In this way, the terminal device 100 can play or record video in various encoding formats, for example: dynamic picture experts group (moving picture experts group, MPEG) 1, MPEG2, MPEG3, MPEG4, etc.

The NPU is a neural-network (NN) computing processor, and can rapidly process input information by referencing a biological neural network structure, for example, referencing a transmission mode between human brain neurons, and can also continuously perform self-learning. Applications such as intelligent awareness of the terminal device 100 may be implemented by the NPU, for example: image recognition, face recognition, speech recognition, text understanding, etc.

The external memory interface 120 may be used to connect an external memory card, such as a Micro SD card, to realize expansion of the memory capability of the terminal device 100. The external memory card communicates with the processor 110 through an external memory interface 120 to implement data storage functions. For example, files such as music, video, etc. are stored in an external memory card.

The internal memory 121 may be used to store computer-executable program code that includes instructions. The internal memory 121 may include a storage program area and a storage data area. The storage program area may store an application program (such as a sound playing function, an image playing function, etc.) required for at least one function of the operating system, etc. The storage data area may store data (such as audio data, phonebook, etc.) created during use of the terminal device 100, and the like. In addition, the internal memory 121 may include a high-speed random access memory, and may further include a nonvolatile memory such as at least one magnetic disk storage device, a flash memory device, a universal flash memory (universal flash storage, UFS), and the like. The processor 110 performs various functional applications of the terminal device 100 and data processing 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 to connect a SIM card.

The software system of the terminal device 100 may employ a layered architecture, an event driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. In the embodiment of the invention, taking an Android system with a layered architecture as an example, a software structure of the terminal device 100 is illustrated.

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

The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, an application layer, an application framework layer, an Zhuoyun row (Android run) and system libraries, and a kernel layer, respectively.

The application layer may include a series of application packages.

As shown in fig. 2, the application package may include applications for cameras, gallery, calendar, phone calls, maps, navigation, WLAN, bluetooth, music, video, short messages, etc.

The application framework layer provides an application programming interface (application programming interface, API) and programming framework for application programs of the application layer. The application framework layer includes a number of predefined functions.

As shown in FIG. 2, the application framework layer may include a window manager, a content provider, a view system, a telephony manager, a resource manager, a notification manager, and the like.

The window manager is used for managing window programs. The window manager can acquire the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

The content provider is used to store and retrieve data and make such data accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebooks, etc.

The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, a display interface including a text message notification icon may include a view displaying text and a view displaying a picture.

The telephony manager is used to provide the communication functions of the terminal device 100. Such as the management of call status (including on, hung-up, etc.).

The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like.

The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction. Such as notification manager is used to inform that the download is complete, message alerts, etc. The notification manager may also be a notification in the form of a chart or scroll bar text that appears on the system top status bar, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the terminal equipment vibrates, and an indicator light blinks.

Android run time includes a core library and virtual machines. Android run time is responsible for scheduling and management of the Android system.

The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

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

The system library may include a plurality of functional modules. For example: surface manager (surface manager), media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., openGL ES), 2D graphics engines (e.g., SGL), etc.

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

Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio and video encoding formats, such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc.

The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like.

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

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver.

The workflow of the terminal device 100 software and hardware is illustrated below in connection with capturing a photo scene.

When touch sensor 180K receives a touch operation, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into the original input event (including information such as touch coordinates, time stamp of touch operation, etc.). The original input event is stored at the kernel layer. The application framework layer acquires an original input event from the kernel layer, and identifies a control corresponding to the input event. Taking the touch operation as a touch click operation, taking a control corresponding to the click operation as an example of a control of a camera application icon, the camera application calls an interface of an application framework layer, starts the camera application, further starts a camera driver by calling a kernel layer, and captures a still image or video by the camera 193.

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

In order to maintain linearity of the power amplifier, the terminal device 100 requires a maximum power back-off (maximum power reduction, MPR) for uplink transmission. Fig. 3 is an uplink transmission scene diagram provided in the embodiment of the present application. Since power backoff is required in the high-order modulation scheme, as shown in fig. 3, when the terminal device 100 transmits uplink data to the network device 200 of the communication system in the high-order modulation scheme in the uplink transmission process, the terminal device 100 calculates the transmit power Pm according to the pre-configured target power and the pre-configured maximum power backoff (maximum power reduction, MPR) parameters on the terminal device 100, so as to transmit the uplink data corresponding signal by using the calculated transmit power Pm. The transmission of the uplink data corresponding signal is closely related to the radio frequency link of the terminal device. Fig. 4 is a schematic diagram of a radio frequency link of a terminal device according to 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 (PA), a filter, and a radio frequency test socket (RFswitch); the radio frequency integrated circuit is connected with the power amplifier, the power amplifier is connected with the filter, and the filter is connected with the radio frequency test seat.

In the embodiment of the present application, the preset target power is also referred to as a preset target power. The pre-configured maximum power back-off (MPR) parameter is also referred to as a pre-set maximum power back-off (MPR) parameter. In this embodiment of the present application, before shipment, the preset target power and the preset MPR parameter of the terminal device 100 may be written into a non-volatile memory (NV) of the terminal device 100 through an operating system of the terminal device 100 itself. Illustratively, after determining the preset target power and the preset MPR parameter of the terminal device 100, the working platform of the manufacturer of the terminal device 100 sends the determined preset target power and the determined preset MPR parameter to the terminal device 100, and writes the preset target power and the preset MPR parameter into the terminal device 100 through the operating system of the terminal device 100. Alternatively, after determining the preset target power and the preset MPR parameter of the terminal device 100, the terminal device 100 may write the preset target power and the preset MPR parameter into the terminal device 100 through the operating system of the terminal device 100.

In a possible implementation manner, the target power Ptar preconfigured on the terminal device 100 is configured according to the power value Ptarpc1 corresponding to the power class in the protocol, and the maximum power back-off MPR preconfigured on the terminal device 100 is configured according to the protocol maximum MPR. A protocol such as a third generation partnership project (3rd generation partnership project,3GPP) protocol.

For example, fig. 5 is a schematic diagram of a configuration flow of the target power Ptar in a possible implementation, and as shown in fig. 5, a staff member 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 smaller than Pmax1, if yes, the value of the preset target power Ptar is set to be the value of Ptarpc1, the preset target power Ptar is written into a nonvolatile memory (NV) of the terminal device 100 through an operating system of the terminal device 100, if not, the value of the preset target power Ptar is set to be the value of Pmax1, and the preset target power Ptar is written into the NV of the terminal device 100 through the operating system of the terminal device 100. Wherein pmax1= Ppa-IL. Pmax1 is the steady state maximum power allowed to be transmitted when not calibrated at the rf test socket output port on the rf link of the terminal device 100. Ppa is the maximum steady state power allowed to be delivered at the power amplifier output port defined in the device manual. IL is the power loss during transmission of the upstream data signal in the radio frequency link of the terminal device 100 after output from the power amplifier and before input to the radio frequency test pad. IL is also known as Insertion Loss (IL). Ptarpc1 is the power value corresponding to the power class defined by the protocol. For example, according to the 3GPP protocol, the power class PC2 (power class 2) corresponds to the power value ptarbc 1 of 26dbm, and the power class PC3 (power class 3) corresponds to the power value ptarbc 1 of 24.5dbm.

For example, when Ptarpc1 < Pmax1, the value of Ptarpc1 is written as the value of the preset target power Ptar to the NV of the terminal device 100. When Ptarpc is more than or equal to Pmax1, writing the value of Pmax1 as the value of the preset target power Ptar into NV of the terminal equipment. In a possible implementation, the target power ptar=min (Pmax 1, ptarpc 1) preset by the terminal device 100.

In a possible implementation, the pre-configured MPR parameters on the terminal device 100 are configured per protocol maximum MPR. For example, the MPR parameters preconfigured in the terminal device 100 are configured according to the maximum MPR corresponding to the three modes of the power class, the higher order modulation mode and the RB configuration mode in the 3GPP protocol.

Fig. 6 shows a schematic flow diagram of the configuration of the maximum power back-off (MPR) parameters in a possible implementation. For example, table 1 shows MPRs corresponding to the three power classes PC2, the higher order modulation scheme, and the Resource Block (RB) configuration scheme in the 3GPP protocol. There are multiple higher order modulation modes corresponding to the same power level. And a plurality of RB configuration modes are corresponding to the same power level. RB configurations are edge RB allocations, outer RB allocations, inner RB allocations shown in table 1. Where "edge RB allocations" refers to edge RB allocations, e.g., leftmost RBs and rightmost RBs. "outer RB allocations" refers to all RB allocations. "inner RB allocations" refers to an internal RB allocation, e.g., RBs adjacent to an edge RB, or the middle-most half of RBs.

Assuming that the power class of the terminal device 100 is PC2, as shown in fig. 6, the terminal device 100 may be configured using the maximum MPR corresponding to both the higher order modulation scheme and the RB configuration scheme shown in table 1 as preset MPR parameters of the terminal device 100. For example, the terminal device 100 writes the maximum MPR corresponding to both the higher order modulation scheme and the RB configuration scheme shown in table 1 to the NV of the terminal device 100 via the operating system.

Table 1 MPR corresponding to PC2, higher order modulation scheme, RB configuration scheme

The pre-configured target power and the pre-configured maximum power back-off (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 when the terminal device 100 transmits uplink data, the terminal device 100 calculates according to the preset target power corresponding to the current power level of the terminal device 100 and the preset maximum power back-off (MPR) corresponding to the current power level, the current high-order modulation mode and the current RB configuration mode of the terminal device 100, to obtain the transmission power Pm corresponding to the current power level, the current high-order modulation mode and the current RB configuration mode of the terminal device 100, and transmit the uplink data corresponding signal by adopting the transmission power Pm to transmit uplink data.

The uplink transmission capability of the terminal device 100 is positively correlated with the transmission power Pm of the terminal device 100. The transmission power Pm of the terminal device 100 is the difference between the maximum transmission power (maxpower) supportable by the terminal device 100 and MPR, in other words, in order to meet the linearity requirement of the power amplifier of the terminal device 100, the power amplification degree is maintained, and the actual transmission power Pm of the terminal device 100 is generally lower than the maximum transmission power (maxpower) supportable by the terminal device 100. The maximum transmission power (maxpower) that the terminal device 100 can support is, for example, a target power Ptar preset on the terminal device 100.

In a possible implementation, the MPR parameters preset on the terminal devices 100 are configured with predefined values applicable to the communication protocol of all terminal devices 100, the power headroom reserved for all terminal devices 100 being the same, regardless of differences in the performance of the terminal devices 100. All terminal devices 100 include terminal devices 100 of different types, provided by different terminal device manufacturers. According to the experimental analysis, if the preset target power and the preset MPR parameter on the terminal device 100 are configured according to the configuration modes shown in fig. 5 and fig. 6, there is a large margin for indexes such as the power amplification degree in the transmission process when the terminal device 100 performs uplink data transmission. The indexes such as the power amplification degree and the like in the transmission process have larger allowance, which indicates that the reserved power allowance (such as preset MPR) of the terminal equipment 100 is larger, the resource scheduling cannot reach the optimum in the uplink data transmission process, the spectrum utilization rate is low, the performance of the communication system and the transmission resources of the communication system are not fully utilized, and the transmission rate of the uplink data of the terminal equipment 100 is low.

In view of this, the embodiments of the present application provide a method for processing communication parameters, which adjusts preset maximum power back-off (MPR) parameters of a terminal device to improve the transmission power of the terminal device, so as to solve the problem of low uplink data transmission rate of the terminal device.

The following describes the scheme provided in the embodiments of the present application in detail with reference to the accompanying drawings.

Fig. 7 is a flowchart of a processing method of a communication parameter provided in an embodiment of the present application, fig. 8 is a flowchart of a processing method of a communication parameter provided in an embodiment of the present application, and fig. 9 is a schematic diagram of a compression curve such as DPD calibration provided in an embodiment of the present application. The execution subject of the embodiment shown in fig. 7 and 8 may be the terminal device 100 in the embodiment shown in fig. 3, or may be a working platform of a manufacturer of the terminal device 100, or may be other electronic devices that may communicate with the terminal device 100. As shown in fig. 7, the method includes:

s101, acquiring first power information, second power information, and third power information corresponding to a power class of the terminal device 100. 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 psa 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 that the communication protocol is allowed to transmit at the output port of the radio frequency test socket on the radio frequency link of the terminal device 100.

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

Typically, the core of DPD calibration is to maintain the linearity of the power amplifier, resulting in a compressed characteristic of the signal to be transmitted (e.g., the signal corresponding to the uplink data). DPD calibration is fixed in relation to the input power of the Power Amplifier (PA), the output power of the PA, the voltage of the PA. Illustratively, 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 DPD calibration log relationship between PA input power/output power/voltage

As shown in table 2 and fig. 9, the compression curve for 6 different compression points (i.e., the curve depicted by four power points in the calibration power) was found at 4 different calibration voltages. The saturated power at DPD calibration is easily limited by the voltage Vcc of the PA, and the output power of the PA obtained at the maximum voltage Vcc is the saturated power psa of the terminal device 100. The compression curve obtained from 4 different calibration voltages at the compression point claim 3db is shown in figure 9. As shown in table 2, when the voltage is limited to the PA maximum operating voltage (e.g., 5 volts gauge, 4935 millivolts measured), a calibrated maximum saturation power psa of 28.7dbm is obtained. Currently, among the power classes PC2 and PC3, the power value ptarbc corresponding to the power class PC2 is higher than the power value ptarbc corresponding to PC3, and the power value ptarbc corresponding to the power class PC2 is generally 26dbm. As shown in table 2, the calibration maximum saturation power psa of the terminal device 100 is 28.7dbm, and if the transmission power Pm of the terminal device 100 meets the calibration maximum saturation power psa, the radio frequency index of the terminal device 100 meets the communication protocol requirement. Therefore, in the embodiment of the present application, the terminal device 100 also meets the radio frequency index requirement of the terminal device 100 according to the Psat obtained by DPD calibration, the adjusted maximum power back-off parameter and the determined target power.

Illustratively, on the radio frequency link of the terminal device 100, there is a power loss, i.e., insertion Loss (IL), between the output port of the power amplifier and the input port of the radio frequency test socket. Sixth power information and insertion loss information of the terminal device 100 are acquired. When the sixth power information ptrcnt is calibrated by the terminal device 100, the power amplifier on the radio frequency link of the terminal device 100 allows the transmitted transient maximum output power ptrcnt. The insertion loss information is the power loss IL from the output port of the power amplifier on the radio frequency link of the terminal device 100 to the input port of the radio frequency test socket on the radio frequency link of the terminal device 100.

The difference between the sixth power information ptrcnt and the insertion loss information IL is determined as the first power information Pmax. As shown in fig. 8, pmax=ptrcnt-IL is calculated to 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. In general, the value of insertion loss IL of terminal device 100 may be experimentally measured after the corresponding hardware fabrication is completed.

Illustratively, as shown in fig. 8, the maximum voltage saturated power Psat obtained by DPD calibration of the terminal device 100 may be acquired, and the second power information Psat obtained by DPD calibration processing of the terminal device 100 may be acquired.

Illustratively, seventh power information corresponding to the power level of the terminal device 100 is acquired. The seventh power information is that the power ptarcc meeting the preset reliability requirement and the communication protocol requirement is obtained by budgeting at the output port of the radio frequency test seat on the radio frequency link of the terminal device 100.

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

For each power class, the third power information Pprtcl corresponding to the power class may be determined according to the seventh power information ptarcc corresponding to the power class, the preset power value range corresponding to the power class, and the preset upper threshold of the power fluctuation at the time of production corresponding to the power class.

The preset power range, such as the upper power limit, corresponding to the power level is exemplary. The formula may be calculated according to the seventh power information ptarcc corresponding to the power level, the upper power limit corresponding to the power level, and the preset upper threshold of the power fluctuation during production corresponding to the power level:

pprtcl=ptarpc+upper power limit-upper threshold for power fluctuation at production

And determining third power information Pprtcl corresponding to the power level.

For example, in the 3GPP protocol, the preset power range (such as the upper power limit) and the corresponding preset upper threshold of the power fluctuation at the time of production are shown in table 3, where the power levels PC2 and PC3 correspond to each other.

Table 3 upper power limits and preset upper thresholds for power fluctuation at the time of production for PC2 and PC3, respectively

If the power level of the terminal device 100 is PC2, the following formula may be applied according to the seventh power information Ptarpc, the upper power limit, and the preset upper threshold of the power fluctuation at the time of production corresponding to the power level shown in table 3 and corresponding to PC 2:

Third power information pprtcl=26+3-1.5=27.5 corresponding to the power level PC2 is determined.

Similarly, if the power level of the terminal device 100 is PC3, the third power information pprtcl=23+3-1.5=24.5 corresponding to the power level 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, the maximum power back-off parameter in the preset parameter table of the terminal device 100 is adjusted, and the adjusted parameter table is obtained. The preset parameter table includes a maximum power back-off parameter corresponding to the power level, the high-order modulation mode and the Resource Block (RB) configuration mode.

In the embodiment of the present application, the maximum power back-off parameter in the preset parameter table of the terminal device 100, for example, the preset MPR parameter configured by the terminal device 100 according to the configuration flow shown in fig. 6. The terminal device 100 may adjust a maximum power back-off (MPR) parameter in a preset parameter table of the terminal device 100 according to the first power information Pmax, the second power information Psat, and third power information Pprtcl corresponding to a power class of the terminal device 100, to obtain an adjusted parameter table. The preset parameter table of the terminal device 100 includes preset MPR parameters corresponding to the power class, the high-order modulation mode and the RB configuration mode.

The first power information Pmax and the third power information Pprtcl may correspond to a communication protocol requirement, and the second power information psa may correspond to a reliability requirement 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 back-off MPR parameter in the preset parameter table of the terminal device 100 is adjusted, so that the maximum power back-off MPR meeting the communication protocol requirement and meeting the reliability requirement of the power amplifier can be obtained. Typically, when the terminal device 100 is calibrated, the instantaneous maximum output power ptrcnt that the power amplifier on the radio frequency link of the terminal device 100 is allowed to transmit is greater than the maximum steady state power Ppa allowed to issue at the power amplifier output port defined in the device manual, and therefore Pmax > Pmax1. Furthermore, pprtcl > Ptarpc, pmax1 will typically be less 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 back-off MPR parameter in the preset parameter table of the terminal device 100 is adjusted, so that a smaller maximum power back-off parameter can be obtained than the preset maximum power back-off parameter configured by the terminal device 100 according to the flow shown in fig. 6, so as to improve the transmission power of the terminal device, and further solve the problem of low transmission rate during uplink transmission.

For example, for the same power level, when the minimum value, such as min (Pmax, psat, pprtcl), 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, the maximum power back-off (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, so as to obtain the adjusted parameter table.

For the same power class, if the minimum value in the first power information, the second power information and the third power information corresponding to the power class is the third power information corresponding to the power class, the maximum saturated power Psat obtained when the output port of the radio frequency test seat on the radio frequency link of the terminal equipment 100 is calibrated is larger than the maximum power Pprtcl allowed to be transmitted by the communication protocol at the output port of the radio frequency test seat, that is, the maximum saturated power obtained when the output port of the radio frequency test seat is calibrated is characterized by having a margin, the maximum power back-off parameter in the parameter table preset by the terminal equipment 100 can be adjusted, and the smaller maximum power back-off parameter conforming to the reliability of the power amplifier is obtained, so that the transmitting power of the terminal equipment 100 can be improved, and the problem of low transmission rate in uplink transmission is solved.

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

For example, 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, the maximum power back-off (MPR) parameter in the preset parameter table may be adjusted according to the third power information Pprtcl corresponding to the power level in the manner shown in S1021-S1023, so as to obtain the adjusted parameter table.

S1021, obtaining a peak-to-average ratio corresponding to the maximum power back-off parameter in a preset parameter table. Wherein the peak-to-average ratio characterizes the power information of the power amplifier at transmission on the radio frequency link of the terminal device 100. In general, the peak-to-average ratio is the area of the power in the modulation mode when the power amplifier is transmitting. The peak-to-average ratio is typically an empirical value.

And S1022, adjusting the preset maximum power back-off parameter according to the peak-to-average ratio corresponding to the preset maximum power back-off parameter to obtain an adjustment parameter corresponding to the preset maximum power back-off parameter.

S1023, aiming at the same power level, determining the adjusted maximum power back-off parameter according to third power information corresponding to the power level and an adjustment parameter corresponding to a preset maximum power back-off parameter so as to obtain an adjusted parameter table.

Illustratively, the manner shown in S1021-S1023 will be described below with reference to the power class PC3 of the terminal device 100. For the same power class, for example for power class PC3.

The peak average ratio corresponding to the maximum power back-off parameter in the preset parameter table of the terminal device 100 with the power class PC3 is shown in table 4.

Table 4 protocol maximum MPR, peak-to-average ratio, compression state for PC3, higher order modulation scheme, RB configuration scheme

In the process of communication between the terminal device 100 and the network device 200 shown in fig. 3, peak-to-average ratios of signals corresponding to each higher-order modulation mode at the same power level are different, as shown in table 4, and an excessive peak-to-average ratio of the signals causes the power amplifier to operate in a nonlinear region, thereby causing signal distortion. Therefore, in order to maintain the power amplification degree, the terminal device 100 generally corrects the signal (such as the uplink data corresponding signal) by using a DPD calibration method. The larger the difference of the compression state difference values corresponding to the high-order modulation modes is, the larger the difference of the nonlinear distortion degrees of the power amplifier is represented, so that the DPD calibration needs to be performed for multiple times according to the different modulation modes, the DPD calibration benefit is low, and the uplink transmission rate is influenced. Because the characteristics of DPD calibration are compressed, if the difference between the compression state difference values corresponding to each high-order modulation mode is reduced, if the compression states corresponding to each high-order modulation mode are equivalent, the DPD calibration benefit can be improved, and the uplink transmission rate can be further improved. The compression state difference value is usually the difference value between the peak-to-average ratio and the MPR, so that the MPR is adjusted based on the compression state difference value, so that the compression states corresponding to the high-order modulation modes are equivalent, the adjusted MPR meeting the requirement of the power amplification degree can be obtained, the uplink transmission is performed according to the adjusted MPR, the DPD calibration benefit is improved, and the uplink transmission rate is further improved. Thus, the first and second substrates are bonded together,

The peak-to-average ratio corresponding to the MPR parameter in the preset parameter table of the terminal device 100 shown in table 4 is obtained, that is, the peak-to-average ratio corresponding to the preset MPR parameter of the terminal device 100 shown in table 4 is obtained.

According to the peak-to-average ratio corresponding to the preset MPR parameter of the terminal device 100, the preset MPR parameter of the terminal device 100 is adjusted in the manner shown in S10221-S10223 to obtain an adjustment parameter corresponding to the preset MPR parameter:

s10221, subtracting the preset maximum power back-off parameter from the peak-to-average ratio corresponding to the preset maximum power back-off parameter to obtain a compression state difference value corresponding to the preset maximum power back-off parameter.

S10222, determining the maximum value of compression state difference values corresponding to each preset maximum power back-off parameter under the same power level to obtain the difference maximum value under the power level.

S10223, aiming at the same power level, according to the difference maximum value under the power level, adjusting the preset maximum power back-off parameter under the power level to obtain an adjustment parameter MPRmod corresponding to the preset maximum power back-off parameter under the power level.

For example, the preset MPR parameters of the terminal device 100 are the protocol maximum MPR shown in table 4. The compression state difference value corresponding to the preset MPR parameter of the terminal device 100 is the pre-adjustment compression state difference value shown in table 4.

The peak-to-average ratio shown in table 4 is subtracted from the maximum MPR of the protocol shown in table 4 to obtain the compression state difference values (i.e., the pre-adjustment compression state difference values shown in table 4) corresponding to the PC3, the higher order modulation scheme, and the RB configuration scheme. The compression state difference value corresponding to the protocol maximum MPR shown in table 4 is shown as the pre-adjustment compression state difference value in table 4.

For the power level PC3 of the terminal device 100, the maximum value of the pre-adjustment compression state difference values corresponding to the maximum MPR of each protocol under PC3 as shown in table 4 is determined, and the difference maximum value under PC3 (5.36 of the pre-adjustment compression state difference values as shown in table 4) is obtained.

For the power class PC3 of the terminal device 100, the adjustment parameter MPRmod corresponding to the preset maximum power back-off parameter at the power class PC3 is the adjusted MPR shown in table 4. The protocol maximum MPR shown in table 4 was adjusted according to the difference maximum value 5.36 under PC3 shown in table 4, resulting in an adjusted MPR as shown in table 4.

For example, the protocol maximum MPR to be adjusted may be determined according to an absolute value of a difference between the pre-adjustment compression state difference value and the difference maximum value being greater than a first adjustment threshold. The maximum MPR of the protocol to be adjusted can be adjusted with an adjustment amplitude of 0.5 to obtain an adjusted MPR, and the absolute value of the difference between the adjusted compression state difference value and the difference maximum value corresponding to the adjusted MPR is smaller than or equal to a second adjustment threshold. The first adjustment threshold is, for example, 0.53. A second adjustment threshold, such as 0.55.

For example, according to the absolute value of the difference between the compression state difference value and the difference maximum value before adjustment being greater than the first adjustment threshold value 0.53, it is determined that the protocol maximum MPR to be adjusted under PC3 shown in table 4 is respectively: DFT-s-OFDM QPSK, DFT-s-OFDM 16 QAM, DFT-s-OFDM 64 QAM, DFT-s-OFDM 256 QAM, CP-OFDM 64 QAM and CP-OFDM 256 QAM respectively correspond to the maximum MPR of the protocol. The maximum MPR of the protocol to be adjusted in table 4 is adjusted with an adjustment amplitude of 0.5, respectively, to obtain an adjusted MPR:0.5, 1, 1.5, 3, 3.5, and the absolute value of the difference between the adjusted compression state difference value corresponding to the obtained adjusted MPR (adjusted compression state difference value: 5.23, 5.43, 5.5, 5.05, 5.33, 4.81, as shown in table 4) and the difference maximum value (5.36) is 0.55 or less.

According to the peak-to-average ratio corresponding to the preset MPR parameter of the terminal device 100, the maximum MPR (the preset MPR parameter of the terminal device 100 under PC 3) of the protocol shown in table 4 is adjusted in the manner shown in S10221-S10223, so as to obtain the adjusted MPR shown in table 4, where the adjusted MPR shown in table 4 is the adjustment parameter MPRmod corresponding to the preset MPR parameter of the terminal device 100 under the power level PC 3.

Further, when the minimum value, such as min (Pmax, psa), in the first power information Pmax and the second power information Psat is the fourth power information Pmpr, for the same power level (such as PC 3), according to the third power information Pprtcl corresponding to the power level, the fourth power information Pmpr, and the adjustment parameter MPRmod corresponding to the preset MPR parameter, the adjusted maximum power back-off parameter is determined in the manner shown in S10231-S10233, so as to obtain the adjusted parameter table. The fourth power information Pmpr characterizes the maximum power that can be called in each high-order modulation mode.

S10231, determining fourth power information Pmpr, and adjusting parameters MPRmod corresponding to preset maximum power back-off parameters corresponding to the power level, the high-order modulation mode and the RB configuration mode, wherein the difference value between the two parameters is fifth power information Pmod corresponding to the power level, the high-order modulation mode and the resource block RB configuration mode. The fifth power information is a target power (or maximum power) at an output port of the radio frequency test socket on the radio frequency link of the terminal device 100. For example, the formula:

Pmod=Pmpr-MPRmod

and calculating to obtain fifth power information Pmod corresponding to the power level, the high-order modulation mode and the RB configuration mode.

S10232, determining third power information Pprtcl corresponding to the power level, fifth power information Pmod corresponding to the power level, the high-order modulation mode and the resource block configuration mode according to the same power level, wherein the difference value between the third power information Pprtcl and the fifth power information Pmod is power back-off information MPRnv1 corresponding to the power level, the high-order modulation mode and the resource block configuration mode. For example, the formula:

MPRnv1=Pprtcl-Pmod

and calculating to obtain power back-off information MPRnv1 corresponding to the power level, the high-order modulation mode and the resource block configuration mode.

S10233, determining the adjusted maximum power back-off parameter MPRnv corresponding to the power level, the high-order modulation mode and the resource block configuration mode according to the power back-off information MPRnv1 corresponding to the power level, the high-order modulation mode and the resource block configuration mode so as to obtain an adjusted parameter table.

Illustratively, the higher order modulated power is less than or equal to the lower order modulated power, as required by the communication protocol. The higher order modulated power may be equal to the target power Pmod at the output port of the radio frequency test pad on the radio frequency link of the terminal device 100. The low-order modulated power may be equal to the maximum power Pprtcl that the communication protocol is allowed to transmit at the output port of the radio frequency test socket on the radio frequency link of the terminal device 100. Therefore, the terminal device 100 may correct the MPRnv1 based on the determination result of whether the high-order modulation power of the high-order modulation mode is less than or equal to the low-order modulation power, to obtain the adjusted maximum power back-off parameter MPRnv, and further obtain the adjusted parameter table.

For example, the adjusted maximum power back-off parameter MPRnv corresponding to the power level, the higher order modulation scheme, and the resource block configuration scheme may be determined as follows: when the power back-off information MPRnv1 corresponding to the power level, the high-order modulation mode and the resource block configuration mode is larger than or equal to a preset value, determining that the MPRnv1 is the MPRnv corresponding to the power level, the high-order modulation mode and the resource block configuration mode; when the power back-off information MPRnv1 corresponding to the power level, the high-order modulation mode and the resource block configuration mode is smaller than the preset value, determining the preset value as MPRnv corresponding to the power level, the high-order modulation mode and the resource block configuration mode. The preset value may be a value of 0 or more.

For example, the preset value may be 0. The method can determine whether the higher order modulation power of each higher order modulation mode meets the requirement of being smaller than the lower order modulation power, so as to correct the MPRnv1 corresponding to the power level, the higher order modulation mode and the resource block configuration mode to obtain the MPRnv corresponding to the power level, the higher order modulation mode and the resource block configuration mode, and further obtain the adjusted parameter table: determining whether MPRnv1 is larger than 0, if so, determining the values of MPRnv1 corresponding to the power level, the high-order modulation mode and the resource block configuration mode as the values of MPRnv corresponding to the power level, the high-order modulation mode and the resource block configuration mode; if the transmission power Pmod corresponding to the high-order modulation mode is larger than the maximum power Pprtcl allowed to be transmitted by the communication protocol at the output port of the radio frequency test seat on the radio frequency link of the terminal equipment, and the communication protocol requirement is not met, determining that the MPRnv corresponding to the power level, the high-order modulation mode and the resource block configuration mode is 0.

In this way, the obtained adjusted maximum power back-off parameters corresponding to the power level, the high-order modulation mode and the resource block configuration mode are in accordance with the communication protocol requirement, the power amplification reliability requirement of the terminal equipment and the value is minimum.

Further, after determining the adjusted maximum power back-off parameters corresponding to the power level, the high-order modulation mode and the resource block configuration mode, the maximum power back-off parameters in the preset parameter table of the terminal device 100 may be correspondingly modified to the adjusted maximum power back-off parameters based on the power level, the high-order modulation mode and the resource block configuration mode, so as to obtain an adjusted parameter table, so as to execute step S103 finally.

Similarly, taking the power class of the terminal device 100 as PC3 as an example, the adjusted parameter table can be obtained by modifying the protocol maximum MPR mapping in table 4 to the adjusted maximum power back-off parameter based on the PC3, the higher order modulation scheme and the resource block configuration scheme.

Optionally, 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, for example, min (Pmax, psat, pprtcl), is not the third power information Pprtcl corresponding to the power level, the peak-to-average ratio corresponding to the maximum power backoff parameter in the preset parameter table may be obtained. According to the acquired peak-to-average ratio, the preset maximum power back-off parameter is adjusted according to the mode shown in S1024-S1026 to obtain an adjusted maximum power back-off parameter, so as to obtain an adjusted parameter table:

S1024, subtracting the maximum power back-off parameter from the peak-to-average ratio corresponding to the preset maximum power back-off parameter to obtain a compression state difference value corresponding to the preset maximum power back-off parameter. The implementation principle of step S1024 is similar to that of step S10221, and will not be described here again.

S1025, determining the maximum value of compression state difference values corresponding to each preset maximum power back-off parameter under the power level according to the same power level, and obtaining the difference maximum value under the power level. The implementation principle of step S1025 is similar to that of step S10222, and will not be described here.

S1026, aiming at the same power level, according to the difference maximum value under the power level, adjusting the preset maximum power back-off parameter under the power level to obtain an adjustment parameter MPRmod corresponding to the preset maximum power back-off parameter under the power level; and determining the corresponding adjustment parameters of the preset maximum power back-off parameters as the adjusted maximum power back-off parameters corresponding to the corresponding power class, the high-order modulation mode and the RB configuration mode. Therefore, the difference between compression state difference values corresponding to the high-order modulation modes can be reduced, so that the compression states corresponding to the high-order modulation modes are equivalent under the same power level, DPD calibration benefits are improved, and further the uplink transmission rate is improved. For the same power level, the preset maximum power back-off parameter under the power level may be adjusted according to the difference maximum value under the power level in a similar manner in step S10223, to obtain an adjustment parameter MPRmod corresponding to the preset maximum power back-off parameter under the power level.

Further, after determining the adjusted maximum power back-off parameters corresponding to the power level, the high-order modulation mode and the resource block configuration mode, the terminal device 100 correspondingly modifies the maximum power back-off parameters in the parameter table preset on the terminal device 100 to the adjusted maximum power back-off parameters based on the power level, the high-order modulation mode and the resource block configuration mode, so as to obtain an adjusted parameter table, so as to facilitate execution of step S103.

S103, writing the adjusted parameter table into the terminal equipment 100.

In the embodiment of the present application, if the preset parameter table of the terminal device 100 is not written into the NV of the terminal device 100, the adjusted parameter table obtained in step S102 may be written into the NV of the terminal device 100 by the operating system of the terminal device 100. If the preset parameter table of the terminal device 100 is already written in the NV of the terminal device 100 in advance, the preset parameter table in the NV of the terminal device 100 is cleared, and the adjusted parameter table obtained in step S102 is written in the NV of the terminal device 100, so that the terminal device 100 calculates the transmission power of the uplink data corresponding signal according to the written target power and the written MPR parameter in the NV on the terminal device 100.

Optionally, the adjusted maximum power backoff parameter obtained in step S102 and corresponding to the three power level, the higher order modulation scheme and the resource block configuration scheme may be written into the NV of the terminal device 100 in a table form, or may be written into the NV of the terminal device 100 in a form of a set of parameters other than the table.

Optionally, after the first power information Pmax, the second power information Psat, and the third power information Pprtcl corresponding to the power class of the terminal device 100 are acquired in step S101, the target power Ptarnv corresponding to the power class may be determined according to the first power information Pmax, the second power information Psat, and the third power information Pprtcl corresponding to the power class. The target power Ptarnv corresponding to the power level is written into the NV of the terminal device 100, so that the terminal device 100 determines the transmission power of the uplink data corresponding signal according to the written target power Ptarnv and the written MPR parameter. The target power Ptarnv is the power at the output port of the radio frequency test socket on the radio frequency link of the terminal device 100, which meets the preset reliability requirement and the communication protocol requirement. The MPR parameters written by the terminal device 100 are the adjusted maximum power back-off parameters corresponding to the power level, the higher order modulation scheme, and the resource block allocation scheme written in step S103.

The first power information Pmax and the third power information Pprtcl may correspond to requirements of a communication protocol, and the second power information psa may correspond to reliability of a power amplifier. The terminal device 100 determines the target power Ptarnv corresponding to the power class according to the first power information Pmax, the second power information Psat, and the third power information Pprtcl corresponding to the power class, and may obtain the target power Ptarnv corresponding to the power class that meets the communication protocol requirement and meets the reliability requirement of the power amplifier. Typically, when the terminal device 100 is calibrated, the instantaneous maximum output power ptrcnt that the power amplifier on the radio frequency link of the terminal device 100 is allowed to transmit is greater than the maximum steady state power Ppa allowed to issue at the power amplifier output port defined in the device manual, and therefore Pmax > Pmax1. Furthermore, pprtcl > Ptarpc, pmax1 will typically be less than Psat. Therefore, the target power Ptarnv corresponding to the power level is determined according to the first power information Pmax, the second power information Psat, and the third power information Pprtcl corresponding to the power level, so that a target power Ptarnv greater than the preset target power Ptar configured by the terminal device 100 according to the flow shown in fig. 5 can be obtained, so as to improve the transmission power of the terminal device, and further solve the problem of low transmission rate during uplink transmission.

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 of the terminal device 100 is not the third power information Pprtcl corresponding to the power level, the minimum value between the first power information Pmax and the second power information Psat is determined as the target power Ptarnv corresponding to the power level of the terminal device 100.

As shown in fig. 8, when min (Pmax, psat, pprtcl) +.pprtcl, ptarnv=min (Pmax, psat) is determined, and the determined Ptarnv is written in NV of the terminal apparatus 100.

For example, 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, the third power information Pprtcl corresponding to the power level is determined to be the target power Ptarnv corresponding to the power level.

As shown in fig. 8, when min (Pmax, psat, pprtcl) =pprtcl, ptarnv=pprtcl is determined, and the determined Ptarnv is written in NV of the terminal apparatus 100. Further, the terminal device 100 may determine MPRnv corresponding to the power level, the high-order modulation mode, and the RB configuration mode according to steps S102 to S103, and write the determined MPRnv corresponding to the power level, the high-order modulation mode, and the RB configuration mode into NV of the terminal device 100.

Further, the terminal device 100 may determine the transmission power Pm corresponding to the current power level, the current high-order modulation mode, and the current Resource Block (RB) configuration mode according to the target power Ptarnv corresponding to the current power level and the MPRnv corresponding to the current power level, the current high-order modulation mode, and the current RB configuration mode. The terminal device 100 transmits uplink data using the transmission power Pm.

When the target power Ptarnv is regarded as the maximum transmission power (maxpower) supportable by the terminal device 100, the transmission power Pm of the terminal device can be increased.

Alternatively, if the modulation mode of the terminal device 100 is a low-order modulation mode, the terminal device 100 may determine the transmission power corresponding to the current power level according to the target power Ptarnv corresponding to the current power level, and transmit the uplink data using the determined transmission power.

The following describes a processing method of communication parameters provided in the embodiment of the present application by way of an example.

Assuming that the operating band of the terminal device 100 is N78, the power class is PC2, ptrcnt=31dbm, and il=1.5 db for the components used on the radio frequency link of the terminal device 100. The terminal device 100 DPD calibration yields psat=28.7dbm. Pprtcl=27.5 dbm is calculated after querying the communication protocol. Pmax=ptrcnt-il=29.5 dbm. Min (Pmax, psat, pprtcl) =27.5 dbm of the terminal device 100. The terminal device 100 determines ptarnv=27.5 dbm, and the terminal device 100 writes the determined Ptarnv to the NV of the terminal device 100 through the operating system of the terminal device 100, for example, the terminal device 100 writes the determined Ptarnv to the Ptarnv storage area in the NV of the terminal device 100. The Ptarnv determined by the terminal device 100 using the processing method of the communication parameters provided in the embodiment of the present application is improved by 1.5dbm compared with the preset target power ptar=26 dbm determined in the possible implementation shown in fig. 5. Further, in the higher order modulation CP-OFDM 256QAM, when the mprmod=3.5 determined by the processing method for the communication parameter provided in the embodiment of the present application is adopted, pmod=28.7-3.5=25.2 dbm, the terminal device 100 may determine mprnv=27.5-25.2=2.3 db, and write mprnv=2.3 db into the NV of the terminal device 100, for example, the terminal device 100 writes mprnv=2.3 db into the MPR storage area in the NV of the terminal device 100. The value of MPRnv determined by the terminal device 100 using the processing method of the communication parameter provided in the embodiment of the present application is reduced by 4.2db compared with the preset MPR value determined in the possible implementation shown in fig. 6 (for example, the maximum MPR of the protocol corresponding to CP-OFDM 256QAM is 6.5 db). Accordingly, compared to the preset MPR determined in the possible implementation manner shown in fig. 6, the terminal device 100 adopts the MPRnv determined by the processing method of the communication parameter provided in the embodiment of the present application, so that the transmission power of the terminal device 100 is improved by 4.2db.

The improvement of the transmitting power of the terminal equipment can also realize the improvement of the air interface (OTA) performance of the terminal equipment. In addition, according to the processing method of the communication parameters provided by the embodiment of the application, the output port of the radio frequency test seat on the radio frequency link of the terminal equipment is determined according to the maximum transient power allowed to be transmitted when the output port of the radio frequency test seat on the radio frequency link of the terminal equipment is calibrated, the maximum saturated power obtained when the output port of the radio frequency test seat is calibrated, and the maximum power allowed to be transmitted by the communication protocol at the output port of the radio frequency test seat corresponding to the power level of the terminal equipment, the target power Ptarnv meeting the preset reliability requirement and the communication protocol requirement is met, and the determined target power Ptarnv is higher than the preset target power of the terminal equipment, so that the transmitting power of the terminal equipment is further improved. According to the processing method of the communication parameters, the purpose of dynamically adjusting the target power of each terminal device and the MPR of the high-order modulation mode according to the saturated power calibrated by the terminal device is achieved, so that OTA performance under different high-order modulation modes is improved, higher throughput is obtained, and further the uplink transmission rate is improved.
