[0003] Currently, the terminal or access network equipment can first measure and process the reference signal to obtain relevant measurement information. This relevant measurement information includes multiple information units (e.g., multiple channel paths), and then determine some information units from these multiple information units. These information units are then reported so that the Location Management Function (LMF) network element can determine the terminal's location information based on these information units.

[0004] However, since the determination rules for the aforementioned information units in the current protocol are determined by the terminal or access network equipment, when the LMF network element determines the terminal's location information based on these information units and the Artificial Intelligence (AI) model, the determination rules for these information units may not match (e.g., they are different, have low correlation, or have large differences) with the determination rules for the information units in the training dataset associated with the AI ​​model.

[0021] In this embodiment, the second device can send first auxiliary information to the first device, which is related to predefined rules, and receive second measurement information from the first device, including N first information units, where N is a positive integer. The second device can then determine the terminal's location information based on this second measurement information. The predefined rules are used to determine N first information units from the first measurement information, which is measurement information associated with a first reference signal used for locating the terminal. Since the predefined rules are predetermined, other devices can also acquire these predefined rules when training the second device's AI model and determine the reported information units from the measurement information based on these rules. This ensures that the determination rules for each information unit in the training dataset associated with the second device's AI model match the predefined rules (e.g., are the same, have high correlation, or have low difference). In this way, after the second device instructs the first device on the relevant information of the predefined rules through the first auxiliary information and receives the second measurement information from the first device, when the second device determines the location information of the terminal based on the N first information units in the second measurement information and the AI ​​model, because the rules for determining the reported N first information units (i.e., the predefined rules) of the first device match the rules for determining the information units of the training dataset associated with the AI ​​model of the second device (e.g., they are the same, or have a high correlation, or have a small difference), the probability of the terminal location information output by the AI ​​model being inaccurate due to the mismatch between the rules for determining the N first information units of the first device and the rules for determining the information units of the training dataset associated with the AI ​​model can be reduced. This can improve the accuracy of the terminal location information determined by the second device, thereby improving the accuracy of terminal positioning. Attached Figure Description

[0038] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0039] The following will explain the technical terms used in the embodiments of this application.

[0040] 1. AI Model

[0041] Currently, AI models have been widely applied in various fields. Integrating AI models into wireless communication networks can significantly improve technical indicators such as throughput, latency, and user capacity, which is also an important task for future wireless communication networks. AI models can be implemented in various ways, such as neural networks, decision trees, support vector machines, and Bayesian classifiers. This application uses a neural network as an example for illustration, but it does not limit the specific type of AI model.

[0042] The parameters of the neural network are optimized using gradient optimization algorithms. Gradient optimization algorithms are a class of algorithms that minimize or maximize an objective function (sometimes called a loss function), which is often a mathematical combination of model parameters and data. For example, given data X and its corresponding label Y, a neural network model f(.) can be constructed. With the model, the predicted output f(x) can be obtained from the input x, and the difference between the predicted value and the true value (f(x)-Y) can be calculated; this is the loss function. Thus, by finding appropriate weights (multiplicative coefficients) and biases (additive coefficients), the value of the above loss function can be minimized. The smaller the loss value, the closer the AI ​​model's output is to the reality.

[0043] Typically, common optimization algorithms are based on the error back propagation (BP) algorithm. The basic idea of ​​the BP algorithm is that the learning process consists of two processes: forward propagation of the signal and backward propagation of the error. During forward propagation, the input sample is introduced from the input layer, processed layer by layer by the hidden layers, and then propagated to the output layer. If the actual output of the output layer does not match the expected output, the process transitions to the error back propagation stage. Error back propagation involves propagating the output error back to the input layer layer by layer through the hidden layers, distributing the error to all units in each layer, thereby obtaining the error signal of each unit. This error signal serves as the basis for adjusting the weights of each unit. This process of adjusting the weights through forward and backward propagation is repeated continuously. This continuous adjustment of weights is the learning and training process of the network. This process continues until the error of the network output is reduced to an acceptable level, or until the predetermined number of learning iterations is reached.

[0044] Common optimization algorithms include Gradient Descent, Stochastic Gradient Descent (SGD), Mini-Batch Gradient Descent, Momentum, Nesterov, Adaptive Gradient Descent (Adagrad), Adaptive Delta (Adadelta), Root Mean Square Probe (RMSprop), and Adaptive Moment Estimation (Adam).

[0045] During error backpropagation, these optimization algorithms calculate the gradient based on the error / loss obtained from the loss function with respect to the current neuron, add the learning rate, previous gradients / derivatives / partial derivatives, etc., and then pass the gradient to the previous layer.

[0046] It should be noted that the AI ​​unit / AI model in the embodiments of this application may also be referred to as AI unit, AI model, machine learning (ML) model, ML unit, AI structure, AI function, AI characteristic, machine learning model, neural network, neural network function, neural network functionality, etc. Alternatively, an AI unit / AI model may refer to a processing unit capable of implementing specific algorithms, formulas, processing flows, capabilities, etc., related to AI. Alternatively, an AI unit / AI model may be a processing method, algorithm, function, module, or unit for a specific dataset. Alternatively, an AI unit / AI model may be a processing method, algorithm, function, module, or unit running on AI / ML related hardware such as a graphics processing unit (GPU), neural network processing unit (NPU), tensor processing unit (TPU), or application-specific integrated circuit (ASIC). This invention does not specifically limit its scope in this regard. Optionally, the specific dataset includes the input and / or output of the AI ​​unit / AI model.

[0047] The identifiers of the aforementioned AI units / AI models may be AI model identifiers, AI structure identifiers, AI algorithm identifiers, or identifiers of specific datasets associated with AI units / AI models, or identifiers of specific scenarios, environments, channel characteristics, or devices related to AI / ML, or identifiers of functions, characteristics, capabilities, or modules related to AI / ML. This application does not specifically limit these identifiers.

[0048] 2. Channel sampling points

[0049] Typically, channel sampling points, also known as sampling of the time-domain channel response or sampling points of the time-domain channel response, are observations or measurements of the time-domain channel response obtained at a certain time granularity T.

[0050] The measurement based on channel sampling points is defined as follows: a. The measurement consists of Nt' estimated time-domain channel response sampling points. The time information of the Nt' sampling points is reported in time granularity T, where T = 2^T. kxTc, k represents the granularity coefficient of the report. Tc is the basic time unit for New Radio (NR). b. The corresponding measurement (such as the reported power) corresponds to the measurement at the reported Nt' sampling point. c. Nt' and k can be indicated. d. Time information is defined relative to a reference time.

[0051] Suppose there are L complex gain {C} a ,l} l and delay {τ l} l The actual channel tap. At the receiving antenna port a, the... The reference symbols (positioning reference signals (PRS) or sounding reference signals (SRS)) received at each subcarrier are given by the following formula:

[0052] Where k = -N / 2, -N / 2+1, ..., N / 2-1;

[0053] Where N represents the number of subcarriers carrying reference symbols (e.g., N = 3264); Δ f Indicates the subcarrier spacing (e.g., Δ). f =30kHz); S k Indicates the first Known PRS or SRS on each subcarrier; W′ a [k] represents the received noise.

[0054] The measured channel frequency response samples are shown below:

[0055] in, For s k . conjugate.

[0056] Assumption: N FFT >N represents the window size for one Fast Fourier Transform (FFT) (e.g., N0). FFT =4096); N FFT Δ f Indicates the sampling rate (e.g., 4096 × 30 kHz = 122.88 MHz); d l =τ l ·(N FFT Δ f ) represents the channel tap delay expressed in terms of the sampling period.

[0057] Then, the channel frequency response can be expressed as:

[0058] The inverse fast fourier transform (IFFT) of the frequency domain channel response sampling points is used to obtain the measured channel impulse response (CIR) sampling points:

[0059] Where d = 0, 1, ..., N FFT -1, and W a [d] is W a IFFT of [k].

[0060] Because of the above formula The real channel tap can induce a time domain (TD) response at a large number of measurement sampling points, with a large response near the real delay and attenuation at sampling points far from the real delay.

[0061] Note that these time-domain or frequency-domain channel measurement sampling points are directly observable at the receiver or receiver unit. These measurement sampling points can be further processed in the following ways.

[0062] By retaining only the first N t Sample points and discard the last N. FFT -N t Each sampling point obtains a truncated TD CIR from the TD CIR.

[0063] By retaining only the power information at the antenna port at each sampling grid point, the TD power delay profile (PDP) is obtained from the (truncated) TD CIR:

[0064] By using N′ with maximum power t The sampling points are set to specific values, and the time-domain delay spectrum (TD DP) is obtained from the TD PDP of the sub-sampling points. The specific value can be a constant, such as 1, or the reference signal received power (RSRSRP) of the link.

[0065] RSRP = ∑p[d]

[0066] 3. Channel path

[0067] Channel path is an estimate of the channel response, such as the time-domain channel impulse response or channel frequency response, obtained by measuring a reference signal and further processed by a multipath extraction algorithm. Specifically, the result of the multipath extraction or estimation algorithm is an estimate of the actual propagation path of a signal in a real-world environment, including the path's delay, power, and phase, which respectively describe the changes in delay, power, and phase experienced by the wireless signal as it travels along that propagation path.

[0068] Furthermore, the current protocol supports path-based reporting, allowing the reporting of the primary path and up to eight additional paths. These nine paths are used by a second device to confirm the true direct path, such as selecting the Nth path as the direct path (also known as the line of sight (LOS)). However, the protocol does not constrain how these paths are determined; it depends on the implementation of the terminal and / or access network equipment and / or the Positioning Reference Unit (PRU).

[0098] In some embodiments of this application, the above-mentioned N first information units include at least one of the following:

[0099] At least one delay information;

[0100] At least one power information;

[0101] At least one phase information.

[0102] In some embodiments of this application, when the unit type of the N first information units includes channel sampling points, the N first information units may include at least one of the following:

[0103] Delay information for at least one channel sampling point;

[0104] Delay and power information for at least one channel sampling point;

[0105] Delay information, power information, and phase information of at least one channel sampling point.

[0106] In some embodiments of this application, when the element type of the N first information elements includes a channel path, the N first information elements may include at least one of the following:

[0107] Delay information for at least one channel path;

[0108] Delay and power information for at least one channel path;

[0109] At least one channel path's delay information, power information, and phase information.

[0110] In some embodiments of this application, when N first information units include at least one delay information, the number of first information units and the number of delay information may be the same or different. It is understood that, since each first information unit may include one delay information, the number of first information units and the number of delay information may be the same; or, since some first information units may include one delay information in each unit, while other first information units may not include delay information in each unit, the number of first information units and the number of delay information may be different.

[0111] In some embodiments of this application, when N first information units include at least one power information, the number of first information units and the number of power information units may be the same or different. It is understood that, since there may be a case where each first information unit includes one power information unit, the number of first information units and the number of power information units may be the same; or, since there may be a case where each first information unit in some first information units includes one power information unit, while each first information unit in other first information units does not include power information, the number of first information units and the number of power information units may be different.

[0112] In some embodiments of this application, when N first information units include at least one phase information, the number of first information units and the number of phase information may be the same or different. It is understood that, since each first information unit may include one phase information, the number of first information units and the number of phase information may be the same; or, since some first information units may include one phase information in each unit, while other first information units may not include phase information in each unit, the number of first information units and the number of phase information may be different.

[0113] Thus, since the embodiments of this application specify the specific content included in the N first information units, the first device can accurately determine the N first information units from the first measurement information and report the second measurement information including the accurate N first information units to the second device, so that the second device can accurately determine the location information of the terminal.

[0114] In some embodiments of this application, when the N first information units include at least one time delay information and at least one power information, the at least one time delay information and the at least one power information correspond one-to-one, and each time delay information and its corresponding power information are associated with the same first information unit.

[0115] For example, suppose the N first information units include N delay information and N power information, and the unit type of the N first information units is a channel sampling point. Then, the i-th delay information in the N delay information and the i-th power information in the N power information are associated with the same channel sampling point (e.g., the i-th channel sampling point in the N channel sampling points), and the i-th delay information corresponds to the i-th power information. Here, i is a positive integer.

[0116] For example, suppose N first information units include N delay information and N power information, and the unit type of the N first information units is a channel path. Then, the j-th delay information in the N delay information and the j-th power information in the N power information are associated with the same channel path (e.g., the j-th channel path in the N channel paths), and the j-th delay information corresponds to the j-th power information. Here, j is a positive integer.

[0117] Thus, since the embodiments of this application specify the conditions that at least one delay information and at least one power information must satisfy when the N first information units include at least one delay information and at least one power information, the second device can accurately determine the location information of the terminal after reporting the N first information units to the second device.

[0118] In some embodiments of this application, when the N first information units include at least one time delay information, at least one power information and at least one phase information, the at least one time delay information, at least one power information and at least one phase information correspond one-to-one, and each time delay information, its corresponding power information and its corresponding phase information are associated with the same first information unit.

[0119] For example, suppose the N first information units include N time delay information, N power information, and N phase information, and the unit type of the N first information units is a channel sampling point. Then, the x-th time delay information, the x-th power information, and the x-th phase information among the N time delay information are associated with the same channel sampling point (e.g., the x-th channel sampling point among the N channel sampling points). The x-th time delay information corresponds to the x-th power information, and the x-th power information corresponds to the x-th phase information. Here, x is a positive integer.

[0120] For example, suppose N first information units include N time delay information, N power information, and N phase information, and the unit type of the N first information units is a channel path. Then, the y-th time delay information, the y-th power information, and the y-th phase information among the N time delay information, are associated with the same channel path (e.g., the y-th channel path among the N channel paths). The y-th time delay information corresponds to the y-th power information, and the y-th power information corresponds to the y-th phase information. Here, y is a positive integer.

[0121] Thus, since the embodiments of this application specify the conditions that at least one delay information, at least one power information, and at least one phase information must satisfy when the N first information units include at least one delay information, at least one power information, and at least one phase information, the second device can accurately determine the location information of the terminal after reporting the N first information units to the second device.

[0122] In some embodiments of this application, when N first information units include at least one phase information and the number of first information units associated with at least one phase information is 1, the first information unit associated with at least one phase information satisfies at least one of the following:

[0123] The information unit with the smallest time delay information among N first information units;

[0124] Among the N first information units, the information unit with the largest amplitude or power information;

[0125] The first information unit among N first information units.

[0126] It can be understood that when at least one phase information belongs to a first information unit, the first information unit can be the information unit with the smallest time delay information among N first information units, and / or the information unit with the largest amplitude information or power information among N first information units, and / or the first information unit among N first information units.

[0127] In some embodiments of this application, when the unit type of the N first information units is a channel path, if the N first information units include at least one phase information and the number of first information units associated with at least one phase information is 1, then the first information unit associated with at least one phase information can satisfy at least one of the following: the information unit with the smallest delay information among the N first information units, the information unit with the largest amplitude information or power information among the N first information units, and the first information unit among the N first information units.

[0128] Thus, since the embodiments of this application specify the conditions that a first information unit must satisfy when N first information units include at least one phase information and the number of first information units associated with at least one phase information is 1, the second device can accurately determine the location information of the terminal after reporting the N first information units to the second device.

[0129] In some embodiments of this application, the above-mentioned predefined rules satisfy at least one of the following: they are agreed upon by the protocol, they are pre-configured by the second device, or they are pre-configured by other devices.

[0130] It is understood that the above-mentioned predefined rules are agreed upon by the protocol and / or pre-configured by the second device and / or other devices. That is, the predefined rules are rules that the first device has already obtained before the first device determines the information unit to be reported (i.e., N first information units). Therefore, it can be ensured that the first device determines the first information unit in the same way as other devices determine the information unit to be reported.

[0131] In some embodiments of this application, the above-defined rules include at least one of the following:

[0132] From the first measurement information, determine the top N information units with the largest amplitude or power information;

[0133] Determine the N information units with the smallest time delay information from the first measurement information;

[0134] From the first measurement information, determine the information unit with the smallest time delay information, and the top N-1 information units with the largest amplitude or power information other than the information unit with the smallest time delay information;

[0135] From the first measurement information, determine the information unit with the largest amplitude or power information, and the first N-1 information units with the smallest time delay information other than the information unit with the largest amplitude or power information.

[0136] In some embodiments of this application, the first device may first determine the power information or phase information included in the M second information units, and then determine the top N information units with the largest power information from the M second information units; or, it may determine the amplitude information included in the M second information units based on the phase information included in the M second information units, and determine the top N information units with the largest amplitude information from the M second information units, so as to determine the N first information units.

[0137] It is understood that the larger the amplitude or power information of an information unit, the higher the correlation between that information unit and the terminal's location information; that is, the more accurate the location information of the terminal determined by the second device based on that information unit. Therefore, the predefined rules may include determining the top N information units with the largest amplitude or power information from the first measurement information to identify the information units that can accurately determine the terminal's location information.

[0138] In some embodiments of this application, the first device may first determine the delay information included in the M second information units, and then determine the N information units with the smallest delay information from the M second information units to determine the N first information units.

[0139] It is understandable that the smaller the latency of an information unit, the higher its correlation with the terminal's location information; that is, the more accurate the location information of the terminal determined by the second device based on that information unit. Therefore, the predefined rules may include determining the top N information units with the smallest latency from the first measurement information to identify the information units that can accurately determine the terminal's location information.

[0140] In some embodiments of this application, the first device may first determine the time delay information included in the M second information units, and then determine the information unit with the smallest time delay information from the M second information units. Then, it may determine the power information or phase information included in the M second information units, and then determine the first N-1 information units with the largest amplitude information or power information from the information units other than the information unit with the smallest time delay information from the M second information units, so as to determine the N first information units.

[0141] In some embodiments of this application, the first device may first determine the power information or phase information included in the M second information units, and determine the information unit with the largest amplitude information or power information from the M second information units. Then, it may determine the time delay information included in the M second information units, and determine the first N-1 information units with the smallest time delay information from the information units other than the information unit with the largest amplitude information or power information from the M second information units, so as to determine the N first information units.

[0142] In some embodiments of this application, when the unit type of the N first information units is a channel sampling point, the above-defined rule may include at least one of the following: determining the top N information units with the largest amplitude information or power information from the first measurement information; determining the top N information units with the smallest delay information from the first measurement information.

[0143] Thus, on the one hand, since the specific content of the predefined rules is specified in this embodiment, the probability that the rules used by the first device to determine and report the N first information units are the same as those used by other devices to determine and report the information units can be increased. Therefore, after the first device determines and reports the N first information units based on the predefined rules, when the second device determines the terminal's location information based on these N first information units and the AI ​​model, the probability of inaccurate terminal location information output by the AI ​​model due to differences between the rules used to determine the N first information units and the rules used to train the AI ​​model can be reduced. Therefore, the second device can accurately determine the terminal's location information. On the other hand, since the first device can determine the N first information units that are highly correlated with the terminal's location information based on the predefined rules, the second device can accurately determine the terminal's location information based on these N first information units. This improves the accuracy of terminal positioning.

[0144] In some embodiments of this application, the above-defined rules are associated with at least one of the following:

[0145] At least one region ID;

[0146] At least one cell list;

[0147] At least one Transmitter / Receiver Point List (TRP list);

[0148] At least one positioning frequency layer;

[0149] At least one cell ID;

[0150] At least one reference signal ID;

[0151] At least one reference signal resource set ID;

[0152] The identifier associated with the AI ​​model.

[0153] In some embodiments of this application, the predefined rule associated with at least one region ID can be understood as: the predefined rule applies to the region associated with the at least one region ID.

[0154] For example, the first device can measure the reference signal or reference signal resource associated with each of the at least one region ID to obtain first measurement information, and determine N first information units from the first measurement information based on predefined rules associated with the at least one region ID.

[0155] In some embodiments of this application, the predefined rule associated with at least one cell list can be understood as: the predefined rule applies to cells in the at least one cell list.

[0156] For example, the first device can measure the reference signal or reference signal resource of each cell in at least one cell list to obtain first measurement information, and determine N first information units from the first measurement information based on predefined rules associated with the at least one cell list.

[0157] In some embodiments of this application, the predefined rule associated with at least one TRP list can be understood as: the predefined rule applies to the TRPs in the at least one TRP list.

[0158] For example, the first device can measure the reference signal or reference signal resource contained in each TRP in at least one TRP list to obtain first measurement information, and determine N first information units from the first measurement information based on predefined rules associated with the at least one TRP list.

[0159] In some embodiments of this application, the predefined rule associated with at least one positioning frequency layer can be understood as: the predefined rule applies to reference signals or reference information resources in at least one positioning frequency layer.

[0160] For example, the first device can measure the reference signal or reference signal resource contained in each of the at least one positioning frequency layer to obtain first measurement information, and determine N first information units from the first measurement information based on predefined rules associated with the at least one positioning frequency layer.

[0161] In some embodiments of this application, the predefined rule associated with at least one cell ID can be understood as: the predefined rule applies to cells associated with at least one cell ID.

[0162] For example, the first device can measure the reference signal or reference signal resource of the cell associated with each cell ID in at least one cell ID to obtain first measurement information, and determine N first information units from the first measurement information based on predefined rules associated with the at least one cell ID.

[0163] In some embodiments of this application, the predefined rule associated with at least one reference signal ID can be understood as: the predefined rule applies to reference signals associated with at least one reference signal ID.

[0164] For example, the first device can measure the reference signal associated with each of the at least one reference signal IDs to obtain first measurement information, and determine N first information units from the first measurement information based on predefined rules associated with the at least one reference signal ID.

[0165] In some embodiments of this application, the predefined rule associated with at least one reference signal resource set ID can be understood as: the predefined rule applies to at least one reference signal resource set associated with a reference signal resource set ID.

[0166] For example, the first device can measure each resource in the reference signal resource set associated with each reference signal resource set ID in at least one reference signal resource set ID to obtain first measurement information, and determine N first information units from the first measurement information based on predefined rules associated with the at least one reference signal resource set ID.

[0167] In some embodiments of this application, the AI ​​model described above can be an AI model of a second device. The identifier associated with the AI ​​model can be a first ID, which can be associated with the identifier of the dataset, the beam antenna configuration on the network side, etc.

[0168] The aforementioned AI model can be used to determine the location information of a terminal. This AI model is associated with a training dataset, which includes multiple third-party measurement information sets. Each third-party measurement information set contains multiple information units, and these information units are determined by a third device from relevant measurement information using predefined rules. The AI ​​model is trained using these multiple third-party measurement information sets; therefore, the AI ​​model is associated with this training dataset. Each third-party device can include at least one of the following: other terminals, other access network devices, or other PRUs. Other terminals can be understood as any terminal different from the aforementioned terminals, other access network devices can be understood as any access network device different from the aforementioned access network devices, and other PRUs can be understood as any PRU different from the aforementioned PRUs.

[0169] Specifically, when the second device uses an AI model to determine the location information of the terminal, the second device can take N first information units as input and output the location information of the terminal.

[0170] In some embodiments of this application, the predefined rule associated with the identifier of the AI ​​model can be understood as: the predefined rule applies to the object indicated by the identifier associated with the AI ​​model.

[0171] In some embodiments of this application, the specific content associated with the above-mentioned predefined rules may be agreed upon by a protocol or indicated by a second device.

[0172] In some embodiments of this application, when the first device reports the second channel measurement information, it reports at least one of the following associated information: region ID, cell ID, TRP ID, reference signal ID, reference signal resource set ID, reference signal resource ID, and model identifier of the AI ​​model.

[0173] In cases where the specific content associated with the predefined rule is indicated by the second device, the first auxiliary information may carry an indication message, which is used to indicate the specific content associated with the defined rule.

[0174] Thus, since the embodiments of this application specify the specific content associated with the predefined rules, the first device and / or the second device can accurately determine whether the first device should determine the first information unit based on the predefined rules according to the specific content.

[0175] Of course, before the first device determines N first information units based on predefined rules, the second device may also indicate relevant information about the predefined rules to the first device so that the first device can determine the predefined rules and / or determine how to use the predefined rules. Examples will be given below.

[0176] In some embodiments of this application, as shown in FIG2 and FIG3, prior to step 101 above, the information reporting method provided in the embodiments of this application may further include the following step 201.

[0177] Step 201: The first device receives first auxiliary information from the second device.

[0178] In some embodiments of this application, the second device described above is a Location Management Function (LMF) network element.

[0179] Of course, the second device can also be other network elements. This application embodiment does not limit this, and those skilled in the art can choose according to their needs.

[0180] Thus, since the specific devices included in the first device are specified in this application embodiment, the specific devices can be configured so that the first device can receive first auxiliary information from the specific devices. In this way, the first device can learn about the relevant information of the predefined rules. Therefore, the first device can determine N first information units from the first measurement information based on the predefined rules and report the second measurement information including the N first information units to the second device, so that the second device can accurately determine the location information of the terminal.

[0181] In this embodiment of the application, the first auxiliary information mentioned above is information related to predefined rules.

[0182] The aforementioned relevant information may include at least one of the following: whether the first information unit is determined based on predefined rules, the rule content of the predefined rules, and the unit type of the first information unit. The unit type may include at least one of the following: channel sampling point, channel path.

[0183] In some embodiments of this application, when the first device is at least one of a terminal and a PRU, the first device can receive first auxiliary information from the second device through an access network device. When the first device is an access network device, the first device can directly receive the first auxiliary information from the second device.

[0184] In some embodiments of this application, when the first device is at least one of a terminal and a PRU, the first device may receive LTE Positioning Protocol (LPP) Request Location Information from the second device, which carries the first auxiliary information.

[0185] In some embodiments of this application, when the first device is an access network device, the first device can receive a New Radio Positioning Protocol a (NRPPa) Measurement Request from the second device, which carries the first auxiliary information.

[0186] Thus, since the first device can receive the first auxiliary information from the second device, the first device can accurately obtain the relevant information of the predefined rules. Therefore, the first device can accurately determine N first information units from the first measurement information based on the predefined rules, and report the second measurement information including the N first information units to the second device, so that the second device can accurately determine the location information of the terminal.

[0187] In some embodiments of this application, prior to step 101 above, the information reporting method provided in the embodiments of this application may further include the following step 200.

[0188] Step 200: The first device reports the eighth instruction information to the second device.

[0189] In this embodiment of the application, the eighth indication information is used to indicate at least one of the following:

[0190] The first device supports the following information unit types:

[0191] The components of the measurement information supported by the first device;

[0192] The maximum number of information units that the first device can support reporting;

[0193] The first device supports the rules for defining information units.

[0194] In some embodiments of this application, the eighth indication information described above is used to determine the first auxiliary information.

[0195] It is understood that the second device can learn, based on the eighth instruction information, at least one of the following: the unit type of the information unit supported by the first device, the components of the measurement information supported by the first device, the maximum number of information units that the first device supports reporting, and the rules for determining information units supported by the first device. Thus, the second device can determine the predefined rules supported by the first device, so that the first device can determine the first information unit based on the predefined rules.

[0196] Thus, since the first device can indicate to the second device through the eighth indication information at least one of the following: the unit type of the information unit supported by the first device, the components of the measurement information supported by the first device, the maximum number of information units that the first device can report, and the rules for determining the information unit supported by the first device, the second device can accurately determine the predefined rules supported by the first device in subsequent steps to ensure that the first device can determine the first information unit based on the predefined rules. Therefore, the situation where the first device cannot determine the first information unit based on the predefined rules can be reduced.

[0197] In some embodiments of this application, the first auxiliary information includes first indication information, which is used to indicate at least one of the following:

[0198] Whether the first information unit is determined based on predefined rules;

[0199] Predefined rules.

[0200] Where the predefined rule is agreed upon by the protocol or configured by other devices or the second device, the first indication information can be used to indicate whether the first information unit is determined based on the predefined rule. It can be understood that if the first device already knows the predefined rule, the first indication information may only indicate whether the first information unit is determined based on the predefined rule; or, the second device may only indicate whether the first device determines the first information unit based on the predefined rule, but the specific rule content depends on the implementation of the first device.

[0201] Here, the first indication information can use one bit to indicate whether the first information unit is determined based on a predefined rule. For example, if the value of this one bit is 0, the first indication information indicates that the first information unit is not determined based on the predefined rule; if the value of this one bit is 1, the first indication information indicates that the first information unit is determined based on the predefined rule. Alternatively, the first indication information can indicate whether the first information unit is determined based on a predefined rule by indicating whether it indicates a predefined rule. For example, if the first indication information indicates a predefined rule, it also indicates that the first information unit is determined based on the predefined rule; if the first indication information does not indicate a predefined rule, it indicates that the first information unit is not determined based on the predefined rule.

[0202] In cases where the predefined rule is configured by another device or a second device, the first indication information can be used to indicate the predefined rule. It is understood that if the first device is not yet aware of the predefined rule, the first indication information can indicate the predefined rule so that the first device can become aware of it.

[0203] In some embodiments of this application, when the first indication information indicates that the first information unit is not determined based on predefined rules, the first device can determine the information unit to be reported from the first measurement information according to a preset algorithm in the first device. In this case, the second device cannot make any assumptions about the method by which the first device determines the information unit to be reported.

[0204] Thus, since the first auxiliary information may also include first indication information for indicating whether the first information unit and / or the predefined rule are determined based on the predefined rule, the first device can know the specific content of whether the first information unit and / or the predefined rule are determined based on the predefined rule, so as to report the information unit for determining the location information of the terminal according to the instructions of the second device.

[0205] In some embodiments of this application, the first auxiliary information further includes second indication information; wherein the second indication information is used to indicate at least one of the following:

[0206] The maximum number of first information units;

[0207] The number of first information units;

[0208] The maximum number of information units other than the one with the smallest time delay information in the first measurement information among the N first information units;

[0209] The maximum number of information units other than the one with the largest amplitude or power information in the first measurement information among the N first information units;

[0210] The number of information units among N first information units, excluding the information unit with the smallest time delay information in the first measurement information;

[0211] The number of information units other than the one with the largest amplitude or power information in the first measurement information among the N first information units.

[0212] In some embodiments of this application, the maximum number of the first information units can be understood as the maximum number of first information units that the measurement information reported by the first device to the second device (e.g., the second measurement information in the embodiments below) may include, or it can be understood as the maximum number of first information units that the measurement information associated with the first reference signal (e.g., the second measurement information in the embodiments below) may include, or the second device supports the maximum number of first information units reported by the first device. Wherein, the number of first information units reported by the first device should be less than or equal to the maximum number of first information units.

[0213] In some examples, when the unit type of the first information unit is a channel sampling point, the maximum number of the first information units may include at least one of the following: 8, 16, 24, 32, 40, 48, 64, 128, 256.

[0214] In other examples, when the cell type of the first information cell is a channel path, the maximum number of the first information cells may include at least one of the following: 8, 9, 16, 17, 32, 33, 64, 65.

[0215] In some embodiments of this application, the number of the first information units can be understood as the number of first information units reported by the first device to the second device, for example, N. It is understood that the number of first information units reported by the first device should be equal to the number of first information units.

[0216] In some examples, when the cell type of the first information cell is a channel path, the number of the first information cells may include at least one of the following: 8, 16, 24, 32, 40, 48, 64, 128, 256.

[0217] In other examples, when the unit type of the first information unit is a channel path, the number of the first information units may include at least one of the following: 8, 9, 16, 17, 32, 33, 64, 65.

[0218] In some cases, the first device can recommend a certain number of first information units to the second device. For example, the first device can learn about the channel environment by measuring a reference signal and recommend a certain number of first information units to be reported to the second device based on the channel environment. This allows the second device to determine the number indicated by the second indication information based on the recommended number of first information units, thereby reducing reporting overhead or improving positioning accuracy.

[0219] Thus, since the first auxiliary information may also include the second instruction information, the first device can use the second instruction information to know the relevant number of the first information units when determining the first information units based on predefined rules. Therefore, it can avoid the situation where the first device determines too many or too few first information units.

[0220] In some embodiments of this application, when the unit type of the N first information units is a channel path and the maximum number of the first information units or the number of the first information units is even, the predefined rules may include at least one of the following: determining the top N information units with the largest amplitude information or power information from the first measurement information; determining the top N information units with the smallest delay information from the first measurement information.

[0221] In some embodiments of this application, when the unit type of the N first information units is a channel path and the maximum number of first information units or the number of first information units is odd, the predefined rules may include at least one of the following: determining the top N information units with the largest amplitude information or power information from the first measurement information; determining the top N information units with the smallest delay information from the first measurement information; determining the information unit with the smallest delay information from the first measurement information, and the top N-1 information units with the largest amplitude information or power information other than the information unit with the smallest delay information; determining the information unit with the largest amplitude information or power information from the N first measurement information, and the top N-1 information units with the smallest delay information other than the information unit with the largest amplitude information or power information.

[0222] In some embodiments of this application, the first auxiliary information further includes third indication information, which is used to indicate the unit type of the N first information units; wherein the unit type includes at least one of the following: channel sampling point, channel path.

[0223] It is understandable that, in this example, the cell type of the N first information units is explicitly indicated by the second device.

[0224] Thus, since the first auxiliary information may also include third instruction information, the first device can learn the unit type of the information unit that the second device requires to be reported by the first device through the third instruction information. Therefore, the first device can report the information unit of the unit type required by the second device, so that the second device can accurately determine the location information of the terminal based on the information unit of the required unit type.

[0225] In some embodiments of this application, when the third indication information indicates that the cell type of N first information cells includes channel sampling points, the predefined rule includes at least one of the following:

[0226] From the first measurement information, determine the top N information units with the largest amplitude or power information;

[0227] The first N information units with the smallest time delay information are determined from the first measurement information.

[0228] Thus, since this application embodiment specifies the specific content of the predefined rules when the unit type of the information unit reported by the first device in the second device requires the first device to include channel sampling points, the first device can determine N first information units that are highly correlated with the location information of the terminal based on the predefined rules, so that the second device can accurately determine the location information of the terminal.

[0229] Of course, the unit type of the N first information units can also be implicitly indicated by the second device.

[0230] In some embodiments of this application, when the second indication information is used to indicate the maximum number of first information units to be reported, the unit type of the N first information units is determined by the maximum number of first information units to be reported.

[0231] In some examples, when the second indication information indicates that the maximum number of first information units to be reported is even, the unit type of the N first information units can be channel sampling points.

[0232] In other examples, where the second indication information indicates that the maximum number of first information units to be reported is odd, the unit type of the N first information units can be a channel path.

[0233] In some other examples, where the second indication information indicates that the maximum number of reported first information units is greater than or equal to the first threshold, the unit type of the N first information units can be channel sampling points.

[0234] In some other examples, where the second indication information indicates that the maximum number of reported first information units is less than or equal to the second threshold, the unit type of the N first information units can be a channel path.

[0235] In some embodiments of this application, when the second indication information is used to indicate the number of first information units reported, the unit type of the N first information units is determined by the number of first information units reported.

[0236] In some examples, when the number of first information units reported as indicated by the second indication information is even, the unit type of the N first information units can be channel sampling points.

[0237] In other examples, when the second indication information indicates that the number of reported first information units is odd, the unit type of the N first information units can be a channel path.

[0238] In some examples, when the second indication information indicates that the number of reported first information units is greater than or equal to the third threshold, the unit type of the N first information units can be channel sampling points.

[0239] In some other examples, when the second indication information indicates that the number of reported first information units is less than or equal to the fourth threshold, the unit type of the N first information units can be a channel path.

[0240] It should be noted that the unit type of the N first information units can be indicated by other implicit indication methods, which are not limited in this embodiment of the application.

[0241] In some embodiments of this application, the unit type of the above-mentioned N first information units is determined based on the bandwidth of the first reference signal or the number of physical resource blocks (PRBs) or resource blocks (RBs); wherein, the unit type includes at least one of the following: channel sampling point, channel path.

[0242] It is understandable that, due to the different power dispersion of the channel path under different bandwidths, the power dispersion or power leakage degree of the time-domain channel response detected by the receiver is different under different numbers of PRBs or RBs. This may lead to different selection of the first information unit type by the same device under different bandwidths, different numbers of PRBs, or different numbers of RBs. Therefore, the unit type of N first information units can be determined by the bandwidth of the first reference signal, the number of physical resource blocks (PRBs), or the number of resource blocks (RBs) to avoid the above-mentioned problems.

[0243] Thus, the unit type of the N first information units is determined based on the bandwidth of the first reference signal, the number of physical resource blocks (PRBs), or the number of resource blocks (RBs). This further reduces the possibility that the first device may choose different unit types for the first information units under different bandwidths. Therefore, it increases the probability that the rules (i.e., predefined rules) used by the first device to determine and report the N first information units are the same as those used by other devices to determine and report the information units. In this way, after the first device determines and reports the N first information units based on the predefined rules, when the second device determines the location information of the terminal based on the N first information units and the AI ​​model, it reduces the probability that the location information of the terminal output by the AI ​​model will be inaccurate due to the difference between the rules used to determine the N first information units and the rules used to determine the information units used to train the AI ​​model. This improves the accuracy of the location information of the terminal determined by the second device.

[0244] In some embodiments of this application, the unit types of the above-mentioned N first information units satisfy at least one of the following:

[0245] When the bandwidth of the first reference signal is greater than or equal to the first threshold, the cell type of the N first information cells is the channel path;

[0246] When the bandwidth of the first reference signal is less than or equal to the second threshold, the cell type of the N first information cells is either a channel sampling point or a channel path;

[0247] When the number of PRBs in the first reference signal is greater than or equal to the third threshold, the cell type of the N first information cells is a channel path;

[0248] When the number of PRBs of the first reference signal is less than or equal to the fourth threshold, the cell type of the N first information cells is either a channel sampling point or a channel path.

[0249] When the number of RBs in the first reference signal is greater than or equal to the fifth threshold, the cell type of the N first information cells is a channel path;

[0250] When the number of RBs in the first reference signal is less than or equal to the sixth threshold, the cell type of the N first information cells is either a channel sampling point or a channel path.

[0251] In some embodiments of this application, the first threshold, second threshold, third threshold, fourth threshold, fifth threshold, and sixth threshold may be configured by the second device, agreed upon by a protocol, or determined by the first device.

[0252] In this embodiment, since the power dispersion of the channel path is smaller when the bandwidth, PRB, or RB of the first reference signal is larger than when the bandwidth, PRB, or RB of the first reference signal is smaller, the possibility of inconsistency in the channel paths extracted by different algorithms and different devices is lower. Therefore, a first threshold, a third threshold, and a fifth threshold can be set. When the bandwidth of the first reference signal is greater than or equal to the first threshold, the unit type of N first information units is determined as the channel path, and / or when the number of PRBs of the first reference signal is greater than or equal to the third threshold, the unit type of N first information units is determined as the channel path, and / or when the number of RBs of the first reference signal is greater than or equal to the fifth threshold, the unit type of N first information units is determined as the channel path, so as to avoid inconsistency in the extracted channel paths.

[0253] For example, Figure 4 shows a power diagram of different information units when the bandwidth, PRB, or RB of the first reference signal is large. As shown in Figure 4, when the bandwidth, PRB, or RB of the first reference signal is large, the power dispersion of the channel path is small. Therefore, the unit type of the N first information units can be determined as the channel path to avoid inconsistencies in the channel paths extracted by different algorithms and different devices.

[0254] In this embodiment, since the power dispersion of the channel path is large when the bandwidth, PRB, or RB of the first reference signal is small, the possibility of inconsistency in the channel paths extracted by different algorithms and devices is high. Therefore, a second threshold, a fourth threshold, and a sixth threshold can be set. This allows the cell types of N first information units to be determined as channel sampling points when the bandwidth of the first reference signal is less than or equal to the second threshold, thereby avoiding the possibility of inconsistency in the extracted channel paths. Alternatively, the cell types of N first information units can be determined as channel paths, and the channel paths can be determined based on predefined rules to avoid the possibility of inconsistency in the extracted channel paths. Or, this can be done by adjusting the number of PRBs in the first reference signal. If the number of RBs in the first reference signal is less than or equal to the fourth threshold, the cell types of the N first information units are determined as channel sampling points to avoid the possibility of inconsistency in the extracted channel paths. Alternatively, the cell types of the N first information units are determined as channel paths, and the channel paths are determined based on predefined rules to avoid the possibility of inconsistency in the extracted channel paths. Or, if the number of RBs in the first reference signal is less than or equal to the sixth threshold, the cell types of the N first information units are determined as channel sampling points to avoid the possibility of inconsistency in the extracted channel paths. Alternatively, the cell types of the N first information units are determined as channel paths, and the channel paths are determined based on predefined rules to avoid the possibility of inconsistency in the extracted channel paths.

[0255] For example, Figure 5 illustrates the power distribution of different information units when the bandwidth, PRB, or RB of the first reference signal is small. As shown in Figure 5, when the bandwidth, PRB, or RB of the first reference signal is small, the power dispersion of the channel path is significant. Therefore, the unit types of the N first information units can be determined as channel sampling points to avoid the possibility of inconsistencies in the extracted channel paths. Alternatively, the unit types of the N first information units can be determined as channel paths, and the channel paths can be determined based on predefined rules to avoid the possibility of inconsistencies in the extracted channel paths.

[0256] Thus, since the cell types of the N first information cells are associated with the bandwidth / PRB / RB of the first reference signal, the inconsistency between the determined information cells and those determined by other devices due to power dispersion can be reduced, thereby enabling the second device to accurately determine the location information of the terminal.

[0257] In some embodiments of this application, the first device may also determine N first information units from the first measurement information based on predefined rules and other parameters, as illustrated below.

[0258] In some embodiments of this application, referring to FIG2 and FIG6, before step 101 above, the information reporting method provided in the embodiments of this application may further include the following step 202, and the above step 101 may be implemented by the following step 101a.

[0259] Step 202: The first device receives the fourth instruction information from the second device.

[0260] It should be noted that, when the first device performs step 201, the order in which the first device performs steps 201 and 202 is not limited in the embodiments of this application. In one example, the first device may perform step 201 first and then step 202; in another example, the first device may perform step 202 first and then step 201; in yet another example, the first device may perform step 202 simultaneously with step 201.

[0261] In this embodiment of the application, the fourth indication information is used to indicate the time range corresponding to the N first information units.

[0262] In some embodiments of this application, the time range corresponding to the above-mentioned N first information units can be understood as: the time range in which the time delay information of the N first information units should be located.

[0263] In some embodiments of this application, the above time range includes at least one of the following: start time, end time, and duration.

[0264] Step 101a: The first device determines N first information units from the first measurement information based on predefined rules and time range.

[0265] In some embodiments of this application, the first device may first determine multiple information units from the first measurement information based on predefined rules, and then determine N first information units from the multiple information units based on a time range; or, the first device may first determine multiple information units from the first measurement information based on a time range, and then determine N first information units from the multiple information units based on predefined rules.

[0266] The first device can determine the time unit within the time range where the delay information is located.

[0267] Thus, since the first device can also receive the fourth instruction information to know the time range corresponding to the information unit required by the second device, the first device can further filter out a smaller number of first information units that meet the requirements of the second device. Therefore, while reducing the amount of information reported, the second device can accurately determine the location information of the terminal.

[0268] In some embodiments of this application, referring to FIG2 and FIG7, before step 101 above, the information reporting method provided by the embodiments of this application may further include step 203 below, and step 101 above can be specifically implemented by step 101b below.

[0269] Step 203: The first device receives the fifth instruction information from the second device.

[0270] It should be noted that, when the first device performs step 202, the order in which the first device performs steps 202 and 203 is not limited in this embodiment. In one example, the first device may perform step 202 first and then step 203; in another example, the first device may perform step 203 first and then step 202; in yet another example, the first device may perform step 203 simultaneously with step 202.

[0271] In this embodiment of the application, the fifth indication information is used to indicate the measurement parameters corresponding to the N first information units.

[0272] In some embodiments of this application, the above measurement parameters include at least one of the following:

[0273] The timing granularity factor corresponding to N first information units;

[0274] The sampling period corresponding to N first information units;

[0275] The window size for the Inverse Fast Fourier Transform (IFFT) corresponding to N first information units.

[0276] Where the unit type of the N first information units is a channel sampling point, the measurement parameters include at least one of the following:

[0277] The timing granularity factor corresponding to N first information units;

[0278] The sampling period corresponding to N first information units;

[0279] The size of the IFFT window corresponding to N first information units.

[0280] When the unit type of N first information units is a channel path, the above measurement parameters include timing granularity factors corresponding to the N channel paths.

[0281] In some embodiments of this application, the timing granularity factor described above can be used to determine the minimum interval between two adjacent channel sampling points being reported.

[0282] In one scenario, if the second device does not configure a timing granularity factor or does not configure a timing granularity factor for the channel sampling point, then the timing granularity factor is determined based on the timing granularity factor configured for path measurement reporting. For example, the timing granularity factor reported based on the channel sampling point is the same as the timing granularity factor reported based on the path measurement; the timing granularity factor reported based on the channel sampling point is X times or 1 / X times the same timing granularity factor reported based on the path measurement; X can be indicated by the second device, and X is a positive number.

[0283] In some embodiments of this application, the above-mentioned sampling period can be the sampling period for the first device to measure the reference signal.

[0284] In some embodiments of this application, the starting position of the IFFT window can be determined based on the downlink timing of the first device, such as a subframe or a slot. Optionally, if the expected time difference of arrival or synchronization error between the neighboring cell and the serving cell of the first device (e.g., a terminal) is greater than a fifth threshold, the measurement of the neighboring cell's signal is not expected in the IFFT window. Optionally, the IFFT window of the neighboring cell of the first device is determined based on the measured i-th channel path or channel sampling point, where i is a positive integer.

[0285] Step 101b: The first device determines N first information units from the first measurement information based on predefined rules and measurement parameters.

[0286] In some embodiments of this application, the first device may first determine multiple information units from the first measurement information based on predefined rules, and then determine N first information units from the multiple information units based on measurement parameters; or, the first device may first determine multiple information units from the first measurement information based on measurement parameters, and then determine N first information units from the multiple information units based on predefined rules.

[0287] The first device can determine the time unit that satisfies the above measurement parameters.

[0288] Thus, since the first device can also receive the fifth instruction information to obtain the measurement parameters corresponding to the information unit required by the second device, the first device can further filter out a smaller number of first information units that meet the requirements of the second device. Therefore, while reducing the amount of information reported, the second device can accurately determine the location information of the terminal.

[0289] Step 102: The first device reports the second measurement information to the second device.

[0290] In this embodiment of the application, the second measurement information includes N first information units, which are used to determine the location information of the terminal.

[0291] In some embodiments of this application, the number of the aforementioned second measurement information can be at least one.

[0292] In some embodiments of this application, the second measurement information described above is associated with at least one of the following:

[0293] At least one reference signal resource ID;

[0294] At least one cell ID;

[0295] At least one reference signal ID;

[0296] At least one TRP ID;

[0297] At least one reference signal resource set ID.

[0298] In some embodiments of this application, the association of the second measurement information with at least one reference signal resource ID can be understood as: the second measurement information is obtained by measuring the reference signal corresponding to the reference signal resource associated with the at least one reference signal resource ID.

[0299] In this system, at least one reference signal resource ID and at least one second measurement information correspond one-to-one, that is, each reference signal resource ID corresponds to one second measurement information, and each second measurement information is obtained by the first device measuring the reference signal resource associated with a reference signal resource ID.

[0300] In some embodiments of this application, the association of the second measurement information with at least one cell ID can be understood as: the second measurement information is obtained by measuring the reference signal of the cell associated with the at least one cell ID.

[0301] In some embodiments of this application, the association of the second measurement information with at least one reference signal ID can be understood as: the second measurement information is obtained by measuring the reference signal associated with at least one reference signal ID.

[0302] In this system, at least one reference signal ID and at least one second measurement information correspond one-to-one, that is, each reference signal ID corresponds to one second measurement information, and each second measurement information is obtained by the first device measuring the reference signal associated with a reference signal ID.

[0303] In some embodiments of this application, the second measurement information associated with at least one TRP ID can be understood as: the second measurement information is obtained by measuring the reference signal sent by the TRP associated with at least one TRP ID.

[0304] In some embodiments of this application, the association of the second measurement information with at least one reference signal resource set ID can be understood as: the second measurement information is obtained by measuring the reference signal corresponding to the resource associated with at least one reference signal resource set ID.

[0305] Thus, since the specific content associated with the second measurement information is specified in the embodiments of this application, the second device can accurately know the specific content associated with the second measurement information after the first device reports the second measurement information.

[0306] In some embodiments of this application, when the unit types of the N first information units include channel sampling points and channel paths, the second measurement information may also carry N tenth indication information, each of which is used to indicate the unit type of a first information unit.

[0307] In some embodiments of this application, the aforementioned second measurement information is specifically used to perform AI positioning on the terminal to determine the terminal's location information.

[0308] In some embodiments of this application, the aforementioned second measurement information is also used to train an AI model in the second device for AI positioning of the terminal.

[0309] In some embodiments of this application, when the first device is at least one of a terminal and a PRU, the first device may receive Location Information provided by the Long Term Evolution Positioning Protocol (LPP) from the second device, which carries the second measurement information.

[0310] In some embodiments of this application, when the first device is an access network device, the first device can receive a New Radio Positioning Protocol a (NRPPa) Measurement Response from the second device, which carries the second measurement information.

[0311] This application provides an information reporting method. A first device can determine N first information units from first measurement information associated with a first reference signal based on predefined rules. The first reference signal is used to locate a terminal, and N is a positive integer. The first device can then report second measurement information including the N first information units to a second device. This second measurement information is used to determine the terminal's location information, allowing the second device to determine the terminal's location based on the second measurement information. Since the predefined rules are predetermined, other devices can also obtain these predefined rules when training the second device's AI model and determine the information units to be reported from the measurement information based on these predefined rules. This ensures that the determination rules for each information unit in the training dataset associated with the second device's AI model match the predefined rules (e.g., are the same, have high correlation, or have low difference). In this way, after the first device determines and reports N first information units based on predefined rules, when the second device determines the terminal's location information based on these N first information units and the AI ​​model, the rules for determining and reporting the N first information units by the first device (i.e., the predefined rules) match (e.g., are the same, have a high correlation, or have a small difference) with the rules for determining information units in the training dataset associated with the AI ​​model of the second device. Therefore, the probability of inaccurate terminal location information output by the AI ​​model due to the mismatch between the rules for determining the N first information units by the first device and the rules for determining information units in the training dataset associated with the AI ​​model can be reduced. This can improve the accuracy of the terminal's location information determined by the second device, thereby improving the accuracy of terminal positioning.

[0312] Furthermore, when the unit type of the N first information units is channel sampling points, on the one hand, since the unit type of the reported first information units is not channel path, it can avoid the inaccuracy of the location information determined by the LMF network element due to the difference between the way the first device determines the channel path and the way other devices determine the channel path; on the other hand, since the first device determines the N first information units from the first measurement information based on predefined rules, it can reduce the probability of the terminal location information output by the AI ​​model being inaccurate due to the mismatch between the rules of the first device for determining the N first information units and the rules for determining the information units of the training dataset associated with the AI ​​model, thereby improving the accuracy of the terminal location information determined by the second device, thus improving the accuracy of terminal positioning.

[0313] In some embodiments of this application, the information reporting method provided in this application may further include the following step 301.

[0314] Step 301: The first device reports the ninth instruction information to the second device.

[0315] It should be noted that the order in which the first device executes step 301 and step 102 is not limited in the embodiments of this application. In one example, the first device may execute step 301 first and then step 102. In another example, the first device may execute step 102 first and then step 301. In yet another example, the first device may execute step 102 at the same time as executing step 301.

[0316] In this embodiment of the application, the aforementioned ninth indication information is used to indicate the information quality corresponding to the N first information units.

[0317] In some embodiments of this application, the above-mentioned information quality can be understood as: the quality of the measurement result corresponding to the first information unit.

[0318] In some embodiments of this application, when the first device can perform step 102 while performing step 301, the first device can carry the ninth indication information in the second measurement information, so that the first device can simultaneously report N first information units and the ninth indication information to the second device.

[0319] In some embodiments of this application, the aforementioned ninth indication information may be quality indication information, wherein the minimum threshold value of the range of the quality indication information may be 0, and the maximum threshold value may be 1. The minimum and maximum threshold values ​​may be agreed upon by a protocol.

[0320] In some embodiments of this application, the aforementioned ninth indication information may include at least one indication information. Where the ninth indication information includes one indication information, that one indication information may indicate the information quality corresponding to N first information units. Where the ninth indication information includes at least two indication information, each indication information may indicate the information quality corresponding to at least one first information unit.

[0321] The indication information may further include at least one sub-indication information, each sub-indication information indicating the information quality corresponding to the measurement information of a first information unit. For example, one sub-indication information may be used to indicate the information quality corresponding to the time delay information of a first information unit, another sub-indication information may be used to indicate the information quality corresponding to the power information of a first information unit, and yet another sub-indication information may be used to indicate the information quality corresponding to the phase information of a first information unit.

[0322] In some embodiments of this application, the information quality corresponding to the above-mentioned N first information units is used by the second device to determine the information units used to determine the location information of the terminal.

[0323] Thus, since the first device can also indicate the information quality corresponding to the N first information units to the second device, the second device can determine at least one first information unit with the best information quality from the N first information units based on the information quality corresponding to the N first information units, and use the at least one first information unit to determine the location information of the terminal. Therefore, the accuracy of the determined location information of the terminal can be improved.

[0324] In some embodiments of this application, prior to step 301 above, the information reporting method provided in the embodiments of this application may further include the following step 300.

[0325] Step 300: The first device receives the first configuration information from the second device.

[0326] In this embodiment of the application, the first configuration information is used to configure the granularity of the ninth instruction information.

[0327] In some embodiments of this application, the granularity of the aforementioned ninth indication information may include at least one of the following: 0.1, 0.2, 0.5, 1.

[0328] In this embodiment of the application, the smaller the granularity of the ninth indication information, the greater the overhead of sending the ninth indication information.

[0329] Thus, it can be seen that since the first device can also configure the granularity of the ninth indication information (i.e., the appropriate granularity) according to the first configuration information sent by the second device, so that the first device can report the ninth indication information to the second device according to the appropriate granularity, the overhead of reporting the ninth indication information can be avoided while the ninth indication information can better reflect the information quality corresponding to the N first information units.

[0330] In some embodiments of this application, the information reporting method provided in this application may further include the following step 401.

[0331] Step 401: The first device reports the second auxiliary information to the second device.

[0332] It should be noted that the order in which the first device executes steps 401 and 102 is not limited in the embodiments of this application. In one example, the first device may execute step 401 first and then step 102. In another example, the first device may execute step 102 first and then step 401. In yet another example, the first device may execute step 102 at the same time as executing step 401.

[0333] In this embodiment of the application, the aforementioned second auxiliary information is used to indicate the relevant information of N first information units.

[0334] In some embodiments of this application, when the first device can perform step 102 while performing step 401, the first device can carry second auxiliary information in the second measurement information, so that the first device can simultaneously report N first information units and second auxiliary information to the second device.

[0335] In this embodiment of the application, the second auxiliary information includes at least one of the following: a sixth indication information and a seventh indication information. The sixth indication information is used to indicate whether the N first information units are determined based on predefined rules; the seventh indication information is used to indicate the unit type of the N first information units.

[0336] Thus, since the second auxiliary information may also include a sixth indication information, meaning the first device can also indicate to the second device through the sixth indication information whether the N first information units are determined based on predefined rules, the second device can accurately know whether the N first information units are determined based on predefined rules; and / or, since the second auxiliary information may also include a seventh indication information, meaning the first device can also indicate to the second device through the seventh indication information the unit type of the N first information units, the second device can accurately know the unit type of the N first information units; thus, the second device can accurately determine the method of using the first information units to determine the location information of the terminal, thereby enabling the second device to accurately determine the location information of the terminal.

[0337] In some embodiments of this application, the second auxiliary information described above satisfies at least one of the following:

[0338] If the bandwidth of the first reference signal is greater than or equal to the seventh threshold, the second auxiliary information does not include the seventh indication information;

[0339] If the number of PRBs in the first reference signal is greater than or equal to the eighth threshold, the second auxiliary information does not include the seventh indication information;

[0340] If the number of RBs in the first reference signal is greater than or equal to the ninth threshold, the second auxiliary information does not include the seventh indication information;

[0341] When the bandwidth of the first reference signal is less than or equal to the tenth threshold, the second auxiliary information includes the seventh indication information;

[0342] When the number of PRBs in the first reference signal is less than or equal to the eleventh threshold, the second auxiliary information includes the seventh indication information;

[0343] If the number of RBs in the first reference signal is less than or equal to the twelfth threshold, the second auxiliary information includes the seventh indication information.

[0344] In some embodiments of this application, the aforementioned seventh, eighth, ninth, tenth, eleventh, and twelfth thresholds may be configured by a second device, agreed upon by a protocol, or determined by a first device.

[0345] Thus, since the specific conditions for reporting the seventh instruction information are specified in the embodiments of this application, the first device can accurately determine whether to report the seventh instruction information according to the specific conditions.

[0346] This application provides a positioning method. Figure 8 shows a flowchart of a positioning method provided in this application. As shown in Figure 8, the positioning method provided in this application may include the following steps 501 to 503.

[0347] Step 501: The second device sends the first auxiliary information to the first device.

[0348] In this embodiment of the application, the first auxiliary information mentioned above is information related to predefined rules.

[0349] It should be noted that the description of the second device sending the first auxiliary information to the first device can be found in the specific description in the above embodiments, and will not be repeated here in the embodiments of this application.

[0350] In this embodiment of the application, the above-mentioned predefined rules are used to determine N first information units from the first measurement information, wherein the first measurement information is measurement information associated with the first reference signal, and the first reference signal is used to locate the terminal.

[0351] It should be noted that the explanation of the predefined rules can be found in the specific descriptions in the above embodiments, and will not be repeated here in the embodiments of this application.

[0352] In some embodiments of this application, the first auxiliary information includes first indication information, which is used to indicate at least one of the following:

[0353] Whether the first information unit is determined based on predefined rules;

[0354] Predefined rules.

[0355] Thus, since the first auxiliary information may also include first indication information for indicating whether the first information unit and / or the predefined rule are determined based on the predefined rule, the first device can know the specific content of whether the first information unit and / or the predefined rule are determined based on the predefined rule, so as to report the information unit for determining the location information of the terminal according to the instructions of the second device.

[0356] In some embodiments of this application, the above-defined rules are associated with at least one of the following:

[0357] At least one region ID;

[0358] At least one cell list;

[0359] At least one TRP list;

[0360] At least one positioning frequency layer;

[0361] At least one cell ID;

[0362] At least one reference signal ID;

[0363] At least one reference signal resource set ID;

[0364] The identifier associated with the AI ​​model.

[0365] Thus, since the embodiments of this application specify the specific content associated with the predefined rules, the first device and / or the second device can accurately determine whether the first device should determine the first information unit based on the predefined rules according to the specific content.

[0366] In some embodiments of this application, the first auxiliary information further includes second indication information, which is used to indicate at least one of the following:

[0367] The maximum number of first information units;

[0368] The number of first information units;

[0369] The maximum number of information units other than the one with the smallest time delay information in the first measurement information among the N first information units;

[0370] The maximum number of information units other than the one with the largest amplitude or power information in the first measurement information among the N first information units;

[0371] The number of information units among N first information units, excluding the information unit with the smallest time delay information in the first measurement information;

[0372] The number of information units other than the one with the largest amplitude or power information in the first measurement information among the N first information units.

[0373] Thus, since the first auxiliary information may also include the second instruction information, the first device can obtain the relevant number of the first information units determined based on the predefined rules through the second instruction information. Therefore, the situation where the first device determines too many or too few first information units can be avoided.

[0374] In some embodiments of this application, where the second indication information is used to indicate at least one of the maximum number of the first information units and the number of the first information units, the positioning method provided in the embodiments of this application may further include the following step 601.

[0375] Step 601: The second device determines the unit type of the N first information units based on at least one of the maximum number of first information units and the number of first information units.

[0376] It should be noted that the order in which the second device executes steps 601 and 501 is not limited in the embodiments of this application; in one example, the second device may execute step 501 first and then step 601; in another example, the second device may execute step 601 first and then step 501.

[0377] In some embodiments of this application, when the second indication information is used to indicate the maximum number of first information units, the second device can determine the unit type of N first information units based on the maximum number of first information units.

[0378] In some examples, when the maximum number of first information units is even, the second device can determine that the unit type of N first information units is a channel sampling point; when the maximum number of first information units is odd, the second device can determine that the unit type of N first information units is a channel path.

[0379] In some embodiments of this application, when the second indication information is used to indicate the number of first information units, the second device can determine the unit type of N first information units based on the number of first information units.

[0380] In some examples, when the number of first information units is even, the second device can determine that the unit type of N first information units is a channel sampling point; when the number of first information units is odd, the second device can determine that the unit type of N first information units is a channel path.

[0381] Thus, since the second device can also determine the unit type of the N first information units based on at least one of the maximum number of the first information units and the number of the first information units, without the need for the first device to indicate, the resources occupied by indicating the unit type of the N first information units can be reduced.

[0382] In some embodiments of this application, the first auxiliary information further includes third indication information, which is used to indicate the unit type of the N first information units; wherein the unit type includes at least one of the following: channel sampling point, channel path.

[0383] Thus, since the first auxiliary information may also include third instruction information, the first device can learn the unit type of the information unit that the second device requires to be reported by the first device through the third instruction information. Therefore, the first device can report the information unit of the unit type required by the second device, so that the second device can accurately determine the location information of the terminal based on the information unit of the required unit type.

[0384] In some embodiments of this application, when the third indication information indicates that the cell type of N first information cells includes channel sampling points, the predefined rule includes at least one of the following:

[0385] From the first measurement information, determine the top N information units with the largest amplitude or power information;

[0386] The first N information units with the smallest time delay information are determined from the first measurement information.

[0387] Thus, since this application embodiment specifies the specific content of the predefined rules when the unit type of the information unit reported by the first device in the second device requires the first device to include channel sampling points, the first device can determine N first information units that are highly correlated with the location information of the terminal based on the predefined rules, so that the second device can accurately determine the location information of the terminal.

[0388] In some embodiments of this application, before step 501 above, the positioning method provided in the embodiments of this application may further include step 602 below, and step 501 above can be specifically implemented by step 501a below.

[0389] Step 602: The second device receives the eighth instruction information from the first device.

[0390] In this embodiment of the application, the eighth indication information is used to indicate at least one of the following:

[0391] The first device supports the following information unit types:

[0392] The components of the measurement information supported by the first device;

[0393] The maximum number of information units that the first device can support reporting;

[0394] The first device supports the rules for defining information units.

[0395] Step 501a: The second device sends the first auxiliary information to the first device according to the eighth instruction information.

[0396] Thus, since the first device can indicate to the second device through the eighth instruction information at least one of the following: the unit type of the information unit supported by the first device, the components of the measurement information supported by the first device, the maximum number of information units that the first device supports reporting, and the rules for determining the information unit supported by the first device, the second device can accurately determine the predefined rules supported by the first device in subsequent steps. This ensures that the first device can determine the first information unit based on the predefined rules, thereby reducing the possibility of the first device being unable to determine the first information unit based on the predefined rules.

[0397] Step 502: The second device receives the second measurement information from the first device.

[0398] In this embodiment of the application, the second measurement information includes N first information units, where N is a positive integer.

[0399] In some embodiments of this application, before step 502 above, the positioning method provided in the embodiments of this application may further include the following step 701.

[0400] Step 701: The second device sends a fourth instruction message to the first device.

[0401] It should be noted that the order in which the first device executes steps 501 and 701 is not limited in the embodiments of this application. In one example, the first device may execute step 501 first and then step 701; in another example, the first device may execute step 701 first and then step 501; in yet another example, the first device may execute step 701 simultaneously with step 501.

[0402] In this embodiment of the application, the fourth indication information is used to indicate the time range corresponding to the N first information units; the time range is used to determine the N first information units.

[0403] In some embodiments of this application, the above time range includes at least one of the following: start time, end time, and duration.

[0404] Thus, since the second device can also send a fourth instruction message to the first device to indicate the time range corresponding to the information unit required by the second device, the first device can further filter out a smaller number of first information units that meet the requirements of the second device. Therefore, while reducing the amount of information reported, the second device can accurately determine the location information of the terminal.

[0405] In some embodiments of this application, before step 502 above, the positioning method provided in the embodiments of this application may further include step 702 below.

[0406] Step 702: The second device sends the fifth instruction information to the first device.

[0407] It should be noted that the order in which the first device executes steps 501 and 702 is not limited in the embodiments of this application. In one example, the first device may execute step 501 first and then step 702; in another example, the first device may execute step 702 first and then step 501; in yet another example, the first device may execute step 702 simultaneously with step 501.

[0408] In this embodiment of the application, the fifth indication information is used to indicate the measurement parameters corresponding to the N first information units; the measurement parameters are used to determine the N first information units.

[0409] In some embodiments of this application, the above measurement parameters include at least one of the following:

[0410] The timing granularity factor corresponding to N first information units;

[0411] The sampling period corresponding to N first information units;

[0412] The size of the IFFT window corresponding to N first information units.

[0413] Thus, since the second device can also send a fifth instruction message to the first device to indicate the measurement parameters corresponding to the information unit required by the second device, the first device can further filter out a smaller number of first information units that meet the requirements of the second device. Therefore, while reducing the amount of information reported, the second device can accurately determine the location information of the terminal.

[0414] In some embodiments of this application, the positioning method provided in this application may further include the following step 703.

[0415] Step 703: The second device receives the ninth instruction information from the first device.

[0416] It should be noted that the order in which the first device executes steps 502 and 703 is not limited in the embodiments of this application. In one example, the first device may execute step 502 first and then step 703; in another example, the first device may execute step 703 first and then step 502; in yet another example, the first device may execute step 703 simultaneously with step 502.

[0417] In this embodiment of the application, the aforementioned ninth indication information is used to indicate the information quality corresponding to the N first information units.

[0418] Thus, since the second device can also obtain the information quality corresponding to the N first information units from the first device, the second device can determine at least one first information unit with the best information quality from the N first information units based on the information quality corresponding to the N first information units, thereby determining at least one first information unit with the highest correlation to the terminal's location information, and using at least one first information unit to determine the terminal's location information. Therefore, the accuracy of the determined terminal's location information can be improved.

[0419] In some embodiments of this application, before step 703 above, the positioning method provided in the embodiments of this application may further include step 704 below.

[0420] Step 704: The second device sends the first configuration information to the first device.

[0421] In this embodiment of the application, the first configuration information is used to configure the granularity of the ninth instruction information.

[0422] Thus, since the second device can also instruct the first device to configure the granularity of the ninth instruction information (i.e., the appropriate granularity), so that the first device can report the ninth instruction information to the second device according to the appropriate granularity, the overhead of reporting the ninth instruction information can be avoided, while the ninth instruction information can better reflect the information quality corresponding to the N first information units.

[0423] In some embodiments of this application, the positioning method provided in this application may further include the following step 705.

[0424] Step 705: The second device receives second auxiliary information from the first device.

[0425] It should be noted that the order in which the first device executes steps 502 and 705 is not limited in the embodiments of this application. In one example, the first device may execute step 502 first and then step 705; in another example, the first device may execute step 705 first and then step 502; in yet another example, the first device may execute step 705 simultaneously with step 502.

[0426] In this embodiment of the application, the aforementioned second auxiliary information is used to indicate the relevant information of N first information units.

[0427] In this embodiment of the application, the second auxiliary information includes at least one of the following: a sixth indication information and a seventh indication information; the sixth indication information is used to indicate whether the N first information units are determined based on predefined rules; the seventh indication information is used to indicate the unit type of the N first information units.

[0428] Thus, since the second auxiliary information may also include a sixth indication information, meaning the first device can also indicate to the second device through the sixth indication information whether the N first information units are determined based on predefined rules, the second device can accurately know whether the N first information units are determined based on predefined rules; and / or, since the second auxiliary information may also include a seventh indication information, meaning the first device can also indicate to the second device through the seventh indication information the unit type of the N first information units, the second device can accurately know the unit type of the N first information units; thus, the second device can accurately determine the method of using the first information units to determine the location information of the terminal, thereby enabling the second device to accurately determine the location information of the terminal.

[0429] Step 503: The second device determines the location information of the terminal based on the second measurement information.

[0430] In some embodiments of this application, the second device can input the second measurement information into the AI ​​model to obtain the terminal's location information output by the AI ​​model. Of course, the second device can also use other methods to determine the terminal's location information, and this application embodiment does not limit this.

[0431] This application provides a positioning method in which a second device can send first auxiliary information to a first device. This first auxiliary information is related to predefined rules. The second device also receives second measurement information from the first device, including N first information units (where N is a positive integer). The second device can then determine the location information of a terminal based on this second measurement information. The predefined rules are used to determine the N first information units from the first measurement information, which is associated with a first reference signal used for locating the terminal. Since the predefined rules are predetermined, other devices can also acquire these rules when training the AI ​​model of the second device and determine the information units to be reported from the measurement information based on these rules. This ensures that the determination rules for each information unit in the training dataset associated with the AI ​​model of the second device match the predefined rules (e.g., are the same, have high correlation, or have small differences). In this way, after the second device instructs the first device on the relevant information of the predefined rules through the first auxiliary information and receives the second measurement information from the first device, when the second device determines the location information of the terminal based on the N first information units in the second measurement information and the AI ​​model, because the rules for determining the reported N first information units (i.e., the predefined rules) of the first device match the rules for determining the information units of the training dataset associated with the AI ​​model of the second device (e.g., they are the same, or have a high correlation, or have a small difference), the probability of the terminal location information output by the AI ​​model being inaccurate due to the mismatch between the rules for determining the N first information units of the first device and the rules for determining the information units of the training dataset associated with the AI ​​model can be reduced. This can improve the accuracy of the terminal location information determined by the second device, thereby improving the accuracy of terminal positioning.

[0432] The following two specific examples illustrate the specific solutions of the positioning method provided in the embodiments of this application.

[0433] Example 1: The first device is a terminal.

[0434] Figure 9 shows a flowchart of the positioning method provided in an embodiment of this application. As shown in Figure 9, the positioning method provided in an embodiment of this application may include the following steps:

[0435] S1. The terminal reports its capabilities to a second device (e.g., an LMF network element), the capabilities of which include a ninth indication information, which indicates at least one of the following: the unit type of information unit supported by the terminal, the components of the measurement information supported by the terminal, the maximum number of information units that the terminal can report, and the rules for determining information units supported by the terminal.

[0436] S2, the LMF network element can send auxiliary information (such as the first auxiliary information in the above embodiment) to the terminal, which can be carried by LPP Request Location Information.

[0437] S3. The terminal can measure the downlink PRS (e.g., the first reference signal in the above embodiment) and obtain the first measurement information, and based on the auxiliary information, determine N first information units from the first measurement information based on predefined rules.

[0438] S4. The terminal can report second measurement information to the LMF network element. The second measurement information includes N first information units. The second measurement information can be carried by LPP Provide Location Information.

[0439] Example 2: The first device is an access network device.

[0440] Figure 10 shows a flowchart of the positioning method provided in an embodiment of this application. As shown in Figure 10, the positioning method provided in an embodiment of this application may include the following steps:

[0441] S5. The access network device (e.g., gNB) reports configuration information to the second device (e.g., LMF network element). The configuration information includes a ninth indication information, which indicates at least one of the following: the unit type of information unit supported by gNB, the components of measurement information supported by gNB, the maximum number of information units that gNB can report, and the rules for determining information units supported by gNB.

[0442] S6. The LMF network element can send auxiliary information (such as the first auxiliary information in the above embodiment) to the gNB. This auxiliary information can be carried by the NRPPa Measurement Request.

[0443] S7 and gNB can measure the uplink PRS (e.g., the first reference signal in the above embodiment) and obtain the first measurement information. Based on auxiliary information and predefined rules, they can determine N first information units from the first measurement information.

[0444] S8 and gNB can report second measurement information to the LMF network element. This second measurement information includes N first information units and can be carried by the NRPPa Measurement Response.

[0445] The information reporting method provided in this application can be executed by an information reporting device. This application uses an information reporting device executing the information reporting method as an example to illustrate the information reporting device provided in this application.

[0446] This application provides an information reporting device. As an example, the information reporting device may be a communication device or a component within a communication device, such as a chip. The communication device may be a terminal, a network-side device, or a server, etc. Exemplarily, the terminal may include, but is not limited to, the type of terminal 11 listed above, and the network-side device may include, but is not limited to, the type of network-side device 12 listed above. This application does not impose specific limitations.

[0447] The information reporting device includes a determining module and a reporting module. These modules can be implemented in software or hardware. When implemented in hardware, the processing module can be implemented by a processor. For example, the processor can include general-purpose processors, special-purpose processors, such as a Central Processing Unit (CPU), microprocessor, Digital Signal Processor (DSP), Artificial Intelligence (AI) processor, Graphics Processing Unit (GPU), Application Specific Integrated Circuit (ASIC), Network Processor (NP), Field Programmable Gate Array (FPGA), or other programmable logic devices, gate circuits, transistors, discrete hardware components, etc. The receiving module and the transmitting module can be implemented by a communication interface, which can include one or more of the following: transceiver, pins, circuits, bus, radio frequency unit, etc.

[0448] Specifically, referring to Figure 11, when the information reporting device is a terminal, a component within a terminal, or a network-side device, the information reporting device 80 includes a determining module 81, used to determine N first information units from first measurement information based on predefined rules. The first measurement information is measurement information associated with a first reference signal, which is used to locate the terminal. N is a positive integer. A reporting module 82 is used to report second measurement information to a second device. The second measurement information includes N first information units and is used to determine the terminal's location information.

[0449] This application provides an information reporting device. Since the predefined rules are predetermined, other devices can also obtain the predefined rules when training the AI ​​model of the second device, and determine the information units to be reported from the measurement information based on the predefined rules. This allows the determination rules of each information unit in the training dataset associated with the AI ​​model of the second device to match the predefined rules (e.g., the same, or highly correlated, or with little difference). In this way, after the information reporting device determines and reports N first information units based on predefined rules, when the second device determines the terminal's location information based on these N first information units and the AI ​​model, the rules used by the information reporting device to determine the reported N first information units (i.e., predefined rules) match (e.g., are the same, have high correlation, or have small differences) with the rules used to determine the information units in the training dataset associated with the AI ​​model of the second device. Therefore, the probability of inaccurate terminal location information output by the AI ​​model due to mismatch between the rules used by the information reporting device to determine the N first information units and the rules used to determine the information units in the training dataset associated with the AI ​​model can be reduced. This improves the accuracy of the terminal's location information determined by the second device, thereby increasing the precision of terminal positioning.

[0450] In one possible implementation, the predefined rule includes at least one of the following: determining the top N information units with the largest amplitude or power information from the first measurement information; determining the top N information units with the smallest delay information from the first measurement information; determining one information unit with the smallest delay information from the first measurement information, and the top N-1 information units with the largest amplitude or power information other than the one with the smallest delay information; determining one information unit with the largest amplitude or power information from N pieces of first measurement information, and the top N-1 information units with the smallest delay information other than the one with the largest amplitude or power information.

[0451] In one possible implementation, the information reporting device 80 provided in this application embodiment may further include: a receiving module. The receiving module is configured to receive first auxiliary information from a second device before the determining module 81 determines N first information units from the first measurement information based on predefined rules. The first auxiliary information is related to predefined rules.

[0458] In one possible implementation, the information reporting device 80 provided in this application embodiment may further include a receiving module. The receiving module is configured to receive fourth indication information from the second device before the reporting module 82 reports the second measurement information to the second device. This fourth indication information indicates the time range corresponding to the N first information units. The determining module 81 is specifically configured to determine the N first information units from the first measurement information based on predefined rules and time ranges; wherein the time range includes at least one of the following: start time, end time, and duration.

[0459] In one possible implementation, the information reporting device 80 provided in this application embodiment may further include a receiving module. The receiving module is configured to receive fifth indication information from the second device before the reporting module 82 reports the second measurement information to the second device. This fifth indication information indicates the measurement parameters corresponding to the N first information units.

[0465] In one possible implementation, the reporting module 82 is further configured to report a ninth indication information to the second device, the ninth indication information being used to indicate the information quality corresponding to the N first information units.

[0466] In one possible implementation, the information reporting device 80 provided in this application embodiment may further include a receiving module. The receiving module is configured to receive first configuration information from the second device before the reporting module 82 reports the ninth indication information to the second device.

[0475] The positioning device includes a transmitting module, a receiving module, and a determining module. These modules can be implemented in software or hardware. When implemented in hardware, the processing module can be implemented by a processor. For example, the processor can include general-purpose processors, special-purpose processors, such as a Central Processing Unit (CPU), microprocessor, Digital Signal Processor (DSP), Artificial Intelligence (AI) processor, Graphics Processing Unit (GPU), Application Specific Integrated Circuit (ASIC), Network Processor (NP), Field Programmable Gate Array (FPGA), or other programmable logic devices, gate circuits, transistors, discrete hardware components, etc. The receiving and transmitting modules can be implemented by a communication interface, which can include one or more of the following: transceiver, pins, circuits, bus, radio frequency unit, etc.
