Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The application discloses electronic equipment and a communication control method, aims to solve the coordination problem of different types of antennas during working, and mainly takes a 5G/4G antenna and a Wi-Fi antenna as examples to describe the scheme of the application for convenience of description. The electronic apparatus and the communication control method of the present application will be described in detail below with specific embodiments.

Referring to fig. 1, a schematic structural diagram of an electronic device according to an alternative embodiment of the present application is provided, where the electronic device may be, but is not limited to, a mobile device such as a smart phone, a tablet computer, a personal digital assistant, and a vehicle-mounted terminal with a communication function, or a computer device such as a notebook, a kiosk, and a desktop with a communication function. As illustrated in fig. 1, the electronic device includes:

a first communication module 11 comprising at least one first communication submodule 111.

A second communication module 12 comprising at least one second communication sub-module 121, said second communication module 12 being different from said first communication module 11.

The first Communication module 11 and the second Communication module 12 included in the electronic device are different types of Communication modules, and may be any two of Communication modules such as but not limited to Wi-Fi, 3G/4G/5G, bluetooth, and NFC (Near Field Communication). It should be noted that, in the present application, a communication module or a communication sub-module refers to an antenna, which is a different expression of an antenna.

Taking the first communication module 11 as a Wi-Fi module and the second communication module 12 as a 5G module as an example, the first communication module 11 may include at least one Wi-Fi sub-module, the second communication module 12 may include at least one 5G sub-module, and each Wi-Fi sub-module or 5G sub-module may receive a data signal from a base station or other electronic equipment based on a corresponding communication manner, or transmit a data signal to the base station or other electronic equipment.

In an actual application scenario, since the 5G supports two uplinks to work simultaneously, and the Wi-Fi also supports two uplinks to work simultaneously, that is, for the application, two 5G sub-modules to transmit data signals simultaneously, and two Wi-Fi sub-modules to transmit data signals simultaneously are supported, in an actual application, when such a communication module is set on an electronic device, a plurality of sub-modules are usually set for each type of communication module, for example, 4 Wi-Fi sub-modules and 4 5G sub-modules are set on an electronic device such as a mobile phone or a notebook.

Preferably, the communication sub-modules in the first communication module 11 and the second communication module 12 may be relatively dispersedly disposed at different positions of the electronic device, so as to reduce the spatial energy (radiation energy) density of each sub-module when the CO-SAR phenomenon occurs by "the distance of the physical position" when each sub-module is disposed.

Referring to fig. 2, fig. 2 shows an exemplary diagram of two communication modules, namely Wi-Fi and 5G, provided in the electronic device, where the Wi-Fi communication module includes 4 Wi-Fi sub-modules, namely Wi-Fi 1a, Wi-Fi 2a, Wi-Fi 1b, and Wi-Fi 2b, the 5G communication module includes 4 5G sub-modules, namely

5G

1a,

5G

2a,

5G

1b, and 5G 2b, and each of the Wi-Fi sub-modules and the 5G sub-modules is respectively relatively dispersedly disposed at different positions of the electronic device.

The controller 13, in response to obtaining a detection message indicating that the first communication module 11 and the second communication module 12 need to operate simultaneously, performs the following operations:

controlling the first communication module 11 and the second communication module 12 to transmit data signals in a time-sharing manner;

or the like, or, alternatively,

and controlling at least one first communication submodule 111 in the first communication module 11 and at least one second communication submodule 121 in the second communication module 12 to transmit data signals, wherein the positions of the at least one first communication submodule 111 and the at least one second communication submodule 121 meet a specific condition.

The controller 13 may be, but is not limited to, an MCU (Microcontroller Unit) or an SOC (System on Chip) or other components that can be used to provide control functions.

When different types of communication modules (i.e., different types of antennas) operate simultaneously, a Co-SAR (common specific absorption rate) phenomenon occurs due to simultaneous transmission of data signals, so that a specific absorption rate is increased, and accordingly, a human body may be adversely affected or a product may not meet an SAR standard. For example, a 5G module and a Wi-Fi module are integrated on a notebook computer at the same time, the 5G module supports 4x4MIMO (Multiple-Input Multiple-Output), supports two uplinks to work at the same time, and the Wi-Fi module also supports two uplinks to work at the same time. In view of the above problem, the prior art solution generally uses a capacitive sensor to detect the approach of a human body, and reduces the power of each communication module when the approach of the human body is detected, and reduces the power of each communication module to avoid or alleviate the problem of specific absorption rate enhancement caused by Co-SAR.

In order to solve the problem and avoid adverse effects on the communication performance of the equipment system as much as possible, when the electronic equipment operates, the communication condition of the equipment system is detected, and when detection information which can be used for indicating that the equipment system needs to utilize the first communication module 11 and the second communication module 12 to work simultaneously is obtained, the controller 13 controls the first communication module 11 and the second communication module 12 to transmit data signals in a time-sharing mode, namely, the first communication module 11 and the second communication module 12 are controlled not to transmit data signals simultaneously; or, at least one first communication sub-module 111 and at least one second communication sub-module 121, the positions of which meet a specific condition, are selected from the first communication module 11 and the second communication module 12 to transmit data signals.

Specifically, for example, two 5G sub-modules in the 5G module and two Wi-Fi sub-modules in the Wi-Fi module are controlled to transmit data signals in a time-sharing manner (that is, when the two 5G sub-modules transmit data signals, the two Wi-Fi sub-modules do not transmit data signals, and conversely, when the two Wi-Fi sub-modules transmit data signals, the two 5G sub-modules do not transmit data signals), or two Wi-Fi sub-modules and two 5G sub-modules whose positions meet a specific condition are selected from the Wi-Fi module and the 5G module to transmit data signals, and the like.

The specific condition met by the position of the communication sub-module may be a condition that can be used to indicate that the layout position of each communication sub-module (or a part of the communication sub-modules in each communication sub-module) that needs to transmit a data signal is relatively far away in the electronic device, and for example, but not by way of limitation, the specific condition may specifically be: the distance between each communication sub-module needing to transmit data signals is greater than a set distance threshold, or the distance between at least part (e.g. two or three) of each communication sub-module needing to transmit data signals is greater than a set distance threshold, and so on.

According to the method, by detecting the communication condition of the equipment system and when obtaining detection information which can be used for indicating that the equipment system needs to utilize the simultaneous work of the first communication module 11 and the second communication module 12, the space energy (radiation energy) density of each communication sub-module during data transmission can be effectively reduced by performing the time-sharing control on the first communication module 11 and the second communication module 12 or performing the position-based communication control, so that the specific absorption rate of each communication sub-module during work is effectively reduced, and meanwhile, because the working parameters of each communication module during work (such as the transmission power of each communication module) are not changed, the communication performance of the equipment system cannot be adversely affected.

Here, it should be noted that, when the link of the communication module receives the data signal, the antenna does not radiate energy outwards, and there is no SAR problem, so that when the first communication module 11 and the second communication module 12 receive the data signal simultaneously, there is no CO-SAR phenomenon, and there is no problem that the health of the human body is damaged or the device product cannot meet the SAR standard due to CO-SAR, when it is detected that the device system only needs to receive the data signal by using the first communication module 11 and the second communication module 12 simultaneously (i.e. there is no data transmission requirement for both communication modules), there is no need to perform the above-mentioned communication intervention on the communication module of the electronic device, and in addition, when it is detected that only one communication module needs to be used to transmit the data signal, for example, it is detected that only two uplinks (corresponding to two Wi-Fi sub-modules) in the Wi-Fi module need to transmit the data signal, the 5G module needs to receive data signals or does not work, and in this case, although the CO-SAR phenomenon is generated by the communication module due to the simultaneous transmission of data signals by two uplinks, however, the specific absorption rate generated by the CO-SAR phenomenon under the condition is in accordance with the SAR standard required by electronic equipment products, and the human health is not affected by the verification, therefore, in this case, the communication intervention on the communication module is not needed, but only on the condition that the data signals are transmitted by the first communication module and the second communication module at the same time, so as to reduce the spatial energy (radiation energy) density when each communication module transmits data signals by time-sharing control or position-based communication control.

The electronic device provided in this embodiment includes a first communication module 11, a second communication module 12, and a controller 13, where the first communication module 11 includes at least one first communication submodule 111, and the second communication module 12 includes at least one second communication submodule 121. With the solution of this embodiment, when the first communication module 11 and the second communication module 12 need to operate simultaneously (for example, need to transmit data signals simultaneously), the controller 13 may control the first communication module 11 and the second communication module 12 to transmit data signals in a time-sharing manner; or, at least one first communication sub-module 111 and at least one second communication sub-module 121, which are located in the two communication modules and meet a specific condition, are controlled to transmit data signals. By controlling the two communication modules to transmit data signals in a time-sharing manner or controlling the corresponding communication sub-modules in the two communication modules, the positions of which accord with specific conditions, to transmit data signals, the problem that the specific absorption rate of the two communication modules is enhanced due to the simultaneous working can be effectively solved, so that the problems that the human body is injured and the product cannot reach the SAR standard are avoided, and meanwhile, the working parameters of the communication modules are not adjusted, so that the communication performance of the system cannot be adversely affected.

In an optional embodiment of the electronic device described in the present application, the detection information may include, but is not limited to: the device system calls information of each communication submodule in a data transmitting state or a data receiving state in the first communication submodule 11 and the second communication submodule 12.

Specifically, when the device system needs to transmit data signals or receive data signals based on one or more communication modes based on its actual data communication requirements (e.g. an application with a communication function installed in the device or a communication function provided by the device system itself needs to transmit and receive data), the corresponding communication sub-module in the data sending state or the data receiving state in the corresponding kind of communication module (such as Wi-Fi or 5G, etc.) is called to complete the required data sending task or data receiving task, and based on the characteristic, in specific implementation of the present application, the call information of each communication sub-module in the first communication module 11 or the second communication module 12 in the data transmitting state or the data receiving state may be detected, and the communication requirement of the device system is obtained by detecting the call information.

Specifically, for example, by detecting the call information, it is known that the device system specifically needs to transmit a data signal by using the first communication module 11 and the first communication module 12 at the same time, or needs to receive a data signal by using the first communication module 11 and the first communication module 12 at the same time, or needs to transmit a data signal by using one of the first communication module 11 and the first communication module 12, or needs to receive a data signal by using another one of the first communication module 11 and the second communication module 12, or needs to transmit a data signal (and/or receive a data signal) by using one of the first communication module 11 and the second communication module 12, or does not work by using the other one.

Wherein, when it is known that the device system specifically needs to transmit data signals simultaneously by using the first communication module 11 and the second communication module 12 by detecting the call information, that is, when obtaining a detection information that can be used to indicate that the first communication module 11 and the second communication module 12 need to transmit data signals simultaneously, the controller 13 may be triggered to respond to the detection information that can be used to indicate that the first communication module 11 and the second communication module 12 need to transmit data signals simultaneously, and perform the time-sharing control or the location-based communication control on the first communication module 11 and the second communication module 12, so as to reduce the spatial energy (radiation energy) density when each communication module transmits data signals, thereby alleviating the problem of specific absorption rate enhancement caused by the simultaneous operation of the two communication modules, meanwhile, the working parameters of each communication module in working are not changed (for example, the data signal transmitting power of each communication module is not reduced), so that the communication performance of the equipment system is not adversely affected.

In an optional embodiment of the electronic device of the present application, the controlling the first communication module 11 and the second communication module 12 by the controller 13 to transmit the data signal in a time-sharing manner includes:

controlling at least one first communication submodule 111 in the first communication module 11 and at least one second communication submodule 121 in the second communication module 12 to be in a data transmission state, and transmitting data signals in a time-sharing manner;

alternatively, the first and second electrodes may be,

controlling at least one first communication submodule 111 in the first communication module 11 to be in a data receiving state, and controlling at least one second communication submodule 121 in the second communication module 12 to be in a data transmitting state; or, at least one first communication sub-module 111 in the first communication module 11 is controlled to be in a data transmission state, and at least one second communication sub-module 121 in the second communication module 12 is controlled to be in a data reception state.

Specifically, when the controller 13 controls the first communication module 11 and the second communication module 12 to transmit data signals in a time-sharing manner, as a possible implementation manner, each first communication sub-module 111 of the first communication module 11 that needs to transmit data signals and each second communication sub-module 121 of the second communication module 12 that needs to transmit data signals can be controlled to be in a data transmission state, and each first communication sub-module 111 of the first communication module 11 that needs to transmit data signals and each second communication sub-module 121 of the second communication module 12 that needs to transmit data signals are controlled in a time-sharing manner to transmit data signals in a time-sharing manner, for example, two Wi-Fi sub-modules of a Wi-Fi module and two 5G sub-modules of a 5G module are controlled to be in a data transmission state, and the two Wi-Fi sub-modules and the two 5G sub-modules are controlled in a time-sharing manner to transmit data signals, therefore, only one communication module transmits data signals at each specific moment, and the space energy (radiation energy) density of the equipment is effectively reduced.

As another possible implementation manner, each first communication sub-module 111 that needs to transmit a data signal in the first communication module 11 and each second communication sub-module 121 that needs to transmit a data signal in the second communication module 12 may be further controlled to be in a data transmission state, and one type of communication sub-module is controlled to be in a data reception state, for example, specifically, for a 5G module and a Wi-Fi module that need to simultaneously transmit a data signal by using two uplinks, two 5G sub-modules corresponding to two uplinks in the 5G module may be maintained in the data transmission state, and two Wi-Fi sub-modules corresponding to two uplinks in the Wi-Fi module may be switched from the data transmission state to the data reception state, so that, at each specific time, and only one communication module transmits data signals, so that the space energy (radiation energy) density of the equipment is effectively reduced.

For a communication submodule working based on a Time Division Duplex (TDD) characteristic, the same frequency band is adopted for transmitting and receiving data signals, so that in specific implementation, switching of data signal transmitting and receiving states can be directly performed on the communication submodule based on actual requirements, and as a data transmitting link and a data receiving link of the communication submodule adopt the same frequency band, switching in the aspect of communication frequency bands does not exist; in addition, for a communication sub-module operating based on Frequency Division Duplex (FDD) characteristics, different Frequency bands are respectively used for transmitting and receiving data signals, so that in a specific implementation, when switching between data signal transmitting and receiving states is performed based on actual requirements, switching of a communication Frequency band is also involved in addition to switching of a data communication link of the communication sub-module, for example, switching of a certain 5G sub-module from a data transmitting link to a data receiving link and the like.

Taking the first communication module as a Wi-Fi module and the second communication module as a 5G module as an example, the Wi-Fi module supports a time division duplex characteristic, and the 5G module supports both the time division duplex characteristic and the frequency division duplex characteristic, so that, for the Wi-Fi module, when switching the data transmission/reception state thereof, switching of the communication frequency band is not involved, and for the 5G module, if the 5G module operates based on the time division duplex characteristic, when switching the data transmission/reception state thereof, switching of the communication frequency band is not involved; if the 5G module operates based on the frequency division duplex characteristic, the switching of the communication frequency band may be involved when the data transmission/reception state is switched.

In an optional embodiment of the electronic device according to the present application, the controlling unit 13 controls at least one first communication submodule 111 in the first communication module 11 and at least one second communication submodule 121 in the second communication module 12 (where a position of the at least one first communication submodule 111 and the at least one second communication submodule 121 meets a specific condition) to transmit a data signal, specifically including:

and controlling at least one first communication submodule 111 in the first communication module 11 and at least one second communication submodule 121 in the second communication module 12 to transmit data signals simultaneously or in a time-sharing manner.

Specifically, when the at least one first communication sub-module 111 and the at least one second communication sub-module 121 whose positions meet the specific condition are controlled to transmit data signals, as a possible implementation manner, the at least one first communication sub-module 111 and the at least one second communication sub-module 121 whose positions meet the specific condition may be controlled to transmit data signals simultaneously, for example, two Wi-Fi sub-modules and two 5G sub-modules whose positions meet the specific condition are controlled to transmit data signals simultaneously, and the like. As described above, the specific condition is a condition that can be used to indicate that the layout position of each communication submodule (or a part of the communication submodules) which needs to transmit data signals in the electronic device is relatively far away, so that, in this implementation, even if the at least one first communication submodule 111 and the at least one second communication submodule 121 transmit data signals simultaneously, since the layout positions of the at least one first communication submodule 111 and the at least one second communication submodule 121 in the electronic device are relatively far away, the effect of effectively reducing the spatial energy (radiation energy) density when each communication submodule transmits data can be achieved.

As another possible implementation manner, the at least one first communication submodule 111 and the at least one second communication submodule 121, the positions of which meet a specific condition, may also be controlled to transmit data signals in a time-sharing manner, and the implementation manner of transmitting data signals in a time-sharing manner may include two types: 1) the at least one first communication submodule 111 and the at least one second communication submodule 121 are both controlled to be in a data transmission state, and the at least one first communication submodule 111 and the at least one second communication submodule 121 are controlled to transmit data signals in a time-sharing mode in a time-sharing control mode; 2) one type of the at least one first communication sub-module 111 and the at least one second communication sub-module 121 is controlled to be in a data transmitting state, and the other type of the communication sub-module is controlled to be in a data receiving state, so that only one type of communication module transmits data signals at each specific moment, and the spatial energy (radiation energy) density of the device is effectively reduced.

The specific implementation processes of the 1 st mode and the 2 nd mode) may specifically refer to the above statements, and are not described herein again.

In this embodiment, by performing the time-sharing control or the location-based communication control on the first communication module 11 and the second communication module 12, the spatial energy (radiation energy) density of each communication sub-module during data transmission can be effectively reduced, so that the specific absorption rate of the first communication module 11 and the second communication module 12 during simultaneous operation is effectively reduced, and meanwhile, since the working parameters of each communication module during operation are not changed (for example, the data signal transmission power of each communication module is not reduced), the communication performance of the device system is not adversely affected.

In an optional embodiment of the electronic device of the present application, the controller 13, in response to the detection information that can be used to indicate that the first communication module 11 and the second communication module 12 need to operate simultaneously, may further be configured to:

determining a first priority of the first communication module 11 for transmitting data signals, and determining a second priority of the second communication module 12 for transmitting data signals;

and triggering a matched communication mode to perform communication control on the first communication module 11 and the second communication module 12 based on the first priority and the second priority.

When it is known that the device system needs to transmit data signals simultaneously by using the first communication module 11 and the second communication module 12 by detecting the call information of the device system to the first communication module 11 and the second communication module 12, that is, when obtaining a detection information that can indicate that the first communication module 11 and the second communication module 12 need to work simultaneously, the communication control of the first communication module 11 and the second communication module 12 may be triggered by considering the priority of the first priority of the data signals transmitted by the first communication module 11 and the priority of the second priority of the data signals transmitted by the second communication module 12.

In specific implementation, the first priority of the data signal transmitted by the first communication module 11 and the second priority of the data signal transmitted by the second communication module 12 may be determined according to the priority of the service type of the data to be transmitted of the first communication module 11 and the second communication module 12, and/or the priority of the first communication module 11 and the priority of the second communication module 12.

For example, it is assumed that at present, two 5G sub-modules in a 5G module need to be used to transmit an instant message of an instant messaging service, and at the same time, two Wi-Fi sub-modules in a Wi-Fi module need to be used to transmit download data corresponding to the download service (for example, a mobile phone serving as a Wi-Fi hotspot transmits movie data to another mobile phone, so that a movie episode is downloaded on another mobile phone, etc.), and considering that the real-time requirement of the instant messaging service is higher than that of the download service, a priority level of the instant message transmitted by the 5G module may be set higher than a priority level of the download data transmitted by the Wi-Fi module; as another possible implementation manner, if the system defaults or the user sets the priority of the different communication modules, for example, assuming that the priority of the Wi-Fi module is set to be higher than that of the 5G module, the priority of the different communication modules when transmitting data signals can be determined according to the system setting condition; in addition, the priority levels of the service types of the data to be transmitted of the first communication module 11 and the second communication module 12 and the priority levels of the first communication module 11 and the second communication module 12 themselves may be integrated by adopting a weighted calculation manner to calculate the first priority level of the data signal transmitted by the first communication module 11 and the second priority level of the data signal transmitted by the second communication module 12.

After determining the first priority of the data signal transmitted by the first communication module 11 and the second priority of the data signal transmitted by the second communication module 12, the following communication control may be performed on the first communication module 11 and the second communication module 12 based on the first priority and the second priority:

1) if the first priority is equal to the second priority, triggering execution: controlling at least one first communication submodule 111 and at least one second communication submodule 121, the positions of which meet a specific condition, in the first communication module 11 and the second communication module 12 to simultaneously transmit data signals; or, at least one first communication submodule 111 and at least one second communication submodule 121 in the first communication module 11 and the second communication module 12 are controlled to transmit the data signals in a time-sharing manner;

in this application, the first communication module 11 has a time division duplex characteristic, for example, specifically, a Wi-Fi module having the time division duplex characteristic, and the second communication module 12 has a time division duplex characteristic and a frequency division duplex characteristic, for example, specifically, a 5G module having the time division duplex characteristic and the frequency division duplex characteristic, and of course, in an alternative specific implementation, the first communication module 11 may also have the time division duplex characteristic and the frequency division duplex characteristic, and the second communication module 12 may also have the time division duplex characteristic, which is not limited in this embodiment.

Taking the first communication module 11 having the tdd characteristic and the second communication module 12 having the tdd characteristic as an example, in case that the first priority is equal to the second priority, the controller 13 is further configured to:

if the second communication module 12 operates based on the frequency division duplex characteristic, the following is triggered to be executed: controlling at least one first communication submodule 111 and at least one second communication submodule 121, the positions of which meet a specific condition, in the first communication module 11 and the second communication module 12 to simultaneously transmit data signals;

if the second communication module 12 operates based on the time division duplex characteristic, the following is triggered to be executed: controlling at least one first communication submodule 111 and at least one second communication submodule 121, the positions of which meet a specific condition, in the first communication module 11 and the second communication module 12 to simultaneously transmit data signals; or, at least one first communication submodule 111 in the first communication module 11 and at least one second communication submodule 121 in the second communication module 12 are controlled to transmit the data signal in a time-sharing manner.

For example, assuming that the first communication module 11 is a Wi-Fi module and operates based on a time division duplex characteristic, and the second communication module 12 is a 5G module and also operates based on a time division duplex characteristic, when the Wi-Fi module and the 5G module transmit data signals at the same time, the two Wi-Fi sub-modules and the two 5G sub-modules in the Wi-Fi module and the 5G module, which are located at specific conditions, may be controlled to transmit data signals at the same time, in this manner, although the two Wi-Fi sub-modules and the two 5G sub-modules transmit data signals at the same time, since the two Wi-Fi sub-modules and the two 5G sub-modules are located at relatively far positions in the electronic device (which corresponds to the specific condition that the representative positions are located at far distances), the space energy (radiation energy) density of each communication sub-module during data transmission may be effectively reduced The effect is achieved; or, two Wi-Fi sub-modules in the Wi-Fi module and two 5G sub-modules in the 5G module may be selected, and the two selected Wi-Fi sub-modules and the two 5G sub-modules are controlled to transmit data signals in a time division manner, in which only one communication module transmits data signals at each specific time, so that the spatial energy (radiation energy) density of the device is effectively reduced.

And under the condition that the 5G module works based on the frequency division duplex characteristic, the two Wi-Fi sub-modules in the Wi-Fi module and the two 5G sub-modules in the 5G module need to be subjected to communication control by adopting a position-based simultaneous data transmission mode.

2) If the first priority is lower than the second priority, triggering to execute: controlling at least one second communication submodule 121 in the second communication module 12 to be in a data transmitting state and at least one first communication submodule 111 in the first communication module 11 to be in a data receiving state, until a first condition is met, controlling the at least one first communication submodule 111 to be in the data transmitting state;

the first condition may be, but is not limited to: the duration that each second communication submodule 121 is in a data transmitting state and each first communication submodule 111 is in a data receiving state reaches a set duration, for example, 6s, 10s, and the like; or, each second communication sub-module has completed the current data transmission task (suitable for the case that the amount of data signals currently required to be transmitted by each second communication sub-module 121 is small), and so on.

In this way, each first communication sub-module 111 with low priority of transmitting data signals is controlled to be in a data receiving state, so that the data signal transmitting requirement of each second communication sub-module 121 with high priority of transmitting data signals can be met preferentially; when the first condition is met, the first communication sub-modules 111 are controlled to be in a data transmission state, which aims to further effectively meet the requirement (although the priority is low, the requirement still exists) that the first communication sub-modules 111 transmit data signals.

After each first communication sub-module 111 is switched back to the data transmission state from the data receiving state, the present embodiment does not limit the communication manner between each first communication sub-module 111 switched back to the data transmission state and each second communication sub-module 121 in the data transmission state, for example, each second communication sub-module 121 in the data transmission state and each first communication sub-module 111 in the data transmission state may be controlled in a time-division control manner to transmit data in a time-division manner, or when the positions of each second communication sub-module 121 in the data transmission state and each first communication sub-module 111 in the data transmission state satisfy the above specific condition, the two types of modules may also be controlled to transmit data signals simultaneously; or, each second communication sub-module 121 may have completed its current data transmission task, so that only the first communication sub-module 111 is controlled to transmit the data signal.

3) If the first priority is higher than the second priority, triggering to execute: at least one first communication submodule 111 in the first communication module 11 is controlled to be in a data transmitting state, and at least one second communication submodule 121 in the second communication module 12 is controlled to be in a data receiving state, until a second condition is met, the at least one second communication submodule 121 is controlled to be in the data transmitting state.

The second condition may be, but is not limited to: the duration that each first communication submodule 111 is in a data transmitting state and each second communication submodule 121 is in a data receiving state reaches a set duration, for example, 6s, 10s, and the like; or, each first communication sub-module 111 completes the current data transmission task (suitable for the case that the amount of data signals to be transmitted currently by each first communication sub-module 111 is small), and so on.

In this way, by controlling each second communication sub-module 121 with a low priority for transmitting data signals to be in a data receiving state, the data signal transmission requirements of each first communication sub-module 111 with a high priority for transmitting data signals can be met preferentially; the respective second communication sub-modules 121 are controlled to be in the data transmission state when the second condition is met, which aims to further effectively satisfy the requirement (although the priority is low, the requirement still exists) that the respective second communication sub-modules 121 transmit the data signals.

After each second communication sub-module 121 is switched back to the data transmission state from the data receiving state, the present embodiment also does not limit the communication manner between each second communication sub-module 121 switched back to the data transmission state and each first communication sub-module 111 in the data transmission state, for example, each second communication sub-module 121 in the data transmission state and each first communication sub-module 111 in the data transmission state may be controlled in a time-division control manner to transmit data in a time-division manner, or when the positions of each second communication sub-module 121 in the data transmission state and each first communication sub-module 111 in the data transmission state satisfy the above specific conditions, the two types of modules may also be controlled to transmit data signals simultaneously; or, each first communication sub-module 111 may have completed its current data transmission task, so as to only control the second communication sub-module 121 to transmit the data signal.

In this embodiment, a first priority of the first communication module 11 for transmitting the data signal and a second priority of the second communication module 12 for transmitting the data signal are considered in combination to trigger a matched communication mode to perform communication control on the first communication module 11 and the second communication module 12, so that the signal transmission efficiency of high-priority data or communication modules is effectively ensured.

In an optional embodiment of the electronic device in the present application, referring to the schematic structural diagram of the electronic device shown in fig. 3, the electronic device may further include:

a first data transmission link 112, a first data receiving link 113 corresponding to the first communication submodule 111;

a second data transmission link 122 and a second data reception link 123 corresponding to the second communication submodule 121;

at least one first switch 14, each first switch 14 is connected between a corresponding first communication submodule 111 and a first data transmission link 112 and a first data receiving link 113 corresponding to the first communication submodule 111, and each first switch 14 is connected with the controller 13;

at least one second switch 15, each second switch 15 is connected between a corresponding second communication submodule 121 and a second data transmission link 122 and a second data receiving link 123 corresponding to the second communication submodule 121, and each second switch 15 is connected with the controller 13;

the controller 13 controls the first switch 14 to control the first communication submodule 111 to be connected with the corresponding first data transmission link 112 or first data receiving link 113, so as to control the first communication submodule 111 to be in a data transmission state or a data receiving state;

the controller 13 controls the second switch 15 to control the second communication submodule 121 to be connected with the corresponding second data transmission link 122 or second data receiving link 123, so as to control the second communication submodule 121 to be in a data transmission state or a data receiving state.

The first data transmission link 112 of the first communication sub-module 111 and the second data transmission link 122 of the second communication sub-module 121 may include, but are not limited to, a Power Amplifier (PA); the first data receiving link 113 of the first communication sub-module 111 and the second data receiving link 123 of the second communication sub-module 121 may include, but are not limited to, a Low Noise Amplifier (LNA).

The first switch 14 and the second switch 15 may be single-pole double-throw or double-pole double-throw rf switches, and the number of the first switch 14 and the second switch 15 may be 1 or more respectively, and in practical application, may be selected according to circuit design requirements.

With the first communication module 11 being a Wi-Fi module (supporting time division duplex) and the second communication module 12 being a 5G module (supporting time division duplex and frequency division duplex), referring to fig. 4, fig. 4 provides an exemplary diagram of a control circuit for controlling communication between the Wi-Fi module and the 5G module when the 5G module operates based on a Time Division Duplex (TDD) characteristic.

In this example, the Wi-Fi module comprises 4 Wi-Fi sub-modules of Wi-Fi 1a, Wi-Fi 2a, Wi-Fi 1b and Wi-Fi 2b, and the 5G module comprises 4 5G sub-modules of

5G

1a,

5G

2a,

5G

1b and 5G 2 b. The Wi-Fi 1a and the Wi-Fi 1b are connected with a Wi-Fi data sending link (Wi-Fi Tx) and a Wi-Fi Rx) through two single-pole double-throw radio frequency switches, the two single-pole double-throw radio frequency switches are respectively connected with a controller (Space-time manager), and in a specific application process, the controller can control the two single-pole double-throw radio frequency switches according to actual requirements to select between the Wi-Fi 1a and the Wi-Fi 1b and switch link states between the Wi-Fi Tx and the Wi-Fi Rx. The

5G

1a and 5G 1b are connected with a 5G data transmission link (5G Tx) and a 5G data receiving link (5G Prx) through a single-pole double-throw and a double-pole double-throw radio frequency switch, the double-pole double-throw radio frequency switch is connected with the data receiving link (5G MIMO1), and the single-pole double-throw and the double-pole double-throw radio frequency switch are respectively connected with a controller (Space-time manager).

It should be noted that, in this example, circuit connection information of Wi-Fi 2a, Wi-

Fi

2b,

5G

2a, and 5G 2b is not given, where circuit connection conditions of Wi-Fi 2a and Wi-Fi 2b are similar to those of Wi-Fi 1a and Wi-Fi 1b, and circuit connection thereof may be achieved through another set of switch components and data receiving and transmitting links that are the same as those of Wi-Fi 1a and Wi-Fi 1b, and circuit connection conditions of

5G

2a and 5G 2b are similar to those of

5G

1a and 5G 1b, and circuit connection thereof may be achieved through another set of switch components and data receiving and transmitting links that are the same as those of

5G

1a and 5G 1b, and will not be shown in detail here.

For the control circuit example diagram shown in fig. 4, when the calling information of the communication module is detected by the device system and it is known that two Wi-Fi sub-modules and two 5G sub-modules need to be used to transmit data signals at the same time, two Wi-Fi sub-modules and two 5G sub-modules whose positions meet specific conditions may be selected to transmit data signals at the same time, for example, Wi-Fi 1a, Wi-

Fi

2a,

5G

1a, and 5G 2b whose position layouts are relatively far are selected to transmit data signals at the same time; or, under the condition of not considering the layout position of each communication sub-module, the two Wi-Fi sub-modules and the two 5G sub-modules can transmit data in a time division mode, or one type of the two communication sub-modules is controlled to be in a data receiving state through a switch, and the other type of the two communication sub-modules is controlled to be in a data transmitting state, so that only one type of communication module transmits data at the same time.

Of course, the matching communication control mode can also be selected by combining the priority ratio of the first priority of the Wi-Fi module for transmitting the data signal and the second priority of the 5G module for transmitting the data, and the communication control mode after the priority can be referred to the above description specifically, and detailed description is not repeated here. For the situations that one type of communication module in Wi-Fi and 5G needs to be used for transmitting data signals, the other type of communication module needs to be used for receiving data signals or does not work, and the situations that the two types of communication modules need to be used for receiving data signals simultaneously, the phenomenon of CO-SAR which causes harm to human health or causes products to fail to reach SAR standards does not occur, so that communication intervention on each communication module is not needed.

Referring to fig. 5, fig. 5 is a diagram of an example of a control circuit for controlling communication between the Wi-Fi module and the 5G module when the 5G module operates based on a Frequency Division Duplex (FDD) characteristic. The communication control circuit of the 5G module based on the working condition of frequency division duplex characteristic is similar to the communication control circuit of the 5G module based on the working condition of time division duplex characteristic, and the difference is that the 5G 1a and the 5G 1b are connected with a duplexer and a data transmitting link (5G Tx) and a data receiving link (5G Prx) of the 5G through a double-pole double-throw switch, and the duplexer is used for isolating a transmitting signal from a receiving signal so as to ensure that the receiving and the transmitting can work normally at the same time. In specific work, the 5G in the case of frequency division duplex no longer supports time division control based on a time division control mode. The operation principle of other aspects is similar to that of the circuit diagram in fig. 4, and the two communication modules can perform required communication intervention according to the specific communication requirements of the two communication modules, namely Wi-Fi and 5G, or also in combination with the communication priority of the two communication modules, and therefore, the detailed description is omitted here.

Corresponding to the electronic equipment, the application also discloses a communication control method applicable to the electronic equipment, the electronic equipment comprises a first communication module and a second communication module, the first communication module comprises at least one first communication sub-module, the second communication module comprises at least one second communication sub-module, and the second communication module is different from the first communication module; for more detailed components and features of each component of the electronic device to which the communication control method is applied, the above description is specifically referred to, and detailed descriptions thereof are omitted here.

Referring to a flowchart of a communication control method illustrated in fig. 6, the method may include:

step 601, obtaining detection information which can be used for indicating that the first communication module and the second communication module need to work simultaneously.

In response to obtaining the detection information that can be used to indicate that the first communication module and the second communication module need to work simultaneously, performing the following operations:

step 602, controlling the first communication module and the second communication module to transmit data signals in a time-sharing manner;

or the like, or, alternatively,

step 603, controlling at least one first communication submodule in the first communication module and at least one second communication submodule in the second communication module to transmit data signals, wherein the positions of the at least one first communication submodule and the at least one second communication submodule meet specific conditions.

Taking the first communication module as a Wi-Fi module and the second communication module as a 5G module as an example, when the 5G module transmits data signals on both its uplinks and at the same time the Wi-Fi module also transmits data signals on both its uplinks, specifically, for example, under the scene that the 5G module of the electronic equipment is in an opening state and the electronic equipment simultaneously opens the Wi-Fi hot spot function (namely the electronic equipment serves as a Wi-Fi transceiver to provide the Wi-Fi hot spot function for the peripheral electronic equipment), when both the Wi-Fi module and the 5G module transmit data signals through both of their uplinks, a Co-SAR phenomenon occurs, this in turn leads to problems with increased specific absorption rate, which in turn may have an adverse effect on the human body or may also lead to products that do not meet SAR standards.

In order to solve the problem and avoid adverse effects on the communication performance of the equipment system as far as possible, when the electronic equipment operates, the communication condition of the equipment system is detected, and when detection information which can be used for indicating that the equipment system needs to utilize the simultaneous work of the first communication module and the second communication module is obtained, the first communication module and the second communication module are controlled to transmit data signals in a time-sharing mode, namely, the first communication module and the second communication module are controlled not to transmit data signals simultaneously; or selecting at least one first communication sub-module and at least one second communication sub-module with the positions meeting specific conditions from the first communication module and the second communication module to transmit data signals.

According to the method, the communication condition of the equipment system is detected, when detection information which can be used for indicating that the equipment system needs to utilize the simultaneous working of the first communication module and the second communication module is obtained, the time-sharing control is carried out on the first communication module and the second communication module or the position-based communication control is carried out, so that the space energy (radiation energy) density of each communication sub-module during data transmission is effectively reduced, the specific absorption rate of the first communication module and the second communication module during working is effectively reduced, and meanwhile, because the working parameters of each communication module during working are not changed (for example, the transmission power of each communication module is not reduced), the communication performance of the equipment system is not adversely affected.

Here, it should be noted that, when the link of the communication module receives the data signal, the antenna does not radiate energy outwards, and there is no SAR problem, so that when the first communication module and the second communication module receive the data signal simultaneously, there is no CO-SAR phenomenon, and there is no problem that the health of the human body is damaged or the equipment product cannot meet the SAR standard due to CO-SAR, therefore, when it is detected that the equipment system only needs to receive the data signal by using the first communication module and the second communication module simultaneously (i.e. there is no data transmission requirement for both communication modules), the communication intervention on the communication module of the electronic equipment is not needed, and in addition, when it is detected that only one communication module needs to be used to transmit the data signal, for example, it is detected that only two uplinks (corresponding to two Wi-Fi sub-modules) in the Wi-Fi module need to transmit the data signal, the 5G module needs to receive data signals or does not work, and in this case, although the CO-SAR phenomenon is generated by the communication module due to the simultaneous transmission of data signals by two uplinks, however, the specific absorption rate generated by the CO-SAR phenomenon under the condition is in accordance with the SAR standard required by electronic equipment products, and the human health is not affected by the verification, therefore, in this case, the communication intervention on the communication module is not needed, but only on the condition that the data signals are transmitted by the first communication module and the second communication module at the same time, so as to reduce the spatial energy (radiation energy) density when each communication module transmits data signals by time-sharing control or position-based communication control.

With the scheme of this embodiment, when the first communication module and the second communication module need to operate simultaneously (for example, need to transmit data signals simultaneously), the controller may control the first communication module and the second communication module to transmit data signals in a time-sharing manner; or, at least one first communication sub-module and at least one second communication sub-module which are positioned in the two communication modules and meet the specific condition are controlled to transmit data signals. By controlling the two communication modules to transmit data signals in a time-sharing manner or controlling the corresponding communication sub-modules in the two communication modules, the positions of which accord with specific conditions, to transmit data signals, the problem that the specific absorption rate of the two communication modules is enhanced due to the simultaneous working can be effectively solved, so that the problems that the human body is injured and the product cannot reach the SAR standard are avoided, and meanwhile, the working parameters of the communication modules are not adjusted, so that the communication performance of the system cannot be adversely affected.

In an optional embodiment of the communication control method of the present application, the detection information may include, but is not limited to: the device system calls the information of each communication submodule in a data transmitting state or a data receiving state in the first communication submodule and the second communication submodule.

Specifically, when the device system needs to transmit data signals or receive data signals based on one or more communication modes based on its actual data communication requirements (e.g. an application with a communication function installed in the device or a communication function provided by the device system itself needs to transmit and receive data), the corresponding communication sub-module in the data sending state or the data receiving state in the corresponding kind of communication module (such as Wi-Fi or 5G, etc.) is called to complete the required data sending task or data receiving task, and based on the characteristic, in specific implementation of the present application, the call information of the device system to each communication sub-module in the first communication module or the second module in the data transmitting state or the data receiving state may be detected, and the communication requirement of the device system may be obtained by detecting the call information.

Specifically, for example, by detecting the call information, it is known that the device system specifically needs to transmit a data signal by using the first communication module and the first communication module at the same time, or needs to receive a data signal by using the first communication module and the first communication module at the same time, or needs to transmit a data signal by using one of the first communication module and receive a data signal by using the other one of the first communication module and the second communication module, or does not operate the other one of the first communication module and the second communication module.

When it is known that the device system specifically needs to transmit data signals simultaneously by using the first communication module and the second communication module by detecting the call information, that is, when obtaining detection information that can indicate that the first communication module and the second communication module need to transmit data signals simultaneously, the device system may respond to the detection information that can indicate that the first communication module and the second communication module need to transmit data signals simultaneously, and perform the time-sharing control or the location-based communication control on the first communication module and the second communication module, so as to reduce the spatial energy (radiation energy) density when the communication modules transmit data signals, thereby alleviating the problem of specific absorption rate enhancement caused by simultaneous operation of the two communication modules, and meanwhile, because the device system does not change the working parameters when the communication modules operate (e.g., does not reduce the data signal transmission of the communication modules) Power) so that the communication performance of the system of devices is not adversely affected.

In an optional embodiment of the communication control method in the present application, the controlling the first communication module and the second communication module to transmit the data signal in a time-sharing manner specifically includes:

alternatively, the first and second electrodes may be,

Specifically, when the first communication module and the second communication module are controlled to transmit data signals in a time-sharing manner, as a possible implementation manner, each first communication sub-module in the first communication module that needs to transmit data signals and each second communication sub-module in the second communication module that needs to transmit data signals can be controlled to be in a data transmission state, and each first communication sub-module that needs to transmit data signals and each second communication sub-module that needs to transmit data signals are controlled in a time-sharing manner to transmit data signals in a time-sharing manner, for example, two Wi-Fi sub-modules in a Wi-Fi module and two 5G sub-modules in a 5G module are controlled to be in a data transmission state, and the two Wi-Fi sub-modules and the two 5G sub-modules are controlled in a time-sharing manner to transmit data signals, and the like, therefore, only one communication module transmits data signals at each specific moment, and the space energy (radiation energy) density of the equipment is effectively reduced.

As another possible implementation manner, it may also be controlled that one type of communication sub-module of each first communication sub-module that needs to transmit a data signal in the first communication module and each second communication sub-module that needs to transmit a data signal in the second communication module is in a data transmission state, and the other type of communication sub-module is in a data reception state, for example, specifically, for a 5G module and a Wi-Fi module that need to simultaneously transmit a data signal by using two uplinks, two 5G sub-modules corresponding to two uplinks in the 5G module may be maintained in a data transmission state, and two Wi-Fi sub-modules corresponding to two uplinks in the Wi-Fi module may be switched from a data transmission state to a data reception state, so that at each specific time, only one type of communication modules transmits a data signal, the spatial energy (radiant energy) density of the device is effectively reduced.

In an optional embodiment of the communication control method according to the application, the controlling at least one first communication sub-module in the first communication module and at least one second communication sub-module in the second communication module to transmit a data signal (where the positions of the at least one first communication sub-module and the at least one second communication sub-module meet a specific condition) may specifically include:

Specifically, when the at least one first communication sub-module and the at least one second communication sub-module whose positions meet the specific condition are controlled to transmit data signals, as a possible implementation manner, the at least one first communication sub-module and the at least one second communication sub-module whose positions meet the specific condition may be controlled to transmit data signals at the same time, for example, two Wi-Fi sub-modules and two 5G sub-modules whose positions meet the specific condition are controlled to transmit data signals at the same time, and the like. As described above, the specific condition is a condition that can be used to indicate that the layout position of each communication submodule (or a part of the communication submodules) which needs to transmit data signals in the electronic device is relatively far away, so that, in this implementation, even if the at least one first communication submodule and the at least one second communication submodule simultaneously transmit data signals, since the layout positions of the at least one first communication submodule and the at least one second communication submodule in the electronic device are relatively far away, the effect of effectively reducing the spatial energy (radiation energy) density when each communication submodule transmits data can be achieved.

As another possible implementation manner, the at least one first communication submodule and the at least one second communication submodule, the positions of which meet a specific condition, may also be controlled to transmit data signals in a time-sharing manner, and the implementation manner of transmitting data signals in a time-sharing manner may include two types: 1) controlling the at least one first communication submodule and the at least one second communication submodule to be in a data transmission state, and controlling the at least one first communication submodule and the at least one second communication submodule to transmit data signals in a time-sharing mode in a time-sharing control mode; 2) one type of communication sub-module of the at least one first communication sub-module and the at least one second communication sub-module is controlled to be in a data transmitting state, and the other type of communication sub-module is controlled to be in a data receiving state, so that only one type of communication module transmits data signals at each specific moment, and the spatial energy (radiation energy) density of the equipment is effectively reduced.

In this embodiment, by performing the time-sharing control on the first communication module and the second communication module and/or performing the location-based communication control, the spatial energy (radiation energy) density of each communication sub-module during data transmission can be effectively reduced, so that the specific absorption rate of the first communication module and the second communication module during simultaneous operation is effectively reduced, and meanwhile, since the working parameters of each communication module during operation are not changed (for example, the data signal transmission power of each communication module is not reduced), the communication performance of the device system is not adversely affected.

In an optional embodiment of the communication control method described in this application, referring to the flowchart of the communication control method shown in fig. 7, when responding to the detection information that can be used to indicate that the first communication module and the second communication module need to operate simultaneously, the following operations may be further performed:

step 701, determining a first priority of the first communication module for transmitting the data signal, and determining a second priority of the second communication module for transmitting the data signal; and triggering a matched communication mode to carry out communication control on the first communication module and the second communication module based on the first priority and the second priority.

When the calling information of the device system to the first communication module and the second communication module is detected, that is, when the device system needs to transmit data signals by using the first communication module and the second communication module at the same time, that is, when the detection information which can indicate that the first communication module and the second communication module need to work at the same time is obtained, the corresponding communication mode of the communication modes can be triggered to perform communication control on the first communication module and the second communication module by considering the first priority of the data signals transmitted by the first communication module and the second priority of the data signals transmitted by the second communication module.

In specific implementation, the first priority of the data signal transmitted by the first communication module and the second priority of the data signal transmitted by the second communication module may be determined according to the priority of the service type of the data to be transmitted of the first communication module and the second communication module, and/or the priority of the first communication module and the priority of the second communication module.

For example, it is assumed that at present, two 5G sub-modules in a 5G module need to be used to transmit an instant message of an instant messaging service, and at the same time, two Wi-Fi sub-modules in a Wi-Fi module need to be used to transmit download data corresponding to the download service (for example, a mobile phone serving as a Wi-Fi hotspot transmits movie data to another mobile phone, so that a movie episode is downloaded on another mobile phone, etc.), and considering that the real-time requirement of the instant messaging service is higher than that of the download service, a priority level of the instant message transmitted by the 5G module may be set higher than a priority level of the download data transmitted by the Wi-Fi module; as another possible implementation manner, if the system defaults or the user sets the priority of the different communication modules, for example, assuming that the priority of the Wi-Fi module is set to be higher than that of the 5G module, the priority of the different communication modules when transmitting data signals can be determined according to the system setting condition; in addition, the priority levels of the service types of the data to be transmitted of the first communication module and the second communication module and the priority levels of the first communication module and the second communication module can be integrated in a weighting calculation mode to calculate the first priority level of the data signal transmitted by the first communication module and the second priority level of the data signal transmitted by the second communication module.

After determining a first priority of the first communication module for transmitting the data signal and a second priority of the second communication module for transmitting the data signal, performing the following communication control on the first communication module and the second communication module based on the first priority and the second priority:

1) if the first priority is equal to the second priority, triggering execution: controlling at least one first communication sub-module and at least one second communication sub-module, the positions of which meet specific conditions, in the first communication module and the second communication module to simultaneously transmit data signals; or, controlling at least one first communication sub-module and at least one second communication sub-module in the first communication module and the second communication module to transmit data signals in a time-division manner;

in this application, the first communication module has a time division duplex characteristic, for example, specifically, a Wi-Fi module having the time division duplex characteristic, and the second communication module has a time division duplex characteristic and a frequency division duplex characteristic, for example, specifically, a 5G module having the time division duplex characteristic and the frequency division duplex characteristic, and of course, alternatively, in a specific implementation, the first communication module may also have the time division duplex characteristic and the frequency division duplex characteristic, and the second communication module may have the time division duplex characteristic, which is not limited in this embodiment.

Taking the example that the first communication module has a tdd characteristic, and the second communication module has a tdd characteristic and a fdd characteristic, when the first priority is equal to the second priority, the first communication module and the second communication module may be specifically controlled by the following processing:

For example, assuming that the first communication module is a Wi-Fi module and operates based on a time division duplex characteristic, and the second communication module is a 5G module and also operates based on a time division duplex characteristic, when the Wi-Fi module and the 5G module transmit data signals at the same time, two Wi-Fi sub-modules and two 5G sub-modules of the Wi-Fi module and the 5G module, which have positions meeting a specific condition, may be controlled to transmit data signals at the same time, in this manner, although the two Wi-Fi sub-modules and the two 5G sub-modules transmit data signals at the same time, since the two Wi-Fi sub-modules and the two 5G sub-modules have relatively long layout positions in the electronic device (which meet the specific condition that the representation positions are relatively long), the effect of effectively reducing the spatial energy (radiation energy) density when each communication sub-module transmits data may also be achieved; or, two Wi-Fi sub-modules in the Wi-Fi module and two 5G sub-modules in the 5G module may be selected, and the two selected Wi-Fi sub-modules and the two 5G sub-modules are controlled to transmit data signals in a time division manner, in which only one communication module transmits data signals at each specific time, so that the spatial energy (radiation energy) density of the device is effectively reduced.

2) If the first priority is lower than the second priority, triggering to execute: controlling at least one second communication sub-module in the second communication module to be in a data transmitting state and at least one first communication sub-module in the first communication module to be in a data receiving state until a first condition is met, and controlling the at least one first communication sub-module to be in the data transmitting state;

the first condition may be, but is not limited to: the time length of each second communication submodule in a data transmitting state and the time length of each first communication submodule in a data receiving state reach set time length, such as 6s and 10 s; or, each second communication sub-module has completed the current data transmission task (suitable for the case that the amount of data signals to be transmitted by each second communication sub-module is small), and so on.

In the method, each first communication sub-module with low priority of the transmitted data signals is controlled to be in a data receiving state, so that the data signal transmitting requirement of each second communication sub-module with high priority of the transmitted data signals can be met preferentially; and when the first condition is met, controlling each first communication sub-module to be in a data transmission state, and aiming at further effectively meeting the requirement (although the priority is low, the requirement still exists) that each first communication sub-module transmits data signals.

After each first communication sub-module is switched back from the data receiving state to the data transmitting state, the present embodiment does not limit the communication manner between each first communication sub-module switched back to the data transmitting state and each second communication sub-module in the data transmitting state, for example, each second communication sub-module in the data transmitting state and each first communication sub-module in the data transmitting state may be controlled in a time-division control manner to transmit data in a time-division manner, or when the positions of each second communication sub-module in the data transmitting state and each first communication sub-module in the data transmitting state satisfy the above specific condition, the two types of modules may also be controlled to transmit data signals simultaneously; or, each second communication sub-module may have completed its current data transmission task, so that only the first communication sub-module is controlled to transmit the data signal.

3) If the first priority is higher than the second priority, triggering to execute: and controlling at least one first communication sub-module in the first communication module to be in a data transmitting state and at least one second communication sub-module in the second communication module to be in a data receiving state until a second condition is met, and controlling the at least one second communication sub-module to be in the data transmitting state.

The second condition may be, but is not limited to: the time length of each first communication submodule in a data transmitting state and the time length of each second communication submodule in a data receiving state reach set time length, such as 6s and 10 s; or, each first communication sub-module completes the current data transmission task (suitable for the situation that the amount of data signals to be transmitted currently by each first communication sub-module is small), and so on.

In the method, each second communication submodule with low priority for transmitting data signals is controlled to be in a data receiving state, so that the data signal transmitting requirement of each first communication submodule with high priority for transmitting data signals can be met preferentially; and controlling the second communication sub-modules to be in a data transmission state when the second condition is met, so as to further effectively meet the requirement (although the priority is low, the requirement still exists) that the second communication sub-modules transmit data signals.

After each second communication sub-module is switched back to the data transmission state from the data receiving state, the present embodiment also does not limit the communication manner between each second communication sub-module switched back to the data transmission state and each first communication sub-module in the data transmission state, for example, each second communication sub-module in the data transmission state and each first communication sub-module in the data transmission state may be controlled in a time-division control manner to transmit data in a time-division manner, or when the positions of each second communication sub-module in the data transmission state and each first communication sub-module in the data transmission state satisfy the above specific condition, the two types of modules may also be controlled to transmit data signals simultaneously; or, each first communication sub-module may have completed its current data transmission task, so that only the second communication sub-module is controlled to transmit the data signal.

In this embodiment, a first priority of the first communication module for transmitting the data signal and a second priority of the second communication module for transmitting the data signal are considered in combination to trigger a matched communication mode to perform communication control on the first communication module and the second communication module, so that the signal transmission efficiency of the high-priority data or communication module is effectively ensured.

In an optional embodiment of the communication control method, when the electronic device further includes the first data transmission link, the first data reception link, the second data transmission link, the second data reception link, the at least one first switch, and the at least one second switch, which correspond to the first communication sub-module, the first switch is specifically controlled to control the first communication sub-module to be connected with the corresponding first data transmission link or first data reception link, so as to control the first communication sub-module to be in the data transmission state or the data reception state; similarly, the second switch can be controlled to control the second communication sub-module to be switched on with the corresponding second data sending link or second data receiving link, so as to control the second communication sub-module to be in a data transmitting state or a data receiving state.

The first data transmission link of the first communication sub-module and the second data transmission link of the second communication sub-module may include, but are not limited to, a Power Amplifier (PA); the first data receiving link of the first communication sub-module and the second data receiving link of the second communication sub-module may include, but are not limited to, a Low Noise Amplifier (LNA).

The first switch and the second switch can be single-pole double-throw or double-pole double-throw radio frequency switches, the number of the first switch and the second switch can be respectively 1 or more, and in practical application, the first switch and the second switch can be selected according to the circuit design requirements.

With reference to fig. 4, fig. 4 provides an exemplary diagram of a control circuit for controlling communication between the Wi-Fi module and the 5G module when the 5G module operates based on a Time Division Duplex (TDD) characteristic, where the first communication module is a Wi-Fi module (supporting time division duplex), and the second communication module is a 5G module (supporting time division duplex and frequency division duplex).
