At present, if the working mode of the wireless fidelity Wi-Fi of the first electronic device is dual band single concurrent (DBSC) mode instead of dual band dual concurrent (DBDC) mode, in some application scenarios, the first electronic device performs 5G band Wi-Fi services and 2.4G band Wi-Fi services by time-sharing transmission, which may easily cause conflicts between the two bands of Wi-Fi services. Therefore, in this application scenario, the first electronic device can only perform 5G band Wi-Fi services, or can only perform 2.4G band Wi-Fi services. Summary of the invention

[0028] The terms used in the following embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to be used as limitations on the present application. As used in the specification and the appended claims of the present application, the singular expressions "one", "a kind of", "said", "above", "the" and "this" are intended to also include plural expressions, unless there is a clear contrary indication in the context. It should also be understood that the term "and / or" used in the present application refers to any or all possible combinations including one or more of the listed striking ones. In the embodiments of the present application, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first" and "second" can expressly or implicitly include one or more of the features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "multiple" is two or more.

[0029] Figure 1 A schematic diagram of the system architecture of a communication system 10 provided in an embodiment of the present application.

[0030] like Figure 1 As shown, the communication system 10 may include: an electronic device 100 (which may be referred to as a first electronic device), an electronic device 200 (which may be referred to as a second electronic device), a wireless access point (AP) device 300, etc. Among them:

[0031] The Wi-Fi working mode on the electronic device 100 can be a dual band single concurrent (DBSC) mode, not a dual band dual concurrent (DBDC) mode. Among them, the DBSC mode means that the electronic device 100 can include 2 complete baseband processing modules and 1 complete radio frequency (RF) front end, and the RF front end can choose to work in the 2.4GHz band (referred to as the 2.4G band) or the 5GHz band (referred to as the 5G band). Although the baseband processing module supports the 2.4GHz band and the 5GHz band respectively, since the RF front end can only stably select one band to work, DBSC can only perform Wi-Fi services in the 2.4GHz band and Wi-Fi services in the 5GHz band through time-sharing transmission. The DBDC mode means that if the electronic device includes 2 complete baseband processing modules and 2 complete RF front ends, the electronic device can simultaneously perform Wi-Fi services in the 2.4GHz band and Wi-Fi services in the 5GHz band.

[0032] The electronic device 100 may establish a wireless communication connection with the AP device 300. In the embodiment of the present application, the wireless communication connection established between the electronic device 100 and the AP device 300 may be a wireless fidelity (Wi-Fi) connection in the 2.4G frequency band.

[0033] The electronic device 100 can establish a wireless communication connection with the electronic device 200. In the embodiment of the present application, the wireless communication connection established between the electronic device 100 and the electronic device 200 can be a 5G band Wi-Fi connection, and a 5G band Wi-Fi service is performed based on the 5G band Wi-Fi connection. Exemplarily, the electronic device 100 can perform network sharing services (also known as Wi-Fi hotspot services) with the electronic device 200, that is, the electronic device 100 converts the received cellular network signal (such as 3G cellular network signal, 4G cellular network signal, etc.) into a Wi-Fi signal and transmits it outward, so that the electronic device 200 can connect to the Wi-Fi signal through the wireless communication module on its own device, and establish a 5G band Wi-Fi connection with the electronic device 100, thereby accessing the Internet; another example is that the electronic device 100 can establish a 5G band WLAN direct connection with the electronic device 200, that is, the electronic device 100 and the electronic device 200 do not need a wireless access point device to establish a 5G band Wi-Fi connection, and based on the WLAN direct connection, perform point-to-point (peer to peer, P2P) data transmission services (for example, screen projection services, keyboard and mouse sharing services, etc.).

[0034] In the embodiment of the present application, Figure 1 This is only an example to explain the present application and does not constitute any limitation to the present application. In other implementations, the AP device 300 may not be a wireless access point device, but an electronic device of the same type as the electronic device 100 and the electronic device 200, and the present application does not limit this.

[0035] Figure 2 A schematic diagram of a wireless fidelity 5 GHz channel distribution provided in an embodiment of the present application.

[0036] like Figure 2 As shown in the figure, in actual applications, if all Wi-Fi devices use the same frequency band, they are prone to mutual interference, so the frequency band needs to be divided into multiple channels (channels can also be called channels, which are data signal transmission channels using electromagnetic waves as transmission carriers) to disperse the devices. The Institute of Electrical and Electronics Engineers has proposed a division standard. Taking China's channel division rules as an example, channels under the 5GHz frequency band can be divided into authorized channels and unauthorized channels. The division results can be seen in Figure 1The bandwidth of each channel is 20MHz. Channels in the 5GHz band also support link bundling, which can bundle 2 or 4 channels into one channel. The bandwidth of the channel after link bundling can be 40MHz or 80MHz, etc. Figure 1 The black blocks shown are unlicensed channels, that is, channels that can be used without obtaining authorization. The frequency range of unlicensed channels includes 5.17 GHz to 5.33 GHz, and the channels in this frequency range are channel 36, channel 40, channel 44, channel 48, channel 52, channel 56, channel 60, and channel 64; the frequency range of unlicensed channels also includes 5.735 GHz to 5.825 GHz, and the available channels in this frequency range are channel 149, channel 153, channel 157, channel 161, and channel 165. Figure 1 The channels in the rest of the frequency range (white blocks) are all authorized channels, that is, channels that can only be used with authorization.

[0037] Among them, unlicensed channels may include open channels (also known as general channels) and radar channels. The frequency range of open channels may include 5.17GHz to 5.25GHz, including channels 36, channel 40, channel 44 and channel 48; the frequency range of open channels may also include 5.735GHz to 5.825GHz, including channels 149, channel 153, channel 157, channel 161 and channel 165. The frequency range of radar channels includes 5.25GHz to 5.33GHz, including channels 52, channel 56, channel 60 and channel 64. Among them, the device that wants to use the radar channel must have a dynamic frequency selection (DFS) function, and the radar channel can only be used after the DFS detection is passed. In an embodiment of the present application, the radar channel may be referred to as a DFS channel.

[0038] In some countries and regions, the division and Figure 1 Differently, the unlicensed channels in the 5 GHz band may also include indoor channels (indoors channel). For example, indoor channels may include channel 36, channel 40, channel 44, channel 48, channel 52, channel 56, channel 60, and channel 64. Since indoor channels may be used by radar signals, etc., the device that uses the indoor channels must have the function of detecting whether the device is located indoors. The indoor channels can only be used after the device detects that it is in an indoor environment. In an embodiment of the present application, the wireless access device can use indoor channels. In some countries and regions, indoor channels in the 5 GHz band may also include radar channels in the 5 GHz band. For example, channels 52 to 64 are both indoor channels and radar channels.

[0039] DFS channels usually give priority to transmitting designated radar signals, such as radar signals emitted by military radars, satellite communications, and weather radars.

[0040] When the DFS channel is transmitting a radar signal, the electronic device 100 and the electronic device 200 should remain silent on the DFS channel and cannot transmit a 5G band Wi-Fi signal on the DFS channel. When the DFS channel is not transmitting a radar signal, the electronic device 100 and the electronic device 200 can use the DFS channel to transmit a 5G band Wi-Fi signal.

[0041] Therefore, if the electronic device 100 and the electronic device 200 use the radar channel to transmit the Wi-Fi signal in the 5G frequency band, the radar signal detection and power control are required. The electronic device 100 and the electronic device 200 can detect the radar signal through the Channel Availability Check process (CAC) to avoid electromagnetic interference to the radar signal when using the DFS channel. Among them, taking the electronic device 100 as an example, the parameter conditions involved in the radar signal detection must meet the regulations, as shown in the following Table 1:

[0042] Table 1

[0043]

[0044] As shown in Table 1, the channel validity detection time is 60 seconds, that is, the electronic device 100 detects the radar signal on the DFS channel for 60 seconds; the channel migration time is 10 seconds, that is, the timing starts when the radar signal on the DFS channel stops sending, and the electronic device 100 should stop transmitting signals on the DFS channel within 10 seconds; the channel closing transmission time is 1 second, that is, from the time when the radar signal stops sending, the total time that the electronic device 100 transmits signals on the DFS channel cannot exceed 1 second; the non-occupancy period is 30 minutes, that is, after the electronic device 100 detects the radar signal on the DFS channel, it cannot transmit signals on the DFS channel within 30 minutes.

[0045] In the embodiment of the present application, the values ​​of the parameters in Table 1 are only examples. In other implementations, the parameters may also have values ​​different from those in Table 1, and the present application does not impose any limitation on this.

[0046] Figure 3 A schematic diagram of a wireless communication connection scenario provided in an embodiment of the present application.

[0047] like Figure 3As shown in (a), the electronic device 100 and the electronic device 200 can establish a 5G band Wi-Fi connection on the DFS channel. At this time, the electronic device 100 and the electronic device 200 can transmit signals on the DFS channel. If the electronic device 100 or the electronic device 200 needs to transmit a 5G band Wi-Fi signal on the DFS channel, the transmitting end (i.e., the electronic device sending data, which can be the electronic device 100 or the electronic device 200) needs to perform radar signal detection on the DFS channel, and the parameter conditions involved in the radar signal detection need to meet the examples in Table 1.

[0048] like Figure 3 As shown in (b), after the electronic device 100 and the electronic device 200 establish a 5G band Wi-Fi connection on the DFS channel, if at this time, the electronic device 100 and the AP device 300 establish a 2.4G band Wi-Fi connection, the electronic device 100 needs to transmit the 2.4G band Wi-Fi signal and the 5G band Wi-Fi signal in a time-sharing manner. For example, the electronic device transmits the 2.4G band Wi-Fi signal at time T1 and transmits the 5G band Wi-Fi signal at time T2, and time T1 and time T2 are not the same time. The electronic device 100 transmits a Wi-Fi signal in the 2.4G band and needs to switch to a Wi-Fi channel in the 2.4G band. In this case, the electronic device 100 cannot detect the radar signal on the DFS channel and therefore cannot meet the above-specified parameter conditions. Therefore, in some application scenarios, if the electronic device 100 and the electronic device 200 establish a Wi-Fi connection in the 5G band on the DFS channel, the electronic device 100 and the AP device 300 are not allowed to establish a Wi-Fi connection in the 2.4G band.

[0049] Exemplarily, if the electronic device 100 transmits a 2.4G band Wi-Fi signal on a 2.4G band Wi-Fi channel at time T3, and there is a radar signal on the DFS channel at this time, the electronic device 100 cannot detect the radar signal at time T3. At time T4, the electronic device 100 switches back to the DFS channel to send a 5G band Wi-Fi signal, and it is necessary to detect the radar signal for 60 seconds. In general, the 2.4G band Wi-Fi signal and the 5G band Wi-Fi signal switch frequently. If each time the DFS channel is switched back to send a 5G band Wi-Fi signal, it is necessary to detect the radar signal for 60 seconds, then the data transmission delay of the electronic device 100 will be longer, and the time overhead will be greatly increased. Therefore, in some application scenarios, if the electronic device 100 and the electronic device 200 establish a 5G band Wi-Fi connection on the DFS channel, it is not allowed to establish a 2.4G band Wi-Fi connection with the AP device 300.

[0050] Therefore, the present application provides a wireless communication method, which includes: when the electronic device 100 and the electronic device 200 establish a Wi-Fi connection on the 5G frequency band, the electronic device 100 can use the DFS channel to transmit data with the electronic device 200; when the electronic device 100 and the electronic device 200 establish a Wi-Fi connection on the 5G frequency band, and the electronic device 100 and the AP device 300 establish a Wi-Fi connection on the 2.4G frequency band, the electronic device 100 sends data to the electronic device 200 through a non-DFS channel. Alternatively, the electronic device 100 and the electronic device 200 establish a Wi-Fi connection on the 5G frequency band on the non-DFS channel.

[0051] Embodiment This wireless communication method can achieve that after the electronic device 100 and the electronic device 200 establish a 5G band Wi-Fi connection on the DFS channel, the electronic device 100 can still establish a 2.4G band Wi-Fi connection with the AP device 300. In this way, the electronic device 100 can perform different services with different electronic devices through the 2.4G band Wi-Fi connection and the 5G band Wi-Fi connection, which expands the use scenarios of the electronic device 100 and improves the business processing efficiency of the electronic device 100.

[0052] Figure 4 A schematic diagram of a specific flow chart of a wireless communication method provided in an embodiment of the present application.

[0053] like Figure 4 As shown, the specific process of the wireless communication method may include:

[0054] S401: The electronic device 100 and the electronic device 200 establish a Wi-Fi connection on the 5G frequency band on the DFS channel.

[0055] The Wi-Fi connection of the 5G frequency band may also be referred to as the first Wi-Fi connection. In this process, the DFS channel may be referred to as the second channel.

[0056] In some application scenarios, the DFS channel may be a channel with a bandwidth of 80 MHz formed by bundling channels 52 to 64.

[0057] S402: The electronic device 100 and the electronic device 200 transmit data using the DFS channel.

[0058] At this time, the electronic device 100 may use the DFS channel to send data to the electronic device 200 , and may also use the DFS channel to receive data sent by the electronic device 200 .

[0059] S403: The electronic device 100 and the AP device 300 establish a Wi-Fi connection on the 2.4G frequency band.

[0060] The Wi-Fi connection in the 2.4 GHz frequency band may also be referred to as a second Wi-Fi connection.

[0061] S404: The electronic device 100 determines that the electronic device 100 and the electronic device 200 switch the channel of the 5G band Wi-Fi connection from the DFS channel to the non-DFS channel.

[0062] The non-DFS channel is a channel that does not include a radar channel. In this process, the non-DFS channel may also be referred to as a first channel.

[0063] Exemplarily, the non-DFS channel may be a channel with 80Mhz bandwidth with channel 36 as the primary channel (such as a channel formed by bundling channels 36 to 48), or a channel with 80Mhz bandwidth with channel 149 as the primary channel (such as a channel formed by bundling channels 149 to 161). In the channel with 80Mhz bandwidth, channels other than the primary channel are called slave channels or auxiliary channels (for example, channel 40, channel 44, channel 48, or channel 153, channel 157, channel 161). The primary channel is used to send management frames and control frames, and the slave channel is used to send data frames.

[0064] S405: The electronic device 100 sends a first beacon frame, wherein the first beacon frame is used to trigger the electronic device 200 to switch the channel of the 5G band Wi-Fi connection from the DFS channel to the non-DFS channel.

[0065] Specifically, the electronic device 100 may switch the channel of the 5G band Wi-Fi connection from the DFS channel to the non-DFS channel, and through a channel switch announcement (CSA), the electronic device 200 also switches the channel of the 5G band Wi-Fi connection from the DFS channel to the non-DFS channel. The electronic device 100 may send a first beacon frame to trigger the electronic device 200 to switch the channel of the 5G band Wi-Fi connection from the DFS channel to the non-DFS channel.

[0066] Among them, Figure 5As shown, the first beacon frame (Beacon) may include: an extended channel change announcement information element (also called ECSA cell, extendedchannelswitchannouncementelementformat), a channel change envelope information element (also called CSW cell, channelswitchelementformat), and the CSW cell may include a bandwidth channel change sub-element (also called WBCS cell, widebandwidthchannelswitchelementformat), etc. Specifically:

[0067] 1. The ECSA cell may include: an element identifier (Element ID), which is 1 byte in length and is used to indicate that the cell is an ECSA cell; an element length (Length), which is 1 byte in length and is used to indicate the total length of the ECSA cell; a channel switch mode (Channel Switch Mode), which is 1 byte in length and is used to indicate any restrictions on the transmission mode before the channel switch; a new operating class field (New Operating Class), which is 1 byte in length and is set to the operating class number after the channel switch, and is used to indicate the operation type after the channel switch; a new channel number (New Channel Number), which is 1 byte in length and is used to indicate the number of the new channel after the channel switch (the new channel in the embodiment of the present application is the non-DFS channel after the switch); a channel switch count (Channel Switch Count), which is 1 byte in length and is used to indicate the time when the channel switch occurs.

[0068] 2. The CSW cell may include: an element identifier (Element ID), which is 1 byte long and is used to indicate that the cell is a CSW cell; an element length (Length), which is 1 byte long and is used to indicate the total length of the CSW cell; a new country subelement (NewCountry subelement), which is of variable length and is used to indicate the country, operation type, etc. of the base station subsystem BSS after the channel switch; a bandwidth channel change subelement (Wide BandwidthChannel Switch subelement), which is of variable length and is used to indicate information such as the bandwidth of the new channel; a new transmit power envelope subelement (New Transmit Power Envelope subelement), which is of variable length and indicates the power parameters used for the BSS after the channel switch.

[0069] 3. The WBCS cell may include: an element identifier (Element ID), which is 1 byte in length and is used to indicate that the cell is a WBCS cell; an element length (Length), which is 1 byte in length and is used to indicate the total length of the WBCS cell; a new channel bandwidth (NewChannelWidth), which is 1 byte in length and is used to indicate the bandwidth of the new channel; New ChannelCenterFrequencySegment0 and New ChannelCenterFrequencySegment1, which are both 1 byte in length and are used to indicate the center frequency segment of the new channel.

[0070] S406: The electronic device 100 sends data to the electronic device 200 using the non-DFS channel.

[0071] In the embodiment of the present application, since the electronic device 100 uses the non-DFS channel to send data to the electronic device 200 at this time, the electronic device 100 no longer needs to detect the radar signal on the DFS channel. The electronic device 100 can connect to different electronic devices through the Wi-Fi connection of the 2.4G frequency band and the Wi-Fi connection of the 5G frequency band to perform different services, which expands the use scenarios of the electronic device 100 and improves the service processing efficiency of the electronic device 100.

[0072] In some implementations, if in step S401, the electronic device 100 and the electronic device 200 establish a Wi-Fi connection on the 5G band on channel A including but not limited to a DFS channel (i.e., channel A is a combination of a DFS channel and a non-DFS channel), when the electronic device 100 and the AP device 300 establish a Wi-Fi connection on the 2.4G band, the electronic device 100 may also implement Figure 4 For example, if the electronic device 100 and the electronic device 200 establish a 5G band Wi-Fi connection on a 160 MHz bandwidth channel that is composed of channel 36 as the main channel, channels 36 to 48 (non-DFS channels) and channels 52 to 64 (DFS channels), when the electronic device 100 and the AP device 300 establish a 2.4 GHz band Wi-Fi connection, the electronic device 100 can also implement Figure 4 The described method enables the electronic device 100 and the electronic device 200 to migrate the Wi-Fi connection of the 5G band from the 160 MHz bandwidth channel bundled by channels 36 to 48 and channels 52 to 64 to other 160 MHz bandwidth channels that do not include DFS channels.

[0074] like Figure 6 As shown, the specific process of the wireless communication method may include:

[0075] S601: The electronic device 100 and the electronic device 200 establish a Wi-Fi connection on the 5G frequency band on channel 1. Channel 1 may include a DFS channel and a non-DFS channel.

[0076] The Wi-Fi connection of the 5G frequency band may also be referred to as the first Wi-Fi connection. In this process, channel 1 may be referred to as the second channel, and the non-DFS channel in channel 1 may be referred to as the first channel.

[0077] Specifically, channel 1 may include a DFS channel and a non-DFS channel, that is, channel 1 is formed by bundling DFS channels and non-DFS channels, but the main channel of channel 1 is included in the non-DFS channels. For example, channel 1 may be a 160 MHz bandwidth channel formed by bundling channel 36 as the main channel, channels 36 to 48 (non-DFS channels) and channels 52 to 64 (DFS channels).

[0078] S602: Electronic device 100 and electronic device 200 use channel 1 to transmit data.

[0079] At this time, the electronic device 100 can use the DFS channel and / or the non-DFS channel in channel 1 to send data to the electronic device 200, and can also use the DFS channel and / or the non-DFS channel in channel 1 to receive data sent by the electronic device 200. At this time, the transmitting end (that is, the electronic device that sends data, which can be the electronic device 100 or the electronic device 200) needs to detect the radar signal on the DFS channel.

[0080] S603: The electronic device 100 and the AP device 300 establish a Wi-Fi connection on the 2.4G frequency band.

[0081] The Wi-Fi connection in the 2.4 GHz frequency band may also be referred to as a second Wi-Fi connection.

[0082] S604: The electronic device 100 sends data to the electronic device 200 through the non-DFS channel in channel 1.

[0083] At this time, the electronic device 100 establishes a Wi-Fi connection on the 5G band with the electronic device 200, and establishes a Wi-Fi connection on the 2.4G band with the AP device 300. In order to avoid the problem that the electronic device 100 cannot detect the radar signal when transmitting the Wi-Fi signal on the 2.4G band, resulting in the electronic device 100 switching back to channel 1 and selecting the DFS channel to send the Wi-Fi signal on the 5G band, thereby interfering with the radar signal, in this scenario, the electronic device 100 sends data to the electronic device 200 through the non-DFS channel in channel 1.

[0084] Specifically, the electronic device 100 may send a physical frame 1 to the electronic device 200 through a non-DFS channel in channel 1, and the physical frame 1 (which may be referred to as a first physical frame) may include an identifier 1 (which may be referred to as a first identifier) ​​and data, and the identifier 1 may be used to indicate that the electronic device 100 uses the non-DFS channel in channel 1 to send the data in the physical frame 1. Exemplarily, the physical frame 1 may be a HE SU PPDU, and the identifier 1 may be located in a HE-SIG-A field in the HE SU PPDU.

[0085] In different application scenarios, the identifier 1 may be located in different fields in the physical frame 1, as shown in Table 2, Table 3, and Table 4:

[0086] Table 2

[0087]

[0088] As can be seen from Table 2, the identifier 1 may be located in the VHT-SIG-A field, occupying bytes B0-B1, having a length of 2 bytes, and the set value 0 represents a channel bandwidth of 20 MHz, 1 represents a channel bandwidth of 40 MHz, 2 represents a channel bandwidth of 80 MHz, and 3 represents a channel bandwidth of 160 MHz and 80+80 MHz.

[0089] Table 3

[0090]

[0091]

[0092] As can be seen from Table 3, identifier 1 can be located in the HE-SIG-A field, occupying B19-B20 bytes and having a length of 2 bytes. In the HE SU PPDU, the set value 0 represents a channel bandwidth of 20MHz, 1 represents a channel bandwidth of 40MHz, 2 represents a channel bandwidth of 80MHz, and 3 represents a channel bandwidth of 160MHz and 80+80MHz; in the HE ER SU PPDU, if it is a 242-toneRU (that is, a resource unit consists of 242 subcarriers), it is set to 0; if it is a 106-tone RU (a resource unit consists of 106 subcarriers) with a higher frequency within the main frequency of 20MHz, it is set to 1.

[0093] Table 4

[0094]

[0095]

[0096] As can be seen from Table 4, the identifier 1 can be the U-SIG-1 part located in the U-SIG field, occupying bytes B3-B5, with a length of 3 bytes, and setting 0 to represent 20MHz, 1 to represent 40MHz, 2 to represent 80MHz, 3 to represent 160MHz, 4 to represent 320MHz-1, 5 to represent 320MHz-2, and 6 and 7 to be verification values. Among them, 320MHz-1 represents a channel with a center frequency of 31MHz, 95MHz and 195MHz and a bandwidth of 320MHz, and 320MHz-1 represents a channel with a center frequency of 63MHz, 127MHz and 191MHz and a bandwidth of 320MHz.

[0097] From the identifier 1 shown in Table 2, Table 3 and Table 4 above, it can be seen that in the example of the embodiment of the present application, the identifier 1 directly identifies the bandwidth of the channel. Generally, taking channel 1 as a 160MHz bandwidth channel formed by bundling channel 36 to channel 48 (non-DFS channels) and channel 52 to channel 64 (DFS channels), the value of identifier 1 can be set to 2 based on the example of Table 2, the value of identifier 1 can be set to 2 based on the example of Table 3, and the value of identifier 1 can be set to 2 based on the example of Table 4, indicating that the electronic device 100 sends data to the electronic device 200 through the channel with an 80MHz bandwidth. However, since the channel used by the electronic device must include the main channel, the 80MHz channel must include channel 36 (main channel), that is, the 80MHz bandwidth channel is formed by bundling channels 36 to channel 48 (non-DFS channels), so the identifier 1 can indicate that the electronic device 100 sends data to the electronic device 200 through the non-DFS channel in channel 1.

[0098] S605: The electronic device 100 receives data sent by the electronic device 200 through the channel 1.

[0099] In this scenario, although the electronic device 100 sends data to the electronic device 200 through the non-DFS channel in channel 1, the electronic device 100 can receive the data sent by the electronic device 200 through all channels included in channel 1. At this time, the electronic device 100 does not detect the radar signal in the DFS channel, while the electronic device 200 detects the radar signal in the DFS channel.

[0100] In the examples of the present application, Table 2, Table 3 and Table 4 are only used to exemplify the present application and do not constitute any limitation.

[0101] Figure 7 A schematic diagram of a specific process of another wireless communication method provided in an embodiment of the present application.

[0102] like Figure 7 As shown, the specific process of the wireless communication method may include:

[0103] S701: The electronic device 100 scans one or more Wi-Fi channels in the 5G frequency band.

[0104] The one or more Wi-Fi channels of the 5G frequency band may include: one or more non-DFS channels and DFS channels. The description of the non-DFS channels and the DFS channels may refer to the aforementioned embodiments.

[0105] S702: The electronic device 100 establishes a 5G band Wi-Fi connection with the electronic device 200 on channel 3. Channel 3 is a non-DFS channel.

[0106] Specifically, in one implementation, the electronic device 100 may record one or more scanned Wi-Fi channels of the 5G frequency band as a first record table, and then the electronic device 100 selects a non-DFS channel (e.g., channel 3) with the lowest signal interference / highest signal strength in the first record table to establish a 5G frequency band Wi-Fi connection with the electronic device 200. In this process, channel 3 may be referred to as the first channel.

[0107] In another implementation, the electronic device 100 may record the non-DFS channels among the scanned one or more 5G band Wi-Fi channels as a first record table. Then, the electronic device 100 selects the channel with the lowest signal interference / highest signal strength in the first record table (for example, channel 3) to establish a 5G band Wi-Fi connection with the electronic device 200.

[0108] S703: The electronic device 100 and the AP device 300 establish a Wi-Fi connection on the 2.4G frequency band.

[0109] The Wi-Fi connection in the 2.4 GHz frequency band may also be referred to as a second Wi-Fi connection.

[0110] S704: Electronic device 100 transmits data to electronic device 200 via channel 3.

[0111] Since the electronic device 100 establishes a 5G band Wi-Fi connection with the electronic device 200 on a non-DFS channel and does not need to detect radar signals on the DFS channel, the establishment of a 2.4G band Wi-Fi connection between the electronic device 100 and the AP device 300 does not affect the Wi-Fi service between the electronic device 100 and the electronic device 200.

[0112] In some implementations, optionally, when the electronic device 100 and the AP device 300 establish a Wi-Fi connection in the 2.4G frequency band, the electronic device 100 can determine whether the electronic device 100 supports DBDC. Specifically, if the electronic device 100 reads the identifier 2 corresponding to DBDC, it is determined that the electronic device 100 supports DBDC. If the electronic device 100 reads the identifier 3 corresponding to DBSC, it is determined that the electronic device 100 does not support DBDC but DBSC. If the electronic device 100 does not support DBDC, the electronic device 100 can implement the above Figure 4 , Figure 6 or Figure 7 The process described; if the electronic device 100 supports DBDC, the electronic device 100 can simultaneously perform 2.4G band Wi-Fi services and 5G band Wi-Fi services. At this time, the electronic device 100 and the electronic device 200 can still transmit data through the DFS channel.

[0113] In some implementations, the electronic device 100 may first establish a 2.4G band Wi-Fi connection with the AP device 300, and then establish a 5G band Wi-Fi connection with the electronic device 200. At this time, the electronic device 100 and the electronic device 200 may implement Figure 7 Among S701~S702 and S704.

[0114] Figure 8 Schematic diagram of the hardware structure of an electronic device 100 provided in an embodiment of the present application.

The memory may store instructions or data that the processor 801 has just used or circulated. If the processor 801 needs to use the instruction or data again, it may be directly called from the memory. This avoids repeated access, reduces the waiting time of the processor 801, and thus improves the efficiency of the system.

The photosensitive element can be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, and then passes the electrical signal to the ISP to be converted into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV or other format. In some embodiments, the electronic device 100 may include 1 or N cameras 805, where N is a positive integer greater than 1.

In some embodiments, the audio module 806 can also be arranged in the processor 801, or some functional modules of the audio module 806 can be arranged in the processor 801.

[0126] Microphone 807, which can also be called "microphone" or "microphone", can be used to collect sound signals in the environment surrounding the electronic device, convert the sound signals into electrical signals, and then subject the electrical signals to a series of processing, such as analog-to-digital conversion, to obtain an audio signal in digital form that can be processed by the processor 801 of the electronic device. When making a call or sending a voice message, the user can speak by approaching the microphone 807 with his mouth to input the sound signal into the microphone 807.

The RF front end can choose to work in the 2.4GHz frequency band (referred to as the 2.4G frequency band) or in the 5GHz frequency band (referred to as the 5G frequency band). Although the baseband processing module 1 and the baseband processing module 2 support the 2.4GHz frequency band and the 5GHz frequency band respectively, since the RF front end can only stably select one frequency band to work, the Wi-Fi device can only receive / send Wi-Fi signals in the 2.4GHz frequency band and Wi-Fi signals in the 5GHz frequency band through time-sharing transmission.
