Usually, the uplink transmission capability of the terminal device, such as the transmission rate, is positively correlated with the actual transmit power of the terminal device, and the transmit power is the difference between the maximum transmit power supported by the terminal device and the maximum power backoff parameter. Adjust the maximum power back-off parameter according to the first power information, the second power information, and the third power information corresponding to the power level, so that a smaller The maximum power back-off parameter is used to increase the transmit power of the terminal equipment, thereby solving the problem of low transmission rate during uplink transmission.

The fallback parameter is adjusted to obtain a smaller maximum power fallback parameter under the premise of power amplifier reliability, so that the transmission power of the terminal device can be increased, and the problem of low transmission rate during uplink transmission can be solved.

Since the minimum value among the first power information, the second power information, and the third power information is the third power information, the adjusted maximum power backoff parameter is determined according to the adjustment parameter corresponding to the third power information and the maximum power backoff parameter, In this way, a smaller adjusted maximum power backoff parameter can be obtained, and the adjusted maximum power backoff parameter can also meet the requirements of the communication protocol and meet the reliability requirements of the power amplifier of the terminal equipment.

In this way, since the characteristic of DPD calibration is equal compression, according to the maximum difference value under the power level, the maximum power back-off parameter under the power level is adjusted, which can reduce the difference between the compression state difference values corresponding to each high-order modulation mode. The difference makes the corresponding compression state of each high-order modulation mode equal at the same power level, which improves the DPD calibration benefit and thus increases the uplink transmission rate.

Since there are differences in the peak-to-average ratio of signals corresponding to various high-order modulation methods, and the peak-to-average ratio of the signal is too large, causing the power amplifier to work in a nonlinear region, resulting in signal distortion. Therefore, in order to maintain the linearity of the power amplifier, the maximum power backoff parameter is adjusted according to the peak-to-average ratio corresponding to the maximum power backoff parameter, so that the adjusted maximum power backoff parameter can meet the requirements of the communication protocol and meet the Power amplifier reliability requirements of terminal equipment.

The external memory card communicates with the processor 110 through the external memory interface 120 to implement a data storage function. Such as saving music, video and other files in the external memory card.

The internal memory 121 may be used to store computer-executable program codes including instructions. The internal memory 121 may include an area for storing programs and an area for storing data. Wherein, the stored program area can store an operating system, at least one application program required by a function (such as a sound playing function, an image playing function, etc.) and the like. The storage data area can store data created during the use of the terminal device 100 (such as audio data, phonebook, etc.) and the like. In addition, the internal memory 121 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one magnetic disk storage device, flash memory device, universal flash storage (universal flash storage, UFS) and the like. The processor 110 executes various functional applications and data processing of the terminal device 100 by executing instructions stored in the internal memory 121 and/or instructions stored in a memory provided in the processor.

The SIM card interface 195 is used for connecting a SIM card.

The software system of the terminal device 100 may adopt a layered architecture, an event-driven architecture, a micro-kernel architecture, a micro-service architecture, or a cloud architecture. In the embodiment of the present invention, the Android system with a layered architecture is taken as an example to illustrate the software structure of the terminal device 100 .

Fig. 2 is a block diagram of the software structure of the terminal device 100 according to the embodiment of the present invention.

The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. Layers communicate through software interfaces. In some embodiments, the Android system is divided into four layers, which are, from top to bottom, the application program layer, the application program framework layer, the Android runtime (Android runtime) and the system library, and the kernel layer.

The application layer can consist of a series of application packages.

As shown in Figure 2, the application package may include applications such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, and short message.

The application framework layer provides an application programming interface (application programming interface, API) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions.

As shown in Figure 2, the application framework layer can include window managers, content providers, view systems, phone managers, resource managers, notification managers, and so on.

A window manager is used to manage window programs. The window manager can get the size of the display screen, determine whether there is a status bar, lock the screen, capture the screen, etc.

Content providers are used to store and retrieve data and make it accessible to applications. Data can include videos, images, audio, calls made and received, browsing history and bookmarks, phonebook, etc.

The view system includes visual controls, such as controls for displaying text, controls for displaying pictures, and so on. The view system can be used to build applications. A display interface can consist of one or more views. For example, a display interface including a text message notification icon may include a view for displaying text and a view for displaying pictures.

The phone manager is used to provide the communication function of the terminal device 100 . For example, the management of call status (including connected, hung up, etc.).

The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, and so on.

The notification manager enables the application to display notification information in the status bar, which can be used to convey notification-type messages, and can automatically disappear after a short stay without user interaction. For example, the notification manager is used to notify the download completion, message reminder, etc. The notification manager can also be a notification that appears on the top status bar of the system in the form of a chart or scroll bar text, such as a notification of an application running in the background, or a notification that appears on the screen in the form of a dialog window. For example, a text message is displayed in the status bar, a prompt sound is issued, the terminal device vibrates, and the indicator light flashes, etc.

Android Runtime includes core library and virtual machine. The Android runtime is responsible for the scheduling and management of the Android system.

The core library consists of two parts: one part is the function function that the java language needs to call, and the other part is the core library of Android.

The application layer and the application framework layer run in virtual machines. The virtual machine executes the java files of the application program layer and the application program framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

A system library can include multiple function modules. For example: surface manager (surface manager), media library (Media Libraries), 3D graphics processing library (eg: OpenGL ES), 2D graphics engine (eg: SGL), etc.

The surface manager is used to manage the display subsystem and provides the fusion of 2D and 3D layers for multiple applications.

The media library supports playback and recording of various commonly used audio and video formats, as well as still image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing, etc.

2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is the layer between hardware and software. The kernel layer includes at least a display driver, a camera driver, an audio driver, and a sensor driver.

The workflow of the software and hardware of the terminal device 100 will be exemplarily described below in conjunction with capturing and photographing scenes.

When the touch sensor 180K receives a touch operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes touch operations into original input events (including touch coordinates, time stamps of touch operations, and other information). Raw input events are stored at the kernel level. The application framework layer obtains the original input event from the kernel layer, and identifies the control corresponding to the input event. Take the touch operation as a touch click operation, and the control corresponding to the click operation is the control of the camera application icon as an example. The camera application calls the interface of the application framework layer to start the camera application, and then starts the camera driver by calling the kernel layer. Camera 193 captures still images or video.

In the fifth generation mobile communication technology (5th Generation Mobile Communication Technology, 5G), in the uplink transmission process, a high-order modulation method is required.

In order to maintain the linearity of the power amplifier, the uplink transmission of the terminal device 100 requires maximum power reduction (maximum power reduction, MPR). FIG. 3 is a diagram of an uplink transmission scenario provided by an embodiment of the present application. Since power backoff is required in the high-order modulation mode, as shown in FIG. The transmit power Pm is calculated based on the pre-configured target power and the pre-configured maximum power reduction (MPR) parameter, so as to use the calculated transmit power Pm to transmit the signal corresponding to the uplink data. The transmission of the signal corresponding to the uplink data is closely related to the radio frequency link of the terminal equipment. FIG. 4 is a schematic diagram of a radio frequency link of a terminal device provided by an embodiment of the present application. As shown in FIG. 4 , the radio frequency link of the terminal device 100 includes a radio frequency integrated circuit (RFIC), a power amplifier (poweramplifier, PA), a filter, and a radio frequency test socket (RFswitch); wherein, the radio frequency integrated circuit is connected to the power amplifier, and the power The amplifier is connected with the filter, and the filter is connected with the radio frequency test socket.

In this embodiment of the present application, the pre-configured target power is also referred to as preset target power. Preconfigured maximum power backoff (MPR) parameters are also referred to as preset maximum power backoff (MPR) parameters. In this embodiment of the application, the preset target power and preset MPR parameters of the terminal device 100 can be written into the non-volatile memory (non-volatile memory) of the terminal device 100 through the operating system of the terminal device 100 itself before leaving the factory. -volatile memory, NV). Exemplarily, after the working platform of the manufacturer of the terminal device 100 determines the preset target power and the preset MPR parameters of the terminal device 100, the determined preset target power and the preset MPR parameters are sent to the terminal device 100. Write a preset target power and a preset MPR parameter into the terminal device 100 through an operating system of the terminal device 100 . Optionally, after the terminal device 100 determines the preset target power and the preset MPR parameters of the terminal device 100, the preset target power and the preset MPR parameters are written into the terminal through the operating system of the terminal device 100. device 100.

In a possible implementation, the pre-configured target power Ptar on the terminal device 100 is configured according to the power value Ptarpc1 corresponding to the power level in the protocol, and the pre-configured maximum power backoff MPR on the terminal device 100 is based on the protocol maximum MPR configured. The agreement is, for example, a third generation partnership project (3rd generation partnership project, 3GPP) agreement.

Exemplarily, FIG. 5 is a schematic diagram of a configuration process of the target power Ptar in a possible implementation manner. As shown in FIG. 5 , the staff of the manufacturer of the terminal device 100 calculates Pmax1 for the radio frequency link budget of the terminal device 100 through the working platform. The working platform compares whether the power value Ptarpc1 corresponding to the power level of the terminal device 100 is less than Pmax1, and if so, sets the value of the preset target power Ptar as the value of Ptarpc1, and sets the preset value through the operating system of the terminal device 100. The target power Ptar is written into the non-volatile memory (non-volatile memory, NV) of the terminal device 100, if not, the value of the preset target power Ptar is set to the value of Pmax1, and the terminal device 100 The operating system of the system writes the preset target power Ptar into the NV of the terminal device 100 . where Pmax1 = Ppa-IL. Pmax1 is the steady-state maximum power allowed to be transmitted when the output port of the radio frequency test socket on the radio frequency link of the terminal device 100 is not calibrated. Ppa is the maximum steady-state power allowed at the output port of the power amplifier as defined in the device manual. IL is the power loss in the transmission process of the uplink data signal in the radio frequency link of the terminal device 100 after it is output from the power amplifier and before it is input to the radio frequency test socket. IL is also called insertion loss (insertion loss, IL). Ptarpc1 is the power value corresponding to the power level defined by the protocol. For example, according to the 3GPP agreement, the corresponding power value Ptarpc1 of power class PC2 (power class2) is 26dbm, and the corresponding power value Ptarpc1 of power class PC3 (power class3) is 24.5dbm.

For example, when Ptarpc1<Pmax1, the value of Ptarpc1 is written into the NV of the terminal device 100 as the value of the preset target power Ptar. When Ptarpc ≥ Pmax1, the value of Pmax1 is written into the NV of the terminal device as the value of the preset target power Ptar. In a possible implementation manner, the preset target power of the terminal device 100 is Ptar=min(Pmax1, Ptarpc1).

In a possible implementation manner, the MPR parameter preconfigured on the terminal device 100 is configured according to the maximum MPR of the protocol. For example, the pre-configured MPR parameters on the terminal device 100 are configured according to the maximum MPR corresponding to the power level, high-order modulation mode, and RB configuration mode in the 3GPP protocol.

Fig. 6 shows a schematic diagram of a configuration flow of maximum power back-off (MPR) parameters in a possible implementation manner. For example, Table 1 shows the MPR corresponding to power level PC2, high-order modulation mode, and resource block (RB) configuration mode in the 3GPP protocol. There are multiple high-order modulation methods corresponding to the same power level. There are multiple RB configuration modes corresponding to the same power level. The RB configuration methods are shown in Table 1 as edge RB allocations, outer RB allocations, and inner RB allocations. Wherein, "edge RB allocations" refers to edge RB allocations, for example, the leftmost RB and the rightmost RB. "outer RB allocations" refers to all RB allocations. "Inner RB allocations" refers to internal RB allocations, for example, RBs adjacent to edge RBs, or, the middlemost half of RBs.

Assuming that the power level of the terminal device 100 is PC2, as shown in FIG. 6 , the terminal device 100 can use the maximum MPR corresponding to both the high-order modulation mode and the RB configuration mode shown in Table 1 as the preset MPR of the terminal device 100 parameters to configure. For example, the terminal device 100 writes the maximum MPR corresponding to both the high-order modulation mode and the RB configuration mode shown in Table 1 into the NV of the terminal device 100 through the operating system.

Table 1 MPR corresponding to PC2, high-order modulation mode, and RB configuration mode

The preconfigured target power and the preconfigured maximum power backoff (MPR) of the terminal device 100 may be written into the NV of the terminal device 100 before the terminal device 100 leaves the factory, so that the terminal device 100 transmits uplink data according to the terminal The preset target power corresponding to the current power level of the device 100, and the preset maximum power fallback (MPR) corresponding to the current power level of the terminal device 100, the current high-order modulation mode, and the current RB configuration mode Calculate and obtain the transmit power Pm corresponding to the current power level of the terminal device 100, the current high-order modulation mode, and the current RB configuration mode, and use the transmit power Pm to transmit the signal corresponding to the uplink data to transmit the uplink data .

The uplink transmission capability of the terminal device 100 is positively correlated with the transmit power Pm of the terminal device 100 . The transmit power Pm of the terminal device 100 is the difference between the maximum transmit power (maxpower) supported by the terminal device 100 and the MPR. In other words, in order to meet the linearity requirements of the power amplifier of the terminal device 100 and maintain the linearity of the power amplifier, the actual The transmit power Pm of is generally lower than the maximum transmit power (maxpower) that the terminal device 100 can support. The maximum transmission power (maxpower) that the terminal device 100 can support is the preset target power Ptar on the terminal device 100 .

In a possible implementation, the preset MPR parameters on the terminal device 100 are configured using predefined values applicable to the communication protocols of all terminal devices 100, regardless of the performance differences of the terminal devices 100, all terminal devices 100 preset The remaining power margin is the same. All terminal devices 100 include terminal devices 100 of different types and provided by different terminal device manufacturers. According to the experimental analysis, if the preset target power and the preset MPR parameters on the terminal device 100 are configured according to the configuration shown in Figure 5 and Figure 6, when the terminal device 100 performs uplink data transmission, the power amplifier during the transmission process There is a large margin in indicators such as linearity. In the transmission process, there is a large margin in indicators such as power amplifier linearity, which indicates that the power margin (such as the preset MPR) reserved by the terminal device 100 is too large, resource scheduling cannot be optimized during uplink data transmission, and spectrum utilization The transmission rate of the uplink data of the terminal device 100 is low, and the performance of the communication system and the transmission resources of the communication system are not fully utilized.

In view of this, the embodiment of the present application proposes a method for processing communication parameters, by adjusting the preset maximum power back-off (MPR) parameters of the terminal equipment to increase the transmission power of the terminal equipment, thereby solving the problem of uplink transmission of the terminal equipment. The problem of low data transfer rates.

The solutions provided by the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

Fig. 7 is the first flow chart of the communication parameter processing method provided by the embodiment of the present application, Fig. 8 is the second flow chart of the communication parameter processing method provided by the embodiment of the present application, and Fig. 9 is the DPD calibration equal compression curve provided by the embodiment of the present application schematic diagram. The execution subject of the embodiment shown in FIG. 7 and FIG. 8 may be the terminal device 100 in the embodiment shown in FIG. equipment. As shown in Figure 7, the method includes:

S101. Acquire first power information, second power information, and third power information corresponding to a power level of the terminal device 100. Wherein, the first power information is the maximum transient power Pmax allowed to be transmitted during calibration at the output port of the radio frequency test socket on the radio frequency link of the terminal device 100 . The second power information is the maximum saturation power Psat obtained during calibration at the output port of the radio frequency test socket on the radio frequency link of the terminal device 100 . The third power information is the maximum power Pprtcl allowed to be transmitted by the communication protocol at the output port of the radio frequency test socket on the radio frequency link of the terminal device 100 .

In the embodiment of the present application, the communication protocol is, for example, a third generation partnership project (3rd generation partnership project, 3GPP) protocol. Calibration may include digital pre-distortion (DPD) calibration.

Usually, the core of DPD calibration is to maintain the linearity of the power amplifier and obtain the equal compression characteristics of the signal to be transmitted (such as the signal corresponding to the uplink data). DPD calibration is fixed on the relationship between the input power of the power amplifier (PA), the output power of the PA, and the voltage of the PA. Exemplarily, Table 2 shows the relationship between the input power of the PA, the output power of the PA, and the voltage of the PA in the DPD calibration log.

Table 2 Relationship between PA input power/output power/voltage in DPD calibration log

As shown in Table 2 and Figure 9, under 4 different calibration voltages, 6 equal compression curves of different compression points (that is, the curves drawn by the four power points in the calibration power) are found. During DPD calibration, the saturated power is easily limited by the voltage Vcc of the PA, and the output power of the PA obtained under the maximum voltage Vcc is the saturated power Psat of the terminal device 100 . When the compression point requires 3db, the equal compression curves obtained from 4 different calibration voltages are shown in Figure 9. As shown in Table 2, when the voltage is limited by the maximum operating voltage of the PA (for example, the specification is 5 volts, and the measured value is 4935 millivolts), the calibrated maximum saturated power Psat is 28.7dbm. Currently, among the power classes PC2 and PC3, the power value Ptarpc corresponding to the power class PC2 is higher than the power value Ptarpc corresponding to the PC3, and the power value Ptarpc corresponding to the power class PC2 is usually 26dbm. As shown in Table 2, the calibrated maximum saturated power Psat of the terminal device 100 is 28.7dbm. If the transmit power Pm of the terminal device 100 meets the calibrated maximum saturated power Psat, the radio frequency index of the terminal device 100 meets the requirements of the communication protocol. Therefore, in the embodiment of the present application, the maximum power backoff parameter adjusted by the terminal device 100 according to the Psat obtained through DPD calibration and the determined target power also meet the requirements of the radio frequency index of the terminal device 100 .

Exemplarily, on the radio frequency link of the terminal device 100 , there is power loss between the output port of the power amplifier and the input port of the radio frequency test socket, that is, insertion loss (insertion loss, IL). Acquire sixth power information and insertion loss information of the terminal device 100 . Wherein, the sixth power information Ptrsnt is the instantaneous maximum output power Ptrsnt allowed to transmit by the power amplifier on the radio frequency link of the terminal device 100 when the terminal device 100 is calibrated. The insertion loss information is the power loss IL between the output port of the power amplifier on the radio frequency link of the terminal device 100 and the input port of the radio frequency test socket on the radio frequency link of the terminal device 100 .

Determine the difference between the sixth power information Ptrsnt and the insertion loss information IL as the first power information Pmax. As shown in FIG. 8 , calculate Pmax=Ptrsnt-IL, and obtain the maximum power Pmax allowed to be transmitted by the radio frequency test socket on the radio frequency link of the terminal device 100 . Generally, the value of the insertion loss IL of the terminal device 100 can be measured through experiments after the corresponding hardware is manufactured.

Exemplarily, as shown in FIG. 8 , the saturation power Psat at the maximum voltage obtained by DPD calibration of the terminal device 100 may be obtained, that is, the second power information Psat obtained by performing DPD calibration processing on the terminal device 100 may be obtained.

Exemplarily, seventh power information corresponding to the power level of the terminal device 100 is acquired. Wherein, the seventh power information is the estimated power Ptarpc at the output port of the radio frequency test socket on the radio frequency link of the terminal device 100 that meets the preset reliability requirements and communication protocol requirements.

The preset reliability requirement, for example, meets the linearity requirement of the power amplifier corresponding to the communication protocol. The power amplifier linearity characterizes the linearity of the power amplifier.

For each power level, the seventh power information Ptarpc corresponding to the power level, the preset power value range corresponding to the power level, and the preset upper threshold of power fluctuations during production corresponding to the power level can be used to determine the seventh power level corresponding to the power level. Three Power Information Pprtcl.

Exemplarily, the preset power value range corresponding to the power level is a power upper limit. According to the seventh power information Ptarpc corresponding to the power level, the power upper limit corresponding to the power level, and the preset upper threshold of power fluctuation during production corresponding to the power level, according to the formula:

Pprtcl=Ptarpc+power upper limit-upper threshold of power fluctuation during production

Determine third power information Pprtcl corresponding to the power level.

For example, in the 3GPP protocol, the preset power value ranges (such as power upper limit) corresponding to the power levels PC2 and PC3 respectively, and the corresponding preset upper thresholds of power fluctuations during production are shown in Table 3.

Table 3 The power upper limit corresponding to PC2 and PC3 respectively and the preset upper threshold of power fluctuation during production

If the power level of the terminal device 100 is PC2, according to the seventh power information Ptarpc corresponding to PC2 shown in Table 3, the power upper limit, and the preset upper threshold of power fluctuations during production corresponding to the power level, according to the formula:

Pprtcl=Ptarpc+power upper limit-upper threshold of power fluctuation during production

Determine the third power information Pprtcl=26+3-1.5=27.5 corresponding to the power class PC2.

Similarly, if the power class of the terminal device 100 is PC3, third power information Pprtcl=23+3−1.5=24.5 corresponding to the power class PC3 may be determined.

S102. According to the first power information, the second power information, and the third power information corresponding to the power level, adjust the maximum power backoff parameter in the preset parameter table of the terminal device 100 to obtain an adjusted parameter table. Wherein, the preset parameter table includes the maximum power back-off parameter corresponding to the power level, the high-order modulation mode and the resource block (RB) configuration mode.

In this embodiment of the present application, the maximum power backoff parameter in the preset parameter table of the terminal device 100 is, for example, the preset MPR parameter configured by the terminal device 100 according to the configuration process shown in FIG. 6 . The terminal device 100 may set back the maximum power (MPR) in the preset parameter table of the terminal device 100 according to the first power information Pmax, the second power information Psat, and the third power information Pprtcl corresponding to the power level of the terminal device 100. The parameters are adjusted to obtain the adjusted parameter table. The preset parameter table of the terminal device 100 includes preset MPR parameters corresponding to the power level, high-order modulation mode, and RB configuration mode.

The first power information Pmax and the third power information Pprtcl may correspond to communication protocol requirements, and the second power information Psat may correspond to reliability requirements of the power amplifier. According to the first power information Pmax, the second power information Psat, and the third power information Pprtcl corresponding to the power level, the maximum power fallback MPR parameter in the preset parameter table of the terminal device 100 is adjusted to obtain a communication protocol that meets the requirements of the communication protocol. And meet the maximum power fallback MPR required by the reliability of the power amplifier. Usually, when the terminal device 100 is calibrated, the transient maximum output power Ptrsnt allowed to be transmitted by the power amplifier on the radio frequency link of the terminal device 100 is greater than the maximum steady-state power Ppa allowed to be emitted at the output port of the power amplifier defined in the device manual, so , Pmax>Pmax1. In addition, Pprtcl>Ptarpc, Pmax1 will usually be smaller than Psat. Therefore, according to the first power information Pmax, the second power information Psat, and the third power information Pprtcl corresponding to the power level, the maximum power fallback MPR parameter in the preset parameter table of the terminal device 100 is adjusted to obtain The device 100 configures the preset maximum power backoff parameter according to the process shown in FIG. 6 , and the smaller maximum power backoff parameter to increase the transmission power of the terminal device, thereby solving the problem of low transmission rate during uplink transmission.

Exemplarily, for the same power level, when the minimum value of the first power information Pmax, the second power information Psat, and the third power information Pprtcl corresponding to the power level, such as min(Pmax, Psat, Pprtcl), is the power level When corresponding to the third power information Pprtcl, the maximum power fallback (MPR) parameter in the preset parameter table of the terminal device 100 may be adjusted according to the third power information Pprtcl corresponding to the power level to obtain the adjusted parameter table .

For the same power level, if the minimum value among the first power information, the second power information, and the third power information corresponding to the power level is the third power information corresponding to the power level, it represents the performance of the radio frequency test socket on the radio frequency link of the terminal device 100. The maximum saturated power Psat obtained during calibration at the output port is greater than the maximum power Pprtcl allowed to be transmitted by the communication protocol at the output port of the RF test socket, that is, the maximum saturated power obtained during calibration at the output port of the RF test socket There is a margin, and the maximum power fallback parameter in the parameter table preset by the terminal device 100 can be adjusted to obtain a smaller maximum power fallback parameter that meets the reliability of the power amplifier. In this way, the transmitting power of the terminal device 100 can be improved. Power, and then solve the problem of low transmission rate during uplink transmission.

In this embodiment of the present application, the maximum power backoff MPR parameter in the preset parameter table is also referred to as a preset maximum power backoff (MPR) parameter. The MPR parameter corresponds to the power level, high-order modulation mode, and RB configuration mode. The preset MPR parameters also correspond to the power level, high-order modulation mode, and RB configuration mode. For ease of understanding, the method for processing communication parameters provided in this embodiment of the present application may be illustrated below by taking the power level of the terminal device 100 as PC2 or PC3 as an example.

Exemplarily, for the same power level, when the minimum value of the first power information Pmax, the second power information Psat, and the third power information Pprtcl corresponding to the power level is the third power information Pprtcl corresponding to the power level, it can be According to the third power information Pprtcl corresponding to the power level, according to the manner shown in S1021-S1023, the maximum power back-off (MPR) parameter in the preset parameter table is adjusted to obtain the adjusted parameter table.

S1021. Obtain the peak-to-average ratio corresponding to the maximum power backoff parameter in the preset parameter table. Wherein, the peak-to-average ratio represents the power information of the power amplifier on the radio frequency link of the terminal device 100 when transmitting. Generally, the peak-to-average ratio is the area of the power of the power amplifier when it is transmitted under the modulation mode. The peak-to-average ratio is usually an empirical value.

S1022. According to the peak-to-average ratio corresponding to the preset maximum power back-off parameter, adjust the preset maximum power back-off parameter to obtain an adjustment parameter corresponding to the preset maximum power back-off parameter.

S1023. For the same power level, determine the adjusted maximum power backoff parameter according to the third power information corresponding to the power level and the adjustment parameter corresponding to the preset maximum power backoff parameter, so as to obtain an adjusted parameter table.

Exemplarily, the manner shown in S1021-S1023 will be described below by taking the power level of the terminal device 100 as PC3 as an example. For the same power class, for example for power class PC3.

Table 4 shows the peak-to-average ratio corresponding to the maximum power backoff parameter in the preset parameter table of the terminal device 100 whose power level is PC3.

Table 4 The maximum MPR, peak-to-average ratio, and compression state of the protocol corresponding to PC3, high-order modulation mode, and RB configuration mode

In the communication process between the terminal device 100 and the network device 200 as shown in Figure 3, there are differences in the signal peak-to-average ratios corresponding to the high-order modulation modes at the same power level, as shown in Table 4, and the signal peak-to-average ratio is too large to cause The power amplifier works in the non-linear region, resulting in signal distortion. Therefore, in order to maintain the linearity of the power amplifier, the terminal device 100 usually uses a DPD calibration method to correct the signal (such as the signal corresponding to the uplink data). The compression state represents the nonlinear state of the power amplifier. The greater the difference in the difference values of the compression state corresponding to each high-order modulation method, the greater the difference in the degree of nonlinear distortion of the power amplifier. In this way, the DPD calibration needs to be based on the modulation method. Different calibrations are performed multiple times, resulting in low DPD calibration benefits and affecting the uplink transmission rate. Since the characteristics of DPD calibration are equal compression, if the difference between the compression state difference values corresponding to each high-order modulation mode is reduced, such as making the corresponding compression states of each high-order modulation mode equal, the benefit of DPD calibration can be improved. Thus, the uplink transmission rate is increased. The compression state difference is usually the difference between the peak-to-average ratio and the MPR. Therefore, the MPR is adjusted based on the compression state difference, so that the corresponding compression states of each high-order modulation mode are equivalent, that is, the power amplifier that meets the linearity requirements of the power amplifier can be obtained. The adjusted MPR, and the uplink transmission is performed according to the adjusted MPR, which improves the DPD calibration benefit and further increases the uplink transmission rate. therefore,

Obtain the peak-to-average ratio corresponding to the MPR parameter in the preset parameter table of the terminal device 100 as shown in Table 4, that is, obtain the peak-to-average ratio corresponding to the preset MPR parameter of the terminal device 100 as shown in Table 4.

According to the peak-to-average ratio corresponding to the preset MPR parameters of the terminal device 100, adjust the preset MPR parameters of the terminal device 100 in the manner shown in S10221-S10223, and obtain the adjustment parameters corresponding to the preset MPR parameters:

S10221. Subtracting the peak-to-average ratio corresponding to the preset maximum power back-off parameter from the preset maximum power back-off parameter to obtain a compression state difference value corresponding to the preset maximum power back-off parameter.

S10222. For the same power level, determine the maximum value of the compression state difference values corresponding to the preset maximum power back-off parameters at the power level, and obtain the maximum difference value at the power level.

S10223. For the same power level, according to the maximum value of the difference under the power level, adjust the preset maximum power backoff parameter under the power level, and obtain the corresponding value of the preset maximum power backoff parameter under the power level. Tuning parameter MPRmod.

For example, the preset MPR parameter of the terminal device 100 is the protocol maximum MPR shown in Table 4.

According to the power backoff information MPRnv1 corresponding to the power level, high-order modulation mode, and resource block configuration mode, determine the adjusted maximum power backoff corresponding to the power level, high-order modulation mode, and resource block configuration mode. Return the parameter MPRnv to get the adjusted parameter table.

The preset value can be a value greater than or equal to 0.

For example, the default value can be 0. It can be judged whether the high-order modulation power of each high-order modulation mode meets the requirement of being smaller than the low-order modulation power in the following manner, so as to correct the MPRnv1 corresponding to the power level, high-order modulation mode and resource block configuration mode, and obtain The MPRnv corresponding to the power level, the high-order modulation method, and the resource block configuration method, and then obtain the adjusted parameter table: determine whether MPRnv1 is greater than 0, and if so, determine the power level, high-order modulation method and resource block The value of MPRnv1 corresponding to the three block configuration modes is the value of MPRnv corresponding to the power level, the high-order modulation mode, and the resource block configuration mode; if not, it indicates that the transmit power Pmod corresponding to the high-order modulation mode is greater than If the maximum power Pprtcl allowed to be transmitted by the communication protocol at the output port of the RF test socket on the RF link of the terminal equipment does not meet the requirements of the communication protocol, it is determined to correspond to the power level, the high-order modulation method, and the resource block configuration method. The value of MPRnv is 0.
