Abstract
This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for protecting latency-sensitive communications among multi-link devices (MLDs). An access point (AP) MLD may establish multiple communication links with a non-AP MLD and schedule a restricted target wake time (r-TWT) service period (SP) on one of the links (the 'r-TWT link'). In some aspects, when a transmit opportunity (TXOP) acquired on a non-r-TWT link overlaps the r-TWT SP, the TXOP may be extended to support an exchange of latency-sensitive traffic on the non-r-TWT link. In some other aspects, any TXOPs occurring on non-r-TWT links may be terminated prior to the start of the r-TWT SP so that latency-sensitive traffic can be exchanged on the r-TWT link during the SP. An AP MLD also may schedule SPs on multiple communication links. In some aspects, the AP MLD may transfer a TWT agreement between the communication links.
