Abstract

Methods, systems, apparatuses, and devices are described for transmitting a measurement report during wireless communications. When, for example, a low-power period (e.g., CDRX OFF period) is scheduled to begin during a time defined by a measurement event timer (TTT timer), a UE may modify the low-power period. The low-power period may be modified based, at least in part on determining the low-power period of the UE will begin during a time defined by a measurement event timer, a duration of the measurement event timer, and a duration of the low-power period. Modifying the low-power period may include delaying the start of the low-power state until after transmission of the MR associated with the measurement event timer or skipping the low-power period altogether. The UE may transmit the MR based, at least in part, on the modification.

Claims (50)

1. A method for wireless communications by a user equipment (UE), comprising:

determining a low-power period of the UE will begin during a time defined by a measurement event timer;

modifying the low-power period based, at least in part, on the determination, a duration of the measurement event timer, and a duration of the low-power period; and

transmitting a measurement report (MR) associated with the measurement event timer based, at least in part, on the modification.

2. The method of claim 1 , wherein modifying the low-power period comprises prioritizing the measurement event timer over the low-power period.

3. The method of claim 1 , wherein the modifying is based, at least in part, on a difference between the duration of the measurement event timer and the duration of the low-power period.

4. The method of claim 1 , wherein the duration of the measurement event timer is shorter than the duration of the low-power period.

5. The method of claim 1 , wherein modifying the low-power period comprises:

delaying start of the low-power period until expiry of the measurement event timer upon determining enough time remains in the low-power period after transmission of the MR for the UE to enter and exit the low-power period.

6. The method of claim 1 , wherein modifying the low-power period comprises:

skipping the low-power period when enough time does not remain in the low-power period after transmission of the MR for the UE to enter and exit the low-power period.

7. The method of claim 1 , wherein the modifying occurs when a mobility parameter of the UE exceeds a threshold.

8. The method of claim 7 , wherein the threshold indicates one of a moderate or high UE mobility scenario.

9. The method of claim 1 , wherein the measurement event timer is a Time to Trigger (TTT) timer.

10. The method of claim 1 , wherein the low-power period is a connected mode discontinuous reception (CRDX) OFF period.

11. An apparatus for wireless communications by a user equipment (UE), comprising:

means for determining a low-power period of the UE will begin during a time defined by a measurement event timer;

means for modifying the low-power period based, at least in part, on the determination, a duration of the measurement event timer, and a duration of the low-power period; and

means for transmitting a measurement report (MR) associated with the measurement event timer based, at least in part, on the modification.

12. The apparatus of claim 11 , wherein the means for modifying the low-power period comprises means for prioritizing the measurement event timer over the low-power period.

13. The apparatus of claim 11 , wherein the means for modifying is based, at least in part, on a difference between the duration of the measurement event timer and the duration of the low-power period.

14. The apparatus of claim 11 , wherein the duration of the measurement event timer is shorter than the duration of the low-power period.

15. The apparatus of claim 11 , wherein the means for modifying the low-power period comprises:

means for delaying start of the low-power period until expiry of the measurement event timer upon determining enough time remains in the low-power period after transmission of the MR for the UE to enter and exit the low-power period.

16. The apparatus of claim 11 , wherein the means for modifying the low-power period comprises:

means for skipping the low-power period when enough time does not remain in the low-power period after transmission of the MR for the UE to enter and exit the low-power period.

17. The apparatus of claim 11 , wherein the means for modifying occurs when a mobility parameter of the UE exceeds a threshold.

18. The apparatus of claim 17 , wherein the threshold indicates one of a moderate or high UE mobility scenario.

19. The apparatus of claim 11 , wherein the measurement event timer is a Time to Trigger (TTT) timer.

20. The apparatus of claim 11 , wherein the low-power period is a connected mode discontinuous reception (CRDX) OFF period.

21. An apparatus for wireless communications by a user equipment (UE), comprising at least one processor, a memory coupled to the at least one processor with instructions stored thereon, and a transmitter, wherein:

the at least one processor is configured to:

determine a low-power period of the UE will begin during a time defined by a measurement event timer; and

modify the low-power period based, at least in part, on the determination, a duration of the measurement event timer, and a duration of the low-power period; and

the transmitter is configured to:

transmit a measurement report (MR) associated with the measurement event timer based, at least in part, on the modification.

22. The apparatus of claim 21 , wherein the at least one processor is configured to modify the low-power period by prioritizing the measurement event timer over the low-power period.

23. The apparatus of claim 21 , wherein the at least one processor is configured to modify based, at least in part, on a difference between the duration of the measurement event timer and the duration of the low-power period.

24. The apparatus of claim 21 , wherein the duration of the measurement event timer is shorter than the duration of the low-power period.

25. The apparatus of claim 21 , wherein the at least one processor is configured to modify the low-power period by delaying start of the low-power period until expiry of the measurement event timer upon determining enough time remains in the low-power period after transmission of the MR for the UE to enter and exit the low-power period.

26. The apparatus of claim 21 , wherein the at least one processor is configured to modify the low-power period by skipping the low-power period when enough time does not remain in the low-power period after transmission of the MR for the UE to enter and exit the low-power period.

27. A non-transitory computer readable medium for wireless communications having instructions stored thereon, the instructions executable by one or more processors for:

determining a low-power period of a user equipment (UE) will begin during a time defined by a measurement event timer;

modifying the low-power period based, at least in part, on the determination, a duration of the measurement event timer, and a duration of the low-power period; and

transmitting a measurement report (MR) associated with the measurement event timer based, at least in part, on the modification.

28. The non-transitory computer readable medium of claim 27 , wherein modifying the low-power period comprises prioritizing the measurement event timer over the low-power period.

29. The non-transitory computer readable medium of claim 27 , wherein modifying the low-power period comprises:

delaying start of the low-power period until expiry of the measurement event timer upon determining enough time remains in the low-power period after transmission of the MR for the UE to enter and exit the low-power period.
