[0091] To better understand the technical solution of this application, the following contents are first introduced:

[0092] Artificial Intelligence (AI) is currently being widely used in various fields. There are many ways to implement AI modules, such as neural networks, decision trees, support vector machines, and Bayesian classifiers. This application uses neural networks as an example, but does not limit the specific type of AI module.

[0093] A schematic diagram of a neural network is shown in Figure 1b:

[0094] The neural network is composed of neurons, and the schematic diagram of neurons is as follows. 1， a 2， …a K is the input, w is the weight (multiplicative coefficient), b is the bias (additive coefficient), and σ(.) is the activation function. Common activation functions include Sigmoid, Tanh, and Rectified Linear Unit (ReLU).

[0095] Neural network parameters are optimized using a gradient optimization algorithm. Gradient optimization algorithms are a class of algorithms that minimize or maximize an objective function (sometimes called a loss function), which is often a mathematical combination of model parameters and data. For example, given data X and its corresponding label Y, we construct a neural network model f(.). With this model, we can obtain the predicted output f(x) based on the input x, and calculate the difference between the predicted value and the true value (f(x) - Y). This is the loss function. Our goal is to find the appropriate W, b to minimize the value of this loss function. The smaller the loss value, the closer our model is to the true value.

[0096] As shown in Figure 1c, currently common optimization algorithms are generally based on the error back propagation (BP) algorithm. The basic concept of the BP algorithm is that the learning process consists of two steps: forward signal propagation and backward error propagation. During forward propagation, input samples are passed from the input layer, processed layer by layer through each hidden layer, and then transmitted to the output layer. If the actual output of the output layer does not match the expected output, the error back propagation phase begins. Error back propagation involves propagating the output error back through the hidden layers to the input layer layer by layer in some form, distributing the error to all units in each layer. This error signal is then generated for each unit in each layer, and used as the basis for adjusting the weights of each unit. This process of adjusting the weights of each layer, through forward signal propagation and backward error propagation, is repeated over and over again. This continuous adjustment of weights is the network's learning and training process. This process continues until the error in the network output is reduced to an acceptable level, or until a pre-set number of learning cycles is reached.

[0097] Depending on the type of solution, the selected AI algorithm and the AI ​​model used are also different. At present, the main method of using AI to improve the network performance of the fifth generation mobile communication technology (5G) is to enhance or replace the existing algorithms or processing modules through algorithms and AI models based on neural networks. In specific scenarios, algorithms and AI models based on neural networks can achieve better performance than those based on deterministic algorithms. The more commonly used neural networks include deep neural networks, convolutional neural networks, and recurrent neural networks. With the help of existing AI tools, the construction, training and verification of neural networks can be achieved.

[0098] Replacing modules in existing systems with AI / machine learning (ML) methods can effectively improve system performance.

[0099] For example, in the CSI prediction process below, historical CSI is fed into the AI ​​model, which then analyzes the channel's temporal variation characteristics and outputs future CSI, as shown in Figure 1d.

[0100] The corresponding system performance is shown in Figure 1e. It can be seen that CSI prediction offers significant performance gains compared to the non-prediction solution. Furthermore, the achievable prediction accuracy varies depending on the future time being predicted.

[0101] The above-mentioned CSI prediction is only a time domain prediction, and the current standard discussion only involves time domain prediction. Based on AI, other CSI prediction functions such as CSI time domain interpolation, CSI frequency domain interpolation, CSI spatial domain interpolation, CSI frequency domain extrapolation / prediction, and CSI spatial domain prediction / extrapolation can also be realized. However, the solutions and standards for time domain prediction cannot fully support the above-mentioned other CSI prediction functions. In this regard, this patent proposes a unified implementation method for AI-based CSI prediction services. Based on the same set of signaling processes, it can realize the acquisition of CSI information required in the data collection, reasoning and monitoring processes required for various AI-based prediction functions.

[0102] The CSI prediction method and the method for monitoring CSI prediction results provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

[0103] First, let’s describe the nouns involved in this application:

[0104] AI unit / AI model

[0105] The AI ​​unit / AI model described in this application may also be referred to as an AI unit, an AI model, a machine learning (ML) model, an ML unit, an AI structure, an AI function, an AI feature, a machine learning model, a neural network, a neural network function, a neural network function, etc., or the AI ​​unit / AI model may also refer to a processing unit that can implement specific algorithms, formulas, processing procedures, capabilities, etc. related to AI, or the AI ​​unit / AI model may be a processing method, algorithm, function, module or unit for a specific data set, or the AI ​​unit / AI model may be a processing method, algorithm, function, module or unit running on AI / ML related hardware such as a graphics processing unit (GPU), a neural network processor (NPU), a tensor processing unit (TPU), an application-specific integrated circuit (ASIC), etc., and this application does not make specific limitations on this. Optionally, the specific data set includes the input and / or output of the AI ​​unit / AI model.

[0106] Optionally, the identifier of the AI ​​unit / AI model may be an AI model identifier, an AI structure identifier, an AI algorithm identifier, or an identifier of a specific data set associated with the AI ​​unit / AI model, or an identifier of a specific scenario, environment, channel feature, or device related to the AI / ML, or an identifier of a function, feature, capability, or module related to the AI / ML. This application does not specifically limit this.

[0107] CSI prediction involves the following process:

[0108] Data acquisition: refers to the process of obtaining data corresponding to the input or output of an AI unit. Data acquisition can be used for different purposes, such as training, reasoning, monitoring, selection, and updating of AI units.

[0109] Reasoning: refers to the process of running an AI unit and obtaining the output of the AI ​​unit.

[0110] Monitoring: refers to the process of evaluating the reasoning performance of AI units. This can be achieved in various ways, such as monitoring based on calculating the reasoning accuracy of AI units based on their output, monitoring based on the input / output distribution of AI units, and monitoring based on the communication performance of communication systems.

[0111] Referring to FIG. 2 , an embodiment of the present application provides a CSI prediction method. The method is performed by a terminal and includes:

[0112] Step 201: The terminal receives first configuration information from a network-side device;

[0113] Step 202: The terminal sends first CSI to the network side device according to the first configuration information;

[0114] Step 203: The terminal receives the first AI unit from the network-side device;

[0115] Step 204: The terminal performs CSI prediction through the first AI unit;

[0116] Among them, the first configuration information is used to configure the terminal to determine the first CSI and send the first CSI based on the first CSI reference signal (CSI Reference Signal, CSI-RS) on the target resource, that is, the first configuration information is used to inform the terminal of the relevant configuration of the first CSI-RS sending. The terminal can correctly receive the first CSI-RS according to the first configuration information. The first CSI-RS is used to collect training data for the first AI unit. The terminal determines the first CSI based on the first CSI-RS. The first CSI is used to generate training data for the first AI unit. Specifically, the number of first CSI-RSs sent by the network side device is multiple, and the corresponding terminal determines multiple CSIs based on the multiple first CSI-RSs. These CSIs constitute CSI samples, that is, one sample is obtained for one CSI-RS. A large number of samples are used as model training data for the network side device to train the first AI unit.

[0117] The target resources include at least one of time domain resources, frequency domain resources and spatial domain resources. Depending on the target resources, the terminal can feedback CSI for different resources, and then train AI units for different resources on the network side. Different AI units can predict different categories of CSI. For example, if the target resource is a time domain resource, the trained AI unit can be applied to CSI prediction of the time domain type. If the target resource is a frequency domain resource, the trained AI unit can be applied to CSI prediction of the frequency domain type. If the target resource is a spatial domain resource, the trained AI unit can be applied to CSI prediction of the frequency domain type.

[0118] The first AI unit in the embodiment of the present application can be used to implement channel state information related processing, such as CSI time domain prediction, CSI time domain interpolation, CSI frequency domain interpolation, CSI spatial domain interpolation, CSI frequency domain extrapolation / prediction, CSI spatial domain prediction / extrapolation, and a combination of the above multiple functions (such as CSI time domain and frequency domain joint prediction), etc.

[0119] The above-mentioned airspace resources can specifically be antennas, ports, etc. The embodiment of the present application does not limit the specific category of the airspace.

[0120] The first AI unit is an AI unit obtained by the network side device based on the first CSI training, that is, the AI ​​unit training is performed on the network side, utilizing the more powerful computing power on the network side for efficient training of the AI ​​unit.

[0121] In an embodiment of the present application, the network-side device provides the terminal with CSI-RS configuration information, and the terminal determines the first CSI based on the configuration information and sends it to the network-side device. The first CSI is used as training data to train the network-side to obtain a first AI unit. The network-side device sends the first AI unit to the terminal, and the terminal performs CSI prediction through the first AI unit. In this way, for various types of CSI prediction, it is only necessary to provide different CSI-RS configuration information to the terminal based on the above process, and the terminal feeds back the corresponding training data to the network-side device. The network side trains the corresponding AI unit based on the training data and sends it to the terminal. The terminal implements CSI prediction based on the AI ​​unit. Based on the same set of signaling processes, the data collection and reasoning processes required for various AI-based prediction functions can be implemented, which can greatly reduce signaling overhead, improve system resource utilization, and help improve system throughput.

[0122] In one possible implementation, the first configuration information includes at least one of the following:

[0123] (1) First time domain configuration information, used to indicate time information corresponding to the first CSI-RS and time difference information between adjacent first CSI-RSs;

[0124] Time domain configuration determines the time points at which the CSI-RS is used to measure CSI, as well as the time difference between the CSIs before and after each time point. Traditional CSI-RS are generally transmitted with equal periods in the time domain. CSI-RS for CSI prediction can be transmitted in clusters in the time domain. The CSI within each cluster is not uniformly periodic, but rather has a time domain pattern. Here, the CSI-RS of a cluster is used to obtain a single CSI prediction sample, which contains CSI at multiple time points. For example, a sample contains CSI at five time points, with the time difference between the CSIs at adjacent time points being 5ms. Alternatively, the first CSI may be at time 0, the second at +5ms, the third at +10ms, the fourth at +30ms, and the fifth at +35ms. Therefore, the time domain patterns of the CSI-RS within a cluster can be unequally spaced.

[0125] (2) first frequency domain configuration information, used to indicate frequency information corresponding to the first CSI-RS and frequency difference information between adjacent first CSI-RSs;

[0126] Frequency domain configuration is used to determine the frequency points at which the CSI-RS is used to measure CSI, as well as the frequency difference between the CSI before and after the frequency domain. Traditional CSI-RS are equally spaced in the frequency domain, but CSI-RS used for CSI prediction (especially CSI frequency domain prediction) can be unequally spaced. Therefore, it is necessary to indicate the frequency domain location of the CSI-RS or the frequency domain interval between the CSI-RS before and after the frequency domain.

[0127] (3) first spatial domain configuration information, used to indicate the spatial domain information corresponding to the first CSI-RS;

[0128] Taking the airspace as a port as an example, the port configuration is used to determine which ports the CSI-RS is used to measure CSI on. The case where the airspace is an antenna is similar to the case where the airspace is a port and will not be repeated.

[0129] (4) Sample quantity information, used to indicate the quantity of the first CSI;

[0130] The number of samples refers to the total number of samples that need to be collected.

[0131] (5) first mode information, used to indicate the mode in which the terminal sends the first CSI to the network-side device;

[0132] The terminal may provide feedback on the first CSI in two ways: immediate feedback (immediate feedback of a sample after the terminal generates one) and non-immediate feedback (feedback on a specific resource or specific data channel after the terminal accumulates a certain number of samples).

[0133] (6) first condition information, used to indicate the conditions that must be met when the terminal sends the first CSI to the network-side device;

[0134] The feedback condition for the terminal to feed back the first CSI refers to condition information that the samples used for feeding back CSI prediction must meet.

[0135] (7) A first identifier, used to indicate that the first CSI-RS is used to obtain training data for the first AI unit.

[0136] It can be called a functional attribute label, which indicates that the CSI-RS is a CSI-RS sent specifically for data collection by the first AI unit.

[0137] In a possible implementation manner, before sending the first CSI to the network-side device, the method further includes:

[0138] The terminal sends second configuration information to the network side device;

[0139] The terminal reports the data used to train the first AI unit, namely a series of CSI samples, to the network. A CSI sample contains CSI data at multiple times, frequencies, or ports. Prior to this, the terminal sends CSI sample configuration information to the network. This configuration information describes the content of the CSI samples to be reported later.

[0140] The second configuration information includes at least one of the following:

[0141] (1) Second time domain configuration information, used to indicate the time information corresponding to the first CSI and the time difference information between adjacent first CSIs;

[0142] The time domain configuration can be described by the timestamps of multiple CSIs in the time domain within a CSI sample and the time difference between adjacent CSIs in the time domain.

[0143] (2) second frequency domain configuration information, used to indicate frequency information corresponding to the first CSI and frequency difference information between adjacent first CSIs;

[0144] The frequency domain configuration can be described by the frequency stamps of multiple CSIs in the frequency domain within a CSI sample and the frequency difference between adjacent CSIs in the frequency domain.

[0145] (3) Second spatial domain configuration information, used to indicate the spatial domain information corresponding to the first CSI;

[0146] Taking the airspace as a port as an example, the port configuration is generally described by a set of port identifiers associated with a CSI sample. The case where the airspace is an antenna is similar to the case where the airspace is a port and will not be repeated here.

[0147] (4) A second identifier, used to indicate that the first CSI is used for training the first AI unit.

[0148] It can be called a functional attribute label, which indicates that the CSI is specifically used to report data collection or model training for the first AI unit.

[0149] In a possible implementation, the terminal receives the first AI unit from the network-side device, including:

[0150] The terminal receives a file of the first AI unit, input configuration information of the first AI unit, and output configuration information of the first AI unit from the network-side device;

[0151] The network side sends the file of the first AI unit to the terminal. The file of the first unit can be a file in the Open Neural Network Exchange (ONNX) format, a file in the PTH format, or other private or public formats, as well as the input configuration information and output configuration information of the first AI unit.

[0152] The input configuration information includes at least one of the following:

[0153] (1) Input dimension information;

[0154] What dimension of data is the input, such as a matrix with M rows and N columns;

[0155] (2) The relationship between input and CSI;

[0156] How to use CSI information to form the input of the first AI unit, and which CSI is placed at which input position of the first AI;

[0157] (3) The relationship between input and auxiliary information;

[0158] The auxiliary information may include at least one of the following:

[0159] Delay information, delay spread information, speed information, Doppler information, Doppler spread information, channel time domain correlation information, channel frequency domain correlation information, perception information, etc.

[0160] The output configuration information includes at least one of the following:

[0161] (1) Output dimension information;

[0162] What dimension of data is output, such as a matrix with M rows and N columns;

[0163] (2) The relationship between output and CSI.

[0164] How to map the output of the first AI unit into CSI information.

[0165] In one possible implementation, the terminal performs CSI prediction by the first AI unit, including:

[0166] (1) The terminal receives a second CSI-RS from the network-side device;

[0167] (2) The terminal determines the second CSI based on the second CSI-RS;

[0168] (3) The terminal inputs the second CSI into the first AI unit and outputs the predicted CSI based on the file, input configuration information, and output configuration information of the first AI unit.

[0169] In the inference phase, the network side device sends a second CSI-RS to the terminal. The second CSI-RS can be called the CSI-RS in the inference phase. The terminal determines the second CSI based on the second CSI-RS, and uses the second CSI as input to predict the CSI using the first AI unit.

[0170] In one possible implementation, the method further includes:

[0171] The terminal receives first information from the network side device;

[0172] The first information includes at least one of the following:

[0173] (1) Single inference start time information of the first AI unit;

[0175] (3) The maximum time information of a single inference of the first AI unit; the terminal side is required to complete the inference of a single first AI unit within this time.

[0176] (4) CSI reporting time information: The terminal is required to report the CSI report at this time.

[0177] The network side sends the timeline requirement information of the first AI unit as described in (1) to (4) above to the terminal side, so that the terminal can clearly understand the time requirement for CSI prediction through the first AI unit.

[0179] Step 301: The network side device sends first configuration information to the terminal;

[0184] It should be noted that the network side device is the opposite side device that interacts with the terminal. The network side and the terminal side maintain the same understanding of the same information to ensure normal interaction of information on both sides. For the content of the interactive information, you can directly refer to the relevant description in the terminal side method above, and will not repeat it here.

[0185] In one possible implementation, the first configuration information includes at least one of the following:

[0186] First time domain configuration information is used to indicate time information corresponding to the first CSI-RS and time difference information between adjacent first CSI-RSs;

[0187] First frequency domain configuration information, used to indicate frequency information corresponding to the first CSI-RS and frequency difference information between adjacent first CSI-RSs;

[0192] The first identifier is used to indicate that the first CSI-RS is used to obtain training data of the first AI unit.

[0193] In a possible implementation, before the network-side device receives the first CSI from the terminal, the method further includes:

[0194] The network side device receives second configuration information from the terminal;

[0195] The second configuration information includes at least one of the following:

[0196] Second time domain configuration information, used to indicate time information corresponding to the first CSI and time difference information between adjacent first CSIs;

[0197] Second frequency domain configuration information, used to indicate frequency information corresponding to the first CSI and frequency difference information between adjacent first CSIs;

[0198] Second spatial domain configuration information, used to indicate spatial domain information corresponding to the first CSI;

[0199] The second identifier is used to indicate that the first CSI is used for training the first AI unit.

[0200] In one possible implementation, the network-side device sends the first AI unit to the terminal, including:

[0201] The network-side device sends the file of the first AI unit, the input configuration information of the first AI unit, and the output configuration information of the first AI unit to the terminal;

[0210] The network side device sends a second CSI-RS to the terminal;

[0211] The second CSI-RS is used by the terminal to perform CSI prediction through the first AI unit.

[0212] In one possible implementation, the method further includes:

[0213] The network side device sends first information to the terminal;

[0214] The first information includes at least one of the following:

[0215] Single inference start time information of the first AI unit;

[0216] Single inference completion time information of the first AI unit;

[0217] The maximum time for a single inference of the first AI unit;

[0218] CSI reporting time information.

[0219] 4 , an embodiment of the present application provides a method for monitoring CSI prediction results. The method is performed by a terminal and includes:

[0220] Step 401: The terminal receives a third CSI-RS from a network-side device;

[0221] Step 402: The terminal determines a third CSI according to the third CSI-RS;

[0222] Step 403: The terminal monitors the predicted CSI obtained by the first AI unit based on the third CSI;

[0223] The predicted CSI is the CSI predicted by the first AI unit based on the fourth CSI. The CSI-RS corresponding to the third CSI and the CSI-RS corresponding to the fourth CSI are located in different resource locations. The different resource locations can specifically be different time-frequency-space (time domain, frequency domain, spatial domain) resource locations. That is, in the monitoring phase, the CSI-RS used for monitoring and the CSI-RS used for inference are different CSI-RSs. Optionally, the third CSI can be referred to as a monitoring-specific CSI-RS, and the fourth CSI can be referred to as a CSI-RS for the inference phase.

[0224] The CSI-RS in the inference phase only needs to measure the CSI corresponding to the input of the first AI unit, while the CSI-RS in the monitoring phase also needs to measure the CSI corresponding to the output of the first AI unit. In other words, the time-frequency and spatial resource range of the CSI that needs to be measured in the monitoring phase is larger than that in the inference phase. The CSI in the monitoring phase may also require higher measurement accuracy, so it may be possible to reduce interference (such as neighboring cell interference) by adjusting the resource configuration of the CSI-RS.

[0225] In an embodiment of the present application, during the monitoring phase, the network-side device sends a CSI-RS to the terminal at a resource location different from that of the CSI-RS during the inference phase. The terminal monitors the results predicted by the AI ​​unit based on the CSI-RS during the monitoring phase to ensure the accuracy of the prediction results. Moreover, based on the same set of signaling processes, the monitoring processes required for various AI-based prediction functions can be implemented, which can greatly reduce signaling overhead, improve system resource utilization, and help improve system throughput.

[0226] In a possible implementation, when the third CSI is all CSI determined by the terminal according to the third CSI-RS, the fourth CSI is CSI determined by the terminal according to a CSI-RS different from the third CSI-RS;

[0227] In a possible implementation, when the third CSI is CSI determined by the terminal according to the first part of the CSI-RS in the third CSI-RS, the fourth CSI is CSI determined by the terminal according to the second part of the CSI-RS in the third CSI-RS.

[0228] The resource locations of the CSI-RS corresponding to the third CSI and the CSI-RS corresponding to the fourth CSI are different, which can be specifically divided into two cases:

[0229] Case 1: The third CSI is all CSI determined by the terminal based on the third CSI-RS. That is, the monitoring-dedicated CSI-RS is sent separately by the network-side device to the terminal. The network side specifically sends a CSI-RS for the terminal to monitor the AI ​​unit prediction results.

[0230] Case 2: The third CSI is the CSI determined by the terminal based on the first part of the CSI-RS in the third CSI-RS, and the fourth CSI is the CSI determined by the terminal based on the second part of the CSI-RS in the third CSI-RS. That is, a part of the third CSI-RS sent by the network side device to the terminal is used for inference of the AI ​​unit for CSI prediction, and the other part is used for monitoring the AI ​​unit to monitor the CSI prediction results.

[0231] In a possible implementation, the sequence settings of the CSI-RS corresponding to the third CSI and the CSI-RS corresponding to the fourth CSI are different, or the transmit powers of the CSI-RS corresponding to the third CSI and the CSI-RS corresponding to the fourth CSI are different.

[0232] The sequence setting for the monitoring-specific CSI-RS differs from that for the inference phase. Because the CSI time-frequency-spatial resource range required for measurement in the monitoring phase is larger than that in the inference phase, the sequence length also differs. Different measurement accuracy requirements also lead to different sequences (for example, the CSI-RS used in the inference phase is constructed based on the Zadoffchu sequence, while the CSI-RS used in the monitoring phase is constructed based on the m-sequence).

[0233] The transmission power of the dedicated monitoring CSI-RS is different from that of the CSI-RS in the inference phase. The power of the dedicated monitoring CSI-RS of the first AI unit can be higher than that of the CSI-RS in the inference phase.

[0234] Optionally, before the network device sends the first AI unit's dedicated monitoring CSI-RS to the terminal, the network device sends configuration information of the first AI unit's dedicated monitoring CSI-RS to the terminal. The configuration information mainly includes the time-frequency-space resource location or sequence setting of the first AI unit's dedicated monitoring CSI-RS.

[0235] In a possible implementation manner, the second CSI-RS has a third identifier, the third CSI-RS has a fourth identifier, and the third identifier is different from the fourth identifier.

[0236] The monitoring-specific CSI-RS and the CSI-RS used in the inference phase may have different identifiers, so that the terminal can determine which CSI-RS is used for inference and which CSI-RS is used for monitoring.

[0237] 5 , an embodiment of the present application provides a method for monitoring CSI prediction results. The method is performed by a network-side device and includes:

[0238] Step 501: The network side device sends a third CSI-RS to the terminal;

[0239] Among them, the third CSI-RS is used by the terminal to determine the third CSI, and the third CSIS is used by the terminal to monitor the predicted CSI output by the first AI unit. The predicted CSI is the CSI obtained by the first AI unit based on the fourth CSI prediction. The resource locations of the CSI-RS corresponding to the third CSI and the CSI-RS corresponding to the fourth CSI are different.

[0240] It should be noted that the network side device is the opposite side device that interacts with the terminal. The network side and the terminal side maintain the same understanding of the same information to ensure normal interaction of information on both sides. For the content of the interactive information, you can directly refer to the relevant description in the terminal side method above, and will not repeat it here.

[0241] In a possible implementation, when the third CSI is all CSI determined by the terminal according to the third CSI-RS, the fourth CSI is CSI determined by the terminal according to a CSI-RS different from the third CSI-RS;

[0242] When the third CSI is CSI determined by the terminal based on the first part of the third CSI-RS, the fourth CSI is CSI determined by the terminal based on the second part of the third CSI-RS.

[0243] In a possible implementation, the sequence settings of the CSI-RS corresponding to the third CSI and the CSI-RS corresponding to the fourth CSI are different, or the transmit powers of the CSI-RS corresponding to the third CSI and the CSI-RS corresponding to the fourth CSI are different.

[0244] In a possible implementation manner, the second CSI-RS has a third identifier, the third CSI-RS has a fourth identifier, and the third identifier is different from the fourth identifier.

[0245] In a possible implementation manner, the network-side device sends the third CSI-RS to the terminal, including:

[0246] (1) The network device stops sending the CSI-RS corresponding to the fourth CSI to the terminal, and sends the CSI-RS corresponding to the third CSI to the terminal;

[0247] (2) The network device sends the CSI-RS corresponding to the third CSI and the CSI-RS corresponding to the fourth CSI to the terminal at the same time.

[0248] There are two implementation methods for the first AI unit to monitor the dedicated CSI-RS:

[0249] (a) The CSI-RS in the inference phase is turned off. All CSI information required for monitoring by the first AI unit is obtained by measuring the dedicated CSI-RS for monitoring by the first AI unit.

[0250] (b) The CSI-RS used in the inference phase is maintained, and additional CSI information required for monitoring by the first AI unit is obtained by measuring the dedicated CSI-RS used for monitoring by the first AI unit. The additional CSI information refers to all CSI information required for monitoring by the first AI unit, excluding the CSI information obtained by measuring the CSI-RS used in the inference phase.

[0251] The application of the technical solution of this application is described with reference to specific application examples:

[0252] Generally speaking, the technical solutions of this application are all cases of obtaining another part of CSI from a part of CSI. The part can be viewed in the time domain, frequency domain, or spatial domain. The part can be continuous or discrete.

[0253] CSI time-domain prediction: The first AI unit uses historical CSI as input and outputs CSI at future times. For example, if the input is CSI at time slots [1, 2, 3, 4, 5], the output is CSI at time slots [6, 7, 8, 9].

[0254] CSI time-domain interpolation: The first AI unit uses multiple discrete CSIs as input and outputs other CSIs between the discrete CSIs. For example, if the input is CSI of time slots [1, 5, 9], the output is CSI of time slots [3, 7], CSI of time slots [1, 3, 5, 7, 9], CSI of time slots [2, 3, 4, 6, 7, 8], or CSI of time slots [1, 2, 3, 4, 5, 6, 7, 8, 9], and so on.

[0255] CSI frequency domain interpolation: Similar to time domain interpolation, multiple CSIs in the frequency domain are used as input to the first AI unit, and the output is the other CSIs between the CSIs in the frequency domain. For example, if the input is the CSI on the [1, 5, 9] resource blocks, the output is the CSI on the [3, 7] resource blocks, the CSI on the [1, 3, 5, 7, 9] resource blocks, the CSI on the [2, 3, 4, 6, 7, 8] resource blocks, or the CSI on the [1, 2, 3, 4, 5, 6, 7, 8, 9] resource blocks, and so on.

[0256] CSI spatial interpolation: Similar to temporal interpolation, this method uses multiple spatially discrete CSIs as input to the first AI unit and outputs the remaining CSIs between these spatially discrete CSIs. The spatial domain can be antennas, ports, etc. For example, if the input is CSI on ports [1, 3, 5, 7, 9], the output is CSI on the block of ports [2, 4, 6].

[0257] CSI frequency domain extrapolation / prediction: Similar to time domain prediction, the first AI unit takes a portion of CSI at the front or back of the frequency domain within a specified bandwidth as input and outputs CSI at another portion of the frequency domain within the specified bandwidth. For example, if the input is CSI for resource blocks [1, 2, 3, 4, 5], the output is CSI for resource blocks [6, 7, 8, 9].

[0258] CSI spatial prediction / extrapolation: Similar to temporal prediction, this method uses a portion of CSI located either forward or backward in the spatial domain as input to the first AI unit, and outputs CSI for another portion located further back or forward in the spatial domain. For example, if the input is CSI at ports [1, 2, 3, 4], the output is CSI at ports [5, 6, 7, 8].
