[0003] The present application relates to the field of communication technology, and in particular to an information sending method, an information receiving method, a device and a storage medium. Background Art

[0004] Currently, various countries and regions have designated specific electromagnetic wave frequency bands for industrial, scientific, and medical applications, known as the ISM band (Industrial Scientific Medical Band). The ISM band is unlicensed or license-exempt, meaning users do not need to apply for a license from a specialized agency.

[0005] 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, and other products. Therefore, when Wi-Fi technology was first introduced, there was a potential for spectrum conflicts with other wireless products.

[0006] The rapid growth in the number and types of Wi-Fi products is driven by the availability of unlicensed frequency bands, a key factor. However, the widespread adoption of Wi-Fi has led to an increasing number of conflicts between devices using wireless resources in these bands. This has led to signal interference between devices, hindering the application of Wi-Fi technology in various scenarios. Therefore, reducing signal interference when devices communicate using Wi-Fi has become a pressing technical challenge in this field.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present application, the information sending method, information receiving method, device and storage medium provided by the present application are described in detail below with reference to the accompanying drawings.

Rather, these embodiments are provided so that this application will be thorough and complete and will fully convey the scope of this application to those skilled in the art.

[0027] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0028] The terms used herein are used only to describe specific embodiments and are not intended to limit this application. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms, unless the context clearly indicates otherwise. It will also be understood that when the terms "comprising" and / or "made of" are used in this specification, they specify the presence of features, wholes, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or groups thereof.

[0029] In the following description, reference is made to “some embodiments,” which describes a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0030] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and the present application, and will not be interpreted as having an idealized or overly formal meaning, unless clearly defined in the examples of the present application.

[0031] Currently, various countries and regions have designated specific electromagnetic wave frequency bands for industrial, scientific, and medical applications, known as the ISM band (Industrial Scientific Medical Band). The ISM band is unlicensed or license-exempt, meaning users do not need to apply for a license from a specialized agency.

[0032] 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, and other products. Therefore, when Wi-Fi technology was first introduced, there was a potential for spectrum conflicts with other wireless products.

[0033] The rapid growth in the number and types of Wi-Fi products is driven by the availability of unlicensed frequency bands, a key factor. However, the widespread adoption of Wi-Fi has led to an increasing number of conflicts between devices using wireless resources in these bands. This has led to signal interference between devices, hindering the application of Wi-Fi technology in various scenarios. Therefore, reducing signal interference when devices communicate using Wi-Fi has become a pressing technical challenge in this field.

[0034] Based on this, 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 a device uses Wi-Fi communication.

[0035] The information sending method and information receiving method provided in the present application can be applied to a wireless communication system, which 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. The wireless communication system includes an access point (AP) device and a station (STA) device. The station device is also called a non-access point (non-AP) device. The access point device is a repeater in the wireless network and is a device used to connect a wireless terminal device to a local area network (LAN) or the Internet. For example, the access point device may include various forms of macro base stations, micro base stations, relay stations, etc., or the access point device may be a switch or a bridge, etc.; the station device is a client device of the wireless communication system and is a device used to connect to the wireless network and communicate with the access point device or other station devices and access network resources. The station device may be a handheld device, a vehicle-mounted device, a wearable device, or a computing device with wireless communication capabilities. Exemplarily, the site device can be a mobile phone, a tablet computer, or a computer with wireless transceiver capabilities, or it can be a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in a smart city, a wireless terminal in a smart home, and the like.

[0036] Access point devices and station devices can be multi-link devices (MLDs). A multi-link device refers to a wireless communication device that can communicate simultaneously on different channels of the same frequency band, or can communicate simultaneously on different frequency bands. If the access point device is a multi-link device, that is, a multi-link access point device (AP MLD), the device contains one or more access points; if the station device is a multi-link device, that is, a multi-link station device (non-AP MLD), the device contains one or more access points.

[0037] Please refer to Figure 1A, which is a schematic diagram of a network architecture provided in an embodiment of the present application. As shown in Figure 1A, the network architecture of the embodiment of the present application includes access point device 100, access point device 101, site device 200, and site device 201. The site device establishes a communication connection with the access point device through relevant links to access network resources. Specifically, the site device 200 establishes a communication connection with the access point device 100 through link 1, and the site device 201 establishes a communication connection with the access point device 202 through link 2.

[0038] Referring again to Figure 1B, Figure 1B is a schematic diagram of another network architecture provided in an embodiment of the present application. As shown in Figure 1B, the network architecture includes an access point device 100, an access point device 101, a site device 200, and a site device 201. The access point device and the site device are both multi-link devices. The site device establishes a communication connection with the access point device through relevant links to access network resources. Specifically, the site device 200 establishes a communication connection with the access point device 100 through link 1 and link 2, respectively, and the site device 201 establishes a communication connection with the access point device 101 through link 3 and link 4, respectively.

[0039] Referring again to Figure 1C, Figure 1C is a schematic diagram of another network architecture provided in an embodiment of the present application. As shown in Figure 1C, the network architecture includes access point device 100, access point device 101, site device 200, and site device 201. The site device establishes communication connections with multiple access point devices through relevant links to access network resources. Specifically, the site device 200 establishes communication connections with the access point device 100 and the access point 101 through link 1 and link 2, respectively, and the site device 201 establishes communication connections with the access point device 100 and the access point 101 through link 3 and link 4.

[0040] Referring again to Figure 1D, Figure 1D is a schematic diagram of another network architecture provided in an embodiment of the present application. As shown in Figure 1D, the network architecture of the embodiment of the present application includes an access point device 100, a site device 200, a site device 201, and a site device 202. The site device establishes a communication connection with the access point device through relevant links to access network resources. Specifically, the site device 200 establishes a communication connection with the access point device 100 through link 1, the site device 201 establishes a communication connection with the access point device 100 through link 2, and the site device 202 establishes a communication connection with the access point device 100 through link 3. In addition, the site device 200 and the site device 201, the site device 201 and the site device 202, and the site device 200 and the site device 202 establish communication connections through links 4, 5, and 6, respectively, and can directly transmit data to each other.

[0041] The embodiment of the present application first proposes a method for sending information. Please refer to Figure 2. Figure 2 shows an information sending method provided by the embodiment of the present application. As shown in Figure 2, the method includes but is not limited to step S110 and step S120.

[0042] Step S110: The first device obtains characteristic information of the non-Wi-Fi signal.

[0043] It should be understood that non-Wi-Fi signals refer to wireless communication signals other than Wi-Fi signals, and specifically may include wireless communication signals that use the same frequency band as Wi-Fi signals, such as Bluetooth signals, Direct Sequence Spread Spectrum (DSSS) signals, and analog signals. Non-Wi-Fi signal characteristic information refers to the various signal characteristics of non-Wi-Fi signals, and specifically may include characteristic information used to describe the performance, coverage, or connection quality of Wi-Fi signals, such as duration, signal strength, and operating channel.

[0044] In step S120 , the first device sends a first frame to the second device. 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.

[0045] It is understandable that the first device sends characteristic information carrying non-Wi-Fi signals to the second device, enabling the second device to perform channel configuration-related operations based on the characteristic information of the non-Wi-Fi signals. For example, the second device selects an operating channel based on the characteristic information of the non-Wi-Fi signals, thereby avoiding the operating channel of the non-Wi-Fi signals or surrounding channels affected by the non-Wi-Fi signals.

[0046] In an embodiment of the present application, a first device obtains characteristic information of a non-Wi-Fi signal, then sends the characteristic information carrying the non-Wi-Fi signal to a second device. The second device receives the characteristic information carrying the non-Wi-Fi signal sent by the first device, and then performs channel configuration-related operations based on the characteristic information of the non-Wi-Fi signal. This can reduce signal interference when the devices use Wi-Fi communication, reduce data transmission latency of the devices, improve data transmission stability, and increase channel utilization.

[0047] 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 the time domain characteristic information includes at least one of the following: signal period characteristic information or signal duration information.

[0048] 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.

[0049] The non-Wi-Fi signal type information includes at least one of the following: signal type information or signal name information.

[0050] It should be understood that the characteristic information of non-Wi-Fi signals may include time-domain characteristic information. From a time-domain perspective, non-Wi-Fi signals can be divided into periodic and aperiodic signals. Periodic signals refer to signals with fixed access times and periods. For example, Bluetooth signals are periodic signals with access periods of 3.75ms or 7.5ms. Aperiodic signals refer to signals with variable access times or periods. For example, microwave signals generated by microwave ovens are aperiodic signals. When a microwave oven is operating, the microwave signal it generates remains active until it ceases operation. Therefore, the time-domain characteristics of a signal can be described using signal periodicity or duration information. This allows a second device to utilize this signal's time-domain characteristic information to perform channel configuration operations and, from a temporal perspective, to perform channel avoidance and other related operations to reduce signal interference from non-Wi-Fi signals on devices using Wi-Fi communication technology.

[0051] It should be understood that the characteristic information of non-Wi-Fi signals may also include frequency domain characteristic information of the signal. Specifically, the frequency domain characteristic information may include the following: signal transmit power information, received signal strength information, signal operating channel category information, signal operating channel number information, information about the numbers of surrounding channels affected by the signal, or signal bandwidth information.

[0052] It should be noted that signal transmission power information is an indicator used to measure the power used by a wireless communication device when transmitting radio frequency signals, and is typically expressed in decibel milliwatts (dBm). For example, when a first device acts as a transmitter of a non-Wi-Fi signal, it can report the transmission power information of the non-Wi-Fi signal to a second device. Received signal strength information is an indicator used to measure the strength of a received radio frequency signal, and is also typically expressed in decibel milliwatts (dBm). For example, when a first device detects a non-Wi-Fi signal through spectrum scanning, the second device can act as a receiver of the non-Wi-Fi signal and calculate the received signal strength information of the non-Wi-Fi signal and report the received signal strength information to the second device.

[0053] On the one hand, in terms of signal strength, non-Wi-Fi signals are divided into strong and weak signals. Taking the Wi-Fi signal thresholds of (-82dBm, -62dBm) as an example, when the interference signal strength is less than the lowest threshold, i.e., less than -82dBm, the Wi-Fi device is less affected by the signal interference. When the interference signal strength is within the threshold, the Wi-Fi device can still access the channel. However, when the interference signal strength is greater than the highest threshold, i.e., greater than -62dBm, the Wi-Fi device will experience severe signal interference and will be almost unable to access the channel. Therefore, the signal strength characteristics of the signal can be described using the signal's transmit power information or received signal strength information, allowing the second device to perform channel configuration-related operations based on the signal strength characteristics. It can also perform channel avoidance and other related operations based on the signal strength to reduce the signal interference of non-Wi-Fi signals on devices using Wi-Fi communication technology.

[0054] 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. The 2.4 GHz band operates from 2.402 GHz to 2.483 GHz. Each channel has a bandwidth of 22 MHz, with the center frequency of each channel increasing in multiples of 5 MHz. This results in an effective bandwidth of 20 MHz, and the remaining 2 MHz is used as an isolation protection bandwidth. In the entire 2.4 GHz band, only channels 1, 6, and 11 do not overlap. This means that channels other than 1, 6, and 11 in the 2.4 GHz band interfere with adjacent channels. Therefore, a signal can be described by the channel coding information of the surrounding channels it affects. For example, if a non-Wi-Fi signal operates on channel 8 in the 2.4 GHz band, the channel coding information of the surrounding signals affected by the signal is 7 and 9. The signal's bandwidth refers to the spectrum occupied by the signal and is typically expressed in Hertz (Hz). For example, the channel bandwidth of a Bluetooth signal is 1 MHz, while 4G LTE uses 5, 10, or 20 MHz.

[0055] On the other hand, from a frequency domain perspective, non-Wi-Fi signals can be divided into wideband and narrowband signals. Wideband signals refer to signals operating in a wider frequency band. For example, signals generated by Bluetooth devices and microwave ovens operate across the entire 2.4 GHz band. Narrowband signals refer to signals operating in a narrower frequency band. For example, signals generated by analog cordless phones operate only on channels 1, 2, and 3 within the corresponding frequency band, and signals generated by direct sequence spread spectrum (DSSS) phones operate only on channel 165 within the corresponding frequency band. Therefore, the frequency domain characteristics of a signal can be described using information such as the signal's operating channel category, operating channel number, numbers of surrounding channels affected by the signal, or bandwidth information. This allows a second device to utilize this frequency domain characteristic information to perform channel configuration operations and, from a frequency domain perspective, perform operations such as channel avoidance to reduce signal interference from non-Wi-Fi signals on devices using Wi-Fi communication technology.

[0056] 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 refers to the type of the non-Wi-Fi signal, such as a Bluetooth signal, a direct sequence spread spectrum signal, or an analog signal. The signal name information refers to the specific name of the non-Wi-Fi signal.

[0057] In a specific embodiment, please refer to Figure 7, which shows a schematic diagram of the field format of characteristic information of a non-Wi-Fi signal provided by an embodiment of the present application. As shown in Figure 7, the first frame sent by the first device to the second device includes the following fields: period, duration, transmit power TX power (Transmit Power), received signal strength RSSI (Received Signal Strength Indicator), operating channel type Operating channel, affected channel Affected channel The channel, bandwidth, type, and name fields, respectively, carry the signal period characteristic information, signal duration information, transmit power information, signal strength information, operating channel category information, operating channel number information, numbers of surrounding channels affected by the signal, bandwidth information, signal type information, and signal name information of the non-Wi-Fi signal. By including the characteristic information of the non-Wi-Fi signal in the fields shown in FIG7 in the first frame and sending the first frame to the second device, the second device can analyze the non-Wi-Fi signal based on the characteristic information in the time domain, frequency domain, and signal strength dimensions, and further determine the channel access method. This reduces interference of non-Wi-Fi signals on Wi-Fi signal transmission by the device, reduces data transmission latency, and improves data transmission stability and channel utilization.

[0058] It should also be noted that the above embodiment describes specific information included in the characteristic information of non-Wi-Fi signals, namely, signal period characteristic information, signal duration information, signal transmit power information, received signal strength information, signal operating channel category information, signal operating channel number information, signal affected surrounding channel number information, signal bandwidth information, signal type information, or signal name information. In actual applications, the first device may use corresponding fields 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 negotiated provisions. This embodiment of the present application is not limited hereto.

[0059] In some embodiments, the first frame is one of the following: 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.

[0060] 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.

[0061] The following describes the types of management frames. An AP can be an access point (AP), a multilink access point (AP MLD), or an affiliated AP of an AP MLD. A STA can be a station (STA), a multilink station (non-AP MLD), or an affiliated station of a non-AP MLD.

[0062] 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 basic information of the BSS, such as the basic service set identifier (BSSID), service set identifier (SSID), channel, frequency, signal strength, country code, etc.

[0063] Probe Request frame: A probe request frame is sent by a STA to an AP to detect surrounding BSSs. If the request frame specifies an SSID, the AP in the BSS with the same SSID as the requested SSID responds with a probe response frame. If the request frame does not specify an SSID, all APs in the BSS respond.

[0064] Probe Response frame: The AP responds to the probe request frame sent by the STA with a probe response frame.

[0065] Multi-link Probe Request frame: A probe request frame is sent by a STA to an AP to detect the MLD of surrounding APs.

[0066] Multi-link Probe Response frame: The AP MLD responds to the multi-link probe request frame sent by the STA with a multi-link probe response frame.

[0067] Association Request frame: After a STA finds an AP and passes authentication, it sends an Association Request frame to the AP to request the AP to associate. The Association Request frame carries basic information about the STA.

[0068] Association Response frame: The AP responds to the association request frame sent by the STA with an association response frame.

[0069] Reassociation Request frame: When a STA moves away from the original AP and finds another new AP with a stronger signal in the same ESS, the STA sends a reassociation request frame to the new AP.

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

[0071] Disassociation Frame: The disassociation frame is sent by the STA to the AP to terminate the association with the AP.

[0072] Authentication Frame: STA sends an authentication frame to AP. AP performs authentication based on the password entered and sends the authentication result to STA.

[0073] Deauthentication Frame: The deauthentication frame is used to terminate the authentication relationship. Specifically, the STA sends a deauthentication frame to the AP to proactively forget the SSID, or the AP sends a deauthentication frame to the STA to proactively propose to terminate the connection with the STA.

[0074] Action Frame: A STA sends an action frame to the AP to request the AP to perform a specific operation.

[0075] Therefore, when the first device is an AP, it can use the idle field in a beacon frame, probe response frame, multilink probe response frame, association response frame, reassociation response frame, or deauthentication frame to carry characteristic information of non-Wi-Fi signals. When the first device is a STA, it can use the idle field in an authentication frame, probe request frame, multilink probe request frame, reassociation request frame, disassociation frame, deauthentication frame, or action frame to carry characteristic information of non-Wi-Fi signals.

[0076] 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 multilink probe request frame, a multilink probe response frame, an association request frame, an association response frame, a reassociation request frame, a reassociation response frame, a disassociation frame, an authentication frame, a deauthentication frame, or an action frame. In actual applications, the first device may 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. This embodiment of the present application is not limited here.

[0077] In some embodiments, the information sending method further includes at least one of the following steps:

[0078] The first device sends a second frame to the second device, where the second frame carries the non-Wi-Fi signal feature capability information of the first device.

[0079] 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.

[0080] It is understandable 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. 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. In other words, 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, if a wireless communication device has Bluetooth signal transmission capability, its specific capability includes time domain characteristic information, frequency domain characteristic information, and signal strength information of the transmitted Bluetooth signal. By informing other devices of its own non-Wi-Fi signal characteristic capability, the other device can determine the channel access method based on the non-Wi-Fi signal characteristic capability of the current wireless communication device when conducting Wi-Fi communication with the current wireless communication device, thereby reducing interference from non-Wi-Fi signals and improving communication stability.

[0081] In some embodiments, the second frame and / or the third frame is one of the following: 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.

[0082] It should be noted that the above embodiment describes that the second frame and / or the third frame is at least one of a beacon frame, a probe response frame, a multi-link 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. The specific description can be found in the specific description in the first frame, and the embodiments of the present application will not be repeated here.

[0083] In some embodiments, the second frame and / or the third frame includes a first field, and the non-Wi-Fi signal feature capability information is located in the first field, where the first field is one of the following: a neighbor report NR field, a reduced neighbor report RNR field, or a multiple basic service set identifier MBSSID field.

[0084] It is understood that the NR field is used to carry information about other nearby access points (APs). A station STA sends a query frame to a target AP to query information about other nearby APs. The target AP then sends a response frame containing the NR field to the station STA to provide feedback about the queried information about other APs. For example, a STA sends an Access Network Query Protocol (ANQP) query frame to an AP, and the AP returns an ANQP response frame to the STA. Alternatively, an AP proactively broadcasts information about other APs using the NR field in beacon frames or probe response frames. Alternatively, in roaming or multi-AP load balancing scenarios, an AP proactively recommends information about other nearby APs to a STA. After confirming this information, the STA sends a (re)association request to the recommended AP. For example, the AP sends a BSS transition management request (BTM request) frame to the STA, with the recommended AP information carried in the NR field of the BTM request frame. The STA then sends a BTM response frame containing information about the desired AP, and sends an authentication frame and a (re)association frame to the target AP to establish a connection. The first device or the second device can use the NR field to carry its own non-Wi-Fi signal characteristic capability information.

[0085] To reduce the channel resource overhead caused by field length, the Reduced Neighbor Report (RNR) field has been shortened and modified based on the NR field to include only key information about surrounding APs, such as the operating channel, SSID, and BSSID. The first or second device can use the RNR field to carry its own non-Wi-Fi signal feature capability information.

[0086] The Basic Service Set Identifier (MBSSID) field specifies that multiple access points (APs) can be created on a single Wi-Fi radio link, each corresponding to a different BSSID. To reduce the channel resource overhead of each AP sending management frames such as beacon frames and probe response frames, the 802.11 standard introduces MBSSID technology. This technology combines beacon frames and probe response frames sent by multiple APs on the same radio into a single AP's beacon and probe response frames. This means that a single AP's beacon and probe response frames carry information about other APs on the same radio. This information is stored in the Multiple BSSID Element field. This field format includes an element identifier (element ID), an element length (length), a MaxBSSID Indicator (MaxBSSID Indicator), and optional subelements. Detailed information about other APs is stored in the Optional Subelements field. The first or second device can use the MBSSID field to carry non-Wi-Fi signal feature capability information about other APs on the same radio.

[0087] In a specific embodiment, if the second device is an access point device, the beacon frame, probe response frame, or multilink 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.

[0088] In some embodiments, before the first device sends the first frame to the second device, the method further includes:

[0089] 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 non-Wi-Fi signals.

[0090] 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.

[0091] It can be understood that the second device sends a fourth frame to the first device, where the fourth frame carries at least one of the following: a 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 specific information carried in the fourth frame instructs the first device to collect characteristic information of relevant non-Wi-Fi signals.

[0092] 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 allowable collection delay; the collection mode is used to indicate whether the first device performs frequency band scanning based on local frequency band historical scan records or in real time; the received signal strength is used to indicate the received signal strength threshold of the non-Wi-Fi signals collected by the first device; the operating channel category information is used to indicate whether the first device scans a specific channel or scans the entire frequency band; the type information is used to indicate whether the first device scans for a specific signal type, such as Bluetooth signals, analog signals, or DSSS signals; and the name information is used to indicate whether the first device scans for a specific signal name.

[0093] In a specific embodiment, refer to FIG8 , which illustrates a schematic diagram of a field format for instructing the collection of characteristic information of non-Wi-Fi signals, provided by an embodiment of the present application. As shown in FIG8 , a fourth frame sent by the second device to the first device includes the following fields: MAC address, collection duration, delay boundary, collection mode, RSSI, regulatory operating channel category, scanning channel number, type, and name. These fields respectively carry the receiving end MAC address, collection time information, delay boundary information, collection mode information, received signal strength information, operating channel category information, scanning channel number information, type information, and name information. The second device carries instruction information for instructing the first device to collect characteristic information of non-Wi-Fi signals in the fields shown in FIG8 , and sends the fourth frame to the first device, causing the first device to collect characteristic information of non-Wi-Fi signals based on the instruction information carried in the fourth frame.

[0094] 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.

[0095] In some embodiments, the first device obtains characteristic information of the non-Wi-Fi signal, including at least one of the following:

[0096] Obtain characteristic information of locally configured non-Wi-Fi signals;

[0097] Characteristic information of a non-Wi-Fi signal received from a third device is obtained.

[0098] It should be understood that the first device may obtain characteristic information of non-Wi-Fi signals by obtaining locally configured characteristic information of non-Wi-Fi signals. Specifically, the first device collects characteristic information of non-Wi-Fi signals and transmits the collected characteristic information to a second device to notify the second device of the presence of non-Wi-Fi signals and their characteristic information near the first device. Alternatively, the first device may obtain characteristic information of non-Wi-Fi signals received from a third device. Specifically, the third device transmits the collected characteristic information of non-Wi-Fi signals to the first device, and the first device forwards the received characteristic information of non-Wi-Fi signals from the third device to the second device. This enables multiple wireless communication devices to share the characteristic information of non-Wi-Fi signals, enabling the devices to perform channel configuration-related operations based on the characteristic information of non-Wi-Fi signals collected by themselves and other devices, thereby reducing interference of non-Wi-Fi signals on Wi-Fi signals.

[0099] In some embodiments, the third device is an access point AP device or a station STA device.

[0100] It is understandable that the third device may 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, depending on the device type of the first device (access point device or station device), the third device may use a beacon frame, a probe response frame, a multilink probe response frame, an association response frame, or a reassociation 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 may also send the characteristic information of the non-Wi-Fi signal to the first device through other methods, which is not limited in this embodiment of the present application.

[0101] The third device may also be a station device. That is, the third device, acting as a station device, transmits characteristic information of non-Wi-Fi signals to the first device. Accordingly, depending on the device type of the first device (access point device or station device), the third device may use a probe request frame, a multilink probe request frame, an association request frame, a reassociation request frame, an authentication frame, or an action frame, and may select the NR field, the RNR field, or the MBSSID field to carry the characteristic information of non-Wi-Fi signals. In addition to the transmission frames and fields listed above, the third device, acting as a station device, may also transmit characteristic information of non-Wi-Fi signals to the first device through other means, which are not limited in this embodiment of the present application.

[0102] In some embodiments, the characteristic information of the locally configured non-Wi-Fi signal is obtained according to at least one of the following:

[0103] Obtain characteristic information of non-Wi-Fi signals through spectrum scanning;

[0104] Obtain characteristic information of non-Wi-Fi signals based on local non-Wi-Fi services.

[0105] 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 in a certain frequency band by scanning, and determines the characteristic information of the non-Wi-Fi signal. Specifically, the first device can use the local scanning radio frequency to perform full spectrum scanning or scan a specific spectrum. Exemplarily, the Wi-Fi signal can operate in the frequency band of 2.4 Hz, 5 GHz or 6 GHz. Therefore, the first device can scan for signals that may interfere with the Wi-Fi signal in the 2.4 Hz, 5 GHz or 6 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.

[0106] In a specific embodiment, a first device receives a fourth frame sent by a second device. The fourth frame is used to instruct the first device to collect characteristic information of non-Wi-Fi signals. The first device obtains the corresponding characteristic information of the non-Wi-Fi signals through spectrum scanning based on the instruction information carried in the fourth frame. For example, the fourth frame carries operating channel category information and scanning channel number information, where the operating channel category information is 2.4 GHz and the scanning channel numbers are 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 a non-Wi-Fi signal is detected, the first device locally generates characteristic information of the non-Wi-Fi signal.

[0107] It is understood that the method for obtaining characteristic information of the locally configured non-Wi-Fi signal includes: obtaining characteristic information of the non-Wi-Fi signal based on local non-Wi-Fi services. The first device itself has non-Wi-Fi services, that is, the first device also needs to transmit non-Wi-Fi signals. Therefore, the first device can send the characteristic information of its own non-Wi-Fi signal to the second device. When the first device communicates with the first device based on Wi-Fi technology, it can perform corresponding channel configuration-related operations based on the first device's own non-Wi-Fi services, thereby improving the stability of communication with the first device.

[0108] In some embodiments, after acquiring characteristic information of the non-Wi-Fi signal, the method further includes:

[0109] Perform channel configuration operations based on the characteristics of non-Wi-Fi signals.

[0110] The channel configuration-related operations include at least one of the following:

[0111] Switch channel operation;

[0112] Select working channel operation;

[0113] Select direct channel operation;

[0114] Dynamic frequency selection channel operation;

[0115] Preamble shielding channel configuration operation;

[0116] Energy detection threshold configuration operation.

[0117] It should be understood that the channel switching operation refers to the first device switching from the original operating channel to the target operating channel based on the characteristic information of the non-Wi-Fi signal stored locally or obtained from another device. For example, the characteristic information of the non-Wi-Fi signal indicates that a non-Wi-Fi signal currently uses the same operating channel as the first device, such as channel 8 in the 2.4 GHz 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 2.4 GHz band to a channel other than channels 7 and 9 to avoid the operating channel of the non-Wi-Fi signal and the surrounding channels affected by the non-Wi-Fi signal. The channel can be the operating channel between the station device and the access point device, the direct connection channel between station devices, etc.

[0118] Selecting an operating channel involves the first device selecting a channel to be connected based on locally stored or acquired non-Wi-Fi signal characteristic information from another device. For example, the characteristic information of the non-Wi-Fi signal indicates that a non-Wi-Fi signal currently uses channel 1 in the 2.4 GHz band, but the non-Wi-Fi signal does not affect other surrounding channels. Therefore, the first device may select a channel other than channel 1 in the 2.4 GHz band as the operating channel.

[0119] 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 refer to the characteristic information of the non-Wi-Fi signal stored locally or obtained from other devices to select the direct channel to be connected.

[0120] Dynamic Frequency Selection (DFS) channel operation refers to a first device selecting a radar channel to use or switch to based on non-Wi-Fi signal characteristic information stored locally or obtained from other devices. For example, if the first device instructs a second device to scan for radar signals in the 5 GHz band, and the non-Wi-Fi signal characteristic information fed back by the second device indicates that no radar signals are currently detected in the 5 GHz band, the first device can select a previously scanned channel in the 5 GHz band where no radar signals were detected as the radar channel to use or switch to.

[0121] The preamble puncturing channel configuration operation refers to, when the first device is an access point device, marking a channel that overlaps with or is affected by a non-Wi-Fi signal as a preamble puncturing sub-channel based on characteristic information of the non-Wi-Fi signal, to indicate that the sub-channel is unavailable.

[0122] Energy detection threshold configuration involves increasing the CCA-ED threshold during the non-Wi-Fi signal access time window. This increases the channel strength when a first device accesses a channel based on non-Wi-Fi signal characteristic information. If the non-Wi-Fi signal characteristic information indicates that the current non-Wi-Fi signal channel strength is greater than the default CCA-ED threshold, the first device increases the CCA-ED threshold during the non-Wi-Fi signal access time window. This makes it easier for the first device to access the channel and improves channel utilization.

[0123] 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.

[0124] It should be understood that the first device is an access point device or a station device, and the second device is an access point device or a station device. In other words, the access point device and the station device can both serve as senders of characteristic information of non-Wi-Fi signals, and transmit the obtained characteristic information of non-Wi-Fi signals to another access point device or a station device. This enables multiple wireless communication devices within the same basic service range to obtain the characteristic information of the current non-Wi-Fi signals, and thus to further determine the channel access method based on the characteristic information of the non-Wi-Fi signals, thereby reducing signal interference of non-Wi-Fi signals on devices using Wi-Fi communication technology.

[0125] 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, as shown in Figure 1B, the site device can establish a connection with the same access point device through multiple different links, or, as shown in Figure 1C, the site device can establish a connection with multiple access point devices through multiple different links.

[0126] In a specific embodiment, referring to FIG. 4 , FIG. 4 illustrates a flow diagram of an information transmission method provided in an embodiment of the present application. As shown in FIG. 4 , a first device obtains characteristic information of a non-Wi-Fi signal. The first device then transmits a first frame carrying the characteristic information of the non-Wi-Fi signal to a second device. The first and second devices then perform channel configuration-related operations based on the characteristic information of the non-Wi-Fi signal.

[0127] In a specific embodiment, referring to FIG. 5 , FIG. 5 illustrates a flowchart of an information transmission method provided by an embodiment of the present application. As shown in FIG. 5 , a first device and a second device exchange their respective non-Wi-Fi signal characteristic capability information. Specifically, the first device transmits a message carrying the first device's non-Wi-Fi signal characteristic capability information to the second device, and the second device transmits a message carrying the second device's non-Wi-Fi signal characteristic capability information to the second device. The first device obtains the non-Wi-Fi signal characteristic information, and then transmits a first frame carrying the non-Wi-Fi signal characteristic information to the second device. The first and second devices then perform channel configuration-related operations based on the non-Wi-Fi signal characteristic information.

[0128] In a specific embodiment, referring to FIG. 6 , FIG. 6 illustrates a flowchart of an information transmission method provided by an embodiment of the present application. As shown in FIG. 6 , a second device instructs a first device to collect characteristic information of non-Wi-Fi signals. Specifically, the second device transmits a fourth frame to the first device, instructing the collection of characteristic information of non-Wi-Fi signals. The first device decides whether to execute the collection instruction. If the first device rejects the collection instruction, the first device transmits a response message to the second device indicating the rejection of the instruction. If the first device receives the collection instruction, the first device obtains the characteristic information of the non-Wi-Fi signals. The first device then transmits a first frame carrying the characteristic information of the non-Wi-Fi signals to the second device. The second device performs channel configuration-related operations based on the characteristic information of the non-Wi-Fi signals.

[0129] An embodiment of the present application also provides an information receiving method. Please refer to Figure 3. Figure 3 shows an information sending method provided by an embodiment of the present application. As shown in Figure 3, the method includes but is not limited to step S210 and step S220.

[0130] In step S210 , the second device receives a first frame sent by the first device, where the first frame carries characteristic information of a non-Wi-Fi signal.

[0131] Step S220: Perform channel configuration-related operations based on the characteristic information of the non-Wi-Fi signal.

[0132] In this embodiment of the present application, a second device receives a first frame sent by a first device that carries characteristic information of a non-Wi-Fi signal. The second device then performs channel configuration-related operations based on the characteristic information of the non-Wi-Fi signal. This allows the second device to avoid operating channels of non-Wi-Fi signals or channels affected by non-Wi-Fi signals. This reduces signal interference between devices using Wi-Fi communication technology, reduces data transmission latency between devices, improves data transmission stability, and improves channel utilization.

[0133] 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,

[0143] It should be noted that the above embodiment proposes that the first device and the second device can exchange their own non-Wi-Fi signal characteristic capability information.

[0146] In some embodiments, the second frame and / or the third frame includes a first field, and the non-Wi-Fi signal characteristic capability information is located in the first field, where the first field is one of the following: a neighbor report (NR) field, a reduced neighbor report (RNR) field, or a multiple basic service set identifier (MBSSID) field.

[0147] It should be noted that the above embodiment proposes that the second frame and / or the third frame includes a first field, and the first field is an NR field, an RNR field or an MBSSID field. For detailed description, please refer to the description of the information sending method provided in the embodiment of the present application, and will not be repeated here.

[0148] In some embodiments, before the second device receives the first frame sent by the first device, the method further includes: the second device sending a fourth frame to the first device, wherein the fourth frame is used to instruct the first device to collect characteristic information of the non-Wi-Fi signal.

[0149] 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, scan channel number information, type information, and name information.

[0153] It is understandable that after receiving the first frame carrying characteristic information of the non-Wi-Fi signal sent by the first device, the second device may choose to forward the received characteristic information of the non-Wi-Fi signal to the fourth device, so that the fourth device can obtain the characteristic information of the non-Wi-Fi signal collected by the first device, thereby enabling multiple wireless communication devices to share the characteristic information of the non-Wi-Fi signal. This allows the devices to perform channel configuration-related operations based on the characteristic information of the non-Wi-Fi signal collected by themselves and other devices, thereby reducing interference of non-Wi-Fi signals on Wi-Fi signals.
