Abstract

Claims (42)

1. A method of wireless communication performed by a user equipment (UE), comprising:

transmitting, to a network unit, a capability report of the UE, the capability report specifying a first value for a physical downlink control channel (PDCCH) monitoring parameter, wherein the PDCCH monitoring parameter is one of a maximum number of monitored PDCCH candidates or a maximum number of non-overlapping control channel elements (CCEs);

transmitting, to the network unit in response to a trigger based on a current operating parameter of the UE, a PDCCH monitoring configuration request including a second value for the PDCCH monitoring parameter less than the first value based on the current operating parameter of the UE;

receiving, from the network unit, a response to the PDCCH monitoring configuration request including a third value for the PDCCH monitoring parameter different than the second value, wherein the response includes an indication indicating a set of selected PDCCH candidate indices based on priorities of PDCCH candidates associated with a PDCCH candidate index; and

monitoring for a PDCCH using the third value for the PDCCH monitoring parameter.

2. The method of claim 1 , wherein the PDCCH monitoring parameter includes a maximum number of monitored PDCCH candidates per-slot that is supported by the UE.

3. The method of claim 1 , wherein the PDCCH monitoring parameter includes a maximum number of monitored PDCCH candidates for a span that is supported by the UE, the span having a periodicity and a duration specifying a period of time defined in terms of symbols.

4. The method of claim 1 , wherein the PDCCH monitoring parameter includes a maximum number of non-overlapping control channel elements (CCEs) per-slot that is supported by the UE.

5. The method of claim 1 , wherein the PDCCH monitoring parameter includes a maximum number of non-overlapping CCEs for a span that is supported by the UE, the span having a periodicity and a duration specifying a period of time defined in terms of symbols.

6. The method of claim 1 , wherein the transmitting the PDCCH monitoring configuration request includes transmitting the PDCCH monitoring configuration request via a media access control-control element (MAC-CE), a radio resource control (RRC) message, or uplink control information (UCI).

7. The method of claim 1 , wherein the current operating parameter is related to current operations at the UE.

8. The method of claim 7 , wherein the current operating parameter includes at least one of channel characteristics, battery usage at the UE, a remaining battery life at the UE, or traffic patterns at the UE.

9. A user equipment (UE), comprising:

a memory;

a transceiver; and

at least one processor coupled to the memory and the transceiver, wherein the at least one processor is configured, alone or in any combination, to cause the UE to:

transmit, to a network unit, a capability report of the UE, the capability report specifying a first value for a physical downlink control channel (PDCCH) monitoring parameter, wherein the PDCCH monitoring parameter is one of a maximum number of monitored PDCCH candidates or a maximum number of non-overlapping control channel elements (CCEs);

transmit, to the network unit in response to a trigger based on a current operating parameter of the UE, a PDCCH monitoring configuration request including a second value for the PDCCH monitoring parameter less than the first value based on the current operating parameter of the UE;

receive a response to the PDCCH monitoring configuration request including a third value for the PDCCH monitoring parameter different than the second value, wherein the response includes an indication indicating a set of selected PDCCH candidate indices based on priorities of PDCCH candidates associated with a PDCCH candidate index; and

monitor for a PDCCH using the third value for the PDCCH monitoring parameter.

10. The UE of claim 9 , wherein the PDCCH monitoring parameter includes a maximum number of monitored PDCCH candidates per-slot that is supported by the UE.

11. The UE of claim 9 , wherein the PDCCH monitoring parameter includes a maximum number of monitored PDCCH candidates for a span that is supported by the UE, and wherein the span has a periodicity and a duration specifying a period of time defined in terms of symbols.

12. The UE of claim 9 , wherein the PDCCH monitoring parameter includes a maximum number of non-overlapping control channel elements (CCEs) per-slot that is supported by the UE.

13. The UE of claim 9 , wherein the PDCCH monitoring parameter includes a maximum number of non-overlapping CCEs for a span that is supported by the UE, and wherein the span has a periodicity and a duration specifying a period of time defined in terms of symbols.

14. The UE of claim 9 , wherein the UE is further configured to:

transmit the PDCCH monitoring configuration request via a media access control-control element (MAC-CE), a radio resource control (RRC) message, or uplink control information (UCI).

15. The UE of claim 9 , wherein the current operating parameter is related to current operations at the UE.

16. The UE of claim 15 , wherein the current operating parameter includes at least one of channel characteristics, battery usage at the UE, a remaining battery life at the UE, or traffic patterns at the UE.

17. A non-transitory computer-readable medium having program code recorded thereon executable by one or more processors for wireless communication by a user equipment (UE), the program code comprising:

code for causing the UE to transmit, to a network unit, a capability report of the UE, the capability report specifying a first value for a physical downlink control channel (PDCCH) monitoring parameter, wherein the PDCCH monitoring parameter is one of a maximum number of monitored PDCCH candidates or a maximum number of non-overlapping control channel elements (CCEs);
