Systems, methods, apparatuses, and computer program products for aperiodic channel state information (CSI) reporting for enhanced carrier aggregation are provided. One method includes transmitting, by a network node, a configuration of at least two aperiodic channel state information (A-CSI) reporting modes per one or more configured downlink (DL) component carriers (CC) to at least one user equipment. The method may also include transmitting an aperiodic channel state information (A-CSI) trigger to the at least one user equipment. The transmitting of the A-CSI trigger may cause the at least one user equipment to dynamically switch between the two configured aperiodic channel state information (A-CSI) reporting modes.
