Search space configurations and pdcch monitoring with multi-cell scheduling dci

A user equipment (UE), comprising:

• a memory;
• and
• one or more processors configured to, when executing instructions stored in the memory, cause the UE to:
• receive a radio resource control (RRC) signaling comprising at least one control channel element (CCE) offset indicator mapped to a respective search space set and a respective component carrier (CC) associated with a scheduled cell of one or more scheduled cells;
• determine, based on the CCE offset indicator, CCE resources associated with one or more physical downlink control channel (PDCCH) candidates;
• perform blind decoding of the one or more PDCCH candidates to decode one or more multi-cell downlink control information (mcDCI) transmitted by a scheduling cell;
• and
• determine, from the one or more mcDCI, uplink (UL)/downlink (DL) CCs.

A base station (BS), comprising:

• a memory;
• and
• one or more processors configured to, when executing instructions stored in the memory, cause the BS:
• generate a radio resource control (RRC) signal comprising at least one control channel element (CCE) offset indicator mapped to a respective search space set and a respective component carrier (CC) associated with a scheduled cell, and a CCE offset indicator is associated with a CCE resource, wherein
• the CCE offset indicator and CC are related to one or more physical downlink control channel (PDCCH) candidates, the one or more PDCCH candidates comprising one or more multi-cell downlink control information (mcDCI);
• and
• transmit, by a radio frequency (RF) circuitry, the RRC signal comprising the mapping of the CCE offset indicators, CCs, and search space sets.
