The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the examples of this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
For convenience of understanding, a practical use scenario of the transmit power calibration method provided by the present application is described. As shown in fig. 1, in an actual scenario, a terminal involved in transmit power calibration provided in the embodiment of the present application includes: the terminal to be calibrated and the first control terminal. The first control terminal is used for calibrating the transmitting power of the terminal to be calibrated. The embodiment of the present application does not limit the specific terminal types of the first control terminal and the terminal to be calibrated. In a specific implementation process, the first control terminal may be, for example, a combination of a comprehensive tester and a computer terminal; the terminal to be calibrated can be a mobile phone terminal.
Further, as shown in fig. 2, the terminal to be calibrated may include a baseband chip, a radio frequency chip, a power amplifier, and a switch.
The baseband chip is connected with the radio frequency chip, the radio frequency chip is connected with the power amplifier, and the power amplifier is connected with the switch. The baseband chip can be used for generating an initial signal and outputting the initial signal to the radio frequency chip. The radio frequency chip may be configured to generate a first signal based on the initial signal and output the first signal to the power amplifier. The power amplifier can be used for performing power amplification on the first signal to obtain a second signal of which the transmission power meets the signal transmission requirement of the terminal to be calibrated. The switch may be operable to set the current state to a transmit state to enable the second signal to complete transmission.
Fig. 3 is a flowchart of a transmit power calibration method according to an embodiment of the present disclosure. As shown in fig. 3, the method for calibrating the transmission power may include:
In the embodiment of the present application, a baseband chip of a terminal to be calibrated may provide a Mobile Industry Processor Interface (MIPI). The first control terminal can send the gain adjustment parameter to the baseband chip through the MIPI interface of the baseband chip. The gain adjustment parameter can be used for adjusting the gain of the power amplifier of the terminal to be calibrated, so that the power of the output signal of the power amplifier is changed, and the calibration of the transmitting power of the terminal to be calibrated is further realized. The value of the gain adjustment parameter can be set by the first control terminal according to the actual need in the calibration process. In particular, the gain adjustment parameter may be set to 0, for example, when the calibration is performed for the first time, i.e., the current gain of the power amplifier may be kept unchanged during the first calibration.
And 102, receiving the gain adjustment parameter by a baseband chip of the terminal to be calibrated, and sending the gain adjustment parameter to a power amplifier of the terminal to be calibrated.
And 103, determining the configuration gain by the power amplifier according to the gain adjustment parameter.
In the embodiment of the present application, the power amplifier may include a register therein, and the register may be used to store the gain parameter of the power amplifier. After receiving the gain adjustment parameter, the power amplifier may adjust the gain parameter stored in the register, thereby obtaining the configured gain. The method comprises the steps that under the condition that the transmitting power of a terminal to be calibrated is calibrated for the first time, a gain parameter stored in a register can be the configuration gain of a power amplifier when the terminal to be calibrated leaves a factory; in the nth calibration case, the gain parameter stored in the register may be a configured gain determined by the power amplifier according to the gain adjustment parameter received last time when the calibration was performed last time. Wherein N is an integer greater than 1.
And 104, the power amplifier performs power amplification on the first signal according to the configuration gain to generate a second signal, and sends the second signal to the first control terminal.
Step 105 the first control terminal determines the actual gain of the power amplifier based on the received second signal.
In the embodiment of the application, due to a generation error existing in a material production process or signal interference in a signal transmission process, an actual gain of the power amplifier may deviate from a target gain. Thus, the first control terminal may determine the actual gain of the power amplifier from the second signal after receiving the second signal.
First, the second signal may be signal demodulated to determine a second power of the second signal.
The actual gain of the power amplifier may then be determined based on the second power and the first power of the first signal.
At this time, the first control terminal may determine whether the actual gain is consistent with the target gain. Wherein the target gain refers to a gain that the user desires to achieve.
In one possible implementation, the actual gain is consistent with the target gain, indicating that the actual gain has satisfied the gain that the user desires to achieve. At this time, the calibration of the transmission power of the terminal to be calibrated may be stopped.
In another possible implementation, the actual gain is not consistent with the target gain, which indicates that the actual gain does not satisfy the gain that the user desires to achieve. At this time, the first control terminal may determine a gain adjustment value according to the actual gain and the target gain, and send the gain adjustment value as a gain adjustment parameter to the baseband chip to continue to calibrate the transmission power of the terminal to be calibrated. In this implementation manner, the above steps may be repeated, and the terminal to be calibrated is calibrated for multiple times until the determined actual gain of the power amplifier is equal to the target gain.
When the first control terminal determines the gain adjustment value based on the actual gain and the target gain, the following procedure may be performed.
According to the formula T ═ G1-G2A gain adjustment value is determined. Wherein T is a gain adjustment value, G1To target gain, G2Is the actual gain.
In the embodiment of the application, after the gain calibration of the power amplifier is completed, other components on a signal transmission link of the terminal to be calibrated, such as a baseband chip, a radio frequency chip and the like, can be calibrated, so that the accuracy of the transmission power calibration is further improved. The specific calibration method is the prior art, and details are not described in the embodiments of the present application.
In the embodiment of the application, the gain value of the power amplifier of the terminal to be calibrated can be adjusted through the gain adjustment parameter, so that the signal power of the output signal of the power amplifier is changed, the transmitting power of the terminal to be calibrated is calibrated, and the calibration range of the transmitting power is expanded. In addition, the gain adjustment parameter value can be set for multiple times, so that the gain of the power amplifier is changed for multiple times, and the calibration accuracy is improved through multiple times of calibration.
In another embodiment of the present application, as shown in fig. 4, before the step 104, the following steps may be further included:
and step 1031, the first control terminal sends the first transmission parameter and the second transmission parameter to a baseband chip of the terminal to be calibrated.
In the embodiment of the present application, after receiving the first transmission parameter and the second transmission parameter, the baseband chip may first set a parameter value of its initial power according to the first transmission parameter, so as to determine the signal power of the initial signal to be generated. Secondly, the baseband chip can also send the second transmission parameter to the radio frequency chip.
In this embodiment of the application, after the radio frequency chip receives the second transmission parameter, a parameter value of the first power of the radio frequency chip may be set according to the second transmission parameter, so as to determine the signal power of the first signal generated according to the initial signal after receiving the initial signal transmitted by the baseband chip.
Step 1032, the first control terminal sends a transmission instruction to the baseband chip.
In the embodiment of the application, after the gain adjustment parameters and the transmission parameters of the terminal to be calibrated are configured, the first control terminal may send a transmission instruction to the baseband chip of the terminal to be calibrated, so that the terminal to be calibrated transmits signals according to the configured parameters.
Specifically, the baseband chip may generate an initial signal according to the configured initial power in response to the received transmission instruction, and output the initial signal to the radio frequency chip of the terminal to be calibrated. After the rf chip receives the initial signal, the rf chip may further generate a first signal based on the initial signal according to the configured first power, and output the first signal to the power amplifier of the terminal to be calibrated, so that step 104 may be executed, where the power amplifier performs power amplification on the first signal according to the configured gain to generate a second signal.
In the embodiment of the present application, the execution order of step 1031 and step 101 is not limited.
In a possible implementation manner, step 1031 and step 101 are executed simultaneously, that is, the first control terminal may send the gain adjustment parameter, the first transmission parameter, and the second transmission parameter to the baseband chip of the terminal to be calibrated simultaneously. Then, the baseband chip sends the gain adjustment parameter to the power amplifier, sends the second transmission parameter to the radio frequency chip, and sets the parameter value of the initial power according to the first transmission parameter.
In another possible implementation manner, the first control terminal may first execute step 101, and send the gain adjustment parameter to the baseband chip, and the baseband chip sends the gain adjustment parameter to the power amplifier, and then the power amplifier may determine the configured gain according to the gain adjustment parameter. At this time, the first control terminal performs step 1031 to send the first transmission parameter and the second transmission parameter to the baseband chip of the terminal to be calibrated.
In another possible implementation manner, the first control terminal may further perform step 1031, and after the baseband chip and the radio frequency chip set the initial power and the first power according to the received first transmission parameter and the second transmission parameter, the first control terminal performs step 101 to send the gain adjustment parameter to the baseband chip of the terminal to be calibrated.
In any of the above implementations, the execution order of step 1032 is after any of the above steps 101 and 1031.
In the embodiment of the application, the emission parameters of each part of the terminal to be calibrated can be configured according to the requirement of the actual calibration process, so that the emission power under each emission parameter can be calibrated, and the accuracy of emission power calibration is further improved.
In another embodiment of the present application, for convenience of understanding, a specific implementation process is taken as an example, and the implementation manner of the step 105 is further described.
In the embodiment of the present application, the first control terminal may include, for example, a comprehensive test instrument and a data processing terminal.
Firstly, the comprehensive test instrument can receive a second signal output by a power amplifier of a terminal to be calibrated, and demodulate the second signal to obtain a second power. The integrated test meter may transmit the determined second power to the data processing terminal.
Then, after the data processing terminal receives the second power sent by the comprehensive test instrument, the actual gain of the power amplifier can be determined according to the second power and the first power of the first signal before power amplification.
Further, the data processing terminal can also determine whether to continue calibration according to the magnitude relation between the actual gain and the target gain.
When the determined actual gain is not equal to the target gain, the data processing terminal can determine a new gain adjustment parameter again, and sends the new gain adjustment parameter to the baseband chip, and the baseband chip sends the new gain adjustment parameter to the power amplifier. Furthermore, the power amplifier can adjust the configured gain again according to the new gain adjustment parameter, determine the new configured gain, and perform power amplification on the first signal sent by the radio frequency chip again according to the new configured gain. And the data processing terminal receives the second signal obtained after the power amplification of the first signal again, and determines the actual gain of the power amplifier according to the second signal.
In the embodiment of the present application, the above steps may be repeatedly performed until the actual gain is equal to the target gain. Thus, the accuracy of the transmit power calibration can be improved.
For example, assuming a target gain of 25db for the power amplifier by the user, the configured gain of the power amplifier may be set to 25 db. If the data processing terminal derives an actual gain of the power amplifier of 28db, the power amplifier may be considered to have an error, and the actual gain does not satisfy the target gain desired by the user. At this time, the gain adjustment value may be determined to be-3 according to the formula T-25-28. And then, the data processing terminal sends the new gain adjustment parameter-3 to the power amplifier of the terminal to be calibrated, so that the power amplifier adjusts the current gain according to the-3 and determines that the new configuration gain is 25db-3db, namely 22 db. In the case of a configuration gain of 22db, the second signal is reacquired and a new actual gain is determined. And repeating the steps until the actual gain is 25db, and finishing the transmission power calibration process.

In a specific implementation process, before the receiving module 42 receives the second signal that is output by the power amplifier performing power amplification on the first signal under the configured gain, the sending module 41 is further configured to send the first transmission parameter and the second transmission parameter to the baseband chip. Wherein the first transmission parameter can be used to determine the initial power of the initial signal that the baseband chip needs to generate. The second transmission parameter may be sent by the baseband chip to the radio frequency chip of the terminal to be calibrated, and the second transmission parameter may be used to determine the first power of the first signal generated by the radio frequency chip according to the initial signal.
