Background
In order to meet the requirements of users, Radio Frequency Integrated Circuits (RFICs) of the terminal may transmit data to the outside at different output powers; while RFIC has an Automatic Gain Control (AGC) function, different AGC values will cause RFIC to produce different output powers.

Fig. 3 shows a flowchart of a calibration method for output power according to an exemplary embodiment of the present application. In the embodiment of the present application, before calibrating the output power, an initial AGC value, that is, a first AGC value, during output power calibration needs to be obtained through a test first, and the first AGC value may be obtained through a test of a current terminal or may be obtained through a test of other terminals. In this embodiment, a description is given by taking the first AGC value as an example obtained by the current terminal test, that is, how the terminal obtains the first AGC value is mainly described in this embodiment. The method comprises the following steps:
step 301: the terminal acquires the maximum output power.
The terminal supports output power of multiple frequency bands, where the maximum output power is a maximum output power corresponding to the multiple frequency bands, or the maximum output power is a maximum output power corresponding to a target frequency band in the multiple frequency bands. In a possible implementation, the maximum output power is stored in the terminal when the maximum output power is the maximum output power corresponding to the multiple frequency bands; correspondingly, the step of acquiring the maximum output power by the terminal includes: the terminal directly acquires the stored maximum output power.
In another possible implementation manner, the maximum output power is not stored in the terminal, that is, the terminal does not know the maximum output power of itself, and at this time, the terminal needs to obtain the maximum output power by means of the network device; correspondingly, the step of acquiring the maximum output power by the terminal includes: the terminal sends a first acquisition request to the network equipment, wherein the first acquisition request carries the identifier of the terminal and is used for requesting the network equipment to return the maximum output power of the terminal; and the network equipment receives the first acquisition request and sends the maximum output power to the terminal.
It should be noted that different types of terminals correspond to different maximum output powers; correspondingly, the first obtaining request also carries the type of the terminal, and the network device obtains the maximum output power corresponding to the type and sends the maximum output power corresponding to the type to the terminal.
The step of acquiring the maximum output power by the terminal under the condition that the maximum output power is the maximum output power corresponding to a target frequency band in the multiple frequency bands includes: and the terminal determines a target frequency band and acquires the maximum output power corresponding to the target frequency band. The target frequency band is a frequency band to be subjected to output power calibration, and the maximum output power corresponding to the target frequency band is the maximum value of the target frequency band. For example, if the target frequency band is 10-23dBm, the maximum output power Pmax corresponding to the target frequency band is 23 dBm. For example, referring to fig. 4, the maximum output power Pmax of the target frequency band of the terminal is set to 23 dBm.
In this embodiment of the application, the terminal supports the output powers of multiple frequency bands, where the maximum output power is the maximum output power corresponding to the target frequency band in the multiple frequency bands, the terminal may obtain the first AGC value corresponding to each frequency band according to steps 301-305, and then calibrate the output power of the RFIC based on the first AGC value corresponding to each frequency band, thereby implementing the segmented accurate calibration.
Step 302: the terminal acquires the fifth AGC value and the third output power.
The fifth AGC value is an AGC value predicted based on the maximum output power, and the third output power is an output power generated by the RFIC when the RFIC is driven based on the fifth AGC value. In the case where the PA is included in the terminal, the PA is connected in series after the RFIC, and the third output power is a power in which the output power generated by the RFIC is amplified by the PA when the RFIC is driven based on the fifth AGC value.
Different maximum output power corresponds to different fifth AGC values, but the loss of RFICs of different terminals is different, so that the maximum output power and the fifth AGC value do not have a fixed corresponding relation, but the maximum output power is larger, and the fifth AGC value is larger; accordingly, the operator can set the fifth AGC value based on the maximum output power empirically. Correspondingly, the step of acquiring the fifth AGC value by the terminal includes: the terminal displays a configuration interface, the configuration interface displays an input box corresponding to the maximum output power and the fifth AGC value, and an operator can input the fifth AGC value in the input box; the terminal acquires the fifth AGC value input in the input box. For example, if the fifth AGC value is 50, the fifth AGC value n of RFIC is set to 50 according to the maximum output power, with reference to fig. 4.
Step 303: the terminal determines whether the third output power is greater than or equal to a fourth output power, which is an output power obtained by increasing the maximum output power by a unit power value.
If the unit power value is 1dB, the fourth output power P is the third output power +1dB, that is, if n is 50, the actual output power P is calibrated to be greater than or equal to Pmax, and the margin of 1dB is met, that is, if n is 50, the actual output power P is calibrated to be greater than or equal to Pmax + 1; if P is larger than or equal to Pmax +1, executing step 304; in case P < Pmax +1, step 305 is executed.
It should be noted that, in the related art, the margin is often set to 3dB, that is, the condition is determined whether the output power P satisfies P ≧ Pmax + 3; due to the fluctuation of the output power caused by the difference of the terminals, if the judged condition is that whether the output power P meets P ≧ Pmax +3, the actual P may be higher, and there is a risk of burning the PA or RFIC of the terminal in the calibration process. In the embodiment of the application, because only 1dB of margin is set, compared with the scheme in the related art, the power is reduced by 2dB, so that the risk of burning out the PA or the RFIC due to overhigh power is greatly reduced.
Step 304: in case that the third output power is greater than or equal to the fourth output power, the terminal determines the fifth AGC value as the first AGC value.
The first AGC value is an initial AGC value at the time of output power calibration. When the third output power is greater than or equal to the fourth output power, the RFIC generates the third output power that can satisfy the maximum output power requirement of the terminal, that is, the fifth AGC value, when the RFIC is driven based on the fifth AGC value
The fifth AGC value is determined as the first AGC value, i.e. the fifth AGC value is subsequently used to calibrate the output power of the RFIC.
Step 305: and under the condition that the third output power is smaller than the fourth output power, the terminal increases the fifth AGC value to obtain the first AGC value.
When the third output power is lower than the fourth output power, it is described that when the RFIC is driven based on the fifth AGC value, the third output power generated by the RFIC cannot meet the maximum output power requirement of the terminal, that is, the fifth AGC value is set too small, and at this time, the fifth AGC value needs to be increased to obtain the first AGC value.
In a possible implementation manner, the terminal increases the fifth AGC value by a third threshold to obtain a sixth AGC value, determines a fifth output power based on the sixth AGC value, where the fifth output power is an output power generated by the RFIC when the RFIC is driven based on the sixth AGC value, and determines whether the fifth output power is greater than or equal to the fourth output power; determining the sixth AGC value as the first AGC value in case the fifth output power is greater than or equal to the fourth output power; and under the condition that the fifth output power is less than the fourth output power, increasing the sixth AGC value by a third threshold value until a first AGC value of which the corresponding output power is greater than or equal to the fourth output power is obtained.
In a possible implementation manner, the third threshold is set in advance, and the third threshold may be set and changed as needed, and in this embodiment, the third threshold is not specifically limited. For example, the third threshold is 1, i.e., 1 is added to the fifth AGC value to obtain the first AGC value.
In another possible implementation manner, the third threshold may be determined according to a difference between the fourth output power and the third output power; correspondingly, the step of the terminal determining the third threshold includes: the terminal determines a difference between the fourth output power and the third output power, and determines a third threshold value matching the difference. For example, each difference corresponds to a third threshold or a range of differences corresponds to a third threshold; correspondingly, the step of the terminal determining the third threshold matched with the difference value includes: the terminal determines a third threshold corresponding to the difference value from the corresponding relation between the difference value and the third threshold based on the difference value; or the terminal determines a difference range in which the difference value is located, and determines a third threshold corresponding to the difference range from the corresponding relationship between the difference range and the third threshold based on the difference range.
It should be noted that, the above steps 301-305 are a process of obtaining the first AGC value by the terminal test, and each terminal does not need to perform a test once, but only needs to perform a test process once by one terminal, after obtaining the first AGC value, the first AGC value is shared with other terminals, and then the other terminals calibrate their own output power of the RFIC based on the first AGC value. The terminal may send the first AGC value to the network device, and the first AGC value is written into another terminal by the network device, or the network device stores the first AGC value, and obtains the first AGC value from the network device when the other terminal calibrates the output power of the RFIC.
In the embodiment of the present application, when determining the first AGC value, it is determined whether the third output power is greater than or equal to the fourth output power, and the fourth output power is an output power obtained by increasing the maximum output power by a unit power value, and since the unit power value is 1dB, only setting a margin of 1dB is achieved, and compared with 3dB set by a scheme in the related art, the margin is reduced by 2dB, so that a risk that the PA is burned or the RFIC is burned due to over-high power is greatly reduced.
Fig. 5 shows a flowchart of a calibration method for output power according to an exemplary embodiment of the present application. In the embodiment of the present application, an example in which the terminal calibrates the output power of the RFIC based on the first AGC value is described. The method comprises the following steps:
step 501: the terminal acquires the maximum output power.
The step of acquiring the maximum output power by the terminal is the same as step 301, and is not described herein again.
Step 502: the terminal acquires a first AGC value, wherein the first AGC value is an initial AGC value during output power verification.
The first AGC value is determined by the current terminal or other terminals during the testing phase. If the first AGC value is determined by the current terminal in the test stage, the first AGC value is stored in the terminal after being determined; the stored first AGC value is directly obtained in this step. If the first AGC value is determined by other terminals in the test stage, the other terminals send the first AGC value to the network equipment; accordingly, the current terminal obtains the first AGC value from the network device.
In one possible implementation, different terminal types correspond to different first AGC values; correspondingly, the step of acquiring the first AGC value by the terminal includes: the terminal determines the type of the terminal and acquires a first AGC value matched with the type. After testing the first AGC value corresponding to each type, the multiple types of other terminals send the types of the other terminals and the corresponding first AGC values to the network device, that is, the network device stores the corresponding relationship between the types and the first AGC values. Correspondingly, the step that the terminal determines the type of the terminal and obtains the first AGC value matched with the type comprises the following steps: determining the type of the terminal, and sending a second acquisition request to the network equipment, wherein the second acquisition request carries the type of the terminal, and the second acquisition request is used for requesting to acquire a first AGC value matched with the type; the network equipment receives the second acquisition request, acquires a first AGC value corresponding to the type from the corresponding relation between the type and the first AGC value based on the type, and sends the first AGC value to the terminal, and the terminal receives the first AGC value sent by the network equipment.
In the embodiment of the application, different terminal types correspond to different first AGC values, so that the accuracy of the obtained first AGC value can be improved, the risk that PA or RFIC is burnt due to the fact that the actual output power is too high due to the fact that the first AGC value is too large is reduced, and the problem that the calibration efficiency is low due to the fact that the first AGC value is too small and the second AGC value meeting the conditions can be found by adjusting the first AGC value for multiple times is solved.
In another possible implementation, different maximum output powers correspond to different first AGC values; correspondingly, the step of acquiring the first AGC value by the terminal includes: and the terminal acquires a first AGC value corresponding to the maximum output power. The network equipment stores the corresponding relation between the maximum output power and a first AGC value; correspondingly, the step of acquiring the first AGC value corresponding to the maximum output power by the terminal includes: the terminal sends a third acquisition request to the network equipment, wherein the third acquisition request carries the maximum output power and is used for requesting the network equipment to acquire a first AGC value corresponding to the maximum output power; the network device receives the third obtaining request, obtains the first AGC value corresponding to the maximum output power from the corresponding relation between the maximum output power and the first AGC value, and sends the first AGC value to the terminal, and the terminal receives the first AGC value sent by the network device.
In the embodiment of the application, different maximum output powers correspond to different first AGC values, so that the corresponding first AGC value is found based on the maximum output power, and the accuracy of the determined first AGC value is improved.
Step 503: the terminal checks the first AGC value based on the first AGC value and the maximum output power, and the checking is used for checking whether the first AGC value meets the maximum power requirement of the terminal.
This step can be realized by the following steps (1) to (3), including:
(1) the terminal determines a first output power based on the first AGC value.
The first output power is an output power generated by the RFIC of the terminal when the RFIC is driven based on the first AGC value. When the PA is included in the terminal and is connected in series with the RFIC, the first output power is a power obtained by amplifying the output power generated by the RFIC by the PA when the RFIC is driven based on the first AGC value.
(2) And the terminal determines that the first AGC value is checked to be passed under the condition that the first output power is greater than or equal to the second output power.
The second output power is the sum of the maximum output power and a first threshold. When the first output power is greater than or equal to the second output power, it is explained that the RFIC of the terminal is driven based on the first AGC value, the output power generated by the RFIC can satisfy the maximum power requirement of the terminal.
The first threshold value can be set and changed as required; in the embodiment of the present application, the first threshold is not particularly limited; for example, the first threshold value is 0 or 1, etc.
(3) And in the case that the first output power is smaller than the second output power, the terminal determines that the first AGC value is not checked.
When the first output power is lower than the second output power, it is described that when the RFIC of the terminal is driven based on the first AGC value, the output power generated by the RFIC cannot meet the maximum power requirement of the terminal, that is, the maximum output power of the terminal is insufficient, and the RFIC does not meet the normative requirement.
It should be noted that, in the case that the first AGC value is verified, step 504 is executed; in the event that the first AGC value is not validated, step 505 is performed.
Step 504: in case that the first AGC value is verified, the terminal determines the first AGC value as the second AGC value.
When the first AGC value is verified, it is explained that when the RFIC of the terminal is driven based on the first AGC value, the output power generated by the RFIC can satisfy the maximum power requirement of the terminal, and therefore, the first AGC value can be used as the initial AGC value in power calibration.
Step 505: and under the condition that the first AGC value is not checked, the terminal increases the first AGC value to obtain a second AGC value.
When the first output power is lower than the second output power, it is described that when the RFIC of the terminal is driven based on the first AGC value, the output power generated by the RFIC cannot meet the maximum power requirement of the terminal, that is, the maximum output power of the terminal is insufficient, which does not meet the regulatory requirement. Although there is no fixed correspondence between the AGC value and the output power, it is shown that the larger the AGC value is, the larger the output power is; therefore, in order to meet the maximum power requirement of the terminal, the first AGC value needs to be increased to find an AGC value meeting the maximum power requirement of the terminal.
In a possible implementation manner, the step of increasing the first AGC value by the terminal and obtaining the second AGC value may be implemented by the following steps (1) to (4), including:
(1) and the terminal increases the first AGC value by a second threshold value to obtain a fourth AGC value.
In a possible implementation manner, the second threshold is set in advance, and the second threshold may be set and changed as needed, and in this embodiment, the second threshold is not specifically limited. For example, the third threshold is 1, i.e., 1 is added to the first AGC value to obtain the fourth AGC value.
In another possible implementation manner, the second threshold may be determined according to a difference between the second output power and the first output power; correspondingly, the step of the terminal determining the second threshold includes: the terminal determines a difference between the second output power and the first output power, and determines a second threshold value matching the difference. For example, each difference corresponds to a second threshold or a range of differences corresponds to a second threshold; correspondingly, the step of the terminal determining the second threshold matched with the difference value comprises the following steps: the terminal determines a second threshold corresponding to the difference value from the corresponding relation between the difference value and the second threshold based on the difference value; or the terminal determines a difference range in which the difference value is located, and determines a second threshold corresponding to the difference range from the corresponding relationship between the difference range and the second threshold based on the difference range.
(2) And the terminal checks the fourth AGC value based on the fourth AGC value and the maximum output power, wherein the check is used for checking whether the fourth AGC value meets the maximum power requirement of the terminal.
The process of the terminal verifying the fourth AGC value based on the fourth AGC value and the maximum output power is similar to the process of the terminal verifying the first AGC value based on the first AGC value and the maximum output power, and is not repeated here.
(3) In case that the verification passes for the fourth AGC value, the terminal determines the fourth AGC value as the second AGC value.
(4) And in the case that the fourth AGC value is not verified, the terminal increases the fourth AGC value by a second threshold value until a second AGC value which is verified to be passed is obtained.
Step 506: the terminal calibrates an output power of the terminal based on the second AGC value.
This step can be realized by the following steps (1) to (3), including:
(1) the terminal determines a plurality of third AGC values based on the second AGC value.
And the terminal performs multiple degressive actions on the second AGC value based on the preset adjustment amplitude to obtain multiple third AGC values. For example, if the preset adjustment amplitude is 1, the terminal subtracts 1 from the second AGC value to obtain a third AGC value, subtracts 2 from the second AGC value to obtain a third AGC value again, subtracts 3 from the second AGC value to obtain a third AGC value again, and so on, to obtain a plurality of third AGC values. For example, the second AGC value is 50, and the plurality of third AGC values are 49, 48, 47, … … 1, respectively.
(2) The terminal determines a plurality of sixth output powers based on the plurality of third AGC values.
Each sixth output power corresponds to a third AGC value, and the sixth output power is an output power generated by the RFIC when the RFIC is driven based on the third AGC value. In a case where the terminal includes a PA connected in series after the RFIC, the sixth output power is a power at which the output power generated by the RFIC is amplified by the PA when the RFIC is driven based on the third AGC value.
The step of determining the plurality of sixth output powers by the terminal based on the plurality of third AGC values is similar to the step of determining the first output power by the terminal based on the first AGC value, and is not repeated herein.
(3) And the terminal stores the corresponding relation between the plurality of third AGC values and the plurality of sixth output powers.
And the terminal stores the corresponding relation between the plurality of third AGC values and the plurality of sixth output powers so as to transmit data outwards based on the corresponding relation. For example, when the terminal needs to transmit data to the outside based on a certain sixth output power, the terminal acquires a third AGC value corresponding to the sixth output power from a corresponding relationship between the third AGC value and the sixth output power based on the sixth output power, drives the RFIC to generate the sixth output power based on the third AGC value, and transmits data to the outside based on the sixth output power.
The terminal determines a seventh output power based on the second AGC value, and the seventh output power is an output power generated by the RFIC when the RFIC is driven based on the second AGC value. In a case where the terminal includes a PA connected in series after the RFIC, the seventh output power is a power at which the output power generated by the RFIC is amplified by the PA when the RFIC is driven based on the second AGC value. The terminal also stores the second AGC value and the seventh output power in the correspondence.
For example, with continued reference to fig. 4, the terminal sequentially decreases from the second AGC value by 1 to 0, records the corresponding output power, writes the obtained AGC value and its corresponding output power into the terminal, and subsequently uses the first AGC value to calibrate other terminals of the same model.
It should be noted that, after the terminal determines the second AGC value, the terminal may also share the second AGC value with other terminals, and then the other terminals calibrate their RFICs output power based on the second AGC value. The terminal may send the second AGC value to the network device, and the second AGC value is written into another terminal by the network device, or the network device stores the second AGC value, and obtains the second AGC value from the network device when the other terminal calibrates the output power of the RFIC. The other terminals may be terminals of the same type as the current terminal, and the same type refers to terminals of the same model.
In the embodiment of the application, after the initial AGC value for output power calibration is obtained, that is, the first AGC value is obtained, the output power is not directly calibrated based on the initial AGC value, but a second AGC value meeting the maximum power requirement of the terminal is determined based on the maximum output power of the terminal and the first AGC value, and since the second AGC value can meet the maximum power requirement of the terminal, the accuracy of calibrating the output power of the RFIC based on the second AGC value is higher, that is, the accuracy of output power calibration is improved.
