TRAFFIC INDICATION IN MULTI-LINK OPERATION - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17661218 Titled 'TRAFFIC INDICATION IN MULTI-LINK OPERATION'
Simplified Explanation
This disclosure presents methods, devices, and systems to address issues related to beacon bloat, inefficient spectrum use, and the coupling of multi-link transmission element (MLTE) with a traffic indication map (TIM) element. One approach is to transmit the MLTE separately from the beacon frame, reducing the size of the beacon frame. This allows the beacon frame to indicate to non-AP MLDs to stay awake for data reception. Another approach is for the access point (AP) to transmit multiple MLTEs, eliminating non-AP MLDs and other stations (STAs) without buffered data to reduce bandwidth usage. Additionally, the AP can assign each non-AP MLD a traffic indication bitmap (TIB) to decouple the MLTE from the TIM element.
Original Abstract Submitted
This disclosure provides methods, devices and systems for reducing beacon bloat, inefficient spectrum use, and coupling of multi-link transmission element (MLTE) with a traffic indication map (TIM) element. In certain aspects, an MLTE may be transmitted by an access point (AP) multi-link device (MLD) in a frame separate from the beacon frame to reduce the size of the beacon frame. In such an example, the beacon frame may provide an indication to a non-AP MLD that is should remain awake to receive data. In certain aspects, the AP may transmit multiple MLTEs to reduce the amount of bandwidth used for MLTE transmission by cutting out non-AP MLDs and other stations (STAs) that do not have buffered data. In certain aspects, the AP may assign each non-AP MLD capable of transmission identifier (TID)-to-link mapping (TID2LM) with a per-link traffic indication bitmap (PLTIB) to decouple the MLTE from the TIM element.
