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:
a memory; and
a processor configured to cause a first wireless device to:
generate a wakeup packet comprising trigger timing information and a wakeup response policy field to indicate a response policy, the wakeup response policy field comprising a value to indicate an Orthogonal Frequency Division Multiple Access (OFDMA) packet response policy, the wakeup packet comprising a response Resource Unit (RU) allocation of an OFDMA structure for transmission of a response to said wakeup packet;
transmit the wakeup packet to a wakeup receiver of a second wireless device over a wakeup RU allocation of the OFDMA structure, the wakeup packet to indicate that a radio of the second wireless device is to be woken up, the OFDMA structure comprising the wakeup RU allocation and a plurality of other RU allocations, the wakeup RU allocation allocated for communication of the wakeup packet, the plurality of other RU allocations allocated for OFDMA communication of one or more data packets;
transmit a trigger frame to the second wireless device based on the trigger timing information; and
process reception of said response over the response RU allocation of the OFDMA structure.

2. The apparatus of claim 1 , wherein the wakeup RU allocation comprises one or more sub-bands at a center of an OFDMA channel, and the plurality of other RU allocations comprises one or more other sub-bands of the OFDMA channel.

3. 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.

4. 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.

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

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

7. An apparatus comprising:
a memory; and
a processor configured to cause a first wireless device to:
generate a wakeup packet comprising a wakeup response policy field to indicate a response policy, the wakeup response policy field comprising a value to indicate an Orthogonal Frequency Division Multiplexing (OFDM) packet response policy, the wakeup packet comprising contention timing information to indicate a time for a second wireless device to contend a wireless medium to transmit a response to the wakeup packet;
transmit the wakeup packet to a wakeup receiver of the second wireless device over a wakeup Resource Unit (RU) allocation of an Orthogonal Frequency Division Multiple Access (OFDMA) structure, the wakeup packet to indicate that a radio of the second wireless device is to be woken up, the OFDMA structure comprising the wakeup RU allocation and a plurality of other RU allocations, the wakeup RU allocation allocated for communication of the wakeup packet, the plurality of other RU allocations allocated for OFDMA communication of one or more data packets; and
process a received OFDM packet including said response.

8. The apparatus of claim 7 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 7 comprising a radio to transmit said wakeup packet.

10. The apparatus of claim 7 , wherein the wakeup RU allocation comprises one or more sub-bands at a center of an OFDMA channel, and the plurality of other RU allocations comprises one or more other sub-bands of the OFDMA channel.

11. The apparatus of claim 7 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.

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 processor, enable the at least one processor to cause a first wireless device to:
generate a wakeup packet comprising trigger timing information and a wakeup response policy field to indicate a response policy, the wakeup response policy field comprising a value to indicate an Orthogonal Frequency Division Multiple Access (OFDMA) packet response policy, the wakeup packet comprising a response Resource Unit (RU) allocation of an OFDMA structure for transmission of a response to said wakeup packet;
transmit the wakeup packet to a wakeup receiver of a second wireless device, over a wakeup RU allocation of the OFDMA structure, the wakeup packet to indicate that a radio of the second wireless device is to be woken up, the OFDMA structure comprising the wakeup RU allocation and a plurality of other RU allocations, the wakeup RU allocation allocated for communication of the wakeup packet, the plurality of other RU allocations allocated for OFDMA communication of one or more data packets;
transmit a trigger frame to the second wireless device based on the trigger timing information; and
process reception of said response over the response RU allocation of the OFDMA structure.

13. The product of claim 12 , wherein the wakeup RU allocation comprises one or more sub-bands at a center of an OFDMA channel, and the plurality of other RU allocations comprises one or more other sub-bands of the OFDMA channel.

14. An apparatus comprising:
a memory; and
a processor configured to cause a first wireless device to:
process at a wakeup receiver of the first wireless device 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, the OFDMA structure comprising the wakeup RU allocation and a plurality of other RU allocations, the wakeup RU allocation allocated for communication of the wakeup packet, the plurality of other RU allocations allocated for OFDMA communication of one or more data packets;
selectively transmit a response to the second wireless device according to the response policy; and
wakeup a transceiver of the first wireless device to communicate data with said second wireless device,
wherein the processor is configured to, when the wakeup response policy field comprises a value to indicate an OFDMA packet response policy, 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, in response to said trigger frame, to transmit the response to the second wireless device over a response RU allocation of the OFDMA structure.

15. The apparatus of claim 14 , wherein the wakeup RU allocation comprises one or more sub-bands at a center of an OFDMA channel, and the plurality of other RU allocations comprises one or more other sub-bands of the OFDMA channel.
