Description
Technical Field
The present invention relates to the field of wireless communications, and in particular, to a method, a terminal, and a medium for searching for a peer terminal in tunnel direct link establishment.
Background
In the 802.11 system, an access device (AP STA) and a terminal (Non-AP STA) are internally deployed with a MAC layer and a PHY layer, wherein main functions of the MAC layer include channel management, connection management, quality of service management, power control, time synchronization, and the like, and 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 called a MAC layer management unit MLME (MAC sublayer management entity) and a physical layer management unit PLME (PHY sublayer management entity), respectively. These units provide low-level management service interfaces through which low-level management functions can be invoked.
In order to provide proper MAC operation, each STA (including Non-AP STA and AP STA) has a high-level management unit therein, such as SME (station management entity, device management unit), which means a high-level management unit above the MAC layer, is a layer-independent unit, which is located in a separate management plane.
Action of SME: typically, the unit is responsible for functions such as collecting layer-related states from various layer management units (MLME and PLME), and similarly, it will also set layer-specific parameter values. SMEs typically perform such functions on behalf of general system management entities. Fig. 1 depicts the relationship between management units.
802.11be networks, also known as Extremely High Throughput (EHT) networks, enhance functionality through a range of system characteristics and mechanisms to achieve extremely high throughput. As the use of Wireless Local Area Networks (WLANs) continues to grow, it is increasingly important to provide wireless data services in many environments, such as homes, businesses, and hotspots. In particular, video traffic will continue to be the dominant traffic type in many WLAN deployments. The throughput requirements of these applications are evolving due to the advent of 4k and 8k video (20 Gbps uncompressed rate). New high throughput, low latency applications such as virtual or augmented reality, gaming, remote offices, and cloud computing will proliferate (e.g., latency for real-time gaming is less than 5 milliseconds).
In view of the high throughput and stringent real-time delay requirements of these applications, users desire to support their applications over a WLAN with higher throughput, higher reliability, less delay and jitter, and higher power efficiency. Users desire improved integration with Time Sensitive Networks (TSNs) to support applications on heterogeneous ethernet and wireless LANs. The 802.11be network aims to ensure the competitiveness of WLAN by further improving the overall throughput and reducing the delay while ensuring backward compatibility and coexistence with legacy technology standards. 802.11 compatible devices operating in the 2.4GHz,5GHz and 6GHz frequency bands.
