There are provided measures for common control deactivation in carrier aggregation, said measures exemplarily including a configuration of a secondary carrier for carrier aggregation with a primary carrier of a terminal, including a deactivation of a common control for the secondary carrier, an indication of the deactivation of the common control for the secondary carrier via the primary carrier, and a signaling of control information, substituting control information of the deactivated common control, for facilitating selection of or operation on the secondary carrier without the deactivated common control via the primary carrier from a base station to the terminal. Said measures may exemplarily be applied for common control deactivation in carrier aggregation in heterogeneous network environments based on LTE, LTE-Advanced, HSPA and/or UMTS radio access systems.
