of two steps: forward propagation of signals and back propagation of errors. During forward propagation, input samples are passed from the input layer, processed layer by layer through each hidden layer, and then transmitted to the output layer. If the actual output of the output layer does not match the expected output, the error begins back propagation. Back propagation involves propagating the output error back through the hidden layers to the input layer layer by layer in some form, distributing the error to all units in each layer. This error signal is then generated for each unit in each layer, which serves as the basis for adjusting the weights of each unit. This process of adjusting the weights of each layer, through forward propagation of signals and back propagation of errors, is repeated over and over again. This process of continuous weight adjustment is the network's learning and training process. This process continues until the error in the network output is reduced to an acceptable level, or until a pre-set number of learning cycles is reached.

[0070] Common optimization algorithms include Gradient Descent, Stochastic Gradient Descent (SGD), mini-batch gradient descent, Momentum, Nesterov (name of the inventor, specifically stochastic gradient descent with momentum), Adaptive Gradient Descent (Adagrad), Adadelta, Root Mean Square prop (RMSprop), Adaptive Momentum Estimation (Adam), etc.

[0071] When these optimization algorithms backpropagate errors, they all calculate the derivative / partial derivative of the current neuron based on the error / loss obtained by the loss function, add the influence of the learning rate, the previous gradient / derivative / partial derivative, etc., obtain the gradient, and pass the gradient to the previous layer.

[0072] The AI ​​model or function in this application may also be referred to as an AI unit, an AI model, a machine learning (ML) model, an ML unit, an AI structure, an AI function, an AI feature, a neural network, a neural network function, a neural network function, etc., or the AI ​​model or function may also refer to a processing unit that can implement specific algorithms, formulas, processing procedures, capabilities, etc. related to AI, or the AI ​​model or function may be a processing method, algorithm, function, module or unit for a specific data set, or the AI ​​model or function may be a processing method, algorithm, function, module or unit running on AI / ML related hardware such as a graphics processing unit (GPU), a network processor (NPU), a tensor processing unit (TPU), an integrated circuit for specialized applications (ASIC), etc., and this application does not make specific limitations on this. Optionally, the specific data set includes the input and / or output of the AI ​​model or function.

[0073] Optionally, the identifier of the AI ​​model or function may be an AI model identifier, an AI structure identifier, an AI algorithm identifier, or an identifier of a specific data set associated with the AI ​​model or function, or an identifier of a specific scenario, environment, channel feature, or device related to the AI / ML, or an identifier of a function, feature, capability, or module related to the AI / ML. This application does not specifically limit this.

[0074] In an embodiment of the present application, the AI ​​model or function is an AI positioning model or function.

[0075] The information transmission method, apparatus, and related equipment provided by the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0076] As shown in FIG2 , an information transmission method according to an embodiment of the present application includes:

[0077] Step 21: The terminal receives first information sent by a core network device, where the first information is used to indicate a target artificial intelligence (AI) positioning model or function applied by the terminal, and the target AI positioning model or function is associated with a target antenna configuration applied by an access network device.

[0078] In step 22, the terminal determines the target AI positioning model or function based on the first information.

[0079] In this way, according to steps 21 and 22, the terminal can determine the target AI positioning model or function based on the first information by receiving the first information indicating the target AI positioning model or function applied by the terminal. Since the target antenna configuration applied by the access network device is associated with the target AI positioning model or function, the AI ​​positioning model or function on the terminal side is adapted to the antenna configuration on the access network device side, ensuring the consistency of the training and reasoning of the AI ​​positioning model or function, thereby improving the positioning accuracy.

[0080] Optionally, in this embodiment, the terminal has one or more AI positioning models or functions, and can perform including but not limited to terminal-based angle of departure (UE-based AoD) positioning.

[0081] It should be noted that the terminal obtains channel measurement information by measuring positioning-related reference signals (such as positioning reference signals (PRS)), and inputs the channel measurement information before or after processing into the AI ​​model or function. It can obtain position-related information, such as intermediate feature quantities related to the terminal position (such as indication of LOS / NLOS path, LOS distance between the terminal and TRP, AoD of LOS between the terminal and TRP, etc.) and position coordinates. The position coordinates can be further calculated based on the intermediate feature quantities.

[0082] In this embodiment, the core network device may be a LMF, and the access network device may be a base station or a TRP.

[0083] Optionally, in this embodiment, on the one hand, after the core network device determines the first target information used to indicate the target antenna configuration, it sends the first information to the terminal; on the other hand, after the access network device determines the second target information used to indicate the target antenna configuration, it sends the sixth information to the core network device, and the core network device sends the first information to the terminal based on the sixth information.

[0084] Optionally, in this embodiment, before the terminal receives the first information sent by the core network device, the method further includes:

[0085] The terminal sends third information to the core network device, where the third information is used to indicate the antenna configuration associated with the first AI positioning model or function.

[0086] Here, the first AI positioning model or function may be one or more AI positioning models or functions of the terminal, such as all AI positioning models or functions configured or deployed on the terminal, or the AI ​​positioning model or function that the terminal expects to apply. Moreover, during the training process of the one or more AI positioning models or functions, the data used may be obtained under different antenna configurations. The terminal may collect the third information during data collection.

[0087] In this way, after the core network device receives the third information, it can determine the first target information indicating the target antenna configuration based on the third information, or, combine the third information and the fourth information of the access network device to jointly determine the first target information indicating the target antenna configuration, or, based on the third information, send the fifth information to the access network device so that the access network device determines the second target information indicating the target antenna configuration.

[0088] Among them, if the first AI positioning model or function is the entire AI positioning model or function configured by the terminal, after the core network device determines the first target information, it needs to send the first information to the terminal and send the second information to the access network device to ensure that the subsequent AI positioning model or function applied by the terminal and the antenna configuration applied by the access network device are adapted; if the first AI positioning model or function is the AI ​​positioning model or function that the terminal expects to use, after the core network device determines the first target information, it can only send the second information to the access network device to ensure that the subsequent antenna configuration applied by the access network device and the AI ​​positioning model or function expected to be applied by the terminal are adapted.

[0089] Optionally, in this embodiment, the first information includes at least one of the following items related to the first sending and receiving node:

[0090] Target beam power; target beam width; target beam pointing angle; indication information of target antenna configuration; effective time of target antenna configuration; physical cell identifier; global cell identifier; reference signal identifier; transmitting and receiving node identifier; reference signal resource set identifier; indication information of whether the access network device supports the target antenna configuration; activation time of the target AI positioning model or function; deactivation time of the target AI positioning model or function.

[0091] The first TRP is one or more TRPs communicating with the terminal. The first information includes information related to the first TRP, which can be information related to one or more TRPs communicating with the terminal, or can be understood as information related to one or more cells communicating with the terminal (the cell where the first TRP is located). The first TRP includes but is not limited to: the currently connected TRP, the neighboring TRP, and the predicted TRP to be connected in the future. For example, the first information includes indication information of the target antenna configuration (such as the identifier of antenna configuration 1), the identifiers of all TRPs communicating with the terminal, and the physical cell identifiers of all cells communicating with the terminal.

[0092] Among them, the target beam power, target beam width, and target beam pointing angle are specific parameters of the target antenna configuration. Of course, the target antenna configuration includes but is not limited to the above contents.

[0093] The antenna configuration indication information is used to distinguish different antenna configurations. Identical indication information indicates the same antenna configuration, while different indication information indicates different antenna configurations. For example, if the antenna configuration indication information has index values ​​1 to 10, corresponding to 10 different antenna configurations, the antenna configuration indication information can carry index values ​​1 to 10 to indicate the corresponding antenna configurations. Furthermore, the antenna configuration corresponding to the antenna configuration indication information can be invisible to the terminal. That is, the antenna configuration indication information is only used to distinguish the antenna configurations of different access network devices, thereby protecting the privacy of the access network device's hardware information. Accordingly, the target antenna configuration indication information can be an identifier of the target antenna configuration to represent the target antenna configuration.

[0094] The effective time of the target antenna configuration may include at least one of the effective start time, end time, and duration of the target antenna configuration. For example, the start time is N1 time units after the current time, and the end time is N2 time units after the start time. In this embodiment, the time unit can be a frame, subframe, time slot, orthogonal frequency division multiplexing (OFDM) symbol, month, week, day, hour, minute, second, millisecond, etc.

[0095] The activation time of the target AI positioning model or function is the time when the terminal activates the target AI positioning model or function as instructed by the core network device, such as activation and use after N time units. The deactivation time of the target AI positioning model or function is the time when the terminal deactivates the target AI positioning model or function as instructed by the core network device, such as deactivation and use after M time units after activation.

[0096] Among them, the indication information of whether the access network device supports the target antenna configuration can indicate whether the first TRP supports the target antenna configuration, and can also indicate whether the cell to which the first TRP belongs supports the target antenna configuration.

[0097] Among them, the target beam power includes the beam power of the beam pattern at different spatial angles. The beam power of the beam pattern at different spatial angles is the relative power between several DL-PRS resources of the TRP or the beams associated with the DL-PRS resources at various angles in three-dimensional space. For example, in the direction of azimuth = 10 degrees and elevation = 10 degrees, the relative power corresponding to DL-PRS resource 1 is -2db; the relative power corresponding to DL-PRS resource 2 is -3db, and so on. Specifically, for the Global Coordinate System (GCS), the azimuth is measured counterclockwise from the geographic north; for the Local Coordinate System (LCS), the azimuth is measured counterclockwise from the x-axis of the LCS. Of course, for the Global Coordinate System (GCS), elevation angles are measured relative to the zenith and are positive with respect to the horizontal (elevation 0 degrees points to the zenith, 90 degrees points to the horizon); for the Local Coordinate System (LCS), elevation angles are measured relative to the z-axis of the LCS (elevation 0 degrees points to the z-axis, 90 degrees points to the xy plane).

[0098] Optionally, in this embodiment, the third information includes at least one of the following:

[0099] Beam power of the beam pattern at different spatial angles; beam width; beam pointing angle; indication information of the antenna configuration; physical cell identifier; global cell identifier; reference signal identifier; transmitting and receiving node identifiers; reference signal resource set identifier; timestamp information associated with the first AI positioning model or function; switching delay of the first AI positioning model or function.

[0100] Among them, beam power, beam width, and beam pointing angle are specific parameters of antenna configuration. Of course, antenna configuration includes but is not limited to the above contents.

[0101] Among them, the timestamp information associated with the first AI positioning model or function can be understood as the time of data collection of the first AI positioning model or function. The access network device or core network device contains the antenna configuration record of the access network device at that time, such as the specific beam width and beam pointing angle. Therefore, it can assist in determining the target antenna configuration.

[0102] Among them, the switching delay of the first AI positioning model or function is the time interval between the deactivation of one AI positioning model or function and the activation of another AI positioning model or function, which is related to factors such as device capabilities and model complexity.

[0103] For the third information, the indication information of the antenna configuration, the physical cell identifier (ID), the global cell identifier (ID), the reference signal identifier (ID), the TRP identifier (ID), the reference signal resource set identifier (ID), the timestamp information associated with the first AI positioning model or function, or the switching delay of the first AI positioning model or function, has a corresponding relationship with the antenna configuration. For example, the first information is in the form of a list, different rows map different antenna configurations, and the indication information of the antenna configuration corresponding to one antenna configuration, the physical cell identifier (ID), the global cell identifier (ID), the reference signal identifier (ID), the TRP identifier (ID), the reference signal resource set identifier (ID), the timestamp information associated with the first AI positioning model or function, and the switching delay of the first AI positioning model or function are recorded in the same row.

[0104] It should be noted that the antenna configuration is at least related to the ID of the antenna panel, the orientation of the antenna panel, the number and spacing of antenna elements, and the analog beamforming method or spatial filter used.

[0105] Optionally, the reference signal includes at least one of the following:

[0106] Synchronization Signal and PBCH Block (SSB); Channel State Information Reference Signal (CSI-RS); PRS; Sounding Reference Signal (SRS).

[0107] Through the method of the embodiment of the present application, if the terminal can obtain the antenna configuration associated with the first AI positioning model or function, the antenna configuration is sent to the core network device; if the terminal cannot obtain the antenna configuration associated with the first AI positioning model or function, the terminal sends an indication of the antenna configuration to the core network device to inform the core network device of the antenna configuration associated with the AI ​​positioning model or function. This allows the core network device or access network device to determine the target antenna configuration, so that the terminal receives the first information, applies the target AI positioning model or function, and adapts to the target antenna configuration applied by the access network device, thereby reducing positioning errors.

[0108] As shown in FIG3 , an information transmission method according to an embodiment of the present application includes:

[0109] In step 31, the core network device performs at least one of the following:

[0110] Sending first information to the terminal, where the first information is used to indicate a target artificial intelligence (AI) positioning model or function; and

[0111] Sending second information to the access network device, where the second information is used to indicate a target antenna configuration;

[0112] Among them, the target AI positioning model or function is associated with the target antenna configuration.

[0113] In this way, the core network device sends at least one of the first and second information, enabling the terminal to determine the target AI positioning model or function based on the first information after receiving the first information; and the access network device to adjust the antenna configuration of the application based on the second information after receiving the second information. Ultimately, the AI ​​positioning model or function on the terminal side is adapted to the antenna configuration on the access network device side, improving positioning accuracy.

[0114] In this embodiment, the core network device may be an LMF. The access network device may be a base station or a TRP. If the access network device is a base station, upon receiving the second information, it may further notify one or more corresponding TRPs based on the target antenna configuration; if the access network device is a TRP, the target antenna configuration is an antenna configuration supported by the TRP. Optionally, in this embodiment, before the core network device sends at least one of the first information and the second information, it further includes:

[0115] receiving third information sent by the terminal, where the third information is used to indicate an antenna configuration associated with the first AI positioning model or function;

[0116] Receive fourth information sent by an access network device, where the fourth information is used to indicate an antenna configuration supported by the access network device.

[0117] Here, the first AI positioning model or function can be one or more AI positioning models or functions of the terminal, such as all AI positioning models or functions configured for the terminal, or an AI positioning model or function that the terminal expects to apply. In this way, the core network device can receive the first information sent by the terminal and learn the antenna configuration associated with the first AI positioning model or function. It can also receive the second information sent by the access network device and learn the antenna configuration supported by the access network device, thereby determining the antenna configuration adapted between the terminal and the access network device and reducing positioning errors.

[0118] Optionally, in this embodiment, after the core network device receives at least one of the third information and the fourth information, the method further includes:

[0119] The core network device determines first target information according to at least one of the third information and the fourth information, where the first target information is used to indicate a target antenna configuration;

[0120] The core network device sending first information to the terminal includes:

[0121] The core network device sends the first information to the terminal according to the first target information;

[0122] The core network device sending second information to the access network device includes:

[0123] The core network device sends second information to the access network device according to the first target information.

[0124] That is to say, the core network device will determine the first target information indicating the target antenna configuration, and then send at least one of the first information and the second information. The core network device can determine the antenna configuration (also called the target antenna configuration) that is adapted for the terminal and the access network device based on at least one of the received third information and fourth information, and obtain the first target information indicating the target antenna configuration. Furthermore, the core network device sends the first information to the terminal based on the first target information, instructing the terminal to use the target AI positioning model or function associated with the first target information; and or, sends the second information to the access network device, instructing the access network device to use the target antenna configuration. In this way, the target AI positioning model or function used by the terminal and the target antenna configuration used by the access network device can be adapted.

[0125] For example, the core network device learns from the third information that the antenna configuration associated with the first AI positioning model or function includes configuration 1, configuration 2, and configuration 3, and learns from the fourth information that the antenna configuration supported by the access network device includes configuration 1 and configuration 4. Then, the target antenna configuration indicated by the first target information is one or more of configuration 1, configuration 2, configuration 3, and configuration 4, and the first information is sent to indicate that the target AI positioning model or function used by the terminal is model or function A, and its associated antenna configuration is the target antenna configuration; the second information is sent to indicate that the access network device uses the target antenna configuration (the antenna configuration associated with model or function A). Among them, the determination strategy of the target antenna configuration is pre-set or agreed upon by the protocol, and will not be repeated here.

[0126] Among them, if the first AI positioning model or function is the entire AI positioning model or function configured by the terminal, after the core network device determines the first target information, it needs to send the first information to the terminal and send the second information to the access network device to ensure that the subsequent AI positioning model or function applied by the terminal and the antenna configuration applied by the access network device are adapted; if the first AI positioning model or function is the AI ​​positioning model or function that the terminal expects to use, after the core network device determines the first target information, it can only send the second information to the access network device to ensure that the subsequent antenna configuration applied by the access network device and the AI ​​positioning model or function expected to be applied by the terminal are adapted.

[0127] Among them, if the access network device is a base station, the base station will send the second information to the TRP that supports the target antenna configuration, or the base station will indicate the antenna configuration obtained by parsing the second information to the TRP.

[0128] In addition, the interaction between the terminal and LMF can be through the LTE Positioning Protocol (LPP); the interaction between the access network equipment and LMF can be through the NR Positioning Protocol A (NRPPa).

[0129] Optionally, the third information includes at least one of the following:

[0130] Beam power of the beam pattern at different spatial angles; beam width; beam pointing angle; indication of antenna configuration; physical cell identifier; global cell identifier; reference signal identifier; transmitting and receiving node identifiers; reference signal resource set identifier; timestamp information associated with the first AI positioning model or function; switching delay of the first AI positioning model or function;

[0131] The fourth information includes at least one of the following:

[0132] Beam power of the beam pattern at different spatial angles; beam width; beam pointing angle; antenna configuration indication information; physical cell identifier; global cell identifier; reference signal identifier; transmitting and receiving node identifier; reference signal resource set identifier; antenna configuration switching delay.

[0133] The antenna configuration indication information is used to distinguish different antenna configurations. Identical indication information indicates the same antenna configuration, while different indication information indicates different antenna configurations. For example, if the antenna configuration indication information has index values ​​1 to 10, corresponding to 10 different antenna configurations, the antenna configuration indication information can carry index values ​​1 to 10 to indicate the corresponding antenna configurations. Furthermore, the antenna information corresponding to the antenna configuration indication information can be invisible to the terminal. That is, the antenna configuration indication information is only used to distinguish the antenna configurations of different access network devices, thereby protecting the privacy of the access network device's hardware information.

[0134] Among them, the timestamp information associated with the first AI positioning model or function can be understood as the time of data collection of the first AI positioning model or function. The access network device or core network device contains the antenna configuration record of the access network device at that time, such as the specific antenna configuration. Therefore, it can assist in determining the target antenna configuration.

[0135] It should be known that the indication information of the antenna configuration in the third information, the physical cell identifier (ID), the global cell identifier (ID), the reference signal identifier (ID), the TRP identifier (ID), the reference signal resource set identifier (ID), the timestamp information associated with the first AI positioning model or function, or the switching delay of the first AI positioning model or function, has a corresponding relationship with the antenna configuration. For example, the first information is in the form of a list, different rows map different antenna configurations, and the same row records the indication information of the antenna configuration corresponding to an antenna configuration, the physical cell identifier (ID), the global cell identifier (ID), the reference signal identifier (ID), the TRP identifier (ID), the reference signal resource set identifier (ID), the timestamp information associated with the first AI positioning model or function, and the switching delay of the first AI positioning model or function. Similarly, the indication information of the antenna configuration, the physical cell identifier (ID), the global cell identifier (ID), the reference signal identifier (ID), the TRP identifier (ID), the reference signal resource set identifier (ID), and the switching delay of the antenna configuration in the fourth information also have a corresponding relationship with the antenna configuration, which will not be repeated here.

[0136] For the third information, at least one of the above-mentioned antenna configuration, indication information of the antenna configuration, physical cell identifier (ID), global cell identifier (ID), reference signal identifier (ID), TRP identifier (ID), reference signal resource set identifier (ID), timestamp information associated with the first AI positioning model or function, and switching delay of the first AI positioning model or function is information related to one or more TRPs communicating with the terminal, or can also be understood as information related to one or more cells communicating with the terminal. Among them, TRP or cell includes but is not limited to: currently connected TRP or cell, neighboring TRP or cell, predicted TRP or cell to be connected in the future.

[0137] For the fourth information, at least one of the above-mentioned antenna configuration, antenna configuration indication information, physical cell identifier (ID), global cell identifier (ID), reference signal identifier (ID), TRP identifier (ID), reference signal resource set identifier (ID), and antenna configuration switching delay is information related to the TRP of the access network device, or can also be understood as cell-related information of the access network device.

[0138] The switching delay of the first AI positioning model or function is the time interval between the deactivation of one AI positioning model or function and the activation of another AI positioning model or function, which is related to factors such as device capabilities and model complexity. That is, the terminal can inform the core network device of its switching delay between AI positioning models or functions through the third information to assist in determining the target antenna configuration. The access network device can inform the core network device of its switching delay between antenna configurations through the fourth information to assist the core network device in determining the target antenna configuration.

[0139] Optionally, the first information or the second information includes first target information, or the first information or the second information may not include the first target information.

[0140] Optionally, the first information includes at least one of the following items related to the first sending and receiving node:

[0141] Target beam power; target beam width; target beam pointing angle; indication of target antenna configuration; effective time of target antenna configuration; physical cell identifier; global cell identifier; reference signal identifier; transmitting and receiving node identifiers; reference signal resource set identifier; indication of whether the access network device supports the target antenna configuration; activation time of the target AI positioning model or function; deactivation time of the target AI positioning model or function;

[0142] The second information includes at least one of the following items related to the second sending and receiving node:

[0143] Target beam power; target beam width; target beam pointing angle; indication information of target antenna configuration; effective time of target antenna configuration; physical cell identifier; global cell identifier; reference signal identifier; transmitting and receiving node identifier; reference signal resource set identifier; indication information of whether the access network device supports the target antenna configuration;

[0144] The first sending and receiving node includes one or more sending and receiving nodes communicating with the terminal; the second sending and receiving node includes a sending and receiving node of the access network device.

[0145] The first TRP is one or more TRPs communicating with the terminal. The first information includes information related to the first TRP, which can be information related to one or more TRPs communicating with the terminal, or information related to one or more cells communicating with the terminal (the cell where the first TRP is located). The first TRP includes but is not limited to: the currently connected TRP, the neighboring TRP, and the predicted TRP to be connected in the future.

[0146] The effective time of the target antenna configuration may include at least one of the effective start time, end time, and duration of the target antenna configuration. For example, the start time is N1 time units after the current time, and the end time is N2 time units after the start time. In this embodiment, the time unit may be a frame, subframe, time slot, OFDM symbol, month, week, day, hour, minute, second, millisecond, etc.

[0147] The activation time of the target AI positioning model or function is the time when the terminal activates the target AI positioning model or function as instructed by the core network device, such as activation and use after N time units. The deactivation time of the target AI positioning model or function is the time when the terminal deactivates the target AI positioning model or function as instructed by the core network device, such as deactivation and use after M time units after activation.

[0148] Optionally, the activation time of the target AI positioning model or function is after the effective start time of the target antenna configuration, N≥N1; at the same time, the deactivation time of the target AI positioning model or function should be before the expiration time of the target antenna configuration; thereby ensuring that the target AI positioning model or function always matches the antenna configuration of the access network device during operation.

[0149] Among them, the first information includes indication information on whether the access network device supports the target antenna configuration, which can indicate whether the first TRP supports the target antenna configuration, and can also indicate whether the cell to which the first TRP belongs supports the target antenna configuration.

[0150] The core network device sends the second information to the access network device. Since the second information includes information related to the second TRP, it can be understood as sending information related to the TRP of the access network device, or it can be understood as sending information related to the cell of the access network device (the cell to which the TRP of the access network device belongs). Among them, the TRP or cell supports the target antenna configuration. In this way, the second information includes the indication information of whether the access network device supports the target antenna configuration, which can indicate whether the second TRP supports the target antenna configuration, and can also indicate whether the cell to which the second TRP belongs supports the target antenna configuration. Second

[0151] For example, after the core network device determines the first target information, it sends the first information including the physical cell ID, reference signal ID, reference signal resource set ID, transmitting and receiving point ID, the effective time of the target antenna configuration, the indication information of the target antenna configuration, the activation time of the target AI positioning model or function, and the deactivation time of the target AI positioning model or function. Among these information, the physical cell ID, reference signal ID, reference signal resource set ID, and transmitting and receiving point ID are information related to one or more cells; the second information sent includes the cell ID, reference signal ID, reference signal resource set ID, transmitting and receiving point ID, the effective time of the target antenna configuration, and the indication information of the target antenna configuration. Among these information, the physical cell ID, reference signal ID, reference signal resource set ID, and transmitting and receiving point ID are only relevant information of cell 1, and cell 1 (TRP of cell 1) supports the target antenna configuration.

[0152] Additionally, optionally, in this embodiment, the method further includes:

[0153] The core network device sends fifth information to the access network device based on the third information, where the fifth information is used to indicate the antenna configuration associated with the first artificial intelligence (AI) positioning model or function;

[0154] The core network device receives sixth information sent by the access network device, where the sixth information includes second target information, where the second target information is used to indicate a target antenna configuration;

[0155] The core network device sending first information to the terminal includes:

[0156] The core network device sends the first information to the terminal according to the sixth information.

[0157] That is, the access network device determines second target information indicating the target antenna configuration. To enable the access network device to determine the second target information, the core network device sends fifth information indicating the antenna configuration associated with the first AI positioning model or function to the access network device based on the third information. The fifth information may be the same as or different from the third information and will not be further described here.

[0158] Based on the fifth information received and the antenna configuration supported by itself, the access network device can determine the antenna configuration (also called the target antenna configuration) that is adapted to the terminal, that is, it can determine the second target information indicating the target antenna configuration. Furthermore, the access network device sends the sixth information to the core network device, and the sixth information includes the second target information. Afterwards, the core network device sends the first information to the terminal based on the sixth information, instructing the terminal to use the target AI positioning model or function associated with the second target information. Of course, the access network device will also use the target antenna configuration. In this way, the target AI positioning model or function used by subsequent terminals and the target antenna configuration used by the access network device are adapted.

[0159] Among them, if the access network device is a base station, the base station will determine the target antenna configuration in combination with the antenna configuration supported by one or more TRPs, and then notify the TRP that supports the target antenna configuration to use the target antenna configuration.

[0160] Optionally, the sixth information includes at least one of the following items related to the third sending and receiving node:

[0161] Target beam power; target beam width; target beam pointing angle; indication of target antenna configuration; effective time of target antenna configuration; physical cell identifier; global cell identifier; reference signal identifier; transmitting and receiving node identifiers; reference signal resource set identifier; indication of whether the access network device supports the target antenna configuration; activation time of the target AI positioning model or function; deactivation time of the target AI positioning model or function;

[0162] The third sending and receiving node includes a sending and receiving node of the access network device.

[0163] Here, the sixth information is sent by the access network device to the core network device, and the third TRP is the TRP of the access network device. For example, if the access network device is a TRP, the third TRP sends information related to itself to the core network device, or information about the cell to which it belongs; if the access network device is a base station, the base station sends information related to the third TRP (one or more TRPs) included in it to the core network device, or information about the cell to which the third TRP belongs. Specifically, the third TRP or its cell supports the target antenna configuration.

[0164] The information related to the third TRP may be information related to the TRP of the access network device, or may be understood as information related to a cell of the access network device, wherein the TRP or cell supports the target antenna configuration.

[0165] For example, after the access network device determines the second target information, it sends the sixth information including the physical cell ID, reference signal ID, reference signal resource set ID, transmit and receive point ID, target antenna configuration effective time, target antenna configuration indication information, target AI positioning model or function activation time, target AI positioning model or function deactivation time, where the physical cell ID, reference signal ID, reference signal resource set ID, and transmit and receive point ID in this information are only relevant information of cell 2, and cell 2 (TRP of cell 2) supports the target antenna configuration. The first information may be the same as or different from the sixth information.

[0166] Optionally, in this embodiment, the first information includes at least part of the eighth information;

[0167] Before the core network device sends the first information to the terminal, the method further includes:

[0168] The core network device determines eighth information based on the sixth information.

[0169] That is, after receiving the sixth information, the core network device first determines the eighth information and then sends the first information, which includes at least a portion of the eighth information. Here, the eighth information is derived based on the sixth information and may include the target antenna configuration, information indicating the target antenna configuration, etc., while the first information may only include information indicating the target antenna configuration. Of course, the first information may be the same as the eighth information.

[0170] Optionally, in this embodiment, the beam power of the beam pattern at different spatial angles is the relative power at each angle in three-dimensional space between several DL-PRS resources of the TRP or beams associated with the DL-PRS resources. For example, in the direction of azimuth = 10 degrees and elevation = 10 degrees, the relative power corresponding to DL-PRS resource 1 is -2dB; the relative power corresponding to DL-PRS resource 2 is -3dB, and so on.

[0171] Specifically, for the Global Coordinate System (GCS), azimuth is measured counterclockwise from geographic north; for the Local Coordinate System (LCS), azimuth is measured counterclockwise from the x-axis of the LCS. Of course, for the Global Coordinate System (GCS), elevation is measured relative to the zenith and is positive to the horizontal (0 degrees elevation points to the zenith and 90 degrees points to the horizon); for the Local Coordinate System (LCS), elevation is measured relative to the z-axis of the LCS (0 degrees elevation points to the z-axis and 90 degrees points to the xy plane).

[0172] It should be noted that the antenna configuration is at least related to the ID of the antenna panel, the orientation of the antenna panel, the number and spacing of antenna elements, and the analog beamforming method or spatial filter used.

[0173] Optionally, the reference signal includes at least one of the following:

[0174] Synchronization Signal and PBCH Block (SSB); Channel State Information Reference Signal (CSI-RS); Positioning Reference Signal (PRS); Sounding Reference Signal (SRS).

[0175] In this embodiment, when the antenna configuration of the access network device changes, the access network device can also combine the fifth information of the core network device to obtain the antenna configuration associated with the first AI positioning model or function reported by the terminal, determine the target antenna configuration, and send the first information to the terminal; or, the access network device notifies the core network device that the antenna configuration currently applied by the access network device has changed, triggering the core network device to determine the target antenna configuration, and send the first information to the terminal and the second information to the access network device. In this way, the antenna configuration change of the access network device can be adapted so that the AI ​​positioning model or function used by the terminal and the antenna configuration used by the access network device are adapted, thereby reducing positioning errors.

[0176] To summarize, the core network device can receive the third information sent by the terminal to learn the antenna configuration associated with the AI ​​positioning model or function, and can receive the fourth information sent by the access network device to learn the antenna configuration supported by the access network device, thereby determining the target antenna configuration adapted between the terminal and the access network device. Afterwards, the core network device sends the first information to the terminal, and the terminal can determine the target AI positioning model or function associated with the target antenna configuration based on the first information. The core network device sends the second information to the access network device, so that the access network device can adjust the applied antenna configuration based on the second information to adapt to the terminal's AI positioning model or function. This improves the accuracy of the terminal's AI positioning.

[0177] It should be noted that the method of the embodiment of the present application is implemented in conjunction with the above-mentioned information transmission method on the terminal side. The implementation method of the above-mentioned method embodiment is applicable to this method and can also achieve the same technical effect.

[0178] As shown in FIG4 , an information transmission method according to an embodiment of the present application includes:

[0179] In step 41, the access network device performs one of the following:

[0180] receiving second information sent by a core network device, where the second information is used to indicate a target antenna configuration;

[0181] Sending sixth information to the core network device, where the sixth information includes second target information, where the second target information is used to indicate a target antenna configuration;

[0182] Among them, the target antenna configuration is associated with the target AI positioning model or function of the terminal application.

[0183] In this way, the access network device can adjust the applied antenna configuration based on the second information to adapt to the terminal's AI positioning model or function, thereby improving positioning accuracy. The access network device can also send sixth information indicating the target antenna configuration to the core network device, so that the core network device notifies the terminal of the first information, so that the terminal can determine the target AI positioning model or function through the first information.

[0184] Optionally, before the access network device receives the second information sent by the core network device, the method further includes:

[0185] The access network device sends fourth information to the core network device, where the fourth information is used to indicate the antenna configuration supported by the access network device.

[0186] In this way, the access network device can provide the core network device with the antenna configurations it supports, providing a basis for subsequently determining the antenna configuration adapted between the terminal and the access network device, thereby reducing positioning errors.

[0187] It should be noted that after the terminal sends the third information to the core network device, the core network device determines the first target information based on the third information and sends the second information; or the core network device also receives the fourth information sent by the access network device, combines the third and fourth information to determine the first target information, and sends the second information. If the terminal does not send the third information to the core network device, the core network device receives the fourth information sent by the access network device, and may determine the first target information based on the fourth information and send the second information.

[0188] Optionally, before the access network device sends the sixth information to the core network device, the method further includes:

[0189] The access network device receives fifth information sent by the core network device, where the fifth information is used to indicate an antenna configuration associated with the first AI positioning model or function;

[0190] The access network device sends sixth information to the core network device, including:

[0191] The access network device sends the sixth information according to the fifth information.

[0192] That is, by receiving the fifth information sent by the core network device to the access network device, the target antenna configuration can be determined autonomously in the subsequent process and the sixth information is returned to the core network device, thereby reducing the positioning error.

[0193] Optionally, the method further includes:

[0194] The access network device adjusts the antenna configuration used according to the second information.

[0195] In this way, the access network equipment can adjust (switch) the antenna configuration, apply the target antenna configuration, adapt to the terminal target AI positioning model or function, and improve positioning accuracy.

[0196] Optionally, the third information includes at least one of the following:

[0205] The first sending and receiving node includes one or more sending and receiving nodes communicating with the terminal; the second sending and receiving node includes a sending and receiving node of the access network device.

[0206] Optionally, the sixth information includes at least one of the following items related to the third sending and receiving node:

[0207] Target beam power; target beam width; target beam pointing angle; indication of target antenna configuration; effective time of target antenna configuration; physical cell identifier; global cell identifier; reference signal identifier; transmitting and receiving node identifiers; reference signal resource set identifier; indication of whether the access network device supports the target antenna configuration; activation time of the target AI positioning model or function; deactivation time of the target AI positioning model or function;

[0209] Optionally, the reference signal includes at least one of the following:

[0210] Synchronization signal block SSB; channel state information reference signal CSI-RS; positioning reference signal PRS; signal sounding reference signal SRS.

[0211] The information transmission method provided in the embodiment of the present application can be executed by an information transmission device. In the embodiment of the present application, the information transmission device provided in the embodiment of the present application is described by taking the information transmission method executed by the information transmission device as an example.

[0212] As shown in FIG5 , an information transmission device according to an embodiment of the present application includes:

[0213] A first transmission module 51 is configured to receive first information sent by a core network device, where the first information is used to indicate a target artificial intelligence (AI) positioning model or function applied by the terminal, and the target AI positioning model or function is associated with a target antenna configuration applied by the access network device;

[0214] The first processing module 52 is configured to determine the target AI positioning model or function based on the first information.

[0215] By receiving first information indicating the target AI positioning model or function applied by the terminal, the device can determine the target AI positioning model or function based on the first information. Since the target antenna configuration applied by the access network device is associated with the target AI positioning model or function, the AI ​​positioning model or function on the terminal side is adapted to the antenna configuration on the access network device side, ensuring the consistency of AI positioning model or function training and reasoning, thereby improving positioning accuracy.

[0228] The target AI positioning model or function is associated with the target antenna configuration. The device transmits at least one of the first information and the second information, so that the terminal, upon receiving the first information, can determine the target AI positioning model or function based on the first information; and the access network device, upon receiving the second information, can adjust the antenna configuration of the application based on the second information. Ultimately, the AI ​​positioning model or function on the terminal side is adapted to the antenna configuration on the access network device side, thereby improving positioning accuracy.
