[0126] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0127] As shown in FIG1 , a communication system 100 includes a first access point (AP) device 101 and a second AP 102 .

[0128] In some embodiments, the first AP 101 and the second AP 102 can be access points for mobile terminals to access a wired network. The AP acts as a bridge between a wired network and a wireless network. Its primary function is to connect various wireless network clients together and then connect the wireless network to the Ethernet. Specifically, the first AP 101 and the second AP 102 can be terminal devices or network devices equipped with wireless fidelity chips. Optionally, the first AP 101 and the second AP 102 can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a, as well as support the next generation 802.11 protocol, but are not limited thereto.

[0129] In some embodiments, the first AP 101 and the second AP 102 can communicate with each other or with their respective associated stations (STAs). The STA can be a device including a wireless communication chip supporting WiFi communication capabilities, a wireless sensor, or a wireless communication terminal. Optionally, the wireless communication terminal can be, for example, at least one of a mobile phone, a wearable device, an IoT device supporting WiFi communication capabilities, a car with WiFi communication capabilities, a smart car, a tablet computer, a computer with wireless transceiver capabilities, 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 smart grids, a wireless terminal device used in transportation safety, a wireless terminal device used in smart cities, and a wireless terminal device used in smart homes, but is not limited thereto.

[0130] Specifically, a STA can be a terminal device or network device with a Wireless Fidelity (WiFi) chip. Optionally, the STA can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a, as well as the next generation 802.11 protocol, but is not limited thereto.

[0131] Optionally, in an embodiment of the present disclosure, the AP and STA may be devices supporting multiple connections, for example, they may be respectively represented as an access point device supporting multiple connections (Access Point Multi-Link Device, AP MLD) and a site device supporting multiple connections (Non-Access Point Multi-Link Device, Non-AP MLD); AP MLD may represent an access point supporting multiple connection communication functions, and non-AP MLD may represent a site supporting multiple connection communication functions.

[0132] 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.

[0133] 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.

[0134] The various embodiments of the present disclosure can be applied to wireless local area networks (WLANs), such as IEEE 802.11 system standards, such as 802.11a / b / g, 802.11n, 802.11ac, 802.11ax, or their successors, such as 802.11be, also known as Wi-Fi 7 or the extremely high throughput (EHT) standard, or even later generations. Alternatively, the various embodiments of the present disclosure can also be applied to wireless local area network systems such as Internet of Things (IoT) networks or Vehicle to X (V2X) networks. Of course, the embodiments of the present disclosure can also be applied to other possible communication systems, such as long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, universal mobile telecommunication system (UMTS), world-wide interoperability for microwave access (WiMAX) communication system, and future fifth generation (5G) communication system.

[0135] The existing 802.11 protocol mainly focuses on how to achieve higher throughput, higher speed, and higher access efficiency within a single Basic Service Set (BSS) or a single AP. There is little research on coordinated transmission between multiple BSSs or multiple APs. With the increase in frequency bands supported by Wi-Fi devices, the trend of higher frequencies, and the diversification of communication services, WLAN equipment deployment is becoming increasingly dense. The increasingly dense APs bring more interference between cells and increase the risk of access conflicts. To further improve user service quality and overall network performance, the next-generation Wi-Fi standard research group UHR is pursuing improvements in communication speed, communication latency, and reliability within a single BSS, while also focusing on coordination between multiple APs. Through collaborative cooperation between multiple APs, communication resources can be more reasonably allocated, ensuring communication quality while improving access efficiency and achieving better network performance.

[0136] In a WLAN, the BSS is a fundamental component. A BSS network consists of associated devices within a specific coverage area. One type of association involves STAs communicating directly with each other within an ad hoc network, known as an Independent Basic Service Set (IBSS). A more common scenario involves a BSS network with a single central station, called an AP, dedicated to managing the BSS. The BSS network includes at least one STA associated with the AP.

[0137] The basic concept of multi-AP coordination is that APs with coordination capabilities can coordinate with neighboring APs (supporting multi-AP coordination) through cooperative transmission mode to achieve time-frequency resource sharing, spatial reuse, or joint transmission, thereby reducing inter-cell interference, ensuring user service quality, improving network communication speeds, and reducing latency. On the other hand, multi-AP coordination is based on the AP's own willingness, and not all APs are willing to be coordinated. For example, people do not want their AP to be controlled or coordinated by a neighboring AP.

[0138] Multi-AP coordinated transmission has attracted much attention, but how to discover APs with multi-AP coordination capabilities, how to establish multi-AP coordinated transmission, and how to manage multi-AP coordinated transmission remain unclear. Therefore, a standardized multi-AP coordinated transmission method and process are needed.

[0139] The following will further describe the technical solutions in the embodiments of the present disclosure in a clear and complete manner with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present disclosure and do not constitute all the embodiments. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present disclosure without creative effort shall fall within the scope of protection of the present disclosure.
