1. A method for wireless communication, comprising:
transmitting, by a network node, a link wakeup indication message to a wireless device over a first link of multiple links between the network node and the wireless device, the link wakeup indication message indicating a request to transition at least one link of the multiple links between an active state and a power saving state,
wherein the link wakeup indication message is transmitted to the wireless device via a frame that includes a first field that includes a set of bits that indicate whether to transition the wireless device and another wireless device between the power saving state and the active state,
wherein the frame includes a second field and a third field that respectively indicates whether to wake up the wireless device and the another wireless device,
wherein the set of bits includes a first bit associated with the wireless device and corresponding to the second field, and
wherein the set of bits includes a second bit associated with the another wireless device and corresponding to the third field; and
responsive to the transmitting the link wakeup indication message, obtaining, by the network node, a link wakeup notification message from the wireless device indicating that at least one link of the multiple links has transitioned between the active state and the power saving state.
