Abstract

Certain aspects of the present disclosure generally relate to methods and apparatus for minimum scheduling delay signaling.

Claims (53)

1. A method for wireless communications by a network entity, comprising:

determining a minimum threshold for a scheduling parameter that indicates a scheduling delay between an end of a physical downlink control channel (PDCCH) transmission and a beginning of a transmission scheduled by the PDCCH; and

configuring a user equipment (UE) with the minimum threshold, wherein one or multiple values of the minimum threshold is configured on a per bandwidth part (BWP) basis.

2. The method of claim 1 , wherein:

a value of the minimum threshold depends, at least in part, on a power savings state of the UE.

3. The method of claim 2 , wherein the minimum threshold has a larger value during an ON duration of a lower power than when an inactivity timer of the lower power state is counting.

4. The method of claim 1 , wherein the scheduled transmission comprises an uplink transmission.

5. The method of claim 4 , wherein the uplink transmission comprises at least one sounding reference signal (SRS) transmitted on the uplink after an aperiodic SRS (A-SRS) request is triggered.

6. The method of claim 1 , wherein the scheduled transmission comprises a downlink transmission.

7. The method of claim 6 , wherein the downlink transmission comprises at least one channel state information reference signals (CSI-RS) transmitted on the downlink after an aperiodic CSI (A-CSI) request is triggered.

8. The method of claim 1 , further comprising providing signaling indicating the minimum threshold.

9. The method of claim 8 , wherein the signaling indicates a selection from a set of values for the minimum threshold value.

10. The method of claim 9 , wherein:

the set of values is indicated via radio resource control (RRC) signaling; and

the method further comprises providing signaling selecting one of the set of values via at least one of: media access control (MAC) control element (CE) or DCI signaling.

11. The method of claim 9 , further comprising selecting one of the values based on a traffic load.

12. The method of claim 1 , wherein a value of the minimum threshold is signaled per BWP.

13. The method of claim 1 , wherein determination of the minimum threshold is performed in orthogonal frequency division multiplexed (OFDM) symbol resolution or slot resolution, based on a numerology of the PDCCH or the numerology of the transmission scheduled by the PDCCH.

14. The method of claim 1 , further comprising:

transmitting a physical downlink control channel (PDCCH) transmission with downlink control information (DCI) signaling the scheduling parameter indicating the scheduling delay; and

communicating the transmission scheduled by the PDCCH.

15. The method of claim 14 , wherein the value of the scheduling parameter is not below the minimum threshold.

16. An apparatus for wireless communications by a network entity, comprising:

means for determining a minimum threshold for a scheduling parameter that indicates a scheduling delay between an end of a physical downlink control channel (PDCCH) transmission and a beginning of a transmission scheduled by the PDCCH; and

means for configuring a user equipment (UE) with the minimum threshold, wherein one or multiple values of the minimum threshold is configured on a per bandwidth part (BWP) basis.

17. An apparatus for wireless communications comprising:

a processor;

memory coupled with the processor; and

instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:

determine a minimum threshold for a scheduling parameter that indicates a scheduling delay between an end of a physical downlink control channel (PDCCH) transmission and a beginning of a transmission scheduled by the PDCCH; and

configure a user equipment (UE) with the minimum threshold, wherein one or multiple values of the minimum threshold is configured on a per bandwidth part (BWP) basis.

18. The apparatus of claim 17 , wherein:

a value of the minimum threshold depends, at least in part, on a power savings state of the UE.

19. The apparatus of claim 18 , wherein the minimum threshold has a larger value during an ON duration of a lower power than when an inactivity timer of the lower power state is counting.

20. The apparatus of claim 17 , wherein the scheduled transmission comprises an uplink transmission.

21. The apparatus of claim 20 , wherein the uplink transmission comprises at least one sounding reference signal (SRS) transmitted on the uplink after an aperiodic SRS (A-SRS) request is triggered.

22. The apparatus of claim 17 , wherein the scheduled transmission comprises a downlink transmission.

23. The apparatus of claim 22 , wherein the downlink transmission comprises at least one channel state information reference signals (CSI-RS) transmitted on the downlink after an aperiodic CSI (A-CSI) request is triggered.

24. The apparatus of claim 17 , further comprising instructions operable to cause the apparatus to provide signaling indicating the minimum threshold.

25. The apparatus of claim 24 , wherein the signaling indicates a selection from a set of values for the minimum threshold value.

26. The apparatus of claim 25 , wherein:

the set of values is indicated via radio resource control (RRC) signaling; and

the apparatus further comprises instructions operable to cause the apparatus to provide signaling selecting one of the set of values via at least one of: media access control (MAC) control element (CE) or DCI signaling.

27. The apparatus of claim 25 , further comprising instructions operable to cause the apparatus to select one of the values based on a traffic load.

28. The apparatus of claim 17 , wherein a value of the minimum threshold is signaled per BWP.

29. The apparatus of claim 17 , wherein determination of the minimum threshold is performed in orthogonal frequency division multiplexed (OFDM) symbol resolution or slot resolution, based on a numerology of the PDCCH or the numerology of the transmission scheduled by the PDCCH.

30. The apparatus of claim 17 , further comprising instructions operable to cause the apparatus to:

transmit a physical downlink control channel (PDCCH) transmission with downlink control information (DCI) signaling the scheduling parameter indicating the scheduling delay; and

communicate the transmission scheduled by the PDCCH.

31. The apparatus of claim 30 , wherein the value of the scheduling parameter is not below the minimum threshold.

32. A non-transitory computer-readable medium having instructions stored thereon which, when executed by a processor, performs an operation for wireless communications by a network entity, the operation comprising:

determining a minimum threshold for a scheduling parameter that indicates a scheduling delay between an end of a physical downlink control channel (PDCCH) transmission and a beginning of a transmission scheduled by the PDCCH; and

configuring a user equipment (UE) with the minimum threshold, wherein one or multiple values of the minimum threshold is configured on a per bandwidth part (BWP) basis.
