Abstract

Some demonstrative embodiments include apparatuses, devices, systems and methods of communicating a wakeup packet. For example, an apparatus may include circuitry configured to cause a wireless device to generate a frame comprising a Low-Power Wakeup-Receiver (LP-WUR) capability indication to indicate a capability of the wireless device to process communication of a wakeup packet; and to transmit the frame.

First claim

What is claimed is:

1 . An apparatus comprising circuitry configured to cause a wireless device to:
generate a frame comprising a Low-Power Wakeup-Receiver (LP-WUR) capability indication to indicate a capability of the wireless device to process communication of a wakeup packet; and transmit the frame.

2 . The apparatus of claim 1 , wherein the capability indication is to indicate the wireless device is capable of transmitting the wakeup packet.

3 . The apparatus of claim 2 configured to cause the wireless device to operate as a first wireless device to:
process a received frame from a second wireless device, the received frame comprising the LP-WUR capability indication indicating said second wireless device is capable of receiving wakeup packets; and
transmit to said second wireless device the wakeup packet to wakeup said second wireless device.

4 . The apparatus of claim 1 , wherein the capability indication is to indicate the wireless device is capable of processing a received wakeup packet.

5 . The apparatus of claim 4 configured to cause the wireless device to operate as a first wireless device to:
process a received frame from a second wireless device, the received frame comprising the LP-WUR capability indication indicating said second wireless device is capable of transmitting wakeup packets;
process reception of the wakeup packet from said second wireless device; and
wakeup a radio of said first wireless device.

6 . The apparatus of claim 1 configured to cause the wireless device to operate as a first wireless device to:
transmit a beacon frame comprising the LP-WUR capability indication indicating said first wireless device is capable of transmitting wakeup packets;
process an association request frame received from a second wireless device, the association request frame comprising the LP-WUR capability indication indicating said second wireless device is capable of receiving wakeup packets;
transmit to the second wireless device an association response frame comprising the LP-WUR capability indication indicating said first wireless device is capable of transmitting wakeup packets; and
transmit to said second wireless device the wakeup packet to wakeup said second wireless device.

7 . The apparatus of claim 1 configured to cause the wireless device to operate as a first wireless device to:
process a beacon frame received from a second wireless device, the beacon frame comprising the LP-WUR capability indication indicating said second wireless device is capable of transmitting wakeup packets;
transmit an association request frame to the second wireless device, the association request frame comprising the LP-WUR capability indication indicating said first wireless device is capable of receiving wakeup packets;
process an association response frame received from the second wireless device, the association response frame comprising the LP-WUR capability indication indicating said second wireless device is capable of transmitting wakeup packets;
process reception of the wakeup packet from the second wireless device; and
wakeup a radio of said first wireless device.

8 . The apparatus of claim 1 configured to cause the wireless device to operate as a first wireless device to:
transmit a probe request frame comprising the LP-WUR capability indication indicating said first wireless device is capable of receiving wakeup packets;
process a probe response frame received from a second wireless device, the probe response frame comprising the LP-WUR capability indication indicating said second wireless device is capable of transmitting wakeup packets;
process reception of the wakeup packet from said second wireless device; and
wakeup a radio of said first wireless device.

9 . The apparatus of claim 1 configured to cause the wireless device to operate as a first wireless device to:
process a probe request frame received from a second wireless device, the probe request frame comprising the LP-WUR capability indication indicating said second wireless device is capable of receiving wakeup packets;
transmit a probe response frame to the second wireless device, the probe response frame comprising the LP-WUR capability indication indicating said first wireless device is capable of transmitting wakeup packets; and
transmit the wakeup packet to wakeup the second wireless device.

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

11 . 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 wireless device, the operations comprising:
generating a frame comprising a Low-Power Wakeup-Receiver (LP-WUR) capability indication to indicate a capability of the wireless device to process communication of a wakeup packet; and transmitting the frame.

12 . The product of claim 11 , wherein the capability indication is to indicate that the wireless device is not capable of transmitting or receiving wakeup packets, that the wireless device is capable of transmitting wakeup packets, that the wireless device is capable of receiving wakeup packets, or that the wireless device is capable of both transmitting and receiving wakeup packets.

13 . An apparatus comprising circuitry configured to cause a wireless device to:
transmit a Low-Power Wakeup-Receiver (LP-WUR) Power Save (PS) frame to indicate an LP-WUR mode in which a radio of the wireless device is to be at a power-save mode; switch to the LP-WUR mode; and upon receipt of a wakeup packet at a LP-WUR of the wireless device, switch the radio to an active mode, and transmit a frame to indicate that said radio is ready to receive data.

14 . The apparatus of claim 13 , wherein the LP-WUR Power Save frame comprises a PS override field comprising a predefined value to indicate whether or not a PS bit in a frame control field of a message is to indicate said wireless device is to be switched to the LP-WUR mode.

15 . The apparatus of claim 14 configured to cause the wireless device to:
transmit the LP-WUR Power Save frame comprising said predefined value;
switch to the LP-WUR mode; and
after switching the radio to the active mode, transmit said message comprising said PS bit indicating said wireless device is to be switched to the LP-WUR mode, and switch said radio to the LP-WUR mode.

16 . The apparatus of claim 13 , wherein the LP-WUR Power Save frame comprises an LP-WUR Channel field to indicate a channel to communicate said wakeup packet.

17 . The apparatus of claim 13 , wherein the LP-WUR Power Save frame comprises an LP-WUR preamble length field to indicate a length of a preamble of said wakeup packet.

18 . The apparatus of claim 13 , wherein the LP-WUR Power Save frame comprises an LP-WUR Control field to indicate said wireless device is to be switched to the LP-WUR mode.

19 . The apparatus of claim 13 , wherein the LP-WUR Power Save frame comprises an Access Category (AC) field comprising a first value or a second value, the first value to indicate a first latency to transmit the wakeup packet when data of at least one first access category is pending for said wireless device, the second value to indicate a second latency to transmit the wakeup packet when data of at least one second access category is pending for said wireless device, said second latency is shorter than s
