It is to be understood that the data so used are interchangeable under appropriate circumstances so that the embodiments of the present application can be practiced in sequences other than those illustrated or described herein, and distinguish between "first", "second", etc. The objects are usually of one type, and the number of objects is not limited.

In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.

The communication network control method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Please refer to FIG. 1. FIG. 1 is a flowchart of a communication network control method provided by an embodiment of the present application. As shown in FIG. 1, the method includes the following steps:

Step 101: Under the condition that the first communication frequency band and the second communication frequency band are in working state, if it is detected that the signal blocking of the low noise amplifier occurs, preprocess the signal of the target communication frequency band; wherein, the target communication frequency band is the the first communication frequency band or the second communication frequency band.

It should be noted that, in the case where the frequency range of the first communication frequency band and the frequency range of the second communication frequency band are relatively close, if both the first communication frequency band and the second communication frequency band are in the working state, it is easy for the first communication frequency band to pair. The signal in the second communication frequency band is not sufficiently attenuated, causing the strong signal in the second communication frequency band to enter the Low Noise Amplifier (LNA) in the first communication frequency band, causing the LNA to block and reducing the first communication frequency. The communication quality of the frequency band. In addition, since the frequency range of the first communication frequency band and the frequency range of the second communication frequency band are relatively close, it is easy to cause large signal interference between the first communication frequency band and the second communication frequency band, affecting the first communication frequency band and the second communication frequency band. 2. The communication quality of the communication frequency band.

In the embodiment of the present application, when the first communication frequency band and the second communication frequency band are in working state, if it is detected that the low-noise amplifier is blocked, the target communication frequency band that causes the signal blocking of the low-noise amplifier needs to be preprocessed. To solve the signal blocking problem of the low noise amplifier. The target communication frequency band is the first communication frequency band or the second communication frequency band.

For example, the target communication frequency band is the first communication frequency band, assuming that the first communication frequency band is in the signal transmitting state, the second communication frequency band is in the signal receiving state, and the frequency range of the first communication frequency band is relatively separated from the frequency range of the second communication frequency band. In the near case, the transmission signal of the first communication frequency band may cause blockage of the low noise amplifier, then the transmission power of the first communication frequency band can be reduced to solve the blocking problem of the low noise amplifier and ensure the second communication frequency band. communication quality.

In an optional implementation manner, the step 101 may include:

Under the condition that the first communication frequency band and the second communication frequency band are in working state, obtain the received signal of the receiving end of the low noise amplifier;

In the case that the signal strength of the received signal is less than the preset signal strength, the transmit power of the target communication frequency band is reduced.

In this embodiment, when the first communication frequency band and the second communication frequency band are in the working state, the received signal received by the receiving end of the low-noise amplifier can be obtained, and the strength of the received signal can be used to determine whether the low-noise amplifier is Blocking occurs. For example, if it is detected that the signal strength of the received signal is lower than the preset signal strength, it means that the signal communication quality of the receiving end is poor at this time, it can be determined that the low noise amplifier is blocked at this time, and the transmit power of the target communication frequency band can be reduced. , in order to solve the blocking problem of the low-noise amplifier, ensure that the low-noise amplifier does not block the signal, and ensure the communication quality of the first communication frequency band and the second communication frequency band.

It should be noted that if it is detected that the LNA does not have signal blocking, the input signal of the target communication frequency band can be increased to increase the power to ensure the communication quality of the target communication frequency band. In this case, as long as there is no signal blocking Therefore, both the target communication frequency band and the non-target communication frequency band can ensure good communication quality.

Optionally, the preprocessing of the signal of the target communication frequency band may also include:

The digital filter is controlled to filter out the signal of the target communication frequency band and pass the signal of the non-target communication frequency band.

Wherein, when the target communication frequency band is the first communication frequency band, the non-target communication frequency band is the second communication frequency band; when the target communication frequency band is the second communication frequency band, the non-target communication frequency band is the second communication frequency band. is the first communication frequency band.

Understandably, in the signal receiving path of the communication structure, a digital filter is usually set to process the received signal to achieve the purpose of changing the frequency spectrum. In the embodiment of the present application, when it is detected that the low-noise amplifier has signal blocking, the digital filter may be controlled to filter out the signal of the target communication frequency band, so that the digital filter only passes the signal of the non-target communication frequency band, so that the target communication frequency band is allowed to pass. The fundamental wave can be processed in the digital domain to avoid the signal interference of the target communication frequency band to the non-target communication frequency band and ensure the communication of the non-target communication frequency band.

In an optional implementation manner of the embodiment of the present application, the first communication frequency band is an N79 frequency band, and the second communication frequency band is a wifi 5G frequency band. The following will take the N79 frequency band as the target communication frequency band and the wifi 5G frequency band as the non-target communication frequency band as examples to describe the above-mentioned embodiments in detail.

It should be noted that the frequency range of the N79 frequency band is 4400-5000MHz, and the frequency range of the wifi 5G frequency band is 5170-5835MHz. Referring to FIG. 1a, in the embodiment of the present application, when both the N79 frequency band and the wifi 5G frequency band are in the working state, for example, the N79 frequency band and the wifi 5G frequency band are in the receiving state, the fundamental wave of the transmitted signal of the N79 frequency band will enter the wifi 5G frequency band The low-noise amplifier LNA caused by the wifi 5G LNA is blocked. At this time, the digital filter that controls the wifi 5G frequency band can filter out the signal of the N79 frequency band, so that only the signal of the wifi 5G frequency band passes through the digital filter. Eliminate the interference of the fundamental wave of the N79 frequency band transmitted signal to the received signal of the wifi 5G frequency band, ensure the smooth signal of the wifi 5G frequency band, and also avoid the signal blocking of the low-noise amplifier in the wifi 5G frequency band, and ensure the smooth signal of the low-noise amplifier. .

The specific working principles and functions of the above components can be referred to related technologies, which will not be repeated in this embodiment.

Step 102: Control the power supply of the power amplifier to reduce the intermodulation component of the target communication frequency band.

It should be noted that a power amplifier is usually installed in the communication structure, and the nonlinearity of the power amplifier will generate rich intermodulation components. This will cause the signal-to-noise ratio of the second communication frequency band to decrease, and interfere with the communication quality of the second communication frequency band. After solving the signal blocking problem of the LNA, it is also necessary to solve the interference problem of the intermodulation component.

In the embodiment of the present application, after the signal of the target communication frequency band is preprocessed to solve the signal blocking problem of the low noise amplifier, the power supply of the power amplifier is controlled not to decrease, and the linearity of the power amplifier is adjusted to reduce the signal of the target communication frequency band. The intermodulation component is used to improve the interference problem of the intermodulation component of the target communication frequency band to the non-target communication frequency band and ensure the communication quality of the non-target communication frequency band.

Optionally, the step 102 may include:

The power supply of the power amplifier is controlled to increase or remain unchanged, and the linearity of the power amplifier is adjusted through the power amplifier linearization technology to reduce the intermodulation component of the target communication frequency band.

Understandably, after preprocessing the signal of the target communication frequency band, for example, reducing the transmit power of the target communication frequency band and solving the signal blocking problem of the low noise amplifier in the non-target communication frequency band, the Vcc of the power amplifier of the target communication frequency band can be increased. power supply, and adjust the linearity of the power amplifier through the power amplifier linearization technology, such as digital pre-distortion (Digital Pre-Distortion, DPD) technology (as shown in Figure 1b), to reduce the amplitude of the intermodulation signal in the target communication frequency band and The fundamental wave power remains unchanged, thereby improving the signal-to-noise ratio of the non-target communication frequency band, optimizing the signal sensitivity of the non-target communication frequency band, and ensuring the communication quality of the non-target communication frequency band. It should be noted that the DAC in FIG. 1b is a digital-to-analog converter, the modem is a modem, and the MIXER is a mixer. The specific working principles and functions of the above components can be referred to related technologies, which will not be repeated in this embodiment.

It should be noted that the first communication frequency band in the above embodiment may be in a signal receiving state or a signal transmitting state, and the second communication frequency band may be in a signal transmitting state or a signal receiving state, and the specific scenarios will not be repeated in this embodiment. .

The signal of the low noise amplifier is unobstructed, and then the power supply of the power amplifier is controlled, and the linearity of the power amplifier can be adjusted, thereby reducing the intermodulation component of the target communication frequency band. In this way, even when the two communication frequency bands with closely separated frequency ranges are both in working state, they can still have better uplink and downlink communication quality, ensure normal communication of electronic devices, and expand the communication application scenarios of electronic devices. , to bring users a better communication experience.
