Abstract
Various embodiments may relate to physical downlink control channel (PDCCH) monitoring in association with cross-carrier scheduling. In particular, some embodiments are directed to scheduling a transmission on a primary cell (PCell) or primary secondary cell (PSCell) considering secondary cell (SCell) dormancy switching or SCell activation states. Other embodiments may be disclosed or claimed.

An apparatus of a user equipment (UE) comprising:
- memory to store configuration information for cross-carrier scheduling (CCS) from a scheduling secondary cell (sSCell) to a primary cell (PCell) or a primary secondary cell (PSCell) by the UE;
- and
- processor circuitry, coupled with the memory, to:
- retrieve the configuration information from the memory, wherein the configuration information includes information for physical downlink control channel (PDCCH) monitoring by the UE based on one or more of:
- whether the sSCell is active, and whether the sScell is dormant;
- determine, based on the configuration information, a maximum number of monitored PDCCH candidates;
- and
- monitor for PDCCH based on the determined maximum number of PDCCH candidates.
One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause a user equipment (UE) to:
- receive, via radio resource control (RRC) signaling or a medium access control (MAC) control element (CE), configuration information for cross-carrier scheduling (CCS) from a scheduling secondary cell (sSCell) to a primary cell (PCell) or a primary secondary cell (PSCell) by the UE, wherein the configuration information includes information for physical downlink control channel (PDCCH) monitoring by the UE based on one or more of:
- whether the sSCell is active, and whether the sScell is dormant;
- determine, based on the configuration information, a maximum number of monitored PDCCH candidates;
- and
- monitor for PDCCH based on the determined maximum number of PDCCH candidates.
One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause a user equipment (UE) to:
- determine, based on configuration information for cross-carrier scheduling (CCS) from a scheduling secondary cell (sSCell) to a primary cell (PCell) or a primary secondary cell (PSCell) by the UE, a maximum number of monitored physical downlink control channel (PDCCH) candidates, wherein the configuration information is predefined and includes information for PDCCH monitoring by the UE based on one or more of:
- whether the sSCell is active, and whether the sScell is dormant;
- and
- monitor for PDCCH based on the determined maximum number of PDCCH candidates.
