CLAIMS

What is claimed is:

1. A method for wireless communication at a user equipment (UE), comprising:

determining that the UE is operating in a limited power state;

identifying an autonomous uplink (UL) transmission to transmit on a first component carrier (CC) in a shared radio frequency (RF) spectrum band during a time period;

identifying a scheduled UL transmission to transmit on a second CC in a second RF spectrum band during the time period;

identifying a priority configuration used to prioritize between autonomous UL transmissions and scheduled UL transmissions for the limited power state; and

transmitting, to a base station, the autonomous UL transmission or the scheduled UL transmission based at least in part on the identified priority configuration.

2. The method of claim 1, wherein:

the second RF spectrum band is a scheduled RF spectrum band.

3. The method of claim 1, wherein:

the second RF spectrum band is a shared RF spectrum band, or a licensed RF spectrum band, or an unlicensed RF spectrum band, or a combination thereof.

4. The method of claim 1, wherein:

the priority configuration prioritizes the scheduled UL transmission over the autonomous UL transmission.

5. The method of claim 1, wherein:

the priority configuration prioritizes the autonomous UL transmission over the scheduled UL transmission.

6. The method of claim 1, wherein identifying the priority configuration comprises:

receiving the priority configuration from the base station.

7. The method of claim 1, wherein identifying the priority configuration comprises:

8. The method of claim 1, further comprising:

determining to forego transmitting the other one of the autonomous UL transmission or the scheduled UL transmission during the time period based at least in part on the identified priority configuration.

9. The method of claim 1, further comprising:

dropping the other one of the autonomous UL transmission or the scheduled UL transmission based at least in part on the identified priority configuration.

10. The method of claim 1, further comprising:

receiving a radio resource control (RRC) message from the base station, the RRC message indicating the priority configuration used to prioritize between the autonomous UL transmissions and the scheduled UL transmissions.

11. The method of claim 1, wherein:

the time period comprises a subframe, or a slot, or a mini-slot, or a symbol, or a combination thereof.

12. The method of claim 1, wherein:

the limited power state comprises a reduced power mode.

13. The method of claim 1, wherein determining that the UE is operating in the limited power state comprises:

determining that an operating power level of the UE would exceed a power threshold for the UE.

14. A method for wireless communication at a base station, comprising: identifying a priority configuration for a user equipment (UE) to use to prioritize between autonomous uplink (UL) transmissions and scheduled UL transmissions while operating the UE in a limited power state, one or more of the autonomous UL transmissions to be transmitted on a first component carrier (CC) in a shared radio frequency (RF) spectrum band during a time period, and one or more of the scheduled UL transmissions to be transmitted on a second CC in a second RF spectrum band during the time period;

transmitting, to the UE, an indication of the priority configuration; and

15. The method of claim 14, wherein:

the priority configuration prioritizes the autonomous UL transmissions over the scheduled UL transmissions.

16. The method of claim 14, wherein:

the priority configuration prioritizes the scheduled UL transmissions over the autonomous UL transmissions.

17. The method of claim 14, wherein transmitting the indication of the priority configuration comprises:

transmitting a radio resource control (RRC) message to the UE, the RRC message indicating the priority configuration.

18. A method for wireless communication at a user equipment (UE), comprising:

identifying an autonomous uplink (UL) transmission to transmit on a first component carrier (CC) in a shared radio frequency (RF) spectrum band during a time period; and

transmitting, in a power headroom report on a second CC in a second RF spectrum band during the time period, an indication of whether the UE will attempt to transmit the autonomous UL transmission.

19. The method of claim 18, further comprising:

transmitting a scheduled UL transmission on the second CC in the second RF spectrum band during the time period, the scheduled UL transmission including the power headroom report.

20. The method of claim 18, further comprising:

attempting to transmit the identified autonomous UL transmission on the first CC in the shared RF spectrum band during the time period.

21. The method of claim 18, further comprising:

receiving, from a base station, a configuration for autonomous UL transmissions of the UE, wherein the indication of whether the UE will attempt to transmit the autonomous UL transmission is transmitted based at least in part on the received configuration.

22. The method of claim 18, wherein:

the time period comprises a subframe, or a slot, or a mini-slot, or a symbol, or a combination thereof.

23. The method of claim 18, further comprising:

receiving a scheduled UL transmission on the first CC in the second RF spectrum band during the time period, the scheduled UL transmission including the power headroom report.

24. A method for wireless communication at a base station, comprising: receiving a power headroom report from a user equipment (UE) on a first component carrier (CC) in a second RF spectrum band during a time period; and

identifying, based at least in part on the received power headroom report, an indication of whether the UE will attempt to transmit an autonomous uplink (UL) transmission on a second CC in a shared RF spectrum band.

25. The method of claim 24, further comprising:

receiving, during at least a portion of the time period, the autonomous UL transmission on the second CC in the shared RF spectrum band.

26. The method of claim 25, wherein:

the power headroom report from the UE is received as at least a part of the received autonomous UL transmission.

27. The method of claim 25, further comprising:

transmitting, to the UE, a configuration for autonomous UL transmissions of the UE, wherein the autonomous UL transmission is received based at least in part on the transmitted configuration.

28. The method of claim 27, wherein transmitting the configuration for autonomous UL transmissions comprises:

transmitting a radio resource control (RRC) message that identifies the configuration or a default configuration for the power headroom report.

29. The method of claim 27, wherein:

the configuration for autonomous UL transmissions comprises frequency domain resources for the UE to use to transmit autonomous UL transmissions to the base station.

30. The method of claim 24, wherein:

the time period comprises a subframe, or a slot, or a mini-slot, or a symbol, or a combination thereof.
