Description

Communication method, device and computer-readable storage medium

[0001] This application claims priority to the Chinese patent application with application number 202311051086.6 filed with the State Intellectual Property Office of China on August 18, 2023, and priority to the Chinese patent application with the invention name “A communication method, device and computer-readable storage medium”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of wireless communication technologies, and in particular to a communication method, device, and computer-readable storage medium. Background Art

[0003] In wireless local area network (WLAN) sensing switching technology, a station (STA) can obtain information about surrounding access points (APs) by passively scanning and listening to beacon frames or actively scanning and sending probe request frames.

[0004] As the perceived / measured target moves, the original sensing node's perception and measurement accuracy of the perceived target will decrease, or even lead to perception and measurement interruption. At this time, passively listening to beacon frames sent by surrounding APs or actively receiving probe response frames replied by surrounding APs, and performing perception switching based solely on the surrounding AP perception capabilities and signal strength, may cause the perceived / measured target to be outside the perception and measurement range of the existing perception and measurement node. When the perceived / measured target exceeds the AP perception and measurement range, perception and measurement of the perceived target can no longer be performed. In this scenario, the STA re-probes and scans the surrounding nodes, reducing the efficiency of the perception switching process.

[0074] The following is a description of the technical terms that may appear in the embodiments of this application. The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0075] (1) Perception

[0076] Sensing initiator: A station that initiates a sensing process.

[0077] Sensing responder: A station that participates in a sensing process initiated by a sensing initiator.

[0078] SBP initiator: A station that initiates a SBP process.

[0079] SBP responder: A station that participates in a proxy perception process initiated by a proxy perception initiator, acting as the perception initiator in the perception process.

[0080] (2) Sensing by proxy (SBP)

[0081] Proxy-based sensing means that a non-AP STA can request an AP to perform WLAN sensing and have the AP provide feedback on the sensing results. The non-AP STA that initiates the SBP process is called the SBP initiator, and the AP that participates in SBP as a proxy is called the SBP responder. The AP is also the sensing initiator of the SBP sensing process.

[0082] In the IEEE 802.11bf protocol, the process of performing SBP in the sub-7 GHz band can include four stages:

[0083] During the SBP setup phase, the SBP initiator sends an SBP request frame to the SBP responder, which contains configuration parameters for the SBP process. Upon receiving the SBP request frame, the SBP responder sends an SBP response frame to the SBP initiator. If the configuration parameters match the SBP responder's settings, the SBP response frame accepts the SBP request and successfully establishes the SBP. Otherwise, the SBP response frame rejects the SBP request and fails the SBP setup.

[0084] Perception measurement phase: When the SBP is successfully established, the SBP responder, as the perception initiator, initiates a perception process to one or more perception responders. The perception process includes the perception measurement setup phase and the perception measurement instance phase. The perception measurement setup phase includes the perception initiator sending a DMG measurement setup request frame to the perception responder, and the perception responder sending a DMG measurement setup response frame to the perception initiator. The perception measurement performed in the sub-7GHz frequency band can be a trigger-based (TB) type perception measurement.

[0085] SBP reporting phase: After obtaining the perception measurement results, the SBP responder feeds the results back to the SBP initiator via an SBP report frame.

[0086] SBP termination phase: SBP can be terminated by either the SBP initiator or the SBP responder by sending an SBP termination frame.

[0087] It should be understood that the embodiments of the present application can be applied to sensing systems, and can also be applied to systems that comply with IEEE 802.11 system standards, such as 802.11bf, 802.11ax, 802.11be, or next-generation standards, such as wireless local area network systems of 802.11 series protocols such as Wi-Fi 8, UHR, Wi-Fi AI, or wireless personal area network systems based on ultra-wideband UWB, etc., and can also be applied to wireless local area network (WLAN) scenarios. Alternatively, the embodiments of the present application can also be applied to wireless local area network systems such as the Internet of Things (IoT) network or the Vehicle to X (V2X) network. Of course, the embodiments of the present application can also be applied to other possible communication systems, such as 5G communication systems and subsequently evolved cellular communication systems.

[0088] The following uses the scenario in which the embodiments of the present application can be applied to WLAN as an example. It should be understood that WLAN started with the 802.11a / g standard and has gone through 802.11n, 802.11ac, 802.11ax, and the currently under discussion 802.11be and Wi-Fi 8. Among them, 802.11n can also be called high throughput (HT); 802.11ac can also be called very high throughput (VHT); 802.11ax can also be called high efficiency (HE) or Wi-Fi 6; 802.11be can also be called extremely high throughput (EHT) or Wi-Fi 7, and standards before HT, such as 802.11a / b / g, are collectively referred to as non-HT.

[0089] Please refer to Figure 1, which is a schematic diagram of a network architecture provided by an embodiment of the present application. As shown in Figure 1, a network architecture including one wireless access point AP and two stations is used as an example for explanation. The STA associated with the AP can receive wireless frames sent by the AP and can also send wireless frames to the AP. In addition, the embodiment of the present application is also applicable to communication between APs. For example, each AP can communicate with each other through a distributed system (DS), and the embodiment of the present application is also applicable to communication between STAs. It should be understood that the number of APs and STAs in Figure 1 is only an example, and can be more or less.

[0090] The STA involved in the embodiments of the present application is a device with wireless communication capabilities that supports communication using the WLAN protocol and has the ability to communicate with other stations or access points in the WLAN network. In a WLAN system, a station can be referred to as a non-access point station (non-AP STA). For example, an STA is any user communication device that allows a user to communicate with an AP and, therefore, with a WLAN. The device can be a complete device or a chip or processing system installed in the complete device. Devices equipped with these chips or processing systems can implement the methods and functions of the embodiments of the present application under the control of the chip or processing system. For example, a STA may be any user terminal, user device, access device, subscriber station, subscriber unit, mobile station, user agent, user equipment, or other names with wireless communication capabilities. User terminals may include any handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem with wireless communication capabilities, as well as various forms of user equipment (UE), mobile station (MS), terminal, terminal equipment, portable communication devices, handsets, portable computing devices, entertainment devices, gaming devices or systems, global positioning system devices, or any other suitable devices configured to conduct network communication via a wireless medium. For example, a STA may be a router, switch, or bridge. For ease of description, the above-mentioned devices are collectively referred to as stations or STAs.

[0091] The access point (e.g., AP) involved in the embodiments of the present application is a device with wireless communication capabilities, supports communication using the WLAN protocol, and has the function of communicating with other devices in the WLAN network (e.g., stations or other access points). Of course, it can also have the function of communicating with other devices. In a WLAN system, an access point can be called an access point station (AP STA). The device can be a complete device, or it can be a chip or processing system installed in the complete device. The device installed with these chips or processing systems can implement the methods and functions of the embodiments of the present application under the control of the chip or processing system. The AP in the embodiments of the present application can be a device that provides services for STAs and can support the 802.11 series protocols. For example, the AP can be a communication entity such as a communication server, router, switch, bridge, etc.; the AP can include various forms of macro base stations, micro base stations, relay stations, etc. Of course, the AP can also be a chip and processing system in these various forms of devices, thereby implementing the methods and functions of the embodiments of the present application.

[0092] The AP and STA involved in the embodiments of the present application may be APs and STAs applicable to the IEEE 802.11 system standard. An AP is a device deployed in a wireless communication network to provide wireless communication functions for its associated STAs. The AP can be used as the hub of the communication system and is typically a network-side product that supports the MAC and PHY of the 802.11 system standard. For example, it may be a base station, router, gateway, repeater, communication server, switch or bridge and other communication equipment, wherein the base station may include various forms of macro base stations, micro base stations, relay stations, etc. Here, for the sake of convenience of description, the above-mentioned devices are collectively referred to as APs. A STA is typically a terminal product that supports the medium access control (MAC) and physical layer (PHY) of the 802.11 system standard, such as a mobile phone, a laptop computer, etc.

[0093] WLAN systems can provide high-speed, low-latency transmission. As WLAN application scenarios continue to evolve, they will be applied to a wider range of scenarios and industries, including the Internet of Things (IoT), the Internet of Vehicles (IoV), the banking industry, corporate offices, stadiums and exhibition halls, concert halls, hotel rooms, dormitories, hospital wards, classrooms, supermarkets, plazas, streets, production workshops, and warehouses. Devices supporting WLAN communication (e.g., access points or stations) can include sensor nodes in smart cities (e.g., smart water meters, smart electricity meters, and smart air quality monitoring nodes), smart devices in smart homes (e.g., smart cameras, projectors, displays, TVs, speakers, refrigerators, washing machines, etc.), nodes in the Internet of Things (IoT), entertainment terminals (e.g., wearable devices such as AR and VR), smart devices in smart offices (e.g., printers, projectors, speakers, and audio systems), IoV devices, infrastructure in daily life (e.g., vending machines, self-service kiosks in supermarkets, self-service checkout machines, and self-service ordering kiosks), and equipment in large sports and music venues. There is no special limitation on the specific forms of STA and AP in the embodiments of the present application, which are only illustrative here.

[0094] In WLAN sensing scenarios, the movement of the perceived or measured target can cause the original sensing node to lose measurement accuracy, degrade perception quality, or even interrupt measurement. Alternatively, the movement of a STA can also cause the original sensing node to lose measurement accuracy, degrade perception quality, or even interrupt measurement.

[0095] To address the issue of deteriorating communication quality, there are currently multiple technical solutions for implementing sensory switching. The following three are illustrative examples:

[0096] Solution 1: Re-detect and scan surrounding nodes.

[0097] Please refer to Figure 2, which is a schematic diagram of a re-scanning surrounding node perception process provided by an embodiment of the present application. As shown in Figure 2, the STA and the surrounding APs re-probe and scan the surrounding APs through probe request / probe response, and re-perform perception measurements on the perception target with the new AP.

[0098] Disadvantages of Solution 1: When a STA or a sensed / measured target moves, it autonomously switches to an AP with a stronger surrounding signal. This AP switching method has a high latency.

[0099] Solution 2: Fast transition (FT) mechanism.

[0100] A STA may switch from a current AP to a target AP through a FT mechanism, where the FT mechanism may include an over-the-air FT mechanism and an over-the-DS FT mechanism.

[0101] Disadvantages of Solution 2: Compared to Solution 1, Solution 2 can save authentication and handshake processes during the communication handover process, improving communication handover efficiency. Although Solution 2 solves the problem of high latency when a mobile STA switches to an AP, if both the STA and the AP change and the communication quality between the STA and the AP remains stable, the existing FT mechanism will reduce the original sensing node's measurement accuracy of the sensing target as the sensing / measured target moves, or even cause the sensing measurement to be interrupted.

[0102] Solution 3: Sensing by proxy (SBP).

[0103] Please refer to Figure 3, which is a schematic diagram of an SBP process provided by an embodiment of the present application. When the STA and AP's perception measurement accuracy for a sensing target decreases, the STA can request the AP to perform perception measurements with other STAs within the sensing range. As shown in Figure 3, STA1 and the AP exchange SBP request / response frames, requesting the AP to perform SBP. STA1 acts as the SBP initiator, and the AP acts as the SBP responder. After responding to the SBP request frame sent by STA1, the AP searches for STA2 within the BBS and completes the sensing operation with STA2.

[0104] Disadvantages of Solution 3: When the perceived / measured target exceeds the AP's sensing and measurement range, the SBP solution cannot continue to sense and measure the perceived target. Secondly, during the sensing process between the AP and STA1, if the perception measurement accuracy decreases and the AP does not support SBP, the STA can only rescan other surrounding sensing nodes. This will cause problems such as prolonged perception switching time and loss of perception measurement targets.

[0105] Therefore, the technical problem to be solved by this application may be how to improve the efficiency of the perception switching process.

[0106] Based on the above, the present application proposes a communication method, which will be described below through the following embodiments. Some of these communication methods are only applicable to part of the process in the perception handover, while some can be applied to any one or more processes in the perception handover. It should be understood that these communication methods can be used in combination with each other. For example, one process in the perception handover may use one method and another process may use another method, or a process in the perception handover may use both one method and another method.

[0107] It should be understood that the perception switching may change as the technical solution evolves, and the technical solution provided in this application is not limited to the process described below. Furthermore, the description of the scenario in the embodiments of this application is only an example, and does not limit the solution of the embodiments of this application to be applied only to the described scenario. It is also applicable to scenarios with similar problems.

[0108] A communication method provided by an embodiment of the present application is described below. Please refer to Figure 4, which is a process interaction diagram of a communication method provided by an embodiment of the present application. Figure 4 takes the first device and the second device as an example of the execution subject of the interaction diagram to illustrate the method, but the present application does not limit the execution subject of the interaction diagram. For example, the first device in Figure 4 can also be a chip, chip system, or processor that supports the first device to implement the method, or a logic module or software that can implement all or part of the functions of the first device; the second device in Figure 4 can also be a chip, chip system, or processor that supports the second device to implement the method, or a logic module or software that can implement all or part of the functions of the second device. Among them, the first device and the third device can be APs, and the second device can be STA. As shown in Figure 4, the communication method includes but is not limited to the following steps:

[0109] S401: A first device obtains first information, where the first information includes perception information of at least one third device that can perceive and switch with a second device.

[0110] During the wireless sensing process, if the sensing accuracy is detected to have decreased, the first device may obtain first information, for example, from a third device. The first information includes sensing information of at least one third device that can perform sensing handover with the second device. The sensing information of the third device includes at least one of the third device's BSSID, location information, and whether it has sensing capabilities. In one possible implementation, the sensing information of the third device may also include location information and whether multi-link operation is enabled.

[0111] The first device obtains the first information, and the specific implementation method may be as follows:

[0112] In a first possible implementation, the first device may obtain the first information from the third device wirelessly. For example, refer to Figure 5, which is a signaling flow chart between devices provided in an embodiment of the present application. As shown in Figure 5, the first device may send a first frame to the third device, where the first frame is used to request the second device to switch perception. After receiving the first frame, the third device may send a second frame in response to the first frame to the first device, where the second frame may include perception information of the third device.

[0113] For example, the first frame may be a sensing switch request frame, and the second frame may be a sensing switch response frame. The sensing switch response frame is used to respond to / reply to the sensing switch request frame. This embodiment does not limit the specific names of the first frame and the second frame. For ease of description, the following description uniformly uses the sensing switch request frame and the sensing switch response frame.

[0114] The perception switching request frame may carry relevant parameters of the perception switching request, for example, the perception switching request frame may include identification information of the second device, the time of the perception switching process, and at least one of the third device acting as a responder or initiator of a new round of perception measurement after the perception switching.

[0115] It can be understood that the perception switching request frame can be a new frame. For a possible implementation of the perception switching request frame, please refer to Figure 6, which is a structural diagram of a perception switching request frame provided by an embodiment of the present application. As shown in Figure 6, the perception switching request frame may include a category field, a public action / protected dual public action field, a dialog token field, and a first perception switching parameter element field, wherein the first perception switching parameter element field includes an element ID field, a length field, an element ID extension field, a perception switching parameter control field, a perception switching ID field, and an MLD parameter field, wherein the perception switching parameter control field includes a perception switching procedure expiry index subfield, a perception responder subfield, and a reserved subfield.

[0116] The value corresponding to the type field may be as shown in Table 1 below:

[0117] Table 1

[0118] A possible design can be specifically shown in Table 2 below:

[0119] Table 2

[0120] The perception switching identification field includes the identification information of the second device. Specifically: the first device can carry the identifier of the second device in the perception switching identification field to indicate the device that needs to send the perception switching request frame. First, the first device needs to obtain the identifier of the second device. The implementation methods of the identifier of the second device include the following situations: The first situation: the first device and the third device negotiate the identifier of the second device. For example, the first device assigns an identifier to the second device, and the assigned perception switching identifier can be recognized by the third device; or the second device sends its own identifier to each device participating in multi-device collaborative transmission (including the first device). The second situation: the identifier of the second device can be the MAC address of the second device, or a 16-bit ID can be generated based on the MAC address of the second device. The third situation: there is a module in the device where the third device is located that corresponds to the second device (this second device is associated with the first device), and the AID of this module is used to identify the second device. The fourth situation: the third device can identify the second device through the BSSID of the second device.

[0121] The Sensing Switch Procedure Expiry Index subfield includes the duration of the sensing switch procedure. For example, the Sensing Switch Procedure Expiry Index subfield may occupy 4 bits and contain an unsigned integer. The value corresponding to the Sensing Switch Procedure Expiry Index may be equal to 2 Sensing Switch Procedure Expiry Exponent + 8ms, meaning that the duration of the sensing switch procedure is 2 Sensing Switch Procedure Expiry Exponent + 8ms. If no data is transmitted after this time, the sensing switch procedure terminates.

[0122] The Perception Responder subfield includes whether the target device (third device) serves as the responder or initiator of a new round of perception measurements after the perception handover. For example, if the Perception Responder subfield is 1, it may indicate that the third device serves as the responder of a new round of perception measurements after the perception handover, and if the Perception Responder subfield is 0, it may indicate that the third device serves as the initiator of a new round of perception measurements after the perception handover.

[0123] In a possible implementation, the sensing switch parameter control field further includes a sensing switch request / response subfield and an enable / invocation MLO subfield.

[0124] The Perception Handover Request / Response subfield may be used to indicate that the Perception Handover Parameter Element field is included in a Perception Handover Request frame or a Perception Handover Response frame. The Perception Handover Request / Response subfield is optional and may be implemented as follows: For example, if the Perception Handover Request / Response subfield is 1, it may indicate that the Perception Handover Parameter Element field is included in a Perception Handover Request frame, and if the Perception Handover Request / Response subfield is 0, it may indicate that the Perception Handover Parameter Element field is included in a Perception Handover Response frame.

[0125] The Enable MLO subfield indicates whether to enable multilink operation. The Enable MLO subfield is optional and can be implemented as follows: For example, setting the Enable MLO subfield to 1 indicates that multilink operation is enabled; setting the Enable MLO subfield to 0 indicates that multilink operation is not enabled or supported. The above implementation is only a special case of the Enable MLO subfield and can be flexibly applied to specific situations. There is no restriction on the name of the Enable MLO subfield or the number of bits in this field.

[0126] The MLD parameter field is used to indicate information such as the link device ID and link ID. The Enable MLO subfield can be implemented as follows: For example, when the Enable MLO subfield is 1, it may indicate that the MLD parameter field exists; when the Enable MLO subfield is 0, it may indicate that the MLD parameter field does not exist or is a reserved field.

[0127] The perception switching response frame may carry relevant parameters of the perception switching response, such as the success or failure of the perception switching, the perception information of the third device, the location information of the third device, the time of the perception switching process, and at least one of the third device as a responder or initiator of a new round of perception measurement after the perception switching.

[0128] It is understood that the Perception Handover Response frame can be a new frame. For a possible implementation of the Perception Handover Response frame, please refer to Figure 7, which is a schematic diagram of the structure of a Perception Handover Response frame provided in an embodiment of the present application. As shown in Figure 7, the Perception Handover Response frame may include a Category field, a Public Action / Protected Dual Public Action field, a Dialog Token field, and a Status Code field.

[0129] The status code field is used to indicate the success or failure of the sensor switching. This can be implemented as follows: For example, a status code field of 1 indicates a successful sensor switching, while a status code field of 0 indicates a failed sensor switching. For another example, a status code field of success indicates a successful sensor switching, while a status code field of failure indicates a failed sensor switching.

[0130] A possible implementation method is that the perception switching response frame may also include a second perception switching parameter element field (sensingswitchparameterselement) field. The second perception switching parameter element field is an optional field. The implementation method may be as follows: when the status code field indicates that the perception switching is successful, the second perception switching parameter element field exists; otherwise, the second perception switching parameter element field does not exist.

[0131] The second sensing switch parameter element field includes an element ID field (also known as an element identification code field), a length field, an element ID extension field, a sensing switch parameter control field, a sensing switch ID field (also known as a sensing switch identifier or sensing switch identification code), a location information field, an MLD parameters field, and a neighbor report element field. The sensing switch parameter control field includes a sensing switch procedure expiry exponent subfield, a sensing responder subfield, and a reserved subfield. In one possible implementation, the sensing switch parameter control field also includes a sensing switch request / response subfield and an enable MLO subfield.

[0132] The location information field is used to transmit / carry the location information of the third device. The location information field is optional and can be implemented as follows: The location information field can occupy 18 bytes. The location information field can be expanded based on specific application scenarios. There is no limit on the number of bits occupied by the location information field. If location information is optional, an optional field can be added to supplement it.

[0133] The neighbor report element field is an optional field, and the neighbor report element field can be used to transmit / carry the perception information of the third device.

[0134] In a second possible implementation, the first device may obtain the first information from the third device via a wired connection. For example, see Figure 8, which is another signaling flow chart between devices provided in an embodiment of the present application. As shown in Figure 8, the first device and the third device may communicate via a wired connection, for example, the first device obtaining the first information from the third device.

[0135] The collaboration between the first device and the third device (such as collaboration between multiple APs) can be performed in a wired form or a wireless form, making the communication mode between the devices more flexible.

[0136] S402: The first device sends first information to the second device. Correspondingly, the second device receives the first information from the first device.

[0137] After obtaining the first information, the first device may send the first information to the second device. In one possible implementation, as shown in FIG5 or FIG8 above, the first device may send a third frame to the second device, and the third frame may include the first information.

[0138] For example, the third frame may be a sensing suggestion request frame. The fourth frame may be a sensing suggestion response frame, which is used to respond to / reply to the sensing suggestion request frame. This embodiment does not limit the specific names of the third and fourth frames. For ease of description, the following description will uniformly use the sensing suggestion request frame and the sensing suggestion response frame.

[0139] The perception suggestion request frame may carry relevant parameters of the perception suggestion request, for example, the perception suggestion request frame may include at least one of the location information of the third device, whether the third device enables multi-link perception, the perception information of the third device, the third device as a responder or initiator of a new round of perception measurement after perception switching, and the number of third devices recommended to be able to perform perception switching with the second device.

[0140] It can be understood that the perception suggestion request frame can be a new frame. For a possible implementation of the perception suggestion request frame, please refer to Figure 9, which is a structural diagram of a perception suggestion request frame provided by an embodiment of the present application. As shown in Figure 9, the perception suggestion request frame may include a category field, a public action / protected dual public action field, a dialog token field, and a perception suggestion parameter element field, wherein the perception suggestion parameter element field includes an element ID field, a length field, an element ID extension field, a perception suggestion parameter control field, and a perception suggestion equipment's information field, wherein the perception suggestion parameter control field includes a sensing responder subfield, a number of suggested equipment subfield, and a reserved subfield.

[0141] The subfield of the number of recommended devices includes the number of third devices recommended to be capable of perceptually switching with the second device.

[0142] The information field for the perception suggestion device includes information about at least one third device, such as the location information of the third device, whether the third device has multi-link perception enabled, and the perception information of the third device. For an implementation of one of the fields for information about a third device, please refer to FIG10 , which is a schematic diagram of the structure of an information field for a perception suggestion device provided in an embodiment of the present application. As shown in FIG10 , the information field for the perception suggestion device includes a location information field, an enable MLO and MLD parameters field, and a neighbor report element field.

[0143] In one possible implementation, the Enable MLO and MLD parameter field includes whether the third device has enabled multi-link awareness, and may also include information such as the link device ID and link ID. For a possible implementation of the Enable MLO and MLD parameter field, please refer to Figure 11, which is a schematic diagram of the structure of the Enable MLO and MLD parameter field provided in an embodiment of the present application. As shown in Figure 11, the Enable MLO and MLD parameter field includes an MLD ID subfield, a link ID subfield, a BSS parameter change count subfield, an all update included subfield, a disabled link indication subfield, and an Enable MLO subfield.

[0144] In one possible implementation, the sensing suggestion parameter control field also includes a sensing suggestion request / response subfield. The sensing suggestion request / response subfield can be used to indicate that the sensing suggestion parameter element field is included in a sensing suggestion request frame or a sensing suggestion response frame. The sensing suggestion request / response subfield is an optional field and can be implemented as follows: for example, if the sensing suggestion request / response subfield is 1, it can indicate that the sensing suggestion parameter element field is included in the sensing suggestion request frame, and if the sensing suggestion request / response subfield is 0, it can indicate that the sensing suggestion parameter element field is included in the sensing suggestion response frame.

[0145] Among them, a possible design can be specifically shown in Table 3 below:

[0146] Table 3

[0147] The perception suggestion response frame may carry relevant parameters of the perception suggestion response, such as status indication information, location information of the third device, whether the third device enables multi-link perception, perception information of the third device, the third device as a responder or initiator of a new round of perception measurement after perception switching, and at least one of the number of third devices recommended for perception switching with the second device. The status indication information is used to indicate whether the second device successfully receives the first information.

[0148] It is understood that the perception suggestion response frame can be a new frame. For a possible implementation of the perception suggestion response frame, please refer to Figure 12, which is a structural diagram of a perception suggestion response frame provided by an embodiment of the present application. As shown in Figure 12, the perception suggestion response frame may include a category field, a public action / protected dual public action field, a dialog token field, and a status code field.

[0149] The status code may include status indication information, which is used to indicate whether the second device successfully received the first information. This may be implemented as follows: For example, if the status code field is 1, it may indicate that the second device successfully received the first information; if the status code field is 0, it may indicate that the second device failed to successfully receive the first information. For another example, if the status code field is success, it may indicate that the second device successfully received the first information; otherwise, it indicates that the second device failed to successfully receive the first information.

[0150] In one possible implementation, the sensing handover response frame may further include a sensing suggestion parameter element field, wherein the sensing suggestion parameter element field includes an element ID field, a length field, an element ID extension field, a sensing suggestion parameter control field, and a sensing suggestion equipment's information field, wherein the sensing suggestion parameter control field includes a sensing responder subfield, a number of suggested equipment subfield, and a reserved subfield. In one possible implementation, the sensing suggestion parameter control field also includes a sensing suggestion request / response subfield.

[0151] The perception suggestion parameter element field is an optional field, and can be implemented as follows: when the status code field indicates that the second device successfully receives the first information, the perception suggestion parameter element field exists; otherwise, the perception suggestion parameter element field does not exist.

[0152] A possible design of the public action field values ​​(publicactionfieldvalues) of the four frames mentioned above can be seen in Table 4 below:

[0153] Table 4

[0154] In a possible implementation, the public operation field value may also be located in a protected dual public action frame (protected dual of public action frames), as shown in Table 5 below:

[0155] Table 5

[0156] S403: The second device determines a target device for perception switching according to the first information.

[0157] After receiving the first information from the first device, the second device can determine a target device for the perceptual handover based on the perceptual information of at least one third device capable of perceptual handover with the second device included in the first information, wherein the target device is a device among the at least one third device.

[0158] Furthermore, the above steps may also include:

[0159] A perception measurement is performed between the second device and the third device. For example, as shown in Figure 5 or Figure 8 above, the second device and the third device can implement the perception measurement through a perception measurement request and a perception measurement response. In one possible implementation, before the perception measurement, if the first device and the third device are already associated, the method may further include the second device and the third device being able to implement reassociation through a reassociation request and a reassociation response. It can be understood that the third device is the target device of the perception switching determined by the second device.

[0160] In an embodiment of the present application, during the WLAN perception process, multi-device collaboration can be used to implement perception switching, saving the detection scanning process. For example, if the perception accuracy of the first device decreases, information can be exchanged with devices in the device collaboration set to obtain relevant information about devices surrounding the second device and recommend switchable devices in the device collaboration set (such as the first information) to the second device, so that the devices in the device collaboration set can independently select the device to be switched, thereby improving the efficiency of the perception switching process. Moreover, the second device can select a device with a better perception measurement result for perception measurement based on the first information, thereby improving the quality of perception switching.

[0161] In combination with the embodiment of Figure 4 above, a possible implementation method is: the perception measurement between the second device and the third device can be implemented through the first device and the third device, that is, the perception measurement of S403 can be implemented in the perception switching of S401 and S402, and through the collaboration of the first device and the third device, the first device can replace the second device and the third device to perform perception measurement. Specifically, please refer to Figures 13 and 14. Figures 13 and 14 are another signaling flow chart between devices provided in the embodiment of the present application. Different from Figures 5 and 8, Figures 13 and 14 do not require separate perception measurement requests and perception measurement responses. The perception switching and perception measurement stages are realized by carrying parameters related to perception measurement through at least one of the first frame, the second frame, the third frame and the fourth frame, or by carrying parameters related to perception measurement through wired collaboration and at least one of the third frame and the fourth frame.

[0162] As shown in Figure 13, illustratively, the first frame may be a sensing switch measurement request frame, and the second frame may be a sensing switch measurement response frame. The sensing switch measurement response frame is used to respond to / reply to the sensing switch measurement request frame. This embodiment does not limit the specific names of the first frame and the second frame. For ease of description, the following description uniformly uses the sensing switch measurement request frame and the sensing switch measurement response frame.

[0163] It can be understood that the perception switching measurement request frame can be modified on the basis of the perception measurement request frame. For a possible implementation of the perception switching measurement request frame, please refer to Figure 15, which is a structural diagram of a perception switching measurement request frame provided by an embodiment of the present application. As shown in Figure 15, the perception switching measurement request frame may include a category field, a public action / protected dual public action field, a dialog token field, a measurement session ID indication field, and a perception switching measurement parameter element field, wherein the perception switching measurement parameter element field includes an element ID field, a length field, an element ID extension field, a perception switching parameter control field, a perception measurement parameter field, and a perception switching identifier field. In a possible implementation, the perception switching measurement parameter element field may also include an MLD parameter field.

[0164] The perception measurement parameter field includes the first perception measurement parameter. The description of the remaining fields can refer to the description in the above step S401 and will not be repeated here.

[0165] The perception switching measurement response frame may be modified on the basis of the perception measurement response frame. For a possible implementation of the perception switching measurement response frame, please refer to Figure 16, which is a structural diagram of a perception switching measurement response frame provided by an embodiment of the present application. As shown in Figure 16, the perception switching measurement response frame may include a category field, a public action / protected dual public action field, a dialog token field, a measurement session identification indication field, a status code field, and a perception switching measurement parameter element field, wherein the perception switching measurement parameter element field includes an element ID field, a length field, an element ID extension field, a perception switching parameter control field, a perception switching identification field, a location information field, a neighbor report element field, and a perception subelement field.

[0166] The status code field includes indication information indicating whether the third device accepts the first perception measurement parameter. This can be implemented as follows: For example, a status code field of 1 may indicate acceptance of the first perception measurement parameter, while a status code field of 0 may indicate rejection of the first perception measurement parameter. For another example, a status code field of success may indicate acceptance of the first perception measurement parameter, while otherwise, rejection of the first perception measurement parameter.

[0167] When the status code field indicates that the first perception measurement parameter is accepted, the perception switching measurement parameter element field may not include the perception measurement parameter field. When the status code field indicates that the first perception measurement parameter is not accepted, the perception switching measurement parameter element field may include the perception measurement parameter field, and the perception measurement parameter field includes the second perception measurement parameter, and the second perception parameter is determined by the third device.

[0168] Furthermore, the perception handover measurement parameter element field may also include an MLD parameter field. For descriptions of the remaining fields, reference may be made to the description in step S401 above, which will not be repeated here.

[0169] As shown in Figures 13 and 14, illustratively, the third frame may be a sensing suggestion request frame, and the fourth frame may be a sensing suggestion response frame, which is used to respond to / reply to the sensing suggestion request frame.

[0170] Compared to the perception suggestion request frame of FIG9 , the first information included in the perception suggestion request frame may further include perception measurement parameters of the third device. The perception suggestion request frame includes an information field for the perception suggestion device, and the information field for the perception suggestion device includes the first information. For a possible implementation of the information field for the perception suggestion device, please refer to FIG17 , which is a structural diagram of the information field of another perception suggestion device provided in an embodiment of the present application. As shown in FIG17 , the information field for the perception suggestion device includes a measurement session ID indication field, a location information field, an enable MLO and MLD parameters field, and a neighbor report element field.

[0171] In one possible implementation, the perception suggestion device information field may further include a perception measurement parameters field, where the perception measurement parameters field includes the perception measurement parameters of the third device. This implementation may be as follows: if the perception measurement parameters of the third device are not included, it may indicate that the third device accepts the perception measurement parameters previously provided by the second device; if the perception measurement parameters of the third device are included, it may indicate that the third device does not accept the perception measurement parameters previously provided by the second device and provides new perception measurement parameters to the second device.

[0172] Compared to the perception suggestion response frame of Figure 12, as shown in Figure 18, Figure 18 is a schematic diagram of the structure of another perception suggestion response frame provided in an embodiment of the present application. As shown in Figure 18, the perception suggestion response frame may further include a measurement session ID indication field. The measurement session ID indication field is used to indicate the session for performing measurements with the third device. The description of the remaining identical fields can refer to the description in the above step S401 and will not be repeated here.

[0173] In an embodiment of the present application, based on the use of multi-device collaboration to achieve perception switching, perception measurement parameters can also be exchanged during the perception switching stage, so that the second device and the third device can subsequently perform a perception measurement session process, thereby not only improving the efficiency of the perception switching process, but also enabling the second device to select a device with a better perception measurement result for perception measurement based on the first information, thereby improving the quality of the perception switching and improving the perception measurement efficiency.

[0174] The above content describes the method provided by the present application. In order to facilitate better implementation of the above scheme of the embodiment of the present application, the embodiment of the present application also provides a corresponding device.

[0175] In the embodiment of the present application, the functional modules of the communication device can be divided according to the above method example. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated modules can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in the embodiment of the present application is schematic and is only a logical functional division. In actual implementation, there may be other division methods.

[0176] Please refer to Figure 19, which is a schematic diagram of the structure of a communication device provided in an embodiment of the present application. The communication device can be a first device, a module (e.g., a chip or processor) in the first device, or a logic module or software that can implement all or part of the functions of the first device. As shown in Figure 19, the communication device 1900 includes at least: an acquisition unit 1901 and a transceiver unit 1902; wherein:

[0177] An acquiring unit 1901 is configured to acquire first information, where the first information includes perception information of at least one third device that can perceive and switch with the second device;

[0178] The transceiver unit 1902 is configured to send first information to the second device.

[0179] In one embodiment, the perception information includes at least one of a basic service set identifier (BSSID) of the third device, working channel information, and whether the third device has perception capability.

[0180] In one embodiment, the acquiring unit 1901 acquires the first information, specifically for:

[0181] Sending a first frame to the third device, where the first frame is used to request perception switching of the second device;
