WIPO Patent Application WO/2022/182146
Kind Code:
A1
Abstract:
Embodiments of the present disclosure provide methods and apparatuses for facilitating broadcast target wake time (TWT) operation in a wireless local area network. The apparatuses include a non-access point (AP) multi-link device (MLD) comprising a transceiver and a processor operably coupled to the transceiver. The processor is configured to perform a multi-link (ML) setup operation with an AP MLD to set up links between the STAs affiliated with the non-AP MLD and corresponding APs affiliated with the AP MLD, negotiate a broadcast TWT agreement over a first link between a first STA and a first AP of the AP MLD, wherein the broadcast TWT agreement is for a shared TWT session including a group of the links, and after the broadcast TWT agreement is successfully negotiated, apply the broadcast TWT agreement to the group of links.
