Abstract

Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive sensor information from a sensor associated with the user equipment, wherein the user equipment is in a deep sleep mode when the sensor information is received. The user equipment may deactivate the deep sleep mode, based at least in part on receiving the sensor information, to permit the user equipment to transmit or decode a network communication.

First claim

What is claimed is:

1. A method of wireless communication for a wireless communication device, comprising:
entering an idle mode for a first time period indicated by a power saving mode (PSM) timer;
entering, after expiration of the PSM timer, a deep sleep mode for a second time period indicated by a different timer;
receiving sensor information from a sensor associated with the wireless communication device,
wherein the wireless communication device is in the deep sleep mode when the sensor information is received; and

deactivating the deep sleep mode, based at least in part on receiving the sensor information, to permit the wireless communication device to transmit or decode a network communication,
wherein the deep sleep mode is associated with an extended paging cycle.

2. The method of claim 1 , wherein the deep sleep mode is configured according to a hyper system frame number (H-SFN) cycle of the wireless communication device.

3. The method of claim 2 , wherein the H-SFN cycle is configured according to an extended discontinuous reception (E-DRX) cycle of the wireless communication device.

4. The method of claim 1 , wherein the deep sleep mode comprises a power saving mode of the wireless communication device.

5. The method of claim 1 , wherein the different timer is a periodic tracking area update timer.

6. The method of claim 1 , further comprising:
resetting the different timer based at least in part on reporting to a network.

7. The method of claim 1 , wherein deactivating the deep sleep mode comprises switching the wireless communication device to a light sleep mode,
wherein the light sleep mode includes a discontinuous reception (DRX) cycle corresponding to a Radio Resource Control (RRC) idle mode of the wireless communication device.

8. The method of claim 1 , further comprising:
resuming the deep sleep mode after the network communication is transmitted or received by the wireless communication device.

9. The method of claim 8 , wherein resuming the deep sleep mode comprises:
resuming the deep sleep mode based at least in part on completing an action associated with or identified by the network communication.

10. The method of claim 1 , wherein the network communication is received in a next paging occasion after the wireless communication device deactivates the deep sleep mode.

11. The method of claim 1 , wherein the wireless communication device includes a machine-type communication (MTC) device, an Internet of Things (IoT) device, a category M1 wireless communication device, a category narrow band IoT (NB-IoT) device, or a machine-to-machine (M2M) device.

12. The method of claim 1 , wherein the wireless communication device includes the sensor.

13. The method of claim 1 , wherein the sensor is configured to detect a particular stimulus and the wireless communication device is configured to deactivate the deep sleep mode based at least in part on the sensor detecting the particular stimulus.

14. The method of claim 1 , wherein the deep sleep mode is deactivated based at least in part on a determination that the sensor information satisfies a threshold.

15. A device, comprising:
a memory; and
one or more processors operatively coupled to the memory, the one or more processors being configured to:
enter an idle mode for a first time period indicated by a power saving mode (PSM) timer;
enter, after expiration of the PSM timer, a deep sleep mode for a second time period indicated by a different timer;
receive sensor information from a sensor associated with the device,
wherein the device in the deep sleep mode when the sensor information is received; and

deactivate the deep sleep mode, based at least in part on receiving the sensor information, to permit the device to transmit or decode a network communication,
wherein the deep sleep mode is associated with an extended paging cycle.

16. The device of claim 15 , wherein the deep sleep mode is configured according to a hyper system frame number (H-SFN) cycle of the device.

17. The device of claim 16 , wherein the H-SFN cycle is configured according to an extended discontinuous reception (E-DRX) cycle of the device.

18. The device of claim 15 , wherein the deep sleep mode comprises a power saving mode of the device.

19. The device of claim 15 , wherein the different timer is a periodic tracking area update timer.

20. The device of claim 15 , wherein the one or more processors, when deactivating the deep sleep mode, are to switch the device to a light sleep mode,
wherein the light sleep mode includes a discontinuous reception (DRX) cycle corresponding to a Radio Resource Control (RRC) idle mode of the device.

21. A non-transitory computer-readable medium storing one or more instructions for wireless communication,
the one or more instructions, when executed by one or more processors of a wireless communication device, causing the one or more processors to:
enter an idle mode for a first time period indicated by a power saving mode (PSM) timer;
enter, after expiration of the PSM timer, a deep sleep mode for a second time period indicated by a different timer;
receive sensor information from a sensor associated with the wireless communication device,
wherein the wireless communication device is in the deep sleep mode when the sensor information is received; and

deactivate the deep sleep mode, based at least in part on receiving the sensor information, to permit the wireless communication device to transmit or decode a network communication,
wherein the deep sleep mode is associated with an extended paging cycle.

22. The non-transitory computer-readable medium of claim 21 , wherein the deep sleep mode is configured according to a hyper system frame number (H-SFN) cycle of the wireless communication device.

23. The non-transitory computer-readable medium of claim 22 , wherein the H-SFN cycle is configured according to an extended discontinuous reception (E-DRX) cycle of the wireless communication device.

24. The non-transitory computer-readable medium of claim 21 , wherein the deep sleep mode comprises a power saving mode of the wireless communication device.

25. The non-transitory computer-readable medium of claim 21 , wherein the deep sleep mode is deactivated based at least in part on a determination that the sensor information satisfies a threshold.

26. An apparatus for wireless communication, comprising:
means for entering an idle mode for a first time period indicated by a power saving mode (PSM) timer;
means for entering, after expiration of the PSM timer, a deep sleep mode for a second time period indicated by a different timer;
means for receiving sensor information from a sensor associated with the apparatus,
wherein the apparatus is in the deep sleep mode when the sensor information is received; and

means for deactivating the deep sleep mode, based at least in part on receiving the sensor information, to permit the apparatus to transmit or decode a network communication,
wherein the deep sleep mode is associated with an extended paging cycle.

27. The apparatus of claim 26 , wherein the deep sleep mode comprises a power saving mode of the apparatus.

28. The apparatus of claim 26 , wherein the deep sleep mode is configured according to a hyper system frame number (H-SFN) cycle of the apparatus.
