Apparatuses, computer readable media, and methods for waking up Internet of Things (IoT) devices in a high-efficiency wireless local-area network are disclosed. The apparatus of a high-efficiency wireless local-area network (HEW) device may include processing circuitry and transceiver circuitry configured to generate a packet for one or more stations comprising one or more sub-channels. Each sub-channel may include a common wake up physical synchronization in a physical layer and a station dedicated wake up preamble in a media access control (MAC) layer. The station dedicated wake up preamble may include a wake-up identifier for a corresponding station of the one or more stations. The processing circuitry and transceiver circuitry may be further configured to transmit the packet to the one or more stations in accordance with orthogonal frequency division multiple access (OFDMA).
