Waking up internet of things devices in a high efficiency wireless local-area network

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors, the instructions to configure the one or more processors to cause a wireless apparatus to:

• generate one or more packets to be transmitted on one or more sub-channels to one or more stations;
• generate a common wake-up physical synchronization field as part of each packet of the one or more packets;
• and
• generate a station dedicated wake-up preamble as part of each packet of the one or more packets corresponding to each station of the one or more stations;
• and
• encode the one or more packets in accordance with orthogonal frequency division multiple access (OFDMA), wherein the one or more packets are to be transmitted on the corresponding one or more sub-channels.

A method performed by a wireless local-area network device, the method comprising:

• generating one or more packets to be transmitted on one or more sub-channels to one or more stations;
• generating a common wake-up physical synchronization field as part of each packet of the one or more packets;
• and
• generating a station dedicated wake-up preamble as part of each packet of the one or more packets corresponding to each station of the one or more stations:
• and
• encoding the one or more packets in accordance with orthogonal frequency division multiple access (OFDMA), wherein the one or more packets are to be transmitted on the corresponding one or more sub-channels.

An wireless apparatus comprising a memory, and processing circuitry including (Physical Layer) PHY circuitry and (Medium Access Control) MAC circuitry, wherein:

• the PHY circuitry is configured to operate in a shallow sleep mode, and to enter a non-shallow sleep mode in response to reception on a sub-channel of a common wake-up physical synchronization field, wherein in shallow sleep mode in shallow sleep mode a portion of the MAC circuitry is asleep;
• and
• the MAC circuitry is configured to operate in a non-shallow sleep mode, wherein in non-shallow sleep mode the wireless apparatus is configured to:
• return to the shallow sleep mode if a wake up identifier in a received station dedicated wake up preamble does not indicate the wireless apparatus, and
• if the wake-up identifier does indicate the wireless apparatus, decode a downlink communication or encode an uplink communication, wherein in the non-shallow sleep mode the portion of the MAC circuitry is awake.
