Claim 0:
1. A non-access point (AP) multi-link device (MLD) comprising:
a plurality of stations (STAs) that each comprise a transceiver configured to transmit and receive signals in target wake time (TWT) operation on multi-link operation (MLO) links between the STAs and corresponding APs of an AP MLD, respectively; and
a processor operably coupled to the transceivers, the processor configured to:
negotiate a broadcast TWT schedule over a first link between a first STA and a first AP of the AP MLD, wherein the broadcast TWT schedule is for a shared TWT session including a group of the links;
after the broadcast TWT schedule is successfully negotiated, apply the broadcast TWT schedule to the group of links;
negotiate a restricted TWT schedule with the AP MLD over at least one link of the group of links; and
after the restricted TWT schedule is successfully negotiated, establish the restricted TWT schedule on one or more links of the at least one link, such that the one or more links are members of the restricted TWT schedule.
