    Abstract: The present invention relates to a method and an apparatus for controlling uplink transmission power of a user equipment. In the method, a serving base station receives from the user equipment a signal measurement report for a first neighboring base station transmitting the strongest signal to the user equipment, transmits, to the user equipment, a control signal including a path loss information for calculating the uplink transmission power, transmits, to the user equipment and the first neighboring base station scheduling information for the user equipment and receives, from the first neighboring base station, an uplink signal of the user equipment. According to the method, the uplink transmission power can be adjusted based on a pico base station close to the user equipment when the macro base station is a serving base station such that the amount of interference power of a multi cell may be minimized.

    Abstract: The present invention relates to a method and apparatus for transmitting and receiving data using a plurality of carriers in a mobile communication system. The communication method by a terminal according to one embodiment of the present invention includes the steps of: receiving a secondary cell (SCell) adding command including setting information on an SCell to be added from a primary serving cell (PCell); transmitting a preamble to the SCell to be added; receiving a random access response message (RAR) for the SCell to be added; and, if the SCell adding command includes an indicator indicating that a first base station to which the SCell to be added belongs and a base station to which the PCell belongs are different from each other, applying parameters included in the RAR to the SCell that transmits the RAR. According to the embodiment of the present invention, by aggregating carriers between different base stations, a terminal can have increased chances of transmitting and receiving data at high speed through the carrier aggregation.
