Description
Technical Field
The present disclosure relates to an electronic apparatus and a control method for the electronic apparatus.
Background
PC2, also referred to as "UE Power Class 2". In 3G and 4G networks, a user terminal is called "UE" and includes a mobile phone, an intelligent terminal, multimedia equipment, streaming media equipment, and the like; power Class refers to Power Class. It is understood that the PC2 literally means that the user terminal operates at the maximum output power specified by power class 2.
Although the UE does not always operate at the maximum output power, it is sufficient to define the maximum output power operation — in fact, the maximum output power of the UE limits the transmission distance of the mobile communication uplink. Currently, for most 4G LTE bands (except B14, which is applied in public safety), 3GPP specifies only one Power Class, Power Class 3 (hereinafter referred to as PC3), which limits the maximum output Power of the UE to a level of 23dBm +/-2.
However, as wireless networks develop, the limitation of the PC3 becomes more and more obvious, and the advantage of the PC2 becomes more and more prominent. Currently, the us operators have launched a commercial product supporting PC 2. According to the standard definition, the PC2 increases the maximum output power of the UE by a level of 3dBm to 26dBm +/-2 on the basis of the PC3 (23dBm can be converted to 200mW, and 26dBm can be converted to 400mW), which almost doubles the maximum output power of the UE. In order to make a Power Amplifier (PA) output higher Power, a high voltage and a large current need to be supplied to the PA.
Currently, a related art implementation provides an open-loop control circuit as shown in fig. 1. In implementing the disclosed concept, the inventors found that there are at least the following drawbacks in the related art:
in the open-loop control circuit shown in fig. 1, if the threshold voltage is not set, as long as the UE enters the band, i.e. frequency band, supporting the PC2, the boost IC enters the boost mode regardless of whether the current output power of the PA needs high voltage support, which results in power waste.
In addition, in the open-loop control circuit shown in fig. 1, if the threshold voltage is set, since the current output power and the required voltage of the PA cannot be known, the threshold voltage constant value is likely not to be adapted to the required operating voltage of the PA. If the system voltage Vph _ pwr is 3.8V, and if the threshold voltage is set to be lower than 3.4V, if the UE output power is required to reach the maximum output power of 26dBm, the operating voltage of the PA needs to reach 4.3V, but since Vph _ pwr 3.8V is greater than the threshold voltage of 3.4V, the Boost IC always operates in bypass mode, i.e., pass mode, which results in insufficient supply voltage of the PA and insufficient power output, otherwise, if the threshold voltage is set to be higher, useless Boost IC occurs.

Fig. 2 schematically shows an application scenario of a UE according to an embodiment of the present disclosure.

In 3G, 4G networks, the UE typically operates at the maximum output power specified by PC3, and in 5G networks, the UE typically operates at the maximum output power specified by PC 2. As shown in FIG. 2, with the development of wireless networks, in a 5G network, the maximum output power of the UE is increased by a level of 3dBm to 26dBm +/-2 on the basis of PC3 at PC2, which almost doubles the maximum output power of the UE. However, in order to make the PA output higher power, it is necessary to supply a high voltage and a large current to the PA.
To address this problem, the prior open-loop control circuit shown in fig. 1 provides two solutions, namely, no threshold voltage setting or threshold voltage setting. If the threshold voltage is not set, as long as the UE enters the band, i.e. frequency band, supporting the PC2, the boost IC will enter the boost mode regardless of whether the current output power of the PA needs high voltage support, resulting in power waste. If the threshold voltage is set, the threshold voltage fixed value is probably unable to adapt to the working voltage required by the PA because the current output power and the required voltage of the PA cannot be known. If the system voltage Vph _ pwr is 3.8V, and if the threshold voltage is set to be lower than 3.4V, if the UE output power is required to reach the maximum output power of 26dBm, the operating voltage of the PA needs to reach 4.3V, but since Vph _ pwr 3.8V is greater than the threshold voltage of 3.4V, the Boost IC always operates in bypass mode, i.e., pass mode, which results in insufficient supply voltage of the PA and insufficient power output, otherwise, if the threshold voltage is set to be higher, useless Boost IC occurs.
To overcome the above-mentioned drawbacks of the prior art, the present disclosure provides an improved electronic device and a control method for the electronic device.
Fig. 3A and 3B schematically illustrate a schematic diagram of an electronic device and its implementing circuitry according to an embodiment of the disclosure.
As shown in fig. 3A, the electronic device 300 includes: a power amplifier 301, a voltage processing module 302 and a comparator 303.
The power amplifier 301 is configured to amplify a power signal of the electronic device.
A voltage processing module 302 having a boost mode and a pass-through mode, wherein in the boost mode, the voltage processing module is configured to boost a system voltage of the electronic device to adapt an operating voltage of the power amplifier.
It should be noted that, in the embodiment of the present disclosure, the system voltage of the electronic device may be a voltage provided by a power supply of the electronic device, where the power supply includes a battery or a household 110V-220V ac power supply.
Generally, assuming that the power supply voltage (i.e., the system voltage) of the electronic device is represented as Vph _ pwr and the operating voltage of the PA is represented as Vpa _ pwr, if Vph _ pwr > Vpa _ pwr, it indicates that the power supply of the electronic device can provide enough operating voltage for the PA, and then generally no boosting is needed unless the circuit loss is too large, and thus the control voltage processing module 302 operates in the pass-through mode, and if Vph _ pwr ≦ Vpa _ pwr, it indicates that the power supply of the electronic device cannot provide enough operating voltage for the PA, and then generally boosting is needed, and thus the control voltage processing module 302 operates in the boost mode.
A comparator 303, configured to control an operating mode of the voltage processing module by comparing a system voltage of the electronic device with an operating voltage of the power amplifier, wherein if the system voltage of the electronic device is lower than the operating voltage of the power amplifier, the voltage processing module is controlled to operate in the boost mode; and/or controlling the voltage processing module to work in the through mode if the system voltage of the electronic device is higher than the working voltage of the power amplifier.
For example, as shown in fig. 2 and 3B, for a high power UE, if its uplink signal is too weak, the base station will generally require the UE to operate at the maximum output power specified by PC2, and to make the UE output power reach 26dBm, the operating voltage of the PA will generally need to reach 4.3V, and the power supply voltage will generally be set to 3.8V, which requires the voltage processing module 302 to operate in the boost mode. Of course, if the uplink signal of the UE is strong enough, and the UE can operate with a smaller output power to meet the requirement of the base station, it may be enough that the operating voltage of the PA is less than 3.8V, and at this time, the voltage processing module 302 can be controlled to operate in the pass-through mode.
Compared with the prior art, the working voltage of the PA is controlled through the open-loop circuit, so that if the threshold voltage is not set, the boost IC (namely, a voltage processing module) can enter a boost mode as long as the UE enters the band supporting the PC2, and no matter whether the current output power of the PA needs high-voltage support, the electric quantity is wasted; if the threshold voltage is set, because the current output power and the required voltage of the PA cannot be known, and the threshold voltage fixed value is probably unable to adapt to the working voltage required by the PA, "compared with the prior art, the embodiment of the present disclosure can form a closed-loop circuit for the voltage processing module 302 by setting a comparator, so that the adaptive working voltage Vapt can be provided for the PA according to the current output power of the PA, that is, the adaptation can be ensured, and no electric quantity can be consumed, so that the standby communication time of the whole machine can be prolonged.
The electronic device shown in fig. 3A and 3B is further described with reference to fig. 4A and 4B and fig. 5 in conjunction with specific embodiments.
As an alternative embodiment, as shown in fig. 4A, the electronic device 300 may further include: a power/voltage management module 401, configured to determine an operating voltage required by the power amplifier according to a power output requirement of the electronic device from the base station, and provide the determination result to the comparator 303.
In the embodiment of the present disclosure, when the UE communicates with the base station, the base station may sense the strength of the current uplink signal of the UE, and request the output power corresponding to the UE to operate according to the strength of the current uplink signal of the UE, but the embodiment of the present disclosure sets a power/voltage management module 401, so that the current required operating voltage of the PA may be determined according to the power output requirement of the base station for the UE, and then the current required operating voltage of the PA is provided to the comparator 303.
Specifically, a power/voltage table may be preset, as shown in table 1, so that the power/voltage management module 401 may simply look up the table according to the output power required by the base station to determine the current required operating voltage of the PA.
TABLE 1
| Output power of PA | Operating voltage of PA |
| P1 | V1 |
| P2 | V2 |
| ...... | ...... |
| Pn | Vn |
As shown in fig. 4B, the power/voltage management module 401 may be disposed between the voltage processing module 302 and the power amplifier 301.
Compared with the prior art that the current output power of the PA cannot be known to cause difficulty in providing adaptive working voltage for the PA, the embodiment of the disclosure, by providing the power/voltage management module, informs the UE of how much output power the UE needs to work currently according to the current communication quality of the uplink of the UE, so that the power/voltage management module can determine the working voltage adaptive to the output power according to the preset power/voltage table, thereby overcoming the above-mentioned defects in the prior art.
As an alternative embodiment, the power/voltage management module may be further configured to: when the voltage processing module works in the through mode, the system voltage of the electronic device is reduced to adapt to the working voltage of the power amplifier.
As previously mentioned, the output power requirements of the UE from the base station are typically determined based on the current uplink signal strength of the UE. If the uplink signal of the UE is strong enough, and the UE can meet the requirement of the base station by operating with a smaller output power, it may be enough that the operating voltage of the PA is less than 3.8V, and at this time, the voltage processing module 302 can be controlled to operate in the through mode. However, if no voltage reduction measure is taken, it is assumed that the current operating voltage of the PA only needs to reach 2.6V to sufficiently meet the power output requirement of the base station for the UE, and it is obvious that the system voltage 3.8V of the electronic device is much greater than 2.6V when the circuit loss is ignored, thereby causing power waste and shortening the standby time of the device.
Through this disclosed embodiment, not only can utilize voltage processing module to boost to system's voltage, can also utilize the step-down function of power/voltage management module to step down system's voltage under the through mode to can avoid providing the operating voltage that the PA was higher than its actual operating voltage that needs, lead to the electric quantity extravagant.
As an alternative embodiment, as shown in fig. 5, the electronic device may further include: the power supply module Vph _ pwr is used for providing system voltage for the electronic equipment; and a resistor R connected between the power supply module Vph _ pwr and the system voltage input terminal of the comparator 303.
Since the circuit has more or less general loss, if the system voltage of the electronic device is equal to or slightly greater than the operating voltage required by the PA, simply controlling the voltage processing module in the through mode would likely cause the output power of the electronic device to fail to meet the requirements of the base station.
As an alternative embodiment, the resistor comprises an adjustable resistor, so that different electronic devices can be adapted, and the use is more flexible.
As an alternative embodiment, the electronic device supports the relevant frequency band of the PC 2. The electronic devices supporting the relevant frequency band of the PC2 are typically high power devices.
Through the embodiment of the disclosure, under the scene that high power needs to be output, not only can the high enough working voltage be guaranteed to be provided, but also the electric quantity can be prevented from being wasted.
Fig. 6 schematically shows a flow chart of a control method for an electronic device according to an embodiment of the present disclosure.
As shown in fig. 6, the method includes operations S601 to S604, in which:
in operation S601, a system voltage of the electronic device and an operating voltage of a power amplifier of the electronic device are obtained, where the power amplifier is configured to amplify a power signal of the electronic device;
comparing, by a comparator, a system voltage of the electronic device and an operating voltage of the power amplifier in operation S602;
in operation S603, if the system voltage of the electronic device is lower than the operating voltage of the power amplifier, controlling the voltage processing module of the electronic device to operate in a boost mode; and/or
In operation S604, if the system voltage of the electronic device is higher than the operating voltage of the power amplifier, the voltage processing module is controlled to operate in a pass-through mode, wherein in the boost mode, the voltage processing module is capable of boosting the system voltage of the electronic device to adapt to the operating voltage of the power amplifier.
Compared with the prior art, the working voltage of the PA is controlled through the open-loop circuit, so that if the threshold voltage is not set, the boost IC (namely, a voltage processing module) can enter a boost mode as long as the UE enters the band supporting the PC2, and no matter whether the current output power of the PA needs high-voltage support, the electric quantity is wasted; if the threshold voltage is set, because the current output power and the required voltage of the PA cannot be known, and the threshold voltage fixed value is probably unable to adapt to the working voltage required by the PA, "compared with the prior art, the embodiment of the present disclosure can form a closed-loop circuit for the voltage processing module 302 by setting a comparator, so that the adaptive working voltage Vapt can be provided for the PA according to the current output power of the PA, that is, the adaptation can be ensured, and no electric quantity can be consumed, so that the standby communication time of the whole machine can be prolonged.
As an alternative embodiment, the method further comprises: and enabling the power/voltage management module to determine the working voltage required by the power amplifier according to the power output requirement of the base station on the electronic equipment, and sending the determination result to the comparator.
Compared with the prior art that the current output power of the PA cannot be known to cause difficulty in providing adaptive working voltage for the PA, the embodiment of the disclosure, by providing the power/voltage management module, informs the UE of how much output power the UE needs to work currently according to the current communication quality of the uplink of the UE, so that the power/voltage management module can determine the working voltage adaptive to the output power according to the preset power/voltage table, thereby overcoming the above-mentioned defects in the prior art.
As an alternative embodiment, the method further comprises: when the voltage processing module works in the through mode, the system voltage of the electronic device is reduced through the power/voltage management module so as to adapt to the working voltage of the power amplifier.
Through this disclosed embodiment, not only can utilize voltage processing module to boost to system's voltage, can also utilize the step-down function of power/voltage management module to step down system's voltage under the through mode to can avoid providing the operating voltage that the PA was higher than its actual operating voltage that needs, lead to the electric quantity extravagant.
As an alternative embodiment, the method further comprises: and adjusting the voltage of the system voltage input end of the comparator through a resistor, wherein the resistor is connected between a power supply module and the system voltage input end of the comparator, and the power supply module is used for providing the system voltage for the electronic equipment.
Because the circuit has more or less general loss, if the system voltage of the electronic device is equal to or slightly greater than the operating voltage required by the PA, simply controlling the voltage processing module in the through mode would likely cause the output power of the electronic device to fail to meet the requirements of the base station.
