1. A method for activating or deactivating, by a user equipment, a cell associated with a second base station, the method comprising:

  • receiving, by the user equipment, a higher layer signaling through a first base station after signaling between the first base station and the second base station, wherein the higher layer signaling includes information on a cell configuration associated with the second base station;

    configuring a cell associated with the second base station to be in an active state, based on the received higher layer signaling;

    configuring a radio bearer through the second base station; and

    controlling, by the user equipment, a cell activation or a cell deactivation,wherein the first base station is a macrocell base station and the second base station is a small cell base station;

    wherein the information on the cell configuration associated with the second base station comprises second base station-associated cell addition/modification configuration information that includes one of cell activation or deactivation indication information of a cell associated with the second base station and cell information associated with a cell that is to be maintained in an active state; and

    wherein the controlling includes;

    receiving, from the second base station, activation-related indication information including information for instructing to activate or deactivate a cell different than the configured cell among cells associated with the second base station; and

    controlling activation or deactivation of the different cell based on the received activation-related indication information.
