Technical Field

The present application relates to the field of communication technology, and in particular to a communication method, medium and electronic equipment.

Background Art

Electronic devices such as mobile phones and tablets usually support multiple wireless communication technologies, such as supporting wireless local area networks (Wi-Fi) and cellular networks at the same time. In some usage scenarios, electronic devices may use two communication modules to access Wi-Fi networks and cellular networks at the same time, such as Wi-Fi Internet access and cellular network calls, Wi-Fi hotspot sharing and cellular network data services, distributed communications, multi-network collaboration and other application scenarios. These two communication modules are used simultaneously. Among them, when the two communication modules of the electronic device work at the same time, adjacent frequency interference or harmonic interference may occur, greatly reducing the communication quality of the electronic device. For example, the second harmonic of the Wi-Fi 2.4G frequency band is around 4.8GHz to 4.96GHz, which will directly fall within the frequency band range of the 5G cellular network N79, and will cause harmonic interference that seriously affects the communication quality of the two systems. For example, the Wi-Fi 2.4G frequency band is adjacent to the 2.5G to 2.6G frequency band range of the cellular network N41, which will cause adjacent frequency interference that affects the communication quality of the two systems.

Summary of the invention

The embodiments of the present application provide a communication method, a medium, and an electronic device, which can comprehensively consider factors such as the actual received signal strength value of the antenna and the isolation of the antenna. When there are two wireless communication modules of the same type working in the electronic device, one of the antennas with higher antenna isolation and stronger received signal strength is scheduled, thereby optimizing coexistence interference.

In the first aspect, the present application provides a communication method, which is applied to an electronic device, wherein the electronic device includes a first communication module and a second communication module, wherein the first communication module includes a plurality of first antennas, and the second communication module includes at least one second antenna; the method includes: corresponding to the first working frequency band of the first communication module and the second working frequency band of the second communication module satisfying the interference condition, obtaining a plurality of first strength attenuation values corresponding to the plurality of first antennas of the first communication module, wherein the plurality of first antennas correspond to the plurality of first strength attenuation values one by one; and adjusting the received signal strength values of the corresponding first antennas according to the plurality of first strength attenuation values, wherein the higher the antenna isolation between the first antenna and the second antenna, the smaller the first strength attenuation value of the first antenna. It can be understood that the first working frequency band of the first communication module and the second working frequency band of the second communication module satisfy the interference condition, indicating that there is coexistence interference between the communication of the first communication module and the communication of the second module, for example, there is coexistence interference between the transmission of the first communication module and the reception of the second communication module. Moreover, the first strength attenuation value corresponding to each first antenna is used to reduce the corresponding received signal strength value, and the greater the first strength attenuation value corresponding to the first antenna, the greater the degree of reduction of the corresponding received signal value. In this way, during the operation of the first wireless communication module, the received signal strength of the antenna with lower antenna isolation decreases to a greater extent. The greater the decrease in the received signal strength of the antenna, the smaller the received signal strength value of the antenna. Furthermore, the antenna with lower isolation is usually not scheduled during the operation of the first communication module, which can reduce the coexistence interference with the second communication module. In addition, the above-mentioned first communication module can also be referred to as a first wireless communication module, and the above-mentioned second communication module can also be referred to as a second wireless communication module.

In a possible implementation, the above-mentioned adjusting the received signal strength values of the corresponding first antennas respectively according to the multiple first strength attenuation values includes: according to the multiple first strength attenuation values, subtracting the corresponding first strength attenuation value from the received signal strength value of each first antenna to obtain the adjusted received signal strength value of each first antenna. In this way, after the received signal strength of the antenna with lower antenna isolation is subtracted from the corresponding strength attenuation value, the degree of reduction of the received signal strength of the antenna will be greater than the degree of reduction of the received signal strength of the antenna with higher isolation. The greater the degree of reduction of the received signal strength of the antenna, the smaller the received signal strength value of the antenna, so as to achieve the purpose of finally scheduling the antenna with higher antenna isolation in the first communication module.

In a possible implementation, the method further includes: scheduling the multiple first antennas according to the adjusted received signal strength values of the multiple first antennas. In this way, the adjusted received signal strength of the antenna with higher antenna isolation in the first communication module in the application is generally larger, so as to achieve scheduling of the antenna with higher antenna isolation in the first communication module.

In a possible implementation, the above-mentioned scheduling of multiple first antennas according to the adjusted received signal strength values of the multiple first antennas includes: scheduling a transmitting antenna from the multiple first antennas to perform uplink data transmission according to the adjusted received signal strength values of the multiple first antennas. The uplink data of the first communication module will cause coexistence interference to the downlink data received by the second communication module.

In one possible implementation, the above-mentioned interference conditions include that the first working frequency band and the second working frequency band are two frequency bands in the target coexistence frequency band, wherein the two frequency bands in the target coexistence frequency band satisfy at least one of the following conditions: the difference between the maximum value of the range of the first working frequency band and the minimum value of the range of the second working frequency band is less than or equal to the preset difference, that is, the first working frequency band and the second working frequency band are adjacent or close, and there is adjacent frequency interference between the two working frequency bands; the difference between the integer multiple of the maximum value of the range of the first working frequency band and the minimum value of the range of the second working frequency band is less than or equal to the preset difference, that is, the harmonic of the first working frequency band is adjacent or close to the second working frequency band, and there is harmonic interference between the two working frequency bands.

In a possible implementation, the target coexistence frequency band is one of a plurality of pre-set coexistence frequency bands, and the first intensity attenuation values corresponding to the coexistence frequency bands of the same type are the same, and the first intensity attenuation values corresponding to the coexistence frequency bands of different types are different. For example, the target coexistence frequency band may include the 2.4G frequency band of Wi-Fi and the N41 frequency band of the cellular network.

In a possible implementation, in the above-mentioned same type of coexistence frequency band, the antenna of the first communication module and the antenna in the second communication module remain unchanged. Then, in different coexistence frequency bands of the same type, the antenna isolation between each first antenna and each second antenna remains unchanged. In this way, for different coexistence frequency bands in the same type of coexistence frequency band, the first strength attenuation value configured for each first antenna in the first communication module is the same, thereby realizing antenna scheduling from the same multiple first antennas.

In a possible implementation, at least one second antenna in the second communication module is a plurality of second antennas; the method further includes: corresponding to the first working frequency band of the first communication module and the second working frequency band of the second communication module satisfying the interference condition, obtaining a plurality of second strength attenuation values corresponding to the plurality of second antennas of the second communication module, wherein the plurality of second antennas correspond one to one with the plurality of second strength attenuation values; adjusting the received signal strength values of the corresponding second antennas respectively according to the plurality of second strength attenuation values, wherein the higher the antenna isolation between the second antenna and the first antenna, the smaller the second strength attenuation value of the second antenna. Moreover, the second strength attenuation value corresponding to each second antenna is used to reduce the corresponding received signal strength value, and the greater the second strength attenuation value corresponding to the second antenna, the greater the degree of reduction of the corresponding received signal value. In this way, the second antenna with high antenna isolation has a larger received signal strength after adjustment, which is conducive to scheduling the operation of the second antenna with high antenna isolation in the second communication module.

In a possible implementation, the above-mentioned adjusting the corresponding received signal strength values of each second antenna according to multiple second strength attenuation values includes: according to the multiple second strength attenuation values, subtracting the corresponding second strength attenuation value from the received signal strength value of each second antenna to obtain the adjusted received signal strength value of each second antenna. In this way, after the received signal strength of the antenna with lower antenna isolation is subtracted from the corresponding strength attenuation value, the degree of reduction of the received signal strength of the antenna will be greater than the degree of reduction of the received signal strength of the antenna with higher isolation. The greater the degree of reduction of the received signal strength of the antenna, the smaller the received signal strength value of the antenna, so as to achieve the purpose of finally scheduling the antenna with higher antenna isolation in the second communication module.

In a possible implementation, the method further includes: scheduling multiple second antennas according to the adjusted received signal strength values of the multiple second antennas. In this way, the adjusted received signal strength of the antenna with higher antenna isolation in the second communication module in the application is generally larger, so as to achieve scheduling of the antenna with higher antenna isolation in the second communication module. Furthermore, the first communication module and the second communication module both schedule the antenna with higher antenna isolation, which can greatly optimize the coexistence interference between the two modules.

In a possible implementation, the above-mentioned scheduling of multiple second antennas according to the adjusted received signal strength values of the multiple second antennas includes: scheduling receiving antennas from the multiple second antennas for downlink data transmission according to the adjusted received signal strength values of the multiple second antennas. Then, when the first antenna with high antenna isolation in the first communication module is scheduled to send uplink data, and the second antenna with high antenna isolation is scheduled from the multiple second antennas for downlink data transmission, the less interference is generated to the downlink data received by the second communication module, so that the downlink communication quality of the second communication module is higher.

In one possible implementation, the multiple second strength attenuation values corresponding to the same type of coexistence frequency bands are the same, and the multiple second strength attenuation values corresponding to the different types of coexistence frequency bands are different. Then, in different coexistence frequency bands of the same type, the antenna isolation between each first antenna and each second antenna is unchanged. In this way, for different coexistence frequency bands in the same type of coexistence frequency band, the second strength attenuation value configured for each second antenna in the second communication module is the same, thereby realizing antenna scheduling from the same multiple second antennas.

Interference condition judgment and adjustment of the received signal strength value of each antenna are performed only when the conditions are met, which improves the execution efficiency of the antenna scheduling process.

In a possible implementation, the method further includes: determining that the state of at least one of the first communication module and the second communication module has changed; and obtaining a first operating frequency band of the first communication module and a second operating frequency band of the second communication module. In this way, it is possible to determine in real time whether there is interference between the two communication modules and which coexisting frequency bands cause interference, thereby improving the flexibility of antenna scheduling and communication.

In a possible implementation, the method further includes: corresponding to the working frequency band of the first communication module and the second working frequency band of the second communication module not satisfying the interference condition, obtaining multiple first default strength attenuation values corresponding to each first antenna of the first communication module, and the multiple first default strength attenuation values are the same; according to the multiple first default strength attenuation values, respectively adjusting the received signal strength values of the corresponding first antennas; and scheduling the multiple first antennas according to the adjusted received signal strength values of the multiple first antennas. For example, each default strength attenuation value is 0dB.

In a possible implementation, the method further includes: corresponding to the working frequency band of the first communication module and the second working frequency band of the second communication module not satisfying the interference condition, obtaining multiple second default strength attenuation values corresponding to each second antenna of the first communication module, and the multiple second default strength attenuation values are the same; adjusting the corresponding received signal strength values of each second antenna according to the multiple second default strength attenuation values; scheduling the multiple second antennas according to the adjusted received signal strength values of the multiple second antennas. In this way, for the scenarios where there is coexistence interference and there is no coexistence interference between the two modules, the processing logic in the antenna scheduling process is consistent, and the same code can be reused in actual applications, thereby improving the execution efficiency of the antenna scheduling process.

In a second aspect, the present application provides a readable medium having instructions stored thereon, which, when executed on an electronic device, causes the electronic device to execute a communication method as in the first aspect and any possible implementation thereof.

In a third aspect, the present application provides an electronic device, comprising: a memory for storing instructions executed by one or more processors of the electronic device, and a processor, which is one of the processors of the electronic device, for executing the communication method as in the first aspect and any possible implementation thereof.

DETAILED DESCRIPTION

Illustrative embodiments of the present application include, but are not limited to, communication methods, media, and electronic devices.

As can be seen from the background technology, when an electronic device uses two wireless communication modules to work at the same time, coexistence interferences such as harmonic interference and adjacent frequency interference may be generated, and these coexistence interferences will seriously affect the communication quality and performance of the two communication modules in the electronic device. Among them, adjacent frequency interference refers to the mutual interference between signals of adjacent or close channels, and sometimes adjacent frequency is also called adjacent frequency. Harmonic wave interference refers to the interference of harmonics generated in the power grid or circuit to the power grid or the electrical equipment in the power grid. Harmonic is the electrical quantity whose frequency contained in the current is an integer multiple of the fundamental wave.

In order to solve the coexistence interference, a conventional technology is to use time division to allocate different time slots to the two communication modules in the electronic device through a central controller to avoid one module transmitting while the other module is receiving. In this way, the two communication modules are prevented from working at the same time to avoid the coexistence interference. However, the time division of the two communication modules will reduce the throughput and increase the delay.

Another conventional technology uses frequency division to allocate frequencies to the two communication modules of the electronic device through a central controller to avoid coexistence interference such as adjacent frequency interference or harmonic interference between the two modules. However, electronic devices generally cannot determine their own operating frequencies, and the frequencies will follow access points such as base stations or routers, making this solution difficult to implement.

Another conventional technology can use the method of backing off the transmission power, and the transmission power of the two communication modules can be reduced through the central controller to reduce the degree to which the transmission of one module interferes with the reception of the other module. Although there is no delay in the transmission and reception in this solution, the uplink communication of the electronic device is restricted, which will reduce the communication quality of the two communication modules, reduce the module performance, and the benefits are small.

It can be understood that adjacent channel interference and harmonic interference depend largely on the antenna isolation of different communication modules in electronic devices, that is, the communication quality of antennas in different communication modules is related to antenna isolation. Antenna isolation refers to the ratio of the signal power transmitted by one antenna to the signal power received by another antenna. The higher the antenna isolation, the higher the communication quality of the antenna. Antenna isolation is usually the antenna isolation between the antenna in one communication module and the antenna in another communication module in the same device.

Therefore, in order to solve the above problems, an embodiment of the present application provides a communication method. In this method, when an electronic device uses two wireless communication modules to work at the same time, if it is detected that the two wireless communication modules have similar or adjacent working frequency bands, or the frequency band of the harmonics generated by one wireless communication module is adjacent or close to the working frequency band of another wireless communication module, then during the communication process, the antenna with poor antenna isolation in one of the wireless communication modules is usually not scheduled. Furthermore, the antenna with low isolation is not scheduled during the operation of the wireless communication module, which can avoid the situation where the communication of the module using the antenna with low isolation is seriously interfered by another wireless communication module. Correspondingly, the antenna with high isolation is usually scheduled during the operation of the wireless communication module, thereby reducing the coexistence interference such as harmonic interference or adjacent frequency interference caused by the communication of another wireless communication module to the communication of the wireless communication module, that is, improving the communication quality of the wireless communication module.

In some embodiments, the method for avoiding scheduling an antenna with poor antenna isolation in one of the wireless communication modules can be: first, according to the antenna isolation of multiple antennas in one of the wireless communication modules of the electronic device, a strength attenuation value is set for each antenna, wherein an antenna with low antenna isolation has a higher strength attenuation value. Moreover, during the operation of the wireless communication module, after subtracting the corresponding strength attenuation value from the received signal strength of the antenna with low antenna isolation, the degree of reduction of the received signal strength of the antenna will be greater than the degree of reduction of the received signal strength of the antenna with high isolation. The greater the degree of reduction of the received signal strength of the antenna, the smaller the received signal strength value of the antenna. Furthermore, the antenna with low isolation is not scheduled during the operation of the wireless communication module in which it is located, which can reduce the coexistence interference with another wireless communication module.

In this way, the present application can comprehensively consider factors such as the actual received signal strength value of the antenna and the isolation of the antenna. When there are two wireless communication modules of the same type working in an electronic device, one of the antennas with higher antenna isolation and stronger received signal strength can be scheduled, thereby optimizing coexistence interference.

In some embodiments, the present application may pre-set multiple coexistence frequency bands. Each coexistence frequency band includes two frequency bands with interference, and the coexistence frequency bands in the present application may also be referred to as coexistence parameters. Specifically, one frequency band in some coexistence frequency bands is close to or adjacent to the range of another frequency band, that is, there is adjacent frequency interference between the two frequency bands in these coexistence frequency bands. The harmonics of one frequency band in other coexistence frequency bands are close to or adjacent to the range of another frequency band, that is, there is adjacent frequency interference between the two frequency bands in these coexistence frequency bands.

It can be understood that the method of detecting that two wireless communication modules have adjacent or similar working frequency bands, or that the frequency band of harmonics generated by one wireless communication module is close to or adjacent to the working frequency band of another wireless communication module includes: determining whether the respective working frequency bands of the two wireless communication modules fall within a pre-set coexistence frequency band at the same time, that is, whether the respective working frequency bands of the two wireless communication modules are two frequency bands in the coexistence frequency band respectively.

In some implementations, for different coexisting frequency bands, the present application sets different strength attenuation values for multiple antennas in one wireless communication module of the electronic device. The strength attenuation value of each antenna can also be called a weight, which is not specifically limited in the present application.

In some other embodiments, while setting multiple strength attenuation values for each coexistence frequency band for multiple antennas in a wireless communication module in an electronic device, multiple corresponding strength attenuation values can also be set for each coexistence frequency band for multiple antennas in another wireless communication module in the electronic device. Furthermore, for the same coexistence frequency band, multiple strength attenuation values corresponding to one wireless communication module in the electronic device can be used to adjust the received signal strength of the corresponding multiple antennas respectively, and multiple strength attenuation values corresponding to another wireless communication module can be used to adjust the received signal strength of the corresponding multiple antennas respectively.

In this way, the present application can adopt a space division method, without affecting the antenna configuration in the two wireless communication modules in the electronic device, by selecting an antenna with better antenna isolation in space to work, avoiding the use of antennas that generate strong interference, thereby improving the communication quality of the wireless communication module. In addition, the problems existing in the above-mentioned conventional technical means are avoided.

In some embodiments, electronic devices suitable for the present application may be various electronic devices with multiple communication modules, such as: mobile phones, computers, laptop computers, tablet computers, televisions, display devices, outdoor display screens, vehicle-mounted terminals and other devices.

In one embodiment, the communication method provided by the present application can be applied to a scenario where two or more wireless communication modules in an electronic device work simultaneously and there is coexistence interference. Each wireless communication module can be, for example, a Wi-Fi communication module, a cellular network communication module, and a Bluetooth communication module, but is not limited thereto.

In some embodiments, each wireless communication module can realize the transmission and reception functions through an antenna system, wherein the antenna system is composed of a transmitting antenna and a receiving antenna, wherein the transmitting antenna can be called a TX antenna and the receiving antenna can be called an RX antenna, where RX stands for receive and TX stands for transmit.

It is understood that each wireless communication module may include one or more antennas. For example, in electronic devices, especially high-end devices, both the Wi-Fi module and the cellular network module may include multiple antennas. In addition, the Bluetooth communication module may include one antenna.

1 , a schematic diagram of a system architecture for an application of a communication method is provided in the present application. The system architecture includes an electronic device 100 , a network node 200 , and a network node 300 .

The electronic device 100 can communicate with the network node 200 and the network node 300 respectively. For example, when the electronic device 100 includes the wireless communication module 1 and the wireless communication module 2, the electronic device 100 can simultaneously use the wireless communication module 1 to communicate with the network node 200, and use the wireless communication module 2 to communicate with the network node 300.

It can be understood that the wireless communication module 1 and the wireless communication module 2 in the electronic device 100 may include at least one of the following: a cellular network module, a Wi-Fi module, and a Bluetooth module.

In some embodiments, the network node 200 and the network node 300 may be devices such as base stations, routers, gateways, access sites, etc., but are not limited thereto. For example, the wireless communication module 1 is a cellular network module and the wireless communication module 2 is a Wi-Fi module, and the network node 200 and the network node 300 are base stations and routers, respectively. The wireless communication module 1 and the wireless communication module 2 are both cellular network modules, and the network node 200 and the network node 300 may be base stations of different operators.

In some embodiments, the electronic device 100 may use the wireless communication module 1 to send uplink data to the network node 200, and use the wireless communication module 2 to receive downlink data from the network node 300. Then, the transmission of the antenna in the wireless communication module 1 may cause harmonic interference or adjacent frequency interference to the reception of the antenna in the wireless communication module 2.

In some embodiments, the electronic device 100 may use the wireless communication module 1 to receive downlink data from the base station 200, and use the wireless communication module 2 to send uplink data to the router 300 using Wi-Fi. At this time, the transmission of the antenna in the wireless communication module 2 may cause adjacent frequency interference to the reception of the antenna in the wireless communication module 1.

Next, referring to the types of wireless communication modules 1 and wireless communication modules 2 shown in Table 1, application scenarios of electronic device communication are described.

Table 1:

Application Scenario Wireless communication module 1 Wireless communication module 2 Application Scenario(1) Cellular network module Wi-Fi Module Application Scenarios(2) Cellular network module Bluetooth module Application Scenarios(3) Cellular network module Cellular network module Application Scenarios(4) Wi-Fi Module Bluetooth module

For example, application scenario (1) may include: Wi-Fi Internet access and cellular network calls, Wi-Fi hotspot sharing and cellular network data services, distributed communications, multi-network collaboration, and other scenarios.

For example, application scenario (2) may include: cellular network Internet access and Bluetooth data transmission, cellular network calls and Bluetooth data transmission, distributed communications, multi-network collaboration, and other scenarios.

For example, application scenario (3) may include: surfing the Internet on one cellular network and talking on another cellular network, talking on two cellular networks separately, distributed communication, multi-network collaboration, etc. At this time, the electronic device 100 may support dual-SIM dual-standby, such as installing two subscriber identity modules (SIM) cards of two different operators at the same time to support the electronic device 100 to run two cellular network modules.

For example, application scenario (4) may include: Wi-Fi Internet access and Bluetooth data transmission, distributed communication, multi-network collaboration and other scenarios.

In some embodiments, in application scenarios (1), (2), and (4), wireless communication module 1 and wireless communication module 2 each have an independent antenna system. In application scenario (3), wireless communication module 1 and wireless communication module 2 may share a group of antenna systems, for example, module A and module B may respectively lock different antennas in the same antenna system.

In some embodiments, whether the coexistence interference between wireless communication module 1 and wireless communication module 2 is harmonic interference or adjacent frequency interference depends on the operating frequency bands of the two modules. For example, when the two modules respectively operate in the second harmonic of the 2.4G frequency band of the Wi-Fi network and N79 of the 5G cellular network, the coexistence interference between the two wireless communication modules is harmonic interference. For another example, when the two modules respectively operate in the 2.4G frequency band of the Wi-Fi network and N41 of the cellular network, the coexistence interference between the two wireless communication modules is adjacent frequency interference.

It can be understood that each coexistence frequency band in the present application is a combination of two working frequency bands (or frequency combinations), that is, a working frequency band of wireless communication module 1 and a working frequency band of wireless communication module 2. Then, each coexistence frequency band can be used for a coexistence scenario in which two wireless communication modules work at the same time and there is coexistence interference. When the working frequency band of wireless communication module 1 and the working frequency band of wireless communication module 2 in the electronic device 100 fall into a certain coexistence frequency band at the same time, it means that the two modules are in a coexistence scenario in which there is coexistence interference.

As an example, corresponding to adjacent frequency interference, the difference between the maximum value of one frequency band and the minimum value of another frequency band is less than or equal to a preset difference, wherein the preset difference may be an empirical value or an experimental value, which is not specifically limited in this application.

As an example, corresponding to harmonic interference, the difference between an integer multiple of a range maximum value of one frequency band and a range minimum value of another frequency band is less than or equal to a preset difference.

In some embodiments, wireless communication module 1 and wireless communication module 2 may have different antenna combinations, and the two wireless communication modules may use multiple working frequency band combinations under the same antenna combination, that is, the same antenna combination between the two wireless communication modules may correspond to multiple coexistence frequency bands.

It is understandable that a wireless communication module can use the same antenna at some operating frequencies, for example, a cellular network module can use the same antenna at B40, B41, and N41 frequency bands. In addition, the antenna used by a wireless communication module at some operating frequency bands is different from the antenna used at other operating frequencies, for example, the antenna used by the cellular network module at the N41 frequency band is different from the antenna used at the N79 frequency band.

In some embodiments, in order to facilitate the management of pre-set coexistence frequency bands, multiple coexistence frequency bands using the same antenna combination between two wireless communication modules can be classified into the same type. The type of coexistence frequency band can also be called a gear, and a gear includes multiple coexistence frequency bands.

In some embodiments, the present application may regard the coexistence bands composed of the B40, B41, and N41 bands of the cellular network module and the 2.4G band of the Wi-Fi module as the same type of coexistence bands, which may be called the coexistence bands of the 2.4G adjacent frequency type. In addition, since the antenna used by the N79 band is different from that used by the N41 band, the coexistence band composed of the N79 band of the cellular network module and the 2.4G band of the Wi-Fi module does not belong to the 2.4G adjacent frequency type.

Next, referring to Table 2, examples of various coexistence frequency bands of the 2.4G adjacent frequency type are shown.

Table 2:

The coexistence frequency bands 1 to 3 shown in Table 2 may respectively indicate coexistence scenarios 1 to 3, that is, three scenarios in which coexistence interference exists between the wireless communication module 1 and the wireless communication module 2 .

In some embodiments, each coexistence frequency band shown in Table 2 includes a working frequency band and a corresponding channel number of wireless communication module 1, and a working frequency band and a corresponding channel number of wireless communication module 2. Usually, the working frequency band corresponding to a channel is fixed.

Among them, the coexistence band 3 in Table 2 indicates that the working frequency band of the wireless communication module 1 is 2496-2565 Hz, and the corresponding channel is the N41 low channel of 499200-51300. The coexistence band 3 indicates that the working frequency band of the wireless communication module 2 is 2447-2482 Hz, and the corresponding channel number is the wireless local area network (WLAN) high channel of CH8-CH13. For example, in the coexistence scenario 3 indicated by the coexistence band 3, the uplink data transmission of the wireless communication module 1 in the N41 frequency band will cause adjacent channel interference to the downlink data reception of the wireless communication module 2 in the Wi-Fi 2.4G frequency band.

Similarly, for the related descriptions of the coexistence frequency band 1 and the coexistence frequency band 2 in Table 3, reference may be made to the related descriptions of the coexistence frequency band 3, which will not be described in detail.

In some embodiments, taking the coexistence scenario 3 indicated by the coexistence frequency band 3 as an example, the wireless communication module and its communication method are specifically described.

As shown in FIG2 , it is a schematic diagram of the antenna structure of a wireless communication module 1 and a wireless communication module 2 provided in an embodiment of the present application.

In Figure 2, the wireless communication module 1 can work in the cellular network N41 frequency band, and the corresponding antenna specification is 1TX/4RX. At this time, module 1 includes four antennas Ant0 to Ant3, all of which can work as RX, and one of the antennas can be scheduled to work as TX. As an example, the scheduling of TX on these four antennas is mainly determined by the received signal strength of the four antennas, such as polling the four antennas to obtain the reference signal receiving power (RSRP) respectively, so as to select the antenna with the largest RSRP as TX.

RSRP is the received signal strength index, which indicates the average power received in a specific cellular network cell. If the RSRP value is very low, it means that the received signal strength is very weak, and the user experience will be very poor. For example, the RSRP value range is -140 to -40, in decibel relative to one milliwatt (dBm). -140dBm indicates the weakest signal, and -40dBm indicates the strongest signal.

The wireless communication module 2 in FIG2 can work in the 2.4G frequency band of Wi-Fi, and the corresponding antenna specification is 2TRX. Among them, module 2 includes two antennas, Ant4 and Ant5, and these two antennas work as RX or TX. Obviously, the two wireless communication modules shown in FIG2 are both multi-antenna systems.

It can be understood that, since the antenna combination between the two wireless communication modules in the electronic device corresponding to the same type of coexistence frequency band is unchanged, the same multiple strength attenuation values can be set for one of the wireless communication modules of the electronic device for the same type of coexistence frequency band. That is, for one of the wireless communication modules of the electronic device, multiple coexistence frequency bands of the same type correspond to the same multiple strength attenuation values.

The antenna combination shown in FIG. 2 is used below to illustrate the isolation, sensitivity degradation and antenna strength attenuation value of the two wireless communication modules in the present application.

In some embodiments, the antenna isolation is described by taking the antennas in the wireless communication module 1 and the wireless communication module 2 in the coexistence scenario 3 as an example. Referring to Table 3, an example of the antenna isolation between the wireless communication module 1 and the wireless communication module 2 provided in the embodiment of the present application is shown.

Table 3:

Antenna Isolation Ant0 Ant1 Ant2 Ant3 Ant4 Difference Difference middle excellent Ant5 middle Difference excellent excellent

Among them, for antennas Ant4 and Ant5 in wireless communication module 2, the isolation of antenna Ant3 in wireless communication module 1 is the best, and the isolation of antenna Ant1 is the worst. Then, in order to avoid strong interference to the reception of wireless communication module 2, before performing antenna scheduling on wireless communication module 1, the received signal strength of antenna Ant1 can be adjusted to avoid the antenna from being scheduled, thereby avoiding the transmission of antenna Ant1 causing strong interference to the reception of antenna Ant4 or Ant5.

The deterioration of receiver sensitivity is called desense. The receiver sensitivity is determined by the channel bandwidth and the signal-to-noise ratio. For example, a 5MHz bandwidth is 3dB better than a 10MHz bandwidth in theory. The unit is decibel (dB).

In some implementations, the present application can pre-set the sensitivity degradation value of each antenna based on antenna isolation. For example, referring to Table 4, an example of sensitivity degradation of the antenna between the wireless communication module 1 and the wireless communication module 2 in the electronic device 100 provided in an embodiment of the present application is shown.

Table 4:

Desense Ant0 Ant1 Ant2 Ant3 Ant4 9dB 9dB 6dB 0dB Ant5 6dB 9dB 0dB 0dB

Combining Table 3 and Table 4, it can be seen that for antenna Ant4, the sensitivity deterioration value of Ant3 in the wireless communication module 1 is the smallest, and the sensitivity deterioration values of antennas Ant0 and Ant1 are the largest. For antenna Ant5, the sensitivity deterioration values of antennas Ant2 and Ant3 in the wireless communication module 1 are the smallest, and the sensitivity deterioration value of antenna Ant1 is the largest.

In some embodiments, the present application may pre-configure different strength attenuation values for each first antenna in the wireless communication module 1 according to the sensitivity degradation value of the antenna between the wireless communication module 1 and the wireless communication module 2. For example, in coexistence scenarios 1 to 3, the present application may pre-configure each strength attenuation value for the antennas Ant0 to Ant3 of the wireless communication module 1 based on the sensitivity degradation value shown in Table 4 above.

For example, Table 5 shows an example of strength attenuation values of antennas Ant0 to Ant3 in the wireless communication module 1 in coexistence scenarios 1 to 3.

Table 5:

The electronic device 100 can adjust the received signal strength values of antennas Ant0 to Ant3 according to the respective strength attenuation values of antennas Ant0 to Ant3 shown in Table 5. The strength attenuation value corresponding to antenna Ant1 is the largest and the received signal strength value after adjustment is reduced to the greatest extent, and the strength attenuation value corresponding to antenna Ant3 is the smallest and the received signal strength value after adjustment is reduced to the smallest extent.

For example, the wireless communication module 1 is a cellular network module, and the received signal strength value of the first antenna may be RSRP. The wireless communication module 1 is a Wi-Fi module, and the received signal strength value of the first antenna may be a received signal strength indicator (RSSI).

RSSI indicates the signal strength in a wireless network. It decays with increasing distance and is usually a negative value. The closer the value is to zero, the higher the signal strength. For example, the RSSI value range is -140 to -10, and the unit is dBm.

In some embodiments, the reference for setting different strength attenuation values for different antennas in the present application may be 0dB, that is, the strength attenuation value set for the antenna with the smallest sensitivity degradation value may be 0dB. Correspondingly, the strength attenuation value set for the antenna with a larger sensitivity degradation value may be a value greater than 0, such as 3dB.

In some embodiments, the present application can not only pre-set multiple strength attenuation values for multiple antennas in the wireless communication module 1 in the electronic device 100, but also set corresponding multiple strength attenuation values for multiple second antennas in the wireless communication module 2 when multiple second antennas are included in the wireless communication module 2. For example, in the scenario where the transmission of the wireless communication module 2 causes adjacent frequency interference to the reception of the wireless communication module 1, the present application can set corresponding strength attenuation values for both communication modules.

For the convenience of distinction, the following embodiments refer to the multiple strength attenuation values corresponding to the multiple first antennas in the wireless communication module 1 as multiple first strength attenuation values; and refer to the multiple strength attenuation values corresponding to the multiple second antennas in the wireless communication module 2 as multiple second strength attenuation values. That is, for each type of multiple coexisting frequency bands, the present application can set multiple first strength attenuation values for the multiple first antennas in the wireless communication module 1, and set multiple second strength attenuation values for the multiple second antennas in the wireless communication module 2.

Similarly, in some embodiments, the present application may pre-configure different strength attenuation values for each antenna in the wireless communication module 2 in the electronic device 100 based on the sensitivity degradation value of the antenna between the two wireless communication modules.

In some embodiments, under coexistence scenarios 1 to 3, the present application may pre-configure respective strength attenuation values for antennas Ant4 and Ant5 in the wireless communication module 2 based on the sensitivity degradation values shown in Table 4 above.

For example, Table 6 shows an example of strength attenuation values of antennas Ant4 and Ant5 in the wireless communication module 2 in coexistence scenarios 1 to 3.

Table 6:

It can be understood that the electronic device 100 can adjust the received signal strength values of antennas Ant4 and Ant5 with the respective strength attenuation values of antennas Ant4 and Ant5 shown in Table 6 to schedule antenna work from antennas Ant4 and Ant5. Among them, the strength attenuation value of antenna Ant4 is greater than the strength attenuation value of antenna Ant5, so the received signal strength of antenna Ant5 after adjustment may be greater than the received signal strength of antenna Ant4 after adjustment.

For example, when the wireless communication module 2 communicates based on a cellular network, the received signal strength value of the second antenna may be RSRP. For example, when the wireless communication module 2 communicates based on Wi-Fi, the received signal strength value of the second antenna may be RSSI.

In addition, in some embodiments, when the wireless communication module 1 and the wireless communication module 2 are in a non-coexistence scenario, that is, the respective operating frequency bands of the two wireless communication modules do not fall into any coexistence frequency band at the same time, a default strength attenuation value is set for each of the multiple antennas of the wireless communication module 1.

In some embodiments, the default strength attenuation values set for different first antennas in the present application are all the same. For example, each default strength attenuation value is 0 dB, or 1 dB, etc., but is not limited thereto.

For example, Table 7 shows an example of default strength attenuation values of antennas Ant0 to Ant3 in the wireless communication module 1 , that is, each default strength attenuation value is 0 dB.

Table 7:

In some embodiments, when the wireless communication module 1 and the wireless communication module 2 are in a non-coexistence scenario, a default strength attenuation value may be set for each of the multiple antennas of the wireless communication module 2 .

For example, Table 8 shows an example of default strength attenuation values of antennas Ant4 and Ant5 in the wireless communication module 2 , and each default strength attenuation value is 0 dB.

Table 8:

Next, a flow chart of a communication method of the present application is shown with reference to FIG3 , and the execution subject of the method may be an electronic device 100. The method may be applied to a scenario in which the first antenna is scheduled from the wireless communication module 1 to send uplink data when the electronic device 100 uses the wireless communication module 2 to receive downlink data. Specifically, the method includes the following steps:

S301: The electronic device 100 obtains a preset coexistence frequency band, and a plurality of first intensity attenuation values corresponding to a plurality of first antennas of each type of coexistence frequency band.

The aforementioned pre-set multiple coexistence frequency bands may include multiple types of coexistence frequency bands, such as the 2.4G adjacent frequency type coexistence frequency bands shown in Table 2 above.

S302: The electronic device 100 obtains the working frequency band of the wireless communication module 1.

In some embodiments, when the wireless communication module 2 of the electronic device 100 is in a receiving state and the wireless communication module 1 needs to enter a transmitting state, the transmission data of multiple first antennas in the wireless communication module 1 may interfere with the reception data of at least one second antenna in the wireless communication module 2.

For example, the wireless communication module 1 is a cellular network module and the operating frequency band is 2496-2565 Hz, that is, the module 1 operates in the cellular network N41 low channel 499200-51300.

S303: The electronic device 100 obtains the working frequency band of the wireless communication module 2.

In some other embodiments, the present application may also execute S303 first and then execute S302, or execute S302 and S303 at the same time, which is not limited to this.

For example, the wireless communication module 2 is a Wi-Fi module and its operating frequency band is 2447-2482 Hz, that is, the module 2 operates in the WLAN high channels CH8-CH13.

S304: The electronic device 100 determines whether the working frequency band of the wireless communication module 1 and the working frequency band of the wireless communication module 2 belong to a coexistence frequency band. If the working frequency band of the wireless communication module 1 and the working frequency band of the wireless communication module 2 belong to any coexistence frequency band, the process proceeds to S305. If they do not belong to any coexistence frequency band, the process proceeds to S307.

It can be understood that whether the working frequency band of the wireless communication module 1 and the working frequency band of the wireless communication module 2 belong to a coexistence frequency band can be used as an interference condition. When the working frequency band of the wireless communication module 1 and the working frequency band of the wireless communication module 2 belong to any coexistence frequency band, the interference condition is satisfied, indicating that there is coexistence interference between the two modules. On the contrary, the interference condition is not satisfied, indicating that there is no coexistence interference between the two modules.

As an example, when the working frequency band of the wireless communication module 1 is the frequency band 2496-2565 Hz under the N41 low channel 499200-51300, and the working frequency band of the wireless communication module 2 is the frequency band 2447-2482 Hz under the WLAN high channel CH8-CH13, the electronic device 100 determines that the two working frequency bands belong to the coexistence frequency band 3 in Table 2, that is, the two modules work in the coexistence scenario 3 corresponding to the coexistence frequency band 3. At this time, there is adjacent frequency interference between the two wireless communication modules.

S305: corresponding to the operating frequency band of the wireless communication module 1 and the operating frequency band of the wireless communication module 2 belonging to the target coexistence frequency band, the electronic device 100 obtains a plurality of first strength attenuation values corresponding to the plurality of first antennas.

The multiple first strength attenuation values acquired by the electronic device 100 correspond one-to-one to the multiple first antennas, and the multiple first strength attenuation values are multiple first strength attenuation values corresponding to the type to which the target coexistence frequency band belongs.

The target coexistence frequency band may be one of the pre-set coexistence frequency bands. For example, when the operating frequency bands of the wireless communication module 1 and the wireless communication module 2 respectively meet the coexistence frequency band 3 shown in Table 2, that is, when the two modules are in scenario 3, the electronic device 100 obtains multiple first strength attenuation values of multiple first antennas corresponding to the coexistence frequency band 3, such as the multiple strength attenuation values shown in Table 5.

S306: The electronic device 100 adjusts the received signal strength values of each first antenna based on the first strength attenuation value corresponding to each first antenna in the wireless communication module 1 to obtain the adjusted received signal strength values of each first antenna.

For example, when the wireless communication module 1 is a cellular network module, the received signal strength values of the multiple first antennas may be RSRP. Then, the electronic device 100 may adjust the RSRP of each first antenna, such as by subtracting the corresponding first strength attenuation value from the RSRP of each first antenna to obtain the adjusted RSRP of each first antenna. The greater the strength attenuation value of the antenna with poor antenna isolation, the greater the RSRP of the antenna with poor antenna isolation among the multiple first antennas in the wireless communication module 1, so as to avoid the antenna from being scheduled as much as possible.

As an example, referring to the antenna combination shown in FIG2 and the strength attenuation values of each first antenna shown in Table 5, the electronic device 100 can obtain the RSRP of antennas Ant0 to Ant3, and subtract the corresponding strength attenuation values from the RSRP of antennas Ant0 to Ant3 to obtain the adjusted RSRP of antennas Ant0 to Ant3. For example, the RSRP of antenna Ant1 obtained by the electronic device 100 is -80dBm and the adjusted RSRP is -89dBm, so as to avoid antenna Ant1 being scheduled for work as much as possible.

For example, when the wireless communication module 1 is a Wi-Fi module, the received signal strength values of the multiple first antennas of the wireless communication module 1 are RSSI. Similarly, the electronic device 100 can adjust the RSSI of each first antenna in the wireless communication module 1 according to the corresponding strength attenuation value, and the specific adjustment can refer to the RSRP adjustment mentioned above, which will not be repeated here.

S307: corresponding to the operating frequency band of the wireless communication module 1 and the operating frequency band of the wireless communication module 2 not satisfying any coexistence frequency band, the electronic device 100 obtains a default strength attenuation value corresponding to each first antenna.

In some embodiments, when the wireless communication module 1 and the wireless communication module 2 are in a non-coexistence scenario, the first default strength attenuation value of each first antenna in the wireless communication module 1 is 0 dB, such as the multiple strength attenuation values shown in Table 7.

S308: The electronic device 100 adjusts the received signal strength values of each first antenna based on the default strength attenuation value corresponding to each first antenna in the wireless communication module 1 to obtain the adjusted received signal strength values of each first antenna.

For example, when the default strength attenuation value corresponding to each first antenna is 0 db, the unadjusted received signal strength value and the adjusted received signal strength value of each first antenna are the same, which is equivalent to the electronic device 100 not adjusting the received signal strength value of each first antenna.

Among them, the above S305 and S306 and S307 and S308 are two parallel processing flows, and after the execution of S306 and S308, both enter the following S309.

Then, the processing logic of the above S305 and S306 is consistent with that of S307 and S308, and the same code can be reused in actual application, thereby improving the execution efficiency of the antenna scheduling process.

S309 : the electronic device 100 performs first antenna scheduling based on the adjusted received signal strength values of each first antenna in the wireless communication module 1 .

In some embodiments, the electronic device 100 can schedule at least one antenna from multiple first antennas of the wireless communication module 1 to work as TX, that is, it can schedule multiple antennas with good antenna isolation and large received signal strength values to transmit.

For example, when two wireless communication modules are in coexistence scenarios 1 to 3, the electronic device 100 can schedule one antenna in the wireless communication module 1 as TX to send uplink data to the base station 200 .

In some embodiments, the wireless communication module 1 is a cellular network module, and the electronic device 100 can compare the adjusted RSRPs of antennas Ant0 to Ant3, and select the antenna with the largest RSRP to work. For example, the unadjusted RSRP of antenna Ant1 is -80dBm, and the adjusted RSRP is -89dBm after subtracting the corresponding strength attenuation value of 9dBm. In addition, referring to the strength attenuation values shown in Table 5, compared with the strength attenuation values of antennas Ant0, Ant2, and Ant3, the strength attenuation value of antenna Ant1 is the largest, so the RSRP of antenna Ant1 after adjustment is the largest, so antenna Ant1 is usually not scheduled.

When the wireless communication module 1 and the wireless communication module 2 are in a non-coexistence scenario, since the default strength attenuation value of each antenna in the wireless communication module 1 is 0 dB, the default strength attenuation value of each antenna will not affect the RSRP of each antenna. At this time, the electronic device 100 actually performs antenna scheduling according to the RSRP actually calculated for each antenna in the wireless communication module 1.

It can be understood that the greater the first strength attenuation value corresponding to the first antenna in the present application, the greater the degree of reduction in its received signal value. However, affected by the size of the unadjusted received signal strength value of each first antenna, the first antenna with the largest adjusted received signal strength value may not be the first antenna with the smallest first strength attenuation value, that is, the first antenna with the largest adjusted received signal strength value may not be the first antenna with the highest antenna isolation. At this time, the electronic device can schedule the first antenna with better antenna isolation in the wireless communication module 1 to work, so as to achieve the purpose of optimizing interference.

In this way, the present application schedules the first antenna by comprehensively considering the received signal strength and antenna isolation of the first antenna to schedule the first antenna to work with the least actual interference. For example, the first antenna scheduled by the electronic device is not the first antenna with the highest antenna isolation among multiple first antennas, but the first antenna with the second highest antenna isolation.

In the coexistence scenario where the transmission of the wireless communication module 1 affects the reception of the wireless communication module 2, the present application can configure each first strength attenuation value for the multiple first antennas in the wireless communication module 1 according to the coexistence scenario, and adjust the received signal strength of each first antenna according to these strength attenuation values. Thus, the received signal strength of the antenna with poor antenna isolation among the multiple first antennas is reduced to the greatest extent, and the first antenna with poor antenna isolation is avoided from being scheduled as much as possible. Thus, the coexistence interference caused by the transmission of the wireless communication module 1 to the reception of the wireless communication module 2 is weakened, and the communication quality of the wireless communication module 2 is improved.

Referring to Figure 4, a flow chart of a communication method provided in an embodiment of the present application is shown. The difference between the method shown in Figure 4 and the method shown in Figure 3 is that S307 and S308 in Figure 4 are replaced by S310, that is, the branches S307 to S309 shown in Figure 3 are replaced by S310.

S301 to S306, and S309. S301 to S306 and S309 shown in FIG4 are the same as S301 to S306 and S309 shown in FIG3, and are not described in detail here.

S310: Corresponding to the fact that the working frequency band of the wireless communication module 1 and the working frequency band of the wireless communication module 2 do not belong to any coexistence frequency band, the electronic device 100 performs antenna scheduling according to the received signal strength values of each first antenna in the wireless communication module 1. At this time, the received signal strength value of the first antenna is the received signal strength value actually calculated by the electronic device 100.

For example, when the wireless communication module 1 is a cellular network module, the electronic device 100 can perform antenna scheduling according to the RSRP actually calculated for each first antenna in the wireless communication module 1. Similarly, when the wireless communication module 1 is a Wi-Fi module, the electronic device 100 can perform antenna scheduling according to the RSSI actually calculated for each first antenna in the wireless communication module 1.

In some embodiments, in the above coexistence scenarios 1 to 3, the electronic device 100 schedules a first antenna in the wireless communication module 1 to work as TX, that is, calls an antenna with higher antenna isolation to work as TX.

In this way, the steps of adjusting the received signal strength of each antenna in the wireless communication module 1 in a non-coexistence scenario are reduced, and the conventional process of antenna scheduling according to the received signal strength value actually calculated by the antenna can be combined to improve the antenna scheduling efficiency.

In some embodiments, the present application can determine whether the start-up mechanism is satisfied by determining the state of the wireless communication module 2 in the electronic device 100. For example, when the received signal strength of the antenna of the wireless communication module 2 is weak and there is interference, it is determined that the start-up mechanism is satisfied, otherwise it is not satisfied.

5 is a schematic diagram of a scene recognition startup mechanism judgment process shown in an embodiment of the present application, and the execution subject of the method is still the electronic device 100. The method provided by the present application may further include the startup mechanism defined by S501 and S502 before S301 or S302 shown in FIG3 , and FIG5 takes the example of including S501 and S502 before S302 shown in FIG3 .

Specifically, the process shown in FIG5 includes the following steps:

S301, wherein S301 is the same as S301 in FIG3 and will not be described in detail here.

S501: the electronic device 100 obtains the received signal strength value and signal to noise ratio (SNR) of each second antenna in the wireless communication module 2.

Among them, SNR refers to the ratio of the strength of the received useful signal to the strength of the received interference signal (noise), reflecting the link quality of the current channel, that is, the degree of interference to the current channel. For example, the value range of SNR is -20 to 50, in decibels (dB), and the larger the value, the better.

In some embodiments, the electronic device 100 may periodically monitor the antenna status of each second antenna, and monitor the received signal strength value and SNR of the second antenna when the second antenna is in a receiving state.

In some other embodiments, the electronic device 100 does not need to additionally obtain the state information of the second antenna, and can directly monitor and obtain the received signal strength value and SNR of the second antenna, which will not be described in detail.

It can be understood that the state of the antenna is used to indicate whether the antenna works as a TX or as a RX. When the antenna works as an RX to receive data, the received signal strength value and SNR of the antenna can be detected.

For example, the wireless communication module 2 is a cellular network module, and the received signal strength values of the plurality of second antennas are RSRP. The wireless communication module 2 is a Wi-Fi module, and the received signal strength values of the plurality of second antennas are RSSI.

S502: The electronic device 100 determines whether the received signal strength value of at least one second antenna in the wireless communication module 2 is less than the first threshold and the SNR is less than the second threshold. If yes, it proceeds to S302, if not, it returns to S501 and continues to monitor the receiving status of the antenna in the current wireless communication module 2.

For example, in coexistence scenario 3, the antenna specification of the wireless communication module 2 is 2TRX, that is, as shown in FIG2 , the wireless communication module 2 includes two RXs. Then, in S502, the electronic device 100 can determine whether the RSSI of one of the two RXs of the wireless communication module 2 is less than the first threshold and the SNR is less than the second threshold.

It can be understood that if the received signal strength of the antenna is less than the first threshold, it means that the wireless communication module 2 currently has a weak signal, and if the SNR is less than the second threshold, it means that it is currently interfered with. That is, the current wireless communication module 2 has a weak signal and is interfered with, that is, the current reception of the wireless communication module 2 may be interfered with by the coexistence caused by the transmission of the wireless communication module 1.

As an example, when the received signal strength of each second antenna is RSSI, the first threshold is -75, that is, the RSSI of the antenna is less than -75 dBm. The second threshold is 20, that is, the SNR of the antenna is less than 20 dB.

S302 to S309: S302 to S309 are the same as S302 to S309 in FIG3 , and will not be described in detail here.

Then, only when it is determined that the current wireless communication module 2 has a weak signal and is interfered with, operations such as coexistence scenario recognition and strength attenuation value configuration will be performed, which is beneficial to improving the execution efficiency of the antenna scheduling process in the communication method.

It can be understood that when the above startup mechanism is satisfied, the electronic device 100 can directly obtain the working frequency bands of the two wireless communication modules and execute the communication method corresponding to S302 to S308 as shown in FIG. 3 .

In some embodiments, after the above startup mechanism is satisfied and the working frequency bands of the two wireless communication modules are initially acquired, the electronic device 100 may acquire the working frequency bands of the two wireless communication modules again when it detects that the status of one of the wireless communication modules has changed.

In some embodiments, the above S302 and S303 can be replaced by S302a and S303a, respectively. For example, based on FIG3 , referring to the method shown in FIG6 , the above S302 and S303 can be replaced by S302a and S303a, respectively. Hereinafter, the same steps and related descriptions of the method shown in FIG6 and the method shown in FIG3 will not be repeated.

S301, wherein the S301 is the same as the S301 shown in FIG. 3.

S302a: When the state of the wireless communication module 1 changes, the electronic device 100 obtains the working frequency band of the wireless communication module 1 .

In some embodiments, the electronic device 100 can monitor the state change of the wireless communication module 1, such as monitoring in a periodic manner, to determine whether there is a change in the wireless communication module 1. The period setting can be set according to actual needs and is not specifically limited here.

In some embodiments, when the wireless communication module 1 is a cellular network module and the cell changes, it indicates that the state of the wireless communication module 1 has changed. It can be understood that when the cell of the cellular network changes, such as when a cell switching occurs, the channel on which the wireless communication module 1 works usually changes, and the corresponding working frequency band changes.

Usually, the electronic device 100 will monitor the neighboring cells after connecting to the serving cell. When it is found that the neighboring cell can stably provide better signal quality than the serving cell, the better cell will be selected as the serving cell, that is, cell switching occurs.

In some embodiments, the electronic device 100 may obtain cell information (cell info), that is, information of the cell (i.e., serving cell) where the electronic device 100 is currently located. The cell information generally includes a cell ID, a channel, a physical cell identifier (PCI), and the like.

As an example, the electronic device 100 can determine that the current cell has changed through the change of the cell ID or PCI in the current cell information. Then, when the cell of the electronic device 100 changes, the channel information corresponding to the current cell is obtained to obtain the corresponding working frequency band.

S303a: When the state of the wireless communication module 2 changes, the electronic device 100 obtains the working frequency band of the wireless communication module 2.

In some embodiments, the electronic device 100 can monitor the state change of the wireless communication module 2, such as monitoring in a periodic manner, to determine whether there is a change in the wireless communication module 2. The period setting can be set according to actual needs and is not specifically limited here.

In some embodiments, when the wireless communication module 2 is a Wi-Fi module and the WLAN is connected to 2.4G or the Wi-Fi status changes, the electronic device 100 can obtain the working frequency band of the wireless communication module 2 .

It can be understood that when the WLAN of the Wi-Fi module is connected to 2.4G or the Wi-Fi status changes, it means that the working frequency band of module B has changed. Then, when the wireless communication module 2 is a Wi-Fi module, the WLAN channel information of the wireless communication module 2 can be obtained to know the corresponding working frequency band. For example, the wireless communication module 2 works in the frequency band range of [2447~2482], that is, it works in the WLAN high channel CH8~CH13.

As an example, Wi-Fi connected to 2.4G means that the wireless communication module 2 is connected to channels CH1 to CH5 or channels CH8 to CH13. The Wi-Fi status changes, which means that the wireless communication module 2 switches from channels CH1 to CH5 to channels CH8 to CH13, or from channels CH8 to CH13 to channels CH1 to CH5.

It can be understood that when the state of at least one wireless communication module in the electronic device 100 changes and it is determined that two wireless communication modules simultaneously fall into another coexistence frequency band of the same type, it is possible to reacquire multiple strength attenuation values corresponding to the type, or no longer reacquire these strength attenuation values.

It can be understood that when the state of at least one wireless communication module in the electronic device 100 changes and it is determined that two wireless communication modules simultaneously fall into another coexistence frequency band of different types, multiple strength attenuation values corresponding to the new type can be re-acquired.

In some embodiments, as shown in Figure 7, a schematic diagram of the configuration process of the strength attenuation value of an antenna is provided for an embodiment of the application. Figure 7 shows that when the wireless communication module 1 and the wireless communication module 2 change from a non-coexistence scenario to a coexistence scenario in coexistence scenarios 1 to 3, the strength attenuation value of each first antenna (i.e., antenna Ant0 to Ant3) in the wireless communication module 1 is configured from the default strength attenuation value to a plurality of first strength attenuation values corresponding to the coexistence frequency band of the 2.4G adjacent frequency type, such as the plurality of strength attenuation values shown in Table 6 are adjusted to the plurality of strength attenuation values shown in Table 5.

In this way, the present application can monitor the status changes of two wireless communication modules in an electronic device in real time, and monitor in real time whether the respective working frequency bands of the two wireless communication modules fall into a new coexistence frequency band at the same time, and can re-acquire the corresponding new multiple intensity attenuation values, which is conducive to optimizing the coexistence interference between the two wireless communication modules.

It can be understood that when the wireless communication module 1 and the wireless communication module 2 in the electronic device 100 both include multiple antennas, the present application can simultaneously adjust the received signal strength of each antenna in the two wireless communication modules to avoid the antenna combination with strong interference in the two modules from being selected, thereby further optimizing the coexistence interference.

In some embodiments, as shown in FIG. 8 , the present application provides a flow chart of a communication method, the execution subject is still the electronic device 100. Specifically, the method includes the following steps:

S801: The electronic device 100 obtains a preset coexistence frequency band, and a plurality of first intensity attenuation values corresponding to a plurality of first antennas and a plurality of second intensity attenuation values corresponding to a plurality of second antennas of each type of coexistence frequency band.

The difference between S801 and S301 shown in FIG. 3 is that the electronic device 100 additionally stores a plurality of second strength attenuation values of a plurality of second antennas of the wireless communication module 2 .

S802 to S804: S802 to S804 are the same as S302 to S304 in FIG3 .

S805: When the working frequency band of the wireless communication module 1 and the working frequency band of the wireless communication module 2 meet the target coexistence frequency band, the electronic device 100 obtains the first strength attenuation value of each first antenna corresponding to the target coexistence frequency band, and the second strength attenuation value of each second antenna corresponding to the target coexistence frequency band.

As an example, when the respective operating frequency bands of the wireless communication module 1 and the wireless communication module 2 satisfy the coexistence frequency band 3 shown in Table 2, that is, when the two modules are in scene 3, the electronic device 100 obtains multiple first intensity attenuation values shown in Table 5 and multiple second intensity attenuation values shown in Table 6.

S806: The electronic device 100 adjusts the received signal strength values of each first antenna based on the first strength attenuation value of each first antenna in the wireless communication module 1, and adjusts the received signal strength values of each second antenna based on the second strength attenuation value of each second antenna in the wireless communication module 2, to obtain the adjusted received signal strength values of each first antenna and each second antenna.

For example, the wireless communication module 1 is a cellular network module and the wireless communication module 2 is a Wi-Fi module. The received signal strength values of the first antennas of the wireless communication module 1 may be RSRP, and the received signal strength values of the second antennas of the wireless communication module 2 may be RSSI.

In some embodiments, the electronic device 100 may adjust the RSRP of each first antenna, such as subtracting the first strength attenuation value of each first antenna from the original RSRP of each antenna in module A to obtain the adjusted RSRP of each antenna. Similarly, the electronic device 100 may adjust the RSSI of each second antenna, such as subtracting the second strength attenuation value of each second antenna from the RSSI of each second antenna in the wireless communication module 2 to obtain the adjusted RSSI of each second antenna.

S807: Corresponding to the working frequency band of the wireless communication module 1 and the working frequency band of the wireless communication module 2 not satisfying any coexistence frequency band, the electronic device 100 obtains the default strength attenuation value of each antenna in the wireless communication module 1 and the default strength attenuation value of each antenna in the wireless communication module 2.

For example, the server 200 sends a plurality of strength attenuation values as shown in Table 7 and a plurality of strength attenuation values as shown in Table 8 to the electronic device 100 .

S808: The electronic device 100 adjusts the received signal strength values of each first antenna based on the default strength attenuation value of each first antenna in the wireless communication module 1, and adjusts the received signal strength values of each second antenna based on the default strength attenuation value of each second antenna in the wireless communication module 2, to obtain the adjusted received signal strength values of each first antenna and each second antenna.

For example, the default strength attenuation value corresponding to each first antenna and the default strength attenuation value corresponding to each second antenna are both 0 db, which is equivalent to that the electronic device 100 does not adjust the received signal strength values of each first antenna and each second antenna.

S809: The electronic device 100 performs antenna scheduling on multiple first antennas based on the adjusted received signal strength values of each first antenna in the wireless communication module 1, and performs antenna scheduling on multiple second antennas based on the adjusted received signal strength values of each second antenna in the wireless communication module 2.

In some embodiments, the electronic device 100 schedules at least one first antenna from multiple first antennas of the wireless communication module 1 to work as TX, that is, to transmit data; and schedules at least one second antenna from multiple second antennas of the wireless communication module 2 to work as RX, that is, to receive data.

For example, in coexistence scenario 3, the electronic device 100 schedules a first antenna in the wireless communication module 1 to work as TX, and schedules a second antenna in the wireless communication module 2 to work as RX.

In some embodiments, the electronic device 100 can compare the adjusted SNR and RSRP of antennas Ant0 to Ant3, and select the first antenna with the largest RSRP to work. In addition, the electronic device 100 can compare the adjusted SNR of antennas Ant4 and Ant5, and select the second antenna with the largest RSSI to work.

As an example, referring to Table 5, it can be seen that the RSRP of antenna Ant1 after adjustment is the largest, that is, the RSRP of antenna Ant1 after adjustment is small, so the antenna Ant1 is usually not scheduled. Similarly, referring to the strength attenuation values shown in Table 6, compared with the strength attenuation value of antenna Ant5, the strength attenuation value of antenna Ant4 is the largest, so the RSSI of antenna Ant4 after adjustment is the largest, so the RSRP of antenna Ant5 after adjustment is small, so the line Ant5 is usually scheduled.

It can be understood that the present application performs second antenna scheduling by comprehensively considering the received signal strength and antenna isolation of the second antenna to schedule the second antenna to work with the least actual interference. That is, the electronic device can schedule the second antenna in the wireless communication module 2 to work with better antenna isolation and a larger actual received signal strength value, so as to achieve the purpose of optimizing interference. For example, the second antenna scheduled by the electronic device can be the second antenna with the second highest antenna isolation among multiple second antennas.

In this way, when two wireless communication systems of an electronic device are in a coexistence scenario, the present application can configure different strength attenuation values for multiple antennas in each wireless communication module according to the coexistence scenario, and adjust the received signal strength according to the strength attenuation values of these antennas. Thereby, the received signal strength of the antennas with poor antenna isolation among the multiple antennas in the two wireless communication modules is reduced to the greatest extent, and the antennas with poor antenna isolation are avoided from being scheduled as much as possible. In this way, the influence of the transmission of the antenna of wireless communication module 1 on the reception of the antenna in wireless communication module 2 is weakened, that is, the coexistence interference between the two communication modules is reduced, and the communication quality of the two modules is improved.

Further, as shown in FIG9 , a schematic diagram of a flow chart of configuring the strength attenuation value of an antenna provided in an embodiment of the present application is provided. The execution subject in the flow shown in FIG9 is a server 200, which is specifically applied to a coexistence scenario 3 in which the wireless communication module 1 is a cellular network module and the wireless communication module 2 is a Wi-Fi module. The flow shown in FIG9 includes the following steps:

S901: The electronic device 100 initializes and obtains the coexistence frequency band, that is, initializes the coexistence frequency band and the strength attenuation values set for the corresponding two wireless communication modules.

S902: For a cellular network, based on the CELL cell change notification of CELL info, the electronic device 100 obtains channel information (ie, working frequency band).

S903: For Wi-Fi, the WLAN is connected to 2.4G or the Wi-Fi status changes, and the electronic device 100 obtains frequency information (ie, working frequency band).

S904: The electronic device 100 determines whether the frequency combination in the coexistence frequency band is satisfied, that is, whether the channel information of the cellular network and the frequency point information of the Wi-Fi network satisfy the frequency combination in the coexistence frequency band.

S905: The electronic device 100 configures the strength attenuation value of each antenna in the cellular network as a default strength attenuation value.

S906: The electronic device 100 configures the strength attenuation value of each antenna in the cellular network to be the strength attenuation value corresponding to the coexistence frequency band currently satisfied, such as the strength attenuation value corresponding to the coexistence frequency band 3 mentioned above.

Among them, the specific description of S901 to S906 can refer to the relevant description of S301-S306 in the example shown in Figure 3, which will not be repeated here. The process shown in Figure 7 mainly explains the process of adjusting the received signal strength of the antenna in the coexistence scenario 3 where the 2.4G frequency band of Wi-Fi and the N41 of the cellular network work simultaneously. Thus, the antenna with poor antenna isolation in the coexistence scenario 3 is avoided as much as possible.

Next, the communication method in the embodiment of the present application is described by the interaction of various modules in the electronic device 100.

10 is a schematic diagram of a structural framework of an electronic device provided in an embodiment of the present application. The electronic device 100 shown in FIG10 includes a wireless communication module 1 , a wireless communication module 2 , a coexistence service module 3 and a storage module 4 .

The wireless communication module 1 includes a plurality of first antennas 11 and a modem 12. The modem 12 can perform antenna scheduling on the plurality of first antennas 11 to select an antenna to work as RX or TX. For example, in the present application, the modem 12 can adjust the received signal strength values of the corresponding first antennas 11 according to the plurality of first strength attenuation values to perform antenna scheduling on the plurality of first antennas 12. In addition, the modem 12 can select or switch the working frequency band used by the wireless communication module 1.

The wireless communication module 2 includes one or more second antennas 21 and a modem 22. The modem 22 can perform antenna scheduling on the multiple second antennas 21 to select an antenna to work as RX or TX. In addition, the modem 22 can adjust the received signal strength value of the corresponding second antenna 22 according to the multiple second strength attenuation values to perform antenna scheduling on the multiple second antennas 22. In addition, in the present application, the modem 22 can select or switch the working frequency band used by the wireless communication module 2.

The storage module 4 is used to store the preset coexistence frequency bands, and the first strength attenuation values of the first antennas 11 in the wireless communication module 1 corresponding to the various coexistence frequency bands. In addition, in some embodiments, the storage module 4 is also used to store the second strength attenuation values of the second antennas 21 in the wireless communication module 2 corresponding to the various coexistence frequency bands.

The coexistence service module 3 is used to obtain the preset coexistence frequency band from the storage module 4, and determine whether the working frequency band of the wireless communication module 1 and the working frequency band of the wireless communication module 2 belong to any coexistence frequency band, so as to identify whether there is coexistence interference between the two wireless communication modules. Then, when it is identified that there is coexistence interference between the two wireless communication modules, the wireless communication module 1 can be triggered to send the corresponding strength attenuation values to the wireless communication module 1 and the wireless communication module 2.

Next, the communication method will be described based on each module in the electronic device 100 shown in FIG. 10 as an execution subject.

As shown in Figure 11, it is a flow chart of the communication method provided by the present application. Among them, the main difference between the method shown in Figure 11 and the method shown in Figure 3 is that the execution subject of Figure 3 is refined into each module in the electronic device 100 shown in Figure 10. In addition, the technical details shown in Figure 3 are still used in this process, and some of them will not be repeated here to avoid repetition.

Specifically, FIG11 shows that the method includes the following steps:

S1101: The coexistence server module 3 obtains the preset coexistence frequency bands and the multiple first strength attenuation values of the multiple first antennas 11 corresponding to each type of coexistence frequency band from the coexistence storage module 4. For example, the coexistence server module 3 obtains the preset coexistence frequency bands and the respective strength attenuation values when initialized.

S1102: The coexistence server module 3 obtains the working frequency band of the wireless communication module 1 from the Modem 12 in the wireless communication module 1. For example, the coexistence server module 3 sends a request to the Modem 12, and the Modem 12 returns the working frequency band of the wireless communication module 1 in response to the request.

S1103: The coexistence server module 3 obtains the working frequency band of the wireless communication module 2 from the Modem 22 in the wireless communication module 2. For example, the coexistence server module 3 sends a request to the Modem 22, and the Modem 22 returns the working frequency band of the wireless communication module 2 in response to the request.

S1104: The coexistence server module 3 determines whether the working frequency band of the wireless communication module 1 and the working frequency band of the wireless communication module 2 belong to a coexistence frequency band. If any coexistence frequency band is satisfied, the process proceeds to S1105. If none of the coexistence frequency bands is satisfied, the process proceeds to S1107.

S1105: Since the working frequency bands of the wireless communication module 1 and the wireless communication module 2 belong to the target coexistence frequency band, the coexistence server module 3 sends a plurality of first strength attenuation values corresponding to the plurality of first antennas 11 to the Modem 12. The plurality of first strength attenuation values correspond to the target coexistence frequency band.

S1106 : The modem 12 adjusts the received signal strength value of each first antenna 11 based on the first strength attenuation value corresponding to each first antenna 11 in the wireless communication module 1 to obtain an adjusted received signal strength value of each first antenna 11 .

S1107 : corresponding to the working frequency band of the wireless communication module 1 and the working frequency band of the wireless communication module 2 not satisfying any coexistence frequency band, the coexistence server module 3 sends the default strength attenuation value corresponding to each first antenna 11 to the Modem 12 .

S1108 : The modem 12 adjusts the received signal strength value of each first antenna 11 based on the default strength attenuation value corresponding to each first antenna 11 in the wireless communication module 1 to obtain an adjusted received signal strength value of each first antenna 11 .

S1109 : The modem 12 performs scheduling of the first antennas 11 based on the adjusted received signal strength values of the first antennas 11 in the wireless communication module 1 .

The detailed description of the above S1101 to S1109 can refer to the related description of S301 to S309 in FIG. 3 , which will not be repeated here.

In this way, the present application can perform scene recognition of two wireless communication modules through the coexistence service module 3 set up, and send corresponding multiple first strength attenuation values to one of the wireless communication modules 1. Therefore, the smaller the first strength attenuation value due to the poor antenna isolation of the first antenna 11, the smaller the adjusted receiving strength value. Therefore, the coexistence interference caused by the transmission of the first antenna 11 in the wireless communication module 1 to the second antenna 21 in the wireless communication module 2 is weakened, that is, the coexistence interference is optimized.

As shown in FIG12, it is a flow chart of a communication method provided by the present application. The difference between the method shown in FIG12 and the method shown in FIG11 is that the method in FIG12 replaces the branches S1107 to S1109 shown in FIG11 with S1201 and S1202. In addition, the technical details shown in FIG11 are still used in this process, and some are not repeated here to avoid repetition.

Specifically, FIG12 shows that the method includes the following steps:

S1101~S1106, and S1109, wherein S1101~S1106, and S1109 are the same as S1101~S1106, and S1109 shown in Figure 11, and will not be repeated here.

S1201: Corresponding to the fact that the working frequency band of the wireless communication module 1 and the working frequency band of the wireless communication module 2 do not belong to any coexistence frequency band, the coexistence service module 3 sends a default scheduling indication message to the Modem 12, where the default scheduling indication message is used to indicate that antenna scheduling is performed according to the signal reception strength value actually calculated by the antenna.

S1202: The modem 12 performs antenna scheduling according to the received signal strength values of each first antenna 11 in the wireless communication module 1. At this time, the received signal strength value of the first antenna 11 is the received signal strength value actually calculated by the modem 12.

The detailed description of the above S1201 and S1202 can refer to the related description of S310 in Figure 4, which will not be repeated here.

In this way, the present application instructs the wireless communication module 1 to perform antenna scheduling according to the default scheduling method through the coexistence service module 3 set up, that is, the process of the antenna's received signal strength is not triggered. The newly added code implementation for antenna scheduling based on the received signal strength after the antenna is adjusted in actual applications can be combined with the conventional code implementation for antenna scheduling based on the actual received signal strength of the antenna, thereby improving the applicability of the code.

As shown in Figure 13, it is a flow chart of the communication method provided by the present application. The difference between the method shown in Figure 12 and the method shown in Figure 11 is that the start-up mechanism defined by S1301 to S1303 may be included before S1101 or S1102 in Figure 13, and Figure 13 takes the example of including S1301 to S1303 before S1102 shown in Figure 11.

Specifically, FIG13 shows that the method includes the following steps:

S1101, wherein the S1101 is the same as the S1101 in FIG11 and will not be described again here.

S1301 : The modem 22 obtains the received signal strength value and SNR of each second antenna 21 .

S1302: Modem 22 determines whether the interference condition is met.

The interference condition may include: the received signal strength value of at least one second antenna in the wireless communication module 2 is less than the first threshold and the SNR is less than the second threshold. If yes, proceed to S1303, if not, continue to return to S1301 and continue to monitor the receiving state of the antenna in the current wireless communication module 2.

S1303: Modem 22 sends a startup message to coexistence service module 3, where the startup message is used to start coexistence service module 3. Starting coexistence service module 3 refers to triggering coexistence service module 3 to start coexistence scene recognition for two wireless communication modules in electronic device 100, and sending corresponding multiple first strength attenuation values to wireless communication module 1.

S1101~S1109, S1102~S1109 are the same as S1102~S1109 in Figure 11, and will not be repeated here.

Then, only when it is determined that the current wireless communication module 2 has a weak signal and is interfered with, operations such as coexistence scenario recognition and strength attenuation value configuration will be performed, which is beneficial to improving the execution efficiency of the antenna scheduling process in the communication method.

As shown in Figure 14, it is a flow chart of a communication method provided in an embodiment of the present application. As an example, the above S1102 and S1103 can be replaced by S1102a and S1103a respectively. For example, based on Figure 11, with reference to the method shown in Figure 14, the above S1102 and S1103 can be replaced by S1102a and S1103a respectively. Among them, the same steps and related descriptions of the method shown in Figure 14 and the method shown in Figure 11 will not be repeated hereinafter.

S1102a: When the state of the wireless communication module 1 changes, the coexistence service module 3 obtains the working frequency band of the wireless communication module 1 from the Modem 12 .

S1103a: When the state of the wireless communication module 2 changes, the coexistence service module 3 obtains the working frequency band of the wireless communication module 2 from the Modem 22. The description of S1102a and S1103a can refer to the related description of S302a and S303a in FIG6 , which will not be repeated here.

It can be understood that Modem 12 and Modem 22 can actively report the working frequency band to the coexistence service module 3, or return their respective working frequency bands at the request of the coexistence service module 3.

Then, when the state of at least one wireless communication module in the electronic device 100 changes, and the coexistence service module 3 determines that two wireless communication modules simultaneously fall into another coexistence frequency band of a different type, it is possible to re-acquire multiple strength attenuation values corresponding to the new type, which is beneficial to optimizing the coexistence interference between the two wireless communication modules.

As shown in FIG. 15 , a communication method is provided in an embodiment of the present application.

S1501: The coexistence server module 3 obtains from the coexistence storage module 4 a preset coexistence frequency band, and a plurality of first strength attenuation values corresponding to a plurality of first antennas and a plurality of second strength attenuation values corresponding to a plurality of second antennas for each type of coexistence frequency band.

S1502: The coexistence server module 3 obtains the working frequency band of the wireless communication module 1 from the Modem 12 in the wireless communication module 1. For example, the coexistence server module 3 sends a request to the Modem 12, and the Modem 12 returns the working frequency band of the wireless communication module 1 in response to the request.

S1503: The coexistence server module 3 obtains the working frequency band of the wireless communication module 2 from the Modem 22 in the wireless communication module 2. For example, the coexistence server module 3 sends a request to the Modem 22, and the Modem 22 returns the working frequency band of the wireless communication module 2 in response to the request.

S1504: The coexistence server module 3 determines whether the working frequency band of the wireless communication module 1 and the working frequency band of the wireless communication module 2 belong to a coexistence frequency band. If any coexistence frequency band is satisfied, the process proceeds to S1505. If none of the coexistence frequency bands is satisfied, the process proceeds to S1507.

S1505a: Since the working frequency bands of the wireless communication module 1 and the wireless communication module 2 belong to the target coexistence frequency band, the coexistence server module 3 sends a plurality of first strength attenuation values corresponding to the plurality of first antennas 11 to the Modem 12. The plurality of first strength attenuation values correspond to the target coexistence frequency band.

S1505b: Since the working frequency bands of the wireless communication module 1 and the wireless communication module 2 belong to the target coexistence frequency band, the coexistence server module 3 sends a plurality of second strength attenuation values corresponding to the plurality of second antennas 11 to the Modem 22. The plurality of second strength attenuation values correspond to the target coexistence frequency band.

S1506a: The modem 12 adjusts the received signal strength value of each first antenna 11 based on the first strength attenuation value corresponding to each first antenna 11 in the wireless communication module 1 to obtain an adjusted received signal strength value of each first antenna 11 .

S1506b: The modem 22 adjusts the received signal strength value of each second antenna 21 based on the second strength attenuation value corresponding to each second antenna 21 in the wireless communication module 2 to obtain an adjusted received signal strength value of each second antenna 21 .

S1507a: corresponding to the working frequency band of the wireless communication module 1 and the working frequency band of the wireless communication module 2 not satisfying any coexistence frequency band, the coexistence server module 3 sends the default strength attenuation value corresponding to each first antenna 11 to the Modem 12 .

S1507b: corresponding to the working frequency band of the wireless communication module 1 and the working frequency band of the wireless communication module 2 not satisfying any coexistence frequency band, the coexistence server module 3 sends the default strength attenuation value corresponding to each second antenna 21 to the Modem 22 .

S1508a: The modem 12 adjusts the received signal strength value of each first antenna 11 based on the default strength attenuation value corresponding to each first antenna 11 in the wireless communication module 1 to obtain an adjusted received signal strength value of each first antenna 11 .

S1508b: The modem 22 adjusts the received signal strength value of each second antenna 21 based on the default strength attenuation value corresponding to each second antenna 21 in the wireless communication module 2 to obtain an adjusted received signal strength value of each second antenna 21 .

S1509a: The modem 12 performs scheduling of the first antennas 11 based on the adjusted received signal strength values of the first antennas 21 in the wireless communication module 1 .

S1509 b: The modem 22 schedules the second antennas 21 based on the adjusted received signal strength values of the second antennas 21 in the wireless communication module 2 .

The detailed description of the above S1501 to S1509b can refer to the related description of S801 to S809 in Figure 8, which will not be repeated here.

In this way, when two wireless communication systems of an electronic device are in a coexistence scenario, the coexistence service module 3 can configure different strength attenuation values for multiple antennas in each wireless communication module according to the coexistence scenario, and adjust the received signal strength according to the strength attenuation values of these antennas. This reduces the impact of the transmission of the antenna of the wireless communication module 1 on the reception of the antenna in the wireless communication module 2, and improves the communication quality of the two modules.
