Background

The 802.11be system, also called an Extra High Throughput (EHT) system, enhances functionality through a series of system features and a variety of mechanisms to achieve extra 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. The 802.11be system aims to ensure the competitiveness of WLAN 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.

In some embodiments, non-AP MLD1 uses STR operation on link1 and link2 if vi1+ vi2 ≧ v1, and vi1+ vi2 ≧ v 2; if vi1+ vi2 < v1, or vi1+ vi2 < v2, then non-AP MLD1 uses the NSTR operation on link1 and link 2. Where v1 is the transmission rate supported by the non-interference link1, v2 is the transmission rate supported by the non-interference link2, and v1 and v2 may be obtained in a broadcast message of the AP MLD1, or obtained in a connection response message sent from the AP MLD1 when connecting.

It should be noted that other relationships between vi1 and vi2 and v1 and v2 may also be used to select the corresponding operation modes, for example, a weight value is set according to the maximum transmission rate supported by the link, a weighted manner is used to calculate vi1 and vi2, and (w 1+ vi1+ w2 + vi 2) is used to compare with v1 and v2, where w1= link1 supported maximum rate/(link 1 supported maximum rate + link2 supported maximum rate), and w2= link2 supported maximum rate/(link 1 supported maximum rate + link2 supported maximum rate). Or when vi1 and vi2 are both greater than a certain preset threshold value, or when vi1 and vi2 are respectively greater than different preset threshold values, non-AP MLD1 uses STR operation on link1 and link2; otherwise, non-AP MLD1 uses the NSTR operation on link1 and link 2.

After reading the channel switching information, the non-AP MLD1 executes the operation of the step 201-202, and if the non-AP MLD1 reads the channel switching information from the broadcast message sent by the AP1, the non-AP MLD1 executes the operation of the step 201-202 according to the broadcast message sent by the AP 1; if the non-AP MLD1 reads the channel switching information from the broadcast message sent by the AP2 first, the operations of steps 201 to 202 are executed according to the broadcast message sent by the AP 2. Transmitting an NSTR start notification message to the AP MLD1 if an operation of the non-AP MLD1 is changed from the STR operation to the NSTR operation due to the change of the channel, transmitting an STR start notification message to the AP MLD1 if the operation of the non-AP MLD1 is changed from the NSTR operation to the STR operation due to the change of the channel, otherwise, the non-AP MLD1 keeps the current operation unchanged.
