1. A method for wireless communication implemented by a user equipment (UE), comprising:

identifying that the UE is in carrier aggregation communication with a primary cell and a secondary cell;

monitoring, during one or more time intervals, UE-specific search spaces of the secondary cell for control information scheduling data communications on the primary cell; and

switching, during one or more different time intervals, from monitoring the UE-specific search spaces of the secondary cell to monitoring UE-specific search spaces of the primary cell for the control information scheduling the data communications on the primary cell.
