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, and a character "/" generally means that the former and latter related objects are in an "or" relationship.
In the frequency band interference processing method provided in the embodiment of the present application, the execution main body may be a frequency band interference processing device, or a control module in the frequency band interference processing device, configured to execute the frequency band interference processing method.
The frequency band interference processing apparatus in the embodiment of the present application may be an apparatus, or may also be a component, an integrated circuit, or a chip in a terminal. The device can be mobile electronic equipment or non-mobile electronic equipment. By way of example, the mobile electronic device may be a mobile phone, a tablet computer, a notebook computer, a palm top computer, a vehicle-mounted electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the like, and the non-mobile electronic device may be a server, a Network Attached Storage (NAS), a Personal Computer (PC), a Television (TV), a teller machine or a self-service machine, and the like, and the embodiments of the present application are not particularly limited.
The frequency band interference processing apparatus in the embodiment of the present application may be an apparatus having an operating system. The operating system may be an Android operating system, an iOS operating system, or other possible operating systems, which is not specifically limited in the embodiment of the present application.
The frequency band interference processing method, the frequency band interference processing apparatus, the electronic device, the readable storage medium, and the chip 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.
Fig. 1 is a flowchart of a frequency band interference processing method provided in an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:
step 101: under the condition that the clock signal of the first frequency interferes with the first channel, judging whether the clock signal of the second frequency interferes with the second channel; the first channel is a channel used by a first communication frequency band, the second channel is a channel used by a second communication frequency band, and the first communication frequency band and the second communication frequency band are in a communication connection state at the same time.
Here, the Clock (CLK) signal may also be referred to as a MIPI Clock signal or a MIPI signal, and is a signal when data is transmitted between a peripheral device such as a camera, a liquid crystal display, etc. of a Mobile Industry Processor Interface (MIPI) and a Processor. The clock signal is usually longer in transmission path, so that interference to radio frequency communication is easily caused, communication signal is reduced, and the experience of a user in conversation and surfing the internet is influenced.
Whether the clock signal causes interference to radio frequency communication or not is related to the frequency of the clock signal and the frequency point corresponding to the channel. For example, the frequency of the MIPI clock signal is f0=580MHz, and its harmonics 2f0, 3f0, 4f0, etc. would interfere if overlapped with the frequency of the radio frequency signal, where, for example, 4 th harmonic is 4f0=2320MHz, and falls within the B40 [ 2300, 2400MHz ] band, and if the operating bandwidth of the communication channel includes the frequency point of 2320MHz, its 4 th harmonic would interfere with the communication channel.
In the embodiment of the present application, the clock signal may be a digital clock signal, such as a clock signal generated by a crystal, or an analog clock signal, such as an OSC generated by an RC oscillation circuit.
In the embodiment of the present application, it is necessary to acquire a channel used by each communication frequency band, and also to acquire a frequency of a clock signal of a first frequency. After acquiring the information, the electronic device may determine whether the clock signal of the first frequency interferes with each communication frequency band according to the information. Specifically, the electronic device may know the frequency of the clock signal during operation in real time, and the electronic device may also obtain channel information of the communication frequency band in real time, where the channel information corresponds to the frequency, and then the electronic device may compare the obtained channel frequency information with harmonic frequency information of the clock signal, and if the frequencies overlap, it may be determined that the clock signal interferes with the communication frequency band, and if the frequencies do not overlap, it may be determined that the clock signal does not interfere with the communication frequency band.
In the embodiment of the present application, the clock signal with the first frequency may be understood as the current clock signal, that is, the frequency of the current clock signal is the first frequency, and the second frequency may be understood as the pre-switching frequency of the clock signal. Because the clock signal of the first frequency interferes with the channel used by the first communication frequency band, the clock signal of the second frequency generally does not interfere with the channel used by the first communication frequency band, and therefore, if the clock signal is switched from the first frequency to the second frequency, the problem of interference of the clock signal with the first communication frequency band can be solved.
In the prior art, for an electronic device for single-band communication, when a clock signal interferes with a channel, the clock signal is usually switched to other frequencies. For electronic equipment of multi-band communication, when a clock signal interferes with a channel, a system priority strategy is often adopted, for example, under the condition of LTE + NR dual link, an LTE frequency band can be preferentially adopted for judgment, interference on the LTE frequency band can be avoided, but interference on an NR frequency band cannot be considered; or, the NR frequency band may be preferentially adopted for determination, so that interference to the NR frequency band may be avoided, but interference to the LTE frequency band may not be considered at the same time.
As can be seen, for an electronic device with multi-band communication, for example, simultaneous communication between a first communication band and a second communication band, considering that if a clock signal is switched from a first frequency to a second frequency, the problem of interference of the clock signal to the first communication band can be theoretically solved, but the problem of interference of the clock signal to the second communication band may be brought about, in view of this, the embodiment of the present application further performs a re-determination on the second communication band, that is, determines whether the clock signal of the second frequency interferes with a second channel.
Step 102: and if the clock signal of the second frequency is judged not to generate interference on the second channel, switching the frequency of the clock signal from the first frequency to the second frequency.
In this step, the frequency of the clock signal may be switched from the first frequency to the second frequency when it is determined that the clock signal of the second frequency does not interfere with the second channel.
In this embodiment of the application, specific frequency bands of the first communication frequency band and the second communication frequency band are not limited, for example, under an NSA architecture, the electronic device needs to connect the NR frequency band and the LTE frequency band at the same time, so the first communication frequency band may be one of the LTE frequency band and the NR frequency band, and the second communication frequency band may be the other of the LTE frequency band and the NR frequency band. The frequency points of the first communication frequency band and the second communication frequency band are not fixed, and the number of channels of the first communication frequency band and the second communication frequency band is not limited. The priority of the first communication band and the priority of the second communication band are not limited, and the priority of the first communication band may be higher than the priority of the second communication band or lower than the priority of the second communication band.
The embodiment of the present application is not only applicable to the NSA system, but also applicable to a dual link system in which a combination of 2G, 3G, 4G, and 5G technologies exists.
In addition, the technical solution of the present application is described based on the first communication frequency band and the second communication frequency band in the embodiments of the present application, but the present application is not limited to the electronic device with only the first communication frequency band and the second communication frequency band, and may also be applied to electronic devices with more communication frequency bands for simultaneous communication.
In the embodiment of the application, for a multi-band communication scenario, when a clock signal of a first frequency interferes with a certain communication band, the interference of the clock signal of the first frequency to the communication band is no longer considered, but after the interference of the communication band is judged, other communication bands are also judged again, so that the switching of the clock signal frequency is ensured not to affect another communication band. Therefore, the embodiment of the application can give consideration to a plurality of communication frequency bands, so that the switched clock signal can not interfere with the plurality of communication frequency bands, and the radio frequency communication performance of the electronic equipment is improved.
Optionally, the priority of the second communication frequency band is greater than the priority of the first communication frequency band.
In this embodiment, in the interference processing of the clock signal to the communication frequency band, the priority of the communication frequency band may be further considered to determine the switching manner of the clock signal frequency more reasonably, and specifically, when the clock signal of the first frequency interferes with the communication frequency band with a lower priority (i.e., the first communication frequency band), it is necessary to ensure that the switched clock signal does not interfere with the communication frequency band with a higher priority (i.e., the second communication frequency band). Therefore, the communication frequency band with high priority can be preferentially ensured not to be interfered by the clock signal, and the clock signal can be switched more reasonably.
Optionally, in a case that the clock signal of the first frequency interferes with the first channel, the method further includes:
and if the clock signal with the second frequency is judged to generate interference on the second channel, maintaining the frequency of the clock signal at the first frequency.
In this embodiment, if the clock signal of the first frequency interferes with the first channel, but the clock signal of the pre-switched second frequency interferes with the second channel, the frequency of the clock signal is maintained at the first frequency even if the clock signal of the first frequency interferes with the first channel.
Further, when the priority of the second communication band is higher than the priority of the first communication band, if it is determined that the clock signal of the second frequency interferes with the second channel, the frequency of the clock signal is maintained at the first frequency.
In addition, under the condition that more clock signal frequencies can be set, the frequency of the clock signal can also be other frequencies such as a third frequency and a fourth frequency, and then, under the condition that the clock signal of the first frequency interferes with the first channel and the clock signal of the second frequency interferes with the second channel, whether the clock signal of other frequencies such as the third frequency interferes with the second channel or not can be continuously judged, and so on until the clock signal frequency which does not interfere with the first channel or the second channel is found.
Optionally, the method further includes:
and switching the frequency of the clock signal from the first frequency to the second frequency under the condition that the clock signal of the first frequency generates interference on the second channel.
Further, in the case that the priority of the second communication band is greater than the priority of the first communication band, once the clock signal of the first frequency interferes with the second channel, the frequency of the clock signal may be directly switched from the first frequency to the second frequency without considering whether the switched clock signal interferes with the first channel. Therefore, the communication frequency band with higher priority can ensure better communication effect as much as possible, so as to ensure the radio frequency communication performance of the electronic equipment.
Further, it is considered that when a high priority communication band is considered more preferentially, a low priority communication band may cause more serious interference. For example, assuming that the clock signal of the first frequency causes slight interference to the second channel and does not interfere with the first channel, and the clock signal of the second frequency does not interfere with the second channel but interferes with the first channel seriously, a situation may occur in which the interference of the first communication band is solved to cause serious interference to the first communication band.
Therefore, the embodiment of the present application further provides the following implementation manner to further improve the frequency band interference processing scheme in the multi-band communication scenario.
Optionally, switching the frequency of the clock signal from the first frequency to the second frequency when the clock signal of the first frequency interferes with the second channel includes:
under the condition that the clock signal of the first frequency generates interference on the second channel, judging whether the clock signal of the second frequency generates interference on the first channel or not;
if the clock signal of the second frequency is judged not to generate interference on the first channel, switching the frequency of the clock signal from the first frequency to the second frequency;
if the clock signal of the second frequency is judged to generate interference on the first channel, judging whether the interference intensity of the clock signal of the second frequency on the first channel is greater than the interference intensity of the clock signal of the first frequency on the second channel;
and if the interference strength of the clock signal with the second frequency to the first channel is judged to be less than or equal to the interference strength of the clock signal with the first frequency to the second channel, switching the frequency of the clock signal from the first frequency to the second frequency.
In this embodiment, when the clock signal of the first frequency interferes with the second channel, the influence of the clock signal of the first frequency on the second channel and the influence of the clock signal of the second frequency on the first channel are further considered, instead of directly switching the frequency of the clock signal from the first frequency to the second frequency.
The following description will be made separately in two cases.
First, the clock signal of the second frequency does not interfere with the first channel, which means that neither the clock signal of the second frequency interferes with the first channel or the second channel, and therefore, the clock signal can be switched from the first frequency to the second frequency.
Secondly, the clock signal of the second frequency generates interference on the first channel, but the interference strength of the clock signal of the second frequency on the first channel is less than or equal to the interference strength of the clock signal of the first frequency on the second channel, which indicates that the interference influence of the clock signal of the second frequency on the whole communication frequency band is smaller, and therefore, the clock signal can be switched from the first frequency to the second frequency.
The embodiment is not only applicable to the case where the priority of the communication frequency band is not considered, but also better applicable to the case where the priority of the second communication frequency band is greater than the priority of the first communication frequency band, and is not described in detail to avoid repetition.
In this embodiment, by further considering the interference strength of the clock signal to each communication frequency band, the interference of the clock signal to the multi-band communication system can be equalized to the greatest extent, and the radio frequency performance of each communication frequency band can be considered at the same time.
Further, in determining the interference strength of the clock signal to the communication frequency band, the interference strength of the communication frequency band may be classified as follows: dividing the interference intensity into three levels of strong interference, slight interference and no interference by setting a first threshold and a second threshold, wherein the first threshold is 10, the second threshold is 1, and when the interference intensity exceeds 10dB, the level of the strong interference is corresponded; when the interference strength is between 1 and 10dB, corresponding to a slight interference level; when the interference strength is less than 1dB, the interference-free level is corresponded.
In this way, if the interference strength of the clock signal of the second frequency to the first channel is a slight interference and the interference strength of the clock signal of the first frequency to the second channel is a strong interference, the interference strength of the clock signal of the second frequency to the first channel may be considered to be smaller than the interference strength of the clock signal of the first frequency to the second channel. If the interference strength of the clock signal of the second frequency to the first channel is slight interference (or strong interference) and the interference strength of the clock signal of the first frequency to the second channel is slight interference (or strong interference), the interference strength of the clock signal of the second frequency to the first channel can be considered to be equal to the interference strength of the clock signal of the first frequency to the second channel.
In this embodiment, the interference strength of the communication band is classified, so that the judgment of the interference strength of the clock signal on the communication band is simpler.
Optionally, the method further includes:
and if the interference strength of the clock signal with the second frequency to the first channel is judged to be greater than the interference strength of the clock signal with the first frequency to the second channel, maintaining the frequency of the clock signal at the first frequency.
Under the condition of grading the interference strength of the communication frequency band, if the interference strength of the clock signal of the second frequency to the first channel is strong interference and the interference strength of the clock signal of the first frequency to the second channel is slight interference, the interference strength of the clock signal of the second frequency to the first channel can be considered to be greater than the interference strength of the clock signal of the first frequency to the second channel.
In this embodiment, avoidance of interference on the second channel can be avoided, and more severe interference on the first channel can be introduced.
Optionally, if it is determined that the clock signal with the second frequency interferes with the second channel, maintaining the frequency of the clock signal at the first frequency includes:
if the clock signal of the second frequency is judged to generate interference on the second channel, judging whether the interference intensity of the clock signal of the second frequency on the second channel is greater than or equal to the interference intensity of the clock signal of the first frequency on the first channel;
and if the interference strength of the clock signal with the second frequency to the second channel is judged to be greater than or equal to the interference strength of the clock signal with the first frequency to the first channel, maintaining the frequency of the clock signal at the first frequency.
In this embodiment, when the clock signal of the second frequency interferes with the second channel, the influence of the clock signal of the second frequency on the second channel and the influence of the clock signal of the first frequency on the first channel are further considered, without directly giving up switching the frequency of the clock signal.
Specifically, even if the clock signal of the first frequency interferes with the first channel and the clock signal of the second frequency interferes with the second channel, if the interference strength of the clock signal of the second frequency with the second channel is greater than or equal to the interference strength of the clock signal of the first frequency with the first channel, the frequency of the clock signal is maintained at the first frequency so as not to introduce more serious interference.
Optionally, the method further includes:
and if the interference strength of the clock signal with the second frequency to the second channel is judged to be smaller than the interference strength of the clock signal with the first frequency to the first channel, switching the frequency of the clock signal from the first frequency to the second frequency.
In this embodiment, even if the clock signal of the first frequency interferes with the first channel and the clock signal of the second frequency interferes with the second channel, if the interference strength of the clock signal of the second frequency with the second channel is smaller than the interference strength of the clock signal of the first frequency with the first channel, the clock signal may be switched from the first frequency to the second frequency in order to reduce the interference influence of the clock signal on the entire communication band.
It should be noted that, in the embodiment of the present application, various optional implementations of the frequency band interference processing method may be implemented in combination with each other, or may be implemented separately, and the present application is not limited thereto.
In the embodiment of the application, for a multi-band communication scenario, when a current clock signal interferes with a certain communication band, the interference of the current clock signal to the communication band is not considered any more, but after the interference of the communication band is judged, other communication bands are also judged again, so that the switching of the clock signal frequency does not affect another communication band. Therefore, the embodiment of the application can give consideration to a plurality of communication frequency bands, so that the switched clock signal can not interfere with the plurality of communication frequency bands.
It should be noted that, in the frequency band interference processing method provided in the embodiment of the present application, the execution main body may be a frequency band interference processing device, or a control module used for executing the frequency band interference processing method in the frequency band interference processing device.
