Detailed Description

In order to enable those skilled in the art to better understand the present application, the following description will make clear and complete descriptions of the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.

Ultra Wide Band (UWB): the wireless transmission is realized by sending and receiving extremely narrow pulses with nanoseconds or microseconds or less, so that the wireless transmission has ultra-large bandwidth and low transmitting power, and rapid data transmission on a low power consumption level can be further realized. UWB technology is widely used in a variety of contexts due to its advantages described above.

With the development of urban construction, the dense degree of urban architecture is larger and larger, and the accurate positioning and navigation requirements for the dense architecture area are stronger and stronger. However, the positioning accuracy of the conventional global navigation satellite system (Global Navigation Satellite System, GNSS) navigation between urban buildings is poor, often deviates by several meters or even tens of meters, especially when the passengers are about to get on the road, because the passengers are often inside or under the high building, GNSS positioning often leads the driver of the car to be misled to the opposite road, even on the nearby street, which causes a lot of inconvenience.

Since UWB technology has extremely strong interference immunity, and UWB technology can provide accurate positioning on the millimeter level in indoor/building/street or the like by way of TDOA/PDOA. Therefore, during the laying process of the positioning network, a large number of UWB anchor points are usually laid on the basement of a wall, so as to be applied to wireless network access and positioning of each UWB terminal in an indoor/building/street and the like.

However, other communication modules, such as a 4G (fourth generation mobile communication technology, the 4th generation mobile communication technology) communication module, a 5G (fifth generation mobile communication technology, the 5th generation mobile communication technology) communication module, and other modules for cellular communication, such as a WIFI module, are commonly present in electronic devices. When the electronic device uses the communication modules to communicate at the same time, interference between networks may exist, thereby affecting the working state of the networks. The interference between UWB and other communications is typically harmonic interference or adjacent channel interference.

The harmonic interference is that the harmonic of one communication system (low frequency band) falls into the working frequency band of another communication system (high frequency band), so that the working of the other communication system is affected, when the harmonic of A falls into the working frequency band of B, the harmonic of A is usually A to interfere B, but B does not interfere A, therefore, the reason for generating the harmonic interference may be that the frequency multiplication range of the communication frequency band of other communication is overlapped with the frequency range of UWB; the adjacent frequency interference refers to that the working frequency bands of one communication system are similar to that of the other communication system, the two communication systems can mutually influence each other when working, and when the working frequency bands of A and B are similar, the interference A is usually that the interference B and the interference B also interfere A.

In the related art, for harmonic interference between UWB and other communications, a filter is generally added in a radio frequency transmission path of other communications modules to suppress interference of the harmonic to a UWB network, for example, as shown in fig. 1, by adding a filter to a radio frequency path of Cellular to suppress mutual interference between UWB and Cellular; for adjacent frequency interference between UWB and other communications, the isolation of the antennas between the two is usually increased (by increasing the spatial distance) to solve the mutual interference between UWB and adjacent frequency bands of other communications. However, these methods require additional components or an increased internal space of the electronic device to reduce the interference, and thus increase the cost and the volume of the electronic device.

In view of the above problems, the inventor proposes a communication processing method, an apparatus, an electronic device, and a storage medium provided by the embodiments of the present application, which can determine whether there is interference according to a channel of ultra-wideband communication and a working frequency band of target communication when the electronic device enables the ultra-wideband communication and the target communication at the same time, and reduce interference between the ultra-wideband communication and the target communication by switching the working channel of the ultra-wideband communication when the interference exists, thereby improving communication performance and effect of the electronic device. The specific communication processing method is described in detail in the following embodiments.

The following describes a hardware environment to which the communication processing method provided in the embodiment of the present application is applied.

Referring to fig. 2, fig. 2 shows a schematic structural diagram of an electronic device provided in an embodiment of the present application, and the electronic device 100 may include an AP (application processor ) module 11, a UWB chip 12, a Cellular chip 13, and a WIFI chip 14. The UWB chip 12, the Cellular chip 13 and the WIFI chip 14 are all connected with the AP module 11, and the UWB chip 12, the Cellular chip 13 and the WIFI chip 14 can report respective communication information to the AP module 11 of the CPU chip, and the AP module can issue command control to these communication chips. The AP module 11 may be a central processing unit (Central Processing Unit, CPU) or the like; the communication information may include a communication status, such as an operating frequency band, a signal strength, etc., without limitation, so that the AP module 11 can acquire the status of the communication chips and control the communication chips. Of course, other communication chips may also be included in the electronic device 100, such as a Bluetooth chip, zigbee chip, and the like.

The following describes in detail a communication processing method provided in an embodiment of the present application with reference to the accompanying drawings.

Referring to fig. 3, fig. 3 is a flow chart illustrating a communication processing method according to an embodiment of the present application. In a specific embodiment, the communication processing method is applied to a communication processing apparatus 400 as shown in fig. 10 and an electronic device 100 (fig. 11) configured with the communication processing apparatus 400. The specific flow of the embodiment will be described below by taking an electronic device as an example, and it will be understood that the electronic device applied in the embodiment may be a smart phone, a tablet computer, a smart watch, etc., which is not limited herein. The following details about the flow shown in fig. 3, the communication processing method specifically may include the following steps:

step S110: and under the condition that the electronic equipment enables ultra-wideband communication and target communication, acquiring a working channel of the ultra-wideband communication and a working frequency band of the target communication.

In the embodiment of the application, the electronic device may acquire the working states of the communication modules in real time, so as to reduce the possible mutual interference between UWB communication and target communication in the electronic device when the UWB communication module and the target communication module are simultaneously turned on, that is, UWB communication and target communication are simultaneously enabled. The target communication may be other communication than ultra-wideband communication, for example, may be cellular communication, WIFI communication, bluetooth communication, etc., and the electronic device may determine for interference between UWB communication and other communication; the electronic device may also be UWB communication, optionally, at least two UWB modules are included in the electronic device, when the at least two UWB modules are enabled to communicate, the electronic device may also determine interference between UWB communications, for example, when two UWB modules are simultaneously enabled, the channels used by the two UWB modules are the same, and interference may exist, where interference needs to be avoided and reduced. Under the condition that any one of UWB communication and target communication is determined to be simultaneously started, the electronic equipment acquires a working channel of the ultra-wideband communication and a working frequency band of the target communication so as to determine whether interference exists between the UWB communication and the target communication; that is, the electronic device can acquire the operating channel of UWB communication and the operating band of target communication as long as at least two kinds of communication are simultaneously enabled and UWB communication is included in the at least two kinds of communication. It will be appreciated that UWB communications typically have a plurality of operating channels, and that the frequency ranges of the different operating channels are different, and that other communications are operating in corresponding frequency bands, such that there is a frequency range corresponding to the operating channel of UWB communications, and when the corresponding conditions are met between the operating frequency band of the target communications, there may be interference between UWB communications and the target communications, and thus, a determination may be made regarding the interference that may occur within the electronic device.

In some embodiments, the electronic device may enable UWB communication and target communication simultaneously in multiple scenarios, for example, when the electronic device is used in an augmented reality (Augmented Reality, AR) scenario, the electronic device may enable UWB communication and WIFI communication simultaneously, thereby positioning a real scenario through UWB communication and acquiring AR resource content through WIFI communication; for another example, the electronic device is used for playing music through the connected bluetooth headset, and when the electronic device is used for a scene of indoor positioning, the electronic device simultaneously starts UWB communication and bluetooth communication, so that positioning by using UWB can be realized, and music can be output by using the bluetooth headset. Of course, the specific scenario in which the electronic device simultaneously enables UWB communication and target communication may not be limited.

In some embodiments, the processor of the electronic device may obtain the operating channel in which it is located from the UWB communication module and obtain the operating frequency band of the communication module corresponding to the target communication. Of course, the electronic device may control the operating system to enter a setting mode, so that the operating channel of UWB communication in an operating state and the operating frequency band of target communication may be obtained, and the setting mode may be an engineering mode corresponding to the operating system, which is not limited herein.

Step S120: and determining that interference exists between the ultra-wideband communication and the target communication based on the frequency band corresponding to the working channel and the working frequency band, wherein the frequency bands corresponding to different working channels are different.

In this embodiment of the present application, after the electronic device obtains the working channel of UWB communication and the working frequency band of the target communication, whether interference exists between the UWB communication and the target communication may be determined based on the frequency band (frequency range) and the working frequency band corresponding to the obtained working channel, so as to perform corresponding processing when it is determined that interference exists between the UWB communication and the target communication, thereby reducing interference between the UWB communication and the target communication.

In some embodiments, the electronic device may determine, according to the different interference types, whether the two meet the interference condition of any interference type based on the frequency band corresponding to the working channel and the working frequency band of the target communication. It will be appreciated that the interference conditions corresponding to the different interference types are different, and whether any type of interference exists between the UWB communication and the target communication can be determined based on the interference conditions, the frequency band of the UWB communication, and the operating frequency band of the target communication. For example, for harmonic interference, it may be determined whether a multiple of the operating frequency band of the target communication falls within the frequency band of the UWB communication, thereby determining whether harmonic interference exists between the UWB communication and the target communication.

When the above-mentioned target communication is plural, that is, when the electronic device has enabled plural communications in addition to UWB communication, the processing of step S110 and step S120 may be executed for each of the target communications, respectively, to determine whether or not there is interference between the UWB communication and each of the target communications, and to perform the corresponding processing based on the determination result.

Step S130: and switching an operating channel of the ultra-wideband communication in response to interference between the ultra-wideband communication and the target communication.

In the embodiment of the application, under the condition that the electronic device determines that the interference exists between the UWB communication and the target communication, in order to reduce the interference existing between the UWB communication and the target communication, the working channel of the UWB communication can be switched. The electronic device switches the working channel of the UWB communication, and can switch the working channel of the UWB communication to other channels according to the existing interference type, so that the UWB communication and the target communication are theoretically free of interference, and the possibility of interference between the UWB communication and the target communication is reduced.

In some embodiments, mapping tables corresponding to different interference types may be stored in the electronic device, where the mapping tables store selectable working channels of UWB communications in each possible working frequency band, and the selectable working channels can ensure that communication interference of the interference type does not exist between UWB communications and the target communications. The electronic device may switch the operating channel of the UWB communication to a selectable operating channel based on the mapping table. For example, as shown in the table below, which shows a mapping table corresponding to harmonic interference,

Of course, this table is merely an exemplary illustration of the mapping table correspondence for harmonic interference.

In other embodiments, when the electronic device responds to the existence of interference between the UWB communication and the target communication, it may determine, in turn, for each of the other operating channels of the UWB communication, whether there is interference between the electronic device and the target communication, that is, whether there is interference based on the frequency band corresponding to each of the other operating channels and the operating frequency band of the target communication, so as to determine a channel to which there is no interference, and use the channel as the operating channel to be switched. Wherein the other working channels are working channels except the current working channel in the communication channels of UWB communication. Of course, the specific manner in which the electronic device switches the operating channel of the UWB communication in response to the presence of interference between the UWB communication and the target communication may not be limited, and only after the channel of the UWB communication is adjusted, there is no interference between the UWB communication and the target communication.

In some embodiments, the target communication that may be enabled by the electronic device may include multiple communications, in which case, when the electronic device switches the operating channel of the UWB communication, a channel corresponding to a frequency band where no interference exists in each communication may be determined according to the operating frequency band of each communication in the target communication, and the operating channel of the UWB communication is switched to the determined operating channel, so that interference between the UWB communication and the target communication can be avoided theoretically.

In one possible implementation, in some cases, it may not be possible to determine a channel corresponding to a frequency band where each communication is not interfered. At this time, in order to smoothly determine the adjustable working channel, the working frequency band of the target communication may be adjusted, and after the working frequency band is adjusted, the channel corresponding to the frequency band where no interference exists in each communication is determined. For example, when the target communication includes cellular communication and WIFI communication, the frequency band corresponding to the working channel of UWB is 4441.2-4940.4MHz, the working frequency band of WIFI communication is 4920-4930MHz, and the working frequency band of cellular communication is 2320-2370MHz, at this time, adjacent frequency interference exists between UWB communication and WIFI communication, and harmonic interference exists between UWB communication and cellular communication, so that no interference exists between UWB communication and WIFI communication and between cellular communication. Under the condition that no selectable channel exists in the communication channel of the UWB, the UWB communication, the WIFI communication and the cellular communication can be enabled to be free of interference at the same time, under the condition that the working frequency band of the WIFI communication can be changed through the electronic equipment, the working frequency band is one of 5GHz frequency bands (5925-7125 MHz), at the moment, the channel 9 (7489.6-8489.6 MHz) can be found, and therefore the adjacent frequency interference between the UWB communication and the WIFI communication can be avoided while the harmonic interference between the UWB communication and the cellular communication can be effectively avoided. Optionally, if the target communication includes a communication that cannot directly change the operating frequency, the operating frequency may also be changed by the electronic device requesting resources, so that the electronic device can switch the operating channel of UWB to a suitable operating channel, for example, the target communication includes cellular communication, and at this time, the base station may be requested to schedule resources so that the frequency band of the cellular communication is adjusted.

According to the communication processing method provided by the embodiment of the application, whether interference exists or not can be determined according to the channel of the ultra-wideband communication and the working frequency range of other communication under the condition that the ultra-wideband communication and the target communication are simultaneously started by the electronic equipment, and the interference between the ultra-wideband communication and the target communication is reduced by switching the working channel of the ultra-wideband communication under the condition that the interference exists, so that the communication performance and the effect of the electronic equipment are improved, and the communication effect of UWB communication is improved.

Referring to fig. 4, fig. 4 is a flow chart illustrating a communication processing method according to another embodiment of the present application. The communication processing method is applied to the electronic device, and will be described in detail with respect to the flow shown in fig. 4, and the communication processing method specifically includes the following steps:

step S210: and under the condition that the electronic equipment enables ultra-wideband communication and target communication, acquiring a working channel of the ultra-wideband communication and a working frequency band of the target communication.

In the embodiment of the present application, step S210 may refer to the content of other embodiments, which is not described herein.

Step S220: and determining that harmonic interference or adjacent frequency interference exists between the ultra-wideband communication and the target communication based on the frequency band corresponding to the working channel and the working frequency band, wherein the frequency bands corresponding to different working channels are different.

In the embodiment of the application, the interference between the ultra-wideband communication and the target communication mainly comprises harmonic interference and adjacent frequency interference, and when the electronic equipment determines the interference between the ultra-wideband communication and the target communication, whether the harmonic interference or the adjacent frequency interference exists between the ultra-wideband communication and the target communication or not can be determined based on the frequency band corresponding to the working channel of the ultra-wideband communication and the working frequency band of the target communication, so that when the harmonic interference or the adjacent frequency interference exists between the ultra-wideband communication and the target communication is determined, the communication of the electronic equipment is processed. The electronic device may determine whether harmonic interference exists between the ultra-wideband communication and the target communication based on a condition of the harmonic interference, and determine whether adjacent channel interference exists between the ultra-wideband communication and the target communication based on a condition of the adjacent channel interference.

In some embodiments, referring to fig. 5, determining, by the electronic device, that harmonic interference or adjacent channel interference exists between the ultra-wideband communication and the target communication based on the frequency band corresponding to the operating channel and the operating frequency band may include:

step S221: if the frequency multiplication range of the target communication is determined to be overlapped with the frequency band corresponding to the working channel based on the working frequency band, harmonic interference exists between the ultra-wideband communication and the target communication.

In this embodiment, since the frequency of the frequency band of each channel of UWB communication is high, it is common that the harmonic wave of the target communication falls within the frequency band of UWB communication, and harmonic interference is caused to UWB communication. Thus, the electronic device can determine whether there is coincidence of the frequency range of the target communication with the frequency band corresponding to the operating channel to determine whether the target communication produces harmonic interference to the UWB communication.

Optionally, the electronic device may acquire, based on the operating frequency band, a frequency multiplication range of uplink communication or a frequency multiplication range of downlink communication of the target communication as the first frequency range; acquiring a frequency range of downlink communication corresponding to a working channel as a second frequency range; if the first frequency range and the second frequency range are coincident, harmonic interference between the ultra-wideband communication and the target communication is determined. It can be understood that the frequency range of the uplink communication of the normal communication is the same as the frequency range of the downlink communication, so that the frequency multiplication range of the uplink communication or the frequency multiplication range of the downlink communication of the target communication can be obtained based on the operating frequency band of the target communication. Also, harmonic interference is generally generated because the operating frequency range of one communication falls into the downstream frequency range of another communication, and thus the frequency range of the downstream communication of UWB communication can also be acquired. And then judging whether the frequency multiplication range is overlapped with the frequency range of the downlink communication of the UWB communication or not, if so, indicating that harmonic interference exists between the target communication and the UWB communication, and if not, indicating that no harmonic interference exists between the target communication and the UWB communication. For example, as shown in fig. 6, the frequency range of the UWB downlink communication is 5989.6 to 6989.6MHz; the target communication is cellular communication, the frequency range of which is 3300-3400 MHz, the frequency multiplication range is 6600-6800 MHz, and the frequency range of 5989.6-6989.6 MHz comprises the frequency range of 6600-6800 MHz, so that the current cellular communication can be determined to cause harmonic interference to UWB communication.

Step S222: and if the frequency based on the interval between the frequency band corresponding to the working channel and the working frequency band is smaller than the preset frequency, determining that adjacent frequency interference exists between the ultra-wideband communication and the target communication.

In this embodiment, the electronic device may acquire the frequency of the interval between the frequency band corresponding to UWB communication and the operating frequency band of target communication. For example, the working frequency band of the target communication is 5925-7125 MHz, the corresponding frequency band of the working channel of the UWB communication is 5989.6-6989.6 MHz, and the frequency band of 5925-7125 MHz contains the frequency band of 5989.6-6989.6 MHz, and the interval frequency of the two is 0; for another example, the frequency band corresponding to the UWB operation channel is 4441.2-4940.4 MHz, and the wifi operation frequency band is 4943-4953MHz, and the interval frequency between them is: 4943-4940.4 =2.6 Hz. After the electronic equipment acquires the frequency of the interval between the frequency band corresponding to the UWB communication and the working frequency band of the target communication, the interval frequency can be compared with the preset frequency, and if the interval frequency is smaller than the preset frequency, the adjacent frequency interference exists between the UWB communication and the target communication; otherwise, if the frequency of the interval is not smaller than the preset frequency, the condition that adjacent frequency interference does not exist between UWB communication and target communication is indicated. The specific value of the preset frequency is not limited, and may be, for example, 2Hz, 5Hz, 10Hz, etc.

It can be understood that the above-mentioned frequency interval is smaller than the preset frequency, and includes two cases, wherein one case is that there is overlap between the frequency band corresponding to the operating channel of UWB communication and the operating frequency band of target communication, that is, the frequency interval is 0; alternatively, the frequency of the interval between the frequency band corresponding to the operating channel of UWB communication and the operating frequency band of target communication is greater than 0 but less than the preset frequency. For example, as shown in fig. 7, the frequency band corresponding to the UWB operation channel is 4441.2-4940.4 MHz, the wifi operation frequency band is 4935-4945 MHz, and at this time, there is an overlap portion between the two at 4935-4940.4 MHz, and the interval frequency between the two is 0, so that there is adjacent channel interference between the two; for another example, as shown in fig. 8, the frequency band corresponding to the UWB operation channel is 4441.2 to 4940.4MHz, and the wifi communication operation frequency band is 4943 to 4953MHz, the frequency between the two is 2.6Hz, and if the preset frequency is 5Hz, the frequency between the two is less than 5Hz, so that it can be determined that the adjacent channel interference exists between the UWB communication and the target communication.

In some embodiments, the above manner of determining interference according to the operating frequency band is considered to be determined according to the theoretical condition of interference, and in fact, due to signal strength or the like, too much interference may not be caused. Therefore, the electronic equipment can acquire the signal quality parameters of UWB communication after determining that the frequency multiplication range of target communication is overlapped with the frequency band corresponding to the working channel based on the working frequency band. The signal quality parameters may include received signal strength, packet loss rate, retransmission rate, etc., and the specific signal quality parameters may not be limited. After the signal quality parameters of the UWB communication are obtained, whether the signal quality parameters of the UWB communication meet the first parameter conditions or not can be judged, and if the signal quality parameters of the UWB communication meet the first parameter conditions, harmonic interference between the ultra-wideband communication and the target communication is determined; otherwise, it is determined that no harmonic interference exists between the ultra-wideband communication and the target communication. Wherein, the first parameter condition may be: one or more of the received signal strength being lower than the preset signal strength, the packet loss rate being greater than the preset packet loss rate, and the retransmission rate being greater than the preset retransmission rate, i.e. when the signal quality parameter of UWB communication satisfies the first parameter condition, it indicates that the signal quality of UWB communication is poor, and at this time, harmonic interference exists. That is, in the case where there is coincidence between the frequency multiplication range of the target communication and the frequency band corresponding to the operation channel, harmonic interference is highly likely to exist at this time, and the signal quality parameter of UWB satisfies the first parameter condition, it can be determined that the signal quality parameter of UWB is poor due to the harmonic interference of the target communication to the UWB communication.

Similarly, when determining whether adjacent channel interference exists between the UWB communication and the target communication, the electronic device may acquire a signal quality parameter of the target communication after determining that a frequency of an interval between a frequency band corresponding to a working channel of the UWB communication and a working frequency band of the target communication is smaller than a preset frequency, and determine whether the signal quality parameter of the target communication meets a second parameter condition, and if the second parameter condition is met, determine that adjacent channel interference exists between the UWB communication and the target communication; otherwise, it can be determined that no adjacent channel interference exists between the UWB communication and the target communication. Of course, in this embodiment, after it is determined that the frequency of the interval between the frequency band corresponding to the operating channel of UWB communication and the operating frequency band of target communication is smaller than the preset frequency, the signal quality parameter of UWB communication is obtained, and the signal quality parameter of UWB communication is matched with the set parameter condition, and if the signal quality parameter of UWB communication meets the set parameter condition, it may be determined that adjacent channel interference exists between UWB communication and target communication; otherwise, it can be determined that no adjacent channel interference exists between the UWB communication and the target communication.

Of course, the specific manner in which the electronic device determines whether there is interference between the UWB communication and the target communication may not be limited.

Step S230: and switching the working channel of the ultra-wideband communication based on the frequency band corresponding to the working channel and the working frequency band according to the interference type of the interference in response to the existence of the interference between the ultra-wideband communication and the target communication.

In the embodiment of the application, when the electronic device determines that interference exists between the UWB communication and the target communication, the electronic device may switch the working channel of the ultra wideband communication based on the interference type of the interference, the frequency band corresponding to the working channel, and the working frequency band. If the determined interference is harmonic interference, switching the working channel of the UWB communication to a channel which does not overlap with the frequency multiplication range of the working channel of the target communication according to the frequency band corresponding to the working channel of the current UWB communication and the working frequency band of the target communication; if the determined interference is adjacent frequency interference, switching the working channel of UWB communication to a channel with the interval frequency between the working channel of UWB communication and the working channel of target communication being greater than the preset frequency according to the frequency band corresponding to the working channel of current UWB communication and the working frequency band of target communication.

In some embodiments, if the signal quality parameter is referred to when determining whether there is interference between the UWB communication and the target communication, when switching the working channel of the UWB, the preset forbidden frequency band that cannot be used by the UWB adjustment working frequency band may be defined according to the preset mapping table of the received signal parameter and the communication frequency point. The electronic device may determine frequency points of which the signal quality parameter does not meet the first parameter condition from a preset mapping table, and determine frequency bands corresponding to the frequency points as target frequency bands; when switching channels, the target frequency band can be eliminated, that is, the operating channel of UWB can be switched to a channel corresponding to a frequency band other than the target frequency band, whereby the communication quality of UWB communication can be ensured.

In some embodiments, since UWB communication transmits signals in a wide frequency spectrum, the operating channels of UWB communication include a plurality, that is, when data transmission is completed once, it may transmit data using a plurality of operating channels, and if the number of operating channels after switching is smaller than the number of operating channels before switching, the bandwidth thereof becomes small and the data transmission speed may be affected. Under the condition, the transmitting power of UWB communication can be improved, so that the signal quality of UWB is ensured, the retransmission times of data are reduced, and the efficiency of data transmission is ensured.

According to the communication processing method provided by the embodiment of the invention, under the condition that the electronic equipment enables ultra-wideband communication and target communication simultaneously, whether harmonic interference or adjacent frequency exists or not can be determined according to the channel of the ultra-wideband communication and the working frequency range of the target communication, and under the condition that the interference exists, the working channel of the ultra-wideband communication is switched according to the interference type of the interference, so that the harmonic interference and the adjacent frequency interference between the ultra-wideband communication and the target communication are reduced, the communication performance and the effect of the electronic equipment are improved, and the communication effect of UWB communication is improved.

Referring to fig. 9, fig. 9 is a schematic flow chart of a communication processing method according to another embodiment of the present application. The communication processing method is applied to the electronic device, and will be described in detail with respect to the flow shown in fig. 9, and the communication processing method specifically includes the following steps:

step S310: and under the condition that the electronic equipment starts ultra-wideband communication and target communication, if the electronic equipment performs augmented reality or mixed reality content display, positioning a real object in a real scene through the ultra-wideband communication to acquire a working channel of the ultra-wideband communication and a working frequency band of the target communication.

In the embodiment of the application, when the electronic device enables UWB communication and target communication at the same time, if UWB communication is used for positioning in AR scene or content display of Mixed Reality (MR), UWB is always in a working state, so that communication interference needs to be avoided, and thus positioning accuracy is ensured. Therefore, in the case, the working channel of ultra-wideband communication and the working frequency band of target communication can be obtained, and subsequent steps are executed, so that the positioning accuracy of the electronic equipment in positioning the real object in the real scene is ensured.

Step S320: and determining that interference exists between the ultra-wideband communication and the target communication based on the frequency band corresponding to the working channel and the working frequency band, wherein the frequency bands corresponding to different working channels are different.

Step S330: and switching an operating channel of the ultra-wideband communication in response to interference between the ultra-wideband communication and the target communication.

In the embodiment of the present application, the step S320 and the step S330 may refer to the content of the foregoing embodiment, which is not described herein.

Step S340: and suspending data transmission of the target communication.

In the embodiment of the application, when the electronic device determines that the interference exists between the UWB communication and the target communication, it takes a certain time to switch to the working channel due to the determination of the switching to the working channel, and in the process that the electronic device executes the switching to the working channel of the UWB communication, the electronic device still causes the interference, so that the positioning accuracy of the electronic device for positioning by using UWB is affected. In this case, the electronic device can suspend data transmission of the target communication, thereby avoiding generation of an interference signal to UWB communication. Alternatively, the electronic device may suspend data transmission of uplink communication and data transmission of downlink communication of the target communication at the same time.

In some embodiments, when the electronic device is used for content display in an AR or MR scene, WIFI communication or cellular communication is usually started to acquire resources to be displayed from other devices (such as a server) through WIFI communication or cellular communication, so in the scene, the electronic device generally receives data transmitted by the server, that is, the target communication is generally in a downlink transmission state for a long time, and the uplink transmission situation is relatively less, and the interference to UWB communication is also less. In this case, only the data transmission of the downstream communication of the target communication may be suspended.

Step S350: and when the positioning of the real object in the real scene is completed through the ultra-wideband communication and the pose of the electronic equipment is unchanged, restoring the data transmission of the target communication.

In the embodiment of the application, when the electronic device is used for positioning in an AR or MR scene, the electronic device continuously positions a real scene so as to update display content when the position of the electronic device in the real scene changes; when the electronic equipment is in a certain pose (the pose is not changed) and the positioning of the real object in the real scene is completed, the positioning effect does not influence the display of the content. Therefore, when the positioning of the real object in the real scene is completed through the ultra-wideband communication and the pose of the electronic equipment is unchanged, the data transmission of the target communication is resumed, and therefore, the data transmission of the paused target communication can be resumed in a gap from the completion of the positioning and the pose unchanged to the change of the pose, and the required data transmission is realized in the gap.

In some embodiments, before the electronic device does not complete the switching of the UWB operation channel, but during the process of the electronic device performing the switching of the UWB operation channel, interference to UWB communication is still caused, so that the positioning accuracy of the electronic device for positioning by using UWB is affected. Therefore, under the condition that the determined interference is adjacent frequency interference, the communication frequency range of the target communication can be reduced on the basis of the working frequency band, so that the adjacent frequency interference between the UWB communication and the target communication is reduced.

According to the communication processing method, when the electronic equipment enables ultra-wideband communication and target communication at the same time and the electronic equipment performs positioning in an AR or MR scene through UWB, whether interference exists or not is determined according to the channel of the ultra-wideband communication and the working frequency band of the target communication, and under the condition that the interference exists, the working channel of the ultra-wideband communication is switched to reduce interference between the ultra-wideband communication and the target communication, so that the communication performance and effect of the electronic equipment are improved, and the communication effect of the UWB communication is improved. In addition, under the condition that the interference exists, data transmission of target communication is suspended, so that positioning accuracy in the process of switching the working channel of UWB can be guaranteed, and further content display effect in an AR or MR scene is guaranteed.
