The power regulation method first obtains a first saturation power corresponding to a power amplifier's power supply voltage Vcc being a first voltage value. If the first saturation power is less than a target threshold, based on the reliability of the power amplifier and the correspondence between the power amplifier's power supply voltage Vcc and the power amplifier's input power, it determines whether to adjust the first voltage value to a second voltage value. Then, the first voltage value is adjusted to the second voltage value. The saturation power when the power amplifier's power supply voltage Vcc is the second voltage value is the second saturation power, which is greater than the first saturation power. That is, when the power amplifier's saturation power is less than the target threshold, a first preset relationship determines whether to adjust the first voltage value to the second voltage value without damaging the power amplifier, thereby ensuring that the terminal device can establish a communication connection with the network device.

Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to a power regulation method and an electronic device. Background Technology

[0002] With the development of communication technology, in some scenarios, the uplink signal power of terminal devices is too low, which can cause the terminal devices to be unable to connect to network devices and thus prevent them from accessing the network normally.

[0003] In this situation, terminal devices typically increase the uplink signal power by increasing the input power or power supply voltage Vcc of the power amplifier (PA) to enable normal connection to network devices. However, if the input power or power supply voltage Vcc of the power amplifier in the terminal device exceeds a corresponding threshold, the power amplifier will fail, thus affecting the normal communication of the terminal device.

[0004] Therefore, improving the uplink signal power of terminal equipment while ensuring that the power amplifier is not damaged has become an urgent problem to be solved. Summary of the Invention

[0005] This application provides a power regulation method and an electronic device that can improve the uplink signal power of the electronic device without damaging the power amplifier.

[0006] In a first aspect, a power regulation method is provided, the method being applied to a terminal device, the terminal device including a power amplifier, the method comprising:

[0007] Obtain the first saturation power, which is the saturation power corresponding to the power amplifier's power supply voltage Vcc being a first voltage value;

[0008] If the first saturation power is less than the target threshold, it is determined whether to adjust the first voltage value to the second voltage value based on the first preset relationship. When the power supply voltage Vcc of the power amplifier is the second voltage value, the saturation power of the power amplifier is the second saturation power, which is greater than the first saturation power. The first preset relationship refers to the correspondence between the reliability of the power amplifier, the power supply voltage Vcc value of the power amplifier, and the input power of the power amplifier.

[0009] The first preset relationship can refer to Figure 7 The curve shown represents the power amplifier's supply voltage Vcc versus input power. Each point on this curve represents the maximum supply voltage Vcc and maximum input power of the power amplifier assuming it is not damaged. Furthermore, the supply voltage Vcc value at each point on the curve can refer to a voltage value greater than the manufacturer's recommended supply voltage Vcc threshold.

[0010] The power adjustment method provided in this application first obtains the first saturated power corresponding to the power amplifier's power supply voltage Vcc being a first voltage value. When the first saturated power is less than a target threshold, based on the reliability of the power amplifier and the correspondence between the power amplifier's power supply voltage Vcc and the power amplifier's input power, it determines whether to adjust the first voltage value to a second voltage value. Then, the first voltage value is adjusted to the second voltage value. When the power amplifier's power supply voltage Vcc is the second voltage value, the power amplifier's saturated power is the second saturated power, which is greater than the first saturated power. That is to say, through the power adjustment method provided in this application, when the power amplifier's saturated power is less than the target threshold, it determines, through a first preset relationship, that the first voltage value is adjusted to the second voltage value without causing damage to the power amplifier, thereby increasing the power amplifier's saturated power and thus increasing the uplink signal power of the terminal device, ensuring that the terminal device can establish a communication connection with the network device.

[0011] In conjunction with the first aspect, in some embodiments of the first aspect, the first voltage value is less than a voltage threshold value.

[0012] The voltage threshold typically refers to the maximum value of the power supply voltage Vcc recommended by the manufacturer. In other words, it represents the maximum saturation power of the power amplifier when the power supply voltage Vcc is at the first voltage value, while ensuring the amplifier's reliability. Although the first voltage value is less than the voltage threshold, it is usually close to it.

[0013] In conjunction with the first aspect, in some embodiments of the first aspect, the second voltage value is greater than a voltage threshold value.

[0014] If, based on the first preset relationship, it is determined that the first voltage value can be adjusted to the second voltage value, then the power amplifier will not be damaged when the power supply voltage Vcc is the second voltage value. In this case, the second saturation power is greater than the first saturation power.

[0015] The power adjustment method provided in this application increases the power amplifier's power supply voltage Vcc from a first voltage value to a second voltage value based on a first preset relationship when the first saturation power of the power amplifier is less than a target threshold. The first voltage value is less than a voltage threshold, and the second voltage value is greater than a voltage threshold. Furthermore, when the power supply voltage Vcc is the second voltage value, there is no risk of damage to the power amplifier. That is, when the first saturation power of the power amplifier is less than the target threshold, the first preset relationship determines that increasing the first voltage value to the second voltage value without causing damage to the power amplifier can improve the saturation power of the power amplifier, thereby increasing the uplink signal power of the terminal device and ensuring that the terminal device can establish a communication connection with the network device.

[0016] In conjunction with the first aspect, in some embodiments of the first aspect, the method further includes: if it is determined based on a first preset relationship that the first voltage value should be adjusted to a second voltage value, then the first voltage value is increased according to a preset step.

[0017] The preset step can refer to a step value determined based on user experience, or it can be a step value obtained by the terminal device through machine learning based on historical data. This application embodiment does not limit this.

[0018] As the power supply voltage Vcc is gradually increased, the change in the saturation power output of the power amplifier can be detected simultaneously. When the saturation power reaches the second saturation power, the voltage adjustment is stopped. The power supply voltage Vcc value at this point is the second voltage value.

[0019] The power adjustment method provided in this application, when the power supply voltage Vcc is a first voltage value and the first saturation power of the power amplifier is less than the target threshold, firstly determines whether to adjust the first voltage value to a second voltage value based on the reliability of the power amplifier, the first preset relationship between the power supply voltage Vcc value and the input power. If it is necessary to adjust the first voltage value to the second voltage value, the first voltage value is gradually increased according to a preset step until the saturation power of the power amplifier is the second saturation power. That is to say, the process of increasing the power supply voltage Vcc in this application embodiment is to gradually increase the power supply voltage Vcc, and each adjustment of the power supply voltage Vcc is based on the first preset relationship to avoid reliability problems of the power amplifier during the adjustment process.

[0020] In conjunction with the first aspect, in some embodiments of the first aspect, increasing the first voltage value according to a preset step includes: increasing the first voltage value according to a preset component until the second saturation power is greater than a target threshold.

[0021] During the gradual increase of the power supply voltage Vcc, the change in the saturation power output of the power amplifier can be detected simultaneously. When the detected saturation power reaches the second saturation power, the voltage adjustment stops. The power supply voltage Vcc value at this point is the second voltage value.

[0022] In conjunction with the first aspect, in some embodiments of the first aspect, the method further includes: if it is determined based on a first preset relationship that the first voltage value will not be adjusted to the second voltage value, then the first voltage value is used as the power supply voltage Vcc of the power amplifier.

[0023] The power adjustment method provided in this application determines whether to increase the power amplifier's power supply voltage Vcc based on a first preset relationship when the first saturation power of the power amplifier is less than the target threshold. If the power supply voltage Vcc cannot be increased, the initial voltage value, i.e., the first voltage value, can be used as the power amplifier's power supply voltage Vcc. In some possible scenarios, such as the production process of terminal equipment, directly using the initial voltage value as the power amplifier's power supply voltage Vcc can avoid the need for terminal equipment maintenance and improve the efficiency of the production of terminal equipment.

[0024] In a second aspect, a power regulation device is provided, including a unit for performing any of the methods in the first aspect. The device may be a terminal device or a chip within a terminal device. The device may include an input unit and a processing unit.

[0025] When the device is a terminal device, the processing unit may be a processor, and the input unit may be a communication interface; the terminal device may also include a memory for storing computer program code, which, when the processor executes the computer program code stored in the memory, causes the terminal device to perform any of the methods in the first aspect.

[0026] When the device is a chip within a terminal device, the processing unit can be an internal processing unit of the chip, and the input unit can be an output interface, pin, or circuit, etc.; the chip may also include a memory, which can be an internal memory of the chip (e.g., a register, cache, etc.) or an external memory (e.g., a read-only memory, random access memory, etc.); the memory is used to store computer program code, and when the processor executes the computer program code stored in the memory, the chip performs any of the methods in the first aspect.

[0027] In one possible implementation, a memory is used to store computer program code; a processor executes the computer program code stored in the memory. When the computer program code stored in the memory is executed, the processor performs the following: acquiring a first saturation power, which is the saturation power corresponding to a first voltage value when the power amplifier's power supply voltage Vcc is at a first voltage value; if the first saturation power is less than a target threshold, determining whether to adjust the first voltage value to a second voltage value based on a first preset relationship; when the power amplifier's power supply voltage Vcc is at the second voltage value, the power amplifier's saturation power is the second saturation power, which is greater than the first saturation power. The first preset relationship refers to the correspondence between the power amplifier's reliability, the power amplifier's power supply voltage Vcc value, and the power amplifier's input power.

[0044] To facilitate understanding, the relevant terms and concepts that may be involved in the embodiments of this application will be introduced below.

[0045] 1. Power amplifier.

[0046] In radio frequency (RF) systems, a power amplifier is a module that amplifies weak signals to ensure that the transmission power meets the requirements. The core function of a power amplifier is to increase signal power, enabling the RF signal to be effectively radiated through the antenna. Generally, power amplifiers are typically transistors.

[0047] 2. Power amplifier power supply voltage Vcc.

[0048] The power amplifier's supply voltage Vcc refers to the power source introduced from the outside, providing the core energy to the amplifier. This energy is typically an internal power supply in the form of DC voltage. Generally, the power amplifier's supply voltage Vcc has a voltage threshold. If the supply voltage Vcc exceeds this threshold, it will cause transistors to burn out, leading to amplifier failure. As long as the supply voltage Vcc does not exceed the voltage threshold, a higher supply voltage Vcc results in higher amplifier gain.

[0049] For example, such as Figure 1 As shown, after the power amplifier applies the power supply voltage Vcc and the input signal, it amplifies the input signal to obtain the output signal.

[0050] 3. Input signal power of the power amplifier (RF Gain Index, RGI).

[0051] The input signal power of a power amplifier refers to the power of the radio frequency signal entering the power amplifier. RGI directly affects the output power and efficiency of the amplifier.

[0052] 4. Saturation power of the power amplifier.

[0053] When the input power of a power amplifier exceeds its input power threshold, the amplifier enters the saturation region, leading to gain compression and signal distortion. The saturation power of a power amplifier can be defined as the power at which the output signal power no longer increases linearly with increasing input power.

[0054] In some cases, such as when the terminal device uses APT tracking mode to regulate the power supply voltage Vcc, the power amplifier may operate in the linear region. With constant gain, the higher the input signal power, the higher the output power. However, when the input power exceeds the input power threshold, the power amplifier will enter the saturation region, leading to gain compression and signal distortion. Further increases in input power may damage the power amplifier. To ensure linear amplification, the input signal power must be controlled within the amplifier's linear operating range.

[0055] In some cases, such as when the terminal device uses DPD tracking mode to regulate the power supply voltage Vcc, the power amplifier operates in the linear region. DPD tracking mode means that for different power supply voltages Vcc, the Mline curve corresponding to those voltages is used to ensure the power amplifier maintains the same linearity at the same compression point. Therefore, in DPD tracking mode, the input power RGI changes with the power supply voltage Vcc. Thus, when increasing the power supply voltage Vcc to improve saturation power, after increasing Vcc, it is necessary to readjust the power supply voltage Vcc based on the current input power RGI until the saturation power requirement is met, or until the maximum value of Vcc is reached.

[0056] For example, the curve between the power of the output signal and the power of the input signal of the power amplifier is as follows: Figure 2 As shown, before point A on the curve, the power of the power amplifier's output signal increases linearly with the increase of the input signal power. After point A on the curve, the power of the power amplifier's output signal no longer increases linearly with the increase of the input power, resulting in gain compression.

[0057] For power amplifiers using APT tracking mode, such as Figure 2 Point A shown is the saturation power. For a power amplifier using DPD tracking mode, the power point corresponding to the maximum supply voltage Vcc when the power amplifier is in saturation is called the saturation power.

[0058] 5. Weak field.

[0059] A weak field, also known as a weak coverage area, typically refers to an area where the signal strength of network devices is below the signal threshold. Common weak fields include enclosed spaces such as tunnels, pits, and mines; underground parking lots; areas obstructed by tall buildings; the edge of base station coverage; and environments with severe electromagnetic interference. Terminal devices located in weak field areas usually need to increase their transmitted signal power to establish a communication connection with network devices.

[0060] With the development of communication technology, network coverage is increasing to meet users' needs for mobile network access anytime, anywhere. However, in some scenarios, such as when a terminal device is in a weak signal area, it is often necessary to increase the terminal device's transmit signal power to establish a communication connection with the network device. In this case, the terminal device can increase the power amplifier's output signal power by increasing the input power or the power supply voltage Vcc. As the power amplifier's output signal power increases, the uplink signal power radiated through the antenna also increases, enabling the terminal device to establish a communication connection with the network device. However, currently, to fully utilize the power amplifier, the power supply voltage Vcc is usually set to a value close to a safe voltage. Increasing the power supply voltage Vcc to increase the uplink signal power can easily lead to power amplifier failure, thus affecting the normal communication of the terminal device.

[0061] In view of this, the present application provides a power adjustment method. When the first saturation power of the power amplifier is less than a target threshold, the power supply voltage Vcc of the power amplifier is increased from a first voltage value to a second voltage value based on a first preset relationship. The first voltage value is a voltage value less than a voltage threshold, and the second voltage value is a voltage value greater than a voltage threshold. Furthermore, when the power supply voltage Vcc is the second voltage value, there is no risk of damage to the power amplifier. That is, when the first saturation power of the power amplifier is less than the target threshold, the first preset relationship determines that increasing the first voltage value to the second voltage value without causing damage to the power amplifier can improve the saturation power of the power amplifier, thereby improving the uplink signal power of the terminal device and ensuring that the terminal device can establish a communication connection with the network device.

[0062] This application provides a power regulation method applied to an electronic device, which can be a terminal device, also known as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. Terminal devices can be mobile phones, smart TVs, wearable devices, tablets, computers with wireless transceiver capabilities, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, etc. The embodiments of this application do not limit the specific technology or device form used in the terminal device.

[0063] Figure 3 This diagram illustrates a possible structure for a terminal device 100, which may include a radio frequency (RF) circuit 10, multiple antennas 15, a processor 16, and a memory 17. The RF circuit 10 includes a baseband chip 11, a radio frequency integrated circuit (RFIC) 12, an RF front-end 13, and a MIPI driver 14. The MIPI driver 14 can be a standalone device, integrated into the RFIC 12, or integrated with the baseband chip 11 and the processor 16 in a system-on-chip (SoC).

[0064] The processor 16 involved in this application embodiment can be a chip. For example, it can be a field-programmable gate array (FPGA), an application-specific integrated circuit (ASIC), a central processor unit (CPU), a network processor (NP), a digital signal processor (DSP), a microcontroller unit (MCU), a programmable logic device (PLD), or other integrated chips. The processor 16 can also be called an application processor (AP). The processor 16 can receive data from or transmit data through the radio frequency circuit 10.

[0065] The memory 17 involved in the embodiments of this application can be volatile memory or non-volatile memory, or may include both volatile and non-volatile memory. The non-volatile memory can be read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), or flash memory. The volatile memory can be random access memory (RAM), which is used as an external cache. By way of example, but not limitation, many forms of RAM are available, such as static random access memory (SRAM), dynamic random access memory (DRAM), synchronous dynamic random access memory (SDRAM), double data rate synchronous dynamic random access memory (DDR SDRAM), enhanced synchronous dynamic random access memory (ESDRAM), synchronous linked dynamic random access memory (SLDRAM), and direct rambus RAM (DR RAM). It should be noted that the memory used in the systems and methods described herein is intended to include, but is not limited to, these and any other suitable types of memory.

[0066] The radio frequency circuit 10 can realize wireless communication technologies such as 2nd generation (2G), 3rd generation (3G), 4th generation (4G), and 5th generation (5G). The radio frequency circuit 10 can also provide wireless communication technologies applicable to the terminal device 100, including wireless local area networks (WLANs) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), and near field communication (NFC).

[0067] In the RF circuit 10, the RF front-end 13 includes multiple LNAs, power amplifiers (PAs), RF front-end switches, and other devices. The LNAs are used to amplify the RF signals received by the receiving channel, the PAs are used to amplify the RF signals transmitted by the transmitting channel, and the filters are used to filter the RF signals.

[0068] The baseband chip 11, also known as a modem, is used for modulation and demodulation of baseband signals, digital filtering, equalization processing, and also for controlling devices in the RF front-end via the MIPI driver 14. Figure 4 As shown, the MIPI driver 14 is connected to various devices in the RF front-end 13 (such as the aforementioned PA, LNA, and RF front-end switch) via the MIPI RFFE bus, thereby controlling the various devices in the RF front-end 13. The RFIC 12 is used to convert the baseband signal from the baseband chip 11 into an RF signal, which is then transmitted through the RF front-end 13 and the antenna 15. Alternatively, it receives the RF signal through the antenna 15 and the RF front-end 13, converts it into a baseband signal, and sends it to the baseband chip 11. The memory 17 can store computer program instructions for execution by the controller (e.g., the baseband chip 11, the processor 16). The MIPI driver 14 also includes a memory for storing computer program instructions for execution by the MIPI driver 14, thereby executing the bus driving method involved in the embodiments of this application.

[0069] In the traditional control scheme for LNA gain updates, the MIPI driver 14 sends a gain control command to the LNA of each receiving channel via the MIPI RFFE bus in each subframe. The gain control command is used to set the gain of the LNA, thereby performing automatic gain control (AGC) on the LNA to adapt to changes in the communication network.

[0070] In some possible cases, the MIPI driver 14 can also be located inside the baseband chip 11, and the MIPI driver 14 sends control signals to the RF front-end 13 through the baseband chip 11.

[0071] The application scenarios of the embodiments of this application will be briefly described below.

[0072] The power regulation method of this application can be applied to terminal equipment using power amplifiers. By adjusting the power supply voltage Vcc of the power amplifier, the output power of the power amplifier can be increased while ensuring the reliability of the power amplifier.

[0073] Application Scenario 1: Improving the performance of terminal devices during the production process.

[0074] For example, the power regulation method provided in this application embodiment can be applied to the production process of terminal equipment. By adjusting the power amplifier's power supply voltage Vcc and input power, the gain of the power amplifier can be increased while ensuring its reliability, thereby improving the performance of the power terminal equipment.

[0075] Application Scenario 2: Increase the output power when the terminal device is in a weak field area so that the terminal device can communicate normally with the network device.

[0076] For example, the power adjustment method provided in this application embodiment can be applied to scenarios where the terminal device is in a weak field area. By adjusting the power amplifier's power supply voltage Vcc and input power, the gain of the power amplifier is increased while ensuring its reliability. This allows the terminal device in a weak field area to establish a communication connection with the network device, thus ensuring the user's communication function in a weak field area.

[0077] For example, such as Figure 5 As shown, when a user carries mobile phone 100 into a relatively enclosed room, the signal path attenuation of base station 200 is significantly affected by the room walls, causing mobile phone 100 to be unable to establish a communication connection with base station 200. In this case, the power adjustment method provided in this application embodiment can be used to increase the gain of the power amplifier while ensuring the reliability of the power amplifier, thereby enabling mobile phone 100 in an enclosed room to establish a communication connection with base station 200.

[0078] It should be understood that the above are illustrative examples of application scenarios and do not limit the application scenarios of this application in any way.

[0079] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0080] Figure 6 This is a schematic flowchart of a power regulation method provided in an embodiment of this application, as shown below. Figure 6 As shown, the method includes:

[0081] S101. Obtain the first saturation power, which is the saturation power corresponding to the power amplifier's power supply voltage Vcc being a first voltage value.

[0082] The first saturation power can refer to the saturation power corresponding to the power amplifier when the power supply voltage Vcc is at a first voltage value. The first voltage value can refer to the initial voltage value of the power amplifier's power supply voltage Vcc. The initial voltage value of the power amplifier's power supply voltage Vcc (i.e., the first voltage value) usually refers to the optimal power supply voltage Vcc obtained through debugging by R&D personnel. That is to say, under the condition that the power amplifier's power supply voltage Vcc is at the first voltage value, it represents the maximum saturation power of the power amplifier while ensuring its reliability. The maximum saturation power of the power amplifier can mean that the power amplifier has the strongest signal amplification capability.

[0083] It should be noted that, as Figure 1 and Figure 2 As shown, a power amplifier, with a applied power supply voltage Vcc, amplifies the input signal to obtain an amplified output signal. The saturation power of the power amplifier varies depending on the applied power supply voltage Vcc. A higher power supply voltage Vcc results in higher saturation power and a higher gain, leading to maximum output power when the input signal power is at its maximum. However, if the power supply voltage Vcc exceeds a voltage threshold, the power amplifier may fail. Therefore, assuming the power amplifier's reliability, the maximum saturation power can be defined as the maximum saturation power achieved when the power supply voltage Vcc does not exceed the aforementioned voltage threshold.

[0084] For example, as shown in Table 1, the saturation power of the power amplifier increases as the power supply voltage Vcc and the input signal power increase.

[0085] Table 1

[0086]

[0087] To prevent power amplifier failure, manufacturers typically recommend the aforementioned voltage thresholds. However, with increasingly demanding communication quality requirements, the applied power supply voltage (Vcc) is often quite high during power amplifier operation, approaching these thresholds. Simply increasing the power supply voltage (Vcc) to increase the power amplifier's saturation power carries the risk of amplifier damage.

[0088] S102. If the first saturation power is less than the target threshold, determine whether to adjust the first voltage value to the second voltage value based on the first preset relationship. When the power supply voltage Vcc of the power amplifier is the second voltage value, the saturation power of the power amplifier is the second saturation power. The second saturation power is greater than the first saturation power. The first preset relationship refers to the correspondence between the reliability of the power amplifier, the power supply voltage Vcc value of the power amplifier and the input power of the power amplifier.

[0089] It should be noted that power amplifiers are typically components in terminal devices. The amplified input signal obtained through the power amplifier usually requires antenna radiation to establish a communication connection with network devices. Energy loss occurs along the path between the power amplifier and the antenna, resulting in a reduction in the power of the power amplifier's output signal. This necessitates that the power of the power amplifier's output signal be greater than the transmit signal power of the terminal device to meet its specifications, further increasing the minimum requirement for the power amplifier's saturation power.

[0090] The target threshold, also known as the target saturation power, refers to the minimum saturation power of the power amplifier. If the first saturation power is greater than or equal to the target threshold, the amplified output signal transmitted to the antenna and radiated outwards can communicate normally with network devices. If the first saturation power is less than the target threshold, the signal power transmitted to the antenna and radiated outwards is too low to communicate normally with network devices.

[0091] For example, during the testing of a terminal device, in order to ensure normal communication with a network device, the requirement for the saturation power index of the power amplifier in the terminal device can be the target output signal power in Table 2. Usually, the terminal device will set a relatively high target output signal power to ensure that in various extreme scenarios, the saturation power of the terminal device can meet the requirements and normal communication with the network device can be achieved. Further, temperature and frequency changes also affect the saturation power of the terminal device. Considering the influence of temperature and frequency on saturation power, temperature compensation and frequency compensation are added to the target output signal power to obtain the target saturation power shown in Table 2, so as to meet the normal communication with the network device. For example, the target saturation power corresponding to antenna ANT4 in frequency band B1 is obtained by adding 1 dB of temperature compensation and frequency compensation to the target output signal power. As shown in Table 2, during the production of the terminal device, the performance of multiple terminal devices is tested, and the test data is statistically analyzed to obtain the measured values of the saturation power of the power amplifier, including the measured maximum value, the measured average value, and the measured minimum value. It can be seen from Table 2 that the measured values of the saturation power of the power amplifier are all less than the target saturation power (equivalent to the above-mentioned target threshold). This will result in the performance of the terminal device not meeting the requirements and affect the communication between the terminal device and the network device in extreme scenarios.

[0092] Table 2

[0093]

[0094] It can be understood that the first voltage value usually refers to the voltage value that meets the voltage threshold recommended by the manufacturer, while the second voltage value usually refers to the voltage value that does not meet the voltage threshold recommended by the manufacturer. For example, the first voltage value is V1 and the second voltage value is V2, where V1 < V < V2, and V is the threshold of the power supply voltage Vcc recommended by the manufacturer.

[0095] The first preset relationship can refer to the corresponding relationship among the power supply voltage Vcc value of the power amplifier, the input power of the power amplifier, and the reliability of the power amplifier obtained through testing. For example, the first preset relationship is a curve formed by the maximum input power and the maximum power supply Vcc corresponding to the power amplifier when it is damaged. The abscissa of this curve is the power supply voltage Vcc of the power amplifier, and the ordinate is the input power of the power amplifier. That is, if the coordinate point determined by the input power and the power supply voltage is below this curve, the power amplifier will not be damaged; if the coordinate point determined by the input power and the power supply voltage is above this curve or on this curve, the power amplifier will be damaged. Based on the curve corresponding to the first preset relationship, by increasing the power supply voltage Vcc, when the coordinate point determined by the input power and the power supply voltage Vcc is below the curve corresponding to the first preset relationship, the saturation power can be appropriately increased on the premise of ensuring that the power amplifier is not damaged.

[0096] For example, such as Figure 7 As shown, tests were conducted using multiple power amplifiers to obtain a curve representing the first preset relationship. The horizontal axis represents the power amplifier's supply voltage (Vcc), and the vertical axis represents the power amplifier's input power. Any point on curve 11 represents the maximum supply voltage (Vcc) and maximum input power value corresponding to the power amplifier failure. It is understood that different power amplifiers will produce different curves for the first preset relationship; testing is required to obtain this curve.

[0097] Point B on curve 11 indicates that the power amplifier will fail when the power supply voltage Vcc is 4V and the input power is 26dBm. However, when the input power is less than 26dBm, for example, when the input power is 25.5dBm and the power supply voltage Vcc is still 4V, the power amplifier will not fail.

[0098] It is understandable that, with a constant input power, a higher power supply voltage (Vcc) results in a higher saturation power of the power amplifier. Therefore, after determining the input power of the power amplifier, a first preset relationship can be used to determine whether appropriately increasing the power supply voltage (Vcc) will damage the power amplifier, i.e., whether there is a margin in the power supply voltage (Vcc). If there is a margin in the power supply voltage (Vcc), then increasing the power supply voltage (Vcc) can improve the saturation power of the power amplifier.

[0099] based on Figure 7 The curve corresponding to the first preset relationship shown can be used to obtain the corresponding relationship table shown in Table 3. That is, the input power and power supply voltage Vcc at the coordinate points below the curve corresponding to the first preset relationship can generate the data in Table 3. When the input power and power supply voltage Vcc of the power amplifier are the same as the set of data in Table 3, the power amplifier will not be damaged. For example, when the input power RGI=47 and the power supply voltage Vcc is 2476mV, the corresponding saturation power is 22.4dBm, and the power amplifier will not be damaged. Here, input power can refer to the power value output by the RF chip; different power values ​​correspond to different input powers of the power amplifier. For example, if the output power RGI of the RF chip is 47, the corresponding input power of the power amplifier is 0dBm; if the output power RGI of the RF chip is 50, the corresponding input power of the power amplifier is 3dBm.

[0100] Table 3

[0101]

[0102] As shown in Table 3, with the same input power, a higher supply voltage Vcc results in a higher saturation power. For example, as shown in Table 3, with an input power RGI=50 and a supply voltage Vcc of 3053mV, the corresponding saturation power is 24.4dBm; with an input power RGI=50 and a supply voltage Vcc of 3220mV, the corresponding saturation power is 24.9dBm. Furthermore, in both of these cases, the power amplifier will not be damaged. As another example, with an input power RGI=56 and a supply voltage Vcc of 4696mV, the corresponding saturation power is 28.4dBm; with an input power RGI=56 and a supply voltage Vcc of 4960mV, the corresponding saturation power is 28.9dBm. Again, in both of these cases, the power amplifier will not be damaged.

[0103] With a power amplifier supply voltage Vcc threshold of 3.1V and a target saturation power of 24.8dBm, as shown in Table 3, the power amplifier supply voltage Vcc at the first voltage value (3053mV) results in a first saturation power of 24.4dBm. This is equivalent to the power amplifier's first saturation power being less than the target threshold. In this case, the power amplifier supply voltage Vcc can be adjusted to a second voltage value, for example, 3220mV as shown in Table 3, which is greater than the manufacturer's recommended threshold without damaging the power amplifier. In this case, the power amplifier's second saturation power is 24.9dBm, which is greater than the target threshold, thus meeting the power amplifier's saturation power requirement. Since the data in Table 3 is based on... Figure 7 The curve corresponding to the first preset relationship is shown. Therefore, loading the power amplifier with the power supply voltage Vcc and input power as shown in Table 3 will not cause damage to the power amplifier.

[0104] The power adjustment method provided in this application first obtains the first saturated power corresponding to the power amplifier's power supply voltage Vcc being a first voltage value. When the first saturated power is less than a target threshold, based on the reliability of the power amplifier and the correspondence between the power amplifier's power supply voltage Vcc and the power amplifier's input power, it determines whether to adjust the first voltage value to a second voltage value. Then, the first voltage value is adjusted to the second voltage value. When the power amplifier's power supply voltage Vcc is the second voltage value, the power amplifier's saturated power is the second saturated power, which is greater than the first saturated power. That is to say, through the power adjustment method provided in this application, when the power amplifier's saturated power is less than the target threshold, it determines, through a first preset relationship, that the first voltage value is adjusted to the second voltage value without causing damage to the power amplifier, thereby increasing the power amplifier's saturated power and thus increasing the uplink signal power of the terminal device, ensuring that the terminal device can establish a communication connection with the network device.

[0105] Optionally, the first voltage value may be less than the voltage threshold, and the second voltage value may be greater than the voltage threshold.

[0106] As described above, the first voltage value typically refers to the optimal power supply voltage Vcc obtained through adjustments by R&D personnel. In other words, when the power amplifier's power supply voltage Vcc is at the first voltage value, it usually refers to a voltage value that does not exceed the manufacturer's recommended voltage threshold. That is, under the premise of ensuring the reliability of the power amplifier, the maximum saturation power of the power amplifier when the power supply voltage Vcc is at the first voltage value is the optimal value. Adjusting the first voltage value to a second voltage value is usually determined based on the reliability of the power amplifier, a first preset relationship between the power amplifier's power supply voltage Vcc value, and the power amplifier's input power. For example, as... Figure 7 As shown, the first preset relationship refers to the curve between the maximum power supply voltage Vcc and the maximum input power of the power amplifier when the power amplifier is damaged. In other words, if it is determined based on the first preset relationship that the first voltage value can be adjusted to the second voltage value, then the power amplifier will not be damaged when the power supply voltage Vcc is at the second voltage value. In this case, if the second saturation power is greater than the first saturation power, it means that the second voltage value is greater than the first voltage value. Although the first voltage value is less than the voltage threshold, it is usually close to the voltage threshold. In this case, if the second voltage value is greater than the voltage threshold, the saturation power will be higher, better meeting user needs. Therefore, the second voltage value can refer to a voltage value greater than the voltage threshold.

[0107] The power adjustment method provided in this application increases the power amplifier's power supply voltage Vcc from a first voltage value to a second voltage value based on a first preset relationship when the first saturation power of the power amplifier is less than a target threshold. The first voltage value is less than a voltage threshold, and the second voltage value is greater than a voltage threshold. Furthermore, when the power supply voltage Vcc is the second voltage value, there is no risk of damage to the power amplifier. That is, when the first saturation power of the power amplifier is less than the target threshold, the first preset relationship determines that increasing the first voltage value to the second voltage value without causing damage to the power amplifier can improve the saturation power of the power amplifier, thereby increasing the uplink signal power of the terminal device and ensuring that the terminal device can establish a communication connection with the network device.

[0108] In some possible scenarios, the power adjustment method provided in this application can be applied to situations where the terminal device is in a weak field region. In this case, the process of adjusting the first voltage value to the second voltage value can refer to gradually adjusting the first voltage value to the second voltage value according to a preset step. This can reduce the probability of power amplifier failure caused by increasing the first voltage value too much at once. The following describes... Figure 8 The embodiments shown are described below.

[0109] Figure 8 This is a flowchart illustrating a power regulation method provided in an embodiment of this application, as shown below. Figure 8 As shown, the method includes:

[0110] S201. Obtain the first saturation power, which is the saturation power corresponding to the power amplifier's power supply voltage Vcc being a first voltage value.

[0111] The specific process of obtaining the first saturation power, which is the saturation power corresponding to the power amplifier's power supply voltage Vcc being the first voltage value, can be found in the steps shown in S101 above, and will not be repeated here.

[0112] S202. If the first saturation power is less than the target threshold, determine whether to adjust the first voltage value to the second voltage value based on the first preset relationship. When the power supply voltage Vcc of the power amplifier is the second voltage value, the saturation power of the power amplifier is the second saturation power. The second saturation power is greater than or equal to the target threshold. The first preset relationship refers to the correspondence between the reliability of the power amplifier, the power supply voltage Vcc value of the power amplifier and the input power of the power amplifier.

[0113] The specific process of determining whether to adjust the first voltage value to the second voltage value based on the first preset relationship can be found in the description of S102, and will not be repeated here.

[0114] S203. Increase the first voltage value according to the preset step until the saturation power of the power amplifier is the second saturation power.

[0115] The preset step can refer to a step value determined based on user experience, or it can be a step value obtained by the terminal device through machine learning based on historical data. This application embodiment does not limit this.

[0116] As the power supply voltage Vcc is gradually increased, the change in the saturation power output of the power amplifier can be detected simultaneously. Voltage adjustment stops when the detected saturation power reaches the second saturation power. The current power supply voltage Vcc value is the second voltage value. Each adjustment of the power supply voltage Vcc is based on a first preset relationship to avoid reliability issues with the power amplifier. This allows for maximizing the saturation power of the power amplifier while ensuring its reliability.

[0117] For example, the preset step can refer to a value determined based on user experience. The first voltage value is 3.0V, the initial second voltage value is 3.3V, and the preset step can be 0.1V. During the process of increasing the first voltage value, it can be first increased to 3.1V, and then the saturation power of the power amplifier is measured to see if it matches the second saturation power. If the measured saturation power is less than the target threshold, then the current saturation power is not the second saturation power, and the power supply voltage Vcc is further increased by 0.1V to 3.2V. Then, the saturation power of the power amplifier is measured again to see if it matches the second saturation power. If the saturation power of the power amplifier is greater than the target threshold and matches the second saturation power, then 3.2V can be used as the updated second voltage value, and the power supply voltage Vcc of the power amplifier can be set to 3.2V for operation.

[0118] Understandably, during the process of increasing the initial voltage value of the power supply voltage Vcc, the adjusted power supply voltage Vcc cannot exceed its upper limit, such as the maximum value of Vcc on the curve corresponding to the first preset relationship. In some possible cases, the upper limit of the power supply voltage Vcc can also be the maximum value obtained by retaining a margin based on the power supply voltage Vcc on the curve corresponding to the first preset relationship. For example, if the power supply voltage Vcc on the curve corresponding to the first preset relationship is 4V, to further improve the reliability of the power amplifier, 0.2V can be subtracted from 4V to obtain 3.8V, which can be used as the upper limit of the power supply voltage Vcc.

[0119] As described in S102, the first preset relationship refers to the correspondence between the power amplifier's supply voltage Vcc value, input power, and reliability obtained through testing. Based on this first preset relationship, a curve showing the relationship between the input power and the supply voltage Vcc at the time of power amplifier failure can be obtained. Figure 7 Curve 11 in the diagram. These values ​​can then be written into the terminal device so that the terminal device can determine the power amplifier's supply voltage Vcc based on these values.

[0120] For example, the data written to the terminal device can be... Figure 8 The data format shown is a key-value pair (Name-Value, NV) structure. For example... Figure 8 As shown, the NV format includes the following keys: "Signal Path", "Device", "Frequency Synthesis Method", "Antenna", "Network Standard", "Frequency Band", "Sub-Band", "NRD Status", "Transmit Channel - CAL", "Input Signal RGI", "Input Signal PAIN", and "Power Supply Voltage Vcc". Specifically, the values ​​for "Input Signal RGI" are 60, 59, 58, 57, 56, 55...46, 45; the values ​​for "Input Signal PAIN" are 6.9, 6.1,..., -6; and the values ​​for "Power Supply Voltage Vcc" are 3.4, 3.5, 3.6, 3.7, 3.8, 3.8,..., 3.8, 3.8.

[0121] The following explanation uses a preset step size of 0.1V and an upper limit for the power supply voltage Vcc of 3.8V as an example. Figure 9 As shown, the input signal RGI is 60 and the power supply voltage Vcc is 3.4V, indicating that the upper limit of the power supply voltage of the power amplifier is 3.4V when the input signal RGI is 60.

[0122] Understandably, the RGI of a power amplifier varies across different frequency bands. In some cases, when the input signal RGI of the power amplifier is 55, the upper limit of the corresponding power supply voltage is 3.8V. At the current moment, the first voltage value is 3.4V, and the first saturation power is less than the target threshold. In this case, the first voltage value can be increased by 3.8 - 3.4 = 0.4V. The terminal device can gradually increase the first voltage value in 0.1V increments. When the second saturation power of the power amplifier is greater than or equal to the target threshold, the increase in the first voltage value stops, and this second voltage value becomes the second voltage value. If the power supply voltage increases to 3.8V and the saturation power of the power amplifier is still less than the target threshold, the increase in the power supply voltage will stop, 3.8V will be used as the second voltage value, and the saturation power corresponding to 3.8V will be written to the terminal device as the second saturation power.

[0123] The power adjustment method provided in this application, when the power supply voltage Vcc is a first voltage value and the first saturation power of the power amplifier is less than the target threshold, firstly determines whether to adjust the first voltage value to a second voltage value based on the reliability of the power amplifier, the first preset relationship between the power supply voltage Vcc value and the input power. If it is necessary to adjust the first voltage value to the second voltage value, the first voltage value is gradually increased according to a preset step until the saturation power of the power amplifier is the second saturation power. That is to say, the process of increasing the power supply voltage Vcc in this application embodiment is to gradually increase the power supply voltage Vcc, and each adjustment of the power supply voltage Vcc is based on the first preset relationship to avoid reliability problems of the power amplifier during the adjustment process.

[0124] In some possible cases, the power regulation method provided in this application embodiment can be applied in the production process of terminal equipment. During the production of terminal equipment, it is usually necessary to test the performance of the terminal equipment. If the performance data obtained from the test does not meet the requirements, for example, if the saturation power of the power amplifier is less than the target threshold, the terminal equipment needs to be repaired or scrapped, resulting in reduced production efficiency. In this case, due to individual differences in power amplifiers, some power amplifiers can meet the preset requirements for saturation power when the power supply voltage Vcc is the initial voltage value (equivalent to the first voltage value). Therefore, the first voltage value can be directly used as the input signal parameter of the power amplifier, thereby improving the efficiency of the production terminal equipment. The following describes... Figure 10 The embodiments shown are described below.

[0125] Figure 10 This is a flowchart illustrating a power regulation method provided in an embodiment of this application, as shown below. Figure 10 As shown, the method includes:

[0126] S301. Obtain the first saturation power, which is the saturation power corresponding to the power amplifier's power supply voltage Vcc being a first voltage value.

[0127] The specific process of obtaining the first saturation power, which is the saturation power corresponding to the power amplifier's power supply voltage Vcc being the first voltage value, can be found in the steps shown in S101 above, and will not be repeated here.

[0128] S302. If the first saturation power is less than the target threshold, determine whether to adjust the first voltage value to the second voltage value based on the first preset relationship. When the input signal parameter of the power amplifier is the second voltage value, the saturation power of the power amplifier is the second saturation power, which is greater than the first saturation power. The first preset relationship refers to the correspondence between the reliability of the power amplifier, the power supply voltage Vcc value of the power amplifier, and the input power of the power amplifier.

[0129] The specific process of determining whether to adjust the first voltage value to the second voltage value based on the first preset relationship can be found in the description of S102, and will not be repeated here.

[0130] If it is determined that the first voltage value will be adjusted to the second voltage value, the first voltage value will be increased according to the preset step until it is increased to the second voltage value, which is to execute S303.

[0131] If it is determined that the first voltage value will not be adjusted to the second voltage value, then the first voltage value will be used as the power amplifier's power supply voltage Vcc, which is to execute S304.

[0132] S303. Increase the first voltage value according to the preset step until the saturation power of the power amplifier is the second saturation power.

[0133] The specific process of increasing the first voltage value according to the preset steps until the saturation power of the power amplifier is the second saturation power can be found in the description of S203 above, and will not be repeated here.

[0134] S304. Use the first voltage value as the power amplifier's power supply voltage Vcc.

[0135] Using the first voltage value as the power amplifier's supply voltage Vcc means directly using the initial voltage value as the supply voltage Vcc, thus eliminating the need to adjust the power amplifier's supply voltage Vcc and improving the efficiency of production terminal equipment.

[0136] The power adjustment method provided in this application determines whether to increase the power amplifier's power supply voltage Vcc based on a first preset relationship when the first saturation power of the power amplifier is less than the target threshold. If the power supply voltage Vcc cannot be increased, the initial voltage value, i.e., the first voltage value, can be used as the power amplifier's power supply voltage Vcc. In some possible scenarios, such as the production process of terminal equipment, directly using the initial voltage value as the power amplifier's power supply voltage Vcc can avoid the need for terminal equipment maintenance and improve the efficiency of the production of terminal equipment.

When the power amplifier's power supply voltage Vcc is the second voltage value, the power amplifier's saturation power is the second saturation power, which is greater than the first saturation power. The first preset relationship refers to the correspondence between the power amplifier's reliability, the power amplifier's power supply voltage Vcc value, and the power amplifier's input power.
