In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.

In the following description, references to the terms "first", "second", and the like, are only to distinguish similar objects and do not denote a particular order, but rather the terms "first", "second", and the like may be used interchangeably with the order specified, where permissible, to enable embodiments of the present application described herein to be practiced otherwise than as specifically illustrated or described herein.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.

It should be understood that, in the various embodiments of the present application, the size of the serial number of each implementation process does not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

The processing logic of the signal transmission method of the embodiments of the present application may be deployed in any reasonable electronic device that includes two rf paths (a first rf path and a second rf path) and two antennas (a first antenna and a second antenna). The electronic device may be a terminal or a server. The terminal comprises but is not limited to a tablet computer, an all-in-one machine, a desktop computer, a mobile phone, a smart sound box, a smart watch and the like. The server includes a general server, a cloud server, and the like.

In the embodiment of the application, the electronic device comprises two radio frequency systems. Each radio frequency system includes a radio frequency path and an antenna. If not specifically stated, the present application is only intended to illustrate the transmission process of a signal by using a radio frequency system, and no specific description is made about the reception process of a signal by using a radio frequency system. It can be understood that, at the same time, the electronic device may simultaneously transmit signals of different frequency bands by using the two radio frequency systems. It is also possible to use one of the radio frequency systems for signal transmission and the other radio frequency system to be put in an idle state.

An implementation process of the signal transmission method in the embodiment of the application is applied to electronic equipment. As shown in fig. 1, the method includes:

s101: the first transmitting signal transmits a first target transmitting signal through a first radio frequency path and a first antenna connected with the first radio frequency path; the first target transmitting signal is a signal formed by power amplification of the first transmitting signal through the first radio frequency channel, and the first target transmitting signal corresponds to first actual power;

in this step, the first transmission signal is a signal to be transmitted of the electronic device. The signal to be transmitted is processed by the first rf path to obtain a signal (first target transmission signal) to be transmitted via the first antenna. Wherein, the processing of the signal to be transmitted through the first radio frequency path at least comprises the power amplification of the signal to be transmitted through the first radio frequency path. The signal (first target transmission signal) formed by the power amplification is transmitted via the first antenna.

If the first radio frequency path and the first antenna are regarded as components in a first one of the two radio frequency systems, and the second radio frequency path and the second antenna are regarded as components in a second one of the two radio frequency systems, the foregoing scheme may enable the electronic device to implement transmission of a signal to be transmitted by using the first radio frequency system.

S102: obtaining working parameters of the first radio frequency channel, wherein the working parameters of the first radio frequency channel are used for representing the working state of the first radio frequency channel;

in this step, the working state includes an abnormal working state and a normal working state. The operating parameter of the first rf path may be any parameter that can indicate whether the first rf path is operating abnormally or normally, such as power, temperature, etc.

It can be understood that if the power of the first rf path is within the normal power and/or the temperature of the first rf path is within the normal temperature value, the operating state of the first rf path is the normal state. And if the power of the first radio frequency channel is out of the normal power and/or the temperature of the first radio frequency channel is out of the normal temperature value, the working state of the first radio frequency channel is an abnormal state.

S103: if the working parameters of the first radio frequency channel meet the switching condition, the first transmitting signal transmits a second target transmitting signal through a second radio frequency channel and a second antenna connected with the second radio frequency channel, the second target transmitting signal is a signal formed by power amplification of the first transmitting signal through the second radio frequency channel, and the second target transmitting signal corresponds to second actual power; wherein the second actual power is closer to a target power than the first actual power.

In this step, the switching condition may be considered as any reasonable condition for determining that the operating state of the first rf path is abnormal. For example, the power of the first rf path is out of the normal power, the temperature of the first rf path is out of the normal temperature value, and the like. If the working parameter of the first radio frequency channel meets the switching condition, which indicates that the working state of the first radio frequency channel is abnormal, and normal transmission of the signal to be transmitted cannot be realized, the radio frequency system used by the electronic device to transmit the signal to be transmitted needs to be switched from the first radio frequency system to a second radio frequency system, so that the second radio frequency system is used to realize normal transmission of the signal to be transmitted.

In the scheme of implementing normal transmission of the signal to be transmitted by using the second rf system, the signal to be transmitted is processed by the second rf path to obtain a signal (a second target transmission signal) to be transmitted via the second antenna. Wherein, the processing of the signal to be transmitted through the second radio frequency path at least comprises the power amplification of the signal to be transmitted through the second radio frequency path. The signal (second target transmission signal) formed by the power amplification is transmitted via the second antenna.

It should be noted that, in the embodiment of the present application, when the first radio frequency system is used to implement transmission of a signal to be transmitted, an actual power (first actual power) of a first target transmission signal transmitted via the first antenna is also required. And, in the case of implementing transmission of the signal to be transmitted using the second radio frequency system, the actual power (second actual power) of the second target transmission signal transmitted via the second antenna is also required. The target power is an ideal transmission power for the signal to be transmitted when the electronic device expects to transmit the signal. The second actual power is closer to the target power, i.e. closer to the ideal transmit power, than the first actual power.

That is, in a scheme in which the electronic device switches from the first radio frequency system to the second radio frequency system to implement normal transmission of the signal to be transmitted by using the second radio frequency system, compared with the case in which the first radio frequency system transmits the signal to be transmitted, the second radio frequency system is better capable of transmitting the signal to be transmitted at an ideal transmission power expected by the electronic device. The ideal transmitting power is used for transmitting, so that the transmitting loss of the signal to be transmitted can be avoided to the greatest extent, for example, the signal can generate certain attenuation due to the processing of the radio frequency system, the second radio frequency system is used for transmitting the signal to be transmitted, the attenuation of the signal to be transmitted can be reduced to the greatest extent, the signal to be transmitted is transmitted in a more ideal gain degree, namely, the signal to be transmitted is transmitted in a full-gain mode as far as possible, and the transmission efficiency is improved.

In implementation, power detection circuits may be provided for the first rf path and the second rf path, and the first actual power and the second actual power are obtained through the power detection circuits. The method is easy to realize in engineering and high in feasibility.

In S101 to S103, a first radio frequency system is used to transmit a signal to be transmitted, and when a working parameter of a first radio frequency channel satisfies a switching condition, a radio frequency system for performing radio frequency transmission on the signal to be transmitted is switched from the first to the second, and a second radio frequency system is used to transmit the signal to be transmitted. Compared with the scheme that the normal transmission of the signal to be transmitted cannot be realized in the related technology, the embodiment of the application utilizes two radio frequency systems and utilizes the switching of the radio frequency systems to ensure the normal transmission of the signal to be transmitted. And the switched second radio frequency system can transmit the signal to be transmitted with the ideal transmission power expected by the electronic equipment, so that the attenuation of the signal to be transmitted is reduced to the greatest extent, and the transmission efficiency is improved. Technical support is provided for enabling the signal to be transmitted with the expected ideal transmission power.

In an alternative, the first actual power may be used as an operating parameter of the first radio frequency path, a difference between the first actual power and the target power is calculated, and if the difference satisfies a set difference threshold, it is determined that the operating parameter of the first radio frequency path satisfies the handover condition. And when the absolute value of the difference between the first actual power and the target power is greater than or equal to the difference threshold, the difference is considered to meet the set difference threshold.

In an alternative, the temperature of the first rf path may be used as the operating parameter of the first rf path, and it is determined whether the temperature parameter of the first rf path reaches a set temperature threshold, and if so, it is determined that the operating state of the first rf path satisfies the switching condition.

Based on this, referring to fig. 2, after S102, the method further includes:

s104: determining that the working parameter of the first radio frequency channel meets a switching condition under the condition that at least one of the following conditions is met; a difference between the first actual power and the target power satisfies a difference threshold; the temperature parameter of the first radio frequency path reaches a temperature threshold.

S103 becomes S103': the first transmitting signal transmits a second target transmitting signal through a second radio frequency path and a second antenna connected with the second radio frequency path, the second target transmitting signal is a signal formed by power amplification of the first transmitting signal through the second radio frequency path, and the second target transmitting signal corresponds to second actual power; wherein the second actual power is closer to a target power than the first actual power.

In the scheme, based on power and/or temperature, whether the working parameters of the first radio frequency channel meet the switching conditions or not is judged, whether switching is accurate or not can be determined, and further, the normal transmission of the signals to be transmitted is guaranteed.

As an alternative, when the first transmission signal transmits a second target transmission signal through the second radio frequency path and a second antenna connected to the second radio frequency path, obtaining a working parameter of the second radio frequency path, where the working parameter of the second radio frequency path represents a working state of the second radio frequency path; and if the working state of the second radio frequency path meets the switching condition, the first transmitting signal transmits a first target transmitting signal through the first radio frequency path and a first antenna connected with the first radio frequency path.

In a popular way, the second radio frequency system is used for transmitting the signal to be transmitted, when the working parameters of the second radio frequency channel meet the switching conditions, the radio frequency system for performing radio frequency transmission on the signal to be transmitted is switched back to the first radio frequency system from the second radio frequency system, and the first radio frequency system is used for transmitting the signal to be transmitted. And ensuring the normal transmission of the signal to be transmitted based on the back-and-forth switching between the two radio frequency systems.

The understanding that the working parameters, the working state, and the working state of the second rf path satisfy the switching condition can be referred to the related description of the first rf path, and the repeated details are not repeated.

It will be appreciated that since the electronic device may operate in different networking modes, such as independent networking (SA) or non-independent Networking (NSA), the first and second radio paths may be considered as two radio paths in the SA network or as two radio paths in the NSA network.

If the first radio frequency path and the second radio frequency path are regarded as two radio frequency paths under the SA network, and only one of the two radio frequency paths is in the working state at the same time, the second radio frequency path needs to be in the idle state when the first transmission signal transmits the first target transmission signal through the first radio frequency path and the first antenna connected to the first radio frequency path. And if the working parameter of the first radio frequency channel meets the switching condition, the first transmitting signal can obtain a second target transmitting signal through a second radio frequency channel in an idle state. Therefore, the embodiment of the application can ensure the normal transmission of the signal to be transmitted under the SA network.

It should be noted that, in this application, the operating state and the idle state are relative, and the operating state refers to a state where the first radio frequency path is operating, such as a state where power amplification is performed on a signal to be transmitted.

If the first rf path and the second rf path are regarded as two rf paths in the NSA network, since both rf paths may be in a working state at the same time, when the first transmission signal transmits the first target transmission signal through the first rf path and the first antenna, the second rf path and the second antenna are not in an idle state and are in a working state, for example, a second transmission signal different from the first transmission signal is transmitted. Further, the second transmitting signal transmits a third target transmitting signal through a second radio frequency path and a second antenna connected with the second radio frequency path; the third target transmission signal is a signal formed by power amplification of the second transmission signal through the second radio frequency path.

In the foregoing scheme, that the first transmission signal and the second transmission signal are different may mean that the first transmission signal and the second transmission signal are signals with different frequency bands. If the first transmission signal is a first frequency band, the second transmission signal is a second frequency band; the second frequency band is higher than the first frequency band. That is, when the first rf path and the first antenna are used to transmit low band signals, the second rf path and the first rf path may transmit high band signals. The normal transmission of high-frequency and low-frequency band signals is realized, and mutual interference cannot be caused.

And if the working parameters meet the switching conditions, stopping the transmission of the second transmission signal by the second radio frequency channel and the second antenna, and switching the second radio frequency channel and the second antenna to an idle state. Thus, the first transmission signal transmits the second target transmission signal through the second radio frequency path in the idle state and the second antenna connected with the second radio frequency path. The normal transmission of the signal to be transmitted is ensured.

The technical solution of the present application is further explained below with reference to fig. 3 to 4.

Taking the electronic device as a 5G mobile phone as an example, the 5G mobile phone includes two radio frequency systems, each radio frequency system includes a radio frequency path and an antenna. Briefly, a 5G handset includes two radio frequency paths and two antennas (antenna 1 and antenna 2).

Both radio frequency paths include: a radio frequency transceiver and a Power Amplifier (PA) coupled to the radio frequency transceiver. One end of the PA is connected with the radio frequency transceiver, and the other end of the PA is connected with the antenna. In addition, both rf paths may also include power detection circuitry connected to both the PA and the antenna at the same end.

Combining the rf transceivers in the two rf paths into one rf transceiver results in the circuit shown in fig. 3.

Specifically, in fig. 3, the first rf path includes a PA1, an antenna 1, a power detection circuit 1, and a temperature detection circuit 1 connected to the PA 1. The second radio frequency path includes a PA2, an antenna 2, a power detection circuit 2, and a temperature detection circuit 2 connected to the PA 2. The radio frequency transceiver is used as a common part in two radio frequency paths and is used for outputting a signal to be transmitted to the power amplifier. The

temperature detection circuits

1 and 2 may be thermistors for measuring the temperature of the power amplifier.

In an alternative, the temperature detection circuit 1 and the temperature detection circuit 2 may be combined into one temperature detection circuit. The power detection circuit 1 and the power detection circuit 2 may be combined into one power detection circuit.

Fig. 4 is an example of a 5G mobile phone transmitting a signal to be transmitted in an SA network, where PA1 is configured to perform power amplification on the signal to be transmitted (a first transmission signal) to obtain a first target transmission signal. The antenna 1 is used for transmitting a first target transmission signal.

The specific process is shown in fig. 4: firstly, whether the 5G mobile phone is in the SA network is judged, and if so, whether the 5G mobile phone is in a transmitting state is judged. If not, the process ends.

It should be noted that, in the SA network, only one PA can operate at the same time, and if the transmission of the signal to be transmitted is implemented by using the PA1 and the antenna 1 in the application scenario, the PA2 and the antenna 2 need to be in an idle state when the transmission of the signal to be transmitted is implemented by using the PA1 and the antenna 1.

If in the transmitting state, the actual power of the first target transmission signal obtained through the PA1 power amplification is detected by the detection circuit 1 as the first actual power. It is determined whether the absolute value of the difference between the first actual power and the target power is greater than or equal to a set difference threshold, such as 2dbm.

If the actual power of the first target transmitting signal obtained through PA1 power amplification is larger than or equal to the ideal transmitting power of the 5G mobile phone, the PA1 is determined to be in an abnormal state, and the switching condition is met. The reason for this may be that PA1 is abnormal and normal amplification of the signal cannot be achieved. The problem that the signals to be transmitted cannot be normally transmitted due to the fact that the PA1 is abnormal is solved. And switching the signal to be transmitted to a second radio frequency channel, specifically switching to a PA2 for power amplification, and transmitting a second target transmission signal obtained by amplifying the PA2 through an antenna 2.

And if the absolute value of the difference between the first actual power and the target power is judged to be less than 2dbm, continuing to use the PA1 to amplify the power of the signal to be transmitted and transmitting the first target transmission signal obtained by amplifying the power through the antenna 1. The temperature detection circuit 1 is used for measuring the temperature of the PA1, whether the temperature of the PA1 reaches a set temperature threshold value is judged, if yes, the temperature of the PA1 is over high, and abnormity occurs, the PA1 is determined to be in an abnormal state, and the switching condition is met. And switching the signal to be transmitted to the PA2 for power amplification, and transmitting a second target transmission signal obtained by amplifying the PA2 through the antenna 2. If the temperature of PA1 does not reach the set temperature threshold value, the temperature of PA1 is continuously measured by the temperature detection circuit 1.

Therefore, the normal transmission of the signal to be transmitted can be realized based on the switching from the first radio frequency system to the second radio frequency system under the condition that the PA1 cannot normally amplify and/or has overhigh temperature, namely, is abnormal. In addition, the PA2 is in an idle state, normal power amplification of a signal to be transmitted can be achieved, the PA2 and the antenna 2 can be used for transmitting the signal to be transmitted with ideal transmission power expected by a 5G mobile phone, attenuation of the signal to be transmitted can be reduced to the greatest extent, and transmission efficiency is improved.

In the process of realizing the transmission of the signal to be transmitted by using the PA2 and the antenna 2, the PA1 is gradually recovered from the abnormal state to the normal state because the PA is no longer in the working state. In order to avoid that the PA2 cannot normally transmit signals due to abnormality, in the process of transmitting signals to be transmitted by using the PA2 and the antenna 2, the actual power of a second target transmission signal obtained by amplifying the power of the PA2 is detected by the detection circuit 2 as second actual power. It is determined whether the absolute value of the difference between the second actual power and the target power is greater than or equal to a set difference threshold, such as 2dbm. If the actual power of the second target transmitting signal obtained through PA2 power amplification is larger than or equal to the ideal transmitting power of the 5G mobile phone, the PA2 is determined to be in an abnormal state, and the switching condition is met. And switching the signal to be transmitted to the PA1 for power amplification, and transmitting a first target transmission signal obtained by amplifying the PA1 through the antenna 1.

And if the absolute value of the difference between the second actual power and the target power is judged to be less than 2dbm, measuring the temperature of the PA2 by using the temperature detection circuit 2, judging whether the temperature of the PA2 reaches a set temperature threshold value, and if so, indicating that the temperature of the PA2 is overhigh and abnormal and meeting the switching condition. And switching the signal to be transmitted to the PA1 for power amplification, and transmitting a first target transmission signal obtained by amplifying the PA1 through the antenna 1. Therefore, the switching from the second radio frequency system to the first radio frequency system is realized, and the normal transmission of the signal to be transmitted is ensured based on the back-and-forth switching between the two radio frequency systems. Technical support is provided for enabling the signal to be transmitted with the expected ideal transmission power.

In the following, the 5G mobile phone transmits a signal to be transmitted in the NSA network. Under the NSA network, PA1 and antenna 1 are allocated for use with a first transmitted signal, such as a 4G signal. PA2 and antenna 2 are allocated for use with a second transmit signal, such as a 5G signal. The frequency band of 5G signals is typically higher than the frequency band of 4G signals.

The specific process is as follows:

firstly, whether the 5G mobile phone is in the NSA network is judged, and if yes, whether the 5G mobile phone is in a transmitting state is judged. If not, the process ends.

It should be noted that in the NSA network, two PAs are simultaneously operating at the same time. If the 4G signal is transmitted by using the PA1 and the antenna 1 in the application scenario, when the 4G signal is transmitted by using the PA1 and the antenna 1, the 5G signal is transmitted by using the PA2 and the antenna 2. The PA2 is configured to perform power amplification on the 5G signal to form a third target transmission signal, and the antenna 2 is configured to transmit the third target transmission signal.

The actual power (first actual power) of the first target transmission signal obtained through the PA1 power amplification is detected by the detection circuit 1.

If the absolute value of the difference between the first actual power and the target power is judged to be greater than or equal to 2dbm, the difference between the actual power of the first target transmitting signal obtained through PA1 power amplification and the ideal transmitting power of the 5G mobile phone is more, the PA1 is abnormal, and the working state of the PA1 is determined to meet the switching condition. At this time, although PA2 is in operation, no idle PA is available for switching. However, in the 5G handset, when the 4G signal and the 5G signal are transmitted simultaneously, since the 4G signal needs to be transmitted preferentially as the primary carrier and the 5G signal may not be transmitted preferentially as the secondary carrier, the transmission of the 5G signal by the PA2 and the antenna 2 may be stopped, so that the PA2 and the antenna 2 are switched from the operating state to the idle state.

And if the absolute value of the difference between the first actual power and the target power is judged to be less than 2dbm, the temperature of the PA1 is measured by using the temperature detection circuit 1, whether the temperature of the PA1 reaches a set temperature threshold value is judged, and if the temperature of the PA1 is over-high and abnormal, the PA1 is determined to be in an abnormal state and meets the switching condition. PA2 and antenna 2 are switched from the active state to the idle state.

And under the conditions that the working state of the PA1 is an abnormal state and the switching condition is met, switching the 4G signal to an idle second radio frequency path, specifically to the PA2 for power amplification, and transmitting a second target transmission signal obtained by amplifying the PA2 through the antenna 2.

If the temperature of PA1 does not reach the set temperature threshold value, the temperature of PA1 is continuously measured by the temperature detection circuit 1.

Therefore, when no abnormity occurs in PA1, 4G signals are transmitted by using PA1 and antenna 1, and 5G signals are transmitted by using PA2 and antenna 2. And in the case that the PA1 cannot amplify normally and/or the temperature is too high, namely, an abnormality occurs, stopping the transmission of the 5G signal, and putting the PA2 and the antenna 2 in an idle state. Based on the switching of the PA1 and the antenna 1 to the PA2 and the antenna 2, the normal transmission of the signal to be transmitted is realized.

When the PA1 is gradually recovered to normal from the abnormity and the PA2 and the antenna 2 can normally realize the transmission of the 4G signal, the PA1 and the antenna 1 are enabled again, and the 5G signal is transmitted by using the enabled PA1 and the antenna 1, so that the normal transmission of the 5G signal is realized.

It can be understood that if PA1 and antenna 1 that are re-enabled transmit 5G signals, and PA2 and antenna 2 transmit 4G signals, if PA2 is abnormal, then PA1 and antenna 1 need to stop transmitting 5G signals, that is, PA1 and antenna 1 need to be switched from the working state to the idle state. The 4G signal is switched back from PA2 to PA1 for power amplification and transmitted via antenna 1. Based on this switching, transmission of the 4G signal is preferentially guaranteed.

In summary, with the technical solution of the embodiment of the present application, normal transmission of a signal to be transmitted in an SA network can be achieved based on switching between different PAs and different antennas. In the NSA network, when PA1 is abnormal, the 4G signal originally amplified by PA1 is amplified by PA2 in an idle state based on the switching from the operating state to the idle state of PA2 and antenna 2, and is transmitted by antenna 2, so that the transmission of the 4G signal is preferentially ensured. Technical support is provided for enabling the signal to be transmitted with the expected ideal transmission power.
