Wake-up behavior indication for power saving

1. A method of wireless communication, comprising:

transmitting, by a base station (BS) to a user equipment (UE), a default wake-up configuration associated with a discontinuous reception (DRX) operation;

determining, by the BS, to refrain from transmitting a wake-up signal (WUS) to the UE during a WUS occasion based on a traffic load; and

transmitting, by the BS, a physical downlink control channel (PDCCH) signal during a duration associated with the WUS occasion.

2. The method of claim 1 , wherein the determining to refrain from transmitting the WUS to the UE during the WUS occasion based on the traffic load comprises:

determining to refrain from transmitting the WUS to the UE during the WUS occasion based on the traffic load being below a first threshold.

3. The method of claim 1 , wherein the duration associated with the WUS occasion includes one or more discontinuous reception (DRX) on-durations associated with the WUS occasion.

4. The method of claim 1 , wherein the transmitting the default wake-up configuration includes:

transmitting, by the BS to the UE, the default wake-up configuration via at least one of radio resource control (RRC) signaling, PDCCH signaling, or media access control (MAC) control element (CE) signaling.

5. The method of claim 1 , wherein the transmitting the default wake-up configuration includes:

transmitting, by the BS to the UE, the default wake-up configuration during the WUS occasion.

6. The method of claim 1 , wherein the transmitting the default wake-up configuration includes:

transmitting, by the BS to the UE, the default wake-up configuration having an indication for the UE to operate in a first wake-up configuration or operate in a second wake-up configuration, the second wake-up configuration being different than the first wake-up configuration.

7. The method of claim 1 , wherein the transmitting the default wake-up configuration includes:

transmitting, by the BS to the UE, the default wake-up configuration having an indication for the UE to operate, based on a timer, in a first wake-up configuration or a second wake-up configuration.

8. The method of claim 1 , wherein the transmitting the default wake- up configuration includes:

transmitting, by the BS, the default wake-up configuration to a group of UEs, including the UE, based on one or more of a bandwidth part (BWP) or a carrier associated with the group of UEs.

9. The method of claim 1 , wherein the transmitting the default wake- up configuration includes:

transmitting, by the BS to the UE, the default wake-up configuration having an indication for one or more of an aperiodic channel state reference signal (A-CSI-RS) triggering, a PDCCH monitoring reduction, a bandwidth part (BWP) switch, or a secondary cell (Scell) wake-up.

10. A base station, comprising:

at least one memory;

at least one transceiver; and

at least one processor coupled to the at least one memory and the at least one transceiver, wherein the base station is configured to:

transmit, to a user equipment (UE), a default wake-up configuration associated with a discontinuous reception (DRX) operation;

transmit a physical downlink control channel (PDCCH) signal during a duration associated with a wake-up signal (WUS) occasion; and

determine to refrain from transmitting a WUS to the UE during the WUS occasion based on a traffic load.

11. The base station of claim 10 , wherein the base station is configured to:

determine to refrain from transmitting the WUS to the UE during the WUS occasion based on the traffic load being below a first threshold.

12. The base station of claim 10 , wherein the duration associated with the WUS occasion includes one or more discontinuous reception (DRX) on-durations associated with the WUS occasion.

13. The base station of claim 10 , wherein the base station is further configured to:

transmit, to the UE, the default wake-up configuration via at least one of radio resource control (RRC) signaling, PDCCH signaling, or media access control (MAC) control element (CE) signaling.

14. The base station of claim 10 , wherein the base station is further configured to:

transmit, to the UE, the default wake-up configuration during the WUS occasion.

15. The base station of claim 10 , wherein the base station is further configured to:

transmit, to the UE, the default wake-up configuration having an indication for the UE to operate in a first wake-up configuration or operate in a second wake-up configuration, the second wake-up configuration being different than the first wake-up configuration.

16. The base station of claim 15 , wherein the base station is further configured to:

transmit, to the UE, the default wake-up configuration having an indication for the UE to operate, based on a timer, in the first wake-up configuration or the second wake-up configuration.

17. The base station of claim 10 , wherein the base station is further configured to:

transmit the default wake-up configuration to a group of UEs, including the UE, based on one or more of a bandwidth part (BWP) or a carrier associated with the group of UEs.

18. The base station of claim 10 , wherein the base station is further configured to:

transmit, to the UE, the default wake-up configuration having an indication for one or more of an aperiodic channel state reference signal (A-CSI-RS) triggering, a PDCCH monitoring reduction, a bandwidth part (BWP) switch, or a secondary cell (Scell) wake-up.

19. A non-transitory computer-readable medium having program code recorded thereon, the program code comprising:

code for causing a base station (BS) to transmit, to a user equipment (UE), a default wake-up configuration associated with a discontinuous reception (DRX) operation;

code for causing the BS to determine to refrain from transmitting a wake-up signal (WUS) to the UE during a WUS occasion based on a traffic load; and

code for causing the BS to transmit a physical downlink control channel (PDCCH) signal during a duration associated with the WUS occasion.

20. The non-transitory computer-readable medium of claim 19 , wherein the determining whether to transmit the WUS to the UE during the WUS occasion based on the traffic load includes at least one of:

code for causing the BS to determine not to transmit the WUS to the UE during the WUS occasion based on the traffic load being below a first threshold; or

code for causing the BS to determine to transmit the WUS to the UE during the WUS occasion based on the traffic load being above a second threshold.
