Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to ultra low-power paging frames for wake up and discovery. One example apparatus for wireless communications generally includes at least one interface configured to receive via a first radio and a second radio, wherein the at least one interface receives a paging frame from another apparatus via the second radio while the first radio is in a first power state that is lower than a second power state of the second radio; and a processing system configured to take one or more actions based on a command field included in the paging frame.
