Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
The first embodiment,
The embodiment of the present invention provides a method for implementing dual-mode coexistence on a WIFI chip, as shown in fig. 1, including:
step 101: obtaining a control instruction for indicating coexistence of an STA mode and an AP mode;
step 102: responding to the control instruction, loading an NV file, wherein the NV file at least comprises control information aiming at a communication channel under the coexistence of an STA mode and an AP mode;
step 103: and under the control of the NV file, controlling a communication channel of a frequency band supported by the WIFI chip so as to enable the STA mode and the AP mode to coexist.
Here, the STA mode is used to indicate a mode that can establish a communication connection with a network side through WIFI and interact data with the network side through the communication connection;
the AP mode is used for representing a mode which can establish communication connection with a network side through a WIFI chip, interact data with the network side through the communication connection, and allow other electronic equipment to access as a wireless access point and access the network through the wireless access point.
The manner of obtaining the control instruction for indicating the coexistence of the STA mode and the AP mode may be that a user selects which mode the WIFI function of the current electronic device is in through a setting interface, for example, referring to fig. 2, an option of "STA mode and AP mode" may be selected from the drawing, so as to obtain the control instruction for dual-mode coexistence.
It should be noted that the scenario shown in fig. 2 is only one possible operation manner, and in addition, the scenario may not be directly displayed in the STA mode, and when the "wireless local area network" is selected, the STA mode is determined to be entered, and when the "personal hotspot" is selected, the AP mode is determined to be entered, and if the option of "wireless local area network and personal hotspot coexisting" is provided and can be selected, the obtained control instruction for indicating the coexistence of the STA mode and the AP mode may be determined.
Further, the loading the NV file in response to the control instruction may be: and calling a preset NV file from the WIFI chip when the control instruction is detected.
The content included in the NV file may include, in addition to the control information for the communication channel in the coexistence of the STA mode and the AP mode, the control information for the communication channel that needs to be acquired when the WIFI chip is in the STA mode, and the control information for the communication channel that needs to be acquired when the WIFI chip is in the AP mode. That is, for each mode, the NV file may have an identification information, and once a control instruction indicating that the mode is in a certain mode is received, the corresponding identification information is found from the NV file according to the identification corresponding to the mode, and the control information of the communication channel in the mode is extracted and obtained based on the identification information.
Further, the frequency bands supported by the WIFI chip under the control of the NV file may generally include two types, namely 2.5G and 5G.
Therefore, by adopting the scheme, the control information for the communication channel under the coexistence of the STA mode and the AP mode of the NV file can be obtained by loading the NV file, so that the WIFI chip can be in the coexistence of the STA mode and the AP mode. Therefore, the electronic equipment can be used as an access point to access the network and can also be used as an access point to provide the network for other equipment, the working mode of the WIFI chip in the electronic equipment is expanded, and the application scene of the electronic equipment is promoted.
Example II,
The embodiment of the present invention provides a method for implementing dual-mode coexistence on a WIFI chip, as shown in fig. 1, including:
step 101: obtaining a control instruction for indicating coexistence of an STA mode and an AP mode;
step 102: responding to the control instruction, loading an NV file, wherein the NV file at least comprises control information aiming at a communication channel under the coexistence of an STA mode and an AP mode;
step 103: and under the control of the NV file, controlling a communication channel of a frequency band supported by the WIFI chip so as to enable the STA mode and the AP mode to coexist.
Here, the STA mode is used to indicate a mode that can establish a communication connection with a network side through WIFI and interact data with the network side through the communication connection;
the AP mode is used for representing a mode which can establish communication connection with a network side through a WIFI chip, interact data with the network side through the communication connection, and allow other electronic equipment to access as a wireless access point and access the network through the wireless access point.
The manner of obtaining the control instruction for indicating the coexistence of the STA mode and the AP mode may be that a user selects which mode the WIFI function of the current electronic device is in through a setting interface, for example, referring to fig. 2, an option of "STA mode and AP mode" may be selected from the drawing, so as to obtain the control instruction for dual-mode coexistence.
It should be noted that the scenario shown in fig. 2 is only one possible operation manner, and in addition, the scenario may not be directly displayed in the STA mode, and when the "wireless local area network" is selected, the STA mode is determined to be entered, and when the "personal hotspot" is selected, the AP mode is determined to be entered, and if the option of "wireless local area network and personal hotspot coexisting" is provided and can be selected, the obtained control instruction for indicating the coexistence of the STA mode and the AP mode may be determined.
Further, the loading the NV file in response to the control instruction may be: and calling a preset NV file from the WIFI chip when the control instruction is detected.
The content included in the NV file may include, in addition to the control information for the communication channel in the coexistence of the STA mode and the AP mode, the control information for the communication channel that needs to be acquired when the WIFI chip is in the STA mode, and the control information for the communication channel that needs to be acquired when the WIFI chip is in the AP mode. That is, for each mode, the NV file may have an identification information, and once a control instruction indicating that the mode is in a certain mode is received, the corresponding identification information is found from the NV file according to the identification corresponding to the mode, and the control information of the communication channel in the mode is extracted and obtained based on the identification information.
Further, the present embodiment provides a specific implementation manner, and the following description is given by taking an implementation manner in which the STA mode and the AP mode are in different transmission frequency bands as an example in the present embodiment, specifically as follows:
the controlling the communication channel of the frequency band supported by the WIFI chip under the control of the NV file comprises:
selecting a first communication sub-channel and a second communication sub-channel which are distributed in different transmission frequency bands under the condition that an STA mode and the AP mode coexist from the NV file;
the first communication sub-channel is controlled for supporting data interaction in an STA mode, and the second communication sub-channel is controlled for supporting data interaction in an AP mode.
Wherein, the first communication sub-channel and the second communication sub-channel with different transmission frequency bands can be set according to different scenes corresponding to different frequency bands supported by WIFI, such as:
in a scenario one, which is the most commonly used scenario of 2.4G, if the WIFI chip only supports a frequency band of 2.4G, referring to fig. 3, channel allocation of a 2.5G frequency band is taken as an example, wherein, assuming that each channel frequency band distribution diagram of WIFI 2.4G, there are non-interfering channels (1, 6, 11) in the whole frequency band. Then the first communication sub-channel may be designated as channel 1 and the second communication sub-channel as channel 6; alternatively, the first communication sub-channel is channel 11 and the second communication sub-channel is channel 1.
In a second scenario, when the WIFI chip can support channels of two frequency bands, i.e., 2.4G and 5G, first, a division diagram (fig. 4) of the 5G frequency band is combined to describe channel frequency band division in the 5G frequency band, where 802.11a.n is shown in fig. 4, and distribution diagrams of channel frequency bands of WIFI 5G under different bandwidths in the ac specification are shown. The channels available for WiFi 5G in China are CH 36-48 and CH 149-165.
It can be seen from fig. 3 and 4 that the frequency bands of 2.4G and 5G are far apart. That is to say, when the WIFI chip can support channels of two frequency bands, 2.4G and 5G, the first communication sub-channel may be set to be a channel supported by any one of the 2.4G frequency bands, and the second communication sub-channel may be set to be a channel supported by any one of the 5G frequency bands, for example, the first communication sub-channel may be set to be the channel 6, and the second communication sub-channel may be set to be the channel 40.
Preferably, for the scenario provided in this embodiment, it may further be specified that the transmission frequency band of the first communication sub-channel is set to be higher than the transmission frequency band of the second communication sub-channel. That is to say, for the second scenario, when the WIFI chip can support channels of two frequency bands, namely 2.4G and 5G, the first communication sub-channel may be set to be a channel frequency band supported by any one of the 5G frequency bands, and the second communication sub-channel may be set to be a channel frequency band supported by any one of the 2.4G frequency bands. For example, the first communication sub-channel may be set to be channel 48 and the second communication sub-channel may be set to be channel 11.
Therefore, by adopting the scheme, the control information for the communication channel under the coexistence of the STA mode and the AP mode of the NV file can be obtained by loading the NV file, so that the WIFI chip can be in the coexistence of the STA mode and the AP mode. Therefore, the electronic equipment can be used as an access point to access the network and can also be used as an access point to provide the network for other equipment, the working mode of the WIFI chip in the electronic equipment is expanded, and the application scene of the electronic equipment is promoted.
Example III,
The embodiment of the present invention provides a method for implementing dual-mode coexistence on a WIFI chip, as shown in fig. 1, including:
step 101: obtaining a control instruction for indicating coexistence of an STA mode and an AP mode;
step 102: responding to the control instruction, loading an NV file, wherein the NV file at least comprises control information aiming at a communication channel under the coexistence of an STA mode and an AP mode;
step 103: and under the control of the NV file, controlling a communication channel of a frequency band supported by the WIFI chip so as to enable the STA mode and the AP mode to coexist.
Here, the STA mode is used to indicate a mode that can establish a communication connection with a network side through WIFI and interact data with the network side through the communication connection;
the AP mode is used for representing a mode which can establish communication connection with a network side through a WIFI chip, interact data with the network side through the communication connection, and allow other electronic equipment to access as a wireless access point and access the network through the wireless access point.
The manner of obtaining the control instruction for indicating the coexistence of the STA mode and the AP mode may be that a user selects which mode the WIFI function of the current electronic device is in through a setting interface, for example, referring to fig. 2, an option of "STA mode and AP mode" may be selected from the drawing, so as to obtain the control instruction for dual-mode coexistence.
It should be noted that the scenario shown in fig. 2 is only one possible operation manner, and in addition, the scenario may not be directly displayed in the STA mode, and when the "wireless local area network" is selected, the STA mode is determined to be entered, and when the "personal hotspot" is selected, the AP mode is determined to be entered, and if the option of "wireless local area network and personal hotspot coexisting" is provided and can be selected, the obtained control instruction for indicating the coexistence of the STA mode and the AP mode may be determined.
Further, the loading the NV file in response to the control instruction may be: and calling a preset NV file from the WIFI chip when the control instruction is detected.
The content included in the NV file may include, in addition to the control information for the communication channel in the coexistence of the STA mode and the AP mode, the control information for the communication channel that needs to be acquired when the WIFI chip is in the STA mode, and the control information for the communication channel that needs to be acquired when the WIFI chip is in the AP mode. That is, for each mode, the NV file may have an identification information, and once a control instruction indicating that the mode is in a certain mode is received, the corresponding identification information is found from the NV file according to the identification corresponding to the mode, and the control information of the communication channel in the mode is extracted and obtained based on the identification information.
Further, the present embodiment provides a specific implementation manner different from the foregoing embodiment, and the following description is given by taking an implementation manner in which the STA mode and the AP mode are in different transmission periods as an example, and the specific implementation manner is as follows:
the controlling the communication channel of the frequency band supported by the WIFI chip under the control of the NV file comprises:
selecting a first communication sub-channel and a second communication sub-channel which are allocated with different working time slots under the condition that an STA mode and the AP mode coexist from the NV file;
the first communication sub-channel is controlled for supporting data interaction in an STA mode, and the second communication sub-channel is controlled for supporting data interaction in an AP mode.
That is, in this scenario, first, the first communication sub-channel and the second communication sub-channel both use the same frequency band, but operate in different time slots. The present embodiment can be described by using a channel in the 2.4G band shown in fig. 3, and can also be described by using a channel in the 5G band shown in fig. 4, and the band is not limited here.
Specifically, the first communication sub-channel includes an uplink working time slot set as at least one first time slot and a downlink working time slot set as at least one second time slot; correspondingly, the second communication sub-channel comprises an uplink working time slot set as at least one third time slot and a downlink working time slot set as at least one fourth time slot; the first time slot, the second time slot, the third time slot and the fourth time slot are all different.
It should be noted that, for the time slot division of the communication sub-channels, the time slot division may be preset at the terminal side and the network side according to the actual situation, for example, a radio frame duration may be set to be N, where M time slots are provided, that is, the duration of each time slot is not greater than N/M, in this embodiment, at least four time slots may exist in one radio frame, for example, referring to fig. 5, it is assumed that a first communication sub-channel adopts a time slot 1 as a first time slot, that is, an uplink time slot, a time slot 2 as a second time slot, that is, a downlink time slot, a second communication sub-channel adopts a time slot 3 as an uplink time slot, and a time slot 4 as a fourth time slot, that is, a downlink time slot. By such time slot division as in fig. 5, the first communication sub-channel and the second communication sub-channel can be distinguished in time, so as to avoid the problem of channel collision between the two modes of STA and AP. It can be understood that fig. 5 only shows an example where each communication subchannel has two time slots, in the actual processing, more uplink and downlink time slots can be set for each communication subchannel, and the specific data processing manner for each time slot is the same as that in the example in fig. 5, and therefore, details are not described here.
In addition, it should be noted that the setting of the uplink timeslot and the downlink timeslot corresponding to the first communication sub-channel may be also set in advance on the network side, for example, when it is determined that the electronic device enters a scenario in which an STA mode and an AP mode coexist, a notification may be sent to the network side in advance, so that the network side obtains the scenario in which the electronic device is to enter a dual-mode coexistence, and the electronic device uses communication sub-channels in different timeslots to respectively interact data in the two modes, at this time, the network side may respectively interact data to the electronic device side through different uplink and downlink timeslots according to preset information for communication sub-channels in different modes.
In this embodiment, referring to fig. 6, a flow may be described again, and when the WIFI chip is in any one of the STA mode and the AP mode, the WIIF chip may be controlled to operate in the default frequency band and channel; once the WIFI chip is controlled to be in a scene where the STA mode and the AP mode coexist, the STA mode and the AP mode are subjected to time-sharing control based on control information in the NV file, and finally the STA mode and the AP mode can coexist.
Therefore, by adopting the scheme, the control information for the communication channel under the coexistence of the STA mode and the AP mode of the NV file can be obtained by loading the NV file, so that the WIFI chip can be in the coexistence of the STA mode and the AP mode. Therefore, the electronic equipment can be used as an access point to access the network and can also be used as an access point to provide the network for other equipment, the working mode of the WIFI chip in the electronic equipment is expanded, and the application scene of the electronic equipment is promoted.
Example four,

an information obtaining unit 71, configured to obtain a control instruction for instructing coexistence of the STA mode and the AP mode;
a processing unit 72, configured to respond to the control instruction, load an NV file, where the NV file at least includes control information for a communication channel when the STA mode and the AP mode coexist; and under the control of the NV file, controlling a communication channel of a frequency band supported by the WIFI chip so as to enable the STA mode and the AP mode to coexist.
Here, the STA mode is used to indicate a mode that can establish a communication connection with a network side through WIFI and interact data with the network side through the communication connection;
the AP mode is used for representing a mode which can establish communication connection with a network side through a WIFI chip, interact data with the network side through the communication connection, and allow other electronic equipment to access as a wireless access point and access the network through the wireless access point.
The manner of obtaining the control instruction for indicating the coexistence of the STA mode and the AP mode may be that a user selects which mode the WIFI function of the current electronic device is in through a setting interface, for example, referring to fig. 2, an option of "STA mode and AP mode" may be selected from the drawing, so as to obtain the control instruction for dual-mode coexistence.
It should be noted that the scenario shown in fig. 2 is only one possible operation manner, and in addition, the scenario may not be directly displayed in the STA mode, and when the "wireless local area network" is selected, the STA mode is determined to be entered, and when the "personal hotspot" is selected, the AP mode is determined to be entered, and if the option of "wireless local area network and personal hotspot coexisting" is provided and can be selected, the obtained control instruction for indicating the coexistence of the STA mode and the AP mode may be determined.
Further, the loading the NV file in response to the control instruction may be: and calling a preset NV file from the WIFI chip when the control instruction is detected.
In addition to the control information for the communication channel when the STA mode and the AP mode coexist, the content included in the NV file may be control information for the communication channel when the WIFI chip is in the STA mode, and the processing unit 72 is configured to acquire the control information for the communication channel when the WIFI chip is in the AP mode. That is, for each mode, the NV file may have an identification information, and once a control instruction indicating that the mode is in a certain mode is received, the corresponding identification information is found from the NV file according to the identification corresponding to the mode, and the control information of the communication channel in the mode is extracted and obtained based on the identification information.
Further, the frequency bands supported by the WIFI chip under the control of the NV file may generally include two types, namely 2.5G and 5G.
Therefore, by adopting the scheme, the control information for the communication channel under the coexistence of the STA mode and the AP mode of the NV file can be obtained by loading the NV file, so that the WIFI chip can be in the coexistence of the STA mode and the AP mode. Therefore, the electronic equipment can be used as an access point to access the network and can also be used as an access point to provide the network for other equipment, the working mode of the WIFI chip in the electronic equipment is expanded, and the application scene of the electronic equipment is promoted.
Example V,
An embodiment of the present invention provides an electronic device, as shown in fig. 7, the electronic device includes:
an information obtaining unit 71, configured to obtain a control instruction for instructing coexistence of the STA mode and the AP mode;
a processing unit 72, configured to respond to the control instruction, load an NV file, where the NV file at least includes control information for a communication channel when the STA mode and the AP mode coexist; and under the control of the NV file, controlling a communication channel of a frequency band supported by the WIFI chip so as to enable the STA mode and the AP mode to coexist.
Here, the STA mode is used to indicate a mode that can establish a communication connection with a network side through WIFI and interact data with the network side through the communication connection;
the AP mode is used for representing a mode which can establish communication connection with a network side through a WIFI chip, interact data with the network side through the communication connection, and allow other electronic equipment to access as a wireless access point and access the network through the wireless access point.
The manner of obtaining the control instruction for indicating the coexistence of the STA mode and the AP mode may be that a user selects which mode the WIFI function of the current electronic device is in through a setting interface, for example, referring to fig. 2, an option of "STA mode and AP mode" may be selected from the drawing, so as to obtain the control instruction for dual-mode coexistence.
It should be noted that the scenario shown in fig. 2 is only one possible operation manner, and in addition, the scenario may not be directly displayed in the STA mode, and when the "wireless local area network" is selected, the STA mode is determined to be entered, and when the "personal hotspot" is selected, the AP mode is determined to be entered, and if the option of "wireless local area network and personal hotspot coexisting" is provided and can be selected, the obtained control instruction for indicating the coexistence of the STA mode and the AP mode may be determined.
Further, the loading the NV file in response to the control instruction may be: and calling a preset NV file from the WIFI chip when the control instruction is detected.
The content included in the NV file may include, in addition to the control information for the communication channel in the coexistence of the STA mode and the AP mode, the control information for the communication channel that needs to be acquired when the WIFI chip is in the STA mode, and the control information for the communication channel that needs to be acquired when the WIFI chip is in the AP mode. That is, for each mode, the NV file may have an identification information, and once a control instruction indicating that the mode is in a certain mode is received, the corresponding identification information is found from the NV file according to the identification corresponding to the mode, and the control information of the communication channel in the mode is extracted and obtained based on the identification information.
Further, the present embodiment provides a specific implementation manner, and the following description is given by taking an implementation manner in which the STA mode and the AP mode are in different transmission frequency bands as an example in the present embodiment, specifically as follows:
a processing unit 72, configured to select, from the NV file, a first communication sub-channel and a second communication sub-channel that are allocated in different transmission frequency bands and allocated in a case where the STA mode and the AP mode coexist; the first communication sub-channel is controlled for supporting data interaction in an STA mode, and the second communication sub-channel is controlled for supporting data interaction in an AP mode.
Wherein, the first communication sub-channel and the second communication sub-channel with different transmission frequency bands can be set according to different scenes corresponding to different frequency bands supported by WIFI, such as:
in a scenario one, which is the most commonly used scenario of 2.4G, if the WIFI chip only supports a frequency band of 2.4G, referring to fig. 3, channel allocation of a 2.5G frequency band is taken as an example, wherein, assuming that each channel frequency band distribution diagram of WIFI 2.4G, there are non-interfering channels (1, 6, 11) in the whole frequency band. Then the first communication sub-channel may be designated as channel 1 and the second communication sub-channel as channel 6; alternatively, the first communication sub-channel is channel 11 and the second communication sub-channel is channel 1.
In a second scenario, when the WIFI chip can support channels of two frequency bands, i.e., 2.4G and 5G, first, a division diagram (fig. 4) of the 5G frequency band is combined to describe channel frequency band division in the 5G frequency band, where 802.11a.n is shown in fig. 4, and distribution diagrams of channel frequency bands of WIFI 5G under different bandwidths in the ac specification are shown. The channels available for WiFi 5G in China are CH 36-48 and CH 149-165.
It can be seen from fig. 3 and 4 that the frequency bands of 2.4G and 5G are far apart. That is to say, when the WIFI chip can support channels of two frequency bands, 2.4G and 5G, the first communication sub-channel may be set to be a channel supported by any one of the 2.4G frequency bands, and the second communication sub-channel may be set to be a channel supported by any one of the 5G frequency bands, for example, the first communication sub-channel may be set to be the channel 6, and the second communication sub-channel may be set to be the channel 37.
Preferably, for the scenario provided in this embodiment, it may further be specified that the transmission frequency band of the first communication sub-channel is set to be higher than the transmission frequency band of the second communication sub-channel. That is to say, for the second scenario, when the WIFI chip can support channels of two frequency bands, namely 2.4G and 5G, the first communication sub-channel may be set to be a channel frequency band supported by any one of the 5G frequency bands, and the second communication sub-channel may be set to be a channel frequency band supported by any one of the 2.4G frequency bands. For example, the first communication sub-channel may be set to be channel 48 and the second communication sub-channel may be set to be channel 11.
Therefore, by adopting the scheme, the control information for the communication channel under the coexistence of the STA mode and the AP mode of the NV file can be obtained by loading the NV file, so that the WIFI chip can be in the coexistence of the STA mode and the AP mode. Therefore, the electronic equipment can be used as an access point to access the network and can also be used as an access point to provide the network for other equipment, the working mode of the WIFI chip in the electronic equipment is expanded, and the application scene of the electronic equipment is promoted.

a processing unit 72, configured to respond to the control instruction, load an NV file, where the NV file at least includes control information for a communication channel when the STA mode and the AP mode coexist; and under the control of the NV file, controlling a communication channel of a frequency band supported by the WIFI chip so as to enable the STA mode and the AP mode to coexist.
Here, the STA mode is used to indicate a mode that can establish a communication connection with a network side through WIFI and interact data with the network side through the communication connection;
the AP mode is used for representing a mode which can establish communication connection with a network side through a WIFI chip, interact data with the network side through the communication connection, and allow other electronic equipment to access as a wireless access point and access the network through the wireless access point.
The manner of obtaining the control instruction for indicating the coexistence of the STA mode and the AP mode may be that a user selects which mode the WIFI function of the current electronic device is in through a setting interface, for example, referring to fig. 2, an option of "STA mode and AP mode" may be selected from the drawing, so as to obtain the control instruction for dual-mode coexistence.
It should be noted that the scenario shown in fig. 2 is only one possible operation manner, and in addition, the scenario may not be directly displayed in the STA mode, and when the "wireless local area network" is selected, the STA mode is determined to be entered, and when the "personal hotspot" is selected, the AP mode is determined to be entered, and if the option of "wireless local area network and personal hotspot coexisting" is provided and can be selected, the obtained control instruction for indicating the coexistence of the STA mode and the AP mode may be determined.
Further, the loading the NV file in response to the control instruction may be: and calling a preset NV file from the WIFI chip when the control instruction is detected.
The content included in the NV file may include, in addition to the control information for the communication channel in the coexistence of the STA mode and the AP mode, the control information for the communication channel that needs to be acquired when the WIFI chip is in the STA mode, and the control information for the communication channel that needs to be acquired when the WIFI chip is in the AP mode. That is, for each mode, the NV file may have an identification information, and once a control instruction indicating that the mode is in a certain mode is received, the corresponding identification information is found from the NV file according to the identification corresponding to the mode, and the control information of the communication channel in the mode is extracted and obtained based on the identification information.
Further, the present embodiment provides a specific implementation manner different from the foregoing embodiment, and the following description is given by taking an implementation manner in which the STA mode and the AP mode are in different transmission periods as an example, and the specific implementation manner is as follows:
the processing unit 72 is configured to select, from the NV file, a first communication sub-channel and a second communication sub-channel that are allocated in different working timeslots under the coexistence of the STA mode and the AP mode; the first communication sub-channel is controlled for supporting data interaction in an STA mode, and the second communication sub-channel is controlled for supporting data interaction in an AP mode.
That is, in this scenario, first, the first communication sub-channel and the second communication sub-channel both use the same frequency band, but operate in different time slots. The present embodiment can be described by using a channel in the 2.4G band shown in fig. 3, and can also be described by using a channel in the 5G band shown in fig. 4, and the band is not limited here.
Specifically, the first communication sub-channel includes an uplink working time slot set as at least one first time slot and a downlink working time slot set as at least one second time slot; correspondingly, the second communication sub-channel comprises an uplink working time slot set as at least one third time slot and a downlink working time slot set as at least one fourth time slot; the first time slot, the second time slot, the third time slot and the fourth time slot are all different.
It should be noted that, for the time slot division of the communication sub-channels, the time slot division may be preset at the terminal side and the network side according to the actual situation, for example, a radio frame duration may be set to be N, where M time slots are provided, that is, the duration of each time slot is not greater than N/M, in this embodiment, at least four time slots may exist in one radio frame, for example, referring to fig. 5, it is assumed that a first communication sub-channel adopts a time slot 1 as a first time slot, that is, an uplink time slot, a time slot 2 as a second time slot, that is, a downlink time slot, a second communication sub-channel adopts a time slot 3 as an uplink time slot, and a time slot 4 as a fourth time slot, that is, a downlink time slot. By such time slot division as in fig. 5, the first communication sub-channel and the second communication sub-channel can be distinguished in time, so as to avoid the problem of channel collision between the two modes of STA and AP. It can be understood that fig. 5 only shows an example where each communication subchannel has two time slots, in the actual processing, more uplink and downlink time slots can be set for each communication subchannel, and the specific data processing manner for each time slot is the same as that in the example in fig. 5, and therefore, details are not described here.
In addition, it should be noted that the setting of the uplink timeslot and the downlink timeslot corresponding to the first communication sub-channel may be also set in advance on the network side, for example, when it is determined that the electronic device enters a scenario in which an STA mode and an AP mode coexist, a notification may be sent to the network side in advance, so that the network side obtains the scenario in which the electronic device is to enter a dual-mode coexistence, and the electronic device uses communication sub-channels in different timeslots to respectively interact data in the two modes, at this time, the network side may respectively interact data to the electronic device side through different uplink and downlink timeslots according to preset information for communication sub-channels in different modes.
Therefore, by adopting the scheme, the control information for the communication channel under the coexistence of the STA mode and the AP mode of the NV file can be obtained by loading the NV file, so that the WIFI chip can be in the coexistence of the STA mode and the AP mode. Therefore, the electronic equipment can be used as an access point to access the network and can also be used as an access point to provide the network for other equipment, the working mode of the WIFI chip in the electronic equipment is expanded, and the application scene of the electronic equipment is promoted.
