The base station is not limited to a specific technical term, and it should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0093] In order to better understand the embodiments of the present application, the artificial intelligence (AI) is described.

[0094] Artificial intelligence (AI) has been widely applied in various fields. Integrating artificial intelligence into wireless communication network and significantly improving technical indicators such as throughput, delay and user capacity are important tasks for future wireless communication network. AI module has various implementation manners, such as neural network, decision tree, support vector machine, Bayesian classifier, etc. The present application takes neural network as an example for description, but does not limit the specific type of AI module.

[0095] A schematic diagram of a neural network can be shown in FIG. 2. The neural network is composed of neurons, and a schematic diagram of a neuron is shown in FIG. 3. Wherein, a1, a2, … aK are inputs, w is a weight (multiplicative coefficient), b is a bias (additive coefficient), and σ(.) is an activation function. Common activation functions include Sigmoid, tanh, rectified linear unit (ReLU), etc.

[0096] The parameters of the neural network are optimized by gradient optimization algorithm. Gradient optimization algorithm is a class of algorithms for minimizing or maximizing objective function (sometimes also called loss function), and the objective function is often a mathematical combination of model parameters and data. For example, given data X and its corresponding label Y, we construct a neural network model f(.), after having the model, we can get the predicted output f(x) according to the input x, and can calculate the gap between the predicted value and the true value (f(x)-Y), which is the loss function. Our goal is to find the appropriate W, b to make the value of the above loss function reach the minimum, the smaller the loss value, the closer our model is to the true situation.

[0097] The common optimization algorithm is based on error back propagation (BP) algorithm. The basic idea of BP algorithm is that the learning process consists of two processes of forward propagation of signals and backward propagation of errors. When forward propagation, the input sample is transmitted from the input layer to the output layer through each hidden layer. If the actual output of the output layer does not match the expected output, the backward propagation of errors is entered. The error back propagation is to transmit the output error to the input layer through the hidden layer in a certain form, and allocate the error to all units of each layer to obtain the error signal of each unit, which is used as the basis for correcting the weights of each unit. The weight adjustment process of each layer is repeated. The process of continuously adjusting the weights is the learning and training process of the network. This process continues until the output error of the network is reduced to an acceptable level or the preset learning times are reached.

[0098] The common optimization algorithm includes gradient descent, stochastic gradient descent (SGD), mini-batch gradient descent, momentum method, Nesterov (specifically, stochastic gradient descent with momentum), adaptive gradient descent (Adagrad), Adadelta, root mean square prop (RMSprop), adaptive moment estimation (Adam), etc. When the error back propagation, these optimization algorithms obtain the error / loss from the loss function, derive the current neuron, add the learning rate, the previous gradient / derivative / partial derivative, etc. to obtain the gradient, and transmit the gradient to the previous layer.

[0099] In practice, directly training a neural network on a small-scale dataset can cause overfitting, as the size of the real-time collected dataset is small. The neural network can achieve good convergence or inference accuracy on the training set, but the convergence or inference accuracy on the validation set or test set is poor, which is also called the generalization problem of the neural network. In order to improve the generalization ability, a common method is to pre-train the neural network based on a large amount of offline collected data, and then fine-tune the parameters or structure of the pre-trained neural network with real-time collected data to adapt the neural network to the actual environment. If fine-tuning only updates the parameters of the neural network, it can be considered that fine-tuning is a training process based on the parameters of the pre-trained neural network as initialization. The parameters of part of the layers can be frozen in the fine-tuning stage. Generally, the parameters of the layers close to the input end are frozen to retain the coarse-grained features learned from the large-scale dataset, and the parameters of the layers close to the output end are fine-tuned to adapt the network to the fine-grained features of the actual environment. The less the amount of data in the fine-tuning stage, the more layers are frozen, and only a small number of layers close to the output end are fine-tuned. If fine-tuning updates the structure of the neural network, the structure of the last few layers of the neural network can be fine-tuned, such as adding an additional layer before the output layer, adjusting the number of neurons in the last few layers, and the like. After the structure is changed, the parameters of the neural network can be further updated using the above parameter updating method.

[0100] Generalization of a neural network refers to the ability of the neural network to obtain relatively accurate output for data that has not been encountered during the training (also known as learning) process. There are three solutions to the generalization problem caused by changes in factors such as the wireless transmission environment and the hardware implementation of the transceiver (such as the number of antennas, beam pattern, etc.) based on the neural network wireless communication system: 1) The first is to train different neural networks under different conditions (such as different cells, different areas, different motion speeds, and different channel conditions), and each condition corresponds to a set of neural network parameters or structures. The corresponding neural network is selected or activated in different actual environments to ensure the accuracy of inference; 2) The second is to train a neural network based on a mixed data set under multiple conditions, so that the neural network can adapt to multiple conditions to improve the robustness of the neural network to environmental changes and avoid frequent switching; 3) Fine-tuning: A set of data is collected under new conditions, and the parameters or structure of the original neural network are fine-tuned. These three modes have their own advantages and disadvantages: the first scheme performs well under different transmission conditions, but requires storing multiple neural network parameters or structures and switching as needed, which may cause additional signaling overhead, model management complexity, and frequent switching problems; The second scheme is a set of neural network parameters or structures that can be applied to multiple conditions, but cannot achieve optimal performance under each condition; The third scheme can quickly adapt the neural network to various new scenarios, but requires collecting new data and performing neural network model training, and its performance is limited by factors such as the similarity between the pre-training data set and the newly collected data, the size of the new data, etc.

[0101] In machine learning and deep learning, a label (or ground truth label) generally refers to the identification or annotation of the true class or target value of a data sample. The label is used to represent the information that the model should learn and predict given the input data sample, for example: in a classification task, the label indicates which category the data sample belongs to. For example, for image classification, each image sample has a label indicating the class or probability of the object or scene contained in the image, such as "dog" or "cat", or the probability of belonging to "dog" or "cat".

[0102] Label in object detection: The label usually includes position information (bounding box) and class information of the object. Each label identifies an object in the image, including its position and class.

[0103] Label for time series prediction or regression task: The label usually represents a continuous or real-valued target to be predicted. For example, the label in a house price prediction task can be the predicted future house sales price.

[0104] Label in sequence labeling: In natural language processing, labels in sequence labeling tasks are commonly used in tasks such as part-of-speech tagging, named entity recognition, etc., where labels are used to represent the attributes or categories of each word or character in the text sequence.

[0105] Labels are a key component in supervised learning tasks, used to train machine learning models. Models learn patterns and rules through comparison with true labels in order to make predictions or classifications on unseen data. The quality and accuracy of labels are crucial to the performance of the model.

[0106] For better understanding of the embodiments of the present application, the channel path and channel sampling point are described.

[0107] Channel sampling points are observations of the channel obtained with a certain time granularity T, and channel sampling points can also be referred to as time-domain channel sampling points.

[0108] Timing reporting granularity factor k, in the NR protocol, LMF can recommend k value to UE, but which k value to report the time information of channel path (such as Reference Signal Time Difference, RSTD) still depends on UE, but when UE reports the time information, it needs to report the k value associated with the channel path to the network side. For the reporting mode based on channel path, the selection of k value is related to the accuracy of the time information (such as RSTD) reported by the terminal, the larger the k value, the coarser the granularity of the reported time information, the range of k value supported by the current protocol is an integer greater than or equal to 0 and less than or equal to 5, the k value corresponds to the minimum time interval of the reported time information of two channel paths or the timing granularity of the channel path is T = 2 k ×T c , where T c is the basic time unit of NR. For the reporting mode based on channel sampling points, the k value selected by the terminal side may affect the accuracy of the AI model-based positioning function on the LMF side.

[0109] It should be noted that the base station or TRP is also applicable to the scheme on the LMF side.

[0110] The LMF can request the UE to report additional paths in addition to the first path, but the maximum number of additional paths supported by the terminal for reporting depends on the terminal's capability (the terminal will tell the LMF the maximum number of additional paths supported for measurement reporting when reporting the capability), but the actual number of channel paths reported depends on the terminal implementation, but should not exceed the maximum number of channel paths supported by the terminal for reporting. The LMF instructs the terminal to report additional channel paths, and the number of additional channel paths reported by the terminal depends on the terminal implementation, but does not exceed the maximum number of channel paths supported by the terminal capability (such as the current maximum number of channel paths supported is 8) and does not exceed the maximum number of channel paths agreed by the protocol (such as the current maximum number of channel paths supported is 8).

[0111] For the reporting mode based on channel paths, there may be a case where the number of additional channel paths detected by the terminal is less than the maximum number, such as in a wireless environment with fewer scatterers or sparser channel paths, and the accuracy of the channel path estimation algorithm for different UEs also differs. Therefore, only the maximum number of additional channel paths reported by the terminal is limited, and the actual number of channel paths reported depends on the terminal implementation. For the reporting mode based on channel sampling points, the number of channel sampling points detected by the terminal is independent of the wireless environment, but may be related to factors such as the sampling rate of the terminal, the number of Inverse Fast Fourier Transform (IFFT) points, and the signal bandwidth. Therefore, the LMF can specify the actual number of channel sampling points reported by the terminal to improve the performance of AI model-based positioning.

[0112] AI positioning refers to using an AI model to determine the position information of a terminal based on channel measurement quantities (such as the channel delay spectrum, time delay power spectrum, and time-domain channel impulse response (CIR) of at least one TRP associated with the target terminal). For example, the channel measurement quantities are input into the AI model, and the AI model infers the position-related information of the terminal. The position-related information includes at least one of the following: position coordinates, angle-related information (such as Angle of Arrival (AoA) and Angle of Departure (AoD)), time delay-related information (such as Time of Arrival (TOA) and RSTD), distance-related information (such as the distance from the UE to the TRP), and the like.

[0113] Specifically, the channel delay spectrum includes time information of multiple channel paths or channel sampling points, the time delay power spectrum includes time information of multiple channel paths or channel sampling points and power information of multiple channel paths or channel sampling points, and the time-domain CIR includes time information of multiple channel paths or channel sampling points, power information of multiple channel paths or channel sampling points, and phase information of at least one channel path or channel sampling point.

[0114] One method for determining channel sampling points is as follows: at the receiving antenna port a, the first sampling point... The reference symbols (positioning reference signals (PRS) or sounding reference signals (SRS)) received at each subcarrier are given by the following formula:

[0115] Where k = -N / 2, -N / 2+1, ..., N / 2-1;

[0116] 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.

[0117] The measured channel frequency response samples are shown below:

[0118] in, For s k . conjugate.

[0119] Assumption: N FFT >N represents the window size for a single 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.

[0120] Then, the channel frequency response can be expressed as:

[0121] By taking the IFFT of the frequency domain channel response sampling points, the measured channel impulse response (CIR) sampling points are obtained:

[0122] Where d = 0, 1, ..., N FFT -1, and w a [d] is Wa IFFT of [k].

[0123] because The term, τ, indicates that a true channel tap can induce a time-domain (TD) response at a large number of measurement sampling points, exhibiting a large response near the true delay and attenuating for sampling points far from the true delay. For example, τ l =265ns, N=3264, and N FFT The actual channel delay when =4096.

[0124] Note that these time-domain or frequency-domain channel measurement sampling points are directly observable at the receiver or receiver unit. These channel sampling points can be further processed in the following ways.

[0125] 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.

[0126] By retaining only the power information at the antenna port at each sampling grid point, the TD delay power spectrum (TD PDP) is obtained from the (truncated) TD CIR:

[0127] By using N with the maximum power t The sampling point is set to a specific value, and the time-domain delay spectrum (TD DP) is obtained from the TD PDP of the sub-sampling point. The specific value can be a constant, such as 1, or the reference signal received power (RSRP) of the link.

[0128] 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 channel path extraction or estimation algorithm is an estimate of the actual propagation path of the signal in the real environment, including the channel 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 the propagation path.

[0129] In addition, the current protocol supports channel path-based reporting, supporting the reporting of the first path and up to 8 additional paths. This allows the network side to confirm the true direct path from these 9 channel paths, such as selecting the Nth path as the direct path (Line of Sight, LOS). However, there are no constraints on how these channel paths are determined by the protocol, which depends on the terminal implementation.

[0166] In some embodiments, the first device can report the power information of the channel sampling point and / or the phase information of the channel sampling point in the manner of reporting the time information of the channel sampling point.

[0167] In some embodiments, the first device can also obtain at least one of the following by measuring a reference signal:

[0168] The time information of the channel path with the minimum delay, the power information of the channel path with the minimum delay, and the phase information of the channel path with the minimum delay.

[0169] In some embodiments, the measurement unit can comprise a combination of time information, power information, and phase information.

[0170] In some embodiments, the measurement unit can comprise a combination of time information, power information, and phase information.

[0171] In some embodiments, the measurement unit is associated with at least one of:

[0172] The at least one of the following: an identity of at least one reference signal resource, an identity of at least one cell, an identity of at least one reference signal, an identity of at least one TRP, an identity of at least one reference signal resource set.

[0173] In some embodiments, the measurement unit is determined based on at least one of the following: an identity of at least one reference signal resource, an identity of at least one cell, an identity of at least one reference signal, an identity of at least one TRP, an identity of at least one reference signal resource set.

[0174] For example, the measurement unit is associated with an identity of at least one reference signal resource, comprising:

[0175] The measurement unit is obtained by measuring at least one reference signal resource.

[0176] For example, the measurement unit is associated with an identity of at least one cell, comprising:

[0177] The measurement unit is obtained by measuring a reference signal associated with at least one cell.

[0178] For example, the measurement unit is associated with an identity of at least one reference signal, comprising:

[0180] For example, the measurement unit is associated with an identity of at least one TRP, comprising:

[0181] The measurement unit is obtained by measuring a reference signal associated with at least one TRP.

[0182] For example, the measurement unit is associated with an identity of at least one reference signal resource set, comprising:

[0183] The measurement unit is obtained by measuring at least one reference signal resource set.

[0184] For example, the first device measures a reference signal resource to obtain channel information (such as time information, power information, phase information, etc.) between the terminal and a TRP.

[0185] The reference signal described in the embodiments of the present application includes but is not limited to at least one of the following:

[0186] Positioning reference signals (PRS), sounding reference signals (SRS), channel state information reference signals (CSI-RS), synchronization signal blocks (SSB).

[0187] It should be noted that the SSB can also be referred to as a synchronization signal / physical broadcast channel block (SS / PBCH block).

[0188] For example, the first device (such as a terminal) measures a plurality of equally spaced channel sampling points and two channel paths, which can be shown in FIG. 5; wherein the sampling period T is related to the implementation of the first device (such as a terminal) and should be no less than the inverse of the bandwidth, such as when the subcarrier spacing is 30 kHz and the bandwidth is 100 MHz, the sampling period T can be 1 / (30k*4096) seconds.

[0189] For example, the channel measurement quantity measured by the first device (such as a terminal) includes power information and delay information of M equally spaced channel sampling points, assuming that at this time:

[0190] For example, if the timing reporting granularity factor k1 associated with the channel sampling point reported by the first device (such as a terminal) is 4, in this case, the channel sampling point reported by the first device (such as a terminal) can be shown in FIG. 6.

[0191] For example, if the timing reporting granularity factor k1 associated with the channel sampling point reported by the first device (such as a terminal) is 5, in this case, the timing granularity of the channel sampling point reported by the first device (such as a terminal) is 2 5 ×T c= 2T, the channel sampling points reported by the first device (e.g., a terminal) can be as shown in FIG. 7. If the timing granularity factor k1 of the channel sampling points reported by the terminal is 5, the timing granularity of the channel sampling points reported by the terminal is 2T 3 × T c = T / 2.

[0192] In some embodiments, the M channel sampling points can be consecutive channel sampling points. For example, the M channel sampling points are the first M consecutive channel sampling points among the N consecutive channel sampling points. For another example, the M channel sampling points are the last M consecutive channel sampling points among the N consecutive channel sampling points. For another example, the M channel sampling points are the M consecutive channel sampling points located in the middle of the N consecutive channel sampling points. For another example, the M channel sampling points are the M consecutive channel sampling points determined from the N consecutive channel sampling points according to a first rule (e.g., a first rule agreed by a protocol or a first rule indicated by a network side).

[0193] For example, the first rule is to select channel sampling points in a descending order of power, or the first rule is to select channel sampling points in an ascending order of time delay.

[0194] In some embodiments, the M channel sampling points can be non-consecutive channel sampling points. For example, the M channel sampling points are the M consecutive channel sampling points located at odd positions among the N consecutive channel sampling points. For another example, the M channel sampling points are the M consecutive channel sampling points located at even positions among the N consecutive channel sampling points. For another example, the M channel sampling points are the M non-consecutive channel sampling points determined from the N consecutive channel sampling points according to a second rule (e.g., a second rule agreed by a protocol or a second rule indicated by a network side).

[0195] For example, the second rule is to select channel sampling points in a descending order of power, or the second rule is to select channel sampling points in an ascending order of time delay.

[0196] In some embodiments, one measurement unit is associated with one reference signal resource identifier or TRP identifier or cell identifier. The TRP identifier and the reference signal identifier have a one-to-one correspondence; in some cases, the TRP identifier can be replaced by the reference signal identifier; or the TRP can be determined by the reference signal identifier.

[0197] In some embodiments, the S measurement units include a first measurement unit;

[0198] The time information of the first channel sampling point among the N consecutive channel sampling points corresponding to the first measurement unit is associated with the time information of the channel path with the smallest time delay of the first measurement unit; or

[0199] The time information of the first channel sampling point of the N continuous channel sampling points corresponding to the first measurement unit is associated with the time information of the channel path with the minimum time delay of the measurement unit associated with the reference TRP; or,

[0200] The time information of the first channel sampling point of the N continuous channel sampling points corresponding to the first measurement unit is associated with the time information of the channel path with the minimum time delay of the measurement unit associated with the reference cell; or,

[0201] The time information of the first channel sampling point of the X continuous channel sampling points corresponding to the first measurement unit is associated with the time information of the channel path with the minimum time delay of the first measurement unit; or,

[0202] The time information of the first channel sampling point of the X continuous channel sampling points corresponding to the first measurement unit is associated with the time information of the channel path with the minimum time delay of the measurement unit associated with the reference TRP; or,

[0203] The time information of the first channel sampling point of the X continuous channel sampling points corresponding to the first measurement unit is associated with the time information of the channel path with the minimum time delay of the measurement unit associated with the reference cell.

[0204] It should be understood that the first measurement unit can be any one of the S measurement units.

[0205] For example, each measurement unit is processed in the same way, and each N continuous channel sampling point is determined based on the respective first path, and each M channel sampling point is determined.

[0206] For example, each measurement unit is processed in the same way, and each X continuous channel sampling point is determined based on the respective first path, and each M channel sampling point is determined.

[0207] For example, for all measurement units, the time of the N continuous channel sampling points is determined based on the first path of the measurement unit associated with the reference TRP, and the M channel sampling points of each TRP are determined within the time duration of the N continuous channel sampling points.

[0208] For example, for all measurement units, the time of the X continuous channel sampling points is determined based on the first path of the measurement unit associated with the reference TRP, and the M channel sampling points of each TRP are determined within the time duration of the X continuous channel sampling points and within the time duration of the N continuous channel sampling points.

[0209] In some embodiments, the time information of the first channel sampling point in the N consecutive channel sampling points is associated with the time information of the channel path with the smallest delay of the T measurement units; or, the time information of the first channel sampling point in the X consecutive channel sampling points is associated with the time information of the channel path with the smallest delay of the T measurement units.

[0210] In some embodiments, the M channel sampling points of each measurement unit in the T measurement units are determined from the N consecutive channel sampling points, or the M channel sampling points of each measurement unit in the T measurement units are located within the duration of the N consecutive channel sampling points.

[0211] In some embodiments, the T measurement units are a subset of the S measurement units, or the T measurement units are determined from the S measurement units, and the reference signal resources associated with the T measurement units are located in the same OFDM symbol.

[0212] For example, for those measurement units whose associated reference signal resources are carried in the same OFDM symbol, the starting position of the N consecutive channel sampling points is determined based on the channel path with the smallest delay among these measurement units, or the starting position of the X consecutive channel sampling points is determined based on the channel path with the smallest delay among these measurement units.

[0213] For example, as shown in FIG. 8, T = 6, and the time of the first channel sampling point in the N consecutive channel sampling points is determined based on the time of the first path (the channel path with the smallest delay) of TRP2.

[0214] Optionally, T1 measurement units (associated with the same OFDM symbol) are associated with a measurement window, and T2 measurement units (associated with another OFDM symbol) are associated with another measurement window. When reporting each measurement unit, the first device needs to distinguish whether different measurement units are associated with different measurement windows:

[0215] 1) not distinguish;

[0216] 2) distinguish: a) explicit indication: when reporting, the first device adds indication information indicating the measurement window associated with each measurement unit (each measurement unit has an indication); or T1 measurement units are associated with a measurement window (T1 measurement units have only one indication); b) implicit indication: the measurement unit reported by the first device further includes the starting point or the first path (relative to the reference time) of the measurement window associated with each measurement unit; if the same, it is considered that multiple measurement units are associated with the same measurement window; if different, it is considered that they are associated with different measurement windows.

[0217] In some embodiments, each measurement unit further comprises, but is not limited to, at least one of the following:

[0218] time information of the channel path with the minimum delay, power information of the channel path with the minimum delay, phase information of the channel path with the minimum delay, k1, k2, difference between k1 and k2;

[0219] wherein k1 represents a timing reporting granularity factor corresponding to reporting of the channel sampling point, and k2 represents a timing reporting granularity factor corresponding to reporting of the channel path.

[0220] Optionally, k1≥k2.

[0221] In this embodiment, for each measurement unit, the first device simultaneously reports measurement information (such as time information, power information, phase information, etc.) of the channel path with the minimum delay and measurement information (such as time information, power information, phase information, etc.) of M channel sampling points in one measurement unit, and allows the timing reporting granularity factor (k2) corresponding to reporting of the channel path to be less than or equal to the timing reporting granularity factor (k1) corresponding to reporting of the channel sampling point, which is beneficial for the second device to jointly utilize the more refined measurement information of the channel path with the minimum delay and the measurement information of M channel sampling points to improve positioning accuracy.

[0222] In this embodiment, the difference between k1 and k2 is carried in the information of each measurement unit, such as Δ=k2-k1 or Δ=k1-k2, which can reduce the overhead of the first measurement information compared to carrying k1 and k2 in the information of each measurement unit.

[0223] Optionally, the first device can report at least one of the following in a differential manner: time information of the channel path with the minimum delay, power information of the channel path with the minimum delay, phase information of the channel path with the minimum delay.

[0224] Optionally, T1 can be determined based on k1, wherein k1 represents a timing reporting granularity factor corresponding to reporting of the channel sampling point, and T1 represents a timing granularity corresponding to reporting of the channel sampling point.

[0225] In this embodiment, the time of the channel sampling point can be an integer multiple of T1.

[0226] Optionally, T2 can be determined based on k2, wherein k2 represents a timing reporting granularity factor (Timing Reporting Granularity Factor), and T2 represents a timing granularity corresponding to reporting of the channel path.

[0227] In this embodiment, the time of the channel path can be an integer multiple of T2.

[0228] Exemplarily, in the case of k1=4 and k2=2, T1 and T2 can be as shown in FIG. 9, where T c denotes a basic time unit, such as a basic time unit in NR, which can be a second (s).

[0229] In some implementations, T1 can be a basic unit of a channel-sampling-point-based reporting grid, and T2 can be a basic unit of a channel-path-based reporting grid.

[0230] In some embodiments, the various measurement units include all possible supported combination cases as follows:

[0231] time information of M channel sampling points;

[0239] It should be noted that the content included in different measurement units can be the same or different.

[0240] In some implementations, the first device reports time information of the M channel sampling points on one information element (IE), and reports power information of the M channel sampling points on one IE, and the protocol agrees that the time information (such as time) of the first channel sampling point in the M channel sampling points is the time information (such as time) of the channel path with the minimum delay.

[0241] In some implementations, the first device has reported measurement information of W channel sampling points, and the first device sends first indication information to the second device, the first indication information being used to indicate that the first channel sampling point in the M channel sampling points is the i-th channel sampling point in the reported W channel sampling points, such as the i-th channel sampling point in the reported W channel sampling points being the first channel sampling point in the M channel sampling points.

[0242] In some implementations, the second device (such as LMF) has two AI models: the first AI model takes the channel path with the minimum delay associated with multiple reference signal resources or multiple TRPs as the input of the AI model to estimate the position information p1 of the first device (such as a terminal); the second AI model takes the measurement information of the channel sampling points associated with multiple reference signal resources or multiple TRPs as the input of the AI model to estimate the position information p2 of the first device (such as a terminal); after obtaining the two inference results, the second device (such as LMF) can obtain a higher-precision positioning result by weighted combination, selection combination, etc. of the two results, or the second device (such as LMF) judges the accuracy of the positioning result of the AI model through cross-validation, or the second device (such as LMF) judges the effectiveness of the AI model through cross-validation.

[0243] In some implementations, the second device (such as LMF) estimates the position information p1 of the first device (such as a terminal) by a non-AI model positioning method (such as triangular positioning) using the measurement information of the channel path with the minimum delay associated with multiple reference signal resources or multiple TRPs; the second device (such as LMF) estimates the position information p2 of the first device (such as a terminal) by taking the measurement information of the channel sampling points associated with multiple reference signal resources or multiple TRPs as the input of the AI model; after obtaining the two inference results, the second device (such as LMF) can obtain a higher-precision positioning result by weighted combination, selection combination, etc. of the two results, or the second device (such as LMF) judges the accuracy of the positioning result of the AI model through cross-validation, or the second device (such as LMF) judges the effectiveness of the AI model through cross-validation.

[0244] In this embodiment, the value of N can be indicated by the network side, the value of X can be indicated by the protocol or the network side, or the value of X can be determined by the first device based on implementation. For example, the value of X is 1, 2, 3, etc.

[0245] Optionally, the first device can determine the M channel sampling points from the X continuous channel sampling points and the N continuous channel sampling points based on a protocol agreement, or the first device can determine the M channel sampling points from the X continuous channel sampling points and the N continuous channel sampling points based on its own implementation.

[0246] In the embodiment, the first device can determine the M channel sampling points from the X continuous channel sampling points and the N continuous channel sampling points, thereby increasing the flexibility of determining the M channel sampling points and improving the positioning accuracy. For example, the first device considers that the timing error is relatively serious at this time, or considers that the estimation of the channel path with the minimum delay (the first path) is inaccurate, or considers that the channel sampling points before the channel path with the minimum delay (the first path) can still provide useful information for AI positioning, and can expand the range of N (i.e., expand to N+X) to be able to report the measurement information of a plurality of channel sampling points before the channel path with the minimum delay (the first path).

[0247] In some embodiments, the number of channel sampling points contained in each measurement unit is M+Z, allowing the terminal to report the measurement information of Z additional channel sampling points before the M channel sampling points, thereby increasing the flexibility of reporting the measurement information of the channel sampling points and improving the positioning accuracy.

[0248] In some embodiments, the wireless communication method 200 further includes:

Thus, the time of the first channel sampling point in the N consecutive channel sampling points can be determined based on the time of the channel path with the smallest delay, and then the N consecutive channel sampling points can be determined, and the M channel sampling points can be determined from the N consecutive channel sampling points. Alternatively, the time of the first channel sampling point in the X consecutive channel sampling points can be determined based on the time of the channel path with the smallest delay, and then the X consecutive channel sampling points and the N consecutive channel sampling points can be determined, and the M channel sampling points can be determined from the X consecutive channel sampling points and the N consecutive channel sampling points.

[0264] In this embodiment, the values of N corresponding to different measurement units can be the same or different. The values of X corresponding to different measurement units can be the same or different.

[0265] For example, the first information can indicate that the maximum value of N is 64.

[0266] For another example, the first information can indicate that the minimum value of N is 16.

[0267] For further example, the first information can indicate a value range of N, such as the value range of N being {16, 24, 32, 64,}. Optionally, the first device selects a value of N from the value range of N, or the first device selects a value of N from the value range of N based on the indication of the second device.

[0268] For example, the first information can indicate that the maximum value of X is 4.

[0269] For another example, the first information can indicate that the minimum value of X is 1.

[0270] For another example, the first information can indicate a value range of X, such as a value range of X being {1, 2, 3, 4,}. Optionally, the first device selects an X value from the value range of X, or the first device selects an X value from the value range of X based on the indication of the second device.

[0271] Optionally, the first offset value can be positive, or the first offset value can be negative, or the first offset value can be zero. In this embodiment, the time of the first channel sampling point in the N continuous channel sampling points is earlier than the time of the channel path with the minimum time delay, or the time of the first channel sampling point in the N continuous channel sampling points is later than the time of the channel path with the minimum time delay, or the time of the first channel sampling point in the N continuous channel sampling points is equal to the time of the channel path with the minimum time delay. Or, the time of the first channel sampling point in the N continuous channel sampling points is not earlier than the time of the channel path with the minimum time delay, or the time of the first channel sampling point in the N continuous channel sampling points is not later than the time of the channel path with the minimum time delay. Or, there is a first offset value between the time of the first channel sampling point in the X continuous channel sampling points and the time of the channel path with the minimum time delay; wherein the time of the first channel sampling point in the X continuous channel sampling points is earlier than the time of the channel path with the minimum time delay, or the time of the first channel sampling point in the X continuous channel sampling points is later than the time of the channel path with the minimum time delay, or the time of the first channel sampling point in the X continuous channel sampling points is equal to the time of the channel path with the minimum time delay.

[0272] Optionally, if the N continuous channel sampling points are all the channel sampling points in the channel measurement window, or the N continuous channel sampling points can be replaced by the channel measurement window, the first information further indicates at least one of the following:

[0273] The start position of the channel measurement window, the end position of the channel measurement window, and the time length of the channel measurement window.

[0274] Optionally, the reference time is a downlink subframe boundary of a reference TRP, or the reference time is a downlink subframe boundary of a reference cell, or the reference time is a Universal Time Coordinated (UTC) time, or the reference time is configured by a network side, or the reference time is agreed by a protocol.

[0275] Optionally, before S210, the first device receives the first information from the second device.

[0276] In some embodiments, the time of the channel path with the minimum delay is determined based on the following Formula 1:

[0277] wherein j represents the time of the channel path with the minimum delay in association with k1, i represents the time of the channel path with the minimum delay in association with k2, T c represents a basic time unit (e.g., s), k1 represents a timing reporting granularity factor corresponding to reporting of a channel sampling point, and k2 represents a timing reporting granularity factor corresponding to reporting of a channel path.

[0278] In some embodiments, the time of the channel path with the minimum delay is determined based on the following Formula 2:

[0279] wherein j represents the time of the channel path with the minimum delay in association with k1, i represents the time of the channel path with the minimum delay in association with k2, T c represents a basic time unit (e.g., s), k1 represents a timing reporting granularity factor corresponding to reporting of a channel sampling point, and k2 represents a timing reporting granularity factor corresponding to reporting of a channel path.

[0280] In some embodiments, the time of the channel path with the minimum delay is determined based on the following Formula 3:

[0281] wherein j represents the time of the channel path with the minimum delay in association with k1, i represents the time of the channel path with the minimum delay in association with k2, T c represents a basic time unit (e.g., s), k1 represents a timing reporting granularity factor corresponding to reporting of a channel sampling point, and k2 represents a timing reporting granularity factor corresponding to reporting of a channel path.

[0282] Optionally, j can also represent an index of the channel path with the minimum delay in association with k1, and i can also represent an index of the channel path with the minimum delay in association with k2.

[0283] It should be noted that Formula 1 corresponds to rounding down, Formula 2 corresponds to rounding up, and Formula 3 corresponds to rounding.

[0284] In Formulas 1 to 3, by performing the rounding operation, implementation can be simpler.

[0285] For example, the index of the channel path with the minimum delay detected by the first device in the reporting grid at k2=2 is 5, and based on the above formula 1, the index of the channel path with the minimum delay in the reporting grid at k1=4 is 1.25, and the index of the channel path with the minimum delay in the reporting grid at k1=4 is j=1 after rounding down, as shown in FIG. 10.

[0286] It should be noted that the grid index described in the embodiments of the present application can be understood as a time or time index or timing value (Timing value) with a certain time granularity or time interval T.

[0287] In some implementations, the above formula 1 can also not be rounded. For example, the index of the channel path with the minimum delay detected by the first device in the reporting grid at k2=2 is 5, and the index of the channel path with the minimum delay in the reporting grid at k1=4 is 1.25, that is, the index of the channel path with the minimum delay in the reporting grid at k1=4 is j=1.25, as shown in FIG. 11.

[0288] In some embodiments, there is a first offset value between the time of the first channel sampling point in the N continuous channel sampling points and the time of the channel path with the minimum delay.

[0289] In some embodiments, the time of the first channel sampling point in the N continuous channel sampling points is earlier than the time of the channel path with the minimum delay, or the time of the first channel sampling point in the N continuous channel sampling points is later than the time of the channel path with the minimum delay, or the time of the first channel sampling point in the N continuous channel sampling points is equal to the time of the channel path with the minimum delay. Or, the time of the first channel sampling point in the N continuous channel sampling points is not earlier than the time of the channel path with the minimum delay, or the time of the first channel sampling point in the N continuous channel sampling points is not later than the time of the channel path with the minimum delay.

[0290] In the present embodiment, there is a first offset value between the time of the first channel sampling point in the N continuous channel sampling points and the time of the channel path with the minimum delay, so that the time of the first channel sampling point in the N continuous channel sampling points can be determined based on the time of the channel path with the minimum delay, and then the N continuous channel sampling points are determined, and the M channel sampling points are determined from the N continuous channel sampling points.

[0291] In some embodiments, there is a first offset value between the time of the first channel sampling point in the channel measurement window and the time of the channel path with the minimum delay.

[0292] The time of the first channel sampling point in the channel measurement window is earlier than the time of the channel path with the minimum delay, or the time of the first channel sampling point in the channel measurement window is later than the time of the channel path with the minimum delay, or the time of the first channel sampling point in the channel measurement window is equal to the time of the channel path with the minimum delay. Alternatively, the time of the first channel sampling point in the channel measurement window is not earlier than the time of the channel path with the minimum delay, or the time of the first channel sampling point in the channel measurement window is not later than the time of the channel path with the minimum delay.

[0293] For example, when the first offset value is greater than 0, the first channel sampling point in the channel measurement window is later in time than the channel path with the minimum delay; when the first offset value is less than 0, the first channel sampling point in the channel measurement window is earlier in time than the channel path with the minimum delay; and when the first offset value is equal to 0, the first channel sampling point in the channel measurement window is equal in time to the channel path with the minimum delay.

[0294] In this embodiment, there is a first offset value between the time of the first channel sampling point in the channel measurement window and the time of the channel path with the minimum delay, so that the time of the first channel sampling point in the channel measurement window can be determined based on the time of the channel path with the minimum delay, and then the channel measurement window and the M channel sampling points in the channel measurement window can be determined.

[0295] In some embodiments, there is a first offset value between the time of the first channel sampling point in the X continuous channel sampling points and the time of the channel path with the minimum delay; wherein the time of the first channel sampling point in the X continuous channel sampling points is earlier than the time of the channel path with the minimum delay, or the time of the first channel sampling point in the X continuous channel sampling points is later than the time of the channel path with the minimum delay, or the time of the first channel sampling point in the X continuous channel sampling points is equal to the time of the channel path with the minimum delay.

[0296] In this embodiment, there is a first offset value between the time of the first channel sampling point in the X continuous channel sampling points and the time of the channel path with the minimum delay, so that the time of the first channel sampling point in the X continuous channel sampling points can be determined based on the time of the channel path with the minimum delay, and then the X continuous channel sampling points and the N continuous channel sampling points can be determined, and the M channel sampling points can be determined from the X continuous channel sampling points and the N continuous channel sampling points.

[0297] In some embodiments, the first offset value is in units of T1, and / or the first offset value is associated with k1, wherein T1 represents the timing granularity corresponding to the reporting of the channel sampling point, and k1 represents the timing reporting granularity factor corresponding to the reporting of the channel sampling point.

[0298] For example, the timing granularity reporting factor associated with the first offset value is k1, the timing granularity reporting factor associated with the duration of the channel measurement window is k1, the time difference between the first (time-minimal) channel sample point in the N consecutive channel sample points in the channel measurement window and the time-minimal channel path is T1*the first offset value. Specifically, as shown in FIG. 12, N=5, k1=4, k2=2, the first offset value=0, the index of the time-minimal channel path in the reporting grid of k2=2 is 5, the index of the time-minimal channel path in the reporting grid of k1=4 is 1 (determined based on the above formula 1), and based on the first offset value, it can be known that the index of the first channel sample point in the channel measurement window in the reporting grid of k1=4 is 1. As shown in FIG. 13, N=5, k1=4, k2=2, the first offset value=1, the index of the time-minimal channel path in the reporting grid of k2=2 is 5, the index of the time-minimal channel path in the reporting grid of k1=4 is 1 (determined based on the above formula 1), and based on the first offset value, it can be known that the index of the first channel sample point in the channel measurement window in the reporting grid of k1=4 is 2. As shown in FIG. 14, N=5, k1=4, k2=2, the first offset value=-1, the index of the time-minimal channel path in the reporting grid of k2=2 is 5, the index of the time-minimal channel path in the reporting grid of k1=4 is 1 (determined based on the above formula 1), and based on the first offset value, it can be known that the index of the first channel sample point in the channel measurement window in the reporting grid of k1=4 is 0.

[0299] In some embodiments, the first offset value is in units of T2, and / or the first offset value is associated with k2, wherein T2 represents the reporting corresponding timing granularity of the channel path, and k2 represents the reporting corresponding timing reporting granularity factor of the channel path.

[0300] For example, the timing granularity reporting factor associated with the first offset value is k2, the timing granularity reporting factor associated with the duration of the channel measurement window is k1, and the time difference between the first (time-minimum) channel sampling point in the N consecutive channel sampling points in the channel measurement window and the time-minimum channel path is T2*the first offset value. Specifically, as shown in FIG. 15, N=5, k1=4, k2=2, the first offset value=3, the index of the time-minimum channel path in the reporting grid of k2=2 is 5, and based on the first offset value, the index of the first channel sampling point in the channel measurement window in the reporting grid of k2=2 is 8. As shown in FIG. 16, N=5, k1=4, k2=2, the first offset value=-5, the index of the time-minimum channel path in the reporting grid of k2=2 is 5, and based on the first offset value, the index of the first channel sampling point in the channel measurement window in the reporting grid of k2=2 is 0. As shown in FIG. 17, N=5, k1=4, k2=2, the first offset value=-1, the index of the time-minimum channel path in the reporting grid of k2=2 is 5, and based on the first offset value, the index of the first channel sampling point in the channel measurement window in the reporting grid of k2=2 is 4.

[0301] In some embodiments, the time of the first channel sampling point in the N consecutive channel sampling points is equal to the time of the time-minimum channel path, or the time of the first channel sampling point in the X consecutive channel sampling points is equal to the time of the time-minimum channel path.

[0302] wherein the time of the time-minimum channel path is in units of T1, and / or the time of the time-minimum channel path is associated with k1, or the time of the time-minimum channel path is in units of T2, and / or the time of the time-minimum channel path is associated with k2.

[0303] wherein the T1 represents the reporting corresponding timing granularity of the channel sampling point, the k1 represents the reporting corresponding timing reporting granularity factor of the channel sampling point, the T2 represents the reporting corresponding timing granularity of the channel path, and the k2 represents the reporting corresponding timing reporting granularity factor of the channel path.

[0304] In the embodiment, the time of the first channel sampling point in the N continuous channel sampling points is equal to the time of the channel path with the minimum delay, so that the time of the channel path with the minimum delay can be taken as the time of the first channel sampling point in the N continuous channel sampling points, and then the N continuous channel sampling points are determined, and the M channel sampling points are determined from the N continuous channel sampling points. Alternatively, the time of the first channel sampling point in the X continuous channel sampling points is equal to the time of the channel path with the minimum delay, so that the time of the channel path with the minimum delay can be taken as the time of the first channel sampling point in the X continuous channel sampling points, and then the X continuous channel sampling points are determined, and the M channel sampling points are determined from the X continuous channel sampling points and the N continuous channel sampling points.

[0305] The time in the embodiment of the application is relative to the reference time. For example, the time of the channel path with the minimum delay relative to the reference time is 10, and the time of a channel sampling point relative to the reference time is 12, so that the time difference of the channel sampling point relative to the channel path with the minimum delay is 2.

[0306] The time difference in the embodiment of the application assumes that the same timing reporting granularity factor is associated with the two times (for example, the time of the channel path is processed by formula 1). Alternatively, the time in the embodiment of the application needs to be converted into the same time granularity before being added or subtracted. For example, the time of the channel path is converted into the time of the channel sampling point, and then the addition or subtraction operation is performed; or the time of the channel sampling point is converted into the time of the channel path, and then the addition or subtraction operation is performed; or the time of the channel path and the time of the channel sampling point are both converted into absolute time, and then the addition or subtraction operation is performed.

[0307] In some embodiments, the time information of the pth channel sampling point in the M channel sampling points is the time difference of the time of the pth channel sampling point relative to the time of the channel path with the minimum delay, where p is a positive integer, and 1≤p≤M.

[0308] In the embodiment, the time information of the pth channel sampling point in the M channel sampling points is the time difference of the time of the pth channel sampling point relative to the time of the channel path with the minimum delay, so that the time information of the channel sampling point can be reported more flexibly. For example, the first device can report the time of the channel path with the minimum delay and the time difference between the M sampling points and the time of the channel path with the minimum delay, so that the time of the M channel sampling points can be determined.

[0309] For example, M=4, k1=4, as shown in FIG. 18, the time of the channel path with the minimum delay is τ1, the time difference between the time of the first channel sampling point of the M channel sampling points and the time of the channel path with the minimum delay is Δτ1=1, the time difference between the time of the second channel sampling point of the M channel sampling points and the time of the first channel sampling point of the M channel sampling points is Δτ2=2, the time difference between the time of the third channel sampling point of the M channel sampling points and the time of the first channel sampling point of the M channel sampling points is Δτ3=4, and the time difference between the time of the fourth channel sampling point of the M channel sampling points and the time of the first channel sampling point of the M channel sampling points is Δτ4=6. As shown in FIG. 18, the time information of the M channel sampling points reported by the first device can specifically include: τ1, Δτ1=1, Δτ2=2, Δτ3=4, and Δτ4=6.

[0310] In some embodiments, the time information of the qth channel sampling point of the M channel sampling points is the time difference between the time of the qth channel sampling point and the time of the (q-1)th channel sampling point, and the time information of the first channel sampling point of the M channel sampling points is the time difference between the time of the first channel sampling point of the M channel sampling points and the time of the channel path with the minimum delay, where q is a positive integer and 2≤q≤M.

[0311] In this embodiment, the time information of the qth channel sampling point of the M channel sampling points is the time difference between the time of the qth channel sampling point and the time of the (q-1)th channel sampling point, and the time information of the first channel sampling point of the M channel sampling points is the time difference between the time of the first channel sampling point of the M channel sampling points and the time of the channel path with the minimum delay, so that the time information of the channel sampling points can be reported more flexibly.

[0312] For example, M=4, k1=4, as shown in FIG. 19, the time of the channel path with the minimum delay is τ1, the time difference between the time of the first channel sampling point of the M channel sampling points and the time of the channel path with the minimum delay is Δτ1=1, the time difference between the time of the second channel sampling point of the M channel sampling points and the time of the first channel sampling point of the M channel sampling points is Δτ2=1, the time difference between the time of the third channel sampling point of the M channel sampling points and the time of the second channel sampling point of the M channel sampling points is Δτ3=2, and the time difference between the time of the fourth channel sampling point of the M channel sampling points and the time of the third channel sampling point of the M channel sampling points is Δτ4=2. As shown in FIG. 19, the time information of the M channel sampling points reported by the first device can specifically include: τ1, Δτ1=1, Δτ2=2, Δτ3=4, and Δτ4=6.

[0313] In some embodiments, the time information of the pth channel sampling point of the M channel sampling points is a time difference of the time of the pth channel sampling point relative to the time of the first channel sampling point of the M channel sampling points, and the time information of the first channel sampling point of the M channel sampling points is a time difference of the time of the first channel sampling point of the M channel sampling points relative to a reference time, where p is a positive integer, and 2≤p≤M.

[0314] In this embodiment, the time information of the pth channel sampling point of the M channel sampling points is a time difference of the time of the pth channel sampling point relative to the time of the first channel sampling point of the M channel sampling points, and the time information of the first channel sampling point of the M channel sampling points is a time difference of the time of the first channel sampling point of the M channel sampling points relative to a reference time, so that the time information of the channel sampling points can be reported more flexibly.

[0315] For example, M=4, and k1=4. As shown in FIG. 20, the time of the first channel sampling point of the M channel sampling points is τ1, the time difference of the time of the second channel sampling point of the M channel sampling points relative to the time of the first channel sampling point of the M channel sampling points is Δτ1=1, the time difference of the time of the third channel sampling point of the M channel sampling points relative to the time of the first channel sampling point of the M channel sampling points is Δτ2=3, and the time difference of the time of the fourth channel sampling point of the M channel sampling points relative to the time of the first channel sampling point of the M channel sampling points is Δτ3=5. As shown in FIG. 20, the time information of the M channel sampling points reported by the first device can include τ1, Δτ1=1, Δτ2=3, and Δτ3=5.

[0316] In some embodiments, the time information of the qth channel sampling point of the M channel sampling points is a time difference of the time of the qth channel sampling point relative to the time of the q-1th channel sampling point, and the time information of the first channel sampling point of the M channel sampling points is a time difference of the time of the first channel sampling point of the M channel sampling points relative to a reference time, where q is a positive integer, and 2≤q≤M.
