Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

Ultra Wide Band (UWB): the wireless communication method is a novel carrier-free communication technology, and wireless transmission is realized by sending and receiving extremely narrow pulses with the nanosecond or microsecond level or lower, so that the wireless communication method has ultra-large bandwidth and lower transmitting power, and can further realize rapid data transmission on a low power consumption level. Due to the above-mentioned advantages of UWB technology, it is widely used in various scenarios.

Along with the development of urban construction, the density of urban buildings is increased, and the requirements for accurate positioning and navigation in areas with dense buildings are increased. However, the positioning accuracy of the conventional Global Navigation Satellite System (GNSS) Navigation between urban buildings is very poor, the deviation is often several meters or even tens of meters, and especially when a vehicle is ordered in a network, because a passenger is often in the interior of a high building or under the high building, the GNSS positioning often leads a driver of the vehicle to the opposite side of a road or even a nearby street, which brings inconvenience.

Because UWB technology has an extremely high interference rejection capability, and UWB technology can provide millimeter-level accurate location in the room/building/street, etc., by way of TDOA/PDOA. Therefore, in the process of laying a positioning network, a large number of UWB anchor points are usually laid at the basement of the wall to be applied to wireless network access and positioning of UWB terminals in the indoor/building/street and the like.

However, other communication modules, such as a 4G (the 4th generation mobile communication technology) communication module, a 5G (the 5th generation mobile communication technology) communication module, and a WIFI module, are usually present in the electronic device. When the electronic devices simultaneously use the communication modules for communication, interference between networks may exist, thereby affecting the working state of the networks. Also, interference between UWB and other communications is typically harmonic interference and adjacent channel interference.

Harmonic interference is caused when a harmonic of a certain communication system (low-frequency band) falls into a working frequency band of another communication system (high-frequency band), so that the work of the other communication system is influenced, and when the harmonic of A falls into the working frequency band of B, the harmonic of A usually interferes with B, but B does not interfere with A, so that the harmonic interference is generated because the frequency doubling range of the communication frequency bands of other communication is possibly overlapped with the frequency range of UWB; the adjacent channel interference means that the working frequency bands of a certain communication system and another communication system are close, the two communication systems will affect each other when working, and when the working frequency bands of a and B are close, a generally interferes with B, and B also interferes with a.

In the related art, for harmonic interference between UWB and other communications, a filter is usually added to a radio frequency transmission path of other communication modules to suppress interference of its harmonic to the UWB network, for example, as shown in fig. 1, a filter is added to a radio frequency path of Cellular to suppress mutual interference between UWB and Cellular; for adjacent channel interference between UWB and other communications, it is common to increase the antenna isolation between the two (by increasing the spatial distance) to solve mutual interference between adjacent frequency bands of UWB and other communications. However, in these systems, it is necessary to add an additional component or increase the internal space of the electronic device to achieve the effect of reducing the interference, which leads to an increase in cost and an increase in 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 in this embodiment of the present application, which can determine whether there is interference according to a channel of ultra-wideband communication and an operating frequency band of target communication when the electronic device enables the ultra-wideband communication and the target communication at the same time, and reduce the interference between the ultra-wideband communication and the target communication by switching the operating channel of the ultra-wideband communication when there is interference, so as to improve the 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 according to an embodiment of the present disclosure, where 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 to the AP module 11, 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 instruction control to these communication chips. The AP module 11 may be a Central Processing Unit (CPU) or the like; the communication information may include communication states, such as an operating frequency band, signal strength, and the like, which are not limited herein, so that the AP module 11 can acquire the states of the communication chips and can control the communication chips. Of course, other communication chips, such as a bluetooth chip, a zigbee chip, etc., may also be included in the electronic device 100.

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

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

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

In the embodiment of the application, the electronic device may acquire the operating states of the communication modules in real time, so as to reduce mutual interference between UWB communication and target communication that may exist in the electronic device when the UWB communication module and the target communication module are simultaneously turned on, that is, when the UWB communication module and the target communication module are simultaneously enabled. The target communication may be other communication besides the ultra-wideband communication, for example, cellular communication, WIFI communication, bluetooth communication, etc., and the electronic device may determine interference between the UWB communication and other communication; the electronic device may also be configured to perform UWB communication, and optionally include at least two UWB modules, and when the at least two UWB modules are enabled to perform communication, the electronic device may also determine interference between the UWB communications, for example, when the two UWB modules are simultaneously enabled, and channels used by the two UWB modules are the same, interference may exist, and at this time, the interference needs to be avoided and reduced. The method comprises the steps that under the condition that any one of UWB communication and target communication is determined to be started, an electronic device obtains a working channel of the UWB communication and a working frequency range of the target communication, so that whether interference exists between the UWB communication and the target communication is determined; that is, as long as the electronic device enables at least two types of communication simultaneously, and the at least two types of communication include UWB communication, an operating channel of the UWB communication and an operating frequency band of the target communication may be acquired. It can be understood that, generally, UWB communication has a plurality of operating channels, and frequency ranges of different operating channels are different, and other communications also operate in corresponding frequency bands when operating, so that there exists a frequency range corresponding to the operating channel of UWB communication, and when a corresponding condition is satisfied between the operating frequency bands of target communications, interference may exist between the UWB communication and the target communications, and thus, the interference that may occur in the electronic device may be determined.

In some embodiments, the electronic device may enable UWB communication and target communication simultaneously in multiple scenes, for example, when the electronic device is used in an Augmented Reality (AR) scene, the electronic device may simultaneously start UWB communication and WIFI communication, so that positioning of a real scene may be performed through UWB communication, and AR resource content may be acquired through WIFI communication; for another example, when the electronic device is used for playing music through a connected bluetooth headset and the electronic device is used in 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 enables UWB communication and object communication at the same time 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 from the communication module corresponding to the target communication. Of course, the electronic device may also control the operating system to enter a setting mode, so as to obtain a working channel of UWB communication and a working frequency band of target communication in a working state, where the setting mode may be an engineering mode corresponding to the operating system, and the like, and 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 application, after acquiring the working channel of the UWB communication and the working frequency band of the target communication, the electronic device may determine whether there is interference between the ultra-wideband communication and the target communication based on the frequency band (frequency range) and the working frequency band corresponding to the acquired working channel, so as to perform corresponding processing when it is determined that there is interference between the ultra-wideband communication and the target communication, thereby reducing interference between the UWB communication and the target communication.

In some embodiments, the electronic device may determine whether the frequency band corresponding to the operating channel and the operating frequency band of the target communication satisfy the interference condition of any interference type according to different interference types. It is understood that the interference conditions corresponding to different interference types are different, and whether any type of interference exists between the UWB communication and the target communication may 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 target communication is multiple, that is, when the electronic device enables multiple communications in addition to the UWB communication, the processes of step S110 and step S120 may be performed for each of the target communications, so as to determine whether or not interference exists between the UWB communication and each of the target communications, and perform a corresponding process based on the determination result.

Step S130: 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, in the case that it is determined that interference exists between the UWB communication and the target communication, the electronic device may switch the operating channel of the UWB communication in order to reduce the interference existing between the UWB communication and the target communication. 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 type of the existing interference, so that the interference between the UWB communication and the target communication does not exist theoretically, and the possibility of the interference between the UWB communication and the target communication is reduced.

In some embodiments, a mapping table corresponding to different interference types may be stored in the electronic device, where in the mapping table, an optional working channel for UWB communication in each possible working frequency band of the target communication is stored, and the optional working channel can ensure that there is no communication interference of the interference type between the UWB communication and the target communication. The electronic device may switch an operating channel of the UWB communication to an optional operating channel based on the mapping table. For example, as shown in the following table, which shows a mapping table corresponding to harmonic interference,

of course, this table is only an exemplary illustration of the mapping table corresponding to harmonic interference.

In other embodiments, when responding to interference between UWB communication and target communication, the electronic device may determine, for each of the other operating channels of the UWB communication, whether there is interference between the operating channel and the target communication in turn, that is, determine whether there is interference based on a frequency band corresponding to each of the other operating channels and an operating frequency band of the target communication in turn, thereby determining a channel without interference and using the channel as an operating channel to be switched to. Wherein, the other working channels are working channels except the current working channel in the communication channel of the UWB communication. Of course, the specific manner of switching the working channel of the UWB communication may not be limited in response to the interference between the UWB communication and the target communication, and it is only necessary that the interference does not exist between the UWB communication and the target communication after the channel of the UWB communication is adjusted.

In some embodiments, the target communication enabled by the electronic device may include multiple communications, and in this case, when the electronic device switches the operating channel of the UWB communication, the electronic device may determine, according to the operating frequency band of each communication in the target communication, a channel corresponding to a frequency band in which interference does not exist in each communication, and switch the operating channel of the UWB communication to the determined operating channel, thereby theoretically avoiding interference between the UWB communication and the target communication.

In one possible implementation, in some cases, it may not be possible to determine the channels corresponding to the frequency bands where there is no interference for each communication. At this time, in order to smoothly determine the working channel that can be adjusted to, 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 there is no interference in each communication is determined. For example, when the target communication includes cellular communication and WIFI communication, a frequency band corresponding to an operating channel of the UWB is 4441.2-4940.4MHz, an operating frequency band of the WIFI communication is 4920-4930MHz, and an operating frequency band of the cellular communication is 2320-2370MHz, at this time, adjacent frequency interference exists between the UWB communication and the WIFI communication, and harmonic interference exists between the UWB communication and the cellular communication, so that interference does not exist between the UWB communication and the WIFI communication and between the cellular communication at the same time. Under the condition, no selectable channel may exist in the communication channel of the UWB, so that interference does not exist between the UWB communication and the WIFI communication and between the UWB communication and the cellular communication at the same time, and under such a condition, the operating frequency band of the WIFI communication may be changed by the electronic device to be one of the 5GHz frequency bands (5925 and 7125MHz), and at this time, the channel 9(7489.6-8489.6MHz) may be found, so that the adjacent frequency interference between the UWB communication and the WIFI communication may be avoided while the harmonic interference between the UWB communication and the cellular communication may be effectively avoided. Alternatively, if the target communication includes communication in which the operating frequency cannot be directly changed, the operating frequency may also be changed in a manner that the electronic device requests resources, so that the electronic device can switch the UWB operating channel to an appropriate 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.

The communication processing method provided by the embodiment of the application can determine whether interference exists according to the channel of the ultra-wideband communication and the working frequency bands of other communications under the condition that the electronic equipment simultaneously starts the ultra-wideband communication and the target communication, and reduce the interference between the ultra-wideband communication and the target communication by switching the working channel of the ultra-wideband communication under the condition that the interference exists, so that the communication performance and effect of the electronic equipment are improved, and the communication effect of the ultra-wideband communication is improved.

Referring to fig. 4, fig. 4 is a flowchart 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 may specifically include the following steps:

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

In the embodiment of the present application, step S210 may refer to the contents of other embodiments, which are not described herein again.

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, interference between the ultra-wideband communication and target communication mainly includes harmonic interference and adjacent channel interference, and when determining the interference between the ultra-wideband communication and the target communication, the electronic device may determine whether harmonic interference or adjacent channel interference exists between the ultra-wideband communication and the target communication based on a frequency band corresponding to a working channel of the ultra-wideband communication and a working frequency band of the target communication, so as to process communication of the electronic device when determining that the harmonic interference or the adjacent channel interference exists between the ultra-wideband communication and the target communication. The electronic device may determine whether harmonic interference exists between the ultra-wideband communication and the target communication based on the condition of the harmonic interference, and determine whether adjacent channel interference exists between the ultra-wideband communication and the target communication based on the condition of the adjacent channel interference.

In some embodiments, referring to fig. 5, the 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 working channel and the working frequency band may include:

step S221: and if the frequency doubling 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, determining that 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 the UWB communication is high, it is general that the harmonics of the target communication fall within the frequency band of the UWB communication, causing harmonic interference to the UWB communication. Therefore, the electronic device may determine whether the frequency multiplication range of the target communication coincides with the frequency band corresponding to the operating channel to determine whether the target communication generates harmonic interference on the UWB communication.

Optionally, the electronic device may obtain, based on the operating frequency band, a frequency doubling range of uplink communication or a frequency doubling range of downlink communication of the target communication, as the first frequency range; acquiring a frequency range of downlink communication corresponding to the working channel as a second frequency range; and if the first frequency range is overlapped with the second frequency range, determining that harmonic interference exists between the ultra-wideband communication and the target communication. It can be understood that, in general, the frequency range of the uplink communication of the communication is the same as the frequency range of the downlink communication, and therefore, 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, the cause of the generation of the harmonic interference is generally that the operating frequency range of one communication falls within the downstream frequency range of another communication, and therefore, the frequency range of the downstream communication of the 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, if so, indicating that harmonic interference exists between the target communication and the UWB communication, and if not, indicating that harmonic interference does not exist between the target communication and the UWB communication. For example, as shown in fig. 6, the frequency range of the UWB downlink communication is 5989.6-6989.6 MHz; the target communication is cellular communication, the frequency range is 3300-3400 MHz, the frequency multiplication range is 6600-6800 MHz, and the frequency range of 5989.6-6989.6 MHz includes the frequency range of 6600-6800 MHz, so that the harmonic interference of the current cellular communication to the UWB communication can be determined.

Step S222: and if the frequency of 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 channel interference exists between the ultra-wideband communication and the target communication.

In this embodiment, the electronic device may acquire a frequency spaced between a frequency band corresponding to UWB communication and an operating frequency band of target communication. For example, the working frequency band of the target communication is 5925-7125MHz, the frequency band corresponding to the working channel of the UWB communication is 5989.6-6989.6 MHz, and at the moment, the frequency band of 5925-7125MHz comprises 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 working channel is 4441.2-4940.4MHz, the working frequency band of the WIFI communication is 4943-4953MHz, and the separation frequency between the two is: 4943-4940.4 at 2.6 Hz. After acquiring the spaced frequency between the frequency band corresponding to the UWB communication and the working frequency band of the target communication, the electronic device may compare the spaced frequency with a preset frequency, and if the spaced frequency is smaller than the preset frequency, it indicates that adjacent frequency interference exists between the UWB communication and the target communication; otherwise, if the frequency of the interval is not less than the preset frequency, it indicates that there is no adjacent channel interference between the UWB communication and the target communication. The specific value of the preset frequency may not be limited, and may be, for example, 2Hz, 5Hz, 10Hz, and the like.

It can be understood that the above spaced frequency is less than the preset frequency, and includes two cases, one case is that there is an overlap between the frequency band corresponding to the working channel of UWB communication and the working frequency band of target communication, that is, the spaced frequency is 0; in another case, the frequency of the interval between the frequency band corresponding to the working channel of the UWB communication and the working frequency band of the target communication is greater than 0 but less than the preset frequency. For example, as shown in fig. 7, a frequency band corresponding to a working channel of the UWB is 4441.2-4940.4MHz, a working frequency band of the WIFI communication is 4935-4945 MHz, an overlapping portion between the two is 4935-4940.4 MHz, and an interval frequency between the two is 0, so that adjacent frequency interference exists between the two; for another example, as shown in fig. 8, the frequency band corresponding to the UWB working channel is 4441.2-4940.4MHz, the working frequency band of the WIFI communication is 4943-4953MHz, 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 adjacent frequency interference exists between the UWB communication and the target communication.

In some embodiments, the above method for determining interference according to the operating frequency band is determined according to the theoretical condition of interference, and actually, the method may not cause too much interference due to the signal strength and the like. Therefore, the electronic device can also acquire the signal quality parameters of the UWB communication after determining that the frequency doubling range of the target communication coincides with the frequency band corresponding to the working channel based on the working frequency band. The signal quality parameter may include received signal strength, packet loss rate, retransmission rate, and the like, and the specific signal quality parameter 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 a first parameter condition or not can be judged, and if the signal quality parameters meet the first parameter condition, harmonic interference between the UWB communication and target communication is determined; and otherwise, determining that harmonic interference does not exist between the ultra-wideband communication and the target communication. Wherein, the first parameter condition may be: when the received signal strength is lower than one or more of the preset signal strength, the packet loss rate is greater than the preset packet loss rate, and the retransmission rate is greater than the preset retransmission rate, that is, when the signal quality parameter of the UWB communication meets the first parameter condition, it indicates that the signal quality of the UWB communication is poor, and at this time, harmonic interference exists. That is to say, under the condition that the frequency doubling range of the target communication is overlapped with the frequency band corresponding to the working channel, harmonic interference may exist greatly at this time, and the signal quality parameter of the UWB satisfies the first parameter condition, it may be determined that the poor signal quality parameter of the UWB is caused by 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, after determining that the frequency of the interval between the frequency band corresponding to the working channel of the UWB communication and the working frequency band of the target communication is less than the preset frequency, the electronic device may acquire the signal quality parameter of the target communication, and determine whether the signal quality parameter of the target communication satisfies a second parameter condition, and if the second parameter condition is satisfied, may 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 determining that the frequency of the interval between the frequency band corresponding to the operating channel of the UWB communication and the operating frequency band of the target communication is less than the preset frequency, acquiring a signal quality parameter of the UWB communication, and matching the signal quality parameter of the UWB communication with the set parameter condition, if the signal quality parameter of the UWB communication satisfies the set parameter condition, it may be determined 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, the specific manner in which the electronic device determines whether interference exists between the UWB communication and the target communication may not be limiting.

Step S230: and responding to the interference between the ultra-wideband communication and the target communication, and switching 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.

In the embodiment of the present application, when determining that there is interference 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 coincide with the frequency doubling 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, the working channel of the UWB communication needs to be switched to a channel, in which the frequency interval between the working channels of the UWB communication and the target communication is greater than the preset frequency, according to the frequency band corresponding to the working channel of the current UWB communication and the working frequency band of the target communication.

In some embodiments, if it is determined whether there is interference between the UWB communication and the target communication, the signal quality parameter is referred to, and when the working channel of the UWB is switched, the UWB adjustment working frequency band may be further limited to not use the preset forbidden frequency band according to a preset mapping table of the received signal parameter and the communication frequency point. The electronic equipment can determine frequency points with signal quality parameters which do 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 the channel is switched, the target frequency band can be excluded, that is, the working channel of the UWB is switched to a channel corresponding to a frequency band other than the target frequency band, so that the communication quality of the UWB communication can be ensured.

In some embodiments, because UWB communication transmits signals in a wide frequency spectrum range, the working channels of UWB communication include a plurality of working channels, that is, when one data transmission is completed, it may transmit data by using a plurality of working channels, and if the number of working channels after switching is smaller than the number of working channels before switching after switching the working channels of UWB, the bandwidth of the working channels becomes smaller, and the data transmission speed is 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.

The communication processing method provided by the embodiment of the application can determine whether harmonic interference or adjacent frequency exists according to the channel of the ultra-wideband communication and the working frequency band of the target communication under the condition that the electronic equipment simultaneously starts the ultra-wideband communication and the target communication, and switch the working channel of the ultra-wideband communication according to the interference type of the interference under the condition that the interference exists, 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 effect of the electronic equipment are improved, and the communication effect of the ultra-wideband communication is improved.

Referring to fig. 9, fig. 9 is a flowchart 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. 9, and the communication processing method may specifically include the following steps:

step S310: under the condition that the electronic equipment starts ultra-wideband communication and target communication, if the electronic equipment displays augmented reality or mixed reality contents, the real object in a real scene is positioned through the ultra-wideband communication, and a working channel of the ultra-wideband communication and a working frequency band of the target communication are obtained.

In the embodiment of the application, when the electronic device simultaneously enables UWB communication and target communication, if the UWB communication is used for positioning in displaying content of an AR scene or a Mixed Reality (MR), the UWB is always in a working state, and therefore communication interference needs to be avoided, thereby ensuring positioning accuracy. Therefore, under the condition, the working channel of the ultra-wideband communication and the working frequency band of the target communication can be obtained, and the subsequent steps are executed, so that the positioning accuracy of the electronic equipment in the positioning of 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: 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, step S320 and step S330 may refer to the contents of the foregoing embodiments, and are not described herein again.

Step S340: suspending data transmission of the target communication.

In the embodiment of the present application, when the electronic device determines that there is interference between UWB communication and target communication, and switches the working channel of UWB communication, because it takes a certain time to determine the working channel to which to switch and to switch, interference may still be caused in the process of switching the working channel of UWB communication performed by the electronic device, thereby affecting the positioning accuracy of the electronic device for positioning by using UWB. In this case, the electronic device may suspend data transmission of the target communication, thereby avoiding generation of an interference signal to the UWB communication. Optionally, the electronic device may suspend the data transmission of the upstream communication and the data transmission of the downstream 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, the WIFI communication or the cellular communication is usually turned on to obtain resources to be displayed from other devices (e.g., a server, etc.) through the WIFI communication or the cellular communication, and therefore in this scene, the electronic device usually receives data transmitted by the server, that is, the target communication is usually in a downlink transmission state for a long time, while the uplink transmission is relatively less, and 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 not changed, recovering 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, a real scene is continuously positioned, so that when the position of the electronic device in the real scene changes, the display content is updated; 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 affect the display of the content at the moment. Therefore, when the positioning of the real object in the real scene by the ultra-wideband communication is completed and the pose of the electronic device is not changed, the data transmission of the target communication is resumed, and thus, the data transmission of the suspended target communication can be resumed in the gap from the completion of the positioning and the change of the pose to the change of the pose, thereby realizing the required data transmission in the gap.

In some embodiments, before the electronic device does not complete the switching of the operating channel of the UWB, interference to the UWB communication is still caused in the process of switching the operating channel of the UWB communication performed by the electronic device, thereby affecting the positioning accuracy of the electronic device for positioning by the UWB. Therefore, when the determined interference is adjacent channel interference, the communication frequency range of the target communication can be narrowed on the basis of the working frequency band, so as to reduce the adjacent channel interference between the UWB communication and the target communication.

According to the communication processing method provided by the embodiment of the application, the ultra-wideband communication and the target communication can be simultaneously started in the electronic equipment, when the electronic equipment is positioned in an AR or MR scene through the 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, so that the interference between the ultra-wideband communication and the target communication is reduced, 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, the data transmission of the target communication is suspended, so that the positioning precision in the process of switching the UWB working channel can be ensured, and the content display effect in an AR or MR scene is further ensured.
