Method and apparatus for PDCCH monitoring
A method for PDCCH monitoring performed by a UE is provided. The method includes performing the PDCCH monitoring in a first group associated with at least one first PDCCH monitoring configuration; receiving, from a base station, DCI comprising an indicator; performing the PDCCH monitoring in a second group associated with at least one second PDCCH monitoring configuration; and stopping the PDCCH monitoring in the first group after receiving the indicator.
1. A user equipment (UE) performing physical downlink control channel (PDCCH) monitoring, the UE comprising:
one or more non-transitory computer-readable media storing one or more computer-executable instructions; and
at least one processor coupled to the one or more non-transitory computer-readable media, the at least one processor configured to execute the computer-executable instructions to:
perform the PDCCH monitoring in a first group associated with at least one first PDCCH monitoring configuration;
receive, from a base station, downlink control information (DCI) comprising an indicator;
perform the PDCCH monitoring in a second group associated with at least one second PDCCH monitoring configuration in response to reception of the indicator; and
stop the PDCCH monitoring in the first group in response to the reception of the indicator,
wherein a time period between receiving the DCI comprising the indicator and performing the PDCCH monitoring in the second group is associated with a delay value configured in a radio resource control (RRC) configuration.
2. The UE of claim 1 , wherein the at least one processor is further configured to execute the one or more computer-executable instructions to:
stop the PDCCH monitoring in the second group after a timer expires.
3. The UE of claim 2 , wherein the timer is configured by the RRC configuration.
4. The UE of claim 1 , wherein the indicator corresponds to an index of the second group.
5. The UE of claim 1 , wherein each of the at least one first PDCCH monitoring configuration and the at least one second PDCCH monitoring configuration corresponds to a search space set identity (ID).
6. The UE of claim 1 , wherein each of the first group and the second group corresponds to at least one PDCCH monitoring occasion within a configured duration.
7. A method for physical downlink control channel (PDCCH) monitoring performed by a user equipment (UE), the method comprising:
performing the PDCCH monitoring in a first group associated with at least one first PDCCH monitoring configuration;
receiving, from a base station, downlink control information (DCI) comprising an indicator;
performing the PDCCH monitoring in a second group associated with at least one second PDCCH monitoring configuration in response to reception of the indicator; and
stopping the PDCCH monitoring in the first group in response to the reception of the indicator,
wherein a time period between receiving the DCI comprising the indicator and performing the PDCCH monitoring in the second group is associated with a delay value configured in a radio resource control (RRC) configuration.
8. The method of claim 7 , further comprising:
stopping the PDCCH monitoring in the second group after a timer expires.
9. The method of claim 8 , wherein the timer is configured by the RRC configuration.
10. The method of claim 7 , wherein the indicator corresponds to an index of the second group.
11. The method of claim 7 , wherein each of the at least one first PDCCH monitoring configuration and the at least one second PDCCH monitoring configuration corresponds to a search space set identity (ID).
12. The method of claim 7 , wherein each of the first group and the second group corresponds to at least one PDCCH monitoring occasion within a configured duration.
