Abstract: A method for operating a user equipment (UE) includes receiving a configuration for a set of search space sets and receiving a PDCCH that provides a downlink control information (DCI) format. A search space set provides parameters for physical downlink control channel (PDCCH) receptions. The parameters include time-frequency resources of a control resource set (CORESET) for the PDCCH receptions and a group index for the CORESET. The DCI format includes a field providing an indication of a CORESET group index. The method further includes determining based on the indication, a group of search space sets and receiving PDCCHs according to the group of search space sets. The group of search space sets includes each search space set from the set of search space sets that is associated with a CORESET having the CORESET group index.

Abstract: A UE includes a receiver configured to receive a first configuration for a first CORESET, a second configuration for a reception of a first CSI-RS, and the first CSI-RS. The first configuration includes a first TCI state. The TCI state for a CORESET indicates a set of quasi co-location properties for a PDCCH reception in the CORESET. A PDCCH includes a DCI format. The second configuration includes a first set of REs and the first TCI state. The UE also includes a processor operably connected to the receiver. The processor is configured to compute a first CQI value, based on the first CSI-RS, for a first PDCCH reception in the first CORESET and at least one CQI value based on the first CQI value. The UE further includes a transmitter operably connected to the processor, the transmitter configured to transmit a channel that includes the at least one CQI value.

Abstract: Apparatuses and methods for cross-carrier scheduling across different discontinuous reception (DRX) groups. A method includes receiving first information for a first and second sets of values for a first set of DRX timers associated with first and second DRX cell groups, respectively; receiving second information, from a first cell, for scheduling on a second cell; and receiving a physical downlink control channel (PDCCH) on the first cell. The first and second DRX cell groups do not have a common cell. The first and second cells are from the first and second DRX cell groups, respectively. The method further includes determining a first DRX Active time for the first DRX cell group based on the first set of values and the PDCCH reception and determining a second DRX Active time for the second DRX cell group based on the second set of values and the PDCCH reception.
