[0038] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0039] This disclosure provides a data processing method, a first device, and a storage medium.

[0040] In a first aspect, embodiments of this disclosure propose a data processing method, the method comprising: acquiring first data; wherein the first data is raw channel measurement data for device sensing of a second device; removing noise from the first data to obtain second data; and performing device sensing on the second device based on the second data to determine the device sensing result.

[0041] In the above embodiments, the first device can remove noise from the original data used for device sensing and perform device sensing based on the noise-removed data, thereby improving the reliability of device sensing.

[0042] In conjunction with some embodiments of the first aspect, in some embodiments, obtaining the first data includes: receiving the first data sent by a third device.

[0043] In the above embodiments, the first device can directly obtain the raw data for device sensing from the third device, thereby improving the usability of ISAC technology.

[0044] In conjunction with some embodiments of the first aspect, in some embodiments, obtaining the first data includes: receiving a second signal; wherein the second signal is determined based on the first signal; wherein the first signal is a signal used to initiate device sensing; and performing channel measurement based on the second signal to obtain the first data.

[0045] In the above embodiments, the first device can perform channel measurement based on the received second signal to obtain raw data for device sensing, thereby improving the availability of ISAC technology.

[0046] In conjunction with some embodiments of the first aspect, in some embodiments, removing noise from the first data to obtain the second data includes: using the first data as input to a first artificial intelligence (AI) model to obtain the second data output by the first AI model; wherein the first AI model is used to remove the noise.

[0047] In the above embodiments, noise in the raw data for device sensing can be removed by artificial intelligence models, which improves the reliability of device sensing and is conducive to promoting the integrated development of communication, sensing and artificial intelligence.

[0048] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes: inputting first sample data into a first initial AI model to obtain third data output by the first initial AI model; wherein the first sample data is raw sample channel measurement data used for device perception; determining a first loss function based on the difference between the third data and the fourth data; wherein the fourth data is data used for device perception and with the noise removed; training the first initial AI model based on the first loss function until a first stopping condition is met to stop training and obtain the first AI model.

[0049] In the above embodiments, a first AI model for noise removal can be trained through the above process. Subsequently, noise in the original data used for device perception can be directly removed through the first AI model, thereby improving the reliability of device perception and promoting the combined development of perception and artificial intelligence.

[0050] In conjunction with some embodiments of the first aspect, in some embodiments, the first stopping condition includes at least one of the following: reaching a first number of training epochs; the first loss function decreasing to a first tolerance range; and the noise removal accuracy of the first initial AI model reaching a first value.

[0051] In the above embodiments, when the training process of the first initial AI model meets the first stopping condition, the training can be stopped, thereby obtaining the first AI model. This improves the efficiency of training the first AI model and ensures the accuracy of noise removal, resulting in high usability.

[0052] In conjunction with some embodiments of the first aspect, in some embodiments, the step of performing device perception on the second device based on the second data and determining the device perception result includes: using the second data as the input value of the second AI model to obtain the device perception result output by the second AI model; wherein, the second AI model is used to perform device perception.

[0053] In the above embodiments, the device perception results can be obtained through the second AI model, which promotes the development of the combination of perception and artificial intelligence.

[0054] In conjunction with some embodiments of the first aspect, in some embodiments, the noise includes at least one of the following: Gaussian white noise; fifth data; wherein the fifth data is channel measurement data used for device awareness of a fifth device.

[0055] In the above embodiments, the noise involved in this disclosure may include, but is not limited to, Gaussian white noise during channel transmission, and may also include data used for device sensing of non-sensing targets. By removing the above noise, the obtained device sensing result is closer to the device sensing result corresponding to the sensing target itself, thereby improving the reliability of device sensing.

[0084] Figure 1A is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0085] As shown in Figure 1A, the communication system 100 includes a first device 101, a second device 102, a third device 103, and a fourth device 104.

[0086] In some embodiments, the first device 101 may be a device for performing device sensing and determining the results of device sensing.

[0087] In some embodiments, a second artificial intelligence (AI) model may be deployed on the first device 101 to perform device perception.

[0088] In some embodiments, the first device 101 may be a terminal or a network device, such as an access network device or a core network device. In some embodiments, the terminal includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0089] In some embodiments, the access network device is, for example, a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.

[0090] In some embodiments, the first device 101 may be an autonomous driving device, an Internet of Things (IoT) device, an environmental IoT device, etc. Autonomous driving devices include, but are not limited to, driverless cars and drones. IoT devices include, but are not limited to, sensors using radio frequency identification (RFID), scanners, smart home devices, and robots. Environmental IoT devices include, but are not limited to, IoT devices that can obtain energy from the outside environment and be charged.

[0091] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0092] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0093] In some embodiments, the core network equipment can be a single device, including a first network element, a second network element, etc., or it can be multiple devices or a group of devices, each including all or part of the first network element, the second network element, etc. Network elements can be virtual or physical. The core network includes, for example, at least one of the Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC).

[0094] In some embodiments, the core network device is, for example, a Location Management Function (LMF).

[0095] In some embodiments, core network devices are used for device awareness, and the names are not limited to device awareness network elements or functions.

[0096] In some embodiments, the second device 102 may be a device that needs to be sensed.

[0097] In some embodiments, the second device 102 may be a sensing target device. A "sensing target" may refer to a device or terminal that is expected to determine the sensing results of its device.

[0098] In some embodiments, the first device 101 may be used to determine the device perception result of the second device 102.

[0099] In some embodiments, the second device 102 may be a terminal, or an autonomous driving device, an Internet of Things (IoT) device, an environmental IoT device, etc.

[0100] In some embodiments, the third device 103 may be a sensing signal receiving device.

[0101] In some embodiments, the third device 103 can obtain first data after performing channel measurements based on the received signal.

[0102] For example, the name of the received signal is not limited and can be interchanged with the second signal, the transmitted signal, etc.

[0103] In some embodiments, the first data may refer to data used for device awareness of the second device 102. Exemplarily, the first data may include, but is not limited to, channel state information (CSI).

[0104] For example, the name of the first data is not limited and can be interchanged with channel state information, device sensing data, etc.

[0105] In some embodiments, the third device 103 may be a terminal, a network device, an autonomous driving device, an IoT device, an environmental IoT device, etc. Specific details will not be elaborated further here.

[0106] In some embodiments, the fourth device 104 may be a device that transmits sensing signals, such as a sensing signal transmitting device.

[0107] In some embodiments, the sensing signal is a signal that enables the second device 102 (i.e., the sensing target) to be sensed.

[0108] In some embodiments, the sensing signal may be a signal used to initiate device sensing.

[0109] In one example, after the fourth device 104 sends a sensing signal, the sensing signal is received by the third device 103 after being propagated through the second device 102 (i.e., the sensing target) or other objects through reflection, refraction and / or scattering. The signal received by the third device 103 is called the second signal.

[0110] For example, the name of the sensing signal is not limited and can be interchanged with the first signal, the transmitted signal, etc.

[0111] The aforementioned other objects may include, for example, network devices, vehicles, environmental IoT devices, IoT devices, etc., and this disclosure does not limit them.

[0112] In some embodiments, the sensing results include, but are not limited to, the distance (distance of the second device 102 relative to the specified object), speed (moving speed of the second device 102), angle (horizontal angle and / or zenith angle of the second device 102 relative to the specified object), etc.

[0113] For example, the horizontal angle refers to the angle obtained by projecting the lines connecting the second device 102 and the designated object from a reference point, such as the Earth's center or other designated location, onto the horizontal plane. The zenith angle refers to the angle of the line connecting the second device 102 and the designated object relative to the ground normal.

[0114] Specifically, determining the perception results of the second device can refer to determining the specific values ​​of the three parameters of the second device: distance, speed, and angle.

[0115] For example, if the first signal is sent by the second device 102 itself, and the second device 102 receives the second signal, the specified object can be other objects that propagate the first signal through the above-described propagation methods such as emission, refraction and / or scattering, such as network devices, vehicles, IoT devices, environmental IoT devices, etc.

[0116] For example, if the first signal is sent by a fourth device 104 (a device different from the second device 102), the designated object may refer to the second device 102.

[0117] In some embodiments, the second device 102, the third device 103, and the fourth device 104 may be the same device. For example, after the second device 102 sends a first signal, it receives a second signal after the propagation process of emission, refraction, and / or scattering through a first object (network device, vehicle, environmental IoT device, IoT device, etc.). At this time, the second device 102 needs to determine its own device sensing result.

[0118] Furthermore, if the second device 102 and the first device 101 are the same device, the second device 102 performs channel measurement based on the second signal to obtain the first data, and performs device perception on itself based on the first data to determine the device perception result. The device perception result may include, but is not limited to, the specific values ​​of parameters such as distance, speed and angle of the second device 102.

[0119] If the second device 102 and the first device 101 are different devices, the second device 102 performs channel measurement based on the second signal to obtain first data, and sends the first data to the first device 101. The first device 101 performs device perception on the second device 102 based on the first data and determines the device perception result of the second device 102. The device perception result may include, but is not limited to, specific values ​​of parameters such as distance, speed and angle of the second device 102.

[0120] In some embodiments, the second device 102, the third device 103, and the fourth device 104 may be different devices.

[0121] For example, the fourth device 104 sends a first signal, which is then transmitted through the second device 102 via emission, refraction, and / or scattering, and finally received by the third device 103.

[0122] Furthermore, if the third device 103 and the first device 101 are the same device, the third device 103 performs channel measurement based on the second signal to obtain first data, and performs device perception on the second device 102 based on the first data to determine the device perception result. The device perception result may include, but is not limited to, specific values ​​of parameters such as distance, speed and angle of the second device 102.

[0123] If the third device 103 and the first device 101 are different devices, the third device 103 performs channel measurement based on the second signal, obtains the first data, and sends the first data to the first device 101. The first device 101 performs device perception on the second device 102 based on the first data and determines the device perception result of the second device 102. The device perception result may include, but is not limited to, the specific values ​​of parameters such as distance, speed and angle of the second device 102.

As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0127] In this disclosed embodiment, ISAC is one of the most important research directions in wireless communication and a key enabling technology in mobile communication. Sensor-integrated communication technology can enable sensing services based on existing mobile communication infrastructure, fully leverage the advantages of mobile communication networks to meet the sensing needs of various service scenarios, and improve communication performance by relying on sensing capabilities. This, in turn, helps to realize numerous application services such as detection, localization and tracking, environmental reconstruction and target imaging, gesture and posture recognition, etc.

[0128] In some embodiments, for integrated communication and sensing applications, relatively complete channel modeling of the sensing system has been carried out based on relevant channel modeling standards, providing strong support for the evaluation of sensing technology solutions. For scenarios such as highways, various estimation algorithms for parameters such as target speed, distance, and angle have been proposed and designed, including but not limited to the Multiple Signal Classification (MUSIC) algorithm and the Estimation of Signal Parameters using Rotational Invariance Techniques (ESPRIT) algorithm. These algorithms can achieve good target perception results in integrated communication and sensing simulation scenarios.

[0129] The application of AI technology in the field of wireless communication is also one of the important research topics. AI technology has been widely used in many fields. The powerful feature extraction and mapping relationship modeling capabilities of neural network models can provide new solutions to key problems in wireless communication systems. It can be widely used and studied in problems such as high-precision terminal positioning, channel state information feedback, and beam management.

[0130] The integration of communication and sensing based on AI technology is a potential application in future wireless communication systems. By leveraging the powerful computing capabilities of graphics processing units (GPUs), AI sensing models can be trained and acquired based on sample datasets. This can optimize aspects such as sensing accuracy, computational complexity, and applicability, promoting the deep application of communication and sensing integration technology, supporting more intelligent business applications and services, and thus contributing to the development of the integration of communication, sensing, algorithms, and AI.

[0131] In this embodiment, the following six sensing modes are provided, as shown in Figure 1B. Mono-static indicates self-transmission and self-reception, meaning the sending and receiving ends are the same; Bi-static indicates cross-station transmission and reception, meaning the sending and receiving ends are different.

[0132] Sensing Mode 1 is a self-transmitting and self-receiving mode where both the transmitter and receiver are User Equipment (UE), such as a user (person). The transmitter sends a sensing signal to another UE (e.g., a car) and receives the reflected echo from the other UE (car), thereby sensing the user's (person's) device sensing result.

[0133] Sensing Mode 2 is a self-transmitting and self-receiving mode where both the transmitter and receiver are User Equipment (UE), such as a user (person). The transmitter sends a sensing signal to the access network device, such as a gNB, and receives the reflected echo from the gNB to perceive the sensing results of itself (the person).

[0134] Sensing mode 3, cross-site transceiver, the transmitting end is gNB and the receiving end is UE (vehicle). For example, gNB sends a sensing signal and UE (vehicle) receives the signal forwarded by the user (person). UE (vehicle) calculates the channel matrix based on the received signal to sense the target in the environment, such as the user (person), and the device sensing result.

[0135] Sensing mode 4, cross-site transceiver, the transmitting end is UE (vehicle) and the receiving end is gNB. For example, the UE (vehicle) sends a sensing signal and the gNB receives the signal forwarded by the user (person). The gNB calculates the channel matrix based on the received signal to sense the target in the environment, such as the user (person), and the device sensing result.

[0136] Sensing mode 5, cross-site transmission and reception, with gNB#1 as the transmitter and gNB#2 as the receiver. For example, gNB#1 transmits a sensing signal, and gNB#2 receives the signal forwarded by the user (person). gNB#2 calculates the channel matrix based on the received signal to sense the device sensing results of targets in the environment, such as users (persons).

[0137] Sensing mode 6, cross-site transceiver, the transmitting end is UE#1 (vehicle #1) and the receiving end is UE#2 (vehicle #2). For example, UE#1 (vehicle #1) sends a sensing signal and UE#2 (vehicle #2) receives the signal forwarded by the user (person). UE#2 (vehicle #2) calculates the channel matrix based on the received signal to sense the target in the environment, such as the user (person), and the device sensing result.

[0138] It is understood that the aforementioned sensing target, namely the second device 102, can include: drones, people in indoor and outdoor scenarios, cars on highways in outdoor scenarios, automated guided vehicles in factories in indoor scenarios, and targets that create danger on roads or railways, etc. Sensor integration mainly involves the receiver calculating and acquiring information such as the distance, speed, and angle of the sensing target in the environment based on the received signal. The sensing target can be the receiver itself or other objects.

[0139] In some embodiments, taking self-transmitting and self-receiving as an example, the fourth device 104, the third device 103, and the second device 102 are the same device, assumed to be a vehicle. Other objects (also referred to as "sensing signal reflection ends") are assumed to be gNBs, as shown in Figure 1C. In this scenario, there are obstructions between the vehicle and the gNB; these obstructions may be other UEs or other debris. Four types of signals can be considered in the sensing channel model:

[0140] Line of sight (LOS) path; Non-line of sight (NLOS) path; Clutter LOS path; Clutter NLOS path.

[0141] For example, in addition to the four types of signals mentioned above, the impact of channel noise usually needs to be considered.

[0142] For example, as shown in Figure 1C, the above four types of signals are described below:

[0143] The path of perception LOS is the path between the sensing signal reflector (e.g., gNB) and the sensing target (e.g., vehicle). The path between the sensing target (e.g., vehicle) and the sensing signal receiver (e.g., gNB) is also a path of perception LOS (e.g., solid line path #1 between gNB and vehicle in Figure 1C).

[0144] Sensing NLOS path: The path between the sensing signal reflector (e.g., gNB) and the sensing target (e.g., vehicle) that needs to pass through clutter (e.g., clutter #1) is the sensing NLOS path. The path between the sensing target (e.g., vehicle) and the sensing signal receiver (e.g., gNB) that needs to pass through clutter is also the sensing NLOS path (e.g., solid line path #2 in Figure 1C).

[0145] Clutter LOS path: The path between the sensing signal reflector (e.g., gNB) and the scattering cluster in the environment (e.g., clutter #2) is the clutter LOS path. The path between the scattering cluster in the environment (e.g., clutter #2) and the sensing signal receiver (e.g., vehicle) is also the clutter LOS path (e.g., the dashed path #1 in Figure 1C).

[0146] Clutter NLOS path: The path between the sensing signal reflector (e.g., gNB) and the scattering cluster in the environment (e.g., clutter #2) that still needs to pass through clutter (e.g., clutter #3) is the sensing NLOS path. The path between the scattering cluster in the environment (e.g., clutter #3) and the sensing signal receiver (e.g., vehicle) that still needs to pass through clutter (e.g., clutter #2) is also the sensing NLOS path (e.g., the dashed path #2 in Figure 1C).

[0147] In this embodiment, the main information for device sensing is the Channel State Information (CSI) matrix H of the receiving end. This CSI matrix H is a superposition of the sensing target channel, clutter channel, and noise, reflecting the channel environment in which the sensing signal resides and the state information of the sensing target within that environment. The dimensions of the CSI matrix H are related to the specific parameter settings in the actual sensing scenario; the information in the data on different dimensions can reflect different types of state information of the sensing target. This embodiment presents one possible scenario:

[0148] The CSI matrix H typically includes three dimensions: subcarriers, Orthogonal Frequency Division Multiplexing (OFDM) symbols, and receiver antenna ports.

[0149] Specifically, the CSI matrix H can be an M×S×P complex matrix, where M is the number of OFDM symbols, S is the number of subcarriers, and P is the number of receive antenna ports. The element H at the position of the m-th OFDM symbol, the s-th subcarrier, and the p-th receive antenna port in the CSI matrix H is... m,s,p For a complex number Z m,s,p For example, as shown in Equation 1, it represents the influence of the signal's amplitude and phase on its propagation from the transmitting antenna to the receiving antenna: H m,s,p =Z m,s,p =a m,s,p +i×b m,s,p Formula 1

[0150] Among them, a m,s,p b m,s,p Used to represent the complex number Z m,s,p The values ​​of the real part and the imaginary part. Where, a m,s,p b m,s,p It can be a real number.

[0151] According to the received signal model, the phase shifts in the three dimensions of the channel matrix are independent of each other, and different types of sensing results for the target can be obtained based on the phase changes in the three dimensions. For example, the distance of the sensing device can be estimated based on the phase difference caused by the time delay between subcarriers, the velocity of the sensing device can be estimated based on the phase difference caused by the Doppler effect between OFDM symbols, and the angle of the sensing device can be estimated based on the phase changes between the received signals of multiple antenna ports. Sensing algorithms such as 3D-MUSIC (3-Dimensional Multiple Signal Classification) and 3D-ESPRIT (3-Dimensional Estimation of Signal Parameters using Rotational Invariance Techniques) can obtain the sensing results of the distance, velocity, and angle of the sensing device based on the channel state information matrix, as shown in Figure 1D.

[0152] In some embodiments, the scene applicability of the perception algorithm is affected by factors such as clutter and noise in the scene, and its performance will be significantly reduced. In the case of multiple targets, the direct path of non-perceived targets will have a certain impact on the perception results of perceived targets, and when the perceived target is far away, the impact of noise will be greater.

[0153] In some embodiments, the computational complexity of the perception algorithm is high. In order to obtain a high-accuracy perception result, the perception algorithm is complex and the application process of the perception algorithm is complicated.

[0154] In some embodiments, the accuracy needs to be improved in the case of multi-target perception. In actual integrated sensing application scenarios, existing multi-target perception algorithms usually have certain errors when estimating the number of sensing targets, resulting in large errors in the algorithm estimation results.

[0155] Leveraging the strong learning and modeling capabilities of neural network models, an AI perception model can be trained and acquired based on a sample dataset. This model can estimate the number of perceived targets and perceive information such as distance, velocity, and angle for each target in multi-target perception scenarios. For example, by directly using the channel state information matrix H as input data to the AI ​​perception model, a model can be trained that can simultaneously output the distance to the targets. speed angle The three types of perception results are shown in Figure 1E.

[0156] AI-based target perception models may be deployed on user devices such as mobile terminals and automobiles, or on the network side specifically for implementing sensing functions. The device that acquires channel measurement data for AI perception may differ from the device that performs the AI ​​perception model inference application. When the AI ​​perception model is deployed on a user device, the user device can acquire channel measurement data through self-transmission and self-reception, such as receiving the channel matrix and directly inputting it into the AI ​​perception model to obtain the perception results.

[0157] In wireless communication systems, data transmission via wireless communication links is affected by channel noise, causing a certain deviation between the received data and the original transmitted data. Furthermore, in target information perception tasks, AI perception algorithms and models primarily rely on the channel state information matrix corresponding to the perceived target to complete target information perception. The channel state information matrix of non-perceived targets can be considered an interference factor in the target perception process, affecting the accuracy of target information perception. In practice, the channel matrix that the sensing signal receiver, such as a UE or base station, can measure is a superposition of the channel matrix of the perceived target and the channel matrix of the non-perceived target. After the sensing signal receiver reports the sensing measurement data to the AI ​​perception model inference node, such as the LMF, the model input data is then superimposed with noise. Therefore, if the channel measurement data reported by the sensing signal measurement node is directly used as the input data of the AI ​​perception model, the interference from non-perceived targets and noise will affect the perception accuracy.

[0158] To improve the reliability of device sensing, this disclosure provides the following data processing method, a first device, and a storage medium.

[0159] Figure 2A is an interactive schematic diagram of a data processing method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiments of the present disclosure relate to a data processing method, which includes:

[0160] In step S2101, the fourth device 104 sends the first signal.

[0167] In some embodiments, the fourth device 104 and the third device 103 are the same device. Corresponding to the above-mentioned sensing mode 1 or sensing mode 2, the fourth device 104 sends a first signal, which is then received by the fourth device 104 (i.e. the third device 103) after being propagated by a first object, such as, but not limited to, a base station, a vehicle, an IoT device, an environmental IoT device, etc., through reflection, refraction and / or scattering. The received signal is the second signal.

[0168] In some embodiments, the fourth device 104 and the third device 103 are different devices, corresponding to any of the above-mentioned sensing modes 3 to 6. The fourth device 104 sends a first signal, which is then received by the third device 103 after being propagated through reflection, refraction and / or scattering by the second device 102. The received signal is the second signal.

[0169] In one example, the second device 102 is the sensing target device, that is, the device that needs to be sensed.

[0170] In this embodiment of the disclosure, it is necessary to determine the device perception result of the second device 102.

[0187] In some embodiments, a first AI model is used to remove the noise.

[0188] In some embodiments, the first device 101 may remove the noise in other ways, such as non-AI methods, including but not limited to filtering the noise through devices such as filters, or filtering the noise using noise reduction algorithms. This disclosure does not limit the scope of the noise removal process.

[0189] In some embodiments, to improve the availability of AI in synesthesia, the noise can be removed using a first AI model.

[0190] In one example, the first data can be used as the input value of the first AI model, and the output value of the first AI model can be obtained. This output value is the second data.

[0191] In one example, the first AI model has determined the mapping relationship between noisy data and noise-removed data, and the second data can be obtained based on this mapping relationship.

[0192] In one example, the mapping could be a mapping between a CSI matrix with Gaussian white noise and fifth data and an ideal CSI matrix.

[0193] For example, an ideal CSI matrix may refer to a noise-free CSI matrix, or a CSI matrix that, although noisy, includes noise whose impact on the final device perception result is negligible.

[0243] In some embodiments, the first device may acquire the true value of the device perception result corresponding to the fourth data. Specifically, the true value of the device perception result may include the true values ​​of the three parameters corresponding to the "perceived target": distance, speed, and angle. The number of perceived targets may be one or more, and this disclosure does not limit this.

[0244] In some embodiments, the second loss function may be determined based on the difference between the device perception prediction result output by the second initial AI model and the true value of the device perception result.

[0245] Step S2303: Based on the second loss function, train the second initial AI model until the second stopping condition is met, and then stop training to obtain the second AI model.

[0299] The above process is further illustrated with examples below.

[0300] In some embodiments, this disclosure proposes a channel measurement data de-interference processing method for AI sensing. After the AI ​​sensing model inference node (LMF) acquires the channel measurement data for sensing reported by the UE or base station, it processes the channel measurement data based on the AI ​​data de-interference model, obtaining model output data close to the sensing target channel as input data for the AI ​​sensing model, thereby improving the target information sensing accuracy of the AI ​​sensing model. The application flow of the AI-based sensing measurement signal de-interference processing method proposed in this invention is shown in Figure 4A.

[0301] The AI-based interference-reduction processing model for sensing measurement signals uses channel measurement data, such as the channel state information matrix, received by the sensing model's inference node as input, and the sensing target channel matrix used for target perception as the label output for training. This allows the model to learn the mapping relationship between channel matrix data under noisy and non-sensory target interference conditions and the ideal sensing target channel matrix data. In practical system applications, the AI ​​sensing model's inference node can first process the data based on the interference-reduction model to obtain data close to the ideal sensing target channel as input data for the AI ​​sensing model, effectively improving the sensing accuracy of the AI ​​sensing model.

[0302] When applying the channel measurement data de-interference method for AI perception proposed in this disclosure, the overall application process is shown in Figure 4B, including the following steps:

[0303] Step S4201: Acquire sensing measurement data.

[0304] The sensing signal receiving device measures and obtains raw channel measurement data for AI sensing based on the sensing signals sent by the sensing signal transmitting device, including but not limited to the channel state information matrix.

[0305] Step S4202: Report the sensing measurement data.

[0306] The sensing signal receiving device reports channel measurement data to the sensing model inference device.

[0307] Step S4203: Sensing measurement data interference removal processing.

[0308] The perception model inference device inputs the received channel measurement data into the AI ​​interference removal model to obtain the interference-removed data.

[0309] Step S4204, AI perception model inference.

[0310] The perception model inference device inputs the interference-free processed data into the AI ​​perception model to obtain the perception results.
