Control channel monitoring configurations for cross-carrier scheduling

A method of wireless communication performed by a base station (B S), the method comprising:

• transmitting, to a user equipment (UE), a first configuration for scheduling in a first cell, the first configuration comprising a first monitoring parameter associated with a search space in a second cell different than the first cell, wherein the first monitoring parameter is based on a first subcarrier spacing (SCS) associated with the first cell;
• transmitting, to the UE, a second configuration for scheduling in the second cell, the second configuration comprising a second monitoring parameter associated with the search space in the second cell, wherein the second monitoring parameter is different than the first monitoring parameter, and wherein the second monitoring parameter is based on a second SCS associated with the second cell, the second SCS being different from the first SCS;
• and
• transmitting, to the UE via the second cell based on the first monitoring parameter and monitoring parameter, downlink control information (DCI) comprising a scheduling grant for a transmission in the first cell.

A user equipment (UE), comprising:

• a transceiver configured to:
• receive, from a base station (BS), a first configuration for scheduling in a first cell, the first configuration comprising a first monitoring parameter associated with a search space in a second cell different than the first cell, wherein the first monitoring parameter is based on a first subcarrier spacing (SCS) associated with the first cell;
• and
• receive, from the BS, a second configuration for scheduling in the second cell, the second configuration comprising a second monitoring parameter associated with the search space in the second cell, wherein the second monitoring parameter is different than the first monitoring parameter, and wherein the second monitoring parameter is based on a second SCS associated with the second cell, the second SCS being different from the first SCS;
• and
• a processor in communication with the transceiver and configured to:
• monitor, in the search space in the second cell based on the first monitoring parameter and the second monitoring parameter, for downlink control information (DCI) comprising a scheduling grant for a transmission in the first cell.
