Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may signal, to a base station, an indication that fast sleep is supported by the UE with regard to an inter-slot scheduling configuration or a non-self-contained slot configuration; and receive, based at least in part on signaling the indication that the fast sleep is supported by the UE, signaling indicating the inter-slot scheduling configuration or the non-self-contained slot configuration for the fast sleep, wherein the fast sleep is between at least one of a data grant and a corresponding data communication for the inter-slot scheduling, or a data communication and acknowledgment (ACK)/negative ACK (NACK) feedback regarding the data communication for the non-self-contained slot configuration. Numerous other aspects are provided.

First claim

What is claimed is:

1. A method of wireless communication performed by a user equipment (UE), comprising:
signaling, to a base station, an indication that fast sleep is supported by the UE with regard to an inter-slot scheduling configuration or a non-self-contained slot configuration,
wherein at least one of:
the indication indicates that a quality of service threshold or a user perception threshold is satisfied when the inter-slot scheduling configuration or the non-self-contained slot configuration for fast sleep is to be used, or
the indication identifies at least one of a minimum number of slots or a maximum number of slots associated with the fast sleep; and

receiving signaling indicating the inter-slot scheduling configuration or the non-self-contained slot configuration for the fast sleep, wherein the fast sleep is between at least one of:
a data grant and a corresponding data communication for the inter-slot scheduling, or
a data communication and acknowledgment (ACK)/negative ACK (NACK) feedback regarding the data communication for the non-self-contained slot configuration.

2. The method of claim 1 , wherein the indication identifies one or more minimum values for a delay for the fast sleep between the data grant and the corresponding data communication, or between the data communication and the ACK/NACK feedback.

3. The method of claim 1 , wherein the indication indicates that the quality of service threshold or the user perception threshold is satisfied when the inter-slot scheduling configuration or the non-self-contained slot configuration for fast sleep is to be used.

4. The method of claim 3 , wherein the indication indicates one or more minimum values for a delay for the fast sleep between the data grant and the corresponding data communication, or between the data communication and the ACK/NACK feedback, and wherein the quality of service threshold or the user perception threshold is satisfied when the one or more minimum values for the delay are used.

5. The method of claim 1 , wherein the indication identifies at least one of the minimum number of slots or the maximum number of slots associated with the fast sleep.

6. The method of claim 1 , wherein the data grant is associated with a physical downlink control channel (PDCCH) and the corresponding data communication is associated with a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH).

7. The method of claim 1 , wherein the data communication is associated with a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH), and wherein the ACK/NACK feedback is associated with a hybrid automatic repeat request (HARD) process for the PDSCH or the PUSCH.

8. The method of claim 1 , wherein the signaling indicating the inter-slot scheduling configuration or the non-self-contained slot configuration for the fast sleep is received based at least in part on signaling the indication that the fast sleep is supported by the UE.

9. The method of claim 1 , further comprising:
determining the quality of service threshold or the user perception threshold will be satisfied if fast sleep is performed, and
wherein the indication that fast sleep is supported by the UE is signaled to the base station based at least in part on determining the quality of service threshold or the user perception threshold will be satisfied if fast sleep is performed.

10. A method of wireless communication performed by a base station, comprising:
receiving, from a user equipment (UE), an indication that fast sleep is supported by the UE with regard to an inter-slot scheduling configuration or a non-self-contained slot configuration,
wherein at least one of:
the indication indicates that a quality of service threshold or a user perception threshold is satisfied when the inter-slot scheduling configuration or the non-self-contained slot configuration for fast sleep is to be used, or
the indication identifies at least one of a minimum number of slots or a maximum number of slots associated with the fast sleep; and

signaling the inter-slot scheduling configuration or the non-self-contained slot configuration for the fast sleep, wherein the fast sleep is to be performed between at least one of:
a data grant and a corresponding data communication for the inter-slot scheduling, or
a data communication and acknowledgment (ACK)/negative ACK (NACK) feedback regarding the data communication for the non-self-contained slot configuration.

11. The method of claim 10 , wherein the indication identifies at least one of the minimum number of slots or the maximum number of slots associated with the fast sleep, and wherein the inter-slot scheduling configuration or the non-self-contained slot configuration is based at least in part on the minimum number of slots or the maximum number of slots.

12. The method of claim 10 , wherein the indication identifies one or more minimum values for a delay for the fast sleep between the data grant and the corresponding data communication, or between the data communication and the ACK/NACK feedback.

13. The method of claim 10 , wherein the indication indicates that the quality of service threshold or the user perception threshold is satisfied when the inter-slot scheduling or the non-self-contained slot configuration with fast sleep is to be performed.

14. The method of claim 13 , wherein the indication indicates one or more minimum values for a delay for the fast sleep between the data grant and the corresponding data communication, or between the data communication and the ACK/NACK feedback, and wherein the quality of service threshold or the user perception threshold is satisfied when the one or more minimum values for the delay are used.

15. The method of claim 10 , wherein the data grant is associated with a physical downlink control channel (PDCCH) and the corresponding data communication is associated with a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH).

16. The method of claim 10 , wherein the data communication is associated with a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH), and wherein the ACK/NACK feedback is associated with a hybrid automatic repeat request (HARQ) process for the PDSCH or the PUSCH.

17. The method of claim 10 , wherein the inter-slot scheduling configuration or the non-self-contained slot configuration is signaled based at least in part on a determination that the inter-slot scheduling or the non-self-contained slot configuration is to be performed, and wherein the determination is based at least in part on the indication.

18. The method of claim 10 , wherein the inter-slot scheduling configuration or the non-self-contained slot configuration for the fast sleep is signaled based at least in part on receiving the indication that the fast sleep is supported by the UE.

19. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors coupled to the memory, the memory and the one or more processors configured to:
signal, to a base station, an indication that fast sleep is supported by the UE with regard to an inter-slot scheduling configuration or a non-self-contained slot configuration,
wherein at least one of:
the indication indicates that a quality of service threshold or a user perception threshold is satisfied when the inter-slot scheduling configuration or the non-self-contained slot configuration for fast sleep is to be used, or
the indication identifies at least o
