Abstract
Methods and apparatuses are described herein for chained and delayed wake-up. For example, a station (STA) may determine, at the formation of a group of STAs, a common service period for the group. The STA may determine a deferral time for a first STA of the group. The deferral time may indicate when the first STA wakes up to receive a wake-up packet. The STA may receive, from an access point (AP), during a service period in which the STA acts as a head node for communication with the AP, a wake-up packet addressed to the first STA. The STA may transmit, based on a determination that the deferral time associated with the wake-up packet addressed to the first STA ends after the service period in which the STA acts as a head node, a wake-up command that includes the wake-up packet addressed to the first STA.
