TUNNELED DIRECT-LINK SETUP CHANNEL SWITCHING WITH NON-SIMULTANEOUS TRANSMIT AND RECEIVE OPERATION - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17842668 Titled 'TUNNELED DIRECT-LINK SETUP CHANNEL SWITCHING WITH NON-SIMULTANEOUS TRANSMIT AND RECEIVE OPERATION'
Simplified Explanation
This abstract describes methods and devices used to avoid violating NSTR (Non-Scheduled Traffic Request) constraints in a wireless local area network. Specifically, it focuses on the issue of TDLS (Tunneled Direct Link Setup) channel switching and link enablement in multi-link operation (MLO).
The methods involve determining when to switch the frequency channel used by a TDLS direct link from one channel to another. This direct link is established between a station (STA) of a non-access point (AP) multi-link device (MLD) and a corresponding peer STA.
To facilitate the channel switch, a TDLS channel switch notification message is generated. This message includes an indication that the TDLS direct link is switching from the first frequency channel to the second frequency channel.
Finally, the TDLS channel switch notification message is transmitted to an AP MLD (to which the non-AP MLD is associated) on an MLO link. MLO links are formed between STAs of the non-AP MLD and APs of the AP MLD.
In summary, this abstract presents a solution for managing TDLS channel switching and link enablement in a wireless network to avoid violating NSTR constraints.
Original Abstract Submitted
Methods and apparatuses for facilitating avoidance of NSTR constraint violation caused by TDLS channel switching and link enablement in multi-link operation (MLO) in a wireless local area network. The methods include determining to switch a frequency channel used by a first tunneled direct link setup (TDLS) direct link from a first frequency channel to a second frequency channel, wherein the TDLS direct link is formed between a station (STA) of a non-access point (AP) multi-link device (MLD) and a corresponding peer STA, generating a TDLS channel switch notification message that includes an indication that the first TDLS direct link is switching from the first to the second frequency channel, and transmitting, to an AP MLD with which the non-AP MLD is associated, on an MLO link, the TDLS channel switch notification message, wherein MLO links are formed between STAs of the non-AP MLD and APs of the AP MLD.
