Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Electronic devices such as mobile phones and tablet computers are usually connected to a network through a WiFi network. After the electronic device performs the WiFi connection, it usually performs a transmission rate adjustment to determine a transmission rate suitable for the current data transmission.
When the electronic device adjusts the WiFi transmission rate, it generally adjusts from high to low according to the protocol requirement, if the wireless environment is good, and the transmission rate can reach the highest transmission rate required by the protocol, it may reduce the power consumption of the electronic device by reducing the transmission power; when the WiFi transmission rate is not the highest rate of the protocol, then the transmit power is not reduced.
Generally, the rate selection of the electronic device is passive and selected according to the environment, that is, generally, the wireless environment is poor, and the electronic device selects a transmission rate that meets the requirement of stably and effectively transmitting data in the current wireless environment. For example, a table using different transmission rates according to different WiFi signal strengths is customized in advance in the test, and when WiFi is in a certain environment, a transmission rate is searched against the table to start transmission. If the wireless environment is poor, it is found that transmission often fails when the current transmission rate is used, for example, the retransmission rate reaches a certain value, and the error rate reaches a certain value, the transmission rate is reduced. In the reducing process, the transmission rate which can be reduced is searched for, and the gradient reduction is carried out continuously until the suitable transmission rate is found for transmission, wherein each transmission rate corresponds to one transmitting power. Therefore, in this case, the electronic device generally selects a low transmission rate for transmission because the requirements of the current wireless environment cannot be met.
The wireless environment is an environment related to and having an influence on the WiFi connection, such as one or more of the number of access points in an environment around the electronic device, the number of access points in a channel used by the access point connected to the electronic device, a congestion index of a channel in which the access point is located, a signal-to-noise ratio of the channel in which the access point is located, a transmission power of the access point, and a signal strength of the access point, which are not limited in the embodiment of the present application.
However, the inventor finds that if the transmission rate is actively switched to low transmission rate transmission by the electronic device, rather than being forced to be adjusted to low transmission rate transmission to satisfy stable transmission of data due to the complicated wireless environment, a certain transmission power can be reduced to satisfy the requirement of reducing power consumption, and the requirement of stable transmission of data can still be satisfied. Therefore, the present application provides a method, an apparatus, and an electronic apparatus for adjusting transmit power, which determine whether to adjust the transmit power according to a determination method of a transmission rate. If the transmission rate is determined in such a manner that the electronic device is actively switched to low transmission rate for transmission, the transmission power can be adjusted, and the power consumption can be reduced.
The following describes a method, an apparatus, and an electronic apparatus for adjusting transmit power according to embodiments of the present application with reference to the accompanying drawings.
First embodiment
Referring to fig. 1, a first embodiment of the present application provides a method for adjusting transmission power, which is applied to an electronic device, where the electronic device may be a wireless device, and includes a WiFi module, and a wireless access point may be connected to the electronic device through the WiFi module, so as to access a network. The electronic device may be a mobile phone, a tablet computer, a notebook computer, a multimedia device, an intelligent wearable device, a reader, and other devices capable of WiFi connection, which is not limited in the embodiment of the present application.
In the method, whether to adjust the transmission power may be determined according to a current transmission rate determination manner. And if the current transmission rate is determined by the active selection of the electronic device, reducing the transmission power so as to reduce the power consumption. In a specific embodiment, the transmission power adjustment method is applied to the transmission power adjustment apparatus shown in fig. 3 and the electronic apparatus 400 (fig. 4 and 5) corresponding to the transmission power adjustment apparatus 300. The method for adjusting the transmission power may specifically include the following steps:
step S110: the WiFi module is connected with the wireless access point at a target transmission rate and a target transmission power.
The electronic device can be connected with the wireless access point through the WiFi module, and data transmission can be carried out at a certain transmission rate and transmission power in the connection process after the electronic device is connected with the wireless access point.
It can be understood that the target transmission rate and the target transmission power are named transmission rate and transmission power for convenience of description, and actually, the actual transmission rate of the WiFi module and the actual transmission power of the WiFi module are determined according to the transmission rate determination manner of the WiFi module when it is required to determine whether to adjust the transmission power.
Step S120: and acquiring a determination mode of the target transmission rate, wherein the determination mode comprises active selection and determination by an electronic device and passive debugging and determination according to the data transmission condition.
The electronic device obtains a determination mode of the current target transmission rate. The determination method may be actively determined by the electronic device, that is, the transmission rate is not necessarily reduced to the target transmission rate due to unstable data transmission or undesirable transmission effect caused by the wireless environment; the determination method may also be determined by passive adjustment according to the data transmission condition, that is, the electronic device has to adjust the transmission rate down to the current target transmission rate due to unstable data transmission or non-ideal transmission effect caused by the wireless environment.
Specifically, the determining manner for the electronic device to actively select and determine the target transmission rate may include: and selecting a target transmission rate from a preset corresponding relation table according to the performance index of the electronic device, wherein the corresponding relation table comprises the corresponding relation between the performance index and the transmission rate. That is, the transmission rates that may correspond to various performance indexes of the electronic device in the wireless environment are obtained through pre-testing, and a correspondence table is formed, such as factory testing. In the actual use process of the electronic device, the performance index of the electronic device can be obtained, and the transmission rate of the WiFi module is determined according to the transmission rates corresponding to different performance indexes in the corresponding relation table.
Wherein the performance index includes equipment performance or environmental parameters of the electronic device. For example, the performance indicator may be signal strength. Because different electronic devices have a certain difference, the corresponding optimal transmission rates of the different electronic devices may be different under the same signal intensity; for the same electronic device, the corresponding optimal transmission rates may be different at different signal strengths. Therefore, for each electronic device, the transmission rates at different signal strengths may be pre-tested to determine a preferred transmission rate, such as pre-factory testing. That is, in the case that the electronic device receives signals with different intensities, a data transmission test is performed on each signal intensity at different transmission rates, a transmission rate with relatively good data transmission efficiency and stability is determined, a corresponding relationship between the signal intensity and the transmission rate is formed, and the electronic device can be stored in the form of a corresponding relationship table. The transmission rate selected corresponding to each signal strength during the specific test is not limited in the embodiment of the present application, and in the corresponding relationship, one signal strength interval may correspond to the transmission rate, or one specific signal strength may correspond to the transmission rate; the corresponding transmission rate may also be a specific value or an interval value.
Of course, the performance index may be other, such as EVM value, number of surrounding access points, number of access points in the channel connected to the access point, signal-to-noise ratio of the channel connected to the access point, and so on. The EVM is an error vector, comprises an amplitude vector and a phase vector, is a vector difference between an ideal error-free reference signal and an actual transmitting signal at a given moment, and can comprehensively measure the amplitude error and the phase error of a modulation signal.
In addition, the corresponding transmission rates under various performance indexes can be tested in advance to form a corresponding relation table. The functional relationship between the performance index and the transmission rate can also be formed according to the relevance of the performance index and the transmission rate. When the method is actually used, the corresponding transmission rate is obtained according to the current performance index and the functional relation.
The transmission rate determined by the electronic device through passive debugging according to the data transmission condition can be set after the electronic device is connected with the wireless access point, but at the transmission rate, the data transmission effect is not ideal, the signal quality is poor, and the data transmission is unstable. In order to ensure the stability of data transmission, the transmission rate has to be adjusted downward, i.e. the transmission rate determined by passive adjustment according to the data transmission condition.
Specifically, the passive debugging process may include: after the electronic device is connected with the wireless access point, setting an initial transmission rate, wherein the initial transmission rate can be a default initial value; the initial transmission rate may also be the transmission rate determined by the aforementioned active selection.
And then judging whether the signal quality between the WiFi module and the wireless access point meets a second preset standard or not when the wireless access point transmits at the initial transmission rate. The signal quality may include a retransmission rate and an error rate in a data transmission process, or may include other indexes for measuring a data transmission condition, which are not listed here. And judging whether the measured data of the signal quality such as the retransmission rate or the bit error rate of the data transmission meets a preset second preset standard, wherein the second preset standard can be set before leaving the factory and stored in the electronic device, and the specific setting value is not limited in the embodiment of the application.
If the signal quality is determined not to satisfy the second predetermined criterion, it indicates that the initial transmission rate may be too high, resulting in poor signal quality, and thus the initial transmission rate may be decreased. After the initial transmission rate is reduced, the step of determining whether the signal quality between the WiFi module and the wireless access point meets a second preset criterion when transmitting at the initial transmission rate may be performed again according to the reduced initial transmission rate. That is, the initial transmission rate determined when the re-execution is performed is the initial transmission rate after the reduction. And in the process of transmitting the initial transmission rate reduced transmission rate by the WiFi module, judging whether the signal quality between the WiFi module and the wireless access point meets the second preset standard again, and if not, reducing the current transmission rate again until the signal quality meets the second preset standard. Wherein the reduction of the transmission rate may be a reduction with a preset gradient; alternatively, a correspondence table of signal quality and transmission rate may be preset, and the lower the signal quality, for example, the higher the retransmission rate and the higher the error rate, the lower the corresponding transmission rate, and the reduced transmission rate may be determined from the correspondence table.
And if the signal quality is judged to meet the second preset standard, taking the current transmission rate as the target transmission rate. That is, if the determination mode of the target transmission rate is obtained, the transmission rate of the WiFi module is the transmission rate reduced according to the signal quality determination, and the transmission rate is used as the target transmission rate determined according to the passive debugging of the data transmission condition.
Optionally, in this embodiment of the application, if, when the determination manner of the target transmission rate is obtained, the transmission rate between the WiFi module and the wireless access point is an initial transmission rate that is determined for the first time after being connected to the wireless access point and is not reduced because the signal quality does not satisfy the second preset criterion, it may be determined that the determination manner of the target transmission rate is actively selected and determined by the electronic device.
Step S130: and if the determination mode is determined by the active selection of the electronic device, reducing the target transmitting power.
After determining the transmission rate, the electronic device sets the transmission power corresponding to the transmission rate. The specific setting of the transmission power may be determined according to a preset rate and power correspondence table, where the rate and power correspondence table includes a correspondence relationship between a transmission rate and the transmission power.
If the target transmission rate is actively selected by the electronic device, the reliability of data transmission at the target transmission rate may be higher, so that the power consumption may be reduced by reducing the transmission power value, and the reduced transmission power may be used as a new transmission power of the WiFi module.
If the target transmission rate is determined according to the passive debugging of the data transmission condition, the wireless environment may be complex, the stability of the data transmission needs to be ensured, the transmission power of the wireless communication device may not be reduced, and the transmission power set according to the transmission rate is used as the current transmission power of the WiFi module.
In the embodiment of the application, whether the transmitting power is adjusted or not is judged according to the determination mode of the transmission rate. If the transmission rate is actively selected and determined by the electronic device, the transmission power corresponding to the transmission rate is reduced, and the power consumption is saved; if the transmission rate is passively debugged and determined according to the data transmission condition, the transmitting power can be kept unchanged, so that the stability of data transmission is met to the maximum extent, and the power consumption can be reduced as much as possible.
In the embodiment of the present application, a specific reduction manner of the transmission power may also be included. The method comprises the following steps:
step S210: the WiFi module is connected with the wireless access point at a target transmission rate and a target transmission power.
Step S220: and acquiring a determination mode of the target transmission rate, wherein the determination mode comprises active selection and determination by an electronic device and passive debugging and determination according to the data transmission condition.
When the electronic device is connected with the wireless access point through the WiFi module, the electronic device is wirelessly connected through a certain transmission rate and transmission power. During the wireless transmission after the connection, the transmission rate may be adjusted or may be consistent with the transmission rate at the time of establishing the connection. In this embodiment of the application, in a determination manner of obtaining the target transmission rate, a transmission rate corresponding to the WiFi module and the wireless access point is the current target transmission rate, and a transmission power corresponding to the WiFi module and the wireless access point is the current target transmission power.
The timing of determining whether to adjust the transmission power according to the determination mode of the transmission rate of the WiFi module is not limited in the embodiment of the present application, and may be that whether to adjust is determined just by establishing a connection between the WiFi module and the wireless access point; or, after a preset time length after the connection is established between the WiFi module and the wireless access point, determining whether to adjust the transmission power. In addition, whether to adjust the transmission power may also be determined at preset time periods, that is, at every preset time period, whether to adjust the transmission power may be determined once. And determining whether to adjust the transmitting power according to the determination mode of the transmission rate of the WiFi module each time, taking the transmission rate corresponding to the current connection as a target transmission rate, taking the transmitting power corresponding to the current connection as the target transmitting power, and judging whether to reduce the target transmitting power according to the determination mode of the target transmission rate.
Step S230: and if the determination mode is determined by the active selection of the electronic device, reducing the target transmitting power.
The specific manner of reducing the target transmission power is not limited in the embodiment of the present application. For example, the target transmitting power may be reduced in a gradient manner, for example, each time the target transmitting power is reduced by 0.5dBm, each time the target transmitting power is reduced, whether the target transmitting power meets the internet access index is verified, if the target transmitting power meets the internet access index, the target transmitting power may be reduced continuously, and if the target transmitting power does not meet the internet access index, the transmitting power before the target transmitting power is reduced at this time is used as the transmitting power of the WiFi module. Specifically, as shown in fig. 2, the process may be:
step S231: and reducing the target transmitting power according to a preset power gradient.
Step S232: and judging whether the signal quality between the WiFi module and the wireless access point meets a first preset standard or not after the target transmitting power is reduced. If yes, go to step S231; if not, go to step S233.
And when the step of reducing the target transmitting power according to the preset power gradient is executed again, reducing the target transmitting power which is reduced last time again.
Step S233: and taking the target transmission power before the current reduction as the transmission power of the WiFi module.
And reducing the target transmitting power by a preset power gradient, connecting the transmitting power obtained after the target transmitting power is reduced with the wireless access point, and judging whether the signal quality between the wireless access point and the target transmitting power in the connection process meets a first preset standard so as to judge whether the signal quality meets the internet access index. If the signal quality between the WiFi module and the wireless access point meets the first preset standard, it may be considered that the transmission power is reduced again, and in the connection process of the reduced transmission power, whether the signal quality between the WiFi module and the wireless access point meets the first preset standard or not may be considered. And continuously reducing the gradient until the reduced signal quality between the WiFi module and the wireless access point does not meet the transmission power of the first preset standard, and taking the transmission power before the reduction of the transmission power as the transmission power for finally reducing the connection between the determined WiFi module and the wireless access point.
For example, when the determination mode is determined by active selection of the electronic device, the target transmitting power is 15dBm, and the preset power gradient is 0.5 dBm. When the transmitting power is reduced to 14.5dBm, judging whether the signal quality between the WiFi module and the wireless access point meets a first preset standard or not; if yes, reducing 14.5dBm by 0.5dBm to obtain 14dBm, and judging whether the signal quality meets a first preset standard or not when the WiFi module is connected with the wireless access point by the transmitting power of 14 dBm; if the signal quality corresponding to 14dBm meets the first preset standard, then reducing the 14dBm by 0.5dBm to obtain 13.5dBm, judging whether the signal quality meets the first preset standard when the WiFi module is connected with the wireless access point with the transmitting power of 13.5dBm, and if the signal quality corresponding to 14dBm does not meet the first preset standard, determining that the WiFi module is connected with the wireless access point with the transmitting power of 14.5 dBm.
Optionally, in the embodiment of the present application, the gradient of the decrease in the transmission power may not be a fixed and unchangeable value.
For example, the values may be sequentially decreased, when the transmission power is decreased, the maximum preset power gradient may be used for the previous time or the previous times, and if the transmission power is continuously decreased, the smaller power gradient may be sequentially used. If the preset power gradient reduction is respectively 0.5dBm, 0.4dBm, 0.3dBm and 0.2dBm, and the target transmitting power is 15dBm, whether the signal quality meets a first preset standard or not can be judged after 0.5dBm is reduced; if yes, continuing to reduce 14.5dBm by 0.4dBm, and judging whether the signal quality meets the first preset standard or not until the signal quality does not meet the first preset standard.
For another example, the preset power gradient may be a sequentially decreasing value. In the reducing process, after the transmitting power is reduced by the maximum preset power gradient, if the signal quality between the WiFi module and the wireless access point meets the first preset standard, the transmitting power is continuously reduced by the maximum preset power gradient. If the transmission power is reduced by the maximum preset power gradient, the signal quality does not meet the first preset standard, the transmission power is reduced by the next largest preset power gradient again, whether the signal quality meets the first preset standard or not is judged again, and if the signal quality meets the first preset standard, the reduced transmission power is used as the finally obtained transmission power of the WiFi module; if the signal quality does not meet the first preset standard, the transmitting power is reduced again by a smaller preset power gradient until the transmitting power corresponding to the signal quality meeting the first preset standard is obtained, or the transmitting power is not reduced any more until the signal quality meets the first preset standard after the transmitting power is reduced by the minimum preset power gradient.
For example, the predetermined power gradient decreases to 0.5dBm, 0.4dBm, 0.3dBm, and 0.2dBm, respectively, and the target launch power is 15.5dBm, 15.5dBm may be reduced by 0.5dBm first to obtain 15 dBm. Judging whether the signal quality meets a first preset standard when the transmitting power is 15 dBm; if yes, further decrease 15dBm by 0.5dBm to obtain 14.5 dBm.
Judging whether the signal quality meets a first preset standard when the transmitting power is 14.5 dBm; if yes, then reducing 14.5dBm by 0.5dBm, if not, reducing 15dBm by 0.4dBm to obtain 14.6dBm, and judging whether the signal quality meets the first preset standard when the emission power is 14.6 dBm. If the signal quality meets a first preset standard when the transmitting power is 14.6dBm, taking 14.6dBm as the finally determined transmitting power of the WiFi module; if the signal quality does not meet the first preset standard when the transmitting power is 14.6dBm, reducing the signal quality by 0.3dBm by 15dBm to obtain 14.7dBm, and judging whether the signal quality meets the first preset standard when the transmitting power is 14.7 dBm. If the signal quality meets a first preset standard when the transmitting power is 14.7dBm, taking 14.7dBm as the finally determined transmitting power of the WiFi module; if the signal quality does not meet the first preset standard when the transmitting power is 14.7dBm, reducing the signal quality by 0.2dBm by 15dBm to obtain 14.8dBm, and judging whether the signal quality meets the first preset standard when the transmitting power is 14.8 dBm. If the signal quality meets a first preset standard when the transmitting power is 14.8dBm, taking 14.8dBm as the finally determined transmitting power of the WiFi module; and if the signal quality does not meet the first preset standard when the transmitting power is 14.8dBm, still taking 15dBm as the finally determined transmitting power of the WiFi module. Therefore, the transmitting power can be reduced only rapidly, and the phenomenon that the transmitting power is not reduced as much as possible due to overlarge preset power gradient can be avoided.
Certainly, the specific value of the preset power gradient is not limited in the embodiment of the present application, the foregoing description is only a distance, and a value meeting the WIFI protocol index may be set according to an actual situation during specific setting.
Optionally, in this embodiment of the present application, the reduction of the transmission power may also be in other forms, for example, different transmission powers or reduction gradients corresponding to transmission power intervals may be preset, and when the reduction is performed, the corresponding reduction gradient is searched according to the current transmission power, and after the transmission power is reduced by the gradient, whether the signal quality meets the first preset criterion is determined.
The signal quality may be a retransmission rate, an error rate, and the like during data transmission. The specific standard value of the first preset standard is not limited in the embodiment of the present application.
Alternatively, if the determination mode of the target transmission rate is actively selected and determined by the electronic device, a shorter preset time period may be set. And if the determination mode of the transmission rate is actively selected and determined by the electronic device, after the steps are executed, the steps are executed again according to a preset time period, and whether the transmission power is reduced or not is judged by the determination mode of the target transmission rate. If the determination manner of the target transmission rate is determined by passive debugging according to the data transmission condition, the above steps may not be periodically performed, that is, it is not determined whether to reduce the power by the determination manner of the transmission rate.
In the embodiment of the application, the transmission power gradient is reduced under the condition that the target transmission rate is actively selected and determined for the electronic device, and the transmission power with lower energy consumption is obtained. If the target transmission rate is passively debugged and determined according to the data transmission condition, the transmitting power is not adjusted any more, so that the stability of data transmission in a complex wireless environment is ensured as much as possible, and a good transmission effect is obtained.
As shown in fig. 3, an embodiment of the present application further provides a transmission power adjustment apparatus 300, which is applied to an electronic apparatus, where the electronic apparatus includes a WiFi module. The apparatus 300 comprises: a connection module 310, configured to connect the WiFi module and the wireless access point at a target transmission rate and a target transmission power.
