[0116] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0117] As shown in FIG1 , a communication system 100 includes a first access point (AP) 101 and a second AP 102 .

[0118] In some embodiments, the first AP 101 and the second AP 102 can be access points for mobile terminals to enter a wired network. The AP is equivalent to a bridge connecting a wired network and a wireless network. Its main function is to connect various wireless network clients together and then connect the wireless network to the Ethernet. Specifically, the AP can be a terminal device or a network device with a wireless fidelity chip. Optionally, the AP can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11bn, 802.11bf and 802.11a, as well as support the next generation 802.11 protocol, but is not limited to these.

[0119] In some embodiments, the communication system 100 further includes a plurality of station devices (STAs), which may include, for example, wireless communication chips, wireless sensors, or wireless communication terminals that support WiFi communication functions. Optionally, the wireless communication terminals may include, but are not limited to, at least one of a mobile phone, a wearable device, an IoT device that supports WiFi communication functions, a car with WiFi communication functions, a smart car, a tablet computer, a computer with wireless transceiver functions, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device used in industrial control, a wireless terminal device used in self-driving, a wireless terminal device used in remote medical surgery, a wireless terminal device used in a smart grid, a wireless terminal device used in transportation safety, a wireless terminal device used in a smart city, and a wireless terminal device used in a smart home.

[0120] Specifically, the site device may be a terminal device or network device with a Wireless Fidelity (WiFi) chip. Optionally, the site device may support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11bn, 802.11bf, and 802.11a, as well as support the next generation 802.11 protocol, but is not limited thereto.

[0121] Optionally, in an embodiment of the present disclosure, the AP and STA may be devices supporting multiple connections, for example, they may be represented as a multi-connection access point device (AP MLD) and a multi-connection site device (Non-Access Point Multi-Link Device, Non-AP MLD), respectively; the AP MLD may represent an access point supporting multi-connection communication functions, and the non-AP MLD may represent a site supporting multi-connection communication functions.

[0122] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0123] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0124] The various embodiments of the present disclosure can be applied to wireless local area networks (WLANs), such as those using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component of a WLAN. A BSS network consists of station devices with some association within a specific coverage area. One scenario of association is that stations communicate directly with each other in an ad hoc network, which is called an Independent Basic Service Set (IBSS). Another more common scenario is that in a BSS network, there is only one central station dedicated to managing the BSS, called an access point, and all other STAs in the network are associated with it. Other stations in the BSS network that are not the central station are called terminals, also called non-AP STAs. Terminals and non-AP STAs are collectively referred to as STAs. When describing STAs, there is no need to distinguish between APs and non-AP STAs. In the same BSS network, due to distance, transmission power, and other factors, a STA cannot detect other STAs that are farther away from it, and the two STAs are each other's hidden nodes.

[0125] FIG2 is one of the interactive schematic diagrams of the communication method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0126] In step 201 , a first AP 101 determines a first radio frame; wherein the first radio frame identifies a multi-AP coordination strategy supported by the first AP, and the multi-AP coordination strategy includes parameters for multi-AP coordinated transmission.

[0127] With the increasing frequency bands supported by Wi-Fi devices, the trend toward higher frequencies, and the diversification of communication service demands, WLAN device deployments are becoming increasingly dense. This increasing density of APs leads to increased inter-cell interference and increases the risk of access conflicts. To further improve user service quality and overall network performance, while pursuing improvements in communication rates, latency, and reliability within a single BSS, it is necessary to further enhance the M-AP coordination mechanism.

[0128] In an embodiment of the present disclosure, a first AP 101 determines a first radio frame, wherein the first radio frame identifies a multi-AP coordination strategy supported by the first AP, wherein the multi-AP coordination strategy includes parameters for multi-AP coordinated transmission. Optionally, the first AP 101 may be an AP with coordination capability, and the first AP 101 coordinates its neighboring APs (neighboring APs supporting M-AP coordination, illustrated by the second AP 102 in the embodiment of the present disclosure) through a M-AP coordination operation (MAP Coordination Operation, M-APCO), thereby implementing a coordinated transmission mode such as time-frequency resource sharing, spatial multiplexing, or joint transmission.

[0129] The parameters of multi-AP coordinated transmission, such as the coordination strategy type, coordinated transmission start time, transmission mode, etc. of the multi-AP coordinated transmission (scheduling), are used by one or more second APs 102 to determine whether to establish the multi-AP coordinated transmission with the first AP based on the information; or, when the multi-AP coordination strategy includes multiple strategies, the second AP 102 selects a target multi-AP coordination strategy based on its own information and joins it. In this way, the negotiation and establishment of multi-AP coordinated transmission between multiple APs is achieved by sending the first wireless frame, so as to establish efficient coordinated transmission; this helps to avoid problems such as low transmission efficiency and transmission interference in multi-AP coordination, which may occur due to low-latency service transmission within the BSS or interference from other wireless technologies, resulting in the AP being unable to communicate within the multi-AP coordination request transmission SP.

[0130] For example, as shown in Figure 3, when a first AP receives a multi-AP coordinated transmission request from a neighboring AP, the service period (SP) of the restricted target wake time (R-TWT) established by the first AP and its associated STAs overlaps with the SP of the multi-AP coordinated transmission requested by the neighboring AP (the second AP). As shown in MAP Coordination11 in Figure 3, due to the simultaneous transmission of BSS1 and BSS2, the first AP cannot communicate within the SP of the multi-AP coordinated transmission of the second AP, resulting in a certain delay. However, by negotiating a multi-AP coordination strategy, SP overlap can be avoided, thus preventing mutual interference.

[0131] The first radio frame may be a newly defined radio frame or a defined action frame.

[0132] Step 202 : The first AP 101 sends the first wireless frame to the second AP 102 .

[0133] The first AP 101 sends the first radio frame to the second AP 102 , and implements collaborative transmission modes such as time-frequency resource sharing, spatial multiplexing, or joint transmission through a collaborative transmission mode.

[0134] In the embodiment of the present disclosure, the first AP101 and the second AP102 negotiate a multi-AP transmission strategy and establish AP coordinated transmission to avoid problems such as low transmission efficiency and transmission interference in multi-AP coordination caused by the AP being unable to communicate within the multi-AP coordination request transmission SP due to low-latency service transmission in the BSS or interference from other wireless technologies. This further improves the efficiency and accuracy of multi-AP coordination establishment and improves the multi-AP coordinated transmission mechanism.

[0135] Step 203: The second AP 102 receives the first wireless frame.

[0136] The second AP 102 receives the first radio frame, and establishes multi-AP coordinated transmission with the first AP according to the multi-AP coordination strategy supported by the first AP included in the first radio frame.

[0137] In some embodiments, as shown in FIG2 , the first radio frame includes a multi-AP coordination element (MAP Coordination element);

[0138] The MAP Coordination element includes a multi-AP coordination parameter information list field (MAP Coordination Parameter Info List field);

[0139] Among them, the MAP Coordination Parameter Info List field includes one or more multi-AP coordination strategy subfields MAP Coordination Strategy subfield; each of the MAP Coordination Strategy subfields corresponds to one of the multi-AP coordination strategies, and different multi-AP coordination strategies may correspond to different transmission types, transmission start times, and the like.

[0140] In some embodiments, as shown in FIG2 , the MAP Coordination Strategy subfield includes at least one of the following:

[0141] The first identification field Subelement ID identifies the type of the multi-AP coordination strategy; for example, each transmission type uniquely corresponds to an ID.

[0142] The first identifier, for example, Immediate, identifies whether the multi-AP coordinated transmission starts after a frame interval IFS after the multi-AP coordination is successfully established. For example, if Immediate is set to 1, the identifier starts immediately after a frame interval IFS after the multi-AP coordination is successfully established; if Immediate is set to 0, the identifier does not start immediately after a frame interval IFS after the multi-AP coordination is successfully established. For example, after the multi-AP coordination is successfully established, if the first identifier in the first radio frame is set to 1, the multi-AP coordinated transmission starts after the multi-AP coordination is successfully established; if the first identifier in the first radio frame is set to 0, the multi-AP coordinated transmission starts after the multi-AP coordination is successfully established after the first identification information identifies the time.

[0143] The first identification information, for example, Strategy Delay, indicates that after the multi-AP coordination is established, the multi-AP coordinated transmission is started after the delay time identified by the first identification information is delayed; optionally, the first identification information may exist when Immediate is set to 0; the first identification information may also exist independently of Immediate.

[0144] The second identifier identifies whether the multi-AP coordinated transmission successfully established between the first AP and the second AP is a trigger-enabled multi-AP coordinated transmission. For example, the second identifier is set to 1, indicating that the multi-AP coordinated transmission is trigger-enabled; Immediate is set to 0, indicating that it is not triggered.

[0145] In some embodiments, as shown in FIG2 , a first information field and a second information field may be added to the MAP Coordination Strategy subfield, and the first identifier is carried in the first information field of the MAP Coordination Strategy subfield;

[0146] The first identification information is carried in the second information field of the MAP Coordination Strategy subfield;

[0147] The second identifier is carried in the first information field of the MAP Coordination Strategy subfield.

[0148] In some embodiments, the first wireless frame is an action frame (Action), wherein the dialogue token Dialog Token field in the action field of the first wireless frame is set to the same value as the Dialog Token field in the multi-AP coordination establishment request received by the first AP before sending the first wireless frame, identifying the first wireless frame as a response to the multi-AP coordination establishment request; wherein the dialogue token subfield identifies this session to distinguish it from other sessions.

[0149] In some embodiments, the sending of the first radio frame includes:

[0150] The first AP determines the multi-AP coordination type supported by the second AP, and sends a first wireless frame to the second AP;

[0151] The Dialog Token field value in the first radio frame is used to identify this session.

[0152] That is, the first AP knows that the second AP supports a certain type of multi-AP coordination (the first AP can determine the multi-AP coordination strategy supported by the second AP through the information carried in the Beacon frame broadcast by the second AP). The first AP can also actively send a first radio frame to the second AP when it does not receive a multi-AP coordination request from the second AP. The value of the Dialog Token field in the first radio frame is used to identify this session.

[0153] Step 204, the second AP102 sends a second wireless frame; wherein, the second wireless frame indicates that the second AP confirms the establishment of the multi-AP coordinated transmission; wherein, the second wireless frame is an Action frame, and the Dialog Token field in the Action field of the second wireless frame is set to the same value as the Dialog Token field in the first wireless frame, indicating confirmation of the first wireless frame.

[0154] After receiving the first wireless frame, the second AP sends a second wireless frame to the first AP, where the second wireless frame is used to confirm the establishment of the multi-AP coordinated transmission. Optionally, the second wireless frame may also be an Action frame, where the Dialog Token field in the Action field of the second wireless frame is set to the same value as the Dialog Token field in the first wireless frame, indicating confirmation of the first wireless frame.

[0155] Step 205 : The first AP 101 receives a second wireless frame sent by the second AP 102 .

[0156] Step 206: The first AP receives the second wireless frame and sends an ACK to the second AP to confirm receipt of the second wireless frame.

[0157] Step 207: Multi-AP coordination is established successfully.

[0158] After the first AP sends the ACK, it is considered that the multi-AP coordination is successfully established.
