The following describes in detail a power supply method of a radio frequency circuit provided in the embodiments of the present application with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
The embodiment of the present application relates to a power supply method for a radio frequency circuit, where the radio frequency circuit may be applied in an electronic device product, the radio frequency circuit may be the radio frequency circuit 10 shown in fig. 1, and the radio frequency circuit 10 includes a transceiver 110, a power management module 120, a 4G power amplifier 130, and a 5G power amplifier 140. The electronic device may be a mobile phone, a tablet computer, a notebook computer, a palm computer, or a wearable device, and is not limited herein. The following embodiments will be described with the execution main body as an electronic apparatus.
As shown in fig. 2, the power supply method of the rf circuit may include the following steps S2100 to S2300:
in step S2100, when the electronic device operates in the 4G network mode or the 5G network mode independently, the power management module 120 is controlled to provide the voltage required for the operation of the 4G power amplifier 130 or the 5G power amplifier 140.
In this step S1100, for a scenario in which the electronic device independently operates in the 4G network mode or the 5G network mode, in this case, the 5G network mode is an independent networking SA, and each frequency band of the 4G and each frequency band of the 5G do not operate simultaneously in this scenario, it can be understood that the electronic device operating in the 4G network mode includes that the electronic device operates in each frequency band of the 2G, the 3G, and the 4G network mode, where the 2G includes, for example and without limitation, a gsm (global System for Mobile communications) technology and a Wideband Code Division Multiple Access (WCDMA) technology, and the 3G includes, for example and without limitation, a WCDMA technology and a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) technology, and the 4G includes, for example and without limitation, a long Term evolution (lte) technology. Under the scenario, the 4G/5G supported frequency bands are, for example, but not limited to, the following table 1:
| systems of | Supporting frequency bands |
| 5G | SA:N1/3/28/41/77/78/79 |
| 4G | LTE:B1/2/3/4/5/7/8/12/17/25/26/34/38/39/40/41 |
| 3G | WCDMA:B1/2/4/5/8,TD-SCDMA:B34/39 |
| 2G | GSM:850/900/1800/1900,CDMA:BC0/BC1 |
In one example, in the case where the electronic device operates in the 4G network mode independently, it can control the power management module 120 to provide the voltage required for the 4G power amplifier to operate, i.e., the power management module 120 can supply power to the 4G power amplifier 130. The 4G network mode may be any one of a Time-Division Duplex (TDD) mode and a Frequency-Division Duplex (FDD) mode.
It can be understood that, in the case that the 4G network mode is the time division duplex mode, as shown in the first time division operation diagram of fig. 3, the receiving and transmitting of the 4G signal are performed in different time slots of the same radio frequency point, for example, the transmitting of the 4G signal is time slot a and time slot c, and the receiving of the 4G signal is time slot b and time slot d. Since the signal is received without passing through the 4G power amplifier, the 4G power amplifier is not operated when the signal is received through the time slot b and the time slot d, and power supply for the 4G power amplifier is not needed. The 4G power amplifier is only active when transmitting signals through time slot a and time slot c, and the 4G power amplifier needs to be powered.
Under the condition that the 4G network mode is the frequency division duplex mode, the receiving and transmitting of the 4G signals are performed simultaneously at different radio frequency points, the 4G power amplifier is always working, and the power management module 120 needs to always supply power to the 4G power amplifier.
In this example, when the electronic device operates in the 4G network mode independently, the Power management module 120 is controlled to provide the voltage required by the operation of the 4G Power amplifier in an Average Power Tracking (APT) Power supply mode or an Envelope Tracking (ET) Power supply mode, so as to achieve the purpose of optimal Power saving.
In this example, as shown in fig. 3, the 4G power amplifier 130 includes a low-frequency power amplifier 131 and a medium-high-frequency power amplifier 132, and in the case where the electronic device operates independently in the 4G network mode or the 5G network mode, only the low-frequency power amplifier 131 or the medium-high-frequency power amplifier 132 operates at the same time.
In another example, in the case where the electronic device operates in the 5G network mode independently, it can control the power management module 120 to provide the voltage required for the 5G power amplifier to operate, i.e., the power management module 120 can supply power to the 5G power amplifier. The 5G network mode may be any one of a time division duplex mode and a frequency division duplex mode.
It can be understood that, in the case that the 5G network mode is the time division duplex mode, as shown in the second time division operation diagram shown in fig. 3, the receiving and transmitting of the 5G signal are performed in different time slots of the same radio frequency point, for example, the transmitting of the 5G signal is time slot e and time slot G, and the receiving of the 5G signal is time slot f and time slot h. Since the signal is received without passing through the 5G power amplifier, the 5G power amplifier is not operated when the signal is received through the time slot f and the time slot h, and the 5G power amplifier is not required to be powered at this time. The 5G power amplifier is only active when transmitting signals via time slot e and time slot G, and the 5G power amplifier needs to be powered.
Under the condition that the 5G network mode is the frequency division duplex mode, the receiving and transmitting of the 5G signals are performed at different radio frequency points simultaneously, the 5G power amplifier is always working, and the power management module 120 needs to always supply power to the 5G power amplifier.
In this example, when the electronic device operates in the 5G network mode independently, the power management module 120 is controlled to provide the voltage required by the 5G power amplifier in the APT power supply mode or the ET power supply mode, so as to achieve the purpose of optimal power saving.
Illustratively, one power management module 120 may be utilized to power the 4G power amplifier 130 and the 5G power amplifier 140, respectively, and the ET power mode may be employed to achieve optimal performance and optimal power consumption for either 4G or 5G. For example, when the electronic device operates in the 4G network mode and the first switch inside the medium-high frequency power amplifier 132 is closed, that is, only the medium-high frequency power amplifier 132 operates, the power management module 120 can supply power to the medium-high frequency power amplifier 132 based on the ET power supply mode. For another example, when the electronic device operates in the 5G network mode, the second switch inside the 5G power amplifier 140 is closed, that is, the 5G power amplifier 140 operates, and the power management module 120 can supply power to the 5G power amplifier 140 based on the ET power supply mode.
Step S2200 is that, when the electronic device simultaneously operates in the 4G network mode and the 5G network mode, and both the 4G network mode and the 5G network mode are the time division duplex mode, the power management module 120 is controlled to provide the voltage required by the operation of the 4G power amplifier 130 in the first time period, and provide the voltage required by the operation of the 5G power amplifier 140 in the second time period.
The above first time period is different from the second time period.
In this step S2200, for a scenario where the electronic device operates in an NSA non-independent networking, for example, the electronic device operates in a 4G network mode and a 5G network mode simultaneously, and the 4G network mode and the 5G network mode are both in a time division duplex mode, where each frequency band of 4G and each frequency band of 5G operate simultaneously, and the supported frequency bands in the scenario are, for example, but not limited to, the following table 2:
| TDD+TDD |
| DC_B39-N41 |
| DC_B39-N79 |
| DC_38A-n78A |
| DC_40A-n78A |
| DC_B40-N41 |
| DC_B40-N79 |
in step S2200, for TDD + TDD scenarios, LTE and 5G are asynchronous, that is, when LTE is transmitted, 5G does not require transmission at the same time, so that time division power supply technology can be used in the scenario, and there is no limitation in 3GPP protocols and the feasibility is high.
In one example, in the case that the electronic device is simultaneously operated in the 4G network mode and the 5G network mode, and both the 4G network mode and the 5G network mode are the time division duplex mode, it can control the power management module 120 to provide the voltage required for the 4G power amplifier 130 to operate in the first time period, and provide the voltage required for the 5G power amplifier 140 to operate in the second time period.
It can be understood that, since LTE and 5G are asynchronous in this scenario, i.e. LTE transmits, 5G does not require simultaneous transmission, as shown in the time division operation diagram of fig. 3, the vertical bar box represents a 4G transmission slot, the horizontal bar box represents a 4G reception slot, the left slash box represents a 5G transmission slot, and the right slash box represents a 5G reception slot, it can be seen from fig. 3 that the 4G transmission slot and the 5G transmission slot are staggered, and only the 4G power amplifier 130 or the 5G power amplifier 140 operates at the same transmission time.
In this example, when the electronic device simultaneously operates in the 4G network mode and the 5G network mode, and both the 4G network mode and the 5G network mode are the time division duplex mode, the power management module 120 is controlled to provide the voltage required for the operation of the 4G power amplifier 130 in the APT power supply mode or the ET power supply mode in the first time period, and to provide the voltage required for the operation of the 5G power amplifier 140 in the APT power supply mode or the ET power supply mode in the second time period, so as to achieve the purpose of optimal power saving.
Step S2300, controlling the power management module 120 to simultaneously provide the voltages required by the operations of the 4G power amplifier 130 and the 5G power amplifier 140 with the target voltages when the electronic device is simultaneously operated in the 4G network mode and the 5G network mode, and at least one of the 4G network mode and the 5G network mode is the frequency division duplex mode.
The above target voltage is the larger one of the voltage required for the 4G power amplifier to operate and the voltage required for the 5G power amplifier to operate.
In this step S2300, for example, when the electronic device operates in the NSA non-independent networking, the electronic device operates in the 4G network mode and the 5G network mode simultaneously, and the 4G network mode and the 5G network mode are scenarios of TDD + FDD, FDD + FDD, or FDD + TDD, in which the 4G frequency bands and the 5G frequency bands operate simultaneously, and the supported frequency bands in the scenarios are, for example, but not limited to, the following table 3:
in this embodiment, when the electronic device simultaneously operates in the 4G network mode and the 5G network mode, and at least one of the 4G network mode and the 5G network mode is the frequency division duplex mode, it can control the power management module 120 to simultaneously provide the voltages required for the operations of the 4G power amplifier 130 and the 5G power amplifier 140 at the target voltage. For example, first, a first voltage required for the current operation of the 4G power amplifier and a second voltage required for the current operation of the 5G power amplifier are obtained, and a maximum voltage of the first voltage and the second voltage is obtained as a target voltage, so as to control the power management module 120 to simultaneously provide the voltages required for the operation of the 4G power amplifier 130 and the 5G power amplifier 140 at the target voltage.
It is understood that LTE and 5G may be synchronized in this scenario, i.e. when LTE transmits, 5G also transmits.
In this embodiment, when the electronic device simultaneously operates in the 4G network mode and the 5G network mode, and at least one of the 4G network mode and the 5G network mode is the frequency division duplex mode, the power management module 120 is controlled to provide the voltage required by the operation of the 4G power amplifier 130 and the 5G power amplifier 140 in the APT power supply mode, so as to achieve the purpose of optimal power saving.
Illustratively, one power management module 120 may be utilized to power the 4G power amplifier 130 and the 5G power amplifier 140, respectively, and may employ the PAT power mode to achieve the optimal performance of 4G or 5G. For example, the electronic device operates in TDD + FDD, FDD + FDD, or FDD + TDD mode, and when the first switch inside the 4G power amplifier 130 is closed, for example, the first switch inside the low frequency power amplifier 131 is closed, and the second switch inside the medium/high frequency power amplifier 132 is closed, the electronic device searches for the voltage required for the 4G power amplifier 130 to operate at the current time, for example, 2.5V, and the voltage required for the 5G power amplifier 140 to operate, for example, 2.8V, and at this time, the power management module 120 outputs the APT voltage of 2.8V to simultaneously power the 4G power amplifier and the 5G power amplifier.
According to the power supply method of the radio frequency circuit, only one power supply management module is arranged in the radio frequency circuit, and under the condition that the electronic equipment independently works in a 4G network mode or a 5G network mode, the power supply management module can provide voltage required by the working of a 4G power amplifier or a 5G power amplifier; under the condition that the electronic equipment simultaneously works in a 4G network mode and a 5G network mode, and both the 4G network mode and the 5G network mode are in a time division duplex mode, the power supply management module can provide voltage required by the 4G power amplifier to work in a first time period and provide voltage required by the 5G power amplifier to work in a second time period; and under the condition that the electronic equipment simultaneously works in the 4G network mode and the 5G network mode, and at least one of the 4G network mode and the 5G network mode is the frequency division duplex mode, the power supply management module simultaneously provides the voltage required by the 4G power amplifier and the 5G power amplifier to work at the target voltage. That is, only through setting up a power management module, alright realize independent 4G work, independent network deployment (independent 5G work) and the power supply under the different scenes of dependent network deployment (4G and 5G simultaneous working), simultaneously, because it has saved a power management module compared in prior art, can save PCB's overall arrangement space, provide more overall arrangements and optimization space for other modules, for example can increase battery capacity, increase camera quantity, can arrange bigger sound chamber etc. in order to further promote user experience and feel.
The embodiment of the present application further relates to a radio frequency circuit 10, as shown in fig. 1, including a transceiver 110, a power management module 120, a 4G power amplifier 130, and a 5G power amplifier 140.
The input terminal of the power management module 120 is connected to the transmitting terminal of the transceiver 110, the input terminal of the 4G power amplifier 130 is connected to the output terminal of the power management module 120, and the input terminal of the 5G power amplifier 140 is connected to the output terminal of the power management module 140.
The 4G power amplifier 130 may include a 4G low-frequency power amplifier 131 and a 4G medium-high-frequency power amplifier 132, so as to implement transceiving of signals in each frequency band of 4G.
The above 4G power amplifier 130 is internally provided with a first switch, and the above 5G power amplifier 140 is internally provided with a second switch, where the radio frequency circuit 10 further includes a processing unit.
For example, when the electronic device operates in the 4G network mode independently and transmits a signal, the processing unit controls the first switch inside the 4G power amplifier 130 to be closed, that is, the 4G power amplifier 130 is in an operating state, and the power management module 120 provides a voltage required for the operation of the 4G power amplifier 130.
For another example, when the electronic device operates in the 5G network mode independently and transmits a signal, the processing unit controls the second switch inside the 5G power amplifier 140 to be closed, that is, the 5G power amplifier 140 is in an operating state, and the power management module 120 supplies power to the 5G power amplifier 140.
For another example, in a case where the electronic device operates in the 4G network mode and the 5G network mode simultaneously, and both the 4G network mode and the 5G network mode are the time division duplex mode, the power management module 120 provides the voltage required for the 4G power amplifier 130 to operate during the first time period, and provides the voltage required for the 5G power amplifier 150 to operate during the second time period. For example, when the 4G signal is transmitted, the processing unit controls a first switch inside the 4G power amplifier to be closed, a second switch inside the 5G power amplifier to be opened, and the power management module 130 supplies power to the 4G power amplifier. For another example, when the 5G signal is transmitted, the processing unit controls the first switch inside the 4G power amplifier 130 to be opened, the second switch inside the 5G power amplifier 140 to be closed, and the power management module 120 supplies power to the 5G power amplifier 140.
Also for example, in a case where the electronic device is simultaneously operating in the 4G network mode and the 5G network mode, and at least one of the 4G network mode and the 5G network mode is the time division duplex mode, the power management module 120 simultaneously provides the voltages required for the 4G power amplifier 130 and the 5G power amplifier 140 to operate at the target voltages.
