In order to solve the problem, an embodiment of the present application provides an electronic device, please refer to fig. 1, and fig. 1 is a schematic structural diagram of the electronic device provided in the embodiment of the present application. The electronic device 100 may be a smart phone, tablet, notebook, desktop, palm top (PDA, personal Digital Assistant), or the like.

It is understood that the display 110 may include a display surface and a non-display surface opposite the display surface. The display surface is the surface of the display 110 facing the user, i.e. the surface of the display 110 visible to the user on the electronic device 100. The non-display surface is the surface of the display 110 facing the interior of the electronic device 100. The display surface is used for displaying information, and the non-display surface is not used for displaying information.
It will be appreciated that a cover plate may be further disposed on the display 110 to protect the display 110 from scratches or water damage. The cover plate may be a transparent glass cover plate, so that a user can observe the content displayed on the display screen 110 through the cover plate. It will be appreciated that the cover plate may be a sapphire glass cover plate.
The housing 120 is used to form the exterior profile of the electronic device 100 so as to house the electronics, functional components, etc. of the electronic device 100 while providing a seal and protection for the electronics and functional components inside the electronic device. For example, functional components such as a camera, a circuit board, a vibration motor, etc. of the electronic device 100 may be disposed inside the housing 120. It is understood that the housing 120 may include a center and a rear cover.
The middle frame may have a thin plate-like or sheet-like structure, or may have a hollow frame structure. The center frame may be used to provide support for the electronics or functional components in the electronic device 100 to mount the electronics, functional components of the electronic device 100 together. For example, the center may be provided with grooves, protrusions, etc. to facilitate mounting of the electronic devices or functional components of the electronic apparatus 100. It is understood that the material of the middle frame may include metal or plastic.
Wherein, the back lid can be connected with the center. For example, the rear cover may be attached to the center frame by an adhesive such as double-sided tape to effect connection with the center frame. The rear cover may be used to seal the electronic components and functional components of the electronic device 100 inside the electronic device 100 together with the middle frame and the display screen 110, so as to protect the electronic components and functional components of the electronic device 100. It will be appreciated that the battery cover may be integrally formed. In the forming process of the rear cover, a camera mounting hole and other structures of the rear camera can be formed on the rear cover. It will be appreciated that the material of the rear cover may also comprise metal or plastic, etc.
The circuit board 130 may be disposed inside the housing 120. For example, the circuit board 130 may be mounted on a center frame of the case 120 to be fixed, and the circuit board 130 is sealed inside the electronic device by a battery cover. Specifically, the circuit board 130 may be mounted on one side of the carrier board, and the display screen 110 is mounted on the other side of the carrier board. The circuit board 130 may be a motherboard of the electronic device 100. One or more of the functional components of the processor, camera, earphone interface, acceleration sensor, gyroscope, motor, detector, power amplifier, etc. may also be integrated on the circuit board 130. Meanwhile, the display screen 110 may be electrically connected to the circuit board 130 to control display of the display screen 110 by a processor on the circuit board 130.
Wherein the battery 140 may be disposed inside the housing 120. For example, the battery 140 may be mounted on a center frame of the case 120 to be fixed, and the battery 140 is sealed inside the electronic device 100 by a battery cover. Meanwhile, the battery 140 may be electrically connected to the circuit board 130 to enable the battery 140 to supply power to the electronic device 100. Wherein the circuit board 130 may be provided with a power management circuit thereon. The power management circuit is used to distribute the voltage provided by the battery 140 to the various electronic devices in the electronic device 100.
Referring to fig. 2, fig. 2 is a first block diagram of an electronic device according to an embodiment of the present application. The electronic device 100 may also include a detector 150, a power amplifier 160, and the like. Wherein the detector 150 and the power amplifier 160 may be integrated on the circuit board 130.
It should be noted that, under the condition of weak signal, the wireless local area network and the access point will negotiate the transmission mode and transmission rate of data transmission by themselves, and when ensuring that the signal-to-noise ratio satisfies the demodulation threshold to reduce the error rate, it negotiates to a higher rate as much as possible to ensure the data transmission rate. Where the signal-to-noise ratio refers to the ratio of signal to noise in an electronic device or electronic system, a signal cannot separate the useful signal from noise if the signal-to-noise ratio is too low, and only when the signal-to-noise ratio reaches a certain value, the signal-to-noise ratio is separated, i.e. the demodulation threshold. The error rate is a measure of the accuracy of data transmission over a specified period of time.
Wherein the electronic device 100 has a plurality of transmission modes for transmitting data, the wireless local area network may be generated by a wireless router, an electronic device, or the like. The multiple transmission modes of the electronic device 100 may include 11b, 11a/g, 11n, 11ac, 11ax, etc., which are mainstream protocol standards that the electronic device may support, i.e., the electronic device and the access point may negotiate the multiple transmission modes by themselves, the multiple transmission modes may be determined by hardware or software settings in the electronic device, each new standard protocol may increase the original data transmission rate, and after five generations of development from 11b, 11a/g, 11n, 11ac, 11ax, the data rate increases from 11Mb/s to 9.6Gb/s. The focus of the user using the wireless lan is on the transmission rate of the signal and the coverage area of the signal, so the user can select an applicable transmission mode according to different environments.
In addition, each transmission mode of the electronic device 100 may have multiple transmission rates. For example, when the electronic device 100 is in the 11ax transmission mode, the 11ax transmission mode may include multiple transmission rates of MCS0, MCS1, MCS2, MCS3, MCS4, MCS5, MCS6, MCS7, MCS8, MCS9, MCS10 and MCS11, and it can be seen that the maximum transmission rate in the 11ax transmission mode is 11ax MCS11, and if the electronic device is in the weak signal condition at this time, the transmission rates may be MCS0, MCS1, MCS2 and MCS3, and so on, and when the signal reaches a certain strength, the transmission rate negotiates to the maximum transmission rate MCS11 of the 11ax transmission mode. For another example, when the electronic device 100 is in the 11n transmission mode, the 11n transmission mode may include multiple transmission rates of MCS0, MCS1, MCS2, MCS3, MCS4, MCS5, MCS6, and MCS7, i.e., the maximum transmission rate in the 11n transmission mode is 11n MCS7. The MCS (Modulation and Coding Scheme, modulation and coding strategy) may implement rate configuration in the wireless lan, for example, 11ax transmission rate configuration is implemented by using a modulation index value of the MCS, and for different bandwidths of the wireless lan, MCS modulation corresponds to different transmission rates. For example, the transmission rate of MCS0 can be 6.5Mb/s for 20MHz bandwidth, and the transmission rate of MCS0 can be 13.5Mb/s for 40MHz bandwidth. Thus, the manner in which embodiments of the present application are implemented is based on the same bandwidth.
Wherein the detector 150 may detect a target transmission rate in a current transmission mode of the electronic device 100. The target transmission rate detected by the detector 150 is the maximum transmission rate in the current mode. For example, the target transmission rate detected by the detector 150 in the 11ax transmission mode is 11ax mcs11; the target transmission rate detected by the detector 150 in the 11n transmission mode is 11n MCS7.
It should be noted that, with the development of the technology, the MCS modulation mode is more and more complex, and in order to ensure that the vector error standard requirement can still be met when the maximum transmission rate outputs higher power, the power saturation point and the quiescent current are required to be higher. The power backoff process can only ensure that the working current is closer to the quiescent current, and if the quiescent current is originally in a high level, the current optimization is limited, and the transmission efficiency is lower. The quiescent current refers to the current when no signal is input, and the power back-off refers to the back-off of the output power of the power amplifier, so that the power amplifier is far away from a saturation region and enters a linear working region, thereby maintaining the linearity of the power amplifier, namely, the output power is kept within an average power range.
To address the need for meeting vector error criteria during power backoff, improving transmission efficiency may be accomplished by modifying the power amplifier 160. The wireless lan belongs to a time division duplex system, which is a duplex mode of a communication system, and is used for separating a receiving channel and a transmitting channel in a mobile communication system. In a time division duplex mobile communication system, reception and transmission are performed in different time slots of the same frequency channel, i.e., carrier, and the reception and transmission channels are separated by a guaranteed time.
The power amplifier 160 may have a plurality of operation modes, and the plurality of operation modes may be switched with each other. Each working mode can comprise different power ranges, namely the maximum output power of the power amplifier in any transmission mode can be divided into a plurality of power ranges, and when the output power is detected to be in the different power ranges, the power amplifier corresponds to different working modes.
Wherein each transmission mode may transmit a target transmission rate in a different mode of operation of the power amplifier 160. For example, in the 11ax transmission mode, the power amplifier 160 may transmit the target transmission rate, i.e., 11ax mcs11, in different operation modes; in the 11n transmission mode, the power amplifier 160 may transmit the target transmission rate, i.e., 11n MCS7, in different operation modes.
Referring to fig. 3, fig. 3 is a second structural block diagram of an electronic device according to an embodiment of the present application. The electronic device may also include a low noise amplifier 170 and a switch assembly 180.
It should be noted that, the power amplifier 160, the low noise amplifier 170, and the switch assembly 180 may be integrated in a radio frequency front end module, and the radio frequency front end module may further include a filter, a duplexer, a receiver, a transmitter, and the like. The power amplifier is used for amplifying the radio frequency signals of the transmitting channel; the filter is used for filtering the transmitting and receiving signals; the diplexer is used for switching the time division duplex system and filtering radio frequency signals of the receiving/transmitting channels; the switch assembly 180 is used for switching between the receiving and transmitting channels; the low noise amplifier 170 is used for amplifying small signals in the receive channel; the receiver and the transmitter are used for frequency conversion and channel selection of the radio frequency signals.
The power amplifier 160 may have a first signal and a second signal, wherein the first signal may be a pa_en signal and the second signal may be a pa_m signal. The low noise amplifier 170 may have a third signal, which may be an lna_en signal. The pa_en signal and the lna_en signal can control the power amplifier 160 and the low noise amplifier 170 to be turned on, and the pa_m signal, which is a second signal, can be added to achieve that the power amplifier 160 is switched between a plurality of operation modes, and the power supply voltage is 4V.
The switch assembly 180 may be disposed inside the power amplifier 160, i.e., an internal component of the power amplifier 160, or may be electrically connected to the power amplifier 160, i.e., an external component of the power amplifier 160, and fig. 3 illustrates a state in which the switch assembly 180 is electrically connected to the power amplifier 160. The switching assembly 180 may switch the operation mode of the power amplifier 160 by controlling the level values of the first signal, the second signal, and the third signal.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a switch assembly in an electronic device according to an embodiment of the present application. The switch assembly 180 may include a single pole double throw switch and a single pole triple throw switch. The switch assembly 180 may be connected to the high level or low level pins of the first signal, the second signal, and the third signal to control the level values of the three signals, where the first signal, the second signal, and the third signal are the pa_en signal, the pa_m signal, and the lna_en signal, respectively. For example, one end of the single pole double throw switch with two pins is respectively connected with the first signal and the second signal, and one end of the single pole triple throw switch with three pins is respectively connected with the first signal, the second signal and the third signal.
Referring to fig. 5, fig. 5 is a third structural block diagram of an electronic device according to an embodiment of the present application. The electronic device 100 may also include a processor 190 and a memory 200. Processor 190 may be used to process various operations of electronic device 100, processor 190 and memory 200 may be integrated on circuit board 130, processor 190 being electrically connected to detector 150, power amplifier 160, low noise amplifier 170 and switch assembly 180, respectively.
The different operation modes of the power amplifier 160 may have a first operation mode, a second operation mode, and a third operation mode. Processor 190 may determine the corresponding target power based on the target transmission rate in the current transmission mode detected by detector 150; when the target power is within the power range of the first operating mode, controlling the power amplifier 160 to operate in the first operating mode; when the target power is reduced to the first preset power, the working mode of the power amplifier 160 is controlled to be switched from the first working mode to the second working mode; when the first preset power drops to the second preset power, the operation mode of the power amplifier 160 is controlled to switch from the second operation mode to the third operation mode.
It should be noted that, the above-mentioned switching of the operation mode of the power amplifier 160 from the first operation mode to the third operation mode, the target power is reduced to the second preset power, i.e. the power backoff process. The switching of the operation mode of the power amplifier 160 may also be from the third operation mode to the first operation mode, which is not particularly limited herein.
The first operation mode of the power amplifier 160 may be a high power mode, the second operation mode may be a medium-high power mode, and the third operation mode may be a low power mode. The first preset power and the second preset power need to be smaller than the target power in the current working mode, namely the maximum output power, and the second preset power is smaller than the first preset power.
Referring to fig. 6, fig. 6 is a schematic diagram of a current curve after power consumption optimization of an electronic device according to an embodiment of the present application. For example, the first preset power is set to 10dBm and the second preset power is set to 3dBm. The power backoff process of the power amplifier 160 may specifically be: the detector 150 detects that the current transmission mode of the electronic device is an 11ax transmission mode, the target transmission rate thereof may be 11ax ms 11, it is determined that the target power corresponding to the target transmission rate is 13dBm, and the power range of the high power mode of the power amplifier 160 is 0 to 13dBm, that is, the target power is within the power range of the high power mode, and the power amplifier 160 operates in the high power mode; when the target power of 13dBm drops to the first preset power of 10dBm, the working mode of the power amplifier 160 is switched from the high power mode to the medium-high power mode; when the first preset power of 10dBm drops to the second preset power of 3dBm, the working mode of the power amplifier 160 is switched from the high power mode to the low power mode, and the synthetic curve in fig. 6 is a process of optimizing the power consumption of the electronic device in the 11ax transmission mode.
When the electronic device 100 transmits data in the 11ax transmission mode, the transmission rate is still maintained at the target transmission rate 11ax mcs11 by switching the operation mode of the power amplifier 160, i.e., switching from the high power mode to the medium-high power mode and then to the low power mode.
As can be seen from the above, in the process of power backoff of the power amplifier 160, different operation modes of the power amplifier 160 are switched, so that the target transmission rate of the electronic device 100 in each transmission mode is ensured to be unchanged, but the operation mode can be switched from the high-power mode to the low-power mode, the output power is reduced, but the output efficiency is not changed, thereby reducing the overall power consumption of the electronic device 100 and achieving the effect of optimizing the power consumption of the electronic device 100. In addition, the electronic device 100 is powered by the battery 140, so that the power consumption of the battery 140 can be reduced, and the power saving effect can be achieved.
In some embodiments, the current transmission mode of the electronic device 100 may include a first transmission mode and a second transmission mode, the first transmission mode corresponding to a first target power and the second transmission mode corresponding to a second target power. Processor 190 may control power amplifier 160 to operate in the first mode of operation when the first target power is within a power range of the first mode of operation; when the first target power drops to the first preset power, the working mode of the power amplifier 160 is controlled to be switched from the first working mode to the second working mode; when the first preset power drops to the second preset power, the operation mode of the power amplifier 160 is controlled to switch from the second operation mode to the third operation mode.
For example, the first transmission mode may be an 11ax transmission mode, as described above, the target transmission rate of the 11ax transmission mode may be 11ax ms 11, the target power corresponding to the target transmission rate is determined to be 13dBm, and the power range of the high power mode of the power amplifier 160 is 0 to 13dBm, that is, the target power is within the power range of the high power mode, and then the power amplifier 160 operates in the high power mode; when the target power of 13dBm drops to the first preset power of 10dBm, the working mode of the power amplifier 160 is switched from the high power mode to the medium-high power mode; when the first preset power of 10dBm drops to the second preset power of 3dBm, the operating mode of the power amplifier 160 is switched from the high power mode to the low power mode.
For example, the third preset power is set to 12dBm and the fourth preset power is set to 5dBm. The second transmission mode may be an 11n transmission mode, the target transmission rate may be 11n ms 7, it is determined that the target power corresponding to the target transmission rate is 15dBm, and the power range of the high power mode of the power amplifier 160 is 0 to 15dBm, that is, the target power is within the power range of the high power mode, and then the power amplifier 160 operates in the high power mode; when the target power of 13dBm drops to the third preset power of 12dBm, the working mode of the power amplifier 160 is switched from the high power mode to the medium-high power mode; when the third preset power 12dBm drops to the fourth preset power 5dBm, the operating mode of the power amplifier 160 is switched from the high power mode to the low power mode.
It may be appreciated that when the electronic device 100 is in different transmission modes, different preset powers, such as 11n ms 7 transmission rate corresponding to 11n transmission mode, 11ax ms 11 transmission rate corresponding to 11ax transmission mode, are selected for the power amplifier 160 in the power backoff process according to the target powers corresponding to different transmission rates in the different transmission modes, i.e., the maximum output powers, the 11n transmission modes select 12dBm and 5dBm as preset power switching points from the high power mode to the medium high power mode and from the medium high power mode to the low power mode, and the 11ax transmission modes select 10dBm and 3dBm as preset power switching points from the high power mode to the medium high power mode and from the medium high power mode to the low power mode. The power consumption of the electronic equipment can be optimized more by selecting different preset power switching points according to different transmission rates of different transmission modes and different corresponding vector errors.
In some embodiments, the different modes of operation of the power amplifier 160 may have a first mode of operation and a second mode of operation. Processor 190 may determine the corresponding target power based on the target transmission rate in the current transmission mode detected by detector 150; when the target power is within the power range of the first operating mode, controlling the power amplifier 160 to operate in the first operating mode; when the target power drops to the first preset power, the operation mode of the power amplifier 160 is controlled to switch from the first operation mode to the second operation mode.
It should be noted that, the above-mentioned switching of the operation mode of the power amplifier 160 from the first operation mode to the second operation mode, the target power is reduced to the first preset power, i.e. the power backoff process. The switching of the operation mode of the power amplifier 160 may also be from the second operation mode to the first operation mode, which is not particularly limited herein.
The first operation mode of the power amplifier 160 may be a high power mode, and the second operation mode may be a medium-high power mode. The first preset power needs to be smaller than the target power, i.e. the maximum output power, in the current working mode.
For example, the first preset power is set to 7dBm. The power backoff process of the power amplifier 160 may specifically be: the detector 150 detects that the current transmission mode of the electronic device is an 11ax transmission mode, the target transmission rate thereof may be 11ax ms 11, it is determined that the target power corresponding to the target transmission rate is 13dBm, and the power range of the high power mode of the power amplifier 160 is 0 to 13dBm, that is, the target power is within the power range of the high power mode, and the power amplifier 160 operates in the high power mode; when the target power 13dBm drops to the first preset power 7dBm, the operating mode of the power amplifier 160 is switched from the high power mode to the medium-high power mode.
In some embodiments, the electronic device 100 may also include a noise amplifier 170 and a switch assembly 180. Processor 190 may control power amplifier 160 to operate in the first mode of operation when switch assembly 180 controls the first signal to be high, the second signal to be low, and the third signal to be low; when the switching assembly 180 controls the first signal to be at a high level, the second signal to be at a high level, and the third signal to be at a low level, the power amplifier 160 is controlled to operate in the first operation mode; when the switching assembly 180 controls the first signal to be at a high level, the second signal to be at a high level, and the third signal to be at a high level, the power amplifier 160 is controlled to operate in the first operation mode. I.e., the switching assembly 180 switches the operation mode of the power amplifier 160 by controlling the level values of the first signal, the second signal, and the third signal.
In addition, processor 190 may also obtain a maximum limited power of electronic device 100 in the current transmission mode; comparing the target power with the maximum limiting power when the target power is in the power range of the first working mode in the current transmission mode, and obtaining a comparison result; if the comparison result shows that the target power is larger than the maximum limiting power, determining that the power amplifier works in the second working mode; if the comparison result is that the target power is less than or equal to the maximum limiting power, then it is determined that the power amplifier 160 is operating in the first operating mode.
It should be noted that, taking the 11ax transmission mode as an example, the transmission rate of 11ax may include 11ax MCS0-11, the target power corresponding to 11ax MCS0 is 21dBm, and the maximum limiting power is 18dBm; the target power corresponding to 11ax MCS1 is 21dBm, and the maximum limiting power is 18dBm; the target power corresponding to 11ax MCS2 is 20dBm, and the maximum limiting power is 18dBm; the target power corresponding to 11ax MCS3 is 19dBm, and the maximum limiting power is 18dBm; the target power corresponding to 11ax MC S4 is 18dBm, and the maximum limiting power is 18dBm; the target power corresponding to 11ax MC 5 is 17dBm, and the maximum limiting power is 17dBm; the target power corresponding to 11ax MCS6 is 16dBm, and the maximum limiting power is 16dBm; the target power corresponding to 11ax MC S7 is 15dBm, and the maximum limiting power is 15dBm; the target power corresponding to 11ax MCS8 is 14dBm, and the maximum limiting power is 14dBm; the target power corresponding to 11ax MCS9 is 14dBm, and the maximum limiting power is 14dBm; the target power corresponding to 11ax MCS10 is 13dBm, and the maximum limiting power is 13dBm; the target power corresponding to 11ax MCS11 is 13dBm, and the maximum limiting power is 13dBm.
The target power corresponding to 11ax MCS0-3 exceeds the maximum limiting power, and the target power is limited, which can be understood as the vector error margin is sufficient, so that the power amplifier 160 can directly work in the second working mode at the transmission rate of 11ax MCS0-3; and the target power corresponding to 11ax ms 4-11 is less than or equal to the maximum limit power, the power amplifier 160 may be enabled to perform power backoff in the manner of switching from the first operation mode to the third operation mode or from the first operation mode to the second operation mode, i.e. the power amplifier 160 operates in the first operation mode. The second working mode is a medium-high power mode, the first working mode is a high power mode, and the third working mode is a low working mode.
From the above, in different transmission rates of the electronic device in different transmission modes, under the condition that the maximum output power is greater than the maximum limiting power, the power amplifier can directly start to perform power backoff in the middle-high power mode under the transmission rate, and the power consumption of the electronic device caused by the operation of the power amplifier in the high power mode can be correspondingly reduced, so that the power consumption of the electronic device is optimized.

It should be noted that, the above-mentioned switching of the power amplifier operation mode is from the first operation mode to the third operation mode, and the target power is reduced to the second preset power, i.e. the power back-off process. The switching of the power amplifier operation mode may also be from the third operation mode to the first operation mode, which is not particularly limited herein.
