[0040] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0041] Artificial intelligence (AI)

[0042] In recent years, artificial intelligence research, represented by neural networks, has achieved remarkable results in many fields. Artificial intelligence will also play an important role in people's production and life for a long time to come.

[0043] As shown in Figure 2, the basic structure of a neural network consists of an input layer, hidden layers, and an output layer. The input layer receives data, the hidden layers process it, and the output layer produces the final result. In a neural network, each node represents a processing unit, or each node can be considered to simulate a neuron. Multiple neurons form a neural network layer, and multiple layers of information transmission and processing form the overall neural network.

[0044] With the continuous advancement of neural network research, deep learning architectures based on neural networks have been proposed in recent years. These architectures incorporate a large number of hidden layers, and feature learning is performed layer by layer through multi-hidden-layer neural networks, greatly improving the learning and processing capabilities of neural networks. Consequently, deep learning-based neural networks have been widely used in pattern recognition, signal processing, optimization and combination, anomaly detection, and other fields.

[0045] Digital pre-distortion (DPD)

[0046] Power amplifiers are essential components widely used in wireless communication systems. They have both linear and nonlinear regions. Generally speaking, they are designed to operate in the linear region. In other words, wireless communication systems expect the signal power range input to the amplifier to fall within its linear region to ensure output performance. If the amplifier operates in the nonlinear region, its power amplification function will be affected, resulting in actual output that does not meet the wireless communication system's expectations, leading to power loss.

[0047] DPD technology typically uses a DPD module working in conjunction with a power amplifier. For example, a DPD module can be integrated into the baseband signal processing process, compensating for power losses caused by the nonlinear distortion of the power amplifier. As shown in Figure 3, a DPD module can be deployed before the power amplifier. This DPD module can be considered the inverse function of the nonlinear power amplification of the power amplifier (as shown by the dotted line in Figure 3), thereby compensating for power deviations and losses caused by the nonlinear power amplification of the power amplifier.

[0048] In actual use, the operating characteristics of power amplifiers (such as nonlinearity) are often not fixed. Analysis of different devices, chipsets, environments, and configurations reveals that power amplifiers often exhibit varying operating characteristics. To address these characteristics, appropriate nonlinearity processing solutions are needed to match the amplifier's operating characteristics under varying conditions.

[0049] In practical engineering applications, identifying PA nonlinearity treatment solutions for these different conditions, and configuring, updating, and applying specific PA nonlinearity treatment solutions, are issues that need to be considered and addressed. For example, PAs used in different devices may exhibit different operating characteristics. Furthermore, the same PA may exhibit different operating characteristics when used in different frequency bands. Furthermore, the same PA may exhibit different operating characteristics under different operating bandwidths, operating voltages, and operating temperatures. To address these situations, different PA nonlinearity treatment solutions must be employed under different conditions to effectively address PA nonlinearity. Furthermore, when introducing multiple treatment solutions for different conditions, consideration may also be required regarding the configuration, updating, management, capability alignment, and prioritization of these solutions. Furthermore, when considering introducing PA nonlinearity treatment solutions as part of standardization within communication systems, providers and users of these solutions must have a consistent understanding of the applicable PA nonlinearity treatment solutions under different conditions.

[0050] To address at least one of the above problems, the embodiment of the present application is described in detail with reference to FIG4 .

[0051] FIG4 is a flow chart of a method for wireless communication provided in an embodiment of the present application. The method of FIG4 can be executed by a first device. The first device can be a terminal device or a network device.

[0052] 4 , in step S410 , the first device determines a first processing solution.

[0053] The first solution can be used to solve the first problem. The first problem can be associated with the operating characteristics of the power amplifier of the first device.

[0054] In some implementations, the operating characteristics of the power amplifier of the first device may refer to nonlinear characteristics of the power amplifier of the first device.

[0055] In some implementations, the first problem may refer to a nonlinear problem (or a nonlinear distortion problem) of a power amplifier of the first device.

[0056] In some implementations, the first problem may be a problem that causes nonlinear distortion in a power amplifier. That is, due to the first problem, when the transmission data of the first device enters the power amplifier for power amplification, the power amplifier may operate in a nonlinear region. The first problem is not necessarily a nonlinear distortion problem of the power amplifier; it may also be other problems that cause nonlinear distortion, or other problems derived from nonlinear distortion.

[0057] In some implementations, the cause of the power amplifier operating in the nonlinear region may be excessively high peak-to-average power ratio (PAPR) of transmission. Therefore, in some implementations, the first problem may be associated with the PAPR of transmission of the first device. For example, the first problem may be a poor PAPR indicator of transmission, or other effects caused by the poor PAPR indicator of transmission (i.e., derivative problems of the poor PAPR indicator).

[0058] The power amplifier operating in the nonlinear region may also be caused by a poor adjacent channel leakage ratio (ACLR) indicator of the transmission. Therefore, in some implementations, the first problem may be associated with the ACLR indicator of the transmission of the first device. For example, the first problem may be a poor ACLR indicator of the transmission, or other effects caused by the poor ACLR indicator of the transmission (i.e., derivative issues of the poor ACLR indicator).

[0059] The source of the power amplifier operating in the nonlinear region may be due to defects and limitations in the design of the transmission waveform. Therefore, in some implementations, the first problem may be associated with the transmission waveform of the first device. For example, the first problem may be a design issue with the transmission waveform. In another example, the first problem may be an adjustment issue with the transmission waveform of the first device.

[0060] In some implementations, the first processing scheme is used to match the operating characteristics of a power amplifier of the first device. For example, the first processing scheme can be used to match the nonlinear characteristics of the power amplifier of the first device. As an example, the first processing scheme can be used to compensate for nonlinear distortion of the power amplifier.

[0061] In some implementations, the first processing scheme is used to adjust the transmission waveform of the first device. The first processing scheme can adjust the transmission waveform of the first device so that the transmission waveform matches the operating characteristics of a power amplifier of the first device. The transmission waveform can be a transmission waveform associated with the power amplifier. For example, the first processing scheme can be used to adjust the transmission waveform input from the first device to the power amplifier. In another example, the first processing scheme can be used to adjust the transmission waveform output by the power amplifier.

[0062] In some implementations, the first processing scheme may include a pre-processing scheme before the power amplification (such as the DPD mentioned above).

[0063] In some implementations, the first processing scheme may include a post-processing scheme after the power amplifier (eg, a compensation scheme after nonlinear distortion occurs in the power amplifier).

[0064] In some implementations, the first processing scheme may include an internal processing scheme of the power amplifier, which may include, for example, a pre-processing scheme (pre-distortion compensation) and / or a post-processing scheme (compensation scheme after distortion) within the power amplifier.

[0065] In some implementations, the first processing solution may be associated with the first model (or the first function). For example, the first processing solution may be the first model (or the first function).

[0066] In some implementations, the first model can be an AI model or a machine learning (ML) model. Currently, most basic power amplifier compensation schemes (such as the DPD scheme mentioned above) use polynomial fitting to compensate for the nonlinear loss of the power amplifier. However, the use of polynomial fitting to fit and invert the nonlinear power amplifier function is relatively complex to implement, and the compensation effect is not good. Therefore, the use of AI / ML technology to perform nonlinear fitting of the power amplifier is expected to achieve better compensation effects.

[0067] In some implementations, the first processing scheme may be a neural network. For example, the first processing scheme may be a processing scheme consisting of an N-layer fully connected network. In another example, the first processing scheme may include an N-layer fully connected network, wherein the output portion of one or more layers is provided with an activation function.

[0068] In some implementations, the first processing scheme may be associated with the first condition or determined based on the first condition. In other words, the first processing scheme may perform one or more of the following operations under the first condition: matching the working characteristics of the power amplifier of the first device, adjusting the transmission waveform of the first device, and processing the first problem. As mentioned above, under different conditions, the working characteristics (such as nonlinear characteristics) of the power amplifier are different. The embodiment of the present application associates the first processing scheme with the first condition. Different first conditions can correspond to different first processing schemes, so that the embodiment of the present application can select a suitable processing scheme according to actual conditions, thereby improving the compensation effect of the nonlinear problem of the power amplifier. Taking the use of AI / ML models to process the nonlinear problem of the power amplifier under different conditions as an example, the first processing scheme mentioned above can be understood as an AI / ML model. Furthermore, multiple AI / ML models can be set for different conditions, and different AI / ML models compensate for the nonlinear problem of the power amplifier under different conditions.

[0069] In some implementations, the first processing solution is a first model (or a first function). Associating the first processing solution with the first condition may mean associating the first model (or the first function) with the first condition. Alternatively, the first model (or the first function) is determined based on the first condition. The first model may have a model identifier (or the first function may have a function identifier). Therefore, different first conditions may be associated with different first processing solutions based on the model identifier of the first model (or the function identifier of the first function).

[0070] As a more specific example, the first processing scheme is a neural network model, and different first conditions can determine different neural networks. Different neural networks can include different neural network structures and / or neural network parameters. Different neural network structures can, for example, refer to one or more differences in parameters such as the number of layers in the fully connected network, the number of neurons in each layer, and the type of activation function.

[0071] In some implementations, the association between the first condition and the first processing solution may be predefined by a protocol.

[0072] In some implementations, the association between the first condition and the first processing solution may be determined by the first device.

[0073] In some implementations, the association between the first condition and the first processing solution may be indicated by the second device, as shown in FIG5 .

[0074] In some implementations, the first condition and the first processing solution may be associated based on a first identifier. The first identifier may be an identifier of the first condition; alternatively, the first identifier may be an identifier that associates the first processing solution with the first condition. The following tables provide several examples of associating the first condition and the first processing solution based on the first identifier. See below for detailed descriptions.

[0075] The first condition mentioned above can be associated with any information that can affect the operating characteristics of the power amplifier (such as nonlinear characteristics). The following is a detailed example of the content of the first condition associated with the first processing solution.

[0076] In some implementations, the first condition is associated with a device type (e.g., a device model) of the first device. In other words, the first condition is determined based on the device type (e.g., a device model) of the first device. In other words, the association between the first processing scheme and the first condition is affected by the device type of the first device. For example, if the first device is a terminal device or a network device, different models of the terminal device or the network device may result in different operating characteristics of the power amplifiers used by them.

[0077] In some implementations, different types of first devices (such as different models of terminal devices or different models of network devices) can be associated with different first processing solutions. In other words, different types of first devices can use different first processing solutions to handle first problems (such as nonlinear problems of power amplifiers, transmission waveform problems, or other problems caused by the above problems). For example, a device type can be associated with a first processing solution. For another example, a device type set (the set can include multiple device types) can be associated with a first processing solution.

[0078] In some implementations, the device type of the first device and the first processing solution may be associated with each other based on a first identifier. The first identifier may be an identifier of the first condition; or the first identifier may be an identifier that associates the first processing solution with the device type, as shown in Table 1.

[0079] Table 1

[0080] As an example, if the first device is device A, model A (or function A) can be used to process the nonlinear problem of the power amplifier of device A (or, model A can be used to pre-process or post-process the power amplifier of device A, or to process the data and waveform of device A to adapt to the working characteristics of the power amplifier of device A); similarly, if the first device is device B, model B (or function B) can be used to process the nonlinear problem of the power amplifier of device B (or, model B can be used to pre-process or post-process the power amplifier of device B, or to process the data and waveform of device B to adapt to the working characteristics of the power amplifier of device B).

[0081] In some implementations, the first condition is associated with the power amplifier type (e.g., power amplifier model or power amplifier batch) of the first device. In other words, the first condition is determined based on the power amplifier type of the first device. The association between the first processing solution and the first condition may be affected by the power amplifier type of the first device.

[0082] For example, the operating characteristics (such as nonlinear characteristics) of different types of power amplifiers may be different, and different first processing schemes (such as AI / ML models) can be used to match the operating characteristics of the power amplifier.

[0083] For example, the working characteristics (such as nonlinear characteristics) of different types of power amplifiers may be different, and different first processing solutions (such as AI / ML models) can be used to deal with the first problem (such as the nonlinear problem of the power amplifier, the transmission waveform problem, or other problems caused by the above problems).

[0084] Taking the first processing solution as an example, a first model (such as an AI / ML model) can be used to handle the nonlinearity of a class of power amplifiers. For another example, a first model can be used to handle the nonlinearity of multiple types of power amplifiers (multiple types can be referred to as a type set).

[0085] In some implementations, the power amplifier type (or set of power amplifier types) of the first device and the first processing solution may be associated based on a first identifier. The first identifier may be an identifier of the first condition; or the first identifier may be an identifier that associates the first processing solution with the power amplifier type, as shown in Table 2.

[0086] Table 2

[0087] In some implementations, the first condition is associated with an operating frequency band (or type of operating frequency band) of the first device. In other words, the first condition is determined based on the operating frequency band of the first device. In other words, the association between the first processing solution and the first condition is affected by the operating frequency band of the first device.

[0088] For example, the operating characteristics (such as nonlinear characteristics) of power amplifiers in different frequency bands may be different, and different first processing schemes (such as AI / ML models) can be used to match the operating characteristics of the power amplifier.

[0089] For example, the operating characteristics (such as nonlinear characteristics) of power amplifiers in different frequency bands may be different, and different first processing solutions (such as AI / ML models) can be used to deal with the first problem (such as the nonlinear problem of the power amplifier, the transmission waveform problem, or other problems caused by the above problems).

[0090] Taking the first processing solution as an example, a first model (which can be an AI / ML model) can be used to process the nonlinearity of a power amplifier corresponding to a single operating frequency band. For another example, a first model can be used to process the nonlinearity of power amplifiers corresponding to multiple operating frequency bands (multiple frequency bands can be referred to as a frequency band set).

[0091] In some implementations, the operating frequency band (or set of operating frequency bands) of the first device and the first processing solution may be associated based on a first identifier. The first identifier may be an identifier of the first condition; or the first identifier may be an identifier that associates the first processing solution with the operating frequency band, as shown in Table 3.

[0092] Table 3

[0093] In some implementations, the first condition is associated with the operating bandwidth (or type of operating bandwidth) of the first device. In other words, the first condition is determined based on the operating bandwidth of the first device. In other words, the association between the first processing solution and the first condition is affected by the operating bandwidth of the first device.

[0094] For example, the operating characteristics (such as nonlinear characteristics) of power amplifiers operating at different bandwidths may be different, and different first processing solutions (such as AI / ML models and functions) can be used to match the operating characteristics of the power amplifier.

[0095] For example, the operating characteristics (such as nonlinear characteristics) of power amplifiers operating at different bandwidths may be different. Different first processing solutions (such as AI / ML models and functions) can be used to deal with the first problem (such as the nonlinear problem of the power amplifier, the transmission waveform problem, or other problems caused by the above problems).

[0096] Taking the first processing solution as an example, a first model (which can be an AI / ML model) can be used to process the nonlinearity of a power amplifier corresponding to a single operating bandwidth. For another example, a first model can be used to process the nonlinearity of power amplifiers corresponding to multiple operating bandwidths (multiple bandwidths can be referred to as a bandwidth set).

[0097] In some implementations, the operating bandwidth (or operating bandwidth set) of the first device and the first processing solution may be associated based on a first identifier. The first identifier may be an identifier of the first condition; or the first identifier may be an identifier that associates the first processing solution with the operating bandwidth, as shown in Table 4.

[0098] Table 4

[0099] In some implementations, the first condition is associated with the power level (or power type) of the first device. In other words, the first condition is determined based on the power level of the first device. In other words, the association between the first processing scheme and the first condition is affected by the power level of the first device. For example, the power amplifiers used at different power levels may be different, resulting in different operating characteristics (non-linear characteristics) of the power amplifiers at different power levels. For example, at a first power level (such as a high power level), the operating characteristics (non-linear characteristics) of the power amplifier are the first characteristics; at a second power level (such as a low power level), the operating characteristics (non-linear characteristics) of the power amplifier are the second characteristics.

[0100] In some implementations, the operating characteristics (such as nonlinear characteristics) of power amplifiers of different power levels may be different, and different first processing schemes (such as AI / ML models) can be used to match the operating characteristics of the power amplifiers.

[0101] In some implementations, the operating characteristics (such as nonlinear characteristics) of power amplifiers of different power levels may be different, and different first processing solutions (such as AI / ML models) can be used to deal with the first problem (such as the nonlinear problem of the power amplifier, the waveform problem of the transmission, or other problems caused by the above problems).

[0102] Taking the first processing solution as an example, a first model (which can be an AI / ML model) can be used to process the nonlinearity problem of a power amplifier corresponding to one power level. For another example, a first model can be used to process the nonlinearity problem of power amplifiers corresponding to multiple power levels.

[0103] In some implementations, the power level of the first device and the first processing solution may be associated with each other based on a first identifier. The first identifier may be an identifier of the first condition; or the first identifier may be an identifier that associates the first processing solution with the power level, as shown in Table 5.

[0104] Table 5

[0105] In some implementations, the first condition is associated with the operating temperature of the first device. Alternatively, the first condition is determined based on the operating temperature of the first device. Alternatively, the association between the first processing solution and the first condition is affected by the operating temperature of the first device.

[0106] For example, the operating characteristics (non-linear characteristics) of the power amplifier are different at different operating temperatures, so different first processing schemes can be used to match the operating characteristics (such as non-linear characteristics) of the power amplifier.

[0107] For example, the working characteristics (non-linear characteristics) of the power amplifier are different at different working temperatures, and different first processing schemes can be used to deal with the first problem (such as the non-linear problem of the power amplifier, the waveform problem of the transmission, or other problems caused by the above problems).

[0108] Taking the first processing scheme as the first model (which can be an AI / ML model) as an example, at the operating temperature L, model L can be used to process the working characteristics of the power amplifier (such as nonlinear characteristics); at the operating temperature M, model M can be used to process the working characteristics of the power amplifier (such as nonlinear characteristics).

[0109] In some implementations, the operating temperature of the first device and the first processing solution may be associated with each other based on a first identifier. The first identifier may be an identifier of the first condition; or the first identifier may be an identifier that associates the first processing solution with the operating temperature, as shown in Table 6.

[0110] Table 6

[0111] In some implementations, the first condition is associated with the operating humidity of the first device. Alternatively, the first condition is determined based on the operating humidity of the first device. Alternatively, the association between the first processing solution and the first condition is affected by the operating humidity of the first device.

[0112] For example, under different working humidity conditions, the working characteristics (non-linear characteristics) of the power amplifier are different, so different first processing solutions can be used to match the working characteristics (such as non-linear characteristics) of the power amplifier.

[0113] For example, under different working humidity, the working characteristics (non-linear characteristics) of the power amplifier are different, and different first processing solutions can be used to deal with the first problem (such as the non-linear problem of the power amplifier, the transmission waveform problem, or other problems caused by the above problems).

[0114] Taking the first processing scheme as the first model (which can be an AI / ML model) as an example, under working humidity N, model N can be used to process the working characteristics of the power amplifier (such as nonlinear characteristics); under working humidity O, model O can be used to process the working characteristics of the power amplifier (such as nonlinear characteristics).

[0115] In some implementations, the operating humidity of the first device and the first processing solution may be associated with each other based on a first identifier. The first identifier may be an identifier of the first condition; or the first identifier may be an identifier that associates the first processing solution with the operating humidity, as shown in Table 7.

[0116] Table 7

[0117] In some implementations, the first condition is associated with an operating voltage of the first device. In other words, the first condition is determined based on the operating voltage of the first device. In other words, the association between the first processing solution and the first condition is affected by the operating voltage of the first device.

[0118] For example, under different operating voltages, the operating characteristics (non-linear characteristics) of the power amplifier are different, so different first processing schemes can be used to match the operating characteristics (such as non-linear characteristics) of the power amplifier.

[0119] For example, under different operating voltages, the operating characteristics (non-linear characteristics) of the power amplifier are different, and different first processing solutions can be used to deal with the first problem (such as the non-linear problem of the power amplifier, the transmission waveform problem, or other problems caused by the above problems).

[0120] Taking the first processing scheme as the first model (which can be an AI / ML model) as an example, under the working voltage P, model P can be used to process the working characteristics of the power amplifier (such as nonlinear characteristics); under the working voltage Q, model Q can be used to process the working characteristics of the power amplifier (such as nonlinear characteristics).

[0121] In some implementations, the operating voltage of the first device and the first processing solution may be associated with each other based on a first identifier. The first identifier may be an identifier of the first condition; or the first identifier may be an identifier that associates the first processing solution with the operating voltage, as shown in Table 8.

[0122] Table 8

[0123] In some implementations, the first condition is associated with the usage environment (or usage region, such as a cold region, a tropical region, a humid environment, or a dry environment) of the first device. In other words, the first condition is determined based on the usage environment of the first device. In other words, the association between the first processing solution and the first condition is affected by the usage environment of the first device.

[0124] For example, under different usage environments, the working characteristics (non-linear characteristics) of the power amplifier are different, so different first processing solutions can be used to match the working characteristics (such as non-linear characteristics) of the power amplifier.

[0125] For example, under different usage environments, the working characteristics (non-linear characteristics) of the power amplifier are different, and different first processing solutions can be used to deal with the first problem (such as the non-linear problem of the power amplifier, the transmission waveform problem, or other problems caused by the above problems).

[0126] In some implementations, the usage environment of the first device and the first processing solution may be associated with each other based on a first identifier. The first identifier may be an identifier of the first condition; or the first identifier may be an identifier that associates the first processing solution with the usage environment, as shown in Table 9.

[0127] Table 9

[0128] In some implementations, the first condition is associated with a data type of the first device (or a data type input to a power amplifier of the first device). In other words, the first condition is determined based on the data type of the first device. In other words, the association between the first processing solution and the first condition is affected by the data type of the first device.

[0129] In some implementations, the data type of the first device may be determined based on one or more of: modulation information corresponding to the data; encoding information corresponding to the data; and waveform information corresponding to the data.

[0130] For example, if the first device uses a different modulation scheme, coding scheme, or waveform, the data type processed by the power amplifier may differ. For example, if the first device uses a different modulation scheme, coding scheme, or waveform, the amount or proportion of data falling within the nonlinear operating region of the power amplifier may differ. In this case, different first processing schemes can be used to distinguish and process different data types.

[0131] As an example, the first processing scheme is a first model (such as an AI / ML model). If the first device adopts a modulation mode T (such as one or more of QPSK, 16QAM, 64QAM, 128QAM, 256QAM, etc.), model T can be used to process the working characteristics of the power amplifier (such as nonlinear characteristics); if the first device adopts a modulation mode U (such as one or more of 512QAM, 1024QAM, 2048QAM, 8192QAM, etc.), model U can be used to process the working characteristics of the power amplifier (such as nonlinear characteristics).

[0132] As another example, the first processing scheme is a first model (such as an AI / ML model). If the first device adopts encoding method T, model T can be used to process the working characteristics of the power amplifier (such as nonlinear characteristics); if the first device adopts encoding method U, model U can be used to process the working characteristics of the power amplifier (such as nonlinear characteristics).

[0133] In some implementations, the data type of the first device and the first processing solution may be associated with each other based on a first identifier. The first identifier may be an identifier of the first condition; or the first identifier may be an identifier that associates the first processing solution with the data type, as shown in Table 10.

[0134] Table 10

[0135] In some implementations, the first condition is associated with the PAPR / ACLR (PAPR / ACLR level or PAPR / ACLR attribute) of the signal (or data transmission) of the first device. Alternatively, the first condition is determined based on the PAPR / ACLR of the signal of the first device. Alternatively, the association between the first processing scheme and the first condition is affected by the PAPR / ACLR of the signal of the first device. Different PAPR / ACLR levels can be addressed using different first processing schemes.

[0136] In some implementations, the PAPR / ACLR of the signal of the first device may be associated with the first processing scheme based on a first identifier. The first identifier may be an identifier of the first condition; or the first identifier may be an identifier associating the first processing scheme with the PAPR / ACLR of the signal, as shown in Table 11.

[0137] Table 11

[0138] Among the factors influencing the association between the first processing solution and the first condition, the association between the first condition and the first processing solution can be formed based on a specific first condition. For example, different power amplifier types can be associated with different AI / ML nonlinear processing models (or functions). For another example, different power levels can be associated with different AI / ML nonlinear processing models (or functions).

[0139] Among the influencing factors of the association between the first processing scheme and the first condition listed above, the association between the first condition and the first processing scheme can also be formed based on multiple influencing factors. For example, different combinations can be formed based on device type, operating frequency band, and data type, and then different combinations can be associated with different AI / ML nonlinear processing models (or functions). For another example, different combinations can be formed based on the operating temperature, operating humidity, and operating voltage of the device, and then different combinations can be associated with different AI / ML nonlinear processing models (or functions).

[0140] The above describes in detail the content of the first condition or the factors affecting the first processing solution. The following describes in detail the method for determining the first processing solution with reference to the embodiments.

[0141] In some implementations, the first processing solution may be provided by the first device itself. Accordingly, step S310 may include: the first device determining a first condition; and the first device determining the first processing solution according to the first condition.

[0142] In some implementations, the first device determines the first condition itself.

[0143] In some implementations, as shown in FIG6 , determining the first condition by the first device may include or be replaced by: the first device may receive first information sent by the second device. The first information may be used to indicate the first condition (or a portion of the first condition). In other words, the first device determines the first condition based on the first information sent by the second device. The first information may be a type of target information sent by the second device to the first device (the target information is used to determine the first processing solution).

[0144] In some implementations, the first information indicates one or more of the following: information associated with the first condition; a first identifier associated with the first condition. That is, the first information can indicate the first condition by indicating one or more of the above information.

[0145] For example, when the second device indicates the first condition (or part of the first condition) through the first information, the content indicated by the first information may, for example, include one or more of the following information associated with the first condition: device type, power amplifier type, operating frequency band, operating bandwidth, power level, operating temperature, operating humidity, operating voltage, usage environment, data type (such as modulation method or waveform), PAPR level, ACLR level and other information.

[0146] For another example, when the second device indicates the first condition (or part of the first condition) through the first information, the content indicated by the first information may include, for example, the first identifier associated with the first condition.

[0147] The first identifier may be, for example, a first association identifier between the first condition and the first processing solution. Different first association identifiers indicate one or more of the aforementioned information, as well as different first processing solutions to which different information may be associated. For details, see Tables 1 to 11 or a combination of Tables 1 to 11 mentioned above.

[0148] The first identifier may be, for example, a first condition identifier. Different first condition identifiers are associated with one or more of the above information, and different information may be associated with different first processing solutions. For details, see Tables 1 to 11 or a combination of Tables 1 to 11 mentioned above.

[0149] In some implementations, after the first device determines the first processing solution, the first processing solution may be used, activated, or updated. For example, if the first processing solution is a first model (or first function), after the first device determines the model identifier (or function identifier) ​​of the first model, the first processing solution may be used, activated, or updated based on the determined model identifier (or function identifier). Furthermore, the first device may also download and train the corresponding first processing solution based on the model identifier (or function identifier).

[0150] In some implementations, the first processing solution may be indicated or provided by the second device. Accordingly, as shown in FIG7 , step S310 may include or be replaced by: the first device receives second information sent by the second device. The second information indicates or includes the first processing solution. The second information may be a type of target information (information used to determine the first processing solution) sent by the second device to the first device.

[0151] In some implementations, the second information may indicate a first model associated with the first processing solution. For example, the second device may indicate the first model through a model identifier, and the first model may be used to process the first problem mentioned above.

[0152] In some implementations, the second information may indicate a first function associated with the first processing solution. For example, the second device may indicate the first function through a function identifier, and the first function may be used to process the first problem mentioned above.

[0153] In some implementations, the second information may indicate a first data set. The first data set may be used to generate (or construct, or train) a first model or implement a first function. The first model or first function may be used to address the first problem mentioned above.

[0154] In some implementations, the second information may include model data of the first model associated with the first processing solution. That is, the second device may provide or transmit the first model to the first device. For example, the second information may include one or more of the following information: model structure information, model parameter information, quantization information, interface information, etc. of the first model.

[0155] In some implementations, the second information may include the first data set mentioned above. That is, the second device may transmit the first data set to the first device. The first device may generate (or construct, or train) a first model based on the first data set.

[0156] In some implementations, the second information may be used to indicate the first condition. For example, the second device indicates the first condition to the first device, and the first device may determine the first processing solution based on the association between the first condition and the first processing solution. The association between the first condition and the first processing solution may be agreed upon in a protocol, determined by the first device, or indicated by the second device to the first device.

[0157] In some implementations, the second information may be used to indicate the first identifier. The first identifier may be an identifier of the first condition; or the first identifier may be an identifier that associates the first processing solution with the first condition.

[0158] In some implementations, as shown in FIG8 , before the first device receives the second information sent by the second device, the first device may first send third information to the second device, where the third information indicates the first condition.

[0159] In some implementations, the third information indicates one or more of the following: information associated with the first condition; a first identifier associated with the first condition. That is, the third information can indicate the first condition by indicating one or more of the above information.

[0160] For example, when the first device indicates the first condition (or part of the first condition) through the third information, the content indicated by the third information may include, for example, one or more of the following information associated with the first condition: device type, power amplifier type, operating frequency band, operating bandwidth, power level, operating temperature, operating humidity, operating voltage, usage environment, data type (such as modulation method or waveform), PAPR level, ACLR level and other information.

[0161] For another example, when the first device indicates the first condition (or part of the first condition) through the third information, the content indicated by the third information may include, for example, the first identifier associated with the first condition.

[0162] The first identifier may be, for example, a first association identifier between the first condition and the first processing solution. Different first association identifiers indicate one or more of the aforementioned information, as well as different first processing solutions to which different information may be associated. For details, see Tables 1 to 11 or a combination of Tables 1 to 11 mentioned above.

[0163] The first identifier may be, for example, a first condition identifier. Different first condition identifiers are associated with one or more of the above information, and different information may be associated with different first processing solutions. For details, see Tables 1 to 11 or a combination of Tables 1 to 11 mentioned above.

[0164] In some implementations, referring to FIG9 , before the first device receives the second information sent by the second device, the first device may first send a fourth information to the second device. The fourth information may be used to indicate a first processing scheme supported by the first device. Further, in some implementations, the first processing scheme indicated or included in the second information may be one of the first processing schemes supported by the first device (it may be one of the first processing schemes supported by the first device, or a subset). The first device indicating a supportable first processing scheme to the second device helps to avoid the first processing scheme (such as an AI / ML model) indicated or transmitted by the second device being a first processing scheme that is not supported or unavailable by the first device. Therefore, through the interaction of the above-mentioned fourth information, capability alignment with the first device can be performed.

[0165] In some implementations, the first device may have multiple first processing schemes, and the first processing scheme used by the first device may be determined based on the priority of the multiple first processing schemes.

[0166] In some implementations, the priority of multiple first processing solutions possessed by the first device may be determined based on one or more of the following: whether the first processing solution is indicated or provided by the second device; the scope of use of the multiple first processing solutions; and the number of first conditions associated with each of the multiple first processing solutions.

[0167] In some implementations, when the second device indicates or provides the first processing solution, the first processing solution used by the first device is the first processing solution indicated or provided by the second device.

[0168] As an example, the second device is a network device and the first device is a terminal device. When the network device instructs or provides a first processing solution to the terminal device (for example, a model for processing a nonlinear power amplifier problem), the terminal device uses the first processing solution indicated or provided by the network device as the currently used first processing solution. In other words, if the terminal device already has another model for processing nonlinear power amplifier problems, and the network device also configures a new model for processing nonlinear power amplifier problems for the terminal device, the model configured by the network device is valid.

[0169] As another example, when the network device expects to control the cell-level or network-level power amplifier nonlinear processing scheme, or the waveform adjustment scheme, the network device can indicate or provide the first processing scheme to the terminal device (for example, through broadcast, system information block (SIB), radio resource control (RRC) message, RRC reconfiguration message). After the network device indicates or provides the first processing scheme to the terminal device, the terminal device uses the first processing scheme indicated or provided by the network device. Even if the terminal device itself has other first processing schemes in this case, the network device does not expect the terminal device to continue to use the other first processing schemes. The other first processing schemes mentioned here can be, for example, the first processing scheme at the terminal device level, or the default processing scheme, or the public first processing scheme.

[0170] In some implementations, when a second device indicates or provides a first processing solution, and the first device has a first processing solution other than the first processing solution indicated or provided by the second device, the first device uses the first processing solution other than the first processing solution indicated or provided by the second device. In other words, the first device does not use the first processing solution indicated or provided by the second device.

[0171] As an example, the second device is a network device and the first device is a terminal device. When the network device indicates or provides a first processing solution to the terminal device (for example, the network device indicates a power amplifier nonlinear problem processing model to the terminal device), if the terminal device itself has the ability to process the power amplifier nonlinear problem, for example, the terminal device already has the first processing solution (for example, a nonlinear problem processing model that is adapted to the terminal device's own power amplifier working characteristics), the terminal device does not use the first processing solution indicated or provided by the network device.

[0172] As another example, the network device provides a cell-level or network-level (e.g., broadcast) power amplifier nonlinear processing solution or waveform adjustment solution (e.g., AI / ML model), but this cell-level or network-level first processing solution does not take into account the differences between terminal devices, and the processing effect is average. In this case, the terminal device can continue to use the first processing solution at the terminal device level and not use the cell-level or network-level first processing solution configured by the network device.

[0173] In some implementations, when the first device has a dedicated first processing scheme and a universal (or public) first processing scheme, the first device uses the dedicated first processing scheme. The difference between the dedicated first processing scheme and the universal first processing scheme can be, for example, that the first condition associated with the dedicated first processing scheme is narrower or more specific than the first condition associated with the universal first processing scheme.

[0174] In some implementations, the first device is a terminal device, and the dedicated first processing scheme can be indicated or transmitted through an RRC message, a medium access control layer control element (MAC CE) or downlink control information (DCI); the general first processing scheme can be indicated or transmitted through a broadcast message, SIB or RRC message.

[0175] In some implementations, the first device uses a first processing solution with fewer associated first conditions among the multiple first processing solutions. Alternatively, the first device uses a first processing solution under a specific first condition, but does not use a common first processing solution (or a first processing solution with more associated conditions).

[0176] For example, if the first device has, is indicated, or is transmitted a first processing solution A associated with a specific device type, the first device uses the first processing solution A. If the first device also has, is indicated, or is transmitted a first processing solution B applicable to multiple device types or does not distinguish between device types, the first device does not use the first processing solution B.

[0177] For another example, if the first device has, is instructed to, or is transmitted a first processing solution A associated with a specific power amplifier type, the first device uses the first processing solution A. If the first device also has, is instructed to, or is transmitted a first processing solution B applicable to multiple power amplifier types or does not distinguish between power amplifier types, the first device does not use the first processing solution B.

[0178] For another example, if the first device has, is instructed to, or is transmitted a first processing solution A associated with a specific operating bandwidth, the first device uses the first processing solution A. If the first device also has, is instructed to, or is transmitted a first processing solution B applicable to multiple operating bandwidths or does not distinguish between operating bandwidths, the first device does not use the first processing solution B.

[0179] For another example, if the first device has, is instructed to, or is transmitted a first processing solution A associated with a specific operating frequency band, the first device uses the first processing solution A. If the first device also has, is instructed to, or is transmitted a first processing solution B applicable to multiple operating frequency bands or does not distinguish between operating frequency bands, the first device does not use the first processing solution B.

[0180] For another example, if the first device has, is instructed to, or is transmitted a first processing solution A associated with a specific power level, the first device uses the first processing solution A. If the first device also has, is instructed to, or is transmitted a first processing solution B applicable to multiple power levels or does not distinguish between power levels, the first device does not use the first processing solution B.

[0181] For another example, if the first device has, is instructed to, or is transmitted a first processing solution A associated with a specific operating temperature, the first device uses the first processing solution A. If the first device also has, is instructed to, or is transmitted a first processing solution B applicable to multiple operating temperatures or does not distinguish between operating temperatures, the first device does not use the first processing solution B.

[0182] For another example, if the first device has, is instructed to, or is transmitted a first processing solution A associated with a specific operating humidity, the first device uses the first processing solution A. If the first device also has, is instructed to, or is transmitted a first processing solution B applicable to multiple operating humidity levels or does not distinguish between operating humidity levels, the first device does not use the first processing solution B.

[0183] For another example, if the first device has, is instructed to, or is transmitted a first processing solution A associated with a specific operating voltage, the first device uses the first processing solution A. If the first device also has, is instructed to, or is transmitted a first processing solution B applicable to multiple operating voltages or does not distinguish between operating voltages, the first device does not use the first processing solution B.

[0184] For another example, if the first device has, is instructed to, or is transmitted a first processing solution A associated with a specific usage environment, the first device uses the first processing solution A. If the first device also has, is instructed to, or is transmitted a first processing solution B applicable to multiple usage environments or does not distinguish between usage environments, the first device does not use the first processing solution B.

[0185] For another example, if the first device has, is instructed to, or is transmitted a first processing solution A associated with a specific data type, the first device uses the first processing solution A. If the first device also has, is instructed to, or is transmitted a first processing solution B applicable to multiple data types or does not distinguish between data types, the first device does not use the first processing solution B.

[0186] For another example, if the first device has, is instructed to, or is transmitted a first processing solution A associated with a specific PAPR level, the first device uses the first processing solution A. If the first device also has, is instructed to, or is transmitted a first processing solution B applicable to multiple PAPR levels or does not distinguish between PAPR levels, the first device does not use the first processing solution B.

[0187] For another example, if the first device has, is instructed to, or is transmitted a first processing solution A associated with a specific ACLR level, the first device uses the first processing solution A. If the first device also has, is instructed to, or is transmitted a first processing solution B applicable to multiple ACLR levels or does not distinguish between ACLR levels, the first device does not use the first processing solution B.

[0188] In addition to the conditions listed above (such as a specific device type or a specific amplifier type), the specific first condition can also be a combination of the conditions listed above (such as a combination of a specific operating temperature, operating humidity and operating voltage).

[0189] In some implementations, as shown in FIG10 , the first device may further send fifth information to the second device. The fifth information may indicate one or more of the following: whether the first device uses the first processing scheme; the first processing scheme used by the first device. For example, the fifth information may indicate whether the first device uses the first processing scheme through 1-bit information. For another example, the fifth information may indicate the identifier of the scheme used by the first device (taking the first processing scheme as the first model as an example, the fifth information may indicate the model identifier of the first model). For example, when the first processing scheme is determined or used by the first device, or when the first processing scheme is indicated or transmitted by the second device, the first device indicates to the second device that the first processing scheme is used or indicates the first processing scheme specifically used by the first device, so that the second device can know that the first device has adopted the first processing scheme to process the first problem, thereby avoiding repeated processing by the second device causing transmission errors.

[0190] For example, the first device is a terminal device and the second device is a network device. If the terminal device determines that it uses an AI / ML model for the nonlinear problem of the power amplifier (or for adjusting the transmission waveform of the terminal device), the terminal device can report to the network device that the terminal device uses the first processing solution.

[0191] For another example, the first device is a terminal device and the second device is a network device. If the terminal device determines that it uses an AI / ML model for the nonlinear problem of the power amplifier (or for adjusting the transmission waveform of the terminal device), the terminal device can indicate to the network device the identifier of the first processing scheme used by the terminal device (such as the identifier or function identifier of the AI / ML model). Alternatively, the terminal device may also indicate part or all of the information associated with the first condition to the network device. For example, the terminal device may indicate the content of the first condition, or the first terminal device may indicate the first identifier associated with the first condition. The network device can use the above information to know whether the terminal device uses the first processing scheme, or can know which first processing scheme the terminal device specifically uses.

[0192] In some implementations, if the first device is a base station and the second device is a terminal device, the first device indicates or transmits certain information (such as the third information, the fourth information or the fifth information above) to the second device, and one or more of the following methods can be used: broadcast messages (such as master information block (MIB), SIB1, SIBx), RRC messages, MAC CE, DCI, downlink messages in random access procedures (such as message B (MsgB), message 2 (Msg2), message 4 (Msg4)), physical downlink control channel (physical downlink control channel, PDCCH), physical downlink shared channel (physical downlink shared channel, PDSCH), AI / ML dedicated downlink channel, and capability indication information of network devices.

[0193] In some implementations, if the first device is a terminal device and the second device is a base station, the second device indicates or transmits certain information (such as the first information or the second information above) to the first device, and can adopt one or more of the following methods: broadcast messages (such as MIB, SIB1, SIBx), RRC messages, MAC CE, DCI, downlink messages in random access procedures (such as MsgB, Msg2, Msg4), PDCCH, PDSCH, AI / ML dedicated downlink channels, and capability indication information of network devices.

[0194] In some implementations, if the first device is a terminal device and the second device is a network device, the first device indicates or transmits certain information (such as the third information, the fourth information or the fifth information above) to the second device, and can adopt one or more of the following methods: RRC message, uplink control information (uplink control information, UCI) message, uplink message in the random access process (such as message A (MsgA), message 3 (Msg3)), physical uplink control channel (physical uplink control channel, PUCCH), physical uplink shared channel (physical uplink shared channel, PUSCH), AI / ML dedicated uplink channel, and terminal device capability information.

[0195] In some implementations, if the first device is a terminal device and the second device is a base station, the second device indicates or transmits certain information (such as the first information or the second information above) to the first device, and can use one or more of the following methods: RRC message, UCI message, uplink message in the random access process (such as MsgA, Msg3), PUCCH, PUSCH, AI / ML dedicated uplink channel, and terminal device capability information.

[0196] Taking the first processing solution mentioned above as an AI / ML model, and the AI / ML model processing the nonlinear problem of the power amplifier as an example, based on the content described above, the embodiment of the present application is equivalent to providing a method for configuring, updating, aligning capabilities, and determining the use priority of the AI / ML-based power amplifier nonlinear processing solution. The association between different conditions (device type, power amplifier type, operating frequency band, operating bandwidth, power level, operating temperature, operating humidity, operating voltage, usage environment, data type, PAPR level, ACLR level) and AI / ML models (used to process the nonlinear problem of the power amplifier, or the PAPR problem of transmission, or the ACLR problem of transmission, or the waveform adjustment problem of transmission, or the waveform generation problem of transmission) is given, and the AI / ML model indication, priority management, capability alignment and other model usage or management solutions involved in the association are given, so as to ensure that in the wireless communication system, the power amplifier derivative problem (nonlinear problem) processing solution that best matches the current power amplifier and the power amplifier working characteristics can be used effectively on demand.

[0197] The method embodiment of the present application is described in detail above in conjunction with Figures 1 to 10. The device embodiment of the present application is described in detail below in conjunction with Figures 11 to 13. It should be understood that the description of the method embodiment corresponds to the description of the device embodiment.
