[0045] For ease of understanding, some content related to the embodiments of this application is described below:

[0046] Artificial intelligence has currently found wide applications in various fields. There are multiple implementation methods for the artificial intelligence (AI) module, such as neural networks, decision trees, support vector machines, Bayesian classifiers, etc. This application takes neural networks as an example for illustration, but does not limit the specific type of the AI module.

[0047] A schematic diagram of a neural network is as Figure 2 shown.

[0048] Among them, a neural network is composed of neurons, and a schematic diagram of a neuron is as Figure 3 shown. Where a1, a2, … aK are inputs, w is the weight (multiplicative coefficient), b is the bias (additive coefficient), and σ(.) is the activation function. Common activation functions include Sigmoid, tanh, ReLU (Rectified Linear Unit), etc.

[0049] The parameters of the neural network are optimized through an optimization algorithm. An optimization algorithm is a type of algorithm that can minimize or maximize the objective function (i.e., the loss function). And the objective function is often a mathematical combination of model parameters and data. For example, given data X and its corresponding label Y, a neural network model f(.) is constructed. According to the input x, the predicted output f(x) can be obtained, and the gap between the predicted value and the true value (f(x) - Y) can be calculated, which is the loss function. By finding the appropriate parameters W, b to minimize the value of the above loss function, the smaller the loss value, the closer the AI model is to the real situation.

[0050] Currently, common optimization algorithms are basically based on the error Back Propagation (BP) algorithm. The basic idea of the BP algorithm is that the learning process consists of two processes: the forward propagation of signals and the backward propagation of errors. During forward propagation, the input samples are input 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, it enters the stage of backward propagation of errors. The error backpropagation is to backpropagate the output error in a certain form through the hidden layer to the input layer layer by layer, and distribute the error to all units of each layer, so as to obtain the error signals of each layer of units. This error signal is used as the basis for correcting the weights of each unit. This process of adjusting the weights of each layer in the forward propagation of signals and the backward propagation of errors is carried out cyclically. The process of continuously adjusting the weights is also the learning and training process of the network. This process continues until the error of the network output is reduced to an acceptable level, or until a pre-set number of learning times is reached.

[0051] Generally speaking, according to different types of problems to be solved, the selected AI algorithms and adopted AI models are also different. Usually, the main method to improve the 5G network performance with the help of AI is to enhance or replace the existing algorithms or processing modules through neural network-based algorithms and AI models. In specific scenarios, neural network-based algorithms and AI models can achieve better performance than deterministic algorithms. Commonly used neural networks include deep neural networks, convolutional neural networks, and recurrent neural networks, etc. With the help of existing AI tools, the construction, training, and verification of neural networks can be realized.

[0052] The following will combine the accompanying drawings and elaborate on the CSI report sending method, device, terminal, and network-side device provided by the embodiments of the present application through some embodiments and their application scenarios.

[0053] See Figure 4 , Figure 4 which is a flowchart of a CSI report sending method provided by the embodiments of the present application. As Figure 4 shown, the CSI report sending method includes the following steps:

[0054] Step 101, the terminal obtains target adjustment information, where the target adjustment information is used to adjust the configuration of the channel state information (CSI) report, and the target adjustment information is determined based on a first artificial intelligence (AI) unit, and the first AI unit is used for CSI-related processing.

[0055] Step 102, the terminal sends a CSI report to the network-side device based on the target adjustment information.

[0056] Among them, the target adjustment information may include the adjusted information in the CSI report configuration; or may include the adjusted CSI report configuration; or may include the adjustment scheme of the CSI report; and so on. Any information that can be used to adjust the configuration of the CSI report can be used as the target adjustment information. The specific implementation of the target adjustment information is not limited in this embodiment.

[0057] Taking the target adjustment information including the adjusted information in the CSI report configuration as an example, the target adjustment information may include the adjustment information of the CSI feedback parameter, the adjustment information of the CSI feedback content, the adjustment information of the feedback type, the adjustment information of the codebook, the adjustment information of the time-domain behavior of the CSI feedback, or the adjustment information of the frequency-domain configuration of the CSI feedback; and so on.

[0058] In addition, the terminal sending a CSI report to the network-side device based on the target adjustment information may include the terminal determining an adjusted CSI report configuration based on the information adjusted in the CSI report configuration and sending the CSI report to the network-side device based on the adjusted CSI report configuration; or, it may include the terminal sending the CSI report to the network-side device based on the adjusted CSI report configuration; or, it may include the terminal determining an adjusted CSI report configuration based on the adjustment scheme of the CSI report and sending the CSI report to the network-side device based on the adjusted CSI report configuration.

[0059] It should be noted that the target adjustment information may be determined by the terminal based on the first AI unit; or it may be determined by the network-side device based on the first AI unit, and the network-side device sends the target adjustment information to the terminal.

[0060] Among them, the target adjustment information may be determined based on the output of the first AI unit; or, the target adjustment information may be determined based on the performance evaluation result of the first AI unit; the target adjustment information may be determined based on the monitoring result of the first AI unit; and so on, which are not limited in this embodiment. The monitoring result of the first AI unit may also be described as the model monitoring result of the first AI unit.

[0061] In one implementation manner, the target adjustment information may be determined based on the output of the first AI unit. Exemplarily, the first AI unit may output the target adjustment information. At this time, the first AI unit is a model specifically used for CSI report adjustment, and its output is the target adjustment information. For example, 20 CSI report adjustment schemes are pre-configured as candidate adjustment schemes. The current channel state information and the load condition may be used as the input of the first AI unit, and the first AI unit directly outputs one of the 20 CSI report adjustment schemes as the target adjustment information.

[0062] In one implementation manner, the target adjustment information may be determined based on the performance evaluation result of the first AI unit. Exemplarily, the first AI unit may be used for CSI prediction, CSI compression, CSI interpolation, or CSI extrapolation. The target adjustment information may be determined based on performance indicators such as the inference accuracy of the first AI unit evaluated by the performance evaluation result of the first AI unit. For example, when the performance evaluation result of the first AI unit indicates that the inference accuracy of the first AI unit is relatively high, the original configuration of reporting CSI periodically may be adjusted to reporting CSI non-periodically to reduce the overhead of CSI reporting.

[0063] In one implementation, the target adjustment information may be determined based on the monitoring result of the first AI unit. Exemplarily, the first AI unit may be used for CSI prediction, CSI compression, CSI interpolation, or CSI extrapolation. The monitoring result of the first AI unit may be the performance metrics of the communication system, such as throughput, block error rate, etc., statistically obtained after applying the output of the first AI unit to the communication system, or may be the monitoring result obtained based on the distribution information of the input of the first AI unit. For example, when the monitoring result of the first AI unit indicates that the performance metrics of the communication system are poor, the original configuration of reporting CSI periodically may be adjusted to reporting CSI aperiodically, reducing the overhead of CSI reporting.

[0064] In addition, the first AI unit may be used to implement CSI-related processing, such as CSI prediction, CSI compression, CSI interpolation, CSI frequency domain prediction or extrapolation, or CSI spatial domain prediction or extrapolation, etc. This embodiment does not limit the CSI-related processing. CSI interpolation may include CSI time domain interpolation, CSI frequency domain interpolation, or CSI spatial domain interpolation, etc.

[0065] In the embodiments of the present application, the AI unit (such as the first AI unit) may also be referred to as an AI model, an AI structure, etc., or the AI unit may also refer to a processing unit capable of implementing specific algorithms, formulas, processing flows, capabilities, etc. related to AI, or the AI unit may be a processing method, algorithm, function, module, or unit for a specific data set, or the AI unit may be a processing method, algorithm, function, module, or unit running on AI-related hardware such as GPU, NPU, TPU, ASIC, etc. The embodiments of the present application do not make specific limitations on this. Optionally, the specific data set includes the input and / or output of the AI unit.

[0066] Optionally, the identifier of the AI unit may be an AI model identifier, an AI structure identifier, an AI algorithm identifier, a functionality ID, a physical identifier, a logical identifier, a global identifier, a local identifier, or the identifier of the specific data set associated with the AI unit, or the identifier of the specific scenario, environment, channel characteristics, device related to the AI, or the identifier of the function, feature, capability, or module related to the AI. The embodiments of the present application do not make specific limitations on this.

[0067] This embodiment can be applied to communication systems with wireless AI functions such as 5.5G or 6G.

[0068] It should be noted that replacing the modules in the existing system with AI / ML methods can effectively improve the system performance. As Figure 5 shown, the historical CSI is input into the AI unit, and the AI unit analyzes the time domain change characteristics of the channel and outputs the future CSI. The corresponding system performance is asFigure 6 As shown Figure 6 Figure 6 shows the Normalized Mean Square Error (NMSE) when using AI to predict CSI at multiple future time points. It can be seen that there is a significant performance gain in CSI prediction compared to the non-prediction scheme. At the same time, different future moments for prediction will result in different achievable prediction accuracies.

[0069] It should be noted that after the terminal performs AI-based CSI prediction, CSI feedback (i.e., sending a CSI report to the base station) is still required. Since CSI changes over time differently in different mobile environments, the configuration information for CSI feedback also needs to be dynamically adjusted. The embodiment of the present application can achieve dynamic adjustment of the configuration information for CSI feedback through the target adjustment information.

[0070] In the related art, there is no association between the CSI report and CSI prediction, and the configuration of the CSI report can only be adjusted according to past or current environmental configurations or system performance. In the embodiment of the present application, the configuration of the CSI report can be adjusted based on the CSI prediction result or CSI prediction performance determined by the first AI unit. When the CSI prediction result or CSI prediction performance is good, the overhead of CSI feedback can be reduced.

[0071] In the embodiment of the present application, the terminal obtains target adjustment information, where the target adjustment information is used to adjust the configuration of the Channel State Information (CSI) report. The target adjustment information is determined based on a first Artificial Intelligence (AI) unit, and the first AI unit is used for CSI-related processing. The terminal sends a CSI report to the network-side device based on the target adjustment information. In this way, the terminal can send a CSI report through the configuration of the CSI report adjusted by the target adjustment information, which can improve the flexibility of sending the CSI report.

[0072] Optionally, the target adjustment information is determined based on at least one of the following:

[0073] The output of the first AI unit; the performance evaluation result of the first AI unit; the monitoring result of the first AI unit.

[0074] Optionally, before the terminal obtains the target adjustment information, the method further includes:

[0075] The terminal receives first information sent by the network-side device;

[0076] The first information includes at least one of the following:

[0077] First indication information for activating the first AI unit;

[0078] The second indication information for indicating whether the CSI report configuration is adjustable;

[0079] The adjustable information in the CSI report configuration.

[0080] Among them, the adjustable information in the CSI report configuration may include at least one of the following: CSI feedback parameters; CSI feedback content; feedback type; codebook; time-domain behavior of CSI feedback; frequency-domain configuration of CSI feedback.

[0081] In addition, the frequency-domain configuration of CSI feedback may include the frequency-domain granularity of the precoding matrix indicator PMI and the channel quality indicator CQI, etc.

[0082] In one implementation, when the second indication information indicates that the CSI report configuration is adjustable, the first information includes the second indication information and the adjustable information in the CSI report configuration.

[0083] In one implementation, the second indication information may be a label indicating whether the CSI report is adjustable, and the adjustable information in the CSI report configuration may be the adjustable CSI report configuration content.

[0084] In one implementation, when the network-side device activates the CSI prediction of the terminal, it sends the first information to the terminal, and the first information carries a label indicating whether the CSI report is adjustable, and the adjustable CSI report configuration content.

[0085] Exemplarily, the network-side device sends the first information to the terminal, and the first information is used to activate the first AI unit of the terminal. In addition to the first indication information for activating the first AI unit, the first information may also carry a label indicating whether the CSI report is adjustable. For example, if the field of the label indicating whether the CSI report is adjustable is set to 1, it means that the terminal can adjust the CSI report configuration, and if it is set to 0, it means that the terminal cannot adjust the CSI report configuration. In addition, when the label indicating whether the CSI report is adjustable characterizes that the terminal can adjust the CSI report configuration, the first information may further include the adjustable CSI report configuration content. It should be noted that the label indicating whether the CSI report is adjustable and the adjustable CSI report configuration content may also be sent by a separate signaling.

[0086] In this implementation, the terminal receives the first indication information sent by the network-side device for activating the first AI unit, so that the terminal can activate the first AI unit based on the first indication information, perform CSI-related processing through the first AI unit to obtain target adjustment information, and send a CSI report according to the configuration of the CSI report adjusted by the target adjustment information, which can improve the flexibility of sending CSI reports.

[0087] In this embodiment, the terminal receives second indication information sent by the network-side device for indicating whether the CSI report configuration can be adjusted, so as to support the network side to configure to allow the terminal to adjust the CSI report configuration or not to allow the terminal to adjust the CSI report configuration, which can improve the flexibility of CSI report configuration adjustment.

[0088] In this embodiment, the terminal receives the adjustable information in the CSI report configuration sent by the network-side device, so as to support the network side to configure the information of the CSI report configuration allowed to be adjusted by the terminal, which can improve the flexibility of CSI report configuration adjustment.

[0089] Optionally, before the terminal obtains the target adjustment information, the method further includes:

[0090] The terminal sends a first adjustment request or first adjustment suggestion information to the network-side device based on the first AI unit;

[0091] Wherein, the target adjustment information is determined based on the first AI unit, and the first adjustment request or first adjustment suggestion information;

[0092] The first adjustment request includes at least one of the following:

[0093] A request to adjust CSI feedback parameters; a request to adjust CSI feedback content; a request to adjust the feedback type; a request to adjust the codebook; a request to adjust the time-domain behavior of CSI feedback; a request to adjust the frequency-domain configuration of CSI feedback;

[0094] The first adjustment suggestion information includes at least one of the following:

[0095] Adjustment suggestion information for CSI feedback parameters; adjustment suggestion information for CSI feedback content; adjustment suggestion information for feedback type; adjustment suggestion information for codebook; adjustment suggestion information for the time-domain behavior of CSI feedback; adjustment suggestion information for the frequency-domain configuration of CSI feedback.

[0096] Wherein, the network-side device can send a feedback on the first adjustment request or first adjustment suggestion information to the terminal, and the terminal can determine the target adjustment information based on the feedback of the network-side device on the first adjustment request or first adjustment suggestion information. Exemplarily, the terminal can send a request to adjust the codebook to the network-side device, and the network-side device feeds back the adjusted codebook to the terminal, and the target adjustment information can include the adjusted codebook; or, the terminal can send adjustment suggestion information for the codebook to the network-side device, and the network-side device feeds back an agreement to the adjustment suggestion information, and the target adjustment information can include the codebook characterized by the adjustment suggestion information.

[0097] In one implementation, the terminal activates the first AI unit based on the first information, and sends a first adjustment request or first adjustment suggestion information for the CSI report to a network-side device (such as a base station) according to the output of the first AI unit, or the performance evaluation of the first AI unit, or the model monitoring result of the first AI unit. The first adjustment request may include at least one of the following:

[0098] CSI feedback parameter adjustment request; CSI feedback content adjustment request; feedback scheme or codebook setting adjustment request; CSI feedback time-domain behavior adjustment request; precoding matrix indicator (PMI) and channel quality indicator (CQI) frequency-domain granularity adjustment request;

[0099] The first adjustment suggestion information includes at least one of the following: a new CSI feedback parameter, or an adjustment scheme for the CSI feedback parameter; a new CSI feedback content, or an adjustment scheme for the CSI feedback content; a new feedback scheme or codebook setting, or an adjustment scheme for the feedback scheme or codebook setting; a new CSI feedback time-domain behavior or an adjustment scheme for the CSI feedback time-domain behavior; a new PMI and CQI frequency-domain granularity or an adjustment scheme for the PMI and CQI frequency-domain granularity.

[0100] In this implementation, the terminal sends a first adjustment request or first adjustment suggestion information to the network-side device based on the first AI unit; wherein, the target adjustment information is determined based on the first AI unit and the first adjustment request or first adjustment suggestion information; in this way, the terminal can send a first adjustment request or first adjustment suggestion information to the network-side device based on the output of the first AI unit, the performance evaluation result of the first AI unit, or the monitoring result of the first AI unit, and obtain the target adjustment information through the feedback of the network-side device, and then send the CSI report according to the configuration of the CSI report adjusted by the target adjustment information, which can improve the flexibility of sending the CSI report.

[0101] Optionally, the terminal obtains the target adjustment information, including:

[0102] The terminal determines the target adjustment information based on the first AI unit.

[0103] It should be noted that the terminal determines the target adjustment information based on the first AI unit, sends the CSI report to the network-side device based on the target adjustment information, and the terminal can also send the target adjustment information to the network-side device, so that the network-side device can know the adjustment of the CSI report configuration by the terminal.

[0104] In one implementation, the terminal sends a CSI report to the network-side device, along with a CSI report configuration or a CSI report adjustment scheme. For example, the terminal adjusts the format of the CSI report according to the output of the first AI unit, the performance evaluation result of the first AI unit, or the monitoring result of the first AI unit, and directly sends it, attaching the adjusted CSI report configuration or CSI report adjustment scheme when sending the CSI report.

[0105] In this implementation, the terminal determines target adjustment information based on the first AI unit, thereby supporting the terminal to determine target adjustment information based on the output of the first AI unit, the performance evaluation result of the first AI unit, or the monitoring result of the first AI unit, and then sending the CSI report through the configuration of the CSI report adjusted by the target adjustment information, which can improve the flexibility of sending the CSI report.

[0106] Optionally, the method further includes:

[0107] The terminal sends a second adjustment request or second adjustment suggestion information to the network-side device based on the target adjustment information;

[0108] Wherein, the second adjustment request or the second adjustment suggestion information is used to request an adjustment of at least one of the following:

[0109] Channel State Information Reference Signal (CSI-RS) type; CSI-RS time-domain configuration; CSI-RS frequency-domain configuration; CSI-RS port configuration.

[0110] Wherein, the second adjustment request may be a CSI-RS configuration adjustment request, and the second adjustment suggestion information may be a CSI-RS configuration adjustment suggestion.

[0111] In one implementation, the terminal sends a CSI-RS configuration adjustment request or a CSI-RS configuration adjustment suggestion to the network-side device, for adjusting at least one of the following:

[0112] CSI-RS type: such as periodic CSI-RS, semi-persistent CSI-RS, or aperiodic CSI-RS;

[0113] CSI-RS time-domain configuration: such as the period of periodic CSI-RS and semi-persistent CSI-RS, or the time slot offset of the CSI-RS time slot relative to the period edge, etc.;

[0114] CSI-RS frequency-domain configuration;

[0115] CSI-RS port configuration.

[0116] In this embodiment, the terminal sends a second adjustment request or second adjustment suggestion information to the network-side device based on the target adjustment information; wherein, the second adjustment request or the second adjustment suggestion information is used to request an adjustment of at least one of the following: CSI-RS type; CSI-RS time-domain configuration; CSI-RS frequency-domain configuration; port configuration of CSI-RS. In this way, the CSI-RS configuration can be made more adaptable to the configuration of the CSI report adjusted by the target adjustment information through the second adjustment request or the second adjustment suggestion information, thereby improving the CSI prediction effect.

[0117] Optionally, the method further includes:

[0118] The terminal receives first association configuration information sent by the network-side device;

[0119] wherein, the target adjustment information is determined based on the first AI unit and the first association configuration information;

[0120] The first association configuration information is used to indicate at least one of the following:

[0121] Periodic CSI-RS is associated with periodic CSI reporting;

[0122] Periodic CSI-RS is associated with semi-persistent CSI reporting;

[0123] Periodic CSI-RS is associated with aperiodic CSI reporting;

[0124] Semi-persistent CSI-RS is associated with periodic CSI reporting;

[0125] Semi-persistent CSI-RS is associated with semi-persistent CSI reporting;

[0126] Semi-persistent CSI-RS is associated with aperiodic CSI reporting;

[0127] Aperiodic CSI-RS is associated with periodic CSI reporting;

[0128] Aperiodic CSI-RS is associated with semi-persistent CSI reporting;

[0129] Aperiodic CSI-RS is associated with aperiodic CSI reporting.

[0130] Among them, the first association configuration information may include the association configuration between CSI-RS and CSI reports. The network-side device sends the association configuration between CSI-RS and CSI reports or the optional association configuration between CSI-RS and CSI reports to the terminal. The association between CSI-RS and CSI reports can be arbitrary and is not limited to the fixed combination of CSI-RS and CSI reports in 5G. Any type of CSI-RS can be associated with any type of CSI report, and their time domain, frequency domain, and port configurations can be different.

[0131] In this embodiment, the terminal receives the first association configuration information sent by the network-side device; among them, the target adjustment information is determined based on the first AI unit and the first association configuration information; in this way, the terminal can adjust the configuration of the CSI report considering the association configuration between CSI-RS and CSI reports, so that the adjusted configuration of the CSI report is adapted to the first association configuration information, thereby facilitating the terminal to send CSI reports based on the CSI obtained from CSI-RS.

[0132] Optionally, when the terminal sends a CSI report using the second association configuration information, the CSI report includes first report content and second report content, the first report content is obtained based on CSI-RS, and the second report content is obtained based on the first AI unit;

[0133] Among them, the second association configuration information is used to indicate at least one of the following:

[0134] Semi-persistent CSI-RS is associated with periodic CSI reports; Aperiodic CSI-RS is associated with periodic CSI reports; Aperiodic CSI-RS is associated with semi-persistent CSI reports.

[0135] Among them, the second association configuration information may include the association configuration between CSI-RS and CSI reports.

[0136] It should be noted that if the terminal adopts the association configurations of associating semi-persistent CSI-RS with periodic CSI reports, associating aperiodic CSI-RS with periodic CSI reports, and associating aperiodic CSI-RS with semi-persistent CSI reports, in addition to the content that can be directly obtained from CSI-RS in the CSI report reported by the terminal, other content can be obtained through the first AI unit. For example, only partial CSI in terms of time can be obtained from aperiodic CSI-RS. If the CSI report is periodic and there is no corresponding CSI-RS at its time point, CSI can be obtained by interpolation or prediction through the first AI unit and form a CSI report for reporting.

[0137] In this embodiment, when the terminal sends a CSI report using the second association configuration information, the CSI report includes first report content and second report content. The first report content is obtained based on CSI-RS, and the second report content is obtained based on the first AI unit. Thus, the terminal can obtain CSI through the first AI unit to supplement the CSI obtained based on CSI-RS. It should be noted that in the related art, the second association configuration information is not supported. By obtaining CSI through the first AI unit to supplement the CSI obtained based on CSI-RS, it is possible to support the second association configuration information through the first AI unit.

[0138] Optionally, the method further includes:

[0139] The terminal sends third association configuration information to the network device, and the third association configuration information is used to indicate the association configuration between the CSI-RS supported by the terminal and the CSI report;

[0140] Wherein, the target adjustment information is determined based on the first AI unit and the third association configuration information.

[0141] Among them, the third association configuration information may include the association configuration between CSI-RS and the CSI report. The terminal can send the optional association configuration between CSI-RS and the CSI report to the network device.

[0142] In one embodiment, the network device may determine target adjustment information based on the first AI unit and the third association configuration information and send the target adjustment information to the terminal; or, the network device may send a feedback on the first adjustment request or the first adjustment suggestion information to the terminal based on the third association configuration information, and the terminal may determine the target adjustment information based on the feedback from the network device on the first adjustment request or the first adjustment suggestion information. By way of example, the first adjustment request may be a request to adjust the time-domain behavior of CSI feedback. The network device may determine a periodic CSI feedback mode, a semi-persistent CSI feedback mode, or an aperiodic CSI feedback mode based on the association configuration between the CSI-RS supported by the terminal and the CSI report, and send the adjustment information on the time-domain behavior of CSI feedback to the terminal.

[0143] In this embodiment, the terminal sends third association configuration information to the network-side device, and the third association configuration information is used to indicate the association configuration between the CSI-RS supported by the terminal and the CSI report; wherein, the target adjustment information is determined based on the first AI unit and the third association configuration information, so that the terminal reports to the network side the association configuration between the CSI-RS supported by the terminal and the CSI report, enabling the network side to adjust the configuration of the CSI report considering the capabilities of the terminal, making the adjusted CSI report configuration adapt to the terminal capabilities, and thus facilitating the terminal to send CSI reports based on the CSI obtained from the CSI-RS.

[0144] Optionally, the method further includes:

[0145] The terminal sends second information on the resources of the CSI report configuration indicated by the network-side device, and the second information is not a CSI report;

[0146] The terminal sends second indication information to the network-side device;

[0147] Wherein, the second indication information is used to indicate at least one of the following:

[0148] CSI report skipping; CSI report omission; CSI report punching.

[0149] Wherein, the second indication information can be sent on the resources of the CSI report configuration indicated by the network-side device, or can be sent on other resources.

[0150] In one embodiment, the terminal sends second information on the resources of the CSI report configuration indicated by the network-side device, and attaches tags of CSI report skipping, CSI report omission, or CSI report punching to the second information. It should be noted that whether to send the second information on the resources of the CSI report configuration indicated by the network side can be determined by the output result of the first AI unit, the performance evaluation result of the first AI unit, or the monitoring result of the first AI unit.

[0151] In this embodiment, the terminal sends second information on the resources of the CSI report configuration indicated by the network-side device, and the second information is not a CSI report; the terminal sends second indication information to the network-side device; wherein, the second indication information is used to indicate at least one of the following: CSI report skipping; CSI report omission; CSI report punching. Thus, when reducing CSI feedback through the target adjustment information, the remaining resources of the CSI feedback can be utilized to send other information, improving the resource utilization rate.

[0152] Optionally, the method further includes:

[0153] The terminal receives third information sent by the network-side device, where the third information is used to indicate a triggering condition for the terminal to send a CSI report, and the triggering condition is determined based on a first AI unit;

[0154] Wherein, the target adjustment information includes the third information.

[0155] Wherein, the triggering condition for the network-side device to send a CSI report to the terminal includes a triggering condition determined based on the output result of the first AI unit, the performance evaluation result of the first AI unit, or the monitoring result of the first AI unit. For example, the first AI unit periodically outputs whether to report a CSI report, or the first AI unit outputs the time point for sending a CSI report.

[0156] In this embodiment, the terminal receives third information sent by the network-side device, where the third information is used to indicate a triggering condition for the terminal to send a CSI report, and the triggering condition is determined based on a first AI unit; wherein, the target adjustment information includes the third information. In this way, by using the third information to support the terminal in determining whether to send a CSI report or the time for sending a CSI report based on the output of the first AI unit, the performance evaluation result of the first AI unit, or the monitoring result of the first AI unit, the flexibility of sending a CSI report can be improved.

[0157] Optionally, the method further includes:

[0158] The terminal receives fourth information sent by the network-side device, where the fourth information is used to indicate releasing or deactivating a periodic CSI report, or indicating releasing or deactivating a semi-persistent CSI report;

[0159] Wherein, the target adjustment information includes the fourth information.

[0160] Wherein, the network-side device can obtain periodic CSI or semi-persistent CSI through the first AI unit and the aperiodic CSI report sent by the terminal; or, the network-side device can obtain periodic CSI through the first AI unit and the semi-persistent CSI report sent by the terminal.

[0161] In one embodiment, the network-side device can determine whether to send the fourth information to the terminal based on the output of the first AI unit, the performance evaluation result of the first AI unit, or the monitoring result of the first AI unit.

[0162] In one implementation, the network-side device sends an instruction to the terminal for releasing or deactivating periodic CSI reporting or semi-persistent CSI reporting. As a result, the terminal does not need to report CSI periodically or semi-persistently. The network-side device can obtain periodic CSI or semi-persistent CSI by interpolation or prediction based on the aperiodic CSI report of the terminal through a first AI unit; or the network-side device can obtain periodic CSI by interpolation or prediction based on the semi-persistent CSI report of the terminal through the first AI unit.

[0163] In this implementation, the terminal receives fourth information sent by the network-side device, where the fourth information is used to indicate releasing or deactivating periodic CSI reporting, or indicating releasing or deactivating semi-persistent CSI reporting; where the target adjustment information includes the fourth information. In this way, when the network-side device can obtain CSI based on the first AI unit, it indicates that the terminal does not need to report CSI periodically or semi-persistently, which can reduce the overhead of CSI feedback by the terminal.

For periodic CSI feedback, the time-domain behavior of CSI feedback may further include the feedback period and feedback time slot offset of periodic CSI feedback; for semi-persistent CSI feedback, the time-domain behavior of CSI feedback may further include the feedback period and feedback time slot offset of semi-persistent CSI feedback.

[0173] In one implementation, the frequency-domain configuration of CSI feedback may include the frequency-domain granularity of PMI and CQI, including at least one of the following: wideband or sub-band feedback, sub-band size, and the property of whether multiple sub-bands are continuously configured in the frequency domain.

[0175] CSI prediction; CSI compression; CSI interpolation; CSI extrapolation; outputting the target adjustment information.

[0176] The embodiments of this application describe the process of adjusting CSI reports and CSI-RS configurations after CSI prediction or other processing based on AI, and propose a new association relationship between CSI reports and CSI-RS, and use AI to supplement combinations that could not be supported in the previous 5G stage.

[0177] It should be noted that in the related art, there is no association between the CSI report and the CSI prediction. The configuration of the CSI report can only be adjusted according to the past or current environment configuration or system performance. The embodiments of the present application propose a method for adjusting the CSI report, which can adjust the configuration of the CSI report through the CSI prediction result or performance determined by the first AI unit, and can reduce the overhead of CSI feedback when the CSI prediction performance is good.

[0233] The following uses several specific embodiments to illustrate the CSI report sending method provided by the embodiments of the present application:

[0234] Embodiment 1:

[0235] The embodiments of the present application are mainly for AI-based CSI prediction. After CSI prediction, the sending configurations of CSI reports and CSI-RS can be adjusted, so as to reduce the overhead of CSI reporting and CSI-RS as much as possible.

[0236] Example 1: The network side configures periodic CSI, but the terminal does not report CSI reports as agreed.

[0237] Based on AI-based CSI prediction, it is determined that the current channel changes slowly. The original configuration of reporting CSI periodically can be adjusted to reporting CSI aperiodically, or puncturing or skipping on the periodically reported CSI, and transmitting other control signaling or data on the time-frequency-space resources where CSI was originally to be reported periodically.

[0238] Example 2: The network side configures aperiodic CSI-RS, but the terminal reports semi-persistent or periodic CSI reports.

[0239] AI-based CSI prediction uses the aperiodic CSI estimated using reference signals (i.e., CSI-RS) to further derive the CSI at other time points required for periodic or semi-persistent CSI reporting, in addition to the aperiodic CSI estimated from the reference signals, and performs periodic or semi-persistent CSI reporting.

[0240] Example 3: Adjust the content of the CSI report.

[0241] The network side configures the CSI report content as {CRI-RI-PMI-CQI}. After AI-based CSI prediction, it is determined that the change in CQI is very slow, so CQI is removed from the current CSI report.
