[0053] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the disclosed embodiments. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present disclosure. It should be noted that, in the absence of conflict, the embodiments in the present disclosure and the features in the embodiments can be arbitrarily combined with each other.

[0054] For easier understanding, the following is a brief explanation of standard NTN terminals and non-standard NTN terminals:

[0055] Standard NTN terminals communicate with satellites defined by the 3GPP (3rd Generation Partnership Project). These satellites can be commercial mobile communications satellites with high antenna gain. Non-standard NTN terminals, on the other hand, communicate with satellites with capabilities that differ from those defined by the 3GPP (3rd Generation Partnership Project), such as those that have been in orbit for many years but have not yet reached retirement age. The transmit and receive signal power of these satellites meets the uplink and downlink signal power requirements of the satellite in question, but differs from the values ​​specified in the 3GPP standard NTN communication protocol.

[0056] As shown in the block diagram of the standard NTN terminal in Figure 1, the uplink line of the standard NTN terminal includes an NTN baseband circuit 11, an NTN RF transceiver chip 12, a transmit power amplifier 13, and an uplink transmit antenna 14. The downlink line of the standard NTN terminal includes a downlink receive antenna 15, a first receive filter 16, a low-noise amplifier 17, a second receive filter 18, the NTN baseband circuit 11, and the NTN RF transceiver chip 12.

[0057] In the uplink, the NTN baseband circuit 11 generates a digital signal based on information and converts it into an IQ (In-Phase Quadrature) signal using a preset coding method. The IQ signal is then sent to the NTN RF transceiver chip 12. The NTN RF transceiver chip 12 converts the IQ signal into an RF signal, which is then transmitted to a transmit power amplifier 13. It should be noted that the RF signal has a relatively low power. If the RF signal is transmitted to the uplink transmit antenna 14 at the current power, the RF signal will be severely attenuated when the satellite receives it, which can easily cause the satellite to fail to successfully identify the RF signal. Therefore, a transmit power amplifier 13 is provided on the transmit circuit to amplify the power of the RF signal so that the satellite can successfully identify the RF signal. The uplink transmit antenna 14 is used by the terminal to transmit information (such as the information contained in the RF signal) to the satellite.

[0058] In the downlink, the downlink receiving antenna 15 is used to transmit information (such as information contained in the RF signal) from the satellite to the base station (terminal). It should be noted that the signal transmitted by the satellite to the base station includes both useful signals and noise signals (such as cosmic background radiation). To obtain a clean useful signal, a first receive filter 16 can be provided in the downlink. The first receive filter 16 is used to initially filter out interference signals to obtain the useful signal. The useful signal attenuates during its journey from the satellite to the terminal. Therefore, when the NTN RF transceiver chip 12 receives the useful signal, it may not be able to identify the information contained in the useful signal. Therefore, a low-noise amplifier 17 can be provided in the downlink. The low-noise amplifier 17 is used to amplify the power of the useful signal. Because the first receive filter 16 cannot completely filter out the noise signal, the power of the noise signal in the signal after passing through the low-noise amplifier 17 is also increased. To obtain a cleaner useful signal, a second receive filter 18 can be provided in the downlink to further filter the signal. The NTN RF receiver chip 12 is used to identify the useful signal, convert the useful signal from the RF signal into a digital signal (such as an IQ signal), and transmit this digital signal to the NTN baseband circuit 11. The NTN baseband circuit 11 is used to receive digital signals and parse the digital signals using a preset coding method to obtain information sent by the satellite.

[0059] FIG2 shows a block diagram of a Beidou terminal, which is a specific embodiment of a non-standard NTN terminal. The uplink link of the Beidou terminal includes a Beidou baseband circuit 21, a Beidou RF transceiver chip 22, a first low-noise amplifier 23, a transmit power amplifier 24, a transmit isolator 25, and an uplink transmit antenna 26. The downlink link of the Beidou terminal includes a downlink receive antenna 27, a first receive filter 28, a second low-noise amplifier 29, a second receive filter 30, a third low-noise amplifier 31, a third receive filter 32, an NTN baseband circuit 21, and an NTN RF transceiver chip 22. The functions of the uplink and downlink components in the Beidou terminal can be referenced to those of the uplink and downlink components in a standard NTN terminal and will not be further described here.

[0060] It should be noted that the transmission power required by Beidou terminals is relatively high. For example, the transmission power of a standard NTN terminal is 2W, while that of a Beidou terminal is 10W. Therefore, if an abnormality occurs in the uplink transmission antenna 26 (for example, if the uplink transmission antenna 26 is disconnected or in poor contact), the RF signal will be returned to the transmission power amplifier 24. The high-power RF signal is likely to damage the transmission power amplifier or other components (such as the first low-noise amplifier 23 and the Beidou RF transceiver chip 22). Therefore, a transmission isolator 25 is provided in the uplink circuit of the Beidou terminal to prevent component damage caused by the return of unsuccessfully transmitted RF signals. The transmission isolator 25 is used to allow unidirectional transmission of RF signals. In addition, the reason for providing two sets of receiving filters and low-noise amplifiers in the downlink is that the power of the downlink signal sent by the satellite to the terminal is relatively low, and the effect of amplifying it only once cannot meet the power requirement. Therefore, providing two sets of receiving filters and low-noise amplifiers in the downlink ensures that the power of the RF signal meets the power requirement, thereby ensuring that the Beidou RF transceiver chip 22 can successfully identify the RF signal and then obtain the information contained in the RF signal.

[0061] Standard NTN terminals and non-standard NTN terminals differ significantly in their system architectures. For example, each utilizes dedicated baseband circuitry and RF transceiver chips; each employs different communication protocols; and, due to differing transmit power requirements, utilizes different uplink components and power ranges. Their downlinks also require different designs due to varying signal strengths to be demodulated. To enable terminal devices to transmit signals that conform to both standard NTN uplink power and non-standard NTN uplink power, as shown in Figure 3, the present disclosure discloses a RF terminal compatible with both standard and non-standard NTN terminals. As shown in Figure 3, the RF terminal includes an NTN baseband circuit 33, an NTN RF transceiver chip 34, a first RF switch 35, a standard NTN power amplifier branch 36, a non-standard NTN power amplifier branch 37, a second RF switch 38, and an output power test endpoint 39. The first RF switch 35 can be a single-pole double-throw (SPDT) switch, comprising two fixed terminals (contact A1 and contact B1) and a movable terminal. When the movable terminal is connected to contact A1, the standard NTN power amplifier branch 36 is turned on; conversely, when the movable terminal is connected to contact B1, the non-standard NTN power amplifier branch is turned on. Accordingly, in one example, the second RF switch 38 can also be a SPDT switch, comprising two fixed terminals (contact A2 and contact B2) and a movable terminal. When the movable terminal is connected to contact A2, the standard NTN power amplifier branch 36 is turned on; conversely, when the movable terminal is connected to contact B2, the non-standard NTN power amplifier branch 37 is turned on. It should be noted that when the second RF switch 38 is a SPDT switch, the fixed terminal selected by the movable terminal of the second RF switch 38 should be consistent with the fixed terminal selected by the movable terminal of the first RF switch 35, thereby ensuring that a power amplifier branch can be properly turned on. In another example, the second RF switch 38 may also be a common switch. In this case, the first RF switch 35 may directly determine the branch to be turned on.

[0062] The standard NTN power amplification branch 36 includes a transmit power amplifier 361 that meets the standard NTN uplink power requirements (hereinafter referred to as the standard NTN transmit power amplifier 361). The non-standard NTN power amplification branch 37 includes a low-noise amplifier 371, a transmit power amplifier 372 that meets the non-standard NTN uplink power requirements (hereinafter referred to as the non-standard NTN transmit power amplifier 372), and a transmit isolator 373. Including the transmit isolator 373 in the non-standard NTN power amplification branch 37 is a more optimal design solution for protecting components. Furthermore, when the amplification factor of the non-standard NTN transmit power amplifier is sufficient, the low-noise amplifier 371 in the non-standard NTN power amplification branch 37 can be removed. Therefore, the low-noise amplifier 371 and transmit isolator 373 (represented by dashed lines in the figure) can be removed from the non-standard NTN power amplification branch 37, leaving only the non-standard NTN transmit power amplifier 372. The functions of the components in standard NTN power amplifier branch 36 and non-standard NTN power amplifier branch 37 can be referenced to the functions of the corresponding components in Figures 1 and 2 above, and will not be further described here. Output power test endpoint 39 is used to obtain the output power of the transmitted signal passing through standard NTN power amplifier branch 36 or non-standard NTN power amplifier branch 37.

[0063] However, there is currently no method for power calibration of radio frequency terminals compatible with both standard and non-standard NTN terminals. In practice, these terminals can suffer from inaccurate input or output power, which can easily cause problems with transmitted signals, leading to satellites being unable to successfully interpret the transmitted signals and causing communication failures between the terminal and the satellite.

[0064] To address the aforementioned issues, the present disclosure provides a power calibration method. This method can determine an expected gain difference, determine an actual gain difference based on the expected gain difference and a first output power, determine a second output power based on the actual gain difference and the first output power, and calibrate the power of a transmitted signal in a non-standard NTN power amplifier branch based on the first output power and the second output power. The present disclosure can implement power calibration for both standard and non-standard NTN power amplifier branches by using the expected gain difference and the actual gain difference between the two branches. This ensures accurate input and output power for radio frequency terminals compatible with both standard and non-standard NTN terminals, thereby ensuring that satellites can successfully resolve transmitted signals and facilitate smooth communication between the terminal and the satellite.

[0065] The exemplary embodiments of the present disclosure provide a power calibration method that can be applied to electronic devices, specifically smart devices such as mobile phones, tablet computers, laptops, intelligent robots, vehicle computers, and smart wearable devices. Furthermore, the electronic devices are equipped with various hardware resources and energy storage devices that provide power to these hardware resources.

[0066] As shown in FIG4 , the power calibration method shown in this embodiment includes:

[0067] S401: Determine an expected gain difference.

[0068] S402: Determine an actual gain difference based on the expected gain difference and the first output power.

[0069] S403: Determine a second output power based on the actual gain difference and the first output power.

[0070] S404: Calibrate the input power of the transmission signal in the non-standard NTN power amplification branch based on the first output power and the second output power.

[0071] It should be noted that before performing step S401, power calibration of the standard NTN power amplifier branch must be completed. That is, power calibration of the standard NTN power amplifier branch must be completed in advance. The specific method for power calibration of the standard NTN power amplifier branch can refer to the existing power calibration scheme for a single power amplifier branch and will not be described in detail here. After the power calibration of the standard NTN power amplifier branch is completed, the second configuration information of the branch can be determined, wherein the second configuration information is used to characterize the correlation between the input power (that is, the output power of the transmitted signal after passing through the NTN RF transceiver) and the output power (the output power of the transmitted signal after passing through the standard NTN power amplifier branch) of the transmitted signal in the standard NTN power amplifier branch. In one example, the above correlation relationship can be a correspondence between the input power and output power of the transmitted signal, for example, the input power A3 of the transmitted signal corresponds to the output power B3, and the input power A4 of the transmitted signal corresponds to the output power B4. In another example, the above-mentioned correlation relationship can also be a functional relationship between the input power and output power of the transmitted signal. For example, the functional relationship is a=2b+1, where a represents the output power and b represents the input power. When the input power is 1dBm, the output power can be obtained as 3dBm.

[0072] In one example, the input power can be controlled using a power control parameter X. Specifically, a first command can be written to the NTN RF transceiver. For example, if X = 1, the NTN RF transceiver will output a transmit signal with the corresponding power based on the first command. That is, the power control parameter X is associated with the input power. This association is similar to the association between input power and output power described above and can be a correspondence or a function. For example, X = 1 corresponds to an input power of 10 dBm; X = 2 corresponds to an input power of 11 dBm, and so on. Accordingly, in this example, the second configuration information can be used to characterize the association between the power control parameter and input power, as well as the association between input power and output power. In applications, when the output power of a transmitted signal in a standard NTN power amplifier branch is known, the input power and power control parameters corresponding to that output power can be directly obtained based on the second configuration information. Alternatively, when the input power of a transmitted signal is known, the output power and power control parameters corresponding to that input power can be directly obtained based on the second configuration information. In this way, power calibration of the standard NTN power amplifier branch can be achieved based on the second configuration information.

[0073] In step S401, in one example, the expected gain difference may refer to the absolute value of the difference between a first expected gain value and a second expected gain value, where the first expected gain value is the expected gain value of the non-standard NTN power amplifier branch and the second expected gain value is the expected gain value of the standard NTN power amplifier branch. For example, if the first expected gain value is 25 dB and the second expected gain value is 42 dB, the expected gain difference is 17 dB.

[0074] The first expected gain value is determined by the branch gain value and path loss value of the non-standard NTN power amplifier branch. Correspondingly, the second expected gain value is determined by the branch gain value and path loss value of the standard NTN power amplifier branch. Specifically, the expected gain value may be the sum of the branch gain value and the path loss value. In one example, the branch gain value may refer to the gain value of the power amplifier, and the branch gain value is calculated as follows: Wherein, Gain represents the branch gain value, and lg represents the logarithm with base 10. When the output value is greater than the input value, the branch gain value is characterized as a positive gain; conversely, when the output value of the branch is less than the input value, the branch gain value is characterized as a negative gain. It should be noted that when the branch gain value is characterized as a negative gain, it can be represented as any value in the open interval (-∞, 0); when the branch gain value is characterized as a positive gain, it can be represented as any value in the interval (0, +∞). For example, if the input value of a branch is 0dBm and the output value is 10dBm, the gain value of the branch is 10dB; for another example, if the input value of another branch is 10dBm and the output value is 0dBm, the gain value of the branch is -10dB (estimated value). In another example, a standard NTN power amplifier branch is provided with a standard NTN transmit power amplifier, while a non-standard NTN power amplifier branch is provided with a non-standard NTN transmit power amplifier. Therefore, the branch gain value can be determined by the amplification factors of the amplifiers in the two branches under non-saturation conditions (ideal conditions). For example, if the amplification factor of the non-standard NTN transmit power amplifier in the non-standard NTN power amplifier branch is 10, the branch gain value of the non-standard NTN power amplifier branch can be determined to be 10dB. Similarly, if the amplification factor of the standard NTN transmit power amplifier in the standard NTN power amplifier branch is 0.1, the branch gain value of the standard NTN power amplifier branch can be determined to be -10dB (estimated value). Path loss, also known as propagation loss, refers to the amount of power loss introduced by the propagation environment between the NTN RF transceiver chip and the output power test endpoint. For the same transmission and reception distance, the path loss value is the same.

[0075] In one example, a first expected gain value and a second expected gain value can be obtained through a simulation experiment. During the simulation process, the specifications of the first RF switch, the second RF switch, the standard NTN transmit power amplifier, and the non-standard NTN transmit power amplifier can be obtained respectively, such as the rated power, resistance, etc. of each device, and a RF terminal with the same system structure as shown in Figure 3 is constructed during the simulation process, and the specifications of the simulated devices are made the same as the actual specifications. When the standard NTN power amplifier branch is connected, the branch gain value and the path loss value of the standard NTN power amplifier branch are obtained, and the second expected gain value is obtained by calculating the sum of the branch gain value and the path loss value. Similarly, the first expected gain value can be obtained. It should be noted that the obtained first expected gain value and the second expected gain value can be saved in the memory of the RF terminal. In subsequent use, the first expected gain value and the second expected gain value can be directly called in the memory of the RF terminal.

[0076] In addition, in order to ensure that the first expected gain value and the second expected gain value are more accurate, multiple simulation experiments can be performed, and the average values ​​of the first expected gain values ​​(second expected gain values) obtained from the multiple simulation experiments can be calculated respectively, and the average values ​​can be used as the final first expected gain value (second expected gain value).

[0077] In step S402, the first output power refers to the expected output power of the transmitted signal in the non-standard NTN power amplification branch. Here, the first output power can be used as the expected output power that the non-standard NTN power amplification branch wants to achieve, and the first output power can be known.

[0078] As shown in the block diagram of the RF terminal in Figure 3, it can be obtained that: (1) The input signals of the standard NTN power amplifier branch and the non-standard NTN power amplifier branch are the output signals of the NTN RF transceiver chip. Therefore, the input power of the input signals of the two branches is the same. (2) The output power of the standard NTN power amplifier branch is the product of the input power and the amplification factor of the standard NTN transmission power amplifier. (3) The output power of the non-standard NTN power amplifier branch is the product of the input power and the amplification factor of the non-standard NTN transmission power amplifier (and the amplification factor of the low-noise amplifier). Since the output power of the non-standard NTN power amplifier branch is generally greater than the output power of the standard NTN power amplifier branch, under the premise that the input power of the two branches is the same, the amplification factor of the non-standard NTN transmission power amplifier is greater than the amplification factor of the standard NTN transmission power amplifier.

[0079] In one example, the fourth output power can be determined by the first output power and the expected gain difference. The fourth output power is the expected output power of the transmitted signal in the standard NTN power amplifier branch. For example, if the first output power is 37 dBm and the expected gain difference is 17 dB, the fourth output power is the difference between 37 dBm and 17 dB, i.e., 20 dBm.

[0080] After the value of the fourth output power is known, the second input power corresponding to the fourth output power can be determined. In one example, the second input power corresponding to the fourth output power can be found through the pre-stored second configuration information. For example, after querying the second configuration information, it is found that the second input power corresponding to the fourth output power of 20dBm is -6dBm. In another example, the second input power corresponding to the fourth output power can also be found through a pre-stored function relationship, for example, the fourth output power is substituted into the pre-stored function relationship to obtain the solution of the function. Afterwards, the non-standard NTN power amplifier branch is turned on, and the output power (fifth output power) of the non-standard NTN power amplifier branch when the transmitted signal is under the second input power can be measured to determine the output power of the transmitted signal in the non-standard NTN power amplifier branch under the second input power. The specific method of measuring the fifth output power is not limited in this embodiment. For example, the fifth output power can be measured by a power meter or an existing RF power measuring device. For example, the first RF switch selects the contact corresponding to the non-standard NTN power amplification branch, the non-standard NTN power amplification branch is turned on, and when the second input power is -6dBm, the fifth output power is 36.5dBm as measured by a power meter.

[0081] That is, the fifth output power is the output power of the transmit signal in the non-standard NTN power amplifier branch at the second input power, while the fourth output power is the output power of the transmit signal in the standard NTN power amplifier branch at the second input power. In one example, the absolute value of the difference between the fifth output power and the fourth output power is calculated, and this absolute value is the actual gain difference. For example, the absolute value of the difference between the fifth output power of 36.5 dBm and the fourth output power of 20 dBm is calculated to obtain an actual gain difference of 16.5 dB.

[0082] In this embodiment, the process of obtaining the actual gain difference requires reference to the input power and output power of the standard NTN power amplification branch in the second configuration information. That is, power calibration of the non-standard NTN power amplification branch requires the use of the power data of the standard NTN power amplification branch. Therefore, the power data of the standard NTN power amplification branch can be used by both the non-standard NTN power amplification branch and the standard NTN power amplification branch to perform power calibration of the non-standard NTN power amplification branch. This reduces the impact of software data results during the power calibration process, simplifies the power calibration method, and makes it applicable to a variety of other branches.

[0083] In step S403, referring to the method for determining the fourth output power in step S402, a third output power can be determined based on the first output power and the actual gain difference. The third output power is the actual output power of the transmitted signal in the standard NTN power amplifier branch. For example, the first output power of 37 dBm is subtracted from the actual gain difference of 16.5 dB to obtain a third output power of 20.5 dBm.

[0084] In one example, the first input power can be determined in the second configuration information based on the third output power and the second configuration information. For example, the input power corresponding to the third output power, that is, the first input power, is directly searched in the second configuration information; for another example, the functional relationship between the input power and the output power in the second configuration information is obtained, and the third output power is substituted into the functional relationship to determine the first input power. For example, when the third output power is 20.5dBm, it is determined that the first input power corresponding to the third output power is -4.5dBm. Since the third output power is determined by the difference between the first output power and the actual gain, and the third output power corresponds to the first input power, when the standard NTN power amplifier branch outputs the third output power and the non-standard NTN power amplifier branch outputs the first output power, the first input power is also the input power corresponding to the first output power. It should be noted that the first output power is the ideal output power (expected output power) corresponding to the first input power.

[0085] Therefore, to determine whether power calibration of the non-standard NTN power amplifier branch is necessary, it is necessary to obtain the second output power of the transmitted signal at the first input power. The second output power is the actual output power of the transmitted signal in the non-standard NTN power amplifier branch. The first output power and the second output power correspond to the same input power, namely the first input power. Specifically, the second output power is the actual output power of the transmitted signal in the non-standard NTN power amplifier branch. Therefore, the second output power can be measured using existing power measurement equipment, such as a power meter or an existing RF power meter. For example, when the first input power is -4.5 dBm, the measured second output power is 37.5 dBm.

[0086] In step S404, after determining the actual output power and the expected output power corresponding to the transmission signal in the non-standard NTN power amplification branch at the first input power, the power of the transmission signal in the non-standard NTN power amplification branch can be calibrated based on the actual output power and the expected output power.

[0087] In one example, the first output power and the second output power can be compared. When the difference between the first output power and the second output power is greater than a preset threshold, it is determined that the power of the transmitted signal in the non-standard NTN power amplifier branch needs to be calibrated. Conversely, when the difference between the first output power and the second output power is less than or equal to the preset threshold, it is determined that the power of the transmitted signal in the non-standard NTN power amplifier branch does not need to be calibrated. For example, if the preset threshold is 1 dBm, when the first output power is 37 dBm and the second output power is 37.5 dBm, the difference between the first output power and the second output power is 0.5 dBm. In this case, 0.5 dBm is less than the preset threshold, and it is determined that the power of the transmitted signal in the non-standard NTN power amplifier branch does not need to be calibrated. Conversely, if the difference between the first output power and the second output power is 2 dBm, it is determined that the power of the transmitted signal in the non-standard NTN power amplifier branch needs to be calibrated.

[0088] It should be noted that when it is determined that the power of the transmitted signal in the non-standard NTN power amplification branch needs to be calibrated, it indicates that there is a significant deviation between the actual output power and the expected output power of the first input power, and the first input power cannot correspond to the expected output power. Therefore, in one example, the power of the transmitted signal in the non-standard NTN power amplification branch can be calibrated by continuously adjusting the first input power to reduce the difference between the actual output power and the expected output power of the first input power, thereby determining the first input power corresponding to the first output power. For example, the first input power can be adjusted so that the difference between the actual output power and the expected output power is less than or equal to a preset threshold, and the first input power is determined when the difference between the actual output power and the expected output power is less than or equal to the preset threshold, and the adjusted first input power is associated with the first output power. In addition, for the first input power that does not correspond to the first output power, a second output power having a difference less than or equal to the preset threshold can be used to associate the second output power with the first output power.

[0089] In one example, the power of the transmitted signal in the non-standard NTN power amplifier branch can be calibrated for a portion of the input power and output power, or for all of the input power and output power. Furthermore, to shorten the overall calibration time of the terminal device, calibration can be performed only for a portion of the input power and output power.

[0090] This embodiment can implement power calibration of the standard NTN power amplification branch and the non-standard NTN power amplification branch through the expected gain difference and the actual gain difference between the standard NTN power amplification branch and the non-standard NTN power amplification branch, thereby ensuring the accuracy of the input power and output power of the radio frequency terminal compatible with the standard NTN terminal and the non-standard NTN terminal, thereby ensuring that the satellite can successfully analyze the transmitted signal and complete smooth communication between the terminal and the satellite.

[0091] According to an exemplary embodiment, as shown in FIG5 , the power calibration method in this embodiment includes:

[0092] S501: Determine an expected gain difference.

[0093] S502: Determine an actual gain difference based on the expected gain difference and the first output power.

[0094] S503: Determine a second output power based on the actual gain difference and the first output power.

[0095] S504: Determine an output power error value based on the first output power and the second output power.

[0096] S505: Determine whether it is necessary to calibrate the power of the transmission signal in the non-standard NTN power amplification branch. If yes, execute step S507; if not, execute step S506.

[0097] S506: Determine first configuration information based on the first input power and the first output power.

[0098] S507: Adjust the first input power until the output power error value is within a preset range.

[0099] S508: Determine first configuration information based on the adjusted first input power and first output power.

[0100] S509: Calibrate the power of the transmitted signal in the non-standard NTN power amplification branch based on the first configuration information.

[0101] Among them, steps S501-S503 are the same as steps S401-S403 in the above embodiment and are not repeated here.

[0102] In step S504, the error value may refer to an absolute error, that is, the difference between the measured value and the ideal value. In addition, the error value may also refer to a relative error, that is, the ratio of the absolute error to the ideal value. The relative error is usually expressed as a percentage, and the relative error can characterize the accuracy of the measured value relative to the ideal value. Taking the error value as an absolute error as an example, the difference between the two output powers can be calculated using the first output power and the second output power, and the difference can be used as the output power error value. It should be noted that the difference is a positive number equal to or greater than 0, that is, when the difference is a negative number, it is necessary to obtain the absolute value of the difference as the error value.

[0103] In step S505, in one example, when the output power error value is an absolute error, it can be determined whether the output power error is within a preset range, and further, whether the power of the transmitted signal in the non-standard NTN power amplification branch needs to be calibrated. This embodiment does not limit the value range of the preset range; the preset range can be a custom error range. Specifically, when the output power error is within the preset range, it indicates that the power of the transmitted signal in the non-standard NTN power amplification branch does not need to be calibrated. Conversely, when the output power error is outside the preset range, it indicates that the power of the transmitted signal in the non-standard NTN power amplification branch needs to be calibrated.

[0104] In another example, when the output power error value is a relative error, the relationship between the output power error value and a preset value can be determined to determine whether the power of the transmitted signal in the non-standard NTN power amplifier branch needs to be calibrated. The preset value can be set and modified according to actual needs. Specifically, when the output power error value is greater than the preset value, it indicates that the accuracy of the actual output power relative to the expected output power is sufficiently large, and therefore, the power of the transmitted signal in the non-standard NTN power amplifier branch does not need to be calibrated. Conversely, when the output power error value is less than or equal to the preset value, it indicates that the accuracy of the actual output power relative to the expected output power is not large enough, and therefore, the power of the transmitted signal in the non-standard NTN power amplifier branch needs to be calibrated.

[0105] In step S506, if it is determined that the power of the transmitted signal in the non-standard NTN power amplification branch does not need to be calibrated, the first output power can be determined as the expected output power of the transmitted signal at the first input power. In one example, an association between the first input power and the first output power can be set and stored in the first configuration information. In this way, in an application, if the output power of the transmitted signal in the non-standard NTN power amplification branch is the first output power, the input power of the transmitted signal can be directly determined to be the first input power.

[0106] In step S507, if it is determined that the power of the transmit signal in the non-standard NTN power amplification branch needs to be calibrated, it means that the first output power cannot be used as the expected output power of the transmit signal at the first input power. Therefore, the first input power can be adjusted (e.g., increased or decreased), and the output power of the transmit signal at the adjusted first input power (hereinafter referred to as the target output power) is determined until the output power error between the target output power and the first output power falls within a preset range.

[0107] For example, the first output power determined by steps S501-S504 is 10 dBm, the first input power is -2 dBm, the second output power is 11.5 dBm, the output power error value is 1.5 dBm, and the preset range is [0, 0.5]. The output power error value is outside the preset range, so it is necessary to calibrate the power of the transmitted signal in the non-standard NTN power amplifier branch.

[0108] Specifically, since the second output power is greater than the first output power, that is, the input power corresponding to the first output power should be less than the first input power. The adjustment process of the first input power in step S507 can be: (1) reducing the first input power, for example, adjusting the first input power to -3dBm. (2) measuring the output power (target output power) of the transmitted signal under the reduced first input power, for example, the target output power is 11dBm, and the output power error value is calculated to be 1dBm. 1dBm is outside the preset range, so it is still necessary to calibrate the power of the transmitted signal in the non-standard NTN power amplifier branch. (3) continuing to reduce the first input power, for example, adjusting the first input power to -3.5dBm, measuring the target output power to 10.5dBm, and calculating the output power error value to 0.5dBm. 0.5dBm is within the preset range. In this way, it can be determined that the adjusted first input power is -3.5dBm.

[0109] In step S508, when the output power of the transmitted signal at the adjusted first input power and the output power error value of the first output power meet a preset condition (the output power error value is within a preset range), the first output power can be used as the expected output power of the transmitted signal at the adjusted first input power. In one example, an association relationship between the adjusted first input power and the first output power can be set, and the association relationship can be stored in the first configuration information.

[0110] In step S509, by looping through steps S501-S508, this embodiment can establish associations between multiple input powers and output powers of the transmit signal in the non-standard NTN power amplifier branch. For example, an input power of -3.5 dBm corresponds to an output power of 10 dBm, an input power of -4 dBm corresponds to an output power of 9 dBm, an input power of -9 dBm corresponds to an output power of 2 dBm, and so on. In this way, during subsequent use, the input power or output power of the transmit signal in the non-standard NTN power amplifier branch can be calibrated based on the first configuration information. For example, if the expected output power of the transmit signal is known to be 10 dBm, the input power of the transmit signal can be directly determined to be -3.5 dBm.

[0111] This embodiment provides a specific method for calibrating the power of a transmitted signal in a non-standard NTN power amplifier branch. By comparing the first output power with the second output power, the first input power can be calibrated, and the calibrated first input power corresponding to the first output power can be determined. This allows for the correspondence between multiple input and output powers of the transmitted signal to be determined, thereby obtaining the first configuration information. In practice, after the non-standard NTN power amplifier branch is turned on, the output power can be calibrated directly based on the input power of the transmitted signal in the non-standard NTN power amplifier branch, or the input power can be calibrated based on the output power of the transmitted signal in the non-standard NTN power amplifier branch. This allows for convenient and quick power calibration of the transmitted signal in the non-standard NTN power amplifier branch.
