The embodiment of the invention also provides a control method which is applied to electronic equipment, and the electronic equipment comprises the radio frequency circuit provided by the embodiment of the invention. The control method of the embodiment of the present invention is explained below.
Referring to fig. 3, fig. 3 is a flowchart of a control method according to an embodiment of the present invention. As shown in fig. 3, the control method may include the steps of:
301, controlling the conducting state of the switch module according to the working frequency band of the radio frequency circuit.
The switch module is used for flexibly switching the power supply of the first radio frequency module and the power supply of the second radio frequency module, and the radio frequency module is in a working state only under the condition that the power supply supplies power.
The working frequency band of the radio frequency circuit is the working frequency band corresponding to the signal to be transmitted and received by the radio frequency circuit. Therefore, in this embodiment, the electronic device may determine the states of the first radio frequency module and the second radio frequency module in the target time according to the working frequency band of the radio frequency circuit, where the radio frequency circuit receives and transmits the signal of the working frequency band in the target time. And then, controlling the conduction state of the switch module according to the states of the first radio frequency module and the second radio frequency module in the target time, so that the radio frequency circuit receives and transmits the signals of the working frequency band in the target time.
In a specific implementation, the operating frequency band of the radio frequency circuit may include the following conditions:
in case one, the working frequency band of the radio frequency circuit is the first frequency band.
In this case, in the target time, the radio frequency circuit only receives and transmits signals of the first frequency band, and the first radio frequency module is in a working state and needs to be powered by a power supply; the second radio frequency module is in a non-working state and does not need to be powered by a power supply.
Therefore, for the first case, in the first embodiment, the electronic device may control the third contact to be conductive with the first contact. Therefore, the LDO power supply can supply power to the first radio frequency module, so that the first radio frequency module receives and transmits signals of a first frequency band.
In the second embodiment, optionally, the controlling the on state of the switch module may specifically be as follows: and controlling the third contact to be conducted with the second contact. Therefore, the target power supply can supply power to the first radio frequency module, so that the first radio frequency module receives and transmits signals of the first frequency band.
As can be seen from the above, the first embodiment differs from the second embodiment in that: the power supply of the first rf module in the first embodiment is different from the power supply of the first rf module in the second embodiment. Specifically, the power supply of the first rf module in the first embodiment is the LDO power supply, and the power supply of the first rf module in the second embodiment is the target power supply.
As can be seen from the foregoing, the output voltage of the target power supply can be adjusted in real time according to the output power of the PA, and the output voltage of the LDO power supply is relatively fixed and cannot be adjusted in real time. Therefore, compared with the method that the LDO power supply is adopted to supply power for the first radio frequency module, the target power supply is adopted to supply power for the first radio frequency module, and the best working efficiency of the PA can be guaranteed.
And in the second case, the working frequency band of the radio frequency circuit is the second frequency band.
In this case, in the target time, the radio frequency circuit only receives and transmits signals of the second frequency band, the first radio frequency module is in a non-working state, and a power supply is not needed for supplying power; the second radio frequency module is in a working state and needs to be powered by a power supply.
Therefore, for the second case, in the third embodiment, the electronic device may control the fourth contact to be conductive with the first contact. Therefore, the LDO power supply can supply power to the second radio frequency module, so that the second radio frequency module receives and transmits signals of a second frequency band.
In the second embodiment, optionally, the controlling the on state of the switch module may specifically be as follows: and controlling the fourth contact to be conducted with the second contact. Therefore, the target power supply can supply power to the second radio frequency module, so that the second radio frequency module receives and transmits signals of the second frequency band.
As is apparent from the above description, the third embodiment differs from the fourth embodiment in that: the power supply of the first rf module in the third embodiment is different from the power supply of the first rf module in the fourth embodiment. Specifically, the power supply of the second rf module in the third embodiment is the LDO power supply, and the power supply of the second rf module in the fourth embodiment is the target power supply.
As can be seen from the foregoing, the output voltage of the target power supply can be adjusted in real time according to the output power of the PA, and the output voltage of the LDO power supply is relatively fixed and cannot be adjusted in real time. Therefore, compared with the method that the LDO power supply is adopted to supply power for the second radio frequency module, the target power supply is adopted to supply power for the second radio frequency module, and the best working efficiency of the PA can be guaranteed.
And in the third case, the working frequency band of the radio frequency circuit comprises the first frequency band and the second frequency band.
In this case, in the target time, the radio frequency circuit receives and transmits signals of the first frequency band and the second frequency band, and the first radio frequency module and the second radio frequency module are both in a working state and need to be powered by the power supply.
For the case three, in the fifth embodiment, optionally, the controlling the conduction state of the switch module may specifically be as follows:
and controlling the conduction state of each contact in the switch module according to the comparison result of the maximum frequency values of the first frequency band and the second frequency band.
In a specific implementation, the electronic device may control the first contact and the first target contact, and control the second contact to connect to the second target contact, where the first target contact is a contact electrically connected to the radio frequency module for transceiving a signal in a frequency band with a smaller maximum frequency value, and the second target contact is a contact electrically connected to the radio frequency module for transceiving a signal in a frequency band with a larger maximum frequency value. Therefore, the LDO power supply supplies power for the radio frequency module used for receiving and transmitting the signals of the frequency band with the smaller maximum frequency value, and the target power supply supplies power for the radio frequency module used for receiving and transmitting the signals of the frequency band with the larger maximum frequency value, so that the efficiency of the radio frequency module used for receiving and transmitting the signals of the frequency band with the larger maximum frequency value can be ensured.
Further, the controlling the conduction state of the switch module according to the comparison result of the maximum frequency values of the first frequency band and the second frequency band includes at least one of the following:
when the maximum frequency value of the first frequency band is greater than or equal to the maximum frequency value of the second frequency band, controlling the first contact to be communicated with the fourth contact, and controlling the second contact to be communicated with the third contact;
and under the condition that the maximum frequency value of the second frequency band is greater than the maximum frequency value of the first frequency band, controlling the first contact to be communicated with the third contact, and controlling the second contact to be communicated with the fourth contact.
And under the condition that the maximum frequency value of the first frequency band is greater than or equal to the maximum frequency value of the second frequency band, the power consumption of the first radio frequency module is higher than that of the second radio frequency module, and the efficiency of the first radio frequency module is preferentially ensured, so that the electronic equipment can control the target power supply to supply power to the first radio frequency module and control the LDO power supply to supply power to the second radio frequency module.
Under the condition that the maximum frequency value of the second frequency band is larger than the maximum frequency value of the first frequency band, the power consumption of the second radio frequency module is higher than that of the first radio frequency module, and the efficiency of the second radio frequency module is preferentially ensured.
As can be seen from the foregoing, in some implementation manners, the first frequency band may be a frequency band in the first communication system, and the second frequency band may be a frequency band in the second communication system. For this implementation manner, optionally, the controlling the conduction state of the switch module may specifically be represented as:
and controlling the conduction state of each contact in the switch module according to the version levels of the first communication system and the second communication system.
In specific implementation, the electronic device may control the first contact and a fifth target contact, and control the second contact to connect with a sixth target contact, where the fifth target contact is a contact electrically connected to a radio frequency module configured to receive and transmit a signal of a low-version-level communication system, and the sixth target contact is a contact electrically connected to a radio frequency module configured to receive and transmit a signal of a high-version-level communication system. Therefore, the LDO power supply supplies power for the radio frequency module used for receiving and transmitting the signals of the communication system at the low version level, and the target power supply supplies power for the radio frequency module used for receiving and transmitting the signals of the communication system at the high version level, so that the efficiency of the radio frequency module used for receiving and transmitting the signals of the communication system at the high version level can be ensured.
Further, the controlling the conduction state of the switch module according to the version levels of the first communication system and the second communication system includes at least one of the following:
under the condition that the version level of the first communication system is higher than that of the second communication system, controlling the first contact and the fourth contact to be conducted, and controlling the second contact and the third contact to be conducted;
and under the condition that the version level of the second communication system is higher than that of the first communication system, controlling the first contact and the third contact to be conducted, and controlling the second contact and the fourth contact to be conducted.
Under the condition that the version level of the first communication system is higher than that of the second communication system, the power consumption of the first radio frequency module is higher than that of the second radio frequency module, and the efficiency of the first radio frequency module is preferentially ensured, so that the electronic equipment can control the target power supply to supply power to the first radio frequency module and control the LDO power supply to supply power to the second radio frequency module.
And under the condition that the version level of the second communication system is higher than that of the first communication system, the power consumption of the second radio frequency module is higher than that of the first radio frequency module, and the efficiency of the second radio frequency module is preferentially ensured, so that the electronic equipment can control the target power supply to supply power to the second radio frequency module and control the LDO power supply to supply power to the first radio frequency module.
In a sixth embodiment, optionally, the controlling the on state of the switch module may specifically be as follows:
and controlling the conduction state of each contact in the switch module according to the output power of the first radio frequency module and the second radio frequency module.
In specific implementation, the electronic device may control the first contact and a third target contact, and control the fourth contact to connect to the second target contact, where the third target contact is a contact electrically connected to the radio frequency module with lower output power, and the second target contact is a contact electrically connected to the radio frequency module with higher output power. Therefore, the LDO power supply supplies power to the radio frequency module with lower output power, and the target power supply supplies power to the radio frequency module with higher output power, so that the efficiency of the radio frequency module with higher output power can be ensured.
In a first implementation manner, further, the controlling the on-state of the switch module according to the output powers of the first radio frequency module and the second radio frequency module includes at least one of:
under the condition that the output power of the first radio frequency module is higher than that of the second radio frequency module, controlling the first contact to be conducted with the fourth contact, and controlling the second contact to be conducted with the third contact;
and under the condition that the output power of the second radio frequency module is higher than that of the first radio frequency module, controlling the first contact to be conducted with the third contact, and controlling the second contact to be conducted with the fourth contact.
In a second implementation manner, further, the controlling the on-state of the switch module according to the output powers of the first radio frequency module and the second radio frequency module includes at least one of:
under the condition of P1-P2 > a, the first contact is controlled to be conducted with the fourth contact, and the second contact is controlled to be conducted with the third contact;
under the condition of P2-P1 > b, controlling the first contact to be conducted with the fourth contact, and controlling the second contact to be conducted with the third contact;
wherein P1 is the output power of the first RF module, and P2 is the output power of the second RF module. The values of a and b can be determined according to the actual debugging process, the efficiency is optimal on the premise of ensuring the radio frequency index, and different values can be set for different frequency bands and duplex modes, namely, each frequency band can be set independently.
In other cases of the second implementation, such as: when P1 is more than P2 and P1-P2 is less than or equal to a; or P2 is more than P1 and P2-P1 is less than or equal to b, and the electronic equipment control switch module keeps the previous state unchanged.
For example, after the electronic device controls the first contact and the fourth contact to be conducted and controls the second contact and the third contact to be conducted, if P1 > P2 and P1-P2 are not more than a, or P2 > P1 and P2-P1 are not more than b, or P1-P2 > a, the electronic device keeps the conducting state of the electronic module unchanged, continues to control the first contact and the fourth contact to be conducted, and controls the second contact and the third contact to be conducted. If P2-P1 > b, the electronic equipment changes the conduction state of the electronic module, controls the first contact to be conducted with the fourth contact, and controls the second contact to be conducted with the third contact.
In the sixth embodiment, the electronic device can switch the power supplies of the first radio frequency module and the second radio frequency module according to the output powers of the first radio frequency module and the second radio frequency module in real time.
The control method of the embodiment can ensure that the radio frequency circuit receives and transmits the signal of the working frequency band within the target time by controlling the conduction state of the switch module, and can reduce the power supply cost of the radio frequency circuit.
It should be noted that, various optional implementations described in the embodiments of the present invention may be implemented in combination with each other or implemented separately, and the embodiments of the present invention are not limited thereto.
For convenience of understanding, the following description will be made by taking a frequency band in which the first frequency band is a 4G communication system and a frequency band in which the second frequency band is a 5G communication system as an example.
The power supply connection state is classified into the following cases:
one, the 4G only case (i.e., the case of amplifying only the 4G signal) and the 5G only case (i.e., the case of amplifying only the 5G signal).
The working PA is connected to the APT/ET power supply, so that the working efficiency of the PA can be ensured to be optimal.
And secondly, the E-UTRA is MCG, and the NR is the double connection (E-UTRA NR dual connection with MCGusing E-UTRA and SCG using NR, EN-DC) of SCG.
1) The fixed connection mode is that, for example, a 4G PA (namely a PA for amplifying a 4G signal) is connected with an LDO power supply, and a 5G PA (namely a PA for amplifying a 5G signal) is connected with an APT/ET power supply.
