[0074] To facilitate understanding, the relevant technologies and concepts involved in the embodiments of this application will be introduced first.
[0075] I. Artificial Intelligence (AI)
[0076] Artificial intelligence (AI) has wide applications in various fields such as communications, healthcare, and education. Integrating AI into wireless communication networks to improve technical indicators such as throughput, latency, and user capacity is an important task for future wireless communication networks. AI modules can be implemented in various ways, such as neural networks, decision trees, support vector machines, and Bayesian classifiers. This application's embodiments mainly use a neural network as an example for illustration, but this does not constitute a limitation on the specific type of AI module.
[0077] Figure 2 shows a schematic diagram of a neural network, which includes an input layer (X1, X2, ..., X...). n The neural network consists of three layers: a hidden layer (Y), a hidden layer, and an output layer (Y). A schematic diagram of a neuron is shown in Figure 3, where: z = a1w1 + ... + a... k w k +…+a K w K +b;
[0078] Among them, a1, a2, ..., a k ... a K The input is w, where w is the weight (multiplicative coefficient), b is the bias (additive coefficient), and σ(.) is the activation function. Common activation functions include the sigmoid function, the hyperbolic tangent function, and the rectified linear unit (ReLU) (or linear rectified function).
[0079] The parameters of a neural network are optimized using gradient optimization algorithms. Gradient optimization algorithms are a class of algorithms that minimize or maximize an objective function (or 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(.). After obtaining the neural network 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), which is the loss function. The goal is to find suitable W and b to minimize the value of the loss function. The smaller the loss value, the closer the prediction result of the neural network model is to the reality.
[0080] Most common optimization algorithms are based on the error back propagation (BP) algorithm. The basic idea of the BP algorithm is that the learning process consists of two parts: forward propagation of the signal and backward propagation of the error. During forward propagation, the input sample is introduced from the input layer, processed layer by layer by the hidden layers, and then propagated to the output layer. If the actual output of the output layer does not match the expected output, the process transitions to the error back propagation stage. Error back propagation involves propagating the output error back to the input layer layer by layer through the hidden layers, distributing the error to all units in each layer, thus obtaining the error signal of each unit. This error signal serves as the basis for adjusting the weights of each unit. This process of adjusting the weights through forward and backward propagation is repeated continuously. This continuous adjustment of weights is 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 the predetermined number of learning iterations is reached.
[0081] Common optimization algorithms include gradient descent, stochastic gradient descent (SGD), mini-batch gradient descent, momentum method, Nesterov (named after the inventor, specifically stochastic gradient descent with momentum), adaptive gradient descent (Adagrad), adaptive learning rate adjustment (Adadelta), root mean square prop (RMSprop), and adaptive momentum estimation (Adam).
[0082] During error backpropagation, these optimization algorithms calculate the gradient based on the error / loss obtained from the loss function with respect to the current neuron, add the learning rate, previous gradients / derivatives / partial derivatives, etc., and then pass the gradient to the previous layer.
[0083] II. AI Units / AI Models

Alternatively, AI unit / AI model may be a processing method, algorithm, function, characteristic, module, or unit for a specific dataset. Alternatively, AI unit / AI model may be a processing method, algorithm, function, characteristic, module, or unit running on AI / ML related hardware such as Graphics Processing Unit (GPU), Neural Processing Unit (NPU), Tensor Processing Unit (TPU), or Application-Specific Integrated Circuit (ASIC). This application embodiment does not specifically limit this. Optionally, the specific dataset includes the input or output of the AI unit / AI model.

This application embodiment does not specifically limit this.
[0086] III. Techniques to Counteract Power Amplifier (PA) Nonlinearity
[0087] In the transmitter end of a wireless communication system, digital pre-distortion (DPD) of the power amplifier is a common technique. It aims to reduce the distortion of the output signal by introducing a nonlinear characteristic opposite to the amplifier's nonlinearity. The basic principle of pre-distortion is to place a pre-distortion processing module before the power amplifier. The combined effect of the pre-distortion processing module and the power amplifier linearizes the overall input-output characteristics, ensuring full utilization of the output power. Its block diagram is shown in Figure 4.
[0088] Where x(n) represents the system input signal, z(n) represents the system output signal, and y(n) represents the output of the predistortion processing module. Assuming the input-output transfer characteristic of the power amplifier is G() and the characteristic of the predistortion processing module is F(), then the predistortion processing principle can be expressed as:
[0089] The composite function of G() and F() is equal to L().
[0090] Linearization requires L() to satisfy: z(n)=L(x(n))=g·x(n);
[0091] In the formula, the constant g is the ideal "amplitude gain" of the power amplifier (g>1).
[0092] At the receiver end, the principle of receiver compensation for nonlinearity differs from that of digital predistortion. It uses the equalized symbol X to estimate the nonlinear interference signal and feeds it back to the equalization calculation module to eliminate nonlinear distortion.
[0093] Using a digital predistortion algorithm module deployed at the transmitter end to combat the nonlinear distortion of the power amplifier places high demands on the transmitter's algorithm. In addition, deploying it at the receiver end has limited effectiveness in combating the nonlinear distortion of the power amplifier.
[0094] IV. Radio Frequency Indicator Information
[0095] Radio frequency (RF) specifications may include at least one of the following:
[0096] Peak-to-average power ratio (PAPR) information;
[0097] Error Vector Magnitude (EVM) information;
[0098] Information on the Spectrum Emission Mask (SEM);
[0099] Adjacent Channel Leakage Ratio (ACLR) information.
[0100] The relevant technologies and concepts involved in the embodiments of this application have been introduced above. The data collection method provided by the embodiments of this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.
[0101] Referring to Figure 5, which is a flowchart of an implementation of a data collection method provided in this application, the method includes the following steps:
[0102] S510: The terminal receives the first information from the network-side device;
[0103] S520: The terminal collects data based on the first information;
[0104] The first piece of information includes at least one of the following:
[0105] Configuration information of the synchronization signal block;
[0106] Configuration information of the channel state information reference signal;
[0107] The first relevant information of the physical downlink shared channel or the physical downlink control channel;
[0108] The second relevant information of the demodulation reference signal of the physical downlink shared channel or physical downlink control channel;
[0109] The first indication information is used to indicate that the downlink transmission does not require hybrid automatic repeat request confirmation feedback;
[0110] The second indication information is used to indicate the first time window, in which downlink transmission does not require mixed automatic repeat request confirmation feedback.
[0111] Using the method provided in the embodiments of this application, the terminal receives first information from the network-side device. The first information may include at least one of the following: configuration information of the synchronization signal block, configuration information of the channel state information reference signal, first related information of the physical downlink shared channel or physical downlink control channel, second related information of the demodulation reference signal of the physical downlink shared channel or physical downlink control channel, first indication information, and second indication information. Based on the first information, data can be collected to train a model. The model is used to compensate for the nonlinear distortion of the power amplifier at the transmitter end, reduce the power back-off of the power amplifier, increase the transmit power of the transmitter, improve the efficiency of the power amplifier, and enhance network coverage.
[0112] In this embodiment of the application, the terminal may be the terminal 11 shown in FIG1, and the network-side device may be the network-side device 12 shown in FIG1, which may include access network device or core network device.
[0113] In this embodiment, during downlink transmission, the AI model can be introduced to the receiver side, such as being deployed on the terminal side. In one scenario, such as a power amplifier nonlinearity scenario, deploying the AI model on the receiver side can compensate for the nonlinear distortion of the power amplifier, effectively solving the problem caused by the nonlinear distortion of the power amplifier at the transmitter end, and helping to improve the efficiency of the transmitter's power amplifier. In another scenario, such as a smart receiver scenario, deploying the AI model on the receiver side can be used to implement related module functions such as channel estimation, equalization, symbol detection, and demapping at the receiver end.
[0114] Figure 6 shows a schematic diagram of a receiver processing nonlinear distortion based on an AI model. On the transmitter side, the signal generated by the data generator is transmitted after being processed by a digital-to-analog converter (DAC) and a power amplifier. On the receiver side, the received signal is processed by a low-noise amplifier (LNA), an analog-to-digital converter (ADC), and an AI model before reaching the data receiver.
[0115] In downlink transmission, the network-side device acts as the transmitter, sending data, while the terminal acts as the receiver, deploying an AI model to process the received signal to compensate for the impact of network-side nonlinear distortion. This application's embodiments primarily consider data collection schemes for terminal-side model processing, such as model training or model updates. To train the model, the terminal needs to collect a dataset (Y, X), where Y represents the data information received by the terminal, and X represents the data information sent by the network-side device, also known as tag information.
[0116] The network-side device can send first information to the terminal, which indicates downlink transmission-related information. The terminal receives the first information from the network-side device and collects data based on the first information.
[0117] The first information may include at least one of the following:
[0118] Configuration information for the Synchronization Signal and PBCH block (SSB); PBCH stands for Physical Broadcast Channel.
[0119] Configuration information for the Channel State Information-Reference Signal (CSI-RS);
[0120] The first relevant information of the Physical Downlink Shared Channel (PDSCH) or Physical Downlink Control Channel (PDCCH);
[0121] The second relevant information of the demodulation reference signal of the physical downlink shared channel or physical downlink control channel;
[0122] The first indication information is used to indicate that the downlink transmission does not require hybrid automatic repeat request confirmation feedback;
[0123] The second indication information is used to indicate the first time window, in which downlink transmission does not require mixed automatic repeat request confirmation feedback.
[0124] Optionally, if the first information includes configuration information of the synchronization signal block, the terminal can receive the synchronization signal block from the network-side device based on the first information and perform data collection based on the synchronization signal block.
[0125] Optionally, network-side devices can send or trigger the configuration information of synchronization signal blocks via downlink control information (DCI), so that all terminals can share the configuration information of synchronization signal blocks, reducing downlink transmission and saving resources.
[0126] Optionally, if the first information includes configuration information of the channel state information reference signal, the terminal can receive the channel state information reference signal based on the first information and perform data collection based on the signal state information reference signal.
[0127] Optionally, if the first information includes first related information of the physical downlink shared channel or the physical downlink control channel, the terminal may receive the physical downlink shared channel or the physical downlink control channel based on the first information, and perform data collection based on the physical downlink shared channel or the physical downlink control channel.
[0128] Optionally, if the first information includes the second relevant information of the demodulation reference signal of the physical downlink shared channel or the physical downlink control channel, the terminal may receive the physical downlink shared channel or the physical downlink control channel based on the first information, and collect data based on the demodulation reference signal (DMRS) of the physical downlink shared channel or the physical downlink control channel.
[0129] Optionally, if the first information includes the first indication information, the terminal determines the downlink transmission based on the first indication information. For example, if the physical downlink shared channel or the physical downlink control channel does not require Hybrid Automatic Repeat reQuest (HARQ-ACK) feedback, the terminal does not need to provide feedback on the downlink transmission when it receives the first indication information and is collecting data, which helps to reduce unnecessary feedback overhead.
[0130] Optionally, if the first information includes the second indication information, the terminal can determine the first time window based on the second indication information. The downlink transmission in the first time window does not require mixed automatic repeat request acknowledgment feedback. In this way, when the terminal receives the second indication information, it does not need to provide feedback on the downlink transmission during the data collection period in the first time window, which helps to reduce unnecessary feedback overhead.
[0131] Optionally, the second instruction information may include at least one of the following:
[0132] Information about the length of the first time window, such as the number of time slots in the first time window;
[0133] The starting position information of the first time window;
[0134] The end position information of the first time window.
[0135] The starting position information of the first time window may include at least one of the following:
[0136] The starting position at which the first message is received;
[0137] The first information consists of N symbols following the last symbol, where N is an integer greater than or equal to 0;
[0138] The first symbol of the physical downlink shared channel for the first information scheduling.
[0139] Based on at least one of the above-mentioned information included in the second indication information, a first time window can be defined so that the terminal does not perform mixed automatic repeat request confirmation feedback for downlink transmissions within the first time window.
[0140] In some embodiments of this application, the terminal can collect data based on a reference signal (RS), such as a channel state information reference signal.

This first relevant information can be used to schedule or configure the transmission of the PHS-SCL. The first relevant information may include a random number, and the terminal can generate the data to be transmitted by the network-side device based on this random number.
[0156] 2) First scheduling information for the Physical Downlink Shared Channel (PHSS). This first scheduling information is used to schedule the first PHSS and the second PHSS.

The network-side device can send initial transmission data for the fourth PHSS to the terminal. Based on the first information, the terminal can receive the initial transmission data for the fourth PHSS. The terminal can also send confirmation information for the Hybrid Automatic Repeat Request (HARQ) for the fourth PHSS to the network-side device. The network-side device receives the confirmation information from the terminal and sends second information to the terminal. This second information is used to schedule retransmissions of the fourth PHSS. The terminal obtains tag information based on the initial transmission data for the fourth PHSS. This can be understood as follows: the fourth scheduling information schedules the initial transmission of the fourth physical downlink shared channel. If the confirmation feedback for the hybrid automatic repeat request of the fourth physical downlink shared channel is confirmed, the terminal can receive the second information from the network-side device. The second information is used to schedule the retransmission of the fourth physical downlink shared channel, and the terminal considers the initial transmission data of the fourth physical downlink shared channel to be tag information.

This second related information may include peak-to-average power ratio (PAPR) information of the demodulation reference signal, such as whether it has the same order of magnitude as the PHS. Alternatively, the second related information may include usage information of the demodulation reference signal, such as whether the demodulation reference signal is used for data collection. The terminal receives the demodulation reference signal based on the second related information of the PHS or PHS demodulation reference signal, and performs data collection based on the demodulation reference signal, which helps improve data collection efficiency.
[0165] This application embodiment solves the transmitter nonlinearity problem by deploying an AI model on the terminal side.
