Abstract

This disclosure describes systems, methods, and devices related to wake-up frame indication. A device may determine a wake up receiver (WUR) wake-up frame to be sent to a first station device of one or more station devices. The device may determine one or more indications associated with the first station device, wherein the one or more indications indicate to the first station device, one or more actions to be taken by the first station device after waking up a primary connectivity radio (PCR) of the first station device. The device may cause a medium access control (MAC) layer to encode the WUR wake-up frame with the one or more indications associated with the first station device. The device may cause to send the WUR wake-up frame to the first station device using a physical layer (PHY).

First claim

What is claimed is:

1. A device, the device comprising processing circuitry coupled to storage, the processing circuitry configured to:
generate a Wake-up Receiver (WUR) wake-up frame to be sent to a first station device, the WUR wake-up frame comprising:
a WUR group identification (ID) or a check beacon indication, wherein the WUR group ID indicates group addressed bufferable units (BUs) assigned to the first station device, and wherein the check beacon indicates to the first station device to attempt to receive a beacon frame; and
transmit the WUR wake-up frame to the first station device, causing the first station device to proceed with operations similar to receiving a traffic indication map (TIM).

2. The device of claim 1 , wherein the WUR wake-up frame further comprises an ID field that identifies the first station device, and wherein the ID field indicates a presence of one or more individually addressed BUs associated with the first station device.

3. The device of claim 1 , wherein the device is a WUR AP access point, and wherein the first station device is a WUR non-access point (AP) station device.

4. The device of claim 3 , wherein a reception of the WUR wake-up frame by the first station device with an indication of BUs causes the first station device to follow existing operation, associated with power save that the WUR AP and the WUR non-AP station device has agreed to use.

5. The device of claim 1 , wherein transmitting the WUR wake-up frame to the first station device indicates to the first station device to retrieve the group addressed bufferable units.

6. The device of claim 1 , wherein the group ID indicates to the first station device to follow a similar requirement as after receiving a TIM indication with bit 0 of TIM bitmap set to indicate a presence of group addressed bufferable units.

7. The device of claim 1 , wherein the WUR wake-up frame is a broadcast frame sent to a group of station devices, and wherein the first station device is part of the group.

8. The device of claim 1 , wherein the group of station devices comprises station devices that are associated with a particular group identified by the WUR group ID.

9. A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:
generating a Wake-up Receiver (WUR) wake-up frame to be sent to a first station device, the WUR wake-up frame comprising:
a WUR group identification (ID) or a check beacon indication, wherein the WUR group ID indicates group addressed bufferable units (BUs) assigned to the first station device, and wherein the check beacon indicates to the first station device to attempt to receive a beacon frame; and
transmitting the WUR wake-up frame to the first station device, causing the first station device to proceed with operations similar to receiving a traffic indication map (TIM).

10. The non-transitory computer-readable medium of claim 9 , wherein the WUR wake-up frame further comprises an ID field that identifies the first station device, and wherein the ID field indicates a presence of one or more individually addressed BUs associated with the first station device.

11. The non-transitory computer-readable medium of claim 9 , wherein the device is a WUR AP access point, and wherein the first station device is a WUR non-access point (AP) station device.

12. The non-transitory computer-readable medium of claim 9 , wherein a reception of the WUR wake-up frame by the first station device with an indication of BUs causes the first station device to follow existing operation, associated with power save that the WUR AP and the WUR non-AP station device has agreed to use.

13. The non-transitory computer-readable medium of claim 9 , wherein transmitting the WUR wake-up frame to the first station device indicates to the first station device to retrieve the group addressed bufferable units.

14. The non-transitory computer-readable medium of claim 9 , wherein the group ID indicates to the first station device to follow a similar requirement as after receiving a TIM indication with bit 0 of TIM bitmap set to indicate a presence of group addressed bufferable units.

15. The non-transitory computer-readable medium of claim 9 , wherein the WUR wake-up frame is a broadcast frame sent to a group of station devices, and wherein the first station device is part of the group.

16. The non-transitory computer-readable medium of claim 9 , wherein the group of station devices comprises station devices that are associated with a particular group identified by the WUR group ID.

17. A method comprising:
generating, by one or more processors, a Wake-up Receiver (WUR) wake-up frame to be sent to a first station device, the WUR wake-up frame comprising:
a WUR group identification (ID) or a check beacon indication, wherein the WUR group ID indicates group addressed bufferable units (BUs) assigned to the first station device, and wherein the check beacon indicates to the first station device to attempt to receive a beacon frame; and
transmitting the WUR wake-up frame to the first station device, causing the first station device to proceed with operations similar to receiving a traffic indication map (TIM).

18. The method of claim 17 , wherein the WUR wake-up frame further comprises an ID field that identifies the first station device, and wherein the ID field indicates a presence of one or more individually addressed BUs associated with the first station device.

19. The method of claim 17 , wherein the device is a WUR AP access point, and wherein the first station device is a WUR non-access point (AP) station device.

20. The method of claim 19 , wherein a reception of the WUR wake-up frame by the first station device with an indication of BUs causes the first station device to follow existing operation, associated with power save that the WUR AP and the WUR non-AP station device has agreed to use.
