[0113] As shown in FIG1 , a multi-AP coordination system 100 includes a first access point (AP) 101 and a second access point 102 .
[0114] In some embodiments, the first access point device 101 and the second access point device 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 and 802.11a, 802.11bf, 802.11bn, and support the next generation 802.11 protocol, but is not limited to this.
[0115] Optionally, in an embodiment of the present disclosure, the AP and STA (station) may be devices supporting multiple connections, for example, they may be respectively 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); AP MLD may represent an access point supporting multi-connection communication functions, and non-AP MLD may represent a site supporting multi-connection communication functions.
[0116] In some embodiments, the station device includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports Wi-Fi communication. Optionally, the wireless communication terminal includes, but is not limited to, at least one of a mobile phone, a wearable device, an Internet of Things device that supports Wi-Fi communication, a car with WiFi communication, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and a wireless terminal device in a smart home.
[0117] Specifically, the station device can be a terminal device or network device with a Wireless Fidelity (Wi-Fi) chip. Optionally, the relay device 102 and the station device 103 can support multiple 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 support the next generation 802.11 protocol, but are not limited thereto.
[0118] 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.
[0119] 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.
[0120] The various embodiments of the present disclosure can be applied to a wireless local area network (WLAN), such as a local area network that adopts the 802.11 series of protocols. In a WLAN, a basic service set (BSS) is a basic component of a WLAN. A BSS network is composed of station devices with certain associations 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 with a dedicated BSS management function, which is called an access point device, and other stations in the BSS network that are not APs are called terminals, also called non-AP STAs. APs 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, etc., a STA cannot detect other STAs that are farther away from it, and the two are hidden nodes of each other.
[0121] FIG2 is a schematic diagram illustrating an interaction of a multi-AP coordination method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:
[0122] In step 201, the first AP 101 determines a first wireless frame; the first wireless frame is a multiple access point device multiple AP coordination establishment frame (MAP Coordination establishment frame; Multiple AP, MAP); wherein the first wireless frame includes first identification information; the first identification information is used to identify the first wireless frame as a multiple AP coordination establishment request frame or a multiple AP coordination establishment response frame.
[0123] Existing 802.11 protocols primarily focus on improving the throughput, rate, and access efficiency of a single BSS or AP. Research on coordinated transmission between multiple BSSs or APs is limited. With the increasing frequency bands supported by Wi-Fi devices and the trend toward higher frequencies, coupled with the diverse demands of communication services, WLAN device deployments are becoming increasingly dense. Consequently, the increasing density of APs can lead to increased inter-cell interference and increase the risk of access conflicts.
[0124] To further enhance user service quality and overall network performance, UHR requires coordination between multiple access points (APs), while pursuing improvements in communication rates, latency, and reliability within a single BSS. Collaboration among multiple APs allows for more rational allocation of communication resources, ensuring communication quality while improving access efficiency and achieving better network performance. Multi-AP coordination primarily eliminates inter-BSS interference, improves user service quality, and reduces latency by implementing coordination strategies such as time-frequency and frequency-domain resource sharing, spatial multiplexing, or joint transmission among multiple APs. However, establishing multi-AP coordination requires efficient signaling for coordinated transmission between APs.
[0125] To this end, in an embodiment of the present disclosure, the first AP101 determines a first wireless frame, which is a multi-AP coordination establishment frame. The first identification information carried by the first wireless frame identifies the first wireless frame as a multi-AP coordination establishment request frame or a multi-AP coordination establishment response frame. In this way, a multi-AP coordination establishment request or a multi-AP coordination establishment response can be performed through the first wireless frame, thereby realizing interaction between multiple APs through the multi-AP coordination establishment frame and establishing coordination between multiple access point devices.

[0152] The second information field includes at least two bits, and the bits correspond to the coordination type. The second identification information identifies the multi-AP coordination type corresponding to the target bit, and the parameter value of the target bit is set to a third parameter value.
[0153] When the second identification information identifies the multi-AP coordination type corresponding to the preset parameter value, the preset parameter value can correspond to the multi-AP coordination type one by one.

Assuming that the first bit corresponds to C-SR coordination, the second bit corresponds to C-TDMA coordination, the third bit corresponds to C-OFDMA coordination, and the third parameter value is 1, then: if the second bit is set to 1, the second identification information identifies C-TDMA coordination; if all three bits are set to 1, the second identification information identifies a combined coordination method of C-SR coordination, C-TDMA coordination, and C-OFDMA coordination.
