[0041] A first model is trained based on the training sample set; wherein the first model can determine at least one type of perception result of the perception target based on the first information.
[0042] In the above embodiment, a model training method is provided to achieve successful training of the first model. The first model can determine at least one type of perception result of the perception target based on the input first information. It can be seen that the first model trained by the training method of the present disclosure is used to perceive the perception target, that is, the present disclosure provides a training method for a "perception model" so that the model can be successfully trained. Then, perception can be achieved based on the model in the future without having to calculate the perception result using the perception algorithm as in the related art. This effectively solves the technical problems such as the limited application scenarios when the perception algorithm calculates the perception result, the high complexity, and the poor perception accuracy in the case of multiple perception targets, thereby ensuring the perception accuracy, reducing the perception complexity, and broadening the perception application scenarios.

[0048] In the above embodiment, the specific categories of perception results are defined, and the correlation between the first information and different types of perception results is defined. This allows the trained first model to successfully output at least one type of perception result based on the first information, thereby realizing model-based perception, ensuring perception accuracy, reducing perception complexity, and broadening perception application scenarios.

Furthermore, multiple systems may be combined (for example, LTE or LTE-A combined with 5G) for application.
[0195] Optionally, in a communication system, it is often necessary to sense a sensing target to determine a sensing result of the sensing target. This sensing result may include, for example, the distance, speed, angle, etc. of the sensing target. Currently, the Integrated Sensing and Communication (ISAC) system can implement sensing and detection functions based on communication. It is one of the most important research directions in wireless communications and a key enabling technology in 5G-A (5G-Advanced) and future 6G mobile communications. Therefore, an ISAC system (or an ISAC simulation scenario) is often used to achieve sensing of the sensing target. Optionally, the ISAC simulation scenario typically includes a sensing signal transmitter, a sensing signal receiver, a sensing target, and an obstruction. The sensing signal transmitter can be used to transmit a sensing signal, and the sensing signal transmitted by the sensing signal transmitter can be directly transmitted to the sensing signal receiver, or the sensing signal can reach the sensing signal receiver after being reflected or refracted by the sensing target and / or obstruction; the obstruction may be, for example, another terminal or debris. Among them, considering that the transmission paths of the perception signals may be different, the following types of signals are mainly considered in the ISAC simulation scenario, namely: perception line of sight (LoS) path, perception non-line of sight (NLoS) path, clutter LOS path, and clutter NLOS path. Optionally, Figure 1B is a schematic diagram of the architecture of the perception LoS path, perception NLoS path, clutter LOS path, and clutter NLOS path in the ISAC simulation scenario according to an embodiment of the present disclosure. As shown in Figure 1B, the perception signal transmitter and the perception signal receiver are both base stations, the perception target is the vehicle in Figure 1B, and there is an obstruction between the base station and the vehicle. Among them, the transmission path without obstruction between the base station and the vehicle is the perception LOS path, the transmission path with obstruction between the base station and the vehicle is the perception NLOS path, the transmission path without obstruction between the base station and the obstruction is the clutter LOS path, and the transmission path with obstruction between the base station and the obstruction is the clutter NLOS path. Furthermore, after receiving the sensing signals of different paths, the sensing signal receiving end can measure the channel state information of the different paths based on the sensing signals of the different paths, and determine the sensing result of the sensing target based on the channel state information. The channel state information can be, for example, a channel state information matrix H, which is the superposition of the sensing target channel (such as the sensing LOS path, the sensing NLOS path, etc.), the clutter channel (such as the clutter LOS path, the clutter NLOS path, etc.) and the channel noise. The channel state information matrix H generally includes three dimensions: subcarrier, orthogonal frequency division multiplexing (OFDM) symbol, and receiving antenna port.Specifically, the channel state information matrix H represents the channel state information and is an M×N×P complex matrix, where M is the number of OFDM symbols, N is the number of subcarriers, and P is the number of receive antenna ports. The element in the channel state information matrix H at the position of the mth OFDM symbol, the nth subcarrier, and the pth receive antenna port is a complex number representing the impact on the amplitude and phase of the signal as it propagates from the transmit antenna to the receive antenna: H. m,n,p =C m,n,p =a m,n,p +i×b m,n,p .
[0196] Where C is a complex number, a is the real part of the complex number, b is the imaginary part of the complex number, a and b themselves are real numbers, and i is the imaginary unit.
[0197] Optionally, in some embodiments, the phase shifts in the three dimensions of the channel state information matrix H do not affect each other, and different types of perception results of the perception target can be obtained based on the phase changes in the three dimensions. For example, the distance estimation of the perception target can be completed based on the phase difference caused by the inter-subcarrier delay, the speed estimation of the perception target can be completed based on the phase difference caused by the Doppler effect between OFDM symbols, and the angle estimation of the perception target can be completed based on the phase changes between the received signals of multiple antenna ports. In addition, a three-dimensional sensing algorithm such as a three-dimensional detection algorithm (3D-MUSIC) and a 3D-ESPRIT can be used to obtain the perception results of the three parameters of the distance, speed, and angle of the perception target based on the channel state information matrix H. Optionally, Figure 1C is a schematic diagram of the architecture for determining the perception results based on the above-mentioned sensing algorithm (such as the aforementioned three-dimensional sensing algorithm) according to an embodiment of the present disclosure. As shown in Figure 1C, the above-mentioned sensing algorithm can be used to calculate the channel state information matrix H to obtain the distance perception result, speed perception result, and angle perception result of the perception target.
[0198] However, although the perception algorithm can achieve high accuracy in perceiving target distance, speed, angle, and other information in some ISAC application scenarios, the following major problems still exist:
[0199] (1) The applicability of perception algorithms to specific scenarios is limited
[0200] The performance of some perception algorithms can be significantly degraded by factors such as clutter and noise in the scene. For example, when clutter is introduced, the maximum eigenvalue estimated by the 3D ESPRIT algorithm may correspond to a clutter scatterer, degrading the performance of distance, velocity, and angle estimation. In the case of multiple perceived targets, the direct path of non-perceived targets can have a certain impact on the perception of perceived targets. When the perceived target is far away, the impact of noise is particularly significant.
[0201] (2) The computational complexity of the perception algorithm is high
[0202] In some cases, achieving highly accurate perception results requires a high level of algorithm complexity, hindering their practical application. For example, the 3D MUSIC and 3D ESPRIT algorithms can simultaneously calculate and obtain target distance, speed, and angle perception results, while achieving low perception errors. However, these algorithms require complex operations such as eigenvalue decomposition and spatial spectrum calculation, resulting in a high overall computational complexity.
[0203] (3) Accuracy in multi-target perception needs to be improved
[0204] In practical applications of synaesthesia integration, there may be multiple perception targets, necessitating the design of a multi-target perception algorithm to obtain perception results for multiple different perception targets. Existing multi-target perception algorithms often have errors when estimating the number of perception targets, resulting in large errors in the algorithm's estimation results.
[0205] Therefore, a perception method based on an AI model has been introduced. By inputting the channel state information of the perceived target into the AI model, the AI model directly outputs the perception result. This solves the technical problems of existing perception algorithms, such as limited application scenarios, high complexity, and poor perception accuracy in the case of multiple perceived targets. However, how to implement perception based on this AI model, as well as how to train and apply it, are urgent issues that need to be addressed.
[0206] FIG2A is an interactive diagram of a model training method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a model training method for a communication system 100, the method comprising:
[0207] Step 2101: The first device determines a training sample set.
[0208] Optionally, the first device may be a device for performing model training.
[0209] Optionally, the training sample set may be data used by the first device to train a model. The training sample set may include at least one set of sample data, and the sample data may include the first information and / or the second information.
[0210] Optionally, the above-mentioned first information may be channel state information determined by the perception signal receiving end based on the received perception signal, and the first information may be used to determine the perception result of the perception target. Optionally, the first information may be the channel state information matrix H described before the embodiment of Figure 2A. For a detailed introduction to the "channel state information matrix H", please refer to the description of the above embodiment. In addition, in some embodiments, the first information may include sub-information of at least one dimension, and sub-information of different dimensions may be used to determine different types of perception results. Among them, the perception result of the perception target includes at least one of the following categories: the distance of the perception target, the speed of the perception target, and the angle of the perception target. Furthermore, in some embodiments, when the first information is the channel state information matrix H described previously in the embodiment of FIG. 2A , the first information may include sub-information of three dimensions, and the sub-information of the three dimensions may be, respectively: sub-information corresponding to the “OFDM symbol” dimension (i.e., information related to the “OFDM symbol” dimension in the channel state information matrix H), sub-information corresponding to the “subcarrier” dimension (i.e., information related to the “subcarrier” dimension in the channel state information matrix H), and sub-information corresponding to the “receiving antenna port” dimension (i.e., information related to the “receiving antenna port” dimension in the channel state information matrix H). The sub-information corresponding to the “OFDM symbol” dimension can be used to determine the speed of the perceived target, the sub-information corresponding to the “subcarrier” dimension can be used to determine the distance of the perceived target, and the sub-information corresponding to the “receiving antenna port” dimension can be used to determine the angle of the perceived target. It should be noted that the "distance of the perceived target, the speed of the perceived target, and the angle of the perceived target" in the above content are only some examples of the perception results of the perceived target. The perception results may also include other results, such as: the perception results of the perceived target may also include the position of the perceived target, etc. The present disclosure does not make specific limitations on this, and other types of perception results are also within the scope of protection of the present disclosure.
[0211] Optionally, the above-mentioned second information may be actual state information of the perceived target; in some embodiments, the second information may include at least one of the following: actual distance of the perceived target, actual speed of the perceived target, actual angle of the perceived target. Optionally, the second information may be used as a label in a training sample set, for example. It should be noted that the "actual distance of the perceived target, actual speed of the perceived target, actual angle of the perceived target" in the above content are only some examples of the content included in the second information. The second information may also include other actual state information of the perceived target, such as: the second information may also include the actual position of the perceived target, etc. The present disclosure does not make specific limitations on this, and other actual state information of the perceived target that the second information may include is also within the scope of protection of the present disclosure.
[0212] Optionally, the aforementioned training sample set may be determined by a perception signal receiving end. Furthermore, in some embodiments, the first device may be a different device from the perception signal receiving end, or the first device may be the same device as the perception signal receiving end. When the first device and the perception signal receiving end are different devices, the training sample set may be sent by the perception signal receiving end to the first device. When the first device and the perception signal receiving end are the same device, the training sample set is determined by the first device based on the received perception signal.
[0213] Alternatively, in some other embodiments, the second information in the aforementioned training sample set may be sent by the sensing target to the first device.
[0214] Furthermore, in some embodiments, the first device can be used to train a first model, wherein the first model can be used to implement perception. The first model can be, for example, an AI perception model. Furthermore, the phrase "the first model can be used to implement perception" can be embodied as follows: the first model can determine at least one type of perception result of a perceived target based on the first information. Specifically, in some embodiments, the first model can determine a type of perception result of a perceived target based on the first information, and different first models are used to determine different types of perception results. For example, assume there are three first models, namely, first model #1, first model #2, and first model #3. First model #1 can determine the distance of a perceived target based on the first information, first model #2 can determine the speed of a perceived target based on the first information, and first model #3 can determine the angle of a perceived target based on the first information. Alternatively, in other embodiments, the first model can determine all perception results of a perceived target based on the first information, that is, the first model can determine the distance, speed, and angle of a perceived target based on the first information. Alternatively, in some other embodiments, the first model may also determine multiple categories of perception results of the perception target based on the first information, but not all perception results, and the perception results determined by different first models are different; for example, assuming there are three first models, namely first model #1, first model #2, and first model #3, wherein first model #1 can determine the distance and speed of the perception target based on the first information, first model #2 can determine the distance and angle of the perception target based on the first information, and first model #3 can determine the speed and angle of the perception target based on the first information. Alternatively, in some other embodiments, the number of categories of perception results determined by different first models may be different. For example, some first models may determine one category of perception results of the perception target based on the first information, and other first models may determine multiple categories of perception results or all perception results of the perception target based on the first information. This disclosure does not specifically limit this.
[0215] For example, in some embodiments, FIG2B is a schematic diagram of a first model used to output all perception results according to an embodiment of the present disclosure, and FIG2C is a schematic diagram of different first models used to output a type of perception results according to an embodiment of the present disclosure. As shown in FIG2B , the AI perception model (i.e., the aforementioned first model) can output the distance perception result, speed perception result, and angle perception result of the perception target based on the channel matrix H (i.e., the aforementioned channel state information matrix H). And, as shown in FIG2C , there are three first models, namely, a distance perception model, a speed perception model, and an angle perception model. The distance perception model is used to output the distance perception result of the perception target based on the distance perception information in the channel state information matrix H (i.e., the sub-information corresponding to the aforementioned "subcarrier" dimension), the speed perception model is used to output the speed perception result of the perception target based on the speed perception information in the channel state information matrix H (i.e., the sub-information corresponding to the aforementioned "OFDM symbol" dimension), and the angle perception model is used to output the angle perception result of the perception target based on the angle perception information in the channel state information matrix H (i.e., the sub-information corresponding to the aforementioned "receiving antenna port" dimension).
[0216] Step 2102: The first device determines at least one type of perception result that needs to be determined by the first model.
[0217] Optionally, in some embodiments, the specific categories of the at least one type of perception results that the first model needs to determine may be predefined by the protocol, or may be determined autonomously by the first device.
[0218] Step 2103: The first device determines third information based on the first information.
[0219] Optionally, in some embodiments, the first device may determine the third information from the first information based on at least one type of perception result that needs to be determined by the first model. The third information may be: sub-information of at least one dimension in the first information used to determine at least one type of perception result (i.e., at least one type of perception result that needs to be determined by the first model in step 2102). For example, when the at least one type of perception result that needs to be determined by the first model includes the speed and distance of the perceived target, the third information may be the sub-information corresponding to the "OFDM symbol" dimension and the sub-information corresponding to the "subcarrier" dimension in the first information.
[0220] Optionally, the method for the first device to determine the third information based on the first information may include at least one of the following:
[0221] Method 1: directly extracting sub-information of at least one dimension for determining at least one type of perception result from the first information as the third information.
[0222] Method 2: The sub-information of at least one dimension in the first information that is not used to determine at least one type of perception result is set to a fixed value (such as 0 or 1), and the first information after being set to the fixed value is determined as the third information.
[0223] For example, assuming that at least one type of perception result to be determined by the first model is: distance perception result, the first device can retain the data in the first information (i.e., the channel state information matrix H) that can reflect the distance characteristics of the perception target, i.e., N complex data on the subcarrier dimension, and set the OFDM symbol dimension data M and the receiving antenna port dimension data P in the first information (i.e., the channel state information matrix H) to fixed values, for example, let M=1, P=1, so as to determine the above-mentioned third information. Or
[0224] As another example, assuming that at least one type of perception result to be determined by the first model is speed perception result, the first device can retain the data in the first information (i.e., the channel state information matrix H) that can reflect the perception target speed characteristics, i.e., M complex data on the OFDM symbol dimension, and set the data N on the subcarrier dimension and the data P on the receiving antenna port dimension to fixed values, for example, let N=1, P=1, so as to determine the above-mentioned third information. Or
[0225] As another example, assuming that at least one type of perception result that the first model needs to determine is: angle perception result, the first device can retain the data in the first information (i.e., the channel state information matrix H) that can reflect the angle characteristics of the perception target, that is, P complex data in the receiving antenna port dimension, and set the data M in the OFDM symbol dimension and the data N in the subcarrier dimension to fixed values, for example, let M=1, N=1, so as to determine the above-mentioned third information.
[0226] It should be noted that, in other embodiments, the first device may also adopt other methods to determine the third information based on the first information, and this disclosure does not specifically limit this.
[0227] Optionally, in some embodiments, the above-mentioned methods for determining the third information can also be combined with each other. For example, assuming that the at least one perception result required to be determined by the first model includes a distance perception result and a speed perception result, the first device can use the above-mentioned method one to determine the sub-information used to determine the distance perception result from the first information, and use the above-mentioned method two to determine the sub-information used to determine the speed perception result from the first information, and then combine the determined sub-information into the third information.
[0228] It should also be noted that, in some embodiments, when the first model needs to determine all perception results of the perception target, the first information is the same as the third information.
[0229] Step 2104: The first device inputs the third information into the first model to obtain an output result of the first model.
[0230] Optionally, the output result of the first model may include at least one type of perception result determined by the first model based on the third information.
[0231] For example, assuming that the at least one type of perception result that needs to be determined by the first model determined by the first device in the above step 2102 is the speed, angle or distance of the perceived target, then the output result of the first model here is: the speed, angle or distance of the perceived target determined by the first model based on the third information; or, assuming that the at least one type of perception result that needs to be determined by the first model determined by the first device in the above step 2102 is the speed, angle and distance of the perceived target, then the output result of the first model here is: the speed, angle and distance of the perceived target determined by the first model based on the third information.
[0232] Step 2105: The first device calculates a loss function based on the output result of the first model and the second information.
[0233] Optionally, the first device can calculate the loss function by comparing the error between the output result of the first model and the actual state of the perceived target indicated by the second information. For example, assuming that the output result of the first model includes the speed of the perceived target, the first device can calculate the loss function by comparing the error between the speed of the perceived target output by the first model and the actual speed of the perceived target in the second information.
[0234] Step 2106: The first device adjusts the parameters of the first model based on the loss function, inputs the third information into the adjusted first model to obtain the output result of the first model, and then calculates the loss function of the first model until the first condition is met, and determines that the training is completed.
[0235] Optionally, the first condition may include, for example, at least one of the following:
[0236] The training cycle (or training times) of the first model reaches a first threshold;
[0237] The first model converges. The convergence of the first model can be understood as, for example, when the loss function of the first model decreases to a value smaller than a certain value, the model is considered to have converged.
[0238] Optionally, steps 2102-2106 above provide a method for training the first model by the first device in an embodiment of the present disclosure. It should be noted that, in other embodiments, the first device may also train the first model based on other methods. For example, the first device may train the first model based on a stochastic gradient descent (SGD) method. This disclosure does not impose any specific limitations on this.
[0239] Step 2107: The first device and the second device are different devices, and the first device sends fourth information to the second device.
[0240] Optionally, the second device may be a device for applying the first model, or may be an inference device for the first model. Furthermore, the fourth information may be used to indicate model parameters of the first model trained by the first device. After the second device receives the fourth information, the second device may deploy the first model based on the fourth information, so that the second device can subsequently successfully apply the first model for perception.
[0241] It should be noted that, in some embodiments, the first device and the second device may also be the same device.

[0327] The following is an exemplary introduction to the above method.
[0328] The AI-based synaesthesia integration implementation method proposed in the present disclosure mainly completes the perception of the distance, speed, and angle information of the target. To train the AI perception model, it is necessary to first collect a training data set, which contains a certain number of data samples. Each data sample is composed of a channel state information matrix H obtained by measuring the perception target and the actual distance d, speed v, and angle θ information of the perception target. As mentioned above, the channel matrix H of the perception target is an M×N×P complex matrix, which contains the distance, speed, and angle information of the perception target. Among them, the data change in the subcarrier dimension corresponds to the distance information of the perception target, the data change in the receiving antenna port dimension corresponds to the angle information of the target, and the data change in the OFDM symbol dimension corresponds to the speed information of the target. The actual distance d, speed v, and angle θ information of the perception target are labels in the model training data set.
[0329] During the model training process, the perception results output by the model, including distance speed angle The error between the label distance d, velocity v, and angle θ of the training set is used as the loss function. Model training is performed through methods such as stochastic gradient descent (SGD) to reduce the loss function, so that the model learns the mapping relationship between the input channel matrix and the output perception result. Model training is completed after a specific number of training cycles is reached or the model accuracy meets certain requirements.
[0330] Since the present disclosure mainly considers obtaining information on the three parameters of the perceived target, namely, distance, speed, and angle, and different dimensions of the perceived target channel state information matrix are related to different types of parameter information, the present disclosure proposes two target perception methods based on AI models.
[0331] (1) Simultaneous perception model of distance, speed, and angle
[0332] The channel state information matrix H is directly used as the input data of the AI perception model to train an AI perception model, which also outputs the distance of the target. speed angle The three types of perception results are shown in Figure 2B above.
[0333] (2) Distance, speed, and angle perception models
[0334] Combined with the perception algorithm, the data of different dimensions in the channel matrix are used to perceive the target distance, speed, and angle. Based on a part of the data in the channel matrix H, the three types of perception results of distance, speed, and angle are estimated respectively. Three AI perception models are trained to output distance and speed respectively. speed angle The three types of perception results are shown in Figure 2C above.
[0335] Data preprocessing refers to data extraction from the channel matrix H, specifically: mainly retaining the information in the channel matrix used for target distance perception, that is, the data in the subcarrier dimension, for training data of the distance perception model; mainly retaining the information in the channel matrix used for target speed perception, that is, the data in the OFDM symbol dimension, for training data of the speed perception model; mainly retaining the information in the channel matrix used for target angle perception, that is, the data in the receiving antenna port dimension, for training data of the angle perception model.
[0336] The distance, speed, and angle simultaneous perception model uses the channel state information matrix as input data for the AI model. The channel state information matrix contains data feature information about the distance, speed, and angle of the perceived target. The AI model can extract features based on the input channel state information matrix data and then output the perception results.
[0337] For the distance, speed, and angle perception models, it is necessary to first extract data based on the channel matrix. That is, to extract specific data corresponding to the perception result type from the original data, which can reflect the characteristics of the perceived target distance, speed, angle, etc. Specifically:
[0338] The original channel matrix is a complex matrix H, which contains complex data in three dimensions: OFDM symbols, subcarriers, and receiving antenna ports.
[0339] (1) Retain data in the channel matrix that can reflect the target distance characteristics, that is, data in the subcarrier dimension, as input data for the distance perception model. The processing method includes but is not limited to: setting M and P to certain values, for example, setting M = 1 and P = 1, and obtaining N complex data in the subcarrier dimension.
[0340] (2) Retaining data in the channel matrix that can reflect the target speed characteristics, that is, data in the OFDM symbol dimension, as input data for the speed perception model. The processing method includes but is not limited to: setting N and P to certain values, for example, setting N = 1 and P = 1, and obtaining M complex data in the OFDM symbol dimension.
[0341] (3) Retaining data in the channel matrix that can reflect the target angle characteristics, that is, data in the receiving antenna port dimension, as input data for the angle perception model. The processing method includes but is not limited to: setting M and N to specific values, for example, setting M = 1 and N = 1, and obtaining P complex data in the receiving antenna port dimension.
[0342] This disclosure only provides one possible way of data preprocessing.
[0343] The AI-based target perception solution proposed in this disclosure includes, but is not limited to, three types of information: distance, speed, and angle of the perceived target. These three types of information are the most commonly used types of perception parameters in synaesthesia integration applications and can meet the needs of most application scenarios. Using the same ideas as this solution, the perception of other types of parameters can also be achieved. Moreover, when perceiving different types of results, different data feature extraction methods can be selected, and different methods can be combined with each other.
[0344] In addition, the specific structure of the AI perception model proposed in this disclosure for perceiving target distance, speed, angle and other information depends on the design and deployment in the actual application process.
[0345] As can be seen from the above, in the application scenario of integrated communication and perception, the strong learning and modeling capabilities of neural network models can be utilized to train an AI perception model based on a certain amount of data, thereby completing the perception of target distance, speed, angle, and other information. To address the shortcomings of existing traditional perception algorithms, such as limited scenario applicability, high computational complexity, and low accuracy in multi-target perception, this disclosure uses perception datasets to train an AI neural network model, achieving optimizations in perception accuracy, computational complexity, and scope of application, thereby promoting the further development of integrated communication and perception technology.
[0346] Furthermore, the present disclosure proposes a method for perceiving target distance, speed, angle and other information based on an AI neural network model for integrated communication and perception application scenarios. In different integrated communication and perception application scenarios, an AI perception model is trained based on a data set consisting of the channel state information matrix of the perceived target and its actual distance, speed, angle and other parameter information, which can achieve target distance, speed and angle perception with high accuracy. The AI-based target perception solution has a large scope of application, which is conducive to solving the shortcomings of traditional perception algorithms such as limited application scenarios, high complexity, and poor perception accuracy in multi-target situations, thereby promoting the development and application of integrated communication and perception technology.
