Description

Method, equipment and storage medium for establishing access point in wireless local area network

Technical Field

The present application relates to the field of wireless communications, and in particular, to a method, an apparatus, and a storage medium for establishing an access point in a wireless local area network.

Background

In the 802.11 system, an access device (AP STA) and a terminal (Non-AP STA) are both internally deployed with a MAC layer and a PHY layer, wherein the main functions of the MAC layer include channel management, connection management, quality of service management, power control, time synchronization, and the like, and the main functions of the PHY layer include modulation, coding, transmission, and the like.

Both the MAC layer and the PHY layer conceptually include management units referred to as a MAC layer management unit MLME (MAC layer management entity) and a physical layer management unit PLME (PHY layer management entity), respectively. These elements provide low-level management service interfaces through which low-level management functions can be invoked.

In order to provide correct MAC operation, each STA (including Non-AP STA and AP STA) has a higher management element, such as SME (device management element), which represents a higher management element above the MAC layer, and is a layer-independent element, which is located in a separate management plane.

The function of SME: typically, this unit is responsible for functions such as collecting layer-related state from various layer management units (MLME and PLME), which similarly also set layer-specific parameter values. SMEs typically perform such functions on behalf of a general system management entity.

802.11be networks, also known as Extreme High Throughput (EHT) networks, are enhanced by a range of system features and a variety of mechanisms to achieve very High Throughput. As the use of Wireless Local Area Networks (WLANs) continues to grow, it becomes increasingly important to provide wireless data services in many environments, such as homes, businesses, and hot spots. In particular, video traffic will continue to be the dominant type of traffic in many WLAN deployments. With the advent of 4k and 8k video (uncompressed rates of 20 Gbps), the throughput requirements for these applications are constantly evolving. New high throughput, low latency applications such as virtual reality or augmented reality, gaming, remote offices, and cloud computing will proliferate (e.g., latency for real-time gaming below 5 milliseconds).

In view of the high throughput and stringent real-time latency requirements of these applications, users expect higher throughput, higher reliability, less latency and jitter, and higher power efficiency when supporting their applications over a WLAN. Users desire improved integration with Time Sensitive Networks (TSNs) to support applications on heterogeneous ethernet and wireless LANs. 802.11be networks aim to ensure the competitiveness of WLANs by further increasing overall throughput and reducing latency, while ensuring backward compatibility and coexistence with legacy technology standards. 802.11 compatible devices operating in the 2.4GHz,5GHz and 6GHz bands.

a higher layer management unit, configured to send an MLME-start request primitive to a lower layer management unit, and request the lower layer management unit to establish the BSS, where the MLME-start request primitive includes parameters BSSType, SSID, beaconPeriod, CF parameter set, PHY parameter set, navcdelay, and OperationalRateSet, where the BSSType is used to indicate a type of a basic service set, the SSID is used to indicate a broadcast identifier of the created BSS, the BeaconPeriod is used to indicate a period of transmission of a Beacon broadcast message, the CF parameter set is used to indicate a parameter for scheduled transmission, the PHY parameter set is used to indicate a physical layer parameter, the NAVSyncDelay is used to indicate a delay time allowed for transmission from a sleep state to an awake state, and the OperationalRateSet is used to indicate a data rate that the BSS can support; if the local parameter dot11EHT topntionImplemented indicates that the equipment supports the EHT system capability or indicates that the equipment supports and enables the EHT system capability, the MLME-START request primitive also comprises parameters EHT capabilities and EHT operation, the EHT capabilities are used for indicating the EHT system capability parameters of the equipment, and the EHT operation is used for indicating the EHT system operation parameters of the equipment; when the local parameter dot11multilink operation executed indicates that the equipment supports the multilink operation capability or indicates that the equipment supports the multilink operation capability and starts the operation, the MLME-start. The ML Elements comprise parameters MLD common info and STA info, wherein the MLD common info is used for indicating the multilink common parameters of the equipment, the STA info i is used for indicating the proprietary parameters of a single logic AP in the equipment, i is more than or equal to 1 and less than or equal to n, and n is determined by the number of the logic APs actually operated in the equipment; the STA info i comprises parameters Link ID, STA Capability and STA operation, wherein the Link ID is used for indicating an identifier of a Link operated by the logic AP, the STA Capability is used for indicating a Capability parameter special for the logic AP, and the STA operation is used for indicating an operation parameter special for the logic AP;

17. An electronic device, comprising a processor and a memory, wherein at least one program code is stored in the memory, and wherein the at least one program code is loaded into and executed by the processor to implement the method for establishing an access point for a wireless local area network according to any of claims 1-15.

18. A storage medium having stored therein at least one program code, the at least one program code loaded into and executed by a processor, to implement the method for establishing an access point for a wireless local area network according to any of claims 1-15.
