Description

Radio frequency device, control method thereof and terminal equipment

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a radio frequency device, a control method thereof and terminal equipment.

Background

With the development of mobile communication technology, fourth generation mobile communication technology (hereinafter referred to as 4G technology) has failed to meet the increasing use demand, and therefore fifth generation mobile communication technology (hereinafter referred to as 5G technology) has come up.

Currently, in a period when the 4G technology and the 5G technology coexist, in order to be compatible with the 4G technology and the 5G technology, some terminal devices may support two Subscriber Identification Module (SIM) cards, one SIM card being a SIM card supporting the 4G technology (hereinafter, referred to as a 4G card), and the other SIM card being a SIM card supporting the 5G technology (hereinafter, referred to as a 5G card). For the terminal equipment, two independent radio frequency systems can be arranged in the terminal equipment, wherein one radio frequency system is a radio frequency system corresponding to a 4G card, and the other radio frequency system is a radio frequency system corresponding to a 5G card.

However, since the frequency bands supported by the 4G technology overlap with some frequency bands supported by the 5G technology, when the 4G card and the 5G card operate simultaneously, since a signal transmitted by the radio frequency system corresponding to one card is received by the radio frequency system corresponding to another card, and the strength of the signal received by the radio frequency system corresponding to the other card is usually relatively high, the radio frequency device in the radio frequency system corresponding to the other card is damaged.

In addition, in the embodiment of the present invention, the first control unit and the second control unit may be an integrated control unit, or may be two independent control units.

The embodiment of the present invention is described by taking an example that one rf system is in a state of transmitting a signal, or another rf system is turned off when the transmission power of the transmission signal is large (for example, greater than or equal to a power threshold value).

The radio frequency device, the control method thereof, and the terminal device provided in the embodiments of the present invention are described below by taking an example that a control unit, that is, a radio frequency system is in a state of transmitting a signal, or the control unit turns off another radio frequency system when the transmission power of the transmitted signal is large.

First, an exemplary radio frequency device provided by an embodiment of the present invention is described with reference to the drawings.

As shown in fig. 1, an embodiment of the present invention provides an rf device 20, where the rf device 20 may include a first rf transceiver circuit 201, a second rf transceiver circuit 202, and a control unit 203 connected to the first rf transceiver circuit 201 and the second rf transceiver circuit 202. The control unit 203 may be configured to turn off the second rf transceiver circuit 202 when the first rf transceiver circuit 201 satisfies the first condition. Wherein the first condition may be: is in a state of transmitting a signal, or the transmission power of the transmission signal is greater than or equal to a power threshold. Specifically, the control unit 203 may be configured to turn off the second rf transceiver circuit 202 when the first rf transceiver circuit 201 is in a state of transmitting a signal, or when a transmission power of the signal transmitted by the first rf transceiver circuit 201 is greater than or equal to a power threshold.

Optionally, in this embodiment of the present invention, the first rf transceiver circuit 201 may be a 4G rf transceiver circuit, and the second rf transceiver circuit 202 may be a 5G rf transceiver circuit. Alternatively, the first rf transceiver circuit 201 may be a 5G rf transceiver circuit, and the second rf transceiver circuit 202 may be a 4G rf transceiver circuit.

In the embodiment of the invention, the transmitting power of the signal transmitted by the first radio frequency transmitting and receiving circuit can be obtained by measuring the power of the signal transmitted by the first radio frequency transmitting and receiving circuit.

It should be noted that the power threshold will be described in detail in the following embodiments, and will not be described herein.

Optionally, in this embodiment of the present invention, as shown in fig. 1, the radio frequency device 20 may further include a processor 204 connected to the first radio frequency transceiver circuit 201 and the second radio frequency transceiver circuit 202. The processor 204 may be configured to control the first rf transceiver circuit 201 to transmit and receive signals, and control the second rf transceiver circuit 202 to transmit and receive signals.

Optionally, in this embodiment of the present invention, the processor 204 may be a Central Processing Unit (CPU), an Application Processor (AP), or any other possible processor. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

In the embodiment of the invention, the control unit in the terminal equipment can close the second radio frequency transceiver circuit in the terminal equipment when the first radio frequency transceiver circuit in the terminal equipment is in a signal transmitting state or the transmitting power of the signal transmitted by the first radio frequency transceiver circuit is greater than or equal to the power threshold, so that the second radio frequency transceiver circuit does not work when the first radio frequency transceiver circuit transmits the signal, the second radio frequency transceiver circuit can be ensured not to receive the signal transmitted by the first radio frequency transceiver circuit, and further, the damage of a radio frequency device in the second radio frequency transceiver circuit can be avoided.

Optionally, in an embodiment of the present invention, in combination with fig. 1, as shown in fig. 2, the first rf transceiver circuit 201 may include a first modem 111.

Optionally, in an embodiment of the present invention, in a possible implementation manner, when the first condition is a state of transmitting a signal (that is, the first rf transceiver circuit satisfies the first condition, that is, the first rf transceiver circuit is in a state of transmitting a signal), the control unit 203 shown in fig. 1 may specifically be the first modem 111 shown in fig. 2, or a module capable of implementing a control function in the first modem 111 in the embodiment of the present invention, or the like. When the control unit 203 is the first modem 111, as shown in fig. 2, the first modem 111 may be configured to output the first control signal to the second rf transceiver circuit 203 to turn off the second rf transceiver circuit 202 when the first rf transceiver circuit 201 is in a state of transmitting a signal.

Optionally, in this embodiment of the present invention, the first control signal may be a low-level signal, a high-level signal, or any other control signal that can control the second radio frequency transceiver to turn off, which may be determined specifically according to actual use requirements, and this embodiment of the present invention is not limited.

One possible implementation of the above is exemplified below with reference to fig. 2.

In the embodiment of the present invention, as shown in fig. 2, after the first rf transceiver circuit 201 is in a state of transmitting a signal, that is, after the first rf transceiver circuit 201 transmits a signal, the first modem 111 in the first rf transceiver circuit 201 may output a first control signal (for example, a low level signal) to the second rf transceiver circuit 202 to turn off the second rf transceiver circuit 202, so that the second rf transceiver circuit 202 cannot receive the signal transmitted by the first rf transceiver circuit 201, and further, the signal transmitted by the first rf transceiver circuit 201 can be prevented from entering the second rf transceiver circuit 202. Therefore, the radio frequency device in the second radio frequency transceiver circuit can be prevented from being damaged, and the service life of the radio frequency device is prolonged.

In the embodiment of the invention, because the modem can control the radio frequency transceiver circuit to transmit signals, the first modem is used as the control unit, so that when the first radio frequency transceiver circuit transmits signals, the first modem can control the second radio frequency transceiver circuit to be closed. Namely, the first modem can be used as a control unit to accurately control the second radio frequency transceiver circuit to be closed.

Optionally, in an embodiment of the present invention, in another possible implementation manner, when the first condition is that the transmission power of the transmission signal is greater than or equal to a power threshold (that is, the first radio frequency transceiver circuit meets the first condition, that is, the transmission power of the transmission signal of the first radio frequency transceiver circuit is greater than or equal to the power threshold), as shown in fig. 1, the control unit 203 may be specifically configured to, when the transmission power of the transmission signal of the first radio frequency transceiver circuit 201 is greater than or equal to the power threshold, output a second control signal to the second radio frequency transceiver circuit 202, and turn off the second radio frequency transceiver circuit 202.

In the embodiment of the invention, when the transmitting power of the signal transmitted by the first radio frequency transceiver circuit is less than the power threshold, the transmitting signal does not influence the normal work of the second radio frequency transceiver circuit, so that the control unit closes the second radio frequency transceiver circuit when the transmitting power of the signal transmitted by the first radio frequency transceiver circuit is greater than or equal to the power threshold, the second radio frequency transceiver circuit can work normally when the transmitting power of the signal transmitted by the first radio frequency transceiver circuit is smaller, and the device of the second radio frequency transceiver circuit can be prevented from being damaged when the transmitting power of the signal transmitted by the first radio frequency transceiver circuit is larger, thereby improving the working performance of the radio frequency device.

Optionally, in an embodiment of the present invention, in another possible implementation manner described above, with reference to fig. 1, as shown in fig. 3, when the first condition is that the transmission power of the transmission signal is greater than or equal to a power threshold, the control unit 203 may include a target processing module 2031, and the target processing module 2031 is connected to the first radio frequency transceiver circuit 201 and the second radio frequency transceiver circuit 202. The target processing module 2031 may be configured to process a signal transmitted by the first rf transceiver circuit 201, compare a voltage value of the processed signal with a voltage threshold, and turn off the second rf transceiver circuit 202 by outputting a comparison result to the second rf transceiver circuit 202.

It is understood that, in the embodiment of the present invention, the comparison result may be a second control signal output by the control unit.

Optionally, in this embodiment of the present invention, the voltage threshold may be determined according to the power threshold. Specifically, the voltage threshold may be a rated voltage value corresponding to the power threshold. It can be understood that, when the power value of the signal transmitted by the first rf transceiver circuit is the power threshold, the voltage value corresponding to the transmitted signal is the voltage threshold.

Optionally, in this embodiment of the present invention, the comparison result may be "0" (indicating a low level signal) or "1" (indicating a high level signal). Specifically, the determination may be performed according to a control instruction of a radio frequency device (for example, a radio frequency device that needs to be turned off by the control unit) in the second radio frequency transceiver circuit, which is not limited in the embodiment of the present invention.

It should be noted that the control commands for different models of rf devices may be different. For example, for some rf devices (hereinafter rf device a), "0", i.e., a low level signal, may be used to turn off rf device a; a "1", i.e. a high level signal, may be used to turn on the rf device a. For some rf devices (hereinafter referred to as rf device B), "1", i.e. a high level signal, may be used to turn off rf device B and "0", i.e. a low level signal, may be used to turn on rf device B.

In the embodiment of the invention, the target processing module can convert the signal transmitted by the first radio frequency transceiver circuit into the control signal for controlling the second radio frequency transceiver circuit after processing and comparing the signal, so that the second radio frequency transceiver circuit can be closed under the condition that the transmitting power of the signal transmitted by the first radio frequency transceiver circuit is greater than or equal to the power threshold value. And the second radio frequency transceiver circuit does not need to be closed under the condition that the transmitting power of the signal transmitted by the first radio frequency transceiver circuit is smaller than the power threshold, so that the control unit can flexibly control the second radio frequency transceiver circuit to be closed according to the transmitting power of the signal transmitted by the first radio frequency transceiver circuit.

Optionally, in an embodiment of the present invention, in another possible implementation manner described above, with reference to fig. 3, as shown in fig. 4, the control unit 203 may further include a logic gate 2032, where the logic gate 2032 is located between the target processing module 2031 and the second rf transceiver circuit 202. The target processing module 2031 may be further configured to output the comparison result to the logic gate circuit 2032; the logic gate 2032 may be configured to convert the comparison result and output the converted comparison result to the second rf transceiver circuit 202, so as to turn off the second rf transceiver circuit 202.

It is understood that, in the embodiment of the present invention, the converted comparison result may be the second control signal.

Optionally, in the embodiment of the present invention, the logic gate circuit may be any one, two, or a combination of two or more of an and gate, a not gate, and an or gate, and may be determined according to actual use requirements.

It should be noted that, since the control commands of different types of rf devices are different, and the comparison result output by the comparison device (for example, the comparator 2031c described below) may also be different when the voltage values input at the two signal terminals of the comparison device are different, in a case where the result output by the comparison device is opposite to the control command of the rf device in the second rf transceiver circuit, the control unit may further include a logic gate circuit, and the logic gate circuit may be configured to convert the comparison result of the comparison device into a control command corresponding to the rf device. For example, when the voltage threshold is input at the "+" terminal of the comparison device, the voltage value of the signal is input at the "-" terminal of the comparison device, and the turn-off command in the second rf transceiver circuit is "0", the comparison device needs to output the second control signal to turn off the second rf transceiver circuit when the voltage value of the signal is greater than or equal to the voltage threshold, that is, the transmission power of the transmission signal is greater than or equal to the power threshold, however, in this case, since the comparison result of the comparison device is "1", in this case, the comparison result "1" may be converted into "0" by setting a logic gate circuit in the control unit, and then "0" is output to the second rf transceiver circuit as the second control signal to turn off the second rf transceiver circuit.

In the embodiment of the invention, the comparison result output by the target processing module and the control instruction of the radio frequency device in the second radio frequency transceiver circuit may be opposite, and the logic gate circuit in the control unit can convert the comparison result into the result which is the same as the control instruction of the second radio frequency transceiver circuit, so that the target processing module can be ensured to accurately close the second radio frequency transceiver circuit.

Optionally, in an embodiment of the present invention, in another possible implementation manner described above, with reference to fig. 4, as shown in fig. 5, the target processing module 2031 may include a power divider 2031a, a detector circuit 2031b connected to the power divider 2031a, and a comparator 2031c connected to the detector circuit 2031 b. The power divider 2031a is connected to the first rf transceiver 201, and the comparator 2031c is connected to the logic gate 2032.

In this embodiment of the present invention, the power divider and the detector circuit may be configured to process a signal transmitted by the first rf transceiver circuit, and the comparator may be configured to compare a voltage value and a voltage threshold of the processed signal, and output a comparison result to the second rf transceiver circuit to turn off the second rf transceiver circuit.

Another possible implementation of the above is described below with reference to fig. 5.

In the embodiment of the present invention, as shown in fig. 5, after the first rf transceiver circuit 201 transmits a signal, a device (for example, a coupler described below) in the first rf transceiver circuit may output an rf signal to the power divider 2031a, after the power divider 2031a receives the rf signal, the rf signal may be divided into a first branch signal and a second branch signal, then the power divider 2031a outputs the first branch signal to the first rf transceiver circuit 201 and outputs the second branch signal to the detector circuit 2031b, after the detector circuit 2031b receives the second branch signal, the second branch signal may be converted into a first dc signal, then the detector circuit 2031b may output the first dc signal to the comparator 2031c, after the comparator 2031c receives the first dc signal, a first dc voltage corresponding to the first dc signal may be compared with a voltage threshold, under the condition that the first direct-current voltage is greater than the voltage threshold, the comparator 2031c may output a second control signal (e.g., a low level signal) to the second rf transceiver circuit 202 to turn off the second rf transceiver circuit 202, so that the second rf transceiver circuit 202 cannot receive the signal transmitted by the first rf transceiver circuit 201, thereby preventing the rf devices in the second rf transceiver circuit from being damaged and prolonging the service life of the rf devices.

In the embodiment of the present invention, the power divider and the detection circuit in the target processing module may process the signal transmitted by the first rf transceiver circuit, and the comparator may compare the voltage of the processed signal with a voltage threshold, and then the comparator may output the comparison result to the second rf transceiver circuit to turn off the second rf transceiver circuit, so that the second rf transceiver circuit may be turned off when the transmission power of the signal transmitted by the first rf transceiver circuit is greater than or equal to the power threshold. And the second radio frequency transceiver circuit does not need to be closed under the condition that the transmitting power of the signal transmitted by the first radio frequency transceiver circuit is smaller than the power threshold, so that the control unit can flexibly control the second radio frequency transceiver circuit to be closed according to the transmitting power of the signal transmitted by the first radio frequency transceiver circuit.

Optionally, in this embodiment of the present invention, in combination with fig. 1, as shown in fig. 6, the first radio frequency transceiver circuit 201 may include a first signal processing module 11 connected to the processor 203, a first transmitting branch 12 and a first receiving branch 13 connected to the first signal processing module 11, a first radio frequency switch 14 connected to the first transmitting branch 12 and the first receiving branch 13, a first coupler 15 connected to the first radio frequency switch 14, and a first antenna 16 connected to the first coupler 15. The second rf transceiver circuit 202 may include a second signal processing module 21 connected to the processor 204, a second transmitting branch 22 and a second receiving branch 23 connected to the second signal processing module 21, a second rf switch 24 connected to the second transmitting branch 22 and the second receiving branch 23, a second coupler 25 connected to the second rf switch 24, and a second antenna 26 connected to the second coupler 25.

It should be noted that, in the embodiment of the present invention, when the control unit is a first modem, the first modem is connected to a second receiving branch in a second rf transceiver circuit. Or, when the control unit includes the target processing module, the power divider is connected to the first coupler in the first rf transceiving circuit, and the comparator is connected to the second receiving branch in the second rf transceiving branch. Or, when the control unit includes the target processing module and the logic gate circuit, the power divider is connected to the first coupler in the first rf transceiver circuit, and the logic gate circuit is connected to the second receiving branch in the second rf transceiver circuit.

Optionally, in this embodiment of the present invention, as shown in fig. 6, the control unit 203 may be specifically configured to close the second receiving branch 23 when the first rf transceiver circuit 201 meets a first condition (that is, the first rf transceiver circuit is in a state of transmitting a signal, or a transmission power of the transmitted signal is greater than or equal to a power threshold).

In the embodiment of the invention, the control unit can close the second receiving branch in the second radio frequency transceiver circuit under the condition that the first radio frequency transceiver circuit meets the first condition, so that the second receiving branch can not receive the signal transmitted by the first radio frequency transceiver circuit, the radio frequency device in the second receiving branch can be prevented from being damaged, and the service life of the radio frequency device can be prolonged.

Furthermore, the control unit only closes the second receiving branch in the second radio frequency transceiver circuit when the first radio frequency transceiver circuit meets the first condition, so that the second transmitting branch in the second radio frequency transceiver circuit can still work normally.

The second transmitting branch 22 may include a second power amplifier 221 connected to the second signal processing module 21, a third filter 222 connected to the second power amplifier 221, and the third filter 222 is connected to the second rf switch 24.

Optionally, in this embodiment of the present invention, the control unit 203 may be specifically configured to turn off the second low noise amplifier 232 in the second receiving branch 23 when the first rf transceiver circuit 201 meets the first condition (that is, the first rf transceiver circuit is in a state of transmitting a signal, or the transmission power of the transmitted signal is greater than or equal to a power threshold).

In addition, in the embodiment of the present invention, when the control unit is a first modem, the first modem is connected to a low noise amplifier in a second receiving branch of the second radio frequency transceiver circuit. Or, when the control unit includes the target processing module, the power divider is connected to the first coupler in the first rf transceiver circuit, and the comparator is connected to the low noise amplifier in the second receiving branch in the second rf transceiver circuit. Or, when the control unit includes the target processing module and the logic gate circuit, the power divider is connected to the first coupler in the first rf transceiver circuit, and the logic gate circuit is connected to the low noise amplifier in the second receiving branch in the second rf transceiver circuit.

Optionally, in this embodiment of the present invention, the power threshold may be a sum of a maximum input power of a radio frequency device (e.g., a low noise amplifier) in the second radio frequency transceiver circuit and an isolation degree of the antenna, where the isolation degree of the antenna is an isolation degree between the first antenna and the second antenna. For example, assuming that the maximum input power of the low noise amplifier is 10dBm and the isolation between the first antenna and the second antenna is 10dBm, the power threshold may be 10dBm +10 dBm-20 dBm.

In the embodiment of the present invention, on one hand, when the first radio frequency transceiver circuit meets the first condition, the control unit may turn off the second low noise amplifier in the second radio frequency transceiver circuit, so that it may be ensured that the second low noise amplifier cannot receive the signal transmitted by the first radio frequency transceiver circuit. On the other hand, since the power of the signal transmitted by the first rf transceiver circuit (i.e., the transmission power of the first rf transceiver circuit) is usually relatively high, turning off the second low noise amplifier can prevent the second low noise amplifier from receiving the signal transmitted by the first rf transceiver circuit, thereby preventing the second low noise amplifier from being damaged and further prolonging the service life of the second low noise amplifier.

It should be noted that, in the embodiment of the present invention, the description of the above embodiment and each of the drawings are exemplified by a control unit controlling a radio frequency system. In practical implementation, two control units may be used to control two rf systems respectively, or one control unit may be used to control two rf systems. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

As shown in fig. 8, an embodiment of the present invention further provides a control method, which is applied to a radio frequency device, where the radio frequency device may be the radio frequency device 20 described in the foregoing embodiment, and the method may include the following steps S501 to S502:

s501, the radio frequency device detects whether a first radio frequency transceiver circuit in the radio frequency device meets a first condition.

Wherein, the first condition may be: is in a state of transmitting a signal, or the transmission power of the transmission signal is greater than or equal to a power threshold.

In the embodiment of the present invention, the radio frequency device may determine whether to turn off the second radio frequency transceiver circuit by detecting whether the first radio frequency transceiver circuit in the radio frequency device is in a state of transmitting a signal, or whether the transmission power of the signal transmitted by the first radio frequency transceiver circuit is greater than or equal to a power threshold.

Optionally, in the embodiment of the present invention, the first rf transceiver circuit may be a 4G rf transceiver circuit, and may also be a 5G rf transceiver circuit.

It should be noted that, in the embodiment of the present invention, if the radio frequency device detects that the first radio frequency transceiver circuit satisfies the first condition, the radio frequency device may continue to execute the following S502; if the rf device detects that the first rf transceiver circuit does not satisfy the first condition, the rf device may return to S501 for continuing the execution.

S502, the radio frequency device closes a second radio frequency transceiver circuit in the radio frequency device.

In the embodiment of the present invention, if the radio frequency device detects that the first radio frequency transceiver circuit is in a state of transmitting a signal, or the transmission power of the transmitted signal is greater than or equal to the power threshold (that is, the first radio frequency transceiver circuit satisfies the first condition), the radio frequency device may turn off the second radio frequency transceiver circuit.

Optionally, in the embodiment of the present invention, the second rf transceiver circuit may be a 4G rf transceiver circuit, and may also be a 5G rf transceiver circuit. Specifically, when the first rf transceiver circuit is a 4G rf transceiver circuit, the second rf transceiver circuit may be a 5G rf transceiver circuit. Or, when the first rf transceiver circuit is a 5G rf transceiver circuit, the second rf transceiver circuit may be a 4G rf transceiver circuit.

Optionally, in the embodiment of the present invention, the step S502 may be specifically implemented by the step S502a described below.

S502a, the rf device turns off the receiving branch of the second rf transceiver circuit.

It can be understood that, in the embodiment of the present invention, in a case that the first rf transceiver circuit in the rf device satisfies the first condition, the rf device may turn off the receiving branch in the second rf transceiver circuit.

In the embodiment of the invention, because the signal transmitted by the first radio frequency transceiver circuit has less influence on the transmitting branch in the second radio frequency transceiver circuit, the radio frequency device closes the receiving branch in the second radio frequency transceiver circuit, thereby not only ensuring that the transmitting branch can normally work when the first radio frequency transceiver circuit transmits the signal, but also preventing the device of the receiving branch from being damaged when the first radio frequency transceiver circuit transmits the signal, and further improving the working performance of the radio frequency device.

Optionally, in the embodiment of the present invention, the step S502a may be specifically implemented by the step S502a1 described below.

S502a1, the rf device turns off the low noise amplifier in the receiving branch.

It can be understood that, in the embodiment of the present invention, in the case that the first rf transceiver circuit in the rf device satisfies the first condition, the rf device may turn off the low noise amplifier in the receiving branch of the second rf transceiver circuit.

In the embodiment of the invention, the signal transmitted by the first radio frequency transceiver circuit has larger influence on the low noise amplifier in the receiving branch circuit in the second radio frequency transceiver circuit and has smaller influence on other devices in the second radio frequency transceiver circuit, so that the radio frequency device can close the low noise amplifier, and can prevent the devices in the receiving branch circuit from being damaged.

Optionally, in the embodiment of the present invention, the foregoing S502 may specifically have two possible implementation manners. In a possible implementation manner, the radio frequency device may directly turn off the second radio frequency transceiver circuit when the first radio frequency transceiver circuit is in a state of transmitting a signal. In another possible implementation manner, in the case that the first radio frequency transceiver circuit transmits a signal, the radio frequency device may first determine whether the transmission power of the signal transmitted by the first radio frequency transceiver circuit is greater than or equal to a power threshold, and only when the transmission power of the signal transmitted by the first radio frequency transceiver circuit is greater than or equal to the power threshold, the radio frequency device turns off the second radio frequency transceiver circuit.

For example, in one possible implementation manner in the embodiment of the present invention, in a case that the first condition is a state of transmitting a signal, the above S502 may be specifically implemented by the following S503.

And S503, under the condition that the first radio frequency transceiver circuit is in the state of transmitting signals, the radio frequency device outputs a first control signal to the second radio frequency transceiver circuit to close the second radio frequency transceiver circuit.

In the embodiment of the invention, the radio frequency device can convert the signal transmitted by the first radio frequency transceiver circuit into the control signal for controlling the second radio frequency transceiver circuit to be closed, so that the second radio frequency transceiver circuit can be closed under the condition that the first radio frequency transceiver circuit is in the state of transmitting the signal.

For example, in another possible implementation manner in the embodiment of the present invention, in a case that the first condition is that the transmission power of the transmission signal is greater than or equal to the power threshold, the step S502 may be specifically implemented by the step S504 described below.

S504, under the condition that the transmitting power of the signal transmitted by the first radio frequency transceiver circuit is greater than or equal to the power threshold, the radio frequency device outputs a second control signal to the second radio frequency transceiver circuit, and the second radio frequency transceiver circuit is closed.

In the embodiment of the invention, the radio frequency device can convert the signal transmitted by the first radio frequency transceiver circuit into the control signal for controlling the second radio frequency transceiver circuit to be closed, so that the second radio frequency transceiver circuit can be closed under the condition that the transmission power of the signal transmitted by the first radio frequency transceiver circuit is greater than or equal to the power threshold value.
