It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is only to describe the distinction mode adopted by the objects of the same attributes when describing in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.
[0053] The present application discloses a power regulation method, and its flow chart is as follows: Figure 1 As shown, including:
[0054] Step S11, determining the working state of a power amplifier component of the electronic device, where the power amplifier component at least includes a first power amplifier and a second power amplifier;
[0055] Step S12: If it is determined that the magnetic field noise generated when the power amplification component is working meets the first preset condition, the current transmission power of the first power amplifier is adjusted to the first transmission power, and the current transmission power of the second power amplifier is adjusted to the second transmission power, so that the target part of the electronic device meets the second preset condition.
[0056] When an electronic device is in use, if the transmission power of the power amplifier is inappropriate, a certain magnetic field noise will be generated, thereby affecting the normal use of other devices around the electronic device, or affecting the normal use of other components in the electronic device.
[0057] Based on this, in this scheme, when it is determined that the magnetic field noise generated when the power amplification component is working meets the first preset condition, the transmission power of the first power amplifier and the second power amplifier in the power amplification component is adjusted so that the target part of the electronic device meets the second preset condition, that is, it is ensured that the target part of the electronic device can be used normally and avoid being interfered by the magnetic field noise; in addition, when the devices on the electronic device are not interfered by the magnetic field noise, the magnetic field interference to other devices around the electronic device will also be relatively small.
[0058] Specifically, during the use of an electronic device, it is necessary to determine the working status of a power amplifier component of the electronic device so that when it is determined that the transmission power of the power amplifier component needs to be adjusted, it can be determined based on its working status which one or several power amplifiers in the power amplifier component need to have their transmission power adjusted.
[0059] The power amplification component in the electronic device may include one power amplifier or multiple power amplifiers. When the power amplification component includes multiple power amplifiers, different power amplifiers are in different working states when the electronic device is in different scenarios.
[0060] Since the power amplifiers in working state in electronic devices are different in different scenarios, it is necessary to first determine the working state of the power amplifying component of the electronic device, that is, determine the power amplifier in the power amplifying component that is currently in working state, such as: the power amplifier in the current working state may be: the first power amplifier and the second power amplifier, or may be: the third power amplifier and the fourth power amplifier, or may be: the third power amplifier; or, determine the working mode of the power amplifier in the power amplifying component of the electronic device that is in working state.
[0061] Furthermore, in the power regulation method disclosed in this embodiment, determining the working state of the power amplification component of the electronic device includes at least one of the following:
[0062] The working state of the power amplifying component of the electronic device is determined based on the device shape of the electronic device; the working state of the power amplifying component of the electronic device is determined based on the distance between the user and the electronic device; the working state of the power amplifying component of the electronic device is determined based on the working frequency band of the electronic device.
[0063] To determine the working status of the power amplification component of an electronic device, it can be determined based on the device shape of the electronic device, based on the distance between the user and the electronic device, or based on the frequency band in which the device is currently located; in addition, it can also be determined based on the current working scenario.
[0064] If the device form of the electronic device is changeable, then when the electronic device is in different device forms, the working state of the power amplifying component in the electronic device is different. Therefore, the working state of the power amplifying component of the electronic device can be determined based on the device form of the electronic device.
[0065] The electronic device with a changeable device form may be: a foldable electronic device, a rollable electronic device, etc.
[0066] Taking a foldable electronic device as an example, if the shape of the electronic device changes during use, such as switching from a folded state to an unfolded state, at this time, the power amplifier in the working state in the electronic device may not have changed, but the working mode of the power amplifier in the working state needs to change with the change in the shape of the device. Therefore, when determining that the shape of the device has changed, it is necessary to determine the working mode of the power amplifier in the working state after the change. When the power amplifier is in different working modes, its corresponding transmission power may be different. When the working mode changes, the transmission power changes accordingly. Therefore, after determining that the shape of the device has changed, it is necessary to further determine whether the magnetic field noise generated by the power amplifier after the working mode changes during operation meets the first preset condition, and when it is determined that it meets the first preset condition, the transmission power of the power amplifier is adjusted.
[0067] In addition, the working state of the power amplifying component of the electronic device may also be determined based on the distance between the user and the electronic device.
[0068] The distance between the user and the electronic device is different, and the working mode of the power amplifier in the working state is different, for example, when the distance between the user and the electronic device is in a first range, the power amplifier in the working state is in a first working mode, and when the distance between the user and the electronic device is in a second range, the power amplifier in the working state is in a second working mode. The difference between the first working mode and the second working mode may include parameters such as transmission power, efficiency, and conduction angle.
[0069] Secondly, the working state of the power amplifying component of the electronic device can also be determined based on the working frequency band of the electronic device.
[0070] When the electronic device is in different operating frequency bands, the power amplifier in the working state in the electronic device may change. For example, when the electronic device is operating in a high frequency band, the power amplifier in the working state may include: N41; when the electronic device is operating in an ultra-high frequency band, the power amplifier in the working state may include: N77, etc.
[0071] In addition, the working state of the power amplifier component of the electronic device can also be determined based on the working scenario of the electronic device. When the electronic device is in different working conditions, the power amplifier in the working state may change. For example, in a high energy efficiency scenario, a high energy efficiency power amplifier in the electronic device needs to be selected to work, such as a Class D power amplifier in the electronic device; in a high bandwidth scenario, a high bandwidth power amplifier in the electronic device needs to be selected to work, such as a power amplifier QM77050 in the electronic device.
[0072] If it is determined that at least two power amplifiers are currently in a working state in the power amplification component, such as: a first power amplifier and a second power amplifier, at this time, it is necessary to further determine the magnetic field noise generated when the power amplification component is working. If it is determined that the magnetic field noise generated when the power amplification component is working meets the first preset condition, it is necessary to adjust the transmission power of the first power amplifier and the second power amplifier in the working state in the power amplification component, and adjust the transmission power of the first power amplifier from its current transmission power to the first transmission power, and adjust the transmission power of the second power amplifier from its current transmission power to the second transmission power.
[0073] When the magnetic field noise generated by the power amplifier component during operation meets the first preset condition, the transmission power of the power amplifier in the power amplifier component is adjusted so that the target part of the electronic device meets the second preset condition. The target part of the electronic device is a device or area on the electronic device that will be affected by the magnetic field noise, and because the target part is affected by the magnetic field noise, the user's use of the electronic device is affected, that is, the user's experience of using the electronic device is affected.
[0074] Therefore, when it is determined that the magnetic field noise generated when the power amplifier component is working meets the first preset condition, the transmission power of the power amplifier in the power amplifier component of the electronic device that is in a working state is adjusted to ensure that the target part can meet the second preset condition, thereby avoiding the target part from being affected by the magnetic field noise generated when the power amplifier is working, so as to ensure the user experience of the electronic device.
[0075] The power regulation method disclosed in this embodiment determines the working state of the power amplification component of the electronic device, and the power amplification component includes at least a first power amplifier and a second power amplifier; if it is determined that the magnetic field noise generated when the power amplification component is working meets the first preset condition, the current transmission power of the first power amplifier is adjusted to the first transmission power, and the current transmission power of the second power amplifier is adjusted to the second transmission power, so that the target part of the electronic device meets the second preset condition. When the working state of the power amplification module of the electronic device is determined, and it is determined that the magnetic field noise generated when the power amplification module is working meets the first preset condition, the power amplifier in the power amplification module is adjusted accordingly to ensure that the target part of the electronic device can meet the second preset condition, so that when the electronic device is working, other devices in the electronic device can also work normally to avoid being interfered by the magnetic field noise.
[0076] Furthermore, in the power regulation method disclosed in this embodiment, the magnetic field noise generated by the power amplification component when working satisfies the first preset condition, which may include at least one of the following:
[0077] The magnetic field noise generated by the power amplifier component when working is greater than the target value;
[0078] The working state of the power amplifier component changes.
[0079] If the magnetic field noise generated when the power amplifier component is working satisfies the first condition that the magnetic field noise generated when the power amplifier component is working is greater than the target value, then as long as it is determined that the magnetic field noise generated when the power amplifier component is working is greater than the target value, the transmission power of the first power amplifier and the second power amplifier in the working state is adjusted so that the magnetic field noise generated when the power amplifier component is working after the transmission power is adjusted is not greater than the target value.
[0080] That is, the transmitting power of the power amplifier will be adjusted only when it is determined that the magnetic field noise generated when the power amplifier component is working is greater than the target value. When the magnetic field noise generated when the power amplifier component is working is not greater than the target value, there is no need to adjust the transmitting power of the power amplifier, thereby ensuring that the magnetic field noise can always be within the range that enables the target component to meet the second preset condition.
[0081] For example, if the target value is -38dBm, that is, as long as the magnetic field noise generated by the power amplifier component when it is working is not greater than -38dBm, it can be ensured that the target component meets the second preset condition. Therefore, when the electronic device is working, the magnetic field noise generated by the power amplifier component when it is working is determined, and after the magnetic field noise generated by the power amplifier component when it is working is obtained, it is compared with the target value of -38dBm. If the magnetic field noise generated by the power amplifier component when it is working exceeds -38dBm, it is necessary to adjust the transmission power of the power amplifier to reduce the magnetic field noise when the power amplifier component is working so that it does not exceed -38dBm; if the magnetic field noise generated by the power amplifier component when it is working does not exceed -38dBm, continue to monitor the value of the magnetic field noise generated by the power amplifier component when it is working.
[0082] Specifically, the magnetic field noise generated by the power amplifying component when it is working is greater than the target value, which can be specifically as follows: the magnetic field noise detected at the target position when the power amplifying component is working is greater than the target value, that is, the power amplifying component generates magnetic field noise when it is working. In this embodiment, the magnetic field noise at all positions of the electronic device is not detected, nor is the maximum value of the magnetic field noise generated by the power amplifying component when it is working. Instead, only the magnetic field noise at the target position of the electronic device is detected. Only when the magnetic field noise at the target position is greater than the target value, the transmission power of the power amplifier in the power amplifying component that is in a working state is adjusted to reduce the magnetic field noise at the target position so that it is not greater than the target value.
[0083] The target position of the electronic device may be: the position of the target part of the electronic device. When the magnetic field noise at the position of the target part is not greater than the target value, it can be ensured that the target part meets the second preset condition.
[0084] In addition, if the magnetic field noise generated when the power amplifier component is working satisfies the first condition that the working state of the power amplifier component changes, then as long as it is determined that the working state of the power amplifier component has changed, the transmission power of the first power amplifier and the second power amplifier in the working state is adjusted so that the magnetic field noise generated when the power amplifier component is working after the transmission power is adjusted does not meet the first preset condition.
[0085] That is, the transmit power of the power amplifier is adjusted only when it is determined that the working state of the power amplifier component has changed, and when the working state of the power amplifier component has not changed, there is no need to adjust the transmit power of the power amplifier.
[0086] When the working state of the power amplifier component changes, the magnetic field noise generated by the power amplifier component during operation will also change. At this time, the transmit power of the power amplifier is adjusted. Based on the adjustment of the transmit power of the power amplifier, the magnetic field noise generated by the power amplifier component when maintaining the current working state can always remain unchanged. Since the transmit power of the power amplifier is adjusted when the working state of the power amplifier component changes, it is ensured that the target part meets the second preset condition. Then, when the power amplifier component always maintains the current working state, the magnetic field noise generated by the power amplifier component during operation will not change, thereby ensuring that as long as the working state of the power amplifier component does not change, the magnetic field noise can always be within the range that enables the target part to meet the second preset condition.
[0087] Accordingly, in the power adjustment method disclosed in this embodiment, the target part of the electronic device satisfies the second preset condition, which may include at least one of the following:
[0088] The radiation and receiving performance of the antenna of the electronic device meets the requirements of wireless communication; the magnetic field noise received by the receiver of the electronic device meets the hearing aid compatibility requirements; the specific absorption rate of the target area of the electronic device is lower than the preset threshold.
[0089] The target part of the electronic device may be an antenna, a receiver, or a target area of the electronic device.
[0090] If the target component of the electronic device is an antenna, it is necessary to ensure that the radiation and reception performance of the antenna meet the requirements of wireless communication, that is, to ensure the OTA (Over The Air) performance of the antenna. The OTA performance of the antenna refers to the total radiation performance of the antenna in a wireless air interface environment, specifically including the transmission and reception capabilities.
[0091] Since the RF signal amplified by the power amplifier component in the electronic device needs to be transmitted and output through the antenna to ensure that the RF signal output by the antenna can be effectively transmitted to the base station or other equipment, and the antenna can also receive external signals, then when the transmission power of the power amplifier in the power amplifier component is adjusted, the intensity of the antenna transmission signal will change accordingly, thereby affecting the total radiation power of the antenna, and the working efficiency and communication effect of the antenna will also be affected.
[0092] Therefore, when it is determined that the transmit power of the power amplifier in the power amplification component needs to be adjusted, it is necessary to ensure that the adjusted transmit power of the power amplifier does not affect the signal transmission of the antenna, that is, to ensure that the radiation and receiving performance of the antenna meets the wireless communication requirements.
[0093] For example: when it is determined that the magnetic field noise generated when the power amplification component is working is greater than the target value, it is necessary to adjust the transmission power of the first power amplifier and the second power amplifier in the power amplification component, such as reducing the transmission power of the first power amplifier and the second power amplifier, and it is necessary to ensure that the capacity of the RF signal output by the first power amplifier and the second power amplifier after the transmission power is reduced can ensure that the radiation and reception performance of the antenna are not affected, wherein the radiation and reception performance of the antenna are not affected, which can specifically be that the radiation and reception capabilities of the antenna are greater than a certain specific value.
[0094] If the target part of the electronic device is a receiver, it is necessary to ensure that the magnetic field noise received by the receiver meets the hearing aid compatibility requirements, that is, to ensure that the receiver can pass the HAC certification test. HAC (Hearing Aid Compatibility) certification is a certification standard for telecommunications equipment, especially wireless phones (such as mobile phones and wireless headsets). This standard applies to wireless communication devices (WDs) and hearing aids. It specifies the unified measurement methods and parameter requirements for the electromagnetic and operational compatibility of hearing aids and WDs operating in the range of 614MHz to 6GHz.
[0095] When an electronic device performs wireless communication, the power amplifier in the power amplification component of the electronic device outputs a radio frequency signal. In the process of the power amplifier outputting the radio frequency signal, magnetic field noise is generated. If the electronic device outputs audio during wireless communication, and the user of the electronic device is a user wearing a hearing aid, then the user wears a hearing aid and receives the audio output by the electronic device through the receiver of the electronic device. If the magnetic field noise generated by the power amplifier is large, it will affect the hearing aid, causing noise in the hearing aid or the user to be unable to hear the audio output by the receiver through the hearing aid. Therefore, after adjusting the transmission power of the power amplifier of the electronic device, the receiver can pass the HAC certification test, that is, the magnetic field noise felt by the receiver meets the hearing aid compatibility requirements.
[0096] For example: monitoring the working status of the power amplifier component in the electronic device. If the electronic device is currently working in the NR5G-N77 frequency band and it is determined that the working status has changed, the transmission power of the first power amplifier and the second power amplifier in the power amplifier component are adjusted. After the adjustment, the magnetic field at the location of the receiver is monitored. At this time, it is necessary to ensure that the magnetic field noise at the location of the receiver is less than -38dBm. If it is determined that the magnetic field noise at the location of the receiver is not less than -38dBm, it is necessary to continue to adjust the transmission power of the first power amplifier and the second power amplifier until the magnetic field noise generated during the operation of the power amplifier after adjustment is less than -38dBm.
[0097] Furthermore, the magnetic field at the location of the receiver is monitored, which can be specifically as follows: an area with the receiver as the center point is determined, and the magnetic field noise in this area is monitored. The area can be: a circular area with the receiver as the center point and a radius of 50mm. There can be multiple monitoring points in this area. If the number of monitoring points with magnetic field noise less than -38dBm accounts for a certain proportion, it can be determined that the magnetic field noise to which the receiver is subjected meets the hearing aid compatibility requirements.
[0098] If the target part of the electronic device is the target area of the electronic device, it is necessary to ensure that the specific absorption rate of the target area is lower than the preset threshold. Among them, the specific absorption rate SAR is used to measure the impact of electronic device radiation on the human body, and the amount of radiation is closely related to the uplink power of the electronic device.
[0099] When the transmission power of the power amplifier of the electronic device is adjusted, the value of the specific absorption rate SAR changes. At this time, it is necessary to detect the value of the specific absorption rate of the target area of the electronic device. If the value is greater than the preset threshold, it is necessary to continue to adjust the transmission power of the power amplifier of the electronic device. If the value is less than the preset threshold, there is no need to adjust the transmission power of the power amplifier of the electronic device.
[0100] This embodiment discloses a power regulation method, and its flow chart is as follows: Figure 2 As shown, including:
[0101] Step S21, determining the working state of a power amplifier component of the electronic device, where the power amplifier component at least includes a first power amplifier and a second power amplifier;
[0102] Step S22: if it is determined that the magnetic field noise generated when the power amplifying component is working satisfies the first preset condition, determine a first distance between the first power amplifier and the target component, and a second distance between the second power amplifier and the target component in the electronic device;
[0103] Step S23: if it is determined that the first distance is less than the second distance, the current transmission power of the first power amplifier is reduced to the first transmission power, and the current transmission power of the second power amplifier is increased to the second transmission power, so that the target part meets the second preset condition.
[0104] After determining the working state of the power amplifier component of the electronic device, if it is determined that the magnetic field noise generated when the power amplifier component is working meets the first preset condition, it indicates that the transmission power of the first power amplifier and the second power amplifier currently in the working state in the power amplifier component needs to be adjusted so that the target component meets the second preset condition.
[0105] The transmission power of the first power amplifier and the second power amplifier is adjusted, which may be specifically: determining which power amplifier needs to reduce the transmission power and which power amplifier needs to increase the transmission power based on the distance between the first power amplifier and the second power amplifier and the target part.
[0106] When it is determined that the magnetic field noise generated when the power amplifier component is working meets the first preset condition, no matter the first preset condition is that the magnetic field noise generated when the power amplifier component is working is greater than the target value, or the working state of the power amplifier component changes, it is necessary to adjust the transmission power of the first power amplifier and the second power amplifier in the working state so that the target part meets the second preset condition. Whether the target part meets the second preset condition is that the radiation and receiving performance of the antenna meets the wireless communication requirements, the magnetic field noise received by the receiver meets the hearing aid compatibility requirements, or the specific absorption rate of the target area is lower than the preset threshold, it is related to the transmission power of the power amplifier in the working state.
[0107] The higher the transmission power of the power amplifier in working state, the better the radiation and receiving performance of the antenna, the greater the magnetic field noise received by the receiver, and the higher the specific absorption rate of the target area. Therefore, on the basis of ensuring the radiation and receiving performance of the antenna, the magnetic field noise received by the receiver and the specific absorption rate of the target area must be lowered.
[0108] In order to reduce the magnetic field noise received by the receiver and the specific absorption rate of the target area, the transmission power of the power amplifier in the working state can be reduced. In order to ensure the radiation and receiving performance of the antenna, the transmission power of the power amplifier in the working state needs to be maintained in a certain state. Therefore, when it is determined that there are at least two power amplifiers in the working state, such as the first power amplifier and the second power amplifier, the transmission power of one of the power amplifiers can be reduced, and the transmission power of the other power amplifier can be increased.
[0109] Specifically, based on the distance between the two power amplifiers in working state and the receiver, it is determined which power amplifier has its transmission power reduced and which power amplifier has its transmission power increased. Of the two power amplifiers in working state, one is closer to the receiver and the other is farther from the receiver. If the transmission power of the power amplifier closer to the receiver is increased, the magnetic field noise received by the receiver will be greater. At this time, in order to reduce the magnetic field noise received by the receiver, the transmission power of the power amplifier farther from the receiver needs to be reduced more. However, on the basis of reducing the transmission power more, the magnetic field noise received by the receiver is still reduced less. If the transmission power of the power amplifier closer to the receiver is reduced, the magnetic field noise received by the receiver is reduced. In order to ensure the radiation and reception performance of the antenna, the transmission power of the power amplifier farther from the receiver can be increased.
[0110] Therefore, in this embodiment, it is necessary to first determine the distances between the two power amplifiers in working state and the target part, that is, the first distance between the first power amplifier and the target part, and the second distance between the second power amplifier and the target part; then, compare the first distance with the second distance; if the first distance is smaller than the second distance, reduce the transmission power of the first power amplifier and increase the transmission power of the second power amplifier; correspondingly, if the first distance is greater than the second distance, increase the transmission power of the first power amplifier and reduce the transmission power of the second power amplifier.
[0111] like Figure 3 As shown, the positional relationship between the first power amplifier, the second power amplifier and the target part in the electronic device includes: the first power amplifier PA0-N77-TX0, the second power amplifier PA1-N77-TX1, and the target part 31, and the target part 31 can be specifically a receiver. Among them, the first distance 32 between the first power amplifier PA0-N77-TX0 and the target part 31 is smaller than the second distance 33 between the second power amplifier PA1-N77-TX1 and the target part 31, so when adjusting the transmission power, the transmission power of the first power amplifier PA0-N77-TX0 can be reduced, and at the same time, the transmission power of the second power amplifier PA1-N77-TX1 can be increased.
[0112] Among them, reducing the transmission power of the first power amplifier is to reduce the current transmission power of the first power amplifier to the first transmission power, and increasing the transmission power of the second power amplifier is to increase the current transmission power of the second power amplifier to the second transmission power.
[0113] It should be noted that the current transmit power of the first power amplifier and the current transmit power of the second power amplifier may be the same or different, and the difference between the current transmit power of the first power amplifier and the first transmit power and the difference between the second transmit power and the current transmit power of the second power amplifier may be the same or different.
[0114] Furthermore, in the power adjustment method disclosed in this embodiment, determining the first transmit power and the second transmit power may be specifically as follows:
[0115] A power adjustment value is determined based on the first distance and the second distance; a first transmit power and a second transmit power are determined based on the power adjustment value, wherein the first transmit power is the difference between the current transmit power of the first power amplifier and the power adjustment value, and the second transmit power is the sum of the current transmit power of the second power amplifier and the power adjustment value.
[0116] The number of power amplifiers in the electronic device is fixed, the position of each power amplifier in the electronic device is fixed, and the distance between each power amplifier and the receiver is fixed (for electronic devices with variable device form, when the device form change is completed, the distance between each power amplifier and the receiver is also fixed).
[0117] Therefore, a relationship table can be set in advance, which records the power adjustment values corresponding to different working states of the power amplification components, such as: in the first working state, the power amplifiers in the working state are power amplifier 1 and power amplifier 2, and at this time, the corresponding power adjustment value is adjustment value 1; in the second working state, the power amplifiers in the working state are power amplifier 2 and power amplifier 3, and at this time, the corresponding power adjustment value is adjustment value 2, etc.
[0118] Alternatively, the power adjustment value may be determined based on adjustment values corresponding to the first distance and the second distance in the historical records.
[0119] After the power adjustment value is determined, a first transmit power and a second transmit power are determined based on the power adjustment value.
[0120] The current transmit power of the first power amplifier and the current transmit power of the second power amplifier are known. After the power adjustment value is determined, the first transmit power of the first power amplifier can be determined based on the current transmit power of the first power amplifier and the power adjustment value, and the second transmit power of the second power amplifier can be determined based on the current transmit power of the second power amplifier and the power adjustment value.
[0121] Specifically, since the first power amplifier needs to reduce the transmission power, the current transmission power of the first power amplifier is subtracted from the power adjustment value, and the result is the first transmission power; since the second power amplifier needs to increase the transmission power, the current transmission power of the second power amplifier is summed with the power adjustment value, and the result is the second transmission power.
[0122] For example: the current transmission power of the first power amplifier is 26db, the current transmission power of the second power amplifier is 26db, and the power adjustment value is 1db, then the transmission power of the first power amplifier is reduced to the first transmission power, the first transmission power is 25db, and the transmission power of the second power amplifier is increased to the second transmission power, the second transmission power is 27db.
[0123] In this case, the power adjustment values of the first power amplifier and the second power amplifier are the same, that is, one subtracts the power adjustment value from its current transmit power, and the other adds the power adjustment value to its current transmit power.
[0124] The power regulation method disclosed in the present embodiment, after determining the working state of the power amplifying component of the electronic device, if it is determined that the magnetic field noise generated when the power amplifying component is working meets the first preset condition, it is necessary to determine the power amplifier close to the target part based on the distances between the first power amplifier and the second power amplifier and the target part respectively, and reduce its transmission power. For the power amplifier far away from the target part, its transmission power is increased. By reducing the power amplifier close to the target part, the impact of the magnetic field noise on the target part is reduced. In order to ensure that the radio frequency signal sent by the power amplifying component can be transmitted normally, the transmission power of the power amplifier far away from the target part needs to be increased. Increasing the transmission power of the power amplifier far away from the target part can not only ensure the normal transmission of the radio frequency signal, but also reduce the impact of the magnetic field noise on the target part due to its long distance from the target part. On the premise of ensuring the communication quality, it is ensured that the target part meets the second preset condition, thereby improving the user experience.
[0125] This embodiment discloses a power regulation method, and its flow chart is as follows: Figure 4 As shown, including:
[0126] Step S41, determining the working state of a power amplifier component of the electronic device, where the power amplifier component at least includes a first power amplifier and a second power amplifier;
[0127] Step S42: if it is determined that the magnetic field noise generated when the power amplification component is working satisfies the first preset condition, determine the current total transmit power based on the current transmit power of the first power amplifier and the current transmit power of the second power amplifier;
[0128] Step S43: determining a first transmit power and a second transmit power based on the total transmit power;
[0129] Step S44, adjusting the current transmit power of the first power amplifier to the first transmit power, adjusting the current transmit power of the second power amplifier to the second transmit power, and the total transmit power of the first power amplifier and the second power amplifier remains unchanged, so that the target part of the electronic device meets the second preset condition.
[0130] After determining the working state of the power amplifier component of the electronic device, if it is determined that the magnetic field noise generated when the power amplifier component is working meets the first preset condition, it indicates that the transmission power of the first power amplifier and the second power amplifier currently in the working state in the power amplifier component needs to be adjusted so that the target component meets the second preset condition.
[0131] To adjust the transmit power of the first power amplifier and the second power amplifier, the first transmit power and the second transmit power must be determined first, and then the transmit power of the first power amplifier is adjusted to the first transmit power, and the transmit power of the second power amplifier is adjusted to the second transmit power.
[0132] Among them, the determination of the first transmission power and the second transmission power can be achieved based on the total transmission power. When the total transmission power remains unchanged, the first transmission power and the second transmission power are determined. When the first power amplifier transmits signals at the first transmission power and the second power amplifier transmits signals at the second transmission power, since their total transmission power remains unchanged, it will not affect the performance of the antenna receiving and radiating signals. In this case, the electronic device can still transmit signals normally.
[0133] Specifically, the current transmission power of the first power amplifier and the current transmission power of the second power amplifier are first determined. After determining the current transmission power of each power amplifier in the power amplification component in the electronic device that is in a working state, the current total transmission power of the electronic device can be determined based on the current transmission power of each power amplifier in a working state.
[0134] For example, the power amplifier components in the electronic device that are in working state are power amplifier 1 and power amplifier 2, wherein the current transmission power of power amplifier 1 is 26db, and the current transmission power of power amplifier 2 is 26db. Based on the determination method of the total transmission power, it can be determined that the current total transmission power of the electronic device is 29db;
[0135] For another example, the power amplifier components in the working state in the electronic device are power amplifier 1 and power amplifier 2, wherein the current transmission power of power amplifier 1 is 23.5 db, and the current transmission power of power amplifier 2 is 27.5 db. Based on the determination method of the total transmission power, it can be determined that the current total transmission power of the electronic device is 29 db;
[0136] For another example, the power amplifying components in working state in the electronic device are power amplifier 1 and power amplifier 2, wherein the current transmission power of power amplifier 1 is 23db, and the current transmission power of power amplifier 2 is 23db. Based on the method for determining the total transmission power, it can be determined that the current total transmission power of the electronic device is 26db.
[0137] When the transmit power of the power amplifier needs to be adjusted, after determining the current total transmit power of the electronic device, in order to ensure that the total transmit power of the electronic device remains unchanged, it is necessary to determine the first transmit power and the second transmit power based on the total transmit power, and then adjust the transmit power of the first power amplifier to the first transmit power, and adjust the transmit power of the second power amplifier to the second transmit power. Then, after adjusting the transmit power, the total transmit power of the electronic device does not change.
[0138] For example: the power amplifying components currently in working state in the electronic device are power amplifier 1 and power amplifier 2, wherein the current transmission power of power amplifier 1 is 26db, and the current transmission power of power amplifier 2 is 26db. Based on the method of determining the total transmission power, it can be determined that the current total transmission power of the electronic device is 29db. On the basis of ensuring that the total transmission power of the electronic device is still 29db, the current transmission powers of power amplifier 1 and power amplifier 2 are adjusted to obtain the first transmission power and the second transmission power, wherein the first transmission power can be 23.5db, and the second transmission power is 27.5db. At this time, the total transmission power of the electronic device is still 29db. Even if the transmission power of power amplifier 1 and power amplifier 2 changes, the total transmission power of the electronic device does not change.
[0139] Furthermore, in the power regulation method disclosed in this embodiment, the total transmission power of the electronic device is kept unchanged, which can be specifically: the change of the total transmission power of the electronic device is kept within a target range, that is, as the transmission power of the power amplifier changes, even if the total transmission power of the electronic device changes, the change amount is within the target range.
[0140] The target range may be [-0.2, +0.2], or [-0.1, +0.1], etc.
[0141] For example: taking the target range of [-0.1, +0.1] as an example, the power amplifier components currently in working state in the electronic device are power amplifier 1 and power amplifier 2, wherein the current transmission power of power amplifier 1 is 26db, and the current transmission power of power amplifier 2 is 26db. Based on the determination method of the total transmission power, it can be determined that the current total transmission power of the electronic device is 29db; on the basis of ensuring that the change in the total transmission power of the electronic device is within the range of [-0.1, +0.1], the current transmission power of power amplifier 1 and power amplifier 2 is adjusted to obtain the first transmission power and the second transmission power, wherein the first transmission power can be 25db, and the second transmission power can be 27db. At this time, the total transmission power of the electronic device is 29.1db, and the difference between the total transmission power of the electronic device after adjusting the transmission power and the total transmission power of the electronic device before adjusting the transmission power is 0.1, which is within the target range;
[0142] For another example: taking the target range of [-0.1, +0.1] as an example, the power amplification components currently in working state in the electronic device are power amplifier 1 and power amplifier 2, wherein the current transmission power of power amplifier 1 is 23.5db, and the current transmission power of power amplifier 2 is 27.5db. Based on the method for determining the total transmission power, it can be determined that the current total transmission power of the electronic device is 29db; on the basis of ensuring that the change in the total transmission power of the electronic device is within the range of [-0.1, +0.1], the current transmission power of power amplifier 1 and power amplifier 2 is adjusted to obtain a first transmission power and a second transmission power, wherein the first transmission power can be 24db, and the second transmission power is 27.5db. At this time, the total transmission power of the electronic device is 29.1db, and the difference between the total transmission power of the electronic device after adjusting the transmission power and the total transmission power of the electronic device before adjusting the transmission power is 0.1, which is within the target range.
[0143] For an electronic device in the N77 frequency band, with two transmitting antennas and four receiving antennas (2T4R), and with a circuit power of PC2 level, when it has two power amplifiers in operation, namely the first power amplifier and the second power amplifier, the corresponding relationship between the transmitting power of each power amplifier and the total transmitting power can be as follows: Figure 5As shown, TX0 (PA0) is the transmit power TX0 of the first power amplifier PA0, TX1 (PA1) is the transmit power TX1 of the second power amplifier PA1, and TX Total is the total transmit power, wherein, when the transmit power TX0 of the first power amplifier PA0 is 26db and the transmit power TX1 of the second power amplifier PA1 is 26db, the total transmit power TX Total is 29.0db; when the transmit power TX0 of the first power amplifier PA0 is 25db and the transmit power TX1 of the second power amplifier PA1 is 27db, the total transmit power TX Total is 29.1db; when the transmit power TX0 of the first power amplifier PA0 is 24db and the transmit power TX1 of the second power amplifier PA1 is 27.5db, the total transmit power TX Total is 29.1db; when the transmit power TX0 of the first power amplifier PA0 is 23.5db and the transmit power TX1 of the second power amplifier PA1 is 27.5db, the total transmit power TX Total is 29.0db.
[0144] The power adjustment method disclosed in this embodiment can first determine the current total transmission power of the first power amplifier and the second power amplifier when determining the working state of the power amplification component of the electronic device and determining that the magnetic field noise generated when the power amplification component is working meets the first preset condition, and determine the first transmission power and the second transmission power based on the total transmission power, so as to adjust the transmission power of the first power amplifier to the first transmission power and the transmission power of the second power amplifier to the second transmission power, so as to ensure that the total transmission power of the first power amplifier and the second power amplifier remains unchanged, so that the target part of the electronic device meets the second preset condition. This scheme determines the first transmission power and the second transmission power based on the total transmission power, ensuring that the total transmission power of the first power amplifier and the second power amplifier remains unchanged before and after the adjustment, so that the radiation and reception performance of the antenna meet the wireless communication requirements, and avoids the problem that the radiation and reception performance of the antenna are affected due to the adjustment of the transmission power of the first power amplifier and the second power amplifier.
[0145] This embodiment discloses a power regulation method, and its flow chart is as follows: Figure 6 As shown, including:
[0146] Step S61, determining the working state of a power amplifier component of the electronic device, where the power amplifier component at least includes a first power amplifier and a second power amplifier;
[0147] Step S62: if it is determined that the magnetic field noise generated when the power amplifying component is working satisfies the first preset condition, determine a first distance between the first power amplifier and the target component, and a second distance between the second power amplifier and the target component;
[0148] Step S63: If it is determined that the first distance is less than the second distance, the current transmission power of the first power amplifier is reduced by a first parameter value to obtain a first transmission power, and the current transmission power of the second power amplifier is reduced by a second parameter value to obtain a second transmission power, and the first parameter value is greater than the second parameter value, so that the target part meets the second preset condition.
[0149] After determining the working state of the power amplifier component of the electronic device, if it is determined that the magnetic field noise generated when the power amplifier component is working meets the first preset condition, it indicates that the transmission power of the first power amplifier and the second power amplifier currently in the working state in the power amplifier component needs to be adjusted so that the target component meets the second preset condition.
[0150] The adjustment of the transmission power of the first power amplifier and the second power amplifier may be different based on the different distances between the first power amplifier and the second power amplifier and the target part, that is, the closer the power amplifier is to the target part, the greater the reduction in its transmission power, and the farther the power amplifier is from the target part, the smaller the reduction in its transmission power.
[0151] If there are two working power amplifiers in an electronic device, and if the two power amplifiers are at the same distance from a target part, then the impact of the magnetic field noise generated by the two power amplifiers when they are working on the target part is related to the parameters of the target part.
[0152] If the parameters of two power amplifiers in a working state in an electronic device are the same and the distances from the target device are the same, then the magnetic field noise generated by the two power amplifiers when working has the same impact on the target device. When it is determined that the transmit power of the power amplifiers in a working state needs to be adjusted, the transmit power of the two power amplifiers can be reduced by the same parameter value at the same time, such as: the transmit power of the two power amplifiers is reduced by 1db; if the parameters of two power amplifiers in a working state in an electronic device are different, but the distances from the target device are the same, then the magnetic field noise generated by the two power amplifiers when working has different impact on the target device. When it is determined that the transmit power of the power amplifiers in a working state needs to be adjusted, the parameter values by which the transmit power of the two power amplifiers is reduced can be determined based on the parameters of the two power amplifiers, such as: the transmit power of one power amplifier is reduced by 1db, and the transmit power of the other power amplifier is reduced by 1.5db.
[0153] When the distances between two working power amplifiers and the target device are different in the electronic device, it is not necessary to consider whether the parameters of the two power amplifiers are the same, but only the distances between the two power amplifiers and the target device are used as a reference to determine how to adjust the transmission power of the power amplifiers.
[0154] When the distances between the two power amplifiers in operation and the target part are different, the closer the power amplifier is to the target part, the greater the impact of the magnetic field noise generated during its operation on the target part, while the farther the power amplifier is from the target part, the smaller the impact of the magnetic field noise generated during its operation on the target part.
[0155] Therefore, when it is determined that the transmission power of the power amplifier in the working state needs to be adjusted, if the transmission power of the power amplifier in the working state is to be reduced, in order to ensure the effect of reducing the transmission power of the power amplifier, the first power amplifier close to the target device needs to be reduced by a larger value, that is, the first parameter value; and in order to ensure the normal communication of the electronic device, it is necessary to ensure that the second power amplifier far from the target device can only be reduced by a smaller value, that is, the second parameter value, wherein the second parameter value is less than the first parameter value. In this way, both the effect of reducing the transmission power and the normal communication of the electronic device can be ensured.
[0156] For example: the distance between the first power amplifier and the target part is smaller than the distance between the second power amplifier and the target part. Then, when it is necessary to reduce the transmission power of the first power amplifier and the second power amplifier at the same time, the first parameter value corresponding to the first power amplifier needs to be greater than the second parameter value corresponding to the second power amplifier. For example, the first parameter value can be set to 1db, and the second parameter value can be set to 0.5db. The current transmission power of the first power amplifier is subtracted by 1db to obtain the first transmission power, and the current transmission power of the second power amplifier is subtracted by 0.5db to obtain the second transmission power.
[0157] In addition, if it is necessary to increase the transmission power of a power amplifier in working state, the transmission power of the first power amplifier and the transmission power of the second power amplifier in working state can be increased at the same time. However, the increase value of each power amplifier needs to be determined based on the distance from the target part. The distance between the power amplifier and the target part is different, and the increase value of the transmission power is also different.
[0158] Therefore, when it is determined that the transmission power of the power amplifier in the working state needs to be adjusted, if the transmission power of the power amplifier in the working state is to be increased, in order to ensure the effect of increasing the transmission power of the power amplifier, a larger parameter value, that is, the fourth parameter value, needs to be added for the second power amplifier that is farther away from the target part; and in order to ensure the normal communication of the electronic device and avoid the target part being subjected to excessive magnetic field noise generated by the power amplifier when it is working, a smaller parameter value, that is, the third parameter value, needs to be added for the first power amplifier that is close to the target part, wherein the third parameter value is less than the fourth parameter value. In this way, the effect of increasing the transmission power can be ensured, and the magnetic field noise generated by the power amplifier when it is working can be avoided, thereby ensuring the normal communication of the electronic device.
[0159] For example: the distance between the first power amplifier and the target part is smaller than the distance between the second power amplifier and the target part. Then, when it is necessary to increase the transmission power of the first power amplifier and the second power amplifier at the same time, the third parameter value corresponding to the first power amplifier needs to be smaller than the fourth parameter value corresponding to the second power amplifier. For example, the third parameter value can be set to 0.3db, and the fourth parameter value can be set to 0.5db. The current transmission power of the first power amplifier is increased by 0.3db to obtain the first transmission power, and the current transmission power of the second power amplifier is increased by 0.5db to obtain the second transmission power.
[0160] After adjusting the transmission power of the power amplifier, the normal communication of the electronic device is ensured, that is, the change in the total transmission power of the power amplifier component of the electronic device is ensured not to exceed a certain specific range.
[0161] The power regulation method disclosed in the present embodiment can determine the first distance and the second distance between the first power amplifier and the second power amplifier in the working state and the target part respectively when determining the working state of the power amplification component of the electronic device and determining that the magnetic field noise generated when the power amplification component is working satisfies the first preset condition, and when the first distance is smaller than the second distance, the transmission power of the first power amplifier is reduced by a larger value, and the transmission power of the second power amplifier is reduced by a smaller value, so that the transmission power of the power amplifier closer to the target part is reduced by a larger value, and the transmission power of the power amplifier farther from the target part is reduced by a smaller value, so as to reduce the influence of the magnetic field noise generated when the power amplification component of the electronic device is working on the target part while ensuring the normal operation of the power amplifier of the electronic device.
[0162] This embodiment discloses a power regulation method, and its flow chart is as follows: Figure 7 As shown, including:
[0163] Step S71, determining the working state of a power amplifier component of the electronic device, where the power amplifier component at least includes a first power amplifier and a second power amplifier;
[0164] Step S72: if it is determined that the magnetic field noise generated by the power amplification component when it is working meets the first preset condition, determine the distance between the user and the electronic device;
[0165] Step S73: if the distance between the user and the electronic device is greater than the target threshold, determine the first adjustment mode, and adjust the current transmit power of the first power amplifier to the first transmit power and the current transmit power of the second power amplifier to the second transmit power based on the first adjustment mode;
[0166] Step S74: If the distance between the user and the electronic device is less than the target threshold, determine the second adjustment mode, adjust the current transmission power of the first power amplifier to the first transmission power based on the second adjustment mode, and adjust the current transmission power of the second power amplifier to the second transmission power, and the first magnetic field noise generated when the power amplification component adjusted by the first adjustment mode is working is greater than the second magnetic field noise generated when the power amplification component adjusted by the second adjustment mode is working.
[0167] After determining the working state of the power amplifier component of the electronic device, if it is determined that the magnetic field noise generated when the power amplifier component is working meets the first preset condition, it indicates that the transmission power of the first power amplifier and the second power amplifier currently in the working state in the power amplifier component needs to be adjusted so that the target component meets the second preset condition.
[0168] The adjustment of the transmission power of the first power amplifier and the second power amplifier may be different based on the distance between the user and the electronic device.
[0169] First, the distance between the user and the electronic device is determined. The distance can be detected by sensors on the electronic device, such as: distance sensors, infrared sensing devices, image acquisition devices, audio acquisition devices, etc.
[0170] If the distance between the user and the electronic device is greater than the target threshold, it indicates that the distance between the user and the electronic device is relatively large. At this time, the magnetic field noise generated when the electronic device is working has a relatively small impact on the user. Therefore, when adjusting the transmission frequency of the power amplifier in the working state in the electronic device, the adjustment amplitude may be relatively small, so that the magnetic field noise generated by the power amplifier in the working state after the adjustment is reduced, and the reduction amplitude is relatively small, so that on the basis of ensuring that the user is not affected by the magnetic field noise, the transmission frequency of the power amplifier is reduced as small as possible, so as to reduce the situation where the communication quality of the electronic device is affected by reducing the transmission power of the power amplifier;
[0171] If the distance between the user and the electronic device is less than the target threshold, it means that the distance between the user and the electronic device is small. At this time, the magnetic field noise generated when the electronic device is working has a greater impact on the user. Therefore, when adjusting the transmission frequency of the power amplifier in the working state in the electronic device, the adjustment range can be larger, so as to minimize the impact of the magnetic field noise generated when the electronic device is working on the user while ensuring the communication quality of the electronic device.
[0172] That is, the first adjustment mode or the second adjustment mode is determined based on the distance between the user and the electronic device. Different adjustment modes have different adjustment amplitudes on the transmission frequency of the power amplifier. However, regardless of the first adjustment mode or the second adjustment mode, the magnetic field noise felt by the user can be reduced after adjustment.
[0173] If the distance between the user and the electronic device is greater than the target threshold, the first adjustment mode is determined. If the distance between the user and the electronic device is less than the target threshold, the second adjustment mode is determined. The adjustment amplitude of the transmission frequency of the power amplifier in the first adjustment mode is smaller than the adjustment amplitude of the transmission frequency of the power amplifier in the second adjustment mode.
[0174] Among them, the target threshold can be specifically: the distance at which the user can make a call through the electronic device, such as: when making a call through the receiver of the electronic device, the target threshold can be set to: 1cm, or, 2cm, etc.; when making a call through the speaker of the electronic device, the target threshold can be set to: 20cm, or, 30cm, etc.
[0175] For example: when the distance between the user and the electronic device is a, a is greater than the target threshold. At this time, the first adjustment mode is determined, and the first magnetic field noise generated when the power amplifying component is adjusted according to the first adjustment mode is K1; when the distance between the user and the electronic device is b, b is less than the target threshold (that is, a>b), at this time, the second adjustment mode is determined, and the second magnetic field noise generated when the power amplifying component is adjusted according to the second adjustment mode is K2, where K1>K2.
[0176] In addition, after adjusting according to the first adjustment mode, the magnetic field noise felt by the user at a position where the distance between the user and the electronic device is a is reduced, and the magnetic field noise felt by the user at this position is lower than the noise requirement; after adjusting according to the second adjustment mode, the magnetic field noise felt by the user at a position where the distance between the user and the electronic device is b is also reduced, and the magnetic field noise felt by the user at this position is lower than the noise requirement. However, if the transmission power of the power amplifier is adjusted according to the first adjustment mode when the distance between the user and the electronic device is b, then after the adjustment is completed, the magnetic field noise felt by the user at a position where the distance between the user and the electronic device is b is higher than the noise requirement. Therefore, when the distance between the user and the electronic device is less than the target threshold, the second adjustment mode cannot be used to adjust the transmission power of the power amplifier, that is, when the distance between the user and the electronic device is different, different adjustment modes need to be used to adjust the transmission power of the electronic device to ensure that after the adjustment is completed, the magnetic field noise felt by the user can be lower than the noise requirement.
[0177] The distance between the user and the electronic device may specifically be the distance between the user and a target object, such as a receiver, an antenna or a target area of the electronic device.
[0178] The power regulation method disclosed in the present embodiment, when determining that the transmission power of a power amplifier in a working state needs to be adjusted, can select different regulation modes for adjustment based on the different distances between the user and the electronic device. If the distance between the user and the electronic device is greater than the target threshold, the transmission power is adjusted according to the first regulation mode. If the distance between the user and the device is less than the target threshold, the transmission power is adjusted according to the second regulation mode. The first magnetic field noise generated when the power amplifying component adjusted according to the first regulation mode works is greater than the second magnetic field noise generated when the power amplifying component adjusted according to the second regulation mode works. Therefore, on the basis of ensuring that the user is not affected by the magnetic field noise when using the electronic device, the power amplifier of the electronic device can ensure a certain transmission power to transmit data to ensure the communication effect.
