The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The radio frequency circuit, the signal transceiving method, and the electronic device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1 and 2, fig. 1 is a schematic diagram of a frequency range of a partial 5G NR frequency band, and fig. 2 is a schematic diagram of a frequency range of a WiFi frequency band. As shown in fig. 1 and fig. 2, at present, the frequencies of the N40 band of 5G and the WiFi 2.4G band are very similar, the frequencies of the N79 band of 5G and the WiFi 5G band are also very similar, but WiFi and 5G are usually not used simultaneously, that is, only one of them is in operation at the same time; when the electronic device uses the WiFi signal to surf the internet, if the distance between the electronic device and the WiFi router is short, or there are many obstacles to block the electronic device and the WiFi router, the transmission power of the power amplifier on the single WiFi signal transmission path is insufficient, which easily causes a line drop, and the reception sensitivity of the single WiFi antenna is insufficient, which also causes a line drop.
Therefore, referring to fig. 3, fig. 3 is a schematic structural diagram of a radio frequency circuit according to an embodiment of the present disclosure. As shown in fig. 3, the radio frequency circuit provided in the embodiment of the present application may include: the mobile terminal comprises a radio frequency transceiver 31, a first power amplifier 321, a second power amplifier 322, a first antenna 331 and a second antenna 332, wherein a first WiFi signal transmitting end TX1 of the radio frequency transceiver is connected with the first antenna 331 through the first power amplifier 321 to transmit WiFi signals through the first antenna 331, a first WiFi signal transmitting end TX1 and a first mobile data network signal transmitting end TX2 of the radio frequency transceiver 31 are respectively connected with a first switch 341, and the first switch 341 is further connected with the second antenna 332 through the second power amplifier 322; specifically, the first switch 341 may be configured to control the first WiFi signal transmitting terminal TX1 to communicate with the second power amplifier 322 to simultaneously transmit the WiFi signal through the first antenna 331 and the second antenna 332 when the transmission power of the first power amplifier 321 satisfies a first preset condition, and the first switch 341 may be configured to control the first mobile data network signal transmitting terminal TX2 to communicate with the second power amplifier 322 when the transmission power of the first power amplifier 321 does not satisfy the first preset condition, so as to save power consumption, and may transmit the mobile data network signal through the second antenna 332 when the WiFi network is not used. Therefore, in the embodiment of the present application, when the distance between the electronic device and the router is relatively long, or when an obstacle between the electronic device and the router affects a WiFi signal more, the second power amplifier 322 and the second antenna 332, which are originally used for transmitting a mobile data network signal, may be used to transmit the WiFi signal simultaneously, that is, the first power amplifier 321 and the second power amplifier 322 operate simultaneously, so as to enhance the transmitted WiFi signal.
In an alternative embodiment, the first switch 341 may be a single pole double throw switch.
In this embodiment of the application, the first preset condition that the transmission power of the first power amplifier 321 meets the first preset condition may specifically be: within the preset time period, the transmission power of the first power amplifier 321 continuously exceeds or is equal to a certain preset threshold, for example, the transmission power of the first power amplifier 321 within the preset time period continuously reaches its own maximum transmission power, which indicates that the distance between the electronic device and the WiFi router is long, or there are many obstacles between the electronic device and the WiFi router, even if the transmission power of the WiFi signal has maintained the maximum power, the WiFi signal is still weak, and even a line drop may occur.
The transmission power of the first power amplifier 321 does not satisfy the first preset condition and can be divided into two cases, one is that the first power amplifier 321 is still working, but the transmission power is already lower than a certain preset threshold, and then the second power amplifier 322 does not need to be used for cooperative work, so that the power consumption can be reduced after the first switch 341 is switched; the second is that the first power amplifier 321 no longer operates and no longer communicates through WiFi signals, so that the first switch 341 can allow communication through mobile data network signals after switching.
In this embodiment of the application, the frequency of the WiFi signal and the mobile data network signal output by the first mobile data network signal sending end TX1 should satisfy a second preset relationship, where the second preset relationship may be: and the difference value between the frequency of the WiFi signal and the frequency of the mobile data network signal is within a preset range, so that the second power amplifier can carry out power amplification on the WiFi signal. For example, the frequency of the WiFi signal and the frequency of the mobile data network signal have a certain overlapping frequency, or the difference between the maximum frequency of the WiFi signal and the minimum frequency of the mobile data network signal is not more than 100 MHz.
In an optional implementation manner, when the frequency band of the WiFi signal is WiFi 2.4G, the frequency band of the mobile data network signal output by the first mobile data network signal sending end is an N40 frequency band; and when the frequency band of the WiFi signal is WiFi 5G, the frequency band of the mobile data network signal output by the first mobile data network signal sending end is an N79 frequency band.
In some embodiments of the present application, the first WiFi signal receiving end RX1 of the radio frequency transceiver 31 is respectively connected to the first antenna 331 and the second antenna 332, so that when the transmission power of the first power amplifier 321 meets a first preset condition, the WiFi signal is received through the first antenna 331 and the second antenna 332 at the same time, so as to enhance the receiving capability of the WiFi signal, improve the strength of the received WiFi signal, and significantly improve the problem that the WiFi signal is weak or even the electronic device is disconnected.
In some optional embodiments of the present application, the first antenna 331 and the second antenna 332 serve as both a transmitting antenna and a receiving antenna, and in order to achieve simultaneous transmission and reception of WiFi signals, the radio frequency circuit may further include a first multiplexer 351 and a second multiplexer 352, specifically, the first WiFi signal transmitting terminal TX1 is connected to an input terminal of the first power amplifier 321, an output terminal of the first power amplifier 321 is connected to the first multiplexer 351, and the first multiplexer 351 is further connected to the first WiFi signal receiving terminal RX1 and the first antenna 331 respectively, so as to achieve simultaneous transmission and reception of WiFi signals by the first antenna 331; similarly, the first mobile data network signal transmitting terminal TX2 and the first WiFi signal transmitting terminal TX1 are respectively connected to the first switch 341, the first switch 341 is connected to the input terminal of the second power amplifier 322, the output terminal of the second power amplifier 322 is connected to the second multiplexer 352, and the second multiplexer 352 is further connected to the first WiFi signal receiving terminal RX1, the first mobile data network signal receiving terminal RX2 and the second antenna 332, so that the second antenna can receive and transmit WiFi signals and mobile data network signals.
Of course, in other alternative embodiments of the present application, if the first antenna 331 and the second antenna 332 are only used as transmitting antennas, and the receiving of the WiFi signal and the receiving of the mobile data network signal are implemented by another antenna, a multiplexer may not be used, or the first antenna 331 and the second antenna 332 do not need to transmit and receive signals simultaneously, or a multiplexer may not be used.
As shown in fig. 3, in other embodiments of the present application, the radio frequency circuit may further include: a third power amplifier 323, a fourth power amplifier 324, a third antenna 333 and a fourth antenna 334, wherein the second WiFi signal transmitting end TX3 of the radio frequency transceiver is connected to the third antenna 333 through the third power amplifier 323 to transmit WiFi signals through the third antenna 333, while the second WiFi signal transmitting end TX3 and the second mobile data network signal transmitting end TX4 of the radio frequency transceiver 31 are respectively connected to the second switch 342, and the second switch 342 is further connected to the second antenna 332 through the fourth power amplifier 324; specifically, the second switch 342 may be configured to control the second WiFi signal transmitting terminal TX3 to communicate with the fourth power amplifier 324 to simultaneously transmit WiFi signals through the second antenna 332 when the transmission power of the third power amplifier 323 satisfies the third preset condition, and the second switch 342 may be configured to control the second mobile data network signal transmitting terminal TX4 to communicate with the fourth power amplifier 324 when the transmission power of the third power amplifier 323 does not satisfy the third preset condition, so as to save power consumption, and transmit the mobile data network signal through the fourth antenna 334 when the WiFi network is not used. Therefore, in the embodiment of the present application, when the distance between the electronic device and the router is relatively long or an obstacle between the electronic device and the router affects the WiFi signal more, the fourth power amplifier 324 and the fourth antenna 334 originally used for transmitting the mobile data network signal may be used to transmit the WiFi signal, that is, the third power amplifier 323 and the fourth power amplifier operate simultaneously, so as to enhance the transmitted WiFi signal.
In an alternative embodiment, the second switch 342 may be a single pole double throw switch.
In this embodiment, the transmitting power of the third power amplifier 323 meeting the third preset condition may specifically be: within the preset time period, the transmission power of the third power amplifier 323 continues to be greater than or equal to a certain preset threshold, for example, the transmission power of the third power amplifier 323 within the preset time period continues to reach its own maximum transmission power, which indicates that the distance between the electronic device and the WiFi router is long, or there are many obstacles between the electronic device and the WiFi router, even if the transmission power of the WiFi signal has maintained the maximum power, the WiFi signal is still weak, and even a dropped connection may occur.
The transmission power of the third power amplifier 323 does not meet the first preset condition and can be divided into two cases, one is that the third power amplifier 323 still works, but the transmission power is lower than a certain preset threshold, and then the fourth power amplifier 324 does not need to be used for cooperative work, so that the power consumption can be reduced after the second switch 342 is switched; the second power amplifier 323 does not work any more and does not communicate via WiFi signals, so that the second switch 342 can allow communication via mobile data network signals after switching.
In this embodiment of the application, the frequency of the WiFi signal and the mobile data network signal output by the second mobile data network signal sending end TX4 should satisfy a second preset relationship, where the second preset relationship may be: the difference between the frequency of the WiFi signal and the frequency of the mobile data network signal is within a preset range, so as to ensure that the fourth power amplifier 324 can perform power amplification on the WiFi signal. For example, the frequency of the WiFi signal and the frequency of the mobile data network signal have a certain overlapping frequency, or the difference between the maximum frequency of the WiFi signal and the minimum frequency of the mobile data network signal is not more than 100 MHz.
In an optional implementation manner, the frequency band of the WiFi signal output by the first WiFi signal sending end is WiFi 2.4G, the frequency band of the mobile data network signal output by the first mobile data network signal sending end is N40 frequency band, the frequency band of the WiFi signal output by the second WiFi signal sending end is WiFi 5G, and the frequency band of the mobile data network signal output by the second mobile data network signal sending end is N79 frequency band.
Optionally, the scheme of the embodiment of the application can also be applied to WIFI signal enhancement when 4G/3G/2G and WIFI frequencies meet certain conditions, so that WIFI use experience is improved.
In some embodiments of the present application, the second WiFi signal receiving terminal RX3 of the radio frequency transceiver 31 is respectively connected to the third antenna 333 and the fourth antenna 334, so that when the transmitting power of the third power amplifier 323 meets a third preset condition, the WiFi signal is received through the third antenna 333 and the fourth antenna 334 at the same time, so as to enhance the receiving capability of the WiFi signal, improve the strength of the received WiFi signal, and significantly improve the problem that the WiFi signal is weak or even the electronic device is disconnected.
Similarly, in some optional embodiments of the present application, the third antenna 333 and the fourth antenna 334 serve as both a transmitting antenna and a receiving antenna, and in order to achieve simultaneous transceiving of WiFi signals, the rf circuit may further include a third multiplexer 353 and a fourth multiplexer 354, specifically, the second WiFi signal transmitting terminal TX3 is connected to an input terminal of the third power amplifier 323, an output terminal of the third power amplifier 323 is connected to the third multiplexer 353, and the third multiplexer 353 is further connected to the second WiFi signal receiving terminal RX3 and the third antenna 333, respectively, so as to achieve simultaneous transceiving of WiFi signals by the third antenna 333; similarly, the second mobile data network signal transmitting terminal TX4 and the second WiFi signal transmitting terminal TX3 are respectively connected to the second switch 342, the second switch 342 is connected to the input terminal of the fourth power amplifier 324, the output terminal of the fourth power amplifier 324 is connected to the fourth multiplexer 354, the fourth multiplexer 354 is further connected to the second WiFi signal receiving terminal RX3, the second mobile data network signal receiving terminal RX4 and the fourth antenna 334, respectively, so that the fourth antenna 334 can receive and transmit WiFi signals and mobile data network signals.
Of course, in other alternative embodiments of the present application, if the third antenna 333 and the fourth antenna 334 are only used as transmitting antennas, and the WiFi signal and the mobile data network signal are received by other antennas, a multiplexer may not be used, or the third antenna 333 and the fourth antenna 334 do not need to transmit and receive signals simultaneously, or a multiplexer may not be used.
In some embodiments of the present application, the first antenna 331 may be replaced by a third antenna 333, and the second antenna 332 may be replaced by a fourth antenna 334, that is, the third antenna 333 may be the same antenna as the first antenna 331, and the fourth antenna 334 may be the same antenna as the second antenna 332, so as to reduce the number of antennas. Of course, in the case where the number of antennas is sufficient, the third antenna 333 and the fourth antenna 334 may be different antennas independent from the first antenna 321 and the second antenna 322.
Therefore, the radio frequency circuit can receive and transmit WiFi signals of WiFi 2.4G frequency bands and WiFi signals of WiFi 5G frequency bands.
In the embodiment of the application, under the condition that the transmission power of the WiFi signal meets a certain condition, the power amplifier and the antenna which are used for transmitting the mobile data network signal originally are also used for receiving and transmitting the WiFi signal, so that the problem that the WiFi signal is weak or even is disconnected can be effectively solved.
Referring to fig. 4, fig. 4 is a schematic flowchart illustrating a signal transceiving method according to an embodiment of the present disclosure. As shown in fig. 4, another embodiment of the present application further provides a signal transceiving method applied to the radio frequency circuit in the foregoing embodiment, where the signal transceiving method includes:
step 41: and outputting a WiFi signal through a first WiFi signal sending end of the radio frequency transceiver, and sending the WiFi signal through a first antenna.
In this step, the electronic device resides in a WiFi 2.4G or WiFi 5G network, and then outputs a WiFi signal through a first WiFi signal sending end of the radio frequency transceiver, and sends the WiFi signal through the first antenna after the WiFi signal is amplified by the first power amplifier.
Step 42: under the condition that the transmitting power of a first power amplifier meets a first preset condition, a first switch is utilized to control a first WiFi signal transmitting end to be communicated with a second power amplifier so as to simultaneously transmit WiFi signals through a first antenna and a second antenna;
step 43: and under the condition that the transmitting power of the first power amplifier does not meet a first preset condition, controlling the first mobile data network signal transmitting end to be communicated with the second power amplifier by using a first switch.
After the first power amplifier starts to work, the transmitting power value of the first power amplifier is detected, if the transmitting power of the first power amplifier meets a first preset condition, i.e., indicating that the electronic device is far from the WiFi router, or that there are more obstacles between the two, even though the transmission power of the WiFi signal has maintained the maximum power, the WiFi signal is still weak, and even a drop may occur, the first switch is used to control the first WiFi signal transmitting terminal to communicate with the second power amplifier, to simultaneously transmit WiFi signals through the second antenna, to enhance the strength of the transmitted WiFi signals, and controlling the first mobile data network signal transmitting end to be communicated with the second power amplifier under the condition that the transmitting power of the first power amplifier does not meet a first preset condition, therefore, power consumption is saved, and the mobile data network signal can be normally transmitted and received through the second antenna when the WiFi network is not used.
In an optional implementation manner, when the frequency band of the WiFi signal is WiFi 2.4G, the frequency band of the mobile data network signal output by the first mobile data network signal sending end is an N40 frequency band; and when the frequency band of the WiFi signal is WiFi 5G, the frequency band of the mobile data network signal output by the first mobile data network signal sending end is an N79 frequency band.
The first preset condition is specifically the same as that described in the above embodiment of the rf circuit, and is not described herein again. Optionally, the scheme of the embodiment of the application can also be applied to WIFI signal enhancement when the 4G/3G/2G and WIFI frequencies meet certain conditions, thereby improving WIFI use experience.
In this embodiment, optionally, the signal transceiving method further includes:
and under the condition that the transmitting power of the first power amplifier meets a first preset condition, simultaneously receiving WiFi signals through the first antenna and the second antenna.
That is to say, when the first antenna and the second antenna are used to simultaneously transmit the WiFi signal, the first antenna and the second antenna may also be used to simultaneously receive the WiFi signal, so as to enhance the receiving capability of the WiFi signal and improve the strength of the received WiFi signal.
In this embodiment of the application, optionally, the signal transceiving method further includes:
and when the transmitting power of the first power amplifier does not meet a first preset condition, only the first antenna receives and transmits a WiFi signal.
That is, when the WiFi signal is still used for communication, but the transmission power of the first power amplifier is already lower than a certain preset threshold, the second power amplifier does not need to be used for cooperative work, so the second antenna does not participate in the transceiving of the WiFi signal any more, and only the first antenna performs the transceiving of the WiFi signal. At this time, the first mobile data network signal sending end can be controlled to be communicated with the second power amplifier, so that power consumption is saved, and mobile data network signals can be sent through the second antenna when a WiFi network is not used.
In this embodiment, optionally, the radio frequency circuit further includes a third power amplifier and a fourth power amplifier, a second WiFi signal transmitting end of the radio frequency transceiver is connected to the first antenna through the third power amplifier, the second WiFi signal transmitting end of the radio frequency transceiver and a second mobile data network signal transmitting end of the radio frequency transceiver are respectively connected to a second switch, and the second switch is further connected to the second antenna through the fourth power amplifier, where the method further includes;
outputting a WiFi signal through a second WiFi signal sending end of the radio frequency transceiver, and sending the WiFi signal through a first antenna;
under the condition that the transmitting power of a third power amplifier meets a third preset condition, the second changeover switch is utilized to control the second WiFi signal transmitting end to be communicated with a fourth power amplifier so as to simultaneously transmit WiFi signals through the first antenna and the second antenna;
under the condition that the transmitting power of a fourth power amplifier does not meet a third preset condition, controlling the second mobile data network signal transmitting end to be communicated with the fourth power amplifier by using the second selector switch;
the frequency band of the WiFi signal output by the first WiFi signal sending end is WiFi 2.4G, the frequency band of the mobile data network signal output by the first mobile data network signal sending end is N40 frequency band, the frequency band of the WiFi signal output by the second WiFi signal sending end is WiFi 5G, and the frequency band of the mobile data network signal output by the second mobile data network signal sending end is N79 frequency band.
In the above steps, specifically, after the third power amplifier starts to operate, the transmission power value of the third power amplifier is detected, and if the transmission power of the third power amplifier meets a third preset condition, i.e., indicating that the electronic device is further away from the WiFi router, or that there are more obstacles between the two, even though the transmission power of the WiFi signal has maintained the maximum power, the WiFi signal is still weak, and even a drop may occur, the second switch is used for controlling the second WiFi signal transmitting terminal to communicate with the fourth power amplifier, so as to simultaneously transmit WiFi signals through the first antenna and the second antenna, enhance the strength of the transmitted WiFi signals, and controlling the second mobile data network signal transmitting end to be communicated with the fourth power amplifier under the condition that the transmitting power of the third power amplifier does not meet a third preset condition, therefore, power consumption is saved, and the mobile data network signal can be normally transmitted and received through the second antenna when the WiFi network is not used.
The third preset condition is specifically the same as that described in the above embodiment of the rf circuit, and is not described herein again.
In some embodiments of the present application, the first antenna may be replaced by a third antenna, and the second antenna may be replaced by a fourth antenna, that is, the third antenna may be the same antenna as the first antenna, and the fourth antenna may be the same antenna as the second antenna, so as to reduce the number of antennas. Of course, in case the number of antennas is sufficient, the third antenna and the fourth antenna may also be different antennas independent from the first antenna and the second antenna.
Therefore, the signal transceiving method can be used for transceiving WiFi signals of WiFi 2.4G frequency bands and can also be used for transceiving WiFi signals of WiFi 5G frequency bands.
In the embodiment of the application, under the condition that the transmission power of the WiFi signal meets a certain condition, the power amplifier and the antenna which are used for transmitting the mobile data network signal originally are also used for receiving and transmitting the WiFi signal, so that the problem that the WiFi signal is weak or even is disconnected can be effectively solved.
