1. A method for configuring carriers in carrier aggregation, comprising:

  • scanning by a user equipment (UE) for an enhanced Node B (eNode B) operable in a wireless network;

    selecting by the UE an eNode B;

    attaching the UE to an available carrier provided by the eNode B and designating the available carrier as a Primary Component Carrier (PCC), wherein the PCC is configured as a component carrier pair comprising a downlink primary component carrier (DL PCC) and an uplink primary component carrier (UL PCC);

    receiving at the UE mobility management and security input information from the eNode B via the DL PCC and the UL PCC; and

    transmitting to the eNode B a carrier aggregation capability from the UE to enable the eNode B to configure a plurality of secondary component carriers (SCCs) at the eNode B for the UE based on the carrier aggregation capability of the UE.
