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

  • receiving a carrier aggregation capability message from a selected user equipment (UE) at an enhanced Node B (eNode B) configured to provide service for a plurality of UEs within the eNode B′

    s network, wherein the carrier aggregation capability message includes a plurality of carrier aggregation capabilities of the UE;

    configuring a plurality of component carriers at the eNode B for the selected UE based on the carrier aggregation capability message of the selected UE;

    broadcasting from the eNode B a component carrier configuration message containing component carrier configuration information that is common to the plurality of UEs;

    communicating from the eNode B component carrier configuration information that is specific to one of the plurality of UEs using dedicated communication signaling to form configured component carriers; and

    activating or deactivating selected configured component carriers at the eNode B for the selected UE based on bandwidth and quality of service needs of the selected UE, wherein the selected configured component carriers are activated or deactivated by transmitting a bitmap from the eNodeB to the UE that includes bits to indicate the selected configured component carriers that are activated or deactivated, wherein the selected component carriers are deactivated based on selected deactivated rules, wherein the selected deactivation rules include at least a predetermined time period a selected component carrier has not be used to transmit data to the selected UE.
