1. A method performed by a wireless device, comprising:
wirelessly transmitting a wake-up signal to one or more other wireless devices indicating an upcoming downlink data frame transmission;
wirelessly receiving a response frame that is responsive to the wake-up signal from one of the one or more other wireless devices before an estimated full transition delay has elapsed after the wake-up signal was transmitted, wherein the estimated full transition delay is an estimated delay for a main radio to transition from being in a doze state to being in an awake state, wherein the estimated full transition delay includes an estimated delay to activate a radio frequency or baseband component and an estimated delay to load a program for execution for data frame reception, wherein the one of the one or more other wireless devices transmits the response frame via its main radio after activating a radio frequency or baseband component of its main radio but before its main radio has fully transitioned from being in the doze state to being in the awake state; and
wirelessly transmitting, after the estimated full transition delay has elapsed, the data frame that includes data intended for the one or more other wireless device in response to a determination that the response frame has been received.
