Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The application discloses a processing method, the flow chart of which is shown in figure 1, comprising the following steps:
step S11, responding to the target voltage configuration of the power amplifier as a first voltage value, and obtaining a target parameter;
And step S12, if the target parameter is greater than or equal to the standard value, configuring the target voltage as a second voltage value, wherein the second voltage value is smaller than the first voltage value, and the target parameter is used for representing the influence of a target channel of the power amplifier in a target frequency band on a channel except the target channel.
In APT (enhanced APT) enhanced average power tracking scenario or EPT (Auto Power Tracking) average power tracking scenario, when the antenna of the electronic device is operating, such as: the communication is established through the electronic equipment, or the internet surfing and the like is realized, at the moment, the radio frequency transceiver transmits or receives radio frequency signals, and when the radio frequency transceiver transmits the radio frequency signals, the radio frequency signals transmitted by the radio frequency transceiver are amplified by the power amplifier, filtered by the filter and then transmitted through the antenna.
In practical use, if the transmit power of the power amplifier is set smaller, the call quality will be affected, or the network connection speed will be increased, so that the transmit power of the power amplifier is generally set larger in order to ensure normal operation of the call, or normal use of the network, which will result in larger power consumption of the power amplifier.
In the scheme, the target voltage of the power amplifier is configured, and the target parameter is obtained based on the first voltage value configured for the target voltage, so that the power amplifier works through the first voltage value based on the current channel, the target voltage of the power amplifier is adjusted based on the comparison result of the target parameter and the standard value, and when the target voltage of the power amplifier is reduced based on the target parameter, the power consumption of the power amplifier is reduced, so that the purpose of reducing the power consumption of the power amplifier is achieved.
When an antenna in the electronic equipment works, the radio frequency transceiver sends out signals, and the power amplifier is used for amplifying the signals sent out by the radio frequency transceiver so as to be conveniently output through the antenna. When the power amplifier works, the target voltage needs to be configured for the power amplifier, the difference of the target voltage can lead to the difference of the strength of signals sent by the antenna, so that the communication efficiency is affected, and meanwhile, the difference of the target voltage can also lead to the difference of comparison results of the target parameter and the standard value, so that the target voltage can be adjusted based on the comparison results of the target parameter and the standard value, and the power consumption of the power amplifier can be adjusted.
In the communication process of the electronic equipment, whether telephone communication or network connection is carried out, the electronic equipment works in a certain frequency band, a certain channel is corresponding to the frequency band, and signal transmission, namely a target channel, is carried out through the channel. In the process of signal transmission through the target channel, if the power of the power amplifier is leaked from the adjacent channel when the target channel works, the normal signal transmission of the adjacent channel of the target channel can be influenced.
The target parameter is adjacent channel power leakage ratio ACLR, which is the ratio of the power leaked in the adjacent channel to the power of the target channel. The larger the absolute value of the adjacent channel leakage ratio should be. The larger the value, the more the main channel power is larger than the power leaked in the adjacent channel, and the smaller the influence on the adjacent channel is. For example, the adjacent channel power leakage ratio ACLR may be 32.2dBc under 3GPP specifications, and in this scheme, the adjacent channel power leakage ratio is compared with a standard value, and if the adjacent channel power leakage ratio is greater than the standard value, the greater the main channel power is compared with the power leaked in the adjacent channel, the smaller the influence on the adjacent channel is, and the greater the adjustable range of the target voltage of the power amplifier is, the more power consumption of the power consumption can be saved.
Therefore, after obtaining the adjacent channel power leakage ratio of the power amplifier based on the current target voltage, the adjacent channel power leakage ratio at the current target voltage is compared with a standard value, thereby determining whether the target voltage of the power amplifier can be adjusted currently.
The standard value is the standard value that the adjacent channel power leakage ratio should satisfy when the antenna of the electronic device works normally, for example: in the 3GPP scenario, the standard value may be 32.2dBc.
If the adjacent channel power leakage ratio of the power amplifier based on the current target voltage is larger than the standard value, the current target voltage of the power amplifier can be adjusted, and the power consumption of the power amplifier is adjusted by adjusting the target voltage of the power amplifier. Therefore, under the condition that the antenna transmits parameters such as quality, strength and the like of signals based on a target channel of a target frequency band, the influence of an adjacent channel is effectively ensured to be within (or not influenced by) an index range specified by 3GPP, and the power consumption of the power amplifier can be effectively reduced.
If the power leakage ratio of the adjacent channel of the power amplifier is greater than or equal to the standard value when the target voltage of the power amplifier is configured to be a first voltage value, the voltage of the power amplifier needs to be reduced, and the target voltage of the power amplifier is configured to be a second voltage value, wherein the second voltage value is smaller than the first voltage value.
After the target voltage of the power amplifier is reduced from the first voltage value to the second voltage value, the adjacent channel power leakage ratio is changed. And determining whether the target voltage of the power amplifier needs to be continuously regulated or not based on the comparison result of the adjacent channel power leakage ratio and the standard value.
In addition, it should be noted that the target parameter may be a neighbor channel power leakage ratio, or may be other values, such as: the power value of the target channel leaked to the adjacent channel, or the power value of the target channel, the power value of the adjacent channel, etc.
In the processing method disclosed by the embodiment, a target parameter is obtained in response to the target voltage of the power amplifier being configured as a first voltage value; if the target parameter is greater than or equal to the standard value, the matched target voltage is a second voltage value, and the second voltage value is smaller than the first voltage value; the target parameters are used for representing the influence of a target channel of the power amplifier in a target frequency band on channels other than the target channel. According to the scheme, the target voltage of the power amplifier is adjusted through the comparison result of the target parameter and the standard value, so that the power consumption of the power amplifier is adjusted, when the power amplifier works in a target channel, if the target parameter is greater than or equal to the standard value, the target voltage needs to be reduced, the power consumption of the power amplifier is reduced, and the purpose of energy conservation is achieved.
The embodiment discloses a processing method, a flow chart of which is shown in fig. 2, comprising:
step S21, responding to the target voltage configuration of the power amplifier as a first voltage value, and obtaining a target parameter;
s22, if the target parameter is greater than or equal to a standard value, configuring a target voltage as a second voltage value, wherein the second voltage value is smaller than the first voltage value, and the target parameter is used for representing the influence of a target channel of the power amplifier in a target frequency band on a channel except the target channel;
step S23, if the target parameter is smaller than the standard value, configuring the target voltage as a third voltage value, wherein the third voltage value comprises one of the following components: a second voltage value and a first voltage value.
And adjusting the target voltage based on the comparison result of the target parameter and the standard value, namely adjusting the target voltage based on the comparison result of the adjacent channel power leakage ratio of the power amplifier under the current target voltage and the standard value.
If the adjacent channel power leakage ratio of the power amplifier based on the current target voltage is larger than the standard value, the target voltage of the power amplifier is indicated to have an adjustable allowance, and the target voltage can be reduced so as to achieve the purpose of reducing power consumption;
if the adjacent channel power leakage ratio of the power amplifier based on the current target voltage is equal to the standard value, the target voltage of the power amplifier can not be regulated at the moment, and the target voltage of the power amplifier can be reduced, so that the purpose of reducing the power consumption of the power amplifier is achieved;
If the adjacent channel power leakage ratio of the power amplifier based on the current target voltage is smaller than the standard value, the target voltage of the power amplifier is smaller, and at this time, the voltage of the power amplifier needs to be regulated up, and the power consumption of the power amplifier increases based on the increase of the target voltage of the power amplifier.
Such as: when the antenna is in a working state, a signal sent by the radio frequency transceiver is amplified by the power amplifier, if the target voltage of the power amplifier is a first voltage value, the obtained adjacent channel power leakage ratio is smaller than a standard value, the first voltage value can be determined to be smaller, at the moment, the problem that the signal transmission effect cannot meet the requirement possibly exists, and the influence of the target channel on the adjacent channel is small; such as: if the electronic device is currently in a call, a problem of poor signal during the call may occur, for example: intermittent conversation, or incapability of hearing, etc.
Only when the adjacent channel power leakage ratio is not smaller than the standard value, the condition that the signal transmission effect does not meet the requirement can be avoided. Therefore, when it is determined that the adjacent channel power leakage ratio is smaller than the standard value, it is necessary to increase the target voltage of the power amplifier.
It should be noted that, in the working process of the antenna, no matter whether the target parameter is detected, that is, the adjacent channel power leakage ratio is greater than, equal to or smaller than the standard value, the target voltage of the power amplifier can be adjusted, and after adjustment, the comparison result of the adjacent channel power leakage ratio of the current power amplifier and the standard value is continuously monitored, so that the power amplifier after adjustment can be in lower power consumption under the condition of ensuring that the communication requirement is met.
Specifically, if the current adjacent channel power leakage ratio is determined to be smaller than the standard value when the target voltage of the power amplifier is configured as the first voltage value, directly adjusting the target voltage to enable the adjusted target voltage to be a third voltage value larger than the first voltage value, continuously determining the adjacent channel power leakage ratio based on the current voltage value at the moment, and comparing the adjacent channel power leakage ratio with the standard value; if the adjacent channel power leakage ratio is still smaller than the standard value, the target voltage needs to be continuously increased until the adjacent channel power leakage ratio based on the target voltage is determined to be larger than or equal to the standard value, and the power amplifier is kept working based on the current target voltage.
If the current adjacent channel power leakage ratio is determined to be equal to the standard value when the target voltage of the power amplifier is configured to be the first voltage value, the target voltage of the power amplifier can not be regulated at the moment, so that the power amplifier can keep working continuously with the current target voltage; the target voltage can be reduced to a second voltage value based on the current adjacent channel power leakage ratio equal to the standard value, even if the target voltage is smaller than the first voltage value, whether the adjacent channel power leakage ratio obtained after the target voltage of the power amplifier is reduced can still be not smaller than the standard value is determined, if the adjacent channel power leakage ratio is determined to be smaller than the standard value at the moment, the target voltage can be increased, so that the target voltage still maintains the first voltage value, namely the adjacent channel power leakage ratio is ensured to be equal to the standard value, and then the target voltage is not regulated; if the determined adjacent channel power leakage ratio is still not less than the standard value, the target voltage may be continuously reduced so that the reduced target voltage is less than the second voltage value, then whether the current adjacent channel power leakage ratio is less than the standard value is continuously determined, and if it is determined that the current adjacent channel power leakage ratio is less than the standard value, the target voltage needs to be increased, for example: at this time, the target voltage may be increased to the first voltage value, or may be increased only to the second voltage value, and then the adjustment is not performed, that is, the target voltage cannot be continuously reduced on the basis of ensuring that the adjacent channel power leakage ratio is greater than or equal to the standard value.
Similarly, if it is determined that the current adjacent channel power leakage ratio is greater than the standard value when the target voltage of the power amplifier is configured as the first voltage, the target voltage is reduced, and the specific manner is similar to the adjustment process when the adjacent channel power leakage ratio is equal to the standard value, which is not described herein.
It should be noted that, a configuration table may be preset, where the configuration table is used to record configuration parameters of different levels of the power amplifier, where the configuration parameters at least include a target voltage, and may further include: dc bias ICQ, radio frequency gain RGI, etc.
Therefore, when the target voltage of the power amplifier is adjusted based on the comparison result of the adjacent channel power leakage ratio and the standard value, the adjustment can be directly based on the configuration table, such as: the target voltage configured for the power amplifier in advance is a first voltage value, which is in a third-level configuration parameter in the configuration table, and if it is determined that the current adjacent channel power leakage ratio is greater than or equal to the standard value, the target voltage can be reduced, that is, a second voltage value smaller than the first voltage value in the configuration table is selected, where the second voltage value can be a voltage value adjacent to the first voltage value in the configuration table, such as: the voltage value in the fourth level configuration parameter may also be a voltage value not adjacent to the fourth level configuration parameter, for example: voltage values in the fifth level configuration parameters; if it is determined that the current adjacent channel power leakage ratio is smaller than the standard value, the target voltage may be increased, that is, a voltage value larger than the first voltage value in the configuration table is selected, where the voltage value may be a voltage value adjacent to the first voltage value in the configuration table, for example: the voltage value in the second level configuration parameter may also be a voltage value not adjacent thereto, such as: voltage values in the first level configuration parameters.
The first voltage value initially configured for the power amplifier may be equal to a certain voltage value in the configuration table, or may be unequal to any voltage value in the configuration table, and may be adjusted directly based on a voltage value greater than or less than the first voltage value during adjustment.
Of course, when adjusting the target voltage of the power amplifier based on the comparison result of the adjacent channel power leakage ratio with the standard value, the adjusting in synchronization may further include: dc bias ICQ and/or radio frequency gain RGI, etc.
In the processing method disclosed by the embodiment, a target parameter is obtained in response to the target voltage of the power amplifier being configured as a first voltage value; if the target parameter is greater than or equal to the standard value, the matched target voltage is a second voltage value, and the second voltage value is smaller than the first voltage value; the target parameters are used for representing the influence of a target channel of the power amplifier in a target frequency band on channels other than the target channel. According to the scheme, the target voltage of the power amplifier is adjusted through the comparison result of the target parameter and the standard value, so that the power consumption of the power amplifier is adjusted, when the power amplifier works in a target channel, if the target parameter is greater than or equal to the standard value, the target voltage needs to be reduced, the power consumption of the power amplifier is reduced, and the purpose of energy conservation is achieved.
The embodiment discloses a processing method, a flow chart of which is shown in fig. 3, comprising:
step S31, responding to the target voltage configuration of the power amplifier as a first voltage value, and obtaining a first response value of a target channel;
step S32, obtaining a second response value of a first channel adjacent to the target channel;
step S33, determining a target parameter based on the first response value and the second response value;
and step S34, if the target parameter is greater than or equal to the standard value, configuring the target voltage as a second voltage value, wherein the second voltage value is smaller than the first voltage value, and the target parameter is used for representing the influence of a target channel of the power amplifier in a target frequency band on a channel other than the target channel.
The target parameter is used for characterizing the influence of a target channel of the power amplifier in a target frequency band on a channel other than the target channel, and the influence can be an adjacent channel power leakage ratio, namely the ratio of the power leaked to other channels by the power amplifier when the current target voltage is in the target channel operation to the power of the target channel.
Therefore, to determine the target parameter, it is necessary to determine not only the value of the power amplifier on the target channel based on the current target voltage, but also the value of the leakage of the power amplifier to other channels when the power amplifier operates based on the current target voltage.
Namely: a first response value of the target channel is obtained, a second response value of a first channel adjacent to the target channel is obtained, and a target parameter is determined based on the first response value and the second response value.
The response value may be a power value, where the first response value is a power value of the target channel, and the second response value is a power value of an adjacent channel of the target channel.
When the antenna works, a target voltage is configured for the power amplifier, a first power value of the power amplifier working on a target channel is determined based on the current target voltage, a second power value of an adjacent channel of the target channel is determined, and a target parameter, namely the adjacent channel power leakage ratio, can be obtained based on the first power value and the second power value.
In the working state of the antenna, the antenna has one working frequency band, and different channels corresponding to different working frequency bands are used for transmitting signals through the channels; the power amplifier works, the target voltage is needed to supply power to the power amplifier, and the difference of the target voltages can lead to the difference of adjacent channel power leakage ratios. In addition, when the antennas operate in the same frequency band and different target voltages are configured for the power amplifiers, the adjacent channel power leakage ratio of the power amplifiers is also different.
The response value may be a current value, that is, a current value of the target channel is obtained, a current value of the first channel adjacent to the target channel is obtained, and the target parameter is determined based on the current value of the target channel and the current value of the first channel.
In addition, the response value may be an adjacent channel power leakage ratio, then the adjacent channel power leakage ratio of the target channel is obtained, the adjacent channel power leakage ratio of the first channel adjacent to the target channel is obtained, and the target parameter is determined based on the adjacent channel power leakage ratios of the two channels, where the target parameter may be a ratio of the two adjacent channel power leakage ratios, or a difference value, or may be other values, so as to achieve the purpose of adjusting the power of the power amplifier of the current channel based on the adjacent channel power leakage ratio.
In the processing method disclosed by the embodiment, in response to the configuration of the target voltage of the power amplifier as a first voltage value, a first response value of a target channel is obtained, a second response value of a first channel adjacent to the target channel is obtained, and a target parameter is determined based on the first response value and the second response value; if the target parameter is greater than or equal to the standard value, the matched target voltage is a second voltage value, and the second voltage value is smaller than the first voltage value; the target parameters are used for representing the influence of a target channel of the power amplifier in a target frequency band on channels other than the target channel. According to the scheme, the target voltage of the power amplifier is adjusted through the comparison result of the target parameter and the standard value, so that the power consumption of the power amplifier is adjusted, when the power amplifier works in a target channel, if the target parameter is greater than or equal to the standard value, the target voltage needs to be reduced, the power consumption of the power amplifier is reduced, and the purpose of energy conservation is achieved.
The embodiment discloses a processing method, a flow chart of which is shown in fig. 4a, comprising:
step S41, responding to the target voltage of the power amplifier to be configured as a first voltage value, and obtaining a first response value of a target channel through a power detector connected with the power amplifier;
step S42, obtaining a second response value of a first channel adjacent to the target channel through a power detector connected with the power amplifier;
step S43, determining a target parameter based on the first response value and the second response value;
step S44, if the target parameter is used for characterizing the influence of the target channel of the power amplifier in the target frequency band on the channel except the target channel.
When the antenna works, the radio frequency transceiver transmits radio frequency signals, the radio frequency signals are amplified by the power amplifier and then transmitted out through the antenna, and in the process, in order to determine target parameters, a power detector can be added to detect response values.
The power detector is connected with the power amplifier, can detect the response value of a target channel where the power amplifier is located in the working state of the antenna, can also detect the response values of other channels, and determines target parameters based on the response value of the target channel and the response value of the first channel after the response value of the target channel and the response value of the first channel are obtained through the power detector.
When the power detector detects the response value of the target channel, the power amplifier works in the target channel, and the detection path of the power detector is also in the target channel, so that the power detector can detect the response value of the target channel; when the power detector detects the response value of the first channel, the power amplifier still works in the target channel, the working state of the power amplifier is not adjusted, the detection path of the power detector is adjusted to the first channel, at the moment, the power detector can detect the response value of the first channel when the power amplifier works in the target channel, the process does not influence the working of the power amplifier, and the antenna can still transmit radio-frequency signals through the target channel.
When the power detector detects the response value of the first channel, the first channel may or may not transmit a signal at this time, but may be affected by the target channel, so that even if the first channel does not operate when detecting the response value of the first channel, the first channel can detect the corresponding response value due to the influence of the target channel.
The power detector may specifically be: and one end of the coupler is connected with the output end of the power amplifier, and the other end of the coupler is connected with the input end of the radio frequency transceiver.
A schematic diagram of the signal output path including the power detector is shown in fig. 5, including: a radio frequency transceiver 51, a power amplifier 52, an antenna 53 and a coupler 54. Of course, other devices may be included in the signal output path, such as: filters, switches, etc., are not described in detail herein.
After the power amplifier amplifies the radio frequency signal sent by the radio frequency transceiver, the coupler can couple a signal with a fixed proportion in the process of sending the signal through the antenna and feed the signal back to the radio frequency transceiver, and the radio frequency transceiver can determine a response value corresponding to a target channel of the current working of the power amplifier based on the signal coupled by the coupler;
if the response value of the adjacent channel is to be detected, the receiving frequency of the radio frequency transceiver can be adjusted to match the receiving frequency of the radio frequency transceiver with the adjacent channel, and at this time, the radio frequency transceiver can determine the response value of the adjacent channel based on the signal coupled by the coupler.
The response value may specifically be: the power gain value and the in-phase and quadrature components may be used to determine the power value of the power amplifier based on the detected power gain value and in-phase and quadrature components for a channel, in combination with the frequency of the channel.
Specific: a first power value corresponding to the first response value is determined based on a predetermined power frequency correspondence table, a second power value corresponding to the second response value is determined based on the predetermined power frequency correspondence table, and a target parameter is determined based on a ratio of the second power value to the first power value.
The power frequency correspondence table records power values corresponding to different response values under the same or different frequencies, as shown in fig. 4 b.
For example: the working frequency of the target channel is 2535MHz, at this time, a part of signals are coupled to the radio frequency transceiver through the coupler, and the first response value detected by the radio frequency transceiver is as follows: the gain state is 5, the gain value gain is 3875, the in-phase component I is 191, and the quadrature component Q is-895, so that the current power of the power amplifier can be determined to be 13.32dBm by inquiring the power frequency comparison table;
another example is: the working frequency of the target channel is 2535MHz, at this time, a part of signals are coupled to the radio frequency transceiver through the coupler, and the first response value detected by the radio frequency transceiver is as follows: if the gain state gain is 5, the gain value gain is 3745, the in-phase component I is 181, and the quadrature component Q is-875, then by querying the power frequency comparison table, it can be determined that the power frequency comparison table does not have data identical to the current operating state, then the frequency power data closest to the response value can be determined from the power frequency comparison table, and the current power value of the power amplifier can be determined based on the closest power value, for example: 12.2dBm.
Wherein FBRx is a radio frequency transceiver.
Based on this, when the antenna is in the working state, it is necessary to first determine the frequency value of the power amplifier when the current target channel is working, and, because different channels correspond to different frequency bands, the frequency band of the adjacent channel is different from the frequency band of the target channel, it is also necessary to determine the frequency value of the first channel adjacent to the current channel, determine the power value of the power amplifier in the current channel and the power value of the adjacent channel based on the frequency values of the target channel and the first channel, and the response values of the target channel and the first channel, and further determine the target parameter of the power amplifier based on the current target voltage, that is, the adjacent channel power leakage ratio, according to the power value of the power amplifier in the current channel and the power value of the adjacent channel, so as to adjust the target voltage, thereby achieving the purpose of reducing the power consumption of the power amplifier.
Further, the number of adjacent channels of the target channel may be plural, and then:
obtaining a three response value of each first channel adjacent to the target channel through a power detector connected with the power amplifier; a second response value is determined based on the third response values of the plurality of first channels as the response value of the first channel adjacent to the target channel.
There may be 1 or more adjacent channels of the target channel, for example: the electronic equipment performs communication on only 2 channels, the number of adjacent channels of the target channel is only 1, and if the target channel is channel 1, the adjacent channels are channel 2;
if the electronic device communicates with multiple channels, there may be 1, 2, or multiple adjacent channels of the target channel, for example: the target channel is channel 1, and the adjacent channels can only comprise adjacent channel 2, or can also comprise adjacent channel 2 and adjacent channel 3; alternatively, if the target channel is channel 3, the adjacent channels may be channel 2 and channel 4 adjacent thereto, or may be: channel 2 and channel 4 adjacent to channel 3, and channel 1 adjacent to channel 2 and channel 5 adjacent to channel 4.
Wherein it is determined whether the adjacent channel of the target channel includes only the channel immediately adjacent to the target channel or includes both the channel immediately adjacent to the target channel and the channel immediately adjacent thereto, in relation to the preset setting.
If there are multiple adjacent channels of the target channel, the second response values of the adjacent channels of the target channel need to be determined, then the frequencies of all the adjacent channels of the target channel need to be determined first, and then the receiving frequencies of the radio frequency transceiver are switched based on the frequencies of each adjacent channel, so as to determine the response value of each adjacent channel based on the structure shown in fig. 5, to obtain multiple third response values, where each third response value represents the response value of each adjacent channel, and then there are multiple adjacent channels, and there are multiple third response values.
After determining the third response value of each adjacent channel, determining a second response value based on all the third response values, and taking the second response value as the response value of the first channel adjacent to the target channel, wherein the first channel is the generic term of all the adjacent channels of the target channel.
Determining a second response value based on all the third response values may be: adding and summing the third response values of all adjacent channels, then averaging, and taking the obtained average value as a second response value; of course, the second response value may be obtained by other means, such as: a second response value is determined by the variance.
