The method provided by the embodiment of the application is applied to a scene of transmitting signals, the terminal is provided with two uplink radio frequency channels, and when the terminal transmits radio frequency signals through the two uplink radio frequency channels, the method provided by the embodiment of the application can adjust the phase of the radio frequency signal of one uplink radio frequency channel based on the determined target phase difference, so that no phase difference exists between the radio frequency signal after the phase is adjusted and the radio frequency signal transmitted by the other uplink radio frequency channel, and the effect of doubling the transmitting power of the terminal is achieved.

The method provided by the embodiment of the Application is applied to a terminal, and the terminal comprises a first uplink radio frequency channel and a first downlink radio frequency channel which share a first antenna, a second uplink radio frequency channel and a second downlink radio frequency channel which share a second antenna, an Application Processor (AP) & BB (Baseband ), and a Baseband and radio frequency chip. For example, as shown in fig. 2, the AP & BB is connected to a radio frequency chip, and the first uplink radio frequency path, the first downlink radio frequency path, the second uplink radio frequency path, and the second downlink radio frequency path are respectively connected to the radio frequency chip, and the first uplink radio frequency path and the first downlink radio frequency path are connected to the first antenna, and the second uplink radio frequency path and the second downlink radio frequency path are connected to the second antenna.

The first downlink radio frequency channel and the second downlink radio frequency channel receive radio frequency signals through the first antenna and the second antenna respectively, then forward the radio frequency signals to the radio frequency chip, and the AP & BB analyzes the two received radio frequency signals.

In addition, the AP & BB sends a signal transmission instruction to the radio frequency chip, and the radio frequency chip generates a radio frequency signal according to the transmission instruction, and the first uplink radio frequency channel and the second uplink radio frequency channel transmit the radio frequency signal through the first antenna and the second antenna, respectively.

In addition, as shown in fig. 3, the first uplink radio frequency path and the second uplink radio frequency path each include a power amplifier, a filter or a duplexer, a switch, and a matching circuit. The first downlink radio frequency path and the second downlink radio frequency path respectively comprise a low noise amplifier, a filter or a duplexer, a switch and a matching circuit.

In addition, since the phases of the radio frequency signals of the first uplink radio frequency path, the second uplink radio frequency path, the first downlink radio frequency path, or the second downlink radio frequency path need to be adjusted in the embodiment of the present application, a phase shifter is respectively disposed in the radio frequency paths where the phases of the radio frequency signals need to be adjusted, and the phase shifters are used to complete the adjustment of the phases of the radio frequency signals.

Wherein, the phase shifter can be at any position in the first uplink radio frequency path. The phase shifter may be at any location in the second upstream radio frequency path. The phase shifter may be at any location in the first downlink radio frequency path. The phase shifter may be at any location in the second downstream radio frequency path.

For example, as shown in fig. 4, the phase shifter is disposed in front of the power amplifier, and since the radio frequency signal does not pass through the power amplifier to amplify power first, the power requirement of the phase shifter does not need to be too high, the phase of the radio frequency signal can be adjusted by using the phase shifter with low power, and the control effect on the radio frequency signal can be improved.

For another example, as shown in fig. 5, the phase shifter is disposed after the switch, so that, even if the switch is switched during operation, the phase of the radio frequency signal does not jump due to the switching of the switch, thereby ensuring that no phase deviation occurs during the phase adjustment of the radio frequency signal, and improving the accuracy of determining the phase difference between the first antenna and the second antenna.

It should be noted that, in the embodiment of the present application, only the phase shifter is disposed in the first uplink radio frequency path for example, in another embodiment, the effect of disposing the phase shifter in the other radio frequency paths is similar to the effect of disposing the phase shifter in the first uplink radio frequency path, and details are not repeated here.

Fig. 6 shows a flowchart of a signal adjustment method provided in an exemplary embodiment of the present application, and referring to fig. 6, the method is applied to a terminal, where the terminal includes a first uplink radio frequency path and a first downlink radio frequency path that share a first antenna, and a second uplink radio frequency path and a second downlink radio frequency path that share a second antenna, and the method includes:

601. and acquiring a plurality of total powers of the radio frequency signals of the first downlink radio frequency channel and the second downlink radio frequency channel by adjusting the phase of the radio frequency signal of the first downlink radio frequency channel and/or the second downlink radio frequency channel.

In the embodiment of the application, the terminal can transmit radio frequency signals through the first uplink radio frequency channel and the second uplink radio frequency channel, the two radio frequency signals are overlapped to improve the transmission power of the terminal, but since the radio frequency signals are transmitted by the terminal, the radio frequency power after the two radio frequency signals are overlapped cannot be determined, and the terminal can obtain the total power of the two received radio frequency signals after receiving the radio frequency signals through the first downlink radio frequency channel and the second downlink radio frequency channel, so that the phase of the radio frequency signals of the first downlink radio frequency channel and/or the second downlink radio frequency channel is adjusted, and the phase difference of the radio frequency signals transmitted by the two uplink radio frequency channels and the phase difference of the radio frequency signals received by the two downlink radio frequency channels are determined according to the total power of the radio frequency signals after the phase adjustment.

Before determining the phase difference between the two uplink radio frequency paths or the two downlink radio frequency paths, adjusting the phases of the radio frequency signals of the first downlink radio frequency path and/or the second downlink radio frequency path to obtain radio frequency signals after the actions are adjusted, and acquiring the total power of the radio frequency signals of the first downlink radio frequency path after the phases are adjusted and the radio frequency signals of the second downlink radio frequency path after the phases are adjusted.

In this embodiment of the present application, by adjusting the phase of the radio frequency signal of the first downlink radio frequency channel and/or the second downlink radio frequency channel for multiple times, multiple total powers of the radio frequency signal of the first downlink radio frequency channel and the second downlink radio frequency channel may be obtained.

602. And determining the target phase difference of the radio frequency signals transmitted by the first uplink radio frequency channel and the second uplink radio frequency channel according to the plurality of total powers.

In this embodiment of the application, after the phases of the radio frequency signals of the first downlink radio frequency channel and/or the second downlink radio frequency channel are adjusted, since the total power can represent a difference in phase between the two radio frequency signals, a target phase difference between the radio frequency signals transmitted by the first uplink radio frequency channel and the second uplink radio frequency channel is determined according to a plurality of obtained total powers, and the determined target phase difference can eliminate a phase difference between the radio frequency signals of the two radio frequency channels.

603. And adjusting the phase of the first uplink radio frequency channel and/or the second uplink radio frequency channel by adopting the target phase difference and transmitting.

In this embodiment of the application, because the first uplink rf path and the first downlink rf path share the first antenna, the second uplink rf path and the second downlink rf path share the second antenna, and a phase difference between two rf signals received by the terminal through the first downlink rf path and the second downlink rf path is caused by a path difference generated by the first antenna and the second antenna, a phase difference between two rf signals transmitted by the first uplink rf path and the second uplink rf path is the same as a phase difference between two rf signals received by the first downlink rf path and the second uplink rf path, so that a phase difference does not exist between the two rf signals transmitted by the two uplink rf paths.

The embodiment of the application provides a signal adjusting method, which includes adjusting phases of radio-frequency signals received by a first downlink radio-frequency channel and/or a second downlink radio-frequency channel to obtain total power of the adjusted radio-frequency signals, and adjusting the phases of the radio-frequency signals of the first uplink radio-frequency channel and/or the second uplink radio-frequency channel by adopting a target phase difference determined according to a plurality of total powers.

Fig. 7 is a flowchart illustrating a signal adjustment method according to an exemplary embodiment of the present application, and referring to fig. 7, the method is applied to a terminal, where the terminal includes a first uplink rf path and a first downlink rf path that share a first antenna, and a second uplink rf path and a second downlink rf path that share a second antenna, and the method includes:

701. and acquiring a total power of the radio frequency signals of the first downlink radio frequency channel and the second downlink radio frequency channel by adjusting the phase of the radio frequency signal of the first downlink radio frequency channel.

In this embodiment, the terminal may receive radio frequency signals through the first downlink radio frequency path and the second downlink radio frequency path at the same time, and the terminal may adjust phases of a plurality of radio frequency signals received through the first downlink radio frequency path to obtain radio frequency signals with a plurality of adjusted phases, and then obtain a total power of the radio frequency signal with each adjusted phase and a radio frequency signal with the corresponding second downlink radio frequency path.

The terminal equipment receives radio frequency signals through the first downlink radio frequency channel and receives radio frequency signals through the second downlink radio frequency channel at the same time, the radio frequency signals received through the two downlink radio frequency channels at the same time have a corresponding relation, and when the total power is obtained, the total power of the radio frequency signals received by the first radio frequency channel after the phase adjustment and the radio frequency signals received by the second downlink radio frequency channel at the same time is also obtained.

In some embodiments, the first downlink radio frequency path includes a first phase shifter, and the phase of the radio frequency signal of the first downlink radio frequency path is adjusted by adjusting the phase of the first phase shifter when adjusting the phase of the radio frequency signal of the first downlink radio frequency path.

For example, the phase of the first phase shifter is set as the phase adopted by the current phase adjustment, and then the phase of the first phase shifter is adopted to adjust the phase of the radio frequency signal of the first downlink radio frequency channel, so as to obtain the radio frequency signal after the phase adjustment, and obtain the total power of the radio frequency signal after the phase adjustment and the radio frequency signal of the second downlink radio frequency channel.

The terminal sets the phase of the first phase shifter as the phase adopted this time, and the first phase shifter can adjust the phase of the radio frequency signal received this time through the first downlink radio frequency channel to obtain an adjusted radio frequency signal, and the adjusted radio frequency signal corresponds to the radio frequency signal simultaneously received this time through the second downlink radio frequency channel.

The phase of the first phase shifter is set by a terminal, or set by an operator, or set by other methods.

For example, when the terminal receives a radio frequency signal through the first downlink radio frequency path for the first time and receives a radio frequency signal through the second downlink radio frequency path, the phase of the first phase shifter is set to 0 degree, or the phase of the first phase shifter is set to 30 degrees.

In other embodiments, a sum of the radio frequency signals of the first downlink radio frequency channel and the second downlink radio frequency channel is obtained, and the total power of the radio frequency signals of the first downlink radio frequency channel and the second downlink radio frequency channel is determined according to the obtained sum.

After the terminal adjusts the radio frequency signal of the first downlink radio frequency channel, the sum of the radio frequency signal after the phase adjustment and the radio frequency signal of the second downlink radio frequency channel is obtained, the obtained sum represents the energy of the radio frequency signal after the phase adjustment and the radio frequency signal of the second downlink radio frequency channel, and then the total power of the radio frequency signal of the first downlink radio frequency channel and the radio frequency signal of the second downlink radio frequency channel is determined and adjusted according to the obtained sum.

The larger the total power of the radio frequency signal after the phase adjustment and the radio frequency signal of the second downlink radio frequency channel is, the smaller the phase difference between the radio frequency signal after the phase adjustment and the radio frequency signal of the second downlink radio frequency channel is, and the higher the accuracy of adjusting the phase of the radio frequency signal of the first downlink radio frequency channel is.

702. And increasing the phase adopted by the adjustment according to the target step length to obtain the increased phase.

In this embodiment of the present application, since the terminal needs to determine the phase difference between the radio frequency signals that can double the transmission power of the terminal, the radio frequency signal received by the first downlink radio frequency channel needs to be adjusted multiple times according to different phases to obtain the radio frequency signal with the phase adjusted multiple times, after obtaining a total power, the phase used in this adjustment is increased according to a target step length to obtain an increased phase, and the increased phase is used for adjusting the phase of the radio frequency signal received by the first downlink radio frequency channel next time.

The target step length is set by a terminal, or set by an operator, or set by other methods. For example, the target step size is 10 degrees, 20 degrees, 30 degrees, or other values.

In some embodiments, the ratio of the total phase to the preset number is determined as the target step size.

The preset number is set by a terminal, or set by an operator, or set by other modes. For example, the predetermined number may be 10, 20, 40, or other values.

Since the radio frequency signal is periodically changed, and one period is 360 degrees, when the target step length is set, the total phase is set to 360 degrees, and the ratio of 360 degrees to the preset number is determined as the target step length.

703. And adjusting the phase of the radio frequency signal of the first downlink radio frequency channel by adopting the increased phase for the next time, and acquiring the total power of the radio frequency signals of the first downlink radio frequency channel and the second downlink radio frequency channel.

After determining the phase difference of the increased target step size through step 702, the phase of the radio frequency signal of the first downlink radio frequency channel is adjusted by using the increased phase next time, so as to obtain an adjusted radio frequency signal, and the phase difference between the adjusted radio frequency signal and the radio frequency signal before adjustment is the increased phase.

In some embodiments, the phase of the first phase shifter included in the first downlink rf path of the terminal is set to the increased phase, and the phase of the rf signal of the first downlink rf path is adjusted by using the first phase shifter, so as to obtain an adjusted rf signal.

In the embodiment of the present application, the radio frequency signal of the first downlink radio frequency channel is adjusted by changing the phase used each time according to the target step length, and if the value of the target step length is smaller, the interval of the phases used for adjusting the radio frequency signal is smaller, the accuracy of adjusting the radio frequency signal is higher, and if the value of the target step length is larger, the interval of the phases used for adjusting the radio frequency signal is larger, and the accuracy of adjusting the radio frequency signal is lower.

In this embodiment, the terminal performs step 703 for multiple times to complete a process of adjusting the phase of the radio frequency signal received through the first downlink radio frequency path for multiple times, and when the phase difference adopted by the terminal is 360 degrees, it is determined that the terminal adjusts the phase of the radio frequency signal for the last time.

In a possible implementation manner, a phase control module is disposed in the terminal, and the phase control module is connected to the first phase shifter, and the terminal adjusts the phase of the first phase shifter by using the phase control module. The phase control module may be a module included in a processor of the terminal or a module newly added in the terminal.

It should be noted that, in the embodiment of the present application, the total power of the adjusted radio frequency signal and the radio frequency signal of the second downlink radio frequency channel obtained twice in steps 701 to 703 is only taken as an example for explanation. The above steps are described in detail below by way of example.

In this embodiment, if the total phase adopted by the terminal is 360 degrees and the preset number is 36, the determined target step is 10 degrees, and the process of adjusting the phase of the radio frequency signal of the first downlink radio frequency channel by the subsequent terminal by adopting the phase is as follows:

the terminal adjusts the phase of the radio frequency signal of the first downlink radio frequency channel by adopting the phase 0 for the first time, and obtains the total power of the adjusted radio frequency signal and the radio frequency signal of the second downlink radio frequency channel.

And the terminal adjusts the phase of the radio-frequency signal of the first downlink radio-frequency channel by adopting the phase of 10 degrees for the second time, and obtains the total power of the adjusted radio-frequency signal and the radio-frequency signal of the second downlink radio-frequency channel.

And the terminal adjusts the phase of the radio frequency signal of the first downlink radio frequency channel by adopting the phase of 20 degrees for the third time, and obtains the total power of the adjusted radio frequency signal and the radio frequency signal of the second downlink radio frequency channel.

By parity of reasoning, the terminal adjusts the phase of the radio frequency signal of the first downlink radio frequency channel by adopting the phase 360 degrees for the last time, and obtains the total power of the adjusted radio frequency signal and the radio frequency signal of the second downlink radio frequency channel.

In some embodiments, the terminal receives on the first downlink RF path with a different phaseThe phase adjustment of the rf signal is actually performed by adjusting the phase of a first phase shifter included in the first downlink rf path. For example, if the total phase is 360 degrees and the preset number is 36, the determined target step size is 10 degrees. Wherein the phase of the phase shifter is w _n = (n + 1) Δ ω; wherein, ω is _n For the nth phase, Δ ω is the target step size, and n is not greater than the target number of positive integers.

The terminal sets the phase of the first phase shifter to 0 for the first time, and the first phase shifter is adopted to complete the adjustment of the radio frequency signal of the first downlink radio frequency channel and obtain the total power of the adjusted radio frequency signal and the radio frequency signal of the second downlink radio frequency channel.

And the terminal sets the phase of the first phase shifter to 10 for the second time, and the first phase shifter is adopted to complete the adjustment of the radio frequency signal of the first downlink radio frequency channel and obtain the total power of the adjusted radio frequency signal and the radio frequency signal of the second downlink radio frequency channel.

By analogy, the terminal sets the phase of the first phase shifter to 360 for the last time, and the first phase shifter is adopted to complete the adjustment of the radio frequency signal of the first downlink radio frequency channel and obtain the total power of the adjusted radio frequency signal and the radio frequency signal of the second downlink radio frequency channel.

It should be noted that, in the embodiments of the present application, only the phase of the radio frequency signal of the first downlink radio frequency path is adjusted by sequentially using different phase differences from front to back. In another embodiment, the first downlink rf path includes a plurality of first sub-paths, and after receiving the rf signal through the plurality of first sub-paths, for each first sub-path in the plurality of first sub-paths, the phase of the rf signal of the first sub-path is adjusted by using the phase of each first sub-path, so as to obtain the total power of the rf signal after the phase adjustment and the rf signal of the second downlink rf path.

Wherein the plurality of first sub-paths correspond to different phases. For example, the difference in phase difference between two adjacent first sub-paths is a target step size.

In this embodiment, when the terminal receives a radio frequency signal, the terminal receives a radio frequency signal through each first sub-path, and each first sub-path adjusts the received radio frequency signal by using the phase of each first sub-path, so as to obtain the radio frequency signal adjusted by each first sub-path and adjust the phase difference corresponding to each radio frequency signal, which also means that there are several sub-paths, and several adjusted radio frequency signals and corresponding phase differences can be obtained at one time.

For example, the first downlink rf path of the terminal includes 4 first sub-paths, and the target step is 90 degrees, the phase set in each first sub-path is 0, 90 degrees, 180 degrees, and 270 degrees, and after the rf signal is received through each first sub-path, the phase of the rf signal can be adjusted according to the respective phase.

In some embodiments, each of the first sub-paths in the plurality of first sub-paths includes a first phase shifter, each time a radio frequency signal is received through the first downlink radio frequency path, a phase of the first phase shifter in each of the first sub-paths is set to be a phase adopted by each of the first sub-paths, and the first phase shifter of each of the first sub-paths is used to adjust the phase of the radio frequency signal of each of the first sub-paths, so as to obtain a total power of the radio frequency signal after the phase adjustment and the radio frequency signal of the second downlink radio frequency path.

In the embodiment of the present application, if the phases of the radio frequency signals of the first downlink radio frequency channel and/or the second downlink radio frequency channel are directly adjusted for multiple times, the number of times of adjustment is excessive, and the efficiency is low, so the phases of the radio frequency signals of the first downlink radio frequency channel and/or the second downlink radio frequency channel are adjusted according to the predicted phases, and then two reference phases are determined according to the obtained total powers of the radio frequency signals of the first downlink radio frequency channel and the second downlink radio frequency channel, where a target phase difference of the radio frequency signals transmitted by the first uplink radio frequency channel and the second uplink radio frequency channel is located between the two reference phases.

When the radio frequency signal is adjusted, and the adjusted phase is 360 degrees, the radio frequency signal is unchanged, so that when the predicted phase is determined, at least two predicted phases can be determined according to 360 degrees.

For example, the predicted phases are 0 degree, 90 degrees, 180 degrees, 270 degrees and 360 degrees, the 5 predicted phases are firstly adopted to adjust the radio frequency signals received by the first downlink radio frequency channel and/or the second downlink radio frequency channel, a plurality of total powers of the radio frequency signals of the first downlink radio frequency channel and the second downlink radio frequency channel are obtained, then two predicted phases corresponding to the first two total powers which are arranged from large to small are determined as reference phases according to the obtained plurality of total powers, then phases are repeatedly taken from the interval of the two reference phases, and the phases of the radio frequency signals of the first downlink radio frequency channel and/or the second downlink radio frequency channel are adjusted.

After the terminal obtains the multiple total powers through steps 701-703, the terminal determines a target phase difference of the radio frequency signals transmitted by the first uplink radio frequency channel and the second uplink radio frequency channel according to the obtained multiple total powers.

In this embodiment of the application, the terminal acquires at least two total powers through the above steps 701 to 703, and if the acquired total power is larger, it indicates that the phase difference between the radio frequency signals transmitted by the first uplink radio frequency access and the second uplink radio frequency access is smaller, so that the maximum total power is determined from the acquired at least two total powers, and the phase corresponding to the maximum total power is determined as the target phase difference between the radio frequency signals transmitted by the first uplink radio frequency access and the second uplink radio frequency access.

The phase control module may be a module included in a processor of the terminal or a module newly added in the terminal.

After the terminal completes the phase adjustment of the radio frequency signals of the first uplink radio frequency channel and/or the second uplink radio frequency channel, the influence of phase difference between the radio frequency signals of the first uplink radio frequency channel and the radio frequency signals of the second uplink radio frequency channel can be eliminated, and the transmitting power of the terminal cannot be influenced by the phase difference between the radio frequency signals of the first uplink radio frequency channel and the radio frequency signals of the second uplink radio frequency channel.

In the embodiment of the application, because the influence of the phase difference is eliminated between the radio frequency signal of the second uplink radio frequency channel and the radio frequency signal of the first uplink radio frequency channel, the two radio frequency signals cannot be offset in the overlapping process, and the effect of doubling the transmitting power of the terminal is ensured.

It should be noted that, in the embodiment of the present application, only the target phase difference is determined once, and the target phase difference is used to adjust the phase of the radio frequency signal of the first uplink radio frequency channel and/or the second uplink radio frequency channel, in another embodiment, the target phase difference may also be obtained again, and the used phase difference may also be updated.

The terminal continues to adjust the phase of the radio frequency signal of the first downlink radio frequency channel and/or the second downlink radio frequency channel, obtains the total power of the radio frequency signal of the adjusted first downlink radio frequency channel and the second downlink radio frequency channel, determines the phase difference of the radio frequency signal transmitted by the first uplink radio frequency channel and the second uplink radio frequency channel according to the obtained multiple total powers, and updates the phase difference to the target phase difference of the radio frequency signal transmitted by the first uplink radio frequency channel and the second uplink radio frequency channel, so that the terminal can execute step 705 by using the updated target phase difference.

The process executed again by the terminal is similar to the above steps 701-704, and is not described again here.
