Detailed ways

The embodiment of the present application provides a power calibration method for maximum power fluctuation, a terminal device and a storage medium, which are used to improve the calibration efficiency by scanning from the minimum AGC value to the AGC value that meets the maximum power requirement, and can Meet the compliance indicators of the maximum power of different terminal equipment.

In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the application will be described below in conjunction with the drawings in the embodiment of the application. Obviously, the described embodiment is only a part of the application Examples, but not all examples. Based on the embodiments in this application, all should belong to the protection scope of this application.

In the prior art, set the maximum power upper limit Pmax of a certain calibration frequency band of the specified terminal equipment, such as Pmax=23dBm; set the maximum scan AGC initial value n of the radio frequency chip (Radio Frequency Integrated Circuits, RFIC) according to the maximum power upper limit . For different AGC values, corresponding to different calibration output power. Since the loss of the radio frequency path of different terminals is not the same, there is no fixed correspondence between the AGC value and the final output power, but it shows a linear relationship between the larger the AGC value and the larger the final output power. Generally, the initial value n can be set = about 50;

Set n=50 to calibrate and test whether the actual output power P is greater than or equal to Pmax, and meet the 3dB margin, that is, whether P≥Pmax+3 is satisfied; after satisfying, record the n value at this time (denoted as n0); if If the above conditions are met, use the AGC value at this time, that is, the value of n0 to start the calibration process, scan from n0 to 0 in a decreasing manner, and the step size is 1; and record the specific output corresponding to n=n0 to n=0 Power value, save the result to the terminal device. Use this n0 value to calibrate other end-equipment individuals of the same model.

The process of finding this n0 value is cumbersome and affects efficiency; this n0 value found by one or some individuals, in the process of mass production, the reserved 3dB margin cannot be used for power fluctuations and differences caused by individual differences. Ensure that all terminals of the same type meet the calibration requirements, or this n0 value is too high for some individuals, and there is a risk of burning the front-end power amplifier (Power Amplifier, PA); or this n0 value is too high for some individuals If it is too low, the maximum output power of the terminal is insufficient, which does not meet the compliance index requirements.

By scanning from the minimum AGC value to the AGC value that meets the maximum power requirement, the calibration efficiency is improved, and the compliance index of the maximum power of different terminal equipment can be met. It overcomes the steps that the original algorithm needs to find the n0 value, which improves the calibration efficiency; overcomes the problem that the original algorithm’s n0 value is too large for some motherboards and may burn the power amplifier (Power Amplifier, PA); overcomes the original algorithm’s n0 The value is too small for some motherboards, resulting in too small terminal output power, resulting in the problem that the maximum power compliance index cannot be met. That is to say, this application innovatively proposes a power calibration scheme that can cover the maximum power difference of different main boards, which is different from the current original calibration method, by scanning from the minimum AGC value to the AGC value that meets the maximum power requirement, to improve It improves the efficiency and eliminates the two risks of the previous algorithm.

As shown in Figure 4, it is a schematic diagram of another embodiment of the power calibration method for maximum power fluctuation in the embodiment of the present application, which may include:

401. Set the maximum power upper limit Pmax of the first calibration frequency band of the specified terminal device, set the minimum power lower limit Pmin of the first calibration frequency band, and determine the first scan initial value n1 of the automatic gain control AGC of the radio frequency transceiver chip RFIC , the first value n1 is greater than 0 and less than a preset maximum scanning initial value.

Optionally, the determination of the first scanning initial value n1 of the automatic gain control AGC of the radio frequency transceiver chip RFIC may include:

Setting the second scanning initial value n2 of the automatic gain control AGC of the radio frequency transceiver chip RFIC;

Test whether n takes the current calibration power of the second scan initial value n2, greater than or equal to the difference between the Pmin and the second offset value, and less than or equal to the difference between the Pmin and the third offset value, the first an offset value smaller than the second offset value, the second offset value smaller than the third offset value;

In the case where the current calibration power of the second scanning initial value n2 of the n is greater than or equal to the difference between the Pmin and the second offset value, and is less than or equal to the difference between the Pmin and the third offset value, the The second scanning initial value n2 is used as the first scanning initial value n1 of the automatic gain control AGC of the radio frequency transceiver chip RFIC;

When the current calibration power of the second scan initial value n2 for the n is not satisfied, it is greater than or equal to the difference between the Pmin and the second offset value, and is less than or equal to the difference between the Pmin and the third offset value Next, the n is n2+1, and it is tested whether the current calibration power of n is n2+1 is greater than or equal to the difference between the Pmin and the second offset value, and is less than or equal to the difference between the Pmin and the third offset value;

In the case that the current calibration power of n2+1 is greater than or equal to the difference between the Pmin and the second offset value, and less than or equal to the difference between the Pmin and the third offset value, the n2+1 is used as the The first scanning initial value n1 of the automatic gain control AGC of the radio frequency transceiver chip RFIC.

Exemplarily, the maximum power upper limit of a certain calibration frequency band of the specified terminal equipment is set as Pmax, the minimum power lower limit Pmin of the first calibration frequency band is set, and the radio frequency transceiver chip (Radio Frequency Integrated Circuits, RFIC) is also set. The automatic gain control (Auto Gain Control, AGC) scans the initial value n2, where n2 is 20, for example, the second offset value is 7, and the third offset value is 6. Test whether the current calibration power P corresponding to n=20 satisfies Pmin-7≤P≤Pmin-6.

If the current calibration power P corresponding to n=20 satisfies Pmin-7≤P≤Pmin-6, then n=20 is taken as the initial value n1 of the first scan. If the current calibration power P corresponding to n=20 does not satisfy Pmin-7≤P≤Pmin-6, then take n=n+1=20+1=21, and test whether the current calibration power P corresponding to n=21 satisfies Pmin-7≤P≤Pmin-6.

If the current calibration power P corresponding to n=21 satisfies Pmin-7≤P≤Pmin-6, then n=21 is taken as the initial value n1 of the first scan. If the current calibration power P corresponding to n=21 does not satisfy Pmin-7≤P≤Pmin-6, then take n=n+1=21+1=22, and test whether the current calibration power P corresponding to n=22 satisfies Pmin-7≤P≤Pmin-6, and so on, which will not be repeated here.

It can be understood that the embodiment of the present application can improve the initial AGC setting value, that is, it is not necessary to start the calibration scan from the minimum value of 0, and only need to meet the minimum AGC value to meet the requirements of the calibration minimum power. If it is too high, there will be problems of burning PA or too small compliance index, so the range that can be set is more flexible and the range is relatively wide. You can set a margin of about 6dB on the basis of the set minimum calibration power. This margin is enough to cover power fluctuations between different terminal devices.

It should be noted that the first offset value, the second offset value and the third offset value in the present application can be adjusted according to actual conditions, and are not specifically limited in the present application.

Optionally, the first offset value is 0, and the test whether the current calibration power P whose n is 0 is greater than or equal to the sum of the Pmax and the first offset value; When P is greater than or equal to the sum of the Pmax and the first offset value, record the power value corresponding to n being 0 and write it into the designated terminal device; when the current calibration power P of n is 0 is less than the set In the case of the sum of the Pmax and the first offset value, n is n+1, and whether the current calibration power P of n+1 is greater than or equal to the sum of the Pmax and the offset value; in the n When the current calibration power P of n+1 is greater than or equal to the sum of the Pmax and the offset value, record the power value corresponding to each n from 0 to n+1 and write it into the designated terminal device, The following 402-405 steps can be included as follows:

402. Test whether n takes the initial value n1 of the first scan to see if the current calibration power P is greater than or equal to the Pmax.

For example, n1 is 21. Exemplarily, it is tested whether the current calibration power P corresponding to n=n1=21 is greater than or equal to Pmax. That is, it can be judged whether the current calibration power corresponding to n=21 is P≥Pmax or P<Pmax.

403. In the case that n takes the initial value n1 of the first scan and the current calibration power P is greater than or equal to the Pmax, record n takes the power value corresponding to the initial value n1 of the first scan and writes it into the specified Terminal Equipment.

Exemplarily, if the current calibration power P≥Pmax corresponding to n=21, record the power value corresponding to n=21 at this time and write it into the specified terminal device.

Optionally, the method may further include: in the case that the current calibration power P of the n being n1 is greater than or equal to the Pmax, using the current calibration power P corresponding to the n being n1 as the specified terminal device Maximum power.

404. In the case that the current calibration power P where n is the initial value n1 of the first scan is less than the Pmax, n is n+1, and it is tested whether the current calibration power P where n is n+1 is greater than or equal to the Pmax.

Exemplarily, if the current calibration power P corresponding to n=21<Pmax, then n=n+1=21+1=22, it is tested whether the current calibration power P corresponding to n=22 is greater than or equal to Pmax. That is, it can be judged whether the current calibration power corresponding to n=22 is P≥Pmax or P<Pmax.

405. In the case that n is n+1 and the current calibration power P is greater than or equal to the Pmax, record the power value corresponding to each n from n1 to n+1 and write it into the specified terminal device.

Exemplarily, if the current calibration power P≥Pmax corresponding to n=22, record the power values corresponding to n=21 and n=22 respectively and write them into the specified terminal device.

Optionally, the method may further include: in the case that the current calibration power P of the n being n+1 is greater than or equal to the Pmax, using the current calibration power P corresponding to the n being n+1 as the Specifies the maximum power of the end device.

406. Use the first scan initial value n1 as the initial scan minimum value, and calibrate the power of other terminal devices of the same type.

Exemplarily, the first scan initial value n1 may be used as the initial scan minimum value to calibrate the power of other terminal devices of the same type. Other terminal devices of the same type do not need to determine the initial scan minimum value, which improves calibration efficiency.

Optionally, step 406 is an optional step.

Exemplarily, as shown in FIG. 5 , it is a schematic flowchart of a power calibration method for maximum power fluctuation in an embodiment of the present application. Setting the maximum power upper limit Pmax of a certain calibration frequency band of the specified terminal device; setting the minimum power lower limit Pmin of the first calibration frequency band. It can be understood that the embodiment of the present application can improve the initial AGC setting value, that is, it is not necessary to start the calibration scan from the minimum value of 0, and only need to meet the minimum AGC value to meet the requirements of the calibration minimum power. If it is too high, there will be problems of burning PA or too small compliance index, so the range that can be set is more flexible and the range is relatively wide. You can set a margin of about 6dB on the basis of the set minimum calibration power. This margin is enough to cover power fluctuations between different terminal devices. Starting from the AGC set value, the step size is step=1, increasing the AGC value n in turn, and recording the calibration power value corresponding to each n value; when the power value corresponding to the n value is greater than or equal to Pmax, the calibration stops. Record the AGC value from the set value to the maximum corresponding power calibration value, and the final result is written into the terminal device.

In this embodiment of the present application, the maximum power upper limit Pmax of the first calibration frequency band of the specified terminal equipment is set, the minimum power lower limit Pmin of the first calibration frequency band is set, and the automatic gain control AGC of the radio frequency transceiver chip RFIC is determined. A scanning initial value n1, the first value n1 is greater than 0 and less than the preset maximum scanning initial value; test whether n takes the current calibration power P of the first scanning initial value n1 greater than or equal to the Pmax; In the case that the current calibration power P of the first scan initial value n1 is greater than or equal to the Pmax, record n takes the power value corresponding to the first scan initial value n1 and writes it into the designated terminal device; In the case where the current calibration power P of the first scan initial value n1 is less than the Pmax, n is n+1, and the current calibration power P of n is n+1 is tested to be greater than or equal to the Pmax; In the case that the current calibration power P of n+1 is greater than or equal to the Pmax, record the power value corresponding to each n from n1 to n+1 and write it into the designated terminal device. The first scanning initial value n1 is used as the initial scanning minimum value to calibrate the power of other terminal devices of the same type. By scanning from the set AGC value to the AGC value that meets the maximum power requirement, the calibration efficiency is improved, and the compliance index of the maximum power of different terminal equipment can be met. It overcomes the steps that the original algorithm needs to find the n0 value, which improves the calibration efficiency; overcomes the problem that the original algorithm’s n0 value is too large for some motherboards and may burn the power amplifier (Power Amplifier, PA); overcomes the original algorithm’s n0 The value is too small for some motherboards, resulting in too small terminal output power, resulting in the problem that the maximum power compliance index cannot be met. That is, because the minimum power requirements in actual scenarios are not as strict as the maximum power, and there will be no problems of PA burnout or compliance with low power, so this application innovatively proposes a method that can cover the maximum power of different motherboards. The power calibration scheme of power difference is different from the current original calibration method. By scanning from the set AGC value to the AGC value that meets the maximum power requirement, the efficiency is improved and the two risks of the previous algorithm are eliminated.
