[0002] For some peripheral IC devices of electronic devices (such as cameras and screens), the noise generated during operation will interfere with the main antenna of the electronic device, resulting in reduced communication quality and affecting the user experience. At this time, what can be done is to reduce the impact of the operation of peripheral IC devices on the electronic device through various measures.

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In addition, the term "and / or" in the present invention is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in the present invention generally indicates that the associated objects before and after are in an "or" relationship.

[0036] In order to solve the technical problems arising from the background technology, the embodiments of the present invention provide a method, apparatus, device and storage medium for suppressing interference of peripheral IC devices. Specifically, when the electronic device is in a communication state, the power of the radio frequency power amplifier of the electronic device is detected; according to the power of the radio frequency power amplifier, the power mode in which it is located is determined; if the power mode at the current moment is a high power mode, and the power mode at the previous moment is a low power mode, the operating frequency of the peripheral IC device in the working state of the electronic device is reduced; if the power mode at the current moment is a low power mode, and the power mode at the previous moment is a high power mode, the operating frequency of the peripheral IC device in the working state of the electronic device is increased.

[0037] In this way, the operating frequency of the peripheral IC device can be adaptively adjusted according to the power of the RF power amplifier, thereby solving the defect of the peripheral IC device maintaining frequency reduction and frame dropping for a long time while ensuring the communication quality.

[0038] In conjunction with the accompanying drawings, a method, apparatus, device and storage medium for suppressing interference of peripheral IC devices provided by the embodiments of the present invention are described in detail through specific embodiments.

[0039] First, the theoretical basis involved in the embodiments of the present invention is further explained:

[0040] (1) According to the communication protocol, when the signal obtained by the electronic device from the base station becomes weaker and weaker, the electronic device will increase the transmission power accordingly to ensure the communication quality. In view of this, the power mode (also known as gain mode) of the RF power amplifier (PA for short) is divided into low power mode (including L, M) and high power mode (H), wherein the power range corresponding to the L mode is -20~0db, the power range corresponding to the M mode is -3~13db, and the power range corresponding to the H mode is 11~23db. The intersection of the power ranges corresponding to the L mode, M mode, and H mode is the switching point. When the signal is good, the RF power amplifier is in low power mode, and when the signal is poor, the RF power amplifier is in high power mode. Exemplarily, the impact of peripheral IC devices on the communication of electronic devices can be shown as follows:

[0041] Peripheral IC devices work + electronic devices do not communicate = (no impact);

[0042] Peripheral IC device operation + electronic device communication + PA low power mode = (no impact);

[0043] Peripheral IC device operation + electronic device communication + PA high power mode = (impact, needs to be resolved).

[0044] (2) Working status of peripheral IC devices:

[0045] The peripheral IC devices work at the standard operating frequency (that is, the normal working frequency) + have no impact on the user experience + generate clutter that interferes with the communication of electronic equipment;

[0046] The peripheral IC devices work at a reduced frequency + which has a certain impact on the user experience but is within a controllable range + has little impact on the communication of electronic equipment.

[0047] To address this, an embodiment of the present invention provides a method for suppressing interference from peripheral IC devices, such as Figure 1 As shown, the method 100 may include the following steps:

[0048] S110, when the electronic device is in a communication state, detecting the power of a radio frequency power amplifier of the electronic device.

[0049] In some embodiments, it can be determined whether the electronic device is in a communication state. When the electronic device is in a communication state, the power of the RF power amplifier is detected in real time by a power detector connected to the RF power amplifier in the electronic device.

[0050] S120: Determine a power mode of the radio frequency power amplifier according to the power of the radio frequency power amplifier.

[0051] S130: If the power mode of the radio frequency power amplifier at the current moment is the high power mode and the power mode at the previous moment is the low power mode, then reduce the operating frequency of the peripheral IC device of the electronic device that is in a working state.

[0052] Specifically, if the power mode of the RF power amplifier is currently a high power mode and the power mode at the previous moment is a low power mode, the operating frequency of the peripheral IC device of the electronic device in operation is reduced to below its corresponding standard operating frequency.

[0053] It is worth noting that if the power mode of the RF power amplifier at the current moment is the high power mode, and the current moment is the first moment, and there is no power mode at the previous moment, then the operating frequency of the peripheral IC device of the electronic device in a working state is reduced to below its corresponding standard operating frequency; if the power mode of the RF power amplifier at the current moment is the high power mode, and the power mode at the previous moment was also the high power mode, then the peripheral IC device in a working state will not be frequency reduced.

[0054] It should be noted that before reducing the operating frequency of the peripheral IC device in the working state of the electronic device, a query message can be output to the user to ask whether the user agrees to reduce the frequency of the peripheral IC device to ensure the communication quality. If the frequency reduction confirmation message input by the user is received, the operating frequency of the peripheral IC device in the working state of the electronic device is allowed to be reduced. In this way, the user's current needs can be guided to further optimize the user experience.

[0055] S140: If the power mode of the radio frequency power amplifier at the current moment is the low power mode and the power mode at the previous moment is the high power mode, then increase the operating frequency of the peripheral IC device of the electronic device that is in a working state.

[0056] Specifically, if the power mode of the RF power amplifier is currently a low power mode and the power mode of the previous moment is a high power mode, the operating frequency of the peripheral IC device of the electronic device in operation is increased to its corresponding standard operating frequency.

[0057] It is worth noting that if the power mode of the RF power amplifier at the current moment is the low power mode, and the current moment is the first moment, and the power mode of the previous moment does not exist, then the peripheral IC device in the working state will not be up-converted; if the power mode of the RF power amplifier at the current moment is the low power mode, and the power mode of the previous moment was also the low power mode, then the peripheral IC device in the working state will not be up-converted.

[0058] It should be noted that the frequency modulation (up / down) of the peripheral IC device is achieved by using the driver interface of the peripheral IC device to control the peripheral IC device to call the frequency modulation parameters (up / down parameters).

[0059] In summary, according to the embodiments of the present invention, at least the following technical effects are achieved:

[0060] When the RF power amplifier is in high-power mode, it adaptively down-converts the working peripheral IC devices to reduce their driving capability, thereby ensuring the communication quality when the base station signal is weak; when the RF power amplifier is in low-power mode, it adaptively up-converts the working peripheral IC devices to restore their driving capability and ensure that users can use the peripheral devices normally. In this way, the operating frequency of the signal and the peripheral IC devices can be adjusted without affecting the work and use of users as much as possible (that is, the intermodulation frequency of the peripheral IC devices and TX does not fall within the generation of RX and does not cause interference).

[0061] The following takes a camera (cam_IC for short) in a common peripheral IC device as an example, and describes the method 100 provided by the embodiment of the present invention in detail in combination with a specific operating environment:

[0062] like Figure 2 As shown, the operating environment (ie, electronic device) includes PA, power detector, TR (ie, RF modem), CPU, and cam_IC connected in sequence. In this operating environment, cam_IC is in working state, and method 100 is specifically as follows:

[0063] When the electronic device is in the communication state, the power detector detects the power of the PA in real time. The power detector determines the power mode of the PA based on the power of the PA, and feeds back the power mode of the PA to the TR through the RF_POWER_DET pin. The TR feeds back the power mode of the PA to the CPU, and the CPU executes the following processing logic:

[0064] If the power mode of PA at the current moment is high power mode, and the current moment is the first moment, and there is no power mode at the previous moment, the operating frequency of cam_IC is reduced to below its corresponding standard operating frequency; if the power mode of PA at the current moment is high power mode, and the power mode at the previous moment is also high power mode, cam_IC is not frequency reduced; if the power mode of PA at the current moment is high power mode, and the power mode at the previous moment is low power mode, the operating frequency of cam_IC is reduced to below its corresponding standard operating frequency.

[0065] If the power mode of PA at the current moment is low power mode, and the current moment is the first moment, and there is no power mode at the previous moment, then cam_IC will not be frequency-upgraded; if the power mode of PA at the current moment is low power mode, and the power mode at the previous moment is also low power mode, then cam_IC will not be frequency-upgraded; if the power mode of PA at the current moment is low power mode, and the power mode at the previous moment was high power mode, then the operating frequency of cam_IC will be increased to its corresponding standard operating frequency.

[0066] It should be noted that the frequency modulation (up / down) of the cam device is completed by adjusting the parameters such as cam mipi_clk, cam_data transmission interval, cam data packet length, etc. in the driver interface of cam_IC. Figure 3 shown.

[0067] It should be noted that, for the above-mentioned method embodiments, for the sake of simplicity, they are all described as a series of action combinations, but those skilled in the art should know that the present invention is not limited by the described order of actions, because according to the present invention, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also know that the embodiments described in the specification are all optional embodiments, and the actions and modules involved are not necessarily required by the present invention.
