[0037] This disclosure presents a communication method, communication device, and communication system.

[0038] In a first aspect, embodiments of this disclosure provide a communication method applied to a first access point (AP), the method comprising:

[0039] A first radio frame is determined; wherein the first radio frame is used to request the establishment of a multi-AP coordination mechanism with the second AP; the first radio frame identifies: the type information of the multi-AP coordination mechanism, and / or the parameter information of the multi-AP coordination mechanism;

[0040] Send the first wireless frame.

[0041] In the above embodiments, the establishment process of the multi-AP coordination mechanism is further improved by having the first AP generate and send a radio frame containing specific type and parameter information when establishing the multi-AP coordination mechanism. This method, by clearly identifying the type and related parameters of the coordination mechanism, allows different types of coordination mechanisms to be flexibly configured and selected according to actual network needs, thus meeting UHR requirements.

[0042] In conjunction with some embodiments of the first aspect, in some embodiments, the first wireless frame includes at least one of the following:

[0043] The first information bit identifies the type information of the multi-AP coordination mechanism;

[0044] The first information field identifies the parameter information of the multi-AP coordination mechanism;

[0045] The second information field identifies the Time Synchronization Function (TSF) information of the first AP.

[0046] In the above embodiments, by including a first information bit, a first information field, and a second information field in the first radio frame, the type of the multi-AP coordination mechanism, related parameters, and the time synchronization function (TSF) information of the first AP can be effectively identified. This enables the second AP to accurately understand and execute the instructions of the first AP, thereby ensuring that the multi-AP coordination mechanism can be correctly configured and synchronized.

[0047] In conjunction with some embodiments of the first aspect, in some embodiments, the first information bit set as a first parameter value identifies the type of the multi-AP coordination mechanism as Co-RTWT (Coordinated Real-Time Wireless Transmission); and / or

[0048] The first information bit, set to the second parameter value, identifies the type of the multi-AP coordination mechanism as Coordinated Beamforming (Co-BF); and / or

[0049] The first information bit, set to the third parameter value, identifies the type of the multi-AP coordination mechanism as power control coordination C-SR based on transmission opportunity (TXOP).

[0050] In the above embodiments, by setting different first information bit parameter values ​​in the first radio frame, different types of multi-AP coordination mechanisms (such as Co-RTWT, Co-BF, and Co-SR based on transmission opportunity TXOP power control) can be identified, and the type of coordination mechanism used can be accurately specified.

[0051] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0052] In the case where the type of the multi-AP coordination mechanism includes Co-RTWT, the first information field indicates the target wake-up time scheduling (RTWT) schedule information; and / or

[0053] In the case where the multi-AP coordination mechanism includes Co-BF, the first information field identifies the Co-BF to be established as either Joint Beamforming (CoBF) or Disjoint Beamforming (DBF).

[0054] In the case where the multi-AP coordination mechanism includes C-SR, the first information field indicates Spatial Reuse parameter information.

[0055] In the above embodiments, the first information field carries different specific information according to different multi-AP coordination mechanism types, thereby enabling the first AP to transmit relevant control parameters according to the requirements of the coordination mechanism.

[0056] In conjunction with some embodiments of the first aspect, in some embodiments, when the type of the multi-AP coordination mechanism includes Co-RTWT, the first information field includes a first information field that identifies the number of RTWT schedule items.

[0057] In the above embodiments, when the type of the multi-AP coordination mechanism includes Co-RTWT, by setting a first information field in the first information field to identify the number of RTWT schedule items, accurate description and efficient management of scheduling resources can be achieved. This design can effectively reduce signaling overhead in the coordination mechanism.

[0058] In conjunction with some embodiments of the first aspect, in some embodiments, when the multi-AP coordination mechanism includes Co-BF, the first information field includes a first identifier bit, which identifies at least one of the spatial flow (SS) information corresponding to the Joint BF or the disjoint BF and the basic service set (BSS) color information.

[0059] In the above embodiments, the BSS color information of different spatial streams and basic service sets can be effectively identified and distinguished, thereby enhancing the coordination between APs, reducing interference, and improving the stability and reliability of signal transmission.

[0060] In conjunction with some embodiments of the first aspect, in some embodiments, the Spatial Reuse parameter information includes at least one of the following:

[0061] Packet detection includes PD transmission power information, receive power threshold information, and BSS color information.

[0062] In the above embodiments, by introducing parameter information of these multi-AP coordination mechanisms, the cooperation between APs can be adjusted more accurately, the space reuse strategy can be optimized, and the interference between different APs can be reduced.

[0063] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0064] Receive a second radio frame; wherein the second radio frame is used to respond to the first radio frame; the second radio frame indicates whether the second AP accepts the multi-AP coordination mechanism establishment request of the first AP.

[0065] In the above embodiment, the content of the second radio frame indicates whether the second AP has accepted the multi-AP coordination mechanism establishment request sent by the first AP. This process ensures that the first AP can promptly understand the response of the second AP and thus determine whether the coordination mechanism establishment can continue. This avoids resource waste or unnecessary operations caused by failed coordination requests, while improving the stability and efficiency of the entire network.

[0066] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0067] When the second radio frame indicates that the second AP has accepted the multi-AP coordination mechanism establishment request from the first AP, the second radio frame includes at least one of the following:

[0069] The third identification information carries the identification information assigned by the second AP to the first AP;

[0070] The fourth identification information carries the BSS color information assigned by the second AP to the first AP.

[0071] In the above embodiments, by explicitly transmitting session identifiers and assigned identifier information, the first AP and the second AP can better manage and distinguish different sessions when establishing a multi-AP coordination mechanism. This not only ensures the correct establishment of sessions but also enhances the collaborative work between APs, enabling the rational allocation of network resources and reducing interference.

[0072] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0073] In the case where the multi-AP coordination mechanism includes Co-BF, the third identification information indicates that channel measurement is triggered in Co-BF by the trigger frame sent by the second AP.

[0074] In the above embodiments, it can be ensured that in the Co-BF mechanism, the second AP can actively trigger channel measurement, thereby helping to optimize the signal transmission direction and coverage.

[0075] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0076] In cases where the second radio frame indicates that the second AP rejects the first AP's multi-AP coordination mechanism establishment request, the second radio frame further includes:

[0077] The fifth identification information identifies that the RTWT schedule time period of the multi-AP coordination mechanism established by the first AP overlaps or partially overlaps with the RTWT schedule time period of the second AP.

[0078] In the above embodiments, even if the second AP refuses to establish a multi-AP coordination mechanism, the second AP will still inform the first AP of the status of its RTWT scheduling time period, thereby helping the first AP to better understand the cause of the conflict or resource competition.

[0079] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0080] A third radio frame is determined, the third radio frame identifying the capability information of the first AP to support the multi-AP coordination mechanism;

[0141] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0142] As shown in Figure 1, the communication system 100 includes a first access point (AP) 101 and a second AP 102.

[0143] In some embodiments, the first AP 101 and the second AP 102 can be access points for mobile terminals to access a wired network. An AP acts as a bridge connecting a wired network and a wireless network, its main function being to connect various wireless network clients together and then connect the wireless network to the Ethernet. Specifically, an AP can be a terminal device or network device with a wireless fidelity chip. Optionally, the AP can support various WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as the next-generation 802.11 protocol, but is not limited to these.

[0144] Optionally, in this embodiment of the disclosure, the first AP 101 and the second AP 102 can be devices that support multiple links, for example, they can be represented as Access Point Multi-Link Device (AP MLD); AP MLD can represent an access point that supports multi-link communication functions. For example, in this embodiment of the disclosure, "link" can represent connection or link; in various embodiments, connection and link can be interchanged.

[0145] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0146] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0147] The embodiments disclosed herein can be applied to Wireless Local Area Networks (WLANs), such as LANs using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component. An BSS network consists of site devices with some association within a specific coverage area. One type of association is where sites communicate directly with each other in a self-organizing network; this is called an Independent Basic Service Set (IBSS). Another more common scenario is that in a BSS network, there is only one central site dedicated to managing the BSS, called the Access Point (AP) device, and all other STAs in the network are associated with it. Other sites in the BSS network that are not the central site are called terminals, also known as non-AP STAs; terminals and non-AP STAs are collectively referred to as STAs. When describing STAs, it is not necessary to distinguish between terminals and non-AP STAs. Within the same BSS network, due to distance, transmission power, etc., a STA cannot detect other STAs that are far away; they are each other's hidden nodes.

[0148] Figure 2 is one of the interactive schematic diagrams of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes:

[0149] Step 201, the first AP 101 determines the first radio frame; wherein, the first radio frame is used to request the establishment of a multi-AP coordination mechanism with the second AP 102; the first radio frame identifies: the type information of the multi-AP coordination mechanism, and / or, the parameter information of the multi-AP coordination mechanism.

[0150] In the Unified Response Network (UHR), a multi-AP coordination method is proposed to improve the transmission reliability and throughput of the wireless network. Specifically, a general multi-AP coordination framework is defined, supporting various coordination schemes, including but not limited to a transmission opportunity-based power control coordination mechanism (TXOP-based with power control, Co-SR: Co-Coordinated Spatial Reuse), a coordinated beamforming mechanism (Co-BF), a coordinated time division multiple access mechanism (Co-TDMA), and a coordinated restricted target time wakeup mechanism (Co-RTWT). This framework enables the implementation of a multi-AP coordination discovery procedure and a multi-AP coordination agreement negotiation procedure, providing a unified operational basis for different coordination schemes, thereby promoting efficient collaborative work among APs. However, the existing multi-AP coordination mechanism in the UHR is not yet perfect. To achieve more efficient and reliable multi-AP collaborative operation, further signaling definitions and process optimizations are needed to improve the multi-AP coordination establishment mechanism.

[0151] In this embodiment, the first AP can be a requesting AP, an initiating AP, or a coordinating AP that establishes a multi-AP coordination mechanism. The first radio frame can be a multi-AP coordination mechanism request frame, used to request the establishment of a multi-AP coordination mechanism with the second AP / coordinated AP. This radio frame includes type information and / or parameter information of the multi-AP coordination mechanism. Specifically, the type information indicates the coordination method, while the parameter information provides specific configuration requirements. This mechanism optimizes the cooperation of multiple APs, reduces interference, and meets UHR requirements.

[0152] Step 202: The first AP 101 sends the first wireless frame; correspondingly, the second AP 102 receives the first wireless frame.

[0153] In this embodiment, the first AP sends a first wireless frame to the second AP. Upon receiving the frame, the second AP can understand the type and parameter information of the multi-AP coordination mechanism transmitted by the first AP. This process ensures that the second AP can obtain the necessary information in a timely manner, thereby participating in the establishment of the multi-AP coordination mechanism and improving the establishment process of the multi-AP coordination mechanism.

[0162] Figure 3 is a second interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3, the embodiments of the present disclosure relate to a communication method, which includes:

[0163] Step 301, the first AP 101 determines the first radio frame; wherein, the first radio frame is used to request the establishment of a multi-AP coordination mechanism with the second AP 102; the first radio frame identifies: the type information of the multi-AP coordination mechanism, and / or, the parameter information of the multi-AP coordination mechanism.

[0164] In this embodiment of the disclosure, the first AP requests to establish a multi-AP coordination mechanism with the second AP by determining a first radio frame. The first radio frame contains type information and / or parameter information of the multi-AP coordination mechanism. The type information describes the specific coordination method (e.g., Co-SR, Co-BF, Co-TDMA, Co-RTWT, etc.), while the parameter information provides specific configuration requirements.

[0165] In some embodiments, the first wireless frame includes at least one of the following:

[0166] The first information bit identifies the type information of the multi-AP coordination mechanism;

[0167] The first information field identifies the parameter information of the multi-AP coordination mechanism;

[0168] The second information field identifies the time synchronization function (TSF) information of the first AP.

[0169] In this embodiment of the disclosure, the first wireless frame includes at least one of the following: a first information bit for identifying the type of multi-AP coordination mechanism, a first information field for describing the specific parameters of the mechanism, and a second information field for identifying the first AP time synchronization function (TSF) information. This design ensures that the establishment of the multi-AP coordination mechanism has a comprehensive information foundation. Specifically, the first information bit can specify the type of coordination mechanism (e.g., Co-SR, Co-BF, Co-TDMA, Co-RTWT, etc.), the first information field provides specific parameter information for fine-grained control, and the TSF information in the second information field supports time synchronization functions (e.g., ensuring that the requesting AP and the responding AP are synchronized in time in Co-RTWT coordination).

[0170] In some embodiments, the first information bit set to a first parameter value identifies the type of the multi-AP coordination mechanism as Co-RTWT; and / or

[0171] The first information bit, set to the second parameter value, identifies the type of the multi-AP coordination mechanism as Coordinated Beamforming (Co-BF); and / or

[0172] The first information bit, set to the third parameter value, identifies the type of the multi-AP coordination mechanism as power control coordination C-SR based on transmission opportunity (TXOP).

[0173] In this embodiment of the disclosure, the first information bit in the first wireless frame identifies the type of multi-AP coordination mechanism through different parameter values. For example, setting it to the first parameter value indicates Co-RTWT, which is used to ensure time synchronization and transmission stability in real-time transmission scenarios; setting it to the second parameter value indicates Co-BF, which is used to optimize signal coverage and spatial separation, and improve the communication quality of multiple devices; setting it to the third parameter value indicates C-SR, which is used to optimize channel resource utilization through transmission opportunities and power adjustments. This design, which directly identifies the coordination mechanism type through information bits, makes the selection of multi-AP cooperation type more intuitive and efficient.

[0174] In some embodiments, the method further includes the following cases one through three:

[0175] Scenario 1: When the type of the multi-AP coordination mechanism includes Co-RTWT, the first information field indicates the target wake-up time scheduling (RTWT) schedule information.

[0176] Optionally, when the type of the multi-AP coordination mechanism includes Co-RTWT, the first information field includes a first information field that identifies the number of RTWT schedule items.

[0177] In this embodiment of the disclosure, when the multi-AP coordination mechanism type is Co-RTWT, the first information field carries scheduling information (RTWT schedule) for the target wake-up time limit (RTWT) to ensure coordinated time management between the requesting AP and the responding AP. This information may include multiple RTWT scheduling items; therefore, the first information field also contains an information field to identify the number of RTWT scheduling items. For example, the number of scheduling items can be identified using three bits: 000: no RTWT schedule item; 001: 1 RTWT schedule item; 010: 2 RTWT schedule items; 011: 3 RTWT schedule items; 100: 4 RTWT schedule items; 101: 5 RTWT schedule items; 110: 6 RTWT schedule items; 111: 7 RTWT schedule items. By setting such bits, the first AP can clearly identify the number of RTWT schedule items that need to be processed by the second AP. Compared with the existing technology that only identifies items containing at least one RTWT schedule item, this significantly improves the accuracy and flexibility of scheduling information transmission, thereby optimizing resource allocation and time management.

[0178] Scenario 2: When the multi-AP coordination mechanism includes Co-BF, the first information field identifies the Co-BF to be established as a Joint Beamforming (Joint BF) or Disjoint Beamforming (Disjoint BF), and carries at least one of the following: Spatial Stream (SS) information and Basic Service Set (BSS) color information corresponding to the Joint BF or Disjoint BF.

[0179] In the embodiments of the present disclosure, when the multi-AP coordination mechanism type is Co-BF, the first information field identifies whether the beamforming type requested to be established is Joint Beamforming (Joint BF) or Disjoint Beamforming (disjoint BF). Among them, Joint BF means that multiple APs work together, share signal processing resources, and cooperate to adjust the direction and shape of their transmission beams to enhance the signal coverage and transmission efficiency; disjoint BF means that each AP independently adjusts its beam, and does not share information or coordinate signal processing with each other. In addition, the first information field may further include a first identification bit, and the first identification bit identifies the Spatial Stream (SS) information and Basic Service Set Color (BSS color) information related to beamforming, supporting precise coordination of beam resources among multiple APs. This design can optimize the spatial reuse performance of the signal, enhance the coverage and communication quality, and reduce interference at the same time.

[0180] When the multi-AP coordination mechanism includes C-SR, the first information field indicates the Spatial Reuse parameter information; among them, the Spatial Reuse parameter information includes at least one of the transmission power information of packet detection (PD), the received power threshold information, and the BSS color information.

[0181] In the embodiments of the present disclosure, when the multi-AP coordination mechanism type is C-SR, the first information field carries the parameter information of Spatial Reuse, including the transmission power information of packet detection (PD), the received power threshold information, and the BSS color information, etc. These parameters support the AP to achieve more efficient power control and interference management when sharing channel resources, thereby improving the transmission efficiency and channel utilization rate. Especially in a high-density network environment, it can effectively reduce interference and improve the overall performance.

[0182] Step 302, the first AP 101 sends the first wireless frame; correspondingly, the second AP​​​​​​​

[0185] In this embodiment, the second AP generates a second wireless frame in response to the received first wireless frame. The main function of this second wireless frame is to confirm with the first AP whether it accepts the multi-AP coordination mechanism establishment request. For example, the second wireless frame includes a status flag to indicate whether the first AP's request for multi-AP coordination mechanism establishment is accepted or rejected. For instance, a status flag value of "1" indicates that the second AP accepts the request; a status flag value of "0" indicates that the second AP rejects the request. This design can quickly and clearly convey the status of the coordination request, ensuring efficient and clear information exchange between the two APs, thus providing a basis for subsequent network coordination operations, avoiding unnecessary delays or incorrect network configurations, and improving the responsiveness and stability of the entire system.

[0186] Step 304: The second AP 102 sends the second wireless frame; correspondingly, the first AP 101 receives the second wireless frame.

[0187] In this embodiment, the second AP sends a second radio frame to the first AP as a response to the first radio frame. Upon receiving the second radio frame, the first AP can determine from its content whether the second AP accepts its request to establish a multi-AP coordination mechanism. This process ensures information transmission and confirmation of the coordination status between the two, providing a clear basis for subsequent multi-AP cooperation or adjustments.

[0188] In some embodiments, the method further includes:

[0189] When the second radio frame indicates that the second AP has accepted the multi-AP coordination mechanism establishment request from the first AP, the second radio frame includes at least one of the following:

[0190] The second identification information carries at least one session identifier between the first AP and the second AP;

[0191] The third identification information carries the identification information assigned by the second AP to the first AP;

[0192] The fourth identification information carries the BSS color information assigned by the second AP to the first AP.

[0193] In this embodiment, when the second AP accepts the multi-AP coordination mechanism establishment request proposed by the first AP, the second radio frame not only identifies this acceptance status but may also contain second identification information and / or third identification information. The second identification information carries at least one session identifier requested by the first AP to establish a coordination session with the second AP, indicating that the coordination session between the first and second APs has been established or is ready. Each session identifier corresponds to an independent coordination process; for example, if multiple RTWT scheduling items are involved, each scheduling item will have a corresponding session identifier. The third identification information carries the identification information assigned to the first AP; the fourth identification information carries the BSS color information assigned to the first AP. This information helps to accurately identify and distinguish each AP in multi-AP cooperation, and optimize signal coordination and interference management. Especially in Co-BF scenarios, the second AP can better perform channel measurement and beam adjustment through the BSS color information. Through this information transmission, the second AP can explicitly confirm the coordination request to the first AP and provide the necessary session and identification information, laying the foundation for subsequent efficient cooperation and enhancing the system's flexibility and reliability.

[0194] In some embodiments, the method further includes:

[0195] In the case where the multi-AP coordination mechanism includes Co-BF, the third identification information indicates that channel measurement is triggered in Co-BF by the trigger frame sent by the second AP.

[0196] Specifically, when the second AP accepts the first AP's request to establish a multi-AP coordination mechanism (Co-BF), the third identification information indicates that the second AP initiates the channel measurement process by sending a trigger frame. Through this mechanism, the system can manage channel resources more efficiently, reduce interference, and improve overall network performance in a multi-AP environment.

[0197] In some embodiments, the method further includes:

[0198] If the second radio frame indicates that the second AP has rejected the first AP's request to establish a multi-AP coordination mechanism, the second radio frame further includes:

[0199] The fifth identification information identifies that the RTWT schedule time period of the multi-AP coordination mechanism established by the first AP overlaps or partially overlaps with the RTWT schedule time period of the second AP.

[0200] Optionally, when the second AP rejects the first AP's request to establish a multi-AP coordination mechanism, the second radio frame includes a fifth identification information, indicating whether the RTWT schedule time period established by the first AP overlaps or partially overlaps with the RTWT schedule time period of the second AP. Specifically, the fifth identification information can convey the reason for rejection to the first AP, that is, the time schedule proposed by the first AP conflicts with the existing schedule of the second AP. Providing this information not only clearly explains the reason for rejection, but also provides the first AP with a basis for adjusting the time schedule, so as to avoid overlap or conflict in subsequent requests, optimize the scheduling arrangement, and thus improve the coordination and resource utilization efficiency of the entire network.

[0201] The communication method involved in the embodiments of this disclosure may include at least one of steps 301 to 304. For example, step 301 may be implemented as a standalone embodiment, step 302 may be implemented as a standalone embodiment, step 303 may be implemented as a standalone embodiment, step 304 may be implemented as a standalone embodiment, steps 301+302 may be implemented as standalone embodiments, and steps 303+304 may be implemented as standalone embodiments.

[0202] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0203] Figure 4 is a third interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 4, the embodiments of the present disclosure relate to a communication method, which includes:

[0204] In step 401, the first AP 101 and the second AP 102 identify the capability information supporting the multi-AP coordination mechanism through the third radio frame and the fourth radio frame.

[0205] Before the first AP sends the first wireless frame, the method further includes:

[0206] A third radio frame is determined, the third radio frame identifying the capability information of the first AP to support the multi-AP coordination mechanism;

[0207] The third wireless frame is sent.

[0208] In this embodiment, the first AP determines a third radio frame before sending the first radio frame. This third radio frame identifies the first AP's capabilities in multi-AP coordination mechanisms. In other words, the third radio frame conveys the first AP's capabilities in multi-AP coordination mechanisms to the second AP, such as whether it supports different types of coordination mechanisms like Co-RTWT, Co-BF, or C-SR. Next, the first AP sends this third radio frame to communicate its capabilities to the second AP. In this way, the second AP can understand the first AP's supported capabilities after receiving the third radio frame, and thus decide whether to continue negotiating or establish a multi-AP coordination mechanism.

[0209] In some embodiments, before the second AP receives the first radio frame, the method further includes:

[0210] A fourth radio frame is determined; the fourth radio frame identifies the capability information of the second AP to support the multi-AP coordination mechanism;

[0211] The fourth wireless frame is sent.

[0212] In this embodiment, the second AP first determines a fourth radio frame before receiving the first radio frame. This fourth radio frame identifies the second AP's capabilities in multi-AP coordination mechanisms, similar to the operation of the first AP. The fourth radio frame conveys the second AP's capabilities in multi-AP coordination mechanisms to the first AP, such as whether it supports different types of coordination mechanisms like Co-RTWT, Co-BF, or C-SR. Then, the second AP sends the fourth radio frame, transmitting its capability information to the first AP. This allows the first AP to understand the second AP's supported capabilities upon receiving the fourth radio frame. Through this information exchange, the first and second APs can mutually confirm whether a multi-AP coordination mechanism can be established, providing necessary support for subsequent cooperation and resource allocation.

[0213] In this embodiment, the first AP and the second AP identify their respective supported multi-AP coordination mechanism capabilities by sending a third radio frame and a fourth radio frame. This capability information specifically covers different types of multi-AP coordination mechanisms, such as Co-RTWT, Co-BF, and C-SR. It should be noted that the order in which the first AP sends the third radio frame and the second AP sends the fourth radio frame is not critical. Through this interaction of capability identifiers, the system can coordinate and allocate resources more effectively, avoiding cooperation failures caused by incompatible mechanisms, and improving cooperation efficiency and network performance in a multi-AP environment.

[0214] Step 402, the first AP 101 determines the first radio frame; wherein, the first radio frame is used to establish a multi-AP coordination mechanism with the second AP 102; the first radio frame identifies: the type information of the multi-AP coordination mechanism, and / or, the parameter information of the multi-AP coordination mechanism.

[0215] In this embodiment of the disclosure, the first AP requests to establish a multi-AP coordination mechanism with the second AP by determining a first radio frame. The first radio frame contains type information and / or parameter information of the multi-AP coordination mechanism. The type information describes the specific coordination method (e.g., Co-SR, Co-BF, Co-TDMA, Co-RTWT, etc.), while the parameter information provides specific configuration requirements.

[0216] Step 403: The first AP 101 sends the first wireless frame; correspondingly, the second AP 102 receives the first wireless frame.

[0217] In this embodiment of the disclosure, the first AP sends a first radio frame, which is used to establish a multi-AP coordination mechanism with the second AP; the first radio frame identifies: the type information of the multi-AP coordination mechanism, and / or the parameter information of the multi-AP coordination mechanism, to meet UHR requirements.

[0218] Step 404, the second AP 102 determines the second radio frame; wherein, the second radio frame is used to respond to the first radio frame; the second radio frame indicates whether the second AP accepts the multi-AP coordination mechanism establishment request of the first AP.

[0219] The second AP generates a second radio frame in response to the first radio frame. The main function of this second radio frame is to confirm with the first AP whether it accepts the request to establish a multi-AP coordination mechanism.

[0220] Step 405, the second AP 102 sends the second wireless frame; correspondingly, the first AP 101 receives the second wireless frame.

[0221] In this embodiment, the second AP sends a second radio frame to the first AP as a response to the first radio frame. Upon receiving the second radio frame, the first AP can determine from its content whether the second AP accepts its request to establish a multi-AP coordination mechanism. This process ensures information transmission and confirmation of the coordination status between the two, providing a clear basis for subsequent multi-AP cooperation or adjustments.

The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
