Abstract

Some demonstrative embodiments include apparatuses, devices, systems and methods of a wakeup packet response. For example, an apparatus may include circuitry configured to cause a first wireless device to generate a wakeup packet including a wakeup response policy field to indicate a response policy; and to transmit the wakeup packet to a wakeup receiver of a second wireless device over a wakeup Resource Unit (RU) allocation of an Orthogonal Frequency Division Multiple Access (OFDMA) structure.

First claim

What is claimed is:

1 . An apparatus comprising circuitry configured to cause a first wireless device to:
generate a wakeup packet comprising a wakeup response policy field to indicate a response policy; and transmit the wakeup packet to a wakeup receiver of a second wireless device over a wakeup Resource Unit (RU) allocation of an Orthogonal Frequency Division Multiple Access (OFDMA) structure.

2 . The apparatus of claim 1 configured to cause the first wireless device to:
generate said wakeup response policy field comprising a value to indicate an OFDMA packet response policy, and generate said wakeup packet comprising trigger timing information; and
transmit a trigger frame to the second wireless device based on the trigger timing information.

3 . The apparatus of claim 2 configured to cause the first wireless device to generate the wakeup packet comprising a response RU allocation of the OFDMA structure for transmission of a response to said wakeup packet.

4 . The apparatus of claim 3 configured to cause the first wireless device to process reception of said response over the response RU allocation of the OFDMA structure.

5 . The apparatus of claim 1 configured to cause the first wireless device to generate the wakeup response policy field comprising a value to indicate an Orthogonal Frequency Division Multiplexing (OFDM) packet response policy, and to generate the wakeup packet comprising contention timing information to indicate a time for the second wireless device to contend a wireless medium to transmit a response to the wakeup packet.

6 . The apparatus of claim 5 configured to cause the first wireless device to process a received OFDM packet including said response.

7 . The apparatus of claim 1 configured to cause the first wireless device to generate the wakeup response policy field comprising a value to indicate a no response policy.

8 . The apparatus of claim 1 configured to cause the first wireless device to transmit the wakeup packet to a plurality of wireless devices according to the OFDMA structure.

9 . The apparatus of claim 1 configured to cause the first wireless device to process an indication that said second wireless device is at a sleep mode, and to generate said wakeup packet to wakeup said second wireless device.

10 . The apparatus of claim 1 comprising a radio to transmit said wakeup packet.

11 . The apparatus of claim 1 comprising one or more antennas, a processor, and a memory.

12 . A product comprising one or more tangible computer-readable non-transitory storage media comprising computer-executable instructions operable to, when executed by at least one computer processor, enable the at least one computer processor to implement one or more operations at a first wireless device, the operations comprising:
generating a wakeup packet comprising a wakeup response policy field to indicate a response policy; and transmitting the wakeup packet to a wakeup receiver of a second wireless device, over a wakeup Resource Unit (RU) allocation of an Orthogonal Frequency Division Multiple Access (OFDMA) structure.

13 . The product of claim 12 , wherein the operations comprise:
generating said wakeup response policy field comprising a value to indicate an OFDMA packet response policy, and generating said wakeup packet comprising trigger timing information; and transmitting a trigger frame to the second wireless device based on the trigger timing information.

14 . An apparatus comprising circuitry configured to cause a first wireless device to:
process a wakeup packet received from a second wireless device over a wakeup Resource Unit (RU) allocation of an Orthogonal Frequency Division Multiple Access (OFDMA) structure, the wakeup packet comprising a wakeup response policy field to indicate a response policy; selectively transmit a response to the second wireless device according to the response policy; and wakeup a transceiver to communicate data with said second wireless device.

15 . The apparatus of claim 14 configured to cause the first wireless device to transmit the response over a response RU allocation of the OFDMA structure, when the wakeup response policy field comprises a value to indicate an OFDMA packet response policy, and the wakeup packet comprises the response RU allocation of the OFDMA structure.

16 . The apparatus of claim 15 configured to cause the first wireless device to wakeup said transceiver to receive a trigger frame transmission from said second wireless device based on trigger timing information in said wakeup packet, and to transmit the response frame in response to said trigger frame.

17 . The apparatus of claim 14 configured to cause the first wireless device to transmit to the second wireless device an Orthogonal Frequency Division Multiplexing (OFDM) packet including the response, when the wakeup response policy field comprises a value to indicate an OFDM packet response policy.

18 . The apparatus of claim 17 configured to cause the first wireless device to contend for a wireless medium to transmit said response based on contention timing information in the wakeup packet.

19 . The apparatus of claim 18 configured to cause the first wireless device to wakeup said transceiver to contend for said wireless medium based on said contention timing information.

20 . The apparatus of claim 14 configured to cause the first wireless device to select not to transmit said response, when the wakeup response policy field comprises a value to indicate a no response policy.

21 . The apparatus of claim 14 configured to cause the first wireless device to process said wakeup packet, when said transceiver is at a sleep mode.

22 . The apparatus of claim 14 comprising a wakeup receiver to receive said wakeup packet.

23 . The apparatus of claim 14 comprising one or more antennas, a processor, and a memory.

24 . A product comprising one or more tangible computer-readable non-transitory storage media comprising computer-executable instructions operable to, when executed by at least one computer processor, enable the at least one computer processor to implement one or more operations at a first wireless device, the operations comprising:
processing a wakeup packet received from a second wireless device over a wakeup Resource Unit (RU) allocation of an Orthogonal Frequency Division Multiple Access (OFDMA) structure, the wakeup packet comprising a wakeup response policy field to indicate a response policy; selectively transmitting a response to the second wireless device according to the response policy; and waking up a transceiver to communicate data with said second wireless device.

25 . The product of claim 24 , wherein the operations comprise transmitting the response over a response RU allocation of the OFDMA structure, when the wakeup response policy field comprises a value to indicate an OFDMA packet response policy, and the wakeup packet comprises the response RU allocation of the OFDMA structure.
