Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to an information transmission method, apparatus, terminal, network-side equipment, and storage medium. Background Technology

[0002] In wireless communication systems, if the power amplifier (PA) at the transmitter enters the saturation region, nonlinear distortion will occur, resulting in signal distortion. To improve the nonlinear distortion of the system, power back-off can be implemented to force the power amplifier to avoid entering the saturation region. While the power back-off mechanism can reduce signal nonlinear distortion, the peak-to-average power ratio (PAPR) of large-bandwidth Orthogonal Frequency Division Multiplexing (OFDM) waveforms will cause the power amplifier to operate at a large power back-off point, leading to lower power amplifier efficiency.

[0050] To facilitate understanding, the relevant technologies and concepts involved in the embodiments of this application will be introduced first.

[0051] I. Artificial Intelligence (AI)

[0052] 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.

[0053] Figure 2 The diagram shown illustrates a neural network, which includes an input layer (x1, X2, ..., X...). n The neural network consists of three layers: a hidden layer (Y), ... and an output layer (Y). A neural network is composed of neurons, and a schematic diagram of a neuron is shown below. Figure 3 As shown, where:

[0054] z = a1w1 + ... + a k w k +…+a K w K +b;

[0055] 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).

[0056] 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.

[0057] 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.

[0058] 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).

[0059] 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.

[0060] II. AI Units / AI Models

[0061] In this application embodiment, AI unit / AI model may also be referred to as AI unit, AI model, AI module, machine learning (ML) model, ML unit, ML module, AI structure, AI function, AI characteristic, neural network, neural network function, neural network functionality, etc. Alternatively, AI unit / AI model may also refer to a processing unit or processing module capable of implementing specific algorithms, formulas, processing flows, capabilities, etc. related to AI. 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.

[0062] Optionally, the identifier of an AI unit / AI model can be understood as an AI unit identifier, AI model identifier, AI module identifier, AI structure identifier, AI algorithm identifier, or the identifier of a specific dataset associated with an AI unit / AI model, or the identifier of a specific scenario, environment, region, cell, channel characteristics, or device related to AI / ML, or the identifier of a function, characteristic, capability, or module related to AI / ML. This application embodiment does not specifically limit this.

[0063] III. Techniques to Counteract Power Amplifier (PA) Nonlinearity

[0064] In wireless communication systems, digital pre-distortion (DPD) of power amplifiers is a common technique. It aims to reduce the distortion of the output signal by introducing a nonlinear characteristic opposite to that of the amplifier. 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 below. Figure 4 As shown.

[0065] 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:

[0066]

[0067] The composite function of G() and F() is equal to L().

[0068] Linearization requires L() to satisfy:

[0069] z(n) = L(x(n)) = g·x(n);

[0070] In the formula, the constant g is the ideal "amplitude gain" of the power amplifier (g>1).

[0071] 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.

[0072] 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.

[0073] IV. Radio Frequency Indicator Information

[0074] Radio frequency (RF) specifications may include at least one of the following:

[0075] Peak-to-average power ratio (PAPR) information;

[0076] Error Vector Magnitude (EVM) information;

[0077] Information on the Spectrum Emission Mask (SEM);

[0078] Adjacent Channel Leakage Ratio (ACLR) information.

[0079] The relevant technologies and concepts involved in the embodiments of this application have been introduced above. The information transmission 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.

[0080] See Figure 5 The diagram shown is an implementation flowchart of an information transmission method provided in this application embodiment. The method includes the following steps:

[0081] S510: The terminal sends first information to the network-side device. The first information is used to indicate the terminal's transmission status.

[0082] Alternatively, the terminal sends a second message to the network-side device, the second message being used to indicate the terminal's reception status;

[0083] Alternatively, the terminal sends third information to the network-side device, which is used to obtain the dataset.

[0084] Using the method provided in this application embodiment, the terminal sends first information to the network-side device, which indicates the terminal's transmission status; or sends second information to the network-side device, which indicates the terminal's reception status; or sends third information to the network-side device, which is used to acquire a dataset. When the terminal informs the network-side device of its transmission status, the network-side device can reconstruct the terminal's transmitted signal based on the terminal's transmission status, reducing power back-off caused by nonlinear distortion and improving the efficiency of the terminal's power amplifier. When the terminal informs the network-side device of its reception status, the network-side device is aware of the terminal's signal reconstruction capability and can perform downlink transmission based on the terminal's signal reconstruction capability, reducing power back-off caused by nonlinear distortion and improving the network coverage of the network-side device.

[0085] The terminal in this embodiment of the application may be Figure 1 The terminal 11 shown can be a network-side device. Figure 1 The network-side device 12 shown may include access network devices or core network devices.

[0086] In this embodiment, the AI ​​model can be deployed on the receiver side. For example, in uplink transmission, the AI ​​model can be deployed on the network-side device side, and in downlink transmission, it can be 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.

[0087] like Figure 6 The diagram shows 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.

[0088] In uplink transmission, the terminal acts as the transmitter, sending data, while the network side acts as the receiver, deploying an AI model to process the received signal and compensate for the impact of nonlinear distortion on the signal from the terminal side. 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 and compensate for the impact of nonlinear distortion on the signal from the network-side device. This application's embodiments primarily consider information transmission schemes for receiver-side model processing, such as model training or model updates.

[0089] In uplink transmission, the terminal acts as the transmitter, and the network-side device acts as the receiver. The network-side device can use an AI model to compensate for the transmitter's nonlinear distortion. The terminal can send first information to the network-side device, which indicates the terminal's transmission status to assist the network-side device in uplink reception and model processing, such as model design, deployment, training, inference, and updating. The network-side device receives the first information from the terminal and, based on this information, can perform model processing.

[0090] The first information may include at least one of the following:

[0091] 1) Information related to power amplifiers.

[0092] Optionally, the relevant information of the power amplifier may include at least one of the following:

[0093] Behavioral information of the power amplifier;

[0094] Threshold value of the power amplifier output signal.

[0095] The power amplifier's behavioral information can include its power supply model, which can be either envelope tracking (ET) or average power tracking (APT). Under these two power supply models, the AI ​​model used by the receiver to compensate for the power amplifier's nonlinear distortion differs. The terminal reports this power amplifier behavioral information to the network-side equipment, which helps the network-side equipment design and update the AI ​​model.

[0096] The threshold value of the power amplifier output signal can be the maximum value of the normalized power amplifier output signal. For AI models, if the input to the AI ​​model exceeds this threshold value, the AI ​​model's performance in handling nonlinear distortion will decrease. The terminal reports the threshold value of the power amplifier output signal to the network-side device, which can effectively assist the network-side device in determining the effective input range for model training and inference, thereby achieving better results in handling nonlinear distortion.

[0097] 2) Power-related information.

[0098] Optionally, power-related information may include at least one of the following:

[0099] Power level classification information;

[0100] Maximum power backoff information;

[0101] Maximum transmit power information;

[0102] Maximum transmission power variation information.

[0103] Understandably, different groups of power information correspond to different AI models. The terminal reports the power level classification information to the network-side equipment, which helps the network-side equipment design and update the AI ​​models.

[0104] The terminal reports the maximum power reduction information to the network-side device, which can tell the network-side device the power point on the terminal side. Based on this information, the network-side device can determine whether the AI ​​model needs to be retrained.

[0105] The terminal reports its maximum transmission power information to the network-side device. Based on this information, the network-side device can determine whether the terminal's maximum transmission power has changed. If the maximum transmission power has changed, it can be assumed that the terminal's power amplifier has undergone a state update and a new AI model is needed. The network-side device can then retrain the AI ​​model.

[0106] The terminal reports the maximum transmission power change information to the network-side device. Based on this information, the network-side device can determine the change in the terminal's maximum transmission power and assume that the terminal's power amplifier has undergone a state update, requiring a new AI model. The network-side device can then retrain the AI ​​model or select a new model.

[0107] 3) Information related to the signals sent by the terminal.

[0108] Optionally, the relevant information of the signal transmitted by the terminal may include at least one of the following:

[0109] Peak-to-average power ratio (PAPR) information of the signal transmitted by the terminal;

[0110] Indicator information of the signals transmitted by the terminal;

[0111] Port information for the terminal to send signals;

[0112] Modulation information of the signal transmitted by the terminal.

[0113] The peak-to-average power ratio (PAPR) information of the terminal's transmitted signal may include a PAPR threshold value, such as XdB. The terminal reports its PAPR information, and the network-side device uses this information to determine whether the PAPR meets certain conditions, such as being greater than or equal to the PAPR threshold. If the conditions are met, the AI ​​model can be activated.

[0114] The indicator information of the signal transmitted by the terminal may include at least one of the following:

[0115] Error vector amplitude information of the signal transmitted by the terminal;

[0116] The spectrum transmission template information of the signal transmitted by the terminal;

[0117] Information on the adjacent channel leakage power ratio of the signal transmitted by the terminal.

[0118] The terminal reports the indicator information of the transmitted signal to the network-side equipment, which helps the network-side equipment to classify and process the terminal. For example, the terminal reports signal indicators of a typical waveform configuration, which includes error vector amplitude information and adjacent channel leakage power ratio information. Considering that different terminals have different processing algorithms and output signal indicators, the network-side equipment can classify and process the terminal based on the indicator information of the signal transmitted by the terminal.

[0119] The terminal reports the port information of the signals it sends to the network-side device, which helps the network-side device determine which AI model to deploy or enable. For example, N Sounding Reference Signal (SRS) ports correspond to M AI models; for instance, two SRS ports may each correspond to two different AI models, or two SRS ports may correspond to the same AI model. Based on the port information of the signals sent by the terminal, the network-side device can determine which AI model to deploy or enable.

[0120] The terminal reports the modulation scheme information of its transmitted signal to the network-side device. Based on this information, the network-side device can determine whether an AI model needs to be enabled, or the modulation scheme required for the AI ​​model to handle nonlinear distortion, such as 64QAM, 256QAM, 512QAM, 1024QAM, and 4096QAM in Quadrature Amplitude Modulation (QAM). Considering that for some modulation schemes, such as pi / 2 binary phase shift keying (BPSK) and quadrature phase shift keying (QPSK), the transmitter can compensate for nonlinear distortion with simple preprocessing, achieving good reception performance without requiring the receiver to enable an AI model, the terminal's reporting of the modulation scheme information helps reduce unnecessary processing and improves receiver reception efficiency.

[0121] 4) Bandwidth information. For example, the frequency band numbers supported by the terminal. The terminal reports the bandwidth information to the network-side equipment, which can assist the network-side equipment in processing AI models, for example, supporting model processing on specific frequency bands.

[0122] 5) Multi-carrier operation information. For example, carrier information shared by a single model. The terminal reports multi-carrier operation information to the network-side equipment, which can assist the network-side equipment in deploying or enabling the required AI models.

[0123] 6) First model update information.

[0124] Optionally, the first model update information may include at least one of the following:

[0125] First-hand information on model updates;

[0126] Updated model information.

[0127] The terminal reports the first-time information of the model update to the network-side device. Based on this information, the network-side device can know the first-time information that the AI ​​model needs to be retrained, such as the first time length and the first time range.

[0128] The updated model information may include model index, model identifier, etc. The terminal reports the updated model information to the network-side device, which can then switch to the new AI model based on this information.

[0129] During uplink transmission, the terminal sends first information to the network-side device, indicating the terminal's transmission status. The first information includes at least one of the above-mentioned features, which helps the network-side device to know the terminal's transmission status, reconstruct the terminal's transmission signal based on the terminal's transmission status, perform model processing based on the first information, compensate for the nonlinear distortion of the power amplifier, reduce the power back-off caused by the nonlinear distortion of the terminal, and improve the utilization efficiency of the terminal's power amplifier.

[0130] In downlink transmission, the network-side device acts as the transmitter, and the terminal acts as the receiver. The terminal can use an AI model to compensate for the nonlinear distortion of the transmitter. The terminal can send second information to the network-side device, which indicates the terminal's reception status to assist the network-side device in downlink transmission. The network-side device receives the second information from the terminal and, based on this information, can perform downlink transmission. The second information can also be understood as the processing result information of the AI ​​model.

[0131] The second information may include at least one of the following: error vector amplitude tolerance information of the terminal's receiver and information indicating the error vector amplitude of downlink transmission. The error vector amplitude tolerance information of the receiver can be understood as the error vector amplitude tolerance that the receiver can handle. Optionally, the error vector amplitude tolerance information corresponds to a modulation and coding scheme (MCS). The information reported by the terminal to indicate the error vector amplitude of downlink transmission can directly indicate the error vector amplitude of downlink transmission.

[0132] In downlink transmission, the terminal acts as the receiver, and model training and inference are all performed on the terminal side. The terminal can report secondary information to the network-side device so that the network-side device is aware of the terminal's signal restoration capability. Downlink transmission is then performed based on the terminal's signal restoration capability, reducing power backoff caused by nonlinear distortion and improving the network coverage of the network-side device.

[0133] In downlink transmission, the network-side device acts as the transmitter, and the terminal acts as the receiver. The terminal can use an AI model to compensate for the nonlinear distortion of the transmitter. The terminal can send third-party information to the network-side device, which is used to obtain a dataset. The network-side device receives the third-party information from the terminal and performs downlink transmission based on it. The terminal receives downlink transmission data from the network-side device, obtains the dataset, and performs model processing based on the dataset.

[0134] Third information may include at least one of the following:

[0135] Data set related information;

[0136] Second model update information.

[0137] The dataset-related information may include dataset size information. The terminal reports the dataset-related information to the network-side device to request the network-side device to issue transmission signaling for model training. The dataset can be obtained through this transmission signaling. In addition, the dataset-related information can also assist the network-side device in allocating downlink transmission resources.

[0138] The second model update information can include information indicating a model update or second time information about the model update. The terminal monitors the performance of the AI ​​model; if it determines that the AI ​​model needs updating, it can report information indicating the model update and request the network-side device to issue transmission signaling for model training. The terminal reports the second time information about the model update to the network-side device, which can assist the network-side device in reverting to a working mode assuming no AI model processing during the model update period, thus ensuring downlink transmission performance and reducing unnecessary resource waste.

[0139] In some embodiments of this application, the first, second, or third information may be carried by at least one of the following signaling methods:

[0140] Radio Resource Control (RRC) signaling;

[0141] Signaling of the MAC Control Element (MAC CE) in the Media Access Control (MAC) layer;

[0142] Uplink Control Information (UCI) signaling.

[0143] The first, second, or third information can be carried by one of the aforementioned signaling methods, or different parts of the first information can be carried by different signaling methods, or different parts of the second information can be carried by different signaling methods, or different parts of the third information can be carried by different signaling methods.

[0144] This application's embodiments address the transmitter's nonlinear distortion problem by deploying an AI model on the receiver side. On one hand, in power-constrained scenarios, this helps increase the transmitter's transmission power, thereby improving transmission performance. On the other hand, it improves the efficiency of the transmitter's power amplifier, reduces the complexity of the processing algorithm, and thus enhances the transmitter's energy efficiency. The terminal's information reporting under this working mechanism proposed in this application's embodiments helps assist network-side devices in model training, inference, or scheduling.
