[0036] At present, various countries or regions have set up corresponding electromagnetic wave frequency bands for industrial, scientific and medical fields, which are called ISM bands (Industrial Scientific Medical Bands). The ISM band is an unlicensed or license-free band, and it is not necessary to apply for a license from a specialized agency to use it.

[0037] Given the unlicensed use of the ISM band, other non-Wi-Fi communication technology products also use the same ISM band, such as Bluetooth devices, ZigBee devices, cordless phones, microwave ovens, etc. Therefore, when Wi-Fi technology was first used, there was a possibility of conflict with spectrum resources of other wireless products.

[0038] The types and number of Wi-Fi products are growing rapidly, and unlicensed frequency bands are one of the key factors. However, after the large-scale popularization of Wi-Fi, the use of wireless resources in unlicensed frequency bands by devices has caused more and more conflicts, and the signal interference between devices has become a constraint on the application of Wi-Fi technology in scenarios. Therefore, how to reduce signal interference when devices use Wi-Fi communication has become a technical problem that needs to be solved urgently in this field.

[0039] Based on this, the embodiments of the present application provide an information sending method, an information receiving method, a device, and a storage medium, which can reduce signal interference when the device uses Wi-Fi communication.

[0040] The information sending method and information receiving method provided in the present application can be applied to a wireless communication system, and the wireless communication network may include a wireless local area network (WLAN) or a cellular mobile communication network, etc. The method can be implemented by a communication device in the wireless communication system or a logic circuit or processor in the communication device.

[0046] The present application embodiment first proposes a method for sending information. Figure 2 , Figure 2 A method for sending information provided by an embodiment of the present application is shown. Figure 2 As shown, the method includes but is not limited to step S110 and step S120.

[0047] Step S110: The first device obtains characteristic information of the non-Wi-Fi signal.

[0048] It should be understood that non-Wi-Fi signals refer to wireless communication signals other than Wi-Fi signals, and specifically may be wireless communication signals that use the same frequency band as Wi-Fi signals, such as Bluetooth signals, Direct Sequence Spread Spectrum (DSSS) signals, analog signals, etc. The characteristic information of non-Wi-Fi signals refers to various signal characteristics of non-Wi-Fi signals, and specifically may be characteristic information used to describe the performance, coverage, or connection quality of Wi-Fi signals, such as duration, signal strength, working channel, etc.

[0049] Step S120: The first device sends a first frame to the second device, where the first frame carries characteristic information of the non-Wi-Fi signal, so that the second device performs channel configuration related operations according to the characteristic information of the non-Wi-Fi signal.

[0050] It can be understood that the first device sends the characteristic information carrying the non-Wi-Fi signal to the second device, so that the second device can perform channel configuration related operations according to the characteristic information of the non-Wi-Fi signal. For example, the second device selects a working channel with reference to the characteristic information of the non-Wi-Fi signal, thereby avoiding the working channel of the non-Wi-Fi signal or the surrounding channels affected by the non-Wi-Fi signal.

[0051] In the embodiment of the present application, the first device obtains characteristic information of the non-Wi-Fi signal, and then the first device sends the characteristic information carrying the non-Wi-Fi signal to the second device, the second device receives the characteristic information carrying the non-Wi-Fi signal sent by the first device, and then the second device performs channel configuration related operations according to the characteristic information of the non-Wi-Fi signal, which can reduce signal interference when the device uses Wi-Fi communication, reduce the data transmission delay of the device, improve the stability of data transmission, and improve channel utilization.

[0052] In some embodiments, the characteristic information of the non-Wi-Fi signal includes at least one of the following: time domain characteristic information, frequency domain characteristic information, or non-Wi-Fi signal type information; wherein,

[0053] The time domain characteristic information includes at least one of the following: signal period characteristic information or signal duration information.

[0054] The frequency domain characteristic information includes at least one of the following: signal transmission power information, received signal strength information, signal working channel category information, signal working channel number information, surrounding channel number information affected by the signal, or signal bandwidth information.

[0055] The non-Wi-Fi signal type information includes at least one of the following: signal type information or signal name information.

[0056] It should be understood that the characteristic information of the non-Wi-Fi signal may include the time domain characteristic information of the signal. From the time domain aspect, the non-Wi-Fi signal can be divided into a periodic signal and a non-periodic signal. A periodic signal refers to a signal with a fixed access time and period. For example, a Bluetooth signal belongs to a periodic signal, and its access period may be 3.75ms or 7.5ms. A non-periodic signal refers to a signal with a non-fixed access time or period. For example, a microwave signal generated by a microwave oven belongs to a non-periodic signal. When the microwave oven is working, the microwave signal generated by the microwave oven will occupy the signal until it stops working. Therefore, the time domain characteristics of the signal can be described by the signal period characteristic information or the signal duration information, so that the second device can use the time domain characteristic information of the signal to perform channel configuration related operations, and can perform channel avoidance and other related operations from a time perspective to reduce the signal interference of the non-Wi-Fi signal to the device using the Wi-Fi communication technology.

[0057] It should be understood that the characteristic information of the non-Wi-Fi signal may also include the frequency domain characteristic information of the signal. Specifically, the frequency domain characteristic information may include the following: the signal transmission power information, the received signal strength information, the signal working channel category information, the signal working channel number information, the surrounding channel number information affected by the signal, or the signal bandwidth information.

[0058] It should be noted that the signal transmission power information is an indicator used to measure the power used by the wireless communication device when transmitting the radio frequency signal, and is usually expressed in decibel milliwatts dBm. For example, when the first device acts as the transmitter of the non-Wi-Fi signal, the transmission power information of the non-Wi-Fi signal can be reported to the second device; the received signal strength information is an indicator used to measure the strength of the received radio frequency signal, and is usually expressed in decibel milliwatts dBm. For example, the first device obtains the non-Wi-Fi signal through spectrum scanning, that is, the second device can act as the receiver of the non-Wi-Fi signal, obtain the received signal strength information of the non-Wi-Fi signal by calculation, and report the received signal strength information to the second device.

[0059] On the one hand, from the aspect of signal strength, non-Wi-Fi signals are divided into strong signals and weak signals. Taking the threshold value of Wi-Fi signals as (-82dBm, -62dBm) as an example, when the signal strength of the interference signal is less than the lowest threshold value, that is, less than -82dBm, the Wi-Fi device is less interfered by the signal. When the signal strength of the interference signal is within the threshold value, the Wi-Fi device can still access the channel. However, when the signal strength of the interference signal is greater than the highest threshold value, that is, greater than -62dBm, the Wi-Fi device will be seriously interfered by the signal and can hardly access the channel. Therefore, the signal strength characteristics of the signal can be described by the signal transmission power information or the received signal strength information, so that the second device can use the signal strength characteristics of the signal to perform channel configuration related operations, and can perform channel avoidance and other related operations from the aspect of signal strength to reduce the signal interference of non-Wi-Fi signals to devices using Wi-Fi communication technology.

[0060] It should be noted that the working channel category information refers to the frequency band or frequency range in which the signal works, such as the 2.4GHz band, the 5GHz band, and the 6GHz band; the working channel number refers to the channel number in which the signal works in the corresponding frequency band. For example, the 2.4GHz band is usually divided into 14 channels, and the 14 channels correspond to channel numbers 1 to 14. That is to say, if the working channel type of the signal is the 2.4GHz band, then its working channel number is at least one of the channel numbers 1 to 14. In addition, the operating frequency range of the 2.4GHz band is 2.402GHz to 2.483Ghz, where the bandwidth of each channel is 22MHz, the center frequency of each channel increases in multiples of 5MHz, the effective bandwidth is 20MHz, and the remaining 2MHz belongs to the isolation protection bandwidth. In the entire 2.4GHz band, only channels 1, 6, and 11 do not overlap each other, that is, channels other than channels 1, 6, and 11 in the 2.4GHz band will interfere with their adjacent channels. Therefore, it can be described by the surrounding channel coding information affected by the signal. For example, if a non-Wi-Fi signal works on channel 8 of the 2.4GHz band, the surrounding signal channel coding information affected by the signal is 7 and 9; the signal bandwidth information refers to the spectrum range occupied by the signal, usually expressed in Hertz Hz. For example, the channel bandwidth of a Bluetooth signal is 1MHz, and 4G LTE uses a bandwidth of 5MHz, 10MHz, or 20MHz.

[0061] On the other hand, from the frequency domain, non-Wi-Fi signals can be divided into broadband signals and narrowband signals. Broadband signals refer to signals operating in a wider frequency band, such as signals generated by Bluetooth devices and microwave ovens operating in the entire 2.4 GHz frequency band, and narrowband signals refer to signals operating in a narrower frequency band, such as signals generated by analog cordless phones operating only on channels 1, 2, and 3 of the corresponding frequency band, and signals generated by direct sequence spread spectrum (DSSS) phones operating only on channel 165 of the corresponding frequency band. Therefore, the frequency domain characteristics of the signal can be described by the signal's operating channel category information, the signal's operating channel number information, the surrounding channel number information affected by the signal, or the signal's bandwidth information, so that the second device can use the signal's frequency domain characteristic information to perform channel configuration related operations, and can perform channel avoidance and other related operations from a frequency domain perspective to reduce the signal interference of non-Wi-Fi signals on devices using Wi-Fi communication technology.

[0062] It should be understood that the non-Wi-Fi signal type information may also include non-Wi-Fi signal type information, specifically, the non-Wi-Fi signal type information includes signal type information or signal name information. The signal type information is the type of the non-Wi-Fi signal, such as a Bluetooth signal, a direct sequence spread spectrum signal, or an analog signal, and the signal name information is the specific name of the non-Wi-Fi signal.

[0063] In a specific embodiment, see Figure 7 , Figure 7 FIG. 4 shows a schematic diagram of a field format of characteristic information of a non-Wi-Fi signal provided in an embodiment of the present application, such as Figure 7 As shown, the first frame sent by the first device to the second device includes fields: period period, duration duration, transmit power TX power (Transmit Power), received signal strength RSSI (Received Signal Strength Indicator), operating channel type Operating class, operating channel Operating channel, affected channel Affected channel, bandwidth Bandwidth, type Type and name Name, which are respectively used to carry signal period characteristic information, signal duration information, transmit power information, signal strength information, operating channel category information, operating channel number information, surrounding channel number affected by the signal, bandwidth information, signal type information and signal name information of the non-Wi-Fi signal. The first device transmits the signal to the second device in the first frame as shown in FIG. Figure 7 The field shown carries characteristic information of the non-Wi-Fi signal, and sends the first frame to the second device, so that the second device can analyze the non-Wi-Fi signal based on the characteristic information in three dimensions of time domain, frequency domain and signal strength and further decide on a way to access the channel, thereby reducing interference of the non-Wi-Fi signal on the Wi-Fi signal transmitted by the device, reducing the data transmission delay of the device, and improving the data transmission stability and channel utilization of the device.

[0064] It should also be noted that the above embodiment describes the information specifically included in the characteristic information of the non-Wi-Fi signal, namely, signal period characteristic information, signal duration information, signal transmission power information, received signal strength information, signal working channel category information, signal working channel number information, signal affected surrounding channel number information, signal bandwidth information, signal type information or signal name information. In actual application, the first device may use the corresponding field in the transmission frame to carry one or more of the above characteristic information, or other characteristic information other than the above examples according to other negotiation regulations, and the embodiments of the present application are not limited here.

[0065] In some embodiments, the first frame is one of: a beacon frame, a probe response frame, a multilink probe response frame, an association request frame, a reassociation request frame, an association response frame, a reassociation response frame, an authentication frame, or an action frame.

[0066] It is understandable that Wi-Fi communication technology is based on the IEEE 802.11 standard protocol series. In the 802.11 standard protocol series, all transmission frames are divided into data frames, control frames and management frames. Among them, management frames are mainly responsible for supervising and managing joining or exiting the wireless network and maintaining communication between access points and stations.

[0067] The following describes the frame types included in the management frame, wherein the AP may be an access point AP, a multilink access point APMLD, or an affiliated access point (affiliated AP) of an AP MLD, and the STA may be a station STA, a multilink station non-APMLD, or an affiliated station of a non-AP MLD:

[0068] Beacon frame: The beacon frame is sent by the AP providing the service to announce the existence of the basic service set (BSS). The beacon frame carries the basic information of the BSS, such as the basic service set identifier (BSSID), service set identifier (SSID), channel, frequency, signal strength, country code, etc.

[0069] Probe Request: A probe request frame is sent by a STA to an AP to detect surrounding BSSs. If the request frame specifies an SSID, the APs in the BSS that have the same SSID as the requested SSID respond with a probe response frame. If the request frame does not specify an SSID, all APs in the BSS respond.

[0070] Probe Response frame: The AP responds to the probe request frame sent by the STA with a probe response frame.

[0071] Multi-link Probe Request: The probe request frame is sent by the STA to the AP to detect the surrounding AP MLD.

[0072] Multi-link Probe Response frame: AP MLD responds to the multi-link probe request frame sent by the STA with a multi-link probe response frame.

[0073] Association Request: After the STA finds the AP and passes the authentication, the STA sends an Association Request to the AP to request the AP to associate. The Association Request carries the basic information of the STA.

[0074] Association Response frame: The AP responds to the association request frame sent by the STA with an association response frame.

[0075] Reassociation Request: When a STA moves away from the original AP and finds a new AP with a stronger signal in the same ESS, the STA sends a reassociation request frame to the new AP.

[0076] Reassociation Response frame: The AP responds to the reassociation request frame sent by the STA with a reassociation response frame.

[0077] Disassociation Frame: The Disassociation Frame is sent by the STA to the AP to terminate the association with the AP.

[0078] Authentication Frame: STA sends an authentication frame to AP. AP performs authentication based on the password entered and sends the authentication result to STA.

[0079] Deauthentication Frame: The deauthentication frame is used to terminate the authentication relationship. Specifically, the STA sends a deauthentication frame to the AP to actively forget the SSID, or the AP sends a deauthentication frame to the STA to actively propose to terminate the connection with the STA.

[0080] Action Frame: STA sends an action frame to AP to request AP to perform a specific operation.

[0081] Therefore, when the first device is an AP device, the first device may use an idle field in a beacon frame, a probe response frame, a multilink probe response frame, an association response frame, a reassociation response frame, or a deauthentication frame to carry characteristic information of a non-Wi-Fi signal; when the first device is a STA device, the first device may use an idle field in an authentication frame, a probe request frame, a multilink probe request frame, a reassociation request frame, a disassociation frame, a deauthentication frame, or an action frame to carry characteristic information of a non-Wi-Fi signal.

[0082] It should be noted that the above embodiment describes the protocol format of the first frame sent by the first device, that is, the first frame can be a management frame in the 802.11 standard protocol, such as a beacon frame, a probe request frame, a probe response frame, a multi-link probe request frame, a multi-link probe response frame, an association request frame, an association response frame, a re-association request frame, a re-association response frame, a disassociation frame, an authentication frame, a deauthentication frame or an action frame. In actual applications, the first device can also use data frames or control frames defined in the 802.11 standard protocol, or use frames defined in other standard protocols to carry characteristic information of non-Wi-Fi signals, which is not limited in the embodiments of the present application.

[0083] In some embodiments, the information sending method further includes at least one of the following steps:

[0084] The first device sends a second frame to the second device, where the second frame carries the non-Wi-Fi signal characteristic capability information of the first device.

[0085] The first device receives a third frame sent by the second device, where the third frame carries the non-Wi-Fi signal characteristic capability information of the second device.

[0086] It can be understood that the first device may choose to send a second frame carrying its own non-Wi-Fi signal characteristic capability information to the second device to inform the second device of its own non-Wi-Fi signal characteristic capability, and the second device may also choose to send a third frame carrying its own non-Wi-Fi signal characteristic capability information to the second device to inform the first device of its own non-Wi-Fi signal characteristic capability. That is, in a wireless communication system, each wireless communication device may send its own non-Wi-Fi signal characteristic capability information to other devices. For example, a wireless communication device has a Bluetooth signal transmission capability, and its specific capability includes time domain characteristic information, frequency domain characteristic information, and signal strength information of the transmitted Bluetooth signal. The wireless communication device informs other devices of its own non-Wi-Fi signal characteristic capability, so that other devices can decide the access channel mode according to the non-Wi-Fi signal characteristic capability of the current wireless communication device when performing Wi-Fi communication with the current wireless communication device, so as to reduce the interference of non-Wi-Fi signals and improve the stability of communication.

[0087] In some embodiments, the second frame and / or the third frame is one of: a beacon frame, a probe response frame, a multilink probe response frame, an association request frame, a reassociation request frame, an association response frame, a reassociation response frame, an authentication frame, or an action frame.

[0088] It should be noted that the above-mentioned embodiment describes that the second frame and / or the third frame is at least one of a beacon frame, a detection response frame, a multi-link detection response frame, an association request frame, a re-association request frame, an association response frame, a re-association response frame, an authentication frame or an action frame. The specific description thereof can be referred to the specific description in the first frame, and the embodiments of the present application will not be repeated here.

[0089] In some embodiments, the second frame and / or the third frame includes a first field, the non-Wi-Fi signal feature capability information is located in the first field, and the first field is one of the following: a neighbor report NR field, a simplified neighbor report RNR field, or a multiple basic service set identifier MBSSID field.

[0090] It can be understood that the NR field is used to carry information about other access points APs around, and the station STA sends a query frame to the target access point AP to query information about other access points APs around, and the target access point AP sends a response frame containing the NR field to the station STA to feedback information about other access points APs queried periodically to the station STA. For example, the STA sends an Access Network Query Protocol (ANQP) query frame to the AP, and the AP feeds back an ANQP response frame to the STA; or, the AP actively broadcasts information about other APs periodically using the NR field in the beacon frame and the detection response frame; or, in a roaming or multi-AP load balancing scenario, the AP actively recommends information about other APs around to the STA, and after confirming the information, the STA sends a (re)association request to the recommended AP, for example, the AP sends a BSS transition management request (BSS transition management request, BTM request) frame to the STA, and carries information about the recommended AP in the NR field of the BTM request frame, and then the STA sends a BTM response frame, the NR field of which carries information about the AP to be connected to, and sends an authentication frame and a (re)association frame to the target AP to establish a connection with the target AP. The first device or the second device may use the NR field to carry its own non-Wi-Fi signal characteristic capability information.

[0091] In order to reduce the channel resource overhead caused by the field length, the Reduced Neighbour Report (RNR) field is correspondingly cropped and modified based on the NR field, and only includes key information of surrounding APs, such as working channels, SSID, BSSID and other information. The first device or the second device can use the RNR field to carry its own non-Wi-Fi signal feature capability information.

[0092] Basic Service Set Identifier (Multiple BSSID, MBSSID) field. Multiple APs can be created on a radio frequency link of Wi-Fi, and each AP corresponds to a different BSSID. In order to reduce the channel resource overhead of each AP sending management frames such as beacon frames and probe response frames, the 802.11 standard protocol introduces MBSSID technology, that is, beacon frames and probe response frames sent by multiple APs on the same radio frequency are merged into the beacon frame and probe response frame of one AP, that is, the beacon frame and probe response frame of one AP carry information of other APs on the same radio frequency, and this information is placed in the multiple BSSID element field. The field format includes an element identifier element ID, an element length length, a maximum BSSID number indication MaxBSSID Indicator, and optional subelements Optional Subelements, wherein detailed information of other APs is stored in the field Optional Subelements. The first device or the second device can use the MBSSID field to carry non-Wi-Fi signal feature capability information of other APs on the same radio frequency.

[0093] In a specific embodiment, if the second device is an access point device, the beacon frame, the probe response frame or the multi-link probe response frame sent by the second device carries characteristic information of the non-Wi-Fi signal of the neighboring access point AP, and the characteristic information of the non-Wi-Fi signal is carried in the NR field, the RNR field or the MBSSID field.

[0094] In some embodiments, before the first device sends the first frame to the second device, the method further includes:

[0095] The first device receives a fourth frame sent by the second device, where the fourth frame is used to instruct the first device to collect characteristic information of the non-Wi-Fi signal.

[0096] Among them, the fourth frame carries at least one of the following information: receiving end MAC address, collection time information, delay boundary information, collection mode information, received signal strength information, working channel category information, scanning channel number information, type information, and name information.

[0097] It can be understood that the second device sends a fourth frame to the first device, wherein the fourth frame carries at least one of a receiving end MAC address, collection time information, delay boundary information, collection mode information, received signal strength information, working channel category information, scanning channel number information, type information, and name information, and the specific information carried by the fourth frame instructs the first device to collect characteristic information of related non-Wi-Fi signals.

[0098] Specifically, the second device instructs the first device corresponding to the MAC address to collect non-Wi-Fi signal characteristic information; the collection time information is used to indicate the specific time when the first device collects signals; the delay boundary information refers to the maximum allowed collection delay; the collection mode is used to indicate whether the first device performs frequency band scanning based on the local frequency band historical scanning record or in real time; the received signal strength is used to indicate the received signal strength threshold value of the non-Wi-Fi signal collected by the first device; the working channel category information is used to indicate the first device to scan a specific channel or scan the entire frequency band; the type information is used to indicate the first device to scan a specific signal type, such as a Bluetooth signal, an analog signal, or a DSSS signal; the name information is used to indicate the first device to scan a specific signal name.

[0099] In a specific embodiment, see Figure 8 , Figure 8 A schematic diagram of a field format for indicating the collection of characteristic information of non-Wi-Fi signals provided in an embodiment of the present application is shown, such as Figure 8 As shown, the fourth frame sent by the second device to the first device includes fields: MAC address, collection time duration, delay boundary delay boundary, collection mode mode, received signal strength RSSI, working channel category regulatory, scan channel code channel number, type type and name name, which are respectively used to carry the receiving end MAC address, collection time information, delay boundary information, collection mode information, received signal strength information, working channel category information, scan channel number information, type information and name information. The second device sends the following information to the first device in the fourth frame: Figure 8 The field shown carries indication information used to instruct the first device to collect characteristic information of the non-Wi-Fi signal, and sends the fourth frame to the first device, so that the first device collects the characteristic information of the non-Wi-Fi signal according to the indication information carried in the fourth frame.

[0100] It should also be noted that the above embodiment describes the indication information specifically included in the fourth frame, namely, the receiving end MAC address, collection time information, delay boundary information, collection mode information, received signal strength information, working channel category information, scanning channel number information, type information, and name information. In actual application, the second device can use the corresponding field in the transmission frame to carry one or more of the above indication information, or other indication information other than the above examples according to actual needs. The embodiments of the present application are not limited here.

[0101] In some embodiments, the first device obtains characteristic information of the non-Wi-Fi signal, including at least one of the following:

[0102] Obtain characteristic information of non-Wi-Fi signals configured locally;

[0103] Characteristic information of a non-Wi-Fi signal received from a third device is obtained.

[0104] It should be understood that the manner in which the first device acquires the characteristic information of the non-Wi-Fi signal includes: the first device acquires the characteristic information of the non-Wi-Fi signal configured locally, that is, the first device collects the characteristic information of the non-Wi-Fi signal by itself, and sends the characteristic information of the non-Wi-Fi signal collected by itself to the second device, so as to inform the second device that the non-Wi-Fi signal and its characteristic information exist near the first device; correspondingly, the manner in which the first device acquires the characteristic information of the non-Wi-Fi signal may also include: the first device acquires the characteristic information of the non-Wi-Fi signal received from the third device, that is, the third device sends the characteristic information of the non-Wi-Fi signal collected by itself to the first device, and the first device forwards the characteristic information of the non-Wi-Fi signal received from the third device to the second device, so as to realize sharing of the characteristic information of the non-Wi-Fi signal by multiple wireless communication devices, so that the device can perform channel configuration related operations according to the characteristic information of the non-Wi-Fi signal collected by itself and other devices, thereby reducing interference of the non-Wi-Fi signal on the Wi-Fi signal.

[0105] In some embodiments, the third device is an access point AP device or a station STA device.

[0106] It can be understood that the third device can be an access point device, that is, the third device as an access point device sends the characteristic information of the non-Wi-Fi signal to the first device. Correspondingly, according to the device type of the first device (access point device or site device), the third device can use a beacon frame, a probe response frame, a multi-link probe response frame, an association response frame, or a re-association response frame, and carry the characteristic information of the non-Wi-Fi signal through the NR field, the RNR field, or the MBSSID field. In addition to the transmission frames and fields listed above, the third device as an access point device can also send the characteristic information of the non-Wi-Fi signal to the first device in other ways, and the embodiment of the present application is not limited to this.

[0107] The third device may also be a site device, that is, the third device as a site device sends the characteristic information of the non-Wi-Fi signal to the first device. Correspondingly, according to the device type of the first device (access point device or site device), the third device may use a probe request frame, a multi-link probe request frame, an association request frame, a re-association request frame, an authentication frame or an action frame, and select an NR field, an RNR field or an MBSSID field to carry the characteristic information of the non-Wi-Fi signal. In addition to the transmission frames and fields listed above, the third device as a site device may also send the characteristic information of the non-Wi-Fi signal to the first device in other ways, which is not limited in this embodiment of the present application.

[0108] In some embodiments, the characteristic information of the locally configured non-Wi-Fi signal is obtained according to at least one of the following:

[0109] Obtain characteristic information of non-Wi-Fi signals through spectrum scanning;

[0110] Obtain characteristic information of non-Wi-Fi signals according to local non-Wi-Fi services.

[0111] It is understandable that the method of obtaining the characteristic information of the locally configured non-Wi-Fi signal includes: obtaining the characteristic information of the non-Wi-Fi signal through spectrum scanning, that is, the first device determines whether there is a non-Wi-Fi signal by scanning in a certain frequency band, and determines the characteristic information of the non-Wi-Fi signal. Specifically, the first device can use the local scanning radio frequency to perform a full spectrum scan or scan a specific spectrum. Exemplarily, the Wi-Fi signal can operate in the frequency band of 2.4Hz, 5GHz or 6GHz. Therefore, the first device can scan for signals that may interfere with the Wi-Fi signal in the 2.4Hz, 5GHz or 6GHz frequency band. When the non-Wi-Fi signal is detected, the first device locally generates the characteristic information of the non-Wi-Fi signal.

[0112] In a specific embodiment, the first device receives a fourth frame sent by the second device, where the fourth frame is used to instruct the first device to collect characteristic information of the non-Wi-Fi signal. The first device obtains the characteristic information of the corresponding non-Wi-Fi signal through spectrum scanning according to the indication information carried in the fourth frame. For example, the fourth frame carries working channel category information and scanning channel number information, where the working channel category information is 2.4 GHz, and the scanning channel number information is 9 and 10, that is, the second device instructs the first device to scan on channels 9 and 10 in the 2.4 GHz frequency band. The first device scans on channels 9 and 10 in the 2.4 GHz frequency band. When the non-Wi-Fi signal is detected, the first device locally generates the characteristic information of the non-Wi-Fi signal.

[0113] It can be understood that the method of obtaining the characteristic information of the locally configured non-Wi-Fi signal includes: obtaining the characteristic information of the non-Wi-Fi signal according to the local non-Wi-Fi service, the first device itself has a non-Wi-Fi service, that is, the first device also needs to transmit a non-Wi-Fi signal, so the first device can send its own non-Wi-Fi signal characteristic information to the second device, so that when the first device communicates with the first device based on the Wi-Fi technology, it can perform corresponding channel configuration related operations according to the first device's own non-Wi-Fi service, so as to improve the stability of communication with the first device.

[0114] In some embodiments, after acquiring the characteristic information of the non-Wi-Fi signal, the method further includes:

[0115] Perform channel configuration related operations based on the characteristic information of non-Wi-Fi signals.

[0116] The channel configuration related operations include at least one of the following:

[0117] Switch channel operation;

[0118] Select the working channel operation;

[0119] Select direct channel operation;

[0120] Dynamic frequency selection channel operation;

[0121] Preamble code shielding channel configuration operation;

[0122] Energy detection threshold configuration operation.

[0123] It should be understood that the channel switching operation refers to the first device switching from the original working channel to the target working channel with reference to the characteristic information of the non-Wi-Fi signal stored locally or obtained from other devices. For example, the characteristic information of the non-Wi-Fi signal indicates that there is currently a non-Wi-Fi signal using the same working channel as the first device, such as channel 8 in the 2.4GHz band, and the surrounding channels affected by the non-Wi-Fi signal are 7 and 9. Therefore, the first device can choose to switch from channel 8 in the 2.4GHz band to other channels except channels 7 and 9 to avoid the working channel of the non-Wi-Fi signal and the surrounding channels affected by the non-Wi-Fi signal. The channel can be a working channel between a site device and an access point device, a direct connection channel between site devices, etc.

[0124] The operation of selecting a working channel refers to the first device selecting a working channel to be accessed by referring to characteristic information of the non-Wi-Fi signal stored locally or obtained from other devices. For example, the characteristic information of the non-Wi-Fi signal indicates that there is currently a non-Wi-Fi signal using channel 1 in the 2.4 GHz frequency band, but the non-Wi-Fi signal does not affect other surrounding channels. Therefore, the first device can select other channels except channel 1 in the 2.4 GHz frequency band as the working channel.

[0125] The direct channel selection operation means that when the first device is a station device and the first device is about to establish a point-to-point direct link with another station device, the first device can select the direct channel to be accessed by referring to the characteristic information of the non-Wi-Fi signal stored locally or obtained from other devices.

[0126] Dynamic Frequency Selection (DFS) channel operation refers to the first device selecting a radar channel to use or switch to with reference to characteristic information of non-Wi-Fi signals stored locally or obtained from other devices. For example, the first device instructs the second device to scan for radar signals in the 5 GHz frequency band. When the characteristic information of non-Wi-Fi signals fed back by the second device indicates that no radar signals are currently detected in the 5 GHz frequency band, the first device may select a channel in the 5 GHz frequency band that has been scanned and no radar signals are detected as the radar channel to use or switch to.

[0127] The preamble puncturing channel configuration operation refers to when the first device is an access point device, the first device marks a channel that overlaps with or is affected by a non-Wi-Fi signal as a preamble puncturing sub-channel according to characteristic information of the non-Wi-Fi signal to indicate that the sub-channel is unavailable.

[0128] The energy detection threshold value configuration operation means that when the first device accesses a channel with reference to characteristic information of a non-Wi-Fi signal, the characteristic information of the non-Wi-Fi signal indicates that the channel strength of the current non-Wi-Fi signal is higher than the CCA-ED default threshold value, the first device increases the threshold value of CCA-ED within the non-Wi-Fi signal access channel time window, so that the first device can access the channel more easily and improve the channel utilization efficiency.

[0129] In some embodiments, the first device is an access point AP device or a station STA device; the second device is an access point AP device or a station STA device.

[0130] It should be understood that the first device is an access point device or a site device, and the second device is an access point device or a site device, that is, the access point device and the site device can both serve as senders of characteristic information of non-Wi-Fi signals, and send the obtained characteristic information of non-Wi-Fi signals to another access point device or a site device, so that multiple wireless communication devices within the same basic service range can obtain the characteristic information of the current non-Wi-Fi signal, so as to further decide on the access channel mode according to the characteristic information of the non-Wi-Fi signal, thereby reducing signal interference of non-Wi-Fi signals on devices using Wi-Fi communication technology.

[0131] It can be understood that the access point device includes a multi-link access point device, and the site device includes a multi-link site device. When the first device is a multi-link access point device and the second device is a multi-link site device, or the second device is a multi-link access point device and the first device is a multi-link site device, such as Figure 1B As shown, the station device can establish a connection with the same access point device through multiple different links, or, as shown in Figure 1C As shown, the station device can establish connections with multiple access point devices through multiple different links.

[0132] In a specific embodiment, see Figure 4 , Figure 4 A schematic diagram of a flow chart of a method for sending information provided by an embodiment of the present application is shown, such as Figure 4 As shown, the first device obtains characteristic information of the non-Wi-Fi signal, and then sends a first frame carrying the characteristic information of the non-Wi-Fi signal to the second device, and the first device and the second device perform channel configuration related operations according to the characteristic information of the non-Wi-Fi signal.

[0133] In a specific embodiment, see Figure 5 , Figure 5 A schematic diagram of a flow chart of a method for sending information provided by an embodiment of the present application is shown, such as Figure 5 As shown, the first device and the second device exchange their non-Wi-Fi signal characteristic capability information. Specifically, the first device sends the non-Wi-Fi signal characteristic capability information of the first device to the second device, and the second device sends the non-Wi-Fi signal characteristic capability information of the second device to the second device. The first device obtains the characteristic information of the non-Wi-Fi signal, and then the first device sends the first frame carrying the characteristic information of the non-Wi-Fi signal to the second device. The first device and the second device perform channel configuration related operations according to the characteristic information of the non-Wi-Fi signal.

[0134] In a specific embodiment, see Figure 6 , Figure 6A schematic diagram of a flow chart of a method for sending information provided by an embodiment of the present application is shown, such as Figure 6 As shown, the second device instructs the first device to collect characteristic information of the non-Wi-Fi signal. Specifically, the second device sends a fourth frame for instructing the first device to collect characteristic information of the non-Wi-Fi signal, and the first device determines whether to execute the collection instruction. If the first device refuses to execute the collection instruction, the first device sends a response message for indicating the rejection of the instruction to the second device. If the first device receives the collection instruction, the first device obtains the characteristic information of the non-Wi-Fi signal. Then, the first device sends a first frame carrying the characteristic information of the non-Wi-Fi signal to the second device, and the second device performs channel configuration related operations according to the characteristic information of the non-Wi-Fi signal.

[0135] The present application also provides a method for receiving information. Figure 3 , Figure 3 A method for sending information provided by an embodiment of the present application is shown. Figure 3 As shown, the method includes but is not limited to step S210 and step S220.
