Abstract
This disclosure provides methods, devices and systems for scheduling delivery of buffered multicast data to wireless stations (STAs) associated with an access point (AP). In some implementations, a STA transmits, to the AP, a request frame including a multicast address of a multicast group. The AP transmits, to the STA, a Group Identification (ID) assigned to the multicast group. The AP transmits a beacon frame including a wake-up schedule indicating times at which one or more STAs belonging to the multicast group are scheduled to receive buffered multicast data from the AP. STAs that belong to the multicast group wake up at one of the indicated times for a Target Wake Time (TWT) Service Period (SP). STAs that do not belong to the multicast group remain in power save mode during the TWT SP. The AP transmits the buffered multicast data at the indicated time during the TWT SP.
