A user equipment (UE) configured for multi-slot physical downlink control channel (PDCCH) monitoring may decode higher-layer signalling comprising configuration information received from a gNodeB (gNB) that configure the UE with search space (SS) sets for multi-slot PDCCH monitoring. At least some slots of the SS sets may be indicated to have a PDCCH monitoring occasion (MO). A SS set may be configured in a number (Y) of consecutive non-overlapping slots (MO slots) within slot groups of a number (X) of consecutive non-overlapping slots. The number (X) of consecutive slots of the slot group may be at least twice the number (Y) of consecutive MO slots within each SS set. The number (X) of consecutive slots of the slot group and the number (Y) of consecutive MO slots within each SS set that comprise the PDCCH MO may also be based on a subcarrier spacing (SCS).
