Wake up receiver frame

1. A device, the device comprising processing circuitry coupled to storage, the processing circuitry configured to:

cause to send a wake up receiver (WUR) beacon frame on a WUR beacon operating channel to one or more station devices;

determine a first wake-up frame to be sent on a first WUR operating channel, wherein the first WUR operating channel is associated with one or more frequency division multiple access (FDMA) channels used for transmitting one or more wake-up frames to the one or more station devices determine a second wake-up fame to be sent on a second WUR operating channel different from the first WUR operating channel;

set a legacy signal (L-SIG) indication to be the same for the first wake-up frame and the second wake-up frame;

determine to apply a first padding to the first wake-up frame based on the L-SIG indication included in a header of the first wake-up frame;

determine to apply a second padding to the second wake-up frame, wherein the first padding and second padding are used to align ends of the first wake-up frame and the second wake-up frame; and

cause to send the first wake-up frame to a first station device of the one or more station devices.

2. The device of claim 1 , wherein the processing circuitry is further configured to determine to line up padding of the one or more wake-up frames based on an L-SIG length indication.

3. The device of claim 1 , wherein the first WUR operating channel is different from the WUR beacon operating channel based on an indication by the first station device that it is capable of performing a channel switch.

4. The device of claim 1 , wherein the first WUR operating channel is same as the WUR beacon operating channel based on an indication by the first station device that it is not capable of performing a channel switch.

5. The device of claim 1 , wherein a target time of transmitting the WUR beacon frame does not overlap with a duty cycle of the first station device.

6. The device of claim 1 , wherein a first padding is added after the first wake-up frame.

7. The device of claim 6 , wherein a starting point of a transition delay is from an end of the first wake-up frame and before the first padding.

8. The device of claim 1 , further comprising a transceiver configured to transmit and receive wireless signals, wherein the wireless signals are associated the one or more wake-up frames.

9. The device of claim 8 , further comprising an antenna coupled to the transceiver to cause to send the first wake-up frame.

10. A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:

causing to send a wake up receiver (WUR) beacon frame on a WUR beacon operating channel to one or more station devices;

determining a first wake-up frame to be sent on a first WUR operating channel, wherein the first WUR operating channel is associated with one or more frequency division multiple access (FDMA) channels used for transmitting one or more wake-up frames to the one or more station devices;

determining a second wake-up fame to be sent on a second WUR operating channel different from the first WUR operating channel;

setting a legacy signal (L-SIG) indication to be the same for the first wake-up frame and the second wake-up frame;

determining to apply a first padding to t pickup he first wake-up frame based on the L-SIG indication included in a header of the first wake-up frame;

determining to apply a second padding to the second wake-up frame, wherein the first padding and the second padding are used to alignment ends of the first wake-up frame and the second wake-up frame; and

causing to send the first wake-up frame to a first station device of the one or more station devices.

11. The non-transitory computer-readable medium of claim 10 , wherein the operations further comprise determining to line up padding of the one or more wake-up frames based on an L-SIG length indication.

12. The non-transitory computer-readable medium of claim 10 , wherein the first WUR operating channel is different from the WUR beacon operating channel based on an indication by the first station device that it is capable of performing a channel switch.

13. The non-transitory computer-readable medium of claim 10 , wherein the first WUR operating channel is same as the WUR beacon operating channel based on an indication by the first station device that it is not capable of performing a channel switch.

14. The non-transitory computer-readable medium of claim 10 , wherein a target time of transmitting the WUR beacon frame does not overlap with a duty cycle of the first station device.

15. The non-transitory computer-readable medium of claim 10 , wherein a first padding is added after the first wake-up frame.

16. The non-transitory computer-readable medium of claim 15 , wherein a starting point of a transition delay is from an end of the first wake-up frame and before the first padding.

17. A method comprising:

causing, by one or more processors, to send a wake up receiver (WUR) beacon frame on a WUR beacon operating channel to one or more station devices;

determining a first wake-up frame to be sent on a first WUR operating channel, wherein the first WUR operating channel is associated with one or more frequency division multiple access (FDMA) channels used for transmitting one or more wake-up frames to the one or more station devices;

determining a second wake-up fame to be sent on a second WUR operating channel different from the first WUR operating channel;

setting a legacy signal (L-SIG) indication to be the same for the first wake-up frame and the second wake-up frame;

determining to apply a first padding to the first wake-up frame based on a field the L-SIG indication included in a header of the first wake-up frame;

determining to apply a second padding to the second wake-up frame, wherein the first padding and the second padding are used to alignment ends of the first wake-up frame and the second wake-up frame; and

causing to send the first wake-up frame to a first station device of the one or more station devices.
